The usefulness of mobile devices has increased greatly in recent years allowing users to perform more tasks in a mobile context. This increase in usefulness has come at the expense of the usability of these devices in some contexts. We conducted a small review of mobile usability models and found that usability is usually measured in terms of three attributes; effectiveness, efficiency and satisfaction. Other attributes, such as cognitive load, tend to be overlooked in the usability models that are most prominent despite their likely impact on the success or failure of an application. To remedy this we introduces the PACMAD (People At the Centre of Mobile Application Development) usability model which was designed to address the limitations of existing usability models when applied to mobile devices. PACMAD brings together significant attributes from different usability models in order to create a more comprehensive model. None of the attributes that it includes are new, but the existing prominent usability models ignore one or more of them. This could lead to an incomplete usability evaluation. We performed a literature search to compile a collection of studies that evaluate mobile applications and then evaluated the studies using our model.

Stock synthesis: A biological and statistical framework for fish stock assessment and fishery management

From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain's gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries.

Forensic Archaeology: Advances in Theory and Practice

The study of forensic evidence using archaeology is a new discipline which has rapidly gained importance, not only in archaeological studies but also in the investigation of real crimes. Archaeological evidence is increasingly presented in criminal cases and has helped to secure a number of convictions. Studies in Crime surveys methods of searching for and locating buried remains, their practical recovery, the decay of human and associated death scene materials, the analysis and identification of human remains including the use of DNA, and dating the time of death. The book contains essential information for forensic scientists, archaeologists, police officers, police surgeons, pathologists and lawyers. Studies in Crime will also be of interest to members of the public interested in the investigation of death by unnatural causes, both ancient and modern.

Crime scene investigation is a form of Distributed Cognition. The principal concept we explore in this paper is that of ‘resource for action’. It is proposed that crime scene investigation employs four primary resources-for-action: (a.) the environment, or scene itself, which affords particular forms of search and object retrieval; (b.) the retrieved objects, which afford translation into evidence; (c.) the procedures that guide investigation, which both constrain the search activity and also provide opportunity for additional activity; (d.) the narratives that different agents within the system produce to develop explanatory models and formal accounts of the crime. For each aspect of distributed cognition, we consider developments in technology that could support activity.

Crime scene investigation as distributed cognition

The annual egg production method (Saville, 1964) has been widely used for estimating the biomass of adult fish from the numbers of planktonic eggs. Parker (1980) showed how a daily egg production method could also be used to estimate adult fish biomass. Subsequently, the daily egg production method has
