Experimental Philosophy on Free Will and Determinism

<p>In the debate over whether free will is compatible with determinism most philosophers on both sides think that folk intuitions are a constraint on philosophical theorising. Most also think that the same criteria are required for free will in all cases. But recent attempts to empirically study folk intuitions about free will appear to show that these two positions cannot be jointly maintained. That is because folk intuitions about free will appear to represent compatibilist and incompatibilist criteria for free will in different cases. In response to this some philosophers have run new studies to demonstrate problems with older ones and undermine their results. One such study has been claimed to show that some participants mistakenly inferred that an agent‘s mental states have no effect on their actions given determinism. In this thesis I argue that the questions about causation that were used in this study were too ambiguous to show this. My central point is that when considering the causal history of an action we tend to privilege the earlier causes over later ones. When participants responded that an agent‘s mental states have no effect on their actions they may have meant that there were earlier conditions that caused the agent‘s mental states which then caused their actions. This would show that the participants had made the correct inference that given determinism the causal histories of an agent‘s actions extend back in time to events outside of the agent‘s mind. Thus the problem of the apparent mismatch between folk intuitions and philosophical theories of free will remains. I also suggest that the results of these studies also appear to demonstrate a greater level of disagreement among folk intuitions about the same cases than philosophers seem to expect. This raises questions about whether the same theory of free will has to apply to everyone, and if so, whether folk intuitions support any such theory. In chapter one I begin by briefly describing the free will debate and the role that folk intuitions usually play within it. I describe some debate over the usefulness of folk intuitions in philosophy, and make some small contributions on behalf of their usefulness. I describe and defend the recent movement towards attempting to empirically study folk intuitions on philosophical issues. In chapter two I describe the empirical studies that seem to show that folk intuitions about free will represent compatibilist criteria in some cases and incompatibilist criteria in others. I suggest that they also seem to show that when considering the same case some folk have compatibilist intuitions and some have incompatibilist intuitions. I raise some questions about the implications of rejecting the assumption, which most philosophers seem to make, that people generally have the same intuitions about the same cases. In chapter three I present the study that is claimed to show that participants in the earlier studies were confused, and thus that they did not really have incompatibilist intuitions. I present my arguments against it and conclude that for now the original interpretation of those studies stands, along with the problems it raises.</p>

Making Strides in Doctoral-Level Career Outcomes Reporting: Surveying the Landscape of Classification and Visualization Methodologies and Creating a Crosswalk Tool

The recent movement underscoring the importance of career taxonomies has helped usher in a new era of transparency in PhD career outcomes. The convergence of discipline-specific organizational movements, interdisciplinary collaborations, and federal initiatives have all helped to increase PhD career outcomes tracking and reporting. Transparent and publicly available PhD career outcomes are being used by institutions to attract top applicants, as prospective graduate students are factoring these in when deciding on the program and institution in which to enroll for their PhD studies. Given the increasing trend to track PhD career outcomes, the number of institutional efforts and supporting offices for these studies have increased, as has the variety of methods being used to classify and report/visualize outcomes. This report identifies and summarizes currently available PhD career taxonomy tools, resources, and visualization options to help catalyze and empower institutions to develop and publish their own PhD career outcomes. Similar fields between taxonomies were mapped to create a new crosswalk tool. This work serves as an empirical review of the career outcome tracking systems available and highlights organizations, consortia, and funding agencies that are impacting policy change toward greater transparency in PhD career outcomes reporting.

Bypassing use-dependent plasticity in the primary motor cortex to preserve adaptive behavior

Behavioral adaptation, a central feature of voluntary movement, is known to rely on top-down cognitive control. For example, the conflict-adaptation effect on tasks such as the Stroop task leads to better performance (e.g. shorter reaction time) for incongruent trials following an already incongruent one. The role of higher-order cortices in such between-trial adjustments is well documented, however, a specific involvement of the primary motor cortex (M1) has seldom been questioned. Here we studied changes in corticospinal excitability associated with the conflict-adaptation process. For this, we used single-pulse transcranial-magnetic stimulation (TMS) applied between two consecutive trials in an interference flanker task, while measuring motor-evoked potentials (MEPs) after agonistic and antagonistic voluntary movements. In agonist movement, MEP amplitude was modulated by recent movement history with an increase favoring movement repetition, but no significant change in MEP size was observed whether a previous trial was incongruent or congruent. Critically, for an antagonist movement, the relative size of MEPs following incongruent trials correlated positively with the strength of behavioral adaptation measured as the degree of RT shortening across subjects. This post-conflict increase in corticospinal excitability related to antagonist muscle recruitment could compensate for a potential deleterious bias due to recent movement history that favors the last executed action. Namely, it prepares the motor system to rapidly adapt to a changing and unpredictable context by equalizing the preparation for all possible motor responses.

