Abstract

Purpose

This chapter presents a discussion and an analysis of the literature on nationalization of international business. National governments have justified the expropriation and nationalization of the operations of foreign multinational in their jurisdiction based on the social responsibilities as welfare providers, and safeguarding the short- and long-term interest of their citizens.

Methodology/approach

There are multiple studies that show the processes and impacts of nationalizations and privatizations (also called denationalizations) worldwide. This chapter analyses specific cases to the light of existing international business literature and proposes prepositions for future studies.

Findings

This chapter presents an analysis where theories of internationalization could be used to analyze specific advantages of States and domestic investors when assuming ownership of operations of international business in their national territory.

Originality/value

The context, processes, and consequences of nationalization of foreign firms historically, economically, and politically have generally a correlation either with political changes, and macroeconomic scenarios related to scarcity and uncertainty in the international market of extractive industries, or with nationalistic political views in national governments.

Abstract

Eighty‐five participants attended the 4th ISHM Display meeting at the Jaarbeurs Congress Centre in Utrecht on 16 October, 1986. The programme of the day started with the annual general membership meeting of the Benelux Chapter. The chairman, Mr T. Kwikkers, gave a short review of the state of affairs of ISHM‐Benelux and of the activities of the last year. He mentioned the temporary enlargement of the executive committee to give a new generation a chance to gain experience in the ISHM organisation and to take up some new activities. In order to raise publicity for ISHM and Hybrid Circuits a new brochure has been designed and a set of material for demonstration purposes was collected. With the material every member of the chapter can easily set up a presentation for schools or customers. This year ISHM‐Benelux has grown from 85 to 100 members and enjoys a healthy financial situation. Next year again emphasis will be put on public relations. Professor R. Govaerts signified that he was no longer available for a position in the executive committee. As Prof. Govaerts has been very active and stimulating for the ISHM‐Benelux Chapter from its foundation in 1976 up to now, the general membership meeting decided to appoint him as (the first) honorary member of this chapter. Except for Professor Govaerts, the sitting executive committee, consisting of 15 members, was re‐elected for another year. After the European conferences in Bournemouth and Hamburg the ISHM‐Benelux chapter is asked to organise the 1991 Conference. The executive committee is already looking out for candidates for a function in the organising committee, which must be formed in the coming year.

Abstract

Purpose

The purpose of this paper is to initially perform Senti-WordNet (SWN)- and point wise mutual information (PMI)-based polarity computation and based polarity updation. When the SWN polarity and polarity mismatched, the vote flipping algorithm (VFA) is employed.

Design/methodology/approach

Recently, in domains like social media(SM), healthcare, hotel, car, product data, etc., research on sentiment analysis (SA) has massively increased. In addition, there is no approach for analyzing the positive or negative orientations of every single aspect in a document (a tweet, a review, as well as a piece of news, among others). For SA as well as polarity classification, several researchers have used SWN as a lexical resource. Nevertheless, these lexicons show lower-level performance for sentiment classification (SC) than domain-specific lexicons (DSL). Likewise, in some scenarios, the same term is utilized differently between domain and general knowledge lexicons. While concerning different domains, most words have one sentiment class in SWN, and in the annotated data set, their occurrence signifies a strong inclination with the other sentiment class. Hence, this paper chiefly concentrates on the drawbacks of adapting domain-dependent sentiment lexicon (DDSL) from a collection of labeled user reviews and domain-independent lexicon (DIL) for proposing a framework centered on the information theory that could predict the correct polarity of the words (positive, neutral and negative). The proposed work initially performs SWN- and PMI-based polarity computation and based polarity updation. When the SWN polarity and polarity mismatched, the vote flipping algorithm (VFA) is employed. Finally, the predicted polarity is inputted to the mtf-idf-based SVM-NN classifier for the SC of reviews. The outcomes are examined and contrasted to the other existing techniques to verify that the proposed work has predicted the class of the reviews more effectually for different datasets.

Findings

There is no approach for analyzing the positive or negative orientations of every single aspect in a document (a tweet, a review, as well as a piece of news, among others). For SA as well as polarity classification, several researchers have used SWN as a lexical resource. Nevertheless, these lexicons show lower-level performance for sentiment classification (SC) than domain-specific lexicons (DSL). Likewise, in some scenarios, the same term is utilized differently between domain and general knowledge lexicons. While concerning different domains, most words have one sentiment class in SWN, and in the annotated data set their occurrence signifies a strong inclination with the other sentiment class.

Originality/value

The proposed work initially performs SWN- and PMI-based polarity computation, and based polarity updation. When the SWN polarity and polarity mismatched, the vote flipping algorithm (VFA) is employed.

Abstract

Purpose

Natural languages have a fundamental quality of suppleness that makes it possible to present a single idea in plenty of different ways. This feature is often exploited in the academic world, leading to the theft of work referred to as plagiarism. Many approaches have been put forward to detect such cases based on various text features and grammatical structures of languages. However, there is a huge scope of improvement for detecting intelligent plagiarism.

Design/methodology/approach

To realize this, the paper introduces a hybrid model to detect intelligent plagiarism by breaking the entire process into three stages: (1) clustering, (2) vector formulation in each cluster based on semantic roles, normalization and similarity index calculation and (3) Summary generation using encoder-decoder. An effective weighing scheme has been introduced to select terms used to build vectors based on K-means, which is calculated on the synonym set for the said term. If the value calculated in the last stage lies above a predefined threshold, only then the next semantic argument is analyzed. When the similarity score for two documents is beyond the threshold, a short summary for plagiarized documents is created.

