Authors: Zhu Junsong , Sun Baosheng , Cai Jianrong , Xu Yongjian , Lu Feng , Ma Haile
Published: July 2023

Wheat plays an important role in our daily life and industrial production. Several computer vision approaches have been proposed for classifying wheat quality, but there were some methods focusing on the problem of cohesive wheats while image processing. In this paper, we designed a single kernel guide groove to separate the cohesive wheats, which could simplify the algorithm of image processing and improve the accuracy rate of classification. For the method followed while recording the data, the image information must be converted into digital information, and the results are provided using appropriate image processing algorithms. Image preprocessing steps such as binarization, image enhancement, image segmentation, and morphological processing were used to reduce noise. For image segmentation, we proposed the following new segmentation methods: (1) extracting wheat region by converting image to H channel and (2) watershed algorithm based on Euclidean distance transformation. For the classification model, 22 features of 7 different qualities of wheat were inputted in the Back Propagation (BP) neural network and Support Vector Machine (SVM) model, and the overall correct classification rates were determined to be 91% and 97% for SVM and BP neural network, respectively. The BP neural network was more suitable for wheat appearance quality detection.
The Response of Selected Domestic Capital Markets on the Development of COVID-19 Pandemic – a Broader View
Authors: Potrykus Marcin
Published: July 2023

Objective: The study examines how the record of the first, hundredth, thousandth, ten-thousandth, one-hundred-thousandth, and millionth cases of COVID-19 affected investor behaviour in capital markets. It also looks at whether the month in which the first case was recorded in a given market affected the direction and strength of investor reactions. Lastly, it verifies whether the two announcements made by the WHO related to COVID-19 differently affected the behaviour of investors in markets where the first case of the epidemic had already been recorded and in markets where there were not yet officially confirmed cases.Research Design & Methods: Event analysis is used in looking at 77 financial markets.Findings: Investor reactions to emerging information are extreme. The largest sell-off of shares was observed when the first and hundredth cases of the disease were recorded. No statistically significant and negative abnormal rates of return were found for other points studied. The later the first case was recorded in a given market, the greater the scale of discounting in that market. In markets where the first case of infection had already been recorded, the negative reaction of investors was greater than in markets where the first case had not yet been found.Implications / Recommendations: A small number of cases and high uncertainty about COVID-19 have a more substantial negative impact on investors than a high number of cases coupled with a better understanding of the pandemic. WHO announcements further contributed to the occurrence of stronger declines in countries in which people had already become infected by COVID-19.Contribution: The current study is the first of its kind, focusing not only on the first case of COVID-19, but also on other focal points of the evolving pandemic. The other aspects (month, WHO announcements) covered are also analysed from a different, broader view than in other studies.
Barriers to Home Ownership for Young People
Authors: Strączkowski Łukasz , Bartkowiak Piotr
Published: July 2023

Objective: To examine the importance of housing for young people (up to 35 years old) in terms of security and family planning decisions, and to identify barriers to home purchases this cohort sees.Research Design & Methods: The study draws on market-related data sourced from Statistics Poland (GUS) and the national bank of Poland (NBP), and on qualitative and questionnaire-based research conducted by the Poznań University of Economics and Business (Department of Investment and Real Estate).Findings: Our work (which included two studies into the local housing market in Poznań) confirms a marked tendency towards home ownership. It demonstrates that young people consider it essential to have a home of their own for the sense of security it provides and that it may also be a decisive factor in family planning. Furthermore, young adults feel constrained by barriers when purchasing housing. Economic data on housing prices and earnings bear out their belief that prices are rising fast and their earnings are not. Importantly, economic barriers are not the only impediments to home ownership. Psychological and other obstacles also play a role.Implications / Recommendations: The results of our research might be useful in assessing young people’s purchasing power. This in turn might inform the efforts to remove barriers to home ownership or when considering the introduction of support programmes to meet the housing needs of young people.Contribution: The article contributes research on local real estate markets and the place of young people in them. It examines the potential barriers to entering these markets as perceived by individuals up to 35 years. It also describes ways such barriers could be eliminated.
Wykorzystanie netnografii w procesie budowy kwestionariusza ankietowego na podstawie badania minimalizmu konsumentów
Authors: Błoński Krzysztof
Published: July 2023

