Abstract

Purpose

The purpose of this paper is to examine the feasibility of adopting a market‐based land use model, Transfer of Development Rights (TDR), which is very popular in America and other countries as a positive land use control mechanism for conservation, in an evolving socialist land economy, namely China.

Design/methodology/approach

This paper utilizes a case study approach, supplemented by a cost‐benefit model, to estimate the feasibility of establishing a TDR model in Chongqing, China.

Findings

From the analysis, it is found that a market‐based land use mechanism can serve to maximize the benefits of all parties and can balance the interests between development pressures and conservation needs. However, this is based on a number of conditions, including: that a well‐developed legal framework should be set up, to clearly delineate property rights; that a good and enforceable planning system should be in place; and that a mature land market mechanism should be developed that allows open market prices to be realized in the trading of development rights.

Research limitations/implications

This case study is based on a hypothetical situation of one case. More data are needed to support the argument in the future.

Practical implications

Conservation is a major concern for the local governments in China, given the recent high speed economic growth. A model that can balance development pressure, while allowing the market to compensate fully for the infringement of property rights in the process of urban regeneration, is worthy of the authority's attention in future policy formulation.

Social implications

This paper shows that the society as a whole can strike a balance between the need for economic development and conservation of historic sites, provided some conditions can be met.

Originality/value

This paper fulfills an identified need to study the establishment of a market‐based land use model in the conservation policy of land in China.

Abstract

Purpose

This research paper aims to explore the relationship of financial performance and capital structure of Indian pharma firms of BSE 500, the impact of research and development (R&D) expenditure on financial performance and also explore the moderating role of competitive intensity between the existing relationship of capital structure and firm performance.

Design/methodology/approach

The balanced panel data of listed pharma firms of BSE 500 are used for the research study, and the present study adopts both the panel and ordinary least square (OLS) estimation techniques to draw the results.

Findings

The results exhibit that the high debt ratio is harmful for the accounting performance of the selected sample of pharma firms of BSE 500. Besides, market competition negatively moderates the relationship between capital structure and firm performance.

Research limitations/implications

The research findings provide evidence for the policymakers/regulators that the sample firms should discourage the high debt financing in the presence of competitive intensity in the product marketplace.

Originality/value

The core contribution of the current research is to examine impact of R&D expenditure on financial performance and the moderating role of market competition on the relationship of capital structure and firm performance to the best of the authors' knowledge, and no single study has previously explored this relationship in the context of BSE 500 pharma firms.

Abstract

Purpose

The purpose of this paper is to solve the problem of information privacy and security of social users. Mobile internet and social network are more and more deeply integrated into people’s daily life, especially under the interaction of the fierce development momentum of the Internet of Things and diversified personalized services, more and more private information of social users is exposed to the network environment actively or unintentionally. In addition, a large amount of social network data not only brings more benefits to network application providers, but also provides motivation for malicious attackers. Therefore, under the social network environment, the research on the privacy protection of user information has great theoretical and practical significance.

Design/methodology/approach

In this study, based on the social network analysis, combined with the attribute reduction idea of rough set theory, the generalized reduction concept based on multi-level rough set from the perspectives of positive region, information entropy and knowledge granularity of rough set theory were proposed. Furthermore, it was traversed on the basis of the hierarchical compatible granularity space of the original information system and the corresponding attribute values are coarsened. The selected test data sets were tested, and the experimental results were analyzed.

Findings

The results showed that the algorithm can guarantee the anonymity requirement of data publishing and improve the effect of classification modeling on anonymous data in social network environment.

Research limitations/implications

In the test and verification of privacy protection algorithm and privacy protection scheme, the efficiency of algorithm and scheme needs to be tested on a larger data scale. However, the data in this study are not enough. In the following research, more data will be used for testing and verification.

Practical implications

In the context of social network, the hierarchical structure of data is introduced into rough set theory as domain knowledge by referring to human granulation cognitive mechanism, and rough set modeling for complex hierarchical data is studied for hierarchical data of decision table. The theoretical research results are applied to hierarchical decision rule mining and k-anonymous privacy protection data mining research, which enriches the connotation of rough set theory and has important theoretical and practical significance for further promoting the application of this theory. In addition, combined the theory of secure multi-party computing and the theory of attribute reduction in rough set, a privacy protection feature selection algorithm for multi-source decision table is proposed, which solves the privacy protection problem of feature selection in distributed environment. It provides a set of effective rough set feature selection method for privacy protection classification mining in distributed environment, which has practical application value for promoting the development of privacy protection data mining.

Originality/value

In this study, the proposed algorithm and scheme can effectively protect the privacy of social network data, ensure the availability of social network graph structure and realize the need of both protection and sharing of user attributes and relational data.

