Stock prices, uncertainty and risks: Evidence from developing and advanced economies

This paper studies the relationship between stock prices and three types of uncertainty: economic policy uncertainty, stock market volatility, and geopolitical risks. In particular, our aim is to determine whether these forms of uncertainty play the same role in developed and developing countries. With this purpose, we take Spain and Brazil as representative cases. In order to provide new insights into the abovementioned relationship, a cointegration approach is applied, specifically an ARDL model, using monthly data from the period January 2006-December 2019 for a series of financial and macroeconomic variables. The results obtained reveal that there is no uniform effect of uncertainty in stock markets of developing and developed countries. First, in Spain, there is a high perception of uncertainty in economic policy and stock market volatility, which impact negatively in share prices, both in the short and long term. Regarding Brazil, the global uncertainty in the stock markets has effects on share prices, in both time horizons. By contrast, geopolitical risks do not show any significant impact on Brazilian and Spanish share returns.
NetBERT: A Pre-trained Language Representation Model for Computer Networking

Obtaining accurate information about products in a fast and efficient way is becoming increasingly important at Cisco as the related documentation rapidly grows. Thanks to recent progress in natural language processing (NLP), extracting valuable information from general domain documents has gained in popularity, and deep learning has boosted the development of effective text mining systems. However, directly applying the advancements in NLP to domain-specific documentation might yield unsatisfactory results due to a word distribution shift from general domain language to domain-specific language. Hence, this thesis aims to determine if a large language model pre-trained on domain-specific (computer networking) text corpora improves performance over the same model pre-trained exclusively on general domain text, when evaluated on in-domain text mining tasks. To this end, we introduce NetBERT (Bidirectional Encoder Representations from Transformers for Computer Networking), a domain-specific language representation model based on BERT (Devlin et al., 2018) and pre-trained on large-scale computer networking corpora. Through several extrinsic and intrinsic evaluations, we compare the performance of our novel model against the general-domain BERT. We demonstrate clear improvements over BERT on the following two representative text mining tasks: networking text classification (0.9% F1 improvement) and networking information retrieval (12.3% improvement on a custom retrieval score). Additional experiments on word similarity and word analogy tend to show that NetBERT capture more meaningful semantic properties and relations between networking concepts than BERT does. We conclude that pre-training BERT on computer networking corpora helps it understand more accurately domain-related text.
Orthopterans (Insecta: Orthoptera) of conservation value in the Eurasian Eagle Owl Bubo bubo food in Bulgaria

Three species of Bush-crickets (Orthoptera) of conservation value or poorly known were found in the Eurasian Eagle Owl food in southeastern Bulgaria. Their localities are new country records and two of them cover Natura 2000 SCI zones. The repeated predation on Bradyporus macrogaster in UTM square MG99 confirms the potential of this area for a new Natura 2000 site.
Insulin Resistance in Pediatric Systemic Lupus Erythematosus and Rheumatoid Arthritis

Background: Childhood rheumatologic disorders are multisystem diseases characterized by inflammation, damage, and/or pain of the joints, and connective tissues. Aim: This study aimed to detect the presence of insulin resistance (IR) in pediatric patients with systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA) which can lead to the development of diabetes mellitus. Subjects and Methods: This case-control study was performed on 60 SLE, 60 RA patients, and 60 healthy subjects as a control group. All subjects were subjected to detailed history taking, physical examination, and laboratory investigations including determination of fasting blood glucose (FBG), total cholesterol, triglyceride (TG), HDL, LDL, and fasting insulin. Homeostatic model assessment of insulin resistance (HOMA IR) was calculated. Results: There was no significant difference in the age, and FBG in the three studied groups but there was a significant difference as regard platelets counts, hemoglobin, ESR, CRP, TG, HDL, fasting insulin levels, and HOMA IR. There is no significant difference between the SLE, and RA in disease duration, ESR, CRP, HDL, LDL, triglyceride, cholesterol, fasting blood glucose, fasting insulin levels, and HOMA IR. There were significant positive correlations between HOMA IR with patients’ BMI, ESR, CRP, TG, FBG, and fasting insulin levels in both SLE and RA groups. Conclusions: SLE, and RA patients had a higher insulin resistance than age-matched healthy controls which can lead to the development of type 2 diabetes mellitus. HOMA IR had positive correlations with BMI, TG, FBG, and fasting insulin levels in both SLE and RA groups.

