Team creativity versus team learning: transcending conceptual boundaries to inspire future framework building

The purpose of this study was to compare team creativity and team learning – approached as interpersonal processes – conceptually and empirically and thereby inspire future framework building on team creativity. First, both concepts were compared based on present literature. In the next – empirical – step, a questionnaire consisting of a range of team creative and learning processes was developed and validated among 112 design teams, encompassing 540 employees. By means of a questionnaire validation protocol, this study assessed the empirical similarities and interrelation between team creative and learning processes. Several conceptual similarities in both frameworks were identified. The theoretically expected difference between team creativity and team learning (i.e. the aspect newness) was not supported by our empirical results. A five-factor model – consisting of team creative efficacy, facilitating team processes, basic team processes, error communication, and co-construction was validated. This study contributes to the present literature by showing that future theorising on team creative processes can certainly draw inspiration from the team learning literature in several ways.
Exploring implicit ingroup and outgroup bias toward Hispanics

Racial and ethnic biases often manifest without awareness. The underlying causes of these attitudes are not fully understood. While outgroup bias is well studied, ingroup bias has received far less attention. We examined ingroup biases among Hispanic women and outgroup biases toward Hispanics among White (Caucasian non-Hispanic) females using the startle eyeblink paradigm, the Implicit Association Test (IAT), and an explicit self-report measure. Hispanic and White male faces were used as exemplars during both the startle task and the IAT. A similar pattern of results were observed for indirect measures: both groups displayed startle and IAT responses indicative of negative attitudes toward Hispanic male faces relative to White male faces, although less so for Hispanic participants. Combined groups correlational analyses revealed a significant positive relationship between startle eyeblink amplitude and subtle subscale bias scores. However, no relationships were found between any measures when groups were examined separately. The comparable pattern of startle and IAT results suggests that in spite of the likelihood that these measures index different aspects of attitudes and tap into different processes, inter and intragroup biases are manifested similarly. The finding of negative ingroup biases among Hispanic females is consistent with system justification theory, which posits that members of devalued groups internalize negative stereotypes about their ingroup. This study extends startle eyeblink research of intergroup racial biases, while also expanding this line of research to intragroup biases. In doing so, these results add to our knowledge of the mechanisms underlying the persistent nature of stereotypes.
Evaluation of remote sensing based terrestrial productivity from MODIS using regional tower eddy flux network observations

The Moderate Resolution Spectroradiometer (MODIS) sensor has provided near real-time estimates of gross primary production (GPP) since March 2000. We compare four years (2000 to 2003) of satellite-based calculations of GPP with tower eddy CO2 flux-based estimates across diverse land cover types and climate regimes. We examine the potential error contributions from meteorology, leaf area index (LAI)/fPAR, and land cover. The error between annual GPP computed from NASA's Data Assimilation Office's (DAO) and tower-based meteorology is 28%, indicating that NASA's DAO global meteorology plays an important role in the accuracy of the GPP algorithm. Approximately 62% of MOD15-based estimates of LAI were within the estimates based on field optical measurements, although remaining values overestimated site values. Land cover presented the fewest errors, with most errors within the forest classes, reducing potential error. Tower-based and MODIS estimates of annual GPP compare favorably for most biomes, although MODIS GPP overestimates tower-based calculations by 20%-30%. Seasonally, summer estimates of MODIS GPP are closest to tower data, and spring estimates are the worst, most likely the result of the relatively rapid onset of leaf-out. The results of this study indicate, however, that the current MODIS GPP algorithm shows reasonable spatial patterns and temporal variability across a diverse range of biomes and climate regimes. So, while continued efforts are needed to isolate particular problems in specific biomes, we are optimistic about the general quality of these data, and continuation of the MOD17 GPP product will likely provide a key component of global terrestrial ecosystem analysis, providing continuous weekly measurements of global vegetation production
The Relationship of Personality Traits to Teacher Candidate Perceptions of Teaching Confidence and Teaching Experience in a Simulated Classroom Environment

