The Interplay Of Traits And Motives On Volunteering: Agreeableness, Extraversion And Prosocial Value Motivation, Gustavo Carlo, Morris A. Okun, George Knight, Maria Rosario T. De Guzman

Department of Psychology: Faculty Publications

Social psychology and personality theorists have proposed that our understanding of prosocial behavior will be enhanced by examining the interplay of traits and motives. The present study was designed to test several pathways by which agreeableness, extraversion, and prosocial value motivation to volunteer influence volunteerism. A sample of 796 college students completed measures of the Big Five traits, prosocial value motivation to volunteer, and volunteering. Results of path analyses showed that prosocial value motivation to volunteer partially mediated the relations between agreeableness and extraversion, and volunteering. Furthermore, as agreeableness decreased, extraversion was more strongly related to prosocial value motivation to …

Insulin Signaling Is Necessary For Vitellogenesis In Drosophila Melanogaster Independent Of The Roles Of Juvenile Hormone And Ecdysteroids: Female Sterility Of The Chico1 Insulin Signaling Mutation Is Autonomous To The Ovary, David S. Richard, Robert Rybczynski, Thomas G. Wilson, Yue Wang, Marta L. Wayne, You Zhou, Linda Partridge, Lawrence G. Harshman

Lawrence G. Harshman Publications

It has been suggested that insulin signaling mutations of Drosophila melanogaster are sterile and long-lived because of juvenile hormone (JH) and ecdysteroid deficiency. However, female sterility of an insulin/IGF-like signaling mutant (chico¹) of D. melanogaster is not mediated by downstream systemic signaling in terms of major alterations in JH or ecdysteroid levels. chico¹ is a null mutation in the insulin substrate protein (CHICO) gene of D. melanogaster. Homozygous chico1 females are sterile and their oocytes do not mature beyond the last previtellogenic stage. Homozygous chico1 females exhibit approximately wild-type rates of JH biosynthesis, ovarian release …

Review Of Women Oral History: The Frontiers Reader Edited By Susan H. Armitage With Patricia Hart And Karen Wathermon., Yuankun Yao

Journal of Women in Educational Leadership

Women's Oral History: The Frontiers Reader is a collection of 21 journal articles. Edited by Susan H. Armitage, with Patricia Hart and Karen Weatherman, the book chronicles the evolution of women's oral history from its beginning in the 1970s to the present. The book documents how oral history provides an alternative perspective on history by uncovering important roles ordinary women have played-roles that have been typically ignored by mainstream history (Clegg, Miller, & Vanderhoof, 1995; Singleton, 1990).

Maternal Age As A Determinant Of Larval Growth And Survival In A Marine Fish, Sebastes Melanops, Steven A. Berkeley, Colin Chapman, Susan M. Sogard

United States Department of Commerce: Staff Publications

Relative body size has long been recognized as a factor influencing reproductive success in fishes, but maternal age has only recently been considered. We monitored growth and starvation resistance in larvae from 20 female black rockfish (Sebastes melanops), ranging in age from five to 17 years. Larvae from the oldest females in our experiments had growth rates more than three times as fast and survived starvation more than twice as long as larvae from the youngest females. Female age was a far better predictor of larval performance than female size. The apparent underlying mechanism is a greater provisioning …

Whispers And Sighs: The Unwritten Challenges Of Service–Learning, Rona J. Karasik

To Improve the Academy: A Journal of Educational Development

Documentation of the benefits of service-learning abound, and published case studies of successful service-learning programs may be found for a variety of disciplines. Faculty new to service-learning, however, are likely to find themselves facing a variety of unexpected challenges. While these challenges are neither insurmountable nor unknown to experienced service-karning practitioners, they can make starting a service-learning program remarkably time-consumingand unnecessarily frustrating. Unfortunately. pitfalls and program flops are rarely published. This chapter forewarns some of the challenges associated with service-learning and offers realistic approaches to dealing with them successfully.

