Mapping Social Cohesion Survey, 2023
No full textThe Scanlon Foundation Research Institute’s Mapping Social Cohesion study provides a series of detailed surveys on social cohesion, immigration and other topical social issues in Australia. The surveys provide a key source of information to understand patterns and change in the perceptions, attitudes and experiences of Australians across society and within social and demographic groups. The 2023 survey is the seventeenth national survey that the Scanlon Foundation has conducted since 2007. The survey is administered on the Social Research Centre’s Life In AustraliaTM (LinA) panel, Australia’s first and only national probability-based online panel. The 2023 survey employed a questionnaire comprising over 100 substantive and demographic questions in ten modules. The sample included 7,454 respondents
Physics beyond the standard model:: supersymmetry, dark matter, and LHC phenomenology
No full textThe Standard Model (SM) of particle physics is remarkably successful and has survived two decades of precision tests at high energy particle accelerators. However, it is known to be incomplete, and there are reasons to believe that there is new physics at energy scales that will soon be probed in greater detail than ever before by the Large Hadron Collider (LHC), a proton-proton accelerator being built near Geneva.
This thesis contains a diverse set of topics that may broadly be described as physics beyond the SM.
In Chapter 2, implications of current experimental constraints are presented for the stop masses and mixing in the Minimal Supersymmetric Standard Model (MSSM), a well-motivated candidate for physics beyond the SM. It is found, for example, that lower bounds on the stop masses are as large as 1 TeV assuming no stop-mixing.
Chapter 3 presents the regions in the MSSM with the minimal amount of fine-tuning of electroweak symmetry breaking. The minimal amount of tuning increases enormously for a Higgs mass beyond 120 GeV.
Supersymmetry cannot be an exact symmetry, and one possibility is that our Universe is in a long-lived metastable state with broken supersymmetry. In Chapter 4, a generic model with this property is constructed in which all the relevant parameters, including the supersymmetry breaking scale, are generated dynamically. This model has several interesting model-building features including an explicitly and spontaneously broken R-symmetry, a singlet, a large global symmetry, naturalness, renormalizability, and a "pseudo-runaway'' direction.
In Chapter 5, a simple extension of the SM with weakly interacting non-chiral dark matter particles is presented. Such particles can be detected at a future direct-detection experiment.
There are a wide variety of possible discovery signatures for new physics at the LHC. A discovery signature with a large SM background that has not been well studied involves multi-jet events without leptons and/or missing energy.
In Chapter 6, it is found that using innovative search strategies pair production of new coloured adjoint fermions producing a pure six-jet final state can be detected up to a mass of about 650-700 GeV with 10 fb-1 of integrated luminosity.Ph.D.Includes bibliographical references

The 2022 survey employed a questionnaire comprising 95 substantive and 21 demographic questions in ten modules. The sample included 3,572 respondents. Developed using funding from the Department of Home Affairs, this Index will be published every two years, and combines the data contained in this Mapping Social Cohesion Survey dataset with objective indicators from the Australian Bureau of Statistics and other sources. The objective data is contained in the Mapping Social Cohesion 2021 report

Narratives of cultural diversity among older white people in rural Australia
No full textThis study investigated the ways older white people living in rural Australia construct narratives about engaging with people from diverse backgrounds and Aboriginal people. It considered how whiteness shaped these narratives by focusing on notions of rurality, multiculturalism and Indigeneity. The findings point to the ways whiteness constrains possibilities for the emergence of conviviality in rural Australia.</p

No full textA Conceptual Framework to Map Responses to Hate Crime, Hate Incidents and Hate Speech: The Case of Australia
No full textResponses to hate crimes, hate incidents and hate speech are characterised by an exceptional fragmentation in terminology and lack of coordination among governmental and non-governmental organisations. This article proposes a new conceptual framework to map the diversity of responses to hate crime, hate incidents and hate speech, with the aim of assessing gaps and needs in this important policy area. Using Australia as a case study, we create and analyse a database of 222 organisations running activities focusing on tackling hate against different target groups. The results highlight an uneven distribution of efforts across different geographical areas, types of activities and target groups. The majority of anti-hate efforts, especially by government organisations, focus on awareness raising and education rather than victim support and data collection. Racial and religious hate are the main foci of anti-hate efforts, compared to other forms of hate, such as anti-LGBTIQ+ and disablist hate
Venture Capital - An analysis of organizational structures of VC funds in Europe and the effects on agency costs
No full textThe present thesis investigates agency problems which occur within the investormanager
relationships of VC firms. The focus is on early stage companies and VCs.
Furthermore, it presents the status-quo of the structures of some selected VC
organizations in Europe and allows deep insights in the practices of the business of
VCs. The portfolio monitoring and the investor-founder relations are analyzed with
regard to the concepts of the principal-agent relationship, informational asymmetries,
moral hazard and adverse selection.
The underlying empirical approach of this thesis is based on explorative, semistructured,
qualitative expert interviews. The author conducted interviews with both
parties, investors and founders. The emerging hypotheses of these interviews allow
recommendations for action for decision makers of VCs when structuring the
organization of the respective VC to reduce specific agency costs. It is very important
for VCs to be transparent in terms of the investment focus and contact persons that are
involved in the cooperation with the respective company for example. This reduces
communication and coordination efforts ex ante and therefore, needless costs could be
avoided. Another object of study is the consideration whether a specialized or a
generalist structure is beneficial inside the investment teams of VCs. Besides, the
thesis helps entrepreneurs to develop an orientation for the work and communication
with VC-investors. Further research, especially quantitative studies are needed to
prove the findings of this thesis
