Numerous causes of taint in foods have been investigated at the Food Research Institute, Norwich over the years. This report is based on an inaugural lecture given by D.G. Land to the Taints and Off‐flavours Working Group of the British Food Manufacturing Industries Research Association.

The purpose of this paper is to propose an approach to detect Indirect Memory‐Corruption Exploit (IMCE) at runtime on binary code, which is often caused by integer conversion error. Real‐world attacks were evaluated for experimentation.

Current dynamic analysis detects attacks by enforcing low level policy which can only detect control‐flow hijacking attack. The proposed approach detects IMCE with high level policy enforcement using dynamic taint analysis. Unlike low‐level policy enforced on instruction level, the authors' policy is imposed on memory operation routine. The authors implemented a fine‐grained taint analysis system with accurate taint propagation for detection.

Conversion errors are common and most of them are legitimate. Taint analysis with high‐level policy can accurately block IMCE but have false positives. Proper design of data structures to maintain taint tag can greatly improve overhead.

This paper proposes an approach to block IMCE with high‐level policy enforcement using taint analysis. It has very low false negatives, though still causes certain false positives. The authors made several implementation contributions to strengthen accuracy and performance.

The purpose of this paper is to explore how two kinds of UK-based media positioned investment banking as dirty work during the financial crisis, thereby engaging in moral enterprise (Becker, 1963) and contributing to the shaping of society's normative contours (Cohen, 1972).

The authors employ rhetorical analysis to explore how newspaper editorials and an online blog portray investment banking as tainted between April 2008 and October 2009.

These media sources construct the values and behaviours of investment bankers, rather than the tasks of their occupation, as morally tainted. Through specific rhetorical strategies the authors advance three key arguments: bankers are morally tainted because their wealth is excessive; because their wealth is not earned; and because they are selfish and materialist.

In investigating media designations of investment banking as dirty work, the paper addresses two aspects of dirty work which are underexplored. First, it examines a high-prestige occupation and second, investigates the construction and attribution of taint to a previously untainted occupation. It makes two methodological contributions to the literature: contributing to the nascent interest in the media's construction of dirty work (e.g. Grandy and Mavin, 2012); and using rhetorical analysis to study the construction of taint.

The purpose of this paper is to explore the contentious issue whether lawyers become launderers when they accept dirty money as legal fees. Lawyers represent criminal defendants who may wish to pay for their legal fees with proceeds of their criminal activities. The paper analyses the legal position of Namibia and Zimbabwe on such tainted fees and proceeds to compare with the different position taken by the United States.

The paper adopts a desk research methodology with reliance on various sources such as statutory laws, case laws, books, journal articles and the internet. Its scope is limited to issue and content analysis relating to the use of dirty money as legal fees.

The paper shows that lawyers become launderers when they accept dirty money as legal fees with knowledge or suspicion of its origins. It concludes that the prohibition of dirty money as legal fees is important in the fight against economic crime in Namibia and Zimbabwe. Even though it is decriminalised in the USA, the continuous prosecution of lawyers for tainted fees shows that state authorities are aware of the dangers of tainted legal fees.

This paper adds to the few available literature on dirty money and legal fees. It provides sound reasons why prohibition of tainted attorneys’ fees adds muscle to the fight against economic crime. No prior literature is available on tainted legal fees in Namibia and Zimbabwe specifically.

Previous studies indicate that both health and taste are important factors in the food choice process. Owing to the industrialization of food processing and biotechnological innovations on the one hand and a series of food scandals on the other, consumers are now more concerned about modern food hazards. The present study aims to investigate whether consumers with varying degrees of modern tainted foods worries and gender difference will show variations in the Health and Taste Attitude Scales (HTAS).

Of a total of 1,500 questionnaires sent out, 533 were found useful for this empirical analysis. The measurement items of the Health and Taste Attitude Scale (HTAS) were scored as the data input to test for the impacts of modern tainted foods worries and gender by ANOVA tests.

The results of this study conducted in Taiwan indicate that those people identified in the ‘‘high modern tainted foods worries’’ group have more interests in health in foods but the ‘‘low modern tainted foods worries’’ group have more interests in taste in foods. In addition, though more concerned about health in foods, female consumers are also more interested in sweet foods.