Methionine Sulfoxide Reductase Regulation Of Yeast Lifespan Reveals Reactive Oxygen Species-Dependent And -Independent Components Of Aging, Ahmet Koc, Audrey P. Gasch, Julian C. Rutherford, Hwa-Young Kim, Vadim N. Gladyshev

Department of Biochemistry: Faculty Publications

Aging is thought to be caused by the accumulation of damage, primarily from oxidative modifications of cellular components by reactive oxygen species (ROS). Here we used yeast methionine sulfoxide reductases MsrA and MsrB to address this hypothesis. In the presence of oxygen, these antioxidants could increase yeast lifespan and did so independent of the lifespan extension offered by caloric restriction. However, under ROS-deficient, strictly anaerobic conditions, yeast lifespan was shorter, not affected by MsrA or MsrB, and further reduced by caloric restriction. In addition, we identified changes in the global gene expression associated with aging in yeast, and they did …

Effects Of Cognitive Behavioral Treatment On Physical Health Status In Patients With Panic Disorder, Norman B. Schmidt, Beth T. Mccreary, John J. Trakowski, Helen T. Santiago, Kelly Woolaway-Bickel, Nicholas Ialongo

Uniformed Services University of the Health Sciences

The relationship between panic disorder and nonpsychiatric medical illness is complex, but some evidence suggests that panic disorder increases risk for a variety of nonpsychiatric medical conditions. Given the demonstrated efficacy of cognitive behavioral therapy (CBT) for panic disorder, we were interested in evaluating the effects of CBT for panic disorder on nonpsychiatric medical symptoms among these patients. Patients were randomized to a 12-week group-administered CBT protocol (n = 22) or a delayedtreatment conlrol (n = 24). Treated patients showed marked improvement in both anxiety symptoms and physical health symptom ratings that were evident at midtreatment and were …

Life Span Extension Of Drosophila Melanogaster: Genetic And Population Studies, Lawrence G. Harshman

Lawrence G. Harshman Publications

During the past two decades, genetic studies of model organisms have been the most important tool underlying advances in understanding the biological basis of aging and longevity. Drosophila melanogaster, the geneticist's "fruit fly," is a model organism because it has been the focus of genetic studies for more than 90 years. This review argues that studies on D. melanogaster will make an especially important contribution to the field of aging and longevity at the intersection of research on genetics, complex traits, and fly populations.

Five approaches have been used to study the genetics of longevity of D. melanogaster: …

Mexican-Descent Latinas’ Compliance With Cervical Cancer Screening Guidelines, Evelinn A. Borrayo, Awilda Reyes

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

High mortality from invasive cervical cancer among Mexican-descent Latinas living in the Great Plains could be substantially reduced if they would utilize screening procedures regularly. To understand possible influential factors on their screening behaviors, we investigated which variables differentiate women age 50 and older who are most compliant with cervical cancer screening guidelines from those who are less compliant. Of 184 women surveyed, 100 were compliant with a yearly Pap smear while 84 were not compliant. Discriminant function analysis revealed that, apart from the significance of sociodemographic factors and acculturation, women who were most compliant significantly received more health-care provider …

Contradictions Of Interaction For Wives Of Elderly Husbands With Adult Dementia, Leslie A. Baxter, Dawn O. Braithwaite, Tamara D. Golish, Loreen N. Olson

Department of Communication Studies: Faculty Publications

The researchers used a dialectical framework to examine interviews with wives whose elderly husbands experienced adult dementia from Alzheimer’s disease and related disorders (ADRD), centering on how wives coped communicatively with their husbands’ illness. These “married widows” experienced a primary contradiction between their husbands’ physical presence and cognitive/emotional absence. Interwoven with the presence-absence contradiction were three additional contradictions: certainty-uncertainty, openness-closedness, and past-present. Results describe the ways these wives communicatively negotiated the web of contradictions as they interacted in the present with husbands they once knew. Applications for practitioners and caregivers working with ADRD patients and their wives, including formal and …

A Mortality Cost Of Virginity At Older Ages In Female Mediterranean Fruit Flies, James R. Carey, Pablo Liedo, Lawrence G. Harshman, Ying Zhang, Hans-Georg Müller, Linda Partridge, Jane-Ling Wang

Lawrence G. Harshman Publications

Mortality rates were measured over the lifetime of 65,000 female Mediterranean fruit flies, Ceratitis capitata, maintained in either all-female (virgin) cages or cages with equal initial numbers of males, to determine the effect of sexual activity and mating on the mortality trajectory of females at older ages. Although a greater fraction of females maintained in all-female (virgin) cages survived to older ages, the life expectancy of the surviving virgins was less than the life expectancy of surviving non-virgins at older ages. This was due to a mortality crossover where virgin flies experience lower mor-tality than mated flies from eclosion to …

