Conceptualization of research themes and directions in business ecosystem strategies: a systematic literature review
Authors: Krome Maximilian Julius , Pidun Ulrich 
Published: December 2022

AbstractMotivated by the rapid advancements in the field of business ecosystems (BEs), this paper presents a holistic overview of existing research in the field of business ecosystem strategy. As scholars have noted, BE strategy poses new challenges and diverges from traditional thinking in multiple ways. Researchers have investigated parts of strategy in that regard; however, a holistic approach to BE strategy does not exist. To this end, this study relies on a systematic literature review approach and analyzes contributions from across disciplines in an attempt to derive a holistic ecosystem strategy framework. The study identifies six main elements that reflect strategic considerations along subsequent stages of decision-making. It then discusses the fifteen sub-streams identified in the literature, placing them in their strategic context. Based on this analysis, gaps in the literature and future research opportunities are identified. This study is motivated by the aspiration to make the topic of ecosystem strategies more accessible for scholars and practitioners, while enabling a broader discussion based on the current state of research.
Riemann–Roch for stacky matrix factorizations
Authors: Choa Dongwook , Kim Bumsig , Sreedhar Bhamidi 
Published: December 2022

AbstractWe establish a Hirzebruch–Riemann–Roch-type theorem and a Grothendieck–Riemann–Roch-type theorem for matrix factorizations on quotient Deligne–Mumford stacks. For this, we first construct a Hochschild–Kostant–Rosenberg-type isomorphism explicit enough to yield a categorical Chern character formula. Then, we find an expression of the canonical pairing of Shklyarov under the isomorphism.
Stratigraphy and chronology of the Cala Mosca site, SW Sardinia (Italy)
Authors: Sechi Daniele , Andreucci Stefano , Cocco Fabrizio , Pascucci Vincenzo 
Published: December 2022

AbstractThe relict beach deposit of the Cala Mosca marine terrace is considered an important section of Marine Isotopic Stage (MIS) 5e (ca. 125 ka) sea-level highstands. Analysis of the stratigraphy and sediments of the deposit indicates the presence of a composite marine terrace comprising two superimposed marine units, luminescence dated to the MIS 5e (137 ± 7, 134 ± 7 ka) and MIS 5c (92 ± 6 ka) substages. The stratigraphic superimposition of the two highstands, both placed ~5 m above present sea level, agrees with other areas along the Sardinia coasts. The evident superimposition of two sea-level highstands and development of the composite terrace cannot be accounted solely by high-frequency sea-level oscillation that occurred within MIS 5 for the Mediterranean Sea. This suggests controversial, but significant, regional versus local tectonic activity occurred during the Late Pleistocene.
The Logic of Paul's Address in 2 Corinthians 10-13
Authors: Engberg-Pedersen Troels 
Published: December 2022

Abstract2 Cor 10–13 may be seen to hang together closely, both internally and with the rest of the canonical letter, once one notices the very careful manner in which Paul distinguishes between and handles three groups: (i) the Corinthians as such, a group that includes his ‘own people’ and sometimes also (ii) his internal critics; and (iii) the rival missionaries. The four chapters are built over a set of four motifs: 2nd or 3rd person? absence or presence? meekness or boldness? building up or tearing down? In light of this, one finds the following structure: A (10.1–11) on the i- and ii-groups; B (10.12–11.21), C (11.22–12.10), and D (12.11–13) on the iii- and i-groups; and E (12.14-13.13) on the i- and ii-groups. The four chapters – and indeed, the letter as a whole – have an inner dynamic that reaches its writerly goal in the comparison of Paul to the iii-group (C). The final, rhetorical aim, however, consists in establishing the proper relationship between Paul himself and the i-group as he is about to reach Corinth once more in the flesh.
Unfinished Business: The Ending of Mark in Two Catena Manuscripts
Authors: Houghton H.A.G. 
Published: December 2022

AbstractTwo Greek gospel manuscripts with an exegetical commentary in catena form present a text of Mark which ends in the middle of Mark 16.8. One is GA 304, a twelfth-century codex which is often adduced as a witness to the Short Ending. The other is the eleventh-century GA 239, which has not previously featured in discussions of the conclusion of Mark. In each case, it is shown that considerations of scribal practice, codicology and the broader traditions of text and catena mean that neither witness should be treated as evidence for the Short Ending as found in Codices Sinaiticus and Vaticanus.

