The Manifestation of Terrorism and Extremism in Prisons
Authors: Brunová Markéta , Vegrichtová Barbora
Published: March 2020

The paper deals with prison facilities from the perspective of the security threats of radicalization and terrorism. Prisons are continuously assessed as an ideal recruitment pool for extremist and terrorist organizations. Prison environment concentrates various persons with criminal past and with the tendencies to accept different ideological doctrines or radical interpretations of religions. Many of prisoners suffer from stress, lack of social and family support, uncertain future, depressions and frustration. Such factors could initiate or accelerate radicalization process in correctional facilities. This security problem is in contemporary days discussed in many European countries. All security experts and academic institutions came to the fact, that the crucial attribute of this issue is prevention and appropriate identification of the indicators of radicalization. The paper gives an overview of the most significant findings in this field, summarizes the experiences of Czech Republic and gives examples of good practices.

Apego a Deus: revisão integrativa de literatura empírica
Authors: August Hartmut , Esperandio Mary Rute Gomes
Published: March 2020

Este artigo apresenta uma revisão da literatura empírica sobre apego a Deus. O método utilizado foi a revisão integrativa, com levantamento nas bases BVS, CINAHL, Periódicos CAPES, PsycARTICLES, PubMed, SciELO e SocINDEX. Após exame das 254 publicações encontradas, 62 estudos foram selecionados para análise, categorizados em cinco grandes temas: “construção ou validação de escalas”, “ciclos da vida”, “saúde mental”, “experiência religiosa” e “aconselhamento e cuidado espiritual”. O apego parental influencia na maneira como a pessoa irá construir ou não uma relação de apego a Deus. O apego a Deus pode ser um meio para atenuar o sofrimento e para reparar os modelos internos de funcionamento da pessoa. Pessoas com apego seguro a Deus apresentam um aumento sadio da espiritualidade e adotam comportamentos que favorecem a saúde física e emocional. Pessoas com apego inseguro a Deus apresentam instabilidade na espiritualidade e reportam mais aflição, podendo sofrer um declínio na saúde mental. Os conceitos de um Deus que se importa e cuida podem ser empregados para promover maior autonomia e autoconfiança da pessoa. Considerando a importância da religiosidade no contexto cultural brasileiro, o aprofundamento do tema seria de grande relevância para os campos da Teologia, da Psicologia e das Ciências das Religiões.
A Teologia na árvore das áreas de conhecimento
Authors: Alves César Andrade
Published: March 2020

O advento da Ciência moderna e seu método expôs o método teológico a novas exigências. O objetivo do artigo é justificar metodologicamente a presença da Teologia entre as disciplinas científicas. A metodologia é a da pesquisa bibliográfica. O artigo evidencia os elementos em comum entre o método científico e o teológico e suas peculiaridades, com ênfase nas premissas de ambos. Essa abordagem é inédita na literatura metodológica. Isso permite, por um lado, evidenciar os elementos em comum. Primeiro, o ato de fé. Em Ciência faz-se um ato de fé naquelas premissas do método, pois para elas não há demonstração cabal, nem estão elas abertas à falseabilidade. Tal abordagem é também inédita. São evidenciadas oito dessas premissas do método científico. Uma das premissas é a da natureza pura, cuja origem é examinada. Essa premissa é pela primeira vez trazida à reflexão sistemática sobre o método científico. Segundo, o seguimento da sequência de cinco passos metodológicos. Por outro lado, o artigo evidencia os elementos distintivos entre os dois métodos. A adesão a uma confissão religiosa é a principal diferença epistemológica entre a Teologia e a Ciência, em particular as Ciências da Religião. Para essas isso traz consequência.
Presídias dos terceiros do Carmo de Vila Rica: territorialidade e rede confraternal em Minas Gerais, 1744-1848
Authors: Andrade Francisco Eduardo de
Published: March 2020

