Authors: Kosmadakis George , Martinez Marie , Andre Sandrine , Da Costa Correia Enrique
Published: July 2021

BACKGROUND: Pressure injuries (PIs) are a significant problem for health care institutions. PURPOSE: A retrospective study of patient data was conducted at a semi-urban state hospital in France, aiming to evaluate the rate of PIs and variables that may influence PI prevalence and care at 2 different time points. METHODS: Patient demographic, clinical, PI and PI prevention, and care variables were retrieved from the charts of all patients on all wards (except pediatrics and obstetrics) on October 20, 2009, and on October 24, 2013—4 years apart. Qualitative data were compared between the 2 dates using a t-test for independent variables. The remaining variables were compared using Pearson’s chi-square method. P < .05 was considered significant. RESULTS: No significant differences were noted in PI rates (19% for 2009 and 16% for 2013) or the timing of their occurrence (51% occurred following admission in 2009, and 58.3% occurred after admission in 2013). Significant differences were found with regard to patient age (average, 73.97 and 76.22 years old in 2009 and 2013, respectively; P = .014) and rates of serious injuries (27% and 43% were stages 3 and 4 in 2009 and 2013, respectively; P = .010). Compared with 2009, in 2013, significantly more patients were placed on a specialty mattress and provided nutritional supplements and fewer were provided percutaneous endoscopic gastrostomy or nasogastric tubes. CONCLUSION: The rate of PIs was not different between these 2 time points despite improvements in the use of preventive and therapeutic measures, perhaps due to the increased age and frailty of the patient population in 2013 compared with 2009. Additional prospective research across multiple health care entities is warranted.

The relationship of global cities' foreign trade and urban growth: Investigation on the axis of the panel causes analysis
Authors: ÖZAYTÜRK İbrahim , ÖZAYTÜRK Gürçem
Published: July 2021

Foreign trade is considered a factor that contributes to the development of regional, national and international economies. In addition to make it easier for the economic wheels to turn, it also increases the level of welfare. Foreign trade, which facilitates integration with the world, has increased in size with globalization and has become the locomotive of growth. Global cities, which are the places where this transformation is most evident, have taken their share from this development. As a matter of fact, external effects on urban growth also show themselves through globalization. However, in these cities where globalization is experienced most intensely, there is a shift from foreign trade, which is considered the locomotive of growth after spatial transformation, to different dynamics. The aim of this study is to examine the relationship between foreign trade and urban growth in global cities. For this reason, the direction of the relationship between urban growth and foreign trade of global cities with 2005-2019 annual data for seven global cities whose data can be accessed was determined by Pairwise Granger panel causality test. As a result of the analysis, the effect of foreign trade of global cities on urban growth was not found, but it was determined that urban growth had an effect on foreign trade of global cities.

Published: July 2021

HOTAIR is a long noncoding RNA (lncRNA) which serves as an important factor regulating diverse processes linked with cancer development. Here, we used comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS) to explore the HOTAIR-protein interactome. We were able to identify 348 proteins interacting with HOTAIR, allowing us to establish a heavily interconnected HOTAIR-protein interaction network. We further developed a novel near-infrared fluorescent protein (iRFP)-trimolecular fluorescence complementation (TriFC) system to assess the interaction between HOTAIR and its interacting proteins. Then, we determined that HOTAIR specifically binds to YBX1, promotes YBX1 nuclear translocation, and stimulates the PI3K/Akt and ERK/RSK signaling pathways. We further demonstrated that HOTAIR exerts its effects on cell proliferation, at least in part, through the regulation of two YBX1 downstream targets phosphoenolpyruvate carboxykinase 2 (PCK2) and platelet derived growth factor receptor β. Our findings revealed a novel mechanism, whereby an lncRNA is able to regulate cell proliferation via altering intracellular protein localization. Moreover, the imaging tools developed herein have excellent potential for future in vivo imaging of lncRNA–protein interaction.
A low energy community? A comparative study of Eco-Villages around the world
Authors: Bakshi Nilesh , Vale PR , Vale PB
Published: July 2021

