Bandits in the lab

We experimentally implement a dynamic public‐good problem, where the public good in question is the dynamically evolving information about agents' common state of the world. Subjects' behavior is consistent with free‐riding because of strategic concerns. We also find that subjects adopt more complex behaviors than predicted by the welfare‐optimal equilibrium, such as noncut‐off behavior, lonely pioneers, and frequent switches of action.
How Does Financial Sector Reacts After Special Events? An Event Study Analysis of Tunisia after the Revolution of 2011.

Using an event study analysis, we aim to investigate the impact of political, economic, social and terrorism events, on the Tunisian financial sector, over the period of the Tunisian Revolution; from (12)2010 to (04)2014. Based on a daily data analysis using three selected variables ; Sectoral index of performance of Tunisian banks ,Index of Tunisian stock market and the exchange rate Euro/ Dinar, the EGARCH model results have highlighted that general events decrease the return of our variables, and increase their volatility. More, results have shown that stock market is very sensitive to political and terrorism events, bad economic events increase the volatility of the exchange rate, and decrease the performance of banking sector. Political events remain the more important component, they affect negatively all the endogenous variables; coefficients in the mean equation show an important decline in term of the return of banking sector ,the stock market and the exchange rate.
Effect of Different Chemical Treatments on the Settleability of Palm Oil Mill Effluent

The effect of alum and ferric chloride on the settleability of suspended solids in raw palm oil mill effluent (POME) was compared with that of natural zeolite and calcium carbonate. This work forms part of our overall research on minimal discharge technology in the overall management of POME. The results showed that all the flocculants could effectively reduce more than 80% of the suspended solids but only 40-50% of the COD. The settled volume after 3-7 hours was generally xoithin 35-50% of the original mixture. The best settleability in increasing order were at 3 g/L ferric chloride, 11 g/L alum, 10 g/L zeolite and 20 g/L calcium carbonate. The fastest settling rate was obtained with 20 g/L calcium carbonate, where settling was almost completed within 2 hours as compared to more than 20 hours for raw POME. The dosage of zeolite was comparable to the traditional coagulants. As for calcium carbonate, although the dosage was higher, subsequent disposal or utilisation of the metal-free sludge solids fits well with our minimal discharge system for POME.
PKCδ and cofilin activation affects peripheral actin reorganization and cell-cell contact in cells expressing integrin α5 but not its tailless mutant

Integrin-mediated cell adhesion transduces signaling activities for actin reorganization, which is crucially involved in cellular function and architectural integrity. In this study, we explored the possibility of whether cell-cell contacts might be regulated via integrin-α5β1-mediated actin reorganization. Ectopic expression of integrin α5 in integrin-α5-null intestinal epithelial cells resulted in facilitated retraction, cell-cell contact loss, and wound healing depending on Src and PI3K (phosphoinositide 3-kinase) activities by a reagent that affects actin organization. However, cytoplasmic tailless integrin α5 (hereafter referred to as α5/1) expression caused no such effects but rather sustained peripheral actin fibers, regardless of Src and PI3K signaling activities. Furthermore, integrin α5 engagement with fibronectin phosphorylated Ser643 of PKCδ, upstream of FAK and Src and at a transmodulatory loop with PI3K/Akt. Pharmacological PKCδ inactivation, dominant-negative PKCδ adenovirus or inactive cofilin phosphatase (SSH1L mutant) retrovirus infection of α5-expressing cells sustained peripheral actin organization and blocked the actin reorganizing-mediated loss of cell-cell contacts. Meanwhile, wild-type PKCδ expression sensitized α5/1-expressing cells to the actin disruptor to induce cell scattering. Altogether, these observations indicate that integrin α5, but not α5/1, mediates PKCδ phosphorylation and cofilin dephosphorylation, which in turn modulate peripheral actin organization presumably leading to an efficient regulation of cell-cell contact and migration.

