Achievement Goals and Their Relations to Children's Disruptive Behaviors in an After-School Physical Activity Program.

This study used a trichotomous achievement goal model to explore and describe what actually happened in terms of students’ achievement goals and disruptive behaviors in an after-school physical activity program. Participants included 158 students in grades 3–6. They completed questionnaires assessing their achievement goals and disruptive behaviors. Nine of the participants were also selected and observed for disruptive behaviors. Students reported higher scores on the mastery goal than they did on the performance-approach and performance-avoidance goals. The mastery goal was negatively related to students’ self-reported low engagement, whereas the performance-approach and performance-avoidance goals were positively related to students’ self-reported disruptive behaviors. Overall, findings of the study provide empirical support for the trichotomous achievement goal model as a viable theoretical framework in the study of students’ disruptive behaviors in after-school physical activity settings.
Biosynthesis of an unglycosylated envelope glycoprotein of Rous sarcoma virus in the presence of tunicamycin

Cells stably infected with Rous sarcoma virus were treated with tunicamycin to prevent the glycosylation of the precursor (pr92gp) to the two viral envelope glycoproteins gp85 and gp35. Pretreatment of the cells for 4 h with the antibiotic resulted in a 90% reduction in [3H]mannose incorporation into total cellular glycoproteins, intracellular viral glycoproteins, and released virus particles. Protein synthesis and virus particle formation were not significantly affected by the treatment. A new polypeptide made in the presence of the drug was identified by immunoprecipitation of pulse-labeled cell lysates with monospecific anti-gp85 and anti-gp35 sera. This polypeptide, migrating on sodium dodecyl sulfate-polyacrylamide gels as a molecule of 62,000 daltons (pr62), contained no [3H]mannose, was labeled with [S35]methionine and [3H]arginine, could not be chased into the higher-molecular-weight glycosylated form, and contained the same [3H]arginine tryptic peptides as pr92gp. The unglycosylated pr62 was still detectable 2 h after the pulse labeling of the cells. The lack of glycosylation of pr62 did not seem to reduce its stability. No clear evidence for the incorporation of this molecule or its cleavage products into viral particles could be obtained. To code for an envelope polypeptide of 62,000 daltons, only about 1,500 nucleotides or 15% of the total coding capacity of the virus are needed.
Work absence as a function of a national traumatic event: The case of Prime Minister Rabin's assassination

Most research on absenteeism has focused on the effects of individual and work-related factors, to the exclusion of the effects of societal and political events external to the individual and his/her specific work conditions. The purpose of this study was to investigate the relationship between the emotional reaction to the assassination of Prime Minister Rabin in Israel and work absenteeism during the period following the assassination. It was hypothesized that: (1) emotional reaction is positively related to absenteeism; (2) this relationship is stronger among female employees than among male employees; and (3) this relationship is stronger for individuals who are pessimistic about the future as opposed to those who are optimistic. These hypotheses were supported by data collected from a random sample of 199 working adults.
Effect of pravastatin on progression of coronary atherosclerosis in patients after coronary artery bypass surgery.

BACKGROUND Although the anti-atherosclerotic effects of HMG-CoA reductase inhibitors are well known, their specific effect on saphenous vein grafts after coronary artery bypass graft (CABG) operation is not well documented and has not been studied in Japan, so the aim of the present prospective randomized controlled study involving 27 Japanese institutions was to investigate the effects of pravastatin on the progression of atherosclerosis in such grafts and native coronary arteries after CABG. METHODS AND RESULTS A total of 303 patients who had undergone CABG were randomly assigned to either the pravastatin group (n =168) or the control group (n = 167). Paired coronary angiograms were obtained at baseline and at the end of 5-year follow-up in 182 (60%) patients. The low-density lipoprotein cholesterol concentration significantly decreased in the pravastatin group from 141.4 mg/dl to 113.7 mg/dl (-19.6%), compared with 141.1 mg/dl to 133.7 mg/dl (-5.2%) in the control group (p < 0.001). Although there was no significant difference in the quantitative coronary angiography measurements between the 2 groups, the global change score indicated a significant pravastatin-mediated reduction in plaque progression (p < 0.01). CONCLUSIONS Pravastatin can potentially reduce atherosclerotic progression in both the bypass graft and native coronary arteries of patients after CABG.
ESPRESSO-SIGNATURE: A New Exact Minimizer for Logic Functions