This paper investigates what is being done to produce sustainable community developments to minimize ecological footprint. Five international case studies were compared with the Govardhan Eco Village in Maharashtra, India. The study describes each case study and then looks at how various sustainable principles have been integrated into the community. Each case study was compared to an appropriate set of sustainability indicators to see which parameters were addressed. In order to establish the fundamental sustainable design focus of each case study, whether technology or human behaviour, the analysis looked at the types of parameters governing each project. Results showed the parameters incorporated in the case studies did not obviously change with time. Further scrutiny of the parameter matrix for all case studies suggested two distinctly different trends in the 'eastern' and 'western' examples. The Indian example appears to show true sustainable development, relying less on technology and more on human capital.
Beyond recovery: Measuring ventilation strategies and their impact on energy
Authors: Bakshi Nilesh , Donn Michael , Ganda S , Wallace J
Published: July 2021

Working with a medium scale, research-focused architectural practice this paper measures the efficacy of balanced pressure heat recovery ventilation systems (BPHR systems) in the existing housing stock as a strategy to mitigate thermal heat loss when incorporating ventilation strategies in New Zealand. Current research indicates that BPHR systems boast an efficiency upwards of 80%. The aim of this research is to determine at what point do BPHR systems meet current claims of efficiency. An examination of the existing New Zealand housing stock identifies that 66% of all dwellings do not meet thermal performance requirements. This has been attributed, in part, to the governance of legislation of minimum performance, which did not exist until 1978. This paper, first, identifies building simulation measures and assumptions to accurately simulate BPHR systems in controlled conditions, which is quality assured against the expected performance of a conventional code minimum residential building and a range of models that represent a spectrum of building leakage for pre-legislation buildings. This paper then examines passive ventilation strategies in each model to identify the energy balance of using BPHR systems and the potential for heating energy loss when implementing simpler ventilation strategies. This study identifies that the efficiency of BPHR systems significantly differ in the pre-legislation building simulations. In these models, the building leakage alone renders heat recovery negligible in comparison to simple passive design and occupant-controlled measures thatm achieve a similar result for the indoor air quality.

Board Size and Firm Performance: Case of Kuwait
Authors: Al-Saidi Mejbel
Published: July 2021

This study examined the relationship between board size and firm performance using a sample of 110 non-financial listed firms on the Kuwait Stock Exchange (KSE) from 2009 to 2017 (9 years). Empirical tests were conducted using OLS and 2SLS regressions as well as two performance measures to control the issues of endogeneity and causality; the study found that board size negatively affected firm performance. Thus, a small board size is better for non-financial Kuwaiti listed firms, which is consistent with agency theory and the majority of previous studies conducted in developed and developing countries. However, the causality issue does exist. The study makes a number of contributions to the corporate governance literature—namely, it provides a good understanding of the relationship board size and firm performance. In addition, examining such variables without considering the issues of endogeneity and causality would lead to misleading results. Finally, this study provides clear evidence for regulators in Kuwait to design an optimal board size to improve listed firms.
The role of family social support on work stress for frontline working mothers in Bangladesh
Authors: Uddin Mahi
Published: July 2021

Due to the increased entry of women into the workforce, there have been changes in socio-economic and familial changes in Bangladesh. Traditional family demands on women also increase along with this. Thus, working mothers experience more stress than men. In the context characterized by minimum formal support structures, working mothers need to resort to family resources to cope with stressful situations arising from work and family roles. Hence, this study aims to investigate the role of family support in alleviating work stress. Data were collected from 332 frontline working mothers (banks= 179, healthcare= 153) employed in banking and healthcare organizations located in Dhaka and Chittagong in Bangladesh. Grounding on the COR theory, the findings revealed that emotional, instrumental, and housework family support negatively influenced work stress of working mothers in banks, whereas instrumental and housework family support had negative influence work stress of mothers in the healthcare sector. The findings imply that family social support generates valuable resources for working mothers in the healthcare and banking professions in dealing with stressful work situations during pandemic situations. Family support is also a valuable resource for working women in a patriarchal society where gendered stereotypes shape working women's work stress. This study provides a clear understanding of how various family supports reduce the work stress of women. This study suggests organizations enable working mothers to cope with any unintended detrimental effects of using family support.

