Abstract
Introduction
The purpose of this paper is to present an analysis on the energy balance of the hybrid energy system and the mooring scheme for a container ship, as well as the energy balance of the electricity generating systems, from unconventional sources. The methods applied to achieve the main objective consist of analytical calculations and simulations in the ANSYS Fluent program for various positions of the analyzed system, as follows: a) technical characteristics of the container ship; b) elements of the hybrid energy system, which uses unconventional energy; c) energy balance of electricity generating systems from unconventional sources; d) connecting conventional and unconventional power sources to the ship's main power bar.

Results
Finally of researches, the results obtained are: a) the volume, mass and ascending force of the FLETTNER balloon with helium, assimilated with an airship; b) positioning scheme of large vertical wind turbines installed in the bow of the container ship and in the stern of the container ship; c) the energy balance of electricity generating systems from unconventional sources; d) schemes for connecting conventional and unconventional energy sources to the ship.

Conclusions
The calculation of the energy balance of the two types of wind energy capture systems depending on the speed of the ship, in ideal wind conditions and depending on the number of vertical wind turbines running, which use wind energy. Of course, it will never be necessary to turn on all wind power equipment at full capacity. The FLETTNER balloon can generate more power and for this reason, we must to present the number and diameter of cables needed to transmit electricity. Through this research, following the installation of the elements of the hybrid diesel-electric power system with energy from conventional (fossil fuels) and unconventional energy sources (a FLETTNER balloon with helium and four large vertical wind turbines) placed on a ship container portability, both the manoeuvrability and the stability of the ship, do not change fundamentally.
Species determination using AI machine-learning algorithms: Hebeloma as a case study

Published: June 2022

AbstractThe genus Hebeloma is renowned as difficult when it comes to species determination. Historically, many dichotomous keys have been published and used with varying success rate. Over the last 20 years the authors have built a database of Hebeloma collections containing not only metadata but also parametrized morphological descriptions, where for about a third of the cases micromorphological characters have been analysed and are included, as well as DNA sequences for almost every collection. The database now has about 9000 collections including nearly every type collection worldwide and represents over 120 different taxa. Almost every collection has been analysed and identified to species using a combination of the available molecular and morphological data in addition to locality and habitat information. Based on these data an Artificial Intelligence (AI) machine-learning species identifier has been developed that takes as input locality data and a small number of the morphological parameters. Using a random test set of more than 600 collections from the database, not utilized within the set of collections used to train the identifier, the species identifier was able to identify 77% correctly with its highest probabilistic match, 96% within its three most likely determinations and over 99% of collections within its five most likely determinations.

Published: June 2022

AbstractSince it is one of the world's most significant financial markets, the foreign exchange (Forex) market has attracted a large number of investors. Accurately anticipating the forex trend has remained a popular but difficult issue to aid Forex traders' trading decisions. It is always a question of how precise a Forex prediction can be because of the market's tremendous complexity. The fast advancement of machine learning in recent decades has allowed artificial neural networks to be effectively adapted to several areas, including the Forex market. As a result, a slew of research articles aimed at improving the accuracy of currency forecasting has been released. The Long Short-Term Memory (LSTM) neural network, which is a special kind of artificial neural network developed exclusively for time series data analysis, is frequently used. Due to its high learning capacity, the LSTM neural network is increasingly being utilized to predict advanced Forex trading based on previous data. This model, on the other hand, can be improved by stacking it. The goal of this study is to choose a dataset using the Hurst exponent, then use a two-layer stacked Long Short-Term Memory (TLS-LSTM) neural network to forecast the trend and conduct a correlation analysis. The Hurst exponent (h) was used to determine the predictability of the Australian Dollar and United States Dollar (AUD/USD) dataset. TLS-LSTM algorithm is presented to improve the accuracy of Forex trend prediction of Australian Dollar and United States Dollar (AUD/USD). A correlation study was performed between the AUD/USD, the Euro and the Australian Dollar (EUR/AUD), and the Australian Dollar and the Japanese Yen (AUD/JPY) to see how AUD/USD movement affects EUR/AUD and AUD/JPY. The model was compared with Single-Layer Long Short-Term (SL-LSTM), Multilayer Perceptron (MLP), and Complete Ensemble Empirical Mode Decomposition with Adaptive Noise–Improved Firefly Algorithm Long Short-Term Memory. Based on the evaluation metrics Mean Square Error (MSE), Root Mean Square Error, and Mean Absolute Error, the suggested TLS-LSTM, whose data selection is based on the Hurst exponent (h) value of 0.6026, outperforms SL-LSTM, MLP, and CEEMDAN-IFALSTM. The correlation analysis conducted shows both positive and negative relations between AUD/USD, EUR/AUD, and AUD/JPY which means that a change in AUD/USD will affect EUR/AUD and AUD/JPY as recorded depending on the magnitude of the correlation coefficient (r).

