Influence of Behavior Perceptions and Gender on Teachers' Judgments of Students' Academic Skill.

This study evaluated the hypothesis that gender and behavior, as perceived by teachers, affect judgments of the academic skills of their students. A path model was proposed to describe the relationships among tested academic skill, gender, behavior grades, and teachers' academic judgments. The model was evaluated separately in each of 3 grades (kindergaten-2nd) in 2 locations, with scholastic grades and structured ratings in specific academic skill areas as the dependent variables. Results showed that, after tested academic skill and gender were controlled for, teachers' perceptions of students' behavior constituted a significant component of their scholastic judgments
Detecting Manipulated Remote Call Streams

In the Internet, mobile code is ubiquitous and includes such examples as browser plug-ins, Java applets, and document m this paper, we address an important vulnerability in mobile code security that exists in remote execution systems such as Globus, and SETI@Home. These systems schedule user jobs for execution on remote idle machines. However, they sen their important system calls back to the local machine for execution. Hence, an evil process on the remote machine can ma a user’s job to send destructive system calls back to the local machine. We have developed techniques to remotely de manipulation. Before the job is submitted for remote execution, we construct a model of the user’s binary program using static analys binary analysis is applicable to commodity remote execution systems and applications. During remote job execution, the checks all system calls arriving at the local machine. Execution is only allowed to continue while the model remains valid. W with a finite-state machine model that accepts sequences of system calls and then build optimizations into the model to im precision and efficiency. We also propose two program transformations, renaming and null call insertion, that have a sig impact on the precision and efficiency. As a desirable side-effect, these techniques also obfuscate the program, thus making for the adversary to reverse engineer the code. We have implemented a simulated remote execution environment to demon optimizations and transformations of the binary program increase the precision and efficiency. In our test programs, unop models increase run-time by 0.5% or less. At moderate levels of optimization, run-time increases by less than 13% with p gains reaching 74%.
Development and validation of perceived rehabilitation require questionnaires for caregivers of people with schizophrenia

Abstract Objective. This study aimed at developing and validating the Perceived Rehabilitation Needs Questionnaires for Caregivers (PRNQ-Cs) of people with schizophrenia. Methods. The items of PRNQ-C were generated based on focus group discussion and literature review. A validation study was conducted to examine its psychometric properties among 98 caregivers who were recruited via convenience sampling. Results. Through the use of direct oblique rotation, exploratory factor analysis yielded an eight-factor solution which accounted for 64.39% of the total variance. Its internal consistency and test–retest reliability were satisfactory. Conclusion. Through cross-cultural validation, the PRNQ-C is applicable in other Chinese communities with huge population of schizophrenia.
The Effect of Ascorbic Acid on the Pharmacokinetics of Levodopa in Elderly Patients with Parkinson Disease

Levodopa (LD) is one of the most effective drugs for clinical symptoms in patients with Parkinson disease (PD). Most PD patients are advanced in age and may have trouble with LD absorption because aging influences drug absorption processes. Previous reports have indicated that ascorbic acid (AsA) can reduce LD dosage without losing its effectiveness. The current study sought to determine whether AsA affects LD absorption in elderly PD patients. Sixty-seven elderly PD patients took a tablet orally containing 100 mg LD and 10 mg carbidopa following an overnight fast. Plasma LD concentrations were determined at 6 points up to 3 hours, using high-performance liquid chromatography with electrochemical detection. The area under the curve (AUC), peak drug concentration (Cmax), and time to peak drug concentration (Tmax) were calculated. The pharmacokinetic evaluation was repeatedly performed 1 week later in the same way except for adding 200 mg AsA to the tablet. The changes in AUC, Cmax, and Tmax between the tests were evaluated. Significant changes in these parameters were not observed when analyzed using data from all patients. However, significant increases in AUC and Cmax, and a significant reduction in Tmax by adding AsA were observed in 25 patients with baseline AUC ≤2500 ng·hour/mL. In conclusion, AsA can improve LD absorption in elderly PD patients with poor LD bioavailability. LD therapy in combination with AsA may be one of the strategies for PD treatment.
Team Climate, Emotional Labor and Burnout of Physicians: A Multilevel Model

