The Utility of Multistate Models: A Flexible Framework for Time-to-Event Data
Authors: Le-Rademacher Jennifer G. , Therneau Terry M. , Ou Fang-Shu 
Published: June 2022

AbstractPurpose of ReviewSurvival analyses are common and essential in medical research. Most readers are familiar with Kaplan–Meier curves and Cox models; however, very few are familiar with multistate models. Although multistate models were introduced in 1965, they only recently receive more attention in the medical research community. The current review introduces common terminologies and quantities that can be estimated from multistate models. Examples from published literature are used to illustrate the utility of multistate models.Recent FindingsA figure of states and transitions is a useful depiction of a multistate model. Clinically meaningful quantities that can be estimated from a multistate model include the probability in a state at a given time, the average time in a state, and the expected number of visits to a state; all of which describe the absolute risks of an event. Relative risk can also be estimated using multistate hazard models.SummaryMultistate models provide a more general and flexible framework that extends beyond the Kaplan-Meier estimator and Cox models. Multistate models allow simultaneous analyses of multiple disease pathways to provide insights into the natural history of complex diseases. We strongly encourage the use of multistate models when analyzing time-to-event data.

Published: June 2022

AbstractThis review assesses the leachate quality from waste disposal sites in tropical climate zone. Through this review, data from 228 leachate samples from 145 waste disposal sites from 18 countries in the tropical region were analyzed. The 12 types of sites were considered for the analysis based on the climatic conditions, age, and the operating condition of the site. Tropical rainforest, tropical monsoon, and tropical savanna climates were identified for the climatic zone classification. Age of site was classified as young and old. The operating conditions were classified as engineered landfill and open dump site. Eighteen leachate quality parameters were included in the analysis. Leachate pollution index indicated that young sites from tropical rainforest zone and tropical monsoon zone have higher pollution potential, while the pollution potential in tropical savanna zone did not demonstrate considerable difference in pollution potential in terms of age of the landfill. Considering the operating method of the sites, open dumpsites pose higher pollution potential. Positive correlation could be seen among biological oxygen demand, chemical oxygen demand, total dissolved solids, and total Kjeldahl nitrogen. pH negatively correlated with organic pollutants as well as heavy metals. Analysis of emerging contaminants present in landfill leachate is limited in tropical region; thus, it is recommended to conduct studies on emerging contaminants. Further, the leachate treatment options considered in tropical region are discussed in this review.
Gonadotropin Stimulation Reduces the Implantation and Live Birth Rate but Not the Miscarriage Rate of Embryos Transferred When Compared to Unstimulated In Vitro Fertilization

Published: June 2022

Abstract
Research suggests that gonadotropin stimulation in in vitro fertilization (IVF) treatment affects embryo quality and the endometrium that might influence embryo implantation, placentation and establishment of a viable pregnancy. We assessed the impact of gonadotropin stimulation on implantation, live birth and miscarriage rates per transferred embryo by comparing stimulated and unstimulated IVF treatment. In a cohort of 728 couples, 1310 IVF cycles with successful embryo transfer were analysed; 857 cycles were stimulated with gonadotropins > 75 IU/day (333 poor responder < 4 oocytes; 524 normal responders), and 453 were unstimulated. In total, 1913 fresh cleavage-stage embryos were transferred. Zygote but no embryo selection was performed, and supernumerous zygotes were vitrified. The implantation rate was defined as number of sonographically detected amniotic sacs; live birth rate as number of children born per transferred embryo. Modified mixed effect Poisson regression was used to account for the dependency of cycles and embryos within the same women and the same transfer cycle. Adjustments were made for maternal age, parity, primary or secondary infertility and indication for IVF. Per transferred embryo, implantation rates (rate ratio (RR) 1.37; 95% CI 1.04–1.81; p = 0.028; aRR 1.42; 95% CI 1.10–1.84; p = 0.008) and live birth rates (RR 1.33; 95% CI 0.95–1.86; p = 0.093; aRR 1.38; 95% CI 1.01–1.88; p = 0.044) were higher in NC-IVF compared to cIVF normal responders. Miscarriage did not differ (RR 0.99; 95% CI 0.59–1.65; p = 0.965; aRR 0.90; 95% CI 0.52–1.53 p = 0.698). Similar results were obtained in poor responders. The study suggests an impact of gonadotropin stimulation on the implantation potential of embryos.
The Impacts of Food Waste Information on Consumer Preferences for Blemished Produce and Implications for Food Retailers
Authors: Collart Alba J. , Interis Matthew G. , Henson Chloe’ , Maples Josh 
Published: June 2022

