Authors: Pinchuk Lyudmila Grigor'yevna , Egorova Irina Nikolaevna , Maltseva Elena Mikhailovna
Published: May 2023

The purpose of the work is to study the pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.) of the legume family (Fabaceae) herb amino acid composition and forage value, introduced in the Kuzbass. Eighteen proteinogenic amino acids were identified in the raw materials of the third and fourth years of introduction. Eight of them are irreplaceable and ten of them are replaceable. The amino acids total content differed significantly by years and amounted to 6.266±0.89% in the third year and 12.541±0.51% in the fourth year. The content of tryptophan, arginine, leucine+isoleucine, valine, histidine, aspartic acid, and serine varied more strongly from year to year. The content of proline, tyrosine, and methionine varied less. Amino acids with polar negatively charged radicals (acidic) prevail. Their part of the total amino acid content averages 36.20%. Amino acid’s part with non-polar radicals (neutral) is slightly less – 31.80%. The smallest specific weight had amino acids with polar positively charged radicals (basic) 11.85%. Aspartic and glutamic acids, leucine+isoleucine, arginine, serine, proline were characterized by a larger part of the total amino acids.

The crude fat, protein, ash, Barnstein protein, nitrogen-free extractive substances and phosphorus content reached the highest values in the third and fourth years. The crude fiber and calcium amount decreased with increasing plant age. Metabolic energy and energy feed units for raw nutrients for cattle averaged 8.98 MJ/kg and 0.90, respectively. The highest values were reached in the third and fourth years of cultivation. Thus, pale-flowered licorice grass is a promising plant as a fodder crop and for the preparation of feed additives.

Published: May 2023

The paper considers the antioxidant properties of water and alcohol extractions of fermented and unfermented fireweed of the narrow-leaved fireweed family (Chamerion Angustifolium Onagraceae), St.), bitter wormwood (Artemisia absintium L.), red clover (Trifolium pratense). The effect of the fermentation process, solvent, and extraction time on antioxidant activity (AOA) was studied. A comparative assessment of the antioxidant properties of medicinal plants of the Perm region was carried out. Using the potentiometric method, it was found that the AOA values of water extracts of fireweed angustifolia increase with the time of extraction. Fireweed weakly fermented (finely ground) and fermented (finely ground) have the highest AOA values during extraction within 24 hours. Shoots of young fireweed angustifolia have very low AOA values compared to unfermented and fermented samples. The AOA of aqueous extracts of medicinal plants increases with the time of their extraction. Oregano has the highest AOA value – 2.78×10-2 mol-equiv, and red clover has the lowest value – 0.37×10-2 mol-equiv. The highest value of AOA among mixtures of medicinal plants has a mixture of oregano with fermented fireweed (finely ground) – 2.52×10-2 mol-equiv. It has been established that extracts prepared from 40% ethanol solution for fireweed angustifolia and 20 and 40% for oregano have the highest AOA values. The AOA values for the alcohol extract of oregano increase depending on the time of its extraction.

Pulicaria salviifolia and P. gnaphalodes belong to one of the richest terpenoid plants of the genus Pulicaria (family Asteraceae). The genus includes 63 species, 16 species grow in Uzbekistan. In folk medicine, plants are actively used to treat various diseases, and have long been used as a natural remedy for mosquitoes, flies and fleas. Secondary plant metabolites are of great practical interest as a natural raw material for the creation of biopesticides.

The aim of this work was to study the chemical composition of the volatile components of gasoline fractions of Pulicaria salviifolia and P. gnaphalodes plants and to study their insecticidal activity against the number of insect pests.

