Me, My Selfie, and I| Personality Traits' Influence on Online Self-Portrait Sharing

Vardeman, Christopher E. 29 November 2017 (has links)
<p> Millions of selfies are posted on social media every day. Past research has attempted to explain this behavior, though inconsistent results have necessitated further investigation. The present study broadened the scope of selfie research by using electronic survey methods in a sample of active social media users to examine the relationships between narcissism, extraversion, purpose in life, prevalence of posting, and two novel constructs: number of selfie drafts taken before final selection, and immediacy of posting after taking a selfie. Higher prevalence was significantly related to greater number of drafts and belief that selfies facilitate self-expression and self-discovery. Greater number of drafts was also associated with lower feelings of purpose, greater immediacy, and younger age. These findings, together with an absence of strong links between selfies and narcissism or extraversion, suggest that selfie sharing is more nuanced than previous studies have shown. The present data&rsquo;s correlational nature precludes causal inference, but informs future research on selfies and human behavior on social media.</p><p>

Institutional ideology and industry-level action: A macro analysis of corporate legitimation in the United States petroleum industry

Prasad, Anshuman 01 January 1994 (has links)
This dissertation is a multi-method, institutional theoretic study that sought to understand how organizational communication in the United States petroleum industry functioned as a device for corporate legitimation over the years 1975-1990. The study investigated the symbolic dimension of organizational communication taking place via the medium of oil industry Annual Reports. The study addressed two major research questions: (i) What was the nature of corporate legitimation in the U.S. petroleum industry during the years 1975-1990? and (ii) What was the structure of corporate legitimation in the industry over these years? The context for these questions was provided by important industry-level actions such as business-government relations, diversification, OPEC relations, corporate restructuring, etc. To understand the nature of corporate legitimation, the study employed methods of grounded theory analysis. In addition to investigating the ideological characteristics of oil industry Chief Executive Officers' (CEOs') Letters to Shareholders, this analysis also focussed upon the linguistic devices of persuasion (e.g., myths, metaphors, etc.) and the processes of discursive closure employed in these letters. On the other hand, quantitative techniques of content analysis, including multivariate research methods such as factor analysis, discriminant analysis and MANOVAs, were employed for analyzing the structure of corporate legitimation. These analyses were designed to investigate the interrelationship of the various concepts by which oil industry CEOs expressed themselves in their Annual Reports. This study show that the U.S. oil industry employed eight inter-connected ideologies in the process of legitimating salient industry-level actions of these years. In part, the persuasive power of these ideologies derived from their ability to evoke certain mythic and taken-for-granted elements of the cultural 'common sense.' As regards the structure of corporate legitimation, an important finding of the study is that the industry's Annual Reports assumed four personae in the process of articulating their ideological messages. The study advances the thesis that corporate legitimation in an industry such as petroleum implies the legitimation of a given 'way of life,' and involves both expressing and constituting the subjectivities upon which this way of life depends. Finally, the study draws some implications for management research and practice.

The silent majority: An examination of nonresponse in college student surveys

Kolek, Ethan A 01 January 2012 (has links)
Nonresponse is a growing problem in surveys of college students and the general population. At present, we have a limited understanding of survey nonresponse in college student populations and therefore the extent to which survey results may be biased. The purpose of this dissertation is to explore three facets of nonresponse in surveys of college students in order to strengthen our empirical and conceptual understanding of this phenomenon. This dissertation seeks to contribute to our understanding of who participates in surveys and who does not, how students experience the process of being asked to complete surveys, and whether or not students’ perspectives about surveys suggest that college student surveys should be conceptualized as organizational surveys. To begin to answer these questions, I conducted three studies—a secondary data analysis that examines student characteristics associated with the odds of completing a survey, a “survey on surveys” study that asks students about their experiences with surveys, and a series of focus groups to understand how students made sense of surveys at their institutions. Taken together, these findings provide a basis for a more developed and nuanced understanding of nonresponse in student surveys.

When to worry more: An empirical investigation of the effects of non-randomly missing data on regression analysis

Sellers, Deborah Ellen 01 January 1992 (has links)
Statistical remedies exist for most configurations of missing data, but these remedies require specific models and/or measures of nonresponse that are usually unavailable to the researcher. Consequently, the question of the conditions under which the threat to regression analysis posed by non-randomly missing data increases becomes relevant. This simulation study addresses that question empirically by assessing the effect of various configurations of non-randomly missing data on OLS regression analysis completed with different techniques for coping with the missing observations on samples drawn from varying populations. The configurations of missing data vary by which variable has missing observations, which variable drives the response mechanism, and the strength of the response mechanism. Five different techniques--listwise deletion, pairwise deletion, regression estimation without the addition of a residual, regression estimation with the addition of a residual, and EM estimation--for coping with the missing observations are compared. The regression analysis is completed on samples of different sizes drawn from populations that vary on the degree of correlation between the independent variables and the effect sizes. The effects of the non-randomly missing observations are assessed in terms of the deviation of the estimated coefficient from its true value and the increase or decrease in the associated standard error relative to its value based on known population parameters. The effect of the missing observations on inference is examined as well. In general, when the strength of the missing data mechanism is low, all techniques except pairwise deletion perform quite well. When the strength of the missing data mechanism is high, regression with the addition of a residual and EM estimation perform better than the other techniques. Pairwise deletion and regression without the addition of a residual consistently produce the worst results. Finally, the most troublesome situation occurs when the chances of observing a variable depend upon the value of the variable itself.