Objectives: This study applied a multilevel analysis to verify the relationships among team climate, emotional labor, and physician burnout. Methods: We conducted a questionnaire survey for the physicians in Taiwanese hospitals. A total number of 530 physicians from 30 physician teams participated in this study. Hierarchical linear modeling (HLM) was used to test the multilevel hypotheses. Results: (1) deep acting of emotional labor was significantly associated with three components of burnout, while surface acting was only significantly associated with emotional exhaustion; (2) highly significant association between team climate and burnout for three components (emotional exhaustion, γ_(01) = -. 651, p ＜ . 001; depersonalization, γ_(01) = -. 491, p ＜ . 01; reduced personal accomplishment, γ_(01) = -. 795, p ＜ . 001); and (3) team climate only has a significant moderating effect on the relationship between surface acting of emotional labor and emotional exhaustion (γ_(11) = -. 446, p ＜ . 05). Conclusions: The results support the hypothesis that team climate and emotional labor have impacts on physician burnout. The findings remind hospital executives that climate of physician team help to mitigate physician burnout. In addition, the findings could help to clarify some aspects of the emotional dimensions of physicians with a view to improving the quality of service.
Effectiveness of audiovisual distraction in behavior modification during dental caries assessment and sealant placement in children with autism spectrum disorder

Background: The aim of this study was to evaluate the effectiveness of audiovisual (AV) distraction in behavior modification during dental caries assessment and sealant placement in children with autism spectrum disorder. Materials and Methods: This study was conducted on 28 children diagnosed with autism spectrum disorder, aged 6.5−9.8 years. Children underwent one introductory (desensitization) appointment and three treatment sessions. During the introductory session, children had the procedures explained to them, they watched a movie projected on a screen while oral screening and assessment of cooperation level were carried out. In treatment session I, oral examination, charting, and dental x-rays were undertaken, whereas the children watched movies with or without video eyewear. During treatment sessions II/III, dental prophylaxis was carried out on upper and lower jaws in addition to the application of dental sealants on the right upper and lower and the left upper and lower permanent molars, respectively, while the children were distracted by cartoon movies using video eyewear. Changes in pulse oximeter and heart rate were recorded every 5 min. Independent samples t-test was used to assess the significance of changes in pulse and O2 saturation levels during each visit. Results: International Caries Detection and Assessment System-code 2 was found to be the most prevalent (n = 58; 52%). A significant difference (P < 0.02) was observed in mean heart rate during dental screening of the upper and lower jaws with and without video eyewear. A decrease was observed in the mean heart rate during subsequent treatment sessions. Conclusion: Initial desensitization appointment and “tell-show-do” approach, followed by short and positive treatment sessions, assisted in gaining cooperation and improving behavior in the subjects. Video eyewear distraction proved an effective tool in managing children with autism spectrum disorder during noninvasive preventive dental procedures.
Rituximab in chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is the most common adult leukemia but is currently incurable by conventional therapeutic interventions. Rituximab has proven efficacy and tolerability in non-Hodgkin's lymphoma, achieving response rates of 73% and 48% in previously untreated or relapsed/refractory indolent non-Hodgkin's lymphoma, respectively. However, the standard dose and schedule (375 mg/m2 once-weekly for 4 weeks) may not be optimal for patients with previously treated small lymphocytic lymphoma, the lymphomatous equivalent of CLL. Nevertheless, good response rates have been achieved in untreated CLL and small lymphocytic lymphoma using the standard dose and schedule and also using higher or more frequent dosing, indicating that rituximab is an active agent in this setting. More recently, the combination of rituximab and fludarabine or fludarabine-containing regimens has yielded overall response rates of 95%, with complete response rates up to 66% in previously untreated CLL. These response rates are among the highest achieved by any regimen in CLL. These studies indicate that immunochemotherapy with rituximab may offer improved outcomes for patients with CLL.

Efficient stream compaction on wide SIMD many-core architectures

Stream compaction is a common parallel primitive used to remove unwanted elements in sparse data. This allows highly parallel algorithms to maintain performance over several processing steps and reduces overall memory usage. For wide SIMD many-core architectures, we present a novel stream compaction algorithm and explore several variations thereof. Our algorithm is designed to maximize concurrent execution, with minimal use of synchronization. Bandwidth and auxiliary storage requirements are reduced significantly, which allows for substantially better performance. We have tested our algorithms using CUDA on a PC with an NVIDIA GeForce GTX280 GPU. On this hardware, our reference implementation provides a 3x speedup over previous published algorithms.
Investigation of Pre-Service Science Teachers' Academic Self-Efficacy and Academic Motivation toward Biology