A pesquisa trata da configuração institucional da Ordem Terceira do Carmo da capital político-administrativa do território minerário, Vila Rica ou Ouro Preto, através das suas filiais, as presídias (presidências locais), cuja disseminação ultrapassou os limites da capitania/província de Minas Gerais, no interior brasileiro. As presídias forneceram à sede-matriz da Ordem Terceira rendimentos acrescidos (pagamentos, doações, concessões) que não eram acessíveis às irmandades reduzidas a uma jurisdição paroquial. As filiais da Ordem foram os dispositivos fundamentais de integração local dos associados (agentes do comércio ou emigrados) e da instituição da fraternidade, com papel destacado nas alianças de amizade e de parentesco. Essa associação religiosa de abrangência territorial, justaposta à teia de freguesias das Minas (matrizes e capelas), conformou uma elite político-econômica e as identidades dos agentes de poder (brancos, senhores, autoridades políticas, militares), contribuindo para forjar noções de pertencimento comunitário e de reconhecimento de grupo (conforme o estamento). Através da difusão das presídias, ademais, pode-se apreender o mercado dos bens simbólicos relacionados às práticas devocionais carmelitanas.

Religião, memória e cultura: perspectivas teóricas a partir de Maurice Halbwachs
Authors: Teixeira Alfredo
Published: March 2020

Os grupos humanos desenvolveram toda a espécie de recursos mnemotécnicos e sistemas de registo para facilitar o acesso posterior a algo que foi descoberto, produzido e adquirido. A religião, na medida em que condensa uma parte das experiências humanas de construção da coletividade, é um laboratório relevante no que à construção social da memória diz respeito. A conservação da memória implica sempre estratégias de inovação. Assim, as tradições religiosas da humanidade dão testemunho de um longo trabalho de (re)construção de uma certa perspetiva sobre o mundo (cósmico e social), sobre os modos de nele e sobre ele agir, projetando as pontes para outros «mundos». Este ensaio parte da noção de memória, nas suas aceções socioantropológicas, para compreender a religião como fenómeno cultural em várias das suas dimensões estruturantes: propagação, distribuição, durabilidade, transmissão. Esta via de teorização alicerça um percurso que, tendo como ponto de partida a obra de Maurice Halbwachs, visa estabelecer um quadro interpretativo para um duplo problema: o lugar da religião enquanto memória das culturas; os processos de memoração como cerne da atividade religiosa.
Fim de uma ordem: natureza, lei divina, feminismo
Authors: Rosado-Nunes Maria José Fontelas , Carranza Brenda Maribel
Published: March 2020

Este texto orienta-se pela hipótese de que o magistério da Igreja Católica e os estudos de gênero operam com pressupostos epistemológicos distintos ao formularem a noção de natureza humana e sua força analítica transcende as especulações acadêmicas e os âmbitos teológicos. Para a argumentação dessa proposta analisam-se algumas abordagens sobre a compreensão da natureza nos estudos de gênero e nos documentos pontíficios. Constata-se que longe de ser apenas um embate epistemológico o que emerge é a relevância política da categoria de gênero e sua intrínseca relação com o feminismo. Ainda, discute-se como deslizam os léxicos científicos e doutrinais para a sociedade onde há um confronto político entre dois movimentos: o feminismo e as campanhas antigênero, essas últimas com dimensões transnacionais que ultrapassam os grupos conservadores do cristianismo que as lideram.
Teologia negra: a fenomenologia do damné como caminho de humanização
Authors: Caldeira Cleusa
Published: March 2020

