This qualitative study explored how tobacco control policies are influenced and provided recommendations on how to advance tobacco control policy to benefit population health.

A novel fuzzy multi-objective framework to construct optimal prediction intervals for wind power forecast

The forecasting behavior of the high volatile and unpredictable wind power energy has always been a challenging issue in the power engineering area. In this regard, this paper proposes a new multi-objective framework based on fuzzy idea to construct optimal prediction intervals (Pis) to forecast wind power generation more sufficiently. The proposed method makes it possible to satisfy both the PI coverage probability (PICP) and PI normalized average width (PINAW), simultaneously. In order to model the stochastic and nonlinear behavior of the wind power samples, the idea of lower upper bound estimation (LUBE) method is used here. Regarding the optimization tool, an improved version of particle swam optimization (PSO) is proposed. In order to see the feasibility and satisfying performance of the proposed method, the practical data of a wind farm in Australia is used as the case study.

Flexible and rigid amine-functionalized microporous frameworks based on different secondary building units: supramolecular isomerism, selective CO₂ capture, and catalysis

We report the synthesis, structural characterization, and porous properties of two isomeric supramolecular complexes of ([Cd(NH₂—bdc)(bphz)_0.5 ]⋅DMF⋅H₂O}_n (NH₂ —bdc=2-aminobenzenedicarboxylic acid, bphz=1,2-bis(4-pyridylmethylene)hydrazine) composed of a mixed-ligand system. The first isomer, with a paddle-wheel-type Cd₂ (COO)₄ secondary building unit (SBU), is flexible in nature, whereas the other isomer has a rigid framework based on a μ-oxo-bridged Cd₂(μ-OCO)₂ SBU. Both frameworks are two-fold interpenetrated and the pore surface is decorated with pendant -NH₂ and =N—N= functional groups. Both the frameworks are nonporous to N₂ , revealed by the type II adsorption profiles. However, at 195 K, the first isomer shows an unusual double-step hysteretic CO₂ adsorption profile, whereas the second isomer shows a typical type I CO₂ profile. Moreover, at 195 K, both frameworks show excellent selectivity for CO₂ among other gases (N₂ , O₂ , H₂ , and Ar), which has been correlated to the specific interaction of CO₂ with the -NH₂ and =N—N= functionalized pore surface. DFT calculations for the oxo-bridged isomer unveiled that the -NH₂ group is the primary binding site for CO₂ . The high heat of CO₂ adsorption (ΔH_ads =37.7 kJ mol^-1) in the oxo-bridged isomer is realized by NH₂ ⋅⋅⋅CO₂ /aromatic π⋅⋅⋅CO₂ and cooperative CO₂ ⋅⋅⋅CO₂ interactions. Further, postsynthetic modification of the -NH₂ group into -NHCOCH₃ in the second isomer leads to a reduced CO₂ uptake with lower binding energy, which establishes the critical role of the -NH₂ group for CO₂ capture. The presence of basic -NH₂ sites in the oxo-bridged isomer was further exploited for efficient catalytic activity in a Knoevenagel condensation reaction.

A general collaborative framework for modeling and perceiving distributed network behavior

Collaborative Anomaly Detection (CAD) is an emerging field of network security in both academia and industry. It has attracted a lot of attention, due to the limitations of traditional fortress-style defense modes. Even though a number of pioneer studies have been conducted in this area, few of them concern about the universality issue. This work focuses on two aspects of it. First, a unified collaborative detection framework is developed based on network virtualization technology. Its purpose is to provide a generic approach that can be applied to designing specific schemes for various application scenarios and objectives. Second, a general behavior perception model is proposed for the unified framework based on hidden Markov random field. Spatial Markovianity is introduced to model the spatial context of distributed network behavior and stochastic interaction among interconnected nodes. Algorithms are derived for parameter estimation, forward prediction, backward smooth, and the normality evaluation of both global network situation and local behavior. Numerical experiments using extensive simulations and several real datasets are presented to validate the proposed solution. Performance-related issues and comparison with related works are discussed.

Are married couples happier in their relationships than cohabiting couples? Intimacy and relationship factors

This study was designed to examine the relationship between dyadic adjustment and intimacy, and to determine how this varies for different types of relationships between males and females, and for relationships of different duration. Eighty-seven heterosexual couples (10 dating, 21 living together, 56 married) participated in the study. The results demonstrated that there was a strong interrelationship between intimacy and dyadic adjustment for both males and females. Those in relationships of longer duration and married couples experienced higher levels of intimacy and relationship satisfaction than other couples. There was a general trend for married couples and those who were living together to have a higher level of agreement on their levels of intimacy and relationship adjustment than couples who were dating. The implication of these findings for obtaining a better understanding of the lifecycle of relationships is discussed.

Health Diaries in a Rural Australian Study

The authors designed a study around the use of health diaries comprising both open- and closed-ended questions and kept over a 16-week period by 118 rural and remote-dwelling families in Victoria, Australia. Participants documented their use of health services, episodes of illness, actions taken to keep healthy, and reflections on services and programs. In this article, the authors report on the health diary method. They discuss the qualitative ways in which the participants used their study involvement to enrich their lives: accessing health information and advice, furthering their concerns about rural health, and using the research process for social support. The authors discuss issues surrounding the rural and remote context of the study and the length of time over which the diaries were kept.

