Invitational Rhetoric between Parents and Adolescents: Strategies for Successful Communication

ABSTRACT Successful parent-adolescent communication is crucial to a young person’s well-being and development, but family communication during adolescence is particularly challenging. One type of conversation employs invitational rhetoric, which describes communication where the goal is not to persuade, but to exchange perspectives by creating an atmosphere that establishes safety, value, and freedom. Up to now invitational rhetoric has been used to understand public communication from a rhetorical perspective, but we apply this theory to family communication. To understand invitational rhetoric in families, participants (N = 113) completed a qualitative questionnaire about communication with their parents. Using the critical incident technique participants provided a detailed narrative about a time that they and a parent had a successful conversation about a difficult topic. The results provide a blueprint for understanding what young adults perceive as contributing to invitational conversations with their parents.
Subsequent depression among people with musculoskeletal complaints: a study protocol

Introduction In the Nordic countries, occupational prospective studies on depressive mood disorders are often based on diagnosis codes in psychiatric hospital registers and/or pharmaceutical codes in prescription registers [cf. SBU, 2014]. Several related studies suggest that such outcomes might be influenced by musculoskeletal disorders (MSD) [Fishbain et al., 1997; Magni et al., 1994; Carroll et al., 2003; Patten, 2001; Gerrits et al., 2014], but the strength of the association between MSD and the concerned outcomes has, as far as we know, never been estimated prospectively.
Phraseological Units as a Mirror of National Mentality

The relevance of the study is caused by the continuing interest of linguists to the problem of phraseology as a special – national – sign in the language system, reflecting the national-cultural features of the perception of the world, national mentality, ideological and mental attitudes of native speakers. The analysis of scientific literature showed that the phraseological layer reflecting the national character of a person is rather understudied. In this regard, the purpose of this study is to identify the features of the national mentality of the British based on the analysis of the internal form of phraseological units (PUs), reflecting the nature of a person. In the given study there were analyzed the theoretical works of Russian and foreign linguists on the problems of definition of the term “phraseological unit”; there were analyzed semantic features, sources of origin and figurative bases of the selected PUs; were identified the specific characteristics inherent in the British, based on the frequency parameter of the components of phraseological units. The analysis of figurative sources of PUs, reflecting the national character of a person, revealed a large number of PUs with the following components: zoonyms, somatism, phytonyms and colors (46%); this indicates the national-cultural specificity of PUs, which is expressed in the figurative content of these units and is associated with the cultural and national features of the British. The practical significance of this study is that the results can be used in the lectures and courses of intercultural communication, linguoculturology and lexicology.
On anammox activity at low temperature: effect of ladderane composition, process conditions and dominant anammox population

The application of partial nitritation-anammox (PN/A) under mainstream conditions can enable substantial cost savings at wastewater treatment plants (WWTPs), but how process conditions and cell physiology affect anammox performance at psychrophilic temperatures below 15 °C remains poorly understood. We tested 14 anammox communities, including 8 from globally-installed PN/A processes, for (i) specific activity at 10-30 °C (batch assays), (ii) composition of membrane lipids (U-HPLC-HRMS/MS), and (iii) microbial community structure (16S rRNA gene amplicon sequencing). Crucially, the key parameters impacting anammox activity were the membrane lipid composition and cultivation temperature. The size of ladderane lipids and the content of bacteriohopanoids were key physiological drivers of anammox performance at low temperatures. Higher contents of (i) short C18 [3]-ladderane alkyl and (ii) large phosphatidylcholine headgroup were determined in anammox more active at 15-30 °C and 10-15 °C, respectively. At below 15 °C, the activation energies of most mesophilic cultures severely increased while those of the psychrophilic cultures remained stable; this indicates that the adaptation of mesophilic cultures to psychrophilic regime necessitates months, but in some cases can take up to 5 years. Interestingly, biomass enriched in the marine genus “Candidatus Scalindua” displayed exceptionally highest activity at 10-20 °C (0.50 kg-N.kg-VSS−1.d−1 at 10 °C, Ea10-30 °C = 51±16 kJ.mol−1), indicating outstanding potential for nitrogen removal from cold streams. Collectively, our comprehensive study provides essential knowledge of cold adaptation mechanism, will enable more accurate modelling and suggests highly promising target anammox genera for inoculation and set-up of anammox reactors, in particular for mainstream WWTPs. Highlights Ladderane size and cold exposure affected anammox activation energy (Ea). Ea improved with more C18 [3]-ladderanes over C20 and larger polar headgroup. Long-term cold exposure reduced Ea at 10-15 °C, not activity per se. Marine “Ca. Scalindua” was exceptionally suitable for cold streams. Anammox Ea at 15-30 °C was 79±18 kJ.mol−1. Graphical abstract
Calculation of radium-223 and actinium-225 α-emitter radiopharmaceuticals dose rates in treatment of metastatic castration-resistant prostate cancer

