Listenmee® and Listenmee® smartphone application: Synchronizing walking to rhythmic auditory cues to improve gait in Parkinson’s disease

Evidence supports the use of rhythmic external auditory signals to improve gait in PD patients (Arias & Cudeiro, 2008; Kenyon & Thaut, 2000; McIntosh, Rice & Thaut, 1994; McIntosh et al., 1997; Morris, Iansek, & Matyas, 1994; Thaut, McIntosh, & Rice, 1997; Suteerawattananon, Morris, Etnyre, Jankovic, & Protas , 2004; Willems, Nieuwboer, Chavert, & Desloovere, 2006). However, few prototypes are available for daily use, and to our knowledge, none utilize a smartphone application allowing individualized sounds and cadence. Therefore, we analyzed the effects on gait of Listenmee®, an intelligent glasses system with a portable auditory device, and present its smartphone application, the Listenmee app®, offering over 100 different sounds and an adjustable metronome to individualize the cueing rate as well as its smartwatch with accelerometer to detect magnitude and direction of the proper acceleration, track calorie count, sleep patterns, steps count and daily distances. The present study included patients with idiopathic PD presented gait disturbances including freezing. Auditory rhythmic cues were delivered through Listenmee®. Performance was analyzed in a motion and gait analysis laboratory. The results revealed significant improvements in gait performance over three major dependent variables: walking speed in 38.1%, cadence in 28.1% and stride length in 44.5%. Our findings suggest that auditory cueing through Listenmee® may significantly enhance gait performance. Further studies are needed to elucidate the potential role and maximize the benefits of these portable devices.     

Textbook Buddhism: introductory books on the Buddhist religion

Textbooks on Buddhism comprise a large, varied genre and have long been used to introduce the religion to students in academic settings. This review essay examines ten textbooks on the subject, noting their distinctive features, strengths, and weaknesses, as well as the types of courses that are well suited to each work. Additional information from a survey on Buddhism textbooks conducted by the author is used to supplement our understanding of which sources are regularly used in Buddhism courses and why. Unresolved tensions over whether to stress the coherence or diversity of Buddhism, and how comprehensive a textbook should be, are noted. Arguing that ‘Textbook Buddhism,' as a product of scholarly imagination, is a distinctive form of the tradition, it behooves specialists to be more reflective about their use of textbooks and to be more intentional in helping students to read them critically.     

Textbooks for teaching the anthropology of religion: a review

Written from the perspective of those who teach the anthropology of religion, the paper reviews a selection of texts commonly used in teaching. The authors find the texts are generally useful, although those written clearly and with good cross-referencing detail (index, bibliography, overviews) are the most helpful. One major finding is the range of views over what might constitute 'textbook’ - itself a fairly contested term more widely.     

When to (or not to) trust intelligent machines: Insights from an evolutionary game theory analysis of trust in repeated games

The actions of intelligent agents, such as chatbots, recommender systems, and virtual assistants are typically not fully transparent to the user. Consequently, users take the risk that such agents act in ways opposed to the users’ preferences or goals. It is often argued that people use trust as a cognitive shortcut to reduce the complexity of such interactions. Here we formalise this by using the methods of evolutionary game theory to study the viability of trust-based strategies in repeated games. These are reciprocal strategies that cooperate as long as the other player is observed to be cooperating. Unlike classic reciprocal strategies, once mutual cooperation has been observed for a threshold number of rounds they stop checking their co-player’s behaviour every round, and instead only check it with some probability. By doing so, they reduce the opportunity cost of verifying whether the action of their co-player was actually cooperative. We demonstrate that these trust-based strategies can outcompete strategies that are always conditional, such as Tit-for-Tat, when the opportunity cost is non-negligible. We argue that this cost is likely to be greater when the interaction is between people and intelligent agents, because of the reduced transparency of the agent. Consequently, we expect people to use trust-based strategies more frequently in interactions with intelligent agents. Our results provide new, important insights into the design of mechanisms for facilitating interactions between humans and intelligent agents, where trust is an essential factor.     

