Abstract

Purpose

The purpose of this paper is to conduct a survey on research in fabric and cloth simulation using mass spring model. Also in this paper some of the common methods in process of fabric simulation in mass spring model are discussed and compared.

Design/methodology/approach

This paper reviews and compares presented mesh types in mass spring model, forces applied on model, super elastic effect and ways to settle the super elasticity problem, numerical integration methods for solving equations, collision detection and its response. Some of common methods in fabric simulation are compared to each other. And by using examples of fabric simulation, advantages and limitations of each technique are mentioned.

Findings

Mass spring method is a fast and flexible technique with high ability to simulate fabric behavior in real time with different environmental conditions. Mass spring model has more accuracy than geometrical models and also it is faster than other physical modeling.

Originality/value

In the edge of digital, fabric simulation technology has been considered into many fields. 3D fabric simulation is complex and its implementation requires knowledge in different fields such as textile engineering, computer engineering and mechanical engineering. Several methods have been presented for fabric simulation such as physical and geometrical models. Mass spring model, the typical physically based method, is one of the methods for fabric simulation which widely considered by researchers.

Abstract

Purpose

Investigated milk fat fraction differs in physical attributes, first of all in melting point and solid fat content and its influence on crystallization process of cocoa butter i.e. chocolate mass. It means that this fraction slows down crystallization rate, decreases melting point of mixture with cocoa butter and causes chocolate softness. It is very important for quality of chocolate especially chocolate with nuts or sunflower kernel. The aim of this paper was to investigate the influence of low‐melting (26°C) milk fat fraction on crystallization processes in chocolate mass and define the optimal concentration of this fraction with suitable precrystallization temperature time regime. Solid fat content of chocolate which designates the influence of precrystallization changes in chocolate mass with addition of milk fat fractions was investigated.

Design/methodology/approach

The precrystallization was performed in a laboratory crystallizer that is in a modified Brabender pharinograph, which measures the rheological characteristics as indirect parameter of crystallization properties of chocolate mass depending on milk fat fraction concentration and precrystallization temperature. The experiments were performed according to the factorial plan 32 (two factors on three levels) and the results are statistically treated.

Findings

The results showed that the optimal conditions for achieving the satisfactory tempering rate (optimal concentration of crystals in chocolate mass) are addition of 3 per cent low‐melting milk fat fraction and precrystallization temperature of 25°C.

Originality/value

The addition of high‐melting milk fat fraction slows down the chocolate mass crystallization more then low‐melting milk fat fraction. Investigated fraction influenced decreasing in solid fat content of chocolate regardless of precrystallization temperature.

Abstract

Purpose

The purpose of this paper is to explore the psychological processes involved in spontaneous co-operation by survivors of mass emergencies, and the possible implications this may have for emergency responders.

Design/methodology/approach

A qualitative interview study was conducted with 12 survivors and witnesses of the 7 July 2005 London bombings. Data were subjected to thematic analysis.

Findings

Spontaneous co-operation amongst survivors often emerged, and this was a function of a common identity that grew out of a sense of shared fate amongst those affected. Some social influence that encouraged co-operation also occurred, and this was dependent upon whether there was a sense of shared identity between source and target of influence.

Research limitations/implications

Evidence was only collected from a sub-set of one incident (7/7), thus limiting possible generalisability of the findings. Further research into comparable situations would provide a better understanding of the processes underlying mutual co-operation and support amongst emergency survivors.

Practical implications

Uninjured bystanders in emergencies can act as “zero-responders”, and so may become a useful resource which can be utilised by the emergency services in mass emergencies.

Originality/value

This is the first paper to explore in detail the social influence processes underlying spontaneous co-operation amongst survivors of emergencies, and will be of use to emergency responders.

Abstract

Purpose

This study proposes integrating the perceived risk and social influence literatures on online group buying (OGB) intentions with the basic TAM variables (perceived usefulness and perceived ease of use).

