Authors: Soman Koustubh , Kokate Chinmay , Mohite Atharva , Vispute Ayush , More Omkar , Mundargi Prof. Zarinabegam Kasimali
Published: December 2022

Abstract: The average result of machine learning models is determined using naive 10-fold cross-validation, paired Student's ttest, McNemar's test. The algorithm with the best average performance should outperform those with the worst. But what if the difference in average results is due to a statistical anomaly? A statistical hypothesis test is used to determine whether the mean results of the differences between the three algorithms are real. Using statistical hypothesis testing, this study will show how to compare machine learning algorithms. When choosing a model, the output of several machine learning algorithms or simulation channels is compared. The model that performs best based on your performance measure becomes the final model that can be used to predict new data. With classification and regression prediction models, this can be done using traditional machine learning and deep learning methods. It is difficult to determine whether the difference between the two models is accurate or not.

MUT'AH IN MODERN MUSLIM FAMILY LAW ( Study of Legislation in Syria, Egypt and Indonesia )
Authors: Roslaili Yuni , Mustaqila Safira
Published: December 2022

The reality showed that there are still many injustices against women that can occur anywhere, including in the domestic sector, as well as in Muslim countries. Therefore reform of Muslim family law is seen as necessary because it plays an important role in the protection of women and children and the fulfillment of their rights. Mut’ah is a gift from a husband to his ex- wife after a divorce, including one of the areas reformed in a number of Muslim countries, including in Syria, Egypt and Indonesia. Mut’ah is a gift from a husband to his ex- wife after a divorce is one of the areas reformed in a number of Muslim countries including in Syria, Egypt and Indonesia. The results of the study found that there had been reform of Muslim family law regarding mut’ah in the three countries studied, namely Syria, Egypt and Indonesia. if in traditional literature( fiqh) the right of mut’ah is only obligatory to be given to a divorced wife before had sex and with a dowry that has not been given, but in the three countries studied regardless of whether the wife was divorced before had sex or after had sex and whether the dowry has been determined or not. In addition, in modern Muslim family law there are provisions for the maximum limit of mutah that a husband must give to his wife, such as the standard of living for three years in Syria and two years in Egypt while in fiqh it is determined that the maximum size of mut’ah is not to exceed half the mistsil dowry or the price of a slave.
Konsep Maqāshid SyariaThe Concept of Maqāshid Syariah As-Syāṭiby in the Book Al Muwāfaqāth As-Syāṭiby Dalam Buku Al Muwāfaqāt
Authors: Al Farahidy Khalil
Published: December 2022

As Syātiby is known as the father of Sharia maqāṣid science. This is because of what he wrote in his book Al-Muwāfaqāt. He outlined the concept of Allāh's intent and purpose in implementing the Shari'a. And what he put in his book can be easily understood by his readers, because it is written in neat and orderly divisions. He divided the discussion of objectives into two discussions. The first is Maqāshid Syari' or Allāh in establishing the Shari'a, namely for the good of mankind, and the second is Maqāshid Mukallaf or servant who must be in accordance with and not contradict Maqāṣid Syari'.

THE USE OF MASK AND STRETCHING THE SHAF OF JUSTICE PRAYERS IN THE PANDEMIC PERIOD IN MUI FATWA NUMBER 31 OF 2020: QAWAID FIQHIYYAH PERSPECTIVE
Authors: Puteh Zainuddin , Tanjung Dhiauddin
Published: December 2022

On June 4 2020, the Indonesian Ulema Council (MUI) issued fatwa Number 31 of 2020 concerning "Organization of Friday and Congregational Prayers to Prevent the Transmission of the Covid-19 Outbreak. The fatwa then became the object of scientific study from various perspectives, including regarding prayers using masks and stretching the shaf when praying in congregation. However, no one has yet discussed the relevance and accuracy of the fiqh principles used in fatwas. In fact, the principles of fiqh are one of the normative dimensions of Islamic law which are directly related to practical situations. For this reason, the author feels the need to make aspects of fiqh principles in fatwa as study material - so that the discussion is carried out in a normative (doctrinal) way. After reviewing, the author concludes that the principles used in the fatwa are very relevant and accurate. Therefore, praying using a mask and stretching the shaf is a very appropriate fatwa, because this fulfills the elements of a syar'i intention, namely an endeavor to break the chain of the spread of the life-threatening Covid-19 pandemic
Ontological Roots of the Schism in Economics and the Origins of the Conflicts between Orthodoxy and Heterodoxy
Authors: Akanak Emre
Published: December 2022

