Laboratory attitudes and practices in the conservation of biological tissues for research purposes in Cote d'Ivoire
Background : Since 2009, Côte d'Ivoire has had a biobank, which now houses the ECOWAS regional biobank. This biobank intends to set up a biological tissue bank for research. In Côte d'Ivoire, several public and private structures handle biological tissues. However, we do not know which ones are involved in the conservation of biological tissues and their related procedures. To ensure optimal conservation of biological tissues at the biobank of Côte d'Ivoire, it is necessary to conduct a study on the state of the art of tissue preservation in Côte d'Ivoire. The objective of our work is to know the attitudes and practices of biological tissue preservation in Côte d'Ivoire.Methods : This is a descriptive study carried out in biological analysis laboratories in the south of the Ivory Coast.Results : A total of 66 laboratories agreed to answer the questionnaire that was proposed to them. Among them, only 21.21% kept biological tissues, of which 42.86% were human tissues, 35.71% animal tissues and 21.43% plant tissues. Human tissuesz were stored in formalin at room temperature for a period ranging from 2 weeks to 6 months. Animal biopsies and surgical specimens were stored in formalin and at -80°C for an indefinite period of time. Plant tissues were stored at room temperature and +4°C for an indefinite period of time.Conclusion : The conservation quality of biological tissues still needs to be improved
Avatars, disconnecting agents: exploring the nuances of the avatar effect in online discourse
A recurring theme in the study of unethical and harmful behavior is disconnection. And therefore perhaps it is no surprise that when individuals view themselves as a separate entity, they can loosen or even lose their moral compass. This phenomenon is known as the avatar effect. The experiment reported here explores the avatar effect in online communities. It explores whether participants adopt the suggested traits of a given entity when they communicate via that entity. The results revealed that participants' youtube comments were significantly influenced by their username and profile image, despite being asked to give their own opinion. The paper offers further insight into the growing field of disconnecting agents and compromised ethics
Psychological and sociological factors impacting on migrant worker contribution to, and adaptation of, workplace safety culture
This paper highlights potential health and safety issues which may emerge in workplaces engaging migrant workers, particularly as effected by social distancing during training prior to employment, such as experienced by international students. There are a number of factors that can contribute to the ways in which a migrant worker applies health and safety in their workplaces, including language and culture, that are commonly addressed through training, socialisation and workplace engagement. With these opportunities limited due to social distancing, migrant workers have less opportunity to contribute to and embrace organisations’ safety culture. This onus then falls onto employers to ensure that safe practices are learned, imbued and correctly and consistently applied with an objective of fostering a strong safety culture where employees go above and beyond what is expected in terms of safety performance that is mutually understood and shared
Panel data analysis of employment and unemployment in Sub-Saharan Africa and its impact on annual percentage change in GDP growth
ABSTRACTSub-Sahara Africa has over the years been exposed to diverse arguments and agitations about the provision of employment to alleviate poverty in the sub region with the aim of achieving full employment. Whereas some economists and bibliographers believe of the significant impact that employment and unemployment have on annual percentage change in GDP growth, some do not. The main objective of the study is to access the impact that employment and unemployment have on annual percentage change in GDP growth in Sub-Saharan African countries. World Development Indicator (WDI) data was collected from the World Bank from the year 2000 to 2014 for the purpose of the study. A sample of 12 sub-Saharan African countries were randomly selected using a random number generator and variables taken. Two statistical models were used; the Pooled Ordinary Least Square (OLS) regression model and the Least Square Dummy Variable (LSDV) regression model with fixed effect was used to empirically access impact that employment and unemployment have on annual percentage change in GDP growth. Both the Pooled Ordinary Least Square regression model and the Least Square Dummy Variable regression model tested to be statistically significant but LSDV regression model explained a greater percentage of the variability of the model than the Pooled OLS for employment on GDP growth rate. The pooled OLS regression model was not statistically significant at 5% level of significance in assessing the impact that unemployment has on annual percentage change in GDP growth. Further empirical analysis of the study also revealed a positive relationship between annual percentage change in GDP growth and employment for the female population (Empl15+Female), employment rate for the male population (Empl15+Male) and employment rate for the Total Youth population (Empl15-24 total). Also, an inverse relationship existed between unemployment male youth population (15-24years), and female youth population (15-24years) on annual percentage change in GDP growth. The study can be improved by considering other factors that impact GDP growth other than employment and unemployment.Keywords: Employment, Unemployment, GDP growth rate, Pooled OLS, LSD
Self-construal priming reconsidered: Comparing effects of two commonly used primes in the UK and China
Self-construal priming was devised to mimic the effects of chronic cross-cultural differences. Primes designed to activate independent/interdependent self-construals have been found to affect numerous culturally relevant outcomes. However, researchers have rarely checked precisely what these primes activated, nor tested their cross-cultural equivalence. We compared two common priming tasks, Similarities vs. Differences with Family and Friends (SDFF) and Sumerian Warrior Story (SWS), across seven dimensions of independence/interdependence among 118 British and 178 Chinese participants. The two tasks activated different combinations of self-construal dimensions. SWS showed a similar pattern of effects across cultures, whereas SDFF more strongly affected Chinese participants. Neither manipulation closely mimicked the pattern of pre-existing cross-cultural differences between samples. We propose researchers should develop more precisely targeted self-construal primes
