Published: April 2023

Performance is the level of success of a person as a whole at a certain time in carrying out a task. Performance has the most important role, if performance decreases, it will gradually threaten the company and result in the company going bankrupt. Based on the phenomena and results of previous studies, the accounting information system is a component that can be streamlined to improve performance. Apart from Accounting Information Systems, accounting knowledge is considered very important for the Company. The cultural aspect is an aspect that greatly influences the effectiveness of the implementation of a technology. Technological developments must be followed by the desire of the community to increase their ability to utilize this technology. The population in this study is 238 Tourism Villages obtained from data from the Bali Provincial Tourism Office for 2022. The sample size is determined by calculating using the Slovin Formula and the proportional number of sample members is determined using the Yamane Formula. Based on the results of this study, the variable Accounting Knowledge has no significant effect on performance, both before the moderating variable (organizational culture) and after the moderation variable (organizational culture) and the variable Accounting Information System Effectiveness have a significant positive effect on performance. However, the existence of a moderating variable (organizational culture) shows that the effectiveness of the accounting information system variable has no significant effect on performance
Dialektics of Bicultural Identity in Intercultural Communication: A Phenomenological Study Approach
Authors: HALIMATUSA'DIAH Halimatusa’diah
Published: April 2023

This study aims to understand and analyze the ways in which bicultural individuals identify as Betawi people in building meaning about their identity in situations of intercultural communication. This study uses a qualitative approach that in its implementation uses a type of understanding. The subjects of the study were bicultural individuals in Jakarta who identified themselves as Betawi people. This study concludes that, first, the meaning of identity to be a Betawi Person is implemented by bicultural individuals by internalizing Betawi cultural values in their daily lives. Local wisdom "openness and equality", "living beneficially for others" and avoiding primordialism are values that are widely applied by bicultural individuals in all situations. Second, in the situation of intercultural communication, Betawi becomes the main identity used by informants. Meanwhile, occupational identity becomes the main identity in the context of intracultural meetings (ingroups). Third, this study also found differences in the ethos of figures caused by differences in age and types of daily activities carried out by the study subjects. This study recommends further research to explore the experiences of other subgroups such as the Betawi millennial generation.
NONPARAMETRIC NUMERICAL APPROACHES TO PROBABILITY WEIGHTING FUNCTION CONSTRUCT FOR MANIFESTATION AND PREDICTION OF RISK PREFERENCES
Authors: Wu Sheng , Chen Zhen-Song , Pedrycz Witold , Govindan Kannan , Chin Kwai-Sang
Published: April 2023

Probability weighting function (PWF) is the psychological probability of a decision-maker for objective probability, which reflects and predicts the risk preferences of decision-maker in behavioral decisionmaking. The existing approaches to PWF estimation generally include parametric methodologies to PWF construction and nonparametric elicitation of PWF. However, few of them explores the combination of parametric and nonparametric elicitation approaches to approximate PWF. To describe quantitatively risk preferences, the Newton interpolation, as a well-established mathematical approximation approach, is introduced to task-specifically match PWF under the frameworks of prospect theory and cumulative prospect theory with descriptive psychological analyses. The Newton interpolation serves as a nonparametric numerical approach to the estimation of PWF by fitting experimental preference points without imposing any specific parametric form assumptions. The elaborated nonparametric PWF model varies in accordance with the number of the experimental preference points elicitation in terms of its functional form. The introduction of Newton interpolation to PWF estimation into decision-making under risk will benefit to reflect and predict the risk preferences of decision-makers both at the aggregate and individual levels. The Newton interpolation-based nonparametric PWF model exhibits an inverse S-shaped PWF and obeys the fourfold pattern of decision-makers’ risk preferences as suggested by previous empirical analyses.

On the conjecture of Je$ \acute{\textbf{s}} $manowicz
Authors: Fan Nan , Luo Jiagui
Published: April 2023

Let $ k, l, m_1 $ and $ m_2 $ be positive integers and let both $ p $ and $ q $ be odd primes such that $ p^k = 2^{m_1}-a^{m_2} $ and $ q^l = 2^{m_1}+a^{m_2} $ where $ a $ is a positive integer with $ a\equiv {\pm 3}\pmod 8 $. In this paper, using only the elementary methods of factorization, congruence methods and the quadratic reciprocity law, we show that Je$ \acute{s} $manowicz' a conjecture holds for the following set of primitive Pythagorean numbers:

   \begin{document}$ \frac{q^{2l}-p^{2k}}{2}, p^kq^l, \frac{q^{2l}+p^{2k}}{2}. $\end{document}

