Pairs trading has been a successful tool for traders since its inception in the 1980s and has evolved significantly with the introduction of algorithmic, machine, and AI trading. This evolution has compli­cated the implementation of this strategy that traditionally benefits institutional or specialized investors. Despite this, the simplicity of pairs trading remains accessible, indicating potential benefits for ordinary traders. By focusing on the strategy’s fundamental principles and employing a real-time market test on a popular trading platform, the study aims to reveal its applicability and efficacy for short-term equity trading. Utilizing basic trading platform tools and Excel functions, the research aims to demonstrate a simplified approach to pairs trading. The findings will provide insights into the strategy’s effectiveness, providing non-expert traders with a viable approach to navigate today’s volatile markets through a simplified yet effective pairs trading model. The experiment’s findings highlight varying performances across different stock pairs, with notable differences in volatility. While five out of 11 pairs achieved positive returns, only two met the closure criteria within the short-term horizon, suggesting that a longer trading period and a more diversified pair’s portfolio may be necessary to fully capture expected price convergence.

In this paper, we tackle a bi-objective optimization problem in which we aim to maximize the portfolio diversification and, at the same time, minimize the portfolio volatility, where the ESG (Environmental, Social, and Governance) information is incorporated. More specifically, we extend the standard portfolio volatility framework based on the financial aspects to a new paradigm where the sustainable credits are taken into account. In the portfolio’s construction, we consider the classical constraints concerning budget and box requirements. To deal with these new asset allocation models, in this paper, we develop an improved Multi-Objective Particle Swarm Optimizer (MOPSO) embedded with ad hoc repair and projection operators to satisfy the constraints. Moreover, we implement a deep learning architecture to improve the quality of estimating the portfolio diversification objective. Finally, we conduct empirical tests on datasets from three different countries’ markets to illustrate the effectiveness of the proposed strategies, accounting for various levels of ESG volatility.

Background: Communication is important for everyone, including individuals with hearing and speech impairments. For this demographic, sign language is widely used as the primary medium of communication with others who share similar conditions or with hearing individuals who understand sign language. However, communication difficulties arise when individuals with these impairments attempt to interact with those who do not understand sign language. Objective: This research aims to develop models capable of recognizing sign language movements in Bahasa and converting the detected gesture into corresponding words, with a focus on vocabularies related to religious activities. Specifically, the research examined dynamic sign language in Bahasa, which comprised gestures requiring motion for proper demonstration. Methods: In accordance with the research objective, sign language recognition model was developed using MediaPipe-assisted extraction process. Recognition of dynamic sign language in Bahasa was achieved through the application of Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) methods. Results: Sign language recognition model developed using bidirectional LSTM showed the best result with a testing accuracy of 100%. However, the best result for the CNN alone was 86.67 %. The integration of CNN and LSTM was observed to improve performance than CNN alone, with the best CNN-LSTM model achieving an accuracy of 95.24%. Conclusion: The bidirectional LSTM model outperformed the unidirectional LSTM by capturing richer temporal information, with a specific consideration of both past and future time steps. Based on the observations made, CNN alone could not match the effectiveness of the Bidirectional LSTM, but a combination of CNN with LSTM produced better results. It is also important to state that normalized landmark data was found to significantly improve accuracy. Accuracy within this context was also influenced by shot type variability and specific landmark coordinates. Furthermore, the dataset containing straight-shot videos with x and y coordinates provided more accurate results, dissimilar to those comprised of videos with shot variation, which typically require x, y, and z coordinates for optimal accuracy.

