Designing informal learning experiences for early career academics using a knowledge ecosystem model
Resumo:
This article presents a ‘knowledge ecosystem’ model of how early career academics experience using information to learn while building their social networks for developmental purposes. Developed using grounded theory methodology, the model offers a way of conceptualising how to empower early career academics through 1) agency (individual and relational) and 2) facilitation of personalised informal learning (design of physical and virtual systems and environments) in spaces where developmental relationships are formed including programs, courses, events, community, home and social media. It is suggested that the knowledge ecosystem model is suitable for use in designing informal learning experiences for early career academics.

From a relational perspective of information literacy, health information literacy is interpreted as the different ways in which people experience using information to learn about health. Phenomenography was used as a research approach to explore variation in people's experience of using information to learn about health from data collected through semi-structured interviews. The findings identify seven categories that describe the qualitatively different ways in which people experience health information literacy: building a new knowledge base;weighing up information; discerning valid information; paying attention to bodily information; staying informed about health; Participating in learning communities, and envisaging health. These findings can be used to enhance awareness about the different ways of experiencing health information literacy, and to contribute to a nascent trajectory of research that has explored information literacy within the context of everyday life.

A study examined the politics of dis/ability and curriculum. Data were obtained from a review of the new disability studies literature, focusing on the areas of history, sociology, anthropology, and critical legal theory. The results indicate that this new literature challenges popular psychoeducational models that assume disability as an objective medical, individual, and pathological deficiency, effectively restricting the systematic study of dis/ability as relational, external, shifting, and socially constituted. The findings suggest ways in which perceptions of “school problems” have to be adjusted to understand how the constant refiguration of normativities in everyday activities creates perceptions of disability-negative ontologies, generates experiences that incite efforts to modify those perceptions in multiple ways, and produces unintended effects from well-intended approaches that in the end remain irreducible to simplistic definitions for the one “ethical” or “politically correct” strategy.

This paper presents a novel algebraic formulation of the central problem of screw theory, namely the determination of the principal screws of a given system. Using the algebra of dual numbers, it shows that the principal screws can be determined via the solution of a generalised eigenproblem of two real, symmetric matrices. This approach allows the study of the principal screws of the general two-, three-systems associated with a manipulator of arbitrary geometry in terms of closed-form expressions of its architecture and configuration parameters. We also present novel methods for the determination of the principal screws for four-, five-systems which do not require the explicit computation of the reciprocal systems. Principal screws of the systems of different orders are identified from one uniform criterion, namely that the pitches of the principal screws are the extreme values of the pitch.The classical results of screw theory, namely the equations for the cylindroid and the pitch-hyperboloid associated with the two-and three-systems, respectively have been derived within the proposed framework. Algebraic conditions have been derived for some of the special screw systems. The formulation is also illustrated with several examples including two spatial manipulators of serial and parallel architecture, respectively.

Computation of the dependency basis is the fundamental step in solving the implication problem for MVDs in relational database theory. We examine this problem from an algebraic perspective. We introduce the notion of the inference basis of a set M of MVDs and show that it contains the maximum information about the logical consequences of M. We propose the notion of an MVD-lattice and develop an algebraic characterization of the inference basis using simple notions from lattice theory. We also establish several properties of MVD-lattices related to the implication problem. Founded on our characterization, we synthesize efficient algorithms for (a) computing the inference basis of a given set M of MVDs; (b) computing the dependency basis of a given attribute set w.r.t. M; and (c) solving the implication problem for MVDs. Finally, we show that our results naturally extend to incorporate FDs also in a way that enables the solution of the implication problem for both FDs and MVDs put together.

This paper describes the design and implementation of ADAMIS (‘A database for medical information systems’). ADAMIS is a relational database management system for a general hospital environment. Apart from the usual database (DB) facilities of data definition and data manipulation, ADAMIS supports a query language called the ‘simplified medical query language’ (SMQL) which is completely end-user oriented and highly non-procedural. Other features of ADAMIS include provision of facilities for statistics collection and report generation. ADAMIS also provides adequate security and integrity features and has been designed mainly for use on interactive terminals.