Abstract

This paper presents the results of research into the process of testing controlled impedance circuit boards. It aims to provide a general introduction to the subject of controlled impedance circuit board production for manufacturers wishing to make this type of board in the future and offers constructive suggestions for those who may want to improve on their current process. Consequently, in addition to describing test issues there are references to some of the other main subject areas that require attention when the production of high quality controlled impedance circuit boards is to be considered, namely design, materials and fabrication. The content of this paper is based on production trials that were conducted by MEPD Met‐Etch (Selkirk) Ltd at their manufacturing facilities in Scotland as part of a UK Ministry of Defence research contract. The results of this research were included in a report for the UK Defence Research Agency (Electronics Division) and subsequently were also detailed in an individual ‘Guidelines for Designers’ document. This document has since been separately submitted to ECL 19 with a view towards incorporation into the CECC 23000 Approval System. In order to verify the test results, separate comparison measurements were also conducted by other circuit board manufacturers using a range of suitable test instrumentation. There is a growing requirement in the printed circuit board industry for a simple means of testing controlled impedance boards. This paper promotes the use of computer‐controlled test instrumentation so that accurate and repeatable measurements can be made by production staff in a manufacturing environment. If this is achieved, it should be possible to close the quality loop on controlled impedance circuit board production using normal statistical process control techniques.

Abstract

Purpose

The paper aims to examine some of the requirements for an industrial strength loss measurement technique in FR4 laminate printed circuit boards and, in particular, to take a closer look at one new candidate method.

Design/methodology/approach

The paper highlights some of the issues in transferring an essentially laboratory‐based measurement technique to high volume manufacturing, i.e. the shop floor. The paper uses the newly proposed SET2DIL method of characterizing loss, comparing results with established laboratory methods and discusses the practical issues, such as the design of new test probes and coupons, in its implementation.

Findings

The paper shows that current time‐consuming laboratory methods of loss measurement using vector network analysers (VNAs), with their associated high skill requirements, though accurate and reproducible, are not viable for the factory floor, with its challenging environment and, occasionally, lack of specialized expertise. The SET2DIL method of loss measurement appears to offer a robust and reliable method of measuring and predicting loss in FR4 and should achieve wide approval across the board manufacturing industry.

Originality/value

The results of extensive testing are compared favourably with the results of established reference methods using VNAs, showing good correlation, and the SET2DIL method is recommended as being suitable for use in a high volume production environment.

Abstract

Purpose

The purpose of this paper is to examine the regulatory, policy and market‐based approaches taken to incorporate biodiversity conservation in the management of urban growth in Sydney and more broadly in New South Wales, Australia's most populous state. Problems associated with managing Sydney's growth – particularly from the intersection of dealing with perceived property rights and the protection of natural resources such as biodiversity – are identified, and the scope for hybrid “smart regulation” is examined.

Design/methodology/approach

The relevant issues are illustrated through significant State Government development decisions relating to the retention of biodiversity in the new growth areas of Sydney.

Findings

The paper argues that to better integrate biodiversity conservation in Australian cities a mixed approach be adopted in which a number of tools are utilised – and that this needs to occur in the context of a sound overarching strategic planning framework. This constitutes a hybrid approach involving a “fixed” strategic spatial plan informing statutory‐based regulation primarily through zoning and other development controls, augmented by a range of market based tools implemented through statute and common law measures such as conservation covenants.

Originality/value

Singular reliance on traditional “command and control” regulatory approaches as both a cause and ineffectual solution to the problems faced in biodiversity conservation is highlighted. Newer “market based” mechanisms which are being introduced (e.g. biobanking), or should be adopted (e.g. transferable development rights), and management at the strategic level (e.g. biodiversity certification), are examined.

Abstract

Purpose

This paper aims to analyze the negative impact of surface mount (SMT) pad and imperfect via structure such as stub, pad, non-functional pad (NFP) and anti-pad on the signal integrity at 40 Gbps transmission on printed circuit board (PCB) due to impedance mismatch or discontinuity. The optimized modeling of via and SMT structures is performed to achieve minimal impedance mismatch and insertion loss less than 10 dB for six-inch full path transmission line between transmitter and receiver on PCB at Nyquist frequency 20 GHz.

Design/methodology/approach

This work is split into two phases. The first phase involves optimization of via and SMT structures in three-dimensional electromagnetic (3DEM) simulation using Hyperlynx Via Wizard and Keysight EMPro software, respectively, followed by analysis of time domain reflectometry (TDR) and insertion loss (Sdd21). Whereas, in the second phase, full path hybrid mode simulation involving vias for signal layer transition, a 6-inch PCB channel and SMT pads is performed using Keysight ADS software to observe the TDR, Sdd21 and eye diagram at 40 Gbps transmission.

Findings

Imperfect via and SMT structures have a negative effect on signal reflection and attenuation. The optimized via and SMT minimizes the impedance mismatch by 81 per cent and insertion loss by 4.5 dB, ultimately enlarging the eye diagram opening to achieve minimal data loss at receiver with 40 Gbps transmission.

Originality/value

The results of original empirical research work on signal integrity analysis that optimizes the PCB channel design to achieve 40 Gbps signal transmission are presented in this study. It serves as a reference guide for high-speed PCB layout design.

