Mutual relations between jasmonic acid and acibenzolar-S-methyl in the induction of resistance to the two-spotted spider mite (Tetranychus urticae) in apple trees
Authors: Warabieda Wojciech , Markiewicz M. , Wójcik D. 
Published: August 2020

AbstractThe possibility of inducing resistance to the two-spotted spider mite, Tetranychus urticae Koch, in ‘Gala’ apple trees growing under optimal fertilization or nitrogen-deficiency conditions was investigated. The effects of jasmonic acid (JA) at 1.5 and 2.5 mM, and acibenzolar-S-methyl (benzothiadiazole, BTH) at 0.5 and 1.5 mM, applied separately or together, on the fecundity of T. urticae females in a laboratory test as well as on the population growth of the pest in a greenhouse experiment were determined. The influence of both elicitors on the induction of LOX and PAL gene expression was assessed in a parallel experiment using real-time PCR. Jasmonic acid showed significantly higher effectiveness in inducing apple tree resistance to T. urticae, as compared to BTH. This was particularly evident in the reduction in pest numbers that was observed in the greenhouse experiment and was also confirmed by increased LOX gene expression after treatment with JA. BTH induced the expression of the PAL gene more strongly than jasmonic acid; however, this was not reflected in the performance of the two-spotted spider mite in the laboratory and greenhouse experiments. It was also found that the antagonistic effect of BTH on JA might lead to decreased effectiveness of the jasmonic acid used to induce apple tree resistance to the two-spotted spider mite. Although nitrogen fertilization stimulated the development of spider mite populations, the resistance induction mechanism was more effective in N-fertilized plants, which was especially evident at the higher jasmonic acid concentration.

Published: August 2020

Abstract
Background
Adolescents diagnosed with cancer experience unique psychosocial concerns that persist beyond treatment completion into longer-term survivorship. Camp-based, group Acceptance and Commitment Therapy (ACT) programs are a potential model for providing evidence-informed psychological and peer support to adolescent cancer survivors.

Objective
This paper describes the development and exploration of the feasibility and acceptability of such a program, Places You’ll Go. This manualised program incorporates five 90-min group ACT sessions within a 3-day camp, teaching ACT strategies in the context of psychosocial impacts of cancer.

Method
Eight facilitators and twenty-eight Australian adolescent cancer survivors (68% female; age range 12–17 years, M = 15.4 years) participated in the program and evaluation. Feasibility was assessed using facilitator-reported session duration, attendance, quality and content fidelity; facilitators also completed interviews after program completion. Young people completed surveys on program acceptability at the end of each session and at program completion.

Results
All planned sessions were delivered, with 97% attendance and high fidelity in manualised program delivery. All young people were mostly or very satisfied and would recommend the program to another cancer survivor. Opportunities for peer connection and skill development contributed to perceived program acceptability.

Conclusions
The Places You’ll Go program was acceptable and feasible to deliver. It is a promising community-based model for promoting peer support and well-being in adolescent cancer survivors, indicating the potential of ACT-based approaches for this population. Further work is underway to evaluate whether the program improves psychosocial wellbeing among participants, and if this is linked to the therapeutic mechanisms underpinning ACT.
Oxidative degradation of non-recycled and recycled paper
Authors: Coppola Floriana , Modelli Alberto 
Published: August 2020

AbstractThe degradation of paper-based materials involves several and complex mechanisms, such as hydrolysis and oxidation. The behaviour of different types of pulps can be very variable. In this study, the difference upon oxidation of contemporary non-recycled and recycled papers, which now constitute a considerable fibre source, is investigated. A 0.015 M potassium periodate solution is used to oxidise five types of paper, two non-recycled and three recycled, for 0.5, 1, 2 and 4 h. The effects of such oxidation treatments are evaluated in terms of carbonyl content and degree of polymerisation (DP). A modified procedure of the Szabolcs’s method and viscometry are used to measure the carbonyl content and DP, respectively. The carbonyl groups are found to increase more rapidly in the recycled papers than in the non-recycled ones. On the contrary, oxidation causes a larger decrease of the DP values in the non-recycled papers, the paper made of pure cellulose being the most sensitive in terms of depolymerisation. The DP values measured for pure cellulose paper are in line with previously reported data. Moreover, in accordance with the Ekenstam equation, the plots of the reciprocal of DP as a function of oxidation time show good linear correlations for all types of paper investigated. Pseudo rate constants are thus calculated from the slopes of these plots, those of the non-recycled papers being found to be higher than those of the recycled papers.Graphic abstract
Effects of the antidepressant fluoxetine on pigment dispersion in chromatophores of the common sand shrimp, Crangon crangon: repeated experiments paint an inconclusive picture
Authors: Ford Alex T. , Feuerhelm Eleanor 
Published: August 2020

