Published: August 2020

Sea cucumbers are an essential fishery resource. Therefore, effective aquaculture methods should be developed to achieve their optimal production. Sea cucumbers are susceptible to various environmental factors, one of which is water quality. Monitoring water quality based on physical and chemical parameters should be useful to the rearing system in aquaculture. In practical use, farmers usually monitor only temperature, salinity, and pH, neglecting the essential role of chemical parameters. This review focuses on and urges the monitoring of physical and chemical parameters. We explored the water quality parameters that may be crucial to the sea cucumber rearing system, including temperature, salinity, pH, dissolved oxygen, ammonia, turbidity, particulate organic matter, total nitrogen, nitrate, nitrite, ammonium, silicate, and phosphate. Furthermore, this paper presents a practical way to monitor the aquaculture or rearing system of sea cucumbers. It is suggested that temperature and salinity are the crucial physical parameters, while the essential chemical parameters are phosphate, nitrate, and ammonia.

Authors: Mohammad AL Felaiw Amjad , Ali Sarah
Published: August 2020

Shopping carts are one of the most important tools for shopping in supermarkets. Shopping carts are used by hundreds of people each day and may be used 7 days per week and sometimes 24 hours per day. This study examined the amount of bacteria present on shopping cart handles before and after using antimicrobial wipes. 40 cart handles from 2 grocery stores in Uniazah city were swabbed. Cart handles were swabbed and then wiped with antimicrobial wipes and swabbed again and samples were transported to the laboratory. After incubation period of 24 hours at 37° C levels of bacteria were measured using a spectrophotometer with absorbency light at 686nm.  24 hours of incubation revealed that absorbency of swabs after antimicrobial wipes, on average was reduced to, about half, compared to, Swabs taken before, antimicrobial wipes. Also, the bacterial counts were less on the cart handles that wipe with antimicrobial wipes. It was concluded that the bacterial load, varied on the carts handles; and that the cart handles that were wiped with antimicrobial wipes had far less bacterial growth than the cart handles that were not wiped with antimicrobial wipes.  Using antimicrobial wipes may be a way to reduce our exposure to harmful bacteria.

Do Survey Estimates of the Public’s Compliance with COVID-19 Regulations Suffer from Social Desirability Bias?
Authors: Larsen Martin , Nyrup Jacob , Petersen Michael Bang
Published: August 2020

The COVID-19 pandemic has led governments to instate a large number of restrictions on and recommendations for citizens’ behavior. One widely used tool for measuring compliance with these strictures are nationally representative surveys that ask citizens to self-report their behavior. But if respondents avoid disclosing socially undesirable behaviors, such as not complying with government strictures in a public health crisis, estimates of compliance will be biased upwards. To assess the magnitude of this problem, this study compares measures of compliance from direct questions to those estimated from list-experiments - a response technique that allows respondents to report illicit behaviors without individual-level detection. Implementing the list-experiment in two separate surveys of Danish citizens (n>5,000), we find no evidence that citizens under-report non-compliant behavior. We therefore conclude that survey estimates of compliance with COVID-19 regulations do not suffer from social desirability bias.

All sea transportation facilities users in the world in general especially in Indonesia always prioritize safety, security and comfort aspects. The ship accidents such as sinking, burning, etc., are problems related to the safety and security of sea transportation.The purpose of this study it was to determine the application of occupational safetyand health inside the speedboat accordance with Ministerial Regulation No. 6 of 2018 concerning Occupational Safety and Health (OSH) in the Ministry of Maritime Affairs and Fisheries.This study used a qualitative method carried out at the port of Tengkayu II, Tarakan City, North Kalimantan were speedboat passengers as the main informants, as well as Transportation Service officers and dock workers as supporting informants.The sampling technique used accidental sampling technique. The results of the study stated that the application of OSH inside the speedboat had not been fully implemented.Passenger awareness is a fundamental cause of the non-implementation of that regulations. One aspect of applying OSH inside the speedboat in accordance with applicable regulations is to use a life jackets while in a speedboat. Passengers only wear life jackets just before leaving when inspected by officers, but will be removed if it is far from the port. Discomfort factor is the main reason why life jackets are not used. In addition, the boat captain's negligence was still found because it did not prioritize the safety of the feeder, and driving was not in accordance with the applicable standard operating procedures.

