Storytelling in Organizations: Facts, Fictions, and Fantasies

Myths, stories, and folklore are part of the fabric and life of all organizations, enabling us to understand, identify, and communicate the character of the organization - its ambitions, conflicts, and peculiarities. Drawing on extensive fieldwork of storytelling in five organizations, this book argues that stories open valuable windows into the emotional and symbolic lives of organizations. By collecting stoires in different organizations, by listening and comparing different accounts, by investigating how narratives are constructed around specific events, by examining which events in an organization's history generate stories and which ones fail to do so, researchers can gain access to deeper organizational realities, closely linked to their members' experiences. In this way, stories enable researchers to study organizational politics, culture, and change in uniquely illuminating ways, revealing how wider organizational issues are viewed, commented upon, and worked upon by their members. The book's first part develops the theory of storytelling by building on various approaches, including narrative, folkloric, ethnographic, symbolic, social constructionist, and psychoanalytic, while the second offers a set of four studies which make use of stories in exploring particular aspects of organizational life.
Needed: An agenda for equity in mathematics education

The purpose of this special issue of the Peabody Journal of Education is to help bring issues of equity to the fore of the current mathematics education reform movement. Over the past decade, we have been inundated with studies, reports, and policy initiatives based on the belief that the American educational system is in crisis. A main focus of that concern has revolved around the teaching of school mathematics. We agree with many of the concerns that underlie calls for reform and note that public education has undergone similar periods of crisis and reform at least since the formation of the common school in the late 1800s. Yet mathematics educators should be concerned that issues of
Conducting a Meta-Analysis of Counseling Outcome Research

A meta-analysis is a quantitative research procedure used to synthesize the results of many similar empirical studies on a topic of interest. A 12-step process for conducting a meta-analysis of counseling outcome research is presented, and the process is demonstrated using a small-scale application of eight published studies exploring the effects of cognitive–behavioral therapy on participants with posttraumatic stress disorder.
Speech Emotion Recognition Based on Rough Set and SVM

Speech emotion recognition is becoming more and more important in such computer application fields as health care, children education, etc. There are a few works have been done on speech emotion recognition using such methods as ANN, SVM, etc in the last years. Traditional feature selection method used in speech emotion recognition is computationally too expensive to determine an optimum or suboptimum feature subset. In this paper, a novel approach based on rough set theory and SVM for speech emotion recognition is proposed. The experiment results show this approach can reduce the calculation cost while keeping high recognition rate
Trigger-Action Programming in the Wild: An Analysis of 200,000 IFTTT Recipes

While researchers have long investigated end-user programming using a trigger-action (if-then) model, the website IFTTT is among the first instances of this paradigm being used on a large scale. To understand what IFTTT users are creating, we scraped the 224,590 programs shared publicly on IFTTT as of September 2015 and are releasing this dataset to spur future research. We characterize aspects of these programs and the IFTTT ecosystem over time. We find a large number of users are crafting a diverse set of end-user programs---over 100,000 different users have shared programs. These programs represent a very broad array of connections that appear to fill gaps in functionality, yet users often duplicate others' programs.
Ultrasound of the Placenta

This review covers ultrasound evaluation of the normal and abnormal placenta with clinical correlation. Normal placental function is essential for a healthy pregnancy outcome as well as for maternal, fetal, childhood, and adult health. Abnormal placental function may result in a compromised pregnancy, creating pathology for the fetus and mother alike. Despite the fact that placental anatomy, function, and location has far-reaching effects for the parents and the developing offspring, ultrasound examination of the placenta is often considered secondary to the fetus by expectant parents and sonographers as well. Location, size, shape, and architecture are easily ascertained with two-dimensional techniques. Three-dimensional ultrasound and Doppler techniques have opened up the frontier of placental function and have set the stage to make placental evaluation as fascinating as that of the fetus.
International students and language support: A new survey

ABSTRACT English Language support is arguably the most important academic support service which British institutions can offer to their international students. However, it is unlikely that this service will be of high quality unless it is provided by staff who are adequately resourced and whose work is acknowledged by the institution as playing an important part in a responsible recruitment strategy. The results of this survey offer insights into language support provision and the institutional position of the staff providing this service.
An RCDD snubber for a bidirectional flyback converter

