Among the leading health problems in India is malnutrition. Malnutrition results in weak immune system and growth and cognitive delay. A descriptive study was conducted to assess the nutritional status of school going children in the age group of 6 -13 years in a selected school of Delhi. Methodology: A total of 211 children were selected through purposive sampling technique. Structured questionnaire and a record sheet were used to collect the data. Height, weight and Blood Pressure of children were measured by using inch-tape, weighing scale, sphygmomanometer respectively. Descriptive and inferential statistics were employed to interpret the data. Out of 211 school going children, 144 (66.2 %) were in the age group 6 to 9 years and 67 (31.8 %) were in the 10-13 years age group. In the age group of 6 to 9 years, 140 were underweight and 1 was overweight and rest 3 had normal weight as per Basal Metabolic Index. In 10 to 13 years age group, 60 were underweight and 7 had normal weight. As per Waterlows’s classification, all 211 children had normal weight for age. As per Gomez classification of children, in 6 -9 years age group, 52 and in 10-13 years age group 20 had normal nutritional status respectively whereas rest of the children fell in degree I and II malnutrition. Children and their parents need to be made aware about healthy nutritional practices.

Health Information Seeking Behaviour (HISB) refers to the ways in which individuals seek information about their health, risks, illnesses, and health-protective behaviours. According to a survey, the most common  topics of search included fitness and exercise, diet and nutrition, stress and anxiety, sexually transmitted diseases, puberty, depression and other mental health issues and sleep. The growth in the digital landscape and increase in health information has introduced a new trend among the young adults–seeking information from internet. Health Belief Model is one of the most important models in studying influences on health beliefs on both individuals and society. This is a study to identify media consumption patterns of young adults pertaining to health - the main areas of search, the platforms that are most commonly accessed, application of the information gathered and their existing health related values, attitudes and beliefs. Through a survey the study points out that although respondents are satisfied with health information consumed online, most of them however, do not find a positive change in health-related values and beliefs by consuming health information on media. There is a need for strong communication on health aspects.

Healthy people are always an asset to a nation. But with excessive hustle and bustle of today's life, people are inclined towards fast food and junk food. Following the elders, children also live with such foods that are satisfying their saliva. But such types of foods are harmful for health. If we can communicate the message properly to the students who are the future of the country, they will make a healthy nation. Following this, the researcher attempted to create awareness about healthy food choices among students. The study is descriptive in nature. The sample comprised of fifty-nine class VI students of a school in Bhubaneswar. Posters and pictures based on the theme of healthy eating were developed. Discussions on food and nutrition were a part of the assembly class. Data collected through a questionnaire were analyzed statistically and after interpretation it was found that posters worked as an effective tool to communicate the message needed to develop healthy food choices.

We are living in a world of innovations and growing scientific inquiry & literacy among all segments of the society. Online content has today become an inevitable part of our lives. In early childhood, science communication and scientific learning is essential for developing children’s early thinking process and future understanding, impacting skills of learning and attitude formation of a child. The social learning theory suggests that people learn from each other via observation and by imitating others. This paper inquires about how online videos are helpful in learning science and how it has changed the learning pattern in early childhood. The objective of this paper is to find out the importance of science learning through audio-visual learning techniques. This paper further explores the relevance of teaching and learning through online learning techniques. To achieve the objectives quantitative research approach has been adopted for data collection. The finding of this study revealed that teachers and parents of Delhi are in favour of science communication through online videos in early childhood learning for the overall development of a child and online teaching learning is the future of education. It should be adopted and encouraged in every educational setup.

Low literacy levels in developing countries is one of the reasons behind less rational thinking which hinders the development of scientific temper. If children are educated from the time they start to understand things, it may help them analyse the facts with validity. Games may be considered as a way to enrich communities with scientific temper since they are entertaining. Children could learn easily with calculations and puzzles than with the traditional math class. Today, the number of educational games in app stores is increasing each day. This study analyzes the different traditional games and digital games that communicate science and their balance between entertainment and scientific information.

Science magazines play a major role in the popularization of science among the public and creating scientific temper in the society. They act as a bridge between the scientific community and the society. Even though there are more than 50 science magazines published across the globe, very few have maintained consistency in publishing. Scientific American (started in 1845), Popular Science (1872), MIT Technology Review (1899) and American Scientist (1913) are very few that have been consistently published and have crossed the century mark. But these magazines are read mainly by the academic elite, and not by students or lay men. Publishing science magazines is not an attractive business as it is hard to find advertisements and subscriptions. This has affected many regional and national science magazines brought out by publishing houses and individuals. In the long run magazines have life only if they can maintain readership. In this era of digitization, science magazines should be made interactive with QR codes (Quick Response Code). Readers can scan the QR code using their smart phones and instantly view the contents of the magazine in a more interactive manner as videos or podcasts using web 4.0 technologies, which can be shared through social media platforms.

