Multiple Graphs and Low-Rank Embedding for Multi-Source Heterogeneous Domain Adaptation

Multi-source domain adaptation is a challenging topic in transfer learning, especially when the data of each domain are represented by different kinds of features, i.e., Multi-source Heterogeneous Domain Adaptation (MHDA). It is important to take advantage of the knowledge extracted from multiple sources as well as bridge the heterogeneous spaces for handling the MHDA paradigm. This article proposes a novel method named Multiple Graphs and Low-rank Embedding (MGLE), which models the local structure information of multiple domains using multiple graphs and learns the low-rank embedding of the target domain. Then, MGLE augments the learned embedding with the original target data. Specifically, we introduce the modules of both domain discrepancy and domain relevance into the multiple graphs and low-rank embedding learning procedure. Subsequently, we develop an iterative optimization algorithm to solve the resulting problem. We evaluate the effectiveness of the proposed method on several real-world datasets. Promising results show that the performance of MGLE is better than that of the baseline methods in terms of several metrics, such as AUC, MAE, accuracy, precision, F1 score, and MCC, demonstrating the effectiveness of the proposed method.

Abstract: The beginnings of corporal expression have been and are being analyzed from different perspectives. This work has attempted to delve into the beginnings that occurred throughout the 20th century, when this emerging discipline was nourished by multiple sources: society, arts, education, psychology, etc. Patricia Stokoe (1919-1996), devoted her life to the study of body language-dance. Considered one of the initiators in this field (Kalmar, 2005; Cardona, 2009; Ruano & Sánchez, 2009), her work continues to be a reference nowadays and it is present in a large part of the scientific production generated in this discipline. It is in the research by Cardona (2009), who carried out a doctoral thesis, where the study of the life and work of the author has been deepened. We present here how this qualitative research was carried out. A cross-sectional descriptive treatment was carried out, using the analysis of documents and interviews. We conducted more than thirty interviews between Buenos Aires and Spain, establishing 4 dimensions / fields that provided structure and clarity to the study: life analysis; analysis of the influences on life and work; analysis of the work; bibliographic essay of the work. We obtained results that make the life and work of Patricia Stokoe one of the pioneers in the construction and genesis of corporal expression.

Differential effects of rude coworkers and patients on nurses' safety performance: an emotional labor perspective

PurposeThis paper examines how nurses differentially respond, both emotionally and behaviorally, to incivility from coworkers (i.e. other healthcare staff) and from their patients. Specifically, the authors explore how coworker and patient incivility distinctly influence the extent to which nurses engage in emotional labor, which in turn, may impact nurses' safety performance. The authors further examine how nurses' hostile attribution biases exacerbate and mitigate these effects.Design/methodology/approachA three-week longitudinal study was conducted with 187 nurses in which they reported their experiences with incivility, surface and deep acting, hostile attribution biases and safety performance (i.e. safety compliance and participation).FindingsPatient incivility led to more surface acting across all nurses. Further, the effects of coworker incivility on emotional labor strategies were conditional on nurses' hostile attribution biases (HAB). Specifically, coworker incivility led to more surface acting among nurses higher on HAB, and coworker incivility led to less deep acting among those lower on HAB. Finally, surface acting was associated with reduced safety participation, and deep acting was associated with greater safety compliance and safety participation.Originality/valueThe nursing context allowed the current research to extend understanding about how incivility affects an unexplored outcome—safety performance. The current research also offers a rare examination of the effects of incivility from multiple sources (i.e. coworkers and patients) and demonstrates the different processes through which incivility from these different sources impacts nurses' ability to perform safely.

Step, Error, and Event Frameworks in Endovascular Aortic Repair

Objective: Competency-based surgical education requires detailed and actionable feedback to ensure adequate and efficient skill development. Comprehensive operative capture systems such as the Operating Room Black Box (ORBB; Surgical Safety Technologies, Inc), which continuously records and synchronizes multiple sources of intraoperative data, have recently been integrated into hybrid rooms to provide targeted feedback to endovascular teams. The objective of this study is to develop step, error, and event frameworks to evaluate technical performance in elective endovascular aortic repair (EVAR) comprehensively captured by the ORBB (Surgical Safety Technologies, Inc; Toronto, Canada). Methods: This study is based upon a modified Delphi consensus process to create evaluation frameworks for steps, errors, and events in EVAR. International experts from Vascular Surgery and Interventional Radiology were identified, based on their records of publications and invited presentations, or serving on relevant journal editorial boards. In an initial open-ended survey round, experts were asked to volunteer a comprehensive list of steps, errors, and events for a standard EVAR of an infrarenal aorto-iliac aneurysm (AAA). In subsequent survey rounds, the identified items were presented to the expert panel to rate on a 5-point Likert scale. Delphi survey rounds were repeated until the process reached consensus with a predefined agreement threshold (Cronbach α>0.7). The final frameworks were constructed with items achieving an agreement (responses of 4 or 5) from greater than 70% of experts. Results: Of 98 invited proceduralists, 38 formed the expert consensus panel (39%), consisting of 29 vascular surgeons and 9 interventional radiologists, with 34% from North America and 66% from Europe. Consensus criteria were met following the third round of the Delphi consensus process (Cronbach α=0.82–0.93). There were 15, 32, and 25 items in the error, step, and event frameworks, respectively (within-item agreement=74%–100%). Conclusion: A detailed evaluation tool for the procedural steps, errors, and events in infrarenal EVAR was developed. This tool will be validated on recorded procedures in future work: It may focus skill development on common errors and hazardous steps. This tool might be used to provide high-quality feedback on technical performance of trainees and experienced surgeons alike, thus promoting surgical mastery.

