The Effect of Protein Structure and Concentration on Tribocorrosion and Film Formation on CoCrMo Alloys
Authors: Taufiqurrakhman Mohamad , Neville Anne , Bryant Michael G. 
Published: September 2021

AbstractThe formation of tribochemical reaction layers, better known as tribofilms, on cobalt-chromium-molybdenum (CoCrMo) alloys commonly used in orthopaedic applications has been hypothesized to reduce degradation owing to wear and corrosion. However, the mechanisms and pathways influencing tribofilm formation remain largely unknown. This study aims to develop a clearer understanding of the role of protein structures and its concentration on tribocorrosion and surface tribofilms formed on CoCrMo alloys during boundary regime sliding. A reciprocating tribometer with a three-electrode electrochemical cell was employed to simulate and monitor the tribocorrosion of CoCrMo in situ. As-received Foetal Bovine Serum (as-FBS) and pre-heated FBS at 70 °C for 1 h (de-FBS) were diluted with saline (0.9% NaCl) at different concentrations (25% and 75% v/v) and utilized as electrolytes during the tribocorrosion tests. The result shows that the denatured protein structure in electrolyte tends to reduce the volume losses due to wear and corrosion on the CoCrMo samples with an appreciation of the protein tribofilms. On the other hand, an increased protein concentration increased the total volume loss due to corrosive processes. A novel finding revealed in this study is that the tribocorrosion mechanism of the CoCrMo surface is dependent on the protein structure, concentration and sliding duration due to the change in surface condition.
Putting AI ethics to work: are the tools fit for purpose?
Authors: Ayling Jacqui , Chapman Adriane 
Published: September 2021

AbstractBias, unfairness and lack of transparency and accountability in Artificial Intelligence (AI) systems, and the potential for the misuse of predictive models for decision-making have raised concerns about the ethical impact and unintended consequences of new technologies for society across every sector where data-driven innovation is taking place. This paper reviews the landscape of suggested ethical frameworks with a focus on those which go beyond high-level statements of principles and offer practical tools for application of these principles in the production and deployment of systems. This work provides an assessment of these practical frameworks with the lens of known best practices for impact assessment and audit of technology. We review other historical uses of risk assessments and audits and create a typology that allows us to compare current AI ethics tools to Best Practices found in previous methodologies from technology, environment, privacy, finance and engineering. We analyse current AI ethics tools and their support for diverse stakeholders and components of the AI development and deployment lifecycle as well as the types of tools used to facilitate use. From this, we identify gaps in current AI ethics tools in auditing and risk assessment that should be considered going forward.
Coarse ethics: how to ethically assess explainable artificial intelligence
Authors: Izumo Takashi , Weng Yueh-Hsuan 
Published: September 2021

AbstractThe integration of artificial intelligence (AI) into human society mandates that their decision-making process is explicable to users, as exemplified in Asimov’s Three Laws of Robotics. Such human interpretability calls for explainable AI (XAI), of which this paper cites various models. However, the transaction between computable accuracy and human interpretability can be a trade-off, requiring answers to questions about the negotiable conditions and the degrees of AI prediction accuracy that may be sacrificed to enable user-interpretability. The extant research has focussed on technical issues, but it is also desirable to apply a branch of ethics to deal with the trade-off problem. This scholarly domain is labelledcoarse ethicsin this study, which discusses two issues vis-à-vis AI prediction as a type of evaluation. First, which formal conditions would allow trade-offs? The study posits two minimal requisites: adequately high coverage and order-preservation. The second issue concerns conditions that could justify the trade-off between computable accuracy and human interpretability, to which the study suggests two justification methods: impracticability and adjustment of perspective from machine-computable to human-interpretable. This study contributes by connecting ethics to autonomous systems for future regulation by formally assessing the adequacy of AI rationales.
Hard Times: Prostate Cancer Patients’ Experiences with Erectile Aids
Authors: Walker Lauren M. , Sears Carly S. , Santos-Iglesias Pablo 
Published: September 2021

