Involvement of Ethylene in Physiological Processes Determining the Vase Life of Various Hybrids of Mokara Orchid Cut Flowers

There is limited information about the postharvest performance and physiology of Mokara orchid cut flowers, which are a special group of artificially created trigenetic hybrids of Vanda × Arachnis × Ascocentrum. Therefore, we first characterized the patterns of various physiological parameters during vase life of five Mokara hybrids, which differ in their longevity. Then, we examined the effects of ethephon and ethylene inhibitors on these physiological parameters, and on parameters of the ethylene biosynthesis pathway, during vase life of two selected Mokara hybrids, “Moo-deang” and “Dao-lai”, which showed significant differences in their vase life duration and senescence symptoms. The results demonstrate that the differences in vase life longevity among the five Mokara hybrids are due to differences in their ethylene production rates, which regulate flower development processes expressed in bud opening and floret senescence. The results clearly show that ethylene is involved in the regulation of the Mokara flower senescence, and pretreatment with ethylene inhibitors significantly improved their vase life longevity. Thus, ethylene seems to be the main factor that determines the longevity differences of the Mokara hybrids, rather than their water relations parameters. This study can serve as a research tool for developing effective postharvest treatments for Mokara hybrids.
Psychometric Properties of Questionnaire of Cognitive and Affective Empathy (QCAE): Reliability and Factor Analysis Study in Turkish Sample

Introduction: The Questionnaire Cognitive and Affective Empathy (QCAE) scale is a tool that is widely used because of its multi-dimensional assessment of ability for empathy and is currently available in many languages. The aim of the current study was to examine the psychometric properties of the Turkish version of QCAE, which evaluates cognitive and emotional empathy with its multi-dimensional structure, and to bring it into the Turkish. Methods: The study was carried out in a Turkish population of 412 healthy volunteers. Internal consistency, confirmatory factor analyses and gender comparisons of the Turkish version of the scale were performed. Results: The Turkish version of QCAE had good construct validity and reliability for the five-correlated factors model (i. e., Emotion Contagion, Proximal Responsivity, Peripheral Responsivity, Perspective Taking and Online Simulation). Temporal reliability was high with a two week test-retest intra-correlation coefficient range of 0.69–0.79. A total of 3 models were tested with confirmatory factor analyses, including the models of the original investigation. Cognitive-Affective distinction was not supported by the pattern of correlations between the factors. Conclusion: Our results support that it is appropriate to compute and interpret the 5 sub-dimensions of the Turkish version of QCAE separately and totally, but the limitations in its use in the Cognitive Empathy and Affective Empathy sub-dimensions should be heeded.
The Joint Impact of Transparency and Board Structure on Cost of Equity Capital: An Empirical Study on Companies Listed on Egyptian Stock Exchange

The paper examines the joint impact of transparency and board structure on cost of capital for a sample of firms listed on the Egyptian Stock Exchange during the period from 2010 through 2017. I predict that transparency and Board of Directors (BOD) structure has an impact of lowering cost of equity capital. The paper hypothesized that an interaction effect may exist between transparency and BOD structure in shaping their relationship with cost of capital. Results reveal that transparency has a negligible effect on cost of capital; on the contrary, evidence supports the positive impact of BOD governance on lowering cost of capital. Further, results uncover a complementary insignificant relationship between transparency and BOD structure.
Procurement planning factors influencing the quality performance of primary healthcare building facilities: A mediation effect of the firm’s business partnership

Abstract The paper reports on an assessment of the mediation effect of a firm’s business partnership on procurement planning factors influencing the quality performance of primary healthcare building facilities. A quantitative data collection approach was adopted in the study using structured questionnaires circulated to 520 respondents comprising project managers in the Nigerian construction industry. A stratified proportionate random sampling method was used for the selection of respondents which yielded 370 responses and 357 were used for analysis. Findings were that procurement planning factors influenced the quality performance of primary healthcare building facilities, and the firm’s business partnerships mediate the relationship between procurement factors and quality performance of primary healthcare building facilities. This study serves as awareness to governments and other stakeholders in the construction industry on the provision of quality primary healthcare building facilities by leveraging a firm’s business partnership as a mediating factor. Findings show that the relationship would enhance the rapid provision of quality healthcare building facilities for the growing population of Nigeria and other developing countries facing similar shortages of quality healthcare building facilities.
Tunisian Students’ Perception and Awareness of Metadiscourse Stances in Reading an Academic Text

