Evaluation Of Oxidant/Antioxidant Status And Ecp Levels In Asthma, Ömer Emecen, Berri̇n Berçi̇k İnal, Füsun Erdenen, Murat Usta, Hale Aral, Güvenç Güvenen
Turkish Journal of Medical Sciences
Inflammatory and immune cells, such as eosinophils, macrophages, and neutrophils, generate more reactive oxygen species in patients with asthma than they do in healthy individuals, and oxygen radicals contribute to tissue injury in asthma. We aimed to measure total oxidant status (TOS) and antioxidant status (TAS) in order to assess oxidative and antioxidative capacity. Eosinophil cationic protein (ECP), total IgE, and eosinophils (%) were measured to evaluate the level of inflammation. Materials and methods: The study included 56 non-smoking asthma patients that were followed-up at the respiratory disease and allergy outpatient clinics, where they received ongoing treatment for 5 months …

Dermatoglyphics As Markers Of Prenatal Disturbances In Schizophrenia: A Case-Control Study, Bi̇rsen Özyurt, Ahmet Songur, Mustafa Sarsilmaz, Ömer Akyol, Mustafa Namli, Reha Demi̇rel
Turkish Journal of Medical Sciences
Several studies have reported the importance of dermatoglyphics as markers of a prenatal disturbance in patients with schizophrenia. Due to the fact that finger- and handprints are formed by the end of the second trimester, they may provide clues to disturbances in early development. The aim of this study was to determine specific dermatoglyphical frequencies in a sample of patients with schizophrenia and normal controls. Materials and methods: Fingerprints and palm prints were obtained from 45 schizophrenic patients as well as 45 healthy controls. The dermatoglyphic patterns on the fingers (total finger ridge count [TFRC]) and palms (a-b, b-c, and …

While researchers have found a negative association between religiosity and pornography use, little, if any, research has examined the specific aspects of religiosity that might be related the use of pornography. Therefore, the purpose of this study of religious young men was to compare those who view pornography with those who do not on indices of (a) family relationships, (b) religiosity (i.e., beliefs, past/present personal religious practices, and past family religious practices), and (c) personal characteristics (identity development, depression, self-esteem, and drug use). Participants were 192 emerging-adult men ages 18-27 (M age = 21.00, SD = 3.00) attending a …
Compatibility Or Restraint? The Effects Of Sexual Timing On Marriage Relationships, Dean M. Busby, Jason S. Carroll, Brian J. Willoughby
Compatibility Or Restraint? The Effects Of Sexual Timing On Marriage Relationships, Dean M. Busby, Jason S. Carroll, Brian J. Willoughby
Faculty Publications
Very little is known about the influence of sexual timing on relationship outcomes. Is it better to test sexual compatibility as early as possible or show sexual restraint so that other areas of the relationship can develop? In this study, we explore this question with a sample of 2035 married individuals by examining how soon they became sexually involved as a couple and how this timing is related to their current sexual quality, relationship communication, and relationship satisfaction and perceived stability. Both structural equation and group comparison analyses demonstrated that sexual restraint was associated with better relationship outcomes, even when …
Nested Coloured Timed Petri Nets For Production Configuration Of Product Families, Lianfeng Zhang, Brian Rodrigues
Nested Coloured Timed Petri Nets For Production Configuration Of Product Families, Lianfeng Zhang, Brian Rodrigues
Research Collection Lee Kong Chian School Of Business
Production configuration is as an effective technique to deal with product variety while maintaining production stability and efficiency. It involves a diverse set of process elements (e.g., machines, operations), a high variety of component parts and assemblies and many constraints arising from product and process variety. Production configuration entails the selection and subsequent arrangement of process elements into complete production processes and the final evaluation of configured multiple alternatives. To better understand production configuration and its implementation, we study the underlying logic for configuring production processes using a dynamic modelling and visualisation approach. This is accomplished by developing a new …

Purpose – With globalization and knowledge-based production, firms may cooperate on a global scale, outsource parts of their administrative or productive units and negate location altogether. The extremely low transaction costs of data, information and knowledge seem to invalidate the theory of agglomeration and the spatial clustering of firms, going back to the classical work by Alfred Weber and Alfred Marshall, who emphasized the microeconomic benefits of industrial collocation. This paper aims to argue against this view and show why the growth of knowledge societies will rather increase than decrease the relevance of location by creating knowledge clusters and knowledge …

