Preservation Planning for Digital Audio-Visual Material at the German National Library of Science and Technology (TIB) – Developing a Catalogue of Criteria and a Migration Plugin

The German Nation Library of Science and Technology (TIB) runs a digital archive in order to preserve its digital holdings which consists amongst others of audio-visual material. In order to identify obsolete audio-visual file formats a catalogue of criteria is developed and file formats which represent the majority of TIB’s audio-visual holdings are examined. The assessment reveals that the examined file formats are not a preferred file format for digital preservation, but on the other hand they are not at risk to become obsolete to TIB’s designated community. Furthermore, a migration plugin for the digital archive’s software environment is developed and successfully deployed. The migration plugin can be used during preservation planning in order to migrate the examined formats into TIB’s chosen archival file format if a migration becomes necessary

Challenge, learning, innovation and cooperation in understanding your landscape : handbook for teachers

BookThe landscape consists of both the external environment, where each of us lives, and how we perceive it – as familiar, comforting, dangerous, ugly, beautiful etc. We see it from our window, we walk and drive through it and we visit it for recreation or on holiday. It plays an important but often under-appreciated role in our quality of life, or sense of belonging and as a background for many activities. At a European level the landscape is recognised and given prominence through the European Landscape Convention (ELC). The ELC is important for raising awareness of the landscape and enshrined in the convention text is the need for citizens to become involved in looking after it. However, this need is not very widely known nor is it clear how citizens are supposed to become active in their local landscape. The E-CLIC project, carried out under the auspices of the EU Lifelong Learning Programme aimed to start the process of rectifying this omission by developing new and exciting ways for everyone to learn, innovate and cooperate. The concept of lifelong learning is that learning is not something we do only at school or university and then stop but that we need to learn all through our lives. Since the world around us – including the landscape – is constantly changing we need to be adaptable and for this we need to keep learning. Landscape is not a static backdrop to our activities but it changes around us and our own actions change it too, directly and indirectly. In different places there are different pressures on the landscape – urban development, rural change, effects on heritage and identity and the impacts of infrastructure and tourism – important and specific challenges. If we care about our surroundings enough to want to help to protect the landscape or to participate in planning for its development then we need tools to help us respond and understand the challenges and to enable us to participate more meaningfully. This handbook for teachers at secondary school, university and continuing education levels provides guidance on how to use the large number of resources and tools developed within the E-CLIC project and ways of incorporating landscape and the ELC into existing educational curricula and programmes. The resources and tools developed within the E-CLIC project include: • A Learning package aiming to familiarise the learner with the ELC, the challenges facing the landscape in different countries and ways to communicate solutions to such challenges by using IT methods and tools. • A review report of landscape-related policy issues. • A Best Practice Library of case studies relating to the implementation of ELC measures. • A Library of ICT resources • The results of a European-wide competition which produced interesting and imaginative solutions to landscape challenges. Essentially, the handbook can be used as part of environmental education or promoting public awareness of European landscape policy and most important attract the active participation of people in the assessment of their local landscape. The ELC is to be taken as a basis for raising the interest of youth and young/older adults in a number of everyday and universal “values” that it helps to promote the landscape!This project has been funded with the support of the European Commission

Sleep problems in university students - an intervention

Schlarb A, Friedrich A, Claßen M. Sleep problems in university students - an intervention. Neuropsychiatric Disease and Treatment. 2017;2017(13):1989-2001.Introduction: Up to 60% of all college students suffer from a poor sleep quality, and 7.7% meet all criteria of an insomnia disorder. Sleep problems have a great impact on the students’ daily life, for example, the grade point average. Due to irregular daytime routines, chronotype changes, side jobs and exam periods, they need specialized treatments for improving sleep. “Studieren wie im Schlaf” (SWIS; (studying in your sleep)) is a multicomponent sleep training that combines Cognitive Behavioral Therapy for Insomnia and Hypnotherapy for Insomnia to improve students’ sleep, insomnia symptoms and nightmares. The aim of the present study is to evaluate the acceptance, feasibility and the first effects of SWIS. Methods: Twenty-seven students (mean =24.24, standard deviation =3.57) participated in a study of pre–post design. The acceptance and feasibility were measured with questionnaires. In addition, the Pittsburgh Sleep Quality Index (PSQI), sleep logs and actigraphy were implemented. Further variables encompassed daytime sleepiness, sleep-related personality traits and cognitions about sleep. Results: Seventy-four percent of the participants reported symptoms of an insomnia disorder, and 51.9% fulfilled all criteria of an insomnia disorder according to the Diagnostic and Statistical Manual of Mental Disorders (fifth edition). Correspondingly, the students suffered from clinically relevant sleep problems according to the PSQI. The SWIS sleep training is a well-accepted and feasible program. Significant improvements were observed in the subjective sleep quality and sleep-related personality traits, as well as clinical improvements in objective sleep measures. Discussion: Findings showed that SWIS is a feasible program for the treatment of sleep problems in college and university students due to its various effects on sleep and cognitive outcomes. Further evaluation of follow-up measurements and additional variables, that is, cognitive performance and mental health, is needed

Sleep better, feel better? Effects of a CBT-I and HT-I sleep training on mental health, quality of life and stress coping in university students: a randomized pilot controlled trial

