Authors: Mirkovic Miljana , Maletaskic Jelena , Butulija Svetlana , Andjelkovic Ljubica , Suljagic Marija
Published: March 2023

This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple mixing of acetate solutions of Ce and Sr (with NaH2PO4 at room temperature, and the studied compositions were Ce1-xSrxPO4 (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5). The disintegration of Sr in monazite structures in different sintering temperature ranges from 600 to 1000 ?C was investigated. The X-ray diffraction was used to track the evolution of the phase composition with thermal treatment. The morphology of sintered ceramics was obtained by scanning electron microscopy and vibrational bands of selected spectra were observed using the FT-IR method. Relative geometric density of selected samples was evaluated. The most favorable conditions for obtaining high-temperature Ce, Sr phosphate-based ceramic material are reported.
Heat transfer and mechanical characteristics of the absorber in solar photo-thermal power generation system
Authors: Xiao Zhijun
Published: March 2023

In order to solve the problems of thermal fatigue, high temperature
gasification and low temperature solidification of the heat receiver, a
numerical calculation model for the heat transfer function of the tower type
solar thermal power gener?ation high temperature receiver is proposed. A
perfect analysis method is used for the simulation, and a thermal simulation
program for predicting the heat gain of the solar thermal energy tower is
compiled. In this paper, considering the various field connection
characteristics, numerical value and distribution of convective heat
transfer coefficient of the heat absorption medium, the temperature of the
outer wall of the heat pipe absorption, and the thermal image conversion
work in a non-uniform heat flow boundary area of a model of heat receiver
was studied. The experiments show that when the flow rate of molten salt in
the tube increases from 1 m/s to 2 m/s, the heat collection efficiency of
the heat collection increases rapid?ly, while the flow time is more 3 m/s,
the heat collection efficiency increases more gradually. The efficiency of
heat absorption of the heat receiver is in the middle of the heat receiver,
which can achieve 88 of the thermal image conversion. In the same large
enough value, the heat collected at the inlet and outlet of the heat sink is
about 82. It is clear that the numerical simulation provides a reliable
basis for the design engineering, and provide guidance for the design of a
full control model of tower solar photovoltaic power generation.
Preparation and properties of silicate inorganic external wall insulation materials based on heat storage
Authors: Li Qing , Chen Hao , Li Zhidong
Published: March 2023

In this article, the foaming slurry after the reaction of silicate inorganic
gelling material sodium silicate and foaming agent azodicamide is taken as
the main investigation object, and the mechanism of bubble nucleation and
the effect of physical parameters such as temperature, time, viscosity and
surface tension on the structure of bubble pores are analyzed. As well as
the influence of processing technology such as foiling temperature, heating
rate, holding time and various kinds of modifiers on the structure and
properties of the material, the appropriate processing technology conditions
and modifiers are screened out, and an inorganic foiling insulation material
with light weight, high strength, heat preservation, fire prevention, no
pollution, low cost, simple process and easy to use is prepared. The
experimental results show that, although the properties of the prepared
material are better with the increase of azodicarbonamide (ADC) content and
viscosity, the maximum amount of ADC added is only 1%. When the ADC content
in the system is greater than 1%, the foaming slurry will appear gel, which
is not conducive to the late high temperature foaming and the uniformity of
the final product. Therefore, the optimal amount of ADC is 1% of the mass
of sodium silicate.

Published: March 2023

OBJECTIVE

Previous studies showed that inhibiting lymphocyte costimulation reduces declining β-cell function in individuals newly diagnosed with type 1 diabetes. We tested whether abatacept would delay or prevent progression of type 1 diabetes from normal glucose tolerance (NGT) to abnormal glucose tolerance (AGT) or to diabetes and the effects of treatment on immune and metabolic responses.

RESEARCH DESIGN AND METHODS

We conducted a phase 2, randomized, placebo-controlled, double-masked trial of abatacept in antibody-positive participants with NGT who received monthly abatacept/placebo infusions for 12 months. The end point was AGT or diabetes, assessed by oral glucose tolerance tests.

