AbstractThe rationale behind any construction project varies; it might be to achieve value, time, quality, cost or just satisfaction for the client. Irrespective of any or all of these reasons, the team members involved in conception, inception, construction and delivery of a project are aware that a good teamwork is of essence. This is in the context of growing needs of client and the ever-growing improvement in methods of project delivery as influenced by technology. This article looks into the team type in the Nigerian construction industry from the angle of a virtual team (VT) using the mixed-method research design. VT is simply a type of team wherein the members operate from different geographical regions and function majorly with the aid of information and communications technology media. Data for the study were collected from relevant literature, interviews were conducted with 20 selected professionals in the construction industry and, thereafter, a questionnaire was drafted from the results of the interviews and administered to selected relevant professionals. The study revealed that communication among team members, flexibility of operation and decision making are usually the most influencing strengths of the VT, while some of its weaknesses are a need for special training, conflict among team members and client’s acceptance of team type. Reduction in time-to-market, collaboration ability of team members and delivery time of project were seen as opportunities, while recognized threats were members’ performance level and complexity of technical application. The study concludes that the success of the VT depends highly on exploiting the opportunities opened to it.

The performance of the South Sumatra Provincial Government is reflected in the quality of innovation, program development, public services, and administrative processes related to the task and function of improving people's welfare. Performance productivity is measured by reducing poverty, increasing economic growth, and increasing local income. One of the improvements in performance is the work of middle level management in addition to the work of other levels of top management and low management. This study will answer the question of what factors can significantly to improve the performance of the government of South Sumatra Province. This paper will examine the factors of self-efficacy and affective commitment which are seen as determinants of improving the performance of the government of South Sumatra province, because it is one of the advantages of human resources and is a productive added value. However, previous studies on self-efficacy and affective commitment provide evidence that these two factors produce inconsistent research findings or gaps. Therefore empirically recommends that the effect of self-efficacy and affective commitment to improve performance requires further research to be justified. To resolve the gap of self-efficacy and affective commitment to the performance of the government of South Sumatra province, researchers adopted the theory of goal setting with the concept of competitive leadership with good organizational indicators, applying technology, sustainable work programs, and developing wider networks as a result of efficacy self and affective commitment can henceforth be used to improve organizational performance. The sample was used 108 respondents who held administrative positions with SEM LISREL 9.30 data processing. This conceptual model is expected to prove thatcompetitive shared leadership that is influenced by self-affication and affective commitment significantly improves the performance of the government of South Sumatra province.

This chapter reviews current trends in the literature related to the influence of vertical and shared leadership styles in the context of virtual teams, unpacking the influence of team structure and task structure to better understand the mechanisms influencing team effectiveness. The authors start by reviewing key features of virtual teams and different aspects of leadership and its influence in the virtual team environment. They argue that both vertical and shared leadership have strengths and limitations, and both styles may complement one another. The authors discuss the influence of leadership on virtual team processes and outcomes and examine contingency factors related to team and task structure in order to identify the boundary conditions for the effectiveness of vertical and shared leadership. The chapter offers a conceptual framework to guide future research in this domain.

And Function

The present knowledge of the three-dimensional structure of ribosomes is far too limited to enable a complete understanding of the various roles which ribosomes play in protein biosynthesis. The spatial arrangement of proteins and ribonuclec acids in ribosomes can be analysed in many ways. Determination of binding sites for individual proteins on ribonuclec acid and locations of the mutual positions of proteins on the ribosome using labeling with fluorescent dyes, cross-linking reagents, neutron-diffraction or antibodies against ribosomal proteins seem to be most successful approaches. Structure and function of ribosomes can be correlated be depleting the complete ribosomes of some proteins to the functionally inactive core and by subsequent partial reconstitution in order to regain active ribosomal particles.