Published: July 2021

Myeloid sarcoma infiltration into the breast of patients with acute myeloid leukemia is rare. The present study reports the case of a 56-year-old woman diagnosed with AML and an incidental finding of a breast tumor. The nodule biopsy raised the suspicion of invasive lobular carcinoma and poorly differentiated angiosarcoma. Subsequent immunohistochemical study concluded the diagnosis of myeloid sarcoma. The varied image presentations, the lack of knowledge of clinical data and complementary propaedeutics, and the histopathological similarity with certain primary breast lesions make it difficult to discover secondary infiltration by myeloid sarcoma in this unusual site.

Abstract. Marriage that will bring peace and spirituality, must have the same religious beliefs, must not be of different religions, in accordance with the Word of Allah, Surat Al-Baqarah: 221 and encouraged by Law Number 1 of 1974 concerning Marriage, with this type of qualitative research. In the case of interfaith marriages, which are manifested in related books, journals, theses, articles, do not forget the Al-Qur'an and Sunnah in accordance with this theme. The purpose of this research is to look in depth about interfaith marriage according to Islamic law and according to the Marriage Law. What are the views of these two sources and the location of the similarities or similarities of Islamic law and the law on interfaith customary marriages. The result of this research is that in Islamic law it is not allowed because of a new breakthrough in faith. Therefore, inter-religious marriages, for various reasons such as better than allowing cohabitation. There is also the opinion that this may have been her match and is a human right. This reason cannot be accounted for, both in Islamic law and in state law, because in law, marriage will be said to be valid according to the law of each religion, it is said to be valid, because marriage will be accounted for before Allah SWT as a creator who has worked with all His perfection.

Abstrak. Perkawinan yang akan membawa ketenangan lahiriyah dan bathiniyah itu, harus sama keyakinan agamanya, tidak boleh berbeda agama, sesuai dengan Firman Allah Surat Al-Baqarah : 221 dan di dorong dengan Undang-undang Nomor 1 Tahun 1974 Tentang Perkawinan, dengan jenis penelitian kualititif yaitu menelusuri terhadap pelaku terjadinya perkawinan beda agama dan dihubungkan dengan buku-buku yang terkait, jurnal, skripsi, artikel tidak lupa Al-Qur’an dan sunnah yang sesuai dengan tema ini. Tujuan dari penelitian ini adalah ingin mengetahui secara mendalam tentang pernikahan beda adat beda agama menurut hukum Islam dan menurut Undang-Undang Perkawinan. Bagaimana pandangan dari dua sumber tersebut serta letak perbedaan atau persamaan dari hukum Islam dan Undang-undang mengenai perkawinan adat beda agama. Hasil dari penelitian ini bahwa dalam hukum Islam tidak diperbolehkan karena menyangkut perbedaan iman. Oleh sebab itu, perkawinan antar penganut agama, dengan berbagai macam alasannya seperti lebih baik dari pada membiarkan kumpul kebo. Ada juga beranggapan bahwa ini mungkin sudah jodohnya dan merupakan hak asasi manusia. Alasan tersebut tidak dapat dipertanggungjawabkan, baik secara hukum Islam maupun hukum negara, karena dalam undang-undang pun perkawinan akan dikatakan sah apabila menurut hukum masing-masing agama nya dikatakan sah, karena perkawinan akan dipertanggungjawabkan dihadapan Allah SWT sebagai pencipta yang telah mengatur kehidupan dengan segala kesempurnaan-Nya.

Optimization of reconstruction parameters in [18F]FDG PET brain images aiming scan time reduction
Authors: Pinto Samara Oliveira , Caribe Paulo R. R. V. , Narciso Lucas , Marques da Silva Ana Maria
Published: July 2021

Iterative image reconstruction methods are widely used in PET due to their better image quality when compared to analytical methods. However, inaccurate quantification occurs in low activity concentration regions, which leads to biased quantification of PET images. The diagnosis of some neurodegenerative diseases, such as Alzheimer’s disease, is based on identifying such low-uptake regions. Furthermore, PET imaging in these populations should be as short as possible to limit head movements and improve patient comfort. This work aims to identify optimized reconstruction parameters of [18F]FDG PET brain images aiming to reduce image acquisition time with minimal impact on quantification. For this, [18F]FDG PET images of a Hoffman 3-D brain phantom were acquired. Analytical and iterative reconstruction methods were compared utilizing image quality and quantitative accuracy metrics. OSEM reconstruction algorithm was optimized (4 iterations and 32 subsets). It resulted in remarkably similar images compared to the current clinical settings, with a 50% reduction in scan time (5 min with a post-reconstruction filter of 4 mm). Future clinical studies are needed to confirm the results presented here.
Detecção de Fraturas Ósseas em Fantomas por Espectroscopia de Impedância
Authors: Gueler Dalvi Giovanni , Bertemes Filho Pedro
Published: July 2021

