Testo completoAbstract (sommario):
In light of the global shift to remote work that was prompted by the Covid-19 pandemic - the relevance and use of Electronic Performance Monitoring (EPM) significantly escalated across all sectors. However, the most recent comprehensive literature review on the topic by Ravid et al. (2020) pointed out significant gaps in how EPM is perceived by knowledge-based employees. In line with those defined gaps, we raised two research questions, regarding what the perceptions of knowledge-based workers are towards the implementation and dissemination of EPM techniques, and whether the workplace context (home/office) has an effect on knowledge-based worker’s perceptions towards it. In this paper, we take a critical approach relying on a theory-based typology of EPM characteristics and build on the organizational control theory by elaborating on the technology-mediated control concept. We follow the constructivist grounded theory approach developed by Charmaz (2008) and the data was collected via 20 semi-structured interviews. The key findings of this research showed similarities as well as differences in how knowledge-based employees perceive EPM in contrast to other types of workforce. While overall the perceptions on EPM are negative, they can to some extent be alleviated by introducing a justifiable purpose, being transparent, allowing control over monitoring, and setting clear limits. Moreover, we provided insights into the perceptions of knowledge-based workers in response to EPM within the context of working from home. In such a context, knowledge-based workers show more resistance to EPM techniques and higher expectations of privacy, transparency, and appropriate data handling. Lastly, the authors provided avenues for further research including cross-cultural perspective, access to data, and ethicality and legality of EPM.

Testo completoAbstract (sommario):
More than a century ago in their definitive work “The Right to Privacy” Samuel D. Warren and Louis D. Brandeis highlighted the challenges posed to individual privacy by advancing technology. Today’s workplace is characterised by its reliance on computer technology, particularly the use of email and the Internet to perform critical business functions. Increasingly these and other workplace activities are the focus of monitoring by employers.
There is little formal regulation of electronic monitoring in Australian or United States workplaces. Without reasonable limits or controls, this has the potential to adversely affect employees’ privacy rights.
Australia has a history of legislating to protect privacy rights, whereas the United States has relied on a combination of constitutional guarantees, federal and state statutes, and the common law. This thesis examines a number of existing and proposed statutory and other workplace privacy laws in Australia and the United States.
The analysis demonstrates that existing measures fail to adequately regulate monitoring or provide employees with suitable remedies where unjustifiable intrusions occur. The thesis ultimately supports the view that enacting uniform legislation at the national level provides a more effective and comprehensive solution for both employers and employees.
Chapter One provides a general introduction and briefly discusses issues relevant to electronic monitoring in the workplace. Chapter Two contains an overview of privacy law as it relates to electronic monitoring in Australian and United States workplaces. In Chapter Three there is an examination of the complaint process and remedies available to a hypothetical employee (Mary) who is concerned about protecting her privacy rights at work. Chapter Four provides an analysis of the major themes emerging from the research, and also discusses the draft national uniform legislation. Chapter Five details the proposed legislation in the form of the Workplace Surveillance and Monitoring Act, and Chapter Six contains the conclusion.

Testo completoAbstract (sommario):
The perceptions of employees regarding electronic surveillance in the workplace were studied using a mixed method approach. The change that permeates society and organisations have not escaped public FET institutions in South Africa. These changes such as computerisation of work and the employment of electronic surveillance, have implications for management, control, privacy, productivity and trust in the workplace. Yet, public FET institutions are not performing to the expected standards. Surveillance of work and employees at these institutions are interventions of management to ensure organisational goals are achieved. Despite the prevalence of electronic surveillance in the workplace, employee perceptions and their lived experiences thereof are seldom reported. Published research barely focuses on employees’ perceptions of electronic surveillance in the workplace, and instead offers a perfunctory look at the perceptual dimensions. Employees’ perceptions reflects their lived experiences in the workplace and yield a foundational understanding of workplace dynamics and organisational behaviour. The perceptions of employees regarding electronic surveillance were viewed through the lens of quantitative and qualitative analysis to give statistical and thick descriptions respectively to augment better understanding. The study therefore provides a descriptive account of employees’ perceptions of electronic surveillance and its effects. Specifically the study examined employee perceptions of electronic surveillance as a control measure of management, as an intrusion of employee privacy and impacting on the trust relationship and productivity. An extensive review of the literature provided the basis for the research questions and eight hypotheses were proposed. A survey, by means of an electronic questionnaire, was conducted to test the hypotheses using a random sample of employees at three public FET institutions in the Eastern Cape Province, South Africa. The results are presented followed by a discussion, conclusions and limitations. Suggestions and recommendations for future research are also indicated. The central thesis of the study is presented, namely that electronic surveillance is experienced as a measure of management to control workers and that privacy as well trust, as an element of the employment relationship, are influenced by it. Further findings indicated that there are no statistically significant differences in the responses of the three job categories namely lecturers, managers and administration and support staff. Interviews were also conducted and the data from the interviews reported the depth and breadth of the perceptions of a small sample of employees who related their experiences and situations in terms of the key themes of electronic surveillance as control and an intrusion of their right to privacy, trust and productivity. The findings indicate that acceptance of electronic surveillance is contingent upon contextual factors and the meaning people assign to their situations. Privacy concerns were limited to personal information, fairness and dignity. The link between electronic surveillance and control and discipline is reported in the responses. The findings indicate that perceptions of electronic surveillance as managerial control is related to the lived experiences of employees. Employees voiced positive perceptions of electronic surveillance in cases where management clearly communicates the purpose to the employees. The study of the subjective experiences of employees in workplaces under electronic surveillance thus helped to illuminate the intricacies of employment relationships in the changing world of work. The study findings widen the knowledge base on organisational behaviour and is essential for human resources management and organisational development interventions. Human rights and ethics are part of the sense making process when employees construct social reality. Management and control is redefined in various terms and has implications for change management strategies and organisational development practises in globalising and network society. The study raises the critical question whether electronic surveillance as an adjunct for bureaucratic control is still relevant in a changing world of work where good faith, trust and confidence are still highly valued. The insights into the role of trust in the employment relationship is important for managing public institutions in complex settings. Management must be aware of the differences in the lived experiences of employees when dealing with workplace issues.

