Authors: Tymowski Michał
Published: December 2023

The aim of the author of the article is to examine the role of the week and the related dimension of serfdom (corvée) in the treasury system of Rwanda in the second half of the 19th century and the beginning of the twentieth century. The author discusses the current state of research and various opinions on the credibility of written and oral sources relating to this issue. Subsequently he quotes and analyzes a hitherto unknown source regarding the functioning of the week and serfdom, i.e. fragments of Jan Czekanowski's manuscript diary from field research in Central Africa, including Rwanda, in the years 1907–1909. Czekanowski not only confirms the existence of the week – corvée system in the central provinces of Rwanda and draws attention to the conflicts related to its operation, but also describes the methods of legitimizing this form of duty used by the ruling group in Rwanda.

The paper investigates the schemes of frequency synchronization of signal reception of satellite communication system based on DVB-S2 standard with different combinations of coarse and fine frequency synchronization algorithms, namely, the following pairs of algorithms are considered: «Edge band» and «Delay & Multiply», «Delay & Multiply» and «L&R», «Edge band» and «L&R», where the first algorithm in each pair performs the task of coarse and the second algorithm performs the task of fine frequency synchronization. The accuracy of the investigated frequency synchronization schemes is evaluated using the Root Mean Square Error (RMSE) metric of frequency offset estimation in the channel. In addition, one of the performance metrics of the algorithm is the estimation of synchronization time. The frequency shift in the signal transmission channel is set constant and equal to 20% of the signal bandwidth. Using combinations of Non-Data-Aided (blind) algorithms for coarse frequency shift estimation and Data-Aided algorithms for fine frequency synchronization, the synchronization time can be reduced by almost a factor of 2, while maintaining high accuracy of RMS estimation.
How Does Mentoring Affect Self-Efficacy?: An Investigation on Turkish Principals
Authors: MAVİ Duran , TOPALOĞLU Hakan , USLU ÇETİN Oya , TUTİ Gamze
Published: December 2023

Mentoring is one of the professional development tools supporting school principals. Thanks to mentoring, principals can overcome the problems they confront and meet the expectations of different stakeholders. Thus, principals are able to perform more effectively in schools. Mentoring has become a formal process for principals in various countries for a long time. Moreover, several researchers from different countries focus on the various impacts of mentoring on principals. One of these is the self-efficacy of principals. Mentoring has the potential to enhance the principals' self-efficacy. However, it is difficult to note that mentoring and its influence on principals' self-efficacy have been analyzed thoroughly. In this context, this phenomenological study aims to overcome the current inadequacy. The study data was collected based on criterion and snowball sampling from eight principals working in Kahramanmaraş province. MAXQDA 2020 was utilized for data analysis. The results revealed that mentoring plays a critical role in the self-efficacy beliefs of principals. In other words, it develops principals' managerial, instructional, and ethical competencies. This finding significantly contributes to the literature on principals' professional development, professional learning, and self-efficacy. Several suggestions have been offered for policymakers and researchers about the formalization of mentoring and the details of its implementation.
Ethnocentrism among consumers in selected central European countries
Authors: Řezanková Hana , Hinčica Vít , Macias Klaudia , Jakubová Dominika
Published: December 2023

By employing surveys, this paper aims to conduct a cross-national comparison of ethnocentric behaviour in three neighbouring countries in the Central European region. The level of ethnocentrism, expressed by a reduced CETSCALE, is measured and assessed using six demographic indicators and four products. Responses to the reduced CETSCALE show that Polish respondents are more ethnocentric than Czech and Slovak respondents and that Slovak respondents are more ethnocentric than Czech respondents. However, only the differences between Czechia and Slovakia, and between Czechia and Poland are statistically significant. The strongest level of ethnocentrism among Poles is also evident when analysing consumer opinions on the four selected products. As far as possible differences in the ethnocentric consumer behaviour of the population are concerned, the analysis revealed that age and permanent residence in the three selected countries are discriminating factors. The study is original in that it combines two levels of investigation and examines three neighbouring countries simultaneously.
Lightweight Composite Applications in the Structural Design of Quadricycles
Authors: ÇELİK Okan , TOPAÇ Mehmet Murat
Published: December 2023

Due to the increasing number of internal combustion engine vehicles, fossil fuel sources have decreased drastically in the last century. In addition, the concerns about global warming caused by vehicle emissions have led automotive manufacturers to search for new alternatives to transport. Quadricycles have started to be seen as future transport vehicles due to their smaller design and lower energy consumption when compared to conventional vehicles. Furthermore, they are also considered to prevent increasing traffic jams in metropolitan areas. The lightweight design of a quadricycle is crucial since its weight would affect energy consumption. On the other hand, because of their minimalistic design, crashworthiness is another factor that must be considered in the structural design of quadricycles for the safety of occupants in case of a collision. Composites are one of the most promising materials for manufacturing lightweight structures due to having a high strength-to-weight ratio compared to conventional metals. In this study, different body designs and optimizations of quadricycles are introduced. Comparisons are made between conventional metals and composite materials used in quadricycles in terms of weight and stiffness.
Reproductive Changes in the Population of the Republic of Croatia
Authors: Ileš Marija , Karačić Domagoj
Published: December 2023