RESULTS

A total of 101 participants received abatacept and 111 placebo. Of these, 81 (35 abatacept and 46 placebo) met the end point of AGT or type 1 diabetes diagnosis (hazard ratio 0.702; 95% CI 0.452, 1.09; P = 0.11) The C-peptide responses to oral glucose tolerance tests were higher in the abatacept arm (P < 0.03). Abatacept reduced the frequency of inducible T-cell costimulatory (ICOS)+ PD1+ T-follicular helper (Tfh) cells during treatment (P < 0.0001), increased naive CD4+ T cells, and also reduced the frequency of CD4+ regulatory T cells (Tregs) from the baseline (P = 0.0067). Twelve months after treatment, the frequency of ICOS+ Tfh, naive CD4+ T cells, and Tregs returned to baseline.

CONCLUSIONS

Although abatacept treatment for 1 year did not significantly delay progression to glucose intolerance in at-risk individuals, it impacted immune cell subsets and preserved insulin secretion, suggesting that costimulation blockade may modify progression of type 1 diabetes.

Published: March 2023

Elevator traction motors are critical components of elevator systems. After the structural analysis of the traction motor, it is necessary to proceed to the production processes for the comfortable and safe use of elevator systems. In this study, the static load values for bearing lifetime calculation, belt selection, and finite element analyses (FEA) were determined. According to calculated loads; materials, bearings, belt, pulley, brake, and encoder were selected. In order to obtain a design in accordance with elevator standards, motor parts were examined for structural analysis. Finite element analyses were carried out according to the determined maximum static load values, and a new belt elevator traction motor design that provides the safety coefficients has emerged. When the FEA analysis results of bending moments are examined; the maximum Von Mises stress acting on the motor frame and shaft was obtained 17.1 MPa and 27.62 MPa respectively. The maximum Von Mises stress was obtained under the torsional moment as 71.4 MPa and the shaft is 6.1 times safe against a torsional moment. This value is the minimum safety factor of the designed system and safety factors of bending moments are higher than this value. The designed elevator machine has got 12.9 kW rated power, 1.6 m/s cabin speed, and 1175 kg carrying capacity. The advantage of the proposed design is to eliminate the casting process with modular structure via double side belt system. The prototype of the designed motor was produced and it was observed that the motor provided the desired constraints as a result of the loading experiments.

Salient findings of the fourth serological survey of SARS-CoV-2 infections conducted among the age cohort above 10 years in Tamil Nadu (India) have been described. The overall seroprevalence of 87% was reported in the survey done in December 2021, whereas in the first, second, and third surveys, the seropositivity was 32%, 29%, and 70%, respectively. The % share of the antibodies formed due to vaccination in the third and fourth surveys have the contributions of 6.2% and 28.3%, respectively as per the vaccination record of the state since the above given proportion of the state’s population (full population) was fully vaccinated (two-dose) by the time the two surveys were conducted. Age-wise break up of seropositivity of the fourth survey showed that the cohort of 10-18 years had the least (68.4%) seroprevalence and adults above 60 had the highest at 84.5%. The rate of the spread of the virus decreased due to the hybrid immunity developed by infection and vaccination. Using the vaccination and serological data, the % enhancement of the antibodies formed due to vaccination has been worked out in the real world on the ground.
Students’ Satisfaction with Quality of Synchronous Online Learning Under the COVID 19 Pandemic: Perceptions from Liberal Arts and Science Undergraduates
Authors: Majewska Izabela Agata , Zvobgo Varaidzo
Published: March 2023

COVID-19 imposed dramatic changes on educational practices worldwide with American institutions of higher learning moving a significant number of their courses and educational programs to electronic online modes. In the post-pandemic world, the same institutions and educational programs recognize the need to incorporate technological components into their courses. Yet, some disciplines and areas of study may be better equipped for this change than others. The liberal arts are believed to be more reliant on face-to-face interaction and thus can be argued to have been more negatively affected by the required move to synchronous online learning during the pandemic Instructors have the option of teaching online courses either synchronously or asynchronously. As synchronous online learning requires course delivery in real-time via online video conferencing, the hope is that some of the drawbacks associated with teaching liberal arts online can be mitigated with technology-based, face-to-face interaction. In the spirit of exploring the relationship between liberal arts education and synchronous online learning, this research aimed at gauging Jacksonville liberal arts students’ levels of satisfaction with the quality of instruction in synchronously delivered courses during the spring semester of 2021. Informed by the Community of Inquiry theory, of special interest were aspects of synchronous online learning like interaction with the virtual platform (video conferencing), interaction with content, interaction with instructor, and interaction with peers. Three local institutions participated in this study, yielding a sample of 141 students who participated in an anonymous Qualtrics survey pertaining to their learning experiences in the synchronous mode. Using a mixed-methods approach, results show positive perceptions, challenges, and recommendations for synchronous online learning.

