THE ROLE OF POSTOPERATIVE PATIENT POSTURE IN THE RECURRENCE OF TRAUMATIC CHRONIC SUBDURAL HEMATOMA AFTER BURR‐HOLE SURGERY

OBJECTIVEChronic subdural hematoma (CSDH) is one of the most common types of intracranial hemorrhage, especially in the elderly, with a significant recurrence rate ranging from 9.2 to 26.5%. The role of postoperative patient posture in the recurrence of CSDH has not been studied sufficiently. METHODSA total of 84 consecutive patients with unilateral traumatic CSDH without known risk factors of CSDH recurrence were prospectively enrolled in this study. All patients underwent burr-hole surgery with closed system drainage and were then allocated randomly to either of two groups: Group A (n = 42) patients were kept in a supine position for 3 days after the operation, whereas Group B (n = 42) patients assumed a sitting position in bed, with the head of the bed elevated to 30 to 40 degrees, for the same duration as Group A. After 3 days, there was no restriction in patients' activities in both groups. All patients were followed-up for at least 3 months after surgery. RESULTSThe groups were not significantly different in age, sex, presence of brain atrophy or hydrocephalus, preoperative hematoma width, and postsurgery subdural space width. The recurrence rate in Groups A and B were 2.3 and 19.0% (necessitating repeat surgery in one patient), respectively (P = 0.02). Other complications in Groups A and B, respectively, were atelectasis (10 versus seven; P = 0.41), pneumonia (five versus four; P = 0.72), decubitus ulcer (three versus two; P = 0.64), and deep vein thrombosis (zero versus one; P = 0.31). CONCLUSIONAssuming an upright posture soon after burr-hole surgery was associated with a significantly increased incidence of CSDH recurrence but not with a significant change in other position-related postsurgical complications. According to this result, it is not recommended that elderly patients assume an upright posture soon after burr-hole surgery to prevent postoperative atelectasis and dementia, as these might significantly increase the risk of CSDH recurrence.
Trade influences in Australia's allocation market: can allocations provide environmental water?

Over the last 25 years water markets in Australia have been used to transfer water entitlements and allocations between irrigators, helping them to manage the risks associated with water supply and the demand for structural change. More recently governments have entered entitlement markets to purchase water for the environment. This paper hypothesises that a focus on purchasing entitlements will not motivate a sufficient number of irrigators to engage in the provision of environmental water. It is hypothesised that governments may need to enter the allocation market to secure long-term arrangements for counter-cyclical provision of environmental water. Avoiding any negative impacts of interference on the traditional users of this market requires a greater understanding of how irrigators currently use allocations, and what drives their decisions to buy and sell. This paper provides the findings of qualitative research involving 39 irrigators in three states within the Murray-Darling Basin in Australia. The findings provide a preliminary assessment of the factors influencing irrigators’ decisions to trade allocations and how these factors change across and within seasons. Irrigator attitudes toward government use of the allocation market to support counter-cyclic environmental water provision are also examined. Overall, irrigators appear comfortable with the notion of trading in allocations with the government, rather than in entitlements alone.
Investigating temporal effects of risk perceptions and satisfaction on customer loyalty

Purpose – The purpose of this paper is to examine how product usage satisfaction mediates the link between two types of perceived risk and loyalty intentions, and investigate the three moderating effects (overall satisfaction of provider, switching costs, and remaining contract time) of the product usage satisfaction-loyalty intentions linkage. Design/methodology/approach – Using a longitudinal study, a total of 253 usable responses are collected from time T to time T+1. The paper uses the partial least squares (PLS-Graph 3.0) approach for structural parameters in the proposed model. Findings – The findings show that the temporal effect of performance risk and product usage satisfaction negatively increases, whereas the temporal effect between product usage satisfaction and loyalty intentions decreases over time. While the moderating effect between overall satisfaction of provider and product usage satisfaction strengthens loyalty intentions, the switching costs attenuate loyalty intentions. The proposed .
The dynamic resource-based view: capability lifecycles

This article introduces the concept of the capability lifecycle (CLC), which articulates general patterns and paths in the evolution of organizational capabilities over time. The capability lifecycle provides a structure for a more comprehensive approach to dynamic resource-based theory. The analysis incorporates the founding, development, and maturity of capabilities in a manner that helps to explain the sources of heterogeneity in organizational capabilities. In addition, the analysis includes the "branching" of an original capability into several possible altered forms.
A phase II study of autologous irradiated tumor cells plus BCG in patients with metastatic malignant melanoma

