The work of Herbert Spencer was a crucial influence on the development of Peter Kropotkin's historical sociology. However, scholars have underestimated this relationship; either overlooking it entirely, or minimizing Kropotkin's attachment to Spencer with the aim of maintaining the utility of his political thought in the present. This article contests these interpretations by analyzing Kropotkin's reading of Spencer's epistemological, biological, and political ideas. It argues that Kropotkin was engaged in a critical dialogue with Spencer, incorporating many Spencerian principles in his own system, but also using this reading to articulate a distinctive anarchist politics...

The human ribcage expands and contracts during respiration as a result of the interaction between the morphology of the ribs, the costo-vertebral articulations and respiratory muscles. Variations in these factors are said to produce differences in the kinematics of the upper thorax and the lower thorax, but the extent and nature of any such differences and their functional implications have not yet been quantified. Applying geometric morphometrics we measured 402 three-dimensional (3D) landmarks and semilandmarks of 3D models built from computed tomographic scans of thoraces of 20 healthy adult subjects in maximal forced inspiration (FI) and expiration (FE)...

Tumor-specific genomic information has the potential to guide therapeutic strategies and revolutionize patient treatment. Currently, this approach is limited by an abundance of disease-associated mutants whose biological functions and impacts on therapeutic response are uncharacterized. To begin to address this limitation, we functionally characterized nearly all (99.84%) missense mutants of MAPK1/ERK2, an essential effector of oncogenic RAS and RAF. Using this approach, we discovered rare gain- and loss-of-function ERK2 mutants found in human tumors, revealing that, in the context of this assay, mutational frequency alone cannot identify all functionally impactful mutants...

Comorbidity of internalizing and externalizing problems and its risk and protective factors have not been well incorporated into developmental research, especially among racial minority youth from high-poverty neighborhoods. The present study identified a latent comorbid factor as well as specific factors underlying internalizing and externalizing problems among 592 African American adolescents living in economically disadvantaged neighborhoods (291 male; M age = 15.9 years, SD = 1.43 years). Stressful life events and racial discrimination were associated with higher comorbid problems, whereas stressful life events and exposure to violence were associated with higher specific externalizing problems...

PURPOSE: To explore possible effects of tongue piercing on perceived speech quality. METHODS: Using a quasi-experimental design, we analyzed the effect of tongue piercing on speech in a perception experiment. Samples of spontaneous speech and read speech were recorded from 20 long-term pierced and 20 non-pierced individuals (10 males, 10 females each). The individuals having a tongue piercing were recorded with attached and removed piercing. The audio samples were blindly rated by 26 female and 20 male laypersons and by 5 female speech-language pathologists with regard to perceived speech quality along 5 dimensions: speech clarity, speech rate, prosody, rhythm and fluency...

Disordered awareness of memory loss (i.e., anosognosia) is a frequent and clinically relevant symptom of Alzheimer's disease (AD). The metacognitive errors which characterize anosognosia in AD, however, have not been fully articulated. The current study examined metamemory performance as a function of clinically defined awareness groups using different task conditions to examine the extent to which specific metacognitive deficits (i.e., detecting, integrating, or being explicitly aware of errors) contribute to anosognosia in AD (n = 49)...

INTRODUCTION: Single-incision laparoscopic colectomy is technically limited because of such factors as instrument crowding, in-line viewing, and insufficient countertraction. In particular, it is technically difficult to cut the distal rectum from the umbilicus using an articulating linear stapler in single-incision laparoscopic anterior resection. TECHNIQUE: After treating the mesorectum, the 5-mm trocar is replaced with a 12-mm trocar. The cartridge of the curved stapler is mounted while the shaft of the stapler is inserted into the 12-mm port extracorporeally...

The ecological niche and mate preferences have independently been shown to be important for the process of speciation. Here we articulate a novel mechanism by which ecological niche use and mate preference can be linked to promote speciation. The degree to which individual niches are narrow and clustered affects the strength of divergent natural selection and population splitting. Similarly, the degree to which individual mate preferences are narrow and clustered affects the strength of divergent sexual selection and assortative mating between diverging forms...