Newspapers are a great medium of science communication. They have the potential to popularise mathematics and its concepts, but often their coverage is limited to news and events about mathematics, results and phobia associated with mathematics rather than mathematical concepts. However, during the lockdown period in India (March-May 2020) few newspapers tried to expand their coverage to mathematical concepts. In coverage of COVID-19 news, mathematical and statistical concepts also found space in newspapers. The paper highlights these developments in the field of science communication through some news articles as examples.

J Scient Temp 2020, Vol 8(3&4), 146-60.

Science and Technology provide hands-on guidance in every field such as agriculture, medical sciences, health care, innovations, public utility services, internal and external security, education, entertainment; information and technology, etc. The awareness related to science through informing, educating, and sharing knowledge for promoting sustainable development is known as science communication. The basic aim of science popularization is to expose the society and upcoming generations to the virtues of scientific development and to help them understand the science in their daily life and surroundings as well. Motivating school children towards science is an important aim of science communication at the school level. The National Council for Science and Technology Communication (NCSTC), Department of Science and Technology (DST), Government of India, New Delhi has been organizing the “Children’s Science Congress (CSC)” as one of the mega flagship programmes at the block, district, state, and the national level throughout the country since the last 27 years. In the present paper, an attempt has been made to compile the experiences of three consecutive years (2017, 2018, and 2019) of Children’s Science Congress organized by the State Council for Science and Technology. It was categorized under seven themes in 2017, while two themes were merged in 2018 and 2019. A total of 11 districts of Uttarakhand participated in the 25th Children’s Science Congress during 2017, while in 2018 and 2019, all (thirteen) districts participated in the Children’s Science Congress. The total number of child scientists from different districts were found to be diverse – 107, 142, and 138 during the 25th, 26th and 27th Children’s Science Congress of Uttarakhand held in 2017, 2018 and 2019, respectively. In the present paper an attempt has been made to understand the impact of Children’s Science Congress (CSC) for creating scientific temper among child scientists and mentors.

J Scient Temp 2020, Vol 8(3&4), 119-34.

The world has witnessed many challenges, such as economic slump, catastrophes and pandemics. However, the global health pandemic, COVID-19, has created quite a stir. To address a global pandemic like COVID-19 requires a strong interlinkage of science and scientific communication as a tool for global health diplomacy with joint research activities; sharing of data on infection, laboratory, diagnostics and virology; knowledge exchange including best practices, etc. as a global public good. Science being objective and fact-based has played a unifying role in international relationships. It is even more evident during global health emergencies where science and its use as diplomatic communication tool have the potential to promote peace and healthy living for communities. In this perspective, it is essential to understand the soft power role of science communication and the autonomous role that science and scientists can play in international relations. Three cases have been analysed to explore the role of science and its effective communication as a tool for diplomatic persuasion and attraction using three classifications, namely: science directing foreign relations; science enabling international relations; and science advising policy-making. With learnings from the cases, the path ahead in the case of a pandemic like COVID-19 is projected with emphasis on 'Open Science Diplomacy' as a model for next-generation science communication and diplomacy in international relations.

Communication is important in science. It not only serves as a way to let people know about science but also helps in doing science itself, thus at times enabling learners and practitioners of science to know about the nature of science itself. In The Structure of Scientific Revolutions, Thomas Kuhn talks about ‘communication break’ during periods of scientific crisis. Often, even during periods of “normal science” (as used by Kuhn), communicating science is a challenge, while still keeping intact the intended meaning. The incommensurability of meaning may lead to a communication break. Such a situation leads to a deadlock and resolving such debates becomes very difficult. This also takes a toll on the communication of the general idea of science being debated to the students, general public and even other researchers. Using ‘Do genes encode information about phenotypic traits?’ a debate published in Contemporary Debates in Philosophy (ed. Hitchcock C. 2004), I try to look into how, even when both the debaters seem to understand the science correctly, do they reach at different conclusions in their debate. I also try to provide a solution to the debate, by looking at the relationship between the concepts being talked about in the debate. Resolving such debates is necessary as the science that forms the background of the debate is fairly old and robust and has made its way into textbooks and popular science journals long back. Thus, such debates may create negative perceptions among the students and general public, about the information being communicated to them in textbooks and popular science magazines, thus hindering further communication.

