Comparing Forward And Backward Chaining In Teaching Olympic Weightlifting, James W. Moore, Laura M. Quintero

Faculty Publications

The popularity of Olympic‐style weightlifting in fitness routines is growing, but participating in these exercises with improper technique places lifters at increased risk for injury. Fitness training professionals have developed multiple teaching strategies, but have not subjected these strategies to systematic evaluation, particularly with novice lifters. Two strategies recommended by professional training organizations are akin to forward and backward chaining, which have been shown effective at teaching other novel, complex behaviors. The present study compared these forward‐ and backward‐chaining‐like strategies to teach novice lifters “the clean” and “the snatch,” two Olympic weightlifting movements frequently incorporated into high‐intensity training programs. Participants …

The Search For Microbial Martian Life And American Buddhist Ethics, Daniel S. Capper

Faculty Publications

Multiple searches hunt for extraterrestrial life, yet the ethics of such searches in terms of fossil and possible extant life on Mars have not been sufficiently delineated. In response, in this essay I propose a tripartite ethic for searches for microbial Martian life that consists of default nonharm toward potential living beings, default nonharm to the habitats of potential living beings, but also responsible, restrained scientific harvesting of some microbes in limited transgression of these default nonharm modes. Although this multifaceted ethic remains secular and hence adaptable to space research settings, it arises from both a qualitative analysis of authoritative …

The Effectiveness Of Structured Coloring Activities For Anxiety Reduction, Laura E. Ashlock, Cindy Miller-Perrin, Elizabeth Krumrei-Mancuso

All Faculty Open Access Publications

This study compared the effects of 4 different coloring activities on state anxiety scores to determine whether adult coloring books are as effective as other coloring activities in reducing anxiety. Participants were 160 undergraduates attending a private, Christian, liberal arts university. After engaging in an anxiety induction activity, participants completed an anxiety inventory, engaged in an assigned coloring activity, and then completed the anxiety inventory again. Results indicated that all 4 conditions significantly reduced anxiety; however, none of the conditions differed significantly from each other in their effectiveness, suggesting that coloring books are as effective as other coloring activities in …

Reliability Of Mturk Data From Masters And Workers For Personality And Cognitive Abilities, Steven V. Rouse

All Faculty Open Access Publications

Previous research has supported the use of Amazon’s Mechanical Turk (MTurk) for online data collection in individual differences research. Although MTurk Masters have reached an elite status because of strong approval ratings on previous tasks (and therefore gain higher payment for their work) no research has empirically examined whether researchers actually obtain higher quality data when they require that their MTurk Workers have Master status. In two different online survey studies (one using a personality test and one using a cognitive abilities test), the psychometric reliability of MTurk data was compared between a sample that required a Master qualification type …

Clustering Attitudes And Behaviors Of High/Low Involvement Grocery Shopper, Ronald Conlin, Alice Labban

All Faculty Open Access Publications

The purpose of this exploratory and quantitative study was to examine the attitudes and behaviors of 14,807 grocery shop- pers. These respondents across the US were asked to answer attitudinal, behavioral, and demographic related questions. Shoppers were profiled by analyzing their responses to 16 relevant attitudinal and behavioral questions. A cluster analysis was performed followed by a discriminant analysis to deter- mine attitudinal and behavioral variables explaining cluster membership. A cross-tabulation analysis assessed demo- graphic variables that correlated with cluster membership. Two clusters were identified: high and low involvement grocery shoppers. In an event that has long been perceived as …

Perceptions Of Police-Civilian Encounters: Intergroup And Communication Dimensions In The United Arab Emirates And The Usa, Charles W. Choi Ph.D., Gholam Hassan Khajavy, Rana Raddawi Ph.D., Howard Giles

All Faculty Open Access Publications

This study investigates the impact of perceived police accommodation on police-civilian interactions. Elaborating theoretically beyond a range of cross-cultural studies, we examine the cultural impact of accommodative communication in the United Arab Emirates (UAE) and United States of America (USA), as the prior context demonstrates socio-cultural parallels and differences including the influence of Sharia law. Between-country comparisons evaluate the mediating role of trust, affect and intergroup orientation on various civic outcomes. Accommodative communication was the strongest predictor of trust for both nations and demonstrated a direct impact on moral alignment and willingness to help only in the UAE.

The Hermeneutics Of Policing: An Analysis Of Law And Order Technocracy, Jason Blakely

All Faculty Open Access Publications

Contemporary American policing practices are marked by increasingly top-down, racialized, militarized, and pseudo-scientific features. Social scientists have played a central role in creating this political situation: social-scientific advocates of “law and order,” far from providing a value-neutral description of social reality, appear instead to have contributed to the creation of a peculiarly modern form of power.

