Diffusion MRI is widely used to investigate neuronal and structural development of brain. dMRI data is often contaminated with various types of artifacts. Hence, artifact type identification in dMRI volumes is an essential pre-processing step prior to carrying out any further analysis. Manual artifact identification amongst a large pool of dMRI data is a highly labor-intensive task. Previous attempts at automating this process are often limited to a binary classification of the dMRI volumes or focus on detecting a single type (...) of artifact. In this work, we propose a deep learning-based automated multiclass artifact classifier for dMRI volumes. Our proposed framework operates in 2 steps. In the first step, the model predicts labels associated with 3D mutually exclusive collectively exhaustive sub-volumes or “slabs” extracted from whole dMRI volumes. In the second step, through a voting process, the model outputs the artifact class present in the whole volume under investigation. We used two different datasets for training and evaluating our model. Specifically, we utilized 2,494 poor-quality dMRI volumes from the Adolescent Brain Cognitive Development and 4,226 from the Healthy Brain Network dataset. Our results demonstrate accurate multiclass volume-level main artifact type prediction with 96.61 and 97.52% average accuracies on the ABCD and HBN test sets, respectively. Finally, in order to demonstrate the effectiveness of the proposed framework in dMRI pre-processing pipelines, we conducted a proof-of-concept dMRI analysis exploring the relationship between whole-brain fractional anisotropy and participant age, to test whether the use of our model improves the brain-age association.

This article contributes to the literature on legitimacy by highlighting its paradox and constraints. While an optimal level of legitimacy-seeking behaviours may be necessary for organizational effectiveness, an excessive focus on legitimacy may lead to stakeholder mismanagement and have the opposite effect. These insights emerged from a longitudinal qualitative study of large-scale changes in public-sector health care in a Canadian province (1994-2002). In 1994, subordinate health care organizations underwent government-driven reforms to promote market-based logics of efficiency and cost reduction. Initial (...) years post reforms were characterized by a singular focus on government-driven priorities and inattention to other stakeholders. However, instead of giving benefits of legitimacy, these behaviours led to anger and activism from non-institutional stakeholders such as staff and community due to a decline in quality and patient satisfaction. Eventually, greater attention to stakeholder concerns ended the stand-off. These findings also elaborate Suchman's (Academy of Management Review 20(3), 571-610, 1995) framework on legitimacy and explain that legitimacy may occur for reasons other than institutionalization of values and be temporary in nature.

This mixed-methods case study describes the experiences of a rural health organization in Canada that was a pioneer in undergoing institutionally driven radical change. This change was advocated by senior managers and physicians with the strong backing of the government. The senior managers and physicians made a strong case for the radical change and argued that a focus on efficiency and wellness would lead to improved service and quality of patient-care. However, this radical change initiative was resisted by nurses and (...) support staff who perceived that these changes were being driven by market-based institutional logics and questioned their ethical appropriateness in a public system. They also expressed a lack of trust given the large-scale layoffs in a prior restructuring. These findings run counter to extant theory by highlighting the role of agency despite institutional pressures. Specifically, change implementers not only face the burden of justifying ethical appropriateness of institutional logics, but also are required to engage in persuasive discourse that these institutional logics protect the interests of the members.

Organizations have increasingly relied on team-based reward systems to boost productivity and foster collaboration. Drawing on the literature on ethics and justice as well as appraisal theories of emotion, we examine how team-based reward systems can have an insidious side effect: They increase the likelihood that employees remain silent when observing a team member engage in unethical behavior. Across four studies adopting different methods, measures, and samples, we found consistent evidence that people are less likely to report (i.e., speak up (...) or provide anonymous feedback about) a team member’s unethical behavior in team-based than in individual-based reward systems. Furthermore, our research reveals that this effect is primarily driven by a decrease in the experience of moral anger, which subsequently leads to a decreased likelihood of reporting unethical behavior when it benefits the team rather than the individual. We do not find support for perceived indirect benefit or envy as alternative explanations, suggesting that the decision to report a team member’s unethical behavior is not driven by calculative and selfish motives, but by moral motives. Finally, we establish that the effect is contingent on the observer and the perpetrator being members of the same team; it dissipates when the observer and the perpetrator are part of different teams. Our work contributes to research on reward systems and business ethics and provides practical implications for human resource practices. (shrink)

This paper investigates the relationship between mental health and pastoral care in the Church. The principal goal is to indicate the area of dialogue and cooperation between pastoral theology / pastoral psychology and psychology and psychiatry, an area most noteworthy. Furthermore, the importance of the preservation of boundaries between scientific disciplines is emphasized as a key prequirement for a successful dialogueἩ ἐργασία ἀσχολεῖται μέ τή σχέση τῆς ψυχικῆς ὑγείας μέ τήν ποιμαντική διακονία τῆς Ἐκκλησίας.