The communication of climate change from scientists, policy-makers and stakeholders to the public through the mass media has been a subject of interest in the research field. It is so because of its implications for creating public understanding of climate change and related issues. India is one of the major emerging economies, and so being one of the major greenhouse gas emitters, India is a key factor in the climate change story. On the other hand, USA one of the world's most developed and technologically advanced countries, has high energy consumption needs and therefore it is also one of the world's leading greenhouse gas emitters. Being politically strong at the world forum it holds an upper hand in global policy making about climate change issues. Hence it will be important to note how these two countries perceive climate change and subsequently sensitize, inform and interpret it through their mass media. In this study we analyse how climate change has been communicated through scientific frames in four major English dailies of India and USA.

Scholars have argued that science communication, like any other form of communication, is a socio-cultural process and should be considered as an interaction of two cultures. The thought structure of individual citizens, and thereby collectives, is shaped through socio-cultural processes (Raza, 2014). As scientific information, laws and theories generated in a far-removed scientific culture percolate and some of the ideas assimilate within the thought complex of the public fast, while others take longer time to get absorbed. This process is a complex function of factors, both extrinsic and intrinsic to the scientific information (Zhu X, 2017). In this article we present the shift in ‘relative cultural distance’ based on the analysis of data collected during Kumbh-1989, Ardh-kumbh-1995, Kumbh-2001, Ardh-Kumbh-2007, Kumbh-2013 and Ardh-kumbh-2019 at Allahabad over a period of thirty years. The present analysis has been conducted on five issues related to astronomy and cosmology section of the larger survey study, containing questions related to four areas of scientific knowledge, taking socialisation through education as the proxy-scale for cultural distance. It has been observed that there is a noticeable shift in the cultural distance between science and public. The mean cultural distance of astronomy and cosmology has progressively reduced in India.

Communication strategy and its application is a good means of creating awareness about a disease, its causes and treatments, change a person’s or group’s attitudes about a disease, advocate policy changes in favour of prevention and control, and create social norms that favour healthful living. A lot of emphasis has been given in the recent past to enhance the reach of Information, Education and Communication (IEC) activities on social and health issues. The crux remains to explore the quality and quantity of such activities in disseminating the information and making an impact on the masses. Although efforts have been made to address the health issues of Malaria, Tuberculosis (TB) and HIV/AIDS in India on a vigorous mode, no specific research paper on IEC activities addressing them has been developed or published after missing the Third Millennium Development Goal (MDG) in 2015. The gap is still evident, despite the fact that several health organizations like WHO, UNICEF, Public Health Foundation of India (PHFI), National Institute of Health and Family Welfare (NIHFW), Population Services International (PSI) among others have joined hands in executing the campaign to its full potential to overcome these diseases and achieve the Sustainable Development Goal (SDG) by 2030. It is noted that communication interventions hold a vital and indispensable place in prevention and treatment. Studies conducted in different countries, including Ethiopia, Mexico, Nigeria, Pakistan, Thailand and India revealed that patients with low knowledge about the symptoms of these diseases are more likely to delay the testing and treatment. And, there is a possibility of these patients visiting traditional healers and worsening the case. In all the programmes to overcome these diseases, the main content revolves around advocacy, behaviour change communication and social mobilization and IEC plays a vital role. Thus, the mission cannot be accomplished without any research papers on the IEC activities.This systematic review of literature identifies the gap, and aims at provoking more research papers to strengthen the IEC activities to overcome Malaria, TB and HIV/AIDS so as to achieve the United Nation’s Sustainable Development Goal by 2030.

Online teaching should continue at least as a supplement to classroom teaching to reinforce learning, or as an additional mode of teaching splitting the class. It should never replace the role of a classroom teacher. In the good number of present-day classrooms, the strength is more than 60. No more the strength could be maintained if the norm of ‘social distancing’ is in vogue. Students, in general, do not maintain social distancing on their own, and they normally view the formal education environment as an opportunity for socializing and physical closeness. However, there are challenges in online learning which will have to be overcome since this is the need of the hour.

In the diverse social structure that characterizes India, misbeliefs and superstitions are still as active as in earlier days. Social media in particular has been swamped by hundreds of beliefs and superstitions during the COVID-19 pandemic, primarily 'infecting' digitally literate people who are unable to check the fake and unthinkingly pass on suspect messages going viral. Common people in general have been found wanting in responding to calls for greater awareness and necessary behavioural change towards adopting safe practices. Mainstream media in India has been largely playing its role in educating people about the pandemic and thereby contributing towards inculcating scientific temper, but more needs to be done. Five highly circulated superstitions and misbeliefs on social media about the coronavirus have figured in this observation, while public awareness campaigns like 'hoax busters' by Indian Scientists' Response to Covid-19 (ASRC) and 'Infodemic vis-a-vis Pandemic' by Dr. Anamika Ray Memorial Trust (ARMT) have been highlighted as the sort of responses that can be mounted to counter misinformation and superstitions.

