Abstract
Cocoa (Theobroma cacao) seedlings are very sensitive to water stress during the nursery stage and early field establishment. Sawdust, carbonated rice husk, and compost in the following ratios (i) 60: 40: 0 – M1, (ii) 60: 30: 10 – M2, (iii) 60: 20: 20 – M3, (iv) 60: 10: 30 – M4, (v) 60: 0: 40 – M5, and (vi) topsoil – M6 as control were used to investigate the effect of growing media, water stress, and re-watering on the growth, dry matter production, and partitioning of cocoa seedlings. Each combination was subjected to water stress 6 weeks after sowing for a period of 4 weeks, after which they were rewatered. Plant height, stem girth, leaf number and area, and seedling biomass were significantly higher in soilless potting media as compared to topsoil. M4 and M5 significantly recorded the highest total dry weight, plant height, stem girth, leaf number, leaf area, and root volume before imposition of water stress. Following imposition of water stress, cocoa seedlings grown in M4 and M5 showed a recovery that was superior to the other growing media, indicating that higher proportions of compost together with sawdust and carbonated rice husk provide an alternative for growing cocoa seedlings.

Abstract

Subject and purpose of the work: Working time management has become particularly relevant by mid-20th century. It has now become one of the top areas of interest for scientists who conduct research on management. This study is designed to review and evaluate selected new forms of work organization in the reality of today’s digital economy.

Materials and methods: This research was based on literature review covering scientific publications exploring working time management and forms of work organization in the digital economy. A descriptive method was used.

Results: The latest information technologies, computerization and digitization, the use of mobile devices and smartphones, and advanced geolocation technologies add a new dimension to the modern types and methods of working time management. The development of the digital economy accelerates and drives the transformation of the labor market, promoting the uptake of flexible employment systems, which produces multiple types of remuneration and working time systems, and leads to a variety of forms of employment contracts and their reduced duration.

Conclusions: Digital technology creates a virtual labor market which is dominated by informal and flexible forms of employment based on outsourcing programs, individual orders, and fixed deadlines with are not accompanied by any regulations of the contractor’s working time. Under these conditions, flexibility and multifunctionality, and the ability to adapt to changing conditions are the key features that make a particular employee competitive.

Published: January 2023

Abstract

Subject and purpose of the work: This study examined water accessibility challenges, and the implications on children in rural border communities of Nigeria.

Materials and methods: Primary data were used, and children (5-16 years) were respondents to the interview and questionnaire.

Results: The study revealed there were more male children (58%) than female children (42%) and many of them were in the age bracket 11–15 years with about (53.9%) of them without formal education. The results further revealed that 69.9% of the respondents indicated that their major source of water is a stream and river. Also, the majority of the respondents (71%) trek long distances and (82.9%) spend more than 30 minutes travelling to collect water in distant villages especially during the dry season. This situation usually takes them away from their education and even affect their school attendance.

Conclusions: The study recommended the need for the equitable provision of an improved water supply and ensure children are secured in collecting water for their households.
Spatial patterning of Gonystylus brunnescens in eastern Borneo
Authors: Brearley Francis Q. , Mansur Muhammad , Eichhorn Markus P. 
Published: January 2023

Abstract
Determining the spatial patterning of tree species can provide inferences on underlying ecological processes. Gonystylus brunnescens is a South-east Asian subcanopy forest tree. To determine the spatial patterns of this species, we recorded the distribution of all individuals in a 0.4 ha sampling plot in eastern Borneo. We found that the pattern deviated from random and was well-described by the Matérn cluster model; clusters had a radius of approximately 4.2 m and contained an average of six seedlings each. This supports the hypothesis of animal-dispersed seeds and, due to a clear lack of association of juveniles with adults, may be due to scatter-hoarding of seeds by small mammal seed dispersers.

Published: January 2023

Abstract
The ability to estimate the space volume that a tree occupies, in various heights, is a crucial factor in designing the street trees schedule in pavements of new urban infrastructures. The dimensions of Acer negundo tree crown in various heights can be the basis for a better space management in the pavements of cities. In this study, the height and the crown width of the A. negundo street trees in the Greek cities of Orestiada and Alexandroupoli and the allometric relations that can be found between them, were investigated. Data from 117 street trees growing in semi-permeable pavements of the two cities were used. In each selected tree, the total height (H), and the maximum and minimum crown diameter (CW) were measured. The selected model (CW-H) for Alexandroupoli exhibits a coefficient of determination (R2) of 0.81. The R2 of the model selected for Orestiada is lower (R2 = 0.66). The R2 of the model selected using the complete dataset is 0.77. A. negundo appears to have greater crown width in Alexandroupoli compared to that of Orestiada. In Orestiada the conditions of growth were variable since in many cases the measured trees were under side shade, while this not the case in the corresponding trees in Alexandroupoli. The better fit of the selected model in Alexandroupoli compared to that of Orestiada is probably due to the more variable growth conditions of Orestiada.
Adhesion Molecules and Vulnerable Plaques – Promoters of Acute Coronary Syndromes
Authors: Opincariu Diana , Benedek Theodora 
Published: January 2023

