This research provides evidence regarding the causal effect of group conformity on task performance in stable and variable environments. Drawing on studies in cultural evolution, social learning, and social psychology, we experimentally tested the hypotheses that conformity improves group performance in a stable environment (H1) and decreases performance (by hindering adaptability) in a temporally variable environment (H2). We compare the performance of individuals, low conformity groups, and high conformity groups in a four-arm randomized lab (...) experiment (N = 240). High conformity was manipulated by rewarding agreement with the group’s majority and imposing a cost on disagreement. The monetary implications of conformity impaired performance in a variable environment but did not have a significant effect on performance in the stable environment. Intragroup individual-level analyses provide insights into the mechanisms that account for the group-level results by showing that lower conformity in groups facilitates efficient adaptability in the use of social information.

Software quality is one of the important elements of project management. Software review is one of the most cost effective techniques for detect and remove defects for improving software quality during software development life cycle. Literature suggests that experience and training have positive effect on software review performance. However, there is no empirical study conducted to analysis the important relationships between, experience, training and performance. A laboratory study was conducted with 192 volunteer university students to examining the above (...) relationships in a software review task. The results suggests that (1) there is positive relationships between role experience and performance, (2) training has no impact on performance, (3) working experience has an positive effect on performance (4) working experience has an impact and (5) role experience has no impact on performance.

In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared (...) against experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

Within a laboratory experiment we investigate a principal-agent game in which agents may, first, self-select into a group task (GT) or an individual task (IT) and, second, choose work effort. In their choices of task and effort the agents have to consider pay contracts for both tasks as offered by the principal. The rational solution of the game implies that contract design may not induce agents to select GT and provide positive effort in GT. Furthermore it predicts equal behavior (...) of agents with different productivities. In contrast, considerations of trust, reciprocity and cooperation – the social-emotional model of behavior – suggest that contract design can influence the agents’ willingness to join groups and provide effort. We analyze the data by applying a two-step regression model (multinomial logit and tobit) and find that counter to the rational solution, contract design does influence both, task selection and effort choice. The principal can increase participation in work groups and can positively influence group performance. Larger payment increases the share of socially motivated agents in work groups. The selection effect is larger than the motivation effect. (shrink)

This article explores the management and organisational context for capturing and retaining knowledge transferred through the design process. It is widely acknowledged that our ability to successfully organise and transfer design knowledge is dependant upon the context in which it is situated. However the knowledge generated through the creative process is often viewed from the perspective of the artefact rather the process itself. An understanding of the socially complex knowledge-based resources operating within design groups could enhance competitiveness and organisational development. (...) Yet, a systematic literature review of leading design and educational management journals found limited empirical evidence that shed light on the influence of knowledge management on design group performance. The article addresses this gap in the literature. Based on two in-depth case studies with interior design companies implementing new digital asset management systems over a 2-year period, the paper explores the findings in relation to design practice and policy, alongside implications for the contribution of the creative industries to the knowledge economy.

Research programs regularly compete to achieve the same goal, such as the discovery of the structure of DNA or the construction of a TEA laser. The more the competing programs share information, the faster the goal is likely to be reached, to society’s benefit. But the “priority rule”-the scientific norm according to which the first program to reach the goal in question must receive all the credit for the achievement-provides a powerful disincentive for programs to share information. How, then, is (...) the clash between social and individual interest resolved in scientific practice? This chapter investigates what Robert Merton called science’s “communist” norm, which mandates universal sharing of knowledge, and uses mathematical models of discovery to argue that a communist regime may be on the whole advantageous and fair to all parties, and so might be implemented by a social contract that all scientists would be willing to sign.

