"Wie sieht die Bilanz der eBay-Selbständigkeit aus und welches Fazit kann im Hinblick auf die Möglichkeiten und Beschränkungen der interviewten Selbstständigen gezogen werden? Die Einschätzung von eBay als Sprungbrett, als neue Möglichkeit, sich kostengünstig und einfach aus dem privaten Kontext heraus selbstständig zu machen, ist positiv zu werten. Indem lohnabhängige, fremdbestimmte Arbeitsverhältnisse durch Selbstständigkeit ersetzt werden können, enstehen für die Interviewten hinsichtlich der selbstbestimmten Gestaltung vonArbeit und Leben, trotz neuer spezifischer (eBay-)Abhängigkeiten und unternehmerischer Risiken, neue Chancen und Freiräume. Kurz, der Weg über eBay in die Selbstständigkeit stellt für die befragten Akteure und Akteurinnen "Empowerment" dar, sie sind ihr eigener Chef bzw. ihre eigene Chefin. Dass sie damit aber auch die perfekte Führungskraft sind, sich selbst am besten zu verwerten und auszubeuten, wurde gerade im Zusammenhang von Arbeitsvolumen und Arbeitszeiten deutlich. Trotz dieser paradoxen Verquickung ziehen alle Interviewten eine eindeutig positive Bilanz. "Wir hoffen, irgendwann mal demnächst soviel Geld damit zu verdienen, dass wir ein bisschen früher nicht mehr arbeiten müssen", erzählten Inga und Tom Finke und setzen ihr aktuelles Zeitmanko damit biographisch in einen größeren Zeit-Zusammenhang. Auch einige an- dere verlegen den jeweils individuell denierten Nutzen all der Anstrengung und Arbeit in die Zukunft, zu einer Art Zielder Lebensbilanz. Frieda und Paul Jenkins drückten das so aus: Wir wollen irgendwann dastehen und sagen, [Firma Jenkins], das hat mal ganz klein angefangen mit einem Ring von Joop, wo jemand kam und gesagt hat, guckt mal auf eBay. Neben diesem an Gründerleitbildern und Unternehmerbiographien orientierten prospektiven "Bilderbuch-Rückblick" als Zukunftswunsch, erfolgte in den Interviews auch eine Zwischenbilanz, ein Rückblick auf bisherige Erfolge. Erfolg ist dabei zwar an den betriebswirtschaftlichen Erfolg des jeweiligen Unternehmens gekoppelt, wird aber hauptsächlich individuell über die positiven Punkte für die gegenwärtige Arbeitssituation de niert: das selbstbestimmte Arbeiten, die (Lern-)Erfahrungen durch die Selbständigkeit, die Möglichkeit, dem individuellen Arbeits- und Lebensentwurf nachgehen zu können....."
Life of Varroa destructor, Anderson and Trueman, an ectoparasitic mite of honeybees, is divided into a reproductive phase in the bee brood and a phoretic phase during which the mite is attached to the adult bee. Phoretic mites leave the colony with workers involved in foraging tasks. Little information is available on the mortality of mites outside the colony. Mites may or not return to the colony as a result of death of the infested foragers, host change by drifting of foragers, or removal of mites outside the colony. That mites do not return to the colony was indicated by substantially higher infestation of outflying workers compared to the infestation of returning workers (Kutschker, 1999). The main objective of the study was to provide information whether V. destructor influences flight behaviour of foragers and consequently returning frequency of foragers to the colony. I first repeated the experiment of Kutschker (1999) examining the infestation of outflying and returning workers. Further, I registered flight duration of foragers using a video method. In this experiment I compared also the infestation and flight duration of bees of different genetic origin, Carnica from Oberursel and bees from Primorsky region. I investigated returning time of workers, returning frequency until evening, drifting to other colonies and orientation toward the nest entrance in the experiments in which workers were released in close vicinity of the colony. At last, I measured the loss of foragers in relation to colony infestation using a Bee Scan. Results from this study, listed below, showed considerable influence of V. destructor on flight behavior of foragers translating into loss of mites. Loss of mites with foragers add substantial component to mite mortality and was underestimated in previous studies. Such loss might be viewed as a mechanism of resistance against V. destructor. a) The mean infestation of outflying workers (0.019±0.018) was twice as the mean infestation of returning workers (0.009±0.018). The difference in the infestation between outflying and returning workers was more marked in highly infested colonies. b) Investigation of individually tagged workers by use of a two camera video recording device showed significantly higher infestation of outflying workers compared to returning workers. Mites were lost by the non returning of infested foragers (22%) and by loss of mites from foragers that returned to the colony without the mite (20%). A small portion of mites (1.8%) was gained. Loss of mites significantly exceeded mite gain. c) The flight duration of infested workers determined by using the same two camera video system was significantly higher in infested compared to uninfested workers of the same age that flew closest at time. The median flight duration of infested workers was 1.7 higher (214s) than the median duration of unifested workers (128s). d) Infested workers took 2.3 times longer to return to the colony than uninfested workers of the same age when released from the same locations, closest at time. The returning time increased with the distance of release. In a group of bees released simultaneously the infestation was higher in bees returning later and in those that did not return in the observation period of 15 min. e) Released workers did not return to the colony 1.5 more frequently than uninfested workers in evening. The difference in returning was significant for locations of 20 and 50m from the colony. No difference in returning between infested and uninfested workers were observed for the most distant location of 400m. f) No significant difference was found in returning time and/or in the returning frequency until evening between workers artificially