Awarded by:University of New South Wales. School of Industrial Relations and Organisational Behaviour, 2005. http://handle.unsw.edu.au/1959.4/22026.
Testo completoAbstract (sommario):
Drawing upon case studies of three organisations operating six call centres in Australia, this thesis explores the manifestations and interplay of employee resistance and accommodation in response to five facets of employer control: electronic monitoring; repetitious work; emotional control; the built environment; and workplace flexibility. Accommodation refers to the ways workers protect themselves from and adapt to the pressures that make up their day-to-day experiences of work. Accommodation, unlike resistance, which implies opposition to control, may superficially resemble consent to control. I argue that resistance and accommodation are not polar opposites; rather they are both reflections of the conflict and tensions that lie at the heart of the employment relationship. At the study sites, employees utilised resistance and accommodation both separately and concurrently. An explanation of these seemingly contradictory responses and of the links among accommodation individual resistance and collective resistance lies in the concept of ???self???. In this thesis, ???self??? refers to workers??? perceptions of fairness, dignity and autonomy. I examine how these notions frame worker discontent and promote employee solidarity. ???Everyday resistance???, a concept first developed by Scott (1985) in relation to peasant struggles, is employed to highlight the existence of subterranean struggles in workplaces that otherwise appear to be harmonious. At the study sites, everyday resistance was a multi-faceted, widely employed strategy whose strength lay primarily in its immediate impact. There was, however, no necessary sequential development from accommodation, through everyday resistance to overt, formal forms of conflict. What was evident was that multiple responses to employer control could co-exist and inhibit or promote one another. But it was through organised collective resistance that more formalised gains were made and widely held grievances addressed. I suggest that, although everyday resistance may lay the groundwork for more formal struggles, one should not conclude that traditional collective resistance is ???genuine??? resistance and everyday resistance is simply a second-best prelude to it. Although conflict is always present, its intensity differs. If we are to understand the complexity of worker responses to managerial control, we need to expand the theoretical frameworks within which we analyse and interpret conflict.

Processing personal data may be an incidental consequence but difficult to avoid in the day to day operations of the employment relationship. Privacy in the context of the employment relationship is not a precise term but a bundle of not very specifically defined rights and expectations. Generally the main focus of privacy rights apply to the restraint of power by the state as defined in Section 14 of the South African Constitution. It could be applied to the employee and employer relationship. The existence of other public interest may substantively reduce the scope of such privacy rights. [...]

Testo completoAbstract (sommario):
The purpose of this exploratory study was to examine resident, family member and staff perceptions of electronic monitoring and their effect on resident rights. The sample consisted of 53 nursing home residents, 104 staff and 25 family members, in the Dallas Fort Worth metroplex, from a nursing facility in which residents utilize video cameras in their rooms (Nursing Facility 1), two nursing facilities that have video cameras in their common rooms areas (Nursing Facility 2 and 3) and a nursing facility that does not utilize video cameras (Nursing Facility 4). The interview questions and self-administered surveys were in regard to the participant's perceptions of electronic monitoring, perceived risks and benefits of video cameras, awareness of resident rights and consciousness of potential risks to resident rights. Data were analyzed using a mixed methods approach using both ATLAS t.i and SAS. Study findings revealed that residents, family members and staff are aware of the potential benefits of electronic monitoring in nursing facilities. While respondents are hesitant to have electronic monitoring in resident rooms, they are interested in utilizing electronic monitoring in common areas. While residents and staff believe that electronic monitoring compromises resident rights, family members believe resident rights are protected. Different types of staff have different perceptions of electronic monitoring. Those staff members that are more directly involved in resident care are less accepting of electronic monitoring compared to staff that have episodic visits with residents. Among staff members, nursing facilities with prior experience with electronic monitoring are less accepting of electronic monitoring. Further studies are needed to enhance this research.

Thesis (MPA)--Stellenbosch University, 2011.ENGLISH ABSTRACT: Human beings are constantly confronted with change because their current situation is continually being questioned. In order to change the way humans behave, it is necessary to change the mindset of those who will be influenced by new ideas. Stellenbosch Municipality faces a dilemma because the current management of its employee attendance is having a negative impact on its daily operations – service delivery is becoming an increasingly serious concern because the inability to manage employees’ daily attendance results in inefficient and ineffective rendering of services to citizens. This research addresses the question of whether the change from a manual attendance register to a biometric time and attendance system would more effectively ensure the availability of Municipal employees to improve basic service delivery. Moreover, the dilemma Stellenbosch Municipality faces concerns the monitoring of employees on a daily basis, including the availability of an attendance register for audit purposes. A questionnaire was used to examine the situation and obtain responses from employees who make use of both the manual attendance register and the biometric time and attendance device. It was established that the use of the manual attendance register caused certain problems, although it has served a monitoring purpose for more than 30 years. At the time of answering the questionnaire, some respondents requested the implementation of an electronic system with real-time capability to remove any doubt concerning the confirmation of employee attendance. The feedback from the questionnaire confirms: - the unreliability of a human-dependent employee attendance register; - that delivery of basic services can only be done on condition of the availability of employees who report for duty; and - that the use of the manual attendance system creates unrecoverable losses. The inability of employees to maintain their manual attendance registers led to the recommendation that: - a mechanised system needs to be implemented to reduce administration procedures and to secure compliance and an unqualified audit.
AFRIKAANSE OPSOMMING: Mense word voortdurend met verandering gekonfronteer omdat hul huidige situasie gedurig bevraagteken word. Ten einde die manier waarop mense optree te verander, is dit nodig om die geestesingesteldheid van diegene wat deur nuwe idees beïnvloed sal word te verander. Die Munisipaliteit Stellenbosch staan voor ’n dilemma omdat die huidige bestuur van sy werknemerbywoning ’n negatiewe uitwerking op sy daaglikse werksaamhede het – dienslewering word ’n al ernstiger saak weens die onvermoë om werknemers se daaglikse bywoningsresultate by onbekwame en ondoeltreffende lewering van dienste aan dorpsbewoners te bestuur. Hierdie navorsing ondersoek die vraagstuk of die omskakeling van ’n bywoningsregister per hand na ’n biometriese tyd- en bywoningstelsel die beskikbaarheid van munisipale werknemers meer effektief sal verseker om basiese dienslewering te verbeter. Hierbenewens het die dilemma van die Munisipaliteit Stellenbosch te doen met die daaglikse monitering van werknemers, waaronder die beskikbaarheid van ’n bywoningsregister vir ouditeringsdoeleindes. ’n Vraelys is gebruik om die situasie te ondersoek en reaksies te verkry van werknemers wat van die bywoningsregister per hand sowel as die biometriese tyd- en bywoningsinstrument gebruik maak. Daar is vasgestel dat die bywoningsregister per hand sekere probleme veroorsaak het, hoewel dit langer as 30 jaar ’n moniteringsdoel gedien het. Met die beantwoording van die vraelys het party respondente die implementering van ’n elektroniese stelsel met intydse vermoë versoek om enige twyfel omtrent die bevestiging van werknemerbywoning te verwyder. Die terugvoering van die vraelys bevestig: - die onbetroubaarheid van ’n menslik afhanklike werknemerbywoningsregister; - dat lewering van basiese dienste slegs kan plaasvind op voorwaarde van die beskikbaarheid van werknemers wat vir diens aanmeld; en - dat die gebruik van die bywoningstelsel per hand onverhaalbare verliese skep. Die onvermoë van werknemers om hul bywoningsregisters per hand by te hou het gelei tot die aanbeveling dat: - ’n gemeganiseerde stelsel geïmplementeer moet word om administratiewe prosedures te verminder; en om ’n ongekwalifiseerde ouditering te verseker.

