The article aims to identify main research challenges in studying coworking spaces (CSs) within the field of economic geography. It combines the perspective of proximity economics with the growing body of papers about spatial aspects of the operations of CSs and their role in stimulating collaboration. Based on a review of literature, the author identified the characteristic features of CSs and the corresponding proximity dimensions. He further assessed the significance of various dimensions of proximity in CSs. The article reveals how various proximities differ between CSs. It also distinguished the research strands referring to the spatialities of CSs. Next, it discusses the conceptualisation and operationalisation of proximity. Then, it applied it in the micro-scalar context of coworking spaces. The paper sheds a new light on ‘real CSs’ as physical spaces of strong institutional, cognitive and social proximities. It has been argued that even if organisational proximity in CSs is taken for granted, there is a heterogeneity amongst their users.

Attitudes And Behavior

This article explores a case of human–wildlife cohabitation in the Rodopi mountains of Bulgaria, wherein people and brown bears ( Ursus arctos) have adapted to living together in relative harmony. While this is due to a variety of factors, chief among these is the way both people and bears appear to pursue knowledge of one another and act on this knowledge so as to actively minimize potential for conflict. We draw on this case to contribute to growing discussion concerning how nonhumans should be understood and included within conservation policymaking. While conservation has conventionally been understood as something humans do on behalf of other species, a growing body of “more-than-human” research challenges this perspective as “anthropocentric” in arguing that nonhumans should be considered “co-constitutive actors” of the spaces they occupy. Based on this understanding, some go so far as to assert that a “multispecies ethics” demands that nonhumans be actively included in decision-making concerning such spaces’ governance. While our study indeed demonstrates that both humans and bears seem to mold their behavior in relation to their sensing of the other’s behavior, it also demonstrates that knowledge of bears’ behavior is ultimately always interpreted by humans in conservation management. Moreover, different groups of stakeholders hold different knowledge of bears that influence their attitudes and behavior towards the animals. The study thus raises important questions concerning how to incorporate bears (and other nonhumans) within conservation decision-making, and whose knowledge should be privileged in the process.

Background. The aetiology of trigger digits has been debated since Notta first described them in 1850. Aetiology has been segregated for adult and paediatric presentations. While an adult trigger digit is most likely an acquired inflammatory process, the same is not true for cases in children: no inflammatory reaction is seen on microscopic evaluation. We wish to add strength to a genotypical aetiology for paediatric cases. Methods. We present two cases of monozygotic twins with trigger digits managed in our institution. A comprehensive review of literature was conducted for cases of trigger digit in monozygotic twins to support our theory. Results. Our two sets of twins enjoyed a full recovery from surgery at one-month follow-up. A total of seven other cases of monozygotic twins were found in literature. Conclusion. Our cases add to the growing body of evidence supporting a genotypical aetiology for paediatric trigger digit.

Small Round Cell Tumour

Desmoplastic small round cell tumor (DSRCT) is a rare pathologic entity that most frequently affects the peritoneal cavity and presents in pediatric and adolescent boys. It often presents at an advanced stage and has a generally poor prognosis. Sometimes it may involve liver at diagnosis. We present an unusual case of DSRCT who was present with mass in lower abdomen, pain, hepatomegaly and mild ascites. This tumor is characterized by nests of small undifferentiated cells that show immunohistochemical evidence of epithelial, mesenchymal and neural differentiation. In our patient histologicaly tumor had the characteristic features of DSRCT and were composed of small round cells with hyperchromatic nuclei and scanty cytoplasm. With various difficulties in diagnosis we ultimately reached at diagnosis by open biopsy and immunohistochemistry. Now patient is on multidrug chemotherapy (modified p6 protocol). Diagnosis and management of a rare tumor needs high level of suspicion and in time intervention.DOI: http://dx.doi.org/10.3329/jpsb.v2i2.19552

Abstract Background The Italian National Institute of Health (Istituto Superiore di Sanità, ISS) considers health inequalities (HI) an important area of activity. As the scientific and technical body of the Ministry of Health and the National Health Service, ISS may play a key role to reduce HI. In order to enable ISS in addressing the new and crucial HI challenge, a Research Positioning Exercise was designed and implemented. Methods The Exercise included: (i) workshop to strengthen the institutional interest in the field of HI; (ii) review and analysis of ISS publications (years 2000–2017) to identify HI research topics; (iii) survey among ISS researchers regarding main research challenges to address HI in the coming years; and (iv) analysis of input on research challenges from HI international experts. Results The results of this Exercise suggest that the following points should be included in the future ISS agenda planning: (i) themes which ISS should continue working on (e.g. migrants/vulnerable groups); (ii) themes to be improved: (a) relationship between social determinants and mechanism of HI generation and (b) relationship between risk factors exposure and social determinants; and (iii) new themes to be addressed: (a) mechanisms underlying the resilience observed in Italy; (b) new socioeconomic indicators for HI monitoring; and (c) evidence-based policies aimed at reducing HI. Conclusion Findings of this Exercise show that ISS researchers identified relevant areas, addressing inequalities in addressing the health. Because of ISS structural peculiarity that includes multidisciplinary expertise, the ISS could provide a significant contribution to HI research challenges and knowledge gaps.