To evaluate the effective components of couple relationship education, 59 newlywed couples were randomly assigned to one of two couple relationship programs (CRE): (1) RELATE, which involved receiving feedback mono their relationship based on the on-line RELATE assessment; or (2) RELATE + Couple CARE, which was RELATE plus completing the 6 unit Couple CARE relationship skill training program. Relative to RELATE, RELATE + Couple CARE produced more improvement in couple communication, and high relationship satisfaction across the next 12 months in women. Men sustained high and similar relationship satisfaction in either condition. Skill training CRE has additional benefits for couples …

Understanding Positive Father-Child Interaction: Children's, Fathers', And Mothers' Contributions, Erin K. Holmes, Aletha C. Huston
Faculty Publications
Guided by a systemic ecological framework for father involvement, we investigate children's, mothers', and fathers' contributions to observed father-child interaction. Analyses of 586 married resident fathers, their wives, and a target first-grade child (participants in the NICHD Study of Early Child Care) demonstrate that an additive model of father involvement accounts for the quality of father-child interaction better than a model which focuses on only one component of the system. Father parenting beliefs, child language skills, child social skills, maternal employment, and dyadic mother-child interaction quality each additively and significantly contribute to positive father-child interaction. Father average income and education …

Part one of this review chapter provides a brief historical overview of the fathering role. Following this overview, some cultural contradictions and challenges facing fathers, particularly married fathers, are outlined and discussed. Key issues of focus in this section include married fathers balancing economic provision, household work, and involvement in child rearing. Part two of the chapter will overview cultural challenges and contradictions facing mothers, particularly married mothers. The contradictory challenges often inherent in marriage-based mothering include the pressures too simultaneously provide "intensive mothering" and to be extensively involved in a career. In sum, the chapter will illustrate how married …

Self-Regulation As A Mediator Between Sibling Relationship Quality And Early Adolescents’ Positive And Negative Outcomes, Laura M. Padilla-Walker, James M. Harper, Alexander C. Jensen Phd
Faculty Publications
The current study examined the role of adolescents’ self-regulation as a mediator between sibling relationship quality and adolescent outcomes, after controlling for the quality of the parent-child relationship. Participants were 395 families (282 two parent; 113 single parent) with an adolescent child (M age of child at Time 1 = 11.15, SD = .96, 49% female) who took part in [project name masked for blind review] at both Time 1 and Time 2. Path analysis via structural equation modeling suggested that sibling affection was longitudinally and positively related to self-regulation and prosocial behaviors, and negatively related to externalizing behaviors; while …

Recent national surveys show that older youth who have experienced parental divorce tend to disengage from organized religion but feel as close to God as peers from intact families. In this paper, we offer a conceptual model and concrete guidelines to help adults engage in sensitive, yet direct, dialogues with older youth about the spiritual dimensions of parental divorce. Based on a recent line of empirical research on the role of religion and spirituality for post-divorce adjustment, we argue that parental divorce can be experienced as a spiritual trauma where the event is interpreted as a sacred loss and desecration, …

Using technology tools in math instruction can help stimulate problem-solving skills and understanding of math concepts. However, teachers need to be confident in their abilities to use technology tools. This study investigated whether or not a four-week in-service professional development institute that addressed the use of technology in math education helped improved the teachers’ attitude and confidence in applying technology. Findings indicated that as the teachers explored and used the available technology tools relevant to math instruction during the institute, the more proactive and motivated they became to continue their professional development in using technology for classroom instruction. They realized …

