To cheat or not to cheat: effects of moral perspective and situational variables on students' attitudes

One hundred and ninety‐six Israeli middle‐school students participated in a study that explored the effects of moral orientation (moral versus conventional)and of three situational variables on attitudes toward two types of cheating in school exams—copying from others (‘active’)and letting others copy (‘passive’). Several vignettes that were comprised of different combinations of the three situational variables—exam importance, supervision level and peers' norms—were used as the main instrument. It was found that a‐morally oriented students approved significantly more of cheating than morally oriented students. Importance of exam had marginally significant effects on active copying. Level of supervision during exam and classmates' norms had significant effects on both active and passive cheating attitudes.
Sign language planning: pragmatism, pessimism and principles

This article introduces the present collection of sign language planning studies. Contextualising the analyses against the backdrop of core issues in the theory of language planning and the evolution of applied sign linguistics, it is argued that – while the sociolinguistic circumstances of signed languages worldwide can, in many respects, be treated analogously to those of other minority languages – there are unique features to the socio-political landscape facing signing communities and sign language planners. With reference to topics addressed in this collection (language teaching, codification, education and legislation), the distribution of power emerges as a constant theme, inevitably centred upon the relationship between Deaf people and others. While immense changes in sign language prospects have evidently taken place worldwide over the last half-century, it can be seen that the power balance remains precarious and that major forces continue to align to ensure that sign language planning remains at best an uphill struggle.
Trinocular stereo matching with composite disparity space image

In this paper we propose a method that smartly improves occlusion handling in stereo matching using trinocular stereo. The main idea is based on the assumption that any occluded region in a matched stereo pair (middle-left images) in general is not occluded in the opposite matched pair (middle-right images). Then two disparity space images (DSI) are merged in one composite DSI. The proposed integration differs from the known approach that uses a cumulative cost. The experimental results are evaluated on the Middlebury data set, showing high performance of the proposed algorithm especially in the occluded regions. Our method solves the problem on the base of a real matching cost, in such a way a global optimization problem is solved just once, and the resultant solution does not have to be corrected in the occluded regions. In contrast, the traditional methods that use two images approach have to complicate a lot their algorithms by additional add hog or heuristic techniques to reach competitive results in occluded regions.
A Proactive Horizontal Handover Algorithm Based on RSSI Supported by a New Gradient Predictor

Two important high bandwidth wireless certifications in our days are Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Fidelity (WiFi). They can interoperate to form a wide geographical network in which Mobile Client (MC) can move. We suppose a combination of two WiFi Access Points (AP) and a WiMAX Base Station (BS) that interoperate putting a WiMAX Wireless Network Interface Card (WNIC) in the WiFi AP. The BS can request real time video or Video on Demand (VoD) from a server allocated in the fixed network (to which the BS is connected). In order to model the movement of the MC, we build a diagram state to represent the areas in which MC can stay, and from what area to which one the MC could pass. Classifying the areas in connected and disconnected ones, we can discover the different actions that are achieved by different entities of a simple protocol, that are allocated in the BS and the AP. These entities are in charge of controlling the buffers to efficiently support disconnections due to handover and out of coverage situations (disconnected states). Our algorithm is based on Received Signal Strength Indicator (RSSI) measurements. These RSSI values are used to change the state in the diagram state. But to predict the next state of MC, we use a new prediction technique that we call RSSI Gradient Predictor. We test our predictor using some synthetic proposed RSSI values for different MC movement shapes. These movements include Regular and Irregular movements. The results show a good behaviour of our algorithm.
Applying reliability theory for future wireless communication networks

Enhancing the connectivity reliability is one of the most challenging requirements for the design of future wireless communications systems. The scope of this paper is to leverage the existing tool set of reliability theory for enabling reliable communication in wireless systems. Definitions, concepts, and methods of reliability theory are applied and extended to wireless communications networks, which are modeled as a repairable system. The steady-state and transient system behaviour are considered. Two new key performance indicators (KPIs) for the reliability analysis of wireless communications systems are introduced, namely mean time to first failure (MTTFF) and interval reliability (IR), and a closed form expression is derived for the MTTFF. By evaluating an exemplary scenario, the trade-off between availability, reliability and throughput is discussed.
Using a Keyness Metric for Single and Multi Document Summarisation