Aim of Study: There is limited information regarding the α-emitter radiopharmaceuticals dose calculation used in the setting of men with prostate cancer (PCa). The present study investigates the α-emitter radiopharmaceuticals absorbed dose distribution in the body organs. Materials and Methods: The α-emitter radiopharmaceuticals dose coefficient and absorbed doses biokinetics distribution, which are used for the treatment of PCa in all over the world, were performed using the “Internal Dose Assessed by Computer” (IDAC-Dose 2.1) program. The results of absorbed dose distribution in any organ of the body, were compared in studied α-emitter radiopharmaceuticals. Results: The absorbed dose value of 223Ra radiopharmaceutical in the prostate organ was evaluated 9.47E-9 Gy/Bq. The maximum and minimum absorbed doses due to biokinetics distribution of 223Ra were found in the thymus (9.53E-8 Gy/Bq) and eye lenses (1.30E-10 Gy/Bq) organs, respectively. Furthermore, the 225Ac absorbed dose in the prostate organ was obtained 1.91E-9 Gy/Bq, where this value is 1% of total body dose. While the absorbed dose distribution of 225Ac in body organs shows the highest concentration in the spleen (1.47E-8 Gy/Bq) and lowest in the eye lenses (7.93E-12 Gy/Bq). Conclusion: The absorbed dose in the body organs due to 223Ra and 225Ac α-emitter radiopharmaceuticals which are used in metastasized castration-resistant prostate cancer (mCRPC), calculated in this study. The results of this study will assist in evaluating and analyzing human body organ doses from application of 223Ra and 225Ac that used in mCRPC patients.
It’s not all rainbows and unicorns: Straight teacher allies reflect on privilege

Abstract The role of allies in social movements is an area of social justice activism that is at times celebrated and at other times contested. Sometimes, allies are celebrated for the “good work” that they do to support marginalized people in their struggle against oppression. They undertake challenging and demanding social justice work, often with little to no institutional support or training motivated by a desire to support all the students they teach. In other circumstances, allies are criticized (in some cases quite appropriately) for being naïve, self-interested, privileged, and—put pejoratively—”do-gooders. ” Despite the discomfort that discussions of allies and their contributions may cause, particularly for some allies themselves, the role that allies play in social movements is an important area of exploration. In this discussion, I argue that teacher allyship needs to be envisioned differently, but not completely discontinued. Drawing on data from interviews with educators in Ontario, I argue that teacher allies must become responsible assets to social justice by resisting the dominant narrative of allyship and strive for on-going reflexivity.
Rheological properties of film solution from cassava starch and kaffir lime oil

Rheology of film solution is important to determine the final characteristics of biopolymer film as packaging material. In this study, the dynamic rheological properties of cassava starch-kaffir lime oil film solution were determined. The rheology measurement was made at frequency of 0.1 to 10 Hz and 1 % strain at 25 °C. The storage modulus (G’), loss modulus (G") and complex viscosity (η*) were determined to know the viscoelastic behavior of the film solution. The magnitude of G’ was greater than G" for all samples which indicated that the film solution was a gel-like; that is, the film solution behaves more like a solid where the deformations were elastic and recoverable. All samples show increasing trend of G’ and G" as the frequency increased. The complex viscosity decreased with increasing frequency which presented a shear thinning behavior of the film solution. The dynamic rheological properties of cassava starch-kaffir lime oil film solution was determined appropriately, thus the characterization of produced biopolymer film by casting can be correlated.