‘Lexical Invisiblity’ or failures in perceiving metadiscourse signs could impact students’ comprehension of text, especially academic ones. In the Tunisian educational system which divides Tertiary level students into broad specialisms, teachers adopt various reading approaches accordingly to students’ needs and requirements of their professional careers. This might lead to a focus on some linguistic aspects at the expense of others, and might prevent learners from understanding the conveyed message at its fullest. The current research aims to determine to what extent Tunisian University learners (N=12) are aware of the presence of stances, while reading an academic text. Echoing Low’s (1996) and Hyland’s (2003) studies, a Think- Aloud Protocol permitted to identify students’ shortage in perceiving interactional items, such as hedges and boosters. Findings indicate that students tend to focus on the overall content and make a total abstraction of the linguistic signs of certainty and uncertainty. The investigation stresses the importance of highlighting the linguistic means that enhance the comprehension of academic texts. As overlooking interactional devices could affect students’ accurate understanding of academic texts, EFL instructors are strongly suggested to raise learners’ awareness of Metadiscourse items by teaching them explicitly and drawing their attention to them.
Large‐scale eDNA metabarcoding survey reveals marine biogeographic break and transitions over tropical north‐western Australia

Environmental DNA (eDNA) metabarcoding has demonstrated its applicability as a highly sensitive biomonitoring tool across small spatial and temporal scales in marine ecosystems. However, it has rarely been tested across large spatial scales or biogeographical barriers. Here, we scale up marine eDNA metabarcoding, test its ability to detect a major marine biogeographic break and evaluate its use as a regional biomonitoring tool in Australia.
More Than Just Zvejnieki: An Overview of Latvian Stone Age Burials

The well-known Zvejnieki cemetery, with 330 burials, is one of the largest hunter-gatherer cemeteries in northern Europe, overshadowing the more than 115 other Stone Age burials from over ten sites in Latvia. This article is a first overview of these other burials, summarizing their research history, characteristics, and assemblages. The authors discuss the problematic chronology of Latvian Stone Age burials and place them in a wider regional context. Most of the burials are hunter-gatherer burials, and a few are Corded Ware graves. This overview broadens our understanding of Latvian Stone Age burials and brings to light the diversity of hunter-fisher-gatherer mortuary practices in the eastern Baltic region.
Developing Children s Computational Thinking through Physical Computing Lessons

In this study, we designed and applied physical computing lessons for elementary 6th-grade students based on the software education guidelines in the Korean 2015 Revised National Curriculum (Ministry of Education, 2015a). The participants of this study were ten 6th-grade students of an elementary school in Gyeonggi-do province in Korea. The physical computing lessons used in this study supported the active interaction of the digital world and the physical world by constructing a physical model using specific media, and controlling it with a program. In order to understand the changes in the students’ computational thinking after the class, we analyzed these changes in terms of computational concept, computational practice, and computational perception. Research has shown that physical computing lessons materialize students’ computational concepts through computational practices, and improve their computational perspectives through the use of authentic contexts. We expect that the physical computing lessons and analysis tools developed through this study will provide educational implications for future software education.
The major life events taxonomy: Social readjustment, social media information sharing, and online network separation during times of life transition

When people experience major life changes, this often impacts their self‐presentation, networks, and online behavior in substantial ways. To effectively study major life transitions and events, we surveyed a large U.S. sample (n = 554) to create the Major Life Events Taxonomy, a list of 121 life events in 12 categories. We then applied this taxonomy to a second large U.S. survey sample (n = 775) to understand on average how much social readjustment each event required, how likely each event was to be shared on social media with different types of audiences, and how much online network separation each involved. We found that social readjustment is positively correlated with sharing on social media, with both broad audiences and close ties as well as in online spaces separate from one's network of known ties. Some life transitions involve high levels of sharing with both separate audiences and broad audiences on social media, providing evidence for what previous research has called social media as social transition machinery. Researchers can use the Major Life Events Taxonomy to examine how people's life transition experiences relate to their behaviors, technology use, and health and well‐being outcomes.
Toxic metals bioremediation potentials of Paenibacillus sp. strain SEM1 and Morganella sp. strain WEM7 isolated from Enyigba Pb–Zn mining site, Ebonyi State Nigeria

