Amplifying \u27whispered interventions\u27 into loud and forceful cries

An equitable educational environment includes the voices of the individuals and the power of their stories. For marginalized people, particularly women of color, surviving school means existing in oppressive environments which require the stealing of knowledge while struggling to obtain an education (Collins, 2002). It is imperative that institutions acknowledge the specific complexities women of color face in the academy (Crenshaw, 2017). This study is designed to make meaning of the journey of Black women doctoral students using counterstories and composite stories to capture and learn from their lived experiences. Through the (re)covery and (re)telling of the stories of Black women, the research amplifies knowledge production by highlighting the perseverance, adaption, and resilience of these scholars. This work is revolutionary and the act of doing such work is subversive, difficult, and dangerous (Dillard, 2012). To subscribe to this change; institutions should work toward the inclusion of new voices, ideas, paradigms, and frameworks (Nieto, 2000). As the work of social justice and equity is (re)framed, institutions and dominant cultures need to remain clear that cultural relevance and the treatment of marginalized populations is at the center of these critical conversations

5.5 Pesticide and Metabolites Residues in Honeybees: A 2014-2017 Greek Compendium

In the period between 2014 mid-2017, more than 200 samples of honeybees were sent by authorities and individuals in Benaki Phytopathological Institute after incidents of unexpected deaths of bees in various parts of Greece. The samples were analyzed for pesticides and breakdown products, by two multi-residue methods based on an expanded HPLC-ESI-MS/MS and a newly developed GC-MS/MS method. Sample preparation was optimized and based on modified QuEChERS using for clean-up C18 and PSA. Until mid-2017, 293 detections were registered in a total of 205 honeybee samples, resulting in a 76% percent of positive samples, to at least one active substance. Concentrations’ range varied from 1 to 160000 ng/g bee body weight . In some cases, these levels surpassed LD50 values indicating intoxication events. Predominant substances were clothianidin, coumaphos, imidacloprid, acetamiprid and dimethoate. In less extent, other acaricides such as amitraz (mostly its breakdown products DMF, DMPF), tau-fluvalinate and certain pyrethroids exemplified by cyhalothrin, cypermethrin and deltamethrin were also recorded. In several samples, more than one active substance was detected.Overall, this work aspires to provide valuable insight to pesticides and metabolites occurrence in honeybees in Greece between 2014-2017 and in parallel assist research community and apiculturists in this pivotal Mediterranean region that bee health and pollination services have prolific importance.In the period between 2014 mid-2017, more than 200 samples of honeybees were sent by authorities and individuals in Benaki Phytopathological Institute after incidents of unexpected deaths of bees in various parts of Greece.

Student perceptions of factors influencing throughput in an accounting programme in Botswana

Thesis (MPhil)--Stellenbosch University, 2016ENGLISH ABSTRACT : The aim of this study was to investigate students’ throughput in an Accounting programme at Botho University, a Botswana university. There is a high demand for qualified Chartered Accountants in Botswana, and the issues of dropout, reduced retention and attrition of accounting students especially in the Department of the Association of Accounting Technicians (AAT) have contributed to this national shortage. The study used an interactive qualitative analysis (IQA) methodology and was situated within the interpretivist research paradigm. The research focused on only one constituency, a selected group of AAT students who failed to progress from semester 1 to semester 2. The study involved research activities which included conducting focus group and individual interviews with participants gaining an understanding of the identified problem through the analysis and interpretation of data collected. The researcher compared the system influence diagrams (SIDs) for focus group and individual interviews, and the research revealed that low student throughput was as a result of inconsistencies in institutional policies, socio-economic problems, lack of students’ commitment and poor interaction between lecturers and students. The findings in this study further revealed that there were some discrepancies between Botho University’s assessment policy and how the AAT diploma was offered in the United Kingdom. Botho University finds itself in the dilemma of handling contradictory competing goals between the financier (Department of Tertiary Education and Financing) and the franchiser (Association of Accounting Technicians). The study reported in this thesis indicated that it may take time for Botho University to amend its institutional policy due to complex compliance matters. However, the following are the suggested implications to be considered in order to address low student throughput at Botho University, based on the participants’ perceptions: an improvement in the provision of library space, recruitment of specialised academic personnel (subject matter experts), and flexible timetabling. Finally, considering the challenges revealed in this study, implementation of strategies towards improving the situation is encouraged in order to address the low student throughput at Botho University.AFRIKAANSE OPSOMMING : Geen Afrikaanse opsomming geskikbaar nie.Master

Headspace Solid Phase Micro Extraction Gas Chromatographic Determination of Fenthion in Human Serum

A simple and effective analytical procedure was developed for the determination of fenthion residues in human serum samples. The sample treatment was performed using the headspace solid-phase micro extraction with polyacrylate fiber, which has the advantage to require low amount of serum (1 mL) without tedious pre-treatment. The quantification of fenthion was carried out by gas chromatography-mass spectrometry and the recoveries ranged from 79 to 104% at two spiking levels for 6 replicates. Detection and quantification limits were calculated as 1.51 and 4.54 ng/mL of serum respectively. Two fenthion metabolites fenoxon and fenthion–sulfoxide were also identified

Predicting students' intention to continue online learning post COVID-19 pandemic: extension of the unified theory of acceptance and usage of technology

Purpose The purpose of this study is to predict the intention to continue online learning post the coronavirus disease 2019 (COVID-19) pandemic among students in the two largest universities of higher learning in Botswana. Furthermore, the purposes of this study are to elucidate the nexus between performance expectancy and continuance intention to establish the effects of efforts expectancy on continuance intention to investigate the relationship between social influence and continuance intention to determine the relationship between facilitating conditions and continuance intention and to examine the relationship between satisfaction and continuance intention using the extended unified theory of acceptance and usage technology (UTAUT) model postulated by Venkatesh et al. (2003). Design/methodology/approach The study is based on the descriptive research design, using a structured questionnaire to collect quantitative data from 509 undergraduate and postgraduate students at Botswana's two major Universities using convenience sampling strategy. An online survey was used to gather primary data due to the COVID-19 pandemic. The study employed correlation and regression analysis in testing the five hypothesized relationships. Findings Using the extended theory of UTAUT as a theoretical lens, the study found that: performance expectancy, social influence and satisfaction predict continuance intention of online learning services. These factors have shown to be good predictors of intention in previous research. Expectancy effort had no influence on intention. Research limitations/implications The current study covered on only university students from two tertiary institutions; therefore, results cannot safely be generalized to the student population in the country. Therefore, future research should consider enlisting more universities to be more representative, focusing on lecturers, which is an important group in fostering online teaching that could have a spill-over effect on the students' continued online learning. Practical implications Implications for online technology selection: These findings suggest that although most universities temporarily adopted online teaching as an emergency solution, students appear to have felt that the outcomes delivered by the system improved their performance. This implies that academic institutions need to consider adjusting the curriculum to promote online learning in the future, whether there is pandemic or no pandemic. Implications for teaching and learning: First, the concept of social influence suggests that lecturers can make use of online chat discussion boards and rooms to foster student collaboration and a sense of community. Second, and finally online service providers should foster a close relationship with students to understand their expectations and extend the performance of their applications to satisfy their users. Originality/value This study contributes to literature on online learning during the COVID-19 pandemic period by including satisfaction and continuance intention to the original UTAUT model thus extending the practical value of the model. This study extends knowledge on the factors that determine continuance intention by incorporating satisfaction in addition to the four factors of the traditional UTAUT. The study provides evidence for the predominance of satisfaction over the four traditional factors in predicting intention to continue online learning among students
