Collaborative music interaction on tabletops: An HCI approach

With the advent of tabletop interaction, collaborative activities are better supported than they are on single-user PCs because there exists a physical shareable space, and interaction with digital data is more embodied and social. In sound and music computing, collaborative music making has traditionally been done using interconnected networks, but using separated computers. Musical tabletops introduce opportunities of playing in collaboration through sharing physically the same musical interface. However, few tabletop musical interfaces exploit this collaborative potential (e.g. the Reactable). We are interested in looking into how collaboration can be fully supported by means of musical tabletops for music performance in contrast with more traditional settings. We are also looking at whether collective musical engagement can be enhanced by providing more suitable interfaces to collaboration. In HCI and software development, we find an iterative process approach of design and evaluation—where evaluation allows us to identify key issues that can be addressed in the next design iteration of the system. Using a similar iterative approach, we plan to design and evaluate some tabletop musical interfaces. The aim is to understand what design choices can enhance and enrich collaboration and collective musical engagement on these systems. In this paper, we explain the evaluation methodologies we have undertaken in three preliminary pilot studies, and the lessons we have learned. Initial findings indicate that evaluating tabletop musical interfaces is a complex endeavour which requires an approach as close as possible to a real context, with an interdisciplinary approach provided by interaction analysis techniques.
Organizational Assimilation: A Multidimensional Reconceptualization and Measure

The authors offer a multidimensional reconceptualization of organizational assimilation developed from a reexamination of the Organizational Assimilation Index (OAI). Using a sample of 656 employees in the United States, the OAI was extended to include a seventh factor and used to detect group differences between men and women, managers and nonmanagers, and members with lengthy and short organizational tenure. Evidence for construct validity was found in relationships between the OAI factors and related variables. Results demonstrate the utility of conceptualizing assimilation as a set of interrelated processes that fluctuate based on various characteristics of organizational membership. The authors discuss implications for assimilation research and offer directions for future scholarship in the area.
Heritability of NEO PI-R Extraversion Facets and Their Relationship With IQ

Abstract In recent years, there has been a renewed interest in the relationship between intelligence and personality. Extraversion, in particular, has been suggested to influence intelligence, but the direction of this relationship has been controversial (Wolf & Ackerman, 2005). In a young adult sample, the NEO PI-R was completed by 103 pairs of monozygotic twins, 181 pairs of dizygotic twins and 210 of their nontwin siblings. IQ data (Multidimensional Aptitude Battery) were available for approximately three quarters of this sample, and were collected at 16 years as part of an ongoing study of cognition conducted by the Queensland Institute of Medical Research. All extraversion facets were significantly influenced by genes with both additive and nonadditive genetic effects being important (heritabilities ranged from .25 for activity to .54 for warmth). While a significant correlation between the extraversion domain score and IQ was not found, the extraversion facet of excitement-seeking (E5) was significantly negatively correlated with both verbal (r = −.15) and performance (r = −.11) IQ scores. The facet of gregariousness was significantly correlated with verbal IQ only (r = −.09). The relationship between excitement-seeking and IQ was further shown to be solely due to additive genetic influences. These common genetic effects may stem from a dependence on brain dopamine, a neurotransmitter that has been implicated in both personality and cognition.
Realized Volatility and Variance: Options via Swaps

Let St denote the value of a stock or stock index at time t. Given a variance/volatility option to be priced and hedged, let us designate as time 0 the start of its averaging period, and time T the end. For t ∈ [0, T ], and τ ≤ t, let R2 τ,t denote the realized variance of returns over the time interval [τ, t]. The mathematical results about the synthesis of volatility and variance swaps will hold exactly if R2 refers to the continuously-monitored variance.

For Love Not Money: Insights on the Career Choice of Early-career Agricultural Scientists

There is concern about the declining number and quality of people entering careers in agricultural science, a situation which may reduce the human capacity to support agricultural industries in the future. The perceptions and experiences of some early career agricultural scientists may provide some insights into how the appeal of a career in agricultural science might be improved. We surveyed 24 early-career agricultural scientists to investigate why they chose to study agricultural science, and their perceptions of the advantages and disadvantages of that choice. Four main reasons for pursuing a career in agricultural science were given by respondents: a connection with agriculture (80%); an interest in science and learning (68%); the real-world applications of job possibilities (35%); and lifestyle benefits (30%). The main disadvantages were perceived to be: low pay (64%); the lack of continuity in the career path (50%); and tenure or job security (36%). The main advantages of the career choice included job satisfaction and flexibility, personal satisfaction, diversity of work opportunities, and an agreeable lifestyle. This research indicates that people working in agriculture generally chose to do so for personal satisfaction rather than remuneration. However, the results do raise issues of job security and continuity, which may deter some from either entering or continuing a career in agricultural science. Improving the appeal of agricultural science as a career seems to depend on creating greater awareness among rural school leavers and their advisors about what agricultural science involves as a profession. Moreover, providing greater continuity and clarity of career path is also likely to contribute to its appeal. Universities, professional organisations, and research and development agencies all have a stake in helping to achieve this.
Influence of the Irradiance on Carbohydrate Content and Rooting of Cuttings of Pine Seedlings (Pinus sylvestris L.).

