Adding Color to Conflict: Disruptive Students’ Drawings of Themselves with Their Teachers

Building on work examining teachers’ perceptions of the student-teacher relationship, this study investigated how young students draw themselves with their teachers. Fourteen kindergarten and first-grade teachers each nominated 2 disruptive and 2 well-behaved students. Students then completed 1 drawing of themselves with their classroom teacher and 1 with a support teacher (e.g., librarian, art teacher) at 2 time points: the end of the school year (Phase 1) and the beginning of the next year (Phase 2). In coding for 8 markers of relationship quality—vitality/creativity, pride/happiness, vulnerability, emotional distance, tension/anger, role reversal, bizarreness/dissociation, and global pathology—we found no differences in the way that disruptive and well-behaved students depicted their own relationships with teachers. Gender and phase effects were identified, however, with boys depicting greater relational negativity than girls and all students portraying greater emotional distance at the beginning of the school year.
A qualitative study of the determinants of self-managing team effectiveness in a scrum team

There are many evidences in the literature that the use self-managing teams has positive impacts on several dimensions of team effectiveness. Agile methods, supported by the Agile Manifesto, defend the use of self-managing teams in software development in substitution of hierarchically managed, traditional teams. The goal of this research was to study how a self-managing software team works in practice and how the behaviors of the software organization support or hinder the effectiveness of such teams. We performed a single case holistic case study, looking in depth into the actual behavior of a mature Scrum team in industry. Using interviews and participant observation, we collected qualitative data from five team members in several interactions. We extract the behavior of the team and of the software company in terms of the determinants of self-managing team effectiveness defined in a theoretical model from the literature. We found evidence that 17 out of 24 determinants of this model exist in the studied context. We concluded that certain determinants can support or facilitate the adoption of methodologies like Scrum, while the use of Scrum may affect other determinants.
Satellite Cells Contribution to Exercise Mediated Muscle Hypertrophy and Repair

Satellite cells (SCs) are the most abundant skeletal muscle stem cells. They are widely recognized for their contributions to maintenance of muscle mass, regeneration and hypertrophy during the human life span. These cells are good candidates for cell therapy due to their self-renewal capabilities and presence in an undifferentiated form. Presently, a significant gap exists between our knowledge of SCs behavior and their application as a means for human skeletal muscle tissue repair and regeneration. Both physiological and pathological stimuli potentially affect SCs activation, proliferation, and terminal differentiation the former category being the focus of this article. Activation of SCs occurs following exercise, post-training micro-injuries, and electrical stimulation. Exercise, as a potent and natural stimulus, is at the center of numerous studies on SC activation and relevant fields. According to research, different exercise modalities end with various effects. This review article attempts to picture the state of the art of the SCs life span and their engagement in muscle regeneration and hypertrophy in exercise.
From IT Satisfaction to Job Satisfaction: Understanding the Role of User-Technology Fit

Information technologies (IT) are increasingly prevalent in modern organizations. Given the important role of employee users in the IT implementation process, recent studies have acknowledged employee users’ satisfaction with the implemented IT (IT satisfaction) as a salient aspect of job performance. This study extends prior literature by evaluating employees’ job satisfaction as a surrogate of job performance induced by IT utilization. Drawing on IT performance literature, we develop a research model to examine the relationship between employee users’ satisfaction with information and communication technologies (ICTs) and job satisfaction. To have a more comprehensive understanding about the relationship between IT satisfaction and job satisfaction, we introduce user-technology fit (job fit and professional fit), which concerns employee users’ perceptions of IT use, as moderator. Moreover, we suggest that job fit and professional fit can mediate the positive impact of IT satisfaction on job satisfaction. Based on an online survey of 229 employee users of ICTs, this study finds that job fit positively moderates the impact of IT satisfaction on job satisfaction. Also, the results approve the mediating effect of both job fit and professional fit. This study contributes to IT performance literature by moving beyond researchers’ focus on ITrelated outcomes, such as employee user satisfaction, to broader job-related outcomes.
Importance of Non-Selective Cation Channel TRPV4 Interaction with Cytoskeleton and Their Reciprocal Regulations in Cultured Cells

