Ancient environmental DNA (aeDNA) from lake sediments has yielded remarkable insights for the reconstruction of past ecosystems, including suggestions of late survival of extinct species. However, translocation and lateral inflow of DNA in sediments can potentially distort the stratigraphic signal of the DNA. Using three different approaches on two short lake sediment cores of the Yamal peninsula, West Siberia, with ages spanning only the past hundreds of years, we detect DNA and identified mitochondrial genomes of multiple mammoth and woolly rhinoceros individuals-both species that have been extinct for thousands of years on the mainland. The occurrence of clearly identifiable aeDNA of extinct Pleistocene megafauna (e.g. >400 K reads in one core) throughout these two short subsurface cores, along with specificities of sedimentology and dating, confirm that processes acting on regional scales, such as extensive permafrost thawing, can influence the aeDNA record and should be accounted for in aeDNA paleoecology.

This paper advances scholarly debate on the contradictions of environmental risk management measures by analyzing the determinants of flood insurance coverage among a sample of 403 residents in New Orleans, a city undergoing rapid transformation due to post-Katrina rebuilding efforts and anthropogenic modifications of climate, hydrology, and ecology. The paper focuses on several predictors including subjective flood risk perception, trust in government officials, sociodemographic characteristics, and experience with flood damage. Using binary logistic regression, the results show that the likelihood of having flood insurance coverage is associated with past flood damage and socioeconomic status. Older people (over age 65) are more likely to have flood insurance than younger residents. Race, gender, trust, and perceived flood risk are not statistically significant predictors of flood insurance. We connect our findings to the paradoxes and conflictual dynamics of flood insurance, a major risk mitigation measure. As we point out, in flood-prone cities like New Orleans, flood insurance operates as a double whammy: uninsured or underinsured homes face pervasive risk of both flooding and rising insurance premiums under the conditions of global climate change.

Integrity is an ongoing concern in the public sector. Contemporary examples include fraud incidents, ethical violations, theft, and a disregard of legal advice resulting in significant harms to the public. Public service integrity management systems are interconnected frameworks of legislation and institutions intended to reduce such incidents, including Codes of Conduct (CoCs). A CoC is typically defined as a written set of norms that outline virtuous or desired behaviours, often creating or linking to sanctions for violations. Despite matters of integrity and corruption being a high concern for citizens, no method exists to compare monitoring, reporting, and review of CoCs across jurisdictions. We developed and applied a method to assess CoC implementation using specific assessment criteria developed by reviewing available content across jurisdictions and the current literature on CoCs and integrity management. Our results reveal substantial inconsistency between jurisdictions and a lack of available or accessible data for many CoC elements. Our method serves both as a tool for analysis of the effectiveness of CoCs over time and as an assessment of how jurisdictions are currently reporting on their compliance with their own CoCs. Points for practitioners: A lack of evidence exists in terms of how CoCs are monitored, reported on, and reviewed.As a first stage of a research program, we develop and apply a method to all Australian states, territories, and the Australian Public Service to compare the monitoring, reporting, and review activities undertaken by these jurisdictions.Application of the method reveals opportunities for jurisdictions to improve the availability and accessibility of CoC data collection, reporting, and review.Auditors General and Public Accounts Committees should consider this method as part of their works programs and potentially use it to inform their scrutiny programs and requirements for performance and annual reporting.Public Service Commissions could find the data useful in adapting and improving their CoC monitoring, reporting, and review systems.

Objective: The purpose of the study was to investigate the differences between intimate partner violence (IPV) and parenting attitudes by race by comparing demographic, parenting, and IPV indicators for African American and White men. Method: The study employed a nonequivalent, control group design in a secondary analysis of 111 men. Results: Analyses indicated that (1) African American men had more children; (2) chi-square tests revealed no statistically significant differences between African American and Caucasian men with respect to IPV perpetration and parenting attitudes; and (3) a logistic regression model indicated that the number of children and a higher risk category for parenting attitudes were significant predictors of race group membership. Conclusion: These findings reveal that having more children is related to a higher level of stress on intimate partner relationships, and these stressors are not evenly distributed across racial groups. Batterer intervention programs should include parenting skills to help perpetrators better cope with such stresses.

