A Qualitative Exploration of Cyber-Bystanders and Moral Engagement

Studies have found that moral disengagement plays a significant role in the continuation of bullying situations (Bonanno, 2005); however, the moral stance of cyber-bystanders — those who witness online bullying — is not yet clear. While research into traditional face-to-face bullying reported that peers would probably or certainly intervene to support victims in 43% of cases (Rigby & Johnson, 2006) actual intervention is reportedly much less (Atlas & Pepler, 1998; Craig & Pepler, 1997). Little is known, however, about the attitudes and behaviours of bystanders or witnesses when online, or their probable intentions to intervene. This study employed three digital animations of typical cyberbullying scenarios to explore young people's views of cyber-bystanders. Youth from Years 8–12 (mean age 15.06, N = 961) from one metropolitan secondary school in Adelaide, South Australia, completed an online survey after watching vignettes. To shed light on the rationale and thinking behind their understanding of bystanders and moral dis/engagement when online, this article reports on the qualitative responses from young people in relation to one of these animations/vignettes. The findings suggest that young people perceive cyber-bystanders to have the capacity to morally engage in cyberbullying incidents; however, there are various barriers to their active positive engagement. The implications can inform educators and school counsellors about possible ways to support students to intervene when they witness cyberbullying.
Participation Training, Agreement, and Teacher Participation in Decision Making

This study investigates the effects of participation training and agreement or disagreement among teachers and their principals on the teachers' desires for participation in decision making as well as their perceptions that participation would increase decision effectiveness. The results indicate that teachers who had received participation training liked participating signifi cantly more when therewas teacher-principal agreement than when there was disagreement. Conversely, teachers who had not received such training felt that participation would result in more effective decisions when there was teacher-principal disagreement than when there was agreement. Furthermore, when there was agreement, teachers who had received participation training rated the amount of desired participation and the amount of participation likely to achieve effective decisions higher than did the untrained teachers. When there was disagreement, the opposite tended to occur. Implications of the results for participation training are discussed.
Language choice, social institutions, and symbolic domination

ABSTRACT The study of language choice and code-switching can illuminate the ways in which, through language, social institutions with ethnolinguistically diverse staff and clients exercise symbolic domination. Using the example of French-language minority education in Ontario (Canada), this article examines the ways in which ethnic and institutional relations of power overlap or crosscut, forming constraints which have paradoxical effects. In an analysis of two classrooms, it is shown how an ideology of institutional monolingualism is supported or undermined by program structure, curriculum content, and the social organization of turn-taking, and how individuals use language choices and code-switching to collaborate with or resist these arrangements. The effect of these processes is to contain paradoxes and to produce new relations of power within the school.

Induced Mutant Mice Expressing Lipoprotein Lipase Exclusively in Muscle Have Subnormal Triglycerides yet Reduced High Density Lipoprotein Cholesterol Levels in Plasma*

To determine the contribution of muscle lipoprotein lipase (LPL) to lipoprotein metabolism, induced mutant mice were generated that express human LPL exclusively in muscle. By cross-breeding heterozygous LPL knockout mice with transgenic mice expressing human LPL only in muscle, animals were obtained that express human LPL primarily in skeletal muscle on either the null (L0-MCK) or normal (L2-MCK) LPL backgrounds, and these were compared with control littermates (L2). Fed and fasted post-heparin plasma (PHP) LPL activities were increased 1.4- and 2.3-fold, respectively, in L2-MCK mice and were normal in L0-MCK mice compared with controls. The specific enzyme activities of human LPL in mouse plasma was comparable to human LPL in human PHP. Skeletal muscle LPL activity was increased in both L2-MCK and L0-MCK mice in the fed (6.6-fold) and fasted (4.2-fold in L2-MCK; and 3.4-fold in L0-MCK) states. Adipose tissue LPL mRNA and activity were not detectable in L0-MCK mice. Growth and body mass composition were similar among all groups. In the fasted and fed state, L2-MCK mice had 31% and 53% reductions, respectively, in plasma triglycerides (TG), compatible with increased PHP LPL activity. Unexpectedly, both in the fasted and fed state the L0-MCK mice also had reduced TG (22%), despite normal PHP LPL activities. Very low density lipoprotein (VLDL) turnover studies revealed that the decreased TG were due to increased particle fractional catabolic rate in both L2-MCK and L0-MCK mice. Despite reduced TG, both L2-MCK and L0-MCK mice showed reduced high density lipoprotein (HDL) cholesterol levels (16% and 19%, respectively). HDL turnover studies indicated increased HDL cholesteryl ester fractional catabolic rate in the L2-MCK and L0-MCK compared with control mice. In summary, these studies suggest that muscle LPL is particularly potent with regard to VLDL metabolism and is sufficient to compensate for the lack of LPL in other tissues with regard to lipolyzing VLDL particles. With regard to HDL, muscle LPL expression does not result in normal levels due to enhanced breakdown either by mediating accelerated HDL clearance or by failing to establish normal HDL particles that are then cleared more quickly than normal. These studies provide new insights on the tissue-specific effects of LPL on lipoprotein metabolism.
Clinical Features of Immediate Hypersensitivity to Isopropylantipyrine

