Spectrum occupancy measurements in the TV and CDMA bands

Continuous demand, by end users, has become an issue with respect to the scarce resources of the radio frequency spectrum. In this paper we conducted a 24-hour outdoor measurement of spectrum occupancy, in both rural and urban areas in Kwara State, Nigeria, spanning across the frequency range of 48.5 MHz - 880 MHz The results obtained show that the mean average duty cycle for TV bands 1-4 and CDMA band in rural and urban locations are 2.58 % and 12.02% and 0.25% and 3.13% respectively. Findings from this measurements show that there is ample opportunity for deployment of cognitive radio for a more efficient utilization of the spectrum.
DO CHANGES IN DIVIDEND POLICY SIGNAL THE FUTURE OR THE PAST

This research study investigates whether Malaysian Main Board companies pursue changes in dividends to convey information on the future profitability of the companies by studying on a total of 2,679 firm-year observations from year 1998 to 2007. The Ordinary Least Square regression results show that Main Board listed companies do not use dividends as a signalling tool to convey information on the future prospect of the companies. In fact, positive and significant relationship is found to be stronger between changes in dividends in year T=0 with concurrent changes in earnings in year T=0, which is consistent with the previous findings by Benartzi, Michaely and Thaler (1997) and Nissim and Ziv (2001). Further, regression analysis on sub-samples of firm-year observations categorized by the period of stable dividends before the dividend change events (2 years, 3 years and 4 years) shows no relationship exists between the stability of dividends before dividend change events with the extent of dividend signalling. No relationship is found between size of dividend change, size of dividend yield with the extent of dividend signalling. Multiple regression by incorporating industry dummies in the regression equation shows that no difference in changes in earnings between the 3 major sectors (Industrial, Trading/Service and Consumer) when there are changes in dividends, indicating that industry effect does not have any influence on the extent of dividend signalling of the companies.
Gogos, yoyos and dodos: Company directors and industry performance

Summary This research investigates the characteristics of 354 directors of Britain's largest companies. Three sections of independent variables were analysed: those relating to the economic environ; those relating to the domestic environ-family background and educational experiences; those relatinig to self-concept. Directors were categorized according to the econoinic performnance of their industries-GOGOs (industries in growth); YOYOs (industries in turbulence); and DODOs (industries in decline). Several differences emerged between the characteristics of directors and the economic success of their industries for which they were strategically influential. In the past decade, researchers in the field of strategic management have attempted to isolate those factors associated with variations in economic performance. These investigations have developed from two different positions-those from a product-market standpoint, and those which start with organizational formats. Recently, however, Hambrick and Mason (1983) have argued for a third approach; an emphasis upon the values and 'moulding' of those executives who comprise the top management team. It is suggested that the characteristics of this dominant coalition may predict, partially, performance outcomes. This paper adopts the approach of Hambrick and Mason and is based upon data from 354 executive directors of Britain's largest companies, by definition the corporate leaders of the U.K. private enterprise economy. By analysing the economic performance of their industrial and commercial sectors over the previous decade, directors were grouped into categories of growth, decline and turbulence. A review of theoretical and empirical contributions from the areas of strategic management, organizational behaviour and of leadership theory, established hypotheses within three main groups: the economic environ; the domestic environ-education and family background; and those relating to the leaders' self-concept.
Association of Maternal Social Capital with Nutritional Status of 6 to 24-Month-Old Children Living in Urban and Rural Areas in Laguna , Philippines Divine

Introduction: Malnutrition in young children is often viewed as an outcome of the interactions of dietary consumption, socio-economic, and demographic factors. Social capital is a widely explored subject because of its implications on health and socio-economic factors, but has not gained recognition in its role as a determinant of nutritional status. Objectives: The study aimed to determine the association between maternal social capital and nutritional status of 6 to 24-month-old children living in urban and rural areas and to compare the effect of maternal social capital on the child’s nutritional status between an urban and a rural community setting. Methods: A total of 135 randomly selected mothers were interviewed in selected urban and rural communities in San Pablo City and Municipality of Rizal, Laguna, Philippines. Chi-square and Spearman’s test were used to determine the association of variables. Binary logistic regression was used to predict the effect of maternal social capital on nutritional status. Results: Levels of maternal social capital were the same in the urban and rural areas (p=0.24) and had a strong association with household food security (p<0.05). In the urban area, maternal social capital was strongly associated with mother’s education (p<0.01) and weight-for-age (p<0.01) and height-for-age (p<0.05). In the rural area, maternal social capital was strongly associated with mother’s education (p<0.01), ethnicity (p<0.01), marital status (p<0.05) and weight-for-age (p<0.01). Conclusion: There is an association between material social capital and nutritional status. Improvements in education and household food security as well as having parents living-in together may lead to better nutritional outcomes as these factors are associated with maternal social capital which in turn affects nutritional status of children aged 6 to 24 months.

