You better stop hiding your true self! The relationship between perceived false self, academic burnout, and mental health problems
Authors: Tomaszek Katarzyna
Published: September 2023

Introduction: False self is defined as the discrepancy between what we show and what we truly think and feel, and is associated with mental health and social problems. The present study aimed to examine the perception of false self-relationships with emotions, and educational and mental health problems. Specifically, the mediation effects of emotional regulation strategies and academic burnout on the association between perceived false self and depressive symptoms as well as life satisfaction were tested.
Material and methods: The study design was cross-sectional. A paper-pencil method of data collection was used. The survey included the Academic Burnout Inventory (MBI-SS), the Perceived False Self Scale (POFS), the Depressive Symptoms Questionnaire (CES-D), and the life satisfaction scale (SWS). A total number of 149 participants took part in this study (aged: M=21.09; SD=1.72; 84.6% women).
Results: The findings indicate that the perceived false self, emotional suppression, cognitive reappraisal, and academic burnout explain 31% of depressive symptoms and 31% of life satisfaction. The perceived false self was associated indirectly with depressive symptoms and life satisfaction via (1) emotional suppression, (2) academic burnout, and (3) emotional suppression, cognitive reassessment, and academic burnout altogether.
Conclusions: Findings confirmed that inauthenticity is connected to mental health impairment and educational problems. Hiding the true self is associated with the suppression of true emotions, and for this reason, a person may experience tension. Consequently, a long-term struggle with distress generates burnout syndrome and an increased risk of mental health problems. In preventive interventions, it is important to include actions that strengthen authentic responses.

Authors: Peate Ian
Published: September 2023

Despite preventative measures being undertaken, incidents and accidents at work occur. Incidents and accidents are two different things; they are, however, related. This article provides readers with an overview of accidents and incidents, key definitions are offered, and reporting procedures are detailed. Near misses and dangerous occurrences are also discussed. It is important that accidents, incidents, dangerous occurrences and near misses are reported and acted upon. In some instances, this is a statutory requirement that employers and employees must adhere to. The article provides an example of an incident report.
Comparative Analysis of Exceptions to Planning in the U.S. and South Korea
Authors: Jeon Jinwon
Published: September 2023

Urban planning involves determining in advance the developmental requirements for a specific geographic area. In this regard, the functions of Korea's urban management plan—especially, the special purpose area—and the U.S. zoning are comparable. However, it is debatable whether the special purpose area and zoning can be comprehended at the same—or comparable—level. Additionally, their mutual differences can be studied from the marginal aspect of both institutions, that is, the admissibility of exceptions to the existing plan and the means and procedures for allowing exceptions. In short, zoning in the U.S. can permit exceptions to application through variance or special permit for individual cases even if the contents of zoning itself are not modified. However, In Korea, it is impossible to grant these exceptions through individual administrative procedure without the procedure for modification and change in the urban management plan itself. Examining the contexts in which each system is situated in both countries explains this difference. As a “safety valve” to ensure the legitimacy of zoning, which is an intervention and limitation on property rights in the U.S., exceptional measures, such as variance and special permit, are necessary. From this protective viewpoint, it is also possible to infer the reason for the generous practice of the grant of variance. Additionally, the essence of variance or special permit must be comprehended through a comprehensive approach to the U.S. context in terms of the distribution of planning authority, standards for judicial review, and participatory factors. In this regard, it can be inferred that the need for exceptional measures similar to those in the U.S. was relatively less in Korea, where the protection of property rights is relatively weaker and urban management plans are acknowledged to have significant binding power.
Scope and exceptions to acceptance Adjudication Prior to Compensation
Authors: Shin Jun Seob
Published: September 2023

