DNA traces the origin of honey by identifying plants, bacteria and fungi
2021
The regional origin of a food product commonly affects its value. To this, DNA-based identification of tissue remains could offer fine resolution. For honey, this would allow the usage of not only pollen but all plant tissue, and also that of microbes in the product, for discerning the origin. Here we examined how plant, bacterial and fungal taxa identified by DNA metabarcoding and metagenomics differentiate between honey samples from three neighbouring countries. To establish how the taxonomic contents of honey reflect the country of origin, we used joint species distribution modelling. At the lowest taxonomic level by metabarcoding, with operational taxonomic units, the country of origin …
Chaotic multiagent system approach for MRF-based image segmentation
2005
In this paper, we propose a new chaotic approach for image segmentation based on multiagent system (MAS). We consider a set of segmentation agents organized around a coordinator agent. Each segmentation agent performs iterated conditional modes (ICM) starting from its own initial image created using a chaotic mapping. The coordinator agent diversifies the initial images using a crossover and a chaotic mutation operators. The efficiency of our chaotic MAS approach is shown through some experimental results.
An Activity Theory Perspective on Creating a New Digital Government Service in Finland
2019
Digitalization of government services is a central goal in many countries. At policy-making level, digital government services are often expected to simultaneously reduce cost and provide citizens with better and more versatile services. Development of new digital government services, however, often involves companies, which typically have differences in their approach to the development and implementation of new digital services compared to the public sector. This study applies activity theory as a lens to identify the similarities and differences between the private and public sector in the development and implementation of a new government digital service. The aim is to identify the cont…
An Observation Framework for Multi-agent Systems
2009
Existing middleware platforms for multi-agent systems (MAS) do not provide general support for observation. On the other hand, observation is considered to be an important mechanism needed for realizing effective and efficient coordination of agents. This paper describes a framework called Agent Observable Environment (AOE) for observation-based interaction in MAS. The framework provides 1) possibility to model MAS components with RDF-based observable soft-bodies, 2) support for both query and publish/subscribe style ontology-driven observation, and 3) ability to restrict the visibility of observable information using observation rules. Additionally, we report on an implementation of the fr…
Multi-Platform Agent Systems with Dynamic Reputation Policy Management
2011
Open, distributed multi-platform agent systems require new management approaches for resources and data secure access. In this paper a Jade-S based multi-platform agent system implementing dynamic reputation policy management is proposed. The implemented extension deals with biometrics, X-Security, DES cryptography and agent reputation. With more details, the proposed reputation management system helps to assess the agent's behavior and reliability, in order to select trusted agents. This is made possible by the knowledge that agents are able to acquire, over time, and that allows them to choose the best solution using own intelligence in total autonomy.
BIOMECHANICS AND NEUROSCIENCE IN SPORTS: FOCUS ON THE EFFECTS OF PRISMATIC ADAPTATION ON POSTURE AND SPORTS SKILLS ACCURACY

Malinteso
2012
Il malinteso, nella sua impalpabilità, si propone come vero protagonista del mondo contemporaneo. Esso si mostra nei suoi effetti e si nasconde nelle sue origini. Il malinteso appartiene al momento presente ma si rivela sempre in un secondo momento, quando degenera nel conflitto e nell’interruzione delle interazioni. L’ipotesi del mio lavoro è che la diffusione del malinteso, nella realtà quotidiana delle relazioni umane e sociali, debba ricercarsi nell’assenza di un quadro certo e definito, in una realtà sociale che è priva di riferimenti stabili. Il dispositivo clinico, che nel lavoro di cura è la base di ogni intervento, nell’incertezza del quadro generale, nella trasmutazione dei valori…
Negoziazioni: aspetti metodologici e territori di confine nel racconto di vita di Gaspare Spatuzza
2017
Il paper approfondisce alcune questioni metodologiche emerse nel corso di un progetto di ricerca iniziato nell’ottobre del 2012, quando – ottenute le formali autorizzazioni – ho intervistato per la prima volta Gaspare Spatuzza. Gli incontri – 9 in tutto e dispiegatisi lungo l’arco di un anno fino all’ottobre del 2013 – si sono svolti all’interno della struttura carceraria in località protetta dove Spatuzza si trovava detenuto. La ricerca si è conclusa con la pubblicazione di un volume dal titolo A colloquio con Gaspare Spatuzza. Un racconto di vita. Una storia di stragi (Bologna, il Mulino, 2016). I temi oggetto di approfondimento di questo lavoro sono stati al centro dei miei interessi di …
Sex roles and sex ratios in animals
2022
In species with separate sexes, females and males often differ in their morphology, physiology and behaviour. Such sex-specific traits are functionally linked to variation in reproductive competition, mate choice and parental care, which have all been linked to sex roles. At the 150th anniversary of Darwin's theory on sexual selection, the question of why patterns of sex roles vary within and across species remains a key topic in behavioural and evolutionary ecology. New theoretical, experimental and comparative evidence suggests that variation in the adult sex ratio (ASR) is a key driver of variation in sex roles. Here, we first define and discuss the historical emergence of the sex role c…
The effects of using participatory working time scheduling software on working hour characteristics and wellbeing : a quasi-experimental study of irr…
2020
Background: Studies in the health care sector indicate that good work time control is associated with better perceived wellbeing but also with non-ergonomic work schedules, such as compressed work schedules. Participatory working time scheduling is a collaborative approach to scheduling shift work. Currently, there is a lack of information on whether working hour characteristics and employees' wellbeing in irregular shift work change after implementing participatory working time scheduling. Objective: To investigate the effects of using digital participatory working time scheduling software on working hour characteristics and well-being among Finnish hospital employees. Participants and met…
