Field, Oliver Hugh. "Risk factors for arson recidivism in adult offenders." Thesis, University of Birmingham, 2016. http://etheses.bham.ac.uk//id/eprint/6639/.
Full textAbstract:
This thesis explores risk factors for recidivistic arson in adult offenders. Chapter one provides an introduction to the characteristics of adult firesetters and theoretical approaches to understanding their behaviour. Chapter two provides a critique of the Fire Setting Scale (FSS) in terms of its psychometric properties and concludes that the FSS shows promise as a psychometric measure of fire interest and antisociality associated with firesetting in the general population. Chapter three contains a systematic review of the evidence base relating to risk factors for recidivistic arson in adult offenders. Standardised effect sizes are calculated and the data synthesised to identify risk factors with varying strengths of empirical support. The 15 studies reviewed varied in quality, contained few female subjects, and often studied psychiatric rather than wider criminal justice populations. The empirical research presented in Chapter four consists of a retrospective case-control study comparing a large sample of recidivist and first-time arsonists on a range of variables. Separate analyses for female and male subjects revealed differences in risk factors. Logistic regression was used to build predictive models of arson recidivism which were then operationalised into gender-specific risk prediction tools. Theoretical and clinical implications of the thesis are discussed in Chapter five, and a preliminary model of arson recidivism is proposed.

Questa tesi si occupa di analizzare il sistema dell’arte contemporanea francese soffermandosi sui Centri nazionali d’arte contemporanea francesi (CNAC) e in particolar modo tratta il caso specifico del Centre national d’art contemporain, Villa Arson di Nizza.
Partendo dunque dallo studio del processo di sviluppo del sistema dell’arte contemporanea francese, la tesi individua le tappe attraverso le quali lo stato sia arrivato a creare questi CNAC. Nello specifico, il primo capitolo si concentra sulla nascita dei Salon ufficiali, sui mutamenti avvenuti nel mercato dell’arte nel corso del Novecento, fino ad arrivare alla creazione dei primi musei d’arte contemporanea in Europa.
Il secondo capitolo si occupa di determinare le differenti politiche culturali francesi attuate, tra gli anni ’60 ed ’80, che hanno permesso la creazione dei centri nazionali d’arte contemporanea ed inoltre gli organismi gestionali statali che garantiscono il sostegno ai CNAC.
Nella trattazione del caso studio di Villa Arson viene delineato sia l’aspetto socio-politico della sua trasformazione in centro, sia quello storico-artistico legato alla scena artistica in Costa Azzurra, anche attraverso l’analisi di alcuni casi di studio legati alle esposizioni passate.
Nel capitolo conclusivo ci si sofferma sugli aspetti di management analizzando l’offerta didattica e formativa di Villa Arson tentando un confronto tra la tipologia dei CNAC e le strutture di musei contemporanei italiani o internazionali.

Kappel, C. "An environmental and behavioural analysis of arson in a Danish sample." Thesis, University of Liverpool, 2018. http://livrepository.liverpool.ac.uk/3023901/.
Full textAbstract:
Background: Despite its significance as a costly and destructive criminal behaviour, there appears to be some consensus that we know relatively little about arson compared to many other areas of criminal behaviour. Moreover, most existing theory and research into arson has come from the USA, and has tended to concentrate on profiling the characteristics of offenders, rather than investigating, at least in any detail, features of the environment that may influence their behaviour. Aim: The main aim and overarching theme of the current thesis was, therefore, to describe and evaluate some of the main demographic and biographical characteristics, offence related behaviours, and environmental factors associated with arson, in a sample of arson offenders from a European country. Methods: Six empirical studies were conducted, each based on cases drawn from a sample of 746 cases committed by 540 offenders from Denmark between 2002 and 2010 in two police districts, one rural and one urban. Studies 1 and 2 examined a range of demographic and biographical characteristics of arson offenders (such as, gender and age); Studies 3 and 4 covered offence related behaviours (such as selection of targets, and travel distances), and employed regression analyses to look specifically at how these were predicted by other offence related and demographic and biographical variables. Study 5 then investigated the prediction of serial offending as an indicator of arson recidivism using the above demographic and biographical variables and offence related variables. Finally, Study 6 attempted to employ a new approach, via Google Earth, to examine the influence of a range of architectural and structural features of the environment on arson offending; these included 2 targets, presence of high rise buildings, territorial markers, population density and maintenance. Results and Discussion: Findings supported previous literature in identifying the typical arsonist as a young male offender; however, the results further suggested three possible divergent trends in the data corresponding to different categories of arson offender: 1) a more frequent opportunistic arsonist; 2) a less frequent, but more serious, often more persistent serial offender, and 3) a category of mainly female offenders who are less likely to be serial offenders but who may be reacting to dysfunctional home environments. Importantly, in relation to the latter finding, a bimodal peak in age emerged in the subgroup of female offenders, identifying a younger group of female offenders in their mid and late teen years and an older subgroup of female offenders in their late thirties and early forties. Another notable finding was that young male offenders who were not at school were particularly at risk for becoming serial offenders, suggesting that young males not attending school could be targeted in terms of prevention of persistent arson. Also, as predictors of arson, a number of environmental variables were significant and in line with predictions (for example, arson was more prevalant where there were vacant buildings, and very significantly, where the nearest police station was farthest away), but others were significant in a direction opposite to predictions (high building density was associated with lower rates of arson), and some potentially important predicted relationships failed to emerge as significant predictors (such as territorial markers). In addition to the above, two other major findings emerged. First, whilst it was possible be to predict crime scene behaviours from other crime scene behaviours with some degree of accuracy, and, similarly, demographic behaviours (like previous arson) from other demographic factors, predicting crime scene behaviours from demographic factors and vice versa proved to be considerably more difficult. In contrast, in terms of having 3 maximum impact on arson rates the environmental variables considered here did a relatively good job of predicting the presence of arson. A number of limitations and implications are also discussed. Conclusion Considering the results as a whole, notwithstanding some success in predicting arson from demographic and offence related variables, it is concluded that an extension of the kind of environmental approach explored in this thesis could potentially be used for developing environmental schemes for arson prevention that might be considerably easier to apply, and perhaps even more effective in reducing arson, than targeting 'at risk' groups of individuals.

