Association Between Menstrual Patterns and Adverse Pregnancy Outcomes in Patients With Polycystic Ovary Syndrome

Objective To investigate the results of in vitro fertilization among polycystic ovary syndrome (PCOS) patients using the long-acting long protocol regarding the relationship between menstrual patterns and adverse pregnancy outcomes. Design Retrospective cohort study. Setting University-affiliated reproductive medical center. Background The menstrual patterns of patients with PCOS is considered related to metabolism; however, no study has analyzed the outcome of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) in patients with PCOS who have different menstrual patterns. This study aimed to observe the outcomes of IVF/ICSI in patients with PCOS with different menstrual patterns who used the long-acting long protocol. Methods This was a retrospective analysis in the first cycle of IVF/ICSI at the Reproductive Medicine Center of the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2019. In total, 1834 patients with PCOS were classified into the regular menstruation group (n=214), the oligomenorrhea group (n=1402), and the amenorrhea group (n=218). Results PCOS patients who used the long-acting long protocol of IVF/ICSI had similar clinical pregnancy rates and live birth rates despite having different menstrual patterns. The overall incidence of adverse pregnancy outcomes, including abortion, spontaneous preterm birth (sPTB), gestational diabetes(GDM), hypertensive disorder inpregnancy (HDP), and premature rupture of membranes(PROM, was significantly higher in the amenorrhea group than in the regular menstrual and oligomenorrhea groups (25.88% vs. 30.41% vs. 43.69%; P = 0.013). Additionally, the rates of GDM (2.35% vs. 6.10% vs. 13.79%; P=0.015) and macrosomia (5.26% vs. 10.94% vs. 18.39%; P=0.026) in the amenorrhea group were significantly higher than those in the other two groups. Correction for confounding factors showed that menstrual patterns are related to the occurrence of adverse pregnancy outcomes. Amenorrhea is an independent risk factor for adverse pregnancy outcome (OR [odds ratio]: 2.039, 95% CI [confidence interval]: 1.087-3.822), GDM (OR: 5.023, 95% CI: 1.083–23.289), and macrosomia (OR: 4.918, 95% CI: 1.516–15.954). Conclusions IVF/ICSI can achieve similar pregnancy and live birth rates in PCOS patients with different menstrual patterns. However, the overall incidence of adverse pregnancy outcomes in PCOS patients with amenorrhea is higher than that in patients with regular menstruation or oligomenorrhea.
Safety First: Perceived Risk of Street Harassment and Educational Choices of Women

This paper examines the long-term consequences of unsafe public spaces for women. It combines student-level survey data, a mapping of potential travel routes to all the colleges in the choice set, and crowdsourced mobile application safety data from Delhi. The findings show that women choose a college in the bottom half of the quality distribution over a college in the top quintile to feel safer while traveling, relative to men with comparable choice sets who choose a college in the top one-third of the distribution over a college in the top quintile. These findings have implications beyond women’s human capital attainment, such as their participation in the labor force.
Effects of vegetation covers for outdoor thermal improvement: A Case Study at Abubakar Tafawa Balewa University, Bauchi, Nigeria

Frequent increases in temperature and related consequences have been the trending phenomenon for over ten decades, with a general rise of about 0.740C. This study evaluates the effects of different percentage covers of tree canopies for outdoor thermal improvement of campus areas in Bauchi, Nigeria. Firstly, the study involves on-site measurement of existing features on the site and the climatic conditions. Secondly, performing simulation for evaluation of the plant-surface-atmosphere interactions with Envi-met Version 4.4. 2. The vegetation effects were evaluated for outdoor air temperature and mean radiant temperature (MRT) reduction. It is found that the maximum air temperature reduction of 3.380C and 24.240C of MRT were achieved with up to 45% tree canopy coverage. The mean air temperature and MRT reduction of 0.630C and 4.800C were respectively achieved with the same percentage coverage of the canopies. However, it was found that the thermal reduction effects of vegetation do not apply to every hour of the day. In essence, proper planning and implementation of campus outdoor spaces is the key factor in improving its thermal conditions. Thus, adhering to the practical recommendations bring a significant improvement in ameliorating the rise in atmospheric temperature on campus outdoors.
Simultaneous solid–liquid separation and primary purification of clavulanic acid from fermentation broth of Streptomyces clavuligerus using salting‐out extraction system

