Full textAbstract:
The purpose of this study was to examine whether organizational practicesâ fairness (also known as organizational justice) and trustâ contribute to the enhancement of role breadth self-efficacy (RBSE), a form of proactive behavior. The sample consisted of 226 white-collar professionals in large and small organizations. Approximately 70% held a college degree.
An a priori path model based on theoretical literature was generated to represent causal relationships among the variables. Two paths were explored: a) the relationship among procedural justice, trust in organization, and RBSE; and b) the relationship among interactional justice, trust in supervisor, and RBSE.
Findings indicated a statistically significant relationship between procedural justice and trust in organization. The relationships between procedural justice and RBSE and trust in organization and RBSE were not significant. Interactional justice had a statistically significant relationship with trust in supervisor, but not with RBSE. The relationship between trust in supervisor and RBSE was not significant. Respondents expressed a strong trust in their organization, and a stronger trust in their immediate supervisor.
The most important discovery in this study was the statistically significant relationship between education and RBSE. Individuals with graduate degrees reported the highest level of RBSE, followed by people with Bachelor's degrees. Globalization and technology are fueling demands for ever-increasing employee skills and higher levels of education. Organizations need highly educated, proactive individuals in order to be successful. Future research should continue to investigate variables and constructs that may enhance RBSE in the workplace.Ph.

Full textAbstract:
M. Tech. (Department of Business Administration, Faculty of Management Sciences), Vaal University of TechnologyKeywords: organisational justice, procedural justice, distributive justice, interactional justice, organisational citizenship behaviour. The purpose of this study is to investigate employees’ perceptions of organisational justice and their effects on organisational citizenship behaviour. This study advocates that the way employees perceive organisational justice affects their organisational citizenship behaviour in their current organisation. The fact that employees play a central role in the realisation of an organisation’s goals makes it critical for any organisation to have employees who are willing to go beyond what is required of them. In this study, a quantitative research paradigm and an exploratory research method were used to investigate a sample size of 226 employees working at the SAPS Academy, Paarl. In order to minimise the study bias, systematic sampling was used to ensure that the sample accurately reflected the larger population (N=457). Data were collected with the aid of a structured questionnaire and the results of the correlation analysis revealed that all three dimensions of organisational justice are significantly and positively related to organisational citizenship behaviour. Organisational justice also showed a strong predictive relationship with organisational citizenship behaviour. Based on the findings of the empirical survey, it was revealed that if organisational justice practices are implemented appropriately, employees holding key positions may be likely to display more organisational citizenship behaviours. Therefore, it was recommended that, to address negative perceptions of organisational justice, a strategy should be formulated to ensure that employees are treated fairly in terms of the dimensions of organisational justice. It was also recommended that when developing and implementing such a strategy, barriers should be addressed that could: influence the availability of accurate and complete information for decision making; and influence the dissemination of information pertaining to job decisions. It is further recommended that rewards programmes be reviewed to ensure that employees will experience fairness when comparing their own payoffs with those of fellow employees and perceive just distributive justice practices. vii The study concludes by recommending that a “Code of good practice – communication policy” be developed that would enable the displaying of social sensitivity and dignified, respectful and acceptable behaviour by employees in a managerial position towards their subordinates. The findings and recommendations of this study are important to employers as they provide crucial information regarding the types of activities organisations could engage in for employees to consider them as acceptable organisational justice practices. Such involvement in acceptable organisational justice activities can improve employees’ organisational citizenship behaviour and reinforce effective and efficient service delivery in their current organisation. The implications for future research indicate that a comparative study testing the differences between different groups based on certain biographical traits, such as gender, marital status, age, educational level, income and length of service in the South African Police Service, is advisable as it would assist in determining how such biographical traits might influence the various dimensions of organisational justice. Furthermore, the study could also be expanded to include a broader national sample within the Division: Human Resource Development and other divisions within the South African Police Service.

Full textAbstract:
Telecommuting is a significant workplace innovation that allows an increasing portion of the work force to work from home or work at a location remote from the central workplace at least one-day a week. Previous studies (Bélanger, 1999; Pinsonneault & Boisvert, 2001; Potter, 2003) have outlined that the reasons for the growth of this phenomenon are found in its perceived benefits for both the telecommuter and their employer: improved productivity, organizational loyalty and belonging, job satisfaction, savings of office space, increased flexibility, improved employee morale and employee retention and attraction.
Telecommuting literature has provided models and theories about telecommuting concentrating mainly on the telecommuterâ s experiences and perspective. However, the ramifications of this practice have a broad range of potential impacts not only on the telecommuter, but also other parties in the work unit. Despite the tremendous growth in telecommuting, relatively few empirical studies (Duxbury & Neufield, 1999; Golden, 2007; Watson-Fritz, Narasimhan, and Rhee, 1998) have directly examined the creeping affect and effect of the telecommuting challenges on others in the work unit. Few studies (Bailey & Kurland, 2002; Cooper & Kurland, 2002; Golden, 2007; McCloskey & Igbaria, 2003) have investigated it from the non-telecommutersâ perspective and how it affects their work outcomes and their attitudes More importantly, no earlier studies were found that had ever investigated the effects of the telecommuting arrangement on the non-telecommuter from the organizational justice perspective, and how this affects the non-telecommuterâ s job satisfaction. This study empirically examined the affects and effects of telecommuting on non-telecommuters, and within that context, examined the extent to which organizational justice perspectives affected job satisfaction. Major findings of the study revealed that : (a) the accessibility of the telecommuter is key, even if they are working offsite, (b) job type/position plays an important role in the selection process or in some non-telecommutersâ decision to opt out of telecommuting, (c) there was lack of awareness of a formal telecommuting policy or understanding of how the policy was applied, (d) selection procedures can be biased and unfair, and (e) some non-telecommuters experienced envy and jealousy, frustration, resentment, anxiety, unfairness and anger towards telecommuting colleagues.
The results of the study also revealed that interpersonal/interactional, and distributive justice both explained the statistically significant variance in non-telecommutersâ job satisfaction. However, interpersonal/interactional justice (which focuses on the quality of interpersonal treatment individuals receive) explained a stronger statistically significant variance in the job satisfaction of non-telecommuters.Ph.

