Partie polityczne a proces zmian ideologicznych - ujęcie teoretyczne

2018

Celem artykułu jest przedstawienie i omówienie pięciu modeli teoretycznych wyjaśniających problem zmian ideologicznych. Praca ma rzucić światło na dynamiczny charakter ideologii, a także procesualność konstruowania ideologii w środowisku partii politycznych. W pracy zostaną omówione uwarunkowania sprzyjające implementowaniu zmian ideologicznych. Hipoteza przyjęta w niniejszym artykule zakłada, że ideologie partyjne są dynamicznymi konstruktami, podlegającymi korektom w związku ze zmieniającymi się uwarunkowaniami rywalizacji międzypartyjnej.

Density Decline in a Mediterranean Seahorse Population: Natural Fluctuations or New Emerging Threats?

2021

Illegal wildlife trade is considered one of the most serious threats to biodiversity worldwide, along with habitat loss/degradation and overfishing of wild stocks. Seahorses are considered at high risk as these fish represent an important component of traditional Chinese medicine but are also sold as curios and ornamental fish. On a worldwide level, illegal trade is controlled by numerous laws and regulations, but it seems to continue by assuming more dynamic routes. In the Mediterranean Sea, Hippocampus guttulatus formed one of the largest populations at Mar Piccolo di Taranto in South-Eastern Italy. During the routine monitoring of this population in 2016, a dramatic density decrease was …

Global Climate Policies, Local Institutions and Food Security in a Pastoral Society in Ethiopia

2020

This paper explores climate change adaptation within national policy priorities in a least developed country (LDC). The premise of the article is that when considering food security, climate is an exogenous trigger, while the deeper causes lie in social problems. Therefore, adaptation is subordinate to poverty alleviation. The paper examines how these two goals, climate adaptation and poverty alleviation, can be combined. Recent studies have shown that the most effective way to adapt to changing climate conditions in a poor country is to rely on local institutions that have established and sustainable mechanisms to deal with extreme climatic conditions. This research analyzes the stakeholde…

The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…

2004

One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…

Trade And Environment: A Historical Perspective

2015

Abstract The relation between international trade and environmental and social issues has deep historical roots, having been manifest ever since the first industrial revolution. Ironically, the expansion of industrial activities marked, besides the exit from economic backwardness, the commencement of an inexorable war of men against nature. Concomitantly industrialization laid the groundwork for an explosive increase in international trade, which made the latter responsible for increasing environment degradation and social rights infringement. The removal of trade barriers in the first decades after the Second World War as well as the subsequent regulation induced by globalization rendered …

Ecological Functions in the City. Green Infraestructure In Vitoria-Gasteiz

2015

Negli anni recenti, la pianificazione ha cominciato a fare uso di una sorta di razionalità ecologica, nel disegnare le città, che ha portato all’introduzione di misure volte ad accogliere le funzioni naturali nell’ambiente urbano. Da questo punto di vista, Vitoria-Gasteiz nei Paesi Baschi (Spagna) spicca per aver cercato molto a lungo, nella sua storia, di instaurare una relazione equilibrata fra la città e il suo contesto ambientale. Il caso ha ottenuto notorietà internazionale nel 2012, quando la città è stata premiata come “European Green Capital”. Oltre a questa riconosciuta esperienza, a renderla unica è la sua posizione geografica nel Sud dell’Europa, lontano dagli esempi più noti dei…
