Widespread concerns about the long-term fiscal gap in Social Security have prompted various proposals for structural reform, with individual accounts as the centerpiece. Carving out individual accounts from the existing system would shift significant risks and responsibilities to individual workers. A parallel development has already occurred in the area of private pensions. Experience with 401 plans indicates that many workers will have difficulty making prudent decisions concerning investment and withdrawal of funds. Moreover, in implementing any system of voluntary individual accounts, (...) it will be important to design default settings that provide appropriate guidance for workers with heterogeneous levels of financial sophistication and risk tolerance. The central goal of Social Security reform should be to close the fiscal gap in a way that preserves rather than undermines the existing system of mandatory defined benefits for all workers.

Most psychological literature on gaslighting focuses on it as a dyadic phenomenon occurring primarily in marriage and family relationships. In my analysis, I will extend recent fruitful philosophical engagement with gaslighting by arguing that gaslighting, particularly gaslighting that occurs in more public spaces like the workplace, relies upon external reinforcement for its success. I will ground this study in an analysis of the film Gaslight, for which the phenomenon is named, and in the course of the analysis will focus on (...) a paradox of this kind of gaslighting: it wreaks significant epistemic and moral damages largely through small, often invisible actions that have power through their accumulation and reinforcement.

This dissertation is an attempt to loosen what I see as a chokehold by which two paramount assumptions constrict our epistemic endeavors. These Enlightenment assumptions--that we accept or refute ideas as true based on transparently clear and orderly methods and criteria, and that individuals accept or refute truth claims--are still central in epistemology, despite their many critics . Thinking about gossip as an epistemologically productive concept provides us with the means to critique those assumptions, and further attempts to broaden our (...) notion of an epistemological foundation. ;Gossip at first appears to be an unlikely candidate for such a resurrection, mainly because its treatment by academics has been dismissive; this dismissal is in part due to Enlightenment conceptions about truth and falsehood. Chapter One surveys the social science literature on gossip and rumor, revealing that social scientists begin with such restrictive definitions of what gossip is that their conclusions amount to little more than tautology. Chapter Two shows that humanists have a slightly different approach to gossip, but with roughly similar results. ;The handful of philosophers who deal directly with gossip or rumor almost as a unit accept uncritically a division between "purposive" conversation and "idle" chatter. To do so, I think, perpetuates a limiting epistemic foundation on a linguistic level. In contrast, I argue in Chapter Three that the very existence of something like gossip proves the inadequacy of the foundationalist myth , and that to attempt to understand and use gossip with foundationalist tools is simply a wrong fit. My understanding of gossip is based on this central fact: we undertake the activity of gossip or rumor-spreading because we are trying to make sense out of something--we need to collect knowledge socially. Gossip originates from dissonance; it acts as a counterweight to more official information, and can't be considered apart from official knowledge. We use gossip and rumor, along with more orthodox sources of information, to formulate our understanding of ourselves and the world around us. The extent to which gossip and rumor are spread is the extent to which the analysis is shared, and not individualized. Gossip is both a genealogical tool and an speculative tool. (shrink)

A striking and unexplained feature of granulomatous inflammation is its anatomical association with the lymphatic system. Accumulating evidence suggests that lymphatic tracks and granulomas may alter the function of each other. The formation of new lymphatics, or lymphangiogenesis, is an adaptive response to tumor formation, infection, and wound healing. Granulomas also may induce lymphangiogenesis which, through a variety of mechanisms, could contribute to disease outcomes in tuberculosis and sarcoidosis. On the other hand, alterations in lymph node function and lymphatic draining (...) may be primary events which attenuate the risk and severity of granulomatous inflammation. This review begins with an introduction of granulomatous inflammation and the lymphatic system. A role of the lymphatic system in tuberculosis and sarcoidosis is then hypothesized. With a focus on lymphangiogenesis in these diseases, and on the potential for this process to promote dissemination, parallels are established with the well‐established role of lymphangiogenesis in tumor biology.

Candrakīrti is known for his commentaries on the major works of Nāgārjuna and Āryadeva. This chapter examines how Candrakīrti uses language and logic to undermine people's confidence in cherished beliefs about a self and point them towards the Buddha's path and its goal the peace of nirvana that transcends the limitations of language and logic. Candrakīrti first sets out his view on the two truths in the Madhyamakāvatāra. He associates both truths with the soteriological goal of Nāgārjuna's path: the peaceful (...) state of nirvana. Madhyamaka teaching amounts to nihilism. Candrakīrti responds that the charge of nihilism is wrong because there is no repudiation of moral actions. Emptiness is also related to the concept of intrinsic nature, and Candrakīrti uses this term in more than one sense. (shrink)