Full textAbstract:
The most recent research trend within the field of organizational justice is the study of interactional justice (Tyler & Bies, 1990; Greenberg, 1990). Most of the work conducted in this area focuses on the explanations leaders give to followers about decisions made or actions taken that frequently lead to adverse consequences or loss. These explanations are called "social accounts". While research indicates that social accounts are effective at mitigating negative reactions to adverse decisions, and improving perceptions of justice, the underlying causes remain largely unknown.
This study used the Elaboration Likelihood Model (ELM) as a theoretical base to explore what factors make an account "acceptable", and the impact that an acceptable account has on a number of organizationally relevant outcomes. Specifically, this study used an experimental design in a pay-for-performance context to assess the impact of message specificity (high vs. low) and source expertise (expert vs. non-expert), under varying conditions of outcome involvement (higher vs. lower) on the acceptability of a justification for a change in a distributive criterion that resulted in a loss. Other dependent variables investigated included perceptions of justice (procedural, interactional, and distributive fairness), attitudes (satisfaction with the trainer and the task), and behaviors (commitment to the trainer and the task, and complaints).
The results indicated that justifications delivered by the expert trainer were more acceptable than non-experts under conditions of lower involvement (except when a non-expert delivered a specific justification). This effect reversed itself, however, under higher involvement. There was a main effect of specificity such that specific justifications were more acceptable than vague justifications regardless of the level of involvement. Acceptability was positively related to all dependent measures with the exception of complaints, which had a negative relationship. Furthermore, acceptability fully mediated the impact of message specificity on trainer commitment, and partially on procedural fairness, distributive fairness (assessment), and task commitment. Acceptability fully mediated the negative impact of expertise under high involvement on procedural and distributive fairness (assessment), and interactional fairness.Ph. D.

Full textAbstract:
Body-worn cameras are a promising new development in policing. They have been linked to positive outcomes such as decreases in use of force and complaints against officers. However, this new technology has produced a number of issues that could thwart a successful body-worn camera program implementation. One issue is the extent in which officers possess positive attitudes toward using body-worn cameras. If officers do not view body-worn cameras positively, cameras may not be used to their full potential.
A promising factor that has emerged from past research in explaining attitudes toward body-worn cameras is organizational justice. Broadly, organizational justice is defined as the extent in which members of an organization are treated fairly and believe this to be the case. Organizational justice has been linked to positive organizational outcomes such as increased compliance with organizational directives and positive evaluation of organizational leadership.
The purpose of this study was to examine the relationship between organizational justice and attitudes toward body-worn cameras in police officers across three agencies. Findings indicated that there was no observable relationship between perceptions of organizational justice and attitudes toward body-worn cameras. There were a number of competing explanations for the findings, including potential measurement issues, possible intervening variables, and the possibility that there is no relationship between organizational justice and attitudes toward body-worn cameras.

There have been good arguments made for the development of aggressive affirmative action policies with the end goal of quickly moving black South Africans into corporate and high ranks within management of organisations. One of the central arguments in favour of aggressive AA policies is the risk of racial polarization post-apartheid should a quick fix not be initiated. It makes good business and economic sense for AA policies to be implemented as black consumers coupled with black managers will have the eventual end point of lower unemployment and crime, through job creation and security of the representative majority.

Full textAbstract:
This research was designed to examine the moderating effect of interactional justice on the relationship between justice constructs and organizational citizenship behavior (OCB) with organizational identification as a mediator of the influence of justice perceptions on OCB. This study was based heavily on social exchange, the norm of reciprocity, and psychological contracts between individuals and their supervisors. The study sample was comprised of respondents drawn from a crowd sourcing internet website (N = 250). Niehoff and Moorman’s Organizational Justice Scale was used to measure justice perceptions. Mael and Ashforth’s Organizational Identification Scale was used to measure the degree of the respondents’ identification with their organization; and Podsakoff, MacKenzie, Moorman, and Fetter’s OCB Scale was used to measure extra-role behaviors. Linear regression in IBM’s SPSS statistical package was used to test the proposed relationships. The results showed no support for the moderating effect of interactional justice on the relationships between justice dimensions and OCB. However, support was found for organizational identification as a mediator of the effect of interactional justice on OCB. Theoretical and managerial implications and suggestions for future research are discussed.

Full textAbstract:
This research focuses on the antecedents of perceived organizational support (POS) that may influence the perceptions held by employees of medium enterprises on organizational commitment. This research further investigates the relationship between POS and organizational commitment. The effect of power distance and in-group collectivism culture on organizational commitment in the context of the Malaysian cultural perspective has also been examined along with the effect of value congruence on organizational commitment.A two-phase sequential mixed method research design consisting of qualitative and quantitative approaches has been employed in this research. A tentative research model was first developed based on an extensive literature review followed by qualitative field study. Findings from the qualitative study were then combined with the initial model and literature review to develop the final combined model, which was then used to develop measures and instruments.In the second phase, a survey was conducted of 1000 employees in Malaysian medium enterprises in the manufacturing sector. 319 valid questionnaires were obtained. Partial Least Squares (PLS) based Structural Equation Modeling (SEM) approach was applied to test the hypotheses.The result of this research showed that supervisor support, procedural justice, interactional justice, distributive justice and both intrinsically and extrinsically satisfying job conditions have positive influences on employees‟ perception of support. POS was found to have a significant role contributing towards affective commitment. However, the influence of POS on both normative and continuance commitment was found to be non-significant in this study.This study also confirmed the influence of POS on value congruence. Both affective and normative commitment, were found to be non-significant in relation to POS. In contrast, employee–organization value congruence was found to influence continuance commitment. The analysis also found that external factors do not limit continuance commitment. National culture was found to have a different impact towards organizational commitment. The findings also revealed that the strength of the relation between POS and employees‟ commitment is negatively moderated by in-group collectivism, however power distance was found to moderate the influence of POS only on normative commitment.This research contributes to the existing literature as there has been little evidence found in the literature relating to the GLOBE culture dimensions with organizational commitment, especially in medium enterprises. This study also extends culture literature by showing that culture can act as a moderator of the relationship between POS and both affective and normative commitment. By considering value congruence, perception of support, as well as cultural orientation, this study will benefit practitioners and policy makers of medium enterprises on how to foster organizational commitment.

Full textAbstract:
In this thesis the use of enforceable undertakings is examined as a sanction for a breach in work, health and safety legislation through the lens of organisational justice. A framework of justice types - distributive, procedural and interactional - is developed and the perceptions of the three parties to the process - the regulator, the business entity and the worker as the affected third party - are explored. It is argued that the three parties perceive the sanction to be distributively unfair, but procedurally and interactionally just.

