COGNITIVE AND NON-COGNITIVE FACTORS RELATED TO STUDENTS’ STATISTICS ACHIEVEMENT
Authors: CHIESI FRANCESCA , PRIMI CATERINA
Published: September 2021

The aim of this study was to investigate students’ achievement in introductory statistics courses taking into account the relationships between cognitive and non-cognitive factors. It was hypothesised that achievement was related to background in mathematics (a cognitive variable), as well as to attitudes toward statistics and anxiety (non-cognitive variables). Students were presented with measures assessing their attitudes, mathematical competence, and anxiety toward courses and examinations at the beginning and at the end of their statistics course. Achievement was assessed by tasks assigned during the course, as well as by students’ final grades and the number of exam failures. The results reveal the reationships between cognitive and non-cognitive factors, their changes during the course, and how both interact in predicting achievement.

Comparison of Lower Extremity Kinematics during the Overhead Deep Squat by Functional Movement Screen Score
Authors: Heredia Caitlyn , Lockie Robert G. , Lynn Scott K. , Pamukoff Derek N.
Published: September 2021

It is unclear if the Functional Movement Screen (FMS) scoring criteria identify kinematics that have been associated with lower extremity injury risk. The purpose was to compare lower extremity kinematics of the overhead deep squat (OHDS) during the FMS between individuals who were grouped on FMS scoring. Forty-five adults who were free of injury and without knowledge of the FMS or its scoring criteria (males = 19, females = 26; height = 1.68 0.08 m; mass = 70.7 7 13.0 kg). Three-dimensional lower extremity kinematics during an OHDS were measured using a motion capture system. One-way MANOVA was used to compare kinematic outcomes (peak hip flexion angle, hip adduction angle, knee flexion angle, knee abduction angle, knee internal rotation angle, and ankle dorsiflexion angle) between FMS groups. Those who scored a 3 had greater peak hip flexion angle (F2,42 = 8.75; p = 0.001), knee flexion angle (F2,42 = 13.53; p = 0.001), knee internal rotation angle (F2,42 = 12.91; p = 0.001), and dorsiflexion angle (F2,42 = 9.00; p = 0.001) compared to those who scored a 2 or a 1. However, no differences were found in any outcome between those who scored a 2 and those who scored a 1, or in frontal plane hip or knee kinematics. FMS scoring for the OHDS identified differences in squat depth, which was characterized by larger peak hip, knee, and dorsi- flexion angles in those who scored a 3 compared with those who scored 2 or 1. However, no differences were found between those who scored a 2 or 1, and caution is recommended when interpreting these scores. Despite a different FMS score, few differences were observed in frontal or transverse plane hip and knee kinematics, and other tasks may be needed to assess frontal plane kinematics.

The Frequency-Dependence of Pre- and Postganglionic Nerve Stimulation of Pig and Rat Bladder
Authors: Kitney Darryl , Crook John , Chakrabarty Basu , Kanai Anthony , Vahabi Bahareh , Lovick Thelma , Fry Christopher
Published: September 2021

