After school, college or university, adult education in Britain continues in many spheres. The Field Studies Council provides opportunities for a wide scope of amateur and professional naturalists to learn about various aspects of ecology through first hand experience in the field with like-minded people. The FSC is internationally recognized as the pioneer in environmental education and is still at the forefront of ecological thought. Courses are run at a variety of levels on a wide range of subjects. Within our full programme, there should be something for all at home or overseas. 相似文献

It is the year 2025. In a leading teaching hospital, in London, New York, Paris, or Tokyo, a little girl is born. Her parents have elected to try an innovative new service that is being offered there--at a price--to all parents of newborns: whole genome analysis.... 相似文献

It is commonly accepted that thewestern view of humanity's place in nature isdominated by a dualistic opposition between nature andculture. Historically this has arisen fromexternalization of nature in both productive andcognitive practices; instances of such externalizationhave become generalized. I think the dualism can bedecomposed by identifying dominant elements in eachparticular instantiation and showing that their strictseparation evaporates under close scrutiny. The philosophical challenge this perspective presents isto substitute concrete socioecological analysis forfoundational metaphysics. A review of majorinterpretations of the history of the dualism inWestern thought indicates that the legacy is moremultistranded than is usually admitted. Modern scienceis often assumed to lie squarely within the dualism,but this is unfounded. In contrast, science providestools for contextual analysis on how human activitiesand natural processes merge. The dualism thusevaporates in actual research practice. Nevertheless,the foundational metaphysics needs to be challenged,primarily because of its paralyzing effect onenvironmental philosophy. 相似文献

The suprachiasmatic nucleus is the master oscillator controlling circadian rhythms in mammals. Yet extensive temporal restructuring of behavior can occur without participation of the suprachiasmatic nucleus. This raises questions about current thinking about how to cope with jet lag and shift work. 相似文献

The human oral microbiome currently comprises 600-700 taxa, but estimates suggest that overall species numbers may turn out to be higher (~1200). Within the oral cavity, groups of microbial species become arranged into surface-localized communities that vary considerably in composition according to sites of establishment. Factors such as nutrient availability, pH, toxic metabolites, shear forces and host conditions contribute to modelling the structure and activities of these oral microbial communities. With development of more rapid and accurate molecular techniques it has become possible to begin to characterize the genome contents of individual communities. However, understanding the phenotypic interactions between cultivable microorganisms within communities is essential in order to complement the genomic data. This will then enable construction of microbial community interactomes, incorporating genomic and spatial information with functional knowledge of physical and metabolic interplays between the microorganisms. Enlightenment of the changes in genome composition and phenotypic interactions as functions of niche, time and intrusions will help towards developing better means of manipulating communities for host benefit. 相似文献

The Hox complex is an example of a gene cluster created by tandem duplications. Recent findings suggest the Hox complex may be just part of a larger chromosomal assemblage of homeobox-containing genes that existed in the ancestor to all vertebrates. 相似文献

A central and influential idea among researchers of language is that our language faculty is organized according to Fregean compositionality, which states that the meaning of an utterance is a function of the meaning of its parts and of the syntactic rules by which these parts are combined. Since the domain of syntactic rules is the sentence, the implication of this idea is that language interpretation takes place in a two-step fashion. First, the meaning of a sentence is computed. In a second step, the sentence meaning is integrated with information from prior discourse, world knowledge, information about the speaker and semantic information from extra-linguistic domains such as co-speech gestures or the visual world. Here, we present results from recordings of event-related brain potentials that are inconsistent with this classical two-step model of language interpretation. Our data support a one-step model in which knowledge about the context and the world, concomitant information from other modalities, and the speaker are brought to bear immediately, by the same fast-acting brain system that combines the meanings of individual words into a message-level representation. Underlying the one-step model is the immediacy assumption, according to which all available information will immediately be used to co-determine the interpretation of the speaker's message. Functional magnetic resonance imaging data that we collected indicate that Broca's area plays an important role in semantic unification. Language comprehension involves the rapid incorporation of information in a 'single unification space', coming from a broader range of cognitive domains than presupposed in the standard two-step model of interpretation. 相似文献

The scientific attainments of medical science have advanced greatly in this generation. The art of the practice of medicine has not kept pace. The kindly spirit, unselfish service, and spiritual uplift which were characteristic of most physicians in the "horse-and-buggy days" are needed more today than they were a generation ago. A combination of medical science and spiritual counseling will do much to relieve the sufferings of mind and body. The personal physician-patient relationship and the building up of the patient's confidence in his physician are a most important aspect of the physician's duty. A belief in God and a knowledge of the availability of help from above is of great benefit to both physician and patient. 相似文献
