Title: Narcissism, adjustment, and target-specific aggression in preadolescence: a test of the self-image failure hypothesis.
Creator: Pauletti, Rachel E., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: This study examined the consequences of self-image failure among narcissistic children. It was hypothesized that narcissistic children who perceive themselves as falling short of their hoped-for grandiose self (e.g., whose self-esteem is low) would not only increase over time in general aggression and decrease prosocial behavior, but also increase in the tendency to direct aggression specifically toward more socially successful peers (i.e., their putative rivals for social status)....
Show moreThis study examined the consequences of self-image failure among narcissistic children. It was hypothesized that narcissistic children who perceive themselves as falling short of their hoped-for grandiose self (e.g., whose self-esteem is low) would not only increase over time in general aggression and decrease prosocial behavior, but also increase in the tendency to direct aggression specifically toward more socially successful peers (i.e., their putative rivals for social status). Participants were 195 (101 boys) fourth through seventh-graders who were tested in both the fall and the spring of a school year. Results yielded some support for the hypotheses. Narcissism combined with low self-appraisals of the real self to predict decreases in prosocial behavior and increased aggression toward popular and attractive peers. These findings not only provide longitudinal evidence for the self-image failure hypothesis but also underscore the importance of a target-specific approach to investigating children's aggression.

Show moreThe present work uses statistical mechanics tools to investigate the dynamics of markets, prices, trades and wealth distribution. We studied the evolution of market dynamics in different stages of historical development by analyzing commodity prices from two distinct periods : ancient Babylon, and medieval and early modern England. We find that the first-digit distributrions of both Babylon and England commodity prices follow Benford's Law, indicating that the data represent empirical observations typically arising from a free market. Further, we find that the normalized prices of both Babylon and England agricultural commodities are characterized by stretched exponential distributions, and exhibit persistent correlations of a power law type over long periods of up to several centuries, in contrast to contemporary markets. Our findings suggest that similar market interactions may underlie the dynamics of ancient agricultural commodity prices, and that these interactions may remain stable across centuries. To further investigate the dynamics of markets, we present the analogy between transfers of money between individuals and the transfer of energy through particle collisions by means of the kinetic theory of gases. We introduce a theoretical framework of how micro rules of trading lead to the emergence of income and wealth distribution. Particularly, we study the effects of different types of distribution of savings/investments among individuals in a society and different welfare/subsidies redistribution policies. Results show that while considering savings propensities, the models approach empirical distributions of wealth quite well. The effect of redistribution better captures specific features of the distributions which earlier models failed to do. Moreover, the models still preserve the exponential decay observed in empirical income distributions reported by tax data and surveys.

Show moreCoral reefs worldwide are threatened by many environmental disturbances including harmful algal blooms (HABs) which have been increasing on Florida coasts over the past decade. Research has mainly focused on HAB identification, percent cover and other effects on the benthos but the relationship of HABs with upper trophic levels has received less attention. To study this relationship, a two-year investigation on a 10-m deep reef off of Hallandale Beach, was conducted. Stationary fish census coupled with benthic transect videos were conducted quarterly between April 2005-July 2007. A significant correlation between Lyngbya sp. blooms and alterations in fish assemblages was observed. Lyngbya had a negative interaction with fish species and abundance; additionally, HAB sample periods were significantly different from low algal abundance periods. Blooms of Dictyota sp. had no measurable relationship with the fish assemblage indicating HABs may have variable impacts on fishes depending on family, species and chemistry of the algae.

Title: Approaches for raising the level of FOXO3a in animal cells.

Show moreThe turtle is a unique model of anoxic survival. The turtle's brain can tolerate total oxygen deprivation for hours to days as well as prevent high levels of mitochondrial-derived free radicals upon re-oxygenation. Because of its ability to prevent elevated free radical generation, the turtle has also become recognized as a model of exceptional longevity. We are employing the turtle model for an investigation into the regulation of a key antioxidant enzyme system - methionine sulfoxide reductases (Msrs), primarily MsrA and MsrB. The Msr system is capable of reversing oxidation of methionines in proteins and Msr subtypes have been implicated in protecting tissues against oxidative stress, as well as, enhancing the longevity of organisms from yeast to mammals. Preliminary data, unpublished results, indicate that MsrA protein and transcripts are elevated by anoxia. A recent study on Caenorhabditis elegans demonstrated that FOXO is involved in activation of the MsrA promoter. Using the turtle MsrA promoter sequence we worked to determine which regions in the promoter are necessary for activation by anoxia. The results of the present study were 1) to prepare a TAT-FOXO3a fusion protein which could penetrate animal cells and 2) to construct a FOXO3a expression vector for transcription studies on MsrA expression.

Title: Attitude and valence dynamics in response to changes in perceived similarity vs. difference: implications for human conflict.
Creator: Michaels, Jay L., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description: Despite extensive research in conflict, relatively little is known about how psychological processes evolve over time in response to a dispute. The present research examines how cognitive and affective processes react to cooperative, competitive, or mixed cooperative-competitive interactions.

