College and career readiness is an essential element in the success of students post high school; predicting how successful a high school student will be in a post-secondary setting is the focus of substantial research. Many tools and methods exist for predicting a student's readiness for college and career; unfortunately, gaps persist between readiness rates of different groups of students. The purpose of this study is to examine diagnostic data generated by an innovative survey tool to determine the relationship between high school students in ninth and tenth grades and their self-assessments of five subscales measuring college readiness. Using extant data collected by the Educational Policy Improvement Center as part of the CampusReady tool, this study uses basic descriptive and inferential statistics to look for differences between groups. Results suggest significant differences in the way that students from certain populations (students whose parents have completed differing levels of education, economically disadvantaged students, and Hispanic students) self-evaluate key college readiness skills. Findings from this study will inform K-12 practitioners who plan/develop college and career readiness programs. The impact of student self-reporting of college and career readiness has implications for future studies that aim to integrate college and career readiness programs.

The Wielandt subgroup, the intersection of normalizers of subnormal subgroups, is non-trivial in any finite group and thus gives rise to a series whose length is a measure of the complexity of a group's subnormal structure. Another measure, akin to the nilpotency class of nilpotent groups, arises from the strong Wielandt subgroup, the intersection of centralizers of nilpotent subnormal sections. This thesis begins an investigation into how these two invariants relate in finite soluble groups. ¶ Complete results are obtained for metabelian groups of odd order: the strong Wielandt length of such a group is at most one more than its Wielandt length, and this bound is best possible. Some progress is made in the wider class of groups with p-length 1 for all primes p. A conjecture for all finite soluble groups, which may be regarded as a subnormal analogue of the embedding of the Kern, is also considered.

The purpose of the quantitative study was to determine if there was a significant difference in the academic performance of students at the elementary level who loop compared to those who do not. This study also assessed if there was a significant difference in academic achievement among subgroups in students who loop compared to those who do not. A quantitative, ex post-facto, comparative design was used to analyze data to determine if there is a signficiant relationship between looping and academic achievement for elementary students. The scores of students enrolled in two looping classrooms at two schools were compared to those of two nonlooping classrooms at two schools. The data that were analyzed included students’ reading scores on the Developmental Reading Assessment (DRA), math benchmark scores, and a district writing assessment. The results of the quantitative study revealed that students who participated in looped classrooms scored significantly higher on the math benchmark than students who participated in nonlooped classrooms. However, there was no significant difference in reading or writing benchmark scores between students who participate in looped classrooms compared to students who participated in nonlooped classrooms. The results also revealed that there was a significant difference in writing scores between males and females in nonlooped classrooms, with females scoring significantly higher than males. However, there was no significant difference in writing scores between males and females in looped classrooms. In addition, no significant difference was found between males and females in looped and nonlooped classrooms in either reading or math scores. Finally, there was a significant difference in math scores between minority and nonminority students in nonlooped classrooms, with nonminority students scoring significantly higher than minority students. However, there was no significant difference in math scores between minority and nonminority students in looped classrooms. In addition, no significant difference was found between minority and nonminority students in looped and nonlooped classrooms in either reading or writing scores.

Religious nonaffiliates who have high certainty in the existence of God or a higher power (theistic nones) have grown rapidly in size in the U.S. in the last 30 years, and are now the fourth largest American religious or secular category. This subgroup has been overlooked in prior research on religion, secularism, and health. We build on recent work on religion and health by distinguishing between atheists, agnostics, and nonaffliliated theists when examining the link between religious or secular identification and self-rated health. Specifically, we advance research on the heterogeneity of secular individuals and health by splitting nonaffiliated theists into two subgroups: those who report certainty in their beliefs about God or some higher power (i.e., theistic nones), and those who are less certain about their beliefs in God (i.e., doubting nones). We analyze 13 waves (1988–2018) of pooled data (N = 15,349) from the General Social Survey (GSS), a large, recurring, and nationally-representative sample of U.S. adults conducted on a periodic basis. Using the GSS, we assessed self-rated health across religious and secular categories in a well-controlled model. When compared with conservative Protestants, theistic nones and atheists had significantly higher levels of self-rated health, whereas agnostics and low-certainty nonaffiliated theists (doubting nones) did not report significantly higher levels of self-rated health. This study adds to previous research by differentiating between theistic and doubting nones among nonaffiliated theists in relation to overall health differences. The results suggest that the level of certainty in beliefs about God or a higher power are an important factor among religious nones for predicting health outcomes. These findings highlight the necessity of analyzing heterogenous subgroups within secular populations in studies of health and well-being.

The main goal of this work is to examine classes of finite groups in which normality, permutability and Sylow-permutability are transitive relations. These classes of groups are called T , PT and PST , respectively. The main focus is on direct products of T , PT and PST groups and the behavior of a collection of cyclic normal, permutable and Sylow-permutable subgroups under the intersection map. In general, a direct product of finitely many groups from one of these classes does not belong to the same class, unless the orders of the direct factors are relatively prime. Examples suggest that for solvable groups it is not required to have relatively prime orders to stay in the class. In addition, the concept of normal, permutable and S-permutable cyclic sensitivity is tied with that of Tc, PTc and PSTc groups, in which cyclic subnormal subgroups are normal, permutable or Sylow-permutable. In the process another way of looking at the Dedekind, Iwasawa and nilpotent groups is provided as well as possible interplay between direct products and the intersection map is observed.

