FastTTPS: fast approach for video transcoding time prediction and scheduling for HTTP adaptive streaming videos
Authors: Agrawal Prateek , Zabrovskiy Anatoliy , Ilangovan Adithyan , Timmerer Christian , Prodan Radu 
Published: November 2020

AbstractHTTP adaptive streaming of video content becomes an integrated part of the Internet and dominates other streaming protocols and solutions. The duration of creating video content for adaptive streaming ranges from seconds or up to several hours or days, due to the plethora of video transcoding parameters and video source types. Although, the computing resources of different transcoding platforms and services constantly increase, accurate and fast transcoding time prediction and scheduling is still crucial. We propose in this paper a novel method called fast video transcoding time prediction and scheduling (FastTTPS) of x264 encoded videos based on three phases: (i) transcoding data engineering, (ii) transcoding time prediction, and (iii) transcoding scheduling. The first phase is responsible for video sequence selection, segmentation and feature data collection required for predicting the transcoding time. The second phase develops an artificial neural network (ANN) model for segment transcoding time prediction based on transcoding parameters and derived video complexity features. The third phase compares a number of parallel schedulers to map the predicted transcoding segments on the underlying high-performance computing resources. Experimental results show that our predictive ANN model minimizes the transcoding mean absolute error (MAE) and mean square error (MSE) by up to 1.7 and 26.8, respectively. In terms of scheduling, our method reduces the transcoding time by up to 38% using a Max–Min algorithm compared to the actual transcoding time without prediction information.
Grounding the case for a European approach to the regulation of automated driving: the technology-selection effect of liability rules
Authors: Bertolini Andrea , Riccaboni Massimo 
Published: November 2020

AbstractIn the current paper, we discuss the need for regulation at EU level of Connected and Automated Driving solutions (henceforth CAD) based on multiple considerations, namely (i) the need for uniformity of criteria across European Member States, and (ii) the impact that regulation—or the absence of it—has on the proliferation of specific technological solutions. The analysis is grounded on legal and economic considerations of possible interactions between vehicles with different levels of automation, and shows how the existing framework delays innovation. A Risk-Management Approach, identifying one sole responsible party ex ante (one-stop-shop), liable under all circumstances—pursuant to a strict, if not absolute liability rule—is to be preferred. We analyse the solution adopted by some Member States in light of those considerations and conclude that none truly corresponds to a RMA approach, and differences will also cause market fragmentation. We conclude that because legal rules determine what kind of technological application is favoured over others—and thence they are not technology-neutral—uniformity across MSs is of essential relevance, and discuss possible policy approaches to be adopted at European level.
MDOF extension of the Modified Bridge System method for vehicle–bridge interaction
Authors: Stoura Charikleia D. , Dimitrakopoulos Elias G. 
Published: November 2020

AbstractThis study examines the effect of vehicle–bridge interaction (VBI) on the vibration of coupled train–bridge systems and proposes a consistent approach to decouple the VBI problem; the Extended Modified Bridge System (EMBS) method. This constitutes an extension of the formerly developed, for simply supported bridges, Modified Bridge System method. The analysis considers a generic, multi-degree of freedom (MDOF) vehicle–MDOF bridge configuration, representative of a wide class of practical train–bridge systems. This approach enables the MDOF representation of the constituent VBI mechanisms on the mechanical system of the bridge. Based on an asymptotic expansion analysis of the coupled system response, the study brings forward the dominant coupling parameters and their relative importance on the bridge response. The proposed decoupling EMBS method solves the bridge independently of the vehicle by changing its mechanical system via additional damping, stiffness and loading terms. The MDOF description of these terms makes the proposed scheme appropriate for involved bridge configurations, such as continuous and arch bridges. In addition, it allows the accurate estimation of the deck acceleration of bridges, which is an important serviceability limit state. Numerical examples demonstrate the accuracy and efficiency of the EMBS method compared with the solution of the fully coupled system and other decoupling methodologies. Lastly, the proposed approach is simpler than the coupled analysis, which can be of particular importance in bridge design practice.
So Far, so Similar? Labour Market Feminization in Italy and Chile
Authors: Semenza Renata , Boccardo Giorgio , Sarti Simone 
Published: November 2020

