The Language of Liberation and Perpetual Eternity
Authors: Pillay Anton M.
Published: April 2022

The incarceration of the former South African President Jacob Zuma on charges of contempt of court sparked mass looting, destruction, and damage to a staggering economy attempting to navigate through Covid-19-related repercussions. Early estimates reveal that the initial damage report bill is a R50 billion knock on the country’s Gross Domestic Product (GDP). The level of orchestration behind the attacks alludes to state-sponsored violence, given Mr Zuma’s loyal sympathisers within the intelligence community and in the African National Congress. This research postulates that Mr Zuma’s political rhetoric served as the main inciting factor behind the destruction. Indeed, comparative analysis shows how many post-independence/liberation leaders have invoked a language of debt by virtue of their role as independence/liberation heroes to justify dismal governance records. What are the key features of this language of debt?
Some Pitfalls of Decoloniality Theory
Authors: Hull George
Published: April 2022

Decoloniality theory, with its signature concepts coloniality of power and coloniality of knowledge, initially emerged in Latin America. It has been developed further in southern Africa, where it now has significant influence in some universities. Decoloniality theory has to be distinguished from the broader endeavour of intellectual decolonization. The latter includes all intellectual efforts to free theory and ideology from distorting bias which is the effect of colonial or neocolonial power relations. Intellectual decolonization in this broader sense (e.g., in the writings of Anthony Appiah and Kwasi Wiredu) is truth-oriented: it aims to expose incorrect claims which are the result of bias, replacing them with correct theoretical conclusions. By contrast, contemporary decoloniality theory (e.g., in the writings of Walter Mignolo and Sabelo Ndlovu-Gatsheni) embraces several contentious metaphysical ideas, among which is rejection of the very possibility of universal truth. When decoloniality theory first emerged (in Aníbal Quijano’s innovative writings) out of the discipline of political economy, however, it exemplified the broader, truth-oriented sense of intellectual decolonization. Quijano, and later Ramón Grosfoguel, were concerned to expose several false theoretical claims in social science which are a legacy of Eurocentric bias. Here I argue that tracing the steps by which contemporary decoloniality theory developed from this starting point can reveal some of its principal shortcomings. I seek to show that several of the distinctive metaphysical ideas in contemporary decoloniality theory are founded on drastically undermotivated, hyperphilosophising inferences from empirical premises. Even considered purely on its own terms, I argue, contemporary decoloniality theory exhibits a number of weaknesses and contradictions.
Ethnic Propaganda, Hate Speech, and Mass Violence in Igbo-Hausa/Fulani Relations in Postcolonial Nigeria
Authors: Adeyeri James Olusegun
Published: April 2022

Opinions are divided on the conduct and nature of the 1967–70 Nigerian civil war, occasioned partly by the Igbo secession and declaration of the Republic of Biafra. Some believe that the Nigerian government adopted a genocidal war strategy characterised by mass violence against civilians, aggressive blockade of the eastern region, artificial famine, and hateful/threatening utterances by many military commanders, accompanied by about one million civilian casualties. On the other hand, some are of the view that the actions of some Nigerian military officers and men were not in consonant with the position of the Nigerian government during the war, but were influenced by their animosity towards the Igbo. In post-civil war Nigeria, Igbo-Hausa/Fulani relations and political discourses are increasingly tense and indicative of a fearful resurgence of mass violence due to prevalent lies, propaganda, and misrepresentations –verbally, on paper, and online/on social media – particularly among the youths on both sides. This paper argues that the historical crisis-ridden relations between the Igbo and the Hausa/Fulani, the attendant 1966 mass killings of Igbos in the north, the nature of the war strategies of the federal government during the civil war, and the currently mounting tension are all direct results of contending ethnic propaganda including hate speech, lies, and name-calling in a bid to gain political and strategic advantages over other ethnic groups. Thus, this paper is a historical inquiry into the role of propaganda and hate speech in socio-political interactions, discourses, and incitements of mass violence among the heterogeneous Nigerian population, particularly the Igbo and the Hausa/Fulani. The paper proposes legislative, constitutional, and active citizenship advocacies to address the menace. The article utilises primary and secondary sources to analyse and interpret the subject-matter of the paper.
Natural Gas Production in Mozambique and the Political Risk of Islamic Militancy
Authors: Neethling Theodor
Published: April 2022

