While spoken codeswitching (CS) among Latinos has received significant scholarly attention, few studies have examined written CS, specifically naturally-occurring CS in email. This study contributes to an under-studied area of Latino linguistic practices by reporting the results of a study of CS in the emails of five Spanish-English bilingual Latinos. Methods are employed that are not often used in discourse analysis of email texts, namely multi-dimensional scaling and tree diagrams, to explore the contextual parameters of written Spanish-English CS systematically. Consistent with the findings of other studies of CS in CMC, English use was most associated with professional or formal contacts, and use of Spanish, the participants’ native language, was linked to intimacy, informality, and group identification. Switches to Spanish functioned to personalize otherwise transactional or work-related English-dominant emails. The article also discusses novel orthographic and linguistic forms specific to the CMC context.

This paper reports on the results of a research project, on comparing one virtual collaborative environment with a first-person visual immersion (first-perspective interaction) and a second one where the user interacts through a sound-kinetic virtual representation of himself (avatar), as a stress-coping environment in real-life situations. Recent developments in coping research are proposing a shift from a trait-oriented approach of coping to a more situation-specific treatment. We defined as real-life situation a target-oriented situation that demands a complex coping skills inventory of high self-efficacy and internal or external "locus of control" strategies. The participants were 90 normal adults with healthy or impaired coping skills, 25-40 years of age, randomly spread across two groups. There was the same number of participants across groups and gender balance within groups. All two groups went through two phases. In Phase I, Solo, one participant was assessed using a three-stage assessment inspired by the transactional stress theory of Lazarus and the stress inoculation theory of Meichenbaum. In Phase I, each participant was given a coping skills measurement within the time course of various hypothetical stressful encounters performed in two different conditions and a control group. In Condition A, the participant was given a virtual stress assessment scenario relative to a first-person perspective (VRFP). In Condition B, the participant was given a virtual stress assessment scenario relative to a behaviorally realistic motion controlled avatar with sonic feedback (VRSA). In Condition C, the No Treatment Condition (NTC), the participant received just an interview. In Phase II, all three groups were mixed and exercised the same tasks but with two participants in pairs. The results showed that the VRSA group performed notably better in terms of cognitive appraisals, emotions and attributions than the other two groups in Phase I (VRSA, 92%; VRFP, 85%; NTC, 34%). In Phase II, the difference again favored the VRSA group against the other two. These results indicate that a virtual collaborative environment seems to be a consistent coping environment, tapping two classes of stress: (a) aversive or ambiguous situations, and (b) loss or failure situations in relation to the stress inoculation theory. In terms of coping behaviors, a distinction is made between self-directed and environment-directed strategies. A great advantage of the virtual collaborative environment with the behaviorally enhanced sound-kinetic avatar is the consideration of team coping intentions in different stages. Even if the aim is to tap transactional processes in real-life situations, it might be better to conduct research using a sound-kinetic avatar based collaborative environment than a virtual first-person perspective scenario alone. The VE consisted of two dual-processor PC systems, a video splitter, a digital camera and two stereoscopic CRT displays. The system was programmed in C++ and VRScape Immersive Cluster from VRCO, which created an artificial environment that encodes the user's motion from a video camera, targeted at the face of the users and physiological sensors attached to the body.

Pay for performance can have a positive or a negative influence on actual performance. The aim of this study was to give an explanation for this contradiction.We demonstrated that the variability of the payment can act as a stressor. According to the transactional model of stress, the influence on performance depends on the subjective interpretation of the variability as challenge or threat. Therefore we manipulated the degree of variability. The data showed decreasing performance for participants who preferred less-variable payments. They performed better under a less-variable rather than more-variable payment. The participants who preferred more-variable payment schemes showed the opposite pattern. These participants showed a higher performance under a more-variable rather than less-variable payment scheme.

An indicated preventive intervention research program integrating attachment, attributional, and behaviorist perspectives was conducted to test the hypothesis that parent-child relationship disturbances directly effect the child's adjustment to the preschool. Anxious-withdrawn preschool children and their mothers were divided equally into treatment and control groups, and assessed on maternal self-report of parenting stress, behavioral ratings of mother-child interaction, and teacher ratings of the children in the preschool classroom. Results showed significant changes in the treatment group: mothers in the treatment group moderated their level of control to a more appropriate, less intrusive level, while children in the treatment group showed an increase in cooperation and enthusiasm during a problem solving task with mother. Teacher-rated social competence and anxious-withdrawn behavior indicated improvement, although only the former was significant. The demonstration of effects of this home intervention for the mother on the child's behavior in the preschool confirm the transactional model underlying this study and demonstrate the utility of a parent-child interaction training component for the prevention of behavioral-emotional problems in young children.

