Public School Teachers' Perceptions of Administrative Support and its Mediating Effect on Their Job Satisfaction and Intent to Stay in Teaching

Due to a high rate of teacher attrition currently being experienced in public schools, a teacher shortage may be looming in the near future. Research shows that attrition rates are highest among novice teachers. In part, teacher attrition has also made it increasingly difficult for schools to meet the “highly qualified” requirement of the No Child Left Behind Act of 2001. Past efforts to reverse this trend have concentrated on increasing the supply of qualified teachers; however, more recent studies have shown that the solution lies partially in raising retention rates. Research has identified several reasons teachers have left the profession, such as, low salary, student misbehavior and working conditions, including administrative support. Another common thread among teachers who leave the profession has been dissatisfaction with working conditions in their school. This study examined the relationship between teachers’ intent to stay in teaching, teachers’ job satisfaction, perceived administrative support, teaching experience, perceived student behavior, and teachers’ satisfaction with their salaries. After the conduct of a preliminary descriptive analysis, a hypothesized path model was employed through the use of four different samples derived from the 2003-04 Schools and Staffing Survey, Public School Teacher Questionnaire (Form SASS-4A). The first sample was the combined environmental setting. The second, third, and fourth sub-samples were urban, urban fringe, and rural samples, respectively, as identified by the respondent. Based on the path analysis, perceived administrative support, teaching experience, perceived student behavior, and teachers’ satisfaction with their salary were identified as significant predictors of teachers’ job satisfaction and intent to stay in teaching. Administrative support was the most significant predictor of teachers’ job satisfaction, while teachers’ job satisfaction was the most significant predictor of teachers’ intent to stay in teaching. The path analysis also confirmed that perceived administrative support mediates the effect of teaching experience, perceived student behavior, and teachers’ satisfaction with their salary relative to both teachers’ job satisfaction and intent to stay in teaching. No significant differences were found among the sample and their sub-samples based on the environmental setting of the school.
Swipp-a multicomputer framework for bulk synchronous parallel computing

A computer framework feasible for developing parallel systems according to the Bulk Synchronous Parallel (BSP) computing model is described: Switched Interconnection of Parallel Processors (Swipp). Demanding applications can be described as directed graphs where the interdependent subtasks constitute the nodes. The tasks are predistributed by a system master, Computer Executive Engine (GEE), to a set of heterogeneous computing nodes. Each computing node has a preprogrammed secondary control processor attached for performing communication and run-time tasks, thus allowing primary processors of various kinds and programming styles. Synchronization of a bulk of subactivities is done in locksteps by the GEE. Basic features are modelled by the Ptolemy framework and prototype modules are being implemented.
A local tone mapping operator for high dynamic range images

In this paper, we present a new tonemapping operator to display high dynamic range image onto conventional displayable devices and printers. In our work, a new tone map algorithm, derived from the Contrast Limited Adaptive histogram Equalization (CLAHE) technique is presented. Due to different luminance intervals could result in overlapped reaction on the limited response in limited response range of visual system, we use scenes region splitting and merging to segment the scaled luminance, L(x, y) and perform the CLAHE in each segment with different clip limit in order to extending our visual response range to cope with the full dynamic range of high contrast. Until now, there is no fix standard of objective evaluation available to measuring the quality of displayed High Dynamic Range (HDR) images because it is difficult to know how the light or dark the image should be displayed to faithful to the original HDR image. As the result, the main evaluation is based on human's subjective evaluation. In this paper, we consider this to evaluate the performances with different tone mapping method.
Short stature is associated with coronary heart disease: a systematic review of the literature and a meta-analysis.

AIMS The aim of this study was to assess the relationship between short stature and coronary heart disease (CHD) morbidity and mortality. METHODS AND RESULTS We performed a systematic search from MEDLINE, PREMEDLINE, and All EBM Reviews as well as from a reference list of relevant articles. We used SPICO (Study design, Patient, Intervention, Control-intervention, Outcome) criteria. The methodological quality of studies was analysed by modified Borghoust criteria. From a total of 1907 articles, we selected 52 studies comprising population-based follow-up studies and patient cohorts followed after a CHD event, as well as case-control studies with height either as a continuous or categorical variable, totalling 3 012 747 individuals. The short ones were below 160.5 cm and tall ones over 173.9 cm on average. Among the shortest height category, the relative risks were 1.35 (95% CI 1.25-1.44) for all-cause mortality, 1.55 (1.37-1.74) for all cardiovascular disease (CVD) mortality, 1.49 (1.33-1.67) for CHD, and 1.52 (1.28-1.81) for myocardial infarction when compared with those within the highest height category. The mean relative risk was 1.46 (1.37-1.55). Short stature was associated with increased cardiovascular morbidity and mortality in both genders. CONCLUSION The relationship between short stature and CVD appears to be a real one. On the basis of comparison, adults within the shortest category had an approximately 50% higher risk of CHD morbidity and mortality than tall individuals.
rhoIndex – Designing and Evaluating an Indexing Structure forGraph Structured Data