Background TRPV4 and the cellular cytoskeleton have each been reported to influence cellular mechanosensitive processes as well as the development of mechanical hyperalgesia. If and how TRPV4 interacts with the microtubule and actin cytoskeleton at a molecular and functional level is not known. Methodology and Principal Findings We investigated the interaction of TRPV4 with cytoskeletal components biochemically, cell biologically by observing morphological changes of DRG-neurons and DRG-neuron-derived F-11 cells, as well as functionally with calcium imaging. We find that TRPV4 physically interacts with tubulin, actin and neurofilament proteins as well as the nociceptive molecules PKCε and CamKII. The C-terminus of TRPV4 is sufficient for the direct interaction with tubulin and actin, both with their soluble and their polymeric forms. Actin and tubulin compete for binding. The interaction with TRPV4 stabilizes microtubules even under depolymerizing conditions in vitro. Accordingly, in cellular systems TRPV4 colocalizes with actin and microtubules enriched structures at submembranous regions. Both expression and activation of TRPV4 induces striking morphological changes affecting lamellipodial, filopodial, growth cone, and neurite structures in non-neuronal cells, in DRG-neuron derived F11 cells, and also in IB4-positive DRG neurons. The functional interaction of TRPV4 and the cytoskeleton is mutual as Taxol, a microtubule stabilizer, reduces the Ca2+-influx via TRPV4. Conclusions and Significance TRPV4 acts as a regulator for both, the microtubule and the actin. In turn, we describe that microtubule dynamics are an important regulator of TRPV4 activity. TRPV4 forms a supra-molecular complex containing cytoskeletal proteins and regulatory kinases. Thereby it can integrate signaling of various intracellular second messengers and signaling cascades, as well as cytoskeletal dynamics. This study points out the existence of cross-talks between non-selective cation channels and cytoskeleton at multiple levels. These cross talks may help us to understand the molecular basis of the Taxol-induced neuropathic pain development commonly observed in cancer patients.
A Validated Analytical Model for Availability Prediction of IPTV Services in VANETs

In vehicular ad hoc networks (VANETs), besides the original applications typically related to traffic safety, we nowadays can observe an increasing trend toward infotainment applications, such as IPTV services. Quality of experience (QoE), as observed by the end users of IPTV, is highly important to guarantee adequate user acceptance for the service. In IPTV, QoE is mainly determined by the availability of TV channels for the users. This paper presents an efficient and rather generally applicable analytical model that allows one to predict the blocking probability of TV channels, both for channel-switching-induced, as well as for handover-induced blocking events. We present the successful validation of the model by means of simulation, and we introduce a new measure for QoE. Numerous case studies illustrate how the analytical model and our new QoE measure can be applied successfully for the dimensioning of IPTV systems, taking into account the QoE requirements of the IPTV service users in strongly diverse traffic scenarios.
Techniques for Concurrent Access to Different Data Structure: A Research Review

Kurukshetra University, Kurukshetra Summary The data structures used in concurrent systems need to be modified. Modifications of shared data structures are done in several steps. If these steps are interleaved with modifications from other tasks, this can result in inconsistency of the data structure. Therefore the data structure needs to be protected from other tasks modifying it while the operation is executing. This can either be done using mutual exclusion(locks)/nonblocking/optimistic methods. The focus of this paper is to give a preview on data structure with efficient and practical approach of concurrency control.
DIRECT SIMULATION FOR WIND INSTRUMENT SYNTHESIS

There are now a number of methods available for generating synthetic sound based on physical models of wind instruments, including digital waveguides, wave digital filters, impedanc e-based methods and those involving impulse responses. Normally such methods are used to simulate the behaviour of the resonator, and the coupling to the excitation mechanism is carried out by making use of simple lumped finite difference schemes or digital filter structures. In almost all cases, a traveling wave, frequ encydomain, or impulse response description of the resonator is used as a starting point—efficient structures may be arrived at wh en the bore is of a particularly simple form, such as a cylinder or cone. In recent years, however, due to the great computing power available, efficiency has become less of a concern—this is es pecially the case for musical instruments which may be well-modelled in 1D, such as wind instruments. In this paper, a fully time-space discrete algorithm for the simulation and synthesis of woodwind instrument sounds is presented; such a method, though somewhat more computationally intensive than an efficient waveguide structure, is still well within the realm of real-time performanc e. The main benefits of such a method are its generality (it is no long er necessary to make any assumptions about bore profile, which m ay be handled in an almost trivial manner), extensibility (i.e ., the model may be generalized to handle nonlinear phenomena directly), ease of programming, and the possibility of direct proofs of numerical stability without invoking frequency domain concepts. Simulation results, sound examples and a graphical user interface, in the Matlab programming language are also presented.
High lethality and minimal variation after acute self-poisoning with carbamate insecticides in Sri Lanka – implications for global suicide prevention

