The dimensionality of self-rated employee performance : an integrated view
This study addresses the debate in the literature regarding the dimensionality of the job performance construct. The sample comprised 647 public servants from a state-based law enforcement organisation. Exploratory and confirmatory factor analyses delineate a four:factor structure, consisting of in-role behaviour, organisational citizenship behaviour directed towards (1) individuals or (2) the organisation, and a distinct latent variable deemed counter-productive work behaviour (CWB). The pattern of correlations among the four performance dimensions and between the performance dimensions and attitudes support the construct and discriminant validity of the four performance dimensions. Further, the .findings propose that CWB is a core, not discretionary, dimension of performance.<br /
Micro-Structured Ferromagnetic Tubes for Spin Wave Excitation
Micron scale ferromagnetic tubes placed on the ends of ferromagnetic CoTaZr
spin waveguides are explored in order to enhance the excitation of Backward
Volume Magnetostatic Spin Waves. The tubes produce a closed magnetic circuit
about the signal line of the coplanar waveguide and are, at the same time,
magnetically contiguous with the spin waveguide. This results in a 10 fold
increase in spin wave amplitude. However, the tube geometry distorts the
magnetic field near the spin waveguide and relatively high biasing magnetic
fields are required to establish well defined spin waves. Only the lowest
(uniform) spin wave mode is excited.Comment: 3 pages, 3 figure
A step toward a common measure of organizational fairness
The paper examines dimensions of organizational justice construct in a public sector context, utilizing an organizational justice measure developed and validated by Colquitt (2001). The present study substantiates the existing claims about the independence of interactional justice and the division of interactional justice into interpersonal and informational justice. The present investigation also contributes to the justice literature by providing evidence of a new factor, which is called procedural voice justice to reflect the possible association with the concept of voice effect. Although voice has been examined extensively in the justice research as an antecedent of procedural justice, little is known about if and how voice might integrate into procedural justice construct. The study proposes that future justice research further investigate dimensionality of organisational justice and aspire to developing a common measure of the justice construct.<br /
The Language and Labelling Used by University Students When Discussing Mental Health
This study aimed to explore University students’ understandings of mental health issues, mental health labels, and their attitudes towards these concepts. Five participants (four women aged 18-20, and one 24-year-old man) discussed in a focus group aspects of their childhood that they considered had affected their attitudes towards mental health and labelling. The three themes produced by inductive thematic analysis were ‘the language and context of labelling’, ‘stereotypes and social stigma’, and ‘personal experiences’. Findings have important implications for school nurses who work in primary schools, and who need to be aware of language use
Broadband Optical Serrodyne Frequency Shifting
We demonstrate serrodyne frequency shifting of light from 200 MHz to 1.2 GHz
with an efficiency of better than 60 percent. The frequency shift is imparted
by an electro-optic phase modulator driven by a high-frequency, high-fidelity
sawtooth waveform that is passively generated by a commercially available
Non-Linear Transmission Line (NLTL). We also implement a push-pull
configuration using two serrodyne-driven phase modulators allowing for
continuous tuning between -1.6 GHz and +1.6 GHz. Compared to competing
technologies, this technique is simple and robust, and offers the largest
available tuning range in this frequency band.Comment: 3 pages, 4 figure
Phase II study of docetaxel in combination with epirubicin and protracted venous infusion 5-fluorouracil (ETF) in patients with recurrent or metastatic breast cancer. A Yorkshire breast cancer research group study
This study was originally designed as a phase I/II study, with a dose escalation of docetaxel in combination with epirubicin 50 mg m⁻² and 5-fluorouracil (5-FU) 200 mg m⁻² day⁻¹. However, as dose escalation was not possible, the study is reported as a phase II study of the combination to assess response and toxicity. A total of 51 patients with locally advanced or metastatic breast cancer were treated on this phase II study, with doses of docetaxel 50 mg m⁻², epirubicin 50 mg m⁻² and infusional 5-FU 200 mg m⁻² day⁻¹ for 21 days. The main toxicity of this combination was neutropenia with 89% of patients having grade 3 and 4 neutropenia, and 39% of patients experiencing febrile neutropenia. Nonhaematological toxicity was mild. The overall response rate in the assessable patients was 64%, with median progression-free survival of 38 weeks, and median survival of 70 weeks. The ETF regimen was found to be toxic, and it was not possible to escalate the dose of docetaxel above the first dose level. This regimen has therefore not been taken any further, but as a development of this a new study is ongoing, combining 3-weekly epirubicin, weekly docetaxel and capecitabine, days 1-14
Dispersion and spin wave "tunneling" in nano-structured magnetostatic spin waveguides
Magnetostatic spin wave dispersion and loss are measured in micron scale spin
wave-guides in ferromagnetic, metallic CoTaZr. Results are in good agreement
with model calculations of spin wave dispersion. The measured attenuation
lengths, of the order of 3um, are several of orders of magnitude shorter than
that predicted from eddy currents in these thin wires. Spin waves effectively
"tunnel" through air gaps, produced by focused ion beam etching, as large as
1.5 um.Comment: 3 pages, 5 figure