Work-related musculoskeletal disorders among health care professionals

Musculoskeletal disorders (MSDs) represent a significant occupational problem among health care professionals; however, data on prevalence of work-related musculoskeletal disorders (WMSDs) are limited in our country for referencing. A descriptive cross sectional study was conducted during January to December 2016 among 160 health care professionals (doctors, nurses) working in a tertiary care hospital in Dhaka city. The aim of the study was to determine the prevalence, distribution and to find out the multiple risk factors that contribute to the development of WMSDs among the sample population. Data were collected with semi structured questionnaire based on a validated research instrument Standardized Nordic Questionnaire (SNQ) which records the prevalence of MSDs in terms of musculoskeletal symptoms (ache, pain, discomfort) in the preceding 12 months. The statistical analysis was done by using the SPSS software 21 version. The study result revealed that out of 160 (100.0%) health care professionals 109 (68.1%) had musculoskeletal pain or discomfort in the last 12 months and 51 (31.9%) had not, and it was also found that 57 (61.3%) doctors and 52 (77.6%) nurses had musculoskeletal pain or discomfort in the last 12 months and the prevalence of work-related musculoskeletal disorders in different body region in the last 12 months, where more than 1 site involvement 46 (42.2%) followed by neck 19 (17.4%), shoulder 15 (13.8%), lower back 13 (11.9%), hips 8 (7.3%), hand/fingers 5 (4.6%). About the self reported risk factors among the health care professionals for WMSDs were found working the same position for long periods 48 (29.8%),followed by treating excessive number of patients in a day 47 (29.1%), inadequate training on injury prevention 25 (15.9%), working awkward or cramped position18(11.6%). There were no statistically significant association found in age and years of experience of the health care professionals with the WMSDs (p value .281, .083 respectively), but significant association found in sex and occupation of the health care professionals with WMSDs (p value .045, .031 respectively). As because a high proportion of health care professionals had WMSDs and they are on the risk for development of WMSDs, it can be recommended that education programmes on prevention and coping strategies for musculoskeletal disorders be made mandatory for health care professionals in order to reduce the rate of WMSDs among them and to promote efficiency in patient care.

IMMEDIATE REACTIONS TO MONOCLONAL ANTIBODIES IN CLINICAL HEMATOLOGY

Monoclonal antibodies (MoAbs) have been widely used in clinical hematology. As foreign macro-molecules, they can cause infusional reactions during the administration or within 24 hours after the infusion, which encompass a spectrum of mechanisms. Although most of these reactions are non-allergic, are often indistinguishable from true allergic reactions mediated by IgE immunoglobulins. The diagnosis is often challenging and relies mainly on clinical criteria. They occur during the first doses, soon after the initiation of treatment. The symptoms are usually well controlled by the immediate drug discontinuation or reduction of the infusion rate. The management remains largely supportive, consisting of oxygen, intravenous fluids, bronchodilators, antihistamines and steroids. Most of MoAb protocols recommend premedication with steroids and antihistamines and gradually escalating infusion rates. Increased medical and nursing vigilance is required and resuscitative equipment should always be readily available. These events affect patients' quality of life, leading to treatment delay or discontinuation and series of tests. The decision to rechallenge the treatment depends on severity grading, clinical parameters and treatment goals. This article provides an update of MoAbs used in clinical hematology. It summarizes the pathophysiology, the diagnostic approach, the preventive measures and treatment of MoAb-related reactions.

Iranian nurse attitudes towards the presence of family members during CPR

Aim: The presence of family members at the time of cardiopulmonary resuscitation (CPR) is essential in family-centered care. Since nurses have an important role in facilitating the attendance of patients' family members in this regard, the present study was conducted to examine nurse attitudes towards the family's presence during CPR. Methods: This study was conducted across three teaching hospitals in Kerman province located in South East of Iran. Using convenience sampling, all registered nurses were invited to participate in the study. Data were collected between January and March 2014 using the attitude questionnaire on family presence during resuscitation. Results: Of 303 nurses, 92.5% were women. The mean attitude score of nurses was 50.99 ±7.12. The main perceived barriers to family presence during resuscitation by Iranian nurses were increased stress and anxiety among CPR team members, traumatic experience for the family members, difficulty around stopping CPR in futile situations owing to family .
Management of black scurf (Rhizoctonia solani) and common scab (Streptomyces scabies) of potato through eco-friendly components

Black scurf ( Rhizoctonia solani) and common scab ( Streptomyces scabies ) diseases of potato are becoming prominent in many potato growing districts of Gujarat state resulting in economic losses, since a decade. An experiment was conducted to find out more economical and eco-friendly management approaches, taking cv. Kufri Badshah with thirteen treatments involving bioagents ( Trichoderma viride , T.harzianum and Bacillus subtilis strain B5), botanicals [Neem bann, onion ( Allium cepa L.) bulb extract and garlic ( Allium sativum L.) clove extract], organic amendment (farm yard manure) and boric acid applied individually or in combination. Seed tuber treatment (spray) with 2 per cent boric acid before storage followed by T. viride @ 8g/kg tuber treatment at planting registered the minimum black scurf incidence (6.42%) and index (0.17). Disease incidence was reduced by 81.22 % and severity index by 90.17 %. In case of common scab, tuber treatment with 3 per cent boric acid followed by B. subtilis tuber treatment @ 2.5g/kg recorded the lowest disease incidence (31.62%) and index (1.76). These treatments can provide an effective, economical and eco-friendly management of potato tuber diseases.
Experimental Study on G-Band Oversized Backward Wave Oscillator Driven by Weakly Relativistic Electron Beam

We studied a G-band oversized backward wave oscillator (BWO) driven by a weakly relativistic electron beam of less than 100 kV. Rectangular corrugations are used as slow-wave structures having surface waves with upper cutoff frequencies above 150 GHz (G-band). We examine how dispersion characteristics of surface waves are affected by accuracy in machining the corrugation amplitude, width, and period length. Of these, accuracy in the amplitude has the largest effect. Uniformly distributed annular electron beams are generated by a disk-type cold cathode and injected into the G-band BWO. G-band BWO operations in 137 - 173 GHz and above 173 GHz are achieved by changing the corrugation amplitude. The radiation patterns are fairly broad, and the estimated radiation power is at kW level.
Etiology and pathogenesis of Parkinson’s disease: role of mitochondrial pathology