ABSTRACTBackgroundProstate cancer (PCa) treatments commonly lead to erectile difficulties. While the mainstay treatment is erectile aids (EAs) to promote erectile recovery, some men never use these treatments and those whose do use EAs often abandon them in the long-term.AimThe goal of this study was to examine PCa patients’ experiences with EAs, to elucidate relationships between experiences with EAs on psychological and sexual well-being, and to explore benefits and drawbacks to EA use.MethodsA self-report survey including validated questionnaires was administered to examine PCa patients’ use and perceptions of helpfulness of EAs, and to characterize associations between use, perceived helpfulness, and psychological and sexual well-being. The survey was followed by an open-ended prompt to explore participants’ experiences with EAs.OutcomesWe surveyed 260 North American men, up to 25 years after receiving treatment for PCa. Three groups of patients were observed, including those who used EAs and perceived them to be helpful, those who used EAs and perceived them to be unhelpful, as well as a smaller group of patients who never used EAs.RESULTSAround 80% of the sample were using or had used EAs. Despite the high frequency of use, not all men found EAs helpful. Men who used EAs and found them unhelpful reported poorer psychological and sexual well-being compared to men who didn’t use aids or who used EAs but found them helpful. Results indicated both benefits and drawbacks to the use of EAs. Benefits related largely to the efficacy of the aid in promoting erections. A wide range of drawbacks were also reported.Clinical ImplicationsGiven the negative sexual and psychological impacts associated with using EAs and finding them unhelpful, we suggest that researchers and health care providers should take care to proactively address potential challenges that are common with EA use, and also to consider the risks of failed attempts with EAs.Strengths & LimitationsBy using both scaled and open-ended questions, a more nuanced picture of the relative benefits and limitations of EA use within the PCa population is presented. As responses were not mandatory, a subset of participants provided comments about the use of EAs. Additionally, the sample was quite homogenous, with mostly white, American and well-educated participants, so it therefore lacks generalizability to other populations.CONCLUSIONThis paper illustrates several challenges to EA use, while providing insight into reasons for abandonment of use of EAs.

Published: September 2021

ABSTRACTBackgroundLittle is known about pornography use and its relationship with sexual health outcomes in the general population.AimTo assess frequency of pornography use and the association of sexual health outcomes with frequent pornography use in Sweden.MethodsCross-sectional analysis of 14,135 participants (6,169 men and 7,966 women) aged 16–84 years in a Swedish nationally representative survey from 2017. We used logistic regression to assess the association of sexual health outcomes with use of pornography ≥3 times/wk.OutcomesFrequency of pornography use (never; less than once/mo to 3 times/mo; 1–2 times/wk; 3–5 times/wk; and daily or almost daily) and sexual health outcomes (eg, sexual satisfaction and sexual health problems).RESULTSIn total, 68.7% of men and 27.0% of women used pornography. Among men aged 16–24 years, 17.2% used pornography daily or almost daily, 24.7% used pornography 3–5 d/wk and 23.7% used pornography 1–2 d/wk. Among women aged 16–24 years, the proportions were 1.2% for daily or almost daily, 3.1% for 3–5 times/wk, and 8.6% for 1–2 times/wk. Frequency of pornography use decreased with age among both men and women. While 22.6% of all men and 15.4% of all women reported that their or a sex partner’s pornography use predominantly had positive effects on their sex life, 4.7% of men and 4.0% of women reported that the effects were predominantly negative. Variables indicating sexual dissatisfaction and sexual health problems were associated with use of pornography ≥3 times/wk: for example, dissatisfaction with sex life (age-adjusted odds ratio [aOR]: men 2.90 [95% CI 2.40–3.51]; women 1.85 [95% CI 1.09–3.16]), not having sex in the preferred way (aOR: men 2.48 [95% CI 1.92–3.20]; women 3.59 [95% CI 2.00–6.42]) and erection problems (aOR: men 2.18 [95% CI 1.73–2.76]).Clinical ImplicationsWhile frequent pornography use is common, potential effects on sexual health outcomes are likely to differ between individuals.Strength & LimitationsWe used a large and recent nationally representative survey with detailed information regarding frequency of pornography use. The temporality of associations of sexual health variables with frequency of pornography use could not be assessed.CONCLUSIONIn this analysis of a nationally representative survey in Sweden, we found that frequent pornography use was common among young men; that reporting predominantly positive effects of pornography use on the sex life was more common than reporting predominantly negative effects; and that sexual dissatisfaction and sexual health problems were associated with using pornography ≥3 times/wk.
MORE ON THE PRESERVATION OF LARGE CARDINALS UNDER CLASS FORCING
Authors: BAGARIA JOAN , POVEDA ALEJANDRO 
Published: September 2021