Objective: To present an overview of the different steps used to create questions for a survey questionnaire, based on the results of a netnographic study. An analysis of the subject literature has also been done.Research Design & Methods: Cues from the literature were used to construct the sample question. The data source was the results of a netnographic study on people’s value systems and minimalism in consumption. The study was carried out on the basis of 13 interviews with people involved to varying degrees in minimalism. Topics covered during the interviews included the question of how to present one’s perception of minimalism (definition of minimalism).Findings: Netnography was used in the first stage of the research process to supplement the small number of surveys conducted among minimalists, which would have resulted in a poor understanding of the phenomenon. Its inclusion enabled direct information to be obtained from the respondents and, together with the literature review, contributed to a more precise formulation of the survey questions.Implications / Recommendations: In the literature, examples of combined use of the results of qualitative and quantitative research at various stages of the research process are increasingly common. The possibilities presented for using the complementarity of quantitative and qualitative research in the form of formulating questions for survey research are one such example.Contribution: While this approach has long been discussed in the literature, it is often shortened or reduced to the necessary minimum (primarily because describing the process of building a research instrument is so complicated). Focusing on this initial stage of building the research instrument provided an opportunity to present the individual steps in more detail.
“Her Language Must Be the Language of Figures”. Medical Statistics of the Russian Empire and the Kingdom of Prussia: A Comparative Perspective
Authors: Mitrofanov Ruslan
Published: July 2023

This article examines the history of the establishment of departmental medical statistics in the Russian Empire and the Kingdom of Prussia in the first half of the nineteenth century. Starting from M. Foucault’s concepts of biopolitics and governmentality, historians have studied the medical and statistical mechanisms for representing “public health” in England, France, and other West European countries in some detail. The case of the Russian Empire remains unexplored in this respect. Researchers have predominantly turned to hygienic statistics and data on mortality and fertility in Russian cities of the late imperial period, while the early period has long remained untouched. Moreover, these data have been analyzed apart from the transnational context of their creation. This article seeks to fill this gap partially. By comparing the introduction of two key medico-statistical indicators in Prussia and Russia (the nomenclature of diseases and the indicator of causes of death by disease), it has been argued that the Russian authorities, in their governing practices, followed mainly the Prussian path. In addition, both countries came to the same statistical model of representing the “public health” of the nation/empire. However, in the case of the Russian Empire, this transition was stretched over many decades and was carried out haphazardly. The article analyzes the main causes of this uneven implementation. In conclusion, it discusses the advantages and disadvantages of each country’s medical and statistical models.
“Tango for Two”: Women’s Interviews in Clinical Reproductive Practice
Authors: Gramatchikova Natalya , Polyakova Irina
Published: July 2023

This article attempts to combine data obtained through interviews by a psychologist of female donors participating in an assisted reproductive technology program and interpret them through narrative analysis and communicative situation analysis. The article describes the structure of an oocyte-donor which has never been done before with reference to Russian-language material. An ethical platform for the study is openness to a new type of scientific knowledge that results from the interpretation of the informants’ answers who try to comprehend their motives to donate. The narrative analysis of 21 transcripts helps determine the roles of the interviewer and the informant at each stage and their contribution to the discussion-testing communicative situation. The interview includes several stages, such as “a window to the past”, at which the autobiographical narrative is recorded as comprehensively as possible; a description of the donor’s current state which focuses on strategies for solving problem situations; the interview ends with a series of thought experiments that allow the psychologist to assess the emotional stability of the potential donor and make a forecast regarding the prospects for long-term cooperation with the reproductive medicine clinic. The paper outlines the cases of participants’ cooperation and mismatches in building a credible and value-consistent autobiographical narrative that includes the donation experience. The authors seek to fit this experience into a broader value context, including a compensatory one related to the urgent problems of potential donors. Women’s answers help specify the concept of donor ‘multi-motivation’. The ambiguity of public opinion regarding donation as a reproductive medicine phenomenon is expressed in the fact that the availability of information for those who are aware of the issue co-exists with donors’ persistent reluctance to display their activity outside the inner circle. Research perspectives include the need to consider the narrative contribution of each participant in the situation of reproduction, i. e. physicians, donors, and recipient parents, and its further use in practice.

