Honors College Retention In The College Of Agriculture, Food And Environmental, Sadie Vander Wal Mar 2022

Honors College Retention In The College Of Agriculture, Food And Environmental, Sadie Vander Wal

Honors Capstone Projects

The College of Agriculture, Food and Environmental Sciences (CAFES) at South Dakota State University (SDSU) has the second lowest Honors College student enrollment compared to all other colleges in the university. This study explores factors that deter CAFES students from enrolling or continuing with Honors and potential opportunities to encourage enrollment and retention. A QuestionPro survey and focus groups were utilized in collecting responses from first-year CAFES students on their awareness of the Honors College’s automatic enrollment, factors that deter students from pursuing Honors, and opportunities. Survey responses (n=59) were reported as percentages. Randomized focus groups were created from the …

A Vision For The Northern Great Plains, Dr. Cornelia Butler Flora Feb 2022

A Vision For The Northern Great Plains, Dr. Cornelia Butler Flora

Great Plains Sociologist

This essay presents a number of positive alternatives for the future of the rural Northern Great Plains. A number of trends occurring in the 1990s are used to assemble this vision, such as sustainable agriculture, information technology, wireless communication, and small communities working together in mutual interest. This vision identifies the important role of social capital and social relationships as rising in value over a consumer oriented society. The strength of a positive vision exists in its ability to fire people to actively seek these ends, [ed.]


Three Theories Of The Future Of The Great Plains, Scot A. Stradley Feb 2022

Three Theories Of The Future Of The Great Plains, Scot A. Stradley

Great Plains Sociologist

The purpose of this paper is to present three theories of the future of the Great Plains. The theories consist of two extremes, based on the differences between supply and demand. Two of the three theories of the future of the Great Plains are supply side. One is a demand side theory. One or more of these theories can be found in public policy debates affecting the Plains.


The Not So Wonderful World Of Disney: An Exploratory Content Analysis Of Gender Themes In Disney Full Length Animated Feature Films, Beth Wiersma Feb 2022

The Not So Wonderful World Of Disney: An Exploratory Content Analysis Of Gender Themes In Disney Full Length Animated Feature Films, Beth Wiersma

Great Plains Sociologist

Research has focused on the gender messages portrayed in television programs, cartoons, advertisements, literature, picture books, and fairy tales. One venue not included in the research is the Disney full-length animated feature films. The initial research on which this article is based was an exploration of the themes of gender, violence and anthropomorphism in Disney films. Emergent themes include heterosexual couplings, family constellations, good versus evil, and villains. This article will cover only the gender themes. Five areas were used to code gender content which include: physical appearance, personality traits, in-home labor, out of home employment, and societal and familial …

The Importance Of College Student Academic Goals: A Symbolic Interactionist Approach, Donald E. Arwood, Donna J. Hess Feb 2022

The Importance Of College Student Academic Goals: A Symbolic Interactionist Approach, Donald E. Arwood, Donna J. Hess

Great Plains Sociologist

A cross-sectional study of a sample of first and second year students attending a moderately-sized, Great Plains university is used to demonstrate the correlation between academic self-conceptions and academic goals. Multiple regression analysis shows that academic self-conceptions, academic role-taking, job goals, being a parent, and having a Job are excellent predictors of academic goals. The authors recommend that the symbolic interactionist perspective used in the study should be used to study how academic goals link academic self-conceptions with academic behaviors and outcomes.

Ethnic Minorities In The People's Republic Of China, Mary Jo Benton Lee Feb 2022

Ethnic Minorities In The People's Republic Of China, Mary Jo Benton Lee

Great Plains Sociologist

In the People's Republic of China, the term "minority nationality" denotes a member of one of China's 55 officially recognized ethnic minority groups. Minority nationalities have traditionally been regarded as those who have cultures (particularly languages and religions) that atv distinct from the Han Chine.ie majority. This article focuses on ethnic minorities in China-their significance to the PRC as a whole, the official classification system by which the government identifies them and the history of their interaction with the majority Han population. Higher education in the PRC is discussed with an emphasis on national minority institutes. Two macro issues relating …


Social Claims, Ownership, Metaphor And Cross-Sex Relations: Why Women Are Property, Mark Hansel Feb 2022

Social Claims, Ownership, Metaphor And Cross-Sex Relations: Why Women Are Property, Mark Hansel

Great Plains Sociologist

Property is a pervasive metaphor in our society that is the source of the social meaning of social claims to such wide ranging social objects as traffic lanes and restaurant tables. These claims are attempts to appropriate temporary control of the objects. Similarly, claims to a persons' attention and claims for services are attempts to appropriate control of resources of an individual. Successful appropriation transforms resources into the temporary (metaphoric) property of the claim maker. Some claims to social resources are legitimate and others deviant. The legitimacy of social claims is in part dependent upon authority relations between persons.

