DURING the last few years a programme of creep tests under general stress systems at high temperatures has been carried out at the N.P.L., using four metallic alloys which were chosen as being representative of basic groups of materials used in practice in machinery operating at high temperatures. This work, it was hoped, would fulfil, at least partly, the great need for experimental data in this field, as opposed to the comparative abundance of theoretical work available, and also enable a critical examination of the merits of this theoretical work to be made. The materials chosen in order of examination were a cast 0–17 per cent carbon steel, an aluminium alloy (R.R. 59), a magnesium alloy (containing 2 per cent aluminium), and a nickel‐chromium alloy (Nimonic 75). Each material was tested at temperatures lying within the normal working range of the material in question. Thus the 0–17 per cent carbon steel was tested at 350, 450 and 550 dcg. C. (662, 842 and 1,022 deg. F.), the aluminium alloy at 150 and 200 deg. C. (302 and 392 dcg. F.), the magnesium alloy at 20 and 50 deg. C. (68 and 122 dcg. F.), and the nickel‐chromium alloy at 550 and 650 dcg. C. (1,022 and 1,202 deg. F.).

Examines varied empirical studies on downsizing which have revealed that, as a result of its aftermath, high percentages of companies have judged these efforts as unsuccessful. Corporate restructuring encompasses multiple forms of change, which are classified into three distinct categories: portfolio, financial and organizational. An analysis of the Freeman and Cameron theoretical framework on downsizing implementation processes is examined in terms of where the process occurs, during periods either of convergence and/or of reorientation, and the results associated with each approach. A case study of the Kansas Department of Health and Environment revealed that restructuring did not provide visible improvements in efficiency, economy and responsiveness. Cultural impact of this intervention revealed negative intergroup reactions, i.e. denial, dissatisfaction. An analysis of Richard Johnson’s model of the antecedents, processes and outcomes of downsizing revealed the impact upon strategy, productivity, human resources and finance. Interrelationships suggested diminished performances of firms which downsized without a lucid blueprint, adversely impacting upon these businesses. Finally, 30 recommendations are given for the human resource executive for effective downsizing, focusing upon: approach, involvement, leadership, communication, preparation, support, cost cutting, measurement, and implementation.

This article provides a critical review of four constructs-organizational identification, organizational commitment, occupational identification, and occupational commitment-to advance our understanding about how public sector employees from different occupations may become psychologically attached to their organizations. This review is intended to clarify previous inconsistencies as well as spark new interest among public administration researchers to examine sources and consequences of public employees’ organizational identification and commitment. This article also elucidates about how public sector employees’ attachment to their occupations may influence their attachment to their organizations. In that effort, this article reviews interrelationships among the four constructs. Finally, based on the patterns of connections observed, a future research program including seven testable research propositions is proposed.

The purpose of this paper is to model a nacre-like composite material, consisting of tablets and polyurea tablet/tablet interfaces, B₄C. This composite material is being considered in the construction of the so-called backing-plate, a layer within a multi-functional/multi-layer armor system.

Considering the basic functions of the backing-plate (i.e. to provide structural support for the ceramic-strike-face and to stop a high-velocity projectile and the accompanying fragments) in such an armor system, the composite-material architecture is optimized with respect to simultaneously achieving high flexural stiffness and high ballistic-penetration resistance. Flexural stiffness and penetration resistance, for a given architecture of the nacre-like composite material, are assessed using a series of transient non-linear dynamics finite-element analyses. The suitability of the optimized composite material for use in backing-plate applications is then evaluated by comparing its performance against that of the rolled homogeneous armor (RHA), a common choice for the backing-plate material.

The results obtained established: a trade-off between the requirements for a high flexural stiffness and a high ballistic-penetration resistance in the nacre-like composite material; and overall superiority of the subject composite material over the RHA when used in the construction of the backing-plate within multi-functional/multi-layer armor systems.

This study extends the authors previous research on nacre-mimetic armor to optimize the architecture of the armor with respect to its flexural stiffness and ballistic-penetration resistance, so that these properties could be increased over the levels attained in the current choice (RHA) for the backing layer of multi-functional/multi-layer armor.

BISPLINGHOFF has given a comparative graph showing the relative importance of the parameters of design at various Mach numbers. At Mach numbers above five, i.e. in the range of missile flight, creep becomes the critical design factor. Even though the time of flight of the missile is very short, and not enough to cause any considerable amount of creep, the deflexions caused will be enough to disturb the stability of compression members. Also the aerodynamic shape can be distorted with serious effects on the flow characteristics of the profile.