The Cabo Delgado province in the northernmost portion of the long Mozambican seaboard is now home to Africa’s three largest liquefied natural gas (LNG) projects, and these projects have attracted many of the world’s major multinational energy companies, accompanied by massive LNG investments. There can be little doubt that the discovery of rich gas reserves is a potential game changer for the Mozambican economy and development agenda. It is potentially an opportunity for the rapid advancement of a country that currently ranks close to the bottom of the United Nation’s Human Development Index. However, despite the billions in investments from major multinational energy companies, the people of Cabo Delgado are yet to see the material benefit from these projects. One of the biggest risks to investors in the LNG industry is the many unknowns pertaining to the threat posed by the militant Islamic movement, Ansar al-Sunna, which has especially been active since 2017 in the Cabo Delgado province. In view of this, this article assesses Mozambique’s LNG industry and the political risks associated with the insurgent movement’s intention to establish an Islamic caliphate in the Cabo Delgado area.
Another Bloody Clean-Up
Authors: Du Toit David , Whaley Buck
Published: April 2022

South Africa has one of the highest violent crime rates globally, where physical and emotional trauma is used in homicides and suicides. While this is apparent to the ordinary South African, what is less clear is what happens after the police and forensics have done their job at a crime scene: Who cleans up the bloody mess? In South Africa, as in many other nations, trauma cleaners restore the scenes where homicides and suicides have been committed, and where industrial accidents have taken place. Little to no scholarly research has been conducted on the experiences of the cleaners of trauma scenes. Cleaning up these scenes consists of labour charged with violence that most cannot countenance, but which the cleaner must face. Drawing on 13 qualitative interviews, this article explores the challenges of cleaning up a site where violent and/or traumatic acts have occurred, and how the cleaners develop strategies to cope with their own concomitant trauma. The cleaners are exposed to various health and safety issues, as well as the emotional trauma associated with cleaning up horrific accidents and crimes. Findings show that trauma cleaners emotionally distance themselves from the violence to which they bear witness and use emotional labour, spirituality, humour, and debriefing as coping strategies. In its conclusion, this article suggests a greater acknowledgement of trauma cleaners’ responsibilities and recommends that proper physical and emotional training is necessary to ensure their wellbeing.
Black Africans’ Contributions to Global Industrial Revolutions
Authors: Uwizeyimana D.E.
Published: April 2022

This article evaluates the contributions that have been made by Black Africans (in Africa and the diaspora) to the different industrialrevolutions. The methodology used in this research was mainly qualitative. The findings confirm that Black Africans had achieved technological advances before the arrival of Western and Eastern slave traders and colonialism in Africa, and had made substantialcontributions to the pre-industrial revolution and the first industrial revolution. Even though slavery and colonisation halted further technological innovation and advancements, there is strong evidence to suggest that Black Africans are currently contributing to theFourth Industrial Revolution. Impressive innovations are coming from Africa. African leaders must support Africans’ technological innovations through funding, proper training, and availing raw materials for them to contribute to the Fourth Industrial Revolution.
Artificial intelligence as a tool of public diplomacy
Authors: Williams Robyn , Otto Lisa
Published: April 2022

Iran and the United States (U.S.) have had a volatile relationship for decades, with continuous threats of violence, sanctions, and internet blocks. In the last decade, we have seen a third force at play as technology becomes an integral aspect of diplomatic relations. The last three U.S. administrations have displayed mixed attempts at salvaging diplomatic relations with Iran. This article explores how artificial intelligence driven communication can be a critical tool in improving the relationship between the two states. Utilising a desktop research approach, exploring primary and secondary literature, this article explores possible artificial intelligence solutions to improve the communicational aspect in the public diplomacy between Iran and the U.S. It is evident that artificial intelligence has had negative implications on the public diplomacy between the two states as we witness the increasing use of deep-fakes and websiteblocks. However, processes such as natural language understanding allows governments to have more targeted foreign policy objectives and language translation creates a direct and enhanced line of communication between the state and foreign audience.
Beyond Sub-Imperial War, ‘Blood Methane’, and Climate-Debt Denialism
Authors: Bond Patrick
Published: April 2022