Findings

Experimental results show that this method is able to detect connotation and concealment used in idea plagiarism besides detecting literal plagiarism.

Originality/value

The proposed model can help academics stay updated by providing summaries of relevant articles. It would eliminate the practice of plagiarism infesting the academic community at an unprecedented pace. The model will also accelerate the process of reviewing academic documents, aiding in the speedy publishing of research articles.

Abstract

Purpose

The critical Mach number, lift-to-drag ratio and drag force play important role in the performance of the wings. This paper aims to investigate the effect of taper stacking, which has been used to generalize wing sweeping, on those parameters.

Design/methodology/approach

The results obtained are based on steady-state turbulent flowfields computations. The baseline wing is ONERA M6. Various wing planforms are generated by linearly or parabolically varying the spanwise stacking location. The critical Mach number is determined by changing the freestream Mach number for a fixed angle of attack. On the other hand, the analysis of the drag force is carried out by changing the angle of attack to keep the lift force constant.

Findings

By changing the stacking location, the critical Mach number and the corresponding lift-to-drag ratio have increased by around 7 and 3%, respectively. A reduction of 12.8% in total drag force has been observed in one of the analyzed cases. Moreover, there exist some cases in which the values of drag reduce significantly while the lift is the same.

Practical implications

The results of this new stacking approach have implied that the drag force can be decreased without decreasing the lift. This outcome is valuable for increasing the range and endurance of an aircraft.

Originality/value

This work generalizes wing sweeping by modifying the taper stacking along the span. In literature, wing sweep is enhanced using segmented stacking of taper distribution. The present study is further enhancing this concept by introducing continuous stacking (infinite number of stacking segments) for the first time.

Abstract

Purpose

This paper aims to determine the effect of black garlic (BG) on visceral fat, oxidative stress and insulin resistance (IR) compared with metformin and vitamin E in nonalcoholic fatty liver disease (NAFLD) rats.

Design/methodology/approach

A randomized post-test only design with control group was used in this study. Rats were given high-fat fructose diet enriched with 1.25% cholesterol and 0.5% cholic acid for eight weeks to induce NALFD condition. The administration of BG dose of 450 mg/200 gBW, 900 mg/200 gBW and 1350 mg/200 gBW with a comparative control of 45 mg/200 gBW of metformin and vitamin E of 9 IU/200 gBW were given for four weeks via oral gavage to reduce visceral fat, oxidative stress and improve IR. Statistical analyses were performed to examine differences between groups with one-way analysis of variance and nonparametrics test.

Findings

Rats given with three different doses of BG for four weeks did not reduce body weight from 244 ± 4.4 to 284 ± 4.6 g, 242 ± 2.5 to 272 ± 3.1 g and 240 ± 2.4 to 270 ± 3.6 g, respectively, but significantly reduced visceral fat (p =0.001) on BG groups with 3.7 ± 1.3, 2.7 ± 0.7 and 1.8 ± 0.6 g, respectively. BG improved oxidative stress (p =0.001) with malondialdehyde level 5.1 ± 0.2, 3.0 ± 0.06 and 2.3 ± 0.06 ng/mL, respectively, but did not better than vitamin E group 1 ± 0.03 ng/mL. Significant (p =0.001) improvement on insulin resistance with homeostatic model assessment IR in BG groups were 5.3 ± 0.1, 4.4 ± 0.1 and 4 ± 0.1, respectively, but not as good as metformin group 3.7 ± 0.1.

Research limitations/implications

Based on the experiment, there are several limitations including small sample size, performed on animal models in a relatively short time, did not examine organosulfurs compound (OSC) content of BG specifically and OSC affects metabolism in NAFLD remains unclear and will require further investigation.

Practical implications

BG is a functional food made from heated fresh garlic owing to the Maillard reaction and the organosulfur compounds as antioxidants. The higher the dose of BG, the greater the improvement in visceral fat, oxidative stress and IR in model NAFLD rats.

Social implications

NAFLD is a liver disorder caused by excessive fat and energy intake, the treatment strategies among others through diet modification.

Originality/value

In model NAFLD rats, BG administration improved NALFD markers but did not better rather than the metformin and vitamin E result.

Abstract

Purpose

This paper attempts to explore possible contributing factors of females' outperformance and males' underperformance in the higher education in Pakistan from teachers' perspective. The central question of the study is what are the key factors that affect female and male students' educational performance at the university level? Using Artificial Neural Network (ANN) as a framework, we attempted to predict differentials of the perceived “female outperformance” and “male underperformance” in higher education. We carried out the study by employing quantitative research methods.

Design/methodology/approach

The data for the study come from 253 teachers from University of the Punjab-largest and oldest University in Pakistan. We used a structured questionnaire for data collection. The analysis was carried out with the help of ANN model. Statistical Package for Social Sciences (SPSS) was used to analyze the data.

Findings

The testing results of ANN indicated 85.3% of teachers' perception was correctly predicted on various dimensions of performance differentials across female and male students in higher education.

Research limitations/implications

The study banks on primary data collected from teachers of the University of University of the Punjab, Pakistan. Thus, the study's universe was limited to one university – University of Punjab. It is purely based on a quantitative approach employing ANN.

Practical implications

The findings of this study have several significant implications, i.e. it makes a significant contribution to the existing body of scholarly texts on the issue of gender reverse change in academic performance in higher education.

Originality/value

The findings of this research, derived from primary data in Pakistan context, qualify this research as an original one. We also claim that this study is one of the first studies on gender reverse change in academic performance among graduate students in a public sector university of Pakistan employing ANN.
