Abstract At Ångström Laboratory, one of the largest campuses at Uppsala University, the Library and the Student Services Office merged in November 2012. This merger is a pilot project to improve service for students and faculty. Ångström Laboratory has around 900 staff and almost 10,000 students, of whom most also spend time at other campuses. In this paper we describe the background and the implementation of the pilot project. One of the main reasons for moving together was the wish to gather together all kinds of student services, including the distribution of written examinations in one place. The central location and open environment of the Library made it a good choice. The heart of the Library and Student Services is an open office consisting of two service desks located in the library area. There are silent study areas; computers for searching and printing, an area for relaxing with newspapers and journals, meeting rooms and offices for the staff. The result is a lively place with a cosy atmosphere. As the Library and the Student Services still belong to different parts of the University we are now starting to find out how best to collaborate. To understand more we log all the questions we get and the services we deliver. We also have meetings together and use the same lunch room to get to know each other and our different functions. We will define which matters can be solved in common, and how we can back each other up when necessary.

The aim of this thematic study is to examine how the water motif is used in Marguerite Duras’s literary work. The study shows that water has multiple functions in these texts: it is linked to major themes and creates an enigmatic atmosphere by its association with the unknown, the inexplicable and the unconscious. The strong presence of water in Duras’s texts is striking. References to the water element can be found in several titles throughout her career, from early works such as Un barrage contre le Pacifique (1950) to La mer écrite (1996), published just after her death. Almost all of her fiction take place near water – and the rain or the sound of waves serve as leitmotifs in specific novels. The water motif can play a metonymic as well as a metaphoric role in the texts and it sometimes takes on human or animalistic characteristics (Chapter 4). Several emblematic Durassian characters (e.g. the beggar-woman, Anne-Marie Stretter and Lol V. Stein) have a close relationship to water (Chapter 5). The water motif is linked to many major Durassian themes, and illustrates themes with positive connotations, for example, creation, fecundity, maternity, liberty and desire, as well as themes with negative connotations such as destruction and death (Chapter 6). A close reading of three novels, La vie tranquille (1944), L’après-midi de Monsieur Andesmas (1962) and La maladie de la mort (1982), shows that the realism of the first novel is replaced by intriguing evocations of the sea and the pond in the second text, motifs which resist straightforward interpretation. The enigmatic feeling persists in the last novel, in which the sea illustrates the overall sombre mood of the story (Chapter 7). Finally, the role of the water element in psychoanalytic theory is discussed (Chapter 8), and a parallel is drawn between the Jungian concept of the mother archetype and the water motif in Duras’s texts. The suggestion is made in this last chapter that water is used to illustrate an oriental influence (Taoist or Buddhist) of some of the female characters in Duras’s work.

The shelter as a recurrent solution to homelessness During most of the 20th century shelters for the homeless has been criticized as being of too low standard and an unworthy way of living in a welfare society. During the 1960s and 1970s most shelters in Sweden were shut down and replaced with other forms of housing for the homeless. Since the late 1980s and early 1990s the issue of homelessness has returned to the political agenda as an existing social problem in Sweden. In this period we have also experienced a return of the shelters. These newly opened shelters are in many ways based on the same ideas like the old shelters described in stories of poverty and deprivation from the 19th century. In our article we raise the question how a system that has been rejected and condemned from both ethical and ideological standpoints as an unworthy way of living can be “remodernized” and considered again as a (temporary) solution to homelessness. We examine how shelters are justified in the 21st century and what functions they fill. We also discuss the fact that the shelters are almost exclusively run by (religious) voluntary organizations.

Research objectives Poker and responsible gambling both entail the use of the executive functions (EF), which are higher-level cognitive abilities. The main objective of this work was to assess if online poker players of different ability show different performances in their EF and if so, which functions are the most discriminating ones. The secondary objective was to assess if the EF performance can predict the quality of gambling, according to the Gambling Related Cognition Scale (GRCS), the South Oaks Gambling Screen (SOGS) and the Problem Gambling Severity Index (PGSI). Sample and methods The study design consisted of two stages: 46 Italian active players (41m, 5f; age 32±7,1ys; education 14,8±3ys) fulfilled the PGSI in a secure IT web system and uploaded their own hand history files, which were anonymized and then evaluated by two poker experts. 36 of these players (31m, 5f; age 33±7,3ys; education 15±3ys) accepted to take part in the second stage: the administration of an extensive neuropsychological test battery by a blinded trained professional. To answer the main research question we collected all final and intermediate scores of the EF tests on each player together with the scoring on the playing ability. To answer the secondary research question, we referred to GRCS, PGSI and SOGS scores.  We determined which variables that are good predictors of the playing ability score using statistical techniques able to deal with many regressors and few observations (LASSO, best subset algorithms and CART). In this context information criteria and cross-validation errors play a key role for the selection of the relevant regressors, while significance testing and goodness-of-fit measures can lead to wrong conclusions.   Preliminary findings We found significant predictors of the poker ability score in various tests. In particular, there are good predictors 1) in some Wisconsin Card Sorting Test items that measure flexibility in choosing strategy of problem-solving, strategic planning, modulating impulsive responding, goal setting and self-monitoring, 2) in those Cognitive Estimates Test variables related to deductive reasoning, problem solving, development of an appropriate strategy and self-monitoring, 3) in the Emotional Quotient Inventory Short (EQ-i:S) Stress Management score, composed by the Stress Tolerance and Impulse Control scores, and in the Interpersonal score (Empathy, Social Responsibility, Interpersonal Relationship). As for the quality of gambling, some EQ-i:S scales scores provide the best predictors: General Mood for the PGSI; Intrapersonal (Self-Regard; Emotional Self-Awareness, Assertiveness, Independence, Self-Actualization) and Adaptability  (Reality Testing, Flexibility, Problem Solving) for the SOGS, Adaptability for the GRCS. Implications for the field Through PokerMapper we gathered knowledge and evaluated the feasibility of the construction of short tasks/card games in online poker environments for profiling users’ executive functions. These card games will be part of an IT system able to dynamically profile EF and provide players with a feedback on their expected performance and ability to gamble responsibly in that particular moment. The implementation of such system in existing gambling platforms could lead to an effective proactive tool for supporting responsible gambling.

In this article, we discuss ellipsis as an interactive strategy by analysing the author’s textchat corpus and the VOICE corpus of English as a Lingua Franca. It is found that there were fewer repetitions in the textchat data, and this is explained as a consequence of the textchat mode. Textchat contributions are preserved as long as the chat is active or has been saved, and therefore users can scroll through and review the discussion, compared to the more fleeting nature of oral conversation. As a result, repetition is less necessary. The frequency of other functions identified could be attributed to the topic of discourse. Discussions involve much ellipsis used to develop discourse, although some were self-presentations with repetition used to confirm details. Back-channel support and comments were often low because speakers instead used forms like yeah as supportive utterances.

In this work, I will discuss the integral role that myth has in society and then, after presenting several examples of this thesis, I will examine how the integral nature of myth lends itself to certain societal abuses. These abuses often result in unjust social constructs that eventually become attributed to the myth. I would like to proceed in defense of myth; that is, that these constructs are not to be attributed to the myths themselves, rather, society has taken myth and applied it to suit its purposes, ignoring the context in which the myths originated. Hopefully this will raise society's current attitudes toward myth to a level of respect, and will also help to clear myth of its reputation as the origin of injustice and domination.