Com este texto busca-se contribuir com os Estudos da Religião a partir da reabilitação da tradição do pensamento negro crítico e, ao mesmo tempo, entabular um pensamento teológico antirracista e despatriarcalizado. Assume-se, pois, a crítica decolonial que coloca em relevo o racismo epistêmico e ontológico que segue invisibilizando e aniquilando uma porção considerável da humanidade. No marco do diálogo epistemológico Norte e Sul, segue-se a proposta de uma ontologia relacional da gratuidade propugnada pela teologia pós-moderna niilista latino-americana, para pensar o fim da violência intersubjetiva e a instauração da intersubjetividade, isto é, o estágio harmonioso do mútuo reconhecimento. Intui-se, entretanto, que não é possível pensar em ontologia relacional fora da fenomenologia dos damnés da terra (Fanon), isto é, sem a assunção da exterioridade da Modernidade. Sem considerar o colonialismo e a colonialidade como fraturas profundas na intersubjetividade parece difícil propugnar um futuro razoável para a humanidade e o planeta, pois seguiremos cúmplices da necropolítica e sua pulsão genocida que estrutura o capitalismo global (Mbembe). Deseja-se, assim, sinalizar um novo caminho para o pensamento teológico negro com ferramentas teóricas e conceituas atualizadas.
Science Without Borders: A Descriptive Mobility Study
Authors: Malheiros Igor , De Oliveira Neto João Martins , Duarte Alexandre
Published: March 2020

The international student exchange market has grown significantly over the last decade. In an effort to improve the country's science and technology production, the Brazilian government created the Ciência sem Fronteiras program. The program provides funding for undergraduate and postgraduate students to study abroad. This paper analyzes data from this program, identifying patterns on distributions of students, their states in Brazil, destinations and areas of study. The results show that the long tail distribution appears ordinarily in the data. Furthermore, between pairs of data, the results showed that Quetelet's index was low in most cases, except in a few outliers, such as countries that have hosted a very small number of students.

Real-Time Detection of Planar Regions in Unorganized Point Clouds
Authors: Limberger Frederico , Oliveira Manuel
Published: March 2020

Automatic detection of planar regions in point clouds is an important step for many graphics, image processing, and computer vision applications. While laser scanners and digital photography have allowed us to capture increasingly larger datasets, previous approaches for planar region detection are computationally expensive, precluding their use in real-time applications. We present an O(n log n) technique for plane detection in unorganized point clouds based on an efficient Hough-transform voting scheme. It works by clustering sets of approximately co-planar points and by casting votes for these clusters on a spherical accumulator using a trivariate Gaussian kernel. A comparison with competing techniques shows that our approach is considerably faster and scales significantly better than previous ones, being the first practical solution for deterministic plane detection in large unorganized point clouds.

Kiel 1918
Authors: Rackwitz Martin
Published: March 2020

Der Matrosen- und Arbeiteraufstand in Kiel im November 1918 hat wie kein anderes Ereignis der Kieler Stadtgeschichte den Gang der deutschen, ja sogar europäischen Geschichte verändert. Als am 3. November die ersten Todesopfer einer Demonstration in Kiel zu beklagen sind, beginnt die Revolution. Zwei Tage später wehen rote Fahnen über den Marineschiff en auf der Förde und auf dem Kieler Rathausturm, außerdem erreicht der Aufstand andere Garnisonsstädte im Norden wie Rendsburg, Neumünster und Flensburg. Entlang der Bahnstrecken breiten sich die Umwälzungen rasend schnell aus – Hamburg, Bremen, Ruhrgebiet – bis nach Berlin wird das Land von der revolutionären Bewegung erfasst. Am 7. November wird der republikanische »Freistaat Bayern« ausgerufen, am 9. November in Berlin die Republik. Martin Rackwitz, der in einer umfangreichen Forschungsarbeit zahlreiche neue Quellen zur Novemberrevolution erschlossen hat, lässt die Originalstimmen der Zeit zu Wort kommen und dokumentiert dabei ebenso detailreich wie lebendig die Vorgänge in Kiel in den Novembertagen 1918. Er schildert lebhaft die Vorbildrolle Kiels für die deutsche Revolution 1918 und gibt wichtige Hinweise auf die politischen Entwicklungen in den frühen Jahren der Weimarer Republik. Das Buch macht zudem deutlich, warum ausgerechnet die kriegsmüden Kieler Matrosen und Arbeiter eine landesweite revolutionäre Bewegung entfachten, die das scheinbar so gefestigte Deutsche Kaiserreich innerhalb weniger Tage zum Einsturz brachte und der Weimarer Republik den Weg ebnete.
Sozialgeschichte der Kieler Professorenschaft 1665–1815
Authors: Piotrowski Swantje
Published: March 2020

