The Quality of Online and Offline Relationships: The Role of Multiplexity and Duration of Social Relationships     

Gustavo Mesch  Ilan Talmud 《The Information Society》2013,29(3):137-148

Recent studies have shown that adolescents use the Internet not only to maintain social relationships with distant relatives and friends but also to create new relationships online; some of these friendships become integrated into their social circle. Research has focused mainly on the effect of the Internet on existing relationships or the nature of online-only ties, so studies comparing the quality of online and face-to-face relationships are missing. The goal of this study is to bridge this gap. In keeping with previous studies on social association, we argue that the quality of social relationships is dependent on duration and diversity of topics and activities carried together. Time is important, as it facilitates the development of a collective shared history and identity. Intimacy develops through the participation in shared activities and discussion of diverse issues of personal concern. Using a representative sample of the adolescent population in Israel, we find that closeness to a friend is a function of social similarity, content and activity multiplexity, and duration of the relationships. Friendships originated in the Internet are perceived as less close and supportive because they are relatively new and online friends are involved in less joint activities and less topics of discussion. The implications of the findings are discussed.  相似文献   

The Relations of Parental Characteristics and Practices to Children''s Vicarious Emotional Responding   总被引：3，自引：0，他引：3  

Nancy Eisenberg  Richard A. Fabes  Mark Schaller  Gustavo Carlo  Paul A. Miller 《Child development》1991,62(6):1393-1408

We examined the relation of parental empathy-related characteristics and emotion-related child-rearing practices to third and sixth graders' vicarious emotional responding. Children's heart rate, skin conductance, facial, and self-reported reactions to a sympathy-inducing film were assessed, as were their dispositional sympathy, empathy, and self-monitoring. Parental sympathy was positively related to low levels of personal distress in same-sex children and, for both parents, with sons' dispositional sympathy or empathy. Parental emphasis on problem-focused coping strategies when their sons were anxious was positively correlated with indexes of sons' situational and dispositional sympathy. Same-sex parental restrictiveness in regard to the control of inappropriate, hurtful emotional displays was associated with sons' and daughters' dispositional and situational sympathy, whereas maternal restrictiveness in regard to emotions that are unlikely to hurt others was correlated with nonverbal indexes of personal distress and self reports of low distress. Parental emphasis on control of the child's own negative emotion was associated with children's self-monitoring.  相似文献

Near-infrared spectroscopy-derived total haemoglobin as an indicator of changes in muscle blood flow during exercise-induced hyperaemia     

Thiago Silveira Alvares  Gustavo Vieira de Oliveira  Rogério Soares  Juan Manuel Murias 《Journal of sports sciences》2020,38(7):751-758

ABSTRACT

Blood flow changes in response to exercise have been attributed, among other factors, to the effect of vasodilators factors on the microvasculature, suggesting a close relationship between small blood vessels and conducting arteries. The main purpose of this study was to determine the relationship between the changes in near infrared spectroscopy (NIRS)-derived total haemoglobin ([tHb]) and muscle oxygen saturation (SmO₂) signals and femoral artery blood flow in response to resistance exercise at fast- and slow-velocity muscle contraction. The study randomised crossover design included twelve participants. NIRS and blood flow measurements were continuously monitored before, during, and 5 min after the exercise protocol. There was a significant correlation between [tHb] reperfusion slope ([tHb]_slope) and peak blood flow (BF_peak) after slow- and fast-velocity muscle contraction (r = 0.83, p = 0.0008 and r = 0.72, p = 0.0080, respectively). No significant correlation existed between the SmO₂ reperfusion slope (SmO_{2_slope}) and BF_peak after both slow- and fast-velocity muscle contraction exercise (r = ?0.46, p = 0.1253 and r = 0.33, p = 0.2841, respectively). This study demonstrated a strong relationship between the NIRS-derived [tHb] and Doppler ultrasound BF during the recovery period of dynamic resistance exercise at both slow- and fast-velocity contraction.  相似文献

BUILDING A LEARNING EXPERIENCE: THE IMPLEMENTATION OF A CLERKSHIP IN GERIATRIC MEDICINE     

Gustavo Duque  Michael Bonnycastle  Najmi Nazerali  Robert Bailey  Catherine Ferrier  Paul Heilpern 《Educational gerontology》2013,39(8):671-683

Recent curriculum changes at McGill University include a mandatory 4-week clerkship for third-year medical students. The basis of this clerkship is the assessment and management of frail elderly who have a combination of complex acute and chronic medical problems and functional disabilities. It includes the understanding of the need for continuity of care across settings and the transition from hospital to the community. Our main purpose is to offer students a learning experience based upon self-reflection, access to technology, interactive learning and permanent feedback. To accomplish the technological goals, didactic sessions were mostly electronic-based with two main components: web-based interactive modules that include the contents in seven web-based interactive lectures complemented with pre- and post-tests, and an electronic portfolio to assess students' acquisition of skills and attitudes. We expect that implementation of this model of clinical clerkship will prepare future physicians, not only for the practice of geriatric medicine, but also for different medical and surgical specialties, and will enhance the attitudes, knowledge, and skills practitioners need to care for older people.  相似文献   

Packaging and unpackaging knowledge in mass higher education—a knowledge management perspective     

Gustavo Guzman  Luiz F. Trivelato 《Higher Education》2011,62(4):451-465

The progressive deployment of market-oriented regulatory frameworks in mass Higher Education Institutions (MHEI hereafter) triggered, in a wide variety of forms and degrees, the application of Knowledge Management principles in MHEI. This means the application of the knowledge ‘codification strategy’, where the focus is on the economies of the re-use of centrally developed knowledge through codifying, storing and distributing knowledge. This process however, presents significant challenges. Both knowledge and non-knowledge related aspects might constrain the application of knowledge codification strategies in MHEI. The aim of this paper is to better understand the application of knowledge codification strategies in MHEI, from a knowledge management perspective. This is done by examining the use of course outlines as the critical means to ‘transfer’ codified knowledge. The research site was a MHEI that explicitly followed a ‘codification strategy’, where the profits come from the economies of scale and low cost operation. Research findings point out mixed outcomes. The set of cost-saving managerial-oriented initiatives together with the deployment of knowledge codification strategies simultaneously supported the knowledge transfer of codified-oriented courses associated to low levels of tacit knowledge and constrained knowledge transfer of codified-oriented courses associated with slightly higher levels of tacit knowledge. This finding can be credited to a set of both knowledge and non-knowledge related issues. The implications for the management of knowledge in MHEI were explored.  相似文献

A Model of Maternal and Paternal Ethnic Socialization of Mexican‐American Adolescents’ Self‐Views          下载免费PDF全文

George P. Knight  Gustavo Carlo  Cara Streit  Rebecca M.B. White 《Child development》2017,88(6):1885-1896

Data from a sample of 462 Mexican‐American adolescents (M = 10.4 years, SD = .55; 48.1% girls), mothers, and fathers were used to test an ethnic socialization model of ethnic identity and self‐efficacy that also considered mainstream parenting styles (e.g., authoritative parenting). Findings supported the ethnic socialization model: parents’ endorsement of Mexican‐American values were associated with ethnic socialization at fifth grade and seventh grade; maternal ethnic socialization at fifth grade and paternal ethnic socialization at seventh grade were associated with adolescents’ ethnic identity exploration at 10th grade and, in turn, self‐efficacy at 12th grade. The findings support ethnic socialization conceptions of how self‐views of ethnicity develop from childhood across adolescence in Mexican‐American children.  相似文献