Hypersensitivities induced by isopropylantipyrine (IPA), a pyrazolone derivative within the wider family of non-steroidal anti-inflammatory drugs (NSAIDs), are rarely reported. We characterized the clinical features of 12 patients with IPA-induced hypersensitivity. Twelve patients with immediate hypersensitivity to IPA were enrolled and classified into two groups: group I, consisting of eight patients (66.7%) with selective hypersensitivity; and group II, consisting of four patients (33.3%) showing cross-intolerance to other NSAIDs. Skin prick and intradermal and oral provocation tests with IPA were performed. To confirm selective hypersensitivity, an aspirin oral provocation test was also conducted. The most common manifestations were cutaneous reactions (91.7%), followed by anaphylaxis (66.7%), respiratory (41.7%), ocular (16.7%), and gastrointestinal reactions (16.7%). The median age and the median age at onset were 34.5 (range, 23-55) years and 28.0 (range, 7-47) years, respectively. In both groups I and II, all patients showed negative responses to skin prick testing, whereas only two patients in group I were positive in response to intradermal IPA tests. The response time after drug exposure was shorter in group I than in group II. Here, we report on two types of IPA hypersensitivity: selective and cross-intolerant NSAID hypersensitivity. An immediate IgE-mediated reaction may be involved in patients with selective hypersensitivity, whereas a cyclooxygenase-1-related inhibition mechanism may be a responsible mechanism for the patients with cross-intolerance to multiple NSAIDs.
Exploring Levels of Moral Development Among Sex Offenders Participating in Community-Based Treatment

ABSTRACT Objective: The purpose of the present study was to investigate levels of moral reasoning among sex offenders court-ordered into a community-based treatment program. Method: The study employed a static-group comparison design in examining the moral reasoning level of 72 adult men, 32% African-American, court-ordered into a community-based treatment program for sexual offenses. Results: Comparison of the study sample to national normative data indicated that this sample of sex offenders was employing a level of moral reasoning two standard deviations lower than adults in general. Conclusion: Potential implications of the findings for enhancing community-based treatment for sex offenders were explored and discussed.
An Observational Method of Assessing Handedness in Children and Adults

The current study was performed to assess the WatHand Cabinet Test (WHCT), a newly developed multidimensional observational test of handedness. Because the test is observational, it is ideal for assessing children, as it does not require a high degree of verbal comprehension on the part of the participants. 548 individuals participated in the present study on a voluntary basis. Individuals of varying ages were examined (including 3 to 5, 6, 7, 8, 9, 10, and 11-year-olds, and 19-to 24-year-olds). Each participant was asked to complete the WHCT, the Annett Pegboard (Annett, 1985), and the Waterloo Handedness Questionnaire (WHQ) (M.P. Bryden, 1977). Overall, the total score on the WHCT was significantly correlated with both the WHQ, r =. 795, p < . 01, and the Annett Pegboard, r = . 542, p < . 01. Sub-scores measuring skilled performance, bimanual performance, and internal consistency were also examined, as well as performance on the three tests as a function of age. Overall, findings indicate that that the WHCT is a valid test of hand preference in both children and adults. Its ease of use, quick administration, and built-in quantitative sub-scores offer a robust alternative method for measuring hand preference.
Feasible Point Pursuit and Successive Approximation of Non-Convex QCQPs

Quadratically constrained quadratic programs (QCQPs) have a wide range of applications in signal processing and wireless communications. Non-convex QCQPs are NP-hard in general. Existing approaches relax the non-convexity using semi-definite relaxation (SDR) or linearize the non-convex part and solve the resulting convex problem. However, these techniques are seldom successful in even obtaining a feasible solution when the QCQP matrices are indefinite. In this letter, a new feasible point pursuit successive convex approximation (FPP-SCA) algorithm is proposed for non-convex QCQPs. FPP-SCA linearizes the non-convex parts of the problem as conventional SCA does, but adds slack variables to sustain feasibility, and a penalty to ensure slacks are sparingly used. When FPP-SCA is successful in identifying a feasible point of the non-convex QCQP, convergence to a Karush-Kuhn-Tucker (KKT) point is thereafter ensured. Simulations show the effectiveness of our proposed algorithm in obtaining feasible and near-optimal solutions, significantly outperforming existing approaches.
A Mobile Phone-Embedded Real-Time Remote Video Surveillance System With Network Camera Using Arm P

