Abstract

Already in service or under development are over a dozen or more aircraft and missiles in the general Mach 2 to 5 bracket using air breathing propulsion systems. Other major high speed projects are also at the study stage. While the subsonic combustion ramjet can span this field and beyond, the turbine engine has to transmute through a number of basic configurations to maintain an optimum mode of propulsion as Mach number increases. At present the ramjet is confined to use in missiles and the turbine engine is primarily an aircraft power unit. The trend is apparent already, however, for the turbine engine to move closer to a ramjet cycle when used above Mach 3. The following paper summarizes the features of the major high speed aircraft and missiles in being or soon to be built.

Abstract

The aim of this chapter is to explore the economic impact of the ICT sector in the Greek economy. In the first stage of this study, the ICT sector is identified as a composite agglomerate of various manufacturing and service industrial sectors of the economy, following its international definition introduced by OECD. Under this concept, we explore the main structural indicators of its business activity and quantify its impact in the Greek economy (in terms of production value, GDP, investment, and employment), utilizing the basic principles of Input-Output analysis. We further investigate the ICT sector’s linkages with other industries as a ‘route’ for technology and innovation diffusion in the Greek production system by approximating the ICT sector as the enabling force for the digital transformation of production in the face of Industry 4.0. The empirical results of this analysis are accompanied by a review of some key qualitative characteristics of the sector and elaborate on major challenges and relevant policy implications that arise.

This study aims to examine the share of foreign direct investment (FDI) in creating the value added (VA) of innovative and other industries in Poland in 2004–2020.

Abstract

Purpose

This study aims to examine the share of foreign direct investment (FDI) in creating the value added (VA) of innovative and other industries in Poland in 2004–2020.

Design/methodology/approach

In terms of the empirical analysis of FDI stocks, their locations were divided into innovative and other industries. The differences in the creation of VA are presented by domestic and foreign enterprises. The impact of FDI stocks in individual industries on gross domestic product (GDP) changes was assessed using the vector error correction model (VECM).

Findings

FDI from innovative industries generated approx. 7% VA of the Polish economy in the years 2004–2020. In 2009–2018, the share of VA of foreign enterprises in innovative industries in Poland showed a faster growth (by 5 pp) than in other industries. The results of decomposition confirm that the level of explanation of GDP by FDI in innovative industries is higher than in other industries.

Research limitations/implications

Changes in the classification of activities reduce the time series period available.

Practical implications

This study explains the participation of foreign and domestic enterprises in creating VA. The results are useful to pursuing the national investment policy.

Social implications

The economic results of domestic and foreign enterprises in the host country affect the economic growth and development and ultimately the socio-economic conditions of life.

Originality/value

This work provides some additional explanations for the inconclusive results of international research into the impact of FDI on GDP or the spillovers effects. Its usefulness concerns the detailed impact of FDI by industrial structures on GDP.

Abstract

The balanced scorecard (BSC) allows firms to place importance on both financial and nonfinancial performance measures in four perspectives for developing and implementing corporate strategy and performance evaluation. The BSC literature however provides minimal insight on how to set targets, how to weigh measures when evaluating managers and the firm, and how to resolve conflicts that arise in the BSC process. Researchers have attempted to fill these gaps using two contending approaches. In particular, Datar et al. (2001) uses an agency model to select the optimal set of weights and more recently Herath et al. (2009) develop a mathematical programming–based collaborative decision model to find the optimal (or approximately optimal) set of target and weights considering inputs from two parties. In this article, we apply the Herath et al. (2009) model to a detailed BSC example. We demonstrate how the collaborative BSC model can be implemented in Microsoft Excel by practitioners to minimize BSC conflicts. Finally, we discuss how the model facilitates alignment and a culture of open reporting (information sharing) around the BSC that is necessary for its effective implementation.

Abstract

The aim of this chapter is to determine the relationship between labor productivity and economic development. In this context, the annual data of Turkey on a range of 1970–2017 are included in the study period. On the other hand, these data are tested with the help of Toda Yamamoto causality analysis. Thus, it will be possible to determine whether there is a strong relationship between the two variables. According to the obtained results of the analysis, it is defined that there is a causal relationship from labor productivity to economic growth in Turkey. Based on these results, it can be said that labor productivity should rise in order to increase economic development in Turkey. For this purpose, educational programs in Turkey can be revised with the help of a detailed study. In this process, cooperation with companies to understand the needs in the market plays a key role. Additionally, regulations should also be prepared related to the salaries of the employees. If it can be possible to prevent employees from receiving wages below a certain amount by placing a minimum legal limit on salaries, it will be possible to increase the motivation of the employees. This situation has a positive and significant contribution to the labor productivity.

Abstract

Purpose

Employment exchanges have been playing a significant role in the worldwide labor market for more than a hundred years now. In India, since 1946, millions of aspiring Indian youths have registered themselves with the government-run employment exchanges to find a job. About four million job seekers got registered at 1,000 employment exchanges in India, it is important to analyze the placement statistics of these exchanges. In recent years, new methods of job search have evolved. This study examines whether employment exchanges are effective in the changed scenario?