There is growing interest in providing women with internatal care, a package of healthcare and ancillary services that can improve their health during the period after the termination of one pregnancy but before the conception of the next pregnancy. Women who have had a pregnancy affected by a neural tube defect can especially benefit from internatal care because they are at increased risk for recurrence and improvements to their health during the inter-pregnancy period can prevent future negative birth outcomes. The dissertation provides three papers that inform the content of internatal care for women at risk for recurrence by examining descriptive epidemiology to develop an accurate risk profile of the population, assessing whether women at risk for recurrence would benefit from a psychosocial intervention, and determining how to improve health promotion efforts targeting folic acid use.^ Paper one identifies information relevant for developing risk profiles and conducting risk assessments. A number of investigations have found that the risk for neural tube defects differs between non-Hispanic Whites and Hispanics. To understand the risk difference, the descriptive epidemiology of spina bifida and anencephaly was examined for Hispanics and non-Hispanic Whites based on data from the Texas Birth Defects Registry for the years 1999 through 2004. Crude and adjusted birth prevalence ratios and corresponding 95% confidence intervals were calculated between descriptive epidemiologic characteristics and anencephaly and spina bifida for non-Hispanic Whites and for Hispanics. In both race/ethnic groups, anencephaly expressed an inverse relationship with maternal age and a positive linear relationship with parity. Both relationships were stronger in non-Hispanic Whites. Female infants had a higher risk for anencephaly in non-Hispanic Whites. Lower maternal education was associated with increased risk for spina bifida in Hispanics.^ Paper two assesses the need for a psychosocial intervention. For mothers who have children with spina bifida, the transition to motherhood can be stressful. This qualitative study explored the process of becoming a mother to a child with spina bifida focusing particularly on stress and coping in the immediate postnatal environment. Semi-structured interviews were conducted with six mothers who have children with spina bifida. Mothers were asked about their initial emotional and problem-based coping efforts, the quality and kind of support provided by health providers, and the characteristics of their meaning-based coping efforts; questions matched Transactional Model of Stress and Coping (TMSC) constructs. Analysis of the responses revealed a number of modifiable stress and coping transactions, the most salient being: health providers are in a position to address beliefs about self-causality and prevent mothers from experiencing the repercussions that stem from maintaining these beliefs. ^ Paper three identifies considerations when creating health promotion materials targeting folic acid use. A brochure was designed using concepts from the Precaution Adoption Process Model (PAPM). Three focus groups comprising 26 mothers of children with spina bifida evaluated the brochure. One focus group was conducted in Spanish-only, the other two focus groups were conducted in English and Spanish combined. Qualitative analysis of coded transcripts revealed that a brochure is a helpful adjunct. Questions about folic acid support the inclusion of an insert with basic information. There may be a need to develop different educational material for Hispanics so the importance of folic acid is provided in a situational context. Some participants blamed themselves for their pregnancy outcome which may affect their receptivity to messages in the brochure. The women's desire for photographs that affect their perception of threat and their identification with the second role model indicate they belong to PAPM Stage 2 and 3. Participants preferred colorful envelopes, high quality paper, intimidating photographs, simple words, conversational style sentences, and positive messages.^ These papers develop the content of risk assessment, psychosocial intervention, and health promotion components of internatal care as they apply to women at risk for recurrence. The findings provided evidence for considering parity and maternal age when assessing nutritional risk. The two dissimilarities between the two race/ethnic groups, infant sex and maternal education lent support to creating separate risk profiles. Interviews with mothers of children with spina bifida revealed the existence of unmet needs-suggesting that a psychosocial intervention provided as part of internatal care can strengthen and support women's well-being. Segmenting the audience according to race/ethnicity and PAPM stage can improve the relevance of print materials promoting folic acid use.^