An own design of an indexing structure for general graph structured data called rhoIndex that allows an effective processing of special path queries is presented. These special queries represent for example a search for all paths lying between two arbitrary vertices limited to a certain path length. The rhoIndex is a multilevel balanced tree structure where each node is created with a certain graph transformation and described by modified adjacency matrix. Hence, rhoIndex indexes all the paths to a predefined length l inclusive. The search algorithm is then able to find all the paths shorter than or having the length l and some of the paths longer then the predefined l lying between any two vertices in the indexed graph. The designed search algorithm exploits a special graph structure, a transcription graph, to compute the result using the rhoIndex. We also present an experimental evaluation of the process of creating the rhoIndex on graphs with different sizes and also a complexity evaluation of the search algorithm that uses the rhoIndex.
Discovering the Genetics of Complex Disorders Through Integration of Genomic Mapping and Transcriptional Profiling

Discovering the genes that contribute to complex polygenic diseases represents a significant challenge. Investigating the structural genetic variations associated with these disorders may not be sufficiently informative about vulnerability genes modulated by the environment. Characterizing gene expression patterns does not identify the primary differences in gene structure. The convergence of global screening of gene expression patterns with extensive structural genomic information may be necessary to identify the gene clusters that contribute to these pervasive diseases. These integrative efforts, though promising, are in their early phases and will require further refinement.
The Connection between Gamma-Ray Bursts and Extremely Metal-poor Stars: Black Hole-forming Supernovae with Relativistic Jets

Long-duration gamma-ray bursts (GRBs) are thought to be connected to luminous and energetic supernovae (SNe) called hypernovae (HNe), resulting from the black hole (BH)-forming collapse of massive stars. For recent nearby GRBs 060505 and 060614, however, the expected SNe have not been detected. The upper limits to the SN brightness are about 100 times fainter than GRB-associated HNe (GRB-HNe), corresponding to the upper limits to the ejected 56Ni masses of M(56Ni) ~ 10-3 M☉. SNe with a small amount of 56Ni ejection are observed as faint Type II SNe. HNe and faint SNe are thought to be responsible for the formation of extremely metal-poor (EMP) stars. In this Letter, a relativistic jet-induced BH-forming explosion of the 40 M☉ star is investigated and hydrodynamic and nucleosynthetic models are presented. These models can explain both GRB-HNe and GRBs without bright SNe in a unified manner. Their connection to EMP stars is also discussed. We suggest that GRBs without bright SNe are likely to synthesize M(56Ni) ~ 10-4 to 10-3 M☉ or ~10-6 M☉.
Electronically Tunable Quadrature Oscillator Using Current-controlled Voltage Conveyors

A translinear-based bipolar realization of the current-controlled voltage conveyor (CCVC) is described. An electronically tunable quadrature oscillator is then proposed which uses only three proposed CCVCs and two grounded capacitors for its realization. The proposed oscillator circuit provides two quadrature sinusoidal outputs with 90° phase difference. The oscillation condition and the oscillation frequency are independently controllable by electronic means through adjusting the external dc bias current. PSPICE simulation results that confirm the theoretical are also given and discussed.

