THE PROFILE OF PATIENTS WITH SCHIZOPHRENIA WHO ATTEMPTED SUICIDE

Abstract: Introduction: Suicide is a complex phenomenon, and deliberate act of taking one’s own life, associated with numerous and various biological, social and psychological factors. It is an important psychopathological entity and one of the most demanding clinical problems, which psychiatrists face in their everyday practice, especial in schizophrenic patients. According to literature data, the number of suicides of schizophrenic patients has been increasing in recent decades Objectives: The aim of this study was to determinate the profile of patients with schizophrenia who attempted suicide in the Psychiatric hospital “Skopje”-Skopje, R.Macedonia. Methods: The study included 114 patients with schizophrenia, 47.4% (n=54) of them attempted suicide, 52.6 %( 60) was group consists of patients with schizophrenia who is not registered for suicide attempt, nor the existence of suicide idea. Psychiatric diagnosis of schizophrenia was based on ICD-10 criteria. Results: Based on the investigation of patients with schizophrenia who attempted suicide, we obtained a typical profile as follows: middle-aged person(31.4 average years), single (61,1% were not married, 44.4% live alone), (79.5%) unemployed, repeatedly hospitalized and history of suicide attempts, attempting suicide using a violent method (poisoning -55.5%, drowing-7.4%, hanging-9.2%, slashing their wrists-16.6%, jumped from height-5.5% etc.) after more than tree weeks of hospital treatment and out of hospital.
Chapter 1 Trade integration , production networks and the services sector : implications for regional trade agreements in Eastern and Southern Africa

Regional economic integration in Eastern and Southern Africa has been beset for years by problems relating to overlapping membership of sub-Saharan African regional groupings, lack of political will and institutional capacity, and tensions between intra-African (SACU, SADC, COMESA) agreements and trade agreements concluded either individually or collectively with extra-continental countries or blocs (such as the SA-EU TDCA, SACU-US FTA negotiations, AGOA and the ongoing EPA discussions with the EU). SACU itself has been involved in Free Trade Agreement (FTA) negotiations on several fronts, as well as multilateral trade discussions under the auspices of the WTO.
Persistency of Excitation for Robustness of Neural Networks

When an online learning algorithm is used to estimate the unknown parameters of a model, the signals interacting with the parameter estimates should not decay too quickly for the optimal values to be discovered correctly. This requirement is referred to as persistency of excitation, and it arises in various contexts, such as optimization with stochastic gradient methods, exploration for multi-armed bandits, and adaptive control of dynamical systems. While training a neural network, the iterative optimization algorithm involved also creates an online learning problem, and consequently, correct estimation of the optimal parameters requires persistent excitation of the network weights. In this work, we analyze the dynamics of the gradient descent algorithm while training a two-layer neural network with two different loss functions, the squared-error loss and the cross-entropy loss; and we obtain conditions to guarantee persistent excitation of the network weights. We then show that these conditions are difficult to satisfy when a multi-layer network is trained for a classification task, for the signals in the intermediate layers of the network become low-dimensional during training and fail to remain persistently exciting. To provide a remedy, we delve into the classical regularization terms used for linear models, reinterpret them as a means to ensure persistent excitation of the model parameters, and propose an algorithm for neural networks by building an analogy. The results in this work shed some light on why adversarial examples have become a challenging problem for neural networks, why merely augmenting training data sets will not be an effective approach to address them, and why there may not exist a data-independent regularization term for neural networks, which involve only the model parameters but not the training data.
Mediating roles of intrinsic motivation and self-efficacy in the relationships between perceived person-job fit and work outcomes

Most fit scholars primarily focused on the direct relationship between perceived person-job fit and work-related outcomes. However, they offered little understanding of the mediating process linking these relationships. Hence, the present study specifically considered intrinsic motivation and self-efficacy as the mediating variables. After analyzing 256 sets of employee and supervisor questionnaires collected from 12 frozen seafood processing factories in Taiwan, this study found that perceived person-job fit was directly related to job involvement and job performance. In addition, it was also found that both intrinsic motivation and self-efficacy served as important mediating and motivational mechanisms in the relationship between perceived person-job fit and job involvement, as well as those between perceived person-job fit and job performance. Implications for practice were discussed and directions for future research were also provided. Key words: Person-job fit, intrinsic motivation, self-efficacy, job involvement, job performance.
Does Twitter matter? The impact of microblogging word of mouth on consumers’ adoption of new movies