For the first time, the composition of volatiles in the aerial parts of Pulicaria salviifolia and P. gnaphalodes was studied by GC/MS. It was revealed that the predominant components of P. salviifolia are β-terpineol (10.44%), isospatulenol (8.00%), iceol (6.79%), sabinene hydrate (5.72%), l-caryophyllene (4.24%), terpinene-4-ol (4.07%), d-cadinene (3.65%), α-amorphous (2.30%). Calaminene (12.44%), 2-phenylpyrazol-3-amine (8.61%), 1,3,5-cycloheptatriene (7.71%), 1,8-cineole (6.06%), 2-heptene dominate among the volatile substances of P. gnaphalodes-1-ol, 2-methyl-6-(4-methylphenyl)-, (E)- (6.04%), 1-bromohomoadamantane (5.73%), 7-acetyl-2-hydroxy-2-methyl-5-isopropylbicyclo[4.3.0]nonane (4.83%). Gasoline fractions of Pulicaria salviifolia and P. gnaphalodes were tested for insecticidal activity against apple aphid (Aphis pomi), peach aphid (Myzus persicae Sulzer) and cowpea weevils (Callosobruchus maculatus). An insecticidal activity was studied in laboratory conditions. A comparative study of the biological activity of the fractions showed that the biological efficiency of the P. gnaphalodes extract fraction after 24 hours at 0.5% concentration was higher: in relation to Aphis pomi 96.6%, Myzus persicae Sulzer – 76.0% and Callosobruchus maculatus – 90.0%, for the fraction of Pulicaria salviifolia extract in a 0.5% dose, these indicators were 60.2%, 72.0% and 86.6%, respectively.

Iparpolitikai stratégiák Európában - Németország
Authors: Szabó Dorottya
Published: May 2023

Németország iparpolitikai stratégiájának feltérképezéséhez elsődleges forrásként a német Gazdasági és Klímaügyi Minisztérium publikációira, illetve nyilvános kommunikációjára támaszkodtunk. Ezek közül is kiemelendő a minisztérium által 2019 végén, „Iparpolitikai Stratégia 2030” címen kiadott jelentés. Bár 2019 végén még Peter Altmaier vezette a minisztériumot, Robert Habeck, jelenlegi gazdaság és klímaügyi miniszter kommunikációja nagyrészt összhangban van az említett stratégiával, így azt fontos kiindulópontnak tekintjük. Az ukrán háború következtében kialakuló energiaválság természetesen előtérbe helyezett olyan problémákat – elsősorban az energetikai átállás kérdését –, amelyek Habeck kommunikációjában erősebben jelennek meg, mint amekkora figyelmet kaptak a tizedforduló kapujában felvázolt stratégiában, azonban az akkor a 2020-as évekre megálmodott német iparpolitika alapjai továbbra is relevánsak.

Making community-based learning and teaching happen: findings from an institutional study
Authors: Shah Rehan , Preston Anne , Dimova Elena
Published: May 2023

Community-based learning and teaching in higher education, and other versions of it, such as service learning, are now part of many curricula worldwide. In the UK, there is a growing community of practitioners interested in student learning in partnership with local communities. With this expansion, however, there is little institution-based research which ‘looks within’, in terms of shared understanding and supporting this type of experiential learning ‘at scale’. Within the context of increasing interdisciplinary interest by those developing curricula beyond the traditional home of engaged research and teaching (for example, in urban studies and sociology), we undertook an institution-wide study to discover the shared understandings of community-based learning and teaching, including the potential barriers to, and opportunities for, community-based learning and teaching approaches. In this article, we share insights from a series of 20 university stakeholder interviews, which involved academic teachers, engagement professionals and those supporting learning and teaching. We used a ‘students-as-partners’ approach, where students interested in community-based learning took the leading role in the qualitative study. Our findings reveal the values and expectations, formal learning benefits and infrastructural considerations to implement this type of learning as part of future-facing curricula. We also provide recommendations for universities seeking to develop their own approaches towards facilitating community-based learning and teaching.
Mapping Doctoral Research in Library and Information Science at Panjab University Chandigarh
Authors: Verma Reshma Rana , Kumar Shiv
Published: May 2023

