Erfolgreicher Wissensaustausch in virtuellen Teams – Wie wichtig ist soziale Präsenz?
Authors: Tietz Stephanie , Kneisel Evi , Werner Katja 
Published: October 2021

ZusammenfassungErfolgreicher Wissensaustausch ist ein zentraler Prozess für den Erfolg virtueller Teams. Damit gehen spezifische Herausforderungen einher. Die verwendete Informations- und Kommunikationstechnologien, die räumliche Trennung und der mangelnde persönliche Kontakt der Teammitglieder erschweren den Austausch von Wissen.Die Forschung zu Einflussfaktoren auf Wissensaustausch in virtuellen Umgebungen fokussiert zumeist rein technische oder soziale Faktoren. Dagegen kaum beachtet ist die Rolle der sozialen Präsenz als interdisziplinäres Konstrukt. Soziale Präsenz meint das subjektive Erleben eines Zusammengehörigkeitsgefühls trotz physischer Distanz, das in der Interaktion zwischen den Nutzern und der vorhandenen Technologie entsteht.Die vorliegende Studie untersuchte, inwieweit das Erleben sozialer Präsenz den Erfolg virtuellen Wissensaustausches beeinflusst. Basierend auf der Critical Incident Technique wurden 26 Interviews mit Mitgliedern virtueller Teams geführt. Die Teilnehmenden schilderten Situationen, in denen der virtuelle Wissensaustausch erfolgreich oder nicht erfolgreich war.Die Auswertung zeigt, dass soziale Präsenz häufiger in erfolgreichen Situationen auftrat. Das weist darauf hin, dass deren Erleben wichtig für erfolgreichen Wissensaustausch ist.Praktische Relevanz:Soziale Präsenz kann durch Medienreichhaltigkeit, Unterstützung sozialer Prozesse und Beziehungen in virtuellen Teams positiv beeinflusst werden. Aus den Ergebnissen lassen sich somit Implikationen für die Gestaltung, Moderation und Führung virtueller Zusammenarbeit ableiten.
Benefits of Bayesian Model Averaging for Mixed-Effects Modeling
Authors: Heck Daniel W. , Bockting Florence 
Published: October 2021

AbstractBayes factors allow researchers to test the effects of experimental manipulations in within-subjects designs using mixed-effects models. van Doorn et al. (2021) showed that such hypothesis tests can be performed by comparing different pairs of models which vary in the specification of the fixed- and random-effect structure for the within-subjects factor. To discuss the question of which model comparison is most appropriate, van Doorn et al. compared three corresponding Bayes factors using a case study. We argue that researchers should not only focus on pairwise comparisons of two nested models but rather use Bayesian model selection for the direct comparison of a larger set of mixed models reflecting different auxiliary assumptions regarding the heterogeneity of effect sizes across individuals. In a standard one-factorial, repeated measures design, the comparison should include four mixed-effects models: fixed-effects H0, fixed-effects H1, random-effects H0, and random-effects H1. Thereby, one can test both the average effect of condition and the heterogeneity of effect sizes across individuals. Bayesian model averaging provides an inclusion Bayes factor which quantifies the evidence for or against the presence of an average effect of condition while taking model selection uncertainty about the heterogeneity of individual effects into account. We present a simulation study showing that model averaging among a larger set of mixed models performs well in recovering the true, data-generating model.
Training Gaussian boson sampling by quantum machine learning
Authors: Conti Claudio 
Published: October 2021

AbstractWe use neural networks to represent the characteristic function of many-body Gaussian states in the quantum phase space. By a pullback mechanism, we model transformations due to unitary operators as linear layers that can be cascaded to simulate complex multi-particle processes. We use the layered neural networks for non-classical light propagation in random interferometers, and compute boson pattern probabilities by automatic differentiation. This is a viable strategy for training Gaussian boson sampling. We demonstrate that multi-particle events in Gaussian boson sampling can be optimized by a proper design and training of the neural network weights. The results are potentially useful to the creation of new sources and complex circuits for quantum technologies.
Young motherhood: levels and socioeconomic determinants of adolescent fertility in Ghana
Authors: Nyarko Samuel H. , Potter Lloyd 
Published: October 2021