South Africans really must confront two conjoined crises that affect both the majority here, and the vast majority next door in Mozambique. First, the climate catastrophe’s amplification due to rising dependency upon Liquefied Natural Gas (which is more than 80 times more potent than carbon dioxide in coming decades), leaving our neighbour as the world’s fourth worst-affected country since 2000, at a time when South Africa is already the third-highest greenhouse gas emitter per person/ GDP among major countries. Second, the deplorable trajectory of Pretoria’s sub-imperialist adventurism, now represented by the army’s deployment in CaboDelgado province in order to promote gas drilling by multinational corporations. In part because of the corrupt, repressive Maputo government, many Southern African civil society organisations regularly appeal for an end to both Mozambique’s ‘blood methane’ war and, behind it, the fossil fuel extraction that amplifies the climate crisis. The innovative demand is for Global-North payment of climate reparations to victims of extreme weather, plus financial compensation so as to leave the world’s fourth-largest gas ftield unexploited. Against these arguments and movements, there is a vociferous South African lobby—which can be termed ‘laptop bombardiers’—ignoring or brazenly dismissing both crises: climate and the danger of further sub-imperial mishaps. It is long overdue to confront this lobby by objecting to damaging fossil fuels and militarism, and call it to account for the vast ethical lapses in their analyses.

Authors: Izhar Tejwar , Chakraborty Manigopa , Ali Naiyar
Published: April 2022

Green forages are rich and cheapest source of carbohydrates, protein, vitamins and minerals for dairy animals. To meet out the needs of the ever increasing livestock population the production as well productivity of fodder is to be increased. Maize crop has an important place in the food grain basket of our country and is the third most important versatile food grain crop due to its importance in food, feed, specialty corn, starch etc. In this experiment, twelve inbred lines were crossed with each of five testers in a line×tester design to evaluate combining ability and heterosis to identify promising hybrids of green cob and baby corn for fodder purpose with various characters like, 50% tasseling, 50% silking, 75% dry husk, grain yield, no. and weight of green ears, green fodder yield, dry weight, pericarp thickness and various quality parameters. The resulting F1s along with three checks and seventeen parents were evaluated in two environments during kharif 2010 and rabi 2010-11. Crosses excelled their perspective parents in performance for most of the traits studied. BQPM-2 among the parental lines and BAUIM-2 among the testers were identified as the best general combiners for grain yield and green fodder yield. Whereas among the hybrids, BAUIM-4×HKI-163 and BQPM-2×HKI-163 were identified as potential cross combinations for grain yield and green fodder yield. However for quality parameters, BQPM-2×BAUIM-2 exhibited the highest magnitude of economic heterosis for calcium, crude fibre, dry ash and reducing sugar contents while for iron and phosphorus contents, BAUIM-4×HKI 163 exhibited the most desirable value of heterosis. So the crosses (BAUIM-4×HKI 163) and (BQPM-2×BAUIM-2) can be utilized for developing high yielding hybrid varieties as well as for exploiting hybrid vigor. While for baby corn as feed for animals, several quality parameters like moisture, calcium, iron, phosphorus, total soluble sugars, crude fibre and dry ash contents) baby corn yield were studied. The inbred line BAUIM-4 followed by BQPM-2 was a good general combiner for all the quality traits and baby corn yield. Single cross BQPM-2 × BAUIM-2 had positive significant specific combining ability effects for all the quality traits and baby corn yield
PENGARUH KOMBINASI GYPSUM DAN FLY ASH TIPE C PADA KUAT TEKAN MORTAR
Authors: Rahman Aulia
Published: April 2022

The use of gypsum and fly ash is very common in construction of Indonesia. Both of these materials are used because of Indonesia's rich natural potential. Gypsum was chosen because it has the same chemical composition as cement, which is calcium (Ca), while type C fly ash also shows the same content. By combining the two materials, the researchers tried to study their impact on the compressive strength of mortar. The proportion of cement was reduced from 100%, 50%, 25%, and 0%, while the rest was replaced by a combination of gypsum and type C fly ash. Then, the samples were tested at the age of 7 and 14 days to see the compressive strength performance on early days of hardening. Samples with no substituent composition showed the highest compressive strength of 23.3 MPa, then it continued to decrease as the cement mixture became less, until the lowest was 7 MPa in samples composed only of gypsum and fly ash. There was a significant increase in performance of sample 4 which only contained 25% cement, but it was indicated that the cause was not due to composition, but other factors such as water ratio and compaction.