Successful treatment of Behçet’s disease with lenalidomide

tological examination revealed a disparity of fibre diameters, corresponding to scattered atrophic fibres and inflammatory infiltrates in septa. A massive mononuclear inflammatory cell infiltrate was seen in the endomysium, surrounding a capillary. Major histocompatibility complex (MHC) class I was positive in damaged and in intact areas. Pulmonary and digestive investigations did not reveal any anomaly. Carbimazole was stopped as the patient was euthyroid and there was a suspicion of drug-related dermatitis. Without any treatment, within a few weeks the asthenia and arthralgia disappeared. After 3 months, strength testing and muscle-derived enzymes had returned to normal levels and erythema had regressed. Nine months after carbimazole was stopped, the patient was still healthy and neuromuscular examination was normal. The papules on her hand started to decrease. She remains euthyroid. This observation was reported to the pharmacovigilance department and the case was entered in the national drug reactions database. Intrinsic imputability has been assessed as possible (I2), according to the method of Begaud et al. The patient was diagnosed as having JD because she had at least three criteria according to Bohan et al.: symmetrical proximal muscle involvement, elevated muscle-derived enzymes, electromyography changes of inflammatory myopathy. She also had characteristic skin lesions (facial erythema in association with Gottron’s papules). Apart from atrophy and inflammation, histological findings were not entirely specific of dermatomyositis as atrophic fibres were not focused on perifascicular areas, inflammatory infiltrates were seen in septa but also in endomysium, and class I MHC was positive in intact areas of the biopsy. The onset of the symptoms 3 months after the introduction of carbimazole and the rapid resolution after discontinuation of the drug were very suggestive of a causal association. To our knowledge, drug-induced JD has not been reported previously. In contrast, drug-induced dermatomyositis has been reported in adults. The reported drugs were as follows: statins, omeprazole, nonsteroidal anti-inflammatory drugs and D-penicillamine. Several cases of dermatomyositis-like eruption or Gottron’s papules were reported under hydroxyurea. The differential diagnosis of muscle involvement due to hyperthyroidism was excluded in our case as the patient was euthyroid when the symptoms appeared. Dermatomyositis is not a reported side-effect of carbimazole, but related diseases have been described. Shabtai et al. described a case of antithyroid arthritis syndrome due to carbimazole, including myalgia, arthralgia, arthritis, fever and rash. Four adults suffering from myositis associated with carbimazole have also been reported, with only one biopsy-proven case. One patient suffering from carbimazole-induced leukocytoclastic vasculitis has been described. The pathogenesis of carbimazole-related JD is unclear.
Latent Doodle Space

We propose the concept of a latent doodle space, a low‐dimensional space derived from a set of input doodles, or simple line drawings. The latent space provides a foundation for generating new drawings that are similar, but not identical to, the input examples. The two key components of this technique are 1) a heuristic algorithm for finding stroke correspondences between the drawings, and 2) the use of latent variable methods to automatically extract a low‐dimensional latent doodle space from the inputs. We present two practical applications that demonstrate the utility of this idea: first, a randomized stamp tool that creates a different image on every usage; and second, “personalized probabilistic fonts,” a handwriting synthesis technique that mimics the idiosyncrasies of one's own handwriting.
Masculinity Constructs as Protective Buffers and Risk Factors for Men’s Health

This study was designed to replicate the study of Levant, Wimer, and Williams (2011), which reported complex relationships between masculinity and health behaviors using a more diverse sample and updated measures. A sample of 589 college and community-dwelling men responded to an online survey consisting of five scales. Levant et al.’s (2011) study was partially replicated—some masculinity constructs were identified as protective buffers for some health behaviors and others as risk factors. The vast majority of the findings that were replicated were risk factors, suggesting that traditional masculinity is more of risk than a buffer, and occurred in the analyses involving Avoiding Anger and Stress and Avoiding Substance Use subscales, suggesting that these health behaviors are most closely associated with masculinity. The results are discussed in terms of limitations, suggestions for future research, and implications for health care practice.
Incidence and management of bevacizumab-related toxicities in colorectal cancer

