Authors: Lin Chien-Heng , Chen Chieh-Ho , Hong Syuan-Yu , Chou I-Ching , Liang Shinn-Jye , Hang Liang-Wen
Published: January 2021

In this study, we collected and analyzed PSG data to investigate that
value of polysomnography (PSG) in diagnosing sleep problems in children.
The results of PSG studies of children (< 18 years old) with
sleep problems conducted from April 2015 to May 2017 at a children’s
hospital in Taiwan were collected and analyzed retrospectively. Data for
310 patients (209 males and 101 females) who underwent PSG were
collected. The final diagnoses were as follows: obstructive sleep apnea
in 159 (51.3%), snoring in 81 (26.4%), limb movement sleep disorder in
25 (8.1%), hypersomnias in 12 (3.9%), central apnea in 8 (2.9%),
enuresis in 7 (2.3%), bruxism in 5 (1.6%), sleep terrors in 5 (1.6%),
narcolepsy in 3 (1.0%), sleep seizures in 3 (1.0%), sleep walking in 1
(0.3%), and insomnia in 1 (0.3%). PSG may help detect significant
sleep-related problems in children and is useful for making therapeutic
decisions regarding children. Obstructive sleep apnea syndrome (OSAS)
was the primarily sleep problem for most of the children (51.3%);
however, only 7.4% of them underwent surgery for OSAS, even though
those with OSAS underwent surgery without undergoing PSG. We therefore
suggest that children with sleep problems should undergo PSG.
Toward A More Precise - and Accurate - View of Eco-Evolution
Authors: Bassar Ronald , Coulson Tim , Travis Joseph , Reznick David
Published: January 2021

Over the past fifteen years, the number of papers focused on “eco-evo
dynamics” has increased exponentially (Figure 1). This pattern suggests
the rapid growth of a new, integrative discipline. We argue that this
overstates the case. First, the terms “eco-evo dynamics” and “eco-evo
interactions” are used too imprecisely. As a result, many studies that
claim to describe eco-evo dynamics are actually describing basic
ecological or evolutionary processes. Second, these terms are often used
as if the study of how ecological and evolutionary processes are
intertwined is novel when, in fact, it is not. The result is confusion
over what the term “eco-evolution” and its derivatives describe, a
loss of appreciation for the history of genuine eco-evolutionary
studies, and a loss of appreciation for the novelty associated with the
original rise of the term. We advocate a more precise definition of
eco-evolution that is more useful in our effort to understand and
characterize the diversity of ecological and evolutionary processes and
that focuses attention on the subset of those processes that offer novel
results.
Poor diet quality and adverse eating behaviours in young survivors of childhood cancer
Authors: Fleming Catharine , Murphy-Alford Alexia , Cohen Jennifer , Fleming Mike , Wakefield Claire , Naumann Fiona
Published: January 2021

Background The long-term impact of childhood cancer treatment on dietary
intake is likely to be complex and the length of time dietary behaviours
are affected after childhood cancer treatment is unknown. Aim The aim of
this study was to determine the diet quality in childhood cancer
survivors recently off treatment and identify possible contributing
factors that may affect diet quality in this population. Methods
Participants were 65 parents and/or carers of childhood cancer survivors
(CCS) (aged 2-18 years), recently off treatment and 81 age-matched
controls. Methods Participants completed two self-administered dietary
intake and eating behaviour questionnaires. Study data was explored to
determine between group differences, bivariate analysis using Spearman’s
correlations was used to determine the relationship between diet quality
and identified variables, and hierarchical cluster analysis was
completed to characterise specific variables into clusters. Results CCS
had a significantly poorer diet quality score than the age-matched
controls (t=-2.226, p=0.028). Childhood cancer survivors had
significantly higher parent-reported rates of ‘picky eating’ behaviour
than the control group (t=0.106 p=0.044). Factors such as picky eating,
emotional overeating and Body Mass Index z-score appeared to drive diet
quality in survivors. Conclusions A CCS with picky eating behaviours
could avoid complete food groups, have strong food preferences/aversions
and over- consume high energy foods to maintain their energy intake,
possibly affecting diet quality. The outcomes highlighted the need for a
tailored intervention aimed at improving healthy eating behaviours in
CCS after treatment for cancer.