Full textAbstract:
The influences that crime control, due process factors, and individual demographic characteristics have on the criminal trial outcomes of accused arsonists was unknown. Absent this knowledge, it was not clear if public policy ensures justice for the accused, particularly for the disadvantaged. The purpose of this quasi-experimental study was to investigate, using Packer's due process and crime control model as the theoretical framework, the relationship between time to trial, number of defense and prosecution witnesses, access to fire origin and cause experts, legal representation type, age, race, education, and gender and criminal arson case outcomes. A sample size of 165 archival court records of those accused of arson from 2011-2015 were analyzed using Packer. According to the results of the logistic regression models, there was a significant relationship (p < .05) between trial outcomes and the use of fact witnesses by the defense and by the prosecution.This relationship moved the pendulum toward crime control for the selected population. The ordered logistic model explained 6.9% of the variation in the criminal case outcomes. Policymakers can use the results of this study to inform criminal justice policy and to prioritize funding to assure fairness and social justice for the accused. Arson defendants and their counsel can use the results to prepare their defense to assure their social justice while prosecutors can use the results to better inform their decisions to assure the legal and factual guilt of the defendant. Future research is needed to provide a clearer understanding of the role that other variables play in the outcome for the population.

Full textAbstract:
Opportunity theories of crime suggest that crime occurs in specific spatio-temporal patterns due to an increase in opportunity and a decrease in risk. Financially-motivated crimes have been demonstrated to be influenced by the economy. From an opportunity perspective this is likely to be due to changes in an individual’s financial circumstances leading them to view the benefits of crime to outweigh the risks. To extend this idea, this research is examining whether financial hardship influences the perceived costs/benefits associated with crimes such as vehicle arson committed with the intention of escaping debt. From 1997-2003, vehicle fires in Surrey were occurring at a rate more than double the national average and many of these were transpiring under suspicious circumstances. Using an opportunity theory framework, this study aims to examine the spatio-temporal patterns of vehicle arson and discover how it was effected by changes in economic conditions. The data for this study were obtained from Surrey Fire Services and contain information on all fires that involved a vehicle in Surrey from 2000-2015. The vehicle fire data were separated into arson and non-arson groups depending on their recorded act/omission and various economic variables were considered to represent the market. Vehicle arson trends were examined over the study period along with motor vehicle theft data, economic variables and the non-arson fire data. Relative to the unsuspicious vehicle fires, vehicle arson was significantly more likely to occur at night in areas with little surveillance. Results indicate that vehicle arson increases during times of economic downturn. Vehicle arson significantly increased following a rise in unemployment and interest rates whilst non-arson vehicle fires remained stable throughout the study period thus supporting an opportunity theory of crime. Results are discussed with relation to situational crime prevention policy and practice.

Full textAbstract:
This thesis examines the effects of age, time period, and cohort on arrest rates for two specific offenses: larceny-theft and arson. The required longitudinal data were gathered from the Uniform Crime Reports from 1965 through 1984.
The analytical procedures used in this study include the dummy variable conversion of the correlation and the multiple regression. We found that the more frequently one is arrested for larceny-theft and arson, the more likely one will be arrested for other offenses. This was more the case for arson than for larceny-theft. The inverse relationship between age and arrest rates for larceny-theft and arson combined show younger persons (15-34) were more prone to be arrested than older ones (35-64). These findings are in agreement with those found in other studies.
The regression analysis supported hypotheses 1 and 3, i.e., age and cohort had a signficiant impact on the arrest rates for both larceny-theft and arson. Hypothesis 2 was not confirmed, i.e., time period did not have a signficiant effect on arrest rates for larceny-theft or arson.

Full textAbstract:
Firesetting has significant social and financial consequences. Firesetters are deemed a dangerous group with a poor prognosis. The existing literature has focused on describing the characteristics of firesetters and developing typologies. The psychological understanding of firesetting is limited. Implicit theories are underlying causal theories. Positioned within a social cognitive framework they are thought to be the intervening process between observable stimuli and responses which enable individuals to make sense of their social world and make predictions within it. The identification of implicit theories has contributed to the understanding of the way information processing is carried out by other offender groups. This study aimed to explore the implicit theories held by male firesetters in secure forensic psychiatric services. Using grounded theory methodology, interviews were conducted with nine men with a history of firesetting. Six implicit theories were generated: malevolent world, uncontrollable world, violence is normal, accountability, fire is controllable and fire is a powerful tool. These implicit theories have the potential to be utilised as treatment targets by challenging and restructuring them. Future research should focus on exploring the specific implicit theories at different points in the offense process, those held by subtypes of firesetters, and those held by female firesetters.

Full textAbstract:
CHDS State/LocalAlthough perhaps not so dramatic or newsworthy as chemical, biologic, radiologic, nuclear, or explosive attacks, intentionally set fires are identified security threats to federal buildings accessible to the public. The Department of Homeland Security Interagency Security Committee in 2010 adopted building construction standards that purport to give facility safety committees and building designers guidance on developing permanent countermeasures to 31 diverse threat scenarios described in the Design-Basis Threat. To assess the effectiveness of the permanent countermeasures options provided in the Physical Security Criteria for Federal Facilities, a performance-based approach to evaluating the design and construction features is recommended. Clearly articulated performance objectives and quantifiable characterization of the hazardous elements comprising the threat scenarios are essential to evaluating outcomes using a performance-based design approach. A mixed methods research approach is used to analyze the Physical Security Criteria for Federal Facilities standard to make policy recommendations that may enhance occupant safety and federal property protection from arson attacks. Computerized fire effects modeling is used to compare outcomes in non-military and non-postal federal facilities from a variety of simulated arson scenarios using commonly available accelerants.

Full textAbstract:
One of the lowest prosecuted crimes in western civilisation is arson. Defence ‘experts’ may be able to discredit a prosecution charge by demonstrating that there are alternative causes for the fire that their defendant was being accused of setting, which were not investigated thoroughly, nor disproved. Unlike many other crimes, a fire may not be detected as arson until the final stages of an investigation, whereas with most other crimes, there is an obvious victim of a crime in the early stages of an investigation. The investigation of fires can be extremely complex. Fire investigators need to ensure that they have conducted their investigation using a systematic and rigorous methodology so that their findings can with-stand any challenges. At the beginning of this project, it was identified that there was a fundamental lack of a systematic methodology to investigate the cause of fires and a need for one to be developed. To address this need, a series of 23 Fire Investigation Road Maps (FIRMs) have been designed, developed and tested at real fire scenes and also during cold case fire investigation reviews to assist a competent fire investigator conduct a thorough, rigorous and systematic investigation to determine the origin and cause of a fire. It is the cause of the fire, that being the ignition source, first combustible material to become ignited and the mechanism that brought the two together which will determine whether the fire was started accidentally or deliberately. The FIRMs are based on the application of the Scientific Method and are divided into groups and categories to ensure a rigorous and thorough process is carried out during an investigation. Some examples of applications of the FIRMs during fire investigations when working with the police, forensic scientists and insurance investigators are the Bethnal Green Road two fire fighter fatalities; ‘Operation Refit’, reviewing the murder of Wayne Trotter; the Iron Mountain data storage depot in East London and the fire in the high rise flats, Lakanal, where six occupants lost their lives. The outcomes of these examples, and many other fire investigations, when applying the FIRMs have demonstrated to the relevant authorities, including several Coroners, that a complete and accurate fire investigation has been conducted. Utilising the FIRMs during a fire investigation will benefit society by enabling existing data to be gathered, documented, analysed and made available for many interested parties, such as Coroners, civil and criminal prosecutors or used to identify any fire safety issues which need addressing. The accurate identification of the cause of a fire, with supporting forensic evidence, will assist the courts in making decisions as to whether the fire was accidental, deliberate or the result of a design or system failure. In the circumstances of deliberate fires, the FIRMs will support any subsequent prosecutions and help increase the low arson prosecution rates that currently exist.

