Non-factive Understanding: A Statement and Defense

In epistemology and philosophy of science, there has been substantial debate about truth’s relation to understanding. “Non-factivists” hold that radical departures from the truth are not always barriers to understanding; “quasi-factivists” demur. The most discussed example concerns scientists’ use of idealizations in certain derivations of the ideal gas law from statistical mechanics. Yet, these discussions have suffered from confusions about the relevant science, as well as conceptual confusions. Addressing this example, we shall argue that the ideal gas law is best interpreted as favoring non-factivism about understanding, but only after delving a bit deeper into the statistical mechanics that has informed these arguments and stating more precisely what non-factivism entails. Along the way, we indicate where earlier discussions have gone astray, and highlight how a naturalistic approach furnishes more nuanced normative theses about the interaction of rationality, understanding, and epistemic value

The influence of poverty on children's school experiences : pupils' perspectives

This study examined the potential influence of policies and practices on the ability of children from low-income families to participate fully in the school day. Pupils from six schools participated in 71 focus groups and revealed a range of barriers affecting their school experience: transport costs and limited support; clothing costs, stigma and enforcement of school dress codes; material barriers to learning at school and home; concerns about free school meals; missing out on school trips, clubs and events. Findings on school uniform were an important catalyst towards a recent policy change in Scotland in increasing the school clothing grant

Caustic Leaching of Sludges from Selected Hanford Tanks

The objective of this project was to measure the caustic dissolution behavior of sludge components from selected Hanford waste tank sludge samples under different conditions. The dissolution of aluminum, chromium, and other constituents of actual sludge samples in aqueous sodium hydroxide solution was evaluated using various values of temperature, sodium hydroxide concentration, volume of caustic solution per unit mass of sludge (liquid:solids ratio), and leaching time

Modern Model of Competences of Personal Agents as Increase Factor of Clients’ Subjective Well-being

The model of competences of personal agents is developed in the article. The model allows raising the level of subjective well-being of clients and promotes the growth of main indicators characterizing productivity of personal selling. The author designates a new group of stakeholders with which the company has to develop relationship for realization of a social orientation. Relationship marketing is defined taking into account the priority of its broad treatments and orientation on developing relationships with various groups of people. The concept ‘personal agent’ is entered into the theory of marketing. This concept reflects the activity of the seller in modern conditions more precisely. The definition of personal selling is given. Novelty of the author's formulation of this definition is that the personal agents have to own skillfully technologies of sales for achieving their purpose. It is proved that the main objective of personal selling in the context of relationship marketing is not sale of goods, but development of relationship between clients and personal agents (company). The author proves the importance of application of psychological theories and offers the method of creation of a psychological portrait of clients on the basis of classification of standard psychological characteristics. The behavioural indicators characterizing demonstration of all main competences of personal agents are revealed and presented

The antibody response to Plasmodium falciparum Merozoite Surface Protein 4: comparative assessment of specificity and growth inhibitory antibody activity to infection-acquired and immunization-induced epitopes

<p>Abstract</p> <p>Background</p> <p>Malaria remains a global public health challenge. It is widely believed that an effective vaccine against malaria will need to incorporate multiple antigens from the various stages of the parasite's complex life cycle. <it>Plasmodium falciparum </it>Merozoite Surface Protein 4 (MSP4) is a vaccine candidate that has been selected for development for inclusion in an asexual stage subunit vaccine against malaria.</p> <p>Methods</p> <p>Nine monoclonal antibodies (Mabs) were produced against <it>Escherichia coli</it>-expressed recombinant MSP4 protein and characterized. These Mabs were used to develop an MSP4-specific competition ELISA to test the binding specificity of antibodies present in sera from naturally <it>P. falciparum</it>-infected individuals from a malaria endemic region of Vietnam. The Mabs were also tested for their capacity to induce <it>P. falciparum </it>growth inhibition <it>in vitro </it>and compared against polyclonal rabbit serum raised against recombinant MSP4</p> <p>Results</p> <p>All Mabs reacted with native parasite protein and collectively recognized at least six epitopes. Four of these Mabs recognize reduction-sensitive epitopes within the epidermal growth factor-like domain found near the C-terminus of MSP4. These sera were shown to contain antibodies capable of inhibiting the binding of the six Mabs indicating infection-acquired responses to the six different epitopes of MSP4. All of the six epitopes were readily recognized by human immune sera. Competition ELISA titres varied from 20 to 640, reflecting heterogeneity in the intensity of the humoral response against the protein among different individuals. The IgG responses during acute and convalescent phases of infection were higher to epitopes in the central region than to other parts of MSP4. Immunization with full length MSP4 in Freund's adjuvant induced rabbit polyclonal antisera able to inhibit parasite growth <it>in vitro </it>in a manner proportionate to the antibody titre. By contrast, polyclonal antisera raised to individual recombinant fragments rMSP4A, rMSP4B, rMSP4C and rMSP4D gave negligible inhibition. Similarly, murine Mabs alone or in combination did not inhibit parasite growth.</p> <p>Conclusions</p> <p>The panel of MSP4-specific Mabs produced were found to recognize six distinct epitopes that are also targeted by human antibodies during natural malaria infection. Antibodies directed to more than three epitope regions spread across MSP4 are likely to be required for <it>P. falciparum </it>growth inhibition <it>in vitro</it>.</p

A stereotype threat account of boys' academic underachievement

Three studies examined the role of stereotype threat in boys' academic underachievement. Study 1 (children aged 4–10, n = 238) showed that girls from age 4 years and boys from age 7 years believed, and thought adults believed, that boys are academically inferior to girls. Study 2 manipulated stereotype threat, informing children aged 7–8 years (n = 162) that boys tend to do worse than girls at school. This manipulation hindered boys' performance on a reading, writing, and math test, but did not affect girls' performance. Study 3 counteracted stereotype threat, informing children aged 6–9 years (n = 184) that boys and girls were expected to perform similarly. This improved the performance of boys and did not affect that of girls

Spirit, mind and body: the archaeology of monastic healing

Archaeology and material culture are used in this chapter to consider how monastic experience responded to illness, ageing and disability. The approach taken is influenced by the material study of religion, which interrogates how bodies and things engage to construct the sensory experience of religion, and by practice-based approaches in archaeology, which examine the active role of space and material culture in shaping religious agency and embodiment. The archaeology of monastic healing focuses on the full spectrum of healing technologies, from managing the body in order to prevent illness, through to the treatment of the sick and preparation of the corpse for burial