Wann wandelte sich der Professorentypus vom Universalgelehrten zum modernen Forscher? Dieser Leitfrage widmet sich die vorliegende Studie am Beispiel der Kieler Universität von ihrer Gründung im Jahr 1665 bis zum Jahr 1815. Auf der Grundlage von insgesamt 183 Professorenbiografien verbindet die Autorin sozialgeschichtliche Forschung mit Fragen der Universitätsgeschichte. Ausgehend von der Betrachtung der voruniversitären Bildung, des Studiums und den einzelnen akademischen Stationen analysiert sie erstmals, welchen Einfluss die regionale wie auch soziale Herkunft der Professoren auf den Verlauf der Karrierewege nahm. Die Gesamtdarstellung, die auch die verwandtschaftlichen Verflechtungen der Professoren untereinander und ihr gesellschaftliches Engagement innerhalb der Kieler Stadtgesellschaft in den Blick nimmt, eröffnet damit neue Perspektiven für künftige Forschungsarbeiten, die sich mit dem tiefgreifenden Wandel der Institution Universität im 18. Jahrhundert auseinandersetzen.
Milieus in Lübeck während der Weimarer Republik (1919–1933)
Authors: Freche Julian
Published: March 2020

Die Erforschung der sozialmoralischen Milieus in Deutschland hat sich in den letzten 50 Jahren fast vollständig auf das sozialistische oder das katholische Milieu beschränkt und damit weite Teile der Bevölkerung außer Acht gelassen. Doch gab es neben diesen beiden eindeutig nachgewiesenen Milieus überhaupt weitere? Wie haben sich diese konstituiert und wer gehörte ihnen an? Diese Leitfragen werden in der vorliegenden Untersuchung anhand des Beispiels der Freien und Hansestadt Lübeck während der Weimarer Republik zwischen 1919 und 1933 untersucht. Lübeck gilt als „rote Stadt“, die Existenz eines sozialistischen Milieus muss geradezu vorausgesetzt werden. Doch die Stadt hatte auch eine lange und reichhaltige konservative und liberale Tradition, das "Hanseatentum“ prägte die Stadt wie kaum eine andere und so stellt sich die Frage, ob nicht gerade in Lübeck die Voraussetzungen gegeben waren, um auch ein nationales Milieu herauszubilden. Die vergleichende Untersuchung unterschiedlicher Milieus ermöglicht es gleichzeitig, wichtige Forschungslücken in Bezug auf die Zeitgeschichte Lübecks zu schließen.
Non-Surgical Regional Therapy for Osteoarthritis: An Update and Review of the Literature
Authors: Wilson-Morkeh Harold , Mackworth-Young Charles
Published: March 2020

Osteoarthritis (OA) is the most common joint condition worldwide. It can lead to chronic debilitating symptoms that can be definitively managed with surgical techniques at times. More frequently however, either due to age, extent of disease or patient choice, non-surgical approaches are preferred. They include topical therapies such as thermotherapy, ultrasound, laser treatment, non-steroidal anti-inflammatory drugs (NSAIDs) and capsaicin cream. Injections are another technique often implemented. These consist of intra-articular (IA) corticosteroid or hyaluronan injections, trigger point injections and subcutaneous sodium salicylate. Acupuncture and various types of external support are also widely used. This chapter examines the latest evidence and summarises the role of the various regional treatments available for use in the management of OA.

