Description
The development of self-regulation is believed to play a crucial role in predicting later psychopathology and is believed to begin in early childhood. The early postpartum period is particularly important in laying the groundwork for later self-regulation as infants' dispositional traits interact with caregivers' co-regulatory behaviors to produce the earliest forms of self-regulation. Moreover, although emerging literature suggests that infants' exposure to maternal stress even before birth may be integral in determining children's self-regulatory capacities, the complex pathways that characterize these developmental processes remain unclear. The current study considers the complex, transactional processes in a high-risk, Mexican American sample. Data were collected from 305 Mexican American infants and their mothers during prenatal, 6- and 12-week home interviews. Mother self-reports of stress were obtained prenatally between 34-37 weeks gestation. Mother reports of infant temperamental negativity and surgency were obtained at 6-weeks as were observed global ratings of maternal sensitivity during a structured peek-a-boo task. Microcoded ratings of infants' engagement orienting and self-comforting behaviors were obtained during the 12-week peek-a-boo task. Study findings suggest that self-comforting and orienting behaviors help to modulate infants' experiences of distress, and also that prenatal stress influences infants' engagement in each of those regulatory behaviors, both directly by influence tendencies to engage in orienting behaviors and indirectly by programming higher levels of infant negativity and surgency, both of which may confer risk for later regulatory disadvantage. Advancing our understandings about the nature of these developmental pathways could have significant implications for targets of early intervention in this high-risk population.

The purpose of drinking water regulations is to keep our drinking water safe from contaminants. This research reviewed federal regulation including the Contaminant Candidate List (CCL) regulatory process, the public health effects of six nitrosamines in drinking water, analyzes of occurrence data from Unregulated Contaminant Monitoring Rule (UCMR 2) and suggests how nitrosamines can be regulated. Currently only total trihalomethanes (THM) and haloacetic acids (HA) are regulated at the federal level. However, California has notification action levels and Massachusetts has guidelines of 10 ng/L for nitrosamine concentration. Nitrosamine data collected under the UCMR 2 were analyzed to assess the occurrence and the effect of disinfectant type and source water type. The data showed that N-nitrosodimethylamine (NDMA) was detected in drinking water at concentrations higher than the minimum reporting level (MRL) of 2 ng/L. Four nitrosamines including N-nitroso-diethylamine (NDEA), N-nitroso-di-n-butylamine (NDBA), N-nitroso-methylethylamine (NMEA) and N-nitroso-pyrrolidine (NPYR) and very low detections. N-nitroso-di-n-propylamine (NDPA) was not detected in the sample analyses. NDMA was primarily detected in public water systems using chloramines other than chlorine.

Description
The major goal of the current study was to extend previous research on adolescents' gender stereotyping by assessing adolescents' academic, classroom regulatory behavior, and occupational gender stereotypes. This was done by creating new measures of academic and classroom regulation gender stereotypes. Using these measures, adolescents' gender stereotypes in core academic subjects, school in general, and classroom behavior were assessed. The coherence of adolescents' stereotypes was also examined. Participants were 257 7th grade students (M age = 12 years old, range 11-13 years old; 47% male. Students were administered surveys containing several measures of stereotyping. The results indicated that, for academic subjects, contrary to expectations, very few adolescents held traditional gender stereotypes; instead, most endorsed egalitarian views. Moreover, unexpected patterns emerged in which adolescents reported counter-traditional academic stereotypes. When sex differences were found in stereotyping patterns, they could be explained in part by ingroup bias. Approximately half of the students stereotyped classroom regulatory behaviors and occupations. Results provided support for the coherence of gender stereotypes such that students who stereotyped in one domain tended to stereotype in other domains. Strengths and limitations of the present study were discussed. Potentially important steps remain for research on the relation between academic gender stereotyping and academic performance.

