Does higher technical efficiency induce a higher service level? A paradox association in the context of port operations
2020
Abstract Researchers and practitioners are benchmarking technical efficiency of ports and exploring the drivers of high efficiency. Paradoxically, this study argues that high technical efficiency (TE = 1) is not always essential, but an optimal level needs to be achieved while balancing the port service level. This study applies data envelopment analysis (DEA) and free disposal hull (FDH) methods to perform efficiency rankings of 38 container terminals from 17 different ports in 12 Asian countries. Four terminals are technically efficient (TE = 1) in all frontier approaches, thereof one Bangladeshi, one Chinese, one Indian and one Vietnamese. Furthermore, this study presents a case study co…
The potential impact of Brexit on Ireland's demand for shipping services to continental Europe
2018
Abstract Ireland, as an island nation, has historically relied on the UK landbridge to export and import its goods to and from Europe. This provides a fast, reliable and secure service along the UK landbridge route relative to the more economical and less frequent direct continental route. However, the relative competitiveness of maritime services along both routes may be significantly influenced by the UK exit from the European Union or Brexit. This paper aims to understand the potential impact of Brexit on maritime freight transport demand from Ireland to continental Europe for export trade shipments. Based on data collected from an efficient stated preference (SP) experiment, discrete ch…
The last-mile vehicle routing problem with delivery options
2021
AbstractThe ongoing rise in e-commerce comes along with an increasing number of first-time delivery failures due to the absence of the customer at the delivery location. Failed deliveries result in rework which in turn has a large impact on the carriers’ delivery cost. In the classical vehicle routing problem (VRP) with time windows, each customer request has only one location and one time window describing where and when shipments need to be delivered. In contrast, we introduce and analyze the vehicle routing problem with delivery options (VRPDO), in which some requests can be shipped to alternative locations with possibly different time windows. Furthermore, customers may prefer some deli…
‘Drawing’ conclusions : Irish primary school children’s understanding of physical education and physical activity opportunities outside of school
2017
This study explores the relationship between primary school physical education and physical activity as sites for the practice of physical activity of Irish primary school children. Understanding how children make connections between physical activity sites is important in shaping physical education experiences that promote lifelong participation. Children’s (aged 8–11) awareness, knowledge, and understanding of physical activity and physical education were examined using participatory methods of ‘draw and write’ ( n = 135) and focus group interviews ( n = 34). In Phase 1, data collection focused on physical activity, while Phase 2 focused on physical education and connections between phys…
Cribra orbitalia as a potential indicator of childhood stress: Evidence from paleopathology, stable C, N, and O isotopes, and trace element concentra…
2016
Cribra orbitalia (CO), or porotic hyperostosis (PH) of the orbital roof, is one of the most common pathological conditions found in archaeological subadult skeletal remains. Reaching frequencies higher than 50% in many prehistoric samples, CO has been generally attributed to a variety of factors including malnutrition (e.g., megaloblastic anemia) and parasitism. In this study, we tested the relationship between CO, trace element concentrations, and stable isotope values (δ13C, δ15N, δ18O) in subadult skeletons from a 17th to 18th century cemetery in the historic town of Jēkabpils, Latvia. A total of 28 subadults were examined, seven of which (25%) showed evidence of CO. Bioarchaeological ev…
English pronunciation teaching at different educational levels: Insights into teachers’ perceptions and actions
2016
The aim of the present paper is to reflect upon the place of pronunciation in English as a foreign language (EFL) teaching at different educational levels in Poland. To collect the data, an on-line survey was conducted among EFL professionals teaching at primary, lower secondary, and higher secondary schools in Poland. The questions focused on the respondents’ beliefs about pronunciation, teachers’ competences regarding pronunciation and pronunciation teaching, and the pronunciation teaching techniques they use. The results depict the most and least frequently used pronunciation teaching techniques at each of the three educational stages, and the beliefs of EFL teachers in Poland regarding …
ROLES AND REGISTERS IN DIGITAL FORUM INTERACTION: DEVELOPING A COMMUNICATIVE IDENTITY-BASED APPROACH TO REGISTER VARIATION
2017
espanolEl presente articulo estudia como los roles y registros comunicativos se expresan de forma interdependiente, influenciandose mutuamente en los actuales foros digitales. En la primera parte, y a partir de la combinacion de estudios previos sobre variacion de registros comunicativos, la teoria de la identidad social y la linguistica cognitiva, se proponen tres nuevos conceptos para el analisis discursivo: ‘Rol Modulador de Registro’ (RMR), ‘brujula del registro’ y ‘registro-pivote’. La forma en la que funcionan en el discurso digital se ilustra en la segunda parte, con el analisis de un corpus de foros de discusion. Los resultados demuestran que cada perfil de foro despliega una gama d…

Feedback practices in language classes in Finnish general upper secondary schools
2020
As feedback and formative assessment have a substantial effect on learning, the aim with this paper is to report on a study of the perceptions of Finnish general upper secondary school students of feedback in Swedish and English classes, and to compare how the perceptions differ at language proficiency (CEFR) levels. The data were collected by using a survey and were analysed quantitatively. The results show that several differences occur in Swedish: students with higher proficiency levels find feedback more useful, feel that they receive feedback from teachers, and are more willing to correct their own mistakes. There were no differences in perceptions according to language proficiency lev…
