Comunicación de la responsabilidad social empresarial de las empresas de América Latina en Facebook: estudio comparativo con las empresas globales

espanolEl nuevo contexto organizacional en America Latina cambio la manera en que las empresas se relacionan con sus publicos. La responsabilidad social empresarial (RSE) puede ayudar a las empresas latinoamericanas a lograr mayor integracion en el entorno social y fortalecer las relaciones con sus publicos. Las redes sociales, particularmente Facebook, pueden ser herramientas claves para la comunicacion de las actividades de RSE, ya que contribuyen positivamente a la reputacion corporativa. El objetivo de este estudio es analizar la comunicacion de la RSE de las principales empresas de America Latina en Facebook. La investigacion incluye un analisis comparativo con las principales empresas globales y revela que las empresas tratan los temas sociales con menos frecuencia que los temas economicos en Facebook. Las empresas usan Facebook como un canal de difusion mas que como un canal de comunicacion de su RSE, por lo que se hace necesario un enfoque mas interactivo y dialogico en esta red social. EnglishThe new Latin American organizational context changed the way companies relate to audiences. Corporate social responsibility (CSR) can help Latin American companies to better integrate into their social environment and strengthen relations with their audiences. Social media, particularly Facebook, can be key tools for disseminating CSR endeavors, as they positively contribute to corporate reputation. This study intends to analyze CSR communication on Facebook by major Latin American companies. The research includes a comparative analysis of these companies and reveals that they deal with social issues less often than economic issues on Facebook. Companies use Facebook as a broadcasting medium rather than as a communication channel for their CSR, so a more interactive and dialogic approach is needed for this social media website. portuguesO novo contexto organizacional na America Latina mudou a forma como as empresas se relacionam com seu publico-alvo.

Oral HPV prevalence in general healthy dental patients and patients with oral and oropharyngeal neoplasms in Bulgaria

The attention of oncologists and maxillo-facial specialists has been focused on the relation between HPVs and oral carcinogenesis. Oral HPV infection has been identified as an independent risk factor for oral squamous cell cancer. Over 150 subtypes of HPV have been identified; more than 40 types of HPVs infect the anogenital region and oral cavity. It has been predicted f this that tendency continue this virus will become more wide spread. By 2020, HPV associated tumors of the throat will surpass the incidence of cervical cancer as the leading HPV –induced neoplasm. It is highly recommended that each patient with a suspicious lesions in the oral cavity should be tested for HPV. We aimed to investigate the presence of HPV in of healthy individuals and in biopsy tissue of patients with oral and oropharyngeal neoplasms.
Effect of Seedling Age and Weed Management on Growth and Yield of Transplanted Rice (Sakha 106 cv).

: Two field experiments were conducted at the Experimental Farm of Sakha Agricultural Research Station, Kafrelsheikh, Egypt during 2016 and 2017 summer seasons to study the effect of seedling age and weed management on growth and yield of transplanted rice (Sakha 106 cv). A split plot experimental design arranged in randomized complete block with four replications was used in both seasons. Three seedling ages viz., 21, 28 and 35 days were allocated to the main plots, while five weed control treatments i.e., thiobencarb (50% EC) at 2.39 kg ai ha -1 , oxadiazon (25% EC) at 0.045 kg ai ha -1 , penoxsulam (24% SC) at 0.029 kg.ai ha -1 , hand weeding two times (20 and 40 DAT) and untreated (weedy check) were assigned to the sub-plots. The results showed transplanting rice seedlings at 21 days old recorded the lowest dry weight of Eclipta sp C. difformis E crus-galli and total weeds. Also, the increasing in rice dry weight, number of panicles m -2 , panicle weight, number of filled grains panicle -1 , 1000-grain weight and rice grain yield as compared to rest seedling ages (28 and 35 days). The application of penoxsulam at 0.029 kg ai ha -1 applied at 15 DAT achieved the lowest dry weight of weed species and total weeds as well as the highest rice yield as compared to weedy check. The interaction between seedling ages and weed control treatments had significant effect on dry weights of weed species, total weeds dry, rice yield and its components. Where, transplanting rice seedlings treatment at 21 days old treated with herbicide of penoxsulam at 0.029 kg ai ha -1 at 15 DAT are the best among the studied treatments to achieve the best weed control and the highest rice dry mater, grain yield and its components for Sakha 106 cv. under this study conditions.
The material and mental effects of animal disappearance on indigenous hunter-gatherers, past and present