Individual personality traits of pre-service teachers may have a significant influence on their confidence in teaching. Confidence in teaching does not always align with the experience of pre-service teachers. simSchool enables transformational experiences for teacher candidates to improve in general teaching skills, connect learning theories in the classroom, and develop confidence to be an effective teacher without the ill impacts of practicing on real students. This study executed a quasi-experimental design to explore the personality traits of 152 pre-service teachers and examined how their perceptions of teaching confidence and teaching experience were related in the context of simSchool. A treatment and comparison group completed the Survey of Teaching Skills pre/post tests and the OCEAN survey for quantitative data analysis to investigate four research questions: 1. Is there a difference between treatment and comparison groups on educator’s gains in confidence and experience? 2. Is there a relationship between personality type and perceived teaching effectiveness? 3. Is there a relationship between personality attributes and pre-service educator ratings of teaching experience in a simulated teaching environment? 4. Is there a relationship between personality attributes and pre-service educator ratings of teaching confidence in a simulated teaching environment? Findings from repeated measures MANOVA tests indicated that the simSchool treatment group increased their perceptions of experience with significant gains (p < .05), in contrast to the comparison group. Two key constructs of personality and effective teaching, the latter of which is comprised of the pre-service teachers’ self-reports of teaching confidence and teaching experience, were examined using canonical correlation analysis. The traits of openness, conscientiousness, extraversion, agreeableness and neuroticism were components linked by structure coefficients to the synthetic variable of personality, the latter of which was found to be correlated with effective teaching. Pearson product-moment correlation coefficients were produced to assess the relationship between experience and confidence and relationships between experience and confidence with the personality traits of conscientiousness, openness, extraversion, and emotional stability. Multiple regression analyses were run using the predictors of openness, conscientiousness, extraversion, and neuroticism. These were found to be significantly (p < .05) effective in predicting self-reported teaching experience and confidence from personality traits. Furthermore, the variable of openness was individually found to be a significant (p < .05) predictor of teaching experience and confidence. These findings suggest that personality traits affect the experience and confidence ratings of pre-service teachers in a simulated classroom environment and that simSchool training can foster the development of teaching effectiveness.

Interactions of Attenuated Mycobacterium tuberculosis phoP Mutant with Human Macrophages

Background Mycobacterium tuberculosis phoP mutant SO2 derived from a clinical isolate was shown to be attenuated in mouse bone marrow-derived macrophages and in vivo mouse infection model and has demonstrated a high potential as attenuated vaccine candidate against tuberculosis. Methodology/Principal Findings In this study, we analyze the adhesion and the intracellular growth and trafficking of SO2 in human macrophages. Our results indicate an enhanced adhesion to phagocitic cells and impaired intracellular replication of SO2 in both monocyte-derived macrophages and human cell line THP-1 in comparison with the wild type strain, consistent with murine model. Intracellular trafficking analysis in human THP-1 cells suggest that attenuation of SO2 within macrophages could be due to an impaired ability to block phagosome-lysosome fusion compared with the parental M. tuberculosis strain. No differences were found between SO2 and the wild-type strains in the release and mycobacterial susceptibility to nitric oxide (NO) produced by infected macrophages. Conclusions/Significance SO2 has enhanced ability to bind human macrophages and differs in intracellular trafficking as to wild-type M. tuberculosis. The altered lipid profile expression of the phoP mutant SO2 and its inability to secrete ESAT-6 is discussed.
Social Contact Structures and Time Use Patterns in the Manicaland Province of Zimbabwe

Background Patterns of person-to-person contacts relevant for infectious diseases transmission are still poorly quantified in Sub-Saharan Africa (SSA), where socio-demographic structures and behavioral attitudes are expected to be different from those of more developed countries. Methods and Findings We conducted a diary-based survey on daily contacts and time-use of individuals of different ages in one rural and one peri-urban site of Manicaland, Zimbabwe. A total of 2,490 diaries were collected and used to derive age-structured contact matrices, to analyze time spent by individuals in different settings, and to identify the key determinants of individuals’ mixing patterns. Overall 10.8 contacts per person/day were reported, with a significant difference between the peri-urban and the rural site (11.6 versus 10.2). A strong age-assortativeness characterized contacts of school-aged children, whereas the high proportion of extended families and the young population age-structure led to a significant intergenerational mixing at older ages. Individuals spent on average 67% of daytime at home, 2% at work, and 9% at school. Active participation in school and work resulted the key drivers of the number of contacts and, similarly, household size, class size, and time spent at work influenced the number of home, school, and work contacts, respectively. We found that the heterogeneous nature of home contacts is critical for an epidemic transmission chain. In particular, our results suggest that, during the initial phase of an epidemic, about 50% of infections are expected to occur among individuals younger than 12 years and less than 20% among individuals older than 35 years. Conclusions With the current work, we have gathered data and information on the ways through which individuals in SSA interact, and on the factors that mostly facilitate this interaction. Monitoring these processes is critical to realistically predict the effects of interventions on infectious diseases dynamics.
Benefits of perfusion MR imaging relative to diffusion MR imaging in the diagnosis and treatment of hyperacute stroke.

