Identification in simple binary outcome panel data models

This paper first reviews some of the approaches that have been taken to estimate the common parameters of binary outcome models with fixed effects. We limit attention to situations in which the researcher has access to a data set with a large number of units (individuals or companies, for example) observed over a number of time periods. We then apply some of the existing approaches to study fixed-effects panel data versions of entry games, like the ones studied in Bresnahan and Reiss (1991) and Tamer (2003).
An Insight to the Degradation Behaviour of the Parallel Connected Lithium-Ion Battery Cells

In an electric vehicle, a large number of lithium-ion cells are connected in parallel. While cells in parallel increase the reliability of the battery pack, it increases the probability of current imbalance between the parallel branches, thus ageing gradient. The current peak in a cell also can exceed the maximum charge current capability of the cell; leading to lithium plating, therefore a safety issue. The temperature gradient within a battery pack amplifies this issue. This work reports the impact of such temperature gradient on current imbalance within parallel connected cells, their long-term impact on degradation and evaluation of current distribution with degradation. Employing a real-world relevant experimental setup, a total of 1400 cycles were performed on a module with four cells in parallel. A temperature gradient of 10 °C was introduced among the cells, and current in individual parallel branches was measured employing Hall-effect sensors. Over the course of the experiment, module capacity decreased by 23.6%. Cells at higher temperature/lower exposure to active cooling experienced higher degradation. However, the cell with the lowest starting capacity, although exposed to nominal module temperature and cooling experienced the highest current amplitude towards the end of discharge/charge and thus the highest resistance degradation. It was found that current in an individual parallel branch was exceeding the maximum rated charge/discharge current by 53%.
The Effect of Energy Usage, Economic Growth, and Financial Development on CO2 Emission Management: An Analysis of OECD Countries with a High Environmental Performance Index

The environmental performance index was developed to protect public health, and to sustain and manage the ecological vitality that is a crucial factor in countries’ social and economic development. The increase in CO2 emissions has been threatening environmental and human health. The main objective of this study is to evaluate the impact of economic growth, energy consumption, energy management, the urban population, trade openness, and financial development on CO2 emissions in the OECD countries that have a high ranking in the environmental performance index by utilizing the panel data analysis method for the years spanning 1990–2014. This assessment finds positive relationships between economic growth, energy consumption, and the urban population, and CO2 emissions. Moreover, it is put forward that a negative and significant relationship between financial development and CO2 emissions exists. Despite displaying a similar negative correlation, the relationship between trade openness and CO2 emissions is insignificant. In the Dumitrescu-Hurlin panel causality test conducted, it was seen that a two-way causality is prevalent between energy consumption and CO2 emissions. In addition, interrelations where CO2 emissions cause trade openness, and the urban population is an explanatory variable of the former relationship, were discovered.
Development of modern payment methods in Poland as an example of technological leapfrogging

In the Polish economy consumers can choose from various payment methods. Every method has its advantages and disadvantages. The literature on the subject includes numerous studies proving the higher cost-effectiveness of electronic payments, e.g. using payment cards. Poland is in the group of countries where people rather pay in cash than by payment cards. However, payment innovations are quickly adopted. In the second half of 2018 Poland was the first country in the world in which all payment terminals accepted contactless payments. This was possible thanks to top-down activities (e.g. Cash Support Program) but also thanks to the quick adaptation of these new payment methods by a large part of our society. This could be associated with a relatively shorter period of operation of non-cash payments, which made adaptation of the innovation easier than in other countries already using non-cash payments for some time. The concept of implementing the latest technologically advanced stage without the previous stages is called leapfrogging. The implementation and dynamic development of the latest payment technologies on the Polish market make use of the characteristic of this process, although it is not literal. Interestingly, after the implementation of modern payment methods the processes of further development of payment methods (BLIK system) began in our country, which gained the interest of the global payments giant (Mastercard). Therefore, we are not only adopting technology but also entering the group of technological leaders in the sphere of payments.
Structural Change in Labor Supply and Cross-Country Differences in Hours Worked

