Published: August 2023

The objective of this study was to determine the risk factors for skin alterations at herd and cow level on dairy farms with different housing systems in South Tyrol (Northern Italy). A cross-sectional study was conducted on 204 farms (111 free stalls and 93 tie stalls) from March to October 2019 assessing the level of animal welfare using resource-based and animal-based indicators. A total number of 1,891 dairy cows were evaluated, of which 43.5% were reared in tie stalls and 56.5% in free stalls. A logistic regression model identified the herd and cow level risks factors for neck and leg skin alterations in the two different systems. There was a higher prevalence for skin lesions on the neck (Odd Ratio (OR) = 2.36) and hock (OR = 2.82) for tie stalls. Irrespective of the housing system the soft-based stall mattresses had a lower prevalence for knee and hock lesions of 0.48 and 0.54, respectively, compared to wood base stalls for both knee (OR = 2.19) and hock (OR = 2.47) consecutively. The prevalence of skin alterations on the knee (OR = 0.42) and hock (OR = 0.33) decreased by the presence of sawdust as bedding material. Similarly, straw (OR = 0.61) and lime-straw-water bedding (OR = 0.59) reduced the prevalence for skin alterations on the hock. Access to pasture reduced the prevalence of skin alterations on the neck (OR = 0.34), the knee (OR = 0.77), and on the hock (OR = 0.46) regardless of the housing system. In conclusion, the assessment of risk factors of different skin alterations in different housing systems can contribute to the improvement of overall animal welfare in traditional small scale mountain dairy systems.

The rapid emergence and global dissemination of SARS-CoV-2 that causes COVID-19 continues to cause an unprecedented global health burden resulting in nearly 7 million deaths. While multiple vaccine countermeasures have been approved for emergency use, additional treatments are still needed due to sluggish vaccine rollout, vaccine hesitancy, and inefficient vaccine-mediated protection. Immunoadjuvant compounds delivered intranasally can guide non-specific innate immune responses during the critical early stages of viral replication, reducing morbidity and mortality. N-dihydrogalactochitosan (GC) is a novel mucoadhesive immunostimulatory polymer of β-0-4-linked N-acetylglucosamine that is solubilized by the conjugation of galactose glycans with current applications as a cancer immunotherapeutic. We tested GC as a potential countermeasure for COVID-19. GC was well-tolerated and did not produce histopathologic lesions in the mouse lung. GC administered intranasally before and after SARS-CoV-2 exposure diminished morbidity and mortality in humanized ACE2 receptor expressing mice by up to 75% and reduced infectious virus levels in the upper airway. Fluorescent labeling of GC shows that it is confined to the lumen or superficial mucosa of the nasal cavity, without involvement of adjacent or deeper tissues. Our findings demonstrate a new application for soluble immunoadjuvants such as GC for preventing disease associated with SARS-CoV-2 and may be particularly attractive to persons who are needle-averse.

Published: August 2023

In recent years, the prevalence of T2DM has been increasing annually, in particular, the personal and socioeconomic burden caused by multiple complications has become increasingly serious. This study aimed to screen out the high-risk complication combination of T2DM through various data mining methods, establish and evaluate a risk prediction model of the complication combination in patients with T2DM. Questionnaire surveys, physical examinations, and biochemical tests were conducted on 4,937 patients with T2DM, and 810 cases of sample data with complications were retained. The high-risk complication combination was screened by association rules based on the Apriori algorithm. Risk factors were screened using the LASSO regression model, random forest model, and support vector machine. A risk prediction model was established using logistic regression analysis, and a dynamic nomogram was constructed. Receiver operating characteristic (ROC) curves, harrell’s concordance index (C-Index), calibration curves, decision curve analysis (DCA), and internal validation were used to evaluate the differentiation, calibration, and clinical applicability of the models. This study found that patients with T2DM had a high-risk combination of lower extremity vasculopathy, diabetic foot, and diabetic retinopathy. Based on this, body mass index, diastolic blood pressure, total cholesterol, triglyceride, 2-hour postprandial blood glucose and blood urea nitrogen levels were screened and used for the modeling analysis. The area under the ROC curves of the internal and external validations were 0.768 (95% CI, 0.744−0.792) and 0.745 (95% CI, 0.669−0.820), respectively, and the C-index and AUC value were consistent. The calibration plots showed good calibration, and the risk threshold for DCA was 30–54%. In this study, we developed and evaluated a predictive model for the development of a high-risk complication combination while uncovering the pattern of complications in patients with T2DM. This model has a practical guiding effect on the health management of patients with T2DM in community settings.

