Non-Academic Institutional Variables Related to Degree Completion of Non-Traditional Age Undergraduate Students (open access)

Non-Academic Institutional Variables Related to Degree Completion of Non-Traditional Age Undergraduate Students

A study was conducted at The University of Texas at Arlington to obtain measurements of non-traditional age undergraduate students using the Mattering Scales for Adult Students in Higher Education (MHE). The MHE is designed to assess the perceptions of adult students on how much they matter to the institution they are attending. The study also sought to determine if "mattering" and other selected nonacademic variables associated with the university environment are perceived by nontraditional age students to effect their likelihood of completing their baccalaureate degree. Of the five subscales surveyed by the MHE, significant statistical differences were found to exist in the Administration, Interaction With Peers, Multiple Roles, and Faculty subscales denoting an interaction between gender and minority status. Significant statistical differences were also found by gender on the Advising subscale and by minority status on the Faculty subscale.

Trust and Governance in Hybrid Relationships: An Investigation of Logistics Alliances (open access)

Trust and Governance in Hybrid Relationships: An Investigation of Logistics Alliances

Transaction cost economics (TCE) theorists traditionally have classified transactions between firms as governed by either market or hierarchy. By assessing characteristics of the transaction - asset specificity, uncertainty, and frequency - firms choose the governance form which minimizes transaction costs, the costs of administering the business deal. During the 1980s, however, TCE has found itself unable to explain the proliferation of strategic alliances. These hybrid relationships seek the benefits of both markets and hierarchies, including quasi-integration, the control of assets without actual ownership. Further, hybrids tend to prefer trust-based relational contracting. TCE's acknowledgment of hybrids, however, raises other questions surrounding the behavioral assumptions which supposedly influence the transaction characteristic governance linkage. Various dissenting researchers have theorized that (1) trust is more dominant in business than opportunism (2) the behavioral assumptions actually function as variables in different contexts, and (3) trust offers an integration mechanism for behavioral variables.

Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends (open access)

Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends

Thermoplastic polyimides (TPIs) exhibit high glass transition temperatures (Tgs), which make them useful in high performance applications. Amorphous and semicrystalline TPIs show sub-Tg relaxations, which can aid in improving strength characteristics through energy absorption. The a relaxation of both types of TPIs indicates a cooperative nature. The semicrystalline TPI shows thermo-irreversible cold crystallization phenomenon. The polymer liquid crystal (PLC) used in the blends is thermotropic and with longitudinal molecular structure. The small heat capacity change (ACP) associated with the glass transition indicates the PLC to be rigid rod in nature. The PLC shows a small endotherm associated with the melting. The addition of PLC to the semicrystalline TPI does not significantly affect the Tg or the melting point (Tm). The cold crystallization temperature (Tc) increases with the addition of the PLC, indicating channeling phenomenon. The addition of PLC also causes a negative deviation of the ACP, which is another evidence for channeling. The TPI, PLC and their blends show high thermal stability. The semicrystalline TPI absorbs moisture; this effect decreases with the addition of the PLC. The absorbed moisture does not show any effect on the degradation. The addition of PLC beyond 30 wt.% does not result in an improvement …

Experimental and Theoretical Studies of Polycarbocyclic Compounds

Part I. Diels-Alder cycloadditions of 1,2,3,4,9,9-hexachloro-1α,4α,4aα,8aβ-tetrahydro-l,4-methanonaphthalene (32) and 1,2,3,4,9,9-hexachloro-lα,4α,6,7- tetrahydro-l,4-methanonaphthalene (33) to 4-methyl- and 4-phenyl-l,2,4-triazoline-3,5-dione [MTAD and PTAD, respectively] and to N-methylmaleimide (NMM) have been studied. The structures of several of the resulting cycloadducts were determined by X-ray crystallographic methods. The observed stereoselectivity of each of these Diels-Alder reactions was further investigated via application of theoretical methods. Thus, semiempirical (AMI) and ab initio molecular orbital calculations were used to calculate relative energies. Ab initio calculations were employed to perform frontier molecular orbital analyses of diene-dienophile interactions.

