Observations on the flight paths of the day-flying moth Virbia lamae during periods of mate location: do males have a strategy for contacting the pheromone plume?

1. To maximize the probability of rapid contact with a female’s pheromone plume, the trajectories of male foraging flights might be expected to be directed with respect to wind flow and also to be energetically efficient. 2. Flights directed either upwind, downwind, or crosswind have been proposed as optimal strategies for rapid and/or energetically efficient plume contact. Other possible strategies are random and Lévy walks, which have trajectories and turn frequencies that are not dictated by the direction of wind flow. 3. The planar flight paths of males of the day-active moth Virbia lamae were recorded during the customary time of its sexual activity. 4. We found no directional preference in these foraging flights with respect to the direction of contemporaneous wind flow, but, because crosswind encompasses twice the possible orientations of either upwind or downwind, a random orientation is in effect a de facto crosswind strategy. 5. A crosswind preference should be favoured when the plume extends farther downwind than crosswind, and this strategy is realized by V. lamae males by a random orientation of their trajectories with respect to current wind direction

A new calibrated sunspot group series since 1749: statistics of active day fractions

Although the sunspot-number series have existed since the mid-19th century, they are still the subject of intense debate, with the largest uncertainty being related to the "calibration" of the visual acuity of individual observers in the past. Daisy-chain regression methods are applied to inter-calibrate the observers which may lead to significant bias and error accumulation. Here we present a novel method to calibrate the visual acuity of the key observers to the reference data set of Royal Greenwich Observatory sunspot groups for the period 1900-1976, using the statistics of the active-day fraction. For each observer we independently evaluate their observational thresholds [S_S] defined such that the observer is assumed to miss all of the groups with an area smaller than S_S and report all the groups larger than S_S. Next, using a Monte-Carlo method we construct, from the reference data set, a correction matrix for each observer. The correction matrices are significantly non-linear and cannot be approximated by a linear regression or proportionality. We emphasize that corrections based on a linear proportionality between annually averaged data lead to serious biases and distortions of the data. The correction matrices are applied to the original sunspot group records for each day, and finally the composite corrected series is produced for the period since 1748. The corrected series displays secular minima around 1800 (Dalton minimum) and 1900 (Gleissberg minimum), as well as the Modern grand maximum of activity in the second half of the 20th century. The uniqueness of the grand maximum is confirmed for the last 250 years. It is shown that the adoption of a linear relationship between the data of Wolf and Wolfer results in grossly inflated group numbers in the 18th and 19th centuries in some reconstructions.

Sine ira et studio : En kvalitativ analys av institutionaliseringsprocessens konsekvenser inom den nypaganistiska rörelsen Church of All Worlds

Uppsatsen har för avsikt att undersöka hur den nypaganistiska, och i första hand nordamerikanska, rörelsen Church of All Worlds reagerar mot förändring och institutionalisering. För att förstå institutionaliseringsprocessens bakomliggande krafter och identifiera dess konsekvenser, är det övergripande syftet med uppsatsen att utifrån en fallstudie av Church of All Worlds undersöka hur organisationen under sina verksamhetsår förändrats i fråga om (1) förhållande till samhället, (2) ideologi, (3) organisatorisk struktur och (4) ledarskap. Utgångspunkten är att betrakta rörelsen som dels religiös och spirituell, dels organisatorisk och ekonomisk, varför uppsatsen lutar sin teoribildning mot både religions- och samhällsvetenskapen och mot organisationsteorin. Som samhälleliga samt organisatoriska faktorer till Church of All Worlds institutionalisering finner vi den postmoderna motreaktionen mot industrisamhällets missförhållanden samt kritiken mot existensen av den objektiva sanningen. Institutionaliseringens följder är emellertid att rörelsen slutligen upptas som en del av det sen-moderna samhällssystemet. Förändringen märks i första hand då rörelsen under 80-talet förvandlas till en ekonomiskt intresserad organisation med tjänstehierarkier och reglerat ansvar som påföljder. Den byråkratiska arbetsordningen urlakar inte bara rörelsens ideologi, utan tvingar också den nu demokratiskt tillsatte ledaren till radikala åtgärder för att återfå sin makt, något som når sin kulmen i en konflikt med ledarens sorti som yttersta konsekvens.

