This paper builds on discussions of academic developers’ identity experienced as a discomfiting, troubled, and often marginal space. Three experienced academic developers, located in research-intensive institutions in three different countries, using auto-ethnographic writing and a shared narrative inquiry, explore moments of congruence and conflict. While there are elements that sustain them in their job, the categorisation of their role can impact on their ability to do their job, undermining their credibility. This can prevent them from engaging in research that could enrich practice in their institutions and inform institutional strategy or change the culture in teaching and learning. Instead they are forced into discomfit: having to defend their right to be involved in the institutional discussions. The most worrying issue is the pervasive trend in the change of academic developers’ status (from tenure-track academic peers to professionals). 相似文献

An analysis of the asynchronous behavior of the hysteresis machine is undertaken based on a “rectified” model of its structure. The hysteresis shell and the yoke of the rotor are assumed as being manufactured out of materials with finite conductivities. The field analysis undertaken via Maxwell's equations and Poynting's theorem shows the influence of the induced eddy currents on the machine performance at nonvanishing slips. The characteristics of the machine are computed as functions of slip, revealing three particularly interesting cases. 相似文献

The paper contributes to design discourse by drawing on Educational Design Research (EDR) that has been conducted into what we call a Zone of Possibility (ZoP) over the past seven years. We define a ZoP as a place where individuals can overcome the constraints of expectations and power structures to effect desired change. Specifically, this paper presents details of how our initial research question (RQ1) has evolved to the one presented in the conclusions (RQ2); both RQs are summarised below in the section “Research Questions.” To describe this evolution, the paper is presented as 3 cases (Confer, ZoP Stokes Croft and Google Lens in HE) that have provided insights to explore the concept of the ZoP and its implications for EDR. Specifically, one of the main conclusions is the importance of bridging positioning practices as “successful communication” and an understanding of social context in hybrid contexts (ie, the ZoP). 相似文献

RESUMENSe describe un programa de estimulación precoz llevado a cabo en un centro de educación especial, programa que se marcó dos objetivos principales: ofrecer al niño un ambiente rico en estímulos y mejorar la relación afectiva de los padres. El diagnóstico se hace a través de un enfoque multidisciplinar y se trabaja en cuatro áreas: desarrollo personal, control motor grueso, control motor fino y lenguaje. Es muy importante integrar a los padres en el programa educativo, ya que son los principales agentes educativos. En este sentido se trabaja a nivel tanto informativo (de forma individual y con sesiones programadas en la Escuela de Padres) como formativo (asesoramiento familiar individual). 相似文献

The analysis of the asynchronous behavior of the hysteresis machine is undertaken based on a model describing its cylindrical structure. Assuming that the hysteresis shell of the rotor is manufactured out of materials with finite conductivities, the influence of the induced eddy- currents on the machine performance is pointed out via Maxwell's equations and Poynting's theorem. The characteristics of the machine are computed as functions of slip and three interesting limiting cases are revealed. 相似文献

The properties of the hysteresis machine are analyzed on the basis of a cylindrical model. The electromagnetic field in the various regions of the motor is derived by field-theoretical methods (such as Maxwell's equations and Poynting's theorem), and the resulting parameters are applied in turn in determining torques and other relevant quantities. Three limiting particular cases of special interest are examined. 相似文献

According to most theories, in a simple contingency learning situation, excitatory learning occurs when the probability of the unconditioned stimulus in the presence of the conditioned stimulus (p1) is higher than the probability of the unconditioned stimulus in the absence of the conditioned stimulus (p2). In Rescorla and Wagner??s (1972) model, this prediction varies, depending on the parameters used. In the following experiments, we evaluated whether the difference between p1 and p2 that is required to produce excitatory conditioning is the same, independent of the specific value of p1, or whether this difference varies proportionally to p1??s value. To do so, an appetitive procedure of Pavlovian conditioning with rats was used. In four experiments, we compared different levels of contingency (low, medium and high) and found that the difference between p1 and p2 that is required to produce excitatory conditioning increases when the value of p1 is higher. The possibility of analyzing contingency learning as a discrimination between p1 and p2 is also discussed. 相似文献

ABSTRACTThis study aimed to compare the goodness of fit and the reliability of different regression models for fitting the force-velocity relationship (FV) of bench press (BP) and squat (SQ). Additionally, the reliability of the position on FV of the velocity (V1RM) and the force performed with the 1RM (F1RM) was explored. Nine rugby players and 12 judokas participated in this study. The FV of BP and SQ were obtained twice by a protocol performed until the 1RM. Individual FV were fitted by linear (LM), quadratic polynomial (PM), and exponential models (EM). Adjusted coefficients of determination of LM and PM (medians higher than 0.919) were higher than for EM. The reliability was higher for LM in comparison with PM. The reliability of V1RM was not acceptable (CV% = 19 and 18% for BP and SQ). High reliability was observed for F1RM (CV% = 3 and 2% for BP and SQ) and for the ratio between F1RM and the force-axis intercept of FV (CV% = 2 and 4% for BP and SQ). The reliability of the relative values of F1RM around 92 and 87% of F0 for BP and SQ suggests the use of these values for monitoring resistance training programmes. 相似文献

This paper demonstrates the importance of considering lived experiences of adjunct teaching staff during the introduction of automated student messaging services in a UK Business School. With cost-orientated moves to expanding online provision through emergent technologies and the growth of alternative HE strategies, traditional group-orientated student and tutor interactions are developing into a continuum. Automated messages aim to increase retention, and standardise the student experience in terms of academic qualification communications. These messages, however, have necessarily required tutors unlearning previous pedagogical support routines, thus changing academic roles and in consequence impacting academic identity processes. The investigation adds to emerging literature by examining the impact on a group of adjunct faculty staff during change introduction. Study into these changes to academic routines has value, as much existing retention literature privileges the institutional or student experience, and much of learning/unlearning literature is in a non-educational setting. 相似文献

This study aimed to compare the load-velocity and load-power relationships of three common variations of the squat exercise. 52 strength-trained males performed a progressive loading test up to the one-repetition maximum (1RM) in the full (F-SQ), parallel (P-SQ) and half (H-SQ) squat, conducted in random order on separate days. Bar velocity and vertical force were measured by means of a linear velocity transducer time-synchronized with a force platform. The relative load that maximized power output (Pmax) was analyzed using three outcome measures: mean concentric (MP), mean propulsive (MPP) and peak power (PP), while also including or excluding body mass in force calculations. 1RM was significantly different between exercises. Load-velocity and load-power relationships were significantly different between the F-SQ, P-SQ and H-SQ variations. Close relationships (R2 = 0.92–0.96) between load (%1RM) and bar velocity were found and they were specific for each squat variation, with faster velocities the greater the squat depth. Unlike the F-SQ and P-SQ, no sticking region was observed for the H-SQ when lifting high loads. The Pmax corresponded to a broad load range and was greatly influenced by how force output is calculated (including or excluding body mass) as well as the exact outcome variable used (MP, MPP, PP). 相似文献
