Objectives
This study assessed the need to develop a public health informatics (PHI) introductory course and determine contents of such a course.Methods
Community assessments employing focus group interviews and an online survey were utilized to determine course need and content.Results
Results revealed a need to provide PHI training to graduate public health students and suggested broad course content requirements. Results indicated lack of awareness of libraries and librarians as sources of public health information.Conclusions
A graduate PHI course was developed and delivered. Additionally, implementation of a subject guide increased the library''s profile. 相似文献222.

Education is in need of reform, and the development of the sciences of mind and brain are candidates to contribute to the renovation of the way people are instructed and of the tools that mediate learning. Knowledge‐ and evidence‐based approaches to education put forward the fact that educational systems are inadequate to provide an answer to the challenges of the 21st century and claim that education should be guided by scientific principles rather than by intuition and professional wisdom only (or, worst, by tradition). This is because sciences that are capable of shedding light into learning process have dramatically advanced during the last half‐century and, still more meaningfully, during the last 20 years. The time has come for a new science of learning to rise, which is structured around cognitive and neuroscience, investigates topics that stem from educational problems, and rests on rigorous forms of in‐laboratory and in‐vivo evaluation. 相似文献

Recent research has appropriately emphasized the significant role played by feature films in the creation (as well as the reflection) of popular stereotypes of the scientist. However, no particular study has yet been devoted to the depiction of women scientists in the cinema, even though it is quite clear that this presents its own distinctive features. Taking the influential Madame Curie (Mervyn LeRoy, 1943) as a starting point, this paper attempts to give a first overview of the subject. 相似文献

This study investigated how manipulating first step width affects 3D external force production, centre of mass (CoM) motion and performance in athletic sprinting. Eight male and 2 female competitive sprinters (100m PB: 11.03 ± 0.36 s male and 11.6 ± 0.45 s female) performed 10 maximal effort block starts. External force and three-dimensional kinematics were recorded in both the block and first stance phases. Five trials were performed with the athletes performing their preferred technique (Skating) and five trials with the athletes running inside a 0.3 m lane (Narrow). By reducing step width from a mean of 0.31 ± 0.06 m (Skating) to 0.19 ± 0.03 m (Narrow), reductions were found between the two styles in medial block and medial 1st stance impulses, 1st stance anterior toe-off velocity and mediolateral motion of the CoM. No differences were found in block time, step length, stance time, average net resultant force vector, net anteroposterior impulse nor normalised external power. Step width correlated positively with medial impulse but not with braking nor net anteroposterior impulse. Despite less medially directed forces and less mediolateral motion of the CoM in the Narrow trials, no immediate improvement to performance was found by restricting step width. 相似文献

The aim of this study was to compare the effects of two different intensity distribution training programmes (polarized (POL) and threshold (THR)) on aerobic performance, strength and body composition variables in ultra-endurance runners. Twenty recreationally trained athletes were allocated to POL (n?=?11; age: 40.6?±?9.7 years; height: 175.4?±?7?cm; weight: 73.5?±?10.8?kg; fat mass 18.4?±?6.0%; VO2max: 55.8?±?4.9?ml/kg/min) or THR group (n?=?9; age: 36.8?±?9.2 years; height: 178.5?±?4.2?cm; weight: 75.5?±?10.4?kg; fat mass 14.9?±?5.3%; VO2max: 57.1?±?5.2?ml/kg/min) and performed the 12 weeks training programme. Both programmes had similar total time and load but a different intensity distribution (POL?=?79.8?±?2.1% in Zone 1; 3.9?±?1.9% in Zone 2; 16.4?±?1.5% in Zone 3; THR?=?67.2?±?4.6% in Zone 1; 33.8?±?4.6% in Zone 2; 0% in Zone 3). Body composition, isokinetic strength and aerobic running performance were measured before and after each programme. Both groups decreased fat mass after training (POL= Δ–11.2%; p?=?.017; ES?=?0.32; THR= Δ–18.8%; p?.01; ES?=?0.48). Also, POL group improved running economy at 10?km/h (Δ–5.4%; p?=?0.003; ES?=?0.71) and 12?km/h (Δ–4.5%; p?=?.026; ES?=?0.73) and running time to exhaustion (Δ2.4%; p?=?.011; ES?=?0.33). No changes were observed in strength and no significant differences were observed between the group in any variable. Compared with THR distribution, 12 weeks of POL training efficiently improves aerobic performance in recreational ultra-endurance runners. 相似文献

We analyze art pricing in a unique dataset on Madrid inventories between 1600 and 1750. We estimate a price index for the Spanish art market that is used for a general historical analysis of art during this period, showing a large increase in the real price of paintings during the XVII century. Then we examine the price differential between domestic and foreign paintings: At the beginning of the century domestic production was priced substantially below imported paintings, but the price gap was gradually reduced during the century. We argue that such a price convergence was not the fruit of variations in real exchange rate, relative supply or home bias, but was associated with increasing prices for the new domestic painters of the XVII century. Increasing remuneration for painting may have induced artistic innovations by domestic producers and created the conditions for the development of the Siglo de Oro of Spanish art. 相似文献

In recent years the methodology of engineering education has been changing and many projects deal with improving the educational software. This paper reports on the virtual laboratory, a virtual environment applied to experimental analysis. The goals of the virtual laboratory are to introduce the laboratory environment to the student entering this world, so different from the typical theoretical lectures, for the first time, and to overcome the above-mentioned drawbacks. It should be mentioned that the virtual laboratory is not meant to replace highly enriching, practical experience, but rather is meant to train the individual, in order to improve his/her performance in later actual practice. The virtual laboratory experience starts with the study of strain measurements, an engineering technique widely used to measure deformations, strains, mechanical properties of materials and other variables which are used to analyse many problems.The strain measurement virtual laboratory is meant to offer the possibility of simulating experiences, undergone in a real laboratory, through the Internet. The student is expected to familiarize him/herself with the techniques, procedures, devices and theories in the laboratory environment. 相似文献

We introduce in this article the construct of theme-park psychology which we define as psychological theory and research drawn only from limited and unrepresentative samples of participants, tasks and situational contexts within the context of worldwide populations. Results obtained from limited populations, tasks, and situational contexts often are inappropriately generalized and then used as a basis for educational policy. In theme-park psychology, easy-to-study populations, tasks, and situational contexts repeatedly may show the same patterns in data, leading to tantalizing generalizations that are nevertheless wrong. We describe studies by ourselves and by others with respect to human intelligence that illustrate our views and that cast doubt on traditional notions. 相似文献
