Despite external environmental changes in walking, such as manipulating gait speed, previous studies have shown that the underlying muscle synergy structures (synergy weights or vectors) rarely vary. The purpose of this study is to examine if external environmental changes to the walking task influence muscle synergies in children with cerebral palsy (CP) and/or typical development (TD). To identify muscle synergies, we extracted muscle synergies from eight children with CP and eight age-matched TD in three treadmill walking conditions, e.g., baseline (adjusted (...) to individual comfortable walking speed), variable speed (VS), or restricted foot width (RW). Then, we grouped similar muscle synergies using k-mean clustering and discriminant analyses from all datasets of individual synergy structures. Proportion tests exhibited six clusters of muscle synergies predominantly arising from children with CP and four clusters from children with TD. Also, the proportion of muscle synergies was significantly different in four of the CP-preferred clusters across conditions. Specifically, the proportion of the baseline condition was significantly different from VS and RW conditions in one and two clusters, respectively. The proportion was significantly different between VS and RW conditions in four clusters. Cadence and step lengths differed across conditions but not groups which makes the group differences in proportion even more notable. In contrast, step width, while significantly lower in CP, did not differ across conditions. Our findings demonstrate that muscle synergies in children with CP are more sensitive to changes in the external walking environment than in typically developing children. (shrink)

Strip clubs have rarely been analyzed in terms of their gendered organization. Instead, the literature on stripping emphasizes interaction-based perspectives that focus on strippers, patrons, and broader macro-structural trends. Although interaction-based perspectives are valuable, they often neglect to consider the context in which these interactions take place, the strip club itself. Such studies also tend to neglect the larger cast of club characters who own, manage, and work. This study explores workplace dynamics in The Lion's Den, a club featuring nude (...) female dancers who perform primarily for male patrons. Informed by feminist and gendered organizational theory, this research utilizes sociologist Joan Acker's framework for studying gendered organizations as a way of augmenting interaction-based perspectives. Applying her approach to a strip club, an overtly gendered setting, this research demonstrates the importance of context in facilitating particular gendered processes, stereotypes, and gendered substructures.

It seems obvious that blood itself is the most appropriate fluid to replace blood, and there is no doubt as to its efficacy. On the other hand, to my surprise, it has not shown itself, experimentally, to be so much superior to certain artificial solutions, such as gum arabic, as I expected.

Narrative Science examines the use of narrative in scientific research over the last two centuries. It brings together an international group of scholars who have engaged in intense collaboration to find and develop crucial cases of narrative in science. Motivated and coordinated by the Narrative Science project, funded by the European Research Council, this volume offers integrated and insightful essays examining cases that run the gamut from geology to psychology, chemistry, physics, botany, mathematics, epidemiology, and biological engineering. Taking in shipwrecks, (...) human evolution, military intelligence, and mass extinctions, this landmark study revises our understanding of what science is, and the roles of narrative in scientists' work. This title is also available as Open Access. (shrink)

Der Band versammelt Beiträge des Deutsch-Japanischen Rechtsdialogs in Augsburg. Mit dem Generalthema «Straftheorie und Strafgerechtigkeit» werden Grundfragen des Straf- und Strafprozessrechtes aufgegriffen. Warum bestrafen wir? Wie sind Strafen und wie ist der Strafprozess angemessen auszugestalten, um Gerechtigkeit und Rechtsfrieden zu erreichen? Wie können Bürgerrechte hinreichend geschützt werden? Diese Fragen werden vor dem Hintergrund eines wachsenden Sicherheitsbedürfnisses in den Gesellschaften Japans und Deutschlands erörtert.

We report on the experience of creating a socially networked system, the Research-oriented Social Environment , for representing knowledge in the form of relationships between people, documents, and groups. Developed as an intercampus, interdisciplinary project of the University of California, this work reflects on a collaboration between scholars in the humanities, software engineering, and information studies by providing an opportunity not only to synthesize different disciplinary perspectives, but also to interrogate and challenge the assumptions each brings to team-based design projects (...) in the digital humanities. This work examines socially networked knowledge as both content and methodology for collaboration, calling for further critique and future investigation of epistemological questions in models of social networks.