This paper discusses the roots of the unending conflicts between Orthodoxy and Heterodoxy in economics, including the paradigms behind the main disagreements. Historically, it is impossible to define any school of economics and thought – in Orthodoxy and Heterodoxy – via homogeneous and monolith terms, concepts, outlines, definitions, and ideas. The most essential and obvious fact of the economy (and the especially central fact of political economy) is the "transformation of economics," including concepts, methodologies, understanding, and even perception(s). Since the early 19th Century, the "concept of economics" has transformed and changed. This process has been advancing on controversial studies based on concrete facts and phenomena in human life (especially inflation, unemployment, growth, wealth, poverty, development, etc.). But just like the methodologies and understanding of the facts, thoughts, and focuses of economic studies, the concepts (and outcomes of these concepts) have also been transforming. Unfortunately, most economists still choose to label themselves via one of the "poles" (Orthodox or Heterodox) and become part of/this polarization. And the economy has much more profound and solid polarization than any other social sciences and natural sciences (math, statistics, physics, chemistry, etc.). Also, this polarization means more than just methodologic differentiation. It also includes biases and, most of the time, ideologic backgrounds. This fact makes "the schism" much deep, unique and vital, especially in critical periods (such as like financial crisis in 2007, Covid19 in 2019, and many others). Also, unlike other social sciences, economics is directly related to daily life (and political dilemmas).
The Problem of Meaningful Differentiation of Fyodor Dostoevsky’s Rough Sketches for Different Work
Authors:   Institute of Russian Literature (Pushkin House) of the Russian Academy of Sciences, Tarasova Natalia A. , Panyukova Tatiana V. ,   Petrozavodsk State University
Published: December 2022

The paper deals with issues of textual research and publication of Fyodor Dostoevsky’s draft manuscripts. The authors of the article focus on the problem of contextual analysis of handwritten materials and meaningful differentiation of entries related to different creative ideas of the writer, which at the draft stage is often a significant difficulty for researchers. As a result of the critical analysis proposed in the article, inaccuracies of reproduction and omissions in scientific publications of Fyodor Dostoevsky’s drafts were found. The textual and real comments on the studied material were supplemented. The analysis of this problem remains relevant due to the complex composition of the manuscript heritage of Fyodor Dostoevsky. The writer’s workbooks include a considerable number of scattered draft notes, the boundaries of which and the thematic affiliation to a particular idea are not always clear. In addition, scholarly reflection on the content of Fyodor Dostoevsky’s draft notes is particularly relevant in the context of the academic preparation of the complete collections of the writer’s works.
People and Puppets and Puppet-People in the Play Uncle’s Dream by the Irkutsk Puppet Theatre “Aistenok”
Authors:   Irkutsk State University, Yuryeva Olga Yu.
Published: December 2022

The review examines the performance of the Irkutsk puppet theatre “Aistenok” Uncle’s Dream, staged on the occasion of the writer’s 200th anniversary. The author analyzes the expressive means that allowed the director and actors to examine in depth Dostoevsky’s idea, vividly and remarkably represent the characters, offer an original interpretation that does not destroy the author’s concept, leveraging the dramatic intentions implied in the novella, thanks to the synthesis of acting and puppet theatre. The puppet materializes and visualizes a person’s vices, masks, secret aspirations, and desires. The possibilities to express these elements that the puppet gives to the artist are indeed limitless. Therefore, the object of the stage performance is not the plot nor single characters, but Dostoevsky’s philosophy of life. The performance by the Irkutsk puppet theatre incorporates the experience of theatre during 20th and 21st centuries, modernist and postmodernist trends, transforming the puppet show into a truly theatrical action with deep philosophical content. This innovative reading became possible exclusively thanks to the synthetic actor-puppet nature of the performance.