Full textAbstract:
Deliberately lit fires make up over 15% of all fires in New Zealand buildings yet they are
typically omitted from the design brief for fire engineering purposes. This report examines
where deliberately lit fires should be included as part of the fire engineering design by
examination of all deliberately lit fires recorded in the New Zealand Fire Incident
Reporting System (NZ FIRS) between the years 1996 and 2006.
The main types of buildings identified where consideration of deliberately lit fires within
the design would provide benefits are:
· Prisons
· Psychiatric institutions
· Schools
· Crowd activities
· Attached accommodation
The report also examined what is required to include deliberately lit fires as part of the
design process. Based on an analysis of the fire incident statistics, the majority of
deliberately lit fires are the result of unplanned activities and existing design fires will be
adequate. Two critical fire scenarios were identified as exceeding these requirements, the
ignition of multiple fires and the use of accelerants. Greater life safety benefits are obtained
by considering accelerants.
In the case of multiple fires, each fire is likely to be within the capabilities of a fire
engineered building however a number of such fires may overwhelm the fire protection
features of a building. A number of issues for the fire engineer to consider are briefly
discussed. In the case of accelerants, a number of experiments were completed to
characterise the heat release rate and species production of a Molotov cocktail based on the
fuel volume used. A second round of experiments extended this work by examining the
scenario where a Molotov cocktail containing 1000 milliliters of petrol was deployed
within a stairwell.

Full textAbstract:
This study investigated the antecedents and psychological processes inherent in firesetting within an adult intellectually disabled population. A qualitative methodology, grounded theory (GT) was employed to explore the experience of firesetting through verbal self-report. A sample of eight males with mild intellectual disabilities under the care of forensic learning disability services participated in interviews which ranged from 27 minutes 14 seconds to 1 hour 21 minutes 22 seconds. The data produced a preliminary GT which identified eight conceptual categories: Managing internal affect states, the experience of adversity, unsafe others, engagement in multiple offending behaviours, voice entitlement, experiences of fire, and mediators of risk and the function of firesetting. These conceptual categories were linked by an overarching core category of ‘powerlessness’ which was evident in several areas of the participants’ lives and experiences of firesetting. It was concluded that this sense of powerlessness along with the conceptual categories should be considered when risk assessing, delivering firesetting specific treatment and psychological interventions. The clinical implications are discussed and suggestions are made for replication of the current study with larger, more diverse samples and future directions for further research are proposed.

Full textAbstract:
This thesis falls within the category of historical studies that is concerned with a difficult legacy of South AfricaÌs liberation struggle, namely the practice of necklacing that accompanied it. My interest in the practice is limited to its emergence and politicising as it relates to the ANC, the UDF and the apartheid state. The ANC and the UDF overwhelmingly understood the practice as resistance, yet ambivalently so. The question guiding this thesis therefore asks: how is necklacing written into the narrative of struggle history? Here I refer to its (re)representation, its (re)characterisation, its (re)articulation in a wider discursive war of propaganda strategies that was waged through the interplay of an apartheid state discourse and what I consider to be an official non-state discourse, that of the ANC and the UDF.

This project involved an evaluation of firefighter involvement in Youth Justice Conferencing to determine whether, and if so how, this program facilitates the prevention of youth misuse of fire. Evaluation comprised quantitative analyses of a decade of Youth Justice Conferencing records and recidivism data, alongside qualitative analysis of program practitioner interviews. Findings revealed that, although there are some areas in need of improvement, Youth Justice Conferencing with firefighter involvement contributes to a reduction in the risk of general recidivism, whilst providing an avenue through which to deliver fire safety education to at-risk groups within the community.

Master’s thesis deals with a determination problem of ignitable liquids from fire debris. The aim of this work is to introduce the properties of used fire accelerants and to give an overview and evaluation of the various techniques which can be conducive to the fire investigator. Determination of fire accelerants from fire debris was made by the technique of solid phase microextraction (SPME) with subsequent chemical analysis by GC/MS. Based on the chromatographic results were established the target compounds and reconstructed ion chromatograms which are typical for some kinds of flammable liquids. There were used gasoline, diesel, kerosene and technical gasoline (white spirit) as the fire accelerants. This work also deals with the influence of interfering products in fire debris analysis, including their identification and characterization. Different kinds of substrates were burned, extracted and analyzed in order to identify all the interfering products that they may release.

Syftet med denna uppsats är att utifrån ett uppdrag från Christina Innala vid Örebropolisen undersöka huruvida det går att utläsa beteendemönster hos svenska mordbrännare som kan ligga till grund för vidare geografiska analyser. I uppsatsen kommer vi att se närmre på mordbrännare och geografisk profilering utifrån svenska förhållanden. Materialet som ligger till grund för uppsatsen består av domslut gällande mordbränder och dessa analyseras och kategoriseras. De domslut som i materialet har omfattat seriemordbrännare har analyserats utifrån geografisk profilering med hjälp av mjukvaran GeoProfile. Detta för att undersöka hur brottplatser förhåller sig till fasta punkter för svenska seriemordbrännare.Sammanfattningsvis kan man utifrån vårt material identifiera sex stycken kategorier av mordbrännare. Dessa kategorier stämmer överrens med tidigare forskning. Utifrån våra geografiska profileringar kan man dra slutsatsen att seriemordbrännare tenderar att anlägga sina bränder i anslutning till en eller flera fasta punkter. Den svenska mordbrännaren är alltså inte en irrationell individ som slumpmässigt och oberäkneligt anlägger bränder. Bränderna tenderar ofta att uppstå inom en gärningsmans rutinaktivitetsområde, det vill säga att gärningsmannen vanligtvis begår brott i områden som denne känner till.As an a assignment from Christina Innala at the police in Örebro, this paper aims to investigate whether it is possible to discern behavioral patterns of Swedish arsonists as a point of departure for further spatial analysis. In this paper geographic profiling based on Swedish conditions will be studied. The material that is the basis for the essay consists of judicial decisions regarding arson and these will be analyzed and categorized. The judicial decisions that in the material has included serial arsonists has been analyzed based on geographic profiling using the software GeoProfile. We want to examine wheatear crime scenes are related to anchor-points for Swedish serial arsonists.In summary, based on our material we were able to identify six categories of arsonists. These categories match those of previous research. Based on our geographic profiling it can be concluded that the serial arsonists tend to set their fires in connection with one or more anchor-points. The Swedish arsonist is not an irrational individual that randomly and unpredictably set fires. Fires tend to occur within a criminals routine activity area, in other words the offender usually commits the offense in areas that is known for him/her.