Published: July 2023

In this 1.5 year action research pilot study, an interprofessional team of co-researchers studied the use of online intercultural collaboration to integrate music therapy-informed activities into community-based rehabilitation (CBR) with rural families in central India. Over four cycles of action and evaluation, Australian music therapy (MT) co-researchers and Indian CBR co-researchers studied the perceived impact of MT-informed activities in CBR for CBR facilitators and participating families, and the online communication strategies and MT information that were useful. The research team identified that the integration of MT-informed activities into CBR led to a perceived increase in family motivation and engagement in CBR, enhanced connection between CBR facilitators and families, and greater enjoyment and fun for all involved. Researchers also identified some foundational MT techniques that were useful and articulated some practical considerations for online intercultural collaboration. Importantly, the research team clarified the scope of information sharing that was useful in the context of online intercultural collaboration, and the need to prioritise local expertise and resources. Learning from this study may inform other online intercultural collaborations in both music therapy and international/community development.
Comparative analysis of orbital sensors in soybean yield estimation by the random forest algorithm
Authors: Batistella Danielli , Modolo Alcir José , Campos José Ricardo da Rocha , Lima Vanderlei Aparecido de
Published: July 2023

ABSTRACT Remote sensing has proven to be a promising tool allowing crop monitoring over large geographic areas. In addition, when combined with machine learning methods, the algorithms can be used for estimating crop yield. This study sought to estimate soybean yield through the enhanced vegetation index and normalized difference vegetation index. These vegetation indices were obtained using moderate-resolution imaging spectro-radiometer (MODIS) sensors on AQUA and TERRA satellites and multispectral instrument (MSI) sensor on Sentinel-2 satellite. Random forest (RF) algorithm was used to predict soybean yield and the estimation models were compared with the actual plot’s yield. The RF algorithm showed good performance to estimate soybean yield with our models (R2 = 0.60 and RMSE = 0.50 for MSI; R² = 0.63 and RMSE = 0.59 for MODIS). Vegetation indices with imaging dates corresponding to the crop’s maturation had a higher degree of importance in its predictive ability. However, when comparing the actual and predicted soybean production values, differences of 145 kg ha-1 in contrast to 4 kg ha-1 were found for the MODIS and MSI models, respectively. Therefore, the MSI sensor integrated with machine learning algorithms accurately estimated crop yields.

Published: July 2023

ABSTRACT Pisum sativum L. is a multi-purpose crop. The duration of its vegetative and reproductive periods is determined by a combination of temperature and humidity and genotype response to these conditions. To minimize the loss of productivity due to adverse conditions in sensitive periods of the crop, we evaluated the phenological development and production of Pisum sativum L. in different growing seasons. We used a randomized block design, and the experiments were conducted across five growing seasons, with four replications and eight plants per experimental unit. The variables analyzed were as follows: plastochron, number of days to start flowering, full flowering, and beginning of harvest, the accumulated thermal sum to start flowering, full flowering, and beginning of harvest, and the number of pods, pod mass, and total productivity per unit area. The analysis of variance was performed, and the mean values of the data were compared using the Scott-Knott test. Principal component analysis was also performed from Pearson’s correlation matrix of phenological and production variables. In seasons 1, 4, and 5, the plants reached full flowering earlier, and the pod mass was considerably lower, resulting in lower yields. Seasons 2 and 3 were the most productive and showed lower results for plastochron, less thermal sum until full flowering, and a shorter photoperiod, which, combined with low temperatures during the growing season, resulted in a longer cultivation cycle.