Published: December 2022

AbstractHaemosporidian generaPlasmodium,HaemoproteusandLeucocytozoon, responsible for avian malarial infections, are highly diverse and have a wide range of health effects and predictors, depending on the host and its environmental context. Here, we present, for the first time, detailed information on the identity, prevalence and parasitaemia of haemosporidians and other haemoparasites that infect the ash-breasted Sierra finch,Geospizopsis plebejus, in an Andean dry forest. We study the consequences of infection in the host body and health conditions and explore the environmental and intrinsic factors that influence infection status and parasitaemia. We conducted diagnoses by cytochrome b (cytb) sequencing and morphological identification, and estimated the levels of parasitaemia based on microscopy. We identified 6cytblineages infectingG. plebejus. Two of them were new lineages:Haemoproteussp. GEPLE01 and GEPLE02. We also detectedHaemoproteussp. ZOCAP08,Haemoproteussp. AMAVIR01,Plasmodium homopolareBAEBIC02 andPlasmodium cathemeriumZONCAP15. By microscopy, we detectedHaemoproteus coatneyi,Haemoproteus erythrogravidus,P. homopolareand other unidentified species ofHaemoproteus,Plasmodium,Babesiasp. and 1 microfilaria. We found no evidence ofLeucocytozoon. Additionally, we detected several coinfections by sequencing and microscopy. The prevalence of haemosporidian infections was high (87.7%), and the mean parasitaemia was 61.65 infected cells per 10 000 erythrocytes examined. Prevalence and parasitaemia were higher forHaemoproteusthan forPlasmodium.Haemoproteussp. AMAVIR01 showed the highest prevalence (43.1%) and mean parasitaemia (94.39/10 000 erythrocytes) and might be associated withH. coatneyi. Immature individuals showed a lower prevalence than adults, supporting previous findings.
Evidence for two stages of prediction in non-native speakers: A visual-world eye-tracking study
Authors: Corps Ruth E. , Liao Meijian , Pickering Martin J. 
Published: December 2022

AbstractComprehenders predict what a speaker is likely to say when listening to non-native (L2) and native (L1) utterances. But what are the characteristics of L2 prediction, and how does it relate to L1 prediction? We addressed this question in a visual-world eye-tracking experiment, which tested when L2 English comprehenders integrated perspective into their predictions. Male and female participants listened to male and female speakers producing sentences (e.g.,I would like to wear the nice…) about stereotypically masculine (target: tie; distractor: drill) and feminine (target: dress; distractor: hairdryer) objects. Participants predicted associatively, fixating objects semantically associated with critical verbs (here, the tie and the dress). They also predicted stereotypically consistent objects (e.g., the tie rather than the dress, given the male speaker). Consistent predictions were made later than associative predictions, and were delayed for L2 speakers relative to L1 speakers. These findings suggest prediction involves both automatic and non-automatic stages.

AbstractObjective:To examine energy drink consumption among adolescents in the UK and associations with deprivation and dietary inequalities.Design:Quantitative dietary and demographic data from the National Diet and Nutrition Survey (NDNS) repeated cross-sectional survey were analysed using logistic regression models. Qualitative data from semi-structured interviews were analysed using inductive thematic analysis.Setting:UK.Participants:Quantitative data: nationally representative sample of 2587 adolescents aged 11–18 years. Qualitative data: 20 parents, 9 teachers and 28 adolescents from Hampshire, UK.Results:NDNS data showed adolescents’ consumption of energy drinks was associated with poorer dietary quality (OR 0·46 persd; 95 % CI (0·37, 0·58);P< 0·001). Adolescents from more deprived areas and lower income households were more likely to consume energy drinks than those in more affluent areas and households (OR 1·40; 95 % CI (1·16, 1·69);P< 0·001; OR 0·98 per £1000; 95 % CI (0·96, 0·99);P< 0·001, respectively). Between 2008 and 2016, energy drink consumption among adolescents living in the most deprived areas increased, but decreased among those living in the most affluent neighbourhoods (P= 0·04). Qualitative data identified three themes. First, many adolescents drink energy drinks because of their friends and because the unbranded drinks are cheap. Second, energy drink consumption clusters with other unhealthy eating behaviours and adolescents do not know why energy drinks are unhealthy. Third, adolescents believe voluntary bans in retail outlets and schools do not work.Conclusions:This study supports the introduction of age-dependent legal restrictions on the sale of energy drinks which may help curb existing socio-economic disparities in adolescents’ energy drink intake.
Rapid Refreezing of a Marginal Ice Zone Across a Seafloor Distributed Acoustic Sensor
Authors: Baker Michael G. , Abbott Robert E. 
Published: December 2022

AbstractSeismic instruments such as broadband seismometers and distributed acoustic sensors (DAS) have a demonstrated potential for wide‐scale and continuous in situ monitoring of near‐surface environmental and anthropogenic processes. DAS is attractive for development as a multi‐geophysical observatory due to the prevalence of existing fiber infrastructure in regions with environmental, cultural, or strategic significance. Here we present results from a multi‐seasonal acquisition of DAS data on a seafloor cable in the Beaufort Sea, Alaska. During a November 2021 data collect we captured the rapid transition of ambient noise characteristics from an “ice‐free” state to an “ice‐bound” state. A sea ice formation front was plainly visible on the DAS record and was observed to propagate 20 km seaward over a period of 8 hr. Satellite‐based instrumentation were unable to record this event due to cloud cover, low light conditions, and orbital frequency.
Deccan Traps Volcanism Implicated in the Extinction of Non‐Avian Dinosaurs in Southeastern China

