A decision tree prediction model for a short-term outcome of delirium in patients with advanced cancer receiving pharmacological interventions: A secondary analysis of a multicenter and prospective observational study (Phase-R)

Abstract Objective There is no widely used prognostic model for delirium in patients with advanced cancer. The present study aimed to develop a decision tree prediction model for a short-term outcome. Method This is a secondary analysis of a multicenter and prospective observational study conducted at 9 psycho-oncology consultation services and 14 inpatient palliative care units in Japan. We used records of patients with advanced cancer receiving pharmacological interventions with a baseline Delirium Rating Scale Revised-98 (DRS-R98) severity score of ≥10. A DRS-R98 severity score of <10 on day 3 was defined as the study outcome. The dataset was randomly split into the training and test dataset. A decision tree model was developed using the training dataset and potential predictors. The area under the curve (AUC) of the receiver operating characteristic curve was measured both in 5-fold cross-validation and in the independent test dataset. Finally, the model was visualized using the whole dataset. Results Altogether, 668 records were included, of which 141 had a DRS-R98 severity score of <10 on day 3. The model achieved an average AUC of 0.698 in 5-fold cross-validation and 0.718 (95% confidence interval, 0.627–0.810) in the test dataset. The baseline DRS-R98 severity score (cutoff of 15), hypoxia, and dehydration were the important predictors, in this order. Significance of results We developed an easy-to-use prediction model for the short-term outcome of delirium in patients with advanced cancer receiving pharmacological interventions. The baseline severity of delirium and precipitating factors of delirium were important for prediction.
Antecedent of Consumer Impulsive Buying Behavior: A perspective of Developing Nation

Impulsive buying concerns the unplanned decision made by consumers before buying any items. Recognizing the factors that influence consumer’s impulsive buying behavior aids retail stores to understand consumer’s decision-making process and accordingly help them design and develop courses of action. However, few studies have only been conducted in this area in context of developing nation. The purpose of this study is to identify the factors that influence impulsive buying behavior and the vital factor amongst them. After collecting 141 valid responses, the study validated the proposed conceptual model using structural equation model. AMOS 26 was used to analyze the data. Data were analyzed in two-fold: Measurement model and structural model. Three items were covaried to reach the optimal model fit revealing hedonic value and shopping enjoyment significant influence on impulsive buying. This research contributes to the knowledge about the relationship among hedonic value, marketing stimuli, shopping enjoyment and social interaction with impulsive buying behavior.
Irregular Wave Forces on Monopile Foundations: Effect of Full Nonlinearity and Bed Slope

Forces on a monopile from a nonlinear irregular unidirectional wave model are investigated. Two seabed profiles of different slopes are considered. Morison’s equation is used to investigate the forcing from fully nonlinear irregular waves and to compare the results with those obtained from linear wave theory and with stream function wave theory. The latter of these theories is only valid on a flat bed. The three predictions of wave forces are compared and the influence of the bed slope is investigated. Force-profiles of two selected waves from the irregular wave train are further compared with the corresponding force-profiles from stream function theory. The results suggest that the nonlinear irregular waves give rise to larger extreme wave forces than those predicted by linear theory and that a steeper bed slope increases the wave forces both for linear and nonlinear waves. It is further found that stream function theory in some cases underestimate the wave forces acting on the monopile.Copyright © 2011 by ASME
Joint Transmit Antenna Selection and Artificial Noise for Security in MIMO Wiretap Channels

In this paper, We propose a effective method which joint transmit antenna selection (TAS) and artificial noise to promote communication security in MIMO wiretap channels. Firstly, based on TAS protocol, the transmitter selects one antenna (the max-antenna) that maximizes the instantaneous signal-noise-ratio (SNR) at the receiver. Secondly, the transmitter uses the max-antenna to transmit valid data, and simultaneously, uses the remaining antennas to transmit artificial noise which only affects the eavesdropper. Thirdly, The receiver and the eavesdropper employ maximal-ratio combining (MRC) to combine the received signals. We focus on the practical scenario where the transmitter does not have any channel state information (CSI) of the eavesdroppers channel. Our joint TAS and artificial noise scheme (TAS-AN) have low complexity, and can enhance the systems security. The numerical simulation results verify our analysis.
Conflict between Designers and Marketers: A Study of Graphic Designers in New Zealand