AbstractThe effects of antidepressants in the environment are starting to generate considerable interest due to the fact that neurotransmitters influence a range of biological processes. Crypsis is an important behavioural and physiological response in many crustaceans modulated by monoamine and pigment dispersing/concentrating hormones. This study aimed to develop a test methodology and investigate the effects of the selective serotonin reuptake inhibitor (SSRI), fluoxetine, on a chromatophore index and overall carapace ‘darkness’ in the common sand shrimp Crangon crangon. Adult shrimp were exposed for either 1 h, 1 day or 1 week across a range of nominal fluoxetine concentrations (10 ng/L, 100 ng/L and 1000 ng/L) and the chromatophore index or carapace percentage ‘darkness’ was recorded following 30 min on white and black substrates. These experiments were repeated three times using different specimens. Animals became significantly darker (~20%) on darker background and lighter on light backgrounds as one might expect. However, time periods over which the animals were recorded had a significant impact on the colouration suggesting habituation to laboratory conditions. Fluoxetine exposure came up as a significant factor in two of the three trials for the chromatophore index but the results was inconsistent between trials. There was a high degree of correlation between the chromatophore index and the percentage darkness analyses however, there was no significant effects for fluoxetine exposure with the percentage darkness data. We conclude that the effects on antidepressants on colour change remain inconclusive from these experiments and we discuss potential areas to improve the repeatability of the experiments.
Relative Reduction in Prevalence (RRP): An Alternative to Cohen’s Effect Size Statistics for Judging Alcohol, Cigarette, and Marijuana Use Prevention Outcomes
Authors: Hansen William B. 
Published: August 2020

AbstractJacob Cohen developed two statistical measures for judging the magnitude of effects produced by an intervention, known as Cohen’s d, appropriate for assessing scaled data, and Cohen’s h, appropriate for assessing proportions. These have been widely employed in evaluating the effectiveness of alcohol, cigarette, marijuana, and other drug prevention efforts. I present two tests to consider the adequacy of using these statistics when applied to drug use prevention programs. I used student survey data from grades 6 through 12 (N = 1,963,964) collected by the Georgia Department of Education between 2015 and 2017 and aggregated at the school level (N = 1036). I calculated effect sizes for an imaginary drug prevention program that (1) reduced 30-day alcohol, cigarette, and marijuana prevalence by 50%; and (2) maintained 30-day prevalence at a pretest level for multiple years. While both approaches to estimating intervention effects represent ideal outcomes for prevention that surpass what is normally observed, Cohen’s statistics failed to reflect the effectiveness of these approaches. I recommend including an alternative method for calculating effect size for judging program outcomes. This alternative method, Relative Reduction in Prevalence (RRP), calculates ratio differences between treatment and control group drug use prevalence at posttest and follow-up, adjusting for differences observed at pretest. RRP allows researchers to state the degree to which an intervention could be viewed as efficacious or effective that can be readily understood by practitioners.

-function given by Ki (Ramanujan J 17(1):123–143, 2008), and we provide new proofs of his results. Our approach is motivated by the ideas of Velásquez (J Anal Math 110:67–127, 2010) in the study of the zeros of certain sums of entire functions with some condition of stability related to the Hermite–Biehler theorem.
Vitamin D supplementation: upper limit for safety revisited?
Authors: Rizzoli René 
Published: August 2020

AbstractVitamin D overdosing includes hypercalcemia, hypercalciuria, and mineral deposits in soft tissues. A safety upper limit of 4000 IU/day, which is consistently accepted, has been challenged, since the risk of adverse events in other systems than calcium-phosphate homeostasis may depend not only on the dose, but on the outcome, the treatment regimen, and possibly the age, sex and vitamin D status. The therapeutic window of vitamin D supplementation may be narrower than hitherto recognized. The prevention and/or correction of vitamin D deficiency/insufficiency with 800–1000 IU/daily of vitamin D or 10 µg/day of calcifediol are safe. Because of their potential harm, larger doses given on the long term or in intermittent regimens should not be selected.
An adaptive algorithm for the transport equation with time dependent velocity
Authors: Dubuis Samuel , Picasso Marco 
Published: August 2020

