Making biodiversity meaningful through environmental education     

Daan Van Weelie  Arjen Wals 《International Journal of Science Education》2013,35(11):1143-1156

Biodiversity is an emerging theme in science, society and, more recently, education. There is no one single definition of biodiversity that is adequate in all situations. Both the knowledge base and the value base of biodiversity are variable and questionable. Because of these characteristics, biodiversity makes for an interesting vehicle for linking science and society, and the investigation of the normative underpinnings of 'science-in-the making'. Based on a 3-year study, this paper explores the crossroads between science education and environmental education and presents a framework for tapping the environmental education potential of biodiversity. Outlined are a number stepping stones for making biodiversity meaningful to learners. It is argued that, from the perspective of environmental education, the illdefined nature of biodiversity is a useful feature. Biodiversity is renewing the discourse on nature conservation issues by bringing together different groups in society that are searching for a common language to discuss nature conservation issues in relation to sustainability issues. The resulting debate allows the socio-scientific dispute character of 'science-in-the-making' to surface. Participation in such a dispute is an excellent opportunity to learn about a highly relevant, controversial, emotionally charged and debatable topic at the crossroads of science, technology and society  相似文献   

The effect of submaximal exercise on recovery hemodynamics and thermoregulation in men and women     

Fisher M  Paolone V  Rosene J  Drury D  Van Dyke A  Moroney D 《Research quarterly for exercise and sport》1999,70(4):361-368

Five women and 5 men were studied to examine the effects of submaximal exercise on thermoregulatory and hemodynamic variables during recovery in two environments: (a) control (C), 22 degrees C, 33% rh; and (b) hot humid (H), 32 degrees C. The participants exercised on a cycle ergometer at 60% of peak oxygen consumption for 35 min prior to 90 min of seated recovery. Sessions were identical, except for environment. Variables evaluated (p < .05) were: core temperature (TR), mean skin temperature (Ts), sweat rate (SR), heart rate (HR), stroke index (SI), cardiac index (CI), forearm blood flow (FBF), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Men and women exhibited similar patterns of TR, Ts, and SR in both environments. Ts and SR (collapsed means for gender) were higher in the H than in the C. DBP was higher in men than in women throughout recovery in both environments. With combined means for gender, HR was higher in the H than in the C. CI, SI, FBF, and SBP were similar in both environments and returned to baseline within 15 min into recovery. These data suggest that heat dissipation during extended recovery was accomplished with similar contributions of cutaneous vasodilation and sweating in M and F. Furthermore, the moderate exercise level did not influence hemodynamics beyond 15 min of recovery in either environment.  相似文献   

GaIN (Georgia Interactive Network for Medical Information) study on health professionals' search requests and continuing education needs     

LaBeause J  Van de Water N  Carey P  Fielder M  Sorrow B  Woolbright C 《Medical reference services quarterly》1999,18(2):81-89

Health sciences librarians are being called upon to be more proactive in their institutions' continuing education efforts. In an effort to identify whether search requests indicated CE needs, a study was conducted by a group of members of GaIN (Georgia Interactive Network for Medical Information). MEDLINE requests from health care professionals for subject specific clinical topics were collected during a six-month period via a standard search request form created for the study. Copies of all completed requests were collected and broad ICD-9 codes assigned to the search topics. Institutional reports were generated for each participating library to share with hospital CE coordinators. They were also compiled for the group as a whole, and reflected the "hottest" topics requested during the study period for physicians and for non-physicians (nurses, allied health, administrators). A survey to hospital librarians and CE educators showed some value in the reports, but greater potential for further collaboration between librarians and CE coordinators.  相似文献

Convergence: An investment perspective     

Leo Kivijarv Ph.D. 《Publishing Research Quarterly》2002,18(2):12-22

Conclusion  Convergence is a very exciting model and one that holds, unforeseen opportunities. However in the current economic environment, the investment community is hesitant to recommend that communications companies devote many resources in that area. The convergence mode must prove that it can generate revenue and profits. Yet, it is limited to an advertising-supported model—a part of the communications industry that has struggled during the past, year due to the recession. The increased advertising revenue that would be generated by the convergence model is tainted—most likely taking advertising share away from the traditional media segments that are supporting the model. Tied to the convergence model is a high dependency on the Internet. Internet advertising is not local. In addition, financial data clearly illustrates that the Internet has caused profit margins to decrease substantially, something that the traditional media company supporting the convergence model can not allow to happen. Finally, FCC deregulation with regards to television station cap restrictions, cable system operators owning broadcasters in the same market, and cross ownership of newspapers and television stations in the same market, will most likely have a negative impact on the convergence model. If a communications company should decide to go forward with convergence, there are five rules that should be followed:

1.	Use personnel and technology efficiently
2.	Extend brand awareness of pre-existing communications products
3.	Offer cross-media advertising packages
4.	Return users to traditional media outlets
5.	BE PROFITABLE QUICKLY!39.

The essay is based on a presentation made by Dr. Kivijarv at convergece: The Tour, a four-day conference sponsored by The American Press Institute. The purpose of the conference is to analyze the various issues that communications companies should consider before attempting to build multimedia news operations that consolidate newspaper, television, wired cable, and/or Internet divisions in a specific market. Dr. Kivijarv's presentation occurred on the final day of the conference and spoke to the investment community's financial concerns. Veronis Suhler Stevenson publishes, two of the leading annual reports on the communications industry—the Communications Industry Forecast and the Communications Industry Report. A majority of the data used in the presentation and this essay come from those reports and Dr. Kivijarv, as the Director of Research & Publications at Veronis Suhler Stevenson, serves as the editor of the two reports.  相似文献   

Do you Mini-Med School? Leveraging library resources to improve Internet consumer health information literacy     

Van Moorsel G 《Medical reference services quarterly》2001,20(4):27-37

Popular for engaging public interest in medical science while promoting health awareness, Mini-Med School (MMS) programs also afford important if largely unrealized opportunities to improve the health information literacy of attendees. With a growing population using the Internet to make health decisions, needed venues for improving Internet Consumer Health Information (CHI) literacy may be found in the MMS platform. Surveyed directors of MMS programs understand the need to include CHI, and successful programs at SUNY Stony Brook and elsewhere demonstrate the potential for collaboration with affiliated health sciences libraries to integrate CHI instruction into MMS curricula.  相似文献

服务业创新的新熊彼特定义：基于新分类法的概念探讨     

Meindert Flikkema Paul Jansen Lidewey Van Der Sluis 《中国青年科技》2007,(11):F0003-F0003

创新是一项复杂的过程并具有多面性。在众多以创新与生产率之间联系为主题的研究中，由于数据限制，往往只采用单一指标来测度创新。本文对这种方式提出了质疑，认为这种研究方法可能会系统地偏向于某类经常通过参与创新活动以达到各种商业目的的公司或产业。为了更好地测度创新，本文介绍了一种创新索引，即以潜变量模型为基础的含有多项创新指标的线性指标组合。这一尝试得到加拿大制造业公司的大量微观数据组合的支持。  相似文献