Show moreDespite extensive research in conflict, relatively little is known about how psychological processes evolve over time in response to a dispute. The present research examines how cognitive and affective processes react to cooperative, competitive, or mixed cooperative-competitive interactions. Experimental predictions were derived from a model of two-actor interaction (Liebovitch, Naudot, Vallacher, Nowak, Bu--Wrzosinksa & Coleman, 2008). Specifically, it was expected that attitudes and emotional valence would exhibit stable dynamics when people encountered a neutral, continually cooperative, or continually competitive interaction. However, attitudes and emotional valence were expected to exhibit perturbation in response to transitions from cooperation to competition and vice-versa. These predictions were tested in four experiments. The first study verified most predictions, finding that people have little attitude or valence reaction to interactions that are neutral, continually coo perative or continually competitive. This study also established that people's attitudes are significantly unstable when faced with an interaction shifting from cooperation to competition, and this is experienced with negative emotions. However, interactions shifting from competition to cooperation resulted in stable attitudes and emotional valence. The remaining three experiments sought to explain the lack of psychological reaction to the development of cooperation in a previously competitive interaction. In Study 2, interaction expectancy was ruled out as a factor. Study 3 demonstrated that the reactivity to sudden competition and lack of reactivity to sudden cooperation developed regardless of interaction history. Finally, Study 4 offers evidence indicating that the lack of reaction to sudden cooperation results from factors other than the duration of cooperative feedback. The research has several important implications. First, the results provide evidence that competition is, not necessarily a key factor in promoting heightened psychological reaction in conflict. Rather, transitions between peace and conflict likely hold greater influence on psychological processes in disputes. Furthermore, the experimental evidence provides the first empirical test of the model predictions and offers insight into how the model may be improved. By combining experimental results with the model, the research provides much needed information about how mental dynamics unfold and differ in response to cooperation versus competition.

Title: Attitudes and perspectives about backyard food gardening: a case study in South Florida.

As a result, city dwellers turned to commercial food market systems that import food from distant production areas.

Show moreAs cities grew throughout the past century, the availability of locally grown food declined, mostly because urban expansion occurred at the expense of adjacent agricultural land. As a result, city dwellers turned to commercial food market systems that import food from distant production areas. Private greenspace, which is one of the largest land cover types in cities, offers the potential for substantial agricultural production. Because urban food production on private land, such as backyards, requires the willing participation of landowners, resident's feelings about and experience with food growing are important to understand. The demographic groups that were most likely to food garden were those in long-term relationships, higher income brackets, those with college education and residents over 50 years old. Incentives and programs focused on producing more from existing gardens may be most appropriate for people in these demographic groups, while other groups will most require basic food growing information. Study participants highly valued intangible benefits of food gardening (e.g., relaxation, feelings of happiness and satisfaction), often more than the provision of food. Most barriers and problems with backyard food growing, such as a lack of space and the need for gardening information, were similar for those who food garden and those who do not. Results from this study indicate that traditional agricultural incentives and perspectives must be rethought if they are to be applied in urban settings. By creating incentives and initiatives that reflect the needs and challenges faced by urban growers, urban agriculture will become an integrated part of the community, improving food quantity and quality while enriching residents' lives.

In order to do this, an instrument was developed to measure attitudes towards bilingualism. No significant relations were found among education or ethnic identity and attitudes towards bilingualism in either group, but analyses revealed several other significant relationships. The two subscales of ethnic identity, MEIM-R Commitment and Exploration, were related to each other both within Asian and Latino groups and in all participants combined. In the combined sample, education levels of participants' mothers was correlated with the MEIM-R subscale of Exploration. In addition, participants with a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Commitment than participants with an Associates Degree or below. Participants with mothers who possess a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Exploration than participants with mothers who possess an Associates Degree or below. Finally, Asian participants were found to have lower levels of MEIM-R Commitment when compared to Latino participants.

Show moreThis one-year longitudinal study was designed to illuminate the direction of the causal arrow between children's perceptions of their mother's behavior and children's attachment style during a period of development that has been relatively neglected in research on attachment - preadolescence. The possibility that children's behavior problems moderate the influence of perceived parenting on attachment, or of attachment on perceived parenting, was also investigated. Participants were an ethnically diverse sample of 407 children (213 girls, 194 boys) who were in the fourth grade at initial testing (M age = 11 years 1 month). Measures included children's perceptions of five maternal behaviors (harassment, overprotectiveness, monitoring, affectionate contact, and reliable support), peer reports of children's behavior problems (internalizing and externalizing), and children's self-perceived attachment styles (preoccupied and avoidant). Contrary to a traditional attachment perspective, there was limited evidence that perceptions of parenting led to change in children's attachment styles. Though children with internalizing problems who perceived their mother as harassing developed preoccupied attachment over time, and children with externalizing problems who perceived their mother as v overprotective developed avoidant attachment over time. However, there was considerable support for the reverse causal hypothesis that children's attachment style influences how they perceive their mother: Preoccupied attachment predicted increasingly favorable perceptions of maternal behavior over time (reduced harassment and increased monitoring), whereas avoidant attachment predicted increasingly unfavorable perceptions of the mother over time (increased harassment, reduced monitoring, reduced affectionate contact, and reduced reliable support). Children's behavior problems moderated a few of these relations., Overall, results support a "child effects" interpretation of the links between perceived parenting and attachment styles during preadolescence.

