Representational predicaments for employees: Their impact on perceptions of supervisors\u27 individualized consideration and on employee job satisfaction
A representational predicament for a subordinate vis-à -vis his or her immediate superior involves perceptual incongruence with the superior about the subordinate\u27s work or work context, with unfavourable implications for the employee. An instrument to measure the incidence of two types of representational predicament, being neglected and negative slanting, was developed and then validated through an initial survey of 327 employees. A subsequent substantive survey with a fresh sample of 330 employees largely supported a conceptual model linking being neglected and negative slanting to perceptions of low individualized consideration by superiors and to low overall job satisfaction. The respondents in both surveys were all Hong Kong Chinese. Two case examples drawn from qualitative interviews illustrate and support the conceptual model. Based on the research findings, we recommend some practical exercises to use in training interventions with leaders and subordinates. © 2013 Copyright Taylor and Francis Group, LLC

Differential hypothalamic neuronal activation following peripheral injection of GLP-1 and oxyntomodulin in mice detected by manganese-enhanced magnetic resonance imaging
The anorexigenic gut hormones oxyntomodulin (OXM) and glucagon-like peptide-1 (GLP-1) are thought to physiologically regulate appetite and food intake. Using manganese-enhanced magnetic resonance imaging, we have shown distinct patterns of neuronal activation in the hypothalamus in response to intraperitoneal injections into fasted mice of 900 and 5400 nmol/kg OXM or 900 nmol/kg GLP-1. Administration of OXM at either dose resulted in a reduced rate of signal enhancement, reflecting a reduction in neuronal activity, in the arcuate, paraventricular, and supraoptic nuclei of the hypothalamus. Conversely, GLP-1 caused a reduction in signal enhancement in the paraventricular nucleus only and an increase in the ventromedial hypothalamic nucleus. Our data show that these two apparently similar peptides generate distinct patterns of activation within the hypothalamus, suggesting that GLP-1 and OXM may act via different hypothalamic pathways

Diversity of begomoviruses associated with mosaic disease of cultivated cassava (Manihot esculenta Crantz) and its wild relative (Manihot glaziovii Mull. Arg.) in Uganda
Cassava (Manihot esculenta) growing in Uganda during 2001–2002 has been screened for the
presence of begomoviruses using PCR-RFLP, cloning full-length genomic components and
nucleotide sequence analysis. In contrast with a recent survey in neighbouring Kenya, which
identified three distinct strains of East African cassava mosaic virus (EACMV, EACMV-UG and
EACMV-KE2) as well as East African cassava mosaic Zanzibar virus and the new species East
African cassava mosaic Kenya virus, only EACMV-UG and, to a lesser extent, African cassava
mosaic virus (ACMV) were found associated with cassava in Uganda. The integrity of the cloned
genomic components of representative virus isolates was confirmed by demonstrating their
infectivity in Nicotiana benthamiana and cassava using biolistic inoculation, providing a convenient
means to screen cassava varieties for disease resistance. Both EACMV-UG and ACMV were also
associated with Manihot glaziovii. Infectivity studies using cloned components confirmed that
viruses from one host could infect the other, suggesting that this wild relative of cassava might be
a reservoir host for the disease. The relatively low level of diversity of begomoviruses associated
with cassava mosaic disease in Uganda is consistent with reports that EACMV-UG has
displaced other begomovirus species and strains during the recent epidemic that swept through
the country