Formation of nanocrystalline manganese oxide in flames: oxide phase governed by classical nucleation and size-dependent equilibria
Authors: Camacho Joaquin , Dasappa Shruthi
Published: August 2020

Particle nucleation and growth of crystalline manganese oxide nanoparticles was examined in a complementary experimental and modelling study. Gas-to-particle conversion occured in a flame-assisted chemical vapor deposition process whereby a premixed stagnation flame drove the high-temperature synthesis. The structure of the stagnation flame was computed using pseudo one-dimensional and axisymmetric two-dimensional methods to assess the accuracy of using a faster similarity-based calculation for flame-deposition design. The pseudo one-dimensional computation performs reasonably well for the narrow aspect ratio stagnation flow currently studied as evidenced by reasonable agreement between the measured flame position and both computational methods. Manganese oxide nanoparticles having II, II-III, III or IV oxidation states were observed depending on the flame conditions. These observations may be explained by size-dependent equlibria between nano-scale manganese oxide and surrounding gas-phase oxygen. Local equibrium was assessed during the particle temperature-oxygen-time history to gain insight into oxide formation in the flame. Analysis of the saturation ratio for formation of condensed MnO in the flame indicates that nucleation may be limited by a thermodynamic barrier. This nucleation mechanism is supported by measured particle sizes smaller than what would be expected from a coagulation limited growth process. Nanocrystalline MnO, reported here for the first time by flame synthesis, was obtained in oxygen lean flames. MnO2 is the phase predicted to be thermally stable as the particles approach the deposition surface, yet other metastable oxide phases were produced in many of the flames examined. In fact, MnO2 was only observed in the smallest particle size conditions which may indicate that high cooling rates limit phase equilibrium to less massive particles.
Dynamic deformable attention (DDANet) for semantic segmentation
Authors: Rajamani Kumar , Siebert Hanna , Heinrich Mattias P
Published: August 2020

Deep learning based medical image segmentation is an important step within diagnosis, which relies strongly on capturing sufficient spatial context without requiring too complex models that are hard to train with limited labelled data. Training data is in particular scarce for segmenting infection regions of CT images of COVID-19 patients. Attention models help gather contextual information within deep networks and benefit semantic segmentation tasks. The recent criss-cross-attention module aims to approximate global self-attention while remaining memory and time efficient by separating horizontal and vertical self-similarity computations. However, capturing attention from all non-local locations can adversely impact the accuracy of semantic segmentation networks. We propose a new Dynamic Deformable Attention Network (DDANet) that enables a more accurate contextual information computation in a similarly efficient way. Our novel technique is based on a deformable criss-cross attention block that learns both attention coefficients and attention offsets in a continuous way. A deep segmentation network (in our case a U-Net \cite{Jo2019}) that employs this attention mechanism is able to capture attention from pertinent non-local locations and also improves the performance on semantic segmentation tasks compared to criss-cross attention within a U-Net on a challenging COVID-19 lesion segmentation task. Our validation experiments show that the performance gain of the recursively applied dynamic deformable attention blocks comes from their ability to capture dynamic and precise (wider) attention context. Our DDANet achieves Dice scores of 73.4\% and 61.3\% for Ground-Glass-Opacity and Consolidation lesions for COVID-19 segmentation and improves the accuracy by 4.9\% points compared to a baseline U-Net.

