Adjuncts and the Chimera of Academic Freedom

The last 40 years have seen a dramatic shift in the hiring, evaluation and promotional structures prevalent in higher education. While the model of a largely full time, tenure-track faculty continues to be the ideal of most academic institutions, economic, political and social changes have eroded that model. A substantial percentage, typically a majority, of college and university faculty are now hired on a contingent or part-time basis, with fiscal and other conditions determining job security, compensation, professional advancement, and an opportunity to participate in governance of departments and institutions. This paper examines the unseen impact that such hiring practices have on professionalism and academic freedoms, not only for contingent faculty themselves but for faculty as a whole. We conclude that the current, two-class faculty system not only erodes collegiality and cohesion, but inhibits the quest for knowledge, wisdom and social justice that are a core mission of higher education

Examination of Eco-Behavioral Assessments Designed for Understanding Complex Behaviors and Environments.

Second-generation intervention research requires methods for overcoming challenges to understanding complex learning ecologies and interactions of students. Eco-behavioral assessments (EBAs) are one solution to past intervention research challenges. EBAs record the effects of ecological variables in students’ behavior and daily interactions. The utility of EBAs in second-generation research has increased substantially. Numerous EBAs now exist for use with all ages of learners and provide a valid, reliable, and cost effective method for intervention research. This paper examines 18 EBAs as well as software systems designed to support and enhance the use of EBAs. The examination serves as a comprehensive resource to better understand how EBAs can be used in answering complex questions about students’ learning and for advancing second-generation research

Identities relating six members of the Fibonacci family of sequences

In this paper, we prove several identities each relating a sum of products of three terms coming from different members of the Fibonacci family of sequences with a comparable sum whose terms come from three other sequences. These identities are obtained as special cases of formulas relating two linear combinations of products of three generalized Fibonacci or Lucas sequences. The latter formulas are in turn obtained from a more general generating function result for the product of three terms coming from second-order linearly recurrent sequences with arbitrary initial values. We employ algebraic arguments to establish our results, making use of the Binet-like formulas of the underlying sequences. Among the sequences for which the aforementioned identities are found include the Fibonacci, Pell, Jacobsthal and Mersenne numbers, along with their associated Lucas companion sequences

Diseño de oficinas en el Mediterráneo. La importancia del bienestar, la salud y el rendimiento de los usuarios

Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the existence of different ideal parameters for different levels of task complexity (one of the dimensions that characterizes work patterns) in the Mediterranean climate; and open new avenues of research to build up a specific Smart and Sustainable Offices (SSO) model and further systemic design-support tools.Estudios previos han investigado la influencia de la calidad del ambiente interior (CAI) de las oficinas en el bienestar, salud y rendimiento de los empleados. Sin embargo, no parecen haberse explorado explícitamente cuáles son las condiciones ambientales apropiadas para los diferentes patrones de trabajo que conviven en estos espacios. Este artículo presenta los resultados de un estudio empírico, basado en mediciones sincronizadas de diferentes parámetros CAI (i.e., ruido, iluminación y temperatura), y el bienestar, la salud y el rendimiento de 71 empleados ubicados en doce espacios de oficinas de la Comunidad Valenciana durante tres periodos, considerando invierno y verano. Estos resultados referentes al primer invierno monitorizado, sugieren la existencia de diferentes parámetros óptimos asociados a diferentes niveles de complejidad de la tarea para el clima mediterráneo; y abren nuevas vías de investigación para establecer un modelo de Oficinas Inteligentes y Sostenibles (SSO) y desarrollar herramientas de apoyo al diseño y la gestión de las mismas

Menopause and diabetes : EMAS clinical guide

Introduction: Whether menopause increases the risk of type 2 diabetes mellitus (T2DM) independently of ageing has been a matter of debate. Controversy also exists about the benefits and risks of menopausal hormone therapy (MHT) in women with T2DM. Aims: To summarise the evidence on 1) the effect of menopause on metabolic parameters and the risk of T2DM, 2) the effect of T2DM on age at menopause, 3) the effect of MHT on the risk of T2DM, and 4) the management of postmenopausal women with T2DM. Materials and methods: Literature review and consensus of experts' opinions. Results and conclusion: Metabolic changes during the menopausal transition include an increase in and the central redistribution of adipose tissue, as well as a decrease in energy expenditure. In addition, there is impairment of insulin secretion and insulin sensitivity and an increase in the risk of T2DM. MHT has a favourable effect on glucose metabolism, both in women with and in women without T2DM, while it may delay the onset of T2DM. MHT in women with T2DM should be administered according to their risk of cardiovascular disease (CVD). In women with T2DM and low CVD risk, oral oestrogens may be preferred, while transdermal 17 beta-oestradiol is preferred for women with T2DM and coexistent CVD risk factors, such as obesity. In any case, a progestogen with neutral effects on glucose metabolism should be used, such as progesterone, dydrogesterone or transdermal norethisterone. Postmenopausal women with T2DM should be managed primarily with lifestyle intervention, including diet and exercise. Most of them will eventually require pharmacological therapy. The selection of antidiabetic medications should be based on the patient's specific characteristics and comorbidities, as well on the metabolic, cardiovascular and bone effects of the medications.Peer reviewe

Empirical investigation to explore potential gains from the amalgamation of Phase Changing Materials (PCMs) and wood shavings

The reduction of gained heat, heat peak shifting and the mitigation of air temperature fluctuations are some desirable properties that are sought after in any thermal insulation system. It cannot be overstated that these factors, in addition to others, govern the performance of such systems thus their effect on indoor ambient conditions. The effect of such systems extends also to Heating, Ventilation and Air-conditioning (HVAC) systems that are set up to operate optimally in certain conditions. Where literature shows that PCMs and natural materials such as wood-shavings can provide efficient passive insulation for buildings, it is evident that such approaches utilise methods that are of a degree of intricacy which requires specialist knowledge and complex techniques, such as micro-encapsulation for instance. With technical and economic aspects in mind, an amalgam of PCM and wood-shavings has been created for the purpose of being utilised as a feasible thermal insulation. The amalgamation was performed in the simplest of methods, through submerging the wood shavings in PCM. An experimental procedure was devised to test the thermal performance of the amalgam and compare this to the performance of the same un-amalgamated materials. Comparative analysis revealed that no significant thermal gains would be expected from such amalgamation. However, significant reduction in the total weight of the insulation system would be achieved that, in this case, shown to be up to 20.94%. Thus, further reducing possible strains on structural elements due to the application of insulation on buildings. This can be especially beneficial in vernacular architectural approaches where considerably large amounts and thicknesses of insulations are used. In addition, cost reduction could be attained as wood shavings are significantly cheaper compared to the cost of PCMs