The paper examines doctoral research in the library & information science discipline at Panjab University, Chandigarh, based on student’s perceptions and expectations by posing several research questions. This study aimed to gain insight into research scholar’s perspectives on earning a Ph.D. Based on primary data from 48 respondents through a structured questionnaire in April 2018, the study tabulated, analysed and interpreted information to draw inferences. As the study is limited to research scholars at the DLIS at Panjab University, the universe of the study is relatively narrow. The study’s findings reveal that most respondents had a personal decision to get admitted to the Ph.D. programme. However, there were cases where better job prospects, promotion in career, some practical problems, and the advice of a friend/senior/teacher motivated them to join doctoral research. The Panjab University was the first and last choice for the majority of respondents for doing a Ph.D. Two-thirds of respondents stated that quality of doctoral research accomplished in the DLIS PU is good and applied, and three-fifthsbelieved that the research quality has improved with time. Only one-fifth of respondentsfound quality of physical Infrastructure for doctoral research work in the Department is of the best quality. Several respondents feel that doctoral research at Panjab University and India, in general, still depends on research models applied in Western countries, especially in the UK and USA. However, a group of respondents believed it is either struggling to have its own identity or is a blend of Western and Oriental modes. Researchers will be encouraged to choose regionally relevant and application-oriented topics.
Analysis of the Educational Application Users Satisfaction Levels by Using the Integrated Entropy Weight VIKOR Method
Authors: Dina Nasa Zata , Juniarta Nyoman
Published: May 2023

A product review is an essential metric to understand the acceptability level of users. This rating process is often implemented to measure the quality and excellence of a product. It also helps the decision-making processes of potential users regarding the implementation of applications, due to the observation of many options. Furthermore, a product review enables the comparison of applications before imminent subscription. In this case, potential users often analyze various rating levels and perform selection within the Google Play Store based on the experiences of other subscribers. The review is also found to benefit students and software developers, concerning the strengths and weaknesses of the applications. For developers, subsequent modifications of products are mostly supported by this rating process during development. From this context, users and developers need to incorporate Multi-Criteria Decision-Making (MCDM) models, to understand the best and worst applications. Therefore, this study aims to assess the important criteria expected by users of seven educational service applications, by using the integrated Entropy Weight-VIKOR method. In this report, the service applications were selected based on the highest number of users in the Google Play Store.All criterion’s mass was also calculated through the entropy weight method. To rank the application through eight selected criteria, the VIKOR method was subsequently used. The results showed that the best educational service application qualities were Khan Academy and Udemy, with Socratic being the lowest. Some criteria such as download (Cr 1 ), video (Cr 2 ), cost (Cr 3 ), and teacher (Cr 8 ) were also suggested for improvement. From these results, thev-value did not affect the rankings of Khan Academy, Udemy, or Socratic, although it influenced the positions of other applications. This indicated that Khan Academy and Udemy had excellent customer satisfaction levels, regarding functionality and few specific complaints. However, Socratic had high complaints from individuals and low users satisfaction. Based on these results, a comparative analysis was carried out with the baseline study, for analytical validation. In this case, better outputs were observed for the present study than the baseline analysis, due to having three stable ranking positions.

Knowing barriers to information seeking is imperative as it regulates the degree to which individuals can access different sources. The aim of this study is to examine the barriers faced while seeking cultural heritage information. A survey-based questionnaire was used to collect data from the state of Manipur, India. The study employs stratified random sampling techniques and a sample of 400 respondents participated in this study. A structured questionnaire was used to collect data for the study. Before analyzing the data validity and reliability test was carried out. SPSS version 20 was used for data analysis. An independent samples t-test and analysis of variance (ANOVA) was administered to determine significant difference between demographic variables and study variables. The mean analysis revealed, “information is not readily available” with a mean score=3.59 is the most vital barriers. 12 studied variables were subjected to factor analysis and generated three factors, i.e. independent, administrative and management barriers. Statistical analysis revealed that gender difference plays a significant role in dissimilarity in seeking CHI with an individual barrier; with p=0.050, female respondents have a higher difference with a mean score = 3.4289.