Abstract

Purpose

The aim of this study is to empirically examine firm-specific factors that influence the financing decisions of companies listed on BSE-500 index. Firm-specific variables such as profitability, company size, growth potential, liquidity, non-debt tax shields, age and tangibility were evaluated in this study.

Design/methodology/approach

This empirical research is performed using longitudinal data of 366 companies listed on the BSE 500 index during 2006–2020. Pooled ordinary least square method is employed to classify primary determinants of capital structure.

Findings

The results show that profitability, liquidity and non-debt tax shield are negatively associated whereas, company size, growth potential, age and tangibility are positively associated with the capital structure. The authors’ observations are aligned with either the trade-off hypothesis or the principle of the pecking order.

Research limitations/implications

This study helps to better understand how firm-specific factors play a vital part in deciding the capital structure of businesses and makes a significant contribution to the literature. Thus, the present study examines the drivers of the capital structure among sample Indian companies, which allow firm managers and regulators to recognise relevant variables that optimise performance. This study is limited to Indian companies and only firm-specific variables were considered.

Originality/value

The current research focuses on the impact of firm-specific variables upon the financing decisions of Indian companies. In the background of developed countries, numerous studies in this field have been carried out. In the Indian context, however, there are not many researches in this area. However, the existing studies use one or two ordinary least square (OLS) models, resulting in a lack of thorough research and robust results. To address this gap in the analysis, the current study used four models and used a 15-year time frame, as well as a bigger sample size, which was not used in earlier investigations.

Abstract

Purpose

This paper aims to clarify the functions of tourism interpretations of consumer products in a tourist-generating region (TGR) as a means of marketing the tourist destination region (TDR) through tea tourism.

Design/methodology/approach

This is a case study of the Thai Shizuoka Green Tea brand working to promote tea tourism in Shizuoka, Japan. It is used to identify the functions of tourism interpretations of consumer products in a TGR related to the concept of brand identity. This paper assessed Thai consumers’ opinions on the efficiency of tourism interpretation through a sample of 404 questionnaires and with interviews of ten young females, the primary respondents.

Findings

Tourism interpretations of the TGR’s consumer products are important for promoting the TDR through five premises: 1) motivating visitors to visit the destination, 2) communicating the place’s meaning, 3) targeting potential tourists, 4) differentiating the destination from other sites and 5) activating value co-creation. Premises 1 and 2 were assumed to stem from visitors’ enjoyment of the tea; the packaging motivated their visit to Shizuoka, its origin. Premise 3 concerns young women who view the product as a premium healthy drink. Premises 4 and 5 are based on the brand’s essence, implying the tea company’s partnership between Thailand and Japan.

Originality/value

Tourism interpretation plays a significant role in TDRs’ success; however, it can be implemented with other consumer products and an efficient brand identity, to create an image of a destination.

Abstract

Purpose

This paper aims to shed light on the risk structure in the presence of Islamic banking. The author concentrates on the relationship between Islamic banking and conventional banking in Turkey. Islamic banking and conventional banking are considered to be different kinds of sources for funding. Returns in the conventional banking are expected to be heavily influenced by the interest rate in the money market. However, Islamic banking returns are interest-free so that interest rate changes are not expected to affect the deposit returns in Islamic banks. Interest rates in the economy are a proxy to highlight the general risk level of the economy. By looking at the causal relationship between the deposit returns of both Islamic banks and conventional banks, it is possible to address the different types of banking in the general risk structure of the economy. This is one of the first studies to address the mentioned difference in banking sector in Turkish economy.

Design/methodology/approach

This paper tries to identify the direction of causality between Islamic and conventional banking term deposit rates by means of Granger Causality. Also, Granger Causality test results will guide to explore the Islamic and conventional banking deposit return linkages. The author has extended the study with vector autoregressive analysis to understand the correlation structure between conventional deposit rates and the profit–loss sharing ratio of Islamic Banks. The author has also extended this study with impulse response functions to see whether the shocks hitting into the conventional banking affect Islamic banking and vice versa.

Findings

The results suggest that there is no significant clear relationship between both banking sectors. This result can be interpreted, as Islamic banks do not adjust their profit–loss sharing (PLS) ratios pegged to the interest rate offered by conventional banks. Also, conventional banks determine their interest rate without any connection to the Islamic banking PLS ratios. Overall results of this study contradict the findings of studies which conclude that Islamic banking might not be different from the conventional banking. It is reported that inferences from pair-wise Granger causality alone might be spurious, as the analysis based on non-stationary series can be a consequence of time functional characteristics of the time series.

Social implications

The results can be taken as counter evidence to the hypothesis “Islamic banks determine their PLS ratios based on the interest rates offered by conventional banks”. This address that the Islamic banks may offer alternative financing methodology which has different procedure. Hence, Islamic finance can be taken as an alternative method with its asset-based healthier structure.

Originality/value

This is one of the first studies to address the Islamic versus interest-based banking difference in banking sector in Turkish economy. This paper tries to identify the direction of causality between Islamic and conventional banking term deposit rates by means of Granger causality.