We also prove that Je$ \acute{s} $manowicz' conjecture holds for non-primitive Pythagorean numbers:

   \begin{document}$ n\frac{q^{2l}-p^{2k}}{2}, np^kq^l, n\frac{q^{2l}+p^{2k}}{2}, $\end{document}

for any positive integer $ n $ if for $ a = a_1a_2 $ with $ a_1\equiv 1 \pmod 8 $ not a square and $ \gcd(a_1, a_2) = 1 $, then there exists a prime divisor $ P $ of $ a_2 $ such that $ \left(\frac{a_1}{P}\right) = -1 $ and $ 2|m_1, a\equiv 5 \pmod 8 $ or $ 2\not|m_2, a\equiv 3\pmod 8 $.
Feature screening for ultrahigh-dimensional binary classification via linear projection
Authors: Lai Peng , Wang Mingyue , Song Fengli , Zhou Yanqiu
Published: April 2023

Linear discriminant analysis (LDA) is one of the most widely used methods in discriminant classification and pattern recognition. However, with the rapid development of information science and technology, the dimensionality of collected data is high or ultrahigh, which causes the failure of LDA. To address this issue, a feature screening procedure based on the Fisher's linear projection and the marginal score test is proposed to deal with the ultrahigh-dimensional binary classification problem. The sure screening property is established to ensure that the important features could be retained and the irrelevant predictors could be eliminated. The finite sample properties of the proposed procedure are assessed by Monte Carlo simulation studies and a real-life data example.

Published: April 2023

Obtaining reliable information on the age structure of fish populations is important for making conservation and management decisions. We sought to evaluate precision and reader confidence in age estimates from scales (two body locations), sectioned fin rays (pectoral, pelvic, anal), and sectioned sagittal otoliths from Apache Trout Oncorhynchus apache (n = 78 fish) sampled from the East Fork White River, Arizona, in 2017. Two experienced readers without prior knowledge of fish length aged structures independently. Each reader provided a confidence rating of 0 (no confidence) to 3 (completely confident) as a measure of readability. Both readers were unable to estimate age from scales collected from the area just posterior to the insertion of the pectoral fin. We used scales removed from an area just dorsal to the lateral line and posterior to the dorsal fin in all analyses. Percentage of exact agreement between readers was highest for scales and otoliths (>72.0%) and lowest for fin rays (31.8–58.1%). Average confidence rating was highest for sectioned otoliths (mean ± SE, 2.1 ± 0.07), and lowest for anal fin rays (0.3 ± 0.06) and scales (0.7 ± 0.05). We compared consensus ages from otoliths to the other structures. Percentage of exact agreement with otolith age was low and varied from 21.6 to 35.7% among structures. Similarly, percentage of agreement within 1 y was also low among structures (58.0–70.2%). Scales consistently underestimated age of age-4 and older fish (based on otolith age), whereas fin rays tended to overestimate age of younger fish and underestimate age of older Apache Trout. Although sectioned otoliths require lethal sampling, they produced the most precise age estimates for Apache Trout with the highest reader confidence. Dorsal scales may be a suitable nonlethal alternative to otoliths if ages for only young fish (age 3 and younger) meet study objectives.

Board Diversity Evolution in the Iberian Stock Markets
Authors: Teodósio João , Vieira Elisabete S. , Madaleno Mara
Published: April 2023

This study aims to analyze the impact of women's presence on the board of directors on the outcomes of Spanish and Portuguese-listed firms over the third millennium. Based on a documental analysis of 44 publications, it is concluded that female directors positively affect the quality and transparency of the firm's reporting and compliance with the corporate governance codes. However, concerning financial outcomes, the literature does not robustly document the positive effects of such directors' characteristics on firm performance. Similar conclusions may be drawn for dividend and tax policies. These findings are consistent across different time frames of this millennium, indicating that they are not directly driven by gender quotas implementation. These results should interest Iberian governments, regulators, shareholders, investors, and financial markets.

