Sentiment to Stocks: Rule-Based and Deep Learning Sentiment Analysis for LSTM-Driven Stock Prediction

How to accurately predict stock prices is a persistent problem in the financial realm. According to behavioral economics, human actions in the stock market tend to be irrational, emotional, and easily misled. In such context, this papers approach involves adopting various sentiment analysis models in subsequent sections of the paper, which aims to synthesize a precise methodology for forecasting stock prices aligned with the available data, namely structured technical analysis, while considering and quantifying investor sentiment, namely unstructured fundamental analysis. This work points out that by adopting sentiment analysis using the VADER and FinBERT models separately, there are accuracy improvements in both integration of VADER or FinBERT and transactional data compared with merely doing stock price prediction by forecasting using historical data alone. This outcome resemble an valuable proposition of modeling and prediction on irrational human behavior. Nevertheless, this paper provides insights on future possible enhancements in this area, which analyzing additional emotional dimensions in textual data and recognizing the multifaceted nature of human emotions is needed.

Conservation Strategies for Aquilaria sinensis: Insights from DNA Barcoding and ISSR Markers.

The evergreen tree species Aquilaria sinensis holds significant economic importance due to its specific medicinal values and increasingmarket demand. However, the unrestricted illegal exploitation of its wild population poses a threat to its survival. This study aims to contribute to the conservation efforts of A. sinensis by constructing a library database of DNA barcodes, including two chloroplast genes (psbA-trnH and matK) and two nuclear genes (ITS and ITS2). Additionally, the genetic diversity and structure were estimated using inter-simple sequence repeats (ISSR) markers. Four barcodes of 57 collections gained 194 sequences, and 1371 polymorphic bands (98.63%) were observed using DNA ISSR fingerprinting. The Nei's gene diversity (H) of A. sinensis at the species level is 0.2132, while the Shannon information index (I) is 0.3128. The analysis of molecular variance revealed a large significant proportion of total genetic variations and differentiation among populations (Gst = 0.4219), despite a relatively gene flow (Nm = 0.6853) among populations, which were divided into two groups by cluster analysis. There was a close genetic relationship among populations with distances of 0.0845 to 0.5555. This study provides evidence of the efficacy and dependability of establishing a DNA barcode database and using ISSR markers to assess the extent of genetic diversity A. sinensis. Preserving the genetic resources through the conservation of existing populations offers a valuable proposition. The effective utilization of these resources will be further deliberated in subsequent breeding endeavors, with the potential to breed agarwood commercial lines.

The power of e-recruitment and employer branding on Indonesian millennials' intention to apply for a job.

Companies need reliable employees to support their business. As e-grocery businesses in Indonesia continue to grow during the pandemic, various strategies are required to attract millennials. This study aims to prove the influence of employer branding, e-recruitment, and post-pandemic employee value proposition (radical flexibility, deeper connection, personal growth, and holistic well-being) in encouraging millennials to apply for jobs at e-grocery companies after the pandemic. Few e-grocery companies in Indonesia use employer branding and e-recruitment; this study attempts to combine these two variables to see the effect of their interaction on influencing greater millennial intentions. Using the latest experimental method, which is the experimental vignette method, we conducted three studies with a total of 619 millennial participants, who were recruited using the convenience sampling technique. All participants received a set of job advertisements as a stimulus. The results showed that e-recruitment could not significantly predict the millennials' intentions when applying for jobs in e-grocery companies. Companies in Indonesia may need to analyze millennials' familiarity with e-recruitment platforms, especially on company websites. However, employer branding successfully predicted millennials' intention to apply for a job in e-grocery companies, which was not affected by the length of their work experience. Employer branding serves as a means of building job seekers' trust through personal promotions. With this trust, job seekers are more motivated to apply to the company. When e-recruitment and employer branding were analyzed simultaneously, there were significant interactive effects on millennials' intentions. Employer branding acted as a socialization medium to introduce e-recruitment and vice versa. E-recruitment served as a form of branding that could shape the perceptions and experiences of millennial job seekers. Lastly, the employee value proposition significantly predicted millennials' intentions, where holistic well-being was the most sought-after value. It can support employees' well-being and encourage them to make valuable propositions that will make e-grocery companies excel in Indonesian labor market.

ROBotic Utility for Surgical Treatment of hernias (ROBUST hernia project)

We describe the evolution in hernia repair approaches in our practice during the first 3 years of adopting robotic assisted laparoscopic surgery. For inguinal hernia repair, we began using the robotic platform for complex hernias, and the use of open repair decreased from 17% to 6%. For primary ventral hernias, open procedures decreased from 59% to 10% and for incisional ventral hernias, from 48% to 11%. Moreover, a large shift in mesh position for ventral hernias was seen, with an increase of the retromuscular position from 20% to 82% and a decrease of intraperitoneal mesh position from 48% to 10%.The robotic platform seems to hold a significant potential for complex inguinal hernias, in addition to ventral and incisional hernias which require component separation. A shorter hospital stay and less postoperative complications might make the adoption of the robotic platform for abdominal wall surgery a valuable proposition.

