Transformation Methods

Abstract We develop a method which assumes that marital preferences are characterized either by the scalar-valued measure proposed by Liu and Lu, or by the matrix-valued generalized Liu–Lu measure. The new method transforms an observed contingency table into a counterfactual table while preserving its (generalized) Liu–Lu value. After exploring some analytical properties of the new method, we illustrate its application by decomposing changes in the prevalence of homogamy in the US between 1980 and 2010. We perform this decomposition with two alternative transformation methods as well where both methods capture preferences differently from Liu and Lu. Finally, we use survey evidence to support our claim that out of the three considered methods, the new transformation method is the most suitable for identifying the role of marital preferences at shaping marriage patterns. These data are also in favor of measuring assortativity in preferences à la Liu and Lu.

Abstract The extracellular matrix is a network of secreted macromolecules that provides a harmonious meshwork for the growth and homeostatic development of organisms. It conveys multiple signaling cascades affecting specific surface receptors that impact cell behavior. During cancer growth, this bioactive meshwork is remodeled and enriched in newly formed blood vessels, which provide nutrients and oxygen to the growing tumor cells. Remodeling of the tumor microenvironment leads to the formation of bioactive fragments that may have a distinct function from their parent molecules, and the balance among these factors directly influence cell viability and metastatic progression. Indeed, the matrix acts as a gatekeeper by regulating the access of cancer cells to nutrients. Here, we will critically evaluate the role of selected matrix constituents in regulating tumor angiogenesis and provide up-to-date information concerning their primary mechanisms of action.

The methods of chemical structural alteration of small organic molecules by using microbes (fungi, bacteria, yeast, etc.) are gaining tremendous attention to obtain structurally novel and therapeutically potential leads. The regiospecific mild environmental friendly reaction conditions with the ability of novel chemical structural modification in compounds categorize this technique; a distinguished and unique way to obtain medicinally important drugs and their in vivo mimic metabolites with costeffective and timely manner. This review article shortly addresses the immense pharmaceutical importance of microbial transformation methods in drug designing and development as well as the role of CYP450 enzymes in fungi to obtain in vivo drug metabolites for toxicological studies.

Expanding beyond the text of the Bible, this chapter explores instead a piece of political scripture, namely the Second Amendment of the US Constitution. Over the last half-decade, the Second Amendment has come to enjoy the status of a kind of scripture-within-scripture. Vaulted to a much more prominent status than it had held in the first 150 years or so of its existence, and having undergone a remarkable shift in what most Americans think it means, the Second Amendment provides an opportunity to examine the linguistic, racial, and gendered modes by which these changes were effected, paying particular attention to the ways in which white children and white women were conscripted into the role of the masculine, frontier-defending US citizen.

The role of children in Merovingian society has long been downplayed, and the study of their graves and bones has long been neglected. However, during the past fifteen years, archaeologists have shown growing interest in the place of children in Merovingian society. Nonetheless, this research has not been without challenges linked to the nature of the biological and material remains. Recent analysis of 315 children’s graves from four Merovingian cemeteries in northern Gaul (sixth to seventh centuries) allows us to understand the modalities of burial ritual for children. A new method for classifying children into social age groups shows that the type, quality, quantity, and diversity of grave goods were directly correlated with the age of the deceased. They increased from the age of eight and particularly around the time of puberty. This study discusses the role of age and gender in the construction and expression of social identity during childhood in the Merovingian period.

Diverse Data

Medicare uses a pay-for-performance program to reimburse hospitals. One of the key input measures in the performance formula is patient satisfaction with their hospital care. Physicians and hospitals, however, have raised concerns especially about questions related to patient satisfaction with pain management during hospitalization. They report feeling pressured to prescribe opioids to alleviate pain and boost satisfaction survey scores for higher reimbursements. This over-prescription of opioids has been cited as a cause of current opioid crisis in the US. Due to these concerns, Medicare stopped using pain management questions as inputs in its payment formula. We collected multi-year data from six diverse data sources, employed propensity score matching to obtain comparable groups, and estimated difference-in-difference models to show that, in fact, pain management was the only measure to improve in response to pay-for-performance system. No other input measure showed significant improvement. Thus, removing pain management from the formula may weaken the effectiveness of HVBP program at improving patient satisfaction, which is one of the key goals of the program. We suggest two divergent paths for Medicare to make the program more effective.

Abstract The prevalence of caregiving for an adult or child with special needs has increased significantly in the past five years (from 18.2% to over 21.3%), driven by an increase in the prevalence of caring for a family member or friend aged 50 and older. At the same time, care recipients have greater health and functional needs that necessitate care from others in comparison to 2015. These new 2020 data from the Caregiving in the US Survey by the National Alliance for Caregiving suggests that not only are more American adults taking on the role of caregiver, but they are doing so for increasingly complex care situations. This paper addresses the prevalence of caregiving including the demographics of family caregivers, relationship between the caregiver and the care recipient, health conditions of the care recipient, and living situations of care recipients and their caregivers.

The past ten years have witnessed a revival in scholarship on militarism, through which scholars have used the concept to make sense of the embeddedness of warlike relations in contemporary liberal societies and to account for how the social, political and economic contours of those same societies are implicated in the legitimation and organization of political violence. However, a persistent shortcoming has been the secondary role of race and coloniality in these accounts. This article demonstrates how we might position racism and colonialism as integral to the functioning of contemporary militarism. Centring the thought and praxis of the US Black Panther Party, we argue that the particular analysis developed by Black Panther Party members, alongside their often-tense participation in the anti–Vietnam War movement, offers a strong reading of the racialized and colonial politics of militarism. In particular, we show how their analysis of the ghetto as a colonial space, their understanding of the police as an illegitimate army of occupation and, most importantly, Huey Newton’s concept of intercommunalism prefigure an understanding of militarism premised on the interconnections between racial capitalism, violent practices of un/bordering and the dissolving boundaries between war and police action.
