A Simple Model of Secure Public Communication

Public communication is secure if a hostile third-party cannot decode the messages exchanged by the communicating parties. In Nash equilibrium, communication by computationally unbounded players cannot be secure. We assume complexity averse players, and show that a simple, secure, and costless communication protocol becomes available as the marginal complexity cost tends to zero.      

The Right to Remain Silent

The paper points out that in dynamic games a player may be better-off if other players do not know his choice of strategy. That is, a player may benefit by not revealing (or not pre-determining) the choice of his action in an information set he (thereby) hopes will not be reached. He would be better-off by exercising his ``right to remain silent' if he believes –- as the empirical evidence shows –- that players display aversion to ``Knightian uncertainty'. In this case, a player who behaves strategically, may wish to avoid revealing his strategy. This is true under various interpretations of the notion of ``strategy profiles'.     

Parent–Child Emotional Communication and Children's Coping in Middle Childhood

Parent–child communication regarding children's negative emotions and coping were examined in a sample of 75 5th graders (53% boys) and their mothers and fathers. We predicted that emotionally open communication between a parent and his or her child would be related to children's use of constructive coping strategies. Parents reported on how they react to their child's negative emotions, and children reported on how much they share their negative feelings with each parent. Additionally, emotional communication was measured during a parent–child discussion task involving an event that was upsetting to the child. The results indicated that emotional communication, as reported by mothers, fathers, and children, as well as mother–child observed communication, were related to children's coping strategies. The findings point to a need to assess emotional communication using multiple measures that tap both the child's and the parents’ perspectives and that use different methodologies.     

How to consult an expert? Opinion versus evidence

In this article, two modes of non-binding communication between an expert and a decision-maker are compared. They are distinguished mainly by the nature of the information transmitted by the expert. In the first one, the expert reports only his opinion (soft information) concerning the desirability of a certain action, whereas in the second one, he is consulted to provide evidence (hard information) to convince the decision-maker. The expert’s ability to provide evidence increases with the precision of his information. The article shows that requiring evidence is always beneficial to the decision-maker whereas it is beneficial to the expert, if and only if the preferences of both agents are different enough.     

Identification of a princess under incomplete information: an amarna story

This article presents four analyses of an interaction between the middle-Bronze Age Pharaoh Nibmuarea and the Babylonian king Kadashman-Enlil as described in the Amarna letters (Moran [1992] The Amarna Letters, The Johns Hopkins Universiy Press, Baltimore, Maryland). Intent on denying the Pharaoh his daughter in marriage, the Babylonian king was faced with the choice of sending messengers who could ('dignitaries') or could not identify ('non-dignitaries') his missing sister in the Pharaoh's court. Intent on marrying the king's daughter, the Pharaoh was faced with the choice of showing the sister or showing someone else. Based on the assumption of complete information (game 1), the analysis revealed a dominant-strategy equilibrium: Nibmuarea shows the sister and Kadashman-Enlil sends non-dignitaries. Based on the assumption of one-sided incomplete information (Pharaoh's misperception; game 2), the analysis revealed that the Pharaoh had a dominant strategy of showing the sister irrespective of whether the king is keen or reluctant to learn about his sister's fate. Based on the assumption of one-sided incomplete information (Kadashman-Enlil's misperception; game 3), the analysis revealed that if non-dignitaries are sent, the Pharaoh prefers showing someone other than his sister. Based on the assumption of two-sided incomplete information (game 4), the Pharaoh finds it more beneficial to present the sister irrespective of whether his intentions are genuine or feigned. With incomplete information, it is difficult to judge the other's intentions; the cost of being caught cheating by not showing the sister to knowledgeable messengers was quite high. These analyses highlight the strategic uncertainty that characterized this Bronze-Age interaction.     

Uncommon Priors Require Origin Disputes

In standard belief models, priors are always common knowledge. This prevents such models from representing agents’ probabilistic beliefs about the origins of their priors. By embedding standard models in a larger standard model, however, pre-priors can describe such beliefs. When an agent’s prior and pre-prior are mutually consistent, he must believe that his prior would only have been different in situations where relevant event chances were different, but that variations in other agents’ priors are otherwise completely unrelated to which events are how likely. Due to this, Bayesians who agree enough about the origins of their priors must have the same priors.     

