Challenged academy: Engagement after neoliberalism
Market-driven educational policies and advances in information technology may assure greater accountability in public universities; however, the trend toward increased standardization strengthens the “machine’s” ability to appropriate the task of teaching. The challenge for college faculty is to sustain student-centered teaching and learning methods in the face of neoliberal reforms.Market-driven educational policies and advances in information technology may assure greater accountability in public universities; however, the trend toward increased standardization strengthens the “machine’s” ability to appropriate the task of teaching.

Development of an empirically based dynamic biomechanical strength model
The focus here is on the development of a dynamic strength model for humans. Our model is based on empirical data. The shoulder, elbow, and wrist joints are characterized in terms of maximum isolated torque, position, and velocity in all rotational planes. This information is reduced by a least squares regression technique into a table of single variable second degree polynomial equations determining the torque as a function of position and velocity. The isolated joint torque equations are then used to compute forces resulting from a composite motion, which in this case is a ratchet wrench push and pull operation. What is presented here is a comparison of the computed or predicted results of the model with the actual measured values for the composite motion
Happiness, Life Satisfaction, Well-being: Survey Design and Response Analysis
Several well-established surveys ask questions in order to measure subjective well-being. In some questionnaires, questions relate to happiness, in others, to individual well-being or satisfaction or to both happiness and satisfaction. In the literature of happiness, several papers have compared responses to these questions using available national and international data. However, employed data sets make it hard to properly disentangle wordings or scale effects from other survey design or survey administration
effects. For this reason, we design a single ad hoc survey in which we ask the same respondents to answer more than one well-being question. In addition, we use standardized scales across questions. We show that wording clearly matters: each subject self-reports her/his own happiness, life satisfaction, and well-being differently. We found that subjects do not perceive themselves as equivalent to one another and their determinants turn out to be different. Moreover, we find that the use of different scales
leads to different results. However, the coefficients of the determinants across different notions of welfare and across different scales never reverse the sign

Science and technology are very helpful in order to accelerate human work, for this reason human resources are needed that have high productivity and work efficacy so that they are able to produce the latest innovations that can meet market share needs. Education is one attempt that made to form human resources so that they can become someone who is able to analyze and be able to create the latest innovations. Many educational practitioners believe that the use of media or tools really helps the learning process activities both inside and outside, especially helping to improve student learning outcomes. In the Family Welfare Education Undergraduate Program with a concentration in Cosmetology, Makassar State University, there is a bun styling course, one of the subjects of which is Simpolong Tettong bun. The learning method currently established is a conventional learning system with the lecturer as the main source who demonstrates how to make Simpolong Tettong bun. This textbook on the Simpolong Tettong bun material was created by the author himself and is expected to add to the repertoire and references of learning media for bun styling courses. Why a textbook? Because it contains tutorials with practical explanations, easy to brought along and re-read anytime and anywhere. Research and Development (R&D) is a type of research which is used for produce certain products, and examine the efficacy of these products. The development model used by researchers is the Thiangarajan model (1974) using the 4-D model, by the definition of Define, Design, Development and Dissemination, because it is more appropriate to use as a principle to develop teaching materials that aim to improve student learning outcomes in PKK Department of Cosmetology Concentration at FT UNM
Neuroinflammatory mechanisms in ischemic stroke: Focus on cardioembolic stroke, background, and therapeutic approaches
One of the most important causes of neurological morbidity and mortality in the world is ischemic stroke. It can be a result of multiple events such as embolism with a cardiac origin, occlusion of small vessels in the brain, and atherosclerosis affecting the cerebral circulation. Increasing evidence shows the intricate function played by the immune system in the pathophysiological variations that take place after cerebral ischemic injury. Following the ischemic cerebral harm, we can observe consequent neuroinflammation that causes additional damage provoking the death of the cells; on the other hand, it also plays a beneficial role in stimulating remedial action. Immune mediators are the origin of signals with a proinflammatory position that can boost the cells in the brain and promote the penetration of numerous inflammatory cytotypes (various subtypes of T cells, monocytes/macrophages, neutrophils, and different inflammatory cells) within the area affected by ischemia; this process is responsible for further ischemic damage of the brain. This inflammatory process seems to involve both the cerebral tissue and the whole organism in cardioembolic stroke, the stroke subtype that is associated with more severe brain damage and a consequent worse outcome (more disability, higher mortality). In this review, the authors want to present an overview of the present learning of the mechanisms of inflammation that takes place in the cerebral tissue and the role of the immune system involved in ischemic stroke, focusing on cardioembolic stroke and its potential treatment strategies
Analytical Approach for Modelling the Pull-Out Mechanism of Recycled Synthetic Fibres in Fibre-Reinforced Concrete (FRC)
This study presents a simple one-dimensional analytical model describing the pull-out process of an elastic fibre embedded in a cement matrix, which captures the ductile behaviour of Fibre Reinforced Concrete (FRC) elements. The shear stress arising at the frictional interface between fibre and matrix during the pull-out is assumed to increase with the slippage distance, as a consequence of the growing abrasion of the fibre surface. The equilibrium conditions between the external axial load and the interfacial shear stress are imposed with reference to the undeformed configuration. The model is validated through comparison with both experimental data obtained by testing partially recycled polymeric fibres embedded in a cement matrix, and several datasets available in the literature comprising polypropylene fibres with and without silica coatings. The proposed model can properly describe the response of synthetic fibres that exhibit considerable axial elongation and slip-hardening interface behaviour. However, it may also predict the non-linear relation between the tensile load and the fibre displacement for different kinds of fibre, by setting adequately the constitutive parameters
Female Leadership and Gender Gap within Firms: Evidence from an Italian Board Reform
Over the last decade, several countries have followed the Norwegian example and introduced laws mandating gender quota for corporate board membership. The main aim of these laws is breaking the \u201cglass ceiling\u201d which prevents women from advancing into top corporate positions. In this paper, we evaluate the Italian law of 2011, which installed a step-wise increase in gender quota that remain effective for three consecutive board renewals of listed limited liability forms. We link firm-level information on board membership and board election dates with detailed employment and earnings records from the Social Security registers. Exploiting the staggered introduction of the gender quota regulation and variation in board renewals across firms, we evaluate the effect of the board gender composition on measures of gender diversity in top positions over a period of 4 years. While the reform substantially raised the female membership on corporate boards, we find no evidence of spillover effects on the representation of women in top executive or top earnings positions. Our results confirm the findings by Bertrand et al. (2018) who study the introduction of a gender quota for board members in Norway. Given that Italy is a much less egalitarian society than Norway, with a larger scope of establishing gender equality, our results confirm that board quota policies alone are ineffective in raising female representation in top corporate positions, at least in the short run
Information, formation and training for the maintenance operations: the lesson learned from fatal accidents
The list of possible machinery / equipment-related injuries is as long as it is worrying; they represent a non-negligible part of the total accidents in most industrial sectors, in terms of both numbers and severity, in normal conditions and during the maintenance operations.
Lack of maintenance or inadequate maintenance can lead to dangerous situations, accidents and health problems; but, at the same time, maintenance itself is a high-risk activity due to special hazards resulting from the particular nature of the work. Moreover, the workers involved are more likely than other employees directly exposed to the risks, since direct contact between the worker and the machinery to be maintained cannot be substantially reduced
