Impact of social comparisons on the developing self-perceptions of learning disabled students.

Learning disabled (LD) children's self-perceptions were investigated using the Perceived Competence Scale for Children (Harter, 1982). This self-report instrument taps children's perceptions of their scholastic and athletic competence, social acceptance, and feelings of global self-worth. Participants in the study were 86 students in Grades 3-8 who attended a public school LD resource room. Results indicated that social comparison processes play an important role in the formation of LD students' perceived academic competence. LD students perceived themselves as becoming less academically competent across the grade span tested when they compared themselves with normally achieving students in their regular classes. When they compared their abilities with LD peers in their resource room, they maintained high perceptions of their own academic competence. Concern for the child's emotional and intellectual wellbeing has led those working with students who evidence learning disabilities to become interested in studies of selfconcept with this population. Because, by definition, learning disabled (LD) students have experienced academic failure, a number of practitioners and researchers have been interested in the extent to which LD students feel poorly about themselves. Research in the area of self-concept with LD students is inconclusive, however. Although a number of studies have revealed that LD students evidence worse feelings about themselves than do normally achieving students (Alley & Deschler, 1979; Black, 1974; Griffiths, 1970; Rogers & Saklofske, 1985; Rosenthal, 1973), other studies have not indicated such differences (Brunner & Starkey, 1974; Donnell, 1975; Endler & Minden, 1972; Ribner, 1978). Silverman and Zigmond (1983) have maintained that the contradictory findings in the literature on self-concept among LD students can be attributed, in part, to the inconsistency of the definitions of both the LD population and the construct of self-concept among studies. Furthermore, methodological differences, weaknesses in research designs, and the lack of data on the equivalence of the various self-concept inventories used preclude any conclusions based on these results.

Genre and Gender in the Structure of Music Preferences

Whereas young audiences are known to distinguish among several types of popular music, there is evidence that the several genres are organized from the listener's standpoint, that music types go together to form “metagenres. ” In addition, it is suggested that, for a variety of reasons, gender is central to the ways in which popular music is used and tastes are organized. This article presents an analysis of the music preference structure of college students based on responses to a variety of music use and preference measures and concludes: first, that the underlying structure of music preference cannot be accounted for by reference to two or three factors but is multivariate; second, that there are crucial differences between males and females in terms of their “mapping” of music types.
Method for Quantitative Analysis of Dramatic Play

A method for the quantitative analysis of dramatic play is presented based on narrative case records in which the following items were isolated: dramatic units, involvement of O requested by S, longest dramatic unit. The longest dramatic units were further analyzed for amount of time, sub-units introduced, intensity, and themes expressed. This method appears potentially useful for intensive study of dramatic play.
Direct Time Domain Modelling of First Return Stroke of Lightning

The four most important factors that govern the return stroke evolution can be identified as: (i) electric field due to charge distributed along the channel, (ii) transient enhancement of conductance by several orders at the bridging regime (iii) the non-linear increase in channel conductance at the propagating current front and (iv) the associated dynamic elec- tromagnetic field which support the evolution of current along the channel. For a more realistic modelling of the lightning return stroke, the present work attempts to consider these aspects in suitable manner. The charge simulation method is employed for evaluating the quasi-static field due to (i). For the dynamic field, the problem involves conduction along a thin structure with open boundary on one side. Further, in order to efficiently represent a vertically extended grounded strike object, as well as, channel of quite arbitrary geometry, boundary based approach is believed to be the ideal choice. Considering these, a time-dependent electric field integral equation (TD-EFIE) along with a sub-sectional collocation form of the method of moments (MoM) is chosen for the numerical field evaluation. The dynamic variation of conduc- tance in the channel other than the bridging zone is modelled by a first order arc equation. For the bridging zone, arc equa- tion which explicitly portray in some sense, accumulation of energy is considered. Accordingly, formulations given by Barannik, Popovic and Toepler were scrutinized for their suitability. After some preliminary simulation studies, a self contained model for the first return stoke of a lightning flash is presented. The stability of the model is verified by running the program for longer durations with different cloud base potentials and cloud base heights. Simulation results are in agreement with the field data on current and velocity decay rate for the first one kilometer height. Also, the relation be- tween the charge density at channel tip and the return stroke current peak favorably compares with the literature.
Complications of Endovascular Polymers Associated With Vascular Introducer Sheaths and Metallic Coils in 3 Patients, With Literature Review

