Abstract

Purpose

The purpose of this paper is to apply the meshless method of fundamental solutions (MFS) to the two‐dimensional time‐dependent heat equation in order to locate an unknown internal inclusion.

Design/methodology/approach

The problem is formulated as an inverse geometric problem, using non‐invasive Dirichlet and Neumann exterior boundary data to find the internal boundary using a non‐linear least‐squares minimisation approach. The solver will be tested when locating a variety of internal formations.

Findings

The method implemented was proven to be both stable and reasonably accurate when data were contaminated with random noise.

Research limitations/implications

Owing to limited computational time, spatial resolution of internal boundaries may be lower than some similar case investigations.

Practical implications

This research will have practical implications to the modelling and monitoring of crystalline deposit formations within the nuclear industry, allowing development of future designs.

Originality/value

Similar work has been completed in regards to the steady state heat equation, however to the best of the authors' knowledge no previous work has been completed on a time‐dependent inverse inclusion problem relating to the heat equation, using the MFS. Preliminary results presented here will have value for possible future design and monitoring within the nuclear industry

Abstract

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Achieving the elimination of racial differences in test performance, as set forth in the No Child Left Behind Act of 2001 (NCLB), requires education policies that engage the reality that African American test performances are not only about race but also about gender and residential status. In an effort to inform education policymaking with research that explores race–gender and residential inequality, I assess the growth of reading gaps in school and non-school contexts using a national and city sample of children from the Early Childhood Longitudinal, Kindergarten Cohort 1998–1999. I found that inequality in test performances was greater in the city than elsewhere, and African American boys shoulder a disproportionate educational burden related to city residency and enrollment in city schools. Additionally, children in city neighborhoods – where drugs and burglary are big problems – experience large shortfalls in reading in school and non-school contexts. I conclude with a discussion of the study’s implications for future educational policy, practice, and research, especially NCLB, which mandates that public schools achieve parity among racial groups by the end of the 2013–2014 academic year.

Abstract

Virtually all research on organizational citizenship behavior (OCB) is rooted in a social exchange based view of citizenship performance. While we do not dispute the significant role exchange motives play in citizenship performance, we nevertheless see what amounts to a preoccupation with and over-reliance on social exchange processes in extant OCB theory. With the goals of improving the prediction of citizenship performance and advancing human resource management practice, we outline several new directions for OCB theory and research.

Abstract

Purpose

Despite the popularity of school “turnaround” and “portfolio district” management as solutions to low performance, there has been limited research on these strategies. The purpose of this paper is to address this gap by exploring the strategic case of Los Angeles Unified School District's Public School Choice Initiative (PSCI) which combined both of these reforms. It examines how core mechanisms of change played out in schools and communities during the first two years of implementation.

Design/methodology/approach

The paper draws on a mixed methods study, combining data from surveys, case studies, leader interviews, observations, and document review. It is guided by a conceptual framework grounded in research on school turnaround and portfolio districts, along with the district's implicit theory of change.

Findings

The paper finds early success in attracting diverse stakeholder participation, supporting plan development, and ensuring transparency. However, data also indicate difficulty establishing understanding and buy‐in, engaging parents and community, attracting sufficient supply of applicants, maintaining neutrality and the perception of fairness, and avoiding unintended consequences of competition – all of which weakened key mechanisms of change.

Research limitations/implications

Data from parent focus groups and school sites may not be representative of the entire population of parents and schools, and data come from a short period of time.

Practical implications

The paper finds that developing processes and procedures to support complex reform takes time and identifies roadblocks others may face when implementing school turnaround and portfolio management. The research suggests districts invest in ways to ensure neutrality and create a level playing field. It also indicates that leaders should anticipate challenges to engaging parents and community members, such as language and literacy barriers, and invest in the development of unbiased, high‐quality information and opportunities that include sufficient time and support to ensure understanding.

Originality/value

This paper begins to fill a gap in research on popular reform strategies for improving low‐performing schools.

Abstract

This article reviews the extensive history of dynamic performance research, with the goal of providing a clear picture of where the field has been, where it is now, and where it needs to go. Past research has established that job performance does indeed change, but the implications of this dynamism and the predictability of performance trends remain unresolved. Theories are available to help explain dynamic performance, and although far from providing an unambiguous understanding of the phenomenon, they offer direction for future theoretical development. Dynamic performance research does suffer from a number of methodological difficulties, but new techniques have emerged that present even more opportunities to advance knowledge in this area. From this review, I propose research questions to bridge the theoretical and methodological gaps of this area. Answering these questions can advance both research involving job performance prediction and our understanding of the effects of human resource interventions.

Abstract

We propose that off-the-job embeddedness (OTJE) be reconceptualized as a separate and distinct, albeit related, construct from job embeddedness. We conceptualize OTJE as the totality of outside-work forces which keep an individual bound to his/her current geographical area and argue that this construct includes important factors which do not fall under the umbrella of “community embeddedness.” Moreover, we propose that these outside-work forces may embed individuals in their jobs either directly or indirectly (through the perceived or expressed preferences of spouses, children, and extended family). This paper identifies the key components of OJTE, addresses the measurement of OTJE, explains the relationships between job embeddedness and OTJE (and their respective components), highlights how OTJE can either amplify or counteract the effects of job embeddedness, and illustrates the direct and indirect effects of OTJE on both work-related and personal outcomes.
