Social Work Conditions Affecting Teachers Productivity For Secondary Education Goal Attainment In Delta State, Nigeria

The study dealt with social conditions of work affecting teacher’s productivity for secondary educational goal attainment in Delta State. Analytical survey design was adopted for the study. The population for the study was 8,610 teachers in public secondary schools in Delta State. This comprised 3,803 male teachers and 4,807 female teachers as well as 5,550 urban and 3,060 rural teachers. The sample for the study was1245 teachers (568 male and 677 female; 805 urban and 440 rural). The sample size was 15% of the population and the sampling technique adopted for the study was stratified random sampling technique. A 12-items questionnaire titled “Social Work Conditions and Teachers Productivity Questionnaire” (SWCTPQ) was used for data collection. The questionnaire was responded to on a four point modified likerttype scale of Strongly Agreed (SA) = 4 points; Agreed (A) = 3 points; Disagree (D) = 2 points; and Strongly Disagree (SA) = 1 point. The questionnaire was validated by two experts in Measurement and Evaluation in the Department of Psychology, Guidance and Counseling. Faculty of Education, University of Port Harcourt. The reliability index was determined using Cronbach Alpha with a coefficient of 0.72. Data for the study was collected by the researcher with the aid of two trained Research Assistants. Mean and Standard Deviation was used to answer the research questions while z-test was used to test the hypotheses. The findings of the study revealed that performance appraisal, participatory decision making, challenging job and interpersonal relationship exists in these schools while special assistance and security were absent. It was therefore recommended that special assistance such as provision of accommodation should be provided for teachers to increase their level of productivity as well as a safe working environment.
64 Year‐Old Woman with Longstanding Migraine

A previously healthy 64 year-old woman was admitted to ourhospital complaining of generalized fatigue, sleep impairment,mild weight loss and a chronic progressive headache, that becameholocranial and resistant to many drugs during last few months.The patient was alert and orientated. No papilledema but slightlyneck stiffness was noted. Cranial nerve functions were intact.Initial CT of the brain and spine did not show any remarkablealteration. In a posterior MRI, after gadolinium administration, aleptomeningeal enhancement was identiﬁed. Biochemical andcytological Light Chain Ratio (LCR) study was unremarkable.Because of the possibility of chronic tuberculous meningitis andwhile waiting for LCR culture, she underwent antituberculostatictreatment.However,nogrowthwasdetectedinanyofthebacterialcultures of the LCR.

Effects of Ego Networks and Communities on Self-Disclosure in an Online Social Network

Understanding how much users disclose personal information in Online Social Networks (OSN) has served various scenarios such as maintaining social relationships and customer segmentation. Prior studies on self-disclosure have relied on surveys or users' direct social networks. These approaches, however, cannot represent the whole population nor consider user dynamics at the community level. In this paper, we conduct a quantitative study at different granularities of networks (ego networks and user communities) to understand users' self-disclosing behaviors better. As our first contribution, we characterize users into three types (open, closed, and moderate) based on the Communication Privacy Management theory and extend the analysis of the self-disclosure of users to a large-scale OSN dataset which could represent the entire network structure. As our second contribution, we show that our proposed features of ego networks and positional and structural properties of communities significantly affect self-disclosing behavior. Based on these insights, we present the possible relation between the propensity of the self-disclosure of users and the sociological theory of structural holes, i.e., users at a bridge position can leverage advantages among distinct groups. To the best of our knowledge, our study provides the first attempt to shed light on the self-disclosure of users using the whole network structure, which paves the way to a better understanding of users' self-disclosing behaviors and their relations with overall network structures.
Towards a uniform definition for the centralisation phenomenon

The focus of this PhD project is on symptom centralisation. Its primary objectives were to establish a standard operational definition of centralisation and evaluate its inter-rater reliability in neck pain. Two systematic reviews on the reliability and prognostic value of clinically induced symptom responses in spinal pain (Chapters 2 and 3) showed that although the potential usefulness of centralisation has been demonstrated in low back pain, concern has been expressed about the observed inconsistency in reported definitions, and the scarcity of studies in neck pain. A Delphi survey of experts (Chapter 4) assisted in the development of a uniform operational definition for centralisation and the identification of future research questions. Centralisation was generally defined as the progressive and stable reduction of the most distal presenting pain towards the spine midline in response to standardised spinal loading strategies. The support by the Delphi panel of a broader definition allowed for a multitude of different ways of testing to be included in the assessment procedure which may offer some flexibility to clinicians assessing, classifying and managing different spinal pain presentations across different countries. Although the reliability of identifying centralisation was acceptable, high levels of reliability were not demonstrated (Chapter 5). However, reliability was greater for the pair of physiotherapists with prior experience and formal extensive training in symptom response assessment. Therefore, the optimal type and amount of training for eliciting and interpreting centralisation and the effect of procedural variations on testing the outcomes of individuals who centralise require urgent investigation. The prognostic and management value of centralisation are also unknown. This investigation may pave the way for the standardisation of centralisation as a physical sign and stimulate interest for further study of potential sub-groups and classification of spinal syndromes.
Curcumin exhibits therapeutic effect against spinal cord injury via inhibition of neuronal inflammation and apoptosis

