This paper aims to broaden the present CSR literature by extending its focus to the absence of CSR within a developing country, an area which, to date, is relatively under researched in comparison to the more widely studied presence of CSR within developed Western countries. In particular this paper concentrates upon the lack of disclosure on three particular eco-justice issues: child labour, equal opportunities and poverty alleviation. We critically examine why this is the case and thereby illuminate underlying motives behind corporate unwillingness to address these issues. For this purpose, 23 semi-structured interviews were undertaken with senior corporate managers in Bangladesh. The findings suggest that the main reasons for non-disclosure include lack of legal requirements, lack of knowledge/awareness, poor performance and fear of bad publicity. Given these findings the paper raises some serious concerns as to why corporations would ever be expected to voluntarily report on eco-justice issues where performance is poor and negative publicity would be generated. These significant issues require careful consideration by policy makers at the national, regional and international levels.

In Europe local authorities often work with their neighbouring municipalities, whether to address a specific task or goal or through the course of regular policy making and implementation. In England, however, inter-municipal co-operation (IMC) is less common. Councils may work with service providers from the private and non-profit sectors but less often with neighbouring local authorities. Why this is the case may be explained by a number of historical and policy factors that often encourage councils to compete, rather than to work collaboratively with each other. The present government has encouraged councils to work in partnership with other organizations but there are few examples of increased horizontal cooperation between local authorities. Instead the prevailing model remains fixed on vertical co-working predicated on a principal-agent relationship between higher and lower tiers of government.

The number, diversity and restriction enzyme fragmentation patterns of plasmids harboured by 44 multidrug-resistant hospital-acquired methicillin-resistant Staphylococcus aureus (MR-HA-MRSA) isolates, two multidrug-resistant community-acquired MRSA (MR-CA-MRSA), 50 hospital-acquired MRSA (HA-MRSA) isolates (from the University Hospital Birmingham, NHS Trust, UK) and 34 community-acquired MRSA (CA-MRSA) isolates (from general practitioners in Birmingham, UK) were compared. In addition, pulsed-field gel electrophoresis (PFGE) type following SmaI chromosomal digest and SCCmec element type assignment were ascertained for each isolate. All MR-HA-MRSA and MR-CA-MRSA isolates possessed the type II SCCmec, harboured no plasmid DNA and belonged to one of five PFGE types. Forty-three out of 50 HA-MRSA isolates and all 34 CA-MRSA isolates possessed the type IV SCCmec and all but 10 of the type IV HA-MRSA isolates and nine CA-MRSA isolates carried one or two plasmids. The 19 non-multidrug-resistant isolates (NMR) that did not harbour plasmids were only resistant to methicillin whereas all the NMR isolates harbouring at least one plasmid were resistant to at least one additional antibiotic. We conclude that although plasmid carriage plays an important role in antibiotic resistance, especially in NMR-HA-MRSA and CA-MRSA, the multidrug resistance phenotype from HA-MRSA is not associated with increased plasmid carriage and indeed is characterised by an absence of plasmid DNA. © 2005 Federation of European Microbiological Societies.

Using a new optical configuration free from the influence of photorefractive optical nonlinearity, we investigate the main characteristics of the spatial subharmonic K/2 excited in a Bi12SiO20 crystal by a light-intensity pattern with wave vector K and frequency O. It is shown that in a large region of intensity and applied electric field the optimum value O of the frequency corresponds to the conditions of parametric excitation of the weakly damped eigenmodes of the medium: the space-charge waves. The threshold and above-threshold characteristics of the subharmonic regime are in good agreement with the theory.

Garner seeks to explain the absence of far-right political formations in the history of the Republic of Ireland, especially in relation to immigration. He argues that the ‘mainstream’ nationalist parties have implemented a racialized governance of Ireland via the issue of citizenship (in the referendum of 2004). While hegemonic ideas on the racial purity of indigenous populations and the highly ambivalent attitudes and policies on immigration pursued over the last decade are characteristic of a broader European trend, this has not, in the Republic, been accompanied by meaningful far-right political mobilization. Ireland has frequently been seen as sui generis in political terms, and indeed emerges in some ways as a counter-case: increasing hostility towards Others has been identified in the midst of rapid economic growth and political stability. A variety of issues related to the country’s political development have given rise to an especially small left-wing vote, a nationalist centre ground and longlasting domination by a single populist party, Fianna Fa´ il. This party has been partnered in government since 1997 by a free-market party, the Progressive Democrats, who have contributed to Ireland’s movement towards neo-liberal policies and a highly functional approach to immigration. The transition from country of emigration to country of immigration has thus taken place against an ideological backdrop in which the imperatives of labour demand and consolidating domestic support for reform have made an uneasy match, resulting in the racialization of Irishness. The state has, however, amended the Constitution in order to qualify jus soli citizenship entitlement in the case of particular categories of people: those whose parents are not Irish nationals. The significant stakes of these changes are analysed in the context of state responses to Eire’s transition to a country of immigration, and the role of nationalist-populism in the country’s political culture.

Using a new experimental geometry, we have proved for the first time that the generation of spatial subharmonic gratings in photorefractive crystals is not dependent on optical nonlinearity. We present results which confirm that the subharmonic gratings result from a parametric excitation of ultra low-frequency eigenmodes of a crystal by a time modulated fundamental grating.