Eighteen patients with surgically incurable metastatic malignant melanoma were treated with a mixture of irradiated (15,000 rads) autologous tumor cells (1‐2 × 108) and BCG (Glaxo, 2‐4.5 × 106 organisms), which was injected intradermally (in five divided doses) every 2 weeks (X5). Four of 18 (22%) evaluable patients achieved objective remissions. It is concluded that this treatment regimen does not have general clinical application because the remissions were infrequent, of short duration (median, 3 months) and occurred only in patients with minimal, nonvisceral tumor burdens.
The association between accounting standards, legal framework and the quality of financial reporting by a government ministry in Uganda

Purpose – The purpose of this study is to examine the association between accounting standards, legal framework and the quality of financial reporting by the Ministry of Water and Environment in Uganda.Design/methodology/approach – The study used a self‐administered questionnaire to survey 120 staff and stakeholders of the Ministry of the Water and Environment. Correlation analysis was employed to determine the association between accounting standards, legal framework and the quality of financial reporting.Findings – Results indicate that accounting standards and legal framework are all positively and significantly associated with the quality of financial reporting, providing evidence of the effect of accounting standards and legal framework on the quality of financial reporting in UgandaResearch limitations/implications – Scarce literature using African data means that it is not possible to compare the findings to previous research.Practical implications – The finding of an association between accounting.
The Dynamics of a Tippe Top

Despite the numerous studies devoted to the dynamics of a spinning top, some disputable issues concerning the classical motion still remain unsettled. The complexity of the six degree-of-freedom motion is compounded by the assumptions that must be made about the friction law. In this paper, a numerical model based on a more general description of contact friction is developed to simulate the unusual flip behavior of an old toy, known as the Tippe top. The results appear to explain some of the puzzles raised and disputed by previous investigators.
Differences in IGF axis‐related proteins in amniotic fluid of trisomy 21 and trisomy 18 using a multiple reaction monitoring approach

Trisomy 21 and trisomy 18 are the two most common chromosomal anomalies in live births. To find new biomarkers for aneuploidies and pathogenesis of fetal malformations, we measured insulin‐like growth factor (IGF) axis‐related proteins in amniotic fluid (AF) of pregnant women carrying trisomies 21 or 18 affected fetuses using multiple reaction monitoring (MRM) approach.
Performance evaluation for Geographical and Energy Aware Routing protocol

Geographic and Energy Aware Routing (GEAR) protocol uses energy aware neighbor selection to route a packet towards the target region and geographic forwarding or flooding approaches to disseminate the packet inside the destination region. The objective of this protocol is to fairly balance the energy among neighbor nodes. However, being distance aware by the geographic routing or energy aware creates conflicting goals such as obtaining minimal delay, increasing energy balancing and increasing system delivery ratio. Towards this end, this paper evaluates the performance of GEAR protocol and investigates the possibility to optimize its operation to achieve greatest performance. A prototype of a simulator is implemented using Java. A performance evaluation is performed and demonstrated on several scenarios using different values of preference weight for distance and energy balancing in each node's routing decision. This includes static centralized strategy, dynamic and adaptive de-centralized strategies. Results show that best performance is achievable at different operation points in all strategies.

Moreover there is a tentative lean supply chain model contribution.Design/methodology/approach – To test lean approaches in the Catalan pork supply chain we have used case research methodology. The research strategy started with a conceptual model proposal as a tool to carry out the assessment. The research went on a multiple case studies in a large‐scale sample of the population and developed a semi‐structured interview as a basic instrument to apply it.Findings – The article shows the pork sector has actively adopted the productive techniques associated with lean management. The structure of the specific chain in the Catalan pork sector is suitable to implement lean supply chain strategies according to the presented model.Research limitations/implications – This paper should be of value .
Elevated serotonin transporter binding in depressed patients with Parkinson's disease: A preliminary PET study with [11C]DASB

This study investigated whether abnormalities in serotonin transporter binding occur in Parkinson's disease (PD) patients with concurrent depression. We estimated serotonin transporter levels in seven clinically depressed early‐stage PD patients and in seven healthy matched‐control subjects during a single positron emission tomography (PET) scan with the serotonin transporter radioligand, [11C]DASB. Depressed PD patients displayed a wide‐spread increase (8–68%) in [11C]DASB specific binding outside of the striatum, which was significant in dorsolateral (37%) and prefrontal (68%) cortices. Elevated [11C]DASB binding was positively correlated with depressive symptoms but not with disease severity or duration. Compatible with recent PET/[11C]DASB findings in major depression, the present preliminary data suggest that increased [11C]DASB binding, possibly reflecting greater serotonin transporter density (up‐regulation), might be a pathological feature of depression in Parkinson's disease—and possibly a characteristic of depressive illness in general. © 2008 Movement Disorder Society
Optimal Nonlinear Redistributive Taxation and Public Good Provision in an Economy with Veblen Effects

