Conceptualización de los contratos inteligentes o autoejecutables basados en la tecnología blockchain y su encuadre en el ordenamiento jurídico español
Authors: Castellano García Adoración
Published: December 2021

En el sector de la contratación electrónica, desde hace unos años se ha potenciado el uso de los denominados contratos inteligentes o autoejecutables, debido a que el desarrollo de la innovadora tecnología de la cadena de bloques ha revolucionado su ámbito de aplicación. Como consecuencia del auge experimentado, desde el punto de vista jurídico se han planteado distintos interrogantes tendentes a dilucidar si son contratos que deben regirse por la normativa legal vigente o no. Y ello en base, tanto a su proceso de formación y perfección, como a las particularidades que caracterizan su ejecución, en la cual, destacan instrumentos de pago electrónicos como las criptodivisas.

A Privilege not a Choice: Transnational Support Networks of Asylum Seekers and Expatriates
Authors: Hoór Dorottya
Published: December 2021

The article explores how different factors shape migrants’ transnational social fields and support networks through a comparative study of two different groups of migrants—asylum seekers and expatriates—in Budapest, Hungary. To do so, the study employs a parallel mixed‐methods social network design by combining personal network data with qualitative data based on interviews and ethnographic fieldwork with thirty‐three migrants in the aftermath of the 2015 refugee crisis. The article presents three key findings: First, it finds that asylum seekers’ and expatriates’ networks differ on several key characteristics, as asylum seekers’ close personal networks are less efficient, smaller in size, and show a remarkable lack of friendship and transnational support ties. Second, it also finds that asylum seekers have limited access to social support and, especially so, to financial and emotional support. Lastly, using multi‐level models, the article also demonstrates how migrants’ legal status and the transnationality of their support ties affect their access to financial support, as well as how their gender and legal status shape their access to emotional support. These findings illustrate how migrants’ individual opportunity structures affect their transnational practices alongside their access to social support, while also highlighting the importance of several individual and contextual factors which contribute to the diverse integration processes of migrants.
Differentiated Embedding and Social Relationships Among Russian Migrant Physicians in Finland: A Narrative Socio‐Analysis
Authors: Habti Driss
Published: December 2021

Migrants’ processes of (dis)embedding in local and transnational social networks have received growing attention in recent years, but most research focuses on low‐skilled migration. This study explores the affordances and challenges that Russian physicians, as a high‐skilled migrant group in Finland, experience in these processes in work and non‐work domains. Based on semi‐structured biographical interviews with 26 Russian physicians, the study employs Bourdieu’s socio‐analysis to analyze their narratives. The results reveal that Russian migrant physicians negotiate and experience differentiated embedding across work–life domains in local and transnational contexts. They mostly develop collegial relationships with Finnish colleagues and benefit from fulfilling professional relationships in the work domain. However, alongside time and efforts needed for building social ties, various factors often impede friendship making and socialization with locals beyond the work domain. These physicians cope with individual life circumstances through their enduring and supportive relationships with their Russian relatives and colleagues–friends. These results indicate that high‐skilled migrants have a greater opportunity to connect professionally with locals than low‐skilled migrants, but experience similar challenges to the latter in building close personal relationships.
Interpersonal Antecedents to Selective Disclosure of Lesbian and Gay Identities at Work
Authors: Rengers Julian M. , Heyse Liesbet , Wittek Rafael P. M. , Otten Sabine
Published: December 2021