The expected rise of small devices in the Internet of Things (IoT) require these devices to operate without any power interruption. The replacement and recharging of batteries in these widely deployed small IoT devices is a challenging task. Recently, Ambient Backscatter Communications (AmB-Com) is introduced, which enables passive IoT devices to harvest power from nearby Radio Frequency (RF) signals. AmB-Com allows the passive devices to harvest energy and simultaneously transmit their information using the reflection of incident RF signals. This survey paper covers various types of ambient RF signals as the source of energy to energize passive IoT devices. Then, we show the utilization of multiple frequency bands to power up passive devices. In order to keep the balance between energy harvesting and information transfer, we discuss efficient power transfer schemes for AmB-Com in addition to energy management, resource allocation, and optimization techniques. Finally, we cover the performance of AmB-Com systems and highlight the research challenges in AmB-Com.

Principles of human-computer interaction (HCI) are imperative when it comes to efficient user interface design. This becomes even more significant when the interface is for users with special needs and especially when there is a treatment methodology incorporated in a piece of software. This study investigates user interfaces that are specifically made for children with autism-spectrum disorders. We conducted a survey to evaluate the adaptability and applicability of various interfaces. For this, we selected four of the behavioral interventions for autism namely discrete trial training (DTT), cognitive-behavioral therapy (CBT), empathy enhancement and verbal behavior approach (VBA). User interfaces (UIs) of 16 software applications were assessed for the said features. Results of this assessment revealed that these Applications were adaptable to two behavioral interventions, on the average. Moreover, these Applications were simultaneously applicable for treatment of three levels of autism; namely high functioning, low functioning, and autistic adults. These interfaces were also applicable to the children with no autism (typically developing) who acted as a controlled group.

Information and Communication Technology (ICT) infrastructure failure due to disasters result in huge monetary losses and jeopardize entire communication networks, directly affecting Public Protection and Disaster Relief (PPDR) operations. The absence of dedicated harmonized frequency bands for public safety and disaster relief communication is a major concern in India. It limits system functionalities and rescue efforts of Indian Public Protect and Disaster Relief (PPDR) agencies. In this paper, we conduct a survey of proposed and existing disaster management systems and emergency communication spectrum being used in developed countries, specifically Europe and the US and look at possible candidate frequency bands suitable for PPDR communication in the Indian scenario. We also look at global standards and regulatory frameworks drawn up by international standardization organizations for PPDR communication and spectrum allocation. We expand our scope of discussion by looking at ICT infrastructure currently being used in India to tackle large-scale PPDR operations. We further explore the possible system and design upgrades that may be carried out in future to support advanced early warning systems and state-of-the-art broadband PPDR networks.

Institutional Library resources both print and digital are of great help to both students and faculty members as an information source. However without proper knowledge of accessing the information sources from either electronic or print sources students are vulnerable to the overloaded information. This knowledge has been termed as data information literacy. In an attempt to introduce undergraduate students to data information literacy, a student project was initiated where participants got a structured introductory training on data retrieval. A survey was embarked upon to document some of the medicinal pteridophytes and gymnosperms present in Gurudas College campus. The students used the college library resources to access data on the phytochemicals present in those medicinal plants available in the college campus.

World Wide Web provides numerous opinionated data that can influence users. Reviews on online data highly affect the user’s perception while buying a particular or related product from an online shopping site. The online review provided by a customer helps other customers to make up their decision regarding purchasing that item. Looking at the developer’s and producer’s perspective, the opinions of customers on their manufactured items is helpful in identifying deformities as well as scope for improving its quality. Equipped with all this information, the product can be developed and managed more efficiently. Along with the overall rating of the product, the feature-based rating will have a great impact on the decision-making process of the customer. In this paper, an optimized scheme of aspect level sentiment analysis is presented to analyze the online reviews of a product. Reviews ratings have been used for learning approach. Inherently biased reviews are considered to optimize the Aspect Level Sentiment Analysis. Bi-polar aspect level sentiment analysis model has been trained using multiple kernels of support vector machine to optimize the results. Lexicon based aspect level sentiment analysis is performed first and later on the basis of bipolar words adjustment, and its effect on results, aspect level sentiment analysis for efficient optimization has been performed. A Web Crawler is developed to extract data from Amazon. The results obtained outperformed traditional lexicon based Aspect Level Sentiment Analysis.