Purpose: The urinary bladder generates phasic contractions via action potentials generated in pre- and then postganglionic neurons. Whilst the frequency-dependence of postganglionic neurons to generate contractions has been quantified, the dynamic range of preganglionic neurons is less clear and if intramural ganglia exert frequency-dependent modulation of transmission between pre- and postganglionic neurons. The phosphodiesterase type 5 inhibitor sildenafil reduces neurotransmitter release from postganglionic fibres to detrusor smooth muscle and an additional question was if there was also a preganglionic action. This study aimed to compare the frequency range of bladder contractile activation by pre- and postganglionic stimulation in pig and rat bladders and if sildenafil exerted additional preganglionic actions.Methods: An arterially-perfused ex vivo pig bladder preparation was used for preganglionic (pelvic nerve) and mixed pre-and postganglionic (direct bladder wall) stimulation at 36°C and postganglionic mediated contractions achieved by field-stimulation of in vitro isolated detrusor strips. With rats, pelvic nerve stimulation was carried out in vivo and postganglionic stimulation also with isolated detrusor strips.Results: All contractions were abolished by 2% lignocaine indicating they are nerve-mediated. Stimulation targets were verified with hexamethonium that completely abolished pelvic nerve responses by had no effect on detrusor strips; responses to mixed bladder wall stimulation were partially reduced. The frequency-dependence of contractile activation was similar whether by pre- or postganglionic stimulation in both pigs and rats. Sildenafil reduced contractions to preganglionic stimulation significantly more than to postganglionic stimulation. Mixed pre- and postganglionic stimulation were reduced by an intermediate extent.Conclusions: Intramural ganglia offer no frequency-dependent modulation under the experimental conditions used here and the sildenafil data are consistent with multiple sites of action underlying generation of bladder contractions. A translational aspect of these findings is discussed in terms of setting stimulation parameters for neuromodulation protocols.

Authors: Yang Minggen , Xu Zhenqiang , Zhuang Zhiming
Published: September 2021

Purpose: To probe the effect and mechanism of androgen receptor antagonist MDV3100 on benign prostatic hyperplasia (BPH) of ratsMethods: BPH rat model was induced by testosterone propionate. Then antagomir-miR-21-3p or agomir-miR-21-3p was injected into rats before MDV3100 treatment. The prostate index was measured by weighing the wet weight of the rat prostate. The structural morphology of rat prostate was observed after hematoxylin & eosin staining. Immunohistochemistry was applied to evaluate the expression levels of Ki-6 and inflammatory cytokines (interleukin [IL]-6, IL-18, and tumor necrosis factor-α) in rat prostate tissues. Quantitative reverse transcription polymerase chain reaction was utilized for assessment of miR-21-3p expression, and Western blot for the performance of the phosphorylation levels of IKKα and p65.Results: Injection of testosterone propionate caused increased prostate gland hyperplasia, heightened miR-21-3p level, and activated nuclear factor-kappa B (NF-κB) signaling pathway. Additionally, BPH was accompanied by inflammatory response, as evidenced by enhanced expressions of Ki-67 and inflammatory cytokines. MDV3100 exposure ameliorated BPH and suppressed miR-21-3p expression. Overexpression of miR-21-3p intensified BPH and inflammation level, while knockdown of miR-21-3p relieved BPH. The coeffect of miR-21-3p upregulation and MDV3100 subjection led to higher inflammatory response, elevated phosphorylation levels of IKKα and p65 than MDV3100 treatment alone.Conclusions: Androgen receptor antagonist MDV3100 alleviates BPH and inflammatory response through miR-21-3p downregulation and NF-κB signaling pathway blockade.

A review of the contemporary literature on entrepreneurship suggests that, in general, entrepreneurship in the digital sphere is more or less different from " traditional " entrepreneurship. Nevertheless, faced with this assertion, the question that remains slightly discussed is to determine which are foremost the main variables that allow us to compare these two phenomena in order to be able to distinguish them? Based on an in-depth study of variables used in the literature to describe entrepreneurs and their businesses, this paper attempts to introduce a global conceptual model that opens new tracks research to compare, in an empirical way, digital entrepreneurship and traditional entrepreneurship. This framework takes into account three main elements: The entrepreneur profile, the entrepreneurial process and finally the measurement of the venture performance and outcomes. This work also provides useful informations on digital entrepreneurship while demonstrating that it is a complex and multifactorial phenomenon.