Published: March 2023

This paper reports on research that extends knowledge about higher education students’ perceptions of online engagement. In particular, the study aimed to identify what students thought engagement was and how they experienced it. Understanding students’ views about online engagement will provide a more comprehensive understanding of the topic and should assist instructional designers to support academic staff to develop online courses that are more likely to engage their students. Using a mixed-methods approach, the study found that students felt most engaged with learning when doing practical, hands-on activities. Additional findings from the qualitative and quantitative data are highlighted, with some differences between the students’ perceptions in the different types of data, particularly concerning social engagement. This suggests that further research is warranted. The paper offers several practical implications for student learning.
Online Assessment in Higher Education: A Systematic Review
Authors: Heil Joana , Ifenthaler Dirk
Published: March 2023

Online assessment is defined as a systematic method of gathering information about a learner and learning processes to draw inferences about the learner’s dispositions. Online assessments provide opportunities for meaningful feedback and interactive support for learners as well as possible influences on the engagement of learners and learning outcomes. The purpose of this systematic literature review is to identify and synthesize original research studies focusing on online assessments in higher education. Out of an initial set of 4,290 publications, a final sample of 114 key publications was identified, according to predefined inclusion criteria. The synthesis yielded four main categories of online assessment modes: peer, teacher, automated, and self-assessment. The synthesis of findings supports the assumption that online assessments have promising potential in supporting and improving online learning processes and outcomes. A summary of success factors for implementing online assessments includes instructional support as well as clear-defined assessment criteria. Future research may focus on online assessments harnessing formative and summative data from stakeholders and learning environments to facilitate learning processes in real-time and help decision-makers to improve learning environments, i.e., analytics-
A Systematic Review of Studies Exploring Help-Seeking Strategies in Online Learning Environments
Authors: Yang Fan , Stefaniak Jill
Published: March 2023

Adaptive help-seeking as a learning strategy can influence learners' learning outcomes. Learners in online learning environments need more self-regulation and especially more help-seeking strategies. A systematic review was conducted to explore help-seeking strategies in online learning environments. A search on help-seeking strategies in online environments in Educational Research Information Center (ERIC) and PsycInfo yielded 36 peer-reviewed articles that met the inclusion criteria for this study. Karabenick and Knapp’s categories of help-seeking (formal help-seeking, informal help-seeking, instrumental activities, lowering performance aspirations, and altering goals) were used to review the strategies employed by students in online learning. The results show that there is an extreme lack of research on learners’ psychological decision-making process when they lower performance aspirations or alter their goals. Moreover, most studies focus on the learners’ formal and informal help-seeking behaviors in online settings. Since much research has been limited to small case studies that are not always generalizable, future studies are encouraged to include more instructional contexts and personal variables like gender, age, educational background, and mastery of computer skills. To avoid biases that may occur in self-reporting studies, recommendations are made for future studies that use more subjective methods to trace their actual help-seeking behaviors.

Published: March 2023

OBJECTIVE

To determine the environmental persistence of Nannizziopsis guarroi on clinically relevant solid and aqueous substrates.

SAMPLE

2 molecularly confirmed isolates of N guarroi obtained from clinical cases of dermatomycosis in bearded dragons (Pogona vitticeps).

PROCEDURES

3 concentrations (1 McFarland, 1:10 McFarland, and 1:100 McFarland) of fungal suspension were exposed to 7 sterilized solid substrates (fabric aquarium liner, wood mulch, sand, hard plastic, glass, cotton, and stainless steel) and 2 sterilized aqueous substrates (distilled water, saline solution [0.9% NaCl]). Biological replicates were performed for the contamination of the solid substrates. On days 1, 3, and 14 after contamination, the substrates were sampled for fungal culture with technical repeat. Fungal cultures were incubated at room temperature for 10 days and then evaluated for fungal growth.