Good relationships between marketing and design are important for marketing success. However, good relationships do not always occur. This study therefore aims to assess the interface between graphic designers and marketers in New Zealand and to determine how the relationship can be improved in the future. The study has found that, generally, the level of integration and quality of the relationship between graphic designers and marketers is good and that the level of conflict is relatively low. The main sources of conflict are issues relating to time and cost constraints, poor communications and a lack of understanding and respect for each other. The main ways in which the relationship can be improved are through better communications, through the two functions learning more about each other's discipline and through closer cooperation.
Experimental and Numerical Investigation of the Influence of Rotor Blades on Hot Gas Ingestion Into the Upstream Cavity of an Axial Turbine Stage

The phenomenon of hot gas ingestion through turbine rim seals is experimentally and numerically investigated for a complete stage with nozzle guide vanes and uncooled helicopter turbine rotor blades.In the experimental part, two different geometrical rim seal configurations are examined: 1. a simple axial gap between rotor and stator disk and 2. an axial gap between the rotor disk and a rim seal lip at the periphery of the stator disk. The results obtained are compared to experiments carried out for the same geometry but without rotor blades.The influence of the presence of rotor blades on hot gas ingestion is examined for different parameters such as nondimensional seal flow rate, Reynolds number in the turbine annulus and rotational speed. For the determination of the sealing efficiency measurements of carbon dioxide gas concentration are carried out in the wheelspace. The static pressure distribution in the cavity is measured by means of pressure taps at the stator disk.It is shown that for configuration 1 the presence of rotor blades causes a considerable drop in sealing efficiency whereas for configuration 2 the sealing efficiency increases significantly.In the numerical part results of three-dimensional unsteady CFD calculations for configuration 2 are compared to steady calculations for the same configuration without blades. Predictions of hot gas ingestion and carbon dioxide gas concentration in the hub region and inside the cavity are presented. Special emphasis is put on unsteady effects arising from rotor movement.A local ingestion zone rotating at approximately half rotor speed is numerically predicted. As indicated by the experimental results the rotor blades have a positive influence on the predicted sealing efficiency.Copyright © 2000 by ASME
OPTIMAL DESIGN OF PUBLIC BUS SERVICE WITH DEMAND EQUILIBRIUM

Analytical models are developed to optimize bus service with their demand characteristics. The optimizing bus services design options are analyzed in this paper, while route spacing and headway are included with or without vehicle capacity constraints. Optimal levels of these variables are obtained analytically for the objective functions of profit maximization. The analysis uses an equilibrium framework with transient ridership sensitive to the level of service provided by the bus system. The major results consist of closed-form solutions for the optimal area operating policies that are dependent upon local conditions (vehicle capacity constraints) and coefficients of the demand.
The Energy Yield of Roof Mounted Wind Turbines

The roof is a possible site for small wind turbines. This is a new but more and more accepted idea. Several Dutch companies in close cooperation with the Section Wind Energy of Delft University of Technology are busy with the design of small roof wind turbines at the moment. The important flow features for a wind turbine on the roof however are unknown. The common wind engineering knowledge is only focussed on extreme wind speeds in order to have a safe building. So, models to calculate the flow features on the roof, important for a wind turbine, have to be developed. This paper gives a first attempt to describe the flow features and guidelines necessary for siting of small wind turbines on the roof. They concern: the desirable height above the roof, the change of the undisturbed wind to the wind speed above the roof and the probability distribution of the wind speed above the roof. With use of the guidelines three example calculations are given to assist the reader in the calculation procedure.

