Methods: Campaign impact was measured in representative cross-sectional household surveys of adults ages 18 to 55. A baseline survey was conducted before the launch of the campaign (n = 1430). Evaluation surveys were conducted mid-campaign (n = 1571) and post-campaign (n = 1500). Campaign impact was assessed by comparing changes across survey periods on key knowledge, attitudinal and policy support outcome indicators. The independent association between campaign awareness and outcomes was analyzed using logistic regression analyses. Results: The campaign was recalled by more than 80% of respondents and was well-received with 90% or more respo...

This unique bacteriophage character is highly beneficial because it is harmless to mammalian cells and does not interfere with natural microbes. Bacteriophages are easy to obtain because they are widespread in the environment such as soil, water, animal, and farm waste or food. This paper describes the potential use of bacteriophages to detect pathogen and foodborne pathogen biocontrol. Bacteriophages are very potential to control the growth of pathogenic bacteria both in food industry and environment. Bacteriophages act as antibiotics, detection tool for pathogenic bacteria in the food chain, food biopreservative from pathogen bacteria contamination, and foodborne disease prevention. Although research on bacteriophage in Indonesia has not been widely reported, research on bacteriophage utilization is being carried on.

Due to dearth of literature, the study could not focus beyond 1891 and restricted the period of study till 1931. The sole dependence while writing the paper has been on available census reports from which insights could be drawn about the process of internal migration in India. It has been found that Bengal, Assam and Bombay were the main centres of immigration and United Provinces, Mysore, Bihar and Orissa had been centres of emigration. Though the pattern of internal migration remained quite similar between 1891 and 1921, in 1931 some new centres of immigration came up e.g. Delhi, Bikaner etc. Apart from this, a gradual change has started taking place in the pattern of internal migration in India.

This reconstruction theorem is compatible with symmetric monoidal structures, and with more general operadic structures such as En-monoidal structures. We also provide a suite of fundamental operations for constructing new stratifications from old ones: restriction, pullback, quotient, pushforward, and refinement. Moreover, we establish a dual form of reconstruction; this is closely related to Verdier duality and reflection functors, and gives a categorification of Möbius inversion. Our main application is to equivariant stable homotopy theory: for any compact Lie group G, we give a symmetric monoidal stratification of genuine G-spectra. In the case that G is finite, this expresses genuine G-spectra in terms of their geometric fixedpoints (as homotopy-equivariant spectra) and gluing data therebetween (which are given by proper Tate constructions). We also prove an adelic reconstruction theorem; this applies not just to ordinary schemes but in the more general context of tensor-triangular geometry, where we obtain a symmetric monoidal stratification over the Balmer spectrum. We discuss the particular example of chromatic homotopy theory. 2.6. The microcosm and nanocosm morphisms 2.7. Strict objects 3. Fundamental operations 3.1. Alignment 3.2.

Lax limits References 8 This is closely related to its adelic stratification, which is described in Example 4.6.13. 9 This particular example can be seen as a consequence of Greenlees-May duality (or even of local duality for Spec(Z)). 10 We write M tors p := fib(M → M ⊗ Z Z[p −1 ]) for the p-torsionification of M , in analogy with the notation M ∧ p for its p-completion. More generally, we use the notation X ↓ Y to denote a morphism in any ∞-category C that we consider as defining an object in the overcategory C /Y. (3) Given some datum in an ∞-category (such as an object or morphism), for clarity we may use the superscript (−) • to denote the corresponding datum in the opposite ∞-category. (4) Given a functor F , we write F * for pullback along it, and we respectively write F ! and F * for left and right Kan extension along it. (5) We write Cat for the ∞-category of ∞-categories, S for the ∞-category of spaces, and Sp for the ∞-category of spectra. These are related by the various adjoint functors

The first of its kind, this study unearths, through detailed regional and demographical research, the ways in which economic and migratory trends of male family members in rural India in general, and hilly regions of Garhwal in particular, affect the wives, children, extended families, and agricultural lands that they have left behind. It offers vital research in how rural India’s socio-economic formations and topographic characteristics can today more effectively contribute to the national and global economy with respect to migratory trends, gender dynamics, and home life. Furthermore, it investigates the collapse of agricultural and many other traditional economic activities without a corresponding creation of fresh economic opportunities.

