The impact of team familiarity and team leader experience on team coordination errors: A panel analysis of professional basketball teams

Summary To explore the dynamics involved in team coordination, we examine the impact of team familiarity and team leader experience on team coordination errors (TCEs). We argue that team familiarity has a U-shaped effect on TCEs. We study the moderating effects of team leader prior experience and team leader team-specific experience on the association between team familiarity and TCEs. We use panel data on teams from the National Basketball Association to test the hypotheses. Our findings support the U-shaped relationship between team familiarity and TCEs and the moderating effect of team leader team-specific experience on this relationship. The paper advances research on errors in organizations by analyzing the antecedents of TCEs, so far an underexplored empirical phenomenon. Moreover, it contributes to research on coordination in teams by empirically examining the interplay between formal and informal coordination mechanisms. Copyright © 2015 John Wiley & Sons, Ltd.
Extragenic suppressors of paralyzed flagellar mutations in Chlamydomonas reinhardtii identify loci that alter the inner dynein arms

We have analyzed extragenic suppressors of paralyzed flagella mutations in Chlamydomonas reinhardtii in an effort to identify new dynein mutations. A temperature-sensitive allele of the PF16 locus was mutagenized and then screened for revertants that could swim at the restrictive temperature (Dutcher et al. 1984. J. Cell Biol. 98:229- 236). In backcrosses of one of the revertant strains to wild-type, we recovered both the original pf16 mutation and a second, unlinked suppressor mutation with its own flagellar phenotype. This mutation has been identified by both recombination and complementation tests as a new allele of the previously uncharacterized PF9 locus on linkage group XII/XIII. SDS-PAGE analysis of isolated flagellar axonemes and dynein extracts has demonstrated that the pf9 strains are missing four polypeptides that form the I1 inner arm dynein subunit. The primary effect of the loss of the I1 subunit is a decrease in the forward swimming velocity due to a change in the flagellar waveform. Both the flagellar beat frequency and the axonemal ATPase activity are nearly wild-type. Examination of axonemes by thin section electron microscopy and image averaging methods reveals that a specific domain of the inner arm complex is missing in the pf9 mutant strains (see accompanying paper by Mastronarde et al.). When combined with other flagellar defects, the loss of the I1 subunit has synergistic effects on both flagellar assembly and flagellar motility. These synthetic phenotypes provide a screen for new suppressor mutations in other loci. Using this approach, we have identified the first interactive suppressors of a dynein arm mutation and an unusual bypass suppressor mutation.
Adult Careers: Does Childhood IQ Predict Later Life Outcome?

The author's plenary address at the 3rd International Association for the Scientific Study of Intellectual Disabilities-Europe Conference in Rome, Italy (October 2010), provided a retrospective overview of a longitudinal study conducted with a cohort of pre-teens (11 and 13 years of age) residing in Warsaw, Poland, in the 1970s. The intent was to examine, over an extended period of years, the relationship between social origin and measured intelligence (IQ), the role that IQ and other psycho-social factors play as predictors of social and economic status in adulthood, and the stability of IQ. The question posed by the “Warsaw Studies” was whether, given the virtual absence of educational, health service, and community distinctions (Warsaw in the 1970s was an ideal laboratory for such a sociological undertaking), would Warsaw schoolchildren still show the usual association between parental occupation and offspring intellectual functioning? The results from a series of follow-up studies indicate that the IQ score at age 13 could be viewed as a relatively good indicator for future life outcomes, defined in terms of attained education, occupational status, and material well being. Dramatic differences in this attainment between the groups of respondents with high and low IQ scores attest to this conclusion. Smaller, yet still significant, differences between talented teenagers and their counterparts from the two control groups who apparently did not have the high IQ advantage also support the thesis that IQ matters much for life success. The findings of the “Warsaw Studies” have implications for the life course and economic conditions of children with intellectual disabilities from disadvantaged backgrounds.
A Web-based Approach to Determine the Origin of an Artist

One can define the origin of an artist as the geographical location where he started his career. The origin is an important metadata element, because it can help to specify subgenres, be an indicator of regional popularity and improve recommendations. In this paper, we present six methods to determine the origin, based on Web data sources: one extracts data from Last.fm, two query Freebase and three analyze biographies. We evaluate the different methods with 11275 artists. Circa 55% of the artists can be classified using biographies. The best Freebase method can classify 26% and the Last.fm based method 7%. When comparing on accuracy, the Last.fm and Freebase methods perform similarly with around 90% accuracy. For the biography-based methods we achieve 71%. To improve coverage, a final, hybrid method achieves 77% accuracy and 60% coverage. The accuracy of the continent classification is 87%. As a showcase for our classifier, we developed a mashup application that displays, among others, information about the origin of artists from radio station playlists on a map.
Understanding continuance usage of mobile services