Trust and e-commerce: a study of consumer perceptions

Increasing use of the World Wide Web as a B2C commercial tool raises interest in understanding the key issues in building relationships with customers on the Internet. Trust is believed to be the key to these relationships. Given the differences between a virtual and a conventional marketplace, antecedents and consequences of trust merit re-examination. This research identifies a number of key factors related to trust in the B2C context and proposes a framework based on a series of underpinning relationships among these factors.

Multifactor productivity measures of construction sectors using OECD input-output database

This research develops a new productivity measurement framework for the construction sector in the light of an input-output table. Three group multifactor productivity indicators are formulated based on the multiplier concepts in the input-output analysis. This measurement framework focuses on the intro-industry flows of products and considers the direct and indirect effects of input and output. Moreover, this framework enables us to measure the multifactor productivity of a specific sector systematically. Historical analyses and international comparisons are carried out to indicate the differences of the productivity of the construction sectors in seven selected countries, using the newly published OECD input-output database. Research findings are expected to clarify how technological, organizational and political factors affect the productivity growth, enabling the policy makers, construction businesses and researchers to quantify the competitive ability of the construction sector.

More than just a transaction: conceptualising industry-based networks for virtual trading communities

This paper addresses the questions of why failure in industry-based networks has been so persistent and whether it is possible to avoid failure and achieve success in internet based markets [iMarketplaces]. A better explanation of implementation failures is important for both improved empirical outcomes and theory building. We construct a theoretical framework based on Bijker’s technology frame (1995) and a contextualization typology developed by Nowotny, Scott and Gibbons (2001). The framework helps us understand how industry-based networks function, why they fail and how we can apply the framework to assist better empirical outcomes. In this paper we apply our framework to Food Connect Australia, a vertically integrated marketplace, representative of the first wave of B2B markets. Sponsors of these iMarketplaces were quick to see and exploit the opportunities online access offered to bring together large numbers of buyers and sellers in new ways. However a lack of understanding of firstly, what represented true value in these networks and secondly, how to achieve buy-in at sustainable levels, meant that many of these first wave sites failed. Application of our framework reveals why there has been a radical shift from the trading role originally envisioned for these sites to the information hub model of the iMarketplace that industry is now being urged to adopt (Berryman and Heck, 2001).

Are we speaking the same language? Corporate perceptions of human rights responsibilities

Over the last several years, notions of corporate social responsibility and corporate responsibility for human rights have developed on several fronts, including under international human rights law, through voluntary initiatives and in the discourse and the reporting of the corporations themselves. But are all protagonists on all these fronts speaking the same language? Are these developments truly improving the realisation of human rights?
As one aspect of its three year Australian Research Council project examining the legal human rights responsibilities of multinational corporations, the Castan Centre for Human Rights Law set out to discover the perceptions that multinational corporations have of their own human rights responsibilities, the types of activities undertaken by corporations to fulfill those responsibilities and the appropriate extent, if any, of the imposition of legally binding human rights obligations on corporations.
While not setting out the formal findings of that empirical study, this paper reports on some interesting discoveries as to how corporations see their place in the human rights debate. It notes a divergence among corporations' views of the nature of human rights responsibility - whether an obligation or a benevolence - as well as its content. In considering whether corporations ought to have legally binding human rights obligations, a surprising number of corporations replied in the affirmative, citing reasons such as certainty in dealing with suppliers and instituting a level playing field against rogue operators.
However,  perhaps the most important finding is the different understandings of human rights as they relate to a corporation's operations. Agreement on potential reforms would be meaningless if they were not employed towards a commonly understood end. After examining the various responses of the corporations and the evidence they cited to support their contentions, the paper concludes that the various protagonists of human rights responsibility for corporations may be using the same words, but they are not yet speaking the same language.

Project quality management for small and medium enterprises (SMEs) in trade

Managing project quality is becoming focal issue in major enterprises as popular quality programs from International Standard Organization (ISO) such as ISO9000 certification processes gain momentum. Large organizations as well as small-medium enterprises (SMEs) seem to implement this program, albeit for varied reasons. In this paper, we have reported the findings from an action research project conducted in SMEs who are implementing quality management. The findings indicate that external pressures such as regulations, competition and perceived success - defined on their own parameters, may be the drivers and the certification does not necessarily result in better performance. We are in the process of developing a cost-effective guideline/framework - based on this research, for SMEs involved in the certification process. In addition, the results are aimed at informing academia as well as certification bodies of specific concerns with SMEs.

Tonic Sol-fa in contemporary choral music practice : a South African case study

The Tonic Sol-fa method of teaching choral singing was propagated throughout Britain during the nineteenth century with the dual objectives of enhancing Christian worship and achieving social reform. It was then imported to South Africa where it was introduced to indigenous people principally through Christian missionary activity and government schools. Although entirely of foreign origin, Tonic Sol-fa was so fully assimilated into African culture that it became effectively 'indigenised'. Due to its widespread use, it became the mainstay of community choral singing and may now be said to represent a significant exogenous aspect of present-day South African musical identity. However, there is little documentation regarding the type and extent of its use in contemporary choral music practice.

