The relevance of psychosocial maps in the study of urban districts
2011
Abstract This pilot study proposes a social map-making method based on the link between the evaluation of the neighbourhoods and the populations residing in them. It was carried on a sample of residents of Dijon’s urban area, a French city (N = 99) divided into four groups, according to the geographical location (in the city / in the suburbs) and the social status (wealthy / disadvantaged) of their living space. The procedure is inspired by social representation gathering methods. Respondents were asked (1) to evaluate their own neighbourhood and others on two scales (social reputation and personal appreciation); (2) to evaluate populations on two similar scales; (3) to determine how these …
Ar LoRaWAN raidītājiem aprīkotu objektu monitoringa sistēma
2022
Putnu migrācijas pētījumi palīdz uzzināt daudz jauna par putnu dzīvesveidu. Šiem pētījumiem bieži tiek izmantoti nelieli putni, jo tie ir vieglāk pieejami. Nelielu putnu migrācijas pētījumos šobrīd īsti nav iespēju noteikt putnu lokāciju migrācijas laikā. Izmantojot šā brīža modernākās ierīces, putnu migrācijā dati tiek iegūti, uzliekot vides uztveršanas ierīci putnam, noņemot to nākamajā ligzdošanas periodā (pēc gada). Migrācijas ceļi pēc šādas metodes tiek rēķināti no sensoru datiem pēc tam, kad putns ir atgriezies ligzdošanas vietā. Tā kā putna ķermenis ir viegls, tad arī ierīcei, kas lokācijas datus pārraidītu, ir jābūt nelielai, vieglai un ar zemu enerģijas patēriņu. Darbā apskatītais …
The network of heliports as a necessary tool to develop rotorcraft services
2012
The rotorcraft operations will grow as air taxi services and business trips and even as “commuter”, intercity and line services between urban centres and touristic or economic-industrial places of special value. But actually the rising public opposition to helicopter activities reduces the number of available heliports for private and corporate operators, as environmental limits of all type of allowed operations and of suitable sites to construct new infrastructures. So the growth of scheduled rotorcraft services (passengers and freights) has to be supported not only by advances in machine’s technologies, but also by an adequate and strategically distributed infrastructure network. This vis…
Pricing of electricity futures based on locational price differences : empirical evidence from Finland
2016
Tietyn maantieteellisen alueen kilpailullisilla sähkömarkkinoilla on yleensä viitespot-hinta, joka kuvastaa yleistä hintatasoa tukkumarkkinalla, ja jota käytetään johdannaisten viitehintana. Paikallisten markkinoiden hinnat saattavat kuitenkin poiketa tästä viitehinnasta siirtoyhteyksien rajallisuuden takia. Pohjoismaisilla sähkömarkkinoilla ns. systeemi- ja tarjousalueen aluehinnan väliseltä basis-riskiltä suojaudutaan ns. aluehintaero-johdannaisilla (eng. Electricity Price Area Differential, EPAD). Tutkin tässä pro gradu- työssä Suomen tarjousalueen EPAD-tuotteiden ja vastaavan aluehintaeron yhteyttä. Koska sähkö ei ole varastoitavissa, yleisen näkemyksen mukaan sopiva sähköfutuurien hinn…
Multi-objective human resources allocation in R&D projects planning
2009
In a R&D department, several projects may have to be implemented simultaneously within a certain period of time by a limited number of human resources with diverse skills. This paper proposes an optimisation model for the allocation of multi-skilled human resources to R&D projects, considering individual workers as entities having different knowledge, experience and ability. The model focuses on three fundamental aspects of human resources: the different skill levels, the learning process and the social relationships existing in working teams. The resolution approach for the multi-objective problem consists of two steps: firstly, a set of non-dominated solutions is obtained by exploring the…
Intensive Management and Natural Genetic Variation in Red Deer (Cervus elaphus)
2017
The current magnitude of big-game hunting has outpaced the natural growth of populations, making artificial breeding necessary to rapidly boost hunted populations. In this study, we evaluated if the rapid increase of red deer (Cervus elaphus) abundance, caused by the growing popularity of big-game hunting, has impacted the natural genetic diversity of the species. We compared several genetic diversity metrics between 37 fenced populations subject to intensive management and 21 wild free-ranging populations. We also included a historically protected population from a national park as a baseline for comparisons. Contrary to expectations, our results showed no significant differences in geneti…
Echolocating Whales and Bats Express the Motor Protein Prestin in the Inner Ear: A Potential Marker for Hearing Loss.
2020
Prestin is an integral membrane motor protein located in outer hair cells of the mammalian cochlea. It is responsible for electromotility and required for cochlear amplification. Although prestin works in a cycle-by-cycle mode up to frequencies of at least 79 kHz, it is not known whether or not prestin is required for the extreme high frequencies used by echolocating species. Cetaceans are known to possess a prestin coding gene. However, the expression and distribution pattern of the protein in the cetacean cochlea has not been determined, and the contribution of prestin to echolocation has not yet been resolved. Here we report the expression of the protein prestin in five species of echolo…
Les organisations publiques : des institutions communicantes ? Le cas des Caisses d'Allocations Familiales
2009
L’objectif de cet article est de proposer une approche comprehensive de la communication des organisations publiques a travers le cas des Caisses d’Allocations Familiales (CAF). Les travaux dont il est issu ont eu pour objet d’interroger les representations des cadres, charges de communication et directeurs des CAF autour de la notion d’institution communicante. Il s’agit notamment de preciser si celle-ci releve d’un artefact ou pourrait -et a quelles conditions- constituer un modele valide pour analyser la communication des organisations publiques.
A Location Based Service for the production of interactive photographs
2010
Currently, photographs are an indispensable means for documenting and surveying objects and places, however, they have an inherent limitation due to a lack of identification data. Digital applications on a photograph could resolve this limitation. This paper, therefore, details the results of a research based on an innovative photographic system, with the purpose of identifying objects in digital photos. To carry out this procedure, this is achieved by partly utilizing a Location Based Service. The final product, obtained from the user in real time with a simple shot of the photo, constitutes a small information system, which enables the analysis of the images of places and objects in an in…
History Matters: Colonial‑Based Connectivity and Foreign Headquarter Location Choice
2022
AbstractIn this study, we argue that European countries’ extensive relationships with former colonies represent a location factor that attracts foreign headquarter investments. The strategic role of foreign headquarters as coordinators, opportunity detectors, and global bridgeheads makes the location choice of headquarter activities sensitive to historical-based institutional connections. Drawing on a sample of 2230 foreign headquarter investments in Europe, we find that the stronger the combined effect of historical connections and current economic relationships with former colonies, the higher the probability of attracting headquarter investment projects. We refer to this combined charact…