Authors: Xu Jian , Lan Xiao-Bing , Xia Lin-Jian , Yang Yi , Cao Gao
Published: January 2021

The purpose of this research was to reduce the amount of noble metal palladium catalyst and improve the catalytic performance in the Suzuki?Miyaura cross-coupling reaction, which is the key step in the synthesis of Boscalid. Taking o-bromonitrobenzene and p-chlorophenylboronic acid as raw materials, three kinds of Pd-PEPPSI-IPr catalysts were synthesized and employed in the Suzuki reaction, and then the biaryl product was subjected to reduction and condensation reaction to give Boscalid. Under the optimal reaction conditions, the result showed that the catalytic system exhibits highest catalytic efficiency under aerobic conditions, giving the 2-(4-chlorophenyl)nitrobenzene in over 99 % yield. Moreover, the Pd-PEPPSI-IPrDtBu-An catalyst was minimized to 0.01 mol%. The synthesis process was mild, the post-treatment was simple, and the production cost was reduced, which makes it suitable for industrial production.

Evolutionary and functional characterization of oxidative stress proteins in dendroctonus ponderosae hopkins (curculionidae: scolytinae)
Authors:   , Spooner Luke
Published: January 2021

Understanding the mountain pine beetle detoxification systems is vital for predicting its continued spread into the novel jack pine host. Phylogenetic analyses were conducted for mountain pine beetle catalase, glutathione peroxidase, superoxide dismutase, and peroxiredoxin. These proteins were generally conserved, but there were differences in some key functional motifs. Specifically, a peroxiredoxin (DPPrx1) contained a unique combination of hyperoxidation motifs. DPPrx1 and a superoxide dismutase (DPSOD1) were selected for further functional analyses and demonstrated higher reactivity when compared to other SOD and Prx proteins. Also, DPPrx1 experiences hyperoxidation at a lower H2O2 concentration (~0.06 mM) than human peroxiredoxin (~0.12 mM). In other systems, hyperoxidized peroxiredoxin does act as a signal molecule for the expression of other oxidative stress proteins. Therefore, due to its relatively high reactivity and potential role as a cellular signal, DPPrx1 could serve as a future pest management target.
New trends in project portfolio management
Authors: Fiala Petr
Published: January 2021

The use of project portfolio management is increasingly becoming a tool for promoting the strategy of the organization. Using sophisticated quantitative tools becomes a significant competitive advantage for project portfolio management. Project portfolio management is a dynamic multi-criteria decision-making problem under risk. The paper presents new approaches for analyzing the problem. A dynamic version of the Analytic Network Process (ANP) captures the network, multicriteria and dynamic structure of the problem. Multicriteria decision trees analyze risk of project portfolios. Possible projects are characterized by sets of inputs and outputs, where inputs are resources for project realization and outputs measure multiple criteria of goals of the organization. The Data Envelopment Analysis (DEA) is an appropriate approach to select efficient project portfolios.
Work productivity in the sector of knowledge intensive services in relation to work productivity in the manufacturing industry
Authors: Vrbka Jaromír , Rowland Zuzana , Frýd Lukáš
Published: January 2021

The manufacturing industry represents the most important part of gross output in the Czech Republic. In the long run, it is necessary for the Czech industry to be competitive. At the same time, it can be assumed that foreign pressure on the Czech manufacturing industry will at least partially transform into pressure on professional and scientific activities. Science and research thus play a key role. The aim of the article is to analyse the impact of work efficiency in the branch of professional, scientific, technical, administrative and support service activities (i.e. sections M and N of the CZ NACE classification of economic activities) on the manufacturing industry (section C). Productivity is measured as gross value added to the labor. The quarterly data of the Czech Statistical Office for the period 1995-2020 are used for the analysis. Time series are processed using a Census X12 filter; all variables are tested using the ADF test in two variants for the presence of a unit root. The testing of the long-term relationship is conducted by means of the Johansen test. The results show that both productivity delays in sector C and sectors M and N have a statistically significant impact on productivity in sector C. However, a positive productivity shock in sector C has a negative impact on current productivity and, conversely, a positive shock in productivity in branch M + N in t-1 is positively reflected in branch C at time t.

Anomalies of the control principle as part of the consolidated financial reporting concept
Authors: KOLCHUGIN Sergei V.
Published: January 2021

Subject. The article discusses the impact of the control principle on the existing consolidated financial reporting concept.
Objectives. I evaluate possible alterations in the consolidation methodology as a result of the anomaly of the control principle.
Methods. The study is based on the method of analogy for scientific hypothesizing. The study methodologically relies upon Thomas Kuhn's paradigm shift theory and the impact of anomalies on methodological principles of normal science. The study combines the analysis and synthesis, induction and deduction, and the method of comparison when analyzing the existing control criteria and identifying anomalies of the control principles as part of the consolidated financial reporting concept, and examining how the anomaly influences the consolidation methodology.
Results. I discovered that the control principle in the consolidated financial reporting concept influences the consolidation methodology. I suggest using my own methodological approach to preparing consolidated financial statements in case of the non-equity control the parent company holds over its subsidiary.
Conclusions and Relevance. The control principle in the consolidated financial reporting concept has not been formalized, thus causing anomalies affecting methodological principles of consolidated financial reporting. The non-equity control of the parent company over its subsidiary is a case in point. This control induces unavoidable changes in the consolidation methodology. The findings can be used to prepare consolidated financial statements in case of the non-equity control of the parent company over its subsidiary.