Introduction: Oxidized cholesterol derivatives have been demonstrated in various cell cultures to be very potent inhibitors of 3-hvdroxy-3- methylglutaryl Coenzyme A reductase which is a principle regulator of cholesterol biosynthesis in the cell. The cholesterol content in the cells exposed to oxidized cholesterol was found to be markedly decreased. In aortic smooth muscle cells, the potency of this effect was closely related to the cytotoxicity of each derivative. Furthermore, due to the similarity of their molecular structure to that of cholesterol, these oxidized cholesterol derivatives might insert themselves into the cell membrane, alter membrane structure and function and eventually cause cell death. Arterial injury has been shown to be the initial event of atherosclerosis.

Cat Superior Colliculus

The first visual cortical axons arrive in the cat superior colliculus by the time of birth. Adultlike receptive fields develop slowly over several weeks following birth. The developing cortical axons go through a sequence of changes before acquiring their adultlike morphology and function. To determine how these axons interact with neurons in the colliculus, cortico-collicular axons were labeled with biocytin (an anterograde neuronal tracer) and studied with electron microscopy.Deeply anesthetized animals received 200-500 nl injections of biocytin (Sigma; 5% in phosphate buffer) in the lateral suprasylvian visual cortical area. After a 24 hr survival time, the animals were deeply anesthetized and perfused with 0.9% phosphate buffered saline followed by fixation with a solution of 1.25% glutaraldehyde and 1.0% paraformaldehyde in 0.1M phosphate buffer. The brain was sectioned transversely on a vibratome at 50 μm. The tissue was processed immediately to visualize the biocytin.

Structure and function of intercellular junctions were studied under the electronmicroscope using conventional thin sectioning and freeze-etch replicas. Alterations of tight and gap junctions were analyzed 1. of exocrine pancreatic cells under cell isolation conditions and pancreatic duct ligation and 2. of hepatocytes during extrahepatic cholestasis.During the different steps of cell isolation of exocrine pancreatic cells, gradual changes of tight and gap junctions were observed. Tight junctions, which formed belt-like structures around the apex of control acinar cells in situ, subsequently diminished, became interrupted and were concentrated into macular areas (Fig. 1). Aggregations of membrane associated particles, which looked similar to gap junctions, were intermixed within tight junctional areas (Fig. 1). These structures continously disappeared in the last stages of the isolation procedure. The intercellular junctions were finally separated without destroying the integrity of the cell membrane, which was confirmed with porcion yellow, lanthanum chloride and horse radish peroxidase.

Ribosomes are ribonucleoprotein particles necessary for processing the genetic information of mRNA into proteins. Analogy in composition and function of ribosomes from diverse species, established by biochemical and biological assays, implies their structural similarity. Direct evidence obtained by electron microscopy seems to be of increasing relevance in understanding the structure of ribosomes and the mechanism of their role in protein synthesis.The extent of the structural homology between prokaryotic and eukaryotic ribosomes has been studied on ribosomes of Escherichia coli (E.c.) and Artemia salina (A.s.). Despite the established differences in size and in the amount and proportion of ribosomal proteins and RNAs both types of ribosomes show an overall similarity. The monosomes (stained with 0.5% aqueous uranyl acetate and deposited on a fine carbon support) appear in the electron micrographs as round particles with a diameter of approximately 225Å for the 70S E.c. (Fig. 1) and 260Å for the 80S A.s. monosome (Fig. 2).

Active Investigation

The morphology and function of the vestibular sensory organs has been extensively studied during the last decade with the advent of electron microscopy and electrophysiology. The opening of the space age also accelerated active investigation in this area, since this organ is responsible for the sensation of balance and of linear, angular and gravitational acceleration.The vestibular sense organs are formed by the saccule, utricle and three ampullae of the semicircular canals. The maculae (sacculi and utriculi) have otolithic membranes on the top of the sensory epithelia. The otolithic membrane is formed by a layer of thick gelatin and sand-piles of calcium carbonate crystals (Fig.l).
