John Nash: Three Phases in the Career of a Beautiful Mind

This article is the Helen Flanders Dunbar Lecture presented at Columbia-Presbyterian Hospital in New York City in 2002, the centennial year of her birth. It focuses on three periods in the evolution of Nash’s mental illness, the predelusional, delusional, and postdelusional periods, and provides a psychoanalytic interpretation of each. Donald Capps is Professor of Pastoral Psychology at Princeton Theological Seminary.

Adversarial attacks against profile HMM website fingerprinting detection model

People are accustomed to using an anonymous network to protect their private information. The Profile HMM (Hidden Markov Model) Website Fingerprinting Detection algorithm can detect the website that the data stream accesses by pattern matching the captured data traffic. This makes the anonymous network lose its effect. In order to bypass the detection of this model, we propose a method based on genetic algorithm to generate adversarial samples. By migrating the problem of adversarial samples in deep learning, our approach is used for the broader machine learning detection model to do traffic confusion, and then achieves the purpose of bypassing the Profile HMM model detection. The key challenge is how to construct a suitable fitness function to generate an effective adversarial sample at minimal cost. The experimental results show that the success rate of our traffic confusion method is as high as 97%. At the same time, we only need to add less perturbation traffic than the traditional traffic confusion method.     

G.A.T.S. and universities: Implications for research

The likely impact of applying the General Agreement on Trade in Services (GATS) to higher education are examined. GATS aims to “open up” services to competition: no preference can be shown to national or government providers. The consequences for teaching are likely to be that private companies, with degree-awarding powers, would be eligible for the same subsidies as public providers. Appealing to the inadequate recently introduced “benchmark” statements as proof of quality, they would provide a “bare bones” service at lower cost. Public subsidies would go: education being reduced to that minimum which could be packaged in terms of verifiable “learning outcomes”. The loss of “higher” aspirations, such education of critically-minded citizens of a democratic and civilised society would impoverish the university’s research culture which demands honesty and openness to public scrutiny. Most university research is substantially supported by public subsidy. Under GATS discipline, commercial providers of research services could be entitled to similar public subsidies. Publicly funded fundamental research would fade, leaving university research totally dependent for funds upon the good will of industry and commerce. Present problems, such as the suppression of unwelcome results and the use of questionable results to manipulate public opinion, would considerably increase. The public would lose a prime source of trustworthy knowledge, needed in political discourse, legal disputation, consumer protection and in many other contexts.     

The ethical implications of the new research paradigm

Research is now an increasingly heterogeneous activity involving an expanded range of new actors and stake-holders and employing an eclectic range of epistemologies and methodologies. The emergence of these new research paradigms — and, in particular, of so-called ‘Mode 2’ knowledge production that is highly contextualised and socially distributed — raises new and challenging ethical issues and also important questions about the autonomy of science and the social responsibilities of scientists.     

A close-up comparison of the misclassification error distance and the adjusted Rand index for external clustering evaluation

The misclassification error distance and the adjusted Rand index are two of the most common criteria used to evaluate the performance of clustering algorithms. This paper provides an in-depth comparison of the two criteria, with the aim of better understand exactly what they measure, their properties and their differences. Starting from their population origins, the investigation includes many data analysis examples and the study of particular cases in great detail. An exhaustive simulation study provides insight into the criteria distributions and reveals some previous misconceptions.     

On presence in the psychoanalytic relation

This paper discusses presence in the psychoanalytic relation, the analysand’s and the analyst’s. Clinical situations with different qualities of presence will be considered focusing on what kind of interplay between analysand and analyst they may lead to. As examples, I have chosen three different clinical situations: In the first there is an interplay between the analysand’s free associations and the analyst’s ‘evenly suspended attention’. In connection with this I will discuss Bion’s concepts of ‘reverie’ and of ‘O’. In the second there is where the interaction is characterised by what Meltzer calls ‘geographical confusion’. In the third there is a ‘transference delusion’ in the psychoanalysis of breakdown as Winnicott describes it.     

How do public transport users adjust their travel behaviour if public transport ceases? A qualitative study

Mode shift from public transport (PT) to private car when a PT shut-down occurs results in an increase in the number of car trips on the road network which may contribute to traffic congestion. Policies aimed at reducing the mode shift to car can be designed through a better understanding of PT users’ mode shift in the event of a PT disruption. Furthermore, the share of car mode shift is also an important parameter for assessing traffic congestion relief associated with day to day PT provision in cities. This study sought to uncover factors influencing the mode shift to car among PT users in the event of a PT disruption. Semi-structured interviews were conducted with 30PT users from Melbourne, Australia. Grounded theory was used to derive categories and subcategories of behavioural responses. Factors affecting mode shift to car if PT ceases in the short term were classified into three main themes with several subcategories: individual-specific factors, context-specific factors and journey-specific factors. In the long term, the analysis reveals that only context-specific factors have an influence on mode shift. Findings show that car access, travel time, travel cost, trip importance, non-central business district (CBD) trips, weather, flexibility and accessibility to PT stations are the most important factors favouring use of the car if PT ceases in the short term. This acts to increase traffic congestion due to the mode shift to car. However, in the long term, removing PT is expected to have an impact on land use, leading to individuals changing their residential and workplace location.     

Active school travel,attitudes and psychological well-being of children

The decline in physical activity levels among children emphasizes a need for research on experiences related to children’s active travel. The present study investigates the relationship between mode use on school trips and psychological well-being (PWB) of children. Data were collected from 152 primary school children in Lower Austria. The paper-and-pencil survey investigated transport-related attitudes, travel behavior, and children’s emotional well-being depending on the travel mode used on their trip to school. Parents’ perceptions of their child’s travel mode on well-being were also collected in 31 in-depth interviews. Findings suggest that active school travel is positively associated with children’s PWB, and that travel-related attitudes towards modes are significantly related to well-being. However, it is difficult to determine the causal direction between the two variables as causal feedback loops can be assumed. Clear results can be obtained for the parental survey: Parents reported strong positive associations between active travel modes and the well-being of their children. More research with bigger sample sizes and higher quality measures should be conducted, including about non-school trips and with longitudinal datasets, to further evaluate the interrelations between children’s mode use, attitudes, and well-being and to determine the most successful strategies for increasing active mobility among children.     

Mental rotation does not account for sex differences in left-right confusion

Several studies have demonstrated that women believe they are more prone to left-right confusion (LRC) than men. However, while some studies report that there is also a sex difference in LRC tasks favouring men, others report that men and women perform equally well. Recently, it was suggested that sex differences only emerge in LRC tasks when they involve mental rotation. That is, sex differences that are reported for some LRC tasks are strongly affected by the well-documented male advantage in mental rotation. To test this assumption, 91 participants were investigated on two LRC tasks: The Left-Right Commands Task and the Bergen Left-Right Discrimination Test. Additionally, participants were asked to complete an LRC self-rating questionnaire. To rule out the possibility that sex differences in LRC are confounded by sex differences in mental rotation, male and female participants were matched for mental rotation performance, resulting in a sample of 46 matched participants. These matched participants showed robust sex differences in favour of men in all LRC measurements. This suggests that pronounced sex differences in LRC are a genuine phenomenon that exists independently of sex differences in mental rotation.