AimHealthcare workers have directly provided care for COVID-19 patients, and have faced many additional sources leading to poor mental health. The study aimed to investigate the mental health problems and related factors among healthcare staff in Vietnam.MethodsA descriptive cross-sectional mixed methods study, combining quantitative and qualitative research methods, was performed among 400 healthcare workers working at the National Hospital for Tropical Diseases and Ninh Binh General Hospital from the first day of treatment for COVID-19 patients to May 01, 2020.ResultsThe results (...) showed that 8.0% of participants had stress, 17.5% of participants had anxiety, and 14.8% of participants had depression. Approximately 50% of participants reported that they had at least one of these symptoms. The findings illustrated that stress, anxiety, and depression were associated with the position in a hospital, health status during the COVID-19 pandemic, family members/relatives infected with COVID-19, physical and mental support from friends, family, and community, department, years of working, and the average work hours per day of healthcare workers exposed to COVID-19.ConclusionDuring the COVID-19 pandemic, healthcare workers who worked in the hospital providing treatment and care for COVID-19 patients dealt with mental health problems such as stress, anxiety, and depression. It is necessary to promote mental health among healthcare workers, to contribute to the fight against the COVID-19 outbreak in Vietnam. (shrink)

I dispute the claim that the disclosure of the life-world by phenomenology is an accomplishment of 'permanent' significance. By briefly reviewing the meaning of the "world" and "life-world" in the writings of Husserl, Gurwitsch, Schutz-Luckmann, Ortega, Heidegger, Jonas, Straus, Sartre and Merleau-Ponty, I show that they all treat the world, or rather the affairs which comprise it, as passively present whether viewed as a mental acquisition or as the "Other." But the meaning of the world-as that wherein are met physical (...) demands upon us which must be satisfied if we are to continue living-cannot be considered either as a mental acquisition or as something that is "other" and over against us. A living being as living cannot fail to attend to the agency of the affairs of which the life-world consists, as well as one's own exploring and coping actions. If we are to really speak of life, then we must acknowledge the mutual and reciprocal activities of living beings and world. (shrink)

Using the scope of justice perspective (Deutsch in J Soc Issues 31(3):137–149, 1975 ; Opotow in Conflict, cooperation, and justice: essays inspired by the work of Morton Deutsch, 1995 , J Soc Issues 52:19–24, 1996 ), we examined whether and how the relationship between perceived discrimination against minorities at work (i.e., racial minorities and females) and citizenship behavior toward minorities can be modified by personal value for diversity. Based on a survey of 173 employees, unexpectedly, we found a negative relationship (...) between perceived discrimination against minorities at work and citizenship behavior toward minorities. However, consistent with our expectations and the scope of justice, we found that the negative relationship was attenuated for those high in personal value for diversity. (shrink)

Feminized care work occupations have traditionally paid lower wages compared to non–care work occupations when controlling for human capital. However, when men enter feminized occupations, they often experience a “glass escalator,” leading to higher wages and career mobility as compared to their female counterparts. In this study, we examine whether men experience a “wage penalty” for performing care work in today’s economy, or whether the glass escalator helps to mitigate the devaluation of care work occupations. Using data from the Survey (...) of Income and Program Participation for the years 1996-2011, we examine the career patterns of low- and middle-skill men in health care occupations. We found that men in occupations that provide the most hands-on direct care did experience lower earnings compared to men in other occupations after controlling for demographic characteristics. However, men in more technical allied health occupations did not have significantly lower earnings, suggesting that these occupations may be part of the glass escalator for men in the health care sector. Minority men were significantly more likely than white men to be in direct care occupations, but not in frontline allied health occupations. Male direct care workers were less likely to transition to unemployment compared to men in other occupations. (shrink)

We argue that Stanford’s picture of the evolution of externalised norms is plausible mostly because of the idealisations implicit in his defence of it. Once we take into account plausible amounts of normative disagreement, plausible amounts of error and misunderstanding, and the knock-on consequences of shunning, it is plausible that Stanford under-counts the costs of externalisation.

To ensure their survival in natural habitats, plants must recognize and respond to a wide variety of insect herbivores. Aphids and other Hemiptera pose a particular challenge, because they cause relatively little direct tissue damage when inserting their slender stylets intercellularly to feed from the phloem sieve elements. Plant responses to this unusual feeding strategy almost certainly include recognition of aphid salivary components and the induction of phloem‐specific defenses. Due to the excellent genetic and genomic resources that are available for (...) Arabidopsis thaliana (Arabidopsis), this plant was chosen as a model system to study the metabolic and transcriptional responses to infestation by two aphids, Myzus persicae (green peach aphid, a broad generalist) and Brevicoryne brassicae (cabbage aphid, a crucifer‐feeding specialist). Future research on Arabidopsis–aphid interactions will lead to the identification of aphid‐specific elicitors, components of the defense‐signaling pathway, and additional metabolic responses that are induced by aphid infestation.

A persistent belief in American culture is that males both outperform and have a higher inherent aptitude for mathematics than females. Using data from two school districts in two different states in the United States, this study used longitudinal multilevel modeling to examine whether overall performance on standardized as well as classroom tests reveals a gender difference in mathematics performance. The results suggest that both male and female students demonstrated the same growth trend in mathematics performance (as measured by standardized (...) test scores) over time, but females' mathematics grade-point average is significantly higher than males. These results are discussed in the context of present day standardized assessment in the United States that may motivate teachers to focus on higher expectations for mathematics performance regardless of gender, thus challenging cultural beliefs that stigmatize mathematics as masculine in the United States.