AbstractThe article aims to analyse gender segregation in the labour market while comparing two national contexts in Europe and Latin America. Specifically, it will consider the growth trends of female employment in the last 25 years (1992–2017), its distribution between activity sectors and occupations, and the gender pay gap. Feminization models and gender inequalities are framed within labour market segmentation theories, which are in partial contrast to human capital theories and neoclassical economics. The initial hypothesis is that the gender distribution of occupations measured by a segregation index is similar in Italy and Chile, despite significant differences in the socio-economic and institutional contexts. Through this intercontinental comparison, the article intends to shed light on women’s labour market conditions and segregation patterns, which are multidimensional and generalizable (transcontinental) phenomena, connected to the unequal division of labour in the new post-industrial order.
Eldercare in Japan: Cluster Analysis of Daily Time-Use Patterns of Elder Caregivers
Authors: Kolpashnikova Kamila , Kan Man-Yee 
Published: November 2020

AbstractUsing the data of the 2006 Japanese Survey on Time Use and Leisure Activities, we perform cluster analysis and identify seven unique patterns of daily time-use patterns of co-resident family elder caregivers: (1) ‘Overworkers’, (2) ‘Full-time Workers’, (3) ‘Part-time Workers’, (4) ‘Intensive Caregivers’, (5) ‘Houseworkers’, (6) ‘Leisurely’, and (7) caregivers, who needed medical attention on the diary day (‘Emergency Diaries’). Our results show that the ‘Houseworkers’ and ‘Intensive Caregivers’ spend the most time on adult caregiving activities. Care activities for ‘Houseworkers’ are more likely to coincide with longer housework hours, increasing the total unpaid work volume. The analysis of demographic profiles suggests that similar daily patterns on weekdays and weekends do not belong to people with the same demographic characteristics. For instance, although on weekdays, ‘Leisurely Caregivers’ are mostly represented by the elderly taking care of other elderly, people of any age can belong to this category on weekends. Among all types of caregivers, only 'Intensive Caregivers' are as likely to be men as they can be women, suggesting that when the need for eldercare increases, family caregivers of any gender will step in.
Adolescents´ Perceptions, Neighbourhood Characteristics and Parental Monitoring -Are they Related, and Do they Interact in the Explanation of Adolescent Offending?

Published: November 2020

AbstractChildren are nested in families, and families are nested within communities (e.g. neighbourhoods). This implies that the behaviour of both children and their parents is influenced by external and contextual factors. The aim of the present study was to explore the relationship between parental monitoring and neighbourhood disorder and collective efficacy from the perspective of the adolescent and to investigate how perceived monitoring and neighbourhood characteristics were related to and interact in predicting adolescent offending. The characteristics of the adolescent’s neighbourhoods were assessed using two different data sources: adolescents’ own perceptions and an independent, aggregated measure from a community survey. The analyses showed that the adolescents’ perceptions of neighbourhood level of disorder and collective efficacy were associated with both adolescent-perceived parental monitoring and adolescent offending, while the corresponding measures from the community survey were not. As regards the prediction of offending, adolescent-perceived parental monitoring is the most important predictor. Neither collective efficacy nor disorder appear to interact with parental monitoring in explaining adolescent offending. Future research would contribute to the field by examining the effect and interaction between the study variables in a sample with younger adolescents as well as by including parents’ perceptions. As to practical implications, our results indicate that families living in disadvantaged neighbourhoods may benefit from targeted support aimed at handling negative neighbourhood influences.

