Pattern Mining and Sense-Making Support for Enhancing the User Experience

Mukherji, Abhishek 07 December 2018 (has links)
While data mining techniques such as frequent itemset and sequence mining are well established as powerful pattern discovery tools in domains from science, medicine to business, a detriment is the lack of support for interactive exploration of high numbers of patterns generated with diverse parameter settings and the relationships among the mined patterns. To enhance the user experience, real-time query turnaround times and improved support for interactive mining are desired. There is also an increasing interest in applying data mining solutions for mobile data. Patterns mined over mobile data may enable context-aware applications ranging from automating frequently repeated tasks to providing personalized recommendations. Overall, this dissertation addresses three problems that limit the utility of data mining, namely, (a.) lack of interactive exploration tools for mined patterns, (b.) insufficient support for mining localized patterns, and (c.) high computational mining requirements prohibiting mining of patterns on smaller compute units such as a smartphone. This dissertation develops interactive frameworks for the guided exploration of mined patterns and their relationships. Contributions include the PARAS pre- processing and indexing framework; enabling analysts to gain key insights into rule relationships in a parameter space view due to the compact storage of rules that enables query-time reconstruction of complete rulesets. Contributions also include the visual rule exploration framework FIRE that presents an interactive dual view of the parameter space and the rule space, that together enable enhanced sense-making of rule relationships. This dissertation also supports the online mining of localized association rules computed on data subsets by selectively deploying alternative execution strategies that leverage multidimensional itemset-based data partitioning index. Finally, we designed OLAPH, an on-device context-aware service that learns phone usage patterns over mobile context data such as app usage, location, call and SMS logs to provide device intelligence. Concepts introduced for modeling mobile data as sequences include compressing context logs to intervaled context events, adding generalized time features, and identifying meaningful sequences via filter expressions.

The Encultured Mind: From Cognitive Science to Social Epistemology

Eck, David Alexander 12 March 2015 (has links)
There have been monumental advances in the study of the social dimensions of knowledge in the late twentieth and early twenty-first centuries. But it has been common within a wide variety of fields--including social philosophy, cognitive science, epistemology, and the philosophy of science--to approach the social dimensions of knowledge as simply another resource to be utilized or controlled. I call this view, in which other people's epistemic significance are only of instrumental value, manipulationism. I identify manipulationism, trace its manifestations in the aforementioned fields, and explain how to move beyond it. The principal strategy that I employ for moving beyond manipulationism consists of synthesizing enactivism and neo-Kuhnian social epistemology. Specifically, I expand the enactivist concept of participatory sense-making by linking it to recent conceptual innovations in social epistemology, such as the concept of immanent cogent argumentation.

How are strategy tools used in practice in a university context?

Hutchinson, Collette January 2009 (has links)
<p>Many business schools teach the importance of using strategy tools when engaging in strategizing activities. Despite this fact there is an ongoing debate concerning what is taught in business schools and what is actually used in practice. In spite of this debate there has been little research done regarding how these strategy tools are used in practice. This study seeks to address this through the adoption of a strategy as practice perspective which helped to identify what is actually practiced by managers while engaging in strategizing activities. Managers use strategy to respond to complex forces (social, political, economic) in their business environments. However to develop and implement strategy encompasses a full range of strategizing activities such as strategic thinking, strategic analysis, strategic decision making and implementation. Many business schools teach strategy tools are techniques which managers use to structure and influence strategizing activities. Previous research on strategy tools played emphasis on the benefits that can be derived if tools are used in different context. Others have highlighted the frequency of tool usage. Nevertheless, there is a need to make a review what is taught and how strategy tools are used in practice.</p><p>A qualitative study was conducted in two universities through the use of semi structured interviews to gather data. The use of an inductive and interpretivism perspective through a case study helped the researcher identify the context in which events were taking place. The choice of a small yet deliberate sample size was done to focus in on the various levels of management within these universities and to review how strategy tools were used at these levels. After each interview the interviewees were given a list of 15 strategy tools (all of which were taught in the researcher’s masters programme) to identify whether they used any of the strategy tools on the list and if they did how did they use them. It was noted from the empirical data acquired that quite often strategy tools were not always being used for the purpose for which they were taught nevertheless managers were altering components of various tools to meet their individual business needs. Strategy tools were often used to assist in strategic thinking and strategic decision making. Managers’ perception of strategy tools affected the extent to which tools were used and the frequency of usage. While strategy tools were often used for growth and development, communication and persuasion and best practices it was its use in sense-making and evaluation which indicated that there is a need for a greater understanding into how managers make sense of strategy tools. The study answers how strategy tools are used in practice in a university context by giving illustrations and quotations from the various interviewees regarding strategy tools.</p>