Circular Supply Chain Case Studies in Aviation Sustainability
Authors: Mahama Abdul Jalil , Iyer Shankar Subramanian
Published: April 2023

In recent years, the prediction of the potential effects of environmental degradation by activities of various sectors including aviation has led to stakeholders calling for a change coupled with the adoption of sustainable and circular supply chain practices to assist mitigate against the projected harmful impacts of climate change. The UAE serves as a major aviation hub partly due to its geographical location, hence the operations of airliners must conform to the current practices which could reduce the number of pollutants such as Carbon Dioxide and other plastic waste. Corporate Social Responsibility considered a core practice towards the realization of sustainability objectives could be pursued by stakeholders in aviation, a norm that could compel management to enforce strategies to achieve Etihad's sustainability goals. The study employed qualitative thematic analysis to interpret various interview questions given by key informants. Purposive sampling was however used to solicit information relating to the chosen topic.
Global Supply Chain and Value Chain as a Relocation Strategy
Authors: Vargas-Hernandez José G. , Vargas-González Omar C.
Published: April 2023

This chapter aims to critically analyze the implications that the national protectionist policies have on the global supply and value chains and the relocation of production. The analysis is based on the assumptions that the global economy is facing the possibility of decoupling many trade connections, and this trend favors deglobalization processes that have long been promoted by populism, nationalism, and economic protectionism. It is concluded that global supply, production, and value chains, although being economically efficient, are no longer any more secure under national protectionist policies, and therefore, the relocation of production processes is mainly due to the increase in the level of income and wages of the developing countries that are the destination, and which reduce the advantages to relocate.
Exploring the Relationship Between Online Learning Trait Anxiety and Online Learning Academic Behavioural Confidence During COVID-19
Authors: A Chaleila Wisam , Qadan Enas , Gnaim-Abu Touma Lena , Amer Ahmad , Abu Akel Abeer
Published: April 2023

This study explores the relationship between online learning academic behavioural confidence (OLABC) and online learning trait anxiety (OLTA) during the COVID-19 crisis. The findings reveal that though students from multiple countries have experienced varied levels of anxiety, such anxiety has correlated positively with their OLABC. The researchers assume that COVID-19's deleterious effects on student online learning confidence have been moderated due to the prevalence of pandemic-related anxiety. Therefore, such anxiety has become passable and tolerated via adaptation and therefore should be viewed as “trait” rather than “state” anxiety. The researchers further believe that the quality of delivery methods is significant in determining the level of academic behavioural confidence, and hence, incessant and guided online teaching may produce a productive, effective, and interactive learning experience and uplift student ABC.
Theoretical Reflections on Education for Sustainable Development and Digital Technologies
Authors: Stoltenberg Ute , Michelsen Gerd
Published: April 2023

In this chapter the author discusses the relationship between digitalization and education from the perspective of the concept of education for sustainable development. The aim is to counter a development that sees digitalization as a natural phenomenon or as inevitable technological “progress” to which education must respond. The starting point of the discussion cannot be the many possible applications of digital technologies and the question of how they can best support current educational practice, but instead an understanding of education that needs to be made explicit along with the educational goals associated with it. The international as well as national education policy benchmark for an education that prepares us to meet the challenges of the future is the concept of education for sustainable development. In this chapter is it shown, based on this concept of education, both the potential and the limitations of the use of digital technologies for the design of educational processes.
The Impact of Biased Design and Hegemony on Sustainable Future-Ready Learning
Authors: Williams Kate Maloney , Halawani Jehad
Published: April 2023

The UN 2030 Agenda for Sustainable Development is committed to “quality education.” However, little actionable strategy remains on how to define and measure this goal, particularly in the face of an increasingly digitized future, fueled by emergencies and the need for quality distance learning. Additionally, to achieve SDG 4 in a digital era, societies must undergo substantial reforms in 1) conceptualizing teaching, learning, and assessment, and 2) designing and exporting technology. The successful uptake of new technology is frustrated by a complex array of ecological conditions, hegemonic power structures, and multifaceted digital divides. Through a systems approach, this chapter explores how digital environments function and create barriers. The authors argue that effective technology-based interventions must include awareness of the externalities that impact digital design, providing examples from the Global South. The chapter concludes with recommendations on the transformation needed for successful implementation and sustainable integration.
Enabling Education for Sustainable Development Through Digital Storytelling
Authors: Makrakis Vassilios , Kostoulas-Makrakis Nelly
Published: April 2023

