Assessing the health status of managed honeybee colonies (HEALTHY-B): a toolbox to facilitate harmonised data collection
Tools are provided to assess the health status of managed honeybee colonies by facilitating further
harmonisation of data collection and reporting, design of field surveys across the European Union (EU)
and analysis of data on bee health. The toolbox is based on characteristics of a healthy managed
honeybee colony: an adequate size, demographic structure and behaviour; an adequate production of
bee products (both in relation to the annual life cycle of the colony and the geographical location); and
provision of pollination services. The attributes âqueen presence and performanceâ, âdemography of the
colonyâ, âin-hive productsâ and âdisease, infection and infestationâ could be directly measured in field
conditions across the EU, whereas âbehaviour and physiologyâ is mainly assessed through experimental
studies. Analysing the resource providing unit, in particular land cover/use, of a honeybee colony is
very important when assessing its health status, but tools are currently lacking that could be used at
apiary level in field surveys across the EU. Data on âbeekeeping management practicesâ and
âenvironmental driversâ can be collected via questionnaires and available databases, respectively. The
capacity to provide pollination services is regarded as an indication of a healthy colony, but it is
assessed only in relation to the provision of honey because technical limitations hamper the
assessment of pollination as regulating service (e.g. to pollinate wild plants) in field surveys across the
EU. Integrating multiple attributes of honeybee health, for instance, via a Health Status Index, is
required to support a holistic assessment. Examples are provided on how the toolbox could be used by
different stakeholders. Continued interaction between the Member State organisations, the EU
Reference Laboratory and EFSA is required to further validate methods and facilitate the efficient use
of precise and accurate bee health data that are collected by many initiatives throughout the EU.info:eu-repo/semantics/publishedVersio

Using MapReduce Streaming for Distributed Life Simulation on the Cloud
Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conwayâs life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MRâs applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithmsâ performance on Amazonâs Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp
A complex systems approach to education in Switzerland
The insights gained from the study of complex systems in biological, social, and engineered systems enables us not only to observe and understand, but also to actively design systems which will be capable of successfully coping with complex and dynamically changing situations. The methods and mindset required for this approach have been applied to educational systems with their diverse levels of scale and complexity. Based on the general case made by Yaneer Bar-Yam, this paper applies the complex systems approach to the educational system in Switzerland. It confirms that the complex systems approach is valid. Indeed, many recommendations made for the general case have already been implemented in the Swiss education system. To address existing problems and difficulties, further steps are recommended. This paper contributes to the further establishment complex systems approach by shedding light on an area which concerns us all, which is a frequent topic of discussion and dispute among politicians and the public, where billions of dollars have been spent without achieving the desired results, and where it is difficult to directly derive consequences from actions taken. The analysis of the education system's different levels, their complexity and scale will clarify how such a dynamic system should be approached, and how it can be guided towards the desired performance