“Married Widowhood”: Maintaining Couplehood When One Spouse Is Living In A Nursing Home, Dawn O. Braithwaite

Department of Communication Studies: Faculty Publications

When a marital partner moves to a nursing home, how do community-dwelling spouses, labeled “married widows,” adapt and cope with changes in the relationship and their own marital roles? The first goal of this study was to explore the role additions and deletions for community-based wives whose husbands moved to a nursing home. The second goal was to examine how these women discursively represent their own self-identity and the relationship they have with their husband who is living in a nursing home. Data were drawn from in-depth, face-to-face interviews with 21 wives whose husbands resided in a nursing home. A …

Life History Response Of Mediterranean Fruit Flies To Dietary Restriction, James R. Carey, Pablo Liedo, Lawrence G. Harshman, Ying Zhang, Hans-Georg Müller, Linda Partridge, Jane-Ling Wang

Lawrence G. Harshman Publications

The purpose of this study was to investigate medfly longevity and reproduction across a broad spectrum of diet restriction using a protocol similar to those applied in most rodent studies. Age-specific reproduction and age of death were monitored for 1,200 adult males and 1,200 females, each individually maintained on one of 12 diets from ad libitum to 30% of ad libitum. Diet was provided in a fixed volume of solution that was fully consumed each day, ensuring control of total nutrient consumption for every fly. Contrary to expectation and precedence, increased longevity was not observed at any level of …

Food Pulses Increase Longevity And Induce Cyclical Egg Production In Mediterranean Fruit Flies, James R. Carey, Pablo Liedo, Lawrence G. Harshman, X. Liu, Hans-Georg Müller, Linda Partridge, Jane-Ling Wang

Lawrence G. Harshman Publications

1. Inasmuch as virtually all studies on mortality and reproduction in insects are conducted under conditions in which food availability is constant, little is known about the demographic response of insects to variable food environments. For example, it is not known if and to what extent the life expectancy of insects subjected to shortages of high-quality food will increase and/or whether this increase is associated with major decreases in lifetime reproduction.

2. Therefore cohorts of 100 individual female medflies were subjected to different sets of conditions of protein availability (interspersed with sugar-only diets) including ad libitum sugar-only (no protein), ad …

Family Relationship Histories, Intergenerational Relationship Quality, And Depressive Affect Among Rural Elderly People, Les B. Whitbeck, Dan R. Hoyt, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Based on a sample of matched adult children and aging parents in the rural Mid¬west, this study examined the effects of family relationship history on depressive symptoms among elderly parents. The study used reports from both adult chil¬dren and aging parents regarding intergenerational affectional solidarity and re¬lationship strain. Aging parents reported levels of depressed affect. Adult chil¬dren’s recalled early relationships with their parents were associated with elderly parents’ reports of depressed affect through the effects of early family relation¬ships on contemporary relationships. Reports of early relationships and contem¬porary relationships were separated by 5 years. It is suggested that family rela¬tionship …

Female Sensitivity To Diet And Irradiation Treatments Underlies Sex-Mortality Differentials In The Mediterranean Fruit Fly, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Brad Love, Lawrence G. Harshman, Linda Partridge

Lawrence G. Harshman Publications

Large-scale experiments on medflies that were subjected to sterilizing doses of ionizing radiation (plus intact controls) and maintained on either sugar-only or full, protein-enriched diets revealed that, whereas the mortality trajectories of both intact and irradiated male cohorts maintained on both diets are similar, the mortality patterns of females are highly variable. Mean mortality rates at 35 days in male cohorts ranged from 0.2 to 0.3 but in female cohorts ranged from 0.09 to 0.35, depending on treatment. The study reports three main influences: (a) qualitative differences exist in the sex–mortality response of medflies subjected to dietary manipulations and irradiation, …

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

This study compares and contrasts InfoTrac and ProQuest primarily as full-text resources to supplement retrieval of references contained in the CINAHL database. These databases are analyzed by examining their scope in terms of the number and types of serials covered within specific areas using Ulrich's subject headings. Another important aspect of this study relates to the effectiveness of the two search engines for end-user retrieval and collection development.

