Infants’ Discrimination of Familiar and Unfamiliar Accents in Speech

This study investigates infants’ discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head‐turn preference procedure, 5‐month‐old infants demonstrated that they were able to distinguish between their own South‐West English accent and an unfamiliar Welsh English accent. However, this distinction was not seen when two unfamiliar accents (Welsh English and Scottish English) were presented to the infants, indicating they had not acquired the general ability to distinguish between regional varieties, but only the distinction between their home accent and unfamiliar regional variations. This ability was also confirmed with 7‐month‐olds, challenging recent claims that infants lose their sensitivity to dialects at around that age. Taken together, our results argue in favor of an early sensitivity to the intonation system of languages, and to the early learning of accent‐specific intonation and potentially segmental patterns. Implications for the development of accent normalization abilities are discussed.     

Reflective practice: action learning sets for managers in social work

The author evaluates action learning sets, established as part of a management development programme, for managers in social work. The impact on management practice, the processes contributing to effectiveness and the elements of learning that participants viewed as making most difference to their management practice are identified. The issues brought for consultation are described, including working with contradiction and paradox. It is concluded that participants experience action learning to make a positive contribution to their development as managers in a challenging environment.     

Estimation of long-run inefficiency levels: a dynamic frontier approach

Cornwell, Schmidt, and Sickles (1990) and Kumbhakar (1990), among others, developed stochasticfrontier production models which allow firm specific inefficiency levels to change over time. These studies assumed arbitrary restrictions on the short-run dynamics of efficiency levels which have little theoretical justification. Further, the models are inappropriate for estimation of long-run efficiencies. We consider estimation of an alternative frontier model in which firmspecific technical inefficiency levels are autoregressive. This model is particularly useful to examine a potential dynamic link between technical innovations and production inefficiency levels. We apply our methodology to a panel of US airlines.     

Mapping the boundaries of courtship disorder

The courtship disorder hypothesis maintains that voyeurism, exhibitionism, toucheurism‐frotteurism, and the preferential rape pattern are expressions of the same disorder (courtship disorder). Earlier studies had shown that with the exception of the preferential rape pattern these paraphilias co‐occur to a reasonably high degree. The present study (1) demonstrated that the preferential rape pattern co‐occurs with the above reasonably well established expressions of courtship disorder to a higher degree than other main paraphilic activity patterns do and (2) supported the conjecture that in addition to an erotic preference for unfamiliarity of target person‐or‐object (noted by earlier authors), three other paraphilic target‐person or object preferences may be connected with courtship disorder, though they are not at all virtually obligatory as is erotic unfamiliarity. These are choosing children and adults alike as target persons of the paraphilic activities, non‐gender dysphoric transvestism, and fetishism.     

Improving OpenURL Menus: User Testing of Revisions to SFX® Menus

Abstract

Twenty-one volunteers tested the usability of revisions to the Texas A&M University Libraries' SFX® OpenURL link resolver menus, including the addition of Ex Libris' new bXâ?¢ recommendation service and a plug-in which pulls additional information about the journal into the menu. The volunteers also evaluated the quality and desirability of the bX recommendations and discussed their preferences for help options and full-text format. Results of the usability testing are reported along with the resultant menu changes. This study will be of interest to librarians implementing or redesigning OpenURL menus as well as those interested in the user experience.     

Does Financial Satisfaction Vary Depending on the Funding Strategy Used to Pay for College?

This study sought to determine whether the levels of financial satisfaction reported by college undergraduates and graduates differ in relation to whether they funded their college education by working or borrowing or a combination of the two. Data for this study came from a survey sample of full-time freshmen that formed the basis of a longitudinal study conducted at a large public university. Funding sources examined were grouped into those who worked only, those who borrowed only, those who worked and borrowed, and those who used grants, scholarships, or other sources of money to fund their college education. Compared to those who had student loans, those who had financed college with grants, scholarships, or other money (usually from family and/or friends) were more likely to report greater financial satisfaction than those who had used student loans to pay for college. There was evidence that this was only true during college rather than after college. The results obtained suggest that merely possessing a student loan may not necessarily decrease the level of financial satisfaction as many suspect, especially considering other funding alternatives such as working during college. While there was no significant impact of these funding strategies on financial satisfaction either during or after college, there was evidence for possible thresholds at which overall student loan balances may begin to erode financial satisfaction. The results obtained suggest that student loans may not decrease the level of financial satisfaction as much as many have suspected when compared with working to pay for college, as long as the amount of the student loan is not excessive, and is not accompanied by other types of debt (which also reduced financial satisfaction).

     

Value managed relationships: The key to customer retention and profitability

The authors argue that customer satisfaction and retention are vital and can be improved by the technique which they call a Value Managed Relationship (VMR). A VMR is a collaborative, communicative partnership between suppliers and the supplier's customers, and it works by reducing system costs. Buchanan and Gillies point to examples in British industry where VMRs have been of great benefit.     

RECONSIDERING THE STIGMA OF PHYSICAL DISABILITY:

This article reexamines the stigma of physical disability using the empirical example of wheelchair users' treatment in public places. It draws upon conversational interviews with wheelchair users, field notes recorded during participant observation in public places while using wheelchairs, and previously published autobiographical accounts. The analysis of these materials primarily focuses upon the many public encounters in which wheelchair users request and receive various forms of assistance. Our analysis demonstrates that wheelchair users' place in public life is more uncertain and unsettled than the concepts deviance and stignia suggest. We argue for an empirical reassessment of the social definition of various physical disabilities through ethnographic study of relations between typical and atypical people and analytic attention to situated processes of identification.     

A sequential approximation to a permutation test

A sequential method for approximating a general permutation test (SAPT) is proposed and evaluated. Permutations are randomly generated from some set G, and a sequential probability ratio test (SPRT) is used to determine whether an observed test statistic falls sufficiently far in the tail of the permutation distribution to warrant rejecting some hypothesis. An estimate and bounds on the power function of the SPRT are used to find bounds on the effective significance level of the SAPT. Guidelines are developed for choosing parameters in order to obtain a desired significance level and minimize the number of permutations needed to reach a decision. A theoretical estimate of the average number of permutations under the null hypothesis is given along with simulation results demonstrating the power and average number of permutations for various alternatives. The sequential approximation retains the generality of the permutation test,- while avoiding the computational complexities that arise in attempting to computer the full permutation distribution exactly
