Background:
Periodontitis is the most common type of periodontal condition, primarily affecting middle-aged people and resulting in tooth loss; when combined with diabetes, it becomes a debilitating condition. The aim of this study is to compare the residual periodontal ligament length in periodontitis patients with and without diabetes.

Materials and Methods:
The cross-sectional observational study was conducted in the department of periodontics over 5 months. The patients in the study were divided into two groups. Group 1 comprised patients with periodontitis without type 2 diabetes and Group 2 comprised patients with periodontitis with type 2 diabetes. A total of 100 teeth 50 from each group were collected. The teeth were stained, and the Residual Periodontal Ligament (RPL) of all tooth aspects and surfaces to a total of 544 were measured. Two points were identified for measuring the RPL. The first point was from the apex of the tooth and the second point was the highest marking of the stain. The length from these two points was recorded as the RPL. Following which, means from Groups 1 and 2 were calculated to determine the rate of destruction. The average of the values for each tooth was calculated to determine the percentage of RPL in each tooth and surface. The Mann–Whitney test was used to compare the RPL of the teeth surfaces and Group 1 and Group 2 and P < 0.05 was considered statistically significant.

Results:
The RPL was higher in nondiabetic patients, with a mean value of 23.66 mm, when compared to diabetic patients, with a mean RPL of 17.05 mm, implying that diabetic patients showed greater periodontal destruction. Buccal tooth surfaces displayed a mean RPL of 4.24 mm and 6.00 mm, lingual/palatal tooth surfaces with 4.02 mm and 5.91 mm, mesial tooth surfaces with 3.82 mm and 5.64 mm, and distal tooth surfaces showed 4.14 mm and 5.67 mm (diabetic and nondiabetic, respectively) with (P < 0.001) found to be statistically significant.

Conclusion:
This study observed that the destruction rate of the periodontal ligament was higher in diabetic teeth than in nondiabetic teeth, implying that patients with metabolic diseases such as type 2 diabetes influence the response of periodontal tissues to periodontitis and that hyperglycemia impacts the periodontal ligament either directly or indirectly.
K-stability for varieties with a big anticanonical class
Authors: Xu Chenyang 
Published: September 2023

We extend the algebraic K-stability theory to projective klt pairs with a big anticanonical class. While in general such a pair could behave pathologically, it is observed in this note that K-semistability condition will force them to have a klt anticanonical model, whose stability property is the same as the original pair.Comment: 9 pages, Final version

Central Asian Trade Caravan Masters in the First Half of the 19th century: Social and Labor Aspect
Authors: Abdrakhmanov Konstantin A. 
Published: September 2023

The study highlights the specifics of the professional activities of caravan masters from the khanates of Central Asia who controlled the movement of caravans in Russian-Asian trade in the first half of the 19th century. The article examines the social status of the caravan masters, defines their authority and main duties during the journey to trading locations, analyzes the features of interpersonal interaction between the leaders and other caravan members, and focuses on the moral and psychological qualities of the caravan leader.
From the moment the caravan set out on a long and dangerous journey through the steppe and desert areas, the caravan master, officially approved by the government of a Central Asian khanate, gained full control over the process of movement. Taking full responsibility for the life and health of the caravan personnel, as well as the safety of the goods, the leader chose the optimal route, determined the locations for stops, controlled the duration of rest, and monitored provisions consumption.
The study demonstrates that the official duties of the caravan leader in the unique logistical setting of a merchant caravan were accompanied by various tasks, the effective solution of which depended on the leader’s business mentality and special skills. The archival materials used in this work are being introduced into scientific circulation for the first time.

Published: September 2023

Background and aim: Physical inactivity is a preventable epidemic in both developed and developing countries. This study aims to examine the factors related to the perception of exercise benefits and barriers among adolescents. Material and methods: The cross-sectional study included 3405 adolescents in 15 public high schools in Ankara, Turkiye. The sample size was calculated using a cluster sampling method. The data collection form consisted of three sections. The first section included the socio-demographic characteristics of participants and the second section contained sedentary lifestyle characteristics of participants. The first two sections were prepared based on the literature by the researcher. The third section of the data collection form included the Exercise Benefits and Barriers Scale which was a valid and reliable instrument for the Turkish population. Spearman’s correlation test, Chi-square test, Mann Whitney U test, and Kruskal Wallis test were used for statistical analysis. Cronbach’s α was calculated to determine the internal reliability of the scale.
Results and conclusion: In this study the mean age was 16.54 (1.09) years and 57% (n=1940) of the participants were female. More than half of the participants reported insufficient physical activity (56%) and irregular exercise (62.1%). The total Exercise Benefits and Barriers Scale score was 92.79 (13.22) and Cronbach α was 0.84 for the total of the scale. In this study, some factors such as sex (z=8.870; p=0.001), grade (z=20.37; p=0.001), physical activity (z=12.093; p=0.001), duration of sitting (z=3.555; p=0.001) were associated with perceptions of exercise benefits and barriers. A professional nursing approach can maintain lifelong activity and exercise by improving professional nursing interventions and perceptions of exercise benefits and effectively managing the relevant barriers and risks.
In the Castle of My Skin: (Re)Inscribing an African “Feminist” Identity in Changes and Faceless
Authors: Danquah Grace 
Published: September 2023

