Overall multiobjective optimization of construction projects scheduling using particle swarm
Authors: Elbeltagi Emad , Ammar Mohammed , Sanad Haytham , Kassab Moustafa 
Published: May 2016

Purpose
– Developing an optimized project schedule that considers all decision criteria represents a challenge for project managers. The purpose of this paper is to provide a multi-objectives overall optimization model for project scheduling considering time, cost, resources, and cash flow. This development aims to overcome the limitations of optimizing each objective at once resulting of non-overall optimized schedule.

Design/methodology/approach
– In this paper, a multi-objectives overall optimization model for project scheduling is developed using particle swarm optimization with a new evolutionary strategy based on the compromise solution of the Pareto-front. This model optimizes the most important decisions that affect a given project including: time, cost, resources, and cash flow. The study assumes each activity has different execution methods accompanied by different time, cost, cost distribution pattern, and multiple resource utilization schemes.

Findings
– Applying the developed model to schedule a real-life case study project proves that the proposed model is valid in modeling real-life construction projects and gives important results for schedulers and project managers. The proposed model is expected to help construction managers and decision makers in successfully completing the project on time and reduced budget by utilizing the available information and resources.

Originality/value
– The paper presented a novel model that has four main characteristics: it produces an optimized schedule considering time, cost, resources, and cash flow simultaneously; it incorporates a powerful particle swarm optimization technique to search for the optimum schedule; it applies multi-objectives optimization rather than single-objective and it uses a unique Pareto-compromise solution to drive the fitness calculations of the evolutionary process.
Emotion regulation during deception: an EEG study of imprisoned fraudsters
Authors: Krokoszinski Lars , Hosser Daniela 
Published: May 2016

Purpose
– The social interaction between a deceiver and the deceived opponent is a determining factor for deception that involves emotions. Hence, besides a great amount of cognitive control, a successful lie also requires the regulation of emotions, especially when deceiving somebody face-to-face. The purpose of this paper is to investigate emotion regulation processes in an interpersonal lying experiment and aimed to examine whether fraudsters have well-functioning emotion regulation strategies or show a lack of emotional processes when deceiving face-to-face.

Design/methodology/approach
– Imprisoned fraudsters (n=11), imprisoned violent offenders (n=10) and non-offenders (n=11) spontaneously deceived an interrogator in a face-to-face situation while the deceivers’ EEG was recorded.

Findings
– The results showed that a decrease of alpha activity in left dorsolateral prefrontal cortex (dlPFC) predicted a higher frequency of deceptive responses as well as less guilt about deceiving the interrogator. These findings suggest a pivotal role of the left dlPFC in emotion regulation during deception for fraudsters, violent offenders and non-offenders. Unlike violent offenders, fraudsters did not show differences in alpha activity of the dlPFC between truthful and deceptive responses, suggesting that fraudsters are better at emotion regulation while deceiving their opponents.

Originality/value
– This study emphasizes the recruitment of emotion regulation processes during deception. The results give first insight into the emotional processes underlying deception in fraudsters.

Purpose– The purpose of this paper is to provide a more robust understanding of how to deploy multiunit organizations’ dynamic capabilities (DCs) by examining the roles of embedded social (structural and relational) capital and knowledge archetype (exploitative and exploratory) learning.Design/methodology/approach– This study uses 315 multiunit samples and structural equation modeling to determine the relationships among the variables.Findings– The analysis reveals that, while embedded structural social capital exerts a positive influence on exploratory knowledge learning in multiunit organizations, embedded relational social capital exerts a positive influence on knowledge archetype (exploitative and exploratory) learning. Knowledge archetype (exploitative and exploratory) learning also positively influences DC deployment in multiunit organizations.Research limitations/implications– Few DCs studies have empirically examined the roles of embedded social (structural and relational) capital and knowledge archetype (exploitative and exploratory) learning in multiunit organizations. The results of this study address the failure of past theoretical perspectives on DCs to fully specify and verify the links between the roles of embedded social (structural and relational) capital and knowledge archetype (exploitative and exploratory) learning.Originality/value– This paper offers one practical trajectory for DC deployment in modern multiunit organizations and offers two contributions to the theoretical perspectives on DCs. First, it identifies the critical role of embedded social capital in enabling knowledge archetype learning and DC deployment, which had never been fully specified or verified in the DCs literature. Second, it identifies the importance of DCs’ deployment trajectory in multiunit organizations’ routine processes.