HIV incidence has not changed since the introduction of the pandemic. Daily 14,000 persons are infected with HIV and 25 to 50% of the HIV-infected population and subgroups respectively are estimated to be unaware of their HIV diagnosis. Perinatally-infected HIV-positive youth, aged 13-24 years, have survived unexpectedly into adulthood, have had unique HIV disclosure experiences and now face HIV disclosure issues of adulthood and perhaps parenthood. Despite new effective HIV therapies, no HIV prevention plan exists that has diminished the rate of new HIV infections. HIV stigma and lack of universal HIV reporting laws dissuade timely HIV disclosure. Missed HIV disclosure perpetuates HIV transmission and infection. Understanding the attitudes and beliefs of HIV disclosure among perinatally-infected HIV-positive youth and their caregivers may uncover reasons to HIV disclosure delays, avoidance and intentions. The Care to Share HIV Disclosure study was designed to identify the attitudes and beliefs of HIV disclosure among HIV-positve youth (aged 13-24 years), who were infected from birth and who knew their HIV diagnosis, along with their caregivers. Twenty-six participants (15 youth and 11 caregivers) completed the theory-based questionnaires of a 21-item multiple choice survey on HIV disclosure framed in the Theory of Reasoned Action and Theory of Planned Behavior and included an additional open-ended survey that applied the Transactional Model of Stress and Coping to address youth's and caregivers' HIV disclosure experiences. Youth were found to have a selective unfavorable HIV disclosure outcome when among referents of close friends. However youth did believe in HIV partner notification. For caregivers, it mattered who disclosed the HIV illness to the youth. HIV stigma was of concern based on the youths' tendency to believe in keeping HIV a secret and their caregivers' ambivalence to HIV secrecy. However, favorable HIV disclosure outcomes were identified for both youth and caregivers the potential for HIV disclosure: when seeking HIV knowledge, when around caregivers and close family and in situations of perceived controllability as when helping others learn about HIV. These findings unveil HIV disclosure attitudes and beliefs within this population and may reveal the attributes that may inhibit or promote HIV disclosure behaviors. HIV disclosure studies that address attitudes and beliefs among larger populations of youth and HIV-infected persons are necessary to identify effective individual, group and society approaches that would promote timely, responsible and meaningful HIV disclosure methods that promote a healthy identity and interrupt HIV transmission.^

Introduction. Patient safety culture is the integration of interrelated practices that once developed is supported by both the culture and leadership of the organization (Sagan, 1993). The purpose of this study is to describe and examine the relationship between surgical residents’ perception of their leadership and the resulting organizational safety culture within their clinical setting. This assessment is important to understanding the extent that leadership style affects the perception of the safety culture.^ Methods. A secondary dataset was used which included data from 68 surgical residents from two survey instruments, Organizational Description Questionnaire (ODQ) and Patient Safety Climate In Healthcare Organizations (PSCHO) Survey. Multiple regressions followed by hierarchical regressions with the introduction of the Post Graduate Year (PGY) variable examined the association between the leadership styles, Transactional and Transformational and the organizational safety culture variables, Overall Emphasis on Safety, Senior management engagement, Organizational resources for safety. Independent t-tests were conducted to assess whether males and females differ among the organizational safety culture variables and either leadership style.^ Results. The surgical residents perceived their organizational leadership to have greater emphasis placed on transformational leadership culture style relative to transactional leadership culture style. The only significant association found was between Transformational leadership and Organizational resources for safety. PGY had no significant effect on the leadership or the safety culture perceived. No significant difference was found between females and males in regards to the safety culture or the leadership style.^ Discussion. These results have implications as they support the premise for the study which is surgical residents perceive their existing leadership and organizational culture to be more transformational in nature than transactional. Significance was found between the leadership perceived and one of the safety culture variables, Organizational resources for safety. The foundation for this association lies in the fact that surgical residents are the personnel which are a part of the organizational resources. Although PGY differentiation did not seem to play a difference in the leadership perceived this could be attributed to the small sample size. No gender difference were found which supports the assumption that within such a highly specialized group such as surgical residents there is no gender differences since the highly specialized field draws a certain type of person with distinct characteristics. In future research these survey tools can be used to gauge the survey audiences’ perception and safety interventions can be developed based on the results. ^

This dissertation focuses on the leadership styles of managers, the impact these leadership styles have on the job satisfaction of staff nurses, and the proclivity of nurses to consider unionization. The aims of the dissertation include conducting a literature review on topics of leadership style, job satisfaction, and unionization; identifying and elucidating pertinent constructs with respect to shared interrelationships and how they could be measured; and developing a means of assessing if and to what extent transformational and transactional leadership styles affect nurse proclivity to unionize.^ The instrumentation selected includes the Multifactor Leadership Survey, Job Satisfaction Survey, and a newly created Union Preference Survey. Each survey instrument was evaluated as to its appropriateness to administer at a non-consultant level within a health care facility. Options other than self-administering the survey instruments include online access for participants, which provides confidentiality and encourages more responses. ^ The next part of the dissertation is a plan for health care facilities to use the survey tool by administering it themselves. The plan provides a general description of the survey tool, administering the instrument, rating the instrument, and leadership development. Integration of the three surveys is presented in a non-statistical format by coordinating the results of the three survey instrument responses. Recommendations are presented on how to improve leadership development warranted for improvement.^ The conclusions reached are that nurses’ preference for unions is influenced by the leadership style of direct report managers, as rated by staff nurses, and the nurses’ job satisfaction, which is in turn in part dependent on their managers’ leadership style. Thus, changes in leadership style can have a profound impact on nurse job satisfaction and on nurses’ preference for unionization.^