Published: September 2021

Фрактальные алгоритмы в природе и творчестве человека открыл Бенуа Мандельброт. Использование фрактальных образов в архитектуре началось лишь в конце XX века, с появлением книг Мандельброта. В статье рассмотрены некоторые здания города Астрахани в сопоставлении с фрактальными моделями. В качестве прототипов, использованы такие графические фракталы как: 1 - элементы самоподобия выявлены на фасадах жилых домов астраханских купцов; 2 – алгоритм Серпинского или «салфетка» Серпинского - является прообразом культовых сооружений, вытянутых по вертикали; 3 – спиральный алгоритм – широко используется в неживой и живой природе, декор в виде раскручивающихся спиралей воплощен в главах храма Федоровской иконы Божьей матери; 4 - «губка» Менгера – прототипом являются прямоугольные панельные здания и параллелепипеды внутренних помещений. Архитектурные формы более регулярны, чем природные, и сочетают малое количество повторов.

The Byzantine Influence on Early Slavic Passion-Bearing Saints
Authors: Saggau Emil Hilton
Published: September 2021

During the Christianization of the early Slavic realms at the turn of the tenth century, a specific type of noble passion-bearing saint came about. Four saints were promoted in short succession in the western, north-eastern, and south-eastern Slavic realms in the span of less than a hundred years. All four were promoted as noble passion-bearing saints and prototypes of the good Christian ruler. These early Slavic saints share many resemblances, and their hagiographies seem to be interdependent. This commonality might be due to them all emerging from the Byzantine tradition and sharing the same hagiographical “typos.” As such, the saints’ hagiographies provide an opportunity to explore not only the relationship but also the internal communications between early Slavic Christian and Byzantine literature as they are expressed in these texts. This article assesses this interaction and traces the shaping of a typology of early Slavic passion-bearing saints.
At Hetmans’ Service: Natives of the Balkans and Podunavlje in the Mercenary Regiments of Cossack Hetmanate in the Mid-Seventeenth through Early-Eighteenth Centuries
Authors: Sokyrko Oleksii
Published: September 2021

The Cossack revolution of the mid-seventeenth century gave an impulse to a wave of conflicts over the Cossack lands that involved almost all Eastern European countries. These companies created a huge demand for Balkan and Podunavljean mercenaries—the armies of all participants hired them. The Cossack Hetmanate had a special interest in recruiting new people because its leaders were working on forming an alternative to their current army based on old military elite. These new recruits were mostly Serbs, Wallachians (Vlachs or Volochs), and Moldavians serving in light cavalry. The campaigns they joined stretched in time; therefore, some of the mercenaries got rooted in the Cossack army, their job transformed into a hereditary service, and their leaders proceeded from military to political matters and grew into the new elite of the Hetmanate.
Temporal Relativism and the Objective Present
Authors: Smith Shelley-Anne
Published: September 2021

An exploration of the possibility of a temporal location for objective reality is undertaken with reference to neurophysiological research demonstrating that consciousness is a function of time-dependent physical processes and that perception of the environment is delayed by at least 80 milliseconds (Eagleman 2010). As empirical research has established that a measurable amount of time precedes conscious awareness, this preconscious time frame satisfies the definition of objective reality as “independent of any perceiver’s consciousness” (Rand, Ayn. 1989. The Voice of Reason: Essays in Objectivist Thought: With Additional Essays by Leonard Peikoff and Peter Schwartz. New York: New American Library, 18). This article uses the term “objective present” to identify the temporal source of information that is subsequently interpreted by organic sensory systems: the milliseconds before conscious awareness.
Move, Stay, or Pay: The Impact of Land Prices on Migration Balances in Germany
Authors: Götzelmann Lukas Felix , Mager Ferdinand , Hennig Kerstin
Published: September 2021

This paper examines the effects of housing costs on net migration in Germany, a country with a polycentric structure. We apply a panel data estimation framework with a large array of unit, time, and regional fixed effects to close to 400 individual counties for the period of 2002 to 2018. Our findings suggest a strong and negative relation between residential land prices and net migration. We conclude that higher land prices can largely offset the additional amenities factored into housing costs and hence cause negative effects on migration. We show that our results are robust to various control specifications, including the addition of variables such as income, education, and age structure, and the use of time lags.

