Findings from non-participant observational data concerning health promoting nursing practice in the acute hospital setting focusing on generalist nurses.

AIM This paper reports on the non-participant observational findings from a study, which examined hospital-based nurses' health promoting nursing practice in an acute setting. BACKGROUND Nurses are considered to have a key role in health promotion. However, the development of the role of the generalist hospital-based nurse in health promotion has been slow and is not well-understood. METHOD The conceptual framework used was based on the Ottawa Charter (WHO 1986). A single qualitative embedded case study, employing data source and methodological triangulation was used. A framework for identifying nurse's use of health promotion methods was developed and used to collect non-participant observations on a purposive sample of eight nurses working on an acute hospital ward. Following the observations a semi structured one-to-one interview was conducted with each observed nurse. One randomly selected patient that the observed nurse had cared for during the observations was also interviewed. Qualitative data analysis based on the work of Miles and Huberman was employed. RESULTS Two categories were identified 'health promotion strategies and content' and 'patient participation'. The findings indicated that, overall, the strategies used by nurses to promote health were prescriptive and individualistic. The main strategy observed was information giving and the content was 'preparatory information'. Predominantly, nurses practised traditional health education. Overall, patient participation was limited to minor personal aspects of care as nurses focused on the routine and getting the tasks completed. There was no evidence of a ward culture which valued health promotion. CONCLUSIONS Ward managers are key in creating a culture for health promotion. A review of the methods of organizing nursing care is warranted. RELEVANCE TO CLINICAL PRACTICE Nursing programmes must highlight health promotion as integral to practice and emphasis the socio-political dimensions of health promotion.
Transverse Skin Crease versus Vertical Midline Incision versus Laparoscopy for Right Hemicolectomy: A Systematic Review—Current Status of Right Hemicolectomy

Purpose. The right hemicolectomy may be conducted through laparoscopic or laparotomic surgery, transverse or midline incisions. The transverse laparotomy offers some advantages compared to the midline laparotomy and laparoscopy. A literature review was performed to evaluate the possible advantages of the transverse incision versus midline incision or laparoscopic right hemicolectomy. Methods. A systematic research was performed in Medline, Embase, Cochrane Central Register of Controlled Trials, CINAHL, BioMed Central, and the Science Citation Index. Results. Laparotomic right hemicolectomy with transverse incision is preferable to laparotomic hemicolectomy with midline incision. A transverse incision offers a lessened postoperative pain following physical activity, a lessened need to administer analgesic therapy during the post-operative time, better aesthetic results, and a better post-operative pulmonary function. Open surgery with transverse or midline incision ensured a shorter operative time, lower costs and a greater length of the incision compared to the laparoscopic. However, there are no differences in the oncological outcomes. Conclusions. It was not possible to identify significant differences between the open right hemicolectomy with transverse incision versus the open right hemicolectomy with midline incision or laparoscopic hemicolectomy.
PRIVACY-PRESERVING AUTHENTICATION USING FINGERPRINT

Biometrics provides us with an effective tool for authentication and is becoming a strong competitor in current authentication mechanisms. However, the concerns about biometrics regarding template security, privacy and revocability impede its further application to network-based scenarios. We propose a novel fingerprint minutiae-based scheme to achieve reliable mutual authentication over insecure channels. In the proposed scheme, a private template is generated which is completely random and independent of the minutiae, thus providing template protection, privacy preservation and revocability. A private matching scheme is embedded in an authentication protocol to ensure that both a server and a user can verify each other by matching the template against the query minutiae without revealing their respective inputs. We analyze the security of the proposed scheme under various attack scenarios. The experimental results on FVC2002-DB2 show that the scheme’s verification accuracy is acceptable.
Functional adult literacy and empowerment of women: Impact of a functional literacy program In Turkey

