Exploring the role of relationship variables in predicting customer voice to a service worker

Customers’ perceptions of service workers’ trustworthiness and power, and their commitment to the service worker were investigated as possible determinants of the likelihood of customer voice directly to the service worker in the event of a service failure. Set in the context of hairdressing salons, it was found that hair stylists’ perceived trust (benevolence and credibility) and expert power were positively associated with clients’ intention to voice. By contrast, the level of coercive power hair stylists were perceived to have was negatively associated with intentions to voice. Hair stylists’ perceived benevolence was the strongest predictor of client voice.

Interobserver reproducibility of histopathologic prognostic variables in primary cutaneous melanomas

Background: The prognosis for patients with localized primary cutaneous melanoma is known to depend principally on tumor thickness, and to a lesser extent on ulcerative state and Clark level. We have recently found in an analysis of 3661 patients that tumor mitotic rate (TMR) is also an important prognostic parameter, ranking second only to tumor thickness. However, few studies have assessed the accuracy and reproducibility with which these features of a melanoma are recorded by histopathologists.
Aim: To assess interobserver reproducibility of major pathologic prognostic parameters in cutaneous melanoma.
Methods: Single hematoxylin and eosin-stained slides of 69 dermally invasive primary cutaneous melanomas were circulated among six pathologists with differing experience in the assessment of melanocytic tumors. The observers independently determined the tumor thickness, Clark level of invasion, ulcerative state, and TMR for each lesion. Intraclass correlation coefficients and kappa scores for multiple ratings per subject were calculated.
Results: The intraclass correlation coefficients were 0.96 for tumor thickness and 0.76 for TMR. The kappa scores were 0.83 for ulcerative state and 0.60 for Clark level. These results indicated excellent agreement among the pathologists for measurements of tumor thickness, ulcerative state, and TMR and fair to good agreement for Clark level.
Conclusions: Appropriately trained and experienced histopathologists can assess prognostically important features of melanomas accurately and reproducibly. Given our recent finding of the significance of TMR in determining prognosis, it is important that this feature be assessed by a standardized method and documented for all primary cutaneous melanomas.

The relationship between emotional state and other variables influencing successful reintegration of ex-prisoners

This study investigated the multiple, complex, dynamic and interactive variables influencing successful reintegration of ex-prisoners, with a particular focus on the role of emotional state in the reintegration process. This involved conduct of a survey to a large group of prisoners approaching release and subsequently following release from prisons in Victoria and Queensland. Participants were 101 adult prisoners who completed a pre-release questionnaire one month prior to their release that focused on prison-related variables, participant background, and anticipated conditions upon release. A post-release questionnaire was administered to the same participants at one to four weeks and three to four months post-release, focusing on the quality of life conditions experienced following release. As well, the Beck Depression Inventory, Beck Anxiety Inventory, and the State-Trait Anger Expression Inventory were completed at each interview. Of interest, was the level and degree of change in prisoner ratings of depression, anxiety, and anger at pre-release and extending over the post-release period. As well, the strength of relationship between emotional state and the main variables influencing reintegration was investigated; that is, the degree to which reintegration variables (such as social support, drug use, post-release program participation, rated health) are associated with depression, anxiety, and anger among ex-prisoners. The report commences with the description of an ecological model of community reintegration that enables the main variables that may influence reintegration of ex-prisoners to be easily conceptualised and understood. A review of the international and Australian literature relevant to community reintegration of ex-prisoners is then presented, consistent with this conceptual framework, with a specific emphasis on the role of emotional state in post-release outcomes for this group. In the second section, the study design and method are described, with the results presented in the third section. The fourth and final section of the report includes a discussion of the results, implications for reintegration theory, and practical implications for promoting successful reintegration of ex-prisoners.

Reflexive and critical views of leadership performance in corporate accomplishment : framework and illustration

Purpose – This paper intends to shed some light on the relationship between leadership performance and corporate accomplishment through the aid of complexity sciences. The objective is to describe leadership performance in corporate accomplishment using different teleological approaches.