Production performance and egg quality of quails (Coturnix japonica) during several periods of the day

Three experiments were carried out to analyze the performance and egg quality of Japanese quails throughout the day when submitted to different lighting programs. In each experiment, birds were submitted to a period of 28 days for adaptation to the lighting program. During the following three days, each day - from 7 am to 7 pm or 9 pm - was divided into six or seven periods of two hours each, and the remaining hours corresponded to another single period. All birds were submitted to the same management practices, and received water and feed ad libitum. The experimental diet was formulated according to NRC (1994) standards. It was observed lower feed intake in the period of 9 pm to 7 am, and a higher incidence of lay from 3 pm to 7 pm, as opposite to hens, which peak of egg laying occurs during the morning. Some controversial results were found among experiments as to eggshell quality during the different periods of the day. Variation on the lighting program had little influence on the other performance and egg quality parameters.

A Case Study: The Effect of Visitors on Two Captive Pumas With Respect to the Time of the Day

This study analyzed the effects of noise levels and number of visitors on the behaviors of a mother puma and her daughter in a zoo environment with respect to the time of day. The study monitored visitation (noise and number) over two 1-week periods (4 weeks between periods) and frequency of various puma behaviors (videorecorded). The study analyzed videotaped behavior of the pumas based on the time of day and visitors number and noise levels. There was a direct association of puma behaviors with visitors number and noise levels. The daughter puma was the most affected and behavioral changes of both pumas correlated more strongly with the noise level than the number of visitors. The noise level and number of visitors affected the behavior of the mother and her daughter only in the morning. The results of this study indicate that both noise level and number of visitors affected these pumas but revealed the noise as predominant. Moreover, the response of these pumas to visitors depended on the time of the day.

Blastocystis hominis: occurrence in children and staff members of municipal day-care centers from Botucatu, São Paulo State, Brazil

To study the frequency of Blastocystis hominis among healthy individuals, feces were collected from 153 children and 20 staff members of some municipal day-care centers. Three separate stool specimens of each individual were processed by Lutz and Faust methods. From 173 studied individuals, 60 (34.7%) showed B. hominis, frequently in association with other intestinal parasites and/or commensals. B. hominis was found mainly in adults and children between 36 and 72 months old. All positive cases were detected only by Lutz method and the use of three stool specimens increased the positivity of the parasitological diagnostic.

Leucometric analysis of 1-day-old chicks inoculated with Salmonella Typhimurium or Lactobacilli

Salmonella infection is responsible for major economic losses in poultry industry. Consequently, the development of new methods for fighting such disease is desirable, such as the use of acid-lactic bacteria. However, reference values of chicks in such conditions are dissimilar to those of other species. Leucometry reference values for chicks have not been reported. The aim of this article was to evaluate and determine the leucometric values of chicks inoculated with Salmonella Typhimurium or treated with Lactobacilli probiotics. In this study, 144 1-day-old birds were divided in three groups of 48 animals each (non-treated group, Salmonella Typhimurium (ST)-inoculated group, and Lactobacilli inoculated group). A total of four blood collections were made with the first one performed 3 h after inoculation with ST or treatment with Lactobacilli. Subsequent samples were obtained every 48 h for 7 days. Leucometric evaluation was performed immediately after each collection. All birds presented an initial decrease pattern in general leukocyte values, and the chicks inoculated with ST revealed lymphomonoheteropaenic leukopaenia, eosinophilia and basophilia in conjunction with convalescence after 96 h of inoculation. The animals inoculated with Lactobacilli revealed leucocytosis with monocytosis, lymphocytosis and marked eosinopaenia. We conclude that there is no efficient bone marrow response in 1-day-old chicks challenged with Salmonella Typhimurium; additionally, an immunostimulatory effect in 1-day-old chicks treated with Lactobacilli-modulated probiotics could be stated. © 2011 Springer-Verlag London Limited.

Rebranding feminism: An analysis of present-day feminism

The purpose of this dissertation is to reflect on the meaning of feminism in order to decide whether the movement needs a rebranding. The first part will focus on the history of feminism to clarify its beliefs and goals. The following part will highlight how feminism gained a bad reputation over time and will show Elle’s attempt in November 2013 to launch a project to rebrand the movement. The last part will explain what present-day feminism consists of by listing some of the latest projects and the most important issues the movement has to tackle. My analysis will finally show that the F-movement needs a rebranding and, in order to be effective, men should join women’s fight for equality. “We should all be feminists”.
