Scale of production and choice of technique in the engineering industries in developing countries

This article examines the relationship between scale of production, optimal choice of technique and costs for three engineering industries: nuts and bolts, iron founding and machine tools. In all three industries costs of production fell as the scale of output increased. This was associated with switches of technique and the spread of fixed costs over a larger number of units. The capital‐output ratio fell and labour productivity increased with increases in scale while, in most cases, the capital‐labour ratio increased. The implications of these findings are briefly discussed.     

Correlates of depressive symptoms in adolescents

The relationship between a number of social and cognitive variables and depressive symptomatology was evaluated in a sample of public middle-school and high-school students. The variables measured included stressful life events, locus of control, causal attributions, and means-ends problem-solving abilities. Higher levels of depression were found to be associated with a more external locus of control and a tendency to attribute outcomes to causes which are internal, stable, and global. Parental divorce and socioeconomic status were also found to be associated with higher levels of depression. No relationship was found to exist between either amount of life stress or problem-solving ability and depression. The implications of these results for delineating the underlying dimensions of depression in adolescents are discussed.Previously Dr. Siegel was in the Department of Clinical Psychology at the University of Florida.

A Multilevel Investigation of the Association between School Context and Adolescent Nonphysical Bullying

Although researchers have identified individual-level predictors of nonphysical bullying among children and youth, school-level predictors (i.e., characteristics of the school environment that influence bullying exposure) remain largely unstudied. Using data from a survey of 1,838 students in 21 Boston public high schools, we used multilevel modeling techniques to estimate the level of variation across schools in student reports of nonphysical bully victimization and identify school-level predictors of bullying. We found significant between school variation in youth reports of nonphysical bullying, with estimates ranging from 25-58%. We tested school-level indicators of academic performance, emotional well-being, and school safety. After controlling for individual-level covariates and demographic controls, the percent of students in the school who met with a mental health counselor was significantly associated with bullying (OR = 1.03, 95% CI = 1.01, 1.06). There was no significant association between school-level academic performance and perceptions of school safety on individual reports of bullying. Findings suggest that prevention and intervention programs may benefit from attending to the emotional well-being of students and support the importance of understanding the role of the school environment in shaping student experiences with bullying.     

HUNTER‐GATHERER COLLABORATIVE PRACTICE

This article describes the development of a practice group based on a hunter‐gatherer model, with the mission of providing high quality collaborative divorce services, with an emphasis on protecting children and divorcing partners, and expanding access to middle‐ and lower‐income families. The practice group professional disciplines include law, mental health divorce coaching, co‐parent coaching, financial analysis, and case administration. These professionals have collectively associated their individual practices to address challenges facing their collaborative practices. With common purpose, the practice group builds skills, generates client base, nurtures trust, and lays a common knowledge base. Collaborative divorce teams formed from its members serve divorcing families with efficient, cost‐conscious, interest‐based negotiation processes that protect children and help parties productively move on with their lives.     

Mock jurors' perceptions of identifications made by intoxicated eyewitnesses

Abstract

Psychology research has generally neglected intoxicated eyewitnesses. The current study addressed this need by exploring mock jurors' perceptions of intoxicated witnesses. Undergraduate participants read summarized sexual or aggravated battery cases in which either the victim or a bystander identified the defendant under varying intoxication levels. They answered questions about the case and provided verdicts. Participants were sensitive to the effect that intoxication may have on witnesses' cognitive ability, but not to varying degrees of intoxication. Neither the role of the eyewitness nor the type of crime committed had an effect on perceptions of witness impairment. Participants' perceptions of witness impairment informed identification credibility ratings, and credibility assessments affected verdicts. Impairment and credibility ratings fully mediated intoxication's effect on verdicts. Unlike much prior research, our results suggest that mock jurors can consider potentially important witness information when rendering verdicts.     

NEGOTIATING TECHNOLOGICAL CHANGE IN THE COMMONWEALTH BANKING CORPORATION

Abstract: In May and June 1981 Automatic Telling Machines (ATMs) were introduced into sixty-one branches of the Commonwealth Banking Corporation in New South Wales, Victoria and the ACT. In contrast to union bans which had been imposed on ATMs in the private banking sector, the Commonwealth Bank Officers' Association (CBOA) actively supported the use of this new technology. After outlining the industry industrial relations system this paper examines the three-way process of negotiations, involving the union, management and the federal government, which led to the introduction of ATMs. The terms of the agreement reached — a 19 day working month, early voluntary retirement after age 55 and a joint consultative committee on technological change in return for supports for ATMs — are analysed and the factors which contributed to the absence of industrial conflict during the negotiations are discussed.     

Long-term intracerebral inflammatory response after traumatic brain injury

Epidemiological and pathological studies suggest that head injury is a significant risk factor for subsequent neurodegeneration and cognitive decline in later life. The precise mechanisms for the development of post-traumatic neurodegenerative change are unclear but we hypothesize that persistence of inflammatory processes in the brain may play a key role and that some individuals are more susceptible to such changes based on their genetic make-up. In support of this hypothesis we present evidence of persistent elevated microglial activity in long-term survivors of head injury and the suggestion of an association between the extent of this activity and interleukin-1 genotype.     

The tangled web: does the internet offer promise or peril for the Chinese Communist Party?

This paper seeks to address the divide between political rhetoric and reality on the question of the impact of the Internet on China. Many politicians and pundits steadfastly promote the Internet as a conduit for democracy, without empirical proof to support their statements. Nowhere is this more apparent than in the debate over information technology and the Internet in China. The Chinese Communist Party is employing a number of approaches to control the Internet, from introducing numerous regulations to encouraging self‐censorship, with some success. This paper will examine state‐coordinated measures to control the use of the Internet, look at how the Internet could be making CCP rule more effective, and consider the validity of the argument that the Internet represents a threat to CCP rule.
