Popper or Kuhn: Truth and the progress of science

The questions of whether science pursues truth as correspondence to reality and whether science in fact progresses towards attaining a truthful understanding of physical reality are fundamental and contested in the philosophy of science. On one side of the debate stands Popper, who argues that science is objective, necessarily assumes a correspondence theory of truth, and inevitably progresses toward truth as physical theories develop, gaining a more truthful understanding of reality through progressively more sophisticated empirical analysis. Conversely Kuhn, influenced by postmodern philosophy, argues that ultimate truth cannot be attained since no objective metaphysical reality exists and it cannot be known, and consequently the notion of scientific objectivity and "progress" is a myth, marred by philosophical and ideological value judgments. Ultimately, Kuhn reduces so-called scientific progress through the adoption of successive paradigms to leaps of "faith". This paper seeks a reconciliation of the two extremes, arguing that Popper is correct in the sense that science assumes a correspondence theory of truth and may progress toward truth as physical theories develop, while simultaneously acknowledging with Kuhn that science is not purely objective and free of value judgments. The notion of faith is also critical, for it was the acknowledgement of God's existence as the creator and instituter of observable natural laws which allowed the development of science and the scientific method in the first place. Therefore, accepting and synthesising the contentions that science is to some extent founded on faith, assumes and progresses toward truth, and is subject to value judgments is necessary for the progress of science.

"It's not the Jedi way!": Moral ambivalence and delivering the 'good' in Star Wars

This article examines the nature of good and evil through the prism of Star Wars, arguing that the ostensible dichotomy between the ‘good’ Jedi and the ‘evil’ Sith is false, and instead both the Jedi and the Sith engage in violence, which is evil. Anakin Skywalker then arrives as the Christ-figure who becomes evil and ‘dies’ to destroy the old rigid law of the letter adhered to by the Jedi, before resurrecting and sacrificing himself to defeat the Sith transgressors. As Milbank argues, the act of selfless love by Anakin as the Christ-figure therefore produces the good, the end of violent conflict which is ontological peace, and institutes the law of love which leads to life and peace.

What is a “Christian” jurisprudence?

The term ‘jurisprudence’ is derived etymologically from the Latin juris, meaning law, and prudentia, meaning wisdom. So jurisprudence simply means the wisdom of the law, or, as it has come to mean in scholarly legal circles these days, the theory of law. It asks fundamental questions regarding the nature and definition of law. And so, the question I wish to pose to us today is what does a truly “Christian” theory of law look like? One that is faithful to, as taken from the conference brochure, the “historic Christian faith” in its “principles and practice”. To contextualise this question, I must give you a deceptively brief and superficial overview of prevailing theories of law – and for those of you who know more about the topic, I apologise for the crass nature of my summary – time prevents me from doing any more...

Sovereignty, surveillance and speeding: Considering the Panopticon as a method of policing

This paper argues that the Panopticon is an accurate model for and illustration of policing and security methods in the modern society. Initially, I overview the theoretical concept of the Panopticon as a structure of perceived universal surveillance which facilitates automatic obedience in its subjects as identified by the theorists Jeremy Bentham and Michel Foucault. The paper subsequently moves to identify how the Panopticon, despite being a theoretical construct, is nevertheless instantiated to an extent through the prevalence of security cameras as a means of sovereignly regulating human conduct; speeding is an ordinary example. It could even be contended that increasing surveillance according to the model of the Panopticon would reduce the frequency of offences. However, in the final analysis the paper considers that even if adopting an approach based on the Panopticon is a more effective method of policing, it is not necessarily a more desirable one.

Mutations in known monogenic high bone mass loci only explain a small proportion of high bone mass cases

High bone mass (HBM) can be an incidental clinical finding; however, monogenic HBM disorders (eg, LRP5 or SOST mutations) are rare. We aimed to determine to what extent HBM is explained by mutations in known HBM genes. A total of 258 unrelated HBM cases were identified from a review of 335,115 DXA scans from 13 UK centers. Cases were assessed clinically and underwent sequencing of known anabolic HBM loci: LRP5 (exons 2, 3, 4), LRP4 (exons 25, 26), SOST (exons 1, 2, and the van Buchem's disease [VBD] 52-kb intronic deletion 3'). Family members were assessed for HBM segregation with identified variants. Three-dimensional protein models were constructed for identified variants. Two novel missense LRP5 HBM mutations ([c.518C>T; p.Thr173Met], [c.796C>T; p.Arg266Cys]) were identified, plus three previously reported missense LRP5 mutations ([c.593A>G; p.Asn198Ser], [c.724G>A; p.Ala242Thr], [c.266A>G; p.Gln89Arg]), associated with HBM in 11 adults from seven families. Individuals with LRP5 HBM ( approximately prevalence 5/100,000) displayed a variable phenotype of skeletal dysplasia with increased trabecular BMD and cortical thickness on HRpQCT, and gynoid fat mass accumulation on DXA, compared with both non-LRP5 HBM and controls. One mostly asymptomatic woman carried a novel heterozygous nonsense SOST mutation (c.530C>A; p.Ser177X) predicted to prematurely truncate sclerostin. Protein modeling suggests the severity of the LRP5-HBM phenotype corresponds to the degree of protein disruption and the consequent effect on SOST-LRP5 binding. We predict p.Asn198Ser and p.Ala242Thr directly disrupt SOST binding; both correspond to severe HBM phenotypes (BMD Z-scores +3.1 to +12.2, inability to float). Less disruptive structural alterations predicted from p.Arg266Cys, p.Thr173Met, and p.Gln89Arg were associated with less severe phenotypes (Z-scores +2.4 to +6.2, ability to float). In conclusion, although mutations in known HBM loci may be asymptomatic, they only account for a very small proportion ( approximately 3%) of HBM individuals, suggesting the great majority are explained by either unknown monogenic causes or polygenic inheritance.