The recent 2020 global pandemic necessitated changes in various sectors, including economic, business, and academic landscapes. In response to the escalating COVID-19 cases, national governments worldwide implemented stringent measures, including movement control policies and the adoption of innovative educational practices. This study focused on the transition of Philippine educational institution from face-to-face to remote, blended, modular, and online learning modalities. The study looked into the effects of online learning, particularly its potential to enhance students' academic performance through the development of computer and information literacy (CIL), self-directed learning (SDL), and motivation for learning (MOL) levels. The study specifically investigated the challenges faced by students and teachers in selected schools in South Manila City, Philippines, focusing on technological services, time management, and learning approaches.   Identified challenges namely technological services, time management, and learning approaches were operationally used as study variables to assess the impact of these challenges on operational school support in the context of full online learning modalities. Findings showed operational school support is significantly associated with the challenges encountered by students during full online learning.  A significant difference was reported between operational school support and technological services provided to the students during full online learning modality. Also, there was a difference in the student time management and student learning approaches

A adoção de boas práticas de governança auxilia na assimetria informacional, enaltece a imagem da empresa no mercado, bem como a competitividade, auxiliando no crescimento e evolução do desempenho. Diante disso esse estudo objetiva analisar a influência das práticas de governança corporativa e da auditoria no desempenho das companhias abertas listadas na B3. Trata-se de pesquisa descritiva, com análise documental e abordagem quantitativa. A amostra da pesquisa compreendeu as companhias abertas listadas na B3, no período de 2011 a 2017. Para o tratamento dos dados utilizou-se de regressão linear. Constatou-se que o “Percentual de membros independentes no Conselho de Administração” influência de forma inversa no indicador ROA, ou seja, quanto maior o percentual, menor o ROA. O mesmo resultado também se repetiu com o indicador ROE. Quanto ao MTB e Q de Tobin, o nível diferenciado de governança e maiores percentuais de membros independentes influenciam os indicadores, ou seja, quanto mais práticas de governança implementadas nas organizações, melhor a percepção dos indicadores MTB e Q de Tobin. Os resultados confirmam que as boas práticas de Governança, incluindo a constituição de comitês de auditoria externa influenciam no desempenho das firmas. Dessa forma, o estudo se justifica, pois, além de oferecer informações relevantes aos gestores, reguladores, analistas e stakeholders permite o olhar sob a luz da Teoria da Agência, a qual sugere que diretores independentes no Conselho de Administração e nos Comitês de Auditoria fornecem monitoramento efetivo da administração, e que a governança corporativa é capaz de melhorar o desempenho das organizações.

Tondok Bakaru Village in Mamasa Regency was designated as a Desa Sadar Wisata in 2019, as an effort to increase the local economy. The purpose of this study to determine the perceptions and motivations of stakeholders towards the development of Tondok Bakaru ecotourism. The phenomenological approach is used to analyze correlations between the proposed development with the economic development, ecology, and socio-culture. Study results are classified based on class intervals listed on the assessment graphs completed with associated descriptions. Notable findings here are as follows. Stakeholder's perception of Tondok Bakaru ecotourism development is on a ‘very agreeable’ scale. This is due to a ‘high desire’ scale expressed by stakeholders to have active roles in the development of ecotourism in Mamasa. Stakeholder motivation towards economic development is also on a ‘high scale’. Many stakeholders also express that it is necessary to improve tourism infrastructures, provide support for orchid cultivation-related business, development of networks for food provision, and other supporting facilities. Aspiration for the development of ecology-based tourism is also on a rather ‘high’ scale, as the concept of Tondok Bakaru ecotourism has not been well-conceived that indeed has disrupted the hydrological system, land conservation, and preservation of flora and fauna. Moreover, aspiration for socio-cultural development is on a ‘very high’ scale. This is influenced by a great concern on the gradual extinction of Tondok Bakaru Village’s socio-cultural assets. Keywords: ecology; economy; ecotourism; stakeholder; socio-culture   Abstrak Desa Tondok Bakaru di Kabupaten Mamasa ditetapkan menjadi Desa Sadar Wisata pada tahun 2019 sebagai upaya peningkatan daya tahan ekonomi lokal. Tujuan penelitian ini adalah untuk mengetahui persepsi dan motivasi pemangku kepentingan terhadap pengembangan ekowisata Tondok Bakaru. Pendekatan fenomenologi digunakan untuk menganalisis persepsi dan motivasi terhadap pengembangan ekowisata yang berkaitan dengan ekonomi, ekologi dan sosial budaya di Tondok Bakaru. Hasil analisis dikelaskan berdasarkan interval kelas pada grafik penilaian dan pemaknaannya diuraikan secara deskriptif kualitatif. Persepsi terhadap pengembangan ekowisata Tondok Bakaru berada pada skala sangat setuju karena didasari oleh adanya keinginan yang tinggi dari pemangku kepentingan untuk berperan aktif pada pengembangan ekowisata di Kabupaten Mamasa. Motivasi pemangku kepentingan terhadap pengembangan ekonomi berada pada skala tinggi. Terbatasnya penunjang ekonomi ekowisata sehingga perlu dilakukan pembenahan infrastruktur, pengadaan inkubasi kelompok usaha budidaya tanaman anggrek, makanan dan penyewaan fasilitas penunjang. Motivasi pada pengembangan ekologi ekowisata pada skala agak tinggi karena konsep pengembangan ekowisata Tondok Bakaru belum tertata dengan baik yang memungkinkan terganggunya sistem hidrologi, konservasi lahan dan  pelestarian flora fauna. Motivasi pada pengembangan sosial budaya berada pada skala sangat tinggi karena dipengaruhi oleh keprihatinan pada asset sosial budaya yang saat ini terancam punah. Kata kunci: ekologi, ekonomi; ekowisata; eemangku kepentingan; eosial budaya