A maioria das técnicas de diagnóstico por imagem para detecção de fraturas ósseas utiliza equipamentos que emitem radiação, que pode ser prejudicial à saúde humana, mesmo em pequenas doses. Sem dúvida, estudos são necessários e novas técnicas que busquem a redução dessas exposições ao raio-x. O objetivo deste artigo é desenvolver um fantoma biológico 3D e investigar a sensibilidade de detecção de ossos, inteiro e fraturado, por meio da espectroscopia de impedância elétrica. Além disso, são investigados os efeitos das diferentes posições dos eletrodos na sensibilidade da técnica de medição. As medições foram realizadas por um espectroscópio de impedância comercial da Zurich Instruments (modelo HF2IS) na faixa de frequência de 1 kHz a 1 MHz. Quatro eletrodos circulares (modelo MELCTEC) foram usados ​​para conectar o fantoma ao HF2IS. O HF2IS foi inicialmente calibrado medindo um resistor de 100 Ω e 1% de precisão. Vetores de calibração de magnitude e fase foram calculados e então usados ​​para ajustar os dados dos fantomas com e sem osso. Os resultados mostraram que os valores de módulo e fase para o simulador puro e com osso fraturado são bem próximos enquanto para o osso inteiro apresentam notável variação, principalmente em frequências acima de 100 kHz. Observou-se que a distância entre os eletrodos causa um pequeno efeito no módulo de impedância, enquanto as mudanças de fase são mais significativas em alta frequência. Também foi observado que a fase de impedância é mais sensível à geometria do eletrodo com e sem ossos fraturados. Esta pode ser uma ferramenta útil para detecção sem imagem de fraturas de ossos humanos como uma abordagem de baixo custo, não invasiva e não prejudicial à saúde humana.

Objective This study aims to investigate the prevalence and psychological impact of social isolation and loneliness in South Korea. Loneliness and social isolation have been regarded as a risk to both physical and mental health. However, most studies have focused on the elderly; hence, there are limited studies on the characteristics of socially isolated or lonely people considering age.Methods A sample of 1,700 participants was selected from three major cities in South Korea. In-person interviews were conducted to evaluate loneliness, social isolation and mental health status.Results Among the participants, the prevalence of social isolation and loneliness was 17.8% and 4.1%, respectively. Males decreased the odds of loneliness (AOR 0.49, 95% CI=0.28–0.87), while increasing the odds of social isolation (AOR 1.44, 95% CI=1.12–1.86) after adjusting for age and sex. Greater depressive and social phobic symptoms were associated with increased odds of loneliness and social isolation.Conclusion Social isolation and loneliness are prevalent among Koreans and associated with depression, social phobic symptoms, and suicidality. This study provides a foundation for further research to investigate nationwide prevalence and a more in-depth analysis of loneliness and social isolation.
The Professionalization of Cultural Managers in Spain
Authors: Mesa Laura del Valle , Ortíz Saúl L|zaro , Madariaga Celeste Jiménez de
Published: July 2021

The professionalization of cultural management in Spain emerged as a complex process in which the demand for professionals anticipated the existence of an academic discipline to support qualified knowledge, giving rise to strong epistemological debates. The main objective of this research paper is to study the development of the profession linked to the political, social, institutional and economic context, finding a recent research gap. The methodological triangulation of the various sources has revealed the importance of public and private systems in the definition of professional competencies, endowing them with a strong technical character that has been reflected in the theoretical development of cultural management. A lack of consensus between professionals, associations, entities and academies has been detected, showing the current fragmentation caused by the interest of certain sectors in maintaining the status quo that existed prior to the academic development of the profession. Scientific involvement in theoretical and educational development is necessary to guarantee adequate professional compliance in the practice of cultural management.
El México que no fue: The Tentative Retelling of Luis Donaldo Colosio’s Assassination
Authors: Marini Anna Marta
Published: July 2021

