Authors: Rozaq Moch , E. D. R Wirawan
Published: March 2021

This study examined the impact of layout changes or re-layout on the turnover of the tenants at the Culinary Center Convention Hall (SKCH) Surabaya. The aspects studied concerned spatial purpose and layout functions. Spatial purpose included area expansion, ease of access and lighting, and equalization considerations for tenants. Layout functions included the variable of SKCH’s location. The four variables support layout changes, thus increasing the turnover of the tenants in SKCH. A descriptive qualitative method was used. The study included all 25 tenants who were in SKCH before and after the re-layout. Each aspect indirectly brought a positive influence on the increase in turnover of the majority of tenants at SKCH, with the purpose aspect of spatial layout increasing the turnover of 64% of tenants and the aspect of layout function increasing the turnover of 92% of tenants.

The Impact of Owner Gender in Family Businesses in Indonesia Liliana Dewi, Kazia Laturette, and I Gusti Bagus Yos
Authors: Dewi Liliana , Laturette Kazia , Wiryakusuma I Gusti Bagus Yosia
Published: March 2021

There are differences in the way people perceive the role of women and men in business. The purpose of this study was to analyze the influence of male or female leaders on two business families in Indonesia. The success of the family company cannot be separated from the role of the first generation in trusting future generations to continue their family business. A qualitative approach was used, where the data were collected through interviews with two family companies with different generations of successors. One family company has a female successor generation and another family company has a male successor. The findings showed that the first generation trusted from an early age and involved the second generation in the family business, whether their children were girls or boys. In fact, all succeeded in taking over the baton of leadership. An interesting finding is that even though the next generation is female and handles welding, which is more commonly done by men, thanks to the trust given by their parents, this next generation would be more masculine in order to gain legitimacy from employees who have worked for a long time in the company. This is as good as the next generation of men in other family companies.

The Value of Financial Education During Multiple Life Stages
Authors: Gibson Philip , Sam Janine K. , Cheng Yuanshan
Published: March 2021

This study examines the timing of financial education and its impact on short-term and long-term financial behavior. We also explore the power of financial education on financial knowledge and examine the link between financial knowledge and positive financial behavior. Exposure to financial education during multiple life stages leads to a better financial outcome. Financial education taught via multiple channels, including high school, college, the workplace, and at home, is the most optimal in the long run. For those who did not attend college, being exposed to financial education in high school is significantly associated with positive financial behavior. We cite implications for all financial education advocates. Policymakers in the financial capability arena can stay abreast of the channels of financial education that produce the most fruitful economic and societal gains.

Valuing plant genetic resources in genebanks: Past, present and future
Authors:   Michigan State University, USA, Smale Melinda , Jamora Nelissa ,   Global Crop Diversity Trust, Germany, Guarino Luigi ,   Global Crop Diversity Trust, Germany
Published: March 2021

Though the intrinsic value to society of plant genetic resources conserved in genebanks may be recognized, assigning a cardinal value to them remains elusive. This chapter summarises the main messages from applied economics literature on genebank values that began in the late 1990s, a recent set of studies undertaken by the CGIAR Genebank Platform and Crop Diversity Trust, and assessments of national genebanks. Three points are salient: the value of information; the demand for a diversity of approaches to document the diversity of ways that genebanks benefit society; and the need to establish priorities for collecting and conservation based on cost-effectiveness. Cost-effectiveness will require a) carefully targeted investments in characterization, evaluation, and genotyping, along with management of the resulting data, and its use to develop packages of breeder- and researcher-oriented materials, and b) investment in supportive research and various organizational optimization procedures, including automation.

