Personal and sub-personal: a defence of Dennett's early distinction

Since 1969, when Dennett introduced a distinction between personal and sub‐personal levels of explanation, many philosophers have used ‘sub‐personal’ very loosely, and Dennett himself has abandoned a view of the personal level as genuinely autonomous. I recommend a position in which Dennett's original distinction is crucial, by arguing that the phenomenon called mental causation is on view only at the properly personal level. If one retains the commit‐’ ments incurred by Dennett's early distinction, then one has a satisfactory anti‐physicalistic, anti‐dualist philosophy of mind. It neither interferes with the projects of sub‐personal psychology, nor encourages ; instrumentalism at the personal level. People lose sight of Dennett’s personal/sub-personal distinction because they free it from its philosophical moorings. A distinction that serves a philosophical purpose is typically rooted in doctrine; it cannot be lifted out of context and continue to do its work. So I shall start from Dennett’s distinction as I read it in its original context. And when I speak of ‘the distinction’, I mean to point not only towards the terms that Dennett first used to define it but also towards the philosophical setting within which its work was cut out

Demographic and phenotypic reactions to climate by western North American woodrats (Neotoma spp.)

Species can react or adapt to climate in many ways, which can be studied through both space and time and using a number of perspectives and tools. North American woodrats (Neotoma spp.) are widespread across a variety of climates and also represented extensively in late Quaternary deposits, making them an excellent system for studying the effects of climate in a variety of ways. My dissertation includes three chapters that employ several methods and perspectives to explore how Neotoma spp. have reacted and adapted to climate. In my first chapter, I use a statistical phylogeographic approach to determine the accuracy of quantitative demographic signals derived from common proxies of Pleistocene-Holocene population history, finding that these proxies accurately reflect the most recent population expansion but may fail to capture other demographic events for a variety of reasons. In my second chapter, I use ancient DNA to determine the pattern and pace of Neotoma spp. turnover along a 33,000-year elevational transect, finding that the turnover was abrupt, final, and reflects the role of species interactions in reaction to climate. In my third chapter, I use geometric morphometrics to assess the developmental causes and morphometric consequences of adherence to ecogeographic rules, finding that N. cinerea are smaller in warmer and less productive climates, that the size differences among climates are established prior to weaning, and that smaller-bodied groups avoid pedomorphism through a break in the size-shape (allometric) relationship. Though these chapters do not build explicitly as a single narrative, they address complementary pieces of the very large question of species reactions to climate, and provide a step towards a more complete and integrated view of the myriad effects of climate through space and time

Do actions occur inside the body?

The paper offers a critical examination of Jennifer Hornsby's view that actions are internal to the body. It focuses on three of Hornsby's central claims: (P) many actions are bodily movements (in a special sense of the word “movement”) (Q) all actions are tryings; and (R) all actions occur inside the body. It is argued, contra Hornsby, that we may accept (P) and (Q) without accepting also the implausible (R). Two arguments are first offered in favour of the thesis (Contrary-R): that no actions occur inside the body. Three of Hornsby's arguments in favour of R are then examined. It is argued that we need to make a distinction between the causes and the causings of bodily movements (in the ordinary sense of the word “movement”) and that actions ought to be identified with the latter rather than the former. This distinction is then used to show how Hornsby's arguments for (R) may be resisted

Digital Technological Innovation and the International Political Economy

This chapter explores the main digital technological innovations currently associated with the Fourth Industrial Revolution - Artificial Intelligence (AI), Blockchain, and the Internet of Things (IoT) - and their effects on the international political economy. It reviews some of their main benefits and challenges to established structures of the global economy, such as international trade and production, or the monetary and financial system. The chapter highlights that the complex coupling, interdependencies and pervasiveness of these digital innovations disrupts the practice of international political economy on three dimensions: the established institutions that structure the international political economy; the distribution of authority between state and non-state actors; and the distribution of resources between and within developed and developing states

Has recent climate change caused a genetic bottleneck in a Sierra Nevada population of the bushy-tailed woodrat?