In this paper we show the results of our participation in the MultiLing 2013 summarisation tasks. We participated with single-document and multi-document corpus-based summarisers for both Arabic and English languages. The summarisers used word frequency lists and log likelihood calculations to generate single and multi document summaries. The single and multi summaries generated by our systems were evaluated by Arabic and English native speaker participants and by different automatic evaluation metrics, ROUGE, AutoSummENG, MeMoG and NPowER. We compare our results to other systems that participated in the same tracks on both Arabic and English languages. Our single-document summarisers performed particularly well in the automatic evaluation with our English singledocument summariser performing better on average than the results of the other participants. Our Arabic multi-document summariser performed well in the human evaluation ranking second.
Comparison of the Functional Rating Index and the 18-Item Roland-Morris Disability Questionnaire: Responsiveness and Reliability

Study Design. Retrospective design. Objectives. To compare the responsiveness and test-retest reliability of the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire in detecting change in disability in patients with work-related low back pain. Summary of Background Data. Many low back pain-specific disability questionnaires are available, including the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire. No previous study has compared the responsiveness and reliability of these questionnaires. Methods. Files of patients who had been treated for work-related low back pain at a physical therapy clinic were reviewed, and those containing initial and follow-up Functional Rating Index and 18-item Roland-Morris Disability Questionnaires were selected. The responsiveness of both questionnaires was compared using two different methods. First, using the assumption that patients receiving treatment improve over time, various responsiveness coefficients were calculated. Second, using change in work status as an external criterion to identify improved and nonimproved patients, Spearman’s &rgr; and receiver operating characteristic curves were calculated. Reliability was estimated from the subset of patients who reported no change in their condition over this period and expressed with the intraclass correlation coefficient and the minimal detectable change. Results. One hundred and forty-three patient files were retrieved. The responsiveness coefficients for the Functional Rating Index were greater than for the 18-item Roland-Morris Disability Questionnaire. The intraclass correlation coefficient values for both questionnaires calculated from 96 patient files were similar, but the minimal detectable change for the Functional Rating Index was less than for the 18-item Roland-Morris Disability Questionnaire. Conclusion. The Functional Rating Index seems preferable to the 18-item Roland-Morris Disability Questionnaire for use in clinical trials and clinical practice.
Community Influentials' Media Dependence in Dealing with a Controversial Local Issue

,Unders tanding t h e re la t ionships between and among the media and other sources of information and influence is important for a fuller explanation of the role and impact of the mass media in a social system. ’ Media institutions, like other social processes, operate within social, economic, political and technological constraints. As McQuail has so cogently noted, “the mass media as a social institution have no monopoly over the exchange and flow of information and ideas in a society. ”2 To understand the media-society relationships, the strength, focus and directions of these relationships must be delineated. Ball-Rokeach and DeFleur have posited a model of media effects which attempts to explicate the interrelationships between and among the media and other social forces.3 The model presents the mass media as one part of a tripartite relationship including the nature of the social system at large, media roles in that social system and the
Self-reported traumatic brain injury in male young offenders: A risk factor for re-offending, poor mental health and violence?

Adolescence is a risk period for offending and for traumatic brain injury (TBI) and TBI is a risk factor for poor mental health and for offending. TBI has been largely neglected from guidance on managing the mental health needs of young offenders. We sought to determine the rate of self-reported TBI, of various severities, in a male, adolescent youth offending population. We also aimed to explore whether TBI was associated with number of convictions, violent offending, mental health problems and drug misuse. Young male offenders aged 11 to 19 years were recruited from a Young Offender Institute, a Youth Offending Team and a special needs school. A total of 197 participants were approached and 186 (94.4%) completed the study. They completed self-reports on TBI, crime history, mental health and drug use. TBI with loss of consciousness (LOC) was reported by 46% of the sample. LOC consistent with mild TBI was reported by 29.6%, and 16.6% reported LOC consistent with moderate to severe TBI. Possible TBI was reported by a further 19.1%. Repeat injury was common – with 32% reporting more than one LOC. Frequency of self-reported TBI was associated with more convictions. Three or more self-reported TBIs were associated with greater violence in offences. Those with self-reported TBI were also at risk of greater mental health problems and of misuse of cannabis. TBI may be associated with offending behaviour and worse mental health outcomes. Addressing TBI within adolescent offenders with neurorehabilitative input may be important for improving well-being and reducing re-offending.
On the role of biomedical knowledge in the acquisition of clinical knowledge

