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

L'esperienza formativa come opportunità di apprendimento organizzativo per la scuola

2012

What are the most appropriate ways to activate changes in educational services in order to optimally answer to their institutional mandate in a complex society? This paper answers this question by adopting a organizational perspective that covers interconnected and coordinated learning processes, with all the actors of the educational system (pupils, teachers, parents, managers, administrative staff...) and, in a meta-level, of the system itself. After an excursus on the theories of the organization, useful information for making choices and conscious operational design in a systemic and ecological perspective are given.

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 …

Un modelo basado en el clima laboral de Indicadores del desempeño directivo en la perspectiva de aprendizaje y crecimiento

2006

Kaplan y Norton, (1996) introducen en los Cuadros de Mando de las empresas la perspectiva estratégica de aprendizaje y crecimiento de la organización. Este enfoque se basa en los ciclos de aprendizaje directivo de Argyris y Schön (1974) y, según los propios autores, es una perspectiva emergente aún por desarrollar (Kaplan, 1998) El propósito de este trabajo es fundamentar, elaborar y verificar empíricamente un modelo que, a partir del análisis del Clima laboral, permita obtener feed-back del desempeño directivo en materia de prácticas y políticas de motivación de los recursos humanos. Las políticas de RR HH son herramientas clave para la construcción de capacidades (Losey et al., 2005), las…

”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…

Palladium-Catalyzed Direct Arylation of Heteroaromatics with Activated Aryl Chlorides Using a Sterically Relieved Ferrocenyl-Diphosphane

2012

International audience; The palladium-catalyzed direct arylations at C3 or C4 positions of heteroaromatics are known to be more challenging than at C2 or C5 positions. Aryl chlorides are also challenging substrates for direct arylation of heteroaromatics. We observed that in the presence of a palladium-catalyst combining only 0.5 mol % of Pd(OAc)2 with the sterically relieved new ferrocenyl diphosphane Sylphos, the direct arylation at C3 or C4 of oxazoles, a benzofuran, an indole, and a pyrazole was found to proceed in moderate to high yields using a variety of electron deficient aryl chlorides. Turnover numbers up to 176 have been obtained with this catalyst. Assessment of the electron-don…
