Kontakte mit Nichten und Neffen – Eine empirische Analyse von vernachlässigten Verwandtschaftsbeziehungen
Authors: Jakoby Nina 
Published: March 2021

This article predicts the frequency of aunts’ and uncles’ contacts with their nieces and nephews. I develop a new theoretical framework to explain differences in contact frequency, using data from ISSP 2001 (Social Networks II). The empirical results reveal that classic variables (e.g. gender, social status, childlessness) have no influence on contact frequency with nieces and nephews, contrary to existing literature. Future studies would benefit from biographical predictors in understanding these important and understudied family relationships.
Zusammenfassung
Dieser Beitrag untersucht die Häufigkeit der sozialen Kontakte von Onkeln und Tanten mit ihren Nichten und Neffen. Damit wird eine Verwandtschaftskategorie analysiert, die in der Familiensoziologie eine fast vergessene Thematik ist. Auf der Grundlage eines theoretischen Modells und einer daran anschließenden empirischen Analyse mit Daten des ISSP 2001 (Social Networks II) werden die Determinanten der Kontakthäufigkeit mit Nichten und Neffen analysiert. Die Ergebnisse zeigen, dass eine Vielzahl der Befunde zu den klassischen Determinanten verwandtschaftlicher Interaktionen (z.B. Geschlecht, sozialer Status, Kinderlosigkeit) nicht repliziert werden kann. Eine stärkere Berücksichtigung der Familienbiographie sollte Ziel einer zukünftigen soziologischen Verwandtschaftsforschung sein.
The role of job-related spatial mobility in the household division of labor within couples in Germany and Poland
Authors: Hofmeister Heather , Hünefeld Lena , Proch Celina 
Published: March 2021

This paper will examine the self-reported division of housework and childcare in Germany and Poland considering the job-related spatial mobility within dual-earner couples who are living in a household together with a partner, using 2007 data from the Job Mobility and Family Lives in Europe Project. We find that men who are spatially mobile for work often report shifting housework to their partners. Polish couples show a stronger tendency toward an egalitarian division of labor than German couples do, especially in terms of childcare. But the central finding of this research is, gender trumps national differences and spatial mobility constraints. Polish and German women, whether mobile for their work or not, report doing the majority of housework and childcare compared to their partners.
Zusammenfassung
Dieser Artikel untersucht die Aufteilung von Hausarbeit und Kinderbetreuung auf Basis von Selbsteinschätzungen berufsbedingt räumlichmobiler sowie nicht mobiler Befragter in Deutschland und Polen. Anhand von Daten des Projektes Job Mobility and Family Lives in Europe (2007) betrachten wir Personen, die mit ihrem Partner in einem Doppelverdienerhaushalt leben. So geben beruflich mobile Männer häufig an, die Hausarbeit auf ihre Partner zu übertragen. Polnische Paare zeigen eine stärkere Tendenz zu einer egalitären Arbeitsteilung als deutsche, insbesondere im Hinblick auf die Kinderbetreuung. Das zentrale Ergebnis unserer Untersuchung ist jedoch, dass das Geschlecht sowohl Mobilitäts- als auch nationale Unterschiede überlagert. Sowohl polnische als auch deutsche Frauen, ob beruflich mobil oder nicht, übernehmen den Hauptanteil an der Hausarbeit und Kinderbetreuung.
Geographic job mobility and parenthood decisions
Authors: Meil Gerardo 
Published: March 2021