ABSTRACT For indigenous hunter-gatherers, dependent for their subsistence and well-being on prey animals, animal extinction had significant and multifaceted effects, only some of which are reflected in the archaeological record. Contemporary hunter-gatherers often view animals as equal partners in a shared habitat, where these animals are simultaneously hunted and revered. We posit that this same duality existed among past hunter-gatherer groups. The disappearance of a species that supported human existence for millennia triggered not only technological and social changes but also had profound emotional and psychological effects. We present several selected case studies that reflect the complex dual relationship between indigenous hunter-gatherers and their prey under different environmental conditions. We focus on the material and mental effects of animal population decline over diverse cultures, geographies, and time scales. Our study sheds light on the vital role of specific animal taxa in human biological and cultural evolution. It also deepens our understanding of how indigenous hunter-gatherer societies expressed their awareness of coexistence with other species. In the age of the Sixth Extinction, this study might be more relevant than ever not only for reconstructing the life ways of indigenous hunter-gatherers but for all human and nonhuman species populating the planet.
Electrospinning a Dye-Sensitized Solar Cell

Dye-sensitized solar cells (DSSCs) offer new possibilities to harvest solar energy by using non-toxic inexpensive materials. Since they can generally be produced on flexible substrates, several research groups investigated possibilities to integrate DSSCs in textile fabrics, either by coating full fabrics with the DSSC layer structure or by producing fiber-shaped DSSCs which were afterwards integrated into a textile fabric. Here we show a new approach, electrospinning all solid layers of the DSSC. We report on electrospinning the counter electrode with a graphite catalyst followed by a thin nonconductive barrier layer and preparing the front electrode by electrospinning semiconducting TiO2 from a polymer solution dyed with natural dyes. Both electrodes were coated with a conductive polymer before the system was finally filled with a fluid electrolyte. While the efficiency is lower than for glass-based cells, possible problems such as short-circuits—which often occur in fiber-based DSSCs—did not occur in this proof-of-concept. Since graphite particles did not fully cover the counter electrode in this first study, and the typical bathochromic shift indicating adsorption of dye molecules on the TiO2 layer was not observed, several ways are open to increase the efficiency in forthcoming studies.
Séméiologie et vécu des hypoglycémies chez 100 diabétiques traités par l'insuline

The aim of this study was to discover the frequency and the symptoms of hypoglycaemic reaction and coma. One hundred type I diabetic patients answered an oral questionnaire and explained how they were awaken from their hypoglycaemicoma. The frequency of hypoglycaemic reaction was from one a day to one a year. 41 patients had nocturnal hypoglycaemic reactions. Our patients described 27 different symptoms of oncoming attack; however, not all of these symptoms was experienced by any one of the patients. Treatment of hypoglycaemic reaction was administered correctly but at the precise moment of the interview, 13% of patients had no carbohydrates with them. 42 patients had had hypoglycaemic reaction but no coma. Shared between 48 patients were 578 insulin years and 148 comas. Treatment of hypoglycaemic coma was variable: 20 patients remained at home receiving appropriate treatment; 33 were always hospitalised on attack and 20 were still comatous on each admission. The explanation of hypoglycaemic attack was variable; an emotional factor was given by 19% of patients. Both type I diabetic patients and their immediate entourage should be made aware of all the symptoms of oncoming attack and of the treatment of hypoglycaemic coma. Systematic glycemic auto control should testify to the existence of genuine hypoglycaemic reaction and perhaps diminish its supposed frequency.
Does constituency focus improve attitudes to MPs? A test for the UK

ABSTRACT A substantial literature demonstrates that in advanced democracies the public generally prefer for MPs to be focused on their constituencies. However, prior research fails to prove that the general public is aware when MPs are doing so, and whether their views of the MP change correspondingly. I test this using a high-quality proxy for constituency focus – talking about the constituency in the House of Commons – linking this to British Election Study survey data on perceived constituency focus and trust. I show that ‘real' constituency focus strongly predicts perceived constituency focus and also predicts trust. As expected, these effects exist only for constituents who know (recall) their MP's name. While previous studies argue that the public want ‘workhorses' who offer ‘value for money’ by speaking in Parliament, I instead suggest that the focus, not the volume, of activity can be a more productive route for MPs to develop trust.
Road traffic injuries in Namibia. A mixed methods study to analyse the trends in mortality and morbidity due to road crashes, and to investigate the long-term effects of road injuries

