A Common Grounded Voltage Quadrupler ASL/PSC Hybrid Converter With Reduced Voltage Stress

Active switched inductor (ASL) dc-dc converters have very high step-up voltage gain but practically they suffer from high voltage stress across switches because of the resonance caused by the mismatch among the inductor values and switch parameters. This paper presents a new hybrid dc-dc converter topology derived from ASL and passive switched capacitors (PSC). The proposed topology has high step up voltage gain over wide range of duty cycle. The resonance due to mismatch of parameters is eliminated. The proposed converter has low voltage stress, low current stress on circuit elements and common ground between input and output ports. The circuit configuration, operating principle and steady state analysis of the proposed converter are presented. The key performance parameters are compared with that of other high-gain dc-dc converters. A 300W laboratory prototype is developed and experimental verification is carried out for the voltage step-up from 30V to 400V. The closed-loop operation is also verified experimentally and results are presented.

Synchronous Dual-Switch Ultrahigh Step-Up DC–DC Converter Based on Coupled Inductor and Voltage Multiplier for Photovoltaic Systems

In this article, an ultrahigh step-up quadratic boost converter is proposed for photovoltaic systems. By integrating with a coupled inductor and a voltage multiplier, the voltage gain can be improved significantly without high turns ratio and the voltage stress across the power switches are alleviated. Thus, low on-resistance of the power switches are available to enhance efficiency. Common ground structure of quadratic boost and synchronous operation of the two switches facilitate the control. Also, the continuous input current promotes the maximum power point tracking (MPPT). Detailed description of the operation principles and steady-state analysis of this converter in CCM and DCM are presented. A 250W rated laboratory prototype is fabricated and verified, demonstrating a maximum efficiency of 96.5%. Moreover, the dynamic response is tested to prove the stability of the proposed converter. Finally, a simulation is built to evaluate the feasibility of MPPT function.

The Geoeconomic Turn of the Single European Market? Conceptual Challenges and Empirical Trends

AbstractThe nature of global economic interactions is undergoing profound changes. Rising concerns over the security and strategic implications of economic interdependence are leading to what is often defined as a ‘geoeconomic world order’. In framing this Special Issue, this article sets a common conceptual ground to assess whether, how and why the single European market is experiencing such a geoeconomic turn and how EU responses are shaping other international actors in the process. It develops a research agenda to examine (i) the systemic pressures pushing towards geoeconomic responses, (ii) the internal drivers and processes determining the nature of the EU's geoeconomic turn (what we term ‘shades of geopoliticisation’) and (iii) the external consequences of the EU's embrace of geoeconomics. The analytical discussion is complemented by an overview of empirical trends, drawing examples from the various fields of market integration and European policy‐making covered in the contributions to this Special Issue.

Religious Moderation: An Analysis of Understanding, Internet and Social Media Exposure and Social Interaction Systems

<p><strong>Introduction:</strong> Religious moderation is launched because it concerns the order of life of the nation and state, where the internet and social media become a platform for any dynamic public discussion and change perspectives and practices in religious harmony. This study examines access to information about religious moderation through the internet and social media (WhatsApp, Instagram, Facebook, Twitter, Line) as the most widely used platforms in Indonesia and the influence of exposure to its content on understanding and the system of relational interaction among university students.</p><p><strong>Methods:</strong> Explanatory quantitative survey method with factor and regression analysis to explain the dominant factors and the magnitude of the influence of exposure to religious moderation content on students' understanding and interpersonal relationships.</p><p><strong>Findings:</strong> That student quite often access information about religious moderation on social media through WhatsApp and Instagram. Issues related to national commitment, tolerance, intolerance, violence, radicalism, government attitudes, regulations and their consequences, correlate with the dogmatism factor. The findings show that it is not easy to change one's religious beliefs, and this should be respected. So what remains is to find common ground and give a positive impression so that social interactions continue to run normally.</p><p class="normal"><strong>Originality:</strong> The research presents a novelty in the perspective of communication science on the understanding of religious moderation and its correlation with the interpersonal interaction system in students from non-religious campuses. Where previously religious moderation was widely studied in the perspective of language, civilization, humanity, culture, education and with subjects from religious campuses, especially Islam.</p>

