In the Moment

Many individuals, including some dance scholars, think that traditional dance genres are reified choreographic forms that are like physical objects, handed down unchanged and unchanging through time like heirlooms. Traditional dance genres do change through their history. In fact, many traditional genres contain a great deal of improvisation, which promotes change within the genre. Some dance genres, such as tango and Iranian solo urban dance, consist almost entirely of improvised movement. This essay describes and analyzes several dance genres and the ways in which improvisation informs them. The essay also details the characteristics of improvisation in general, and then use several genres of dance as examples of how dancers improvise within them.

It is easy to ignore small, concrete, and idiosyncratic details as unimportant in our inquiries into management processes. Indeed, at the moment, we feel that if we are to improve them and to avoid mistakes, then we must still seek a better understanding of them in the same way that we seek a better understanding of all else in the world around us in the proposing of theories of the supposed ‘hidden’ causes responsible for the outcomes of the management process, and in seeking and discussing evidence in favor of (and against) such explanatory theories. In other words, we adopt the same mode of inquiry toward other people (and other living things) as toward inert, physical objects. Wittgenstein’s philosophy, however, is oriented toward showing us that if we fail to distinguish between the relations we can have with living beings as compared to those with dead things, then we can mislead ourselves in ways that can have disastrous consequences for us. With respect to the process of managing, instead of achieving an easy familiarity with it, our current methods of inquiry can lead us to achieve only the power of manipulation and control. Rather than our understanding regularities and repetitions, Wittgenstein’s methods can help us understand how we can arrive at unique understandings of unique persons and events - the kind of understandings that enable us to ‘go on’ in a practical situation.

The high resolution STEM is now a fact of life. I think that we have, in the last few years, demonstrated that this instrument is capable of the same resolving power as a CEM but is sufficiently different in its imaging characteristics to offer some real advantages.It seems possible to prove in a quite general way that only a field emission source can give adequate intensity for the highest resolution^ and at the moment this means operating at ultra high vacuum levels. Our experience, however, is that neither the source nor the vacuum are difficult to manage and indeed are simpler than many other systems and substantially trouble-free.

Sectioned tissue rarely indicates evidence of what is probably a highly dynamic state of activity in mitochondria which have been reported to undergo a variety of movements such as streaming, divisions and coalescence. Recently, mitochondria from the rat anterior pituitary have been fixed in a variety of configurations which suggest that conformational changes were occurring at the moment of fixation. Pinocytotic-like vacuoles which may be taking in or expelling materials from the surrounding cell medium, appear to be forming in some of the mitochondria. In some cases, pores extend into the matrix of the mitochondria. In other forms, the remains of what seems to be pinched off vacuoles are evident in the mitochondrial interior. Dense materials, resembling secretory droplets, appear at the junction of the pores and the cytoplasm. The droplets are similar to the secretory materials commonly identified in electron micrographs of the anterior pituitary.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Traumatic brain injury (TBI) is a serious epidemic in the United States. It affects patients of all ages, race, and socioeconomic status (SES). The current care of these patients typically manifests after sequelae have been identified after discharge from the hospital, long after the inciting event. The purpose of this article is to introduce the concept of identification and management of the TBI patient from the moment of injury through long-term care as a multidisciplinary approach. By promoting an awareness of the issues that develop around the acutely injured brain and linking them to long-term outcomes, the trauma team can initiate care early to alter the effect on the patient, family, and community. Hopefully, by describing the care afforded at a trauma center and by a multidisciplinary team, we can bring a better understanding to the armamentarium of methods utilized to treat the difficult population of TBI patients.