Some suggestions for food marketers and food policy makers are also provided in this study.

To the best knowledge of this researcher, this study represents one of the first attempts to investigate the health and taste attitudes in Taiwan and tests for the impacts of modern tainted foods worries and gender.

The purpose of this paper is to present a unique model for the production–recycling–reuse of aluminium refreshment cans. It is presumed that disposed-off 250-ml aluminium cans are collected from the retail outlet. The cans are thereafter arranged into non-tainted and tainted categories.

The current model considers all the factors, i.e. producing, recycling and remanufacturing, whereas the previous models provide emphasis only one factor. Six procedures were considered in the improvement of the mathematical model.

In this paper, a recycling–reuse model that remanufactures non-tainted aluminium beverage cans and uses regrind from damaged non-tainted aluminium beverage cans mixed with parent aluminium material in the production of new cans was developed and analysed to reduce the amount of aluminium beverage cans that are disposed off in a scrapyard. The model is assumed to have no shortcomings, and the different percentages regarding the classes of cans are taken to be deterministic.

The model incorporates several unique aspects, including accounting for the cost of land use and associated environmental damage through the calculation of a present value that is charged to the manufacturer.

The purpose of this paper is to consider how taxi drivers understand the customer service relationship as “dirty work” by examining the strategies they use to manage the taint associated with their work.

An innovative qualitative approach is taken that focuses upon the analysis of metaphors elicited in interviews with 24 taxi drivers.

Four different metaphorical understandings of the customer service relationship are provided: heroes, confidante, the unworthy, and predator. These metaphors are explained through a series of “hidden transcripts” (Scott, 1990). The impact of these different metaphors and hidden transcripts as sensemaking devices is addressed.

The paper uses an innovative qualitative method to argue that the construction of work as “dirty” or otherwise is located within the customer service interaction.

The purpose of this paper is to explore career identity within the aged care sector.

The research employs a descriptive interpretive methodology using 32 in-depth, semi-structured interviews.

This paper shows that social processes and occupational and professional status issues shape career identity in an aged care context. Individuals seek positive career identities through emphasising job fit in relation to their personal experience and values in order to counteract the impact of “taint”.

This study was based in one organisation. Future research could explore its findings in the context of multiple organisations, and include the concept of career identity in other low status, “tainted” occupations, such as childcare, in order to develop a more complete understanding of identity construction processes.

The findings suggest that aged care providers could employ a values-driven approach to recruitment, complementary to pay and career development, to enhance recruitment and retention of aged care employees. Universities and professional bodies could consider more active use of aged care student placements to highlight the opportunities that aged care offer to new graduates in allied health professions.

This paper extends our understanding of career identity in relation to “taint” and “dirty work” in the context of two occupational groups in the understudied sector of aged care.

Repeat tourists are invaluable to tourist destinations. However, their perceptions and reactions toward unfavorable destination changes remain underexplored. This paper aims to answer two important and unresolved questions: how do repeat tourists react to perceived unfavorable changes? and what are the main unfavorable destination changes for repeat tourists?

This research builds on the strategic memory protection theory. This paper consists of two studies (a quantitative one and a qualitative one) conducted in China. The quantitative study proposed and tested a structural equation model linking perceived unfavorable changes, tainted memories, revisit satisfaction and destination loyalty. Data were collected via a questionnaire distributed on an online survey platform with 416 valid responses. The qualitative study was conducted to determine the unfavorable destination changes that repeat tourists perceive. Ninety-five valid responses were used for analysis.

This research empirically shows that perceived unfavorable changes diminish repeat tourists’ destination loyalty by tainting their initial memories and reducing revisit satisfaction. This full mediation confirms the importance of personal memories and psychology in tourism experiences. This research further uncovers two main types of unfavorable destination changes: destination mismanagement (i.e. overcommercialization, insufficient facilities, poor destination management, excessive prices and a decline in service qualities) and negative environmental changes (overtouristification, changes to natural and social environments and changes in tourist sites and activities).

This research adds to the destination loyalty literature by unveiling actual repeat tourists’ revisit perceptions and psychological processes toward unfavorable destination changes. This research also identifies the typical unfavorable changes perceived by repeat tourists.