The Supreme Court has ruled that compensation for land acquisition and for public projects under the Act on Acquisition and Compensation of Land for Public Works Projects must be adjudicated by the Land Tribunal. It has been determined that compensation claimants cannot directly claim compensation from the project operator without following the adjudication process. This rationale, known as the principle of “adjudication prior to compensation” has been gradually extended to areas such as business compensation, agricultural compensation, as well as compensation for livelihoods. At the same time, the Supreme Court has indicated that for compensation items such as relocation expenses and moving costs within the category of compensation for livelihoods, the principle of adjudication prior to compensation does not apply. This implies that affected parties can directly claim compensation through individual lawsuits without waiting for the Land Tribunal's adjudication, or the project operator can proceed with compensation according to the Land Compensation Act. When comparing the legal nature of compensation categories such as business compensation and agricultural compensation, where the principle of adjudication prior to compensation applies, with categories such as relocation expenses and moving costs, it becomes evident that they all fall under indirect compensation for livelihoods. There is little relevance between the application of the principle of reconsideration prior to compensation and the issue of whether appraisal is required for compensation. This clarifies that the scope of application of the principle of adjudication prior to compensation is determined not by the legal nature or characteristics of compensation categories, but by the Supreme Court's judgment aimed at resolving fundamental inconsistencies between the land compensation system and the practice to achieve concrete validity. Based on the Supreme Court's principle of adjudication prior to compensation, to unify the compensation process for all land compensation categories, including items such as relocation expenses, it becomes necessary to interpret the scope of “adjudication” more expansively within the principle of adjudication prior to compensation. This may involve interpreting Article 50, Paragraph 1, Subparagraph 2 of the Land Compensation Act to allow the Land Tribunal to make increased adjudication for “loss compensation,” even without individual applications for adjudication, to account for items such as relocation expenses. However, this would still necessitate changing existing practical norms and procedures. Considering these points, the Supreme Court's principle of adjudication prior to compensation appears to be applicable only in specific circumstances, and extending it to the entire land compensation process seems impractical.

Published: September 2023

Today's challenge is to produce a biodegradable materials for packing which can partially replace traditional plastic materials. Starch-based biodegradable plastics are less harmful to the environment and breakdown faster than regular plastics. The goal of this research was to produce and characterize a biodegradable film(BF) made from Sorghum bicolor (L.) starch and glycerol plasticizer. The produced film contained two amounts of Sorghum bicolor (L.) starch (5 g and 10 g) and three percentages of glycerol (25%, 30%, and 40%). The Sorghum bicolor (L.) and biodegradable glycerol-based plastic film had the lowest density, water absorption, and thickness swelling of 0.99 g cm-3, 55.72%, and 10.72%, respectively. The tensile strength is maximum at 9.97 MPa and and elongation obtained is 23.84%. The Sorghum bicolor (L.) starch and glycerol-based biodegradable film decomposed by 69.23% after biodegradability testing of one week.
Measurement of the thickness and refractive index of a thin film by analyzing reflected interference fringes
Authors: Kim Deok Woo , Kwon Minjae , Park Soobong , Kim Byoung Joo , Cha Myoungsik
Published: September 2023

We propose a novel, to the best of our knowledge, method to estimate the thickness and refractive index of a thin film by analyzing the reflectance as a function of the incidence angle. In most cases, interference fringes cannot be obtained from a film within a practical angular range unless it is much thicker than the wavelength. This problem was solved by adopting a high-index material as the medium of incidence, in which case several cycles of interference fringes were observed within a small range of incidence angles near the critical angle, allowing a fringe analysis. Consequently, the thicknesses, as well as the refractive indices of dielectric thin films, could be estimated. Our proposed method gave uncertainties of 20 nm and 0.0004 for the thickness and refractive index measurements, respectively.

Published: September 2023

Optical frequency combs based on fiber lasers mode-locked (ML) with a nonlinear amplifying loop mirror (NALM) have become the backbone of many cutting-edge applications, ranging from precision spectroscopy to quantum physics. Being extremely precise measurement tools, understanding their passive stability and low-noise operation regimes is vital. While several influences on the laser noise have been studied, many parameters remain poorly understood. Here, we systematically analyze under which preconditions the artificial saturable absorber settings of the laser can be modified during operation without losing mode-locking and the effects on laser noise, the spectrum and the output power. Our results show that it is possible to decrease the amplitude noise (AM noise) of the laser by more than 50 % by simply rotating a wave plate within the laser cavity. Additionally, we discuss differences to a similar effect observed in a NALM-alike laser amplifier and of changing the output coupling. These findings deepen our understanding and capabilities of optimizing the noise performance of ML fiber lasers, enable us to investigate new parameter spaces, and can be used to further optimize the noise performance of the NALM laser design, making it an ideal light source for advanced setups both in research and industry.