Shamsul, Ramesh Zakir bin. "Video exposure monitoring as a tool in workplace exposure assessment". Thesis, University of Iowa, 2010. https://ir.uiowa.edu/etd/738.
Testo completoAbstract (sommario):
Video exposure monitoring (VEM) consists of taking video recording of a worker performing a task at the same time while personal monitoring is performed using a direct-reading instrument. The video and the exposure data are then merged and synchronized and analyzed together. The industrial hygienist conducting the VEM is able to identify any high level of exposure and note the time when the excessive level happened. The corresponding task of the worker is then identified based from the video shot taken at the same time as the exposure data.
The objective of this thesis was to study the implementation of a low cost means of conducting VEM in workplaces with hazardous chemicals in use, by utilizing commercially-available direct reading instruments, a digital video camera, and either off-the-shelf software or freeware downloadable from the internet. It was intended that VEM done by such means would still have the same ability of conveying workplace exposure results and, at the same time, capable of pinpointing work areas where controls could be initiated to reduce excessive levels of contaminants.

Testo completoAbstract (sommario):
Wind turbine converters used in multi-megawatt machines will operate at high voltages, particularly in future generations of wind turbines where direct connections to a HVDC backbone are made. Given the pressure to achieve high power densities in a converter to minimise the space utilised, the pressure on the high voltage insulation system to be reduced in size to the minimum possible is great. With it, this brings the increased risk of electrical discharge within the system insulation. The PhD project has therefore examined a number of issues: a) Evaluation of the risks posed to HV power electronic systems from electrical discharge: on the basis of a literature survey, discussions with converter manufacturers and the application of standard HV engineering models, the risks to a power electronic system in the wind turbine application will be assessed. b) Theoretical assessment of potential monitoring techniques: Given the risks that have been described in (a) above, the possible ways in which monitoring could be applied will be investigated. Each risk will be assessed to confirm that discharge mechanism that results in failure/damage will produce some form of measurable signal (whether this is through voltage, current acoustic, RF etc.). c) Experimental assessment of sensors for use in HV power electronic monitoring: Using a HV source within an anechoic chamber (to provide RF and acoustic noise reduction), a range of HV defects that could occur in power electronic systems will be simulated. The ability of suitably characterised sensors to detect the defects will be assessed. The research has then focus on RF detection of PD to develop a measurement method that can be applied to operating s power electronic converters (EPC).Firstly the RF emissions of several types of discharge have been studied in depth alongside the study of the effect of the environmental pressure on the signature of the different discharges. Then, the knowledge gathered was applied to perform and verify the effectiveness of RF measurements to online detect PD within operating EPC. Finally the applicability of the RF technique was verified for the detection of other electrical discharges (non-PD like) as electrical tracking.

Testo completoAbstract (sommario):
This study of 112 students from a university in Northeast Florida was designed to determine if there was a relationship between self-monitoring, job structure, and job selection. It was hypothesized that high self-monitors would choose structured jobs more than would low self-monitors. It was also hypothesized that low self-monitors would choose less structured jobs than would high self-monitors. These hypotheses were evaluated by using Snyder's Self-Monitoring Scale (1974) to classify participants as high or low self-monitors and by asking participants to role play being applicants offered one of two jobs (structured versus unstructured). Results of this experiment do not support these hypotheses. Limitations, plausible alternative explanations, and directions for future research are discussed.

Thesis (LLM)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: The monitoring of electronic communication is likely to face all employers sooner or later. The rapid advancement in technology aimed at helping to monitor electronic communication, makes it easier than ever before for employers to monitor the electronic communications of their employees. There are important questions to consider when dealing with the topic of monitoring electronic communication. Examples include "mayan employer legally monitor electronic communications?" and "how does monitoring affect the employee's right to privacy?" This thesis is an attempt to answer these and other related questions by analysing, inter alia, South African legislation, the Constitution and case law, as well as comparing the law as it applies in the United Kingdom and the United States of America. The analysis and conclusion offered in this thesis aim to provide theoretical consideration to academics and practical application for employers that are faced with the reality of monitoring electronic communications.
AFRIKAANSE OPSOMMING: Alle werkgewers sal waarskynlik die een of ander tyd met die monitering van elektroniese kommunikasie gekonfronteer word. Die snelle voortuitgang in tegnologie wat daarop gemik is om te help met die monitering van elektroniese kommunikasie, maak dit vir werkgewers makliker as ooit tevore om sodanige kommunikasies van hulle werknemers te monitor. Daar is egter belangrike vrae wat oorweeg moet word wanneer die onderwerp van monitering van elektroniese kommunikasie ter sprake kom. Voorbeelde hiervan is "mag 'n werknemer regtens elektroniese kommunikasies monitor?" en "hoe raak monitering die werknemer se reg tot privaatheid?" Hierdie tesis is 'n poging om hierdie en ander verwante vrae te beantwoord deur die ontleding van, onder andere, Suid-Afrikaanse wetgewing, die Grondwet en die reg soos deur hofuitsprake ontwikkel, sowel as vergelyking van die reg soos wat dit van toepassing is in die Verenigde Koninkryk en die Verenigde State van Amerika. Die ontleding en gevolgtrekking wat in hierdie tesis aangebied word, is gemik op die verskaffing van teoretiese oorweging aan akademici en praktiese toepassing vir werkgewers wat met die realiteit van die monitering van elektroniese kommunikasies gekonfronteer word.

On propose dans ce mémoire un nouveau type de capteur pour la mesure des fonctions respiratoires et cardiaques à des fins médicales. Le système offre la possibilité de mesurer le rythme respiratoire et la profondeur de respiration et de transmettre les données vers une station locale pour une analyse plus poussé et un diagnostic. Le capteur proposé est basé sur une approche électromagnétique où on utilise deux antennes posées sur la cage thoracique du patient. Lorsque le patient inspire et expire l’air avec ses poumons, le diamètre de la cage thoracique de ce dernier va augmenter et par conséquent la distance entre les deux antennes aussi. Le système mesure l’écart relatif entre les deux pour extraire le rythme respiratoire. Le point clé du capteur est d’encoder le signal de respiration sous forme de différence de phase entre l’onde émise et l’onde reçue conférant au système une bonne immunité contre les bruits des signaux externes. Le design a été implémenté sur un PCB (46mm x 46mm) pour fournir une preuve de concept de la méthode proposée. Les tests ont été conduits sur trois sujets de deux sexes et d’âges distincts. Les données mesurées démontrent que le système fonctionne sur différentes morphologies physiques. Finalement, le capteur a été capable de recueillir avec grande précision le rythme respiratoire et même la fréquence cardiaque.We propose in this project a wearable electronic Patch Radar sensor that can monitor respiration rate and respiration depth continuously in real-time and transmit data to a base station for analysis. The device relies on a two-antenna configuration. Both antennas are bent to the patient chest, and when the patient breathes, the mechanical movement of the chest wall changes the distance between them. The system measures the relative distance between the antennas to extract the respiration pattern. The key feature of the sensor is that it transduces respiration movements to phase shifts in RF wave signals which make it very robust against external interferences. The design was implemented on a PCB (46mm x 46mm) to demonstrate a proof of concept for the proposed device. The system was able to acquire respiration signals and even cardiac frequency. Experimental results are presented for three different subjects, an adult male and female and a child. The data gathered gives enough sensitivity and accuracy to state that the device can work with different physical morphologies.