AbstractAdolescent fertility levels have shown considerable improvements globally over the past decades. However, adolescent childbearing remains high in developing countries, particularly in sub-Saharan Africa. This study, thus, examines the levels and socioeconomic factors associated with adolescent fertility in Ghana. The study drew on data from the 2003, 2008, to the 2014 Ghana Demographic and Health Surveys to perform a logistic regression analysis of socioeconomic factors associated with adolescent fertility. The results show that adolescent childbearing levels have not shown any considerable improvements over the study periods (10%, 10%, and 11% for 2003, 2008, and 2014, respectively). Socioeconomic factors such as household wealth status, working status, employer status, and employment period were associated with adolescent fertility. Female adolescents from poor households, employed and self-employed adolescents, as well as regular workers, were linked to higher adolescent fertility risks. Older adolescents, and ever married adolescents also show significantly higher childbearing risks while the risk levels steadily increased over time. Promoting economic empowerment among female adolescents and targeting employed female adolescents in fertility control measures may have considerable positive implications for adolescent fertility levels in Ghana.
Super-resolution for doubly-dispersive channel estimation
Authors: Beinert Robert , Jung Peter , Steidl Gabriele , Szollmann Tom 
Published: October 2021

AbstractIn this work we consider the problem of identification and reconstruction of doubly-dispersive channel operators which are given by finite linear combinations of time-frequency shifts. Such operators arise as time-varying linear systems for example in radar and wireless communications. In particular, for information transmission in highly non-stationary environments the channel needs to be estimated quickly with identification signals of short duration and for vehicular application simultaneous high-resolution radar is desired as well. We consider the time-continuous setting and prove an exact resampling reformulation of the involved channel operator when applied to a trigonometric polynomial as identifier in terms of sparse linear combinations of real-valued atoms. Motivated by recent works of Heckel et al. we present an exact approach for off-the-grid super-resolution which allows to perform the identification with realizable signals having compact support. Then we show how an alternating descent conditional gradient algorithm can be adapted to solve the reformulated problem. Numerical examples demonstrate the performance of this algorithm, in particular in comparison with a simple adaptive grid refinement strategy and an orthogonal matching pursuit algorithm.
Whose pay should be cut in economic crises? Consumers prefer firms that prioritize paying employees over CEOs
Authors: Hagerty Serena F. , Mohan Bhavya , Norton Michael I. 
Published: October 2021

AbstractFour experiments examine the impact of a firm deciding to no longer pay salaries for executives versus employees on consumer behavior, particularly in the context of the COVID-19 pandemic. Study 1 explores the effect of announcing either pay cessations or continued pay for either CEO or employees, and shows that firms’ commitment to maintaining employee pay leads to the most positive consumer reactions. Study 2 examines the effects of simultaneously announcing employee and CEO pay cessations: consumers respond most positively to firms prioritizing employee pay, regardless of their strategy for CEO pay. Moreover, these positive perceptions are mediated by perceptions of financial pain to employees, more than perceptions of CEO-to-worker pay ratio fairness. Study 3, using an incentive-compatible design, shows that firms’ commitment to paying employees their full wages matters more to consumers than cuts to executive pay, even when those executive pay cuts lead to a lower CEO-to-worker pay ratio. Study 4 tests our account in a non-COVID-19 context, and shows that consumers continue to react favorably to firms that maintain employee pay, but when loss is less salient, consumers prioritize cutting CEO pay and lowering the CEO-to-worker pay ratio. We discuss the implications of our results for firms and policymakers during economic crises.
The role of family networks and social capital on women's fertility intentions in Ouagadougou, Burkina Faso
Authors: Bougma Moussa , Rossier Clémentine 
Published: October 2021

