Assessing the Quality of Machine Translation from Kurmanji Kurdish into English
Authors: Hazim M. Ameen Hakar , Ali Ahmed Hussein
Published: August 2023

The assessment of quality by the current most widely used on-line machine translation systems such as Google Translate and Bing Translator has always been a hotly debated and controversial topic.  This research endeavors to assess the translation quality of the already referred to on-line machine translation systems so as to highlight the level of their inadequate quality, if any. Yet, due to the nonexistence of a unique quality assessment method as far as the translation by the two systems is concerned, the current research sets out to utilize an error analysis method for assessing the quality of the translation of two specialized texts from Kurdish into English by Google Translate and Bing Translator systems. The error analysis of the chosen texts reveals that both systems achieved excellent results in the orthography category, with 100 and 98.7 percent accuracy for Google and Bing, respectively. Additionally, results of 98.8% for Google and 97.5% for Bing concerning  lexis reflected positive outcomes for both systems. Because both systems recently adopted NMT (neural machine translation), which simulates the way human brain functions to produce translation and learns from texts formerly translated by human translators, the two systems performed very well in these areas. The analysis also shows that the two selected systems were  successful in the translation of the selected texts with reference to English rules of grammar achieving outstanding results that are 99.6 accuracy for Google and 99.4 for Bing. For further research, this study recommends doing more assessment on translation of more types of Kurdish texts through conducting the linguistic error analysis.

Protection against expropriation of investments under the European Convention on human rights
Authors:   Mykolas Romeris University, Lithuania, Višinskytė Dalia , Čuveljak Jelena ,   University North, Croatia
Published: August 2023

International investment law protects investors from unlawful expropriation of investments by the host state. This article focuses on the problems of protection of investors against such unlawful actions by the state and the possible application of the right to property which is established in the European Convention on Human Rights as the possible defence mechanism. The purpose of this study is to assess whether, in cases of expropriation of investments, investors may effectively defend before the national tribunals relying on Article 1 of the Protocol 1 of the European Convention on Human Rights. The authors analyse complicated questions related to this problem, namely, whether investment shall be full under the notion of “property” under the said international convention, what kind of protection may be provided in case of expropriation of investment in the European Union Member States and how investors shall be compensated against the violation of their right to property in such cases. The authors use comparative, systematic analysis of deductive methods for the assessment of the relevant sources and formulation of the conclusions and proposals. The authors found that though the right to property under the European Convention on Human Rights protects foreign investments against expropriation, one of the most problematic issues related to the application of the right to property under this act in investment disputes is the question of fair compensation to investors.
Rent control: a friend or foe
Authors:   EKA University of Applied Sciences, Riga, Latvia, Snipe Arta
Published: August 2023

In this article, I address the by-product of the property reform—perpetual land lease—with a case study of Latvia. Contributing to scholarship on the challenge of property reforms after generations of dispossession, I examine the economic meaning of property restitution in this post-Soviet context. Using process-tracing and policy analysis techniques to examine the creation and implementation of Latvia’s restitution policy in the aftermath of independence from the Soviet Union, I tackle the research question: “Have the property rights of the parties been considered during these reforms?” I use two theories to answer this question: one of law and economics, by applying the theory of efficient regulation and Normative Hobbes Theorem (coalesced from the Coase Theorem and the Hobbes Theorem) and the other of transitional justice, by analysing the perpetual lease relations as part of restitution policy, aimed at providing justice to victims of the Soviet occupation and nationalization. In this paper, I illustrate that state intervention by normatively fixing the lease fee is necessary to prevent infringement of property rights of the landowners, thus ensuring that restitution as a transitional justice measure has reached its aim.
Healthcare Policies and Access: A Behavioural-Ecological Model Analysis
Authors: Sigamoney Claudia
Published: August 2023

