One Definition to Join Them All: The N-Spherical Solution for the EEG Lead Field
No full textAlbeit its simplicity, the concentric spheres head model is widely used in EEG. The reason behind this is its simple mathematical definition, which allows for the calculation of lead fields with negligible computational cost, for example, for iterative approaches. Nevertheless, the literature shows contradictory formulations for the electrical solution of this head model. In this work, we study several different definitions for the electrical lead field of a four concentric spheres conduction model, finding that their results are contradictory. A thorough exploration of the mathematics used to build these formulations, provided in the original works, allowed for the identification of errors in some of the formulae, which proved to be the reason for the discrepancies. Moreover, this mathematical review revealed the iterative nature of some of these formulations, which allowed us to develop a formulation to solve the lead field in a head model built from an arbitrary number of concentric, homogeneous, and isotropic spheres
How Technological Knowledge Management Capability Compliments Knowledge-Intensive HRM Practices to Enhance Team Outcomes: A Moderated Mediation.
No full textAlthough research establishes a link between knowledge-intensive human resource (HR) practices (KIHRP) and knowledge-intensive team (KIT) performance, knowledge is limited about the underlying mechanisms and boundary conditions that determine this relationship. This study integrates the ability–motivation–opportunity (AMO) framework and theory of team adaptation into an information processing perspective to present a cohesive model that explains the mediating role of team knowledge sharing and reflexivity processes, and moderation of organization's technological knowledge management (KM) capability to explain the effect of KIHRP on KIT performance. Data were collected in three waves and from three sources consisting of 380 knowledge workers from 123 teams in 74 organizations in Pakistan. The findings indicate that KIHRP relates positively to KIT performance directly as well as via team knowledge sharing and reflexivity processes where the organization's technological KM capability further strengthens this relationship
Designing for All: The Gender Perspective in the space of the Greek City
No full textOver the last twenty years, there has been a growing global focus on gender equality, which is considered a significant step forward. With the integration of gender equality into the United Nations' Sustainable Development Goals, various international organizations have advocated the identification of strategies in different sectors to gradually achieve human rights and gender equality for all women and girls. Cities have emerged as places that offer opportunities for women's empowerment through work, education, and networking.The dominant discourse on gender, whether centered around the binary of male/female or extended to other gender identities, has triggered broader discussions and actions towards equality. However, despite these positive steps, it has not eradicated inequalities in areas such as employment, healthcare, leadership positions, housing, and unpaid labor. Conversely, urban spaces, designed predominantly through male-centered models, can still perpetuate inequalities. This raises questions about whether gender equality will remain an elusive goal.In Greece, despite legal provisions for gender equality, there are many aspects of life where gender issues are marginalized, and discrimination and inequalities persist. Local governments have recently incorporated gender policies to align with international standards and seek funding, but challenges remain due to the lack of comprehensive gender-related data. The COVID-19 pandemic and lockdown have brought new considerations to urban space, infrastructure, mobility, services, and gender inequalities. Within this context, the report explores feminist urban planning and the way it emphasizes the importance of gender-responsive urban design that caters to the needs, expectations, and desires of women and other subjectivities, acknowledging their contributions in shaping urban spaces and the obligation of the urban realm to include all its residences and users.The report aims to present a comprehensive view of the intersection between the city and gender, encompassing various scales, from governance and national policies to everyday life. It underscores the need for inclusive participation, considering diverse social groups, and collecting and processing gender-disaggregated data. By doing so, urban spaces can become sites of transformation, benefitting all individuals and fostering social change toward gender equality. The report also provides examples of initiatives from a variety of countries that can serve as inspiration and starting points for change. Ultimately, it emphasizes that the visions of the inclusive city and the city of care should not remain utopian ideals but should be translated into action. Participatory tools not only provide decision-makers with data but also empower city residents to envision and claim their right to the city

The Patient-Perceived Helpfulness of Measures Scale:Development and Validation of a Scale to Assess the Helpfulness of Using Measures in Psychological Treatment
No full textIn response to the increase in Routine Outcome Monitoring and Clinical Feedback, the Patient-Perceived Helpfulness of Measures Scale (ppHMS) was developed to assess the helpfulness-as perceived by patients-of using measures in psychological treatment. Study 1: The construct of patient-perceived helpfulness of measures was explored using thematic analysis with 15 patients. Six helpful and three unhelpful themes were identified and informed item development. Study 2: 28 items were formulated and rated by experts. Ten items were taken forward for psychometric shortening in a sample of 76 patients. Confirmatory factor analysis (CFA) led to an adequately fitting six-item model with excellent internal consistency, and convergence with the Delighted-Terrible single item of product satisfaction and a single item of measure helpfulness. Study 3: In a stratified online sample of 514 U.K. psychotherapy patients, a five-item model constituted the best fit. The final ppHMS had excellent internal consistency (McDonald's ω = .90), convergent validity with psychotherapy satisfaction ( r = .5; p < .001), divergence from social desirability ( r = .1), and metric and scalar invariance across measures. Study 4: Analyses were replicated and confirmed in a stratified U.S. sample ( n = 602). The ppHMS is a reliable and valid scale that can be used to assess and compare patients' perceptions of the helpfulness of different measures as part of their psychological treatment. </p

Historians, Emotions, and Children’s Trauma in the Archives
No full textThis reflective essay focuses on the emotionality of children’s creations in the archives, particularly where children’s creations give insight into traumatic histories. I argue that history will be better placed when historians write more openly about the inherently distressing nature of the materials they consume. It is impossible to be unaffected by such material and acknowledging this will make our work more transparent by outlining to readers the context it was written in. The complex, emotive interpretive task historians face is demonstrated using two children’s drawings—one from the Spanish Civil War and the other from the Darfur Genocide
“Denomination Doesn’t Matter”? A Proposal for a Receptive Ecumenical Missiology from a Theological Action Research Project on Methodists and Catholics Engaging Together in Social Action
Get PDFIn ecumenical social action and mission it is common to hear phrases like, ‘denomination doesn’t matter’, and ‘we are all just Christians’. This reflects a wider tension with modern ecumenism between doctrinal and practice-based approaches to ecumenism. In this theological action research project on Methodists and Catholics engaging together in social action many espoused this pragmatic approach to action over ecclesial tradition. However, in practice they engaged with the complexities of ecumenical life and ecclesial tradition, many in significant ways. Drawing on the themes of receptivity, identity and practical wisdom seen in their practice and their understanding of ecumenism as something which is ‘lived’ rather than ‘done’, I offer a receptive ecumenical missiology. This ecumenical missiology, based in a pneumatological receptivity, offers an integrated way forward, overcoming many of the tensions between practice, mission and doctrine felt within modern ecumenism