The Premonition of Death as a Test of Faith for the Characters of the Novel The Idiot
Authors:   Orthodox Gymnasium “Cyril and Methodius, Equal to the Apostles”, Flegentova Tatiana N.
Published: December 2022

For the Christian understanding, life is a period of time presenting trials and leading to eternity. Any instant of life is a reminder of death and at the same time it contains the potential for transfiguration. From this point of view, the “last minute” of life becomes decisive. In the Gospel, the last words of one of the villains crucified with Christ opened the way for him to forgiveness. The heroes of the novel The Idiot are immersed in “last minute” situations through the processes of telling, listening to stories about death penalty. Prince Myshkin, Nastasya Filippovna, Ippolit: each of them “feels a knife over his head.” Time turns into a continuous torture: they either bring the end closer, or seek to escape from it, becoming prisoners of the present. Ippolit, for instance, seeks to fix all the events of life into a calendar, however, he constantly makes mistakes, setting the dates of the phenomena of reality that have occurred incorrectly. The true meaning of any historical moment is the possibility of decision in a demanding situation, to establish one’s position regarding good and evil. The freedom granted to a person is a blessing and infinite mercy, one of the manifestations of which is the sympathy for others. In his “Explanation,” Ippolit tells two stories, combining them in time: “Around the middle of March.” The hero of the first one is Ivan Fomich Surikov, the “noble” eternal debtor; in the second we see a doctor who came to St. Petersburg “to explain himself,” whose second child had just been born. The sudden appearance of Ippolit in their family can be described by the simple formula “sent by God,” as he meets the circumstances and helps the young family. The maneuvering between good and evil manifests the duality of his personality. The foreboding of death turns out to be a test of faith, as it reveals the true value of a person’s life and his place in the space of time.

Published: December 2022

We explore model performance for the Alfvén Wave Solar atmosphere Model
(AWSoM) with near-real-time (NRT) synoptic maps of the photospheric
vector magnetic field. These maps, produced by assimilating data from
the Helioseismic Magnetic Imager (HMI) onboard the Solar Dynamics
Observatory (SDO), use a different method developed at the National
Solar Observatory (NSO) to provide a near contemporaneous source of data
to drive numerical models. Here, we apply these NSO-HMI-NRT maps to
simulate three Carrington rotations (CRs): 2107-2108 (centered on
2011/03/07 20:12 CME event), 2123 (integer CR) and 2218-2219 (centered
on 2019/07/2 solar eclipse), which together cover a wide range of
activity level for solar cycle 24. We show simulation results, which
reproduce both extreme ultraviolet emission (EUV) from the low corona
while simultaneously matching in situ observations at 1 au as well as
quantify the total unsigned open magnetic flux from these maps.
Is ecology different when studied with citizen scientists? A bibliometric analysis
Authors: Castagneyrol Bastien , Bedessem Baptiste , Julliard Romain
Published: December 2022

Ecology is broad and relies on several complementary approaches to study
the mechanisms driving the distribution and abundance of organisms and
their interactions. One of them is citizen science, the co-production of
scientific data and knowledge by non-professional scientists, in
collaboration with or under the direction of professional scientists.
Citizen science has bloomed in the scientific literature over the last
decade and is being incrasingly popular. We used a bibliometric analysis
to study whether associating the public to ecological research changes
the making of ecology and the nature of questions it asks. We analysed
keywords and abstracts of 41,105 articles published the last ten years,
disentangling CitSci articles (those explicitly referring to citizen
science) and non-CitSci articles. Keyword co-occurrence and thematic map
analyses revealed that CitSci articles primarily focused on biodiversity
and climate change in a more descriptive way than non-CitSci articles
which were more likely to address theoretical questions in ecology.
Roughly, citizen science in ecology addressed patterns, whereas non
participatory research dug further into mechanisms. Biodiversity also
appeared as a more central theme in the CitSci corpus, where it was more
systematically associated with other keywords. Our study indicates that
should the surge of citizen science approaches in ecological scientific
literature have change the type of ecological inquiry, this thematic
change is marginal. Still, we provide evidence that specific research
questions individualized from ecological CitSci thus supporting the view
that citizen science is becoming an independent field of investigation,
and not only a peculiar methodological approach to ecological research.