The aim of this paper is to analyse, differentiated by gender, the effects that high geographical job mobility has on parenthood decisions. In particular, in a first part we will examine whether job mobility fosters childlessness and/or postponement of childbearing and if mobility implies a lower family size. In a second part we will analyse how the specific working conditions of mobile people and their resources for balancing working and private lives affect childlessness and postponement of parenthood. The analysis will be based on a representative survey of people aged 25 to 54, performed in six European countries (Germany, France, Spain, Poland, Switzerland and Belgium) in 2007, oversampling mobile people in order to get enough cases to analyse. Results show that the impact of high job mobility on the timing and quantum of parenthood is important, both for men and women, but stronger for the latter. Besides gender, the strength of the impact depends on the duration of job mobility and when it takes place in the lifecycle. Resources for promoting a better balance of working and private lives such as flexitime and teleworking have no clear impact on parenthood decisions, but having a supportive employer facilitates family development of mobile employees. A greater involvement of men in unpaid work does not seem to facilitate fertility decisions of mobile women.
Zusammenfassung
In diesem Beitrag wird der Frage nachgegangen, inwieweit hohe berufsbedingte räumliche Mobilität negative Folgen auf die Familienentwicklung hat. Im ersten Teil des Aufsatzes wird getrennt nach Geschlecht analysiert, ob Mobilität Kinderlosigkeit fördert, eine Verschiebung des Geburtenkalenders verursacht und ob sie eine Reduktion der Familiengröße zur Folge hat. Darüber hinaus wird in dem zweiten Teil analysiert, welchen Einfluss bestimmte Arbeitsbedingungen sowie die Ressourcen, die Familien zur Verfügung stehen, um Familie und Beruf zu vereinbaren, auf die Entscheidungen bezüglich Elternschaft ausüben. Die Analyse stützt sich auf eine repräsentative Umfrage in sechs europäischen Ländern (Deutschland, Frankreich, Spanien, Polen, Schweiz und Belgien) mit Personen im Alter zwischen 25 und 54 Jahren. Die Daten wurden in 2007 erhoben. Mobile Erwerbstätige wurden überproportional erhoben, um eine ausreichende Fallzahl zu gewährleisten. Die Ergebnisse zeigen, dass die Auswirkung der Mobilität auf die Familienentwicklung von Bedeutung ist, wobei sich Mobilität von Frauen stärker auswirkt. Darüber hinaus ist von Bedeutung, wann im Lebenslauf Mobilität und Elternschaft stattfinden und wie lange die Phase der mobilen Arbeit andauert. Flexible Arbeitszeiten oder die Möglichkeit, einen Teil der Arbeit zu Hause zu leisten, haben keinen eindeutigen Einfluss auf die Entscheidungen zur Elternschaft von mobilen Erwerbstätigen, wohl aber die Unterstützung durch den Arbeitgeber. Unterstützung seitens des Partners scheint die Entscheidung mobiler Frauen für Kinder nicht zu fördern.
Entwicklung eines neuen multidimensionalen Fragebogens zur Erfassung der Partnerschaftsqualität (FPQ)
Authors: Siffert Andrea , Bodenmann Guy 
Published: March 2021

Background: Research on couples is receiving increased attention. There are some questionnaires assessing relationship quality available in German. However, they are not assessing all relevant dimensions of relationship quality. Therefore, an alternative questionnaire to measure relationship quality (FPQ) is presented in this study. Methods: The measure was tested with a total of 244 adults, who were all in a close relationship at that time. The dimensional structure was tested with exploratory and confirmatory factor analyses. Results: Scale analyses revealed a questionnaire consisting of six subscales (fascination, commitment, sexuality, future of the partnership, mistrust, and constraint autonomy). The internal scale consistencies vary between .78 and .92. Additionally, by using structural equation modeling, a superior factor relationship quality was found. The discriminative validity was confirmed by a group comparison (satisfied and unsatisfied people). Moderate to high correlations with a traditional questionnaire measuring relationship quality and other relevant constructs indicate satisfying convergent validity.
Zusammenfassung
Hintergrund: Im deutschen Sprachraum kommt der Partnerschaftsforschung zusehends mehr Gewicht zu. Zwar gibt es im deutschsprachigen Raum einige Fragebögen zur Messung der Partnerschaftsqualität, diese erfassen aber nicht alle relevanten Dimensionen. Deshalb wird in der vorliegenden Studie als Ergänzung zu den bisherigen Fragebögen ein neues Instrument zur Messung der Partnerschaftsqualität (FPQ) vorgestellt. Methodik: Der Fragebogen wurde an einer Stichprobe von 244 Personen getestet, die sich zum Zeitpunkt der Erhebung in einer Partnerschaft befanden. Die dimensionale Struktur wurde mittels explorativer und konfirmatorischer Faktorenanalysen geprüft. Ergebnisse: Die faktorielle Validitätsprüfung ergab einen Fragebogen bestehend aus sechs Subskalen (Faszination, Engagement für die Beziehung, Sexualität in der Beziehung, Zukunftsperspektive der Beziehung, Misstrauen gegenüber dem Partner und Einschränkung der Freiheit/Unabhängigkeit). Die interne Konsistenz der sechs Subskalen liegt zwischen .75 und .94. Zusätzlich liess sich ein übergeordneter Faktor Partnerschaftsqualität konstruieren. Die diskriminative Validität wurde durch einen Gruppenvergleich (zufriedene und unzufriedene Personen) bestätigt. Die moderaten bis hohen Korrelationen des neuen Fragebogens mit dem Partnerschaftsfragebogen PFB zur Messung der Partnerschaftsqualität und anderen relevanten Konzepten unterstützen die konvergente Validität.
Patterns of immigrant intermarriage in France: Intergenerational marital assimilation?
Authors: Safi Mirna 
Published: March 2021