Association of the BellaGel® Breast Implant Scandal with the Poly Implant Prothèse Fraud: A Review of Literatures

Marketing defective breast implants (BellaGel®; HansBiomed Co. Ltd., Seoul, Korea) despite knowledge or reasonable cause to believe that the device is defective has been recently found in Korea, thus termed as the BellaGel® breast implant scandal. Evidence suggests that the HansBiomed Co. Ltd. previously participated in the Poly Implant Prothèse (PIP) fraud in Europe. Based on the fact that the manufacturer was previously involved in the PIP fraud, it would be mandatory to consider long-term safety outcomes of victims of the BellaGel® breast implant scandal.
Comparison of STONE score with Guy’s stone score as a tool to predict stone clearance rates in patients undergoing percutaneous nephrolithotomy: a single center study

Background: We aimed to compare the Guy’s stone score and STONE nephrolithometry score and assess their predictive accuracy for percutaneous nephrolithotomy (PCNL) outcomes. Methods: A total of 100 patients, who underwent PCNL between Jan 2018 and Dec 2018 were included in the study. All patients were evaluated with computerized tomography (CT) scan preoperatively and scores were calculated. Patient demographic characteristics, intraoperative and postoperative variable were evaluated. The relationship between the Guy’s and STONE scores, and their prediction for postoperative stone-free status, complications were compared. Results: The mean Guy’s score was 2.04±1.01, and the mean STONE score was 8.0+1.7. The mean operative time was 101.9+41 minutes and the mean blood loss was 170+113ml. The complication rate in our study was found to be 32%, majority were grade 1-2. Both scoring systems showed positive correlation with stone burden, operating time and blood loss. The overall stone free rate was 72% and both the GSS and STONE score were significantly associated with success of the procedure. Conclusions: Both Guy’s and STONE scoring systems are equally effective in predicting stone-free status.
Measurement of continuous-phase mass transfer coefficient at droplet surface in liquid-liquid mixing vessel by chemical reaction method.

The continuous-phase mass transfer volumetric coefficient kLa in a liquid-liquid mixing vessel was measured by using the hydrolysis reaction of both n-amyl and n-hexyl acetates with sodium hydroxide. Droplet diameter was also observed by using a videorecorder via a microscope during the reaction period, allowing the continuous-phase mass transfer coefficient, kL, to be determined. The coefficient obtained was 2–5 times larger than that obtained from the correlation by Calderbank–MooYoung. Dimensionless correlation of the mass transfer coefficient with the droplet diameter and the power input per unit volume was confirmed experimentally to be close to that for the solid suspension system.

Performance Analysis of Device to Device Communications Overlaying/Underlaying Cellular Network

Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipath fading. Then, simulation results of the exact formulas and previously respected approximate formulas are compared in MATLAB for both underlay and overlay scenarios. It is shown that the approximate formula in underlay scenario is a good estimate for exact one while approximate formula for overlaying scenario is a good approximation when the average distance between the transmit/receive nodes of D2D pair is less than half of the maximum distance between these nodes or variance of multipath fading is greater than 1.5. In addition, the probability density functions of Signal to Interference plus Noise Ratio (SINR) for underlay and overlay scenarios are found. Moreover, a new scenario is proposed which jointly considers overlay and underlay scenarios. Furthermore, exact and approximate formulas for outage probability and throughput of D2D users in the proposed scenario are derived. Finally, these formulas are compared to underlay and overlay scenarios in three special cases, low, moderate and high traffic loads.
Information Technology Capability and Firm Performance: The Role of Strategic Orientation