Authors: LISOVSKAYA Irina A. , Natal'ya G. TRAPEZNIKOVA Natal'ya G.
Published: January 2021

Subject. As stipulated in Federal Accounting Standard 5/2019 – Inventories, which is to enter into effect in 2021 and apply to respective financial statements, inventories are now accounted for in a different way. Federal Accounting Standard 5/2019 introduces new clauses and provides for some requirements concerning the use of discounted estimates and recognition of impairment of inventories. Therefore, we study the clauses and display how they should be implemented. Objectives. We herein analyze clauses of Federal Accounting Standard 5/2019 – Inventories, which may be construed ambiguously. We also provide our suggestions on the reasonable use of novelties introduced by the standard. Methods. The study is based on the systems analysis and logic generalization of legislative and regulatory documents and special literature on the respective issues. Results. Our examples demonstrate how the acquisition of inventories should be recognized in case of the long-term deferral of payment and valuation of inventories upon their recognition. Conclusions and Relevance. The adoption of Federal Accounting Standard 5/2019 dictates for amending corporate accounting policies and preliminary work to revisit some aspects of inventories accounting. Hence, it is reasonable to give methodological clarifications on some complicated practical issues. The findings are intended for scientific and practical activities, training of experts in accounting and financial management. They also may help make suggestions on the improvement of the Russian accounting technique for the convergence with the contemporary international practice.

Subject. The article discusses the specifics of migration processes in the border region of Russia and Kazakhstan.
Objectives. I analyze practical aspects of migration in the border region of Russia and Kazakhstan and review what can be done to maintain the socio-economic stability and retain human capital in border regions of the Russian Federation.
Methods. The study is based on methods of analysis, systematization, comparison and matching.
Results. I point out the specifics of the Russian constituent entities that lie on the border with Kazakhstan. I indicate distinctions of outbound and inbound migration processes in the analyzable areas. The article presents the analysis of the migration growth in the Russian regions bordering on the Kazakh areas, monitoring of incoming and outgoing migrants along directions of their movement. The article illustrates the composition of migrants who arrive in and leave the Russian regions bordering on Kazakhstan. The article enlists what can be done to maintain the socio-economic stability and retain human capital in the border regions of respective constituent entities of the Russian Federation.
Conclusions and Relevance. Most regions bordering on Kazakhstan see a negative migration growth and considerable numbers of cross-border migrants. There are also significant cross-regional movements in the regions. To maintain the socio-economic stability in the border regions as part of the national policy, the national structure of migration should be taken into consideration. The government should urgently take efforts to set up a versatile model that would help immigrants undergo the social adaptation and integrate into the Russian society.

Przedsiębiorczość społeczna – ujęcie procesowe
Authors: Pacut Agnieszka
Published: January 2021

Jednym z podstawowych problemów badawczych dotyczących przedsiębiorczości społecznej jest brak jej jednoznacznej definicji. Problem ten jest dostrzegalny także w Polsce, gdzie pojęcie to wyjaśniane jest w odniesieniu do koncepcji gospodarki społecznej i trzeciego sektora lub traktowane jest jako metafora działań innowacyjnych podejmowanych przez różne grupy i podmioty. Celem niniejszego artykułu jest wyjaśnienie znaczenia terminu „przedsiębiorczość społeczna” z wykorzystaniem podejścia procesowego. Do realizacji tego celu wykorzystano metodę analizy i syntezy literatury przedmiotu. W wyniku analizy stwierdzono, iż procesowe ujęcie przedsiębiorczości społecznej jest użyteczną perspektywą analityczną dla rozumienia sedna działalności łączącej cele społeczne z metodami rynkowymi, jak również poznania przebiegu procesu przedsiębiorczego na poziomie mikro. Jednocześnie sformułowano wniosek o konieczności popularyzacji w Polsce badań o charakterze empirycznym i teoretycznym z wykorzystaniem podejścia procesowego, zwłaszcza w kontekście braku prawnej definicji przedsiębiorstwa społecznego oraz wstępnych ustaleń w tym zakresie.
