Published: December 2023

Tractors are technological energy means used for general mechanization and automation of agricultural production, as well as for the transportation of finished raw materials. Tractors of traction class 8 must have high productivity and efficiency, in order to achieve the best results, in the shortest agrotechnical time.
The need for the development of tractor designs of the 8th traction class is explained by current trends in the development of agriculture. The increase in the area of agricultural land sets manufacturers the task of increasing the speed of tillage, which entails an increase in the power and ergonomics of tractors.
The necessary traction and layout characteristics of energy-saturated tractors of traction class 8 allow the implementation of articulated frames. The main task of the design is the development of a articulated frame with a cab rotation mechanism that will be able to fulfill the requirements for modern tractors of the 8th traction class.
Purpose. Investigation of the forces of resistance to rotation of the articulated frame and the occurrence of a favorable moment for turning the cab using a model in the MATLAB Simulink environment.
Methodology. Methods of mathematical modeling and analysis were used in the article.
Results. The parameters showing the necessary forces for the rotation of the articulated frame and the occurrence of a favorable moment for turning the cab are obtained.
Practical implications. The results obtained can be applied in the design of a tractor on a articulated frame with a cab rotation mechanism.

Aim of the studyThe COVID-19 pandemic has adversely affected the mental health of most populations and communities. This study sought to investigate the impact of COVID-19 on the likelihood of engaging in self-harm behaviors in a high-risk group.Subject or material and methodsParticipants (N = 659) were recruited to a multilingual depression/suicide screener. Counts of self-harm behaviors with intent to die, with ambivalent intent, and with no intent to die were examined in two time periods – mid-COVID-19 (March 15 to July 15 of 2021) and pre-COVID-19 (March 15 to July 15 periods of 2018-9).ResultsRegarding self-harm behaviors with the intent to die, pre-COVID-19, men were less likely to self-harm than women, whereas mid-COVID-19, the rates of these behaviors were similar for both genders and higher than pre-COVID-19. Regarding self-harm behaviors with ambivalent intent, a 3-way (cohort*gender*age group) interaction was noted, with younger men reporting fewer behaviors mid-COVID-19 compared to pre-COVID-19 and other men – more such behaviors; for women, these behaviors increased somewhat regardless of age group.DiscussionThe COVID-19 pandemic may have altered the pattern and likelihood of engaging in self-harm behaviors. The effect of COVID-19 on these behaviors may be different for men and women, depending on their age and the type of behavior.ConclusionsProviders should be mindful of the potential of self-harming in the pandemic era, especially among those with existing risk factors.

Published: December 2023

Aim of the studyFibromyalgia Syndrome (FM) is a chronic syndrome primarily characterized by widespread musculoskeletal pain. Although its aetiology is not fully understood, complex interactions between biological, genetic and various psycho-sociological factors are thought to be effective in the onset and maintenance of FM.Subject or material and methodsIn this study, we aimed to examine social cognitive and attachment profiles of FM patients. Methods: 41 women with FM and 44 healthy women matched for education and age were included in the study. There was no significant difference in sociodemographic parameters between patient and control groups. The participants were recruited from a University Hospital in Istanbul. Sociodemographic data were questioned in both groups while FM group was also administered Fibromyalgia Impact Questionnaire to determine disease severity. In order to evaluate social cognition profiles of the participants, Reading Mind in the Eyes Test, Empathy Quotient and Experiences in Close Relationships-Revised were conducted.ResultsFM patients did not differ significantly from control subjects by means of Reading Mind in the Eyes Test and Empathy Quotient scores (p= 0.33). Although no significant difference found between groups in means of attachment anxiety (p= 0.92), Fibromyalgia patients were found to have more avoidant attachment style than control group (p= 0.01).DiscussionFM patients may have no social cognition impairments, especially in lack of any psychiatric comorbidities. Moreover, these patients may suffer from avoidant type of insecure attachment and this attachment style may affect social support seeking behaviour of these patients.ConclusionsAttachment based interventions may be important in the treatment of FM Syndrome
Linking disgust and misophonia: The role of mental contamination
Authors: Barahmand Usha 
Published: December 2023

Aim of the studyIn the current study, the authors sought to examine whether the link between moral and sexual disgust and misophonia is mediated by mental contamination.Subject or material and methodsAn internationally diverse sample of 283 adults (193 females, 76 males, and 14 non-binary individuals) ranging in age from 18 to 60 years old was recruited from online social media platforms and survey recruitment sites. The sample completed an online battery of scales that consisted of the New York Misophonia Scale, State Metal Contamination Scale, and the Three-Domain Disgust Scale. The hypotheses were evaluated using a series of mediations. performed using the PROCESS add-on in SPSS.ResultsCorrelations were found between emotional and aggressive-avoidant reactions in misophonia, mental contamination, pathogen disgust, and sexual disgust. Moral disgust and non-aggressive reactions in misophonia failed to correlate significantly with any of the other constructs. Sexual disgust had direct and indirect effects while pathogen disgust had only direct effects on aspects of misophonia.DiscussionThese findings partially support our hypothesis that mental contamination mediates the link between disgust propensity and misophonia while also confirming that pathogen-based disgust is not associated with mental contamination.ConclusionsFindings imply that misophonia is distinct from obsessive-compulsive disorder. Further research into the conceptualization of moral disgust is warranted.