A key strand of IT business value research is concerned with the measurement of IT capability of firms and the impact of IT capability on the accounting-based measures of firm performance. Previous empirical studies examining this relationship in the context of developed economies have reported mixed results, and there is a dearth of studies in the context of emerging economies. In this study, we seek to employ archival data from the emerging economy context of India, and replicate the findings from the earlier studies, in order to examine the existing theory. We also propose to extend the existing theory by incorporating the role of strategic orientation (indicated by the Miles and Snow strategy types) of the firms while examining the impact of IT capability on firm performance. Thus, the results of this study offer possibilities of both theoretical and practical implications.
Antibacterial Activities of Allium Sativum (Garlic) Extracts Against Staphylococcus Aureus and Escherichia Coli

The search for using natural product and plant compounds as antimicrobial agents has been increased in the last decades. This study aimed of evaluate the antibacterial effects of Allium Sativum (garlic) extracts against Staphylococcus aureus and Escherichia coli. The garlic were peel and grinded until it turned into puree form. The garlic extracts were homogenized and mixed with distilled water to obtain four dilution concentration; 25% garlic extract, 50% garlic extract, 75% garlic extract and 100% garlic extract. The extract was tested against S. aureus and E. coli. All garlic extracts concentration demonstrated varying degrees of antimicrobial activities against both of bacteria. However, the zones of inhibition obtained using 100% of garlic extract were larger compared with those of lower garlic concentrations against both S. aureus and E. coli. The results suggest that garlic extract highly active antimicrobial components. Further investigation is warranted to improve the extraction methods and to identify the antibacterial activity of garlic extracts against different bacterial species.
The physico-mechanical properties of concrete with red-mud at high temperatures

Reuse of treated waste can provide significant environmental, social and economic benefits. It is necessary to use it in the right places while keeping the properties of the waste in mind. Aluminum-rich wastes such as red mud derived from bauxite may be used in places exposed to high temperatures. This article discusses the effects of high temperatures of 25, 200, 300, 400, 600 and 800°C and 3 hours of exposure on concrete samples replaced by red mud at 0, 10, 15 and 20%. To study the concrete’s mechanical and permeability properties, loss in weight, compressive strength, splitting tensile strength, capillary water absorption and water permeability tests were performed for all mixes. Results were closer to those of the control specimen, which ultimately supported the use of red mud at a ratio of 10%.

Services, systems and policies shape accessibility and affect the opportunities people have to participate in society. Aim: To gain an understanding of the accessibility policy of the built environment in Iceland through an exploration of policy documents. Method: Public policy documents regarding accessibility from official websites of local and national authorities in Iceland were collected and reviewed. Findings: This review summarizes policies and identifies critical concerns that need to be addressed to improve access to the built environment in Iceland: (1) inconclusive or incomplete information, (2) limited clarity in legislation and guidelines, (3) limited users’ involvement in policymaking, (4) insufficient monitoring of services and (5) limited fit with usability values. All those aspects are critical to ensure and protect disabled people’s rights to move around and participate in society.
All You Need is Cash: Corporate Cash Holdings and Investment after a Crisis

Cash is king as corporate revenues plummet during the COVID-19 lockdown. Evidence from the global financial crisis shows that firms with high pre-crisis cash holdings can invest during a crisis while their cash-poor rivals have to divest. This gives cash-rich firms a competitive advantage during the recovery period, resulting in a persistent and growing investment gap. The divergence in investment paths between cash-rich and cash-poor firms is particularly large for financially constrained firms and is absent during tranquil periods. Due to their ability to invest in a crisis, cash-rich firms can gain market share and accumulate more profits in the long-run. Cash balances at the onset of a downturn are therefore a key determinant as to whether firms emerge as winners or losers from a crisis.
ASSOCIATION BETWEEN NUTRITIONAL STATUS & COGNITIVE FUNCTON IN ELDERLY