AbstractWe prove two general results about the preservation of extendible and
$C^{(n)}$
-extendible cardinals under a wide class of forcing iterations (Theorems 5.4 and 7.5). As applications we give new proofs of the preservation of Vopěnka’s Principle and
$C^{(n)}$
-extendible cardinals under Jensen’s iteration for forcing the GCH [17], previously obtained in [8, 27], respectively. We prove that
$C^{(n)}$
-extendible cardinals are preserved by forcing with standard Easton-support iterations for any possible
$\Delta _2$
-definable behaviour of the power-set function on regular cardinals. We show that one can force proper class-many disagreements between the universe and HOD with respect to the calculation of successors of regular cardinals, while preserving
$C^{(n)}$
-extendible cardinals. We also show, assuming the GCH, that the class forcing iteration of Cummings–Foreman–Magidor for forcing
$\diamondsuit _{\kappa ^+}^+$
at every
$\kappa $
[10] preserves
$C^{(n)}$
-extendible cardinals. We give an optimal result on the consistency of weak square principles and
$C^{(n)}$
-extendible cardinals. In the last section prove another preservation result for
$C^{(n)}$
-extendible cardinals under very general (not necessarily definable or weakly homogeneous) class forcing iterations. As applications we prove the consistency of
$C^{(n)}$
-extendible cardinals with
$\mathrm {{V}}=\mathrm {{HOD}}$
, and also with
$\mathrm {GA}$
(the Ground Axiom) plus
$\mathrm {V}\neq \mathrm {HOD}$
, the latter being a strengthening of a result from [14].
Previous herbivory modulates aphid population growth and plant defense responses in a non-model plant,Carthamus tinctorius(Asteraceae)
Authors: Amiri Domari Motahareh , Mansouri Seyed Mozaffar , Mehrparvar Mohsen 
Published: September 2021

AbstractPlants have a variety of defense mechanisms that are often induced following attacks by herbivores; this benefits those plants by decreasing performance or preference of herbivores that attack the plants later. We investigated the effects of previous exposure of plants to the safflower aphid,Uroleucon carthami, cotton bollworm,Helicoverpa armigera, and mechanical wounding on subsequent safflower aphid infestations using commercial safflower (Carthamus tinctorius) cultivars and wild safflower species (C. oxyacantha). The experiments were conducted in a greenhouse with two treatments: previously induced plants via direct herbivory or mechanical wounding, and control plants that had never experienced herbivory. To test the performance of safflower aphid on different plant treatments, five unwinged aphids were placed on each plant and allowed to reproduce for 14 days. Finally, the total numbers of aphids on each plant were counted and the percentage of produced winged individuals was calculated. The number of aphids on plants that were previously infested or injured was significantly lower than in control plants. Percentage of winged aphids was significantly higher on induced plants, which is an indicator for unsuitable conditions. Also, significant increase in total phenolic content and hydrogen peroxide was observed in induced plants, showing that the levels of these compounds were either treatment, cultivar and/or genotype × treatment dependent, highlighting the specificity of these interactions. Overall, among the safflower cultivars the lowest number of aphids and the highest percentage of winged aphid individuals were observed on Mahali-Isfahan cultivar and wild safflower, showing that this cultivar is more sensitive to herbivory and/or responds to it more than other cultivars. These findings could contribute to a better utilization of induced defense in the integrated pest management of safflower fields.
A meta-analysis of theory of mind and ‘mentalization’ in borderline personality disorder: a true neuro-social-cognitive or meta-social-cognitive impairment?
Authors: Bora Emre 
Published: September 2021