Published: August 2020

Objective: Searching the Internet for health-related information is a complex and dynamic goal-oriented process that places demands on executive functions, which are higher-order cognitive abilities that are known to deteriorate with older age. This study aimed to examine the effects of older age on electronic health (eHealth) search behavior, and to determine whether executive functions played a mediating role in that regard. Method: Fifty younger adults (≤ 35 years) and 41 older adults (≥50 years) completed naturalistic eHealth search tasks involving fact-finding (Fact Search) and symptom diagnosis (Symptom Search), a neurocognitive battery, and a series of questionnaires. Results: Multiple regression models with relevant covariates revealed that older adults were slower and less accurate than younger adults on the eHealth Fact Search task, but not on the eHealth Symptom Search task. Nevertheless, executive functions mediated the relationship between older age and eHealth Fact Search and Symptom Search accuracy. Conclusions: Older adults can experience difficulty searching the Internet for some health-related information, which is at least partly attributable to executive dysfunction. Future studies are needed to determine the benefits of training in the organizational and strategic aspects of Internet search for older adults and whether these findings are applicable to clinical populations with executive dysfunction.
Unifying recommendation and active learning for information filtering and recommender systems
Authors: Yang Scott Cheng-Hsin , Rank Chirag , Whritner Jake Alden , Nasraoui Olfa , Shafto Patrick
Published: August 2020

The enormous scale of the available information and products on the Internet has necessitated the development of algorithms that intermediate between options and human users. These AI/machine learning algorithms attempt to provide the user with relevant information. In doing so, the algorithms may incur potential negative consequences stemming from the need to select items about which it is uncertain to increase predictive accuracy versus the need to select items about which it is certain to increase recommendation accuracy. This tension between predicting relevant recommendations to the users and learning about the user's interests can be considered an instantiation of the well-known exploration-exploitation tradeoff in the context of information filtering and recommender systems. Building from existing machine learning algorithms, we introduce a parameterized model that unifies and interpolates between recommending relevant information and active learning. We present three experiments investigating the unified model. Specifically, we illustrate the tradeoffs of optimizing prediction and recommendation within a tightly controlled concept-learning paradigm, show the conditions under which a broad parameter range can optimize for both, and identify the effects of human variability on algorithm performance. Thus, combining methods and models from cognitive science and computer science, we quantify implications of tradeoffs between recommendation accuracy and learning about preferences of human users, demonstrating the value of experimental approaches to understanding real world human-machine feedback loops.
Finding the Power Within: Is Resilience Protective Against Symptoms of Stress, Anxiety, and Depression in Australian Parents During the COVID-19 Pandemic?

Published: August 2020

The present study utilised a strengths-based approach to investigate the association between resilience and indicators of mental health in a large sample of Australian parents at the time of the COVID-19 pandemic. The study was nested within a large longitudinal cohort study of Australian parents of a child aged 0‐18 years. Hierarchical regression models were run to examine the relationship between the variables of interest. Of 2,110 respondents included, 1701 (80.6%) were female. Higher resilience was associated with lower levels of stress, anxiety, and depression. Loneliness was a key contributor to mental health outcomes. An increase in extraversion was associated with improved resilience. The relationship between resilience and depression was influenced by the level of partner support. Interventions targeting mental health of parents at the time of pandemics should focus on reducing loneliness while working with the constraints of imposed social isolation, and to include partners.
Towards a Personalized Multi-Domain Digital Neuro-phenotyping Model for the Detection and Treatment of Mood Trajectories

Published: August 2020

The commercial availability of many real-life smart sensors, wearables and mobile apps provides a valuable information resource about a wide range of human behavioral, physiological and social markers which can be used to infer the user’s mental state and mood. However, there are currently no commercial digital products that integrate these psychosocial metrics with real-time measurement of neural activity. In particular, electroencephalography (EEG) is a well-validated and highly-sensitive neuroimaging method that yields robust markers of mood and affective processing, and has been widely used in mental health research for decades. The integration of wearable neuro-sensors into existing multimodal sensor arrays could hold great promise for deep digital neurophenotyping in the detection and personalized treatment of mood disorders. In this paper we propose a Multi-Domain Digital Neurophenotyping Model which is based on the socio-ecological model of health. The proposed model presents a holistic approach of digital mental health, leveraging on recent neuroscientific advances, and therefore could deliver highly personalized diagnoses and treatments. The technological and ethical challenges of this model are discussed.

