Small-scale randomized controlled trials need more powerful methods of mediational analysis than the Baron-Kenny method

Objective: To devise more-effective physical activity interventions, the mediating mechanisms yielding behavioral change need to be identified. The Baron–Kenny method is most commonly used, but has low statistical power and may not identify mechanisms of behavioral change in small-to-medium size studies. More powerful statistical tests are available.
Study Design and Setting: Inactive adults (N = 52) were randomized to either a print or a print-plus-telephone intervention. Walking and exercise-related social support were assessed at baseline, after the intervention, and 4 weeks later. The Baron–Kenny and three alternative methods of mediational analysis (Freedman–Schatzkin; MacKinnon et al.; bootstrap method) were used to examine the effects of social support on initial behavior change and maintenance. Results: A significant mediational effect of social support on initial behavior change was indicated by the MacKinnon et al., bootstrap, and, marginally, Freedman–Schatzkin methods, but not by the Baron–Kenny method. No significant mediational effect of social support on maintenance of walking was found. Conclusions:  Methodologically rigorous intervention studies to identify mediators of change in physical activity are costly and labor ntensive, and may not be feasible with large samples. The use of statistically powerful tests of mediational effects in small-scale studies can inform the development of more effective interventions.

Internationalisation process for construction design service SMES on multi national projects

The internationalisation process has four key factors including market selection, decision to enter, entry modes and factors affecting entry modes. Small and medium sizes enterprises (SMEs) in the architectural engineering construction design services sector have demonstrated an increasing involvement in international markets. Consequently, activities and processes involved in internationalisation of these SME types present important issues for understanding from entrepreneurial, managerial and research perspectives. A research gap exists, however, through emphasis in past research having been given to large firms, and in particular those within manufacturing. This investigation identified similarities and differences between two construction design service SMEs who have been exporting to various localities including Eastern Europe, Africa, Middle East, UK, Asia and South America for typically more than two decades. Similarities and differences were identified within eight major constructs including: purpose, firm type, market image and design philosophy, entry mode strategy, institutional arrangement, factors affecting mode of entry, marketing selection and firm strategy in relation to project selection. The primary reasons for firms in both cases working in international markets were associated with the firms' motivations related to growth and enhancement of financial viability. Both firms were categorized as client following. This paper discusses the various internationalization processes and explains the reasons intrinsic to each case study. The two firms have been highly successful in the internationalization processes on multi-national projects die to a reflexive capability philosophy which incorporates continuous analysis and alignment between firm and locality characteristic to transform traditional barriers into enablers of success.

Small firm e-business adoption : a critical analysis of theory

Purpose – The paper critiques a range of theories and evaluates their ability to provide a lens for explaining the idiosyncratic nature of small firms and their e-business adoption decisions.

Design/methodology/approach – This literature review firstly summarises the existing research evidence that shows that small firms are idiosyncratic when it comes to e-business adoption. It then critiques theories commonly used in the literature in this field to examine the extent to which they take this small firm idiosyncrasy into account when explaining e-business adoption decisions.

Findings – The critical analysis shows that no commonly-used theory adequately explains small firm adoption of e-business because each omits important aspects of small firm idiosyncrasy. The analysis suggests that an integrated theoretical framework is needed. Preliminary ideas on this framework are provided.

Originality/value – Existing research generally applies a small number of selected theories and formulates research models of adoption factors. However, there is no systematic analysis of theories in this field and no consensus about theoretical frameworks. This paper addresses this limitation of the literature by critically evaluating the commonly used theories in terms of their individual suitability as lenses for explaining small firm e-business adoption.

Marketing strategy for small application service providers in a new market

Small to medium-sized enterprises (SMEs) including small application service providers (ASPs) are playing an increasingly important role in the development of global economies particularly in developing countries like China. This paper studies marketing strategies of small application service providers (ASP) with a focus on what the important factors are to establish a new ASP business in China. An analytical hierarchy process (AHP) method is used to analyse critical factors of the ASP industry. The research surveyed CEOs or senior managers who are working in ASP firms, to identify how a marketing strategy can be developed for an ASP firm to start business in China. It is found that the localisation of middle level managers, the localisation of products and services, the protection of intellectual property (IP), and infrastructure and transportation system are the most important factors for small ASP firms to do business in China.

Firm survival through a crisis : the influence of market orientation, marketing innovation and business strategy

As an outcome of the economic crisis, the global manufacturing sector is collapsing. Focusing on Chinese manufacturing small and medium enterprises (SMEs), this study investigates whether marketing innovation, defined as improvements in the marketing mix, can assist in withstanding the challenges of operating under the current economic conditions. A conceptual model linking market orientation, marketing innovation, competitive advantage and firm survival is tested using structural equation modelling. Three key findings are derived. First, the examined Chinese manufacturing SMEs had a greater perceived likelihood of survival had they developed and sustained a competitive advantage. Second, marketing innovation assisted in developing and sustaining competitive advantages based on differentiation and cost leadership strategies. Third, marketing innovation capabilities improved when the examined manufacturing SMEs were competitor oriented and had good inter-functional capabilities.