This research provides an empirical test of the “Twitter effect,” which postulates that microblogging word of mouth (MWOM) shared through Twitter and similar services affects early product adoption behaviors by immediately disseminating consumers’ post-purchase quality evaluations. This is a potentially crucial factor for the success of experiential media products and other products whose distribution strategy relies on a hyped release. Studying the four million MWOM messages sent via Twitter concerning 105 movies on their respective opening weekends, the authors find support for the Twitter effect and report evidence of a negativity bias. In a follow-up incident study of 600 Twitter users who decided not to see a movie based on negative MWOM, the authors shed additional light on the Twitter effect by investigating how consumers use MWOM information in their decision-making processes and describing MWOM’s defining characteristics. They use these insights to position MWOM in the word-of-mouth landscape, to identify future word-of-mouth research opportunities based on this conceptual positioning, and to develop managerial implications.
Inflammatory Biomarkers And Endothelial Dysfunction Among Obese Type 2 Diabetic Patients: A Correlational Study

Background:The vascular complications of diabetes mellitus impose a huge burden on the management of this disease. Inflammation is one of the major factors in the formation of endothelial dysfunction. Endothelial dysfunction is a major contributor to the complications of diabetes mellitus.Objective:The aim of the present study was to investigate the possible relationship between inflammation and endothelial dysfunction in obese type 2 diabetic patients.Material and Methods:Forty obese type 2 diabetic patients (24 males and 16 females) with body mass index (BMI) ranged from 31 to 35 Kg/m2, non-smokers, free from respiratory, kidney; liver, metabolic and neurological disorders were recorded in this study. Their age ranged from 40 to 55 years were included in this study as the first group (A). While a forty non-diabetic subjects (23 males and 17 females) not suffering of any disease, their age ranged from 40 to 52 years were included in this study as the second group (B) and considered as a control group.Results:Diabetic patients showed significantly higher values of TNF-α, IL-6, CRP, HBA1c, ICAM-1, VCAM-1 and E-selectin in comparison to controls. Also, there was significant positive correlation between inflammatory and endothelial dysfunction biomarkers among obese diabetic patients.Conclusions:There was a strong association between elevated biomarkers of inflammation and endothelial dysfunction among type 2 diabetic patients.
Does Calendar Time Portfolio Approach Really Lack Power

This paper investigates whether the calendar time methodology lacks power in detecting the long-run abnormalperformance of the firms after major corporate events. In addition, the study proposes a variant of calendar timeapproach by standardizing the abnormal returns of the event firms forming the monthly portfolios. To assess therobustness of the modified method, the results from buy-and-hold abnormal return approach and the meanmonthly calendar time abnormal return method are also reported. The empirical analysis documents that theproposed approach improves the power in random samples and in samples with small firms and with calendarclustering.
Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure

The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels. Two levels of nitrogen (75 and 150 kg/ha) and one control without fertilization associated to three initial deferring heights (20, 30, and 40 cm) were evaluated. The design was of completely randomized blocks with three replications in a subdivided plot scheme. A raise in the initial deferment height and in the fertilization elevated the sward and extended tiller heights, the leaf area index, and the light interception by the sward. The piata palisadegrass deferred with an initial height of 40 cm presented a higher forage mass with lower percentage of leaf blades, and higher stem and dead tissue quantity. Additionally, this management strategy resulted in lower bulk density of leaf blade and in higher bulk densities of stems and dead tissue. The utilization of 150 kg/ha of nitrogen raised the production and the bulk density of deferred piata palisadegrass forage and increased production and bulk density of leaves and stems. In the region of Vicosa, Minas Gerais, the piata palisadegrass deferred with an initial height of 30 cm and fertilized with 75 kg/ha of nitrogen in the beginning of the fall presents adequate mass and structure to animal production in the winter.
Aalborg Universitet Segmentation of RGB-D indoor scenes by stacking random forests and conditional random

Depth images have granted new possibilities to computer vision researchers across the field. A prominent task is scene understanding and segmentation on which the present work is concerned. in this paper, we present a procedure combining well known methods in a unified learning framework based on stacked classifiers; the benefits are two fold: on one hand, the system scales well to consider different types of complex features and, on the other hand, the use of stacked classifiers makes the performance of the proposed technique more accurate. The proposed method consists of a random forest using random offset features in combination with a conditional random field (CRF) acting on a simple linear iterative clustering (SLIC) superpixel segmentation. The predictions of the CRF are filtered spatially by a multi-scale decomposition before merging it with the original feature set and applying a stacked random forest which gives the final predictions. The model is tested on the renown NYU-v2 dataset and the recently available SUNRGBD dataset. The approach shows that simple multimodal features with the power of using multi-class multi-scale stacked sequential learners (MMSSL) can achieve slight better performance than state of the art methods on the same dataset. By using MMSSL, the method shows good improvements on the major performance metrics compared to the base models and this displays that the method is effective in this problem domain. c © 2016 Elsevier Ltd.

