Short Communication: The higher laccase enzyme producer, Cerrena sp. BMd.TA.1, isolated from Gunung Rinjani National Park, West Nusa Tenggara, Indonesia

Faulina SA, Irfani M, Falah S, Hidayat A, Iswanto AH. 2020. Short Communication: The higher laccase enzyme producer, Cerrena sp. BMd. TA.1, isolated from Gunung Rinjani National Park, West Nusa Tenggara, Indonesia. Biodiversitas 21: 3837-3842. Lies in the Wallace line, Gunung Rinjani National Park (GRNP) offers unique biodiversity, fungi included. Fungal enzymes have been unceasingly searched and studied for various applications, particularly for biodegradation. Fungal laccase enzyme showed prospective environmental-friendly approach in treating industrial effluent, remazol brilliant blue R (RBBR) which is used as a synthetic dye. This study aimed to explore the laccase-producing fungi from the GNRP, as well as investigate their ability in decolorizing RBBR. The study discovered that the most prospective fungi isolate, molecularly identified as Cerrena sp. BMd.TA.1, produced a high level of laccase (> 2300 U mL) and manganese peroxidase (MnP, 300 U mL). In the application of this isolate, the laccase showed as predominant enzyme in RBBR decolorization process and the RBBR could be decolorized more than 80% at 24 h reaction. It suggested that Cerrena sp BMd.TA.1 isolate is highly potential as laccase enzyme producer and may be considered for further investigations in its applications for biodegradation, especially of dyes effluent.
Information leakage in the football transfer market

ABSTRACT Research question: Previous studies have examined the impact of various sports-related events on the stock exchange; however, the impact of information leakage about players’ transfer on the stock price of football clubs is yet to be explored. This study seeks to bridge the gap by investigating whether abnormal returns occur at well-known European football clubs before the announcement of the transfer. Research method: Using an event study methodology, the effect of 272 player purchases between 2015 and 2019 were analysed. The abnormal returns were estimated by applying a partial adjustment model containing the autoregressive conditional heteroscedasticity specification; then, the typical runs of cumulative abnormal returns were identified. Results and findings: In the vast majority of cases, the stock reacted to the announcement; moreover, in two-thirds of the transactions, information leakage was also established. Because the small shareholders of football clubs are, presumably, emotional investors, rather than rational ones, most of the transfers affect share prices even before the announcement; this is potentially because the acquisition of a star player strengthens both their commitment to the club and belief in its sporting success. Implications: This study provides some managerial implications for football club owners, managers, and regulators. Although there is information leakage, it is not of such a magnitude as to require the regulation of the stock market and bulk trading. It can be stated that investors were most likely to receive extra profit as a reward for their committed supporter attitude, and this is by no means a market failure.
Sehgal index and its comparison with Mentzer's index and Green and King index in assessment of peripheral blood smear with marked anisopoikilocytosis

Background: Mild microcytic hypochromic anaemias due to iron deficiency (IDA) and beta thalassemia trait(β-TT) continue to be a cause of significant burden to the society, particularly in the poorer developing countries. The objective of the present study was to study the RBC based indices in patients of marked anisopoikilocytosis in determining the etiology of it, to standardize few automated red cell parameters, and also objective grading of RBC morphology on peripheral smear and interpreting its utility in indicating a diagnosis. Also, to establish a relation between value of RBC indices with that of degree of anisocytosis.Methods: A total of 500 patients diagnosed with mild microcytic hypochromic anaemia on complete blood count and peripheral blood film were included in the study. Hb, RBC count, MCV, MCH and RDW obtained from the electronic cell counter were used to calculate discrimination indices by various mathematical formulae. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden’s index (YI) were calculated.Results: Green and King index demonstrated the lowest sensitivity of 70.51%. Mentzer index demonstrated the highest specificity of 96.80%. The highest and lowest PPV were found for Mentzer index (97.09%) and Sehgal index (92.81%) respectively. Sehgal’s index demonstrated the highest NPV of 95.96% and lowest NPV was exhibited by G and K (87.9%). The highest and the lowest values for Youden’s index were shown by Sehgal’s index (87.82%) and G and K index (68.47%). Conclusions: Sehgal’s index followed by Mentzer index are highly sensitive and reasonably specific in differentiating β-TT from IDA and none of the indices is 100% sensitive and specific. Though HbA2 estimation is the gold standard for diagnosing β-TT, in developing countries, Sehgal index followed by Mentzer et al, index can be used to screen mild microcytic hypochromic anaemia cases to eliminate as many false positive cases as possible to reduce the financial cost.
On the Procedure of Draught Rate Assessment in Indoor Spaces

