Embodied energy in buildings : wood versus concrete - reply to Börjesson and Gustavsson

We analyse the wood and concrete designs of the Wälludden building described by Börjesson et al. (Energy Policy 28 (2000) 575) in terms of their embodied energy, employing an environmentally extended input–output framework in a tiered hybrid life-cycle assessment, and in a structural path analysis. We illustrate the complexity of the inter-industry supply chains underlying the upstream energy requirements for the building options, and demonstrate that higher-order inputs are difficult to capture in a conventional process analysis. Our calculations show that Börjesson and Gustavsson's estimates of energy requirements and greenhouse gas emissions are underestimated by a factor of about 2, and that corresponding greenhouse gas balances are positive at about 30 t C-eq. Nevertheless, Börjesson and Gustavsson's general result—the concrete-framed building causing higher emissions—still holds.

Hierarchical relationship between values, lifestyles, possessions and food consumption among Beijing adult population

A representative sample (N=801) of the Beijing adult population was used to empirically test and validate a proposed hierarchical model of relationships between values, lifestyles, possessions and food consumption. The theoretical contribution of the present study is the development and an empirically supported paradigm, which explains consumers' consumption behaviour. A further outcome is the substantiation of a pathway model involving hierarchical relationship between values, lifestyle, and demographic variables on material possessions and food consumption.

How can managers reduce employee intention to quit?

This paper reports on an investigation of the variables that may be predictive of intentions to leave a job, and tests a model that includes mediating variables. A total of 173 retail salespeople completed questionnaires measuring commitment to the organization for which they worked, job satisfaction, stress, supervisor support, locus of control, self-esteem, the perceived stressors in the job and their intention to quit. Path analysis was used to test the relationships hypothesized in the model. The majority of hypotheses were supported, with the variables included accounting for 52 per cent of the variance in intention to quit. Emotional support from supervisors and self-esteem mediated the impact of stressors on stress reactions, job satisfaction, commitment to the organization and intention to quit. It is suggested that to ameliorate intention to quit and in turn reduce turnover, managers need to actively monitor workloads, and the relationships between supervisors and subordinates in order to reduce and manage stress. Managers also need to monitor both the extrinsic and intrinsic sources of job satisfaction available to employees. These activities could assist in maintaining and increasing job satisfaction and commitment to the organization.

Same strategic HRM issues predict performance in both for-profit and non-profit organizations in a key knowledge-intensive industry

This paper examines the adoption of strategic human resource management (HRM) by for-profit and non-profit knowledge-intensive health services (HS) organisations in Australia. Survey data collected from senior executives is used to test the relationships between a strategic HRM model and firm performance. Path analysis found that, irrespective of whether for-profit or non-profit, adopting strategic HRM could increase organisational performance. Strategic HRM could be achieved through the cultivation of an external orientation to customers’ demands and an internal orientation highlighting commitment to employees. Public and non-profit organisations in the HS industry facing or undergoing health sector reform need to be aware of both of these orientations in order to adopt strategic HRM and improve their performance.

Strategic HRM in for-profit and non-profit organizations in a knowledge-intensive industry

This article examines the adoption of strategic Human Resource Management (HRM) by for-profit and non-profit knowledge-intensive health services (HS) organizations in the Australian context. Survey data collected from senior executives are used to test the relationships between a strategic HRM model and firm performance. Path analysis found that for HS firms, irrespective of whether for-profit or non-profit, adopting strategic HRM could increase organizational performance. Strategic HRM could be achieved through the cultivation of an external orientation to customers' demands and a commitment to employees. Building an external orientation with internal structural dimensions such as commitment to employees, allows HS organizations to develop a strategic HRM approach with human capital-enhancing HRM practices. Public and non-profit organizations in the HS industry facing or undergoing health sector reform need to be aware of both of these orientations in order to adopt strategic HRM and improve their performance.