Published: July 2023

Resumo Objetivo: O estudo tem como objetivo analisar a relação entre a rentabilidade e a alavancagem conservadora das empresas brasileiras. Originalidade/valor: O estudo contribui para a literatura ao investigar a rentabilidade como um determinante fundamental da alavancagem conservadora das empresas brasileiras, sendo possível entender se essa influência é baseada numa perspectiva de flexibilidade ou de restrição financeira. Design/metodologia/abordagem: A pesquisa se caracteriza como descritiva, documental e quantitativa. A amostra do estudo foi constituída por 271 empresas de capital aberto e 8.823 empresas de capital fechado. Os dados foram coletados na base Refinitiv Eikon para o período entre 2012 e 2019 (oito anos). Para a análise dos dados, o estudo utilizou a regressão logística no software Stata. Resultados: Os resultados indicam que, em média, 5,05% das empresas de capital aberto possuem alavancagem zero, e 29,08% das empresas de capital fechado possuem alavancagem contábil inferior a 5%. No contexto das empresas de capital aberto, quanto mais rentável a empresa, maior a probabilidade de apresentar alavancagem quase zero, corroborando a perspectiva da flexibilidade financeira. Já para as empresas de capital fechado que são menos rentáveis, há maior probabilidade de apresentarem alavancagem zero, o que coaduna com a perspectiva da restrição financeira.

Published: July 2023

Resumo Objetivo: Compreender os mecanismos de proteção de direitos de propriedade utilizados no sistema agroindustrial (SAG) do leite no Paraná, Brasil, e na antiga região de Midi-Pyrénées, França. Originalidade/valor: A partir de uma perspectiva complementar da Economia dos Custos de Transação e da Economia dos Custos de Mensuração, a proposição é que o uso de mecanismos de garantia de direitos de propriedade, de forma complementar, por meio de salvaguardas, parâmetros, mensuração, acordos ou litígios, contribui para a transação de produtos diferenciados, a proteção desses direitos e melhorias no sistema. Design/metodologia/abordagem: Trata-se de pesquisa qualitativa do tipo descritiva contemplando 25 entrevistas semiestruturadas com produtores, processadores e agentes-chave do SAG do leite no Brasil, no estado do Paraná, e na França, na antiga região de Midi-Pyrénées, nos anos de 2016 e 2017. A análise de conteúdo qualitativa foi realizada com o auxílio do software Nvivo Pro. Resultados: Identificou-se que, na França e nas regiões centro-oriental e oeste do Paraná, o uso de mecanismos de proteção de direito de propriedade de maneira complementar (salvaguardas, parâmetros, mensuração, acordos ou litígios) permite a transação de leite com qualidade superior e reinvestimentos na produção por parte dos agentes, contribuindo para melhorias no sistema. Na região norte do Paraná, o uso limitado de mecanismos de proteção dos direitos (acordos verbais, mensuração e compartilhamento de informação não confiável e ausência de proteção ex post) permite a transação do leite com qualidade mínima e restringe reinvestimentos na produção, limitando as melhorias no sistema.
COMMAS IN TEXTS OF STUDENTS FROM AGE 11 TO 15-YEARS-OLD: A LONGITUDINAL STUDY
Authors: TENANI Luciani , CARVALHO Tainan
Published: July 2023