RESULTS

Data from wood mulch were not evaluated because of plate contamination. Overall, the ability to culture N guarroi from solid substrates was isolate, time, and fungal concentration dependent. Viable fungus was isolated from fabric aquarium liner and glass on day 1 and days 1 and 3, respectively. N guarroi was cultured from all other solid substrates at day 14 from at least 1 isolate and/or fungal concentration. Viable N guarroi was isolated from both aqueous substrates at day 14, regardless of isolate or fungal concentration.

CLINICAL RELEVANCE

The environmental persistence of N guarroi should be considered when treating lizards infected with this fungus. Fomites may contribute to the contagious nature of this pathogen and environmental disinfection should be performed to reduce transmission.

Authors: RUŽIĆ-GORENJEC Nina , KLEMENC KETIŠ Zalika , BLAGUS Rok , POPLAS SUSIČ Antonija
Published: March 2023

Introduction

Not much is known about the fall risk among the adult population of those who rarely visit doctors. We wanted to determine the prevalence of increased fall risk in a population of family practice non-attenders and the factors associated with it.

Methods

We included participants from family medicine practices in this cross-sectional study. To be included in the study, the participants had to be adults living in the community (home-dwelling people) who had not visited their chosen family physician in the last five years (non-attenders). The identification of the eligible persons was done through a search of electronic medical records, which yield 2,025 non-attenders. Community nurses collected data in the participants’ homes. The outcome measure was increased fall risk as assessed by the Morse fall scale: increased risk (≥25) vs. no risk.

Results

The sample consisted of 1,945 patients (96.0% response rate) with a mean age of 60.4 years (range 20.5 to 99.7 years). An increased fall risk was determined in 482 or 24.8% (95% CI: [22.9, 26.8]) of the patients. The multivariate model showed a significant association of increased fall risk with higher age (p<0.001), lower systolic blood pressure (p=0.047), poor family function (p=0.016), increased risk of malnutrition (p=0.013), higher number of chronic diseases (p=0.027), higher pain intensity (p<0.001), lower self-assessment of current health (p=0.002), and higher dependence in daily activities (p<0.001).

Conclusion

Non-attenders may have an increased risk of falling which depends on their health status and age. The inclusion of community nurses in primary healthcare teams could be of use not only to identify the non-attenders’ health needs, but also to better manage their health, especially the factors that were identified to be associated with greater fall risk.

Published: March 2023

Introduction

Students’ mental health is recognised as an important public health issue, and the strict measures and many changes resulting from the COVID-19 pandemic may have exacerbated this. The aims of the study were thus to explore psychological well-being among university students in Slovenia during the beginning of the second lockdown, and to assess associations among their psychological well-being, demographic characteristics, presence of a chronic health condition, and resilience.

Methods

The Slovenian online cross-sectional survey was performed as part of a large-scale international survey led by the COVID-HL Consortium, between the 2nd and 23rd November 2020. The study was carried out on a sample of 3,468 university students (70% female) in Slovenia, aged between 18 to 40 (M=22/SD=3). In addition to sociodemographic data and that on the presence of a chronic health condition, data on subjective social status (SSS), psychological well-being (WHO-5) and resilience (CD-RISC 10) was also gathered.

Results

In our study 52% of university students reported good psychological well-being. Hierarchical binary logistic regression revealed that male, older students, those with higher perceived subjective social status, students without a chronic health condition, and those with higher score on resilience were more likely to have good psychological well-being. Resilience was the strongest predictor of psychological well-being in our study.

Conclusions

Systematic preventive approaches/interventions in the field of mental health should be implemented among students in Slovenia. In this context it is important to develop and deliver programmes for enhancing resilience, which is an important protective factor in times of mental distress.

Aim: The study aimed to investigate the impact of rainwater on the acidity levelsto monitor acid deposition and identify sources of pollutant that affect the acidity concentrations of rainwater. Methodology and Results: One unit of rainwater sampler in each location was employed, andsamples were taken to the National Research and Innovation Agency laboratory (BRIN) for analysis of rainwater quality including acidity/pH degree, conductivity, and ion concentrations. The results show that high rainfall intensity (>300 mm/month) in April and December 2019 led to a decrease in electrical conductivity (<10 mS/cm) and ion compounds (>200 μmol/L) of rainwater, likely due to the dissolution/washing process of anions in the air during the rainy season and acid and alkaline neutralization in the dry season. The most identified chemical compounds were ammonium (NH4+), sulfate (SO42-), nitrate (NO3-), and salt (NaCl). Conclusion, significance, and impact study: Based on back-trajectory projections, the decline in rainwater quality was attributed to both local emissions (transportation, industry, agriculture, and waste burning) and long-range sources (earth crust, oceans, coastlines, marine activities, and anthropogenic and forest fires in the Australian territory).