In vehicular ad-hoc networks (VANETs), information dissemination plays vital role in establishing the cooperation among the vehicles. This cooperation and information exchange is needed for proper performance of safety and other VANET applications. Broadcasting is the most suitable method for information dissemination over the network. The simplicity of the broadcast mechanism in such a highly dense and mobile network leads to network contention, broadcast storm and network partition problem. To keep all nodes updated and gather neighbourhood information broadcasting protocol use beacon messages. A non-trivial scientific contribution is required in broadcasting techniques to cater to the need of a network. In this paper, we establish a system model and parameters responsible for efficient information dissemination for VANETs. We implemented three major techniques for information dissemination which are, simple flooding, counter-based and probability-based techniques. These three techniques are simulated with established parameters. The work also analysed the impact of beaconing in the network. The simulation is carried out on Veins framework and the results are then analysed on the basis of established parameters. The analysis of result shows that an integrated approach will suit the needs whereas the use of independent techniques might not yield the result which we expect. The paper concludes by outlining the future research directions in information dissemination in VANET.

The present technology offers online resources and open source software that enable researchers to explore built environment characteristics with health and allied phenomena. This article intends to delineate methods to capture available and accessible objective built environment variables for a state in India and determine their distribution across the state.  Built environment variables such as population density and residential density were collated from the Census of India. Safety from crime and traffic were captured as crime rates and pedestrian accident rates, respectively, acquired from State Crime Records Bureau. Greenness, built‑up density,and land slope were gathered from open‑source satellite imagery repository. Road intersection density was derived from Open Street Map. Processing and analysis differed for each dataset depending on its source and nature. Each variable showed a distinct pattern acrossthe state. Population and residential density were found to be closely related to each other across both districts and sub districts. They were both positively related to crime rates, pedestrian accident rates, built‑up density, and intersection density, whereas negatively related to land slope and greenness across the subdistricts.  Delineating the distribution of built environment variables using available and open‑source data in resource‑poor settings is a first in public health research among LMICs. Cost‑effectiveness and reproducible nature of open‑source solutions could equip researchers in resource‑poor settings to identify built environment characteristics and patterns across regions.

Ind J Pub Health 2020, 64(2), 186-90.

Alcohol increases risk of cancer of oral cavity and pharynx, esophagus, colorectal, liver, larynx, and female breast. The objective of this study was to determine the relationship of alcohol and cancer in India by meta‑analysis. Systematic Medline searches were performed to identify all the published literature associating alcohol and cancer in India. Initially, we retrieved 1509 studies, but after applying inclusion and exclusion criteria, only 29 studies were found eligible for our meta‑analysis. Our meta‑analysis shows that alcohol consumption increases the risk of cancer with the odds ratio (OR) of 2.32 (95 % confidence interval [CI]:1.50–3.47) in case–control studies and relative risk of 1.52 (95 % CI: 0.97–2.51) in cohort studies. It also shows that risk of oral cavity cancer increases by two times (OR: 1.92, 95 % CI: 1.54–3.96) in the population consuming alcohol. Publication analysis showed that studies included in the meta‑analysis had wide variation, suggesting good representation all over the country. The result from our meta‑analysis supports our hypothesis that alcohol consumption increases the risk of cancer, implying immediate cessation of the habit for cancer risk reduction.

Unplanned pregnancies are a major public health concern. In India, 33 % of an estimated 48.1 million pregnancies end in induced abortions. Emergency contraceptive pills (ECPs) can prevent pregnancy after sexual intercourse, have been part of India’s family planning program since 2002–2003 and are available as over‑the‑counter drugs. While there are concerns about the overuse of ECPs, the pattern of use of ECPs in India is unknown. The objective is to determine the proportion of women who have ever used ECPs and repeatedly used ECPs and also to assess the reasons for use and nonuse of EC pills along with factors associated with the use. A systematic review of ECP use in India was conducted by electronically searching three databases ‑ PubMed, Popline, and Google Scholar. All studies were published between 2001 and 2017, and the electronic search was last conducted in July 2018. The proportion of use was calculated using meta‑analysis, and the other factors were assessed by narratively synthesizing the findings. Thirty‑three articles met the inclusion criteria. The pooled proportion of women who ever used ECPs was 6 % (95 % confidence interval, 0.03–0.10). The proportion of repeat use ranged from 12 % to 69 %. Five studies reported reasons for not using ECPs, and the most common reasons were religious/cultural beliefs followed by fear of side effects and inadequate knowledge. Studies to understand socio demographic and other factors affecting the use of ECPs in India are lacking. There are significant concerns about the quality of the studies. The definition of repeat use of ECPs is inconsistent across papers. Further more, judgmental attitudes of health‑care providers were apparent in some papers. The review highlights important research and program gaps.

Ind J Pub Health 2020, 64(2), 161-7.