The scrapbooking detective: Frederick Porter Wensley and the limits of ‘celebrity’ and ‘authority’ in inter-war Britain

Frederick Porter Wensley was one of Scotland Yard's ‘Big Four’ detectives, head of the Metropolitan Police Criminal Investigation Department and responsible for establishing the Flying Squad. On his retirement in 1929, he used the two bound scrapbooks of press clippings and photographs he had collated to document his personal life and career to inform his 1931 autobiography Detective Days and serialized press articles. Through examining the interaction of material between scrapbooks and autobiographical writings, this article explores how Wensley constructed his post-retirement persona as ‘celebrity detective’ from a canny understanding of what had made him a commercial subject for the press. It argues that Wensley recast his life to promote his own successes at the expense of a narrative of police unity, providing a vehicle for him to suggest further changes to the structure of the police force without official sanction. By juxtaposing this against tightening legislation on police communication with journalists during the inter-war period under the Official Secrets Acts, this article demonstrates how the ‘celebrity’ that Wensley sought to occupy was increasingly regarded as irreconcilable with police ability to effect ‘impartial’ regulation, anticipating the concerns raised by the 2012 Leveson Inquiry into the Culture, Practice and Ethics of the Press. The article thus charts a turning point in defining the relationship between police and press.     

Changing preferences towards redistribution: How deliberation shapes welfare attitudes

The article departs from the argument that research on welfare attitudes is, so far, dominated by large‐scale survey‐studies, which allow for generalizable insights into citizens' preferences and evaluations, but are necessarily limited in their ability to capture the dynamic and contextual aspects of attitude formation. In order to broaden the horizon of welfare attitudes' research, this article introduces a new qualitative method, namely deliberative forums. In these large group discussions—originally developed for participatory decision‐making—attitudes, opinions, and preferences are core aspects of the deliberation process, and the article argues that by observing deliberation, we can observe attitude construction “in vivo ”. The evidence from a two‐day German deliberation event illustrates in an exploratory manner how information, reasoning, and group processes can influence people's evaluations and expressed policy preferences with regard to redistribution. By linking participants' answers from a survey before and after the event to their statements during the discussions, the article not only shows that the preferences for redistribution people expressed in the survey answers are often higher after the deliberative event, but also seeks to make sense of attitudinal dynamics on the basis of the qualitative material by pointing towards the role of information, reasoning, and group processes.     

Climate Change Communication: Examining the Social and Cognitive Barriers to Productive Environmental Communication

Objectives. This study explores the efficacy of visual appeals that may be used to communicate environmental risk.Methods. To better understand the social and cognitive barriers present in environmental risk communication associated with climate change, we conducted a series of six focus groups. Groups were asked to view images of environmental issues and select the best representation of their feelings out of a range of preselected emotions. While further research is required, preliminary investigation based on the focus groups suggests several themes. Results. First, an individual's familiarity with both an area and an event will decrease the individual's perception of urgency; conversely, the participants expressed greater concern for events that were local and new—in other words, familiarity diminishes urgency, while emergent problems create alacrity. Second, participants expressed a sentiment of tacit blame, in which the participant's own contribution to the issue received less emphasis when ascribing fault. Last, the participants reacted positively toward messages that emphasized a hopeful and solution-based narrative and were seemingly less motivated by images that relied on fear-based messaging. Conclusions. Preliminary findings suggest that hopeful, solution-based messaging may be more effective in facilitating pro-environmental behavior than either fear- or guilt-based appeals.     

Symbols of Terror: ‘9/11’ as the Word of the Thing and the Thing of the Word

This paper adopts a social representations approach to examine the ‘9/11’ symbol which is argued to be a centrally organising, communication oriented, symbolic resource within contemporary representations of terrorism. Within the context of the events of September 11 2001 as a point of shared history which has come to be understood as a significant world event (Liu et al., 2009 ), the ‘9/11’ symbol is argued to fulfil a triple function in contemporary representations of terrorism. Firstly, the ‘9/11’ symbol provides a central anchor for the events of September 11 2001. Secondly the ‘9/11’ symbol acts as a powerful rhetorical resource for objectifying the abstract concept of terrorism. Lastly, alongside the capacity to objectify the abstract, the ‘9/11’ symbol also enables a counter process of transcendentalisation (Billig, 1988 ) whereby it transforms the object into the abstract. As a result the ‘9/11’ symbol is highly suited to widespread mobilisation of easily apprehended notions defining what terrorism is, which do not readily provoke contest and are widely constructed as mundane forms of ‘truth’ amongst a community of users.     

