Community alliances and participatory action research as a mechanism for re-politicising social action for students in higher education

ABSTRACT Evidence from the UN World Youth Report (2015) suggests that young people, while increasingly disengaged with formal political processes, are motivated by cause-related social action. Higher Education (HE), through research and partnership, provides ideal learning spaces to explore cause-related social action. However, as HE partnership opportunities continue to be reframed under a narrative of employability and one-off participation, there is a risk that these experiences miss an opportunity to critically engage young people with issues at a socio-political level. This research paper considers the potential of participatory action research (PAR) as a pedagogical mechanism for re-politicising social action for students in a UK HE context. The project explores the experiences of 160 undergraduate students, working in partnership with 400 young children, aged 2–10 years, to investigate and co-construct their views and action concerning causes represented by local community organisations. Findings suggest that using participatory, youth-action approaches students shifted their self-identified positions from a non-social-orientated approach to establishing them as advocates for causes and children’s voices. We argue that PAR, as a learning experience, and service-learning pedagogy open up an alternative experience of social action through an educational context with engagement and consideration of social issues. In conclusion, we call for new alliances between HE, young people, and community organisations, to produce, through enquiry, critical knowledge aimed at social transformation, which can open-up authentic democratic spaces within the learning communities in HE and its networks.
The Influence of Daily Price Extremes on Short-Term Stock Returns

Abstract This paper explores whether investors use daily price extremes as reference points for short-term investing decisions by examining their relation with returns. Excess momentum returns are observed for days in which prices open outside of the previous day’s highest or lowest trading price. This relation is robust to market direction and is consistent over time. Contrary to the disposition effect, the evidence also shows that an additional momentum effect is present when the markets have been closed for two days and open lower than the previous trading day’s low, but a lesser (although significant) effect is documented for openings’ higher than the previous high.
Does More Mean Less?: Interest Surplus and the Gender Gap in STEM Careers

The persistent gender gap in STEM (Science, Technology, Engineering, and Math) career choice represents a perplexing problem for researchers and policy makers alike. We contribute to the body of research on the gender gap in STEM careers by testing a “surplus model” of vocational interests as a predictor of STEM career choice. The model suggests that, controlling for ability, female adolescents with strong STEM-related interest should be less likely to pursue STEM careers when they also have strong interests in other areas, due to wider career options. We tested the surplus model in a large national longitudinal data set and translated the results into differences in annual wages. Our findings illuminate the predictive validity of a surplus model of interests on STEM career choice across gender, provide insight into the gender gap in STEM, and suggest opportunities for future research.
Coordinating the Behavior of Different Agents in Distribution Networks – A Review

This paper provides a detailed overview of the current state of scientific literature on the coordination of different agents in smart distribution systems. The coordination of agents can be market-driven or network-related. As an important market-driven measure, approaches that allow to reflect time-variable retail tariffs are investigated. Trading flexibility at smart markets is considered to be a central approach for network-related coordination in the future. As market-driven and network-related coordination of agents can be contradictory, also literature that considers both is discussed. Finally, a conceptual framework for the analysis of alternative market regimes in distribution networks is developed on basis of the reviewed literature.
Cyberbullying and its relationship with physical, verbal, and relational bullying: a structural equation modelling approach

Abstract The article focuses on the contentious relation between cyberbullying and physical, verbal, and relational bullying. Drawing on items from the Olweus questionnaire, the study used confirmatory factor analysis and structural equation modelling, and latent factors of bullying were fitted to the data. Different background variables were related to cyberbullying and traditional bullying factors. The results revealed high correlations between physical, verbal, and relational bullying. While the relations between cyberbullying and physical and verbal bullying were modest to moderate, a substantial correlation between cyberbullying and relational bullying was observed (.69). Further, it was noted that the level of anxiety had a stronger relation with the cyberbullying factor, while number of friends was similarly related to all four bullying factors. The implications of the high relation between cyber and relational bullying, as well as their similar association with the covariates, were discussed.
Fast transport of water in carbon nanotubes: a review of current accomplishments and challenges

ABSTRACT The intriguing mass transport properties of carbon nanotubes (CNTs) have received widespread attention, especially the rapid transport of water through CNTs due to their atomically smooth wall interiors. Extensive research has been dedicated to the comprehension of various aspects of water flow in contact with CNTs, the most prominent ones being the studies on slip and flow rates. Experimental and computational studies have confirmed an enhanced water flow rate through this graphitic nanoconfinement. However, a quantitative agreement has not yet been attained. These disparities coupled with incomplete knowledge of the mechanisms of water transport at nanoscale regimes are hindering the possibilities to integrate CNTs in numerous nanofluidic applications. In the present review, we focus on the slip and flow rates of water through CNTs and the factors influencing them. We discuss the key sources of discrepancies in water flow rate and suggest directions for future study.