Aggregator pricing method based on two-stage charging station allocation for electric vehicles
Authors: LI Yonggang , Lin Hui , Zhou Yichen , Zheng Haoyang , Bian Zhaoyuan , Yue Ziyi , Yang Yang , Zhen Xinghao
Published: December 2022

With the proposal of the carbon peaking and carbon neutrality goals, the
number of electric vehicles is increasing day by day. Besides, the
insufficient number of charging piles leads to the increase of the
queuing time of electric vehicles, the pricing of aggregators and other
issues becoming increasingly prominent. To solve the above problems, the
aggregator pricing method of two-stage charging station allocation for
electric vehicles is proposed. First, the contract signing mode between
aggregators and electric vehicles is divided into three categories:
complete dispatching, rolling reward and punishment mechanism
dispatching, and free dispatching. Considering the impact of external
factors on the energy consumption of electric vehicles, a road network
model is established. Then, the improved A-star algorithm is used to
solve the shortest path, in which the time factor is introduced into the
evaluation function of A-star algorithm. At the same time, the
evaluation function is improved according to traffic energy consumption,
uninterrupted driving time, traffic light waiting time and other
factors. The aggregator obtains the attraction of the charging station
to the electric vehicle based on the charging and discharging demand of
the electric vehicle and the Coulomb’s law, and then establishes the
grid aggregator electric vehicle supply chain, and conducts reasonable
pricing and charging station allocation in two stages. Finally, an
example shows that this scheme can significantly improve the peak
shaving efficiency, improve the profits of aggregators, and reduce the
queuing time and traffic energy consumption of electric vehicles in
terms of the distribution of electric vehicle charging stations and the
pricing of aggregators.
Extreme Compound and Seesaw Hydrometeorological Events in New Zealand: An Initial Assessment
Authors: Bennet Morgan James , Kingston Daniel G , Cullen Nicolas J.
Published: December 2022

Attention is increasingly being turned towards an investigation of
extreme hydrometeorological events within the context of land-atmosphere
coupling in the wider hydrological cycle, particularly with respect to
the identification of compound and seesaw events. To examine these
events, accurate soil moisture data are essential. Here, soil moisture
from three reanalysis products (ERA5-Land, BARRA and ERA5) are compared
to station observations from 12 sites across New Zealand for an average
timespan of 18 years. Soil moisture data from all three reanalyses were
subsequently used to investigate land-atmosphere coupling with gridded
(observational) precipitation and temperature. Finally, compound
(co-occurrence of hot and dry) and seesaw (transitions from dry to wet)
periods were identified and examined. No best performing reanalysis
dataset for soil moisture is evident (min r = 0.78, max r = 0.80). All
datasets successfully capture the seasonal and residual component of
soil moisture, but not the observed soil moisture trends at each
location. Strong coupling between soil moisture and temperature occurs
across the predominately energy-limited regions of the lower North
Island and entire South Island. Consequently, these regions reveal a
high frequency of compound period occurrence and potential shifts in
land states to a water limited phase during compound months. A series of
seesaw events are also detected for the first time in New Zealand
(terminating an average of 17% of droughts), with particularly high
frequency of seesaw event occurrence detected in previously identified
areas of atmospheric river (AR) activity, indicating the likely wider
significance of ARs for drought termination.
First onset of unrest captured geodetically at Socompa Volcano, Northern Chile

