    The Future of Human Resources: A Shift to a Network Driven Approach

    [Excerpt] As companies continue to thrive in a global context, the nature of work and organizational relationships will grow increasingly complex. Initiatives will span across traditional functional and geographical boundaries, heightening the need for greater knowledge sharing and collaboration. With a higher premium placed on achieving flexibility and agility, organizations that rely on strong internal networks have been more successful at coordinating efficiency and innovation. From a talent management perspective, organizations will need to adopt a more network-centric approach to foster leadership effectiveness within this new context. Just as the human resources arena has recently evolved from an individual-focused, personnel-service mindset to a team-oriented framework, the next decade may require human capital strategies to further shift to a network-driven mentality

    Psychopathology and Creativity Among Creative and Non-Creative Professions

    The mad genius debate has been a topic that has been discussed in both popular culture and academic discourse. The current study sought to replicate previous findings that linked psychopathology to creativity. A total of 165 biographies of eminent professionals (artists, scientists, athletes) were rated on 19 mental disorders using a three point scale of not present (0), probable (1), and present (2) for potential symptoms. Athletes served as an eminent but not creative comparison group in order to discern whether fame, independent of creativity, was associated with psychopathology. Comparison of proportion analyses were conducted to identify differences of proportion between these three groups for each psychopathology. Tests for one proportion were calculated to compare each group’s rates of psychopathology to the rates found in the U.S. population. These analyses were run twice, where subjects were dichotomized into present and not present categories; first, “present” included “probable” (inclusive) and second where it included only “present” (exclusive). Artists showed greater frequency rates of psychopathology than scientists and athletes in the more inclusive criteria for inclusion, whereas both artists and athletes showed greater frequency rates than scientists in the stricter criteria. Apart from anxiety disorder, athletes did not differ from the U.S. population in rates of psychopathology whereas artists differed from the population in terms of alcoholism, anxiety disorder, drug abuse, and depression. These data generally corroborate previous research on the link between creativity and psychopathology

    “Do Not Kill Guinea Pig before Setting up Apparatus”: The Kymograph's Lost Educational Context

    The objects of science education are transformed, degraded and disappeared for many reasons, and sometimes take other things with them when they go. This close reading of an undergraduate physiology laboratory report demonstrates how the kymograph was never a stand-alone instrument, but intertwined with conceptual frameworks and technical skills, laboratory amenities, materials, animal supply, technicians. Replacing the obsolete kymograph entails changing all of that, though our usual stories are focussed on progress associated with better measurements with fewer complications, not complications themselves. Such interconnectedness between progress and demise raises uncomfortable challenges for laboratory pedagogy, and for museum practice: what is laboratory education really about, and what kinds of heritage should museums, libraries and archives preserve to document it

    Genotyping of human and animal isolates of Giardia intestinalis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University

    Giardia intestinalis is an important protozoan parasite that infects humans and animals. It has been suggested that cattle may be a major source of human Giardia infection so a dairy farming region of New Zealand was investigated. This thesis uses three molecular methods to genotype G. intestinalis isolates obtained from human and animal faecal specimens collected in the Waikato region of New Zealand, to determine if giardiasis is a zoonotic disease. Random amplification of polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP) fingerprinting techniques were initially assessed for their ability to genotype G. intestinalis isolates. "Clear cut" evidence of zoonosis could not be established by either method, due to a low sample number. To determine the stability of the G. intestinalis genome an axenic culture of G. intestinalis trophozoites was stressed with toxic levels of metronidazole and the survivors, following a number of passages, were examined using AFLP and RAPD analysis. The DNA fingerprints were compared to those of the original wild-type with the results being indicative of an unstable G. intestinalis genome. A third molecular method was employed, which amplifies a portion of the tandemly repeated ribosomal DNA (rDNA). Each cyst contains 512 head to tail tandem repeat copies of the rRNA gene made up of both conserved and variable regions. The use of nested primers increased the sensitivity and specificity of the PCR reaction allowing the amplification of a 505bp rDNA fragment. DNA sequence analysis and alignment of the amplified products facilitated the comparison of G. intestinalis isolates. The relationship of the sequence data was generated and displayed using Splitstree software indicating that zoonosis did occur

    Constant threshold correction to electrically charged dilatonic black holes

    We investigate the effect of a constant threshold correction to a general non-extreme, static, spherically symmetric, electrically charged black hole solution of the dilatonic Einstein-Maxwell Lagrangian, with an arbitrary coupling β\beta between the electromagnetic tensor and the dilaton field. For a small β\beta, an exact analytical solution is obtained. For an arbitrary β\beta, a close form solution, up to first order in the threshold correction, of the metric and the dilaton are presented. In the extremal limit, the close form solution is reduced to an exact analytical form.Comment: LaTex with RevTex, 8 page