Published: November 2020

AbstractPsychological variables of a person (e.g., cognitive abilities, personality traits, emotional states, and preferences) are valuable information that can be utilized by social robots to offer personalized human–robot interaction. These variables are often latent and inferred indirectly from a third-person perspective based on an individual’s behavioral manifestations (e.g., facial emotion expressions), and hence the true values of inferred psychological variables remain unknown to a robot observer. Although earlier studies have employed robot-administered psychological tests to infer psychological variables based on an individual’s first-person responses, these tests were formally presented and could be tedious to some users. To leverage the validity and reliability of well-established psychological tests for user profiling with ease, the present study examined the possibility of asynchronously embedding psychological test questions into casual human–robot conversations. In our experiment using a big-five personality inventory, the verbal responses from users to these asynchronous test questions were then compared with the written responses to the same personality test. The personality measures estimated from the two approaches correlated strongly in a young adult population but only moderately in an older population. These findings demonstrate the validity of the proposed asynchronous method for psychological testing in human–agent interactions and suggest some caveats when this testing method is applied to older adults or other special populations.
A Reverse Dynamical Investigation of the Catastrophic Wood-Snow Avalanche of 18 January 2017 at Rigopiano, Gran Sasso National Park, Italy

Published: November 2020

AbstractOn 18 January 2017 a catastrophic avalanche destroyed the Rigopiano Gran Sasso Resort & Wellness (Rigopiano Hotel) in the Gran Sasso National Park in Italy, with 40 people trapped and a death toll of 29. This article describes the location of the disaster and the general meteorological scenario, with field investigations to provide insight on the avalanche dynamics and its interaction with the hotel buildings. The data gathered in situ suggest that the avalanche was a fluidized dry snow avalanche, which entrained a sligthtly warmer snow cover along the path and reached extremely long runout distances with braking effect from mountain forests. The avalanche that reached the Rigopiano area was a “wood-snow” avalanche—a mixture of snow and uprooted and crushed trees, rocks, and other debris. There were no direct eyewitnesses at the event, and a quick post-event survey used a numerical model to analyze the dynamics of the event to estimate the pressure, velocity, and direction of the natural flow and the causes for the destruction of the hotel. Considering the magnitude and the damage caused by the event, the avalanche was at a high to very high intensity scale.
CBT at the Crossroads: The Rise of Transdiagnostic Treatments
Authors: Schaeuffele Carmen , Schulz Ava , Knaevelsrud Christine , Renneberg Babette , Boettcher Johanna 
Published: November 2020

AbstractTransdiagnostic treatments span a heterogeneous group of interventions that target a wider range of disorders and can be applied to treat several disorders simultaneously. Several meta-analyses have highlighted the evidence base of these novel therapies. However, these meta-analyses adopt different definitions of transdiagnostic treatments, and the growing field of transdiagnostic therapies has become increasingly difficult to grasp. The current narrative review proposes a distinction of “one size fits all” unified and “my size fits me” individualized approaches within transdiagnostic therapies. Unified treatments are applied as “broadband” interventions to a range of disorders without tailoring to the individual, while individualized treatments are tailored to the specific problem presentation of the individual, e.g., by selecting modules within modular treatments. The underlying theoretical foundation and relevant empirical evidence for these different transdiagnostic approaches are examined. Advantages and limitations of the transdiagnostic treatments as well as future developments are discussed.
Same Same But Different? Analysen zur Struktur kollegialer Kooperation unter Lehrkräften im Kontext von Schul- und Unterrichtsentwicklung
Authors: Hartmann Ulrike , Richter Dirk , Gräsel Cornelia 
Published: November 2020