This paper deals with the consequences of the assumption of negatively interdependent preferences for the shape of the optimal nonlinear income tax and the effcient level of public good provision in a setting where the policy maker maximizes an inequality averse social welfare function and the agents’ market ability is private information. The analysis points out that the terms added in the tax formulas due to the presence of Veblen effects might justify a reduction in the optimal marginal tax rates faced by the different individuals. Also, the desirability of negative marginal tax rates cannot be ruled out. With respect to the issue of the optimal level of public good provision, we derive a modfied Samuelson rule and highlight the fact that the Veblen-based part of the formula might require to distort downwards the efficient level of public good provision.
Assessing the Impact of Country of Origin on Product Evaluations: A New Methodological Perspective

A new methodological approach for examining the impact of country of origin on product evaluations is proposed. It takes the form of a multiattribute attitudinal model analyzed by means of a system of simultaneous equations. This approach makes possible examination of the impact of other attributes as well as country of origin on evaluations, and takes into consideration the effect of familiarity and knowledge about the product class. Differences between respondents of two different national origins are also investigated because previous research indicates differences in country stereotyping by nationality.
Human Resource Development Mechanism and the Performance of Public Sector Accountants' in Nigeria

The study examines human resource development on the performance of public sector accountants' in Nigeria. The quality of accountants' available is a function of reliable and acceptable financial reporting framework that will improve productivity in the public sector. This can only be achieved through an effective and efficient human resource development structure. To achieve the objective of the study, primary and secondary data were used. The primary data was obtained through a well structured questionnaire administered to one hundred and nineteen public sector accountants in Bayelsa State and the data obtained were analysed with econometric models of multiple regression, granger causality test and diagnostic test. The Cronbach's alphas model was used to verify the reliability of the instrument. The study found that job training, performance appraisal, career planning and reward employee welfare was positively related to productivity of public sector accountants' in Nigeria. Based on these findings, the implications for human resource development mechanism practice and recommendations were discussed.
A benchmarking framework for information systems management issues in Kuwait

Purpose – Aims to demonstrate the importance of reporting IS management constructs rather than reporting and ranking the individual management issues; determine whether the ratings of IS management factors differ across organizational and personal variables; and benchmark the position of Kuwait's results on dimensionality and determinants of IS management issues with that of other previous studies.Design/methodology/approach – This field study considered only the opinions of the highest ranked executives of the IS functions within their organizations. A seven‐page structured interview guide was used for data collection. Principal component factor analysis was performed on the issue ratings in order to determine underlying IS management factors. Confirmatory factor analysis was performed to further assess how well the factors fit the issue data and to test the fit of the resulting factor model. Finally, t‐tests were performed to test whether the differences between factors were significant in order to demo.
Migraine: A Comprehensive Review of New Treatment Options

Headaches are among the most common complaints reported to health care professionals and are classified by the International Headache Society as migraine, tension‐type, or cluster, with additional subtypes. Classification and etiology of headache should be determined after thorough review of the patient's history. Once diagnosed, migraine can be treated by preventive or abortive measures. Recent developments add new options, including availability of drugs for intranasal administration (sumatriptan, dihydroergotamine) and 5‐HT1B/1D agonists (rizatriptan, zolmitriptan, naratriptan, eletriptan). Although placebo‐controlled trials are available, few comparative clinical trials of these agents have been conducted; however, important pharmacologic, pharmacokinetic, and clinical differences exist among the drugs.
Employee Resourcing and Performance of Small and Medium Enterprises in Lagos State, Nigeria

The objective of this study is to investigate if employee resourcing can be used to predict the performance of Small & Medium Enterprises (SMEs) in Lagos State, Nigeria. The study adopted the survey research design. Sources of data for the study were primary, secondary, and tertiary. The instruments for the study were in-depth interview and self developed questionnaire using a 4-point Likert scale. A sample of owners/managers of SMEs was drawn from the target population using stratified random sampling techniques. Of the 450 copies of questionnaire administered, 257 copies were returned representing 57 per cent response rate. The reliability test (Cronbach’s Alpha) of the instrument yielded 0.60. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 16. The major finding of the study is that although there is a mild association (0.113) between employee resourcing and performance, it is not strong enough to predict the performance of the sampled SMEs. Most of the owners/managers interviewed opined that retaining employees was one of their greatest challenges but not strong enough to determine the level of their performance as they have always envisaged that some of their staff can leave the organization. Hence, adequate provision is made for skilled manpower shortage. Therefore it is recommended that recruitment and selection should be outsourced to firms which specialize in recruiting employees. This will enable the owners/managers to focus more on the core activities of their SMEs.
A strong comparison principle for positive solutions of degenerate elliptic equations

