Cultural activities of young adults in urban time-space: The case of Paleo Phaliro in Athens.

The basic aim of this research is to uncover the role of cultural activities, especially those related to music and cinema, situated in the urban time-space, in the quest for identity by young adults (aged 19-25) as it is expressed in their life-style. The fieldwork area is the locality of Paleo Phaliro in Athens which is a middle-class area of low concentration of cultural spaces especially in comparison to the nearby city centre. The conceptual framework introduces elements of cultural studies and social anthropology into cultural geography focusing on the agency - structure interrelationship. The direct type of connection between theory and fieldwork, mainly expressed through differentiations (contradictions), led to an emphasis on qualitative analysis, and particularly to the use of multiple case studies which was methodologically translated into structured indepth interviews and semi-structured diaries. The perceptions and actions of young adults show that common elements exist, which, although they focus on consumption and on the individual, also involve active participation in groups. Their musical and cinematic preferences show a tendency towards the global, which co-exists with an attachment to the locality. Their life-attitudes indicate a rejection of routinisation that constitutes the basis of the reaction to a stereotype of action, which is mainly imposed by the media, and secondarily by the family and the school. This contradictory process, which is situated in a context of plurality of times, spaces and cultures, also involves a plurality of cultural identities. The attitudes of the present are important for the future, especially for young adults in an area, and a city, with an ageing population. The primacy of music, in a global world where the impact of artistic activities is slowly recognised, is a factor of hope regarding the cultural aspect of the European unification

Local anesthesia in piglets undergoing castration-A comparative study to investigate the analgesic effects of four local anesthetics on the basis of acute physiological responses and limb movements

Surgical castration of male piglets without analgesia is a painful procedure. This prospective, randomized and double-blinded study aimed to evaluate the analgesic effects of four different local anesthetics for piglet castration during the first week of life. In total, 54 piglets aged 3 to 7 days were distributed into 6 treatment groups: handling (H);castration without pain relief (sodium chloride, NaCl);and castration with a local anesthetic: 4% procaine (P), 2% lidocaine (L), 0.5% bupivacaine (B) or 20 mg/ml mepivacaine (M). By excluding stress and fear as disruptive factors via a minimum anesthesia model, all piglets received individual minimum alveolar concentration (MAC) isoflurane anesthesia. Twenty minutes before castration, all treatment groups except group H received one injection per testis. Then, 0.5 ml of a local anesthetic or NaCl was injected intratesticularly (i.t.), and 0.5 ml was administered subscrotally. Acute physiological responses to noxious stimuli at injection and castration were evaluated by measuring blood pressure (BP), heart rate (HR), cortisol, epinephrine, norepinephrine and chromogranin A (CgA);limb movements were quantified. The results confirm that castration without analgesia is highly painful. Surgical castration without pain relief revealed significant changes in mean arterial blood pressure (MAP) and HR. Local anesthetic administration significantly reduced changes in BP and HR associated with castration. Piglets receiving a preoperative local anesthetic exhibited the fewest limb movements during castration, while the NaCl group exhibited the most. Injection itself was not associated with significant changes in MAP or HR. However, many piglets exhibited limb movements during injection, indicating that the injection itself causes nociceptive pain. No significant differences were found between groups regarding parameters of plasma cortisol, catecholamines and CgA. In conclusion, all four local anesthetics administered are highly effective at reducing signs of nociception during castration under light isoflurane anesthesia. However, injection of a local anesthetic seems to be painful

Current vortices in aromatic carbon molecules

The local current flow through three small aromatic carbon molecules, namely benzene, naphthalene and anthracene, is studied. Applying density functional theory and the non-equilibrium Green's function method for transport, we demonstrate that pronounced current vortices exist at certain electron energies for these molecules. The intensity of these circular currents, which appear not only at the anti-resonances of the transmission but also in vicinity of its maxima, can exceed the total current flowing through the molecular junction and generate considerable magnetic fields. The $\pi$ electron system of the molecular junctions is emulated experimentally by a network of macroscopic microwave resonators. The local current flows in these experiments confirm the existence of current vortices as a robust property of ring structures. The circular currents can be understood in terms of a simple nearest-neighbor tight-binding H\"uckel model. Current vortices are caused by the interplay of the complex eigenstates of the open system which have energies close-by the considered electron energy. Degeneracies, as observed in benzene and anthracene, can thus generate strong circular currents, but also non-degenerate systems like naphthalene exhibit current vortices. Small imperfections and perturbations can couple otherwise uncoupled states and induce circular currents

Comparing journalism cultures in Britain and Germany: confrontation, contextualization, conformity

Many British newspapers proclaim strongly partisan political and moral positions, with headlines such as ?Get Britain out of the EU.? In contrast, German newspapers, during national events such as the refugee crisis, often take on the role of reflective observers. Previous comparative research has shown a link between journalists? output and professional attitudes. Using data from the Worlds of Journalism Study, this article analyses the professional attitudes of British and German journalists (N=1475) across three constituents of journalism culture: societal, epistemological, and ethical. Our analysis shows significant differences in all three constituents. We conclude that British journalists conceive of their professional role as more confrontational to those in power than their German colleagues. We also find some evidence that German journalists believe it more important to provide context and analysis ? aiming to assist audiences in their civic roles ? and that they are more likely to conform to professional codes, although only in general terms. Our findings contradict some earlier comparative studies that claimed a more passive role for British journalists. Our findings may also hold interest for others engaged in international comparative research, showing how the two-country comparison can identify, and account for, what is hidden in multi-country research designs

The Limits of Inelastic Tunneling Spectroscopy for Identifying Transport Pathways

Inelastic Electron Tunneling Spectroscopy (IETS) is a powerful tool to study the properties of molecular junctions. In particular, it is considered useful for extracting information on electron transport pathways. We explore the limits of this approach by comparing computed interatomic transmission pathways with IETS intensities for different molecular junctions, employing a new efficient implementation for evaluating IETS intensities via the mode-tracking algorithm. We find that while a correlation be- tween pathways and IETS intensities indeed holds when vibrations are clearly localized on atoms off the transport pathway, there is no such correlation for molecules with less localized vibrations, even if transport pathways only sample part of the molecule, and even if a statistical analysis over the vibrational modes is made. This could indicate that the significance of IETS signals for transport pathways is limited to molecules with localized vibrational modes