ABSTRACT In this article, we investigate the presence and the absence of commas in a longitudinal sample of texts of the genre report written by 11 to 15 years-old students from a school in the countryside of São Paulo State. Our hypothesis is that the comma is used when syntactic boundaries match the prosodic ones. The prosodic constituents are formed from syntactic and phonological information, according to principles defined in the Prosodic Phonology theoretical approach. The characterization of the conventional commas and the non-conventional absences of commas was made from the identification of syntactic boundaries in which they should or could be placed, taking as reference a Brazilian Portuguese grammar. The results were that the conventional comma increases during the years of schooling, as expected. However, the presence and absence of comma rates changed depending on the type of syntactic structure and on the occurrence of intonational phrase boundaries. Comma occurred predominantly in positions where intonation phrase boundaries match major syntactic boundaries, as a sentence boundary. In turn, the comma systematically does not occur in positions where the syntactic and prosodic boundaries do not match.
FRAMED STATEMENTS OF “VAGRANT” BODIES: READING OF AN ARCHIVE OF POLICE REPRESSION ON TRAVESTI PROSTITUTION
Authors: PALMA Daniela
Published: July 2023

ABSTRACT This article examines a police file on repression of travesti prostitution in the 1970s in the city of São Paulo. The aim is to use police documents to analyze the strategy of having framing bodies to manufacture criminals, in the frame of the penal discourse on the vagrancy misdemeanor. The research corpus is 316 affidavits issued by the Civil Police of São Paulo, criminological texts, laws, and a police manual, gathered through documentary research. A multidisciplinary reference base (linguistic, historical, legal, and philosophical) is the basis for the integrated reading of the corpus materials. The analyses focus on the construction of the penal argument, the instances of enunciation, and the observation of formal elements that point to the criminalization of cross-dressing prostitutes by mobilizing a language apparatus to physically and morally describe their bodies. The discursive strategies are interpreted in this study as technologies of a pastoral power that acts on the circulation of bodies in urban spaces in the context in question, following Michel Foucault’s understanding.

Published: July 2023

ABSTRACT In this paper, the school material culture of Lyceu Maranhense is analyzed, aiming to understand the dynamics of teaching and the treatment given to school objects according to the discourses, considering the imposed school and teaching model. It is based on the theoretical-methodological assumptions of cultural history, to capture tension as a form, device, structure and frequency of instituted norms/recurrent practices, in addition to the adaptations of subjects that oppose imposition strategies and appropriation tactics of ergological equipment. It is concluded that the pedagogical practice, in this institution, is decisively influenced by European centers and that the material school culture is a participant in all these contexts.
Cine y Educación: una historia de los discursos a favor del cinematógrafo en la escuela
Authors: Jara Camilo Bácares
Published: July 2023

RESUMEN El cine desde su invención fue rápidamente capitalizado para educar. Pese a que también se le tachó de perjudicial nunca ha dejado de usarse en la escuela. Por supuesto, esta dinámica no fue natural. Respondió a enfoques, ideas e intuiciones que lo leyeron como positivo, educativo y afín a objetivos moralistas, estéticos y cognitivos. Mediante una perspectiva histórica y una revisión documental, en este texto se plantean siete tramas educativas, tecnológicas, culturales y económicas que explican la continuidad de esta relación, es decir, las razones, saberes, fenómenos y representaciones que a lo largo de la historia han determinado la incorporación del cinematógrafo a la escolaridad.

Abstract Introduction The intervention of respiratory physio-therapy in neonatal units is in continuous development, having its own care characteristics related to the weight and gestational age of the newborn, respecting the immaturity of the organs and systems and the diseases of this patient. Through techniques, the objective is to optimize the respiratory function, assisting in the clearance of secretions, and the restoration of lung volumes. Objective To verify if the respiratory physiotherapy technique of selective insufflation alters the cerebral blood flow in premature infants under 34 weeks of gestational age. Methods This is an uncontrolled clinical trial, conducted in a Neonatal Intensive Care Unit of a level III hospital, between January 2019 and March 2020, with participation of premature newborns under 34 weeks of gestational age. All were submitted to transfontanellar Doppler ultrasonography to assess cerebral blood flow measurements, mainly the resistance index, before and after the application of the selective insufflation respiratory physiotherapy technique. Results Sixty-two newborns were included, with a mean gestational age of 29.3 ± 2.2 weeks and birth weight of 1,259 ± 388 grams. The resistance index did not change significantly (RI before: 0.55 ± 0.07; after: 0.54 ± 0.07; p = 0.06) before and after the intervention and no studied variables such as, gender, gestational age, weight, Apgar score or SNAPPE II score had an influence on cerebral blood flow measurements. Conclusion The selective insufflation technique did not alter cerebral blood flow in premature newborn infants under 34 weeks gestational age.