Authors: Shimray Somipam R
Published: May 2023

The purpose of this study is to investigate researchers’ attitudes, perceptions, and barriers toward scholarly publication. The current research can be a foundation for conversations on removing obstacles to scholarly publication. A total of 284 researchers participated in the present study. This quantitative analysis is based on a structured questionnaire through convenient sampling. For gathering data, a self-administered questionnaire was developed. The author used descriptive statistics to examine the data. Half (50 %) of the respondents had 1-2 years of research experience. Most of the participants (71.8 %) had participated in a session on research methods, and nearly half (48.9 %) had attended a session on article writing. Additionally, close to one-third (29.2 %) had written 1-2 articles, and more than half (59.5 %) had published research articles in a journal. The scholarly publication contributes to the academic growth of the institution, research enhances professional development and lack of research skills was the most prominent item considering attitudes, perceptions and barriers towards scholarly publication respectively. Across the tested analysis, gender has no significant difference, while age has a substantial difference in participating in conducting research. Gender has no significant difference, while age significantly correlates with article publication. Experience impact in conducting meaningful research, whereas attending research methodology training correlates with publishing articles and attending an article-writing workshop correlates with published articles. Incessant and collective consideration is imperative to overcome barriers to publishing scholarly articles. Moreover, training in research methodology, article writing, mentorship, facilities and funding are prerequisites for conducting research.
MULTIDISCIPLINARY COLLABORATION IN NURSING CARE IN THE FIELD OF ORAL HEALTH STRENGTHENING
Authors:   Community Health Center Ajdovščina, Marc Damjana
Published: May 2023

Oral health affects the health of the whole body, so it is absolutely necessary that the strengthening of oral health takes place in parallel with health education in patronage care, education of pregnant women in women's dispensaries, children and parents in children's and school dispensaries, in reference clinics and dispensaries for diabetes and lung diseases. The task of the nurse at the primary level is to treat patients holistically. However, since formal education only touches on strengthening oral health, it would be necessary to formulate recommendations for strengthening oral health in all areas of nursing care at the primary level. The oral health group at the National Institute of Public Health plays a major role in the development of these guidelines. The article contains a short survey and explanation of the knowledge of the field of oral health and the implementation of strengthening the oral health of nursing providers at the primary level.

Published: May 2023

Introduction: Mentorship of nursing students in the clinical environment is important for their professional development. With mentorship programs they can upgrade theoretical knowledge acquired in faculty into practice. Purpose of this study is to research the view of senior registered nurses on mentorship programs of nursing students in the clinical environment. Methods: The study took place in the October of 2022 in one of the university medical centers in Slovenia. To gather the data we used quantitative method of research with questionnaires where we enrolled 36 registered nurses. Data was analyzed with Microsoft Excel and SPSS (Inc., Chicago, IL). To summarize data set we used descriptive statistics and the Mann Whitney U test to analyze the hypothesis. Results: We found that enrolled registered nurses had no previous pedagogic training for mentorship (PV=1,88; SO=0,854), but they would like to get more educated in this field (PV=3,30; SD= 1,283), mostly because they enjoy being a mentor to students (PV=3,77; SO 1,098). There is a correlation between age of registered nurse and the will to participate in further pedagogic training of mentorship (Z2,571; p=0,010). Discussion: Mentorship has an important role in education and professional development of nursing students, therefore it is crucial that they are supervised by experienced and adequately educated senior registered nurses
EPIDEMIOLOGICAL SURVEILLANCE OF SURGICAL WOUND INFECTIONS AS A LEADING INDICATOR OF THE QUALITY OF POST-SURGICAL CARE FOR CHILDREN
Authors:   University Medical Centre Ljubljana, Sijamhodžič Aida , Žvikart Alenka ,   University Medical Centre Ljubljana
Published: May 2023