Background: Malnutrition is one of the factors that affect cognitive function in elderly. Currently nutritional disorders are common in the elderly. It may be caused by a decrease in taste and smell function, socioeconomic factors, decreased mobility, accompanying diseases and decreased oral and dental health in elderly. Objectives: This study aimed to determine the association between nutritional status and cognitive function in the elderly. Methods: This cross-sectional study involved subject with consecutive sampling techniques. Elderly people aged over 60 years who were in the district of Medan Helvetia and fulfilled the inclusion and exclusion criteria were included in this study from February until April 2020. Cognitive examination were assessed using Montreal Cognitive Assessment Indonesian Version (MoCA-INA) and Visual Cognitive Assessment Test (VCAT). Nutritional status was assessed using Mini Nutritional Assessment (MNA). Results: This study was conducted on 71 samples consisting of 42 women and 29 men with a mean age of 68.68 ± 6.35 years. There were 32 subjects (45.1%) who were malnourished and at risk of malnutrition. The average MoCA INA score was 19.80 ± 4.07 and the VCAT score was 17.24 ± 5.17. Subjects who were malnourished (32 subjects) had lower MoCA-INA score and there was a relationship between nutritional status and MoCA INA with p = 0.002 (α <0.05). Subjects who were malnourished had lower VCAT score and there was a relationship between nutritional status and VCAT score with p = 0.004 (α <0.05). Conclusions: There is significant relationship between nutritional status and cognitive function in elderly.
Statistical Machine Translation between Myanmar (Burmese) and Kayah

— This paper contributes the first evaluation of the quality of Statistical Machine Translation (SMT) between Myanmar (Burmese) and Kayah (Kayah Li) languages. We also developed a Myanmar-Kayah parallel corpus (6,590 sentences) based on the Myanmar language of ASEAN MT corpus. The experiments were carried out using three different statistical machine translation approaches: Phrase-based Statistical Machine Translation (PBSMT), Hierarchical Phrase-based Statistical Machine Translation (HPBSMT), and the Operation Sequence Model (OSM). The results show that HPBSMT approach achieves the highest BLEU score for Myanmar to Kayah translation and Operation Sequence Model approach achieves the highest BLEU score for Kayah to Myanmar translation.
THE IMPACT OF CREDIT MANAGEMENT STRATEGIES ON LIQUIDITY AND PROFITABILITY

Extant literature showed the failure of many manufacturing organizations was due to poor profit maximization emanating from lack of adequate liquidity to initiate viable investments. The issue of low liquidity has been traced to weak credit management resulting in a poor receivable collection when due and bad debt losses. This study evaluated the impact of credit management strategies on the liquidity and profitabilityof quoted chemical & paints manufacturing companies in Nigeria. The descriptive survey research design was implemented. 500 staff representing 60% of the population was used as the sample population upon which copies of questionnaire were administered. 342 valid responses were returned by the participants and analyzed. One-way ANOVA was used for descriptive statistics, and a simple regression analysis method was used to test the formulated hypotheses. The result obtained indicated that the credit management strategiessub-variables credit risk assessment, debt recovery strategy, receivable collection policy, have positive and statistically significant impact on the liquidity sub-variable Ability to pay, level of bad debt, and cash inflow (R=.654 R=.632, p=.0<.05; R=.692, R=.674, p=.0< .05; R=.621, R=.601, p=.0<.05). The effect of liquidity on profitability was positive and statistically significant (R=.723, R=.701, p=.0<.05). The study recommended that organizations within the industry should improve liquidity to achieve the desired profit level by (i) having effective credit terms and proper risk assessment strategy, (ii) designed and implemented debt recovery plans to aid collection of the overdue debt, (iii) adopt a stringent credit collection method, and (iv) employ and retained qualified Accountants and Credit Administrators with excellent knowledge of credit control methodology.