BACKGROUND AND PURPOSE The development of thrombolytic agents for use with compromised cerebral blood flow has made it critical to quickly identify those patients to best treat. We hypothesized that combined diffusion and perfusion MR imaging adds vital diagnostic value for patients for whom the greatest potential benefits exist and far exceeds the diagnostic value of diffusion MR imaging alone. METHODS The cases of patients with neurologic symptoms of acute ischemic stroke who underwent ultra-fast emergent MR imaging within 6 hours were reviewed. In all cases, automatic processing yielded isotropic diffusion images and perfusion time-to-peak maps. Images with large vessel distribution ischemia and with mismatched perfusion abnormalities were correlated with patient records. All follow-up images were reviewed and compared with outcomes resulting from hyperacute therapies. RESULTS For 16 (26%) of 62 patients, hypoperfusion was the best MR imaging evidence of disease distribution, and for 15 of the 16, hypoperfusion (not abnormal diffusion) comprised the only imaging evidence for disease involving large vessels. For seven patients, diffusion imaging findings were entirely normal, and for nine, diffusion imaging delineated abnormal signal in either small vessel distributions or in a notably smaller cortical branch in one case. In all cases, perfusion maps were predictive of eventual lesions, as confirmed by angiography, CT, or subsequent MR imaging. CONCLUSION If only diffusion MR imaging is used in assessing patients with hyperacute stroke, nearly one quarter of the cases may be incorrectly categorized with respect to the distribution of ischemic at-risk tissue. Addition of perfusion information further enables better categorizing of vascular distribution to allow the best selection among therapeutic options and to improve patient outcomes.
Correlation between depressive symptoms and subjective mastication ability and ability to pronunciation among Korean elderly

OBJECTIVES The present study examines the relationship between depressive symptoms and subjective chewing and pronunciation ability in Korean seniors. Our goal is to provide the data required to develop appropriate oral health interventions programs for seniors. METHODS The Center for Epidemiologic Studies-Depression Scale (CES-D) is widely used depressive symptoms assessment. A Korean version was used for the 2009 Community Health Survey, which was consulted to extract the present study’s participants comprising 50,694 Korean seniors (males, 20,582; females, 30,112) aged ≥65 years. Those with a CES-D score ≥16 were rated ‘depressed. ’ SAS version 9.3 was used for the data analysis. RESULTS Prevalence of depressive symptoms increased as the participants socioeconomic status decreased, number of health issues increased, health behavior worsened, and chewing and pronunciation discomfort increased. Males with chewing difficulties were found to have 1.45 times (95% confidence interval [CI], 1.29 to 1.63) greater risk of depressive symptoms than those without, while males with pronunciation discomfort were found to have 1.97 times greater risk of depressive symptoms than those without (95% CI, 1.76 to 2.20). Females with chewing difficulty were found to have 1.50 times (95% CI, 1.39 to 1.61) greater risk of depressive symptoms than those without, and females with pronunciation discomfort were found to have 1.55 times greater risk of depressive symptoms than those without (95% CI, 1.44 to 1.67). CONCLUSIONS Intervention programs designed to help with oral health management and alleviate depressive symptoms in seniors are urgently needed. As the prevalence of depressive symptoms may vary geographically, research examining potential variance at city, district, and town levels would be beneficial.
Protective effects of insulin-like growth factor-I on the decrease in myogenic differentiation by ionizing radiation

Purpose: The aim of the work is to evaluate the effects of insulin-like growth factor-1 (IGF-1) on the decrease in myotube formation induced by ionizing radiation. Materials and methods: We induced C2C12 cells to a myogenic linage following X-ray irradiation at 2 and 4 Gy. Myogenic differentiation was estimated using immnocytochemical staining with anti-myosin antibody, and the anti-myosin antibody positive areas, the total number of nuclei, the number of nuclei included in multinucleated myotubes per field, and the myotube formation ratio were analyzed. Results: In the myogenic differentiation in the presence of IGF-1, the decrease in anti-myosin antibody positive areas, the nuclei included in myotubes, and the myotube formation ratio induced by X-ray irradiation at 2 Gy was restored to control levels. Conclusions: The addition of IGF-1 protected against the decrease myotube formation induced by X-ray irradiation at 2 Gy. Since X-ray irradiation at 2 Gy is usually used for multi-fractionated irradiation in radiotherapy, our findings suggest that IGF-1 could be useful to protect against impairment of muscle repair induced by therapeutic dose radiation.
DISSOCIATION CONSTANTS OF SOME COMPOUNDS RELATED TO LYSERGIC ACID; (β‐Dimethylaminopropionic Acid, Dihydroarecaidine, Ecgonine and their Derivatives