A comparison of the effectiveness of camera trapping and live trapping for sampling terrestrial small-mammal communities

Context. There is an increasing reliance on the use of camera-trap technologies for surveys of medium to large terrestrial mammals. Camera trapping may, however, also have significant applications for broad-scale surveys of small mammals.
Aims. The present study aims to compare results from camera-trapping surveys to those of the more traditional live trapping techniques. Specifically, it aims to test the effectiveness of the techniques for detecting species, and the cost effectiveness of both approaches.
Methods. Surveys were conducted across 36 sites in the Grampians National Park, Victoria, Australia, between April and July 2009. At each site, independent surveys were conducted for small mammals by using a combination of Elliot and cage trapping, then camera trapping. Results for the two different approaches were compared for both their ability to generate small-mammal presence data and their cost effectiveness.
Key results. Camera-trapping surveys of 36 sites in the Grampians National Park compared favourably with those of live trapping surveys. Similar species were detected across the sites, and camera trapping was a considerably more cost effective than live trapping.
Conclusions. Camera-trapping surveys of small terrestrial mammals may provide a new and cost-effective technique for surveying terrestrial small mammals. This is particularly the case when presence data are the main requirement of the survey, with no requirement to capture and tag animals.
Implications. Given the cost-effective nature of camera trapping, there is potential to use this approach to increase the level of replication and spatial coverage of small-mammal surveys. Improving the replication and spatial coverage of studies has the potential to significantly increase the scope of research questions that can be asked, thus providing the potential to improve wildlife management.

Pervasive limitations : innovating with ambient intelligence (AmI) technologies and restricted absorptive capacity in Australian SME manufacturers

The last 25 years have seen rapid increases in the number and sophistication of technological and process innovations in large manufacturers, producing dramatic improvements in productivity and efficiency. However, smaller manufacturers’ adoption of such innovations has been uneven. Ambient Intelligence (AmI) technologies are being positioned as the next performance and productivity enhancing purchase for manufacturers. This paper defines and gives examples of AmI technologies in current use, summarises AmI technologies of potential interest to small and medium enterprise (SME) manufacturers, and identifies potential impacts of restricted absorptive capacity in SMEs on the adoption of AmI technologies. Comparing two SME manufacturers, one from Germany and one from Australia illustrates a potential application of generic AmI technology based business solutions to a range of SME manufacturers.

A practical approach to achieving agility : a theory of constraints perspective

This article documents an action research (AR) project aimed at identifying the practical steps needed to become an agile manufacturer through a combination of the theory of constraints (TOC) and resource- based view (RBV) approaches in a small to medium enterprise (SME) in the Australian manufacturing sector. To date, lean production has been highlighted as a possible catalyst for creating an agile manufacturer, despite the evidence suggesting that lean manufacturing lacks the responsiveness and adaptability to effectively handle a rapidly changing market place and only works well in a stable environment. A more flexible system of production is required to fully encompass the agile characteristics needed to attain a competitive advantage. This research provides empirical evidence that the TOC perspective can be used as a practical approach for becoming an agile manufacturer. The study provides a workable approach for small firms to achieve ‘Agility’ in practice.

Inter-relationships between innovation and market orientation in SMEs

Purpose – This study aims to explore the nature of the interactions between two strategies, innovation and market orientation. By examining the components of these constructs the paper seeks to identify key components of market orientation that are antecedent factors of the innovation performance of the firm.

Design/methodology/approach – Correlation analysis was undertaken on data from a survey of 73 manufacturing firms in the Greater Western Sydney economic development zone in Australia. The data were supplemented by information obtained from the firm's annual reports.

Findings – Innovation was found to be positively correlated to market orientation (customer orientation, competitor orientation and inter-functional co-ordination) and both of these constructs were found to be positively correlated to firm performance and the degree of change in the firm's competitive environment.

Research limitations/implications – Possible limitations are: the low survey response rate; the nature of the sampled population; and the spread of industries involved, which could limit the generalisability of the results. The next steps will be to conduct deeper analysis into the factors that make up the subscales of the two constructs and to determine how market orientation or its associated activities interact with the innovation process.

Practical implications – In order to maximize a firm's financial performance, organizations should increase both their market orientation and their innovation activities as these factors operate synergistically.

Originality/value – This study is arguably the first to establish the finding that the degree of change in the competitive environment and the level of market orientation are linked, and the identification of the components of market orientation that are linked to firm innovation. These findings suggest that firm innovation and firm market orientation are strategic reactions to changes in the firm's competitive environment.

