Abstract

The advent of derivatives and structured products has coincided with a proliferation of fixed income models used to analyze hedging, pricing, forecasting, and estimation for the term structure of interest rates. This article evaluates five models HoLee (HL); Black‐Derman‐Toy (BDT); Vasicek; Cox‐Ingersoll‐Ross (CIR); and Heath‐Jarrow‐Morton (HJM) (see Exhibit 1) that are currently used by structured finance practitioners. We suggest which models are most appropriate for assets with different time horizons, interest rate sensitivities and cashflow properties. The authors link model selection to structured financial instruments with the singular focus on the trade‐off between model precision/complexity and calculation costs.

Abstract

The main streams of the supply chain are defined as material, information and financial flow. There have been many studies and practical cases regarding the flow of material and information including information sharing. However, financial flow related studies have not been widely examined relatively, compared with their importance.

The information sharing is recognized as the method that can reduce the Bullwhip effect in supply chain management. The author intends to analyze the impact of financial information sharing on the results of the supply chain.

In the point of supply chain risk management view, the author examined the impact of financial flow among the various factors that can impede the stability of the supply chain.

In this study, the author embodied the simulation regarding the impact of financial information flow on supply chain performance and stability based on the system dynamics methodology and analyzed the performance.

Assuming the supply chain, composed of supplying company, manufacturing company and sales company , the author embodied the simulation model and assumed that working capital and cash information sharing were achieved. The author embodied the model to affect the settlement conditions according to the results of financial information sharing.

Abstract

Purpose

In mobile platforms, an increasing number of third-party developers (developers) create new ideas and enhance their expertise through knowledge sharing on the developers’ community. Notwithstanding the importance of the sharing and its uniqueness on the mobile platform contexts, the motivational factors of sharing their knowledge on the community have been underinvestigated. Therefore, this paper aims to provide a comprehensive framework to enhance the knowledge sharing in the mobile platform context.

Design/methodology/approach

Based on the theory of reasoned action, this paper incorporated intrinsic and internalized extrinsic motivations with two unique features of platform environments: platform open policies and coopetitive relationships. To test, an online survey was distributed to four developer communities in Korea, two Android and two iOS communities.

Findings

The results show that a platform pursuing higher openness causes the developers to find higher social pressure for information sharing. The coopetitive relationship with other developers in the same platform takes dissimilar roles; reciprocity significantly increases subjective norm, while rivalry does attitude. Self-efficacy and self-development stimulate knowledge sharing. Furthermore, multilevel analysis to capture the difference between two leading mobile platforms indicates no path difference but, interestingly, shows significant mean difference between the two platforms regarding perceived openness and rivalry.

Originality/value

With this paper, the authors fulfill the need to understand the knowledge-sharing intention of developers in the context of mobile platforms where developers can be potential competitors or cooperators and where two platforms offer different policies and developmental environments.

Abstract

Purpose

The purpose of this paper is to identify risk patterns of road and bridge projects in Vietnam, where the construction market is emerging but attractive to construction organizations, especially foreign companies.

Design/methodology/approach

Using a questionnaire, experienced practitioners of various contractors were interviewed to collect risk-related data in terms of actual likelihood and impact from road and bridge construction projects in Vietnam. Using the collected data of actual likelihood and impact, the specific probability and impact of risk factors were determined for different types of road and bridge projects, including small and medium type, big type, government-funding type, and other-funding type (e.g. official development assistance funds, public-private partnership).

Findings

The results of analysis indicate the specific probability and impact of risk factors in four risk themes, including contractor-related, project-related, owner-related, and external risks. Actual risk patterns for different types of road and bridge projects in Vietnam were identified.

Practical implications

The identification of actual risk patterns could help practitioners to know which risk factors are severe in frequency and/or impact. Hence, they could establish proper strategies to manage risk-related problems of road and bridge projects, in which they are directly involved.

Originality/value

The findings of this study could provide construction companies, especially foreign companies, with a better understanding of real risk panorama in Vietnamese road and bridge construction. Hence, they could make effective improvements on risk management of road and bridge projects in Vietnam.

Abstract

Purpose

The purpose of this paper is to examine the effects of sentence combining (SC) and sentence decombining (SD) activities on fostering reading comprehension. As a widely used writing activity for enhancing syntactic fluency in English Language Arts (ELA) classes, SC requires learners to combine short sentences into longer and more complex sentences, while SD requires learners to break down a long sentence into the shortest grammatically allowable sentences.