It is proposed that one musically interesting way to characterise and compare different performances or recordings of the same piece is by correlating them with different Schenkerian interpretations through the medium of grouping. This approach is demonstrated through an examination of four 'either/or' passages from the first movement of Beethoven's Piano Sonata in E Major, Op. 81a, passages in which at least two Schenkerian interpretations are possible. Schenker's own published and unpublished sketches, among others, are considered alongside recordings by Vladimir (...) Ashkenazy, Emil Gilels, Richard Goode, Murray Perahia and Artur Rubinstein. The approach is not meant to be self-sufficient, but rather to contribute a new set of tools to the emerging multidisciplinary field of performance studies. (shrink)

This paper explores the influence of group context on the ethical predispositions of group members. Results indicate that groups exert a powerful influence on individuals' ethical frameworks, and that the patterns of these influences differ depending on the type of ethical framework involved. Individuals' ethical utilitarianism was affected by both leadership style and group cohesiveness. Ethical formalism was most affected by the leadership style in the group.

Background. Sport training has an impact on other sciences. Among these sciences is physiology, in which emerged to form what is called sports physiology. The recent development in the science of physical education is one of the important factors in measuring and determining the nature of athletes' physical, physiological and biochemical adaptations and responses. The blood circulatory system is important as manifested in finding the relationship between some blood groups and the basic physical characteristics and the completion of the 100-meter (...) race. Objectives. The aim of this study is to identify the types of blood groups and their relationship to some physical traits, and the completion of the 100-meter race for some student athletes. Methods. the descriptive approach was used for its suitability to the research problem. The sample consisted of the students of second stage in the Department of Physical Education and Sports Sciences at Al-Mustaqbal University in Iraq. It was 143 students (35%) of the original research sample. With the a 143 sample size, the calculated confidence is 34.95 with standard deviation of ±3.87. Results. The study finds out a positive correlation between blood groups and some physical traits. There is also a positive correlation between blood groups and 100-meter sprint achievement as indicated from the statically data analysis and supported by the mean values 5.6 for O blood grouping. Conclusion. the blood group of athletes can take a role and impact on the speed and muscular strength tests. according to the results of this study the athletes who have AB and O blood group are more likely to win in 100 sprint races.

What is the relationship between electoral and economic performance? Previous literature posits that poor economic performance hurts the incumbent at the ballot box because overall economic performance serves as a competence signal, which voters can readily access at low costs. Building on an emerging economic voting literature exploring heterogeneity in the electorate, this article argues that social groups are affected differently by various dimensions of economic performance and that their sociotropic sanctioning of incumbents is contingent on (...) the retrospective performance of these dimensions. It theorizes how four social groups—low-skilled workers, pensioners, public sector employees, and high-income individuals—are differently affected by each of four economic dimensions: unemployment, inflation, stock market performance, and public spending; as a result, they penalize the incumbent to varying extents. Results from a multilevel logistic regression analysis from four modules of the Comparative Study of Electoral Systems containing around seventy electoral contexts are consistent with the argument.

This self-interview is the responsive document coming forth from the post-conference camaraderie. The four “Žižekian Performers” – found with themselves personally, creatively, and academically following the 2014 International Žižek Studies Conference. As a self-interview document that mimics the gameplay of Žižek himself in his own self-interview from his The Metastases of Enjoyment where he puts on the guise of the “big Other” to examine himself, we four performers here examine ourselves, each other, our work, and each other’s work to produce (...) this post-partum collaborative essay. In our collective project, we outline our individual performances from the Conference, each stake a claim and personal response to the critical question of what is a “Žižekian Performance,” and identify and discuss other synergies that emerged and exist amid our work in the form of cross-examinations and self-examinations. Ultimately, this group’s self-interview blazes the way for performance to interpenetrate the “Žižekian” and to intervene wherever theory, investigation, and presentation may lie. (shrink)

In the modern world, many important tasks have become too complex for a single unaided individual to manage. Teams conduct some safety-critical tasks to improve task performance and minimize the risk of error. These teams have traditionally consisted of human operators, yet, nowadays, artificial intelligence and machine systems are incorporated into team environments to improve performance and capacity. We used a computerized task modeled after a classic arcade game to investigate the performance of human–machine and human–human teams. (...) We manipulated the group conditions between team members; sometimes, they were instructed to collaborate, compete, or work separately. We evaluated players' performance in the main task (gameplay) and, in post hoc analyses, participant behavioral patterns to inform group strategies. We compared game performance between team types (human–human vs. human–machine) and group conditions (competitive, collaborative, independent). Adapting workload capacity analysis to human–machine teams, we found performance under both team types and all group conditions suffered a performance efficiency cost. However, we observed a reduced cost in collaborative over competitive teams within human–human pairings, but this effect was diminished when playing with a machine partner. The implications of workload capacity analysis as a powerful tool for human–machine team performance measurement are discussed. (shrink)