Knowledge of demographic trends is the basis for policy making, both economic, social, health, etc., as well as population policy. The Republic of Croatia has been facing demographic problems for many years, mainly an increase in the elderly population with a simultaneous decrease in the reproductive base and the number of young people. Croatia is one of the countries in the post-transition stage of population characteristics, characterized by the transition of the total fertility rate from a low positive rate to a level that no longer ensures the renewal of generations, and the mortality rate, which is determined by increasing life expectancy. In the Republic of Croatia, fertility is measured by the periodic total fertility rate, which indicates the average expected number of live births that a woman of fertile age (15 to 49 years) would give birth to. The total fertility rate of 2.1 children is often cited in the literature and among the public as the numerical level of generational change, while the Republic of Croatia has recorded a total fertility rate below this level for decades, i.e., 1.48 (2020). Another important characteristic of the post-transition period is late childbearing. The age limit for marriage and readiness to have a first child is increasing. The average age of a mother at the birth of her first child increased from 23.5 years (1960) to 29 years (2020), which significantly shortens a woman's reproductive time. Due to numerous factors, the number of live births has decreased from 95,560 children in 1960 to 35,845 children in 2020, a decrease of 59,715 live births. The subject of this work is a study of the reproductive determinants of population development in the Republic of Croatia, focusing on the determination of the factors influencing fertility and the quantitative presentation of demographic indicators. The aim of this work is to find the cause of declining fertility. Therefore, this work analyzes the factors that influence fertility. Due to the resulting birth deficit, it is necessary to take measures to promote births. Therefore, in the concluding remarks, recommendations are given for improving the demographic situation in the Republic of Croatia in the context of promoting births and increasing fertility. Keywords: reproductive changes, fertility, Republic of Croatia, total fertility rate

Published: December 2023

Se desarrolla un estudio comparativo de los modelos de gestión de las metrópolis Morelia-Tarímbaro, en Michoacán, México, y La Serena-Coquimbo, en la región de Coquimbo, Chile. El objetivo es analizar los modelos de gobernanza, relacionándolos con el modo en que se produce la expansión urbana en estas ciudades y los efectos sociales y del espacio físico. Se aplica el método descriptivo que evidencia la escasa relación que existe entre el modo de expansión de la metrópolis y el proceso de gobernanza. Pese a que en ambos países existen múltiples actores e instrumentos, estos no logran resultados concretos y prácticos, debido a que se quedan en propuestas, o actúan de modo disperso, es decir, sin ser vinculante en los territorios. La conclusión abona en invertir el abordaje de la gobernanza, a partir de reconocer cuáles son los actuales modos urbanos imperantes y proponer acciones estratégicas que reviertan las problemáticas metropolitanas.

Published: December 2023

In recent times, nanoparticles have been used as raw ingredients for biofertilizers, mineral supplements in animal feed, and pharmaceuticals. Manganese plays a vital role in enhancing fish's growth and biological function. The present research work aimed to analyze the various quantities of manganese oxide nanoparticles on common carp growth and its haematological traits. Synthesized manganese oxide (Mn3O4) nanoparticles were illustrated using UV-visible Spectroscopy (UV-Vis), Scanning Electron Microscope (SEM), Energy Dispersive X–Ray Spectroscopy (EDAX), X–Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR). Six different feeds were prepared by incorporating different quantities of manganese oxide nanoparticles (Feed I (control-0mg), Feed II(3mg/100g), Feed III(6mg/100g), Feed IV(9mg/100g), Feed V(12mg/100g), and Feed VI(15mg/100g)) with common ingredients such as groundnut oil cake, fish meal, tapioca flour, and wheat flour. On the completion of 21 days, feed utilization and haematological characteristics of Common carp were assessed. The UV-Vis showed that manganese oxide nanoparticles exhibit strong adsorption peaks at 220nm. SEM image observed at the wavelength range from 9.22 nm to 9.35 nm. The size of the particles was in the 45-55 nm range. The EDAX spectrum recorded two peaks between 0.40 and 6 kev. The XRD graph shows that the diffraction peaks are indexed as 103, 004, 213, 204, 303, and 215. FT-IR spectrum measured at the wavelength range from 500-4000cm-1. Most of the growth parameters and haematological parameters were higher in feed III, containing 6mg of Manganese oxide nanoparticles. Therefore, results show that manganese oxide incorporated feed enhances the growth and haematological traits in common carp compared to control feed.