Full textAbstract:
Magister Administrationis - MAdminIn an attempt to make South Africa a more just society after the first democratic elections on 27 April 1994, the South African society had to undergo a number of radical changes which impacted the social, economical, political and educational arena. These changes have influenced recruitment, retention and turnover. Changes at leadership levels in the private and public sphere coupled with a huge exodus of highly skilled professionals are evident as topics of equality and social justice appear at the top of company agendas. Many proponents have conducted research on organisational justice and the fact that more than twenty five thousand articles have been published on job satisfaction attest to the importance of these two variables on organisational performance. In an article examining past, present and future states of organisational justice it is argued that organisational justice has the potential to explain many organisational behavioural outcome variables. An investigation of the relationship between organisational justice perceptions and work behavior found job satisfaction to be made up of a large fairness component. The rationale behind the support for the study is the argument that employees who perceive that they have been fairly treated is likely to hold positive attitudes about their work, their work outcomes and their managers. If South African organisations wish to remain competitive then organisations need to understand how perceptions of justice influence attitudes and behaviour and consequently affect the success of the organisation. Agricultural Colleges, a division of the Department of Agriculture are no exception. The Agricultural Colleges' primary aim is to provide training to its prospective communities, and is continuously being evaluated in terms of how well its academic employees achieve its vision, mission and goals. It is evident from responses to job advertisements, low morale and high turnover that most of the academic employees in Agricultural Colleges are dissatisfied with their jobs, pay, management and the institutions based on their current salary. Attracting, recruiting and retraining highly skilled, internationally marketable and mobile employees are critical factors in determining the present and future success in agricultural training in South Africa. Limited research to examine the effects of organisational justice on organisational outcomes in an environment where the workforce consists of academics is the gap this research attempts to fill. This study is designed to assess the impact of organisational justice on job satisfaction of academic employees in agricultural colleges in South Africa. Also, to determine whether biographical values influence the relationship between organisational justice and job satisfaction.

Full textAbstract:
A new viscous-inviscid semi-inverse (VISI) interaction method has been developed for predicting the flow field arising from a combination of inviscid potential flow and viscous flow. The technique involves matching the bounding velocities for each region by iteratively solving for the displacement thickness, δ*(x). The formula used to update δ*(x) after each iteration is generated by linearly perturbing the governing equations.
Application of the VISI procedure to predict the unseparated flow past a flat plate gives excellent results, producing numerical solutions essentially indistinguishable from the appropriate analytical solution in less than 0.5 seconds of CPU time on an Amdahl 5850 computer.
Application of the technique to external flow over a backward facing step (BFS) indicates that the region of strong interaction between the viscous and inviscid flows is much larger than reported for internal flow. Calculated reattachment lengths, LR, are clearly influenced by the thickness of the boundary layer upstream of the step, thicker boundary layers producing longer reattachment lengths. Good accuracy is achieved for a relatively coarse distribution of control points, and rapid convergence (< 2 seconds on the Amdahl 5850) usually occurs.
Finite-difference predictions using an elliptic code (TEACH-T), modified at the outer boundary to simulate external flow, have also been made for the BFS, largely as a basis of comparison for the VISI results. Comparison of results for the two models (VISI and TEACH) gives similar trends in LR as a function of Rh and x₈, (a measure of the displacement thickness at the step). The values of LR obtained with the VISI method, however, are 15-80% longer than those from TEACH. Direct comparison with experiments is difficult because the experimental data does not clearly identify the effects of x₈, in the resulting values of LR. Trends appear to be the same for all computed and observed cases however. Disagreement between the VISI and TEACH results is thought to be due to a combination of neglecting velocities in the recirculation region in the VISI model, and numerical error and inaccurate boundary conditions in the TEACH code.Applied Science, Faculty of

Full textAbstract:
While several Australian and international studies have explored the family lawyer-client interaction, these studies have been limited to investigations of discrete areas of the lawyerclient relationship and have been necessarily limited in their methodologies. The present study employed a quantitative empirical methodology in an Australian wide field study of 230 family lawyers and 94 clients that investigated the family lawyer-client interaction from a procedural justice framework. Using multivariate analyses, the study establishes that the Tyler and Blader two-component model of procedural justice applies in the lawyer-client dyad and is influenced by the approach of the lawyer, the emotional response of the client, and the level of co-party conflict that the client is experiencing. Further, the study gives meaning to the terms 'conciliatory and constructive' and 'adversarial' as they apply to family law dispute resolution. The study establishes a construct to measure the conciliatory and adversarial approach of family lawyers and identifies that lawyers tend to incorporate a mixture of the two into their work. The results also identify four distinct behavioural factors that characterise the two approaches: the client-centred and interest-based factors characterise the conciliatory approach; and the lawyer-directed and court-focused factors characterise the adversarial. The study found that in terms of perceptions of fairness, and feelings of satisfaction, the clients preferred the lawyers who took a client-centred and interest-based approach, but in circumstances where the clients were experiencing high-levels of conflict, or fear for the safety of their children, they also appreciated the lawyer who was lawyer-directed and court-focused. Overall, the study shows that in order to create a fair and satisfying dispute resolution service for their clients, family lawyers need to maintain a fine balance of family lawyering behaviour. On a general level, the study provides a profile of Australian family lawyers in terms of their approach to dispute resolution, their attitude towards ADR processes and their favoured negotiation styles. It also profiles family law clients in terms of their emotional adjustment to the divorce and their perceptions of the family lawyers assisting them to resolve their disputes. The study substantially expands the procedural justice theory base and has significant implications for practical family law education, government policy, family lawyering, and the ADR and collaborative law movements. The study indicates where future research could benefit these communities.

As AI develops, grows, and expands, the more benefits we can have from it. AI is used in multiple fields to assist humans, such as object recognition, self-driving cars, or design tools. However, AI could be used for more than assisting humans in their tasks. It could be employed to collaborate with humans as colleagues in shared tasks, which is usually described as Mixed-Initiative (MI) paradigm. This paradigm creates an interactive scenario that leverage on AI and human strengths with an alternating and proactive initiative to approach a task. However, this paradigm introduces several challenges. For instance, there must be an understanding between humans and AI, where autonomy and initiative become negotiation tokens. In addition, control and expressiveness need to be taken into account to reach some goals. Moreover, although this paradigm has a broader application, it is especially interesting for creative tasks such as games, which are mainly created in collaboration. Creating games and their content is a hard and complex task, since games are content-intensive, multi-faceted, and interacted by external users. Therefore, this thesis explores MI collaboration between human game designers and AI for the co-creation of games, where the AI's role is that of a colleague with the designer. The main hypothesis is that AI can be incorporated in systems as a collaborator, enhancing design tools, fostering human creativity, reducing their workload, and creating adaptive experiences. Furthermore, This collaboration arises several dynamic properties such as control, expressiveness, and initiative, which are all central to this thesis. Quality-Diversity algorithms combined with control mechanisms and interactions for the designer are proposed to investigate this collaboration and properties. Designer and Player modeling is also explored, and several approaches are proposed to create a better workflow, establish adaptive experiences, and enhance the interaction. Through this, it is demonstrated the potential and benefits of these algorithms and models in the MI paradigm.

