Abstract
Purpose
The purpose of this paper is to direct attention to social and cultural leadership in the area of family matters as they relate to black and disadvantaged communities. It seeks to reject and qualify the prevailing notions of victim status attributed to such groups in debates around the family and crime, while highlighting and challenging the various rationalities of the key actors involved. The paper calls for greater responsibility from those who view themselves as disadvantaged, and others who seek to advocate on their behalf.
Design/methodology/approach
This paper is based on data gained from interviews carried out with black men, community activists, and participatory observation.
Findings
Black leaders for their own political motives continue to uncritically promote notions of female victimhood in the context of discussions around the family, youth delinquency, and crime. However, black lone‐parents are not passive victims and are often rational actors in the pursuit of personal goals, albeit often short‐sighted in terms of their social consequences.
Practical implications
More research is required especially reflecting black male perspectives about parenthood and lone‐parent families. Research is also called for on the issue of policing, crime prevention, and related strategies utilised by community activists in addressing the complex range of problems experienced by their communities. The paper calls for a stop to the practice of demonising black men in the context of debates around family matters, and the adoption of a more balanced approach to the issues in question.
Social implications
The paper contributes to a more informed debate on the topic, especially within affected communities, and discussions about parenting support/education, and the cultural specificity of some of the issues in question.
Originality/value
The paper highlights the role of black women's decision making in the context of family formation, and the role of sexism in black cultural practices in privileging female behaviour.

Abstract
Although issuers may benefit generally from securitization, some asset securitizations transfer more credit risk than others. When a lender uses securitization to replace on‐balance‐sheet financing, that lender transfers to investors some of the risks, and, in the form of credit enhancements, some of the offsetting, i.e., claims‐paying, economic resources (e.g., assets, cashflows), as well. Therefore, securitization only reduces an issuer's net (i.e., residual) exposure to credit losses when a securitization has transferred proportionately more credit risk than claims‐paying assets. The authors discuss the distinction between “gross” versus “net” transfers of credit risk. To illustrate this point, they provide conceptual examples of the net effect of an asset securitization on the residual credit risk retained by an issuer. In these examples, providing credit enhancement (e.g., overcollateralization, subordination) may implicitly lever or delever an issuer's balance sheet. The authors outline the general conditions under which this indirect economic recourse to the issuer, in effect a form of “self‐insurance,” may result in a net dilution of the claims of unsecured creditors.

Abstract
ONE or two questions raised by the writer of “Letters on our Affairs” this month are of some urgency. The first, the physical condition of books, is one that is long over‐due for full discussion with a view to complete revision of our method. The increased book fund of post‐war years, and the unexpected success of the twopenny library, have brought us to the point when we should concentrate upon beautiful and clean editions of good books, and encourage the public to use them. “Euripides” is quite right in his contention that there is too much dependence upon the outcasts of the circulating library for replenishing the stocks of public lending libraries. We say this gravely and advisedly. Many librarians depend almost entirely upon the off‐scourings of commercial libraries for their fiction. The result, of course, is contempt of that stock from all readers who are not without knowledge of books. It is the business of the public library now to scrap all books that are stained, unpleasant to the sight, in bad print, and otherwise unattractive. Of old, it was necessary for us to work hard, and by careful conservation of sometimes quite dirty books, in order to get enough books to serve our readers. To‐day this is no longer the case, except in quite backward areas. The average well‐supported public library—and there are many now in that category—should aim at a reduction of stock to proportions which are really useful, which are good and which are ultimately attractive if not beautiful. The time has arrived when a dirty book, or a poorly printed book, or a book which has no artistic appeal, should be regarded as a reproach to the library preserving it.

Abstract
AT the very outset of this paper it is necessary to make clear that it is not an attempt to compile an exhaustive bibliography of literature relating to special librarianship. Neither space nor time permit this. In fact, the references given can only claim to be a sample of the wealth of material on the subject and this paper is submitted in the hope that it will stimulate others to more scholarly efforts. Reference numbers throughout this paper refer to items in the ‘Select list of references to the literature of special librarianship’, section 2 onwards.

Abstract
Purpose
Flow separation on wings, blades and vehicles can be delayed or even suppressed by the use of vortex generators (VG). Numerous studies, documented in the literature, extensively describe the performance of triangular and rectangular VG winglets. This paper aims to focus on the use of non-conventional VG shapes, more specifically an array of trapezoildal-perforated VG tabs.
Design/methodology/approach
In this study, computational fluid dynamic simulations are performed on an inline array of trapezoidal VG with various dimensions and inclination angles, in addition to considering perforations in the VG centers. The methodology of the present numerical study is validated with experimental data from the literature.
Findings
The performance and the associated flow structures of these tested non-conventional VG are compared to classical triangular winglets. For the proposed non-conventional trapezoidal VG, at the onset of stall, a 21% increase of lift over drag on the airfoil is observed. The trapezoidal VG enhancement is also witnessed during stall where the lift over drag ratio is increased by 120% for the airfoil and by 10% with respect to the triangular winglets documented in the literature.
Originality/value
The originality of this paper is the use of non-conventional vortex generator shape to enhance lift over drag coefficient using three-dimensional numerical simulations.

Abstract
Purpose
The purpose of this paper is to focus specifically on the benefits of using mixed methods to investigate dietary change from adolescence to adulthood exemplified using the findings from the ASH30 longitudinal study. The ASH30 study is a longitudinal dietary survey which provided quantitative evidence of dietary change and investigated factors influencing dietary change from adolescence to adulthood.
Design/methodology/approach
Two three‐day food diaries were collected both in 1980 (aged 11‐12 years) and 2000 (aged 31‐32 years) from the same 198 respondents in North East England. In 2,000 questionnaires were used to collect perceptions of, and attributions for, dietary change and open‐ended responses were analysed using content analysis.
Findings
The use of mixed methods brings added breadth and depth to the research which cannot be achieved by a single discipline or method. Determining what has influenced change in dietary behaviour from adolescence to adulthood is a complex and multifaceted task. Eating habits are influenced by multiple factors throughout the life course. Change in food intake between adolescence and adulthood related to life‐course events and trajectories. The qualitative findings highlighted relevant contextual information such as themes of moral panics, the concept of “convenience” and “fresh” foods.
Practical implications
Adopting mixed method approaches to exploring dietary change should offer a rich perspective from which to base realistic interventions.
Originality/value
Longitudinal dietary surveys present an opportunity to understand the complex process of dietary change throughout the life course in terms both of how diets have changed but also of why they have changed.
