The Car Resequencing Problem with Pull-Off Tables
2011
AbstractThe car sequencing problem determines sequences of different car models launched down a mixed- model assembly line. To avoid work overloads of workforce, car sequencing restricts the maximum occurrence of labor-intensive options, e.g., a sunroof, by applying sequencing rules. We consider this problem in a resequencing context, where a given number of buffers (denoted as pull-off tables) is available for rearranging a stirred sequence. The problem is formalized and suited solution procedures are developed. A lower bound and a dominance rule are introduced which both reduce the running time of our graph approach. Finally, a real-world resequencing setting is investigated.
Higher Socioeconomic Status Predicts Less Risk of Depression in Adolescence: Serial Mediating Roles of Social Support and Optimism.
2020
Family socioeconomic status (SES) is known to have a powerful influence on adolescent depression. However, the inner mechanisms underlying this association are unclear. Here, we explore this issue by testing the potential mediating roles of social support (interpersonal resource) and optimism (intrapersonal resource), based on the predictions of the Reserve Capacity Model (RCM). Participants were 652 adolescents (age range: 11-20 years old, Mage =14.55 years, SD = 1.82; 338 boys (51.80%)) from two junior and two senior high schools in Wuhan, China. They completed questionnaires measuring family SES, perceived social support, trait optimism, and depression. Results showed, as predicted, (1) …
Eco-epidemiology of tick- and rodent-borne pathogens in boreal forests
2017
Infectious diseases are amongst the ten major causes of human mortality worldwide, 60% of them being animal-borne. Variations of abiotic and biotic conditions are likely to modify the transmission of parasites and pathogens within reservoir species, and, as a consequence, alter the zoonotic risk for human. My thesis aims at elucidating the dynamics and mechanisms of the maintenance of ticks, tick-borne pathogens (TBPs) and the Puumala hantavirus (PUUV) in the reservoir host, the bank vole (Myodes glareolus, BV). In Northern Europe, tick-borne diseases are growing in importance to human because of the latitudinal expansion of the tick Ixodes ricinus. Field monitoring revealed that I. ricinus…
Association of emotional intelligence with resilience and work engagement in sports coaches
2021
Problem statement. Sports coaching is recognized as a stressful and challenging profession due to several different aspects such as organizational, performance, contextual, interpersonal, and intrapersonal stressors that coaches face. High level of work stress is a risk factor for decreased well-being at work. Sports coaches’ wellbeing not only matters to coaches themselves but plays a significant role in athlete performance and well-being as well. Approach. There is research evidence on sports coaches’ stress and burnout. There is, however, little knowledge on personal resources that enhance sports coach’s well-being at work. Therefore, studies that examine personal resource factors that f…
Oppilaiden kanssa vastuuta jakamassa : peruskoulun kahdeksannen luokan oppilaiden autonomian vahvistaminen englannin oppitunneilla samanaikaisopetuks…
2016
The aim of this ethnographic and autoethnographic research was to explore what kind of a learning culture existed in an 8th grade English class in a Finnish basic education school in the 2011-2012 academic year. The class was taught jointly by a subject teacher and a special education teacher. A teaching experiment was implemented with the support of co-teaching during which teachers aimed to strengthen students' learning autonomy: to support their active learning and help them act as responsible learners. The research data included participant observation notes, interviews of a subject teacher and students, and different kinds of documents produced by teachers and students during the imple…
Farming on the margins : Just transition and the resilience of peripheral farms
2022
Sustainability transition demands fundamental changes taking place at the farm system level. At the same time, many farms are operating on the verge of financial profitability, especially in geographically disadvantaged peripheral regions with a limited range of production opportunities. These observations raise concerns about the transition's justice aspects. Using the concept of resilience, we analysed farmers’ capacities for transformation in a peripheral context in Finland. The results from our farmer survey (n = 577) indicated that the regime exerts a strong cost-price squeeze on farmers, escaping of which is difficult also for farmers deliberately seeking new pathways beyond it. Due t…
Efecto pantalla y efecto Sísifo: dos fenómenos didácticos en la resolución de problemas por transferencia analógica
2014
Se presenta un estudio cualitativo, basado en entrevistas semi-estructuradas, de 2 casos que muestran dos fenomenos didacticos de interes en la resolucion de problemas por transferencia analogica. El primero muestra un ‘efecto pantalla’, en el cual el sujeto no puede acceder a la estructura de los problemas a partir de los enunciados. En el segundo caso, el sujeto no logra alcanzar un estado estable de comprension, a pesar de su avance, y por tanto acaba por retroceder a un estado de ausencia de conflicto cognitivo, pero indeseado desde el punto de vista didactico (‘efecto Sisifo’). Se discuten las posibles implicaciones didacticas de estos casos.
Synthesis, Electrochemistry, and Photophysics of Aza-BODIPY Porphyrin Dyes
2016
International audience; The synthesis of dyad and triad aza-BODIPY-porphyrin systems in two steps starting from an aryl-substituted aza-BODIPY chromophore is described. The properties of the resulting aza-BODIPY-porphyrin conjugates have been extensively investigated by means of electrochemistry, spectroelectrochemistry, and absorption/emission spectroscopy. Fluorescence measurements have revealed a dramatic loss of luminescence intensity, mainly due to competitive energy transfer and photoinduced electron transfer involving charge separation followed by recombination.