Published: September 2023

Er3+-doped glass and fiber are very attractive for near-infrared (NIR) lasers and photonic applications. In this work, the full width at half maximum (FWHM) of NIR fluorescence emission of the Er3+-doped germanate glass can be broadened from 72 to 99 nm when Al2O3 was added. In addition, the spectroscopic properties, including absorption and emission spectra, Judd–Ofelt intensity parameters, absorption and emission cross sections, gain coefficient, and fluorescence lifetime, of the Al2O3-modified germanate glass were systematically investigated. What is more, silicate-clad heavily Er3+-doped germanate core multimaterial fibers were successfully drawn by a rod-in-tube method. Notably, broadband NIR amplified spontaneous emission (ASE) with an FWHM of 120 nm was achieved in this new fiber. To the best of our knowledge, this is the largest FWHM reported for Er3+-doped germanate glass fibers. These results suggest that the as-drawn Er3+-doped germanate glass fiber with superior performances is a promising candidate for broadband optical amplification.

Sesame is an important oilseed crop cultivated in Ethiopia as a cash crop for small holder farmers. However, low yield is one of the main constraints of its cultivation. Boosting and sustaining production of sesame is thus timely to achieve the global oil demand. This study was, therefore, aimed at identifying mutant genotypes targeted to produce better agronomic traits of M2 lines on fourteen Ethiopian sesame genotypes through seed treatment with chemical mutagens. EMS was used as a chemical mutagen to treat the fourteen sesame genotypes. Quantitative and qualitative data were recorded and analyzed using analysis of variance with GenStat 16 software. Post-ANOVA mean comparisons were made using Duncan’s Multiple Range Test (p≤ 0.01). Statistically significant phenotypic changes were observed in both quantitative and qualitative agronomic traits of the M2 lines. All mutant genotypes generated by EMS treatment showed a highly significant variation for the measured quantitative traits, except for the traits LBL and LTL. On the other hand, EMS-treated genotypes showed a significant change for the qualitative traits, except for PGT, BP, SSCS, LC, LH and LA traits. Mutated Baha Necho, Setit 3, and Zeri Tesfay showed the most promising changes in desirable agronomic traits. To the best of our knowledge, this study represents the first report on the treatment of sesame seeds with EMS to generate desirable agronomic traits in Ethiopian sesame genotypes. These findings would deliver an insight into the genetic characteristics and variability of important sesame agronomic traits. Besides, the findings set up a foundation for future genomic studies in sesame agronomic traits, which would serve as genetic resources for sesame improvement.
What’s the impact of voice-hearing experiences on the social relating of young people: A comparison between help-seeking young people who did and did not hear voices

Published: September 2023

Limited research has explored the specific impact of voice-hearing experiences upon the social relating of adolescents. This study examined the associations of voice-hearing in youth with social relating, and putative explanatory factors. An observational, cross-sectional design using a clinical comparison group was employed to examine historical and concurrent associations with voice-hearing. Thirty-four young people (age 14–18 years) with voice-hearing experiences and 34 young people who did not hear voices were recruited from NHS mental health services. Participants completed measures about social relating and potential explanatory factors. Analyses of covariance were used to examine between-group differences. Voice-hearers scored higher on negative schematic beliefs (self-beliefs, partial η2 = .163, p = .001; other-beliefs, partial η2 = .152, p =. 002) and depressive and anxiety symptoms (partial η2 = .23 and partial η2 = .24, p-s <. 001 respectively). The two groups did not differ significantly on childhood trauma levels (partial η2 = .02, p = .273), however, the voice-hearing group scored lower on premorbid adjustment (partial η2 = .19, p < .001). Hearing voices in help-seeking youth could be an indicator for social relating issues and holding negative schematic beliefs, and may be an indicator for of increased psychopathological complexity. Although poorer premorbid adjustment might indicate an early vulnerability to social relating difficulties, voice-hearing might be an aggravating factor and one that requires treatment.
Research on cloud manufacturing service recommendation based on graph neural network
Authors: Li Minghui , Shi Xiaoqiu , Shi Yuqiang , Cai Yong , Dong Xuewen
Published: September 2023

