The Ideal

Environmental idealism is rooted in our Western religious traditions, according to which the quality of our surroundings has fallen, because of our sins, from some Garden of Eden ideal to its present deplorable state. Through our faith and work it is eventually to be redeemed to new glory (formerly only in Paradise, now thought to be awaited in this world).By contrast, measurements on the environment, based on scientific realism, approach the ideal by stages, the simplest being the notion of death as exemplified in the pioneer "limiting factors" approach of A. G. Huntsman. Today's examples include, among other things, the monitoring of air and water as pollutants.Experiments by F. E. J. Fry led him to replace the negative idea of lethal factors with the positive concept of "scope for activity." Extension of the latter idea, when applied to the human environment, brings in consideration of the "quality of life," which is associated, on this continent, with the name of Ian L. McHarg. It has brought with it, multidisciplinary measurements that lead to the planned division of a large area, say a river valley, into zones for optimal distribution of man's activities.Thus a beginning is made of reconciliation between the humanistic vision and the age of realism. The possibilities of developing a unified system are discussed.

The Ideal

Clinical supervision is fundamental to the training and development of professional psychologists; however, no clear supervision methods have been developed, and the ideal competencies for psychologists and supervisors are yet to be defined. This lack of consensus is aggravated in the field of clinical neuropsychology supervision due to the dearth of literature available, which has an impact not only in the supervisory activities and the training of new professionals, but also ultimately in the quality of service provided to people that in many cases could be considered to be a vulnerable population. The theoretical background provided in this review covers conceptual developments and debates in relation to clinical supervision. Specifically, it reflects on the definition of supervision in the context of neuropsychology, as well as competencies and practices required in order to render supervision. A brief review of supervision in the field of clinical neuropsychology is included. Additionally, some insights are offered into the dearth of research and theoretical developments in this area. Finally, some comments are included in relation to the professional progress of clinical neuropsychology in developing countries, with particular reference to South Africa.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Microscopic Investigations

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

Comprehensive Study

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

Definition Of

The definition of the multimorbidity concept reveals insufficient specificity of the comorbidity and multimorbidity definitions and, as a result, confusion in the use of these terms. Most authors are unanimous that the “core” of multimorbidity is presence of more than one disease in a patient. These coexisting diseases can be pathogenetically interconnected and non-interconnected. Regardless, the degree of multimorbidity always affects prognosis and quality of life.

The first flush phenomenon of urban wet weather discharges is presently a controversial subject. Scientists do not agree with its reality, nor with its influences on the size of treatment works. Those disagreements mainly result from the unclear definition of the phenomenon. The objective of this article is first to provide a simple and clear definition of the first flush and then to apply it to real data and to obtain results about its appearance frequency. The data originate from the French database based on the quality of urban wet weather discharges. We use 80 events from 7 separately sewered basins, and 117 events from 7 combined sewered basins. The main result is that the first flush phenomenon is very scarce, anyway too scarce to be used to elaborate a treatment strategy against pollution generated by urban wet weather discharges.

This chapter engages humanism and its fundamental assumptions by working through critical theory, black feminism, and black studies. It contends that there is a tension at the heart of humanism—while the ideal human appears to be the most widespread and available category, it has been constructed over and against certain qualities, beings, and threats. To elaborate on this tension, this chapter revisits the work of authors like Karl Marx and Michel Foucault. Marx acknowledges that the human is a site of conflict and antagonism even as his thought betrays a lingering commitment to progress and humanism. Foucault goes further than Marx by underscoring the fabricated quality of man and the ways in which racism functions to draw lines between those who must live and those who must die. In response to Marx and Foucault’s tendency to privilege Europe, this chapter engages black feminism and Afro-pessimism—Sylvia Wynter, Hortense Spillers, and Frank Wilderson—who show how the figure of the human within humanism is defined in opposition to blackness.