Design/methodology/approach

Based on an empirical survey of 304 online adopters of OGB in Taiwan, the paper uses structural equation modeling to confirm the research model.

Findings

The results reveal that perceived critical mass had the largest total effect on intention to use group buying websites. The findings also indicate that perceived usefulness and a sense of virtual community (SOVC) have significant effect on OGB intention. In addition, both perceived ease of use and website quality influence perceived usefulness. As expected, perceived risk has negative effect on OGB intention.

Research limitations/implications

This study only considered buying intention with regard to foodstuffs, and it is unclear whether these analytical results can be generalized to other items. Further research could apply this model to examine group coupons (such as discount vouchers for restaurants).

Practical implications

To sustain a successful group buying website, attention must be paid to enhancing user's SOVC, enlarging the critical mass, and lowering the perceived risk. Practitioners can apply the findings of this study to focus on the determinants of success for their online shopping websites.

Originality/value

Theoretically, while drawing upon TRA studies, this paper provides a model that is capable of lending an understanding of the determinants of OGB intention. From a managerial perspective, the findings indicate that webmasters can improve or manage website members' buying intentions by increasing the sense of virtual community and critical mass.

Abstract

Purpose

The purpose of this paper is to present a conceptual model based on technology acceptance with extended antecedent variables (entertainment and irritation) to examine the impact of use and gratification on e‐consumers' acceptance of B2C Websites.

Design/methodology/approach

Data were collected from a total of 238 EMBA and undergraduate students from three different Taiwan universities. Structural equation modeling (SEM) was used to evaluate the conceptual model in terms of overall fit, explanatory powers and causal links.

Findings

The analytical results showed that entertainment gratification, irritation surfing experience (mass medium), perceived usefulness and ease of Web use (information systems) are important predictors of e‐consumers' use intention. The integrated model was then assessed for variance in explanatory power regarding consumer attitude and intention toward B2C Websites.

Practical implications

Intention to use the Web is the predictor of actual use, purchase and information‐seeking behaviors in e‐consumers. Creating entertaining content and reducing distracting processes can enhance acceptance of B2C Websites.

Originality/value

A theoretical model incorporating U&G constructs into a technology acceptance model was used to investigate e‐consumer behavior in Taiwan. Although ease of use and usefulness are perceived as important issues in traditional IS environments, U&G provides managers with a different perspective.

Abstract

Purpose

This paper aims to explore the accommodation experience of customers in the budget hotel sector – a less explored but rapidly expanding sector in the hospitality industry. This study investigates the effects of such experience on customer behavior.

Design/methodology/approach

The study adopts a quantitative approach and draws on a comprehensive data set (N = 414) by using a quota sampling approach. The context of the study is the Chinese market, where budget hotels and the number of mass tourists (inbound and outbound) have increased tremendously.

Findings

This study identifies a behavioral pattern that differs from trends reported in prior studies. The finding shows that the relationship between customer experience and behavioral intentions is mediated by customer satisfaction, which similarly mediates the relationship between perceived value and behavioral intentions.

Research limitations/implications

The results provide significant implications for hoteliers in the budget hotel industry by calling for a differentiated marketing approach for this segment of customers. Furthermore, the study provides insights into the accommodation behavior of Chinese mass tourists. These findings can serve as reference for international budget hotel practitioners, especially those involved in hotels that target the increasing number of travelers from China.

Originality/value

The budget hotel sector is the first accommodation choice for many Chinese mass tourists. This study is the first to conduct a systematic exploration of the behavioral patterns of customers toward budget hotels in this context. Moreover, this study adopts a holistic approach by adopting an experiential view in measuring the overall experience of customers in budget hotels.

Abstract

Purpose

The purpose of this paper is to concern the use of analytics as a calculative engine enabling coordination and control for the development process in a creative digital business environment.

Design/methodology/approach

This research employs an explorative field study approach, using interview data from professionals working with free-to-play mobile game development. Drawing on the concepts of cycles of accumulation, accounting as an engine and mediating instruments, this study examines how organisational actors using the analytics in a digital business environment participate in the data generation that accumulates knowledge about and new insights into the desired outcome.