The Effects Of An Acute Stressor On Depressive Symptoms Among Older Adults: The Moderating Effects Of Social Support And Age, Kimberly A. Tyler, Dan R. Hoyt

Department of Sociology: Faculty Publications

This study uses longitudinal data to examine the potential moderating effects of social support and age among older adults exposed to an acute stressor. Using a sample of 651 older persons, data were gathered in the spring of 1992 and in the fall of 1993, approximately 60 days after the peak impact of flooding in the Midwest. Results indicate a positive association between pre- and post-flood depression and a negative association between social support and post-flood depression. For the youngest of the two older age groups, there is also a positive association between flood exposure and post-flood depression, controlling for …

Interleukin-1 Polymorphisms Associated With Increased Risk Of Gastric Cancer, Emad M. El-Omar, Mary Carrington, Wong-Ho Chow, Kenneth E. L. Mccoll, Jay H. Bream, Howard A.

Helicobacter pylori infection is associated with a variety of clinical outcomes including gastric cancer and duodenal ulcer disease¹. The reasons for this variation are not clear, but the gastric physiological response is influenced by the severity and anatomical distribution of gastritis induced by H. pylori. Thus, individuals with gastritis predominantly localized to the antrum retain normal (or even high) acid secretion², whereas individuals with extensive corpus gastritis develop hypochlorhydria and gastric atrophy³, which are presumptive precursors of gastric cancer4. Here we report that interleukin-1 gene cluster polymorphisms suspected of enhancing production of interleukin-1-beta …

Oxidative Stress Resistance: A Robust Correlated Response To Selection In Extended Longevity Lines Of Drosophila Melanogaster?, Lawrence G. Harshman, Beth A. Haberer

Lawrence G. Harshman Publications

Stress resistance is associated with longevity in Drosophila melanogaster and other model organisms used for genetic research. The present study tests for oxidative stress resistance in one set of lines selected for late-life reproduction and extended longevity. Both females and males from the selected lines were appreciably more resistant to oxidative stress than were flies from the control lines. A relative increase in oxidative stress resistance is a correlated response to selection in this laboratory selection experiment. Increased oxidative stress resistance appears to be a relatively robust correlated response to laboratory selection for late-life reproduction and extended longevity.

Age-Dependent Characteristics Of Protection V. Susceptibility To Plasmodium Falciparum, J. Kevin Baird

United States Public Health Resources

Naturally acquired immunity to Plasmodium falciparum may be linked to key features of the immune system that change during normal development and ageing. Evidence of this was seen in non-immune Javanese transmigrants taking up residence in hyperendemic Irian Jaya, Indonesia. After 1± 2 years of residence, the adult migrants had less frequent and less intense parasitaemias than their children. Splenomegaly and malaria-like symptoms were also less common in the adults. These age-dependent patterns of relative resistance to P. falciparum mirrored those in lifelong residents. The Javanese adults acquired protective immunity against chronic exposure to infection relatively quickly compared with their …

Leisure And Aging In Southern Saskatchewan, Ralph Nilson, David Weaver, Carlton Yoshioka

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This study examined the psychological and socio-economic dimensions of the leisure experience patterns of the expanding older adult population in the Canadian Great Plains or Prairie region. Survey data were collected from a random sample of 2,969 of persons 65 years of age and older residing in southern Saskatchewan. Results indicated that older adults have a wide range of leisure activities with involvement in numerous individual and community related pursuits. However, when differentiated by season, winter activities tended to be passive, solitary, inexpensive, and home-based activities. Moreover, important psychological dimensions in perceived health and activity of older adults did not …

Memory Processes In Elderly Eyewitnesses: What We Know And What We Don’T Know, Brian H. Bornstein

Department of Psychology: Faculty Publications

Research is reviewed on the memory abilities of elderly eyewitnesses. Two major issues are addressed: First, how credible are elderly witnesses? Second, how accurate are they? Despite negative stereotypes regarding elderly eyewitnesses, they do not necessarily lack credibility at trial. In terms of their memory performance, older witnesses are as accurate as young adults in many respects, but they are particularly vulnerable to misleading information that is presented after the witnessed event. Furthermore, their performance varies depending on the type of information that is sought and the manner in which their memory is assessed. Recommendations are made for improving the …
