Demand forecasting: an alternative approach based on technical indicator Pbands

Research background: Demand forecasting helps companies to anticipate purchases and plan the delivery or production. In order to face this complex problem, many statistical methods, artificial intelligence-based methods, and hybrid methods are currently being developed. However, all these methods have similar problematic issues, including the complexity, long computing time, and the need for high computing performance of the IT infrastructure. Purpose of the article: This study aims to verify and evaluate the possibility of using Google Trends data for poetry book demand forecasting and compare the results of the application of the statistical methods, neural networks, and a hybrid model versus the alternative possibility of using technical analysis methods to achieve immediate and accessible forecasting. Specifically, it aims to verify the possibility of immediate demand forecasting based on an alternative approach using Pbands technical indicator for poetry books in the European Quartet countries. Methods: The study performs the demand forecasting based on the technical analysis of the Google Trends data search in case of the keyword poetry in the European Quartet countries by several statistical methods, including the commonly used ETS statistical methods, ARIMA method, ARFIMA method, BATS method based on the combination of the Cox-Box transformation model and ARMA, artificial neural networks, the Theta model, a hybrid model, and an alternative approach of forecasting using Pbands indicator. The study uses MAPE and RMSE approaches to measure the accuracy. Findings & value added: Although most currently available demand prediction models are either slow or complex, the entrepreneurial practice requires fast, simple, and accurate ones. The study results show that the alternative Pbands approach is easily applicable and can predict short-term demand changes. Due to its simplicity, the Pbands method is suitable and convenient to monitor short-term data describing the demand. Demand prediction methods based on technical indicators represent a new approach for demand forecasting. The application of these technical indicators could be a further forecasting models research direction. The future of theoretical research in forecasting should be devoted mainly to simplifying and speeding up. Creating an automated model based on primary data parameters and easily interpretable results is a challenge for further research.
Thermal and optoelectronic model of VCSEL arrays for short-range communication

The integration of different components in optoelectronics modules, such as VCSEL and photodiode arrays, optical guides and electronics, introduces optoelectronical, thermal and mechanical interactions. In this context, a thermal and optoelectronic model of VCSEL array is proposed. The self and cross heating of VCSEL arrays have been simulated. The thermal behavior of VCSEL in the array can be modeled by an equivalent circuit model. A small signal electrical equivalent circuit is also presented. This model is obtained from the electrical effects in the component structure and the identification with the rate equations. The models have been validated with 850nm VCSEL arrays characterization.
Estimation of net harmonic currents due to dispersed nonlinear loads within residential areas

The paper deals with the problem of estimating net harmonic currents injected by groups of nonlinear appliances present within typical domestic customers mix. To this aim a simulation based "bottom-up" approach accounting for the cancellation phenomena among individual contributions has been adopted and extended. The nonlinear appliances considered are television set, personal computer, fluorescent and compact fluorescent lamp. The simultaneous operation of linear load has been taken into due account in order to simulate more closely real-life conditions. The simulation results are organised in tables which provide the estimate of main net harmonic currents (3/sup rd/, 5/sup th/ and 7/sup th/) likely to be monitored at the low voltage busbars supplying an end-use area composed exclusively of domestic customers. The validity of the methodology proposed has been tested by comparing simulation results with some field measurements from the residential area investigated.
Bioactive Compounds in Aegopodium podagraria Leaf Extracts and Their Effects against Fluoride-Modulated Oxidative Stress in the THP-1 Cell Line