Abstract Background: Highly hazardous organophosphorus (OP) insecticides are responsible for most pesticide poisoning deaths. As they are removed from agricultural practice, they are often replaced by carbamate insecticides of perceived lower toxicity. However, relatively little is known about poisoning with these insecticides. Methods: We prospectively studied 1288 patients self-poisoned with carbamate insecticides admitted to six Sri Lankan hospitals. Clinical outcomes were recorded for each patient and plasma carbamate concentration measured in a sample to confirm the carbamate ingested. Findings: Patients had ingested 3% carbofuran powder (719), carbosulfan EC25 liquid (25% w/v, 389), or fenobucarb EC50 liquid (50% w/v, 127) formulations, carbamate insecticides of WHO Toxicity Classes Ib, II, and II, respectively. Intubation and ventilation was required for 183 (14.2%) patients while 71 (5.5%) died. Compared with carbofuran, poisoning with carbosulfan or fenobucarb was associated with significantly higher risk of death [carbofuran 2.2%; carbosulfan 11.1%, OR 5.5 (95% CI 3.0–9.8); fenobucarb 6.3%, OR 3.0 (1.2–7.1)] and intubation [carbofuran 6.1%; carbosulfan 27.0%, OR 5.7 (3.9–8.3); fenobucarb 18.9%, OR 3.6 (2.1–6.1)]. The clinical presentation and cause of death did not differ markedly between carbamates. Median time to death was similar: carbofuran 42.3 h (IQR 5.5–67.3), carbosulfan 21.3 h (11.5–71.3), and fenobucarb 25.3 h (17.3–72.1) (p = 0.99); no patients showed delayed onset of toxicity akin to the intermediate syndrome seen after OP insecticide poisoning. For survivors, median duration of intubation was 67.8 h (IQR 27.5–118.8) with no difference in duration between carbamates. Reduced GCS at presentation was associated with worse outcome although some patients with carbosulfan died after presentation with normal GCS. Conclusions: We did not find carbamate insecticide self-poisoning to vary markedly according to the carbamate ingested although the case fatality varied according to the concentration and formulation of the insecticide. Carbamate poisoning did not appear to be much less toxic than poisoning with some liquid OP insecticide formulations, e.g., chlorpyrifos EC40, that we have previously noted in these same hospitals (Lancet 2005, 366:1452–1459; QJM 2006, 99:513–522). Replacement of WHO Class II Toxicity OP insecticides in agriculture with high-strength liquid carbamate formulations may not substantially reduce case fatality after pesticide poisoning and, therefore, global suicide rates.
Critical thinking and young children's exploration of picturebook artwork

ABSTRACT The data featured in this article were gathered during a classroom-based research project with Grade 2 (six- and seven-year-old) children. The overall purposes of the study included exploration of how the development of young children's understanding of elements of visual art and design would affect their comprehension, interpretation, and analysis of the artwork in a selection of picturebooks, as well as the subsequent application of the same elements when they created their own multimodal print texts. A discussion of critical thinking is followed by descriptions of the study's guiding theoretical and conceptual frameworks, as well as an overview of relevant literature, the research context and methods, and the data analysis procedures. The findings from the content analysis of the students’ written responses about the artwork of one picturebook are discussed with reference to key concepts associated with critical thinking. The conclusion features a consideration of how students’ critical thinking skills and esthetic development can be enhanced by instruction about elements of visual art and design in picturebooks.
Screening Mosquito House Entry Points as a Potential Method for Integrated Control of Endophagic Filariasis, Arbovirus and Malaria Vectors

Background Partial mosquito-proofing of houses with screens and ceilings has the potential to reduce indoor densities of malaria mosquitoes. We wish to measure whether it will also reduce indoor densities of vectors of neglected tropical diseases. Methodology The main house entry points preferred by anopheline and culicine vectors were determined through controlled experiments using specially designed experimental huts and village houses in Lupiro village, southern Tanzania. The benefit of screening different entry points (eaves, windows and doors) using PVC-coated fibre glass netting material in terms of reduced indoor densities of mosquitoes was evaluated compared to the control. Findings 23,027 mosquitoes were caught with CDC light traps; 77.9% (17,929) were Anopheles gambiae sensu lato, of which 66.2% were An. arabiensis and 33.8% An. gambiae sensu stricto. The remainder comprised 0.2% (50) An. funestus, 10.2% (2359) Culex spp. and 11.6% (2664) Mansonia spp. Screening eaves reduced densities of Anopheles gambiae s. l. (Relative ratio (RR) = 0.91; 95% CI = 0.84, 0.98; P = 0.01); Mansonia africana (RR = 0.43; 95% CI = 0.26, 0.76; P<0.001) and Mansonia uniformis (RR = 0.37; 95% CI = 0.25, 0.56; P<0.001) but not Culex quinquefasciatus, Cx. univittatus or Cx. theileri. Numbers of these species were reduced by screening windows and doors but this was not significant. Significance This study confirms that across Africa, screening eaves protects households against important mosquito vectors of filariasis, Rift Valley Fever and O'Nyong nyong as well as malaria. While full house screening is required to exclude Culex species mosquitoes, screening of eaves alone or fitting ceilings has considerable potential for integrated control of other vectors of filariasis, arbovirus and malaria.
The efficacy and safety of dezocine combined with propofol used in cystoscopy