Identity reconstruction as shiduers: Narratives from Chinese older adults who lost their only child

The purpose of this qualitative study was to illustrate how the identity of Chinese older adults who lost their only child changed after the traumatic event in the context of unique culture and policy settings. The individuals studied were 14 adults over the age of 50. Each respondent was interviewed concerning his or her post‐loss experiences. Results indicated that these bereaved parents are not only deeply impacted by the loss of the most loved one, but are also stigmatized by the culture and victimized by the one‐child policy. The collective identity as shiduer is defined not only by personal grief but also by cultural uniqueness and the unintended consequences of the one‐child policy.     

Literature and the Arts

The author reviews The Revolutionary Romanticism of Shelley, a critical biography by I. Neupokoeva (Goslitizdat, Moscow, 1959, 470 pp.) which shows the poet as a child of his age and relates his creative output to his social as well as his esthetic views. Literaturnaya Gazeta, 1961, No. 3.     

Does It Matter if Preschool Children and Mothers Discuss Positive vs. Negative Events During Reminiscing? Links with Mother‐reported Attachment,Family Emotional Climate,and Socioemotional Development

The purpose of the study was to examine the differential relations between mother–child reminiscing about a positive emotional event vs. a negative emotional event and attachment security, family climate, and young children's socioemotional development. Fifty preschool children (M age = 50.69 months, SD = 4.64) and their mothers completed two reminiscing conversations at the laboratory, which were coded for emotion‐laden discourse, affect, and elaboration, and children completed measures of emotional understanding and representations of relationships. At their homes, mothers completed the attachment Q‐sort and the self‐report family inventory. Both attachment security and family climate were related to the quality of mother–child affect and maternal elaboration during both positive and negative reminiscing conversations. Attachment security and family climate, however, were principally related to discussion of emotion during the negative event discussions. In addition, it was mother–child reminiscing about the negative emotional event that was associated with high levels of children's socioemotional development.     

‘It's always a battle against time’. Experiencing and handling temporal conditions in homecare work

In most Western countries, the eldercare sector has undergone transformations to obtain cost containment and more efficient service provision, changing the temporal framing of homecare. Time pressure is a salient issue in homecare, but little is known about how homecare workers experience the temporal conditions of their work. Based on 13 group interviews with homecare workers in Sweden, this study examined how the staff experience temporal conditions and handle time pressure in their everyday work in a context of marketisation and increased use of ‘information and communication technology’. The analysis showed that the workers attributed their experiences of time pressure to the compression of time, the control of time and the unpredictability of time. Strategies adopted to handle time pressure included working unpaid hours, maximising efficiency and reallocating time. It is concluded that the homecare workers primarily adopted individual short-term strategies to deal with structural and organisational temporal issues.     

Making Low Probabilities Useful

This paper explores how people process information on low probability-high consequence negative events and what it will take to get individuals to be sensitive to the likelihood of these types of accidents or disasters. In a set of experiments, information is presented to individuals on the likelihood of serious accidents from a chemical facility. Comparisons are made with other risks, such as fatalities from automobile accidents, to see whether laypersons can determine the relative safety of different plants. We conclude that fairly rich context information must be available for people to be able to judge differences between low probabilities. In particular, it appears that one needs to present comparison scenarios that are located on the probability scale to evoke people's own feelings of risk. The concept of evaluability recently introduced by Hsee and his colleagues provides a useful explanation of these findings.     