I explore how gender can shape the pragmatics of speech. In some circumstances, when a woman deploys standard discursive conventions in order to produce a speech act with a specific performative force, her utterance can turn out, in virtue of its uptake, to have a quite different force—a less empowering force—than it would have if performed by a man. When members of a disadvantaged group face a systematic inability to produce a specific kind of speech act that they are (...) entitled to perform—and in particular when their attempts result in their actually producing a different kind of speech act that further compromises their social position and agency—then they are victims of what I call discursive injustice. I examine three examples of discursive injustice. I contrast my account with Langton and Hornsby's account of illocutionary silencing. I argue that lack of complete control over the performative force of our speech acts is universal, and not a special marker of social disadvantage. However, women and other relatively disempowered speakers are sometimes subject to a distinctive distortion of the path from speaking to uptake, which undercuts their social agency in ways that track and enhance existing social disadvantages.

This book examines the performance of Bauls 'folk' performers from Bengal, in the context of a rapidly globalizing Indian economy and against the backdrop of extreme nationalistic discourses. Recognizing their scope beyond the musical and cultural realm, Sukanya Chakrabarti engages in discussing the subversive and transformational potency of Bauls and their performances. In-Between Worlds argues that the Bauls through their musical, spiritual, and cultural performances offer 'joy' and 'spirituality', thus making space for what Dr. Ambedkar in his famous 1942 (...) speech had identified as 'reclamation of human personality'. Chakrabarti destabilizes the category of 'folk' as a fixed classification or an origin point, and fractures homogeneous historical representations of the Baul as a 'folk' performer and a wandering mendicant exposing the complex heterogeneity that characterizes this group. Establishing 'folk-ness' as a performance category, and 'folk festivals' as sites of performing 'folk-ness', contributing to a heritage industry that thrives on imagined and recreated nostalgia, Chakrabarti examines different sites that produce varied performative identities of Bauls, probing the limits of such categories while simultaneously advocating for polyvocality and multifocality. While this project has grounded itself firmly in performance studies, it has borrowed extensively from fields of postcolonial studies and subaltern histories, literature, ethnography and ethnomusicology, and cosmopolitan studies.

Performance is an essential part of music education; however, many music professionals and students suffer from music performance anxiety (MPA). The purpose of this study was to investigate whether a 10-minute expressive writing intervention (EWI) can effectively reduce performance anxiety and improve overall performance outcomes in college-level piano students. Two groups of music students (16 piano major students and 19 group/secondary piano students) participated in the study. Piano major students performed a solo work from memory, (...) while group/secondary piano students took a sight-reading exam of an eight-measure piano musical selection. All students performed twice, at baseline and post-EWI, with two or three days between performances. During the EWI phase, students were randomly divided into two groups: an expressive writing group and a control group. Students in the expressive writing group wrote down feelings and thoughts about their upcoming performances, while students in the control group wrote about a topic unrelated to performing. Each student’s pulse was recorded immediately before performing, and each performance was videotaped. Three independent judges evaluated the recordings using a modified version of the Observational Scale for Piano Practicing (OSPP) by Gruson (1988). The results revealed that, by simply writing out their thoughts and feelings right before performing, students who had high MPA improved their performance quality significantly and reduced their MPA significantly. Our findings suggest that EWI may be a viable tool to alleviate music performance anxiety. (shrink)

Teachers have a very important role in determining the quality of the teaching-learning process and the students’ learning outcomes. Learning outcomes will optimally be achieved if it is supported by qualified teachers. One way to enhance the teachers’ performance is through instructional supervision which can be divided into two techniques, namely group and individual supervision techniques. Therefore, this study aims to find out the influence of instructional supervision techniques on the work motivation and performance of elementary school (...) teachers. This study was conducted in East Java, Indonesia, and an explanatory research design was used. The sample was taken from 80 elementary school teachers in Malang and Blitar using a multi-stage random sampling technique. Data were collected through the use of questionnaires and documentation, and then they were analyzed by using the structural equation modeling technique. The result of this study showed that group supervision has a significant effect on teachers’ performance, whereas individual supervision influenced teachers’ work motivation and it affected their performance.

