Show moreUsing variables identified in the social science literature believed to influence attitudes toward seeking professional counseling, an attempt was made to develop a model for predicting Hispanics' willingness to obtain professional help. A second purpose of this study was to compare college students (n = 158) with their parents on their attitudes toward mental illness and toward seeking counseling. Among predictor variables, social stigma and the belief that mental illnesses are untreatable were the primary variables predicting attitudes toward seeking counseling. The more college students and their parents perceived there to be social stigma attached to those seeking therapy, and the more parents believed that mental illnesses are untreatable, the less favorable attitudes they had about seeking professional help. These attitudes were linked to their acculturation levels; in general, the more acculturated they were toward the Hispanic culture, the more pejorative their attitudes were toward mental illness and their willingness to seek professional help. Last, college students in general had significantly more positive attitudes toward mental illness and professional counseling than their parents. Recommendations for providing counseling with Hispanic clients are provided in the context of the present findings.

Show moreMosquitofish (Gambusia holbrooki) are native to the southeastern United States but invasive elsewhere, and are dominant predators in many ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I experimentally tested dispersal behavior of individual mosquitofish under a range of laboratory conditions relevant to field situations. Preliminary experiments showed that gender, lighting conditions, hunger and acclimation time did not significantly affect net dispersal rate. Power analysis based on this preliminary experiment determined that 6 replicate fish were sufficient for each subsequent experiment; I used 24 fish, and each fish was tested one time. Three factors that potentially could affect net swimming rate were tested: habitat of origin (permanent vs. temporary waters), water depth (3-24 mm), and the interaction between water depth and leaf litter type (upland and wetland). Fish from a temporary pond dispersed significantly faster than fish from a permanent pond, and fish dispersed significantly faster in deeper water than in shallower water. However, leaf litter significantly inhibited fish dispersal at all depths tested. Based on these experiments, G. holbrooki disperse more readily through relatively open and deeper (several centimeters) pathways between habitats such as roadside ditches, drainage canals and trails in flooded conditions. My results are useful for understanding mosquitofish dispersal behavior based on the abiotic and biotic factors examined in this experiment. I predict that mosquitofish can spread from a point of introduction at about 800 m per day, given and unobstructed path of only > 6 mm depth.

Firstly we conducted a primary study to test the effects of skin tone on service provider quality. The results showed that while skin tone had little effect, gender and ethnicity were more indicative. Therefore our study seeks to re-test the relationship between skin tone and consumer service perception as well as the effects of ethnicity and tipping behavior, and if a consumer's cultural identity strength plays a role in consumer perception. We examined the differences across ethnicities i.e. White, Hispanic, and African American. Specifically we were interested in any potential differences across skin tone (light skinned vs. dark skinned) within African American and Hispanic service providers. Firstly we sought out stock images that portrayed easily identifiable ethnicities. We exposed the respondents to those images in which we asked them to identify the ethnicity of the image as a manipulation check for ethnicity. In the actual study, all respondents were given the same service scenario with the image of one of the ten (White, light or dark skinned Hispanic, light or dark skinned African American, male or female) stock photos. Respondents were asked to rate the service quality, satisfaction, and tip amount. The data was analyzed as a 2 way independent-groups design.

Through this reliance, infants develop an attachment to their caregivers, thus setting the stage for how a child comes to view the world and the people in it. This study sought to further explore attachment behaviors through observation of a voluntary parent education course offered through the Early Learning Coalition of Orange County. Data were collected three times over the course of the nine week program on four mother-infant dyads. Across the three mothers who were present for at least two observations, negative behaviors decreased between the first and final observations; however, positive behaviors were observed, but less conclusive. The results of this study can be used to improve the current early intervention program, as well as those in the future.