The growth of the Tangerang area reflects the urban growth trend which leads to a wider growth pattern to the area around the Major City. One indication of the growth is the character changed of settlements that previously had a rural character into urban character, especially in building density. The growth in the number of houses as residences has resulted in changes in the type of open space and its use.  Aim: This research aims to identify the type and character of open spaces in unplanned settlements that are growth very quickly because of the area directly adjacent to the Gading Serpong new town. Methodology and Results: The method used is descriptive qualitative. The type of open space is measured by the criteria of location, form, function, and land status. The character of open space is studied by connecting the existence of open space with the social interaction of the residents of the settlement. Conclusion, significance, and impact of study: The findings that have been obtained from this research are that open spaces have five types with a very prominent spatial character, namely open spaces that arise through natural social processes, are not specially designed and have a very important role in bonding the social interaction of their inhabitants.

No fim de 2019 iniciou-se uma das maiores crises da saúde pública global em Wuhan, China. Essa emergência foi o aparecimento do SARS-CoV-2 e da doença COVID-19, uma síndrome respiratória aguda de alta transmissibilidade. A declaração da pandemia pela OMS em março de 2020 fez com que o mundo tomasse diversas medidas para o combate e contenção da doença. Inicialmente o isolamento social e lockdown foram as principais iniciativas, já que não havia formas de tratamento ou prevenção da doença. Essas medidas restritivas geraram uma mudança de hábito da população que deflagrou sérios comprometimentos físicos e psicológicos. Uma das consequências foi o aumento do uso de substâncias de abuso e, consequentemente, do transtornos por uso de substâncias, dentre elas o tabaco. Durante a pandemia o consumo de cigarro aumentou de 10 a 30% no mundo, o tabagismo é a principal causa de morte evitável e fator de risco para diversas doenças. Conjuntamente ao álcool, a nicotina têm um poder aditivo superior a muitas drogas ilícitas. A combinação dos transtornos por uso de substâncias e a COVID-19 acabam por ter um efeito sinérgico, dessa forma, buscamos integrar aspectos neuroquímicos, cognitivos e comportamentais que levaram ao aumento do consumo e/ou recaída nicotina e a terapêutica utilizada.

Published: March 2023

Background and objectives: Colorectal cancer (CRC) is a disease that begins exclusively in the colon or rectum and is caused by the abnormal growth of glandular epithelial cells within the colon. Homocysteine, vitamin B6, and vitamin D are recognized to play a significant role in colorectal tumor pathogenesis. The aim of this study to investigate serum levels of Hcy, vitamin D and vitamin B6 in colorectal cancer.
Methods: The current study investigated the vital roles of homocysteine, vitamin B6 and vitamin D in cancer development by comparing serum levels of colorectal cancer patients with those of the healthy control group at Nanakaly hospital. The levels of serum homocysteine (Hcy), vitamin B6 and vitamin D in 50 colorectal cancer patients and 50 from the healthy control group have been examined.
Results: The result shows significantly high values of serum homocysteine (p<0.0001) and significant decreases in values of vitamin B6 and vitamin D (p<0.0001and 0.0010) respectively, in patients with CRC when compared with the healthy group.
Conclusions: Our findings demonstrate that increased levels of homocysteine and decreased levels of vitamin B6 and vitamin D could be associated with the pathogenesis and progression of colorectal cancer.
REVIEW OF FEATURE SELECTION METHODS USING OPTIMIZATION ALGORITHM
Authors: Hamad Zana O.
Published: March 2023

Many works have been done to reduce complexity in terms of time and memory space. The feature selection process is one of the strategies to reduce system complexity and can be defined as a process of selecting the most important feature among feature space. Therefore, the most useful features will be kept, and the less useful features will be eliminated. In the fault classification and diagnosis field, feature selection plays an important role in reducing dimensionality and sometimes might lead to having a high classification rate. In this paper, a comprehensive review is presented about feature selection processing and how it can be done. The primary goal of this research is to examine all of the strategies that have been used to highlight the (selection) selected process, including filter, wrapper, Meta-heuristic algorithm, and embedded. Review of Nature-inspired algorithms that have been used for features selection is more focused such as particle swarm, Grey Wolf, Bat, Genetic, wale, and ant colony algorithm. The overall results confirmed that the feature selection approach is important in reducing the complexity of any model-based machine learning algorithm and may sometimes result in improved performance of the simulated model.