The present study examined how exposure to the performance of in-group and out-group members can both exacerbate and minimize the negative effects of stereotype threat. Female participants learned that they would be taking a math test that was either diagnostic or nondiagnostic of their math ability. Prior to taking the test, participants interacted with either an in-group peer (a female college student) or an out-group peer (a male college student) who had just taken the test (...) and learned that the student had either performed well or poorly on the test. Exposure to either an in-group or an out-group peer whose performance was consistent with the negative stereotype (a poor-performing female or a strong-performing male) exacerbated stereotype threat effects. In contrast, exposure to an in-group or an out-group peer whose performance challenged the negative stereotype (a strong-performing female or a poor-performing male) eliminated stereotype threat effects. These findings demonstrate that people can look to both in-group and out-group peers as sources of inspiration in the context of a negative stereotype. (shrink)

This paper reports a Contingent Valuation application to estimate the non-market costs and benefits of hydro scheme developments in an Icelandic wilderness area. A deliberative group -based approach, called Market Stall, is compared to a control group consisting of conventional in-person interviews, in order to investigate flaws of Contingent Valuation, such as poor validity and protest responses. Perceived property rights suggested the use of willingness-to-accept in compensation for wilderness loss and willingness-to-pay for hydro scheme benefits. The study is (...) novel as it applies participant behaviour observation to gain insights into the shortcomings of conventional data collection modes. Main drawbacks with in-person interviews were found to be low motivation, standardised information and time pressure which hindered individuals from carefully considering their preferences. Market Stall performed better in the study: welfare estimates were more easily explained by socio-economic variables, the non-response rate was lower, and respondents were more engaged. Our research findings also suggest that participant behaviour can be used to supplement conventional validity tests. (shrink)

Do children derive different benefits from group collaboration at different ages? In the present study, 183 children from two age groups took part in a class quiz as members of a group, or individually. In some groups, cohesiveness was made salient by awarding prizes to the top performing groups. In other groups, prizes were awarded to the best performing individuals. Findings, both in terms of social outcomes and performance in the quiz, indicated that the 8-year olds viewed (...) the benefits of group membership in terms of the opportunities to receive information from other members. The 13-year olds, in contrast, viewed group collaboration as a constructive process where success was connected with group cohesiveness. (shrink)

Cardiopulmonary resuscitation is frequently performed on patients who, in retrospect, had a very low chance of survival. This is because all patients are ‘For cardiopulmonary resuscitation’ on admission to hospital by default, and delays occur before cardiopulmonary resuscitation can be ‘de-prescribed’.

The moral and operational feasibility of a model in which informed consent must be obtained before cardiopulmonary resuscitation is attempted in some patient groups is then explored. (shrink)

This book brings together a distinguished group of scholars from music, drama, poetry, performance art, religion, classics and philosophy to investigate the complex and developing interaction between performance and authenticity in the arts. The volume begins with a perspective on traditional understandings of that relation, examining the crucial role of performance in the Poetics, the marriage of art with religion, the experiences of religious and aesthetic authenticity, and modernist conceptions of authenticity. Several essays then consider music (...) as a performative art. The final essays discuss the link of authenticity to sincerity and truth in poetry, explain how performance, as an authentic feature of poetry, embodies a collective effort, and culminate in a discussion of the dark side of performance - its constant susceptibility to inauthenticity. Together the essays suggest how issues of performance and authenticity enter into consideration of a wide range of the arts. (shrink)

