Three reflections

Professor Cranfield contributes three short biblical reflections: considering points of contact between the parable of the Good Samaritan and an incident recorded in 2 Chronicles; some points of issue with Francis Watson’s Paul and the Hermeneutics of Faith; and thoughts on ‘the works of the law’ in Romans 3:20, and on Romans, rather than Galatians, being the best way into a study of Paul’s theology

Pesticides and health: A review of evidence on health effects, valuation of risks, and benefit‐cost analysis

In this paper, we provide reviews of recent scientific findings on health effects and preference valuation of health risks related to pesticides, and the role of benefit‐cost analysis in policies related to pesticides. Our reviews reveal that whereas the focus of the health literature has been on individuals with direct exposure to pesticides, e.g. farmers, the literature on preference elicitation has focused on those with indirect exposure, e.g. consumers. Our discussion of pesticides policies emphasizes the need to clarify the rationale for regulation and the role of risk perceptions in benefit‐cost analysis, and stress the importance of inter‐disciplinary research in this area

Ecological drivers of helminth infection patterns in the Virunga Massif mountain gorilla population

The Virunga Massif mountain gorilla population has been periodically monitored since the early 1970s, with gradually increasing effort. The population declined drastically in the 1970s, but the numbers stabilized in the 1980s. Since then, the population has been steadily increasing within their limited habitat fragment that is surrounded by a dense human population. We examined fecal samples collected during the Virunga 2015–2016 surveys in monitored and unmonitored gorilla groups and quantified strongylid and tapeworm infections using egg counts per gram to determine environmental and host factors that shape these helminth infections. We showed that higher strongylid infections were present in gorilla groups with smaller size of the 500-m buffered minimum-convex polygon (MCP) of detected nest sites per gorilla group, but in higher gorilla densities and inhabiting vegetation types occurring at higher elevations with higher precipitation and lower temperatures. On the contrary, the impact of monitoring (habituation) was minor, detected in tapeworms and only when in the interaction with environmental variables and MCP area. Our results suggest that the Virunga mountain gorilla population may be partially regulated by strongylid nematodes at higher gorilla densities. New health challenges are probably emerging among mountain gorillas because of the success of conservation efforts, as manifested by significant increases in gorilla numbers in recent decades, but few possibilities for the population expansion due to limited amounts of habitat

The ATLAS Data Acquisition and High-Level Trigger: Concept, Design and Status

The Trigger and Data Acquisition system (TDAQ) of the ATLAS experiment at the CERN Large Hadron Collider is based on a multi-level selection process and a hierarchical acquisition tree. The system, consisting of a combination of custom electronics and commercial products from the computing and telecommunication industry, is required to provide an online selection power of 105 and a total throughput in the range of Terabit/sec. This paper introduces the basic system requirements and concepts, describes the architecture of the system, discusses the basic measurements supporting the validity of the design and reports on the actual status of construction and installation

The ATLAS trigger - high-level trigger commissioning and operation during early data taking

The ATLAS experiment is one of the two general-purpose experiments due to start operation soon at the Large Hadron Collider (LHC). The LHC will collide protons at a centre of mass energy of 14~TeV, with a bunch-crossing rate of 40~MHz. The ATLAS three-level trigger will reduce this input rate to match the foreseen offline storage capability of 100-200~Hz. This paper gives an overview of the ATLAS High Level Trigger focusing on the system design and its innovative features. We then present the ATLAS trigger strategy for the initial phase of LHC exploitation. Finally, we report on the valuable experience acquired through in-situ commissioning of the system where simulated events were used to exercise the trigger chain. In particular we show critical quantities such as event processing times, measured in a large-scale HLT farm using a complex trigger menu

Work Life Balance up in the Air – Does Gender Make a Difference between Female and Male International Business Travelers?