Summary

Artificial lights have become an integral and welcome part of our urban and peri‐urban environments. However, recent research has highlighted the potentially negative ecological consequences of ubiquitous artificial light. In particular, insects, especially moths, are expected to be negatively impacted by the presence of artificial lights. Previous research with light traps has shown a male‐biased attraction to light in moths.

In this study, we sought to determine whether street lights could limit moth dispersal and whether there was any sex bias in attraction to light. More specifically, we aimed to determine sex‐specific attraction radii for moths to street lights.

We tested these hypotheses by collecting moths for 2 years at an experimental set‐up. To estimate the attraction radii, we developed a Markov model and related it to the acquired data.

Utilizing multinomial statistics, we found that attraction rates to lights in the middle of the matrix were substantially lower than predicted by the null hypothesis of equal attraction level (0·44 times). With the Markov model, we estimated that a corner light was 2·77 times more attractive than a wing light with an equivalentre attraction radius of c. 23 m around each light. We found neither sexual differences in the attraction rate nor in the attraction radius of males and females. Since we captured three times more males than females, we conclude that sex ratios are representative of operational sex ratios or of different flight activities.

These results provide evidence for street lights to limit moth dispersal, and that they seem to act equally on male and female moths. Consequently, public lighting might divide a suitable landscape into many small habitats. Therefore, it is reasonable to assume (i) that public lighting near hedges and bushes or field margins reduces the quality of these important habitat structures and (ii) that public lighting may affect moth movement between patches.

AbstractIntroductionThe Surviving Sepsis Campaign guidelines recommend administration of appropriate antibiotics within 1 h in patients with severe sepsis, with two sets of blood cultures taken prior to administration.ObjectiveWe evaluated the effect of introducing a Sepsis Early Alert Tool (SEAT) in the ED. Outcomes were antibiotic timing, antibiotic choice and obtaining adequate blood cultures.MethodsA retrospective chart review compared consecutive severe sepsis presentations admitted to ICU via the ED during two equivalent 6 month periods before and after SEAT introduction.ResultsThe analyses included 55 patients before and 45 following SEAT introduction. The groups were similar in age, sex, triage category, sepsis source, Acute Physiology and Chronic Health Evaluation III scores and hospital mortality. The percentage receiving antibiotics within 60 min of triage increased from 24% (95% CI 13–37%) to 44% (95% CI 30–60%), P = 0.03. Median time from triage to first antibiotic was 105 (IQR 65–170) min and 85 (IQR 50–140) min before and after SEAT introduction, respectively, P = 0.15. Percentages receiving antibiotics within 60 min of first recognition of severe sepsis were 67% (95% CI 53–79%) and 71% (95% CI 56–84%) before and after SEAT introduction, P = 0.83. The percentage having two sets of blood cultures drawn prior to antibiotic administration increased from 18% (95% CI 9–34%) to 44% (95% CI 27–60%), P = 0.008. Appropriateness of antibiotics was 58% (95% CI 44–71%) and 75% (95% CI 60–87%) before and after SEAT implementation, P = 0.09.ConclusionThe introduction of a SEAT in the ED is associated with earlier recognition of severe sepsis and improvements in quality of care.

Published: May 2016

BackgroundThe aim of this study was to evaluate the diagnostic accuracy of integrated 18
F‐fluorodeoxyglucose positron emission tomography/computed tomography (FDG‐PET/CT) in hilar and mediastinal lymph node (HMLN) staging of non‐small cell lung cancer (NSCLC), and to investigate potential risk factors for false‐negative and false‐positive HMLN metastases.MethodsWe examined the data of 388 surgically resected NSCLC patients preoperatively staged by integrated FDG‐PET/CT. Risk factors for false‐negative and false‐positive HMLN metastases were analyzed using univariate and multivariate analyses of clinicopathological factors.ResultsThe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of integrated FDG‐PET/CT in detecting HMLN metastases were 47.4%, 91.0%, 56.3%, 87.7%, and 82.5%, respectively. On multivariate analysis, the maximum standardized uptake value (SUVmax) of the tumor (P = 0.042), adenocarcinoma (P = 0.003), and tumor size (P = 0.017) were risk factors for false‐negative HMLN metastases, and history of lung disease (P = 0.006) and tumor location (central; P = 0.025) were risk factors for false‐positive HMLN metastases.ConclusionsThe present study identified risk factors for false‐negative and false‐positive HMLN metastases in NSCLC patients staged by preoperative integrated FDG‐PET/CT. These findings would be helpful in selecting appropriate candidates for mediastinoscopy or endobronchial ultrasound‐guided transbronchial needle aspiration.