Digital storytelling and participatory video (PV) are closely linked since they share common objectives, development tools, and methodologies. They are not just informative but purposefully aim to empower, educate, and activate people toward building a more sustainable and just society. This chapter describes both digital storytelling as a tool and as a teaching and learning methodology applied in an Erasmus+ project in Southeast Asia. It has been revealed that the interaction between digital technology and education for sustainability creates new opportunities to address sustainability, as well as new challenges. The teachers trained produced digital storytelling/PV applications that can be categorized as “authentic” learning activities addressing issues in the “real world.” It was widely assumed that teachers involved in this process learned to view teaching and learning from alternative ways, feeling ownership and control of their own learning and experiencing a sense of contribution to society and the environment.
A Novel Epitope Dataset: Performance of the MCL-Based Algorithms to Generate Dataset for Graph Learning Model
Authors: Solihah Binti , Musdholifah Aina , Azhari Azhari
Published: April 2023

Naturally, the epitope dataset can be presented as a graph. Dataset preparation in the previous methods is part of model development. There are many graph-based classification and regression methods. Still, it is difficult to identify their performance on the conformational epitope prediction model because datasets in a suitable format are unavailable. This research aims to build a dataset in a suitable format to evaluate kernel graph and graph convolution network. This dataset, which results from graph clustering on graph antigens, can be used to identify the performance of many graph neural network-based algorithms for conformational epitope prediction. The Ag-Ab complexes that meet the criteria for forming a conformational epitope prediction dataset from previous studies were downloaded from the Protein Data Bank. Raw datasets in the form of specific exposed antigen chain residues are labeled as epitope or non-epitope based on their proximity to the paratope. The engineering features in the raw dataset are derived from the structure of the antigen-antibody complex and the propensity score. Aggregating atomic-level interactions into residual levels create an initial graph of the antigen chain. The MCL, MLR-MCL, and PS-MCL are graph clustering algorithms to obtain labeled sub-clusters from the initial graph. A balance factor parameter is set to several values to identify the optimal dataset formation based on minimal fragmentation. The output of the MCL algorithm is used as a baseline. As a result of the fragmentation analysis that occurs, the MLR-MCL algorithm gives the best model performance at a balance factor equal to 2. PS-MCL gives the best performance at a value of 0.9. Based on the minimum fragmentation, the MLR-MCL algorithm provides the best model performance compared to MCL and PS-MCL. The dataset in a format according to benchmarking dataset can be used to identify the characteristics of antigen subgraphs formed from the graph clustering process and to explore the performance of graph-based learning conformational epitope prediction models such as graph convolution networks.
Carbon Fibers Doped by Binary Phosphides as an Electrocatalytic Layer for PEM Electrolysers
Authors: Bera Cyril , Streckova Magdalena
Published: April 2023

Hydrogen evolution reactions (HER) are important in a variety of electrochemical devices, such as electrolysers and fuel cells. To reduce the reaction overpotential and reduce energy consumption, efficient, low-cost, and durable electrocatalysts must be developed. Needle-less electrospinning (NLE) technique was used to prepare the fibrous electrocatalyst. NLE is a user-friendly and adaptable technique for large-scale low-cost fiber production. NLE created transition metal phosphides carbon fibers (TMP CF). The precursor foam was folded between two Al2O3 ceramic plates. The heat treatment was carried out in a tube furnace at 1200 °C in an Ar atmosphere, followed by a reduction in an H2 atmosphere at 780 °C. The electrolyser's membrane electrode assembly can be immediately submerged in the final TMP CF in the form of plates. The created NiCoP catalytic plates could be directly used in electrolyser's membrane electrode assembly of PEM electrolysers. In a three-electrode system, the electrochemical activity of the produced electrocatalysts was evaluated using linear sweep voltammetry. The electrochemical activity of the produced electrocatalysts were evaluated using linear sweep voltammetry. The catalyst's stability and endurance in acidic and alkaline environments were investigated.

Authors: Brlić Tin , Jandrlić Ivan , Mrkobrada Lorena
Published: April 2023

In this paper, tests were performed by monitoring changes of strain amounts and their distribution by digital image correlation during static tensile testing of steel. The influence of different combination of speckles application on the sample surface (white speckles on the black sample surface and black speckles on the white sample surface) during cold deformation of steel was tested with the non-contacting digital image correlation. Strain amounts obtained by digital image correlation analysis of tested samples, with white on black and black on white painted speckle patterns, were compared. Different analysis for determining and monitoring strain amounts, provided by digital image correlation software, were used in this paper. The strain amounts were compared during cold deformation until the occurrence of sample fracture in both combinations of speckles application on the sample surface. Research has shown the importance of proper sample preparation for determination strain amounts and insignificant minor differences of strain amounts, between different sample preparations for digital image correlation, during cold deformation of tested steel.
The nucleus of differentiated root plant cells: modifications induced by arbuscular mycorrhizal fungi
Authors: Lingua G , Fusconi A , Berta G
Published: April 2023

