In March, 2004, the rural northern California county of Mendocino voted to ban the propagation of all genetically modified organisms (GMOs). This county was the first, and only, U.S. region to adopt such a ban despite widespread activism against biotechnology. Using a civic agriculture perspective, this article explores how local actors in this small county were able to take on the agri-biotechnology industry. I argue that by localizing the issue, the citizens of Mendocino County were able to ignite a highly (...) effective, decentralized and grassroots social movement against which powerful, and well-funded, pro-biotechnology entities were unable to compete. The social problem of biotechnology was embedded in issues of mass concern to Mendocino County residents, such as democracy, equity, distribution of power, and corporate control over local life. The campaign was an arena for “local problem-solving activities organized around food and agriculture” (Lyson 2004, p. 103). However, though localizing this issue was key for generating a successful ban against the propagation of GMOs at the county level, the local orientation of the No to GMOs movement created a barrier for scaling-up and transferring this success to the wider anti-biotechnology movement.

Horizontal transfer (HT) is the transmission of genetic material between non‐mating species, a phenomenon thought to occur rarely in multicellular eukaryotes. However, many transposable elements (TEs) are not only capable of HT, but have frequently jumped between widely divergent species. Here we review and integrate reported cases of HT in retrotransposons of the BovB family, and DNA transposons, over a broad range of animals spanning all continents. Our conclusions challenge the paradigm that HT in vertebrates is restricted to infective long (...) terminal repeat (LTR) retrotransposons or retroviruses. This raises the possibility that other non‐LTR retrotransposons, such as L1 or CR1 elements, believed to be only vertically transmitted, can horizontally transfer between species. Growing evidence indicates that the process of HT is much more general across different TEs and species than previously believed, and that it likely shapes eukaryotic genomes and catalyses genome evolution.

Lévy's Upward Theorem says that the conditional expectation of an integrable random variable converges with probability one to its true value with increasing information. In this paper, we use methods from effective probability theory to characterise the probability one set along which convergence to the truth occurs, and the rate at which the convergence occurs. We work within the setting of computable probability measures defined on computable Polish spaces and introduce a new general theory of effective disintegrations. We use this (...) machinery to prove our main results, which (1) identify the points along which certain classes of effective random variables converge to the truth in terms of certain classes of algorithmically random points, and which further (2) identify when computable rates of convergence exist. Our convergence results significantly generalize earlier results within a unifying novel abstract framework, and there are no precursors of our results on computable rates of convergence. Finally, we make a case for the importance of our work for the foundations of Bayesian probability theory. (shrink)

Activists’ investigations of animal cruelty expose the public to suffering that they may otherwise be unaware of, via an increasingly broad-ranging media. This may result in ethical dilemmas and a wide range of emotions and reactions. Our hypothesis was that media broadcasts of cruelty to cattle in Indonesian abattoirs would result in an emotional response by the public that would drive their actions towards live animal export. A survey of the public in Australia was undertaken to investigate their reactions and (...) responses to. The most common immediate reaction was feeling pity for the cattle. Women were more likely than men to feel sad or angry. Most people discussed the media coverage with others afterwards but fewer than 10 % contacted politicians or wrote to newspapers. We conclude that the public were emotionally affected by the media coverage of cruelty to cattle but that this did not translate into significant behavioral change. We recommend that future broadcasts of animal cruelty should advise the public of contact details for counseling and that mental health support contacts, and information should be included on the websites of animal advocacy groups to acknowledge the disturbing effect animal cruelty exposes can have on the public.

Undercover filming is a method commonly used by animal activist groups to expose animal cruelty and it is important to consider the effects of publically releasing video footage of cruel practices on the viewers’ mental health. Previously, we reported that members of the Australian public were emotionally distressed soon after viewing media broadcasts of cruelty to Australian cattle exported for slaughter in Indonesia in 2011. To explore if there were any long term impacts from exposure to media on this issue, (...) a self-selecting group of 15 people who were exposed to a documentary exposé of the cruelty were re-interviewed 12 months later. Nearly all recalled their strong initial reaction to the footage. Approximately one half of the respondents who initially had had a strong emotional reaction to the footage reported negative reactions that were still strong even after this period of time. They reported potential triggers for these feelings. Of the rest, some managed to internalise their feelings. Approximately one half of respondents were unaware of continued live export exposés, suggesting less prominent media coverage. Despite the aversion and repulsion reported after viewing the initial coverage, most respondents said they would choose to watch another broadcast of animal cruelty and nearly all supported undercover investigations as a means of revealing cruelty to animals. We conclude that many people viewing footage of cruelty to animals will have long term memory of this, but that they would prefer to be informed about the issues and not be protected from them.