Elwyn Robinson And Settlement Patterns In North And South Dakota, Alan Fricker Feb 2022

Elwyn Robinson And Settlement Patterns In North And South Dakota, Alan Fricker

Great Plains Sociologist

What is probably Elwyn Robinson's most enduring legacy is his six themes of North Dakota history. He used them as his theory to explain how and why North Dakota was settled and developed the way it did. To an extent, he also used them to prophesize North Dakota's future.


Animal Rights, Government Regulations, And Rural Economies: An Examination Of Factors Contributing To The Economic Future Of Rural Communities, Dana C. De Witt Feb 2022

Animal Rights, Government Regulations, And Rural Economies: An Examination Of Factors Contributing To The Economic Future Of Rural Communities, Dana C. De Witt

Great Plains Sociologist

The purpose of this paper is to examine the increased role animal-rights organizations play in shaping attitudes and regulations that impact the long term viability of rural economies. The animal-rights movement is comprised of a highly diversified, often secretive, loosely linked network of groups. This creates a certain amount of difficulty in describing "first hand" the attitudes, values, and goals of these groups. A variety of animal production and other animal based industries were examined in terms of their contribution to rural, as well as state, economies. Secondary data analysis was performed on several sociological, animal rights, hunting and trapping, …

Attitudes Toward The Environment: How Do The Attitudes Of Conventional, No-Till, And Organic Farmers Compare?, George A. Youngs, David L. Watt Feb 2022

Attitudes Toward The Environment: How Do The Attitudes Of Conventional, No-Till, And Organic Farmers Compare?, George A. Youngs, David L. Watt

Great Plains Sociologist

One of Che key dynamics in today's increased interest in alternative fanning is concern for the environment (Beus and Dunlap, 1990). Many advocates of alternative farming argue that conventional farming harms the environment and may even destroy the future of agriculture. The implicit, and often explicit, notion associated with this view is that conventional farmers are less concerned about the environment than are alternative farmers. The present study will test this notion by comparing the attitudes toward the environment of conventional farmers with two types of alternative farmers, organic and no-till. By definition, conventional farmers are those farmers who practice …


Ideological Currents Of The Rural Crisis: The Fats, Small Town, And Rural Peoples' Conf, Thomas C. Langham Feb 2022

Ideological Currents Of The Rural Crisis: The Fats, Small Town, And Rural Peoples' Conf, Thomas C. Langham

Great Plains Sociologist

The rural crisis of the 1900s plowed a deep furrow across the economic, political, cultural, social, and psychological landscape of the Upper Midwest. Rooted in the financial problems of farmers, the crisis rippled not only through farm families but also into the region's small towns (Buttel, 1909; "Farm Crisis," 1986; Cinder et al., 1986; Heffernan and Heffernan. 1986; Rosenblatt, 1990: 3-13). Responses to the crisis were many and varied. Some people, although in actual numbers only slightly greater than the previous fifty years, followed perhaps the most traditional response to rural crisis and fled in search of work to more …


Session 2: A Vision Guidance System On Agricultural Sprayers Reduces Operator Stress, Travis Burgers, Kelly Vanderwerff Feb 2022

Session 2: A Vision Guidance System On Agricultural Sprayers Reduces Operator Stress, Travis Burgers, Kelly Vanderwerff

SDSU Data Science Symposium

Manually operating an agricultural sprayer is a stressful activity. Operators work an average of 15 hrs/day in peak season [1], navigating 38-cm (15-in) tires in 76-cm (30-in) rows. Guidance systems can relieve operator fatigue [2]. A commercially-available vision guidance system (VSN®, Raven Industries) is available for agricultural vehicles.

Human subject protocols were approved by the IRB. Three experienced male operators drove manually and with VSN in the same field. Each wore an Empatica E4 wristband to measure their electrodermal activity (EDA). Sprayer steering status was recorded from the sprayer guidance system (RS1TM, Raven Industries). EDA data was filtered with a …


Economic Hardship And Stress Among Farm Operators In North Dakota: The Suffering Effect Of Social Support, Kevin A. Kettner, Jack M. Geller, Richard Ludtke, Janet Kelly Feb 2022

Economic Hardship And Stress Among Farm Operators In North Dakota: The Suffering Effect Of Social Support, Kevin A. Kettner, Jack M. Geller, Richard Ludtke, Janet Kelly