Published: December 2022

AbstractThe extinction of non‐avian dinosaurs and its cause(s) have been a matter of debate for several decades. Here we measured Hg and its isotopic composition, heavy metals, and magnetic parameter in a terrestrial basin in southeastern China. Hg exhibited anomalies from 66.4 to 65.6 Ma, with near‐zero to positive Δ199Hg values, which reflected the eruption of Deccan Traps (DT) magma. In addition, Hg anomalies coincided with the gradual extinction of non‐avian dinosaurs, thereby consistent with the hypothesis that DT played a key role in the mass extinction. Analysis of paleoclimatic records showed that both the Late Maastrichtian warming event (LMWE) and Dan‐C2 event occurred at the maxima of the 405‐kyr long eccentricity cycle, and the onset of the dinosaur decline was earlier than the LMWE, suggesting that the LMWE played an ancillary role in the mass extinction. The mechanism of how DT caused the mass extinction requires further investigation.

AbstractTo understand the main orographic and non‐orographic sources of gravity waves (GWs) over South America during an Experiment (Rapp et al., 2021, https://doi.org/10.1175/BAMS-D-20-0034.1), we propose the application of a rotational spectral analysis based on methods originally developed for oceanographic studies. This approach is deployed in a complex scenario of large‐amplitude GWs by applying it to reanalysis data. We divide the atmospheric region of interest into two height intervals. The simulations are compared with lidar measurements during one of the flights. From the degree of polarization and the total energy of the GWs, the contribution of the upward and downward wave packets is described as a function of their vertical wavenumbers. At low levels, a larger downward energy flux is observed in a few significant harmonics, suggesting inertial GWs radiated at polar night jet levels, and below, near to a cold front. In contrast, the upward GW energy flux, per unit area, is larger than the downward flux, as expected over mountainous areas. The main sub‐regions of upward GW energy flux are located above Patagonia, the Antarctic Peninsula and only some oceanic sectors. Above the sea, there are alternating sub‐regions dominated by linearly polarized GWs and sectors of downward GWs. At the upper levels, the total available GW energy per unit mass is higher than at the lower levels. Regions with different degrees of polarization are distributed in elongated bands. A satisfactory comparison is made with an analysis based on the phase difference between temperature and vertical wind disturbances.

AbstractChronic stress exposure induces maladaptive behavioral responses and increases susceptibility to neuropsychiatric conditions. However, specific neuronal populations and circuits that are highly sensitive to stress and trigger maladaptive behavioral responses remain to be identified. Here we investigate the patterns of spontaneous activity of proopiomelanocortin (POMC) neurons in the arcuate nucleus (ARC) of the hypothalamus following exposure to chronic unpredictable stress (CUS) for 10 days, a stress paradigm used to induce behavioral deficits such as anhedonia and behavioral despair [1, 2]. CUS exposure increased spontaneous firing of POMC neurons in both male and female mice, attributable to reduced GABA-mediated synaptic inhibition and increased intrinsic neuronal excitability. While acute activation of POMC neurons failed to induce behavioral changes in non-stressed mice of both sexes, subacute (3 days) and chronic (10 days) repeated activation of POMC neurons was sufficient to induce anhedonia and behavioral despair in males but not females under non-stress conditions. Acute activation of POMC neurons promoted susceptibility to subthreshold unpredictable stress in both male and female mice. Conversely, acute inhibition of POMC neurons was sufficient to reverse CUS-induced anhedonia and behavioral despair in both sexes. Collectively, these results indicate that chronic stress induces both synaptic and intrinsic plasticity of POMC neurons, leading to neuronal hyperactivity. Our findings suggest that POMC neuron dysfunction drives chronic stress-related behavioral deficits.
Improving weight loss RCTs. Measuring the step weight change from a sustained change in frequency of a particular eating or exercise pattern
Authors: Booth David A. , Laguna-Camacho Antonio 
Published: December 2022