Users' continuance usage is crucial to mobile service providers' success. Integrating both perspectives of flow and switching costs, this research identified the factors affecting continuance usage of mobile services. The results indicate that effort expectancy and ubiquitous connection affect flow, which in turn affects performance expectancy. Switching costs affect switching barrier. Flow, performance expectancy and switching barrier determine continuance usage. The results imply that service providers need to concern both user experience and switching costs in order to retain users and facilitate their continuance usage.
Cheating In Business Schools, The Millennial Generation, Gender And Racial Diversity: Has The Paradigm Shifted

Cheating in college is not new. In 1960 over 50 percent of students admitted they cheated. In the second decade of the 21 st century has anything changed? This research project looked at three possible new variables, the Millennial Generation, Gender, and Diversity. Results suggest the amount of reported cheating remains the same even with current “Gen Yers” in college. There was also no measured difference in cheating between men and women students. Finally, the present study found that Asian-Americans admitted to cheating far more than the average and Latino-Americans reported to have cheated in college far less than the average current students in college. This paper concludes with the following three implications: 1) Current college undergraduates, “the Millennial Generation,” may actually be more ethical as measured in this study than their Boomer Parents. 2) Women and graduates as measured in this study may be more prone to college cheating than women students in the past—trends of a new post-feminist generation? 3) Finally, diversity and the core values embedded in America’s individual subcultures, such as Asian and Hispanic, appear to significantly influence ethical choices of today’s college students—diversity within the melting pot?
Abscisic Acid Promotes Susceptibility to the Rice Leaf Blight Pathogen Xanthomonas oryzae pv oryzae by Suppressing Salicylic Acid-Mediated Defenses

The plant hormone abscisic acid (ABA) is involved in a wide variety of plant processes, including the initiation of stress-adaptive responses to various environmental cues. Recently, ABA also emerged as a central factor in the regulation and integration of plant immune responses, although little is known about the underlying mechanisms. Aiming to advance our understanding of ABA-modulated disease resistance, we have analyzed the impact, dynamics and interrelationship of ABA and the classic defense hormone salicylic acid (SA) during progression of rice infection by the leaf blight pathogen Xanthomonas oryzae pv. oryzae (Xoo). Consistent with ABA negatively regulating resistance to Xoo, we found that exogenously administered ABA renders rice hypersusceptible to infection, whereas chemical and genetic disruption of ABA biosynthesis and signaling, respectively, led to enhanced Xoo resistance. In addition, we found successful Xoo infection to be associated with extensive reprogramming of ABA biosynthesis and response genes, suggesting that ABA functions as a virulence factor for Xoo. Interestingly, several lines of evidence indicate that this immune-suppressive effect of ABA is due at least in part to suppression of SA-mediated defenses that normally serve to limit pathogen growth. Resistance induced by the ABA biosynthesis inhibitor fluridone, however, appears to operate in a SA-independent manner and is likely due to induction of non-specific physiological stress. Collectively, our findings favor a scenario whereby virulent Xoo hijacks the rice ABA machinery to cause disease and highlight the importance of ABA and its crosstalk with SA in shaping the outcome of rice-Xoo interactions.
HEALTH AND LIFESTYLE TO SERVE THE PUBLIC

This study traces the changes of a prime-time health and lifestyle television programme (Puls) on the main channel of the Norwegian Broadcasting Corporation (NRK) across the last decade. The overall pattern of change is that as a public-service broadcaster, the NRK continues to broadcast factual programmes in prime time, which incorporate different entertainment and interactive elements to guarantee their popularity and relevance to the viewers. The integration of television and online activity has lessened over the years. The television content has become more lifestyle-oriented, while the Internet content has more stress on factual information and news. The use of reality elements has led to a strong emphasis on motivating the viewer to adopt an active lifestyle, while the viewers’ possibilities to participate actively in the programme have diminished.
A flexible hardware implementation of SHA-1 and SHA-2 Hash Functions

This paper summarizes the design of a reprogrammable Application Specific Integrated Circuit capable of performing all members of the Secure Hash Algorithm (SHA) group of Hash Functions. The need for high-speed cryptography is introduced, as well as the SHA-1 and SHA-2 Hash Functions and their operation. Work performed at other institutions to improve throughput and power consumption is presented with advantages and disadvantages discussed. The ASIC design is then discussed, with comparisons made to previously published ASIC and FPGA implementations. The possibility of using this ASIC architecture for the SHA-3 candidates, as well as the Message Digest (MD) families of Hash Functions is suggested as an area of future work as it is shown the ASIC Architecture designed would be capable of this with only program modifications required.
Oxidative Stress and Metabolic Syndrome: Cause or Consequence of Alzheimer's Disease?