Although very young children have unprecedented access to touchscreen devices, there is limited research on how successfully they operate these devices for play and learning. For infants and toddlers, whose cognitive, fine motor, and executive functions are immature, several basic questions are significant: Can they operate a tablet purposefully to achieve a goal? Can they acquire operating skills and learn new information from commercially available apps? Do individual differences in executive functioning predict success in using and learning from the apps? (...) Accordingly, 31 2-year-olds were compared with 29 3-year-olds using two commercially available apps with different task and skill requirements: a shape matching app performed across 3 days, and a storybook app with performance compared to that on a matched paper storybook. Children also completed the Minnesota Executive Functioning Scale. An adult provided minimal scaffolding throughout. The results showed: toddlers could provide simple goal-directed touch gestures and the manual interactions needed to operate the tablet after controlling for prior experience with shape matching, toddlers’ increased success and efficiency, made fewer errors, decreased completion times, and required less scaffolding across trials, they recognized more story content from the e-book and were less distracted than from the paper book, executive functioning contributed unique variance to the outcome measures on both apps, and 3-year-olds outperformed 2-year-olds on all measures. The results are discussed in terms of the potential of interactive devices to support toddlers’ learning. (shrink)

The central insight of Darwin's Origin of Species is that evolution is an ecological phenomenon, arising from the activities of organisms in the 'struggle for life'. By contrast, the Modern Synthesis theory of evolution, which rose to prominence in the twentieth century, presents evolution as a fundamentally molecular phenomenon, occurring in populations of sub-organismal entities - genes. After nearly a century of success, the Modern Synthesis theory is now being challenged by empirical advances in the study of organismal development and (...) inheritance. In this important study, D. M. Walsh shows that the principal defect of the Modern Synthesis resides in its rejection of Darwin's organismal perspective, and argues for 'situated Darwinism': an alternative, organism-centred conception of evolution that prioritises organisms as adaptive agents. His book will be of interest to scholars and advanced students of evolutionary biology and the philosophy of biology. (shrink)

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: denis.walsh@utoronto.ca.

The most compelling extant accounts of explanation casts all explanations as causal. Yet there are sciences, theoretical population biology in particular, that explain their phenomena by appeal to statistical, non-causal properties of ensembles. I develop a generalised account of explanation. An explanation serves two functions: metaphysical and cognitive. The metaphysical function is discharged by identifying a counterfactually robust invariance relation between explanans event and explanandum. The cognitive function is discharged by providing an appropriate description of this relation. I offer examples (...) of explanations from portfolio theory and population genetics that meet this characterisation. In each case the invariance relation holds between a statistical property of an ensemble and a change in structure of the ensemble. In neither case, however, does the statistical property cause the outcome it explains. There are genuine statistical, non-causal scientific explanations. (shrink)

This paper treats a heretofore-unnoticed concept in the history of the philosophical discussion of human freedom, a kind of freedom that is not defined solely in terms of the causal power of the agent. Instead, the exercise of freedom essentially involves the non-occurrence of something. That being free involves the non-occurrence, that is, the absence, of an act may seem counterintuitive. With the exception of those specifically treated in this paper, philosophers tend to think of freedom as intimately involved with (...) volition, the judging or deciding activity of the will that votes in favor of or against a proposed action. However, there are two thinkers who endorse a view where not willing constitutes human freedom. Our analysis focuses on the views of Malebranche and Locke. Both invoke a notion dubbed here as ‘absential suspension.’ On this view, freedom is associated not with the power of volition, but rather with this kind of suspension. (shrink)