The study aims to develop concepts originating through empirical research models to build superior competitiveness and optimal performance achievement. Therefore, to bridge these goals, the study addresses several indicators/items as a novelty, namely, entrepreneurship insight factors, market orientation, knowledge-sharing, innovation, managerial capability, product strategy, process and service improvement, resources capability to improve performance and increase competitiveness by empirical model direct, mediating and indirect effect. The total sample in this study is 497 eligible SMEs that partner with go-food in Makassar City. All research samples are the owner or the person in charge of the business; the data collection period is from May to December 2019. Data are collecting using a survey with 64 construct questions, summarized in seven manifest variables. The research method uses quantitative tools, with SMART-PLS as a statistical tool. This study develops sixteen hypotheses; all of the hypotheses are supported both directly, indirectly, and mediated. The study also found that the link based on CCT, RBV, and TAM Theory is the right choice of theories, as the foundation of this study was very reliable and valid. Indeed, all of the grounded methods have implications both in theory and its main application for the business in the online marketplace.
Molecular phylogeny and biogeography of Triplophysa stone loaches in the Central Chinese Mountains

The geological structure and history of mountains often cause highly complex patterns of evolution. The origin and diversity of the genus Triplophysa is considered to be closely associated with the rapid and persistent rise of the Qinghai-Tibet Plateau (QTP). Species of the genus are widely distributed in the QTP and adjacent regions, and are strongly adapted to its extreme environments. However, the Central Chinese Mountains (CCM), which are far apart from the QTP, also have many Triplophysa populations and yet their taxonomy, phylogeny and origin are unknown. We used three mitochondrial genes of 266 individuals from 29 sites in the CCM to shed light on the evolution of these Triplophysa populations. Phylogenetic analyses and species delimitation revealed seven distinct molecular operational taxonomic units (mOTUs) in the CCM, each with low genetic diversity. Molecular clock and biogeographic analyses suggested that vicariance events resulting from the rapid uplifting of the Qinling and Taihang Mountains initialized diversification in the Pliocene. During the early Pleistocene, dispersal events in the central parts of the Yellow River drainage altered genetic diversity and led to the currently observed biogeographic patterns. Our results suggest the presence of at least six species of Triplophysa in the CCM and more are likely to be discovered in the future.
GASTRIC VOLVULUS: A Case Report and Literature Review

Background: Gastric volvulus is a rare surgical emergency that causes an upper digestive obstruction due to a rotation of the stomach greater than 180°. Observation: We report the case of a 2-year-old patient referred from a health care facility for incoercible vomiting. On admission, the clinical examination revealed that the condition started about 1 month back with poor general and nutritional condition. Pyloric stenosis was suspected but this hypothesis was rejected based on abdominal ultrasound. Further investigations were done with an abdominal X-ray and an upper gastrointestinal barium study which led to the conclusion of an organo-axial gastric volvulus. The patient died in the course of treatment. Conclusion: Gastric volvulus is an often-misunderstood condition. Upper gastrointestinal barium study remains the gold standard of diagnosis. Its management is surgical.
Repurposing of thalidomide and its derivatives for the treatment of SARS‐coV‐2 infections: Hints on molecular action

The SARS‐coV‐2 pandemic continues to cause an unprecedented global destabilization requiring urgent attention towards drug and vaccine development. Thalidomide, a drug with known anti‐inflammatory and immunomodulatory effects has been indicated to be effective in treating a SARS‐coV‐2 pneumonia patient. Here, we study the possible mechanisms through which thalidomide might affect coronavirus disease‐19 (COVID‐19).
Properties of bone from Catfish heads and frames

