The method of quantitative burn-wound biopsy cultures and its routine use in the care of the burned patient.

A method for quantitative biopsy cultures of burn wounds has been developed and evaluated. Specimens are obtained by full-thickness biopsy of the burn wound using a scalpel. Specimens are processed by maceration, suspension in physiologic saline solution, and plating of serial dilutions of the suspension on appropriate media. Quantitative counts are performed and expressed as the number of bacteria per Gm. of burn-wound tissue. Experience with this technic in the care of 210 consecutive patients with burns of more than 20% total body surface area has shown it to be more reliable than surface-culture technics. Patients were considered to have wound colonization when 104 or more organisms per Gm. of burned tissue were recovered from different areas of the body. Appropriate antibiotic therapy was instituted on the basis of these results. Routine use of this method was found to be effective, simple, and practical as an aid in the early diagnosis of sepsis in the burned patient.
Predictability of stock returns: is it rational?

This study identifies three anomalies in the British capital markets. It is statistically proven that the logs of six stock prices, in the British stock market, are cointegrated with the logs of a market index, a bond price, and an exchange rate. This means that the lagged residual of each cointegration regression appears in the regression of the first-differences of the above variables in what has been called the error-correction regression. This anomaly means that past information is helpful in predicting current stock returns and this may be due either to the presence of a fad, or to forward-looking rationality. Two other anomalies are 1) the correlation of cointegration residuals across stocks, which may be explained by a common factor absent from the regressions and 2) the fact that it is the first-difference of the interest rate, instead of the level, that explains stock returns, which is consistent with the evidence that the level of the interest rate is non-stationary.
Computational hemodynamics of abdominal aortic aneurysms: Three-dimensional ultrasound versus computed tomography

The current criterion for surgical intervention in abdominal aortic aneurysms, based upon a maximal aortic diameter, is considered conservative due to the high mortality rate in case of rupture. The research community is actively investigating the use of computational mechanics tools combined with patient-specific imaging to help identify more accurate criteria. Widespread uptake of a successful metric will however be limited by the need for computed tomography, which is at present the primary image extraction method on account of the location and complex shape of the aneurysms. The use of three-dimensional ultrasound as the scanning method is more attractive on account of increased availability, reduced cost and reduced risk to patients. The suitability of three-dimensional ultrasound is assessed for this purpose in the present work; computational fluid dynamics simulations were performed on geometries obtained from the same patient using both ultrasound and computed tomography. The influence of different smoothing algorithms is investigated in the geometry preparation stage and Taubin’s low-pass filter was found to best preserve geometry features. Laminar, Newtonian, steady-state simulation analysis identified haemodynamic characteristics to be qualitatively similar in terms of wall shear stress, velocity and vorticity. The study demonstrates the potential for three-dimensional ultrasound to be integrated into a more accessible patient-specific modelling tool able to identify the need for surgical intervention of abdominal aortic aneurysms.

Projetos de TI: maturidade x desempenho

This article presents a survey done on 130 projects in the IT area that evaluated the relationship between the degree of maturity in project management of the performing organization and the project’s performance. The maturity was evaluated by the degree of formalization procedures of project management described in the PMBOK, and the performance of the projects was evaluated by Shenhar’s definition (2001). It was possible to verify that the processes of project management do not have the same relationship as to the performance project.
The Appeal to Values in the Management of International Non-Governmental Organisations: Linking Ethics and Practice

This article argues that there is a growing convergence between development INGOs and private sector organisations in the way that values are taken up as an instrument of management. Rather than promoting the exploration of difference, managers encourage employees to set aside their concerns and have faith in the organisational mission. In this way they exercise control without appearing to do so, and avoid dealing with the day to day difficulty of undertaking the work. Instead managers feel obliged to promise transformation, because of the increased marketisation and professionalisation of development. The article offers an alternative understanding of values as a profoundly social phenomenon requiring reflection and negotiation through and with others.
A TV Receiver Front-End With Linearized LNA and Current-Summing Harmonic Rejection Mixer