Environmental Correlates Of Abundances Of Mosquito Species And Stages In Discarded Vehicle Tires, Donald A. Yee, Jamie M. Kneitel, Steven A. Juliano
Faculty Publications
Discarded vehicle tires are a common habitat for container mosquito larvae, although the environmental factors that may control their presence or abundance within a tire are largely unknown. We sampled discarded vehicle tires in six sites located within four counties of central Illinois during the spring and summer of 2006 to determine associations between a suite of environmental factors and community composition of container mosquitoes. Our goal was to find patterns of association between environmental factors and abundances of early and late instars. We hypothesized that environmental factors correlated with early instars would be indicative of oviposition cues, whereas environmental …
The Effects Of Direct And Indirect Speech On Native English And Esl Speakers’ Perception Of Teacher Written Feedback, Wendy Baker, Rachel Hansen Bricker
The Effects Of Direct And Indirect Speech On Native English And Esl Speakers’ Perception Of Teacher Written Feedback, Wendy Baker, Rachel Hansen Bricker
Faculty Publications
This study explores how second language (L2) learners perceive indirect (hedging or indirect speech acts) and direct written teacher feedback. Though research suggests that indirect speech acts may be more difficult to interpret than direct speech acts (Champagne, 2001; Holtgraves, 1999), using indirect speech acts is often encouraged in the learning process, with the idea that it helps students discover their own errors (Ferris, 2007; Riley and Mackiewitz, 2003;). However, it may not be effective with L2 learners who often need more explicit instruction to understand how to revise their writing (Ferris, 2002). To examine the effect of different directness …
Acquiring The High Vowel Contrast In Quebec French: How Assibilation Helps, Wendy Baker, Laura Catharine Smith
Acquiring The High Vowel Contrast In Quebec French: How Assibilation Helps, Wendy Baker, Laura Catharine Smith
Faculty Publications
In Quebec French (QF), /t/ and /d/ are assibilated to [ts] and [dz] before /i/ and /y/, but not before /u/. Since the /y/-/u/ contrast is known to be difficult for English speakers learning French as a second language (L2), we examine whether L2 learners of French who have acquired the assibilation rule have any advantage in producing and perceiving the French /i/-/y/-/u/ contrast over L2 learners who produce less or no assibilation in their L2 French. Results demonstrate that L2 learners who are strong assibilators are better at producing vowels similarly to native QF speakers than weak assibilators, but …

The Impact Of L2 Dialect On Learning French Vowels: Native English Speakers Learning Que´Be´Cois And European French, Wendy Baker-Smemoe, Laura Catharine Smith
Faculty Publications
This article examines how a second language (L2) dialect affects how accurately the L2 is perceived and produced. Specifically, the study examined differences between the production and perception of French vowels /i/, /y/, and /u/ by learners of either Quebec French (QF) or European French (EF). These vowels differ across the two varieties, both acoustically and because of assibilation of /t-d/ before /i-y/ for QF versus EF. As a result of these differences, QF has an additional acoustic cue with which to contrast /u/ and /i-y/. Anglophone learners of QF or EF were asked to identify and discriminate both QF …

This study compared the amount of the second language (L2) use and linguistic gains made by students in three short‑term language immersion programs: (1) traditional study abroad, (2) service-oriented study abroad, and (3) foreign language (FL) housing. These were chosen because they represent three distinct program types, providing students with different ways of interacting in the target language and different types and amounts of contact with native speakers. This allowed us to evaluate relationships between study setting, language use, and language gains. Learners completed language logs detailing their use of the L2 as well as pre- and post-immersion oral tests …

Antecedents Of Supervisor Trust In Collectivist Cultures: Evidence From Turkey And China, S. Arzu Wasti, Hwee Hoon Tan
Research Collection Lee Kong Chian School Of Business
The premise of much research on dyadic trust building within organizations has been framed around the relationship as it emerges in the work context. Such models, including the seminal Mayer et al. (1995) model of dyadic trust, have been applied to contexts outside North America without a careful understanding of the distribution of social practices and everyday situations in such contexts. This chapter examines culture-specific workways as a starting point for understanding subordinates’ trust in their supervisors in collectivist cultures. Workways refer to the pattern of workplace beliefs, mental models and practices about what is true, good and efficient within …

The Employment Relationship, John W. Budd, Devasheesh P. Bhave
Research Collection Lee Kong Chian School Of Business
The employment relationship is the connection between employees and employers through which individuals sell their labor. This might consist of an immigrant day laborer paid by the bushel to pick fruit in the hot sun, a salaried manager who has been working in an air-conditioned office for the same company for 40 years, or innumerable other situations. Irrespective of situation, all employees and employers have fundamental interests they pursue through the employment relationship, all forms of this relationship are mediated by labor markets and states, and each instance of this relationship is governed by some form of a contract, ranging …