Seedlings of Pinus sylvestris L. were grown for 6 weeks at an irradiance of either 8 or 40 watts per square meter in a controlled environment room. Cuttings from these plants were rooted in tap water for 75 days at either 8 or 40 watts per square meter. The photoperiod was 17 hours.During the first 30 days of the rooting period quantitative changes in carbohydrates were recorded in cuttings from the different treatments. The carbohydrate contents of the cuttings were mainly regulated by the irradiance during the stock plant stage and generally a higher carbohydrate level was found in cuttings from stock plants grown at 40 watts per square meter.The irradiance during the rooting period had only minor effects on the time course of root formation, whereas the irradiance during the stock plant stage did influence the subsequent root formation. Cuttings from stock plants grown at 8 watts per square meter rooted faster and with higher frequency than those from stock plants grown at 40 watts per square meter. These results are discussed in relation to the mentioned irradiance effects on carbohydrate content.
IS THERE A LINK BETWEEN CREATIVITY AND SCHOOL GRADES: RESEARCH WITH 9TH GRADE STUDENTS

Background and Purpose . The present study aimed to explore the relationship between creativity and school grades. Material and Methods. Creativity was meas- ured by the Test for Creative Thinking – Drawing Production (TCT-DP) (Urban & Jellen, 2010). The participants (sample) consisted of 180 ninth grade students (104 females) with mean age of 15.1 years. Results. Both boys and girls with higher creative potential score in TCT-DP showed higher average school grade. The tendency was depicted that school grades in the subjects of natural sciences (except in geography) and arts relate most closely to creativity. Although no significant gender differences were found in any of the subjects, boys tended to show higher correlations. The general trend in the relationship between separate TCT-DP criteria and school grades is that the ability to draw a picture with strong expressive power, to make additions to the used elements, to compose a theme or gestalt of the given elements and to break away from two- dimensionality is significantly related to the average school grade independently of the gender. Conclusion. The results give grounds for further exploration of students’ creativity in relation to the academic performance assessed by teachers.
The Investment Opportunity Set and its Proxy Variables

We use a real options approach to evaluate the performance of several proxy variables for a firm's investment opportunity set. The results show that, on a relative scale, the market-to-book assets ratio has the highest information content with respect to investment opportunities. Although both the market-to-book equity and the earnings-price ratios are related to investment opportunities, they do not contain information that is not already contained in the market-to-book assets ratio. Consistent with this finding, a common factor constructed from several proxy variables does not improve the performance of the market-to-book assets ratio. 2008 The Southern Finance Association and the Southwestern Finance Association.

Long-term Predictors and Consequences of Optimal Psychological Outcomes in Childhood Cancer Survivors

The goal of this dissertation is to examine predictors and consequences of optimal psychological outcomes in childhood cancer survivors. This goal was pursued according to the following three specific aims: 1) to test whether posttraumatic growth (PTG) is distinct from life satisfaction, 2) to examine predictors of PTG and life satisfaction in adolescence, and 3) to assess effects of PTG and life satisfaction in adolescence on future psychological and health functioning later in emerging adulthood. A sample of 2802 childhood cancer survivors from the largest dataset of childhood cancer survivors lead by St Jude Research Hospital was followed for more than 10 years at three different time points: 1996, 2003, and 2007. Confirmatory Factor Analyses were performed to identify the relationship between PTG and life satisfaction while Structural Regression Modeling was performed to identify the predictors and outcomes of PTG and life satisfaction. Results of the study showed that PTG and life satisfaction were slightly correlated but formed distinct constructs. The significant predictors from adolescence of high amount of PTG were older age at diagnosis, having medical issues, facing recurrence of cancer, and being diagnosed with blood cancer. In addition, higher PTG forecasted lower health perception in 2007. However, all the effects were small. The significant predictors from adolescence of higher life satisfaction were lower mental health issues, lower medical issues, higher social skills, and blood cancer as a type of cancer diagnosis. Higher life satisfaction forecasted lower mental health issues, higher health perception, lower pain, and lower somatization. Therefore, this study brought more insight on the long-term effects of PTG and life satisfaction for childhood cancer survivors. In particular, these findings showed that being satisfied with life could help childhood cancer survivors to have less psychological issues and a better perception of health in the future. These relationships can provide guidance to mental health practitioners for therapies focusing on improving life satisfaction as a way to decrease anxiety, depression, somatization, and pain of childhood cancer survivors.
Mapping B-Cell Epitopes of Hepatitis C Virus E2 Glycoprotein Using Human Monoclonal Antibodies from Phage Display Libraries

