The Emerging Pattern of Geopolitics

Without ignoring the two wars that are currently taking place in Iraq and Afghanistan, the Strategic Studies Institute (SSI) sought to reframe the debate over security within a global context. Thus Mr. Rodman’s address sets contemporary security challenges to the United States within a framework of both an Islamist challenge rising from the Jihadi movement across the Muslim world that mostly finds its expression in terrorism and in the dynamics of the rise and decline of great powers.https://press.armywarcollege.edu/monographs/1359/thumbnail.jp

Stress-Related Psychopathology During the COVID-19 Pandemic

The COVID-19 pandemic has introduced widespread societal changes that have required ongoing adaptation. Unsurprisingly, stress-related psychopathology has increased during the pandemic, in both children and adults. We review these patterns through the lens of several leading conceptual models of the link between stress and psychopathology. Some of these models focus on characteristics of environmental stressors—including cumulative risk, specific stressor types, and stress sensitization approaches. Understanding the specific aspects of environmental stressors that are most likely to lead to psychopathology can shed light on who may be in most need of clinical intervention. Other models center on factors that can buffer against the onset of psychopathology following stress and the mechanisms through which stressors contribute to emergent psychopathology. These models highlight specific psychosocial processes that may be most usefully targeted by interventions to reduce stress-related psychopathology. We review evidence for each of these stress models in the context of other widescale community-level disruptions, like natural disasters and terrorist attacks, alongside emerging evidence for these stress pathways from the COVID-19 pandemic. We discuss clinical implications for developing interventions to reduce stress-related psychopathology during the pandemic, with a focus on brief, digital interventions that may be more accessible than traditional clinical services

Rural Breast Cancer Patients and Survivors Perspectives using Online Health Resources

Background: Breast cancer is the second most common cancer in women, with over 2.5 million breast cancer survivors in the United States. These patients, survivors and their loved ones use the Internet to find information about breast cancer, search for treatment options and connect with support groups. For women in medically underserved areas, especially rural areas, the Internet could be one of their only sources of information. Objective: The study investigates rural breast cancer patients’ and survivors’ motivations to seek online information, ability to use the Internet as a health information source, barriers to finding the information they seek, and the search strategy they use when seeking information online. Methods: This qualitative study used “think-aloud” interviews with rural breast cancer patients and survivors to examine the thought process used to select online breast cancer information. Data were analyzed using thematic analysis in NVivo 9. Results: Patients use Internet searches to corroborate provider recommendations and treatment plans. They preferred websites affiliated with nationally recognized cancer centers and breast cancer support organizations with few advertisements and comprehensive information. Conclusions: The importance of trust within the provider-patient relationship is a core theme. Although the provider is the preferred source of information, patients will use the Internet to verify provider recommendations. Implications for Practice: Rural breast cancer patients desire Internet search training. Nurses and breast cancer survivors would be effective trainers to increase patient online search information satisfaction and provide reliable resources for patients seeking accurate health

Stability study of a model for the Klein-Gordon equation in Kerr spacetime

The current early stage in the investigation of the stability of the Kerr metric is characterized by the study of appropriate model problems. Particularly interesting is the problem of the stability of the solutions of the Klein-Gordon equation, describing the propagation of a scalar field of mass $\mu$ in the background of a rotating black hole. Rigorous results proof the stability of the reduced, by separation in the azimuth angle in Boyer-Lindquist coordinates, field for sufficiently large masses. Some, but not all, numerical investigations find instability of the reduced field for rotational parameters $a$ extremely close to 1. Among others, the paper derives a model problem for the equation which supports the instability of the field down to $a/M \approx 0.97$.Comment: Updated version, after minor change

Future Dominance by Quaking Aspen Expected Following Short-Interval, Compounded Disturbance Interaction

The spatial overlap of multiple ecological disturbances in close succession has the capacity to alter trajectories of ecosystem recovery. Widespread bark beetle outbreaks and wildfire have affected many forests in western North America in the past two decades in areas of important habitat for native ungulates. Bark beetle outbreaks prior to fire may deplete seed supply of the host species, and differences in fire‐related regeneration strategies among species may shift the species composition and structure of the initial forest trajectory. Subsequent browsing of postfire tree regeneration by large ungulates, such as elk (Cervus canadensis), may limit the capacity for regeneration to grow above the browse zone to form the next forest canopy. Five stand‐replacing wildfires burned ~60,000 ha of subalpine forest that had previously been affected by severe ( \u3e90% mortality) outbreaks of spruce beetle (SB, Dendroctonus rufipennis) in Engelmann spruce (Picea engelmannii) in 2012–2013 in southwestern Colorado. Here we examine the drivers of variability in abundance of newly established conifer tree seedlings [spruce and subalpine fir (Abies lasiocarpa)] and resprouts of quaking aspen (Populus tremuloides) following the short‐interval sequence of SB outbreaks and wildfire (2–8 yr between SB outbreak and fire) at sites where we previously reconstructed severities of SB and fire. We then examine the implications of ungulate browsing for forest recovery. We found that abundances of postfire spruce seedling establishment decreased substantially in areas of severe SB outbreak. Prolific aspen resprouting in stands with live aspen prior to fire will favor an initial postfire forest trajectory dominated by aspen. However, preferential browsing of postfire aspen resprouts by ungulates will likely slow the rate of canopy recovery but browsing is unlikely to alter the species composition of the future forest canopy. Collectively, our results show that SB outbreak prior to fire increases the vulnerability of spruce–fir forests to shifts in forest type (conifer to aspen) and physiognomic community type (conifer forest to non‐forest). By identifying where compounded disturbance interactions are likely to limit recovery of forests or tree species, our findings are useful for developing adaptive management strategies in the context of warming climate and shifting disturbance regimes
