Empowerment and intentions to resist future change: the moderating effect organization-based self-esteem

Nowadays, organizations face a constant need for adaptability, increasing the importance of change management. Our study focuses of how empowering leadership influences intentions to resist future changes, mediated by the effects of psychological and structural empowerment. From the responses of the two questionnaires (N1=230; Ntf=113), we found that empowering leadership fosters psychological and structural empowerment. Structural empowerment was the main driver in reducing intentions to resist future change when an employee has high organization-based self-esteem. Our findings add to the literature by examining how we can anticipate and manage change under an empowering context, building on social exchange and uncertainty reduction theories

Mechanisms for sustainable accountability : a case study of a nonprofit educational organization

A qualitative case study of the capacity to be accountable in one nonprofit intennediary educational organization yielded an emergent conceptual framework of four mechanisms: structural, governing, communicative, and educative mechanisms to build and sustain the capacity of accountability. Drawing attention to the purposeful creation of structures that support accountability, purposeful navigation of the complex matrix of accountability relationships, and purposeful transfer of knowledge to infonn future accountability, this study calls for mindfulness in practice in broader educational contexts. Protocols to pass on knowledge gained in building the four capacities reveal a new dimension of accountability: continuity. In this model, the educative mechanism is the life force that feeds the other three mechanisms to increase accountability and sustain it over time.

Working Children: their Agency and self-organization

In recent years, ‘agency’ has appeared in academic writings as a new way of referring to active involvement from below in development interventions. The concept of ‘agency’ starts from the assumption that people are actually agents themselves, continuously acting in and reacting to circumstances. In child labour activism, this concept has been applied to working children in the understanding that, in order to improve their working conditions, children should be organised in organizations that are exclusively for and (ideally) run by working children. This paper aims to evaluate the extent to which child labourers can become agents of change through their own organizations. The paper will draw on two studies carried out by the IREWOC foundation. In 2002 a study was undertaken in Bolivia to give practical meaning to the concept of child agency. Secondly, in 2004/2005 an investigation was carried out on the functioning and impact of children’s organizations in Peru, Bolivia and Brazil. The applied research methods were mainly anthropological and used participant observation, (semi-) informal interviews and group interviewing with working children, their parents and adult representatives of the working children’s organizations. Both investigations show that in focussing on children as active participants, the structural constraints under which children have to live also need to be highlighted. One needs to understand how material poverty, mental deprivation and disempowerment help to shape resilience and defiance, but also anger, distrust and marginalisation.

A structural analysis of M protein in coronavirus assembly and morphology

The M protein of coronavirus plays a central role in virus assembly, turning cellular membranes into workshops where virus and host factors come together to make new virus particles. We investigated how M structure and organization is related to virus shape and size using cryo-electron microscopy, tomography and statistical analysis. We present evidence that suggests M can adopt two conformations and that membrane curvature is regulated by one M conformer. Elongated M protein is associated with rigidity, clusters of spikes and a relatively narrow range of membrane curvature. In contrast, compact M protein is associated with flexibility and low spike density. Analysis of several types of virus-like particles and virions revealed that S protein, N protein and genomic RNA each help to regulate virion size and variation, presumably through interactions with M. These findings provide insight into how M protein functions to promote virus assembly.

Electro-optical properties of liquid crystal copolymers and their relationship to structural order

A range of side chain liquid crystal copolymers have been prepared using mesogenic and non-mesogenic units. It is found that high levels of the non-mesogenic moieties may be introduced without completely disrupting the organization of the liquid crystal phase. Incorporation of this comonomer causes a marked reduction in the glass transition temperature (Tg), presumably as a result of enhanced backbone mobility and a corresponding lowering of the nematic transition temperature, thereby restricting the temperature range for stability of the liquid crystal phase. The effect of the interactions between the various components of these side-chain polymers on their electro-optic responses is described. Infrared (i.r.) dichroism measurements have been made to determine the order parameters of the liquid crystalline side-chain polymers. By identifying a certain band (CN stretching) in the i.r. absorption spectrum, the order parameter of the mesogenic groups can be obtained. The temperature and composition dependence of the observed order parameter are related to the liquid crystal phase transitions and to the electro-optic response. It is found that the introduction of the non-mesogenic units into the polymer chain lowers the threshold voltage of the electro-optic response over and above that due to the reduction in the order parameter. The dynamic electro-optic responses are dominated by the temperature-dependent viscosity and evidence is presented for relaxation processes involving the polymer backbone which are on a time scale greater than that for the mesogenic side-chain units.

