EDI Adoption in New Zealand Firms

Abstract Firms that have adopted Electronic Data Interchange (EDI) in their channel relationships are studied, with specific attention paid to the different roles that firms play in the EDI adoption process. Relationships are assessed by distinguishing between firms that adopted the technology in a proactive rather than a reactive role. The Political Economy Framework is used to provide a theoretical model to develop hypotheses about the factors that influence the adoption process for individual firms. A logistic regression model is employed to test the hypotheses. The results indicate that a number of organisational, environmental, as well as inter-organisational variables influence the different roles that firms play in the adoption process.
Inventory Routing Problem with Route Duration Limits and Stochastic Inventory Capacity Constraints

This paper studies the inventory management and routing problem in a two-level supply chain in which a single plant serves a set of warehouses, which in turn serve a set of customers with stochastic demands. A nonlinear integer program based on set partitioning and probabilistic chance constraint is proposed. The program accounts for the probabilities of inventory capacity violation, order quantity capacity, service levels, vehicle capacity restrictions, and route duration limits in the combined continuous inventory control and multidepot vehicle routing problem. Two tabu search heuristics differing in the way in which initial solutions were generated were applied to solve the problem. Computational tests on standard test networks revealed that the integration of the inventory management and routing decisions by solution of the combined inventory management and routing problem might yield cost savings of up to 14% over the cost of the sequential approach in which both problems were solved separately. The best objective function value obtained by the tabu search heuristic was found to increase with an increase in customer demand variance but decrease with an increase in order quantity capacity and route duration limit. Variance of the customer demand was found to have a significant impact on the quality of the solution.
Denitrification Rates in a Marine Sediment as Measured by the Acetylene Inhibition Technique

A method has been developed for measurement of denitrification activity in sediments by application of the acetylene inhibition technique. Acetylene-saturated water was injected, at close intervals, into sediment cores which were then incubated for a few hours at the in situ temperature. Frozen segments of the cores were assayed for accumulation of N2O by a combined gas extraction and detection system. The segments were thawed under a stream of helium from which N2O (and other gases) was collected in a liquid N2 trap, and the quantity of N2O was measured by gas chromatography. The maximum rate of denitrification in a coastal marine sediment was 35 nmol of N per cm3 of sediment per day at 2.5°C, and the rate of denitrification for the total sediment was 0.99 nmol of N per m2 per day.
Human T-Cell Leukemia/Lymphoma Virus Type 1 p30, but Not p12/p8, Counteracts Toll-Like Receptor 3 (TLR3) and TLR4 Signaling in Human Monocytes and Dendritic Cells

ABSTRACT The human T-cell leukemia/lymphoma virus type 1 (HTLV-1) p30 protein, essential for virus infectivity in vivo, is required for efficient infection of human dendritic cells (DCs) but not B and T cells in vitro. We used a human monocytic cell line, THP-1, and dendritic cells to study the mechanism of p30 and p12/p8 requirements in these cell types. p30 inhibited the expression of interferon (IFN)-responsive genes (ISG) following stimulation by lipopolysaccharide (LPS) of Toll-like receptor 4 (TLR4) and by poly(I·C) of TLR3 but not of TLR7/8 with imiquimod. Results with THP-1 mirrored those for ex vivo human primary monocytes and monocyte-derived dendritic cells (Mo-mDC). The effect of p30 on TLR signaling was also demonstrated by ablating its expression within a molecular clone of HTLV-1. HTLV-1 infection of monocytes inhibited TLR3- and TLR4-induced ISG expression by 50 to 90% depending on the genes, whereas the isogenic clone p30 knockout virus was less effective at inhibiting TLR3 and TRL4 signaling and displayed lower infectivity. Viral expression and inhibition of ISG transcription was, however, rescued by restoration of p30 expression. A chromatin immunoprecipitation assay demonstrated that p30 inhibits initiation and elongation of PU.1-dependent transcription of IFN-α1, IFN-β, and TLR4 genes upon TLR stimulation. In contrast, experiments conducted with p12/p8 did not demonstrate an effect on ISG expression. These results provide a mechanistic explanation of the requirement of p30 for HTLV-1 infectivity in vivo, suggest that dampening interferon responses in monocytes and DCs is specific for p30, and represent an essential early step for permissive HTLV-1 infection and persistence.
Private Equity Performance Under Extreme Regulation