Keywords: gypsum, type C fly ash, mortar.

Authors: Irfan Muhammad , Qureshi Abdul Rasheed , Sajid Muhammad , Ashraf Zeeshan
Published: April 2022

Background: Pulmonary tuberculosis is a tremendous public health problem, increasing significantly, especially in developing countries. Getting a TB-free globe appears to be not more than a dream. Mycobacterial culturing is the gold standard for precise diagnosis but requires six-week time, in the meantime, patients remain a source of inadvertent disease dissemination in the community. The unavailability of sputum also poses a challenge several times. As adenosine deaminase level measurement is easy, rapid and independent of a sputum sample, this study was conducted to determine the diagnostic efficacy of adenosine deaminase activity for pulmonary tuberculosis.Patients and methods: This prospective study was conducted at Pulmonology-OPD, Gulab Devi Chest Hospital, Lahore, from 01-01-2019 to 30-06-2019. A total of 300 sputum smear-positive patients with clinical and radiological evidence consistent with diagnosis of pulmonary tuberculosis and 30 normal participants without any clinical, radiological or haematological evidence of tuberculosis were included. While, smear-negative patients and those having any evidence of hepatic disease, hematopoietic malignancy, infectious mononucleosis, typhoid or pregnancy were excluded. The serum ADA level of each participant was determined. All patients were subjected to AFB culture. Diagnostic accuracy was determined by considering sputum culture as a gold standard.Results: At cut-off value of >15 IU/L, a sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 98.30%, 100.00%, 100.00%, 85.71%, 98.46% respectively were defined.  Conclusion: Serum ADA level, having excellent sensitivity and specificity, can diagnose pulmonary tuberculosis even if sputum sample is not available.

Road bridge reconstruction design analysis
Authors: PIECHOTA Mieczysław , MIKULSKI Erik
Published: April 2022

This paper presents a case study entailing the reconstruction of a road bridge. The original timber construction low-level bridge with rolled steel girders had lost its performance parameters due to biological corrosion of the structural timbers. The support piles were defective. The structure was taken out of use and a solution was proposed in the form of a composite span structure founded on prefabricated reinforced concrete piles. It is important to pay attention to the economic considerations of the reconstruction, as managers of lower category roads often only have a rather limited budget.

Active control of terahertz wave assisted by dielectric loaded plasmonic waveguide
Authors: Huaiqing Liu  , Mengya Yang  , Xue He  , Youchao Jiang  , Xiancun Zhou  , Maosheng Fu
Published: April 2022

We propose and numerically investigate a directional coupler which consists of two dielectric loaded InSb based terahertz (THz) plasmonic waveguides. Owing to the permittivitly tunable property of InSb, the coupling strength between the two dielectric loaded plasmonic waveguides is affected by temperature, so the maximum power coupled from the input waveguide to the cross-waveguide and the correspondingly coupling length could be effectively tailored by altering temperature. Under different temperatures, this directional coupler could act as a thermally controlled terahertz wave switch or a 3-dB terahertz splitter around the frequency of 1.17 THz. This ultracompact and thermally controlled plasmonic directional coupler may find potential important applications in the highly integrated photonic circuits for terahertz system and technologies.
On 1-Subdivisions of Transitive Tournaments
Authors: Kim Jaehoon , Lee Hyunwoo , Seo Jaehyeon
Published: April 2022

The oriented Ramsey number $\vec{r}(H)$ for an acyclic digraph $H$ is the minimum integer $n$ such that any $n$-vertex tournament contains a copy of $H$ as a subgraph. We prove that the $1$-subdivision of the $k$-vertex transitive tournament $H_k$ satisfies $\vec{r}(H_k)= O(k^2\log\log k)$. This is tight up to multiplicative $\log\log k$-term.

We also show that if $T$ is an $n$-vertex tournament with $\Delta^+(T)-\delta^+(T)= O(n/k) - k^2$, then $T$ contains a $1$-subdivision of $\vec{K}_k$, a complete $k$-vertex digraph with all possible $k(k-1)$ arcs. This is tight up to multiplicative constant.
Computing Volumes of Adjacency Polytopes via Draconian Sequences
Authors: Davis Robert , Chen Tianran
Published: April 2022

Adjacency polytopes appear naturally in the study of nonlinear emergent phenomena in complex networks. The ``"PQ-type" adjacency polytope, denoted $\nabla^{\mathrm{PQ}}_G$ and which is the focus of this work, encodes rich combinatorial information about power-flow solutions in sparse power networks that are studied in electric engineering. Of particular importance is the normalized volume of such an adjacency polytope, which provides an upper bound on the number of distinct power-flow solutions.