The nuclei of plant cells show marked differences in chromatin organisation, related to their DNA content, which ranges from the type with large strands of condensed chromatin (reticulate or chromonematic nuclei) to one with mostly decondensed chromatin (chromocentric or diffuse nuclei). A loosening of the chromatin structure generally occurs in actively metabolising cells, such as differentiating and secretory cells, in relation to their high transcriptional activity. Endoreduplication may occur, especially in plants with a small genome, which increases the availability of nuclear templates, the synthesis of DNA, and probably regulates gene expression. Here we describe structural and quantitative changes of the chromatin and their relationship with transcription that occur in differentiated cells following an increase of their metabolism. The nuclei of root cortical cells of three plants with different 2C DNA content (Allium porrum, Pisum sativum and Lycopersicon esculentm) and their modifications induced by arbuscular mycorrhization, which strongly increase the metabolic activity of colonised cells, are taken as examples.
Extracellular polysaccharides are involved in the attachment of Azospirillum brasilense and Rhizobium leguminosarum to arbuscular mycorrhizal structures
Authors: Bianciotto V , Andreotti S , Balestrini R , Bonfante P , Perotto S
Published: April 2023

Arbuscular mycorrhizal (AM) fungi, one of the most important component of the soil microbial community, establish physical interactions with naturally occurring and genetically modified bacterial biofertilizers and biopesticides, commonly referred to as plant growth-promoting rhizobacteria (PGPR). We have used a genetic approach to investigate the bacterial components possibly involved in the attachment of two PGPR (Azospirillum and Rhizobium) to AM roots and AM fungal structures. Mutants affected in extracellular polysaccharides (EPS) have been tested in in vitro adhesion assays and shown to be strongly impaired in the attachment to both types of surfaces as well as to quartz fibers. Anchoring of rhizobacteria to AM fungal structures may have special ecological and biotechnological significance because it may facilitate colonisation of new rhizospheres by the bacteria, and may be an essential trait for the development of mixed inocula.

Published: April 2023

Purpose Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses.Materials and Methods Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted.Results UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients.Conclusion Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.

The prevalence of soil-transmitted helminths (STH) is high in communities within the Peruvian Amazon despite repeated mass-drug administration, demanding alternative strategies of control. Smartphone-attached microscopy (SAM) permits visualization of STH from a small portable microscope through a smartphone screen, potentially providing an inexpensive and rapid method of STH visualization in communities where diagnostic laboratories with microscopes are inaccessible. In this study, a total of 45 community health workers who work within the health systems of Loreto, Peru, attended a 1-day training session with lectures and practicums on STH and SAM. Participants received a pre- and post-intervention questionnaire. Post-intervention, participants were significantly more confident using SAM and identifying parasite images, symptoms, transmission, and treatment (P ≤ 0.0045). Post-intervention, participants correctly labeled a median of five of seven SAM apparatus components and five of eight steps of Kato–Katz technique, were less likely to choose taking medicine to prevent parasite infection (P = 0.0075), and were more likely to select Kato–Katz technique as a type of diagnostic test (P < 0.0001). Most participants felt ready to use SAM in their communities and stated that it could help rural communities far from health centers or laboratories (24%); provide faster identification, results, diagnosis (19%); permit at-home or on-the-spot visualization (14%); and save money (14%). Results show that community health workers show a high level of willingness and competency to learn about both STH and SAM and may be a yet-unexplored practical method of augmenting STH visualization, bringing healthcare to communities in Loreto with poor access to diagnostic laboratories and clinics.

This project’s objective was to generate experimental data to evaluate the impact of metals doped B20 on diesel particle filter (DPF) ash loading and performance compared to that of conventional petrodiesel. The effect of metals doped B20 vs. conventional diesel on a DPF was quantified in a laboratory controlled accelerated ash loading study. The ash loading was conducted on two DPFs – one using ULSD fuel and the other on B20 containing metals dopants equivalent to 4 ppm B100 total metals. Engine oil consumption and B20 metals levels were accelerated by a factor of 5, with DPFs loaded to 30 g/L of ash. Details of the ash loading experiment and on-engine DPF performance evaluations are presented in the companion paper (Part I). The DPFs were cleaned, and ash samples were taken from the cleaned material. X-ray Fluorescence (XRF), X-Ray Photoelectron Spectroscopy (XPS) and X-Ray Diffraction (XRD) were conducted on the ash samples. Core samples were taken from the cleaned DPF and were subjected to scanning electron microscope energy dispersive x-ray spectroscopy (SEM-EDS) and XRF analysis. A comparison of the data from the two DPFs is presented. The XRD and XPS analysis showed that the compounds present in the ash from the two DPFs were nearly identical, though differing in concentrations. CaSO4 was the biggest component of the ash from both DPFs. The metals doped B20 fuel resulted in ash with similar characteristics to that deposited by the lube oil and did not appear to have any deleterious physical effects on the DPF substrate (did not penetrate the substrate).