AbstractProduce that does not meet sellers’ esthetic standards may be redirected to alternative uses or wasted, but consumer trends indicate potential marketability of blemished produce. We conduct a nonhypothetical experimental auction to elicit consumer willingness-to-pay (WTP) for produce of varying degrees of blemish and test whether valuations are affected by (1) information on food waste resulting from grocery stores’ esthetic standards and (2) additional information on the environmental impacts of food waste. WTP for blemished produce increases as consumers become informed, but the information effects vary by blemishing degree. Market simulations indicate that introducing blemished produce can increase retailer revenue.
Cripping environmental education: rethinking disability, nature, and interdependent futures
Authors: Schmidt Jenne 
Published: June 2022

AbstractIn this article, I call for a cripping of environmental education as a necessary move in shifting away from the field’s current conceptions of disability as defect and deficiency, and towards disrupting the structures and processes that operate as normalizing technologies within ableism/sanism. Through an examination of the ways that the field of environmental education has/has not engaged critical disability politics, I illuminate how disability is not often included within environmental education literature. When it is, it is often through the use of disability as metaphor or through recommendations for best practices in accommodating disabilities. More often though within environmental education, disability has operated as a hidden curriculum, underpinning much of the field’s curricular, pedagogical, and even philosophical foundations. Through a cripping of the field these compulsory able-bodied/able-minded assumptions are made apparent. I suggest that by centering crip bodies and minds through cripistemologies, we might enable new ways of knowing, being in, connecting to, and understanding the natural world.
Some structural disanalogies between pronouns and tenses
Authors: Bjorkman Bronwyn M. 
Published: June 2022

AbstractA pronominal analysis of tense goes back to Partee (1973), motivated by a series of proposed parallels between the interpretation of tenses and that of pronouns. This article revisits Partee's interpretive parallels, as well as two more identified in Kratzer (1998), in light of subsequent developments in work on both temporal relations and on pronouns. The goal of this article is not to argue for or against a pronominal analysis of tense, but instead to make clearer the syntactic and semantic space within which such an analysis is situated, especially given that pronouns have been given increasingly complex syntactic representations even as tense has remained syntactically simplex.

Abstract

Objective:
Floods are one of Iran’s most important natural hazards, which cause a lot of damage every year. Various organizations, including non-governmental organizations (NGOs), participate in flood management. The present study aimed to explore the challenges and barriers of NGOs’ participation in the management of the flooding in Iran based on stakeholders’ experiences.

Methods:
This qualitative study is a case study that was conducted using the content analysis approach. Fifteen participants, including 3 national managers, 2 volunteers active in responding to recent floods, and 10 NGO managers/secretaries who had the knowledge or operational experience of participating in disaster management, were approached for interviews. Data were collected using a purposeful sampling method and continued until reaching data saturation.

Results:
Challenges and barriers to NGOs’ participation in flood management were categorized into 4 main categories and 14 subcategories, including policy-making challenges, managerial challenges, executive challenges, and socio-cultural challenges.

Conclusions:
As multiple NGOs take part in responding to disasters and performing relief operations, establishing a unified command and supervision system for effective coordination and collaborations among NGOs and other stakeholders is highly suggested. Further research is needed to develop a measurement tool for assessing the effectiveness of NGOs’ activities during disasters.
Buen Vivir under Correa: The Rhetoric of Participatory Democracy, the Reality of Rentier Populism
Authors: Posner Paul W. 
Published: June 2022

AbstractThis article seeks to understand the relationship between populism and participatory democracy through analysis of Rafael Correa’s left populist regime in Ecuador (2007–2017). It argues that rather than adhering to its own standard for participatory democracy, what the Correa regime referred to as the “Socialism ofBuen Vivir,” it employed the rhetoric of participatory democracy in the service of populist rule. As a result, the Correa regime failed to promote the participatory form of democracy and citizenship promised in Buen Vivir, its version of twenty-first-century socialism. Accordingly, analysis of the Correa regime demonstrates how the concentration of top-down executive power characteristic of populism in general, and rentier populism in particular, impedes the egalitarian and solidaristic mission of participatory democracy. Thus, inductive analysis of the Correa regime reinforces the conceptual understanding that populism is antagonistic and antithetical to participatory democracy.

AbstractA multiproxy oxygen and carbon isotope (δ13C and δ18O), growth rate, and trace element stalagmite paleoenvironmental record is presented for the Early Holocene from Ethiopia. The annually laminated stalagmite grew from 10.6 to 10.4 ka and from 9.7 to 9.0 ka with a short hiatus at ~9.25 ka. Statistically significant and coherent spectral frequencies in δ13C and δ18O are observed at 15–25 and 19–23 years, respectively. The observed ~1‰ amplitude variability in stalagmite δ18O is likely forced by nonequilibrium deposition, due to kinetic effects during the progressive degassing of CO2 from the water film during stalagmite formation. These frequencies are similar to the periodicity reported for other Holocene stalagmite records from Ethiopia, suggesting that multidecadal variability in stalagmite δ18O is typical. Several processes can lead to this multidecadal variability and operate in different directions. A hydroclimate forcing is likely the primary control on the extent of the partial evaporation of soil and shallow epikarst water and associated isotopic fractionation. The resulting oxygen isotope composition of percolation water is subsequently modulated by karst hydrology. Further isotopic fractionation is possible in-cave during nonequilibrium stalagmite deposition. Combined with possible recharge biases in drip-water δ18O, these processes can generate multidecadal δ18O variability.
Doctoral Mentorship Practices in Canadian Political Science
Authors: Berdahl Loleen , Malloy Jonathan , Young Lisa 
Published: June 2022

