Access can either be first-order or second-order. First order access concerns whether contents achieve representation in phenomenal consciousness at all; second-order access concerns whether phenomenally conscious contents are selected for metacognitive, higher order processing by reflective consciousness. When the optional and flexible nature of second-order access is kept in mind, there remain strong reasons to believe that exclusion failure can indeed isolate phenomenally conscious stimuli that are not so accessed. Irvine’s [Irvine, E. . Signal detection theory, the exclusion failure paradigm (...) and weak consciousness—Evidence for the access/phenomenal distinction? Consciousness and Cognition.] partial access argument fails because exclusion failure is indeed due to lack of second-order access, not insufficient phenomenally conscious information. Further, the enable account conforms with both qualitative differences and subjective report, and is simpler than the endow account. Finally, although first-order access may be a distinct and important process, second-order access arguably reflects the core meaning of access generally. (shrink)

Coalition announcement logic is one of the family of the logics of quantified announcements. It allows us to reason about what a coalition of agents can achieve by making announcements in the setting where the anti-coalition may have an announcement of their own to preclude the former from reaching its epistemic goals. In this paper, we describe a PSPACE-complete model checking algorithm for CAL that produces winning strategies for coalitions. The algorithm is implemented in a proof-of-concept model checker.

Van Lambalgen (1990) proposed a translation from a language containing a generalized quantifierQ into a first-order language enriched with a family of predicatesR i, for every arityi (or an infinitary predicateR) which takesQxg(x, y1,..., yn) to x(R(x, y1,..., y1) (x,y1,...,yn)) (y 1,...,yn are precisely the free variables ofQx). The logic ofQ (without ordinary quantifiers) corresponds therefore to the fragment of first-order logic which contains only specially restricted quantification. We prove that it is decidable using the method of analytic tableaux. Related (...) results were obtained by Andréka and Németi (1994) using the methods of algebraic logic. (shrink)

The generic ultrafilter${\cal G}_2 $forced by${\cal P}\left/\left$was recently proved to be neither maximum nor minimum in the Tukey order of ultrafilters, but it was left open where exactly in the Tukey order it lies. We prove${\cal G}_2 $that is in fact Tukey minimal over its projected Ramsey ultrafilter. Furthermore, we prove that for each${\cal G}_2 $, the collection of all nonprincipal ultrafilters Tukey reducible to the generic ultrafilter${\cal G}_k $forced by${\cal P}\left/{\rm{Fin}}^{ \otimes k} $forms a chain of lengthk. Essential to (...) the proof is the extraction of a dense subsetεkfrom +which we prove to be a topological Ramsey space. The spacesεk,k≥ 2, form a hierarchy of high dimensional Ellentuck spaces. New Ramsey-classification theorems for equivalence relations on fronts on εkare proved, extending the Pudlák–Rödl Theorem for fronts on the Ellentuck space, which are applied to find the Tukey and Rudin–Keisler structures below${\cal G}_k $.

A general method for constructing a new class of topological Ramsey spaces is presented. Members of such spaces are infinite sequences of products of Fraïssé classes of finite relational structures satisfying the Ramsey property. The Product Ramsey Theorem of Sokič is extended to equivalence relations for finite products of structures from Fraïssé classes of finite relational structures satisfying the Ramsey property and the Order-Prescribed Free Amalgamation Property. This is essential to proving Ramsey-classification theorems for equivalence relations on fronts, generalizing the (...) Pudlák–Rödl Theorem to this class of topological Ramsey spaces. To each topological Ramsey space in this framework corresponds an associated ultrafilter satisfying some weak partition property. By using the correct Fraïssé classes, we construct topological Ramsey spaces which are dense in the partial orders of Baumgartner and Taylor generating p-points which are k-arrow but not \-arrow, and in a partial order of Blass producing a diamond shape in the Rudin-Keisler structure of p-points. Any space in our framework in which blocks are products of n many structures produces ultrafilters with initial Tukey structure exactly the Boolean algebra \\). If the number of Fraïssé classes on each block grows without bound, then the Tukey types of the p-points below the space’s associated ultrafilter have the structure exactly \. In contrast, the set of isomorphism types of any product of finitely many Fraïssé classes of finite relational structures satisfying the Ramsey property and the OPFAP, partially ordered by embedding, is realized as the initial Rudin-Keisler structure of some p-point generated by a space constructed from our template.

