In the course of development of human communities towards industrially advanced societies of today, there have been changes not only in economic conditions in the majority of fields of human activity but also in the ways of providing for food, which went hand in hand with changes in living conditions. Large‐scale industrial production has brought about major changes in the way of life of the population. The development of industrial agglomerations results in a growing number of city dwellers, most of whom have no chance of producing foodstuffs of their own in kind. The distance between residential and industrial areas has been growing, the number of employed women has risen considerably. These are but a few factors affecting the way of boarding, particularly in households.

THE London and Home Counties Branch is fortunate in having close at hand watering places which can house its Autumn or other Conferences conveniently. Hove in fair weather in October is a place of considerable charm; it has many varieties of hotel, from the very expensive to the modest; it is used to conferences and the hospitality of the Town Hall is widely known. This year's conference was focused in the main on problems of book‐selection which, as one writer truly says, is the main purpose of the librarian because all his possibilities hang upon it. The papers read are valuable because they appear to be quite unvarnished accounts of the individual practice of their writers. Of its kind that of Mr. Frank M. Gardner is a model and a careful study of it by the library worker who is in actual contact with the public might be useful. For his methods the paper must be read; they are a clever up‐to‐minute expansion of those laid down in Brown's Manual with several local checks and variations. Their defects are explained most usefully; there is no examination of actual books before purchase and bookshops are not visited, both of which defects are due to the absence in Luton of well‐stocked bookshops; a defect which many sizeable towns share. We find this remark significant: “The librarian of Luton in 1911 had a book‐fund of £280 a year for 30,000 people. I have nearly £9,000 for 110,000. But the Librarian in 1911 was a better book‐selector than we are. He had to be, to give a library service at all. Every possible purchase had to be looked at, every doubt eliminated.” We deprecate the word “better”; in 1911 book‐selection was not always well done, but Brown's methods could be carried out if it was thought expedient to do the work as well as it could be done. The modern librarian and his employers seem to have determined that the whole of the people shall be served by the library; that books shall be made available hot from the press, with as few exclusions as possible. No librarian willingly buys rubbish; but only in the largest libraries can a completely comprehensive selection practice be maintained. Few librarians can be quite satisfied to acquire their books from lists made by other people although they may use them for suggestions. How difficult is the problem Mr. Gardner demonstrates in connexion with books on Bridge; a shelf of apparently authoritative books might possibly contain not one that actually met the conditions of today. If this could be so in one very small subject, what might be the condition of a collection covering, or intended to cover, all subjects? Librarians have to be realists; orthodox methods do not always avail to deal with the cataract of modern books; but gradually, by cooperative methods, mechanical aids and an ever‐increasing staff devoted to this, the principal library job, much more may be done than is now possible.

The purpose of this study was to optimize the parameters for enhancing the vitamin D₂ formation in three edible mushroom varieties, namely, shiitake mushroom (Lentinula edodes), white button mushroom (Agaricus bisporus) and oyster mushroom (Pleurotus ostreatus) using ultraviolet (UV) irradiation.

Freshly harvested mushrooms were irradiated with UV-B and UV-C lamps. Further, mushrooms were treated with UV-B at a distance ranging between 10 and 50 cm from the UV light source, for 15–150 min, to maximize the conversion of ergosterol to vitamin D₂. Analysis of vitamin D₂ content in mushrooms before and after UV exposure was done by high pressure liquid chromatography (HPLC).

HPLC results showed a significant (p < 0.001) increase in vitamin D₂ levels of shiitake (17.3 ± 0.35 µg/g), button (24.9 ± 0.71 µg/g) and oyster (19.1 ± 0.35 µg/g) mushrooms, irradiated with UV-B at a distance of 20–30 cm for 120 min. Further, stability studies revealed that vitamin D₂ levels in UV-B-irradiated mushrooms gradually increased for 48 and 72 h of storage at room and refrigeration temperatures, respectively. During cooking operations, 62%–93% of vitamin D₂ was retained in UV-B-irradiated mushrooms.

This study describes the most effective parameters such as ideal wavelength, mushrooms size, duration of exposure and distance from UV sources for maximum vitamin D₂ formation in edible mushrooms using UV irradiation. Further, assessment of vitamin D₂ stability in UV exposed mushrooms during storage period and cooking operations has been carried out. In addition, this study also provides a comparison of the vitamin D₂ levels of the three widely cultivated and consumed mushroom varieties treated simultaneously under similar UV exposure conditions.