Investigation of the effects of microcomputers on the work of professional accountants

Information technology research over the past two decades suggests that the installation and use of computers fundamentally affects the structure and function of organisations and, m particular, the workers in these organizations. Following the release of the IBM Personal Computer in 1982, microcomputers have become an integral part of most work environments. The accounting services industry, in particular, has felt the impact of this ‘microcomputer revolution’. In Big Six accounting firms, there is almost one microcomputer for each professional accountant employed, Notwithstanding this, little research has been done on the effect of microcomputers on the work outcomes of professional accountants working in these firms. This study addresses this issue. It assesses, in an organisational setting, how accountant’ perceptions of ease of use and usefulness of microcomputers act on their computer anxieties, microcomputer attitudes and use to affect their job satisfaction and job performance. The research also examines how different types of human-computer interfaces affect the relationships between accountants' beliefs about microcomputer utility and ease of use, computer anxiety, microcomputer attitudes and microcomputer use. To attain this research objective, a conceptual model was first developed, The model indicates that work outcomes (job satisfaction and job performance) of professional accountants using microcomputers are influenced by users' perceptions of ease of use and usefulness of microcomputers via paths through (a) the level of computer anxiety experienced by users, (b) the general attitude of users toward using microcomputers, and (c) the extent to which microcomputers are used by individuals. Empirically testable propositions were derived from the model to test the postulated relationships between these constructs. The study also tested whether or not users of different human-computer interfaces reacted differently to the perceptions and anxieties they hold about microcomputers and their use in the workplace. It was argued that users of graphical interfaces, because of the characteristics of those interfaces, react differently to their perceptions and anxieties about microcomputers compared with users of command-line (or textual-based) interfaces. A passive-observational study in a field setting was used to test the model and the research propositions. Data was collected from 164 professional accountants working in a Big Six accounting firm in a metropolitan city in Australia. Structural equation modelling techniques were used to test the, hypothesised causal relationships between the components comprising the general research model. Path analysis and ordinary least squares regression was used to estimate the parameters of the model and analyse the data obtained. Multisample analysis (or stacked model analysis) using EQS was used to test the fit of the model to the data of the different human-computer interface groups and to estimate the parameters for the paths in those different groups. The results show that the research model is a good description of the data. The job satisfaction of professional accountants is directly affected by their attitude toward using microcomputers and by microcomputer use itself. However, job performance appears to be only directly affected by microcomputer attitudes. Microcomputer use does not directly affect job performance. Along with perceived ease of use and perceived usefulness, computer anxiety is shown to be an important determinant of attitudes toward using microcomputers - higher levels of computer anxiety negatively affect attitudes toward using microcomputers. Conversely, higher levels of perceived ease of use and perceived usefulness heighten individuals' positive attitudes toward using microcomputers. Perceived ease of use and perceived usefulness also indirectly affect microcomputer attitudes through their effect on computer anxiety. The results show that higher levels of perceived ease of use and perceived usefulness result in lower levels of computer anxiety. A surprising result from the study is that while perceived ease of use is shown to directly affect the level of microcomputer usage, perceived usefulness and attitude toward using microcomputers does not. The results of the multisample analysis confirm that the research model fits the stacked model and that the stacked model is a significantly better fit if specific parameters are allowed to vary between the two human-computer interface user groups. In general, these results confirm that an interaction exists between the type of human-computer interface (the variable providing the grouping) and the other variables in the model The results show a clear difference between the two groups in the way in which perceived ease of use and perceived usefulness affect microcomputer attitude. In the case of users of command-line interfaces, these variables appear to affect microcomputer attitude via an intervening variable, computer anxiety, whereas in the graphical interface user group the effect occurs directly. Related to this, the results show that perceived ease of use and perceived usefulness have a significant direct effect on computer anxiety in command-line interface users, but no effect at all for graphical interface users. Of the two exogenous variables only perceived ease of use, and that in the case of the command-line interface users, has a direct significant effect on extent of use of microcomputers. In summary, the research has contributed to the development of a theory of individual adjustment to information technology in the workplace. It identifies certain perceptions, anxieties and attitudes about microcomputers and shows how they may affect work outcomes such as job satisfaction and job performance. It also shows that microcomputer-interface types have a differential effect on some of the hypothesised relationships represented in the general model. Future replication studies could sample a broader cross-section of the microcomputer user community. Finally, the results should help Big Six accounting firms to maximise the benefits of microcomputer use by making them aware of how working with microcomputers affects job satisfaction and job performance.