The methodology and subject matter in sociology of the founding fathers of Ibn Khaldoun and Auguste Comte: A comparative study
AbstractThis study provides a discussion about the contributions and efforts made by Ibn Khaldoun and Auguste Comte to develop sociology in terms of subject matter and methodology. Since they are the founding fathers of this science, this paper shows their interpretation of the social phenomena. The study is also exposed to the reasons that led Ibn Khaldoun and Auguste Comte to study sociology. Accordingly, the research peculiarity required using historical, comparative, and critical approaches.The central problem of this study is how Ibn Khaldoun and Auguste Comte deal with the development of sociology and its independence from other sciences. The study results showed the accordance of both Ibn Khaldoun and Auguste Comte in terms of the methodology of sociology as being a positive approach consisting of observation and induction. Ibn Khaldoun's distinction, due to his five-century precedence, is vivid though. The results of the study also showed that Ibn Khaldoun and Auguste Comte differed greatly in terms of the divisions of sociology (subject matter of sociology): where Ibn Khaldoun divided the subject of sociology into multiple sections, each section includes a set of homogeneous social phenomena in peculiarity. Ibn Khaldoun studied the phenomenon by mingling the static aspect and dynamic one together, analyzing its parts, elements, and functions and at the same time studying its development and the laws to which it is subject to development. However, Auguste Comte has divided the social phenomenon into two main parts: Social dynamics and social statics
A Review of Literature in Applied Five Factor Model of Personality among Staff at Workplace
Staff feeling and performance at the workplace and obtaining a high level of outcomes drive from various factors; in truth, the human being is complicated and there are numerous internal and external factors that have an impact on it. Personality determined as one of these main internal factors that introduced individuals at their personal and social life; furthermore, recognizing its deep definition and effect on the approach and accomplishment of staff stays valuable and essential. Personality consists of five main factors: neuroticism, extraversion, openness, agreeableness, and conscientiousness that each person based on these factors illustrates dissimilar behavior and response. Additionally, the person introduced or well-known via these factors. Incidentally, the present literature review surveys five personality factors amongst staff in the context of the five-factor model and analyzes staff performance and behavior at the workplace. Overall, the study emphasized the role of managers, leaders, supervisors, etc. at the workplace to identify and evaluate staff personality, because by recognizing staff personality managers can offer a suitable solution to coping and solving any type of conflict or issue.
The morphological and molecular characterization of Trichoderma spp. in cocoa agroforestry systems
Species of the genus Trichoderma have been used as growth inhibitors and regulators of phytopathogens. The aim of this work was to study and molecularly characterize the species of the genus Trichoderma that can be found in the rhizosphere of cocoa agroforestry systems in the state of Tabasco, Mexico. Four composite samples were taken from each of three municipalities (Cardenas, Comacalco and Cunduacan). Thirty homogeneous sub-samples were taken (0-30 cm of depth) from each site (plantation) in a random zig-zag pattern across the middle part of the plantations, avoiding the edges. Thirteen strains of the Trichoderma genus were isolated and morphologically identified, while two species, T. harzianum and T. koningiopsi, were molecularly identified. Of the 13 strains, only five were amplified, and of these five, four corresponded to T. harzianum and one to T. koningiopsi
Analyzing the economic variables and their relationship to inflation in the US, China and Germany: Why empirical results demonstrate the inability to accurately assess economic policy through data
For the past 50 years, economists used the quantity theory of money to explain inflation. Monetarists, like Milton Friedman, view inflation as “everywhere a monetary phenomenon” and cite data comparing the quantity of money per unit of output (Real GDP) with CPI (inflation). Once scaled, the data appears strongly correlated. Critics state large action in the past decade by central banks did not lead to inflation. Recent research claims, “rapid money supply growth does not cause inflation...neither do rapid growth in government debt, declining interest rates, or rapid increases in a central bank’s balance sheet.” I test claims about the causes and predictability of inflation through a cross-country examination of different policies and their correlation with countries’ inflation rates. The study of inflation and its causes is important as the price mechanism is considered the mudsill of a functioning market, and countries aim to minimize large, unpredictable changes (hyperinflation, deflation). I examine empirical data from March 1959 - March 2020 in the United States through a multivariate linear regression model and then compare this with data from China 1996-2016 and Germany 1991-2020 as global references. I demonstrate the theoretical contradiction that, in the US, personal spending and high taxes correlate with inflation while government spending and monetary injections do not. I also demonstrate two key findings. First, interest rates appear to react to inflation rather than cause it. Second, there are no predictable causes of visible inflation in a global market. My results are inconclusive; yet the puzzling nature of their indications is evidence against broad monetary claims in general
The use of the legend of sleepy hollow in EFL classrooms
Considering the value of literary texts as authentic language materials to provide real uses of lexical and syntactic items and interesting subjects for students to connect better with the language. In addition, taking in account the characteristic of light horror presented by Irving in the story proves adaptable for different levels and ages, we should use this factor to attract the student for the subjects of our planning. As the use of literature in language lessons stimulates mostly the use of three skills: reading, writing and speaking. This short article collects activities prepared to help EFL students to advance in these areas, and, by the addition of the video as a resource, which presents a context of leisure and entertainment, and could modify student’s posture and expectations in relation to its use (MORÁN, 1995).
