Path dependency and the role of HR

Path dependency is used to assess the dynamics and evolution of workplace experiences in both the New Zealand Public Sector, and the marginalisation of the HRM function in the United Kingdom. In the New Zealand public sector a controlling management style, but weak leadership and low organisational capability came from the freedom-to-manage and accountability ethos of the new public management reforms. These current features then became entrenched through processes such as: learning effects and reward systems as a new cohort of managers rose through the ranks; managerial norms and implicit theories of human behaviours that included a disinterest in socio-technical concepts and strategic HRM. A controlling management style and weak leadership complimented other behaviours and practices, such as risk aversion, and the rise of Ministerial policy advice at the expense of other practices such as service delivery. In the case of UK HRM managers, the GFC provided an opportunity for the HRM function to escape from its traditional marginalised role. However GFC induced innovations such as the implementation of e-HR and service centres further removed the HRM function from strategic conversations and left them as contract managers. The paper ends with an outline of further planned research on how HRM can shift toward a more strategic function

Public servants want to make a difference

New Zealand public servants are generally satisfied with their jobs and want to make a difference to society, although they have mixed feelings about their organisations. To understand this discrepancy between what they feel about their jobs and what they feel about their employers, this article – the second of two analysing the results of a survey of almost 16,000 PSA members in 2013– looks at respondents’ characteristics, attitudes and experiences in the workplace

CLEW'D IN April 2015

Poor leadership, weak people management and flawed upward information flows are contributing to the stagnation of public sector productivity, participants at a recent seminar were told. A change in focus for the HR profession is also required to create high-performing public agencies. Senior public sector leaders who spoke at the seminar included Productivity Commission chairperson Murray Sherwin and Department of Internal Affairs chief executive Colin MacDonald

What You Feel Is What I Do: A Study of Dynamic Haptic Interaction in Distributed Collaborative Virtual Environment

In this paper we present the concept of “What You Feel Is What I Do (WYFIWID)”. The concept is fundamentally based on a haptic guide that allows an expert to control the hand of a remot trainee. When haptic guide is active then all movements of the expert’s hand (via input device) in the 3D space are haptically reproduced by the trainee’s hand via a force feedback device. We use haptic guide to control the trainee’s hand for writing alphabets and drawing geometrical forms. Twenty subjects participated in the experiments to evaluate

Laser cooling of a diatomic molecule

It has been roughly three decades since laser cooling techniques produced ultracold atoms, leading to rapid advances in a vast array of fields. Unfortunately laser cooling has not yet been extended to molecules because of their complex internal structure. However, this complexity makes molecules potentially useful for many applications. For example, heteronuclear molecules possess permanent electric dipole moments which lead to long-range, tunable, anisotropic dipole-dipole interactions. The combination of the dipole-dipole interaction and the precise control over molecular degrees of freedom possible at ultracold temperatures make ultracold molecules attractive candidates for use in quantum simulation of condensed matter systems and quantum computation. Also ultracold molecules may provide unique opportunities for studying chemical dynamics and for tests of fundamental symmetries. Here we experimentally demonstrate laser cooling of the molecule strontium monofluoride (SrF). Using an optical cycling scheme requiring only three lasers, we have observed both Sisyphus and Doppler cooling forces which have substantially reduced the transverse temperature of a SrF molecular beam. Currently the only technique for producing ultracold molecules is by binding together ultracold alkali atoms through Feshbach resonance or photoassociation. By contrast, different proposed applications for ultracold molecules require a variety of molecular energy-level structures. Our method provides a new route to ultracold temperatures for molecules. In particular it bridges the gap between ultracold temperatures and the ~1 K temperatures attainable with directly cooled molecules (e.g. cryogenic buffer gas cooling or decelerated supersonic beams). Ultimately our technique should enable the production of large samples of molecules at ultracold temperatures for species that are chemically distinct from bialkalis.Comment: 10 pages, 7 figure

Semen quality in Peruvian pesticide applicators: association between urinary organophosphate metabolites and semen parameters

<p>Abstract</p> <p>Background</p> <p>Organophosphates are broad class of chemicals widely used as pesticides throughout the world. We performed a cross-sectional study of associations between dialkylphosphate metabolites of organophosphates and semen quality among pesticide applicators in Majes (Arequipa), Peru.</p> <p>Methods</p> <p>Thirty-one men exposed to organophosphate (OP) pesticides and 31 non-exposed were recruited (age, 20–60 years). In exposed subjects, semen and a blood sample were obtained one day after the last pesticide application. Subjects were grouped according to levels of OP metabolites in urine. Semen samples were analyzed for sperm concentration, percentage of sperm motility, percentage of normal morphology, semen leucocytes and concentrations of fructose and zinc. Exposure to OP was assessed by measuring six urinary OP metabolites (dimethyl and diethyl phosphates and thiophosphates) by gas chromatography using a single flame photometric detector.</p> <p>Results</p> <p>Diethyldithiophosphate (p = 0.04) and diethylthiophosphate (p = 0.02) better reflected occupational pesticide exposure than other OP metabolites. Semen analysis revealed a significant reduction of semen volume and an increase in semen pH in men with OP metabolites. Multiple regression analysis showed that both occupational exposure to pesticides and the time of exposure to pesticides were more closely related to alterations in semen quality parameters than the single measurement of OP metabolites in urine.</p> <p>Conclusion</p> <p>The study demonstrated that occupational exposure to OP pesticides was more closely related to alterations in semen quality than a single measurement of urine OP metabolites. Current measurement of OP metabolites in urine may not reflect the full risk.</p

Evaluating the Effects of SARS-CoV-2 Spike Mutation D614G on Transmissibility and Pathogenicity.

Global dispersal and increasing frequency of the SARS-CoV-2 spike protein variant D614G are suggestive of a selective advantage but may also be due to a random founder effect. We investigate the hypothesis for positive selection of spike D614G in the United Kingdom using more than 25,000 whole genome SARS-CoV-2 sequences. Despite the availability of a large dataset, well represented by both spike 614 variants, not all approaches showed a conclusive signal of positive selection. Population genetic analysis indicates that 614G increases in frequency relative to 614D in a manner consistent with a selective advantage. We do not find any indication that patients infected with the spike 614G variant have higher COVID-19 mortality or clinical severity, but 614G is associated with higher viral load and younger age of patients. Significant differences in growth and size of 614G phylogenetic clusters indicate a need for continued study of this variant