This target article draws together two groups of experimental studies on the control of human movement through peripheral feedback and centrally generated signals of motor commands. First, during natural movement, feedback from muscle, joint, and cutaneous afferents changes; in human subjects these changes have reflex and kinesthetic consequences. Recent psychophysical and microneurographic evidence suggests that joint and even cutaneous afferents may have a proprioceptive role. Second, the role of centrally generated motor commands in the control of normal movements and movements (...) following acute and chronic deafferentation is reviewed. There is increasing evidence that subjects can perceive their motor commands under various conditions, but that this is inadequate for normal movement; deficits in motor performance arise when the reliance on proprioceptive feedback is abolished either experimentally or because of pathology. During natural movement, the CNS appears to have access to functionally useful input from a range of peripheral receptors as well as from internally generated command signals. The unanswered questions that remain suggest a number of avenues for further research. (shrink)

Physicians and medical institutions in the United States are placing increasing emphasis on providing culturally sensitive care for patients, such as implementing a Confucian family-based model of medical decision making when caring for elderly Chinese patients. In this article, I articulate various reasons why deferring to the family is not a guarantee of culturally sensitive care, particularly when family members are first-generation Chinese-Americans. Nonetheless, I offer several suggestions to help physicians, medical institutions, and family members to provide more culturally sensitive (...) care for elderly Chinese patients. (shrink)

Skin pigment pattern formation is a paradigmatic example of pattern formation. In zebrafish, the adult body stripes are generated by coordinated rearrangement of three distinct pigment cell‐types, black melanocytes, shiny iridophores and yellow xanthophores. A stem cell origin of melanocytes and iridophores has been proposed although the potency of those stem cells has remained unclear. Xanthophores, however, seemed to originate predominantly from proliferation of embryonic xanthophores. Now, data from Singh et al. shows that all three cell‐types derive from shared stem (...) cells, and that these cells generate peripheral neural cell‐types too. Furthermore, clonal compositions are best explained by a progressive fate restriction model generating the individual cell‐types. The numbers of adult pigment stem cells associated with the dorsal root ganglia remain low, but progenitor numbers increase significantly during larval development up to metamorphosis, likely via production of partially restricted progenitors on the spinal nerves.

Although prior work on ethical decision-making has examined the direct impact of magnitude of consequences as well as the direct impact of emotions on ethical judgments, the current research examines the interaction of these two constructs. Building on previous research finding disgust to have a varying impact on ethical judgments depending on the specific behavior being evaluated, we investigate how disgust, as well as happiness and sadness, moderates the effect of magnitude of consequences on an individual’s judgments of another person’s (...) unethical behavior. Specifically, we propose and find that because disgust and happiness are both associated with more heuristic-based processing, they both lead to a stronger reliance on the magnitude of consequences when forming ethical judgments. In contrast, because sad and neutral emotional states are associated with more systematic processing, they both result in a weaker reliance on the magnitude of consequences. As such, the effect of magnitude of consequences on judgments of unethical behaviors is stronger when individuals making the judgments are experiencing disgust or happiness versus sadness or a neutral state. This research shows that ethical judgment severity is contingent on individual-level factors, particularly the current emotional state being experienced by the individual, interacting with magnitude of consequences to impact the ethical decision-making process.

In Tudor and Stuart Britain, women writers took active roles in negotiating cultural ideas and systems to gain power by participating in politics through writing, shaping the aesthetics of genre, and fashioning feminine gender, despite constraints on women. Through the lens of cultural studies, the authors explore the ways in which women of this era worked to actually create culture. Articles cover five areas: women, writing, and material culture; women as objects and agents in reproducing culture; women's role in producing (...) gender; popular culture and women's pamphlets; and women's bodies as inscriptions of culture.

Within the realm of nano-, bio-, info- and cogno- (or NBIC) technosciences, the ‘power to change the world’ is often invoked. One could dismiss such formulations as ‘purely rhetorical’, interpret them as rhetorical and self-fulfilling or view them as an adequate depiction of one of the fundamental characteristics of technoscience. In the latter case, a very specific nexus between science and technology, or, the epistemic and the constructionist realm is envisioned. The following paper focuses on this nexus drawing on theoretical (...) conceptions as well as empirical material. It presents an overview of different technoscientific ways to ‘change the world’—via contemplation and representation, intervention and control, engineering, construction and creation. It further argues that the hybrid character of technoscience makes it difficult (if not impossible) to separate knowledge production from real world interventions and challenges current science and technology policy approaches in fundamental ways.

The author interprets idolatry, totemism, sacrilege and taboo through her theory of sexual difference and her study of Eastern spirituality. She argues that the taboo on spirituality in Western culture has cancelled difference, resulting in our current forms of idolatry. Preserving difference, however, would allow the transcendence of the human other to exist. The task of learning to respect difference is central to human spirituality and spiritual progression. The article is a translation of “La transcendance de l’autre” in Autour d’idôlatrie: (...) figures actuelles de pouvoir et de domination, Ed. Bernard Van Meenen, Publications des Facultés Universitaires Saint-Louis, Brussels: 2003. (shrink)