Extracting quantitative structural parameters for disordered polymers from neutron scattering data

The organization of non-crystalline polymeric materials at a local level, namely on a spatial scale between a few and 100 a, is still unclear in many respects. The determination of the local structure in terms of the configuration and conformation of the polymer chain and of the packing characteristics of the chain in the bulk material represents a challenging problem. Data from wide-angle diffraction experiments are very difficult to interpret due to the very large amount of information that they carry, that is the large number of correlations present in the diffraction patterns.We describe new approaches that permit a detailed analysis of the complex neutron diffraction patterns characterizing polymer melts and glasses. The coupling of different computer modelling strategies with neutron scattering data over a wide Q range allows the extraction of detailed quantitative information on the structural arrangements of the materials of interest. Proceeding from modelling routes as diverse as force field calculations, single-chain modelling and reverse Monte Carlo, we show the successes and pitfalls of each approach in describing model systems, which illustrate the need to attack the data analysis problem simultaneously from several fronts.

Structural spoilers or structural supports? Unionism and the strategic integration of HR functions

The strategic integration of the human resource (HR) function is regarded as crucial in the literature on (strategic) human resource management ((S)HRM). Evidence on the contextual or structural influences on this integration is, however, limited. The structural implications of unionism are particularly intriguing given the evolution of study of the employment relationship. Pluralism is typically seen as antithetical to SHRM, and unions as an impediment to the strategic integration of HR functions, but there are also suggestions in the literature that unionism might facilitate the strategic integration of HR. This paper deploys large-scale international survey evidence to examine the organization-level influence of unionism on this strategic integration, allowing for other established and plausible influences. The analysis reveals that exceptionally, where the organization-level role of unions is particularly contested, unionism does impede the strategic integration of HR. However, it is the predominance of the facilitation of the strategic integration of HR by unionism which is most remarkable.

Electrical, optical, and structural studies of shallow-buried Au-polymethylmethacrylate composite films formed by very low energy ion implantation

The authors present here a summary of their investigations of ultrathin films formed by gold nanoclusters embedded in polymethylmethacrylate polymer. The clusters are formed from the self-organization of subplantated gold ions in the polymer. The source of the low energy ion stream used for the subplantation is a unidirectionally drifting gold plasma created by a magnetically filtered vacuum arc plasma gun. The material properties change according to subplantation dose, including nanocluster sizes and agglomeration state and, consequently also the material electrical behavior and optical activity. They have investigated the composite experimentally and by computer simulation in order to better understand the self-organization and the properties of the material. They present here the results of conductivity measurements and percolation behavior, dynamic TRIM simulations, surface plasmon resonance activity, transmission electron microscopy, small angle x-ray scattering, atomic force microscopy, and scanning tunneling microscopy.

A structure-dynamic approach to cortical organization: Number of paths and accessibility

A structure-dynamic approach to cortical systems is reported which is based on the number of paths and the accessibility of each node. The latter measurement is obtained by performing self-avoiding random walks in the respective networks, so as to simulate dynamics, and then calculating the entropies of the transition probabilities for walks starting from each node. Cortical networks of three species, namely cat, macaque and humans, are studied considering structural and dynamical aspects. It is verified that the human cortical network presents the highest accessibility and number of paths (in terms of z-scores). The correlation between the number of paths and accessibility is also investigated as a mean to quantify the level of independence between paths connecting pairs of nodes in cortical networks. By comparing the cortical networks of cat, macaque and humans, it is verified that the human cortical network tends to present the largest number of independent paths of length larger than four. These results suggest that the human cortical network is potentially the most resilient to brain injures. (C) 2009 Elsevier B.V. All rights reserved.

