The identity of the tropical African Polichne mukonja Griffini, 1908 (Orthoptera, Tettigoniidae, Phaneropterinae)
2016
Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both taxa are p…
The legacy of human use in Amazonian palm communities along environmental and accessibility gradients
2023
Aim: Palms are iconic and dominant elements of neotropical forests. In the Amazon region, palms have been used and managed by humans for food, material, medicine and other purposes for millennia. It is, however, debated to what extent the structure of modern palm communities reflects long-term human modification. Here, we investigate the complex interplay of ecological and societal factors that influence the distributions of both human-used and non-used palms in western Amazonia. Location: Amazonia. Time period: Present. Major taxa studied: Palms (Arecaceae). Methods: We used Bayesian hierarchical joint species distribution models to predict the distributions and environmental niche dimensi…
Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection
2021
At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…
Depressive symptoms and long-term income: The Young Finns Study
2016
Abstract Background Higher depressive symptoms have been associated with lower future income. However, studies examining this issue have had limited follow-up times and have used self-reported measures of income. Also, possible confounders or mediators have not been accounted. Methods 971 women and 738 men were selected from the ongoing prospective Young Finns Study (YFS) that began in 1980. Depressive symptoms were measured in 1992 when participants were from 15 to 30 years old. Information on annual income and earnings from 1993 to 2010 were obtained from the Finnish Longitudinal Employer-Employee Data (FLEED) of Statistics Finland and linked to the YFS. Results Higher depressive symptoms…

Employee personal Internet usage in the workplace
2016
Information technology (IT) devices connected to the Internet, such as computers, tablets, and smartphones, have become pervasive in the workplace. These IT devices have greatly facilitated the performance of job tasks for employees. At the same time, employees are increasingly using these technologies for non-work-related purposes during office hours, which is called personal Internet usage in the workplace (PIU). Examples of PIU include, but are not limited to, checking and sending non-work-related emails, surfing news sites, visiting social network sites, e-banking, stock trading, and online shopping, chatting, and gaming. Previous studies on PIU present two schools of thought on PIU out…

Valoración de las necesidades de información de los médicos: publicaciones en el periodo 1990-1998 y estudio de un caso
2000
Los estudios de necesidades de información aportan una metodología con lo cual investigar, de manera sistemática, las características de los usuarios con relación a la información que necesitan para el desarrollo de su trabajo. Igualmente proporcionan criterios objetivos para tomar decisiones a la hora de planificar nuevos sistemas de información o adecuar los ya existentes. Esta tesis ha profundizado en los estudios de necesidades de información en el entorno hospitalario desde dos puntos de vista. Por una parte, se ha establecido un marco teórico de referencia que guíe las investigaciones en este campo. Para ello se ha buscado exhaustivamente la información publicada sobre la materia apor…
Experimental Evolution Reveals a Genetic Basis for Membrane-Associated Virus Release
2021
Many animal viruses replicate and are released from cells in close association to membranes. However, whether this is a passive process or is controlled by the virus remains poorly understood. Importantly, the genetic basis and evolvability of membrane-associated viral shedding have not been investigated. To address this, we performed a directed evolution experiment using coxsackievirus B3, a model enterovirus, in which we repeatedly selected the free-virion or the fast-sedimenting membrane-associated viral subpopulations. The virus responded to this selection regime by reproducibly fixing a series of mutations that altered the extent of membrane-associated viral shedding, as revealed by fu…
On the dynamics of disobedience: experimental investigations of defying unjust authority.
2017
Across six Experimental conditions with university student participants (N=600), we examined some of the dynamics underlying expressed defiance to unjust authority. Results revealed disobedience was best enacted by participants low in right-wing authoritarianism and was more likely to occur when: 1) in physical proximity of other rebels, 2) the authority made two demanding requests instead of one, and 3) there had been an earlier opposition to injustice. Results are discussed within the theoretical framework of bounded rationality.
