Survivor reactions to organizational downsizing: The influence of justice perceptions and the psychological contract. (open access)

Survivor reactions to organizational downsizing: The influence of justice perceptions and the psychological contract.

The present study examined the relationships of organizational justice and the psychological contract with four outcome variables in a downsizing context. Multinational data were gathered from survivors representing a variety of organizations and industries. The main focus of the current study examined the relationships between survivors' perceptions of procedural, interpersonal, and informational justice and organizational commitment, job satisfaction, turnover intentions, and trust in management. Correlational data indicated that procedural, interpersonal, and informational justice all demonstrated significant correlations with the outcome variables with interpersonal justice demonstrating higher correlations with the outcome variables than procedural justice. Additionally, the results of two structural models indicated that, although both models fit the data equally well, interpersonal justice was the dominant predictor of the outcome variables. Finally, moderated multiple regression analyses indicated that the psychological contract did not act as a moderator on the relationships between the justice and the outcome variables. However, supplemental confirmatory factor analysis suggested that the justice variables might act as a mediator of the psychological contract - outcome variable relationships. Possible explanations of the results as well as implications for practice and future research are provided.

Synthesis and characterization of crystalline assembly of poly Nisopropylacry-lamide)-co-acrylic acid nanoparticles. (open access)

Synthesis and characterization of crystalline assembly of poly Nisopropylacry-lamide)-co-acrylic acid nanoparticles.

In this study, crystalline poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAm-co-AAc) nanoparticle network in organic solvents was obtained by self assembling precursor particles in acetone/epichlorohydrin mixture at room temperature followed by inter-sphere crosslinking at ~98 °C. The crystals thus formed can endure solvent exchanges or large distortions under a temporary compressing force with the reoccurrence of crystalline structures. In acetone, the crystals were stable, independent of temperature, while in water crystals could change their colors upon heating or changing pH values. By passing a focused white light beam through the crystals, different colors were displayed at different observation angles, indicating typical Bragg diffraction. Shear moduli of the gel nanoparticle crystals were measured in the linear stress-yield ranges for the same gel crystals in both acetone and water. Syntheses of particles of different sizes and the relationship between particle size and the color of the gel nanoparticle networks at a constant solid content were also presented. Temperature- and pH- sensitive crystalline PNIPAm-co-AAc hydrogel was prepared using osmosis crosslinking method. Not only the typical Bragg diffraction phenomenon was observed for the hydrogel but also apparent temperature- and pH- sensitive properties were performed. The phase behavior of PNIPAm nanoparticles dispersed in water was also investigated using a …

Synthesis and study of crystalline hydrogels, guided by a phase diagram. (open access)

Synthesis and study of crystalline hydrogels, guided by a phase diagram.

Monodispersed nanoparticles of poly-N-isopropylacrylamide-co-allylamine (PNIPAM-co-allylamine) and PNIPAM-co-acrylic acid (AA) have been synthesized and used as building blocks for creating three-dimensional networks. The close-packed PNIPAM-co-allylamine and PNIPAM-co-AA nanoparticles were stabilized by covalently bonding neighboring particles at room temperature and at neutral pH; factors which make these networks amicable for drug loading and release. Controlled release studies have been performed on the networks using dextran markers of various molecular weights as model macromolecular drugs. Drug release was quantified under various physical conditions including a range of temperature and molecular weight. These nanoparticle networks have several advantages over the conventional bulk gels for controlling the release of biomolecules with large molecular weights. Monodispersed nanoparticles of poly-N-isopropylacrylamide-co-allylamine (PNIPAM-co-allylamine) can self-assemble into crystals with a lattice spacing on the order of the wavelength of visible light. By initiating the crystallization process near the colloidal crystal melting temperature, while subsequently bonding the PNIPAM-co-allylamine particles below the glass transition temperature, a nanostructured hydrogel has been created. The crystalline hydrogels exhibit iridescent patterns that are tunable by the change of temperature, pH value or even protein concentration. This kind of soft and wet hydrogel with periodic structures may lead to new sensors, devices, and displays operating in aqueous …

Tantalum- and ruthenium-based diffusion barriers/adhesion promoters for copper/silicon dioxide and copper/low Îş integration. (open access)

Tantalum- and ruthenium-based diffusion barriers/adhesion promoters for copper/silicon dioxide and copper/low Îş integration.

The TaSiO6 films, ~8Å thick, were formed by sputter deposition of Ta onto ultrathin SiO2 substrates at 300 K, followed by annealing to 600 K in 2 torr O2. X-ray photoelectron spectroscopy (XPS) measurements of the films yielded a Si(2p) binding energy at 102.1 eV and Ta(4f7/2) binding energy at 26.2 eV, indicative of Ta silicate formation. O(1s) spectra indicate that the film is substantially hydroxylated. Annealing the film to > 900 K in UHV resulted in silicate decomposition to SiO2 and Ta2O5. The Ta silicate film is stable in air at 300K. XPS data show that sputter-deposited Cu (300 K) displays conformal growth on Ta silicate surface (TaSiO6) but 3-D growth on the annealed and decomposed silicate surface. Initial Cu/silicate interaction involves Cu charge donation to Ta surface sites, with Cu(I) formation and Ta reduction. The results are similar to those previously reported for air-exposed TaSiN, and indicate that Si-modified Ta barriers should maintain Cu wettability under oxidizing conditions for Cu interconnect applications. XPS has been used to study the reaction of tert-butylimino tris(diethylamino) tantalum (TBTDET) with atomic hydrogen on SiO2 and organosilicate glass (OSG) substrates. The results on both substrates indicate that at 300K, TBTDET partially dissociates, forming …

