The book has been making the case that perspectival content is necessary for the explanation of much of human activity, and that the best approach to tense is to think in terms of interperspectival contents. It has already covered a number of metaphysical worries about tense and perspectival contents (McTaggart’s argument, for example) but there are two additional worries that need to be addressed. The first has to do with the problem of truth-makers. The second has to do with the kinds of contents that are metaphysically admissible. It is argued that metaphysical concerns about truth-makers and Humean supervenience do not undermine the positing of interperspectival contents. Such contents are part and parcel of basic low-level descriptions and they do not thwart attempts at naturalization of our accounts of action, emotion, etc.

Abstract ContextHuman activity in wildlands can influence wildlife populations by decreasing or degrading habitat, decreasing survival, or through displacement. For bighorn sheep (Ovis canadensis), some human activities are detrimental and may result in physiological stress, altered activity budgets, or habitat abandonment. From 1979 to 2000, human recreation increased over 300% in areas occupied by desert bighorn sheep (O. c. nelsoni) in south-eastern Utah. Concurrently, the population of desert bighorn sheep occupying the Potash Bighorn Sheep Management Unit of south-eastern Utah was in steep decline. AimsWe investigated behavioural responses of desert bighorn sheep to different levels of human activity in this area from 2002 to 2003. MethodsWe divided the study population into two areas on the basis of the level of human use, i.e. low and high. We observed desert bighorn sheep at seven sites within these areas, including three with a high level of human use and four areas of a low level of human use. Key resultsDesert bighorn sheep spent significantly less time grazing and more time vigilant in areas of a high level of human use than in areas of a low level of human use. ConclusionsHuman recreational use of desert bighorn sheep habitat has the potential to negatively affect foraging by desert bighorn sheep. ImplicationsWe raise a cautionary flag because recreational use in bighorn sheep habitat near Moab, Utah, continues to increase and bighorn numbers continue to decline. When managers consider proposals to increase areas or trails for human recreation, they should incorporate ways to minimise impacts and reduce stressors to bighorn sheep.

Language and life are inter-related. The scope of language is widened with the widening scope of human activity. Today there is no activity, which does not find its expression in terms of language. Listening and reading are passive or receptive skills and speaking and writing are active or productive skills. The paper is an attempt to find to identify the receptive skills in English among B.Ed trainees. The investigator adopted the survey method to study receptive skills of B.Ed trainees. The study is based on primary data which is collected from 300 BEd trainees in and around Coimbatore district using simple random sampling technique. The findings reveal that totally 25% of the selected B.Ed. trainees belong to low level of receptive skill, 46.6% of the selected BEd trainees belong to moderate level of receptive skill, 26.6% of the selected BEd trainees belong to high level of receptive skill. Also it is found that there is no significant difference in receptive among the selected B.Ed trainees based on gender and locality.

This paper analyzes the concept of creativity as a component part of the research activity, both having a universal character, applicable in all spheres of human activity. The creative process is carried out in 4 stages (preparation, incubation, lighting and evaluation), on the realization of which depends if the solution for the researched problem will be found. In the learning process, the student manifests himself at the level of productive creativity (one of the four types of creativity), which involves a process of creating useful things based on the skills and abilities acquired, although these things can be achieved at a low level of originality. The research conducted by students refers to new knowledge, experiences, life lessons, obtained independently, being argued theoretically (with the help of scientific studies) and practically (in the laboratory called "literary work"). Within the research activity, the 3 dimensions of the creative personality are developed: imagination, judgment, taste.

We investigated the change of tryptophan-niacin metabolism in rats with puromycin aminonucleoside PAN-induced nephrosis, the mechanisms responsible for their change of urinary excretion of nicotinamide and its metabolites, and the role of the kidney in tryptophan-niacin conversion. PAN-treated rats were intraperitoneally injected once with a 1.0% (w/v) solution of PAN at a dose of 100 mg/kg body weight. The collection of 24-hour urine was conducted 8 days after PAN injection. Daily urinary excretion of nicotinamide and its metabolites, liver and blood NAD, and key enzyme activities of tryptophan-niacin metabolism were determined. In PAN-treated rats, the sum of urinary excretion of nicotinamide and its metabolites was significantly lower compared with controls. The kidneyα-amino-β-carboxymuconate-ε-semialdehyde decarboxylase (ACMSD) activity in the PAN-treated group was significantly decreased by 50%, compared with the control group. Although kidney ACMSD activity was reduced, the conversion of tryptophan to niacin tended to be lower in the PAN-treated rats. A decrease in urinary excretion of niacin and the conversion of tryptophan to niacin in nephrotic rats may contribute to a low level of blood tryptophan. The role of kidney ACMSD activity may be minimal concerning tryptophan-niacin conversion under this experimental condition.
