Relational semantics for full linear logic

Relational semantics, given by Kripke frames, play an essential role in the study of modal and intuitionistic logic. In [4] it is shown that the theory of relational semantics is also available in the more general setting of substructural logic, at least in an algebraic guise. Building on these ideas, in [5] a type of frames is described which generalise Kripke frames and provide semantics for substructural logics in a purely relational form.In this paper we study full linear logic from an algebraic point of view. The main additional hurdle is the exponential. We analyse this operation algebraically and use canonical extensions to obtain relational semantics. Thus, we extend the work in [4], [5] and use their approach to obtain relational semantics for full linear logic. Hereby we illustrate the strength of using canonical extension to retrieve relational semantics: it allows a modular and uniform treatment of additional operations and axioms.Traditionally, so-called phase semantics are used as models for (provability in) linear logic [8]. These have the drawback that, contrary to our approach, they do not allow a modular treatment of additional axioms. However, the two approaches are related, as we will explain.     

‘The Good Mother and Her Clinging Child’: Patterns of Anchoring in Social Representations of Dementia Caregiving

This paper discusses the findings of a study that examined the processes of anchoring in the understanding of dementia caregiving using 29 interviews conducted in Germany with wives and daughters caring for a relative with dementia and 43 newspaper articles pertinent to the research objective. The concept of anchoring from Social Representations Theory was complemented by elements from cognitive linguistics to analyse the social representations (SRs) that served as source domains to determine what the target domain of dementia caregiving means, entails and requires. The analysis revealed three prevalent patterns of anchoring dementia care in SRs of child care and the good mother. The first pattern ascribed the role of the helpless clinging child needing his mother to the dementia patient, the second emphasised that the dementia caregivers' responsibility for caring, just like motherhood, should take precedence over all other interests and the third consisted of dementia caregivers deriving the perception of being the most suitable caregiver from the mother's natural aptitude for caring. The conclusions reached by the different patterns are argued to contribute to dementia caregivers overexerting themselves and not using support services. The clinical implications for targeting such adverse effects of the anchoring will be discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Representations of Poverty in British Newspapers: A Case of ‘Othering’ the Threat?

The meanings of social problems like poverty develop within the public sphere. This paper uses the theory of social representations to examine how poverty is represented in British newspapers. Poverty has been discussed and interpreted in numerous ways, and newspapers not only provide a platform for these elaborations but also contribute to shaping public understanding on the issue. The study sampled news coverage on poverty in four British newspapers during two randomly chosen one‐month periods in the years 2001 and 2011. The data set of news reports (n = 274) was thematically analysed to examine representations of poverty. The study found that in the domestic context, media represents poverty as a problem limited to vulnerable groups such as children and the elderly. With a lack of discussion on the wider socio‐economic causes and contributing factors, poverty within the UK appears as an ‘orphan phenomenon’ with an unknown genesis. In contrast, the representations of poverty outside the UK are vivid and elaborate, and the news reports hold the socio‐political inefficiency of countries responsible for poverty. The study also found that the media uses poverty to make sense of catastrophic events in society: the September 11, 2001 terrorist attacks in the United States and the London riots of 2011 were both anchored using poverty. This paper discusses the representational dynamics of these findings and argues that the media representations distance general society from poverty, representing it as a problem of the other.

Action representations activated by task‐irrelevant information: Is it really irrelevant?

Accessing action knowledge is believed to rely on the activation of action representations through the retrieval of functional, manipulative, and spatial information associated with objects. However, it remains unclear whether action representations can be activated in this way when the object information is irrelevant to the current judgment. The present study investigated this question by independently manipulating the correctness of three types of action‐related information: the functional relation between the two objects, the grip applied to the objects, and the orientation of the objects. In each of three tasks in Experiment 1, participants evaluated the correctness of only one of the three information types (function, grip or orientation). Similar results were achieved with all three tasks: “correct” judgments were facilitated when the other dimensions were correct; however, “incorrect” judgments were facilitated when the other two dimensions were both correct and also when they were both incorrect. In Experiment 2, when participants attended to an action‐irrelevant feature (object color), there was no interaction between function, grip, and orientation. These results clearly indicate that action representations can be activated by retrieval of functional, manipulative, and spatial knowledge about objects, even though this is task‐irrelevant information.     

Callous–unemotional traits and empathy in proactive and reactive relational aggression in young women

Research on psychopathy and aggression in women is limited, especially relational aggression (RA). Studies on youth suggest unique associations between RA and callous–unemotional (C–U) traits (e.g., Frick & White, 2008). However, the role of C–U traits in adult RA remains unexamined, particularly functional subtypes of RA (reactive, proactive). Empathy deficits are associated with C–U traits and heightened RA. Based on prior work, we hypothesized that in young women, callous and uncaring tendencies would be related to proactive RA and to a lesser extent reactive RA, and that these relationships would be mediated by cognitive empathy deficits. Hypotheses were partially supported. Callous and uncaring traits were associated with proactive RA, and less so to reactive RA, and the latter association was mediated by cognitive empathy. Unemotional traits were not uniquely associated with RA. Study limitations and implications are considered.     

Représentations sociales de la personne obèse et de l’obésité : effets de la situation de contact

This paper introduces a study about social representations of obese people and obesity. Two hundred normal-weighted women divided in two groups (presence vs absence of contact with an obese person) completed a word association tasks with inductive words “obese people” and “obesity”. Two instructions were proposed: one in which they responded for themselves (standard instruction) and another in which they responded for someone else (substitution instruction). Results of the Correspondences Factor Analysis support the hypothesis of an intergroup contact effect on the explored social representations’ organization. Participants in contact with obese people seem to have a more empathetic representation than those who have no contact. Indeed, when participants did not respond for themselves, counter-normative representations were produced: stereotypical elements and a judgment on the physical characteristics were expressed. These results were discussed regarding theories of intergroup contact and of social representations.     

One ring to rule them all: Master discourses of enlightenment—and racism—from colonial to contemporary New Zealand

We interrogated historical continuity and change in discourses of enlightenment and racism through the analysis of 160 years of New Zealand Speeches from the Throne (1854–2014, 163 speeches). Enlightenment discourses of benevolence and perfectibility were prevalent in all periods, much more so than racism. ‘Old‐fashioned’ racism took the form of an assumed civilizational superiority (including accusations of ‘barbarism’) during colonization, with ‘modern’ racism taking forms like blaming Māori for not ‘productively’ using the land. Both declined to almost zero by the 20th century, undermining the idea of ‘old‐fashioned’ versus ‘modern’ racism. Utilitarian discourses peaked in the late 19th to early 20th centuries as justification for Māori land alienation. ‘Master discourses of enlightenment’ consisted of a central core of social representations that changed at the periphery, with a gradual expansion of symbolic inclusion of Māori in discourses of national identity to the point where biculturalism is the dominant discourse for elites today.