In this article we show that the problem of computing normalized volumes for $\nabla^{\mathrm{PQ}}_G$ can be rephrased as counting $D(G)$-draconian sequences where $D(G)$ is a certain bipartite graph associated to the network. We prove recurrences for all networks with connectivity at most $1$ and, for $2$-connected graphs under certain restrictions, we give recurrences for subdividing an edge and taking the join of an edge with a new vertex. Together, these recurrences imply a simple, non-recursive formula for the normalized volume of $\nabla^{\mathrm{PQ}}_G$ when $G$ is part of a large class of outerplanar graphs; we conjecture that the formula holds for all outerplanar graphs. Explicit formulas for several other (non-outerplanar) classes are given. Further, we identify several important classes of graphs $G$ which are planar but not outerplanar that are worth additional study.

Published: April 2022

The main purpose of this study was examining the relationship between approaches to learning and academic achievement, the extent to which approaches to learning predict trainees’ academic achievement, and determining gender differences between male and female trainees in approaches to learning and academic achievement in Polytechnic Colleges. Mixed research approach particularly explanatory sequential design was used. Stratified random sampling and purposive sampling were used to select study settings and participants. Data were collected from five Polytechnic Colleges through questionnaire. Population of this study is 372 (183 male and 189 female) trainees. With response rate of 85%, the main analysis was done based on 315 trainees’ (155 male and 160 female) questionnaire responses. Pearson Correlation Coefficient, regression analysis, and independent sample t-test were employed to analyse the collected data. Thus, Pearson correlation coefficient revealed statistically significant positive association of trainees’ academic achievement with approaches to learning (r = .59, r2 = 34.81%, p < .001). Regression analysis results showed that approaches to learning is significant predictors of trainees’ academic achievement in polytechnic colleges. The independent sample t-test analysis results indicated that there is no gender difference between male and female trainees in approaches to learning and academic achievement. On the basis of these findings conclusions and recommendations were made

Some Insights on Chemical Treatment of 3D Printed Parts
Authors: Tamasag Ioan , Amarandei Dumitru , Besliu Irina
Published: April 2022

The substantial increase in the use of the FDM (Fused Deposition Modeling) process for the production of plastic parts in ever wider fields has led to the search for methods to improve the quality of the printed parts. In the case of ABS parts (Acrylonitrile Butadiene Styrene), one of the most common and used methods to improve surface quality is the process of acetone steam treatment, but the application of this method also brings more or less negative effects on the part. The main side effects when applying this method is the low breaking strength and loss of part details on the sharp edges. This paper presents a set of contributions on the relationship between surface quality and the level of detail of parts subjected to acetone steam treatment. In order to analyze the influence of the treatment on the details of the parts, a reverse engineering method was used in which a polyarticular arm FARO Edge 7.5 was used to scan the parts and reconstruct them. The study was performed on parts with 20% infill, grid tipe.
Mechanical Properties of Ultra-high Molecular Weight Polyethylene (tensylon�) from Tensile Tests
Authors: Alil Luminita-Cristina , Arrigoni Michel , Barbu Cristian , Bles guilhem , Deleanu Lorena , Mostovykh Pavel , Sandu Simona M.
Published: April 2022

Results on mechanical properties of Tensylon� composites at room temperature are presented. Single-ply and two-ply samples, obtained from the ply-precursor sheet (of two orthogonal layers) have been subjected to: load till failure in traction, at different strain rates (below 10-1 s-1) and cycles of successive loading and unloading and 5 min stress relaxation period. The characteristic times of relaxation are evaluated and the difference in values of Young modulus before and after the relaxation stage is established. A complex cyclic/relaxation test requires a visco-elasto-plastic model of Tensylon�, and allows to quantify it. This model predicts the material behavior in other types of tests: for instance, it predicts strain rate independence of loading to failure in the considered strain rate range. Cyclic tests fulfilled at a fixed strain rate suggest that Tensylon� is an elastoplastic material without noticeable viscosity. The proposed model, additively including nonlinear viscoelasticity and plastic flow with strengthening, shows a satisfactory agreement with experimental data. It also agrees that the material is strain-rate-insensitive in the range 10-3 s-1-10-1 s-1.