Monitoring facilities will be necessary and useful for our daily life, because it is very important for us to think about our security. This work developed an remote video surveillance system, which is organized with an integrated web server, network cameras, remote control devices and clients which connected to internet. Some kinds of devices can be used as our clients , for example, high-performance mobile phones, which are equipped with web-browsing facility or mobile phones with Wi-Fi connectivity. An specific server is located in the center of our surveillance system, which is called integrated server. It can obtain video from network cameras and then compress that video. They can accumulated as MPEG video temporally into the internal buffer of the server, and stored into a video database. It can also receive some types of requests from clients, analyze them and perform several kinds of services such as monitoring, controlling and so on. Almost all software of the surveillance system is written in C programming language. With enhanced facilities for mobile phone, our system has been available for many applications. These entire work had done on ARM11 processor with linux operating system
Contextualising the crowd in contemporary social science

This paper situates contemporary social scientific studies of crowd events and crowd behaviour in their historical and ideological context. The original ‘crowd science’ developed from definitions of ‘social problems’ that emerged in the late nineteenth century – in particular the concerns among the French establishment about the threat of the ‘mass’ to ‘civilization’. This, and the surrounding intellectual context, encouraged the development of theoretical models of the crowd characterized by forms of reductionism and irrationalism. Early accounts of ‘mass panic’ similarly suggested that collective behaviour was irrational because it was governed by primitive bio-psychological processes. After describing these early approaches to the crowd, the paper outlines how changes in late twentieth society, whereby those writing about the crowd were no longer necessarily ‘outside’ crowd events, have coincided with the development of accounts of the crowd which draw upon contemporary social scientific concepts (such as social norms, social identities, and cognition) and which assume that crowds are not alien to meaningful social and political participation, but integral to it.
Multi-layer precoding for full-dimensional massive MIMO systems

Full-dimensional massive multiple-input multiple-output (MIMO) systems boost sum spectral efficiency by offering orders of magnitude increase in multiplexing gains. In time division duplexing systems, however, the reuse of the uplink training pilots among cells results in channel estimation errors, which lead to downlink inter-cell interference, especially for cell-edge users, even with large numbers of antennas. Handling this interference with conventional network MIMO techniques is challenging due to the high channel dimensionality. Further, large antenna precoding and combining implementation is associated with high hardware complexity. In this paper, we propose multi-layer precoding to enable efficient and low complexity full-dimensional MIMO operation. Multi-layer precoding (i) leverages the directional characteristics of large-scale MIMO channels to manage inter-cell interference with low channel requirements, and (ii) allows for an efficient implementation using low-complexity hybrid analog/digital architectures. We present and evaluate a specific multi-layer precoding design for full-dimensional MIMO systems. Simulation results show the potential gains of multi-layer precoding compared with traditional pilot-contaminated massive MIMO setups despite the low channel knowledge requirements and the low-complexity implementation.
Effective protein model structure refinement by loop modeling and overall relaxation

Protein structures predicted by state‐of‐the‐art template‐based methods may still have errors when the template proteins are not similar enough to the target protein. Overall target structure may deviate from the template structures owing to differences in sequences. Structural information for some local regions such as loops may not be available when there are sequence insertions or deletions. Those structural aspects that originate from deviations from templates can be dealt with by ab initio structure refinement methods to further improve model accuracy. In the CASP11 refinement experiment, we tested three different refinement methods that utilize overall structure relaxation, loop modeling, and quality assessment of multiple initial structures. From this experiment, we conclude that the overall relaxation method can consistently improve model quality. Loop modeling is the most useful when the initial model structure is high quality, with GDT‐HA >60. The method that used multiple initial structures further refined the already refined models; the minor improvements with this method raise the issue of problem with the current energy function. Future research directions are also discussed. Proteins 2016; 84(Suppl 1):293–301. © 2015 Wiley Periodicals, Inc.
Perspectives on cross-national comparisons of social work

In this paper various attempts of studying and comparing social work in different countries are discussed and evaluated. Three main ways of making comparisons are identified: comparisons based on models of social policy, profession-oriented comparisons, and practice-oriented comparisons. Each of the three approaches captures essential aspects of similarities and differences in social work, but they all have obvious limitations as well.
Self-administered Questions and Interviewer–Respondent Familiarity

We examine the effects of interviewer–respondent familiarity on both response patterns and rates of item nonresponse when self-administered questions (SAQs) are used. We use SAQ data from a survey in which the researchers experimentally ensured that there would be varying degrees of familiarity between interviewers and respondents. Our results reveal only minimal differences in response patterns by degree of prior acquaintance between interviewer and respondent, indicating that SAQs are effective at eliminating potential bias stemming from such relationships. Our results for item nonresponse depend on how we measure the relationship between interviewer and respondent; but in all cases, it is clear that prior knowledge of one another, far from harmful, leads to low nonresponse rates to SAQs. Thus, researchers using SAQs may not need to adhere to the norm that interviewers and respondents must be strangers, with practical and cost-effective consequences for data collection.
A Hybrid Swarm Intelligence Based Particle Bee Algorithm for Benchmark Functions and Construction Site Layout Optimization

