Using social knowledge while interacting at the classroom sand center: Facework and cohesion strategies

The goal of this study is to inform teachers’ practice by identifying specific language strategies that young children use in their play and suggesting ways that teachers can build on our findings to support students’ language and literacy. Deductive analyses of video-recordings of 5-year old children playing at the sand center revealed that children used cohesive strategies, such as repetitions and conjunctions, to tie together the ideas from one speaker to the next, in order to maintain the flow of the play. Children also used facework strategies, such as complimenting peers, softening regulatory language with words such as “just,” and showing interest in others’ activities. These strategies helped children to build relationships with peers and enhance their positive self-esteem as members of the play group. Children used language primarily for imaginative purposes, in addition to communicating information, regulating others’ behavior, and expressing their individuality and emotional responses to activities at the sand center. Primary teachers may find these results useful for guiding assessment of children’s knowledge of and flexibility in using linguistic and semiotic resources to achieve social purposes and to create cohesive narratives in informal interactions.
Psychometric evaluation of the polish version of the MINI-ICF-APP – a concise measure of limitations on activity and restrictions on participation according to the international classification of functioning, disability and health (ICF) – in people with mental disorders

Purpose: The Mini-ICF-APP is a simple, practical tool measuring activity limitations and participation restrictions in mental disorders according to the principles and categories of the International Classification of Functioning, Disability and Health (ICF). The aim of the study was to determine the basic psychometric properties of the Polish language version of the Mini-ICF-APP. Method: A total of 58 patients in the early stages of recovery were included. Each of them was independently assessed by three clinicians with varied professional backgrounds (psychiatrists, psychologists and other therapists) using the Mini-ICF-APP and measures of psychopathology (Brief Psychiatric Rating Scale – BPRS) and level of psychosocial functioning (Global Assessment of Functioning Scale – GAF; Personal and Social Performance Scale – PSP). Feasibility, reliability (internal consistency and inter-rater agreement), and validity (content, criterion and construct) were analysed. Results: Feasibility was concluded on the basis of positive feedback from clinicians, diversity of distribution and good item performance. Internal consistency was high, both when analysed jointly and separately for particular groups of clinicians. Measures of inter-rater agreement reached high values for the scale and were significant for each item. Criterion validity was indicated by high correlations with the GAF and the PSP, and slightly weaker with the BPRS. The construct validity of the Mini-ICF-APP was inferred ISSN: 1230-2813 volume 26 / Issue 1 2017 ADVANCES IN PSYCHIATRY & NEUROLOGY
On the added-mass force and moment and the vortex projection method. Application to thin airfoils

The force and moment on a solid body in non-uniform motion in an incompressible fluid are derived following the projection technique of Quartapelle and Napolitano (1983 AIAA J. 21, 911–913) and Chang (1992 Proc. R. Soc. A-Math. Phys. Engng Sci. 437, 517–525) in a compact vector form, identifying added-mass terms equivalent to those resulting from potential-flow theory. The expressions are formally much simpler in a non-inertial frame fixed relative to the body, though general relations for an inertial frame are also given. Approximate analytical expressions are obtained for the force and moment on two-dimensional elliptic bodies at high Reynolds numbers, each one consisting of just two terms: an added-mass component and a vortex term (integration of a projection of Lamb’s vector). The formulation is applied to a flat plate in steady motion and in non-uniform oscillatory motion, recovering classical results in both cases, but adding new physical insight about the origin of the different elements of the force and moment. It is shown that, in the non-steady motion, the added-mass components of the force and moment cancel out with part of their respective vortex terms, so that all the force and moment come from appropriate projections of Lamb’s vector, including the supposedly added-mass force and moment. This result indicates that one has to be cautious about simplified aerodynamic models for flapping foils based on a simple separation of the added-mass and vortical components of the force and moment. The present results can be used to obtain analytically the force and moment on an ellipse with arbitrary motion through an incompressible fluid at high Reynolds numbers.
Audience participation in a dance-club context: Design of a system for collaborative creation of visuals

We investigated possibilities of improved interaction between artist and audience in the context of the dance club culture. Music club events are already highly interactive and collaborative experiences, so we focused on the role of media and amateur content creation. We identified a number of design challenges and constraints and developed a design concept accordingly. Our system allows for audience members to collaborate with a professional VJ (“video-” or “visual jockey”) in the selection and creation of live visuals that will be displayed alongside and fitting to the music on a screen at the dance-floor. The audience members interact with the system through a physical “station” that allows input and creation of visual material. The VJ then selects from that material and arranges a engaging live presentation.
The Performance of SCI Memory Hierarchies

