Teachers' Reactions to Children's Aggression

Drawing on social schema theory ( Fiske & Taylor, 1991 ) and social identity theory ( Tajfel & Turner, 1979 ), this study examined the impact on teachers’ reactions to children's aggression of three variables, two of which were related to the aggressors and one was related to the teachers. Experienced female elementary school teachers (N =90) each read a scenario that described an aggressive episode committed by a group of boys against a boy from another class. The aggressors were either good or bad children, who were either popular or unpopular with their classroom peers. In addition, the scenario manipulated the teachers’ identification with, or commitment to, the class to be either high or low. Analysis of the teachers’ ratings of causal responsibility, liking, and recommended punishment revealed a consistent negative response from the teachers towards the aggressors versus the victim. However, the teachers’ responses were also interactively influenced by the aggressors’ goodness and popularity, as well as the teachers’ class identification. The results are discussed in relation to other findings on teachers’ responses to school aggression and bullying, as well as how their responses might best be explained.     

Dynamic Logit With Choice Aversion

We characterize a generalization of discounted logistic choice that incorporates a parameter to capture different views the agent might have about the costs and benefits of larger choice sets. The discounted logit model used in the empirical literature is the special case that displays a “preference for flexibility” in the sense that the agent always prefers to add additional items to a menu. Other cases display varying levels of “choice aversion,” where the agent prefers to remove items from a menu if their ex ante value is below a threshold. We show that higher choice aversion, as measured by dislike of bigger menus, also corresponds to an increased preference for putting off decisions as late as possible.     

Scheduling in a Management Context: Uncertain Processing Times and Non-Regular Performance Measures*

Decision makers often face scheduling problems in which processing times are not known with certainty. Non-regular performance measures, in which both earliness and tardiness are penalized, are also becoming more common in both manufacturing and service operations. We model a managerial environment with task processing times (which include sequenceindependent set-up times) prescribed by three-parameter lognormal distributions. Upon completion, each task derives a reward given by a particular piecewise-linear reward function. The objective is to select a sequence of tasks maximizing the expected total reward. The relative generality of the problem renders many enumerative methods inapplicable or computationally intractable. To overcome such difficulties we develop efficient priorityinduced construction (PIC) heuristics which build up a complete schedule by inserting tasks (singly from a list) into a partial sequence of tasks. In each partial and complete sequence a period of idle time is permitted prior to the first task. Performance on realistic-sized problems is very encouraging, with cost penalties averaging less than one percent.     

Determinants of business success: an examination of Asian-owned businesses in the USA

Using confidential microdata from the US Census Bureau, we investigate the performance of Asian-owned businesses. Using regression estimates and a special non-linear decomposition technique, we explore the role that class resources, such as financial capital and human capital, play in contributing to the relative success of Asian businesses. We find that Asian-owned businesses are more successful than white-owned businesses for two main reasons—Asian owners have high levels of human capital and their businesses have substantial start-up capital. Using detailed information on both the owner and the firm, we estimate the explanatory power of several additional factors.

Disability,personalisation and community arts: exploring the spatial dynamics of children with disabilities participating in inclusive music classes*

This paper uses personalisation and the capabilities approach to explore inclusive music classes for children with disabilities in Scotland. It provides a unique insight into the impact of participation through the voices of the disabled young musicians, their parents and tutors. The study highlights the power of inclusive spaces to transform lives, to build confidence and contest disabled identities. It engages in the spatial dynamic of opening up inclusive spaces, as well as exposing emerging tensions in the liminal space that is created through movement between safe and supported spaces and the antithesis, spaces that disempower and marginalise. The findings suggest good practice around personalisation, when conceived of from a social justice perspective, as a template for working with other marginalised groups and in other professional settings.     

Jia’s The Chinese Version

Abstract

The Chinese Character Simplification Programme of 1955–1957 that remains a national standard by force of law in the People’s Republic of China, not only degraded the aesthetic properties of the Chinese written character, but also hindered literacy by means of a haphazard formal reduction of the number of strokes, and by eliminating two-thirds of characters from the lexicon of those allowed for publication. In The Chinese Version painting series by Jia (b.1979), the artist arranges Chinese characters according to formal rather than semantic criteria, in order to generate by means of their juxtaposition, abstract or figurative patterns. Each character may retain its individual meaning, but not its function as a sequential syntagm. This strategy invests the characters with a formal aspect to ‘return’ that which was mutilated by the Simplification Programme. As the Simplification Programme’s formal changes ended characters’ role as image-signs, the artist’s choice to present each work as a painting alludes to their lost image capacity while appearing to imitate the outward aspect of printed characters, thereby implicitly turning against itself the pretext of character simplification for the sake of efficiency.     

Wiki-worthy: collective judgment of candidate notability

The use of socio-technical data to predict elections is a growing research area. We argue that election prediction research suffers from under-specified theoretical models that do not properly distinguish between ‘poll-like’ and ‘prediction market-like’ mechanisms understand findings. More specifically, we argue that, in systems with strong norms and reputational feedback mechanisms, individuals have market-like incentives to bias content creation toward candidates they expect will win. We provide evidence for the merits of this approach using the creation of Wikipedia pages for candidates in the 2010 US and UK national legislative elections. We find that Wikipedia editors are more likely to create Wikipedia pages for challengers who have a better chance of defeating their incumbent opponent and that the timing of these page creations coincides with periods when collective expectations for the candidate's success are relatively high.