BackgroundAlcoholic hepatitis (AH) is a major cause of liver‐related hospitalization. The profile, treatment patterns, and outcomes of subjects admitted for AH in routine clinical practice are unknown. Also, it is not known whether these are changing over time. This study is thus aimed to identify temporal trends in hospitalization rates, clinical characteristics, treatment patterns, and outcomes of subjects admitted for AH in a routine clinical setting.MethodsA retrospective analysis of adults admitted for AH from 2000 to 2011 was performed using an anonymized EMR database of patient‐level data from 169 U.S. medical centers.Results(i) Epidemiology: The proportion of baby boomers admitted for AH increased from 2000 to 2011 (26 to 31%, p < 0.0001). (ii) Clinical: The median Model for End‐Stage Liver Disease (MELD) score increased over time from 12 to 14 (p = 0.0014) driven mainly by increased international normalized ratio (1.2 to 1.4, p < 0.0001). The median Charlson Comorbidity Index increased from 0 to 1 (p < 0.0001) with increased diabetes, chronic obstructive pulmonary disease, and heart disease. (iii) Complications: The following increased from 2001 to 2011: Gastrointestinal bleed—7 to 10% (p = 0.03); hepatic encephalopathy—7 to 13% (p < 0.0001); hepatorenal syndrome—1.8 to 2.8% (p = 0.0003); sepsis—0 to 6% (p < 0.0001); and pancreatitis—11 to 16% (p = 0.0061). (iv) Treatment patterns and mortality: Eight to 9% of subjects received steroids while pentoxifylline use increased to 2.2%. In those with MELD ≥ 22, mortality remained between 19 and 20% and only steroids modestly improved survival in this subset.ConclusionsSevere AH continues to have a high mortality. The severity and comorbidities and complications associated with AH have worsened. Drug therapy remains suboptimal.

Abstract
A recent invader to North America, emerald ash borer Agrilus planipennis Fairmaire (Buprestidae), is expanding its western range into new habitats. We examined how site factors affect the emergence and damage caused by this beetle on the western edge of its contiguous population in eastern Wisconsin, U.S.A. We characterized forest structure and quantified signs and symptoms of A. planipennis from 2010 to 2013.
We evaluated the potential for establishment of three host‐specific parasitic Hymenoptera, released as biological control agents of A. planipennis. During June to September 2011, we conducted releases of 1500 Oobius agrili Zhang and Huang (Encyrtidae), 1900 Spathius agrili Yang (Braconidae) and 2700 Tetrastichus planipennisi Yang (Eulophidae) at the same location.
Signs and symptoms of A. planipennis increased in abundance during the present study. Emergence of A. planipennis was greater in larger diameter trees and in subplots with more ash trees. More epicormic shoots were on the upper halves of trees in subplots with a higher percentage of ash. Fraxinus nigra exhibited a higher incidence of ruptured bark than Fraxinus pennsylvanica.
In January 2013, we felled four infested ash trees and censused insect emergence from the entire trees. We recovered 441 A. planipennis, 41 T. planipennisi and no other released parasitoids.
These results suggest that, of these three parasitoids, T. planipennisi has the highest likelihood of contributing to biological control in Wisconsin, although ash mortality will proceed rapidly and likely supersede the effects of the parasitoids. The best opportunity for introduced parasitoids to benefit Wisconsin may arise in post‐outbreak, recovering forests.

ProblemCyclosporin A (CYS A) is an immunosuppressant agent administered in autoimmune diseases, and its use during pregnancy and lactation is a debated topic.Method of studyThe demographic characteristics, the activity of the underlying disease, and the onset of fetal–maternal complications have been investigated in 21 consecutive patients (2 RA, 14 SLE, 2 PA, 1 SjS, 1 DM, 1 Churg–Strauss vasculitis), treated with CYS A throughout 29 gestations. A subanalysis of the SLE group was performed.ResultsWe recorded a live birth rate of 86.2%. The median gestational age at birth was 38.2 weeks. The prevalence of maternal–fetal complications showed no differences with general population. Disease flares appeared in 4% of patients during gestation and in 12% during puerperium.ConclusionWe found no evidence justifying the suspension of CYS A when a pregnancy occurs. The drug does not appear to promote maternal–fetal complications and should be continued in patients who benefit from therapy. Data regarding breast‐feeding during therapy are still scarce, but no evidence of toxicity has emerged.
Hidden Markov Latent Variable Models with Multivariate Longitudinal Data