Full textAbstract:
The source of potassium and argon in ordinary chondrites is determined by comparing the argon activation energies of feldspar, pyroxene, and olivine with that of the L chondrites Chico and North West Africa (NWA) 091. In addition, shock pressures of 29 to 55.8 GPa are shown to lower the activation energy of feldspar. Comparable shock pressures lowers the activation energy of pyroxene outside of error, but the variability of this value, even among unshocked samples, makes a clear distinction difficult. The effect of shock on olivine has not been investigated, by myself or others. Like many ordinary chondrites, Chico and NWA 091 have two major releases of argon, one at low temperature, and the other at high temperature. The low temperature release of Chico contains two releases, which match the activation energies of shocked and unshocked feldspar. The low temperature release of NWA 091 only contains a single release, which matches shocked feldspar. The high temperature release of both Chico and NWA 091 has an activation energy that is similar to pyroxene, but not olivine. A potassium mass balance of Chico shows that all the potassium in the meteorite is contained in feldspar, and Raman spectroscopy shows this feldspar has not been converted into a high pressure phase, indicating the high temperature release is inclusions in a high temperature mineral. This mineral is probably pyroxene based upon the activation energy, though thin sections provide evidence that feldspar is more closely associated with olivine. NWA 091 exhibits multiple isochrons, showing the presence of two nonprimordial and (probably) non-terrestrial trapped components of argon. The removal of these trapped components reveals a thermal event produced by a collisional impact on the L chondrite parent body at 475 ± 6 Ma (which supports a link between L chondrites and Ordovician fossil meteorites), as well as a similar event at ~800 Ma (which, combined with similar ages on other Solar System objects, suggests an increased impact flux at that time). Chico did not exhibit an isochron, and the age data for Chico is not reported.

The aim of this thesis has been to develop a proposition for a new type of snail barrier, whose function is not based on the use of toxic chemicals or electric current. We have mainly used Fredy Olsson´s methods described in the compendium "Princip- och primärkonstruktion" After a thorough review of previous research and the accompanying definition of criteria, we sketched out six different propositions. By weighting the criteria in a Kesselring matrix, we selected one of the proposals for further development. The main criteria we had to take into account were; the weight of the product, the ability to recycle the material, the price and that it would be modular. The work has resulted in the development of a product that meets all the criteria, and is ready for manufacturing, though field conditions tests that can confirm the effectiveness remains to be done.

Full textAbstract:
This thesis describes the dipole trapping of both metastable and ground state argon atoms. Metastable argon atoms are first Doppler-cooled down to ∼80 μK in a magneto- optical trap (MOT) on the 4s[3/2]2 to 4p[5/2]3 transitions. These were loaded into dipole traps formed both within the focus of a high-power CO2 laser beam and within an optical build-up cavity. The optical cavity’s well depth could be rapidly modulated: allowing efficient loading of the trap, characterisation of trapped atom temperature, and reduction of intensity noise. Collisional properties of the trapped metastable atoms were studied within the cavity and the Penning and associative losses from the trap calculated. Ground state noble gas atoms were also trapped for the first time. This was achieved by optically quenching metastable atoms to the ground state and then trapping the atoms in the cavity field. Although the ground state atoms could not be directly probed, we detected them by observing the additional collisional loss from co-trapped metastable argon atoms. This trap loss was used to determine an ultra-cold elastic cross section between the ground and metastable states. Using a type of parametric loss spectroscopy we also determined the polarisability of metastable argon at the trapping wavelength of 1064 nm.

The main goal of this thesis is creating diagnostic software for analyse communication via protocol ARION. That software would record and store communication data which can be analyzed late and also allows direct communication analysis in real time. Except that there will be visualization functions, for effective representation of data (stored or real-time recorded). This software can be used either by net developers or by end-users like easy visualization software. Next point is describing communication protocol ARION and create developer’s handbook. The practical part of this thesis consists of two points. The first one is developing simple device which allows communicating via protocol ARION. In second communication firmware for that device is written and tested.

The amorphous carbon films were deposited on silicon-metal substrates by plasma jet chemical vapor

atmospheric pressure in Ar/ C2H2 and Ar/H2/C2H2 mixtures. The films prepared in Ar/C2H2 plasma are attributed
to graphite-like carbon films. Addition of the hydrogen decreases growth rate and the surface
roughness of the coatings, but coatings have low fraction of oxygen (~5 at.%) The formation of the nanocrystalline

Untersucht wurde der Arsen- und Cadmiumtransfer vom Boden in die Pflanze. Die Boden- und Kornproben entstammten den Dauertestflächen aller Bodenregionen in Sachsen. Um die Pflanzenverfügbarkeit der beiden Elemente zu untersuchen, wurden sieben verschiedene Extraktionsmethoden verglichen. Der Aufschluss mit Königswasser oder Calcium-Ammonium-Lactat (CAL) zeigt dabei die höchsten Konzentrationen im Extrakt. Die Einhaltung des aktuellen Cadmium-Höchstgehalts für Brotweizen ist bis zu einem Cadmium-Gehalt des Bodens (Königswasser) von 1,0 mg/kg mit einer Wahrscheinlichkeit von 80 % gegeben. Auf der Grundlage der CAL-Extraktion beträgt dieser Schwellenwert 0,4 mg/kg. Die erwartete Absenkung des zulässigen Höchstgehalts auf 0,10 mg/kg Korn verschiebt die Schwellenwerte auf 0,40 mg CdKW/kg bzw. 0,22 mg CdCAL/kg.
Die Untersuchungen im Freiland bestätigen die sortenspezifische Aufnahme von Cadmium aus Gefäßversuchen. Für die Transferuntersuchungen wird eine mehrfache Beprobung eines Schlages empfohlen, wobei jeweils von einem ca. 4 m² großen Teilstück eine Bodenmischprobe und eine Mischprobe des zugehörigen pflanzlichen Materials entnommen werden sollte.