Background:COVID-19 pandemic calls into question whether AD and Very-late-onset­ schizophrenia-like psychosis (VLOSL): "dementia praecox" have higher COVID-19 risk and whether lnflammasome-Cytokine-insulin signaling casade (IFCI) mediates the dementia and psychosis link.Our
objective is : 1) to conduct Pub-med search for IFCI) in AD, VLOSL and COVID-10 burden; 2a)to conduct post-hoc RCT analysis of Ginseng effect regarding cognitive impairment correlates with insulin resistance(IR) and cardio-metabolic risks (CMR) in schizophrenia
Result: In Part1: our Pubmed search concludes Dementia syndrome carries higher mortality risk. A meta-analysis of 634,338 COVID-19 patients from 16 studies reveals that schizophrenia, and dementia, significantly increased risk of COVID-19 mortality and severity. Cardio-metabolic risk factors modify the link. A large Swedish cohort study and systematic review of 17studies found evidence of VLOSL carries higher risk of dementia. Aberrant IFCI correlated with COVID-19 severity. Effect sizes cannot be calculated due to sample heterogeneity. In Part 2: post-hoc analysis of Ginsana-115 (Boehringer-lngelheim-Pharmaton,Switzerland) of 8-week placebo­ controlled parallel group design in TRS subjects . Log-lR(insulin resistance) scores significantly correlated with spatial processing (p=0.017). Framingham-Risk-score correlated inversely with visual perception p = 0.040) and spatial processing (p=0.029) and neurocognitive index (p=0.090). Systolic blood pressure (sBP) correlated significantly and inversely with visual perception (p=0.032),speed (p=0.010),, spatial processing (p=0.034), HDL correlated with memory score:p=0.008. Brief­ Psychiatric-Rating-Scale:BPRS correlated significantly with executive reasoning ( p=0.047),memory (p=0.021), and mental inflexibility (p=0.026). Ginsana-115 at 100-mg/200-mg significantly reduced FRS by 24.1% compared with 16.1%(P<0.05) and systolic blood pressure (P<0.05) and significantly improved lipid profile in raising HDL and lowering LDL. Ginsana-115: 100 mg and 200 mg oral dosage, significantly improved negative symptom of apathy akin to AD.
Conclusion: IFCI) appears to link COVID-19 syndrome, VLOSL overlapping with AD. L. Ginsana-115 effects in TRS highlight the therapeutic strategy of Diet, drug leads and Exercise targeting specifically IFCL·Iandscape in COVID-19 syndrome, AD and VLOSL.

The target spot of cucurbits, caused by Corynespora cassiicola, occurs in several cultivated species, being considered an important disease on cucumbers. The objetive was to determine the cucumber response to the target leaf spot as a function of plant age, seeking a better understanding of the pathosystem in orderto avoid economic damages to producers. Cucumber ‘Soldier’ plants were inoculated at 20, 30 and 40 days after sowing. Disease severity was evaluated at three, six and nine days after inoculation of the pathogen; thenumber of leaves and plant height at intervals of 7 to 10 days after inoculation of the pathogen; the number and fresh mass of fruits and the fresh and dry mass of the aerial parts of the plants at 60 days after sowing. A lower disease severity was observed on younger leaves, on plants inoculated at 20 days of age from the sixthday of evaluation, with plants inoculated at 30 days being the most susceptible, reaching 64% disease severity after nine days of inoculation. The variables plant height, number of leaves and fruits, fruit production and fresh and dry mass of the aerial part of the plant were significantly affected by the age of the plant at the timeof inoculation of the pathogen C. cassiicola, with the lowest values, in general, in the youngest inoculated plants, at 20 days, while the 40-day-old plants had the least affected vegetative development and production, evidencing the importance of delaying the entry of the disease in the area.