The Relationship between Parental Empathy and Parental Acceptance and the Effect of Filial Therapy Training on this Relationship (open access)

The Relationship between Parental Empathy and Parental Acceptance and the Effect of Filial Therapy Training on this Relationship

This study was conducted to determine the relationship between parental empathy (PE) and parental acceptance (PA) and the effect of filial therapy training (FTT) on this relationship. Filial therapy training is a parent education program in which the goal is the development of PE and PA. The Measurement of Empathy in Adult-Child Interaction (MEACI) and the Porter Parental Acceptance Scale (PPAS) are two widely used instruments in filial therapy studies to measure PE and PA, respectively. The purpose of this study was to determine the relationship between parental empathy and parental acceptance, and the effect of filial therapy training on this relationship. Specifically, this study was designed to investigate the correlations between the MEACI and the PPAS.

Quantum-Confined CdS Nanoparticles on DNA Templates (open access)

Quantum-Confined CdS Nanoparticles on DNA Templates

As electronic devices became smaller, interest in quantum-confined semiconductor nanostructures increased. Self-assembled mesoscale semiconductor structures of II-VI nanocrystals are an especially exciting subject because of their controllable band gap and unique photophysical properties. Several preparative methods to synthesize and control the sizes of the individual nanocrystallites and the electronic and optical properties have been intensively studied. Fabrication of patterned nanostructures composed of quantum-confined nanoparticles is the next step toward practical applications. We have developed an innovative method to fabricate diverse nanostructures which relies on the size and a shape of a chosen deoxyribonucleic acid (DNA) template.

Masculine Role Conflict in Gay Men: Mediation of Psychological Well-Being and Help-Seeking Behaviors (open access)

Masculine Role Conflict in Gay Men: Mediation of Psychological Well-Being and Help-Seeking Behaviors

Gender role issues have been an integral part of psychology since the 1970s. More recently, theories and research have surfaced concerning the issues of maleness in our society. Most of these theories focus on masculine gender role and how it affects men in various ways, e.g., their psychological well-being, substance use, relational abilities, and help-seeking behaviors. One area of maleness that has consistently been left out of the Masculine Role Conflict (MRC) debate is that of homosexuality. As a gay man develops, he finds himself at odds with society over something that he experiences biologically as normal and appropriate. It is the contention of this paper that MRC is an issue related to psychological distress among gay men and not psychological weakness in gay men, per se.

Culture and Anxiety: a Cross-Cultural Study (open access)

Culture and Anxiety: a Cross-Cultural Study

By measuring interactions among and between anxiety and the independent variables of country of origin, gender, level of education, and age, this study attempted to gain insight into how students from different countries experience anxiety on a U.S. college campus. Results of the Multivariate Analysis of Variance (MANOVA) and the univariate test(ANOVA) indicated that the gender and level of education of the subjects made no significant difference. However, when it came to country of origin, there were significant differences between two of the cultural groups and respective anxiety level. Findings also support a positive correlation between age and anxiety levels, with the youngest participants having the lowest anxiety levels.

Studies in Bank Contagion: Three Regulatory Events (open access)

Studies in Bank Contagion: Three Regulatory Events

This research describes an analysis, using event-study methodology, of the reaction of the stock returns of a sample, drawn from the one-hundred largest bank holding companies, to certain actions of regulatory agencies. The first part of the analysis examines the reaction of the bank stocks to the closure of the Bank of New England, using cross-sectional variables not previously examined by other investigators. The second event considers the invalidation of interest-rate swap contracts by the British Law Lords, the highest court in Britain. The third case is an examination of the effects of actions taken to enforce the Community Reinvestment Act. All three events have significant abnormal returns in at least one sub-sample and event window. The results of the cross-sectional analysis and the lack of response to later events are consistent with market efficiency in the semi-strong form. The results are also consistent with the hypothesis that regulatory policies that emphasize consistency and banking system safety are desirable.

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis (open access)

Convergence of Self and Other Ratings of Personality: a Structural Equation Analysis

Recently, multi-source feedback has been a popular way of providing performance-related feedback to individuals in many organizations. Many who use multi-source feedback consider Rating Convergence, others seeing target individuals as they see themselves, to be a positive outcome of this process. However, the variables that account for Rating Convergence are not known. This study investigated whether the personality factor Extroversion and Behavioral Consistency, acting as a moderator variable, could account for Self-other Rating Convergence, particularly the Convergence between self and peer Ratings. The sample consisted of 235 mid-level managers from a variety of industries who were participants in individual career development workshops. Using structural equation modeling, the results indicated that a model consisting of a single Extroversion factor could account for the convergence of self-peer ratings. This finding calls into question the significance of Rating Convergence when using multi-source rating instruments that provide feedback on trait characteristics since it may be heavily influenced by a single personality factor rather than observers' comprehensive understanding of the ratee's performance.