Aegopodium podagraria L. (goutweed), a member of the Apiaceae family, is a common perennial plant found all around the world that has been used in folk medicine since antiquity. Goutweed leaves contain polyacetylenes, essential oils, mono- and sesquiterpenes, vitamins, macro- and microelements, and phenolic compounds. In spite of its many health-promoting properties, including antioxidant effects, the plant has not been thoroughly studied. The aim of this study was to investigate the antioxidant properties of different goutweed leaf extracts and their effects on the THP-1 cell line, and also to describe the chemical characteristics of goutweed. Falcarinol and falcarindiol and essential oil were determined by gas chromatography coupled with mass spectrometry. Spectrophotometry was used to measure the total content of polyphenols and antioxidant activity–by DPPH and FRAP methods. Oxidative stress in THP-1 cells was induced via sodium fluoride. Then, goutweed leaf extracts were added to evaluate their influence on antioxidant potential (ABTS) and the activity of antioxidant enzymes. Confocal microscopy was used to visualise the production of cytoplasmic and mitochondrial reactive oxygen species (ROS) and for in vitro imaging of apoptosis. The ethanol extracts have a high total content of polyphenols, polyacetylenes, and essential oil, as well as high antioxidant potential. The main volatiles represented diverse chemical groups, which are both oxygenated derivatives of sesquiterpenes and monoterpenes. We also demonstrated positive effects of the high antioxidant potential and increased activity of antioxidant enzymes on cell cultures under severe fluoride-induced oxidative stress. Extraction at 80 ℃ and the use of ethanol as a solvent increased the antioxidant capacity of the extract. The leaves of Aegopodium podagraria may serve as a valuable source of antioxidants in the daily diet and assist in the prevention and treatment of oxidative stress-mediated conditions, e.g., inflammatory conditions, cardiovascular diseases, neurodegenerative diseases, and even obesity.

Many Rivers to Cross: Social Identity, Cognition and Labour Mobility in Rural India

2021 Abstract: By considering the case of rural South India, this study analyses whether individual skills and personality traits are able to facilitate labour market mobility of disadvantaged groups in the presence of constraining social structures. We use an individual panel dataset built on two household surveys carried out in 2010 and 2016-2017 in Tamil Nadu. We explore the relationship between individual cognitive skills (Raven, literacy and numeracy scores), personality traits (Big Five Inventory) and earnings mobility. We first assess the extent of gender and caste-based labour market segmentation using transition matrices. Then, we take advantage of intra-group heterogeneity in terms of cognitive skills and personality traits to explore whether these personal characteristics can enable individuals to overcome rigid social structures. Results show that personality traits are important determinants of labour mobility. Nonetheless, we observe a strong rigidity of the labour market structure in terms of gender and caste, and its relative stillness over
Why don’t employers hire long-term unemployed entitled to a wage subsidy? The employer’s perspective on subsidised employment

Despite a generous system with high wage subsidies for the long-term unemployed and newly arrived immigrants, many Swedish employers do not make use of this opportunity. This study seeks to increase knowledge of why some employers use the opportunity and others do not. Both register and survey data and combined register and survey data are used. One finding is that employers lack information about the subsidy programmes, although employers that had previously employed subsidised workers were much more likely to employ them in the future. Thus, a key policy question is how to present these subsidies to employers to reduce this barrier. The study also found that some employers hired people from these groups from altruistic motives. However, some employers responded that they would not employ a person entitled to a subsidy, regardless of the content of the subsidy scheme.
Prevalence, Trends, and Socioeconomic Determinants of Coexisting Forms of Malnutrition Amongst Children under Five Years of Age in Pakistan

In Pakistan, malnutrition is a chronic issue. Concerns regarding coexisting forms of malnutrition (CFM) in an individual child are emerging, as children suffering from CFM have a 4 to 12-fold higher risk of death compared with healthy children. This study assessed the prevalence, trends, and socioeconomic determinants of various types of CFM using Pakistan Demographic and Health Survey (PDHS) datasets. Data from children aged 0–5 years old, with complete height and weight information, and valid anthropometry, from all regions of Pakistan (except residents of Azad Jammu Kashmir (AJK) and Federally Administered Tribal Areas (FATA), and non-de jure residents), were included. The prevalence of CFM was 30.6% in 2012–2013 and 21.5% in 2017–2018 PDHS. Both PDHSs reported a significantly higher prevalence of CFM in Sindh and Baluchistan compared with other regions of Pakistan. Improved socioeconomic status significantly reduced the odds of various types of CFM, except the coexistence of underweight with wasting. The high prevalence of CFM in Pakistan can be averted by multisectoral collaboration and by integrating nutrition-sensitive and nutrition-specific interventions.