Floristic and structural characteristics of a coastal heathland exhibiting symptoms of Phytophthora cinnamomi infestation in the eastern Otway Ranges, Victoria

The floristics and structure of heathland vegetation exhibiting symptoms of Phytophthora cinnamomi Rands infestation was assessed at two sites in heathlands at Anglesea, Victoria. There were significant effects in both floristics and structure. Thirteen heathland species were significantly less abundant in diseased areas and 23 species were more abundant. Diseased (infested) vegetation, when compared with non-diseased areas, had less cover of Xanthorrhoea australis and shrub species and a greater cover of sedges, grasses and open ground. Structural differences were observed between heights 0 and 0.6 m, with a decline in cover recorded in diseased vegetation. Non-metric multidimensional scaling ordination of the floristic data showed a clear separation of diseased and non-diseased vegetation and that changes in floristic composition post-infestation were similar at both sites. Although there was some evidence of regeneration of X. australis, the recovery capacity of other susceptible species at Anglesea is unknown. The long-term consequences of loss of species and structure in the eastern Otways mean that the vegetation is unlikely to return to former status, especially if the pathogen continues to reinfect.

Subtle sexism : re-informing intergroup bias and regulating emotion in an Australian police organization

From a liberal feminist perspective, we argue that gender can both inform and should continue to be informed by social identity studies in efforts to understand and manage subtle sexism in contemporary workplaces. We investigated the presence of a form of subtle sexism, affective aversive sexism, in an Australian male-dominated organization: a police force. To do this we surveyed 159 policemen and examined relationships between individual emotional experience, emotional intensity and emotion regulation. Results indicated that, in a subtle display of intergroup bias, policemen experienced both higher positive and higher negative emotions in the presence of other policemen than of policewomen who, we argue, may be less central in the men's identities and relationships at work. Implications for research, training, and emotion management in the workplace are discussed and it is suggested that liberal feminist research can contribute much to understanding the dynamics that reproduce structural segregation in the workplace.

Australia and Japan in the South Pacific island countries : a general appraisal through the concepts of structural power

This study examines several specific fields of activity of Australia and Japan in the areas of security, production, finance, development assistance, information, education and regional organization. Using the concept of structural power, it observes the sources of Australian and Japanese strenght in the region, the growing imbalance in the bilateral Australia-Japan relationship, and also the coexistence of affinities and differences in the development opportunities opened to the South Pacific Island Countries.

Using strategic philanthropy to improve heritage tourist sites on the Gallipoli Peninsula, Turkey : community perceptions of changing quality of life and of the sponsoring organization

This paper examines the “Respect for History” project on Turkey's Gallipoli Peninsula sponsored by a Turkish oil company, OPET. The project sought to enhance and protect the cultural and historical experiences of tourists visiting Gallipoli, and to bring direct and indirect benefits to local communities through enhancing tourism-related business opportunities and improving community infrastructure. This research investigates the project's impact on residents’ perceived social and economic wellbeing, using a quality of life framework, and also ascertains residents’ views of the sponsoring firm. The context illustrates key differences between pure philanthropy and strategic philanthropy; the latter defined as doing good by purposefully achieving corporate and civic benefits. The role of strategic philanthropy as a sustainable tourism development tool, and its impact on tourism governance, are considered. Data were collected from 674 residents on the Turkish Gallipoli Peninsula in areas impacted by OPET's investment program. The results, using structural equation modelling (SEM), identify that respondents generally believe that both their economic and social quality of life have improved. This, in turn, has positively influenced respondents’ views of the sponsoring organization. The concept of strategic philanthropy appears valuable as a private sector, non-tourism, sustainable tourism development tool in some circumstances.

The Influence of water and metal salt on the transport and structural properties of 1-Octyl-3-methylimidazolium Chloride

The addition of diluents to ionic liquids (ILs) has recently been shown to enhance the transport properties of ILs. In the context of electrolyte design, this enhancement allows the realisation of IL-based electrolytes for metal-air batteries and other storage devices. It is likely that diluent addition not only impacts the viscosity of the IL, but also the ion-ion interactions and structure. Here, we investigate the nano-structured 1-methyl-3-octylimidazolium chloride (OMImCl) with varying water concentrations in the presence of two metal salts, zinc chloride and magnesium chloride. We find that the choice of metal salt has a significant impact on the structure and transport properties of the system; this is explained by the water structuring and destructing properties of the metal salt.
