Published: December 2020

AbstractAimThis study aimed to adapt the short-form versions of the Parental-Caregivers Perceptions Questionnaire (P-CPQ), and the Family Impact Scale (FIS) in the Finnish language and to test its validity and reliability. Another aim was to compare the background factors of parents with respect to P-CPQ and FIS outcomes.MethodsThis study was conducted among a convenient sample of parents who visited the public dental clinic in Sievi, Finland, from May to October 2016. A total of 54 parents of 2–8-year-old children completed the short-form of the P-CPQ questionnaire and 50 parents of 2–8-year-olds completed the FIS questionnaire while visiting for their children’s routine dental check-up. Parents completed the self-administered P-CPQ and FIS questionnaires. Reliability and validity of the short-form of the P-CPQ and FIS were assessed. Differences between gender, and family size were evaluated using the Mann–WhitneyUtest and the differences between age groups were evaluated using the Kruskal–Wallis one-way ANOVA test.ResultThe Finnish versions of both the short forms of the P-CPQ and FIS had alpha values within the acceptable range. The scales also showed good construct validity. Toddlers (2–4-year olds) had the highest scores for both the P-CPQ and FIS-8 subscales. Likewise, families with 5 or more children had high FIS scores.ConclusionThe short form of the P-CPQ and FIS in Finnish language are valid and reliable. The oral health of the child seems to have the greatest family impact among parents with five or more children and in families with 2–4-year olds.
An ethical intuitionist account of transparency of algorithms and its gradations
Authors: Hayes Paul 
Published: December 2020

AbstractTo make evaluations about the morally relevant impacts of algorithms, transparency is needed. This paper lays out discussion of algorithms and transparency in an explicitly moral analysis with a special focus on the domain of justice and security. The paper provides an account of the moral import of transparency, defined itself as an instrumental value denoting a state of affairs conducive to acquisition of knowledge about some X. A normative account of transparency is outlined relying on an intuitionist framework rooted in the works of Ross and Robert Audi. It will be argued that transparency can be derived as a subsidiary (prima facie) principle from other duties including beneficence and justice and that it is groundable in the value of knowledge. Building on this foundation, the paper examines transparency and duty conflict with a special focus on algorithms in justice and security, recognising that complete transparency can be impossible where duties conflict. It is argued that as a subsidiary (prima facie) principle, transparency is overridable but ineradicable, which is to say that sufficiently justifiable reasons for secrecy or opacity can licence limiting transparency, that is, there may be occasion where full transparency is not our final duty.
Salt Tolerance in the Halophyte Suaeda maritima L. Dum.—the Effect of Oxygen Supply and Culture Medium on Growth
Authors: Alhdad Gazala M. , Flowers Timothy J. 
Published: December 2020

AbstractSuaeda maritima is an annual species that grows in salt marshes and tolerates not only salt but also flooding, although plants are smaller at lower than at higher elevations of salt marshes. We investigated whether adventitious roots play a role in tolerance to flooding and how flooding affects ion accumulation in the shoots, a determinant of growth in this species. We examined the response of plants grown in Stout and Arnon culture solution to different periods of flooding at different salinities and verified our results with plants grown in other culture solutions (Hoagland and Yoshida). We measured growth, photosynthesis and estimated stomatal frequency as well as the accumulation of Na+, Ca2+, Mg2+ and K+: plants grew and photosynthesised optimally in 200-mM Na+ (in Stout and Arnon solution), but the optimal concentration for growth increased to 450 mM when in Yoshida solution. Flooding always decreased growth, but had little effect on Na+ concentrations. Although plants produced adventitious roots, their mass decreased rather than increased with flooding. The decrease in production of adventitious roots under flooded conditions suggested that they were not important in the tolerance of this species to submergence—an unusual response compared with the general response of flooding-tolerant plants.

Abstract
Seabird populations in Antarctica serve as indicators to assess the impacts of global environmental change. Ecological data on seabirds in Antarctica are scarce due to limited knowledge on their distribution and abundance in most parts of the continent. In this study, we investigated the status of seabird species around the Indian research stations Bharati at Larsemann Hills, Prydz bay and Maitri at Schirmacher Oasis, central Dronning Maud Land located in east Antarctica. We conducted primary surveys during austral summers under the Indian Antarctic Program and compiled published as well as unpublished information on seabird distribution from these areas. We employed intensive area search methods to locate presence of seabird nesting and moulting sites. Ten species were recorded from Larsemann Hills with confirmed breeding of snow petrel, south polar skua and Wilson’s storm-petrel. Only south polar skua and Adélie penguin were reported breeding at Schirmacher Oasis with unconfirmed breeding of Wilson’s storm-petrel. This study presents the first detailed synthesis of status of seabirds from Larsemann Hills and Schirmacher Oasis regions in Antarctica and serves as a strong baseline for future ecological work on seabirds in the sector of operation of Indian Antarctic Program.

