Business Model Innovation Through the Lens of Time: An Empirical Study of Performance Implications Across Venture Life Cycles
Authors: Freisinger Elena , Heidenreich Sven , Landau Christian , Spieth Patrick 
Published: October 2021

AbstractCurrent literature suggests that the innovation of a business model is among the most important success factors for organizations and has a positive influence on their performance. What is not yet clear, however, is how this relationship unfolds during an organization’s life cycle. We posit that business model innovation strongly contributes to firm performance in earlier phases, but ultimately gets less important. We therefore collected data on 250 organizations in Germany and used structural equation modeling for analytical purposes. We make the following two main contributions to the literature: (1) We confirm recent findings about the positive impact of business model innovation on performance; (2) we provide first empirical evidence for the important role of life cycle stages as moderator with regard to this relationship. With respect to the latter, our findings show that business model innovation is an important pathway of organizations, especially in their early years of existence, yet somewhat diminishing over time. In conclusion, this study opens new research avenues by extending and incorporating explanations for the life cycle theory and business model innovation.
The grass versus the people: sacred roots of environmental conflict in the Chilonga communal lands in Zimbabwe
Authors: Tarusarira Joram 
Published: October 2021

AbstractThis article analyses a conflict that erupted in 2021 between the government of Zimbabwe and the people of Chilonga in the south of the country over the expropriation of their ancestral for the production of lucerne grass. The people of Chilonga resisted being displaced from land to which they are deeply attached and have a sacred connection. This conflict provides a rare opportunity to analyze the often marginalized, muted and misunderstood sacred roots of the environmental conflict that shape collective agency. The article uses the concepts of emplacement and disemplacement to comprehend the deeper and more intangible impacts of displacing people from their grazing lands, sources of water and traditional herbs and medicines, and sacred sites—natural resources they claim to be sacred. Thus, while disemplacement has been used to explain why people find themselves moving, the article uses it to show the opposite: why they resist moving and demonstrate the not easily measured losses upon which resistance to moving hinges.
Fixing Up Waco, Texas: Populäre Religion, das Sentimentale und die Refiguration von Räumen
Authors: Steets Silke 
Published: October 2021

ZusammenfassungDer Text untersucht aktuelle religiöse Transformationsprozesse in der texanischen Stadt Waco als räumlich-kommunikative Refiguration. Ausgangspunkt ist der durchschlagende TV-Erfolg der Hausrenovierungsshow Fixer Upper, die in Waco spielt, in bislang fünf Staffeln bis zu 75 Millionen Zuschauer:innen fand und vor Ort einen Tourismusboom auslöste, der zu einem erstaunlichen Imagewandel der Stadt beitrug. Auf der Grundlage ethnographischer Beobachtungen und Interviewdaten sowie einer umfassenden Dokumentenanalyse rekonstruiert der Text schrittweise eine neue popkulturell-touristische Kommunikationsform des Religiösen, die unterschiedliche Formate annehmen kann – von der TV Show bis zur Stadtführung. Geprägt ist diese Kommunikationsform erstens durch ein evangelikales Erneuerungsnarrativ, zweitens durch die rituelle Herstellung und das materielle Wirklichwerden einer sentimentalen Neuordnung von Räumen und drittens durch die Ästhetisierung der evangelikalen Missionierungskommunikation. Sie setzt einen Wandlungsprozess in Gang, bei dem sich Raum und Religion wechselseitig bedingen: Einerseits wird der Raum zum zentralen Medium der religiösen Kommunikation, andererseits fungiert die Religion als identitätsstiftender Bezugspunkt spätmoderner Raumkonstruktionen. Die Analyse macht schließlich deutlich, dass sich im Raum ein Ringen um Aufmerksamkeit und Macht entfaltet, das sich als Resultat einer Spannung zwischen Bahnenraum und Ort und damit als Refiguration von Räumen deuten lässt.
Plotless actions with nevertheless a plot: the assemblage of a hybrid learning environment
Authors: Simon Frits , Vreuls Joyce 
Published: October 2021