AbstractSupervisors shape the PhD student experience and play a critical role in students’ development. To what extent and in what ways are faculty engaged in mentorship? Are faculty mentoring more or differently now than in the past? This study of political science faculty from political science departments offering PhD programs in the English language finds that graduate supervision is changing over time, with mentorship practices becoming both more common and more varied. Supervisors do not appear to be simply replicating their own limited experience of mentorship as a PhD student. Instead, supervisors are becoming more actively and directly involved in their students’ research careers in ways that increase their students’ career opportunities. There is opportunity for institutions, at both the university and department level, to further invest in building the capacity and ability of supervisors to be effective mentors.
Physiological behaviour and nutritional status of coffee (Coffea arabica L. var. Castillo) trees in response to biochar application
Authors: Sanchez-Reinoso A. D. , Lombardini L. , Restrepo-Díaz H. 
Published: June 2022

AbstractApplying coffee pulp biochar (BC) can be a complementary practice to the application of chemical fertilizers (CF) of crops; however, little evidence of its combined effects on coffee cultivation has been reported. A field trial was carried out during two evaluation years (2019 and 2020) to analyse the effect of the application of different BC doses (0, 4, 8 and 16 t/ha) in combination with four levels of fertilization (0, 33, 66 and 100% of the nutritional requirements) on physiological responses of 3-year-old coffee (Coffea arabica L. var. Castillo) trees. The results indicated that trees with 0 t/ha BC and 0% CF showed the lowest values in all the physiological variables studied (gs = 269.9 and 126.8 mmol/m2/s; Chl = 61.7 and 54.7 At-leaf readings; yield = 0.21 and 0.22 kg of dry parchment coffee (DPC)/tree for 2019 and 2020, respectively). Coffee trees treated with 8 t/ha BC and CF levels of 100% registered the highest results in gs (424.9 and 366.9 mmol/m2/s), Chl (71.1 and 69.8 At-leaf readings), yield (0.41 and 0.57 kg of DPC/tree) in 2019 and 2020, respectively. In conclusion, the application of BC from coffee pulp, especially at a dose of 8 t/ha, generates a positive effect on yield, gs, leaf nutrient concentration and Chl of coffee trees. The use of BC can be an alternative to complement the mineral nutrition of commercial coffee crops to help reduce the application of CF.

AbstractThis experiment was conducted to evaluate the impact of substituting rice straw with citrus pulp (CRP), sweet potato peels (SPP) and vines (SPV) on fermentation quality and in vitro digestibility when ensiled with or without wet brewers' grains (WBG). Seven treatments were set as follows: (i) rice straw only (control); (ii) 800 g rice straw/kg + 200 g CRP/kg (RC); (iii) 720 g rice straw/kg + 180 g CRP/kg + 100 g WBG/kg (RC+); (iv) 800 g rice straw/kg + 200 g SPP/kg (RP); (v) 720 g rice straw + 180 g SPP/kg + 100 g WBG/kg (RP+); (vi) 800 g rice straw/kg + 200 g SPV/kg (RV); (vii) 720 g rice straw/kg + 180 g SPV/kg + 100 g WBG/kg (RV+). After ensiling for 3, 7, 14, 30 and 60 days, silos were opened for fermentation profile, aerobic stability and in vitro parameter analyses. All substitution types improved fermentation quality, characterized by significantly lower pH and NH3-N content, higher lactic acid content and V-scores. WBG application promoted hetero-fermentation and significantly increased DM losses, acetic acid and ethanol contents. After 60 days of ensiling, the NDF, ADF and cellulose contents in mixed silages significantly decreased compared to control. During aerobic exposure, WBG application significantly prolonged aerobic stability. SPV substitution significantly improved in vitro digestibility of dry matter, NDF and ADF. In conclusion, the SPP substitution combined with WBG application was recommended as a result of the optimal balance of fermentation quality, aerobic stability and in vitro digestibility.
Political Competition and Authoritarian Repression
Authors: Edwards Pearce 
Published: June 2022

