Image is an important carrier for people to get information on a daily basis. However the spread of CG produced for malicious purposes may disrupt social order and even undermine social stability. Therefore, the accurate detection of CG and PG is of great significance. In this paper, we (1) introduce 11 approaches that apply deep learning to the implementations of CG detection, and divide them into 4 categories based on the network structure; (2) give an introduction to the available datasets; (3) design a series of experiments to test the detection performance of each approach,then analyze the experimental results; The experimental results show that most approaches can differentiate CG from PG, while the detection accuracy and efficiency of each model are different. Nevertheless none of these methods is valid when the images tampered by noise. Above all (4) summarize the problems and challenges in this field, and look forward to the trends in future research. INDEX TERMS Computer-generated images and photographs, deep learning-based classification, digital image forensics, the state of art of detection approaches.

This paper examines this complex programmatic issue from a community-based participatory research approach for program adaptation that emphasizes motivating community participation to enhance program outcomes. Several issues, key concepts, and implementation strategies are presented under a strategic approach to address issues of fidelity and adaptation. Despite the noted tension between fidelity and adaptation, both are essential elements of prevention intervention program design and they are best addressed by a planned, organized, and systematic approach. Towards this aim, an innovative program design strategy is to develop hybrid prevention programs that "build in" adaptation to enhance program fit while also maximizing fidelity of implementation and program effectiveness.

While in prison, most parents maintain at least some contact with their families. A positive connection with family during imprisonment is hypothesized to improve long-term success after release. One way in which departments of corrections attempt to facilitate positive connections with family is through prison-based parenting programs. One such program, developed in collaboration with the Oregon Department of Corrections, is the cognitive-behavioral parent management training program Parenting Inside Out (PIO). Outcomes due to PIO were examined within the context of a randomized controlled trial. Incarcerated parents from all correctional facilities in the state of Oregon were recruited to participate, and eligible parents who consented (N = 359) were transferred to participating releasing institutions. After initial assessment, parents were randomized to condition (i.e., PIO “intervention” condition or services-as-usual “control” co...

Grounded theory qualitative procedures were used to analyze the needs assessment data from 31 Latinx immigrant farmworker residents and key informant interviews as well as four focus groups with resident youth and parents. A theoretical model of how key family-based health behaviors can both confer risk for and protection against negative physical, mental, and social health outcomes among Latinx farmworking communities emerged. Six primary areas of concern emerged from these data, leading to the identification of primary health promotion intervention needs with three foci: (a) the provision of sustainable supports and resources, (b) skill development so that individuals could successfully negotiate identified challenges, and (c) greater community efficacy. Findings underscore the importance of social support and resource accessibility for Latinx immigrant po...

Participants were 278 children attending kindergarten or first grade who were identified as "at risk" for adjustment problems during adolescence. The program was delivered through established nonprofit community-based organizations. Mentors were hired to work full time and were provided training, supervision, and support to work individually with small numbers of children. Recruitment took place across a 3-year period. Random assignment to the intervention condition or a services as usual control condition was conducted at the level of the individual, blocking on school and child sex. After the initial assessment, follow-up assessments were conducted every 6 months. Differences in growth curves across the elementary school years were examined in intent-to-treat analyses. Significant eff...

Research paper thumbnail of A Tale of Two Measures: Concordance Between the ARSMA-II and the BIQ Acculturation Scales Among Latino Immigrant Families

Different acculturation measures are often assumed to be interchangeable, although this assumption is rarely tested empirically. The purpose of the present study was to examine the overlap between 2 commonly used measures of acculturation among individuals of Latino/Hispanic ancestry in the United States, the Acculturation Rating Scale for Mexican Americans II (ARSMA-II) and the Bicultural Involvement Questionnaire-Short Version (BIQ-S). Specifically, we examined the ways in which scores from the 2 measures relate to one another, as well as similarities versus differences in the ways they predict external variables of interest (e.g., family functioning, parenting, and youth adjustment) that acculturation is known to influence. Fi...

Multiple methods and agents were used in assessing family process variables and child outcomes. Findings suggest that greater accumulations of family transitions were associated with poorer academic functioning, greater acting-out behavior, and worse emotional adjustment for boys. However, in all three cases, these relationships were mediated by parenting practices: Parental academic skill encouragement mediated the relationship between transitions and academic functioning, and a factor of more general effective parenting practices mediated the relationships between transitions and acting out and emotional adjustment.

Estimates also suggest that millions of additional children have a parent in jail, although the actual number of affected children is unknown because this information is not systematically collected by correctional, school, or other service systems. The children of parents involved with the criminal justice system are at risk for involvement in the child welfare system. In most studies, from 5 to 10% of incarcerated parents have children in foster care per se, but involvement with the system at large may be much greater, particularly for incarcerated mothers. In this presentation, we describe the adaptation process we used with evidence-based parent management training interventions to create Parenting Inside Out (PIO). Working closely with inmates, the caregivers of their children, and parent educators working with correctional settings, ...

In the present paper, the authors review challenges encountered when integrating minimally-invasive stress-related biomarkers (e.g., blood pressure, Epstein-Barr Virus [EBV] antibodies, C-reactive protein [CRP], and salivary cortisol), as well as anthropometric (e.g., height, weight, waist circumference) and metabolic measures (e.g., glucose, cholesterol), into research with Latino immigrant adults and families in Oregon, USA. Finally, the authors present lessons learned and discuss strategies to support the full engagement of Latino immigrants as participants in studies that rely on the collection of biological data as a central component of research into psychosocial stress and its effects.