The study we discuss here addresses the impact of functional adult literacy on the empowerment of women in the absence of formal schooling. Our over-all goal was to examine whether the effects of functional literacy are exclusively content-specific or whether there are gains going beyond the obvious benefits extending to other spheres of everyday functioning including cognitive personal and interpersonal. We studied a development intervention program implemented in Turkey the Functional Adult Literacy Program (FALP) for its impact beyond specific gains in literacy. The purpose of the study was to observe the influence of the literacy program on the cognitive personal familial and social spheres of participants lives. Our focus is on these issues rather than the impact of the program on becoming more literate. The research comprised two studies. The first study looked at the transfer to daily life of skills gained during FALP. The second study was a follow-up that examined the specific manifestations of such transformational changes and institutionalization of these transformations a year later in the lives of the participants. The theoretical framework of this article is based on the converging point of two separate lines of thought: [(1)] the arguments of functional adult literacy as am empowering process and [(2)] the "capabilities" approaches of Sen (1985) and Nussbaum (2000) stemming from the critiques of social justice theories.

State Space-Vector Model of Linear Induction Motors

This paper presents the state space-vector dynamic model of the linear induction motor (LIM) taking into consideration the dynamic end effects. Starting from the space-vector equivalent circuit of the LIM, the complete set of space-vector equations has been deduced. Afterward, first the so-called voltage and current flux models have been written, from which the complete state space-vector representation has been given. The complete thrust expression including the end-effect braking force has also been introduced in the model. The complete state space-vector model, electromagnetic and mechanical part, has been implemented in numerical simulation and has been validated by comparing the results with those obtainable with a finite-element analysis and experiments. Results show that, even with a machine with a limited presence of the dynamic end effects, the adoption of a this model permits a better estimation of both the electric quantities, e.g., inductor current, and the mechanical quantities, e.g., linear speed, with respect to the classic rotating induction motor model.
Germ line stem cell differentiation in Drosophila requires gap junctions and proceeds via an intermediate state

Gap junctions coordinate processes ranging from muscle contraction to ovarian follicle development. Here we show that the gap junction protein Zero population growth (Zpg) is required for germ cell differentiation in the Drosophila ovary. In the absence of Zpg the stem cell daughter destined to differentiate dies. The zpg phenotype is novel, and we used this phenotype to genetically dissect the process of stem cell maintenance and differentiation. Our findings suggest that germ line stem cells differentiate upon losing contact with their niche, that gap junction mediated cell-cell interactions are required for germ cell differentiation, and that in Drosophila germ line stem cell differentiation to a cystoblast is gradual.
The Impact of the Human DNA Topoisomerase II C-Terminal Domain on Activity

Background Type II DNA topoisomerases (topos) are essential enzymes needed for the resolution of topological problems that occur during DNA metabolic processes. Topos carry out an ATP-dependent strand passage reaction whereby one double helix is passed through a transient break in another. Humans have two topoII isoforms, α and β, which while enzymatically similar are differentially expressed and regulated, and are thought to have different cellular roles. The C-terminal domain (CTD) of the enzyme has the most diversity, and has been implicated in regulation. We sought to investigate the impact of the CTD domain on activity. Methodology/Principle Findings We have investigated the role of the human topoII C-terminal domain by creating constructs encoding C-terminally truncated recombinant topoIIα and β and topoIIα+β-tail and topoIIβ+α-tail chimeric proteins. We then investigated function in vivo in a yeast system, and in vitro in activity assays. We find that the C-terminal domain of human topoII isoforms is needed for in vivo function of the enzyme, but not needed for cleavage activity. C-terminally truncated enzymes had similar strand passage activity to full length enzymes, but the presence of the opposite C-terminal domain had a large effect, with the topoIIα-CTD increasing activity, and the topoIIβ-CTD decreasing activity. Conclusions/Significance In vivo complementation data show that the topoIIα C-terminal domain is needed for growth, but the topoIIβ isoform is able to support low levels of growth without a C-terminal domain. This may indicate that topoIIβ has an additional localisation signal. In vitro data suggest that, while the lack of any C-terminal domain has little effect on activity, the presence of either the topoIIα or β C-terminal domain can affect strand passage activity. Data indicates that the topoIIβ-CTD may be a negative regulator. This is the first report of in vitro data with chimeric human topoIIs.
Traffic studies for DSA policies in a simple cellular context with packet services