This book is a study on learning, teaching/counselling, and research on the two. My quest has been to find a pedagogically-motivated way of researching learning and teaching interaction, and in particular counselling, in an autonomous language-learning environment. I have tried to develop a method that would make room for lived experience, meaning-making and narrating, because in my view these all characterise learning encounters between language learners and counsellors, and learners and their peers. Lived experience as a source of meaning, telling and co-telling becomes especially significant when we try to listen to the diverse personal and academic voices of the past as expressed in autobiographical narratives. I have aimed at researching various ALMS dialogues (Autonomous Learning Modules, University of Helsinki Language Centre English course and programme), and autobiographical narratives within them, in a way that shows respect for the participants, and that is relevant, reflective and, most importantly, self-reflexive. My interest has been in autobiographical telling in (E)FL [(English as a) foreign language], both in students first-person written texts on their language- learning histories and in the sharing of stories between learners and a counsellor. I have turned to narrative inquiry in my quest and have written the thesis as an experiential narrative. In particular, I have studied learners and counsellors in one and the same story, as characters in one narrative, in an attempt to avoid the impression that I am telling yet another separate, anecdotal story, retrospectively. Through narrative, I have shed light on the subjective dimensions of language learning and experience, and have come closer to understanding the emotional aspects of learning encounters. I have questioned and rejected a distanced and objective approach to describing learning and teaching/counselling. I have argued for a holistic and experiential approach to (E)FL encounters in which there is a need to see emotion and cognition as intertwined, and thus to appreciate learners and counsellors emotionally-charged experiences as integral to their identities. I have also argued for a way of describing such encounters as they are situated in history, time, autobiography, and the learning context. I have turned my gaze on various constellations of lived experience: the data was collected on various occasions and in various settings during one course and consists of videotaped group sessions, individual counselling sessions between students and their group counsellor, biographic narrative interviews with myself, open-ended personally-inspired reflection texts written by the students about their language-learning histories, and student logs and diaries. I do not consider data collection an unproblematic occasion, or innocent practice, and I defend the integrity of the research process. Research writing cannot be separated from narrative field work and analysing and interpreting the data. The foci in my work have turned to be the following: 1) describing ALMS encounters and specifying their narrative aspects; 2) reconceptualising learner and teacher autonomy in ALMS and in (E)FL; 2) developing (E)FL methodologically through a teacher-researcher s identity work; 4) research writing as a dialogical narrative process, and the thesis as an experiential narrative. Identity and writing as inquiry, and the deeply narrative and autobiographical nature of the (E)FL teaching/counselling/researching have come to the fore in this research. Research writing as a relational activity and its implications for situated ways of knowing and knowledge turned out to be important foci. I have also focussed on the context-bound and local teacher knowledge and ways of knowing about being a teacher, and I have argued for personal ways of knowing about, and learning and studying foreign languages. I discuss research as auto/biography: as a practising counsellor I use my own life and (E)FL experience to understand and interpret the stories of the research participants even though I was not involved in their course work. The supposedly static binaries of learner/teacher, and also learner autonomy/teacher autonomy, are thus brought into the discussion. I have highlighted the infinite variability and ever-changing nature of learning and teaching English, but the book is also of relevance to foreign language education in general.