Published: July 2023

In recent decades, health apps have become widespread. Patients with musculoskeletal diseases use this software to self-manage their symptoms and continue their diet. The purpose of this study is to scope a review of articles related to the apps developed for musculoskeletal patients to identify and synthesize relevant knowledge. This research was based on the population, intervention, comparison, and outcome (PICO) model. A preferred reporting items for systematic reviews and meta-analyses (PRISMA) flow diagram was used to report the literature search and review process. The Cochrane Risk of Bias tool was used to evaluate bias in randomized clinical trials (RCTs). A database search was conducted to find RCTs published from January 1, 2012, to November 29, 2022, across databases. For each article relevant to an app for patients with musculoskeletal disease, we qualitatively evaluated its information on country, target health problem, outcomes, comparisons, study design, and variables assessed to determine the efficacy of the app. Among the reviewed articles, 34 were included in this review. In these articles, most apps investigated focused on knee osteoarthritis (32.35%). The apps addressed a variety of variables, but self-management in pain control (38.23%) and exercise (17.64%) were the top two subjects. Most of the apps were developed in the US (23.52%). The global trend toward mHealth apps for self-management of diseases is increasing. It seems that existing mobile apps not only are insufficient but also do not fully cover the growing needs of patients with musculoskeletal disorders. Continued research and development in this area are critical to meet the needs of a growing population living with the long-term effects of musculoskeletal diseases.
Prediction of concrete carbonation based on the inverse Gaussian process and Bayesian method
Authors: Chen Long , Huang Tianli , Chen Hua-peng
Published: July 2023

Concrete carbonation is one of the major factors causing the deterioration of reinforced concrete structures. Therefore, accurately predicting the carbonation depth is of great significance in safety assessments of structures. The aim of this study was to develop a method to predict carbonation behaviour by incorporating multi-source information using the Bayesian method. First, the inverse Gaussian process was used to model the evolution of carbonation depth; this captured the temporal variability and the monotonicity of the deterioration phenomenon very well. Then, a proper prior for the model was determined using knowledge from the existing empirical carbonation model. To fuse the accelerated carbonation data and field inspection data, Bayesian inference was performed to update the posterior distributions of the model parameters by the Gibbs sampling technique. A practical example case was used to illustrate the validity and accuracy of the proposed approach.

Published: July 2023

The CuSn10 alloy (bronze with 10% tin) has remarkable mechanical properties, including good elongation and medium hardness. Additive manufacturing of this powder compound is developing at a fast rate. In this study, optimization of the process parameters of the selective laser melting method was carried out to manufacture CuSn10 compounds. In addition, a numerical model for the simulation of the melt pool behavior was created by utilizing the Ansys 2021 R1 software, and a comparison was carried out between predicted numerical data and the obtained experimental results. The formation conditions of various melt traces were modeled, measured and validated for this aim. In the experimental stage, a constant laser power of 95 W was used, and the effect of the variation of the scanning speed was studied between 10 and 1500 mm/s. The results showed that the variation of the scanning speed is not enough, and optimization must be carried out by including other process parameters. This indicates that by adjusting the process parameters to have a 365 W power, the liquid phase can be achieved in the production process.