DSA (Dynamic Spectrum Allocation) techniques are very challenging when the quality of service has to be guaranteed in a flexible spectrum situation. In this paper, we present and analyze DSA policies for packet services in cellular context. A centralized model, where a meta-operator shares a common spectrum among different operators, is considered. We focus on two criteria for the policies design: the total welfare (sum of operators' rewards), and the blocking probability. We go through two steps to pass from the actual FSA (Fixed Spectrum Allocation) situation into DSA. First, DSA algorithms depend on the arrival rates. Second, DSA algorithms depend on both the arrival rates as well as the number of active users. Targeting the reward maximization shows to be inefficient when the blocking probability has to be guaranteed. However policies targeting a blocking probability threshold, achieve greater rewards then FSA rewards. We also present a heuristic DSA algorithm that takes into consideration: the arrival rates, the number of active users and the blocking probability. The algorithm gives a very close blocking probability to the one achieved using FSA, while the obtained reward significantly exceeds the FSA reward.
Convergence of a hybrid scheme for the elliptic Monge-Ampere equation

We prove the convergence of a hybrid discretization to the viscosity solution of the elliptic Monge-Ampere equation. The hybrid discretization uses a standard finite difference discretization in parts of the computational domain where the solution is expected to be smooth and a monotone scheme elsewhere. A motivation for the hybrid discretization is the lack of an appropriate Newton solver for the standard finite difference discretization on the whole domain.
Biocomputing: numerical simulation of glioblastoma growth using diffusion tensor imaging

Glioblastoma multiforma (GBM) is one of the most aggressive tumors of the central nervous system. It can be represented by two components: a proliferative component with a mass effect on brain structures and an invasive component. GBM has a distinct pattern of spread showing a preferential growth in the white fiber direction for the invasive component. By using the architecture of white matter fibers, we propose a new model to simulate the growth of GBM. This architecture is estimated by diffusion tensor imaging in order to determine the preferred direction for the diffusion component. It is then coupled with a mechanical component. To set up our growth model, we make a brain atlas including brain structures with a distinct response to tumor aggressiveness, white fiber diffusion tensor information and elasticity. In this atlas, we introduce a virtual GBM with a mechanical component coupled with a diffusion component. These two components are complementary, and can be tuned independently. Then, we tune the parameter set of our model with an MRI patient. We have compared simulated growth (initialized with the MRI patient) with observed growth six months later. The average and the odd ratio of image difference between observed and simulated images are computed. Displacements of reference points are compared to those simulated by the model. The results of our simulation have shown a good correlation with tumor growth, as observed on an MRI patient. Different tumor aggressiveness can also be simulated by tuning additional parameters. This work has demonstrated that modeling the complex behavior of brain tumors is feasible and will account for further validation of this new conceptual approach.
Growth, Income Inequality, and Fiscal Policy: What Are the Relevant Trade-offs?

We develop an endogenous growth model with elastic labor supply, in which agents differ in their initial endowments of physical capital. In this context, the growth rate and the distribution of income are jointly determined. We then examine the distributional impact of different ways of financing an investment subsidy. Policies aimed at increasing the growth rate result in a more unequal distribution of pre-tax income, consistent with the positive correlation between income inequality and growth observed in the recent empirical literature. However, there is no conflict between efficiency and equity if inequality is measured in terms of the distribution of welfare. Copyright 2007 The Ohio State University.
Data Conversion Method between a Natural Number and a Binary Tree for an Inductive Proof and Its Application