Increased usage of renewable energy sources has boosted the demand for power electronics converters. Indeed, the DC/DC flyback converter is nowadays frequently used in applications where isolation is required, due to its low component count, simple structure and high energy efficiency. One of the major challenges faced in a flyback converter is the excess voltage stress sensed by its semiconductor devices, because of the interrupted current flow through its transformer leakage inductances. In this paper, a high-efficient bidirectional flyback converter, operating in discontinuous conduction mode, is examined with an integrated RCDD snubber. Additionally, experimental comparison where the converter runs with a typical RCD and RCDD snubber network, is done. Experimental results on an IGBT-based bidirectional flyback converter validate the applicability of the RCDD snubber demonstrating energy efficiency above 90%. Furthermore, the operation of the bidirectional converter with the employed snubber is thoroughly analysed and an appropriate mathematical analysis is conducted highlighting all the design specifications of the proposed snubber.
Performance variability in software product lines: a case study in the telecommunication domain

In the research on software product lines, product variants typically differ by their functionality, and quality attributes are more or less similar across products. To accumulate empirical evidence, this paper presents a descriptive case study of performance variability in a software product line of mobile network base stations. The goal is to study the motivation to vary performance, and the strategy for realizing performance variability in the product line architecture. The results highlight that the evolution of customer needs motivates performance variability; performance variability can be realized either with software or hardware variability strategy, with the latter often being prevailing; and the software strategy can be kept focused by downgrading performance.
Quantitative Evaluation of the Substantially Variable Morphology and Function of the Left Atrial Appendage and Its Relation with Adjacent Structures

Objective To investigate quantitatively the morphology, anatomy and function of the left atrial appendage (LAA) and its relation with adjacent structures. Materials and Methods A total of 860 patients (533 men, 62.0%, age 55.9±10.4 year) who had cardiac multidetector computed tomography angiography from May to October 2012 were enrolled for analysis. Results Seven types and 6 subtypes of LAA morphology were found with Type 2 being the most prevalent. Type 5 was more significantly (P<0.05) present in women (8.0%) than in men (4.2%). LAA orifice was oval in 81.5%, triangular in 7.3%, semicircular in 4%, water drop-like in 3.2%, round in 2.4% and foot-like in 1.6%. The LAA orifice had a significantly greater (P<0.01) major axis in men (24.79±3.81) than in women (22.68±4.07). The LAA orifice long axis was significantly (P<0.05) positively correlated with the height, weight and surface area of the patient. The LAA morphology parameters displayed strong positive correlation with the left atrium volume, aortic cross area long axis or LSPV long axis but poor correlation with the height, weight, surface area and vertebral body height of the patients. Four types of LAA ridge were identified: AI, AII, B and C with the distribution of 17.6%, 69.9%, 5.9% and 6.6%, respectively. The LAA had a significantly (P<0.05) greater distance from its orifice to the mitral ring in women than in men. The LAA had two filling and two emptying processes with the greatest volume at 45% phase but the least volume at 5% phase. The LAA maximal, minimal and emptying volumes were all significantly (P<0.05) positively correlated with the body height, weight and surface area, whereas the LAA ejection fraction had an inverse correlation with the LAA minimal volume but no correlation with the maximal volume. Conclusion The LAA has substantially variable morphologies and relation with the adjacent structures, which may be helpful in guiding the LAA trans-catheter occlusion or catheter ablation procedures.
Proximate Sources of Collective Teacher Efficacy.

Purpose – Recent scholarship has augmented Bandura's theory underlying efficacy formation by pointing to more proximate sources of efficacy information involved in forming collective teacher efficacy. These proximate sources of efficacy information theoretically shape a teacher's perception of the teaching context, operationalizing the difficulty of the teaching task that faces the school and the faculty's collective competence to be successful under specific conditions. The purpose of this study was to examine the influence of three contextual variables: socioeconomic status, school level, and school structure on teacher perceptions of collective efficacy.Design/methodology/approach – School level data were collected from a cross‐section of 79 schools in a Midwestern state. Data were analyzed at the school level using hierarchical multiple regression to determine the incremental variance in collective teacher efficacy beliefs attributed to contextual variables after accounting for the effect of prior aca.
The Contribution of Daniel C. Dennett's Philosophy of Mind to French Cognitive Policy Analysis

French cognitive policy analysis, with its frame of reference theory, assumes that meaning structures public action. The purpose of this article is to show, based on the work of Daniel C. Dennett, that the philosophy of mind may renew the analysis of the theoretical limitations encountered by the frame of reference theory. The soft realism concerning the existence of mental states which Dennett defends provides an opening for a dialogue between cognitive science and public policy analysis.
Developing Socially Just Teachers