Testo completoAbstract (sommario):
Literature survey and correspondence with industrial sector shows that No-Fault-Found (NFF) is a major concern in through life engineering services, especially for defence, aerospace, and other transport industry. There are various occurrences and root causes that result in NFF events but intermittent interconnections are the most frustrating. This is because it disappears while testing, and missed out by diagnostic equipment. This thesis describes the challenging and most important area of intermittent fault detection and health monitoring that focuses towards NFF situation in electronics interconnections. After introduction, this thesis starts with literature survey and describes financial impact on aerospace and other transport industry. It highlights NFF technologies and discuss different facts and their impact on NFF. Then It goes into experimental study that how repeatedly intermittent fault could be replicated. It describes a novel fault replicator that can generate repeatedly IFs for further experimental study on diagnosis techniques/algorithms. The novel IF replicator provide for single and multipoint intermittent connection. The experimental work focuses on mechanically induced intermittent conditions in connectors. This work illustrates a test regime that can be used to repeatedly reproduce intermittency in electronic connectors whilst subjected to vibration.

Testo completoAbstract (sommario):
In order to remain effective in an increasingly digital workplace, many organizations have shifted towards the automatic and electronic collection of employee performance data. For example, employees completing computer-based training may be monitored to collect objective performance information for either developmental or administrative purposes. Though this allows for more objective employee feedback and evaluation, little remains known about the effect of pervasive electronic monitoring on key self-regulatory processes which underlie learning. This study was designed with this gap in mind and explores the relationship between electronic monitoring type (developmental or administrative), goals, and feedback perceptions, feedback usage, and learning. In order to understand this relationship, the current study extends classical theories of performance management and self-regulation to supplement emerging research on electronic monitoring. Results of this experiment suggest that monitoring purpose does not have a strong impact on state goals. Monitoring purpose, however, may affect feedback perceptions. Using the results of this study, evidence-based recommendations can be made for the theoretical understanding and practical of monitored training.

Includes bibliography.The objective of this thesis is to determine whether Adaptive Noise Cancelling can be used successfully in determining the state of machine elements. In addition, this thesis was used to gain experience in real-time computing. This was done by designing and building a real-time machine monitoring package using an IBM PC and a TMS 320C25 digital signal-processing chip manufactured by Texas Instruments. To determine which adaptive algorithm should be used in the package, experiments were carried out on a computer with different types of adaptive noise cancelling algorithms, the two main ones being the Least-Mean-Squares (LMS) and Recursive-Least-Squares (RLS) algorithms.

Testo completoAbstract (sommario):
With the growth of the Internet, computational systems have become more and more complex, often including complicate interconnected networks of autonomous components. The need to bring some organisational structure into autonomous systems becomes urgent, as this allows regulating the behaviour of the different autonomous components to ensure their objectives are aligned with the holistic objectives of the system.
Normative Systems are one of the mechanisms that can be applied to define and enforce acceptable behaviour within distributed electronic systems which should comply with some (human) regulations. One of the requirements to effectively implement Normative Systems is to be able to assess, at runtime, the state of the normative environment. Existing lines of research have already tried to tackle this issue on some simple scenarios. However, more complex scenarios may appear, for instance, scenarios where the normative context is not static, but it expands and contracts as new norms are added to the institution and removed from it respectively.
As in human legal systems, it is easy to foresee that some of these electronic normative environments will not be static. They should be able to evolve through time as regulations change, effectively adapting to new situations and behaviours. Under these conditions, a monitoring system must be able to continue computing the state of the normative environment at runtime, as often we can not afford to perform the changes on the normative context off-line. Furthermore, it must be guaranteed the monitoring system can keep producing states of the normative environment that are consistent with the changes performed on the normative context. For instance, if a norm has been removed from the normative context, it does not make sense anymore to compute normative states where the norm has been violated.
In this thesis we present NoMoDEI, a normative monitoring framework for dynamic Electronic Institutions. We formalize and develop an extended normative framework and architecture to cope with scenarios where the normative context is dynamic, therefore norms can be added, removed and updated. The operations are to be performed at run-time, without having to stop computing the normative state. The normative states computed are consistent with the expansion and contraction operations.
NoMoDEI is introduced in three steps. First, we formally define the operations to be supported in order to allow for expanding and contracting the normative context. Then, we instantiate the formal operations, providing implementation details. Finally, we demonstrate our framework by applying it to two use cases: E-health systems and waste-water management on a river basin.Amb l'expansió d'Internet els sistemes computacionals han esdevingut més complexos, sovint incorporant complicades xarxes interconnectades de components autònoms. Es per això que la necessitat d'incorporar estructures organitzacionals en el sistemes autònoms s 'accentua, donat que aquestes estructures permeten regular el comportament dels diferents components autònoms, tot assegurant que els seus objectius es troben alineats amb els objectius generals del sistema. Els Sistemes Normatius (i.e. Normative Systems) són un dels mecanismes que podem aplicar per definir i imposar patrons acceptables de comportament dintre de sistemes electrònics distribuïts. Això esdevé especialment important quan el sistema es troba regimentat per regulacions (normalment humanes). Un dels requeriments per implementar Sistemes Normatius és ser capaços de determinar, en temps d'execució, l'estat de l'entorn normatiu. Existeixen línies de recerca que ja han tractat aquest problema en alguns escenaris simples. El món real però ens ofereix escenaris més complexes, com per exemple, escenaris on el context normatiu no és estàtic, si no que s'expandeix i contrau a mesura que noves normes són afegides o eliminades de la institució. Tal com passa als sistemes legals humans, és fàcil preveure que alguns contextos normatius electrònics no seran estàtics. Aquests contextos haurien de ser capaços d'evolucionar a través del temps a mesura que les regulacions canvien, adaptant-se a noves situacions i comportaments. Sota aquestes condicions, un sistema de monitorització ha de ser capaç de continuar calculant l'estat de l'entorn normatiu en temps d'execució, ja que sovint no ens podem permetre realitzar els canvis a l'entorn normatiu aturant el procés de monitorització. És més s'ha de garantir que el sistema de monitorització sigui capaç de continuar produint es tats de l’entorn normatiu de forma consistent amb els canvis realitzats. Per exemple, el fet d'eliminar una norma fa que no tingui gaire sentit continuar calculant es tats normatius on aquesta norma ha es tat violada. A aquesta Tesi presentem NoMoDEI, una infraestructura de monitorització normativa per institucions electròniques dinàmiques. Formalitzem i desenvolupem una infraestructura de monitorització normativa estesa capaç d'operar en escenaris on el context normatiu es dinàmic. Es a dir, diverses normes poden ser introduïdes, eliminades o actualitzades del context normatiu en qualsevol moment. Aquestes operacions s'han de poder realitzar en temps d'execució, es a dir, sense deixar de calcular l'estat normatiu. Es més, els estats normatius calculats han de ser consistents amb les respectives operacions d'extensió o contracció del context. Durant la Tesi presentem NoMoDEI en tres passos. Primer proporcionem una definició formal de les operacions que la infraestructura ha de suportar per permetre expandir i contraure el context normatiu. A continuació instanciem aquestes operacions proporcionant detalls d'implementació. Finalment demostrem que la nostra infraestructura pot ser aplicada a casos d'ús del món real introduint dos casos: sistemes de salut electrònics (i.e. E-health) i sistemes de tractament d’aigües residuals a la conca d’un riu