Published: December 2023

Mangrove forests are found on coastlines in tropical and subtropical areas. The mangrove tree looks strange because its roots are partially above water, making it look like it is standing. Mangrove forests are coastal forests and critical habitats that act as nurseries and protect coasts from erosion. Determining the current status of sustainable management of mangroves is very important as a basis for planning future policies. The purpose of this study was to review the current status of mangroves and analyze the sustainability value of the mangrove ecosystem sustainability in the Biringkassi mangrove area, Pangkep district, Indonesia. This study is descriptive with a quantitative approach to conducting an inventory of mangrove ecosystems, including biophysical, social, economic and institutional data. Analysis of the sustainability of mangrove management The sustainability of the mangrove ecosystem was analyzed using the Rapid Assessment Fisheries (RAPFISH) software with the Multidimensional Scaling Method (MDS) method. The four aspects assessed were ecological, economic, social and institutional. The results of the sustainability analysis from the four dimensions showed that the ecological and institutional aspects have a moderate state of sustainability, but the economic and social aspects have a less sustainable state. Multidimensional analysis showed less sustainable management. Leverage analysis of 24 multidimensional attributes revealed eight highly influential attributes that can lead to change in management if not implemented correctly. Meanwhile, the analysis results should be maintained for properties that achieve low leverage so that the management value does not decrease.

Authors: Bawa I Gusti Agung Gede , Irdhawati  , Putri Komang Triana
Published: December 2023

Reactive dyes such as Remazol Yellow FG are contaminants that are difficult to degrade in the environment. The adsorption method is an alternative to overcome this problem. Corn husk and eggshells can be adsorbents in adsorption. Corn husk contains an organic compound called cellulose, while eggshells have the main component of calcium carbonate. Corn husks and eggshells have the potential to be adsorbents with different characteristics. This research aimed to determine the optimum conditions for the combined adsorbent of corn husks and eggshells, which included composition comparison, contact time, pH, and application in dye waste. The interactions between Remazol Yellow FG dye in solution and combined adsorbent were conducted in batch method. Based on the research results, the optimum composition of corn husks and eggshells was 1:2, with an optimum contact time of 80 minutes at a pH of 2, resulting in an adsorption capacity of 0.559 mg/g, with an adsorption percentage of 33.95%. Adsorption of Remazol Yellow FG in sewage using combined adsorbents under optimal conditions obtained an adsorption capacity of 36.6579 mg/g with an adsorption percentage of 27.87%. The results demonstrate that the combined adsorbent of corn husks and eggshells is a potentially useful for removing Remazol Yellow FG dye from textile wastewater.
The Postsecondary Future Selves of Black and Latinx Boys: A Case for Cultivating More Expansive Supports in College-Going Schools
Authors: Carey Roderick L.
Published: December 2023

Black and Latinx adolescent boys from economically stratified communities face pervasive societal inequities and, therefore, deserve more responsive school supports to determine and actualize postsecondary pathways. For insights into how such students conceptualize their futures and their school’s role in facilitating this process, this ethnographic study investigated one urban school’s college-going culture and its impact on shaping what the author calls participants’ postsecondary future selves. This theoretical approach encompasses three domains: college (i.e., postsecondary education), career (i.e., post-college employment trajectory), and condition (i.e., expected financial stability, relational and familial prospects, future living arrangements, happiness, and joy). Implications suggest that college-going school practitioners widen supports so students can imagine and envision how college ambitions align with career and condition goals.

Authors: Shaymaa Saadoon Hashem
Published: December 2023

In this study, X-ray attenuation measurements for voltages (20, 25, 30, 35) KV using X-ray unit with copper X-ray tube were performed for the composites material that consist of epoxy as a matrix and titanium oxide as a reinforced at concentrations ( 4 and 6 Wt. %) which was prepared by hand- lay-up method by using mechanical mixer . The linear attenuation coefficient (μ) was obtained by linear equation of the graph representation output between the logarithm of absorption and the thickness of the samples where the slope of the graph represents the linear attenuation coefficient. The obtained results showed that the linear attenuation coefficient increased by increasing the weight percentage of titanium oxide and the highest value obtained at 6Wt .% . The inverse relation between the linear attenuation coefficients of the composite samples with the x-ray voltage was also concluded. The values of mean free path (λ), halve value layer (HVL) and tenth value layer (TVL) was calculated in this study, the results were shown that the values of λ, HVL, and TVL, for pure epoxy is greater than its values of the composite material with 4and 6 Wt. % of TiO2 at all values of voltages mentioned above. The results obtained showed the efficiency of the prepared composites in the X-ray absorption and attenuation, this efficiency is relatively variable depending on the ratio of the reinforced material TiO2 which demonstrating the great and a positive effect of it on the radiation shielding properties of the epoxy polymer.