ABSTRACT Clinical and experimental evidence indicates that the hepatitis C virus (HCV) E2 glycoprotein (HCV/E2) is the most promising candidate for the development of an effective anti-HCV vaccine. Identification of the human epitopes that are conserved among isolates and are able to elicit protective antibodies would constitute a significant step forward. This work describes the mapping of the B-cell epitopes present on the surface of HCV/E2, as recognized by the immune system during infection, by the analysis of the reciprocal interactions of a panel of human recombinant Fabs derived from an HCV-infected patient. Three unrelated epitopes recognized by antibodies with no neutralization-of-binding (NOB) activity were identified; a fourth, major epitope was defined as a clustering of minor epitopes recognized by Fabs endowed with strong NOB activity.
Blood Stream Infections in Patients in the Burn Intensive Care Unit

Background The study on bacteremia helps empirically select the proper antibiotics before the results of culture test about causative pathogen. The purpose of this study is to investigate causative pathogen in bloodstream infection, changing aspects based on elapsed time after burn, relationship with other sites and resistance of important causative pathogen against antibiotics through analysis on bacteria isolated from blood culture of patients hospitalized in burn intensive care unit (BICU). Materials and Methods A retrospective study was conducted targeting patients hospitalized in BICU from January 2007 to June 2011. Changes of causative pathogen in bloodstream infection based on elapsed time after injury were analyzed. We would like to examine the relationship between bloodstream infection and infection on other body parts by comparing results of cultures in burn wound site, sputum, urine and catheter tip. Antibiotics resistance patterns of Pseudomonas aeruginosa, Acinetobacter baumannii, Staphylococcus aureus, Enterococcus species, and Klebsiella pneumoniae were studied. Results A total of 2,337 burn patients were hospitalized in BICU for 54 months. Causative pathogen was cultured in blood cultures from 397 patients (17.0%). P. aeruginosa (169, 30.1%) was the most cultured and A. baumannii (107, 19.0%) and S. aureus (81, 14.4%) were followed. It was confirmed that the relative frequency of A. baumannii tended to get lower as the period got longer after injury, but the relative frequency of K. pneumoniae got higher as the period got longer after injury. With comparison without bacteremia, P. aeruginosa bacteremia showed high probability in which the same bacteria were cultured in wound site, sputum and cathether tip, and A. baumannii bacteremia and candida bacteremia had high probability in sputum, and urine and catheter tip, respectively. 95.9% of P. aeruginosa and 95.3% of A. baumannii showed the resistance against carbapenem. 96.3% of S. aureus was methicillin resistant and 36.2% of Enterococcus species were vancomycin resistant. 75.0% of K. pneumonia were extended-spectrum beta-lactamase (ESBL)-producing bacteria. Conclusions Since the highly antibiotic resistant microorganisms were isolated from the patients hospitalized in BICU during early phase, the empirical selection of antibiotics targeting these pathogens should be considered before the results of microbiologic culture test. In addition, use of empirical antifungal agent after 1 week of injury can be considered for patients who have risk factor of fungal infection.
Context, Capacity, and Concern: A District-Level Analysis of the Implementation of Standards-Based Reform in New York State

Policy makers have initiated a dramatic period of standards-based reform for New York State students, an effort of great relevance across the United States. Although comprehensive high school examinations and state-endorsed Regents diplomas are over 100 years old, the demand that all students must earn college-preparatory diplomas is new. This research asked under what conditions district context matters in implementing of standards-based reform. The authors posited that personnel (teachers, principals, and superintendents) interact with the contextual characteristics of their district environments (organizational size, geography, resources, personnel level) in ways that shape responses to standards-based reforms. Surveys and state-collected data, along with multilevel modeling, were used to weigh programmatic reform at the school district level. Districts serving greater proportions of poor students were more likely to offer general equivalency diploma alternatives to the Regents diploma. Whether these phenomena undermine the heightened standards for all children or reflect healthy local variation and choice is debatable.
Predicting Forced Population Displacement Using News Articles