Early-Onset Schizophrenia (EOS) and Attention Deficit-Hyperactivity Disorder (ADHD) are early- onset neurodevelopmental disorders associated with cognitive deficits. The current study represents the first attempt to compare these groups on a comprehensive cognitive test battery in a longitudinal design over 25 years in order to enhance our knowledge of particular patterns resulting from the interaction between normal maturational processes and different illness processes of these disorders. In the baseline study, 19 adolescents with schizophrenia were compared to 20 adolescents with ADHD and (...) 30 healthy controls (HC), all between 12 and 18 years of age. After 13 years (T2) and after 25 years (T3) they were re-evaluated with the cognitive test battery. A cognitive Composite Score was used in a linear mixed model. The EOS group had a significant cognitive stagnation or deterioration from T1 to T2 compared to HC. However, the EOS group had the most positive change from T2 to T3, supporting a stable level of cognitive performance over the 25 year span. The ADHD group improved or had similar development as the HC group from T1 to T2. They continued to improve significantly compared to the HC group from T2 to T3. Individuals in the EOS group performed more impaired on the cognitive composite score compared to the HC group and the ADHD group at all three time points. Results might indicate a neurodevelopmental pathway of EOS with subnormal cognitive development specific in adolescence. In comparison, the ADHD group had a more consistent cognitive maturation supporting a maturational delay hypothesis of ADHD. (shrink)

Our beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true. Sometimes this is for the good because our peers help us form a more accurate opinion. Sometimes it is for the worse because we are led astray. In this context, we address via agent-based computer simulations the extent to which patterns of connectivity within our social networks affect the likelihood that initially undecided agents in a network converge on a (...) true opinion following group deliberation. The model incorporates a fine-grained and realistic representation of belief and trust, and it allows agents to consult outside information sources. We study a wide range of network structures and provide a detailed statistical analysis concerning the exact contribution of various network metrics to collective competence. Our results highlight and explain the collective risks involved in an overly networked or partitioned society. Specifically, we find that 96% of the variation in collective competence across networks can be attributed to differences in amount of connectivity and clustering, which are negatively correlated with collective competence. A study of bandwagon or “group think” effects indicates that both connectivity and clustering increase the probability that the network, wholly or partly, locks into a false opinion. Our work is interestingly related to Gerhard Schurz’s work on meta-induction and can be seen as broadly addressing a practical limitation of his approach. (shrink)

This study examines how subtitlers in underground subtitle groups in China perform skills and display competence in applying the rules around which annotations are built. I argue that by annotating, the act of creating notes, representing information not linguistically coded in the original US TV programs, subtitlers engage in a performative act in concert. Annotations reveal not only subtitlers’ stances toward the contents being translated, but also their meta­thinking on these contents. The analysis shows that two contradictory forces provide the (...) impetus for annotations. On the one hand, the desire for objectivity refers to subtitlers’ attempts to represent a professional and organized account of how Chinese subtitles are produced in the process of explicating knowledge. On the other hand, the desire for authenticity is implicit in the subtitlers’ narrative of what they actually experience when translating US TV programs. (shrink)

The possible differential effects of ABO blood group materno-paternal (fetal) incompatibility on completed reproductive performance were investigated on a sample of 100 couples (100 fathers and 100 mothers) from three villages in the Jind district of Haryana state, India. The average number of live births per mating couple was slightly higher for the incompatible matings (5·32) than the compatible ones (5·05). This advantage was offset by higher postnatal mortality in the former. Consequently, the average number of living children (...) in the compatible matings (4·64) was higher than in the incompatible ones (4·18). With reference to individual ABO matings, the index of relative fertility (Irf) was the highest in A×AB followed by B×A type of incompatible matings. No decrease in live births in O×A and O×B incompatible matings was observed compared with their reciprocal compatible ones, i.e. A×O and B×O matings, as has been hypothesized in previous studies. The total pregnancy wastage was substantially higher in ABO-incompatible matings (24·59%) than compatible matings (8·45%). About 71% of the postnatal deaths took place within one year of the birth in the case of incompatible matings compared with 50% in the case of compatible matings. The study supports the hypothesis that selection is operative at the ABO locus as revealed by the measures of selection intensity. The loss of fitness in the present sample was associated with differential mortality. There were no differences in the proportions of average number of male live births in the compatible (0·55) and incompatible matings (0·58). However, in the individual mating types, there was some evidence of higher or lower proportions of male live births. (shrink)