AbstractFamily solidarities remain strong in African societies. In Ouagadougou, transfers within extended family networks provide an omnipresent means for coping with life's difficulties, and the desired number of children remains relatively high. The role of family networks in maintaining high fertility is rarely studied however for lack of data in conventional demographic surveys. This study uses original retrospective data and logistic regression methods to explore the role of the extended family's social capital in shaping women's desire for children in Ouagadougou. Results show that women belong to three types of family networks: (1) women who belong to large family networks on both her own and her husband's side and who maintain a moderate number of close relations with their own relatives; (2) women who also belong to large family networks on both their and their husband's sides but who maintain a greater number of close relations with their own blood relatives; (3) unmarried women with relatives only on their side and numerous close relations with their family. Support for children's schooling comes more often from women's relatives in networks type 2 and 3, and from husbands' relatives in network type 1. Support for children's schooling increases with the level of economic resources in family networks (proxied by the presence of a public employee), in all network types. Women in type 2 networks (centered on women's relatives) are more likely to want additional children compared to women in type 1 networks (centered on their husband's relatives), after controlling for economic resources in networks. This result suggests that practical support provided by family members could play a role, on top of economic support, in encouraging high fertility in Ouagadougou.
Focus on biosensors: Looking through the lens of quantitative biology
Authors: Rowe James H. , Jones Alexander M. 
Published: October 2021

AbstractIn recent years, plant biologists interested in quantifying molecules and molecular events in vivo have started to complement reporter systems with genetically encoded fluorescent biosensors (GEFBs) that directly sense an analyte. Such biosensors can allow measurements at the level of individual cells and over time. This information is proving valuable to mathematical modellers interested in representing biological phenomena in silico, because improved measurements can guide improved model construction and model parametrisation. Advances in synthetic biology have accelerated the pace of biosensor development, and the simultaneous expression of spectrally compatible biosensors now allows quantification of multiple nodes in signalling networks. For biosensors that directly respond to stimuli, targeting to specific cellular compartments allows the observation of differential accumulation of analytes in distinct organelles, bringing insights to reactive oxygen species/calcium signalling and photosynthesis research. In conjunction with improved image analysis methods, advances in biosensor imaging can help close the loop between experimentation and mathematical modelling.
FTIR BONE CHARACTERIZATION AND RADIOCARBON DATING: TIMING THE ABANDONMENT OF BYZANTINE PIGEON TOWERS IN THE NEGEV DESERT, ISRAEL
Authors: Yan Xin , Tepper Yotam , Bar-Oz Guy , Boaretto Elisabetta 
Published: October 2021

ABSTRACTVarious archaeological and historical evidence shows that the marginal area of the Negev desert of southern Israel enjoyed great agricultural prosperity in the Byzantine period (4th–7th centuries CE). Among the different types of agricultural installations are pigeon towers, which were built near the fields to produce fertilizer to enrich the nutrient-poor desert soils. Such extensive specialized agriculture practice was much less applied in the Negev in the successive Early Islamic period in the mid-7th century. Here we recoveredin situpigeon bones from five pigeon towers in the Negev, applied multiple characterization methods (FTIR, grinding curve, and C/N ratio) to estimate the preservation of bones, and achieved absolute dating for the abandonment of the towers. The obtained dates indicate rapid decline of agricultural activities in the second half of the 6th century CE and beginning of the 7th century. These findings, together with other evidence for Byzantine decline of agricultural hinterland and urban dysfunction of the settlements, suggest that the farming activities in the Negev declined in the Late Byzantine period (550–640 CE) and support the hypothesis that climatic-driven causes were the main trigger for the eventual cultural-societal decline of the Negev region.
Thomas More and the Defence of the Religious Orders in Henry VIII's England
Authors: Heale Martin 
Published: October 2021