There are growing concerns that increased screen device usage may have a detrimental impact on classroom behaviour and attentional focus. The consequences of screen use on child cognitive functioning have been relatively under-studied, and results remain largely inconsistent. Screen usage may displace the time usually spent asleep. The aim of this study was to examine associations between screen use, behavioural inattention and sustained attention control, and the potential modifying role of sleep. The relations between screen use, behavioural inattention, sustained attention (...) and sleep were investigated in 162 6- to 8-year-old children, using parent-reported daily screen use, the SWAN ADHD behaviour rating scale, The sustained attention to response task and the children’s sleep habits questionnaire. Tablet use was associated with better sustained attention performance but was not associated with classroom behavioural inattention. Shorter sleep duration was associated with poorer behavioural inattention and sustained attention. Sleep quality and duration did not act as mediators between screen usage and behavioural inattention nor sustained attention control. These findings suggest that careful management of the amount of time spent on electronic screen devices could have a beneficial cognitive impact on young children. The results also highlight the critical role of sleep in enhancing both behavioural attention and sustained attention, which are essential for supporting cognitive development and learning. (shrink)

In matters of governance, is believing subject to ethical standards? If so, what are the criteria how relevant are they in our personal and political culture today? The really important matters in politics and governance necessitate a confidence that our beliefs will lead dependably to predictable and verifiable outcomes. Accordingly, it is unethical to hold a belief that is founded on insufficient evidence or based on hearsay or blind acceptance. In this paper, we demonstrate that the pragmatist concept of truth (...) best meets this standard for ethically held belief in matters of politics and governance. Currently, these standards are abused by the gaslighting and distortion characteristics of the often social media driven ‘misinformation society’. The legitimacy and trust in our institutions and leadership that is requisite for good governance is challenged thereby, threatening the viability of our republic. (shrink)

The counseling process involves attention, emotional perception, cognitive appraisal, and decision-making. This study aimed to investigate cognitive appraisal and the associated emotional processes when reading short therapists' statements of motivational interviewing (MI). Thirty participants with work injuries were classified into the pre-contemplation (PC,n= 15) or readiness stage of the change group (RD,n= 15). The participants viewed MI congruent (MI-C), MI incongruent (MI-INC), or control phrases during which their electroencephalograms were captured. The results indicated significant Group × Condition effects in the (...) frontally oriented late positive complex (P600/LPC). The P600/LPC's amplitudes were more positive-going in the PC than in the RD group for the MI congruent statements. Within the PC group, the amplitudes of the N400 were significantly correlated (r= 0.607–0.649) with the participants' level of negative affect. Our findings suggest that the brief contents of MI statements alone can elicit late cognitive and emotional appraisal processes beyond semantic processing. (shrink)

Health research increasingly relies on organized collections of health data and biological samples. There are many types of sample and data collections that are used for health research, though these are collected for many purposes, not all of which are health-related. These collections exist under different jurisdictional and regulatory arrangements and include: 1) Population biobanks, cohort studies, and genome databases 2) Clinical and public health data 3) Direct-to-consumer genetic testing 4) Social media 5) Fitness trackers, health apps, and biometric data (...) sensors Population biobanks, cohort studies, and genome databases Clinical and public health data Direct-to-consumer genetic testing Social media Fitness trackers, health apps, and biometric data sensors Ethical, legal, and social challenges of such collections are well recognized, but there has been limited attention to the broader societal implications of the existence of these collections. Although health research conducted using these collections is broadly recognized as beneficent, secondary uses of these data and samples may be controversial. We examine both documented and hypothetical scenarios of secondary uses of health data and samples. In particular, we focus on the use of health data for purposes of: Forensic investigations Civil lawsuits Identification of victims of mass casualty events Denial of entry for border security and immigration Making health resource rationing decisions Facilitating human rights abuses in autocratic regimes Forensic investigations Civil lawsuits Identification of victims of mass casualty events Denial of entry for border security and immigration Making health resource rationing decisions Facilitating human rights abuses in autocratic regimes Current safeguards relating to the use of health data and samples include research ethics oversight and privacy laws. These safeguards have a strong focus on informed consent and anonymization, which are aimed at the protection of the individual research subject. They are not intended to address broader societal implications of health data and sample collections. As such, existing arrangements are insufficient to protect against subversion of health databases for non-sanctioned secondary uses, or to provide guidance for reasonable but controversial secondary uses. We are concerned that existing debate in the scholarly literature and beyond has not sufficiently recognized the secondary data uses we outline in this paper. Our main purpose, therefore, is to raise awareness of the potential for unforeseen and unintended consequences, in particular negative consequences, of the increased availability and development of health data collections for research, by providing a comprehensive review of documented and hypothetical non-health research uses of such data.

Learning to map words onto their referents is difficult, because there are multiple possibilities for forming these mappings. Cross-situational learning studies have shown that word-object mappings can be learned across multiple situations, as can verbs when presented in a syntactic context. However, these previous studies have presented either nouns or verbs in ambiguous contexts and thus bypass much of the complexity of multiple grammatical categories in speech. We show that noun word learning in adults is robust when objects are moving, (...) and that verbs can also be learned from similar scenes without additional syntactic information. Furthermore, we show that both nouns and verbs can be acquired simultaneously, thus resolving category-level as well as individual word-level ambiguity. However, nouns were learned more quickly than verbs, and we discuss this in light of previous studies investigating the noun advantage in word learning. (shrink)