We present a new algorithm for exact two-level logic optimization which radically improves the Quine-McCluskey (QM) procedure. The new algorithm derives the covering problem directly and implicitly without generating the set of all prime implicants. It then generates only those prime implicants involved in the covering problem. We represent a set of primes by the cube of their intersection. Therefore, the unique set of sets of primes which forms the covering problem can be implicitly represented by a set of cubes which forms a minimum canonical cover. We obtain the minimum canonical cover starting from any initial cover and then derive the covering problem. The method is effective; it improves on the runtime and memory usage of ESPRESSO-EXACT by average factors of 1.78 and 1.19 respectively on the 114 of 134 benchmark examples that could be completed by ESPRESSO-EXACT. Of the remaining 20 hard problems, we solve 14 exactly. For 3 of the remaining 6 the covering problem is derived but it could not be solved exactly.
Opportunities and Obstacles for Good Work in Nursing

Good work in nursing is work that is scientifically effective as well as morally and socially responsible. The purpose of this study was to examine variables that sustain good work among entering nurses (with one to five years of experience) and experienced professional nurses despite the obstacles they encounter. In addition to role models and mentors, entering and experienced nurses identified team work, cohesiveness and shared values as levers for good work. These nurses used prioritization, team building and contemplative practices to overcome obstacles. Entering professional nurses tended to avoid conflict in the work setting. Experienced nurses reported forming teams of decision makers who share similar values to resolve conflict. These findings have implications for nurse education and nursing practice. Reflection on the importance of values and virtue in sustaining good work is important. Entering professional nurses should be encouraged to seek positive role models and reflect on the lessons that can be learned from experienced exemplary nurses.
Coding strategies for UWB interference-limited peer-to-peer networks

Abstract In this work we study the achievable rates of memoryless sig-naling strategies adapted to UltraWideBand (UWB) multi-path fading channels. We focus on strategies which do nothave explicit knowledge of the instantaneous channel realiza-tion, but may have knowledge of the channel statistics. Weevaluate the average mutual information of general binaryash-signaling and achievable rates for m -PPM as a functionof the channel statistics. Finally, we briey examine the ro-bustness of ash-signaling for interference-limited systems.NotationsThroughout the paper, small letters 0 a will be used for scalars,capital letters 0 A for vectors, and bold capital letters 0 A formatrices.1. IntroductionIn this work, we consider achievable rates for transmissionstrategies suited to Ultra-wideband (UWB) systems and focusnon-coherent receivers (i.e. those which do not perform chan-nel estimation, but may have prior knowledge of the second-order channel statistics). Here we take a UWB system to beloosely de ned as any wireless transmission scheme that occu-pies a bandwidth between 1 and 10 GHz and more than 25%of it's carrier frequency in the case of a passband system.The most common UWB transmission scheme is based ontransmitting information through the use of short-term im-pulses, whose positions are modulated by a binary informa-tion source [1]. This can be seen as a special case of ashsignaling coined by Verdu in [6]. Similar to direct-sequencespread-spectrum, the positions can further be modulated bya non-binary sequence (known as a time-hopping sequence )for mitigating inter-user interference in a multiuser setting[2]. This type of UWB signaling is a promising candidatefor military imaging systems as well as other non-commercialsensor network applications because of its robustness to in-terference from signals (potentially from other non-UWB sys-
Do consistent corporate cultures have better business performance? Exploring the interaction effects

Past research has shown a close connection between organizational culture and effectiveness, but nearly all of this research has examined the direct effects of culture on performance outcomes. In contrast, this article examines the idea that the effects of cultural consistency on organizational performance may differ depending on the levels of other culture traits. Data from 88,879 individuals in 137 public companies using the Denison Organizational Culture Survey were paired with three objective measures of organizational performance and used to examine the interaction effects of consistency with mission, adaptability, and involvement. Consistency shows a significant positive interaction with all three traits in predicting market-to-book ratios and sales growth. Firms that are both consistent and adaptable, for example, are high performers. In contrast, the results show a significant negative interaction when predicting return on assets. The implications of these results are discussed with respect to future culture and effectiveness research.
Active Galactic Nuclei in the Sloan Digital Sky Survey. II. Emission-Line Luminosity Function

