The class \ of t rue p airing a lgebras is defined to be the class of relation algebras expanded with concrete set theoretical projection functions. The main results of the present paper is that neither the equational theory of \ nor the first order theory of \ are decidable. Moreover, we show that the set of all equations valid in \ is exactly on the \ level. We consider the class \ of the relation algebra reducts of \ ’s, (...) as well. We prove that the equational theory of \ is much simpler, namely, it is recursively enumerable. We also give motivation for our results and some connections to related work. (shrink)

The honesty of animal communication is in the spot lights in the last 30 years. During most of this time the field was dominated by one explanation: Zahavi’s handicap principle (Zahavi, J Theor Biol 67:603–605, 1975 ; Grafen, J Theor Biol 144:517–546, 1990 ). Grose (Biol Philos 2011 ) embarks to explain both the success of the theory and the empirical difficulties that exist despite this success. While I wholeheartedly agree with the criticism offered by Grose and with almost all (...) the claims he makes, the treatment of the issue is far from complete and it still leaves much to be explained. Accordingly, my commentary consist of six sections: in the first section I clear up some technical issues left unexposed, most importantly the role of strategic cost in handicap signalling; in the second section I relate this to empirical testing; in the next section I comment on the historical development of the handicap principle; in the fourth section I review the biological models that came up with conclusions that contradict the handicap principle; in the fifth section I discuss the reasons behind the success of the handicap theory; finally, in the last section I discuss the application of the handicap theory to anthropology and human sciences.

We show that the equational theory of representable lower semilattice-ordered residuated semigroups is finitely based. We survey related results.

We wish to give a precise formulation of the intuitive concept: The degree to which the known facts support a given hypothesis.

In the past decades, research has raised the idea of a theology of the Septuagint on various occasions. Important works were recently published on this topic in the Handbuch zur Septuaginta and the Septuagint and Cognate Studies series. The general theological tendencies of the LXX are identified by scholars in eschatology, messianism, anti-anthropomorphism and angelology. These tend to all be regarded as further developments of the theology of the Hebrew Bible. However, one can trace the evolution of these and other (...) main topics of the LXX in the New Testament and in the later apostolic writings as well. Based on three concise case studies, I point out the evolution of theological ideas from the HB through the LXX up to the NT in this paper. First, I will discuss the importance of the 'Name of God'-theology which is increasingly present in the LXX and has a key role in the messianic passages of the NT. Then in two points it will be argued that addressing Jesus as κύριος implies theological accents which can be detected in the LXX. These observations aim to show that the development of the religious ideologies of the HB can be followed not only in the LXX but in the NT and beyond as well. The importance of a theology of the LXX goes beyond the HB research, having significant implications for the NT as well. In fact, such theology could build the bridge between the HB and the NT, and should not only be written from the viewpoint of the HB but also considering the NT. CONTRIBUTION: This contribution traces the routes of three theological concepts originating in the Hebrew Bible developed further in the LXX and finally adopted by the New Testament. Based on these three examples, it is suggested here as a novel idea that a theology of the LXX should not be written only with the Hebrew Bible in mind but also considering the New Testament.

Glossolalia (“speaking in tongues”) is a rhythmic utterance of word‐like strings of sounds, regularly occurring in religious mass gatherings or various forms of private religious practices (e.g., prayer and meditation). Although specific verbal learning capacities may characterize glossolalists, empirical evidence is lacking. We administered three statistical learning tasks (artificial grammar, phoneme sequence, and visual‐response sequence) to 30 glossolalists and 30 matched control volunteers. In artificial grammar, participants decide whether pseudowords and sentences follow previously acquired implicit rules or not. In sequence (...) learning, they gradually draw out rules from repeating regularities in sequences of speech sounds or motor responses. Results revealed enhanced artificial grammar and phoneme sequence learning performances in glossolalists compared to control volunteers. There were significant positive correlations between daily glossolalia activity and artificial grammar learning. These results indicate that glossolalists exhibit enhanced abilities to extract the statistical regularities of verbal information, which may be related to their unusual language abilities. (shrink)

We look at lower semilattice-ordered residuated semigroups and, in particular, the representable ones, i.e., those that are isomorphic to algebras of binary relations. We will evaluate expressions in representable algebras and give finite axiomatizations for several notions of validity. These results will be applied in the context of substructural logics.

Human language and human music are both unique communication systems that evolved in the human lineage. Here, I propose that they share the same root, they evolved from an ancestral communication system yet to be described in detail. I suggest that pre-hunt charade was this shared root, which helped organize and coordinate the hunt of early hominins.

In this paper we define computationally well-behaved versions of classical first-order logic and prove that the validity problem is decidable.

We show that the equational theory of representable lattice-ordered residuated semigroups is not finitely axiomatizable. We apply this result to the problem of completeness of substructural logics.

