Colloidal exchange flow in ducts
Authors: Alba K. 
Published: May 2022

Buoyancy-driven exchange flow, i.e. drainage of a heavy colloidal suspension by an immiscible light pure fluid in a vertical duct, is studied analytically. A lubrication model is developed for two-dimensional channel and axisymmetric pipe geometries. The outcome transport equations are solved numerically to capture the effect of important governing dimensionless parameters: Péclet number, precursor film thickness, Reynolds number, mixtures’ viscosity ratio, initial volume fraction of hard-sphere particles, particles concentration within the precursor film, and capillary number. Recent study of colloidal film flow over a flat surface reveals interface thinning over time due to diffusion impact on suspension viscosity. However, the current model suggests that there is no such thinning phenomenon observed for colloidal flows within confined geometry unless in the absence of surface tension. The extent of the mixed particle zone along the duct grows as the Péclet number is decreased. Precursor film thickness is found to decrease the capillary ridge height forming at heavy suspension front. Either an increase in the Reynolds number or a decrease in light-to-heavy-fluid viscosity ratio extends the interpenetration rate of mixtures. As the bulk volume fraction of particles is increased close to 50 %, interesting secondary fronts emerge within the flow that coincide with the range where the diffusion coefficient is minimized. The heavy suspension layer drains slightly faster when the gradient in particle concentration between the bulk and precursor film regions is maximum. Finally, the non-monotonic impact of surface tension on the extent of mixtures’ exchange zone is uncovered via simulations conducted at various capillary numbers.
Effect of relational capability on dynamic capability: exploring the role of competitive intensity and environmental uncertainty
Authors: Singh Ritu , Charan Parikshit , Chattopadhyay Manojit 
Published: May 2022

AbstractThis study empirically examines the role of market dynamism and a firm's relational capability in the development of dynamic capability. A moderated hierarchical regression method has been used on the survey data of 218 Indian firms to test the objectives of the study. The findings suggest that relational capability (namely, customer linking capability and strategic partnering capability) is an important driver of dynamic capability. However, the effectiveness of relational capability is dependent on the market dynamism; particularly, when competition intensifies, the impact of customer linking capability declines, whereas the impact of strategic partnering capability on dynamic capability becomes stronger. Furthermore, the finding suggests that even though environmental uncertainty represents an important element of market dynamism, it is a driver, rather than a moderator, of dynamic capability. The study contributes to the extant literature by explicitly specifying the relational capability as a specific competence to develop dynamic capability under different market conditions.
The Importance of the Promotion of Evidence-Based Practice as a Reasonable Adjustment in Mainstream Education Settings for Students With Autism Spectrum Disorder
Authors: Garrad Traci-Ann , Vlcek Samantha , Page Angela 
Published: May 2022

AbstractAutism spectrum disorder (ASD) is a neurodevelopmental condition that can affect a person’s ability to manage the complexities of varied social and environmental situations. This is particularly evident in the dynamic context of a school classroom. To assist students with ASD to navigate the complexities of Australian primary and secondary mainstream classrooms, educators are required to provide ‘reasonable adjustments’ to support learning; that is, to make changes that are practicable and achievable in order for students to access learning on the same basis as their peers. We present an argument that the ‘reasonable adjustments’ made by schools to ensure that students with ASD have equitable learning opportunities should meet a criterion of acceptability where the adjustment is evidence based. The paper also offers a summary of evidence-based pedagogical strategies that have been effective for students with ASD and concludes with a discussion offering evidence-based practices as a solution to meeting legislative requirements for students with disability.
Unraveling the force dynamics in conceptual metaphors of COVID-19: a multilevel analysis
Authors: Kazemian Reza , Rezaei Hadaegh , Hatamzadeh Somayeh 
Published: May 2022

AbstractSo far, cognitive linguistics studies on COVID-19 have focused mainly on conceptual metaphors, paying scant attention to other construal operations such as force dynamics (FD). Adopting Kövecses’s (2020, Rivista Italiana di Filosofia del Linguaggio) hybrid account of conceptual metaphor and FD, this study attempts to outline an enriched cognitive view of the figurative conceptualization of illness. It also aims to answer the question: Can FD and conceptual metaphors be merged in illness metaphors, particularly corona-related ones? Research in cognitive linguistics has focused on certain source domains, such as war, fire, natural force, and wild animal, through which COVID-19 is conceptualized metaphorically. Since these metaphors feature the exchange of forces and actions, a more detailed account of these two construals could be fruitful, especially the potential force schema which underlies the detected source domains. Using an amalgamated model of conceptual metaphor theory and FD, significant associations were identified between two force-exerting elements, namely Agonist and Antagonist. These findings raise important theoretical issues that have a bearing on clarifying the correlation between illness metaphors and Talmy’s force-dynamic theory to cast some light on the complex metaphorical expressions embracing the subject under scrutiny.
Protests in Postwar Societies: Grievances and Contentious Collective Action in Kosovo
Authors: Kelmendi Pëllumb , Skendaj Elton 
Published: May 2022