Basic science teaching in undergraduate medical education faces several challenges. One prominent discussion is focused on the relevance of biomedical knowledge to the development and integration of clinical knowledge. Although the value of basic science knowledge is generally emphasised, theoretical positions on the relative role of this knowledge and the optimal approach to its instruction differ. The present paper addresses whether and to what extent biomedical knowledge is related to the development of clinical knowledge.
Crack Growth and Lifetime of Concrete under Long Time Loading

Edge-notched eccentrically compressed fracture specimens made of aggregate of reduced size are loaded in standard creep test frames. Measurements of the time rate of crack mouth opening in notched concrete specimens subjected to constant load of almost one month duration are reported and analyzed. To reveal the size effect, geometrically similar specimens of four sizes in the ratio I :2:4:8 are tested. The results are success­ fully described by a previously proposed time-dependent generalization of the R-curve model, in which the rate of crack growth is a function of the ratio of the stress intensity factor to the R-curve, and linear aging viscoelastic creep in the bulk of the specimen is treated according to the operator method. Good predictions are also obtained with a simplified method in which the R-curve is replaced by a constant asymptotic value of the critical stress intensity factor and creep is handled in similarity to the effective modulus method, neglecting the history effect. The time curves of crack opening terminate with an infinite slope, indicating the lifetime. The finiteness of the lifetime is not caused by creep, but by time-dependent crack growth, which dominates the final stage of crack opening. The initial stage of crack opening, on the other hand, is dominated by creep. Tests are conducted both for concretes of normal strength of 33.4 MPa (4,847 psi) in compression and relatively high strength of 46.4 MPa (6,442 psi). For the stronger concrete, the lifetimes are found to be longer. An increase of specimen size is found to decrease the lifetime. Since the same type of model was previously shown capable of describing all other known time-dependent fracture phenomena in concrete, a rather general applicability may be expected.
An Interactive Genre within the University Textbook: The Preface

This article examines the communicative categories and linguistic features of university textbook prefaces. The textbook preface is a highly interactive genre, with a double purpose: informative and promotional. The analysis of the genre moves and of their realization reveals that the preface is used by the author both to help the audience use the book and to convince them of the value of the book. This twofold purpose accounts for the most relevant features of prefaces: the frequent use of textual metadiscourse and the pervasive presence of evaluation. The criteria used in the preface to evaluate the textbook are related to the audience's expectations about introductory textbooks: novelty, usefulness, accessibility, comprehensiveness, importance, and interest.
Cytochrome P-450 Inhibition Attenuates Hypertension Induced by Reductions in Uterine Perfusion Pressure in Pregnant Rats

Abstract—The present study tested the hypothesis that cytochrome P-450 (CYP) metabolites of arachidonic acid (AA) are involved in mediating hypertension and renal vasoconstriction during chronic reductions in uterine perfusion pressure (RUPP) in pregnant rats. 1-aminobenzotriazole (ABT), a CYP enzyme inhibitor (25 mg/kg per day), or vehicle (saline 0.9%) was administered for 7 days to normal pregnant (NP) rats and to pregnant rats with chronic RUPP. RUPP rats infused with vehicle showed significantly (P <0.01) higher mean arterial pressure (MAP) (130±2 versus 106±1 mm Hg), renal vascular resistance (RVR) (22.6±1.8 versus 16.3±1.1 mm Hg/mL per minute) and lower (P <0.05) glomerular filtration rate (GFR) (1.6±0.1 versus 2.3±0.1 mL/min) than NP rats. ABT decreased (P <0.01) MAP in RUPP rats (111±1 mm Hg), whereas it had no effect in NP rats (108±2 mm Hg). CYP inhibition also attenuated the differences in renal hemodynamics observed between NP and RUPP rats. After treatment with ABT, RVR and GFR were similar in RUPP rats (19.3±1.5 mm Hg/mL per minute and 2.0±0.2 mL/min, respectively) and NP rats (16.3±2.4 mm Hg/mL per minute and 2.4±0.2 mL/min). The effects of CYP enzymes inhibitor in RUPP rats were associated with a reduction (P <0.05) of 20-HETE formation (32%) and a decreased (P <0.05) expression (33%) of CYP4A protein in renal cortex. In contrast, renal epoxygenase activity did not change in these animals. These results suggest that 20-HETE contributes to hypertension and renal vasoconstriction induced by chronic RUPP in pregnant rats.
Ethnic/Racial and Gender Variations Among Meanings Given to, and Preferences for, the Natural Environment