There are an increasing number of manufacturing service resources appeared on the cloud manufacturing (CMfg) service platform recently, which leads to a serious information overloading problem to the enterprises that need these resources. To tackle this problem, a graph neural network-based recommendation method for CMfg service resources is proposed, which effectively overcomes some limitations of the traditional recommendation methods. Specifically, we first use different similarity calculation methods (e.g., Cosine similarity, Pearson correlation coefficient, etc.) to calculate the similarities between different resources based on the feature information of CMfg service resources. A resource graph dataset is accordingly established. A graph neural network is then used to perform representation learning of nodes in these graphs, obtaining the vector representations of these nodes. Finally, new links that may appear in a graph are predicted by performing dot product calculations on these nodes’ vector representations. And these links can be used to recommend suitable resources. Experiments mainly show that (i) the proposed method obtains better link prediction accuracy compared with that of other link prediction algorithms; (ii) when the network density used for training is relatively high, the predictive performance of the proposed method is improved significantly. Our method can shed light on how to choose suitable CMfg service resources from the CMfg service platform.

Published: September 2023

Background and Aim: Fatty liver disease is a common condition, characterized by excess fat accumulation in the liver. It can contribute to more severe liver-related health issues, making it a critical concern in avian and human medicine. Apart from modifying the gene expression of liver cells, the disease also alters the expression of specific transcript isoforms, which might serve as new biological markers for both species. This study aimed to identify cross-species genes displaying differential expressions in their transcript isoforms in humans and chickens with fatty liver disease.

Materials and Methods: We performed differential gene expression and differential transcript usage (DTU) analyses on messenger RNA datasets from the livers of both chickens and humans with fatty liver disease. Using appropriate cross-species gene identification methods, we reviewed the acquired candidate genes and their transcript isoforms to determine their potential role in fatty liver disease’s pathogenesis.

Results: We identified seven genes - ALG5, BRD7, DIABLO, RSU1, SFXN5, STIMATE, TJP3, and VDAC2 - and their corresponding transcript isoforms as potential candidates (false discovery rate ≤0.05). Our findings showed that these genes most likely contribute to fatty disease development and progression.

Conclusion: This study successfully identified novel human-chicken DTU genes in fatty liver disease. Further research is encouraged to verify the functions and regulations of these transcript isoforms as potential diagnostic markers for fatty liver disease in humans and chickens.

Keywords: cross-species biomarkers, differential gene expression, differential transcript usage, fat metabolism, fatty liver disease, lipidosis, transcript isoforms.

Published: September 2023

Background and Aim: The high diversity of Aeromonas spp. results in various pathogenicity levels. This group of bacteria causes a serious disease named motile Aeromonas septicemia (MAS) in catfish (Clarias spp.). This study aimed to characterize the species and virulence gene diversity of Aeromonas spp. isolated from diseased catfish.

Materials and Methods: Nine Aeromonas spp. were isolated from infected catfish cultivated in Java, Indonesia, and they were identified at the phenotypic and molecular levels (16S rDNA). The virulence genes assessed included aer/haem, alt, ast, flaA, lafA, and fstA.

Results: Phylogenetic analysis identified nine isolates of Aeromonas spp.: Aeromonas hydrophila (11.11%), Aeromonas caviae (11.11%), Aeromonas veronii bv. veronii (44.44%), and Aeromonas dhakensis (33.33%). Virulence genes, such as aer/haem, alt, ast, flaA, lafA, and fstA, were detected in all isolates at frequencies of approximately 100%, 66.67%, 88.89%, 100%, 55.56%, and 66.67%, respectively. This study is the first report on A. dhakensis recovered from an Indonesian catfish culture. Furthermore, our study revealed the presence of A. veronii bv veronii, a biovar that has not been reported before in Indonesia.

Conclusion: This finding confirms that MAS was caused by multiple species of Aeromonas, notably A. dhakensis and A. veronii bv veronii, within Indonesian fish culture. The presence of these Aeromonas species with multiple virulence genes poses a significant threat to the freshwater aquaculture industry.

Keywords: 16S rDNA, aeromoniasis, motile Aeromonas septicemia, pathogenicity, phenotype, phylogenetic.