Published: December 2023

El presente trabajo se propone examinar las propiedades psicométricas de la adaptación al contexto argentino de la escala de fear of missing out (FoMO, miedo a perderse algo) en una muestra compuesta por residentes del Área Metropolitana de Buenos Aires (amba) (Argentina). La escala permite medir un único factor que establece el grado en que las personas se encuentran pendientes de las actividades ajenas en comparación con las propias. Del estudio participaron 416 personas con edades entre 18 y 66 años (M = 28.82) y de diferentes géneros (hombres = 25 %; mujeres = 75 %). Los análisis confirmatorios arrojaron valores superiores a 0.90 para los índices ifi, nnfi y cfi, y para el rmsea, valores inferiores a 0.08. La consistencia interna evaluada a partir de los estadísticos alfa ordinal y omega de McDonald fue aceptable (α = 0.77; ω = 0.99). La evidencia de validez externa de la escala demostró asociaciones significativas con la escala de autoestima de Rosenberg (rses), de manera consistente con estudios previos.

La atención es definida como un constructo multidimensional, encargado de regular sobre qué estímulos se dirigirán los recursos perceptivos, filtrando información irrelevante con el fin de favorecer la retención de información durante un período antes de actuar sobre ella. La evaluación computarizada de la atención ha ido cobrando relevancia tanto en la investigación como en las prácticas del quehacer profesional. Los objetivos de este estudio fueron: 1) analizar la consistencia interna y la validez concurrente del Test de Atención Infantil 6.0 (tai), versión computarizada; y 2) obtener los valores de referencia preliminares para cada subtest del tai. Los estudios de confiabilidad y validez del tai corresponden a una muestra de 122 escolares de Mendoza (Argentina). Al analizar la consistencia interna se obtuvieron valores satisfactorios para cada uno de los subtests (Test 1, kr 20 = 0.78; Test 2, kr 20 =0.74; Test 3, kr 20 = 0.73). Se obtuvieron valores satisfactorios al explorar la estabilidad del instrumento. Al analizar la validez concurrente, los resultados indicaron correlaciones positivas moderadas y significativas (p <0.01) entre el test Caras-R y los subtests 1 y 2 del tai, utilizado para evaluar desempeño atencional. Se observaron asociaciones positivas significativas (p <0.01) entre el subtest 3 del tai y el Test de Bloques de Corsi, usado para evaluar memoria de trabajo visoespacial. Estos resultados señalan que el tai, instrumento desarrollado para evaluar la atención y memoria de trabajo visuoespacial en escolares, presenta indicadores adecuados de validez y confiabilidad.

Published: December 2023

Introduction Staging of oesophagogastric (OG) cancers usually involves endoscopy (OGD), and separate visits for contrast enhanced computed tomography (CeCT) and positron emission tomography (PET/CT). At the height of the COVID-19 pandemic, some of our patients underwent single-visit combined staging with PET/CeCT. We compare this novel pathway with standard separate imaging in time to completion of staging, to start of treatment, and cost. Methods We identified all patients discussed at our OG multidisciplinary team (MDT) meeting in 2020. Clinical records revealed dates of investigations and treatments. Data were tabulated in Excel, with statistical analysis in SPSS. All patients followed the same MDT process and image reviewing criteria. Costs were compared using prices supplied by finance departments. Results A total of 211 new patients were discussed at our MDT in 2020. Of these, 48 patients had combined PET/CeCT staging, and 68 had separate scans. Median time (interquartile range) in days from OGD to final imaging was 9 (6–23) for the combined group versus 21 (16–28) for the separate group (p≤0.001). Median time (days) from OGD to treatment start was 37 (29–52) for combined versus 55 (40–71) for separate (p≤0.001). No combined scans were of insufficient diagnostic quality for the MDT. PET/CeCT had a potential cost saving of £113 per patient. Conclusions PET/CeCT allows accurate radiological staging of OG cancers with a single scan. Patients completed staging and started treatment faster, with a potential saving of £10,509 in one year. PET/CeCT has become standard staging at our trust, and we aim to incorporate radiotherapy planning images too.