The legacy of apartheid systems continues to be felt, especially in the country’s healthcare systems. Existing policies contribute to the inequality and challenges confronted when navigating healthcare services. This study uses the behavioural-ecological approach to analyse healthcare policy challenges hindering patients from accessing healthcare services in peri-urban communities in Johannesburg, South Africa. In addition, the study examines how poverty, poor infrastructure, and geographic location contribute to challenges facing communities in accessing healthcare services. A mixed-methods research was adopted; semi-structured interviews and field notes were used for data collection. Data were collected from outpatients, administration, and medical personnel. 173 respondents participated in the surveys, 14 participants were interviewed, and 12 respondents for focus groups. Statistical Package for the Social Sciences (SPSS) was used for quantitative data analysis and Nudist Vivo (NVivo) for thematic analysis. The study established that poverty, costly medical services, inability to communicate with healthcare providers, and low literacy were significant hindrances. It was revealed that unemployment contributed significantly to poverty levels, thus impeding access to healthcare services. The study concluded that South Africa needs a comprehensive social security system that provides adequate and sustainable social protection for peri-urban communities. The above remedial actions were recommended, but the public sector health reforms were negatively perceived. Thus, a conceptual model was developed to catalyse behavioural change in the public and private healthcare systems to achieve affordable and sustainable improvement in access and usage of healthcare services.
Strategies and Challenges of Converted Academic Library Spaces to Research Commons: A Case of Selected South African Libraries
Authors: Mugwisi Tinashe , Matatiele Refilwe
Published: August 2023

This paper sought to obtain a deeper understanding of the conversion strategies adopted by the selected South African university libraries and the subsequent challenges experienced thereof. This paper presents a case study for which data were collected through a qualitative-quantitative approach from the three public university libraries in the Gauteng province of South Africa, which had converted their spaces into the research commons (RC). The study sample consisted of the RC manager/librarian from each of the three libraries. The qualitative part of the study employed face-to-face interviews, non-participatory observation and information from websites. The quantitative approach used a structured questionnaire. Data were analysed using an inductive approach. Current library literature on RC does not encompass a holistic approach regarding how the conversion was planned and the challenges thereof. The study findings and recommendations include the formation of a research library consortium (RLC), ongoing user and space assessment to adjust services and resources to suit changing technologies, postgraduate needs and learning styles. Challenges included model misconception by librarians; planning and change management deficiencies; homogeneous staffing models; and budgetary constraints. The study recommends that essential conditions of the cultural commons (CC) be incorporated as the foundational RC conversion process to create a pool of collaboratively endorsed resources to enhance the mission of their parent institutions. The study also recommends that conversion should occur within a planned and collaborative framework to avoid the “tragedy of the commons” implementation and to preserve benefits derived for future sustainability.
The Electronic Records Appraisal Approach: A Case Study of the Construction Education and Training Authority
Authors: Mojapelo Makutla , Maleka Jane
Published: August 2023

In terms of the National Archives and Records Service of South Africa Act (NARSSA) (Act No. 43 of 1996), no record (regardless of form or medium) under custody of public entities shall be disposed of without the approval of the National Archivist. The National Archivist issues disposal authorities in enforcing this portion of the Act, which arise from the appraisal process as outlined in the 2002 policy guidelines. Whilst it is evident that NARSSA is not coping in the area of electronic records appraisal, it is critical for public entities such as the Construction Education and Training Authority (CETA) to have alternative measures in place. The purpose of this study is to evaluate electronic records appraisal approaches implemented by CETA. This qualitative study utilised interviews and document analysis to obtain data from participants purposively selected and various documents such as annual reports, strategic plans, and policies. The study established that CETA does not have a specific systematic approach to appraise electronic records, which is problematic for the organisation as it preserves everything regardless of its importance or value. The study recommends that CETA should benchmark with other organisations with sound and good electronic records appraisal systems with a common view to improve its current approach to electronic records appraisal.
Constructing the Nation through Talk: Social Media as a Tool for Banal Nationalism in Africa
Authors: Katiambo David Mugopi , Ooko Gloria
Published: August 2023

