Dataflow Analysis and Workflow Design in Business Process ManagementSun, Xiaoyun January 2007 (has links)
Workflow technology has become a standard solution for managing increasingly complex business processes. Successful business process management depends on effective workflow modeling, which has been limited mainly to modeling the control and coordination of activities, i.e. the control flow perspective. However, given a workflow specification that is flawless from the control flow perspective, errors can still occur due to incorrect dataflow specification, which is referred to as dataflow anomalies.Currently, there are no sufficient formalisms for discovering and preventing dataflow anomalies in a workflow specification. Therefore, the goal of this dissertation is to develop formal methods for automatically detecting dataflow anomalies from a given workflow model and a rigorous approach for workflow design, which can help avoid dataflow anomalies during the design stage.In this dissertation, we first propose a formal approach for dataflow verification, which can detect dataflow anomalies such as missing data, redundant data, and potential data conflicts. In addition, we propose to use the dataflow matrix, a two-dimension table showing the operations each activity has on each data item, as a way to specify dataflow in workflows. We believe that our dataflow verification framework has added more analytical rigor to business process management by enabling systematic elimination of dataflow errors.We then propose a formal dependency-analysis-based approach for workflow design. A new concept called "activity relations" and a matrix-based analytical procedure are developed to enable the derivation of workflow models in a precise and rigorous manner. Moreover, we decouple the correctness issue from the efficiency issue as a way to reduce the complexity of workflow design and apply the concept of inline blocks to further simplify the procedure. These novel techniques make it easier to handle complex and unstructured workflow models, including overlapping patterns.In addition to proving the core theorems underlying the formal approaches and illustrating the validity of our approaches by applying them to real world cases, we provide detailed algorithms and system architectures as a roadmap for the implementation of dataflow verification and workflow design procedures.

Sociology in South Africa is characterised by two issues: &lsquo / negations&rsquo / and theoretical &lsquo / extraversion&rsquo / . In the light of the foregoing claim, the study sought to investigate the underlying epistemological features of sociology curriculum in one of the South African universities. In investigating these issues, the thesis relies on the notion of &lsquo / authentic interlocutors&rsquo / put forward by Archie Mafeje. Literature on transformation of the social sciences in (South) Africa was reviewed. Methodologically, the study assumes a qualitative approach. In order comprehensively to understand the problem under investigation, in-depth interviews were conducted along with a review of course outlines of the selected department of sociology / these, in turn, were subjected to content analysis. Interviewees included, respectively, academic members of staff and postgraduate students. The study concludes by highlighting the &lsquo / ontological disconnect&rsquo / , on the part of South African sociologists, not only with their immediate environment but the rest of the African continent. In maintaining this view, it argues that their ontological and epistemological standpoints only succeed in highlighting their cultural affinity with Euro-American perspectives.

'n Evaluasie van die substansafhanklikheids-program van die Suid-Afrikaanse Polisiediens / deur Marina du PlooyDu Plooy, Marina January 2004 (has links)
Background:
As result of the restructuring of the South African Police Services during 1994 as well as other
factors, Police Social Work Services decided to shift the focus from reactive services to more
proactive, personnel capacity building programmes. At the end of 1999 , 15 of these programmes
were already developed. Although basic evaluation instruments were included in some of the
programme packages, the need arose to determine either the effect of the programmes on the
participants or the cost-efficiency of the interventions scientifically. This led to the launch of the
PCBP project and the Evaluation of the Substance Dependency study in November 2001. This
form part of the evaluation of the comprehensive personnel capacity building research project.
Objectives:
The primary aim of the study was to determine the effect of the Substance Dependency
Programme on SAPS personnel's knowledge, attitude and behaviour.
Method:
In the research, the comparison group pre-test and post-test design and triangulation were used. Six
measurement scales and a presenter's evaluation questionnaire were developed and completed by
217 experimental group respondents, 47 comparison group respondents and 10 presenters.
Results:
Through the triangulation of measurement it was determined that the Substance Dependence
Programme had a practical significant effect on the respondent's knowledge, attitude and behaviour.
It is thus an effective tool in the hand of Police Social Work Services, that empower police
members and lead to productivity and enhanced their personal well-being. / Thesis (M.A. (MW))--North-West University, Potchefstroom Campus, 2005.

Priklausomybių gramatikos taikymas lietuvių kalbos apdorojime / Dependency Grammar in Lithuanian Language ProcessingGrigonytė, Gintarė 26 May 2006 (has links)
Lithuanian language is quite in an early stage of language processing. And therefore has a high demand on automated tools like taggers, parsers, word sense disambiguators etc. During the last 10 years only a few researchers were attempting to create a parser for Lithuanian language. However none of them are used in practices nowadays. The process of designing and implementing rule based parser for Lithuanian language is presented in this paper. Rules and constraints of the formal grammar follow the principles of Dependency Grammar. Necessary language recourses were made up at the Computational Centre of Linguistics. Research area analysis and overview of the most popular methodologies is presented here as well. Syntax parser of the Lithuanian language was evaluated against the Gold Standard and gave 80,2 % of accuracy of in recognizing parts of the sentence.

