Values congruence: more salient to social networking than to fit

This developmental paper looks at the issue of values congruence and the extent to which it evidences fit (for example P-O, P-G, P-P fit) or is more salient when identifying a social network which might be a more relevant construct for employees in the workplace. It takes a brief look at the background to the interaction debate as a foundation for the argument that value congruence is key to building relationships between individuals. The debate is brought up to date with a discussion of Edwards and Cable’s 2009 paper which puts the case for the value in value congruence in determining employee behaviour. This paper, however, seeks to question the extent to which values congruence is more important to individuals at work in terms of their fit (on whatever level) or in terms of their social network (which might underpin a sense of ‘not misfitting’) which might be key for many employees. The paper goes on to consider the implications for fit research in the light of salience of social network theory

Target Localization Accuracy Gain in MIMO Radar Based Systems

This paper presents an analysis of target localization accuracy, attainable by the use of MIMO (Multiple-Input Multiple-Output) radar systems, configured with multiple transmit and receive sensors, widely distributed over a given area. The Cramer-Rao lower bound (CRLB) for target localization accuracy is developed for both coherent and non-coherent processing. Coherent processing requires a common phase reference for all transmit and receive sensors. The CRLB is shown to be inversely proportional to the signal effective bandwidth in the non-coherent case, but is approximately inversely proportional to the carrier frequency in the coherent case. We further prove that optimization over the sensors' positions lowers the CRLB by a factor equal to the product of the number of transmitting and receiving sensors. The best linear unbiased estimator (BLUE) is derived for the MIMO target localization problem. The BLUE's utility is in providing a closed form localization estimate that facilitates the analysis of the relations between sensors locations, target location, and localization accuracy. Geometric dilution of precision (GDOP) contours are used to map the relative performance accuracy for a given layout of radars over a given geographic area.Comment: 36 pages, 5 figures, submitted to IEEE Transaction on Information Theor

Book review of perspectives on organizational fit by Cheri Ostroff and Timothy A. Judge (Editors)

From the first moment you set your eyes on this book, you are aware that it is a serious endeavor. Edited by two of the most published people in the field and sporting an imposing black and lime green dust cover containing an image of a swarm of black skull-headed moths, it contains chapters written by virtually all of “the good and the great” of the field. A flick through the pages reveals hundreds of pages of narrow margins and dense typescript interspersed with equations and three-dimensional graphs. This is a book that demands attention

Book review of 'the people make the place: dynamic linkages between individuals and organizations edited by D. Brent Smith'

The People Make the Place is a festschrift celebrating the work of industrial/organizational psychologist Benjamin Schneider. It contains 11 specially written chapters each addressing a different element of Schneider’s work. The twelfth chapter, written by the honored scholar, summarizes the contributions and uses the opportunity to clarify many of the ideas surrounding attraction-selection-attrition (ASA) theory

Target localization in MIMO radar systems

MIMO (Multiple-Input Multiple-Output) radar systems employ multiple antennas to transmit multiple waveforms and engage in joint processing of the received echoes from the target. MIMO radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. Elements of MIMO radar have the ability to transmit diverse waveforms ranging from independent to fully correlated. MIMO radar offers a new paradigm for signal processing research. In this dissertation, target localization accuracy performance, attainable by the use of MIMO radar systems, configured with multiple transmit and receive sensors, widely distributed over an area, are studied. The Cramer-Rao lower bound (CRLB) for target localization accuracy is developed for both coherent and noncoherent processing. The CRLB is shown to be inversely proportional to the signal effective bandwidth in the noncoherent case, but is approximately inversely proportional to the carrier frequency in the coherent case. It is shown that optimization over the sensors\u27 positions lowers the CRLB by a factor equal to the product of the number of transmitting and receiving sensors. The best linear unbiased estimator (BLUE) is derived for the MIMO target localization problem. The BLUE\u27s utility is in providing a closed-form localization estimate that facilitates the analysis of the relations between sensors locations, target location, and localization accuracy. Geometric dilution of precision (GDOP) contours are used to map the relative performance accuracy for a given layout of radars over a given geographic area. Coherent processing advantage for target localization relies on time and phase synchronization between transmitting and receiving radars. An analysis of the sensitivity of the localization performance with respect to the variance of phase synchronization error is provided by deriving the hybrid CRLB. The single target case is extended to the evaluation of multiple target localization performance. Thus far, the analysis assumes a stationary target. Study of moving target tracking capabilities is offered through the use of the Bayesian CRLB for the estimation of both target location and velocity. Centralized and decentralized tracking algorithms, inherit to distributed MIMO radar architecture, are proposed and evaluated. It is shown that communication requirements and processing load may be reduced at a relatively low performance cost