The Units of Selection debate is a dispute about the causes of population change. I argue that it is generated by a particular `dynamical'' interpretation of natural selection theory, according to which natural selection causes differential survival and reproduction of individuals and natural selection explanations cite these causes. I argue that the dynamical interpretation is mistaken and offer in outline an alternative, `statistical'' interpretation, according to which natural selection theory is a fancy kind of `bookkeeping''. It explains by citing the (...) statistical structure of a population and not by citing the causes of survival and reproduction. From the perspective of the statistical interpretation there is no substantive Units of Selection issue. (shrink)

While French biologists were turning a cold shoulder to On the Origin of Species in the 1860s, Charles Darwin was earnestly pursuing a professional connection with one French physiologist in particular: Charles Brown-Séquard. Darwin had been closely following Brown-Séquard’s startling experiments on guinea pigs, which demonstrated that experimentally induced epilepsy could pass from parent to offspring. In Darwin’s mind, Brown-Séquard had produced the most convincing evidence to date that acquired traits could be inherited. Darwin saw opportunities in Brown-Séquard and his (...) work. If Brown-Séquard realized the evolutionary implications of his experiments, and then endorsed the Origin in Paris, Darwin could be well on his way to securing a French audience for his theories. Darwin quickly mobilized his powers of correspondence to make this French connection, but Brown-Séquard received Darwin’s advances with caution. A connection with Darwin could be useful in London and America, where he was increasingly spending time, but to publicly support Darwin would be professionally damaging back home in Paris. This paper examines the dance of letters between Darwin and Brown-Séquard, the politics of citation, and the delicacy of sustaining a transnational biological career between France and Britain in the 1860s. This paper casts a new perspective on an old debate in the history of biology. I show that from within the “heavy cloud” of anti-evolutionary thought in France, there existed a live wire between Brown-Séquard and Darwin. I argue that British evolutionary theory in the age of Darwin was built, in part, with French participation. (shrink)

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment ( n = 36) compared reason - action sequences to cause - effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: (...) they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment ( n = 214) and the third experiment ( n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons. (shrink)

Wide content and individualist approaches to the individuation of thoughts appear to be incompatible; I think they are not. I propose a criterion for the classification of thoughts which captures both. Thoughts, I claim, should be individuated by their teleological functions. Where teleological function is construed in the standard way - according to the aetiological theory - individuating thoughts by their function cannot produce a classification which is both individualistic and consistent with the principle that sameness of wide content is (...) sufficient for sameness of psychological state. There is, however, an alternative approach to function, the relational theory, which is preferable on independent grounds. A taxonomy of thoughts based on these functions reconciles wide content with individualism. One consequence of individuating thoughts in this way is that intentional content is context sensitive. I discuss some of the implications of context sensitive content. (shrink)

In this study we use dual process theory of self-regulation to develop a framework that outlines the mediating and moderating mechanisms explaining the relationship between leader emotional exhaustion and leadership style (transformational leadership and abusive supervision). Using Glomb et al.’s (2011) framework, we identify empathy and negative emotion as mediators that are of particular importance for leaders. In addition, we propose that leader mindfulness moderates these processes to improve leadership style. Using a time-lagged survey of leaders (N = 505) we (...) found that leader empathy and negative emotion mediated the relationships between emotional exhaustion and leadership style. Furthermore, we found that leader mindfulness significantly moderated the indirect effect of leader emotional exhaustion on leadership style through negative emotion. However, leader mindfulness did not moderate the relationship between emotional exhaustion and empathy. Theoretical and practical implications are discussed. (shrink)

Philosophical writing is challenging for students new to philosophy. Many philosophy classes are populated, for the most part, by students who have never taken philosophy before. While many institutions offer general writing support services, these services tend to be most beneficial for helping to identify problems with style and grammar. They are not equipped to help students with the particular challenges that come with writing philosophy for the first time. We implemented the “Home Base” Mentoring Program in two introductory level (...) philosophy courses to target the specific challenges that novice learners have when learning how to write philosophy. Through the program, students had access to writing mentors who were undergraduate senior philosophy majors. Based on surveys given to the students who have participated in this program, we found that the program boosted student confidence in writing and also worked to develop a welcoming, judgment-free, and encouraging environment in the philosophy department more generally.