Published: December 2020

AbstractThe purpose of this exploratory sequential mixed methods research is to (1) analyse research on the problems in music education management in Thailand in the past 5–10 years and (2) explore the current resources of music education in Thai institutions under the Office of The Basic Education Commission (OBEC). The study found that (1) the problems regarding music education in Thailand were lack of experts, lack of music curriculum, lack of musical instruments and proper classrooms, administration systems, lack of budget, lack of music-related activities and disagreement in the perceptions of school directors and teachers; and (2) under the OBEC, there were 30,112 schools in total with 6,781,130 students in the 2018 academic year. As for music teachers, the majority, 68.9%, possess an educational background in music or music education. Overall, most of the schools of all sizes tend to lack Thai, Western and Thai folk musical instruments.
Soft Balancing, Institutions, and Peaceful Change
Authors: Wivel Anders , Paul T. V. 
Published: December 2020

AbstractAs part of the roundtable “International Institutions and Peaceful Change,” this essay examines the role of institutional soft balancing in bringing forth peaceful change in international relations. Soft balancing is understood as attempts at restraining a threatening power through institutional delegitimization, as opposed to hard balancing, which relies on arms buildup and formal alignments. We argue that soft balancing through international institutions can be an effective means to peaceful change, spanning minimalist goals, which aim at incremental change without the use of military force and war, and maximalist goals, which seek more profound change and transformation in the form of continuous interstate cooperation aimed at a more peaceful and just world order. However, the success of soft-balancing strategies in fostering peaceful change varies widely, even in today's globalized and institutionalized international environment. We explore these variations and identify three conditions for success that can inform both academic analysis and political practice: inclusion, commitment, and status recognition. We draw lessons from two historical examples: the Concert of Europe in the early nineteenth century and the League of Nations in the early twentieth century, and discuss how current threats to the liberal international order challenge soft balancing for peaceful change.
Elaboration Tolerant Representation of Markov Decision Process via Decision-Theoretic Extension of Probabilistic Action Language +
Authors: WANG YI , LEE JOOHYUNG 
Published: December 2020

AbstractWe extend probabilistic action language $p{\cal BC}$+ with the notion of utility in decision theory. The semantics of the extended $p{\cal BC}$+ can be defined as a shorthand notation for a decision-theoretic extension of the probabilistic answer set programming language LPMLN. Alternatively, the semantics of $p{\cal BC}$+ can also be defined in terms of Markov decision process (MDP), which in turn allows for representing MDP in a succinct and elaboration tolerant way as well as leveraging an MDP solver to compute a $p{\cal BC}$+ action description. The idea led to the design of the system pbcplus2mdp, which can find an optimal policy of a $p{\cal BC}$+ action description using an MDP solver.
Renewable Energy Federalism in Germany and the United States
Authors: Saurer Johannes , Monast Jonas 
Published: December 2020

AbstractThe Federal Republic of Germany and the United States (US) have adopted different models for energy federalism. Germany allocates more authority to the federal government and the US relies on a decentralized cooperative federalism model that preserves key roles for state actors. This article explores and compares the relevance of federal legal structures for renewable energy expansion in both countries. It sets out the constitutional, statutory, and factual foundations in both Germany and the US, and explores the legal and empirical dimensions of renewable energy expansion at the federal and state levels. The article concludes by drawing several comparative lessons about the significance of federal structures for energy transition processes.