Abstract Heavy metal contamination is a serious environmental and ecological problem currently facing many countries. Discovering a novel biological means of detoxifying environments contaminated with these heavy metals is an urgent necessity. More so, an efficient bio-remediating agent from biological sources would be cost effective, climate change friendly and easily accessible with less negative effects on the environment. We report a novel study on heavy metals’ tolerant and bioremediation potentials of Penibacills sp. Strain SEM1 and Morganella sp. Strain WEM7 isolated from Enyigba Pb–Zn mining site, Ebonyi State, Nigeria. The result revealed that the bacteria isolates optimally thrived in media containing 5–15% of sodium chloride. The SEM1 showed capacity to tolerate lead, mercury and nickel up to 10,000 mg/l, up to 1400 mg/l for cadmium and up to 2500 mg/l each of copper and zinc. Additionally, WEM7 resisted zinc, copper and nickel up to 2500 mg/kg, mercury and cadmium up to 630 and 700 mg/kg respectively and more than 10,000 mg/kg of lead in both solid and liquid media. The 16S rRNA gene assay and phenotypic physiognomies of SEM1 and WEM7 strains fit in the genus Paenibacillus and Morganella respectively. The trend of heavy metals removal by SEM1 is as follows: Ni > Pb > Hg > Cu > Zn > Cd (97.62, 96.84, 90, 86.36, 84.85, 70%) and that of WEM7: Cu > Ni > Pb > Hg > Zn > Cd (100, 98.64, 97.48, 93.33, 80.85, 68.42%). Our investigation revealed that the isolates, SEM1 and WEM7 are moderately halophilic, metalophiles and could provide exceptional novel tool for mercury, lead, cadmium, nickel, copper and zinc bioremediation in contaminated environments.
Influence of sugar sources and blended must on physico-chemical and sensory characteristics of Nagpur mandarin wine

An investigation on “Effect of different sugar sources and blended must on physico-chemical and sensory characteristics of Nagpur mandarin wine” was conducted at Post-Harvest Technology Laboratory, Department of Fruit Science, Dr. PDKV, Akola during the academic year 2017-18 with the objectives of to study the chemical changes and sensory qualities of blended wine prepared from Nagpur mandarin and to find out the suitable combinations of sugar sources and blended wine prepared from Nagpur mandarin. The experiment was carried out with three sugar sources (Cane sugar, Jaggery and Honey) and Nagpur mandarin juice was blended with coloured grape and pomegranate juices in different proportion and framed in Factorial Completely Randomized Design with three replications and fifteenth treatments. The wine of each bottle was transferred into 200 ml fresh sterile glass bottles and sealed air-tight with crown caps, keeping 0.7 cm head-space. The sealed wine bottles were subjected for pasteurization in water bath at 65 °C for 20 minutes. After cooling, the wine bottles were labeled with respective treatment name and left for storage of 3 months. From the finding it was observed that, there was decrease in ethyl alcohol, TSS and total phenol content of Nagpur mandarin wine irrespective of storage period. Whereas, pH content of Nagpur mandarin wine increased with the advancement of storage period of 3 months. Maximum ethyl alcohol, pH and total phenol and minimum TSS was observed when Nagpur mandarin wine prepared with Honey as sugar source and blended with mandarin juice and coloured grape juice with 80:20 ratio. Similarly, the Nagpur mandarin wine prepared with Honey as sugar source and blended with mandarin juice and coloured grape juice with 80:20 ratio secured the highest score for colour, flavour, taste, appearance, astringency and overall acceptability as compared to other treatment.
Determinants of Consumers’ Willingness to Buy Counterfeit Luxury Products: An Empirical Test of Linear and Inverted U-Shaped Relationship

The proliferation of counterfeit luxury goods poses a great threat to the sustainable development of the luxury goods industry; it also disturbs the order of economic development, causes the aggravation of environmental pollution, and is contrary to the principle of global sustainable development. How to effectively weaken consumers’ willingness to buy counterfeit luxury products has become a focal issue. This research explores the impact of value consciousness, social risk perception, and face consciousness on the purchase intention of counterfeit luxury. In addition, this study explores the different mediating roles played by attitude. The results show that value consciousness has a significant positive impact on the counterfeit luxury purchase intention through the full mediation of attitudes. Perceived social risk not only exerts a direct negative impact on the purchase intention of counterfeit luxury products but can also indirectly influence intention through the partial mediation of attitudes. Besides, there is an inverted U-shaped relationship between face consciousness and counterfeit luxury purchase intention, and attitudes play a partially mediating role in this inverted U-shaped path. This research also has certain management implications for the government and luxury products companies to formulate relevant policies and marketing strategies to curb consumers’ willingness to purchase counterfeit luxury products.
Assessment of the Possibilities of Using Cross-Linked Polyacrylamide (Agro Hydrogel) and Preparations with Biostimulation in Building the Quality Potential of Newly Planted Apple Trees

The research was carried out in a commercial apple orchard in southeastern Poland. The aim of the research was to evaluate the effect of fertilizer with biostimulation and humic acids with algae extracts and agrogel on the reception and growth of newly planted maiden apple trees of the ‘Gala Must’ variety. One-year-old budwoods were planted annually on the site where fruit trees had grown for 20 years. For the purpose of the experiment, old trees were grubbed up every year in autumn. The experiment assessed the growth and quality of apple trees in the fall of the first year after planting them permanently using a biostimulator in the form of fertilizer and agrogel. On the basis of 3-year studies, it was shown that the application of the assessed preparations had a positive effect on the quality parameters of the trees. The experiment showed the positive effect of the preparation with biostimulation on the best growth and quality parameters every year, which was confirmed by the multidimensional cluster analysis. The fact that the use of agrogel significantly modified the height of the evaluated apple trees in the second year of the study, when lower amounts of rainfall were recorded, is particularly noteworthy.
MAST-RT0 solution of the incompressible Navier–Stokes equations in 3D complex domains