AbstractWe report research into the evolvement of a hybrid learning environment where education, companies and government successfully cooperate. This hybrid learning environment—one of the latest inventions in curriculum design—is special because it was neither intended nor planned by the parties involved. With some self-astonishment, the participants in this research experienced a growing acknowledgement of their emerging educational creation, aside from the experience of and appreciation for their cooperation and the increasing turnover. With a bricolage research approach within the scope of a rhizomatic perspective on becoming, a multivocal perspective on the evolvement of the learning environment was pursued. In emphasizing the historical evolvement of the learning environment, our findings challenge the tradition of drawing board design, accompanied by an appeal for re-appreciating professional craftsmanship. In addition, some reflections regarding the research are discussed.
The changing language of women on The Big Bang Theory
Authors: Dennin Kimberly 
Published: October 2021

AbstractThis study focuses on how linguistic markers are utilized by women in media to highlight stereotypes and reinforce systems of oppression. Using data from the popular television program The Big Bang Theory, the speech patterns of the three main female characters, Penny, Amy, and Bernadette, were analyzed. It was found that changes in the speed and pitch of the dialog delivered by these characters correlated with the characters enacting certain female stereotypes that are not at the forefront of their personalities. The stereotypes of the traditionally feminine woman, overly aggressive woman, and ditzy blond are key in maintaining the inferior status of women. The stereotype of the traditionally feminine woman serves as an example of how women are supposed to act out their female identity, the overly aggressive stereotype is a warning against utilizing emotions outside of a traditional feminine community of practice, and the ditzy blond stereotype is used to provide proof of the inferiority of women and justify the continued subjugation of them.
Perianal endometriosis: An unusual cause of perianal pain
Authors: Lee J.W.K. , Tang Sarah S. , Ong J.L. , Oh H.B. , Lieske Bettina 
Published: October 2021

AbstractEndometriosis is a common clinical condition where functional endometrial tissue is found outside the uterine cavity. Although most of this ectopic tissue tends to occur within the pelvis, on rare occasions, they can also be found in unusual locations, such as the thoracic cavity, perianal, episiotomy scar, and previous abdominal wound sites. This is a case report of a healthy 41-year-old Chinese female who presented with a painful perianal lump which was subsequently investigated and excised. The diagnosis of perianal endometriosis was made upon histological examination of the tissue. Many theories attempt to explain the phenomenon of endometriosis in the perianal region. In this case, the implantation theory is the likely explanation as the patient had a significant history of 3 normal vaginal deliveries which were followed by episiotomies. Advancements in endo-anal ultrasound (EAUS) have aided in the planning of surgery for this lesion.
Flow simulation of the flight manoeuvres of a large transport aircraft with load alleviation
Authors: Breitenstein C. , Radespiel R. 
Published: October 2021

AbstractA new method for predicting manoeuvre loads on a large transport aircraft with a swept-back wing and a load alleviation system based on control surface deflections is developed. For this purpose, three-dimensional Reynolds-averaged Navier–Stokes (RANS) simulations of the rigid wing–fuselage configuration are performed while the aerodynamics of the tailplane are estimated by means of handbook methods. For a closer analysis, different quasi-steady pitching manoeuvres are chosen based on the CS-25 regulations. One of these manoeuvres is also simulated with active load alleviation, leading to a reduction in the wing-root bending moment by more than 40%. Besides demonstrating the potential of the considered load alleviation system, it is shown which manoeuvres are especially critical in this context and which secondary effects come along with load alleviation.
A method for robust design in a coupled decision environment
Authors: Sharma Gehendra , Allen Janet K. , Mistree Farrokh 
Published: October 2021