This paper focuses on the fundamental right to be heard, that is, the right to have one’s voice heard and listened to – to impose reception (Bourdieu, 1977). It focuses on the ways that non-mainstream English is heard and received in Australia, where despite public policy initiatives around equal opportunity, language continues to socially disadvantage people (Burridge & Mulder, 1998). English is the language of the mainstream and most people are monolingually English (Ozolins, 1993). English has no official status yet it remains dominant and its centrality is rarely challenged (Smolicz, 1995). This paper takes the position that the lack of language engagement in mainstream Australia leads to linguistic desensitisation. Writing in the US context where English is also the unofficial norm, Lippi-Green (1997) maintains that discrimination based on speech features or accent is commonly accepted and widely perceived as appropriate. In Australia, non-standard forms of English are often disparaged or devalued because they do not conform to the ‘standard’ (Burridge & Mulder, 1998). This paper argues that talk cannot be taken for granted: ‘spoken voices’ are critical tools for representing the self and negotiating and manifesting legitimacy within social groups (Miller, 2003). In multicultural, multilingual countries like Australia, the impact of the spoken voice, its message and how it is heard are critical tools for people seeking settlement, inclusion and access to facilities and services. Too often these rights are denied because of the way a person sounds. This paper reports a study conducted with a group that has been particularly vulnerable to ongoing ‘panics’ about language – international students. International education is the third largest revenue source for Australia (AEI, 2010) but has been beset by concerns from academics (Auditor-General, 2002) and the media about student language levels and falling work standards (e.g. Livingstone, 2004). Much of the focus has been high-stakes writing but with the ascendancy of project work in university assessment and the increasing emphasis on oracy, there is a call to recognise the salience of talk, especially among students using English as a second language (ESL) (Kettle & May, 2012). The study investigated the experiences of six international students in a Master of Education course at a large metropolitan university. It utilised data from student interviews, classroom observations, course materials, university policy documents and media reports to examine the ways that speaking and being heard impacted on the students’ learning and legitimacy in the course. The analysis drew on Fairclough’s (2003) model of the dialectical-relational Critical Discourse Analysis (CDA) to analyse the linguistic, discursive and social relations between the data texts and their conditions of production and interpretation, including the wider socio-political discourses on English, language difference, and second language use. The interests of the study were if and how discourses of marginalisation and discrimination manifested and if and how students recognised and responded to them pragmatically. Also how they juxtaposed with and/or contradicted the official rhetoric about diversity and inclusion. The underpinning rationale was that international students’ experiences can provide insights into the hidden politics and practices of being heard and afforded speaking rights as a second language speaker in Australia.