AbstractMost research on protests has been conducted in peaceful societies, whereas we know far less about contentious collective action in postwar contexts. To fill this gap, we offer a theory that perceived ethnic grievances related to group security and group status are particularly likely to generate protest mobilization in postwar societies. To test this theory and alternative hypotheses, we investigate trends in protest behavior in postwar Kosovo using an original protest event dataset and existing survey data. We find that protest behavior in postwar Kosovo is significantly shaped by perceived ethnic grievances: the majority of protest grievances center around group security and group status concerns. Protests about economic justice or good governance demands are significantly rarer. Using data from existing surveys, we also investigate the determinants of variation in individual protest participation. Our analysis reveals that perceived ethnic discrimination is strongly associated with individual protest participation in Kosovo.

ABSTRACTThe Pleistocene history of the leopard (Panthera pardus) in Europe has been documented by the material obtained from 312 localities, with the last dated ∼1.1 Myr. The relatively small and gracile form of the leopard was very rare during the late Early and Middle Pleistocene. Only after the disappearance of the jaguar (Panthera gombaszoegensis) did P. pardus spread widely in Europe, increasing in size and ecologically substituting P. gombaszoegensis. The number of late Middle Pleistocene localities with leopard remains, younger than 300 kyr, increased considerably. The leopard reached the maximum extension of its geographical range in the Late Pleistocene. The Iberian Peninsula was the last European refuge for this cat. Six sites, the Naciekowa, Obok Wschodniej, Radochowska, and Wschodnia Caves from the Sudety Mountains and the Biśnik and Dziadowa Skała Caves from the Kraków-Częstochowa Upland, have documented the presence of the leopard in Poland between MIS 10/9 and MIS 3. These records are from rocky regions with rugged terrain and are located in the territory of Silesia (southern Poland). A newly obtained radiocarbon date (43–42 kyr) from the Radochowska Cave directly confirms the occurrence of P. pardus in the Sudety Mountains in the middle part of MIS 3.
Uneasy Neighbors: The Making of Sectarian Difference and Alevi Precarity in Urban Turkey
Authors: Gökarıksel Banu , Secor Anna J. 
Published: May 2022

AbstractThis study takes a critical perspective on the making of sectarian difference and Alevi precarity in contemporary Turkey. Drawing on our research from 2013 to 2016, we present an analysis of stories and conversations that took place amongst Alevi and Sunni focus group participants, primarily in Istanbul. These conversations illustrate how sectarian difference can be made in the relations between neighbors as differences become coded as sectarian and taken up within systems of power and domination. At the same time, our research also shows how, in the entangled relations between neighbors, questions of ethics and mutual responsibility arise, though these relations sometimes become uneasy or even unbearable. Finally, we show how the question of “knowing” difference is taken up within a power-laden discourse of sectarianism, one that is tied to the history of Alevis (and others) in Turkey while also extending well beyond this context.
Contrasting temperature responses in seasonal timing of cercariae shedding by Rhipidocotyle trematodes

Published: May 2022

AbstractGlobal warming is likely to lengthen the seasonal duration of larval release by parasites. We exposed freshwater mussel hosts, Anodonta anatina, from 2 high-latitude populations to high, intermediate and low temperatures throughout the annual cercarial shedding period of the sympatric trematodes Rhipidocotyle fennica and R. campanula, sharing the same transmission pathway. At the individual host level, under warmer conditions, the timing of the cercarial release in both parasite species shifted towards seasonally earlier period while its duration did not change. At the host population level, evidence for the lengthening of larvae shedding period with warming was found for R. fennica. R. campanula started the cercarial release seasonally clearly earlier, and at a lower temperature, than R. fennica. Furthermore, the proportion of mussels shedding cercariae increased, while day-degrees required to start the cercariae shedding decreased in high-temperature treatment in R. fennica. In R. campanula these effects were not found, suggesting that warming can benefit more R. fennica. These results do not completely support the view that climate warming would invariably increase the seasonal duration of larval shedding by parasites, but emphasizes species-specific differences in temperature-dependence and in seasonality of cercarial release.