Stylized patterns in implied volatility indices and stock market returns: A cross country analysis across developed and emerging markets

Abstract Purpose: This paper examines the associative and causal relationship between changes in the implied volatility index (VIX) and stock market returns, with data from 15 countries representing both developed and emerging economies.1 We also examine the dynamic variation, if any in the nature of the relationship across bull and bear market swings in these markets. Design/Methodology/Approach: We use daily time series data between January 2013 to July 2019, on VIX and stock index from these countries and employ regression and causality models to explore the nature of the relationship between VIX and stock market movements. We also explore differential patterns, if any, across the countries and bull and bear market cycles in each of these countries. We substantiate our results from the main analysis using a series of robustness tests. Findings: For most countries, we find strong evidence of a negative and asymmetric relationship between the stock market and VIX movement, irrespective of the bear and bull market cycles. We also find that this relation is asymmetric in nature i.e. volatility spikes are more in market downturns than during market upswings. We find strong evidence of the “leverage hypothesis” explaining this asymmetric relation for all countries across all market cycles. We also find weak evidence of reverse causality i.e VIX changes to market movements as per the “volatility feedback hypothesis” holding during bear periods only in developed countries. We suspect that two important pre-conditions of volatility feedback hypothesis to hold, namely volatility persistence and contemporaneous positive volatility return relation might not be holding. We do not find any significant changes in these patterns across bull and bear market cycles. Value: These results indicate that investors can effectively use signals imminent in VIX movements, to determine potential entry and exit points both in emerging as well as developed markets. This should provide them an additional tool in addition to standard analysis approaches before allocating resources in a particular market.
Influence of the Shape of Soft-Iron Yoke on Trapped Field Performance of HTS Bulk

We investigate the influence of soft-iron yokes on the magnetizing characteristics of HTS bulk magnet excited by pulsed field magnetization (PFM). By using the yoke, the trapped field could be improved because the bulk was exposed to the magnetic field for a long time due to hysteresis characteristic. In our previous study, a magnetizing test was performed by using the yokes with different size, resulting that the trapped field of a large yoke was higher than that of a small one. In this study, an effect of the shape of yoke on trapped field performance was evaluated quantitatively. A GdBCO bulk 60 mm in diameter and 20 mm thick was magnetized by using the disk-, ring- and cross-shaped yokes. The trapped field of the cross-shaped yoke was the highest, and that of the ring-shaped yoke was the smallest. However, when the total magnetic flux per unit weight of the yoke was compared, its value of the ring-shaped yoke was a little higher than that of the disk-shaped one. These results provided the possibility of reducing the weight of the system while maintaining the high trapped field by decreasing the volume of soft-iron yoke.
A High-Voltage DC–DC Buck Converter With Dynamic Level Shifter for Bootstrapped High-Side Gate Driver and Diode Emulator

Considering the propagation delay, dVSW/dt immunity, and power dissipation issues in the bootstrapped high-side gate driver design, a monolithic high-voltage dc–dc buck converter with a high-speed dynamic level shifter and improved gate drive buffer is presented in this article. With the introduction of instantaneous dynamic current, the propagation delay of the level shifter is reduced to 1.13 ns for the high-side switch. The dVSW/dt immunity is enhanced by a dynamic current compensation during positive slewing and a diode voltage clamp during negative slewing. The average current consumption of the level shifter is only 8.45 μA at a switching frequency of 1 MHz. The proposed gate drive buffer eliminates the shoot-through current with the use of dead-time control. The compact level shifter and buffer are also used to drive an integrated p-channel mosfet transistor serving as a bootstrap diode emulator. Experimental results show that the fabricated converter with the proposed scheme regulates well with an 18 V input, 1.05 V output, and 2 A load current. Also, high efficiency of up to 93% is achieved.
High-temperature stable piezoelectric transducers using epitaxially grown electrodes

Abstract. Piezoelectric resonators are of great importance for application in high-precision transducers. However, at elevated temperatures, the degradation of commonly used metal electrodes may affect the performance of oxide electrodes of piezoelectric transducers; with sufficiently high electrical conductivity they are expected to overcome this deficit. In the latter case, the stable operation of piezoelectric transducers could be further enhanced if the resonator and electrodes would consist of identical or at least very similar materials; thus, nearly monolithic resonators are created. The present work focuses on two major aspects: the growth of high-quality langasite ( La3Ga5SiO14 ; LGS) and doped LGS thin-film electrode layers by pulsed laser ablation and the characterization of the developed resonator devices. To obtain epitaxial films of the correct stoichiometry, the deposition on heated substrates is performed in oxygen atmosphere in the range from 10 −3 to 10 Pa. Another requirement for adjusting the stoichiometry is an increased Ga content in the sputter targets with respect to LGS to account for Ga evaporation during film deposition. Additional doping with Sr increases the electrode film conductivity; thus combined with the use of low-conductivity single-crystalline catangasite ( Ca3TaGa3Si2O14 ; CTGS) substrates the ratio between the electrical conductivities of the substrate and the film is increased, enabling the preparation of nearly monolithic resonators. The properties of these nearly monolithic resonators are characterized in the temperature range of 600 to 1000 ∘ C and compared to those of CTGS resonator blanks without electrodes. Particular attention is paid to the reproducibility of resonator properties, the electrode orientation and the quality factor. The created nearly monolithic resonator demonstrates stable operation in the temperature range from 600 to 1000 ∘ C.
Early risk factors influencing lung function in schoolchildren born preterm in the era of new bronchopulmonary dysplasia