Abstract
Biological factors that characterize extrinsic plaque vulnerability include various pro- and anti-inflammatory cytokines that contribute to the development and progression of atherosclerosis. Adhesion molecules are among the initiators of the atherosclerotic process, by mediation of endothelial inflammation. The soluble forms of these adhesion molecules have been identified in the circulatory blood, with an increased level in case of subjects with atherosclerotic lesions and higher levels in patients with acute coronary syndromes or vulnerable plaques. In addition, several authors have found a significant predictive capacity of these molecules in case of patients presenting with acute coronary and cerebrovascular events. The aim of this manuscript is to provide a short description of the role of adhesion molecules in the development and progression of atherosclerotic lesions towards acute coronary syndromes, as well as their capacity for predicting major adverse cardiovascular events in vulnerable cardiovascular patients.
Go First Dice for Five Players and Beyond.
Authors: Ford Robert , Grime James , Harshbarger Eric , Pollock Brian 
Published: January 2023

Abstract
Before a game begins, the players need to decide the order of play. This order of play is determined by each player rolling a die. Does there exist a set of dice such that draws are excluded and each order of play is equally likely? For four players the solution involves four 12-sided dice, sold commercially as Go First Dice. However, the solution for five players remained an open question. We present two solutions. The first solution has a particular mathematical structure known as binary dice, and results in a set of five 60-sided dice, where every place is equally likely. The second solution is an inductive construction that results in one one 36-sided die; two 48-sided dice; one 54-sided die; and one 20-sided die, where each permutation is equally likely.

Published: January 2023

Abstract
Countries with a higher proportion of tertiary education graduates are wealthier and offer more diverse and motivating career opportunities to individuals, including students. In recent years, an increasing number of studies have examined the impact of education on wages and economic development and the impact of R&D and innovation on economic and social progress. However, research has focused less on the specific impact of education components (competencies, learning methods, information and communications, technology, and infrastructure) on economic development and innovation. The paper uses quantitative research methodology and dynamic panel models explore the impact of education on economic development, wages, and innovation in the European Union countries and countries that participate in PISA testing, over the period 2012-2019. The data was gathered from Eurostat, and the time period studied ranged from 2012 to 2019. We found evidence that the substantial funding of R&D and education, which promote innovation, supports a country’s need to develop and distinguish itself from others that underfund the most critical areas of economic development. The implications of this study are significant for Romania’s academic and political environments, as it encourages changes in educational policies that will consider the multifaceted impact of educational components on development through innovation.
A Review of the Literature on International Joint Ventures: A Bibliometric Study for the Period 1975-2019
Authors: Costa Francisco , Forte Rosa 
Published: January 2023

Abstract
Extensive literature on the subject of International Joint Ventures (IJVs) has developed during the last few decades. This work aims at identifying the main trends in this literature using a bibliometric analysis. The analysis of 507 studies published between 1975 and 2019 has allowed for the identification of key authors and journals and has revealed that the literature is focused on topics related to performance and success factors, knowledge acquisition and management, control and developing economies such as China. Thus, future research can focus on topics that have been neglected such as corporate social responsibility, legitimacy and absorptive capacity, and the study of countries and regions relatively neglected.

The current paper aims to bring forward the importance of social media profiling in the marketing activity while underlining some important theoretical aspects about social media and profiling and at the same time presenting the results over short secondary data analysis that shows some general profiles for Instagram and TikTok user, with a direct link to the evolution of the revenues generated by the advertising done on the two mentioned social media platforms.
The State as a Driver for Good Corporate Governance of State-Owned Enterprises
Authors: Keremidchiev Spartak , Nedelchev Miroslav 
Published: January 2023

Abstract
The state, represented by the legislature and the executive power, is committed to create a pattern for good corporate governance of state-owned enterprises (SOEs). First attempt to formulate such principles for private companies listed in the stock exchange emerged in the UK. Considering the size and importance of state sector, the Organization for Economic Co-operation and Development (OECD) gradually adopted and recommended similar principles for SOEs. They are the most commonly recognized and accepted pattern for good corporate governance of SOEs throughout the world. The study aims to evaluate the current level of compliance with these principles in Bulgaria (2016–2018) by state authorities and to find the gaps in their implementation. To achieve this aim, an original methodology has been developed derived on OECD principles and the use of expert assessment. The study found that the state (Parliament and Council of Ministers) has established in relatively high degree compliant with OECD principles of good corporate governance of SOEs pattern, while the ministries-principals of SOEs have insufficiently complied with these principles. They need to devote a lot of attention and endeavors to fill the gaps in complying with these principles and to create a modern corporate governance pattern for SOEs.
Using Graph Theory to Optimize Career Transitions
Authors: Otto James , Chaodong Han , Fisher Ke Jian-Yu 
Published: January 2023