The Teaching of Children's Poetry: An Exploration of Instructional Practices in University Courses of Children's Literature, English, Language Arts, and Reading Education (open access)

The Teaching of Children's Poetry: An Exploration of Instructional Practices in University Courses of Children's Literature, English, Language Arts, and Reading Education

There are no studies which focus on the instructional practices employed in the teaching of children's poetry at the university level. This project aimed to describe the instructional practices utilized in the teaching of children's poetry at universities across the United States. Limited to the practices of the university professors and adjunct instructors who were members of the Children's Literature Assembly (CLA) of the National Council of Teachers of English (NCTE) at the time of this study, this investigation attempted to ascertain the general perceptions of poetry held by these university professors and adjunct instructors, their in-class instructional practices, and the types of poetry assignments given. Additionally, this study revealed both the poets typically highlighted and the goals held by professors and instructors in courses of children's literature, English, language arts, library science, and reading education. A mixed-methods design provided the framework for the descriptive data gleaned from the Poetry Use Survey. Quantitative data analysis yielded descriptive statistical data (means, standard deviations, ranges, percentages). Qualitative data analysis (manual and computer-assisted techniques) yielded categories and frequencies of response. Major findings included respondents': (a) belief that the teaching of poetry was important, (b) general disagreement for single, "correct" interpretations of poetry and …

Transplants

Access: Use of this item is restricted to the UNT Community
The body of work originating from this Problem in Lieu of Thesis consists of paintings on canvas that incorporate representations of plant material. The impetus for the paintings was black and white photocopies created from mounds of plant material placed on a copy machine. The resulting copies contained forms that were organic in appearance, but unrecognizable as known objects. Parts of the most interesting and ambiguous copies were used to develop the imagery of the paintings. The new forms served the purpose of creating visual interest from unexpected images. Combined with traditional painting techniques, the selected forms produced paintings of mysterious and playful worlds similar to those parts of the environment not readily accessed, such as galactic space, microscopic organisms, and ocean depths.

Treatment efficacy in a chronic pain population: Pre- to post-treatment.

Access: Use of this item is restricted to the UNT Community
The purpose of the current study was to investigate the effects of a multidisciplinary pain management program on five measures of subjective psychosocial factors. Ninety-five participants in the comprehensive multidisciplinary treatment group and the standard medical intervention control group were surveyed about various psychosocial factors using Axis II of the West Haven - Yale Multidimensional Pain Inventory (MPI), pre- to post-treatment. It was hypothesized that post-treatment levels would be significantly lower than pre-treatment levels for all five psychosocial variables. Additionally, gender and ethnicity variables were examined. Based on preliminary analyses indicating pre-treatment differences between the experimental and control group, five 2 x 2 x 3 analyses of covariances (ANCOVAs) were used to examine the above hypotheses. Results indicated significant differences between the treatment conditions on measures of control, with the comprehensive group feeling more in control than the standard group at post-treatment. No other significant main effects for treatment condition were found on the measures of pain severity, interference with daily activities, negative mood, or social support. However, a significant gender main effect was found for social support at post-treatment, with females reporting more social support than males. A significant gender x ethnicity interaction was also found for post-treatment control, …

Voting Operating System (VOS)

Access: Use of this item is restricted to the UNT Community
The electronic voting machine (EVM) plays a very important role in a country where government officials are elected into office. Throughout the world, a specific operating system that tends to the specific requirement of the EVM does not exist. Existing EVM technology depends upon the various operating systems currently available, thus ignoring the basic needs of the system. There is a compromise over the basic requirements in order to develop the systems on the basis on an already available operating system, thus having a lot of scope for error. It is necessary to know the specific details of the particular device for which the operating system is being developed. In this document, I evaluate existing EVMs and identify flaws and shortcomings. I propose a solution for a new operating system that meets the specific requirements of the EVM, calling it Voting Operating System (VOS, pronounced 'voice'). The identification technique can be simplified by using the fingerprint technology that determines the identity of a person based on two fingerprints. I also discuss the various parts of the operating system that have to be implemented that can tend to all the basic requirements of an EVM, including implementation of the memory manager, …

War and peace: Towards an understanding of the theology of jihad. (open access)

War and peace: Towards an understanding of the theology of jihad.

The growing number of terrorist attacks waged by Islamic fundamentalists has led to an increasing desire to understand the nature of jihad. These attacks have led to a renewed sense of urgency to find answers to such questions as why these attacks occur, and who they are waged against. Towards this end I turn to examine the political philosophy of four Muslim theologians. Specifically I look at the political philosophy of Sayyid Qutb, Shah Walai Allah Dihlawai, Ibn Rushd (Averroes), and Muhammad Sa'id al-Ashmawy. I find that the notion of jihad is very inconclusive. Furthermore, the question of jihad revolves largely around the question of whether or not individuals can be reasoned with, and secondly whether religion should be compelled upon individuals.