It was feared that the digital divide would deny citizens in developing countries opportunities for increased participation in politics through internet-enabled communication technologies. However, the divide has been bridged by citizens through the appropriation of Western technologies like internet access through mobile phones and cyber cafes. In fact, the difference between North and South in the use of the internet to participate in politics is quickly becoming unnoticeable, especially regarding the use of social media. This paper describes the unforeseen impact of the rapid adoption of social media in Africa, a continent that has been lethargic to other Western technological advances. The paper uses Anderson’s (1991/1983) theory of imagined community and Billig’s (1995) banal nationalism thesis to describe the role of social media groups in building banal nationalism, a process that unobtrusively legitimises the otherwise artificial nation-state. Through analysis of the activities of social media groups, the paper describes how, besides enabling the formation of social groups, social media has created a new sense of consciousness and deep attachment to the concept of a nation-state in Kenya.
Protecting Investors from the Repercussions of Unregistered Indigenous Property
Authors: Amadi-Echendu Anthea
Published: August 2023

Land registration is classified as a high priority in the pursuit of economic growth and development. However, many countries still operate under customary law, resulting in limited access to credit. External investors may be ignorant of the wide range of property rights. This article highlights the difference between indigenous and Westernised property rights and transfer processes, and the effect of indigenous property acquisition on initiatives for land development. Several international case studies are discussed. The study concludes that there is a need for indigenous properties to be recorded in the national land administration system. It is recommended for the current electronic registration system project in South Africa to investigate how the incorporation of indigenous property may occur. Recommendations for future studies are made.

Design principle of carbon supported single atom catalyst – interplay between d-band periodicity and local hybridization
Authors: He Zhengda , Wang Jingyang , Ouyang Bin
Published: August 2023

Carbon-based single atom catalyst has been widely investigated as a potential alternative for noble-metal-based catalysts for hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR). Rationale design of such catalysts require not only physical intuitions but also practical descriptors that can be directly applied in experiments. In this work, we establish a practical theoretical framework based on a comprehensive dataset of single atom catalyst compromising 28 metals, 5 types of local environments and adsorption calculations for 4 adsorbates (e.g., H/O/OH/OOH). We disentangle the complex trend of H/OH adsorption as an interplay between d-band periodicity and local hybridization, allowing for the estimation of catalytic performance based solely on the number of valence electrons. By utilizing this dataset and theoretical framework, we have also identified several promising catalyst candidates and overlooked design strategies.

Published: August 2023

Supported, bimetallic catalysts have shown great promise for the selective hydrogenation of CO2 to methanol. In this study, we decipher the catalytically active structure of Ni-Ga-based catalysts. To this end, model Ni-Ga-based catalysts, with varying Ni:Ga ratios, were prepared by a surface organometallic chemistry approach. In situ differential pair distribution function (d-PDF) analysis revealed that catalyst activation in H2 leads to the formation of nanoparticles based on a Ni-Ga face-centered cubic (fcc) alloy along with a small quantity of GaOx. Structure refinements of the d-PDF data enabled to determine the amount of both alloyed Ga and GaOx species. In situ X-ray absorption spectroscopy experiments confirmed the presence of alloyed Ga and GaOx and indicated that alloying with Ga affects the electronic structure of metallic Ni (viz. Ni-). Both the Ni:Ga ratio in the alloy and the quantity of GaOx are found to minimize methanation and to determine methanol formation rate and the resulting methanol selectivity. The highest formation rate and methanol selectivity are found for a Ni-Ga alloy having a Ni:Ga ratio of ~ 75:25 along with a small quantity of oxidized Ga species (0.14 molGaOx molNi-1). Furthermore, operando infrared spectroscopy experiments indicate that GaOx species play a role in the stabilization of for-mate surface intermediates, which are subsequently further hydrogenated to methoxy species and ultimately to methanol. Notably, operando XAS shows that alloying between Ni and Ga is maintained under reaction conditions and is key to attain a high methanol selectivity (by minimizing CO and CH4 formation), while oxidized Ga species enhance the methanol formation rate.