Background: Road traffic injuries (RTIs) are a major problem worldwide. In this mixedmethods thesis I investigated the trend of RTIs in Namibia, which is one of the worst affected countries globally. I also investigated the long-term impacts of RTIs and the role of a fuel levy fund - The Motor Vehicle Accident Fund (MVAF) - in enhancing the availability of rehabilitation and counselling services to RTI survivors in Namibia. Methods: Using quantitative methods, I conducted analysis of data sets on RTIs from 2012 to 2014. Descriptive analysis was used to characterise crashes, injuries and deaths, and people affected. Further to this, I conducted multinomial logistic regression in order to investigate the likelihood of having been injured or killed. Using qualitative methods, I conducted semi-structured interviews with RTI survivors in Namibia, and healthcare workers involved in caring for them, in order to investigate the long-term impacts of RTIs and the availability of rehabilitation and counselling services to road injury survivors in Namibia and the role played by the MVAF. Results: The quantitative analysis showed over 2012-2014, the rates of injury and death had risen by 3.9% and 1.1%. Logistic regression identified the road user group had the greatest influence on the risk of being injured and killed. The method of transportation to hospital had the greatest influence on the risk of dying among those admitted to hospital. The qualitative analysis showed that RTIs are associated with long-term physical and mental health sequalae, financial hardships, and various social problems. The analysis also showed the MVAF is effectively helping to enhance access to rehabilitation and other health services for RTI survivors. Conclusion: The present study adds to the knowledge of the long-term impact of RTIs and presents new information from Namibia, where no previous studies of this kind have been done.

Initial coin offerings

This paper presents a first-ever empirical examination of the market for initial coin offerings (ICOs). ICOs are smart contracts based on blockchain technology that are designed for entrepreneurs to raise external finance by issuing tokens without an intermediary. Unlike existing mechanisms for early-stage finance, tokens provide investors with an anytime-exit opportunity thanks to liquid trading platforms. The marketability of tokens offers novel insights into entrepreneurial finance, which I explore in this paper. First, I document that the average ICO firm underprices by 8.2%, which means the average entrepreneur leaves $1.1 million “on the table. ” However, about 40% of all ICOs destroy investor value on the first day of trading. Second, I explore the determinants of market outcomes and find that management quality and the ICO profile are positively correlated with the funding amount and returns, whereas highly visionary projects have a negative effect. Among the 21% of all tokens that get delisted, highly visionary projects are more likely to fail, which investors anticipate. Third, I explore the sensitivity of the ICO market to adverse industry events such as China’s ban of ICOs, the hack of leading ledgers, and the marketing ban on FaceBook. I find that the ICO market is highly susceptible to such environmental shocks, resulting in substantial welfare losses for investors. JEL classification: G24, G32, K22, L26.
Onward and Upward? An Empirical Investigation of Gender and Promotions in Information Technology Services

Is there a gender bias in promotions at information technology (IT) companies? Do women get an equal lift in their promotion prospects from performance improvements, work experience, and training as men? These are pertinent and important questions affecting today’s IT human capital. We analyze data from a leading IT services firm using robust econometric techniques to suggest that, contrary to expectations, women are more likely to be promoted. Although we do not find any evidence of overt discrimination, our findings, however, are far more nuanced and imply that there may be covert discrimination against women in IT when it comes to promotions: compared with men, women realize less benefit from performance gains than men, less benefit from tenure within the focal firm, but more benefit from training. Although our analysis is limited to the lower rungs of the organizational hierarchy, we propose several actionable managerial and policy insights that can potentially make IT firms more inclusive and attractive to women: more parity in the effect of performance improvements and work experience on promotions and using training as a signaling mechanism that can identify and encourage stellar women as they navigate the promotional ladder in IT firms.
The impact of the level of customer satisfaction on the quality of e-commerce services

