Cyberbullying has emerged as a major issue across societies and for schools, parents, children, and national governments (see Smith and Steffgen, 2013). Despite some similarities with traditional, or face-to-face (f2f) bullying (Mc Guckin, Cummins and Lewis, 2010), there is sufficient difference to warrant this contemporary and detailed examination of the issues related to cyberbullying—from a perspective that draws upon the most pertinent research and informed opinion from key researchers and thinkers from across the globe. The initial and pioneering knowledge about cyberbullying has now moved to a newer, more mature position that has been able to delineate the nuances associated with the issue, and importantly, yield robust insights for those involved in, or tasked to deal with, cyberbullying.This Special Issue brings together a collection of papers that represents the most up-to-date perspectives and evidence from across the globe. Collectively, these papers demonstrate how scholars and policy makers, from disparate disciplinary or stakeholder starting points, are progressing in their understanding of each other’s language and requirements—thus facilitating the important move towards a more coherent and understandable agenda that seeks to minimize the potential risks to children and young people, understand the relationships between involvement in cyberbullying and associated biopsychosocial factors, in order to implement integrated and evidence-informed intervention and prevention programmes.

Reactive oxygen species (ROS) are inevitable by-products of aerobic cells. A delicate balance between ROS production and antioxidant defences is essential to assure cell function. This requirement is also true for the spermatozoon, the male gamete, with the unique goal of carrying and delivering the paternal genome into the oocyte. Oxidative stress promotes damage in lipids, proteins and DNA of spermatozoa, and this oxidative damage is associated with infertility. The ROS-dependent damage could occur at different stages of the production and maturation of the sperm. On the other hand, low and controlled levels of ROS are necessary to trigger and regulate sperm function. When ejaculated, spermatozoa are incapable of fertilizing the egg. They must reside in the oviduct of the female genital tract to undergo a yet to be understood the biochemical process called capacitation. Once capacitated, the spermatozoon undergoes the exocytotic event called acrosome reaction and fertilize the oocyte. ROS regulate the different molecular mechanisms such as sperm motility, capacitation and acrosome reaction to assure fertilization. This Special Issue includes original research and reviews of literature concerning the role of reactive oxygen species in male reproduction, particularly the role of antioxidants in the regulation of male fertility as well as basic and clinical studies using antioxidant-based strategies for the treatment of male infertility.

Nanobodies have become outstanding tools for biomedical research, diagnostics and therapy. Recent advances in the identification and functionalization of target-specific nanobodies now make nanobody-based approaches broadly available to many researches in the field. This book provides a compilation of original research articles and comprehensive reviews covering important and up to date aspects of research on nanobodies and their applications for immunoassays, proteomics, protein crystallization and in vitro and in vivo imaging.

Dieses Buch behandelt die Frage, wie mit Blick auf die Veränderungen des Arbeitsmarktes die Erwerbstätigkeit von Frauen und Älteren erleichtert werden kann. Die demographische Entwicklung führt dazu, daß das durchschnittliche Alter der Arbeitskräfte steigt und sich das Arbeitskräftepotential zukünftig verkleinern wird. Andererseits verschieben sich die Arbeitsanforderungen durch die Nutzung moderner Produktions- und Organisationsmethoden. In einer mikroökonomisch und arbeitswissenschaftlich ausgerichteten Analyse werden Maßnahmen der Arbeitsgestaltung und der Personalentwicklung entworfen und beurteilt, die zur Erhöhung der Frauenerwerbstätigkeit und zur Verlängerung der Lebensarbeitszeit beitragen können.