Status of Trace Minerals And Colostral Immunoglobulin’s In Periparturient Goats And Its Significance On Morbidity And Mortality of Goat Kids In Semi-Arid Zone of Northern Plains of India

The present study was designed to evaluate the variations of trace minerals status in blood at different stages of periparturient periods and colostrum and milk, colostrum immunoglobulin’s and morbidity and mortality were also evaluated in various recognized breeds of goats maintained at organized farms of CIRG in comparison to the non-descript goats maintained at farmers field flock. The results reveal that blood, colostrum and milk levels of zinc (Zn), copper (Cu), iron (Fe) manganese (Mn) and cobalt (Co) were found to be significantly lower at different stages of periparturient period in the Non-descript breed of goats of maintained at farmers field flock. The colostrum immunoglobulin’s (IgG, IgM and IgA) were also found to be lowest in the non-descript breed of goats than recognized breeds of goats. The morbidity and mortality were found to be highest in goat kids born of non-descript breed of goats during pre weaning period in comparison to the recognized breeds. It can be concluded that the lower level of trace minerals during periparturient period in non-descript goats of farmers field flocks might results in lower level of colostral immunoglobulin’s hence poor transfer of passive immunity in goat kids. Therefore, high morbidity and mortality of goat kids during pre weaning period than recognized breed of goats of the organized farms.
Designing Parameters of Ion-Implanted Channel Waveguide Using Beam Propagation Method

Channel waveguide formed by multi-energy O2+ ion implantation with different doses is analyzed at both 633 and 1539 nm. It has been demonstrated that the transverse mode number of waveguide is governed by the practical width of the channel waveguide, which depends on not only the channel width from pattern mask, but the lateral straggling of implanted ions. Beam propagation method (BPM) is employed to simulate the possible propagation transverse mode in the waveguides with different widths. The results at 1539 nm show that the waveguide keeps being a single mode waveguide until the width of channel is greater than 15 μm. At 633 nm, TE20 mode can be obtained even the width of channel is very small, and the TE30 mode begins to appear when the width is greater than 9 μm. These simulation results are in good agreement with the experimental results and the calculated results from Marcatilis method.
Relationship between Marriage Immigrant Mothers’ Acculturative Stress and Their Adolescent Children’s Career Decidedness in South Korea: Mediating Roles of Parenting and School Adjustment

International marriages between Korean men and foreign women from other Asian countries have been increasing since the late 1990s in Korea. This study examines the mediating effects of parenting self-efficacy, career-specific parenting behaviors, and school adjustment on the relationship between immigrant mothers’ acculturative stress and their adolescent children’s career decidedness. Data were collected from 1181 third grade students (583 boys, 598 girls) in Korean middle schools and their foreign mothers who participated in the Multicultural Adolescents Panel Study. A structural equation modeling analysis revealed the following multiple mediation process: immigrant mothers’ acculturative stress is indirectly related to their adolescent children’s career decidedness through (1) the dual mediation of parenting self-efficacy and career-specific parenting behaviors; (2) the serial mediation of parenting self-efficacy, career-specific parenting behaviors, and adolescents’ school adjustment; (3) the dual mediation of parenting self-efficacy and adolescents’ school adjustment; and (4) the mediation of adolescents’ school adjustment. This study provides directions for parent education and career counseling to enhance immigrant mothers’ parenting competence and support the positive career development of adolescents from multicultural families. The study, therefore, helps them grow into well-adjusted adults in Korean society, which, in turn, contributes to the well-being of immigrant mothers and their adolescent children.
Epidemiological Profile and Clinicopathological Correlates of Triple Negative Breast Cancer Patients at Regional Cancer Centre