Thus, any impairment in mitochondrial function results in neuronal damage and degeneration. Some particular neuronal populations are more susceptible to mitochondrial damage, as it has been recently proposed for the ventral midbrain dopaminergic neurons, the degeneration of which represents a clinical sign of Parkinson’s disease. Different cellular pathways are involved in the pathogenesis of this neurodegenerative disease, but intriguingly both sporadic and familial forms share common features that essentially recapitulate mitochondrial dysfunction. Mitochondrial biogenesis, bioenergetics, mitochondria dynamics, and quality-control process are the main affected pathways. General consensus agrees on the possibility that deficiency in these processes may represent the cause rather than the consequence of neurodegeneration. In this review, we will discuss these aspects and the substantial achievements that have been reached in recent years in identifying specific defects in precise biological processes, eg, mitochondrial quality control. The development of cell and animal genetic models has been an important tool to dissect numerous molecular details; for this reason, we will mainly refer to experiments performed on them.
The Effects of Fenthion on Lipid Peroxidation and Some Liver Enzymes: The Possible Protective Role of Vitamins E and C

The effects of fenthion on the serum activities of cholinesterase (ChE), enzymes concerning liver damage and lipid peroxidation (LPO), and the ameliorating effects of a combination of vitamins E and C against fenthion toxicity were investigated. The results of the in vivo experiment showed that fenthion caused a significant increase in LPO and the activities of aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT) and lactate dehydrogenase (LDH), and a significant decrease in the activities of ChE and alanine aminotransferase (ALT). In addition, treatment with a combination of vitamins E and C led to a significant decrease in LPO and AST activity. In the in vitro experiment, the activity of ChE and ALT were inhibited by fenthion. From these results, it can be concluded that fenthion caused liver damage, and LPO may be one of the molecular mechanisms involved in fenthion-induced toxicity. Vitamins E and C can reduce LPO caused by fenthion.
Understanding intention to use mobile learning: a perspective of the extended unified theory of acceptance and use of technology

The objective of this research paper is to gain a better understanding of the intention of students to take up mobile learning (m-learning) through an examination made on the underlying basis of the unified theory of acceptance and use of technology (UTAUT). There are a number of factors influencing the acceptance of m-learning, such as: technology factors (including effort expectancy and performance expectancy); implementation environment factors (facilitating conditions and social influence); and individual factors (self-regulation and self-efficacy). Ultimately, the findings of the research could enrich the student experience by giving schools a tool to better understand those factors impacting on the students’ ability to effectively utilize m-learning; thereby allowing schools to adapt their programs to enhance learning by way of the usage of m-learning. From the review of the literature and subsequent to the factors identified as mentioned above, a research model has been proposed. The model has the ability to enhance the current level of understanding as to the motivating factors influencing students’ motivation to utilize m-learning. This enhanced level of understanding can assist efforts to encourage and provide support for m-learning.
The Afterlife of Painting

i This thesis situates my painting practice within the broad context of developments arising from the so-called ‘death of painting’ and its aftermath. My claim is that those developments involved a change in the ontology or the nature of painting, so that it is no longer medium-specific but post-conceptual in its operations. Hence the title: The Afterlife of Painting. After an Introduction on the formulation of the research topic and its relation to my art practice, chapter one examines the arguments proposed for the death of painting. The principal finding is that the putative death was largely a discursive event centred on the New York art scene in the 1980s rather than an enduring historical reality for Western culture. Nonetheless, painting did undergo significant change from the 1960s, experimenting with new paradigms of production within an art world increasingly dominated by conceptual forms of art. Chapter two divides into three parts, each dealing with an aspect of my painting practice. Chapter 2.1: Methodology explores the question of contemporary painting when practised in the name of research, or as research, within the University context. Chapter 2.2: Methods focuses on my studio methods and their elaboration through a reflective process informed by the archive of past painting. Chapter 2.3: Theory then provides an account of ideas that have influenced my understanding of the production and reception of art, particularly the philosophies of Alain Badiou and Gilles Deleuze (with Felix Guattari). Chapter three uses Peter Osborne’s six-point definition of the conditions of postconceptual art to argue for a form of post-conceptual painting. I contend that Osborne gives insufficient weight to the aesthetic in art today, and I draw upon the work of J.M. Bernstein to discuss painting’s role in reclaiming our capacity for sensuous embodied experience. On the basis of these arguments, I define my own work as participating in the ontological change to post-conceptual painting. The Conclusion provides further reflection on the idea of an afterlife of painting, including painting’s temporal dimension and the recent rapprochement between aesthetics and ethics.
