I show within a two-period overlapping generations model with income tax evasion that when the penalty rate set by the government is su¢ ciently small, it is theoretically possible for the capital stock to exceed the golden-rule level on the balanced-growth path. However, such a dynamic inefficiency cannot be guaranteed when the probability of evasion detection is nil.

The majority of bird species studied to date have molt schedules that are not concurrent with other energy demanding life history stages, an outcome assumed to arise from energetic trade-offs. Empirical studies reveal that molt is one of the most energetically demanding and perplexingly inefficient growth processes measured. Furthermore, small birds, which have the highest mass-specific basal metabolic rates (BMRm), have the highest costs of molt per gram of feathers produced. However, many small passerines, including white-plumed honeyeaters (WPHE; Lichenostomus penicillatus), breed in response to resource availability at any time of year, and do so without interrupting their annual molt. We examined the energetic cost of molt in WPHE by quantifying weekly changes in minimum resting metabolic rate (RMRmin) during a natural-molt period in 7 wild-caught birds. We also measured the energetic cost of feather replacement in a second group of WPHEs that we forced to replace an additional 25% of their plumage at the start of their natural molt period. Energy expenditure during natural molt revealed an energy conversion efficiency of just 6.9% (±0.57) close to values reported for similar-sized birds from more predictable north-temperate environments. Maximum increases in RMRmin during the molt of WPHE, at 82% (±5.59) above individual pre-molt levels, were some of the highest yet reported. Yet RMRmin maxima during molt were not coincident with the peak period of feather replacement in naturally molting or plucked birds. Given the tight relationship between molt efficiency and mass-specific metabolic rate in all species studied to date, regardless of life-history pattern (Efficiency (%) = 35.720•10-0.494BMRm; r2 = 0.944; p =<0.0001), there appears to be concomitant physiological costs entrained in the molt period that is not directly due to feather replacement. Despite these high total expenditures, the protracted molt period of WPHE significantly reduces these added costs on a daily basis.

Low female participation rates in computing are a current concern of the education sector. To address this problem an intervention was developed — computing skills were introduced to girls in their English classes using three different teaching styles: peer tutoring, cross-age tutoring and teacher instruction (control). The sample comprised 136 girls from Years 8 and 10 from a single-sex government school. A pre-test post-test quantitative design was used. To describe the students perspectives, qualitative data were collected from six focus groups conducted with 8–10 students — one from each of the six classes. It was predicted that cross-age tutoring would yield more positive effects than peer tutoring which, in turn, would yield more positive effects than traditional teacher instruction as assessed by achievement on class tasks and attitudes towards computing. The hypothesis was not supported by the quantitative analysis, however in the qualitative data cross-age tutoring was appraised more favourably than peer tutoring or teacher instruction. The latter was the least preferred condition due to: (1) inefficiency; (2) difficulty understanding teachers' explanations; and (3) lack of teacher knowledge. Problems with the implementation of the intervention identified in the focus groups were teacher differences, system failures, missed classes, lack of communication, and selection of computing activities. Practical suggestions were provided relevant to the introduction of cross-age tutoring and the use of computers within secondary level English classes.

In recent years the provision of vocational education and training has been recognised as having a vital role to play in improving Australia's economic performance and in alleviating the hardship of the long term unemployed. The importance of education and training gives rise to the issue of operating educational institutions with a high level of efficiency. In this article, Data Envelopment Analysis is used to derive estimates of the technical and scale efficiency of Victorian Technical and Further Education Institutes in 1995. The results reveal substantial dispersion in technical and scale efficiencies. Regression analysis is used to identify variables which are associated with technical inefficiency.

This paper estimates technical efficiency of Australian textile and clothing firms based on the data obtained from the Business Longitudinal Survey (BLS) conducted by the Australian Bureau of Statistics (ABS). Using a Cobb Douglas stochastic production frontier the paper examines firm level technical efficiency in the time varying inefficiency effect model with technical inefficiency effects assumed as an independently distributed truncated normal variable. Estimates of the production frontier revealed significant but small elasticities of labour and capital for textile and clothing firms, respectively, and a negative (but insignificant) Hicks neutral technical change for both. Estimated coefficients of the explanatory variables for inefficiency effects indicated that technical efficiency varied significantly according to firms’ age, size, capital intensity, proportion of non-production to total workers and type of legal status. Predicted firm specific efficiency varied from 16 per cent to 95 per cent and mean efficiency ranged between 30 to 70 per cent. In view of these results policies have been suggested to improve technical efficiency of the firms as well as productivity growth of the sub sectors.