Authors: Medaglia Juliana , Silveira Carlos Eduardo , Gandara José Manoel Gonçalves
Published: September 2023

O presente artigo aborda o contexto de criação e desenvolvimento dos cursos superiores de turismo em nível de graduação no Brasil, considerando desde as influências sofridas pela realidade estrangeira já no surgimento do ensino superior brasileiro, até as influências das políticas nacionais de educação e de turismo sobre os cursos de turismo, ocorridas ao longo das últimas décadas a partir da criação da EMBRATUR. O objetivo central do artigo foi levantar e discutir o contexto em que o surgimento e a multiplicação de cursos superiores de turismo aconteceram no Brasil e, com especial enfoque nas políticas, as influências sobre o mercado de trabalho e a consolidação de uma área acadêmica. A pesquisa foi bibliográfica e documental e teve caráter exploratório, a fim de propiciar a discussão do tema sem estabelecimento de hipóteses. Entre as conclusões destaca-se que a formação em turismo teve sobrecarga na oferta, especialmente nos anos 1990, em alguns casos apresentou caráter eminentemente operacional em consonância com o período histórico vigente, foi influenciada pelas políticas públicas mais do que as influenciou e, especialmente, vem se consolidando como uma área do saber mais do que uma área profissional.
ANÁLISE DA IMAGEM DO BRASIL POR MEIO DO ANHOLT NATION BRANDING INDEX
Authors: Mariutti Fabiana Gondim , Giraldi Janaina de Moura Engracia
Published: September 2023

O turismo está em plena expansão no mercado mundial, com um crescimento acelerado previsto para esta nova década. Relacionado a tal fato, o Brasil se posiciona com representatividade pouco explorada comercialmente no cenário turístico internacional. A consideração da marca-país, como sendo a percepção da imagem e as associações da marca de uma nação - vista pelos estrangeiros, está freqüentemente presente, seja no panorama político, econômico, social, acadêmico, na moda, no esporte, no cinema e, finalmente no turismo. Neste contexto, o objetivo desta pesquisa é avaliar a imagem do Brasil a partir do Anholt Nation Branding Index, servindo como um importante subsídio na avaliação da marca Brasil no exterior. A metodologia utilizada foi descritiva e quantitativa, por meio de análise de dados secundários, baseada na pontuação das seis dimensões consideradas pelo Index: Pessoas; Produtos; Governo; Turismo; Cultura; Imigração e Investimento. Após tabular a pontuação destas dimensões dadas pelos quatro países Japão, China, Estados Unidos da América e Reino Unido sobre a imagem do Brasil, chegou-se à descoberta que Produtos e Governo obtiveram a maior pontuação, seguido de Pessoas, Imigração e Investimento e Turismo. A mais baixa pontuação em comum para todos os países foi a Cultura. Conclui-se, adicionalmente, que a dimensão do Index Turismo, enquanto variável para avaliação da imagem do Brasil, precisa ser trabalhada a partir da marca Brasil e sua respectiva construção e comunicação no mercado internacional para melhorar sua exposição e prospectar turistas.

É inquestionável a necessidade da comunicação nas relações humanas e sociais. As organizações são coletividades de pessoas especializadas na produção de bens e serviços, cuja constituição e o desenvolvimento fundamentam-se na comunicação. Muitos dos problemas e desafios organizacionais são, entretanto, originados da falta ou da dificuldade de comunicação. O sucesso da implementação de propostas de desenvolvimento do turismo depende da consistência, da clareza e da eficácia da comunicação entre os atores e as comunidades responsáveis pelo setor, visando à sua participação e ao seu comprometimento com as decisões e realizações. O objetivo deste artigo é mostrar a importância do Observatório de Turismo e Cultura da Serra Gaúcha (Observatur) para a comunicação entre os atores do turismo regional. A região é um dos cinco principais destinos turísticos do Brasil. Para a realização do estudo, de natureza descritiva e exploratória, além de observação direta e observação participante, fez-se revisão de relatórios e de históricos do Observatur. Em razão da série de atividades inéditas realizadas pelo Observatur, verificam se avanços nas propostas de integração regional por meio da comunicação entre os atores do turismo da região da Serra Gaúcha.
TURISMO EMISSIVO BRASILEIRO – UMA ANÁLISE COM MODELOS DE DADOS EM PAINEL
Authors: Meurer Roberto
Published: September 2023