Biology is seen not merely as a privileged oppressor of women but as a co-victim of masculinist social assumptions. We see feminist critique as one of the normative controls that any scientist must perform whenever analyzing data, and we seek to demonstrate what has happened when this control has not been utilized. Narratives of fertilization and sex determination traditionally have been modeled on the cultural patterns of male/female interaction, leading to gender associations being placed on cells and their components. We (...) also find that when gender biases are controlled, new perceptions of these intracellular and extracellular relationships emerge. (shrink)

Music performance anxiety (MPA) is a multifaceted phenomenon occurring on a continuum of severity. In this survey study, we investigated to what extent the affective (anxiety), cognitive (catastrophizing), and somatic (bodily complaints) components of MPA prior to solo performances vary as a function of age, gender, instrument group, musical experience, and practice as well as how these MPA components relate to self-rated change in performance quality from practice to public performance. The sample comprised 75 male and (...) 111 female classical music university students, aged 15–45 years. Age was positively associated with anxious feelings and bodily complaints. Compared to male students, female students reported significantly more anxious feelings and catastrophizing. Singers reported less anxious feelings and catastrophizing than instrumentalists. Breathing-, mouth- and throat-related complaints were highest among singers and wind players; hand- and arm-related complaints were highest among string players and pianists. The indices of musical experience and practice had marginal effects. An average of four bodily complaints bothered the participants strongly to very strongly. Worsening in performance quality from practice to public performance was reported by almost half of the participants and was best predicted by anxious feelings and breathing-related complaints. We conclude that age, gender and instrument play a significant role in understanding the phenomenology of MPA. Musicians should be examined according to these characteristics rather than as one homogenous population. In particular, it might be valuable to develop assessment tools for MPA that incorporate items related to the bodily complaints that are most relevant to the different instrument groups. Breathing-related complaints could add an important dimension to the investigation of MPA and music performance. Finally, the high percentage of students reporting worsening of their performance quality from practice to public performance highlights the need of professional support to help music students be able to perform at their best and thrive as artists.

Humans are fundamentally social and tend to create emergent organizations when interacting with each other; from dyads to families, small groups, large groups, societies and civilizations. The study of the neuronal substrate of human social behavior is currently gaining momentum in the young field of social neuroscience. Hyperscanning is a neuroimaging technique by which we can study two or more brain simultaneously while participants interact with each other. The aim of this article is to discuss several factors that we deem (...) important in designing hyperscanning experiments. We first review hyperscanning studies performed by means of electroencephalography (EEG) that have been relying on a continuous interaction paradigm. Then, we provide arguments for favoring ecological paradigms, for studying the emotional component of social interactions and for performing longitudinal studies, the last two aspects being largely neglected so far in the hyperscanning literature despite their paramount importance in social sciences. Based on these premises we argue that music performance is a suitable experimental setting for hyperscanning and that for such studies EEG is an appropriate choice as neuroimaging modality. (shrink)

The goal of this article is to present the possibility of using Diagnosis- Related Groups (DRG) in the hospital management process and to analyse the need for business performance management on the part of hospital management staff. The following research methods were used: literature analysis, case studies, and poll analysis. It is not possible to increase the effectiveness of operation of healthcare entities without increasing the importance of IT systems and using DRG more effectively in the management process. Training (...) users in IT and the use of DRGs is important to achieving hospital effectiveness. The increased importance of analyses and planning in a hospital should be reflected in the organisational structure of service providers. Hospital controllers should have a similar role to those present in most companies in other industries. (shrink)

The goal of this paper is to examine whether business performance is affected by the adoption of practices included under the term Corporate Social Responsibility (CSR). To achieve this goal, we analyse the relation between CSR and certain accounting indicators and examine whether there exist significant differences in performance indicators between European firms that have adopted CSR and others that have not. The effects of compliance with the requirements of CSR were determined on the basis of firms included (...) in the Dow Jones Sustainability Index (DJSI), and specific accounting indicators were applied to measure performance. For the purposes of this study, we selected one group of firms belonging to the DJSI and another comprised of firms quoted on the Dow Jones Global Index (DJGI) but not on the DJSI. The sample was made up of two groups of 55 firms, studied for the period 1998–2004. Empirical analysis supports the conclusion that differences in performance exist between firms that belong to the DJSI and to the DJGI and that these differences are related to CSR practices. We find that a short-term negative impact on performance is produced. (shrink)

