Summary
This chapter explores the relationships between environmental stresses, natural resource shortages, and violent conflict. It describes ideas such as tragedy of the commons, carrying capacity, and common pool resources, as well as Malthusian theories. It also explains how environmental stresses can affect various kinds of conflict, through dynamics such as states sharing transboundary water resources clashing over maritime assets such as fishing and petrochemical reserves; resource shortages fueling conflicts over distribution among substate populations; and shortages causing internal migration, in turn fueling "sons of the soil" conflicts. It also describes how state capacity, rural economies, and groupness can affect the connection between environmental stresses and conflict. The chapter discusses how conflict can in turn exacerbate environmental stresses, and pays special attention to the consequences of climate change for conflict. The chapter applies many of these concepts to a quantitative study on the relationship between drought and conflict, and a case study on the role of drought in causing the Syrian Civil War.

Over the past fifteen years, a narrative has developed that IR scholars have become a “cult of the irrelevant,” with declining influence on and engagement with policy debates. Despite these assertions, the evidence for limited policy engagement has been anecdotal. We investigate the extent of policy engagement—the ways in which IR scholars participate in policy-making processes and/or attempt to shape those processes—by surveying IR scholars directly about their engagement activities. We find policy engagement is pervasive among IR scholars. We draw on theories of credit-claiming to motivate expectations about how and when scholars are likely to engage with practitioners. Consistent with our expectations, much of this engagement comes in forms that involve small time commitments and provide opportunities for credit-claiming, such as media appearances and short-form, bylined op-eds and blog posts. However, sizable minorities report engaging in consulting activities not for attribution/publication and writing policy briefs, and a majority of respondents indicate they engaged in these activities several times a year or more. We find only small differences in engagement across gender and rank. Our results demonstrate that, for IR scholars, some form of policy engagement is the norm.

Objective:
Optimizing needleless connector hub disinfection practice is a key strategy in central-line–associated bloodstream infection (CLABSI) prevention. In this mixed-methods evaluation, 3 products with varying scrub times were tested for experimental disinfection followed by a qualitative nursing assessment of each.
Methods:Needleless connectors were inoculated with varying concentrations of Staphylococcus epidermidis, Pseudomonas aeruginosa, and Staphylococcus aureus followed by disinfection with a 70% isopropyl alcohol (IPA) wipe (a 15-second scrub time and a 15-second dry time), a 70% IPA cap (a 10-second scrub time and a 5-second dry time), or a 3.15% chlorhexidine gluconate with 70% IPA (CHG/IPA) wipe (a 5-second scrub time and a 5-second dry time). Cultures of needleless connectors were obtained after disinfection to quantify bacterial reduction. This was followed by surveying a convenience sample of nursing staff with intensive care unit assignments at an academic tertiary hospital on use of each product.
Results:All products reduced overall bacterial burden when compared to sterile water controls, however the IPA and CHG/IPA wipes were superior to the IPA caps when product efficacy was compared. Nursing staff noted improved compliance with CHG/IPA wipes compared with the IPA wipes and the IPA caps, with many preferring the lesser scrub and dry times required for disinfection.
Conclusion:Achieving adequate bacterial disinfection of needleless connectors while maximizing healthcare staff compliance with scrub and dry times may be best achieved with a combination CHG/IPA wipe.

Background: An oral, fixed-dose sodium phenylbutyrate-ursodoxicoltaurine (PB-TURSO) coformulation was evaluated in a multicenter ALS trial (CENTAUR). Methods: Adults with definite ALS, ≤18 months from symptom onset, (N=137) were randomized 2:1 to PB-TURSO or placebo for 6 months. Completing participants were eligible to receive PB-TURSO in the open-label extension (OLE) (≤30 months). The primary efficacy endpoint in both periods was rate of ALS Functional Rating Scale–Revised (ALSFRS-R) total score decline. All-cause survival was analyzed July 2020 (longest follow-up, 35 months). Safety was assessed in both periods. Results: Over 6-month randomized treatment, mean ALSFRS-R total score decline was slower with PB-TURSO vs placebo (difference, 0.42 points/month; P=0.03). Participants receiving PB-TURSO in the OLE (continued or crossover from placebo) maintained or initiated functional benefit beyond 6 months of therapy. Mean hazard of death was 44% lower (P=0.02) in the original PB-TURSO group. Overall adverse event (AE) incidence was similar, though early (week ≤3) gastrointestinal AEs were more frequent during initial exposure to PB-TURSO (randomized period or OLE). Conclusions: PB-TURSO resulted in superior retention of function in the randomized period. Long-term OLE results support functional benefits of early vs delayed therapy and of sustained treatment. Survival was longer in the original PB-TURSO group after nearly 3 years.