Summary
Cocaine addiction is chronic and persistent, and has become a major social and health problem in many countries. Existing studies have shown that cocaine addicts often undergo episodic periods of addiction to, moderate dependence on, or swearing off cocaine. Given its reversible feature, cocaine use can be formulated as a stochastic process that transits from one state to another, while the impacts of various factors, such as treatment received and individuals’ psychological problems on cocaine use, may vary across states. This article develops a hidden Markov latent variable model to study multivariate longitudinal data concerning cocaine use from a California Civil Addict Program. The proposed model generalizes conventional latent variable models to allow bidirectional transition between cocaine-addiction states and conventional hidden Markov models to allow latent variables and their dynamic interrelationship. We develop a maximum-likelihood approach, along with a Monte Carlo expectation conditional maximization (MCECM) algorithm, to conduct parameter estimation. The asymptotic properties of the parameter estimates and statistics for testing the heterogeneity of model parameters are investigated. The finite sample performance of the proposed methodology is demonstrated by simulation studies. The application to cocaine use study provides insights into the prevention of cocaine use.

AbstractObjectiveQuestions have been raised about potential risks of prenatal exposure to mercury from amalgam fillings during pregnancy. The aim of this study was to assess possible associations between exposure to amalgam fillings in pregnant women participating in a large cohort study and adverse pregnancy outcome.MethodsIn the Norwegian Mother and Child Cohort Study (MoBa), a valid information about the number of teeth with amalgam fillings and dental treatment, including new amalgam fillings placed or removed during pregnancy, was available from 69 474 pregnancies. The information was obtained from two questionnaires sent to the women at 17 and 30 weeks of pregnancy, and the data were linked to the Medical Birth Registry of Norway. Logistic regression was used to estimate the odds ratio (OR) and 95% confidence intervals (95%CI) as a measure of association between pregnancy outcome and prenatal exposure to amalgam fillings.ResultsLogistic regression models, including mothers′ age, education,BMI, parity, smoking during pregnancy, and alcohol consumption during pregnancy revealed no significant associations between the number of teeth with amalgam fillings and early preterm delivery, late preterm delivery, low birthweight, malformation or stillbirth.ConclusionsWe found no evidence for serious perinatal consequences of maternal exposure to amalgam fillings during pregnancy.

AbstractObjectivesDentistry is among the occupations involving chronic exposure to ionizing radiation. Although several cohort studies on medical radiation workers have been conducted in some countries, only a few epidemiological studies on dentists have been performed to examine occupational radiation exposure worldwide. The aim of this study was to investigate occupational characteristics and radiation exposures in South Korean dentists.MethodsA total of 658 dentists were surveyed from April 2012 to May 2013, and survey data were linked with dosimetry data from the National Dose Registry. Multiple linear regression analysis was used to identify the relationship between demographic or occupational factors and individual radiation doses.ResultsOf the dentists sampled, 78% were men, 51% were younger than age 40, and 61% began employment after 2000. The most frequent procedures performed by dentists were panoramic radiography, followed by intraoral and portable dental radiography. Male dentists were more frequently involved in radiation procedures, and a higher proportion of male than female dentists wore a lead apron for diagnostic radiology. The average annual effective dose was 0.18 mSv for male and 0.13 mSv for female dentists. Female dentists working in provincial areas had significantly higher average annual and cumulative effective doses than those in metropolitan areas. The cumulative effective doses were significantly greater for older dentists, those who entered the field in the 1990s, and those with longer employment duration.ConclusionsOur findings provided detailed information on work practices, number of procedures performed on a weekly basis, and occupational radiation doses, which enabled in‐depth evaluation of occupational radiation exposure and work status among dentists.

Published: May 2016

AbstractParenting strategies involving psychological control are associated with increased adjustment problems in children. However, no research has examined the extent to which culture and psychological control predict children's stress physiology. We examine cultural differences in maternal psychological control and its associations with children's cortisol. Chinese (N = 59) and American (N = 45) mother‐child dyads participated in the study. Mothers reported on psychological control. Children's cortisol was collected during a stressor and two indices of Area Under the Curve (AUC) were computed: AUCg which accounts for total output, and AUCi, which captures reactivity. Results indicate that Chinese mothers reported higher levels of psychological control and Chinese children had higher levels of AUCg than their American counterparts. Across both cultures, psychological control was significantly associated with increased cortisol levels as indexed by AUCg. There were no associations for AUCi. Finally, mediation analyses demonstrated that psychological control fully explained cultural differences in children's cortisol stress response as indexed by AUCg.