The study aims to investigate the effect of conventional capital ratio, risk-based capital ratio, and capital buffer ratio on commercial bank risk-taking over the period from 2002 to 2019 using a two-step GMM method. The finding reveals that there is a positive relationship between traditional capital ratio and risk-taking for the full sample results, which is supported by the regulatory hypothesis. The results are same across various categories based on capitalization and liquidity. Whereas the relationship is negative when capital is measured through risk-based capital ratio and capital buffer, the results are in line with the moral hazard hypothesis. The outcomes are consistent for all subcategories other than for well-capitalized and low liquid banks. The full sample findings are consistent when risk is proxied through loan loss provision. The impact of capital ratios on risk-taking in the pre-, pro- and post-crisis eras is heterogeneous and ‎significant. The findings have significant insights for regulators to observe the differences among pre-, pro- and post-crisis periods for the well, adequately, under, significantly under-capitalized, high and low liquid insured commercial banks of the USA.

Urban agriculture offers the opportunity to provide fresh, local food to urban communities. However, urban agriculture can only be successfully embedded in urban areas if consumers perceive urban farming positively and accept urban farms in their community. Success of urban agriculture is rooted in positive perception of those living close by, and the perception strongly affects acceptance of farming within individuals' direct proximity. This research investigates perception and acceptance of urban agriculture through a qualitative, exploratory field study with N = 19 residents from a major metropolitan area in the southwest U.S. Specifically, in this exploratory research we implement the method of concept mapping testing its use in the field of Agroecology and Ecosystem Services. In the concept mapping procedure, respondents are free to write down all the associations that come to mind when presented with a stimulus, such as, “urban farming.” When applying concept mapping, participants are asked to recall associations and then directly link them to each other displaying their knowledge structure, i.e., perception. Data were analyzed using content analysis and semantic network analysis. Consumers' perception of urban farming is related to the following categories: environment, society, economy, and food and attributes. The number of positive associations is much higher than the number of negative associations signaling that consumers would be likely to accept farming close to where they live. Furthermore, our findings show that individuals' perceptions can differ greatly in terms of what they associate with urban farming and how they evaluate it. While some only think of a few things, others have well-developed knowledge structures. Overall, investigating consumers' perception helps designing strategies for the successful adoption of urban farming.

