The young generations’ conceptualisation of cultural tourism: colonial heritage attractions in South Korea

This study investigates how the younger generation conceptualise cultural tourism attractions associated with modern history in contemporary South Korea. Particular attention in this study is given to heritage attractions built in the Japanese colonising past. By analysing data obtained through a Multiple Sorting Procedure, this study identifies the underlying facets of heritage attractions the younger generation consider to be important when appreciating the heritage attractions. This study examines the socio-psychological properties and meanings that the heritage attractions communicate with respect to young Koreans’ sense of national identity. This study found that a range of constructs emerged in understanding heritage attractions. Social and political meanings embedded in the heritage attractions become a key determinant in appreciating heritage attractions with respect to a sense of national identity. These findings from South Korea suggest invaluable messages that can inform our understanding of, and planning regenerating negative-natured heritage attractions for tourism in contemporary society.     

Measuring Retailers' Sustainable Development

This study aimed to develop a framework and measurement items for retailers to assess sustainability while avoiding potential subjectivity by combining top‐down and bottom‐up approaches, and verifying their validity based on consumer perceptions of sustainable retailing. The framework consisted of 54 measurement items categorized into a three‐order hierarchical model. At the top level of the model, there were three third‐order dimensions respectively related to consumers, retailers, and society. At the middle level, eight second‐order sub‐dimensions associated with retailing mix were classified into the aforementioned third‐order dimensions. At the bottom level, there were 21 first‐order sub‐dimensions related to the sustainable retailing activities. The development of sustainability assessment by combining top‐down and bottom‐up approaches and including consumer perceptions will allow retailers to assess their sustainability more strategically, as it will reduce the subjectivity and increase consumers' recognition of sustainable retailing.

Estimating the space requirement for outbound container inventories in port container terminals

This paper proposes a method for allocating storage space to groups of outbound containers in port container terminals. For this allocation, a collection of adjacent stacks is reserved for each group of containers with the same attributes. The impacts of various space-reservation strategies on the productivity of the loading operation for outbound containers are discussed. A method is suggested for determining the size of the space requirement for outbound container yards.     

Stochastic Modeling of Federal Housing Administration Home Equity Conversion Mortgages with Low-Cost Refinancing

Federal Housing Administration-insured reverse mortgages, known as Home Equity Conversion Mortgages (HECMs), did not originally have a provision for low-cost refinancing. If a borrower's house value increased faster than expected, the borrower could not tap that additional equity without terminating the first loan and originating a new HECM loan with full closing costs. We test several low-cost refinancing options using a stochastic simulation model that allows interest rates and house prices to vary in historically accurate patterns. Low-cost refinancing decreases the net value of the fund by 54% to $98.5 million, but it remains positive in 80% of the trials.     

Large Sample Behavior of the CTE and VaR Estimators under Importance Sampling

Abstract

The α-level value at risk (Var) and the α-level conditional tail expectation (CTE) of a continuous random variable X are defined as its α-level quantile (denoted by q_α ) and its conditional expectation given the event {X > q_α }, respectively. Var is a popular risk measure in the banking sector, for both external and internal reporting purposes, while the CTE has recently become the risk measure of choice for insurance regulation in North America. Estimation of the CTE for company assets and liabilities is becoming an important actuarial exercise, and the size and complexity of these liabilities make inference procedures with good small sample performance very desirable. A common situation is one in which the CTE of the portfolio loss is estimated using simulated values, and in such situations use of variance reduction techniques such as importance sampling have proved to be fruitful. Construction of confidence intervals for the CTE relies on the availability of the asymptotic distribution of the normalized CTE estimator, and although such a result has been available to actuaries, it has so far been supported only by heuristics. The main goal of this paper is to provide an honest theorem establishing the convergence of the normalized CTE estimator under importance sampling to a normal distribution. In the process, we also provide a similar result for the Var estimator under importance sampling, which improves upon an earlier result. Also, through examples we motivate the practical need for such theoretical results and include simulation studies to lend insight into the sample sizes at which these asymptotic results become meaningful.     

A Re-Examination of the Joint Mortality Functions

Abstract

Mortality analysis involving multiple lives is easily one of the more complicated aspects in the theory of life contingencies. In this paper, we re-investigate joint mortality functions and in particular, we examine an assertion that relates the joint-life and last-survivor random variables. This common assertion states that the sum of the lifetimes of the joint-life and the last-survivor statuses is equal to the sum of the lifetimes of the single statuses. However, we show that this assertion is not precisely correct. We therefore offer a modification to the statuses definitions so that this common assertion holds.     

Using patent information for designing new product and technology: keyword based technology roadmapping

With the rapid change in markets and technologies, it is becoming essential for firms to develop new products constantly. This can most successfully be achieved by using technology roadmaps (TRMs), which are effective tools for connecting product and technology planning. However, TRMs generally tend to overstate the qualitative and expert-dependent knowledge rather than incorporating quantitative and objective information. This paper proposes a new approach where patent data are used in a quantitative methodology to support reliable decision-making in roadmapping processes. In this study, text-mining techniques were utilized to extract the relevant information on which portfolio, co-word, and network analyses were carried out. The results were three types of product-technology maps that can be applied to specific roadmapping steps. The suggested approach is expected to yield useful information about roadmapping, and help improve the overall effectiveness and quality of the technique.     

A resource‐based perspective on human capital losses,HRM investments,and organizational performance

Reversing the focus on human capital accumulations in the resource‐based literature, the authors examine the issue of human capital losses and organizational performance. They theorize that human capital losses markedly diminish the inimitability of human capital stores initially, but that the negative effects are attenuated as human capital losses increase. They argue further that these effects are more dramatic when human resource management (HRM) investments are substantial. As predicted, Study 1 shows that the human capital losses (voluntary turnover rates)‐workforce performance relationship takes the form of an attenuated negative relationship when HRM investments are high. Study 2 shows stronger curvilinear effects of voluntary turnover rates on financial performance via workforce productivity under these conditions. Implications for resource‐based theory and strategic HRM are addressed.