The purpose of this research was to examine pre-service science teachers’ academic motivation and academic self-efficacy toward biology. The sample consisted of 369 pre-service science teachers who enrolled in the faculty of education of two universities in Turkey. Data were collected through Academic Motivation Scale (AMS) (Glynn & Koballa, 2006) and Academic Self-efficacy Scale (ASES) (Woo, 1999). The findings revealed that pre-service science teachers’ academic self-efficacy and academic motivation toward biology are high. Additionally, combination of the independent variables was significantly related to the academic self-efficacy scores, while it was not significantly related to the academic motivation. More specifically, it was found that only university variable made a statistically significant contribution to the prediction of pre-service science teachers’ academic motivation and academic self-efficacy. There were strong, positive correlations between pre-service science teachers’ academic motivation and academic self-efficacy and subdimensions of AMS and ASES except ‘test anxiety’. The relationship of test anxiety with all of the subdimensions was small.
Statistical Analysis of Chroma Features in Western Music Predicts Human Judgments of Tonality

Abstract Motivated by evidence that image source statistics predict the response properties of several visual perception aspects, we provide an empirical analysis of the relation between chroma statistics and human judgments of tonality. To accomplish this, a statistical analysis method based on chroma feature covariance is proposed. It makes use of a large collection of western music to build a tonal profile. The obtained profile is compared to alternative tonal profiles proposed in the literature, either cognitively, perceptually, or theoretically inspired. The high degree of correlation we find between the covariance-based tonal profile proposed here and several ones proposed in the literature (reaching values higher than 0.9) is interpreted as evidence that human-derived profiles faithfully reflect the statistics of the musical input listeners have been exposed to. Furthermore, we show that very short time scales allow us to correctly predict these profiles, which brings us to discuss the role that local-scale implicit learning plays in building mental representations of tonality.
Anxiety Response to Psychological Feedback among Psychiatric Inpatients

This study investigated determinants of state-anxiety responses to an ego-threatening event for 79 psychiatric inpatients. Specifically, state-anxiety levels were assessed in high and low trait-anxious internal and external patients immediately prior to the presentation of individualized psychological test feedback. Analysis of variance demonstrated that high trait-anxious patients reported higher levels of state anxiety than low trait-anxious patients. Further, external patients reported significantly higher levels of state anxiety than internal patients. Multiple regression indicated that locus of control and trait anxiety each uniquely contributed to the distribution of state-anxiety scores. Findings were discussed in terms of established correlates of locus of control orientation and in relation to social learning theory and the state-trait anxiety distinction.
Limitations of Applicative Bisimulation (Preliminary Report)

We present a series of examples that illuminate an important aspect of the semantics of higher-order functions with local state. Namely that certain behaviour of such functions can only be observed by pro- viding them with arguments that contain the functions themselves. This provides evidence for the necessity of complex conditions for functions in modern semantics for state, such as logical relations and Kripke-like bisimulations, where related functions are applied to related arguments (that may contain the functions). It also suggests that simpler semantics, such as those based on applicative bisimulations where functions are ap- plied to identical arguments, would not scale to higher-order languages with local state.
Collective Dynamic Choice: The Necessity of Time Inconsistency

We study collective decisions by time-discounting individuals choosing a common consumption stream. We show that with any heterogeneity in time preferences, every Pareto efficient and non-dictatorial method of aggregating utility functions must be time-inconsistent. We also show that decisions made via non-dictatorial voting methods are intransitive.
Association Rule Generation for Student Performance Analysis usingApriori Algorithm

—The objective of the educational institution that is producing good results in their academic exams can be achieved by using the data mining techniques which can be applied to predict the performance of the students and to impart the quality of education in the educational institutions. Data mining is used to extract meaningful information and to develop relationships among variables stored in large data set. In this paper, Apriori algorithm is used which extracts the set of rules, specific to each class and analyzes the given data to classify the student based on their performance in academics. Students are classified based on their involvement in doing assignment, internal assessment tests, attendance etc., which helps to predict the performance of the student based on the pattern extracted from the educational database. This would help to identify the average and below average students and to improve their performance to provide good results. This analysis further helps matching organization " s requirement with students profile to provide placement for the students. Also, the interestingness of a rule is measured using lift in itself and as a part in formulae. The range of values that lift may take is used to normalize lift so that it is more effective as a measure of interestingness. This standardization is extended to account for minimum support and confidence thresholds.
Error analysis of localization systems for sensor networks