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems (open access)

Natural Smooth Measures on the Leaves of the Unstable Manifold of Open Billiard Dynamical Systems

In this paper, we prove, for a certain class of open billiard dynamical systems, the existence of a family of smooth probability measures on the leaves of the dynamical system's unstable manifold. These measures describe the conditional asymptotic behavior of forward trajectories of the system. Furthermore, properties of these families are proven which are germane to the PYC programme for these systems. Strong sufficient conditions for the uniqueness of such families are given which depend upon geometric properties of the system's phase space. In particular, these results hold for a fairly nonrestrictive class of triangular configurations of scatterers.

Structural and Photoelectron Emission Properties of Chemical Vapor Deposition Grown Diamond Films (open access)

Structural and Photoelectron Emission Properties of Chemical Vapor Deposition Grown Diamond Films

The effects of methane (CH4), diborone (B2H6) and nitrogen (N2) concentrations on the structure and photoelectron emission properties of chemical vapor deposition (CVD) polycrystalline diamond films were studied. The diamond films were grown on single-crystal Si substrates using the hot-tungsten filament CVD technique. Raman spectroscopy and x-ray photoelectron spectroscopy (XPS) were used to characterize the different forms of carbon in the films, and the fraction of sp3 carbon to sp3 plus sp2 carbon at the surface of the films, respectively. Scanning electron microscopy (SEM) was used to characterize the surface morphology of the films. The photoelectron emission properties were determined by measuring the energy distributions of photoemitted electrons using ultraviolet photoelectron spectroscopy (UPS), and by measuring the photoelectric current as a function of incident photon energy.

The Relationship between Privatization, Culture, Adoption of International Accounting Standards, and Accounting in Egypt (open access)

The Relationship between Privatization, Culture, Adoption of International Accounting Standards, and Accounting in Egypt

This study explores how the Egyptian socioeconomic factors impacted the implementation of International Accounting Standards (IASs) in Egypt. Prior research concluded that developing nations have special needs when it comes to accounting and financial reporting and recommended nation-specific analysis. The author adapts Gray's (1988) model, which connects Hofstede's cultural dimensions with accounting practice, to fit the Egyptian environment.

Peer Mediation: an Empirical Exploration Empowering Elementary School Children to Resolve Conflicts Constructively (open access)

Peer Mediation: an Empirical Exploration Empowering Elementary School Children to Resolve Conflicts Constructively

Conflict is inevitable in school and in life. Many children lack skills necessary to resolve daily conflicts constructively. Without knowledge of positive ways to manage conflicts, violence may result. Limited research suggests that involvement in a peer mediation program may have a positive influence on children. This study assessed effects peer mediation training and mediation experience had on student mediators. The pretest-posttest, control-group, and quasi-experimental study investigated the effects of a year long peer mediation program implemented in a suburban elementary school.

Circumfusion: a Composition for Real-Time Computer Music Spatialization System (open access)

Circumfusion: a Composition for Real-Time Computer Music Spatialization System

Two of the leading methodologies for spatializing audio over multiple channels include non-real-time multi-track tape and variations of real-time systems that often involve complex configurations of hardware. Of the latter, composers relying on MIDI as a control source have used pairs of sound modules, effects units and automation capable mixers to achieve spatialization over four loudspeakers. These systems typically employ intensity panning, Doppler shifts and reverberation. The present research details the development of a compact spatialization system using a MAX patch controlling a Kurzweil K2500 sampler. This system supports real-time diffusion of up to six simultaneous sound files over eight loudspeakers while incorporating intensity panning, Doppler shifts, delays and filtering. The MAX patch allows composers to choose from several automatic sound spatialization trajectories or to use the mouse to draw and store their own trajectories for later playback. The piece, Circumfusion, is an eighteen-minute composition of electroacoustic music utilizing this spatialization system.
