Average intakes of vitamin B₆ are equal to, or greater than, reference nutrient intakes and clinical deficiency disease due to inadequate dietary intake is unknown. Although there is little scientific evidence of efficacy, the vitamin is widely recommended for treatment of premenstrual syndrome at levels of 50‐100mg/day (compared with reference nutrient intakes of under 2mg/day). At higher levels of intake (over 1,000mg/day), there is clear evidence of nerve damage, and there have been reports of symptoms of nerve damage in people taking between 50‐100mg/day.

This study investigates associations between Facebook (FB) conversations and self-reports of substance use among youth experiencing homelessness (YEH). YEH engage in high rates of substance use and are often difficult to reach, for both research and interventions. Social media sites provide rich digital trace data for observing the social context of YEH's health behaviors. The authors aim to investigate the feasibility of using these big data and text mining techniques as a supplement to self-report surveys in detecting and understanding YEH attitudes and engagement in substance use.

Participants took a self-report survey in addition to providing consent for researchers to download their Facebook feed data retrospectively. The authors collected survey responses from 92 participants and retrieved 33,204 textual Facebook conversations. The authors performed text mining analysis and statistical analysis including ANOVA and logistic regression to examine the relationship between YEH's Facebook conversations and their substance use.

Facebook posts of YEH have a moderately positive sentiment. YEH substance users and non-users differed in their Facebook posts regarding: (1) overall sentiment and (2) topics discussed. Logistic regressions show that more positive sentiment in a respondent's FB conversation suggests a lower likelihood of marijuana usage. On the other hand, discussing money-related topics in the conversation increases YEH's likelihood of marijuana use.

Digital trace data on social media sites represent a vast source of ecological data. This study demonstrates the feasibility of using such data from a hard-to-reach population to gain unique insights into YEH's health behaviors. The authors provide a text-mining-based toolkit for analyzing social media data for interpretation by experts from a variety of domains.

To examine how clinicians navigate providing treatment to Borderline Personality Disorder (BPD) in the context of the DSM 5, deinstitutionalization, and the biomedical model.

We conducted 39 interviews with mental health providers in the United States in a two-year period preceding and following the release of the DSM 5. Using Constructivist Grounded Theory, we analyzed the data for themes that emerged.

Clinicians faced pressures from insurance companies, the DSM categories, and their professional training to focus on biomedical treatments. These treatments, which emphasized pharmaceuticals and short courses of care, were ill-suited to BPD, which has a strong evidence base recommending long-term therapeutic interventions. We term this contradiction a “biomedical mismatch” and use Gidden’s concept of structuration to better understand how clinicians navigate the system of care. Providers ranged in their responses to the mismatch: some championed biomedicine, others were complicit, and a final group behaved as activists, challenging the paradigm. The sum of the strategies had downstream effects which included crisis reinstitutionalization and a discourse of untreatability. Ultimately, we discuss how social factors such as gender bias, stigma, and trauma are insufficiently represented in the biomedical model of care for BPD.

BPD fits poorly within the biomedical underpinnings of the current system. Accordingly, it illuminates the structuration of health care and where the rules of care break down. More precisely, deinstitutionalization was designed to remove patients from long courses of inpatient care. Many patients with BPD have failed to experience this outcome, with some patients now cycling through long courses of short-term crisis reinstitutionalization instead of having effective outpatient care over long periods. This unintended consequence of deinstitutionalization calls for a more biopsychosocial response to BPD.

In less developed countries there are chronic food shortages and scarcity of arable land and water, coupled with increasing population. Widespread irrigation permits more intensive agriculture, but fertility is decreased and outbreaks of fluorosis and arsenic poisoning have occurred. Use of modern fertilizers causes soil mineral deficiency, including that of zinc. Iodine deficiency has caused outbreaks of goitre. Increased fertilizer use leads to an unacceptably high concentration of nutrients and potential toxins in rivers and lakes. Industrial effluent also poses a serious problem.