This paper presents modeling of a binary tree that represents a natural number and gives an inductive proof for its properties using theorem provers. We dene a function for converting data from a natural number into a binary tree and give an inductive proof for its well-denedness. We formalize this method, develop a computational model based on it, and apply it to an electronic cash protocol. We also dene the payment function on the binary tree and go on to prove the divisibility of electronic cash using the theorem provers Isabelle/HOL and Coq, respectively. Furthermore, we discuss the eectiveness of
Long-chain n-3 DHA reduces the extent of skeletal muscle fatigue in the rat in vivo hindlimb model

Dietary fish oil modifies skeletal muscle membrane fatty acid composition and oxygen efficiency similar to changes in the myocardium. Oxygen efficiency is a key determinant of sustained force in mammalian skeletal muscle. Therefore, in the present study, we tested the effects of a fish-oil diet on skeletal muscle fatigue under the stress of contraction using the rat in vivo autologous perfused hindlimb model. For 8 weeks, male Wistar rats were fed a diet rich in saturated fat (SF), a diet rich in n-6 PUFA or a diet rich in long-chain (LC) n-3 PUFA DHA derived from fish oil. In anaesthetised, mechanically ventilated rats, with their hindlimbs perfused with arterial blood at a constant flow, the gastrocnemius–plantaris–soleus muscle bundle was stimulated via sciatic nerve (2 Hz, 6–12 V, 0·05 ms) to contract repetitively for 30 min. Rats fed the n-3 PUFA diet developed higher maximum twitch tension than those fed the SF and n-6 PUFA diets (P< 0·05) and sustained twitch tension through more repetitions before the tension declined to 50 % of the maximum twitch tension (P< 0·05). The n-3 PUFA group used less oxygen for tension developed and produced higher venous lactate concentrations with no difference in glycogen utilisation compared with the SF and n-6 PUFA groups. These results further support that incorporation of DHA into skeletal muscle membranes increases the efficiency of oxygen use over a range of contractile force and this is expressed as a higher sustained force and prolonged time to fatigue.
Finite-size-scaling analysis of domain growth in the kinetic Ising model with conserved and nonconserved order parameters.

Standard finite-size-scaling techniques are introduced to obtain domain growth exponents during a first-order phase transition. A scaling ansatz for the nonequilibrium structure factor in a finite lattice is presented. It explicitly includes a time rescaling exponent x, related to the domain growth exponent n (n=1/x). We first analyze domain growth in the kinetic Ising model with a nonconserved order parameter. The method correctly gives the expected exponent n=1/2. We have also studied the kinetic Ising model with a conserved order parameter at a critical value of the order parameter. The scaling behavior of the peak of the structure factor is consistent with n\ensuremath{\approxeq}0.27. The analysis of higher wave numbers is more consistent, however, with n\ensuremath{\approxeq}0.33.
ADRC controller used in dynamic positioning system of a rescue ship

Dynamic positioning system of marine vehicles has been undergoing a rapid development and application. In this paper a maneuvering mathematical model and a pure sway motion model with three degrees of freedom are established, an ADRC controller for the dynamic positioning system of a rescue ship is designed. The results of simulation indicate that the control performance and robustness of ADRC is significantly better than conventional PID controller, the outputs of rudder angle and pitch of CPP are smoother and gentler improved, the steady state accuracy of control output is better, the adaptability of parameters is extensive. Taking pure sway motion of the rescue ship for example, rapidity and effectiveness of a proposed multi-mode controller are verified.
Minimising risks in IT outsourcing: Choosing target services

This paper provides a risk-based framework for deciding on which IT services to outsource and which to keep in-house. This framework considers the probabilities both of negative outcomes, and of failing to achieve positive outcomes. The authors examine the major components of outsourcing risk and their drivers, and from this derive a series of questions decision-makers can ask when deciding what sourcing options to adopt for different services. The framework was developed on the basis of five years of qualitative and quantitative research into the experiences of organizations involved in outsourcing IT.
Placental-Specific sFLT-1 e15a Protein Is Increased in Preeclampsia, Antagonizes Vascular Endothelial Growth Factor Signaling, and Has Antiangiogenic Activity

