Associations between energy drink consumption and dietary behaviors among emerging adults

Poulos, Natalie Shepherd 11 November 2013 (has links)
The energy drink market increased 240% between the years 2004 and 2008 and is expected to continue to grow. Growth of this market is concerning because energy drink consumption has been associated with a variety of health risk behaviors including increased marijuana use, sexual risk-taking, fighting, alcohol consumption, but little research has explored the relationship between energy drinks and dietary behaviors of emerging adults. Therefore, the purpose of this study was to explore the relationship between energy drink consumption and diet among a sample of emerging adults. Participants included 585 undergraduate students from a large, public US university (m age=18.7; 47% non-Hispanic White, 20.9% Hispanic, 25.5% Asian, 2.7% non-Hispanic Black, and 4.4% other; 56% Female). Using an online survey, students self-reported energy drink consumption and dietary behaviors. Past week and past month energy drink consumption was measured with single items asking the number of times and the number of days the student consumed an energy drink, respectively. Dietary behaviors measured included soda, diet soda, milk, sweet snacks, salty snacks, fruits, vegetables, breakfast, frozen food meals, fast food meals, and restaurant meals consumption in a usual week. Summing responses to items including weekly consumption of milk, fruits, vegetables, and breakfast created a healthy eating index. Similarly, summing responses on items including weekly consumption of soda, diet soda, sweet snacks, salty snacks, frozen food, fast food, and restaurant food created an unhealthy eating index. Linear regression analyses were run to determine the associations between energy drink consumption and the individual dietary behaviors as well as the healthy and unhealthy eating indices. All analyses controlled for gender, race/ethnicity, and body mass index (BMI). Additional models were run with gender as a moderator to determine if the associations between energy drink consumption and dietary behaviors differed by gender. Overall, 17.5% of students consumed energy drinks at least one time in the past week (12.6% male, 5.0% female), and 38.1% consumed energy drinks on at least one day in the past month (22.7% male, 15.4% female). Increased past month energy drink consumption was associated with a higher score on the unhealthy eating scale (B=0.25 (SE =0.13), p=0.001), soda consumption (B=0.11 (SE =0.05), p=<0.001), and diet soda consumption (B=0.07 (SE =0.04), p=0.007), and a lower score on the healthy eating scale (B=-0.27 (SE=0.17), p<0.05). Increased past week energy drink consumption was associated with a higher score on the unhealthy eating score (B=0.80 (SE =0.28), p=<0.001), soda (B=0.25 (SE =0.10), p=0.003), diet soda (B=0.20 (SE =0.09), p=0.003), pre-packaged salty snacks (B=0.16 (SE =0.09), p=0.04), and frozen meal consumption (B=0.16 (SE =0.05), p=<0.002). No moderation effect was found by gender. Results suggest that those students who consume more energy drinks also consume more unhealthy foods and beverages. Given these associations, it is important that interventions aimed at addressing diet quality, overweight, or obesity rates within this population also consider the implications of energy drink consumption as a risk factor. / text

Constructing and validating the large inventory of frequent experience : personality based on everyday behaviors

Niederhoffer, Kate Gaynor 28 April 2015 (has links)
What is the best way to account for the variety of human experience? The range of ways to understand individuals has been debated across myriad domains of study without consensus. Rarely have the solutions involved the role of the observable behaviors of daily life; instead inferences are made from traits, opinions, beliefs, or needs. The current dissertation proposes assessing personality through the lens of time, focusing on individual differences in the objective, real world transactions of everyday behaviors. To accomplish this goal an inventory was created to closely approximate the totality of everyday behavioral life and explore its relation to traditional measures of personality. Study 1 analyzed the structure of behaviors in the American Time Use data as an aid in item generation within a narrowed, but comprehensive scope of the behavioral landscape. A thorough set of criteria were then applied to tailor the inventory towards measuring objective, high incidence, quotidian behaviors of psychological interest. In Study 2, the assembled 78-item behavioral inventory was administered to a large, diverse sample to explore the structure of everyday behaviors; the stability of behaviors over time; individual differences in everyday behaviors; the relationship of everyday behaviors to various measures of personality; and, the covariance of the behaviors with the language of everyday life. Six major dimensions of everyday behaviors were identified and found to be internally consistent and reliable over time. The dimensions demonstrated unique variance as a function of age, sex, and personality. The self-report format of this method of assessing everyday behaviors was shown to be construct valid in that analyses of open-ended linguistic descriptions of routine weekend behaviors paralleled the patterns of activity reported. The broader implications of assessing personality by way of everyday behaviors are discussed in that behaviors can be thought of as an enduring signature that implicitly incorporate our values, attitudes, beliefs, and overall means of expression. / text