Description
The purpose of this study was to examine whether maternal personality (i.e., Agreeableness and Conscientiousness) predicted maternal positive parenting (i.e., warmth/sensitivity and structure), and whether maternal parenting predicted children's regulation and sympathy and/or prosocial behavior. Additionally, the mediated effect of maternal warmth/sensitivity on the relation between maternal Agreeableness and children's regulation and the mediated effect of maternal structure on the relation between maternal Agreeableness and children's observed sympathy/prosocial behavior were investigated. Maternal personality was measured when children (N = 256 at Time 1) were 18 months old; maternal parenting was assessed when children were 18, 30, and 42 months old; children's regulation and sympathy/prosocial behavior (observed and reported) were assessed when children were 30, 42, and 54 months old. Mothers reported on their personality; maternal warmth/sensitivity was observed; maternal structure was observed and mothers also reported on their use of reasoning; mothers and caregivers rated children's regulation (i.e., effortful control [EC]) and regulation was also observed; mothers and fathers rated children's prosocial behavior; sympathy and prosocial behavior were also observed. In a path analysis, Conscientiousness did not significantly predict maternal warmth/sensitivity or structure at 30 months, whereas Agreeableness marginally predicted maternal warmth/sensitivity at 30 months and significantly predicted maternal structure at 30 months. Maternal warmth/sensitivity at 18 months significantly predicted 30-month EC, and 30-month maternal warmth/sensitivity significantly predicted 42-month EC. Maternal structure at 30 months significantly predicted 42-month observed sympathy/prosocial behavior. Maternal warmth/sensitivity at 42 months significantly predicted 54-month observed sympathy/prosocial behavior and marginally predicted 54-month reported prosocial behavior. Maternal structure and EC did not significantly predict reported prosocial behavior across any time point. EC did not significantly predict observed sympathy/prosocial behavior across any time point and maternal warmth/sensitivity at 18 and 30 months did not predict observed or reported sympathy/prosocial behavior at 30 or 42 months, respectively. Maternal Agreeableness directly predicted 30-month reported prosocial behavior and additional paths suggested possible bidirectional relations between maternal warmth/sensitivity and structure. Mediation analyses were pursued for two indirect relations; however, neither mediated effect was significant. Additional results are presented, and findings (as well as lack thereof) are discussed in terms of extant literature.

Description
Data has quickly become a cornerstone of society. Across our daily lives, industry, policy, and more, we are experiencing what can only be called a “data revolution” igniting ferociously. While data is gaining more and more importance, consumers do not fully understand the extent of its use and subsequent capitalization by companies. This paper explores the current climate relating to data security and data privacy. It aims to start a conversation regarding the culture around the sharing and collection of data. We explore aspects of data privacy in four tiers: the current cultural and social perception of data privacy, its relevance in our daily lives, its importance in society’s dialogue. Next, we look at current policy and legislature in place today, focusing primarily on Europe’s established GDPR and the incoming California Consumer Privacy Act, to see what measures are already in place and what measures need to be adopted to mold more of a culture of transparency. Next, we analyze current data privacy regulations and power of regulators like the FTC and SEC to see what tools they have at their disposal to ensure accountability in the tech industry when it comes to how our data is used. Lastly, we look at the potential act of treating and viewing data as an asset, and the implications of doing so in the scope of possible valuation and depreciation techniques. The goal of this paper is to outline initial steps to better understand and regulate data privacy and collection practices. Our goal is to bring this issue to the forefront of conversation in society, so that we may start the first step in the metaphorical marathon of data privacy, with the goal of establishing better data privacy controls and become a more data-conscious society.

