Content-Based Video Retrieval in Historical Collections of the German Broadcasting Archive
The German Broadcasting Archive (DRA) maintains the cultural heritage of
radio and television broadcasts of the former German Democratic Republic (GDR).
The uniqueness and importance of the video material stimulates a large
scientific interest in the video content. In this paper, we present an
automatic video analysis and retrieval system for searching in historical
collections of GDR television recordings. It consists of video analysis
algorithms for shot boundary detection, concept classification, person
recognition, text recognition and similarity search. The performance of the
system is evaluated from a technical and an archival perspective on 2,500 hours
of GDR television recordings.Comment: TPDL 2016, Hannover, Germany. Final version is available at Springer

It's OK not to be OK: Shared Reflections from two PhD Parents in a Time of Pandemic
Adopting an intersectional feminist lens, we explore our identities as single and coâparents thrust into the new reality of the UK COVIDâ19 lockdown. As two PhD students, we present shared reflections on our intersectional and divergent experiences of parenting and our attempts to protect our work and families during a pandemic. We reflect on the social constructions of âmasculinitiesâ and âemphasized femininitiesâ as complicated influence on our roles as parents. Finally, we highlight the importance of time and selfâcare as ways of managing our shared realities during this uncertain period. Through sharing reflections, we became closer friends in mutual appreciation and solidarity as we learned about each otherâs struggles and vulnerabilities
The challenge of parenting girls in neighborhoods of different perceived quality
It is well-known that disadvantaged neighborhoods, as officially identified through census data, harbor higher numbers of delinquent individuals than advantaged neighborhoods. What is much less known is whether parentsâ perception of the neighborhood problems predicts low parental engagement with their girls and, ultimately, how this is related to girlsâ delinquency, including violence. This paper elucidates these issues by examining data from the Pittsburgh Girls Study, including parent-report of neighborhood problems and level of parental engagement and official records and girl-reported delinquency at ages 15, 16, and 17. Results showed higher stability over time for neighborhood problems and parental engagement than girlsâ delinquency. Parentsâ perception of their neighborhood affected the extent to which parents engaged in their girlsâ lives, but low parental engagement did not predict girls being charged for offending at age 15, 16 or 17. These results were largely replicated for girlsâ self-reported delinquency with the exception that low parental engagement at age 16 was predictive of the frequency of girlsâ self-reported delinquency at age 17 as well. The results, because of their implications for screening and early interventions, are relevant to policy makers as well as practitioners

School-related stress among sixth-grade students - associations with academic buoyancy and temperament
The present study examined to what extent sixth-grade studentsâ academic buoyancy and temperament contributed to their school-related stress. A total of 845 students rated their school-related stress at the beginning and end of the school year and their academic buoyancy at the beginning of the year. Parents rated studentsâ effortful control and negative affectivity. The results showed that high academic buoyancy, high effortful control, and low negative affectivity at the beginning of the school year were related to lower school-related stress at the end of the school year, after controlling for gender, GPA, and previous level of stress. Effortful control and negative affectivity had no significant interaction effect with academic buoyancy on studentsâ school-related stress. The findings of the study suggest that interventions aiming at supporting studentsâ academic buoyancy may also decrease their feelings of school stress. In particular, students with high negative affectivity or low effortful control may need training in stress management skills

Strong Coupling Corrections to the Ginzburg-Landau Theory of Superfluid ^{3}He
In the Ginzburg-Landau theory of superfluid He, the free energy is
expressed as an expansion of invariants of a complex order parameter. Strong
coupling effects, which increase with increasing pressure, are embodied in the
set of coefficients of these order parameter invariants\cite{Leg75,Thu87}.
Experiments can be used to determine four independent combinations of the
coefficients of the five fourth order invariants. This leaves the
phenomenological description of the thermodynamics near incomplete.
Theoretical understanding of these coefficients is also quite limited. We
analyze our measurements of the magnetic susceptibility and the NMR frequency
shift in the -phase which refine the four experimental inputs to the
phenomenological theory. We propose a model based on existing experiments,
combined with calculations by Sauls and Serene\cite{Sau81} of the pressure
dependence of these coefficients, in order to determine all five fourth order
terms. This model leads us to a better understanding of the thermodynamics of
superfluid He in its various states. We discuss the surface tension of
bulk superfluid He and predictions for novel states of the superfluid
such as those that are stabilized by elastic scattering of quasiparticles from
a highly porous silica aerogel.Comment: 9 pages, 7 figures, 2 table
Physioacoustic therapy: placebo effect on recovery from exercise-induced muscle damage
We evaluated claims that physioacoustic therapy can enhance muscle healing following damaging exercise. Untrained subjects were randomly assigned to control (C), placebo (P) or treatment (T) groups. All groups performed 70 eccentric triceps contractions followed by; no treatment (C), sham physioacoustic treatment (P), or actual physioacoustic therapy (T) on days 1â4 post-exercise. Muscle soreness and isometric and concentric triceps peak torque were determined pre-exerciseand on days 1â4 and 7 post-exercise. The T group received physioacoustic therapy for 30 min/day on the treatment days. The P group believed they received physioacoustic therapy, although the chairs were turned off. Peak torques were depressed (P < 0.05) on days 1â3 in all groups and returned to pre-exercise values by days 4â7 in both P and T groups. C group peak torques remained depressed (P < 0.05) through day 7. Soreness was elevated (P < 0.05) in all groups on days 1â2 post-exercise. P and T groups reported no soreness by day 3 while the C group remained sore (P < 0.05) through days 3â4. The T group recovered soreness and force faster than C but at a similar rate to the P group. The effectiveness of physioacoustic therapy in enhancing post-exercise muscle healing may be attributable to a placebo effect