O número de brasileiros viajando ao exterior como proporção da população é pequeno em comparação com o mundo. Apesar disso, as despesas com viagens representam importante parcela das despesas com serviços no balanço de pagamentos. Neste trabalho, os determinantes do número de brasileiros viajando ao exterior são estimados por meio de modelos em painel, utilizando produto interno bruto do Brasil e a taxa de câmbio da moeda brasileira em relação aos países de destino como variáveis explicativas. São utilizados os dados para os 12 países que recebem o maior número de brasileiros, de 2004 a 2008. Os resultados indicam que há um forte componente autorregressivo no número de viajantes, o que é compatível com a formação de hábito. A reação do número de brasileiros viajando ao exterior é inelástica à taxa real de câmbio. Quando utilizados os dados para os quatro países que recebem o maior número de viajantes brasileiros, Argentina, Estados Unidos, Chile e Uruguai, a relação entre câmbio real e número de viajantes permanece inelástica, mas a relação com a renda dos brasileiros é elástica. Estes resultados são importantes para o planejamento da oferta de serviços de turismo emissivo e doméstico, substituto do turismo internacional. A influência das variáveis macroeconômicas para o comportamento do número de viajantes é especialmente importante, considerando o regime de câmbio flutuante, que leva a oscilações no número de viajantes.
Dancing Relational Bodyhood
Authors: Lee Heunjung
Published: September 2023

In contrast to the idea of disability-free aging as 'positive' and 'successful' aging, ill, impaired, older persons who are 'dependent' (physically, socially, economically) are often devalued and stigmatized in ageist and ableist societies. Tracing the extraordinary life course and artistic practices of Tuuli Helkky Helle (1933-2018), an older Finnish dancer who lived with cerebral palsy, this paper highlights how she reclaimed 'dependency' as a positive term and visualized the beauty and power of the interconnected, interrelated, and caring relationships in her arts and life. From her 60s until her 80s, as an artist and activist, she participated in various dance pieces, radical nude photography series, and activist performances for older adults with disabilities. This article is the first academic article that documents her remarkable works and examines her dancing body. Drawing on the theoretical perspective of Ann Cooper Bright (2017; 2019) about gravity, interconnectedness, and disabled and aged bodies and Pia Kontos's notion of "relational citizenship" (2017), this paper illuminates the alternative danceability of the aged-disabled body.
Queering Time, Questioning Ageism Through Speculative Siction
Authors: Oró-Piqueras Maricel , Falcus Sarah
Published: September 2023

Speculative narratives offer particularly rich and complex explorations of time and aging, exhibiting a tendency to play with 'queer temporalities' and imagine the lifecourse and human chronology in alternative ways. In this article, we employ an ageing studies perspective in our analysis of time, the lifecourse and aging in four visual speculative narratives. We focus on recent film/TV about increased longevity/immortality. "San Junipero" (in TV Series Black Mirror, 2016), Mr Nobody (2009) and In Time (2011) imagine societies in which forms of technologically enabled extended longevity have been achieved. The Age of Adaline (2015), on the other hand, follows the tradition of speculative fiction about exclusive immortality, achieved only by one or a small number of persons. All four texts play with linear and chronological aging and juxtapose youth and age in provocative ways, exploiting the possibilities of the visual mode. In Time and Adaline seem to yearn for normative social order and present extended longevity as the source of unhappiness and social crisis. San Junipero and Mr Nobody, on the other hand, focus on the possibilities of temporal disorder as a way of escaping normative expectations. They draw attention to the constricting nature of normative times and combine utopian and dystopian elements to explore the tension between normative and queer temporal orders.

Sind Arbeit und Produktion Mittel des Protests? Ist das Selbstherstellen eine unentdeckte politikwissenschaftliche Kategorie? Jens Thomas analysiert im Spannungsfeld eines Bedeutungsgewinns von Arbeit und eines Ansehensverlusts der Politik bislang unbeachtete Formen der Politikgestaltung und zeigt: Das Politische bahnt sich neue Wege fern eines institutionalisierten Politikbegriffs. Die von ihm in die Forschung eingeführte Kategorie der Politics of Self-Production politisiert Arbeit, entpolitisiert aber auch die Politik - und eröffnet einen neuen Blickwinkel auf die Zusammenhänge zwischen Selbermachen, Designproduktion und Nachhaltigkeit.