The objective of the paper is to demonstrate the importance of the unsteady Computational Fluid Dynamics (CFD) simulations and long-term measurements for the reliable assessment of thermal comfort indoors, for proper categorization of the indoor thermal environment and for identifying the reasons for complaints due to draught discomfort. Numerical simulations and experimental measurements were applied in combination to study ventilation in a field laboratory, a university classroom with a controlled indoor environment. Strong unsteadiness of the airflow was registered both in the unsteady RANS results and the real-scale long-term velocity data measured with thermo anemometer. Low-frequency high-amplitude velocity fluctuations observed lead to substantial time variation of the draught rate. In case of categorization of a thermal environment, the point measurements or steady-state RANS computations would lead to wrong conclusions as well as they cannot be used for identification of the reasons for people’s complaints due to draught discomfort if strong unsteadiness of the airflow exists. It is demonstrated that the length of the time interval for draught rate (DR) assessment may not be universal if low-frequency high-amplitude pulsations are present in the room airflow.
Valuation of Weed Control Methods by using Inter Row Rotary Weeder in Sugarcane Crop

Background: Weeds are one of major threats to crop yield and quality. Weeds compete with cane crop and reduce the yield significantly in a very short period. Planned use of all available farm resources leads to integrated control strategy. The current study aimed to study the use of inter row rotary weeder for integrated weeds management to control population dynamics of weeds in sugarcane crop. The objective of experiment is to find out economical, feasible and easy to use approach to minimize the weed density below the threshold level in sugarcane crop and to minimize the use of chemicals for weeds control to promote organic farming. Method: In this research experiment, at Sugarcane Research Institute, Faisalabad during 2017 and 2018, the treatment includes viz. Application od Click (atrazine and acetochlor) @ 3.75 Liter per hectare as Pre-emergence, Ametryn + Atrazine 80 W.P @ 2.50 kg per hectare as post-emergence, Machanical Inter-culture with Rotary weeder and cultivator plough and earthing up. These treatments in different combinations were compared with control. Results: The application of Pre-emergence weedicide Click (atrazine and acetochlor) @ 3.75 Liter per hectare + Inter culture with Rotary weeder 50 days after planting (DAP) + Inter culture with cultivator plough before earthing up (100 DAP) produced significantly higher cane yield of 105 t. ha-1 and highest net benefits per hectare of Rs. 156250/-. The lowest cane yield of 70 t. ha-1 was noted from the experimental units with Weedy check / control. If farmers use this approach, the use of post emergence weedicides will be minimized and will encourage organic farming with safe and healthy environment.
Influence of gender on static balance in healthy community dwelling elderly: a comparison using posturography

Background: Background and need of study- Influence of gender on balance is still controversial. Previous researchers have done studies using traditional methods. These methods may fail to detect subtle changes in balance difference. A tool like posturography which is highly specific may help to for accurate assessment and hence precise conclusion. Aim was to compare balance scores of male and female elderly using modified Clinical Test of Sensory Interaction on Balance (CTSIB). Methods: There were 56 healthy elderly ambulating without an assistive device and free from any neurological and orthopedic problems were assessed for their balance abilities using mCTSIB of balance master(standing on firm surface with eyes open, with eyes closed, standing on foam surface with eyes open and with eyes closed). Sway velocity was assessed using Unpaired t test.Results: There was a no significant difference in scores of modified CTSIB between male and female elderly ( p value>0.005). Conclusions: Gender has no effect on static balance abilities between male and female elderly while performing modified clinical test of sensory interaction on balance.
Impact of website design features on experiential value and patronage intention toward online mass customization sites

PurposeTo examine the relationships among website design features, consumer experience responses and patronage intention toward online mass customization (OMC) apparel websites.Design/methodology/approachA total of 312 useable online surveys were obtained from Mainland China consumers. Multi-item scales were adopted to measure eight constructs: visual design; information quality; entertainment, aesthetic, educational, escapist experiences; flow; and patronage intention. Structural equation modeling (SEM) was conducted to determine factor structures and to test the hypothesized relationships among website design features, 4Es (entertainment, aesthetic, educational and escapist experiences), flow and consequent purchase intention toward OMC apparel websites.FindingsAll hypotheses, but one, were supported. OMC website visual design; information quality; and entertainment, aesthetic and educational experiences had a positive effect on consumer patronage intention.Research limitations/implicationsLimitations include using a sample of consumers from major cities in China; results cannot be generalized to all Chinese consumers. Websites were not actively navigated. Additionally, the present study examined only two dimensions of OMC website quality, visual design and information quality; more tangible and specific features could be considered in future research.Practical implicationsThe findings provide website designers and marketers with insights into experiences that may lead to an increase in patronage intention toward OMC websites.Originality/valueThe study provides evidence that flow helps explain the impact of experiential value (i.e. 4Es) from website design features on patronage intention.
Antioxidant Response and Oxidative Stress in the Respiratory Tree of Sea Cucumber (Apostichopus japonicus) Following Exposure to Crude Oil and Chemical Dispersant

