The Adoption of E-learning by Students in Zimbabwean Universities in the Wake of COVID-19

COVID-19 effects have been felt in the education sector worldwide where schools, colleges, and universities were closed as a way to reduce the spread of the deadly pandemic and loss of lives. The Ministry of Higher and Tertiary Education. advocate that no child should be left behind during the COVID-19 era, therefore gave a directive for universities to use other alternative means of teaching and learning to continuously provide teaching and learning to students during the series of lockdown. An efficient eLearning system in universities is very important as an alternative to faceto-face teaching and learning in this COVID-19 era to have continuity in teaching and learning during the induced lockdowns. Success in online learning can be achieved by understanding the level of readiness of online learning environments. The main objective of the study was to evaluate the adoption of online learning by students in Zimbabwean universities. A descriptive online survey employing questionnaires to collect data on the adoption of eLearning by Zimbabwean universities students was used. Results indicated various eLearning platforms have been introduced in Zimbabwean universities though there is a need for eLearning infrastructure to be availed, students to be trained or students to effectively adopt the eLearning

A Singular Function Algorithm for Packing the Protocol Description Unit Packet

A new sequential singular function algorithm for packing Protocol Description Unit packets in the Short Message Mobile Originated Point-to-Point service is proposed. The single function algorithm simplifies the Short Message Entities programming where ATtention Commands are used to link Switched on Mobile Stations with Service Centers. This is in mode 0 of the short message service transmission. This paper shows that by using, only one single string function, the “Mid” or “Substring” function, it is still possible and is simpler to encode all the metadata contained in the Transport Protocol Data Unit frame of the Submit Protocol Description Unit packet. Our results show that, this proposed algorithm, always outputs 100% perfectly accurate packets for any combination of header and user data payload submitted in hexadecimal octets or decimal semi-octet format. It is thus possible for programmers not only to manipulate the distinct fields of the header data but also to modify the metadata using that single function only

The contribution of tropical cyclones to the atmospheric branch of Middle America's hydrological cycle using observed and reanalysis tracks

Middle America is affected by tropical cyclones (TCs) from the Eastern Pacific and the North Atlantic Oceans. We characterize the regional climatology (1998-2016) of the TC contributions to the atmospheric branch of the hydrological cycle, from May to December. TC contributions to rainfall are quantified using Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) product 3B42 and TC tracks derived from three sources: the International Best Track Archive for Climate Stewardship (IBTrACS), and an objective feature tracking method applied to the Japanese 55-year and ERA-Interim reanalyses. From July to October, TCs contribute 10-30% of rainfall over the west and east coast of Mexico and central Mexico, with the largest monthly contribution during September over the Baja California Peninsula (up to 90%). TCs are associated with 40-60% of daily extreme rainfall (above the 95th percentile) over the coasts of Mexico. IBTrACS and reanalyses agree on TC contributions over the Atlantic Ocean but disagree over the Eastern Pacific Ocean and continent; differences over the continent are mainly attributed to discrepancies in TC tracks in proximity to the coast and TC lifetime. Reanalysis estimates of TC moisture transports show that TCs are an important moisture source for the regional water budget. TC vertically integrated moisture flux (VIMF) convergence can turn regions of weak VIMF divergence by the mean circulation into regions of weak VIMF convergence. We discuss deficiencies in the observed and reanalysis TC tracks, which limit our ability to quantify robustly the contribution of TCs to the regional hydrological cycle

Defective Lamin A-Rb Signaling in Hutchinson-Gilford Progeria Syndrome and Reversal by Farnesyltransferase Inhibition

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare premature aging disorder caused by a de novo heterozygous point mutation G608G (GGC>GGT) within exon 11 of LMNA gene encoding A-type nuclear lamins. This mutation elicits an internal deletion of 50 amino acids in the carboxyl-terminus of prelamin A. The truncated protein, progerin, retains a farnesylated cysteine at its carboxyl terminus, a modification involved in HGPS pathogenesis. Inhibition of protein farnesylation has been shown to improve abnormal nuclear morphology and phenotype in cellular and animal models of HGPS. We analyzed global gene expression changes in fibroblasts from human subjects with HGPS and found that a lamin A-Rb signaling network is a major defective regulatory axis. Treatment of fibroblasts with a protein farnesyltransferase inhibitor reversed the gene expression defects. Our study identifies Rb as a key factor in HGPS pathogenesis and suggests that its modulation could ameliorate premature aging and possibly complications of physiological aging

Keeping It Real: Making Space for Play in Early Education Policy and Practice

This chapter considers how the pedagogical framing of preschool activity as a preparation for a school, may be in conflict with an international consensus advocating allowing children greater control of some of their activities in preschool. The first sometimes promotes an early start to more formal learning, while the second proposes that personal responsibility and self-control and can lead to longer lasting benefits resulting from preschool experiences. A case study of changing policy and practice in Kazakhstan is used to illustrate the tensions between these two models of learning. Qualitative, semi-structured interviews with practitioners in the preschool environment were used to explore how national standards documents interact with underlying beliefs about the nature of learning in the formation of practice. The findings suggest that, as in other countries, the intention to increase child-led pedagogy may be inhibited by existing classroom-based expectations of children’s participation. The chapter considers how participatory research in play environments might help to increase awareness of the value of child-led play by focusing increased attention on how play supports learning

What’s a (Childless) Man Without a Woman? The Differential Importance of Couple Dynamics for the Wellbeing of Childless Men and Women in the Netherlands

Using rich couple data from the Netherlands Kinship Panel Study, we investigated to what extent there were gender differences in couple dynamics within childless couples (N = 163). Though the childless partners reported similar relationship satisfaction, we found gender differences in the link between relationship conflict and relationship satisfaction - the childless men were more strongly affected by the negative aspects of the partnership. This gender difference was not evident for the association between partner support and relationship satisfaction - the positive aspects of the partnership were equally important for the male and the female childless partners. Furthermore, the association between relationship satisfaction and health was stronger for the childless men than for the childless women and this difference was particularly evident when the levels of relationship satisfaction were low. These results indicate that when they are in unsatisfying romantic relationships, childless men are at a greater risk than childless women of physical and mental ill health

An exploration of the role of perceived social support, coping, and resilience in the academic motivation of parentified black college students

This study examined the lives of parentified Black college students who were raised in single parent female-headed households. Participants in this study came from distressed family situations with a mother who currently experiences or has experienced: mental illness, substance abuse, incarceration, physical disability, medical condition, victim of abuse, irresponsibility, or who is deceased. The purpose of this study was to examine their college experiences including the push and pull factors they experienced from their families of origin while pursuing their degrees. This population is important to study because they are largely unrecognized in college settings. This study consisted of 121 male and female current undergraduate and graduate students and recent college graduates. Participants were administered a series of scales that measured parentification, academic motivation, perceived social support, coping, and resilience. Analysis yielded significant results including meaningful relationships between the main constructs: Parentification, Resilience, Perceived Social Support, Africultural Coping, Academic Motivation, and Gender. Furthermore, these variables, when combined, were significant predictors of academic motivation in parentified college students. Although there were no significant predictors of resilience in parentified college students, perceived social support, particularly family support was most strongly correlated with resilience. Furthermore, there were significant gender differences in academic motivation, but no noteworthy gender differences on any of the other main constructs for this study. The dissertation will also explore practical applications of the findings and suggestions for future research