Fracture Geometry Calibration Using Multiple Surveillance Techniques

An accurate Mechanical Earth Model (MEM) is of vital importance in tight gas reservoirs where hydraulic fracturing is the only way to produce hydrocarbons economically. The Barik tight gas reservoir is the main target in Khazzan and Ghazeer Fields at the Sultanate of Oman (Rylance et al., 2011). This reservoir consists of multiple low-permeability sandstone layers interbedded with marine shales. A good understanding of the fracture propagation in such a reservoir has a major effect on completion and fracturing design. The MEM derived from sonic logs and calibrated with core data needs to be further validated by independent measurements of the fracturing geometry. Multiple surveillance techniques have been implemented in the Barik reservoir to validate the MEM and to match observations from hydraulic fracturing operations. These techniques include closure interpretation using a wireline deployed formation testing assembly, the use of mini-frac injection tests with deployed bottomhole pressure gauges, execution of post injection time-lapse temperature logging, the injection of radioactive tracers, associated production logging, subsequent pressure transient analysis and other techniques. A cross-disciplinary team worked with multiple sources of data to calibrate the MEM with the purpose of delivering a high-confidence prediction of the created fracture geometry, which honors all available surveillance data. In turn, this validation approach provided a solid basis for optimization of the completion and fracturing design, in order to optimally exploit this challenging reservoir and maximize the economic returns being delivered. For example, combination of stress testing with radioactive tracers provided confidence in stress barriers in this multilayered reservoir. Pressure transient analysis allowed to calibrate mechanical model to match fracturing half-length that is contributing to production. This paper provides extensive surveillance examples and workflows for data analysis. Surveillance of this degree in the same well is uncommon because of the associated time and cost. However, it provides unique value for understanding the target reservoir. This paper demonstrates the Value Of Information (VOI) that can be associated with such surveillance and provides a concrete and practical example that can be used for the justification of future surveillance programs associated with the hydraulic fracturing operations.

Dying at work. Work-related suicide – how does the UK regulatory context measure up?

Purpose The purpose of this paper is to examine how work-related suicides are monitored, investigated and regulated in the UK, examining a small selection of cases and drawing on international comparison with other countries. Effective data collection and regulation are the cornerstone of suicide prevention, and this paper aims to consider whether the UK’s current regulatory framework provides an effective basis for preventing work-related suicides. Design/methodology/approach This study draws on qualitative sociological methods and is based on an in-depth analysis of 12 suicide cases occurring between 2015 and 2020. In each case, work-related causal factors had been previously identified by at least one official source (police enquiry, coroner or employer’s investigation). This study analysed multiple sources of documentation and undertook interviews with individuals close to each suicide case. The aim of this study was to consider the organisational response of three stakeholder organisations to the suicides: the Health and Safety Executive (HSE), the coroner and the employer. Findings The study points to serious shortcomings in the UK’s regulatory response to work-related suicides. Suicides are currently not recorded, investigated or regulated. Whereas the fracture of an arm or leg in the workplace needs to be reported to the HSE for further investigation, a suicide occurring in the workplace or that is work-related does not need to be reported to any public agency. Employers are not required to investigate an employee suicide or make any changes to workplace policies and practices in the aftermath of a suicide. The work-related factors that may have caused one suicide may, therefore, continue to pose health and safety risks to other employees. Originality/value Whereas some recent studies have examined work-related suicides within specific occupations in the UK, to the best of the authors’ knowledge, this is the first study to analyse the UK’s regulatory framework for work-related suicides. The study on which the paper is based produced a set of recommendations that were targeted at key stakeholder organisations.