The purpose of this study was to explore how ethnicity/race and gender, in combination, influence person-natural environment interactions. The sample consisted of 525 university students equally representing Black, Hispanic, and White ethnic/racial groups. Two research questions were developed and examined: (a) how ethnicity/race and gender are related to the affective meanings attached to the natural environment, and (b) how ethnicity/race and gender influence preference for environmental settings in outdoor recreation. The results for both research questions suggest that ethnicity/race and gender influence the affective meanings attached to a forest environment and the environmental settings preferred for outdoor recreation. Further analyses were performed across the 12 affective meaning scales on forest environments and six environmental setting preference scales. Differences in meanings and preferences across the ethnicity/race and gender attributes are presented and discussed. The final section of th.
Efficient privacy preserving video surveillance

Widespread use of surveillance cameras in offices and other business establishments, pose a significant threat to the privacy of the employees and visitors. The challenge of introducing privacy and security in such a practical surveillance system has been stifled by the enormous computational and communication overhead required by the solutions. In this paper, we propose an efficient framework to carry out privacy preserving surveillance. We split each frame into a set of random images. Each image by itself does not convey any meaningful information about the original frame, while collectively, they retain all the information. Our solution is derived from a secret sharing scheme based on the Chinese Remainder Theorem, suitably adapted to image data. Our method enables distributed secure processing and storage, while retaining the ability to reconstruct the original data in case of a legal requirement. The system installed in an office like environment can effectively detect and track people, or solve similar surveillance tasks. Our proposed paradigm is highly efficient compared to Secure Multiparty Computation, making privacy preserving surveillance, practical.
Structured Interviewing for OCB: Construct Validity, Faking, and the Effects of Question Type

This study reports the results of an effort to develop a structured interview designed to measure the propensity to engage in organizational citizenship behavior (OCB). Results indicated that participants were unable to improve their scores by attempting to fake the interview. Evidence of construct validity was provided in that we observed several meaningful relationships between scores on the interview and theoretically relevant dispositional variables such as positive affect and empathy. Additionally, regression analyses revealed that ratings obtained from the OCB interview significantly related to coworker ratings of OCB. Overall, the results of the study provide evidence that structured interviews have the potential for being a useful tool for predicting who will engage in OCB in the work environment.
Automatic Unsupervised Tensor Mining with Quality Assessment

A popular tool for unsupervised modelling and mining multi-aspect data is tensor decomposition. In an exploratory setting, where and no labels or ground truth are available how can we automatically decide how many components to extract? How can we assess the quality of our results, so that a domain expert can factor this quality measure in the interpretation of our results? In this paper, we introduce AutoTen, a novel automatic unsupervised tensor mining algorithm with minimal user intervention, which leverages and improves upon heuristics that assess the result quality. We extensively evaluate AutoTen's performance on synthetic data, outperforming existing baselines on this very hard problem. Finally, we apply AutoTen on a variety of real datasets, providing insights and discoveries. We view this work as a step towards a fully automated, unsupervised tensor mining tool that can be easily adopted by practitioners in academia and industry.
Thermal-safety margins and the necessity of thermoregulatory behavior across latitude and elevation

Significance We find that most terrestrial ectotherms are insufficiently tolerant of high temperatures to survive the warmest potential body temperatures in exposed habitats and must therefore thermoregulate by using shade, burrows, or evaporative cooling. Our results reveal that exposure to extreme heat can occur even at high elevations and latitudes and show why heat-tolerance limits are relatively invariant in comparison with cold limits. To survive climate warming, ectotherms in most areas may need to rely on behaviors—and have access to habitats—that provide a reprieve from extreme operative temperatures. Physiological thermal-tolerance limits of terrestrial ectotherms often exceed local air temperatures, implying a high degree of thermal safety (an excess of warm or cold thermal tolerance). However, air temperatures can be very different from the equilibrium body temperature of an individual ectotherm. Here, we compile thermal-tolerance limits of ectotherms across a wide range of latitudes and elevations and compare these thermal limits both to air and to operative body temperatures (theoretically equilibrated body temperatures) of small ectothermic animals during the warmest and coldest times of the year. We show that extreme operative body temperatures in exposed habitats match or exceed the physiological thermal limits of most ectotherms. Therefore, contrary to previous findings using air temperatures, most ectotherms do not have a physiological thermal-safety margin. They must therefore rely on behavior to avoid overheating during the warmest times, especially in the lowland tropics. Likewise, species living at temperate latitudes and in alpine habitats must retreat to avoid lethal cold exposure. Behavioral plasticity of habitat use and the energetic consequences of thermal retreats are therefore critical aspects of species’ vulnerability to climate warming and extreme events.