Full textAbstract:
This is an educational design project exploring how prehospital care training can be altered to improve mental proficiency for emergency medical professionals. The London Air Ambulance performs a complex life-saving procedure known as REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) on the roadside; the only emergency medical service to do so worldwide. Teams consisting of a doctor-paramedic pairing are required to perform at their peak in extreme environments, making training for such circumstances crucial. As a result, this project strategically maps current mental processes into a framework, identifying multiple design opportunities to approach chaotic accident scenes. The framework acts as the basis for defining a curriculum, which, using Instructional Design principles, develops into a learning programme that highlights how learners experience training activities to modify communication habits and on-scene behaviour. A three-part toolkit embodies this learning programme, functioning as a sensory guide to explicitly direct attention at pre-, mid- and post-procedure interaction events between team members.

Full textAbstract:
Biomolecular simulations have been widely used in the study of protein-ligand interactions; comprehending the mechanisms involved in the prediction of binding affinities would have a significant repercussion in the pharmaceutical industry. Notwithstanding the intrinsic difficulty of sampling the phase space, hardware and methodological developments make computer simulations a promising candidate in the resolution of biophysically relevant problems. In this context, the objective of the thesis is the development of a protocol that permits studying protein-ligand interactions, in view to be applied in drug discovery pipelines.
The author contributed to the rewriting PELE, our Monte Carlo sampling procedure, using good practices of software development. These involved testing, improving the readability, modularity, encapsulation, maintenance and version control, just to name a few. Importantly, the recoding resulted in a competitive cutting-edge software that is able to integrate new algorithms and platforms, such as new force fields or a graphical user interface, while being reliable and efficient. The rest of the thesis is built upon this development.
At this point, we established a protocol of unbiased all-atom simulations using PELE, often combined with Markov (state) Models (MSM) to characterize the energy landscape exploration. In the thesis, we have shown that PELE is a suitable tool to map complex mechanisms in an accurate and efficient manner. For example, we successfully conducted studies of ligand migration in prolyl oligopeptidases and nuclear hormone receptors (NHRs). Using PELE, we could map the ligand migration and binding pathway in such complex systems in less than 48 hours. On the other hand, with this technique we often run batches of 100s of simulations to reduce the wall-clock time. MSM is a useful technique to join these independent simulations in a unique statistical model, as individual trajectories only need to characterize the energy landscape locally, and the global characterization can be extracted from the model. We successfully applied the combination of these two methodologies to quantify binding mechanisms and estimate the binding free energy in systems involving NHRs and tyorsinases. However, this technique represents a significant computational effort.
To reduce the computational load, we developed a new methodology to overcome the sampling limitations caused by the ruggedness of the energy landscape. In particular, we used a procedure of iterative simulations with adaptive spawning points based on reinforcement learning ideas. This permits sampling binding mechanisms at a fraction of the cost, and represents a speedup of an order of magnitude in complex systems. Importantly, we show in a proof-of-concept that it can be used to estimate absolute binding free energies.
Overall, we hope that the methodologies presented herein help streamline the drug design process.Las simulaciones biomoleculares se han usado ampliamente en el estudio de interacciones proteína-ligando. Comprender los mecanismos involucrados en la predicción de afinidades de unión tiene una gran repercusión en la industria farmacéutica. A pesar de las dificultades intrínsecas en el muestreo del espacio de fases, mejoras de hardware y metodológicas hacen de las simulaciones por ordenador un candidato prometedor en la resolución de problemas biofísicos con alta relevancia. En este contexto, el objetivo de la tesis es el desarrollo de un protocolo que introduce un estudio más eficiente de las interacciones proteína-ligando, con vistas a diseminar PELE, un procedimiento de muestreo de Monte Carlo, en el diseño de fármacos. Nuestro principal foco ha sido sobrepasar las limitaciones de muestreo causadas por la rugosidad del paisaje de energías, aplicando nuestro protocolo para hacer analsis detallados a nivel atomístico en receptores nucleares de hormonas, receptores acoplados a proteínas G, tirosinasas y prolil oligopeptidasas, en colaboración con una compañía farmacéutica y de varios laboratorios experimentales. Con todo ello, esperamos que las metodologías presentadas en esta tesis ayuden a mejorar el diseño de fármacos.

Context. Procedural Terrain Generation refers to the algorithmical creation of terrains with limited or no user input. Terrains are an important piece of content in many video games and other forms of simulations. Objectives. In this study a tile-based approach to creating endless terrains is investigated. The aim is to find if real-time performance is possible using the proposed method and possible performance increases from utilization of the GPU. Methods. An application that allows the user to walk around on a seemingly endless terrain is created in two versions, one that exclusively utilizes the CPU and one that utilizes both CPU and GPU. An experiment is then conducted that measures performance of both versions of the application. Results. Results showed that real-time performance is indeed possible for smaller tile sizes on the CPU. They also showed that the application benefits significantly from utilizing the GPU. Conclusions. It is concluded that the tile-based approach works well and creates a functional terrain. However performance is too poor for the technique to be utilized in e.g. a video game.

Full textAbstract:
Context. Procedural content generation (PCG) refers to algorithmical creation of game content (e.g. levels, maps, characters). Since PCG generators are able to produce huge amounts of game content, it becomes impractical for humans to evaluate them manually. Thus it is desirable to automate the process of evaluation. Objectives. This work presents an automatic method for evaluation of procedural level generators for 2D platform games. The method was used for comparative evaluation of four procedural level generators developed within the research community. Methods. The evaluation method relies on simulation of the human player's behaviour in a 2D platform game environment. It is made up of three components: (1) a 2D platform game Infinite Mario Bros with levels generated by the compared generators, (2) a human-like bot and (3) quantitative models of player experience. The bot plays the levels and collects the data which are input to the models. The generators are evaluated based on the values output by the models. A method based on the simple moving average (SMA) is suggested for testing if the number of performed simulations is sufficient. Results. The bot played all 6000 evaluated levels in less than ten minutes. The method based on the SMA showed that the number of simulations was sufficiently large. Conclusions. It has been shown that the automatic method is much more efficient than the traditional evaluation made by humans while being consistent with human assessments.