Lesbian, gay, and bisexual (LGB) employees’ sexual identitymay be considered a concealable stigmatised identity. Disclosing it to others at work could potentially lead to discrimination and rejection, hence threatening their inclusion. Therefore, they may hide their sexual identity instead, which may then come at the cost of, e.g., guilt for not living authentically. However, disclosure is a continuum—rather than a dichotomy—meaning that LGB workers may decide to disclose selectively, i.e., telling some, but not all co‐workers. Most literature on disclosure focuses on the interplay between intrapersonal (e.g., psychological) and contextual (e.g., organisational) characteristics, thereby somewhat overlooking the role of interpersonal (e.g., relational) characteristics. In this article, we present findings from semi‐structured, in‐depth interviews with nine Dutch lesbian and gay employees, conducted in early 2020, to gain a better understanding of interpersonal antecedents to disclosure decisions at work. Through our thematic analysis, we find that LGB workers may adopt a proactive or reactive approach to disclosure, which relates to the salience of their sexual identity at work (high/low) and their concern for anticipated acceptance. Other themes facilitating disclosure include an affective dimension, being in a relationship, and associating with the employee resource group. We demonstrate the importance of studying disclosure at the interpersonal level and reflect on how our findings relate to literature on disclosure, authenticity, belonging, and social inclusion of LGB individuals at work.

Authors: Biai Alexandre , Costa Cilmara Talyne de Araújo , Luz Lucas Nunes da , Marques Virna Braga , Pereira Ana Carolina da Silva
Published: December 2021

O amendoim é uma cultura agrícola amplamente conhecida no Brasil. O consumo in natura é o principal meio de aproveitamento da produção. Originário da América do Sul é uma das oleaginosas mais cultivadas em todo mundo, em razão da grande variabilidade nas formas de consumo, sabor e adaptabilidade de produção em áreas tropicais e subtropicais. O objetivo do presente trabalho foi avaliar o desempenho das características agronômicas de crescimento e produtividade de cinco acessos de amendoim sob adubação orgânica. O trabalho foi conduzido no câmpus das Auroras da Unilab, entre abril e julho de 2018. Foi utilizado um delineamento estatístico de blocos casualizados (DBC) com cinco tratamentos e seis repetições. Foram analisadas as características agronômicas: Dias de Emergência (DE), Altura das Plântulas (AP), Números de Ramos, Número de Vagens por Planta (NVP), Número de grãos por Planta (NGP), Peso de massa fresca (PMF), Peso de Massa Seca (PMS) e Peso de 100 grãos (P100G). Os dados foram submetidos à análise de variância em delineamentos de blocos casualizados com três repetições. Os quadrados médios foram comparados pelo teste F e as médias pelo teste de Tukey a 5%. Os acessos Unilab 130 e Unilab 138 destacaram-se em peso e produção de vagens sendo bons genótipos de porte rasteiro. Unilab 107 e 124 situaram-se como intermediários aos demais acessos em relação à produção e podem ser considerados para produção desde que atendidas suas exigências de cultivo. Unilab 130 apresenta-se como um bom genótipo a ser utilizado como genitor em programas de melhoramento.

Published: December 2021

O complexo de Sigatoka é umas das principais doenças da bananeira e a aplicação de agrotóxicos é uma importante ferramenta de controle dessa doença. Porém, a demanda por estratégias de controle de doenças de plantas mais seguras tem motivado a busca por produtos alternativos. Nesse sentido, o objetivo desse trabalho foi estudar o efeito de preparados de plantas nas interações bananeira – Pseudocercospora sp. Para isso, analisou-se o efeito de diversas concentrações de extratos hidroalcoólicos (capim limão miúdo, guaco e quebra-pedra), óleo essencial (capim limão miúdo, eucalipto e melaleuca) e hidrolato (capim limão miúdo) no número de colônias de P. fijiensis e P. musae em meio de cultura. Além disso, foi estudada a eficiência dos óleos essenciais no controle do complexo de Sigatoka em folhas de bananeiras naturalmente infectadas. Verificou-se que os óleos essenciais, o hidrolato e os extratos hidroalcoólicos inibiram em até 100%, 76% e 52%, respectivamente, o crescimento de P. fijiensis in vitro. Os óleos essências e o extrato de quebra-pedra inibiram em 100% o crescimento in vitro de P. musae. Porém, nenhum óleo essencial reduziu os sintomas de Sigatoka em de bananeira.