A strong comparison principle (SCP, for brevity) is obtained for nonnegative weak solutions u ∈ W 1,p 0 (Ω) of the following class of quasilinear elliptic boundary value problems, (P ) −div(a(x,∇u))− b(x, u) = f(x) in Ω; u = 0 on ∂Ω. Here, p ∈ (1,∞) is a given number, Ω is a bounded domain in IR with a connected C-boundary, a(x,∇u) and b(x, u) are slightly more general than the functions a0(x)|∇u|∇u and b0(x)|u|u, respectively, with a0 ≥ const > 0 and b0 ≥ 0 in L∞(Ω), and 0 ≤ f ∈ L∞(Ω). Validity of the SCP is investigated also in the case when b0 ≤ 0 depending upon whether p ≤ 2 or p > 2. The methods of proofs are new.

EFFECT OF INVENTORY MANAGEMENT PRACTICES ON ORGANIZATIONAL PERFORMANCE IN PUBLIC HEALTH INSTITUTIONS IN KENYA: A CASE STUDY OF KENYATTA NATIONAL HOSPITAL

The purpose of this study was to investigate the effect of inventory management practices on organizational performance in public health institutions in Kenya. The specific objectives were to establish: the effect of inventory shrinkage, inventory investment, inventory turnover, and inventory records accuracy on organizational performance of Kenyatta National hospital: A descriptive case study design was used. Statistical analysis was carried out using SPSS. The study revealed that inventory investment and inventory records accuracy have a positive influence on organizational performance while inventory shrinkage have a negative effect on organizational performance of Kenyatta National hospital thus this study recommends that the hospital should ensure that losses resulting to inventory shrinkage related to medicines are reduced. This can be done by ensuring that inventory records are accurately kept. The hospital need to manage its inventory investment by ensuring that the right amount of stock is kept at all times.
Neurological and Biological Foundations of Children’s Social and Emotional Development

This article provides an integrated review of the expert literature on developmental processes that combine social, biological, and neurological pathways, and the mechanisms through which these pathways may influence school success and health. It begins with a historical overview of the current understanding of how attachment relationships and social environments influence brain development and plasticity and are, therefore, central to the physical and mental health of individuals and populations. It then expands on the effect of plasticity in relation to behavior and learning at school. This article concludes with a discussion of the role the school nurse may play in supporting health and learning by recognizing signs of relational stress and by advocating for prevention strategies.
Automated Enzymatic Mitochondrial Antibody Assay for the Diagnosis of Primary Biliary Cirrhosis

Abstract Primary biliary cirrhosis is a progressive autoimmune disease that affects middle aged women, resulting in liver cirrhosis. We describe here an automated enzymatic mitochondrial antibody assay adapted for performance on laboratory analysers for the serological diagnosis of primary biliary cirrhosis. This assay detects the characteristic autoantibody directed against the 74kDa E2 subunit of the pyruvate dehydrogenase complex. Analysis of receiver operator characteristic curve data indicated that the automated enzymatic mitochondrial assay procedure discriminated clinically identified patients with primary biliary cirrhosis from normal subjects with a sensitivity of 83% and a specificity of 100%. This method compared favourably against a commercial ELISA method which had a sensitivity of 73% and a specificity of 100%. The automated enzymatic mitochondrial antibody assay is a high throughput assay of use for the routine diagnosis of patients with primary biliary cirrhosis with autoantibodies to the E2 subunit of the pyruvate dehydrogenase complex. The method is of potential value for economical and rapid screening to detect asymptomatic primary biliary cirrhosis in the at-risk segment of the population, namely middle aged women.
The importance of congruence in implementing electronic data interchange systems

Examines the importance of congruence between trading partners, along several dimensions, for the successful implementation of EDI networks. The results of a survey of 64 dyads, drawn from US manufacturing firms and their suppliers, are reported, which suggest that congruence is not a critical factor in determining successful EDI implementation, at least amongst firms operating a “traditional” EDI system, in which the links are direct, rather than via the Internet and where the customer has significant bargaining power.
Consumer attitudes toward marketing strategies over the adult life span

The current study used a grounded theory methodology where in-depth interviews and related literature were integrated to form a process model depicting the evolution of the consumer mindset toward marketing mix strategies (CMSm) over the adult life span. Influences on the evolving CMSm were found to be mainly factors external to the consumer. Marketing forces, that is forces managed by the marketer, were the second most common influence on the CMSm. The model provides a basis for further research to inform marketers on ways to influence consumer behavioural intentions over the consumer's life span.