To improve the performance of runway services, it is necessary to increase the capacity of the navigation tools currently owned.
Ethical Resilience Management Framework for Critical Healthcare Information Infrastructure
Authors: Rajamäki Jyri , Hummelholm Aarne
Published: April 2022

The growing complexity of the digital ecosystem in combination with increasing global risks involves various ethical issues associated with cybersecurity and resilience. This paper offers a conceptual resilience governance framework and design aspects for ethical and resilient cyber-physical e-health and e-wellbeing systems. Our safety and security thinking has been based on a supposition that inside defensive walls we are safe. The focus of our actions has been controlling our own systems, improvement of protection, and staying inside the protection. However, nobody can control complex large integrated cyber-physical systems, but on the other hand, coordination and cooperation is a salient point. In e-health and e-wellbeing, this means that the focus is shifting from the control and securing of health and welfare data in a silo to using that data to promote health and wellbeing worldwide in our connected world. On the other hand, we have an ethical need to complement the existing security and risk management knowledge base by developing frameworks and models where we are using, for example, artificial intelligence systems that enable network-wide flexibility and resilience management that strive to maintain and improve critical operations.
Educación artificial

Este trabajo trata sobre el uso de un nuevo termino denominado “educación artifcial”, donde aún no se hace mención en escritos u obras, donde solo aparece tal vez como la aplicación de la inteligencia artifcial al campo educativo. Su objetivo es dar un entendimiento de lo que, con probabilidad, se usará próximamente: la educación artifcial, la cual no es más que la aplicación y la obtención de muchos benefcios de la inteligencia artifcial en la educación; la idea de que una maquina pueda crear curriculas actualizadas en base a las demandas sociales, laborales y sociedades del conocimiento, también de considerar tutores inteligentes para guiar el aprendizaje del alumno, creando rutas de aprendizaje que le permitan aprender de sus errores y dirigiéndolo al éxito de cada actividad. Asimismo, se habla sobre algunos casos prácticos en el mundo de esta tecnologia y cómo se viene desempeñando la labor del docente. A su vez, se realiza una proyección de cómo sería el escenario educativo si consideráramos una inteligencia artifcial avanzada, que reemplace defnitivamente la labor docente y a la persona humana. También hablamos de centros educativos, locales en el hogar, asistidos por una inteligencia artifcial interconectada con otras y empleando herramientas digitales, así como escenarios virtuales asistidos por la realidad virtual y de hardware altamente sofsticado para el procesamiento real de imágenes y de datos actualizados y purgados. Estos sistemas serían alimentados por comunidades de inteligencias artifciales en relación a una disciplina o materia, y así sucesivamente la continuidad y la proyección de lo que se podría lograr es inimaginable; más si cabe ahora con la creación del meta verso, la evolución de la realidad virtual, y el incremento de los dispositivos inmersivos.

Review question / Objective: Does the volume of the upper airway change after an orthodontic intervention? P: growing subjects, adults; I: orthodontic treatment, dentofacial orthopedics, extractions; C: untreated subjects and/or non-extractions; O: volumetric changes of the upper airway measured on CBCT scans. Condition being studied: The primary objective of orthodontic treatment is to establish optimal dental and/or skeletal relationship in harmony with the soft tissue morphology and functioning. In addition, un-impeding or facilitating airway growth and development is an important objective, especially in patients susceptible for airway obstruction or sleep apnea. It is therefore important to look into the effect of various orthodontic treatments on the 3D volumetric changes of the upper airway. Compared with the use of traditional 2D lateral cephalograms, CBCT scans provide the opportunity to perform measurements in more dimensions on the airway with demonstrated reliability. This systematic review therefore includes studies using CBCT scans for evaluation of the airway.