Behavioral Intention Perceived Usefulness Perceived Ease of Use Behavioral Intention Perceived Enjoyment Perceived Usefulness Perceived Ease of Use Perceived Fee Behavioral Intention Perceived Enjoyment Perceived Usefulness Perceived Ease of Use Prior Experience

Rapid advancements in information and communication technologies (ICT) have allowed people some opportunities to access digitalized contents without restrictions in time or place. Mobile data service (MDS) is an important emerging ICT, thus many studies on information systems (IS) and marketing examine key predictors of MDS user behaviors. However, although the usage-based pricing of MDS is considered as a unique feature, most studies on MDS have paid little attention to its influences on MDS user behaviors. This study proposes a theoretical framework integrating perceived fee into Van der Heijden’s model to understand the role of perceived fee in wireless pay-per-use services. To capture the moderating effect of prior experience, this study also investigates the differences in determinants for the adoption decision stages and the continued usage decision stages. The proposed model is empirically tested by using survey data collected from 149 inexperienced users and 393 experienced users. The findings indicate that, compared with traditional IS such as a corporate IS and a website, perceived fee explains a large portion of the variances in adoption intention and continued usage intention toward MDS. This study also reveals that the antecedents leading to MDS user behavior vary in terms of prior experience. Finally, theoretical and practical implications of this study are described. 2008 Elsevier Ltd. All rights reserved.
Market Timing of New Equity Offerings: Evidence from Chinese Listed Firms

A well-established paradigm of the developed financial market is that firms take advantage of market valuations to make financial decisions. Do firms operating in a highly controlled market follow similar financial strategies? We find that the new equity offerings of Chinese listed firms are strongly associated with market valuations. However, the market timing effectiveness is relatively lower in the firms owned by the State and in the time when firms conduct non-tradable share reform by liquidating non-tradable shares. We also find that the proceeds from equity offerings are expended more in the form of opportunistic and discretionary usage than investment requirements. Our empirical evidence supports the general applicability of the equity market timing theory to the highly controlled emerging market of China.
Surfaces over a p-adic field with infinite torsion in the Chow group of 0-cycles

We give an example of a projective smooth surface X over a p-adic field K such that for any prime ` different from p, the `-primary torsion subgroup of CH0(X), the Chow group of 0-cycles on X, is infinite. A key step in the proof is disproving a variant of the Bloch-Kato conjecture which characterizes the image of an `-adic regulator map from a higher Chow group to a continuous etale cohomology of X by using p-adic Hodge theory. With the aid of the theory of mixed Hodge modules, we reduce the problem to showing the exactness of the de Rham complex associated to a variation of Hodge structure, which is proved by the infinitesimal method in Hodge theory. Another key ingredient is the injectivity result on the cycle class map for Chow group of 1-cycles on a proper smooth model of X over the ring of integers in K, due to K. Sato and the second author.
ISOLATION AND SCREENING OF BACTERIA FROM Zea mays PLANT GROWTH PROMOTERS

Plant growth promoting rhizobacteria is a beneficial microbe colonizing plant roots, which enhances crop productivity and offers an attractive way to replace chemical fertilizers, pesticides, and supplements. In Mexico, the corn (Zea mays L.) is an important annual gramineae crop with a high volume of global production because of the favorable environmental and socioeconomic situation. In this study the isolation of new strains of bacteria under different environmental conditions will enable further research avenues to better use the capacities of root-colonizing bacteria in agricultural production systems. The strains isolates were analyzed for five plant-growth-promoting attributes: N fixation, solubilization of phosphate, production of auxins, siderophores and gibberellins. The identification of bacterial isolates was determined by biochemical assays and VITEK2 Compact (bioMérieux). A total of 143 morphologically distinct rhizobacteria from corn crops of three communities of Guerrero, Mexico, were isolated, and 54 effective multi trait rhizobacteria were found. It was determined that the bacterial isolates are related to Pseudomonas, Enterobacter, Serratia, Pantoea, Staphylococcus, Klebsiella, Burkholderia, Salmonella, Proteus, Acinetobacter, Citrobacter and Streptoccoccus genus. This collection represents the first bank of multi trait activity in Mexico, and it will contribute to future studies as biomolecules for promoting early emergence and growth of the seeds.

