Environmental journalism curriculum as an imperative of democracy: A philosophical exploration.

Environmental journalism curriculum as an imperative of democracy: A philosophical exploration.

Date: August 2007
Creator: Loftis, Randy Lee
Description: Economic retrenchment, social shifts, and technological changes endanger journalism's democratic role. Journalism education faces parallel threats. I review the state of journalism and education, linking the crisis to society's loss of story, framed philosophically by the Dewey-critical theory split over journalism and power. I explore the potential for renewing journalism and education with Carey's ritual model and Postman's restoration of storytelling. I then summarize existing major academic programs and suggest a new interdisciplinary curriculum for environmental journalism, a specialty well suited to experimental, democracy-centered education. The curriculum uses as pedagogy active and conversational learning and reflection. A graduate introductory course is detailed, followed by additional suggested classes that could form the basis of a graduate certificate program or, with further expansion, a graduate degree concentration.

An environmental justice assessment of the light rail expansion in Denton County, Texas.

An environmental justice assessment of the light rail expansion in Denton County, Texas.

Date: August 2007
Creator: Moynihan, Colleen T.
Description: This study analyzes the proposed passenger rail line expansion along US Interstate Highway 35 in Denton County, Texas. A multi-dimensional approach was used to investigate potential environmental justice (EJ) consequences from the expansion of the transportation corridor. This study used empirical and historical evidence to identify and prioritize sites for potential EJ concerns. Citizen participation in the decision making process was also evaluated. The findings of this research suggest that the southeast Denton community has the highest potential for environmental justice concerns. This study concludes by offering suggestions for an effective public participation process. These include the incorporation of a community's local history into an environmental justice assessment, and tailoring the public planning process to the demographics and culture of the residents.

Environmental Modulation of the Onset of Air-breathing of the Siamese Fighting Fish and the Blue Gourami

Environmental Modulation of the Onset of Air-breathing of the Siamese Fighting Fish and the Blue Gourami

Access: Use of this item is restricted to the UNT Community.
Date: December 2015
Creator: Mendez Sanchez, Jose Fernando
Description: This study determined the effect of hypoxia on air-breathing onset and physiological and morphological characters in larvae of the air breathing fishes Trichopodus trichopterus and Betta splendens. Larvae were exposed intermittently (12/12 h daily) to 20, 17, and 14 kPa of PO2 from 1 to 40 days post-fertilization. Survival, onset of air breathing, wet body mass, O2, Pcrit were measured every 5 dpf. Hypoxia advanced by 4 days, and delayed by 9 days, the onset of air breathing in Betta and Trichopodus, respectively. Hypoxia increased larval body length, wet mass, and labyrinth organ respiratory surface of Betta, but did not affect these factors in Trichopodus. Hypoxic exposure increased O2 by 50-100% at each day throughout larval development in Betta, but had no effect on larval Trichopodus. Hypoxia decreased Pcrit in Betta by 37%, but increased Pcrit in Trichopodus by 70%. Larval Betta reared in hypoxia showed a modified heart rate:opercular rate ratio (3:1 to 2:1), but these changes did not occur in Trichopodus. Compared to Betta, the blood of Trichopodus had a higher P50 and much smaller Bohr and Root effects. These interspecific differences are likely due to ecophysiological differences: Betta is a non- obligatory air-breather after 36 dpf with ...

Environmental Philosophy and the Ethics of Terraforming Mars: Adding the Voices of Environmental Justice and Ecofeminism to the Ongoing Debate

Environmental Philosophy and the Ethics of Terraforming Mars: Adding the Voices of Environmental Justice and Ecofeminism to the Ongoing Debate

Date: August 2013
Creator: French, Robert Heath
Description: Questions concerning the ethics of terraforming Mars have received some attention from both philosophers and scientists during recent decades. A variety of theoretical approaches have been supplied by a number of authors, however research pursuant to this thesis has indicated at least two major blindspots in the published literature on the topic. First, a broad category of human considerations involving risks, dangers, and social, political, and economic inequalities that would likely be associated with efforts to terraform Mars have been woefully overlooked in the published literature to date. I attempt to rectify that oversight by employing the interpretive lens of environmental justice to address questions of environmental colonialism, equality in terms of political participation and inclusion in decision making structures, risks associated with technological progressivism, and responses to anthropogenic climate change. Only by including the historically marginalized and politically disenfranchised "voices," of both humans and nonhumans, can any future plan to terraform Mars be deemed ethical, moral or just according to the framework provided by environmental justice. Furthermore, broader political inclusion of this sort conforms to what ecofeminist author Val Plumwood calls the "intentional recognition stance" and provides an avenue through which globally societies can include nonanthropocentric considerations in decision ...