Political parties do not merely reflect social divisions, they actively construct them. While this point has been alluded to in the literature, surprisingly little attempt has been made to systematically elaborate the relationship between parties and the social, which tend to be treated as separate domains contained by the disciplinary division of labor between political science and sociology. This article demonstrates the constructive role of parties in forging critical social blocs in three separate cases, India, Turkey, and the United States, (...) offering a critique of the dominant approach to party politics that tends to underplay the autonomous role of parties in explaining the preferences, social cleavages, or epochal socioeconomic transformations of a given community. Our thesis, drawing on the work of Gramsci, Althusser, and Laclau, is that parties perform crucial articulating functions in the creation and reproduction of social cleavages. Our comparative analysis of the Republican and Democratic parties in the United States, Islamic and secularist parties in Turkey, and the Bharatiya Janata Party and Congress parties in India will demonstrate how “political articulation” has naturalized class, ethnic, religious, and racial formations as a basis of social division and hegemony. Our conclusion is that the process of articulation must be brought to the center of political sociology, simultaneously encompassing the study of social movements and structural change, which have constituted the orienting poles of the discipline.

The main purpose of this article is to broaden U.S. scholars' awareness of the similarities and differences of gender literature in another part of the world. In providing this partial review of gender scholarship in India, the authors hope to foster critical reflection on the inequities of global knowledge production and consumption and the role of U.S. academic institutions and scholars in this project. The article is written not by scholars who are based in India but by those who are (...) based in U.S. academies. Given their location, linguistic and cultural competencies, and scholarly expertise, the review, at best, can be described as a glimpse of gender scholarship in India. The four sections of this article feature theoretical and methodological issues, the women's movement, and violence against women in India. (shrink)

There is considerable evidence that language comprehenders derive lexical-semantic meaning by mentally simulating perceptual and motor attributes of described events. However, the nature of these simulations—including the level of detail that is incorporated and contexts under which simulations occur—is not well understood. Here, we examine the effects of first- versus third-person perspective on mental simulations during sentence comprehension. First-person sentences describing physical transfer towards or away from the body modulated response latencies when responses were made along a front-back axis, consistent (...) with the action-sentence compatibility effect. This effect was not observed for third-person sentences. The ACE was observed when making responses along a left-right axis for third-person, but not first-person sentences.sentences did not show an ACE along either axis. These results show that perspective is a detail that is simulated during action sentence comprehension, and that motoric activations are flexible and affected by the pronominal perspective used in the sentence.

At present there is an enormous discrepancy between our nanotechnological capabilities (particularly our nanobiotechnologies), our social wisdom, and consensus on how to apply them. To date, cost considerations have greatly constrained our application of nanotechnologies. However, novel advances in microsystem platform technologies are about to greatly diminish that economic constraint while developing new industries. Properly used in a solid legal and ethical framework, within an educated population, these advances will vastly enrich our quality of life without being intrusive. Improperly used, (...) these technologies could lead to a modern-day Luddism, social turmoil, or possibly even to emulating those societies described in the darkest of novels. These technologies must be developed in tandem with the social and legal frameworks needed to ensure that they improve both individuals and our society. To ensure that this occurs, we need to have the ethical, legal, scientific, and engineering experts working together and with the public. (shrink)

The application of in vivo genetic lineage tracing has advanced our understanding of cellular mechanisms for tissue renewal in organs with slow turnover, like the lung. These studies have identified an adult stem cell with very different properties than classically understood ones that maintain continuously cycling tissues such as the intestine. A portrait has emerged of an ensemble of cellular programs that replenish the cells that line the gas exchange (alveolar) surface, enabling a response tailored to the extent of cell (...) loss. A capacity for differentiated cells to undergo direct lineage transitions allows for local restoration of proper cell balance at sites of injury. We present these recent findings as a paradigm for how a relatively quiescent tissue compartment can maintain homeostasis throughout a lifetime punctuated by injuries ranging from mild to life‐threatening, and discuss how dysfunction or insufficiency of alveolar repair programs produce serious health consequences like cancer and fibrosis.