Are the state’s obligations to victims of its own wrongdoing greater than to persons who have suffered from bad luck? Many people endorse an affirmative answer to this question. Call this the Difference View. This view can seem arbitrary from the perspective of the victims in question; why should a victim of bad luck, who is just as badly off through no fault of her own, be entitled to less assistance from the state than a victim of state-caused wrongful harm? (...) This paper defends a qualified version of the Difference View, the Threshold Version of the Difference View. According to this view, all disadvantaged persons, no matter what the cause of their disadvantage, must be compensated until they reach a minimum threshold of wellbeing; however, among disadvantaged persons above this threshold, full compensation is owed for those who are victims of state wrongdoing, whereas full compensation is not necessarily owed to those who are disadvantaged due to bad luck.

We build a collection of topological Ramsey spaces of trees giving rise to universal inverse limit structures, extending Zheng’s work for the profinite graph to the setting of Fraïssé classes of finite ordered binary relational structures with the Ramsey property. This work is based on the Halpern-Läuchli theorem, but different from the Milliken space of strong subtrees. Based on these topological Ramsey spaces and the work of Huber-Geschke-Kojman on inverse limits of finite ordered graphs, we prove that for each such (...) Fraïssé class, its universal inverse limit structure has finite big Ramsey degrees under finite Baire-measurable colorings. For such Fraïssé classes satisfying free amalgamation as well as finite ordered tournaments and finite partial orders with a linear extension, we characterize the exact big Ramsey degrees. (shrink)

Natasha McKeever argues that prima facie, a friends-with-benefits relationship can be, at the same time, a good friendship. This is because sex is compatible with friendship in that it can complement and potentially even strengthen the three core characteristics of friendship: mutual liking, mutual caring, and mutual sharing. She acknowledges that, by generating uncertainty and having the potential to generate feelings of romantic love, sex does pose risks to friendship. However, she argues that while these risks are significant considerations, (...) they can be mitigated and managed and so do not provide strong reasons against friends-with-benefits relationships.

England and Wales are moving toward a model of ‘opt out’ for use of personal confidential data in health research. Existing research does not make clear how acceptable this move is to the public. While people are typically supportive of health research, when asked to describe the ideal level of control there is a marked lack of consensus over the preferred model of consent. This study sought to investigate a relatively unexplored difference between the consent model that people prefer and (...) that which they are willing to accept. It also sought to explore any reasons for such acceptance. (shrink)

We define bisimulations for temporal logic with Since and Until. This new notion is compared to existing notions of bisimulations, and then used to develop the basic model theory of temporal logic with Since and Until. Our results concern both invariance and definability. We conclude with a brief discussion of the wider applicability of our ideas.

We investigate the effects of various forcings on several forms of the Halpern– Läuchli theorem. For inaccessible κ, we show they are preserved by forcings of size less than κ. Combining this with work of Zhang in [17] yields that the polarized partition relations associated with finite products of the κ-rationals are preserved by all forcings of size less than κ over models satisfying the Halpern– Läuchli theorem at κ. We also show that the Halpern–Läuchli theorem is preserved by <κ-closed (...) forcings assuming κ is measurable, following some observed reflection properties. (shrink)

Analogues of Ramsey’s Theorem for infinite structures such as the rationals or the Rado graph have been known for some time. In this context, one looks for optimal bounds, called degrees, for the number of colors in an isomorphic substructure rather than one color, as that is often impossible. Such theorems for Henson graphs however remained elusive, due to lack of techniques for handling forbidden cliques. Building on the author’s recent result for the triangle-free Henson graph, we prove that for (...) each [Formula: see text], the k-clique-free Henson graph has finite big Ramsey degrees, the appropriate analogue of Ramsey’s Theorem. We develop a method for coding copies of Henson graphs into a new class of trees, called strong coding trees, and prove Ramsey theorems for these trees which are applied to deduce finite big Ramsey degrees. The approach here provides a general methodology opening further study of big Ramsey degrees for ultrahomogeneous structures. The results have bearing on topological dynamics via work of Kechris, Pestov, and Todorcevic and of Zucker. (shrink)