Background: Breast Cancer is the most common cancer among woman worldwide. In India breast cancer remains the leading cause of both incidence and mortality. Triple negative breast cancer is more difficult to treat as it does not respond to hormone therapy medicines or medicines that target receptor proteins (like HER 2 Neu). It is crucial for the physician to know the status of the disease as the patient can be subjected to a whole new avenue of treatment. The present study was done to assess the epidemiological profile and clinicopathological correlates of patients of triple negative breast cancer. Material and Methods: This retrospective study was carried out in Acharya Tulsi Cancer and Research Institute located in the state of Rajasthan, Bikaner, India, among Ca Breast patients presenting to Medical Oncology, Radiation Oncology and Surgical Oncology outdoor & indoor from April 2016 to March 2017. Out of the total 1017 patients of carcinoma breast 957 were included in this Study. Exclusion criteria was non availability of ER, PR, HER2 neu status reports because of various reasons like affordability. Out of the total 957 patients 249 were found to be triple negative. Statistical analysis was done using IBM SPSS version 21. Results: Mean age of the patients was 46±11.23 years. Out of total 249 patients of triple negative breast carcinoma, 91 (%) were found to have had clinical staging I and II (Early stage) and 158 (%) patients were found to have clinical staging III & IV (Late Stage). Mean size of the tumor was 3.6±1.94cm. 151 (60.6%) were pre-menopausal, 103 (41.4%) and 12 (4.8%) patients had positive family history. All of or patients diagnosed to have Ductal type of carcinoma. Lympho-vascular invasion was seen in 51 (20.5%) patients and High grade Histological Grading was seen in High Grade 169 (67.9%) patients. 172 (69.1%) undergone MRM (Modified Radical Mastectomy) and BCS was done in 74 (29.7%) patients. After comparison of triple Negative Breast Cancer with non-triple Negative Breast Cancer, lower age, later stages (III and IV), pre-menopausal status and high grade (on histology) were significantly more in negative type of Ca breast. Occurrence of early Menarche (< 13 Years) and history of OC pills used was almost equal in both the groups. Conclusion: Triple Negative Breast Cancer was found to present at an earlier age and more in pre – menopausal women. Such patients presented with a higher histological grade of tumor and late stage of presentation. There was no statistically significant association between TNBC and age of menarche, use of OC pill, previous exposure to radiotherapy and positive family history in first degree relative.
How Does Health Literacy Modify Indicators of Health Behaviour and of Health? A Longitudinal Study with Trainees in North Germany

Background: Health literacy (HL) is a resource that can help individuals to achieve more control over their health and over factors that influence health. In the present follow-up study, we have investigated the extent to which HL in trainees changes over time and whether or to what extent HL influences health behaviour and health. Methods: In 2017, we performed a baseline survey (T0) of trainees from six different branches, who were contacted through vocational colleges in four northern federal states in Germany. The survey was repeated at the midpoint of their training in 2019 (T1). Demographic data were surveyed, together with information on HL (HLS-EU-Q16), health behaviour and on health status (psychological well-being, subjective health status). Multivariate regression analyses were performed in SPSS 26. Results: Three hundred and ninety-one (391) data sets were evaluated, with a follow-up rate of 27%; 79% of the trainees were female. The mean age was 21.2 years. Over all subjects, the mean HL increased over time (x¯ (SD): 11.9 (2.9) to 12.2 (2.9), p = 0.070). This increase was only statistically significant for the health service trainees (x¯ (SD): 12.1 (2.8) to 12.5 (2.9), p = 0.019). Relative to persons with adequate HL, the odds ratio over time for impaired psychological well-being was increased by 230% in persons with inadequate HL (OR: 3.3, 95% CI: 1.70–6.32, p < 0.001). For persons with problematical HL, the corresponding increase in odds ratio was 110% (OR: 2.1, 95% CI: 1.30–3.38, p = 0.002). Relative to persons with adequate HL, trainees with inadequate HL exhibited a significant increase in odds ratio of 2.8 over time for poor or less good subjective health status (OR: 2.8, 95% CI: 1.23–6.33, p = 0.014). Conclusions: We observed a positive longitudinal association between HL and health. A significant increase in HL was observed in trainees in the health service. Thus the study shows that the concept of HL may provide a potential preventive approach for trainees.
Integrated optic sensor with macro-flow cell

An integrated-optic channel waveguide device is configured as a biosensor. The device measures a refractive index change on the waveguide surface, so it is called a biorefractometer. With an appropriate overlay or selective coating, the device can monitor proteins in blood or pollutants and bio-warfare agents in water. We describe the design, fabrication, and testing of a sensor employing a waveguide Mach-Zehnder interferometer configuration. The device is fabricated in a glass substrate using potassium ion exchange. A patterned glass buffer layer defines the sensing and reference arms of the interferometer. A silicone-rubber macro-flow cell confines the liquid above the integrated-optical waveguide device. Salt solution data show that the biorefractometer has a sensitivity ((Delta) neff/(Delta) nLiquid) of 2 X 10-3 and can measure refractive index changes of about 0.005. Data obtained for antigen-antibody binding of the protein IgG indicate that a 10 percent signal change occurs in approximately 1 minute for a 10 (mu) g/ml concentration level.
