Workplace Bullying among Business Professionals - Prevalence, Organisational Antecedents and Gender Differences (summary section only)

Workplace bullying can be defined as repeated and persistent negative acts that involve a power imbalance and create a hostile work environment. Partly because of the many negative consequences associated with the phenomenon, bullying has recently become the focus of many studies by contemporary organisational researchers. Drawing on a survey, this thesis provides information on the prevalence and forms of bullying among business professionals, a group of employees neglected in previous bullying research. The thesis follows a tradition among Nordic researchers that emphasises the role of the psychosocial work environment in bullying. In particular, it illustrates how high internal competition and a high degree of organisational politics in business life may lead employees to use bullying as a tactic to gain benefits over their colleagues. Furthermore, it explores the significance of gender in bullying in male-dominated work environments, with women tending to be subjected to more negative acts, tending to feel less capable to defend themselves in these situations, and tending to feel less reluctant to classify these experiences as bullying. In addition to the introductory essay, this thesis consists of a book chapter and four articles. These five papers address particular aspects of workplace bullying: the prevalence and forms of bullying, the significance of gender in bullying, and organisational antecedents of bullying.

This doctoral thesis analyses the concepts of good governance and good administration. The hypothesis is that the concepts are radically indeterminate and over-inclusive. In the study the mechanisms of this indeterminacy are examined: why are the concepts indeterminate; how does the indeterminacy work and, indeed, is it by any means plausible to try to define the concepts in a closed way? Therefore, the study focuses on various current perspectives, from which the concepts of good governance and good administration are relevant and what kind of discursive contents they may include. The approach is both legal (a right to good administration) and one of moral philosophy and discourse analysis. It appears that under the meta-discourse of good governance and good administration there are different sub-discourses: at least a legal sub-discourse, a moral/ethical sub-discourse and sub-discourses concerning economic effectiveness and the promotion of societal and economic development. The main claim is that the various sub-discourses do not necessarily identify each other s value premises and conceptual underpinnings: for which value could the attribute good be substituted in different discourses (for example, good as legal, good as ethical and so on)? The underlying presumption is, of course, that values are ultimately subjective and incommensurable. One possible way of trying to resolve the dynamics of possible discourse collisions is to employ the systems theory approach. Can the different discourses be interpreted as autopoietic systems, which create and change themselves according to their own criteria and are formed around a binary code? Can the different discourses be reconciled or are they indifferent or hostile towards each other? Is there a hegemonic super discourse or is the construction of a correct meaning purely contextual? The questions come back to the notions of administration and governance themselves the terms the good in its polymorphic ways is attempting to define. Do they engage different political rationalities? It can be suggested that administration is labelled by instrumental reason, governance by teleological reason. In the final analysis, the most crucial factor is that of power. It is about a Schmittian battle of concepts; how meanings are constructed in the interplay between conceptual ambiguity and social power. Thus, the study deals with administrative law, legal theory and the limits of law from the perspective of revealing critique.