The study was undertaken to investigate the effect of neem oil that extracted from Azadirachta indica tree against the larvae of Culiseta longiareolata (Macquarrt) mosquito in all larval instars.The larvae were exposed to different concentrations of neem oil (0.001%,0.01%,0.1%,0.5% and 1%) for 24h and 48h under laboratory conditions.Neem oil was more toxic against 1st.larval instar and reached 90% mortality at concentration of 1% for 48h while the responds of 2nd.,3rd. and 4th. Larval instars were(86.66%,46.66% and 43.33%), respectively. The statistical results of LC50% value have been shown of the larvae: 1st.,2nd.,3rd. and 4th.instars were (0.713%, 0.748%, 1.588% and 1.797%), respectively. While the LC90% were (1.120%,1.169%,7.599% and 9.516%) , respectively with confidance limits (95%) within 24h . The lethal concentration was increased with larval stage. In the same period the LC50% of the 4th. larval instar is 2.52 times the LC50% of the 1st.larval instar, also the LC 90% is equivalent 8.49 times the LC90% of the 1st.larval instar. In 48 h, the LC50% of the 4th. larval instar is 2.61 times the LC50% of the 1st.larval instar, also the LC 90% is equivalent 7.53 times the LC90% of the 1st.larval instar.The results of the statistical analysis(Gretl) showed a significant positive correlation with both levels (0.05 and 0.01) from significant between the mortality ratios of the larval stages and the concentrations used ,the peak was in the larvae of the first instar when the P-value = 0.0001.

Cultural evolvability and cognitive technologies
Authors: Charbonneau Mathieu
Published: December 2023

Cognitive technologies enhance and expand our problem-solving capabilities beyond what we can do on our own, unaided. This means that as new cognitive technologies are invented and used, and as these new technologies form traditions specific to those populations that harbor them, our species increases its cognitive capabilities through time. Human cognition is, in this sense, a historically moving target. Cognitive technologies also played and continue to play a role in the invention, development, and improvement of new technologies, including further, more empowering cognitive technologies. This means that as cognitive technologies are developed, they expand our inventive capabilities. This dynamic process generates a positive feedback loop, wherein earlier cognitive technologies enable the invention and advancement of more powerful cognitive technologies in an iterative, open-ended manner. In this paper, I argue that the process of cumulative cultural evolution is at pains of explaining the evolvability of human technologies, describe how cognitive technologies make us ever smarter at invention, and clarify how cognitive technologies enable a bootstrapping dynamic leading to evolvable, open-ended technological change.

Published: December 2023

The reviews in this special edition have presented a primer on the state of the literature for six different psychedelic compounds and their plausible role in medicine. In a common format underscoring strengths, weakness, opportunities, and threats (SWOT), this article addresses how psychedelic compounds fit into the broader healthcare landscape for indicated conditions. Historically, psychiatric pathologies have been treated with small-molecule compounds that have limited effect sizes and carry a variety of adverse effect profiles. Psychedelic medicines offer the opportunity to provide more potent and rapidly-acting treatments. It is crucial to note this is an emerging field of medicine, and only one of these compounds (esketamine) is currently FDA-approved for depression. The other compounds discussed are investigational, and this discussion is both imaginative and prospective in nature.
Stereotypes versus Preferences: Revisiting the Role of Alpha Males in Leadership
Authors: Wiezel Adi , Barlev Michael , Martos Christopher R. , Kenrick Douglas
Published: December 2023

Why are women underrepresented in positions of leadership? According to the “think manager-think male” model, leaders are stereotyped as male—and, in turn, as dominant—and this stereotype translates into preferences. However, status and leadership can be attained not only by dominance but also by prestige—a less sex-typed pathway. Five studies explored the relationship between leader stereotypes and preferences. University students spontaneously imagined both dominant and prestigious leaders as men (Study 1A, N = 148)—and this generalized across occupational domains (Study 1B, N = 220). However, they preferred women and prestigious leaders over men and dominant leaders. Study 2 (N = 2,692) found this preference for female over male leaders using a large nationally representative U.S. sample from the Pew American Trends Panel. Study 3 (N = 461) experimentally replicated the preference for prestigious female over dominant male leader candidates among university students. In Study 4, (N = 952) online MTurk participants judged politicians from face photographs and again showed a preference for women, which may have partially been due to the inference that women are more likely to use prestige- over dominance-based leadership strategies. Collectively, findings suggest that the belief that people prefer “alpha male” leaders, which might discourage women from pursuing leadership roles and others from nominating them, needs to be updated.