Jabir, Saad A. A. "Thick film electronic ceramic sensors for civil structures health monitoring". Thesis, Edinburgh Napier University, 2011. http://researchrepository.napier.ac.uk/Output/4475.
Testo completoAbstract (sommario):
Buildings, roads, bridges and structures in general suffer many kinds of damages due to overstress caused by settlements of foundations, high winds, dynamic forces, passing traffic, vibration and unexpected external loads beyond the safe design forces. The damages manifest itself by cracks, falling of plaster and render uneven roads and some time complete collapse. The cost of maintaining and fixing damages caused by the above is quite high for the building and construction industry. The same phenomenon is common to many other structures like airplanes, wind turbine and machinery in general. Structural Health Monitoring (SHM) is the engineering branch, which aims to give, at every moment during the life of a structure, a diagnosis of the "state" of the constituent materials, of the different parts of a structure. The state of the structure must remain in the domain specified in the design, although this can be altered due to usage or due to normal aging by the action of the environment, and by accidental events. By using special electronic sensors to monitor the unexpected high concentration of stresses or changes of these stresses throughout the life of the structure and pavement, reduces the cost of maintenance and repair. Historic buildings would also benefit from using such sensors to monitor the overstress in the old and frugally stones and bricks. The sensors can be embedded in the lime mortar joints and an electronic meter is used periodically to check for any unusual overstress during the life of the building. The main aim of the proposed research project is to investigate the possibility of using thick-film technology stress sensors in masonry, concrete and building materials in general to monitor overstress and instability throughout the life of the structures. The sensors could be used in brick, block, stone, and concrete and they could be mounted on the surface or embedded in the materials. There are many research studies on strain gauge devices in structural monitoring; Thick Film (TF) piezo-resistive sensors are proposed as a direct alternative to the widely used metal Foil Strain Gauges (FSG). Due to the low cost of TF sensors, their ease of use, suitability to integrate electronics on board, and to have different geometrical shapes, they could be deployed at different locations in a building, road or be distributed in arrays. This offers the continuous monitoring of stresses at any time by using a data logger on two points on the surface or by using wireless electronic transmission. In this research, new thick film screen-printed ceramic piezo-resistive sensor has been developed and characterized as discrete device for deployment on surface of a structure and embedded into the structure during building material curing or after structure erection. The sensor response on different building materials has been experimented and compared. Mechanical and electronic simulation tools were used to characterise the sensor and to choose an adequate interface electronic circuit. The experimental results of the simulated sensor and circuitry, showed the suitability of the sensor to be embedded in building materials during curing period and on erected structures. Materials used were wood, concrete, brick and plaster. In addition, the overall linearity of response of the sensors applied on building material surface was asserted which makes the technology a candidate for a more wide deployment in SHM field.

Yun, Raymond. "Persistent Workplace Energy Savings and Awareness through Intelligent Dashboards: Monitoring, Advice, Comparison, Control and Automation". Research Showcase @ CMU, 2014. http://repository.cmu.edu/dissertations/636.
Testo completoAbstract (sommario):
Commercial buildings consume at least 18% of the total electrical energy used in the United States. Over 2.8 billion dollars are wasted every year due to computers being left on during the night and weekend. Yet up to 40% of the plug-load energy consumption can be reduced by behavior change. In the field of Human Computer Interaction (HCI), recent intervention studies have identified that monitoring and controls can motivate more environmentally-focused behavior in residences, where the occupants also have a financial interest. These studies, however, have not adequately addressed behavior in office environments, neither been thoroughly quantified for impact nor fully explored control strategies. This dissertation addresses these limitations through the development of an Intelligent Dashboard for Occupants (ID-O) that provides diverse feedback (selfmonitoring, advice, comparison) and control (remote and automated control) features. With an ID-O, through a variety of interventions, one can explore 1) energy conservation, 2) energy awareness, and 3) persistent energy savings. Three intervention strategies are considered in this dissertation in the following order: • Feedback; • Feedback and on-line control; • Feedback, on-line control and automated control The first two give rise to the following expectation, namely, that there is an increase in energy conservation, energy awareness and persistent energy savings, even after the intervention has been removed. The third strategy suggests that it will (relatively) provide the greatest increase in energy conservation with a (relative) reduction in energy awareness and persistent energy savings, after the intervention has been removed. These then are the hypotheses that underlie this dissertation. To thoroughly investigate the effectiveness of feedback and control interfaces, the ID-O dashboards were deployed in a large office building over a period of nine months. Eighty employees were recruited and their baseline data was collected for fourteen weeks. With four groups of 20 employees, three different configurations were tested alongside one control group – one with only feedback (self-monitoring, advice, and comparison), one with feedback and on-line control, and one with feedback, on-line and automated control. The dashboards were in place for thirteen weeks, and then removed for eleven weeks, allowing for measurements of user electricity consumption before, during and after the availability of an Intelligent Dashboard. During the interventions, the more features that were offered, the greater savings that were achieved. After the interventions were removed, all dashboard groups persistently saved energy with only a slight decrease in savings. Surveys were conducted at the end of the pre, during and post interventions. Between the during- and post-interventions, the biggest awareness increase was found for the group with only feedback and the group with feedback and on-line control. A relatively low increase was measured for the group with feedback, on-line and automated control. The following results were demonstrated: • Provision of feedback (self-monitoring, advice, and comparison) through energy dashboards increases 1) energy conservation, 2) energy awareness, and 3) persistent energy savings, even after the intervention has been removed. • Introduction of feedback and on-line controls have greater 1) energy conservation, 2) energy awareness and 3) persistent energy savings, even after the intervention is removed. • Added intervention by automated calendar controls demonstrated the highest energy savings, after the interventions had been removed. As expected, there is reduced energy awareness, but not reduced persistent energy savings. Beyond its main contribution on energy conservation, awareness and persistent savings, this dissertation contributes to the increasing field study literature on HCI interface choices specifically focused on energy and behavioral impacts. It also adds to the expanding breadth of existing HCI intervention studies in office environments with greater participant numbers over a longer duration; and provides quantified energy savings from technology-specific plug load management in offices through behavioral change.