On the occasion of the 25th anniversary of his death in 2019, Netflix released two limited series focused on Mexican presidential candidate Luis Donaldo Colosio and his assassination. 1994 (directed by Diego Enrique Osorno) and Crime Diaries: The Candidate (Historia de un crimen: Colosio, directed by Hiromi Kamata and Natalia Beristáin) are, respectively, a documentary series and a drama, both delving into the political conjuncture surrounding both Colosio’s candidacy and the investigations subsequent to his assassination. Since his dramatic death, the image of Colosio has maintained its associations with heroism and his unrealized presidency has come to embody the “México que no fue,” a radically innovated Mexican state that never was and, possibly, will never be. Both series rely on the exploitation of original footage and underlying political takes on the events. This analysis will critically compare the two series from three main thematic perspectives: the Mexican political context at the time of the assassination; Colosio’s characterization and private life; and the procedural aspects of the investigations.
Women's Income-Generating Activities and Gender Roles in Rural Households in Mayo Danay Division, Northern Cameroon
Authors:   National Centre of Education, SILIKAM Julie Jasmine , ESSOUNGA Angeline Raymonde NGO
Published: July 2021

In sub-Saharan Africa, women participate in the rural labor market where they are present in subsistence agro-pastoral activities, which are more domestic work and, in other income-generating rural activities such as trading. Within the studies carried out on women’s status in communities, those on women's access to income-generating activities in certain contexts such as Ghanaian urban areas, have revealed that, income-generating activities contribute to a redistribution of gender roles in households. This paper by questioning the impacts of women's economic activities on gender relations within households in rural areas of Northern Cameroon, aims to analyse the realities faced by women involved in income-generating activities in a particular rural area to assess if the changes mentioned above happened in all communities. The data used for this work are empirical data from a qualitative survey of 48 women living in 8 villages in Mayo Danay, an administrative territory in Northern Cameroon. The results of this survey reveal that rural women involved in income-generating activities are both breadwinners and domestic workers. Contrary to what was observed in Ghana, the status of female breadwinners does not participate in the emancipation of women. Indeed, even with their means of production, women are still dependent on men and are still alone to bear the burden of the domestic work. Access of women to income-generating activities and their participation in household expenditures have surely reduced poverty in households but have not contributed to gender roles changes.
French artisan food co-operatives at the intersection between the artisan dimension and industrial logic – A two case study analysis
Authors: Adderley Simon , Gray Lee
Published: July 2021

This article provides two case studies of food manufacturing co-operatives in France. Both co-operatives were formed after large multi-national firms ceased manufacturing in a specific factory and the workers, rather than accepting redundancies, established an artisan production company based on “traditional” techniques and co-operative values. In order to do this it utilises the often overlooked literature of the artisan craft movement.  While this literature has been primarily developed around the emergence of artisanship in the third world it will be argued that such conceptualisations are also useful when exploring the development of artisanship amongst co-operative companies who are re-establishing their traditional ways of working, even in the “developed world”.   In doing so it builds on the work of Dickie and Frank (1996) who stated that “through crafts, tradition is maintained and/or invented, and marketed to consumers who find other meanings in the objects.” The theoretical construct posited by this article maintains that businesses with non-traditional economic models actually faced a complex and multi-faceted series of pulls in a number of different directions.  Furthermore that businesses re-establishing themselves as artisan manufacturers using locally sourced materials with democratic models of governance can be directly compared to artisan craft producers from the developing world. The article draws attention to the parallels between two important research areas which have not been linked before.  By doing so it has important implications for the mechanisms by which support is given to emerging co-operatives in the developed world and the a priori assumptions which underpin current policy.
Punitive operations and their victims: 1941—1944 (based on materials from Belarus and North West Russia)
Authors: Korsak Alesya , Krasnozhenova Elena
Published: July 2021

The article deals with the Nazi occupation policy on the border territory of Belarus and the North-West of Russia during the Great Patriotic War. The study of this problem is based on the materials of the Extraordinary State Commission and acts drawn up by the partisan command or underground authorities, as well as on the recollections of eyewitnesses of a later time. Mass graves of victims of Nazism found in Belarus and North-West Russia serve as reminders of the terrible days of the occupation.
Decent work and Safe Work: A Case study of IT Industry
Authors: NAUSHEEN NIZAMI
Published: July 2021

