To examine the relationship between bullying and other forms of peer victimization in adolescence and alcohol use or misuse, all the pertinent studies were reviewed. Fourteen databases were searched. Blind assessments of study eligibility and quality were performed by two independent researchers. Seventy-four studies including 2,066,131 participants across 56 countries all over the world and meeting minimum quality criteria that were enough to ensure objectivity and to not invalidate results were analyzed. Across studies, evidence for a significant association between peer victimization and alcohol use or misuse was conflicting. Results were affected by sample size, definition of victim status, specific forms of peer victimization, and specific types of alcohol consumption. There was some evidence for a number of mediating or moderating variables, such as depression, coping, drinking motives, attachment to school, social support, and gender. Findings are discussed according to stress-coping and self-medication hypotheses. Alternative etiological mechanisms are also considered.

At least since Akerlof (1970), asymmetric information in the case of experience goods has been a central issue in the economic literature. This paper studies regulation in markets where the quality of the experience good is never completely verifiable by consumers even after purchase. In the proposed model firms can decide the quality of the good: always producing a high quality good creates a positive externality in the market, but it causes an incentive to the firms to deviate and produce low quality goods. The main policy instrument for the government, in order to maximize Social Welfare, is to fix a minimum quality standard, but imposing a too high standard might, in some cases, lower the average quality of the good in the market.

Sandcrete block is a vital building material used in the construction of building structures. The sandcrete blocks are produced by different manufacturers using river sand obtained from different locations as aggregate material without recourse to the minimum quality standard for the blocks produced. The study assessed the strength parameters of river sand used as an aggregate material in block production to determine its quality and suitability in relation to the strength of block produced. Three (3) block manufacturing sites in Nigeria were visited and 27 (twenty-seven) blocks of size 450 mm x 225 mm x 225 mm were selected randomly from the sites. The properties of the river sand was analyzed through sieve analyses, bulk density, silt content and water absorption while the compressive strength of the blocks was also tested. The result of sieve analysis of the river sand used in block production for this study all satisfied the particle size requirements of BS EN 933-1:1997 for general construction work including block production. The result of the study also shows that blocks produced with the river sand after 28days have an average compressive strength of 1.23 N/mm2 (SW), 1.54 N/mm2 (SE) and 1.95N/mm2 (NE). The study, therefore, concluded and recommended that regulatory and professional bodies in partnership with relevant associations should organize seminars for producers of sandcrete blocks on the best practices involved in producing quality sandcrete blocks.

This article presents the results of an exploratory-descriptive research with empirical referents. The objective was to document, systematize and evaluate some features of 15 postgraduate theses in education, with the intention to make visible some recurring dishonest practices of students and teachers. The postgraduate programs from which the theses were obtained are located in the metropolitan area of Mexico City. The selection of documents was carried out between July and November 2015. Two Likert scales were used to assess two dimensions separately: 1) content, in which originality, congruence, dominance and relevance of authors, findings and relevant conclusions were considered; and 2) presentation, which examined style, logical structure, spelling and punctuation, citations, references and sources of information. Each indicator was assigned a numerical value and this one was given an evaluative characteristic: 5: excellent, 3: regular and 1: deficient. Subsequently, percentages were obtained. The results indicated that only a third of the theses could be classified as excellent for the quality of the content and the impeccable presentation; a similar percentage were works that fulfilled the necessary but didn’t count with the rigor and originality of the first ones. The remaining papers had serious deficiencies, both in content and in the formal presentation of the document, without achieving the minimum quality demanded by a postgraduate thesis. The analysis of these investigations made it possible to visualize some of the dishonest practices of people graduating from various educational programs and the lack of commitment to their research. The results about the quality of the research in various doctoral programs indicate that there is little responsibility in students, personal tutor and the reviewer. The results allow the authorities of each program to observe the problem and seek practical solutions to solve it.

For several years, the Democratic Republic of Congo has been the scene of strikes by the country’s doctors. The strikers’ demands are essentially financial and statutory and are intended to put pressure on the government. In this country, as is the case almost everywhere in the world, medical strikes are allowed. Every worker has the right to denounce by strike working conditions that are considered unacceptable. But are doctors just like any other workers? Do they not have particular moral obligations linked to the specificities of their profession? To shed light on these questions, the authors of this article propose three essential moral benchmarks that can be generalized to medical strike situations elsewhere in the world. The first concerns the recognition of the right to strike for doctors, including for strictly financial reasons. Health professionals cannot be asked to work in inhuman working conditions or without a salary to support their families. The second benchmark argues that it is unacceptable for this right to strike to be exercised if it sacrifices the most vulnerable patients and thus denies the very essence of the medical profession. A third benchmark complicates the reflection by reminding us that the extreme dilapidation of the Congolese health system makes it impossible to organise a minimum quality service in the event of a strike. To overcome these difficulties, we propose a national therapeutic alliance between doctors and citizens to put patients back at the centre of the health system’s concerns.