Published: August 2023

Density functional theory (DFT) is widely used to gain insight in molecule-metal surface reaction networks, which is important for a better understanding of catalysis. However, it is well known that generalized gradient approximation (GGA) density functionals (DF), most often used for the study of reaction networks, struggle to correctly describe both gas-phase molecules and metal surfaces. Also, GGA DFs typically underestimate reaction barriers due to an underestimation of the self-interaction energy. In this work we use a meta-generalized gradient approximation (mGGA) DF in combination with a non-local correlation DF for the first time to study a catalytically important surface reaction network, namely CO2 hydrogenation on Cu. We show that the mGGA DF used, namely rMS-RPBEl-rVV10, outperforms GGA- vdW DFs, especially in describing gas-phase molecules and predicting barriers. Hence, it is a better choice for constructing molecule-metal surface reaction networks.
Thermoelectric Properties of n-type CaTiO3, SrTiO3 and BaTiO3
Authors: Khan Alveena , Flitcroft Joseph , Skelton Jonathan
Published: August 2023

Mitigating anthropogenic climate change requires a package of technologies including methods to enhance the efficiency of the energy-intensive transportation and industry sectors. Thermoelectric (TE) power, which harnesses the Seebeck effect in a TE material to extract electrical energy from a temperature gradient, is a proven technology that could meet this need. Oxide-based TEs are desirable due to their low cost, high chemical stability, and low toxicity, but are generally limited by a low electrical conductivity and high thermal conductivity. In this study, we employ a fully ab initio approach to study the electrical and thermal transport and thermoelectric figure of merit ZT of the oxide perovskites CaTiO3, SrTiO3 and BaTiO3. We predict that carrier concentrations of n ≈ 10^21 cm^−3 are required to optimise the thermoelectric power factor, and the piezoelectric scattering in rhombohedral BaTiO3 limits the electrical conductivity compared to the other two systems. We find that the lattice thermal conductivity κlatt is primarily determined by the structure type and chemical bonding through the phonon group velocities. We predict that CaTiO3 and SrTiO3 can achieve ZT > 1 at high temperature, and that the ZT of SrTiO3 could be further enhanced by the impact of doping or alloying to obtain the required n on the κlatt. The favourable comparison to experimental measurements suggest that this modelling approach has considerable predictive power, and could therefore serve as a valuable complement to experiments to identify new high-performance oxide TEs.

Published: August 2023

Activated carbon (AC)-based materials have shown promising performance in carbon capture, offering low cost and sustainable sourcing from abundant natural resources. Despite ACs growing as a new class of materials, theoretical guidelines for evaluating their viability in carbon capture is a crucial research gap. We address this gap by developing a comprehensive set of criteria that underpin the success and scalability of AC-based materials. The most critical performance parameter is the CO2 adsorption energy, where an optimal range (-0.41 eV) ensures efficiency between adsorption and desorption. Additionally, we consider thermal stability and defect sensitivity to ensure consistent performance in varying conditions. Further, selectivity and capacity play significant roles due to external variables such as partial pressure of CO2 and other ambient air gasses (N2, H2O, O2), bridging the gap between theory and reality. We provide actionable examples by narrowing down our options to methylamine and pyridine grafted graphene.

Published: August 2023

This is simulation study on corrosion inhibition by surfactants via micelle formation and deposition on Iron (Fe) surfaces. Mainly focused on CTAB/SDS mixtures in aqueous solution at varying concentrations. Micelle properties, including size, shape, aggregation number, cluster size, and surfactant diffusion, were calculated and validated with experimental data. The coarse-grained Fe surface was modeled and validated against experimental water contact-angle data. Subsequently, the deposition of CTAB/SDS mixtures on the Fe surface and air-water interface was studied systematically. We found that the relative ratio of CTAB/SDS in the solution directly influences surfactant deposition behavior, which might impact the corrosion inhibition efficiency.
Investigating the Effects of Metformin and Inositol in the Treatment of Polycystic Ovary Syndrome: A Research Protocol
Authors: Aziz Mariam
Published: August 2023