The emission-line luminosity function of active galactic nuclei (AGNs) is measured from about 3000 AGNs included in the main galaxy sample of the Sloan Digital Sky Survey within a redshift range of 0 < z < 0.15. The Hα and [O III] λ5007 luminosity functions for Seyfert galaxies cover a luminosity range of 105–109 L⊙ in Hα, and the shapes are well fitted by broken power laws, without a turnover at fainter nuclear luminosities. Assuming a universal conversion from emission-line strength to continuum luminosity, the inferred B-band magnitude luminosity function is comparable to both the AGN luminosity function of previous studies and the low-redshift quasar luminosity function derived from the Two-Degree Field redshift survey. The inferred AGN number density is approximately one-fifth of all galaxies, and about 6 × 10-3 of the total light of galaxies in the r band comes from nuclear activity. The numbers of Seyfert 1 and Seyfert 2 galaxies are comparable at low luminosity, while at high luminosity, Seyfert 1 galaxies outnumber Seyfert 2 galaxies by a factor of 2–4. In making the luminosity function measurements, we assume that the nuclear luminosity is independent of the host galaxy luminosity, an assumption we test a posteriori and show to be consistent with the data. Given the relationship between black hole mass and host galaxy bulge luminosity, the lack of correlation between nuclear and host luminosity suggests that the main variable that determines the AGN luminosity is the Eddington ratio, not the black hole mass. This appears to be different from luminous quasars, which are most likely to be shining near the Eddington limit.
Assessing the Dimensionality and Structure of the Consumption Experience: Evaluation, Feeling, and Satisfaction

This article examines the underlying dimensionality of three aspects of the post-consumption experience—product evaluation, product-elicited affect, and product satisfaction. In addition, the article integrates these concepts through a suggested causal framework. Students evaluated either a high- or a low-involvement product in current use, reported affective responses evoked by it, and assessed their levels of product-derived satisfaction. Analysis shows that two primary dimensions of product evaluation—utilitarian and hedonic judgment—can be viewed as causally antecedent to two dimensions of affect—pleasantness and arousal—and to product satisfaction. Implications of the conceptual framework and empirical findings for the study of consumption events are discussed.
Association of single-nucleotide polymorphisms of the tau gene with late-onset Parkinson disease.

CONTEXT The human tau gene, which promotes assembly of neuronal microtubules, has been associated with several rare neurologic diseases that clinically include parkinsonian features. We recently observed linkage in idiopathic Parkinson disease (PD) to a region on chromosome 17q21 that contains the tau gene. These factors make tau a good candidate for investigation as a susceptibility gene for idiopathic PD, the most common form of the disease. OBJECTIVE To investigate whether the tau gene is involved in idiopathic PD. DESIGN, SETTING, AND PARTICIPANTS Among a sample of 1056 individuals from 235 families selected from 13 clinical centers in the United States and Australia and from a family ascertainment core center, we tested 5 single-nucleotide polymorphisms (SNPs) within the tau gene for association with PD, using family-based tests of association. Both affected (n = 426) and unaffected (n = 579) family members were included; 51 individuals had unclear PD status. Analyses were conducted to test individual SNPs and SNP haplotypes within the tau gene. MAIN OUTCOME MEASURE Family-based tests of association, calculated using asymptotic distributions. RESULTS Analysis of association between the SNPs and PD yielded significant evidence of association for 3 of the 5 SNPs tested: SNP 3, P =. 03; SNP 9i, P =. 04; and SNP 11, P =. 04. The 2 other SNPs did not show evidence of significant association (SNP 9ii, P =.11, and SNP 9iii, P =.87). Strong evidence of association was found with haplotype analysis, with a positive association with one haplotype (P =.009) and a negative association with another haplotype (P =.007). Substantial linkage disequilibrium (P<.001) was detected between 4 of the 5 SNPs (SNPs 3, 9i, 9ii, and 11). CONCLUSIONS This integrated approach of genetic linkage and positional association analyses implicates tau as a susceptibility gene for idiopathic PD.
Modulation of guinea‐pig cardiac L‐type calcium current by nitric oxide synthase inhibitors