Este trabalho se propôs a analisar a efetividade do Projeto de Lei do Senado - PLS nº 116/2017 como instrumento para mensurar a eficiência no serviço público, utilizando-se, para tanto, como parâmetro para inferência a comparabilidade da atual avaliação de desempenho para progressão das IFES. Para alcançar este objetivo, realizou-se uma pesquisa de campo na UFRPE através de questionários online (GoogleDocs) com os gestores e buscou-se na literatura, pesquisas em relação a avaliação de desempenho em instituições de ensino para comparação. Dessa forma, evidenciou-se que, apesar da criação de instrumentos capazes de auxiliar na busca pela eficiência, ainda há forte presença do clientelismo e corporativismo no serviço público, trazendo como resultado a falta de efetividade das ferramentas atuais que visam medir a eficiência dos servidores, levando os gestores a inferirem que ocorrerá o mesmo com a avaliação proposta no Projeto de Lei do Senado. Conclui-se, portanto, que são necessários novos mecanismos organizacionais para a obtenção da eficiência no serviço público, pois algumas práticas impessoais ainda estão enraizadas na gestão pública, não permitindo que a avaliação de desempenho se torne capaz de modificar a cultura organizacional vigente. Palavras chave: Avaliação de desempenho; Eficiência; Projeto de Lei do Senado nº 116/2017

Revolusi industri 4.0 dan persaingan bisnis yang semakin ketat menjadikan TI sebagai pendukung dalam pencapaian tujuan bisnis utama sebuah perusahaan. Salah satu bentuk dukungan TI dalam organisasi adalah penggunaan perangkat lunak Enterprise Resource Planning (ERP) dalam pengelolaan sumber daya perusahaan. Akan tetapi, dalam banyak kasus implementasi SAP tidak selalu membawa dampak sesuai dengan ekspektasi perusahaan. Hal ini disebabkan SAP menggunakan best practice yang belum tentu memiliki tingkat kesesuaian dengan proses bisnis perusahaan. Sehingga terdapat kesenjangan (gap) antara proses bisnis perusahaan yang digunakan sebagai acuan best practice oleh SAP dan perusahaan yang akan mengimplementasikan sistem ERP. Penelitian ini bertujuan untuk menyusun dokumen pemodelan proses bisnis as-is dan to-be serta mengidentifikasi kesenjangan antara proses bisnis yang sedang berjalan saat ini dengan proses bisnis pada best practice SAP khususnya pada modul Human Capital Management, salah satu modul utama SAP yang memainkan peran penting dalam membangun manajemen sumber daya yang baik di perusahaan. Hasil analisis kesenjangan memperlihatkan perubahan apa saja yang terjadi pada komponen proses bisnis, baik dari sisi aktivitas, sumber daya yang terlibat, kebutuhan kebijakan, dan struktur organisasi. Perubahan yang terjadi karena penerapan SAP sebagai sistem informasi SDM tentunya membawa dampak. Dampak yang diperoleh dari penerapan teknologi biasa disebut dengan nilai (value). Nilai tersebut berupa manfaat yang mengacu kepada peningkatan efisiensi proses kerja yang diterapkan dalam organisasi. Abstract Industrial revolution 4.0 and increasingly fierce business competition make IT as main supporter in achieving the main business objectives of an enterprise. One form of IT support within organizations is the use of Enterprise Resource Planning (ERP) software in enterprise resource management. However, the result of many SAP implementation cases do not always in line with the company expectations. This is because SAP used best practices that do not have the same level of compatibility with the company's business processes. Hence, there is a gap between the company's business processes used as the best practice reference by SAP and the company that will implement the ERP system. This study aims to establish as-is and to-be business process modeling documents and identify the gaps between current business processes of the organization and business processes in SAP best practices especially in the Human Capital Management module, one of SAP's main modules that plays an important role in building good resource management in the company. The gap analysis results show what changes occur in the business processes components in terms of activity, the resources involved, policy requirements, and organizational structure. These changes certainly would have some impacts. The impacts is usually called as value. This value is in the form of benefits that refer to an increase in the efficiency of work processes applied in the organization

