This article examines the new-century business relevance of information literacy and why it is important for undergraduate business students. It then validates the relevance and value of the elements that make up the concept of information literacy with current business professionals (recruiters and employers). Business professionals were surveyed to reveal their (1) familiarity with the term information literacy, (2) feelings about the relevancy and value of information literacy in the business workplace, (3) perceived competency in information literacy of undergraduate business school graduates, (4) validation of cognitive difficulty elements of information literacy, and (5) reactions to other terms/phrases that more closely align with the concepts of information literacy in the business workplace. Although these business professionals were in general not familiar with the term, once they were informed of its components, they recognized and valued its processes.  相似文献

Problem-based learning has been applied over the last three decades to a diverse range of learning environments. In this educational approach, different problems are posed to the learners so that they can develop different solutions while learning about the problem domain. When applied to conceptual modelling, and particularly to Qualitative Reasoning, the solutions to problems are models that represent the behaviour of a dynamic system. The learner's task then is to bridge the gap between their initial model, as their first attempt to represent the system, and the target models that provide solutions to that problem. We propose the use of semantic technologies and resources to help in bridging that gap by providing links to terminology and formal definitions, and matching techniques to allow learners to benefit from existing models.  相似文献

This research content analyzed the news photographs of a major U.S. daily newspaper to examine the emotional portrayals of individuals in different gender, age, and ethnic subgroups. A multidimensional measure of emotion (pleasure, arousal, dominance) was used. A total of 1,595 individuals were coded. The results demonstrate that emotionality was stereotyped to some degree, particularly in relation to women, ethnic minorities, and senior citizens. Specifically, African Americans were depicted as excited whereas Asian Americans were seen as calm. Women were portrayed as happy and teens were shown as sad. The results support the social construction of emotion and suggest that the news media play a role in framing and constructing emotional meaning with regard to different subgroups in American society.  相似文献

Laser cleaning has been used to restore the soiled terracotta statues and decorations of the tympanum of the portal of Palos of the Cathedral of Seville in Spain. A simultaneous laboratory study performed on a representative sample helped to identify the optimum laser conditions to remove the dark soiling layer produced by air pollution. It was found that irradiation at 1064 nm with a Q-switched Nd:YAG laser was more effective than the harmonic wavelengths of 532 or 266 nm. LIBS and Raman microscopy gave information on the composition of terracotta and identified the presence of a protective layer made of gypsum and calcite. As detected by Raman spectroscopy, laser irradiation caused the elimination of the carbon component of the soiling layer and the appearance of an anhydrite component in the laser irradiated gypsum layer applied over the terracotta substrate for protective purposes. Local heating of the surface caused by laser irradiation at 1064 nm, the laser wavelength used for restoration of the portal, might be responsible for a process of partial dehydration of gypsum into anhydrite.  相似文献

Limited data are available on the female athlete triad (Triad) in athletes from minority groups. We explored subclinical and clinical Triad components amongst adolescent elite Kenyan athletes (n = 61) and non-athletes (n = 49). Participants completed demographic, health, sport and menstrual history questionnaires as well as a 5-day weighed dietary record and exercise log to calculate energy availability (EA). Ultrasound assessed calcaneus bone mineral density (BMD). Eating Disorder Inventory subscales and the Three-Factor Eating Questionnaire’s cognitive dietary restraint subscale measured disordered eating (DE). EA was lower in athletes than non-athletes (36.5 ± 4.5 vs. 39.5 ± 5.7 kcal ? kg FFM?1 ? d?1, P = 0.003). More athletes were identified with clinical low EA (17.9% vs. 2.2%, OR = 9.5, 95% CI 1.17–77, P = 0.021) and clinical menstrual dysfunction (32.7% vs. 18.3%, χ2 = 7.1, P = 0.02). Subclinical (75.4% vs. 71.4%) and clinical DE (4.9% vs. 10.2%, P = 0.56) as well as BMD were similar between athletes and non-athletes. More athletes had two Triad components than non-athletes (8.9% vs. 0%, OR = 0.6, 95% CI 0.5–6.9, P = 0.05). Kenyan adolescent participants presented with one or more subclinical and/or clinical Triad component. It is essential that athletes and their entourage be educated on their energy needs including health and performance consequences of an energy deficiency.  相似文献