Show moreErotic stimuli in the consumer's environment can lead to affective responses, which produce traits such as erotophobia-erotophilia and lovestyle. Individuals can be classified as one of six main lovestyles, as well as erotophilic (having a positive view towards sexual behaviors) or erotophobic (having a negative view towards sexual behaviors). A person's style of loving may affect which products he or she perceives to be helpful in attracting potential sexual and relationship partners. I investigated this possible correlation by examining (1) whether each lovestyle is erotophilic or erotophobic and (2) which products erotophilic individuals are more likely to buy as opposed to those that erotophobic individuals are more likely to buy in (a) attracting sexual partners and (b) attracting relationship partners. The study indicated that lovestyle did not predict erotophobia-erotophilia, nor did the erotophobia-erotophilia trait predict which products an individual bought. However, a significant relationship was found between gender and erotophobia-erotophilia, as well as between gender and many of the products. Overall, the findings suggest that gender is the biggest predictor of what products were perceived as helpful in attracting sexual and relationship partners.

Show moreBackground: Autism spectrum disorders (ASD) are a group of complex developmental disabilities which can cause behavior, social, and communication deficits. Anti-psychotic medications are often prescribed when symptoms such as aggression, irritability, hyperactivity, tantrums, and self-injurious behavior occur. Objective: To determine if anti-psychotic medications improve the behavior, social, and communication symptoms associated with ASD in children and adolescents. Search Strategy: Electronic literature searches were performed to find relevant studies and utilized the (1) Cochrane Database of Systematic Reviews, (2) Hispanic American Periodicals Index, (3) Medline, (4) PAIS International, (5) ProQuest Dissertations and Theses, (6) PsycInfo, (7) PubMed, (8) Springer LINK, (9) Taylor and Francis Journals, and (10) Sage Premier. Selection Criteria: Randomized controlled trials (RCTs) or quasi-experimental design (QED) studies of any dose of an anti-psychotic medication compared to a placebo or other prescription drug, in participants with autism spectrum disorder. Data Collection and Analysis: All studies which met the full-text level criteria were reviewed by a third party to validate the decision of inclusion. Meta-analyses in this review implemented both random and fixed-effects models. Main Results: Ten RCTs were included. Six studies evaluated a drug versus a placebo and four studies investigated the effects of two separate anti-psychotic medications or the efficacy of an additive medication to a drug and placebo group. Author's Conclusions: Limited evidence suggests the effectiveness of anti-psychotic medications in treating the behavioral symptoms associated with autism; however, further research is needed to determine the implications of long-term use.

Show moreChildhood maltreatment is an experience that is likely to have lasting effects on individuals' emotional and behavioral functioning throughout their lifetimes. In particular, childhood maltreatment often is implicated in the etiology of numerous unfavorable psychological outcomes. Other research also suggested that there is a relationship between child maltreatment and the style of attachment that individuals exhibit post-abuse. Lastly, an association exists between individuals' attachment styles and their emotional and behavioral functioning. Despite substantial documentation of these relationships, few studies examine childhood maltreatment, attachment, and emotional and behavioral functioning collectively. As a result, this study examined the relationships among childhood maltreatment, attachment relationships, and later emotional and behavioral functioning, including eating behaviors. In addition, this study examined the role that attachment serves in the relationship between child maltreatment and later functioning. One hundred participants completed five questionnaires assessing experiences of childhood maltreatment, attachment relationships, emotional and behavioral functioning, and eating behaviors. Results of this study indicated that those individuals who report childhood maltreatment are more likely to report unfavorable emotional and behavioral functioning, whereas those who report childhood maltreatment but who exhibit a secure attachment style to either a parent or a peer are less likely to exhibit unfavorable emotional and behavioral functioning. Further, both the experience of childhood maltreatment and attachment were significant predictors of individuals' emotional and behavioral functioning. Finally, attachment contributed unique significant variance to the relationship between childhood maltreatment and emotional and behavioral functioning, particularly participants' internalizing and total problems. Such findings suggested that secure attachment may serve as a protective factor against problematic emotional and behavioral symptoms as children reach emerging adulthood, even when individuals have had childhood maltreatment experiences earlier in their lives. The importance of studying the relationships among these variables is discussed.

