Relationship Pacing in Adolescents Before and After a Relationship Education Course: Considering the Influence of Demographics, Relationship History and Well-Being

Adolescence is a time when many individuals begin to participate in dating. Adolescent romantic relationships can have benefits for youth but can also be harmful if they do not have the information and skills needed to form and maintain healthy relationships. This study analyzed survey data from a youth relationship education program entitled the Premarital and Interpersonal Choices and Knowledge (PICK) program from a group of 14,468 adolescents. This study examined how different demographics were associated with decision making in relationships, referred to as relationship pacing in this study, before participating in the course. Demographic factors that were included were race, gender, family structure, number of times moved and if the individuals felt their basic needs were being met. Additional factors such as the well-being of students and if they had ever dated were also examined to test if those factors influenced their relationship pacing. This study also examined the students’ improvements in their reports of decision making in relationships after participating in the course and whether their demographics influenced how they benefited from the class. Again, their well-being and whether they had ever dated were also considered as potential moderators. Findings indicated that certain demographics did report healthier decision making prior to participating in the course and that their reports depended on their well-being and whether they had ever dated. Findings also indicated that some demographics improved in decision making after participating in the course more than others. Again, the degree of these improvements depended on factors such as their well-being and whether they had ever dated. These findings indicate that many factors influence how youth pace their relationships and that some youth may benefit from relationship education more than others. Suggestions are given for future research to continue to understand for whom relationship education is the most beneficial and for practitioners to be aware of these differences in participants when presenting relationship education courses

Caring for a Family Member During Stressful Times: Considerations for Maintaining Mental Health

Caring for a family member can take many forms. Whether you are caring for your mother with dementia or your son with a disability, caregiving for a family member can be very rewarding yet very stressful. As a family caregiver, it is likely that your stress has increased even more due to the COVID-19 pandemic. Now more than ever, you might find it helpful to “care for the caregiver.” This fact sheet will help you identify your own stress, explore strategies to manage this stress, and then use additional resources for further support and assistance

Mental health supportive services during COVID-19: Proposing an online, self-guided Acceptance and Commitment Therapy program for parents in the disability community

Parents of Children with Intellectual and Developmental Disabilities (I/DD) often experience stress, and the COVID-19 pandemic has likely increased their stress. In the current paper, we describe four things. First, we describe how mental telehealth treatments can effectively decrease parent stress, including programs that target behavior training and those that provide therapy. Teleheath programs are delivered by phone, computer, or fully online. Second, we describe challenges of these programs and explain how online, self-guided programs may help address these challenges. Third, we explain our online, self-guided program based in Acceptance and Commitment Therapy (ACT). ACT is a specific type of therapy that helps people notice their moods and their thoughts to help manage stress. Finally, we conclude by proposing a call for collaboration to improve and expand our online, self-guided, ACT program

Precise age of Bangiomorpha pubescens dates the origin of eukaryotic photosynthesis

Although the geological record indicates that eukaryotes evolved by 1.9–1.4 Ga, their early evolution is poorly resolved taxonomically and chronologically. The fossil red alga Bangiomorpha pubescens is the only recognized crown-group eukaryote older than ca. 0.8 Ga and marks the earliest known expression of extant forms of multicellularity and eukaryotic photosynthesis. Because it postdates the divergence between the red and green algae and the prior endosymbiotic event that gave rise to the chloroplast, B. pubescens is uniquely important for calibrating eukaryotic evolution. However, molecular clock estimates for the divergence between the red and green algae are highly variable, and some analyses estimate this split to be younger than the widely inferred but poorly constrained first appearance age of 1.2 Ga for B. pubescens. As a result, many molecular clock studies reject this fossil ex post facto. Here we present new Re-Os isotopic ages from sedimentary rocks that stratigraphically bracket the occurrence of B. pubescens in the Bylot Supergroup of Baffin Island and revise its first appearance to 1.047 +0.013/–0.017 Ga. This date is 150 m.y. younger than commonly held interpretations and permits more precise estimates of early eukaryotic evolution. Using cross-calibrated molecular clock analyses with the new fossil age, we calculate that photosynthesis within the Eukarya emerged ca. 1.25 Ga. This date for primary plastid endosymbiosis serves as a benchmark for interpreting the fossil record of early eukaryotes and evaluating their role in the Proterozoic biosphere

Ochre use at Olieboomspoort, South Africa: insights into specular hematite use and collection during the Middle Stone Age

Open access funding provided by University of the Witwatersrand. This paper is based on MSc research undertaken by JC funded by the NRF. Excavations and sourcing were generously funded by GENUS (DST/NRF Center of Excellence in Palaeosciences). PdlP has a Ramón y Cajal Research contract (RYC2020-029506-I) at the Universidad de Granada (Spain) funded by European social fund and the Agencia Estatal de Investigación (Spain). The prospection survey for raw material procurement analysis was made possible thanks to a Poroulis grant facilitated by Cambridge University to PdlP. AV was supported by the personal grant #2021.00782.CEECIND/CP1672/CT0005 of the Portuguese Foundation for Science and Technology (FCT).Recent excavations at Olieboomspoort (OBP) in the Waterberg Mountains of South Africa confirmed previous research at the site that highlighted an abundance of ochre in the Middle Stone Age (MSA) deposits. Here, we report on the results of an analysis of the ochre from the MSA deposits excavated in 2018–2019. Fossilised equid teeth from these deposits were recently dated to approximately 150 ka, an early date for such a sizeable ochre assemblage in southern Africa. Calcium carbonate concretions were removed from ochre pieces using hydrochloric acid. Macro- and microscopic analyses were undertaken to identify raw material types and to investigate utilisation strategies. There are 438 pieces in the assemblage and only 14 of them show definite use-traces. The predominant raw material is a micaceous, hard specular hematite, which is rare at MSA sites elsewhere in southern Africa. A preliminary investigation into the geological nature of the ochreous materials in the archaeological sample and those available in the area was performed using semi-quantitative portable X-ray fluorescence (pXRF), XRF, and inductively coupled plasma mass spectrometry (ICP-MS). Together with site formation processes, we suggest possible, primarily local sources of the ochre found in the deposits. The data do not support previous suggestions that OBP was used as an ochre caching site that may have formed part of an exchange network during the MSA. Instead, the local abundance of nodules of specular hematite within the Waterberg sandstone, the limited number of used pieces in the assemblage, and the stratigraphic context indicate a more natural, less anthropogenic explanation for the abundance of ochre at the site.South African Heritage Resources AgencyUniversity of the Witwatersrand, JohannesburgGenus RYC2020-029506-INational Research Foundation NRFFundação para a Ciência e a Tecnologia FCTEuropean Social Fund Plus ESFUniversidad de Granada UGRAgencia Estatal de Investigación 2021.00782 AE