Findings

The real-time metrics provided the means for organisational actors to continually monitor, visualise and if necessary intervene in the creative “good game” development process. Timely quantification and visualisation of user actions, collected as digital traces, enhanced the cycle of information accumulation. This new knowledge resulted in a desire for improvement and perfection, which directed the actions towards the organisational objectives.

Originality/value

This study furthers our understanding of the performativity of accounting as an engine and the user behavioural data trace as its “fuel” in a digital product development. It highlights the role of analytics as a “fact-generating” device, capable of transforming the raw user behavioural data, the fuel, into powerful explanations through visualisations of ideals. The real-time metrics, understood as mediating instruments, enable the generation of new insights and accumulation of knowledge guiding the further development towards the desired outcome, the “good game”.

Abstract

Purpose

Reports from small‐scale incidents in which decontamination was conducted suggest that a successful communication strategy is vital in order to increase public compliance with, and reduce public anxiety about, decontamination. However, it has not been possible to examine public behaviour during large scale incidents involving decontamination. The aim of the research reported here was to examine the relationship between people's positive perceptions of responding agencies’ communication strategies and relevant outcome variables, such as level of compliance and level of reassurance, in several field exercises involving mass decontamination.

Design/methodology/approach

Data were collected using feedback questionnaires completed by simulated casualties, which contained items relating to casualties’ perceptions of the success of responding agencies’ communication strategies, their confidence in emergency responders, and their compliance with the decontamination process. Path analysis was used to examine the relationships between variables.

Findings

Results show a significant relationship between responding agencies’ communication strategies, level of public reassurance, and level of public compliance. The relationship between responders’ communication strategies and the outcome variables was partially mediated by public confidence in responders.

Practical implications

Emergency responders should focus on communication with members of the public as a key element of the decontamination process, as failure to do so could result in high levels of anxiety and low levels of compliance among those who are affected.

Originality/value

This research highlights the importance of effective responder communication strategies. Further, findings indicate the value of examining feedback from field exercises in order to facilitate a greater understanding of public experiences of the decontamination process.

Abstract

Describes the thermo‐mechanical consolidation coupling analysis and its discretization method for the simulations of nuclear waste storage on jointed rock mass using the finite element method. An anisotropic stress‐strain and permeable constitutive laws are employed for combining arbitrary oriented joint sets using compliance matrices. Evaluates the influence of non‐linear permeability of joint by cubic‐law assuming parallel plate flow caused by excavation and the local change of permeability around the excavated cavern in different joint angles. The results of the two‐dimensional rock mass models with combining arbitrary oriented joint sets show that the fluid flow direction followed along the direction of the joint sets, and this seemed to be clearly explained from the influence of joint orientations.

Abstract

Purpose

Effective communication has been recognised as an important issue for the management of incidents involving decontamination; evidence shows that failure to communicate effectively may result in increased public anxiety and non‐compliance. This paper aims to examine current provision for communicating with members of the public during decontamination, to facilitate the development of improved responder communication strategies.

Design/methodology/approach

To examine the current provision for communicating with members of the public, the authors reviewed open source decontamination guidance documents for responders, as well as published reports of emergency preparedness exercises involving decontamination.

Findings

The review of decontamination guidance documents showed that specific guidance for professional responders on how to communicate with the public during incidents that involve decontamination could be improved. Similarly, the review of published decontamination exercises shows that a stronger emphasis on communication with members of the public is needed, in addition to the use of exercises to evaluate the effectiveness of communication strategies.

Originality/value

The present research summarises existing evidence relating to how communication strategies employed by responders can shape public responses to decontamination. Analysed alongside current decontamination guidance for emergency responders, this evidence highlights potential gaps in planning for communicating with members of the public during decontamination. It is hoped that this will promote an increased understanding of the importance of communication during these types of incidents, which will in turn facilitate the development of more comprehensive responder communication strategies.