Male Sex Workers Selling Physical Sex during the COVID-19 Pandemic in Portugal: Motives, Safer Sex Practices, and Social Vulnerabilities

The purpose of this research was to assess the motives, safer sex practices, and vulnerabilities of male sex workers who sold physical sex during the COVID-19 pandemic. This study used a mixed strategy, utilizing purposive sampling techniques to conduct 13 online surveys with male sex workers working in Portugal during the COVID-19 pandemic. Participants were aged between 23 and 47 years old and mostly provided their services to other men. Additionally, half of the participants were immigrants. Participants mentioned paying for essential expenses (rent, food, phone, etc.), having money for day-to-day expenses, wanting to, and enjoying it, as their main motives for engaging in sex work. Regarding sexual practices, 3 to 11 participants did not always or did not consistently use condoms during penetrative sex with their clients. Thematic analysis was used to identify the following repeated patterns of meaning regarding COVID-19-related vulnerabilities, encompassing a loss of clients and income, increased work availability, price reductions and negotiation difficulties, emotional functioning, health care access, safer sex negotiations, age, and immigration status. The findings serve as a basis for recommendations regarding social policies aimed at male sex workers who sell physical sex in Portugal.
From the margins to the NICE guidelines: British clinical psychology and the development of cognitive behaviour therapy for psychosis, 1982–2002

Although histories of cognitive behaviour therapy have begun to appear, their use with people with psychosis diagnoses has received relatively little attention. In this article, we elucidate the conditions of possibility for the emergence of cognitive behaviour therapy for psychosis (CBTp) in England between 1982 and 2002. We present an analysis of policy documents, research publications and books, participant observation, and interviews with a group of leading researchers and senior policy actors. Informed by Derksen and Beaulieu’s articulation of social technologies, we show how CBTp was developed and stabilised through the work of a variety of overlapping informal, academic, clinical, professional, and policy networks. The profession of clinical psychology played a key role in this development, successfully challenging the traditional ‘division of labour’ where psychologists focused on ‘neurosis’ and left ‘psychosis’ to psychiatry. Following Abbott's systems approach to professions, we identify a number of historical factors that created a jurisdictional vulnerability for psychiatry while strengthening the jurisdictional legitimacy of clinical psychology in providing psychological therapies to service users with psychosis diagnoses. The National Institute for Health and Clinical Excellence played a significant role in adjudicating jurisdictional legitimacy, and its 2002 schizophrenia guidelines, recommending the use of psychological therapies, marked a radical departure from the psychiatric consensus. Our analysis may be of wider interest in its focus on social technologies in a context of jurisdictional contestation. We discuss the implications of our study for the field of mental health and for the relationship between clinical psychology and psychiatry.
Priceless time – The UHNWI's most precious possession: implications for international marketing theory and practice

PurposeTraditionally, international luxury marketing highlights possible disparities of cultural and value perception. The context-specific nature of traditional international luxury marketing, which ranges from educational and cultural to financial and offering-based variations, delivers little guidance to managers in the field regarding how to cater best to their highest target segment. The study aims to exemplify the relevance of global consumer culture (GCC) theory for the ultra-high-net-worth-individual (UHNWI) context. The authors' research on UHNWIs maps the DNA, so to speak, of the UHNWI customer experience (CX) by determining what drives UHNWI purchasing behavior independent of background – in other words, what matters most to this exclusive consumer segment.Design/methodology/approachInterviewing 15 UHNWIs using a means-end approach and incorporating the emerging consensus technique (ECT), the authors explored the CX of UHNWIs leading to their purchasing decisions.FindingsThe authors' analysis reveals the three main constituents of the UHNWI CX: the value of time, expectation mismanagement and the utilitarian nature of luxury. The findings highlight that UHNWIs see traditional luxury as a necessity rather than a luxury and value different factors, such as time, much more highly. The findings highlight the UHNWI homogenous nature, connecting GCC to purchasing behavior.Practical implicationsThe authors' study delivers empirical evidence of what matters most to the UHNWI segment and drives their purchasing behavior. The authors are questioning existing luxury segmentation strategies and lay out a clear guidance on how to design and deliver effective and efficient marketing, sales and communications strategies for the elusive UHNWI segment. The research highlights that it is the experience and the three main dimensions, namely expectation mismanagement, luxury as a utility and the value of time. Following UHNWI CX DNA framework will allow luxury companies to build their marketing and client acquisition efforts on a solid understanding of what matters most to the UHNWI target segment.Originality/valueThe study highlights the commonalities of UHNWIs in terms of what matters most to them. Based on this, the authors develop a UHNWI CX DNA. The authors propose that traditional context-specific differences upheld by international marketing researchers might not apply to the UHNWI segment. The authors deliver evidence that UHNWI are an excellent example of the applicability of GCC theory. The only difference in perception the authors noticed was between CX evaluations of self-made UHNWIs and those who inherited their wealth in an otherwise homogenous segment.
Identifying management research priorities