The Brassica genus contains many agriculturally important oilseed and vegetable crops. Brassica germplasm, including natural accessions and breeding populations, are maintained globally for sustainable management and enhancement of Brassica crop production which is critical to meet the demands of population growth and challenges of environmental stresses due to global climate change. DNA based markers, such as SNPs, are commonly used to screen large numbers of Brassica germplasm for conservation, genetic mapping and association studies. This chapter focuses on the application of SNP genotyping technologies for conservation of Brassica germplasm, uncovering the genetic basis of various biotic and abiotic stresses and screening for yield related traits and oil quality through marker-trait association studies.

Ciotki i inne pokrewne nazwy w językowym świecie gejów
Authors: Narloch Robert
Published: March 2021

The article describes word formation with the lexeme aunty and auntie. At the same time, it is also a collection of various word-formation forms that describe the linguistic image of gays and show how complex the question of their identity is. The text also explains the difference between defining the words aunty and auntie, with particular emphasis on the intention of the sender and the group of recipients from which both the sender and the recipient of the statements cited in the article come from. The author of the article also draws attention to the influence of camp on shaping gay identity and on the way gays talk (communicate to the world) about themselves. The different subtypes of non-heteronormative males were particularly strongly emphasised in the article by means of appropriate quotes from the magazine “MEN!”. Listing word-formation formations in the article allowed the author to show not only one of the elements of the linguistic image of the world of gays, but also to indicate specific types of fags, how oft en homosexual men play with their sexuality. What is more, the combinations with the lexeme aunt are to serve primarily to describe the linguistic image of the gay world, through which they refer to stereotypes that are very often attributed to people from the gay community.
Manipulated memory. Right-winged media narratives about homosexual prisoners of concentration camps
Authors: Kumala Aleksandra
Published: March 2021

The article offers a critical interpretation of the chosen online activity of right-wing journalists and Internet users that seem to sympathize with this political option. Selected Tweets and articles are understood as exemplifications of either intentional, unconscious or ignorance-caused manipulations of memory, its object being homosexual prisoners of the Nazi concentration camps. Placing selected Tweets in a broader social, political, as well as historical context, the author shows the discursive exclusion of this group of the Nazi’s “forgotten victims” in the Polish media sphere, (re)producing the negative only image of homosexual prisoners and the tendency to falsely identify camp homosexual violence with camp homosexuality as such.
My performance is my world. Queer and normativity in the practices of New York’s ballroom culture
Authors: Kiełpiński Łukasz
Published: March 2021

The central concept of the article is performance as a form of expression specific to non-normative people. In confrontation with the oppressive discourse of dominant groups, the body of an excluded individual and its metamorphoses in themselves appear to be an alternative way of non-alienated expression. This phenomenon is discussed via the example of the practices of New York’s ballroom culture — primarily via the example of the film Paris is Burning from 1990, directed by Jennie Livingston. In the ballroom community, black and non-heteronormative Americans found a safe space for experiments with their identity, thanks to which they could experience a form of capitalistic success through an ephemeral performance. However, these practices, despite their apparent subversiveness and emancipatory potential, did not have the ambition to change the status quo. They only allowed experiencing the feeling of social advancement within the existing system. The story that ballroom culture members in the 1980s told about themselves through their own performances was part of a unique, non-verbal discourse of excluded groups, which developed a specific communication code based on the human body, its ways of moving and its aesthetic metamorphoses.
A articulação do reducionismo tecnicista à sofisticação tecnológica no discurso das políticas educacionais
Authors: Silva Andréa Villela Mafra da
Published: March 2021

A tese investiga as políticas educacionais no Brasil, implementadas na década de 1970 até 2015, analisando a inscrição das tecnologias na educação e focalizando os pressupostos e as implicações das formulações das políticas educacionais que as sustentam. A periodização assinala o predomínio da pedagogia tecnicista e a retomada deste movimento, de forma mais intensificada, nos anos reformistas neoliberais da década de 1990, objetivado no neotecnicismo, enquanto uma forma de organização das escolas, por parte de um Estado que busca maximizar os resultados dos recursos aplicados na educação. O estudo aponta para uma estruturação teórica em dois eixos centrais: (1) o reducionismo tecnicista – em que a formação de professores parte da dimensão acadêmica para a dimensão experimental/instrumental/pragmática e coloca a ênfase nas competências e habilidades dos professores e alunos para atingirem as metas e os resultados pré-estabelecidos; (2) a sofisticação tecnológica – a configuração do neotecnicismo centrado nos modos de incorporação educacional das TIC.