IT has been shown' that the dissociation constants of the dihydrolysergic acids are in agreement with the view that those dihydrolysergic acids in which the C,,, carboxyl is remote (equatorial) from N,,, are weaker bases than those in which the C,,, carboxyl is axial. Because of the small amount of material available it was necessary to measure these dissociation constants by the method of Craig, Shedlovsky, Gould and Jacobs,2 in which the pH value of a solution half neutralised by the addition of the calculated amount of carbonate-free sodium hydroxide was recorded. Since this method is open to certain objections, the experimental work now described was undertaken to confirm the above conclusions by potentiometric determination of dissociation constants of analagous, but more readily available materials of known structure. Whilst this work was in progress, Stoll, Petrzilka, Rutschmann, Hofmann and Gunthard3 have published dissociation constants for the dihydrolysergic and dihydronorlysergic acids, and other evidence which further substantiates our conclusions. EXPERIMENTAL Titrations were carried out in a specially constructed micro-cell thermostatically controlled at 25" C. , using a Doran alk-acid glass electrode in conjunction with a Cambridge Direct ReadingpH meter. An Agla micrometer syringe was used as a burette. Carbon dioxide-free nitrogen was bubbled through the solution, which was stirred by means of a magnetic stirrer. Solutions of 0.02 millimoles of the hydrochlorides or hydrobromides of the pure substances in carbon dioxide-free double-distilled water were titrated potentiometrically with 0.05N carbonate-free potassium hydroxide, the volume of solvent being calculated to yield a 0.005M solution at half-neutrality. The potassium hydroxide solution was obtained by the method of Steinbach and FreiserY4 in which 0.05M potassium chloride solution is passed through a column of ion exchange resin IRA 400. The eluant standard alkali was fed directly to the micrometer syringe. An experimentally determined correction for solvent effect was applied, based on the methods of Tague5 and Harris6 in the following way. A blank titration was carried out under the same conditions used in the test, whereby the material under test was replaced by an equivalent quantity of carbon dioxide-free hydrochloric acid. The volumes of 0.05N potassium hydroxide solution required to raise the pH value in the blank determination from 7.0 to various pre-selected values were determined accurately from a mean of eight titrations. From this it was possible to
The Attraction Effect in Decision Making: Superior Performance by Older Adults

Previous work showed that older adults' choice performance can be wiser than that of younger adults (Tentori, Osherson, Hasher, & May, 2001). We contrasted two possible interpretations: a general expertise/wisdom view that suggests that older adults are generally more skilled at making decisions than younger adults and a domain-specific expertise view that suggests that older adults are more skilled decision makers only in domains in which they have greater knowledge. These hypotheses were contrasted using attraction effect tasks in two different domains: earning extra credit in a course and grocery shopping, domains presumed to be of different levels of knowledge to younger and older adults. Older adults showed consistent choice for both domains; younger adults showed consistent choice only for the extra credit problem. Several explanations of these findings are considered, including Damasio's somatic marker theory and age differences in reliance on heuristic versus analytic styles.
The Impact of Postmeningitic Labyrinthitis Ossificans on Speech Performance After Pediatric Cochlear Implantation

Objective: 1) To characterize pediatric cochlear implant performance in patients with hearing loss secondary to bacterial meningitis. 2) To evaluate performance differences in patients with and without labyrinthitis ossificans (LO). Study Design: Retrospective case review. Setting: A large university-based multidisciplinary cochlear implant program. Patients: Forty-nine patients with hearing loss from bacterial meningitis who received cochlear implants from 1991 to 2011. Thirty-nine patients had adequate data for analysis. Intervention: Cochlear implantation with postoperative performance evaluation. Main Outcome Measure(s): Speech perception category (SPC). Results: Nineteen (48.7%) patients had intraoperative evidence of LO. Fourteen patients (70.0%) without LO compared with seven (36.8%) with LO developed open-set speech after implantation. There was a trend toward better postimplant SPC outcomes in patients without LO that did not reach statistical significance (p = 0.17). The presence of LO negatively correlated with classroom placement (p < 0.05). Analysis of each group individually demonstrated statistically significant improvement in pre- versus postimplant SPC outcomes (p < 0.001). Conclusion: The presence of LO may negatively affect performance in pediatric patients receiving a cochlear implant for hearing loss secondary to bacterial meningitis.
Irregular gastrointestinal drug absorption in Parkinson's disease

Background: Symptomatic treatment of Parkinson's disease (PD) is based on the dopamine precursor levodopa. Levodopa is only absorbed in the small intestine, where transit time is ∼ 3 h and the plasma elimination half-life is short. Therefore, gastric emptying is a major determining factor for onset of symptom relief. Objective: Gastric emptying is delayed in PD, thereby causing motor fluctuations such as ‘delayed on’. Factors that further slow gastric emptying should be recognised and eliminated if possible. Methods: A literature search was performed with the aim to cover the area of irregular gastrointestinal drug absorption in PD. Results/conclusion: Methods for facilitation of pyloric passage or increase of bioavailability are discussed. Development of new drug formulations and alternative routes of administration is ongoing. Transdermal patches and pumps for subcutaneous or intraduodenal infusions are available for patients with severe fluctuations due to erratic gastric emptying.
