The effects of the dopamine D1 receptor antagonist SCH23390 on memory reconsolidation following reminder-activated retrieval in day-old chicks

This series of experiments examined the involvement of the dopamine D1 receptor antagonist, SCH23390, on memory reconsolidation following reminder-activated retrieval. Day-old male New HampshirexWhite Leghorn chicks were trained on a single trial passive avoidance task. A dose of 0.5 mg/kg of SCH23390 was administered subcutaneously 5 min before reminder trials, which were presented at 30, 60, and 90 min following training. Memory deficits were observed when reminder trials were presented at 30 and 60 min following training, but not when a reminder was presented at 90 min. No effect on memory retention was observed when reminder trials were not presented, suggesting that reconsolidation mechanisms were both contingent on the presentation of the reminder and independent of the consolidation process. Following a reminder presented at 60 min post-training, deficits in memory retention emerged between 45 and 60 min. The deficit was prolonged, lasting for up until 48 h after reminder presentation. The results indicate an important role for the D1 receptor in reconsolidation processes.     

The challenge of raising ethical awareness: A case-based aiding system for use by computing and ICT students

Students, the future Information and Communication Technology (ICT) professionals, are often perceived to have little understanding of the ethical issues associated with the use of ICTs. There is a growing recognition that the moral issues associated with the use of the new technologies should be brought to the attention of students. Furthermore, they should be encouraged to explore and think more deeply about the social and legal consequences of the use of ICTs. This paper describes the development of a tool designed to raise students’ awareness of the social impact of ICTs. The tool offers guidance to students undertaking computing and computer-related courses when considering the social, legal and professional implications of the actions of participants in situations of ethical conflict. However, unlike previous work in this field, this tool is not based on an artificial intelligence paradigm. Aspects of the theoretical basis for the design of the tool and the tool’s practical development are discussed. Preliminary results from the testing of the tool are also discussed.

The role of dark pattern stimuli and personality in online impulse shopping: An application of S-O-R theory

Online impulse shopping is a growing industry. This paper uses the Stimulus-Organism-Response framework to model online impulse purchase behavior using a novel combination of stimuli and organism characteristics. The stimuli: social proof, limited-quantity scarcity, and high-demand, are three commonly used website features known as dark patterns. The organism characteristic personality is measured by the big 5 personality traits and persona generated through latent profile analysis. Using the machine learning algorithm XGBoost, impulse purchasing response was predicted separately for each dark pattern stimuli. Results show personality characteristics are important features when predicting consumer impulse purchasing in response to dark pattern messages. Moreover, the personality traits (and personas) most predictive of impulse shopping behavior varied by type of dark pattern. Findings suggest personality influences susceptibility to different dark patterns, indicating a need for tailored interventions to mitigate individual consumer vulnerabilities to impulse shopping.     

Therapist + Social Media = Mental health influencer? Considering the research focusing upon key ethical issues around the use of social media by therapists

Current ethical guidelines for therapists who make use of social media are very limited. As a consequence, they leave much open to interpretation by professionals, an openness that may place the public and professionals at risk. This is particularly of note as therapists are increasingly making use of social media and many professionals are taking on roles as mental health influencers, both purposefully and without realising. Such developments raise many important ethical issues including considerations around influencer competency, integrity, the maintenance of confidentiality and risk management. These issues are briefly discussed in this paper alongside related current research focusing upon them. It is concluded that, despite the existence of ethical guidelines focusing upon social media use by therapists, current research suggests that therapists are not consistently following these guidelines. Moreover, it is argued that researchers and professional bodies, and their associated good practice guidelines, need to keep abreast of new developments to account for changes in social media usage.     

The Creative Industries Entrepreneur: An Analysis of Lived Experience

Expanding our understanding of the lived experience of individuals who use their creativity to realize entrepreneurial opportunity is the primary aim of this paper. Interpretative Phenomenological Analysis is used, based on two interviews of one-hour duration, with eight participants. The key contribution of this research is the recognition of the Creative Industries Entrepreneur. A Creative Industries Entrepreneur is an individual who occupies a space between traditional entrepreneurship theory and established creativity models. The main driving force in opportunity formation for a Creative Industries Entrepreneur is their creative impulse. This pushes them to achieve a personhood, which can reconcile intrinsic impulses with external market forces and social imperatives.     

Sensory effects on judgments of short time-intervals

Two experiments were conducted to test the effect of nontemporal factors on duration discrimination. In Exp. 1, a forced-choice adaptive procedure with a standard duration of 400 or 800 ms was employed. It was shown that, for both auditory and visual modes, the discrimination is better with empty intervals (a silent period between two brief signals) than with filled intervals (a continuous signal), but only with shorter durations. In a second experiment, where intervals of the same duration range were employed but were presented with a single-stimulus method, discrimination was better with empty than with filled intervals, and this effect applied to both ranges of duration and both sensory modes. In both experiments, discrimination was better in the auditory than in the visual mode. These data are discussed in the context of current models of timing mechanisms.

The Theodicy of Austin Farrer

This article seeks to place the theodicy of the Anglican theologian Austin Farrer, as expressed in Love Almighty and Ills Unlimited (1962), within the context of philosophical and theological approaches to the so-called “problem of evil”. Farrer's work is initially contrasted with the theodicies of John Hick and Richard Swinburne. This comparison reveals some of the rationalist and foundationalist moral assumptions of modern philosophical theodicy of which Hick and Swinburne are representatives. By contrast, it is argued that Farrer's approach is thoroughly theological and begins not with a pre-conceived ethics, but with God's self-revelation in Jesus Christ. Farrer is thus deemed to have much in common with pre-Enlightenment thinkers such as Augustine and Aquinas. Although Farrer's theodicy is seen to be theological (rather than a philosophical attempt at a resolution of the modern “problem of evil”), it is argued that he resists trends in recent theological approaches to theodicy that claim that God is passible (for example, the work of Jürgen Moltmann). This article defends divine impassibility and argues that, although Farrer's later “metaphysical personalism” implies that God may be personal to the point that he could be said to suffer, his Augustinian notion of the nature of evil as privatio boni strongly implies impassibility. This Farrer is seen to avoid two anthropomorphic approaches to theodicy: one that judges God by the standards of a foundational secular morality, and the other that ascribes certain “personal” emotions to the divine. This article defends Farrer's theological approach to theodicy and his emphasis on ecclesiology and soteriology. However, the lack of a convincing and thorough dogmatic theology is seen to render his theodicy uncompelling. Despite this weakness, it is argued that Farrer's work points theodicy towards a theological encounter with particular narratives of evil and suffering and away from the consideration of a single “problem of evil” by means of “rational”, philosophical enquiry.     

Human and Machine Interpretation of Expressions in Formal Systems

This paper uses a proof of Gödels theorem, implemented on a computer, to explore how a person or a computer can examine such a proof, understand it, and evaluate its validity. It is argued that, in order to recognize it (1) as Gödel's theorem, and (2) as a proof that there is an undecidable statement in the language of PM, a person must possess a suitable semantics. As our analysis reveals no differences between the processes required by people and machines to understand Gödel's theorem and manipulate it symbolically, an effective way to characterize this semantics is to model the human cognitive system as a Turing Machine with sensory inputs.