A low-noise and highly linear wideband receiver front-end composed of the linearized low noise amplifier and current-summing harmonic rejection mixer is implemented in a 0.18- <inline-formula> <tex-math notation="LaTeX">$\mu\text{m}$</tex-math></inline-formula> CMOS process for TV tuner applications. It shows a measured voltage gain <inline-formula> <tex-math notation="LaTeX">$(A_{v})$</tex-math></inline-formula> of more than 34.5 dB, a noise figure of less than 3.5 dB, and a third-order input-referred intercept point (IIP3) of more than −20 dBm in the frequency range from 44 to 880 MHz. The baseband coefficient scaling and summation based on the current mirror ensure a third- and fifth-harmonic rejection ratio of over 45 dBc in measurement with high linearity performance. The power consumption of the proposed TV receiver front-end is 16.2 mW at a 1.8-V supply voltage.
Can FTAA suspend the law of gravity and give the Americas higher growth and better income distributions ?

1. The export sector is the fundamental source of both wealth and inequality: You are what you export. Exporting manufactures has been essential for high incomes and low levels of inequality. Exporting crops and raw materials comes with low incomes and unequal income distributions. 2. The mix of exports is determined by three fundamentals: Resources, Remoteness, and Climate. Manufacturing likes cool climates, an educated workforce, and locations close to the high-wage marketplaces of Europe and North-America. 3. The volume of exports and the wealth formation that comes from the export sector can be impeded by inward looking, isolationist policies. Governments can affect the export mix only slightly and mostly through policies that alter the effects of the fundamental drivers, for example, by encouraging the formation of institutions that make a country effectively closer to global marketplaces.

The Self-Equalizing De Bruijn Sequence for 3D Profilometry

Using color in 3D proﬁlometry usually requires a tedious color calibration to mitigate the undesired effects of ambient lighting, object albedo, non-equal channel gains, and channel cross-talk. We propose a novel De Bruijn sequence for multi-channel structured light that removes the need for color calibration of a camera-projector pair. The proposed sequence has the following desirable properties: (1) it enables the extraction of ambient lighting, (2) it enables the cancellation of object albedo, and (3) it enables the equalization of channel gains.
Testing for subadditivity of vertically integrated electric utilities

The public policy debate over electric utility deregulation has a long history and generated a considerable amount of research. Much of this research focused on estimating the degree of scale economies in generation with little attention given to the effect vertical integration may have on cost structure. The vertical integration issue is important because most observers consider the transmission and distribution stages to be natural monopolies. According to Joskow and Schmalensee, economics of integration, if any, would link the production stages together, possibly extending natural monopoly conditions from transmission/distribution to generation even if the latter exhibited no economies of scale. 27 refs., 5 tabs.
Exploring the dynamic relationship between housing and retail property markets: an empirical study of Hong Kong

This paper investigates the dynamic conditional correlations (DCCs) between housing returns and retail property returns, and the existence of volatility spillover between the two property markets of Hong Kong. Two multivariate stochastic volatility models (MSV), namely Granger causality MSV and DCC-MSV model, are used to capture the time-varying correlations and the volatility spillover effect, respectively. The findings show that the correlations between housing returns and retail property returns follow a dynamic process, and such dynamic correlation could serve as a leading indicator for future property price movements. Besides, the findings also suggest that Hong Kong’s retail property market is generally more volatile than its residential market. Additionally, we find a unilateral volatility spillover from residential property to retail property in the Hong Kong market.
House Price Bubble Estimations in Australia’s Capital Cities with Market Fundamentals

Abstract This paper investigates the existence of house price bubbles in Australia’s eight capital cities in recent years by using quantitative analyses including Johansen cointegration test, Granger causality test, impulse response and Chow forecast test. While interactions between house prices and market fundamentals are discussed in long-run and causal estimations, shocks from the market fundamentals to house prices are investigated in generalized impulse response analyses. Findings from estimating house price bubbles for eight capital cities suggest that there was an obvious house price bubble in Perth, while a slight house price bubble occurred in Sydney. In contrast, house prices in Adelaide and Darwin can be explained very well by market fundamentals, while house prices in Melbourne, Brisbane, Hobart and Canberra were undervalued in the study period.
Modeling Page Views Across Multiple Websites with an Application to Internet Reach and Frequency Prediction