South West Food Community: Understanding systemic change, and its associated challenges and successes, among food security projects

Objective: The South West Food Community (SWFC) project (2018) aimed to identify initiatives working to support food security in the South West region of Western Australia, and to enhance how these initiatives functioned as a system. The SWFC project used a Systemic Innovation Lab approach that, prior to this study, had not been evaluated. This evaluation aimed to: i) measure system transitions (changes) to initiatives; and ii) understand the challenges and successes associated with system transitions. Methods: SWFC initiative leaders (n=46) such as directors, managers or coordinators, volunteers or committee members were invited to participate in this evaluation. Fifteen stakeholders completed the telephone interviews (32% response rate). Results: Twenty‐five desirable changes in practice were observed. Challenge and success statements determined themes of ‘participation’ and ‘bureaucracy’. Participation sub‐themes included: limited time; poor initiative attendance; community support; organisational support; and effective partnerships. Bureaucracy sub‐themes included: regulation or policy requirements; limited resources; and funding opportunities. Conclusion: The Australian‐first SWFC project has the capacity to support region‐to‐region comparisons; this evaluation increases evidence for scaling to other regions. Implications for public health: This approach can be used to increase collaboration between initiatives, support resource‐sharing between organisations and enhance policies (at local government level) to support food security

Problems, policy and politics – perspectives of public health leaders on food insecurity and human rights in Australia

Background: To achieve zero hunger targets set within the United Nations’ Agenda 2030, high-income countries such as Australia must reconsider current efforts to improve food security. This study aimed to; explore perspectives from public health nutrition experts on the usefulness of drawing on the international human right to food, and associated mechanisms, to address food insecurity; identify potential roles of key stakeholders in Australia to implement a rights-based approach; and examine barriers and enablers to achieving the right to food in Australia. Methods: Qualitative in-depth interviews were conducted with key informants ( \u3e 10 years professional experience). Braun and Clarke’s (2006) six-phase approach to thematic analysis was employed to analyse data, using Kingdon’s multiple streams framework (1984) to examine interactive variables which affect policy-making processes. Results: Thirty interviews took place, with most participants representing academia (n = 16), majority had 10–14 years of experience (n = 12) and almost one quarter (n = 7) were in senior leadership roles. Participants believed that framing food insecurity as a human rights issue could be effective when communicating with some audiences, however alternative rhetoric is more popular and potentially more effective. Citizens, government, food industry, non-profit sector, research/tertiary and legal institutions were described as playing critical roles. Barriers to progress were identified as lack of awareness and acknowledgement of the problem, prioritisation of the private sector, lack of political will and domestic laws, and an inefficient/ineffective charitable food sector. Participants identified various enablers and opportunities for implementing a rights-based approach such as grass-roots advocacy efforts to raise awareness of the issue, integrating human rights into government frameworks and community projects and the political will to support action aligned with sustainable development. Conclusions: Human rights language and mechanisms have the potential to trigger genuine commitment to addressing food insecurity however should be used with caution. Australia’s public health workforce requires increased capacity to implement a human-rights approach and framing such efforts to align with sustainable development may achieve greater political action.