Go to the Hospital or Stay at Home? A Qualitative Study of Expected Hospital Decision Making Among Older African Americans With Advanced Heart Failure

To address the need for more information concerning hospital decision making, we conducted in-depth interviews among African Americans with heart failure and their family caregivers (n?=?11 dyads). Using a case scenario, we asked participants about their anticipated hospitalization decisions. Most patients indicated that they would seek care to avoid further deterioration or death from their worsening condition. Many family caregivers anticipated having an active influence on hospitalization decisions. Findings suggest that social workers should encourage the development of adequate home-based services, recognize diverse communication styles, and use this information to facilitate medical decision making by these patients and their caregivers.     

The Social as Heaven and Hell: Pierre Bourdieu's Philosophical Anthropology

Many authors have argued that all studies of socially specific modalities of human action and experience depend on some form of “philosophical anthropology”, i.e. on a set of general assumptions about what human beings are like, assumptions without which the very diagnoses of the cultural and historical variability of concrete agents' practices would become impossible. Bourdieu was sensitive to that argument and, especially in the later phase of his career, attempted to make explicit how his historical‐sociological investigations presupposed and, at the same time, contributed to the elaboration of an “idea of the human being”. The article reconstructs Bourdieu's philosophical anthropology, starting with his genetic sociology of symbolic power, conceived as a form of critical theory (latu sensu), and concluding with an account of the conditio humana in which recognition (“symbolic capital”) appears as both the fundamental existential goal through which human agents strive to confer meaning on their lives and the source of the endless symbolic competition that keeps society moving. The agonistic vision of the social universe that grounds his sociological studies returns in his philosophical anthropology under the guise of a singular synthesis between Durkheim's thesis that “Society is God” and Sartre's idea that “hell is other people”.     

HIV and PTSD: A Confirmatory Factor Analysis of the PCL Screening Instrument

ABSTRACT

The findings are reported from a confirmatory factor analysis (CFA) of the posttraumatic screening checklist (PCL) created by Weathers et al. (1993) Weathers, F. W., Litz, B. T., Herman, D. S., Huska, J. A. and Keane, T. M. 1993. The PTSD Checklist (PCL): Reliability, validity, and diagnostic utility, Presented at Annual Meeting of the International Society for Traumatic Stress Studies, San Antonio, TX. [Google Scholar]. One hundred and eighty-six individuals receiving either preventive HIV information or ongoing HIV counseling from community-based AIDS organizations in the New York City area completed the PCL checklist. To identify a model relevant to screening posttraumatic stress disorder (PTSD) within the HIV/AIDS community, six CFAs were conducted. Results indicated that the PTSD scale should include attention to four general areas: a) reexperiencing the traumatic event; b) avoidance of anything associated with the traumatic event; c) a sense of numbing; and d) a hyperarousal state. The CFA produced a more concise model of 12 items, relevant to the HIV community. Future research suggests that the relationships between different components of trauma exposure and different manifestations of PTSD should be examined further.     

A Rule For Updating Ambiguous Beliefs

When preferences are such that there is no unique additive prior, the issue of which updating rule to use is of extreme importance. This paper presents an axiomatization of the rule which requires updating of all the priors by Bayes rule. The decision maker has conditional preferences over acts. It is assumed that preferences over acts conditional on event E happening, do not depend on lotteries received on E ^c, obey axioms which lead to maxmin expected utility representation with multiple priors, and have common induced preferences over lotteries. The paper shows that when all priors give positive probability to an event E, a certain coherence property between conditional and unconditional preferences is satisfied if and only if the set of subjective probability measures considered by the agent given E is obtained by updating all subjective prior probability measures using Bayes rule.     

Welfare Governance in the Surveillance Society: A Positive-Realistic Cybercriticalist View

In exploring the implications of information and communication technologies (ICTs), Fitzpatrick has suggested the need for a new category of rights—virtual rights. To explore this claim, we consider how developments in information management and processing differentially impact on citizens. Using examples from the public and private sectors we explore the dangers posed by the emergent surveillance society and agree these may require new rights. But we suggest that the state has by no means been an exemplar and, moreover, that many of the “surveilling” practices employed by commercial organizations might be used by the state to pursue socially just ends. We argue against a criticalist perspective that narrowly focuses on the dangers posed by new ICTs. Indeed, from a realist perspective we argue that a positive cybercriticalism that seeks to tackle exclusion by harnessing and constraining the surveillance qualities of ICTs is a pressing policy priority.
