Predictors of Affective Organizational Commitment Among High School Principals

(ABSTRACT) This study was an assessment of the importance of age, gender, organizational tenure, perceived organizational support, perceived fairness, and perceived autonomy in explaining affective organizational commitment among high school principals in the United States. Stepwise multiple regression was used to determine which independent variables explained a portion of the dependent variable, affective organizational commitment. A sample of 396 high school principals, stratified by gender, was drawn from a national data base developed by Quality Education Data of Denver, CO. The sample consisted of 132 females and 264 males. Data were collected from responses to a questionnaire that was mailed to all persons in the sample. Usable responses were received from 60 females and from 142 males. Results of the stepwise multiple regression indicated that 58 percent of the variation in affective organizational commitment among high school principals was explained by perceived fairness, organizational tenure, perceived organizational support, and high school principals' age. Perceived fairness explained the greatest percentage of variation; age, which entered the regression equation last, explained the least amount of variation. This study indicates that high school principals, first and foremost, valued fairness from school districts in return for their commitment to school districts. The challenge for superintendents and others who work with high school principals is to maintain fairness in educational settings where there are many diverse and competing student needs in the same school district. iii DEDICATION This dissertation is dedicated with gratitude and affection to my wife, Lillie, and to my daughter, Tamika. iv ACKNOWLEDGMENTS The researcher expresses sincere appreciation to Dr. the researcher in the early stages of this study.

Control and stabilization of an underactuated surface vessel

This paper studies the problem of controlling the planar position and orientation of an autonomous surface vessel using two independent thrusters. It is first shown that although the system is not asymptotically stabilizable to a given equilibrium configuration using a time-invariant continuous feedback, it is strongly accessible and small-time locally controllable at any equilibrium. Time-invariant discontinuous feedback control laws are then constructed to asymptotically stabilize the system to the desired configuration with exponential convergence rates. A simulation example is included to demonstrate the results.

UserProfile-based personalized research paper recommendation system

This paper proposed UserProfile-based PRPRS (Personalized Research Paper Recommendation System) and an algorithm for extracting keyword is designed and implemented by keyword extraction and keyword inference. Whenever collected research papers by topic are selected, a renewal of user profile increases the frequency of each Domain, Topic and keyword. Each ratio of occurrence is recalculated and reflected on UserProfile. PRPRS calculates the similarity between given topic and collected papers by using Cosine Similarity which is used to recommend initial paper for each topic in Information retrieval. We measured satisfaction and accuracy for each system-recommended paper to test and evaluated performances of the suggested system. Finally PRPRS represents high level of satisfaction and accuracy.
The Examination of Changes in Dynamic Risk Factors and Recidivism Over Time in Youth Offenders

Risk assessments that include dynamic risk factors are increasingly being utilized within the youth justice system to predict a young person’s likelihood to reoffend, to assist with case management, and to better inform intervention services. Based on the principles of the Risk-Need-Responsivity (RNR) framework, the Youth Level of Service/Case Management Inventory (YLS/CMI) is a widely used risk assessment tool that demonstrates strong psychometric properties among youth offenders. However, most studies to date have relied solely on single-wave, cross-sectional research designs that essentially treat dynamic risk factors as static. The purpose of the present study was to determine whether the RNR dynamic risk factors assessed by the YLS/CMI do in fact change over time and whether identifying these changes improved the prediction of recidivism. To answer these research questions, 20
Organisational resistance strategies to unwanted accounting and finance changes: the case of general medical practice in the UK

This paper explores the resistance strategies of organisations to unwanted changes. It is concerned with the way satellite organisations are created to provide a counter force to environmental disturbances such as changes introduced in the context of what has come to be called New Public Management. Its particular focus is with the attempt to develop and institutionalize external, “public” forms of resistance rather than undertake more internal, “private” forms. The specific empirical focus is general medical practice in the UK, where commissioning groups were formed as an alternative to GP fundholding. To help analyse this empirical detail we draw insights from Habermas’s model of society, organisational change theory and institutional theory. In the process the paper not only amplifies the empirical reactions of GP practices in the UK but also uses this empirical detail to develop the nature of this theoretical base by adding new dimensions concerning organisational resistance.
Labour market uncertainty and migration policy Canadian, German and Spanish experiences compared