Published: December 2021

A astrapeia, Dombeya wallichii (Lindl.) Baill, é uma espécie ornamental florística, e, por possuir grande quantidade de néctar e pólen tem importância apícola. A propagação da espécie ocorre por sementes e a estaquia pode surgir como alternativa para a formação de mudas. O objetivo do estudo foi avaliar diferentes épocas e substratos na produção de mudas de astrapeia como planta alternativa na apicultura. O estudo foi realizado no Viveiro Florestal da Universidade Tecnológica Federal do Paraná, campus Dois Vizinhos, Paraná. Coletaram-se da base de uma matriz ramos (brotações) em diferentes épocas do ano e confeccionaram-se estacas de 10 cm de comprimento. O delineamento experimental foi o DIC (Delineamento inteiramente casualizado) em um sistema fatorial 3 X 3, com três épocas de coleta dos ramos (inverno, primavera e verão) e três substratos (substrato orgânico comercial, solo de barranco e mistura dos dois substratos), com quatro repetições de dez estacas por parcela. Plantaram-se as estacas em tubetes de polipropileno de 120 cm³, mantidas em bandejas na casa de sombra. Aos 75 dias, avaliou-se porcentagem de estacas enraizadas, com calos, mortas, vivas, com brotações, número e comprimento médio de raízes e número médio de brotações. O substrato orgânico comercial e o verão destacaram-se favoravelmente à produção de mudas de astrapeia, sendo essa, portanto, a melhor opção para os apicultores obterem plantas da espécie.

Published: December 2021

O objetivo do presente trabalho foi enquadrar o Estado do Espírito Santo no modelo de Holdridge, comparando-o com o sistema de Köppen e a distribuição fitogeográfica. Com as médias municipais de biotemperatura, precipitação, relação de evapotranspiração potencial, altitude e latitude, determinaram-se as zonas de vida de cada um dos 78 municípios do Estado. Obtiveram-se dados a partir de bases cartográficas oficiais e registros de no mínimo 25 anos coletados em estações meteorológicas e postos pluviométricos. Processaram-se as informações com programa FoxPro e o enquadramento das classes climáticas se fez por intermédio de diagramas. Os resultados revelaram seis zonas de vidas: floresta úmida/seca subtropical basal (52%), floresta úmida subtropical basal (25%), floresta úmida/seca tropical premontana (13%), floresta seca/úmida subtropical basal (7%), floresta úmida subtropical montana baixa (3%) e floresta úmida tropical premontana (1%). Três zonas de vida se correlacionaram significativamente com três tipos climáticos de Köppen, sendo que o fator relevo foi o principal causador da recorrência espacial. A fitogeografia não se correlacionou significativamente com a classificação do sistema de Holdridge, porém seriam necessárias mais pesquisas para robustecer esta constatação.

Authors: Visoni Bruno Mendes , Pires Tatiani Botini
Published: December 2021

Estudos limnológicos são de grande importância para as pisciculturas uma vez que a produção de peixe está diretamente correlacionada com a qualidade da água. Vale ressaltar que a qualidade da água não só contribui para o desenvolvimento do peixe, mas é um fator primordial nos indicadores econômicos. Então, teve-se como objetivo identificar as características limnológicas em três pisciculturas da região do Vale do Guaporé, a fim de caracterizar o padrão de qualidade da água. O estudo ocorreu entre o período de dezembro de 2014 a dezembro de 2015, com coletas mensais. As variáveis acompanhadas foram Temperatura da água, Pressão, Oxigênio Saturado, Oxigênio Dissolvido, Condutividade específica, Condutividade, Coeficiente de atenuação vertical da radiação e potencial hidrogeniônico. A correlação das três pisciculturas sobre a temperatura não apresentou estatisticamente diferença uma da outra. Os problemas encontrados representam falhas na prática de manejo e não da condição do recurso hídrico disponível. Através da caracterização das condições limnológicas das pisciculturas situadas na região do Vale do Guaporé conclui-se que esta região apresenta todas as condições ambientais propícias para o cultivo de peixes nativos.