Supporting the online consumer decision process : electronic commerce in a small Australian retailer

The paper explores ways in which online retailers of physical products can utilise the Internet to support their consumers’ decision making processes. The approach followed by a small Australian retailer in selling boots online is examined. The case is analysed using theoretical constructs from consumer behaviour. It is concluded that it is indeed feasible even for small online retailers to successfully sell “look and feel” type goods such as footwear over the Internet. However, for this to occur, high levels of customer support is essential and online retailers need to engender consumer trust in terms of payment processing and product delivery.

Institutional environment, managerial attitudes and environmental sustainability orientation of small firms

This study examines the direct impact of three dimensions of the institutional environment on managerial attitudes toward the natural environment and the direct influence of the latter on the environmental sustainability orientation (ESO) of small firms. We contend that when the institutional environment is perceived by owner–managers as supportive of sound natural environment management practices, they are more likely to develop a positive attitude toward natural environment issues and concerns. Such owner–manager attitudes are likely to lead to a positive and proactive orientation of their firms toward environmental sustainability. The study uses survey data from 166 small manufacturing firms located in three Philippine cities. First, the study develops and tests the measurement models to examine the validity of the constructs representing the firm’s institutional environment, managerial attitudes toward the natural environment and the ESO of firms. Second, the study develops and tests the structural models examining the institutional environment–managerial attitudes–ESO linkages. Multi-sample invariance structural model analysis shows the mediating role of managerial attitudes in the institutional environment–ESO nexus. The findings show that ESO is a construct comprising three dimensions: knowledge of environmental issues, sustainable practices and commitment toward environmental sustainability. The cognitive, regulatory and normative elements of the institutional environment are strongly linked to positive managerial attitudes toward environmental sustainability, which in turn, positively influences the firm’s overall ESO. Managerial attitudes play a mediating role in the institutional environment–ESO linkages. The managerial, practical, research and policy implications of the research findings are discussed.

Do service and merchandise exporters behave and perform differently? : a New Zealand investigation

Research on export behaviour and the determinants of export performance of manufacturing firms abounds in the literature. By contrast relatively little research has been undertaken that focuses on service exporters despite the growing importance of service exports in most advanced industrialised countries. This paper compares the export behaviour and performance of service firms to those of manufacturing firms. The study is based on a survey of 155 small and medium size exporters from New Zealand. The results suggest that service exporters are distinctively unique in many respects and exhibit export behaviours that are different from exporters of merchandise. Generally, service firms have greater flexibility to adapt their products to the specific requirements of their customers, use direct export channels more often and are also more proactive than merchandise firms in the establishment of future export strategies. Overall, the size and commitment of service exporters have the greatest influence on their performance.

Approach for testing the material behavior in roll forming in a small scale

Roll forming of ultra-high strength steels (UHSS) and other high strength alloys is an advanced manufacturing methodology with the ability of cold forming those materials to complex three-dimensional shapes for lightweight structural applications. Due to their high strength, most of these materials have a reduced ductility which excludes conventional sheet forming methods under cold forming conditions. Roll forming is possible due to its low strains and incremental forming characteristic. Recent research investigates the development of high strength nano-structured aluminum sheet and titanium alloys, as well as their behaviour in roll forming with regard to formability, material behaviour and shape defects. The development of new materials is often limited to small scale samples due to the high preparation costs. In contrast, industrial application needs larger scale tests for validation, especially in roll forming where a minimum sheet length is required to feed the sample trough the roll forming machine. This work describes a novel technique for studying roll forming of a short length of experimental material. DP780 steel strips (500mm – 1300mm length) were welded between two mild steel carrier sheets of similar width and thickness giving an overall strip length of 2m. Roll forming trials were performed and longitudinal edge strain, bow and springback determined on the welded samples and samples formed of full length DP780 strip before and after cut off. The experimental results of this work show that this method gives a reasonable approach for predicting material behavior in roll forming transverse to the rolling direction. In contrast to that significant differences in longitudinal bow were observed between the welded sections and the sections formed of full length DP780 strip; this indicates that the applicability of this method is limited with regard to predicting longitudinal material behavior in roll forming.

Does workplace social capital buffer the effects of job stress? A cross-sectional, multilevel analysis of cigarette smoking among U.S. manufacturing workers

Objective: To investigate whether workplace social capital buffers the association between job stress and smoking status. Methods: As part of the Harvard Cancer Prevention Project's Healthy Directions—Small Business Study, interviewer-administered questionnaires were completed by 1740 workers and 288 managers in 26 manufacturing firms (84% and 85% response). Social capital was assessed by multiple items measured at the individual level among workers and contextual level among managers. Job stress was operationalized by the demand-control model. Multilevel logistic regression was used to estimate associations between job stressors and smoking and test for effect modification by social capital measures. Results: Workplace social capital (both summary measures) buffered associations between high job demands and smoking. One compositional item—worker trust in managers—buffered associations between job strain and smoking. Conclusion: Workplace social capital may modify the effects of psychosocial working conditions on health behaviors.