Published: August 2023

O objetivo deste estudo é analisar, sob uma perspectiva histórica, socioeconômica e política, a realidade na qual a presença masculina no curso de formação inicial de professores pedagogos e a possível atuação docente na educação de crianças pequenas é muito baixa e, por ora, alvo de diversos discursos sociais estereotipados, que sustentam a ideia de não pertencimento. De natureza qualitativa e exploratória, o mesmo, concentra-se no ato de provocar um novo olhar sobre dadas imposições de gênero, que sustentam a ideia estereotipada em relação aos espaços do homem e da mulher no âmbito educacional. Destaca, em especial, que a presença masculina no curso de Pedagogia e no exercício docente na Educação Infantil, ainda é um tabu a ser superado. Aponta que, quando a presença masculina existe nesses espaços, ela é alvo de diversos questionamentos sobre sua moral, ética, profissionalismo e até mesmo sua masculinidade.

This reflective paper aims to explore the best practices for creating an inclusive educational environment, with a focus on children with special health needs (SHN). The study begins with a comprehensive literature review, seeking to identify the key objectives and main ideas in fostering inclusivity. The essential steps for establishing an inclusive environment are outlined, such as rejecting stereotypes, fostering collaboration, and instilling self-belief within the school community. To ensure inclusivity in mainstream educational institutions, the study emphasizes the recognition of diverse teaching approaches tailored to different learning styles, temperaments, and individual personalities of children. It also highlights the importance of adapting instructional materials and promoting independent choices by students within the classroom. Collaboration, support, and varied activities suitable for each child's developmental level are essential components of an inclusive educational setting. The paper further emphasizes the significance of a planned and organized physical space, a supportive social and emotional climate, and opportunities for collaborative work among children to achieve positive outcomes. Additionally, it underscores the importance of informing society about individuals with SHN, enhancing social readiness for integration and reducing dissatisfaction. Working with parents of children with SHN is also acknowledged as crucial, necessitating rational relationships within their families. To facilitate integration, teachers should be prepared for both integrated and inclusive education, and an accessible environment plays a significant role. However, the paper acknowledges that the integration process can be complicated due to various factors, and it stresses the importance of a prepared society to successfully manage the inclusion of people with special needs. The paper serves as a concise and informative exploration of best practices for creating an inclusive educational environment for children with special health needs, based on a literature review and a reflexive approach.

Mentalization and Its Use in Schools
Authors: Nišponská Magda
Published: August 2023

Th is article outlines the current state of theoretical knowledge about mentalization, which appears to be essential for eff ective practice in the teaching profession. Mentalization is the capacity to understand and make sense of our own and others' actions by recognising and giving meaning to intentional mental states, including needs, thoughts, feelings, beliefs, and motivations. It is the understanding of the background of the behaviour – the understanding of the mental states that have led to a certain behaviour. Thanks to mentalization theory, we are now able to think and discuss in more detail what happens between and within people as they interact in diff erent social contexts such as schools. Th ese skills are useful for teachers as they work with children, whose metalizing skills are still developing. At the same time, in their practice, teachers often encounter children who come to school with disruptive behaviours, insecure attachment styles, and negative internal working models of relationships that make the  healthy development of mentalizing skills diffi cult. Th is article highlights the importance of mentalization in educational contexts and provides a framework for interventions aimed at increasing mentalization skills among teachers, parents, and students. Empirical evidence has shown that the implementation of mentalization-based programmes in schools can lead to signifi cant improvements in teacherresilience, as well as a reduction of aggressive behaviour among students and an improvement of their academic performance.

Published: August 2023

Human beings are important asset whose services are germane if an organization is to achieve high level of productivity hence this study investigated the relationship between organizational culture, staff welfare and job involvement among university employees in Ogun State. A survey research design was adopted and simple random sampling technique was employed to select 345 employees that participated in the study. A self-structured questionnaire with Cronbach alpha of r = 0.820 tagged “organizational culture, staff welfare and job involvement scale” was administered to elicit information from the participants. Pearson Product Moment Correlation analysis was used to test the stated hypotheses at 0.05 level of significance. Findings from the study revealed significant negative relationship between organizational culture and job involvement (r = -.122, p < .05), no significant relationship between staff welfare and job involvement (r = -.102, p > .05), and significant relationship between organizational culture and staff welfare (r = .804, p < .05). Based on the findings, the researchers, concluded that the major factors that could improve the employee job involvement in every organization are organizational culture and staff welfare, hence, it was recommended that university management should review their policies on organizational culture to make it employee accommodating while effort should be made to ensure that policies on staff welfare should be reviewed consistently to meet the personal needs of the workers.
Effective and Efficient Route Planning Using Historical Trajectories on Road Networks
Authors: Tian Wei , Shi Jieming , Luo Siqiang , Li Hui , Xie Xike , Zou Yuanhang
Published: August 2023

