Consideration of methodological issues when using photo-elicitation in qualitative research

BACKGROUND: The use of photo-elicitation interviews (PEIs) has increased in popularity across a range of disciplines including healthcare. Although qualitative researchers have embraced PEIs as a creative way to explore people's experiences of their lives and environments, the methodological and practical aspects of using photographs have received little attention in the literature. AIM: To discuss the use of PEI techniques, including sourcing and using photographs. DISCUSSION: The authors discuss definitions of photo-elicitation, and explore the value of and difference between using photographs taken by the researcher and those taken by participants. They consider methodological issues in the context of a small-scale focus group study that used PEIs to explore young women's conceptualisations of teenage and older motherhood. CONCLUSION: Using photographs in research is far more complex than providing participants with cameras or presenting them with photographs. Researchers must be aware of the potential bias in the choice, selection and sequencing of photographs, as well as the methodological considerations associated with PEIs. IMPLICATIONS: for practice This article highlights the value of using photographs in qualitative research and presents some of the methodological issues that nurse researchers need to consider when designing and conducting research using photographs

The Definition and Significance of Intoxication in Australian Criminal Law: A Case Study of Queensland’s Safe Night out Legislation

Australian criminal law is being actively reconfigured in an effort to produce a more effective response to the problem of alcohol-related violence. This article uses the Safe Night Out Legislation Amendment Act 2014 (Qld) as a case study for two purposes: i) to introduce a set of conceptual tools and typologies that can be used to investigate the relationship between ‘intoxication’ and criminal law; and ii) to raise a number of concerns about how the effects of alcohol and other drugs are implicated in laws governing police powers, criminal responsibility and punishment. We draw attention to the different and sometimes inconsistent ways in which significance is attached to evidence of the consumption of alcohol and other drugs, as well as to variations and ambiguities in how legislation attempts to capture the degree of impairment or effects that are regarded as warranting the attachment of criminal law significance

Criminal law and the effects of alcohol and other drugs: a national study of the significance of intoxication in Australian legislation

Recent years have seen intense media scrutiny, concerted policy discussion and significant law reform on the relationship between the consumption of alcohol (and other drugs) and the commission of criminal offences. Much of the debate has been dominated by the view that, particularly for crimes of violence, the state of \u27intoxication\u27 produced by the consumption of alcohol and other drugs (\u27AOD\u27) should be regarded as an aggravating factor that adds to the seriousness of the harm done and warrants additional punishment. Some recent legislative reform measures have unambiguously embraced this position. As important as it is, treating intoxication as an aggravating factor is, in fact, only one of the ways in which Australian criminal law attaches significance to AOD consumption. We are currently undertaking a large-scale study of the \u27knowledges\u27 and assumptions about the relationship between intoxication and violence (and other offending and anti-social behaviours) that are reflected in Australian criminal laws. Our project compares legislative and judicial knowledges on \u27intoxication\u27 with scientific and social scientific expert knowledges on the effects of AOD, and the relationship between AOD consumption and violence and other criminal offending. It maps and assesses the multiple ways in which Australian criminal laws attach significance to the attribute of intoxication, and investigates the effects these approaches may have in practice. We aim to facilitate enhanced clarity, consistency and integrity in laws that attach penal significance to the fact of a person\u27s intoxication, and improve the criminal law\u27s capacity to meet the needs of the community with respect to the attribution of criminal responsibility for AOD-related anti-social behaviour, harms and risks

Fast preparation of single hole spin in InAs/GaAs quantum dot in Voigt geometry magnetic field

The preparation of a coherent heavy-hole spin via ionization of a spin-polarized electron-hole pair in an InAs/GaAs quantum dot in a Voigt geometry magnetic field is investigated. For a dot with a 17 ueV bright-exciton fine-structure splitting, the fidelity of the spin preparation is limited to 0.75, with optimum preparation occurring when the effective fine-structure of the bright-exciton matches the in-plane hole Zeeman energy. In principle, higher fidelities can be achieved by minimizing the bright-exciton fine-structure splitting.Comment: 8 pages, 10 figs, published PRB 85 155310 (2012

Polarization bistability and resultant spin rings in semiconductor microcavities

The transmission of a pump laser resonant with the lower polariton branch of a semiconductor microcavity is shown to be highly dependent on the degree of circular polarization of the pump. Spin dependent anisotropy of polariton-polariton interactions allows the internal polarization to be controlled by varying the pump power. The formation of spatial patterns, spin rings with high degree of circular polarization, arising as a result of polarization bistability, is observed. A phenomenological model based on spin dependent Gross-Pitaevskii equations provides a good description of the experimental results. Inclusion of interactions with the incoherent exciton reservoir, which provides spin-independent blueshifts of the polariton modes, is found to be essential.Comment: 5 pages, 3 figure

Homelessness and Contact with the Criminal Justice System: Insights from Specialist Lawyers and Allied Professionals in Australia

Lawyers and allied professionals who have experience supporting, advising and representing people experiencing homelessness are uniquely placed to identify problems with the operation of the criminal justice system—from policing to courts to punishment—and to conceive reform options. This article reports the findings of qualitative interviews with lawyers and allied professionals in all Australian states and territories. Participants identified multiple points where decisions about criminal law enforcement fail to take adequate account of the complex factors that underlie ‘offending’ by people experiencing homelessness, producing outcomes that exacerbate disadvantage. They advanced a range of proposals for reform directed at breaking the nexus between homelessness and criminalisation, including re-conception of the role of police, adoption of therapeutic jurisprudence (or ‘solution-focused’) models in criminal courts, and major changes to the use of fines as a criminal punishment.</jats:p

Voltage Controlled Hot Carrier Injection Enables Ohmic Contacts Using Au Island Metal Films on Ge

We introduce a new approach to creating low-resistance metalsemiconductor ohmic contacts, illustrated using high conductivity Au island metal films (IMFs) on Ge, with hot carrier injection initiated at low applied voltage. The same metallization process simultaneously allows ohmic contact to n-Ge and p-Ge, because hot carriers circumvent the Schottky barrier formed at metal/n-Ge interfaces. A 2.5x improvement in contact resistivity is reported over previous techniques to achieve ohmic contact to both n- and p- semiconductor. Ohmic contacts at 4.2 K confirm nonequilibrium current transport. Self-assembled Au IMFs are strongly orientated to Ge by annealing near the Au/Ge eutectic temperature. Au IMF nanostructures form, provided the Au layer is below a critical thickness. We anticipate that optimized IMF contacts may have applicability to many material systems. Optimizing this new paradigm for metalsemiconductor contacts offers the prospect of improved nanoelectronic systems and the study of voltage controlled hot holes and electrons.Peer reviewe