The purpose of this paper is to present the results of surveys conducted in the field of level of e-commerce services quality. The criteria of quality of e-commerce services were identified. On this basis the hierarchy of importance of the adopted criteria for e-commerce service quality were proposed. ,The level of customer satisfaction was measured using the Servqual method. In order to compare two groups: the quality of e-commerce services before purchase and the quality of e-commerce services after the purchase, a student’s t-test was used. To check if the relations between variables are sufficient to carry out the factor analysis (sampling adequacy), the Keizer–Meyer–Olkin test was used. The scope of the research included 23 selected criteria of customers satisfaction. ,A comparison of the Servqual weighted and unweighted results shows that customers valued the guarantee/safety dimension the most. It can therefore be expected that customers perceive e-commerce services with increasing trust and consider them increasingly reliable which is also confirmed by the growing tendencies in the forecasts of e-commerce services in Poland. ,Research allows to know the opinion and expectations related to the quality of services provided in the analysed area and to develop the strategy of company. The most important indicator of the quality of e-commerce services remains reliability (weighting = 0.34). However, the noticeable difference in opinions concerns the tangible elements index compared to the results of the Berry and Parasuraman team and amounted to 0.20.
ISOLATION OF Brucella abortus FROM ABORTED LAMBS IN THE GOVERNORATE OF SULAIMANIA /SAID-SADIC DISTRICT

Brucella abortus was isolated and identified from aborted lambs in the Governorate of Sulaimani /Said-Sadic district. The blood agar, candle jar and 37°C incubator were successfully used. Microbiological and biochemical tests were used for identification of the isolates. Although previous incidence of brucellosis prevalence has been reported serologically in the area but the present study could represent the first attempt for B. abortus isolation, with local available facilities in the Governorate of Sulaimani.
Induction Of Chronic Stress Reveals An Interplay Of Stress Granules And TDP-43 Pathological Aggregates In Human ALS Fibroblasts And iPSC-Neurons

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are fatal neurodegenerative diseases characterized by the presence of neuropathological aggregates of phosphorylated TDP-43 (P-TDP-43). The RNA-binding protein TDP-43 is also a component of stress granules (SG), cytoplasmic foci forming to arrest translation under sub-lethal stress conditions. Although commonly considered as distinct structures, a link between SG and pathological TDP-43 inclusions may occur despite evidence that TDP-43 pathology directly arises from SG is still under debate. Primary fibroblasts and iPSC-derived neurons (iPSC-N) from ALS patients carrying mutations in TARDBP (n=3) and C9ORF72 (n=3) genes and from healthy controls (n=3) were exposed to oxidative stress by sodium arsenite. SG formation and cell response to stress was evaluated and quantified by immunofluorescence and electron microscopy analyses. We found that, not only an acute, but also a chronic oxidative insult, better mimicking a persistent condition of stress as in neurodegeneration, is able to induce SG formation in primary fibroblasts and iPSC-N. Importantly, only upon chronic stress, we observed TDP-43 recruitment into SG and the formation of distinct P-TDP-43 aggregates, very similar to the abnormal inclusions observed in ALS/FTD autoptic brains. Moreover, in fibroblasts, cell response to stress was different in control compared with mutant ALS cells, probably due to their different vulnerability. A quantitative analysis revealed also differences in terms of number of SG-forming cells and SG size, suggesting a different composition of foci in acute and chronic stress. In condition of prolonged stress, SG and P-TDP-43 aggregate formation was concomitant with p62 increase and autophagy dysregulation in both ALS fibroblasts and iPSC-N, as confirmed by immunofluorescence and ultrastructural analyses. We found that exposure to a chronic oxidative insult promotes the formation of both SG and P-TDP-43 aggregates in patient-derived cells, reinforcing the idea that SG fail to properly disassemble, interfering with the protein quality control system. Moreover, we obtained a disease cell model recapitulating ALS/FTD P-TDP-43 aggregates, which represents an invaluable bioassay to study TDP-43 pathology and develop therapeutic strategies aimed at disaggregating or preventing the formation of pathological inclusions.
Risk factors for severe acute malnutrition in under-five children attending nutritional rehabilitation centre of tertiary teaching hospital in Karnataka: a case control study

Nutrition is essential for human development. Malnutrition not only enhances morbidity and mortality amongst children, it also leads to reduced work capacity and poor productivity when these children grow up as adults, hampering the development of a country. SAM was defined as per WHO and same norm is used mostly everywhere. India is being recognized as having, perhaps, the worst malnutrition problem in the world which is much more than Sub-Saharan Africa or Latin America. The findings of the National Family Health Survey (NFHS-4) reveal.