There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries and for different periods of time serve as (...) reference for evaluation. The ultimate conclusion of all of these studies is that there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries. In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method, comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice. (shrink)

To investigate whether making performance predictions affects prospective memory processing, we asked one group of participants to predict their performance in a PM task embedded in an ongoing task and compared their performance with a control group that made no predictions. A third group gave not only PM predictions but also ongoing-task predictions. Exclusive PM predictions resulted in slower ongoing-task responding both in a nonfocal and in a focal PM task. Only in the nonfocal (...) task was the additional slowing accompanied by improved PM performance. Even in the nonfocal task, however, was the correlation between ongoing-task speed and PM performance reduced after predictions, suggesting that the slowing was not completely functional for PM. Prediction-induced changes could be avoided by asking participants to additionally predict their performance in the ongoing task. In sum, the present findings substantiate a role of metamemory for attention-allocation strategies of PM. (shrink)

In recent years, the microfinance industry has received a substantial amount of cross-border funding from both public and private sources. This funding reflects the increasing interest in microfinance as part of a more general trend towards socially responsible investments. In order to be able to secure sustained interest from these investors, it is important that the microfinance industry can show evidence of its contribution to reducing poverty at the bottom of the pyramid. For this, it is crucial to understand under (...) what conditions microfinance institutions are able to reduce poverty. This paper contributes to this discussion by investigating the relationship between the extent to which social capital formation is facilitated within different societies and the financial and social performance of MFIs. This focus on social capital formation is important, because in many cases MFIs use group loans with joint liability to incentivize asset-poor borrowers to substitute the lack of physical collateral by their social capital. Hence, the success of a large part of the loan relationship between MFIs and their borrowers depends on the social capital those borrowers can bring into the contract. We carry out a cross-country analysis on a dataset containing 100 countries and identify different social dimensions as proxies for how easy social capital can be developed in different countries. We hypothesize that microfinance is more successful, both in terms of their financial and social aims, in societies that are more conducive to the development of social capital. Our empirical results support our hypothesis. (shrink)

Performing Difference is a compilation of seventeen essays from some of the leading scholars in history, criticism, film, and theater studies. Each author examines the portrayal of groups and individuals that have been traditionally marginalized or excluded from dominant historical narratives. As a meeting point of several fields of study, this book is organized around three meta-themes: race, gender, and genocide. Included are analyses of films and theatrical productions from the United States, as well as essays on cinema from Southern (...) and Central America, Europe, and the Middle East. Topically, the contributing authors write about the depiction of race, ethnicities, gender and sexual orientation, and genocides. This volume assesses how the performing arts have aided in the social construction of the "other" in differing contexts. Its fundamental premise is that performance is powerful, and its unifying thesis is that the arts remain a major forum for advancing a more nuanced and humane vision of social outcasts, not only in the realm of national imaginations, but in social relations as well."--Jacket.

The impact of digital media and technology on performance arts is evident when digital visual effects (VFX) filming techniques are introduced on a film set. Digital technologies influence the film actor’s approach to be congruent to and authentic within the circumstances of the scene. Actors require an effective skillset and strategies to successfully deliver an embodied performance aligning with the various digital VFX techniques. Focusing on imagination, action and emotion that would facilitate such an embodied performance, we (...) drew on relevant neuroscientific notions such as neuron reactivation, conceptual blending, as-if body states and affordances. Additionally, we incorporated relevant embodied performance concepts from Stanislavski, Laban/Bartenieff Movement Studies, Effector Patterns including the Emotional Body Approach and Lessac Kinesensics to the development of a digital acting programme, advancing the actor’s required skills and providing on-set digital acting strategies to support congruency with digital VFX and authenticity within the diegetic reality. The efficacy of this programme was determined by assessing pre- and post-intervention recordings of both a control and an experimental group of trained actors. Reflection-on-action journals from participants supplemented the assessment. The assessments and journals indicate that the acquired skillset and on-set digital acting strategies effectively improve the actor’s performance with digital VFX filming technology. (shrink)