This study investigates the impact of excessive regulation on private equity (PE) returns and firm performance. History shows that extreme regulation and prohibition reduce the supply of capital and raise returns (e.g., as with drugs and diamonds). However, for value-added investors such as PE funds, extreme regulation also reduces the quality of capital and fund involvement. The net effect on returns is therefore ambiguous and heretofore not studied. With a new unique dataset, this paper empirically examines the performance of PE investments in Italy when leveraged buyouts are strictly regulated. The data show that extreme regulation reduces not only the supply of capital, but also PE returns and firm performance, as well as the likelihood of an IPO exit.
Land redistribution in KwaZulu‐Natal: An analysis of farmland transactions in 1997

This article presents the results of a census survey of all farmland transactions in the province of KwaZulu-Natal during the calendar year 1997. Data recorded by the Deeds Registry were stratified and analysed by race, gender and mode of land acquisition. It was estimated that 372 995 hectares, or 7 per cent, of the area available for redistribution have been transferred to new owners. Of this, just 0,43 per cent of the available area was redistributed to disadvantaged people. Although low, the rate of redistribution appears to have increased dramatically since 1995. The quality of land varied markedly across different modes of land redistribution. Land purchased with government grants was of a much lower agricultural quality than land purchased privately. Relative to government-assisted transactions, private market transactions accounted for a slightly smaller share of the area transferred to disadvantaged people but for a much larger share of the value of land redistributed. Inheritance and land donations accounted for the remaining redistributed land. Women were well represented in land transactions involving inheritance but were underrepresented in transactions financed with mortgage loans. In general, they acquired farms of much smaller size and land of lower quality than men.
Differential Response of the Epithelium and Interstitium in Developing Human Fetal Lung Explants to Hyperoxia

Hyperoxia is closely linked with the development of chronic lung disease of prematurity (CLD), but the exact mechanisms whereby hyperoxia alters the lung architecture in the developing lung remain largely unknown. We developed a fetal human lung organ culture model to investigate (a) the morphologic changes induced by hyperoxia and (b) whether hyperoxia resulted in differential cellular responses in the epithelium and interstitium. The effects of hyperoxia on lung morphometry were analyzed using computer-assisted image analysis. The lung architecture remained largely unchanged in normoxia lasting as long as 4 d. In contrast, hyperoxic culture of pseudoglandular fetal lungs resulted in significant dilatation of airways, thinning of the epithelium, and regression of the interstitium including the pulmonary vasculature. Although there were no significant differences in Ki67 between normoxic and hyperoxic lungs, activated caspase-3 was significantly increased in interstitial cells, but not epithelial cells, under hyperoxic conditions. These changes show that exposure of pseudoglandular lungs to hyperoxia modulates the lung architecture to resemble saccular lungs.
A Critical Analysis of Auditors' Perception of the Impact of Section 404 of the Sarbanes Oxley Act on Audit Quality: An Egyptian Perspective

The recent accounting scandals that have occurred in the USA have resulted in the issuance of the Sarbanes Oxley Act (SOX), with emphasis on Section 404 related to enhancing the companies' internal controls. This research study critically examines Section 404 requirements, surveying a sample of Egyptian auditors in a number of audit firms with international affiliations about their perception of the expected costs and benefits that could result from applying Section 404, and whether such requirements could have a positive impact on the quality of audit. The results provide evidence based on auditors' opinions that the benefits associated with Section 404 applications are expected to outweigh its costs, with possible reduction of Section 404 costs in the future period. Moreover, the results indicate that both the additional audit procedures required in the audit of internal control over financial reporting (ICOFR) and the increased legal liability that will be imposed on auditors through compliance with Section 404 requirements are expected to improve the quality of the audit process. The results of the study call for the application of similar requirements of Section 404 taking into consideration the characteristics and other elements affecting the Egyptian businesses, accounting and auditing profession.
Organizational Trust, Trust in the Chief Executive and Work Satisfaction