Vector Tick Transmission Model Of Spotted Fever Rickettsiosis, Tais Berelli Saito, Jeremy Bechelli, Claire Smalley, Shahid Karim, David H. Walker

Faculty Publications

Many aspects of rickettsial infections have been characterized, including pathogenic and immune pathways and mechanisms of rickettsial survival within the vertebrate host and tick vector. However, very few studies are focused on the complex pathogen–vector–host interactions during tick feeding. Therefore, our objective was to develop a tick transmission model of the spotted fever group of rickettsial infections to study the initial events in disease development. The most appropriate strain of mouse was identified for evaluation as a transmission model, and the course of infection, bacterial levels, histopathologic changes, and antibody response during tick transmission in mice infested with Amblyomma maculatum …

Periphytic Algae Decouple Fungal Activity From Leaf Litter Decomposition Via Negative Priming, Halvor M. Halvorson, Jacob R. Barry, Matthew B. Lodato, Robert H. Findlay, Steven N. Francoeur, Kevin A. Kuehn

Faculty Publications

1. Well‐documented in terrestrial settings, priming effects describe stimulated heterotrophic microbial activity and decomposition of recalcitrant carbon by additions of labile carbon. In aquatic settings, algae produce labile exudates which may elicit priming during organic matter decomposition, yet the directions and mechanisms of aquatic priming effects remain poorly tested.

2. We tested algal‐induced priming during decomposition of two leaf species of contrasting recalcitrance, Liriodendron tulipifera and Quercus nigra, in experimental streams under light or dark conditions. We measured litter‐associated algal, bacterial, and fungal biomass and activity, stoichiometry, and litter decomposition rates over 43 days.

3. Light increased algal biomass and …

Antecedents And Consequences Of Self-Congruity: Replication And Extension, Eugene Cheng-Xi Aw, Leisa Reinecke Flynn, Han Xi Chong

Faculty Publications

Purpose

The purpose of this study is to propose and empirically test a framework encompassing self-congruity with its antecedents and consequences. This study also aims to test the mediating role of perceived value and its dimensions.

Design/methodology/approach

A questionnaire-based survey was conducted using a purposive sampling technique. In total, 310 useable responses were collected and data were analyzed using partial least square structural equation modeling.

Findings

A majority of hypotheses were supported. Avoidance of similarity and status consumption positively influenced self-congruity, replicating an earlier study. Self-congruity positively influenced overall perceived value and its dimensions, as well as revisit intention. Overall …

A Proof-Of-Mechanism Study To Test Effects Of The Nmda Receptor Antagonist Lanicemine On Behavioral Sensitization In Individuals With Symptoms Of Ptsd, Marijn Lijffijt, Charles E Green, Nicholas Balderston, Tabish Iqbal, Megan Atkinson, Brittany Vo-Le, Bylinda Vo-Le, Brittany O'Brien, Christian Grillon, Alan C Swann, Sanjay J Mathew

Faculty, Staff and Students Publications

Background: Individuals with post-traumatic stress disorder (PTSD) have a heightened sensitivity to subsequent stressors, addictive drugs, and symptom recurrence, a form of behavioral sensitization. N-methyl-D-aspartate receptors (NMDARs) are involved in the establishment and activation of sensitized behavior.

Objective: We describe a protocol of a randomized placebo-controlled Phase 1b proof-of-mechanism trial to examine target engagement, safety, tolerability, and possible efficacy of the NMDAR antagonist lanicemine in individuals with symptoms of PTSD (Clinician Administered PTSD Scale [CAPS-5] score ≥ 25) and evidence of behavioral sensitization measured as enhanced anxiety-potentiated startle (APS; T-score ≥ 2.8).

Methods: Subjects (n = 24; age range 21–65) …

Reduction In Hospitals' Readmission Rates: Role Of Hospital-Based Skilled Nursing Facilities, Shivani Gupta, Ferhat D. Zengul, Ganisher Davlyatov, Robert Weech-Maldonado

Faculty Publications

Hospital readmission within 30 days of discharge is an important quality measure given that it represents a potentially preventable adverse outcome. Approximately, 20% of Medicare beneficiaries are readmitted within 30 days of discharge. Many strategies such as the hospital readmission reduction program have been proposed and implemented to reduce readmission rates. Prior research has shown that coordination of care could play a significant role in lowering readmissions. Although having a hospital-based skilled nursing facility (HBSNF) in a hospital could help in improving care for patients needing short-term skilled nursing or rehabilitation services, little is known about HBSNFs’ association with hospitals’ …

An Army Of One: Predaceous Diving Beetle Life History Stages Affect Interactions With Shared Mosquito Prey, Carmen E. Bofill, Donald A. Yee