An agenda for management research can be set by the academic community with more or less input from practising managers. The purpose of this note is to describe a model for collecting, structuring and analysing practitioner views of what should be the priorities for construction management research. A meeting with construction sector participants gave rise to proposals that were consolidated into 20 management themes. Next, a questionnaire sent to 260 individuals received 140 responses where these themes had been ranked and the strength of recent industry development for each theme assessed. Results show that high priority was assigned to leadership issues and identification of customer needs. The process should be possible to replicate abroad, although cultural differences are expected to influence priorities.

Efficiency of nonstandard and high contact ratio involute spur gears

A power loss prediction was extended to include involute spur gears of nonstandard proportions. The method is used to analyze the effects of modified addendum, tooth thickness, and gear center distance in addition to the parameters previously considered which included gear diameter, pitch, pressure angle, face width, oil viscosity, speed, and torque. Particular emphasis was placed on high contact ratio gearing (contact ratios greater than two). Despite their higher sliding velocities, high contact ratio gears are designed to levels of efficiency comparable to those of conventional gears while retaining their advantages through proper selection of gear geometry.
Development of a High Gain Observer for In-Line Monitoring of Sublimation in Vial Freeze Drying

In-line monitoring of the primary drying of the lyophilization process of a pharmaceutical product in vials is addressed in this article. A soft sensor (observer) based on the high gain concept is designed to this purpose. The proposed observer combines the physical measure of the frozen product temperature at the bottom of the vial with a simplified mathematical model of the process. This approach allows the continuous estimation of the entire temperature profile of the product and the monitoring of the state of progression of the primary drying phase. The main issues arising in the design of this observer are discussed. A detailed and experimentally validated mono-dimensional model is used as a source of measured data, in order to compare and validate by means of numerical simulations the results provided by the soft sensor. Finally, the performance of the high gain observer is compared with that of a Kalman filter–based observer previously proposed for the same process, evidencing the advantages of the high gain approach.
An analysis of mobile phone use by car drivers in Greece

The objective of this study was to investigate the rate of mobile phone use among car drivers in Greece and its association with drivers' characteristics and other parameters. Data collected through an observation survey were used in a binary logistic regression model which highlighted the explanatory factors of using a mobile phone while driving. Pseudo-elasticities quantified the impact of each variable on mobile use. The observation survey showed that 9% of car drivers in Greece use a hand-held mobile phone. The dependent variable with the greatest impact was the driver's age being between 16 and 24 years. The results will assist the development of targeted intervention strategies to decrease mobile phone use while driving and will act as a baseline against which the effect of these interventions can be measured. Education and information campaigns have a key role in increasing public awareness regarding the risks involved in using a mobile phone in traffic.
Low speed piezoelectric optical microscanner actuated by piezoelectric microcantilevers using LaNiO3 buffered Pb(Zr,Ti)O3 thin film

We have developed piezoelectric optical microscanners for low speed scanning actuated by piezoelectric microcantilevers using LaNiO3 (LNO) buffered Pb(Zr,Ti)O3 (PZT) thin films. The microscanners were fabricated from multilayers of Pt/LNO/PZT/LNO/Pt/Ti/ SiO2 deposited on silicon on insulator (SOI) wafers through a microelectromechanical system (MEMS) microfabrication process. The microcantilevers were also fabricated through the same microfabrication process. Using the microcantilevers, we investigated the actuation conditions for the microscanners. We found that the microscanners actuated under non-resonant AC actuation need DC bias application to realize the mirror rotation. Application of 10 V of DC bias resulted in a linear increase in the mirror rotation angle with the amplitude of the AC actuation voltage. The mechanical half rotation angle of the mirror reached 5.3° under actuation by an AC voltage of 20 Vpp–30 Hz and a DC bias of 10 V.
