Approaching electrical tomography

2009

A general approach to electrical tomography is here described, based on the distribution of the experimental data to the set of voxels in which the subsoil has been divided. This approach utilizes the sensitivity coefficients as factors of the convolution procedure to execute the back projection of the data, to obtain the 3D pictures of the subsoil. A subsequent probabilistic filtering technique is described to improve the pictures in view of sharp boundary models. Some models are finally presented, mostly regarding cubic buried anomalies as well as pipe-shaped and L-shaped anomalies.

Retention forestry and biodiversity conservation: a parallel with agroforestry

2013

In forested landscapes two general management systems – retention forestry and agroforestry – have been proposed as potentially efficient components of landscape approaches to ease the conflict between biodiversity objectives and human needs. In two recent reviews, Gustafsson et al. (2012) and Lindenmayer et al. (2012) provide a global overview of current knowledge about the practice and ecological roles of retention forestry. A few years ago, Bhagwat et al. (2008) produced a similar review addressing the role of agroforestry in biodiversity conservation. Here we draw a parallel between research on the ecological effects of retention forestry and agroforestry. We argue that conservation sci…

First report of an olive ridley (Lepidochelys olivacea) inside the Mediterranean Sea

2015

We report the first confirmed occurrence of a Lepidochelys olivacea in the Mediterranean Sea based on the study of an individual stranded on a beach, located in the town of Oropesa del Mar (40º05ʹ32ʺN, 0º08ʹ02ʺE), Castellón province, East Spain, in May 2014. Morphological and genetic analyses were used to confirm the identification of the species. The individual had a sequence that matched the 470 bp Lepidochelys olivacea haplotype F (Genbank accession number: AF051773), found in several Atlantic populations. This becomes one of the northernmost known occurrences of olive ridleys in the world and is the first reports of this species in the Mediterranean Sea.

Carbon emissions by Ssouth american companies: driving factors for reporting decisions and emissions reduction

2018

In the last decade, companies have started to disclose information on carbon emissions. To our knowledge, this is the first paper to look into this phenomenon in South America, which is a very important geographical area regarding climate change because of the local nature and developing economies. This paper explores the relationships between some corporate variables and two important decisions: (i) whether to report carbon emissions, and (ii) the impact on the evolution of carbon emissions. Logit and linear panel data models are used to determine the driving factors for decisions (i) and (ii). Our results show that regarding the carbon reporting decision, a company&rsquo

LMX and Well-Being: Psychological Climates as Moderators of their Concurrent and Lagged Relationships

2020

The importance of the quality of leader member exchange (LMX) for workers’ health and well-being is acknowledged in the literature, and empirical research addressing this issue is beginning to accumulate. However, recent reviews on this topic recommend making a greater effort to include time and boundary conditions in this relationship. The present study aims to analyze the effects of LMX on employees’ well-being, and the moderating role of psychological climate, by means of a longitudinal study with a 12-month time lag. Data were obtained from 119 employees working in the Public Health Service . Results show that LMX had concurrent and lagged positive effects on well-being. Perceptions of …

”Juhannuksena sää saattaa olla lämmin” : Mitä sanomalehtien sääkirjoitukset kertovat suomalaisten suhteesta säähän ja ilmastoon?

2020

Ilmasto konkretisoituu ihmisten arkeen sään kautta; ilmaston merkitys välittyy sään kokemisessa ja säälle annetuissa paikallisissa merkityksissä. Näin sään ja sille annettujen kulttuuristen merkitysten tutkiminen tuo arvokkaan lisän ilmastonmuutoksen arkisten seurausten hahmottamisessa ja voi auttaa ymmärtämään erilaisia ilmastonmuutosnäkemyksiä ja näistä juontuvia ilmastopolitiikan konflikteja. Tämän vuoksi kiinnostus arkisten sääkokemusten tutkimukseen on kasvanut viime vuosina. Artikkeli tarjoaa katsauksen tähän kansainvälisesti kehittyvään kulttuurisen ilmastotutkimuksen kenttään, sekä tarkastelee empiirisesti sään kulttuurisia merkityksiä Suomessa sanomalehtiaineiston avulla. Empiirine…

An eco-label for the airline industry : instrument for behavioral change?

2017

Climate change is the biggest challenge humanity has ever faced and there is no doubt that human activities are the main cause. One activity that has received much attention in this discussion is air transportation. Although its contribution is still moderate, this industry is growing at a very fast rate and with that its impact on climate change. In order to enjoy its social and economic benefits also in the future and to avoid regulatory restrictions, the industry’s contribution needs to be kept in check. Various mitigation strategies exist such as technological, market-based, operational, regulatory and behavioral changes. This dissertation focuses on behavioral change. One instrument le…

Empirical links between natural mortality and recovery in marine fishes

2017

Probability of species recovery is thought to be correlated with specific aspects of organismal life history, such as age at maturity and longevity, and how these affect rates of natural mortality ( M ) and maximum per capita population growth ( r max ). Despite strong theoretical underpinnings, these correlates have been based on predicted rather than realized population trajectories following threat mitigation. Here, we examine the level of empirical support for postulated links between a suite of life-history traits (related to maturity, age, size and growth) and recovery in marine fishes. Following threat mitigation (medium time since cessation of overfishing = 20 years), 71% of 55 tem…