AbstractMuch has been written about Thomas More's alleged monastic vocation and spirituality, but rather less about his views on the religious orders of his day. This article argues that a consistent position towards contemporary English monasticism can be discerned across More's (highly varied) oeuvre and in his personal connections with religious houses. He was an enthusiastic supporter of strictly observant monasticism throughout his career, but seems to have looked much more critically upon other branches of the religious orders in early Tudor England (which comprised the large majority). This orientation was shared with some other English humanists, but clashed with the position of Erasmus who held no special regard for strictly observant monasteries. More's misgivings about general monastic standards in the realm held a wider significance, in view of his status as the most prolific and influential polemicist writing in support of the early Tudor church. The defence of the religious orders in the controversialist works that More wrote and oversaw in the later 1520s and early 1530s was distinctly lukewarm, and even at times evasive. Partly as a result, the mounting evangelical and anticlerical attacks on English monasteries in these years went largely unanswered.
Childbearing culture: a prominent context in the process of maternal role attainment in Iranian mothers with preterm neonates
Authors: Alinejad-Naeini Mona , Peyrovi Hamid , Shoghi Mahnaz 
Published: October 2021

AbstractTransition to the role of mothering is one of the most important events in a woman’s life. While childbirth is a biological event, pregnancy and the experiences around it are more influenced by social structure, which is shaped by cultural perceptions and practices. The aim of this study was to explore cultural context during maternal role attainment in neonatal intensive care units (NICUs) in Iran. The study was part of a grounded theory study on how the mothers of preterm neonates go through maternal role attainment. Data collection was carried out by purposeful sampling from 20 participants (15 mothers of preterm neonates and 5 NICU nurses). Data were analysed according to Corbin and Strauss’s (2015) approach. Four categories of childbearing culture emerged: ‘The necessity of childbearing’, ‘Childbearing rituals’, ‘Maternal persistent presence’ and ‘Attitudes and religious beliefs’. The findings showed that the special beliefs and practices in Iranian culture affected all of the participants’ reactions to mothering process. Culture is one of the most important factors affecting the development of motherhood in Iran. In order to provide sensitive and culturally appropriate care, nurses should be aware of the general impact of cultural norms and values on the process of maternal role attainment and strive to meet the cultural needs of all mothers.
The Asian fish tapeworm (Schyzocotyle acheilognathi) discovered in Western Australia may pose a threat to the health of endemic native fishes

AbstractThe Asian fish tapeworm (Schyzocotyle acheilognathi) is an important fish parasite with a wide host range that infects over 300 species of fish worldwide.Schyzocotyle acheilognathihas been reported from eastern coastal areas of Australia, but has not been previously reported in Western Australia (WA). During a control program for invasive freshwater fishes in south-western WA, a region with a unique and highly endangered freshwater fish fauna, tapeworms identified asS.acheilognathifrom their distinctive scolex morphology were found at a prevalence of 3.3% in goldfish (Carassius auratus), 37.0% in koi carp (Cyprinus carpio haematopterus) and 65.0% in eastern gambusia (Gambusia holbrooki) in a small suburban lake to the north of Perth. For molecular confirmation, the 18S ribosomal RNA gene was targeted at hypervariable V4 region. Koi carp isolates were 100% identical toS.acheilognathiisolated from varying hosts, including the red shiner (Cyprinella lutrensis) and a human sample. Sequences obtained from two eastern gambusia were identified asS.acheilognathi, but formed a discrete cluster and may represent a novel genotype. Isolates from two other eastern gambusia and two goldfish formed a distinct clade with only 91.9% similarity to previously sequenced isolates ofS.acheilognathi. This emphasizes the importance of molecular identification methods in addition to morphological identification. The presence and potential for transmission of these parasites in south-western WA may threaten the health of native fishes, which are immunologically naïve to this introduced parasite. Immediate control or containment measures should be implemented to halt the spread of these parasites.
Subperiosteal inferior maxillectomy in mucormycosis patients: case series
Authors: Wadhwa V , Chaudhary D , Meher R , Rathore P K , Kumar V , Soni S , Kumar N 
Published: October 2021