Alzheimer's disease (AD) is a major neurodegenerative disease affecting the elderly. Clinically, it is characterized by a progressive loss of memory and cognitive function. Neuropathologically, it is characterized by the presence of extracellular β-amyloid (Aβ) deposited as neuritic plaques (NP) and neurofibrillary tangles (NFT) made of abnormal and hyperphosphorylated tau protein. These lesions are capable of generating the neuronal damage that leads to cell death and cognitive failure through the generation of reactive oxygen species (ROS). Evidence indicates the critical role of Aβ metabolism in prompting the oxidative stress observed in AD patients. However, it has also been proposed that oxidative damage precedes the onset of clinical and pathological AD symptoms, including amyloid-β deposition, neurofibrillary tangle formation, vascular malfunction, metabolic syndrome, and cognitive decline. This paper provides a brief description of the three main proteins associated with the development of the disease (Aβ, tau, and ApoE) and describes their role in the generation of oxidative stress. Finally, we describe the mitochondrial alterations that are generated by Aβ and examine the relationship of vascular damage which is a potential prognostic tool of metabolic syndrome. In addition, new therapeutic approaches targeting ROS sources and metabolic support were reported.
"The Hidden Client"--women caring for husbands with COPD: their experience of quality of life.

The purpose of this phenomenological study was to describe the experience of quality of life of women, taking care of husbands with chronic obstructive pulmonary disease (COPD). Unstructured, in-depth, tape-recorded personal interviews were used to collect data from six women living with husbands with COPD. The women ranged from 47 to 69 years in age and their husbands had given up work because of the illness. The wives in the study were dissatisfied with their lack of recreation, as well as support from friends, families and health care providers. Factors that increased the wife's quality of life were children and grandchildren and being able to please the husband and care for him until the very end.
DNA Damage/Repair and Polymorphism of the hOGG1 Gene in Lymphocytes of AMD Patients

Oxidative stress is thought to play a role in the pathogenesis of age-related macular degeneration (AMD). We determined the extent of oxidative DNA damage and the kinetics of its removal as well as the genotypes of the Ser326Cys polymorphism of the hOGG1 gene in lymphocytes of 30 wet AMD patients and 30 controls. Oxidative DNA damage induced by hydrogen peroxide and its repair were evaluated by the comet assay and DNA repair enzymes. We observed a higher extent of endogenous oxidative DNA damage and a lower efficacy of its repair in AMD patients as compared with the controls. We did not find any correlation between the extent of DNA damage and efficacy of DNA repair with genotypes of the Ser326Cys polymorphism. The results obtained suggest that oxidative DNA damage and inefficient DNA repair can be associated with AMD and the variability of the hOOG1 gene may not contribute to this association.
Transient Effect of Core Stability Exercises on Postural Sway During Quiet Standing

Kaji, A, Sasagawa, S, Kubo, T, and Kanehisa, H. Transient effect of core stability exercises on postural sway during quiet standing. J Strength Cond Res 24(2): 382-388, 2010-This study aimed to examine the transient effect of core stability exercises on the motion of the center of pressure (COP) during quiet standing. Seventeen healthy young adults (7 women and 10 men) were required to perform elbow-toe and hand-heel exercises for 30 seconds in both cases. Before and 1 minute after the execution of the 2 exercises, the subjects repeated 30 seconds of quiet standing with eyes closed 3 times on a force platform with intervals of 10 seconds between trials. The intervention of the 2 exercises induced significant decreases in the maximal range of mediolateral sway (34.7 ± 7.0 mm to 30.2 ± 6.1 mm, p = 0.0001), standard deviation of mediolateral sway (6.4 ± 1.2 mm to 5.8 ± 1.0 mm, p = 0.0006), the mean speed of anteroposterior sway (14.1 ± 2.5 mm per second to 13.2 ± 2.3 mm per second, p = 0.004), mean speed of mediolateral sway (22.8 ± 2.8 mm per second to 20.9 ± 2.3 mm per second, p = 0.004), sway speed (29.3 ± 3.9 mm per second to 27.0 ± 3.2 mm per second, p = 0.002), and sweep speed (73.2 ± 23.4 mm2 per second to 62.0 ± 19.7 mm2 per second, p = 0.005) of the COP trajectory, calculated from the force platform data. This result indicates that the practice of core stability exercises transiently decreases the area of the COP trajectory and its mediolateral and total excursions during quiet standing with the eyes closed. Performing core stability exercises as part of warm-up programs may be useful for temporarily improving postural control during standing in main exercise programs.
Pamphlet as a tool for continuing medical education: performance assessment in a randomized controlled interventional study