This paper presents a simulation-based performance evaluation of a shared-memory multiprocessor using the Scalable Coherent Interface (IEEE 1596). The machines are assembled with one to 16 processors connected in a ring. The multiprocessor's memory hierarchy consists of split primary caches, coherent secondary caches and memory. For a workload of two parallel loops and three thread-based programs, secondary cache latency has the strongest impact on performance. For programs with high miss ratios, 16-node rings exhibit high network congestion whereas 4and 8-node rings perform better. With these same programs, doubling the processor speed yields between 20 and 70% speed gains with higher gains on the smaller rings.
Adaptive PID feedback control for the longitudinal dynamics of driver-assisted vehicles in mixed traffic

Vehicles equipped with varying levels of automation and connection are starting to share the road with conventional vehicles. This provides new opportunities to design and test systems to control the acceleration dynamics of those equipped vehicles in mixed traffic environment contexts, with the global aim to globally reduce traffic congestion and increase traffic safety. Recent work has been focusing on proposing solutions to this problem by applying modern control theory, such as optimal control, ℋ∞ control. However, such approaches tend to be computationally expensive or do not take into account the actuators limitations and the safety constraints. For this reason, as well as for the sake of simplicity, in this paper we investigate the design of classic PID controllers to control the acceleration of vehicles equipped with Automated Driving Systems. We consider that each vehicle updates its acceleration according to a car-following model with specific behavioural parameters, thereby accounting for the variability of drivers' behaviours, and we assume that the longitudinal acceleration dynamics of only a proportion of vehicles can be controlled. After linearising the system about its equilibrium state, we show that each vehicle speed to acceleration transfer function reduces to a second order system written as a function of the equilibrium state and the behavioural parameters of the vehicle. We validate this formulation in simulation considering PBRS acceleration inputs. Selecting the set point as the equilibrium speed, an adaptive PID controller is then derived for each vehicle, considering the behavioural parameters. We then discuss set point weighting to avoid propagation of measurement errors, integrator wind-up to consider limitations of the actuators and safety constraints, and tuning of the controllers. Simulations highlight that the designed controllers are able to remove traffic flow instabilities even with a low proportion of equipped vehicles in the traffic flow.
Acute Necrotising Rheumatic Arteritis in a Child

It has for some time been known that acute rheumatism does not affect only the heart but may produce lesions elsewhere in the cardiovascular system as well as in the joints, subcutaneous tissues and central nervous system. In the aorta, the disease process usually begins in the adventitia and only rarely extends beyond the outer third of the media. In the case to be described there was marked change in the intima, not only of the aorta but of the pulmonary arteries.
A Graph-based New Amortization Scheme for Multicast Streams Authentication

We present a graph-based new amortization scheme for multicast streams authentication that achieves stronger resistance against packet loss and reduces the overhead in the same time. The hash chains of the existing amortization schemes have no systematic way to construct them, the construction had been determined by simulation. These schemes lack the theoretical model that helps in determining the values of the parameters and measuring the eciency metrics of the authentication schemes. The proposed scheme in this paper consists of multiple connected chains, each chain connects some packets together. The parameters values of the hash chain of our scheme is determined in advance and the hash chain is constructed systematically. We also introduce mathematical tools that help in measuring the eciency metrics such the authentication probability, the loss resistance and the overhead. The number of chains in our model plays the main role in the eciency of our scheme in terms of loss resistance and overhead. High authentication probability can be achieved by increasing the number of hashes that are appended to the signature packet and by increasing the number of packets that contain the hash of a previous packet.
A Deep Neural Network Compression Pipeline: Pruning, Quantization, Huffman Encoding

Neural networks are both computationally intensive and memory intensive, making them difficult to deploy on embedded systems with limited hardware resources. To address this limitation, We introduce a three stage pipeline: pruning, quantization and Huffman encoding, that work together to reduce the storage requirement of neural networks by 35× to 49× without affecting their accuracy. Our method first prunes the network by learning only the important connections. Next, we quantize the weights to enforce weight sharing, finally, we apply Huffman encoding. After the first two steps we retrain the network to fine tune the remaining connections and the quantized centroids. Pruning, reduces the number of connections by 9× to 13×; Quantization then reduces the number of bits that represent each connection from 32 to 5. On the ImageNet dataset, our method reduced the storage required by AlexNet by 35×, from 240MB to 6.9MB, without loss of accuracy. Our method reduced the size of VGG16 by 49× from 552MB to 11.3MB, again with no loss of accuracy. This allows fitting the model into on-chip SRAM cache rather than off-chip DRAM memory, which has 180× less access energy.
Can the difficulty level reached in computer-based training predict results in x-ray image interpretation tests?