In the development of a web-based information system such as a demolition material management system, a great amount of diversified information on projects should be acquired from particular users located with various computer platforms. This issue is difficult to handle using the limited HTTP form submission, which could lead to inaccuracy of the information and inefficiency of the whole system. This paper describes a web-based graphical user interfaced, dynamic and distributed multimedia data acquisition mechanism, which accepts users' drawings and retrieval information from the canvas and stores the multimedia data on a server for further usages. Furthermore, techniques and principles needed to construct such a multimedia data acquisition tool are addressed in detail. The application of this distributed multimedia tool in developing a web-based demolition material management system is also described.

Against the background of increasing competition from globalization and the trend towards consolidation, diversification and rationalization, the study of efficiency is most relevant in the Malaysian Islamic banking context, where all domestic commercial banks operate Islamic banking schemes. Using the non-parametric method of Data Envelopment Analysis (DEA), this study investigates the recent efficiency of the Malaysian Islamic Banking system. The attributions of technical efficiency (utilization of capacity) and scale efficiency (optimality of scale achieved) are identified. Further, Islamic Banking Schemes operating under the dual banking system of foreign and domestic commercial banks were benchmarked to the country's two full-fledged Islamic banks to provide insight of the relative efficiencies. Amidst an overall improvement in TE and SE, it was noted that foreign banks (FB) increased efficiency levels to achieve full efficiency over the six-year period, and domestic banks (DB) followed by smaller improvement while the fully-fledged Islamic banks (FFIE) experienced a general decline in efficiency which was solely attributed to scale inefficiency. The findings provide useful guidelines for policy implications and may also assist banks concerned with their strategic planning with regard to the future of Islamic banking.

Habitat destruction and fragmentation, interactions with introduced species or the relocation of animals to form new populations for conservation purposes may result in a multiplication of population bottlenecks. Examples are the translocations of koalas to French Island and its derivative Kangaroo Island population, with both populations established as insurance policies against koala extinction. In terms of population size, these conservation programs were success stories. However, the genetic story could be different. We conducted a genetic investigation of French and Kangaroo Island koalas by using 15 microsatellite markers, 11 of which are described here for the first time. The results confirm very low genetic diversity. French Island koalas have 3.8 alleles per locus and Kangaroo Island koalas 2.4. The present study found a 19% incidence of testicular abnormality in kangaroo Island animals. Internal relatedness, an individual inbreeding coefficient, was not significantly different in koalas with testicular abnormalities from that in other males, suggesting the condition is not related to recent inbreeding. It could instead result from an unfortunate selection of founder individuals carrying alleles for testicular abnormalities, followed by a subsequent increase in these alleles’ frequencies through genetic drift and small population-related inefficiency of selection. Given the low diversity and possible high prevalence of deleterious alleles, the genetic viability of the population remains uncertain, despite its exponential growth so far. This stands as a warning to other introductions for conservation reasons.

This paper presents a method for conducting dynamic due diligence to evaluate Mergers and Acquisitions; demonstrates its effectiveness in a particular case; and extrapolates its theoretical and practical implications to the general case. It may be called the ‘ECIPP’ method - an acronym for: Establishing mandates; Creating projections; Identifying issues; Prioritizing procedures and Performing them.

Two established alternative due diligence methods are examined. The prevailing finance-theory-based procedure has the virtues of simplicity and elegance; the vice is abstraction. The prevailing practitioner-based regime has the virtues of thoroughness and concreteness but the vices of rigidity and inefficiency. Resolving the tradeoffs inherent in both static prescriptions provides an opportunity for a dynamic, innovative approach derived from grounded theory and an application of Hindle’s (1993) theory of venture renaissance through application of an enhanced paradigm of Entrepreneurial Business Planning. The ECIPP method retains simplicity, concreteness and thoroughness but eliminates abstraction, rigidity and inefficiency.

This is demonstrated in a case. ChildCo’s CEO had only one month to complete his M&A evaluation; no expertise or previous experience; severely limited budget for the exercise and had been flatly informed by prevailing M&A experts that what he wanted could not be done. Using the ECIPP method, the CEO and the author did it: on time, within budget and to the satisfaction of a previously skeptical board of one of the world’s largest multi-national companies including arguably the world’s most professional corporate M&A division.

The replicability logic of the case research permits two generalisations. (1) ECIPP extends the range and utility of Entrepreneurial Business Planning as a management technology, well beyond the constraints to which it is usually confined. (2) The ECIPP method of dynamic due diligence is an innovation worthy of mature consideration and further investigation by theorists and practitioners in the M&A field, in the disciplines of both Finance and Entrepreneurship and, well beyond, in the realms of general management theory, methodology and practice.