Introduction: The European Centre for Disease Prevention and Control (ECDC) ranks surgical wound infection among the most common hospital infections, which, as a result, can prolong the hospitalization time, requires additional surgical interventions, treatments and intensive therapy, or even increases mortality. Implementation of epidemiological monitoring reduces the incidence rate of surgical wound infections, and monitoring the incidence rate enables assessment of the quality of medical care. After increasing importance of verification levels of quality of medical care, the University Clinical Centre Department of Paediatric Surgery decided for the project of systematic prospective monitoring of surgical wound infections in children. Methods: A quantitative research method was used with a prospective and retrospective data analysis for certain interventions. The research project was divided into several phases. The research sample included children at the Department of Paediatric Surgery for planned and emergency surgical interventions. The children were monitored for 30 days after the intervention (in the case of an implant for 90 days). The goal of the research was to establish clinical practice of monitoring surgical wound infections in children, and the introduction of appropriate preventive measures for reducing the incidence of surgical wound infections. Results: In two months, 74 surgical interventions were analysed. Analyse showed a 4.05 % incidence of surgical wound infection. In all cases it was superficial incisional surgical wound infection. Discussion: Prevention of surgical wound infections is becoming an important part of the national health strategies in many developed countries. Expert knowledge teaches us, that a significant part of healthcare-related infections can be prevented, often by following simple rules. With the project of prospective monitoring of surgical wound infection, we first of all want to define the incidence of surgical wound infection after various surgical interventions in children, to recognize risk factors for the occurrence of surgical wound infection and introduce appropriate preventive measures to reduce the incidence of surgical wound infection.

Published: May 2023

Introduction: A sample of the patient's blood is needed to analyse their blood count. Different locations and methods can be chosen to draw blood. Different factors can cause haemolysis to occur when drawing samples. Haemolysis can cause erroneous laboratory results. Methods: A quantitative method has been used. The theoretic part used a descriptive method, and the research used a non-probability research sample. To process the results, Microsoft Office Professional Plus and IBM SPSS have been used. Results: A larger occurrence of haemolytic samples, 34%, has been recorded when drawing blood from the distal part of the arm as opposed to 12% from the cubital part. Furthermore, 32% of samples were haemolytic when drawing blood via vacuum as opposed to 12% when drawing blood via syringe. 36% of samples drawn with smaller intravenous cannulae indicated haemolysis and 14% of samples drawn with larger cannulae. In comparison to drawn samples via syringe and intravenous cannulae haemolysis occurred in 6 and 13% of samples respectively. The cause of 88,8% of haemolytic samples was drawing via an IV cannula and its size. Discussion and conclusion: Haemolysis occurrence is larger especially when drawing blood with smaller IV cannulae and via vacuum, as well as from the distal part of the arm. Over half of haemolytic samples were caused by drawing blood via IV cannula and due to its size.

Investigating the energy, environmental, and economic challenges and opportunities associated with steam sterilisation autoclaves
Authors: O’Callaghan Jordan , Fitzpatrick John , Lalor Fergal , Byrne Edmond
Published: May 2023

Despite steam sterilisation in autoclaves being a common industrial method of sterilisation, very little research has been conducted into quantifying the resources these processes demand and their associated environmental impacts. This paper aims to investigate industrial steam sterilisation in autoclaves with particular application to the biopharmaceutical industry. A mathematical model of a steam autoclave was developed to examine relationships between load size, load material properties and autoclave capacity with energy consumption, environmental impact and cost of sterilisation. The two main energy requirements are thermal energy to produce the clean steam for sterilising, and electrical energy for the vacuum pump. The study showed that thermal energy is dominant, particularly as load increases. The percentage of the maximum load at which the autoclave is operated has a major impact on the specific energy requirement or the energy required to sterilise per unit mass of load. For a given autoclave, the energy requirement increases with increased load but the specific energy requirement decreases. This in turn impacts on the emissions and the energy cost. It is thus shown that it is much more energy efficient to operate at higher loads, making the autoclave much more energy and cost effective, and with less environmental impact. There is potential for applying the analysis presented in this work for conducting optimisation studies for determining the sizes of autoclaves that could minimise the energy requirement, environmental impact and economic cost (3E) of investments for specified load versus time profiles.
Investigating the effect of green composite back sheet materials on solar panel output voltage harvesting for better sustainable energy performance
Authors: AL-Oqla Faris M. , Fares Osama
Published: May 2023