AbstractAn a posteriori error estimate is derived for the approximation of the transport equation with a time dependent transport velocity. Continuous, piecewise linear, anisotropic finite elements are used for space discretization, the Crank-Nicolson scheme scheme is proposed for time discretization. This paper is a generalization of Dubuis S, Picasso M (J Sci Comput 75(1):350–375, 2018) where the transport velocity was not depending on time. The a posteriori error estimate (upper bound) is shown to be sharp for anisotropic meshes, the involved constant being independent of the mesh aspect ratio. A quadratic reconstruction of the numerical solution is introduced in order to obtain an estimate that is order two in time. Error indicators corresponding to space and time are proposed, their accuracy is checked with non-adapted meshes and constant time steps. Then, an adaptive algorithm is introduced, allowing to adapt the meshes and time steps. Numerical experiments are presented when the exact solution has strong variations in space and time, illustrating the efficiency of the method. They indicate that the effectivity index is close to one and does not depend on the solution, mesh size, aspect ratio, and time step.
Feeling in Control: The Role of Cardiac Timing in the Sense of Agency
Authors: Herman Aleksandra M. , Tsakiris Manos 
Published: August 2020

AbstractThe sense of agency describes the experience of controlling one’s body to cause desired effects in the world. We explored whether this is influenced by interoceptive processes. Specifically, we investigated whether the sense of agency changes depending on where, in the cardiac cycle (systole or diastole), the action was executed and where the outcome of the action occurred. In two experiments, participants completed decision-making task to win/lose money. Explicit (ratings of control) and implicit (temporal judgement) measures of agency were differentially affected by cardiovascular state. Implicit agency scores were affected by the cardiac phase at the point of action execution. Explicit ratings of control were affected by the type of (free vs. instructed) and by outcome valence (win vs. lose). The time of the action was uniformly distributed across the cardiac cycle. These results show interoceptive impact on agency, but that cardiac cycle may affect explicit and implicit agency differently.

Abstract

Background
Gender-affirming hormone therapy and surgery are important medically necessary approaches to transgender care. However, few related data exist in China.

Aim
To understand the desire and access of transgender cares in the Chinese transgender men and women population.

Methods
A cross-sectional self-selecting survey targeting the Chinese transgender population was conducted in 2017 using a snowball sampling method. Participants completed an online questionnaire anonymously. Gender identity was verified by specifically designed questions. Data analysis of this study was performed in 2019.

Outcomes
The main outcome was the status of receiving transgender medical care, including the desire vs actual state of receiving gender-affirming hormone treatment and gender-affirmation surgery, methods of accessing hormonal therapy and surgery, and risky behaviors associated with obtaining treatments.

Results
Of the total 2060 valid questionnaires, there were 1,304 transgender individuals (626 transgender men and 678 transgender women), with a median age of 22 (interquartile range, 19–26) years. Among them, 1,036 (79.4%) expressed desires for hormonal therapy, but of 1,036, 741 (71.5%) considered it difficult to obtain medications from doctors. Of 1,036 individuals, 275 (26.5%) and 172 (16.6%) had thoughts or behaviors of self-injury, respectively, when lacking access to hormone therapy. Of 1,036 individuals, 602 (58.1%) had used hormones. Of those 602 hormone users, 407 (67.6%) had ever obtained medications from informal drug dealers, and 372 (61.8%) of them did not perform regular monitoring. 868 of 1,303 (66.6%) participants had received or wanted to undergo gender-affirming surgeries, but 710 of 868 (81.8%) considered the surgery resources not adequate or very scarce.

Clinical Implications
The transgender medical resources in China are scarce, and many transgender individuals have engaged in high-risk activities to access care.

Strengths & Limitations
This is the first study to focus on the current status of gender-affirming hormone therapy and surgery in the Chinese transgender population, providing valuable and real-world data for understanding the need for transgender health care in China. But, the online questionnaire could not provide the prevalence and other epidemiologic information about transgender individuals in China, and the survey did not address specific medication regimens, dosages, sex hormone levels, and specific hormone therapy–related or surgery-related adverse events.

Conclusion
Significant improvement in access to gender-affirming medical and surgery care is needed in China.
The Shanghai News (1950–1952): New Democracy and External Propaganda in Early 1950s Shanghai
Authors: Howlett Jonathan J. 
Published: August 2020

AbstractThe Shanghai News was the People's Republic of China's (PRC's) first English-language newspaper. The News played an important, but forgotten, role in the development of the PRC's “external propaganda” apparatus, used to fight the ideological Cold War. The News was unusual in that it adopted a commercial business model and juxtaposed vehement anti-imperialist propaganda with advertising for multinational companies from “imperialist-capitalist countries.” This article argues that the News was a product of “New Democracy,” the central political paradigm of the PRC between 1949 and 1953. New Democracy, a policy of cross-class cooperation in the name of national reconstruction, is often dismissed as cynical tactic deployed by the Chinese Communist Party (CCP) to diminish resistance during the takeover of China. The author argues for taking the real world impacts of New Democracy on life and work in early 1950s Shanghai seriously and cautions against teleological narratives.