Introduction: Polycystic Ovary Syndrome (PCOS), an androgen hormone excess and ovarian dysfunction disorder is linked to insulin resistance, metabolic disorders, and obesity. Inositol, a natural sugar compound is effective in regulating insulin levels and follicle stimulating hormones. Metformin, a biguanide drug which is used for Type 2 Diabetes treatment controls glucose levels and insulin resistance. Using inositol and metformin together for treatment of PCOS has been suggested to be beneficial for individuals with PCOS. The purpose of this study is to assess the effectiveness of metformin and inositol in improving insulin resistance, hyperandrogenism, weight, menstruation, and ovulation. Methods: A total of 36 women between ages of 25-35 clinically diagnosed with PCOS will be recruited to participate in a six-month double- blinded controlled trial. Participants were classified to normal BMI (18.5-24.0 kg/m2) and overweight/obese BMI (25.0-29.9 kg/m2 and >30 kg/m2) and were randomized into one of the following treatments: 500 mg of metformin with 4 g of inositol, 250 mg of metformin twice daily or two placebo sugar pills. Over the 6-month period, blood tests for blood sugar, insulin levels and testosterone levels, weight assessment on scale, menstruation questionnaire and ultrasound will be used to assess improvement in symptomology. Anticipated Results: It is anticipated that in both BMI groups, there will be a decrease in insulin resistance and hyperandrogenism with metformin and inositol use. There should be a reduction of weight in both BMI groups with increased effect seen in overweight/obese BMI. Menstruation and ovulation are anticipated to become more regular in both BMI groups using metformin and inositol. Discussion: Studies have found that metformin significantly improves insulin resistance, decrease circulating free androgens, and increases sex hormone binding globulin. Inositol has been seen to decrease insulin resistance, LH/FSH ratio and free androgen in women with PCOS. The combination of metformin and inositol is seen to improve hormonal and biochemical parameters and have a significant effect on menstrual cycle length. Conclusion: The combination of metformin and inositol may have synergistic effects that will PCOS symptomology and improve quality of life.

ABSTRAKPenggunaan lapis tambah pada perkerasan jalan adalah upaya untuk memperbaiki kondisi fungsional dan struktural, karena perkerasan jalan memiliki masa pakai yang terbatas. Seiring bertambahnya usia, kondisi jalan akan semakin buruk hingga memerlukan rehabilitasi. Penelitian ini bertujuan untuk mengembangkan perangkat lunak tebal lapis tambah bernama "OVRL" dengan mengikuti pedoman Pd T-05-2005-B menggunakan metode lendutan yang melibatkan alat Benkelman Beam (BB) dan alat Falling Weigth Deflectometer (FWD) yang dibuat dengan Borland Delphi. Perangkat lunak OVRL dapat digunakan sebagai pendamping Pd T-05-2005-B untuk mempercepat proses perhitungan karena seluruh tahap perhitungan telah tersedia dalam perangkat lunak tersebut. Analisis menggunakan perangkat lunak dapat mengurangi waktu dan kesalahan manusia dalam proses perhitungan yang kompleks. Hasil perhitungan menggunakan perangkat lunak OVRL memiliki tingkat kemungkinan kesalahan yang sangat kecil dengan rentang keyakinan 95%. Ini akan membantu mengurangi kemungkinan kesalahan manusia dalam proses perhitungan.Kata kunci: lapis tambah, perkerasan jalan, rehabilitasi, Borland Delphi, metode lendutan, perangkat lunak OVRL ABSTRACTThe use of additional layers on road pavement is an effort to improve the functional and structural conditions, as road pavements have a limited lifespan. As the age increases, the condition of the road will deteriorate to the point where rehabilitation is needed. This study aims to develop the "OVRL" software for calculating the thickness of the additional pavement layers, following the guidelines of Pd T-05-2005-B using the deflection method involving Benkelman Beam (BB) and Falling Weight Deflectometer (FWD) equipment created using Borland Delphi. OVRL software can be used as a companion to Pd T-05-2005-B to speed up the calculation process because all calculation steps are available in the software. The analysis using the software can reduce time and human errors in complex calculation processes. The results of the OVRL software calculations have a very small probability of error with a 95% confidence interval estimate. This will help reduce the possibility of human errors in the calculation process.Keywords: overlay, pavement, rehabilitation, Borland Delphi, deflection method, OVRL software