Published: December 2022

We report the first detection of unrest at Socompa, Northern Chile, a
stratovolcano which has recorded no eruptions since
~7,200 years ago. We measure deformation at and around
Socompa using Interferometric Synthetic Aperture Radar (InSAR)
observations between Jan 2018 and Oct 2021. We find that, whilst
initially inactive, Socompa shows a steady uplift (17.5 mm/yr) from Dec
2019, independently recorded by near-field continuous Global Positioning
System (GPS) data. The data can be fit with pressure increase in an
ellipsoidal source region stretching from 1.9 to 9.5 km, with a volume
change rate of ~5.8×106 m3/yr. Our observations of the
onset of uplift preclude the possibility that a nearby Mw 6.8 deep
intraslab earthquake on 3rd June 2020 triggered the unrest. The
deformation signal we detect indicates the initiation of unrest at
Socompa, after at least two decades without measurable deformation, and
many thousands of years without volcanic activity.
Multi-Scale Flood Simulations Under Climate Change Scenarios
Authors: Markhali Siavash Pouryousefi , Poulin Annie , Boucher Marie-Amélie
Published: December 2022

The present study focuses on quantifying the impact of the choice of
spatio-temporal resolution and hydrology models on the projection of
extreme flow and their link to the catchment size. We use two
process-based distributed hydrology models forced with a large-ensemble
regional climate model (50-member ClimEx dataset) over the 1990-2100
period at different spatio-temporal scales. The extreme summer-fall flow
corresponding with each spatio-temporal resolution was extracted by
pooling the members together and computing the empirical cumulative
distribution function. The results show that by refining the time-step
from daily to sub-daily, the summer-fall extreme flow projected over the
future period exceeds that of the reference period for the small but not
large catchments. By increasing the catchment size, the hydrology
model’s contribution to the variability of extreme flow increases.
Moreover, the choice of spatial resolution affects the extreme flow’s
trend in terms of magnitude, significance, and direction. But no pattern
regarding the catchment size and spatial discretization variations
exists.
Regional Impact of Snow-Darkening on Snow Pack and the Atmosphere During a Severe Saharan Dust Deposition Event in Eurasia
Authors: Rohde Anika , Vogel Heike , Hoshyaripour Gholam Ali , Kottmeier Christoph , Vogel Bernhard
Published: December 2022

Light-absorbing impurities such as mineral dust can play a major role in
reducing the albedo of snow surfaces. Particularly in spring, deposited
dust particles lead to increased snow melt and trigger further feedbacks
at the land surface and in the atmosphere. Quantifying the extent of
dust-induced variations is difficult due to the high variability in the
spatial distribution of mineral dust and snow. We present an extension
of a fully coupled atmospheric and land surface model system to address
the impact of mineral dust on the snow albedo across Eurasia. We
evaluated the short-term effects of Saharan dust in a case study. To
obtain robust results, we performed an ensemble simulation followed by
statistical analysis. Mountainous regions showed a strong impact of dust
deposition on snow depth. We found a mean significant reduction of -1.4
cm in the Caucasus Mountains after one week. However, areas with flat
terrain near the snow line also showed strong effects despite lower dust
concentrations. Here, the feedback to dust deposition was more
pronounced as increase in surface temperature and air temperature. In
the region surrounding the snow line, we found an average significant
surface warming of 0.9 K after one week. This study shows that the
impact of mineral dust deposition depends on several factors. Primarily,
these are altitude, slope, snow depth, and snow cover fraction.
Especially in complex terrain, it is therefore necessary to use fully
coupled models to investigate the effects of mineral dust on snow pack
and the atmosphere.
Mantle source and melting processes beneath Iceland’s Flank and Rift Zones: Forward Modelling of Heterogeneous Mantle Melting
Authors: Waters Emma Christina , Shorttle Oliver , Halldórsson Sæmundur Ari , Kobayashi Katsura , Neave David , Burgess Ray , Hartley Margaret E
Published: December 2022