AbstractHow parasites alter host feeding ecology remains elusive in natural populations. A powerful approach to investigate the link between infection and feeding ecology is quantifying unique and shared responses to parasite infection in related host species within a common environment. Here, 9 pairs of sympatric populations of the three-spined and nine-spined stickleback fishes were sampled across a range of freshwater and brackish habitats to investigate how parasites alter host feeding ecology: (i) biotic and abiotic determinants of parasite community composition, and (ii) to what extent parasite infection correlates with trophic niche specialization of the 2 species, using stable isotope analyses (δ15N and δ13C). It was determined that parasite community composition and host parasite load varied among sites and species and were correlated with dissolved oxygen. It was also observed that the digenean Cyathocotyle sp.'s abundance, a common directly infecting parasite with a complex life cycle, correlated with host δ13C in a fish species-specific manner. In 6 sites, correlations were found between parasite abundance and their hosts' feeding ecology. These effects were location-specific and occasionally host species or host size-specific. Overall, the results suggest a relationship between parasite infection and host trophic niche which may be an important and largely overlooked ecological factor. The population specificity and variation in parasite communities also suggest this effect is multifarious and context-dependent.

AbstractDibothriocephalus latus is the most frequent causative agent of fish-borne zoonosis (diphyllobothriosis) in Europe, where it is currently circulating mainly in the Alpine lakes region (ALR) and Russia. Three mitochondrial genes (cox1, cob and nad3) and 6 microsatellite loci were analysed to determine how is the recently detected triploidy/parthenogenesis in tapeworms from ALR displayed at the DNA level. A geographically distant population from the Krasnoyarsk Reservoir in Russia (RU-KR) was analysed as a comparative population. One or 2 alleles of each microsatellite locus was detected in plerocercoids from RU-KR, corresponding to the microsatellite pattern of a diploid organism. In contrast, 1–3 alleles were observed in tapeworms from ALR, in accordance with their triploidy. The high diversity of mitochondrial haplotypes in D. latus from RU-KR implied an original and relatively stable population, but the identical structure of mitochondrial genes of tapeworms from ALR was probably a consequence of a bottleneck typical of introduced populations. These results indicated that the diploid/sexually reproducing population from RU-KR was ancestral, located within the centre of the distribution of the species, and the triploid/parthenogenetically reproducing subalpine population was at the margin of the distribution. The current study revealed the allelic structure of the microsatellite loci in the triploid tapeworm for the first time.

AbstractWild birds are hosts of Culicoides from as early on as the nesting stage when constrained to their nests. However, the environmental factors which determine the abundance and composition of Culicoides species within each bird nest are still understudied. We sampled Culicoides from Eurasian blue tit (Cyanistes caeruleus) nests found in 2 types of forests located in southern Spain. Firstly, we monitored the abundance of Culicoides species in bird nests from a dry Pyrenean oak deciduous forest and a humid mixed forest comprising Pyrenean and Holm oaks throughout 2 consecutive years. During the 3rd year, we performed a cross-fostering experiment between synchronous nests to differentiate the role of rearing environment conditions from that of the genetically determined or maternally transmitted cues released by nestlings from each forest. We found 147 female Culicoides from 5 different species in the birds' nests. The abundance of Culicoides was higher in the dry forest than in the humid forest. Culicoides abundance, species richness and prevalence were greater when the nestlings were hatched later in the season. The same pattern was observed in the cross-fostering experiment, but we did not find evidence that nestling's features determined by the forest of origin had any effect on the Culicoides collected. These results support the notion that habitat type has a strong influence on the Culicoides affecting birds in their nests, while some life history traits of birds, such as the timing of reproduction, also influence Culicoides abundance and species composition.

Abstract

Objectives
To clarify the concept of disruptive technologies in health care, provide examples and consider implications of potentially disruptive technologies for health technology assessment (HTA).

Methods
We conducted a systematic review of conceptual and empirical papers on healthcare technologies that are described as “disruptive.” We searched MEDLINE and Embase from 2013 to April 2019 (updated in December 2021). Data extraction was done in duplicate by pairs of reviewers utilizing a data extraction form. A qualitative data analysis was undertaken based on an analytic framework for analysis of the concept and examples. Key arguments and a number of potential predictors of disruptive technologies were derived and implications for HTA organizations were discussed.

Results
Of 4,107 records, 28 were included in the review. Most of the papers included conceptual discussions and business models for disruptive technologies; only few papers presented empirical evidence. The majority of the evidence is related to the US healthcare system. Key arguments for describing a technology as disruptive include improvement of outcomes for patients, improved access to health care, reduction of costs and better affordability, shift in responsibilities between providers, and change in the organization of health care. A number of possible predictors for disruption were identified to distinguish these from “sustaining” innovations.