Design/methodology/approach – The paper discusses the underlying criteria of the relationship between leadership performance and corporate accomplishment. Case illustration and narrative analogy are also provided.

Findings – The authors believe that the discussion highlights a potential downside of leadership performance in corporate accomplishment and its precision rarely highlighted in practice and literature.

Research limitations/implications – There is a reigning assumption in management practice that is based on the belief that a top-down approach of leadership performance in management and business practices is superior to the bottom-up approach. It proffers the assumed importance of strategic management issues, but neglects the knowledge, experience, competence and awareness inherent among employees at tactical and operational levels of business practices. It also proffers a mechanical view of employee performance and ignores the worth of the generation of ideas from subordinates in management and business practices that contribute to corporate achievements. Furthermore, it neglects the fact that it is not possible to know the future nor it is predictable.

Practical implications – The paper contends that the importance of top management tends to be inflated in respect to corporate achievements in the management/leadership literature. It also contends that it should be questioned as to whether the top management of corporations are largely responsible for the corporate results on which they attempt to justify their salaries and other benefits. Furthermore, the paper contends that it also should be questioned as to what extent corporate accomplishment may be derived from the performance of the top management in organizations.

Originality/value – The paper strives to contribute to the ongoing discussion of leadership performance in corporate accomplishment in various ways. The principal contributions are: a set of teleological sub-processes of leadership performance and a case illustration and narrative analogies of teleological leadership performance patterns, in respect to corporate accomplishment in management and business practices. These contributions provide theoretical and managerial ideas and insights to anticipate and avoid deficient or erroneous grounds of leadership performance evaluation in corporate accomplishment.

Adopting reflexive capability in international briefing

Purpose – The aim of the paper is to investigate the architectural firm's role in the briefing process on international projects and to identify the strategies of successful firms to overcome barriers.

Design/methodology/approach – A model is developed based on a critique of briefing models and international design management theory. The development of a reflexive capability model borrows cultural theory concepts of capital and reflexivity. The model is based on maximizing reflexive capability through the management of social, cultural and intellectual capital. Two case studies of architectural firms identify barriers during the briefing process and strategies to overcome these barriers. Data collection involved 16 interviews with senior management and design team staff.

Findings – There are various barriers and strategies used to achieve success in the briefing process. However, the management of a firm's capital is key to successful briefing on international projects and is a characteristic of reflexive practice. Reflexivity is based in a positive interpretation of change, and a continual responsiveness to change by participants in a system. The study provides useful information on management of the design and briefing stages of international projects.

Research limitations/implications – The study is limited by the number of case studies used and the difficulty of generalisability of findings.

Practical implications – The research is that it provides useful information about how to approach constant change during briefing for the architects and clients who work on international projects.

Originality/value – The model is original and has value as it assists in explaining why some firms are more successful than others. The case studies provide new knowledge on international projects and the briefing process. The value of the paper is for the academic community, professionals in the built environment and clients involved in international projects.

Understanding travel behavior using demographic and socioeconomic variables as travel constraints

Samdahl and Jekubovich (1997) view constraints as a subset of reasons for not engaging in a particular behavior. There is limited empirical research on the role of demographic and socioeconomic variables as travel constraints. This study investigates the relationships between a wide range of short and long trip planning and travel behaviors and sociodemographic constraints comprised of age, income and life cycle.

This research uses data generated from a cross-sectional, self-completed survey on travel and tourism which was collected during 2003 and 2004 from 49,105 Australian respondents. This paper utilizes binomial regression to find that age, income and life stage have significant differential and interactive effects on travel behavior. The results show that sociodemographic variables act in different ways to constrain/free different types of travel behavior. Implications are provided for national and state based tourism authorities. There is a need to understand these phenomena. Current research is addressing these issues.