The Icelandic mantle contains a range of lithologies associated with the
depleted upper mantle, a mantle plume, and recycled oceanic lithosphere
but the precise nature of depleted and enriched components in the mantle
and their relative contributions to melt production remain poorly
constrained. In this study, we collect new olivine- and
plagioclase-hosted melt inclusion data and compile this with existing
literature data to investigate the relative contributions from different
mantle lithologies to basaltic magmas erupted in Icelandic flank zones
and neovolcanic zones by modelling the melting of a heterogeneous mantle
and subsequent mixing of derived melts. We find that observed melt
inclusion compositions from off-axis flank zones are best explained as
homogenized mixtures of pyroxenite- and lherzolite-derived melts
produced at depths around 80-93 km, by which point lherzolite has only
experienced a low degree of melting whereas the pyroxenite lithology has
melted extensively. These melts represent the onset of channelization in
the mantle and are transported rapidly to the surface without input from
shallower melts. Melt compositions from the on-axis neovolcanic zones
and off-axis Öræfajökull, are produced by mixing this deep melt
component with higher degree lherzolite melts produced at shallower
depths, between 57-93 km. Proportions of shallow lherzolite-derived
melts and deep homogenized melt vary, but the lowest contribution from
the deep homogenized melt is seen in the Northern Volcanic Zone.
Ourresults support a model whereby deep melts mix until melt
channelization starts in the mantle, after which binary mixing between
the homogenized deep melt and shallower fractional melts occurs.
Experimental evaluation of predicted undrained pore pressure generation as function of stress path and orientation in the Draupne shale
Authors: Soldal Magnus , Choi Jung Chan , Skurtveit Elin
Published: December 2022

Injection or production of fluids from subsurface reservoirs lead to
stress changes affecting both reservoir and surrounding rocks. For
low-permeable caprocks overlying such reservoirs, the movement of pore
fluids to or from the formation is restricted and the immediate and
short-term response to changes in the stress field will be undrained.
Consequently, stress changes transfer partly into pore pressure changes.
The aim of the current study is to investigate theoretical means of
forecasting the undrained pore pressure generation in the Draupne
Formation shale and to compare predictions with experimental results.
Predictions are based on measurements from a single undrained triaxial
test on a sample with known orientation, and a combination of Skempton’s
classical formulation and anisotropic poroelastic theory. The predicted
pore pressures are compared to measured pore pressures from a series of
triaxial tests on samples with various orientations exposed to different
total stress paths. First, it is confirmed that the normalized undrained
pore pressure measured is linearly connected to the total stress path.
Then it is demonstrated that a tensorial pore pressure parameter can be
used to accurately predict the influence of stress orientation on
generated pore pressure. Lastly, it is experimentally confirmed that the
two predictions can be combined to predict the pore pressure arising
from stress changes along any compressional stress path and orientation.
The observations herein may contribute significantly to the
understanding of induced pore pressure in low-permeable materials and
provide valuable input to geomechanical modeling of various field
operations.
A Snapshot of Turbulence in the Northeastern Strait of Magellan

Published: December 2022

First-ever measurements of the turbulent kinetic energy (TKE)
dissipation rate in the northeastern Strait of Magellan (Segunda
Angostura region) taken in March 2019 are reported here. At the time of
microstructure measurements, the magnitude of the reversing tidal
current ranged between 0.8 and 1.2 ms-1. The probability distribution of
the TKE dissipation rate in the water interior above the bottom boundary
layer was lognormal with a high median value εmed =1.2x10-6 Wkg-1.
Strong vertical shear, (1-2)x10-2 s-1 in the weakly stratified water
interior ensued a sub-critical gradient Richardson number,
Ri<10-1-10-2. In the bottom boundary layer (BBL), the vertical
shear and the TKE dissipation rate both decreased exponentially with the
distance from the seafloor ζ, leading to a turbulent regime with the
eddy viscosity KM~10-3 m2/s, which varied with the time
and location, while being independent of the vertical coordinate in the
upper part of BBL (for ζ>~2 meters above
the bottom).

