Dimensions of higher education and the public good in South Africa

The focus is on the micro-possibilities of student capabilities formation as the end of public-good higher education, rather than on a systems or organizations approach more commonly found in discussions of the public good and higher education. This does not discount other valuable public-good ends. Using South Africa as a global South context, a capability-based approach to the public good of higher education is proposed for its humanizing ethic, attention to fair opportunities, and participation in terms of what students are able to do and to be in and through higher education. A capability frame is complemented by thinking about decoloniality and epistemic justice to help identify central higher education capabilities. The three proposed intersecting capability dimensions are as follows: personhood self-formation, epistemic contribution, and sufficiency of economic resources, intended to guide university practices and policy interventions in the direction of the public good. By populating the space of the public good with capabilities, a shift is made away from micro-economics which see the public good as a reductionist space of commodities and human capital development. Higher education is rather understood as having both instrumental and intrinsic value, generating an alternative logic to that of neo-liberalism, and an individualist ontology of competition and untrammeled markets. The pressures of the global context are acknowledged so that the public good is understood as both “ideal-aspirational” but also “practical-feasible” in the light of local South African conditions. An expanded capability-based framing would contribute to reducing higher education inequalities as a public-good and public-accountable contribution by universities.     

Quality Assurance and Evaluation through Brazilian lenses: an exploration into the validity of umbrella concepts

In our present research we address the question of whether it is valid to apply the Quality Assurance and Evaluation (QAE) umbrella concept, which was formulated to explain new phenomena in European educational governance, to similar developments in Brazilian basic education. This led us to reflect on the possible pitfalls and potential strengths of using umbrella concepts as analytical tools. This article presents this exploration and its operationalisation. We confronted in-built assumptions in QAE with the contested, consensual and creative use of the notion of quality in Brazilian basic education, and looked for relationships. Our analysis shows that the Brazilian developments reiterate the relationships concerning global interconnectivity, and challenges those pertaining to conformity. We argue that the main risks of using umbrella concepts seem to concern the re-production of understandings, which frequently leads to the disregarding of deviation.     

Creating an LNG ready worker: British Columbia’s blueprint for extraction education

Since 2011, the government of British Columbia (BC) has focused on building the Canadian province’s economy through the development of a Liquefied Natural Gas (LNG) sector. In service of this endeavour, the government launched the Skills for Jobs Blueprint, which attempts to more clearly align BC’s education system with resource extraction industries. In this paper, I argue that at the heart of this policy is the idea of education for, through, and as extraction. Conceptually, ‘extraction education’ focuses on supply (what we can take out of the earth, institutions, and individuals) rather than demand (what is needed to put into the educational system to meet needs of the land, institutions, communities, and individuals), and is problematic on environmental, economic, employment, equity, and educational fronts. In theorising ‘extraction education’ I extend Freire’s ideas on ‘banking education’ and briefly explore dialogic, problem-posing counters to it.     

Alternating current-dielectrophoresis driven on-chip collection and chaining of green microalgae in freshwaters

The capability of the AC dielectrophoresis (DEP) for on-chip capture and chaining of microalgae suspended in freshwaters was evaluated. The effects of freshwater composition as well as the electric field voltage, frequency, and duration, on the dielectrophoretic response of microalga Chlamydomonas reinhardtii were characterized systematically. Highest efficiency of cell alignment in one-dimensional arrays, determined by the percentage of cells in chain and the chain length, was obtained at AC-field of 20 V mm⁻¹ and 1 kHz applied for 600 s. The DEP response and cell alignment of C. reinhardtii in water sampled from lake, pond, and river, as well as model media were affected by the chemical composition of the media. In the model media, the efficiency of DEP chaining was negatively correlated to the conductivity of the cell suspensions, being higher in suspensions with low conductivity. The cells suspended in freshwaters, however, showed anomalously high chaining at long exposure times. High concentrations of nitrate and dissolved organic matter decrease cell chaining efficiency, while phosphate and citrate concentrations increase it and favor formation of longer chains. Importantly, the application of AC-field had no effect on algal autofluorescence, cell membrane damage, or oxidative stress damages in C. reinhardtii.     