AbstractIn her article from 2019, Fleur Johns describes a change: from a style of development work marked by a propensity for ‘planning’, to one marked by a propensity for ‘prototyping’. Our project in this paper is to propose a modest shift in perspective. Where Johns traces a transition from old to new styles, we emphasise the enduring links between planning and prototyping, such that both styles are best understood through their ongoing relationships and entanglements. Returning to Pulse Lab Jakarta (PLJ), (...) the site of Johns’ initial inquiry, we offer a reinterpretation of what might be novel about PLJ for development practice. Our claim is that to understand the particular intervention that PLJ represents, and the new modes of practice it produces, it may be helpful to understand PLJ's work in the manner of a ‘modular’ attachment to existing development apparatuses, that combines big data analytics with design thinking. We then develop some reflections and speculations on the forms and novelty of PLJ in light of our redescription of its work in the language of modularity. (shrink)

This essay responds to Donna J. Haraway's (2016) provocation to ‘stay with the trouble’ of learning to live well with nonhumans as kin, through practice-based approaches to learning to care for nonhuman others. The cases examine the promotion of care for trees through mobile game apps for forest conservation, and kinship relations with city farm animals in Kentish Town, London. The cases are analysed with a view to how they articulate care practices as a means of making kin. Two concepts (...) are proposed, ‘learning from’ and ‘facing’ the Other, which are thickened through discussions of how caring takes place in each case in relation to a particular category of nonhuman other: animated tree and urban farm animal. Thus while attendant to situations of care involving a specific nonhuman subject, the cases also broker thinking on learning from and facing (the) other kinds of trees and animals, and the interspecies dynamics of which they are a part. The intersectional implications of the practice sites and participants are elaborated, to complexify and affirm situated but also reflexive approaches to caring. In doing this, the authors attend to their own positionalities, seeking to diversify Western-based ecofeminist engagements with caring, while asking what their research can do for the nonhuman other. They formulate and apply a collaborative methodological approach to the case studies, developed through cultivating attentiveness to the nonhuman subject of research. The authors consider in particular how attentiveness to the nonhuman other can facilitate practices of knowing that further a non-anthropocentric and non-innocent ethic of caring. By further interconnecting situations of caring for nonhuman animals and plants, the authors advocate for practices of care that antagonise how species boundaries are drawn and explore the implications for learning to care for nonhumans as kin.

ABSTRACT The emergence of the coronavirus disease 2019 pandemic has wide-ranging implications for the field of professional psychology. As clinical practice has rapidly adapted to ensure continuity of care, doctoral students have encountered unique opportunities for ethics-related competency development across practicum training settings. This article discusses the relevant American Psychological Association Ethics Code standards and additional ethical considerations facing trainees as they navigate their foundational clinical experiences and develop as professional psychologists in light of a pandemic.

There is considerable evidence that language comprehenders derive lexical‐semantic meaning by mentally simulating perceptual and motor attributes of described events. However, the nature of these simulations—including the level of detail that is incorporated and contexts under which simulations occur—is not well understood. Here, we examine the effects of first‐ versus third‐person perspective on mental simulations during sentence comprehension. First‐person sentences describing physical transfer towards or away from the body (e.g., “You threw the microphone,” “You caught the microphone”) modulated response latencies (...) when responses were made along a front‐back axis, consistent with the action‐sentence compatibility effect (ACE). This effect was not observed for third‐person sentences (“He threw the microphone,” “He caught the microphone”). The ACE was observed when making responses along a left‐right axis for third‐person, but not first‐person sentences. Abstract sentences (e.g., “He heard the message”) did not show an ACE along either axis. These results show that perspective is a detail that is simulated during action sentence comprehension, and that motoric activations are flexible and affected by the pronominal perspective used in the sentence.