Clavulanic acid (CA) is usually used together with other β‐lactam antibiotics as combination drugs to inhibit bacterial β‐lactamases, which is mainly produced from the fermentation of microorganism such as Streptomyces clavuligerus. Recently, it is still a challenge for downstream processing of low concentration and unstable CA from fermentation broth with high solid content, high viscosity, and small cell size. In this study, an integrated process was developed for simultaneous solid–liquid separation and primary purification of CA from real fermentation broth of S. clavuligerus using salting‐out extraction system (SOES). First, different SOESs were investigated, and a suitable SOES composed of ethanol/phosphate was chosen and further optimized using the pretreated fermentation broth. Then, the optimal system composed of 20% ethanol/15% K2HPO4 and 10% KH2PO4 w/w was used to direct separation of CA from untreated fermentation broth. The result showed that the partition coefficient (K) and recovery yield (Y) of CA from untreated fermentation broth were 29.13 and 96.8%, respectively. Simultaneously, the removal rates of the cells and proteins were 99.8% and 63.3%, respectively. Compared with the traditional method of membrane filtration or liquid–liquid extraction system, this developed SOES showed the advantages of simple operation, shorter operation time, lower process cost and higher recovery yield of CA. These results demonstrated that the developed SOES could be used as an attractive alternative for the downstream processing of CA from real fermentation broth.
Analysis of Cash Flow Components, Gross Profit, Earnings per Share on Stock Returns Manufacturing Company Listed in the Indonesian Stock Exchange from 2016 Until 2018

The research objective was to determine the effect of cash flow components consisting of operating cash flow, investment cash flow, financing cash flow, gross profit, and earnings per share on stock returns. The population is the annual report of manufacturing companies listed on the Indonesia Stock Exchange for the period 2016-2018. Samples were taken of 32 company annual reports using purposive sampling method. Data collection using the documentation method. Data were analyzed using Multiple Linear Regression. The results of the operating cash flow analysis do not have a significant effect on stock returns. Investment cash flow has no significant effect on stock returns. Financial cash flow has no significant effect on stock returns and the results of gross profit analysis do not have a significant effect on stock returns. Meanwhile, earnings per share analysis has a significant effect on stock returns. Based on the results of the analysis, it can be concluded that the components of cash flow and gross profit are not reference variables for investors in making investment decisions and earnings per share are the main targets in making decisions. Therefore, companies must pay attention to earnings per share to attract investors. Keywords—cash flow components, gross profit, earning per share and stock return multiple linear regression
Smart Tourism Destinations from the Perspective of Travelers with Disability

This study elaborates a theoretical structure regarding the drivers of well-being and the conditions under which it is achieved by travelers with disabilities (TwDs) in a smart tourism destination (STD). The grounded theory was applied in the research. The focused coding revealed 65 codes distributed among 14 categories. The correlation among them established the theoretical code with the dimensions of the STD, their consequences, the drivers of well-being, and the moderating conditions of smart tourism experiences (STEs). The results showed that the STD generates trust, safety and autonomy in the TwDs, supporting the overcoming of physical and social barriers and favoring their well-being. The theoretical structure exposed relations that can be tested in future researches and focused codes that support the elaboration of items that can be used to measure the categories. The proposed model provides managers and policymakers with information to better welcome TwDs.

Organizational commitment does not mediate the effect of job characteristics on performance while organizational commitment mediates employee engagement on performance.
The influence of board independence on dividend policy in controlling agency problems in family firms

Purpose This study aims to investigate the impact of board independence on the cash dividend payments of family firms listed on the Borsa Istanbul (BIST) in balancing controlling families’ power to mitigate agency problems between family and minority shareholders in the post-2012 period. The authors focus on this period because Turkish authorities implemented mandatory regulations on the employment of independent directors on boards from fiscal year 2012. Design/methodology/approach The research model uses a panel dataset of 153 BIST-listed family firms over the period 2012–2017, employs alternative dependent variables and regression techniques and is applied to various sub-groups to improve robustness. Findings The empirical results show a strong positive effect of board independence on dividend decisions. The authors further detect that family directorship exhibits a negative effect, whereas both board size and audit committees have positive influences but chief executive officer (CEO)/duality has had no significant impact on the dividend policies of Turkish family firms since the new compulsory legal requirements in the Turkish market. Research limitations/implications The findings suggest that independent directorship and dividend policy are complementary governance mechanisms to reduce agency conflicts between families and minority shareholders in Turkey, which is a civil law-based emerging country characterized by high family ownership concentration. Practical implications The authors present evidence that Turkish family firms’ corporate boards have evolved, to some extent, from being managerial rubber stamps to more independent boards that raise opposing voices in family decision-making. However, independent directors’ preference for dividend-induced capital market monitoring implies that their direct monitoring is less effective than it is supposed to be. This suggests a need to revise the Turkish Corporate Governance Principles to enhance independent directors’ monitoring and supervisory power. Originality/value This is thought to be the first study to provide insights on how board independence influences dividend policy in controlling agency problems in Turkish family firms since Turkish authorities introduced compulsory rules on the employment of independent directors on boards.
Improving the Physical and Mechanical Performance of Laminated Wooden Structures by Low-Temperature Plasma Treatment