This study investigates the effects of corporate restructuring – scale and scope, on the financial performance and long‐term competitiveness during the 1980s in a data set of 107 manufacturing firms. Hypotheses were tested using Ordinary‐leastsquare (OLS) Regression model. Overall, this study found that: (1) corporate restructuring scope is inversely associated with firms’ performance, as expected; (2) the effects of restructuring scope on changes in competitiveness offer partial support for our hypotheses; (3) there was no support for the hypothesized relationships between restructuring scale and performance, and between restructuring scale and changes in competitiveness. Implications for future research in corporate restructuring are discussed.

The purpose of this study is to examine the influence of an urban folktale on the purchasing intentions and buying behaviour of the consumer. Specifically, it examines a rumour involving fashion designer Tommy Hilfiger, in which he purportedly made disparaging statements about African‐Americans. A survey of African‐American generation Xers revealed a relationship between the rumour and the decision to purchase Tommy Hilfiger clothing. Implications of the findings are discussed.

Environmental consequences increasingly influence management strategy and choice. The purpose of this paper is to investigate the effects on attention and investment of: incorporating environmental data into a balanced scorecard (BSC), called the sustainability balanced score card (SBSC) and the organization of environmental accounting information.

In a between‐participant design, participants (n ≈ 95) chose from among two investments using BSCs. Participants were randomly assigned to one of three conditions: no environmental data (control or BSC condition); environmental data embedded within the traditional BSC (four‐perspective SBSC); or environmental data added to a BSC as a standalone fifth perspective (five‐perspective SBSC).

Investment to achieve environmental stewardship objectives was greater with the four‐perspective SBSC than the traditional BSC. In addition, participants were most efficient, i.e. spent the least total time, and least time per data element examined, with the four‐perspective SBSC. Finally, the time spent examining, and decision weight given to, environmental data were unrelated.

Professional managers and accountants may have greater knowledge of environmental metrics than do students, who are the participants in this study; hence, the results may not generalize to higher knowledgeable professionals since their processing of environmental data may differ from the lower knowledge participants of this study.

The form (i.e. organization) of environmental accounting data changed the allocation of participants' attention while the presence of environmental accounting data changed participants' investments; hence, both the presence and form of environmental accounting information influenced decision making.

This study is among the first to show differing influences from both the presence and organization of environmental accounting data on attention and investment.

The purpose of this paper is to test the viability of the media relations framework, Mediating the Media model (Pang, 2010), and ascertains its relevance to practitioners in a changing media landscape in Singapore where social media is emerging as an alternative source of information tool.

In-depth interviews with 20 media relations practitioners who were former journalists. Practitioners with journalism experience were chosen as they perform better at media relations (Sallot and Johnson, 2006a; Sinaga and Callison, 2008).

The model posits two sets of influences, i.e. internal (journalist mindset, journalist routines and newsroom routines) and external (extra-media forces and media ideology) in media relations. Internal influences were found to be more prevalent than external influences and journalist mindset was the most pervasive factor influencing media relations.

Findings are based solely on interviews and some claims cannot be corroborated. As this is a qualitative study situated in one country, it is also not generalizable.

This study will serve useful insights for new practitioners to approach media relations in a holistic and systematic manner and for seasoned practitioners to re-evaluate their current media strategies.

This inaugural test found rigor in the model, and affords an in-depth understanding of the dynamics of journalist-practitioner relationships in a changing media landscape. It also presents an intriguing opportunity for the model to be applied to countries where the media industry operates under vastly different environments so as to ensure that the model stands up to scrutiny as it seeks to be positioned as a viable model for media relations.

The purpose of this paper is to explore treatment needs and factors contributing to engagement in substance use and sobriety among women with co-occurring substance use and major depressive disorders (MDDs) as they return to the community from prison.

The paper used qualitative methods to evaluate the perspectives of 15 women with co-occurring substance use and MDDs on the circumstances surrounding their relapse and recovery episodes following release from a US prison. Women were recruited in prison; qualitative data were collected using semi-structured interviews conducted after prison release and were analyzed using grounded theory analysis. Survey data from 39 participants supplemented qualitative findings.

Results indicated that relationship, emotion, and mental health factors influenced women's first post-prison substance use. Women attributed episodes of recovery to sober and social support, treatment, and building on recovery work done in prison. However, they described a need for comprehensive pre-release planning and post-release treatment that would address mental health, family, and housing/employment and more actively assist them in overcoming barriers to care.

In-prison and aftercare treatment should help depressed, substance using women prisoners reduce or manage negative affect, improve relationships, and obtain active and comprehensive transitional support.

Women with co-occurring mental health and substance use disorders are a high-risk population for negative post-release outcomes, but limited information exists regarding the processes by which they relapse or retain recovery after release from prison. Findings inform treatment and aftercare development efforts.