Clean sustainable energy and proper utilization of the available natural resources are of paramount importance for the modern societies. In this work, green composite materials were designed, fabricated and utilized as back sheets for the solar photovoltaic panels to investigate their effects on the output voltage of the solar cell unit. Such replacement of the back sheet of the solar cells would improve their efficiency while reducing the cost and enhancing better environmental conservations. Green back sheet composites were designed with 25 wt% and 50 wt% of high-density polyethylene with all Rhus typhina, Punica granatum and Piper nigrum powders. Investigations of the effect of green composite back sheet materials on solar panel output voltage harvesting have been carried out in Jordan at Zarqa city (latitude 32.07°, longitude 36.08°). Results have revealed that R. typhina and P. nigrum based composites with 25 wt% fiber loading have demonstrated much better output voltage comparable to the original back sheet cell. The maximum output voltage was found to be enhanced about 58 % with the green composite back sheets. This in order would improve the efficiency of such solar cell units and enhance better environmental indices.
Parenting in a new land: the influence of English language proficiency on immigrant parents’ experiences with intergenerational challenges
Authors: Roose Tamara Mae , Lo Meng-Ting
Published: May 2023

The purpose of this survey study was to explore how the English language proficiency of Asian and Latin American immigrant parents influenced their levels of intergenerational challenges as reflected in their experiences with diminished parental authority, role reversal, acculturation gap, value discrepancy, family conflict, and emotional distance. The 86 participants were Asian and Latin American immigrant parents from eight classes at three adult ESL programs in Southern California. They reported lower levels of intergenerational challenges than was expected based on the extant literature, and their experiences were quite similar regardless of their adult ESL class levels. Overall, the parents from different ethnic backgrounds shared more commonalities than differences as language and cultural learners raising children in a new land. This study sheds light on the experience of immigrant parents raising children in ethnic enclaves and pushes against common discourses about immigrants’ acculturation. The findings suggest that preserving their linguistic and cultural heritage has become increasingly important to many immigrant communities and may play a crucial role in how they navigate their roles as parents.
Assessing the determinant factors of risk strategy adoption to mitigate various risks: An experience from smallholder rubber farmers in West Kalimantan Province, Indonesia

Published: May 2023

Over the past decade, smallholder rubber farming experienced significant issues related to risks of rainy season, rubber diseases, and price decreases. The risk exposure will reduce agricultural productivity, income, and sustainability. Farmers are expected to mitigate various risks by adopting the appropriate risk strategy. Efforts to support the risk strategy adoption are constrained by the lack of scientific research in rubber farming, especially for simultaneous risk strategy adoption. This study aims to identify the risk strategy adoption in rubber farming and analyse the determinant factors by considering farmers’ socioeconomic, rubber farm characteristics, and risk perception. The data were collected from 200 rubber farmers in West Kalimantan, Indonesia, and analysed using a multinomial logit model. The study results show that the most selected strategy was income diversification. The multinomial logit model indicates that farmers’ age, family members, rubber age, rubber clones, and rainy season risk perception positively affect the adoption of risk strategy. In contrast, experience, farm area, and farm distance have a negative effect. The results also indicate that family members, farm area, and farm distance variables significantly affect all choices of risk strategy adoption. The results of this study suggest several implications for government and policymakers in providing assistance and counselling, capital assistance, input access, and improving transportation, road access, and communication.