Published: April 2023

This study examined diversity and similarity of orientations for renewable energy policies across US states through frame analysis based on semantic topic modeling technique. More specifically, it analyzed Renewable Portfolio Standard (RPS) bills of 29 RPS adopted states. Latent Dirichlet Allocation (LDA) modeling for semantic topic analysis was applied to explore hidden meanings within text bills, as well as shared patterns of the meanings among states, by utilizing latent information of nested topic. It found two major themes of the definition of eligible renewables and implementation mechanisms, underlying the states’ RPSs substantially contributed to framing each state’s renewable energy policies. In accordance with the state’s energy situation and socio-economic interests in renewable energy, however, states’ frames for defining eligible renewables and for building implementation and compliance mechanisms differed substantially.

Authors: Čvorović Dragana
Published: April 2023

One of the most important features of the criminal procedural legislation of the Republic of Serbia is the institute of conditional deferral of criminal prosecution as a key aspect of the principle of opportunity, which was standardized in order to create a normative basis for increasing the efficiency of criminal proceedings. The subject of the paper is an analysis of the extent of the application of the institute, both in general and in terms of the structure of some of the obligations imposed on the suspect by the public prosecutor during the deferral of criminal prosecution in the Republic of Serbia from 2019 to in 2021. The aim of the paper is to point out the exceptional importance of the institute and to point out the fact of the necessity of both the adequate normative elaboration of the institute and its adequate application.
Colonial Governance System in Pakistan: A Case Study of South Waziristan, Newly Merged District

This paper discusses the former colonial governance system based on special set of laws known as Frontier Crimes Regulation (FCR) in the erstwhile FATA (Federally Administered Tribal Areas, present-day Newly Merged Tribal Districts). The main purpose of the research is to provide an argument that the colonial governance structure was not the only cause for the widespread militancy in South Waziristan, part of the Newly Merged District. From in-depth interviews with different stakeholders and literature review, it is found out that the FCR with all its inherent faults was deemed successful in the administration of the North West Frontier and it was not responsible for the militancy in the tribal district of South Waziristan. Thus, the paper analyzes the old governance system prior to the spillover of militants and it reaches to the conclusion that the FCR proved to be an effective tool for the political administration of the border area of South Waziristan in both the colonial and post-colonial periods. The study emphases that mismanagement, corruption and incompetency of bureaucracy has led to the weakening of FCR, traditional institutions of dispute resolution and the indigenous leadership model thereby creating leadership vacuum which was in turn filled by the militants. The study has employed ethnographic based data collection techniques to reach the findings that old administrative structure is not responsible for the chaos and militancy in South Waziristan.

Megalithic Skyscapes in Galicia
Authors: González García A. César , Criado-Boado Felipe , Vilas Estévez Benito
Published: April 2023

We present the results of our analysis of two singular Neolithic monuments and two prominent megalithic groups in Galicia. The two singular monuments are the dolmen of Dombate (Baio, Coruña county), perhaps the largest megalithic chamber in Galicia (or at least the most investigated and well-known) that houses an elaborate decorative program with engravings and paintings, and Forno dos Mouros (Bocelo mountains, Coruña county), also housing paintings and belonging to a bigger group aligned along an historical path following the mountain ridge. Both chambers house interesting illumination effects. The group analysis concerns the Barbanza (Coruña county) and Leboreiro, (Ourense county and borderland with Portugal) necropoleis. There, we find that apart from chamber orientation, location and spatial relations of the monuments within the landscape, the monuments incorporate skyscape associations that complemented and dialogued with that of the chamber orientations. Besides, if the particular directions that we find are related to the movements of the sun and/or moon they may indicate the appropriate ritual time for the dead. Of course, skyscape is not the only or the main factor to explain the location of the mounds within the necropolis but are part of a complex system of relations making those monuments part of a cultural landscape. When taking all factors into consideration a complex picture emerges where we can envisage the ways of construction of social time and space in the megalithic period.
