Mental Health And The Role Of The States
Researchers from the State Health Care Spending Project -- a collaboration between The Pew Charitable Trusts and the John D. and Catherine T. MacArthur Foundation -- sought to better understand the country's mental health challenges and, in particular, the states' role in addressing them. The project found that:In 2013, approximately 44 million adults -- 18.5 percent of the population 18 and older -- were classified as having a mental illness. Of these, 10 million had a serious mental illness. The rate of serious mental illness varied from state to state.In 2009, the most recent year for which national mental health data are available, 22 billion (15 percent) in 2009. This total does not include state and local Medicaid expenditures. Counting those contributions brings total state and local spending up to $35.5 billion (24 percent).This report is intended to help federal, state, and local policymakers working to address the country's mental health challenges to better understand their prevalence, treatment, and funding trends
Time to Get in the Game: Opportunities for More Involvement in Sport-Related Concussion Management
Many college athletes who have a sport-related concussion experience changes in cognitive-communication abilities. Unfortunately, nearly half of all sport-related concussions go unreported. Information on why collegiate athletes report or conceal their symptoms is important for improving reporting rates and increasing athletes’ access to services for cognitive-communication impairments. This study examined whether changes in cognitive-communication abilities affected college athlete’s intentions to report a sport-related concussion. Findings showed that approximately two-thirds of the college student-athletes who participated in the research were unlikely to report that they had a sport-related head injury. The study found that participants’ concerns for cognitive-communication deficits differentiated student-athletes who were more likely to report an injury from those who were less likely. This study has important clinical implications for increasing awareness and knowledge about the sequelae of sport-related concussion and the valuable role that rehabilitation specialists, such as speech-language pathologists (SLPs), can play in concussion management and prevention
Nighttime notifications and compulsivity illuminate the link between emerging adults’ cellphone use and sleep-related problems
Although higher levels of cellphone use have been correlated with sleep problems, few studies have investigated specific qualities of cellphone use that may account for this relationship. Recently, significant associations among nighttime cellphone use, compulsive orientation toward cellphone use, and multiple characteristics of compromised sleep were found in a sample of undergraduate students enrolled at a small liberal arts college (Murdock, Horissian, & Crichlow-Ball, 2016). The current study expands upon these findings. Data were collected from 2 samples of undergraduates: 273 students enrolled at a midsized state university and 152 self-identified students recruited through Mechanical Turk. Hierarchical regression analyses were conducted to test the hypotheses that nighttime cellphone notifications and qualities of compulsive cellphone use would predict sleep problems and daytime sleepiness, even after taking into account the overall frequency of cellphone use. Full support for hypotheses was found for both domains of sleep-related functioning in both samples. Findings suggest that contextual aspects of cellphone use, such as its timing and compulsivity, may be more important to emerging adults’ sleep than aspects of cellphone use such as the number of texts or time spent on calls. Sleep promotion programs for emerging adults should target specific cellphone use qualities—that is, the when, where, and how of cellphone use—to promote behavior change and improved sleep
Repressive Interactions Between Transcription Factors Separate Different Embryonic Ectodermal Domains.
The embryonic ectoderm is composed of four domains: neural plate, neural crest, pre-placodal region (PPR) and epidermis. Their formation is initiated during early gastrulation by dorsal-ventral and anterior-posterior gradients of signaling factors that first divide the embryonic ectoderm into neural and non-neural domains. Next, the neural crest and PPR domains arise, eithe

Relativistic Landau resonances
The possible interactions between plasma waves and relativistic charged particles are considered. An electromagnetic perturbation in the plasma is formulated as an elliptically polarized wave, and the collisionless plasma is described by a distribution in phase space, which is realized in cylindrical coordinates. The linearized Vlasov equation is solved in the semi-relativistic limit, to obtain the distribution function in the rest frame of the observer. The perturbed currents supported by the ionized medium are then calculated, so that an expression can be written for the total amount of energy available for transfer through the Landau mechanism. It is found that only certain modes of the perturbed current are available for this energy transfer. The final expressions are presented in terms of Stokes parameters, and applied to the special cases of a thermal as well as a nonthermal plasma. The thermal plasma is described by a Maxwellian distribution, while two nonthermal distributions are considered: the kappa distribution and a generalized Weibull distribution
Genetic control of root architectural plasticity in maize
© 2020 The Author(s) 2020. Published by Oxford University Press on behalf of the Society for Experimental Biology. Root phenotypes regulate soil resource acquisition; however, their genetic control and phenotypic plasticity are poorly understood. We hypothesized that the responses of root architectural phenes to water deficit (stress plasticity) and different environments (environmental plasticity) are under genetic control and that these loci are distinct. Root architectural phenes were phenotyped in the field using a large maize association panel with and without water deficit stress for three seasons in Arizona and without water deficit stress for four seasons in South Africa. All root phenes were plastic and varied in their plastic response. We identified candidate genes associated with stress and environmental plasticity and candidate genes associated with phenes in well-watered conditions in South Africa and in well-watered and water-stress conditions in Arizona. Few candidate genes for plasticity overlapped with those for phenes expressed under each condition. Our results suggest that phenotypic plasticity is highly quantitative, and plasticity loci are distinct from loci that control phene expression in stress and non-stress, which poses a challenge for breeding programs. To make these loci more accessible to the wider research community, we developed a public online resource that will allow for further experimental validation towards understanding the genetic control underlying phenotypic plasticity
An analysis of the main project organizational structures: advantages, disadvantages, and factors affecting their selection
Generally, we can define project organizational structures as organizational forms, based on temporary teams that are created to perform particular tasks and disappear after achieving the established goals. Whereas simple projects may require a limited number of steps and specializations, complex projects may be composed of plentiful of steps and require diverse and different specializations. As the project increases in size and design more units and specializations are added to the organizational structure contributing to both more vertical and horizontal organizational differentiation. Thus, when designing a project organizational structure the following questions must be answered: How many different specializations are included in the design of the project? How are the interrelatedness between the different elements of the project and between the different specializations? How many different activities are to be managed? In this paper, we analyse the three generic project organizational structures that are presented in the extant literature; functional, pure project, and matrix, together with their advantages and disadvantages. Furthermore, the most important factors that should be considered when designing a proper organizational structure are also analysed