In a 9-month prospective study, sleep and daytime functioning were compared in a community sample of 86 participants aged 25-50 years: 43 meeting DSM IV criteria for primary insomnia (26 women & 17 men); and 43 controls (32 women & 11 men). Assessments were conducted at baseline, 4 and 8 months, and included: the Pittsburgh Sleep Quality Index; Spielberger StatefTrait Anxiety Inventory; Eysenck Personality Questionnaire, Beck Depression Inventory; Fatigue Severity Scale; SF-36; Epworth Sleepiness Scale; Dysfunctional Beliefs About Sleep Scale; Sleep Hygiene and Practices Scale, Sleep Disturbance Questionnaire and the Psychomotor Vigilance Task PVT. An instrument to assess the occupational consequences of insomnia (the Occupational Impact of Sleep Questionnaire; OISQ) was also developed in the course of the study. PWI versus control group comparisons were made with repeated measures multivariate ANOVAs. Differences were consistently and significantly maintained on measures of state (F = 15.85 P <0.001) and trait anxiety (F = 23.46; P < 0.001), depression (F = 18.37; P < 0.001), fatigue (F = 22.20; P < 0.001), and neuroticism (F = 11.09; P < 0.001). Among PWI, mental health (F = 14.04; P < 0.001), pain (F = 6.92; P < 0.001), role-emotion (F = 10.94; p < 0.001), general health perceptions (F = 4.77; P < 0.05), social functioning (F = 6.58; P < 0.01) and energy and vitality (F = 32.08; P < 0.001), on the SF-36, were consistent with inferior health related QoL. In addition, pre-sleep arousal (F = 14.76; P < 0.001), sleep hygiene (F = 35.26; P < 0.001) and sleep disturbance (F = 72.32; P < 0.001) were significantly worse within PWI. Subjectively reported TIB (F = 9.38; P < 0.01), SOL (F = 11.17; P < 0.01) and WASO (F = 21.10; P < 0.001), remained greater within PWI, with SE (F = 15.29; P < 0.001), TST (F = 9.38; P < 0.01) and subjective sleep quality (F = 29.57; P < 0.001) greater within controls. Data averaged over the duration of data collection (252 days) found PWI reported an average SOL >30 minutes, an average WASO of> 30 minutes, SE < 80%. Analysed in terms of night to night sleep quality, both PWI and controls showed a pattern of 'good' (sleep efficiency >80%) and 'poor' (sleep efficiency <80%) nights. However, the probability of individual poor nights remained consistently and significantly higher for PWI across the 9 months of the study. Actigraphy data failed to confirm between group differences in sleep, and correlation with diary measures was low in both groups. PVf performance showed instability. Significant group differences found at baseline, were no longer present at subsequent data collection points. Data support the inconsistency surrounding objective performance among PWI within the literature. However, the inconsistency can be attributed to greater change within control participant's performance, rather than within PWI. Data identified the existence of a stable subgroup of PWI reporting symptoms of daytime sleepiness. Daytime sleepiness was found to be a temporally stable feature for this sub-group of PWI, who also Showed a distinctive psychological profile compared to PWI who did not report daytime sleepiness. No difference, however, was observed in subjectively reported sleep structure, quality or daytime performance between these subgroups of PWI. Insomnia subgroup analyses suggest a trait-like difference between sleepy and non sleepy PWI.The OISO showed an acceptable level of internal consistency reliability (alpha 0.93); and successfully discriminated between PWI and controls. The OISO also showed consistent correlations with measures of global sleep quality and subjective sleep parameters. Expressed in terms of comparative percentage decrement, PWI showed a consistent 10% decrement in subjective occupational performance when compared with controls. The OISO shows that absenteeism and punctuality may not capture the full impact of insomnia on workplace performance.

More than half of known crime is committed by 5-6% of the criminal population. Who are these people? Research has shown that it is likely that a majority of these individuals are characterized by having a psychopathic personality. Interestingly, research has shown that psychopathic features are not unique to adults. Youths with high levels of psychopathic traits resemble adult psychopaths in that they are the most frequent, severe and aggressive, delinquent offenders. There is less knowledge, however, about the development of these traits in adolescence, and many fundamental questions have yet to be addressed. The aim of this dissertation is to begin to examine a few of these questions, such as: a) the role of parents andtheir behavior in the development of psychopathic personality in adolescence; b) patterns of stability and change in psychopathic traits during adolescence; and c) whether or not subgroups of adolescents with high levels of psychopathic traits can be identified in a normative community sample. Overall, the results reveal that a psychopathic personality profile characterizes a small group of youths at particular risk of negative development. This group, as well as showing high levels of psychopathic traits throughout adolescence, report high levels of delinquent behavior, and also experience dysfunctional relationships with their parents. Further, the results reveal important subgroups of adolescents with high levels of psychopathic traits, much in accordance with the literature on adult psychopaths. Whereas one group expresses the personality style of primary psychopaths, another is more aggressive, impulsive, and anxious than the other. Taken together, the results of this dissertation suggest that some adolescents are at particular risk of future negative development. Implications for theory and practice, and for the directions of future research, are discussed.