The world has witnessed mass forced population displacement across the globe. Population displacement has various indications, with different social and policy consequences. Mitigation of the humanitarian crisis requires tracking and predicting the population movements to allocate the necessary resources and inform the policymakers. The set of events that triggers population movements can be traced in the news articles. In this paper, we propose the Population Displacement-Signal Extraction Framework (PD-SEF) to explore a large news corpus and extract the signals of forced population displacement. PD-SEF measures and evaluates violence signals, which is a critical factor of forced displacement from it. Following signal extraction, we propose a displacement prediction model based on extracted violence scores. Experimental results indicate the effectiveness of our framework in extracting high quality violence scores and building accurate prediction models.
Postexposure Prophylaxis against Anthrax: Evaluation of Various Treatment Regimens in Intranasally Infected Guinea Pigs

ABSTRACT The efficiency of postexposure prophylaxis against Bacillus anthracis infection was tested in guinea pigs infected intranasally with either Vollum or strain ATCC 6605 spores (75 times the 50% lethal dose [LD50] and 87 times LD50, respectively). Starting 24 h postinfection, animals were treated three times per day for 14 days with ciprofloxacin, tetracycline, erythromycin, cefazolin, and trimethoprim-sulfamethoxazole (TMP-SMX). Administration of cefazolin and TMP-SMX failed to protect the animals, while ciprofloxacin, tetracycline, and erythromycin prevented death. Upon cessation of treatment all erythromycin-treated animals died; of the tetracycline-treated animals, two of eight infected with Vollum and one of nine infected with ATCC 6605 survived; and of the ciprofloxacin group injected with either 10 or 20 mg/kg of body weight, five of nine and five of five animals, respectively, survived. To test the added value of extending the treatment period, Vollum-infected (46 times the LD50) animals were treated for 30 days with ciprofloxacin or tetracycline, resulting in protection of eight of nine and nine of nine animals, respectively. Once treatment was discontinued, only four of eight and five of nine animals, respectively, survived. Following rechallenge (intramuscularly) of the survivors with 30 times the LD50 of Vollum spores, all ciprofloxacin-treated animals were protected while none of the tetracycline-treated animals survived. In an attempt to confer protective immunity lasting beyond the termination of antibiotic administration, Vollum-infected animals were immunized with a protective antigen (PA)-based vaccine concurrently with treatment with either ciprofloxacin or tetracycline. The combined treatment protected eight of eight and nine of nine animals. Following cessation of antibiotic administration seven of eight and eight of eight animals survived, of which six of seven and eight of eight resisted rechallenge. These results indicate that a combined treatment of antibiotics together with a PA-based vaccine could provide long-term protection to prevent reoccurrence of anthrax disease.
A Census of Outdoor Orientation Programs at Four-Year Colleges in the United States

Researchers surveyed colleges and universities in the United States to assess the number providing outdoor orientation programs (OOPs). OOPs are defined as college orientation programs that work with small groups (15 or fewer) of first-year students, use adventure experiences, and include at least one overnight in a wilderness setting. This census identified and received survey data from 164 separate OOPs, representing at least 97% of all programs. From the data, researchers ascertained common peer practices describing the current state of OOPs. Although programs differed significantly by age and by size, programs generally shared common practices. With the number of OOPs growing—an average of 10 new OOPs begin each year—the current census was designed to better understand how OOPs operate and how they may be changing.
Socio‐economic determinants of HIV testing and counselling: a comparative study in four African countries

Research indicates that individuals tested for HIV have higher socio‐economic status than those not tested, but less is known about how socio‐economic status is associated with modes of testing. We compared individuals tested through provider‐initiated testing and counselling (PITC), those tested through voluntary counselling and testing (VCT) and those never tested.
Lacanian theory's contribution to the study of workplace envy

In this article, we wish to develop further the reflection undertaken by the few authors who have started using Lacan's theories in their research on organizations. We suggest that using a framework based on Lacanian theory can help us better understand workplace envy, which is such a complex emotion, and better integrate the existing studies on organizational envy. Our analysis is based on a clinical case study. Whereas Kleinian theory sees envy as involving two subjects, Lacanian theory approaches envy as a triangular relationship between an envied subject and a quasi similar envious person, watched (approvingly/disapprovingly) by a `big Other'. This theory helps understand that envy and narcissism are related and that they originate at the stage in psychic development that Lacan calls the `mirror stage'. Whereas the Kleinian approach highlights the differences between the Envious and the Envied and the position of dependence of one on the other, Lacanian theory outlines the role of the `double', the symmetrical position of the Envied and the Envious, and the alienation to the Other. The Lacanian approach also enables us to consider interventions in contexts where envy is present.
