Stay the hand of justice? Evaluating claims that war crimes trials do more harm than good

An enduring dilemma in war is whether and how to punish those responsible for war crimes. In this essay, we analyze the most frequent criticisms made by war crimes trial skeptics, including the claims that such trials endanger prospects for peace by encouraging enemies to continue fighting, that they achieve only “victors’ justice” rather than real justice, and that, in any event, they are unnecessary due to the existence of more effective and less costly alternatives. We conclude, in accordance with a “moderate retributivism,” that when carried out consistently with established law and procedure, and when not dramatically outweighed by concerns that trials will exacerbate ongoing or future conflicts, prosecutions are a legitimate, and sometimes necessary, response to violations of the laws of war and international criminal law more broadly

Evaluations of co-brands: a two-country comparison

This paper explores consumer reactions to a brand alliance, with perceptions of the parent brands, perceived fit between the brands and fit between product categories as the drivers. Drawing on previous work on co-brands (Simonin and Ruth, 1998; Baumgarth, 2000), two simultaneous studies of four consumer brand pairings were conducted in the UK (n=122) and Italy (n=125) using respondents from an online panel. Important differences between the studies are identified and possible cultural explanations for deviant outcomes are discussed

Cost-effectiveness Analysis of Hypoallergenic Milk Formulas for the Management of Cow’s Milk Protein Allergy in the United Kingdom

**Background:** Cow’s milk protein allergy (CMPA) is the most common food allergy in early childhood. In most children CMPA resolves by age 5 or 6; however, if not treated correctly can provoke nutritional deficiency resulting in poor growth. Management consists of excluding cow’s milk from the diet, with hypoallergenic formulas (or non-dairy alternatives) being introduced to meet nutritional requirements. **Objectives:** To compare the cost-effectiveness of hypoallergenic formulas in reducing allergic manifestations and promoting immune tolerance in infants with immunoglobulin E (IgE)-mediated symptoms of CMPA. **Methods:** A trial-based decision analytic cohort model was developed to simulate the occurrence of urticaria, eczema, asthma, rhinoconjunctivitis, or being symptom-free in infants with CMPA in the United Kingdom. Amino acid-based formula (AAF), extensively hydrolysed casein formula containing Lactobacillus rhamnosus Gorbach Goldin (EHCF+LGG), extensively hydrolysed whey formula (EHWF), and soy formula (SF) were compared using the National Health Service (NHS) perspective, 3-year time horizon and 3.5% discount rate for cost and health consequences. Hypoallergenic formulas comparative efficacy was sourced from a prospective cohort study. Resources required to manage allergic symptoms were sourced from published literature, validated by a UK clinician, and applied to UK cost resources. Results were reported as cost per additional child free from allergic manifestations at 3 years and cost per additional immune tolerant child at 3 years. **Results:** In the base case, infants receiving EHCF+LGG were associated with lower NHS resource use and improved CMPA tolerance. Over the 3-year treatment period, savings of £119, £476, and £1094 were achieved with EHCF+LGG compared to SF, EHWF and AAF, respectively. Infant formula accounted for the largest proportion of resource consumption averaging 44% for all comparators, with a minimum of 31% for SF and a maximum of 53% for AAF over 3 years. General practitioners’ visits constituted the second highest cost component, approximately 17% of total costs across comparators. The results were robust to deterministic and probabilistic sensitivity analyses. **Conclusions:** Compared to AAF, SF, and EHWF hypoallergenic formulas, EHCF+LGG was the most cost-effective, associated with lower total costs and contributing to a higher proportion of children being symptom-free and developing immune tolerance 3-years after diagnosis

Passive Aeroelastic Tailoring

The Passive Aeroelastic Tailoring (PAT) project was tasked with investigating novel methods to achieve passive aeroelastic tailoring on high aspect ratio wings. The goal of the project was to identify structural designs or topologies that can improve performance and/or reduce structural weight for high-aspect ratio wings. This project considered two unique approaches, which were pursued in parallel: through-thickness topology optimization and composite tow-steering

Complex CatSper-dependent and independent [Ca2⁺]i signalling in human spermatozoa induced by follicular fluid

STUDY QUESTION: Does progesterone in human follicular fluid (hFF) activate CatSper and do other components of hFF modulate this effect and/or contribute separately to hFF-induced Ca2+ signaling?SUMMARY ANSWER: hFF potently stimulates CatSper and increases [Ca2+]i, primarily due to high concentrations of progesterone, however,other components of hFF also contribute to [Ca2+]i signaling, including modulation of CatSper channel activity and inhibition of [Ca2+]i oscillations.WHAT IS KNOWN ALREADY: CatSper, the principal Ca2+ channel in spermatozoa, is progesterone-sensitive and essential for fertility. Both hFF and progesterone, which is present in hFF, influence sperm function and increase their [Ca2+]i.STUDY DESIGN, SIZE, DURATION: This basic medical research study used semen samples from >40 donors and hFF from >50 patients who were undergoing surgical oocyte retrieval for IVF/ICSI.PARTICIPANTS/MATERIALS, SETTING, METHODS: Semen donors and patients were recruited in accordance with local ethics approval (13/ES/0091) from the East of Scotland Research Ethics Service REC1. Activities of CatSper and KSper were assessed by patch clamp electrophysiology. Sperm [Ca2+]i responses were examined in sperm populations and single cells. Computer-assisted sperm analysis (CASA) parameters and penetration into viscous media were used to assess functional effects.MAIN RESULTS AND THE ROLE OF CHANCE: hFF and progesterone significantly potentiated CatSper currents. Under quasiphysiologicalconditions, hFF (up to 50%) failed to alter membrane K+ conductance or current reversal potential. hFF and progesterone (at an equivalent concentration) stimulated similar biphasic [Ca2+]i signals both in sperm populations and single cells. At a high hFF concentration (10%), the sustained (plateau) component of the [Ca2+]i signal was consistently greater than that induced by progesterone alone. In single cell recordings, 1% hFF-induced [Ca2+]i oscillations similarly to progesterone but with 10% hFF generation of [Ca2+]i oscillations was suppressed. After treatment to ‘strip’ lipid-derived mediators, hFF failed to significantly stimulate CatSper currents but induced small [Ca2+]i responsesthat were greater than those induced by the equivalent concentration of progesterone after stripping. Similar [Ca2+]i responses were observed when sperm pretreated with 3 μM progesterone (to desensitize progesterone responses) were stimulated with hFF or stripped hFF. hFF stimulated viscous media penetration and was more effective than the equivalent does of progesterone.LARGE SCALE DATA: N/A.LIMITATIONS, REASONS FOR CAUTION: This was an in vitro study. Caution must be taken when extrapolating these results in vivo.WIDER IMPLICATIONS OF THE FINDINGS: This study directly demonstrates that hFF activates CatSper and establishes that the biologically important effects of hFF reflect, at least in part, action on this channel, primarily via progesterone. However, these experiments also demonstrate that other components of hFF both contribute to the [Ca2+]i signal and modulate the activation of CatSper. Simple in vitro experiments performed out of the context of the complex in vivo environment need to be interpreted with caution
