A high-speed algorithm for computing conditional probabilities of substrings of sequentially observed data

An algorithm is described that computes relative frequencies of occurrence of all arbitrarily long substrings of sequential data, such as are obtained from experiments in learning/memory and verbal interaction. The algorithm offers high speed and provides systematization for the computation of empirical conditional probabilities. Use of this algorithm allows application of probabilistic and information theoretic disciplines to reveal dependencies between events separated arbitrarily in time.

Conflict Minerals in Electronic Systems: An Overview and Critique of Legal Initiatives

The Democratic Republic of Congo has vast natural resources, many of which are regularly exploited by the electronics industry. Unfortunately, in addition to these resources, there are widespread human rights abuses committed by armed groups entrenched in the eastern part of the Democratic Republic of Congo. These armed groups are using profits from these minerals as a source of funding. Their human rights abuses have led to a growing humanitarian interest in the region and prompted the international community to action. This paper explores the conflicts in the Democratic Republic of Congo, provides an understanding of the link between human rights abuses and conflict minerals, and interprets and critiques the legal actions of the international community.     

Kant’s Solution to the Euthyphro Dilemma

Are our actions morally good because we approve of them or are they good independently of our approval? Are we projecting moral values onto the world or do we detect values that are already there? For many these questions don’t state a real alternative but a secular variant of the Euthyphro dilemma: If our actions are good because we approve of them moral goodness appears to be arbitrary. If they are good independently of our approval, it is unclear how we come to know their moral quality and how moral knowledge can be motivating. None of these options seems attractive; the source of moral goodness unclear. Despite the growing literature on Kant’s moral epistemology and moral epistemology the question remains open what Kant’s answer to this apparent dilemma is. The Kantian view I attempt to lay out in this paper is supposed to dissolve the secular version of the Euthyphro dilemma. In responding to this dilemma we need to get clear about the source or the origin of our moral knowledge: Voluntary approval or mind-independent moral facts? Projectivism or detectivism? Construction or given? I believe that all these ways of articulating the problem turn out, on closer inspection, to be false alternatives.     

Revisiting self-regulatory techniques to promote physical activity in older adults: null-findings from a randomised controlled trial

Objective. A randomised controlled trial (RCT) was conducted to evaluate a three-hour face-to-face physical activity (PA) intervention in community-dwelling older German adults with four groups: The intervention group (IG) received behaviour change techniques (BCTs) based on the health action process approach plus a views-on-ageing component to increase PA. The second intervention group ‘planning’ (IGpl) contained the same BCTs, only substituted the views-on-ageing component against an additional planning task. An active control group received the same BCTs, however, targeting volunteering instead of PA. A passive control group (PCG) received no intervention.

Design. The RCT comprised 5 time-points over 14 months in N = 310 participants aged 64+.

Main outcome measures. Self-reported as well as accelerometer-assessed PA.

Results. Neither PA measure increased in the IG as compared to the other groups at any point in time. Bayes analyses supported these null-effects.

Conclusion. A possible explanation for this null-finding in line with a recent meta-analysis is that some self-regulatory BCTs may be ineffective or even negatively associated with PA in interventions for older adults as they are assumed to be less acceptable for older adults. This interpretation was supported by observed reluctance to participate in self-regulatory BCTs in the current study.     

Secondary self‐deception

According to doxastic accounts of self‐deception, self‐deception that P yields belief that P. For doxastic accounts, the self‐deceiver really believes what he, in self‐deception, professes to believe. I argue that doxastic accounts are contradicted by a phenomenon that often accompanies self‐deception. This phenomenon – which I term ‘secondary deception’ – consists in the self‐deceiver's defending his professed (deceit‐induced) belief to an audience by lying to that audience. I proceed to sketch an alternative, non‐doxastic account of how we should understand self‐deception in terms of the self‐deceiver's misrepresentation of himself as believing that P.