This paper studies how structural change in labor supply along the development spectrum shapes cross-country differences in hours worked. We emphasize two main forces: sectoral reallocation from self-employment to wage work, and declining fixed costs of wage work. We show that these forces are crucial for understanding how the extensive margin (the employment rate) and intensive margin (hours per worker) of aggregate hours worked vary with income per capita. To do so we build and estimate a quantitative model of labor supply featuring a traditional self-employment sector and a modern wage-employment sector. When estimated to match cross-country data, the model predicts that sectoral reallocation explains more than half of the total hours decrease at lower levels of development. Declining fixed costs drive the rise in employment rates at higher levels of income per capita, and imply higher hours in the future, in contrast to the lower hours resulting from income effects and expansions in tax-and-transfer systems.
Development of Strength Abilities Using Play Techniques with Elements of Martial Arts at the Sports and Recreational Stage in 10-Year-Old Girls

The objective of the study was to examine the level of strength fitness indicators of 10-year-old girls and experimentally test the effectiveness of the impact of play techniques with elements of martial arts on the dynamics of strength development. Materials and methods. The study participants were 20 10-year-old girls who do Kyokushin Karate. The children and their parents were informed about all the features of the study and gave their consent to participate in the experiment. The following research methods were used to achieve the objective set: analysis of scientific and methodological literature, pedagogical testing, and methods of mathematical statistics for processing research results. Results. There were the biggest changes in the results of the tests “Lying pull-ups” by 51.1% (p < 0.05), “Push-ups” by 34.1% (p <0.05), and “Bent arm hang” by 26.5% (p < 0.05). Somewhat smaller changes were observed in the tests “Right hand grip test” by 10.8% (p < 0.05), “Left hand grip test” by 10.5% (p <0.05), and “Sit-ups in 1 min” by 13.3% (p < 0.05). The lowest increase in the results was observed in the test “Triple jump on the right and left leg” by 6.6% (p < 0.05). Conclusions. The level of the girls’ strength fitness at the initial stage of the pedagogical experiment conforms to age norms. Most of them are at the average – 40% and above average – 23.6% levels. The remainder of indicators was distributed between the high – 13.6%, below average – 14.3%, and low – 8.6% levels. A comprehensive control of the 10-year-old girls’ strength fitness after the formative experiment showed statistically significant changes in almost all indicators in the experimental group, which used play techniques with elements of martial arts in the following load mode: 5 games, 2 repetitions with rest intervals of 40 s (p < 0.001).
An Assessment of Barriers to MSMEs’ Adoption of CSA in Livestock Red Meat Value Chain, Kajiado County, Kenya

Climate change poses great risks to poverty alleviation, food security and livelihoods sustainability in sub-Saharan Africa, declining crop yields and livestock productivity, especially in ASALs that suffer from fragile ecosystems characterized by frequent droughts and low rainfall. Climate-Smart Agriculture (CSA) objectives of improving productivity and incomes, adaptation, resilience to climate change and mitigation on GHGs emissions, are responses to these climate risks. CSA technologies, innovation and management practices (TIMPs) in general do exist, however they are concentrated in crop farming neglecting livestock production and especially in marginalized areas such as ASALs, which forms 85% of Kenyan land mass and is dominated by pastoral and nomadic livestock production. Most CSA practices are mainly at the production level and hardly extend to the entire value chain, and diffusion is slow due to several barriers. A mixed method approach was used to evaluate barriers to actors’ adoption of CSA in the pastoral Livestock red meat value chain starting from input suppliers, producers, to consumers (pasture to plate). This study used six broad perspectives to examine the barriers: 1) Knowledge and institutional; 2) Market and financial; 3) Policy and incentives; 4) Networks and engagement platforms; 5) Cultural and social; 6) Physical infrastructure barriers. These barriers can be surmounted with concerted efforts from the government, development partners, pastoral communities, value chain actors and public private partnership among others. Efforts such as modernization of the pastoral red meat value chains, integration of MSMEs into the livestock systems, access to affordable financing, availability of context based, affordable CSA TIMPs, incentives, policies and institutional support, which currently remains inadequate. Institutional barriers like lack of capacity, coupled with knowledge and behavioral barriers hinder adoption. Financial institutions and cooperative societies can be enablers, however, their reluctance to invest in the sector is a barrier too.
Ten Rules of Foot Care—The Development of a Short Questionnaire for Patients with Diabetes