Published: August 2020

ABSTRACTIn Donald Davidson's Triangulation Argument: A Philosophical Inquiry, Robert H. Myers and Claudine Verheggen spell out, and extensively build on, the triangulation argument advanced by Donald Davidson. This paper is an introduction to a symposium devoted to their development of that argument. The symposium began in 2018 as an authors-meet-critics session at the Canadian Philosophical Association Annual Congress, and consists in the responses of three critics, Kirk Ludwig, Alexander Miller, and Paul Hurley, followed by Verheggen's and Myers's replies. I offer a brief sketch of each of the two parts of the book, and an overview of the questions raised by the critics.
How Does Human Capital Matter? Evidence from Venture Capital
Authors: Gu Lifeng , Huang Ruidi , Mao Yifei , Tian Xuan 
Published: August 2020

AbstractWe examine the effect of labor mobility on venture capital (VC) investment. Following the staggered adoption of the inevitable disclosure doctrine that restricts labor mobility, VCs are less likely to invest in affected states. This effect is more pronounced when human capital is more important to startups, when VC investment is more uncertain, and when VCs’ monitoring costs are higher. The reduced innovation productivity of employees is a plausible underlying mechanism. To mitigate this adverse effect, VCs stage finance startups more and syndicate more with other VCs. Our paper sheds new light on the real effects of labor market frictions.

Abstract
During the coronavirus disease 2019 (COVID-19) pandemic, a new phenomenon manifesting as a multisystem inflammatory syndrome in children (MIS-C) which has a similar clinical presentation to Kawasaki disease, toxic shock syndrome and severe sepsis has emerged. Although the number of MIS-C reports is increasing, rare reports in Asia is still available. To our knowledge, this study is the largest series of published MIS-C cases in Iran. We performed a retrospective study of all patients with case definition for MIS-C admitted to the three paediatric hospitals in Iran. All of these hospitals are located within the most active COVID-19 pandemic areas (Tehran, Qom and Mazandaran) in Iran. Demographic characteristics, clinical data, laboratory findings, imaging and echocardiographic findings, treatment and outcomes were collected. Between 7 March and 23 June 2020, 45 children were included in the study. The median age of children was 7 years (range between 10 months and 17 years). Common presenting symptoms include fever (91%), abdominal pain (58%), nausea/vomiting (51%), mucocutaneous rash (53%), conjunctivitis (51%) and hands and feet oedema (40%) with median duration of symptoms prior to presentation of 5 (interquartile range (IQR) 3, 7) days. Fifty-three percent of children showed lymphopaenia. Overall, the majority of cases at admission had markedly elevated inflammatory markers erythrocyte sedimentation rate (ESR) (95.5%) and C-reactive protein (CRP) (97%). Ferritin was abnormal in 11 out of 14 tested patients (73%), and it was highly elevated (>500 ng/ml) in 47% of cases. Median fibrinogen level was 210 (IQR 165, 291) mg/dl, D-dimer was 3909 (IQR 848, 4528) ng/ml and troponin was 0.6 (IQR 0.1, 26) ng/ml, respectively. Twenty out of 31 patients (64.5%) had hypoalbuminaemia. In addition, hyponatraemia was found in 64% of cases. Twenty-five patients (56%) presented with cardiac involvement and acute renal failure was observed in 13 cases (29%). Pleural, ascitic, ileitis and pericardial effusions were found in 18%, 11%, 4% and 2% of cases, respectively. In conclusion, this is a first large case series of hospitalised children who met criteria for MIS-C in Iran. There was a wide spectrum of presenting signs and symptoms; evidence of inflammation with abnormal values of CRP, ESR, D-dimer, ferritin and albumin; and multi-organ involvement.
Resilience of the rank of random matrices
Authors: Ferber Asaf , Luh Kyle , McKinley Gweneth 
Published: August 2020

AbstractLet M be an n × m matrix of independent Rademacher (±1) random variables. It is well known that if $n \leq m$, then M is of full rank with high probability. We show that this property is resilient to adversarial changes to M. More precisely, if $m \ge n + {n^{1 - \varepsilon /6}}$, then even after changing the sign of (1 – ε)m/2 entries, M is still of full rank with high probability. Note that this is asymptotically best possible as one can easily make any two rows proportional with at most m/2 changes. Moreover, this theorem gives an asymptotic solution to a slightly weakened version of a conjecture made by Van Vu in [17].