Background Hydrophilic coatings on arterial introducer sheaths reduce the frequency of spasm during cardiac catheterization. Moreover, during treatment of cerebral artery aneurysms, hydrophilic coatings on microcatheters ease their maneuverability, and polymers within embolization coils enhance neointimal fibrosis at the aneurysm neck. Foreign-body giant cell reactions can result when a polymer is stripped from its source. Cases 1 and 2 A 51-year-old man and a 66-year-old woman underwent coronary angiography via the radial artery, using hydrophilic-coated sheaths. They both developed tender lesions at the access site 2 weeks later. Microscopy of resected lesions showed pieces of hydrophilic coating and granulomatous inflammation, as has been reported by others. Case 3 A 58-year-old woman underwent embolization of a ruptured distal right internal carotid artery aneurysm using polymer-containing coils. Nine months later, she began developing multiple right-sided cerebral ring-enhancing lesions. Biopsy revealed granulomas and microabscesses, in which polymer filaments were later identified. To our knowledge, this complication has not been described previously. Conclusions Hydrophilic coating may dislodge and induce a prominent foreign-body granulomatous response or microabscesses. Although the culprit radial artery sheath is now rarely used, embolization coils containing polymers are commonly deployed in clinical practice and may be a source of recurrent inflammatory lesions.
Causes for Query Answers from Databases, Datalog Abduction and View-Updates: The Presence of Integrity Constraints

Causality has been recently introduced in databases, to model, characterize and possibly compute causes for query results (answers). Connections between queryanswer causality, consistency-based diagnosis, database repairs (wrt. integrity constraint violations), abductive diagnosis and the view-update problem have been established. In this work we further investigate connections between query-answer causality and abductive diagnosis and the view-update problem. In this context, we also define and investigate the notion of query-answer causality in the presence of integrity constraints.
Domestic Situated SMS Messaging with Digital Photo Frames

SMS messaging technology allows for short messages to be exchanged between individuals at a relatively low cost. Current SMS messaging technology is limited to person-to-person messaging; many other forms of social communication also allow for person-to-location messaging. This is particularly important for domestic messaging since messages may need to be broadcast to an entire family or household. Some previous work has discussed the creation of display technology to receive SMS messages, but these projects all required custom hardware development in addition to the software components that received and displayed the messages. In this project, I created a comprehensive person-to-location SMS messaging system built on digital photo frames. These photo frames are relatively inexpensive and are readily available. I designed and implemented a software platform and hardware infrastructure to receive, deliver, and render messages to digital photo frames that are located in the home. By rendering messages as images in JPEG format and delivering these images across a local wireless network the photo frames can display SMS messages overlaid on digital photos. I conducted an evaluation study with two families and two flats. Each household was provided with a photo frame and accompanying infrastructure for approximately one month. Households used the photo frame messaging technology regularly, sending 100 messages over the period of the study. Usage patterns varied by household, but overall I found that family members mostly used the system to send informational messages about their location and status, while flats used the system primarily for social communication and for facilitating social interactions. The evaluation study also assessed the use of photo frame technology for this type of situated display application. The limitations of digital photo frames became apparent over the course of the evaluation. Household members found that the inability to scroll through previously received messages, as well as the lack of audible notifications when new messages arrived, precluded their use of the system for urgent messages or for requests that required action. Nevertheless, the households adapted to the characteristics of the technology over the period of the study and found it useful for broadcasting particular types of social and informational messages to the entire flat or family.
New Hepatitis E Virus Genotype in Camels, the Middle East

In a molecular epidemiology study of hepatitis E virus (HEV) in dromedaries in Dubai, United Arab Emirates, HEV was detected in fecal samples from 3 camels. Complete genome sequencing of 2 strains showed >20% overall nucleotide difference to known HEVs. Comparative genomic and phylogenetic analyses revealed a previously unrecognized HEV genotype.
Maximum power point tracking of PV system with backstepping control

This paper proposes a photovoltaic array system connected to converter and battery A backstepping controller is designed for maximizing the output power of the system The controller reduces the error between the desired array voltage, to the obtained voltage under varying temperature and radiation condition by maximum power point tracking, by changing the duty cycle of the switching converter. The stability of the backstepping control is analyzed by means of Lyapunov analysis. The result of simulation clearly illustrates that the designed backstepping control algorithm can be used for improving the output voltage under external parameter variation.
Fibroblast Activation Protein Cleaves and Inactivates Fibroblast Growth Factor 21*

FGF21 is a stress-induced hormone with potent anti-obesity, insulin-sensitizing, and hepatoprotective properties. Although proteolytic cleavage of recombinant human FGF21 in preclinical species has been observed previously, the regulation of endogenously produced FGF21 is not well understood. Here we identify fibroblast activation protein (FAP) as the enzyme that cleaves and inactivates human FGF21. A selective chemical inhibitor, immunodepletion, or genetic deletion of Fap stabilized recombinant human FGF21 in serum. In addition, administration of a selective FAP inhibitor acutely increased circulating intact FGF21 levels in cynomolgus monkeys. On the basis of our findings, we propose selective FAP inhibition as a potential therapeutic approach to increase endogenous FGF21 activity for the treatment of obesity, type 2 diabetes, non-alcoholic steatohepatitis, and related metabolic disorders.