Introducción: El acné de la mujer adulta (AMA) es una enfermedad inflamatoria del folículo pilosebáceo que se presenta después de los 25 años, su prevalencia ha aumentado en los últimos años y se ha asociado a enfermedades endocrinas como el síndrome de ovario poliquístico (SOP). El objetivo es determinar la prevalencia del SOP clínico y bioquímico en mujeres colombianas con acné en la edad adulta en el servicio de dermatología y endocrinología.
Materiales y métodos: Estudio observacional descriptivo de corte transversal. Se incluyeron mujeres atendidas en la consulta de dermatología y endocrinología en 2 clínicas privadas de Bucaramanga, Santander durante el 2021. Los datos demográficos, clínicos, de laboratorio y diagnóstico se recopilaron mediante historias clínicas electrónicas y aquellas que asistieron a consulta externa.
Resultados: Se incluyeron 169 mujeres con acné con edad promedio 32,14 ± 5,62 años. El 44,97% presentó por primera vez acné después de los 25 años, el 34,91% persistió desde la adolescencia y el 20,11% restante reapareció. El 86,39% presentó acné inflamatorio, con preferencia en cara, seguido de espalda y tórax anterior. La severidad del acné fue leve en el 53,90%. La prevalencia del SOP fue del 62,13%, donde predominó el fenotipo A.
Conclusiones: el Acné de la mujer adulta es un marcador de hiperandrogenismo, siendo el SOP la causa más frecuente (6 de cada 10). Por lo tanto, se sugiere el estudio sistemático de SOP en mujeres adultas que consultan por acné.

El síndrome de la uña amarilla es una entidad pobremente descrita, con una prevalencia estimada de menos de 1/100.000 personas, presentándose principalmente en la sexta década de la vida. El diagnóstico es clínico, caracterizado por linfedema, manifestaciones respiratorias y uñas amarillas. Su etiología permanece desconocida; sin embargo, se han planteado algunas hipótesis como la disfunción linfática. Además, existe una relación entre las neoplasias malignas y este síndrome. No se ha descrito un tratamiento específico; sin embargo, el uso de vitamina E, antifúngicos, sulfato de zinc y macrólidos se ha considerado una terapia prometedora. Se documenta el caso de un adulto mayor que ingresó a urgencias con disnea, onicausis y edemas en extremidades inferiores.

Published: August 2023

El pioderma gangrenoso (PG) es una dermatosis neutrofílica inflamatoria descrita por primera vez por Brunsting et al. en 1930 (1,2). Es raro en la infancia, representando sólo el 4% de los PG; En los niños predominan pústulas que posteriormente se ulceran, siendo la presentación más común las lesiones ulcerativas múltiples y diseminadas, con compromiso principalmente de las extremidades inferiores (1). Típicamente se asocia con enfermedades sistémicas como enfermedad inflamatoria intestinal (EII), artritis reumatoide y discrasias hematológicas, sin embargo existen casos aislados. El diagnóstico se basa en los hallazgos clínicos y el curso de la enfermedad, además de descartar otras patologías, principalmente infecciosas. Los hallazgos histológicos pueden ser inespecíficos, sin embargo, ayuda en el diagnóstico, la presencia de pústulas subcórneas, infiltrado inflamatorio neutrofílico, fibrosis, ulceración y necrosis.

Gender Equality in and through Social Entrepreneurship in Ghana
Authors: Rexford Amankwah Ebenezer
Published: August 2023

This article identifies key priorities and challenges that lie in the path of achieving gender equality targets, particularly in Ghana where there is poverty and limited knowledge about Social Entrepreneurship. Although a growing body of research emphasizes the role of women in Social Entrepreneurship in developing countries, gender inequality is still persistent. In particular, we analyze the hindrances and implications of formalization policy for the attainment of SDG 5 in and through Social Entrepreneurship in Ghana. We also review Government policies, official documents, journals and propose solutions to government sector agencies and call attention to policy gaps with regard to the gender equality goals set by the international community and make recommendations for Ghana's formalization regulations.
Tenants’ Green Office Leasing Trends: an Exploratory Study of Budapest, Hungary
Authors: Huszár Barbara E.
Published: August 2023

Similarly to the international trends, tenant interest in green-certified office buildings has grown dramatically in Budapest in the past decade. By investigating the types of tenants who opt to lease office space in green-certified buildings in the Hungarian capital, this study aims to close a research gap. With using a mixed research method, results show that most of the green-certified office leasing transactions in Budapest between 2018-2022 were signed by tenants from IT, governmental and banking & finance sectors. Main reasons behind leasing green space are reputation, employee well-being and in the case of multinational companies, sustainability requirements from the parent company.