We study route planning that utilizes historical trajectories to predict a realistic route from a source to a destination on a road network at given departure time. Route planning is a fundamental task in many location-based services. It is challenging to capture latent patterns implied by complex trajectory data for accurate route planning. Recent studies mainly resort to deep learning techniques that incur immense computational costs, especially on massive data, while their effectiveness are complicated to interpret.

This paper proposes DRPK, an effective and efficient route planning method that achieves state-of-the-art performance via a series of novel algorithmic designs. In brief, observing that a route planning query (RPQ) with closer source and destination is easier to be accurately predicted, we fulfill a promising idea in DRPK to first detect the key segment of an RPQ by a classification model KSD, in order to split the RPQ into shorter RPQs, and then handle the shorter RPQs by a destination-driven route planning procedure DRP. Both KSD and DRP modules rely on a directed association (DA) indicator, which captures the dependencies between road segments from historical trajectories in a surprisingly intuitive but effective way. Leveraging the DA indicator, we develop a set of well-thought-out key segment concepts that holistically consider historical trajectories and RPQs. KSD is powered by effective encoders to detect high-quality key segments, without inspecting all segments in a road network for efficiency. We conduct extensive experiments on 5 large-scale datasets. DRPK consistently achieves the highest effectiveness, often with a significant margin over existing methods, while being much faster to train. Moreover, DRPK is efficient to handle thousands of online RPQs in a second,e.g., 2768 RPQs per second on a PT dataset,i.e., 0.36 milliseconds per RPQ.
The Composable Data Management System Manifesto

Published: August 2023

The requirement for specialization in data management systems has evolved faster than our software development practices. After decades of organic growth, this situation has created a siloed landscape composed of hundreds of products developed and maintained as monoliths, with limited reuse between systems. This fragmentation has resulted in developers often reinventing the wheel, increased maintenance costs, and slowed down innovation. It has also affected the end users, who are often required to learn the idiosyncrasies of dozens of incompatible SQL and non-SQL API dialects, and settle for systems with incomplete functionality and inconsistent semantics. In this vision paper, considering the recent popularity of open source projects aimed at standardizing different aspects of the data stack, we advocate for a paradigm shift in how data management systems are designed. We believe that by decomposing these into a modular stack of reusable components, development can be streamlined while creating a more consistent experience for users. Towards that goal, we describe the state-of-the-art, principal open source technologies, and highlight open questions and areas where additional research is needed. We hope this work will foster collaboration, motivate further research, and promote a more composable future for data management.

Published: August 2023

Die physikalischen Eigenschaften pneumatischer Antriebe ermöglichen den Bau von sicheren, leichten und intuitiv bedienbaren Robotern, deren Regelung jedoch herausfordernd ist. Gründe dafür sind die Dynamik der Pneumatik und nichtlineare Reibung mit Unsicherheiten, die ohne abtriebsseitige Momentensensorik unbekannt ist. In dieser Arbeit wird die nichtlineare modellbasierte Trajektorienfolgeregelung eines Roboters mit sechs pneumatischen Drehgelenken vorgestellt. Sie umfasst die Mechanik und Pneumatik sowie, im Gegensatz zum Stand der Technik, deren Verkopplung in einem zentralen Regler. Ausgehend vom dynamischen Modell des Gesamtsystems wird der Regler mittels Feedback-Linearisierung, einem Sonderfall der differentiellen Flachheit, hergeleitet. Die Regelung wird experimentell validiert und anhand der Messungen werden praktische Auswirkungen ihrer Struktur aufgezeigt.