The Future of Home Health project sought to support transformation of home health and home-based care to meet the needs of patients in the evolving U.S. health care system. Interviews with key thought leaders and stakeholders resulted in key themes about the future of home health care. By synthesizing this qualitative research, a literature review, case studies, and the themes from a 2014 Institute of Medicine and National Research Council workshop on "The Future of Home Health Care," the authors articulate a vision for home-based care and recommend a bold framework for the Medicare-certified home health agency of the future...

BACKGROUND: Transfer of a flexor hallucis longus (FHL) tendon can not only reconstruct the Achilles tendon but also provide ischemic tendinous tissues with a rich blood supply to enhance wound healing. This retrospective study aims to investigate clinical outcomes in patients who underwent repair of Kuwada grade IV chronic Achilles tendon rupture with long hallucis longus tendons harvested using a minimally invasive technique. MATERIALS AND METHODS: 35 patients who were treated for Kuwada grade IV Achilles tendon injuries from July 2006 to June 2011 were included in this retrospective study...

This paper addresses the rapid pace of change in the technologies that support digital interventions; the complexity of the health problems they aim to address; and the adaptation of scientific methods to accommodate the volume, velocity, and variety of data and interventions possible from these technologies. Information, communication, and computing technologies are now part of every societal domain and support essentially every facet of human activity. Ubiquitous computing, a vision articulated fewer than 30 years ago, has now arrived...

Patient- and family-centered care is hailed as a hallmark of high-quality pediatric care. This partnership between patients, families and their healthcare providers is central to caring for children with chronic kidney disease (CKD), given the long-term and profound impact of the disease and its treatment on the development and quality of life of these children. This paradigm hinges on a comprehensive and detailed understanding of the needs, beliefs and values of children with CKD and their families. However, their perspectives may remain undisclosed during time-limited clinical consultations and because of beliefs that if they did disclose their concerns, their care would be jeopardized...

In this article we introduce family medicine educators to storytelling as an important teaching tool. We describe how stories are a critical part of the work of family physicians. We review the rationales for family medicine educators to become skilled storytellers. We present the components of effective stories, proposing two different perspectives on how to imagine, construct, and present them. We provide a list of resources for getting started in storytelling and offer two personal vignettes that articulate the importance of storytelling in the authors' respective professional developments...

Self-inflicted injury (SII) is a continuum of intentionally self-destructive behaviors, including nonsuicidal self-injuries, suicide attempts, and death by suicide. These behaviors are among the most pressing yet perplexing clinical problems, affecting males and females of every race, ethnicity, culture, socioeconomic status, and nearly every age. The complexity of these behaviors has spurred an immense literature documenting risk and vulnerability factors ranging from individual to societal levels of analysis...

BACKGROUND: Cells of the vascular system release spherical vesicles, called microparticles, in the size range of 0.1-1μm induced by a variety of stress factors resulting in variable concentrations between health and disease. Furthermore, microparticles have intercellular communication/signaling properties and interfere with inflammation and coagulation pathways. Today's most used analytical technology for mecroparticle characterization, flow cytometry, is lacking sensitivity and specificity, which might have led to the publication of contradicting results in the past...

BACKGROUND: Severe hip osteoarthritis is known to lead to secondary osteoarthritis of the knee joint. It is not clear whether contracture or a leg length discrepancy is more important in determining the knee alignment. METHODS: In this study, 48 hips in 48 patients with a unilateral completely dislocated hip (Crowe IV) were recruited. The patients were divided into two groups (Crowe IVa and IVb). The Crowe IVa group had completely dislocation with psudo-articulation, and the Crowe IVb group had completely dislocation without psudo-articulation...

The history of government action on HIV/AIDS has much to teach us about the dynamics and possibilities of US public health policy, but it has been insufficiently studied by social scientists of the epidemic. This article draws on a large set of original interviews with policy makers, thousands of news articles, and extensive documentation to reconstruct the history of three areas of debate and decision making about HIV prevention since 1990: needle exchange, HIV testing, and sex education for at-risk groups...

Biological tissues at articulating surfaces, such as articular cartilage, typically have remarkable low-friction properties that limit tissue shear during movement. However, these frictional properties change with trauma, aging, and disease, resulting in an altered mechanical state within the tissues. Yet, it remains unclear how these surface changes affect the behaviour of embedded cells when the tissue is mechanically loaded. Here, we developed a cytocompatible, bilayered hydrogel system that permits control of surface frictional properties without affecting other bulk physicochemical characteristics such as compressive modulus, mass swelling ratio, and water content...