Full textAbstract:
The advancement in laser technology in the past few decades have enabled consistent generation of pulses in the femtosecond (fs, x10^-15 s) timescale. The strong electric fields produced by such pulses are comparable to those experienced by bound electrons within atoms and molecules, leading to highly non-linear interactions. One of the most probable such interaction is that of strong-field excitation where the target is left in an excited state. These excited states have been shown to influence other strong-field phenomena and exhibit unique properties that are useful for further applications such as, generation of coherent extreme-ultraviolet radiation, and lasercooling of noble gases. Therefore, a comprehensive understanding of the fundamental excitation process and how excitation rates are affected is necessary in order to tailor conditions for a desired outcome. So far, there have been only a few experimental studies on excitation yields due to the unique experimental arrangements required for observation of these states. In contrast, there have been more theoretical studies which have yet to be experimentally confirmed. The aforementioned experiments have been undertaken with laser pulses with a duration of 30 fs or more centred at a wavelength of 800 nm which contain many optical cycles. But, numerical calculations predict that excitation yields scale differently as the pulse duration reduces such that it contains only a few optical cycles. This has yet to be experimentally confirmed since there has not been any experimental studies on excitation yields from few-cycle pulses. Furthermore, the use of few-cycle pulses enables precise control over the electric field experienced by the atom which may influence the excitation process.
In this dissertation, we experimentally investigate excitation yields of argon interacting with multi- and few-cycle pulses centred at 800 nm and compare them to solutions of the time-dependent Schrodinger equation (TDSE). The first investigation explores the effect of changing the intensity spanning between 50-300 TW/cm2. By directly detecting excited states surviving the flight time to the particle detector, we show that excitation rates exhibit a step-wise increase within the intensity range which correspond to the absorption of 13 and 14 photons with linearly polarized multi-cycle pulses. These were predicted theoretically but were thought to be washed out due to volume-averaging inevitable in the experiment. Analysis of the numerical predictions reveal that these enhancements are mainly due to excitation into low-lying states, specifically the 5g and 6h states for 13- and 14-photon absorption, respectively. These increases are not observed with few-cycle pulses where the offset between the peak of the pulse envelope and the peak of the central electric field cycle, known as the carrier-envelope phase (CEP), was not locked. This is in excellent agreement with TDSE predictions. Population of low-lying states are largely preferred with few-cycle pulses and these enhancements are less pronounced, to the point where they do not persist after volume-averaging.
The second investigation explores excitation with elliptically polarized laser fields of varying ellipticities at select intensities with both multi- and few-cycle pulses. In all cases, excitation rates decrease quicker with increasing ellipticity than that of Ar+ but slower than predicted with the strong-field approximation as well as Ar2+. This indicates a different mechanism than the tunneling-plus-rescattering model proposed for the formation of Ar2+ through non-sequential double ionization. No anomalous peaks at non-zero ellipticity are observed in the experiment for 30 fs and 6 fs pulses at an intensity of 270 TW/cm2 and 200 TW/cm2, respectively, nor were they predicted by TDSE results. At a lower intensity, where previously published results from semi-classical modeling predict anomalous distributions, no obvious deviations from a normal distribution is observed. However, low statistics at this intensity limits any confident conclusions for a peak at very small, non-zero ellipticity values. Lastly, analysis of TDSE results reveals an anomalous distribution for excitation out of the pm= +-1 initial ground state orbitals. Further experiments are required for solid conclusions as well as good agreement between TDSE results and experiments.
The last investigation explores the role of the CEP of a few-cycle pulse. For the first time, we show that excitation rates are highly dependent on both the peak intensity and CEP of the pulse. At a single intensity, TDSE calculations predict up to a 55% variation in excitation rates. Furthermore, the CEP dependent trends can vary significantly with small changes in the intensity, leading to a significant variation in the optimum CEP for maximum excitation yields. In the experiment, volume averaging reduces the maximum observable variation in the CEP dependent yields to 7%. Furthermore, they are still highly dependent on the exact in situ peak intensity of the experimental pulse with many peak intensities resulting in a variation below 5%. This places tight restrictions on conditions which allow successful observation of the variation in yields with varying CEP. Despite the inability to precisely determine the in situ experimental intensity, the agreement with the numerical predictions is very good which serves to validate the theoretical predictions.
The results from these studies reveal that the population of excited states are dependent on the intensity, polarization, and, in the case of few-cycle pulses, the CEP. If the intensity can be precisely controlled, selective excitation to the 5g and 6h states can be achieved with up to a 60% likelihood with the use of multi-cycle pulses. This is reduced with volume-averaging but these states still remain the most populated states. Knowing this, excitation to the metastable state can be increased through direct stimulation via additional radiation. Further studies to determine the precise efficiency of the process is required in order to evaluate it as a suitable replacement for current metastable generation techniques.Thesis (PhD Doctorate)

Full textAbstract:
La thématique abordée dans cette thèse relève de la manipulation d’un jet d’atomes d’argon métastables (Ar* ³P2) dans différentes configurations. Premièrement, je présente l’échange de métastabilité entre un atome au fondamental et un atome excité à de faibles énergies de centre de masse (entre 4 et 9 meV). Je propose également l’interprétation théorique par une approche semi-classique (approximation JWKB) qui se révèle validée, dans ce domaine d’énergies, en comparaison avec la résolution exacte de l’équation de Schrödinger radiale mettant en jeu les potentiels concernés par la collision. Les sections efficaces absolues d’échanges, déduites d’une analyse en temps de vol du signal métastable, permettent de réaliser une comparaison sans biais avec les prédictions théoriques. Les caractéristiques d’un jet ralenti par effet Zeeman sont dégradées par le processus de ralentissement et le rende difficilement utilisable en deçà de quelques dizaines de mètres par seconde. C’est pourquoi, dans un deuxième temps, je présente la réalisation d’un jet lent original, issu d’un piège magnéto-optique et présentant des caractéristiques remarquables. La vitesse est accordable entre 10 et 100 m/s, la dispersion de vitesse relative est très faible (6 % à 20 m/s) et le flux est conséquent (10⁹ Ar*/s/sr), pour une ouverture angulaire standard (35 mrad FWHM). Ce nouveau dispositif permet de présenter certaines questions d’interférométrie et d’optique atomique telles que les interactions atome-surface de type van der Waals et l’étude de potentiels comobiles ainsi que leurs applications dans la réalisation de milieux d’indice négatif ou de ralentisseursThe topic of this thesis concerns the manipulation of a metastable argon (Ar* ³p2) atomic beam in different configurations. Firstly, I present the metastability exchange between an atom in fundamental state and an excited atom at low center of mass energy (between 4 and 9 meV). I also propose theoretical interpretation by a semi-classical approach (JWKB approximation) which is validated, in this field of energies, compared to the exact solution of the Schrödinger radial equation with potentials involved in collision. The absolute exchange cross-sections, derived from a time of flight analysis of metastable signal, enable an unbiased comparison with theoretical predictions. The characteristics of a Zeeman slowedbeam are degraded by the process of slowing down and makes it difficult to use below a few tens of meters per second. Secondly, I present the realization of an original slow beam from a magneto-optical trap and having outstanding features. The atomic velocity is tunable between 10 and 100 m/s, the relative velocity dispersion is very low (6 % at 20 m/s) and the flow is substantial, (4.7×108 Ar*/s/sr), for a standard angular aperture (35 mrad FWHM). This new device can present some issues in atomic interferometry and atomic optics such as van der Waals atom-surface interactions or study co-moving potentials and their applications in negative-index media for matter wave or slowers