Numerous anecdotal reports suggest that domestic violence has increased globally since the COVID-19 pandemic, but rarely are there cross-country empirical support for this claim. Using two unique datasets which comprises official domestic violence data from Southern China (N = 152 daily data points from January 1st to May 31st, 2020) and Google Trends data across four English-speaking countries (i.e., Australia, Canada, the United Kingdom, and the United States; N = 728 daily data points from January 1st to June 30th, 2020), we test the association between daily confirmed cases of COVID-19 and daily reports of domestic violence. We find that daily new cases are positively associated with domestic violence in Australia, Canada, the United Kingdom, and the United States, but not in China. However, one nuance of our findings in China is that this association is lagged. We speculate that it is because that China is the first to experience the pandemic during which many people were not acutely aware of or affected by COVID-19. These findings suggest that the COVID-19 health toll is beyond its direct costs on its infectees and provide insights into social policies on public health crises. Governments need to balance their COVID-19 responses with corresponding assistance toward women and children who might be at risk of domestic violence in this difficult time.

Understanding the number and nature of sexual partners of people with a sexually transmitted infection (STI) helps to better understand the epidemiology of STIs. We conducted a scoping review of the peer reviewed literature (1970-2020) to identify types of intimate relationships and associated sexual partners (‘partnerships). Using a systematic search strategy, we examined 56 out of 15,592 screened papers. Most studies were published within the 21st century, with the majority conducted within the United States of America. Studies used a range of primarily quantitative designs. Initially, we examined the number of partnerships investigated in each included paper to appraise the structure of existing partner typologies. We found that studies tended to focus on one kind of relationship/partner (e.g., ‘casual’) rather than exploring a large range of diverse partnership types. Subsequently we synthesised the types of relationship/partner described by extracting and interpreting the commonalities and differences among reported partnership types. In this way, we were able to develop a spectrum of eight fluid categories of relationships. These categories were; 1) ‘married/committed’; 2) ‘main partner’/’serious partner’/’stable’ or ‘Long term’; 3) ‘steady’; 4) ‘girlfriend’/’boyfriend’; 5) ‘dating’/’going out’; 6) ‘friends with benefits’; 7) ‘fuck buddies’ and ‘booty calls’; and finally: 8) ‘super casual’, ‘hook-ups’, ‘meets and one night stands’. These synthesised categories are useful for those wishing to target and tailor sexual health interventions by relationship/partner type, and to enhance further theoretical research into romantic and intimate relationships.

The theoretical aspects of formation of purposefulness in the students of youth by means of physical education are covered in the article. After all, the modern educational process requires the formation of a purposeful personality with the use of effective traditional and new pedagogical conditions, content, forms and methods of sports and mass work. It has been found that the problem of increasing the efficiency of physical education and health promotion of student youth is one of the most urgent ones. Also, through the analysis of the psychological and pedagogical literature, it is established that the study is necessary for modern youth, since students are less interested in physical education, sports sections, physical education circles and independent classes, etc. Emphasis is placed on the effectiveness of sports and play activities as an effective means of forming students' purposefulness through physical education.

Physical education in institutions of higher education is one of the conditions of comprehensive personality development and an important means of forming the purposefulness and other moral and will qualities of student youth. The study of psychological and pedagogical literature shows that in recent years much attention of Ukrainian scientists has been attracted to the research of the problem of physical education of student youth. However, the problem of targeting in the youth of students with the means of physical education remains unsolved.

Educating students' purposefulness is an extremely important scientific challenge because commitment as a willed quality allows the individual to realize their own desires, needs, interests and motives in pursuit of the goal. It should be emphasized that the effectiveness of students' goal-setting depends on the implementation of a four-stage process of personality ascension and so on.