The purpose of this research is to examine how “mother fans” impact on the existing patterns of parasocial relationships between fans and idols and to gain deeper insights into the motivations underlying the purchase of idol dolls. Additionally, by including the experiences and perspectives of male idol fans, the research seeks to broaden the understanding of fan behavior and enhance comprehension of the motivations driving idol-doll consumption.

Design/methodology/approach

Taking idol-doll buyers as research objects, this research conducted textual analysis and in-depth interviews to explore fans’ motivations for purchasing idol dolls.

Findings

Idol doll purchases are driven by emotional attachment, particularly among mother fans who seek to establish a sense of control and maintain a mother–child relationship. Additionally, buying idol dolls can also serve as a disguise for girlfriend fans to cover up their romantic fantasies about their idols. Moreover, idol dolls serve as semiotic identifiers, attracting like-minded fans and gaining community recognition. It should be noted that male idol fans, who are considered deviant from the masculine normative, face scrutiny in female-dominated communities, needing further proof of authenticity.

Practical implications

This research promotes understanding the motivations behind idol-doll purchases and can assist marketers in catering to the emotional needs of fans, particularly mother fans, by designing and marketing dolls that resonate with their desired sense of attachment.

Social implications

By recognizing and emphasizing the positive aspects of fan activities, this study contributes to the ongoing process of de-demonization and normalization of fandom. Additionally, this research also seeks to contribute to a more comprehensive understanding of the struggles and emotional needs of the Chinese young generation.

Originality/value

This study explores the under-researched mother-fan group’s emotional needs and their motivations of purchasing idol-dolls. It also acknowledges the distinct perspectives and experiences of male idol fans, providing a fresh and unique viewpoint on idol-doll consumption.
The group behaviour modelling of workers in the labor market
Authors: Shananin Alexander , Trusov Nikolai
Published: August 2023

We describe the mathematical modelling of the group behaviour of workers in the labor market. The worker receives the salary and seeks to improve his qualifications in order to receive higher wages. The worker enlarges his qualification by the investments in human capital. At a random moment of time, a vacancy appears that provides a jump in the worker’s salary. The mathematical model of the worker’s behaviour in the labor market is presented as an optimal control problem on an infinite time horizon. The paper presents the derivation of the Kolmogorov–Fokker–Planck equation for the Lévy process, which describes the behaviour of a large amount of workers within a social layer. The numerical solution of the Kolmogorov–Fokker–Planck equation and the calculation results are presented.
Pressure-correction projection method for modelling the incompressible fluid flow in porous media
Authors: Terekhov Kirill M.
Published: August 2023

This work is dedicated to the pressure-correction projection method for the volume-averaged Navier–Stokes system for porous media. A set of parameters controlling the presence of inertia and viscosity is introduced into the system. Switching parameters allows us to reduce the system to either the Brinkman system or the Darcy equation. Considering the jump in the parameters between mesh cells allows capturing the contact of media of different types, such as free-flow and porous media flow. We apply Chorin’s projection method to decouple the system. The splitting of the system yields a momentum conservation equation and an anisotropic pressure correction equation. We propose a combination of collocated finite-volume methods to solve the problem.
José María Morelos, Brownness, and the Visibility of Race in Nineteenth-Century Mexico
Authors: Jolly Jennifer
Published: August 2023

Independence hero José María Morelos y Pavón has been described racially as criollo, mestizo, Indigenous, mulato, and moreno, and scholars have long turned to his portraits to support claims made about his racial identity. However, the ambiguity of his social status during life and in his portraits has allowed scholars to project and reaffirm racial thinking rather than challenge its assumptions. Departing from this perspective, this essay examines his representation in text and image as a means of excavating the changing racial ideologies of nineteenth-century Mexico and the visual technologies that supported them. During Morelos’s lifetime, caste (lineage) remained the most significant signifier of status; however, emerging ideas regarding physiognomy, empiricism, and the bodily manifestation of racial character enabled competing assertions about Morelos’s race by midcentury. In the later nineteenth century, ethnohistorical notions of race began to emerge, allowing race to serve as an allegory of Mexico’s body politic. In this final phase, the ideology of Brownness emerged as a foil to mestizaje: a national body politic that created space for mixtures inclusive of Afro-Mexicans.