After these years of implementation of the Bologna process for the adaptation to the European higher education area in the current context, it is necessary to review how certain disciplines have strengthened their position in society. In this paper, we will focus on the evolution of the degree of pedagogy, as well as professional profile which plays, from the perspective of the protagonists themselves, the students, since they will be professionals who carry out their work in the immediate future in the society, and will implement those acquired skills, being responsible for transmitting this legacy. For this reason it is necessary of this research, coupled with the fact that around the definition of pedagogy, there is ambiguity and lack of knowledge regarding their functions and areas of professional activity. This study will allow having a vision contextualized on different working routes that this profession can carry out, in order to draw conclusions about its academic profile and therefore socio-labour, favoring an improvement of the image social of the pedagogue, which make it possible to reduce the uncertainty regarding this professional. The methodology used was descriptive and quantitative, with a non-experimental design by survey method. It shows total 334 students, belonging to the degree of pedagogy of the University of Granada, enrolled in the academic year 20162017. The results show that the figure of the pedagogue is a multidisciplinary professional who can cover different fields of action and not just linked to the field of education, but provides an opening to the business context. For this reason, the training (formal, non-formal, and business), is a basic pillar in our society. That is, where the importance of the figure of the pedagogue resides, and how it should position itself as the expert in these subjects.

Objective: The goal of this article is to study the relationship between innovations and exporting of Chinese firms and identify which type of innovation contributes most to the probability of exporting. Research Design & Methods: We refer to the recent strand in the new trade theory literature that stresses the importance of firm productivity in entering export markets. We distinguish between product, process and managerial innovations that can increase productivity. The empirical investigation is based on the probit model and the firm-level data set covering two years: 2003 and 2012. Findings: Our empirical results show that the probability of exporting is positively related to product and process innovations, firm size, foreign capital participation and foreign technology. Moreover, we find that in 2003 process innovations were more important for export performance than product innovations, while in 2012 it was the opposite. Implications & Recommendations: Firms should coordinate their strategic assets and resources for innovation in order to enhance their overall level of competitiveness. Governments should work on establishing stronger institutional environment necessary to provide firms with protection of intellectual property rights, an easier access to financing of innovation, a lower tax burden upon innovative firms, the higher quality of human resources to firms and more supportive policy packages. Contribution & Value Added: In contrast to previous that used only the R&D spending as the measure of innovation in our study we also use innovation outcomes. In particular, we determine which innovation type is of greatest importance, having controlled for the set of other firm characteristics.

El presente estudio se centra en el análisis de la literatura contemporánea cuya formalidad textual se forja, tanto estructural como, en cierto modo, temáticamente, a partir de los fundamentos elementales de la tragedia griega clásica. Para ello tomaremos el ejemplo de la obra del dramaturgo libanés Wajdi Mouawad, Incendios, donde entremezcla tintes autobiográficos con fuentes de la tragedia griega clásica, siendo más evidente la de Edipo Rey es decir, la relación entre la madre y el hijo y el descubrimiento de la Verdad, que ya aparece en la Poética de Aristóteles. También encontramos el caso de Cadmo y la búsqueda de un familiar raptado y la importancia del aprendizaje del lenguaje para entender los acontecimientos que suceden.

Despite ‘pendulum swings’ and ‘revolutions’ throughout the history of language teaching, the association of errors and grammar (of one’s native language or of a second/foreign language) has been a constant concern of language professionals as well as the subject of academic interest in linguistics, second language acquisition and grammaticology. Grammar books are ideally suited to the investigation of how perceptions about errors, along with associated notions such as those of grammaticality, acceptability and correctness, have changed throughout the centuries. While much academic interest has been devoted to the analysis of English pedagogical grammar books (and usage manuals) aimed at native speakers (‘prescriptive’ grammar books and usage manuals, cf. Peters 2006), very little is known about English pedagogical grammar books for non-native speakers, particularly those published in the 20th and 21st centuries. A recent development within the realm of pedagogical grammaticography has been the genre of pedagogical grammar books specifically aimed at teachers of English as a second or foreign language (Nava 2008). Grammar books such as Celce Murcia and Larsen Freeman (1999) have the express purpose of presenting English grammar drawing on research in linguistics and second language acquisition that is thought to be relevant to the practical business of teaching grammar to second/foreign language learners. In this contribution, after identifying a few key issues in the way the notion of ‘error’ has been conceived of in linguistics, second language acquisition and grammar writing, I will present a study of how a selection of pedagogical grammar books for English language teachers view and operationalize errors.