Datados ambos en 1785, uno de ellos consiste en el informe sobre una solicitud del V marqués de Valdecarzana, pariente lejano del gijonés, acerca de la imposición de un censo en Valencia; el otro tiene por objeto informar sobre los daños causados por un incendio en la parroquia de Sebares, en el concejo asturiano de Piloña, y estima favorablemente la petición de un vecino para que se le compensen económicamente sus pérdidas.
An innovation adoption model of licensing-in for US start-ups
Authors: Power Bernadette , Reid Gavin C.
Published: December 2021

Using the Kauffman panel dataset of US start-ups, we analyse the key determinants oflicensing-in adoption. Licensing-in entails an intellectual property contract between the licensor(e.g. upstream established firm) and licensee (e.g. downstream start-up) aiming to bring aninnovation to market rapidly. Assuming maximizing of the owner’s managerial utility in thestart-up years, we explain licensing-in adoption through firm characteristics like size, R&D andcapital structure, as well as other IP types, and controls for year and regional fixed effects, usingpanel probit estimation with adjustments for sample selection bias and endogeneity. We findkey determinants of licensing-in to be owners’ equity, product (rather than service) sales andR&D spend; and then comment on their policy implications for business incubation.
Monitoring and prospects for conservation and rational use of the resources of the Eurasian beaver (Castor fiber Linnaeus, 1758) on the example of the Samara Region
Authors: Antipov Vitaly Vasilievich , Dvornikov Mikhail Grigorevich
Published: December 2021

The paper examines characteristics of the Eurasian beaver population (Castor fiber Linnaeus, 1758) on territories with different anthropogenic load. Monitoring the beaver population and habitat, including the landscape basis and natural zoning with the allocation of natural, natural-anthropogenic and anthropogenic territories as natural ecological systems allows you to manage and rationally use the resources of these animals. Previously there were mainly natural territories in the studied region, however with the growth of the human population and its economic activity their properties have changed. According to biotic criteria, geochemical circulation, significant (formerly natural) territories functionally already correspond to natural-anthropogenic and anthropogenic objects, since the supply of fodder, population density and density of animals have changed. According to natural zoning, taking into account the identified changes in the habitat of beavers (by biotic criteria), we have examined their territorial distribution as well as the number of settlements in various natural objects of the region. On the studied rivers the density of the beaver population in the channel decreases in the following order: natural territory natural-anthropogenic anthropogenic, but the indicator of private abundance (the density of animals on the territory where beavers live directly) and aggregation (crowding of individuals) increases. The population density of the river bed of the studied rivers by beavers on anthropogenic territories is from 0,93,7 individuals/km, which is lower than on natural and natural-anthropogenic territories, where this indicator is from 1,5 to 6 individuals/km. The length of the river bed, where beavers live directly, without taking into account significant buffer zones, varies in natural areas from 60 to 100%, which is more than in areas with anthropogenic load, where this indicator in the study area decreases to 40%. A decrease in the size of river channel sections suitable for beaver colonization leads to overcrowding (aggregation) of individuals. Compared with the total density of beaver population in the river channel 0,93,7 individuals/km of the channel (excluding the Kondurcha River 6 individuals/km of the channel) the population density, locally, on anthropogenic and natural-anthropogenic territories increases to 47,5 individuals/km.

