In many plants belonging to angiosperms and gymnosperms the accumulation in leaves of long chain polyprenols and polyprenyl esters during growth in natural habitats depends on the light intensity. The amount of polyprenols in leaves is also positively correlated with the thickness of the leaf blade (SLA, specific leaf area). The polyprenol content of leaves shows seasonal changes with a maximum in autumn and a minimum in early summer with the difference between poorly and well illuminated plants persisting throughout the vegetation season.

Most modern ELT course books and language courses are designed to address one of four language skills at the time to ensure that enough time and attention is devoted to each one of them. Despite the fact that listening is included as one of these skills, it usually receives the least attention from teachers, who do not utilize the full potential of the exercises. The problem arises from miscategorising listening as a “passive” skill, which can be learnt effortlessly by simple exposure to the target language. In reality, listening can be taught but it is a rather demanding process, requiring more preparation from teachers as well as their willingness to demonstrate and share their extensive knowledge about sounds, decoding strategies and different listening techniques, which in turn aids students in identifying targets for practice. The aforementioned issue, i.e. treating listening as a passive skill and not using all possible teaching strategies associated with listening exercises, applies to all groups of students; however, older adult learners seem to be the most affected by it. The reason why older adults consider listening as one of the most challenging tasks stems from their reduced cognitive abilities and common hearing problems, which results in decreased speech comprehension ability and thus makes learning new languages even more challenging to them. The primary objective of the following article is thus to analyse student feedback in relation to listening exercises and to suggest possible improvements to teaching listening skills. Acquired results and conclusions shall serve as a basis for a possible expansion of the survey by adding teachers’ perspective and observations in the future.

The chapter sheds light on new conceptualizations of foreign language aptitude by emphasizing the role of working memory (WM). It is organised into 3 sections. The first section presents a brief historical overview of the research on language aptitude based on John Carroll’s work. The second part elaborates on working memory construct discussing Baddeley’s multi-component model of WM and its functions. The paper proposes incorporating working memory as a crucial component of language aptitude construct. In the light of the issue mentioned above, the third section of the article focuses on the newest and original empirical evidence which supports the role of WM in different aspects of L2 learning, i.e. reading, listening, speaking, writing and bilingual interpretation as well as vocabulary and grammar learning. Its concluding part reflects upon the relevance of language aptitude paving the way for future research.

Complex Dynamic Systems Theory (CDST), or complexity, is increasingly being used as a theoretical framework in Applied Linguistics. In this article, we present the reflections of researchers in Teaching English to Speakers of Other Languages (TESOL) about how they have made use of complexity in their work. The aim of this article is to take stock of how it is being used in the field, the challenges and benefits it provides, as well as inspiration for future work from this theoretical perspective. In the first part of the article, we present a concise overview of CDST, focusing specifically on three salient features: its holistic lens, its non-linear perspective on causality, and its focus on emergence and self-organisation. We also take stock of how complexity perspectives have been used to inform research in a variety of applied linguistics topics. We then move on to present narratives provided by nine academics who have employed CDST in their work, which we synthesise with a view to showing how the theory has gradually developed in TESOL. Early encounters of the field with CDST were usually serendipitous, but the theory has so far proved to be useful, both on account of its descriptive power and because of its phenomenological validity. A common theme in the narratives of these experiences of complexity researchers is that complexity is associated with a steep learning curve, compounded by terminological opacity, and conceptual challenges. However, their responses also indicate optimism regarding the potential of the theory to inform research in TESOL and applied linguistics more generally.

The SERSCIS approach aims to support the use of interconnected systems of services in Critical Infrastructure (CI) applications. The problem of system interconnectedness is aptly demonstrated by ‘Airport Collaborative Decision Making' (A-CDM). Failure or underperformance of any of the interlinked ICT systems may compromise the ability of airports to plan their use of resources to sustain high levels of air traffic, or to provide accurate aircraft movement forecasts to the wider European air traffic management systems. The proposed solution is to introduce further SERSCIS ICT components to manage dependability and interdependency. These use semantic models of the critical infrastructure, including its ICT services, to identify faults and potential risks and to increase human awareness of them. Semantics allow information and services to be described in a way that makes them understandable to computers. Thus when a failure (or a threat of it) is detected, SERSCIS components can take action to manage the consequences, including changing the interdependency relationships between services. In some cases, the components will be able to take action autonomously, e.g., to manage ‘local' issues such as the allocation of CPU time to maintain service performance, or the selection of services where there are redundant sources available. In other cases the components will alert human operators so they can take action instead. The goal of this paper is to describe a Service Oriented Architecture (SOA) that can be used to address the management of ICT components and interdependencies in critical infrastructure systems.

Listening is often listed as the most challenging language skill that the students need to learn in the language classrooms. Therefore the awareness of listening strategies and techniques, such as bottom-up and top-down processes, specific styles of listening, or various compensatory strategies, prove to facilitate the process of learning of older individuals. Indeed, older adult learners find decoding the aural input, more challenging than the younger students. Therefore, both students’ and teachers’ subjective theories and preferences regarding listening comprehension as well as the learners’ cognitive abilities should be taken into account while designing a teaching model for this age group. The aim of this paper is, thus, to draw the conclusions regarding processes, styles and strategies involved in teaching listening to older second language learners and to juxtapose them with the already existing state of research regarding age-related hearing impairments, which will serve as the basis for future research.