Full textAbstract:
Parameter estimation is one of the central issues in neural spatial interaction modelling.
Current practice is dominated by gradient based local minimization techniques. They
find local minima efficiently and work best in unimodal minimization problems, but
can get trapped in multimodal problems. Global search procedures provide an
alternative optimization scheme that allows to escape from local minima. Differential
evolution has been recently introduced as an efficient direct search method for
optimizing real-valued multi-modal objective functions (Storn and Price 1997). The
method is conceptually simple and attractive, but little is known about its behaviour in
real world applications. This paper explores this method as an alternative to current
practice for solving the parameter estimation task, and attempts to assess ist robustness,
measured in terms of in-sample and out-of-sample performance. A benchmark
comparison against backpropagation of conjugate gradients is based on Austrian
interregional telecommunication traffic data. (authors' abstract)Series: Discussion Papers of the Institute for Economic Geography and GIScience

Full textAbstract:
Procedurally implemented synthetic audio could offer greater interactive potential for audio in games than the currently popular sample based approach does. At the same time, synthetic audio can reduce storage requirements that using sample based audio results in. This study examines these potentials, and looks at one game interaction in depth to gain knowledge around if players prefer and chooses objects with interactive sounds generated through procedurally implemented modal synthesis, over objects with traditionally implemented sample based sound. An in-game environment listening test was created where 20 subjects were asked to throw a ball, 35 times, at a wall to destroy wall tiles and reveal a message. For each throw they could select one of two balls; one ball had a modal synthesis sound that varied in pitch with how hard the ball was thrown, the other had a traditionally implemented sample based sound that did not correspond with how hard it was thrown but one of four samples was called at random. The subjects were then asked questions to evaluate how realistic they perceived the two versions to be, which they preferred, and how they perceived the sounds corresponding to interaction. The results show that the modal synthesis version is preferred and perceived as being more realistic than the sample based version, but wether this was a deciding factor in subjects’ choices could not be determined.

Full textAbstract:
As realistic virtual environments become more important, it is interesting to examine procedural generation. In this work, plausibility of virtual furniture layouts was evaluated in a perceptual study comparing layouts by a professional human interior designer with layout variants rearranged by a C# algorithm. It attached related furniture sides at specified distances in groups. Rasterized furniture footprints were tested, and layouts without overlaps between furniture or their clearance areas were accepted. The algorithm was inspired by Germer and Schwarz (Computer Graphics Forum, 28(8), pp. 2068–2078. 2009), and the evaluation methodology by Yu et al. (ACM Transactions on Graphics, 30(4), pp. 1–11. 2011). The algorithm was run by a Unity tool which placed furniture models in a virtual 3D room. Human-made layouts were also visualized and all layouts presented for 2 and 10 seconds with participants tasked to assess if they were human-made or not. The algorithm fulfilling side-based spatial relation constraints and clearance area constraints did not prove to produce as plausible virtual layouts as those by a human designer, but these constraints significantly improved the perceptual plausibility versus semi-arbitrary furniture placement with only wall-placement constraints for relevant furniture. Perceived orderliness of both human-made and generated layouts was significantly positively correlated with plausibility. The evaluation also provided knowledge of what characteristics are perceived as tells of procedural generation rather than human interior design.Då realistiska virtuella miljöer blir viktigare är det intressant att undersöka processuell generering. I detta arbete utvärderades trovärdigheten av virtuella möbellayouter i en perceptuell studie som jämförde layouter gjorda av en inredningsdesigner med layoutvariationer omarrangerade av en C#-algoritm. Den satte ihop relaterade möbelsidor på specificerade avstånd i grupper. Rasteriserade möbelavtryck testades och layouter utan överlapp mellan möbler eller deras friytor accepterades. Algoritmen var inspirerad av Germer och Schwarz (Computer Graphics Forum, 28(8), s. 2068–2078. 2009) och utvärderingen av Yu et al. (ACM Transactions on Graphics, 30(4), s. 1–11. 2011). Ett Unity-verktyg placerade möbler i ett virtuellt 3D-rum. Designer-layouter visualiserades också och alla layouter visades i 2 & 10 sekunder för deltagare som bedömde om de var arrangerade av människa eller ej. Algoritmen som uppfyllde spatiala sidorelationsvillkor och villkor för fria ytor visade sig inte producera lika trovärdiga virtuella layouter som de gjorda av en människa, men dessa villkor förbättrade trovärdigheten signifikant jämfört med semi-godtycklig möbelplacering med enbart väggplaceringsvillkor för relevanta möbler. Uppfattad nivå av ordning var för både de mänskliga och genererade layouterna signifikant positivt korrelerad med deras trovärdighet. Utvärderingen gav också kunskap om vad som uppfattas som tecken för datorgenerering snarare än mänsklig inredning.

Full textAbstract:
We conducted a contingency analysis to evaluate if a sequential relation between social initiations and positive social responses increased for both therapists and children with autism following a conditioned reinforcement procedure. Participants included child-therapist dyads, which were previously identified as having low rapport. These dyads were observed prior to and following an intervention designed to establish therapists' social behavior as a reinforcer. Sessions consisted of unstructured play between the therapist and child. Results from a Yule's Q analysis show that both the child and adult positive responding to the others' social initiations increased following the intervention. Findings highlight the reciprocal effects of therapist-child interactions as well as the effectiveness of establishing social attention as a reinforcer via an operant discrimination training procedure.

Full textAbstract:
The thesis deals with the way student groups translate when simulating interactions between translators and clients, using risk management concepts as tools for describing their decisions. The research aims are: 1) to explore how the use of peer-group interaction in a simulated setting affects students’ ways of managing risk while translating, and 2) to study whether translators have any identifiable pattern of behavior of risk management and effort distribution. A two-cycle experiment involving two roles, the translator and the simulated client, was carried out with a class of translation students to test the effects of the main variable of peer-group interaction. Performance data were collected with screen recordings and think-aloud protocols. Additional data are collected through pre-and-post-experiment questionnaires and interviews with student subjects. The research analyzes of the translators’ rendition processes, codes the problems they face, observe the translation procedures they consider and finally adopt, and looks into the justifications for their procedures, in order to interpret their risk management.La presente investigación analiza cómo los estudiantes de traducción gestionan el riesgo mientras traducen en un entorno simulado en el que se representa la relación traductor-cliente. Los objetivos de la investigación son: 1) analizar cómo la interacción de grupo de pares en un entorno simulado altera la forma en que los estudiantes gestionan el riesgo durante la traducción, y 2) averiguar si los traductores individuales tienen un patrón de comportamiento identificable en lo que respecta a la gestión de riesgo y a la distribución del esfuerzo. Se realizó un experimento de dos ciclos que incluyó dos roles (el traductor y el cliente simulado) con un grupo de estudiantes de traducción para evaluar los efectos de la interacción en un grupo de pares. Se recolectaron datos adicionales por medio de cuestionarios previos y posteriores al experimento, así como también por medio de entrevistas con los sujetos. Con el fin de interpretar su gestión del riesgo, la investigación analiza los procesos de traducción de los traductores, clasifica los problemas que enfrentaron, considera los procedimientos de traducción que tuvieron en cuenta y los que, finalmente, decidieron usar, y busca la razón por la que usaron dichos procedimientos.