Published: March 2021

Introduction: Exposure to the clinical learning environment is indispensable for the nursing students as it provides experiences which are basic and significant to the development of professional skills as well as bridge the theory-practice gap. Despite the importance of clinical learning, nursing students’ attitudes in the clinical environment has been a concern.Purpose: This paper reviewed the attitude of nursing students towards work in the clinical learning environment.Method: Electronic searches using scholarly databases were employed and only significant articles that met the review objective were utilized.Findings: This review revealed that there is a high rate of unauthorized student nurses’ absenteeism as majority are absent from clinical work without permission. There is also an appalling display of lateness behavior as students arrive at work after the scheduled time. Interestingly, most students are willing to carry out procedures while some are nonchalant due to the stressful and anxiety provoking tasks. Student nurses felt that there is an unspoken comparison, discrimination and disrespect displayed by their seniors and medical colleagues towards them.Conclusion: There is overwhelming evidence from literature supporting the negative attitudes of nursing students in the clinical environment. It was therefore recommended that students should be psychologically prepared in their schools before exposure to the clinical environment. There should be an effort to build students’ self-esteem and professional self-concept by the relevant authorities. Finally, to bridge the rift between inter-professionals, there is need for more social interaction opportunities where everyone will value what each member contributes to the team.

Authors: Nalule Yolisa , Buxton Helen , Macintyre Alison , Ir Por , Pors Ponnary , Samol Channa , Leang Supheap , Dreibelbis Robert
Published: March 2021

Background: Globally, infections are the third leading cause of neonatal mortality. Predominant risk factors for facility-born newborns are poor hygiene practices that span both the facility and home environments. Current improvement interventions focus on only one environment and tar-get limited caregivers, primarily birth attendants and mothers. To inform the design of a hand hygiene behaviour change intervention in rural Cambodia, a formative mixed-methods research study was conducted to investigate the context specific behaviours and determinants of hand-washing among healthcare workers, maternal and non-maternal caregivers along the early new-born care continuum. Methods: Direct observations of hygiene practices of all individuals providing care to 46 newborns across eight facilities and associated communities were completed and hand hygiene compliance assessed in analysis. Semi structured interactive interviews were subsequently conducted with 35 midwives and household members to explore the corresponding cognitive, emotional, and environmental factors influencing the observed key hand hygiene behaviours. Results: Hand hygiene opportunities during newborn care were frequent in both set-tings (n = 1319) and predominantly performed by mothers, fathers and non-parental caregivers. Compliance to hand hygiene protocol across all caregivers, including midwives, was inadequate (0%). Practices were influenced by the lack of accessible physical infrastructure, time, increased workload, low infection risk perception, nurture-related motives, norms and inadequate knowledge. Conclusion: Our findings indicate that an effective intervention in this context should be multi-modal to address the different key behaviour determinants and target a wide range of caregivers.