This study investigates the production of vowels in unstressed syllables by advanced German learners of English in comparison with native speakers of Standard Southern British English. Two acoustic properties were measured: duration and formant structure. The results indicate that duration of unstressed vowels is similar in the two groups, though there is some variation depending on the phonetic context. In terms of formant structure, learners produce slightly higher F1 and considerably lower F2, the difference in F2 being statistically significant for each learner. Formant values varied as a function of context and orthographic representation of the vowel.

The calculation of minimum regulatory capital for operational risk is a challenging task for statisticians working in finance. The aim of this paper is to compare two alternative approaches that are widely exploited in the banking reality. Thorough attention is paid to the Loss Distribution Approach (LDA) and the Single Loss Approximation (SLA). Their applications in the operational risk industry are examined and their outputs based on simulated samples are compared. Particular attention is paid to the convergence of both outputs considering the characteristics of underlying data.

The “love factor” has increasingly figured in SLA research. Thus, Piller (2002) studied the language “glue” between cross-lingual couples; Marinova-Todd (2003) found a link between L2 proficiency and co-habitation with native speakers; Muñoz & Singleton (2007) reported a romantic connection between successful late L2 learners and native speakers; Gonçalves (2013) explored hybridity in bicultural relationships; and Kinsella & Singleton (2014) found that the participants in their study of late L2 learners whose L2 test results were all within native-speaker range had native-speaker life-partners. This issue is now being taken very seriously, as Dewaele & Salomidou’s (2016) recent article on “loving … in a foreign language” demonstrates. In the present article we report on the results of some recent qualitative research, based on interview data collected from five individuals who are involved in intercultural and cross-lingual relationships. The research shows the L2 learning process to be clearly influenced by the affective context in which it occurs. The data also suggest that identity construction may be moved in a particular direction by the language principally adopted by the couple, and that, for the partner for whom this language is an L2, the results can be dramatic in terms of both linguistic and cultural affiliation.

The purpose of the study has been an analysis of Polish students’ cued translation of Polish (L1) and English or French (L2) sentences into Portuguese (third or additional language in De Angelis’s (2007) terminology). In particular, the study investigates cross-linguistic interaction (Herdina and Jessner’s (2002) term) in multilingual processing involved in L3 production. In fact, translation constitutes a special case of production because, on the one hand, the content is already contained in the L1 or L2 source sentences, but at the same time, this is not necessarily a facilitation, as the cues may require the use of words or structures the participants might not use in free production.The article is based on two studies carried out with thirty and forty-two students of Portuguese philology respectively. As the results show, cross-linguistic interaction in various directions was observed, not only from L2 (English or French), L3 (in those participants for whom Portuguese was an L4 and their L3 was Spanish or Italian), L4, etc. or, intralingually, from Portuguese, but also from L1, despite the distance between Polish and Portuguese and the special status of the native language. However, the amount of interference and/or negative transfer often depended on the sentence rather than on the language combination. The diversity of the observed interactions also supports Herdina and Jessner’s (2002) claim of the dynamic and unpredictable nature of cross-linguistic interaction.

Positive psychology was founded on three main pillars: positive emotions, positive character traits associated with good living and positive institutions that create conditions for students to flourish (Seligman and Csikszentmihalyi, 2000). Nevertheless, the research in psychology so far has been concentrating on positive emotions and character strengths. Enabling institutions have been the least well studied of the three pillars. A salient additional perspective, as MacIntyre and Mercer (2014) propound, would be to concentrate on the context in which students can experience enjoyment and flourish in foreign language learning. I try to fill the niche by analyzing a language school in the further education context in Poland which seems to be a positive institution. I base my study around the two criteria: enabling success and promoting positive language learning environments or student well-being. The language school is analysed from three different angles: physical, pedagogical and psychological by means of an ethnographical research method and participant observation. The study is carried out in order to answer the research question: Can the school be labelled as a positive institution? The results demonstrate that the institution enables success as well as provides a positive learning environment and thus could be regarded as positive. The study is hoped to have contributed to positive psychology research by demonstrating what it means to be a positive institution in practice.

In the field of numerical research there are various approaches and methods for structures of porous materials modeling. The solution is the use of fractal models to develop the porous structure. In the case of modeling the geometry of natural (random) materials, there is a problem of compatibility of the FE model geometry and real one. This is a source of differences between the results of calculations and experimental ones. Application of 3D printing technology will allow to receive a real structure in a controlled manner, which exactly reflects the designed structure and is consistent with the geometry of the numerical model. An experimental research on the standard samples made of photopolymer resin using 3D printing technique was presented in the paper. The aim of the research was to determine the base material properties and, consequently, to select the constitutive model, which is necessary to carry out numerical analyses.

There are various theories, strategies and techniques regarding teaching different language skills. At the same time, as practice shows listening remains the most challenging skill for the educators to teach effectively and for the learners to master. Moreover, both the learners and their teachers have their own, not infrequently rather disparate, subjective theories, as well as learning and teaching preferences. Older adult learners are a peculiar case as they are a very diverse group, aware of their needs and cognitive abilities. At the same time, their teachers are unfortunately often unaware of these needs and do not adapt the materials to suit their students. The aim of this paper is, thus, to present the opinions of the teachers of older adult students and to provide basis for future research.