infested overnight and naturally infested workers. Artificially infested workers returned later and less frequently than a control group indicating rapid influence of V. destructor on flight behavior of foragers. g) The orientation ability of infested workers toward the nest entrance was impaired. Infested workers compared to uninfested workers twice as often approached a dummy entrance before finding the nest entrance. h) No significant differences were found in drifting between infested and uninfested workers. Drifting in the neighboring nucleus colony occurred in about 1% occasions after release of marked workers. Similarly, more infested, but not significantly more infested workers (2.6%) entered a different colored hive than the same colored hive (1.9%). However, the number of drifting bees were to low to make results conclusive. i) The comparison between Carnica and Primorsky workers revealed higher infestation in Carnica compared to Primorsky. Further, Primorsky workers lost more mites during foraging due to mite loss from foragers and non returning of infested workers. No significant differences in flight duration were observed between the two bee stocks. j) Loss of foragers, as determined by the Bee Scan counts of outflying and returning foragers, and the infestation of outflying bees increased significantly over a period of 70 days. A colony with 7.7. higher infestation of outflying foragers lost 2.2. time more bees per flight per day compared to a low infested colony. k) The estimates of mite loss with foragers from mite population per day up to 3.1% exceeds approximately mite mortality of 1% within the colony as represented by counting dead mites on bottom board inserts.

Partial melting of crustal and mantle rocks under pressure from impedance spectroscopy measurements
(2004)
The purpose of this work is to achieve a better understanding of the physical properties of rocks during partial melting processes. The electrical conductivity of some crustal and upper mantle rocks was measured prior and above the melting under pressure. The variations of the electrical conductivity were compared with the distribution of melt in partially molten rock samples. The electrical conductivity was estimated from the impedance spectroscopy at temperatures between 800 and 1450˚C and at pressures between 0.3 and 2 GPa. These measurements were performed in a piston cylinder apparatus. At temperatures above the melting, samples were equilibrated during a long time and subsequently quenched. Thin sections were prepared and topology, volume fraction and chemical composition of melt was analyzed by using a microprobe. Above the solidus temperature, the electrical conductivity increases for about 1 to 2 orders of magnitude in comparison with non-melted rocks. The "melt effect" seems to reflect the formation of an interconnected network of melt. When a complete melt connectivity is established, the charge transport follows the network of the formed melt films at grain boundaries. Usually, it takes a long time in order to reach a steady state of the electrical resistance in partially molten rocks. Only when a steady state of the electrical resistance is achieved, the bulk conductivity of a sample can be measured properly. The time-independent electrical conductivity were found only after 200 h of annealing time at a desired temperature.
Usually, the measurements of a dihedral angle on grain-liquid interfaces in rocks show that the wetting of grain faces start to develop at temperatures slightly above the solidus temperature. The development of these faces should lead to a continuous melt network even at small melt fractions of few wt.%. This result is not confirmed by our electrical conductivity measurements. The complete interconnection of the melt phase, which was mark by an increase of the electrical conductivity, corresponds to a temperature significantly above the solidus temperature, for at least 30-50˚C. The development of these faces stimulate a significant increase of the electrical conductivity, and corresponds to the occurence of at least 5 wt.% of a melt fraction. This result could be explained by deviations from the textural equilibrium of a melt phase topology in partially molten samples due to heterogeneous grain size distribution, misorientation of grains and anisotropy of the superficial energy of adjacent grain boundaries.
Some mixing models that allow to calculate the electrical conductivity of a composite as a function of a melt fraction were examined and the results of these calculations are discussed.
The experimental results were compared to the conductivity data obtained from magnetotelluric and electromagnetic measurements in the Northern part of mid-Atlantic ridge where a series of magma chambers are presumably located. There is a good agreement between our conductivity values for a melt fraction of 10-13 the conductivity estimated in the Reykjanes ridge zone.
Fluctuations of charged particle number are studied in the canonical ensemble. In the infinite volume limit the fluctuations in the canonical ensemble are different from the fluctuations in the grand canonical one. Thus, the well-known equivalence of both ensembles for the average quantities does not extend for the fluctuations. In view of a possible relevance of the results for the analysis of fluctuations in nuclear collisions at high energies, a role of the limited kinematical acceptance is studied.
We present STAR measurements of the azimuthal anisotropy parameter v2 and the binary-collision scaled centrality ratio RCP for kaons and lambdas ( Lambda + Lambda -bar) at midrapidity in Au+Au collisions at sqrt[sNN]=200 GeV. In combination, the v2 and RCP particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish pT ~ 5 GeV/c as the value where the centrality dependent baryon enhancement ends. The K0S and Lambda + Lambda -bar v2 values are consistent with expectations of constituent-quark-number scaling from models of hadron formation by parton coalescence or recombination.