Purpose: To investigate the effect of curcumin on spinal cord injury (SCI) in a rat model. Methods: SCI was induced in the rats using mid thoracic spinal cord compression, after which curcumin was injected intraperitoneally. Western blotting was used for assay of expressions of apoptotic proteins, viz, IL-1β, NF-κB p65, TLR4, TNF-α, LC3, Bax and Bcl-2. Malondialdehyde (MDA) and myeloperoxidase were measured using standard methods. Neuronal loss in spinal cord tissues was determined with TUNEL staining and NeuN labelling. Results: Curcumin treatment significantly (p < 0.05) suppressed SCI-mediated upregulation of myeloperoxidase activity and increase in MDA level in rat spinal cord. The reduction of glutathione (GSH) and superoxide dismutase (SOD) activities in the spinal cord of SCI rats were suppressed by curcumin treatment. Curcumin treatment also led to a significant (p < 0.02) increase in the proportion of NeuN positive cells and marked reduction in TUNEL positive cells, but it decreased caspase-3 in the spinal cord tissues of SCI rats. Moreover, curcumin reversed the effect of SCI on protein expressions of Bax and Bcl 2 in a dose-based manner. There was marked curcumin-induced decline in CD11b and GFAP levels in the spinal cord tissues of the SCI rats. Conclusion: These results demonstrate that curcumin protects rats against SCI via inhibition of oxidative stress-mediated neuronal apoptosis. Therefore, curcumin may be useful for the development of an effective treatment for spinal cord injury.
Biological activities of Cretan Salvia pomifera extracts

: The polyphenolic content and biological activities of dichloromethane, chloroform, ethyl acetate, and ethanol extracts of Cretan Salvia pomifera L. (Lamiaceae) were analysed. The ethyl acetate extract showed the highest content of total phenolics and total flavonoids. The ethanol extract exhibited the highest activity in the DPPH and FRAP assays, while the dichloromethane extract had the highest activity in the ABTS test. The ethyl acetate extract showed the highest activity in the β-carotene-linoleic acid system. The antioxidant activity of extracts was positively correlated with the total content of phenolics. Extracts demonstrated weak antibacterial activity. The ethyl acetate extract had the highest acethylcholinesterase inhibition at 50 μg/ mL, while the ethanol and dichloromethane extracts showed the highest activity of tyrosinase inhibition at 25 μg/mL. In view of the significance of antioxidants in prevention and treatment of neurological diseases, the noticeable antioxidant and anti-neurodegenerative effects of the ethanol and ethyl acetate extracts recorded in this study make further research on S. pomifera seem promising .
EVIDENCE BASED VETERINARY

We studied the antimicrobial use in 227 pig herds originating from 4 European countries (Belgium, France, Germany, Sweden) and its association with animal health, production, biosecurity and other disease prevention measures. Huge differences in antimicrobial use, ranging from excessively high to remarkably low, were observed within and between countries with an average treatment incidence from birth till slaughter of 243 in Germany (42 for the sows), in Belgium 143 (16 for sows), in France 108 (22 for sows) and in Sweden 23 (11 for sows). As the biosecurity is concerned, Sweden had on average the highest total biosecurity status (63.7), followed by Germany (63.0), France (58.6) and Belgium (57.8) In all countries external biosecurity (measures taken to prevent disease introduction) scored higher compared to internal biosecurity (measures taken to prevent within herd disease transmission) which has been observed in previous studies. It was found that antimicrobial usage in sows was significantly associated with the antimicrobial usage from birth till slaughter in the growers, the use of anti-inflammatory products in weaners and the number of pathogens vaccinated against, suggesting an overall higher disease pressure. Higher antimicrobial usage from birth till slaughter was associated with a shorter farrowing rhythm and a younger weaning age, whereas a better external biosecurity was related with a lower antimicrobial usage. A higher external biosecurity was associated with more weaned piglets per sow per year. Based upon the available data “44 top farmers” were identified that managed to combine both below national average usage of antimicrobials and above national average technical performances. These farmers were characterized by an on average higher internal biosecurity status and were generally located in a more favorable environment (lower pig density and limited contact with wildlife). They also treated less frequently against respiratory clinical symptoms in weaners and finishers. Overall the study showed high variation both in antimicrobial usage, biosecurity and management practices indicating substantial room for improvement. Moreover some cross country associations were identified allowing for potential interventions such as using a longer farrowing rhythm, weaning of the piglets at an older age and improvement of the biosecurity status. At the same time, the improved biosecurity is expected to result in improve technical performances. INTRODUCTION The global development and spread of antimicrobial resistance is largely driven by the extensive use of antimicrobials both in human and animal medicine. In a recent study, data on sales of antimicrobials for food-producing animals were compared to data on antimicrobial resistance, and a clear association between use and resistance was found (Chantiziaris et al., 2013). The ESVAC reports have shown that there are vast differences between countries in amounts of antimicrobials sold for food-producing animals (Esvac 2012, grave et al., 2014), but these data do not provide insight on how sales are distributed by species and age groups.
THE THEORY OF CAPITAL STRUCTURE FROM ISLAMIC PERSPECTIVE, AND THE ROLE OF SUKUK