As scientific studies have shown, the performance of airport security screening officers in x-ray image interpretation depends critically on individual abilities and visual knowledge acquired through class-room, computer-based (CBT) and on-the job training. The effectiveness of adaptive CBT in increasing the efficiency in x-ray image interpretation of screening officers could be verified in several studies.
Age-specific FSH levels as a tool for appropriate patient counselling in assisted reproduction.

BACKGROUND The purpose of this study was to assess whether, even within a normal FSH range (< or =10 mU/ml), age-specific FSH levels are predictive of ovarian reserve. METHODS Between January 1998 and December 2001, 535 women, undergoing controlled ovarian stimulation with 225 IU of recombinant (rec) FSH and 75 IU of recLH, were included in this retrospective cohort study. Criteria for enrolment were: age 25-40 years, basal FSH (b-FSH) < or =10 mU/ml and basal LH < or =12 mU/ml. Patients were assigned to three age groups (group I: 25-29 years; group II: 30-35 years; and group III: 36-40 years). Each age group was divided into quartiles according to b-FSH levels, comparing the lowest and highest b-FSH quartiles for basal hormonal patterns and outcome-related parameters. RESULTS At ages 25-35 years, women in the lowest FSH quartiles demonstrated significantly increased numbers of oocytes at retrieval (group I: low b-FSH quartile 8.4 +/- 3.7 versus high b-FSH quartile 6.4 +/- 2.7, P < 0.02; group II: 7.5 +/- 4.0 versus 6.3 +/- 3.0, P < 0.047), whereas no difference with regard to oocyte yield was observed in patients above age 35 (group III: low b-FSH quartile 5.5 +/- 3.1 versus high b-FSH quartile 5.6 +/- 3.5). No statistical correlation was found between FSH quartiles and clinical pregnancy rates or miscarriage. CONCLUSIONS In young women, age-specific high b-FSH levels, even within normal ranges, are associated with significantly reduced numbers of oocytes retrieved. B-FSH concentrations should, therefore, be interpreted in an age-specific manner to allow for appropriate patient counselling in IVF.
That’s My Truth: Evidence for Involuntary Opinion Confirmation

Past research has investigated deliberate mental acts that allow people to remain entrenched in their convictions. The purpose of the current investigation was to examine whether opinion-confirmation processes can occur involuntarily. We conducted experiments wherein participants made speeded judgments of the grammatical accuracy of statements pertaining to various matters of opinion, and subsequently rated their agreement with those statements. The results show that participants more readily verify the grammaticality of a statement when it corresponds to their opinion. These findings may help explain why opinions are sometimes change resistant, in showing that acceptance (rejection) of confirmatory (contradictory) opinions can occur involuntarily. We discuss possible applications of the paradigm described herein.
Saline or albumin for fluid resuscitation in patients with traumatic brain injury.

BACKGROUND The Saline versus Albumin Fluid Evaluation study suggested that patients with traumatic brain injury resuscitated with albumin had a higher mortality rate than those resuscitated with saline. We conducted a post hoc follow-up study of patients with traumatic brain injury who were enrolled in the study. METHODS For patients with traumatic brain injury (i.e., a history of trauma, evidence of head trauma on a computed tomographic [CT] scan, and a score of < or =13 on the Glasgow Coma Scale [GCS]), we recorded baseline characteristics from case-report forms, clinical records, and CT scans and determined vital status and functional neurologic outcomes 24 months after randomization. RESULTS We followed 460 patients, of whom 231 (50.2%) received albumin and 229 (49.8%) received saline. The subgroup of patients with GCS scores of 3 to 8 were classified as having severe brain injury (160 [69.3%] in the albumin group and 158 [69.0%] in the saline group). Demographic characteristics and indexes of severity of brain injury were similar at baseline. At 24 months, 71 of 214 patients in the albumin group (33.2%) had died, as compared with 42 of 206 in the saline group (20.4%) (relative risk, 1.63; 95% confidence interval [CI], 1.17 to 2.26; P=0.003). Among patients with severe brain injury, 61 of 146 patients in the albumin group (41.8%) died, as compared with 32 of 144 in the saline group (22.2%) (relative risk, 1.88; 95% CI, 1.31 to 2.70; P<0.001); among patients with GCS scores of 9 to 12, death occurred in 8 of 50 patients in the albumin group (16.0%) and 8 of 37 in the saline group (21.6%) (relative risk, 0.74; 95% CI, 0.31 to 1.79; P=0.50). CONCLUSIONS In this post hoc study of critically ill patients with traumatic brain injury, fluid resuscitation with albumin was associated with higher mortality rates than was resuscitation with saline.