Conclusions
Since truly disruptive technologies could radically change technology uptake and may modify provision of care patterns or treatment paths, they require a thorough evaluation of the consequences of using these technologies, including economic and organizational impact assessment and careful monitoring.
The epsilon-knowledge: an emerging complement of Machlup's types of disciplinary knowledge
Authors: Horváth Imre 
Published: May 2022

Abstract
Machlup used the words alpha, beta, and gamma to identify humanities, science, and social science as three distinct fields of academic learning and knowing, in addition to general knowledge. Gilles and Paquet identified a fourth type of disciplinary knowledge and labeled it as delta. This includes the knowledge of creative disciplines such as design, law, and economy. Since the time of these road-paving works, a lot has changed. In the last two decades, various concepts and manifestations of intellectualized engineered systems have appeared. A paradigmatic feature of these systems, exemplified by smart cyber-physical systems, is that they collect, infer, or extract massive amount of synthetic system knowledge (M-SSK) based on some pre-programmed human knowledge. The amount of this type of knowledge grows continuously. It can be aggregated on system level and on system of systems level. This paper argues that this aggregated M-SSK is not covered by the abovementioned four genres of knowledge. In fact, it represents a new genre. The conducted literature study underpins this claim. Therefore, the paper suggests dealing with it as a new genre, called epsilon-knowledge. Artificial intelligence, system engineering, cyber-physical systems, and knowledge engineering are the disciplines dealing with epsilon-knowledge. The paper refers to sympérasmology as the proper conceptual framework of studying this genre of knowledge.
The influence of language shift on Sanapaná vowels: An exemplar-based perspective
Authors: Van Gysel Jens E. L. 
Published: May 2022

AbstractThis paper presents the first sociophonetic study of Sanapaná (Enlhet-Enenlhet), spoken by around one thousand people in Paraguay. It examines the effects of L2 (Spanish/Guaraní) fluency and loss of L1 exposure on vowel quality and within-category variability of /e, o/ productions in the Sanapaná /e, a, o/ system. Data from eleven native Sanapaná speakers suggest that age and multilingualism may have little explanatory power by themselves. Speakers living in a majority-L2 environment show greater within-category variability and increased convergence of /e, o/ toward the L2 high vowels /i, u/ than daily users of Sanapaná. This suggests that decreased L1 exposure is the main factor driving language shift-related change in Sanapaná. I explain these findings in an exemplar-theoretic framework. Although the number of speakers sampled is limited, these data provide a valuable addition to our knowledge of sociolinguistic variation in small, underrepresented communities.
Chronic, increasing, and decreasing peer victimization trajectories and the development of externalizing and internalizing problems in middle childhood

AbstractChildren’s peer victimization trajectories and their longitudinal associations with externalizing and internalizing problems were investigated from Grades 2 to 5. Secondary data analysis was performed with the Early Childhood Longitudinal Study (ECLS-K-2011; n = 13,860, Mage = 8.1 years old in the spring of Grade 2; 51.1% male, 46.7% White, 13.2% African-American, 25.3% Hispanic or Latino, 8.5% Asian, and 6.1% other or biracial). Children who experienced high and persistent levels of peer victimization (high-chronic victims) exhibited co-occurring externalizing and internalizing problems. Moreover, among high-chronic victims, boys had a more pronounced increase in their externalizing trajectories, and girls had greater increases in their social anxiety trajectories. In contrast, those with decreasing peer victimization across time exhibited signs of recovery, particularly with respect to their social anxiety. These findings elucidated how chronic, increasing, and decreasing victims exhibited distinct patterns in the co-occurring development of their externalizing and internalizing problems, and how findings varied depending on the form of problem behavior and by child sex.
Twitter as Higher-Education Community of Practice: A Political Science Perspective
Authors: Jester Natalie 
Published: May 2022

ABSTRACTA community of practice is where a group works together toward a shared goal. This article argues that Twitter hosts a community of practice within political science and international relations. This occurs in three key ways: (1) offering an area to share feelings about our role as educators, (2) connecting to a wider network of educators in our discipline (and other disciplines), and (3) providing a space to proffer practical support. This has been especially true during the current COVID-19 pandemic, when many educators are teaching remotely and potentially feeling cut off from colleagues and students at their institution. In more normal times, Twitter also offers a valuable means of connecting with other scholars in the discipline across the world, providing a space to learn from and support one another. The article concludes by reflecting on what this might mean for continued professional development in the political science and international relations discipline.