Objective: The aim of this study was to develop and validate a questionnaire for patients with diabetes to assess the foot self-care. Methods: A validation study was carried out in a sample of 200 patients with diabetes. Item analyses included the assessment of difficulty index, discrimination capacity and the correlation of items with the total score of the questionnaire. Factor analysis was used to test construct validity. Test-retest reliability was assessed with a sample of 31 patients. Criterion validity was determined by comparing the scores of patients with a history of foot ulcers with the scores of patients without this complication. Results: The internal consistency assessed by the Cronbach’s alpha (0.731) and test-retest reliability (r = 0.714, p = 0.001) for all sections were acceptable. Factor analysis revealed three factors: foot care, footwear and foot-damaging behavior, which explained 54.34% of the variance. All items had factor loading of greater than 0.4. Patients with diabetic neuropathy had a lower score after completing the foot care education questionnaire (Mann-Whitney U, p < 0.001). Conclusion: This questionnaire meets the reliability and validity conditions necessary for its application in our patients with diabetes.
Co-evolution of Construction Waste Recycling Industrial Chain Based on Lotka–volterra Model

Under the green building policy, the recycling of construction waste has become an important issue. However, many obstructions in the industrial chain of construction waste recycling, slow integration of production elements in the chain, and inefficient resource allocation hinder the development of the construction waste recycling industry. In this study, a co-evolution model of the industrial chain of construction waste recycling is constructed based on the Lotka–Volterra model, and the Jacobian matrix is used for stability analysis. Finally, a numerical simulation is performed. The simulation results indicate that: (1) There is a high product correlation between upstream and downstream enterprises in the industrial chain of construction waste recycling; (2) The conversion coefficient of supply and demand of upstream and downstream enterprises has a higher impact on and is more sensitive to the evolution of this industrial chain; (3) The co-evolution of upstream and downstream enterprises promotes the added value of products and maximizes the overall benefits of the industrial chain, which provides reference value and theoretical basis for the development of the industrial chain of construction waste recycling.

Property Analysis of Slag Composite Concrete Using a Kinetic–Thermodynamic Hydration Model

Slag is increasingly unitized for the production of sustainable concrete. This paper presents a procedure with which to analyze the property development of slag composite concrete. Experimental studies of the hydration heat and compressive strength development and simulation studies using a kinetic hydration model and a thermodynamic model were performed. First, we performed an experimental study of the isothermal hydration heat of cement–slag blends. Based on the results of the experimental study on cumulative hydration heat, the reaction degree of slag was determined. We found that the reaction degree of slag decreased as the slag content increased. Second, the reaction degree of slag and cement were used as the input parameters for the Gibbs energy minimization (GEM) thermodynamic equilibrium model. Moreover, the phase assemblage of hydrating cement–slag was determined. The trends of calcium silicate hydrate (CSH) are similar to those of strength. Based on the CSH content, the strength of hardening cement–slag blends was determined. In addition, the calcium hydroxide (CH) content resulting from the thermodynamic model shows good agreement with the experimental results. In summary, the integrated kinetic–thermodynamic model is useful for analyzing the properties of cement–slag blends.
PAGEANT: personal access to genome and analysis of natural traits

GWASs have identified numerous genetic variants associated with a wide variety of diseases, yet despite the wide availability of genetic testing the insights that would enhance the interpretability of these results are not widely available to members of the public. As a proof of concept and demonstration of technological feasibility, we developed PAGEANT (Personal Access to Genome & Analysis of Natural Traits), usable through Graphical User Interface or command line-based version, aiming to serve as a protocol and prototype that guides the overarching design of genetic reporting tools. PAGEANT is structured across five core modules, summarized by five Qs: (1) Quality assurance of the genetic data; (2) Qualitative assessment of genetic characteristics; (3) Quantitative assessment of health risk susceptibility based on polygenic risk scores and population reference; (4) Query of third-party variant databases (e.g., ClinVAR and PharmGKB); and (5) Quick Response code of genetic variants of interest. Literature review was conducted to compare PAGEANT with academic and industry tools. For 2,504 genomes made publicly available through the 1,000 Genomes Project, we derived their genomic characteristics for a suite of qualitative and quantitative traits. One exemplary trait is susceptibility to COVID-19, based on the most up-to-date scientific findings reported.
Structure–Property Relationships for Weak Ferromagnetic Perovskites

Despite several decades of active experimental and theoretical studies of rare-earth orthoferrites, the mechanism of the formation of their specific magnetic, magnetoelastic, optical, and magneto-optical properties remains a subject of discussion. This paper provides an overview of simple theoretical model approaches to quantitatively describing the structure–property relationships—in particular, the interplay between FeO6 octahedral deformations/rotations and the main magnetic and optic characteristics, such as Néel temperature, overt and hidden canting of magnetic sublattices, magnetic and magnetoelastic anisotropy, and optic and photoelastic anisotropy.
The Effects of Terrorism and Economic Indicators on Bank Loans to the Private Sector: Evidence from Developing Countries