Motivated learning for the development of autonomous systems

A new machine learning approach known as motivated learning (ML) is presented in this work. Motivated learning drives a machine to develop abstract motivations and choose its own goals. ML also provides a self-organizing system that controls a machine’s behavior based on competition between dynamically-changing pain signals. This provides an interplay of externally driven and internally generated control signals. It is demonstrated that ML not only yields a more sophisticated learning mechanism and system of values than reinforcement learning (RL), but is also more efficient in learning complex relations and delivers better performance than RL in dynamically-changing environments. In addition, this paper shows the basic neural network structures used to create abstract motivations, higher level goals, and subgoals. Finally, simulation results show comparisons between ML and RL in environments of gradually increasing sophistication and levels of difficulty.     

The Protestant Ethic in Hungary

While in the 16–17th centuries about two thirds of Hungarians belonged to the Reformed Church, the presence of the ‘spirit of capitalism’ and the ‘Protestant ethic’ is rather questionable. The Calvinists did not play a different or decisive role in the capitalization process of Hungary at the end of the 19th century. This study is a summary of a much longer analysis of the ‘Hungarian Protestant ethic’ of the 17th century. The historical analysis focuses on the Puritan doctrines which can be found in conduct-books as well as the practical religiosity of Hungarian Puritans and Reformed people in that age. The ‘Hungarian Protestant ethic’ differs from Weber's ideal-type in two respects: the Hungarian version is more pietistic, less activist; and it seems to have less practical influence in everyday life because of weak religiosity. The Hungarian case does not refute Weber's thesis, but it does call attention to two important parts of historical analysis: the reinterpreting, selecting procedure in social context, and the intensity of religiosity.     

Truth and Tension in Science and Religion

While evolution deserves theological support and inclusion in schools, the consensus views, Darwinian or neo-Darwinian evolution, present problems. Darwin presented two arguments: 1) that evolution, descent with modification, has occurred, and 2) that its “cause” is natural selection, the focus of neo-Darwinism. However, the products of natural selection, adaptations, are often not congruent with the lineages produced by evolution and its demonstrated effects are within species. The difficulty of using natural selection to explain evolution is used by proponents of Intelligent Design (ID) to denigrate evolution and to argue for the inclusion of ID in biology classes. However, the force of the arguments in favor of ID disappear when evolution is viewed as an informational phenomenon. Evolution, like development, is a system of increasing complexity, and emergence the inevitable outcome of the transformation of matter whereby the information in DNA is expressed that accompanies energy dynamics. Evolution is witnessed by studies in comparative biology that reveal groups of related organisms and homologies, both the result of descent with modification.     

In Search of the Caliphate

“In Search of the Caliphate” discusses the historic split between Sunni and Shi'ite Islams in religious studies textbooks, general reference resources, multi-volume reference works on Islam, and briefly suggests other resources (monographs and articles). In analyzing textbooks, the article uses a template taken from the Encyclopedia of Religion (2005) and looks for the following characteristics in the discussion: the question of authority and succession in Islam after the death of the Prophet Mohammad; esoteric knowledge and the role of the Imam (particularly in Shi'a); the assassination of Husayn (the grandson of Mohammed); and the appearance of the eschatological figure of the Madhi in Twelver Shi'a. “Twelver Shi'ism” is used as a search term to analyze the information in reference works (both general works and those devoted to Islam). The conclusion highlights the challenges in researching this topic in a university library.     

Bridging the Marketing Gap: A Review of How to Think Like a Behavior Analyst: Understanding the Science That Can Change Your Life by Jon Bailey and Mary Burch

The field of applied behavior analysis has suffered from a relative dearth of user-friendly books appropriate to a lay audience. Bailey and Burch''s book fills this niche with a work that is both entertaining and informative. The book is reviewed in terms of the strengths and limitations of its content, as well as in the context of the importance of effective marketing of behavior analysis.     

The intelligent career framework as a basis for interdisciplinary inquiry

This paper examines how separate behavioral science disciplines can be brought together to more fully understand the dynamics of contemporary careers. We adopt one interdisciplinary framework – that of the “intelligent career” – and use it to examine how separate disciplinary approaches relate to one another. The intelligent career framework suggests careers unfold through three interdependent “ways of knowing” reflecting why, how and with whom people work. Breaking this framework down into six unidirectional links, we examine the contributions made by a variety of behavioral science approaches. Our review suggests that separate bodies of career-relevant theory reflect separate links from one way of knowing to another. We offer several lessons concerned with (a) the intelligent career framework; (b) evidence underlying separate theories; (c) differing definitions of career; (d) research methodologies; (e) time; and (f) interdependence among variables. We conclude with some ideas on how to better promote future interdisciplinary careers research.