This paper will report on the use of Tonic Sol-fa in representative present-day choral music settings. Interview data collected from choir directors, trainers and teachers in Cape Town indicate that there is far from unanimous agreement on several aspects - in particular, the future of Tonic Sol-fa as a pedagogy and notational system. Improving educational opportunities for indigenous South Africans to undertake professional training in music are now threatening the traditional dominance of Tonic Sol-fa in indigenous culture. Nevertheless this research represents a useful case study of the continuing relevance of Tonic Sol-fa to an indigenous population who have 'made it their own' and developed a vibrant choral tradition which continues to both enrich and sustain their lives.

How well do ecosystem-based planning units represent different componenets of biodiversity?

There are many proposals for managing biodiversity by using surrogates, such as umbrella, indicator, focal, and flagship species. We use the term biodiversity management unit for any ecosystem-based classificatory scheme for managing biodiversity. The sufficiency of biodiversity management unit classification schemes depends upon (1) whether different biotic elements (e.g., trees, birds, reptiles) distinguish between biodiversity management units within a classification (i.e., coherence within classes}; and (2) whether different biotic elements agree upon similarities and dissimilarities among biodiversity management unit classes (i.e., conformance among classes). Recent evaluations suggest that biodiversity surrogates based on few or single taxa are not useful. Ecological vegetation classes are an ecosystem-based classification scheme used as one component for biodiversity management in Victoria, Australia. Here we evaluated the potential for ecological vegetation classes to be used as biodiversity management units in the box-ironbark ecosystem of central Victoria, Australia. Eighty sites distributed among 14 ecological vegetation classes were surveyed in the same ways for tree species, birds, mammals, reptiles, terrestrial invertebrates, and nocturnal flying insects. Habitat structure and geographic separations also were measured, which, with the biotic elements, are collectively referred to as variables. Less than half of the biotic element-ecological vegetation class pairings were coherent. Generalized Mantel tests were used to examine conformance among variables with respect to ecological vegetation classes. While most tests were not significant, birds, mammals, tree species, and habitat structure together showed significant agreement on the rating of similarities among ecological vegetation classes. In this system, use of ecological vegetation classes as biodiversity management units may account reasonably well for birds, mammals, and trees; but reptiles and invertebrates would not be accommodated. We conclude that surrogates will usually have to be augmented or developed as hierarchies to provide general representativeness.

Co-ordination of the discharge planning process in critical care

Aim and objectives: This article reports on the current discharge planning beliefs in relation to the co-ordination of the discharge planning process in the critical care environment in the health care system in the state of Victoria, Australia. As there is a paucity of previous studies examining discharge planning in critical care nursing knowledge about the phenomena is consequently limited. Background: The study reported here is part of a larger study exploring critical care nurses' perceptions and understanding of the discharge planning process in the health care system in the state of Victoria, Australia. While a number of different discharge planning models are reported in the literature there is no agreement on the most effective or the most efficient model. Design: An exploratory descriptive research design was used for this study. Methods: A total of 502 Victorian critical care nurses were approached to take part in the study. A total of 218 participants completed the survey, which represented a nett response rate of 43·4%. The data from the questionnaire were entered into the Statistical Package for Social Sciences (SPSS) Base 10.0. This allowed calculation of descriptive statistics and statistical analysis using chi-square test for goodness-of-fit.  Results: While just over half the participants reported that the discharge planning process in their unit was co-ordinated by a combination of personnel that included a nurse, just under half the participants believed that this was an appropriate model. Another key finding was of those participants who worked in critical care units using primary nursing, just over half responded that the bedside nurse/primary nurse co-ordinated the discharge planning process while just under half responded that a combination of health care team members, including a nurse, co-ordinated the process. Overall there was little support for the designated discharge planning nurse to co-ordinate the process. Conclusions: The findings presented here suggest critical care nurses need to examine who has the ultimate responsibility of co-ordinating the critical care patient's discharge plan irrespective of the nursing model employed within the critical care ward. There is the need to ensure that when discharge planning becomes everybody's responsibility it ultimately does not become no-one's responsibility. Relevance to clinical practice: If discharge planning practices are to be changed with the introduction of new discharge planning models in the critical care environment then it is important not only to know current practice but also the perceptions of critical care nurses in terms of who they believe should co-ordinate the discharge planning process.

Supporting user evaluation of IT security certification schemes

IT Security Certification is an increasingly important qualification for information technology (IT) professionals seeking employment in IT security. Yet currently there is a lack of rigorously developed approaches to support the evaluation and selection by key stakeholders of the most appropriate IT security certification scheme from among hundreds of vendor-neutral and vendor-specific schemes. This paper develops a framework based on categories, characteristics and criteria to support user evaluation and selection of an (IT) Security Certification scheme that satisfies user priorities and requirements. The paper illustrates the use of the framework to support an experienced IT Professional’s evaluation. Theoretical and practical implications of the framework and trial evaluation are discussed.
