The movement for the Unity of Science has been making headway for a number of years, and each year more workers in the various scientific domains have expressed their interest in it by participating in the discussion of its aims and its specific problems. A characteristic feature of this movement which explains this growing interest is that it does not propose a “super-science” which is to legislate to the special sciences. Its proposal of a Unity of Science is of a (...) different kind, not based upon some grand metaphysical view of any sort. Those who are active within this movement are emphatic in their insistence that instead of aiming at a synthesis of the different sciences on the basis of a prior and independent philosophy, the special sciences will themselves supply their own synthesizing glue. For appreciating the significance of this movement it is therefore necessary to keep in mind that its tendency is toward a unified science, departmentalized into special sciences, and not toward an artificial and speculative juxtaposition of an autonomous philosophy and an autonomous group of sciences.

2 Enoch 58–59 provides an esoteric and somewhat eccentric delineation of attitudes toward the mistreatment of animals within some sect of Egyptian Judaism, in all probability. Three attitudes, having to do with the mistreatment of animals in failing to feed them properly, the wrongful binding of animals for sacrifice, and possible secret sexual exploitation of animals, are delineated along with warnings regarding the effects of such treatment on the human soul at the great judgment. This linking of how humans treat (...) animals with how humans will be judged in “the great age” is unique in the literature of this period and demonstrates a deep concern for animal welfare that has been largely dormant in many facets of religion until more recent times.

Much research has been done on the economic effects of self-employment, environmental conditions for entrepreneurial success, as well as attributes if the person him-/herself fits to this career path. To successfully run a business, however, is contingent on the health of the entrepreneur. In particular, small business owners (being solo self-employed without personnel) face financial uncertainties, a high workload, long working hours, and are often unable to call in sick. This study aimed at exploring the working situation considering resources (e.g., (...) autonomy), strain (e.g., dependency on contracts with clients) and health and career outcomes of small business owners. This study used a qualitative approach to comprehensively mirror the working situation. Participants who were 29 small business owners from Germany gave permission for recording expert interviews in which they reported, for example, on health complaints, recovery opportunities, obstacles and resources while running their businesses. The interviews emphasize the meaning of active actions and own responsibility for creating working conditions and enabling autonomy. Small business owners yet have to be able to use the autonomy. Besides personal preferences regarding the career path as being pulled into self-employment and not pushed by situational circumstances also marketability and flexibility played a role and explained health and career issues. Our findings underline that the social network is of utmost importance to small business owners and that social support – even or despite of being solo self-employed – is a key to sustaining health and satisfaction. As voluntariness played an essential role for selecting this specific career path those being pulled into self-employment as no other jobs are available should receive particular support through career counseling. One shortcoming of prior research is that the concrete working situation of small business owners and its impact on health and career has not adequately been taken into account. Based on work-related stress models we developed a frame model specific for the situation of small business owners which allows concrete hypotheses for further quantitative research. (shrink)

We study the expressive power in the finite of the logic Fixed-Point+Counting, the extension of first-order logic which is obtained through adding both the fixed-point constructor and the ability to count. To this end an isomorphism preserving (`generic') model of computation is introduced whose PTime restriction exactly corresponds to this level of expressive power, while its PSpace restriction corresponds to While+Counting. From this model we obtain a normal form which shows a rather clear separation of the relational vs. the arithmetical (...) side of the algorithms involved. In parallel, we study the relations of Fixed-Point+Counting with the infinitary logics L r ∞ω (∃ ≥ m ) m∈ω and the corresponding pebble games. The main result, however, involves the concept of an arithmetical invariant. By this we mean a functor taking every finite relational structure to an expansion of (an initial segment of) the standard arithmetical structure. In particular its values are linearly ordered structures. We establish the existence of a family of arithmetical invariants (J r ) r≥ 1 with the following properties: $\bullet$ The invariants themselves can be evaluated in polynomial time. $\bullet$ A class of finite relational structures is definable in Fixed-Point+Counting if and only if membership can be decided in polynomial time on the basis of the values of one of the invariants. $\bullet$ The invariant J r classifies all finite relational structures exactly up to equivalence with respect to the logic L r ∞ω (∃ ≥ m ) m∈ω . We also give a characterization of Fixed-Point+Counting in terms of sequences of formulae in the L r ωω (∃ ≥ m ) m∈ω : It corresponds exactly to the polynomial time computable families (φ n ) n∈ω in these logics. Towards a positive assessment of the expressive power of Fixed-Point+Counting, it is shown that the natural extension of fixed-point logic by Lindström quantifiers, which capture all the PTime computable properties of cardinalities of definable predicates, is strictly weaker than what we get here. This implies in particular that every extension of fixed-point logic by means of monadic Lindstrom quantifiers, which stays within PTime, must be strictly contained in Fixed-Point+Counting. (shrink)

Lyndon's Interpolation Theorem asserts that for any valid implication between two purely relational sentences of first-order logic, there is an interpolant in which each relation symbol appears positively (negatively) only if it appears positively (negatively) in both the antecedent and the succedent of the given implication. We prove a similar, more general interpolation result with the additional requirement that, for some fixed tuple U of unary predicates U, all formulae under consideration have all quantifiers explicitly relativised to one of the (...) U. Under this stipulation, existential (universal) quantification over U contributes a positive (negative) occurrence of U. It is shown how this single new interpolation theorem, obtained by a canonical and rather elementary model theoretic proof, unifies a number of related results: the classical characterisation theorems concerning extensions (substructures) with those concerning monotonicity, as well as a many-sorted interpolation theorem focusing on positive vs. negative occurrences of predicates and on existentially vs. universally quantified sorts.

Journal Name: Apeiron Issue: Ahead of print.

An “insightful” and in-depth look at anti-science politics and its deadly results (Maria Konnikova, New York Times–bestselling author of The Biggest Bluff). Thomas Jefferson said, “Wherever the people are well informed, they can be trusted with their own government.” But what happens when they aren’t? From climate change to vaccinations, transportation to technology, health care to defense, we are in the midst of an unprecedented expansion of scientific progress—and a simultaneous expansion of danger. At the very time we need them (...) most, scientists and the very idea of objective knowledge are being bombarded by a vast, well-funded war on science, and the results are deadly. Whether it’s driven by identity politics, ideology, or industry, the result is an unprecedented erosion of thought in Western democracies as voters, policymakers, and justices actively ignore scientific evidence, leaving major policy decisions to be based more on the demands of the most strident voices. This compelling book investigates the historical, social, philosophical, political, and emotional reasons why evidence-based politics are in decline and authoritarian politics are once again on the rise on both left and right—and provides some compelling solutions to bring us to our collective senses, before it's too late. “If you care about attacks on climate science and the rise of authoritarianism, if you care about biased media coverage and shake-your-head political tomfoolery, this book is for you.”—The Guardian.

In this paper we investigate the logical consequences of the common understanding of amateurism in the context of big-time US college athletics, and in so doing, illustrate a method based on linguistic analysis and logic. The initial thrust of the paper centres on the term ?amateur? as presupposed by the late Professor Brand in his attempt to justify the ?business? of NCAA-sponsored Division I sports by decoupling the ?participants from the enterprise?. Next, we examine a more rigorous definition of the (...) term ?amateur? in order to show more clearly the difficulties posed by the current situation in college athletics. Additionally, our use of linguistic analysis exposes a flaw in the NCAA's recent move to amend by-law 12.02 in an attempt to avoid the charge of exploitation. Lastly, we put forth a new proposal for better dealing with the central issues swirling around the NCAA as it strives to formulate sound policy at this ?tectonic? juncture of players, fans, college programmes and academic integrity.