In this study, we develop a multivariate generalization of the negative binomial distribution NBD. This new model has potential application to situations where separate NBDs are correlated, such as for page views across multiple websites. In turn, our page view model is used to predict the audience for Internet advertising campaigns. For very large Internet advertising schedules, a simple approximation to the multivariate model is also derived. In a test of nearly 3,000 Internet advertising schedules, the two new models are compared with some proprietary and nonproprietary models previously used for Internet advertising and are shown to be significantly more accurate.
A New Perspective on Director Busyness

type="main" xml:lang="en"> We provide a new perspective to the multiple directorships literature, which focuses on outside directors. Inside directors, however, are important in both the boardroom and day-to-day operations of the firm. We find that any negative effect of director busyness is more pervasive for inside directors than for outside directors. Additional analysis reveals that bidding firms' acquisition announcement returns are decreasing in inside director board appointments, but there is no such effect for outside directors. These results highlight the importance of inside directors and demonstrate that firm performance can be compromised when they sit on multiple boards.

Salvaging The Ischaemic Penumbra: More Than Just Reperfusion?

1. The ischaemic penumbra is defined as a moderately hypoperfused region that retains structural integrity but has lost function. In animal models of ischaemic stroke, this region is prone to recurrent anoxic depolarization and will become infarcted if reperfusion does not occur. In the macaque model, an ischaemic penumbra has been identified for up to 3 h after ischaemic stroke onset, whereas in selected human patients it may exist for up to 48 h.
Managing employee performance in an emerging economy: perceptions of Vietnamese managers

This qualitative study explores employee performance management (PM) in Vietnam from the perspectives of Vietnamese managers in three case study organizations: a state-owned enterprise, a joint venture and a private Vietnamese company. Findings suggest that western PM practices and techniques are being utilized in all three organizations and that PM is seen as an essential and strategic component of human resource management policy. These findings suggest an increasing awareness of PM in Vietnamese enterprises and a desire to improve competitiveness by developing a highly skilled and high-performing workforce.
FDTD Simulation of Nonlinear Ultrasonic Pulse Propagation in ESWL

The extracorporeal shock wave lithotripsy (ESWL) has come into wide use due to its non-invasive advantage. However, as for the shock wave propagation in human body in relation to practical lithotripsy, there are a few studies on numerical simulation based on models conforming to practical situations. In this paper we report a numerical method of finite difference time domain (FDTD) for analyzing ultrasonic pulse nonlinear propagation in human body tissues and demonstrated it through an experiment of Reichenberger's ESWL in water
Productividad, acumulación y deseconomías públicas en el crecimiento económico colombiano

La tendencia del crecimiento economico colombiano paso de la aceleracion (anos 1930 a 1960) a la desaceleracion (anos 1970 a 1990). Esta reversion de la dinamica economica colombiana se relaciona con la disminucion tendencial de las ganancias en productividad. Para obtener este resultado se postula que el sector publico actua como un lastre del crecimiento economico (cuando debiera ser un motor). El impacto de las deseconomias publicas en la eﬁciencia de la acumulacion se analiza con el modelo de descomposicion del crecimiento de Hall (1988). La disminucion de la senda de crecimiento de la productividad es consecuencia del viraje del modelo de desarrollo industrialista hacia el aperturista.
A study protocol for a non-randomised comparison trial evaluating the feasibility and effectiveness of a mobile cognitive–behavioural programme with integrated coaching for anxious adults in primary care

