Randomized Controlled Trial
Physical inactivity constitutes a major health problem in many Western societies affecting a variety of social groups. As these groups often differ in responsivity to physical inactivity messages, the strategy of message targeting, i.e. the customization of messages toward shared characteristics of a social group provides a useful framework for designing effective communication. Whereas focusing on health consequences of physical inactivity might prove useful for some social groups, it might be more effective to emphasize its social or financial consequences for others. The current examination compares the effects of three types of consequence framing (health consequences vs. social consequences vs. financial consequences of physical inactivity) on health-related perceptions and intentions for different population subgroups. An experiment with a one-factorial between subjects design based on a quota sample was conducted. 348 respondents differing in terms of age, sex, and formal education were randomly assigned to one of the three experimental conditions and read an accordingly manipulated newspaper article. Findings show that financial and social consequence frames were more effective than health consequence frames. Both frames positively influenced behavioral intentions through perceptions of susceptibility. These effects were largely independent of sociodemographic variables, although sex and education emerged as moderators in some cases.

An analysis is presented of the numbers of medical students in South African medical schools and of medical graduates produced annually. The data are analyzed according to ethnic groups. It is shown that gross discrepancies exist, and that black (African) and "Colored" sectors of the population are seriously underrepresented. This pattern is found for the total number of medical students; the ratio of number of medical students in each ethnic group to the total population of that group; the number of medical schools to which blacks may, in terms of the government's apartheid policy, be freely admitted; the absolute numbers of medical graduates drawn from each ethnic group and the percentage of the total number of medical practitioners stemming from each population group; and the ratio of the numbers of medical graduates in each ethnic group to the total population of that group. No matter which yardstick is employed, marked discrepancies are apparent. It is maintained that the separate and inferior schooling system for blacks, under the apartheid policy, is not providing suitably qualified medical student material from the African and "Colored" population groups; and that the State (under which all South African medical schools fall) has not permitted existing medical school facilities to be freely opened for the medical training of blacks, nor has it made available sufficient facilities for the medical training of blacks. It is concluded that the apartheid policy, with its many ramifications at primary, secondary, and tertiary educational levels, has constituted the most serious setback to medical education in southern Africa. It has left medical education in southern Africa over 30 years behind a point where it could and should have been.

Linguistic and cultural evidence suggest that Madagascar was the final point of two major dispersals of Austronesian- and Bantu-speaking populations. Today, the Mikea are described as the last-known Malagasy population reported to be still practicing a hunter-gatherer lifestyle. It is unclear, however, whether the Mikea descend from a remnant population that existed before the arrival of Austronesian and Bantu agriculturalists or whether it is only their lifestyle that separates them from the other contemporary populations of South Madagascar. To address these questions we have performed a genome-wide analysis of >700,000 SNP markers on 21 Mikea, 24 Vezo, and 24 Temoro individuals, together with 50 individuals from Bajo and Lebbo populations from Indonesia. Our analyses of these data in the context of data available from other Southeast Asian and African populations reveal that all three Malagasy populations are derived from the same admixture event involving Austronesian and Bantu sources. In contrast to the fact that most of the vocabulary of the Malagasy speakers is derived from the Barito group of the Austronesian language family, we observe that only one-third of their genetic ancestry is related to the populations of the Java-Kalimantan-Sulawesi area. Because no additional ancestry components distinctive for the Mikea were found, it is likely that they have adopted their hunter-gatherer way of life through cultural reversion, and selection signals suggest a genetic adaptation to their new lifestyle.

AIM
To compare the population group from the Šopot graveyard with population groups from traditional Croatian medieval graveyards by using anthropological, craniometrics, and mitochondrial (mtDNA) analysis and to examine if the cultural differences between population groups reflect biological differences.
METHODS
We determined sex, age at death, pathological, and traumatic changes of skeletal remains from the Šopot graveyard and compared them with a cumulative medieval sample from the same region. We also performed principal component analysis to compare skeletal remains from Šopot with those from Ostrovica and other Central European samples according to 8 cranial measurements. Finally, we compared 46 skeletons from Šopot with medieval (Ostrovica) and contemporary populations using mDNA haplogroup profiling.
RESULTS
The remains from Šopot were similar to the cumulative sample in lifestyle and quality of life markers. Principal component analysis showed that they were closely related to Eastern Adriatic coast sites (including Ostrovica and Šopot) in terms of cranial morphology, indicating similar biological makeup. According to mDNA testing, Šopot population showed no significant differences in the haplogroup prevalence from either medieval or contemporary populations.
CONCLUSION
This study shows that the Šopot population does not significantly differ from other medieval populations from this area. Besides similar quality of life markers, these populations also had similar biological markers. Substantial archeological differences can therefore be attributed to apparent cultural influences, which in this case do not reflect biological differences.