Published: December 2021

The presence of agrocoenotic factors constantly acting on segmental (weed-field) communities leads to a high level of community invasion a potential opportunity to accept new species. In many cases, it is through synanthropic communities that invasions of alien species occur in the Urals, which cause significant damage to both agriculture and the entire economy of the region as a whole. The aim of investigation is to survey and identify the coenotic diversity of communities involving alien species in the steppe zone of the southeastern part of the Orenburg Region. The paper provides data on weed communities with the participation of Acroptilon repens, the Sisymbrium volgense and Artemisia sieversiana. Communities were identified in spring wheat crops in the southeast of the Orenburg Region (Dombarovsky and Svetlinsky administrative districts). Communities develop on dark chestnut soils in arid conditions of the steppe zone. As a result of a synaxonomic analysis, communities were classified into three new variants of the association Lactucetum tataricae Rudakov in Mirkin et al. 1985 previously described in the Republic of Bashkortostan. Perennial weed species prevail in the agrobiological spectrum of the coenoflora nucleus of the studied segetal communities, the share of which is 70%. The most active of them are root-sprung perennials, which are found with high constancy and often dominate: Acroptilon repens, Fallopia convolvulus, Cirsium arvense, Convolvulus arvensis, Lactuca tatarica, Euphorbia virgata. Using the indirect ordination method (DCA), the features of ecological differentiation of communities are demonstrated. The studied phytocoenoses are associated with the driest habitats with poor soils.
Pezmogty 3B – a small Neolithic dwelling on the Middle Vychegda (Komi Republic)
Authors: Karmanov Viktor Nikolaevich
Published: December 2021

The paper publishes the results of a study of complex B of Pezmogty 3 site. The author has studied traces and remains of a depressed small dwelling with an excavation area of 81 m. The spatial distribution of artefacts, faunal remains and their association with deposits of different genesis have been analysed. It is defined that the studied structure was rounded in the plan, 3,03,5 m in diameter, 79,5 m in area, and, probably, a cone-shaped roof. The assemblage contains stone objects, fragments of ceramic ware and indeterminable items, fragments of calcified bones. The morphology of the flint arrowheads; the signs of secondary bifacial thinning technology; the ceramic pots, made of clay with an admixture of silt and decorated with a comb-pit ornament, allow us to attribute these materials to the Lyalovo culture in the European North-East and date them to the first half of the V millennium B.C. Until now, the most informative data for the study of this culture in north-eastern Europe were the remains of medium and large dwellings with an area of 26 to 100 m, so the published materials expand our understanding of the way of life and house-building traditions of the Middle Neolithic people of this region.
Optimization of general education networks structure in rural areas of the Russian Federation and the Samara Region from the late 1990s to 2020
Authors: Eremin Sergey Vladimirovich
Published: December 2021

This paper discusses the optimization of rural educational networks structure in the Samara Region and Russia from the late 1990s to 2020. Documents of the federal level that contributed to the development of the countrys educational system, including the development of a general education network in the countryside, are presented. The dynamics of changes in the number of general educational organizations in the country in comparison with the number of schoolchildren for the period from 1995/1996 academic year to 2019/2020 academic year is given. The author compares approaches to the optimization of rural general education network structure used in the experiment on restructuring the network of general educational institutions located in rural areas which was conducted in the 2002/2003 and 2003/2004 academic years and during the implementation of complex projects for education modernization by the Russian regions in 20072009. On the example of the Samara Region, differences and similar moments of rural general education network structure optimization in this region with all-Russian trends are considered. The basic regional principles of optimization are revealed. Models of changes in the structural elements of the general education network of the Samara Region in comparison with the models used in the framework of the experiment on restructuring the network of rural schools are presented.

The paper is devoted to the problem of environmental education implementation in modern conditions through formation of ecological consciousness and ecological culture of students personality within the educational process and outside. To solve this problem it is necessary to develop new approaches to the training of prospective environmental educators and their professional competence development. Its also necessary to control and evaluate all the main components of professional competence. In the structure of the teachers professional competence the authors of the paper include a set of theoretical knowledge and their application in various pedagogical situations, as well as value orientations and a set of indicators of the teachers culture: speech, communication style, attitude to himself/herself and his/her activities and to other fields of knowledge, etc. At the same time, the system of professional education of modern teachers consists of subject training as well as psychological, pedagogical and methodological training, the purpose of which is to form the ability to organize the educational process on principles of personality-oriented interaction. In the structure of professional and pedagogical competence of bachelors majoring in Ecology, it is possible to distinguish meaningful, value-motivational and operational-activity components. The authors also consider possible ways of monitoring and assessment of pedagogical competence development among bachelors majoring in Ecology for pedagogical activity, their professional competence and training.
Historical and cultural standard and teacher’s professional training within the course of the civil identity formation (formulation of the problem)
Authors: Malkin Stanislav Gennadyevich
Published: December 2021