Great Plains Sociologist

The changing economic character of American agriculture is producing more than just surplus crops, it is also producing measurable increases in stress. This stress is a consequence of the faltering economic conditions in rural America (Cogner et. al,, 1986; Farmer, 1986), which has significant implications for the well-being of our rural population. Long term depression, increased suicide rates, family strain and violence are all results of this economic change (Farmer, 1986). Faraer (1986), characterized the rural sector as financially, emotionally, and socially troubled. These troubles are directly linked to the economic crisis rural America is experiencing. Social scientists and mental …

The Nexus Of Gut Microbiota, Diet, And Health, Sajal Bhattarai, Srinivas Janaswamy Feb 2022

The Nexus Of Gut Microbiota, Diet, And Health, Sajal Bhattarai, Srinivas Janaswamy

Dairy Science and Food Science Faculty Publications: 2022 to Present

The gut microbiome incorporates the ecological niche specific to the totality of the microorganisms in the human gut. Unique to every individual, the blueprint of the microbiome sets up at birth and functions as a human organ and plays a significant role in digestion, detoxification, fighting pathogens, modulating the immune system, and improving health. The gut microbiota and associated health implications are influenced by factors such as birth and age, diseases, use of antibiotics and food components (e.g., complex carbohydrates and dietary fibers, plant proteins, unsaturated fatty acids, and functional compounds of natural origin such as flavones, flavonoids, polyphenols, and …

Perspective Of Dairy Producers From California, Idaho, South Dakota, And Washington: Health And Business Implications Of The Covid-19 Pandemic During The Second Wave, Ainhoa Valldecabres, J. Wenz, Fernanda Ferreira, Mireille Chahine, Joseph Dalton, Mario E. De Haro-Martí, Maristela Rovai, Noelia Silva-Del-Rio

Dairy Science and Food Science Faculty Publications: 2022 to Present

The aim of this study was to document California, Idaho, South Dakota, and Washington dairy producers' perspectives on the health and business implications of COVID-19 during the pandemic second wave. Dairy producers were reached by a 14-question anonymous mail survey during June and July of 2020. We obtained 226 responses (response rate: 9.3% CA, 8.6% ID, 31.4%, and 10.0% WA). Responses were grouped by state (CA: 48.7%, ID: 15.9%, SD: 21.7%, or WA: 13.7%) and dairy size [based on number of cows; small (<100): 14.1%, medium (100–499): 27.7%, medium-large (500–1,999): 33.2%, or large (≥2,000): 25.0%]. Survey responses were summarized, and multiple correspondence analysis was used to map responses and identify data clusters. At the time of the survey, some respondents suspected (3%) or had confirmed (9%) COVID-19 cases on their premises. Respondents were somewhat or very concerned about the health (75%) and business (92%) implications associated with COVID-19. Producers were concerned about the health of their families, employees, and employees' families; having to reduce production; workforce shortage; limited goods availability; and lack of services. Producers perceived that their employees were somewhat or very concerned (74%) with the pandemic. There was COVID-19 safety information or training provided (78%) or intended (4%) in English (22%), Spanish (23%), or both (55%). The focus of training was as follows: how to remain healthy at work (91%) and at home (60%), what to do if a worker gets sick (77%), and sick leave information (54%). Nevertheless, 18% of the respondents answered that training was not going to be provided. The following control measures implemented: providing hand sanitizer or disinfectant wipes (78%), instruction on frequent hand-washing (76%), social distancing (59%), prevention of employee gatherings (54%), providing and requiring the use of face masks (49%), and limiting on-farm visitors (44%). Multiple correspondence analysis showed that concern with health …

Belowground Mechanism Reveals Climate Change Impacts On Invasive Clonal Plant Establishment, Surendra Bam, Jacqueline P. Ott, Jack L. Butler, Lan Xu Feb 2022

Belowground Mechanism Reveals Climate Change Impacts On Invasive Clonal Plant Establishment, Surendra Bam, Jacqueline P. Ott, Jack L. Butler, Lan Xu

Natural Resource Management Faculty Publications

Climate change and disturbance can alter invasion success of clonal plants by differentially affecting the clonal traits influencing their establishment as young plants. Clonal traits related to the vegetative reproduction of native Pascopyrum smithii and non-native Bromus inermis grass seedlings were evaluated under altered precipitation frequencies and a single grazing event. Pascopyrum smithii maintained similar vegetative reproduction under three simulated precipitation frequencies whereas B. inermis vegetative reproduction declined as precipitation became more intermittent. Vegetative reproduction of the non-native B. inermis was greater than the native P. smithii under all simulated precipitation frequencies except the most intermittent scenario. A single grazing …