Published: March 2020

Cerca de 90% dos solos amazônicos são ácidos e de baixa fertilidade, pobres em nitrogênio e fósforo, além de apresentarem toxidez de alumínio, o que limita o seu uso na agricultura regional. Considerando-se o alto custo dos adubos e outros insumos, além das dificuldades de transporte pelos agricultores regionais, os sistemas agrícolas regionais precisam ser redirecionados com vistas a dar à população regional, maior independência em produtos básicos sem causar danos aos ecossistemas. Deste modo, associações micorrízicas do tipo arbuscular, constituem uma alternativa de grande importância para minimizar o uso de fertilizantes, por ajudarem as plantas a explorarem melhor o solo. Os benefícios da simbiose para o hospedeiro resultam de melhorias no estado nutricional da planta, melhor utilização e conservação de nutrientes no sistema, redução de perdas por estresses de natureza biótica ou abiótica. O objetivo deste estudo foi avaliar o efeito do carvão vegetal, adubação química e orgânica do solo na colonização micorrízicas no cupuaçu. O trabalho foi desenvolvido no Km 42 da estrada de Balbina em Presidente Figueiredo no Amazonas. Foram feitas duas coletas de folhas, raízes e solos, uma na época da seca e outra na das chuvas, usando quatro tratamentos com três repetições. Os fungos micorrízicos arbusculares foram avaliados pelo método de clareamento e coloração das raízes. O solo, nos tratamentos com calagem, apresentou maiores teores de Ca e Mg, mas sem reduzir os teores elevados de Al e acidez. A adubação com K e P elevou os teores desses elementos no solo e os de Fe e Zn, que devem estar presentes como traços nos adubos de K e P adicionados.  As colonizações radiculares por fungos micorrízicos arbusculares foram baixas nas duas coletas realizadas, sendo menor na época chuvosa.  A contribuição da simbiose plantas-fungos micorrízicos para a nutrição das plantas foi afetada, devido à baixa ocorrência dos fungos nas raízes. Esporos do gênero Glomus sp foram os que mais ocorreram nos solos, seguidos pelos do gênero Scutellospora sp.

Guest Editorial: The regenerative dentistry: current approaches and future insights
Authors: TATULLO Marco
Published: March 2020

Regenerative medicine typically aims to promote and improve the healing of tissues and organs of the human body, to restore the physiological architecture and the main functions lost.The combination of several scientific fields, including tissue engineering and cell biology, has led to the development of novel regenerative therapies that claim to obtain a better repairing, regenerating and replacing of tissues and organs damaged by chronic and acute diseases, or by severe traumatic injuries. In this landscape, the mesenchymal stem cells (MSCs) have been widely reported to self-regenerate and differentiate towards different tissues, under specific conditions and stimuli. Nowadays, MSCs are routinely used in autologous transplantation: the use of specific molecular effectors and biomimetic scaffolds populated with such MSCs has shown promising results both in vitro and in vivo experiments aimed to achieve a time-effective tissue reconstruction and a functional regeneration of complex organs.

Fatigue Life Assessment and Reliability Analysis of Cope-Hole Details in Steel Bridges
Authors: Liao Ping , Wang Yongbao , Zhang Xiucheng , Zhao Renda , Jia Yi , Zhu Haifeng
Published: March 2020

Cope-hole details are widely applied to steel bridges. However, the safety of steel bridges is influenced by the fatigue performance of welded details. So, cope-hole details with flange and web subjected to axial loads were selected as the research object. Based on the basic theory of linear elastic fracture mechanics and the Finite Element Method, the stress intensity factors of cope-holes details were calculated. The influences of geometry size and crack size of the detail on the stress intensity factors were then investigated. The Paris model of fatigue crack propagation predicted the crack propagation life of cope-hole details. Besides, the fatigue limit-state equation was also established to analyse the effect of random variables (such as initial crack size, critical crack size, crack propagation parameter) on the fatigue reliability index. Finally, the recommended value of the detection period was present. The results show that the stress intensity factor gradually increases with the increase of the cope-hole radius, the weld size, the flange plate thickness, the crack length and the web thickness. However, it gradually decreases with the increase of the ratio of the long and short axle to the crack. The predicted number of fatigue cyclic loading required by the fatigue crack depth propagating from 0.5 mm to 16 mm under nominal stress amplitude of 63 MPa is 122.22 million times. The fatigue reliability index decreases with the fatigue growth parameter, the crack shape ratio and the mean of initial crack size increasing, which is relatively sensitive. However, the variation coefficient of the initial crack size has little effect on it. The detection period of cope-hole details is the service time corresponding to the fatigue accumulated cyclic loading of 198.3 million times.
Vertical Dynamic Loads on Footbridges Generated by People Running
Authors: Pańtak Marek
Published: March 2020

