In the manufacture of Republic aircraft the use of forged parts has increased from one 12 × 12 in. component in the P47 Thunderbolt to a total of 436 forged units in recent designs.

Most studies on Sentiment Analysis are performed in English. However, as the third most spoken language on the Internet, Sentiment Analysis for Spanish presents its challenges from a semantic and syntactic point of view. This review presents a scope of the recent advances in this area.

A systematic literature review on Sentiment Analysis for the Spanish language was conducted on recognized databases by the research community.

Results show classification systems through three different approaches: Lexicon based, Machine Learning based and hybrid approaches. Additionally, different linguistic resources as Lexicon or corpus explicitly developed for the Spanish language were found.

This study provides academics and professionals, a review of advances in Sentiment Analysis for the Spanish language. Most reviews on Sentiment Analysis are for English, and other languages such as Chinese or Arabic, but no updated reviews were found for Spanish.

In Digging into Data 3 (DID3) (2014-2016), ten funders from four countries (the USA, Canada, the UK, and the Netherlands) granted $5.1 million to 14 project teams to pursue data-intensive, interdisciplinary, and international digital humanities (DH) research. The purpose of this paper is to employ the DID3 projects as a case study to explore the following research question: what roles do librarians and archivists take on in data-intensive, interdisciplinary, and international DH projects?

Participation was secured from 53 persons representing eleven projects. The study was conducted in the naturalistic paradigm. It is a qualitative case study involving snowball sampling, semi-structured interviews, and grounded analysis.

Librarians or archivists were involved officially in 3 of the 11 projects (27.3 percent). Perhaps more importantly, information professionals played vital unofficial roles in these projects, namely as consultants and liaisons and also as technical support. Information and library science (ILS) expertise helped DID3 researchers with issues such as visualization, rights management, and user testing. DID3 participants also suggested ways in which librarians and archivists might further support DH projects, concentrating on three key areas: curation, outreach, and ILS education. Finally, six directions for future research are suggested.

Much untapped potential exists for librarians and archivists to collaborate with DH scholars; a gap exists between researcher awareness and information professionals’ capacity.

This qualitative research explores the relationship between religiosity, suicide thoughts and drug abuse among 55 homeless people, interviewed with interpretative phenomenological analysis. Analyzing the thematic structure of the participants' narrations, important main themes appeared in order to avoid suicide, among which family, the certainty of finding a solution and the will to live. However, the suicide ideation inheres in about 30% of participants, almost all believers, addicted and/or alcoholics. Results suggest that religiosity and meaning of death neither prevent from substances abuse and alcoholism, nor is a protective factor against suicide ideation. Meanings of life are the most important reasons for living, and when they are definitively considered unworkable, alcohol and drug help to endure life in the street. A specific model is discussed.

Nigeria has been ravaged by terrorist activities which has made the country unsafe for Nigerians and foreign investors. The motivation of this study arises from the dearth of research applying quantitative empirics to the determinants of terrorism in a specific country. To achieve this goal, vector autoregressive (VAR) model was applied using data from Global Terrorism Database (GTD), International Country Risk Guide (ICRG) data, Stockholm International Peace Research Institute (SIPRI) data, and Transparency International. Stata 13 software was used for estimation. The results show that ethnic violence, absence of good governance, presence of corruption, and rises in military expenditure are part of the causes of terrorism in Nigeria. It is, therefore, recommended that internal security should be maintained to minimize the occurrence of ethnic violence and ethnoreligious biases (sentiments) in the discussion of issues concerning Nigeria. Also, politicians should stop the proliferation of arms, as this will cease the violent reactions before and after elections. Finding lasting solutions to corruption using constitutional means will improve the quality of governance, which will improve the welfare state of the people and reduce restiveness.

The purpose of the work is to study the process of development of “conflict-free” socio-economic system from the positions of the theory of conflicts and the theory of systems.

The object of the research is development of systems according to the optimistic scenario from the positions of the theory of systems and development of “conflict-free” socio-economic system from the positions of the theory of conflicts. The methods include comparative analysis, dynamic modeling of systems, and formalization. The authors compare treatment of phenomena and processes that emerge during development of system from the positions of the theory of systems and the theory of conflicts and compare the model of development of “conflict-free” socio-economic system from the positions of the theory of conflicts and the theory of systems.

As a result of the research, due to founding on the theory of systems, the theory of economic conflicts receives meta-scientific conceptual and methodological substantiation, which ensures its advantages as compared to the existing theory of economic cycles and the existing theory of economic crises: complex consideration of economic and social effects of conflict, correct description of phases of conflict, and more precise classification of causes of conflicts.

Due to these advantages, the theory of economic conflicts may help to describe, model, and forecast the processes of development of modern socio-economic systems, as well as to classify them via differentiating “conflict” and “non-conflict” systems.

The relationship between terrorism and foreign direct investment (FDI) has stimulated research curiosity given its effects on lives lost, injuries, property damaged, and the psychological aftereffects, which to a very large extent impact economic growth and development. The realization of the magnitude of its influence on bilateral economic ties engineered the study, which examined the impact of terrorism on FDI in Nigeria. The data for this study were sourced from Global Terrorism Index (GTI), Stockholm International Peace Research Institute (SIPRI) database, International Country Risk Guide (ICRG)’s Quality of Governance (QoG) database, Central Bank of Nigeria (CBN) Bulletin, and World Bank Development Indicators (WDI) using autoregressive distributive lag (ARDL) bounds testing approach as described by Pesaran et al. (2001). From the results obtained, military expenditure, episode(s) of ethnic violence, and terrorist attacks have all been noted to have negative and significant impacts on FDI in Nigeria. The implication is that the reduction in FDI observed in the data is attributed to terrorism. Therefore, governments should overhaul the security apparatus so as to quell the menace of terrorists. This will go a long way to create a conducive environment for FDI to thrive, which will create more jobs for the growth and development of the Nigerian economy.

Because of chronic financial crises experienced during past several decades repeatedly and a failure to protect investors’ rights as a result, the world is looking for an alternative form of stock market for quite some time so that interests of all relevant stakeholders can be safeguarded. At the same time, from the perspectives of devout Muslims, the current form of stock market restricts a Muslim to make investments in the market because of several unsatisfying provisions from the viewpoint of the Islamic law known as Shariah. This study aims to provide the criteria under which conditions of the Islamic Shariah permit making investments in the stock market. Hand in hand with that primary discussion, it has been eluded briefly why the Islamic Shariah principles offer a better alternative against conventional practices of the stock market.

This is a descriptive study based on the literature review.

This study explores the basic Islamic principles of investment in the stock market by revisiting the norms laid down by Shariah and current global practices of Islamic stock market and indexes.

This study will work as a guideline for investors and market authorities to understand the original Shariah rulings and the benchmark rulings for investment or establishing full-fledged Islamic stock markets, indexes and mutual funds.