Alco‐pop? The Use of Popular Music in Glasgow Pubs

In recent years popular music studies has witnessed a turn towards concentrating on music at a local level (Cloonan) and its use in what DeNora calls everyday life. In a separate, but overlapping, development there has been a growing interest in the night‐time economy. At an academic level this has included some interest in the role popular music plays in that economy (e.g. Bennett; Björnberg and Stockfelt) and at the UK governmental level it has included responses to “binge drinking” (Home Affairs Select Committee; Prime Minister's Strategy Unit; Scottish Executive) and to licensing.1 But there has been less attention paid to the role that music plays within a key part of that economy—pubs. In this article we examine the use of music in city centre pubs in Glasgow, Scotland. We include the role of music in attracting customers to pubs, the different types of clientele attracted, the relationship between music and alcohol sales, and the ways in which music can act as both a trigger for disorder and a means of preventing it. We develop a typology of uses of music and explore the implications for popular music studies.
Parent education and home‐based behaviour analytic intervention: an examination of parents’ perceptions of outcome

There is convincing evidence that applied behaviour analysis (ABA) offers a highly effective form of intervention for children with autistic spectrum disorder (ASD). There is less evidence, however, about how parents perceive and evaluate ABA programmes. In this paper an examination of parents’ perceptions of outcome is reported. Twenty‐two questionnaires were completed by two groups of parents. The first group had just completed an introductory course in ABA and were in the early stages of implementing ABA programmes with their children. The second group had been involved in ABA education for more than 2 years. Overall, both groups of parents reported a positive impact of ABA on the lives of their children, their family life, and themselves. The long‐term group reported that they had achieved complex goals with their children, whilst the short‐term group reported an immediate positive impact on child and family functioning and parental self‐esteem. Conclusions are drawn in the context of evidence‐based practice.
The block structure spaces of real projective spaces and orthogonal calculus of functors II

Abstract For a finite dimensional real vector space V with inner product, let F(V) be the block structure space, in the sense of surgery theory, of the projective space of V. Continuing a program launched in [Macko, Trans. Amer. Math. Soc. 359: 349–383, 2007], we investigate F as a functor on vector spaces with inner product, relying on functor calculus ideas. It was shown in [Macko, Trans. Amer. Math. Soc. 359: 349–383, 2007] that F agrees with its first Taylor approximation T 1 F (which is a polynomial functor of degree 1) on vector spaces V with dim(V) ≥ 6. To convert this theorem into a functorial homotopy-theoretic description of F(V), one needs to know in addition what T 1 F(V) is when V = 0. Here we show that T 1 F(0) is the standard L-theory space associated with the group ℤ/2, except for a deviation in π0. The main corollary is a functorial two-stage decomposition of F(V) for dim(V) ≥ 6 which has the L-theory of the group ℤ/2 as one layer, and a form of unreduced homology of ℝP(V) with coefficients in the L-theory of the trivial group as the other layer. Except for dimension shifts, these are also the layers in the traditional Sullivan-Wall-Quinn-Ranicki decomposition of F(V). But the dimension shifts are serious and the SWQR decomposition of F(V) is not functorial in V. Because of the functoriality, our analysis of F(V) remains meaningful and valid when V = ℝ∞.
Picowatt, 0.45–0.6 V Self-Biased Subthreshold CMOS Voltage Reference

In this paper, a self-biased temperature-compensated CMOS voltage reference operating at picowatt-level power consumption is presented. The core of the proposed circuit is the self-cascode MOSFET (SCM) and two variants are explored: a self-biased SCM (SBSCM) and a self-biased NMOS (SBNMOS) voltage reference. Power consumption and silicon area are remarkably reduced by combining subthreshold operation with a self-biased scheme. Trimming techniques for both circuits are discussed aiming at the reduction of the process variations impact. The proposed circuits were fabricated in a standard 0.18- $\mu \text{m}$ CMOS process. Measurement results from 24 samples of the same batch show that both circuits herein proposed can operate at 0.45/0.6 V minimum supply voltage, consuming merely 55/184 pW at room temperature. Temperature coefficient (TC) around 104/495 ppm/°C across a temperature range from 0 to 120 °C was measured. Employment of a trimming scheme allows a reduction of the average TC to 72.4/11.6 ppm/°C for the same temperature range. Both variants of the proposed circuit achieve a line sensitivity of 0.15/0.11 %/V and a power supply rejection better than −44/−45 dB from 10 to 10 kHz. In addition, SBSCM and SBNMOS prototypes occupy a silicon area of 0.002 and 0.0017 mm2, respectively.
Improving Diabetic Retinopathy Screening Ratios Using Telemedicine-Based Digital Retinal Imaging Technology