Exercise can ameliorate cardiovascular dysfunctions in diabetes condition, but its precise molecular mechanisms have not been entirely understood. The aim of the present study was to determine the impact of endurance training on expression of angiogenesis-related genes in cardiac tissue of diabetic rats. Thirty adults male Wistar rats were randomly divided into three groups (N=10) including diabetic training (DT), sedentary diabetes (SD), and sedentary healthy (SH) in which diabetes was induced by a single dose of streptozotocin (30 mg/kg). Endurance training (ET) with moderate-intensity was performed on a motorized treadmill for six weeks. Training duration and treadmill speed were increased during five weeks, but they were kept constant at the final week and slope was zero at all stages. Real-time polymerase chain reaction (RT- PCR) analysis was used to measure the expression of myocyte enhancer factor-2C (MEF2C), histone deacetylase-4 (HDAC4) and Calmodulin-dependent protein kinase II (CaMKII) in cardiac tissues of the rats. Our results demonstrated that six weeks of ET increased gene expression of MEF2C significantly (P<0.05), and caused a significant reduction in HDAC4 and CaMKII gene expression in the DT rats compared to the SD rats (P<0.05). We concluded that moderate-intensity ET could play a critical role in ameliorating cardiovascular dysfunction in a diabetes condition by regulating the expression of some angiogenesis-related genes in cardiac tissues.
Modeling Pulsed High-Power Spikes to Drive Piezoelectric Broadband Transducers Improving SNR in Ultrasonic Imaging & NDE
Authors: Ramos Antonio , Ruiz Abelardo , Riera Enrique
Published: March 2021

Ultrasonic imaging & NDE applications can greatly improve their signal-to-noise ratios (SNR) by driving each transducer (composing piezoelectric arrays) with a spike giving pulsed power of k-Watts, repetitively at a PRF = 5000 spikes/s, by using a HV capacitive-discharge generator. However very-high levels, of pulsed intensities (3-10 A) and voltages (300-700 V) must be considered for a rigorous spike modeling. Even though the consumed "average" power will be small, the intensity through each transducer achieves several amperes, so the pulsed powers delivered by each HV generator can attain levels higher than in CW high-power ultrasonic applications: e.g., up to 5 kW / spike. This is concluded here from a transient modeling of the loaded generator. Then, unforeseen phenomena rise: intense brief pulses of driving power & emitted force in transducers, and non-linearities in driver semiconductors, because their characteristic curves only include linear ranges. But fortunately, piezoelectric devices working in this intense regime do not show serious heating problems, because the average power remains being moderate. Intensity, power and voltage, driving a broadband transducer from a HV capacitive pulser, are calculated to drastically improve (in ≅ 40 dB) the ultrasonic net dynamic range available, with emitted forces ≅ 250 Newtons pp and E/R received pulses of 70 V pp.

Published: March 2021

In the last years, more and more studies highlight the advantages of complementing traditional master classes with additional activities that improve students´ learning experience. This combination of teaching techniques is specially advised in the field of structural engineering, where intuition of the structural response it is of vital importance to understand the studied concepts. This paper deals with the introduction of a new (and more encouraging) educational tool to introduce intuitively students in the dynamic response of structures excited with an educational shaking table. Most of the educational structural health monitoring systems use sensors to determine the dynamic response of the structure. The proposed tool is based on a radically different approach, as it is based on low-cost image-recognition techniques. In fact, it only requires the use an amateur camera, a black background and a computer. In this study, the effects of both the camera location and the image quality are also evaluated. Finally, to validate the applicability of the proposed methodology, the dynamic response of small-scale buildings with different typologies is analyzed. In addition, a series of surveys were conducted in order to evaluate the activity based on student´s satisfaction and the actual acquisition and strengthening of knowledge.
Analysis of Valorization Process of Aluminum Breakage Scraps to Obtain Green Hydrogen
Authors: Salueña Berna Xavier , Marín-Genescà Marc , Daga-Monmany Josep Maria , Mujal-Rosas Ramon
Published: March 2021