Full textAbstract:
One important phase in software development process is to create a design model of the system which follows all the architectural rules. Often the architectural rules are defined by the system architect and the system model is designed by the system designer. The architect defines the rules in a text file where no standard or pattern is followed. Therefore, there is always the risk of violating the architectural rules by the designer. So manual reviews on the system model should be done by the architect to ensure the system model is valid.In order to remove this manual checking which can be erroneous and time consuming ArCon (Architecture Conformance Checker) was developed by Combitech AB. ArCon is a tool which lets the architect define the architectural rules in the format of UML (Unified Modeling Language) models where the elements of the model have different meaning than the standard UML. ArCon can read this model and extract architectural rules from it and check the system model against those rules and then print all the rule violations.ArCon is an open source tool i.e. free for everyone to download and use. Currently, it supports Papyrus as the UML modeling tool. Papyrus is integrated to Eclipse platform and is a general purpose modeling tool. It supports users with all types of UML diagrams and elements.The idea for this thesis work was to implement a new feature for ArCon in order to facilitate the design process for system designers. The feature should provide the system designers only those types of elements which they are permitted to add to a specific fraction of the system model. The list of permitted element types should be extracted from the architecture model where all the architectural rules are defined in advance. This new support in ArCon was named Domain Specific Modeling (DSM) support.To evaluate the effect of DSM support on the system designers performance a few test sessions, called usability tests, were performed. The participants in the test sessions were a representative sample of software designers. After analyzing the data collected from the test sessions, the pros and cons of the new support were discovered. Furthermore, a few new ideas for enhancing DSM support were generated.

The GEANT4 physics simulation program is known to have errors in how hadronic interactions are implemented. This has the potential to cause errors in the Monte Carlos used to determine the expected neutron backgrounds in the MiniCLEAN single phase liquid argon WIMP detector. Elastic and inelastic collisions between neutrons and argon nuclei as well as neutron captures were simulated independently in order to characterize the accuracy of the implementation by GEANT4.9.3.pOl and GEANT4.9.5. The effective cross sections, angular distributions, photons, decay schemes, energy conservation, and momentum conservation were determined through analysis of the neutron tracks created by GEANT4. A large proportion of the interactions behave as expected, however energy and momentum are not conserved by varying degrees of severity with some GEANT4.9.3.pOl inelastic collisions resulting in over twice the correct amount of energy.

Full textAbstract:
Perimmäisenä ongelmana diplomityön taustalla on kaavoitusprosessin liian pitkänä koettu kesto tietyillä alueilla. Kaavoituksen useinkin liian pitkä kesto johtuu monista asioista, joista yksi on se, että prosessissa on mukana lukuisia eli sidosryhmiä. Osallisten suuri lukumäärä asettaa haasteita prosessin yhteistoiminnalle ja läpiviemiselle. Nykyään onkin vallalla käsitys, että kaavoitus on tulevaisuudessa menossa suuntaan, jossa yhteistoiminta on koordinoidumpaa ja erilaiset osalliset otetaan aktiivisesti huomioon jo aluesuunnitteluprosessin alkuvaiheessa.
Tällaista aluesuunnittelua on ottamassa käyttöön A-Insinöörit ensimmäisenä Suomessa uuden Kaupunginosan kehittämiskonseptin avulla. Kehittämiskonseptin perusajatuksena on konsulttityönä fasilitoida aluesuunnittelun yhteistoiminta hyvin osallistavalla toimintaperiaatteella ja aktiivisesti viedä suunnittelua eteenpäin. Konseptin tavoitteena on houkutteleva ja kaavataloudellisesti kestävä kaupunginosa, joka pystytään suunnittelemaan tehokkaalla aikataululla hyvän yhteistoiminnan ja ongelmien ennakoinnin ja ennaltaehkäisyn avulla. Kaupunginosan suunnittelukonseptissa kehitetään suunniteltavalle kaupunginosalle visio, joka konkretisoidaan erilaisiksi suunnitelmavaihtoehdoiksi ja lopulta tarkaksi suunnitelmaksi kaupunginosasta. Tämän diplomityön tarkoitus on tutkia kaavoituksen ja maankäytön problematiikkaa, jota A-Insinöörien prosessissa mahdollisesti kohdataan ja lisäksi kehittää konseptiin menetelmä, jolla visio- ja suunnitteluvaihtoehtoja voidaan vertailla ja arvottaa alueen loppukäyttäjän näkökulmasta.
Tutkimuksen päätavoite on siis kehittää menetelmä, joka toimii kaupunginosan kehittämiskonseptin tukena ja arvioi tämän eri vaiheiden tuloksia alueen loppukäyttäjän näkökulmasta. Loppukäyttäjää mallinnetaan asuinpientalon, asuinkerrostaloasunnon tai liiketilan ostajana ja loppukäyttäjän kokemaa arvoa mitataan maksuhalukkuuden avulla. Menetelmä mahdollistaa konseptisuunnitelmien vertailun ja rahamääräisen arvottamisen sekä vision arvioimisen yleisellä tasolla. Tutkimuksen toinen tavoite on tarjota toimeksiantajayritykselle kattava katsaus maankäytön ja kaavoituksen problematiikasta. Tutkimus käsittelee myös lukuisia arvonmääritys ja arviointityökaluja, jotka kaikki eivät sisälly lopulliseen menetelmään, joten tutkimuksen kolmas tavoite on tarjota lopullisen menetelmän lisäksi tietoa erilaisista arvonmääritys ja kaavaratkaisujen arviointityökaluista.
Johdannon jälkeen työn ensimmäinen luku eli teoriaosio käsittelee kaavoituksessa käytettyjä työkaluja kaavaratkaisujen arviointiin ja arvottamiseen. Teoriaosion lopussa on vielä kirjallisuuskatsaus arvonmääritykseen, jossa käsitellään ympäristöllisten ominaisuuksia, arkkitehtuurin, palveluiden ja liikenneyhteyksien hintavaikutusta kiinteistöihin aikaisemman tutkimuksen valossa. Seuraava eli kolmas luku on työn empiriaosio. Siinä käsitellään kaavoituksen ja maankäytön problematiikkaa laaja-alaisesti. Luvussa lähteinä toimivat aikaisempi tutkimus ja Oulun ja Espoon alueella tehdyt asiantuntijahaastattelut. Luvun lopussa kuvataan myös A-Insinöörien uusi liiketoimintakonsepti eli kaupunginosan kehittämiskonsepti, johon tämäkin työ liittyy. Konseptista kuvataan sen tavoitteet, prosessin kulku ja diplomityön liityntäpinnat. Neljäs luku toimii aiempien lukujen synteesinä ja siinä kuvataan viisivaiheinen menetelmä, joka toimii kaupunginosan kehittämiskonseptin tukena. Menetelmä kuvataan ensin kokonaisuudessaan, minkä jälkeen vaihe kerrallaan teoria- ja empiriaosioiden avulla perustellen. Lopuksi esitellään menetelmästä saatava informaatio ja sen käyttökohteet kaupunginosan kehittämiskonseptissa.

