The Objectivity of Ordinary Life

Metaethics tends to take for granted a bare Democritean world of atoms and the void, and then worry about how the human world that we all know can possibly be related to it or justified in its terms. I draw on Wittgenstein to show how completely upside-down this picture is, and make some moves towards turning it the right way up again. There may be a use for something like the bare-Democritean model in some of the sciences, but the picture has no standing as the basic objective truth about the world; if anything has that standing, it is ordinary life. I conclude with some thoughts about how the notion of bare, “thin” perception of non-evaluative reality feeds a number of philosophical pathologies, such as behaviourism, and show how a “thicker”, more value-laden, understanding of our perceptions of the world can be therapeutic against them

The Disjunctive Conception of Perceiving

John McDowell's conception of perceptual knowledge commits him to the claim that if I perceive that P then I am in a position to know that I perceive that P. In the first part of this essay, I present some reasons to be suspicious of this claim - reasons which derive from a general argument against 'luminosity' - and suggest that McDowell can reject this claim, while holding on to almost all of the rest of his conception of perceptual knowledge, by supplementing his existing disjunctive conception of experience with a new disjunctive conception of perceiving. In the second part of the essay, I present some reasons for thinking that one's justification, in cases of perceptual knowledge, consists not in the fact that one perceives that P but in the fact that one perceives such-and-such. I end by suggesting that the disjunctive conception of perceiving should be understood as a disjunctive conception of perceiving such-and-such

Calculations of Neutron Reflectivity in the eV Energy Range from Mirrors made of Heavy Nuclei with Neutron-Nucleus Resonances

We evaluate the reflectivity of neutron mirrors composed of certain heavy nuclei which possess strong neutron-nucleus resonances in the eV energy range. We show that the reflectivity of such a mirror for some nuclei can in principle be high enough near energies corresponding to compound neutron-nucleus resonances to be of interest for certain scientific applications in non-destructive evaluation of subsurface material composition and in the theory of neutron optics beyond the kinematic limit.Comment: 18 pages, 5 figures, 1 tabl

Testing the performance of the ENRICHD Social Support Instrument in cardiac patients

BACKGROUND: Previous investigations suggest an important role of social support in the outcomes of patients treated for ischemic heart disease. The ENRICHD Social Support Instrument (ESSI) is a 7-item self-report survey that assesses social support. Validity and reliability of the ESSI, however, has not been formally tested in patients undergoing percutaneous coronary intervention (PCI). METHODS: The ESSI, along with the Short Form-36 (SF-36), was sequentially administered to a cohort of 271 patients undergoing PCI. The test-retest reliability was examined with an intra-class correlation coefficient by comparing scores among 174 patients who completed both instruments 5 and 6 months after their procedure. Internal reliability was assessed using Cronbach's alpha at the time of patients' baseline procedure. The concurrent validity of the ESSI was assessed by comparing scores between depressed (MHI-5 score < 44) vs. non-depressed patients. The correlation between the ESSI and the SF-36 Social Functioning sub-scale, an accepted measure of social functioning, was also examined. RESULTS: Test-retest reliability showed no significant differences in mean scores among ESSI questionnaires administered 1 month apart (27.8+/-1.4 vs 27.8+/-1.5, p = 0.98). The intra-class correlation coefficient was 0.94 and Cronbach's alpha was 0.88. Mean ESSI scores were significantly lower among depressed vs. non-depressed patients (24.6+/-1.7 vs 27+/-1.4, p < 0.018) and a positive albeit modest correlation with social functioning was seen (r = 0.19, p = 0.002). CONCLUSION: The ESSI appears to be a valid and reliable measure of social support in patients undergoing treatment for coronary artery disease. It may prove to be a valuable method of controlling for patient variability in outcomes studies where the outcomes are related to patients' social support

Effects of the soil microbiome on the demography of two annual prairie plants

This work is licensed under a Creative Commons Attribution 4.0 International License.1. Both mutualistic and pathogenic soil microbes are known to play important roles in shaping the fitness of plants, likely affecting plants at different life cycle stages. 2. In order to investigate the differential effects of native soil mutualists and pathogens on plant fitness, we compared survival and reproduction of two annual tallgrass prairie plant species (Chamaecrista fasciculata and Coreopsis tinctoria) in a field study using 3 soil inocula treatments containing different compositions of microbes. The soil inocula types included fresh native whole soil taken from a remnant prairie containing both native mutualists and pathogens, soil enhanced with arbuscular mycorrhizal (AM) fungi derived from remnant prairies, and uninoculated controls. 3. For both species, plants inoculated with native prairie AM fungi performed much better than those in uninoculated soil for all parts of the life cycle. Plants in the native whole prairie soil were either generally similar to plants in the uninoculated soil or had slightly higher survival or reproduction. 4. Overall, these results suggest that native prairie AM fungi can have important positive effects on the fitness of early successional plants. As inclusion of prairie AM fungi and pathogens decreased plant fitness relative to prairie AM fungi alone, we expect that native pathogens also can have large effects on fitness of these annuals. Our findings support the use of AM fungi to enhance plant establishment in prairie restorations.National Science Foundation (NSF DEB‐1556664)National Science Foundation (DEB‐1738041)National Science Foundation (OIA 1656006

Green human resource management: a comparative qualitative case study of a United States multinational corporation

This article explores the ways in which a multinational company (MNC) approaches Green Human Resource Management (HRM) in its British, German and Swedish subsidiaries. The authors analyze the similarities and differences in Green HRM approaches in these three European subsidiaries of a US restaurant chain. This enables the comparison of Green HRM practises and behaviors, and considers the factors that influence the subsidiaries in this particular domain. Therefore, this research addresses the current lack of international comparative research in the field of Green HRM. The methodological approach is multi-case study with 50 participants, using semi-structured interviews and focus groups. The results show evidence of pro-active environmental management, reflected through a range of operational and people-centred initiatives across the three European countries. Although there is an overarching commitment to environmental sustainability, the positioning and alignment of the environment and HR function differ amongst the subsidiaries, as does the way in which the subsidiaries choose to engage the workforce in environmental sustainability. The study identified a number of factors which explain the differences in approach including, amongst others, strategic and performance drivers and cultural dimensions, such as relationships with key stakeholders

People with aphasia’s perspectives of the therapeutic alliance during speech-language intervention: A Q methodological approach

Purpose: To identify which elements of the therapeutic alliance are important to people with aphasia (PWA) attending speech-language pathology post-stroke. Method: A Q methodology design was adopted to explore which elements of the therapeutic alliance were valued by PWA. Statements (n = 453) relevant to the research question were extrapolated from the literature and qualitative interviews. A representative sample of statements (n = 38) was identified from the expansive data set. PWA (n = 23) sorted statements hierarchically according to whether they thought the statement was important or unimportant. Completed Q sorts were analysed using a by-person factor analysis. Result: Analysis yielded a five-factor solution, representing five distinct viewpoints: (1) acknowledge me, help me to understand; (2) respect me, listen to me; (3) challenge me, direct me; (4) understand me, laugh with me; and (5) hear me, encourage me. Conclusion: The findings highlight the need for clinicians to adopt a flexible and idiosyncratic approach to therapeutic alliance construction in order to meet the relational needs of a heterogeneous population. This is the first study to use Q methodology with PWA, demonstrating that Q methodology is an effective and viable method for investigating subjectivity in this population