Understanding click and brick shopping : development of consumer typology

Kuni, Katherine Ann 12 August 2015 (has links)
Little previous research has been conducted concerning consumer shopping behaviors when dealing with stores that have both physical and online outlets where products can be browsed or bought, also known as "click and brick" retailers. This exploratory study seeks to determine if distinct "click and brick" consumer typologies can be formed according to consumers' preferred method of shopping. This study also examines the relationships between consumer's needs for convenience, product tangibility, social interaction and levels of trust and their preferred method of "click and brick" shopping. While significant differences were found between shopping preferences, results indicated that consumer preference significantly differs depending on the store or product type implying that an overall "click and brick" consumer typology cannot be formed. Also, results indicate that the two shopping preferences that significantly differ the most depending on motivations are still "browse and buy in store" and "browse and buy online," indicating that consumers do not heavily utilize multichannel shopping methods for purchases. / text

African Americans and HIV/AIDS-related bereavement: an exploratory study of loss, coping, and help-seeking

Allen, Sydnye Dyan 14 October 2009 (has links)
The purpose of this study was to understand how individuals from African American families process the HIV/AIDS-related bereavement of a loved one. A sample of African American adults age 18 and older who experienced the loss of a loved one to HIV/AIDS-related death were interviewed for this study. Qualitative methodology was employed for data collection and thematic analysis was used to identify central themes. Due to the exploratory nature of the study, emergent themes regarding AIDS related bereavement were expected. It was postulated that African American individuals shared experiences related to HIV/AIDS-related loss. Individuals were also expected to report unique bereavement experiences. In particular, prolonged grief and internalized coping strategies were expected to impact bereavement experiences of individuals in families acutely affected by HIV/AIDS-related stigmatization. Secrecy about a loved one’s HIV/AIDS-related death was expected to impact the ability of bereaved persons to process and effectively cope with loss; results yielded evidence of protracted states of shame or blame regarding loss. The findings of this study are useful for identifying methods for targeting bereavement resources toward individuals who are underrepresented in HIV/AIDS-related intervention programs. / text

Neuropsychological functioning of conduct disorder impacted by age of onset and comorbid attention-deficit/hyperactivity disorder

Kerne, Valerie Van Horn 25 July 2011 (has links)
Conduct Disorder is a disruptive behavior disorder listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision (DSM-IV-TR). Considering the prevalence and severity of Conduct Disorder and the social and economic impact, research is needed to address subtype and comorbidity. The purpose of the present study is to investigate the impact of Conduct Disorder age of onset by comparing neuropsychological functioning between adolescents diagnosed with Conduct Disorder, childhood-onset and adolescents diagnosed with the adolescent onset subtype of Conduct Disorder. In addition, the study will investigate the impact of a comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) diagnosis. Exploration into the neuropsychological functioning of Conduct Disorder while considering comorbidity with ADHD is needed to clarify cognitive functioning profiles of children and adolescents diagnosed with Conduct Disorder. / text

The Reader and the Librarian

Condon, Scott January 2007 (has links)
This paper explores the experience of reading from the readerâ s perspective, drawing on research conducted by Louise Rosenblatt and Catherine Sheldrick Ross. Rosenblattâ s transactional theory of reading is described and contrasted with contemporary library practices, and these different approaches serve to exemplify the poles of what she calls the efferent-aesthetic continuum. Library educators and practitioners tend to reside at one end of the continuum and emphasize goal-oriented searching with pre-defined needs and specifically articulated questions; at the other end we encounter the complex cognitive, emotional, imaginative, associative and experiential transactions that engage pleasure readers. The medium of the book is briefly examined, as are the purposive skills that can emerge from the practice of reading for pleasure. To better serve readers, the largest body of library users, it is incumbent upon the library profession to understand the detailed processes and characteristics that constitute the reading experience.