The challenges are entirely depending on the user adoption of new technology. Other challenges that might delay the progress in government department would be the financial constraints and the socio inequality among our community in the developing countries. Government has a growth in e-government ICT’s infrastructure used in everyday activities and online functionality. These emerge from private entities that the government does business with, to force them to move away from manual function to electronic function and processes. Electronic monitoring system has been there in some parts of the world. Hence the South African government has opt to make use of this tool as it has been have a success results in some parts of the world. Even though there are some challenge the department has decided to implement EM system for monitoring of parolees. This study explores the factors that influence the adoption of electronic monitoring systems of parolees in the Department of Correctional Services (DCS) in South Africa, which will assist the DCS to monitor parolees effectively under budgetary constraints. Also to overcome the challenges of overcrowding, saving more cost of building more new facilities.

Testo completoAbstract (sommario):
Electronic workplace surveillance takes many forms. It includes CCTV, recording telephone conversations, employee ID cards, and electronically gathering and measuring work performance. The increased incidences of electronic surveillance have had a number of effects on employees. This research concentrated on the use of quantified electronic performance measurement. It specifically examined the impact on managers and managing. It examined surveillance from an employment relationship perspective, taking as its primary lens that of exchange and exchange theory. The research demonstrated that the exchange relationships managers have with other managers, workers, or employers, as part of the psychological contract, is being compromised. Managers feel under pressure to manage based on the surfeit of electronic measures rather than by using innate or acquired management skills. Many managers in this research are no longer managers in the conventional sense; instead, they have become “Performance Intermediary Executives” invariably reliant on a plethora of electronic measures provided for them to help them manage successfully. Managers have also started questioning the equitable nature of the psychological contract between them and their employer/line manager. The result of this equity disjuncture was made manifest by the subtle forms of resistance used on a daily basis. Managers are being led down a managerial path leading to further resistance and inequitable employment and exchange relationships. This research suggests that claimed improvements in performance and performance management using electronic surveillance could be wiped out by poor and de-professionalised management. Organisations should be aware that surveillance for surveillance sake is not necessarily always the best way forward. Electronic workplace surveillance is not intrinsically all good or all bad, but judging from the findings in this research, its impact is broadly perceived by managers negatively, which is not good for all parties in the employment relationship.

Zilli, Davide. "Smartphone-powered citizen science for bioacoustic monitoring". Thesis, University of Southampton, 2015. https://eprints.soton.ac.uk/382943/.
Testo completoAbstract (sommario):
Citizen science is the involvement of amateur scientists in research for the purpose of data collection and analysis. This practice, well known to different research domains, has recently received renewed attention through the introduction of new and easy means of communication, namely the internet and the advent of powerful “smart” mobile phones, which facilitate the interaction between scientists and citizens. This is appealing to the field of biodiversity monitoring, where traditional manual surveying methods are slow and time consuming and rely on the expertise of the surveyor. This thesis investigates a participatory bioacoustic approach that engages citizens and their smartphones to map the presence of animal species. In particular, the focus is placed on the detection of the New Forest cicada, a critically endangered insect that emits a high pitched call, difficult to hear for humans but easily detected by their mobile phones. To this end, a novel real time acoustic cicada detector algorithm is proposed, which efficiently extracts three frequency bands through a Goertzel filter, and uses them as features for a hidden Markov model-based classifier. This algorithm has permitted the development of a cross-platform mobile app that enables citizen scientists to submit reports of the presence of the cicada. The effectiveness of this approach was confirmed for both the detection algorithm, which achieves an F1 score of 0.82 for the recognition of three acoustically similar insects in the New Forest; and for the mobile system, which was used to submit over 11,000 reports in the first two seasons of deployment, making it one of the largest citizen science projects of its kind. However the algorithm, though very efficient and easily tuned to different microphones, does not scale effectively to many-species classification. Therefore, an alternative method is also proposed for broader insect recognition, which exploits the strong frequency features and the repeating phrases that often occur in insects songs. To express these, it extracts a set of modulation coefficients from the power spectrum of the call, and represents them compactly by sampling them in the log-frequency space, avoiding any bias towards the scale of the phrase. The algorithm reaches an F1 score of 0.72 for 28 species of UK Orthoptera over a small training set, and an F1 score of 0.92 for the three insects recorded in the New Forest, though with higher computational cost compared to the algorithm tailored to cicada detection. The mobile app, downloaded by over 3,000 users, together with the two algorithms, demonstrate the feasibility of real-time insect recognition on mobile devices and the potential of engaging a large crowd for the monitoring of the natural environment.

Testo completoAbstract (sommario):
Tremendous advances in high performance sensing and signal processing technology enable the development of condition monitoring systems (CMS) for complex engineered systems to detect, diagnose, and predict the system-wide effects of failure events. Although employing CMS in preventing catastrophic system failures and reducing the operation and maintenance (O&M) costs have been acknowledged, the cost and benefit of CMS have not been well studied and further the advantages of CMS have not been fully recognized for the optimal maintenance decision making, mainly due to the lack of valid theoretical modeling addressing the interrelationship between the CMS effectiveness and system downtime due to system failures. In this study, a Poisson Process model will be developed for the modeling of occurrence of the system-wide failure events and study the potential benefits provided by the CMS in preventing these failure events. With the developed Poisson process model, the cost benefit analysis (CBA) will then be implemented by considering the CMS system reliability and costs varying with its failure detection effectiveness presented by the probabilistic detectability measure. Facilitated by CBA of the CMS, break-even points (BEP) between expected lifecycle benefits and the required CMS detectability level can be found to select optimal CMS for different system failure modes. Moreover, with the help of the CBA results, optimal maintenance strategies can be determined to minimize the O&M costs. The presented CBA methodology for the CMS systems will be demonstrated with an aircraft maintenance case study and the efficacy will be validated.Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Industrial and Manufacturing Engineering

Testo completoAbstract (sommario):
The current study investigated whether reactions to electronic monitoring and task satisfaction are a function of the task-relatedness of monitoring practices and the presence of justification for monitoring. A sample of 176 undergraduate participants completed a computer-based task correcting electronic retail order forms. Participants were randomly assigned to one of five conditions: task-specfic monitoring with justification, task-specific monitoring without justification, off-task inclusive monitoring with justification, off-task inclusive monitoring without justification, or no monitoring. Task-specific monitoring involved electronic tracking of computer activities directly related to task performance, whereas off-task inclusive monitoring supposedly tracked nontask-related computer activities. Justification entailed providing a rationale or explanation for why monitoring was being implemented. The following dependent variables were assessed: perceived relevance of monitoring, perceived rationale for monitoring, invasion of privacy, procedural justice, and task satisfaction. Results indicated task-relatedness of monitoring and justification had an effect such that monitoring task-specific behaviors and providing a clear justification for monitoring resulted in relatively favorable attitudinal outcomes. Implications and recommendations for practice are discussed.

