The effects of grazing history, soil properties and stand structure on the communities of saprotrophic fungi in wood-pastures

2022

Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect of management, grazing intensity, time since abandonment, historical land-use intensity, soil properties and stand conditions on communities of saprotrophic fungi in wood-pastures in Central Finland. We found that the proportion of broadleaved trees and soil pH are the major drivers in the communities of saprotrophic fungi in these boreal wood-pastures. In addition, tree species richness, soil moisture, historical land-use intensity and time since abandonment affected the communities of saprotrophic fungi. Current management or grazing intensity did not have…

Análisis de los antecedentes histórico-filosóficos de la "paradoja cognitiva de Duval"

2015

In a famous article published in 1993, Raymond Duval highlighted a simple fact: the student may confuse the mathematical object O he is trying to build cognitively with one of its semiotic representations R(O). Duval explained that this confusion was due to a sort of inevitable paradox: only someone who has already built O, can recognize R(O) as a representation of O and not as an object in itself. Thereafter, this thought has been extremely influential for researchers. However, even if in different terms, many scholars of semiotics have emphasized the same phenomenon. In this paper we propose to remind some of them. En un famoso artículo publicado en 1993, Raymond Duval evidenciaba el sigu…

Bcl-xL as a Modulator of Senescence and Aging

2021

Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…

Consensus nomenclature for CD8(+) T cell phenotypes in cancer

2015

International audience; Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T…

Zagadnienia teologiczne sakramentu namaszczenia chorych

2016

Z bogatego zakresu problematyki teologicznej nowej liturgii obrzędów sakramentu namaszczenia chorych, zwłaszcza zawartej we wprowadzeniu teologiczno-pastoralnym, w czytaniach biblijnych i tekstach euchologijnych, autor szerzej omawia jedynie zagadnienia podstawowe. Należą do nich: wymiar chrystologiczny i paschalny sakramentu namaszczenia chorych; umacniająca rola Ducha Świętego w życiu chorego; wymiar eklezjalny tego sakramentu. W sposób skrótowy zasygnalizowano jeszcze takie zagadnienia teologiczno-pastoralne, jak: wymiar pokutny sakramentu namaszczenia; sens choroby w ujęciu teologicznym; potrzeba wprowadzenia nadzwyczajnego szafarza (np. diakona stałego); problem udzielania tego sakrame…

A Process-Oriented View of Procedural Memory Can Help Better Understand Tourette’s Syndrome

2021

Tourette’s syndrome (TS) is a neurodevelopmental disorder characterized by repetitive movements and vocalizations, also known as tics. The phenomenology of tics and the underlying neurobiology of the disorder have suggested that the altered functioning of the procedural memory system might contribute to its etiology. However, contrary to the robust findings of impaired procedural memory in neurodevelopmental disorders of language, results from TS have been somewhat mixed. We review the previous studies in the field and note that they have reported normal, impaired, and even enhanced procedural performance. These mixed findings may be at least partially be explained by the diversity of the s…

Utilitarian Use of Social Media Services - A Study on Twitter

2018

This paper applies structuration theory (ST) and service dominant logic (SDL) as lenses to study different uses of information systems (IS). We argue that resources provided by IS may be combined and reproduced by appropriating them for different purposes than the design purposes of the IS. The study provides empirical data and analysis to showcase the use of resources for utilitarian purposes in the context of social media services (SMS). Through an analysis of sponsored tweets on Twitter, we show that users employ implicit and explicit resources for utilitarian outcomes. Our findings imply that users create their own service through appropriation of resources available in the social conte…

Managing Continuous Digital Service Innovation for Value Co-Creation

2023

Service organizations across various industries are increasingly implementing continuous development methods and practices to transform their digital service innovation and development processes. Consequently, continuous digital service innovation (DSI) has become a way to react to today’s dynamic markets by proposing value to customers quickly while maintaining service quality. However, little is known about how organizations can enable value co-creation (VCC) in their continuous DSI processes. We fill this gap in the literature by focusing on organizational-level continuous DSI processes. Based on findings from 23 industry informants from six Finnish digital service organizations, we pres…