ABSTRACT
The analysis of African feminism in literary works is now a well-established area in literature. Most of the research on Changes and Faceless focuses on a thematic or stylistic study of the text. An often-underexplored area is how these two authors utilize the element of characterization to (re)inscribe the boundaries of African-centered feminist identities. To fill this gap, this article comparatively analyses the portrayal of “feminist” identity in Aidoo’s Changes (1994) and Darko’s Faceless (2003). The article reaffirms the stance assumed by Nigerian theorists like Nnaemeka, Ogundipe-Leslie, and Akachi that the feminist in Africa is accommodative, compromising, and collaborative. Using negofeminism (No ego feminism) theory as an analytical framework, this article reveals that in Faceless, the female characters who survive and thrive are those who live out the very tenets of the theory. In Changes, Esi is isolated in the end because she chose individualism over communalism. Consequently, this article extends the scholarship on literary representation of African feminism in women-authored novels. This validates the conclusion that African feminism as portrayed by Aidoo and Darko is truly representative of indigenous societies.
Pass-through of rising production costs to the selling prices of non-financial corporations in 2022
Authors: Blanco Escolar Roberto , Khametshin Dmitry , Menéndez Pujadas Álvaro , Mulino Ríos Maristela 
Published: September 2023

Rationale
The surge in energy and other commodity prices in 2021 H2 and a significant part of 2022 has led to firms’ costs increasing considerably. This article analyses how this rise in costs has been passed through to selling prices and what impact it has had on firms’ output, wages, employment and unit labour costs.
Takeaways
•On average, firms passed through a significant proportion of production cost increases to selling prices in 2022, albeit with a high degree of heterogeneity across sectors.
•In sectors that have historically seen more rigid pricing (proxied by lower price volatility), pass-through of rising costs to selling prices has been slower.
•Rising input prices directly cause selling prices and unit labour costs to grow. The latter is a consequence of the negative effect on labour productivity, owing to the adverse impact on output and the lack of an impact on personnel costs.
•In any case, these direct effects, which are stronger in the sectors most exposed to this shock, do not account for the indirect (general equilibrium) effects that influence all sectors.

Published: September 2023

School managers have always been on the forefront of the administration of education system since they are the active agents who lead their schools towards wider goals of improving access and quality of education. The purpose of the paper is to give an assessment and evaluation of the concept of innovation by school managers and leaders in the schools. This paper explores impact of innovation and the role of school managers in creating and maintaining an innovative culture and academic performance in selected public schools of the Cofimvaba Education District, which has become synonymous with declining pass rates post-1994.A qualitative research approach was used where existing literature collected, collated and thematically analysed. This paper is novel because it seeks to contribute to the current debate in the literature of educational innovation. The scientific novelty of the article also consists of a conducted large-scale study describing the author's theoretical and practical prerequisites as a former school manager and evidence presented in the research empiricism. The findings of the paper indicated that the school principals are not empowered or willing enough to catalyse the creation and sustaining of innovative cultures in schools. Furthermore, the novelty of the results shows the innovation effects in the high schools and the criteria that school managers employ to get results. Other findings include evidence policy gaps on what is innovation and who must do what in schools which affects the efficacy of school managers. The paper also established that the bureaucratisation of the education sector has done nothing by crippled school managers’ ability to innovate by school managers. Furthermore, the paper recommends strategies on how school managers can become that active catalyst that they should be, to drive innovation include in-service training and setting minimum benchmarks for school managers eligibility. Also, policy interventions such as 4th industrial revolution aligned innovation regulations, exchange of ideas with countries which successful school innovation formulating a sanction model of non-performers, towards improving access and quality of education in the Cofimvaba Education District.
