Examining the Relationships Among Categorization, Stereotype Activation, and Stereotype Application.

Increased category salience is associated with increased stereotyping. Prior research has not examined the processes that may account for this relationship. That is, it is unclear whether category salience leads to increased stereotyping by increasing stereotype activation (i.e., increased accessibility of stereotypic information), application (i.e., increasing the tendency to apply activated stereotypes), or both processes simultaneously. We examined this question across three studies by manipulating category salience in an implicit stereotyping measure and by applying a process model that provides independent estimates of stereotype activation and application. Our results replicated past findings that category salience increases stereotyping. Modeling results showed that category salience consistently increased the extent of stereotype application but increased stereotype activation in more limited contexts. Implications for models of social categorization and stereotyping are discussed

Zero-error channel capacity and simulation assisted by non-local correlations

Shannon's theory of zero-error communication is re-examined in the broader setting of using one classical channel to simulate another exactly, and in the presence of various resources that are all classes of non-signalling correlations: Shared randomness, shared entanglement and arbitrary non-signalling correlations. Specifically, when the channel being simulated is noiseless, this reduces to the zero-error capacity of the channel, assisted by the various classes of non-signalling correlations. When the resource channel is noiseless, it results in the "reverse" problem of simulating a noisy channel exactly by a noiseless one, assisted by correlations. In both cases, 'one-shot' separations between the power of the different assisting correlations are exhibited. The most striking result of this kind is that entanglement can assist in zero-error communication, in stark contrast to the standard setting of communicaton with asymptotically vanishing error in which entanglement does not help at all. In the asymptotic case, shared randomness is shown to be just as powerful as arbitrary non-signalling correlations for noisy channel simulation, which is not true for the asymptotic zero-error capacities. For assistance by arbitrary non-signalling correlations, linear programming formulas for capacity and simulation are derived, the former being equal (for channels with non-zero unassisted capacity) to the feedback-assisted zero-error capacity originally derived by Shannon to upper bound the unassisted zero-error capacity. Finally, a kind of reversibility between non-signalling-assisted capacity and simulation is observed, mirroring the famous "reverse Shannon theorem".Comment: 18 pages, 1 figure.

Factors influencing the decision to choose information technology preparatory studies in secondary schools: an exploratory study in regional/rural Australia

[Abstract]: The career paths of students are influenced and shaped by the subject choices that are made in the final years of secondary schooling. This paper presents the findings of an empirical study that identified the key factors influencing the decision of rural / regional Australian students to choose or not choose to study Information Processing and Technology. The findings revealed that career oriented, extrinsic factors play an important role in motivating the selection of I.P.T. at school and, by implication, information technology at university. There are few apparent gender differences but there is limited evidence to suggest that males may be more influenced by extrinsic motivators and females by intrinsic motivators. Although the factors used in the study were initially identified largely via informal processes, they all appear to influence the decision to take I.P.T. The focus on career-related factors and the instrumentality of taking I.P.T. could explain the drop-off in students taking the subject. This has potentially significant implications as regards the future supply of good information technology professional

The effects of day and night temperature on Chrysanthemum morifolium: investigating the safe limits for temperature integration

The impact of day and night temperatures on pot chrysanthemum (cultivars ‘Covington’ and ‘Irvine’) was assessed by exposing cuttings, stuck in weeks 39, 44, and 49, to different temperature regimes in short-days. Glasshouse heating setpoints of 12°, 15°, 18°, and 21°C, were used during the day, with venting at 2°C above these set-points. Night temperatures were then automatically manipulated to ensure that all of the treatments achieved similar mean diurnal temperatures. Plants were grown according to commercial practice and the experiment was repeated over 2 years. Increasing the day temperature from approx. 19°C to 21°C, and compensating by reducing the night temperature, did not have a significant impact on flowering time, although plant height was increased.This suggests that a temperature integration strategy which involves higher vent temperatures, and exploiting solar gain to give higher than normal day temperatures, should have minimal impact on crop scheduling. However, lowering the day-time temperature to approx. 16°C, and compensating with a warmer night, delayed flowering by up to 2 weeks. Therefore, a strategy whereby, in Winter, more heat is added at night under a thermally-efficient blackout screen may result in flowering delays.Transfers between the temperature regimes showed that the flowering delays were proportional to the amount of time spent in a low day-time temperature regime. Plants flowered at the same time, irrespective of whether they were transferred on a 1-, 2-, or 4-week cycle

Salesperson Performance, Satisfaction and Turnover: A Review, a Reconceptualization and an Empirical Investigation.

Search for a meaningful relationship between job satisfaction and job performance has continued for more than three decades. Despite ongoing theoretical, empirical and practical interest, research findings have been inconclusive. Literature reviews indicate that there still exists much confusion concerning the relationship between satisfaction and performance. Three conceptualizations of the relationship between satisfaction and performance have been proposed: (1) satisfaction is an antecedent of performance (a view associated with the early human relations school of thought); (2) the view that performance leads to satisfaction (through its impact on intrinsic and extrinsic rewards); and (3) the view that the relationship between satisfaction and performance is moderated by other variables. Each of these conceptualizations have been empirically tested. Employee turnover has received attention from both managers and academicians for many years. The conditions which lead to an individual\u27s decision to leave an organization are not fully understood today, despite many years of research attention. Of particular interest to the dissertation research was the interaction of individuals and their environment in predicting employee performance, job satisfaction and employee turnover in a sales setting. Therefore, this study examined individual variables, situational variables, and their interaction. It also addressed possible factors related to the lack of consensus regarding job satisfaction, employee performance and employee turnover (i.e., theoretical, measurement and methodological issues)