The establishment of a localization system is an important task in wireless sensor networks. Due to the geographic correlation of the sensed data, location information is commonly used to name the gathered data, address nodes and regions, and also improve the performance of many geographic algorithms. Depending on the localization algorithm, different error behaviors (e.g., mean, probability distribution, and correlation) can be exhibited by the sensor network. The process of understanding and analysing this behavior is the first step toward a mathematical model of the localization error. Furthermore, this knowledge can also be used to propose improvements to these systems. In this work, we divide the localization systems into three components: distance estimation, position computation, and the localization algorithm. We show how each component can affect on the final error of the system. In this work, we concentrate on the third component: the localization algorithm. The error behaviors of three known localization algorithms are evaluated together in similar scenarios so the different behaviors of the localization error can be identified and analysed. The influence of these errors in geographic algorithms is also analysed, showing the importance of understanding the error behavior and the importance of geographic algorithms which consider the inaccuracy of position estimations.
The onset and offset of psychosis – and what happens in between

As one would expect for a heterogeneous syndrome like schizophrenia, at the individual level the course of symptoms and disability vary widely. Mindful that the definition of recovery/remission varies widely between studies, a recent systematic review and meta-analysis reported that the proportion of those with schizophrenia who recover on both symptom and functional outcome is modest (approximately 14%). A 10-year follow-up of the English multicentre AESOP incidence study provides more ‘fine-grained’ insights into the time course of symptom fluctuation for schizophrenia and other psychotic disorders. We highlight selected findings from the new study and speculate on the role of different outcome domains for future study (e.g. symptom, occupational/functional, cognition, physical health, patient-nominated outcomes). Because recovery is a multifaceted process, we need to develop a panel of practical and operationalizable criteria for remission and recovery.
Sofrimento psíquico e trabalho intelectual

This study aims to understand if intellectual work provides conditions for the emergence of psychic suffering in university teachers in a public institution of higher education. Use is made of the philosophical assumptions of historical materialism, work as a category of nuclear analysis of human phenomena, and also the categories of alienated labor and intellectual work. It also refers to mental illnesses as a social production. The research subjects were teachers with contracts of employment in exclusive dedication (RDIDP). It is used as an instrument for data collection, a questionnaire with closed and opened questions of opinative character. Responses were categorized and analyzed qualitatively and had not intention of giving statistical data. However, in order to better display, the same percentage of the sample are presented, among which one third (29.6%) have some health problem after entering university. Of those, 15,5% are related to the organization of work, 5,6% to the working conditions, 2,8% concomitantly to the conditions and the organization of work. The results indicate that the organization of work in a public university has shown itself as a space of psychic suffering, but also of alienation.
Statistics of the Ricean K-Factor at 5.2 Ghz in an Urban Macro-Cell Scenario

In this paper we analyze 5.2 GHz channel measurement data in an urban macro-cell scenario in order to figure out the likelihood of a free line-of-sight and the statistics of the Ricean K-factor. We introduce a physical method to obtain this information from the Doppler delay spectrum taking GPS information into account. It is found, that for short distances the direct signal is available in 62% of all cases. However, the likelihood reduces at larger distances. In addition the average K-factor reduces with increasing distance. Measured distributions are fitted and parameters are provided for use in channel modelling
Relationships among bone mineral densities, static alignment and dynamic load in patients with medial compartment knee osteoarthritis.

OBJECTIVE To investigate the relationships among bone mineral density (BMD), static alignment and the adduction moment of the knee in patients with tibiofemoral osteoarthritis (OA). METHODS Sixty-nine patients with medial compartment knee OA underwent radiographic evaluation, gait analysis and BMD measurements at the proximal tibia and lumbar spine. RESULTS The bone mineral distribution of the medial to lateral part of the proximal tibia correlated significantly with the peak knee adduction moment and the mechanical axis. Furthermore, the adduction moment correlated significantly with the mechanical axis. However, the BMD of the lumbar spine and the bone mineral distribution of the posterior to anterior part of the proximal tibia did not correlate with any other measurement. CONCLUSIONS Our results suggest that the bone mineral distribution of the proximal tibia is directly affected but lumbar BMD is not influenced by the local mechanical stress around the knee with medial compartment OA.