This paper concerns the issue of the dynamic impact of people running on footbridges with particular with attention to various footstrike patterns occurring during the running (i.e. heel strike pattern and forefoot strike pattern). The results of a series of laboratory tests of vertical ground reaction force (VGRF) measurements generated by running people are presented along with the characteristics of the VGRF curves. Based on the results of the tests, a new proposal for a dynamic load model generated by people classified as heel strike runners has been developed, and corrections of the input parameters of two load models proposed by other authors have been performed. Moreover, the VGRF modelling technique using the Gaussian functions is presented along with a set of equations describing the variability of the Gaussian function parameters as a function of the frequency of running. The presented methods of the VGRF modelling allow increasing the accuracy of determining the VGRF values and, consequently, increasing the accuracy of dynamic analyses of footbridges subjected to dynamic loads generated by people running.
Longitudinal Acceleration Models for Horizontal Reverse Curves of Two-Lane Rural Roads
Authors: Echaveguren Tomás , Henríquez Cristian , Jiménez-Ramos Gustavo
Published: March 2020

The operating speed profile models adopt acceleration and deceleration as constant values obtained from kinematic models, assuming that the operating speeds between two consecutive sections are not spatially correlated. Existent research shows that acceleration and deceleration in horizontal reverse curves (HRC) depend on the tangent length and curve radii. In this paper, accelerations/decelerations-geometry models for light cars are proposed. The models are based on the data obtained in-field with a 10 Hz GPS under favourable traffic, weather, and pavement condition to isolate the effect of road geometry over the speed changes. The models were calibrated using the 95th percentile of acceleration probability density function (pdf) obtained section to section in the HRC. It was found that the acceleration and deceleration pdf follow the Burr distribution. Therefore, a Box–Cox transformation is needed to properly calibrate acceleration-geometry models. The models obtained confirmed that accelerations and decelerations depend on the radius of entrance and departure curves of the HRC. The results contribute to better understanding of the acceleration/deceleration patterns of light cars and to enhancing operating speed models in the HRC.

Background

The preoperative controlling nutritional status (CONUT) score and serum carbohydrate antigen 199 (CA199) levels are individually correlated with the prognosis of pancreatic ductal adenocarcinoma (PDAC). The objective of this study aimed to investigate the efficacy of CONUT score and CA199 (CONUT-CA199) combination in predicting the prognosis of PDAC patients undergoing radical surgery.

Methods

We retrospectively analyzed the preoperative CONUT scores and serum CA199 levels of 294 patients with PDAC who underwent radical resection at the Affiliated Hospital of Southwest Medical University between March 2012 and July 2019. Patients were divided into four groups on the basis of their preoperative CONUT scores and serum CA199 levels: CONUTlow/CA199low (1), CONUTlow/CA199high (2), CONUThigh/CA199low (3) and CONUThigh/CA199high (4). The prognostic effects were compared among the groups.