For the past fifty years after the influential irre levance theory of Modigliani and Miller (1958) on capital s tructure, academicians debate rigorously on the theory of cap ital structure. However, the number of literatures fo cusing on corporate finance from the view point of Islamic pe rspectives is not large. The objective of this paper is to examin e the theory of capital structure from the Islamic point of view . Here we do literature review on Islamic scholars thought on th e theory, and subsequently discuss the implication of sukuk on ca pital structure as indicated by tradeoff, agency cost and pecking order theory .
Vote-Counting Method to Obtain an Estimate and Confidence Interval for the Population Correlation Coefficient Using SASI AFo

In today's information age, scientific studies are being conducted at an exponential rate in areas such as psychology, pharmaceutics, and education. The metaanalyst wants to combine these studies which investigate a common phenomenon into useful information. However, missing values pose a particularly difficult problem in meta-analysis. This paper will provide a solution, vote-counting procedures, to estimate the population correlation coefficient when some of the studies do not provide the information about the sample correlation coefficient. SASI AF was used in the development of an interactive application system for calculating and displaying the confidence interval for the population correlation coefficient.
Using the NADA Protocol to Improve Wellbeing for Prostate Cancer Survivors: Five Case Studies

This paper presents case studies of five men diagnosed and treated for prostate cancer, who participated in a project to assess the potential for using the NADA ear acupuncture protocol to improve wellbeing. Selected for their diversity, they illustrate the range of diagnoses, treatments, and associated bothersome symptoms experienced by prostate cancer survivors. They also illustrate the variety of ways that NADA acupuncture in a group setting can contribute to overall wellbeing. Examining the progress of these individuals through treatment provides valuable insights into the effects of NADA treatment. These cases may influence perceptions of clinicians, patients, acupuncturists and funders about NADA’s potential role in the ongoing support of men with cancer of the prostate. They also suggest that future research is warranted.
Tensor-Based Resource Utilization Characterization in a Large-Scale Cloud Infrastructure

The introduction of virtualization and cloud computing has enabled a large number of containers/virtual machines to share computing resources. Nevertheless, the number and size of data centres are still on the rise, partly on account of an ever increasing amount of generated data and workloads worldwide. On the other hand, independent studies indicate that a large number of servers in contemporary data centres are underutilised. One of the strategies currently adopted by the research community in order to deal with resource inefficiency is dynamic workload consolidation. The idea behind is dynamically balancing the supply of computing, communication, and storage resources with the demand for resources. This entails populating physical servers with an optimal number of complementary workloads. Most existing or proposed approaches employ multi-variate optimisation to achieve this goal but do not easily lend themselves to fast and intuitive solutions. In this paper, we investigate the scope and usefulness of dimensionality reduction techniques (tensor decomposition) to identify execution and resource utilisation patterns in hosted containers/virtual machines. Our analysis is based on two large-scale data centres, one of them hosts 1190 commercial virtual machines on 59 physical computing servers and 29 physical storage servers organised in 9 clusters and the other 44373 containers on 3985 physical servers. Our analysis shows that spatial and temporal patters can be uncovered with tensor decomposition, based on which efficient clustering can be realised.
User Security in Cloud Using Password Authentication

Cloud computing technology is an open standard, service-based, Internet-centric, safe, convenient data storage and network computing services [8]. Cloud computing is an internet based model for enabling convenient, on demand network access to a shared pool of configurable computing resources [9]. The software and data that you access for your work doesn‟t exist on your computer instead it‟s on the server. This concept of using services not stored on your system is called Cloud Computing. In this paper, we are implementing a technique to enhance the security of cloud. We create an algorithm based on the selection of username and generate a password to strengthen the security in cloud.