From Steely Nation-State Superman to Conciliator of Economical Global Empire – A Psychohistory of Finnish Police Culture 1930-1997 My study concerns the way police culture has changed within the societal changes in Finnish society between 1930 and 1997. The method of my study was psycho-historical and post-structural analysis. The research was conducted by examining the psycho-historical plateaus traceable within Finnish police culture. I made a social diagnosis of the autopoietic relationship between the power-holders of Finnish society and the police (at various levels of hierarchical organization). According to police researcher John P. Crank, police culture should be understood as the cognitive processes behind the actions of the police. Among these processes are the values, beliefs, rituals, customs and advice which standardize their work and the common sense of policemen. According to Crank, police culture is defined by a mindset which thinks, judges and acts according to its evaluations filtered by its own preliminary comprehension. Police culture consists of all the unsaid assumptions of being a policeman, the organizational structures of police, official policies, unofficial ways of behaviour, forms of arrest, procedures of practice and different kinds of training habits, attitudes towards suspects and citizens, and also possible corruption. Police culture channels its members’ feelings and emotions. Crank says that police culture can be seen in how policemen express their feelings. He advises police researchers to ask themselves how it feels to be a member of the police. Ethos has been described as a communal frame for thought that guides one’s actions. According to sociologist Martti Grönfors, the Finnish mentality of the Protestant ethic is accentuated among Finnish policemen. The concept of ethos expresses very well the self-made mentality as an ethical tension which prevails in police work between communal belonging and individual freedom of choice. However, it is significant that it is a matter of the quality of relationships, and that the relationship is always tied to the context of the cultural history of dealing with one’s anxiety. According to criminologist Clifford Shearing, the values of police culture act as subterranean processes of the maintenance of social power in society. Policemen have been called microcosmic mediators, or street corner politicians. Robert Reiner argues that at the level of self-comprehension, policemen disparage the dimension of politics in their work. Reiner points out that all relationships which hold a dimension of power are political. Police culture has also been called a canteen culture. This idea expresses the day-to-day basis of the mentality of taking care of business which policing produces as a necessity for dealing with everyday hardships. According to police researcher Timo Korander, this figurative expression embodies the nature of police culture as a crew culture which is partly hidden from police chiefs who are at a different level. This multitude of standpoints depicts the diversity of police cultures. According to Reiner, one should not see police culture as one monolithic whole; instead one should assess it as the interplay of individuals negotiating with their environment and societal power networks. The cases analyzed formed different plateaus of study. The first plateau was the so-called ‘Rovaniemi arson’ case in the summer of 1930. The second plateau consisted of the examinations of alleged police assaults towards the Communists during the Finnish Continuation War of 1941 to 1944 and the threats that societal change after the war posed to Finnish Society. The third plateau was thematic. Here I investigated how using force towards police clients has changed culturally from the 1930s to the 1980s. The fourth plateau concerned with the material produced by the Security Police detectives traced the interaction between Soviet KGB agents and Finnish politicians during the long 1970s. The fifth plateau of larger changes in Finnish police culture then occurred during the 1980s as an aftermath of the former decade. The last, sixth plateau of changing relationships between policing and the national logic of action can be seen in the murder of two policemen in the autumn of 1997. My study shows that police culture has transformed from a “stone cold” steely fixed identity towards a more relational identity that tries to solve problems by negotiating with clients instead of using excessive force. However, in this process of change there is a traceable paradox in Finnish policing and police culture. On the one hand, policemen have, at the practical level, constructed their policing identity by protecting their inner self in their organizational role at work against the projections of anger and fear in society. On the other hand, however, they have had to safeguard themselves at the emotional level against the predominance of this same organizational role. Because of this dilemma they must simultaneously construct both a distance from their own role as police officers and the role of the police itself. This makes the task of policing susceptible to the political pressures of society. In an era of globalization, and after the heyday of the welfare state, this can produce heightened challenges for Finnish police culture.

The power of projects has been demonstrated by the growth in their use across an increasing range of industries and workplaces in recent years. Not only has the number of people involved in project management increased, but the qualifications and backgrounds of those people have also broadened, with engineering no longer being the only path to project management (PM). Predicting the career trajectories in Project Management has become more important for both organisations employing project managers and project managers building career portfolios. Our research involved interviewing more than 75 project officers and project managers across a range of industries to explore their career journey. We used Wittgenstein’s family resemblance theory is to analyse the information from the transcripts to identify the extent to which the roles of participants fit with the commonly accepted definition of project management. Findings demonstrate diversity of project manager backgrounds and experiences and relational competencies across these backgrounds that form and shape PM careers.

This thesis concerns Swedish and Finland-Swedish brochures to families with children, presenting family allowances from the social insurance institutions in the two countries. The aim of the study is to analyse what meanings are conveyed with reference to the conceivable reader and the institution in the brochures. The material consists of information brochures in Swedish from Kela, the social insurance institution of Finland, and Försäkringskassan, the Swedish social insurance agency, issued during 2003–2006. The general theoretical framework is systemic-functional linguistics (SFL) as presented by Halliday & Matthiessen (2004) and Holmberg & Karlsson (2006). The study consists of a quantitative study of the lexical choices of the social insurance brochures. Furthermore, a qualitative process and participant analysis is annotated with the UAM Corpus tool and the results are quantified. Speech functions and modal auxiliaries are analysed qualitatively. The analysis shows that material and relational processes are most common. The relational and verbal processes are used more in the Sweden-Swedish brochures, while the material processes are more common in the Finland-Swedish brochures. The participants in the brochures are the institution, mentioned by its name, and the conceivable reader, directly addressed with “you” (du). In addition, the referent “child” is often mentioned. The participants assigned for the reader are Actor, Receiver, Carrier and Speaker. In the Finland-Swedish texts, the reader is often an Actor, while the reader in the Sweden-Swedish texts is a Carrier. Thus, the conceivable reader is an active participant who takes care of his or her own matters using the internet, communicates actively to the institution and has legal rights and obligations. The institution is visible in the texts but does not have an active role as the name of the institution is mostly used in circumstances. The institution is not often a participant, but when it is, it is Actor, Receiver, Listener and Carrier, expecting the clients to address it. Speech functions are performed in different ways. For instance, questions structure the reading process and commands are realised by modal auxiliaries, not by imperatives. The most common modal auxiliary is kan (can, may), and another common auxiliary is ska (shall, must). Statements are surrounded by subordinate clauses and adverbs that describe situations and criteria. The results of the study suggest that the brochures in the two countries are similar, in particular when produced in similar ways, that is, when the Finland-Swedish texts are not translated. Existing differences reflect the differences in the institutions, the social insurance systems and the cultural contexts.