Introduction Generalised anxiety disorder (GAD) and subclinical GAD are highly prevalent in primary care. Unmanaged anxiety worsens quality of life in patients seen in primary care practices and leads to increased medical utilisation and costs. Programmes that teach patients cognitive–behavioural therapy (CBT) techniques have been shown to improve anxiety and to prevent the evolution of anxiety symptoms to disorders, but access and engagement have hampered integration of CBT into medical settings. Methods and analysis This pragmatic study takes place in University of Pittsburgh Medical Center primary care practices to evaluate a coach-supported mobile cognitive– behavioural programme (Lantern) on anxiety symptoms and quality of life. Clinics were non-randomly assigned to either enhanced treatment as usual or Lantern. All clinics provide electronic screening for anxiety and, within clinics assigned to Lantern, patients meeting a threshold level of mild anxiety (ie, >5 on Generalised Anxiety Disorder 7-Item Questionnaire (GAD-7)) are referred to Lantern. The first study phase is aimed at establishing feasibility, acceptability and effectiveness. The second phase focuses on long-term impact on psychosocial outcomes, healthcare utilisation and clinic/provider adoption/sustainable implementation using a propensity score matched parallel group study design. Primary outcomes are changes in anxiety symptoms (GAD-7) and quality of life (Short-Form Health Survey) between baseline and 6-month follow-ups, comparing control and intervention. Secondary outcomes include provider and patient satisfaction, patient engagement, durability of changes in anxiety symptoms and quality of life over 12 months and the impact of Lantern on healthcare utilisation over 12 months. Patients from control sites will be matched to the patients who use the mobile app. Ethics and dissemination Ethics and human subject research approval were obtained. A data safety monitoring board is overseeing trial data and ethics. Results will be communicated to participating primary care practices, published and presented at clinical and scientific conferences. Trial registration number NCT03035019.
Traditional versus Theoretical Risk Measures

For thousands of years, mankind has understood that there is a tradeoff between risk and return. Yet the struggle to define the exact nature of the risk-return relationship continues. In the investment field, the Capital Asset Pricing Model (CAPM) is the best known traditional description of this relationship. Long before the CAPM came on the scene, however, analysts relied on experience and' common sense to quantify risk. An examination of the reltation between return and three different measures of risk-one traditional measure, the Value Line Safety Rank, and two theoretical measures, beta and standard deviation-reveals some surprising conclusions. These suggest that theoretical asset pricing models could be improved by considering the factors that contribute to the risk measures investors have trad'itionally used. Over the 12-year period 1974-85, safety rank exhibited the highest correlation with return, followed by standard deviation, with beta a distant third. This held true for both portfolios and individual stocks. For explaining individual stock returns, safety rank was three to four times more powerful than beta.
Culturing in serum-free culture medium on collagen type-I-coated plate increases expression of CD133 and retains original phenotype of HT-29 cancer stem cell

Background: A sub-population of tumor cells termed cancer stem cells (CSCs) has an important role in tumor initiation, progression, and recurrence. Selecting a suitable procedure for isolation and enrichment of CSCs is the biggest challenge in the study of CSCs. In the present study, the role of the combination of stem cell culture medium and collagen type-I was evaluated for successful isolation and enrichment of HT-29 CSCs. Materials and Methods: HT-29 cells were cultured in serum-containing medium (parental culture medium: Medium + 10% fetal bovine serum) and serum-free medium (stem cell culture medium); both on collagen-coated plates. Spheres forming ability and CD133 expression, as a potential marker of colorectal CSCs, were evaluated in two culture mediums. Results: The results show spheroids usually give rise completely within 15 days in the stem cell culture medium on the collagen-coated plate. CD133 expression in spheroid cells (84%) is extensively higher than in parental cells (25%). Moreover, relative to parental cells, spheroid cells were more radioresistance. Conclusion: Finding of this study suggested that CSCs derived from colon cancer cell line (HT-29) can be propagated and form colonospheres in serum-free culture medium on collagen type-I. According to maintenance of their original phenotype in these conditions, it seems serum-free culture medium on collagen type-I is a suitable way to drug screening of HT-29 CSCs.
Numerical Representations And User Behaviour In Social Networking Sites: Towards A Multi- Theoretical Research Framework

The new technological enhancements and the accessibility to varieties of online applications, enable users to collect personal data and perform self-evaluation through test, comparison and experimentation. The sparked interest in numbers and numbers as self-representative visualisations is prominent in social networking sites, which are the empirical setting for the present study. This paper sets out to establish a multi-theoretical framework which enables the investigation of emerging phenomena of the role of numbers in social networking sites. The proposed framework rests on three theoretical pillars: self-determination theory, heuristic decision making and behavioural economics. A discussion departs from these convictions to investigate user reactions and behaviour when faced with numerical representations in the SNS.