Globally, more than 1000 tonnes of titanium (Ti) is implanted into patients in the form of biomedical devices on an annual basis. Ti is perceived to be ‘biocompatible’ owing to the presence of a robust passive oxide film (approx. 4 nm thick) at the metal surface. However, surface deterioration can lead to the release of Ti ions, and particles can arise as the result of wear and/or corrosion processes. This surface deterioration can result in peri-implant inflammation, leading to the premature loss of the implanted device or the requirement for surgical revision. Soft tissues surrounding commercially pure cranial anchorage devices (bone-anchored hearing aid) were investigated using synchrotron X-ray micro-fluorescence spectroscopy and X-ray absorption near edge structure. Here, we present the first experimental evidence that minimal load-bearing Ti implants, which are not subjected to macroscopic wear processes, can release Ti debris into the surrounding soft tissue. As such debris has been shown to be pro-inflammatory, we propose that such distributions of Ti are likely to effect to the service life of the device.

Mistuning a harmonic produces an exaggerated change in its pitch, a component-pitch shift. The origin of these pitch shifts was explored by manipulations intended to alter the grouping status of a mistuned target component in a periodic complex tone. In experiment 1, which used diotic presentation, reinstating the corresponding harmonic (in-tune counterpart) caused the pitch shifts on the mistuned target largely to disappear for components 3 and 4, although they remained for component 2. A computational model of component-pitch shifts, based on harmonic cancellation, was unable to explain the near-complete loss of pitch shifts when the counterpart was present; only small changes occurred. In experiment 2, the complex tone and mistuned component 4 were presented in the left ear and the in-tune counterpart was presented in the right. The in-tune counterpart again reduced component-pitch shifts, but they were restored when a captor complex into which the counterpart fitted as harmonic 3 was added in the right ear; presumably by providing an alternative grouping possibility for the counterpart. It is proposed that component-pitch shifts occur only if the mistuned component is selected to contribute to the complex-tone percept; these shifts are eliminated if it is displaced by a better candidate.

This paper aims to broaden the present corporate social responsibility (CSR) reporting literature by extending its focus to the absence of CSR reporting within a developing country, an area which, to date, is relatively under researched in comparison to the more widely studied presence of CSR reporting within developed Western countries. In particular this paper concentrates upon the lack of disclosure on three particular eco-justice issues: child labour, equal opportunities and poverty alleviation. We examine why this is the case and thereby illuminate underlying motives behind corporate unwillingness to address these issues. For this purpose, 23 semi-structured interviews were undertaken with senior corporate managers in Bangladesh. The findings suggest that the main reasons for non-disclosure include lack of resources, the profit imperative, lack of legal requirements, lack of knowledge/awareness, poor performance and the fear of bad publicity. Given these findings the paper raises some serious concerns as to why corporations would ever be expected to voluntarily report on eco-justice issues where performance is poor and negative publicity would be generated and profit impaired. Further research is still required to uncover current injustices and to imagine what changes can be made.

We are interested in the annotation of knowledge which does not necessarily require a consensus. Scholarly debate is an example of such a category of knowledge where disagreement and contest are widespread and desirable, and unlike many Semantic Web approaches, we are interested in the capture and the compilation of these conflicting viewpoints and perspectives. The Scholarly Ontologies project provides the underlying formalism to represent this meta-knowledge, and we will look at ways to lighten the burden of its creation. After having described some particularities of this kind of knowledge, we introduce ClaimSpotter, our approach to support its ‘capture’, based on the elicitation of a number of recommendations which are presented for consideration to our annotators (or analysts), and give some elements of evaluation.

The paper has raised some serious public policy concerns by exploring the underlying motives for absence of CSR in general and some eco-justice issues in particular (e.g. child labour, equal opportunities and poverty alleviation). These significant issues require careful consideration by the policy makers at the national, regional and international levels.

Previous research suggests that parental controlling feeding practices are associated with children's overeating and undereating behaviours. However, there is limited research addressing the link between children's mental health symptoms (specifically anxiety and depression) and their reports of eating behaviours, despite knowledge that these psychopathologies often co-exist. The current study aimed to identify the relationships between preadolescents' perceptions of their parents' feeding practices with reports of their own anxiety, depression and eating behaviours. Three hundred and fifty-six children (mean age 8.75 years) completed questionnaires measuring their dietary restraint, emotional eating and external eating, as well as their perceptions of their parents' use of pressure to eat and restriction of food. Children also completed measures of general anxiety, social anxiety and depression symptomology. Results indicated that preadolescents' eating behaviours were associated with their perceptions of the controlling feeding practices their parents used with them. Preadolescents' dietary restraint, emotional eating and external eating behaviours were positively associated with their reports of general and social anxiety, and depression symptomology. In addition, perceptions of parental pressure to eat were positively related to preadolescents' anxiety and depression levels. Child anxiety (general and social) was found to mediate the relationship between perceptions of parental pressure to eat and preadolescents' eating behaviours (dietary restraint, emotional eating and external eating). The results suggest that greater anxiety in preadolescents may explain why children who perceive greater pressure to eat by their parents are more likely to exhibit maladaptive eating behaviours. © 2014 Elsevier Ltd.