Conversation Pieces

This curated exhibition presented works by Australian artists Agatha Gothe-Snape, Alex Martinis Roe and Hannah Raisin and collaborative works by Catherine or Kate (Catherine Sagin and Kate Woodcroft), Scott Ferguson (Erika Scott and Brooke Ferguson) and Courtney Coombs and Caitlin Franzmann. These artists engage with ideas of contemporary feminism through processes of dialogue and exchange, exploring subjectivity, humour and intimacy in performance and installation artworks. These works are generated by physical, verbal or textual dialogues between collaborators, participants or the artist and audience; and spark a conversation about contemporary feminist art practice in Australia today.

Effect of gaze position and blur on stepping accuracy in older adults.

Purpose: To examine the effects of gaze position and optical blur, similar to that used in multifocal corrections, on stepping accuracy for a precision stepping task among older adults. Methods: Nineteen healthy older adults (mean age, 71.6 +/- 8.8 years) with normal vision performed a series of precision stepping tasks onto a fixed target. The stepping tasks were performed using a repeated-measures design for three gaze positions (fixating on the stepping target as well as 30 and 60 cm farther forward of the stepping target) and two visual conditions (best-corrected vision and with +2.50DS blur). Participants' gaze position was tracked using a head-mounted eye tracker. Absolute, anteroposterior, and mediolateral foot placement errors and within-subject foot placement variability were calculated from the locations of foot and floor-mounted retroreflective markers captured by flash photography of the final foot position. Results: Participants made significantly larger absolute and anteroposterior foot placement errors and exhibited greater foot placement variability when their gaze was directed farther forward of the stepping target. Blur led to significantly increased absolute and anteroposterior foot placement errors and increased foot placement variability. Furthermore, blur differentially increased the absolute and anteroposterior foot placement errors and variability when gaze was directed 60 cm farther forward of the stepping target. Conclusions: Increasing gaze position farther ahead from stepping locations and the presence of blur negatively impact the stepping accuracy of older adults. These findings indicate that blur, similar to that used in multifocal corrections, has the potential to increase the risk of trips and falls among older populations when negotiating challenging environments where precision stepping is required, particularly as gaze is directed farther ahead from stepping locations when walking.

Law student lifestyle pressures

One significant factor influencing student wellbeing is the degree to which their studies are subject to external lifestyle pressures. These pressures are relieved or exacerbated by choices students make around their approaches to study, and the amount of time they devote to work and leisure. This Chapter considers results from a 2012 survey of law students at the University of New South Wales (UNSW), Sydney, Australia. Those results are compared to results from a similar US law student survey, and comparable data from the UK and Australia more broadly. In addition, the UNSW study compares key lifestyle choices of undergraduate (LLB) and graduate (JD) law students. The significance of the analysis in this Chapter for understanding law students’ wellbeing is that comparing American and Australian law students’ lifestyle patterns provides insights into contextual variation between both groups, which is important to bear in mind when comparing American and Australian research on law students’ wellbeing, and appreciating the limits of such comparisons. In particular, much of the wellbeing literature to date has focused on course-based stressors, but in light of recent research indicating that improvements in students’ course-based experiences may not have a direct effect on law students’ elevated levels of psychological distress, it is important to understand the broader life pressures and stressors that may be impacting law students’ wellbeing.

The relationship between class participation and law students' learning, engagement and stress: Do demographics matter?

Student participation in the classroom has long been regarded as an important means of increasing student engagement and enhancing learning outcomes by promoting active learning. However, the approach to class participation common in U.S. law schools, commonly referred to as the Socratic method, has been criticised for its negative impacts on student wellbeing. A multiplicity of American studies have identified that participating in law class discussions can be alienating, intimidating and stressful for some law students, and may be especially so for women, and students from minority backgrounds. Using data from the Law School Student Assessment Survey (LSSAS), conducted at UNSW Law School in 2012, this Chapter provides preliminary insights into whether assessable class participation (ACP) at an Australian law school is similarly alienating and stressful for students, including the groups identified in the American literature. In addition, we compare the responses of undergraduate Bachelor of Laws (LLB) and graduate Juris Doctor (JD) students. The LSSAS findings indicate that most respondents recognise the potential learning and social benefits associated with class participation in legal education, but remain divided over their willingness to participate. Further, in alignment with general trends identified in American studies, LLB students, women, international students, and non-native English speakers perceive they contribute less frequently to class discussions than JD students, males, domestic students, and native English speakers, respectively. Importantly, the LSSAS indicates students are more likely to be anxious about contributing to class discussions if they are LLB students (compared to their JD counterparts), and if English is not their first language (compared to native English speakers). There were no significant differences in students’ self-reported anxiety levels based on gender, which diverges from the findings of American research.