Full textAbstract:
Context. Animation of character locomotion is an important part of computer animation and games. It is a vital aspect in achieving believable behaviour and articulation for virtual characters. For games there is also often a need for supporting real-time reactive behaviour in an animation as a response to direct or indirect user interaction, which have given rise to procedural solutions to generate animation of locomotion. Objectives. In this thesis the performance aspects for procedurally generating animation of locomotion within real-time constraints is evaluated, for bipeds and quadrupeds, and for simulations of several characters. A general pose-driven feedback algorithm for physics-driven character locomotion is implemented for this purpose. Methods. The execution time of the locomotion algorithm is evaluated using an automated experiment process, in which real-time gait simulations of incrementing character population count are instantiated and measured, for the bipedal and quadrupedal gaits. The simulations are measured for both serial and parallel executions of the locomotion algorithm. Results. Simulations of up to and including 100 characters are performance measured providing an overview of the slowdown rate when increasing the character count in the simulations, as well as the performance relations between bipeds and quadrupeds. Conclusions. The experiment concludes that the evaluated algorithm on its own exhibits a relatively small performance impact that scales almost linearly for the evaluated population sizes. Due to the relatively low performance impacts it is thus also concluded that for future experiments a broader measurement of the locomotion algorithm that includes and compares different physics solvers is of interest.

Includes bibliographies.The dissertation concerns the procedure of teacher supervision as presently conducted at the University of Cape Town's School of Education, and suggests ways in which this can be improved. It is argued that teacher education should be situated in the paradigm of Action Research, and within that, in the approach known as Participant Observation. The language of the classroom is chosen as the means whereby classroom practices can be investigated. A detailed account is provided of a full sequence of clinical supervision, and use is made of complete lesson and subsequent interview transcriptions in this account. The methodological techniques of participant observation, interviews, 'triangulation' procedures and fieldnotes to supplement the analysis of transcripts and interviews, are used. In addition, three different ways of analysing classroom language are described, viz . discourse analysis, insightful observation and coding schemes, and their appropriacy for teacher supervision purposes assessed. Finally, teacher conclusions are drawn regarding an effective model for supervision. It is suggested that FIAC (Flanders' Interaction Analysis Categories) be used in combination with lesson transcriptions, and stress is laid on the need for teacher trainees and trainers to observe at all times the criteria for participant observation. Suggestions are put forward concerning possible implementation of recommendations made, and the need for future research in this area is emphasised.

Spel idag kräver en enorm mängd arbetstimmar för att skapas, därför behövs alltid sätt att spara tid och automatisera processer. Algoritmer för polygoniseringen av skalärfält, som Marching Cubes, har under de senaste åren blivit ett allt vanligare tillvägagångssätt för att automatiskt generera terräng. Scenkomplexiteten och kraven för visuell kvalitet i dagens spel ökar ständigt. Därmed kommer också kravet för prestandaeffektiva renderingsmetoder. Deferred rendering är en renderingsmetod som kan hantera scener med stora mängder ljuskällor och hög scenkomplexitet samtidigt. För att undersöka integreringen mellan procedurellt skapad terräng och en deferred rendering pipeline, skapades en applikation i DirectX 11 för att undersöka implementeringen och potentiella optimeringar av denna integration.Detta projekt handlar om slumpmässig procedurell skapning av digital terräng för bruk inom datorspel, och hur man i denna kontext kan ta nytta av en grafikmotor som använder renderingstekniken deferred rendering.

Full textAbstract:
Il collasso di diverse colonne, caratterizzate da danneggiamenti simili, quali ampie fessure fortemente inclinate ad entrambe le estremità dell’elemento, lo schiacciamento del calcestruzzo e l’instabilità dei ferri longitudinali, ha portato ad interrogarsi riguardo gli effetti dell’interazione tra lo sforzo normale, il taglio ed il momento flettente.
Lo studio è iniziato con una ricerca bibliografica che ha evidenziato una sostanziale carenza nella trattazione dell’argomento.
Il problema è stato approcciato attraverso una ricerca di formule della scienza delle costruzioni, allo scopo di mettere in relazione lo sforzo assiale, il taglio ed il momento; la ricerca si è principalmente concentrata sulla teoria di Mohr.
In un primo momento è stata considerata l’interazione tra solo due componenti di sollecitazione: sforzo assiale e taglio. L’analisi ha condotto alla costruzione di un dominio elastico di taglio e sforzo assiale che, confrontato con il dominio della Modified Compression Field Theory, trovata tramite ricerca bibliografica, ha permesso di concludere che i risultati sono assolutamente paragonabili.
L’analisi si è poi orientata verso l’interazione tra sforzo assiale, taglio e momento flettente. Imponendo due criteri di rottura, il raggiungimento della resistenza a trazione ed a compressione del calcestruzzo, inserendo le componenti di sollecitazione tramite le formule di Navier e Jourawsky, sono state definite due formule che mettono in relazione le tre azioni e che, implementate nel software Matlab, hanno permesso la costruzione di un dominio tridimensionale. In questo caso non è stato possibile confrontare i risultati, non avendo la ricerca bibliografica mostrato niente di paragonabile.
Lo studio si è poi concentrato sullo sviluppo di una procedura che tenta di analizzare il comportamento di una sezione sottoposta a sforzo normale, taglio e momento: è stato sviluppato un modello a fibre della sezione nel tentativo di condurre un calcolo non lineare, corrispondente ad una sequenza di analisi lineari.
La procedura è stata applicata a casi reali di crollo, confermando l’avvenimento dei collassi.