The paper is devoted to the role of the state educational policy within the course of the Russian civil identity formation. The focus of the study is on the evolution of the aims of the authorities in matters of the historical education and historical memory, their norm-legal regulation and institutional support, as well as real educational practices. The introduction of the historical and cultural standard for teaching the school course of the history is considered as a collective attempt by the authorities and society to lead historical and educational policies to a common denominator in terms of the content and value. A special accent in the paper concerns the problems of the teacher professional training for the implementation of the state historical and educational policy of the Russian Federation within given framework, considering the specifics of the contemporary informational space. It attracts attention to the close ties between information wars and historical policy, in the context of the attempts to reconsider the results of the Second World War especially, keeping in mind its effects for the transformation of the civil identity and the changes of position the Russian Federation held on the international arena. Both methodological and organizational restrictions were identified in secondary and higher schools, which have a significant impact on the formation of civil identity through historical education, both at the stage of training pedagogical personnel and in the process of studying the school course of the history.

Published: December 2021

Gospodarski prosperitet maritimnih regija ovisan je o razvoju nautičkih luka i s njima povezanih aktivnosti. Nautičke luke i nautički turizam važni su za stvaranje radnih mjesta i prihoda te za ukupni društveni i ekonomski razvoj obalnih i otočnih zajednica. Štoviše, visoki prihodi koje generira nautički turizam imaju značajan udio u ukupnim prihodima od turizma kao glavnom izvoru prihoda u hrvatskom gospodarstvu. Stoga ovaj rad istražuje ukupne prihode nautičkih luka predlažući model koji se sastoji od triju koraka: 1) klasifikacije ulaznih varijabli u tri kategorije: ekološku, društvenu i ekonomsku, sukladno temeljnim aspektima održivog razvoja; 2) primjene metode glavnih komponenti na svaku kategoriju u svrhu oblikovanja novih varijabli kao predstavnika kategorija; 3) primjene metode višestruke regresije za analizu ukupnih prihoda. Statističkom analizom i usporedbom rezultata pokazuje se da predloženi model dobro iskazuje ukupne prihode, r2 = 0,92, uz potvrđenu statističku značajnost. Analiza i predloženi model omogućuju objektivnije razumijevanje promatranog sustava, analizu njegova održivog razvoja i donošenje odluka.

Published: December 2021

The twelfth issue of On Education is devoted to attempts to tame technology use in education. It asks what challenges educational institutions face from instructional technologies, and what answers have been and are being found. It asks to what extent programmers, software developers or entrepreneurs themselves are able to tame the technologies they want to sell to schools. It discusses the role of teachers, activists, policy makers, and administrators in resisting, regulating, or affirmatively embracing educational technologies.
Rewilding Technology
Authors: Macgilchrist Felicitas
Published: December 2021

This paper is rooted in the ecological crisis of our contemporary world. Rather than rejecting educational technology (edtech) as too environmentally damaging to use, it draws on critical utopian approaches, feminist science fiction and conservation projects to suggest ‘rewilding’ as a frame for designing and using edtech with a view to ameliorating technology’s long-term inequitable planetary impact. After briefly describing projects for rewilding nature, the paper turns to the specifics of rewilding edtech. It first highlights pragmatic suggestions for more
sustainable edtech practices. It then suggests that the concept of ‘sustainability’ limits current practices, and proposes that a more radical and utopian rewilding can herald an education beyond sustainability. Rewilding edtech prioritises decelerating and degrowth, regenerating and relating, hospicing dying worlds and birthing new possibilities.