Nutrition epidemiology initially focused on few nutrients thought to be responsible for noncommunicable diseases (NCDs). The database of Indian Nutrition Survey is based majorly on calorie intake.  The objective was to compare the change in the average calorie intake from 1990 to 2012 with the emerging epidemic of diabetes and hypertension (HTN) in India since 1990.  A comprehensive search was made in National Library of Medicine’s PubMed database and Google Scholar from March to August 2018, on the above‑mentioned subjects. Reports of national surveys (National Sample Survey Office and National Nutrition Monitoring Bureau) were included for average calorie intake among different states from year 1990 onward. Region‑wise search depicted by national nutrition surveys resulted in 277 and 587 abstracts on the prevalence of HTN and diabetes mellitus, respectively. There were 51 full‑text articles and abstracts on the prevalence of HTN and diabetes from the above regions.  The average calorie intake per capita per day in the four zones of country in rural areas decreased from 1990 to 2012. An increasing trend in the prevalence of diabetes from rural areas was observed from 1994 to 2012. The percapita average calorie intake per day in urban areas from 1999 through 2011 in all zones except the eastern part of country was on rise. There was no consistent trend in the prevalence of HTN in any of the zones.  It is not just an increase in calories, but a trade‑off between the demand for calories and the demand for healthy lifestyles determines the prevalence of NCDs.

Ind J Pub Health 2020, 64(2), 109-15.

The geriatric depression scale – short form (GDS‑SF) considered an important preliminary screening tool, requires translation in different regional languages and validation, to become of utmost use in Indian context especially in the field level.  The current study aimed to evaluate the psychometric validity of the GDS‑SF translated into Bengali among rural elderly population. The 15‑item GDS‑SF translated to Bengali language was administered to 206 Bengali speaking geriatrics selected maintaining predecided inclusion and exclusion criteria from villages under a rural block in West Bengal. Latent trait modelling was used to evaluate the psychometric properties of this translated tool. Differential item functioning (DIF) was assessed to measure invariance. The mean age of the participants was 68.77 years (standard deviation 6.81 years). Majority being female (57.77 %), Hindu (87.38 %), from a joint family background (90.78 %). The highest discrimination was observed with item 8 (coefficient 3.682, P < 0.001) followed by item 14 (coefficient 3.020, P < 0.001). Question 2 had least coefficient for difficulty (−1.344, P = 0.013) while item 15 had highest (0.775, P = 0.001). The questionnaire provided maximum information (discrimination) around mean value of latent trait. The total cutoff score of 5 was related nearly to mean latent trait (−0.111). Items 10 and 13 showed consistent DIF across different demographic groups. Psychometric properties of GDS‑SF (Bengali) established overall construct and content validity of the tool in this community‑based study. Despite some degree of DIF the tool can be used as a preliminary screening method in rural community.

J Cont Med A Dent 2018, 6(2), 4-9.

The aim of this article is to investigate scientific literature with cases of vital teeth with radiographically visible intra-bony defects involving the apex and to evaluate current treatment options. This was a literature review of MEDLINE and Cochrane with no time restrictions. Two reviewers performed the data extraction independently using data collection forms. Four clinical case-control studies were found eligible and were included in the literature review. There are three possible treatment options according to the analyzed studies: periodontal treatment after root canal treatment; periodontal treatment only; and extraction and tooth replacement with implant, tooth-supported bridges, or Maryland bridges. The outcomes in all published cases showed a significant improvement in the most parameters regardless of the chosen treatment method. The absence of an accurate method to define pulp vitality complicates treatment selection. Further clinical studies are required to investigate treatment options for vital teeth affected by endo-perio pathology with intrabony defects involving the apex.

Research on information communication technologies (ICT) for entrepreneurship development is burgeoning, yet our understanding of the use of ICT in support of grassroots innovation remains unclear. This paper examines the moderating role of the use of ICT on the relationship between grassroots innovation (GRI) and entrepreneurial success (ES). The study involved 400 grassroots entrepreneurs selected from three states in India, and the moderating effect of the use of ICT was analysed using moderated structural equation modelling. The results revealed that the use of ICT partially moderates the relationship between the new learning practices and economic benefits. It also partially moderates the relationship between local solution and economic benefits, but it fully moderates the relationship between networking capabilities and economic benefits, where the relationship is stronger when the use of ICT is high. Furthermore, the study found that the use of ICT does not moderate the relationship between new learning practice and non-economic benefits, relationship between local solution and non-economic benefits and relationship between networking capabilities and non-economic benefits.