Irradiation effects in graphene and related materials

Nanomaterials with a hexagonally ordered atomic structure, e.g., graphene, carbon and boron nitride nanotubes, and white graphene (a monolayer of hexagonal boron nitride) possess many impressive properties. For example, the mechanical stiffness and strength of these materials are unprecedented. Also, the extraordinary electronic properties of graphene and carbon nanotubes suggest that these materials may serve as building blocks of next generation electronics. However, the properties of pristine materials are not always what is needed in applications, but careful manipulation of their atomic structure, e.g., via particle irradiation can be used to tailor the properties. On the other hand, inadvertently introduced defects can deteriorate the useful properties of these materials in radiation hostile environments, such as outer space. In this thesis, defect production via energetic particle bombardment in the aforementioned materials is investigated. The effects of ion irradiation on multi-walled carbon and boron nitride nanotubes are studied experimentally by first conducting controlled irradiation treatments of the samples using an ion accelerator and subsequently characterizing the induced changes by transmission electron microscopy and Raman spectroscopy. The usefulness of the characterization methods is critically evaluated and a damage grading scale is proposed, based on transmission electron microscopy images. Theoretical predictions are made on defect production in graphene and white graphene under particle bombardment. A stochastic model based on first-principles molecular dynamics simulations is used together with electron irradiation experiments for understanding the formation of peculiar triangular defect structures in white graphene. An extensive set of classical molecular dynamics simulations is conducted, in order to study defect production under ion irradiation in graphene and white graphene. In the experimental studies the response of carbon and boron nitride multi-walled nanotubes to irradiation with a wide range of ion types, energies and fluences is explored. The stabilities of these structures under ion irradiation are investigated, as well as the issue of how the mechanism of energy transfer affects the irradiation-induced damage. An irradiation fluence of 5.5x10^15 ions/cm^2 with 40 keV Ar+ ions is established to be sufficient to amorphize a multi-walled nanotube. In the case of 350 keV He+ ion irradiation, where most of the energy transfer happens through inelastic collisions between the ion and the target electrons, an irradiation fluence of 1.4x10^17 ions/cm^2 heavily damages carbon nanotubes, whereas a larger irradiation fluence of 1.2x10^18 ions/cm^2 leaves a boron nitride nanotube in much better condition, indicating that carbon nanotubes might be more susceptible to damage via electronic excitations than their boron nitride counterparts. An elevated temperature was discovered to considerably reduce the accumulated damage created by energetic ions in both carbon and boron nitride nanotubes, attributed to enhanced defect mobility and efficient recombination at high temperatures. Additionally, cobalt nanorods encapsulated inside multi-walled carbon nanotubes were observed to transform into spherical nanoparticles after ion irradiation at an elevated temperature, which can be explained by the inverse Ostwald ripening effect. The simulation studies on ion irradiation of the hexagonal monolayers yielded quantitative estimates on types and abundances of defects produced within a large range of irradiation parameters. He, Ne, Ar, Kr, Xe, and Ga ions were considered in the simulations with kinetic energies ranging from 35 eV to 10 MeV, and the role of the angle of incidence of the ions was studied in detail. A stochastic model was developed for utilizing the large amount of data produced by the molecular dynamics simulations. It was discovered that a high degree of selectivity over the types and abundances of defects can be achieved by carefully selecting the irradiation parameters, which can be of great use when precise pattering of graphene or white graphene using focused ion beams is planned.

Hostility: A prospective study of the genetic and environmental background and associations with cardiovascular risk

Hostility is a multidimensional construct having wide effects on society. In its different forms, hostility is related to a large array of social and health problems, such as criminality, substance abuse, depression, and cardiovascular risks. Identifying and tackling early-life factors that contribute to hostility may have public health significance. Although the variance in hostility is estimated to be 18-50 percent heritable, there are significant gaps in knowledge regarding the molecular genetics of hostility. It is known that a cold and unsupportive home atmosphere in childhood predicts a child s later hostility. However, the long-term effects of care-giving quality on hostility in adulthood and the role of genes in this association are unclear. The present dissertation is part of the ongoing population-based prospective Young Finns study, which commenced in 1980 with 3596 3-18-year-old boys and girls who were followed for 27 years. The specific aims of the dissertation were first to study the antecedents of hostility by looking at 1) the genetic background, 2) the early environmental predictors, and 3) the gene environment interplay behind hostility. As a second aim, the thesis endeavored to examine 4) the association between hostility and cardiovascular risks, and 5) the moderating effect of demographic factors, such as gender and socioeconomic status, on this association. The study found potential gene polymorphisms from chromosomes 7, 14, 17, and 22 suggestively associated with hostility. Of early environmental influences, breastfeeding and early care-giving were found to predict hostility in adulthood. In addition, a serotonin receptor 2A polymorphism rs6313 moderated the effect of early care-giving on later hostile attitudes. Furthermore, hostility was shown to predict cardiovascular risks, such as metabolic syndrome and inflammation. Finally, parental socioeconomic status was found to moderate the association between anger and early atherosclerosis. The new genetic and early environmental antecedents of hostility identified in this research may help in understanding the development of hostility and its health risks, and in planning appropriate prevention. The significance of early influences on this development is stressed. Although the markers studied are individual- and family-related factors, these may be influenced at the societal level by giving accurate information to all individuals concerned and by improving the societal circumstances.
