    Charney's target article continues a critique of genetic blueprint models of development that suggests reconsideration of concepts of adaptation, inheritance, and environment, which can be well illustrated in current research on infant attachment. The concepts of development and adaptation are so heavily based on the model of genetics and inheritance forged in the modern synthesis that they will require reconsideration to accommodate epigenetic inheritance.

    We study the Medvedev degrees of mass problems with distinguished topological properties, such as denseness, closedness, or discreteness. We investigate the sublattices generated by these degrees; the prime ideal generated by the dense degrees and its complement, a prime filter; the filter generated by the nonzero closed degrees and the filter generated by the nonzero discrete degrees. We give a complete picture of the relationships of inclusion holding between these sublattices, these filters, and this ideal. We show that the sublattice (...)

    We prove a number of results in effective randomness, using methods in which $\Pi _{1}^{0}$ classes play an essential role. The results proved include the fact that every PA Turing degree is the join of two random Turing degrees, and the existence of a minimal pair of LR degrees below the LR degree of the halting problem.

    Sustainable investment (SI), which integrates social, environmental and ethical issues, has grown from a niche market of individual ethical investors to embrace institutional investors (e.g. pension funds) resulting in £764 billion in assets under management in the UK alone [Eurosif, 2008 : ‘European SRI Study 2008’ (Eurosif, Paris)]. Explaining this growth is complex, involving shifts in personal and collective values, reactions to corporate scandals, scientific and media pronouncements about climate change, Government initiatives, responses from financial markets and the influence of (...)

    Del Giudice provides an extension of the life history theory of attachment that incorporates emerging data suggestive of sex differences in avoidant male and preoccupied female attachment patterns emerging in middle childhood. This commentary considers the place of disorganized attachment within this theory and why male children may be more prone to disorganized attachment by drawing on Trivers's parental investment theory.

    We say that A ≤LR B if every B-random number is A-random. Intuitively this means that if oracle A can identify some patterns on some real γ. In other words. B is at least as good as A for this purpose. We study the structure of the LR degrees globally and locally (i.e., restricted to the computably enumberable degrees) and their relationship with the Turing degrees. Among other results we show that whenever α in not GL₂ the LR degree of (...)

    For more than 15 years, the investment community and the academic community have written extensively on socially responsible investment (SRI). Despite the abundance of SRI thought, the adoption of SRI practices among institutional investors is a comparative rarity. This paper endeavours to achieve two goals. First, by integrating the practitioner and academic literature on the topic, the paper attempts to identify the many impediments to SRI in Europe from an institutional investor's perspective. Second, the paper proposes a unitary framework to (...)

    The strong weak truth table (sw) reducibility was suggested by Downey, Hirschfeldt, and LaForte as a measure of relative randomness, alternative to the Solovay reducibility. It also occurs naturally in proofs in classical computability theory as well as in the recent work of Soare, Nabutovsky, and Weinberger on applications of computability to differential geometry. We study the sw-degrees of c.e. reals and construct a c.e. real which has no random c.e. real (i.e., Ω number) sw-above it.

    We show that in the c.e. weak truth table degrees if b < c then there is an a which contains no hypersimple set and b < a < c. We also show that for every w < c in the c.e. wtt degrees such that w is hypersimple, there is a hypersimple a such that w < a < c. On the other hand, we know that there are intervals which contain no hypersimple set.

    Hermann Grassmann's Ausdehnungslehre of 1844 and his Lehrbuch der Arithmetik of 1861 are landmark works in mathematics; the former not only developed new mathematical fields but also both contributed to the setting of modern standards of rigor. Their very modernity, however, may obscure features of Grassmann's view of the foundations of mathematics that were not adopted since. Grassmann gave a key role to the learning of mathematics that affected his method of presentation, including his emphasis on making initial assumptions explicit. (...)

    In this article I argue that despite the claims of some, all whites in racialized societies "have race." But because of the current context of race in our society, I argue that scholars of "whiteness" face several difficult theoretical and methodological challenges. First is the problem of how to avoid essentializing race when talking about whites as a social collective. That is, scholars must contend with the challenge of how to write about what is shared by those racialized as white (...)

    The infinite time Turing machine analogue of Post's problem, the question whether there are semi-decidable supertask degrees between 0 and the supertask jump 0∇, has in a sense both positive and negative solutions. Namely, in the context of the reals there are no degrees between 0 and 0∇, but in the context of sets of reals, there are; indeed, there are incomparable semi-decidable supertask degrees. Both arguments employ a kind of transfinite-injury construction which generalizes canonically to oracles.

    An important goal of ethical investment is to influence companies to improve their ethical and environmental performance. The principal means that many ethical funds employ is passive market signalling, which may not, on its own, have a significant effect. A much more promising approach may be active engagement. This paper reports on a questionnaire study of a sample of 1146 ethical investors in order to assess whether U.K. ethical investors would support more activist ethical investment and whether they would be (...)