This interpretive study investigated how 12 graduates from a justice-oriented teacher preparation program described their teaching goals, practices, and influences on those practices after their 1st year of teaching in an urban school. Relationships among these teachers’ orientations toward socially just teaching, self-reported socially just teaching practices, and self-reported preprogram, program, and postprogram influences were explored. Teachers who were individually and structurally oriented exhibited a sociocultural consciousness and described socially just teaching in various combinations of culturally responsive pedagogies, consciousness-raising, and advocacy; whereas individually oriented teachers focused primarily on “color-blind” caring relationships with their students. Factors that seemed to influence a more structural orientation to socially just teaching included (a) cross-cultural experiences before and during teacher preparation, (b) program course content and field experiences that challenged previous thinking, and (c) administrative and collegial support during the 1st year of teaching. Implications for teacher education practice and research are discussed.
Ve methods of describing structure formation in the Lemaitre-Tolman model

We describe several new ways of specifying the behavior of Lemaoˆtre-Tolman (LT) models, in each case presenting the method for obtaining the LT arbitrary functions from the given data, and the conditions for existence of such solutions. In addition to our previously considered ‘‘boundary conditions,’’ the new ones include: a simultaneous big bang, a homogeneous density or velocity distribution in the asymptotic future, a simultaneous big crunch, a simultaneous time of maximal expansion, a chosen density or velocity distribution in the asymptotic future, only growing or only decaying fluctuations. Since these conditions are combined in pairs to specify a particular model, this considerably increases the possible ways of designing LT models with desired properties.
Immigrant Employment Success in Canada: Examining the Rate of Obtaining a Job Match

This study employs longitudinal data to examine the rate at which recent immigrants to Canada obtain employment matching their previous or intended occupations. Socio-demographic factors such as visible minority status and area of residence are found to influence the rate at which this cohort of immigrants obtains job matches. Human capital factors also have a significant impact. An examination of occupational characteristics reveals that immigrants who seek high-status occupations obtain job matches at slower rates than those seeking lower-status occupations.
Prediction, evolution and privacy in social and affiliation networks

In the last few years, there has been a growing interest in studying online social and affiliation networks, leading to a new category of inference problems that consider the actor characteristics and their social environments. These problems have a variety of applications, from creating more effective marketing campaigns to designing better personalized services. Predictive statistical models allow learning hidden information automatically in these networks but also bring many privacy concerns. Three of the main challenges that I address in my thesis are understanding 1) how the complex observed and unobserved relationships among actors can help in building better behavior models, and in designing more accurate predictive algorithms, 2) what are the processes that drive the network growth and link formation, and 3) what are the implications of predictive algorithms to the privacy of users who share content online. The majority of previous work in prediction, evolution and privacy in online social networks has concentrated on the single-mode networks which form around user-user links, such as friendship and email communication. However, single-mode networks often co-exist with two-mode affiliation networks in which users are linked to other entities, such as social groups, online content and events. We study the interplay between these two types of networks and show that analyzing these higher-order interactions can reveal dependencies that are difficult to extract from the pair-wise interactions alone. In particular, we present our contributions to the challenging problems of collective classification, link prediction, network evolution, anonymization and preserving privacy in social and affiliation networks. We evaluate our models on real-world data sets from well-known online social networks, such as Flickr, Facebook, Dogster and LiveJournal.
Treatment of Persistent Phenothiazine-induced Oral Dyskinesia

Since the first description of persistent oral dyskinesia following phenothiazine treatment by Sigwald in 1956 a good deal of evidence has accumulated indicating the regular occurrence of this syndrome. However there is a disagreement over its incidence and the aetiological role played by phenothiazine drugs. Kline (1968) in a recent review found a total of 114 cases of ‘irreversible’ oral dyskinesia and concluded that the incidence had been misrepresented since less than two dozen of these recorded cases were previously non-brain damage.
The Modernity of Tradition: Political Development in India

Stressing the variations in meaning of modernity and tradition, this work shows how in India traditional structures and norms have been adapted or transformed to serve the needs of a modernizing society. The persistence of traditional features within modernity, it suggests, answers a need of the human condition. Three areas of Indian life are analyzed: social stratification, charismatic leadership, and law. The authors question whether objective historical conditions, such as advanced industrialization, urbanization, or literacy, are requisites for political modernization.
H1N1 influenza: initial chest radiographic findings in helping predict patient outcome.