Published: March 2023

Background and objectives: Psychological disturbance is one of the most significant feature amongst individuals who are served military tasks. This study presented the Post Traumatic Disorder (PTSD) among the peshmargas (Kurdish military personnel) who joined in ISIS war. The aim of this study is to determine the prevalence of post-traumatic stress disorder among peshmargas returning from war and to identify the associated factors of PTSD among the study sample.
Methods: A purposive sample of 113 peshmargas had been studied during the period 1st of January to 1st of June 2018. The participants’ responses to the PTSD Checklist had been recorded by the researchers.
Results: The study revealed that 21.24% of peshmargas suffered from some symptoms of PTSD, more than half (52.21%) of them suffered from moderately to moderately high severity symptoms, and (26.55%) of them suffered from high severity of PTSD.

Chemical space maps help visualize similarities within molecular sets. However, there are many different molecular similarity measures resulting in a confusing number of possible comparisons. To overcome this limitation, we exploit the fact that tools designed for reaction informatics also work for alchemical processes that do not obey Lavoisiers principle, such as the transmutation of lead into gold. We start by using the differential reaction fingerprint (DRFP) to create tree-maps (TMAPs) representing the chemical space of pairs of drugs selected as being similar according to various molecular fingerprints. We then use the Transformer-based RXNMapper model to understand structural relationships between drugs, and its confidence score to distinguish between pairs related by chemically feasible transformations and pairs related by alchemical transmutations. This analysis reveals a diversity of structural similarity relationships that are otherwise difficult to analyze simultaneously. We exemplify this approach by visualizing FDA-approved drugs, EGFR inhibitors, and polymyxin B analogs.

Günümüz turizm çeşitliliği içerisinde gastronomi turizmi büyük önem taşımaktadır. Pek çok kişi yeme- içme nedeniyle mutfak kültürünün zengin olduğu ülke veya bölgelere seyahat planlarını yapmaktadır. Kıbrıs, yeme-içme kültürü olarak oldukça zengin Akdeniz'in üçüncü büyük adasıdır. Bu araştırmada birinci amaç, gastronomi turizmi kapsamında Kıbrıs yeme-içme kültüründe meyhanelerin lezzetlerini açıklamaktır. İkinci amaç ise Kıbrıs yemek kültüründe büyük öneme sahip olan tatların tanıtılması ve Kıbrıs'a gelecek turistlerin tatmaları gereken lezzetler konusunda ön bilgi sahibi olmalarına yardımcı olmaktır. Daha önce yapılan çalışmaların Literatür taramasında, Kıbrıs tavernalarının lezzetleri hakkında yeterli sayıda akademik çalışma bulunamamaktadır. Dolayısıyla, yapılan çalışma, farklı medeniyetlere ev sahipliği yapmış olan Kıbrıs ve Kıbrıs mutfağının lezzetlerine çok güzel bir örnek oluşturarak literatüre katkı sağlayacaktır. Çalışmanın bütünlüğünü sağlamak için genel olarak Kıbrıs Mutfağı ile ilgili bir literatür taraması yapılmıştır. Araştırmada, Nitel araştırma yöntemlerinden bire bir görüşme tekniği kullanılarak Kuzey Kıbrıs Türk Cumhuriyeti’nin Gazimagusa ve İskele bölgelerinde yer alan meyhanelerden veri toplanmıştır. Görüşmeler, 20-30 dk . arasında röportaj şeklinde gerçekleşmiştir. Bu çalışma, meze kültürünün Kıbrıs halkı tarafından benimsendiği ve genel olarak tüm meyhanelerde bulunan mezeler ve tarifleri hakkında meyhane sahiplerinin bilgi sahibi oldukları bununla birlikte turist olarak gelenlere kıbrıs mutfağını ve mezelerini bilinçli olarak bilgilendirildiği ortaya çıkarak gelecek nesillere Kıbrıs mezeleri ve tarifi hakkında katkı sağlamış ve sonuçlamıştır.