This chapter begins by covering four parenting styles and their effects on college students’ wellbeing. Next, the effects of parents’ divorce and parental death on college students are explored. In addition to relationships with their parents, the chapter also examines college students’ relationships with their friends. Friendships based on utility or pleasure are contrasted with those based on virtue. Next, the chapter explores the effects of college students’ friendships on various aspects of their academic performance (e.g., dropping out of school) and social lives (e.g., drinking behaviors). The role of social media in college students’ relationships is considered as well. The chapter concludes with a focus on college students’ romantic relationships.

Self-help groups (SHGs) have widely been accepted by developing nations for their contribution to inclusive development. Despite its importance and the recognition of the same, SHGs and their members face several challenges. The purpose of this paper is to comprehensively investigate the inhibiting factors affecting the effectiveness of women SHGs. The paper also proposes a roadmap for all the self-help promoting institutions, such as banks, state and central government, and non-government organizations to address the challenges.

The study adopts an exploratory research design to undertake this applied research. It uses phenomenographic and interpretative approaches. Qualitative data have been collected from 24 members belonging to eight SHGs from the eastern Indian state of Odisha with the help of a semi-structured interview schedule. The result has been analyzed by using content analysis.

The study finds that SHG members in Odisha face several challenges in the form of financial bottlenecks, entrepreneurial obstacles, capacity-building impediments, mentor-ship challenges, socio-structural challenges and group dynamics.

The study finds many unique and contextual inhibiting factors, which are valuable additions to the existing literature. At the same time, the result may not be applicable to other kinds of SHGs, such as Alcoholic Anonymous, as their nature, composition and deliverables are quite different from the SHG that the current study has taken into consideration.

The proposed roadmap would be useful to policymakers, non-government organizations and other agencies involved in the promotion and capacity building of SHGs operating in Odisha in particular and India in general.

The literature is mainly concerned with the impact evaluation of SHG programs. This study investigates the challenges faced by SHGs in a systematic way and provides a roadmap to address the same in a comprehensive way.

Over the past few years the food industry has been criticised by the press for a massive list of problems, including allergies, irradiation, food poisoning and food additives. In this somewhat controversial article, the author considers just how far the industry is responsible for these “real or apparent” problems and what responsibility it has.

The large, all‐purpose local authorities established by the Local Government Re‐organization Act, 1972, for England and Wales—Scottish local government re‐organization is yet to be completed—are operative; members have long since been elected and organization and staffing, if not complete, at least ready to commence. It is certainly the greatest upheaval since urban and rural sanitary authorities were set up about the middle of the last century. The last change of any magnitude was in 1934; small, however, compared with 1974. At that time, there were 62 county councils, 83 county boroughs and nearly 300 municipal boroughs, 29 metropolitan boroughs, more than 600 urban and about 500 rural districts; roughly 1,600 local authorities. The tremendous reduction in authorities by the present re‐organization illustrates the extent of the upheaval.

The sale of irradiated food is currently prohibited in the United Kingdom under The Food (Control of Irradiation) Regulations 1967. This situation seems likely to change given first the recommendation by a number of expert committees that irradiated food is safe and wholesome, and second the current need to complete the EEC internal market for food in a situation where several member states already permit the sale of irradiated produce. The controversy surrounding the irradiated food issue is, in part, politically inspired. In particular, the issue has served to articulate concern over the lack of consumer representation in food policy decision making forums, both at the UK and European level. Consumer resistance to the technology for the most part, however, reflects an exaggeration of the perceived risks associated with buying and consuming irradiated foods, together with a negative evaluation of the benefits that the process offers. Consumers perceive these benefits as accruing mainly to the food industry. The difficulty that consumers have in believing that they, too, can share in these benefits stems from the way in which consumers make sense of the knowledge that they possess about food. It is this problem which needs to be addressed.