Aversive autobiographical memories sometimes prompt maladaptive emotional responses and contribute to affective dysfunction in anxiety and depression. One way to regulate the impact of such memories is to create a downward counterfactual thought–a mental simulation of how the event could have been worse–to put what occurred in a more positive light. Despite its intuitive appeal, counterfactual thinking has not been systematically studied for its regulatory efficacy. In the current study, we compared the regulatory impact of downward counterfactual thinking, temporal distancing, (...) and memory rehearsal in 54 adult participants representing a spectrum of trait anxiety. Participants recalled regretful experiences and rated them on valence, arousal, regret, and episodic detail. Two to six days later, they created a downward counterfactual of the remembered event, thought of how they might feel about it 10 years from now, or simply rehearsed it. A day later, participants re-rated the phenomenological characteristics of the events. Across all participants, downward counterfactual thinking, temporal distancing, and memory rehearsal were equally effective at reducing negative affect associated with a memory. However, in individuals with higher trait anxiety, downward counterfactual thinking was more effective than rehearsal for reducing regret, and it was as effective as distancing in reducing arousal. We discuss these results in light of the functional theory of counterfactual thinking and suggest that they motivate further investigation into downward counterfactual thinking as a means to intentionally regulate emotional memories in affective disorders.

This paper investigates when it is possible for a partial ordering P to force Pκ(λ) \ V to be stationary in VP. It follows from a result of Gitik that whenever P adds a new real, then Pκ(λ) \ V is stationary in VP for each regular uncountable cardinal κ in VP and all cardinals λ > κ in VP [4]. However, a covering theorem of Magidor implies that when no new ω-sequences are added, large cardinals become necessary [7]. The (...) following is equiconsistent with a proper class of ω₁-Erdős cardinals: If P is N₁-Cohen forcing, then Pκ(λ) \ V is stationary in VP, for all regular κ ≥ N₂ and all λ > κ. The following is equiconsistent with an ω₁-Erdős cardinal: If P is N₁-Cohen forcing, then PN₂ (N₃) \ V is stationary in VP. The following is equiconsistent with κ measurable cardinals: If P is κ-Cohen forcing, then Pκ + (Nκ \ V is stationary in VP. (shrink)

A Turing degree a is said to be almost everywhere dominating if, for almost all $X \in 2^{\omega}$ with respect to the "fair coin" probability measure on $2^{\omega}$ , and for all g: $\omega \rightarrow \omega$ Turing reducible to X, there exists f: $\omega \rightarrow \omega$ of Turing degree a which dominates g. We study the problem of characterizing the almost everywhere dominating Turing degrees and other, similarly defined classes of Turing degrees. We relate this problem to some questions in (...) the reverse mathematics of measure theory. (shrink)

This paper describes how to ethically conduct research with Black populations at the intersection of COVID-19 and the Black Lives Matter movement. We highlight the issues of historical mistrust in the USA and how this may impact Black populations’ participation in COVID-19 vaccination trials. We provide recommendations for researchers to ethically engage Black populations in research considering the current context. Our recommendations include understanding the impact of ongoing trauma, acknowledging historical context, ensuring diverse research teams and engaging in open and (...) honest conversations with Black populations to better address their needs. The core of our recommendation is recognising the impact of trauma in our research and health care practices. (shrink)

In a review of the cell biology and heredity studies of 1900–1910, Bernardino Fantini argues that the choice of an experimental subject or organism was crucial in opening up new discoveries and new theories for specific fields of research.69 Thinking on a broader level, Bütschli expressed a similar view when he stated that an understanding of the true nature and structure of the “elementary organism” was crucial to the whole of biology. In this article we have traced the impact of (...) Bütschli's unicellular model of protozoa up to the general acceptance of the eukaryotic cell as nature's primary organism. We have also seen that Bütschli's vision in the Studien gave birth to Protistenforschung and Zellforschung, sister sciences whose task it was to further and integrate knowledge of the living cell. Of necessity, we have confined ourselves to German scientific developments. However, our attempt to recapture and define the unity and meaning of a biology of the “cell-microcosm” has given us pause to reconsider the development and nature of Wilhelmian biological science.

