The Variety of Lattice Effect Algebras Generated by MV-algebras and the Horizontal Sum of Two 3-element Chains

It has been recently shown [4] that the lattice effect algebras can be treated as a subvariety of the variety of so-called basic algebras. The open problem whether all subdirectly irreducible distributive lattice effect algebras are just subdirectly irreducible MV-chains and the horizontal sum of two 3-element chains is in the paper transferred into a more tractable one. We prove that modulo distributive lattice effect algebras, the variety generated by MV-algebras and is definable by three simple identities and the problem now is to check if these identities are satisfied by all distributive lattice effect algebras or not.

Effect of Landmark Type on Route Memory in Unfamiliar Homogenous Environment

Landmarks are objects that have salience that is either visual, semantic or structural. Recent researches have pointed out observer characteristics that make a landmark salient. These have been termed cognitive salience. This study investigated the effects of two components of cognitive salience, familiarity and degree of recognition, on route memory. The first experiment examined the effect of familiarity of landmark and ease with which it could be recognized (degree of recognition) on remembering a route, while in the second experiment only degree of recognition was varied while holding familiarity constant. Two types of landmarks (text and image) were shown to participants who had to recollect course taken at decision points during wayfinding tasks. Participants were shown navigation videos generated using Squareland Model. The videos had six decision points each having one landmark, and the participants were required to indicate the direction of the turn when the landmarks were shown again. Results showed that pictorial landmarks (high degree of recognition) were better facilitators of route memory than textual landmarks (low degree of recognition). Results also indicated that familiar buildings served as better landmarks than unfamiliar buildings. In the second experiment another level of degree of recognition (medium) was added and compared with high and low levels. Results confirmed the findings of the first experiment with high degree of recognition being the best facilitator followed by medium and low degree of recognition. Our findings lend empirical support to the concept of cognitive salience proposed by Caduff and Timpf (Cogn Process 9:249–267, 2008) and highlight the importance of observer characteristics in determining what constitutes as good landmark.     

The Structure of Domination Today: A Lacanian View

Two topics determine today's liberal tolerant attitude towards Others: the respect of Otherness and the obsessive fear of harassment: the Other is OK insofar as its presence is not intrusive, insofar as the Other is not really Other. The central human right in late-capitalist society, namely the right to be free from all harassment by the Other including the violent imposition of ethical norms, contrasts sharply with the violent imposition of divine Mosaic law – the Decalogue – from which the idea of human rights ultimately derives. The underlying discursive shift can be analyzed with the help of Lacan: the discourse of the Master had been replaced by university discourse. While the Master's decision is per se violent, university discourse is enunciated from the position of neutral Knowledge. The truth of the university discourse is power: the constitutive lie of the university discourse is that it disavows its performative dimension, presenting what effectively amounts to a political decision based on power as a simple insight into the factual state of things.     

The Problem of Behaviour Change: From Social Norms to an Ingroup Focus

Social norms are of increasing interest to public policy experts and those conducting behaviour change interventions (e.g. safe driving, recycling). While there is agreement that social norms play a central role in explaining behaviour, such consensus is lacking when it comes to explaining the process through which this occurs. Economics, social marketing and political science focus on individual self‐interest and goal satisfaction and social (dis)approval. In contrast social psychology also incorporates collective interests through its analysis of social identity and ingroup processes. To fully understand behaviour change, it is argued that greater engagement is needed with the links between shifts in social identity, and ingroup norms. As definitions of who “we” are shift, so too does what “we” do. Implications for behaviour change interventions are discussed.     

Perceived Parental Protectiveness Promotes Positive Friend Influence

Friend influence over prosocial behaviour and delinquent behaviour was examined as a function of relative parental protectiveness in a community sample of Lithuanian high school students (M = 16.5 years old). Participants completed self‐reports describing commitment to personal values, delinquent behaviours, prosocial behaviours, and perceived parental protectiveness. Mutual friends (158 male dyads, 241 female dyads) were identified from peer nominations. Distinguishable dyad Actor–Partner Interdependence Model analyses illustrate how parenting promotes positive peer influence. The results indicate that friend influence is greatest in the context of protective parenting: Adolescents who perceived more parental protectiveness were positively influenced by the strength of their friend's personal values, whereas adolescents who perceived less parental protectiveness were not.

Neurophysiologic markers of primary motor cortex for laryngeal muscles and premotor cortex in caudal opercular part of inferior frontal gyrus investigated in motor speech disorder: a navigated transcranial magnetic stimulation (TMS) study

Transcranial magnetic stimulation studies have so far reported the results of mapping the primary motor cortex (M1) for hand and tongue muscles in stuttering disorder. This study was designed to evaluate the feasibility of repetitive navigated transcranial magnetic stimulation (rTMS) for locating the M1 for laryngeal muscle and premotor cortical area in the caudal opercular part of inferior frontal gyrus, corresponding to Broca’s area in stuttering subjects by applying new methodology for mapping these motor speech areas. Sixteen stuttering and eleven control subjects underwent rTMS motor speech mapping using modified patterned rTMS. The subjects performed visual object naming task during rTMS applied to the (a) left M1 for laryngeal muscles for recording corticobulbar motor-evoked potentials (CoMEP) from cricothyroid muscle and (b) left premotor cortical area in the caudal opercular part of inferior frontal gyrus while recording long latency responses (LLR) from cricothyroid muscle. The latency of CoMEP in control subjects was 11.75 ± 2.07 ms and CoMEP amplitude was 294.47 ± 208.87 µV, and in stuttering subjects CoMEP latency was 12.13 ± 0.75 ms and 504.64 ± 487.93 µV CoMEP amplitude. The latency of LLR in control subjects was 52.8 ± 8.6 ms and 54.95 ± 4.86 in stuttering subjects. No significant differences were found in CoMEP latency, CoMEP amplitude, and LLR latency between stuttering and control-fluent speakers. These results indicate there are probably no differences in stuttering compared to controls in functional anatomy of the pathway used for transmission of information from premotor cortex to the M1 cortices for laryngeal muscle representation and from there via corticobulbar tract to laryngeal muscles.     

Creating a Self-Plagiarism Research Topic Typology through Bibliometric Visualisation

Self-plagiarism, textual recycling and redundancy seemed to be controversial and unethical; however some questions about its definition are still open. The objective in this paper presented study was to use bibliometric analysis to synthesise and visualize the research literature production and derive a typology of self-plagiarism research. Five topics emerged: Self-plagiarism, Institutional self-plagiarism, Self-plagiarism and ICT, Self-plagiarism in academic writing, Self-plagiarism in science. The state of the art topics seem to be “social medium”, “virtual world”, “face book”, “sociomateriality”, “knowledge sharing”, “open access”, “institutional repository”, “retraction” and “responsible conduct”.

Emotional Creativity and Real-Life Involvement in Different Types of Creative Leisure Activities

The role of emotional creativity in practicing creative leisure activities and in the preference of college majors remains unknown. This study aims to explore how emotional creativity measured by the Emotional Creativity Inventory (ECI; Averill, 1999) is interrelated with the real-life involvement in different types of specific creative leisure activities and with four categories of college majors. Data were collected from 251 university students, university graduates, and young adults (156 women and 95 men). Art students and graduates scored significantly higher on the ECI than other majors. Humanities scored significantly higher than technical/economic majors. Five creative leisure activities were significantly correlated with the ECI, specifically, writing, painting, composing music, performing drama, and do-it-yourself home improvement.