Bevacizumab, a recombinant, humanised monoclonal antibody against vascular endothelial growth factor, when used in combination with intravenous 5-fluorouracil (5-FU)-based chemotherapy as first-line treatment of metastatic colorectal cancer (CRC) improves survival. In a randomised, placebo-controlled Phase III study, the addition of bevacizumab to irinotecan/5-FU/leucovorin (IFL) resulted in significant improvement in survival compared with IFL alone, which led to its approval for first-line use in CRC. Bevacizumab also demonstrates improved efficacy in combination with 5-FU/LV over chemotherapy alone when data were pooled from two randomised Phase II studies utilising bevacizumab with 5-FU/leucovorin, and also in a third treatment arm of bevacizumab/5-FU/LV of a randomised Phase III study. More recently, in the second-line setting, bevacizumab in combination with FOLFOX improved survival from 10.8 to 12.9 months in the ECOG 3200 trial. Clinical activity with the addition of bevacizumab to oxaliplatin and either 5-FU or capecitabine-based regimens has also been shown in TREE-2, and activity with the combination of bevacizumab and the EGFR inhibitor cetuximab has been documented in BOND-2. In this study, bevacizumab was generally well-tolerated with no unexpected toxicities when combined with cetuximab. A few toxicities were uniformly encountered in all of the above studies, in particular grade 3 medically-manageable hypertension (3 – 16%). In addition, other toxicities were haemorrhage (2 – 9.3%), gastrointestinal perforation (1.5%), arterial thromboembolism (3.8%), wound healing (1 – 2%) and proteinuria (1 – 2%). As bevacizumab is becoming widely used in general oncology practice, it is important to understand the toxicities which can arise and to develop practice guidelines for their management. This review addresses the toxicities noted in trials using bevacizumab for the treatment of CRC and provides recommendations for toxicity management.
PDEF is a negative regulator of colon cancer cell growth and migration

ETS is a family of transcriptional regulators with functions in most biological processes. Dysregulated ETS factor function leads to altered expression of multiple genes that play critical roles in many of the processes required for cancer progression. While the Ets family gene, prostate‐derived ETS factor (PDEF), is expressed in epithelial tissues including prostate, breast, and colon, PDEF protein expression has been found to be reduced or lost during prostate and breast cancer progression. The goal of this study was to examine the expression and biologic impact of altered PDEF expression in colon cancer. PDEF mRNA and protein are not detectable in several colon‐cancer‐derived cell lines. Re‐expression of PDEF in colon cancer cells inhibits growth and migration. Growth affects are due to altered cellular proliferation, indicated by increased altered cell population in G1 and S phases of the cell cycle, as well as increased apoptosis. Relevant to its modulation of growth and migration phenotypes, PDEF expression resulted in altered expression of genes with established roles in cell cycle, motility, and invasion. Furthermore, chromatin immunoprecipitation studies show that p21 and urokinase plasminogen activator (uPA) are direct PDEF transcriptional targets. While non‐tumor colon epithelium expresses PDEF mRNA and protein, the majority of tumors showed decreased mRNA and/or protein expression. In human tumor tissue samples, PDEF expression was inversely correlated with the expression levels of uPA. Collectively, the data support the model that PDEF is a negative regulator of tumor progression by modulating the expression of growth and migration promoting genes. J. Cell.

The predicting role of substance P in the neoplastic transformation of the hypoplastic bone marrow

Aims: To estimate the expression of substance P in the haematopoietic cells of hypoplastic bone marrow and define its relationship with the course of bone marrow hypoplasia. Methods: Bone marrow specimens were obtained from 42 children with bone marrow hypoplasia who were hospitalised in the Department of Pediatric Oncology, Hematology and Transplantology, Poznan University of Medical Sciences, Poznan, Poland, between 1996 and 2003. Substance P and Ki-67 expression were evaluated using immunochemical and hybridocytochemical assays. Results: The expression of substance P (as evidenced by both immunocytochemical and hybridisation techniques) was confirmed in the cytoplasm of B lymphocytes in 8 of 11 children who developed acute leukaemia in 45 (SD 12) days. The percentage of substance P-positive cells ranged from 67.6 to 95.8 (mean of 81.5% cells with immunocytochemistry and 84.3% with in situ hybridisation). The risk of development of leukaemia secondary to bone marrow hypoplasia was found to be significant (p<0.001) in those children who expressed substance P in normal-looking lymphocytes at the initial bone marrow evaluation. Conclusions: The presence of substance P in B lymphocytes of hypoplastic bone marrow may predict its neoplastic transformation. A marked correlation between substance P-positive bone marrow pattern and the expansion of tumour cells may prove the potential value of this oligopeptide in the pathogenesis of leukaemia.
Analysis of Newspaper Coverage of Food Security through a Disability Studies Lens