A reflexive capability model for sustainable e-business environments in construction supply chains

Despite the increasing significance of e-business worldwide and construction market leaders developing innovative e-business applications, the widespread uptake in the Australian construction industry is lagging. There has been considerable literature related to e-business adoption focusing on drivers and barriers to adoption. However, there has not been an investigation that has applied fundamental supply chain theory concepts. In this paper a reflexive capability model for the individual firm in relation to e-business is developed which relies upon merging economic and social practices through an industrial organization economic theoretical lens and social science theories of communication. The reflexive
capability model proposed within this paper describes a framework for theorization of the different degrees of e-business adoption exhibited by individual firm’s and accounts for social-cultural, organisational-structural, communicative and economic (market and supply
chain) barriers, influences and pressures to adopt e-business.The model is proposed for the construction supply chain to enable awareness, engagement and realization of e-business technology and achieve long term construction e-business sustainability.

How should we measure indigenous entrepreneurship? A search for explanatory variables

In Canada and elsewhere around the world Indigenous Peoples are struggling to rebuild their ‘nations’ and improve the socioeconomic circumstances of their people. We are embarking on a program of research in an effort to understand this phenomenon and to inform the process. In this paper we (i) explore the approach to development being adopted by Indigenous people in Canada; (ii) conduct a preliminary literature review; (iii) identify input indicators of entrepreneurship and business development capacity, process measures of development activity and an output indicator of development effectiveness and (v) identify the information available from secondary sources relating to these indicators and the gaps in information that will have to be filled by primary research.

Variables influencing the mathematics performance of first-year tertiary students : a case study

The need to understand which factors most strongly affect performance in first-year mathematics programs at Khon Kaen University (KKU), in North Eastern Thailand, provided the main focus of the study which is described. First-year mathematics students in the 1990-1991 academic year, from four KKU faculty groups (Medicine and Nursing, Agriculture, Science and Education, and Engineering) were involved in this study. Research literatures addressing variables which were likely to influence performance in early tertiary mathematical study, and variables associated with difficulties in learning mathematics at the transition from upper secondary school to tertiary studies, were reviewed. The first major aim of the study was to identify the variables which were good predictors of first-year mathematics performance at KKU. Results from stepwise multiple regression analyses indicated that the following predictor variables were statistically significant and entered the regression equations for most Faculty groups: School Mathematics Achievement, Self-Esteem, Study Habits in Mathematics, and Faculty of Study. Other predictor variables that sometimes entered regression equations (depending on the Faculty group) were Socio-Economic-Status, Mathematics Language Competence, Mathematics Confidence, Attitude Towards Mathematics, and Gender. Depending on Faculty group, the statistically significant variables accounted for between 11% and 74% of scores on fist-year KKU mathematics examinations. The predictor variables contributed much more to the variance of scores on first-semester mathematics examinations than to the variance of scores on second-semester mathematics examinations. It was also found that scores on the Direct Entry Examination Mathematics test (administered by KKU) and the School Mathematics Achievement test (developed and administered by the author) had stronger correlations with first-year KKU mathematics performance than did scores on the National Entry Examination Mathematics tests (administered by the Thai Ministry of University Affairs). Scores on the three pre-university mathematics achievement test instruments were better predictors of first-semester mathematics performance than of second-semester mathematics performance. It was found that the mean Mathematics Confidence of male students was statistically significantly higher than that of female students, but there were no statistically significant gender differences in Mathematics Misplaced Confidence. Only about 30% of the main sample ( 30% of the male and 30% of the female sample groups) had appropriate confidence in mathematics, that is, they thought their answers were correct when they were, in fact, correct, and they thought they were wrong when they were, in fact, incorrect. So far as Faculty performance differences were concerned, Engineering students had the highest Mathematics Confidence scores, followed by the Medicine and Nursing group of students and the Science and Education group students. Agriculture students had the lowest mean Mathematics Confidence score. No statistically significant differences occurred in Mathematics Misplaced Confidence between different Faculty groups. The second main aim of the study was to investigate why many first-year students experienced difficulties in coping with their mathematics units. A small group of senior secondary mathematics teachers, university mathematics lecturers, and first-year mathematics students were interviewed during the first semester of the 1990-1991 academic year. Interviews were conducted by the author according to a questionnaire format, and were aimed at identifying factors causing difficulty in the transition from senior secondary to university mathematical study. The analysis of the quantitative data together with the interview data indicated that the major sources of difficulty were associated with: (a) students' mathematical abilities; (b) curriculum content; (c) course organisation; (d) students' study habits; (e) instructional styles; and (f) assessment procedures. The results of the investigation are discussed in the light of the relevant literature and related research. The study concludes with recommendations which are addressed to mathematics teachers and education administrators in senior secondary schools in Thailand, to the Thai Ministry of Education, and to the KKU Department of Mathematics.