重游游客对旅游目的地来说极其重要。然而, 他们对不利的目的地变化的看法和反应仍未得到充分探讨。本研究旨在回答两个重要且未解决的问题：重游游客如何对感知到的不利变化做出反应？ 对重游游客来说, 不利的目的地变化主要有哪些？

本研究以策略性记忆保护理论为理论基础, 包括两项在中国开展的研究（一项定量研究和一项定性研究）。定量研究提出并验证了一个将感知的不利变化、记忆破坏、重游满意度和目的地忠诚度相关联的结构方程模型。定量研究数据通过在线问卷平台收集, 共有 416份有效数据。定性研究的开展旨在确定重游游客所感知的不利目的地变化的类型, 共有95份有效访谈数据用于定性分析。

本研究通过实证分析表明, 感知到的不利变化会破坏重游游客最初的记忆和降低重游满意度, 进而降低了他们的目的地忠诚度。这种完全中介效应证实了个人记忆和心理在旅游体验中的重要性。本研究进一步揭示了两种主要的目的地不利变化类型：目的地管理不善（即过度商业化、设施不足、目的地管理缺位、价格过高、服务质量下降）和负面环境变化（过度旅游化、自然和社会环境变化、旅游景点和活动变化）。

本研究通过揭示真实的重游游客的重游感知和对不利目的地变化的心理过程, 丰富了目的地忠诚度研究的文献, 同时还总结了重游游客所感知的典型的不利的目的地变化的类型。

Los turistas que repiten son muy valiosos para los destinos turísticos. Sin embargo, sus percepciones y reacciones ante los cambios desfavorables en el destino han sido poco exploradas. Esta investigación tiene como objetivo responder dos preguntas importantes y no resueltas: ¿Cómo reaccionan los turistas que repiten un destino ante los cambios desfavorables percibidos? ¿Cuáles son los principales cambios desfavorables en el destino para los turistas que repiten?

Esta investigación se fundamenta en la teoría de la protección estratégica de la memoria. Consta de dos estudios (uno cuantitativo y otro cualitativo) realizados en China. El estudio cuantitativo propuso y evaluó un modelo de ecuación estructural que vincula los cambios desfavorables percibidos, los recuerdos contaminados, la satisfacción de la revisita y la lealtad al destino. Los datos se recopilaron a través de un cuestionario distribuido en una plataforma de encuestas en línea con 416 respuestas válidas. El estudio cualitativo se realizó para determinar los cambios desfavorables en el destino que perciben los turistas. Se utilizaron noventa y cinco respuestas válidas para el análisis.

Esta investigación demuestra empíricamente que los cambios desfavorables percibidos disminuyen la lealtad de los turistas que repiten un destino, al empañar sus recuerdos iniciales y reducir la satisfacción de la revisita. Esta mediación total confirma la importancia de los recuerdos personales y la psicología en las experiencias turísticas. Esta investigación descubre, además, dos tipos principales de cambios desfavorables en el destino: mala gestión del destino (es decir, comercialización excesiva, instalaciones insuficientes, mala administración, precios excesivos y disminución de la calidad del servicio) y cambios ambientales negativos (turistificación excesiva, cambios en los entornos naturales y sociales, y cambios en los sitios y actividades turísticas).

Esta investigación contribuye a la literatura sobre la lealtad al destino, al desvelar las percepciones de los turistas que repiten visita, y sus procesos psicológicos hacia los cambios desfavorables en los destinos. También identifica los cambios desfavorables típicos percibidos por los turistas que vuelven a un destino.

Problems with corks are a major issue in the wine industry. The key problem has been the lack of consumer acceptance of alternative closures. This research used an interview and survey approach with 200 wine shoppers in Australia to determine: 1) consumer perceptions of cork problems; 2) acceptance of a synthetic cork with no information provided; and 3) acceptance of a synthetic cork after providing information concerning cork problems and solutions. Consumers who purchased more than one bottle of wine per week had the most problems with corks, but 75% of all consumers interviewed had experienced some problems in the last 12 months. The provision of information was key in gaining consumer acceptance of the synthetic corks. Measures of which attributes of the synthetic corks attracted consumers is also provided along with recommendations for introducing these closures into the marketplace.