The Association of Peroxisome Proliferator-Activated Receptor δ and Additional Gene-Gene Interaction with C-Reactive Protein in Chinese Population

Aims. To examine the association between 4 single nucleotide polymorphisms (SNPs) of peroxisome proliferator-activated receptors δ (PPARδ) polymorphisms and C-reactive protein (CRP) level and additional gene-gene interaction. Methods. Line regression analysis was performed to verify polymorphism association between SNP and CRP levels. Generalized multifactor dimensionality reduction (GMDR) was employed to analyze the interaction. Results. A total of 1028 subjects (538 men, 490 women) were selected. The carriers of the C allele (TC or CC) of rs2016520 were associated with a significant decreased level of CRP, regression coefficients was −0.338, and standard error was 0.104 (p = 0.001). The carriers of the G allele (CG or GG) of rs9794 were also significantly associated with decreased level of CRP, regression coefficients was −0.219, and standard error was 0.114 (p = 0.012). We also found a potential gene-gene interaction between rs2016520 and rs9794. Subjects with rs2016520-TC or CC, rs9794-CG or GG genotypes have lowest CRP level, difference (95% CI) = −0.50 (−0.69 to −0.21) (p < 0.001), compared to subjects with rs2016520-TT and rs9794-CC genotypes. Conclusions. rs2016520 and rs9794 minor allele of PPARδ and combined effect between the two SNP were associated with decreased CRP level.
The Causal Mechanisms of Environmentally Responsible Behaviors Using Value Orientations and Recreation Specialization

Abstract With human activities a major cause of environmental problems, there has been an increasing interest in understanding individuals’ environmentally responsible behavior (ERB). Numerous variables such as value orientations and recreation specialization are known to affect the process of fostering specific and general ERB. However, understanding underlying causal relationships is not easy due to the nature of causal inference using observational data. This study attempts to clarify causal mechanisms to explain the process of individuals’ engagement in general ERB from value orientations and recreation specialization via site- and activity-specific ERB using the directed acyclic graph (DAG) theory. The data came from recreational boaters registered in Michigan. Results showed that an initially constructed causal path model was considerably revised using the DAG, and subsequently structural equation modeling analysis was conducted to examine the causal relationships of the revised model. Diverse managerial and policy-related implications are discussed.
Unscheduled Return Visits and Leaving the Chest Pain Unit Against Medical Advice

Background: Rate of Unscheduled Return Visits (URVs) to the Emergency Department has been considered as a key indicator for evaluating the quality of the Emergency Department care for decades. A higher rate of URVs can have a negative impact on the quality of health care. Investigations of the reasons for these returns have indicated that many of these visits can be preventable. Objectives: Given that there are no clear findings about the frequency and reasons for 72 hours URVs to the Chest Pain Unit (CPU), in the present study, we investigated the causes of 72 hours URVs to our CPU in order to find out the inadequacies, and propose preventive strategies. Patients and Methods: This research was a single-center retrospective case control study in the setting of CPU of Tehran Heart Center (a 460-bed, tertiary-care teaching hospital), Tehran, Iran. The medical records of the patients who were presented to our CPU with the chief complaint of chest pain between December 28th, 2010 and February 28th, 2011 were reviewed. Of the 6247 eligible patients, forty-nine URVs that fulfilled our criteria were identified. The control group consisted of 196 patients who did not return to the Emergency Department during our study period. Results: Patient-related factors accounted for most 72 hours URVs (49%). Multivariable analysis revealed that in our CPU, leaving Against medical advice was the most important predictor for 72 hours URVs (P value < 0.001). Additionally, male sex, history of hypertension, first-visit disposition to observation unit and age were the other factors associated with URVs. Conclusions: Considering that the most frequent reason for our URVs was patient-related factors, where all cases had left the CPU Against Medical Advice (AMA) during their first attendance, we recommend that further appropriate strategies be devised to prevent leaving against medical advice.