Developing reflexive capability for successful joint ventures between Australian and Malaysian property and construction professionals

Increasingly Malaysian property and construction firms are seeking to work internationally. Firms enter international markets through various strategies and typically property and construction professionals rely on developing various forms of cooperative and collaborative arrangements. The common modes of entry include international alliances, project joint ventures, partnerships, company joint ventures and large consortiums; which arise as a response to clients seeking expressions of interests from the international community or the firms seeking to internationalise approaching clients and/or potential host country partners. Increasingly project teams on international mega projects are composed of multiple key partners from different countries coming together to achieve a higher level of strategic flexibility. Establishing and maintaining local connections and business networks are therefore critical to ensure the success of exporting firms. This paper reports the findings of a project which explores factors affecting the performance of Malaysian property and construction professionals working internationally through effective joint ventures. The project seeks to develop a performance measurement framework to examine the extent to which Malaysian firms are developing sustainable business models internationally which adapt and respond to changing conditions. A generic framework was initially developed prior to this study through a grounded theory approach merging theory from internationalisation, design management and market knowledge literature followed by a case study empirical investigation and then further literature review based upon the themes which emerged from the case study analysis. A reflexive capability model for firms in managing both economic and non-economic capital; including social, cultural and intellectual capital was developed. This project seeks to build upon the reflexive model by adapting it to the unique contexts related to the specific geographic localities of exporting Malaysian firms. Specifically, the project explores the extent to which the performance measurement framework can be used to map capabilities Malaysian construction firms have and Which they need to develop in relation to developing and maintaining international collaborative partnerships. The preliminary results of one case study Malaysian architectural firm are discussed.

Variables associated with children's physical activity levels during recess : the A-CLASS project

Background
School recess provides a daily opportunity for children to engage in physically active behaviours. However, few studies have investigated what factors may influence children's physical activity levels in this context. Such information may be important in the development and implementation of recess interventions. The aim of this study was to investigate the association between a range of recess variables and children's sedentary, moderate and vigorous physical activity in this context.

Methods
One hundred and twenty-eight children (39% boys) aged 9-10 years old from 8 elementary schools had their physical activity levels observed during school recess using the System for Observing Children's Activity and Relationships during Play (SOCARP). Playground variables data were also collected at this time. Multilevel prediction models identified variables that were significantly associated with children's sedentary, moderate and vigorous physical activity during recess.

Results
Girls engaged in 13.8% more sedentary activity and 8.2% less vigorous activity than boys during recess. Children with no equipment provision during recess engaged in more sedentary activity and less moderate activity than children provided with equipment. In addition, as play space per child increased, sedentary activity decreased and vigorous activity increased. Temperature was a significant negatively associated with vigorous activity.

Conclusions
Modifiable and unmodifiable factors were associated with children's sedentary, moderate and vigorous physical activity during recess. Providing portable equipment and specifying areas for activities that dominate the elementary school playground during recess may be two approaches to increase recess physical activity levels, though further research is needed to evaluate the short and long-term impact of such strategies.