Abstract The objective of this paper was to evaluate methods of producing purified Catfish bone fractions from Catfish frames and heads and determine the composition of the purified bone fraction. Fresh samples of Catfish frames and heads were obtained from a large commercial Catfish processor. Triplicate samples were processed for all treatments. Two methods were developed to remove nonbone tissue from the frames: (a) use of a proteolytic enzyme to digest the nonbone tissues and (b) after boiling the frames, removal of the nonbone tissues with high‐pressure water. The ash, protein, and lipid contents of unprocessed dried frames were 17%, 33%, and 41%, respectively. After the enzymatic or high‐pressure water treatment processes, the frame bone compositions for the two processes were 62% and 54% ash, 35% and 33% protein, and 9% and 2% lipid, respectively. Bone from both processing treatments had a calcium content of 21%–25%, phosphorus content of 10%–11%, and contents of magnesium, manganese, zinc, and nickel were increased. Hydroxyproline content increased from 4% of the amino acids in the untreated bone to 7%–8% for the processed treatments. Tissues were removed from Catfish heads by digestion with a proteolytic enzyme and collection of the bone with a sieve. After the longest digestion period, dried head bone was 51% ash, 38% protein, and 7% lipid. The amino acid profiles showed high levels of hydroxyproline and lower levels of many essential amino acids. With increased enzymatic hydrolysis time, percent calcium and phosphorus increased. Results from this study will be used in the development of new value‐added food and feed ingredients from Catfish bone.
Inheritance pattern of resistance to Fusarium wilt (Fusarium oxysporum f. sp sesame) in sesame

Fusarium wilts (Fusarium oxysporum f.sp. sesame) is among of the most destructive soil-borne disease of sesame in Uganda. The disease may cause yield loss of up to 100% if not controlled. Breeding and use of resistant varieties is the most economic and eco-friendly solution to the disease since majority of sesame growers are resource constrained. Some genotypes were reported to be moderately resistant to the disease in Uganda. However its nature of inheritance was not studied. Successful breeding requires selection of suitable parents and whose pattern of inheritance of disease resistance is known. In this study, eight parental genotypes of sesame with different levels of resistance to Fusarium wilt pathogen were used in a full diallel to produce F1 progenies. The eight parents and F1 progenies were evaluated in the screen house under high pathogen pressure through artificial infection in an Alpha Lattice Design of three replicates. The results revealed that additive and non-additive gene actions contributed to controlling resistance to Fusarium wilt. However non-additive were more predominant which were signposted by moderate Baker’s ratio (53.9%) and low Coefficient of Genetic Determination narrow sense (h2 = 45.1%). Moreover, the study indicated that maternal effects have influence toward resistance to Fusarium wilt in sesame. Among eight parents used parent Sesim 2 (with EM% GCA effect 7.32, and DI% GCA effect -4.02) and EM15-1-5 (with EM% GCA effect 3.07%, and DI% GCA effect -11.58%) were good combiner parents for transmitting resistance and are recommended for use in breeding for Fusarium wilt resistance. Key words: Fusarium wilt, inheritance, incidence, resistance, sesame,
Towards Indicators for a Negative Emissions Climate Stabilisation Index: Problems and Prospects

The incongruence between the United Nations objective to hold global warming well below 2 °C and the rate of global emission reductions has intensified interest in negative emissions. Previous research has explored several pros and cons of individual negative emissions technologies. Systematised approaches to comparing and prioritising among them are, however, largely lacking. In response to this gap in the literature, this article reviews the scientific literature on indicators for designing negative emissions climate stabilisation value indexes. An index typically provides summary measures of several components, often denoted indicators. Utilizing a narrative review methodology, the article derives five categories of indicators underpinned by overlapping and often mutually reinforcing environmental and socio-economic values. A list of 21 indicators are proposed to capture both positive and negative values associated with effectiveness, efficiency, scale, risk, and synergies. While discussing indicators capable of providing guidance on negative emissions is timely, given the emerging shift away from pure emission reduction targets towards net-zero targets, numerous complexities are involved in determining their relative values. The results herein serve to inform policy making on the prioritisation and incentivisation of negative emissions technologies capable of delivering on the new objectives, and the results highlight the many risks and uncertainties involved in such exercises. The article concludes that systematic research on the comparison of NETs is incomplete. An iterative, interdisciplinary research programme exploring such questions has the potential to be extremely rewarding.
How Does Globalization Affect the Welfare State? Openness to Trade and Social Spending Patterns in 21 Countries, 1920-2000