A new numerical methodology to solve the 3D Navier-Stokes equations for incompressible fluids within complex boundaries and unstructured body-fitted tetrahedral mesh is presented and validated with three literature and one real-case tests. We apply a fractional time step procedure where a predictor and a corrector problem are sequentially solved. The predictor step is solved applying the MAST (Marching in Space and Time) procedure, which explicitly handles the non-linear terms in the momentum equations, allowing numerical stability for Courant number greater than one. Correction steps are solved by a Mixed Hybrid Finite Elements discretization that assumes positive distances among tetrahedrons circumcentres. In 3D problems, non-Delaunay meshes are provided by most of the mesh generators. To maintain good matrix properties for non-Delaunay meshes, a continuity equation is integrated over each tetrahedron, but the momentum equations are integrated over clusters of tetrahedrons, such that each external face shared by two clusters belongs to two tetrahedrons whose circumcentres have positive distance. A numerical procedure is proposed to compute the velocities inside clusters with more than one tetrahedron. Model preserves mass balance at the machine error and there is no need to compute pressure at each time iteration, but only at target simulation times.
The Puzzle of Immunosuppressive Drugs

Kidney transplantation has become the preferred treatment option in end-stage chronic renal failure as it provides significant improvements over dialysis in terms of both quality and duration of life. Even after several randomized studies conducted in the last 20 years, the combination of CNI, MMF, and steroids continues to be considered the gold standard for kidney transplantation. However, novel molecules aimed at minimizing renal and cardiovascular toxicity, particularly with CNI sparing, are being identified. The present review assesses various such molecules available currently and briefly discusses the existing combination strategies and novel perspectives for the redesigning of protocols based on our novel therapeutic arsenal.
Can Team-Sport Athletes Accurately Run at Submaximal Sprinting Speeds? Implications for Rehabilitation and Warm-Up Protocols

Abstract Darrall-Jones, J, Roe, G, Cremen, E, and Jones, B. Can team-sport athletes accurately run at submaximal sprinting speeds? Implications for rehabilitation and warm-up protocols. J Strength Cond Res 36(8): 2218–2222, 2022—The aim of this study is to examine the ability of team-sport athletes to accurately run at a range of submaximal sprint velocities (60–90% maximal velocity; Vmax) under verbal instruction without any objective feedback. Twelve professional male rugby union players (age 19.7 ± 0.9 years, body mass 98.3 ± 13.9 kg, height 184.0 ± 7.5 cm) were verbally instructed to complete three 40-m sprints at each of 60, 70, 80, and 90% of Vmax in a randomized order. Percentage Vmax achieved during each sprint was compared with criterion velocities calculated from Vmax testing undertaken a week prior. Players underestimated (ran faster) their sprint velocity when asked to run at 60% (very large to extremely large mean bias, 23%; range, 57–88% Vmax), 70% (large to very large, 11%; 67–93% Vmax), and 80% (small, 2%; 71–91% Vmax) of their Vmax, whereas overestimated (ran slower) their sprint velocity when asked to run at 90% Vmax (moderate, −4%; 77–95% Vmax). Team sport players may require objective feedback when performing submaximal sprinting to ensure that velocities achieved are similar to those prescribed. This may be particularly important where graded exposure to maximum velocities is required, for example during rehabilitation or warm-ups.
Controllability problems for the heat equation on a half-axis with a bounded control in the Neumann boundary condition

In the paper, the problems of controllability and approximate controllability are studied for the control system \begin{document}$ w_t = w_{xx} $\end{document} , \begin{document}$ w_x(0,\cdot) = u $\end{document} , \begin{document}$ x>0 $\end{document} , \begin{document}$ t\in(0,T) $\end{document} , where \begin{document}$ u\in L^\infty(0,T) $\end{document} is a control. It is proved that each initial state of the system is approximately controllable to each target state in a given time \begin{document}$ T $\end{document} . A necessary and sufficient condition for controllability in a given time \begin{document}$ T $\end{document} is obtained in terms of solvability of a Markov power moment problem. It is also shown that there is no initial state which is null-controllable in a given time \begin{document}$ T $\end{document} . Orthogonal bases are constructed in \begin{document}$ H^1 $\end{document} and \begin{document}$ H_1 $\end{document} . Using these bases, numerical solutions to the approximate controllability problem are obtained. The results are illustrated by examples.