Romantic Relationships And The Physical And Mental Health Of College Students, Scott R. Braithwaite, Raquel Delevi, Frank Fincham
Romantic Relationships And The Physical And Mental Health Of College Students, Scott R. Braithwaite, Raquel Delevi, Frank Fincham
Faculty Publications
This study tested the hypothesis that, analogous to married individuals, college students in committed romantic relationships experience greater well-being than single college students. In a sample of 1,621 college students, individuals in committed relationships experienced fewer mental health problems and were less likely to be overweight/obese. There were no significant differences between groups in frequency of physical health problems. Examination of 2 models suggested that being in a committed romantic relationship decreases problematic outcomes largely through a reduction in sexual partners, which in turn decreases both risky behaviors and problematic outcomes. These results are discussed in the context of how …

Are Older Adults Less Or More Physiologically Reactive? A Meta-Analysis Of Age-Related Differences In Cardiovascular Reactivity To Laboratory Tasks, Wendy C. Birmingham, Bert N. Uchino, Cynthia A. Berg
Faculty Publications
In this meta-analytic review of 31 laboratory studies, we examined if relatively older adults showed lower or higher cardiovascular reactivity compared with relatively younger adults. Results revealed that age was associated with lower heart rate reactivity but higher systolic blood pressure (SBP) reactivity during emotionally evocative tasks. Consistent with the predictions of dynamic integration theory, the result for SBP was moderated by the degree of task activation. These data are discussed in light of existing self-regulatory models and important future research directions.

Married With Children: The Influence Of Parental Status And Gender On Ambulatory Blood Pressure, Wendy C. Birmingham, Julianne Holt-Lunstad, Adam M. Howard, Dustin Thoman
Faculty Publications
Background Although there is substantial evidence that social relationships and marriage may influence both psychological and physical health, little is known about the influence of children. Purpose This study examined the competing predictions regarding the directional influence of parental status and its interaction with gender—given that mothers are typically disproportionately more responsible for everyday care of children—on cardiovascular functioning. Method We examined ambulatory blood pressure (ABP) over 24 hours among 198 married males and females. Results Couples without children had significantly higher ambulatory SBP and DBP than those with children. Moreover, we found a significant interaction between parental status and …

The error-related negativity (ERN) and post-error positivity (Pe) components of the event-related potential (ERP) arerelatively stable over time. The current study further assessed the temporal reliability of ERN and Pe amplitudes forrandom samples of 2 to 14 trials per participant and the grand mean over a 2-week retest interval. In a replication ofprevious results, intraclass and zero-order correlations revealed moderate to good temporal stability for participants’(N520) grand mean ERN and Pe component amplitudes. Adding trials increased test–retest reliabilities; however, thetemporal stability of ERN and Pe amplitudes with 14 or fewer trials were modest at best and considerably lower thanthat for …
Is Regime Switching In Stock Returns Important In Asset Allocations?, Jun Tu
Is Regime Switching In Stock Returns Important In Asset Allocations?, Jun Tu
Research Collection Lee Kong Chian School Of Business
The stock market displays regime switching between upturns and downturns. This paper provides a Bayesian framework for making portfolio decisions that takes this regime switching into account, together with asset pricing model uncertainty and parameter uncertainty. The findings reveal that the economic value of accounting for regimes is substantially independent of whether or not model and parameter uncertainties are incorporated: the certainty-equivalent losses associated with ignoring regime switching are generally above 2% per year, and can be as high as 10%. These results suggest that the more realistic regime switching model is fundamentally different from the commonly used single-state model, …

On March 29, 1949, V.S. Naipaul was front-page news in the Trinidad Guardian. “Special ‘Schol’ Urged for QRC Student,” the headline stated, and beneath was a photo of a quietly smiling teenage Naipaul, looking studious and benign in a pair of large black-rimmed glasses (“Special”). Naipaul, the article reports, had earned marks of distinction in Spanish and French on the Cambridge Higher School Certificate Examination, but was not eligible for a Colonial Scholarship to study in England owing to a recently-introduced technicality. Through no fault of his own he had not completed all of the requisite course work to qualify …