Does COVID-19 Induced Occupational Stress Moderates the Relationship of Spiritual Motivation and Academicians’ Tacit Knowledge Sharing Behaviour Among South Asian Higher Education Institutions?

The COVID outbreak has frazzled many employers to research how to upkeep and boost the performance outcomes continuously. It is even trickier in Higher Education Institutions (HEIs) when they have hibernated from conventional to cyber universities due to the COVID pandemic. It is relatable to motivate and retain the knowledge workers persistently. Therefore, this study is designed to investigate the impact of academicians' spiritual motivation on their tacit knowledge sharing behaviour, with the moderation of COVID-induced occupational stress. The population embraced the academicians of Pakistani Higher Education Institutions. ~289 academicians were considered as the sample size. Descriptive and inferential statistics (linear regression) were performed in SPSS, whereas; 'Hayes' process macro' was used to test moderation. The findings designate that academicians' spiritual motivation is significantly and positively associated with tacit knowledge sharing behaviour—moreover, COVID-induced occupational stress moderates their relationship. Consequently, the results bequeath the policymakers and the relevant authorities of HEIs, with valuable propositions on how to upkeep academicians' tacit knowledge sharing behaviour by considering COVID-induced occupational stress as eu-stress if they are spiritually motivated. Profuse suggestions were also presented to future researchers to further look into the anticipated study model.

The role of tradition for food and wine producing firms in times of an unprecedented crisis

PurposeThe purpose of the present study is twofold. First, the study will investigate the importance of tradition for businesses operating during the COVID-19 crisis, notably, as a valuable proposition and strategy. Second, the study seeks to advance theoretical understanding, proposing two frameworks based upon emerging dimensions, the resource-based view and dynamic capabilities.Design/methodology/approachAn online survey gathered the views of 107 predominantly micro and small-scale owner-manager and family-owned firms involved in the food and wine sector. These participants are based in Italy, one of the hardest-hit countries in the crisis.FindingsThree fundamental dimensions emerge from the findings. The first, “embedded advantage”, concerns firms' more direct involvement and tradition-related actions. The second, “active advantage”, highlights the already established value of tradition, for example, through firm identity gained, well-established roots and firm culture. The third dimension, “strategic fusion”, underscores the importance of upgrading the business model, where innovation complements tradition strategically.Originality/valueThe study's revealed dimensions provide new conceptual perspectives to understand tradition in the context of firms confronting an unprecedented event. The first proposed theoretical framework illustrates that firms appear to mainly rely on tradition as the fundamental pillar of their overall strategy. Additionally, other firms engage in actions to consolidate tradition's strategic significance, while others embrace innovation to further strengthen their competitiveness. The second framework emphasises relations between these dimensions and key attributes associated with the two adopted theoretical foundations, where the need to “reconfigure tradition” clearly emerges.

Can protection motivation theory explain the perception of international tourists' on medical tourism?

PurposeMedical tourism has grown to become a formidable multinational industry to generate revenue. This phenomenon has also increased impact on the healthcare sector as well as strategies development opportunities. The present study emphases on the international tourists' behavioural intention for medical tourism in Malaysia. A research framework is derived from the exceptional component of fear appeal in protection motivation theory (PMT).Design/methodology/approachData were collected with a sample of 501 respondents and analysed via structural equation modelling approach. Both measurement model and structural model were assessed to generate the result.FindingsThe outcomes have shown a good backing on the use of adapted PMT theoretical model. There is a higher predictive power on health coping than health threats. Coping alternatives can be served as the linkage between the PMT appraisals and behavioural intention.Research limitations/implicationsThe study confirmed the effectiveness of using a theoretical framework in predicting international tourists' behavioural intention for medical tourism. It is suggesting that risk adaptive behaviour does offer a valuable proposition in contributing to the reception of medical tourism.Practical implicationsThe present study argues the need for greater clarity in understanding the emergent implications for health policy and healthcare delivery for future medical tourism development.Originality/valueThe fundamental theories and current literature do not incorporate the component of fear appeal in explaining decision making. The study findings demonstrate that protection motivation theory has provide another promising theoretical model in explaining international tourists' behaviour intention for medical tourism.

Simulation work done with MATLAB software and result helps the efficiency of the proposed technique and confirm that it is 97% efficiency than other ordinary strategies.

