Implementing the Leader Development That Counts

Effective leader development is too often the first casualty of high demands placed on leaders, from corporate America to the U.S. military. A comparison of these entities’ common leader development programs and workforce feedback reveals insufficient strategies and competing priorities. Organizations succumbing to these obstacles unknowingly find themselves trapped in adverse cycles of leadership development, perpetuating undernourished talent and mediocre performance. This problem will not fix itself. Organizations must refocus efforts to understand and implement a leader driven, interpersonally focused, and culturally ingrained brand of leader development to maximize available talent in crafting their envisioned organization

Social attitudes modulate automatic imitation

In naturalistic interpersonal settings, mimicry or ‘automatic imitation’ generates liking, affiliation, cooperation and other positive social attitudes. The purpose of this study was to find out whether the relationship between social attitudes and mimicry is bidirectional: Do social attitudes have a direct and specific effect on mimicry? Participants were primed with pro-social, neutral or anti-social words in a scrambled sentence task. They were then tested for mimicry using a stimulus-response compatibility procedure. In this procedure, participants were required to perform a pre-specified movement (e.g. opening their hand) on presentation of a compatible (open) or incompatible (close) hand movement. Reaction time data were collected using electromyography (EMG) and the magnitude of the mimicry / automatic imitation effect was calculated by subtracting reaction times on compatible trials from those on incompatible trials. Pro-social priming produced a larger automatic imitation effect than anti-social priming, indicating that the relationship between mimicry and social attitudes is bidirectional, and that social attitudes have a direct and specific effect on the tendency to imitate behavior without intention or conscious awareness

Computer Modelling as an Aid to Forest and Woodland Restoration

Reclamation of terrestrial ecosystems tends to be focussed on two main land uses, mining and degraded agricultural or forested lands. Modelling has great potential to assist in both situations. The aim of many restoration programs is to restore biodiversity and a self-sustaining, fully functional ecosystem, which is intimately linked with the return of the plants, the vertebrates and, particularly, the invertebrate fauna, whose presence plays a pivotal role in most ecosystem functions and processes. A thorough understanding of these plant-fauna associations is essential if restoration is to succeed. It could also equip us with the knowledge to decide how minimalistic our information needs can be when modelling progress with restoration, for instance: by quantifying certain biophysical parameters; these plus certain vegetation indices; or by both plus a range of faunal attributes. As well as streamlining the restoration monitoring process, this could lead to the enhancement of the conservation value of the restoration, and a clear understanding of the ecological links between flora and fauna would also help develop bioindicators as components of completion criteria schedules. Using Western Australian bauxite mining in the Jarrah (Eucalyptus marginata) forest as a case study, this paper reviews rehabilitation prescriptions and trends in development of plant assemblages, invertebrate colonization and litter decomposition, and applies a systems dynamic modelling approach model to test assumptions regarding the evolution of plant-fauna assemblages in time and assess whether it is feasible to predict temporal changes in the rehabilitation of this ecosystem. Secondly, in relation to efforts to purchase and rehabilitate land to reconnect remnant woodland vegetation close to the south coast of Western Australia, network analysis and multi-level simulations are applied in order to decide the best locations to acquire land and to restore it in order to optimise connectivity

Re United Steelworkers of America, Local 4444, and Stanley Steel Co Ltd (Hamilton Plant)

The company assigned non-bargaining unit employees to the tasks involved with inventory taking. The collective agreement provided that Supervisors will not do work ordinarily performed by bargain­ing unit employees, except — (a) Instruction and training of employees. (b) Emergency work necessary to maintain an uninterrupted flow of production. Held, by a majority of the board of arbitration, W. Stetson dissenting, the grievance was dismissed. Inventory taking is not work ordinarily performed by bargaining unit employees . While some of the regular operations of the grieving bargaining unit employees may have been performed incidentally to the inventory taking, this does not mean that supervisors on performing this type of task have infringed upon the grievors\u27 jobs. Inventory taking requires judgment and special knowledge

Re United Electrical Workers, Local 523, and Welland Forge Ltd

Employee Grievance alleging failure to pay full pay for certain holidays. The facts: There was no real dispute between the parties about the facts. I should perhaps note at the outset that in its written statement of facts submitted to the board the union treats both grievances as relating to the July 1st holiday. The com-pany\u27s statement of facts, on the other hand, treats McHarg\u27s grievance as relating to the August 4th holiday. McHarg\u27s grievance form itself does not indicate to which holiday it relates. He was sick for both of them and it is a reasonable inference that his grievance, which is expressed in terms of a grievance against failure to pay for one holiday only, relates to the more recent of them. In any case, nothing turns on this discrepancy between the submission of the union and the submission of the company

PAR1 activation initiates integrin engagement and outside-in signalling in megakaryoblastic CHRF-288 cells

AbstractTo better understand the means by which cells such as human platelets regulate the binding of the integrin αIIbβ3 to fibrinogen, we have examined agonist-initiated inside-out and outside-in signalling in CHRF-288 cells, a megakaryoblastic cell line that expresses αIIbβ3 and the human thrombin receptor, PAR1. The results show several notable similarities and differences. (1) Activation of PAR1 caused CHRF-288 cells to adhere and spread on immobilized fibrinogen in an αIIbβ3-dependent manner, but did not support the binding of soluble fibrinogen or PAC-1, an antibody specific for activated αIIbβ3. (2) Direct activation of protein kinase C with PMA or disruption of the actin cytoskeleton with low concentrations of cytochalasin D also caused CHRF-288 cells to adhere to fibrinogen. (3) Despite the failure to bind soluble fibrinogen, activation of PAR1 in CHRF-288 cells caused phosphoinositide hydrolysis, arachidonate mobilization and the phosphorylation of p42MAPK, phospholipase A2 and the Rac exchange protein, Vav, all of which occur in platelets. PAR1 activation also caused an increase in cytosolic Ca2+, which, when prevented, blocked adhesion to fibrinogen. (4) Finally, as in platelets, adhesion of CHRF-288 cells to fibrinogen was followed by a burst of integrin-dependent (‘outside-in’) signalling, marked by FAK phosphorylation and a more prolonged phosphorylation of p42MAPK. However, in contrast to platelets, adhesion to fibrinogen had no effect on Vav phosphorylation. Collectively, these observations show that signalling initiated through PAR1 in CHRF-288 cells can support αIIbβ3 binding to immobilized ligand, but not the full integrin activation needed to bind soluble ligand. This would suggest that there has been an increase in integrin avidity without an accompanying increase in affinity. Such increases in avidity are thought to be due to integrin clustering, which would also explain the results obtained with cytochalasin D. The failure of αIIbβ3 to achieve the high affinity state in CHRF-288 cells was not due to the failure of PAR1 activation to initiate a number of signalling events that normally accompany platelet activation nor did it prevent at least some forms of outside-in signalling. However, at least one marker of outside-in signalling, the augmentation of Vav phosphorylation seen during platelet aggregation, did not occur in CHRF-288 cells