PURPOSE To retrospectively evaluate whether findings on initial chest radiographs of influenza A (H1N1) patients can help predict clinical outcome. MATERIALS AND METHODS Institutional review board approval was obtained; informed consent was waived. All adult patients admitted to the emergency department (May to September 2009) with a confirmed diagnosis of H1N1 influenza who underwent frontal chest radiography within 24 hours were included. Radiologic findings were characterized by type and pattern of opacities and zonal distribution. Major adverse outcome measures were mechanical ventilation and death. RESULTS Of 179 H1N1 influenza patients, 97 (54%) underwent chest radiography at admission; 39 (40%) of these had abnormal radiologic findings likely related to influenza infection and five (13%) of these 39 had adverse outcomes. Fifty-eight (60%) of 97 patients had normal radiographs; two (3%) of these had adverse outcomes (P = .113). Characteristic imaging findings included the following: ground-glass (69%), consolidation (59%), frequently patchy (41%), and nodular (28%) opacities. Bilateral opacities were common (62%), with involvement of multiple lung zones (72%). Findings in four or more zones and bilateral peripheral distribution occurred with significantly higher frequency in patients with adverse outcomes compared with patients with good outcomes (multizonal opacities: 60% vs 6%, P = .01; bilateral peripheral opacities: 60% vs 15%, P = .049). CONCLUSION Extensive involvement of both lungs, evidenced by the presence of multizonal and bilateral peripheral opacities, is associated with adverse prognosis. Initial chest radiography may have significance in helping predict clinical outcome but normal initial radiographs cannot exclude adverse outcome.
Negative affect prior to and following overeating-only, loss of control eating-only, and binge eating episodes in obese adults.

OBJECTIVE The objective was to examine the trajectory of five types of negative affect (global negative affect, fear, guilt, hostility, sadness) prior to and following three types of eating episodes (overeating in the absence of loss of control [OE-only], loss of control eating in the absence of overeating [LOC-only], and binge eating) among obese adults using ecological momentary assessment (EMA). METHOD Fifty obese adults (84% female) completed a two-week EMA protocol during which they were asked to record all eating episodes and rate each episode on continua of overeating and loss of control. Momentary measures of global negative affect, fear, guilt, hostility, and sadness were assessed using an abbreviated version of the Positive and Negative Affect Schedule (PANAS). Trajectories for each of the five types of negative affect were modeled prior to and following episodes of OE-only, LOC-only, and binge eating. RESULTS Consistent with previous findings, global negative affect and Guilt increased prior to and decreased following binge eating episodes (all ps < .05). Guilt also decreased following OE-only episodes (p < .05). DISCUSSION These results are consistent with the affect regulation model of binge eating and suggest that binge eating may function to regulate global negative affect, and more specifically, guilt among obese adults. These data suggest that the relationship between negative affect and binge eating may not be unique to individuals with clinical eating disorders and indicate that targeting negative affect may be an effective strategy for the treatment of binge eating in the context of obesity.
Gallium nitride materials - progress, status, and potential roadblocks

Metal-organic vapor phase epitaxy (MOVPE) and molecular beam epitaxy (MBE) are the principal techniques for the growth and n-type (Si) and p-type (Mg) doping of III-nitride thin films on sapphire and silicon carbide substrates as well as previously grown GaN films. Lateral and pendeoepitaxy via MOVPE reduce significantly the dislocation density and residual strain in GaN and AlGaN films. However tilt and coalescence boundaries are produced in the laterally growing material. Very high electron mobilities in the nitrides have been realized in radio-frequency plasma-assisted MBE GaN films and in two-dimensional electron gases in the AlGaN/GaN system grown on MOVPE-derived GaN substrates at the crossover from the intermediate growth regime to the droplet regime. State-of-the-art Mg doping profiles and transport properties have been achieved in MBE-derived p-type GaN. The Mg-memory effect, and heterogeneous growth, substrate uniformity, and flux control are significant challenges for MOVPE and MBE, respectively. Photoluminescence (PL) of MOVPE-derived unintentionally doped (UID) heteroepitaxial GaN films show sharp lines near 3.478 eV due to recombination processes associated with the annihilation of free-excitons (FEs) and excitons bound to a neutral shallow donor (D/spl deg/X).
Price of Anarchy in Non-Cooperative Load Balancing

We investigate the price of anarchy of a load balancing game with $K$ dispatchers. The service rates and holding costs are assumed to depend on the server, and the service discipline is assumed to be processor-sharing at each server. The performance criterion is taken to be the weighted mean number of jobs in the system, or equivalently, the weighted mean sojourn time in the system. For this game, we first show that, for a fixed amount of total incoming traffic, the worst-case Nash equilibrium occurs when each player routes exactly the same amount of traffic, i.e., when the game is symmetric. For this symmetric game, we provide the expression for the loads on the servers at the Nash equilibrium. Using this result we then show that, for a system with two or more servers, the price of anarchy, which is the worst-case ratio of the global cost of the Nash equilibrium to the global cost of the centralized setting, is lower bounded by $K/(2\sqrt{K}-1)$ and upper bounded by $\sqrt{K}$, independently of the number of servers.