Abstract
The design of a connected engineered system requires numerous design decisions that influence one another. In a connected system that comprises numerous interacting decisions involving concurrency and hierarchy, accounting for interactions while also managing uncertainties, it is imperative to make robust decisions. In this article, we present a method for robust design using coupled decisions to identify design decisions that are relatively insensitive to uncertainties. To account for the influence among decisions, design decisions are modelled as coupled decisions. They are defined using three criteria: the types of decisions, the strength of interactions and the decision levels. In order to make robust decisions, robust design methods are classified based on sources of uncertainty, namely, Type I (noise factors), Type II (design variables) and Type III (function relationship between design variables and responses). The design of a one-stage reduction gearbox is used as a demonstration example. To illustrate the proposed method for robust design using coupled decisions, we present the simultaneous selection of gear material and gearbox geometry in a coupled decision environment while managing the uncertainties involved in designing gearboxes.
Equidistribution of horospheres in non-positive curvature
Authors: BURNIOL CLOTET SERGI 
Published: October 2021

AbstractWe study the ergodic properties of horospheres on rank 1 manifolds with non-positive curvature. We prove that the horospheres are equidistributed under the action of the geodesic flow towards the Bowen–Margulis measure, on a large class of manifolds. In the case of surfaces, we define a parametrization of the horocyclic flow on the set of horocycles containing a rank 1 vector that is recurrent under the action of the geodesic flow. We prove that the horocyclic flow in restriction to this set is uniquely ergodic. The results are valid for large classes of manifolds, including the compact ones.
A systematic review update of athletes’ nutrition knowledge and association with dietary intake
Authors: Janiczak Amy , Devlin Brooke L. , Forsyth Adrienne , Trakman Gina Louise 
Published: October 2021

AbstractAthletes’ dietary intakes sometimes do not meet sports nutrition guidelines. Nutrition knowledge (NK) is one factor that may influence dietary intake, but NK measurement tools are often outdated or unvalidated, and results regarding athletes’ NK are equivocal. The aims of this systematic review were to update previous systematic reviews by examining athletes’ NK and to assess the relationship between athletes’ general NK, sport NK and dietary intake. MEDLINE, CINAHL, Scopus, SPORTDiscus, Web of Science and Cochrane were searched for studies published between November 2015 and November 2020 that provided a quantitative measure of NK and described the NK tool used. Twenty-eight studies were included, study quality was assessed using JBI checklists and data on NK score and diet intake was extracted. Eight studies utilised validated, up-to-date NK measurement tools. Mean general and sport NK% scores varied between 40·2% ± 12·4 and 70 % ± 9. Mean protein and carbohydrate consumption was 1·1–3·4 g/kg.bw/d and 2·4–4·6 g/kg.bw/d, respectively. Weak-to-moderate, positive associations were found between NK and positive dietary behaviours. Due to a wide variety of NK measurement tools used, it is difficult to synthesise results to determine overall NK in athletes. Overall, there appears to be a low standard of knowledge. Quality of measurement tools for NK has improved but remains an issue. Future studies should use relevant, current validated NK tools or validate tools in their study population. More research is needed into the relationship between NK and other modifiable factors influencing dietary intake.

Published: October 2021

AbstractObjectiveThis study aimed to investigate the effects of automated metrics-based summative feedback on performance, retention and cognitive load in distributed virtual reality simulation training of mastoidectomy.MethodTwenty-four medical students were randomised in two groups and performed 15 mastoidectomies on a distributed virtual reality simulator as practice. The intervention group received additional summative metrics-based feedback; the control group followed standard instructions. Two to three months after training, participants performed a retention test without learning supports.ResultsThe intervention group had a better final-product score (mean difference = 1.0 points; p = 0.001) and metrics-based score (mean difference = 12.7; p < 0.001). At retention, the metrics-based score for the intervention group remained superior (mean difference = 6.9 per cent; p = 0.02). Also at the retention, cognitive load was higher in the intervention group (mean difference = 10.0 per cent; p < 0.001).ConclusionSummative metrics-based feedback improved performance and lead to a safer and faster performance compared with standard instructions and seems a valuable educational tool in the early acquisition of temporal bone skills.
Breeding of Cory's shearwaterCalonectris borealison Selvagem Grande and beneficial effects of removal of invasive mammals
Authors: Zino F. , Biscoito M. , Buckle A. 
Published: October 2021