AbstractKochia accessions (designated as KS-4A and KS-4H) collected from a corn field near Garden City, KS, have previously shown multiple resistance to glyphosate, dicamba, and fluroxypyr. These accessions were also suspected as being resistant to photosystem II (PS II) inhibitors. The main objectives of this research were to 1) confirm the coexistence of cross-resistance to PS II inhibitors (atrazine and metribuzin) applied PRE and POST, 2) investigate the underlying mechanism of PS II-inhibitor resistance, and 3) determine the effectiveness of alternative POST herbicides for control of these multiple herbicide–resistant (MHR) kochia accessions. Results from dose-response experiments revealed that the KS-4A and KS-4H kochia accessions were 23-fold to 48-fold resistant to PRE- and POST-applied atrazine and 13-fold to 18-fold resistant to POST-applied metribuzin compared to a known susceptible kochia accession (KS-SUS). Both accessions also showed putative resistance to PRE-applied metribuzin that needs to be confirmed. Sequence analyses of the psbA gene further revealed that all samples from the KS-4A and KS-4H kochia accessions had a Ser264Gly point mutation. A pretreatment with malathion followed by a POST application of atrazine at 1,120 g ha−1 or metribuzin at 630 g ha−1 did not reverse the resistance phenotypes of these MHR accessions. In a separate greenhouse study, alternative POST herbicides, including bicyclopyrone + bromoxynil; bromoxynil + pyrasulfotole; paraquat alone or in combination with atrazine, metribuzin, 2,4-D, or saflufenacil; and saflufenacil alone or in combination with 2,4-D effectively controlled the KS-4H accession (≥97% injury). To our knowledge, this research reports the first case of kochia accessions with cross-resistance to PRE-applied atrazine and POST-applied metribuzin. Growers should adopt diversified weed control strategies, including the use of competitive crops, cover crops, targeted tillage, and harvest weed seed control along with effective alternative PRE and POST herbicides with multiple sites of action to control MHR kochia seedbanks on their production fields.
High Organic Burial Efficiency Is Required to Explain Mass Balance in Earth's Early Carbon Cycle

Published: December 2020

AbstractEarth's carbon cycle maintains a stable climate and biosphere on geological timescales. Feedbacks regulate the size of the surface carbon reservoir, and on million‐year timescales the carbon cycle must be in steady state. A major question about the early Earth is whether carbon was cycled through the surface reservoir more quickly or slowly than it is today. The answer to this question holds important implications for Earth's climate state, the size of the biosphere through time, and the expression of atmospheric biosignatures on Earth‐like planets. Here, we examine total carbon inputs and outputs from the Earth's surface over time. We find stark disagreement between the canonical histories of carbon outgassing and carbon burial, with the former implying high rates of throughput on the early Earth and the latter suggesting sluggish carbon cycling. We consider solutions to this apparent paradox and conclude that the most likely resolution is that high organic burial efficiency in the Precambrian enabled substantial carbon burial despite limited biological productivity. We then consider this model in terms of Archean redox balance and find that in order to maintain atmospheric anoxia prior to the Great Oxidation Event, high burial efficiency likely needed to be accompanied by greater outgassing of reductants. Similar mechanisms likely govern carbon burial and redox balance on terrestrial exoplanets, suggesting that outgassing rates and the redox state of volcanic gases likely play a critical role in setting the tempo of planetary oxygenation.
Statistical Reconstruction of Seasonal Tropical Cyclone Variability in the North Atlantic Basin

Published: December 2020

AbstractSeasonal forecasting of tropical cyclones is a topic of considerable interest to the public, government and private sectors. To improve understanding of the dynamics controlling the predictability of tropical cyclone (TC) activity, and improve the accuracy of forecasts, multiple studies have related TC activity to empirically‐defined indices including the El Niño‐Southern Oscillation, the Atlantic Multidecadal Oscillation, and the North Atlantic Oscillation. These indices were not developed to forecast TC activity but rather summarize other aspects of atmosphere‐ocean variability. In this study we use a statistical approach, based on redundancy analysis, to define two indices related to overall activity and steering of TCs. We focus on North Atlantic TCs that reached tropical storm strength (≥34 kt) between August and October 1948–2016. TC occurrences are binned using an equal area grid that covers the North Atlantic. The redundancy indices are linear combinations of mean sea level pressure for the same season. Cross validation is used to guard against over fitting in the definition of the indices. This approach provides two physically interpretable redundancy indices related to North Atlantic TC activity. The leading redundancy index is used to successfully reconstruct the total number of TCs and the accumulated cyclone energy, over the extended period 1878–2014 using seasonal mean sea level pressures from the National Centers for Environmental Prediction 20th‐Century Reanalysis version 2c. Extensions of the approach for seasonal forecasting are discussed.
Seasonal Variation of Vertical Heat and Energy Fluxes due to Dissipating Gravity Waves in the Mesopause Region Over the Andes
Authors: Guo Yafang , Liu Alan Z. 
Published: December 2020