Abstract
Grounded in graph theory, this paper proposes and demonstrates a novel methodology to analyze career transitioning. We collect and integrate official U.S. Government data on 35 general job skills and the annual wage data for over 900 standard occupations. Our research can help people move from unemployment, or a current job, to their desired occupation. We use graph theory to determine the most efficient way to hop between intermediate jobs to gain the necessary set of skills required by the targetted occupation. Our analysis assumes that working in a job proffers the skills from that job to the employee. A potential application involves an employee who wishes to transition to a different occupation, perhaps even in a different industry. The employee does not have the necessary skills to transition directly to the desired career because the skill levels are too different between the jobs. Instead, the employee must make a series of smaller job hops to acquire the skills. This type of analysis can provide valuable insights into the most efficient way to change careers. Our study may be especially relevant and helpful because some employees may need to move from languishing careers or industries to ones less impacted by COVID 19 or less threatened by automation.
Insider Trading, Stock Volatility, and Market Liquidity in the Korean Capital Market
Authors: Pyo Gyungmin 
Published: January 2023

Abstract
While the positive and negative effects of insider trading have been discussed in the each firm levels, there is little evidence for the effects of insider trading on financial markets. This paper aims to provide empirical evidence for the effects of insider trading in the capital market. This study examines the association between insider trading and information asymmetry in firms with certain information environments. If capital market regulation for insider trading is effective and companies are well-governed, the positive rather than negative effects of insider trading in the capital market will be enhanced. The empirical results indicate that insider selling (buying) in firms with high ratios of foreign share ownership is associated with a decrease in stock volatility (market liquidity). The results in this paper enables policy makers and practitioners to understand the impact of corporate insider trading on outsiders in the capital market. Our findings may also help to reform regulation of insider trading as it is applied in real business environments, especially in firms with high levels of information asymmetry.

Authors: Roşu Bogdan , Cordun Mariana 
Published: January 2023

Abstract

Introduction. Patients with knee injuries may be consulted in a first stage by specialists, such as the sports doctor, and in a second stage, depending on the severity of the injury and the therapeutic orientation, it may be necessary to consult an orthopedic surgeon and / or medical rehabilitation.

Aim. Particularly important in the traumatic pathology of the knee is the physical examination. It must be rigorous and systematic, because, based on it, a correct diagnosis can be established, which also assesses the severity of the lesions. Only in this way the optimal therapeutic decision be made in order to establish an accurate initial diagnosis and to evaluate the severity of the sprain, depending on which medical or orthopedic-surgical treatment is decided.

Methods. Complete and accurate physical examination in the knee sprain, begins with a meticulous anamnestic interview, followed by inspection and palpation. The examination ends with a series of maneuvers to test the various potentially damaged structures of the knee.

Results. All the listed elements will allow us to establish the therapeutic management in the recent sprain of the knee and to differentiate the affected structures: sprain with the interest of the collateral ligaments or with the damage of the central pivot, represented by the cruciate ligaments.

Conclusion. Although with the advent of imaging investigations methods, which provide particularly important information and the diagnosis becomes much simplified, the stage of the physical examination of the patient in the knee sprain should not be omitted, it is an accessible and extremely useful tool in the orientation toward diagnosis.

Pada tahap perkembangan emerging adulthood, seseorang akan melakukan eksplorasi identitas. Dukungan orangtua yang terutama dikomunikasikan melalui peristiwa sehari-hari, masih dibutuhkan emerging adult. Permasalahan muncul saat emerging adult tidak mempersepsikan apa yang dikomunikasikan orangtua sebagai dukungan sehingga emerging adult tidak bersedia terbuka pada orangtua. Tujuan penelitian ini adalah untuk melihat hubungan antara persepsi komunikasi suportif orangtua dan self-disclosure pada emerging adult. Partisipan penelitian ini adalah 391 mahasiswa yang berada pada rentang usia 18 hingga 25 tahun dan tinggal di rumah bersama kedua orangtuanya (tidak tinggal di kost) dan berdomisili di Jabodetabek. Peneliti mendapatkan partisipan melalui metode non-probability sampling dengan teknik convenience sampling. Dalam menjawab pertanyaan penelitian, peneliti menggunakan alat ukur Skala Komunikasi Suportif Orangtua dan The Jourard Self-disclosure Questionnaire untuk selanjutnya dilakukan uji korelasi. Hasil korelasi menunjukkan bahwa terdapat hubungan yang signifikan antara persepsi komunikasi suportif orangtua dan self-disclosure pada emerging adult. Hal ini menunjukkan bahwa semakin baik persepsi komunikasi suportif orangtua, maka emerging adult akan semakin terbuka.