Full textAbstract:
Tämän tutkimuksen tavoitteena on perehtyä mobiilipalveluiden ja arvon ulottuvuuksiin asiakaslähtöisestä näkökulmasta. Asiakasarvon muodostumista tarkastellaan arvoulottuvuuksissa mobiilipalveluiden käytön kautta, jolloin arvon havaitsemisessa huomioidaan eri ulottuvuudet: tekninen, ajallinen, sosiaalinen, emotionaalinen ja arvon yhteisluonti. Arvo on subjektiivista asiakkaille, joten tutkimuksessa hyödynnetään fenomenologista lähestymistapaa asiakkaiden yksilöllinen konteksti ja käyttökokemukset huomioiden.
Tutkimusongelman tarkastelu tapahtuu asiakkaan arvonluonnin ja mobiilipalveluiden teorioiden pohjalta, joihin tutkimuskysymykset ja tutkimuksen teoreettinen viitekehys myös pohjautuvat. Tutkimuksen teoreettinen viitekehys on muodostettu mobiilipalveluiden tasot ja asiakkaan arvonluonnin ulottuvuudet yhdistämällä, jolloin ulottuvuuksissa esiintyy asiakasarvoa mahdollistavia arvotekijöitä mobiilipalveluiden kontekstissa. Teorian muodostuksessa hyödynnetään monipuolista asiakasarvon teoriaa ja mobiilipalveluiden ominaisuuksiin ja käyttöön liittyvää teoriaa.
Tutkimuksen empiirinen osuus on toteutettu laadullisella menetelmällä, ja tutkimuksen aineisto on kerätty teemahaastatteluja sekä havainnointia hyödyntäen. Tutkimuksen tyyppi on etnografinen, koska aineisto on kerätty eri tilanteissa ja eri menetelmiä hyödyntäen. Tutkimuksen kohderyhmä on nuoret, aktiiviset, useita mobiilipalveluja käyttävät aikuiset. Tutkimuksen kohderyhmäksi rajattiin nuoret aikuiset, koska aiemman tutkimuksen pohjalta heidän tiedetään yleensä käyttävän useita mobiilisovelluksia aktiivisesti. Tutkimuksen raportoinnin lähestymistapa on abduktiinen, ja empiirisessä aineiston analyysissä on käytetty teoriaohjaavaa sisällönanalyysiä teemoittelua hyödyntämällä.
Tutkimustulosten perusteella voidaan todeta, että asiakkaan mobiilipalveluiden käytössä vaikuttavat arvon eri ulottuvuudet. Mobiilipalveluiden käyttöönotossa esiintyy teknistä arvoa, joka riippuu ajallisesta arvosta mobiilipalveluiden käyttökontekstissa. Sosiaalista arvoa esiintyy mobiilipalveluiden sosiaalisia ominaisuuksia hyödyntäessä ja emotionaalinen arvo liittyy mobiilipalveluiden käytön positiivisiin tai negatiivisiin kokemuksiin. Mobiilipalveluiden suhteen arvotekijät, kuten yksityisyys ja luottamus mahdollistavat arvon yhteisluonnin syntymisen. Tämä tutkimus tarkentaa arvoulottuvuuksien arvotekijöitä mobiilipalveluiden käytössä, jolloin asiakkaan arvon muodostumista voidaan tarkastella yksityiskohtaisesti. Tutkimuksen teoreettisten ja liikkeenjohdollisten johtopäätösten myötä voidaan tarkentaa asiakkaan arvoulottuvuuksien havaitsemista eri mobiilipalveluiden konteksteissa.
Tutkimustulosten yleistettävyys arvon yksilöllisyyden ja rajatun kohderyhmän vuoksi on rajoittunutta. Tutkimuksen tavoitteeseen, eli mobiilipalveluiden arvotekijöiden havaitsemiseen asiakkaan arvoulottuvuuksissa, voidaan vastata tutkimuksen pohjalta.

Full textAbstract:
Cette thèse de création dont le maître objet est un moyen métrage – I Can Swim Home (I C S H) – s’inscrit dans le contexte du renouvellement des formes et des pratiques plastiques, dans un contexte où le climat général est en crise (environnement, sanitaire, économie, politique, institutionnel). Quels potentiels de l’art permettent-ils toutefois d’envisager un horizon commun ? Comment l’art et la recherche se proposent t-ils d’expérimenter et d’inventer des outils, des formes partageables, des alternatives concrètes pour renouveler nos modes d’échange, de partage, d’attention, d’adresse et d’imaginaire ? L’angle adopté dans ce doctorat ne consiste pas à recenser des formes plastiques au travers d’une histoire de l’art, mais à saisir ce qui, dans leur motif, relève du désir de « collectif » de l’artiste, et même du travail du « commun » comme œuvre principale. Il s’agit de revenir à cette vérité première de l’art comme « instauration » d’une communauté ouverte, tant par le concernement écologique de l’artiste que par son inscription dans une éthique du soin (care).De ce fait, le travail artistique oscille bien entre la polarité négative d’une crise de la production/reproduction à l’heure de l’Anthropocène et la polarité positive d’une quête d’identité par la pluralité des inscriptions environnementales et sociales de l’artiste. Quant aux pratiques mobilisées ici, en adéquation avec le parti-pris théorique,I Can Swim Home expérimente les voies de l’enquête sur la « reconnexion » (de l’artiste au milieu de l’art, de l’art au vivant) à partir de deux terrains méditerranéens, la Villa Arson et les Îles de Lérins. I Can Swim Home est une œuvre multiforme, constituée d’un film de fiction, de nombreux moments collectifs d’intensification de l’expérience esthétique, d’un carnet de recherche donnant libre cours aux intuitions et questionnements de l’artiste, et d’une analyse critique sur la pratique artistique mobilisant entités et personnes au bénéfice de l’invention plastiqueThis creation/thesis revolves around a medium-length film – I Can Swim Home (I Can Swim Home), questioning the renewal of forms and the artist’s practice in a context of global crisis (environmental crises, health crisis, economical, political and institutional crisis.) What leads may art provide toward envisioning a communal horizon? How may art, through research and experimentation, contribute to invent tools and practical alternatives allowing us to renew our modes of exchanging, sharing, attention, and imagining? This research doesnot aim to make an inventory of forms throughout art history, but to underline what, in the patterns encountered therein, might reveal the artist’s desire to invoke the collective, and to invoke commonality as the nature of the work itself. I C S H aims to go back to one of art’s primary truth: the “inauguration” of an open community, relying upon both the ecological concern of the artist and their adhesion to an ethics of care. The work of the artist will therefore oscillate between the negative pole of the crisis of production/reproduction in the era of the Anthropocene, and the positive pole of a quest for an identity through the plurality of their environmental and social inscriptions. In line with this theoretical stance, through the multiplicity of practices it implements, I C S H constitutes an experiment in investigating “reconnection” (between the artist and the art world, between art and the living), situated in two Mediterranean sites, the Villa Arson and the Lerins Islands.I Can Swim Home is a multiform comprehensive work including a fictional film, a number of collective moments of intensification of the aesthetical experience, a research notebook documenting the artist’s intuitions and questioning, and a critical analysis of the artist’s practice, inviting entities and individuals to partake into the aesthetic invention