The study describes the use and meaning of the Finnish demonstrative pronouns, focus being on the pronoun "tämä" (roughly 'this'). The Finnish demonstrative system is a three way one, the other two demonstratives are "tuo" ('that') and "se" ('it'). The data consisted of 12 half hours of video- and tape-recorded face-to-face and telephone conversations. The method for the study was ethnomethodological conversation analysis (CA); in addition to CA, the theoretical framework consisted of functional linguistics and linguistic anthropology. First, the study dealt with the syntactic distribution of the three demonstratives. The pronouns were analysed according to whether they are before or after the verb, and whether they compose an NP on their own or are determinants of a lexical NP. The study suggested that the form and the placement of the NP presents the referent as continuous/discontinuous or given/new. Givenness of a referent was defined as "identified adequately for the purposes of the on-going action". The so-called dislocated utterances were considered separately. It was found that left-dislocations are used for inserting referents in a particular relation to the on-going activity. Right-dislocations offer a solution for the sometimes competing motivations of newness and continuity: they are used for securing the identifiability of a referent that is implied to be continuous. Second, the study focussed on analysing the meaning of the pronouns according to three dimensions of reference: referential, indexical and relational. It was found that the demonstratives can organize interactional or spatial context. When organizing interactional context, the demonstrative pronouns express the role of identifying the referent in relation to the on-going activity. The pronoun "tämä" expresses that the referent is referentially open and the characterization of the referent is given in the on-going turn. Furthermore, it expresses asymmetry of the indexical ground: it expresses that the participants of a conversation do not share a mutual understanding of the activity at that particular time. In addition, the referent of the pronoun "tämä" is central for understanding the on-going action. Centrality could be understood as the relational feature of the pronoun. However, it is a consequence of the referential and indexical features of "tämä". The pronoun "tuo" also expresses referential openness, but it implies indexical symmetry. The pronoun "se" implies that the referent is known enough, and implies indexical symmetry. When used spatially, the pronouns may refer to a physical space or to a situation. They express or imply that the speaker is inside or outside the referent. The pronoun "tämä" implies inclusion, and the pronoun "tuo" expresses exclusion.

This paper addresses the ways in which humour is used by university academics to shape teaching personas. Based upon the work of Mauss and Foucault, and employing semi-structured, in-depth interviews with a range of university teachers, this research suggests that most tertiary teachers deliberately fashion various kinds of teaching persona, which they then perform in lectures and tutorials. The use of humour is widely seen as an important component within this form of self-shaping, as it fits within dominant frameworks of expectation regarding contemporary models of “edutainment”. This research demonstrates that a wide range of practices of the self—including physical, verbal, and relational elements—are employed by academics as part of shaping various humorous teaching personas. Some boundaries exist limiting the use of these pedagogic characters; for example, arguments about natural ability with humour prefigure who is most likely to deploy humour as a practice of professional self-formation. Also, professional concerns regarding seniority and job security are also factored into decision-making regarding those humorous personas likely to be considered appropriate within particular tertiary teaching contexts.