We identified nearly 180 Black women who earned medical degrees prior to the start of the Second World War and found information regarding their family and social connections, premedical and medical educations, and internship experience or lack thereof for many of these women. Through their collective history, we observed large-scale trends, especially regarding the importance of “separatist” medical education and declining medical school attendance among African American women in the 1910s as medicine became an increasingly exclusionary profession. While our research (...) uncovered trends specific to Black women physicians, the implications of our research can be applied far more widely to other historically marginalized scientific practitioners. This research reminds us of the longstanding and shifting presence of Black women in science and medicine, despite the enduring popular belief that white men represent who participates in science, both historically and today.

The modern abundance and prominence of data has led to the development of “data science” as a new field of enquiry, along with a body of epistemological reflections upon its foundations, methods, and consequences. This article provides a systematic analysis and critical review of significant open problems and debates in the epistemology of data science. We propose a partition of the epistemology of data science into the following five domains: (i) the constitution of data science; (ii) the kind of enquiry (...) that it identifies; (iii) the kinds of knowledge that data science generates; (iv) the nature and epistemological significance of “black box” problems; and (v) the relationship between data science and the philosophy of science more generally.

Modern Indian nationalist thought has dealt with political ideas such as freedom, equality, liberty, democracy, so on and so forth. The idea of freedom received enough attention on the part of most of the modern Indian political thinkers. However, the idea of freedom as envisaged by the nationalist thinkers did not receive positive response from the other stream of modern Indian thought. Dalit-Bahujan political thinkers questioned the narration of freedom as propagated by the nationalist thinkers. Nationalist thinkers aspired for universal (...) values and at the same time reaffirmed ancient religious principles. Such effort was questioned and doubted by the other thinkers of modern India. Thus, one can find different narrations of freedom, such as social, economic and political. The social categories such as caste, class and gender became bases for their narration on the idea of freedom. The ideas and arguments of B. G. Tilak, M. K. Gandhi, Pandita Ramabai, Jyotiba Phule, B. R. Ambedkar E. M. S. Namboodripad and others would help in larger understanding of the idea of freedom. (shrink)

A dual identity organization refers to an organization having two, often mutually conflicting, self-referential definitions of ‘who we are’ as an organization. Values practices are defined as ‘the sayings and doings in organizations that articulate and accomplish what is normatively right or wrong, good or bad, for its own sake’. In this paper, I study influence of values practices on sustenance of an organizational identity in dual-identity organizations.I adopted a qualitative approach and single case study method for providing a rich (...) narrative of the phenomenon. I collected data from an Indian software organization involved in both software services and software products businesses.The case data show that values practices manifested inside dual-identity organizations in the form of comparisons of the two identities by internal audiences. The study identifies three types of distinct, but interrelated, values practices: values infusion, collective perceptions of pragmatic alignment and collective expectations of equality and equity. The case data show that ineffective management of these values practices was detrimental to the sustenance of an organizational identity that failed to perform well on conventional performance parameters.

Medical ethics in the Indian context is closely related to indigenous classical and folk traditions. This article traces the history of Indian conceptions of ethics and medicine, with an emphasis on the Hindu tradition. Classical Ayurvedic texts including Carakasamhita and Susrutasamhita provide foundational assumptions about the body, the self, and gunas, which provide the underpinnings for the ethical system. Karma, the notion that every action has consequences, provides a foundation for medical morality. Conception, prolongation of one's blood-line is an important (...) ethical aim of life. Thus a wide range of practices to further conception are acceptable. Abortion is a more complex matter ethically. At the end of life death is viewed in the context of passage to another life. Death is a relief from suffering to be coped with by the thought of an eternal atman or rebirth. Keywords: India, Hindu, karma, conception, death CiteULike Connotea Del.icio.us What's this? (shrink)

With the technological evolutionary advent, a vision-based approach presents the remote measuring approach for the analysis of vibration. The structure vibration test and model parameter identification in the detection of the structure of the bridge evaluation occupies the important position. The bridge structure to operate safely and reliably is ensured, according to the geological data of qixiashan lead-zinc mine and engineering actual situation, with the aid of international mining software Surpac. To build the 3D visualization model of the application of (...) visualization in mine production are discussed. The results show that the final solid model of -425 stope can accurately display the spatial form of each layer of stope through rotation, amplification and movement. The proposed system is effectually able to perform cutting, volume calculation and roaming in any direction, which has certain guiding significance for mine production management. An accuracy value of 98.75%, the sensitivity of 99%, specificity of 99.64% and PPV of 99.89% are achieved using the proposed 3D modelling and visualization algorithm for vibration signal processing and management.