Friedrich A, Claßen M, Schlarb A. Sleep better, feel better? Effects of a CBT-I and HT-I sleep training on mental health, quality of life and stress coping in university students: a randomized pilot controlled trial. BMC Psychiatry. 2018;18(1): 268.Background The SWIS sleep training for university students showed promising results regarding subjective and objective sleep parameters. As sleep disorders and impaired sleep quality are closely related to various aspects of mental health, the current study examines the effects of the SWIS sleep training on mental health in university students. Methods Fifty six university students (M = 25.84, SD = 5.06) participated in the study, 68% were women. Forty one were randomly assigned to the SWIS treatment (pre-post-follow-up), 15 to a Waiting List Control condition (WLC, pre-post). Besides sleep-related measures, the students completed four online questionnaires measuring mental health, quality of life and stress coping strategies. Effect sizes for the pre-post data were compared between the conditions, long-term effects were calculated with repeated measures ANOVA or Friedman ANOVA. Long-term clinical changes were analyzed with the Reliable Change Index (RCI). Results The pre-post comparisons between SWIS and WLC revealed lower depression scores in both conditions, a better physical state in the SWIS condition and less maladaptive stress coping strategies in the WLC students. The long-term results of SWIS provided significant improvements regarding the students’ somatic complaints, reduced anxiety, an improved physical state and a better quality of life with moderate to large effect sizes. Most of the significant improvements occurred between pre- and follow-up measurement. These statistically significant results were also reflected in clinically significant changes from pre- to follow-up-test. Conclusions SWIS and WLC condition both improved in two mental health variables immediately after the training. These findings may be explained by unspecific treatment expectation effects in the WLC. Interestingly, most mental health outcomes showed significant improvements after 3 months, but not immediately after the training. These positive long-term effects of the SWIS training on mental health indicate that the transfer of strategies might simply need more time to affect the students’ mental health

The Neutron Charge Form Factor and Target Analyzing Powers From \u3csup\u3e3\u3c/sup\u3eHe (e→, e \u27n) Scattering

The charge form factor of the neutron has been determined from asymmetries measured in quasi-elastic 3He(e→, e \u27n) at a momentum transfer of 0.67 (GeV/c)2. In addition, the target analyzing power, Ayo has been measured to study effects of final state interactions and mespn exchange currents

Separated cross sections in \pi^0 electroproduction at threshold at Q^2 = 0.05 GeV^2/c^2

The differential cross sections \sigma_0=\sigma_T+\epsilon \sigma_L, \sigma_{LT}, and \sigma_{TT} of \pi^0 electroproduction from the proton were measured from threshold up to an additional center of mass energy of 40 MeV, at a value of the photon four-momentum transfer of Q^2= 0.05 GeV^2/c^2 and a center of mass angle of \theta=90^\circ. By an additional out-of-plane measurement with polarized electrons \sigma_{LT'} was determined. This showed for the first time the cusp effect above the \pi^+ threshold in the imaginary part of the s-wave. The predictions of Heavy Baryon Chiral Perturbation Theory are in disagreement with these data. On the other hand, the data are somewhat better predicted by the MAID phenomenological model and are in good agreement with the dynamical model DMT.Comment: 6 pages, 4 figure

Coherent \pi^0 threshold production from the deuteron at Q^2 = 0.1 GeV^2/c^2

First data on coherent threshold \pi^0 electroproduction from the deuteron taken by the A1 Collaboration at the Mainz Microtron MAMI are presented. At a four-momentum transfer of q^2=-0.1 GeV^2/c^2 the full solid angle was covered up to a center-of-mass energy of 4 MeV above threshold. By means of a Rosenbluth separation the longitudinal threshold s wave multipole and an upper limit for the transverse threshold s wave multipole could be extracted and compared to predictions of Heavy Baryon Chiral Perturbation Theory.Comment: 7 pages, 7 figures, latex2

Final State Interaction Effects in pol 3He(pol e,e'p)

Asymmetries in quasi-elastic pol 3He(pol e,e'p) have been measured at a momentum transfer of 0.67 (GeV/c)^2 and are compared to a calculation which takes into account relativistic kinematics in the final state and a relativistic one-body current operator. With an exact solution of the Faddeev equation for the 3He-ground state and an approximate treatment of final state interactions in the continuum good agreement is found with the experimental data.Comment: 11 pages, 6 figures, submitted to Phys.

A measurement of the axial form factor of the nucleon by the p(e,e'pi+)n reaction at W=1125 MeV

The reaction p(e,e'pi+)n was measured at the Mainz Microtron MAMI at an invariant mass of W=1125 MeV and four-momentum transfers of Q^2=0.117, 0.195 and 0.273 (GeV/c)^2. For each value of Q^2, a Rosenbluth separation of the transverse and longitudinal cross sections was performed. An effective Lagrangian model was used to extract the `axial mass' from experimental data. We find a value of M_A=(1.077+-0.039) GeV which is (0.051+-0.044) GeV larger than the axial mass known from neutrino scattering experiments. This is consistent with recent calculations in chiral perturbation theory.Comment: 14 pages, 5 figures, uses elsart.cl

Measurement of the LT-asymmetry in \pi^0 electroproduction at the energy of the \Delta (1232) resonance

The reaction p(e,e'p)pi^0 has been studied at Q^2=0.2 (GeV/c)^2 in the region of W=1232 MeV. From measurements left and right of q, cross section asymmetries \rho_LT have been obtained in forward kinematics \rho_LT(\theta_\pi^0=20deg) = (-11.68 +/- 2.36_stat +/- 2.36_sys)$ and backward kinematics \rho_LT(\theta_\pi^0=160deg) =(12.18 +/- 0.27_stat +/- 0.82_sys). Multipole ratios \Re(S_1+^* M_1+)/|M_1+|^2 and \Re(S_0+^* M_1+)/|M_1+|^2 were determined in the framework of the MAID2003 model. The results are in agreement with older data. The unusally strong negative \Re(S_0+^* M_1+)/|M_1+|^2 required to bring also the result of Kalleicher et al. in accordance with the rest of the data is almost excluded.Comment: 7 pages, 7 figures, 4 tables.