GENERATION OF SILK FIBROIN-CA-P COMPOSITE BIOMIMETIC BONE REPLACEMENT MATERIAL USING ELECTROCHEMICAL DEPOSITION

Mineralized natural protein based novel bone replacement materials are investigated for tissue engineering. Mineralized silk fibroin composite foams and films display excellent biocompatibility. In this study, the biomimetic and electrochemical mineralization of orderly oriented silk fibroin scaffolds was studied. Commercially obtained pure silk woven fabric was boiled in 0.02 M Na 2 CO 3 for 20 min. Calcium phosphate was deposited at 37°C for twenty minutes in seven sequential immersion steps, using 250 mM CaCl 2 2H 2 O and 120 mM K 2 HPO 4 , containing 0.15 M NaCl and 50mM TRIS-HCl, pH 7.4, followed by electrochemical treatment in modified SBF solution at 40°C at a current density of -25mA/cm 2 for 60 min. The amount of biomimetically deposited Ca-P increased with the number of immersion steps. SEM images and XRD analysis of the Ca-P deposit indicated the initial formation of brushite with its monoclinic crystal structure and characteristic peak at 11.76 2θ, and electrochemical conversion of brushite to hydroxyapatite on silk after electrochemical cathodization as confirmed by XRD and SEM analysis. Thus, a silk-fibroin-hydroxyapatite composite material prepared as a xenograft consisting of biocompatible components, and easily prepared as an economical bone segment replacement material with highly oriented fibers.
S4G: Amodal Single-view Single-Shot SE(3) Grasp Detection in Cluttered Scenes

Grasping is among the most fundamental and long-lasting problems in robotics study. This paper studies the problem of 6-DoF(degree of freedom) grasping by a parallel gripper in a cluttered scene captured using a commodity depth sensor from a single viewpoint. We address the problem in a learning-based framework. At the high level, we rely on a single-shot grasp proposal network, trained with synthetic data and tested in real-world scenarios. Our single-shot neural network architecture can predict amodal grasp proposal efficiently and effectively. Our training data synthesis pipeline can generate scenes of complex object configuration and leverage an innovative gripper contact model to create dense and high-quality grasp annotations. Experiments in synthetic and real environments have demonstrated that the proposed approach can outperform state-of-the-arts by a large margin.
DOES MANDATORY AUDIT FIRM ROTATION ENHANCE AUDITOR INDEPENDENCE? EVIDENCE FROM SPAIN*

In this study, we document evidence on the impact of mandatory rotation of audit firms on auditor independence using Spanish archival data. Rotation of audit firms every nine years was mandatory in Spain from 1988-1995. Although the rule was never enforced, the Spanish context provides a unique setting to examine the effects that mandatory audit firm rotation has on auditor’s behavior. We examine audit reports for a sample of financially stressed companies from 1991-2000 to compare auditors’ reporting behavior in a regime with rotation (mandatory rotation period: 1991–1994) and one without rotation (post-mandatory rotation period: 1995–2000). We find no evidence to suggest that a mandatory rotation requirement is associated with a higher likelihood of issuing going-concern opinions. We test two competing hypotheses concerning the impact of mandatory rotation on the likelihood of auditors’ issuing going-concern modified audit opinions. Our results suggest that auditors’ incentives to protect their reputation positively impact on the likelihood of issuing going-concern opinions, while auditors’ incentives to retain existing clients did not impact on their decisions in both the mandatory rotation and post-mandatory rotation periods. Overall, our results provide empirical support for the arguments put forward by opponents of mandatory rotation.
GAN Priors for Bayesian Inference

Bayesian inference is used extensively to infer and to quantify the uncertainty in a field of interest from a measurement of a related field when the two are linked by a mathematical model. Despite its many applications, Bayesian inference faces challenges when inferring fields that have discrete representations of large dimension, and/or have prior distributions that are difficult to characterize mathematically. In this work we demonstrate how the approximate distribution learned by a generative adversarial network (GAN) may be used as a prior in a Bayesian update to address both these challenges. We demonstrate the efficacy of this approach by inferring and quantifying uncertainty in a physics-based inverse problem and an inverse problem arising in computer vision. In this latter example, we also demonstrate how the knowledge of the spatial variation of uncertainty may be used to select an optimal strategy of placing the sensors (i.e. taking measurements), where information about the image is revealed one sub-region at a time.