Die öffentliche Aushandlung von Expertise: Wissenschaftsblogs als Ort eristischer Verständigung? Exploratorischer Einstieg in ein Forschungsprojekt

Abstract In this paper, we present a joint research project on communication practices in science blogs that focuses on the negotiation of expertise against the background of potentially divergent expectations of the participants. The object of analysis are the blogposts and comments of the blog portal “SciLogs – Tagebücher der Wissenschaft” (maintained by Spektrum-Verlag since 2000), which will be examined for patterns of language and argumentation using both corpus linguistic and hermeneutic methods of analysis. First explorative approaches, as we present them here in form of a first glimpse on tri-grams, their frequencies and their context, indicate, that – despite the sometimes heated debates – a largely politely conducted communication (distance communication), constructing a kind of stylistic common ground, take place about what is usual, good and right “in der Wissenschaft” [in science] from the different perspectives meeting here and who is (or is not) “in der Lage” [able] to follow the scientific argumentations or to contribute to them constructively.

The Perception of Pain and Suffering of the Weak, the Innocent and the Marginalized from Evolution and from Christian Theology

The topic of pain and suffering is complex and requires a holistic vision. This article begins by clarifying concepts to understand pain as a biological, psychological, and social phenomenon that has an evolutionary history whose maximum expression arises in humans. Established this common ground, it explores altruism and animal cooperation as incipient phenomena of care for the other, though contextual. Then it points out that the difference with humans is that they perceive caring for the weak, innocent, and marginalized as a moral duty and a path of personal flourishing. Finally, in the face of human weakness and from Christian theology, God shows with deeds a path of care for the weak by making himself weak, suffering and remaining innocent.

Recurrent medical imaging exposures for the care of patients: one way forward.

Medical imaging is both valuable and essential in the care of patients. Much of this imaging depends on ionizing radiation with attendant responsibilities for judicious use when performing an examination. This responsibility applies in settings of both individual as well as multiple (recurrent) imaging with associated repeated radiation exposures. In addressing the roles and responsibilities of the medical communities in the paradigm of recurrent imaging, both the International Atomic Energy Agency (IAEA) and the American Association of Physicists in Medicine (AAPM) have issued position statements, each affirmed by other organizations. The apparent difference in focus and approach has resulted in a lack of clarity and continued debate. Aiming towards a coherent approach in dealing with radiation exposure in recurrent imaging, the IAEA convened a panel of experts, the purpose of which was to identify common ground and reconcile divergent perspectives. The effort has led to clarifying recommendations for radiation exposure aspects of recurrent imaging, including the relevance of patient agency and the provider-patient covenant in clinical decision-making. CLINICAL RELEVANCE STATEMENT: An increasing awareness, generating some lack of clarity and divergence in perspectives, with patients receiving relatively high radiation doses (e.g., ≥ 100mSv) from recurrent imaging warrants a multi-stakeholder accord for the benefit of patients, providers, and the imaging community. KEY POINTS: • Recurrent medical imaging can result in an accumulation of exposures which exceeds 100 milli Sieverts. • Professional organizations have different perspectives on roles and responsibilities for recurrent imaging. • An expert panel reconciles differing perspectives for addressing radiation exposure from recurrent medical imaging.

Tilling Topoi within the Creole Garden

ABSTRACT This article reroutes the more radical tendrils of the commonplace by pursuing Christa J. Olson’s call for questioning the “terrain of rhetoric.” We ask: What if commonplaces and the commonality they entrench are not required for banding together in community? By thinking with Édouard Glissant’s Creole garden, we rework the commonplace as common place, which conceives a place that welcomes difference without requiring common ground. To articulate the possibilities of Glissant’s common place for rhetorical invention, we demonstrate its movement with examples of marronage in the southern Louisiana Territory of the United States. Marronage helps us to think how the Creole garden gathers the world’s thoughts to “illustrate the immeasurable diversity of the world,” thus founding a rhetoric that resists even as it relates to settler colonialisms and racial capitalisms (Treatise). This article demonstrates how the terrain of rhetoric may be limited by the pursuit of/for common ground.