1 Electrophysiological (whole‐cell clamp) techniques were used to study the effect of NO synthase (NOS) inhibitors on guinea‐pig ventricular calcium current (ICa), and biochemical measurements (Western blot and citrulline synthesis) were made to investigate the possible mechanisms of action. 2 The two NOS inhibitors, NG‐monomethyl‐L‐arginine (L‐NMMA, 1 mM) and NG‐nitro‐L‐arginine (L‐NNA, 1 mM), induced a rapid increase in ICa when applied to the external solution. D‐NMMA (1 mM), the stereoisomer of L‐NMMA, which has no effect on NOS, did not enhance ICa. 3 Western blot experiments gave no indication of the presence of inducible NOS protein (iNOS) in our cell preparation, neither immediately after dissociation nor after more than 24 h. Statistically, there was no significant difference between electrophysiological experiments performed on freshly dissociated cells and experiments performed the next day. Moreover cells prepared and kept in the presence of dexamethasone (3 μM), to inhibit the expression of iNOS, gave the same response to L‐NMMA as control cells. 4 The stimulatory effect of L‐NMMA (1 mM) on basal ICa was reversed by competition with higher doses (5 mM) of externally applied L‐arginine, the natural substrate of NOS. The effect of L‐NMMA was also eliminated by L‐arginine in the patch pipette solution. 5 Intracellular perfusion with GDPβS (0.5 mM), which stabilizes the G‐proteins in the inactive state, did not affect the L‐NMMA‐induced stimulation of ICa. 6 Carbachol (1 μM) reduced the ICa previously stimulated by L‐NMMA, and intracellular cGMP (10 μM) prevented L‐NMMA enhancement. 7 Simultaneous treatment with L‐NMMA and isoprenaline (1 μM) induced a non‐cumulative enhancement of ICa that could not be reversed by carbachol (1 μM). 8 NO synthesis, measured by the formation of [3H]citrulline from L‐[3H]arginine during a 15 min incubation, showed a relatively high basal NO production, which was inhibited by L‐NMMA but not affected by carbachol. 9 These results suggest that inhibitors of NOS are able to modulate the basal ventricular ICa in the absence of a receptor‐mediated pathway, and that NO might be required for the muscarinic reduction of ICa under isoprenaline stimulation, even if NO production is not directly controlled by the muscarinic pathway.
Determinants of Online Reservation Acceptance: An Empirical Study

The evolvement of E-commerce has created a competitive environment that changed the way of doing business. Travel related industry such as hoteliers, airlines, and travel agencies compete effectively in the current business environment by adopting online reservation system. Despite million of dollars spent on web-technology investment, there are customers who prefer to stick to the traditional method of business transactions. These, point out the need to study the determinants of user acceptance of online reservation. Grounded in the extended Technology Acceptance Model (TAM), the current study attempts to investigate the causal link between individual differences in computer self efficacy (CSE), perceived ease of use (PEOU), perceived usefulness (PU), perceived credibility (PC), and behavioral intention (BI) in Malaysia environment. Results of Structural Equation Modeling (SEM) demonstrate that CSE has a significant relationship with PU, PU and PC have significant influence on BI, PEOU has no significant influence on BI, and CSE does not predict PC and PEOU.
Autonomic dysreflexia; a medical emergency.