Public goods, sustainable development and business accountability

PurposeThe purpose of this paper is to present a linkage between performance measurement at the business level and the concept of public goods usage, and a linkage between the micro- and macro-economic aspects of sustainability.Design/methodology/approachExhibiting the essentials of a public goods cost perspective in order to initiate discussion between statisticians, standard setters for business reporting and practitioners.FindingsShowing what has been achieved in measuring the outcomes of sustainable development efforts and what still needs to be done in order to arrive at aggregate values for national and global commons.Research limitations/implicationsLinking performance measurement at the business level to public goods usage will depend on the co-operation of businesses and national statistics which test the feasibility of monetary indicators for both the micro- and the macro-levels.Practical implicationsFor practitioners in both the statistics profession and management accounting who are concerned with measurement of socioeconomic and environmental phenomena, this attempt at integrating sustainable development indicators and the managerial control system of companies might provide a valuable proposition. It is also a useful contribution to the ongoing debate of the value and credibility of sustainability reporting.Social implicationsIf businesses make no attempts to exhibit numerically how they contribute to preserving and expanding the societal commons, they will be confronted with ever-growing agitation from pressure groups and they might be bypassed in the discussion on the issue of sustainability parameters that those groups are advocating.Originality/valueThis is the first academic paper that demonstrates a reporting model which unites business accounts and national accounts.

The essence of neighbourhood community centres (NCCs) in European sustainable neighbourhoods

This paper analyses an often underestimated and ignored urban design element: the neighbourhood community centre (NCC). The aim is to define, describe and highlight the multidimensional effects that a neighbourhood community centre (NCC) has on a local urban community, and to examine the possible correlation between the level of the NCC’s development and the neighbourhood’s “social urban sustainability” (social cohesion, local identity, sense of place etc.). The main research effort involves exploring and comparing the implementation and development of NCCs in “exemplary urban systems”—the best and most well-known sustainable neighbourhoods in Europe. The final international comparative analysis of NCCs in European sustainable neighbourhoods offers very specific, valuable propositions that can be transferred to future NCCs, with an adaptation to local urban specifics.

Human capital intelligence and economic development

This article explored human capital intelligence and economic development in Zimbabwe with some examples adopted from Israel and many other countries. A qualitative-exploratory literature review methodology was used for the purpose of this study because of its suitability. The primary concern of the author was to have and provide an in-depth analysis and understanding of the multiple realities and truths pertaining to human capital intelligence and economic development in Zimbabwe. An inductive approach was adopted for the purpose of this study. The findings of this article will make it possible to generalise the role of human capital intelligence towards economic development of a country and to develop some valuable propositions for future studies. The findings showed that human capital intelligence plays a critical role in economic development, through laying a foundation for economic development, attracting foreign direct investment, personal remittances, as well as attracting venture capitalists. Empirical evidence from countries such as Israel shows the criticality of human capital intelligence development to economic development of a nation. This article will assist business managers, societal leaders, policymakers, as well as governments to understand the criticality of human capital intelligence towards the development of a company, society and nation at large. This article has, therefore, academic, societal and business value. Keywords: Zimbabwe, economic development, human capital, intelligence, intellectual capital. JEL Classification: O1, J41, O34

Thes “value” and “efficiency” terms in process management

The concepts of value, utility, cost and efficiency in economic theory presenting both the backbone and discussion matter, still do not have a single interpretations, experts continue to argue about the relationships that exist between them. The process management widely uses the terms «valuable proposition», «the process created value», «value chain», «value creating flow». Often it remains unclear what kind of values the authors mean and how to evaluate it. The purpose of the transition to process management is interpreted as elevated efficiency, however, the focus on the quantitative assessment of the efficiency does not guarantee commercial success of the enterprise. The «effectiveness» term has many meanings. There arise a problem how to attach to the terms «value» and «efficiency» a consistent explanation where the applied meaning would not be contrary to the fundamental one , otherwise their use in process management would lead to confusion. The solution of this problem has great practical importance for the business analysts when the company plans to shift to process management. Without it will remain unclear what is the value for the consumer , how it is formed, how to analyze the process, how to discriminate work creating value and cost. Not understanding the nature of business performance, the analyst does not know how it can be controlled. The article shows that the classic process management rather freely uses the terms value and effectiveness, so that in each case one has to understand whichthe ultimate meaning lays in those concepts. It is proposed to separate the phase of business process modeling, where the technological process of production is prepared and which appears to be a key for overall economic impact, since it is exactly this stage where the standard cost-effectiveness of the business is created.