The text defines the fundamental terms relevant to the process of sampling, elaborates the characteristics of individual samples, selection strategies, and the key methodological issues and dilemmas of the researchers during the procedures of sampling. The selection of a sample is an essential aspect when planning the methodology of empirical research and has a key role in ensuring the reliability and validity of research results. Researchers should carefully consider the characteristics of the population and the specific research objectives and accordingly (...) choose the sampling strategy. Representative samples minimize bias and provide a higher level of confidence when generalizing results to a larger population. Non-representative samples are valuable when the selection of a representative sample is impractical or impossible. They involve different forms of bias but offer flexibility, cost-effectiveness and practicality. Non-representative samples are applicable in qualitative studies and in the research with populations that are hard to reach. However, it is important to be aware of their limitations and the justification for generalization findings outside the specific sample. Regardless of the used strategy, researchers must strive for transparency, clearly documenting the unit selection procedure and stress the potential limitations as key elements to ensure the reliability and validity of the research results.

We present a framework for verifying systems composed of heterogeneous reasoning agents, in which each agent may have differing knowledge and inferential capabilities, and where the resources each agent is prepared to commit to a goal (time, memory and communication bandwidth) are bounded. The framework allows us to investigate, for example, whether a goal can be achieved if a particular agent, perhaps possessing key information or inferential capabilities, is unable (or unwilling) to contribute more than a given portion of its (...) available computational resources or bandwidth to the problem. We present a novel temporal epistemic logic, BMCL-CTL , which allows us to describe a set of reasoning agents with bounds on time, memory and the number of messages they can exchange. The bounds on memory and communication are expressed as axioms in the logic. As an example, we show how to axiomatise a system of agents which reason using resolution and prove that the resulting logic is sound and complete. We then show how to encode a simple system of reasoning agents specified in BMCL-CTL in the description language of the Mocha model checker (Alur et al., Proceedings of the tenth international conference on computer-aided verification (CAV) , 1998), and verify that the agents can achieve a goal only if they are prepared to commit certain time, memory and communication resources.

Relative to a hyperstrong cardinal, it is consistent that measure one covering fails relative to HOD. In fact it is consistent that there is a superstrong cardinal and for every regular cardinal κ, κ + is greater than κ + of HOD. The proof uses a very general lemma showing that homogeneity is preserved through certain reverse Easton iterations.

Refugees and asylum seekers may experience challenges related to pre-arrival experiences, structural disadvantage after migration and during resettlement requiring the need for special protection when participating in research. The aim was to review if and how people with refugee and asylum seeker backgrounds have had their need for special protection addressed in national and international research ethics guidelines. A systematic search of grey literature was undertaken. The search yielded 2187 documents of which fourteen met the inclusion criteria. Few guidelines addressed (...) specific ethical considerations for vulnerable groups much less people with refugee and asylum seeker backgrounds. One guideline explicitly addressed vulnerability for refugees and asylums seekers. To ensure members of ethics committees and researchers consider the potential challenges of conducting research with these groups, guidelines may need to be supplemented with a refugee and asylum seeker specific research ethics framework. Such a framework may be necessary to optimally protect people with refugee and asylum seeker backgrounds in research. (shrink)

We consider two systems of constructive modal logic which are computationally motivated. Their modalities admit several computational interpretations and are used to capture intensional features such as notions of computation, constraints, concurrency, etc. Both systems have so far been studied mainly from type-theoretic and category-theoretic perspectives, but Kripke models for similar systems were studied independently. Here we bring these threads together and prove duality results which show how to relate Kripke models to algebraic models and these in turn to the (...) appropriate categorical models for these logics.

Scientific and medical contraceptive standards are commonly believed to have begun with the advent of the oral contraceptive pill in the late 1950s. This article explains that in Britain contraceptive standards were imagined and implemented at least two decades earlier by the Family Planning Association, which sought to legitimize contraceptive methods, practice and provision through the foundation of the field of contraceptive science. This article charts the origins of the field, investigating the three methods the association devised and employed to (...) achieve its goal of effecting contraceptive regulation. This was through the development of standardized methods to assess spermicidal efficacy; the establishment of quality, strength and manufacturing standards for rubber prophylactics; and the institution of animal trials to ensure the safety of specific contraceptives. The association publicized the results of its scientific testing on proprietary contraceptives in its annual Approved List of contraceptives. This provided doctors and chemists with a definitive register of safe and effective methods to prescribe. (shrink)

The Higher School Certificate is a certificate that recognises the successful completion of secondary education in New South Wales, Australia.

