Birth of an Abstraction: A Dynamical Systems Account of the Discovery of an Elsewhere Principle in a Category Learning Task

Human participants and recurrent (“connectionist”) neural networks were both trained on a categorization system abstractly similar to natural language systems involving irregular (“strong”) classes and a default class. Both the humans and the networks exhibited staged learning and a generalization pattern reminiscent of the Elsewhere Condition (Kiparsky, 1973). Previous connectionist accounts of related phenomena have often been vague about the nature of the networks’ encoding systems. We analyzed our network using dynamical systems theory, revealing topological and geometric properties that can be directly compared with the mechanisms of non‐connectionist, rule‐based accounts. The results reveal that the networks “contain” structures related to mechanisms posited by rule‐based models, partly vindicating the insights of these models. On the other hand, they support the one mechanism (OM), as opposed to the more than one mechanism (MOM), view of symbolic abstraction by showing how the appearance of MOM behavior can arise emergently from one underlying set of principles. The key new contribution of this study is to show that dynamical systems theory can allow us to explicitly characterize the relationship between the two perspectives in implemented models.     

Young women’s construction of their post-cancer fertility

Younger women diagnosed with cancer often face compromised fertility as a result of their treatment. However, previous research has adopted a biomedical model of fertility and utilised hypothetico-deductive research methods which have not allowed for full exploration of women’s subjectivity. This study explored younger women’s construction of their fertility post-cancer, and their discussions of fertility with healthcare professionals, from a social constructionist epistemology. Semi-structured one-to-one interviews were conducted with eight women aged 18–26, across a variety of cancer types. Foucaultian Discourse Analysis identified three subject positions associated with fertility concerns: ‘Inadequate woman: Accepting the motherhood mandate’; ‘Adequate woman: Resisting the motherhood mandate’; and ‘Survival of the fittest: Woman as genetically defective’. Implications of these subject positions included feelings of inadequacy, fear and devastation; feeling undesirable to romantic partners; and concern about passing on cancer-positive genes. In describing healthcare professional interactions, women adopted positions of ‘Satisfied patient’; ‘Passive recipient patient’; or ‘Resisting the passive patient position’. Accounts of inadequate information provision were associated with anger and frustration, whereas feeling adequately informed was associated with satisfaction at making decisions about fertility preservation. These results suggest that fertility is of importance to young women cancer survivors, and that compromised fertility can negatively impact subjectivity.     

Electrical conductivity of Nd and Ce co-doped Gd2Zr2O7 ceramics

In this study, (Gd_{1? x} Nd _x )₂(Zr_{1? x} Ce _x )₂O₇ (0 ≤ x ≤ 0.5) ceramics have been prepared by pressureless sintering at 1973 K to investigate the influence of Nd and Ce co-doping on their electrical conductivity. The electrical conductivity of the ceramics was investigated by impedance spectroscopy measurements from 723 to 1173 K over the frequency range of 20 Hz to 2 MHz in air. The measured values obey the Arrhenius relation. For each composition, the grain conductivity gradually increases with increasing temperature from 723 to 1173 K. At a given temperature, it gradually decreases with increasing neodymium and cerium contents from x = 0 to 0.3; thereafter, the grain conductivity exhibits a slight increase with further increasing neodymium and cerium contents up to x = 0.5.     

What,and Where,Luck is: A Response to Jennifer Lackey

In ‘What Luck Is Not’, Lackey presents counterexamples to the two most prominent accounts of luck: the absence of control account and the modal account. I offer an account of luck that conjoins absence of control to a modal condition. I then show that Lackey's counterexamples mislocate the luck: the agents in her cases are lucky, but the luck precedes the event upon which Lackey focuses, and that event is itself only fortunate, not lucky. Finally I offer an account of fortune. Fortune is luck-involving, and therefore easily confused with luck, but it is not itself lucky.     

Mindfulness and acceptance-based group therapy versus traditional cognitive behavioral group therapy for social anxiety disorder: A randomized controlled trial

Recent research has supported the use of mindfulness and acceptance-based interventions for Social Anxiety Disorder (SAD).     

Offender interviewing in custodial settings: Understanding validity,value and veracity issues

The purpose of this scoping literature review was to identify trends regarding validity, value and veracity issues when conducting (qualitative) interviews with offenders in custodial settings. We selected for review works from electronic databases in SAGE, Springer, and Taylor and Francis by using e-journals, Google Scholar and the behavioural science database, PsycINFO. The inclusion criteria for our studies were based on whether sources addressed offender interviewing as a wellspring of information, but excluded those that focused solely on the acquisition of clinical information (at the expense of focusing on validity, value and veracity issues). We utilised the content analysis approach to identify themes/ patterns in the research findings. Key findings suggest that offenders with impression management motivations deceive and manipulate in their research interview presentations. When gathering data from inmates in custodial care settings, best practice includes cross-checking offender interview data against other sources of evidence and taking into account the context in which they are serving their sentences.     

An exploration of the therapeutic process while using computerised cognitive behaviour therapy

Background: Modern technologies that offer an alternative to face‐to‐face therapy have gained ground in the NHS. Critics have argued that some of the important elements of the therapeutic change process necessarily require a human therapist. Yet, the traditional understanding of the change process in psychotherapy is challenged by evidence that some computerised cognitive behaviour therapy (cCBT) programs may be as effective as face‐to‐face therapy, suggesting that in certain cases the interaction between user and a cCBT product satisfies sufficient criteria for personal change without the need for actual human contact. Aim: This study used the cCBT package Blues Begone as a means of investigating the process by which a computer‐mediated program helped adults with mild depression help themselves. Method: Seven qualitative interviews were conducted with mildly depressed users who had completed Blues Begone in their own homes without any additional human help or support. Findings: Interpretive phenomenological analysis (IPA) was performed with four main themes emerging. These were: the meaningful relationship; shape from confusion; stimulation and empowerment. This study illustrates some of the ways that some depressed users make use of cCBT self help.     

Mother of God: A History of the Virgin Mary

Starting from the context in which there is an increasing emphasis on ecclesial revitalisation and churchplanting, the analytical model of the Australian National Church Life Survey (NCLS) research is introduced and described in its background and characteristics. The model shows particular interest in a specific church profile which is created based on local church surveys. The article describes the profile, examines the theological concepts and argues for in-depth empirical research in a Dutch context concerning the use of the profile.     

The Second Vatican Council 50th anniversary: visions and re-visions

On 21 November 2014, the 50th anniversary of the solemn promulgation of Lumen Gentium and Unitatis Redintegratio was celebrated. Between ‘aggiornamento’ and ‘ressourcement’ the Catholic Church had been striving to understand itself and its Tradition more precisely, in order to be newly relevant, lastingly true and authoritative in the future ? an indispensible task, if the gospel were to be proclaimed to the contemporary world, but not an easy one. It is little wonder that this completion of the Council's endeavours was preceded by its so-called ‘black week’. Questions remain as to the outcome of it all, and the articles assembled in this issue assess the reception of these two conciliar texts after 50 years. Where do the achievements lie? Where are the shortcomings? Where do questions need to be asked today that reach beyond the horizon of Vatican II?