Results

CONUThigh was more frequent in patients with positive peripancreatic infiltration and Clavien–Dindo classification of ≥IIIa (P < 0.001). Kaplan–Meier analysis revealed obvious difference in overall survival (OS) and recurrence-free survival (RFS) among patients with PDAC having CONUT-CA199 scores of 1, 2, 3 and 4 (P < 0.001). Peripancreatic infiltration, lymph node metastasis, pTNM stage, CONUT score, serum CA199 levels and CONUT-CA199 classification were found to be the independent prognostic factors for OS and RFS in multivariate analyses. In time-dependent receiver operating characteristic (ROC) analyses, the area of the CONUT-CA199 score under the ROC curve (AUC) was higher than that of the preoperative CONUT score or serum CA199 levels for the prediction of OS and RFS.

Conclusion

CONUT-CA199 classification may be more effective in predicting the postoperative prognosis of PDAC patients.

Published: March 2020

Background

The nuclear factor I (NFI) is a family of transcription factors consisting of four distinct but closely related genes, NFIA, NFIB, NFIC and NFIX, which are important in the development of various tissues and organs in mammals. Recent study results have shown that NFI family may play a critical role in the progression of various human tumors and have been identified as key tumor suppressors and oncogenes for many cancers. However, the expression levels and distinctive prognostic values of the NFI family remain poorly explored in most cancers.

Materials and Methods

In the present study, the differences in mRNA expression of the NFI family in various cancers were investigated using the Oncomine and TCGA databases, and the mRNA expression, genetic alteration and DNA methylation of the NFI family members in various cancers were examined using cBioPortal for Cancer Genomics. In addition, the prognostic significance of the NFI family was assessed in multiple cancers using the Kaplan–Meier plotter (KM plotter) and SurvExpress databases.

Results

The mRNA expression levels in the NFI family were significantly downregulated in most cancers compared with normal tissues and DNA hypermethylation might downregulate the NFI family expression. Although NFIX expression was not downregulated in kidney, colorectal and prostate cancers. Furthermore, NFIB expression was upregulated in gastric cancer. Further survival analyses based on the KM plotter and SurvExpress databases showed dysregulations of the NFI genes were significantly correlated with survival outcomes in breast, lung, and head and neck cancers. Decreased expression levels of NFIA, NFIB and NFIC were associated with poor overall survival (OS) in head and neck cancer. Low mRNA expression of NFIA and NFIB was significantly associated with OS and first progression in lung adenocarcinoma, but not in lung squamous cell carcinoma. In addition, potential correlations between NFI family members and survival outcomes were also observed in liver, esophageal, kidney and cervical cancer.

Conclusion

The results from the present study indicated certain members of the NFI family could be promising therapeutic targets and novel prognostic biomarkers for human cancers.
ARF family identification in Tamarix chinensis reveals the salt responsive expression of TcARF6 targeted by miR167

Auxin response factors (ARFs) are important transcription factors (TFs) that are differentially expressed in response to various abiotic stresses. The important roles of ARFs and small RNA-ARF pathways in mediating plant growth and stress responses have emerged in several recent studies. However, no studies on the involvement of ARFs in tamarisk trees, which are resistant to salinity, have been conducted. In this study, systematic analysis revealed 12 TcARF genes belonging to five different groups in Tamarix chinensis. The microRNA response elements of miR160, which belongs to group I and miR167, which belongs to group III, were conserved in terms of their location and sequence. Moreover, digital gene expression profiles suggested that a potential miR167 target gene, TcARF6, was rapidly expressed in response to salt stress. Cloning of TcARF6 revealed that TcARF6 could be an activation TF with a glutamine-rich region and expression pattern analysis revealed that the expression of TcARF6 was significantly downregulated specifically in the roots. A significant negative correlation in the expression pattern of tch-miR167/TcARF6 indicated that this module may play a key role in the response to salt stress. Overall, these results provide basic information on the posttranscriptional regulation of TcARF6 for future investigations of the T. chinensis salt-stress response.
Trypophobia as an urbanized emotion: comparative research in ethnic minority regions of China

Published: March 2020

Trypophobia is a strong emotion of disgust evoked by clusters of holes or round objects (e.g., lotus seed pod). It has become increasingly popular and been studied since 2010s, mainly in the West and Japan. Considering this, trypophobia might be a modern emotion, and hence urbanization possibly plays key roles in trypophobia. To address this issue, we compared the degree of trypophobia between urban and less urban people in China. In an experiment, we asked participants about their degree of discomfort from trypophobic images. The results showed that trypophobia occurred in both groups, although the effect size was larger in urban than less urban people. Moreover, post-experimental interviews and post-hoc analyses revealed that older people in less urban area did not experience as much trypophobia. Our findings suggest that trypophobia links to urbanization and age-related properties.

