Contributions to Improve the Sustainability in Services Based Organizations

2018

The sustainability of the services based organization consist on its ability to monitor the external environment about opportunities, changes, trends and risks, as well as the ability to learn, change and innovate. To reach the sustainability threshold, the organization must focus on both results and processes. A viable solution is to adopt a quality strategy that allows a perceptible perception of its products to its customers. This research purpose is to identify the extent of which organizations are sustainable and seek to meet the interests of all the involved stakeholders, as well as to help the organizations to identify areas where they can improve their performance.

Seasonal changes in predator community switch the direction of selection for prey defences

2014

Insect communities consist of aposematic species with efficient warning colours against predation, as well as abundant examples of crypsis. To understand such coexistence, we here report results from a field experiment where relative survival of artificial larvae, varying in conspicuousness, was estimated in natural bird communities over an entire season. This takes advantage of natural variation in the proportion of naive predators: naivety peaks when young birds have just fledged. We show that the relative benefit of warning signals and crypsis changes accordingly. When naive birds are rare (early and late in the season), conspicuous warning signals improve survival, but conspicuousness b…

Effects of stump removal on soil decomposer communities in undisturbed patches of the forest floor

2011

Abstract Soil preparation after clear-cutting leads to fragmentation of forest floor and, consequently, changes the habitat of decomposers. Stump removal for bioenergy is further increasing the disturbance in the soil. We studied responses of decomposers to stump removal in boreal spruce forests during the first 4 years after clear felling in relation to mounding. Samples for each decomposer organism group were taken from undisturbed forest floor patches that are the main habitat for decomposers after forest regeneration and whose amount and size obviously differ between the treatments. Microbial biomasses and community structure, and the abundance of enchytraeids, were not found to be affe…

Habitat patchiness affects decomposition and faunal diversity: a microcosm experiment on forest floor.

1998

Environmental heterogeneity has been intensively studied, but little is known about relationships between habitat patchiness and soil processes. The aim of this study was to investigate (1) the impact of patchiness of the litter layer on the decomposer community and litter decomposition rate, and (2) whether the impact of soil fauna on the rates of processes differs in relation to patchiness. An experiment was carried out in microcosms with coniferous forest humus and four kinds of litter with different C:N ratios or stages of decomposition, either separately (i.e. in patches) or mixed with each other. Microarthropod species diversity was better maintained in the patchy systems. In the abse…

Short-term responses of soil decomposer and vegetation communities to stump harvesting in boreal forests

2011

Recently, in addition to logging residues, stumps have become an important component in energy production since there is growing global interest in the use of renewable energy sources in order to decrease anthropogenic carbon emissions. Harvesting of stumps influences the forest floor by changing vegetation and soil organic layers and exposing mineral soil across large areas. We studied whether stump harvesting after clear felling poses further short-term changes in boreal forest soil decomposer community (microbes and mesofauna) and vegetation when compared to the traditional site preparation practice (mounding). In general, stump harvesting caused decline in enchytraeid abundance but did …

Fundusz Medyczny - organizacja i zasady gospodarki finansowej

2021

Celem artykułu jest analiza przepisów normujących organizację i zasady gospodarki finansowej Funduszu Medycznego w kontekście funkcji, jakie w doktrynie prawa finansowego przypisuje się funduszom celowym. W pierwszej części opracowania poddano ocenie regulacje dotyczące organizacji i zadań tej jednostki. Drugą poświęcono przedstawieniu źródeł finansowania oraz zasad gospodarki finansowej Funduszu, zwracając szczególną uwagę na problem zasilania tej jednostki tzw. wpłatą z budżetu państwa. Z uwagi na ograniczone ramy artykułu do odrębnego opracowania pozostawiono problematykę programów inwestycyjnych oraz kwestię trybu i zasad przekazywania środków z Funduszu. Stosując metody właściwe współc…

Le «31 biblioteche più belle del mondo». Dalla Real Biblioteca del Monasterio de San Lorenzo de El Escorial di Madrid al trasferimento, nella nuova s…

2021

Gabriella De Marco propone un saggio sulla centralità dell'istituzione biblioteca nella società contemporanea. Il contributo, che prosegue alcuni precedenti progetti di ricerca avviati dall'autrice sin dai primi anni duemila, è centrato sullo spazio abitabile e sul potenziale identitario di un edificio. Punto di partenza del suo ragionamento è il presupposto che lo spazio misurabile è anche spazio mentale. Ciò attiva una serie di considerazioni legate al rapporto tra il tempo della storia e il tempo del fruitore. Un edificio, pertanto, e nello specifico una biblioteca sia pubblica o privata sia nazionale o di quartiere, si percepisce ed esiste anche nel tempo soggettivo di chi la fruisce.

Weak warning signals can persist in the absence of gene flow.

2019

Significance With our comprehensive set of field (model survival), laboratory (controlled learning, palatability, toxin analysis), and molecular data, we provide evidence that polymorphism can persist in an aposematic population, despite expectations of positive frequency-dependent selection. We show that this can happen if prey species carrying a strong signal can exploit predator learning to elicit broad avoidance of many signals, even if predators only have experience with a single signal. This could allow novel signals to be protected within a population of aposematic prey. Thus, under the expectations of broad generalization coupled with limited gene flow, weak aposematic signals can p…

NT3/TrkC pathway modulates the expression of UCP-1 and adipocyte size in human and murine adipose tissue

2020

ABSTRACTNT3, through activation of its tropomyosin-related kinase receptor C (TrkC), modulates neuronal survival and neural stem cell differentiation. It is widely distributed in peripheral tissues (specially vessels and pancreas) and this ubiquitous pattern suggests a role for NT3, outside the nervous system and related to metabolic functions. The presence of the NT3/TrkC pathway in the adipose tissue (AT) has never been investigated. Present work studies in human and murine adipose tissue (AT) the presence of elements of the NT3/TrkC pathway and its role on lipolysis and adipocyte differentiation. qRT-PCR and immunoblot indicate that NT3 was present in human retroperitoneal AT and decreas…