Key Points • Autonomic Dysreflexia (AD) is a medical emergency that occurs due to a rapid rise in blood pressure in response to a harmful or painful stimulus below the level of your Spinal Cord Injury (SCI) • It occurs in people with SCI at T6 and above but has in rare occasions been reported in individuals with SCI as low as T8 • If left untreated your blood pressure can rise to dangerous levels, risking stroke, cardiac problems, seizures, even death • Typically there is a pounding headache as your blood pressure rises. Other symptoms can include redness and sweating above the level of your SCI, slow heart rate, goosebumps, nausea, nasal congestion, blurred vision, shortness of breath and anxiety • Some or all of the symptoms may be present • AD can be triggered by any continuous painful or irritating stimulus below the level of your lesion. The most common causes are related to the bladder or bowel • Relieving the cause of the AD will resolve your AD episode • If the cause cannot be found or treated, medication is required to lower your blood pressure which may require a visit to your nearest emergency department • All people with SCI at T6 and above should carry their Autonomic Dysreflexia Medical Emergency Card at all times • The best treatment for AD is prevention • People at risk of AD often carry an ‘AD Kit’ with them – items useful to resolve AD such as catheters and prescribed medication
The Efficacy of Nanoscale Poly[bis(trifluoroethoxy) phosphazene] (PTFEP) Coatings in Reducing Thrombogenicity and Late In-Stent Stenosis in a Porcine Coronary Artery Model

Objectives:Previous experimental studies have demonstrated that poly[bis(trifluoroethoxy)phosphazene] (PTFEP) nanocoated stents have antithrombotic characteristics, reduce in-stent stenosis, prevent wall inflammation, and do not hamper endothelialization. This study was designed to validate these findings in a porcine coronary artery model. Materials and Methods:PTFEP-coated (n = 15) and bare stents (n= 13) were implanted in coronary arteries of 18 mini-pigs (4- and 12-week follow-up). Primary study endpoints were thrombogenicity and in-stent stenosis, secondary study endpoints were inflammatory response and re-endothelialization evaluated by quantitative angiography and light microscopy. Results:No thrombus deposition occurred on any stent. At 4 weeks follow-up, the bare stents (n = 4) had a significantly smaller neointimal area (1.93 vs. 3.20 mm2, P = 0.009). At 12 weeks, PTFEP-coated stents (n = 11) had significantly superior results in almost all parameters: neointimal area (2.25 vs. 2.65 mm2, P = 0.034), neointimal height (204.46 vs. 299.41 &mgr;m, P = 0.048), percentage stenosis (38.25 vs. 50.42%, P = 0.019), and inflammation score (0.12 vs. 0.30, P = 0.029). Complete re-endothelialization was seen in both stent types at both intervals. Conclusion:At long-term follow-up, the superior results of PTFEP-coated stents were characterized by a noteworthy reduction of neointimal growth and inflammatory response.
The Use of Body Motion Analysis as an Artificial Neural Network Method for Personal Identification

There is limited evidence to suggest an optimal biometric method in order to achieve an enhanced level of information security as well as recognition accuracy. Recently, novel approaches for the development of practical biometric identification systems have shown that body motion analysis seems to overcome most of the risks and vulnerabilities related to security and privacy and also characterized by simplicity and precision. This study examined the ability of a body motion analysis system to accurately identify individuals throughout specific periods of time. Specifically, thirteen males have performed three trials throughout a single day as well as pre and post an eight-week period. A high speed video camera was used to collect recordings of a full stride (two consecutive steps). Analysis of the video data was performed using a digitizing hardware system. After video analysis, various kinematic variables related to foot motion (total time, stride rate, stride length, flying time, contact time, velocity) were compared in order to measure body motion analysis’ recognition efficiency. These kinematic variables are the inputs for a classical artificial neural network (ANN), which is used for the person’s recognition. The output is the identity of the person. The ANN’s is optimized regarding the values of crucial parameters such as the number of neurons, the time parameter and the initial value of the learning rate, etc. using the evaluation set. The evaluation criterion is the successful percentage of the person’s identification. Statistics showed that trials’ variations throughout day and the eight-week period for most kinematic variables were small, indicating high data reproducibility. The respective initial ANN results are encouraging and indicate an increased efficiency of body motion analysis on personal identification. In future, more measurement-trials per person during the reference period time and a larger participant sample may allow the results’ generalization. It is also suggested that in order to obtain fast and accurate biometric identification even after a relatively long period of time, one may prefer body motion analysis over other biometric