Spontaneous perspective-taking in real-time language comprehension: evidence from eye-movements and grain of coordination

Linguistic communication requires interlocutors to consider differences in each other’s knowledge (perspective-taking). However, perspective-taking might either be spontaneous or strategic. We monitored listeners’ eye movements in a referential communication task. A virtual speaker gave temporally ambiguous instructions with scalar adjectives (“big” in “big cubic block”). Scalar adjectives assume a contrasting object (a small cubic block). We manipulated whether the contrasting object (a small triangle) for a competitor object (a big triangle) was in common ground (visible to both speaker and listener) or was occluded so it was in the listener’s privileged ground, in which case perspective-taking would allow earlier reference-resolution. We used a complex visual context with multiple objects, making strategic perspective-taking unlikely when all objects are in the listener’s referential domain. A turn-taking, puzzle-solving task manipulated whether participants could anticipate a more restricted referential domain. Pieces were either confined to a small area (requiring fine-grained coordination) or distributed across spatially distinct regions (requiring only coarse-grained coordination). Results strongly supported spontaneous perspective-taking: Although comprehension was less time-locked in the coarse-grained condition, participants in both conditions used perspective information to identify the target referent earlier when the competitor contrast was in privileged ground, even when participants believed instructions were computer-generated.

Examining Sexual Health Organizational Networks in Urban African American Communities Using Social Network Theory.

Collaboration among organizations offering sexual health and youth development services has the potential to provide youth with effective sexual health support. However, formally structured efforts (eg, coalition formation) may be impractical or unsuitable for low-income communities where resources are often already limited. Social network theories provide an alternative approach for building collaborative organizational networks. Research aims to evaluate the barriers and facilitators to collaboration in sexual health organizational networks. Organizations in low income, urban, communities in Chicago and San Francisco that serve African American adolescents. Providers (n = 22) from organizations that offer sexual health services and youth development services. Focus groups (n = 4) were conducted and analyzed utilizing a combination of coding strategies. Barriers to collaboration included resource limitations and competition, differences in organizational roles and deliverables, and prejudice and stigma. Identifying common ground among organizations was found to be a facilitator to collaboration. Social network concepts in conjunction with study findings lead to the development of a practice model that hypothesizes a pathway for organizations to improve collaboration without formally structured efforts. Our findings offer ways to encourage collaboration among organizations that support youth sexual health in low-income, urban, African American communities without relying on formal structures. Such collaborations may be critical for improving the provision of comprehensive sexual health support.

Representation of masculinities in the Arabesk films of Orhan Gencebay within the context of 1970s Turkish popular cinema (Yeşilçam)

ABSTRACT This study explores the Arabesk films of Orhan Gencebay and their representation of masculinities. It compares their approach with that of other Yeşilçam melodramas within the productive years of the Turkish popular cinema between the late 1960s and 1980, focusing on the treatment of fallen women and men’s corporeal performances in need of female approval. Gencebay’s filmography presents an opportunity to decipher an indecisive, modernized and quasi-authentic masculinity constructed upon the moral dilemmas engendered by the absence of traditional village relations in an urban setting. Although Arabesk masculinities have a generally positive attitude toward fallen women and present a milder approach to tradition, they often fall back on patriarchal modes of thought by putting the emancipation of women down to men, thus finding common ground with other masculinities prone to violence in Turkish cinema of the period.