A total of 2443 male individuals, previously typed for the 13 CODIS STR loci, distributed across the five North American population groups African American, Asian, Caucasian, Hispanic, and Native American were typed for the Y-STR loci DYS19, DYS385a/b, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the PowerPlex Y System. All population samples were highly polymorphic for the 12 Y-STR loci with the marker DYS385a/b being the most polymorphic across all sample populations. The Native American population groups demonstrated the lowest genetic diversity, most notably at the DYS393 and DYS437 loci. Almost all of the 12-locus haplotypes observed in the sample populations were represented only once in the database. Haplotype diversities were greater than 99.6% for the African Americans, Caucasians, Hispanics, and Asians. The Native Americans had the lowest haplotype diversities (Apaches, 97.0%; Navajo, 98.1%). Population substructure effects were greater for Y-haplotypes, compared with that for the autosomal loci. For the apportionment of variance for the 12 Y-STRs, the within sample population variation was the largest component (>98% for each major population group and approximately 97% in Native Americans), and the variance component contributed by the major population groups was less than the individual component, but much greater than among sample populations within a major group (11.79% versus 1.02% for African Americans/Caucasians/Hispanics and 15.35% versus 1.25% for all five major populations). When each major population is analyzed individually, the R(ST) values were low but showed significant among group heterogeneity. In 692 confirmed father-son pairs, 14 mutation events were observed with the average rate of 1.57x10(-3)/locus/generation (a 95% confidence bound of 0.83x10(-3) to 2.69x10(-3)). Since the Y-STR loci reside on the non-recombining region of the Y chromosome, the counting method is one approach suggested for conveying an estimate of the rarity of the Y-haplotype. Because the Y-STR loci are not all in disequilibrium to the same extent, the counting method is a very conservative approach. The data also support that autosomal STR frequencies can be multiplied by the upper bound frequency estimate of a Y-haplotype in the individual population group or those pooled into major population groups (i.e., Caucasian, African American, Hispanic, and Asian). These analyses support use of the haplotype population data for estimating Y-STR profile frequencies for populations residing in North America.

Popular academic ideas linking physiological adaptations to social behaviors are spreading disconcertingly into wider societal contexts. In this article, we note our skepticism with one particularly popular—in our view, problematic—supposed causal correlation between neocortex size and social group size. The resulting Dunbar's Number, as it has come to be called, has been statistically tested against observed group size in different primate species. Although there may be reason to doubt the Dunbar's Number hypothesis among nonhuman primate species, we restrict ourselves here to the application of such an explanatory hypothesis to human, culture-manipulating populations. Human information process management, we argue, cannot be understood as a simple product of brain physiology. Cross-cultural comparison of not only group size but also relationship-reckoning systems like kinship terminologies suggests that although neocortices are undoubtedly crucial to human behavior, they cannot be given such primacy in explaining complex group composition, formation, or management.

BACKGROUND
American Indian/Alaskan Native (AI/AN) communities are second only to White Americans in mortality from opioid use disorder (OUD), while the smallest racial/ethnic minority population group in the USA. Those in rural communities experience significant health care disparities, including poorer treatment access for substance use disorder. This systematic scoping review aimed to trend the emerging evidence on opioid use disorder (OUD) management among rural AI/AN communities as well as workforce training needs.
METHOD
We searched the Medline, Embase, PsycInfo, SSCI, and Digital theses databases for empirical study publications on OUD management among AI/AN rural communities across the continuum of prevention, treatment and care. Eight studies met the following criteria: (a) focused on OUD; (b) sampled rural AI/AN members; (c) investigated prevention, treatment and/or care perspectives and/or practices or health provider preparation; and (d) published during the period 2009-2020. Included studies met the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) quality control standards.
FINDINGS
Six of eight of the studies (75%) were surveys with community members and other stakeholders on OUD management within rural AI/AN communities rather than active interventions within this population. Moreover, five of eight of the studies (63%) reported a preference for culturally grounded health and wellness interventions with rural AI/AN, involving families, and community interventionists, utilizing community reinforcement approaches. Three of eight studies (37.5%) reported need for the cultural adaption of medication-assisted treatments (MAT) and use of culturally informed recovery care approaches. One of eight studies (12.5%) proposed to use culturally adapted contingency management behavioral approaches for OUD treatment and recovery care.
CONCLUSION
The evidence is trending to endorse culturally adapted OUD management with rural AI/AN communities, prioritizing prevention education, and use of MAT with cultural adaptation and whole person approaches to sustainable recovery care. Mental health care should be a part OUD prevention, treatment and recovery care in rural AI/AN rural communities.

The objectives in this statement are to characterize and explain the patterns of change in stratification and mobility in Egypt, over the last half century, by placing them within conceptual, explanatory, and historical contexts. First, literature relevant to the primary concepts of "class" and "status", is reviewed. Second, four institutions whose influence is fundamental in shaping these patterns are identified to form an explanatory context: family, polity, economy, and education. And third, an historical account is presented to demonstrate the interplay of these institutions and their consequences for stratification and mobility. For this, four periods are identified that are marked by change in the dominance of institutions and their corresponding influence on stratification and mobility. In addition to data available in relevant literature, this analysis utilizes primary data generated through a national probability household survey.

Developing a forensic DNA database on a population that consists of local ethnic groups separated by physical and cultural barriers is questionable as it can be genetically subdivided. On the other side, small sizes of ethnic groups, especially in alpine regions where they are sub-structured further into small villages, prevent collecting a large sample from each ethnic group. For such situations, we suggest to obtain both a total population database on allele frequencies across ethnic groups and a list of theta-values between the groups and the total data. We have genotyped 558 individuals from the native population of South Siberia, consisting of nine ethnic groups, at 17 autosomal STR loci of the kit packages AmpFlSTR SGM Plus i, Cyrillic AmpFlSTR Profiler Plus. The groups differentiate from each other with average theta-values of around 1.1%, and some reach up to three to four percent at certain loci. There exists between-village differentiation as well. Therefore, a database for the population of South Siberia is composed of data on allele frequencies in the pool of ethnic groups and data on theta-values that indicate variation in allele frequencies across the groups. Comparison to additional data on northeastern Asia (the Chukchi and Koryak) shows that differentiation in allele frequencies among small groups that are separated by large geographic distance can be even greater. In contrast, populations of Russians that live in large cities of the European part of Russia are homogeneous in allele frequencies, despite large geographic distance between them, and thus can be described by a database on allele frequencies alone, without any specific information on theta-values.