One of the principles of CRPDis “respect for inherent dignity, individual autonomy including the freedom to makeone’s own choices and independence”, whereby persons with disabilities are recognizedas holders of rights taking into account their specific situation. CRPD recognizes inArticle 6 that “women and girls with disabilities are subject to multiple discrimination”and (...) mandates signatory countries to “take measures to ensure their full and equalenjoyment of all human rights and fundamental freedoms.” The research was done inorder to examine the readiness of the state to institutionally cover the awareness of girlsand women with disabilities, their education on the issue of violence, access to servicesand information appropriate to the needs of each category separately, as well as systemicsolutions for their protection from violence. A qualitative research strategy was applied,and the research was conducted with representatives of the Centers for Social Work, representativesfrom the Ministry of Labor and Social Policy, professionals who are directproviders of services in the field of non-family protection, as well as the girls and womenwith disabilities themselves. The main conclusions that emerge from the research saythat girls and women with disabilities are more susceptible to violence, especially bytheir partners or family members. More awareness is needed to recognize and encouragereporting of violence. (shrink)

Gender differences in children’s and adults’ time use are well documented, but few have examined the intervening period—young adulthood. Because many Americans navigate higher education in young adulthood, college time use provides insight into how gendered behaviors evolve during this critical life stage. Using three years of time use data from the National Longitudinal Survey of Freshmen and latent transition analysis, I examine gender differences in time use within and across the college years for those in selective institutions. Among students (...) whose time use is consistent throughout college, I find that women exhibit academically-oriented time use more often, and men exhibit socially oriented time use more often. However, many men transition from social time use at the beginning of college to academic time use toward the end—to the extent that gender gaps in academic time use converge by the third year. I argue that men and women construct distinct college pathways, and that men, in particular, must reroute their time use to accommodate gendered expectations for the transition to adulthood.

There exists a considerable body of work on epistemic logics for resource-bounded reasoners. In this paper, we concentrate on a less studied aspect of resource-bounded reasoning, namely, on the ascription of beliefs and inference rules by the agents to each other. We present a formal model of a system of bounded reasoners which reason about each other’s beliefs, and investigate the problem of belief ascription in a resource-bounded setting. We show that for agents whose computational resources and memory are bounded, (...) correct ascription of beliefs cannot be guaranteed, even in the limit. We propose a solution to the problem of correct belief ascription for feasible agents which involves ascribing reasoning strategies , or preferences on formulas, to other agents, and show that if a resource-bounded agent knows the reasoning strategy of another agent, then its ascription of beliefs to the other agent is correct in the limit.

The universal homogeneous triangle-free graph, constructed by Henson [A family of countable homogeneous graphs, Pacific J. Math.38(1) (1971) 69–83] and denoted H3, is the triangle-free analogue of the Rado graph. While the Ramsey theory of the Rado graph has been completely established, beginning with Erdős–Hajnal–Posá [Strong embeddings of graphs into coloured graphs, in Infinite and Finite Sets. Vol.I, eds. A. Hajnal, R. Rado and V.

Komjáth and V. Rödl, Coloring of universal graphs, Graphs Combin.2(1) (1986) 55–60] and edge colorings [N. Sauer, Edge partitions of the countable triangle free homogenous graph, Discrete Math.185(1–3) (1998) 137–181]. This was due to a lack of broadscale techniques. We solve this problem in general: For each finite triangle-free graph G, there is a finite number T(G) such that for any coloring of all copies of G in H3 into finitely many colors, there is a subgraph of H3 which is again universal homogeneous triangle-free in which the coloring takes no more than T(G) colors. This is the first such result for a homogeneous structure omitting copies of some nontrivial finite structure. The proof entails developments of new broadscale techniques, including a flexible method for constructing trees which code H3 and the development of their Ramsey theory. (shrink)

The definition of consumerism is multifaceted, extending from the consumption of goods and services to its more negative connotations: the obsessive consumption of goods, exploitation of the people who create them and greed.

How has the nature of how we create and consume (...) goods evolved and how is this linked to moral responsibility and autonomy?

Colleges and universities exist within a political arena where external demands for accountability materialize within a market-driven environment. As a result, government agencies pressure colleges and universities to rely on assessment and transparent reporting to become more market-driven assuming that the competition within the market, led by public choice and institutional selection, will drive improvements in learning and will also self-govern the institutions.