abstractAuthoritarian regimes repress to prevent mass resistance to their rule. In doing so, regimes’ security forces require information about the dissidents who mobilize such resistance. Political competition, which fuels partisan rivalries, offers one solution to this problem by motivating civilians to provide needed information to security forces. Yet civilians share information about any political opponents, not just dissidents, which creates a challenge for regimes that want to target dissidents. Drawing on novel archival data from the immediate aftermath of the 1973 coup that brought Augusto Pinochet to power in Chile, a period that included civilian collaboration with repression, this article presents evidence that close pre-coup political competition is associated with more frequent repression and more targeting of non-dissidents. The author uses pre-coup democratic elections to measure political competition and addresses the challenge of estimating political preferences unaffected by repression. Qualitative evidence and further quantitative tests probe implications of the partisan rivalry mechanism and account for alternative explanations.
Entre mode et variation : une étude variationniste de l’emploi du subjonctif dans un parler du français acadien
Authors: Roussel Basile 
Published: June 2022

RésuméCet article s’intéresse à l’emploi du subjonctif en français acadien du nord-est du Nouveau-Brunswick dans les Provinces Maritimes du Canada. Notre point de départ consiste à faire état du site de conflit qui oppose les variétés du français acadien et du français laurentien en ce qui concerne les patrons régissant sa sélection. Il a déjà été démontré que les contraintes sémantiques exercent une influence prépondérante en français acadien alors que du côté laurentien, l’effet de ces contraintes est plutôt dépassé par celui venant de contraintes lexicales et morphosyntaxiques. Nos résultats démontrent que le parler acadien à l’étude affiche des parallèles structuraux avec ce qui est rapporté en français laurentien : En plus d’être contraint à un taux variable de sélection, la productivité du subjonctif est limitée à quelques contextes spécifiques et elle n’est pas tributaire de l’effet exercé par des contraintes sémantiques. Nous suggérons qu’il n’y a pas une seule norme vernaculaire partagée par tous les parlers acadiens quant au conditionnement du subjonctif et nous nous interrogeons sur l’impact des contacts dialectaux sur la structure linguistique du français de cette région.
Potential importance of wind patterns and guidance opportunities for the conservation of the Egyptian Vulture Neophron percnopterus in Italy
Authors: Agostini Nicolantonio , Panuccio Michele , von Hardenberg Jost , Monti Flavio 
Published: June 2022

Summary
Movement ecology and environmental factors are topics of paramount importance to consider when planning conservation programmes for target species. Here we discuss this topic by reviewing the available information related to the Egyptian Vulture Neophron percnopterus, with reference to the remnant breeding population of Southern Italy, of high conservation concern and subject of a long-term captive-breeding re-stocking programme. We describe how adverse wind conditions over the Central Mediterranean Sea make the sea-crossing challenging with detrimental effects on the survival of inexperienced birds, and coupled this information with count data of migrating Egyptian Vultures. Furthermore, we indicate how low population size and scarce opportunities in meeting migrating conspecifics could potentially lead juvenile Egyptian Vultures to follow unfavourable migratory routes, with possible repercussions on survival. We postulate how these concomitant factors could be indirectly influencing the long-term survival of this small population, principally affected by anthropogenic threats. We also discuss how the same factors could actually be affecting captive-bred young individuals released in late summer in southern continental Italy, in the framework of the restocking programme. An integrative approach with tailor-made release methods, which also takes into account the age of released birds and geographical and environmental factors, would likely be useful for a more goal-oriented and long-lasting conservation outcome, for the preservation of this endangered scavenger.
Cold stratification in winter is more than enough for seed dormancy-break of summer annuals in eastern North America: implications for climate change
Authors: Baskin Carol C. , Baskin Jerry M. 
Published: June 2022

AbstractGermination of seeds of some summer annuals in Kentucky (eastern USA) in late-winter lead to the hypothesis that under present climate conditions the whole length of the winter cold stratification (CS) period is not required for dormancy-break of seeds of summer annuals with physiological dormancy (PD). We evaluated our data from germination phenology studies of 45 species (69 datasets) and buried-seed studies of 33 species (44 datasets). We determined time and temperature of germination after CS and percentage of the total number of hours of CS during winter (% of winter CS) seeds received prior to start of germination. In the phenology studies, mean temperature during the week of first germination for C3 and C4 species was 11.1 and 14.4°C, respectively, and % of winter CS was 80.8 and 87.4, respectively. In the buried-seed studies, % of CS for C3 and C4 species was 40.8 and 48.1, respectively, when they germinated to 25% at 20/10°C. For 32 of 33 species in the buried-seed studies, the minimum temperature at which seeds germinated decreased with increased CS; thus, seeds had Type 2 non-deep PD. The time of germination is controlled by a number of hours of CS, a decrease in minimum temperature at which seeds can germinate and a temperature increase in early spring. Seeds can germinate at relatively high temperatures as early as December and January, but they continue to be CS until spring. Temperature increases in eastern North America due to global warming are not likely to inhibit the germination of summer annuals with PD in spring.