Most citizen science research inherently separates the observer (citizen science participant) from the observation (e.g. data point), placing artificial boundaries around what matters and how it comes to matter. We apply three elements of the philosophical framework of agential realism to reveal a more complex picture of how data arise within citizen science programmes, and its meaning to both the practice of science and the citizen science participant: 'intra‐action' (all entities have agency and are entangled with one another); 'material becoming' (what comes to matter); and 'responsibility' (accountability for what comes to matter and what is excluded from mattering).We draw on a case study of FrogID—an Australia‐wide citizen science program focused on calling frogs, with over 42,000 participants and over 1 million frog records. We conducted semi‐structured interviews with 30 FrogID users, completing two rounds of thematic and relational coding.Our findings reveal that as a consequence of their recording behaviours, FrogID participants become increasingly entangled with the nocturnal environment, with sound and with their own self. Expanding and reciprocal relationships and experiences shape the nature and frequency of their recordings.Second, meaning influences what comes to matter (i.e. what is recorded and submitted) for FrogID participants. We reveal meaning related to feedback (recognition and thus reciprocity), others (social networks and participation with family and friends) and the self (physical and mental well‐being and identity formation/becoming). These different forms of meaning influenced engagement with app use.Third, participants communicated responsibilities related to their involvement in citizen science, including responsibilities to create knowledge (e.g. longitudinal data collection), to conserve (e.g. actively conserving frog, formally committing areas to conservation) and to educate self and others (e.g. skills and competencies required for environmental action).Synthesis and applications: By recognizing a more comprehensive set of intra‐actions, beyond the observer and the observation, agential realism can reveal when, why and how citizen science observations are made; what observations come to matter and why; and how people can create a more just world. Agential realism can shape how citizen science participation, retention and biodiversity data generation are founded. We propose three opportunities for citizen science programs based on these findings. Read the free Plain Language Summary for this article on the Journal blog.

In the United States, the judicial system response to violence between intimate partners, or intimate partner violence (IPV), typically mandates that adjudicated perpetrators complete a batterer intervention program (BIP). The social science data has found that these programs, on the whole, are only minimally effective in reducing rates of IPV. The authors examined the social science literature on the characteristics and efficacy of BIPs. More than 400 studies were considered, including a sweeping, recently conducted survey of BIP directors across the United States and Canada. Results of this review indicate that the limitations of BIPs are due, in large part, to the limitations of current state standards regulating these programs and, furthermore, that these standards are not grounded in the body of empirical research evidence or best practices. The authors, all of whom have considerable expertise in the area of domestic violence perpetrator treatment, conducted an exhaustive investigation of the following key intervention areas: overall effectiveness of BIPs; length of treatment/length of group sessions; number of group participants and number of facilitators; group format and curriculum; assessment protocol and instruments; victim contact; modality of treatment; differential treatment; working with female perpetrators; working with perpetrators in racial and ethnic minority groups; working with lesbian, gay, bisexual, and transgender (LGBT) perpetrators; perpetrator treatment and practitioner–client relationships; and required practitioner education and training. Recommendations for evidence-based national BIP standards were made based on findings from this review.

In this article, we apply three theoretical frameworks, poststructural feminism, queer, and sociology of gender to the issue of intimate partner violence (IPV) in order to better account for heterosexual female perpetration and same-sex IPV. Although the traditional feminist paradigm-that assumes men use violence as an extension of patriarchy against their female victims-has been useful in explaining some instances of IPV, it does not adequately frame instances of heterosexual female perpetration and IPV in same-sex relationships. Therefore, in this article we seek to add to existing literature by re-theorizing IPV using poststructural feminism, queer, and sociology of gender perspectives, and their attendant understanding of power as dynamic, fluid, and relational and gender as both interactional and structural, in order to open up new ways of framing IPV and encourage new lines of empirical research resulting in better policy proscriptions and treatment interventions.

The Elizabeth Wisner Social Welfare Center for Families and Children is a community-based research center within the School of Social Work at the Tulane University. The Wisner Center primarily supports research projects that examine the causes and consequences of intimate partner violence, promote the development of new frameworks for understanding family violence, and utilize findings from research to inform interventions directed at reducing violence in families and communities. This article describes the history, structure, and funding resources of the Wisner Center and offers an overview of affiliated research projects and publications. Finally, this article illustrates the vital role of the Wisner Center in promoting the research agendas of junior faculty competing for funding within the Tulane University's decentralized management center model.

Biodiversity conservation programs that appeal to landholders' motivations and minimise their barriers to participation may result in both increased uptake rates and improved ecological outcomes. To understand their motivations and barriers to conserve biodiversity, qualitative interviews were conducted with 45 landholders who had participated in one of three different programs in Queensland, Australia. The results revealed that the landholders' decisions to participate depended on the level of formal biodiversity protection offered by the program, potential changes to their property rights, personal benefits of participation, and the program objectives. Landholders' motivations related to conservation, production, financial and experimental imperatives. Common barriers to participation were lost productivity, different interpretations of what constituted "conservation", and limits to future development and land use options. Voluntary and economic policy instruments can be used to stimulate participation and overcome barriers, but must be applied with care to reduce the creation of perverse ecological outcomes, such as slippage and low additionality.
