Orange Zinc Germanate with Metallic Ge-Ge Bonds as a Chromophore-Like Center for Visible-Light-Driven Water Splitting

The efficiency of solar-energy-conversion devices depends on the absorption region and intensity of the photon collectors. Organic chromophores, which have been widely stabilized on inorganic semiconductors for light trapping, are limited by the interface between the chromophore and semiconductor. Herein we report a novel orange zinc germanate (Zn-Ge-O) with a chromophore-like structure, by which the absorption region can be dramatically expanded. Structural characterizations and theoretical calculations together reveal that the origin of visible-light response can be attributed to the unusual metallic Ge-Ge bonds which act in a similar way to organic chromophores. Benefiting from the enhanced light harvest, the orange Zn-Ge-O demonstrates superior capacity for solar-driven hydrogen production.

Experiencing Youth Justice: Process, Meaning and Legitimacy

Reform of the youth justice system, including the wide incorporation of restorative justice approaches, was a central component of the Criminal Justice Review (2000). Following the devolution of policing and justice powers to the Assembly, the Youth Justice Review (2011) made a series of recommendations for further reforms. These included proposals for the introduction of a statutory time limit in youth cases to tackle avoidable delay. Strengthening legitimacy and advancing rights-based approaches are key themes underpinning the recommendations of Youth Justice Review (2011). Young people’s views of justice within the system are critical to our understanding of how such aims can be achieved. This presentation is based on findings from a longitudinal qualitative study exploring young people’s experiences of transitions into and from custody in the Juvenile Justice Centre. Using a life-history approach young people’s experiences of justice at various stages of the criminal justice process and in the wider context of their lives is explored. Key issues such as social contexts, legitimacy and perceptions of fairness are highlighted and the implications of this for system reform are critically examined.

Punishment, youth justice and cultural contingency: Towards a balanced approach

Reflecting developments in the broader penological realm, accounts have been advanced over the last number of decades about a ‘punitive turn’ in the youth justice systems of Western democracies. Against the background of this work, this project seeks to identify convergent and divergent trends in the youth justice systems of England, the Republic of Ireland and Northern Ireland as well as the rationalities and discourses animating these. The results lend support to research emphasising the continued salience of national, regional and local factors on penal outcomes but also suggest the need to steer an analytical path somewhere between nomothetic (convergent) and idiographic (divergent) accounts.

"Things I did not know”: Retrospectives on a Canadian rural male youth suicide using an instrumental photo voice case study

In Canada, it is young rural based men who are at the greatest risk for suicide. While there is no consensus on the reasons for this, evidence points to contextual social factors including isolation, lack of confidential services and pressure to uphold restrictive norms of rural masculinity. In this article we share findings drawn from an instrumental photo voice case study to distil factors contributing to the suicide of a young Canadian rural based man. Integrating photo voice methods and in-depth qualitative we conducted interviews with 7 family members and close friends of the deceased. The interviews and image data were analyzed using constant comparative methods to discern themes related to participants’ reflections on and perceptions about rural male suicide. Three inductively derived themes, “Missing the signs”, “Living up to his public image” and “Down in Rural Canada ” reflect the challenges that survivors and young rural men can experience in attempting to be comply with restrictive dominant ideals of masculinity. We conclude that community based suicide prevention efforts would benefit from gender-sensitive and place specific approaches to advancing men’s mental health by making tangibly available and affirming an array of masculinities to foster the well-being of young rural based men.

Growing Up On an Interface: Findings and Implications for the Social Needs, Mental Health and Lifetime Opportunities of Belfast Youth

In this research we aimed to find out what types of risk (if any) affected young people and children growing up in places of high religious segregation or what we normally call interface communities. This is important as we know that risk and experiences of harm and violence can have negative impacts upon development, emotional well-being and future prospects. It is important to understand what types of risk affect young people and children so as we can respond to these in terms of aiding better personal and community development with regard to health, work, education and wider opportunities.

Modeling the Rossiter-McLaughlin Effect: Impact of the Convective Center-to-limb Variations in the Stellar Photosphere

bservations of the Rossiter–McLaughlin (RM) effect provide information on star–planet alignments, which can inform planetary migration and evolution theories. Here, we go beyond the classical RM modeling and explore the impact of a convective blueshift that varies across the stellar disk and non-Gaussian stellar photospheric profiles. We simulated an aligned hot Jupiter with a four-day orbit about a Sun-like star and injected center-to-limb velocity (and profile shape) variations based on radiative 3D magnetohydrodynamic simulations of solar surface convection. The residuals between our modeling and classical RM modeling were dependent on the intrinsic profile width and v sin i; the amplitude of the residuals increased with increasing v sin i and with decreasing intrinsic profile width. For slowly rotating stars the center-to-limb convective variation dominated the residuals (with amplitudes of 10 s of cm s−1 to ~1 m s−1); however, for faster rotating stars the dominant residual signature was due a non-Gaussian intrinsic profile (with amplitudes from 0.5 to 9 m s−1). When the impact factor was 0, neglecting to account for the convective center-to-limb variation led to an uncertainty in the obliquity of ~10°–20°, even though the true v sin i was known. Additionally, neglecting to properly model an asymmetric intrinsic profile had a greater impact for more rapidly rotating stars (e.g., v sin i = 6 km s−1) and caused systematic errors on the order of ~20° in the measured obliquities. Hence, neglecting the impact of stellar surface convection may bias star–planet alignment measurements and consequently theories on planetary migration and evolution.