The origin of human language is one of the most fascinating and most difficult problems of evolution. Here I argue that pre-hunt communication was the starting context of the evolution of human language. Hunting of big game created a shared interest; animals and hunting actions are easy to imitate; the need to plan created a pressure for increasing complexity; and finally, cultural inheritance of hunting tools and know-how made the transition unique. I further argue that this “first step” was actually (...) a two-stage process where first indexical and iconic signs evolved to coordinate recruitment for the hunt; then later, in the second stage, the complexity of this communication system increased as a response to the increased demand to coordinate group-hunting effort (including division of labor). I provide a review of the fossil record and show that the available evidence is fully compatible with the theory. (shrink)

Weather imagery plays a major role in Hosea. Hosea 2 recalls the image of an unfaithful wife; Hosea 4:2-3 describes the withering of the land; in 6:3; 10:12; 14:6, the several types of precipitation draw attention to the utterance of YHWH or the requested righteousness; in 9:10.13.16; 10:1; 13:5; 14:6.8, Israel is symbolised by different plants that blossom and wither, depending on their relation to Yhwh. In all of these instances, weather phenomena contribute to these images. In this article, I (...) try to catalogue and evaluate the metaphors and concepts to look at how meteorological images convey theological and historical messages, and vice versa how historical events or sociological procedures demonstrate their consequences in nature, especially in the weather. It seems that weather imagery is used to describe the consequences of idolatry, injustice and false politics. These cause drought and famine in a concrete sense, but the withering of Israel figuratively, the last word of the book is a call for repentance that could ensure Israel's well-being once again. With these metaphors, Hosea explicitly delivers a plea for monolatry and righteousness, as well as for equality, in an implicit way. These pieces of evidence can provide a basis for further interpretation from the hermeneutical perspective of the notion called 'interconnectedness'. CONTRIBUTION: This article analyses the weather imagery of the Book of Hosea and contributes to a better understanding of the use of these metaphors in prophetic discourses. (shrink)

Although the work consists of sixteen connected chapters, there is a difference of motivation that led to the book being published in two volumes. The first eleven chapters, comprising Volume I, attempt to teach good guessing through examples. The remaining chapters, in Volume II, deal with general principles of plausible reasoning.

In this paper we show that relativized versions of relation set algebras and cylindric set algebras have undecidable equational theories if we include coordinatewise versions of the counting operations into the similarity type. We apply these results to the guarded fragment of first-order logic.

In 1948 Hempel and Oppenheim proposed an explicatum for the concept of systematic power 1, pp. 164–167. Since that time some shortcomings have been found in this first attempt. It is the purpose of this paper to show that one can keep the basic approach of the ‘48 paper, and overcome the known disadvantages by means of changes in the details of the definition. In this improvement certain tools will be used that were not available in 1948.

Traces of thoughts. The place of a theology of the Septuagint in biblical scholarship: In the past decades, research has raised the idea of a theology of the Septuagint (LXX) on various occasions. Important works were recently published on this topic in the Handbuch zur Septuaginta and the Septuagint and Cognate Studies series. The general theological tendencies of the LXX are identified by scholars in eschatology, messianism, anti-anthropomorphism and angelology. These tend to all be regarded as further developments of the (...) theology of the Hebrew Bible (HB). However, one can trace the evolution of these and other main topics of the LXX in the New Testament (NT) and in the later apostolic writings as well. Based on three concise case studies, I point out the evolution of theological ideas from the HB through the LXX up to the NT in this paper. First, I will discuss the importance of the ‘Name of God’-theology which is increasingly present in the LXX and has a key role in the messianic passages of the NT. Then in two points it will be argued that addressing Jesus as κύριος implies theological accents which can be detected in the LXX. These observations aim to show that the development of the religious ideologies of the HB can be followed not only in the LXX but in the NT and beyond as well. The importance of a theology of the LXX goes beyond the HB research, having significant implications for the NT as well. In fact, such theology could build the bridge between the HB and the NT, and should not only be written from the viewpoint of the HB but also considering the NT.

In this commentary I argue that the notion of incommensurability can be extended to the child's developing theories of mind. I use Carey's concept of Quinian bootstrapping and show that this learning process can account for the acquisition of the semantics of mental terms. I suggest a distinction among three stages of acquisition and adopt the theory–theory of conceptual development.

An increasing number of Muslim asylum seekers and refugees convert to Christianity in Europe. The conversion motifs in these individuals are unknown. In this study, we applied biographical interviews in 124 converts. There were two dominant patterns: intellectual —intellectual plus experimental motifs, and mystical —mystical plus affectional motifs. Pure experimental and affectional motifs were rare, and there were no revivalist and coercive motifs. Demographic parameters did not predict conversion motifs. We found no evidence for social pressure. These results indicate that (...) finding meaning and consolation in Christian religious teachings and mystical experiences with a high emotional content are the two leading religious conversion motifs.

The acquisition of complex motor, cognitive, and social skills, like playing a musical instrument or mastering sports or a language, is generally associated with implicit skill learning . Although it is a general view that SL is most effective in childhood, and such skills are best acquired if learning starts early, this idea has rarely been tested by systematic empirical studies on the developmental pathways of SL from childhood to old age. In this paper, we challenge the view that childhood (...) and early school years are the prime time for skill learning by tracking age-related changes in performance in three different paradigms of SL. We collected data from participants between 7 and 87 years for a Serial Reaction Time Task testing the learning of motor sequences, an Artificial Grammar Learning task testing the extraction of regularities from auditory sequences, and Probabilistic Category Learning in the Weather Prediction task , a non-sequential categorization task. Results on all three tasks show that adolescence and adulthood are the most efficient periods for skill learning, since instead of becoming less and less effective with age, SL improves from childhood into adulthood and then later declines with aging.