Workers are the backbone of an industry as well as an economy. Accelerating growth requires ensuring, understanding and managing life of workers when they are at work. This paper analyses the meaning and importance of safe work in Information Technology industry where work is rendered in apparently safe environment. IT industry has been chosen as it apparently offers highly remunerative packages but compromises on some of the essentials of decent work. One of the dimensions of decent work is safe work. In this paper, work safety has been measured on the basis of rudimentary statistical tools and non-parametric tests. Primary data collected from 272 IT employees by using snowball sampling technique and a well-designed questionnaire have been used for developing Safe work Index (SWI) on the lines of decent work agenda of the International Labour Office. Findings reveal deficit of safe work in IT companies and deteriorating health status of IT employees which has implications for the social health of the nation. The nature of work in IT industry which requires longer hours at work, constant sitting posture and working on computer screens has started playing havoc among the employees of younger age group and calls for attention for provision of decent ergonomic furniture and timely breaks from a sitting posture. The paper concludes with suggestive measures for the same.
How does business power operate? A framework for its working mechanisms
Authors: Babic Milan , Huijzer Jouke , Valeeva Diliara , Garcia-Bernardo Javier
Published: July 2021

The global financial crisis of 2008, its following bank bailouts and associated corporate impunity sparked a renewed interest in the concept of the structural power of business and the question of “who rules?” in capitalist societies. This new wave of scholarship mitigated some of the problems of the original, theory-driven discussions from the 1970s and 80s. But despite significant advancements in the empirical identification of business power, we lack a unified framework for studying its working mechanisms. So-called “hybrid approaches”, integrating instrumental and structural power into their analyses, display high potential for such a unified and easily applicable framework. We build on this hybrid tradition and propose a novel model that integrates instrumental and structural power analysis into a basic framework. With this, we go beyond the often rigid division between instrumental and structural power forms and integrate the role of perceptions as key for understanding the dynamics of business power over time. We illustrate this parsimonious framework by an analysis of the plans of the Dutch government to abolish a dividend tax in 2018 that would have benefited a number of large multinationals but collapsed before implementation.
How to Distinguish Motivated Reasoning from Bayesian Updating
Authors: Little Andrew T.
Published: July 2021

Can we use the way that people respond to information as evidence that partisan bias or directional motives influence political beliefs? It depends. Using one natural formalization of motivated reasoning as wanting to believe certain things are true (``once-motivated reasoning''), this is not possible. Any subject influenced by this kind of motivated reasoning has a ``Fully Bayesian Equivalent'' with a different prior, who has identical posterior beliefs upon observing any signal. This result clarifies what we can and cannot learn from several prominent research designs, and identifies a set of results inconsistent with both Bayesian updating and once-motivated reasoning. An extended version of the model where subjects also may completely reject signals which lead to less pleasant beliefs (``twice-motivated reasoning'') explains these anomalies. These formalizations clarify which empirical tests can detect different kinds of motivated beliefs, and can easily be incorporated into decision- and game-theoretic models.
STATUS GIZI BALITA
Authors: Khaeria Najwa
Published: July 2021

Status gizi adalah keadaan gizi seseorang yang dapat dilihat untuk mengetahui apakah seseorang tersebut itu normal atau bermasalah (gizi salah). Gizi salah adalah gangguan kesehatan yang disebabkan oleh kekurangan atau kelebihan dan atau keseimbangan zat-zat gizi yang diperlukan untuk pertumbuhan, kecerdasan dan aktivitas atau produktivitas (Siswanto, 2001). Status gizi juga dapat merupakan hasil akhir dari keseimbangan antara makanan yang dimasukkan ke dalam tubuh (nutrient input) dengan kebutuhan tubuh (nutrient output) akan zat gizi tersebut (Supariasa, dkk., 2002). Status gizi balita merupakan salah satu indikator yang dapat digunakan untuk menunjukan kualitas hidup suatu masyarakat dan juga memberikan intervensi sehingga akibat lebih buruk dapat dicegah dan perencanaan lebih baik dapat dilakukan untuk mencegah anak-anak lain dari penderitaan yang sama (Soekirman, 2000).