Harnessing Technology for Cultural Transformation: A Case Study From South Africa
Authors: Tshuma Nompilo
Published: December 2021

Taming the technology used for teaching and learning in higher education can take different forms. These taming activities are dependent on the context – and critical issues that affect higher education within those contexts – as well as the agency of academics to address those issues. The focus of this paper is on one such context, where cultural transformation is a key theme in higher education. In this paper, I reflect on how technology has been harnessed by academic change agents to challenge cultural norms while recognising diversity within their classrooms.
Regulation of pluripotency genes by CX3CR1 in cancer cells
Authors:   , Castelli Maria Sofia , Fatatis Alessandro
Published: December 2021

Prostate and breast cancers are among the most frequently diagnosed malignancies in the United States, leading to approximately 60,000 deaths every year. Although localized disease has a high survival rate, over 30% of the patients with either form of tumor develop metastatic recurrence over time. Metastatic disease remains incurable, accounting for most cancer-related deaths. Evidence suggests that while most cancer cells within a primary tumor lack the ability to initiate new tumors, a small group of cells known as cancer stem cells (CSCs) can initiate metastatic lesions and sustain their growth. CSCs are characterized by stemness features, which are mediated by the expression of pluripotency transcription factors, including OCT4a and NANOG. Recent evidence suggests that chemokine receptors may play an important role in the regulation of cell stemness. Our lab has previously demonstrated that the chemokine receptor CX3CR1 is implicated in tumor progression and metastasis in prostate and breast cancers. Furthermore, our studies suggest that prostate and breast cancer cells with high CX3CR1 expression (CX3CR1High) display stem-like features and express pluripotency genes. In contrast, cancer cells with low CX3CR1 expression (CX3CR1Low) do not display stemness features but undergo phenotypic plasticity, reacquiring the expression of CX3CR1 and pluripotency genes over a period of time. In this study, we set to determine if CX3CR1 is involved in regulating the expression of pluripotency genes during phenotypic plasticity. To this end, we used flow cytometry to sort prostate and breast cancer cells based on their CX3CR1 expression levels, and then cultured CX3CR1Low cells over a period of time to assess the timeframe for the re-expression of CX3CR1, OCT4a and NANOG. We also cultured these cells in the presence of a CX3CR1 small molecule inhibitor, FX-68, in order to assess the effect of blocking CX3CR1 in the re-expression of pluripotency genes. Our preliminary results show that both prostate and breast cancer CX3CR1Low cells increase their expression of CX3CR1, OCT4a and NANOG following in vitro culture, and this re-expression appears to be impaired when CX3CR1 is blocked. These results suggest that CX3CR1 may be involved in regulating its own expression and the expression of pluripotency genes and may thus play a role in dictating stemness features and promoting metastasis initiation. Our study provides further evidence for the involvement of CX3CR1 in cancer progression and its potential as a therapeutic target to treat metastatic disease.

The purpose of this study is to investigate the impact of a startup's visionary leadership on partner alignment, knowledge sharing and partner performance in the context of a partner network model. We argue that startups are challenged by a lack of sales in the initial stages and thereby resulting in high rates of mortality. Drawing upon the theory of visionary leadership, we suggest that knowledge sharing between a startup and network partner will have a positive relationship to partner performance. Secondly, we argue that visionary leadership would have a positive impact on partner alignment. Thirdly we posit that partner alignment would moderate the relationship between knowledge sharing and partner performance. Finally, we argue that partner alignment would have a positive relationship with partner performance in such a model. To support our hypotheses, we identified a startup that operates with such a partner model for our study. The startup works with network partners across the globe and the network partners collaborate with the startup to enhance its sales effort. We conducted a field experiment (n=62) to test our hypotheses. The partners were divided into intervention and control groups as part of the experiment. Through logs and self-report surveys, we gathered data on visionary leadership, alignment, knowledge sharing and partner performance. Results, implications and limitations of the study are discussed.