There have been great innovations in the field of real estate appraisal which have replaced the classical methods by recently established modern methods that involve computer technologies known as artificial intelligence. here are several artificial intelligent methods like fuzzy logic and artificial neural networks. In this study, two different real estate appraisal applications that are based on the artificial neural network and fuzzy logic methods are compared. An actual data set is taken from real estate agencies to develop a real estate appraisal model in Samsun city in Turkey. All of the real estate data belong to a certain time interval in May 2020. The selected parameters are scored by a valuation expert and the scores are then subjected to normalization. The obtained values are inputted into a fuzzy logic and artificial neural networks editor in MATLAB software and the valuation model is created. The values we obtain from the artificial neural networks and fuzzy logic are compared with actual sales data. It is observed that using these methods in real estate appraisal provides advantages in terms of time, cost and tangibility, as well as the means to create large database for real estate appraisal in a certain region.

This study aims to analyze the performance of industrial rents and land values in the Sydney property market. In the Sydney industrial property market, no growth of the rents and marginal growth of the land values in real terms has been seen between 1976 to 1996. It means that the overall return from an investment in industrial property is achieved largely from initial yield and current rental incomes, rather than rental growth and capital appreciation. The trends of real growth of industrial rents and land values have a similar cycle, but different magnitude (a or s) of fluctuation. It is concluded that industrial rent is determined more by demand than supply side factors, while land value is determined more by supply side factors than demand side factors.

This paper examines the ability of buyers to afford and upgrade to private housing using the experience in land scarce Singapore as a case study. The concepts of the “threshold buyer?and “threshold upgrader?are introduced to construct an operational inter-temporal model of affordability and upward mobility, taking into consideration income, mortgage rates, prices of public housing flats and the legislative/financing framework in Singapore. The theoretical private property price computed by the upward mobility model is the lower bound dictated by affordability and cash outlay considerations such that the buyer/upgrader is no better or worse off arising from changes in the relevant factors over time. The model is empirically tested to evaluate the theoretical underpinnings as well as the ability of the model to predict private property price. Finally, the paper examines the implications for housing ownership policy in a wider context.

This article discusses the advantages and disadvantages of real estate-related taxes that might be imposed in mainland China, in light of the government’s needs for tax revenue and the economy’s need for incentives to develop land. Some policy recommendations are presented, based on an analysis of real estate taxation in general and of China’s specific needs. As one recent article has noted, understanding how behavior adjusts in response to taxation is one of the most important issues in public finance.

In an efficient market, differences in quality should be fully reflected in differences in price. This paper examines a highly active residential property market and verifies whether housing attributes can explain time on the market (TOM) in addition to prices. In contrast to the previous literature, only the price ratio and inflation factor are found to be critical in affecting TOM. An interpretation of the results is suggested, along with some directions for future research.

Real estate investments are typically characterized by high degrees of leverage and long-loan tenures. In perfect capital markets, leverage has no impact on the investment decision apart from tax considerations. However, the mortgage financing market is imperfect in many countries. In the presence of market imperfections, an optimal holding period exists for real property investments. We provide a simple rule to calculate the optimal holding period to compare the required rate of return with the leveraged rate of return on equity.

Hong Kong is well known for its “housing market bubble”. Both theoretical and empirical studies point to the supply side being the “root of all evil”. This paper takes a preliminary step in understanding the supply side of the Hong Kong market by investigating the construction and related industries. After taking into consideration of the unusual public expenditure, the construction industry seems to be “normal” in international standard. Its relationship with the aggregate economy is also examined. Directions for future research are also suggested.

Initial research on calendar anomalies has shown their existence for real estate investment trusts (REITs) and for the general stock market. Recent studies of the general stock market, however, have shown that these anomalies have disappeared or been reversed over time. The present research updates existing REIT calendar anomaly research through the use of value-weighted and equal-weighted REIT indices and the decomposition of income and capital returns. From 1994 to 2002, the presence of calendar anomalies is sensitive to the use of REIT index type as well as the dividend yield and capital yield components. The use of the value-weighted index eliminates the appearance of calendar anomalies in REITs.