Enhancing hotel managers’ organisational commitment : an investigation of the impact of structure, needfor achievement and participative budgeting

This study investigates the role of decentralised structure and managers’ need for achievement as antecedents of participative budgeting, and the impact of the concurrent relationships of all three preceding variables on organisational commitment. Ninety-one managers from the Australian hotel industry participated in the study and data were analysed using path analysis. Direct and positive relationships were found between the two antecedent variables: decentralised structure and managers’ need for achievement, and participative budgeting. Participative budgeting, in turn, was found to have a direct and positive relationship with organisational commitment. The results of the study have implications for the design of effective management control processes and for human resource management of hospitality organisations.

Attachment as a predictor of leadership and follower outcomes

Research has suggested that effective leadership, specifically the utilisation of transformational leadership behaviours, is heavily entrenched in a leader’s interpersonal skills. However, few studies have investigated the interpersonal factors that drive appropriate use of transformational and transactional leadership in leader-follower settings. Attachment theory provides a robust framework in which to chart the developmental precursors of effective leadership that underpin positive leader-follower relationships and potential organisational outcomes. In this study, 46 manager-non manager dyads recruited from a Victorian education institution, a national telecommunications company and a Victorian real-estate business (managers – Mean age = 48.5 years, SD = 7.78, non-managers – Mean age 43.92 years, SD = 8.72) took part in an online questionnaire. Participants completed measures of attachment, leadership behaviour and organisational citizenship behaviour. Path analysis revealed that manager’s attachment style significantly predicted follower ratings of transformational and transactional leadership behaviours. Additionally, follower ratings of leadership were associated with organisational citizenship behaviour. Thus, it is concluded that attachment theory provides a valid framework in which to understand follower perceptions of leadership behaviour and subsequent organisational outcomes. These findings are discussed within the context of attachment theory and the leadership literature.

Gaming maching addiction : the role of avoidance, accessibility and social support

Commonality in etiology and clinical expression plus high comorbidity between pathological gambling and substance use disorders suggest common underlying motives. It is important to understand common motivators and differentiating factors. An overarching framework of addiction was used to examine predictors of problem gambling in current electronic gaming machine (EGM) gamblers. Path analysis was used to examine the relationships between antecedent factors (stressors, coping habits, social support), gambling motivations (avoidance, accessibility, social) and gambling behavior. Three hundred and forty seven (229 females: M = 29.20 years, SD = 14.93; 118 males: M = 29.64 years, SD = 12.49) people participated. Consistent with stress, coping and addiction theory, situational life stressors and general avoidance coping were positively related to avoidance-motivated gambling. In turn, avoidance-motivated gambling was positively related to EGM gambling frequency and problems. Consistent with exposure theory, life stressors were positively related to accessibility-motivated gambling, and accessibility-motivated gambling was positively related to EGM gambling frequency and gambling problems. These findings are consistent with other addiction research and suggest avoidance-motivated gambling is part of a more generalized pattern of avoidance coping with relative accessibility to EGM gambling explaining its choice as a method of avoidance. Findings also showed social support acted as a direct protective factor in relation to gambling frequency and problems and indirectly via avoidance and accessibility gambling motivations. Finally, life stressors were positively related to socially motivated gambling but this motivation was not related to either social support or gambling behavior suggesting it has little direct influence on gambling problems.

Predicting landscape-genetic consequences of habitat loss, fragmentation and mobility for multiple species of woodland birds

Inference concerning the impact of habitat fragmentation on dispersal and gene flow is a key theme in landscape genetics. Recently, the ability of established approaches to identify reliably the differential effects of landscape structure (e.g. land-cover composition, remnant vegetation configuration and extent) on the mobility of organisms has been questioned. More explicit methods of predicting and testing for such effects must move beyond post hoc explanations for single landscapes and species. Here, we document a process for making a priori predictions, using existing spatial and ecological data and expert opinion, of the effects of landscape structure on genetic structure of multiple species across replicated landscape blocks. We compare the results of two common methods for estimating the influence of landscape structure on effective distance: least-cost path analysis and isolation-by-resistance. We present a series of alternative models of genetic connectivity in the study area, represented by different landscape resistance surfaces for calculating effective distance, and identify appropriate null models. The process is applied to ten species of sympatric woodland-dependant birds. For each species, we rank a priori the expectation of fit of genetic response to the models according to the expected response of birds to loss of structural connectivity and landscape-scale tree-cover. These rankings (our hypotheses) are presented for testing with empirical genetic data in a subsequent contribution. We propose that this replicated landscape, multi-species approach offers a robust method for identifying the likely effects of landscape fragmentation on dispersal.