This paper investigates the link between globalization, operationalized as openness to trade, and the welfare state, defined as social spending, in a panel of 21 countries from 1920 to 2000. It argues for a clear definition of globalization with clearly defined and testable data, and that social spending should be analyzed on the aggregate as well as by type of welfare program since the effect of globalization is probably not uniform. The paper finds notable divergences in openness and social spending between countries and regional groups across the century, but it negates a clear connection between small, typically open, economies and large welfare states. Openness to trade had different effects on different welfare programs but was positive for the growth of total social spending. There is hence some confirmation for the welfare state as a cushion for those losing out due to globalization, but it is not a uniform mechanism across all types of social spending and effect sizes were overall small compared to other variables. This was most notable in the positive impact on spending on unemployment benefits but was less straightforward in the positive impact on pension expenditure.
Knowledge acquisition, knowledge management strategy and innovation: An empirical study of Vietnamese firms

Abstract This paper examines two alternative views—universal and contingency—of the knowledge acquisition and innovation relationship in Vietnamese firms. Results from a survey of 130 companies show that knowledge acquisition has a positive effect on innovation. In addition, this study showed that in terms of direct effects on innovation results, the personalization strategy has a more important role than the codification strategy. However, among the two knowledge management (KM) strategies, only the codification strategy moderated the knowledge acquisition–innovation relationship. The findings also suggested that in order to achieve a high level of innovation results, the firm should not be overly dependent on the implementation of the codification strategy without paying due attention to personalization strategy. Furthermore, for firms at the nascent stage of development or those in developing countries like Vietnam, knowledge acquisition and personalization strategy can lead to innovation results.
Study of the Function and Dynamics of Myosin II and Actin in Cytokinesis: A Dissertation

Myosin II and actin are two major components of the ingressing cortex during cytokinesis. However, their structural dynamics and functions during cytokinesis are still poorly understood. To study the role of myosin II in cortical actin turnover, dividing normal rat kidney (NRK) cells were treated with blebbistatin, a potent inhibitor of the non-muscle myosin II ATPase. Blebbistatin caused a strong inhibition of actin filament turnover and cytokinesis. Local release of blebbistatin at the equator caused inhibition of cytokinesis, while treatment in the polar region also caused a high frequency of abnormal cytokinesis, suggesting that myosin II may play a global role. These observations indicate that myosin II ATPase is essential for actin turnover and remodeling during cytokinesis. To further study the mechanism of myosin II and actin recruitment to the cytokinetic furrow, equatorial cortex were observed with total internal reflection fluorescence microscope (TIRF-M) coupled with spatial temporal image correlation spectroscopy (STICS) and a new approach termed temporal differential microscopy (TDM). The results indicated at least partially independent mechanisms for the early equatorial recruitment of myosin II and actin filaments. Cortical myosin II showed no detectable directional flow toward the equator. In addition to de novo equatorial assembly, localized inhibition of disassembly appeared to contribute to the formation of the equatorial myosin II band. In contrast, actin filaments underwent a striking, myosin II dependent flux toward the equator. However, myosin II was not required for equatorial actin concentration, suggesting that there was a flux-independent, de novo mechanism. The study was then extended to retraction fibers found typically on mitotic adherent cells, to address the hypothesis that they may facilitate post-mitotic spreading. Cells with iv
Analysis of the Level of the Teacher Efficacy of Beginning Agriculture Teachers in Eswatini

Over the past decade, researchers continually emphasized the role of teacher efficacy in teaching effectiveness. A descriptive survey was used to investigate the level of teacher efficacy of beginning agriculture teachers in Eswatini. The population of the study were senior secondary school beginning agriculture teachers in Eswatini. The study is a census, involving all senior secondary school agriculture teachers who had up to five years of agriculture teaching experience. 161 agriculture teachers participated in the study. Data were collected using a self-administered modified Teachers’ Self-Efficacy Scale (TSES) with a . 92 reliability coefficient. The data were analysed using descriptive and inferential statistics. Beginning agriculture teachers were moderately efficacious in classroom management, instructional strategies and student engagement. Gender, subject specialization and affiliation to professional development bodies accounted for significant differences in teacher efficacy on selected agriculture teaching tasks. Beginning agriculture teachers are capable of getting the desired learning outcomes from senior secondary school agriculture students as indicated by the moderate level of teacher efficacy. Preservice teacher training programmes should strengthen curriculum content on ways of engaging students.