AbstractThe largest colony of Cory's shearwaterCalonectris borealisnests on the island of Selvagem Grande in the north-eastern Atlantic. In 2002, a programme of eradication was conducted to remove two alien invasive mammals, the house mouseMus musculusand European rabbitOryctolagus cuniculus. Preliminary studies recorded beneficial effects of the eradications for a variety of plant and animal species, including Cory's shearwater. We recorded fledging rates of shearwaters for 1982–2001, prior to the eradication, and for 2002–2020, after the eradication, from two quadrats, each containing 134–329 nest sites. Although there was annual fluctuation in fledging rates in the quadrats, the mean rate of 40.74 ±SD 3.92 fledglings per 100 nest sites for the two quadrats combined prior to the eradication of mammals increased significantly, to 52.88 ± SD 5.03 per 100 nest sites, after the eradications. Because the two mammals were removed synchronously it is difficult to know which factors depressed fledging of Cory's shearwaters on Selvagem Grande. However, the predatory behaviour of house mice on other oceanic islands, and the fact that increased fledging was seen soon after the eradications occurred, suggest predation by house mice on shearwater hatchlings was the main cause of losses.
A new species ofEchinostoma(Trematoda: Echinostomatidae) from the ‘revolutum’ group found in Brazil: refuting the occurrence ofEchinostoma miyagawai(=E. robustum) in the Americas

Published: October 2021

AbstractAlthoughEchinostoma robustum(currently a synonym ofE. miyagawai) was reported in the Americas based on molecular data, morphological support on adult parasites is still required. Herein, a new species ofEchinostomais described based on worms found in a chicken from Brazil. Molecular phylogenetic analyses based on 28S (1063 bp), ITS (947 bp) and Nad-1 (442 bp) datasets reveal the inclusion of the new species withinEchinostoma‘revolutum’ species complex. Moreover, it was verified the conspecificity between cercariae previously identified asE. robustumin Brazil [identical ITS and only 0.3% of divergence (1 nucleotide) in Nad-1]. Species discovery analyses show that these two isolates form an independent lineage (species) amongEchinostomaspp. Compared toE. miyagawai, the new species presents relatively high divergence in Nad-1 (7.88–9.09%). Morphologically, the specimens are distinguished from all nominal species from the ‘revolutum’ species complex by the more posterior position of the testes (length of post-testicular field as a proportion of body length about 20%). They further differ fromE. miyagawaiand South AmericanEchinostomaspp. by the higher proportion of forebody to the body length. Therefore, combined molecular and morphological evidence supports the proposal of the species named here asEchinostoma pseudorobustumsp. nov.
Design of sensing system for experimental modeling of soft actuator applied for finger rehabilitation
Authors: Davarzani Shokoufeh , Ahmadi-Pajouh Mohammad Ali , Ghafarirad Hamed 
Published: October 2021

AbstractSafe interaction and inherent compliance with soft robots have motivated the evolution of soft rehabilitation robots. Among these, soft robotic gloves are known as an effective tool for stroke rehabilitation. This research proposed a pneumatically actuated soft robotic for index finger rehabilitation. The proposed system consists of a soft bending actuator and a sensing system equipped with four inertial measurement unit sensors to generate kinematic data of the index finger. The designed sensing system can estimate the range of motion (ROM) of the finger’s joints by combining angular velocity and acceleration values with the standard Kalman filter. The sensing system is evaluated regarding repeatability and reliability through static and dynamic experiments in the first step. The root mean square error attained in static and dynamic states are 2$^\circ$and 3$^\circ$, sequentially, representing an efficient function of the fusion algorithm. In the next step, experimental models have been developed to analyze and predict a soft actuator’s behavior in free and constrained states using the sensing system’s data. Thus, parametric system identification methods, artificial neural network—multilayer perceptron (ANN-MLP), and artificial neural network—radial basis function algorithms (ANN-RBF) have been compared to achieve an optimal model. The results reveal that ANN models, particularly RBF ones, can predict the actuator behavior with reasonable accuracy in the free and constrained state (<1$^\circ$). Hence, the need for intricate analytical modeling and material characterization will be eliminated, and controlling the soft actuator will be more practical. Besides, it assesses the ROM and finger functionality.
Calcium carbonate saturation states along the West Antarctic Peninsula
Authors: Jones Elizabeth M. , Hoppema Mario , Bakker Karel , de Baar Hein J.W. 
Published: October 2021