Published: December 2023

Background Patients with an intestinal emergency who do not have surgery are poorly characterised. This study used electronic healthcare records to provide a rapid insight into the number of patients admitted with an intestinal emergency and compare short-term outcomes for non-operative and operative management. Methods A single-centre retrospective cohort study was conducted at a tertiary NHS hospital (from 1 December 2013 to 31 January 2020). Patients were identified using diagnosis codes for intestinal emergencies, based on the inclusion criteria for the National Emergency Laparotomy Audit. Relevant data were extracted from electronic healthcare records (n=3,997). Results Nearly half of patients admitted with an intestinal emergency received nonoperative management (43.7%). Of those who underwent surgery, 63.7% were started laparoscopically. The non-operative group had a shorter hospital stay (median: 5.4 days vs 8.2 days [started laparoscopically] or 16.8 days [started open]) and fewer unintended intensive care admissions than the surgical group (2.4% vs 8.7% [started laparoscopically] 21.1% [started open]). However, 30-day mortality for non-operative treatment was double that for surgery (22.4% vs 10.1%). The 30-day mortality rate was found to be even higher for non-operative management (50.3%) compared with surgery (19.5%) in a sub-analysis of patients with admission National Early Warning Score ≥4 (n=683). Conclusion The proportion of patients with intestinal emergencies who do not have surgery is greater than expected, and it appears that many respond well to non-operative treatment. However, 30-day mortality for non-operative management was high, and the low number of admissions to intensive care suggests that major invasive treatment was not appropriate for most in this group.
Secure key generation and distribution scheme based on historical fiber channel state information with LSTM
Authors: Wang Danyang , Wang Hongxiang , Ji Yuefeng 
Published: December 2023

In this paper, a scheme to realize unclonable physical-layer security key generation and distribution (PL-SKGD) based on historical fiber channel state information (HFCSI) is proposed. PL-SKGD schemes based on channel characteristics for enhancing the physical-layer security of optical networks have been proposed in recent years. However, there are potential disadvantages in these schemes, such as 1) low key generation rate (KGR): the slow frequency of the analog waveform change of the channel characteristic leading to low KGR; 2) incompatibility with existing infrastructure: active scrambling to increase the frequency of channel characteristic changes, or tracking changes of channel characteristics requires additional devices; 3) easy to be cloned: all of the optical channel state information is reflected in the signal transmitted inside the fiber, which makes it easy to reproduce by illegal eavesdropper through features analysis and other methods. In order to solve the above problems, a PL-SKGD scheme is designed which uses the chain structure composed of long short-term memory neural network (LSTM-NN) units to learn and store the unique mapping relationship between historical channel time series and provides unclonability based on the fundamental fact that the eavesdropper Eve can never obtain the full HFCSI. The simulation conducted in a quadrature phase shift keying point-to-point optical link system verified successfully that KGR = 0.82 Gbit/s error-free SKGD. The loss function of LSTM-NN drops sharply in the early stages of training and remains a small value. The security of the SKGD system is analyzed, which effectively improves the unclonability of the system. Finally, it is verified that the optimal fiber channel length for error-free SKGD of the proposed scheme is 150 km considering the error correction capability of information reconciliation and weighing key sequence error rate and valid bit generation rate.
An Investigation of the Altman Z-Score Measure and Return on Equity (ROE) of Firms in the Airline Industry
Authors: Willey Thomas , Edwards Susan , Bhagwat Yatin 
Published: December 2023

This research measures the relationship between the Altman Z-Score, a measure of a firm’s financial health, and the Return on Equity (ROE), a measure of a firm’s profitability for a sample of airline companies. The period of the study covers 2014 to 2022 and uses linear regression to examine the relationship between ROE (dependent variable) and the Z-Score (independent variable). Our data set contains sixty-five (65) airline firms traded on twenty-eight (28) stock exchanges. Our initial hypothesis is that a positive and statistically significant relationship exists between the two variables over the examined period. Further research will look at the relationship in other sectors of the markets.
Planning, Monitoring and Evaluation Arrangements in Zambia’s Public Sector: Shifting Sands or a Solid Rock?

Published: December 2023

The paper asks a prime question: Are Zambia’s Planning, Monitoring and Evaluation arrangements Shifting Sands or a Solid Rock? The country, through its policy and legislative instruments has in the recent years articulated and adopted clear frameworks for national planning, budgeting, monitoring and evaluation of public interventions. However, despite these efforts, there still remain a lot of critical questions unanswered. Do the current planning, budgeting, monitoring and evaluation arrangements address Zambia’s development agenda? Are different development plans at national, line ministry, provincial and district level aligned towards a streamlined effort to alleviate the country out of abject poverty? Is there evidence that national annual budgets are directly derived from programmes and activities from various development plans at line ministry, provincial and district levels? Can we track programmes in national development plans (NDPs) within annual budgets? In the literature reviewed, answers to these questions are mixed. While other questions are in the affirmative, many of them have weak evidence. There are strong indications that Zambia’s frameworks for planning, budgeting, monitoring and evaluation would require restructuring to remove redundancies, repetitions and unnecessary bureaucracies. Even when the policies and legislation are clear on what plan needed to be developed and implemented at various levels, in many cases, these remain in draft forever or worse off non-existent. These challenges are more prominent at decentralised levels where plans and M&E practices are weak and fragmented a great deal. Many plans have been prescribed at provincial and district level, yet they are not actualised. They cause staff fatigue on one hand while crowding-out development evidence on the other hand. Therefore, it is recommended that a detailed study is undertaken, one that take the form of a readiness assessment to map out what plans, M&E arrangements and budget frameworks are working well, not working well and reasons why. Such a report will be a good starting point to reform the planning, budgeting, monitoring and evaluation architecture for Zambia. A focused approach will be sound and will lead to a predictable and sustainable development agenda for the country.