This article provides insight into immigrant intermarriage in France. It describes trends of immigrant marital behaviour between 1976 and 2000, compares intermarriage rates amongst different immigrant groups and pays particular attention to changes in marital behaviour across immigrant generations. The statistical analyses take into account individual factors and contextual effects such as the sex-ratios and sizes of the groups in question. Based on data from the Échantillon démographique permanent (Permanent Demographic Sample, EDP) of the Institut National de la Statistique et des Études Économiques (INSEE), findings point to a stable trend of marital behaviour among immigrant men and women over time, sharp differences in intermarriage rates among groups, and a significant change in the marital behaviour of secondgeneration immigrants, who intermarry much more often than their parents regardless of their origin.
Zusammenfassung
Dieser Beitrag gibt Einblick in interethnische Eheschließungen in Frankreich. Es werden Trends des Heiratsverhaltens von Immigrant(inn)en in den Jahren 1976 und 2000 in Frankreich beschrieben, interethnische Eheschließungsraten bei verschiedenen Immigrantengruppen miteinander verglichen, wobei ein besonderes Augenmerk auf Veränderungen im Heiratsverhalten über die Einwanderergenerationen hinweg gerichtet wird. Bei den statistischen Analysen werden sowohl individuelle Faktoren als auch Kontexteffekte, wie z.B. das Geschlechterverhältnis und die Gruppengröße der betreffenden Gruppen, einbezogen. Auf Basis der Daten des Échantillon démographique permanent (demographische Dauerstichprobe) des Institut National de la Statistique et des Études Économiques (INSEE) deuten die Ergebnisse darauf hin, dass es einen über die Zeit stabilen Trend beim Heiratsverhalten von Männern und Frauen mit Migrationshintergrund, sehr deutliche Unterschiede in den interethnischen Eheschließungsraten zwischen den Einwanderergruppen sowie signifikante Veränderungen im Heiratsverhalten der zweiten Generation der Einwanderer gibt. Letztere gehen – unabhängig von ihrer Herkunft – sehr viel häufiger interethnische Ehen als noch ihre Eltern ein.

Published: March 2021

Traditional application of plant in folk medicine is a base for discovery of new active chemical substances. In the second half of 20th century, significant antitumor activity of extract from bark of the Yew tree was recognized. The compound that was responsible for this kind of properties has called taxol and had structure of diterpene with acyl groups. Low availability forced researchers to find different ways of taxol gaining. In the further years, many synthetic and semi-synthetic methods were developed. Nowadays, biotechnological methods with use of cell suspension cultures are introduced.

Angiotensin converting enzyme inhibitors have emerged as a useful strategy in the management of hypertension and other cardiovascular system-related diseases. However, a wide range of their biological effects has turned the scientific interest towards other possible clinical applications of these drugs. The present review demonstrates the available data on the reported angiotensin-converting enzyme inhibitors – based therapies in the treatment of the following human disturbances: cancer, obesity, Barrett syndrome, erythrocytosis, a high-dose-chemotherapy-induced cardiotoxicity, Marfan syndrome, Duchenne muscular dystrophy, migraine, Raynaud’s syndrome and Alzheimer disease.
The history of the Human Immunodeficiency Virus research

Published: March 2021

The authors summarize the current knowledge of the beginnings of the human immunodeficiency virus (HIV) infections. Most of the studies have so far supported the theory that HIV infections had in their initial years been a typical zoonosis which had been present among African tribes for over 300 years. Most likely, infection was transferred from monkeys, particularly from chimpanzees, on multiple occasions. The most recent publications allow us to describe the transfer of the virus into humans, and new epidemiological data allow us to carry out analysis of the global spread of the virus. Studies of histopathological samples taken from patients in the 1960s have cast new light on the issue of virus presence in the US population, and the previous theories tracking the beginning of infections to the 1980s have had to be modified. Greater awareness of pandemic mechanisms should allow for more effective future counteraction of the spread of new pathogens.