The recent economic crisis has highlighted the issue of unequal distribution of vulnerability among categories of employees, which is exacerbated in times of perceived uncertainty. One major line of labour market segmentation in terms of security is between national citizens and immigrants, as illustrated by the seminal work of Piore (1979): immigrants may then carry an over-proportional burden of uncertainty and act as a ‘buffer’ in cases of employment level shocks, alongside other peripheral employment groups such as women, youth and aged workers. Immigrant workers may be subjectively more prone than those other peripheral groups (especially women) to accept high levels of flexibility, mobility and overall uncertainty. Moreover, such an arrangement has the political advantage, for national policy makers, of shifting the burden of uncertainty on to non citizens, who cannot punish the government through their democratic vote and therefore their unemployment or forced mobility may be less costly. Alternatively, immigrants might even abandon the country in case of downturns, whether freely or forcedly. Within a context of increased labour market uncertainty, the distribution of it between different groups is of increased political and social relevance (Crouch 2011). However, an intentional use of migrants as secondary segment of the workforce implies a high degree of integration between migration policy and labour market policy, or the demographic consequences of unplanned immigration may be even more costly, politically, than labour market uncertainty as such.
Analysis of the early response to TSST‐1 reveals Vβ‐unrestricted extravasation, compartmentalization of the response, and unresponsiveness but not anergy to TSST‐1

Staphylococcal toxic shock syndrome toxin 1 (TSST‐1) is the major cause of toxic shock syndrome and is important in the pathophysiology of staphylococcal septic shock. Our study about the biological effects of TSST‐1 in the rabbit 3 and 6 h and 7 days postinjection provides evidence that TSST‐1 induces leukopenia, lymphopenia, and monocytopenia as a result of extravasation of cells in a Vß‐unrestricted manner. Cells in the circulation, reduced significantly in numbers, show the same phenotypic distribution as before TSST‐1 injection. Three hours post‐in vivo TSST‐1 injection, we demonstrated compartmentalization of the response. By quantitative RT‐PCR, the induction of mRNA expression of TH1 and inflammatory cytokines in the spleen and lung and a complete lack of induction in PBMC could be shown. Proliferation assays revealed that 3 h after TSST‐1, PBMC were neither activated nor responsive to in vitro restimulation, even when IL‐2 was added. In contrast, 7 days later, PBMC and spleen cells were anergic: showing no response to TSST‐1 but a vigorous response upon addition of IL‐2. The results presented extend our understanding of the pathophysiology of toxic and septic shock as a result of superantigen toxin‐producing Staphylococcus aureus. Demonstration of compartmentalization of the response proves that erroneous conclusions could be drawn by the exclusive analysis of PBMCs. The results reveal further that in nonresponsiveness to the antigen, different immunological mechanisms may be operational. Measurements of the induction of cytokine gene activation provide important complementary information to that of serum cytokine levels.
The Collected Works of AM Turing : Mechanical Intelligence

Many leading analysts would agree that, had it not been for multimodal epistemologies, the development of congestion control might never have occurred. In this work, we disprove the synthesis of the lookaside buffer. In this position paper we confirm not only that the infamous symbiotic algorithm for the visualization of digital-to-analog converters by Z. Nehru runs in Θ(2) time, but that the same is true for ebusiness.
Does Human Warmth Matter ? – An Experiment on User Profiles in Initial Business Interaction

Social Presence (SP), i.e. the feeling of human warmth, is usually treated as a desirable outcome of interpersonal communication. This is in line with the current trend of Online Social Networks (OSN) where social interaction on basis of user profiles is being promoted. The rise of OSNs also includes enterprise software. While previous studies in this field deal with the question of adoption, the role of the user profile has been neglected. This study addresses this research gap by focusing on user profiles and evaluating the effect on SP, Trust and Enjoyment in an initial business interaction. The findings suggest that for an information exchange task, user profiles do not help to create SP. Thus, the potential of OSNs in enhancing communication may be constrained. Due to some limitations of this laboratory experiment and as part of future research, it is suggested to re-evaluate the findings in more natural settings.
Learning through teaching: Peer-mediated instruction in minimally invasive education

The current paper provides insight into the learning strategies adopted by children working at Minimally Invasive Education (MIE) Learning Stations. Previous research has clearly indicated the attainment of basic computer literacy by groups of young children in the age groups of 7–14 years. This learning takes place due to the emergence and development of group social processes, an aspect crucial for achieving basic computing skills. The paper describes the process of socially shared understanding and learning as being crucial to individual learning. It is to be noted that this approach of socially shared learning does not challenge the analysis of the individual level of processing; it maintains that individual learning is vital in any learning context, but insufficient to build the psychology of learning. MIE research is of the view that young children learn through interaction with others, particularly peers as it provides an important context for social and cognitive learning. For it is in this way that children make sense of their own experience and environment. Hence, schools are not the only privileged sites of learning.
Musculoskeletal responses to high- and low-intensity resistance training in early postmenopausal women.

