This paper introduces computer vision systems (CVSs), which provides a new method to measure gem colour, and compares CVS and colourimeter (CM) measurements of jadeite-jade colour in the CIELAB space. The feasibility of using CVS for jadeite-jade colour measurement was verified by an expert group test and a reasonable regression model in an experiment involving 111 samples covering almost all jadeite-jade colours. In the expert group test, more than 93.33% of CVS images are considered to have high similarities with real objects. Comparing L*, a*, b*, C*, h, and ∆E* (greater than 10) from CVS and CM tests indicate that significant visual differences exist between the measured colours. For a*, b*, and h, the R2 of the regression model for CVS and CM was 90.2% or more. CVS readings can be used to predict the colour value measured by CM, which means that CVS technology can become a practical tool to detect the colour of jadeite-jade.

Navigational service is one of the most essential dependency towards any transport system and at present, there are various revolutionary approaches that has contributed towards its improvement. This paper has reviewed the global positioning system (GPS) and computer vision based navigational system and found that there is a large gap between the actual demand of navigation and what currently exists. Therefore, the proposed study discusses about a novel framework of an autonomous navigation system that uses GPS as well as computer vision considering the case study of futuristic road traffic system. An analytical model is built up where the geo-referenced data from GPS is integrated with the signals captured from the visual sensors are considered to implement this concept. The simulated outcome of the study shows that proposed study offers enhanced accuracy as well as faster processing in contrast to existing approaches.

In current literature and practices, there are no systematic and user-oriented intermodal transportation performance measures. After identifying customer needs and transportation goals, this paper proposes a set of system-level performance measures for intermodal transportation that are user-oriented, scalable, systematic, and scientific. The measures can be used to compare intermodal design alternatives or to evaluate existing transportation systems with any size and any mode. The highway system in Mississippi is analyzed as a case study. The case study demonstrates the existing data sources, the methods of calculating the measures, and the means of evaluating transportation systems with the measures.

Privatisation is one of the key elements of the package of neoliberal reforms in the transition economies of Central and Eastern Europe which collectively constitute the ‘sharp shock’ strategy. In this, privatisation is ascribed the role of redistributing and clarifying property rights, which is an assumed precondition for efficiency improvements in individual firms. In practice, the transformation is characterised by path dependency, cultural and political legacies, and uneven and partial reform of market institutions and of regulation. We contribute to the debate on the link between property rights and firm-level performance in three main ways. First, we analyse the tourism sector as a counterbalance to the emphasis in the existing literature on manufacturing and financial services; particular emphasis is given to the roles of ‘operators’ and the ‘nomenklatura’, and to complex, nonlinear shifts in property rights. Second, we assess the performance of tourism firms created by different forms of creative and distributive privatisation; this emphasises the diversity of property rights, market segmentation, and the capital and debt structures of firms. Third, the value of the concept of ‘recombinant’ property for analysing the complex and changing forms of property rights is critiqued. These arguments are illustrated through a case study of tourism in the Czech Republic and Slovakia.

Purpose This study aims to comprehensively examine the integration of organisational- and individual-level performance management systems (PMSs) in the context of public sector organisations (PSOs) of developing countries (DCs), by investigating the elements of PMSs in the studied organisation. Design/methodology/approach A case study in a large PSO of a developing country was conducted. The design of the study and the data analysis drew on Ferreira and Otley’s PMSs framework. Data were captured from electronic and printed document archives, online written interviews with participants and face-to-face interviews. The data then were triangulated and analysed thematically. Findings The study reveals a recursive relationship between culture and PMSs, and identifies conflicting regulatory requirements and a lack of information technology capacity led to the development of dual, loosely coupled PMSs in the studied organisation. Research limitations/implications The findings may not be generalisable beyond a large, PSO in a developing country; the study did not consider the linkages between the integration of organisational- and individual-level PMSs and other PMSs; the study looked at only two notions of culture; and the study asked participants to recall past events, so was retrospective in its design. Practical implications The findings illustrate the need for public sector managers and key policymakers to use both formal and informal control systems, together with technical and social integration mechanisms, as well as management accounting (MA) and human resources management (HRM) control approaches, when attempting to integrate organisational- and individual-level PMSs in the PSOs of DCs. Social implications Future studies may usefully investigate the integration of organisational- and individual-level PMSs in different contexts, consider culture and contextual factors when investigating the integration of organisational- and individual-level PMSs in different contexts, examine whether national culture also substantially impacts PMSs in other countries and attempt to inform the MA literature by drawing on HRM theory and research on individual-level PMSs. Such studies may help to address the gap between PMS theory and practice and better allow MA researchers to contribute to practice. Originality/value The study contributes to management control systems (MCSs) and PMSs literature by extending our understandings in the relationship between accounting and non-accounting controls, the contextual factors that affect PMSs and highlighting the importance of considering cultural context when integrating PMSs in the PSOs of DCs.
