- Description:
- Measurements of two-particle correlation functions and the first five azimuthal harmonics, v(1) to v(5), are presented, using 28 nb(-1) of p + Pb collisions at a nucleon-nucleon center-of-mass energy of root s(NN) = 5.02 TeV measured with the ATLAS detector at the LHC. Significant long-range "ridgelike" correlations are observed for pairs with small relative azimuthal angle (|Delta phi| < pi/3) and back-to-back pairs (|Delta phi| > 2 pi/3) over the transverse momentum range 0.4 < p(T) < 12 GeV and in different intervals of event activity. The event activity is defined by either the number of reconstructed tracks or the total transverse energy on the Pb-fragmentation side. The azimuthal structure of such long-range correlations is Fourier decomposed to obtain the harmonics v(n) as a function of p(T) and event activity. The extracted v(n) values for n = 2 to 5 decrease with n. The v(2) and v(3) values are found to be positive in the measured p(T) range. The v(1) is also measured as a function of p(T) and is observed to change sign around p(T) approximate to 1.5-2.0 GeV and then increase to about 0.1 for pT > 4 GeV. The v(2)(p(T)), v(3)(p(T)), and v(4)(p(T)) are compared to the v(n) coefficients in Pb + Pb collisions at root s(NN) = 2.76 TeV with similar event multiplicities. Reasonable agreement is observed after accounting for the difference in the average p(T) of particles produced in the two collision systems.

- Description:
- Similar to the majority of communities in this country today, Fresno County has a problem regarding the delivery of protective services on behalf of abused children. It has been estimated that approximately 100,000 children are severely abused in the United States each year, a number which is twice the total of all children actually served by public and voluntary child welfare programs in the country in 1962, when the term "battered child syndrome" was coined. It is reliably reported that an average of two significant non-accidental injury cases in children occurs in Fresno each week.'1 The needs of the child and family in which battering occurs ere overwhelming. A cry for help, if unheeded, can result in a pathetic case of maiming, permanent disability, or death. Yet, in the face of these critical needs, it would appear that the response of the community has been at best fragmented and underproductive. The area of social work practice which traditionally has been concerned with the problem of child abuse is termed "protective services." The literature indicates that there have been many articles written, many theories formulated, and many diagnoses compiled regarding child abuse. But the crux of the matter lies in the problem of organization for effective delivery of services to this target population. There appears to be some question, moreover, regarding the role of social work in providing needed services to the abused child. The purpose of this study is to examine how a social service delivery system has historically developed into its present form in Fresno County. Specifically, this examination will encompass what has been done in regard to the organization for protective services on behalf of the battered child in this community. More generally, it shall describe the social work process of community involvement in establishing these protective services during the past decade. The contribution which this study is expected to make to social work practice is three-fold: (1) to provide an increase of knowledge regarding the historical development of a social service delivery system in response to a serious social problem, namely the problem of the abused child in Fresno County; (2) to extend systematic social work research from concern with agency-based social services analysis to consideration of the social work process which is involved in the development of a problem-centered delivery system; (3) to provide an impetus for community action to deliver social services more effectively to children and families in need of protection.

- Description:
- A revision of the bibliography, as well as an analysis on the data from the specimen labels of Scena propylea (Druce) (Erebidae: Arctiinae: Euchromiina) deposited in different scientific collections, was carried out and included information from 1894 to 2010. Its geographical distribution is restricted to the Trans-Mexican Volcanic Belt which determines this species as endemic. Data are provided on the biogeography, ecology and biology for this species. Its food plant is Thenardia floribunda (Apocynaceae) which is also endemic to Mexico. From this analysis, we propose the inclusion of both species in the document known as the Norma Oficial Mexicana 059 which encompasses the environmental protection of wild flora and fauna species native to Mexico and their risk categories, as well as the specifications for their inclusion, exclusion or change and a list of all species at risk.

- Description:
- During the World War II internment of Japanese and Japanese Americans, the internees published newspapers in each of the assembly centers and relocation camps. Both the government officials and internees used the center newspapers to disseminate different discourses and rhetoric throughout the interned population. The U.S. government officials in charge of the assembly centers used the newspapers to spread nationalist messages designed to coerce the internees into passive obedience with the relocation orders and used patriotic sentiments to appeal to the Japanese American internees. In the case of the internees, the newspaper articles and editorials published illustrate how the Japanese Americans dealt with internal conflict over their bicultural identity, conflict which stemmed from the disagreement over what tradition would be dominant in the centers, Japanese or American. The newspapers also demonstrate how the internees attempted to reach a delicate balance between these two clashing sides. The center newspapers create a new image of the relocation specifically exemplifying the diverse difficulties, disputes, and administrative oversight the internees dealt with throughout their relocation. This thesis will illustrate this point through articles and editorials from select assembly centers.

