Predicting invasion potential has global signifi cance for managing ecosystems as well as important theoretical implications for understanding community assembly. Phylogenetic relationships of introduced species to the extant community may be predictive of establishment success because of the opposing forces of competition/shared enemies (which should limit invasions by close relatives) versus ...

Purpose – The purpose of this paper is to explore the relationship between transformational leadership and a transactional leadership component (management by exception-active), and fulfillment of the basic needs of autonomy, competence and relatedness. Design/methodology/approach – The paper is based on cross sectional data from 661 employees who completed validated questionnaires such as the ...

Theory of human relatedness addresses a pervasive human concern, establishing and maintaining relatedness to others, objects, environments, society and self. This theory, derived from a series of inductive and deductive strategies, views relatedness as a functional, behavioral system rooted in early attachment behaviors. Individuals move through different states of relatedness including connect...

All over the world, educational science outreach programs in which students can perform laboratory work have been developed. A common goal of these is to counteract students' decreasing motivation STEM education. In Germany, several labs established last 20 years. It assumed that characteristics foster basic need satisfaction and qualities such as intrinsic flow. However, research this field of...

Kin selection predicts that helpers in cooperative systems should preferentially aid relatives to maximize fitness. In family-based groups, this can be accomplished simply by assisting all group members. In more complex societies, where large numbers of kin and non-kin regularly interact, more sophisticated kin-recognition mechanisms are needed. Bell miners (Manorina melanophrys) are just such ...

BACKGROUND Clinicians who perform radiation therapy (RT) are exposed to radiation, which may negatively affect their health. The present study reports a case of acute lymphoblastic leukemia in a healthcare provider who was exposed to radiation at work; we also present a literature review of this topic. CASE PRESENTATION A 45-year-old patient, who had been a radiation oncologist and had been e...

BACKGROUND Although non-specific low back pain (LBP) is known to be multifactorial, studies from across the globe have documented their higher prevalence in nurses. This systematic review was conducted to ascertain whether this much-documented association constitutes a causal relationship, and whether there is a discernible threshold of exposures associated with this elevated risk. METHODS PR...

Processing time and memory for sentences were examined as a function of the degree of semantic and causal relatedness between sentences in short narratives. In Experiments 1–2B, semantic and causal relatedness between sentence pairs was independently manipulated. Causal relatedness was assessed through pretesting and semantic relatedness was assessed with Latent Semantic Analysis. Causal relate...