Authors: Erdogdu Yüksel
Published: December 2022

The aim of this study was to develop “Teachers’ Views on Mixed and Single-gender Education Scale”. The study group consisted of 718 teachers in 18 different schools who volunteered to participate in the study in Küçükçekmece District of İstanbul. Both Exploratory and Confirmatory Factor Analysis were carried out for the validity of the scale. With Exploratory Factor Analysis, it was found that the scale consisted of two factors (positive views on single-gender education and positive views on mixed-gender education) and 18 items and the scale explained 63% of the total variance. When the fit index values of the scale were examined, it was found that the model had a good fit [RMSEA=,05, SRMR=,05, CFI=0.98, GFI=0.93, AGFI=,91, NFI=,95 and IFI=0.98]. In order to calculate the discriminative values of the scale items, mean scores of upper and lower groups were examined with t-test and it was found that all of the items were discriminative. Cronbach Alpha values calculated for the scale reliability were found to vary between, 81 and ,89.
Examination of Parents' Selection of Children Books
Authors: Yazıcı Elçin
Published: December 2022

The research was conducted to determine whether the education and income status of the parents made a difference in the selection of books. The study group of the research consisted of 151 parents who had children aged 3-6 years. These children attended independent public preschools in the city centre of Istanbul, which were selected by a random sampling method. Data were collected in two steps. First, a “General Information Form” was delivered to collect generic information on the parents. Then, Saçkesen’s (2008) “Children’s Book Selection Criteria Scale” was utilised to determine the consideration of parents for choosing a book for their children. The research is a causal-comparative study that aims to determine the causes or consequences of differences between groups. A Two-Way ANOVA was performed in the 3x3 model, as there were three categorical independent variables belonging to income level, three categorical independent variables belonging to education level, and a dependent variable in the continuous variable structure in the study. The findings indicate no significant difference between the book choice criteria of parents according to the income level when the education levels of the parents are not taken into consideration. However, when the income levels are not taken into consideration, a significant difference was found between the education level scores of parents for their book selection criteria. After a significant interaction between the income and education levels was found, simple effect analyses for the subgroups reveal significant differences between the secondary school-high school graduation levels of the parents in the low-income group and the secondary school-university graduation levels of the parents in the middle-income group. Focusing on parents with lower education and income levels can be a good starting point to increase parents' awareness of book selection.
One-way ticket from unemployment to entrepreneurship? Evaluation of allowance for self-employment in least developed regions

Published: December 2022

Entrepreneurship support for the unemployed is one of the most common entrepreneurial policy tools for small start-ups. Usually, this tool is aimed at simultaneously promoting entrepreneurship as well as reducing unemployment. The aim of this paper is to examine in detail the effects of such an instrument in one of the least developed regions of the European Union (EU). At the same time, however, this region has been very effective in reducing the unemployment rate at the time of the research. The paper focuses, in particular, on entrepreneurship survival after support and compares it with maintenance of employment, in general. Our results, based on probit and bivariate probit regression, suggest that gender, age, economic development of the region and the amount of support are among the most important factors affecting the survival of start-ups after support. The differences between more developed and less-developed sub-regions are particularly pronounced for certain socio-economic groups such as women with tertiary education or married couples. We have also illustrated some aspects that artificially prolong the survival of supported entrepreneurship, such as the use of entrepreneurship as a substitute for dependent or part-time work.

For tobacco strips used in cigarette production, the stem content is an important quality index to assess the impurity level of the cut leaves. The presented work developed a nondestructive detection method of stems in cut leaf agricultural products by the low energy X-ray imaging. The algorithm of stem image processing and weight calculation principle was established, and then a machine vision system with X-ray imaging and image analysis was set up to verify the quantitative detection method. The results showed that the relative error of the detection method ranged from −3.64% to 2.76%. The determination of stems with a different morphology, such as the thick stem, were also realized based on the image analysis. The accuracy of determining thick stem and long stem was 94.67% and 99.33%, respectively. The developed method is superior to the current ISO detection method of tobacco stem in leaves under the same testing conditions in terms of accuracy and efficiency, which could be applied as an effective online detection method to monitor the quality of processed leaf for cigarette production.