The hot dip galvanising process is a well‐established means of rust‐proofing iron and steel. In Western Europe 78,000 tons of zinc are used every year for galvanising sheet and strip. In the U.S.A., where galvanised sheet is widely used, the figure is 132,000 tons p.a. Galvanisers on both sides of the Atlantic can learn much from each other and last month about 200 experts from Britain, the Continent and America met at Oxford for an International Conference on Hot Dip Galvanising under the auspices of the Zinc Development Association. The subjects discussed ranged from the galvanising of wire to an incentive wages scheme for galvanising workers. Here are summaries of some outstanding papers.

The time dimension of a country is a key determinant of the time horizon prevalent in the business sector. The long‐term horizons of Japan compared with the short‐term horizons of the United States are integral parts of their distinct business ideologies. There is a direct impact on their respective financial practices. A comparative analysis of the financial management ideologies, practices and techniques, within the framework of time horizon, offers an explanation of Japan's inordinate economic success in the global market.

Intercollegiate athletics are a major investment of time for student-athletes who must balance their academic and athletic commitments. For African American males, sports participation may have adverse effects on both their educational outcomes and career development. According to the extant research base, the low academic achievement and high aspirations toward professional athletic careers for many African American males are due to a variety of factors including socialization toward athletics by family, community members, and the media. We posit that African American male student-athletes may prematurely settle on an athletic identity with limited or no exploration to other possible identities, namely career identities. Using an adaptation of Dawkins, Braddock II, and Celaya’s (2009) model of academic engagement, we categorize African American male student-athletes into three persona types; maintenance, incentive, and integrative. Maintenance and incentive persona types value academics as a necessary step toward an athletic career, whereas integrative persona type understands that academics and athletics can benefit a comprehensive career development.

This chapter describes a partnership model in which a university in the United States facilitated cultural exchanges between elementary students in US schools with students in international schools in Central and South America. Through the partnerships, faculty members at the university were able to facilitate opportunities for elementary students to communicate and share experiences through the use of virtual field trips (VFTs) and gardening projects. These exchanges were achieved through the use of multiple Web 2.0 tools that allowed interaction between students. They led to the engagement of students both locally and globally by providing them with a dynamic environment, in which they could explore, discover, experiment, and learn. Descriptions of the challenges faced, lessons learned, and recommendations for educators are also included.

Coating composition. A composition for use, e.g. in coating iron, etc., with a layer of metal with strong bonding consists of a low‐viscositysolution of chlorinated synthetic or natural rubber in an organic solvent mixed with a heavy metal powder (Pb, Ni) and including an osmic catalyst, e.g. potassium osmiate or osmic chloride, to the amount of 0.00025 to 0.001% of the total—Brit.

Corrosion is one of the chief factors contributing to the wear of the cylinders and piston rings of an automotive engine. It is caused by acids formed in the combustion process, particularly those resulting from the combination of certain gases with water condensed on the cylinder walls in low‐temperature operation. In this article the author discusses the mechanism of corrosive cylinder wear, together with the factors influencing it, and reviews some of the methods of mitigating the attack.

The purpose of this paper is to explore the relationship between psychopathic features as measured with the Psychopathy Checklist: Youth Version (PCL:YV) and behavioural and emotional functioning in young female offenders in custody.

This is a quantitative interview study investigating the relationship with psychopathic traits, measured with the PCL:YV (Forth et al., 2003), and different psychological characteristics as well as AD/HD, self-harm, and childhood trauma in adolescent offenders across genders. Data were collected from a sample of 40 female and 40 male adolescents who were incarcerated in Victoria, Australia.

Results indicated that the behavioural subscales of the PCL:YV were associated with externalising behaviours possibly underpinned by histories of abuse and substantiated child protection incidences. The presence of AD/HD was strongly associated with affective deficits suggesting that the PCL:YV may be identifying young females with AD/HD rather than core psychopathic traits. Findings also indicate that female-specific manifestations of manipulation are likely being misidentified as behavioural phenomena precluding clinical recognition as a core interpersonal trait. Significant dissimilarities with a young male comparison group were identified and are discussed within.

The sample size is very small and the results should be seen as an indication rather than generalising.

Studies on female juvenile offenders is rare and this study adds to the literature on the construct of psychopathy and its relationship to psychosocial factors as well as associations with AD/HD, self-harm, and childhood trauma, among incarcerated adolescents.