Food security is an issue of global concern recognized by numerous international and national agencies. It has been mentioned over twenty times in the Rio+20 outcome document The Future We Want. It is recognized as an essential human security by the World Health Organization Commission for Human Security and as a social determinant of health. Food security agendas are enacted in many places locally to globally. Media are to inform the public on issues of importance for the public. Disabled people are part of the public and disabled people are one group experiencing over proportional levels of food insecurity. We investigated the food security coverage of various newspapers through a disability studies lens. To obtain quantitative data on the visibility of disabled people and other groups in the food security discourse the following newspapers were investigated: The Globe and Mail (Canada), National Post (Canada), Calgary Herald (Canada), New York Times (USA), The Guardian (UK), The Times (UK), and the Canadian Newsstand complete, a collection of 300 Canadian newspapers. Quantitative and qualitative data on what food security issues were reported was obtained from The Globe and Mail (Canada), Calgary Herald (Canada) and the New York Times (USA). We discuss how issues reported around food security are influenced by disabled people and how they could impact disabled people. We found very little to no mentioning of disabled people within food security coverage. Our data also reveals the absence of coverage of other socially disadvantaged groups such as indigenous people and immigrants and a lack of a human rights or ethics angle. We posit that many of the food security problems mentioned are of relevance to and experienced by disabled people and other socially disadvantaged groups such as indigenous people and immigrants however the reader won’t make the linkage by reading the newspapers we investigated. We conclude that the utility of the newspapers covered in advancing food security for disabled people and other socially disadvantaged groups is very low.
The Effectiveness and Independence of Supervisory Board: Evidence from China 2000-2009

This paper examines the effectiveness and the independence board by using all firms listed on the main board of China from 2000 to 2009. I find significant inverse relationship between supervisory board size and firm performance. In addition, I find evidence of a significant nonmonotonic relationship, Tobin's Q and ROA first decline and then increase as the independence of supervisory board rises. The results are consistent with prior studies.
Factors that affect online consumer trust in taiwan (china)

According to Internet's rapid development, electronic commerce becomes a new way for businesses to market products online. Many people like shopping online because of the convenience. However, when consumers shop online, some concerns emerge, such as worries of how personal data will be used, how secure the online site is, and whether or not the Website should be trusted. The topic was explored in this dissertation was the identification of the factors that affect online consumer trust among Taiwanese Internet shoppers. This is a practical concern occurring on the Internet worldwide. Therefore, how to increase confidence and trust is imperative to online shoppers and sellers. This dissertation found that perceived online security, perceived online privacy, Internet experience, and third-party assurance seal are positively associated with online consumer trust, and perceived risk is negatively associated with online consumer trust. In addition, there is no difference between Taiwanese male and female online shoppers on the issue of online consumer trust, nor is there a difference between Taiwanese single and married online consumers on the issue of online consumer trust. The researcher recommends future studies should utilize a probability sampling method, focus on experimental research design to measure the difference among this study and this proposed study, and adopt a qualitative research design by interviewing participants and eliciting their opinions about online consumer trust.
Corporate Financial Reporting on the Internet: Evidence from Bangladesh

This research paper investigates the utilization of the Internet for communicating financial information by the listed companies of Bangladesh, a developing country. The sample for the study consists of 268 companies listed on the stock exchanges (the Dhaka Stock Exchange and the Chittagong Stock Exchange) of Bangladesh. Corporate websites of the sample companies were browsed by using a standard web browser for collecting data relating to corporate reporting on the Internet. On-line financial reporting in Bangladesh is still in its infancy. Only 104 (38.81 percent) of the 268 companies have a website and only 64 companies (61.54 percent) disclose at least one financial item. A scoring scheme has been developed to measure the level of on-line financial reporting. A wide variation in the level of on-line financial reporting across 15 sectors has been found. It also ranks different sectors of companies based on their reporting scores. The highest-ranking sector was the Banking, Leasing & Finance sector. This paper adds to the existing body of literature on on-line financial reporting studies by exploring on-line financial reporting practices of Bangladesh, a developing country.