Show moreIt is estimated that approximately 25% of women and 7.6% of men report experiencing violence from their romantic partner during their lifetime. Additionally, in households where interpartner violence occurs, there are between 3.3 and 10 million children in the United States alone. It is important to understand the cycle of domestic violence that can occur, as it can inform us about expected outcomes across time. This study examined mothers' childhood exposure to their own parents' domestic violence. It was hypothesized that childhood exposure to domestic violence would be related to unhealthy intimate relationships and to the development of maladaptive parenting behaviors during adulthood. These experiences also were hypothesized to be related to the behaviors of the mothers' young children. For this study, 133 mothers with children who ranged in age from 1(&)#189;- to 5-years participated. Results indicated that exposure to domestic violence in childhood was related significantly to the likelihood of experiencing interpartner violence later in life. Also, having a personal history of interpartner violence in adulthood was related to higher rates of internalizing and externalizing behavior problems in mothers' young children. Further, findings demonstrated a relationship between mothers' parenting behaviors and behavior problems in their children. Future research is needed to investigate further the mediators and moderators in the relationship between mothers' childhood exposure to domestic violence and behavior problems in their young children to broaden the literature on this topic. This information may be critical for treatment planning and intervention development for families who experience domestic violence.

Show moreThe current study leveraged the stressor-emotion model of CWB, the reflective-impulsive model of behavior, and theories of explicit and implicit personality to investigate the roles explicit and implicit aspects of personality, and work stressors have in influencing CWB. The stressor-emotion and reflective-impulsive models suggest that in addition to reflective (i.e., explicit) processes, impulsive (i.e., implicit) processes may also influence CWB because the act can be motivated by negative emotions induced by frustrating working conditions. Theories of personality and motivation suggest that conscientiousness, agreeableness, and emotional stability predict CWB because these traits motivate people to pursue goals that reduce or increase acts of CWB. Explicit and implicit theories of personality suggest that explicit aspects of personality should predict CWB driven by explicit processes, whereas implicit aspects of personality should predict CWB driven by implicit processes. These ideas were tested by examining explicit and implicit conscientiousness, agreeableness, and emotional stability as predictors of CWB, by examining implicit personality's incremental prediction of CWB over explicit personality, and by examining the interactions between implicit personality and work stressors as predictors of CWB. A series of hierarchical regression analyses were conducted using online survey data from 194 participants. The results of this study suggest that CWBs can be influenced by both explicit and implicit aspects of personality; however, in contrast to explicit personality, implicit personality is most likely to influence CWB when individuals experience a high level of work stressors.