Description
Dodd-Frank should be celebrated for its success in stabilizing the financial sector following the last financial crisis. Some of its measures have not only contained financial disaster but contributed to economic growth. These elements of Dodd-Frank have been identified as "clear wins" and include the increase of financial institutions' capital requirements, the single-point-of-entry approach to regulating financial firms, and the creation of the Consumer Financial Protection Bureau (CFPB). The single-point-of-entry strategy (SPOE), specifically, has done much to bring an end to the age of "too big to fail" institutions. By identifying firms that could expect to be aided in case of financial crisis, the SPOE approach reduces uncertainty among financial institutions. Moreover, SPOE eliminates the significant source of risk by establishing clear protocols for resolving failed financial firms. Dodd-Frank has also taken measures to better protect consumers with the creation of the CFPB. Some of the CFPB's stabilizing actions have included the removal of deceptive financial products, setting guidelines for qualified mortgages, and other regulatory safeguards on money transfers. Despite the CFPB's many triumphs, however, there is room for improvement, especially in the agency's ability to reduce regulatory redundancies in supervision and collaboration with other financial sector controllers. The significant strengths of Dodd-Frank are evident in its elements that have secured financial stability. However, it is important to also consider any potential to stifle healthy economic growth. There are several areas for legislative amendments and reforms in order to improve the performance of Dodd-Frank given its sweeping regulatory impact. Several governing redundancies now exist with the creation of new regulatory authorities. Special efforts to increase the authority of the Financial Sector Oversight Council (FSOC) and preserving the impartiality of the Office of Financial Research (OFR) are specific examples of reforms still needed to elevate the effectiveness of Dodd-Frank. In addition, Dodd-Frank could do more to clarify the Volcker Rule in order to ease banks' burden to comply with excessive oversight. Going forward, policymakers must be willing to adjust parts of Dodd-Frank that encroach too far on the private sector's ability to foster efficiency or development. In addition, identifying and monitoring areas of the legislation deemed "too soon to tell" will provide insight on the accuracy and benefit of some Dodd-Frank measures.

Description
The ability to regulate emotions, attention, and behavior develops early in life and impacts future academic success, social competency, behavioral problems, and psychopathology. An impairment in regulation is known as dysregulation. Past research shows that children of mothers with postpartum depression are more likely to show impairment in regulatory abilities. There is an established link in the literature between family support and maternal depression, which in turn can impact child behavior. However, further research is needed to explore the impact of family support on early childhood dysregulation in the context of maternal depression. Using a sample of 322 Mexican-American, mother-child dyads, two models were examined. Model one hypothesized family support would buffer the effects of maternal depression on child dysregulation at 24 months. Model 2 hypothesized that family support is related to child dysregulation through its effect on maternal depression. Results showed that increased family support was related to more child dysregulation when there were high levels of maternal depression. There was no evidence to support the hypothesis that maternal depression mediated the relationship between family support and child dysregulation.

Description
The field of study that this topic is derived from constitutes both federal aviation regulation as well as medical and biological sciences. The compelling idea of this thesis is an in depth investigation of the Federal Aviation Administration's (FAA) regulation and data collection throughout time regarding pilots with Insulin Treated Diabetes Mellitus (ITDM). When in comparison to the continuous evolution of diabetic research and endocrinology in all parts of the world, the regulations regarding this group of pilots seems displaced. This paper explores a chronological order of FAA research and regulations that were conducted on diabetic pilots stemming from 1959 - present. The findings seem to convey that the field of aviation is laden with inconsistencies and misplaced conclusions regarding regulation of insulin-treated diabetic pilots. This paper reflects on the impact of these regulations on this group of pilots from both a biological and medical standpoint as well as from an aviation point of view. In light of advanced medical knowledge, the paper explores what regulations regarding ITDM are in other countries and how FAA regulation should be refined and altered to realign with present day medical knowledge in the United States. This research was conducted to compare the sequential endocrinologic knowledge conducted and the subsequent regulatory actions.

Description
Non-photochemical quenching (NPQ) is a photoprotective regulatory mechanism essential to the robustness of the photosynthetic apparatus of green plants. Energy flow within the low-light adapted reaction centers is dynamically optimized to match the continuously fluctuating light conditions found in nature. Activated by compartmentalized decreases in pH resulting from photosynthetic activity during periods of elevated photon flux, NPQ induces rapid thermal dissipation of excess excitation energy that would otherwise overwhelm the apparatus’s ability to consume it. Consequently, the frequency of charge separation decreases and the formation of potentially deleterious, high-energy intermediates slows, thereby reducing the threat of photodamage by disallowing their accumulation. Herein is described the synthesis and photophysical analysis of a molecular triad that mimics the effects of NPQ on charge separation within the photosynthetic reaction centers. Steady-state absorption and emission, time-resolved fluorescence, and transient absorption spectroscopies were used to demonstrate reversible quenching of the first singlet excited state affecting the quantum yield of charge separation by approximately one order of magnitude. As in the natural system, the populations of unquenched and quenched states and, therefore, the overall yields of charge separation were found to be dependent upon acid concentration.