A Comparative and Overview Analysis of Elliptic Curve Cryptography over Finite Fields

Recently, Finite Fields are the most important security mathematical function in the area of elliptic curve cryptography. In this paper, we classify the finite fields into a prime field and a binary field. The proposed approach offers solution to solve the real time implementation based on the finite fields. One such important property is point doubling that has not been focused previously. Finite fields are used to implement the process in a secure way. It is tedious work for the hackers to hack the function, which is based on elliptic curves over finite fields. Therefore, it is more efficient in Elliptic curves and performance and give a one example for application on EC signature. Finally, an serious discussion about the comparison between ECC and other cryptography algorithm is attempted to shape this article.
Effects of labeling the "drug-abuser": an inquiry.

primary objective is to provide critical reviews of research problem areas and techniques, the content of state-of-the-art conferences, integrative research reviews and significant original research. Its dual publication emphasis is rapid and targeted dissemination to the scientific and professional community. ii FOREWORD When this monograph was originally conceived (1973), Institute scientists and others interested in the problem of drugs were very much concerned about the impact of being arrested or otherwise identified as a "drug abuser" on the self concept and subsequent behavior of those adolescents so labeled. Although there was little data to provide convincing empirical support for our impressions, it seemed reasonable to assume that such labeling might have serious implications. In estranging the labeled individual from his peers and creating a climate of expectation both in himself and in others, this process of being labeled a drug user seemed likely to encourage further a profound sense of social alienation and a still greater tendency to use drugs. Because of the potential importance of this issue in developing a more rational approach to illicit drug use, the Institute commissioned the Research Triangle Institute to study the feasibility of a study in this area. One outcome of that work was the decision not to attempt a larger scale study of labeling. It became clear that both the drug-use picture and society's response to it were changing far too rapidly to mount a longitudinal study of the type originally considered. While personal possession of marihuana was originally a felony in many states, there has been an increasing tendency to make it a misdemeanor or not to prosecute individuals found possessing small quantities. Indeed as of this date (February, 1976), six states have elected to decriminalize completely personal possession of small amounts of cannabis. Moreover , what was once statistically deviant behavior has now become the statistical norm (53% of the 18-25 age group had used marihuana one or more times by 1975) still further altering the way in which drug using behavior is viewed both by users themselves and by others in the community. Although the study originally contemplated no longer appears to be feasible, the thinking that went into reviewing the problem is of continuing interest. We believe the excellent review done by Dr. Williams deserves a larger audience and will be valuable to many interested in the possible impact of labeling on adolescents and on the development of …
First evidence of some dinoflagellates reducing male copepod fertilization capacity

Evidence is presented that hatching failure in Temora stylifera eggs can depend on poor sperm quality. Three dinoflagellate diets, Prorocentrum micans, Gymnodinium sanguinium, and Gonyaulax polyedra, significantly modified spermatophore production and reduced the fertilization capacity of male sperm after 6–12 d of continuous feeding. Two other diets, the dinoflagellate P. minimum and the prymnesiophycean Isochrysis galbana, had no effect on hatching success, which remained high (>;89%) and stable with time. A reduction in fertilization capacity was neither due to maternal effects nor to male age since hatching success returned to normal upon the introduction of freshly caught wild males or males conditioned with a good diet such as P. minimum for the same length of time as couples fed with the poor diets, P. micans, G. sanguinium, and G. polyedra. Confocal microscope images of unhatched eggs colored with a nucleus‐specific fluorescent dye confirmed that these eggs had not been fertilized. Experiments with Calanus helgolandicus females, which did not require reinsemination and which were fed the same diets that induced hatching failure in T. stylifera, showed no change in hatching success with time.
The Importance of Recording Data in the Agricultural Sector for Decision-Making

In order to better decision making in the agricultural sector, it is necessary to the existence of adequate records or documentation base containing all changes relating to the implementation of business activities on the farm. Taking into account the characteristics of biological transformations, which are characterized by agricultural production, it is necessary to monitor and record the effects arising from the implementation of activities on the farm. Also, the analysis of the invested funds or inputs and realized value of production-outputs, are of importance for understanding the results of operations in this sector. Identification and analysis of the financial results of farms is in direct conjunction with appropriately-designed system of accounting information. The research subjects, presented in this paper, are theoretical, conceptual, methodological and applicative aspects of accounting information system, in order to raise the quality of governance at macro and micro level in the field of agriculture. The importance of accounting informing is reflected in the continuous monitoring of production and financial indicators on the farms. The basic premise for this is the existence of high-quality accounting records on farms, in order to create high-quality information base for the analysis of the agricultural sector.
Gasterophilus (Diptera, Gasterophilidae) infestation of equids in the Kalamaili Nature Reserve, China