In this article, it is proposed to use aluminum breakage scraps to obtain Green Hydrogen through the aluminum-water reaction with caustic soda as a catalyst. From this exothermic reaction, both hydrogen and the heat generated can be used. Due to the low price of aluminum chips, this allows us to produce Green hydrogen below the current price that is obtained using renewable energy sources and electrolyzers. On the other hand, we have developed a process that is sustainable since it is obtained as alumina and caustic soda waste that can be reused. This alumina obtained, once filtered, has high purity which allows us to produce high-quality primary aluminum without the need to use bauxite and reducing the production of red sludge. A comparative study-analysis has been carried out of two of the types of forms in which the most common aluminum is presented in the industry to analyze which one performs better by studying key factors such as the hydrogen produced, and the waste generated during the process. Finally, the mathematical model has been defined to be able to control the flow based on different key parameters such as temperature, molarity, and geometry. Undoubtedly, the study that we present represents a milestone for the recovery of metallic aluminum waste and may be of great interest to industries that use aluminum in their processes, such as recuperators, but also the vehicle or aerospace industry.
Mathematical Proof on the Existential Necessity of the World
Authors: Lee Young Hyeon
Published: March 2021

The "best of all possible worlds" theory (hereinafter the "possible world theory") was presented by Leibniz many centuries ago, and provided an opportunity for metaphysics to understand the ontological meaning of the world in an in-depth way. Furthermore, the theory has multiple impacts on the multiverse theory of modern physics. However, considering the ontological questions of the world solely on linguistics logic leads to basing the possible world theory or the multiverse theory on relatively uncertain inferential reasons. In this study, symbolic logic was used to consider the possible world theory on a more solid foundation. The entire world was made into oneness, and tracking the existential process at the beginning of the world, realized the existential necessity of the world, even though the initial causal point of the world was assumed to be completely void (null set). The existential system in this study, was generalized without specific elements, apart from existence and non-existence. It was discovered that existential possibility and existential necessity are logically equivalent.

With the results we are able to outline experiments with AEC2 repair of bleomycin damaged alveolar cells. If AEC2 repair capability is diminished by spike RNA then perhaps this result provides a first step on a route to treat immortal lung cancer cells.
Playable Personas: Using Games and Play to Expand the Repertoire of Learner Personas

This article explores how playing and co-creating games in higher education contexts contributes to expanding learner personas and facilitating a multimodal learning experience. Working from the interdisciplinary perspectives of media/games studies, pedagogy, and linguistic anthropology, we conceptualize in-class learning as the making and playing of games, reporting on game experiments and playful practices targeted at learning key theoretical concepts in our disciplines. Game-based modifications to established educational practices involved: replacing lectures with Educational Live Action Role Play (Bowman 2014) sessions, using acting/performance games (Flanagan 2009) to critically reflect on ideas of community and collective identity, and introducing Twine (Werning 2017; Wilson & Saklofske 2019) to defamiliarize the expected structures and media modalities of academia. Based on evidence from participant reflections and classroom ethnographies, we argue that games can serve as a resource for extending the expressive spectrum of learner personas, for enabling embodied, participatory learning of theory, and for empowering students and educators to reflect on our internalized rules of the game of education.
Hype Source: G Fuel’s Contemporary Gamer Persona and its Navigation of Prestige and Diversity
Authors: Tomkinson Sian , Elliott Jordana
Published: March 2021

G Fuel, an energy drink marketed towards gamers, performs a ‘contemporary’ gamer persona to interact with its audience, drawing upon an array of gaming influencers to appeal to fans of these figures. Specifically, this contemporary gamer persona builds upon the ‘geeky’ male gamer identity that has been constructed by marketers and adopted by players, utilising elements of esport such as skilfulness and focus. However, this persona also reimagines the gamer identity in alternative ways, such as gaming as an athletic activity – one that requires much mental and physical energy—and as an activity that connects players to others, and is exciting and glamourous, evocative of the lifestyles of gaming influencers. Thus, the contemporary gamer persona signals that there has been a shift in the popular discourses surrounding the ‘gamer’ identity in specific gaming micro-publics. The energy drink company G-Fuel is aware of this shift and strengthens this persona by forming partnerships with gamer microcelebrities and influencers. In this article, we find that in G Fuel’s construction and maintenance of the contemporary gamer persona, they seek to appeal to the wider gaming audience, but must constantly negotiate a balance between popular but controversial influencers and a commitment to diversity.