The construction site layout (CSL) design presents a particularly interesting area of study because of its relatively high level of attention to usability qualities, in addition to common engineering objectives such as cost and performance. However, it is difficult combinatorial optimization problem for engineers. Swarm intelligence (SI) was very popular and widely used in many complex optimization problems which was collective behavior of social systems such as honey bees (bee algorithm, BA) and birds (particle swarm optimization, PSO). In order to integrate BA global search ability with the local search advantages of PSO, this study proposes a new optimization hybrid swarm algorithm – the particle bee algorithm (PBA) which imitates the intelligent swarming behavior of honeybees and birds. This study compares the performance of PBA with that of genetic algorithm (GA), differential evolution (DE), bee algorithm (BA) and particle swarm optimization (PSO) for multi-dimensional benchmark numerical problems. Besides, this study compares the performance of PBA with that of BA and PSO for practical construction engineering of CSL problem. The results show that the performance of PBA is comparable to those of the mentioned algorithms in the benchmark functions and can be efficiently employed to solve a hypothetical CSL problem with high dimensionality.
This is Literacy! Reading of photographs in research on San students’ literacy in a Remote Dweller School in Botswana

I discuss here part of my larger study which investigated what San students and their non-San friends in a Remote Area Dweller (RAD) Junior Secondary School in Botswana understand as literacy in school and at home. A narrative case study approach was used to gain an in-depth understanding of what students’ value and understand by literacy. Findings across participants’ stories revealed that they saw literacy as those things that had value to them and these influenced how they read ‘the word’ and ‘the world’. Storytelling, games, singing, knowledge of different plants, basket weaving and sculpting were variously identified as literacy by the six San and Tswana participants.
A Comparative Study of Image Compression Algorithms

Digital images in their uncompressed form require an enormous amount of storage capacity. Such uncompressed data needs large transmission bandwidth for the transmission over the network. Discrete Cosine Transform (DCT) is one of the widely used image compression method and the Discrete Wavelet Transform (DWT) provides substantial improvements in the quality of picture because of multi resolution nature. Image compression reduces the storage space of image and also maintains the quality information of the image. In this research study the performance of three most widely used techniques namely DCT, DWT and Hybrid DCT-DWT are discussed for image compression and their performance is evaluated in terms of Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and Compression Ratio (CR). The experimental results obtained from the study shows that the Hybrid DCT- DWT technique for image compression has in general a better performance than individual DCT or DWT.
Speaking of Complexity in Management Theory and Practice

This paper describes a complexity perspective on organizational life by drawing on three distinctive sources. First, we describe the way different natural scientists talk of their work in simulating complex dynamical systems. Second, we listen to the contribution of social scientists in describing the dynamics of human interaction and third, we describe group analytic practice as it illuminates the emotional, prelinguistic processes at work in the group matrix. We argue that together these insights allow us to speak of the nature of self-organization in human systems in a way that emphasizes inter subjectivity, emergence and de-centred agency in contrast to the dominant voice in much management thinking which emphasizes objectivity, control and individual agency. We then relate how the complexity perspective we describe informs our approach to organizational consulting in which we participate in networks of self-organizing everyday conversation whereby the patterned structure of organizational activity is paradoxically both sustained and changed.
PV Penetration Limits in Low Voltage Networks and Voltage Variations

Photovoltaic embedded generation in low-voltage ac networks is quite popular; however, despite its benefits, there are some problems especially when photovoltaic (PV) penetration exceeds certain thresholds. Among others, voltage violation is of prime importance. Our review of the literature focused on PV penetration limits due to voltage violations in low-voltage (LV) networks. The review revealed that voltage violations can occur at a penetration level as low as 2.5% when a large distributed generator (DG) is installed at a single point. Alternatively, a LV network can host a large number of photovoltaic distributed generators (PVDGs), with a penetration level up to 110% if evenly distributed over shorter lengths. However, an LV network has no rules of thumb for safe penetration limits. Penetration-level calculations have been found that they used numerous approaches, which we have analyzed and discussed to adopt a more rational and unified approach. Our literature review revealed that, in LVs, a very high penetration level can be achieved as compared with medium-voltage (MV) networks. However, MV voltage-level control problems impose a limit for PV hosting in LV networks. There is a need to evolve strategies for robust voltage control at the MV level and to develop certain rules of thumb for PV penetration limits in LV networks independent of the MV level, to increase the PV hosting capacity.