Managing work-life balance (WLB) has become an issue for both employees and HR departments since WLB tensions may reduce performance, overall job satisfaction and finally, increase the fluctuation rate. Having a balance between job and non-work is a particular challenge for international business travelers, but research on this topic is still in its very infancy. The aim of this article and its underlying qualitative study was to discover factors that influence WLB of those employees, and to explore potential differences among male and female. The results clearly show a big difference in the perception of factors influencing WLB depending on the family situation. This highlights the need of HR departments to offer individually tailored support for the different groups of international business travelers.Das Managen der Work-Life Balance (WLB) ist für immer mehr Arbeitnehmerinnen und Arbeitnehmer als auch Personalabteilungen ein Thema geworden, da ein Ungleichgewicht zwischen Arbeit und 'Nicht-Arbeit' nicht nur Leistung sowie die allgemeine Jobzufriedenheit reduzieren, sondern letztendlich auch zu höheren Fluktuationsraten führen kann. Diese Balance zu halten, ist besonders für internationale Geschäftsreisende eine Herausforderung. Dennoch befindet sich die Forschung zu diesem Thema noch stark in den Kinderschuhen. Ziel dieses Artikels und der zugrundeliegenden qualitativen Studie ist es, die WLB dieser Gruppe von Arbeitnehmern sowie potenzielle Unterschiede zwischen weiblichen und männlichen Vielfliegern zu erörtern. Die Resultate zeigen, dass die Einflussfaktoren auf die WLB in Abhängigkeit von der Familiensituation unterschiedlich wahrgenommen werden. Diese Ergebnisse betonen den Bedarf nach Unterstützungsmaßnahmen seitens der Personalabteilungen, welche für die einzelnen Gruppen von internationalen Geschäftsreisenden maßgeschneidert sind

EXECUTIVE PAY AND PERFORMANCE IN PORTUGUESE LISTED COMPANIES

This essay analyses the relationship between corporate governance practices and Chief Executive Officer (CEO) wages from a sample of Portuguese listed companies over the period from 2002-2011. The relationship between CEO total compensation and shareholders return, firm characteristics, CEO characteristics, board of directors and shareholders characteristics is analysed. It is found that firm specific factors accounts for the majority of the variance in total CEO pay, while firm performance accounts for less than 5%. It is also found that the CEO characteristics, board of directors’ structures, and shareholders features are related with the CEO pay. The policy implications of these results are then derived

The behaviour of giant clams (Bivalvia: Cardiidae: Tridacninae)

Giant clams, the largest living bivalves, live in close association with coral reefs throughout the Indo-Pacific. These iconic invertebrates perform numerous important ecological roles as well as serve as flagship species—drawing attention to the ongoing destruction of coral reefs and their associated biodiversity. To date, no review of giant clams has focussed on their behaviour, yet this component of their autecology is critical to their life history and hence conservation. Almost 100 articles published between 1865 and 2014 include behavioural observations, and these have been collated and synthesised into five sections: spawning, locomotion, feeding, anti-predation, and stress responses. Even though the exact cues for spawning in the wild have yet to be elucidated, giant clams appear to display diel and lunar periodicities in reproduction, and for some species, peak breeding seasons have been established. Perhaps surprisingly, giant clams have considerable mobility, ranging from swimming and gliding as larvae to crawling in juveniles and adults. Chemotaxis and geotaxis have been established, but giant clams are not phototactic. At least one species exhibits clumping behaviour, which may enhance physical stabilisation, facilitate reproduction, or provide protection from predators. Giant clams undergo several shifts in their mode of acquiring nutrition; starting with a lecithotrophic and planktotrophic diet as larvae, switching to pedal feeding after metamorphosis followed by the transition to a dual mode of filter feeding and phototrophy once symbiosis with zooxanthellae (Symbiodinium spp.) is established. Because of their shell weight and/or byssal attachment, adult giant clams are unable to escape rapidly from threats using locomotion. Instead, they exhibit a suite of visually mediated anti-predation behaviours that include sudden contraction of the mantle, valve adduction, and squirting of water. Knowledge on the behaviour of giant clams will benefit conservation and restocking efforts and help fine-tune mariculture techniques. Understanding the repertoire of giant clam behaviours will also facilitate the prediction of threshold levels for sustainable exploitation as well as recovery rates of depleted clam populations