Background: The human gut microbiota exhibits marked variation around the world, which has been attributed to dietary intake and other environmental factors. However, the degree to which ethnicity-associated differences in gut microbial community structure and function are maintained following immigration or in the context of metabolic disease is poorly understood.Results: We conducted a multi-omic study of 46 lean and obese East Asian and White participants living in the San Francisco Bay Area. 16S rRNA gene sequencing revealed significant differences between ethnic groups in bacterial richness and community structure. White individuals were enriched for the mucin-degrading Akkermansia muciniphila. East Asian participants had increased levels of multiple bacterial phyla, fermentative pathways detected by metagenomics, and the short-chain fatty acid end products acetate, propionate, and isobutyrate. Differences in the gut microbiota between the East Asian and White groups could not be explained by reported dietary intake, were more pronounced in lean individuals, and were associated with current geographical location. Microbiome transplantations into germ-free mice confirmed that the differences in the gut microbiota of the East Asian and White individuals we analyzed are independent of diet and that they differentially impact host body weight and adiposity in genetically identical mouse recipients.Conclusions: The reported findings emphasize the utility of studying diverse ethnic groups within a defined geographical location and provide a starting point for dissecting the mechanisms contributing to the complex interactions between the gut microbiome and ethnicity-associated lifestyle, demographic, metabolic, and genetic factors.
Coronin 1A facilitates calcium mobilization and promotes astrocyte reactivity in HIV-1 Neuropathogenesis

BackgroundIn most neurodegenerative disorders, including neuroAIDS, reactive astrocytes are detrimental to the neuronal population. Calcium and its downstream regulators play a central role in mediating astrocyte reactivity. Coronin 1A, an actin binding protein, majorly reported in hematopoietic cells, regulates cell activity in a calcium-dependent manner, but its role in astrocyte physiology and reactivity is largely unknown. We explored the roles of Coronin 1A in astrocyte physiology and its involvement in facilitating astrocyte reactivity. MethodsCoronin 1A expression was assessed in astrocytes and human brain autopsy sections using western blotting, immunocytochemistry, and immunohistochemistry. siRNA-mediated downregulation was performed to assess its loss of function. To assess the cell activity, live-cell calcium imaging was performed on ATP-stimulated astrocytes using a confocal microscope. HIV-1 Tat B expression vector was used to induce astrocyte reactivity, after which gene and protein expressions were assessed using qPCR and western blotting; cytokine release was measured using flow cytometry and glutamate release was assessed using enzymatic activity. TUNEL assay was performed on neurons treated with the astrocyte-conditioned media. Small RNA-sequencing and qPCR assays were performed to list miRNAs differentially regulated as a result of HIV-1 Tat transfection. Transfection with mimic and inhibitor against selected miRNA and luciferase assay was performed to confirm the miRNA regulation.ResultsWe report Coronin 1A expression in human primary astrocytes and autopsy brain sections, and that it plays activity-dependent roles by facilitating Calcium mobilization from the intracellular stores. HIV-1 Tat, a potent neurotoxicant that turns astrocytes reactive, augments Coronin 1A expression, apart from affecting GFAP and pro-inflammatory molecules. Also, the autopsy brain tissue of HIV-1 infected individuals has higher Coronin 1A expression. Downregulation of Coronin 1A attenuated the HIV-1 Tat-induced deleterious effects of reactive astrocytes, measured as upregulated GFAP expression, enhanced release of IL-6, and Glutamate and hence reduced astrocyte-mediated neuroinflammation. Our findings also suggest that out of a pool of dysregulated miRNAs studied by us, hsa-miR-92b-5p regulates Coronin 1A expression under the effect of HIV-1 Tat. ConclusionThese findings highlight the novel roles of Coronin 1A in regulating astrocyte activity in stimulated conditions and astrocyte reactivity observed in HIV-1 neuropathogenesis.