Research has shown that individuals with autism spectrum disorder (ASD) lack the skills to develop meaningful friendships. One procedure that has been demonstrated to have positive effects for teaching social skills among individuals with ASD is the Teaching Interaction procedure. Yet, there is minimal research evaluating the effects of the Teaching Interaction procedure on adults diagnosed with ASD. The purpose of this study was to evaluate the effects of the Teaching Interaction procedure on increasing targeted social skills of young adults diagnosed with autism spectrum disorder utilizing a multiple baseline design across participants and replicated across behaviors. Prior to intervention, the participants displayed low levels of the three targeted social skills. Targeted social skills were sharing, eye contact, and initiating a greeting. A multiple probe design across participants and replicated across behaviors resulted in all participants acquiring all three targeted social skills. The data indicated that each participant maintained the targeted social skills across settings over time. Social validity questionnaires completed by the participants’ teachers indicated that the Teaching Interaction procedure was age appropriate, helped the participants engage with others more independently, and that outcomes were satisfactory.

Full textAbstract:
El camp d'Experiència d'Usuari consta d'una àmplia gamma d'aspectes diferents sobre la interacció amb productes o serveis. L'experiència d'usuari difereix del paradigma objectiu basat en el rendiment, centrant-se en un punt de vista més ampli on les necessitats d'usuaris, els desitjos i les fantasies tenen un paper important en el procés de presa de decisions dels usuaris. L'enfocament d' hipòtesi i validació utilitzant anàlisi quantitatiu té dificultats per tractar, d'una manera estructurada, altres tipus d'informació que aspectes estrictament relacionats amb l'ús dels productes (per exemple les emocions) on els resultats obtinguts són efímers i complexos.Els aspectes d'experiència d'usuari que impliquen sentiments relacionats amb necessitats inherents, desitjos i fantasies s'anomenen informació subjectiva sobre l'experiència. Per obtenir aquesta classe d'informació, l'experiència d'usuari s'analitza segons la relació psicològica entre usuaris i productes o serveis. Aquesta tesi descriu el canvi de paradigme que proposa la psicologia constructivista i la seva pertinència per a l'aplicació en l'obtenenció d'informació subjective sobre l'experiència d'usuari en les primeres fases del disseny de producte. Primerament, una visió de conjunt general del punt de vista proposat presenta les bases de la psicologia constructivista aplicables al camp de l'experiència d'usuari. Després, differents estudis exploratoris il·lustren, amb exemples, com s'haurien d'utilitzar aquestes tècniques com eines d'obtenció d'informació subjectiva:
- La tècnica dels paisatges experiencials utilitza la graella cognitive, una aproximació alternativista al constructivisme, per obtenir informació sobre la resposta dels consumidors a un cert grup de productes i els requeriments d'ús.
- El procediments de restricció utilitzen tècniques d'escalament (aproximació discursiva al constructivisme) per aconseguir informació nuclear sobre valors que una persona té. Aplicat a disseny de producte serveix per augmentar el nivell de precisió, obtenint informació que relaciona atributs emocionals, funcionals i físics del producte.
- El mètode de generació de metàfores sensorials es pot considerar una aproximació retòrica al constructivisme i utilitza productes, objectes i contextos com vehicles per transmetre coneixement tàcit.
- La visualització de necessitats i desitjos latents és una aproximació narrativa al constructivisme. Utilitza presentacions de vídeo per desvelar comportaments d'interaccions futures que compleixen els desitjos i les aspiracions dels usuaris.
Les tècniques per a l'obteció d'informació subjectiva sobre l'experiencia d'usuari proposades en aquesta tesi doctoral (SEGIT) emergeixen de l'anàlisi de les avantatges i febleses dels estudis exploratoris anteriors. Es poden considerar com un conjunt de tècniques (exploratives i projectives) per ser utilitzades durant el procés de disseny com a eina inspiradora per guiar el procés creatiu (una tècnica de generació d'idees d'experiència per desenvolupar nous conceptes d'interacció) i un model per a la validació de resposta futura dels consumidors. La informació obtinguda amb el mètode de SEGIT s'analitza per a propòsits inspiradors i informatius:
- Des d'un punt de vista inspirador, el conjunt de tècniques proporcionen aspectes clau per al procés d'inspiració. Les tècniques exploratòries permeten obtenir idees detallades i justificades i les tècniques projectives conceptes amb un nivell alt d'abstracció i coherència al mateix temps.
- Des d'un punt de vista informatiu, aquest conjunt de tècniques es poden utilitzar per obtenir informació sobre la preferència de compra dels consumidors. Alhora que analitza diferents variables que afecten la fiabilitat dels resultats obtinguts.
En conclusió, la visió sobre el disseny de la interacció presentat en aquesta tesi doctoral i les tècniques proposades mostren un camí optimista per explorar amb el propòsit de millorar l'acceptació de noves tecnologies en la vida quotidiana.
The field of User Experience (UX) consists of a wide range of different aspects about the interaction with products or services. User experience differs from the performance-based objective paradigm, focusing on a wider point of view where users needs, desires and fantasies have a role in the users decision-making process. Quantitative analysis and hypothesis and validation approaches have difficulties to deal, in a structured way, with information other than that, which is strictly related to aspects regarding product usage (i.e. emotions and affect, social interaction) and the results obtained are ephemeral and complex to measure.
The aspects of user experience that involve feelings related to inherent needs, desires and fantasies are called subjective experience information. To obtain this kind of information, user experience analyzes the psychological relationship between users and products or services. This thesis describes constructivist psychology and its relevance for user experience research in early stages of product development. First, a general overview of the proposed point of view introduces constructivist psychology to user experience practitioners. Then several exploratory studies illustrate, with examples, how these techniques should be used as subjective user experience information gathering tools:
- The experience landscapes technique use the repertory grid as an alternativist approach to constructivism for gathering information about consumers' response to a certain group of products and extract users' experience requirements.
- The tightening procedure uses laddering techniques (discursive approach to constructivism) to get core information, the values a person holds. In order to increase the level of accuracy, obtaining design relevant information that relates emotional, functional and physical product attributes.
- The sensory metaphor generation method can be considered a rhetorical approach to constructivism and uses products, objects and contexts as carriers of meaning of subjective experiences.
- The visualization of inner needs and desires technique is a narrative approach to constructivism. It uses video presentations to unveil future interactions behaviours that fulfil users' desires and aspirations.
The Subjective Experience Gathering and Inspiring Techniques proposed in this PhD thesis (SEGIT) emerges from the analysis of the strengths and weaknesses of those exploratory studies. It can be considered a set of techniques (explorative and projective techniques) to be used throughout the design process as an inspirational tool to guide the creative process, a generation technique of experience ideas to develop interaction concepts and a model for consumers' future response validation. The information obtained with the SEGIT method is analyzed for inspirational and informational purposes:
- From an inspirational point of view, the set of techniques provide key aspects of the inspiration process in relation to exploratory (detailed and complete ideas) and projective techniques (concepts with high level of abstraction and coherence at the same time). In addition, results show that different aspects like the participants' linguistic abilities and practitioners' guiding skills affect consistency.
- From an informational point of view this set of techniques can be used to obtain subjective experience construing profiles about consumers' product preference. At the same time the results show how variables like participants' cognitive complexity of consumers' response and the cognitive structure of the valuation process affect its reliability.
In conclusion, the approach to interaction design presented by this research and the proposed techniques for inspirational and informational purposes show an optimistic path to explore with the aim to help designers to bring peoples' sensorial experience and technology closer together.

