Children picturing their own worlds: Using photovoice to amplify children's voice in sociological research.

This research note highlights an emerging transdisciplinary research method-photovoice-and why it is particularly suited for sociological studies of children and youth. Traditional social science data collection methods can be limited in their ability to capture both the depth and breadth of childhood experiences and children's perceptions of their experiences. We describe an emerging method, photovoice, that is used more frequently in other disciplines, and its suitability for sociologically studying youth and children. We describe the limitations of traditional social science methods and how photovoice can help overcome some of these limitations. Photovoice engages participants as lived experts who contribute to both the data collection and analysis in an individual and collective manner. Through taking photos and discussing their meaning, participants can share abstract feelings and discuss sensitive topics in an imaginative format and express themselves creatively. We describe how previous research has used photovoice to work with youth from vulnerable circumstances and those who have experienced trauma as well as demonstrate how photovoice is well situated to bolster the tenets of sociological research.

Study protocol for a randomized controlled trial of the Parent-Child Assistance Program: a case management and home visiting program for people using substances during pregnancy.

BACKGROUND: Perinatal substance use can have significant adverse effects on maternal and child health and family stability. Few interventions are specifically designed to address this significant public health problem. The Parent-Child Assistance Program (PCAP) is a 3-year case management and home-visiting intervention that seeks to help birthing persons with at-risk substance use during pregnancy to achieve and maintain substance use disorder recovery and avoid exposing future children to substances prenatally. At-risk refers to a level of substance use that creates problems in the individuals' lives or puts them or their children at risk of harm either prenatally or postnatally. Although the program has consistently shown substantial pre- to post-intervention improvements in its participants, PCAP remains to be tested with a rigorous randomized controlled trial (RCT). This study protocol describes a randomized controlled trial that aims to examine the effectiveness of the intervention compared to services as usual in affecting primary outcomes related to substance use and family planning. Secondary outcomes will concern connection to recovery support services and family preservation. METHODS: Using an intent-to-treat design, the study will recruit from two metro areas in Oklahoma and enroll 200 birthing individuals who are pregnant or up to 24 months postpartum with at-risk substance use during their current or most recent pregnancy. Participants will be randomly assigned, stratified by location, to receive either PCAP or services as usual for 3 years. Participants in the PCAP condition will meet with their case manager approximately biweekly over the course of the intervention period, in their local communities or in their own homes whenever possible. Case managers will assist with goal setting and provide practical assistance in support of participants' goals. Primary and secondary outcomes will be assessed at baseline and 12, 24, and 36 months post-baseline using the Addiction Severity Index interview and a self-administered survey. DISCUSSION: Results from this trial will help to gauge the effectiveness of PCAP in improving parent and child well-being. Results will be reviewed by federal clearinghouses on home-visiting and foster care prevention to determine the strength of evidence of effectiveness with implications for federal financing of this program model at the state level.

Commercial characteristics of coffee seedlings produced with different sources of phosphorus and plant growth-promoting bacteria.

Considered the economic engine of many countries, the coffee culture represents an important component of the agricultural chain in Brazil. The growing values of commercialization, planting areas, and crop productivity require the acquisition of quality seedlings, which must receive adequate nutritional support through efficient fertilizers. Slow and controlled-release fertilizers, such as organominerals, gain prominence when it comes to increasing efficiency in the use of phosphorus, as well as plant growth-promoting bacteria (PGPB) with phosphate solubilizing characteristics. This study aimed to evaluate the effect of different sources of mineral and organomineral fertilizers, inoculated and non-inoculated with PGPB on the quality parameters of coffee seedlings. In general, the P sources used in the experiment positively interfered with the development of coffee seedlings. This proves that there is a need for nutritional supplementation for the good development of the seedlings. Among the sources used, the organomineral in granulated form showed better performance in coffee seedlings' growth and physiological parameters, proving to be a viable alternative to commonly used fertilizers. The addition of PGPB showed a significant advantage for seedling quality variables.