ZusammenfassungIn dieser Studie wird ein Fragebogeninstrument zur Erfassung kollegialer Kooperation bei Lehrkräften vorgestellt. Auf der Basis konzeptueller Annahmen zur Kooperation in Kollegien werden zwei Kooperationsformen (Austausch/low cost und Kokonstruktion/high cost) sowie zwei Inhaltsbereiche (Schul- und Unterrichtsentwicklung) erfasst. An einer Stichprobe von 773 Lehrkräften aus 16 weiterführenden Schulen mehrerer deutscher Bundesländer wird die Struktur des Instrumentes mittels konfirmatorischer Faktorenanalysen untersucht. Dabei zeigt sich, dass das Modell, in dem Formen und Inhalte kollegialer Kooperation gleichzeitig berücksichtigt werden, die beste Passung zu den erhobenen Daten aufweist. Die kollegiale Zusammenarbeit zwischen Lehrkräften lässt sich angesichts der vorliegenden Ergebnisse als mehrdimensionales Konstrukt beschreiben. Deskriptive Analysen legen in Übereinstimmung mit bisheriger Forschung nahe, dass Aktivitäten zur unterrichtsbezogenen Kokonstruktion eher selten in Kollegien stattfinden, während ein unterrichtsbezogener Austausch häufiger stattfindet. Im Bereich der schulentwicklungsbezogenen Kooperation fallen die Unterschiede zwischen den Kooperationsformen geringer aus. Die Ergebnisse stützen die faktorielle Validität für eine Erfassung kollegialer Kooperation situiert in spezifischen Inhaltsbereichen der Schul- und Unterrichtsentwicklung.
Situative Beobachtung und Wahrnehmung angehender frühpädagogischer Fachpersonen im Bereich Mathematik – Entwicklung und Validierung eines Testinstruments
Authors: Bruns Julia , Strahl Carolin , Gasteiger Hedwig 
Published: November 2020

ZusammenfassungFrühe mathematische Bildung findet in der Kindertagesstätte insbesondere in spontanen Alltagssituationen statt. Damit diese Alltagssituationen zu natürlichen Lernsituationen für die Kinder werden, müssen (angehende) frühpädagogische Fachkräfte zunächst das mathematische Potenzial in diesen Situationen erkennen. Diese Fähigkeit zur situativen Beobachtung und Wahrnehmung ist bisher unzureichend erforscht, was unter anderem auf begrenzte Methoden zur standardisierten Erfassung dieses Konstrukts zurückzuführen ist. Um diesem Bedarf zu begegnen, wurde das videobasierte Testinstrument Vimas_num zur Erfassung der Fähigkeit zur situativen Beobachtung und Wahrnehmung angehender frühpädagogischer Fachpersonen im Bereich Mengen und Zahlen entwickelt. Auf der Grundlage von drei aufeinander aufbauenden Studien wird die Validität verschiedener Aspekte der Testwertinterpretation untersucht. Die Ergebnisse geben Hinweise auf die Validität der Testwertinterpretation in Bezug auf den Testinhalt, die interne Struktur des Tests und die Zusammenhänge mit theoretisch verbundenen Konstrukten.

ABSTRACT

Introduction:
Diabetic foot ulcers (DFU) is a major social issue in terms of treatment cost. DFU has a high risk of infection with morbidity and an increased risk of lower-extremity amputations. Currently, there are no satisfactory treatments for DFU. This motivates a search for methods that can stimulate the acceleration of wound healing; one of these methods is the use of hyperbaric oxygen therapy (HBOT). This study attempts to prove the ability of HBOT to accelerate the healing process of DFU by increasing levels of both serum Interleukin 6 (IL-6) and Vascular Endothelial Growth Factor (VEFG), assessed by the perfusion, extent, depth, infection and sensation (PEDIS) score.

Methods:
Twenty DFU patients were divided into two groups. The control group underwent a holistic DFU treatment without HBOT and was tested twice for serum IL-6 and VEGF levels, 1 day apart. The HBOT group underwent a holistic DFU treatment with HBOT and was also tested twice for serum IL-6 and VEGF levels: one day before HBOT and 2 h after the first day of HBOT.