We explore the effect of mortgage curtailment payments on subsequent default probabilities. Although curtailment is not popular in western countries, it is the dominant form of prepayment in Asia. Using more than 6 years of mortgage performance records from an Asian bank, we investigate the impact of curtailment payments on mortgage default risk. The results of logistic regressions reveal that the cumulative curtailment is the most significant factor in predicting the future default probabilities of a seasoned mortgage pool. Thus, mortgage modeling for Asian countries should be different from mortgage modeling for western countries.
5th-grade Students' Misunderstandings and Misconceptions about Fungi

Published: September 2021

The fungi kingdom is among the important topics of biology, and students can develop misunderstandings and misconceptions about this subject.This study aims to determinemisunderstandings and misconceptions of 5th-grade students about fungi. The participants of the study consisted of 22 (12 girls, 10 boys) fifth graders of an elementary school in Erzurum city center, which was determined by the convenience sampling method. In this qualitative study, a 'semi-structured interview form' was used. The form includes 16 open-ended questions prepared following the learning outcomes of the curriculum. The data collected in the study were subjected to descriptive analysis and the findings were presented by calculating the frequency and % values. The findings indicate that the students have misunderstandings and misconceptions on the structure of mold, yeast, and fungi, their feeding, whether they are alive, their classification, reproduction, living conditions, etc.At the end of the study, some suggestions were made on the teaching of the biology concepts with examples from daily life, usage of visual elements during teaching, more laboratory applications. It is also suggested that similar studies should be implemented with different grade levels and sample groups.

Mục đích: Tổng quan về phương pháp và các nghiên cứu đánh giá hiệu quả bệnh viện đã được thực hiện tại Việt Nam.
Kết quả: Phương pháp phân tích bao dữ liệu (Data envelopment analysis-DEA) - mô hình phi tuyến tính tĩnh; và phân tích biên ngẫu nhiên (Stochastic frontier analysis-SFA) - mô hình tuyến tính động; là hai phương pháp phổ biến nhất trên thế giới được sử dụng để đo lường hiệu quả bệnh viện. Tại Việt Nam, các nghiên cứu đều sử dụng phương pháp DEA để đo lường hiệu quả kết hợp với mô hình hồi quy Tobit hoặc Truncated để tìm mối liên hệ của các yếu tố khác ảnh hưởng đến hiệu quả hoạt động bệnh viện.
Kết luận và khuyến nghị: Lựa chọn DEA để đo lường hiệu quả bệnh viện ở Việt Nam thời điểm hiện tại là phương án tối ưu nhất. Phương pháp Bootstrap có thể giúp gia tăng độ tin cậy kết quả DEA. Tuy nhiên, DEA chỉ nên được xem như điểm khởi đầu cho phân tích quản lý. Cần tiến hành tìm hiểu sâu hơn nguyên nhân khiến các đơn vị hoạt động không hiệu quả trước khi đưa ra những khuyến cáo liên quan đến cắt giảm đầu vào.
STABILIZING THE PERIODIC ORBITS IN A CHAOTIC MAPPING DESCRIBING THE DISCRETE HEALTH SYSTEMS VIA PREDICTION-BASED CONTROL
Authors: DELEANU DUMITRU
Published: September 2021

In the paper the problem of location and stabilization of unstable periodic orbits (UPOs) in discrete systems is investigated via the prediction-based control (PBC). It involves using the state of the free system one period ahead as reference for the control signal. Two types of control gains are tested, the first requiring the knowledge of the UPO to be stabilized and the second depending only on the actual state of the trajectory. The effectiveness of PBC is demonstrated on a chaotic mapping describing the malignant tumor growth. When the results obtained with the two control laws are compared with each other, it is found that the second variant is qualitatively superior, both in terms of convergence and the number of stabilized UPOs, especially for long-period orbits.