Design/methodology/approach

Using state-level employment exchange data for the period 2010–2011 to 2019–2020, this study analyzes the determinants of job placement at employment exchanges in India. A critical analysis of the functioning of employment exchanges along with recommendations to improve the job search ecosystem in India is also presented in the study.

Findings

This study found that increased share of service sector in the state economy negatively impacts placement at employment exchanges.

Research limitations/implications

The absence of focus on the service sector requires policy intervention if Indian employment exchanges are to remain relavant.

Practical implications

The government administration should rethink that ignoring service sector employment potential is unaffordable for an emerging economy and employment exchanges should be aligned accordingly.

Social implications

About 30 million people are unemployed in India. If employment exchanges are transformed, it can have far-reaching socio-economic advantages.

Originality/value

This study is the first sub-country level study on the institution of employment exchanges. This study comprehensively maps the landscape of career services in India. Empirically establishing the impact of sectoral structure of economy on efficacy of employment exchanges, and makes the case for policy intervention that is needed to keep the employment exchanges relevant in India.

Abstract

Using data from the 2013 European Company Survey, this chapter operationalizes the representation gap as the desire for greater employee involvement in decision-making expressed by the representative of the leading employee representative body at the workplace. According to this measure, there is evidence of a substantial shortfall in employee involvement in the European Union, not dissimilar to that reported for the United States. The chapter proceeds to investigate how the size of this representation gap varies by type of representative structure, information provided by management, the resource base available to the representatives, and the status of trust between the parties. Perceived deficits are found to be smaller where workplace representation is via works councils rather than union bodies. Furthermore, the desire for greater involvement is reduced where information provided the employee representative on a range of establishment issues is judged satisfactory. A higher frequency of meetings with management also appears to mitigate the expressed desire for greater involvement. Each of these results is robust to estimation over different country clusters. However, unlike the other arguments, the conclusion that shortfalls in employee involvement representation are smaller under works councils than union bodies is nullified where trust in management is lacking.

Abstract

Purpose

The purpose of this paper is to take a serious look at the relationship between joint consultation systems at the workplace and employee satisfaction, while at the same time accounting for the (possible) interactions with similar union and management-led high commitment strategies.

Design/methodology/approach

Using new, rich data on a representative sample of British workers, the authors identify workplace institutions that are positively associated with employee perceptions of work and relations with management, what in combination the authors call a measure of the “good workplace.” In particular, the authors focus on non-union employee representation at the workplace, in the form of joint consultative committees (JCCs), and the potential moderating effects of union representation and high-involvement human resource (HIHR) practices.

Findings

The authors’ findings suggest a re-evaluation of the role that JCCs play in the subjective well-being of workers even after controlling for unions and progressive HR policies. There is no evidence in the authors’ estimates of negative interaction effects (i.e. that unions or HIHR negatively influence the functioning of JCCs with respect to employee satisfaction) or substitution (i.e. that unions or HIHR are substitutes for JCCs when it comes to improving self-reported worker well-being). If anything, there is a significant and positive three-way moderating effect when JCCs are interacted with union representation and high-involvement management.

Originality/value

This is the first time – to the authors’ knowledge – that comprehensive measures of subjective employee well-being are being estimated with respect to the presence of a JCC at the workplace, while controlling for workplace institutions (e.g. union representation and human resource policies) that are themselves designed to involve and communicate with workers.

Abstract

Purpose

The Department of Information Science of the Heinrich-Heine-University in Düsseldorf is currently conducting a research project on Informational World Cities – the prototypical cities of the knowledge society, which have been growing in the twenty-first century. In total, 31 potential Informational World Cities were identified and a set of criteria was developed to evaluate the degree of informativeness of a city through coherent criteria. The purpose of this paper is to investigate London.

Design/methodology/approach

The investigation was based on the Grounded Theory, ethnographic field research, interviews, bibliometrics, patentometrics, official statistics and the analysis of web content. During the stay in London, eight semi-standardised interviews according to SERVQUAL were conducted.

Findings

The characteristics of an Informational World City are well-marked in most cases, especially London’s knowledge infrastructure. Furthermore London places value on smart innovations and tries to adapt public transport to the growing population. This includes, next to an enhancement of the train capacities, information and communication technology, since the digital infrastructure keeps gaining importance. The ethnic/cultural diversity as well as the international connectivity and the creative infrastructure are also distinguishing marks of London. Nevertheless, especially the digital and smart infrastructure require enhancement. London’s government is ambitioned, though, to make progress and pursues plans which are of benefit to the city’s informativeness.

Social implications

This paper gives insight into the characteristics of the prototypical city of the upcoming knowledge society.

Originality/value

This paper follows an interdisciplinary approach and combines information science, urban studies and sociology to analyse cities of the knowledge society. Furthermore it is the first time that London is considered an Informational World City in an empirical study.