Genetic diseases are diverse and many of which have debilitating consequences affecting the individual, the society, and the economy. Trends databases, including Google Trends database, can be used to estimate the digital epidemiology of these diseases. Digital Epidemiology is valuable when it comes to conditions of low prevalence as in the case of ciliopathies including that of Meckel–Gruber Syndrome. To assess the digital epidemiology and the geographic mapping of Meckel- Gruber syndrome via a trends database of the surface web. Google Trends database will be usedfor geographic mapping and retrospective analysis of interest of users of the Surface Web. The aim is to infer and predict the digital epidemiology of Meckel–Gruber Syndrome. A retrospective analysis is conducted as far as the trends database permits (2004-2017). The trends database was explored using the thematic expression of keywords specific to Meckel–Gruber Syndrome including its synonyms. Subsequently, descriptive and inferential statistics were carried out to estimate the digital epidemiology as well as the geographic mapping. The aim was to conclude the existence of any significant change in web users’ interest and the variation of that interest versus geography (country) and chronology (time). Concerning geographic mapping, signals of web users were found to be originating from the United States (68.49 %) and Finland (31.51 %). Globally, the average value of the relative interest of surface web users in Meckel–Gruber Syndrome was 34.10 (+/- 14.59). There was an overall decline in web users’ attention towards the condition for the period 2004−2010 versus 2011−2017 (20.06 vs 4.88, p-value<0.001) and for period 2004-2006 versus 2007-2009 (29.14 vs 14.19, p=0.001). Digital epidemiological analysis has been proven feasible with good accuracy via Googles Trends. In the case of Dysencephalia Splanchnocystica, the geographic mapping of the surface web has been limited to the developed world. Prospectively, Google Trends can be integrated into a predictive early warning system to anticipate any change in the interest of the users of the Indexed Web in a particular disease including genetic ones.

The Medical Council of India came out with the criteria of research publications for the promotions for the first time in 2009. Though this was done with the intention of promoting and encouraging research among faculties of Medical Colleges, this has given rise to the genesis as well as mushrooming of predatory journals. Hence MCI has been making attempts to refine the criteria of publications and make the criteria more stringent. The last such attempt was in its PG committee meeting in January 2018 where it decided to constitute a committee of experts in each subject to draw a list of standard journals in their respective subjects so that publications only in these journals would be considered for future promotions. In this context, this article makes an attempt to assist researchers and regulatory bodies in assessing the quality of journals by means of a score-sheet.

This study describes the level of readiness, relevance and resources of the DepEd teachers as personally perceived and as observed by the school heads. This study is conducted to formulate an emergent theory which could be helpful in providing interventions and improving the teachers’ competencies in providing the desired 21^st century education. The study was conducted in the school year 2017-2018 and validated in the school year 2018-2019 in DepEd Danao City. A research made questionnaires were utilized in collecting the data, validated by interview of the randomly selected research participants. The result showed that the teachers are highly ready and relevant towards becoming educational change agents, yet they are struggling to be the functional resources. It is also proven that the school readiness, relevance and resources are major indicators for the teachers to reach their full potentials as change agents. It is theorized that 21^st Century school resources and professionally developed teachers create a 21^st century ready, relevant, and resourceful Department of Education in the Philippines. It is recommended that the school will provide training to improve the teachers’ competence and support the teachers with sufficient 21^st century resources.

In this study, we demonstrate a collective collaborative, conversational, pre-publication peer review of a randomized controlled trial. Using Critical Appraisal Skills Programme checklist, a group of research-oriented undergraduate medical and pharmacy students and their teacher collectively on an online forum, discuss and review a randomized controlled trial submitted to the Annals of Neurosciences and the explanatory commentary from each reviewer makes a basic scaffold for critical appraisal of the manuscript. This method provided the opportunity for students to engage in online interactive training and allowed them to understand tools used for critical appraisal of a study. Students were incentivized by the potential publication credit and they look forward to continuing this workand perhaps providing one small step to making medical education more interactive. Open peer review involving a group of reviewers at a time produces multidirectional reviewing concepts, thus helps to improve the quality of paper and also may reduce the time between review and publication.

In India, integrated biological and behavioral surveillance was carried out in 2014–2015 among high-risk key population as a part of second-generation HIV surveillance system. Computer-assisted personal interviewing and integrated information management system were used for the first time in this large national field based survey. We evaluated the strengths and weaknesses of technology use in this survey. Mixed methods comprising of the key informant’s interviews and structured data collected from field interviewers were used to do the strengths, weaknesses, opportunities, and threats analysis with defined attributes. Despite the challenges, the technology use in this survey was a huge success with respect to data coverage, response rates, real-time data, and acceptance by respondents. However, such techniques require more focus on the competency of human resource, training, and concurrent evaluation systems to get better data quality, time adherence, and effective use of technology. The recommendations resulted from this analysis will help for strategic management while designing such systems in field‑based community surveys.