Advances in perinatal treatment practices—such as antenatal corticosteroids, surfactant replacement therapy, and gentler ventilator modalities—have improved the survival of infants born preterm. Consequently, later morbidity and pulmonary outcome for survivors has attracted increasing interest. The incidence of bronchopulmonary dysplasia (BPD) remains high and the condition is manifesting in infants born at earlier gestational weeks than before. This so-called new BPD results from the arrest of alveolar development and is associated with less structural airway injury and interstitial fibrosis than previously. Long-term follow-up data on lung function, lung structure and respiratory morbidity of children treated with modern methods is insufficiently known. We performed a follow-up study of 88 preterm-born children and 88 matched term-born controls at school age. Children born preterm had lower values in lung function measurements than term-born peers. Reductions were most marked in those with a history of BPD. In accordance with the foetal origins hypothesis, children with intrauterine growth restriction (IUGR) had lower lung function than gestation-controls. This indicates that poor growth in utero is an additional burden on pulmonary health. Both IUGR and BPD predicted lower lung function independently. High-resolution computed tomography of the lung was obtained from 21 children with a history of BPD. Structural abnormalities were common, children with severe BPD being most affected. Preterm children were hospitalised more often than controls, mainly because of wheezing disorders. However, BPD did not influence the hospitalisations. According to the metaanalysis of the contemporary data available, the respiratory outcome of children who had only mild BPD may have improved in comparison to old follow-up data, whereas the results for those without BPD or moderate-to-severe BPD have remained remarkably stable despite progress in treatment practices during early life. In conclusion, preterm children had subtle impairments in lung function at school age. Although they were fairly asymptomatic, concern about the possible long-term effects of preterm birth on pulmonary health is justified. It has been proposed that BPD may predispose individuals to an early COPD-like disorder. Preterm children must be protected from any additional burden on respiratory health and should be monitored appropriately for early detection of lung disease.
Real-Time Perception and Positioning for Creature Picking of an Underwater Vehicle

This study addresses the ability of an underwater vehicle-manipulator system (UVMS) to perceive submarine creatures in the complex undersea environment. A real-time system for Submarine Creature Perception and Positioning (SCPP) based on a binocular vision system is proposed. In particular, we adopt a new Four-Corner Neighborhood Matching Method (FCNMM) to obtain specific target positions. A Fusion Correction Mechanism (FCM) is added to the Kernelized correlation filter (KCF) tracking algorithm to improve tracking performance. Furthermore, SCPP is applied in our UVMS platform to perform seafloor creature picking at the Zhangzidao seafood farm in Dalian, China. The experimental results show the feasibility and robustness of the SCPP system.

Optimal Network Design Applied to Monitoring and Forecasting Surface Temperature in Antarctica

As harsh weather conditions in Antarctica make it difficult to support a dense weather observing network there, it is critical to place new weather stations in locations that are optimal for a given monitoring goal. Here we demonstrate a network design algorithm that uses ensemble sensitivity to identify optimal locations for new automatic weather stations in Antarctica. We define the optimal location as one that maximizes the reduction in total variance of a given spatial field. Using WRF Model forecast output from the Antarctic Mesoscale Prediction System (AMPS), we identify the best locations for observations across the continent by considering two spatial fields: (i) the daily 0000 UTC 2-m temperature analysis field and (ii) the daily 0000 UTC 2-m air temperature 24-h forecast field. We explore the impact of spatial localization on the results, finding that a covariance length scale of 3000 km is appropriate for these metrics. We find optimal locations assuming that no stations exist on the continent (blank slate) and conditional on existing stations (CD90). In the “blank slate” scenario, the Megadunes region emerges as the most important location to both monitor temperature and reduce temperature forecast errors, with the Ronne Coast and the Siple Coast following. Results for the monitoring and forecasting metrics are similar for the CD90 subset as well, indicating that additional stations could benefit multiple performance goals. Considering the CD90 subset, Wilkes Land–Adelie Coast, Ellsworth Land, and Queen Maud Land–Interior are identified as regions to consider installing new stations for optimizing network performance.