Published: June 2022

Background
According to more recent approaches on problematic internet use (PIU), using the internet can be seen as a way of compensating for psychosocial malaise. Taking semiotic cultural psychology theory as its theoretical framework, this study examines the role of affect-laden assumptions concerning the world, known as latent dimensions of sense (LDSs), in promoting (or not) adaptive responses, including internet use as a maladaptive strategy against problems and difficulties.

Aims
To test a theoretical model in which PIU is predicted by LDSs through the mediation of high levels of psychosocial malaise.

Method
We measured PIU (using the Generalized Problematic Internet Use Scale 2), LDSs (View of Context questionnaire), negative affect (Positive and Negative Affect Schedule), social anxiety (Interaction Anxiousness Scale) and loneliness (Italian Loneliness Scale) in 764 Italian adolescents (mean age 15.05 years, s.d. = 1.152 years). LDSs were detected using a multiple correspondence analysis; after confirmatory composite analysis, partial least squares structural equation modelling with higher-order components was performed to test the mediation model.

Results
The results show a relationship between LDSs corresponding to an extreme negative evaluation of the sociocultural context, experienced as absolutely unreliable, and PIU through the mediation of psychosocial malaise (95% CI 0.101– 0.171; P = 0.000).

Conclusions
Overall, the findings suggest that PIU might be a way of compensating for unpleasant states in a context perceived in an extremely negative and homogenising way, i.e. as totally lacking resources and trustworthy people.

Abstract
Purpose
This study aimed to identify patients with pathological complete response (pCR) and make better clinical decisions by constructing a preoperative predictive model based on tumoral and peritumoral volumes of multiparametric magnetic resonance imaging (MRI) obtained before neoadjuvant chemotherapy (NAC).

Methods
This study investigated MRI before NAC in 448 patients with nonmetastatic invasive ductal breast cancer (Sun Yat-sen Memorial Hospital, Sun Yat-sen University, n = 362, training cohort; and Sun Yat-sen University Cancer Center, n = 86, validation cohort). The tumoral and peritumoral volumes of interest (VOIs) were segmented and MRI features were extracted. The radiomic features were filtered via a random forest algorithm, and a supporting vector machine was used for modeling. The receiver operator characteristic curve and area under the curve (AUC) were calculated to assess the performance of the radiomics-based classifiers.

Results
For each MRI sequence, a total of 863 radiomic features were extracted and the top 30 features were selected for model construction. The radiomic classifiers of tumoral VOI and peritumoral VOI were both promising for predicting pCR, with AUCs of 0.96 and 0.97 in the training cohort and 0.89 and 0.78 in the validation cohort, respectively. The tumoral + peritumoral VOI radiomic model could further improve the predictive accuracy, with AUCs of 0.98 and 0.92 in the training and validation cohorts.

Conclusions
The tumoral and peritumoral multiparametric MRI radiomics model can promisingly predict pCR in breast cancer using MRI images before surgery. Our results highlighted the potential value of the tumoral and peritumoral radiomic model in cancer management.
Corporate Ethics: Philosophical Concepts Guiding Business Practices
Authors: Dimitriou Dimitrios 
Published: June 2022