This thesis aims to explore the theater and audiences, including how theaters have attracted and maintained audiences during the COVID-19 pandemic. Interviews were conducted with staff members at three different theaters throughout the United States: Playhouse on the Square, Dayton Live and Shea's Performing Arts Center. Interviews addressed analysis and research of the theaters' target audiences, marketing strategies and participation, and the barriers theaters confront when attracting audiences. Overall, the findings reveal that theaters have developed new marketing strategies to attract audiences during the pandemic. Social media and online performances have functioned as a bridge between theaters and audiences, with theaters continuing to provide performances which the audience can watch at home. This case study could serve as a reference for theaters to attract and maintain audiences during the pandemic or future crises that interrupt in-person performances.

Objectives: In order to deeply analyze the feasibility of reducing pressure and increasing production of coalbed methane wells in nano-porous coal seams and clarify the principle of well selection. Methods: The sensitivity of bottom hole flowing pressure to coalbed methane
production is analyzed by establishing productivity equation in stable production period of coalbed methane wells. Combined with the numerical simulation method, the drainage and production effect of L-1 well in the Block A is simulated after reducing the flowing pressure at the bottom of
the well. Results: The results show that for CBM wells that have been put into production, the effect of increasing the production can be achieved by reducing the bottom hole flowing pressure, and when the bottom hole flowing pressure is large, reducing the bottom hole flowing pressure
can obtain a larger increase in gas production. The cumulative gas production of Well L-1 can be increased by 110x104m3 compared with the previous measures, and the increase rate can reach 85%. Conclusion: Combining with the pressure-reducing and increasing production wells in the Block
A, the applicable conditions for pressure-dropping and increasing production to increase the production of CBM wells are proposed, that is, continuous and stable drainage and production, and there is a certain height of liquid column between the moving liquid level and the coal roof before
operation.

Published: December 2021

Objectives: Power demand-side construction projects should consider the potential environmental damage and formulate feasible measures to increase the willingness of participants to take the initiative actions. Methods: This paper innovatively takes the concept of environmental
loss cost into the discussion of the project environmental governance issues, and applies the potential cost expenditures of both principal parts to the study of game strategy equilibrium problems. Results: And then, the evolutionary game analysis method is used to discuss the balance
of supervision and incentives between government departments and power companies under different strategic choices. Considering the environmental damage cost, the research suggests that taking measures to improve the efficiency of government supervision, reducing supervision costs, or increasing
the punishment of power enterprises for delaying responsibility will guide the government’s strategy to evolve in the direction of strengthening supervision. Conclusion: Increasing the incentives or penalties for power enterprises of taking active responsibility of environmental
will also help improve the environmental governance of power demand-side projects. Finally some research perspectives are brought to the attention of readers.

Published: December 2021

Objectives: Cross-cultural communication lays the foundation for sustainable development education. In order to further improve the level of cross-cultural awareness of college students in China, a recommendation algorithm based on cross-cultural communication comparison model
is proposed. Methods: The algorithm uses the keywords with high weight in the recommended items as the attribute characteristics of the recommendation items, and then recommends the items with the closest vectors (the highest score of the vector calculation with user characteristics)
to the users. Results: TF-IDF method is used to calculate and calculate the keywords with high weight in intercultural communication mode as describing user characteristics, and these keywords are used as describing vector of user characteristics, so as to construct the intercultural
awareness model of College students. Finally, APRIORI ALL algorithm is used to train and test the model. Conclusion: The test results show that the error is less than 5%. The experimental results show that the proposed algorithm is effective. The intercultural awareness model can improve
the intercultural communicative competence of college students and provide a reference for English intercultural teaching in basic education stage.