Many montane species respond to climate change by shifting their range upslope as temperatures at lower elevations increase. An elevation range shift causes a range contraction that may result in a population bottleneck. Joseph Grinnell surveyed the fauna along the Yosemite transect from 1914 to 1920. In 2003 Craig Moritz and his colleagues began to resurvey the Yosemite transect to assess the faunal change during a century of climate change. The bushy-tailed woodrat suffered severe range contraction and population bottleneck between the two surveys. I will use evolutionary models to determine if the population has suffered a genetic bottleneck

The linear tearing instability in three dimensional, toroidal gyrokinetic simulations

Linear gyro-kinetic simulations of the classical tearing mode in three-dimensional toroidal geometry were performed using the global gyro kinetic turbulence code, GKW . The results were benchmarked against a cylindrical ideal MHD and analytical theory calculations. The stability, growth rate and frequency of the mode were investigated by varying the current profile, collisionality and the pressure gradients. Both collision-less and semi-collisional tearing modes were found with a smooth transition between the two. A residual, finite, rotation frequency of the mode even in the absense of a pressure gradient is observed which is attributed to toroidal finite Larmor-radius effects. When a pressure gradient is present at low collisionality, the mode rotates at the expected electron diamagnetic frequency. However the island rotation reverses direction at high collisionality. The growth rate is found to follow a $\eta^{1/7}$ scaling with collisional resistivity in the semi-collisional regime, closely following the semi-collisional scaling found by Fitzpatrick. The stability of the mode closely follows the stability using resistive MHD theory, however a modification due to toroidal coupling and pressure effects is seen

Nonhuman Primate Induced Pluripotent Stem Cells in Regenerative Medicine

Among the various species from which induced pluripotent stem cells have been derived, nonhuman primates (NHPs) have a unique role as preclinical models. Their relatedness to humans and similar physiology, including central nervous system, make them ideal for translational studies. We review here the progress made in deriving and characterizing iPS cell lines from different NHP species. We focus on iPS cell lines from the marmoset, a small NHP in which several human disease states can be modeled. The marmoset can serve as a model for the implementation of patient-specific autologous cell therapy in regenerative medicine

The acute effects of whole body vibration on isometric mid-thigh pull performance

The purpose of the present investigation was to examine the acute effects of whole body vibration (WBV) on isometric mid-thigh pull force–time curve (FTC) characteristics. Eleven recreationally trained subjects were randomly assigned to three treatment conditions: sham no vibration protocol (T1), vibration protocol 30 Hz 2–4 mm amplitude (T2), and vibration protocol 30 Hz 2–4 mm (T3). After completing a standardized warm-up, the subject stood on a vibration platform with the knee at a 120° angle and performed one of the three interventions. Each treatment condition required the subject to stand on the platform for thirty-second treatments, each separated by thirty seconds of recovery. Five minutes after the completion of the treatment conditions, the subjects performed the isometric mid-thigh pull. All FTCs were analyzed with standardized procedures for peak force (PF) and peak rate of force development (PRFD). A 1 × 3 repeated measures analysis of variance (ANOVA) was used to compare the three treatments. Additionally, coefficients of variance (CV), as well as intraclass and interclass correlations, were performed. There were no significant differences (p \u3e 0.05) for any of the FTC analyses performed in this investigation. The CV and the 95% confidence interval (CI) indicate that the WBV protocol resulted in trivial changes in PF and beneficial changes in PRFD. A 30 Hz 2–4 mm amplitude WBV does not result in a significant increase in isometric mid-thigh pull performance

Arkansas Cooperative Beef Bull Performance Test 1991

Performance testing of beef bulls was initiated to improve productivity of Arkansas beef cattle through breeding. This cooperative testing program provides cattlemen with reliable information for identifying animals with superior breeding value for the traits of production measured in the test. By using the information as a basis for herd sire selection, a breeder can greatly increase the chances of obtaining a bull that will sire rapid-gaining, more efficient, highquality calves. Such calves can increase profits for both the breeder and the feeder. This testing program provides information that is useful to financial institutes in arranging their lending programs and to companies in developing their educational, promotional and marketing programs
