The sovereignty cartel: what citizenship for sale schemes tell us about the nature of sovereignty
What makes sovereignty possible? Drawing on the example of citizenship for sale programmes, J. Samuel Barkin argues that sovereignty is built on state collusion – states work together to privilege sovereignty in global politics because they benefit from its exclusivity
Brief 8: International Fisheries Governance that Works: The Case for a Global Fisheries Organization
International fisheries are being overexploited, and the current institutional structure in place to manage them is not working effectively. Presently, two sets of intergovernmental institutions oversee global fishing. The first comprises roughly three dozen regional fisheries management organizations (RFMOs), approximately 19 of which are charged with regulating fishing in the areas they oversee. The second set consists of global organizations that touch on but do not directly regulate fisheries issues, such as the United Nations Food and Agriculture Organization (FAO), the World Trade Organization (WTO), the World Bank, and the International Maritime Organization (IMO). This management patchwork is inadequate to the task, and needs to be supplemented by a new global fisheries organization. Such an organization would most usefully serve three core functions: Coordinating the various existing institutional participants in international fisheries governance; Addressing the crisis of overcapitalization and overcapacity in the fishing industry driven by widespread government subsidies; Overseeing a system of international individual transferable quotas (ITQs).
This policy brief outlines the nature of the problem and discusses these three functions in greater depth
Relative equilibria in the unrestricted problem of a sphere and symmetric rigid body
We consider the unrestricted problem of two mutually attracting rigid bodies,
an uniform sphere (or a point mass) and an axially symmetric body. We present a
global, geometric approach for finding all relative equilibria (stationary
solutions) in this model, which was already studied by Kinoshita (1970). We
extend and generalize his results, showing that the equilibria solutions may be
found by solving at most two non-linear, algebraic equations, assuming that the
potential function of the symmetric rigid body is known explicitly. We
demonstrate that there are three classes of the relative equilibria, which we
call "cylindrical", "inclined co-planar", and "conic" precessions,
respectively. Moreover, we also show that in the case of conic precession,
although the relative orbit is circular, the point-mass and the mass center of
the body move in different parallel planes. This solution has been yet not
known in the literature.Comment: The manuscript with 10 pages, 5 figures; accepted to the Monthly

The effect of counseling with a skills training approach on maternal functioning: a randomized controlled clinical trial
BACKGROUND: The role of the mother can be deeply satisfying, but it is associated with many challenges including challenges during the postpartum period that may impede the optimal development of the infant. Therefore, the aim of the present study was to investigate the effects of counseling using the Skills Training Approach (STA) on postpartum maternal functioning.
METHODS: This randomized controlled trial was performed on 68 postpartum women who referred to health centers of Tabriz-Iran in 2019. Participants were assigned to one of two groups - either counseling or control through the block randomization method. The intervention group received four counseling sessions using the Skills Training Approach (STA). Before and two weeks after the completion of the intervention, the Barkin Index of Maternal Functionning (BIMF) was completed by the participants. The independent t-test and ANCOVA (Analysis of Covariance) was used to analyze the data.
RESULTS: There was no statistically significant difference between the two groups in terms of sociodemographic characteristics and the baseline scores of the BIMF and its domains (p\u2009>\u20090.05). Before the intervention, the mean (SD) total score of the BIMF in the intervention group was 73.1 (8.5) and in the control group, it was 71.6 (4.8). Post-intervention, the mean (SD) of the total score of the BIMF in the intervention group was 95.8 (11.8) and in the control group, it was 70.3 (4.5). Based on the ANCOVA test and after adjusting the baseline score, the mean total score of the BIMF was significantly higher in the intervention group than in the control group (Mean Difference (MD): 22.9; 95% CI: 18.2 to 27.6; p\u2009<\u20090.001). The post-intervention scores of all domains of the BIMF including self-care (MD: 3.8), infant care (MD: 2.0), mother-child interaction (MD: 4.8), psychological wellbeing (MD: 8.4), social support (MD: 4.0), management (MD: 6.8), and adjustment to new motherhood (MD: 3.2) were significantly higher in the intervention group compared to the control group (P\u2009<\u20090.001).
CONCLUSION: In this study, counseling, using STA, was effective in improving maternal functioning in all of the domains. This intervention, aimed at skill-building, should be strongly considered where improved postpartum functioning is the goal

Identifying Bedrest Using Waist-worn Triaxial Accelerometers in Preschool Children
Purpose
To adapt and validate a previously developed decision tree for youth to identify bedrest for use in preschool children. Methods
Parents of healthy preschool (3-6-year-old) children (n = 610; 294 males) were asked to help them to wear an accelerometer for 7 to 10 days and 24 hours/day on their waist. Children with ≥3 nights of valid recordings were randomly allocated to the development (n = 200) and validation (n = 200) groups. Wear periods from accelerometer recordings were identified minute-by-minute as bedrest or wake using visual identification by two independent raters. To automate visual identification, chosen decision tree (DT) parameters (block length, threshold, bedrest-start trigger, and bedrest-end trigger) were optimized in the development group using a Nelder-Mead simplex optimization method, which maximized the accuracy of DT-identified bedrest in 1-min epochs against synchronized visually identified bedrest (n = 4,730,734). DT\u27s performance with optimized parameters was compared with the visual identification, commonly used Sadeh’s sleep detection algorithm, DT for youth (10-18-years-old), and parental survey of sleep duration in the validation group. Results
On average, children wore an accelerometer for 8.3 days and 20.8 hours/day. Comparing the DT-identified bedrest with visual identification in the validation group yielded sensitivity = 0.941, specificity = 0.974, and accuracy = 0.956. The optimal block length was 36 min, the threshold 230 counts/min, the bedrest-start trigger 305 counts/min, and the bedrest-end trigger 1,129 counts/min. In the validation group, DT identified bedrest with greater accuracy than Sadeh’s algorithm (0.956 and 0.902) and DT for youth (0.956 and 0.861) (both P\u3c0.001). Both DT (564±77 min/day) and Sadeh’s algorithm (604±80 min/day) identified significantly less bedrest/sleep than parental survey (650±81 min/day) (both P\u3c0.001). Conclusions
The DT-based algorithm initially developed for youth was adapted for preschool children to identify time spent in bedrest with high accuracy. The DT is available as a package for the R open-source software environment (“PhysActBedRest”)
Primary Health Care: Potential Home for Family-Focused Preventive Interventions
Family-focused prevention programs have been shown to effectively reduce a range of negative behavioral health outcomes but have had limited reach. Three key barriers must be overcome to expand the reach of family-focused prevention programs and thereby achieve a significant public health impact. These barriers are (1) current social norms and perceptions of parenting programs; (2) concerns about the expertise and legitimacy of sponsoring organizations to offer parenting advice; and (3) a paucity of stable, sustainable funding mechanisms. Primary healthcare settings are well positioned to overcome these barriers. Recent changes within health care make primary care settings an increasingly favorable home for family-focused prevention and suggest possibilities for sustainable funding of family-focused prevention programs. This paper discusses the existing advantages of primary care settings and lays out a plan to move toward realizing the potential public health impact of family-focused prevention through widespread implementation in primary healthcare settings
Racial and Ethnic Differences in Injury Prevention Behaviors Among Caregivers of Infants
African American and Latino children experience higher rates of traumatic injury and mortality, but the extent to which parents of different races and ethnicities disparately enact injury prevention behaviors has not been fully characterized. The objective of this study is to evaluate the association between caregiver race/ethnicity and adherence to injury prevention recommendations
