The role of picture book storytelling used with Realia in the EFL YLs´ vocabulary acquisition

113 páginas incluye diagramasEn este artículo se reporta un estudio desarrollado para ayudar a un grupo de 12 niños estudiantes de Inglés como Lengua Extranjera a incrementar su rango de vocabulario, a través de la lectura de Pictolibros acompañados con “Realia”, una estrategia de enseñanza en donde objetos reales son traídos al salón de clases como ejemplos o como ayudas para hablar o escribir. Esta investigación tuvo una duración de 8 semanas y fue realizada en la escuela privada “Fundación Educativa Rochester” ubicada en Chía (Cundinamarca), a las afueras de Bogotá, la ciudad capital de Colombia. Los siguientes instrumentos fueron implementados con el fin de medir el impacto de esta investigación: un único examen aplicado al inicio y al final del tratamiento, diarios de campo y cuatro listas de chequeo utilizadas durante el tratamiento. Se emplearon tabulación cruzada y codificación para el análisis de datos. Los resultados revelaron que el uso de Pictolibros acompañados con “Realia”, puede tener un impacto positivo en niños estudiantes de inglés como Lengua Extranjera con habilidades lingüísticas limitadas. Adicionalmente, se encontró que permitir a los niños tomar decisiones sobre algunos elementos de las actividades propuestas para la clase de inglés como lengua extranjera, promueve aprendizaje autónomo, ya que fue evidente como los participantes se apropiaron de su propio proceso de aprendizaje.

Lineability and modes of convergence

In this paper we look for the existence of large linear and algebraic structures of sequences of measurable functions with different modes of convergence. Concretely, the algebraic size of the family of sequences that are convergent in measure but not a.e. pointwise, uniformly but not pointwise convergent, and uniformly convergent but not in L1-norm, are analyzed. These findings extend and complement a number of earlier results by several authors.Junta de AndalucíaMinisterio de Ciencia, Innovación y Universidades (MICINN). Españ

Comparable GHG emissions from animals in wildlife and livestock-dominated savannas

Pastoralism in Old World savannas is known to emit a significant share of global livestock-sourced greenhouse gases (GHG). Here, we compare calculated emissions from animals in a wildlife-dominated savanna (14.3 Mg km(-2)), to those in an adjacent land with similar ecological characteristics but under pastoralism (12.8 Mg km(-2)). The similar estimates for both, wildlife and pastoralism (76.2 vs 76.5 Mg CO2-eq km(-2)), point out an intrinsic association of emissions with herbivore ecological niches. Considering natural baseline or natural background emissions in grazing systems has important implications in the analysis of global food systems.Peer reviewe

The role of the European small ruminant dairy sector in stabilising global temperatures : lessons from GWP* warming-equivalent emission metrics

Recent calls advocate that a huge reduction in the consumption of animal products (including dairy) is essential to mitigate climate change and stabilise global warming below the 1.5 and 2°C targets. The Paris Agreement states that to stabilise temperatures we must reach a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases (GHG) in the second half of this century. Consequently, many countries have adopted overall GHG reduction targets (e.g. EU, at least 40% by 2030 compared to 1990). However, using conventional metric-equivalent emissions (CO2-e GWP100) as the basis to account for emissions does not result in capturing the effect on atmospheric warming of changing emission rates from short-lived GHG (e.g. methane: CH4), which are the main source of GHG emissions by small ruminants. This shortcoming could be solved by using warming-equivalent emissions (CO2-we, GWP*), which can accurately link annual GHG emission rates to its warming effect in the atmosphere. In our study, using this GWP* methodology and different modelling approaches, we first examined the historical (1990–2018) contribution of European dairy small ruminant systems to additional atmosphere warming levels and then studied different emission target scenarios for 2100. These scenarios allow us to envision the necessary reduction of GHG emissions from Europe's dairy small ruminants to achieve a stable impact on global temperatures, i.e. to be climatically neutral. Our analysis showed that, using this type of approach, the whole European sheep and goat dairy sector seems not to have contributed to additional warming in the period 1990–2018. Considering each subsector separately, increases in dairy goat production has led to some level of additional warming into the atmosphere, but these have been compensated by larger emission reductions in the dairy sheep sector. The estimations of warming for future scenarios suggest that to achieve climate neutrality, understood as not adding additional warming to the atmosphere, modest GHG reductions of sheep and goat GHG would be required (e.g. via feed additives). This reduction would be even lower if potential soil organic carbon (SOC) from associated pastures is considered.Peer reviewe

El concursamiento en las entidades financieras

Best Practices in Road Transport: An Exploratory Study

Purpose: Road transport aspects are becoming increasingly important due to their high impact on economic, environmental and social sustainability. Considering the triple bottom line approach, best practices play a fundamental role within organisations. The purpose of this paper is to analyse several sustainable initiatives in road transport adopted by companies. Design/methodology/approach: The findings were developed and evaluated based on empirical data captured through a survey of 98 professionals involved in logistics and transport activities. Additionally, key literature on transport initiatives was reviewed to supplement the framework for the implementation of best practices in road transport. Findings: The exploratory study shows the importance of each best practice and determines the level of implementation of each initiative, comparing the results among different dealers (retailers, wholesalers, carriers and manufacturers), type of transport fleet and companies’ revenues. Research limitations/implications: The sample of 98 companies was based on simple search filters and the group is not wholly representative of all sectors. Respondents were mainly managers from Spain involved in logistics and transport activities. Surveyed companies included manufacturing, retailers, wholesalers and third-party logistics providers. Practical implications: The most common best practices in road transport are identified, including initiatives related to: efficiency, reusability, safety, optimization, emissions, waste and recycling. Initiatives that influence road transport are ranked by their degree of implementation in the companies analysed. Social implications: Implementation of some of these best practices may help lessen negative impacts of road transport on society and the environment. Originality/value: The study results indicate which practices are most frequently used and their level of implementation depending on companies’ roles in the supply chain, revenues and types of transport fleet. By implementing the proposed best practices, companies will adopt sustainable behaviors to improve their transport performance.Peer Reviewe

Economic and Environmental Packaging Sustainability: A Case Study

Purpose: The aim of this paper is to analyze the suitability of the packaging strategy of an important Spanish agro-food company, regarding to economic and environmental sustainability. Design/methodology/approach: Three different types of packaging are analyzed to obtain a diagnostic of the initial situation. In this process, cost and carbon footprint are calculated in order to measure the economic and environmental impacts, respectively. Then, a new packaging allocation logic is proposed with the aim of improving both aspects. Findings: The results show that the carbon footprint is strongly and positively affected by the cost reduction, showing the viability of a win-win relationship between both aspects. Research limitations/implications: The strength of this win-win relationship may be conditioned by the input values considered in this case study. Conversion factors used to calculate carbon footprint vary a lot among researchers, showing the need of standardization in this topic. P r a c tic al im plic a tio n s: Since the existence of a positive relationship between economic and environmental sustainability has been demonstrated, organizations should find this kind of situations in themselves to satisfy their own stakeholders. Originality/value: This article shows the potential of unite waste elimination with eco-friendly activities with the aim of increasing the competitiveness of companies. This paper also contributes to the knowledge of economic and environmental sustainability and reinforces theoretical aspects, paving the way for further research on these topics.Peer Reviewe
