Not What It Was and Not What It Will Be: The Future of Job Design Research

This summary commentary explores the likely future directions of research and theory on the design of organizational work. We give special attention to the social aspects of contemporary work, the process by which jobholders craft their own jobs, the changing contexts within which work is performed, and the increasing prominence of work that is performed by teams rather than individualsPsycholog

Animal production from tagasaste growing in deep sands in a 450 mm winter rainfall zone

In 1985, Martindale Pty Ltd, Sir James McCusker\u27s family company, signed a unique research contract with Professor David Lindsay of the University of Western Australia. The aim of the Martindale Research Project was to study ways of increasing farm productivity in the sheep-wheat zone of south-western Australia. A primary focus was the high cost of grain or hay used to fill the autumn feed gap in grazing systems. However, it was not clear how or if tagasaste might be economically used to replace the grain and/or hay traditionally fed by hand to sheep and cattle in autumn

Motivation through the Design of Work: Test of a Theory

A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motivated work behavior to develop; (b) the characteristics of jobs that can create these psychological states; and (c) the attributes of individuals that determine how positively a person will respond to a complex and challenging job. The model was tested for 658 employees who work on 62 different jobs in seven organizations, and results support its validity. A number of special features of the model are discussed (including its use as a basis for the diagnosis of jobs and the evaluation of job redesign projects), and the model is compared to other theories of job design

The Effect of Mobility and Strength Training on Firefighter Cadet Functional Mobility

Strength and Conditioning programs have positive effects on athletic performance (Hedrick, 2002). Similarly, firefighters have to be adequately fit to perform their job duties which require muscular strength and endurance, and aerobic fitness (Smith, 2011). Thus, firefighter’s health and fitness, including mobility, is crucial in their job performance. PURPOSE: We examined the effects of a strength, conditioning, and mobility program on functional mobility in firefighter cadets. METHODS: 43 firefighter cadets who were enrolled in a 12-week basic firefighter academy course participated. Cadets were separated into one of three cohorts; 1) No program; 2) Unmonitored Program; and 3) Indirectly Monitored Program. Participants either completed daily physical fitness training tasks on their own or set by fire instructors. A certified strength and conditioning specialist (CSCS) set up the physical fitness training modes for cohorts 2 and 3; however, the CSCS did not monitor training directly. Mobility was assessed by ROM exercises using DARI Motion Capture® (DARI Motion, Kansas City, Missouri). Motions included bodyweight bilateral squat, unilateral squat right and left, forward lunge right and left, and lateral lunge right and left. Post testing was completed 12-weeks after initial assessments. Statistical analysis was conducted using SPSS. RESULTS: Overall Cohort 3, Indirectly Monitored Program, had the greatest positive mobility changes when comparing pre post testing. There were significant increases in bodyweight squat left knee flexion in cohort three (115.58±16.0 to 124.56±16.42, p=0.02). Bodyweight squat left ankle flexion also significantly increased (24.20±11.78 to 34.98±12.03, p=0.005). Significant increases in bodyweight squat percentage of lower body height in cohort three were also positive (47.3±10.7% to 52.7±10.0%, p=0.037), indicating that greater squat depth was achieved after the indirectly monitored program. However, negative effects on the bodyweight squat includes left and right knee valgus both increasing showing a lack of stability in dynamic knee control while squatting (left: 4.65±1.33to 5.02±0.66, p=0.039; right: 3.97±2.06 to 4.87±1.33, p=0.005). Unilateral squat depth percentage of lower body showed significant changes in Cohort 3 (26.9±8.3% to 32.0±13.6%, p=0.032). Unilateral squat knee and ankle flexion both showed positive significant differences (knee: 83.70±18.05 to 94.62±23.49, p=0.02; ankle: 24.34±9.38 to 34.57±12.25, p=0.001). CONCLUSION: The results of the current study suggest that even indirect monitoring of tactical strength and conditioning programming can have a positive effect on firefighter cadet’s functional mobility. In the future, programming should be more direct including the installation of tactical personnel to aid and facilitate training programs with proper supervision

Win or lose the battle for creativity: The power and perils of intergroup competition

Integrating and refining social interdependence theory and structural adaptation theory, we examined the effects of intergroup competition on the creativity of 70 four-person groups engaged in two idea generation tasks. We manipulated both group membership change (change, no change) and intergroup competition level (low, intermediate, high). Competition had the expected U-shaped relation with creativity in open (membership change) groups but failed to produce the hypothesized inverted U-shaped pattern in closed (no membership change) groups. In the latter, effects were positive for low to intermediate competition and flat for intermediate to high levels. Within-group collaboration mediated these effects

Intergroup Competition as a Double-edged Sword: How Sex Composition Regulates the Effects of Competition on Group Creativity

Building on social role theory, we extend a contingency perspective on intergroup competition proposing that having groups compete against one another is stimulating to the creativity of groups composed largely or exclusively of men but detrimental to the creativity of groups composed largely or exclusively of women. We tested this idea in two separate studies: a laboratory experiment (Study 1) and a field study (Study 2). Study 1 showed that competition had the expected positive effects on the creativity of groups composed mostly or exclusively of men and produced the predicted negative effects on the creativity of groups composed of women, even though the latter effects emerged at the high end of the competition spectrum and for sex-homogeneous groups only. Results of Study 1 also revealed that within-group collaboration mediated the joint effects of competition and sex composition on group creativity. Study 2 replicated the results of Study 1 in a field setting involving research and development teams. We discuss the implications of these findings for theory and practice. </jats:p

Herpetological observations from field expeditions to North Karnataka and Southwest Maharashtra, India

The Western Ghats of India are one of the 34 global hotspots of biodiversity. They are one of the most important large natural areas in the world and are fast becoming recognised for their biological importance. The herpetofauna of the Western Ghats is hugely diverse, with many species exhibiting rare, endemic styles of autecology and niche preference that could equal that of countries such as Borneo and Madagascar. In this report we detail 18 amphibian and 37 reptile species from eight sites following three expeditions to the Western Ghats from 2007-2009. The report details species descriptions, habitat, ecology and conservation to alert the herpetological community to the importance of future research to address the lack of knowledge in species ecology. It also presents newinformation on species distribution and behaviour