AbstractThe public’s trust in the science of avoiding unhealthy weight depends on a radical reform of the design and execution of weight loss programmes and their clinical trials. This Perspective reiterates the longstanding argument for measuring the effectiveness of each component of an intervention on obesity. Body energy content change results from a difference in rates between input and output. These rates are determined by the frequencies of specific patterns of dietary behaviour, physical activity and thermal comfort, plus the cost of resting metabolism. Since fat-free mass changes alongside fat mass, the amount of change in weight from a change in the frequency of a behaviour pattern comes to an asymptote. That step change in weight per unit of behaviour change is measured by regression from the change in frequency of the behaviour that has been maintained from baseline to follow-up. For hard evidence, weight loss programme participants’ own words must be used to specify behaviour. In RCTs of multiple-component programmes, sequences of the behaviour patterns to be changed are randomised among groups. The resulting evidence on effective slimming practices can be delivered directly into therapeutic services and public health interventions for the culture investigated.
The evolutionary origin of avian facial bristles and the likely role of rictal bristles in feeding ecology
Authors: Delaunay Mariane G. , Brassey Charlotte , Larsen Carl , Lloyd Huw , Grant Robyn A. 
Published: December 2022

AbstractFacial bristles are one of the least described feather types and have not yet been systematically studied across phylogenetically diverse avian species. Consequently, little is known about their form, function and evolutionary history. Here we address this knowledge gap by characterising the evolution of facial bristles for the first time. We especially focus on rictal bristle presence and their associations with foraging behaviour, diet and habitat preferences in 1022 avian species, representing 91 families in 29 orders. Results reveal that upper rictal, lower rictal and interramal bristles were likely to be present in the most recent common ancestor of this avian phylogeny, whereas narial bristles were likely to be absent. Rictal bristle presence, length and shape varied both within and between avian orders, families and genera. Rictal bristles were gained or lost multiple times throughout evolution, which suggest that the different morphologies observed within species might not be homologous. Phylogenetic relatedness is also not likely to be the only driver of rictal bristle presence and morphology. Rictal bristle presence and length were associated with species-specific ecological traits, especially nocturnality. Our findings suggest that species foraging in low-light conditions are likely to have longer rictal bristles, and that rictal bristles are likely to have evolved in early birds.

AbstractTo gain a better understanding of the effects of biologics, we evaluated clinical outcomes in patients with moderate to severe exacerbations of ulcerative colitis (UC). This retrospective, multicenter study retrieved the entire clinical courses of UC patients who began treatments between 2004 and 2018. All exacerbations and clinical parameters, including treatment details for exacerbations and both remission and re-exacerbation dates, were identified during the observation period. Two different endpoints, the cumulative incidence rates of surgical resection and re-exacerbation, were evaluated separately in moderate to severe exacerbation events. Among 1401 patients, 1626 exacerbation events were determined according to a partial Mayo score (remission: < 2, mild: 2–4, moderate: 5–7, and severe: > 7). During the observation period, as administration rates of biologics increased, both surgical resection and hospitalization rates decreased, for 959 moderate to severe exacerbation events. We confirmed that biologics significantly reduced the cumulative re-exacerbation rate in moderate to severe exacerbation events during the study period compared with suboptimal therapies (a 0.507-fold decreased risk according to COX regression analysis, P < 0.001). However, they had not enough impact in reducing the cumulative incidence rate of surgical resection in moderate to severe exacerbation events that were corticosteroid-refractory or dependent (a 0.878-fold decreased risk according to COX regression analysis, P = 0.606). Biologics may improve remission duration, but these agents had no significant impact in reducing the risk of surgical resection in moderate to severe active UC.
Investigation of Vocal Bifurcations and Voice Patterns Induced by Asymmetry of Pathological Vocal Folds
Authors: Ikuma Takeshi , McWhorter Andrew J. , Adkins Lacey , Kunduk Melda 
Published: December 2022

Purpose:
Vocal fold asymmetry creates irregular entrainments and modulations in voice, which may lead to rough perceptual quality. The presence of asymmetry can also cause mid-phonation bifurcations where a small change in the phonatory system causes a drastic change in vibration pattern, resulting in transitions in and out of rough voice. This study surveys sustained phonation recordings of speakers with the diagnoses of vocal fold polyp or unilateral vocal fold paralysis to investigate the resulting voice patterns.

Method:
This retrospective study observed 71 sustained phonation recordings from 48 patients. Segments with distinctive signal patterns were identified within each recording with narrowband spectrogram and computer-assisted analysis of spectral peaks.

Results:

Phonation segmentation yielded 240 segments across all the recordings. Five voice patterns were recognized: (regularly or irregularly) entrained, modulated, uncoupled, unstable, and pulsed. Thirty-six patients (75%) exhibited irregular patterns. No single irregular pattern lasted for the entire phonation and was always accompanied by at least one mid-phonation bifurcation. Durations of the irregular segments (
M
= 0.4 s) were significantly shorter than the segments with the regular pattern (
M
= 1.4 s).

Conclusions:
The results suggest that vocal fold pathology frequently introduces dynamic vibratory patterns that affect both the acoustic signals and perceptions. Due to these abnormalities, it is important for clinical voice assessment protocols, both perceptual and acoustic, to account for these possible bifurcations, irregular signal patterns, and their tendencies.
