Buffer strips can pre-empt extinction debt in boreal streamside habitats

2013

Background. Conservation of biological diversity and economical utilization of natural resources form an almost inevitable confrontation between the two. In practice, however, a balance between the two ought to be found, and in managed boreal forests, preservation of woodland key habitats is increasingly used strategy to safeguard biological diversity. According to the Finnish Forests Act, certain Forest Act habitat (FAH) types must be safeguarded, provided they are clearly distinguishable from their surroundings. Furthermore, once the habitat has been identified as a FAH, its special characteristics must not be altered. Both of these aspects contain ambiguities that potentially undermine t…

il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi

2014

riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …

Parasite avoidance behaviours in aquatic environments

2018

Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a heavy burden upon host animals. However, hosts are not without defences. One aspect of host defence, behavioural avoidance, has been studied in the terrestrial realm for over 50 years, but was first reported from the aquatic environment approximately 20 years ago. Evidence has mounted on the importance of parasite avoidance behaviours and it is increasingly apparent that there are core similarities in the function and benefit of this defence mechanism between terrestrial and aquatic systems. However, there are also stark differences driven by the unique biotic and abiotic characteristics of terrestrial …

Tietojen kalastelu sosiaalisen median palveluissa

2014

Huusko, Tuija Tietojen kalastelu sosiaalisen median palveluissa Jyväskylä: Jyväskylän yliopisto, 2014, 33 s. Tietojärjestelmätiede, kandidaatintutkielma Ohjaaja: Veijalainen, Jari Tämän kandidaatintutkielman tarkoituksena on tutkia tietojen kalastelun keinoja sosiaalisen median palveluissa sekä menetelmiä, joilla voidaan suojautua tietojen kalastelulta. Sosiaalinen media on valtavan laaja kenttä, johon myös tietojen kalastelijat ovat suunnanneet mielenkiintonsa, ja siihen kohdistetaan samanlaisia hyökkäyksiä kuin muillekin sivustoille. Hyökkäykset aiheuttavat taloudellisia ja henkilökohtaisia vahinkoja riippumatta siitä, mihin sivustoon ne suunnataan. Sosiaalisen median hyödyntäminen on suu…

On algebras and superalgebras with linear codimension growth

2006

We present the classification, up to PI-equivalence, of the algebras over a field of characteristic zero whose sequence of codimensions is linearly bounded. We also describe the generalization of this result in the setting of superalgebras and their graded identities. As a consequence we determine all linear functions describing the ordinary codimensions and the graded codimensions of a given algebra.

The Supranational Dimension in Max Weber’s Vision of Politics

2019

Max Weber analyzed politics from the perspective of Chancen for actors, and he never separated world politics from domestic politics. The “Westphalian balance” between great European powers shaped Weber’s views on international polity. However, he also regarded Western individualism, human rights, and parliamentary democracy as necessary qualities to possess in order to be recognized as a great power. This vision provided the basis for his wartime critique of the expansionist tendencies in German foreign policy and for his demand for the parliamentarization of German politics. After the end of World War I, Weber used Woodrow Wilson’s idea of the League of Nations as the basis for a proposal…

Size-related mortality during overwintering in cavity-nesting ant colonies (Hymenoptera: Formicidae)

2016

The ongoing process of climate change will result in higher temperatures during winter and therefore might increase the survival of overwintering invertebrates. However, the process may also lead to a reduction in snow cover and expose overwintering invertebrates to lower temperatures, which could result in higher mortality. During a field experiment, I investigated the effects of a reduction in snow cover on the survival of the ant Temnothorax crassispinus, which overwinters in nests located on the ground. Ant colonies differed in the survival rate of the workers in the experimental (from which snow cover was removed) and control group. In the control group, the survival rate was unrelated…

Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis

2020

Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