Nurses Work Environment & Technological Innovation Adoption: Acquiring Knowledge after Making Sense of it all

Janice M. Pickney 8 May 2008 (has links)
Clinical information systems are being introduced into nurses’ work at an alarming rate. These systems are implemented with limited input from nurses who provide direct patient care, and without considering human factors in the systems design and implementation process. The need for nurses to be involved at every level of decision-making as it relates to technological innovation into their work is imperative to mitigate system failure and truly support their work. Therefore, the purpose of this paper is two-fold: 1) to discuss evidence that suggests that the nurse is not really viewed as an end user in most clinical information systems implementations and 2) to describe the implications of this misperception to the nurse, organization, and nursing profession.

Growing old and still practising competitive sports : An exploration of acting-space and sense-making processes among old women and men

Eman, Josefin January 2012 (has links)
The thesis explores how the way athletically active old men and women make sense of their acting-space affects their participation in competitive sports and conversely how their participation in competitive sports affect their sense-making process and acting-space. It puts emphasis on the sociological point of intersection of three different research fields; sports science, critical gerontology and gender studies. Concretely, it is inspired by grounded theory research design and based on interviews with twenty-two athletically active men and women over the age of 65. The thesis consists of four articles, and together these show that men and women experience certain constraints of acting-space in the context of competitive sports, which primarily seem to be related to norms of age and gender. At the same time, the thesis shows that by practising sports old adults, especially old women, are able to transgress these constraints and possibly challenge dominant constructions of age and gender.

Spirande polisidentiteter : En studie av polisstudenters och nya polisers professionella identitet

Lauritz, Lars Erik January 2009 (has links)
Who am I? Who are we? And how are the two entities connected? These are key issues of this study. Socialization and other sense making processes create new social identities. One possible identity is a professional one. Professional identities are discussed as a construction where expectations and experiences of construed images, cultural and professional understandings are key elements. Social identities are fundamentally described as social and individual reflections. The purpose of the study is to extend the comprehension of how professional identities are constructed and to study new professionals navigation through the complex network of images and contrasting pictures that meet them in that process. The professional identity of Swedish police officers is focused. The profession is - by many of the ten informants in this recurrent, in-depth interview study - described as a dream from childhood. The first of four interview-series has been conducted in beginning of police education, the last after nine months work experience. There are two motives that all informants mention for choosing the profession. The first is a wish to care for others and for the society, the second is excitement. Other mentioned motives are the police profession regarded as teamwork with a high community spirit. It is expected to give good opportunities to develop as individuals and is thought to be a practical occupation, described with key words such as handy and flexible. The construed image, how informants believe that others view the profession, is described either as polices as the selected model or as prejudiced and hostile. The mass media is regarded the main intermediary of the second image. By the informants, a good police is regarded as being without prejudices and is presented as male. Male strength is one desirable quality, though the strength preferably can be combined with female softness. The care-giving motive is accentuated as the most important one in the first interviews, but replaced by excitement as the most important one in practice. Some general discourses are discussed. The first three - the social, the recruitment, and the distrust discourse - are discussed as sources of understanding to the frequently discussed notion of the police profession as constituting strong team spirit. Police identity is also presented as unprejudiced, male and young in the sense of engagement and activity degree. All discourses are often challenged in work- experience, from cultural as well as from image perspectives. On a highly generalized level the police identity can be positioned as one with a high degree of community. When the stories are scrutinized clearly disparate patterns between individuals however appear. The differences are expressed either in accentuation or definition of the common labels. Earlier research on the fields of identity reveals some shortages. The individual's role in constructing social identities and the pure locus of identity is overlooked. To reduce that shortage, this study introduces a professional identity model where the individual´s position is connected to the common identity by expectations and experiences of three key identity elements -Culture, Image and the Profession itself.