In preeclampsia, the antiangiogenic factor soluble fms-like tyrosine kinase-1 (sFLT-1) is released from placenta into the maternal circulation, causing endothelial dysfunction and organ injury. A recently described splice variant, sFLT-1 e15a, is primate specific and the most abundant placentally derived sFLT-1. Therefore, it may be the major sFLT-1 isoform contributing to the pathophysiology of preeclampsia. sFLT-1 e15a protein remains poorly characterized: its bioactivity has not been comprehensively examined, and serum levels in normal and preeclamptic pregnancy have not been reported. We generated and validated an sFLT-1 e15a–specific ELISA to further characterize serum levels during pregnancy, and in the presence of preeclampsia. Furthermore, we performed assays to examine the bioactivity and antiangiogenic properties of sFLT-1 e15a protein. sFLT-1 e15a was expressed in the syncytiotrophoblast, and serum levels rose across pregnancy. Strikingly, serum levels were increased 10-fold in preterm preeclampsia compared with normotensive controls. We confirmed sFLT-1 e15a is bioactive and is able to inhibit vascular endothelial growth factor signaling of vascular endothelial growth factor receptor 2 and block downstream Akt phosphorylation. Furthermore, sFLT-1 e15a has antiangiogenic properties. sFLT-1 e15a decreased endothelial cell migration, invasion, and inhibited endothelial cell tube formation. Administering sFLT-1 e15a blocked vascular endothelial growth factor induced sprouts from mouse aortic rings ex vivo. We have demonstrated that sFLT-1 e15a is increased in preeclampsia, antagonizes vascular endothelial growth factor signaling, and has antiangiogenic activity. Future development of diagnostics and therapeutics for preeclampsia should consider targeting placentally derived sFLT-1 e15a.
Extended transfer bound error analysis in the presence of channel random nuisance parameter

In this paper, we present the extended transfer bound analysis for the error performance of a general trellis code in the channel with the overall correlated continuous valued nuisance parameters. We introduce proper parameter model and include it into a new extended form of the transfer function. In this way, both, the new additional parameter space and the original error space are incorporated into system error analysis. An example application with simple trellis code and Rayleigh fading channel is investigated in order to demonstrate the functionality of the principle. Computer simulation results are presented for two different codes and various fading scenarios, and comparisons are made among analytical and measured system error performances. It was shown that for fading amplitude our approach was able to predict correct error asymptotes
Responses of angiographically normal human coronary arteries to intracoronary injection of acetylcholine by age and segment. Possible role of early coronary atherosclerosis.

We examined the response of left coronary arteries to intracoronary injection of acetylcholine (ACh) 50 micrograms in 74 patients by measuring the diameter changes with a videodensitometric analysis system. Patients with angiographically normal coronary arteries were subdivided into a younger group of 26 patients (age, 9-29 years) and an older group of 23 patients (age, 31-68 years). In the younger group, the diameter at the distal segment of the left anterior descending artery (LAD) and at the proximal, middle, and distal segments of the left circumflex artery (LCx) increased significantly (16.7 +/- 19.3%, p less than 0.01, for LAD and 8.0 +/- 18.8%, p less than 0.05; 11.0 +/- 16.1%, p less than 0.01; and 19.8 +/- 17.5%, p less than 0.01, for LCx segments, respectively) in response to ACh. In the older group, on the other hand, the diameter at the proximal and middle segments of LAD and LCx decreased significantly (-20.8 +/- 16.9%, p less than 0.01; and -17.9 +/- 28.4%, p less than 0.01, for LAD segments and -14.6 +/- 17.4%, p less than 0.01; and -11.3 +/- 21.4%, p less than 0.05, for LCx segments, respectively). The dilator response to ACh in the younger group was significantly greater in the distal segment than in the proximal segment in both LAD and LCx (p less than 0.01 for LAD and p less than 0.05 for LCx). The constrictor response to ACh in the older group was significantly greater in the proximal than the distal segment in both LAD and LCx (p less than 0.05 for LAD and LCx, respectively).
