The Rise of Risk in International Law

Risk analysis—a coping mechanism for the uncertainties we see everywhere around us—is on the rise, including at the international level. It now informs, for instance, the work of the Security Council and human rights law and practice. While the story of how risk analysis has inflected international environmental law is frequently told, there has been little attention paid to the way in which risk is increasingly relevant to other areas of international law, including through “due diligence” standards. This Article fills this gap, describing risk’s propagation across different international legal fields. It also offers a taxonomy of the ways in which risk is relevant. This Article distinguishes, for instance, between the way risk sometimes authorizes the state to take an action and situations where the existence of risk obligates the state to react. Finally, this Article seeks to explain potential reasons for risk’s rise and indicate some of the consequences thereof, both salutary (such as greater participation in international legal decision-making) and less so (such as greater horizontal fragmentation of international law)

Indiscriminate Attacks and the Past, Present, and Future of the Rules/Standards and Objective/Subjective Debates in International Humanitarian Law

Civil society, the United Nations, and others are subjecting the conduct of hostilities to increasing scrutiny. But they often lack access to internal targeting data and therefore frequently render legal judgments based on the effects of attacks or assertions that particular weapons or methods of combat are inherently unlawful. This Article analyzes the historical development of key provisions of international humanitarian law (IHL) within the framework of two perennial legal debates--that between rules and standards and that between objective and subjective tests. It argues that while targeting provisions have generally reflected a balance between those two dyads, the jurisprudence of the international criminal tribunals has made IHL more standard-like. It further argues, however, that the contemporary desire for real-time moral and legal clarity is fueling a yearning for a more objective rule-like approach. This Article then uses the prohibition of indiscriminate attacks as a case study and offers specific recommendations for how we might adjust the way we think about that prohibition to respond to the current legal and political environment

Longitudinal Shapes of the Tibia and Femur are Unrelated and Variable

In general practice, short films of the knee are used to assess component position and define the entry point for intramedullary femoral alignment in TKAs; however, whether it is justified to use the short film commonly used in research settings and everyday practice as a substitute for the whole leg view is controversial and needs clarification. In 138 long leg CT scanograms we measured the angle formed by the anatomic axis of the proximal fourth of the tibia and the mechanical axis of the tibia, the angle formed by the anatomic axis of the distal fourth of the femur and the mechanical axis of the femur, the “bow” of the tibia (as reflected by the offset of the anatomic axis from the center of the talus), and the “bow” of the femur (as reflected by the offset of the anatomic axis from the center of the femoral head). Because the angle formed by these axes and the bow of the tibia and femur have wide variability in females and males, a short film of the knee should not be used in place of the whole leg view when accurate assessment of component position and limb alignment is essential. A previous study of normal limbs found that only 2% of subjects have a neutral hip-knee-ankle axis, which can be explained by the wide variability of the bow in the tibia and femur and the lack of correlation between the bow of the tibia and femur in a given limb as shown in the current study

Towards practice-based studies of HRM: an actor-network and communities of practice informed approach

HRM may have become co-terminus with the new managerialism in the rhetorical orthodoxies of the HRM textbooks and other platforms for its professional claims. However, we have detailed case-study data showing that HR practices can be much more complicated, nuanced and indeed resistive toward management within organizational settings. Our study is based on ethnographic research, informed by actor-network theory and community of practice theory conducted by one of the authors over an 18-month period. Using actor-network theory in a descriptive and critical way, we analyse practices of managerial resistance, enrolment and counter-enrolment through which an unofficial network of managers used a formal HRM practice to successfully counteract the official strategy of the firm, which was to close parts of a production site. As a consequence, this network of middle managers effectively changed top management strategy and did so through official HRM practices, coupled with other actor-network building processes, arguably for the ultimate benefit of the organization, though against the initial views of the top management. The research reported here, may be characterized as a situated study of HRM-in-practice and we draw conclusions which problematize the concept of HRM in contemporary management literature

Evidence that vitamin D3 promotes mast cell–dependent reduction of chronic UVB-induced skin pathology in mice

Mast cell production of interleukin-10 (IL-10) can limit the skin pathology induced by chronic low-dose ultraviolet (UV)-B irradiation. Although the mechanism that promotes mast cell IL-10 production in this setting is unknown, exposure of the skin to UVB irradiation induces increased production of the immune modifying agent 1α,25-dihydroxyvitamin D3 (1α,25[OH]2D3). We now show that 1α,25(OH)2D3 can up-regulate IL-10 mRNA expression and induce IL-10 secretion in mouse mast cells in vitro. To investigate the roles of 1α,25(OH)2D3 and mast cell vitamin D receptor (VDR) expression in chronically UVB-irradiated skin in vivo, we engrafted the skin of genetically mast cell–deficient WBB6F1-KitW/W-v mice with bone marrow–derived cultured mast cells derived from C57BL/6 wild-type or VDR−/− mice. Optimal mast cell–dependent suppression of the inflammation, local production of proinflammatory cytokines, epidermal hyperplasia, and epidermal ulceration associated with chronic UVB irradiation of the skin in KitW/W-v mice required expression of VDR by the adoptively transferred mast cells. Our findings suggest that 1α,25(OH)2D3/VDR-dependent induction of IL-10 production by cutaneous mast cells can contribute to the mast cell’s ability to suppress inflammation and skin pathology at sites of chronic UVB irradiation

The first catalytic step of the light-driven enzyme protochlorophyllide oxidoreductase proceeds via a charge transfer complex

In chlorophyll biosynthesis protochlorophyllide reductase (POR) catalyzes the light-driven reduction of protochlorophyllide (Pchlide) to chlorophyllide, providing a rare opportunity to trap and characterize catalytic intermediates at low temperatures. Moreover, the presence of a chlorophyll-like molecule allows the use of EPR, electron nuclear double resonance, and Stark spectroscopies, previously used for the analysis of photosynthetic systems, to follow catalytic events in the active site of POR. Different models involving the formation of either radical species or charge transfer complexes have been proposed for the initial photochemical step, which forms a nonfluorescent intermediate absorbing at 696 nm (

Novel Androgen Receptor Coregulator GRHL2 Exerts Both Oncogenic and Antimetastatic Functions in Prostate Cancer.

Alteration to the expression and activity of androgen receptor (AR) coregulators in prostate cancer is an important mechanism driving disease progression and therapy resistance. Using a novel proteomic technique, we identified a new AR coregulator, the transcription factor Grainyhead-like 2 (GRHL2), and demonstrated its essential role in the oncogenic AR signaling axis. GRHL2 colocalized with AR in prostate tumors and was frequently amplified and upregulated in prostate cancer. Importantly, GRHL2 maintained AR expression in multiple prostate cancer model systems, was required for cell proliferation, enhanced AR's transcriptional activity, and colocated with AR at specific sites on chromatin to regulate genes relevant to disease progression. GRHL2 is itself an AR-regulated gene, creating a positive feedback loop between the two factors. The link between GRHL2 and AR also applied to constitutively active truncated AR variants (ARV), as GRHL2 interacted with and regulated ARVs and vice versa. These oncogenic functions of GRHL2 were counterbalanced by its ability to suppress epithelial-mesenchymal transition and cell invasion. Mechanistic evidence suggested that AR assisted GRHL2 in maintaining the epithelial phenotype. In summary, this study has identified a new AR coregulator with a multifaceted role in prostate cancer, functioning as an enhancer of the oncogenic AR signaling pathway but also as a suppressor of metastasis-related phenotypes.