Show moreMg-based metal matrix nanocomposites (MMNCs) with mechanical properties, superior to those of coarse-grained composites, are promising structural materials for applications in the automotive and aerospace industries. The research in this area was primarily focused earlier on either micro-scaled reinforcements or nano-scaled reinforcements with very low volume fractions. MMNCs with high volume fractions have not been explored yet. In this research, we study the processing, microstructures and properties of MMNCs containing ceramic nanoparticles up to 30 vol.%.We first investigated the mechanical alloying of Al2O3 nanoparticles and pure Mg under high-energy ball milling conditions. The phase evolution and their distribution were evaluated as a function of milling time. Then, the thermal stability of the formed nanocomposites was investigated by annealing it at high temperatures. It indicated that an exchange reaction had occurred to a large extent between Mg and Al2O3 resulting in the formation of Al and MgO phases. Additionally, the reaction between Al and un-reacted Mg led to the formation of Mg-Al intermetallics.Due to the reaction between Mg and Al2O3 during the milling and annealing process, we attempted to synthesize Mg/SiC nanocomposites. The mixed powders containing 0, 5, 10 and 15 vol.% SiC were produced by high energy ball milling and then the powders were consolidated via spark plasma sintering. The phase constitutions and microstructures of the Mg/SiC nanocomposites were characterized. SiC nanoparticles (average particle size ~14 nm) appear to be homogeneously dispersed within the matrix, and the average inter-particle spacings of all the Mg/SiC nanocomposites were smaller than 50 nm. Microscopic methods, even at high magnifications did not reveal any significant porosity in the as-processed MMNCs.Mechanical characterization of the Mg/SiC nanocomposites was conducted using the microindentation test. Besides the microhardness test, different intermediate pause times and loading rates were used to evaluate the stiffness and loading rate sensitivity of our samples. The abnormal microhardness and loading rate sensitivity were showed for the Mg-15 vol.% SiC samples. At the same time, the monotonic increase of stiffness with volume fraction was exhibited in the Mg/SiC nanocomposites.Finally, we investigated the quasi-static and dynamic response of Mg/SiC nanocomposites and microcomposites, and discussed the underlying mechanisms. Strain softening was noticed in the milled Mg sample under quasi-static compression. Similarly, the strengthening effect leveling off was also observed in the Mg-15 vol.% SiC samples under either quasi-static or high-strain rate uniaxial compression conditions. No significant plastic deformation was observed in the Mg/SiC nanocomposites. The estimated strain rate sensitivity of all the Mg/SiC nanocomposites in this work was around 0.03, which is much smaller than 0.3 and 0.6, observed for 100 nm and 45 nm grain size pure Mg individually. In particular, the existing models fail in predicting the inverse volume fraction effect, and other mechanisms are yet to be explored. The presence of SiC nanoparticles may play an important role that leads to this difference.

Show moreThe purpose of this quantitative research was to examine the level of implementation of School-wide Positive Behavior Support (SWPBS) in the State of Florida. The relationship between the fidelity of implementation of SWPBS as measured by the Benchmarks of Quality tool to academic and behavioral outcomes for middle and elementary schools was then analyzed. The academic outcomes for this study included FCAT Reading and Mathematics subtest scores. The behavioral outcomes were measured using the number of Office Discipline Referrals per 100 students and the number of days for Out of School Suspensions per 100 students. The literature review suggests that many outcomes have been associated with implementation of SWPBS. These include a reduction in ODRs and OSS days, increased academic achievement, increased instructional time, decreased administrative time addressing discipline, increased teacher satisfaction, improved peer relationships, and an increase in perceived school safety (Muscott, Mann,& LeBrun, 2008; Lassen, 2006; Landers, 2006; Lassen, Steele, & Sailor,2006; & Luiselli, Putnam, Handler, & Feinberg, 2005). The results of this study found that SWPBS is being implemented with fidelity in the majority of schools in one year and that these schools maintain or increase fidelity over time. Findings also suggest that there may be a relationship between greater implementation and lower ODR and OSS rates and to a lesser extent, academic outcomes. This research adds to the knowledge base regarding SWPBS implementation fidelity and its relationship to academic and behavioral outcomes and may be of use to policy makers, practitioners, and future researchers.

Show moreAs the effects of global climate change become increasingly apparent, many concerned individuals are making efforts to reduce their greenhouse gas emissions. One simple and effective method of reducing oneÃ‚Â's personal carbon footprint is through energy conservation behavior. Studies have shown that occupant behavior can control as much as 50% of residential energy use and that energy use varies widely between residences with the same number of occupants depending on consumption behavior. In light of this, energy conservation behavior is a valuable method of reducing greenhouse gas emissions and curbing the effects of climate change. Motivating people to conserve energy could have profound positive effects on the environment. The following study applies Icek AjzenÃ‚Â's Theory of Planned Behavior (1991) to energy conservation behavior among college students in the state of Florida. This research tests the hypothesis that pro-environmental attitudes, influence of peers, and a high level of perceived control over behavior have a significant impact on energy conservation behavior.

