Abstract
Purpose
This paper aims to develop flame-retardant (FR) polyamide 12 (PA12) nanocomposite from regenerated powder via selective laser sintering (SLS), an additive manufacturing technique.
Design/methodology/approach
First, the morphology, processibility, thermal and mechanical properties of PA12 regenerated powder, consisting of 50 wt% new and 50 wt% recycled powder, as well as corresponding printed specimens, were evaluated to characterize the effects of previous SLS processing. Second, flame-retardant PA12 was developed by incorporating both single and binary halogen-free flame retardants into the regenerated powder.
Findings
It was found that the printed specimens from regenerated powder had much higher tensile and impact properties compared to specimens made from new powder, which is attributed to better particulate fusion and coalescence realized in higher temperature SLS printing. The effect of FRs on thermal, mechanical and flame retardant properties of the PA12 composites/nanocomposites was investigated systematically. It was found that the nanoclay, as a synergist, improved both flame-retardant and mechanical properties of PA12. UL94 standard rating of V-0 was achieved for the printed nanocomposite by incorporating 1 wt% nanoclay into 15 wt% phosphinates FR. Moreover, on average, the tensile and impact strength of the nanocomposite were increased by 26.13% and 17.09%, respectively, in XY, YZ and Z printing orientations as compared to the equivalent flame retardant composite with 20 wt% of the phosphinates FR.
Originality/value
This paper fulfills the need to develop flame retardant parts via SLS technology with waste feedstock. It also addresses the challenge of developing flame retardant materials without obviously compromising the mechanical properties by making use of the synergistic effect of nanoclay and organic phosphinates.

Abstract
Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract
Discusses the transfer of undertakings in the UK, referring to the Transfer of Undertakings (Protection of Employment) Regulations of 1981, the Employment Rights Act 1996, and the Acquired Rights Directive 1977. Provides the raison d’etre of the Acquired Rights Directive and outlines how it was implemented in the UK. Talks about the confusing jurisprudence of the European and British courts, mentioning the European Court of Justice’s challenges to the directive, the 1994 proposals, amended 1997 proposals, the Commission’s memorandum of 1997 and the UK government’s consultation papers. Describes how the European Directive is applied and interpreted in relation to the Acquired Rights Directive and transfer of undertakings. Outlines the regulations controlling compulsory competitive tendering. Points out the obligation to inform and consult on the transfer of an undertaking and how the directive is enforced if this fails to occur. Notes the effect a relevant transfer has on existing collective agreements and the legal implications of dismissing employees by reason of the relevant transfer. Looks at the European Commission’s proposal for a directive on safeguarding employees’ rights in the event of transfer and the implications that would have on UK business. Concludes that a new directive is needed, building on the 1977 Directive but ironing out its inconsistencies.

Abstract
Purpose
Because of its omission of social influences, conventional animosity research has failed to sufficiently consider consumption context. To address this limitation, this research constitutes two interrelated parts: (a) investigating how normative influences (value-expressive and utilitarian influences) shape consumers’ animosity attitudes and purchase intentions; and (b) building on the normative influence perspective and separating consumption context into purchase (online vs. offline) and usage (private vs. public) contexts. The goal was to examine under the condition of preference conflict, how consumption contexts with different degrees of behavioral exposure affect purchase decisions.
Design/methodology/approach
One pretest, one survey and one experiment were conducted to empirically validate the proposed research model.
Findings
In an international crisis, consumers’ attitudes and behaviors were socially determined. Moreover, the online purchase with private usage (offline purchase with public usage) condition resulted in the highest (lowest) level of purchase intention.
Originality/value
This research pioneers in the animosity literature to identify the possibility of preference conflict in a situational international crisis, and to more delicately separate the conventional consumption context into purchase and usage contexts.

Abstract
Corruption has been defined in different ways by various scholars and organizations according to cultural, legal, or other factors (Organization for Economic Co-operation and Development, 2008, p. 22). The word “corruption” is derived from the Latin word corruptus and, according to the dictionary, it has six possible meanings: dishonesty for personal gain; depravity; undesirable change; corrupting of something; altered word or phrase; or rotting.1 However, the most useful typology of contemporary social science definitions of corruption is Arnold J. Heidenheimer's typology of three major types of definitions (Heidenheimer, 1970, pp. 4–6).

Abstract
Purpose
The present research responds to researchers’ calls for more research of consumer animosity on potential boundary conditions (e.g. product categories) and marketing strategies that may mitigate such negative impacts on marketers’ product and/or brand performance, with a special focus on the soft service sector. This paper aims to address the unique characteristics of service internationalization, i.e. cultural embeddedness, hybridized country origins and high consumption visibility, by proposing a social identity signaling model to explain consumer animosity effects in the soft service sector.
Design/methodology/approach
Two surveys (Pretest with 240 participants and Study 1 with 351 participants) and one experiment (Study 2 with 731 participants) were conducted to empirically test our hypotheses in the Japanese-Chinese relationship context.
Findings
The stronger the national/cultural symbolism and social expressiveness, the stronger the consumer avoidance for the service category. Then the consumer culture positioning strategy that can mitigate an offending country’s cultural symbolism can reduce consumer avoidance.
Originality/value
This research introduces two factors that could affect the negative social identity signaling capacity of service categories in the animosity context: the national/cultural symbolism reflecting an offending country and the social expressiveness communicating social identity. In line with the social identity signaling perspective, the present research specifically uses consumer avoidance as the dependent variable to capture the notion that consumers avoid consuming services because they wish to avoid being associated with an offending country that may threaten their in-group social identities.
