BRT in the Philippines: A Solution to Manila and Cebu Traffic Problems?
2019
Abstract Bus Rapid Transit (BRT), where buses run on dedicated roads at high frequency, almost in a metrorail manner, has been adopted as a backbone of urban mobility in the cities of many developing countries. Originally developed in South America (Curitiba, Brazil and Bogotá, Colombia), it has entered Asia with force, from Indonesia (Jakarta’s Transjakarta) to India and China. In the case of the Philippines, where intercity bus transportation is widely used due to the current lack of a railway network, city traffic, especially in Manila, is heavily congested, partly due to a high number of city buses running half-empty, the small proportion of road space relative to the vehicle population…
Are long-haul truck drivers unusually alert? A comparison with long-haul airline pilots.
2020
Abstract Background Recent studies suggest heavy vehicle drivers self-estimate their sleepiness unexpectedly low during night duties. The present study compared sleepiness ratings of long-haul truck drivers with those of long-haul airline pilots during night and non-night duties. In addition, the correspondence between self-rated manifest and predicted latent sleepiness was examined in the two groups. Methods Twenty-two drivers and 33 pilots participated. Their working hours, sleep, on-duty sleepiness, and use of sleepiness countermeasures were measured in naturalistic conditions. Predictions of latent sleepiness were based on the measurements of working hours and sleep using the Sleep/Wake…
Accumulation of sleep loss among shift-working truck drivers.
2021
Sleep loss is known to contribute to road traffic accidents. Professional drivers are vulnerable to curtailment of sleep due to long driving bouts and shift work. To fill in the gap in the literature related to the buildup of sleep loss in irregular shift systems, we recorded the sleep and working hours of 47 shift-working long-haul truck drivers during a two-week period. Sleep (time in bed) was verified by actigraphy and sleep logs. Sleepiness was measured using the Karolinska Sleepiness Scale (KSS). Individual sleep need was based on self-assessments. We examined the accumulated sleep versus self-reported sleep need across the study period, using midnights as points of observation, and th…
La movilidad geográfica de la población extranjera en España : un fenómeno emergente
2002
En este articulo se analizan, a partir de los microdatos de la Estadística de Variaciones Residenciales del período 1988-2001, las características demográficas y los patrones espaciales de las migraciones internas de la población extranjera en España. Entre los principales resultados de este trabajoso destacan: una mayor intensidad migratoria de los extranjeros con relación a los españoles; los extranjeros muestran una gran diversidad de patrones migratorios cuando se consideran diferentes nacionalidades. En este contexto, algunas provincias se caracterizan por ser centros difusores de algunas nacionalidades, como Madrid de los latinoamericanos y Almería de los africanos, y otras son recept…
Phytoestrogens increase the capacity of serum to stimulate prostacyclin release in human endothelial cells
2003
Both the estrogen receptor (ER) alpha and beta isoforms are expressed in the endothelium. The ER beta has been assigned a crucial role in normal vascular wall function. Prostacyclin has been ascribed a beneficial effect on vessel wall physiology. Isoflavones bind with higher affinity to ER beta. We investigated the hypothesis that their administration to postmenopausal women can promote endothelial prostacyclin production.Twenty-five healthy postmenopausal women with mild climacteric symptoms received capsules containing 55 mg/day isoflavones derived from soy and red clover for 6 months. Cultured human umbilical vein endothelial cells (HUVECs) were exposed for 24 h to serum collected before…
How should vaccination services be planned, organized, and managed? Results from a survey on the Italian vaccination services
2019
Background. Quality improvement is an increasingly recognized approach to maximize service effectiveness and minimize costs in public health. However, the Italian law never provided for the institutional accreditation of vaccination services. Furthermore, a recently approved law added six more compulsory vaccinations to the original four, which has led to a considerable increase in vaccination efforts, without any previous resources evaluation. The aim of the study was to investigate structural, organizational and managerial characteristics of the Italian vaccination services, in order to suggest the adoption of adequate quality standards. Study design. A survey involving the representative…
An Open-Label Phase II Study Evaluating the Safety and Efficacy of Ramucirumab Combined With mFOLFOX-6 as First-Line Therapy for Metastatic Colorecta…
2014
Abstract Author Summary Background. Vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) are believed to mediate angiogenesis in colorectal cancer (CRC). Ramucirumab (RAM; IMC-1121B) is a human IgG1 monoclonal antibody that inhibits VEGF ligand binding to VEGFR-2, inhibiting VEGFR-2 activation and signaling. Methods. Patients with metastatic CRC, Eastern Cooperative Oncology Group performance status 0–1, and adequate organ function who had not received chemotherapy for metastatic disease received RAM and the modified FOLFOX-6 regimen every 2 weeks. Endpoints included progression-free survival (PFS), objective response rate, overall survival, and safety. The sample size wa…
A graph colouring model for assigning a heterogeneous workforce to a given schedule
1996
Abstract We analyze a heterogeneous workforce assignment problem in which the minimum number of workers required to carry out a machine load plan is calculated. The problem is formulated as a restricted vertex colouring problem and a branch and bound algorithm is presented. The special characteristics of the graph to be coloured allow an efficient implementation of the branch and bound. Computational results show that the algorithm can solve problems of 50 activities, 5, 10 and 15 machines and between 2 to 15 different types of workers in just a few seconds.
Burnout syndrome among psychiatric trainees in 22 countries: Risk increased by long working hours, lack of supervision, and psychiatry not being firs…
2016
AbstractBackgroundPostgraduate medical trainees experience high rates of burnout, but evidence regarding psychiatric trainees is missing. We aim to determine burnout rates among psychiatric trainees, and identify individual, educational and work-related factors associated with severe burnout.MethodsIn an online survey psychiatric trainees from 22 countries were asked to complete the Maslach Burnout Inventory (MBI-GS) and provide information on individual, educational and work-related parameters. Linear mixed models were used to predict the MBI-GS scores, and a generalized linear mixed model to predict severe burnout.ResultsThis is the largest study on burnout and training conditions among p…
Pedagogy-related tensions in flexibly scheduled early childhood education and care
2020
In flexibly scheduled early childhood education and care (ECEC), the timing of care depends on parents’ non-standard working hours. Multiple individual schedules and care times in a child group may cause irregularity in a child’s daily structures, and a child may miss a standard hour’s activities that are led by teachers with a pedagogical education. In this context, the significance and definition of pedagogy is vague and tensional. This study aimed at disclosing discursive tensions related to pedagogy in flexibly scheduled ECEC constructed in interviews by Finnish teachers and childcare nurses (n = 31). The analysis of the interview data followed the principles of discursive psychology. C…