Testo completoAbstract (sommario):
Mental health has long been a neglected problem in global healthcare. The social and economic impacts of conditions affecting the mind are still underestimated. However, in recent years it is becoming more apparent that mental disorders are a growing global concern that is not to be trivialised. Considering the rising burden of psychiatric illnesses, there is a necessity of developing novel services and researching effective means of providing interventions to sufferers. Such novel services could include technology-based solutions already used in other healthcare applications but are yet to make their way into standard psychiatric practice. This thesis presents a study on how pervasive technology can be utilised to devise an “early warning” system for patients with bipolar disorder. The system, containing wearable and environmental sensors, would collect behavioural data and use it to inform the user about subtle changes that might indicate an upcoming episode. To test the feasibility of the concept a prototype system was devised, which was followed by trials including four healthy volunteers as well as a bipolar patient. The system included a number of sensory inputs including: accelerometer, light sensors, microphones, GPS tracking and motion detectors. The experiences from the trials led to a conclusion that a large number of sensors may result in incompliance from the users. Therefore, a separate investigation was launched into developing a methodology for detecting behavioural patterns in inputs possible to collect from a mobile phone alone. The premise being that a phone is an everyday use appliance and is likely to be carried and accepted by the patient. The trial revealed that monitoring GPS tracks and Bluetooth encounters has the potential of gaining an insight into a person’s social and behavioural patterns, which usually are strongly influenced by the course of bipolar disorder. Lessons learned during these proceedings amounted to a clearer concept of how a future personalised ambient monitoring system could improve the outcome of treatment of bipolar disorder as well as other psychiatric conditions.

Nicolaou, Nicos. "Electronic performance monitoring : the crossover between self-discipline and emotion management". Thesis, University of Warwick, 2015. http://wrap.warwick.ac.uk/69211/.
Testo completoAbstract (sommario):
This thesis studies the crossover between self-discipline and emotion management in an electronic performance monitoring (EPM) setting. The intersection between these two elements is explained in terms of six main themes: control, power and discipline; compliance, conformity and resistance; rationality, performance standards and corrective action; emotional labour and the management of emotions; society, responsibility and accountability; and subjectivity, internalisation and the self. These main themes emerged from interview data and are supported by the literature. A qualitative methodology was adopted to support a social constructionist perspective. Semi-structured interviews were conducted to collect data from a single case study organisation, and thematic coding was used for analysis. EPM systems installed in the case study call centre are used to control agents’ behaviour, embedding in their minds the importance of controlling and disciplining their own behaviour. They are forced by EPM to manage their own emotions and conform to the rules of the system through self-discipline. Nevertheless, some find it difficult constantly to suppress their emotions and may exhibit resistance. There is a preoccupation with self-correction. Agents internalise the call centre's norms of behavior. The technological environment largely determines the way in which they manage their emotions. They fake their emotions when interacting with callers, supervisors and colleagues, and exercise self-discipline and emotion management to satisfy personal and group expectations. They incorporate the cultural values, motives and beliefs of the EPM context through learning, socialisation and identification. This thesis offers significant theoretical contributions which revolve around the relationship between surveillance-induced self-discipline and emotional labour over time. It aims to alert academics and business people to the problems of emotional labour and to prompt them to make changes to the design, implementation and use of EPM.

Morton, Robert. "Electronic adherence monitoring and reminders in childhood asthma and cystic fibrosis". Thesis, University of Sheffield, 2017. http://etheses.whiterose.ac.uk/19932/.
Testo completoAbstract (sommario):
Sub-optimal adherence to inhaled maintenance therapy is common in children with asthma and Cystic Fibrosis (CF), resulting in poor disease control and increased exacerbations. Electronic monitoring with feedback has been shown to increase adherence in children with asthma by identifying and addressing intentional adherence barriers, and its use is now widespread in CF clinics in the UK. Medication reminders have been shown to be effective at addressing non-intentional adherence barriers in asthma, but have not been investigated in CF. This thesis aimed to investigate electronic monitoring with feedback and reminders to improve adherence and clinical outcomes in children with asthma and CF. Methods 90 children with moderate asthma were recruited to the STAAR study, and randomised to receive an electronic monitoring device (EMD) with 3- monthly feedback of data and alarms, or an EMD without feedback or alarms for a year. The primary outcome was the difference in Asthma Control Questionnaire (ACQ) score, from baseline to 3,6,9 and 12 months. Secondary outcomes were adherence, number of oral steroids required, lung function, hospital admissions, days off school and quality of life. The sample size was calculated using repeated measure analysis, with an MID for the ACQ of 0.5. 17 children were recruited to the Nebtext study and sent reminder text messages for 6 months. The outcomes were difference in overall, weekend and weekday adherence rates before and during the text message period. The sample size was the maximum number of children with CF attending clinic in the recruitment period. Results STAAR The mean [95% CI] difference in ACQ from baseline to 12 months was -1.14 [-1.6 to -0.7] in the intervention group, compared to -0.95 [-1.3 to -0.6] in the control group, with no significant difference between the two (P= 0.51). The mean [95% CI] adherence rate for the intervention group was 71% [63-77], vs. 49% [28-54] in the control group (p = < 0.001). The rate of exacerbations requiring oral steroids in the intervention group was 0.4 per 100 days, compared to 0.7 in the control group (p=0.008). The rate of hospitalisation was 0.03 in the intervention group vs. 0.13 in the control group (p = < 0.01). Nebtext The mean [95% CI] pre-text adherence rate was 80% [65-94], compared to 79% [62-95] during the text period. Conclusion Electronic monitoring with feedback and alarms is effective at reducing exacerbations and hospitalisations in children with asthma. The addition of reminder texts to existing electronic monitoring in children with CF does not further improve high baseline adherence rates.

Testo completoAbstract (sommario):
The use of electronic monitoring (EM) as a tool to supervise high-risk offenders has increased in the field of criminal justice in the state of Texas. Although EM is now widely used to supervise high-risk offenders to prevent them from committing further crimes, it is unclear whether EM has achieved the purpose of reducing reoffenses during parole supervision. Hirschi's social bond theory, which was later developed into social control theory, was used as the framework for this general qualitative study to explore retired parole officers' perceptions concerning whether EM is successful in preventing high-risk offenders from committing additional crimes. Interview data were collected from 10 retired parole officers who supervised high-risk offenders on EM in Harris County, Texas. The findings revealed that the 10 officers perceived EM to be an effective tool, but they perceived the role of capitalizing on positive social bonds was equally important in controlling criminal behavior. Specifically, the officers perceived that their bond with the high-risk offenders on EM could diminish offenders' propensity to commit new crimes. Opportunities for positive social change stemming from this study include recommendations to the Texas Department of Criminal Justice to develop policies and training that is consistent with social bond theory, and retrain parole officers to emphasize to offenders positive contacts and relationship with family and continuing employment during the term of parole release in order to reduct opportunities for reoffense and futher victimization to the community.