This article examines the interrelationships among employee trust in the chief executive of the organization, trust in the organization and work satisfaction. These three concepts capture the essential experience of the employee's work life, but their interrelationships have been more often a subject for speculation than for research. Employees in one government organization and one manufacturing firm offered their visions of critical features in managerial trust and organizational trust. With respect to defining chief executive trust, employees emphasized the manager's employee orientation, honesty, ability, fairness and forthrightness. Critical features that employees used to define organizational trust included the social significance of organizational mission, quality of output, and the organization's persistence beyond the human lifespan. Trust in the chief executive and organizational trust were found to be uncorrelated with one another, as expected from the conceptual review. Instead, these variables were conceptually linked through their individual relationships with employee work satisfaction.
The path to graduation: a model interactive web site design supporting doctoral students

Objective. This 2-phase mixed method study assessed 2-year doctoral students’ and dissertation students’ perceptions of the current Graduate School of Education dissertation support Web site, with implications for designing a model dissertation support Web site. Methods. Phase 1 collected quantitative and qualitative data through an anonymous electronic survey. Phase 2 consisted of 6 semistructured qualitative Skype interviews. Four themes emerged from the qualitative portion of the study: (a) Mentoring, (b) Student Support Groups, (c) Explicit functions and roles of Dissertation Chairpersons, and (d) the Opportunity to network and interact with dissertation students face-to-face or online. Results. Of the respondents, 42.3% found the web content such as forms and resources helpful and 40% indicated the visual appearance was helpful. Overall, 8.3% were very satisfied, 16.7% were satisfied, 33% neutral, 33.3. % were dissatisfied, and 8.3% very dissatisfied with the current Web site. Among them, 78.3% would like to see e-mentoring implemented on the Web site and 83.3% would participate in a Dissertation Retreat/Bootcamp. Conclusions. The findings concluded e-mentoring and webinars, as the 2 most desired Web 2.0 technology to enhance the current Web site. The data suggested the most desired type of formal or informal event to add to a model Web site is a Dissertation Retreat/Bootcamp. Recommendations. Decision makers at the departmental and institutional level should strongly consider incorporating e-mentoring/peer mentoring, increased availability of dissertation chairpersons to walk students through the various stages of the dissertation process, a model of the entire process from start to finish, and the use of Web 2.0 tools to foster support and keep students connected, on the
Employment and the “Investment Gap”: An Econometric Model of European Imbalances

We specify a VEC model based on six main macroeconomic imbalances to explain the Great European Recession, in Germany, France, Spain and Italy, from 1999 to 2013, estimating their long-term relationships. We focus on employment and unemployment as the main imbalances and identify consumption and investment slumps, prompted by fiscal consolidation, as the causes and current account rebalance and low inflation as the main consequences. Our main results are the following: a) public investment is the main policy instrument which can foster employment, prompting private investment and growth, exports can only partly balance a falling domestic demand; b) the unemployment-current account trade-off is a structural constraint to a lower unemployment level; c) mild deflation set in as a consequence of the consumption slump and oil price decline; d) breaks dates for consumption and inflation thresholds are estimated; and e) Germany successfully passed through the European recession by sharply increasing its exports and reshaping its economic role.
Occupational asthma in Singapore.