Objective Hair loss has been reported to occur during dopaminergic therapy in patients with Parkinson’s disease. The mechanism by which dopaminergic therapy induces hair loss is not well understood. Dopamine receptors are present in the hair follicle, where they regulate melanin production. However, the role of dopamine receptors in hair growth is still not well understood. This study aimed to evaluate the prevalence of hair loss and identify factors associated with complaints of hair loss in patients with Parkinson’s disease.Methods A cross-sectional design involving 495 Parkinson’s disease patients was applied to evaluate hair loss status. Patients completed a questionnaire, and scalp/hair examinations were performed. Patients with underlying conditions that could affect hair loss and those prescribed medications known to increase the risk of hair loss were excluded. Finally, 291 patients (58.8%) were included for analysis.Results Among the 495 patients, 138 (27.9%) reported hair loss. Interestingly, more than half of the patients who complained of hair loss (79 out of 138) did not utilize treatments such as hair products, massage, dietary modifications, or alopecia medications. Hair inspection by a single investigator revealed objective hair loss in 263 patients (53.1%). An analysis of factors associated with hair loss complaints showed that the intake of dopaminergic medications with a levodopa-equivalent daily dose > 448 mg was associated with complaints of hair loss.Conclusion Dopaminergic medication is associated with hair loss complaints in Parkinson’s disease patients.

Objective Emotional processing is a core feature of social interactions and has been well studied in patients with idiopathic Parkinson’s disease (PD), albeit with contradictory results. However, these studies excluded patients with atypical parkinsonism, such as multiple system atrophy (MSA). The objective of this exploratory study was to provide better insights into emotion processing in patients with MSA using eye tracking data.Methods We included 21 MSA patients, 15 PD patients and 19 matched controls in this study. Participants performed a dynamic and a static emotion recognition task, and gaze fixations were analyzed in different areas of interest. Participants underwent neuropsychological testing and assessment of depression and alexithymia.Results MSA patients were less accurate in recognizing anger than controls (p = 0.02) and had overall fewer fixations than controls (p = 0.001). In the static task, MSA patients had fewer fixations (p < 0.001) and a longer time to first fixation (p = 0.026) on the eye region. Furthermore, MSA patients had a longer fixation duration overall than PD patients (p = 0.004) and longer fixations on the nose than controls (p = 0.005). Alexithymia scores were higher in MSA patients compared to controls (p = 0.038).Conclusion This study demonstrated impaired recognition of anger in MSA patients compared to HCs. Fewer and later fixations on the eyes along with a center bias suggest avoidance of eye contact, which may be a characteristic gaze behavior in MSA patients.

Objective Progressive supranuclear palsy (PSP) involves a variety of visual symptoms that are thought to be partially caused by structural abnormalities of the retina. However, the relationship between retinal structural changes, disease severity, and intracranial alterations remains unknown. We investigated distinct retinal thinning patterns and their relationship with clinical severity and intracranial alterations in a PSP cohort.Methods We enrolled 19 patients with PSP (38 eyes) and 20 age-matched healthy controls (40 eyes). All of the participants underwent peripapillary and macular optical coherence tomography. Brain 11C-2β-carbomethoxy-3β-(4-fluorophenyl) tropane (11C-CFT) and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography imaging were also performed in patients with PSP. We investigated the association between retinal thickness changes and clinical features, striatal dopamine transporter availability, and cerebral glucose metabolism.Results The peripapillary retinal nerve fiber layer (pRNFL) and macula were significantly thinner in patients with PSP than in controls. The thickness of the superior sector of the pRNFL demonstrated a significant negative relationship with the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale part III and Hoehn and Yahr staging scale scores. A significant negative correlation was found between outer inferior macular thickness and disease duration. Outer temporal macular thickness was positively correlated with Montreal Cognitive Assessment scores. In PSP, lower outer temporal macular thickness was also positively correlated with decreased dopamine transporter binding in the caudate.Conclusion The pRNFL and macular thinning may be candidate markers for monitoring disease severity. Additionally, macular thinning may be an in vivo indicator of nigrostriatal dopaminergic cell degeneration in PSP patients.