AbstractThis paper treats the concept of ‘field-configuring events’ (FCE) and relates it to economic geographical research. The FCE approach attempts to draw attention to the role of events in fields of economic and social action and suggests that events can be important to introducing, structuring, maintaining and configuring new products, industrial standards, cultural artefacts and knowledge categories. The FCE approach has primarily been used to study the actors and networks associated with events such as trade shows, professional gatherings, technology contests, cultural tournaments, industrial exhibitions and business ceremonies: events where actors assemble to reveal novel products, develop industry designs, initiate cultural trends, create social networks, and allocate meaning to previously unfamiliar circumstances. In this introductory paper, we identify the main research trajectories in FCE and link these to economic geography by identifying some common lines of thinking apparent in economic geography, management and organisational studies. The paper moves on to investigate the nature of the “field”, “configuration” and “events” from a geographic perspective, and to emphasize the role that space and power play as a structuring mechanisms in all three. We conclude that the FCE approach can function as a useful tool for geographical analysis of the increasing fluid and episodic contours of the contemporary space economy.

Precoding Vector

The open radio access network (O-RAN) concept is changing the landscape of mobile networks (5G deployment and 6G research). O-RAN Alliance’s suggestions that O-RAN can offer openness and intelligence to the traditional RAN vendors will enable the capability for multi-vendors to re-shape the RAN structure and optimize the network. This paper positions the main research challenges of the O-RAN approach in regards= to the implementation of beamforming. We investigate the O-RAN architecture and the configurations of the interfaces between O-RAN units and present the split options between the radio and distributing units in terms of O-RAN specification and 3GPP standards. From this point, we discuss the beamforming methods in O-RAN, addressing challenges and potential solutions, and suggest the introduction of the zero-forcing equalizer as a precoding vector in the channel-information-based beamforming method. This may be one of the solutions for achieving flexibility in a high-traffic communication environment while reducing the radio unit interferences caused by implanting the precoding in the open radio unit.

Financial Geography

 As an important branch of economic geography, financial geography has important significance for maintaining the stable operation of the financial industry and thus promoting social and economic development. Based on the perspective of geography, we first combed the development history and main research fields of international financial geography. According to the differences of mainstream research methods in a specific period, the development process can be divided into three stages: germination, political economics and economic geography. With the help of literature measurement analysis, the international financial geography research is divided into the classic research field focusing on the financial center, the spatial evolution of financial subjects, the financial network and regional interaction, and the emerging research fields with different scales of financialization. Then it summarizes the progress of China’s financial geography research. Although China’s financial geography started late, there is still a gap between the breadth and depth of research compared to foreign countries, but its institutional background is different from the Western institutional background. It provides a diversified explanation for its own specific financial landscape. Finally, combined with the development status of financial geography at home and abroad, the research prospects of this discipline are prospected.

Warfarin Dosing

Background: Chronic Kidney Disease (CKD) is a prevalent worldwide health problem. Patients with CKD are more prone to developing cardiovascular complications such as atrial fibrillation and stroke. This warrants the use of oral anticoagulants, such as warfarin, in this population. While the efficacy and safety of warfarin in this setting remain controversial, a growing body of evidence emphasizes that warfarin use in CKD can be problematic. This review discusses 1) warfarin use, dosing and outcomes in CKD patients; and 2) possible pharmacokinetic mechanisms for altered warfarin dosing and response in CKD. Methods: Structured search and review of literature articles evaluating warfarin dosing and outcomes in CKD. Data and information about warfarin metabolism, transport, and pharmacokinetics in CKD were also analyzed and summarized. Results: The literature data suggest that changes in warfarin pharmacokinetics such as protein binding, nonrenal clearance, the disposition of warfarin metabolites may partially contribute to altered warfarin dosing and response in CKD. Conclusion: Although the evidence to support warfarin use in advanced CKD is still unclear, this synthesis of previous findings may help in improving optimized warfarin therapy in CKD settings.

Objectives: Aggressive angiomyxoma is known as a mesenchymal tumor of premenopausal women and it is extremely rare in men. Methods: Herein, we report a 66-year-old male with a firm scrotal mass that had gradually enlarged over 20 years. Results: Radiological studies revealed 10 x 15 cm mass lesion confined to right scrotum with neither local invasion nor distant metastasis. Inguinal orchiectomy was performed and histopathology showed characteristic features of an aggressive angiomyxoma occupying paratesticular region, which was a challenging diagnosis due to its unexpected occurrence in the male gender. Conclusion: Aggressive angiomyxoma is mostly considered as a benign tumor in females despite its propensity for local recurrence. Whether it may show a divergent biological behavior in men is unknown as the reported cases are too few.