Examining Faculty Motivations for Engagement in Service-Learning at a Faith-Based Institution: A Comparison of Service-Learning Faculty versus Non-Service-Learning Faculty

﻿Faculty in a faith-based university were examined on motivations and deterrents for engagement in service-learning. Service-learning and non-service-learning faculty were compared based on rank, gender, discipline, and denominational affiliation. Findings suggest motivations and deterrents for faculty engaging in service learning in faith-based universities are similar to those faced by faculty in non-faith-based universities. Although no specific faith-based deterrents emerged from the study, unique faith motivating factors were identified.
Re : Cursiefen et al . : Aganirsen antisense oligonucleotide eye drops inhibit keratitis-induced corneal neovascularization and reduce need for transplantation : the I-CAN study

Dear Editor: In their article, Cursiefen et al present a phase III clinical trial evaluating the therapeutic potential of eye drops containing a relevant oligonucleotide antisense directed against insulin receptor substrate 1 gene expression to reduce corneal neovascularization. This report raises some interesting questions. Insulin receptor substrate 1 engagement by insulin is an essential step in mediating insulin-induced responses that include stimulation of mitosis and metabolism. Did the authors determine whether this treatment has any disruptive effects on corneal and/or conjunctival epithelial integrity and function? This could be clarified by measuring corneal and conjunctival lissamine green staining, tear flow, and other determinants of ocular surface discomfort. Applying this battery of tests rather than relying on only one of them to assess changes in ocular surface integrity and function would be meaningful; limiting the evaluation to a single test result can be inconclusive. The latter approach can be problematic, because it may lack sufficient sensitivity and specificity to determine if the effects of aganirsen are limited to inhibiting neovascularization.
Putative Neuroleptic Malignant Syndrome Associated With Sertraline Withdrawal

To the Editors: N euroleptic malignant syndrome (NMS) is a serious and potentially fatal complication of treatment with antipsychotic drugs, characterized by muscular rigidity, hyperthermia, autonomic dysfunction, and altered consciousness. Although, initially, only neuroleptics, which are predominantly dopamine receptor antagonists, were thought to induce NMS, subsequently, antidepressants, atypical antipsychotics, and other drugs have also been associated with NMS. Neuroleptic malignant syndrome may also occur after abrupt withdrawal of levodopa and other antiparkinsonian drugs. To the best of our knowledge, there are, as yet, no reports on NMS emerging upon discontinuation of sertraline, a selective serotonin reuptake inhibitor (SSRI), which is also a relatively potent dopamine reuptake blocker. In the following, we report a case of NMS in a patient under treatment with sertraline upon its abrupt discontinuation.
DERIVATIVES IN SOUTH AFRICA – AN EMPIRICAL INVESTIGATION

This paper, which is the second of a two-part series, presents the empirical findings of testing a number of variables influencing investors’ decisions to use derivatives in their portfolios. Five variables were deemed very important by a sample of 21 experts in the financial services industry in South Africa. These were: the level of information available (including the transparency of price determination); investor’s knowledge of different derivative instruments; investor’s level of risk tolerance; the level of liquidity in the market; and investor’s knowledge of and familiarity with financial markets. Education is required to change negative sentiments regarding derivatives and more regulation is called for, especially in over-the-counter markets.
A Case Study On Factors Influencing Credit Card Usage

Credit cards have become a necessity to the public and the number of credit cards approved has increased recently. Due to that factor, it had led to the increment of credit card debts. While some of the credit card holders used it wisely, most of them struggled to pay the minimum balance every month. Therefore, it is time to look into this matter. Thus, the objective of this study is to find the correlation between influencing factors and the credit card debts among KLM private hospital staff. The study used convenience sampling and the survey was conducted among 120 credit card holders in the KLM private hospital staff. It is found that only credit related knowledge is significant and has positive influence to the credit card debts. In conclusion, Malaysian government should tighten the guideline of approving credit card by a commercial bank. The aggressive promotion by commercial banks should be controlled and the continuous education on the impact of credit card debt to Malaysian should be done regularly. Commercial banks must play their role in advising the credit card holders on the advantages and the disadvantages of using the credit cards.
Using DEM to assess the influence of stress and fabric inhomogeneity and anisotropy on susceptibility to suffusion

Underfilled and gap-graded soils are known to be susceptible to suffusion; a form of internal instability in which the finer fraction of a soil is washed out from the coarser matrix under the action of seepage. This phenomenon poses a risk to embankment dams and flood embankments. The processes and mechanisms operate at the particle scale, and insight can be gained via the particulate discrete element method (DEM). Vir-tual samples can be created using DEM and simulation results can provide information on particle stresses, as well as quantitative information on the fabric of the particulate material. This is important as the amount of stress carried by the finer particles is thought to govern the susceptibility of a given material to suffusion. DEM modelling can also provide information on variation in properties within samples as well as the detailed data needed to quantify the material fabric. DEM models are, however, an idealization of reality and con-strained in particular by the number of particles used and sample preparation method. This study examines key issues relating to the development of virtual samples for use in DEM analysis and also examines the proportion of the applied stress that is carried by the finer particles.
