Water quality is a key concern in the current global environment, with the need to promote practices that help to protect water quality, such as riparian zone management, being paramount. The present study used the theory of planned behaviour as a framework for understanding how beliefs influence decisions about riparian zone management. Respondents completed a survey that assessed their behavioural, normative, and control beliefs in relation to intentions to manage riparian zones on their property. The results of the study showed that, overall, landholders with strong intentions to manage their riparian zones differed significantly in terms of their beliefs compared to landholders who had weak intentions to manage their riparian zones. Strong intentions to manage riparian zones were associated with a favourable cost-benefit analysis, greater perceptions of normative support for the practice and lower perceptions of the extent to which barriers would impede management of riparian zones. It was also evident that willingness to comply with the recommendations of salient referents, beliefs about the benefits of riparian zone management and perceptions of the extent to which barriers would impede riparian zone management were most important for determining intentions to manage riparian zones. Implications for policy and extension practice are discussed. (c) 2005 Elsevier Ltd. All rights reserved.

The random switching of measurement bases is commonly assumed to be a necessary step of quantum key distribution protocols. In this paper we present a no-switching protocol and show that switching is not required for coherent-state continuous-variable quantum key distribution. Further, this protocol achieves higher information rates and a simpler experimental setup compared to previous protocols that rely on switching. We propose an optimal eavesdropping attack against this protocol, assuming individual Gaussian attacks. Finally, we investigate and compare the no-switching protocol applied to the original Bennett-Brassard 1984 scheme.

There is public unease about food-related issues including food additives, food poisoning bacteria and GM ingredients. The public wants evidence of no risks, but all regulators can ever offer is no evidence of risk or evidence of a very small risk. The situation is complex because experts and non-experts can perceive the same risk in vastly different ways. The way in which the food industry manages crises and communicates risks will determine the public acceptance and success of new technologies such as GM foods and nanomaterials. There is a need for the food industry (including regulators and scientific experts) to sharpen up their risk communication skills to ensure that technical innovations are accepted by consumers, and crises such as food recalls do not undermine the public's confidence in the food industry. The AIFST has a key role to play in driving the risk communication process and allaying public unease about food-related issues.

Developmental speech disorder is accounted for by theories derived from psychology, psycholinguistics, linguistics and medicine, with researchers developing assessment protocols that reflect their theoretical perspective. How theory and data analyses lead to different therapy approaches, however, is sometimes unclear. Here, we present a case management plan for a 7 year old boy with unintelligible speech. Assessment data were analysed to address seven case management questions regarding need for intervention, service delivery, differential diagnosis, intervention goals, generalization of therapeutic gains, discharge criteria and evaluation of efficacy. Jarrod was diagnosed as having inconsistent speech disorder that required intervention. He pronounced 88% of words differently when asked to name each word in the 25 word inconsistency test of the Diagnostic Evaluation of Articulation and Phonology three times, each trial separated by another activity. Other standardized assessments supported the diagnosis of inconsistent speech disorder that, according to previous research, is associated with a deficit in phonological assembly. Core vocabulary intervention was chosen as the most appropriate therapy technique. Its nature and a possible protocol for implementation is described.

Tourism has had, and is continuing to have, a profound impact upon destinations, economically, environmentally and socially. The negative impacts of tourism have been attributed, among other things, to inadequate or non-existent planning frameworks for tourism development, and it has therefore been advocated that tourism planning is vital to offset some of these negative impacts. While several different approaches have been supported over the years, tourism planning based on the philosophies of sustainability has emerged as one ofthe most comprehensive approaches. However, two critical concepts have been identified as precursors to sustainable development: a strategic Qrientation towards tourism planning and enhanced levels of multiple stakeholder participation in the tourism planning process (Simpson 2001 ). While both strategic tourism planning and stakeholder participation and collaboration, have received considerable attention in the academic literature, there has been relatively little written about its practical application. However, the somewhat recent emergence of the strategic visioning concept as a destination planning tool may provide the necessary practical framework for incorporating stakeholder collaboration into destination strategic planning and management. This paper will provide a synthesis of the stakeholder collaboration, strategic planning and strategic visioning literatures, before conceptually examining the potential applicability._ of the strategic visioning process in achieving meaningful stakeholder participation and collaboration in destination planning.