A comprehensive photometric study and evolutionary state for the systems V0487 Lac, V0566 Hya, and V0666 Lac were carried out by means of their first photometric observations. New times of minima were estimated from the observed light curves, and first (O–C) curves were established for all systems. The radiative treatment was carried out using a Windows interface version of the Wilson and Devinney programme (W–D). The adopted models provide some absolute characteristics for the systems under study, which are used to determine the spectral type of the system’s constituents and their evolutionary stage. Distances to each system were calculated, and physical properties were estimated. All system components, with the exception of the secondary component of the system V0487 Lac, showed good fit when the systems were positioned on the theoretical mass–luminosity and mass–radius relations.
Two Types of Neo-Kantianism. The Case of W. E. B. Du Bois’s and Alain L. Locke’s Race Theories
Authors: Cisternino Massimo
Published: September 2023

The paper uses the Neo-Kantian distinction between Natural and Human sciences and its methodological implications to navigate W. E. B. Du Bois’s and Alain L. Locke’s theories of race. In tracing a continuity between these two figures, the paper also shows how their respective reliance on Neo-Kantian categories leads them to different results. The goal is to show how, while Du Bois’s Neo-Kantianism is best understood as a Diltheyan Neo-Kantianism of the psycho-physical unity of human nature influenced by an anti-metaphysical orientation, Locke’s Neo-Kantianism can be seen as a Neo-Kantianism whose focus is the rejection of causality and of the causal nexus between biological and non-biological traits.

Background

Ovarian cancer is a prominent cause of mortality among women worldwide. A kinase anchor protein 12 (AKAP12) has been investigated, but its contribution to ovarian cancer is unclear.

Objectives

This study comprehensively investigates the role of AKAP12 in ovarian cancer proliferation by elucidating its underlying mechanisms and functions.

Methods

We compared the expression levels of AKAP12 in ovarian cancer and adjacent tissues. We subsequently established A2780 and HO8910 cell lines that have undergone AKAP12 overexpression or knockdown to verify the function of AKAP12 in ovarian cancer. To determine the effect of AKAP12 on tumorigenicity, migration, and invasion, we performed CCK-8, colony-formation, xenograft models, transwell, and wound healing assays. Furthermore, we used pathway enrichment analysis to identify Hippo signaling related to AKAP12 overexpression. Then we characterized the relevance of Hippo signaling in AKAP12-regulated tumor suppressive effects in ovarian cancer through western blot.

Results

Our study revealed a significant decrease in AKAP12 expression in ovarian cancer samples. Moreover, functional assays demonstrated the tumor suppressive effects of AKAP12 overexpression, inhibiting cancer cell proliferation, migration, and invasion. Consistent with these findings, mice inoculated with AKAP12-overexpressing cells exhibited slower tumor growth in our mouse xenograft model. We also observed a positive relationship between AKAP12 overexpression and Hippo pathway-related proteins.

Conclusions

AKAP12 plays a crucial role in the suppression of ovarian cancer through activation of the Hippo signaling pathway. Furthermore, it could be a potential target for developing new therapeutic strategies for ovarian cancer treatment.

Central European populations of silver fir (Abies alba Mill.) grow under a relatively wide amplitude of environmental conditions. Assuming that forest tree stands are locally adapted, the use of forest reproductive material from sites with limited water availability is expected to increase drought tolerance in future forests. At the same time, genetic diversity is of utmost importance as the basis of adaptation to a changing environment. Currently, a selection of potential sources for climate-smart reproductive material of silver fir is under way in Southern Germany. It is based on a multidisciplinary approach elucidating the genetic variation, site conditions, as well as tree resilience based on a dendroecological approach. The analysis encompasses a large number of stands representing the whole range of the species’ ecological requirements. The population genetic analysis based on molecular markers (nuclear microsatellites) provided important information concerning the gene pool of the species in Southern Germany. On one hand, it revealed genetic differentiation and transition zones between western and eastern clusters. On the other hand, the results indicated gradients and regional variation of genetic diversity. These patterns can be explained by post glacial recolonization and the peripheral character of the species at the northern limit of its distribution. Together with the outcomes of the site condition and dendroecological approaches, the results of the genetic analysis will be used to inform future provenance recommendations.