AbstractBackgroundIt is widely accepted that borderline personality disorder (BPD) is associated with significant impairments in mentalization and theory of mind (ToM) which are considered as closely related concepts by many authors particularly in psychoanalytical circles. However, for understanding interpersonal difficulties in personality disorders, it is important to distinguish neuro-social cognitive impairment from the abnormal meta-social-cognitive style of patients.MethodsThe current systematic review aimed to conduct separate meta-analyses of ‘mentalization’ [reflective functioning (RF] and different aspects of ToM in BPD. A literature search was conducted to locate relevant articles published between January 1990 to July 2021. Random-effect meta-analyses were conducted in 34 studies involving 1448 individuals with BPD and 2006 healthy controls.ResultsA very large impairment in RF was evident in BPD [d = 1.68, confidence interval (CI) = 1.17–2.19]. In contrast, ToM impairment was modest (d = 0.36, CI = 0.24–0.48). BPD patients underperformed healthy controls in ToM-reasoning (d = 0.44, CI = 0.32–0.56) but not ToM-decoding. Increased HyperToM (d = 0.60, CI = 0.41–0.79) and faux pas recognition (d = 0.62, CI = 0.35–0.90) errors in BPD compared to healthy controls were most robust ToM findings in this meta-analysis.ConclusionsBPD is characterized by very severe deficits in RF and modest and selective abnormalities in ToM. Interpersonal problems and difficulties in processing social information in BPD can be best explained by patients' maldaptive meta-social cognitive style and top-down effects of these abnormalities rather than having a primary neuro-social cognitive deficit.
ON COMPLEXITY AND DIVERGENCE IN HERITAGE LANGUAGE GRAMMARS
Authors: Perez-Cortes Silvia 
Published: September 2021

AbstractFor more than a decade, research on heritage speakers’ (HSs’) mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it difficult to draw conclusions about HSs’ knowledge of mood distinctions. This study intends to fill this gap by examining Spanish HSs’ (n =76) and Spanish-dominant controls’ (n =25) interpretation and use of an early acquired mood alternation, where the presence of indicative or subjunctive conveys the report of an assertion or a command. Results from two experimental tasks reveal that, even though HSs’ performance tends to differ from that of controls’—especially at lower levels of proficiency—the nature and extent of their divergences suggests the need to embrace a more nuanced analysis of HSs’ linguistic outcomes when examining modal contrasts.
Ultra-processed food consumption, socio-demographics and diet quality in Australian adults

Published: September 2021

AbstractObjective:To examine how socio-demographic characteristics and diet quality vary with consumption of ultra-processed foods (UPF) in a cross-sectional nationally representative survey of Australian adults.Design:Using a 24-h recall, this cross-sectional analysis of dietary and socio-demographic data classified food items using the NOVA system, estimated the percentage of total energy contributed by UPFs and assessed diet quality using the Dietary Guideline Index (DGI–2013 total and components). Linear regression models examined associations between socio-demographic characteristics and diet quality with percentage of energy from UPF.Setting:Australian Health Survey 2011–2013.Participants:Australian adults aged ≥ 19 years (n 8209).Results:Consumption of UPF was higher among younger adults (aged 19–30 years), adults born in Australia, those experiencing greatest area-level disadvantage, lower levels of education and the second lowest household income quintile. No significant association was found for sex or rurality. A higher percentage of energy from UPF was inversely associated with diet quality and with lower DGI scores related to the variety of nutritious foods, fruits, vegetables, total cereals, meat and poultry, fish, eggs, nuts and seeds, legumes/beans, water and limits on discretionary foods, saturated fat and added sugar.Conclusions:This research adds to the evidence on dietary inequalities across Australia and how UPF are detrimental to diet quality. The findings can be used to inform interventions to reduce UPF consumption and improve diet quality.
What is known about human milk bank donors around the world: a systematic scoping review
Authors: Gutierrez dos Santos Bruna , Perrin Maryanne T 
Published: September 2021

Abstract

Objective:
The WHO recommends that low birth weight infants receive donor human milk (DHM) when mother’s milk is not available. Systematic reviews have been published regarding clinical outcomes of infants receiving DHM, as well as the impact of pasteurisation on the composition of DHM; however, information about milk bank donors has not been systematically assessed.