Although information communication technology (ICT) tool is long regard as very useful in today’s engineering, architectural and construction management, organizations cannot just only simply operate based upon its origin, but also requires the on-going observation, controlling measures, monitoring aids, adding features and fine-tuning actions to such tool before the desirable outcome can be achieved. However, it is a very common phenomenon that organizations purchase the licensed “off-the-shelf-software” ICT package and customize it to suit their own requirements. Due to the incapability and inefficiency of such software and customization, the possible result is making such tool becomes not user-friendly and obsolete.

The purpose of this paper therefore, as part of the doctoral research, is to review and report those actions taken by a construction organization to enhance the performance of its Enterprise Resource Planning (ERP) system upon launching it since December 2002. Such actions include: improving data inputting method; removing the transition bottleneck; introducing crystallization function; revising the organization’s “Delegation and Limits of Authority”; publishing the “League Table” amongst users; integrating the 3D Modeling into the system and adopting the “Resources Requirement Planning”.

Whilst the ultimate goals of this system are well beyond the time limit of the research project, an obvious interim result, achieved by this case studied organization, was winning a landmark project worth HK$5 billion after the ERP system was functioned effectively. The experience and success of this organization can be borrowed by those companies which are planning to adopt information technology (IT) strategy and use ICT tool in the architectural management system.

In October 2003, US citizen Christina Thomas died while scuba diving on Queensland’s Great Barrier Reef. Following over five years of delays, her husband David Watson accepted a plea bargain to which he pleaded guilty to manslaughter on the basis of criminal negligence. Watson was initially sentenced to four and a half years imprisonment, suspended after 12 months, however this was later increased on appeal to suspension after 18 months. Using Watson as a framework for analysis, this article examines some of the limitations of an inefficient justice system, with a particular focus on the private nature of the plea bargaining process, and the potentially favourable representations and sentencing of men who kill a female intimate partner. The authors argue that the need to respond to court inefficiency and under-resourcing in the criminal courts creates pressures that can result in a desire for increased efficiency being prioritised above other justice concerns, and this allows for existing flaws within the operation of the criminal justice system to be exacerbated, and excused.

We examine the performance of financial holding companies (FHCs) in Taiwan after the financial reform that removes the separation of banking, securities, insurance, and other financial services. Using data envelopment analysis, we find that FHCs fail to improve technical efficiencies in the post-reform era. They also do not outperform independent commercial banks after the financial reform. Lower technical efficiency caused by excess operating expenses appears to be the primary source of inefficiency. While scale efficiency may improve as FHCs grow larger, the benefits are marginal and insufficient to offset the potential costs of organizational diseconomies. Our findings suggest that increasing the size and scope of financial activities alone do not necessarily improve the performance of financial firms.

This paper investigates how unchecked manipulations could cause frequent trade-induced manipulations and weak-form market inefficiency in South Asian stock markets [Bombay Stock Exchange (BSE), Dhaka Stock Exchange (DSE) and Karachi Stock Exchange (KSE)]. Specifically, the paper analyses the price–volume relationship as one of the many cases of market inefficiency. By employing various econometric tests, this paper first provides conclusive evidence of market inefficiency in these markets. It then extracts evidence of manipulation periods from legal cases and analyses price–volume relationship during these periods. The paper finds that there exists market-wide trading-induced manipulations, where excessive buying and selling causes prices to inflate artificially before crashing down. The paper concludes that South-Asian markets are inefficient in the weak-form.

Project management plays an important role in successful completion of construction projects. One trend in the construction sector is a growing emphasis on project management. Ineffective integration of project management of project-based enterprises and operational processes of project owners, contractors and consultants prevents synergistic effects and causes resource waste and management inefficiency. Contemporary service theories, specifically service science and service-dominant logic, elucidate the involvement of clients in the creation of value and reinforce the nested relationship between project management service providers and clients. This study expands understanding of service theories by complementing service systems from project management and proposes a new framework for project management service systems, embedding service exchange and value co-creation in the construction processes. Research outcomes represent the importance of project management embedded with service theories in the construction industry and suggestions of research questions for future work.

For a developing economy with a given urban wage rate, globalization in capital markets strengthens labor unions. This result hinges on the fixed urban wage rate, which leads to a constant capital–labor ratio in the urban sector. Globalization via capital inflows not only enhances the employment effect of unionization but also reduces the rent-shifting related loss in production inefficiency to domestic capital, lending a support to labor unions for developing economies. This result is contrary to the common belief that labor unions tend to be weakened during the globalization process observed after 1980s in many developed economies.