AbstractObjectiveMucormycosis is a rapidly progressive and fulminant fungal infection mainly affecting the nose and paranasal sinuses and often requiring aggressive surgical debridement, which commonly includes inferior maxillectomy. Conventional inferior maxillectomy involves removal of the bony hard palate and its mucoperiosteum. This can lead to formation of an oroantral fistula and thereby increase the morbidity in these patients leading to prolonged rehabilitation. Subperiosteal inferior maxillectomy involves sparing of the uninvolved mucoperiosteum of the hard palate. This flap is used for closure of the oroantral fistula, which preserves the functional capabilities of the patient, such as speech, mastication and deglutination.MethodThis case series describes the experience of using the technique of mucosa-preserving subperiosteal inferior maxillectomy in five patients with mucormycosis.ResultsWith the technique used in this study, complete oronasal separation was achieved in all six patients. The overall surgery time was also decreased when compared with free tissue transfer. Patients also did not have to bear the weight of prosthesis.ConclusionMucoperiosteal palatal flap-preserving subperiosteal inferior maxillectomy is an excellent approach for all patients with mucormycosis and healthy palatal mucosa.
Structuring complexity? A systemic perspective on the implementation of a disease management programme for type II diabetes care in Denmark
Authors: Vrangbæk Karsten 
Published: October 2021

AbstractChronic diseases are major causes of death and reduction in the quality of life worldwide, and their prevalence is expected to rise due to changing demographics. Disease management programmes (DMPs) have been presented as a policy response to challenges of care coordination for such chronic diseases. This paper investigates the implementation of DMPs in a National Health Care system in the Nordic region using type II diabetes as an example. DMPs are detailed descriptions of the sequence and responsibilities for diagnostic, treatment, rehabilitation and prevention procedures. The paper applies a systemic implementation perspective to provide detailed analysis of implementation progress, issues and concerns. The implementation analysis shows that the framework of DMP has facilitated the development of new practices and attention to the roles that each of the stakeholders are playing within the service delivery. Many new initiatives contribute to improved coordination and overall management of the Type 2 diabetes (T2DB) population. Yet, there are also several cross-cutting challenges that are affecting the implementation process.
Guilt by association: Restricting humanitarian assistance in the name of counterterrorism
Authors: Pozo Marín Alejandro , Ben Ali Rabia 
Published: October 2021

AbstractIn certain contexts associated with counterterrorism, some governments and military forces have stigmatized civilians, not because of the acts they perform but rather from loose associations with groups perceived as “terrorists”, based on geographical proximity or common social, ethnic and religious backgrounds. Access to humanitarian assistance has been affected by this stigmatization, and in specific geographical areas it has been blocked, restricted, made conditional or undermined. This article draws on recent literature and examples to argue that certain counterterrorism frameworks and practices have inhibited the impartial delivery of aid to all affected populations.

AbstractThe Australian 2019/2020 bushfires were unprecedented in their extent and intensity, causing a catastrophic loss of habitat, human and animal life across eastern‐Australia. We use a regional air quality model to assess the impact of the bushfires on particulate matter with a diameter less than 2.5 μm (PM2.5) concentrations and the associated health impact from short‐term population exposure to bushfire PM2.5. The mean population Air Quality Index (AQI) exposure between September and February in the fires and no fires simulations indicates an additional ∼437,000 people were exposed to “Poor” or worse AQI levels due to the fires. The AQ impact was concentrated in the cities of Sydney, Newcastle‐Maitland, Canberra‐Queanbeyan and Melbourne. Between October and February 171 (95% CI: 66–291) deaths were brought forward due to short‐term exposure to bushfire PM2.5. The health burden was largest in New South Wales (NSW) (109 (95% CI: 41–176) deaths brought forward), Queensland (15 (95% CI: 5–24)), and Victoria (35 (95% CI: 13–56)). This represents 38%, 13% and 30% of the total deaths brought forward by short‐term exposure to all PM2.5. At a city‐level 65 (95% CI: 24–105), 23 (95% CI: 9–38) and 9 (95% CI: 4–14) deaths were brought forward from short‐term exposure to bushfire PM2.5, accounting for 36%, 20%, and 64% of the total deaths brought forward from all PM2.5. Thus, the bushfires caused substantial AQ and health impacts across eastern‐Australia. Climate change is projected to increase bushfire risk, therefore future fire management policies should consider this.
