Is the Future more or less Human? Differing Views of Humanness in the Posthumanism Debate

A debate has emerged in the bioethics literature about the use of biotechnology to modify human nature. A failure to define humanness has produced conceptual confusion in this debate. We draw upon recent social psychological work on folk concepts of humanness and dehumanization to analyse the understandings of humanness that underpin the rival positions. We argue that advocates and opponents of human nature modification employ distinct conceptions of humanness, and that their differing evaluations of modification make sense in light of these conceptions. Advocates view modification as the enhancement of a non‐essentialist sense of humanness that takes us further from animal nature. Opponents view it as the loss of an essentialist sense of humanness that takes us closer to a robotic state. Recognition that humanness has multiple senses implies that there is no mutually exclusive choice between seeing the outcome of modification as a quantitative gain in humanness or a fundamental, qualitative loss of it.     

DECOMPOSING TRENDS IN INCOME VOLATILITY: THE “WILD RIDE” AT THE TOP AND BOTTOM

We use 2‐year panels from the Current Population Survey to provide a detailed accounting of family income volatility from 1980 to 2009. Volatility doubled overall, and the increase was most pronounced among the top 1% of the income distribution, but in any given year the level of volatility among the bottom 10% exceeds that of the top. The increased volatility comes from higher instability of head and spouse earnings, other nonlabor income, and from reduced covariance between these income sources with the tax system. This suggests that current tax policy is less effective in mitigating income shocks than previous decades. (JEL J31, I30)     

THE STATE STREET MILE: AGE AND GENDER DIFFERENCES IN COMPETITION AVERSION IN THE FIELD

Gender differences in “competitiveness,” previously documented in laboratory experiments, are hypothesized to play a role in a wide array of economic outcomes. This paper provides evidence of competition aversion in a natural setting somewhere between the simplicity of a laboratory experiment and the full complexity and ambiguity of a labor market. The “State Street Mile” race offers both male and female participants a choice between two different levels of competition. Large, systematic age and gender differences are observed in the relationship between true ability and the decision to enter the more competitive race. Overall, qualified women and older runners are far less likely than qualified young men to enter a competitive race with prizes. However, the fastest young women unanimously enter the competitive race. Therefore, while we confirm age and gender differences in competitiveness in our field setting, the economic consequences to capable young women are rather small. (JEL J1, J7, M5)     

On the Contingent Valuation of Safety and the Safety of Contingent Valuation: Part 2 - The CV/SG "Chained" Approach

This article reports the results of a study aimed at estimating a willingness-to-pay based value of statistical life for road risks using a multi-stage approach which involves "chaining together" responses to contingent valuation and standard gamble questions.The rationale for employing a multi-stage approach is to break the wealth/risk of death trade-off down into a number of conceptually manageable steps, thereby trying to attenuate the various biases that appear to be pervasive in responses to more direct contingent valuation questions in the health and safety field.     

Student Imagery of Practice in Social Work and Teacher Education: A Comparative Research Approach

Correspondence to Dr N. Gould, SSRADU, University of Bath, The New Church, Henry St, Bath BA1 1JR Summary Within the fields of adult and professional education, the lastten years have seen the development of the reflective learningparadigm. This refutes a technical-rational model of the relationshipbetween theory and practice, and proposes that practitionerknowledge is experientially constructed and organized throughthe schemata of imagery and metaphor. This paper outlines somefindings 6om a comparative research study of social work andteaching students which adopted a phenomenological approachto understanding the self-imagery of student practitioners andits relationship to prior experience. Some implications forsocial worker education are considered, including the conceptof ‘imaginization’—derived horn postmodernistorganizational theory—as a strategy for empowerment.     

PAYOFF LEVELS,LOSS AVOIDANCE,AND EQUILIBRIUM SELECTION IN GAMES WITH MULTIPLE EQUILIBRIA: AN EXPERIMENTAL STUDY

Game theorists typically assume that changing a game's payoff levels—by adding the same constant to, or subtracting it from, all payoffs—should not affect behavior. Although this invariance is an implication of the theory when payoffs mirror expected utilities, it is an empirical question when “payoffs” are actually money amounts. Loss avoidance is a phenomenon where payoff‐level changes matter when they change the signs of payoffs: gains become losses or vice versa. We report the results of a human‐subjects experiment designed to test for two types of loss avoidance: certain‐loss avoidance (avoiding a strategy leading to a sure loss, in favor of an alternative that might lead to a gain) and possible‐loss avoidance (avoiding a strategy leading to a possible loss, in favor of an alternative that leads to a sure gain). Subjects in the experiment play three versions of Stag Hunt, which are identical up to the level of payoffs, under a variety of treatments. We find strong evidence of behavior consistent with certain‐loss avoidance in the experiment. We also find evidence of possible‐loss avoidance, although weaker than that for certain‐loss avoidance. Our results carry implications for theorists modeling real‐life situations with game theory and for experimenters attempting to test theory and interpret observed behavior in terms of theory.

Leveraging symbolic capital: the use of blat networks across transnational spaces

In this article, we contribute to debates on how social networks sustain migrants' entrepreneurial activities. By reporting on 31 interviews with Eastern European migrants in the UK, we provide a critical lens on the tendency to assume that migrants have ready‐made social networks in the host country embedded in co‐ethnic communities. We extend this limited perspective by demonstrating how Eastern European migrants working in the UK transform blat social networks, formulated in the cultural and political contours of Soviet society, in their everyday lived experiences. Our findings highlight not only the monetarization of such networks but also the continuing embedded nature of trust existing within these networks, which cut across transnational spaces. We show how forms of social capital based on Russian language use and legacies of a shared Soviet past, are just as important as the role of ‘co‐ethnics’ and ‘co‐migrants’ in facilitating business development. In doing so, we present a more nuanced understanding of the role that symbolic capital plays in migrant entrepreneurial journeys and its multifaceted nature.     

On the Contingent Valuation of Safety and the Safety of Contingent Valuation: Part 1-Caveat Investigator

This article reports the results of two studies aimed at testing and refining a procedure for estimating willingness-to-pay based monetary values of safety using the contingent valuation method. In spite of the fact that respondents were given the opportunity to discuss various safety issues and key concepts in focus group meetings held in advance of individual interviews, and were also given ample opportunity to revise their responses in the light of the overall pattern of these responses, the results show clear evidence of extensive and persistent insensitivity to the scale and scope of the safety improvements that were specified in the contingent valuation questions, as well as vulnerability to framing effects. This clearly casts serious doubt on the reliability and validity of willingness-to-pay based monetary values of safety estimated using conventional contingent valuation procedures.
