Cell biology is an academic discipline that organises and coordinates the learning of the structure, function and molecular composition of cells in some undergraduate biomedical programs. Besides course content and teaching methodologies, the laboratory environment is considered a key element in the teaching of and learning of cell biology. The aim of this study was to determine students’ opinions about the quality of the teaching and learning environment in cell biology laboratory practice. For this study, we used a short form of the Science Laboratory Environment Inventory (SLEI), which we adapted and translated into Spanish. The questionnaire, administered to students enrolled in four undergraduate programs, consisted of 24 questions divided into four scales: integration of content, clarity of laboratory rules, cohesion between students and teachers, and quality of laboratory infrastructures and materials. The results suggested that (1) students positively assessed the learning environment provided for cell biology practice, (2) the short Spanish form of the SLEI was a valid, reliable instrument for evaluating student satisfaction, laboratory activities, the degree of cooperation between students and teachers, and theoretical and practical organisation of content and (3) the questionnaire detected differential perceptions of the learning environment based on gender and the program studied. 相似文献

OBJECTIVES: The present research was designed to study empathy in high-risk parents for child physical abuse. The main objective was to study if high-risk mothers and fathers, compared to low-risk mothers and fathers, presented more Personal distress, less Perspective-taking, less Empathic concern and a deficit in dispositional empathy toward their partner and children. METHOD: Based on their scores on the Abuse Scale of the CAP Inventory [J.S. Milner, The Child Abuse Potential Inventory: Manual, 2nd ed., Psytec Corporation, Webster, NC], 19 (9 fathers and 10 mothers) high- and 26 (12 fathers and 14 mothers) low-risk parents for child physical abuse were selected from a total sample of 331 parents of the Spanish general population. Both groups were statistically matched on sociodemographic variables. The Interpersonal Reactivity Index (IRI) [Catalog of Selected Documents in Psychology 10 (1980) 85] and the Parent/Partner Empathy Scale (PPES) [N.D. Feshbach, N. Caskey, A new scale for measuring parent empathy and partner empathy: factorial structure, correlates and clinical discrimination, 1985] were used to assess dispositional empathy. RESULTS: An interaction between risk status and gender for "Personal distress" and "Perspective-taking" was found. High-risk mothers for child physical abuse showed more "Personal distress" than low-risk mothers and low-risk fathers. High-risk fathers for child physical abuse showed less "Perspective-taking" than low-risk mothers and low-risk fathers. No difference between both groups was found for the IRI "Empathic concern" dimension. Moreover, high-risk, compared to low-risk, parents showed lower scores both on the "Empathy toward the partner" and on the "Empathy toward the child" dimensions of the PPES. No interaction between risk status and gender was found for the PPES dimensions. CONCLUSIONS: Findings of the present study supported the hypothesis that high-risk parents for child physical abuse show a deficit both in general empathy and in empathy toward their family members. Moreover, findings suggested the existence of a different pattern of deficits in empathy for high-risk fathers and high-risk mothers. 相似文献

The principal contribution of this note is to avoid the parametric resonance effect and attenuate the payload oscillations in an overhead-crane system subject to periodic variations in the base support. Considering an appropriate sliding output with relative degree one, we present the sliding mode control design based on the Super-Twisting Algorithm (STA), ensuring finite time convergence to the desired sliding surface for the linear periodic system with Lipschitz continuous matched and unmatched uncertainties bounded together by their gradients by known functions. The suggested approach also provides chattering phenomenon attenuation. Obtained results are verified experimentally. 相似文献

Community colleges have responded to the increased use of technology for instruction by providing support and professional development opportunities for faculty. However, differences in perceptions, expectations, and opportunities exist between full-time faculty at community colleges and their adjunct colleagues when it comes to adopting technology into instruction. Because adjunct faculty represent 68.5% of faculty teaching at community colleges (U.S. Department of Education, 2007), it is imperative to understand their intentions to integrate technology into instruction. This study adopted the Decomposed Theory of Planned Behavior (DTPB) as a theoretical framework to survey 130 community college adjunct faculty member's intentions to participate in technology integration. Multiple regression analyses were used to analyze the data collected. Results showed that DTPB was useful in explaining much of the variance in the intention to integrate technology into teaching by community college adjunct faculty. Results also suggested that community college administrators can play an important role toward increasing technology integration by adjunct faculty through leveraging types of influence in support of behavioral intention. Research implications for instructional technologists at community colleges indicated that professional development programs should be designed based on the significant predictors in the DTPB. 相似文献