PURPOSE The purpose of this study was to compare the effects of a high-load (80%, 1-repetition maximum (RM), 8 reps) and a high-repetition (40%, 1-RM, 16 reps) resistance training protocol on muscular strength and bone mineral density (BMD) in early postmenopausal, estrogen-deficient women. The 6-month programs were matched initially for training volume (3 sets, 3 d x wk(-1)) for 12 exercises selected to specifically load the spine and hip. METHODS Subjects included 25 women (41-60 yr) who were matched by spine BMD then randomly assigned to either the high-load (HL, N = 10), high-repetition (HR, N = 7), or control (C, N = 8) groups. Dietary calcium intakes were supplemented to approximately 1500 mg x d(-1). Total body, spine, and hip BMD (DXA, Lunar Model DPX-IQ), upper and lower body muscular strength, and biochemical markers of bone turnover were measured at baseline and after 6 months of training. RESULTS There were no group differences in the baseline measures. Both training groups showed similar increases in biceps (20%) and rectus femoris (28-33%) cross-sectional areas, in lower body strength (approximately 30%) and in hip strength (37-40%). HL showed greater improvements in upper body strength (HL 25%, HR 16%). Neither training group experienced significant increases in spine or hip BMD, although the HL total body BMD tended to decrease (-1.1%+/-0.4, P = 0.054) after training. Osteocalcin tended to increase (P = 0.08) in all groups after training, and the % change in osteocalcin was positively related to % changes in the total hip (r = 0.41, P = 0.048) and the trochanter (r = 0.42, P = 0.04) BMD. CONCLUSION The high-load and high-repetition resistance training protocols were both effective in improving muscular strength and size in postmenopausal women, indicating low-intensity resistance training can be beneficial for the muscular fitness in women for whom high-intensity exercise is contraindicated.
Digital Competition Game to Improve Programming Skills

The aim of this paper is to describe a digital game with an educational purpose in the subject of computer programming, which enables students to reinforce and improve their abilities on the concepts of sequencing, defined iteration and nesting. For its design, a problem solving approach was followed and a score comparing mechanism was implemented in order to encourage students to analyze their solutions and look for better ones. To validate the game, a study with a 123 students sample was made, which did not only demonstrate students interest on the approach but also its educational effectiveness.
Update on Anticytokine Treatment for Asthma

Current advances in the knowledge of asthma pathobiology suggest that anticytokine therapies can be potentially useful for the treatment of this complex and heterogeneous airway disease. Recent evidence is accumulating in support of the efficacy of anti-IL-4, anti-IL-5, and anti-IL-13 drugs. Therefore, these new developments are now changing the global scenario of antiasthma therapies, especially with regard to more severe disease. Current findings referring to variability of individual therapeutic responses highlight that the different asthma subtypes need to be well characterized, in order to implement phenotype-targeted treatments which in the near future will hopefully be mainly based on cytokine-directed biologics.
The QWERTY Effect: How typing shapes word meanings and baby names

Filtering words through our fingers as we type appears to be changing their meanings. On average, words typed with more letters from the right side of the QWERTY keyboard are more positive in meaning than words typed with more letters from the left: This is the QWERTY effect (Jasmin & Casasanto, 2012), which was shown previously across three languages. In five experiments, here we replicate the QWERTY effect in a large corpus of English words, extend it to two new languages (Portuguese and German), and show that the effect is mediated by space-valence associations encoded at the level of individual letters. Finally, we show that QWERTY appears to be influencing the names American parents give their children. Together, these experiments demonstrate the generality of the QWERTY effect, and inform our theories of how people’s bodily interactions with a cultural artifact can change the way they use language.
Search for vertical stratification of metals in atmospheres of blue horizontal-branch stars

