AbstractInterdisciplinary research often involves analyzing data obtained from different data sources with respect to the same subjects, objects, or experimental units. For example, global positioning systems (GPS) data have been coupled with travel diary data, resulting in a better understanding of traveling behavior. The GPS data and the travel diary data are very different in nature, and, to analyze the two types of data jointly, one often uses data integration techniques, such as the regularized simultaneous component analysis (regularized SCA) method. Regularized SCA is an extension of the (sparse) principle component analysis model to the cases where at least two data blocks are jointly analyzed, which - in order to reveal the joint and unique sources of variation - heavily relies on proper selection of the set of variables (i.e., component loadings) in the components. Regularized SCA requires a proper variable selection method to either identify the optimal values for tuning parameters or stably select variables. By means of two simulation studies with various noise and sparseness levels in simulated data, we compare six variable selection methods, which are cross-validation (CV) with the “one-standard-error” rule, repeated double CV (rdCV), BIC, Bolasso with CV, stability selection, and index of sparseness (IS) - a lesser known (compared to the first five methods) but computationally efficient method. Results show that IS is the best-performing variable selection method.

A set of four econometric models is presented to examine the tour and episode-related attributes (specifically, mode choice, activity duration, travel times, and location choice) of the activity-travel patterns of non-workers, as a sequel to an earlier work by Bhat and Misra (2001), which presented a comprehensive continuous-time framework for representation and analysis of the activity-travel choices of nonworkers. Detailed descriptions of the first two components of the modeling framework related to the number and sequence of activity episodes are also presented. The proposed models using activity-travel data from the 1990 San Francisco Bay Area travel diary survey are estimated.

Piedmont Region

In the Piedmont region (Italy) the electronic ticketing system called BIP, is currently active across much of its territory, and thedata collected in the Province of Cuneo since the full activation of the system (2014) provide today a sound source ofinformation. Two different travel documents are available, travel passes and pay-per-use, with different validation rules: check-inonly for travel passes and check-in and check-out for pay-per-use. Data produced by this electronic ticketing system employingsmart cards allow to perform a detailed analysis of each user’s behaviour, and calculate time and space distributions of eachpassenger trip. In detail, data originating from smart card transactions allow to trace back the trip chains, establish journey originsand destinations, and produce a “travel diary” for each passenger. Based on this data, performance indicators (i.e. load factor) aswell as user mobility patterns and origin-destination matrices can be calculated in an automated and reliable way. This articlepresents a methodology for assessing the quality of the data collected when information about boarding and alighting stops isavailable from the (on board) validation system. It also presents an algorithm to assign a destination for each trip where only theboarding information is available. In the case study of the Province of Cuneo, it was found that 91% of the pay-per-use journeydata are reliable and can be used for further analysis, whereas with the use of the proposed algorithm it was possible to estimatethe destinations for 82% of the travel pass trips.DOI: http://dx.doi.org/10.4995/CIT2016.2016.1999

German Universities

“By the summer of 1934,” Hermione Lee writes, Hitler's “ambitions and his methods were fully apparent.” In the mid-1930s, Nazis issue regulations to eliminate women doctors and lawyers in Germany. German universities reduce the female quota of students to just ten percent. On October 28, 1934, Oswald Mosley stages a vicious attack on Jews during a British Union of Fascists rally at the Royal Albert Hall. Beyond these alarming national and international threats, Woolf faces inner personal (and artistic) loss and outer public attack, as she writes in her diary. She starts to speak of “warnings” in this journal. However, André Gide’s Pages de Journal, 1929–32 give her new direction in August 1934. In September, Guy de Maupassant's travel diary Sur l’eau (Afloat) particularly helps her to navigate through Roger Fry's unexpected death. She both enters its words in her diary and uses Afloat for a key moment in her novel The Years. In October, Alice James's Journal helps Woolf calibrate British women's social and sexual lives in the first decades of The Years and shows her—as do Gide's and Maupassant's diaries—a fierce fight, both without and within, between constraint and freedom.

Artistic Self

Woolf's next two diary books, her 1932 diary and her 1933–34 diary, help her to navigate the difficult strait between the outer and the inner conflicts. She needs these diaries’ support, for, as the gathering outer storm forms, she faces both the strains of her inner artistic self and the loss of her friends. In late November of 1933, she consciously turns from the troubling outer world to the dual-voiced diary of Katherine Bradley and Edith Cooper, the aunt and niece verse dramatists who published together under the name Michael Field. There, she finds not only lesbian playwrights and their trials but also the word “outsiders.” In February 1934, her response to a famous travel diary—Arthur Young’s Travels in France during the years 1787, 1788, 1789—shows her recoil from war.