Uluslararası ticaret ve yabancı sermaye yatırımları kapitalizmin çevre ülkelere başlıca yayılma kanallarındandır. Sanayi Devrimi’ni tamamlamış olan İngiltere’nin Kıta Avrupası’nda korumacı dış ticaret politikaları ile karşılaşması onu hammadde ve pazar ihtiyacını karşılayabilmek amacıyla dünyanın diğer bölgelerine sevk etmiştir. Osmanlı Devleti de sahip olduğu zengin doğal kaynaklar ve geliştirilmeye açık ulaşım vasıtaları ile hammadde ve pazar ihtiyacındaki gelişmiş ülkeler için cazip bir yatırım alanı olmuştur. İngiliz sermayedarların Osmanlı topraklarında gerçekleştirdikleri yabancı sermaye yatırımları 1838 sonrası sürecin önemli bir bileşenidir. Özellikle Kırım Savaşı’nı takip eden dönemde İngiltere, Osmanlı Devleti’nde birçok farklı alanda yatırım girişimlerinde bulunmuştur. Bu girişimlerden bir tanesi de Londra’da kurularak Osmanlı Devleti’nin farklı şehirlerinde şubeler açan Şirket-i Maliye-i Mahdûde-i Osmanî’dir. Şirket, Amerikan İç Savaşı süresince uluslararası piyasalarda ortaya çıkan pamuk kıtlığı, fyat artışları ve yüksek karlılık nedeniyle Osmanlı topraklarında pamuk üretimini teşvik etmek amacıyla kurulmuşsa da uzun vadeli bir girişime dönüşememiştir. Bu çalışmada Osmanlı Devleti’nde gerçekleştirilen farklı bir yabancı sermaye girişiminin iktisadi ve tarihsel arka planının detaylandırılması amaçlanmaktadır. Bu bağlamda dönemin arşiv kaynaklarından ve gazetelerden istifade ederek Şirket-i Maliye-i Mahdûde-i Osmanî’nin kuruluşu, faaliyet alanları ve faaliyetlerine neden son verdiği araştırılmaktadır. Çalışmanın bulguları ucu 1866 Paniği’ne uzanan birtakım ilişkileri ortaya koymaktadır.

AbstrakPendidikan Agama Islam merupakan upaya mendidik manusia sesuai dengan ajaran agama Islam sebagai petunjuk dan pedoman hidup seseorang. Pendidikan Agama Islam pada kenyataannya hanya berkutat pada pendidikan yang diselenggarakan oleh institusi atau lembaga pendidikan dari jenjang dasar sampai perguruan tinggi, namun belum menyentuh wilayah-wilayah empirik yang dihadapi oleh masyarakat seperti Skizofrenia. Artikel ini menggunakan design penelitian kepustakaan. Hasil yang diperoleh yakni banyaknya kasus yang terjadi akibat gangguan psikotik ini membuat sejumlah rumah sakit jiwa menerapkan bentuk kegiatan yang bernuansa Pendidikan Agama Islam dalam menangani pasien psikotik skizofrenia, seperti Terapi konseling Islami, Adab Islami, Miliu terapi, berinteraksi dengan sopan dan ramah, serta Pengkajian Islami. Bentuk-bentuk penanganan tersebut telah membuktikan bahwa sebenarnya Pendidikan Agama Islam mencakup wilayah-wilayah kedokteran dan ilmu-ilmu kesehatan yang dalam kenyataannya banyak yang menilai Pendidikan Agama Islam tidak dapat menyentuh wilayah tersebut. Dibutuhkan kajian yang lebih mendalam mengenai peran Pendidikan Agama Islam agar dapat memberikan sumbangsih nyata pada problem-problem yang dihadapi oleh masyarakat.

To create a professional salesperson, enterprises need to provide a guidance, for example, in the form of practical training that can support their works. The ability to adapt when interacting with the customers plays a critical role in relation to improving salesperson performance. However, there are inconsistencies in research findings between adaptive sales and salesperson performance. This research was conducted on salesperson in small and medium enterprises. Our sample consists of 300 respondents who lived in the Special Region of Yogyakarta. To obtain proper data, we carried out screening and trimming. The tests include: bias non-response test, logical connection test, and confirmatory factor analysis. This study uses structural equation model. A Sobel test was conducted to test the role of moderating variable. The findings of the research indicate that niche based relational capability was influenced by customers trust orientation, salesperson’s expertise and adaptability when interacting with their customers. The higher customers trust and the more intelligence of salesperson are, it will increase the niche based relational capability. In addition, salesperson’s performance may increase if it is supported by extensive customers relation based on market gaps, trust and salesperson’s intelligence. This research also discusses managerial implication, limitation and the directions for future research.