Results:
The changes in serum IL-6 and VEGF levels were greater in patients with HBOT than in control patients (p = 0.025 and p = 0.004). As for PEDIS score assessment, the HBOT group had significantly lower PEDIS scores than the control group (p < 0.001).

Conclusion:
HBOT can help accelerate the wound healing process, which was proven by increased serum IL-6 and VEGF levels and a lower PEDIS score.

ABSTRACTResearch on flight emissions at airports is very important for environmental policymaking. This study analysed the trend of aircraft air pollutant emissions at mainland China airports from 1990 to 2017, mainly focusing on standard landing and take-off (LTO) cycles. Total flight movements increased 29-fold from 1990 to 2017 at Chinese airports. Over the same period, the emissions of NOx, SOx, CO, hydrocarbons (HC), and particulate matter (PM) increased 46, 27, 12, 5, and 4 times, respectively. Emissions at the 216 public airports showed a growth trend. It was estimated that in 2017, Chinese airports emitted 12,875 kilotons of CO2, 59 kilotons of NOx, 3 kilotons of SOx, 38 kilotons of CO, 5 kilotons of HC, and 0.4 kilotons of PM. The largest 30 airports produced 68.2% of the total emissions. Emissions from B737-800, A320, A321, B737-700, A330-300, and A319 aircraft accounted for more than 75% of aircraft LTO emissions at Chinese airports in 2017. Results show that average emissions per passenger have decreased for CO2, CO, HC, SOx, PM, and NOxfrom 1990 to 2017.

ABSTRACTBackground:The disease burden of infectious diarrhea cannot be underestimated. Its seasonal patterns indicate that weather patterns may play an important role and have an important effect on it. The objective of this study was to clarify the relationship between temperature and infectious diarrhea, and diarrhea-like illness.Methods:Distributed lag non-linear model, which was based on the definition of a cross-basis, was used to examine the effect.Results:Viral diarrhea usually had high incidence in autumn-winter and spring with a peak at -6°C; Norovirus circulated throughout the year with an insignificant peak at 8°C, while related bacteria usually tested positive in summer and peaked at 22°C. The lag-response curve of the proportion of diarrhea-like cases in outpatient and emergency cases revealed that at -6°C, with the lag days increasing, the proportion increased. Similar phenomena were observed at the beginning of the curves of virus and bacterial positive rate, showing that the risk increased as the lag days increased, peaking on days 16 and 9, respectively. The shape of lag-response curve of norovirus positive rate was different from others, presenting m-type, with 2 peaks on day 3 and day 18.Conclusion:Weather patterns should be taken into account when developing surveillance programs and formulating relevant public health intervention strategies.

AbstractNot all patients who acquire carbapenemase-producing Enterobacteriaceae (CPE) develop infections by these organisms; many remain only colonized. Of 54 CPE-colonized patients, 16 (30%) developed CPE infections. We identified indwelling urinary catheter exposure, exposure to intravenous colistin, and overseas transfer as variables associated with CPE infection development among colonized patients.
Ghana's petroleum industry: expectations, frustrations and anger in coastal communities

Published: November 2020

ABSTRACTWith much fanfare, Ghana's Jubilee Oil Field was discovered in 2007 and began producing oil in 2010. In the six coastal districts nearest the offshore fields, expectations of oil-backed development have been raised. However, there is growing concern over what locals perceive to be negative impacts of oil and gas production. Based on field research conducted in 2010 and 2015 in the same communities in each district, this paper presents a longitudinal study of the impacts (real and perceived) of oil and gas production in Ghana. With few identifiable benefits beyond corporate social responsibility projects often disconnected from local development priorities, communities are growing angrier at their loss of livelihoods, increased social ills and dispossession from land and ocean. Assuming that others must be benefiting from the petroleum resources being extracted near their communities, there is growing frustration. High expectations, real and perceived grievances, and increasing social fragmentation threaten to lead to conflict and underdevelopment.