not yet availableDie Bedeutung des Körpers in der Kultur des Mittelalters ist in den letzten Jahren immer wieder ins Zentrum der Forschung gerückt — ebenso wie Fragen nach dem Einfluss von Wahrnehmungsmechanismen und -vorgängen auf die Literatur und Kunst dieser Zeit. Dass beide Forschungsgebiete eng zusammen gehören, wird bereits durch die antiken Rhetoriken, in denen der deformierten Körperlichkeit eine besondere wahrnehmungsstimulierende Funktion zugesprochen wird, gestützt. Auch das komplizierte und immer wieder kontrovers diskutierte Wechselverhältnis von ‚Innen‘ und ‚Außen‘, deutet darauf hin, dass insbesondere der deformierte Körper bestimmte Erwartungen bezüglich des zugehörigen Inneren weckt, zugleich aber auch bei einem Betrachter dieses deformierten Körpers sehr spezifische Wahrnehmungsvorgänge auslöst. Neben Körper und Wahrnehmung wird so ein Drittes sichtbar — das Andere, einmal verstanden als das Fremde, das in der Betrachtung und Reflexion der halbvertrauten Deformation aufscheint, einmal als das Ur-Eigene, die Seele selbst, als das Komplement der korrumpierten Hülle. Der Band (ebenso wie der Folgeband) vereint dabei nicht nur literaturwissenschaftliche und kunstgeschichtliche Beiträge, sondern schlägt zugleich die Brücke zur Medizingeschichte, zu den Dis/ability Studies u. ä., um so zu zeigen, dass nicht nur der künstlich-künstlerisch entworfene, sondern auch der ‚reale‘ deformierte Körper erst in seinem Verhältnis zu den Wahrnehmungstheorien seiner Zeit zu verstehen ist.

Sustainable agriculture aims to achieve the goal of food security, also maximizing the socio-economic benefits, and minimizing environmental drawbacks. Farming systems mostly relying on ecological processes and the reduced application of external inputs (fertilizers and pesticides), such as organic farming and integrated farming, can even contribute to the mitigation of global warming and of the desertification of soils. Conservation agriculture (CA) is also widely recognized as a farming system able to preserve soils from erosion and nutrient loss, increase soil organic matter and carbon sink capacity, and improve biological and physical fertility. Nevertheless, CA systems generally rely on the large use of agrochemicals (above all, herbicides and fertilizers) in order to sustain crop production, with negative consequences in terms of energy efficiency and environmental impact. This also does not enable an easy transfer of CA techniques into organic and integrated farming systems, a combination that might enhance the environmental benefits of these farming systems. In this regard, this Special Issue deals with the "Smart Management of Conservative, Organic, and Integrated Agriculture". We invited experts and researchers to contribute with original researches, reviews, and opinion pieces covering all topics related to organic, integrated, and conservative farming systems. The published articles concern with the most important aspects of these innovative systems, such as performances of farm machinery and agro-ecological strategies aiming at sustaining crop production whilst reducing the need for agrochemicals.

"La Mediocridad como Sagrado" La región se viste de inocencia como un mendigo viste harapos: con la certeza de que nadie cuestionará el olor a podrido bajo la tela. Aquí, la mediocridad no es fracaso; es ritual. Se celebra en cada silencio cómplice ante los cuerpos anónimos en las carreteras, en cada risa nerviosa que sigue a la noticia del auto destrozado de algún funcionario. Nadie pregunta por qué. Nadie puede preguntar. Porque cuestionar sería romper el pacto: el pacto de que, mientras el f

This book offers the first attempt at understanding interpersonal violence in ancient Athens. While the archaic desire for revenge persisted into the classical period, it was channeled by the civil discourse of the democracy. Forensic speeches, curse tablets, and comedy display a remarkable openness regarding the definition of violence. But in daily life, Athenians had to draw the line between acceptable and unacceptable behavior. They did so by enacting a discourse on violence in the performance of these genres, during which complex negotiations about the legitimacy of violence took place. Since discourse and reality were intertwined and the discourse was ritualized, actual violence might also have been partly ritualized. By still respecting the on-going desire to harm one's enemy, this partial ritualization of violence helped restrain violence and thus contributed to Athens' relative stability.