In the highly competitive global market, characterized by rapid political, economic, environmental and technological changes, there has been an increased interest in the role of ethics for shaping corporate actions and highlighting the essential tasks and measures to fulfill two generic missions: support enterprises to make distinctive, lasting and substantial improvements in their performance and build a great firm that attracts, develops, excites and retains exceptional people. This paper addresses the issues arising from opposing forces, namely on the one hand the extremely challenging external environment and on the other hand the increasing demand for responsible business behaviour and ethical decision-making focused on the shared and sustained value creation to serve the interests of all stakeholders, society and the environment. Primary objective is to provide coherent and compact definitions for the key values dealing with professionalism, equality and sustainability that should be clearly defined, thus providing the key drivers for creating a working environment that inspires and motivates employees on one hand; and promote each enterprise socioeconomic footprint in the regional and global business ecosystem. When handling the concepts of responsibility, ethical codes, integrity or trust, philosophy provides an invaluable framework and a foundational basis on which to create and maintain sustainable structures and processes for the business of the new era.

Background: Staphylococcus aureus is commonly found in dairy cows and is a source of contamination in milk. S. aureus that are resistant to beta-lactam antibiotics are referred to as methicillin-resistant Staphylococcus aureus (MRSA). The spread of MRSA cannot be separated from sanitation management during milking; it can originate from milk collected from the udder or from the hands of farmers during the milking process. The purpose of this study was to examine the level of MRSA contamination in dairy cow's milk and farmer's hand swabs. Methods: A total of 109 samples of dairy cow’s milk and 41 samples of farmers’ hand swabs were collected at a dairy farm in Probolinggo, East Java, Indonesia. Samples were cultured and purified using mannitol salt agar (MSA). The profile of S. aureus resistance was established by disk diffusion test using a disk of beta-lactam antibiotics, namely oxacillin and cefoxitin. Results: The S. aureus isolates that were resistant to oxacillin and cefoxitin antibiotics were then tested for oxacillin resistance screening agar base (ORSAB) as a confirmation test for MRSA identity. S. aureus isolates suspected to be MRSA were then tested genotypically by polymerase chain reaction (PCR) method to detect the presence of the mecA gene. The results of the isolation and identification found 80 isolates (53.33%) of S. aureus. The results of the resistance test found that 42 isolates (15%) of S. aureus were resistant to oxacillin and 10 isolates (12.5%) were resistant to cefoxitin. The ORSAB test found as many as 20 isolates (47.62%) were positive for MRSA. In PCR testing to detect the presence of the mecA gene, three isolates (30%) were positive for the mecA gene. Conclusions: This study shows that several S. aureus isolates were MRSA and had the gene encoding mecA in dairy farms.

Background: Excess dietary salt consumption is a major contributor to hypertension and cardiovascular disease. Public education programs on the dangers of high salt intake, and population level interventions to reduce the salt content in foods are possible strategies to address this problem. In Jamaica, there are limited data on the levels of salt consumption and the population’s knowledge and practices with regards to salt consumption. This study therefore aims to obtain baseline data on salt consumption, salt content in foods sold in restaurants, and evaluate knowledge, attitudes, and practices of Jamaicans regarding salt consumption. Methods: The study is divided into four components. Component 1 will be a secondary analysis of data on urinary sodium from spot urine samples collected as part of a national survey, the Jamaica Health and Lifestyle Survey 2016-2017. Component 2 will be a survey of chain and non-chain restaurants in Jamaica, to estimate the sodium content of foods sold in restaurants. Component 3 is another national survey, this time on a sample 1,200 individuals to obtain data on knowledge, attitudes and practices regarding salt consumption and estimation of urinary sodium excretion. Component 4 is a validation study to assess the level of agreement between spot urine sodium estimates and 24-hour urinary sodium from 120 individuals from Component 3. Discussion: This study will provide important baseline data on salt consumption in Jamaica and will fulfil the first components of the World Health Organization SHAKE Technical Package for Salt Reduction. The findings will serve as a guide to Jamaica’s Ministry of Health and Wellness in the development of a national salt reduction program. Findings will also inform interventions to promote individual and population level sodium reduction strategies as the country seeks to achieve the national target of a 30% reduction in salt consumption by 2025.
Sailing against the Law Tides