AbstractThe waters along the West Antarctic Peninsula (WAP) have experienced warming and increased freshwater inputs from melting sea ice and glaciers in recent decades. Challenges exist in understanding the consequences of these changes on the inorganic carbon system in this ecologically important and highly productive ecosystem. Distributions of dissolved inorganic carbon (CT), total alkalinity (AT) and nutrients revealed key physical, biological and biogeochemical controls of the calcium carbonate saturation state (Ωaragonite) in different water masses across the WAP shelf during the summer. Biological production in spring and summer dominated changes in surface water Ωaragonite (ΔΩaragonite up to +1.39; ~90%) relative to underlying Winter Water. Sea-ice and glacial meltwater constituted a minor source of AT that increased surface water Ωaragonite (ΔΩaragonite up to +0.07; ~13%). Remineralization of organic matter and an influx of carbon-rich brines led to cross-shelf decreases in Ωaragonite in Winter Water and Circumpolar Deep Water. A strong biological carbon pump over the shelf created Ωaragonite oversaturation in surface waters and suppression of Ωaragonite in subsurface waters. Undersaturation of aragonite occurred at < ~1000 m. Ongoing changes along the WAP will impact the biologically driven and meltwater-driven processes that influence the vulnerability of shelf waters to calcium carbonate undersaturation in the future.
Quadricuspid aortic valve and a large patent ductus arteriosus treated with device closure
Authors: Sultan Mehboob , Awan Khush Bakht , Khan Asad 
Published: October 2021

AbstractQuadricuspid aortic valve is a remarkably rare congenital cardiac anomaly that predominantly becomes regurgitant with the passage of time. Aortic valve stenosis and aortic root dilatation are less common in quadricuspid aortic valve as compared to bicuspid aortic valve. The clinical presentation depends upon the functional status of the aortic valve, left ventricular function, and associated cardiac or coronary anomalies. The quadricuspid aortic valve is easily visualised during transthoracic echocardiogram with a characteristic X pattern of aortic valve in diastole. The association of quadricuspid aortic valve with patent ductus arteriosus is exceedingly rare. We are reporting a case of young girl with mildly regurgitant quadricuspid aortic valve, large patent ductus arteriosus, and volume-loaded left heart who underwent a successful device closure of her patent ductus arteriosus. To the best of our knowledge, such a case is being reported from Pakistan for the first time.
Are interventions delivered by healthcare professionals effective for weight management? A systematic review of systematic reviews
Authors: Epton Tracy , Keyworth Christopher , Goldthorpe Joanna , Calam Rachel , Armitage Christopher J 
Published: October 2021

AbstractObjective:There are many systematic reviews of weight management interventions delivered by healthcare professionals (HCP), but it is not clear under what circumstances interventions are effective due to differences in review methodology. This review of systematic reviews synthesises the evidence about: (a) the effectiveness of HCP-delivered weight management interventions and (b) intervention and sample characteristics related to their effectiveness.Design:The review of reviews involved searching six databases (inception – October 2020). Reviews were included if they were (a) systematic, (b) weight management interventions delivered, at least partially, by HCP, (c) of randomised controlled trials and (d) written in English. Data regarding weight management outcomes (e.g. weight) and moderating factors were extracted. Secondary analyses were conducted using study-level data reported in each of the reviews.Setting:The review included studies that were delivered by HCP in any clinical or non-clinical setting.Participants:Not applicable.Results:Six systematic reviews were included (forty-six unique studies). First-level synthesis showed that weight management interventions delivered by HCP are effective. The second-level synthesis found that interventions are only successful for up to 6 months, are most effective for women, non-Caucasians and adults and are most effective if they have at least six sessions.Conclusions:As interventions are only successful for up to 6 months, they are not sufficient for achieving and maintaining a healthy weight.