ABSTRACT Herein, factors affecting domestic bank loans to the private sector are determined within the context of ten developing countries. The relationship between bank loans to the private sector and the gross domestic product (GDP), interest rates, exchange rates, and terrorist incidents is investigated using the autoregressive distributed lag bounds test and cointegration regression models. According to the results obtained from the models developed by applying annual data from 1970–2018, a positive relationship between domestic bank loans to the private sector, which is the endogenous variable, and the GDP, and a negative relationship with interest rates, terrorist incidents, and exchange rates are observed. Particularly in countries where terrorism is intense, investors giving up or postponing investments owing to the deterioration of the investment climate decreases loans to the private sector. Accordingly, terrorism should be considered and managed as an operational risk factor in the banking sector. We also find empirical evidence that capital control practices in some countries decrease bank loans to the private sector.
Code of ethics and conduct in the light of corporate governance: the stakeholders' perspective

Purpose: To evaluate the theme "Code of Ethics and Conduct" in private or public organizations, considering the relationship between ethical issues and good practices in Corporate Governance, measures that subsidize the planning and strengthening of ethical cultures in the interpersonal context.Design / methodology / approach: The descriptive survey relied on the application of questionnaires and obtained 184 responses from organizations of various types. The study was carried out using codes of conduct made available by companies on their websites, characterized as primary sources. The data collected were worked in the SPSS, tabulated and presented as results in the form of tables or graphs, with appropriate analyses.Findings: The results show the adoption of good practices of integrity, especially on the Code of Ethics and Conduct. The adoption of an ethical code can be considered a way to formalize, encourage and guide responsible behavior among employees and organizations. Seen from the outside, it contributes to creating and maintaining a good corporate reputation and stakeholder trust. In this sense, the reasons behind the creation of a code have been stated in the Shareholders' Theory, the Legitimacy Theory and the Stakeholder Theory.Originality / value: The Code of Ethics and Conduct arises as an instrument to guide ethical behavior in organizations. Therefore, it is the declaration of the set of rights, duties, business conduct towards stakeholders, reflecting the culture and set of norms that enrich the company's decision-making processes and guide its behavior.
Physics-Based Neural Network Models for Prediction of Cam-Follower Dynamics Beyond Nominal Operations

Cam-follower mechanisms are key in various mechatronic applications to convert rotary to linear reciprocating motions. The dynamic behavior of these systems relies on the design parameters such as the cam shape and follower mass. It appears that for some combinations of system parameters, continuous contact between the cam and follower cannot be assured, leading to harmful periodic impacts. This research presents a data-driven approach to predict the influence of parameter settings on the system dynamics by learning from a limited data set of nominal operating conditions. More specifically, we present a hybrid model architecture encompassing an ordinary differential equation, consisting of a close interconnection of neural and physics-based network layers. Due to an increased generalization established by the physical laws, these physics-based neural network models exhibit enhanced extrapolation capabilities compared to their black-box counterparts. Consequently, the presented models can accurately simulate the system behavior for parameter settings far beyond the nominal values included in the training data. This way, starting from a limited set of nominal time-series data, we could accurately estimate the set of critical system parameters that lead to hazardous jump phenomena in cam-follower systems.
Adaptation to Emergency Online Education: A Case of Oral Communication Skills Course in ELT

The significant growth of the cases all around the world caused by the Covid-19 pandemic necessitated the intermittent closures in higher education in March, 2020 in Turkey. Yozgat Bozok University started online education synchronously and asynchronously via Google Meet and Google Classroom. This paper aims to present ELT students’ online experience in carrying out Oral Communication Skills course adapted to distance learning. Secondly, by conducting qualitative research methods, it presents students’ standpoints concerning the problems they faced with an unplanned and unprepared online education. The researcher sent reflective writing questions to students and then arranged online interviews. Qualitative data were analyzed by NVivo 12 and learner-reported data bring fruitful insights on students’ attitudes towards Google Meet and Google Classroom. It is founded that these applications increase students’ interaction and help them promote communication skills. However, poor internet connection and lack of internet access are noted by all the participants as a basic problem for online education. The present study drawing on current distance learning literature suggests instructors to design student-centred online environment to foster student participation.