Faculty Publications

Predators with complex life cycles often differ in their morphology, behavior, and trophic position across their ontogeny, and may thus have variable effects on shared prey. We used the predaceous diving beetle Laccophilus fasciatus rufus as our predator, whose larvae and adults often co-occur in freshwater lentic systems. As a shared prey we used early and late instar Culex quinquefasciatus, a common wetland mosquito. We found that single adult predators were more likely to consume late instar prey compared to juvenile predators, who ate early and late instar prey equally. A mixture of juvenile and adult predator stages led …

“It Takes A Village To Raise A Rigorous Qualitative Project”: Studying Family Financial Socialization Using Team-Based Qualitative Methods, Loren D. Marks, Christina M. Rosa, Ashley B. Lebaron, E. Jeffery Hill

Faculty Publications

This purpose of this case study is to relate the methods used to conduct a qualitative research project about family financial socialization designed by emerging adults, primarily employing emerging adults as the primary research participants (although some of their parents and grandparents are interviewed). A sample of 153 respondents (128 undergraduate students, 17 parents, and eight grandparents) at three universities was recruited to assure diversity. We outline and discuss our team-based approach to qualitative data collection, analysis, and coding procedures, as well as how a team of 10 undergraduate students was incorporated into this approach. We relate the challenges and …

In Advanced L2 Reading Proficiency Assessments, Should The Question Language Be In The L1 Or The L2?: Does It Make A Difference?, Troy L. Cox, Jennifer Brown, Teresa R. Bell

Faculty Publications

When investigating foreign language (FL) proficiency in reading in higher education, one must first determine what proficient reading entails and how to operationalize it. The American Council on the Teaching of Foreign Languages (ACTFL) proficiency guidelines provide a starting point in this process, but they do not provide instructions for assessing reading. Clifford and Cox (Foreign Lang Ann 46(1):45–61, 2013) define proficient reading as “the active, automatic, far-transfer process of using one’s internalized language and culture expectancy system to efficiently comprehend an authentic text for the purpose for which it was written (p. 50).” According to this definition, reading is …

Investigating The Use Of The Actfl Can-Do Statements In A Self-Assessment For Student Placement In An Intensive English Program, Troy L. Cox, Maria M. Summers, Benjamin L. Mcmurry, Dan P. Dewey

Faculty Publications

In this study, the authors use a validation framework to evaluate the usefulness of a self-assessment instrument based on the ACTFL Can-Do Statements for student placement in an Intensive English Program. The authors evaluated (a) the design of the instrument by investigating how well the intended item difficulties aligned with the actual item difficulties (ACTFL Proficiency Guidelines) and how well the scale functioned; (b) the assessment instrument itself through evaluating how reliably it distinguished between students with different levels of self-perception, and (c) the interpretation of scores that examined how well the results could be used as a proxy measure …

Constructing Meaning Through Connection: Religious Perspectives On The Purpose Of Life, Quinn Galbraith, Adam Callister, Heather Kelly

Faculty Publications

Given prior research, which establishes a connection between religiosity and an increased sense of meaning in life, this study draws on qualitative data from interviews with 172 religious individuals living in Ireland and the United Kingdom in order to analyze what religious individuals perceive as their purpose in life. Interviews were conducted in person, recorded, transcribed verbatim, and coded utilizing a team-based methodology. Researchers identified three main themes from the data related to the idea that the purpose of life is tied to relationships and connection: love and service toward others, family relationships, and connection with God. An analysis of …

Late-Career Unemployment Has Mixed Effects In Retirement, Wendy C. Birmingham, Maren Wright Voss, M Beth Merryman, Lisa Crabtree, Kathy Subasic, Lori Wadsworth, Man Hung

Faculty Publications

Paid work forms a pattern of occupational engagement that shifts during both unemployment and retirement. Similar to unemployment, the occupational disruption associated with involuntary retirement has been linked to poorer physical and mental health outcomes. To better understand the health impact of work transitions during the pre- and post-retirement years, 24 retired individuals with late-career unemployment were interviewed at the Huntsman World Senior Games in October 2016. Demographic data were collected. Braun and Clarke’s (2006) approach was utilized to thematically analyse the interview data and interpretations were evaluated against existing theory. Themes identified included struggle, freedom, and transition, followed by …

Associations Of Ambivalent Leadership With Distress And Cortisol Secretion, Wendy C. Birmingham, Raphael M. Herr, Frenk Van Harreveld, Bert N. Uchino, Adrian Loerbroks, Joachim E. Fischer, Jos A. Bosch