Authors: Dinarelli Simone , Sikora Andrzej , Sorbo Angela , Rossi Marco , Passeri Daniele
Published: July 2023

The design, optimization and realization of innovative nanocomposite materials for advanced applications in a broad range of fields, from energy, automotives and photonics to biology and nanomedicine, require the capability to characterize their physical properties (e.g. mechanical, electric and magnetic) from a multiscale perspective, in particular not only at the macroscopic scale but also at the nanometer one. In particular, methods are needed to characterize mechanical properties at a nanometer lateral resolution, in order to understand the contribution of the nanosized features of the materials and related phenomena. Atomic force microscopy (AFM) has evolved from a tool for the morphological analysis of the sample surface to an integrated platform for the physicochemical characterization of samples. Current AFM systems host several advanced techniques for the mechanical characterization of materials at a high speed and a high lateral resolution in a broad range of mechanical moduli – for example, from stiff samples (e.g. coatings and crystals) to soft materials (e.g. polymers and biological samples) – in different environments (e.g. air, vacuum and liquid) and conditions (controlled humidity and controlled temperature). Here, a short review of AFM-based methods for the nanomechanical characterization of materials, in particular, force spectroscopy, is reported with the emphasis on materials that can be analyzed.
The Scientist Bishop: Richard Watson, F.R.S. (1737–1816)
Authors: Morgan-Guy John
Published: July 2023

Although as a professor of Divinity, diocesan bishop and political controversialist Richard Watson has attracted the attention of historians in those disciplines, his pioneering work as a scientist and agricultural reformer, especially in relation to arboriculture, has been largely
overlooked. This paper seeks to redress the balance by focusing on his enduring interest in the emerging fields of applied science and demonstrate his important contributions to the cultivation of trees, larches in particular, as a commercial enterprise.
'The Real Question of Freedom': The State, the Church and the Individual, c.1860–1920
Authors: Ingram Robert G , Fitzwater Adeline
Published: July 2023

This essay explores the relationship between the individual, the state and the church. In particular, it considers he ways that a particularly influential group of early twentieth-century state-critics – the English pluralist – grappled with the tension between state authority
and individual liberty through a careful engagement with the thought of John Henry Newman. But while English pluralists like J. N. Figgis and Harold Laski admired Newman's critiques of ultramontanism, they could not accept some of Newman's premises, particularly those regarding the conscience,
which underlay his rejection of ultramontanism. English pluralism, this essay suggests, was beset by a kind of conceptual confusion which its proponents recognized but could not – or would not – resolve.
The Long Methodist Union: A Case Study of Methodism in the Whitby Area of Yorkshire With a Focus on Methodist Union in 1932 and its Aftermath
Authors: Metcalfe Christopher
Published: July 2023

In 1932 the three Methodist denominations, the Wesleyan Methodists, the Primitive Methodists and the United Methodist Church were united to form a single Methodist Church. The impetus for union had come mainly from the leadership of the denominations who desired to create a more efficient
and effective structure for evangelism in an increasingly secular society. However, it was left to the circuits and societies at the local level to determine how this vision was to be put into practice. This article discusses the local situational and the cultural factors that influenced the
process of union in Whitby and, in particular, those that inhibited the desired outcomes of the leadership. The article argues that although the denominations legally became one Methodist Church in 1932, Methodist Union was a long process and there were many factors at the local level that
determined the pace and the shape of union.
The Briouzes, Clares and the Dynasty of Deheubarth, 1180s–C.1230
Authors: Brodie Hugh
Published: July 2023

Limitations in documentary primary sources work to downplay political and military cooperation between Welsh and Marcher lords. When all the clues are considered, substantial cooperation can be detected between segments of the Deheubarth dynasty and segments of the Briouze family between
the mid-1180s and the early 1230s, and also, latterly, with the Clares. Considered alongside the well-known collaboration between the Marshal earls of Pembroke and junior members of the Deheubarth dynasty, the pattern of behaviour is strong. It would be inappropriate to speak of 'alliances':
these were, instead, hard–nosed political understandings that lasted as long as they were of mutual benefit. Comparison with political dynamics in Ireland is revealing.
Duty and Personal Advantage Combined: The War Savings Movement in Pembrokeshire During the First World War
Authors: Hancock Simon
Published: July 2023