Show moreSC-15 epoxy is used in many industrial applications and it is well known that the mechanical and viscoelastic properties of epoxy can be signicantly enhanced when reinforced with nanofillers. In this work, SC-15 epoxy is reinforced by loading with magnetically-active nanofillers and cured in a modest magnetic field. Because of the signicant magnetic response of the nanofillers, this is a low cost and relatively easy technique for imposing a strong magnetic anisotropy to the system without the need of a superconducting magnet. It is also found that this method is an effective way of enhancing the mechanical properties of epoxy. Three systems were prepared and studied. The first is a dilute system of various concentrations of Fe2O3 nanoparticles in SC-15 epoxy. The second system is a combination of Fe2O3 nanoparticles and chemically-functionalized single-walled carbon nanotubes (SWCNT(COOH)s) in SC-15 epoxy. The third is a dilute system of SWCNT(COOH)s decorated with Fe3O4 particles t hrough a sonochemical oxidation process in SC-15 epoxy. Samples have an initial cure of 6 hrs in a magnetic led of 10 kOe followed by an additional 24 hours of post curing at room temperature. These are compared to the control samples that do not have initial field curing. Tensile and compressive stress-strain analysis of the prepared systems shows that mechanical properties such as tensile strength, tensile modulus and compressive strength are enhanced with the inclusion of these nanofillers. It is also found that there is an anisotropic enhancement of these properties with respect to the imposed curing field. An interesting phenomenon is observed with the increase in modulus of toughness and fracture strain with nanotube inclusion., These parameters are drastically enhanced after curing the systems in a magnetic field. While there is a modest shift in glass transition temperature during viscoelastic analysis, the thermal stability of the created systems is not compromised. Results of these mechanical enhancements will be compared with other nanoloading techniques from literature.

Show morePeer aggression and bullying are significant problems for children in American schools. While a large body of research has been conducted in this area, none to date has examined the combined roles of temperament (behavioral activation system, or BAS, and behavioral inhibition system, or BIS), and empathy in predicting participation in bullying interactions. Previous research has found that low empathy facilitates aggressive behavior, while high empathy inhibits it, and has linked poor emotion regulation to conduct disorders. Thus, if these factors can predict behaviors towards peers, they may also predict (independently and in combination) involvement in bullying, specifically the roles assumed in those interactions - that is: bully, victim, bully-victim (a child who is both bully and victim), or defender/protector. The present study tested 226 middle school students on a measure of empathy (Interpersonal Reactivity Index), and a measure of temperament (BIS/BAS Scales). The students also completed a Peer Nomination Inventory to identify children who were aggressive toward others, victimized by peers, and/or protected peers from bullies. Although not all predictions were supported, results showed that certain sub-components of empathy, such as empathic concern (affective empathy) and personal distress (a measure of emotion regulation) predicted the behavior of "pure bullies" (bullies who are not themselves victimized), but not of other aggressive children such as bully-victims. High BAS drive and low BIS were significant predictors of aggressive behavior, and BAS reward responsiveness predicted protective behavior. Victimized children had higher fantasy (ability to identify with fictional characters) and lower perspective-taking (cognitive empathy) skills, and tended not to have overlapping characteristics and behaviors with protective children., These characteristics did not interact significantly with each other or with age, gender, ethnicity, or SES of students. It was concluded that pure bullies lack affective empathy, and victims lack cognitive empathy. That is, empathy is multidimensional and empathy deficits vary in type, but all lead to some form of socioemotional impairment. Furthermore, aggressive victims are a unique sub-group of children with unique characteristics.

These alternatives are based on post-Newtonian expansions that contain realistic gravitational waves. The first scheme is based on a second order post-Newtonian expansion in Arnowitt, Deser, and Misner transverse-traceless (ADMTT) gauge that has been re-summed to approach standard puncture data at the black holes.

The first scheme is based on a second order post-Newtonian expansion in Arnowitt, Deser, and Misner transverse-traceless (ADMTT) gauge that has been re-summed to approach standard puncture data at the black holes. The other schemes are based on asymptotic matching of the 4-metrics of two tidally perturbed Schwarzschild solutions to post-Newtonian expansions at different orders. The alternatives are encouraging and lead to quasi-circular orbits and show gravitational radiation from the onset, as well as a reduction of spurious radiation. Deficiencies compared to punctures include more eccentricity during inspiral and larger constraint violations, since the alternative data sets only approximate solutions of Einstein's equations.