Published: June 2022

Over the past decade, asylum seekers and refugees arriving in Italy were accommodated in reception facilities located not only in large metropolitan centres but also in Small-medium Towns and Rural Areas (STRAs). Italy’s reception system evolved quickly to face the peaks of asylum applications, especially in the 2015-2017 period. At the same time, the changes in Italy’s reception policies were pushed by the increased polarisation in the asylum debate, which, in turn, has led to great heterogeneity in the development of reception practices.
This paper argues that the reception-territory nexus is a critical dimension to focus on when investigating the implications connected to the arrival and establishment of asylum seekers and refugees. This appears particularly true in STRAs where the reception system provided new resources that, when well-managed, showed transformative potential, developing virtuous interconnections with the local territories and communities. These virtuous interconnections have, however, been affected by the continuous changes in reception policies and came to a critical juncture in 2018, when the so-called Security Decree entered into force. While further modifications are currently underway, such legislation profoundly affected the Italian reception system’s functioning and working principles, creating new frictions and tensions among institutional actors and within the local governance of the reception system itself. We argue that the reform contributed to disrupting, both materially and symbolically, the previous virtuous combination of refugee inclusion and local development, especially in STRAs.
Our situated qualitative analysis – carried out between 2019 and 2020 through discursive in-depth interviews – investigates the interconnections between territory and reception in three small to medium-sized towns and rural areas before and after this regulatory shift. It does so by introducing a novel analytic framework, focusing on symbolic and material aspects within and around reception. The analysis suggests that the stress and disruptions connected to the regulatory changes have had a negative impact on the internal organisation of the reception as well as on the refugees’ inclusion and on the chances of local development.

Policy limitations and constraints to exclusive breastfeeding among working mothers in low- and middle-income countries: the Nigeria case
Authors: Nwaodu-Ufomba Linda 
Published: June 2022

Background/AimsThe rapid increase in Nigeria's female labour participation poses a risk to exclusive breastfeeding. Exclusive breastfeeding is the beneficial process of feeding an infant with breastmilk only during the first 6 months. This study aims to assess the extent to which Nigerian policy addresses barriers and contributes to improved exclusive breastfeeding rates among working mothers in Nigeria.MethodsThe study used a dual qualitative methodological approach, consisting of a literature review and policy analysis. The literature review identified barriers to exclusive breastfeeding among working mothers while the policy analysis evaluated the content of the national policy on infant and young child feeding in Nigeria (2010) and the Labour Act (2004).ResultsThe findings revealed work-related, maternal and social factors were barriers to exclusive breastfeeding. The policy documents addressed these barriers to an extent but showed minimal coherence.ConclusionsThere are still disparities between policies and their implementation, which are attributable to inadequate clarity and insufficient mechanisms to spur policy compliance. The government should adopt evidence-based mechanisms and engage nutritionists in policy formulation and implementation. In addition, maternity leave in Nigeria should be increased to 6 months to allow working mothers to breastfeed. Myths on child nutrition should also be debunked.
The health belief model and self-determination theory in explaining the use of antenatal care services: a cross-sectional study
Authors: Tungaraza Maximillian B , Joho Angelina A 
Published: June 2022

IntroductionAntenatal care services are vitally important in monitoring pregnancy and identifying the risk factors during pregnancy. However, many pregnant women under-use these services and factors associated with under-use are not well explained. Therefore, this study aimed to use the health belief model and self-determination theory to explore antenatal care services use among postnatal women in the Mara region.MethodsA hospital-based cross-sectional study involving postnatal women from April to July 2020 was conducted using a structured questionnaire. A total of 384 postnatal women were recruited using systematic sampling. The associations between constructs of the health belief model and self-determination theories with antenatal care service variables were examined using the Chi-squared test, followed by logistic regression analysis. P<0.05 at 95% confidence interval was considered statically significant.ResultsOf 384 participants, 53.4% were self-determined on antenatal care services use, 46.9% had a high level of perception on antenatal care services use and 49.7% had adequate knowledge on antenatal care services use. Being from the Kurya tribe reduced the odds of being self-determined. Most (85.9%) postnatal women had attended fewer than eight recommended antenatal care visits. Multivariate analysis showed low autonomy (P=0.038), and low perceived barriers (P=0.007) were predictors for antenatal care visits.ConclusionsAntenatal care services are still inadequately used in the Mara region. Low perceived autonomy and low perceived barriers are significantly associated with antenatal care services use. Health management teams and health stakeholders should collaborate to improve the situation.