“Bringing Sandton into Soweto”

Over the past five decades, a vast literature on gentrification has developed. Evidence of gentrification in South African cities has been recorded in historically White neighbourhoods or city districts. The presence of gentrification in peripheral, poor, traditionally Black townships has had very little (if any) consideration in the literature, and this investigation aims to address aspects of this scholarly oversight. The paper is set in the iconic South African township of Soweto. It is argued that the Vilakazi precinct in Orlando West is an example of tourism-led gentrification. The investigation unpacks the development and gentrification of the precinct and the range of tourism roles therein. The study found that residents’ experiences were mixed; some aspects of expanded leisure and services were seen positively, while forms of economic and social exclusion were also recorded following the literature on township tourism. This unique case study connects the Global North and South experience of tourism-led gentrification, arguing that much common ground between these regions is to be found.

Framing Action Through Participatory Theater: What Can We (Mis)understand for Global Crises?

ABSTRACT The present article weaves an interdisciplinary perspective into the discussion of global crises. After a brief focus on theoretical underpinnings, it argues that owing to their inherently improvisational and performative constitutions, crises can enable learning and stimulate social change. Concretely, by creating participatory theater workshops, together with individuals in migration, the initially destabilizing performative space is transformed in a common ground for collective action, thereby opening opportunities for learning and reinvention of meanings. It is through the analysis of these processes that the article offers a critical and creative commentary on the constructive role of communication for crises. Ultimately, it demonstrates that verbal misunderstandings serve as catalysts for unconventional and creative ways of expression. In turn, they promote alternative reflections and negotiations, whereby also serving as suitable response tools to employ during crises and following disruptions.

A criança com restrição verbal e o conceito de intercompreensão e multimodalidade na clínica da linguagem: um estudo de caso

ABSTRACT This article aims to analyze the process of mutual understanding from the perspective of Discursive Neurolinguistics. As a methodology, a case study was carried out on a child with a linguistic profile of verbal restriction, which concerns the dimension of utterances involving words and their morphology. Data interpretation was based on the Bakhtinian perspective, which addresses ‘understanding’ as an active-responsive process and meaning as emerging from the relationship between utterances. The results showed that the interlocutors’ common ground allowed the joint construction of meaning even in the face of verbal restrictions, and aspects such as nonverbal elements and the recognition of the child’s active-responsive role also favored mutual understanding. As a conclusion, the attention to different multimodal resources as legitimate modes of expression allows children with verbal restrictions to fulfill the role of “speakers” regardless of their modes of expression.

Synodal Process in the Dock: A Thematic Analysis of Grey Literature

This article aimed to describe the contours of the current discourse on the synodal process from the perspectives of journalists. To achieve this goal, we collected a large sample of grey literature (N= 235) from six online Catholic newspapers. The common ground unraveled by this study can lead to a fusion of horizons between the opposing sides on how and why the synodal process may allow the church to initiate needed structural reforms and create a synodal culture.

Interactions between anxiety and impulsive dimensions are differentially associated with experiential avoidance

Anxiety and impulsivity often co-occur, but due to broad conceptualizations of impulsive behavior, it remains unclear whether anxiety could be positively associated with global impulsivity or specific facets of impulsivity. Negative urgency, or rash behavior that specifically occurs during negative emotional states, may provide common ground to examine the overlap between high anxiety and high impulsivity. Limited work has examined relationships between negative urgency and behavioral processes that are often associated with both anxiety and global impulsivity, such as experiential avoidance. In this study, we examined self-report data collected from a non-clinical sample of adult participants (n = 589) to test relationships between anxiety and experiential avoidance through both negative urgency and global impulsivity. Contrary to hypotheses, we found that negative urgency alone did not alter the relationship between anxiety and experiential avoidance. However, follow-up analyses including data-driven factors of impulsivity revealed that in combination, anxiety and both emotion-based impulsivity (i.e. negative and positive urgency) and hyperactivity were linked to greater experiential avoidance. By contrast, anxiety and non-planning were associated with lower experiential avoidance. These results provide targets for future studies to examine individual differences in profiles of co-occurring anxiety and impulsivity.