The challenging and critical role of information professionals in combating AIDS in India

Ghosh, Maitrayee, Bhatt, Jay January 2006 (has links)
The nature of work for librarians/information professionals is undergoing a profound transformation, due to the arrival of deadly diseases like AIDS (Acquired Immunodeficiency Syndrome) and the change in information needs of the local community. This change necessitates much more professional expertise, updated knowledge, critical thinking and involvement in developing effective AIDS literacy programs. Information professionals serving in different libraries or potential information dissemination centers can provide dedicated services to society by helping to access AIDS information not only in urban settings but also in rural environments. This paper outlines strategies for effective collaboration in the context of AIDS literacy promotion efforts. It identifies a number of obstacles in the process of empowering the community and suitable measures essential for success.

Figure and Table Retrieval from Scholarly Journal Articles: User Needs for Teaching and Research

Sandusky, Robert J., Tenopir, Carol, Casado, Margaret M. January 2007 (has links)
This paper discusses user needs for a system that indexes tables and figures culled from scientific journal articles. These findings are taken from a comprehensive investigation into scientistsâ satisfaction with and use of a tables and figures retrieval prototype. Much previous research has examined the usability and features of digital libraries and other online retrieval systems that retrieve either full-text of journal articles, traditional article-level abstracts, or both. In contrast, this paper examines the needs of users directly searching for and accessing discrete journal article components â figures, tables, graphs, maps, and photographs â that have been individually indexed.

Semantic Issues for Digital Libraries

Chen, Hsinchun January 2000 (has links)
Artificial Intelligence Lab, Department of MIS, University of Arizona / As new and emerging classes of information systems applications the applications become more overwhelming, pressing, and diverse, several well-known information retrieval (IR) problems have become even more urgent in this “network-centric” information age. Information overload, a result of the ease of information creation and rendering via the Internet and the World Wide Web, has become more evident in people’s lives. Significant variations of database formats and structures, the richness of information media, and an abundance of multilingual information content also have created severe information interoperability problems-structural interoperability, media interoperability, and multilingual interoperability. The conventional approaches to addressing information overload and information interoperability problems are manual in nature, requiring human experts as information intermediaries to create knowledge structures and/or ontologies. As information content and collections become even larger and more dynamic, we believe a systemaided bottom-up artificial intelligence (AI) approach is needed. By applying scalable techniques developed in various AI subareas such as image segmentation and indexing, voice recognition, natural language processing, neural networks, machine learning, clustering and categorization, and intelligent agents, we can provide an alternative system-aided approach to addressing both information overload and information interoperability.

Gender and Communication Styles on the World Wide Web

Sutcliffe, Tami January 1998 (has links)
Certain human communication traits have historically been identified as gender-specific. The purpose of this paper is to collect and compare the most widely-indexed, gender-specific World Wide Web sites from five given interest areas, and to then determine which, if any, traditionally gender-based communication patterns were present within these sites. Using qualitative and quantitative analysis, this study found that in many cases: * Female-oriented sites in this study emphasized communality * stressed sharing personal experience * resisted authoritative language * encouraged emotional interaction # Male-oriented sites in this study relied on authoritative language # emphasized privacy # stressed professionalism # minimized personal interaction . Although these sites represent only a miniscule "snap shot" of communication on the Web, they seemed to suggest that the core of traditionally identified gender-specific communication traits is being actively transplanted into Cyberspace.
