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 ...

Enzyme Assays Using Earthworms for Assessing Innate and Nonspecific Immunotoxicity of Xenobiotics

Enzyme Assays Using Earthworms for Assessing Innate and Nonspecific Immunotoxicity of Xenobiotics

Date: May 1992
Creator: Chen, Shing-Chong
Description: Principal objectives of my research were to: (1) report for the first time that coelomocytes are able to reduce NBT dye and confirm the presence of lysozyme-like activity in earthworm; (2) develop a standard methodology for determination of NBT reduction and lysozyme-like activity in earthworms; (3) compare NBT reduction and lysozyme-like activity in earthworms with those of murine and human cells and fluids; and (4) demonstrate the sensitivity of earthworm NBT reduction and lysozyme-like activity as the assays using matrics in refuse-derived fuel fly ash (RDFF) and CuSO4.

The Eosinophil and Lysophospholipase Responses in Mice Infected with Trichinella spiralis: A Role for the Lymphocyte and Macrophage

The Eosinophil and Lysophospholipase Responses in Mice Infected with Trichinella spiralis: A Role for the Lymphocyte and Macrophage

Date: August 1986
Creator: Adewusi, Iyabode Olukemi, 1958-
Description: The relationship among eosinophils, lysophospholipase activity and the immune response in animals infected with Trichinella spiralis was studied using in vivo and in vitro techniques. In an in vivo experiment, anti-thymocyte serum (ATS) was administered to mice infected with T. spiralis and its effects on intestinal lysophospholipase (EC 3.1.1.5.) activity, peripheral blood, bone marrow and intestinal eosinophilia were measured in the same experimental animal. The ATS caused a significant temporally related suppression of both the tissue lysophospholipase response and eosinophilia, in all three compartments. These findings support the hypothesis that parasite-induced eosinophilia is the cause of the increased lysophospholipase activity of parasitized tissue and that the responses are thymus cell-dependent. In vitro experiments demonstrated that the eosinophil was the primary inflammatory cell source of lysophospholipase among eosinophils, neutrophils macrophages and lymphocytes. The role of other cells and antigen in the production of the enzyme by the eosinophil was also investigated in vitro• Results demonstrated that eosinophils cultured with both T. spiralis antigen and other leukocytes yielded enzyme activities significantly greater than eosinophils cultured alone or with only antigen. More specific experiments showed that T-lymphocytes were the cells responsible for influencing the eosinophils' lysophospholipase activity in the presence of antigen, and ...

The Eosinophil Response in Mice Infected with Trichinella spiralis or Trichinella pseudospiralis as Indicated by Phospholipase B Activity

The Eosinophil Response in Mice Infected with Trichinella spiralis or Trichinella pseudospiralis as Indicated by Phospholipase B Activity

Date: December 1992
Creator: Hsu, Shing-Chien
Description: The host eosinophil response was compared in mice infected with either T. spiralis or T. pseudospiralis by determination of levels of splenic and intestinal phospholipase B, a marker enzyme for eosinophils. Primary infection of naive mice and challenge infection of homologously sensitized mice with T. pseudospiralis resulted in significantly lower tissue phospholipase B activities than infection with T. spiralis. Mice homologously challenged with T. pseudospiralis did exhibit an anamnestic eosinophil response compared to mice given a primary T. pseudospiralis infection. This anamnestic response, however, was significantly lower than the eosinophil response seen in sensitized mice given a homologous T. spiralis challenge. Mice sensitized to T. spiralis or T. pseudospiralis and heterologous challenge demonstrated an elevated eosinophil response compared to mice given a primary infection with either parasite. The heterologous challenge response, however, was not as intense as found for sensitized mice given a homologous challenge.

The Epic Element in Hiawatha

The Epic Element in Hiawatha

Date: August 1953
Creator: Bass, Mary Laura
Description: By tracing the development of the epic, oral and written, as in Chapter III, the qualities that are characteristic of the epic and the devices associated with the epic through continued usage were found to be the constant factors upon which the definition of the epic is formulated. The application to Hiawatha of the epic definition in terms of form, theme, subject matter, characters, tone, the use of the supernatural, and the use of characteristic devices, strengthens the thesis that Longfellow has written an epic.

Epic Qualities in Moby-Dick

Epic Qualities in Moby-Dick

Date: August 1952
Creator: Russell, John Joe
Description: Many critics not satisfied with explaining Moby-Dick in terms of the novel, have sough analogies in other literary genres. Most often parallels have been drawn from epic and dramatic literature. Critics have called Moby-Dick either an epic or a tragedy. After examining the evidence presented by both schools of thought, after establishing a workable definition of the epic and listing the most common epic devices, and after examining Moby-Dick in terms of this definition and discovering many of the epic devices in it, I propose the thesis that Melville has written an epic, not unlike the great epics of the past.