To investigate the manipulation of electromagnetic properties of two-dimensional materials, this effort characterizes charge transfer behavior of colloidal COF-5 (covalent organic framework) in the presence of various metal ions. A series of metal chloride compounds was introduced to COF-5 in solution and solid film phases and the interaction of the material with electromagnetic radiation was monitored across the visible region using electronic absorption spectroscopy. Notable changes were observed, quantified, and discussed for copper (II) chloride (CuCl2), chromium (III) chloride (CrCl3), and iron (III) chloride (FeCl3) with COF-5. Ligand-to-metal and metal-to-ligand charge transfer are explored as a possible mechanism for the observed electronic behaviors.

In Belgium, the preferred long-term management option for Eurobitum bituminized ILW is its final disposal in a geologically stable clay formation such as the Boom Clay, which is studied as a reference host formation. After disposal, clay pore water will infiltrate the secondary concrete waste containers filled each with ten Eurobitum drums. Eurobitum contains hygroscopic salts, mostly NaNO3 (20-30 wt%) and CaSO4 (4-6 wt%), and thus will take up water and swell. If swelling is hindered, a pressure will be exerted on the concrete container and ultimately on the surrounding Boom Clay, possibly inducing stresses in the clay close to the disposal galleries. To improve our understanding of these processes, water uptake tests are ongoing in which inactive Eurobitum is contacted with 0.1 M KOH (representing young cement water). These tests suggest that the swelling is mainly driven by osmosis. This understanding was validated in the presented research by varying the water activity of the leachant in water uptake tests in both constant stress and constant volume conditions. After a stable swelling rate was reached in contact with 0.1 M KOH, the leachant was switched in the following order: nearly saturated (∼7.8 M) NaNO3 – 0.1 M KOH – nearly saturated NaNO3 – 4 M NaNO3 – 0.1 M KOH. The changes in swelling rate and pressure evolution correlated nicely to the changes in water activity. This confirms that osmosis is the key process governing the swelling of Eurobitum.

Does naming and shaming states affect respect for human rights in those states? This article argues that incentives to change repressive behaviour when facing international condemnation vary across regime types. In democracies and hybrid regimes – which combine democratic and authoritarian elements – opposition parties and relatively free presses paradoxically make rulers less likely to change behaviour when facing international criticism. In contrast, autocracies, which lack these domestic sources of information on abuses, are more sensitive to international shaming. Using data on naming and shaming taken from Western press reports and Amnesty International, the authors demonstrate that naming and shaming is associated with improved human rights outcomes in autocracies, but with either no effect or a worsening of outcomes in democracies and hybrid regimes.

During the nanoindentation process, the load and depth data are continuously recorded. A single load-displacement curve is thus expected to contain material property information from the whole depth range indented. In the present paper, a new method to obtain the hardness-depth curve has been derived for small depths from the load-displacement curve measured at a large depth, based on the assumption that the elastic properties of the indented material can be obtained from the indentation depth. Using this method, hardness values can be computed for various small depths from a single load-displacement curve. From a series of nanoindentation experiments, it has been proven that the method can be used on both homogeneous and surface-modified materials, such as fused silica, single crystal tungsten, and plasma nitrided steel with and without an iron nitride Fe4N compound layer. Testings on a series of Ni–P films coated on 15 MnB steel also gave fairly good results.

The results show that unlike those made by physical vapour deposition, Ti(C,N) coatings made by plasma assisted chemical vapour deposition are composed of two phases, TiN and TiC. With the formation of two phases, the columnar structure vanishes gradually and the crystal size becomes small. The carbon content is the dominant controlling factor for a linear increase in microhardness of the coatings, but the residual macrostress and the adhesive strength evaluated under cyclic contact conditions are dependent to a great extent on the percentage of the two phases. There is an intermediate carbon content for the present Ti(C,N) coatings which yields a fine mixed microstructure and optimum mechanical properties.