Having the ambition to contribute to the practical value of the theory on corporate social performance (CSP), this paper approaches the question whether CSP can contribute to the competitive advantage of firms. We adopted an explorative case-study methodology to explore the variety of positive and negative effects of CSP on the competitiveness of organizations. As this study aimed at identifying as great variety of these effects as possible, we selected a diversified group of respondents. Data was thus collected (...) through embedded units of analysis in a petrochemical company, and triangulated with the opinions of experts on CSP. Overall, we found various positive and negative effects of CSP on the competitiveness of organizations. CSP is therefore not an innocent adventure for executives, but rather a strategy for achieving corporate objectives. If not carefully implemented, the CSP strategy may harm the competitive advantage of the firm, as our results have suggested. (shrink)

Previous research has documented that type 2 diabetes mellitus is associated with cognitive impairment. Psychological variables were repeatedly investigated to understand why T2DM patients are poorly active, despite standards of medical care recommends performing aerobic and resistance exercise regularly and reducing the amount of time spent sitting. This exploratory study aims to investigate how affective variables as thoughts, feelings, and individuals’ stage of exercise adoption can modulate low cognitive performances during an experimental procedure based on exercise. The Exercise Thoughts Questionnaire, (...) Exercise-Induced Feeling Scale, and Physical Activity Stage of Change were administered to a sample of 12 T2DM patients. The Bivalent Shape Task alone, BST with exercise [control exercise recovery + BST], and BST with metaboreflex [post-exercise muscle ischemia + BST] were used as mental task, and response time to congruent, incongruent, and neutral stimuli was recorded. Concomitant cerebral oxygenation was evaluated by near-infrared spectroscopy. As expected, T2DM patients performed significantly better when the stimulus was presented in congruent trials. In the CER + BST session, T2DM patients showed longer reaction time to incongruent trials than in the PEMI + BST and BST alone sessions. Positive feelings toward exercise seem to modulate cognitive performances in high challenging task only if T2DM patients were conscious to play exercise. These results could provide some insights for health intervention targeting exercise for patients with T2DM in order to enhance cognitive performances. (shrink)

What stands out when we blend in? Performing Ground is the first book to explore camouflage as a performance practice, arguing that the act of blending into one's environment is central to the ways we negotiate our identities in and through space. Laura Levin tracks contemporary performances of camouflage through a variety of forms - performative photography; environmental, immersive, and site-specific performance; activist infiltration; and solo artworks - and rejects the conventional dismissal of blending in as an abdication (...) of self. Instead, she contemplates the empowering political possibilities of 'performing ground,' of human bodies intermingling with the material world, while directly engaging with the reality that women and other marginalized persons are often relegated to the background and associated with the properties of space. Performing Ground engages these questions through the works of some of today's most exciting performance artists such as Rebecca Belmore, Liu Bolin, Janieta Eyre, and Violeta Luna, and groups like Gob Squad, Punchdrunk, The Yes Men, and Urban Mimics.

In the present political and socio-cultural situation in Slovakia, it is natural and necessary even to ask “what position do the arts occupy in this country?” and “what role do they play within the complex global atmosphere?” Art and culture should mirror the nation. Are we aware of that? Do we realize that art has the ability and the power to move? Not many of us realize this. This is a consequence of the permanent scepticism, apathy and resentment caused by (...) the fact that this voice has never been heard. And this is not just the case in Slovakia. Yet even today there are certain groups of artists who still believe in the arts and their power. I think that giving up on this faith is the easiest thing to do. The decision whether to fight, rebel or actively participate is extremely complex and in many cases doing so may even threaten the freedom of the person. In this article I address the issue of whether art has the power and ability to change things. I draw attention to those socially engaging activities that could be described as performance art, which occur beyond enclosed areas and in public spaces; and in order to achieve change, they openly and nakedly attack individual consciousness and the subconscious.