These should report original research findings within the journal's scope. Papers should generally be a maximum of 4000 words in length, excluding tables, references, abstract and key points of the article, whilst references should not exceed 36. Review Papers Comprehensive, authoritative, reviews within the journal's scope. Review articles provide a review of the literature. There are two types of review papers:-systematic review papers: respond to a specific research question, accrue from criterion-based selection of sources, include a quantitative synthesis that includes a statistical method (meta-analysis) and should adhere to PRISMA guidelines. Guidelines used for abstracting data and assessing data quality and validity should be noted in methods section.-narrative reviews: the research question may be broad, and the scope of this review is to discuss a specific topic and keep the readers up-to-date about it. This type of review does not necessarily include a methodological approach and its synthesis is usually qualitative. Narrative reviews should include a "developments" section, with details regarding data sources used, keywords applied, time restrictions and study types selected. All review papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50 unless on a topic that has an extensive evidence base. The conclusion of the reviews must be specific and stem from the findings. Short Reports Brief reports of data from original research. Short reports are shorter versions of original articles, may include one table or figure, should not exceed 1500 words and 15 references. Short reports are suitable for the presentation of research that extends previously published research, including the reporting of additional evidence and confirmatory results in other settings, as well as negative results. Authors must clearly acknowledge any work upon which they are building, both published and unpublished. Study Protocols Articles describing a research protocol of a study. This article type can be for proposed or for ongoing research and should contain the background, research hypothesis, rationale a detailed methodology of the study. The SPIRIT 2013 Checklist guidelines ideally should be applied. Study protocols submitted for publication must have received ethics approval. Protocols of randomized trials should follow the CONSORT guidelines and must have a trial registration number, while observational studies should follow STROBE guidelines. Methodology Papers Papers that present different methodological approaches that can be used to investigate problems in a relevant scientific field and to encourage innovation. It is suggested that case studies or practical examples, which can be existing ones, are included to demonstrate the consistency and applicability of the methodology. Methodology papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50. Letters to the Editor A letter to the Editor is a brief report that is within the journal's scope and of particular interest to the community, but not suitable as a standard research article or as a short report. Letters to the editor may also report original research data, if the sample size is small. A maximum of ten articles may be included in the references. Letters intended for publication should be a maximum of 500 words, contain 10 references, and up to one table or figure. These rules apply both for research letters, and letters that respond to articles published in the journal. Letters to the editor are subject to editorial editing so as to streamline with the journal's style. Editorials Editorials are written by members of the Editorial Board or by invited topic experts and may reflect current articles within TID

This book moreover elucidates how male out-migration from rural to urban centres has greatly re-shaped kinship and economic structures at places of origin and has consequently had a serious impact on the socio-psychological well-being of family members. This book will be of great value to scholars and researchers of development economics, agricultural economics, environment studies, sociology, social anthropology, population studies, gender and women’s studies, social psychology, migration and diaspora studies, South Asian studies and behavioral studies

Media coverage of air pollution issues plays an important role in influencing public opinion and increasing citizen demand for action on clean air policy. Hence, this study was designed to assess news coverage of air pollution in India and its implications for policy advancement. Methods Articles published online between 1 January 2014 and 31 October 2015 that discussed air pollution in India were systematically content analysed. From 6435 articles in the national media and 271 articles in the international media, a random selection of 500 articles (400 from national and 100 from international media) were analysed and coded by two independent coders, after high inter-rater reliability (kappa statistic above 0.8) was established. Results There was an increase in the number of news stories on air pollution in India in the national media over the study period; 317 (63%) stories described the risk to health from air pollution as moderately to extremely severe, and 393 (79%) stories described the situation as needing urgent action. Limited information was provided on the kinds of illnesses that can result from exposure. Less than 30% of stories in either media specifically mentioned the common illnesses resulting from air pollution. Very few articles in either media mentioned the population groups most at risk from air pollution, such as children or older people. Vehicles were presented most often as the cause of air pollution in India (in over 50% of articles in both national and international media). Some of the most important sources of air pollution were mentioned less often: 6% of national and 18% of international media articles mentioned unclean sources of household energy; 3% of national and 9% of international media articles mentioned agricultural field burning. Finally, the majority of articles (405; 81%) did not mention any specific institution or organization-such as the government or industry groups-as the primary responsible stakeholder, thus leaving ambiguous the organizations whose leadership was necessary to mitigate air pollution. Conclusion Gaps exist in the current media discourse on air pollution, suggesting the need for strengthening engagement with the media as a means of creating citizen engagement and enabling policy action. Through greater elaboration of the health burdens and evidence-based policy actions, the media can play a critical role in galvanizing India's action on air quality. These data may suggest opportunities for media advocacy and greater public and policy engagement to address issues around air quality in India.

Driving under the influence of alcohol (drink driving) is a risk factor for road traffic crashes. Mass media campaigns can reduce the prevalence of drink driving. Few studies to date have evaluated the influence of anti-drink-driving campaigns on changes in knowledge, attitudes, and behaviors in low-income countries such as Ethiopia.Objective: This study aims to examine the impact of an anti-drink-driving campaign on knowledge, attitudes, and behaviors around drinking and driving in Addis Ababa, Ethiopia.Methods: The “Never Drink and Drive” campaign ran on media outlets in Addis Ababa and consisted of evidence-informed messages on the consequences of drink driving. Data for this study comes from two representative household surveys conducted among a sample of adult drivers aged 18–55 years in Addis Ababa pre-campaign (n = 721) and post-campaign (n = 721). Multivariate logistic regre...