The advancement of medical knowledge is quint-essentially based on the authentic and reliable scientific research and publications. This is in addition to the recently mandated requirement of original research publications in indexed journals to ensure career progression in academic/medical institutions, thus the need for 'publications' in scientific medical scholarly journals has increased substantially. On the other hand, this has given an unparalleled rise in the number of stand alone journals and publishers “Predatory” is the term, who are ready to process the manuscripts on priority with almost guaranteed publication, at a cost, but having no credibility to the research being published. To foster awareness creation among students at the post-graduate level and for faculty of medical colleges and research institutions, it has become very important to avoid these predatory journals. It is high time that the thinking among researchers of 'Publish or Perish' be changed to 'Publish and Flourish' by adopting stringent measures which have evolved over time to curtail this birch of predatory publishing. Researchers should now take the road less travelled. This review article aims to highlight all the relevant and important points about the threats posed by predatory journals and also suggests possible ways to overcome them.

This paper discusses teenagers’ need of library resources and library services in the public libraries in Iran. Descriptive method is used and a researcher-made questionnaire formed the major instrument for data gathering. Descriptive and inferential statistics are applied. It found that teenagers’ need is more textbooks than other resources, of course their first priority is educational books. It means that the teenagers interest to educational books, but it wasn’t their main need. Most used library services was familiarity to library while adolescents need to expand and improve lending services. Finally, it was concluded that libraries were less successful in meeting the teenagers’ need based on their priorities. Therefore, libraries need to be equally important in the development of their resources and services based on the priorities and needs. In this way, their needs are answered, and according to their priority, the library will answer their leisure time according to teenagers’ interest.

Nowadays, mobile technology seems to become integral part of our life. People with different careers have begun to use it in their jobs. This research aims to identify influential factors in mobile technology adoption at library context. To this end, a conceptual model was presented based on an integrated model of technology acceptance model (TAM) and technology organisation and environment (TOE) model. A researcher-made questionnaire was distributed among 120 academic librarians. Seven Factor out of the integrated model of TAM and TOE were chosen to investigate their influence on mobile technology adoption. The results of the study suggest that the proposed model (integrated model of TAM and TOE) is a favourable one to identify the influential factors in mobile technology adoption at library context. In addition, regression analysis indicated that out of these seven factor, perceived ease of use, perceived usefulness, compatibility, relative advantage and organisational competency are determinant factors in adopting mobile technology-based library services among academic librarians.

Dengue is currently regarded globally as the most important mosquito-borne viral disease. The true impact of dengue globally is difficult to ascertain due to factors such as inadequate disease surveillance, misdiagnosis, and low levels of reporting. Currently available data likely grossly underestimates the social, economic, and disease burden. Estimates of the global incidence of dengue infections per year have ranged between 50 million and 200 million, there are about 6,031 research paper collectively contributed by 22,234 scientist published in 6007 scientific periodicals in recent 8 years as the focus on this fever attracts attention of Scientists at the considerable rate. The present paper attempts to check the applicability of Lotka’s Law on the global publication on Dengue. The study lights on Lotka’s empirical law of scientific productivity, i.e., Inverse Square Law, to measure the scientific productivity of authors, to test Lotka’s Exponent value and the K.S test for the fitness of Lotka’s Law.

Scientometric analysis of 200 research article published in the journal, “Metamorphosis: A Journal of Management Research” from its debut year 2002 to 2016 is studied. The study focuses on various aspects of the journal such as the distribution of articles, annual growth rate, authorship pattern, authorship productivity, degree of collaboration, collaborative index, country-wise distribution of articles, citation analysis. The study shows that most of the papers, 114 out of 200 (57per cent) were published by single authors whereas 86 out of 200 (43 per cent) were contributed by joint authors. Overall average degree of collaboration, average collaborative index and average citation per paper were 0.43, 2.35, and 25.59, respectively. Remarkable collaborative contributors are from India with 81.65 per cent sharing. The study may help those who wish to map the scientometric patterns of journals or institutions or an individual.

The study makes an endeavor to assess the search interfaces of leading academic databases, viz Cambridge Journals, JSTOR, Sage Journals, ScienceDirect, SpringerLink, Taylor & Francis, and Wiley Online Library. The purpose of the study is to identify various search features and subsequently determine their relative location, with a view to recommend ideal location of these features based on their utility and users’ ease of mind. Data is harvested by assessing the search interfaces of seven academic databases subscribed by University of Kashmir. The select databases are individually assessed to harvest the required information. The study divulges that uniformity is observed by databases while positioning features like access points, and search box(s). However, no consistent approach is found while positioning other identified features. It is imperative to say that the study is first of its kind where an emphasis is laid on assessing the positioning of search interface features. The study can prove helpful for academic database designers while designing user-friendly academic databases.