Acute intraocular pressure changes during isometric exercise and recovery: The influence of exercise type and intensity,and participant´s sex

ABSTRACT

We assessed the intraocular pressure (IOP) behaviour during a 1-minute period of isometric physical effort and the immediate 1-minute of recovery in the mid-thigh clean pull and squat exercises at three different intensities. Twenty physically active individuals performed the isometric mid-thigh clean pull and squat exercises at three intensities (0% [low-intensity], 25% [medium-intensity] and 50% [high-intensity] of the maximum isometric force). IOP was semi-continuously measured by rebound tonometry. There was a statistically significant effect of exercise intensity on IOP (p < 0.001, ?_p² = 0.416), observing that IOP increments were positively associated with exercise intensity. The mid-thigh clean pull and squat exercises did not demonstrate differences (p = 0.510), and also, no differences were observed between men and women (p = 0.683). The IOP changes during the isometric physical effort showed a positive linear behaviour in all conditions (r = 0.70 to 0.96). IOP returned to baseline levels after 8 seconds of recovery. Our data showed a progressive and instantaneous IOP increment during isometric exercise, which was positively associated with exercise intensity. IOP changes were independent on the type of exercise and participant´s sex. After exercise, IOP rapidly (≈ 8 seconds) returned to baseline levels.     

The relevance of innovative school architecture for school principals

In many cases, innovative forms of learning require innovative concepts of using space in school. However, so far there has been a lack of research concerning the perspectives of school principals as important stakeholders in the adoption of alternative school architecture. The present study examines the importance of alternative school architecture in a sample of 1164 principals (56% females, mean-age 52.7 years) in Austria. An online questionnaire was conducted, containing questions about the school building, innovative forms of learning, and principals’ level of information, perceptions, and thoughts on the relevance of school architecture, as well as their motivation and self-efficacy. Results showed that principals are aware of the advantages of certain architectural elements, although these elements have been implemented in only a few schools. A high proportion of respondents report a lack of information about configurations of space that go beyond the traditional corridor-scheme. We conclude that although principals are in general open for the alternative configuration of space further efforts have to be made to overcome the obstacles that prevent principals from launching new concepts of using space, which are a lack of competitive resources and knowledge as well as an inadequate professional network.     

Exploring the relationship between school discipline referrals and delinquency

There is a growing concern about violent and destructive behaviors of youth that require intervention by juvenile justice and youth‐serving agencies. This concern has led many to conclude that schools and community agencies must increase efforts to prevent juvenile delinquency and to provide programs that will facilitate rehabilitation, education, and vocational training for youth already involved. A clear understanding of the nature and range of behaviors that result in juvenile crime is needed in order to develop programs and interventions that can be expected to lead to beneficial changes for youth and for society as a whole. The purpose of this article is to describe the relationship between school behaviors and youth characteristics in school (e.g., discipline referrals, teacher nominations, nomothetic ratings) and referrals to juvenile authorities (e.g., illegal behaviors). We describe a strategy of using teacher nominations, school discipline referrals, and community arrest data to predict delinquent and violent behavior in youth. We outline data from a group of socially maladjusted middle school youth to illustrate the relationship between the two data sources and recommendations for identification and treatment of youth at risk for delinquency and antisocial behavior. © 2001 John Wiley & Sons, Inc.     

Stereotype Threat,Identification with Academics,and Withdrawal from School: Why the most successful students of colour might be most likely to withdraw

Claude Steele’s stereotype threat hypothesis posits that when there are negative stereotypes about the intellectual capacity of certain (stigmatised) groups, members of that group suffer aversive consequences; group members who are most strongly identified with the stigmatised domain in question (e.g., intellectual or academic ability) are those most likely to suffer the effects of stereotype threat. In education, it is widely held that personal investment in schooling should lead to more positive outcomes. However, highly‐invested individuals will most keenly experience the negative effects of stigma. Thus those most at risk for withdrawing from school among students of colour (who suffer a stigma of intellectual inferiority) could be those most invested in schooling. This hypothesis was tested by measuring identification with academics among a group of incoming students at a racially diverse inner‐city high school in the Midwest USA. Regardless of race, the students who most strongly identified with academics (they valued and considered academics central to the self) had higher GPAs, lower levels of absenteeism, and fewer behavioural referrals. However, among students of colour the most strongly identified were more likely to withdraw, while identification with academics did not significantly influence the withdrawal of Caucasian students. These results highlight the importance of providing a supportive environment that diffuses stereotype threat for all students, even those who appear to be academically successful.