Faculty Publications

Ambivalent social ties, i.e., whereby a relationship is evaluated simultaneously in positive and negative terms, are a potential source of distress and can perturb health-relevant biological functions. Social interactions at the workplace, in particular with supervisors, are often described in ambivalent terms, but the psychological and psychobiological impact of such interactions has received little scientific attention. The current study examined associations between ambivalent attitudes towards one’s supervisor, perceived distress (general and work-related), and diurnal dynamics of the stress hormone cortisol. 613 employees evaluated their supervisor in terms of positive and negative behaviors, which was combined into an ambivalent index. Higher …

Spousal Influence: A Study Of Women With Eating And Body Image Concerns, Wendy C. Birmingham, Adriane Ito De Queiroz Cavallini, Jordan Sgro

Faculty Publications

Eating disorder literature often overlooks those exhibiting eating and body image concerns without an eating disorder diagnosis. Supportive spouses may ameliorate negative body image and eating behavior, but spouses who exhibit both supportive and non-supportive behaviors concurrently (ambivalent) may send mixed messages. Eating disorder behaviors and spousal interactions were assessed in 61 women who demonstrated eating disordered behavior and body dissatisfaction but were not clinically diagnosed with an eating disorder. Spouses mostly provided messages of reassurance. However, some women were unable to overcome their internalized negative body image. Feelings of social comparison were seen with ambivalent spouses. Supportive relationships may …

The Structure Of Competence: Evaluating The Factor Structure Of The Cognitive Therapy Rating Scale, Scott A. Baldwin, Simon B. Goldberg, Kritzia Merced, Derek D. Caperton, Zac E. Imel, David C. Atkins, Torrey Creed

Faculty Publications

The Cognitive Therapy Rating Scale (CTRS) is an observer-rated measure of cognitive behavioral therapy (CBT) treatment fidelity. Although widely used, the factor structure and psychometric properties of the CTRS are not well established. Evaluating the factorial validity of the CTRS may increase its utility for training and fidelity monitoring in clinical practice and research. The current study used multilevel exploratory factor analysis to examine the factor structure of the CTRS in a large sample of therapists (n = 413) and observations (n = 1,264) from community-based CBT training. Examination of model fit and factor loadings suggested that three within-therapist factors …

Designing And Developing An Online Self-Regulated Learning Course, Grant Eckstein, Mariah Krauel-Nix, Norman W. Evans, Benjamin L. Mcmurry

Faculty Publications

The concept of self-regulated learning has been a prominent topic in education and has been researched and applied to various educational fields. In the field of TESOL, self-regulation has been categorized into dimensions and linked with possible application tools to help ESL/EFL students better apply and develop related skills (Andrade and Evans 2013, 2015). Although these applications have seen some success, the administration of one intensive English program felt that its center's self-regulated learning program was ineffective for teachers and students. Therefore, curriculum designers evaluated the center's program, compiled data, and formed design specifications for an improved program. Their specifications …

Household Variation, Public Architecture, And The Organization Of Fremont Communities, James R. Allison, Katie K. Richards, Lindsay D. Johansson, Richard K. Talbot, Scott M. Ure

Faculty Publications

In the far-northern reaches of the greater American Southwest, diverse groups of small-scale agriculturalists, labeled “Fremont” by archaeologists, spread across the northern Colorado Plateau and eastern Great Basin. During the long history of Fremont archaeology, most projects have focused on the excavation of only one or a few residences even in large village sites. Until recently, there has been little effort to understand Fremont social organization or Fremont communities and nothing that could be called household archaeology (but see Hall 2008; Hockett 1998; Janetski and Talbot 2000, 2014; Simms 2008). In fact, for many years the prevailing view has been …

Verbs In Egyptian Arabic: A Case For Register Variation, Deryle W. Lonsdale, Michael G. White

Faculty Publications

The limited availability of Egyptian Arabic (EA) corpus resources, especially speech corpora, has left open opportunity for research into such dialect phenomena as register. In this paper we introduce a new two-millionword EA corpus, CALM. We perform a register analysis on EA between two subcorpora of CALM (i.e. Movies and Blogs), showing several features that vary between the two. A discussion follows about how annotation was carried out automatically, how it was handcorrected, and what the prospects are for carrying out similar studies using CALM.

Trading Regularity And Fund Performance, Jeffrey Busse, Lin Tong, Qing Tong, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

We construct a new measure of trading regularity, capturing the extent to which investors trade on a regular basis. Institutional investors that regularly trade outperform those that trade less regularly. The performance of funds that regularly trade persists for at least a year. Among those who trade most regularly, larger funds perform relatively worse, because they incur higher transaction costs associated with their larger trades. Institutions that regularly trade generate superior performance, in part, by behaving as contrarians and by trading more aggressively on information. By contrast, we find no relation between trading regularity and performance among index funds.