Testo completoAbstract (sommario):
In recent years, harsher sentences have been pursued in criminal offenses leading to an increase in the use of incarceration. Prisons, largely unable to keep up with this demand, have become overcrowded in most areas. In response to prison overcrowding, some jurisdictions have begun to experiment with electronically monitored house arrest.
This thesis is composed of a literature review and proposed study of recidivism in electronic monitoring (EM) programs. The literature review is composed of a general review of the history of corrections, a review of literature on electronic monitoring programs and social bond theory.
The history of corrections serves to partially explain the emergence of electronic monitoring programs as an outcome of the adoption and failure of other forms of intermediate sanctions. The present state of electronic monitoring, including a description of the technology incorporated in these programs, the extent to which EM programs are implemented, and their cost effectiveness are discussed. In addition, some legal implications of its use are discussed.
A review of previous research indicates numerous gaps in the existing evaluation of electronic monitoring programs. Because of these gaps many research questions are not sufficiently answered by the literature review. The rate of recidivism for EM programs compared to that of other correctional programs remains unclear. The underlying factors that affect the recidivism rate for EM programs also remains unclear. In addition, the effects on the offender, the offender’s family, peer group, and employment are not identified. The two reasons responsible for the inability of previous studies to adequately assess the rate of recidivism for EM programs compared to standard probation of parole and the underlying factors predicting recidivism are the exclusion of variables pertaining to the effects of electronic monitoring on the offender as well as the lack of theory needed to understand the relationships of recidivism, and type or correctional program.
Literature on social bond theory is reviewed in order to provide theory to the examination of recidivism in electronic monitoring programs. Beginning with an explanation of Hirschi’s original work (1969), the review extends to empirical literature on the social bond. Finding this literature to be strongly supportive of social bond theory, it is adopted as a structure to examine recidivism. Primarily used in the study of delinquency, social bond theory is adapted to apply to the study of adult populations and recidivism, and the possible effects of EM on the social bond is discussed.
A proposed research study is then presented examining the effects of EM on social bond factors and subsequently recidivism. The relevance of control variables, including length of sentence, type of offense, and prior convictions are discussed as well as the measurement of variables related to social bond theory. A structural equation model is developed that incorporates the control variables, bond variables, program variables, and recidivism, allowing for a simultaneous estimation of their relationships, using LISREL 8. It is hypothesized that EM programs, more than standard probation and parole positively affect the social bond of an offender to his or her family, peer group, and employment. In addition, it is believed that a stronger social bond to the institutions of family, peer group, and employment results in a lower incidence of recidivism.Master of Science

Testo completoAbstract (sommario):
Sensors are playing an increasingly important role in our lives, and for these devices to perform to their maximum potential, they need to work together. A single device can provide a single service or a fixed set of services but, when combined with other sensors, different classes of applications become implementable. The vital criterion for this to happen is the ability to bring information from all sensors together, so that all measured physical phenomena can contribute to the solution. Mediation between applications and physical sensors is the responsibility of sensor network middleware (SNM). Rapid growth in the kinds of sensors and applications for sensors/sensor systems, and the consequent importance of sensor network middleware has raised the need to relatively rapidly build engineering applications from those components. A number of SNM exist, each of which attempts to solve the sensor integration problem in a different way. These solutions, based on their ‘closeness’ either to sensors or to applications, can be classified as low-level and high-level. Low-level SNM tends not to focus on making application development easy, while high-level SNM tends to be ‘locked-in’ to a particular set of sensors. We propose a SNM suitable for the task of activity monitoring founded on rules and events, integrated through a semantic event model. The proposed solution is intended to be open at the bottom – to new sensor types; and open at the top – to new applications/user requirements. We show evidence for the effectiveness of this approach in the context of two pilot studies in rehabilitation monitoring – in both hospital and home environment. Moreover, we demonstrate how the semantic event model and rule-based approach promotes verifiability and the ability to validate the system with domain experts.

Wang, Minlue. "Monitoring plan execution in partially observable stochastic worlds". Thesis, University of Birmingham, 2014. http://etheses.bham.ac.uk//id/eprint/4898/.
Testo completoAbstract (sommario):
This thesis presents two novel algorithms for monitoring plan execution in stochastic partially observable environments. The problems can be formulated as partially-observable Markov decision processes (POMDPs). Exact solutions of POMDP problems are difficult to find due to the computational complexity, so many approximate solutions are proposed instead. These POMDP solvers tend to generate an approximate policy at planning time and execute the policy without any change at run time. Our approaches will monitor the execution of the initial approximate policy and perform plan modification procedure to improve the policy’s quality at run time. This thesis considers two approximate POMDP solvers. One is a translation-based POMDP solver which converts a subclass of POMDP, called quasi-deterministic POMDP (QDET-POMDP) problems into classical planning problems or Markov decision processes (MDPs). The resulting approximate solution is either a contingency plan or an MDP policy that requires full observability of the world at run time. The other is a point-based POMDP solver which generates an approximate policy by utilizing sampling techniques. Study of the algorithms in simulation has shown that our execution monitoring approaches can improve the approximate POMDP solvers overall performance in terms of plan quality, plan generation time and plan execution time.

Testo completoAbstract (sommario):
This research thesis is about developing an electronic-learning readiness (e-readiness)
model for the training of employees in distance education. The overall purpose of the
model is to improve current computer-facilitated educational practices in the workplace
by enabling e-Iearning practitioners to plan better for the e-Iearning event.
There are various definitions of e-readiness, like the ones mentioned by Budhiraja and
Sachdeva (2005:4) and the APEC Readiness Initiative (2005:1), most of which refer to
readiness in the larger sense, namely of countries' readiness for electronic media use.
The context in which the concept of e-readiness is used in this research is similar to the
definition cited by Online Reporting Specialists (2005), namely "The state or quality of
being ready for electronic learning such as the internet." The context in which it is used
is geographically smaller and in line with Hill and Raven's (2000) description, namely it
is not limited to physical readiness alone but also includes the non-physical readiness of
a business or organisation, e.g. mental readiness as well as organisational cultural
readiness.
The literature research explores the inherent characteristics of distance education,
Constructivist learning and the use of electronic media for distance education. From the
literature research, generic aspects that can influence the readiness for electronic
learning in distance education in a workplace are identified and integrated into an initial
workplace e-readiness concept model.
The concepts underlying the newly constructed e-readiness model are verified through
a quantitative research process, changed according to the findings and further refined.
An e-readiness audit model (evidence required for compliance) is designed through a
qualitative research process. The final model is tested in the workplace by using a
combined qualitative and quantitative research process and the results reported. In
conclusion a workable e-readiness model has been developed to be used as point of
departure for any vocational educationist when planning, diagnosing problems of or
evaluating an e-Iearning event.
Important recommendations as regards further research are made in respect of the
application of the model to relevant fields of study:
- A South African e-Iearning specialist group should be considered to determine the
e-readiness requirements and particularly to focus on e-Iearning habits and needs
in the South African context.
- Further research needs to be done to determine which requirements are
appropriate to the various e-Iearning delivery systems.
- Further research can determine if any criterion of the e-readiness model is more
important than others.
- The study needs to be extended to other more diverse workplaces.
- More research needs to be done to determine the needs and requirements of e-readiness
of each unique group as an entity within a larger diverse group.
- Further research should consider language barriers by translating questionnaires
into the respondents' home language.
- Explanation of computer terminology before the questionnaire is completed is
advisable as not all respondents may be familiar with the concepts.
- Further refinement of the audit instrument as well as questionnaires can be done
through further research.Thesis (Ph.D. (Education))--North-West University, Potchefstroom Campus, 2007.