AIM Since the first notified case of occupational asthma in 1983, a total of 90 cases were confirmed as on 31st December 1999. In this study, demographic data, causative agents and impact on the workers were described. METHODS The data was derived from notifications to the Ministry of Manpower and referrals to the Occupational Lung Disease Clinic jointly run with Department of Respiratory Medicine, Tan Tock Seng Hospital. RESULTS Of the 90 cases, 19 (21%) were females and 71 (79%) were males. There were 48 (53%) Chinese, 22 (24%) Malays, 14 (16%) Indians and 6 (7%) of other ethnic origins. The mean age at diagnosis was 35.8 +/- 9.3 yrs. The mean duration of exposure prior to onset of symptoms was 34.9 +/- 57.3 months. The most common causative agent was isocyanates (28 cases, 31%) followed by solder flux (12 cases, 13%) and welding fumes (8 cases, 9%) respectively. Thirteen (14.4%) workers were assessed to have permanent disability under the Workmen's Compensation Act. CONCLUSIONS Since 1990, occupational asthma has overtaken silicosis and asbestosis as the most common occupational lung disease in Singapore. The most common causative agent is isocyanates. Occupational asthma is a condition associated with disability in the workplace and may still be largely under-reported.
Clinical feasibility of brain-computer interface based on steady-state visual evoked potential in patients with locked-in syndrome: Case studies.

Although the feasibility of brain-computer interface (BCI) systems based on steady-state visual evoked potential (SSVEP) has been extensively investigated, only a few studies have evaluated its clinical feasibility in patients with locked-in syndrome (LIS), who are the main targets of BCI technology. The main objective of this case report was to share our experiences of SSVEP-based BCI experiments involving five patients with LIS, thereby providing researchers with useful information that can potentially help them to design BCI experiments for patients with LIS. In our experiments, a four-class online SSVEP-based BCI system was implemented and applied to four of five patients repeatedly on multiple days to investigate its test-retest reliability. In the last experiments with two of the four patients, the practical usability of our BCI system was tested using a questionnaire survey. All five patients showed clear and distinct SSVEP responses at all four fundamental stimulation frequencies (6, 6.66, 7.5, 10 Hz), and responses at harmonic frequencies were also observed in three patients. Mean classification accuracy was 76.99% (chance level = 25%). The test-retest reliability experiments demonstrated stable performance of our BCI system over different days even when the initial experimental settings (e.g., electrode configuration, fixation time, visual angle) used in the first experiment were used without significant modifications. Our results suggest that SSVEP-based BCI paradigms might be successfully used to implement clinically feasible BCI systems for severely paralyzed patients.
The Role of Labour Market Expectations and Admission Probabilities in Students' Application Decisions on Higher Education: The Case of Hungary

Abstract This paper analyses students’ application strategies to higher education, the effects of labour market expectations and admission probabilities. The starting hypothesis of this study is that students consider the expected utility of their choices, a function of expected net lifetime earnings and the probability of admission. Based on a survey carried out among Hungarian secondary school students, three aspects of application decisions are investigated: the number of applications; the selection between state‐funded and cost‐priced education; and the institutions/field specialization ranked first and last in students’ choices. The results of this paper confirm that both expected wages and admission probabilities determine students’ application strategies and that the seemingly irrational student preferences for institutions/orientations with less favourable labour market opportunities might be the result of a rational decision process.
The Effects of Securitization on Consumer Mortgage Costs

We examine the effects of securitization on two dimensions of consumer mortgage costs: coupon rates and loan origination fees. We find no evidence that securitization reduces the coupon rates on fixed- or adjustable-rate mortgages. Instead, securitization appears to lower mortgage loan origination fees, resulting in substantial savings for consumers. Securitization activity includes passthrough creation and collateralized mortgage obligation (CMO) creation. We test for differences between the effects of passthrough and CMO creation on primary mortgage costs. Surprisingly, these activities appear to have indistinguishable effects on loan rates and origination fees, suggesting that a large derivatives market for mortgage loans is not creating value for consumers.

Breed effects and retained heterosis for growth, carcass, and meat traits in advanced generations of composite populations of beef cattle.