Environmental Scanning Behavior in Physical Therapy Private Practice Firms: its Relationship to the Level of Entrepreneurship and Legal Regulatory Environment

Environmental Scanning Behavior in Physical Therapy Private Practice Firms: its Relationship to the Level of Entrepreneurship and Legal Regulatory Environment

Date: August 1988
Creator: Schafer, D. Sue
Description: This study examined the effects of entrepreneurship level and legal regulatory environment on environmental scanning in one component of the health services industry, private practice physical therapy. Two aspects of scanning served as dependent variables: (1) extent to which firms scrutinized six environmental sectors (competitor, customer, technological, regulatory, economic, social-political) and (2) frequency of information source use (human vs. written). Availability of information was a covariate for frequency of source use. Three levels of entrepreneurship were determined by scores on the Covin and Slevin (1986) entrepreneurship scale. Firms were placed in one of three legal regulatory categories according to the state in which the firm delivered services. A structured questionnaire was sent to 450 randomly selected members of the American Physical Therapy Association's Private Practice Section. Respondents were major decision makers, e.g., owners, chief executive officers. The sample was stratified according to three types of regulatory environment. A response rate of 75% was achieved (n = 318) with equal representation from each stratum. All questionnaire subscales exhibited high internal reliability and validity. The study used a 3x3 factorial design to analyze the data. Two multivariate analyses were conducted, one for each dependent variable set. Results indicated that "high" entrepreneurial level ...

Environmental Scanning Practices of Manufacturing Firms in Nigeria

Environmental Scanning Practices of Manufacturing Firms in Nigeria

Date: May 1992
Creator: Sawyerr, Olukemi Olaitan
Description: The purpose of this study was to examine scanning practices in a developing country by looking at the scanning behavior of executives of Nigerian manufacturing firms. Specifically, this study examined the decision maker's perception of environmental uncertainty (PEU), the frequency and degree of interest with which decision makers scan each sector of the environment, the frequency of use of various sources of information, the number of organizational adjustments made in response to actions of environmental groups, and the obstacles encountered in collecting information from the environment.

Environmental Virtue Education: Ancient Wisdom Applied

Environmental Virtue Education: Ancient Wisdom Applied

Date: August 2005
Creator: Lindemann, Monica A.
Description: The focus of environmental philosophy has thus far heavily depended on the extension of rights to nonhuman nature. Due to inherent difficulties with this approach to environmental problems, I propose a shift from the contemporary language of rights and duties to the concept of character development. I claim that a theory of environmental virtue ethics can circumvent many of the difficulties arising from the language of rights, duties, and moral claims by emphasizing the cultivation of certain dispositions in the individual moral agent. In this thesis, I examine the advantages of virtue ethics over deontological and utilitarian theories to show the potential of developing an ecological virtue ethic. I provide a preliminary list of ecological virtues by drawing on Aristotle's account of traditional virtues as well as on contemporary formulations of environmental virtues. Then, I propose that certain types of rules (rules of thumb) are valuable for the cultivation of environmental virtues, since they affect the way the moral agent perceives a particular situation. Lastly, I offer preliminary formulations of these rules of thumb.

Environmentally-friendly purchase intentions: Debunking the misconception behind apathetic consumer attitudes.

Environmentally-friendly purchase intentions: Debunking the misconception behind apathetic consumer attitudes.

Date: December 2008
Creator: Umberson, Kirsten
Description: By measuring intentions to purchase, this research gives insight into environmental attitudes, pressures to purchase environmentally friendly apparel, factors that inhibit environmentally friendly apparel purchasing, awareness of environmentally friendly apparel purchase options, and marketing insight into the eco-friendly consumer. The theory of planned behavior (TPB) was used to assess consumer purchasing intentions for environmentally friendly apparel. The TPB consists of a three-pronged measurement: individual attitudes, subjective norms, and perceived behavioral control. Individual attitudes were gauged on three dimensions which included environmental attitudes, demographic patterns, and environmentally friendly apparel purchase intentions. Subjective norms involve social pressure to engage in eco-friendly behavior, perceived individual environmental impact, and desire for uniqueness in dress. Finally, perceived behavioral control was studied through previous environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel. The results revealed that individual environmental attitudes, social pressure to behave environmentally friendly, perceived individual environmental impact, desire for uniqueness in dress, past environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel all have an impact on intentions to purchase environmentally friendly apparel. The variable with the strongest relationship to intentions was social pressure. A demographic profile ...