Monogenic diabetes – an unappreciated problem among physicians
Authors: Niechciał Elżbieta , Skowrońska Bogda , Gertig-Kolasa Anna , Krzyśko Izabela , Fichna Piotr 
Published: March 2021

Monogenic diabetes results from one or more mutations in a single gene. It is a relatively rare genetic condition, therefore, it was frequently unappreciated among clinicians. Consequently, monogenic diabetes is misdiagnosed as type 1 diabetes or type 2 diabetes. Such misclassification leads to an inappropriate treatment, often inconvenient for the patients, such as insulin injections with their permanent glycemic control. The correct diagnosis may completely change previous methods of treatment. Patients diagnosed with GCK mutations may be completely treated with adequate diet. HNF1A/HNF4A affected patients are extremely sensitive to low dose sulphonylureas. Moreover, the exact diagnosis has an impact on patients’ relatives. Mostly, misdiagnosing of monogenic diabetes is caused by its rare occurrence and insufficient training in this area among physicians. According to different studies it may comprise 1–4% of all cases of diabetes. The aim of this article is to emphasize that despite the fact that monogenic diabetes is an uncommon disease, it should always be considered in cases of diabetes with unusual course.

Authors: Gupta Rohit Kumar , Pannu Praduman , Misra Rajiv 
Published: March 2021

Abstract
The 5G Network Slicing with SDN and NFV have expended to support new-verticals such as intelligent transport, industrial automation, remote healthcare. Network slice is intended as parameter configurations and a collection of logical network functions to support particular service requirements. The network slicing resource allocation and prediction in 5G networks is carried out using network Key Performance Indicators (KPIs) from the connection request made by the devices on joining the network. We explore derived features as the network non-KPI parameters using the k-Nearest Neighbor (kNN) graph construction. In this paper, we use kNN graph construction algorithms to augment the dataset with triangle count and cluster coecient properties for ecient and reliable network slice. We used deep learning neural network model to simulate our results with KPIs and KPIs with non-KPI parameters. Our novel approach found that at k=3 and k=4 of the kNN graph construction gives better results and overall accuracy is imroved around 29%.
Realization of Filter/Inverse Filter Topologies using single FTFNTA
Authors: Singh Ravendra , Prasad Dinesh 
Published: March 2021

Abstract

In this manuscript, two different topologies are presented for the realization of a conventional filter/inverse filter using the Four Terminal Floating Nullor Transconductance Amplifier (FTFNTA). The first topology can synthesize the inverse low-pass (ILP), inverse high-pass (IHP), and inverse band-pass (IBP) filter with applicable impedance choices. Subsequently, another topology that can synthesize conventional low-pass (LP), and band-pass (BP) active filter, as well as inverse high-pass (IHP), and inverse band-pass (IBP) filter from the same circuit topology with a viable solution of impedances as resistor/capacitor. To verify the workability of both topologies, SPICE simulation is performed using 180nm CMOS TSMC technology.
An Improved and Low-dimensional Fingerprint-based Localization Method in Collocated Massive MIMO-OFDM Systems
Authors: Moosavi Seyedeh Samira , Fortier Paul 
Published: March 2021

Abstract
Localization has drawn significant attention in 5G due to the fast-growing demand for location-based service (LBS). Massive multiple-input multiple-output (M-MIMO) has been introduced in 5G as a powerful technology due to its evident potentials for communication performance enhancement and localization in complicated environments. Fingerprint-based (FP) localization are promising methods for rich scattering environments thanks to their high reliability and accuracy. The Gaussian process regression (GPR) method could be used as an FP-based localization method to facilitate localization and provide high accuracy. However, this method has high computational complexity, especially in large-scale environments. In this study, we propose an improved and low-dimensional FP-based localization method in collocated massive MIMO orthogonal frequency division

multiplexing (OFDM) systems using principal component analysis (PCA), the affinity propagation clustering (APC) algorithm, and Gaussian process regression (GPR) to estimate the user's location. Fingerprints are first extracted based on instantaneous channel state information (CSI) by taking full advantage of the high-resolution angle and delay domains. First, PCA is used to pre-process data and reduce the feature dimension. Then, the training fingerprints are clustered using the APC algorithm to increase prediction accuracy and reduce computation complexity. Finally, each cluster's data distribution is accurately modelled using GPR to provide support for further localization. Simulation results reveal that the proposed method improves localization performance significantly by reducing the location estimation error. Additionally, it reduces the matching complexity and computational complexity.