Title: The Impact of Judo on Aggressive Behaviors in Youth with Autism Spectrum Disorder.
Creator: Rivera, Paola, Garcia, Jeanette, Fukuda, David, Stout, Jeffrey, University of Central Florida
Abstract / Description: The aim of this study was to examine the effects of an 8-week judo program on lifestyle habits and behavior in children with Autism Spectrum Disorder (ASD). METHODS: Participants included 25 children (ages 8-17), with a formal diagnosis of ASD. The sample participated in an 8-week judo program (45 minutes, 1x week), with measures taken at baseline and at the end of the 8-weeks. In order to assess activity levels and sleep quality, participants were instructed to wear Actigraph GT9X...
Show moreThe aim of this study was to examine the effects of an 8-week judo program on lifestyle habits and behavior in children with Autism Spectrum Disorder (ASD). METHODS: Participants included 25 children (ages 8-17), with a formal diagnosis of ASD. The sample participated in an 8-week judo program (45 minutes, 1x week), with measures taken at baseline and at the end of the 8-weeks. In order to assess activity levels and sleep quality, participants were instructed to wear Actigraph GT9X Accelerometers for 7 days and nights. In order to assess behavioral changes, parents were given the ABC survey to fill out at baseline and post-intervention. Non-parametric paired t-tests were conducted to compare differences in behaviors, MVPA, SB, and sleep quality (i.e. sleep efficiency, total sleep time, number of awakenings, and wake after sleep onset) pre and post judo. RESULTS: Results indicated there was a strong negative correlation (r= -0.632) with inappropriate behaviors and the number of classes attended. Participants also spent a significantly greater percentage of time in daily MVPA (8% vs 4%, p=0.05) following the program. There was a significant increase in total minutes of sleep duration (572.56 vs 333.8, p=0.008) following the program, and although not statistically significant, a trend existed for improved sleep efficiency (92% vs 88%, p=0.1). CONCLUSION: Despite no significant differences in ABC scores pre and post-judo, a strong association between class attendance and lower ABC scores were observed, along with improvements in MVPA and sleep quality. Future studies should include larger samples of youth with ASD, over a longer intervention period.

Title: Employee Engagement, Job Attitudes, and Work Behavior: A Meta-Analytic Test of the Incremental Validity of Employee Engagement.
Creator: Koenig, Nick, Fritzsche, Barbara, Joseph, Dana, Bowers, Clint, Roth, Colin, University of Central Florida
Abstract / Description: Although the commercially-popular construct of employee engagement has gained attention in scholarly work in recent years, several questions about the construct remain unresolved. In the current paper, I addressed several issues with previous engagement research by (a) meta-analyzing the relationship between employee engagement, task performance, contextual performance, absenteeism, and turnover, (b) using these meta-analytic estimates to fit a series of models in which engagement predicts...
Show moreAlthough the commercially-popular construct of employee engagement has gained attention in scholarly work in recent years, several questions about the construct remain unresolved. In the current paper, I addressed several issues with previous engagement research by (a) meta-analyzing the relationship between employee engagement, task performance, contextual performance, absenteeism, and turnover, (b) using these meta-analytic estimates to fit a series of models in which engagement predicts both specific and broadly-defined work behaviors, and (c) estimating the unique predictive validity of engagement above and beyond job attitudes. Several regression equations and structural equation models were tested using a combination of previous meta-analytic correlations (k = 95) and original meta-analytic correlations (k = 12). Results of the study found that engagement does offer unique incremental validity over several work-related behaviors (task performance, ?R2 = .037; contextual performance, ?R2 = .025; turnover, ?R2 = .083), however this incremental validity has been over-stated in previous research. Results also found that the A-factor (higher order attitudinal construct) is strongly related to behavioral engagement (higher order behavioral construct) (? = .62) suggesting that when attitudes and behaviors are examined on the same level of specificity there is a strong predictive relationship between the two. These results suggest that although engagement may not be as unique as previous research has implied it does offer utility in the sense that it acts as a proxy for the A-factor.