Design/methodology/approach

This study assessed the effects of SD and SC in comparison with a control group on the improvement of reading comprehension ability among college students learning English as their second language (L2) in the context of a six-week English language learning program. Participants with overall intermediate English language proficiency were randomly assigned to one of three different conditions: SC, SD and control. Also, a subset of the participants was interviewed after the intervention.

Findings

The results showed that SD was more effective than SC or control condition in enhancing syntactic knowledge and reading comprehension, as measured by a standardized English proficiency test. Data obtained from post-study interviews further suggested that only SD was perceived by the participants as having enhanced their reading comprehension.

Originality/value

The present study provides a valuable addition to a body of research on sentence manipulation activities in ELA classes. For those L2 learners who have passed a pre-intermediate threshold level, SD appears to be more beneficial than SC in enhancing syntactic knowledge, which, in turn, appears to contribute to better reading comprehension.

Abstract

Purpose

The purpose of this paper is to show how to properly use the method of replacement to construct mixed two- and four-level minimum setup split-plot type designs to accommodate the presence of hard-to-assemble parts.

Design/methodology/approach

Split-plot type designs are economical approaches in industrial experimentation. These types of designs are particularly useful for situations involving interchangeable parts with different degrees of assembly difficulties. Methodologies for designing and analyzing such experiments have advanced lately, especially for two-level designs. Practical needs may require the inclusion of factors with more than two levels. Here, the authors consider an experiment to improve the performance of a Baja car including two- and four-level factors.

Findings

The authors find that the direct use of the existing minimum setup maximum aberration (MSMA) catalogs for two-level split-plot type designs may lead to inappropriate designs (e.g. low resolution). The existing method of replacement for searching exclusive sets of the form (α, β, αβ) available in the literature is suitable for completely randomized designs, but it may not provide efficient plans for designs with restricted randomization.

Originality/value

The authors provide a general framework for the practitioners and have extended the algorithm to find out the number of generators and the number of base factor at each stratum, which guide the selection of mixed two-level and four-level MSMA split-plot type designs.

Abstract

Purpose

The social venture (SV) is an increasingly popular form of organization to pursue social goals using a commercial approach. Although marketing plays an important role in SV research and a key driver of the performance of SVs, how and the extent to which market conditions play a role remains understudied. This study examines if market turbulence can moderate marketing capabilities and performance relationships.

Design/methodology/approach

The authors developed several hypotheses rooted in the marketing literature and tested them using data collected from a sample of 109 SVs from East Asia (i.e. Hong Kong and Taiwan). Using multiple regression analysis and structural equation modeling, the authors analyzed the marketing capabilities and financial and social performance relationships and the positive moderating role of market turbulence.

Findings

The results suggested that market turbulence is a positive moderator which influences the effect of the marketing capabilities–financial performance relationship, but not the marketing capabilities and social performance relationship.

Originality/value

This paper attempts to interrogate the SV's marketing capabilities–performance relationship in the East Asian context and how market turbulence may enhance or weaken the relationship. This is one of the earliest papers in this research area. The key findings from this research offer valuable theoretical contribution to the study of SV performance.

Abstract

There have been several document ranking methods to calculate the conceptual distance or closeness between a Boolean query and a document. Though they provide good retrieval effectiveness in many cases, they do not support effective weighting schemes for queries and documents and also have several problems resulting from inappropriate evaluation of Boolean operators. We propose a new method called Knowledge‐Based Extended Boolean Model (kb‐ebm) in which Salton's extended Boolean model is incorporated. kb‐ebm evaluates weighted queries and documents effectively, and avoids the problems of the previous methods. kb‐ebm provides high quality document rankings by using term dependence information from is‐a hierarchies The performance experiments show that the proposed method closely simulates human behaviour.

Abstract

Purpose

This study analyzed the explicitness, the salience of ethics and the transparency of messages in firms' social reports based on their significance to strategic corporate social responsibility (CSR) communication.

Design/methodology/approach

Drawing on institutional theory, this content analysis investigated 750 social reports from 125 firms for a ten-year period in liberal market economies (LMEs: US, UK), coordinated market economies (CMEs: Germany, Japan) and state-led market economies (SLMEs: France, South Korea).

Findings

First, firms in CMEs showed the highest level of transparency, and in all market economies, an overall trend of increase in the level of transparency was found. Second, firms in SLMEs communicated their CSR activities least explicitly. Third, firms in CMEs showed the lowest salience of ethics.

Originality/value

Useful theoretical as well as practical implications are provided in relation to the institutional perspective to CSR, and cross-national CSR communication.