External guest speakers, Curse or Blessing? : A study on external guest speakers and the personal fables they carry out, to see if, and mainly how, they can establish collective sense-making and centring within an organizational context.

Volkers, Gerardus, Oostveen, Bartholomeus January 2012 (has links)
Purpose The purpose of the paper is to explain how executives can make effective use of fables provided by external guest speakers to create a situation of collective sense-making and centring, based on the story used in a policy making context of a private, Dutch for-profit organization ( fictitiously called Con-Zelo recruitment agency in this article ).   Design/methodology/approach The approach involved collecting and analyzing the ‘Swimming for gold’ fable as part of seven months phenomenological and symbolic study, to confirm organizational sense, identify categorized themes and analyze the process of creation. In which co-author Volkers, as a former member, had access to the organization and familiarity with the organization its history.   Findings The findings emphasize that both fables and myths can in fact establish organizational sense and centring based on categorized themes. Most important is that fables shared by an external guest speaker should not be considered as a singular event, but as start of a process; a true vehicle for collective sense-making and centring. Organizations can then do so through changes and alignment in all five types of cultural artifacts.   Originality/value This paper provides additional value by bridging the gap between theory and practice. Besides illustrating that fables do in fact contain the power to promote a particular point of view, specific meaning and or values and therewith establish organizational sense and centring. This study includes the documentation and cultural analysis of the fable, and illustrates the fable as a vehicle or process for collective sense-making and centring. Furthermore, the suggested fable-stretching model is a so called ‘soup-to-nuts’ approach that can serve as a blue-print for organizational researchers and change agents interested in using external guest speakers and the personal fables they carry out, to establish collective sense-making and centring within an organizational context.

Kommunikationen inom en global industrikoncern : en kvalitativ fallstudie

Lövdahl, Robert, Ovyar-Hosseini, Jaana January 2013 (has links)
Denna undersökning syftar till att undersöka om de som är involverade i WISH på Metall-precision AB uppfattar WISH som en förbättrad och effektivare kommunikationsstrategi. Vi syftar på förbättrad i relation till hur det var innan WISH infördes, det vill säga innan år 2009. Kommunikationen inom WISH studeras främst ur ett manager perspektiv, tio av tolv inter-vjupersoner i denna undersökning har ett personalansvar. Undersökningen ägde rum på Metallprecision AB i Västersund. Sedan år 2009 pågår ett nytt förbättringsarbete, en förändringsprocess, som leder till effektiviseringar och förbättringar för Metallprecision AB. Detta förbättringsarbete kallas WISH. Vi genomförde tolv semistruk-turerade intervjuer. Resultatet visar att det finns flera olika uppfattningar om vad WISH syfte, mål och vision är för något. Alla involverade har dock en god förstålse för WISH och hur WISH praktiskt hjälper dem i deras dagliga arbete. Angående personalens olika uppfattningar av WISH syfte, mål och vision, så behöver det inte vara negativt att det råder viss variation inom rimliga gränser. Eftersom viss mångtydighet och flexibilitet främjar lärande och utveckling inom organisationen. För hård styrning via symboler och beteenden kan till och med begränsa kommunikation, därför kan det finnas styrkor med personalens olika uppfattningar enligt ovan, anser vi. Däremot kom vi fram till att det skulle finnas fördelar med att utbilda personalen mer då det gäller intranätet men även inom kommunikation eftersom vi upptäckte en del kommunikations-brister inom WISH utifrån vårt resultat. Det som idag främjar kommunikation inom WISH är delaktighet och diskussion som före-kommer på de regelbundna team och auditmötena.