AbstractVertical energy transports due to dissipating gravity waves in the mesopause region (85–100 km) are analyzed using over 400 h of observational data obtained from a narrow‐band sodium wind‐temperature lidar located at Andes Lidar Observatory (ALO), Cerro Pachón (30.25°S, 70.73°W), Chile. Sensible heat flux is directly estimated using measured temperature and vertical wind; energy flux is estimated from the vertical wavenumber and frequency spectra of temperature perturbations; and enthalpy flux is derived based on its relationship with sensible heat and energy fluxes. Sensible heat flux is mostly downward throughout the region. Enthalpy flux exhibits an annual oscillation with maximum downward transport in July above 90 km. The dominant feature of energy flux is the exponential decrease from 10−2 to 10−4 W m−2 with the altitude increases from 85 to 100 km and is larger during austral winter. The annual mean thermal diffusivity inferred from enthalpy flux decreases from 303 m2 s−1 at 85 km to minimum 221 m2 s−1 at 90 km then increases to 350 m2 s−1 at 99 km. Results also show that shorter period gravity waves tend to dissipate at higher altitudes and generate more heat transport. The averaged vertical group velocities for high, medium, and low frequency waves are 4.15 m s−1, 1.15 m s−1, and 0.70 m s−1, respectively. Gravity wave heat transport brings significant cooling in the mesopause region at an average cooling rate of 6.7 ± 1.1 K per day.

Published: December 2020

AbstractCoastal settings variations are linked to composition, structural, and functional differences among mangrove ecotypes. Basin mangroves undergo larger flooding and salinity fluctuations, yet remain understudied, compared to other ecotypes. We evaluated the effect of flooding and air temperature (T
a) on the surface energy balance and eddy covariance‐derived net CO2 ecosystem exchange (NEE) of a basin mangrove with sporadic freshwater flooding. During the study period (June 2017–November 2018) the site was more frequently not flooded. Under these conditions, in combination with high T
a (>27°C), daytime CO2 uptake was significantly lower, while evapotranspiration and sensible heat flux were higher than when flooded. CO2 uptake increased with T
a and vapor pressure deficit, but after exceeding a threshold (29°C and 1.4 kPa), uptake declined. Flooding extended this T
a threshold by 3°C and increased the radiation saturation point of NEE. The ecosystem is a net sink of CO2 annually (709 ± 09 g C m−2 yr−1), however, it turned a net source of CO2 for 3 months of prolonged rainfall deficit. Most of the precipitation input is returned to the atmosphere (evaporative index: 0.94) and on average, for each gram of atmospheric carbon assimilated into the ecosystem, 2.21 ± 0.50 kg of water was returned to the atmosphere. This ecosystem‐level water‐use efficiency decreased with flooding, but the correlation was not strong. Future temperature increases and lower precipitation (local and regional), combined with lower water table (and/or stronger saline intrusion), imply important losses of primary productivity and stored soil carbon in basin mangroves of northeast Yucatan Peninsula.

Published: December 2020

AbstractForests pass water and carbon through while converting portions to streamflow, soil organic matter, wood production, and other ecosystem services. The efficiencies of these transfers are but poorly quantified. New theory and new instruments have made it possible to use stable isotope composition to provide this quantification of efficiencies wherever there is a measurable difference between the branches of a branchpoint. We present a linked conceptual model that relies on isotopes of hydrogen, carbon, and oxygen to describe these branchpoints along the pathway from precipitation to soil and biomass carbon sequestration and illustrate how it can be tested and generalized.
School-Based Speech-Language Pathologists' Adherence to Practice Guidelines for Assessment of English Learners
Authors: Dubasik Virginia L. , Valdivia Dubravka Svetina 
Published: December 2020

Purpose
The purpose of this study was to ascertain the extent to which school-based speech-language pathologists' (SLPs) assessment practices with individual English learners (ELs) align with federal legislation and professional practice guidelines. Specifically, we were interested in examining SLPs' use of multiple tools during individual EL assessments, as well as relationships between practices and number of types of training experiences.

Method
School-based SLPs in a Midwestern state were recruited in person or via e-mail to complete an online survey pertaining to assessment. Of the 562 respondents who completed the survey, 222 (39.5%) indicated past or present experience with ELs, and thus, their data were included in the analyses. The questionnaire solicited information about respondent's demographics, caseload composition, perceived knowledge and skills and training experiences pertaining to working with ELs (e.g., graduate school, self-teaching, professional conferences), and assessment practices used in schools.

Results

The majority of respondents reported using multiple tools rather than a single tool with
each
EL they assess. Case history and observation were tools used
often
or
always
by the largest number of participants. SLPs who used multiple tools reported using both direct (e.g., standardized tests, dynamic assessment) and indirect tools (e.g., case history, interviews). Analyses revealed low to moderate positive associations between tools, as well as the use of speech-language samples and number of types of training experiences.

Conclusions
School-based SLPs in the current study reported using EL assessment practices that comply with federal legislation and professional practice guidelines for EL assessment. These results enhance our understanding of school-based SLPs' assessment practices with ELs and may be indicative of a positive shift toward evidence-based practice.