Full textAbstract:
Games can be used to convey meaning and communicate messages. While there is ample research on games' expressive capacities, how players' backgrounds impact game interpretation has thus far been under-explored. This study explores this gap by way of testing an expressive game and discerns if there is a relationship between how people experience a game and their personal background and current state of mind. To engage this question, we conducted a player study. We developed the abstract, metaphorical game “Lorn” intended for this purpose. The game together with an online survey, intended to assess players' background and state of mind, was distributed to potential participants. After having played the game, the participants shared their interpretation of the message in the game and their experiences and feelings they experienced while playing. 15 people participated in the player study. The result indicates there are differences in how people interpret a message depending on their personal background and their current state of mind.Spel kan användas för att förmedla både budskap och mening. Trots att det finns omfattande forskning på hur man kan uttrycka sig med spel, så är forskning kring hur spelares bakgrund påverkar deras tolkning bristfällig. Den här studien utforskar detta genom att testa ett “expressivt spel” och urskilja om det finns någon koppling mellan hur människor upplever ett spel och deras personliga bakgrund och sinnesstämning. Vi utförde en spelarstudie för att undersöka den här frågan. För detta ändamål utvecklade vi det abstrakta, metaforiska spelet “Lorn”. Tillsammans med en online enkät, som ämnade att ta reda på spelarnas bakgrund och sinnesstämning, distribuerade vi spelet till potentiella deltagare. Efter att ha spelat spelet delgav deltagarna sina tolkningar av betydelsen, sina upplevelser av Lorn, och vilka känslor de kände när de spelade spelet. 15 personer deltog i studien. Våra resultat indikerar att det finns skillnader i hur människor tolkar budskap beroende på deras personliga bakgrund och sinnesstämning.

Full textAbstract:
Les travaux de cette thèse proposent une nouvelle approche pour le guidage assisté par robots d'aiguilles flexibles pour des procédures percutanées. La méthode est basée sur l'utilisation d'une rotation de l'aiguille avec un rapport cyclique variable pour réaliser une insertion avec des arcs de rayons de courbure différents. Elle combine un retour visuel avec une stratégie de planification adaptative pour compenser les incertitudes du système et les perturbations. Par rapport aux approches présentées précédemment dans la littérature, la stratégie de planification en boucle fermée est adaptée à des scènes dynamiques qui présentent des changements de position des obstacles et de la cible. Cette approche a été implémentée sur un système robotique et les résultats obtenus in vitro confirment tout l'intérêt de cette techniqueThis thesis proposes a robot-assisted approach for automatic steering of flexible beveled needles in percutaneous procedures. The method uses duty-cycled rotation of the needle to perform insertion with arcs of adjustable curvature, and combines closed-loop imaging feedback with an intraoperative motion replanning strategy to compensate for system uncertainties and disturbances. Differently from previous approaches, the closed-loop replanning strategy is suitable for dynamic scenes that present changes of obstacles and target positions. Indeed, we implemented the proposed system using a robotic manipulator, and the results obtained from in vitro tests confirmed the viability of our method

Full textAbstract:
In this paper we view learning as an unconstrained non-linear minimization
problem in which the objective function is defined by the negative log-likelihood
function and the search space by the parameter space of an origin constrained product
unit neural spatial interaction model. We consider Alopex based global search, as
opposed to local search based upon backpropagation of gradient descents, each in
combination with the bootstrapping pairs approach to solve the maximum likelihood
learning problem. Interregional telecommunication traffic flow data from Austria are
used as test bed for comparing the performance of the two learning procedures. The
study illustrates the superiority of Alopex based global search, measured in terms of
Kullback and Leibler's information criterion.

Full textAbstract:
Control room operating crews are a crucial component in maintaining the safety of nuclear power plants. The primary support to operators during disturbances or emergencies are numerous emergency operating procedures. Further support is provided by reoccurring crew training in which the crews practice on handling anticipated disturbances in full-scale simulators. Due to the complexity of nuclear power plants and the small number of previous accidents to learn from, every possible accident scenario cannot be covered by the procedures and hence not trained on in the simulator. This raises the question of how operators can be prepared and able to cope with unexpected events by other means. This thesis investigates the possibilities of operating crews to act flexibly in situations where stable responses in the form of prescribed actions sequences from procedures cannot be applied. The study is based on the safety research paradigm of resilience engineering and the four cornerstones of resilience; learning, monitoring, anticipating, and responding (Hollnagel, 2011). The meaning and applicability of the resilience cornerstones were examined by interviewing a domain expert at the time employed by the OECD Halden Reactor Project. Subsequently, eight semi-structured interviews with operator training personnel at a Swedish nuclear power plant provided the main data of this study. This study shows that the resilience cornerstones were applicable to the work of nuclear power plant crews during emergency operations. In addition, the study provides findings regarding which artefacts (e.g. procedures) or crew characteristics (e.g. ways of communicating) support the cornerstone functions. The base thesis is that procedures always shall be used, but in situations where an operator perceives that no procedure is applicable, the crew have an opportunity to discuss the problem to come up with some other solution, i.e. act flexibly. Some trainers argued that the room for flexibility is there when needed, but it is not as certain how much flexibility and what kind of flexibility the operators are given. However, it does not seem like the flexibility, or lack of flexibility, given to operators is in itself the most problematic issue in the preparation of crews for unexpected events. Instead, this study identified several other problems of training and everyday work that could negatively affect crews’ capability to handle unexpected events. On the other hand, the trainers highlighted communication and teamwork to be important when the unexpected strikes and that much focus have been shifted towards such issues in training. Hence this can be claimed to be an important contribution given by the training today in successfully handling unforeseen events.