Analysis of some risk models involving dependenceCheung, Eric C.K. January 2010 (has links)
The seminal paper by Gerber and Shiu (1998) gave a huge boost to the study of risk theory by not only unifying but also generalizing the treatment and the analysis of various risk-related quantities in one single mathematical function - the Gerber-Shiu expected discounted penalty function, or Gerber-Shiu function in short. The Gerber-Shiu function is known to possess many nice properties, at least in the case of the classical compound Poisson risk model. For example, upon the introduction of a dividend barrier strategy, it was shown by Lin et al. (2003) and Gerber et al. (2006) that the Gerber-Shiu function with a barrier can be expressed in terms of the Gerber-Shiu function without a barrier and the expected value of discounted dividend payments. This result is the so-called dividends-penalty identity, and it holds true when the surplus process belongs to a class of Markov processes which are skip-free upwards. However, one stringent assumption of the model considered by the above authors is that all the interclaim times and the claim sizes are independent, which is in general not true in reality. In this thesis, we propose to analyze the Gerber-Shiu functions under various dependent structures. The main focus of the thesis is the risk model where claims follow a Markovian arrival process (MAP) (see, e.g., Latouche and Ramaswami (1999) and Neuts (1979, 1989)) in which the interclaim times and the claim sizes form a chain of dependent variables. The first part of the thesis puts emphasis on certain dividend strategies. In Chapter 2, it is shown that a matrix form of the dividends-penalty identity holds true in a MAP risk model perturbed by diffusion with the use of integro-differential equations and their solutions. Chapter 3 considers the dual MAP risk model which is a reflection of the ordinary MAP model. A threshold dividend strategy is applied to the model and various risk-related quantities are studied. Our methodology is based on an existing connection between the MAP risk model and a fluid queue (see, e.g., Asmussen et al. (2002), Badescu et al. (2005), Ramaswami (2006) and references therein).
The use of fluid flow techniques to analyze risk processes opens the door for further research as to what types of risk model with dependency structure can be studied via probabilistic arguments. In Chapter 4, we propose to analyze the Gerber-Shiu function and some discounted joint densities in a risk model where each pair of the interclaim time and the resulting claim size is assumed to follow a bivariate phase-type distribution, with the pairs assumed to be independent and identically distributed (i.i.d.). To this end, a novel fluid flow process is constructed to ease the analysis.
In the classical Gerber-Shiu function introduced by Gerber and Shiu (1998), the random variables incorporated into the analysis include the time of ruin, the surplus prior to ruin and the deficit at ruin. The later part of this thesis focuses on generalizing the classical Gerber-Shiu function by incorporating more random variables into the so-called penalty function. These include the surplus level immediately after the second last claim before ruin, the minimum surplus level before ruin and the maximum surplus level before ruin. In Chapter 5, the focus will be on the study of the generalized Gerber-Shiu function involving the first two new random variables in the context of a semi-Markovian risk model (see, e.g., Albrecher and Boxma (2005) and Janssen and Reinhard (1985)). It is shown that the generalized Gerber-Shiu function satisfies a matrix defective renewal equation, and some discounted joint densities involving the new variables are derived. Chapter 6 revisits the MAP risk model in which the generalized Gerber-Shiu function involving the maximum surplus before ruin is examined. In this case, the Gerber-Shiu function no longer satisfies a defective renewal equation. Instead, the generalized Gerber-Shiu function can be expressed in terms of the classical Gerber-Shiu function and the Laplace transform of a first passage time that are both readily obtainable.
In a MAP risk model, the interclaim time distribution must be phase-type distributed. This leads us to propose a generalization of the MAP risk model by allowing for the interclaim time to have an arbitrary distribution. This is the subject matter of Chapter 7. Chapter 8 is concerned with the generalized Sparre Andersen risk model with surplus-dependent premium rate, and some ordering properties of certain ruin-related quantities are studied. Chapter 9 ends the thesis by some concluding remarks and directions for future research.

Compounding Effects of Dysphoria and Mood Stability on Eyewitness IdentificationROUNDING, KEVIN 23 September 2010 (has links)
To date, research on the effect of depressive symptomatology on victim-witness identification is scarce even though depressive symptomatology is highly prevalent in the victim-witness experience. Furthermore, being a victim-witness often instigates the use of counselling services, which could cause a shift in affect, and applying mood dependent memory theories, any change in affect should be detrimental to eyewitness accuracy. Still, individuals suffering from subclinical depression, or dysphoria, have exhibited heightened perceptual skills, and depressed affect exhibits remarkable stability over time. Therefore, I theorized that: (1) dysphoric people’s heightened sensitivity and motivation towards accurate understanding may result in more accurate eyewitness identifications, and (2) individuals who express stable levels of dysphoria should have greater eyewitness identification accuracy than should people with stable levels of nondysphoria, with stable levels of severe depressive symptomatology, or with unstable depressive symptomatology. In Study One, 132 students were randomly assigned to one of three autobiographical mood inductions: a positive, negative, or neutral/control. Following this manipulation, participants completed 12 experimental trials each consisting of a target exposure, a 30-second distraction task, and lastly, a six-person simultaneous line-up. Higher levels of dysphoria were associated with greater overall identification accuracy and that temporary mood conferred an advantage only when participants recalled highly sad memories. In Study Two, 173 participants were exposed to 12 target faces at a first session and returned two-to-four weeks later to identify these faces from 12 six-person simultaneous line-ups. Individuals who exhibited stable levels of dysphoria from eyewitness event to the line-up task performed significantly better on the simultaneous line-ups than all of the other groups. Among those exhibiting unstable dysphoria, people whose depressive symptomatology improved were almost as accurate as those who had stable dysphoria. These results support the need for victim-witnesses to receive immediate help to stabilize or improve depressive symptomatology not just for their mental well-being but also to preserve eyewitness accuracy. / Thesis (Master, Psychology) -- Queen's University, 2010-09-23 13:11:50.153