Purpose: Celebrity endorsement has been investigated in prior studies regarding various behavioural and cognitive aspects about consumer purchasing behaviour, it is not clear whether principles findings in the general celebrity literature can be directly applied to the service context. This study examines the effects of different attributes associated with celebrities on purchasing behaviour of life insurance policy in Sri Lanka.

Design: The study used a deductive approach and quantitative research design. Data were collected from 150 life insurance policy holders who representing four insurance companies in Sri Lanka. A self-administrated structured questionnaire was used to collect data. The step-wise multiple regression and regression-based path analysis were employed to test the hypotheses.

Findings: The study finds that celebrity attractiveness, trustworthiness and expertise have significant influence over purchasing behaviour and however the influence is not strong. Further, celebrity trustworthiness has a significant mediating effect on the relationship between celebrity expertise and buying behaviour.  

Originality: Despite the role of celebrity attributes in influencing the buying behaviour of tangible products, limited studies have been conducted specifically on intangible products and also, the literature is not clear whether principle findings in the general celebrity can be directly applied to the intangible product or service context. This study has addressed that empirical gap.
Safety Considerations with Lithium‐Ion Batteries
Authors: Garche Jürgen , Brandt Klaus
Published: March 2020

Safety is an unconditional requirement for acceptance of all batteries in the market. Like all energy‐storage systems, Li‐ion batteries carry the risk of an uncontrolled release of the stored energy. The risks that need to be considered are of chemical, thermal, kinetical, and mechanical nature. Dangers can be the release of toxic gases, explosions, and high‐voltage shocks. The level of risk at the cell level depends on the cell chemistry, especially the choice of cathode, anode, and electrolyte materials. Triggers of safety incidences can be of external nature such as an overcharge, or internal to the cell such as an internal short. Larger batteries must be able to avoid the propagation of a catastrophic failure of one cell to the whole system. Standardized safety testing is required to assess the response of the battery to these triggers, and to assure that this response is within the safe limits defined by the applicable regulations. Users must also contribute to safety by avoiding serious misuse and abuse of batteries. Despite this effort of all concerned, safety events cannot be avoided completely. When these occur, certain rules must be followed to control the risk and minimize the damage that might result from the catastrophic battery failure. Fires that might result from a safety incident must be fought with the correct measures.
High‐Temperature Battery Technologies: Na‐S

Sodium–sulfur (Na‐S) battery technology is one of the most developed types of high‐temperature battery, due to its considerable potential for energy storage and load leveling in power systems. These systems are eligible for use in large‐scale energy storage system applications due to their outstanding energy density, high efficiency of charge/discharge, low materials cost, and long life cycle of up to 15 years. However, several challenges must be overcome to ensure the safe operation of Na‐S batteries – mostly related to the reduction of the high operation temperatures. For this purpose, it is critical to develop new solid electrolytes with high ionic conductivity at room temperature. Taking this into account, ceramic/polymer composites are good candidates to achieve this goal. However, it is important to note an increase of capacity and cyclability is also desirable for Na‐S technology, and one of the strategies used to address this issue is the use of nanostructured carbon to host sulfur or to bind it to a polymer. Since the inception of Na‐S technology in the mid‐1970s, several patents have been developed. Analysis of these patents indicate that, on the one hand they aim to integrate these systems into the electrical grid to compensate the fluctuations of power demand and supply, especially of renewable energies, while on the other hand they show battery component improvements to achieve lower operating temperatures.