Los textos académicos a los que los alumnos acuden en busca de información no siempre les resultan fácilmente comprensibles. Se observa que en el nivel pragmático las dificultades son muy importantes y revelan interferencias en la construcción de sentido del texto, a veces por limitaciones de la competencia de los lectores y otras veces por problemas en la organización retórica de los textos. Este trabajo se propone abordar y analizar la incidencia de los conocimientos sobre la distribución de la información de los textos, en las posibilidades de los alumnos para alcanzar la comprensión de los mismos. Se seguirá la concepción de Rosenblatt sobre la lectura como proceso transaccional entre el lector que construye el sentido sobre la base de las pistas literales o inferenciales que el texto le ofrece, y de Kintsch y van Dijk sobre la comprensión como un proceso cognitivo que se desarrolla en tres etapas: decodificación, recuperación del texto base y construcción del modelo de situación. El análisis de la incidencia de los conocimientos previos de los lectores para 'dosificar' la nueva información, se apoyará en las funciones informativas del texto desarrolladas por la Escuela de Praga (especialmente tópico, tema y rema) para analizar de qué manera estas funciones pueden sustentar estrategias de lectura que activen en los lectores los procesos cognitivos correspondientes a la fase más elaborada de la comprensión, denominada construcción del modelo de situación. Para ello se analizarán las respuestas obtenidas frente a dos textos informativos sobre el mismo tema, de distinta complejidad, antes y después de capacitar a los alumnos en conocimientos específicos. Los resultados obtenidos permiten concluir que tales conocimientos favorecen el desempeño de los alumnos, particularmente en el caso de textos en los que la distribución de la información es más compleja

Sheepskin market in Ethiopia seems to enjoy the benefits of the economic liberalization policy since 1991, such as price deregulation or liberalization of economic activities. The close observation on the profiles and activities of each actor in the marketing channel, however, illustrates that the actors have tried to complement the lack of appropriate infrastructure and legal protection, which should be provided by the government, through utilizing their social and blood ties. While these ties have implemented the role of the government, there are risks that the marketing channel might be developed based on coalition with social network and the poor without the network would be excluded.

Production and consumption of broiler meat has expanded rapidly in Peru since the 1990s. This rapid expansion was possible due to technological changes in production as well as integration of various stages of production, such as breeding farms, hatcheries, feed mills and grow-out farms by so-called broiler integrators. However, there are some distinguishing characteristics in Peruvian broiler integration that differ from those in developed countries. One is the truncated scope of integration, in which the slaughtering and processing stages are not integrated. The other is that not slaughtering and processing companies, but grow-out farms have become the principal broiler integrators. This paper analyzes the factors associated with these characteristics.

During the transition period from a planned economy to a market economy in 1990s of China, there was a considerable accrual of deferred payment, and default due to inferior enforcement institutions. This is a very common phenomenon in the transition economies at that time. Interviews with home electronics appliance firms revealed that firms coped with this problem by adjusting their sales mechanisms (found four types), and the benefit of institutions was limited. A theoretical analysis claim that spot and integration are inferior to contracts, a contract with a rebate on volume and prepayment against an exclusive agent can realize the lowest cost and price. The empirical part showed that mechanisms converged into a mechanism with the rebate on volume an against exclusive agent and its price level is the lowest. The competition is the driving force of the convergence of mechanisms and improvement risk management capacity.

One of the main challenges facing next generation Cloud platform services is the need to simultaneously achieve ease of programming, consistency, and high scalability. Big Data applications have so far focused on batch processing. The next step for Big Data is to move to the online world. This shift will raise the requirements for transactional guarantees. CumuloNimbo is a new EC-funded project led by Universidad Politécnica de Madrid (UPM) that addresses these issues via a highly scalable multi-tier transactional platform as a service (PaaS) that bridges the gap between OLTP and Big Data applications.