Abstract The aim of this study was to analyse the influence of playing tactics, opponent interaction and situational variables on achieving score-box possessions in professional soccer. The sample was constituted by 908 possessions obtained by a team from the Spanish soccer league in 12 matches played during the 2009–2010 season. Multidimensional qualitative data obtained from 12 ordered categorical variables were used. Sampled matches were registered by the AMISCO PRO® system. Data were analysed using chi-square analysis and multiple logistic regression analysis. Of 908 possessions, 303 (33.4%) produced score-box possessions, 477 (52.5%) achieved progression and 128 (14.1%) failed to reach any sort of progression. Multiple logistic regression showed that, for the main variable “team possession type”, direct attacks and counterattacks were three times more effective than elaborate attacks for producing a score-box possession (P < 0.05). Team possession originating from the middle zones and playing against less than six defending players (P < 0.001) registered a higher success than those started in the defensive zone with a balanced defence. When the team was drawing or winning, the probability of reaching the score-box decreased by 43 and 53 percent, respectively, compared with the losing situation (P < 0.05). Accounting for opponent interactions and situational variables is critical to evaluate the effectiveness of offensive playing tactics on producing score-box possessions. 相似文献

It is generally accepted that preadolescents have a limited capacity to develop muscle hypertrophy in response to exercise compared with older populations; however, studies are scarce and conflicting. The main aim of the present study was to assess if playing tennis is associated with the hypertrophy of dominant pectoralis muscles (PM) in professional (PRO) and in prepubescent tennis players (PRE). A secondary aim was to assess if the degree of asymmetry of PM is greater in PRO than PRE. The volume of PM of both sides was determined using magnetic resonance imaging in 8 male PRO (21.9 years), 6 male PRE (11 years, Tanner 1–2) and 12 male non-active controls (6 adults: 23.5 years; and 6 prepubescents: 10.7 years, Tanner 1–2). PRO and PRE had 15 and 30% greater volume, respectively, in the dominant than in the contralateral PM (P?P?=?.34 in adults and 5%, P?=?.17 in children). The degree of side-to-side asymmetry in PM volume was greater in PRE than in PRO (P?相似文献

OBJECTIVE: The present study was designed to investigate dispositional empathy in high-risk parents for child physical abuse, using self-report instruments. More specifically, the objective was to know if high-risk parents for child physical abuse, in comparison with low-risk parents, show deficits on main dimensions of dispositional empathy: empathic concern, role-taking, and personal distress. METHOD: Based on their scores on the Abuse Scale of the CAP Inventory (Milner, 1986), 36 high-risk and 38 low-risk for child physical abuse participants were selected from a total sample of 440 Basque Country (Spain) general population parents. Both groups were statistically matched on sociodemographic variables. The Interpersonal Reactivity Index (IRI, Davis, 1980), the Hogan Empathy Scale (HES, Hogan, 1969) and the Questionnaire Measure of Emotional Empathy (QMEE, Mehrabian & Epstein, 1972) were used to assess dispositional empathy. RESULTS: As expected, high-risk, relative to low-risk, parents showed lower total scores on the HES and QMEE measures and lower scores on the IRI "Empathic concern" dimension. Moreover, high-risk, relative to low-risk, parents showed higher scores on the IRI "Personal distress" dimension. No differences between groups were observed for the IRI "Perspective-taking" dimension. CONCLUSIONS: Findings of the present study supported the hypothesis that high-risk parents for child physical abuse show a deficit in dispositional empathy. High-risk parents reported less feelings of warmth, compassion and concern for others and more feelings of anxiety and discomfort that result from observing another's negative experience. 相似文献