Sea cucumber (Apostichopus japonicus) is mainly cultured in the coastal zone, where it is easily threatened by accidental oil spills. Chemical dispersant is one of the efficient oil spill responses for mitigating the overall environmental damage of oil spills. However, the impact of crude oil and chemical dispersants on sea cucumber is less well known. Hence, the present study focused on exploring the antioxidant response and oxidative stress in the respiratory tree of sea cucumber following exposure to GM-2 chemical dispersant (DISP), water-accommodated fractions (WAF), and chemically enhanced WAF (CEWAF) of Oman crude oil for 24 h. Results manifested that WAF exposure caused a significant increase in the reactive oxygen species (ROS) level (5.29 ± 0.30 AU·mgprot−1), and the effect was much more obvious in CEWAF treatment (5.73 ± 0.16 AU·mgprot−1). Total antioxidant capacity (T-AOC), as an important biomarker of the antioxidant defense capacity, showed an increasing trend following WAF exposure (0.95 ± 0.12 U·mgprot−1) while a significant reduction in T-AOC was observed following CEWAF exposure (0.23 ± 0.13 U·mgprot−1). Moreover, we also evaluated the oxidative damage of the macromolecules (DNA, protein, and lipid), and our results revealed that the presence of chemical dispersant enhanced oxidative damage caused by crude oil to sea cucumber.
On the performance of the variance ratio unit root tests with flexible Fourier form

This article introduces a new unit root test that combines the variance ratio framework with the Flexible Fourier Form under the generalized least squares detrending mechanism. The advantage of the proposed method against its alternatives can be listed as: (1) it suggests a non-parametric procedure that does not require any parametric or semi-parametric model to remove serial correlation in the innovation process; (2) it can reasonably adapt itself to deal with the multiple structural breaks with various functional specifications. In the simulation exercises, we show that the proposed method exhibits satisfactory performance in the size and size-adjusted power analysis.
Does Credit Influence Fertilizer Intensification in Rice Farming? Empirical Evidence from Côte D’Ivoire

In Côte d’Ivoire, the use of fertilizers in rice farming still remains low. Credit constraints have been frequently reported as the main reason hampering rice farmers from reversing this situation. However, there is no empirical evidence on the link between rice farmers’ access to credit (AC) and fertilizer intensification (FI). This article examines this issue by using a sample of 600 rice farmers randomly selected in seven rice areas. Data are analyzed by the IV-Probit and IV-Tobit models. The results reveal that FI and AC reciprocally influence each other, implying that they are endogenous. An increase of credit by XOF 100 could increase the quantity of fertilizer used by 2.70 kg, all other things being equal. Moreover, FI and AC are strongly influenced by some socio-economic, rice farm, and institutional factors. Policymakers should take actions to facilitate rice farmers’ access to credit and subsidized fertilizers. Other relevant explanatory variables should be considered in rice farming development policies. By providing empirical evidence of the link between rice farmers’ access to credit and fertilizer intensification in Côte d’Ivoire, this paper contributes to the agricultural finance literature.
A Scoping Review of Relationship-based Training Programs for Early Childhood Educators.

Aim and Background: An increasing rise in childcare attendance has resulted in children spending additional time with non-parental caregivers, such as Early Childhood Educators (ECE’s). Strong relationships between children and ECE’s are important as these relationships impact on children’s development. Relationship-based training programs offered by occupational therapists, are one way of supporting educators with building and maintaining positive relationships with children in their care. This scoping review aimed to provide a summary of the features and outcomes of relationship-based training with ECE’s. Methods: After a systematic search and following PRISMA guidelines, a total of 26 studies were included. Results: A wide range of relationship-based training programs were described, with multiple components and group-based training, as well as individual consultation/coaching reported. All included studies reported that relationship-based training programs resulted in positive outcomes for children and/or educators. This review provides a foundation for designing relationship-based training programs for ECE’s.
On the Impact of COVID-19-Related Uncertainty

COVID-19 has generated a substantial increase in the level of economic policy uncertainty (EPU) around the World. Recent empirical investigations suggest that the COVID-19 has played a key role in amplifying the overall level of political uncertainty. In Italy, where anti-COVID-19 measures were implemented with some delay and were badly communicated, EPU rose dramatically. We examine the implications of rising COVID-19-related uncertainty for company revenues, gross operating margin and employment in 16 different Italian sectors. Our findings indicate construction, education, manufacturing activities and hospitality as the most hit sectors, with an average short-term drop in company revenues of around 4% in annual terms and a recovery time of almost two years. Thus, COVID-19-related uncertainty is found to be a significant business cycle driver.
Blockchain-based food supply chain traceability: a case study in the dairy sector