Purpose: To evaluate the clinical efficacy and safety of using dezocine combined with propofol undergoing painless cystoscopy. Methods: 120 patients who undergoing eystoscopy were randomly divided into three groups: dezocine group (group D), Fentanyl group (group F) and physiological saline (group N), each groups plus propofol through intravenous anesthesia respectively. The MAP (Mean Arterial Pressure), HR (Heart Rate) and SpO2 (Pulse Oxygen Saturation) were observed after anesthesia, The total amounts of propofol, the period of loss consciousness and arousal time were recorded. The sores of postoperative pain, consciousness-sedation and degree of comfort were registered at 15 min, 30 min, 60 min. Results: The MAP and HR at T1 time all significant lower than at T0 time (P<0.05), but the comparative differences between groups was no statistically, the HR and BIS of group N are higher at T2 time than group F and D. At T3 time, the MAP and HR of group F and N were higher than group D (P<0.05). The total amounts of propofol of group F and D were significantly reduced than group N (P<0.05), but the period of loss consciousness between groups were no statistically. The arousal time of group F were significantly shorter than group D and N. The pain of urethra of group D was obviously alleviation compare to group F and N. Conclusion: Dezocine combined with propofol for cystoseopy has big worth on clinical application because it small dosage, Palinesthesia perfect, safety, comfortable and so on.
The Functional Neuroanatomy of Temporal Discrimination

Two identical stimuli, such as a pair of electrical shocks to the skin, are readily perceived as two separate events in time provided the interval between them is sufficiently long. However, as they are presented progressively closer together, there comes a point when the two separate stimuli are perceived as a single stimulus. Damage to posterior parietal cortex, peri-supplementary motor area (peri-SMA), and basal ganglia can disturb this form of temporal discrimination. Our aim was to establish, in healthy subjects, the brain areas that are involved in this process. During functional magnetic resonance imaging scanning, paired electrical pulses, separated by variable inter-stimulus intervals (5-110 msec), were delivered to different sites on one forearm (8-64 mm from the midline). Subjects were required to simply detect the stimulus (control task) or to identify a stimulus property. For temporal discrimination (TD), subjects reported whether they felt one or two stimuli. For spatial discrimination, they reported whether the stimuli were located on the right or left side of the forearm. Subjects reported their choice by pressing a button with the opposite hand. Our results showed that discrimination, as opposed to simply detection, activated several brain areas. Most were common to both discrimination tasks. These included regions of prefrontal cortex, right postcentral gyrus and inferior parietal lobule, basal ganglia, and cerebellum. However, activation of pre-SMA and anterior cingulate was found to be specific to the TD task. This suggests that these two frontal regions may play a role in the temporal processing of somatosensory events.
Intragroup communication in intergroup conflict Influences on social perception and cognition

How we see ourselves and others depend largely on everyday conversations and informal chats. In these conversations, people like to talk about other people and groups – for instance, the perceptions that native Dutch have of non-native Dutch are typically developed in conversations in which non-native people are nor heard. This kind of seemingly harmless communication within groups can play a key role in the development of conflicts between social groups. In this process, perceptions of others are influenced not only by what people discuss (positive aspects) but also by how they discuss this (at individual or group level). This dissertation reveals that a positive conversation about a Moroccan-Dutch person such as Najob Amhali has little effect on the perception of Moroccan-Dutch people as a group. However, a positive conversation about how hospitable and caring Moroccan-Dutch people are as a group improves native Dutch’s perceptions of them. The negative consequences of social categorization can be countered best by mentioning the category’s positive characteristics. However, if people have a negative perception about a group, they by default tend to do exactly the opposite: Information that matches a stereotypic image is discussed at a group level, whereas information that does not match this stereotype is discussed in a more individualizing manner. This implies that natural conversation tendencies facilitate maintenance of stereotypes. The conclusion of this dissertation is that negative categorizing should be countered with positive categorizing.
Is two too early? Assessing toddlers’ phonology

Early identification of phonological disorders is important for Speech Language Pathologists who assess and treat children aged under three years. Normative data justifies identification and standard scores can evaluate intervention that might prevent the negative consequences associated with phonological disorder. Two studies evaluated the reliability and predictive validity of the Toddler Phonology Test (TPT). Study 1 assessed 18 Australian toddlers, comparing their performance with normative data and reassessing them one month later to examine test–retest reliability. Study 2 assessed the predictive validity of the TPT’s quantitative and qualitative normative data by reassessing 24 British children between four and nine months after their first assessment and examining number and type of errors. Study 1 found no significant difference between the first and second assessment one month later for percent consonants and vowels correct but a drop in the number of atypical errors. Positive correlations for all performance measures showed strong test–retest ranking for children. Study 2 indicated that both quantitative and qualitative TPT data predicted phonological development over 4–9 months. Case data suggested that phonological disorder was best predicted by qualitative data. The results indicated that phonological disorder can be reliably diagnosed at two years of age.