Design:
We conducted a systematic scoping review of original research articles about milk bank donors published before August 2020.

Setting:
Globally.

Participants:
Donors to milk banks.

Results:
A total of twenty-eight studies were included across a variety of geographies: the USA (n 8), Brazil (n 7), Spain (n 4), India (n 2), and single studies in France, Norway, Poland, Italy, Taiwan, Korea and China. Study variables were grouped into six main categories: Donor Demographics (n 19), Clinical Characteristics (n 20), Donor Experiences (n 16), Donation Patterns (n 16), Lifestyle Characteristics (n 4) and Lactation/Breast-feeding History (n 8). Some demographic characteristics were commonly reported across regions, while other, including gender and race, were infrequently explored. Factors that might influence the composition of DHM, including birth timing (term or pre-term), milk type (colostrum, transition or mature) and maternal diet were not regularly studied. Other gaps in the literature included (1) donors’ motivations and barriers to donation, (2) lactation and breast-feeding history, including factors that influence donors to pump and amass surplus milk, and (3) donation patterns, including whether donors are also selling milk to corporations or sharing milk with peers.

Conclusion:
What is known about milk bank donors in different geographies is often limited to a single study, with heterogeneity in the variables reported.
Pricing insurance policies with offsetting relationship
Authors: Hanbali Hamza 
Published: September 2021

AbstractThis paper investigates the benefits of incorporating diversification effects into the pricing process of insurance policies from two different business lines. The paper shows that, for the same risk reduction, insurers pricing policies jointly can have a competitive advantage over those pricing them separately. However, the choice of competitiveness constrains the underwriting flexibility of joint pricers. The paper goes a step further by modelling explicitly the relationship between premiums and the number of customers in each line. Using the total collected premiums as a criterion to compare the competing strategies, the paper provides conditions for the optimal pricing decision based on policyholders’ sensitivity to price discounts. The results are illustrated for a portfolio of annuities and assurances. Further, using non-life data from the Brazilian insurance market, an empirical exploration shows that most pairs satisfy the condition for being priced jointly, even when pairwise correlations are high.
Spatiotemporal Characterization of Mercury Isotope Baselines and Anthropogenic Influences in Lake Sediment Cores

Published: September 2021

AbstractIncreasing mercury isotope ratios from pre‐industrial (1510–1850) to present‐day (1990–2014) in lake sediment cores have been suggested to be a global phenomenon. To assess factors leading to spatiotemporal changes, we compiled mercury concentration (THg) and mercury isotope ratios in 22 lake sediment cores located at various regions of the world. We find that the positive δ202Hg shifts together with THg increases from pre‐industrial to present‐day are a widespread phenomenon. This is caused by increased contribution of mercury from local to regional anthropogenic mercury emission sources, which lead to higher sediment δ202Hg (−1.07 ± 0.69‰, 1 SD) than pre‐industrial sediments (−1.55 ± 0.96‰, 1 SD). The positive Δ199Hg shifts were observed in 15 lake sediment cores, which have low pre‐industrial Δ199Hg (−0.20 ± 0.32‰) compared to the sediment cores with near‐zero to positive pre‐industrial Δ199Hg (0.08 ± 0.07‰). The magnitudes of δ202Hg (r2 = 0.09) and Δ199Hg (r2 = 0.20, both p > 0.05) changes from pre‐industrial to present‐day did not correlate with the magnitude of THg changes. Instead, the magnitudes of δ202Hg and Δ199Hg changes decreased with increasing pre‐industrial δ202Hg and Δ199Hg values, suggesting that the baseline mercury isotope ratios play a more important role in determining the magnitude of mercury isotope changes compared to the degree of THg input. We suggest that the spatiotemporal assessments of δ202Hg in lake sediment cores can be used as an important proxy for monitoring changes in anthropogenic mercury sources for the Minamata Convention on Mercury.