Dans le chapitre un, nous avons présenté le fonctionnement et les différentes caractéristiques du Laser à Argon ionisé. Les principales hypothèses, concernant la création de l'inversion de population, sont énumérées. Dans le chapitre deux, après avoir modélisé le gain saturé du milieu amplificateur, nous avons calculé l'intensité émise par le Laser esclave en fonction: du gain non saturé, de l'intensité injectée et du déphasage entre l'onde injectée et l'onde auto-oscillante. Dans le chapitre trois, nous avons analysé les propriétés de la synchronisation en phase, et le transfert de stabilité du maitre oscillateur au Laser esclave, tant que leur décalage en fréquence est à l'intérieur de la plage d'accrochage par injection. Le chapitre quatre est consacré à l'étude d'un asservissement électronique de la cavité de l'esclave, afin de se prémunir des sauts en fréquence qui induisent des oscillations de la phase relative. Le dernier chapitre décrit les différents montages expérimentaux pour mesurer: le gain non saturé du milieu, les pertes par passage, la plage d'injection et l'intensité émise par l'esclave. En dernier lieu, nous avons asservi la cavité de l’esclave lorsque celui-ci est au-dessus du seuil d’oscillation.

La methode de datation a l'argon profite de differentes techniques; l'une conventionnelle mesure separement le potassium et l'argon, sa plage d'application a ete etendue aux ages tres recents. Elle utilise une comparaison (double pesee): l'argon de l'air permettant une haute resolution sur l'estimation de la teneur en argon radiogenique (technique cassignol). L'autre, mesure simultanement le potassium et l'argon, en spectrometrie de masse, par dosage de l'argon 39 forme a partir du potassium 39 lors de l'irradiation du materiel. Afin de disposer des performances des deux techniques un nouvel appareillage a ete concu. Ce spectrometre de masse 180 offre la possibilite de concentrer dans un petit volume les gaz extraits du mineral. Le pentacollecteur realise, mesure simultanement les masses 36 a 40. L'ensemble de l'appareil a ete etudie et semi automatise pour un emploi routinier et dans l'optique d'une future commercialisation. Les systemes de fusion ont ete assortis au type d'analyse: fusion laser, fusion hf, et fusion lampes. Des tests ont ete effectues sur des mineraux standards, une tentative d'application a la datation de la limite cretace paleogene est proposee

Tiivistelmä. Kehityspolitiikan raameissa ilmenevä tasa-arvopuhe on viime vuosikymmenien aikana noussut yhdeksi kehityspoliittisen keskustelun keskeisimmäksi viitoittajaksi. Myös Suomen kehityspolitiikassa tasa-arvo on nostettu entistä keskeisempään asemaan, ja Suomesta on jopa pyritty maalailemaan tasa-arvon mallimaata. Tästäkin huolimatta naisten ja tyttöjen asemaan keskittyvän painopistealueen rahoitus on laskenut huomattavasti kuluvan hallituskauden aikana. Tähän puheen ja toiminnan väliseen ristiriitaan perustuen tutkielmassa selvitetään, minkälaisia diskursseja sukupuolten välisestä tasa-arvosta Suomen kehityspolitiikan virallisdokumenteissa tuotetaan. Tutkielmassa ollaan kiinnostuneita erityisesti siitä, miten tasa-arvon diskurssit muotoutuvat suhteessa feministisen kehitystutkimuksen perinteisiin ja pyritään määrittämään, välittyykö tasa-arvo itsessään arvokkaana tavoitteena vai pyritäänkö sen kautta saavuttamaan laajemman skaalan kehitystuloksia.
Tutkielman teoria jakautuu kehityksen ja tasa-arvon käsittelyyn. Kehitystä analysoidaan itse käsitteen, kehitysteoreettisen muutoksen sekä suomalaisen kehityspolitiikan muotoutumisen näkökulmalta. Tasa-arvoa käsitellään laajana viitekehyksenä, jonka alle sijoittuvat sukupuolen käsite, naiset kehityksen kontekstissa, tasa-arvokeskeisen kehityspolitiikan muutos sekä vallitseva kehityspoliittinen teoria sukupuolinäkökulman valtavirtaistamisesta. Tutkielman aineisto koostuu 2000- ja 2010-luvuilla julkaistuista valtioneuvoston kehityspoliittisista ohjelmista, joitten pohjalta piirtyvien suuntaviivojen mukaisesti Suomen kehitysyhteistyötä toteutetaan. Aineistoa käsitellään diskurssianalyysilla pyrkien tulkitsemaan tapaa, jolla valta-asemassa olevat kielelliset merkitykset heijastelevat sosiaalista ja kulttuurista ympäristöä. Diskurssianalyysin keinoin aineistosta määritellään kolme päädiskurssia: kehityksen tuottamisen diskurssi, itseisarvon diskurssi sekä osaamisen diskurssi.
Tutkielman tulosten mukaan suomalainen kehityspuhe liittää sukupuolten välisen tasa-arvon osaksi laajempaa ihmisoikeuskysymystä, joka nitoo tasa-arvon, ihmisoikeudet, demokratian ja talouskasvun toisiaan tukeviksi tavoitteiksi. Tasa-arvo välittyy paikoitellen täytesanana, jota toistellaan osana mittavampia kokonaisuuksia tarkentamatta siihen konkreettisesti liittyviä tavoitteita ja esteitä. Kehityspolitiikan tuloksellisen toteutuksen kannalta olisi varteenotettavaa linkittää tasa-arvopuheeseen myös siihen liittyvät haasteet, kuten rakenteelliseen tasa-arvoon vaikuttamisen haastavuus.