The Internet of Things (IoT) consists of a worldwide “network of networks,” composed by billions of interconnected heterogeneous devices denoted as things or “Smart Objects” (SOs). Significant research efforts have been dedicated to port the experience gained in the design of the Internet to the IoT, with the goal of maximizing interoperability, using the Internet Protocol (IP) and designing specific protocols like the Constrained Application Protocol (CoAP), which have been widely accepted as drivers for the effective evolution of the IoT. This first wave of standardization can be considered successfully concluded and we can assume that communication with and between SOs is no longer an issue. At this time, to favor the widespread adoption of the IoT, it is crucial to provide mechanisms that facilitate IoT data management and the development of services enabling a real interaction with things. Several reference IoT scenarios have real-time or predictable latency requirements, dealing with billions of device collecting and sending an enormous quantity of data. These features create a new need for architectures specifically designed to handle this scenario, hear denoted as “Big Stream”. In this thesis a new Big Stream Listener-based Graph architecture is proposed. Another important step, is to build more applications around the Web model, bringing about the Web of Things (WoT). As several IoT testbeds have been focused on evaluating lower-layer communication aspects, this thesis proposes a new WoT Testbed aiming at allowing developers to work with a high level of abstraction, without worrying about low-level details. Finally, an innovative SOs-driven User Interface (UI) generation paradigm for mobile applications in heterogeneous IoT networks is proposed, to simplify interactions between users and things.

Purpose: The purpose of the paper is to examine the kind of HRM practices being implemented by overseas firms in their Indian subsidiaries and also to analyze the linkage between HRM practices and organizational performance. Design/methodology/approach: The paper utilizes a mixture of both quantitative and qualitative techniques via personal interviews in 76 subsidiaries. Findings: The results show that while the introduction of HRM practices from the foreign parent organization is negatively associated with performance, local adaption of HRM practices is positively related with the performance of foreign firms operating in India. Research limitations/implications: The main limitations include data being collected by only one respondent from each firm, and the relatively small sample size. Practical implications: The key message for practitioners is that HRM systems do improve organizational performance in the Indian subsidiaries of foreign firms, and an emphasis on the localization of HRM practices can further contribute in this regard. Originality/value: This is perhaps the very first investigation of its kind in the Indian context. © Emerald Group Publishing Limited.

Purpose: The business process outsourcing (BPO) industry in India is evolving rapidly, and one of the key characteristics of this industry is the emergence of high-end services offered by knowledge processing outsourcing (KPO) organizations. These organizations are set to grow at a tremendous pace. Given the people-intensive nature of this industry, efficient employee management is bound to play a critical role. The literature lacks studies offering insights into the HR challenges involved and the ways in which they are addressed by KPOs. The purpose of this paper is to attempt to fill this gap by presenting findings from an in-depth case study of a KPO organization. Design/methodology/ approach: To achieve the research objective we adopted an in-depth case study approach. The research setting was that of a KPO organization in India, which specialises in offering complex analytics, accounting and support services to the real estate and financial services industries. Findings: The results of this study highlight the differences in the nature of work characteristics in such organizations as compared to call centres. The study also highlights some of the key people management challenges that these organizations face like attracting and retaining talent. The case company adopts formal, structured, transparent and innovative human resource practices. The study also highlights that such enlightened human resource practices stand on the foundations laid by an open work environment and facilitative leadership. Research limitations/implications: One of the key limitations is that the analysis is based on primary data from a single case study and only 18 interviews. The analysis contributes to the fields of KPO, HRM and India and has key messages for policy makers. Originality/value: The literature on outsourcing has in general focused on call centres established in the developed world. However, the booming BPO industry in India is also beginning to offer high-end services, which are far above the typical call centres. These KPOs and their people management challenges are relatively unexplored territories in the literature. By conducting this study in an emerging market (India) and focusing on people-related challenges in KPOs, this study attempts to provide a fresh perspective to the extant BPO literature. © Emerald Group Publishing Limited.

This study compares human resource management (HRM) practices in Indian public- and private-sector organizations. The investigation is based on a questionnaire survey of 137 large manufacturing firms (public sector = 81: private sector = 56). The key areas of analysis include the structure of human resource (HR) department, the role of HR function in corporate change, recruitment and selection, pay and benefits, training and development, employee relations and emphasis on key HRM strategies. Internal labour markets (ILMs) are used to make the comparative analysis. The statistical results show a number of similarities and differences in the HRM systems of Indian public-and private-sector organizations. Against the established notion, the results of this study reveal that the gap between Indian private- and public-sector HRM practices is not very significant. Moreover, in a few HR functional areas (for example, compensation and training and development), Indian private-sector firms have adopted a more rational approach than their public-sector counterparts. © 2004 Taylor and Francis Ltd.