The waging of war in the twentieth century required a nation state to mobilise and employ its entire population into productive effort beyond those with direct involvement in the various branches of the armed forces. The First World War witnessed an unprecedented expansion in British
munitions and armaments manufacture, transport and the effort to supply an army of five million while maintaining acceptable living standards on the home front. These vital, interconnected objectives required the belligerents to muster every economic and financial resource at their disposal,
and expenditure on such an unprecedented scale would have budgetary consequences long after the Armistice in November 1918. Domestic borrowing facilitated the thirteen-fold increase in government, but exactly how communities responded to national savings campaigns, and how genuinely popular
savings movements developed in rural counties like Pembrokeshire, have not attracted extensive scholarly research. The focus of this article is to examine how the county of Pembrokeshire reacted to war savings propaganda and what influenced citizens in lending to the state.
1936 Surrealism and Three Dimensions: Early: Context for the Art of Ceri Richards
Authors: DafyddW
Published: July 2023

The Modernist painter Ceri Richards had his first real exposure to European modernism in the 1920s and 1930s. The visibility of post-impressionist art and the accessibility of turn-of-the-century art theory was accelerated for him during his first years as a student in London and, despite
still being at a critical cultural distance from the modern movement in Paris, the assimilation of what he understood of Matisse and his lifelong-obsession with Picasso was rapid. This article isolates the significant exposure that came next for Richards as an emerging modernist, in and around
1936, and specifically to that year's International Surrealist Exhibition held in London.
'The Living Dead of the Mining Industry': Deindustrialisation, Sheltered Workplaces and the Re-employment of Disabled Miners in Post-war Wales
Authors: Thompson Steven
Published: July 2023

This article considers the considerable efforts made to provide disabled ex-miners in south Wales with alternative sources of employment in the post-1945 period. It focuses on Grenfell and Remploy factories and voluntary efforts at the Maes-yr-Haf Educational Settlement at Trealaw in
the Rhondda Valley, and assesses the extent to which these initiatives succeeded in the provision of employment to such men and helped reduce the levels of disabled unemployment in post-war Wales. These efforts are placed in the contexts of the post-war managed economy, attempts to diversify
the south Wales economy, the creation of the welfare state and the particular industrial relations of the coal industry.

Aplicación de raíces cruzadas polinomiales al intercambio de energía radiante entre dos geometrías triangulares
Authors: Camaraza-Medina Yanan
Published: July 2023

El factor de visión entre superficies es un elemento esencial en la transferencia de calor por radiación. En la actualidad, la literatura técnica no disponible de un método analítico para calcular los factores de visión en el intercambio de energía radiante entre superficies triangulares. Desarrollar un modelo analítico para geometrías triangulares requiere la suma de integrales múltiples, debido al cambio en los contornos de integración de las superficies, lo cual complejiza obtener la solución de diversas configuraciones. En este trabajo se pretende el desarrollo analítico de una expresión del factor de visión para el intercambio de energía radiante entre 32 configuraciones geométricas triangulares con bordes comunes y ángulo teta incluido. Para establecer comparaciones, fueron calculados 42 ejemplos con diversas configuraciones de forma para cada geometría usando la soluciona analítica (SA), la solución numérica obtenida con la regla múltiple de Simpson 1/3 con cinco intervalos (RMS) y los factores de visión computados mediante las raíz cruzada de Bretzhtsov (RCB). A partir de ocho geometrías básicas, mediante la regla de sumatorias es obtenido el factor de visión para otras 24 geometrías triangulares. En todos los casos evaluados, la RCB mostró los mejores ajustes. La naturaleza práctica de la contribución y los valores razonables de ajuste obtenidos, establecen a la propuesta como una herramienta adecuada para su uso en la ingeniería térmica.