Measuring Impartial Beneficence: A Kantian Perspective on the Oxford Utilitarianism Scale

To capture genuine utilitarian tendencies, (Kahane et al., Psychological Review 125:131, 2018) developed the Oxford Utilitarianism Scale (OUS) based on two subscales, which measure the commitment to impartial beneficence and the willingness to cause harm for the greater good. In this article, I argue that the impartial beneficence subscale, which breaks ground with previous research on utilitarian moral psychology, does not distinctively measure utilitarian moral judgment. I argue that Kantian ethics captures the all-encompassing impartial concern for the well-being of all human beings. The Oxford Utilitarianism Scale draws, in fact, a point of division that places Kantian and utilitarian theories on the same track. I suggest that the impartial beneficence subscale needs to be significantly revised in order to capture distinctively utilitarian judgments. Additionally, I propose that psychological research should focus on exploring multiple sources of the phenomenon of impartial beneficence without categorizing it as exclusively utilitarian.

Genome-wide SNPs of vegetable leafminer, Liriomyza sativae: insights into the recent Australian invasion

Liriomyza sativae, the vegetable leafminer, is a serious agricultural pest originally from the Americas which has now colonized all continents except Antarctica. In 2015, L. sativae arrived on the Australian mainland and established on the Cape York Peninsula in the northeast of the country. Here, we assessed genetic variation in L. sativae based on genome-wide single nucleotide polymorphisms (SNPs) generated by double-digest restriction-site associated DNA sequencing (ddRAD-seq) to uncover the potential origin(s) of this pest in Australia and contribute to reconstructing its global invasion history. Our principal component analyses (PCA) results suggested that Australian mainland populations were genetically close to populations from the Torres Strait and had connections to Bali and Papua New Guinea (PNG), whereas populations from Asia and Africa were more distantly related. Hawaii was genetically distinct from populations from Asia, Africa and Australia. Co-ancestry analyses pointed to signals of gene flow from the Torres Strait into the Australian mainland, while Indonesia/PNG were the likely sources of the initial invasion into the Torres Strait. Admixture analyses further revealed that L. sativae from the Torres Strait had genetic diversity originating from multiple sources, which has now spread to the Australian mainland. The L. sativae lineages from Asia/Africa appear closely related and may share co-ancestry. Isolation by distance (IBD) was found at a broad global scale, but not within small regions, suggesting human-mediated factors contribute to the local spread of this pest. Overall, our findings highlight the challenges in quarantine measures aimed at restricting the distribution of this global pest.

A method for defining the CORE of a psychosocial intervention to guide adaptation in practice: Reciprocal imitation teaching as a case example

Defining the central components of an intervention is critical for balancing fidelity with flexible implementation in both research settings and community practice. Implementation scientists distinguish an intervention’s essential components (thought to cause clinical change) and adaptable periphery (recommended, but not necessary). While implementing core components with fidelity may be essential for effectiveness, requiring fidelity to the adaptable periphery may stifle innovation critical for personalizing care and achieving successful community implementation. No systematic method exists for defining essential components a priori. We present the CORE (COmponents & Rationales for Effectiveness) Fidelity Method—a novel method for defining key components of evidence-based interventions—and apply it to a case example of reciprocal imitation teaching, a parent-implemented social communication intervention. The CORE Fidelity Method involves three steps: (1) gathering information from published and unpublished materials; (2) synthesizing information, including empirical and hypothesized causal explanations of component effectiveness; and (3) drafting a CORE model and ensuring its ongoing use in implementation efforts. Benefits of this method include: (1) ensuring alignment between intervention and fidelity materials; (2) clarifying the scope of the adaptable periphery to optimize implementation; and (3) hypothesizing—and later, empirically validating—the intervention’s active ingredients and their associated mechanisms of change. Lay abstract Interventions that support social communication include several “components,” or parts (e.g. strategies for working with children and families, targeting specific skills). Some of these components may be essential for the intervention to work, while others may be recommended or viewed as helpful but not necessary for the intervention to work. “Recommended” components are often described as “adaptable” because they can be changed to improve fit in different settings where interventions are offered or with different individuals. We need to understand which parts of an intervention are essential (and which are adaptable) when translating interventions from research to community settings, but it is challenging to do this before studying an intervention in the community. This article presents the CORE (COmponents & Rationales for Effectiveness) Fidelity Method—a new method for defining the essential components of evidence-based interventions—and applies it to a case example of Reciprocal Imitation Teaching, an intervention that parents are taught to deliver with their young children with social communication delays. The CORE Fidelity Method involves three steps: (1) gathering information from multiple sources; (2) integrating information from previous research and theory; and (3) drafting a CORE model for ongoing use. The benefits of using the CORE Fidelity Method may include: (1) improving consistency in intervention and research materials to help all providers emphasize the most important skills or strategies; (2) clarifying which parts of the intervention can be adapted; and (3) supporting future research that evaluates which intervention components work and how they work.