Retained heterosis for growth, carcass, and meat traits was estimated in F3 generation castrate male progeny in three composite populations finished on two levels of dietary energy density (2.82 Mcal of ME and 3.07 Mcal of ME and 11.50% CP) and serially slaughtered at four end points at intervals of 20 to 22 d. Breed effects were evaluated in nine parental breeds (Red Poll [R], Hereford [H], Angus [A], Limousin [L], Braunvieh [B], Pinzgauer [P], Gelbvieh [G], Simmental [S], and Charolais [C] that contributed to the three composite populations (MARC I = 1/4 B, 1/4 C, 1/4 L, 1/8 H, 1/8 A; MARC II = 1/4 G, 1/4 S, 1/4 H, 1/4 A; and MARC III = 1/4 R, 1/4 P, 1/4 H, and 1/4 A). Breed effects were important (P < .01) for carcass weight, dressing percentage, fat thickness, and marbling score; for retail product, fat trim and bone percentages and weights at two levels of fat trim (8 and 0 mm); and for carcass lean, fat, and bone percentages and weights. Mean slaughter weight was 54.7 kg greater for the Simmental, Gelbvieh, and Charolais breeds than for the Limousin but did not differ (P > .05) from Limousin in retail product weight or carcass lean weight because of higher dressing percentage, lower fat trim percentage, and lower bone percentage of Limousin. The effects of dietary energy density were important (P < .01) for most traits. The interaction of breed group x dietary energy density generally was not important. Retained heterosis generally was significant for each composite population for weight of retail product, fat trim, bone, and carcass lean, fat, and bone. For percentage of retail product, fat trim, carcass lean, carcass fat, and chemical fat in the 9-10-11th rib cut, generally, heterosis was significant for composites MARC II and MARC III but not for composite MARC I (i.e., composites MARC II and MARC III had a lower percentage of retail product and carcass lean and a higher percentage of fat trim, carcass fat, and chemical fat in the 9-10-11th rib cut than the mean of contributing purebreds).
Strategic Integration and Devolvement of Human Resource Management in the UK Manufacturing Sector

This paper analyses the practices of ‘integration’ of HRM into the corporate strategy and ‘devolvement’ of responsibility for HRM to line managers in six British manufacturing industries. The findings are based on a questionnaire survey, in-depth interviews and cognitive mapping methodologies. The results show that over 50% of the firms under study practise a high level of strategic integration. On the other hand, over 61% of the sample firms practise a low level of devolvement practices. Interestingly, both the practices of integration of HRM into the corporate strategy and devolvement of HRM to line managers are more determined by a number of organizational policies than traditional contingent variables. The adoption of the mixed methodology has been useful. The findings contribute to strategic HRM literature, and also have some key messages for policy-makers in the field. The cognitive maps developed in the paper could be used to give feedback and training to managers.
Analysis and performance evaluation of an efficient handover algorithm for cognitive HetNets

Cognitive heterogeneous network is a promising technology to meet the requirements of future wireless networks in cost and energy efficiency. By using vertical handover (VHO) between different network tiers, such as macro and femto, the traffic congestion can be potentially alleviated, and the spectral efficiency is significantly increased. However, performing VHO for a cognitive handover user (CHU) and simultaneously guaranteeing the quality of service of the primary user (PU) is the most challenging issue in such a network. This paper proposes an efficient VHO strategy in a cognitive heterogeneous network, which considers both adaptive average received signal and spectrum availability, namely, average received signal and spectrum availability. To analyse the performance of the proposed average received signal and spectrum availability algorithm, several metrics are investigated. First, the assignment probability of a CHU from a macro base station to a femto base station is evaluated and simplified in a closed‐form expression. Then, the outage probability of a CHU and collision probability of the PU are theoretically investigated for the proposed algorithm and are compared with 2 well‐known algorithms, the modified received signal strength–α and the received signal strength and wireless transmission loss. We also introduce a new performance metric, referred to as figure of merit, which jointly considers the assignment and outage probability of a CHU, collision probability of a PU, and the number of unnecessary handovers of a CHU. Figure of merit effectively shows the superiority of the proposed handover algorithm to conventional ones.