A categorical approach for defining digital twins in the AECO industry

Operations and Maintenance (O&M) costs account for 60-80% of a facility’s lifecycle costs. Using Digital Twins (DTs) can aid in making O&M more effective and efficient, leading to time and cost savings. The concept of DT started in the Aerospace domain, and other industries eventually adopted it. DTs are a new concept to the Architecture, Engineering, Construction, and Operations (AECO) Industry, and there is a lot of confusion around this concept. The purpose of this paper is to provide a DT definition along with a classification structure to create a common ground for understanding DTs in the AECO industry, which leads to easier adoption of DTs. A systematic literature review was completed to identify the existing DT definitions and classification approaches. Then, through a content analysis, the core components of definitions were extracted. The identified components were used to develop a comprehensive and inclusive DT definition for the AECO industry, using the domain language. In a similar fashion, existing DT classification structures were studied, and their components were identified through content analysis. Using the identified components, a DT classification structure was proposed for the AECO industry using domain concepts and terms. The results were validated and refined through a series of semi-structured expert interviews and surveys. Interviewees and survey participants comprised DT experts from academia and industry with diverse backgrounds. The components of the proposed DT definition include virtual representation, data connection between physical and digital entities, analysis, actuation, and frequency of updates. The classification structure consisted of three DT categories, namely Digital Twin Prototype (DTP), Digital Shadow (DS), and Cyber-Physical System (CPS).

Sacraments of the Law: Discovering Common Ground of Law and Religion

Abstract This article proposes to identify ritualization—as the differentiation between the profane and the sacred—as the basic act underlying the creation of norms. In this light, we can perceive ritualization as a common ground of law and religion. This is particularly evident in ‘sacraments’, a specific type of ritual that culminates in the realization of the sacred within the profane. As ‘norm-facts’, sacraments draw the sacred into our everyday world. This connection has been evident since Roman times when ‘sacraments’ denoted performative signs of a juridico-religious nature. If one acknowledges that both religion and law draw not merely on essential ritual processes of generating normative meaning, but also use sacramental action to realize sacred norms within profane contexts, speaking of ‘law and religion’ reaches deeper than identifying the common topics of two separate spheres of the social. We have then in fact discovered an elemental and common foundation of law and religion.

Misplaced Divides? Discussing Political Disagreement With Strangers Can Be Unexpectedly Positive.

Differences of opinion between people are common in everyday life, but discussing those differences openly in conversation may be unnecessarily rare. We report three experiments (N = 1,264 U.S.-based adults) demonstrating that people's interest in discussing important but potentially divisive topics is guided by their expectations about how positively the conversation will unfold, leaving them more interested in having a conversation with someone who agrees versus disagrees with them. People's expectations about their conversations, however, were systematically miscalibrated such that people underestimated how positive these conversations would be-especially in cases of disagreement. Miscalibrated expectations stemmed from underestimating the degree of common ground that would emerge in conversation and from failing to appreciate the power of social forces in conversation that create social connection. Misunderstanding the outcomes of conversation could lead people to avoid discussing disagreements more often, creating a misplaced barrier to learning, social connection, free inquiry, and free expression.

Transcultural and Transnational Communication Principles? Suggestions for Minimum and Maximum Values as a Common Ground

ABSTRACT Based on the communication ethics of Ptahhotep and other inclusivist communication value systems, including several additional non-Western (Confucian, Buddhist, Aborigine, Cree, San, Māori, Ubuntu, and Islamic) as well as Western ones (Stoic, Christian, Kantian, socialist, liberal, and journalistic), we propose seven principles as common ground for the future regulation of media communication on a global scale. All seven are formulated in a manner similar to Ptahhotep’s, providing a flexible range of norms allowing, for example, hate speech to be dealt with by criminalization, or in civil law, or by means of ethics rules and self-regulation, depending on the severity of the involved threats to humanity, to human beings, or to other core values. We reject an often-paralyzing comparative intercultural juxtaposition of individualism versus collectivism, instead suggesting an inclusivist and interculturally principled common ground for the regulation of communication.