We investigated infections with Gasterophilus spp. in three equids within the Kalamaili Nature Reserve (northern China). We conducted necropsies on 6 Przewalski’s horses (Equus ferus przewalskii) and 6 Mongolian wild asses (Equus hemionus) and administered ivermectin to 10 overwintering domestic horses to expel parasites during winter periods. All 22 equids studied (100%) were infested with Gasterophilus spp. and a total of 17,225 larvae were collected. These included six species: G. haemorrhoidalis, G. inermis, G. intestinalis, G. nasalis, G. nigricornis, and G. pecorum. The mean intensity of Gasterophilus spp. larvae was 1904 in Przewalski’s horses, 780 in Mongolian wild asses, and 113 in domestic horses. Gasterophilus pecorum was the most abundant species in all three equids. Przewalski’s horses, a reintroduced species, had a significantly higher intensity of Gasterophilus spp. than the Mongolian wild ass, indicating greater susceptibility to parasites in its ancestral home.
A multi-agent open architecture for a TV recommender system: a case study using a Bayesian strategy

In this paper we present a recommender system of personalized TV contents, called AVATAR, for which we propose a modular multiagent architecture, that combines different knowledge inference strategies (such as Bayesian techniques, profiles matching and semantic reasoning). We focus on the description of one of these strategies, the naive Bayesian classifiers, explaining an example in the context of personalized digital television. In order to represent the knowledge in the television domain, we have developed TV contents ontology, to infer new data from the known information. Besides, the TV-anytime specification has been used referred to the description of contents and the management of user preferences and their activity logs. The proposed recommender system has been conceived as an application conforming to multimedia home platform (MHP) standard, to be distributed over the broadcast transport stream that is tuned by the user receiver.
On Goodput and Energy Measurements of Network Coding Schemes in the Raspberry Pi

Given that next generation networks are expected to be populated by a large number of devices, there is a need for quick deployment and evaluation of alternative mechanisms to cope with the possible generated traffic in large-scale distributed data networks. In this sense, the Raspberry Pi has been a popular network node choice due to its reduced size, processing capabilities, low cost and its support by widely-used operating systems. For information transport, network coding is a new paradigm for fast and reliable data processing in networking and storage systems, which overcomes various limitations of state-of-the-art routing techniques. Therefore, in this work, we provide an in-depth performance evaluation of Random Linear Network Coding (RLNC)-based schemes for the Raspberry Pi Models 1 and 2, by showing the processing speed of the encoding and decoding operations and the corresponding energy consumption. Our results show that, in several scenarios, processing speeds of more than 80 Mbps in the Raspberry Pi Model 1 and 800 Mbps in the Raspberry Pi Model 2 are attainable. Moreover, we show that the processing energy per bit for network coding is below 1 nJ or even an order of magnitude less in these scenarios.
Feminist Statement on Guaranteed Living Income

Every issue of Canadian Woman Studies/les cahiers de h fernme involves gathering women from various locations to meet and read together and discuss the potential contents. Always that is a useful educational opportunity for those on the editorial board, for students, for the profession of women's studies, for activists, and for the women's movement as a whole. But in these times of great and increasing pressure on women and their activism, more is necessary. Editorial board members, potential authors, and readers are all feeling under attack. Women's places in the academy, centres, projects, and wings of the movement as well as women's livelihood, dignity, and autonomy are finan~
Isolation of Early Neurogenesis Genes with Xenopus cDNA Microarray

Neurogenesis is the process that develops neuroectoderm from ectoderm. Bone morphogenetic protein (BMP) inhibition in ectodermal cells is necessary and sufficient for neurogenesis in Xenopus embryos. To isolate genes involved in early neurogenesis, Xenous Affymetrix gene chips representing 14,400 genes were analyzed in early stage of neuroectodermal cells that were produced by inhibition of BMP signaling with overexpression of a dominant-negative receptor. We identified 265 candidate genes including 107 ESTs which were newly expressed during the early neurogenesis by blocking BMP signaling. The candidates of 10 ESTs were selected and examined for upregulation in neuroectoderm. Five EST genes were confirmed to be upregulated in neuroectoderm and examined for time-dependent expression patterns in intact embryos. Two EST genes were cloned and identified as a homology of CYP26c (Xl.1946.1.A1_at) and Kielin containing VWC domain (Xl.15853.1.A1_at). One of them, CYP26c, was further characterized for its transcriptional regulation and role of anterior-posterior patterning during neurogenesis. Taken together, we analyzed and characterized genes expressed in early neurogenesis. The results suggest that neurogenesis by inhibition of BMP provides useful system to isolate genes involved in early events of neurogenesis during early vertebrate embryogenesis.