OBJECTIVE—To evaluate the impact of a telemedicine, digital retinal imaging strategy on diabetic retinopathy screening rates in an inner-city primary care clinic. RESEARCH DESIGN AND METHODS—This retrospective cohort study included all diabetic patients aged ≥18 years (n = 495) seen at Vine Hill Community Clinic between 1 September 2003 and 31 August 2004. Patients were offered ophthalmology referral or digital screening. Patients choosing referral received the next available (within 3 months) appointment at the Vanderbilt Eye Clinic; patients choosing digital screening were screened during the visit. RESULTS—Retinal screening was documented for 293 (59.2%) patients, a significant improvement compared with the 23% baseline rate. Of 293 patients screened, 92 (31.4%) were screened in ophthalmology, and 201 (68.6%) were digitally screened. Among the 201 digitally screened patients, 104 (51.7%) screened negative and were advised to rescreen in 1 year, 75 (37.3%) screened positive and were nonurgently referred to ophthalmology, and 22 (11.0%) screened positive for sight-threatening eye disease and were urgently referred for ophthalmological follow-up. Digital imaging technical failure rate was 0.5%. Referral status was associated with race/ethnicity (χ2 = 7.9, P < 0.02) with whites more likely to screen negative than non-whites (62.4 vs. 47.8%, respectively). Sight-threatening disease among non-whites (14.7%) was more than double that observed for whites (5.9%). CONCLUSIONS—Digital imaging technology in the primary care visit can significantly improve screening rates over conventional methods, increase access to recommended diabetic eye care, and focus specialty care on medically indigent patients with greatest need.
Early emergency management of acute decompensated heart failure

Purpose of reviewAcute decompensated heart failure (ADHF) is characterized by a complex spectrum of pathophysiology that emerges as a common clinical disease state, which manifests as a failure of the circulation to provide for the needs of the body systems. Whereas ADHF is often characterized by the findings of pulmonary congestion and dyspnea, a variety of clinical presentations are possible, with each requiring differing management strategies. This review examines the approach of the four-quadrant clinical profile for differentiation of the ADHF patient during the emergent resuscitative phase of the decompensation. Recent findingsClinical and diagnostic information can be used to determine the relative degree of pulmonary congestion and peripheral tissue perfusion in patients suspected of ADHF. This information can be used in a four-quadrant approach to differentiate patients into pathophysiologic categories. These profiles can then be translated into management strategies from a physiology based perspective in which the specific mechanisms of the failure are targeted. SummaryADHF can present in a variety of clinical forms in the emergent setting. Categorization of the ADHF patient according to their individual hemodynamic profile can assist in management decisions during the emergent resuscitative phase of the decompensation based upon an approach that targets causative pathophysiologic mechanisms.
Algebraic solution for geometry from dimensional constraints

We investigate general configurations of distance and angle dimensions between points, lines and circles on a plane. A simple graphical representation is described for the system of coupled ctuadratic equations which results from treating the geometries as variables and the dimensions as defining equations. For many configurations of practical interest we show that these equations are poorly suited to numerical solution.
On interdisciplinary movements: The development of a network of support around Foucaultian perspectives in accounting research

Abstract This paper seeks to better understand interdisciplinary movements in the making. Our investigation focuses on the processes through which a network of support surrounding Michel Foucault's ideas originally developed in the sociological and organizational stream of accounting research. Drawing on the sociology of translation, we first examine how a network of support emerged around the journal Accounting, Organizations and Society (AOS), which is generally perceived as the main vector of dissemination of sociological and organizational accounting research. Our investigation then focuses on how Foucault's ideas, a few years after the founding of AOS, came to the attention of a group of accounting academics in the UK – a group in which the editor-in-chief of AOS was a key actor. We also examine how a network of support surrounding Foucault's ideas subsequently developed in the greater accounting research community. Our analysis emphasizes the role of epistemological uncertainty in the constitution of networks of support around journals and ideas, and the role of trials of strength (Latour, 1987) in fuelling or mitigating this uncertainty, thereby influencing actors' interests and commitments to particular networks. Our analysis also highlights the critical role that imitation and social differentiation play in the travel of ideas between scientific fields and the creation of scientific knowledge.