The impact of guanxi on export performance: A study of New Zealand firms exporting to China

Broadly defined as interpersonal relationship in Chinese society, guanxi embodies several intricate and unique Chinese cultural values. Although more and more western business people are becoming increasingly aware of the importance of guanxi in doing business in China, its potential impacts on the performance of business are still not well understood by western business people. This paper uses path analysis to assess the impacts of guanxi on export performance of a sample of New Zealand firms exporting to China. The results show that guanxi variables significantly facilitate trade partnering, business negotiating, and problem solving and generally contributes positively to the overall export performance of firms.

Foreign environmental impacts on export performance A study of agribusiness firms exporting to Japan

Although a large body of literature exists on export performance, little attention has been given to how foreign environments impact on the performance of firms exporting to a particular market. This study examines how the business environment in Japan impacts on a sample of New Zealand agribusiness firms exporting to this market. Using path analysis with LISREL, the findings suggest that the foreign environment in Japan has a small but significant adverse impact on export performance. The results also show that exporters are able to mediate the adverse effects of the Japanese business environment on their overall export performance by formulating effective product, pricing, promotion and distribution strategies.

The power of Australian small accounting firms’ unethical exposure

Purpose– The purpose of this paper is to investigate small business owner/manager’s exposure to unethical behavior, and to examine the influence of unethical exposure on organizational intention to implement ethical policies and practices.

Design/methodology/approach– Using a sample of 209 Australian small accounting firms with a path analysis, this paper adopts a modified ethical decision-making model to test the relationship between exposure and personal attitudes toward unethical behavior, and the relationship between exposure and intentions to implement ethical policies and practices at firm level.

Findings– The results show that increased exposure to unethical behavior triggered stronger personal attitudes with small accounting firm owners/managers tending toward accepting unethical behavior. In contrast, at the firm level, more exposure to unethical behavior creates cautious overtones and motivates owners/managers to take action and implement more ethical policies, with the underlying aim of addressing serious ethical issues.

Research limitations/implications– The study tests the ethical decision-making model but focuses only on three constructs (i.e. exposure, attitude and response). The aim is to examine whether extensive exposure to unethical behavior would change personal attitudes toward accepting such behavior, and whether unethical exposure would trigger firm owner/managers to take action and address the ethical dilemma by establishing some ethical guidelines. Other important variables (such as subjective norm, personal locus of control) embedded in the ethical decision-making model should be included in future research.

Practical implications– The study draws attention to ethical dilemmas encountered by many small accounting professionals and their organizations. It addresses the importance of upholding the ethical standard and avoiding the extensive exposure to unethical behavior. It also emphasizes the needs for small businesses to establish some ethical policies and practices.

Originality/value– The paper is purposely set out to reduce the gap in studying how small accounting firms make decisions in implementing their ethical policies and practices to address the rampant ethical dilemma faced by their employees as a result of many corporate scandals and financial crises of the past decade. The results are particularly valuable for small accounting firm owners/managers. The findings also have educational and policy implications.

The influence of market orientation on innovation strategies

Purpose – The purpose of this paper is to examine the effects of market orientation on exploratory and exploitative innovation, and the moderating effects of family ownership on these relationships. Design/methodology/approach – This study utilizes multi-group path analysis and confirmatory factor analysis in LISREL on data from 228 firms in the Australian service sector. Findings – This study establishes that both customer and competitor innovation are positively related to exploitative and exploratory innovation. However, customer orientation does not lead to significantly stronger effects on exploitative innovation than on exploratory innovation, and competitor orientation does not lead to significantly stronger effects on exploratory innovation than on exploitative innovation. In addition, the study found that the relationship between customer orientation and exploratory innovation was stronger for family firms, while the relationships between competitor orientation and both exploratory and exploitative innovation were stronger for non-family firms. Research limitations/implications – The cross-sectional design is one weakness of this study. In addition, as firms in the present study came from the service sector the generalizability of the findings to other sectors of the economy need to be determined. Practical implications – These findings of this study highlight the need for managers to build a strong market orientation in order to promote innovation, and consider the effects of ownership structure on innovation strategies. Originality/value – This study is the first to measure the relative influence of customer and competitor orientation on a firm’s use of exploitative and exploratory innovation strategies.
