SPAN security policies and guidelines

A guide is provided to system security with emphasis on requirements and guidelines that are necessary to maintain an acceptable level of security on the network. To have security for the network, each node on the network must be secure. Therefore, each system manager, must strictly adhere to the requirements and must consider implementing the guidelines discussed. There are areas of vulnerability within the operating system that may not be addressed. However, when a requirement or guideline is discussed, implementation techniques are included. Information related to computer and data security is discussed to provide information on implementation options. The information is presented as it relates to a VAX computer environment

A molecular analysis of the tissue polarity gene prickle and associated transcripts in Drosophila melanogaster.

The distinct patterns of bristles and hairs on the surface of an adult Drosophila indicate a planar polarity and reflect the polarity of the underlying structures. Many of the planar polarity genes have been analysed molecularly and found to encode a diverse group of proteins. In this thesis, I describe the molecular characterisation of prickle. Three classes of mutation are found at the prickle locus; prickle (pkpk), spiny- legs (pksple) and prickle-spiny-legs (pkpk-sple). Three transcripts were identified and sequenced. The 4.2 kb pk transcript has seven exons that span 70 kb. The other two transcripts, sple and pkM, share six exons with pk and have alternatively spliced 5' ends. The GAL4-UAS system was used to demonstrate rescue of the prickle and spiny-legs phenotypes with the pk and sple transcripts, respectively. Overexpression of the UAS[pk+] construct also resulted in a phenotype resembling loss-of-function pksple and vice versa. The transcripts encode novel proteins with three LIM or UM-like motifs in the shared exons. LIM domains are cysteine rich sequences known to be involved in protein- protein interactions. A novel domain, named the PET domain, was also identified in these proteins just upstream of the LLM motifs. Database searches found the PET domain conserved in a small group of proteins. A Drosophila homologue, espinas (esn), was also identified and sequenced. A cluster of transcripts was found in the region of the 5' exon of the pk transcript. These were sequenced and shown to have homology to serine proteinase inhibitors or serpins. The most distal of the three was shown to rescue the necrotic phenotype. The possible roles of prickle in planar polarity signalling are discussed and it is suggested that the prickle proteins may be involved in the formation of multiprotein complexes

Disadvantaged gifted and talented students who make it to college and those who don\u27t: Implications for school leaders

Gifted and talented education students demonstrate outstanding ability in the areas of general intelligence, creative thinking, productive thinking, leadership, the visual arts, the performing arts, or an academic aptitude in a specified area. This study is a comparative, qualitative analysis of two groups of disadvantaged students who were categorized as gifted and talented in elementary school, and their postsecondary goals. Twelve students of cross-cultural backgrounds are included in the study. The academic journey of the students from elementary through secondary school, and the factors that determined whether they made it to college or not are the focus of the study. The researcher draws comparisons between the students\u27 personal experiences including community and institutional influences. A goal of the research was to gain insight regarding disadvantaged, gifted students. The results are intended to assist educators with ideas for pro-active planning in meeting the needs of disadvantaged, gifted students, relative to college aspirations

Self-Regulation Training for Control of Hypertension

Over the past 10 years controlled clinical studies have demonstrated that antihypertensive medication can prevent deaths from stroke, congestive heart failure, peripheral vascular disease, and kidney disease, even in patients with borderline (140/90-160/95) hypertension. Today, a new treatment method of psychophysiologic self-regulation developed over a 5-year period suggests that many patients are able gradually to eliminate these medications while restoring or maintaining normotensive blood pressure levels. Follow-up indicates that a healthier homeostatic balance is achieved and stress management maintained without need for continued daily practice of self-regulation. Subsequent to the writing of this report, an additional 50 patients have been treated with this method, both individually and in groups, with equally good results. Results indicate that 75-80 per cent of patients will find it possible to comply with the training regimen, as taught at The Menninger Foundation, and will become normotensive without drugs. This is one of a series of articles that appeared in the proceedings of the Second National Conference on Emotional Stress and Heart Disease, published in the Journal of the South Carolina Medical Association, November, 1979