There are three common objections that any broadly Aristotelian virtue theorist must face, insofar as he or she holds that acts must be performed from a firm and stable disposition in order to express virtue, and that virtue is in some way a praiseworthy fulfillment of human potential. Each of these objections accuses the virtuous person of not fully exercising his or her rationality and freedom, and thus of being somehow less than fully human.

Irrelevant emotional stimuli often capture attention, disrupting ongoing cognitive processes. In two experiments, we examined whether availability of rewards can prevent...

There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power. (shrink)

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both. The function of a trait is the way it contributes to fitness and fitness can only be determined relative to a selective regime. Therefore, the function of a trait can only be specified relative to a selective regime. Apart (...) from its desirable pluralism, only this view of relational function can support the function/accident and function/malfunction distinctions commonly thought to be part of the concept of function. Furthermore, only relational function correctly characterizes the explanatory consequences of function attributions in evolutionary biology. (shrink)

There are two general approaches to characterising biological functions. One originates with Cummins. According to this approach, the function of a part of a system is just its causal contribution to some specified activity of the system. Call this the ‘C-function’ concept. The other approach ties the function of a trait to some aspect of its evolutionary significance. Call this the ‘E-function’ concept. According to the latter view, a trait's function is determined by the forces of natural selection. The C-function (...) and E-function concepts are clearly quite different, but there is an important relation between them which heretofore has gone unnoticed. The purpose of this paper is to outline that relation.This is not the first paper to discuss the relation of C-function and E-function. Previous attempts all follow either one of two strategies. The first proposes that the two concepts are ‘unified.’ The other proposes that they are radically distinct and apply to wholly different fields within biology. (shrink)

Singles are an understudied yet growing segment of the adult population. The current study aims to expand the lens of relationship science by examining the well-being of unpartnered, single adults using latent profile analysis. We recruited singles closely matched to the United States census for an exploratory cross-sectional survey using five variables that strongly predict well-being. All five variables significantly predicted life satisfaction for the full sample. Latent profile analyses detected 10 groups of singles. Half of the profiles were happy (...) and half of the profiles were unhappy. Each profile had its own unique patterns relating to personal relationships, self-esteem, and personality traits. The happiest profile had the best relationships, self-esteem, and personality, while the unhappiest profile had the worst relationships, self-esteem, and personality. The profiles in between these two extremes had more nuanced patterns. For example, one relatively happy profile in the middle had high friendship satisfaction but low family satisfaction, while an adjacent profile showed the opposite pattern. Overall, singles who had positive relationships—both with themselves and others—were happiest. (shrink)

When I say ‘pain’, it is clearly a singular phenomenon. Yet if I ask for an example, you can provide many varying instances that confound the idea of its singularity. How can a pinprick be of the same thing as depression or grief? This study maintains the singularity of pain by exploring the process and structure of its experience to account for its variance and its subjectivity. Heidegger’s Being and Time provides the pathway to achieving this, where we comprehend how (...) pain’s myriad manifestations, and their inherent subjectivity, relate to our way of Being – the meaningful horizon through which we encounter pain. The study comes to tie the process of encountering pain with a structure that suffering provides, which explains both the variance and the subjectivity of the pain experience. This can then be mapped onto individual experiences of a singular phenomenon to understand how they arose and what has conditioned them. (shrink)

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

I argue that recent advances in developmental biology demonstrate the inadequacy of suborganismal mechanism. The category of the organism, construed as a ’natural purpose’ should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon (...) and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

The Quietist affair at the end of the seventeenth century has much to teach us about theories of the will in the period. Although Bossuet and Fénelon are the names most famously associated with the debate over the Quietist conception of pure love, Malebranche and his erstwhile disciple Lamy were the ones who debated the deep philosophical issues involved. This paper sets the historical context of the debate, discusses the positions as well as the arguments for and against them, and (...) opens up investigation of important material that is all but ignored in the English literature and only incompletely addressed in the French.

Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as “automatic writing” whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant (...) reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.