Background: Pamphlet is a tool used for distance continuous professional development programs. In this study, we assessed the impact of an educational pamphlet on improving prescription writing errors in general physicians’ performance. Methods: In this randomized controlled interventional study, we prepared a training pamphlet according to the most prevalent prescription writing problems. We randomized 200 participants among general physicians affiliated with Tehran Social Security Insurance Organization, and randomly divided them into intervention and control groups. Participants’ prescriptions (N= 34888) were investigated over a month, and then the prepared pamphlet was sent out to the participants in the intervention group. After three months we examined their one-month prescriptions again (N= 30296) and investigated the changes in prescription errors. Results: There was no significant difference in the mean number of prescriptions in two groups before and after intervention (p= 0.076). Mean number of medicinal items reduced significantly in intervention group. Also mean number of prescriptions including injection drugs (p= 0.024), Corticosteroids (p= 0.036), Cephalosporin (p= 0.017) and non-steroidal anti-inflammatory drugs (p=0.005) reduced significantly. No significant differences were found for other errors. Conclusion: This study showed that use of an appropriate pamphlet has a considerable impact on improving general physicians’ performance and could be applied for continuous professional development.
Marxism and Adult Education in Britain

In British adult education Marxism has been a persistent if marginalised current that has consistently informed its more radical movements and practitioners. This article firstly introduces some contested Marxist perspectives on adult education, particularly around the issues of ideology and incorporation into bourgeois society. Secondly, it examines the adult educational context, contrasting the themes of middle-class-provided ‘liberal’ adult education and ‘independent’ working-class education. It then focuses on the trajectories of workers’ education in the twentieth century and the contrasting roles Marxist education played in the Communist Party and the National Council of Labour Colleges up to the Second World War. In the post-war period the rebirth of community education in the 1960s and 1970s absorbed more cosmopolitan Marxist influence, such as those of Antonio Gramsci and Paulo Freire. The article ends by assessing what remains of the Marxist tradition in the twenty-first century and the authors conclude that in a capitalist system that remains deeply unequal and globally exploitative, Marxism still offers a valuable framework of analysis through which adult educators may be able to engage in a dialogue with emergent social movements.
Dynamically Scheduling VLIW Instructions

Very long instruction word (VLIW) machines potentially provide the most direct way to exploit instruction-level parallelism; however, they cannot be used to emulate current general-purpose instruction set architectures. In addition, programs scheduled for a particular implementation of a VLIW model cannot be guaranteed to be binary compatible with other implementations of the same machine model with a different number of functional units or functional units with different latencies. This paper describes an architecture, named dynamically trace scheduled VLIW (DTSVLIW), that can be used to implement machines that execute code of current RISC or CISC instruction set architectures in a VLIW fashion, with backward code compatibility. Preliminary measurements of the DTSVLIW performance, obtained with an execution-driven simulator running the SPECint95 benchmark suite, are also presented.
On the Origin of M81 Group Extended Dust Emission

Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic objects is both important and difficult. In this paper we discuss a particular case, the M81 group, and the identification of diffuse structures prominent in the infrared, but also detected at optical wavelengths. The origin of these structures has previously been controversial, ranging from them being the result of a past interaction between M81 and M82 or due to more local Galactic emission. We show that over an order of a few arcmin scales, the far-infrared (Herschel 250 μm) emission correlates spatially very well with a particular narrow-velocity (2–3 km s−1) component of the Galactic H i. We find no evidence that any of the far-infrared emission associated with these features actually originates in the M81 group. Thus we infer that the associated diffuse optical emission must be due to galactic light-back scattered off dust in our galaxy. Ultraviolet observations pick out young stellar associations around M81, but no detectable far-infrared emission. We consider in detail one of the Galactic cirrus features, finding that the far-infrared H i relation breaks down below arcmin scales and that at smaller scales there can be quite large dust-temperature variations.