Central America Asylum Seekers’ Health, Self-Sufficiency, and Integration Outcomes During the Asylum Claim Process Phase in Phoenix, Arizona

January 2020 (has links)
abstract: The purpose of this study is threefold: highlight the present health, self-sufficiency and integration needs and assets of asylum seekers in Phoenix, Arizona during the asylum seeking process phase (while an asylum claim is awaiting a decision); understand the City of Phoenix’s response to asylum seekers; and contextualize and compare the city’s present response to increased arrivals of asylum seekers against municipal responses in other contexts and academic discussions of the “local turn.”. Through semi-structured in-depth interviews with asylum seekers and community leaders, this study finds that asylum seekers’ physiological healthcare needs are sometimes met through emergency department admissions and referrals to sliding scale services by caseworkers in the International Rescue Committee’s Asylum-Seeking Families program in Phoenix. Mental and behavioral health service needs are less likely to be met, especially for women who want to speak with a medical professional about their traumatic experiences in Central America, trip through Mexico, detention in the United States (U.S.) and their often-marginalized lives in the U.S. This dissertation concomitantly explores how other municipalities in the U.S. and internationally have responded to increased immigration of asylum seekers and refugees to urban centers, and how certain approaches could be adopted in the City of Phoenix to better serve asylum seekers. / Dissertation/Thesis / Doctoral Dissertation Transborder Studies 2020

EXPLORATION OF FACTORS AFFECTING REPRESENTATION OF MINORITIES IN DERMATOLOGY

Rosenberg, Joshua Miles January 2023 (has links)
This paper examines the reasons underlying the underrepresentation of minority students in the field of dermatology. There continues to be both unconscious and implicit bias against African-American and Hispanic students in regard to dermatology residency. This demographic of students is generally dissuaded from pursuing this specialty for reasons that are enumerated in this piece of work. Incorporating evidence from governmental data, articles, journals, and opinions of leaders within the field of dermatology this paper will demonstrate that there is indeed a form of institutional racism that permeates this field of medicine particularly. The paper will proceed to explore potential solutions to these issues in the hope that the field will become more accessible to minority students in the future. / Urban Bioethics

At arm's length?: Commercial research agendas, academic science, and the construction of organizational boundaries

Cavanaugh, John Michael 01 January 1992 (has links)
Concepts of organizational boundary have played a long and integral role configuring the intellectual landscape of organizational theory. By and large, organizational-environmental frontiers are simply assumed to be there. The interpenetrated condition of contemporary organizations and environments, however, bids us to question theorizing which treats organizations and environments as ontologically distinct entities. In particular, a new generation of research alliances between a host of American research universities and multi-national corporations has provoked debate over the boundaries demarking university and industrial interests. Some (Traditionalists) fear that the separation between academic and commercial practices is breaking down, particularly as the commercial potential and shrinking developmental timeframes in some laboratory-driven fields place a premium on market-oriented research, entrepreneurship and exclusive claims to information ownership. Others (Instrumentalists) counter that the academy needs to update its internal system of values and priorities if universities are to effectively meet the needs of a contemporary knowledge-based society. Accordingly, this exploratory study attempts to address the substantivity of organizational boundary by examining how those who presumably construct frontiers--in this case select groups of university faculty--define the normative boundaries of their academic work. Using the oppositional modes characterizing the Traditionalist/Instrumentalist discourse as conceptual brick and mortar, faculty were invited to construct the social relationships of their professional work. Thirty-one (31) faculty members Q sorted 66 issue statements in a study designed to give numerical form to their normative boundaries, in order to test (1) the ontological status of organizational boundaries and (2) the claims of the Traditionalist-Instrumentalist antithesis. The indeterminacy of borders empirically elaborated in this study opens the literature's core territorial assumptions to interpretation. If, in other words, the "thingness" (Weick, 1977) of borders can no longer be sustained unproblematically, how is the Archimedian point of the management science universe--the single-minded, factual "organization"--to be located? Without firm boundaries, "insides" and "outsides" are no longer knowable. The ambiguity surrounding "the university's" location prompts a reconsideration of interpretive grammar that promotes organizations as sovereign and unified "centre(s) of calculation and classification" (Clegg, 1990).

Regulatory effects on the ecology of organizational mortality of home health agencies in Massachusetts

Rarig, Alice Jane 01 January 1993 (has links)
Changes in the regulatory environment and in resource availability are thought to have had differential impact on home health agencies of different types over the period since Medicare and Medicaid were implemented in 1966. This study uses survival analysis methods including the proportional hazards model to examine an administrative data base of annual survey data for 199 agencies that reported to the Massachusetts Department of Public Health between 1975 and 1986 to examine the following: (1) to see if the major regulatory change imposing the Medicare uniform cost report on all home health agencies resulted in greater hazard rates in the period 1977-1980, (2) to see if organizational mortality rates were higher for public agencies than for free-standing non-profit agencies, and (3) to see if organizational characteristics such as size and scope of services, or locational characteristics such as rurality or poverty level accounted for differences. Results indicate that hazard of failure is inversely proportional to size, and that when size and other variables are controlled, the crude differences in the failure rates of public and non-profit agencies are greatly reduced. Data on proprietary and hospital-based agencies were insufficient for comparative analysis. Hazard ratios indicated that small agencies faced hazard of failure about three times that of larger agencies, controlling for other variables. Failure rates increased in the four year period between passage and actual implementation of the uniform cost report requirement. However, time dependence of the hazard rates appeared insufficient to require inclusion in the modelling process. The period of observation was too short and the population of agencies too small to assess the mortality rate impact of resource constraints in the middle 1980s. Empirical evidence was consistent with the hypotheses that small agencies were at risk during the period when regulatory changes imposed a major administrative requirement and constrained reimbursement options. Rural location, broader scope of services and more specialists had protective effects on agencies. Hypothesized protective effects of variables thought to be associated with community support were found to be of borderline significance, but these possible associations require further study. The proportional hazard regression method provided a useful tool for analyzing an administrative data base with time series data on health care organizations.