ABSTRACT Traceability has become a critical element in supply chain management, particularly in safety-sensitive sectors like food, pharmaceuticals, etc. Upstream (manufacturers, producers, etc.) and downstream (distributors, wholesalers, etc.) supply chain members need to store and handle traceability-related information for providing proof of regulatory compliance to both state authorities and more demanding customers. Consumers also place high expectations on food supply chains (FSC) with specific emphasis on facets related to safety. However, the complexity of modern FSC networks and their fragmentation act as barriers for the development of sound traceability mechanisms. In this paper a distributed trustless and secure architecture for FSC traceability is developed and tested. For assessing the feasibility of the proposed approach, a food traceability case study from a dairy company is presented. The applicability of the model is further illustrated by the development of fully functional smart contracts and a local private blockchain. Moreover, the various links between the proposed blockchain-based model and its managerial implications are presented. The overall benefits of the proposed model are discussed along with fruitful areas for future research. The results are of significant value to both practitioners and researchers.
Does Audit Committee Quality Mediate Determinants of Intellectual Capital Disclosure?

This study investigates the direct and indirect effects, mediated by audit committee quality, of managerial ownership, institutional ownership, and profitability on intellectual capital (IC) disclosure. The object observed of this study is companies listed on the Indonesia Stock Exchange (IDX) in the 2014-2018 period that are classified as high intellectual capital-intensive industries. Based on the sampling method, purposive sampling, 51 companies were selected as samples. This study used path analysis techniques with IBM SPSS version 25 to study the direct and indirect influences of managerial ownership, institutional ownership, and profitability toward IC disclosure. The results of this study show that managerial ownership, profitability and audit committee quality have a significant positive effect on IC disclosure whereas institutional ownership has significant negative effect on IC disclosure. This study also provides empirical evidence, supported by the sobel test, that the audit committee quality is able to mediate the effect of institutional ownership and profitability on IC disclosure. However, the audit committee quality is not able to mediate the effect of managerial ownership on IC disclosure. These findings develop and strengthen the results of prior studies related to the implementation of signaling theory and agency theory in devoting more understanding about IC disclosure.
Whale optimization algorithm based on nonlinear convergence factor and chaotic inertial weight

The whale optimization algorithm (WOA) is a new biological meta‐heuristic algorithm based on the social hunting behaviors of humpback whales. However, it can easily fall into a local optimum when solving complex problems and exhibits slow convergence speed and poor exploration. This study proposed three improved versions of the WOA based on the concepts of chaos initialization, nonlinear convergence factor, and chaotic inertial weight to enhance its exploration abilities. These properties were employed to improve the population diversity and maintain the balance between exploration and exploitation. The performance of the best version was compared with those of moth‐flame optimization, firefly algorithm, particle swarm optimization, gray wolf optimizer, flower pollination algorithm, original WOA, and two recently proposed hybrid WOA through 19 benchmark functions. Experimental results indicated that the proposed algorithms exhibit better performance in terms of complexity and convergence speed.
Interorganizational learning, green knowledge integration capability and green innovation

PurposeAlthough interorganizational learning has attracted substantial attention, research about its effects on green innovation is still rare. Combining theories of organizational learning and absorptive capacity, this study explores the relationships among interorganizational learning, green knowledge integration capability (GKIC) and green innovation (GI), and analyzes the moderating role of green absorptive capacity (GAC). Based on resource-based and ambidexterity theories, this study focuses on vertical exploitative (VEL) and lateral explorative learning (LEL). This study expands the research of GI by proposing two different interorganizational learning mechanisms and uncovering the intricate relationship between them and GI.Design/methodology/approachBased on a sample of 203 Chinese manufacturing firms, the authors used a hierarchical regression analysis and bootstrap method to test the theoretical framework and research hypotheses of this paper.FindingsResults show that VEL and LEL have positive effects on GI. GKIC partially mediates the relationship between VEL and GI and completely mediates the relationship between LEL and GI. Moreover, GAC plays a moderating role between LEL and GKIC and moderates the effect of LEL on GI via GKIC, such that the effect is stronger when GAC increases. However, it does not moderate the relationship between VEL and GKIC.Originality/valueFirst, founded on resource-based and ambidexterity theories, this study considers two dimensions of interorganizational learning, VEL and LEL. Second, by testing the mediating role of GKIC, the authors provide a theoretical lens to understand the relationship between interorganizational learning and GI. Third, by examining boundary conditions of GAC, the authors enrich organizational learning and absorptive capacity theory in the context of green development.