The aim of the study is to identify the structure of consumer preferences for attributes of organic coffee and determine the implicit price or willingness to pay for each attribute in Mexico. The database comes from the application of repeated experimental survey to organic coffee consumers of Tianguis in Chapingo, Mexico State. The first objective was identified by the method of choice experiments (EE) and the second with a multinomial logit. We concluded that consumers prioritize first and prefer coffee with Good Quality and Safety with an implicit price of $ 48.50; second, they prefer coffee produced with good agricultural practices with an implicit price of $ 23.50, and ultimately, consumers choose coffee produced with good possibility of traceability with an implicit price of $ 20.00; while total willingness to pay (DAP) of $ 92 approximately for organic coffee packaging 500g. From these results it is recommended to coffee producers in order of priority; first improve quality and safety of coffee; second strengthening actions that promote good agricultural practices and finally implement the traceability in the production and marketing of organic coffee.

The objective of this study is to estimate the impact of the Juntos program on the levels of domestic violence against women. Certainly, violence is a complex phenomenon and is determined by multiple causes; although it is true, within the objectives of the Juntos program, the reduction of domestic violence is not directly envisaged. However, a group of studies warn that one of the causes of violence against women is for economic reasons and there are three types of domestic violence: physical, psychological and sexual. Specifically, the Juntos program is a social program aimed at the most vulnerable population, in situations of extreme poverty, risk and exclusion; the subsidy consists of the monthly delivery of 100 soles. The study follows a quantitative methodology because of the need to empirically demonstrate the impact of the program, specifically the technique of Propensity Score Matching: Nearest Neighbor Matching and the data source used for the analysis is the National Survey of Demography and Family Health - ENDES of the years 2014 and 2015. The results indicate that the Juntos program has not managed to reduce the levels of domestic violence to a level of significance of 5%, it does not report a favorable impact of the program in the reduction of physical, psychological and sexual violence either in severe form or sometimes; however, the number of beneficiary households has increased exponentially during the 10 years of operation. The results suggest incorporating into the health component of the Juntos program the mental health of the beneficiary households, for this the participation of the woman and her partner is important, the condition or commitment is to modify the behavior of the couple in acts or attitudes of violence.
Un modelo de oferta exportable para productos no tradicionales del Perú: periodo 2004 - 2016
Authors:   Universidad Nacional del Altiplano, Puno, Perú, Lazo Flores Froilán
Published: March 2023

In the last fifteen years, non-traditional exports from Peru have gone from a value of US $ 2 044 million in the year 2000, to US $ 10 857 in 2015; which means a total growth of 430% and an average annual growth of 28%. This is partly due to the diversification of the exportable supply, the competitive advantages that each export sector has and to the Trade Agreements (Free Trade Agreements) of Peru with different countries and economic blocs. This document presents an econometric model for non-traditional exports from Peru in the period January 2004-April 2016, and because they are time series, first tests of unit roots and stationarity are performed on each of the economic series involved in the model of exportable supply, using the contrasts of Dickey-Fuller, Phillips-Perron and KPSS, which turned out to be all, integrated in order 1. To verify the existence of long-term equilibrium relationships between the economic series, two methodologies are used. Relatively recent cointegration: Johansen and Pesaran, Shin and Smith, resulting in the fact that there is effectively cointegration between the economic series and, therefore, the corresponding Error Correction Models are formulated. The results show that the variables Export Price Index and Importer Income (External Income) are determinants to explain the behavior of non-traditional exports from Peru.

Published: March 2023

Despite the acceptance of electric vehicles (EVs) by consumers in developed countries, consumers' intentions towards these smart devices (SD) and the steps that can be taken to expand in this market continue to be investigated in developing countries such as Turkey. In this study, policies and incentives for the purchase of Electric Vehicles in different countries were examined, consumer concerns before the adoption of SDs were evaluated, and then consumer intentions in adopting EVs with models such as reasoned action theory, planned behavior theory, and technology acceptance model were evaluated with bibliometric analysis through conducted studies. Data from 63 publications accessed from Scopus, Web of Science, and DergiPark databases were used in the field mapping process. The results provide insights into increasing the market share of electric vehicles, which are critical in reducing the carbon footprint, by recommending the issues that need to be highlighted to the industry and researchers.