- Description:
- In forensic casework, liquid-liquid extractions are the most common technique used for drug evidence analysis and conditions are chosen by the analyst to best fit the type of evidence, instrumental conditions, legal requirements, and analysis criteria. The solvent polarity, type of aqueous modifier, and concentration of modifier used in an extraction scheme impact the solubility and extraction of the analytes. This work evaluated the dependence of extraction efficiency on solvent, modifier, and modifier concentration by using methamphetamine and pseudoephedrine in liquid-liquid extractions. A modified internal standard was used to calculate extraction efficiencies and recoveries were semi-quantitative. They varied between 50% - 90% for methamphetamine and 25% - 95% for pseudoephedrine, provided sufficient modifier was added. Derivatization by acetylation greatly improved the detection of pseudoephedrine. Recoveries of methamphetamine using targeted extraction procedures with hexane and 6.00 M sodium hydroxide or saturated sodium bicarbonate were adequate for qualitative confirmation. The extraction schemes with methylene chloride and chloroform proved best suited for low abundance and trace material analysis due to their increased recoveries.

- Description:
- A search for Higgs boson pair production pp -> hh is performed with 19.5 fb(-1) of proton-proton collision data at root s = 8TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products of each Higgs boson are reconstructed as a high-momentum b (b) over bar system with either a pair of small-radius jets or a single large-radius jet, the latter exploiting jet substructure techniques and associated b-tagged track-jets. No evidence for resonant or non-resonant Higgs boson pair production is observed. The data are interpreted in the context of the Randall-Sundrum model with a warped extra dimension as well as the two-Higgs-doublet model. An upper limit on the cross-section for pp -> G(KK)* -> hh -> b (b) over barb (b) over bar of 3.2 (2.3) fb is set for a Kaluza-Klein graviton G(KK)* mass of 1.0 (1.5) TeV, at the 95 % confidence level. The search for non-resonant Standard Model hh production sets an observed 95 % confidence level upper limit on the production cross-section sigma(pp -> hh -> b (b) over barb (b) over bar) of 202 fb, compared to a Standard Model prediction of s(pp -> hh -> b (b) over barb (b) over bar) = 3.6 +/- 0.5fb.

- Description:
- The purpose of the present thesis is to investigate an area of human experience which offers to each individual the opportunity to explore certain "unfinished" aspects of the self, to offer to his "finished" aspects information which will alter his already constructed configurations. This is the experience of human fantasy behavior. The writer believes that what is true for each man in the metaphorical description above may be true for science also. More particularly, the description is applicable to psychological science, for the experiences of fantasy are directly within the realm of psychology's domain. With respect to the study of fantasy behavior, psychology has had its blind spots; at times its blindness has been more than spotty. Up to the present time, fantasy behavior and its ramifications have tended not to be part of the study of the "common" man. Rather, scholastic and academic psychologies have limited their studies of human populations by taking "biased" samples. Such samples include the study of the fantasy processes of those who become emotionally unstable, persons who are in unusual need of outside aid before their fantasy processes can be explored with their awareness. Studies in clinical psychology often stress the practical application of techniques used to draw such material into the open. But the clinical researchers should not be criticized unjustly. Much of the content of the fantasy life of the usual, healthy, or normal individual is considered private unto himself. Most individuals may experience a screaming set of internal fantasy processes, yet remain quite serene outwardly. The experiences never pass into their awarenesses as being worthy of serious attention, let alone as information that should pass from their lips to others.

- Description:
- Many students lack social skills that hinder their success in school; students in special education are even more at risk. Social-emotional curricula have been developed to help build these social skills school-wide. Most research on the effects of social-emotional curricula has been conducted on general education students. The first purpose of this study was to measure the effects a social-emotional curriculum has on students with disabilities. Second Step was implemented on a weekly basis for 10 weeks in classrooms. The effectiveness of the Second Step program was evaluated by having special education students (N = 18) and teachers fill out a Skills Survey as a pre-test/post-test measure. Paired samples t-tests indicated insignificant gains according to teachers and students. Social Interactions Data observations served as an additional social skills measure. Non-overlapping data points indicated that the intervention did not increase social initiations (40%) and somewhat increased social responses (70%). The second purpose of this study was to examine the relationship between time in the least restrictive environment (LRE) and special education students’ social skills. There was a negative correlation between percentage of time included in general education and teacher reported growth and a positive correlation between inclusion percentage and student reported growth. The study suggests that research on social-emotional curricula, the effects curricula have on students in special education, and better measurement tools should continue to be conducted.