Context. The observed abundance peculiarities of many chemical species relative to the expected cluster metallicity in blue horizontalbranch (BHB) stars presumably appear as a result of atomic diffusion in the photosphere. The slow rotation (typically v sini 11 500 K supports this idea since the diffusion mechanism is only effective in a stable stellar atmosphere. Aims. In this work we search for observational evidence of vertical chemical stratification in the atmospheres of six hot BHB stars: B84, B267 and B279 in M 15 and WF2-2541, WF4-3085 and WF4-3485 in M 13. Methods. We undertake an abundance stratification analysis of the stellar atmospheres of the aforementioned stars, based on acquired Keck HIRES spectra. Results. We have found from our numerical simulations that three stars (B267, B279 and WF2-2541) show clear signatures of the vertical stratification of iron whose abundance increases toward the lower atmosphere, while the other two stars (B84 and WF4-3485) do not. For WF4-3085 the iron stratification results are inconclusive. B267 also shows a signature of titanium stratification. Our estimates for radial velocity, v sini and overall iron, titanium and phosphorus abundances agree with previously published data for these stars after taking the measurement errors into account. The results support the hypothesis regarding the efficiency of atomic diffusion in the stellar atmospheres of BHB stars with Teff > 11 500 K.
A Curvilinear Trend in Naming Errors as a Function of Early Vocabulary Growth

This research examines changes in word retrieval and naming during a developmental period in which there is a substantial increase in productive vocabulary. That increase generally occurs when children have between 50 to 150 words in productive vocabulary. We examined children's naming errors in two studies for what these errors could tell us about the emerging lexicon. The method we used for eliciting spontaneous naming was picture book reading by the parent. In Experiment 1, 12 children were followed longitudinally at three-week intervals from 15 to 22 months. Parent diaries were used as a measure of vocabulary growth. Experiment 2 used a cross-sectional design to compare the naming errors of 60 children assigned to one of three vocabulary ranges. Measures of vocabulary size were based on the MacArthur Communicative Development Inventory. In both experiments we found a sharp increase in naming errors in the picture book task that was coincident with sudden changes in productive vocabulary. These naming errors were often perseverative in nature and appear to reflect interference in the retrieval process from previously retrieved words. The results suggest that these errors in naming are a consequence of changes in lexical processing that occur with rapid growth of productive vocabulary and concurrent increased rates of speaking.
Nutrient Supplementation for Age-related Macular Degeneration, Cataract, and Dry Eye

There have been enormous advances in the past decade for the treatment of age-related macular degeneration (AMD); however, these treatments are expensive and require frequent follow-up and injections which place a tremendous burden on both the healthcare system and patients. Consequently, there remains considerable interest in preventing or slowing the progression of AMD requiring treatment. Epidemiological studies have shown that diet is a modifiable AMD risk factor, and nutrient modification is a particularly appealing treatment for AMD due to the perceived universal benefit and relatively low expense. Recently, the age-related eye disease study part two (AREDS2) was concluded and demonstrated further benefit with the addition of lutein and zeaxanthin as a replacement for the β-carotene of the previous generation formulation. The addition of omega-3 essential fatty acids did not show an added benefit. This review aims to highlight some of the evidenced based body of knowledge that has been accumulated from recent studies regarding the use of nutritional supplements and their effect on AMD, cataracts, and dry eyes.
Storytelling in Amy Tan’s The Bonesetter’s Daughter: belonging and the transnationality of home in older age

ABSTRACT Amy Tan’s The Bonesetter’s Daughter is a fictional account of a Chinese American woman and her mother, a first-generation migrant, who is negotiating dementia in later life. Analysis of diasporic novels can provide insight into migrant belonging, especially the emotional geographies of home and emotional subjectivities of ageing that are not commonly or easily elucidated even by qualitative interviewing methods. This article examines Tan’s construction of ageing as an intergenerational, cultural and emotional process, and highlights the role of storytelling as an everyday home-making practice through which the transnationality of home in older age becomes evident.
Southern development discourse for Southern Africa: linguistic and cultural imperatives

ABSTRACT Although Africa’s dependency on the West is understandably rooted in economic and political developments that have a long historical trajectory, it is also an epistemological issue. The current push for a shift away from traditional dependency on Western countries is untenable as Africa’s economic development pathways continue to be informed by Euro-American epistemologies. This stifles creative and innovative thinking in ways other than those from the Global North. The majority of African countries have looked East for possible solutions to this paradox. However, Eastern models alone cannot be a viable solution either. They need to be adapted to local African cultural conditions and, most importantly, they need to be used alongside local African epistemologies. With specific reference to southern Africa, this article argues that both the Northern and Eastern traditions of knowledge should be seen as part of a diverse global system of epistemologies and that they should be complemented by what I call Southern development discourse. I highlight the promises and affordances of African linguistic diversity and cultural resources in advancing the argument that creativity and innovation are guaranteed when local contextual particularities and cultural specificities are part of the underpinning pillars of policy frameworks on development.