Development of Customised Wheelchair Racing Gloves Using Digital Fabrication Techniques

Wheelchair racing gloves are typically solid 3D structures held in a clenched fist which help to propel the chair by pushing the glove against a rotating rail which is attached to the wheel to drive the wheelchair forward. There has been a recent movement towards developing customisable gloves using 3D scanning technique, however, currently there are no commercial offerings which allow for product customisation without being prohibitively expensive. The aim of this project, therefore, was to develop a scalable method for producing customised wheelchair racing gloves in a cost-effective way. The generated 3D forms were 3D printed in a variety of infill densities and finished with a grip liner. These 3D printed gloves were compared in terms of fit and perception of performance, and for their mass, cost and energy/power cost. The 3D printed gloves provided a substantially reduced mass with only a minimal reduction in overall strength at a comparable cost to the solid equivalent.

“Belonging to a Homeland in Order to not Need it Anymore”

In his book After Europe, the Bulgarian political theorist Ivan Krastev observes the ‘free fall’ of the dominant grand narrative in Europe after 1989, Fukuyama’s idea of the ‘End of history’. If we want to understand why we must pay attention both to the ‘periphery’ of this narrative, as well as to the periphery of Europe, where the recent movement of migration in the refugee crisis is experienced from a nationalist déjà vu mindset and not welcomed, we have to rethink the phenomenon of nationalism and patriotism, and the difference between the two. After a short phenomenology of the diverse combinations of ‘love’ (among other meanings the love for my patria) and ‘justice’, the author concludes that a strict separation of patriotism and nationalism is hardly possible. And even more fundamental, there will always be a tension between love and justice or, in philosophical terms, between the particular and the universal. Following Krastev, the autor holds that the contemporary rise of populist movements and of ‘illiberal democracy’ points to the crisis of a meritocratic idea of liberal democracy. One longs for a form of belonging that is not the result of our performance but that is unconditional, as Jean Améry argued in his reflections on the meanings of a homeland (Heimat).

Evolusi dan Adaptasi Gerakan Kebangsaan Orang Papua dari Nasionalisme ke Etnonasionalisme

Papuan social, cultural and political resistance, especially the recent movement of Papuan students and youth (August-September 2019) which is affect as a loss of dignity of Papuan constructed by non-Papuan in some cities in Java was not an unpredictable occurrence. Edwars Lorenz’s theory of Chaos and Peter Ho’s theory of Black Elephant have been giving any clear academical framework to illustrate what will be happened. After academician such as Manuel Castells, Will Kymlica, etc. also have been giving other big picture of academical framework about what have been done, what is still moving, and what will be happen in term of connectivity of social, cultural, and political among Papuan, Central Government, and non-Papuan in Indonesia. Moreover, what is happened, Nassim Nicholas Taleb has been introducing theory of Black Swan for analyzed any shocking elements which will be occurred if an integration effort in term of peace and democratic ways are not giving a win-win solution. In this paper, how to analyzing kind of theories related to the issues of Papuan agitation has been explained in clear sequences.

`Markedness' is an epiphenomenon of random phonetically grounded sound change

The concept of `markedness' has been influential in phonology for almost a century, but a recent movement in the field has argued that phonological theories do not need to make reference to the concept; instead, if it is meaningful at all, markedness should be thought of as emergent. In this paper, we propose a simple mathematical model based on the principles of Evolutionary Phonology (EP; Blevins 2004) to explore how a theory without markedness can replicate some of the insights of the markedness-based worldview. We see that markedness can be treated as an epiphenomenon of random, phonetically grounded sound change.

Recent movement of oil prices and future scenarios

The recent movement of oil prices has brought many forecasts about what is coming in the near future. This is natural since the plunge in prices has been dramatic after 2014 and oil is an essential source of energy worldwide. This paper examines the probabilities of spot price scenarios. We model prices through stochastic processes focusing on the Schwartz-Smith model. The calibration is based on the term structure of future prices. Since the conditional distribution is log-normal we define the probability of a certain value of the spot price in a given time horizon. We found that the recovery of crude oil prices will be slow in the next four years. Moreover, the scenario of prices under US$ 20/barrel has the same probability as being greater than US$ 50/barrel. The methodology has many applications, mainly for government planning and for oil companies in their capital budget decisions.
