The Ethics of Researching Friends: On Convenience Sampling in Qualitative Management and Organization Studies

Scholarship on the ethical complexities resulting from friendships which develop with respondents during qualitative data collection is well established. There has also been consideration of the ethics of researching existing friends across various disciplines. But, although management and organization scholars use convenience samples of the latter kind in qualitative research, there is virtually no discussion in our field of the ethical implications. In seeking to rectify this, I draw on my experiences of a project where I gathered data from six friends on their experiences of and attitudes towards sexual relationships, motherhood and life–work ‘balance’. I discuss the reportage of what sometimes felt like confidences, the use of ex ante data, the objectification of participants and difficulties relating to respondent validation in order to highlight some of the ethical challenges in qualitative management and organizational research with friends.     

Looking After Children: a case of individualised service delivery

This is a discussion of the debate in the literature on the new Looking After Children system of managing out of home care for children. This is an important program initiative in results‐oriented government that takes an individualised approach to children in care. The literature generally falls into the two categories of either relatively uncritical advocacy of LAC or its wholesale critique. These two camps pass as ships in the night and echo polarised epistemologies within policy analysis. There is very little analytical attention to LAC as an instance of the wider human service trends of individualised planning and case management.     

Gestural development and its relation to cognition during the transition to language

Four Parisian-French infants, two male and two female, were observed bi-weekly at home with their parents or caretakers from 9 or 10 months until approximately 14 months. Their entire repertoire of communicative gestures was coded from videorecordings. Comment gestures, particularly pointing in a book and showing an object, increased after 11 months, and Request gestures involving the adult as an agent increased after 13 months. The appearance of these specific gestures followed the ability to perform object permanence tasks with visible displacements and means-ends tasks involving obtaining an object by pulling a string horizontally. More primitive Reach-request and Emotive gestures declined after 11 months. These findings are compared to those obtained from English-Canadian infants followed over the same age period.Portions of this paper were presented at the Vth European Conference in Developmental Psychology held in Seville in September, 1992. This research was supported by a fellowship to the first author from the Fondation Fyssen, Paris. The filming equipment was supplied by the Centre National de la Recherche Scientifique, Blvd. Raspail, Paris. We are very grateful to the French families for their cooperation and to Nurit Nadler and Grace Borzellino for their assistance in the coding of the gestures.     

Philanthropic styles

The challenge of resource development, particularly among major donors, has led nonprofits to adopt marketing techniques, including market segmentation. The benefit segmentation approach used in this study of the giving motivations of 218 major donors reveals seven philanthropic styles: (1) Communitarians, (2) the Devout, (3) Investors, (4) Socialites, (5) Repayers, (6) Altruists, and (7) Dynasts. Examples of how knowledge of philanthropic styles can aid in nonprofit resource development are provided.     

Anxiety, Politics and Critical Management Education

The focus of this paper is a discussion of anxiety and politics as they relate to business school pedagogy. Using ideas from critical management education (CME), the paper explores why and how to engage with the anxiety mobilized through attempts to learn. The aim is to discuss emotional and political dynamics that are generated, and too often avoided, in management education. Making these dynamics overt in the classroom can help managers to comprehend the political context within which management takes place. Examples informed by CME are presented, as well as reflections from the author on the anxiety and politics that emerge for the critical management educator in a business school context. The contribution in the paper is to show the way that anxieties and politics within the business school classroom offer opportunities to change how business schools approach the teaching of managers. CME adds value to management education because it challenges what and how individuals and groups expect to learn, and consequently it challenges assumptions about how learning takes place within business schools. Such challenges are seen as an important and integral part of 'making the business school more critical'.     

Subhypergraph counts in extremal and random hypergraphs and the fractional <Emphasis Type="Italic">q</Emphasis>-independence

We study the extremal parameter N(n,m,H) which is the largest number of copies of a hypergraph H that can be formed of at most n vertices and m edges. Generalizing previous work of Alon (Isr. J. Math. 38:116–130, 1981), Friedgut and Kahn (Isr. J. Math. 105:251–256, 1998) and Janson, Oleszkiewicz and the third author (Isr. J. Math. 142:61–92, 2004), we obtain an asymptotic formula for N(n,m,H) which is strongly related to the solution α _q (H) of a linear programming problem, called here the fractional q-independence number of H. We observe that α _q (H) is a piecewise linear function of q and determine it explicitly for some ranges of q and some classes of H. As an application, we derive exponential bounds on the upper tail of the distribution of the number of copies of H in a random hypergraph.     

Simulation Study on Improved Shapiro–Wilk Tests for Normality

The article concerns tests for normality based on the Shapiro–Wilk W statistic. The constants in the test statistic are recalculated as those given in Shapiro and Wilk are incorrect. The empirical significance levels and power of improved tests have been evaluated in simulation study and compared to original ones. The improved tests were also applied to the multivariate case. In this case, we consider two implementations of the W statistic, the first one proposed by Srivastava and Hui and the other by Hanusz and Tarasinska. Empirical size of tests and their power have been compared to the Henze–Zirkler test.