Journeys Into Night: Agewise Cinematic Constructions in Cas and Dylan and Our Souls at Night
Authors: Cristian Réka M.
Published: May 2023

Ashton Applewhite, American writer, activist, blogger and expert on ageism, the author of This Chair Rocks: A Manifesto Against Ageism (2016), remarked in her 2017 TED (Technology, Entertainment, Design) series lecture “Let’s End Ageism” that today when the aged population is, according to the United Nations statistics, at its highest level in human history, in most societies, including developing and the developed countries alike, “people are living longer and societies are getting grayer; you read and hear about it on all media platforms and outside of them.” This essay will be about a slice of these platforms tackling cultural narratives involving longevity and ageing―and their subsequently increased visibility on the silver screen. In order to investigate ageing as a marker of life course identities in two cinematic matching and mismatching journeys into ageing, I have chosen two North American movies presented in the past five years, the Canadian-made Cas and Dylan (2013) directed by Jason Priestley and with Richard Dreyfuss and Tatiana Maslany in leading roles, and the US-produced Our Souls at Night (2017), directed by Ritesh Batra, featuring in the main roles Jane Fonda and Robert Redford. I am interested to see the ways in which the representation of senior citizens―in the above-mentioned movies all being members of the North American Baby Boomers generation―is challenging the cultural myths of aging through various acts of performativity.

The Brief Wondrous Life of Oscar Wao: No Way Out but into the Cane Fields
Authors: McCurdy Carol
Published: May 2023

The essay will focus on one aspect of Diaz’s symbolic representation of the fuku: the sugar cane fields of the Dominican Republic. What better place to address the curse of the diaspora, which all comes from “the same doomed, oppressive history that brought Columbus’ ships to America five hundred years ago” (Patteson 3). Much of the Dominican Republic’s traumatic history can be traced to its exportation of sugar grown in the cane fields, and to the brutality that occurred in these fields. In order to address the curse, Yunior structures the de Leon story around the Dominican cane fields that are central to the fuku and part of the Caribbean imagination.

A Fruitful Two Way Relationship: Arthur Miller and Irish Theatre
Authors: Kurdi Mária
Published: May 2023

The essay investigates the mutual relationship between Miller and Irish theatre life under a title that takes its cue from Two Way Mirror, attempting to highlight the number of ways in which the two sides, mirror-like, reflect on each other. I believe that considering them together may illuminate certain, not so obvious aspects or components of both while suggesting new paths for research
"A Question of Pigment?" The Representation of Mexicans in the Depression Art of Dorothea Lange
Authors: Szente-Varga Mónika
Published: May 2023

Dorothea Lange was a US documentary photographer who earned national recognition during the Depression era. Her picture of Florence Thompson and her children known as Migrant Mother (1936) has become an iconic depiction of the age, of the distressed reality of a sacred relationship that represented not only the devastating present of the farm workers during the 1930s but also the threat of a hopeless future for these people—and the whole nation. The essay investigates how she managed to divulge personal realities beyond the surface of pigmentation, even if this meant that she did not fully comply with the expectations of the FSA. Lange’s art portrayed the human condition of migranthood, homelessness, unemployment, poverty, hunger, deprivation, despair, loneliness, and bleakness she had encountered in the American landscape as universal and ubiquitous, a condition that causes immense sadness, pain and desolation in the human soul, irrespective of one’s racial background.
Hugh MacDiarmid’s Influence on the Scottish Literary Revival
Authors: Szamosi Gertrúd
Published: May 2023

The interwar period of national revival produced a great variety of literary, critical, social, political and philosophical writings that have commonly been referred to as “The Scottish Renaissance.” The term was first used in its new sense in the first issueof The Scottish Chapbook of August 1922, published by Christopher Murray Grieve,better known by his pen name, Hugh MacDiarmid. In comparison with earlier attempts to renew Scottish culture, the single most distinctive feature of this movement was the belief that “there could be no regeneration of the nation’s artistic culture which did not also involve the regeneration of the social, economic and political life of the nation”(McCulloch xiii).
Having It Both Ways? Sympathy and Self-Love in Thomas Jefferson’s Moral Philosophy
Authors: Vajda Zoltán
Published: May 2023

A long-time concern in literary studies, the sentimental conception of sympathyas a subject of scholarly inquiry, has recently also become a subject of Americancultural and intellectual history. Derived from eighteenth-century English empiricalpsychology, the theory of the senses and Scottish moral philosophy, sensibility andsentimentalism soon emerged giving priority to feeling and the senses over reasonand rationality.