Investigation on production, analytical models, and characteristics of monofilaments/staple fibers composite yarn

This study aims to develop a composite yarn comprising monofilaments/staple fibers with distinctive structures and performance. A modified ring spinning system was proposed for producing the composite yarn with three monofilaments and staple fibers. The spinning mechanism was analytically modeled, and the structures of composite yarn were studied by scanning electron microscopy and optical microscopy. The characteristics of polyester monofilaments/cotton composite yarns and the conventional cotton yarns were compared. Analytical and experimental results showed that three monofilaments were distributed around the yarn center forming a 3D spiral, and the staple fibers interlaced inside and wrapped outside of the composite yarn. Experimental results showed that the composite yarn had better tensile properties, less hairiness, and stronger abrasion resistance. As a result, the composite yarn exhibited a remarkable improvement over the conventional yarn, which could be a valuable proposition for specific purposes, such as offering fabrics with shape preservation based on good yarn’s rigidity, and even electromagnetic shielding effectiveness with metal monofilaments in yarns.

How Can Bourdieu’s Theory of Capital Benefit the Understanding of Advocacy NGOs? Theoretical Framework and Empirical Illustration

This article offers a Bourdieu-inspired organizational analysis of advocacy nongovernmental organizations (NGOs). Pierre Bourdieu’s writings provide valuable propositions for understanding nonprofit advocacy resources that go beyond commonly analyzed economic, human, or social resources. The article describes the relational, accumulative, and transferable nature of Bourdieu’s forms of capital, and connects them to advocacy NGOs. By examining the forms of capital at the disposal of advocacy NGOs involved in the conflict between the State of Israel and the Negev Bedouin, the article empirically illustrates the applicability of Bourdieu’s ideas for the analysis of advocacy resources. The questions addressed are “How are NGOs using the various forms of capital to influence public perceptions and access decision-making forums?” and “What are the implications for nonprofit advocacy research?” Bourdieu’s theory could help nonprofit scholars better understand the prospect and limits of nonprofit advocacy within policy fields.

Diversity measures for one-class classifier ensembles

One-class classification is one of the most challenging topics in contemporary machine learning and not much attention had been paid to the task of creating efficient one-class ensembles. The paper deals with the problem of designing combined recognition system based on the pools of individual one-class classifiers. We propose the new model dedicated to the one-class classification and introduce novel diversity measures dedicated to it. The proposed model of an one class classifier committee may be used for single-class and multi-class classification tasks. The proposed measures and classification models were evaluated on the basis of computer experiments which were carried out on diverse set of benchmark datasets. Their results confirm that introducing diversity measures dedicated to one-class ensembles is a worthwhile research direction and prove that the proposed models are valuable propositions which can outperform the traditional methods for one-class classification.

Carbonate Direct Fuel Cell Operation on Dual Fuel

ABSTRACT The ability to operate highly-efficient, pollution-free, distributed generation power plants on either natural gas or HD-5 grade propane is of interest to the U.S. Army and the U.S Department of Homeland Security as secure power source for critical power operations. The ability to operate continuously on HD-5 propane also provides a valuable proposition to islands, remote sites, national parks, data centers, military bases, hotels, and hospitals. HD-5 propane, as opposed to other grades of propane, was selected as the back-up fuel of choice because of its availability (even in remote areas), cost, and ease of processing in the fuel cell power plant. Although natural gas distribution through utility pipelines is convenient, it is vulnerable to natural disaster, threats of terrorism, and simple repair outages. Propane, however, is routinely transported and stored as a liquid at ambient temperatures and offers a convenient and secure option for fuel cell operations. An adequate quantity of propane c...

Leslie Marmon Silko's Ceremony: Healing Ethnic Hatred by Mixed-Breed Laughter

In Ceremony, Leslie Silko brilliantly crosses racial styles of humor in order to cure foolish delusions readers may have, if we think we are superior to Indians or inferior to whites, or perhaps superior to whites or inferior to Indians. Silko plays off affectionate Pueblo humor against black humor so prominent in 20th-century white culture. This comic strategy has end-result of opening our eyes to our general foolishness, and also to possibility of combining merits of all races. Joseph Campbell wrote in The Inner Reaches of Outer Space of change in mythologies away from local and tribal toward a mythology that will arise from unified earth as of one harmonious being (16-17). Ceremony is a work that changes local mythologies in that more inclusive spirit. Silko is right person to have written this book. She herself is a mixed-blood, and her experience has evidently given her access not only to a variety of problems, but also to a variety of styles of clowning and joking. Although Elaine Jahner has mentioned presence of jokes in novel (39), I have known whites to read Ceremony as not comical at any point. Probably their power of recognition had been switched off by the picture of humorless Indian ... so common in so much of literature, in so many of film and television depictions of Native Americans (Bruchac 22). Although Ceremony is serious, offering a number of valuable propositions for our consideration, narrative also spins a web of jokes in morning sun. If readers' cultural background has not prepared them for Pueblo reverence for maternal spider, they could think of Silko's writing as resembling turning and darting of a brown-and-white bird hunting insects in air, at one moment flashing white sunlight, next nearly invisible against browns of this beautiful Earth.