This paper considers the effect of RF plasma on wood in improving the adhesion of binders to wood by increasing its surface wettability. Our study reveals that radiofrequency (RF) plasma treatment causes a greater than threefold decrease in the marginal wetting angle of wood. The greatest effect is achieved in RF plasma treatment in argon, which is on average 5% greater than that of RF plasma treatment in air or in propane/nitrogen mixture. In addition, the power of the RF plasma torch has the greatest influence, and the main influence comes from the voltage applied to the RF plasma torch; current does not have such a significant effect. To achieve a significant effect, the duration of exposure should be at least 5 min, with a total power of 4.05 kW. Studies have been conducted to determine the adhesive strength of wood. An increase in the strength of laminated beams made from RF-treated bars in relation to control samples was found. The greatest impact on the adhesion strength was revealed when using PVA-based glue, compared with the use of polyurethane-based adhesives and urea-formaldehyde resin.
Succession Planning in Micro and Small Family Business (Case: Micro and Small Family Business in East Jakarta)

Family business studies are gaining a foothold in Indonesia. This organization is the most common type of firm throughout the world. Nonetheless, the low survival rate of family businesses may relate to the issue of management succession and the issue is still the principal challenge that they need to face. This study will focus on knowing the importance of succession planning for family business owners, especially those belonging to the micro and small business category. The study involved one hundred family business owners in East Jakarta as respondents of the survey. The study itself would be focused on the ground rules made by the incumbents during succession planning. The study has revealed that, generally, the majority of the sample does not have an appropriate plan of succession. The result also exhibits that the majority of respondents favoring nuclear family members as the future successor. Moreover, the homosocial reproduction phenomenon also could be identified from the survey.

Determinants of Consumption Behaviors of Korean Pop Culture in Taiwan

This paper presents a qualitative analysis of associations between intrinsic (e.g., functional), extrinsic (e.g., social) and cultural consumption values, and consumption behavior of Korean pop cultural contents (KPCC) in Taiwan. Moderation effects of Korean language abilities on associations are also investigated. Results show that intrinsic consumption value has the strongest association with KPCC consumption behaviors. Functional, epistemic, and conditional values have strong associations, whereas emotional and social exhibit weak associations. Cultural value is not a strong predictor of consuming KPCCs due to Korean and Taiwan cultural characteristics not being substantially different. Language abilities weakly moderate relationships between KPCC consumption values and consumption behaviors. Implications and suggestions are addressed. The research contributes findings and implications to the domain of KPCC marketing and retailing in Taiwan.
COMPARING THE VALUE RELEVANCE OF SELECTED ACCOUNTING INFORMATION IN CONSOLIDATED AND SEPARATE FINANCIAL STATEMENTS: THE CASE OF NIGERIAN LISTED FINANCIAL SERVICE FIRMS

In a company with a group structure, financial information is presented in two folds via consolidated and separate financial statements. The reporting of the similarly classified elements of financial statements arranged side by side in two columns carrying two different figures may be puzzling. Consequently, investors and other financial information users having two different figures available to them need to be guided as to which set(s) of information they need to make predictions and decisions. This study provides evidence about the comparative value relevance of accounting information for consolidated and separate financial statement of listed financial service firms in Nigeria. The study population is the entire listed financial services firms throughout the period of 2014-2018. Accounting information was represented by earnings per share, book value per share, dividend per share, and cash flow per share. These proxies were regressed against the market price per share. Data for accounting information were sourced from the annual reports of sampled firms and market prices from the Nigerian stock exchange factbook. A census sampling was used after a three-point filter was applied to the original population. The results show generally that both consolidated and separate accounting information is value relevant. However, consolidated accounting information is found to be more value relevant than separate accounting information. The study thus recommends the strengthening of firms’ operations, re-evaluation of the dividend policy, and enhanced implementation of IFRS standards to enhance value relevant accounting information that will be useful to the shareholders in making informed decision and taking adequate actions.
Antibiotic susceptibility profile of extended spectrum β-lactamase producing Escherichia coli, Klebsiella pneumoniae and Klebsiella oxytoca from Urinary tract infections

The aim of this study was to analyze the extended spectrum β-lactamases (ESBLs) production and antibiotic susceptibility profile of urinary tract infected bacterial pathogens such as Escherichia coli and Klebsiella spp. A total of 143 Gram-negative bacteria were isolated from people suffering from urinary tract infections (UTIs) were included in this study. Among them, Escherichia coli (75%) were the predominantly isolated bacterial pathogen followed by Klebsiella oxytoca (14.6%) and K. pneumoniae (10.4%). Approximately 65% (n=93) of isolates were positive for ESBL production and E.coli was found to be the highest ESBL producer (67.6%) followed by K. oxytoca (57.1%) and K. pneumoniae (53.3%). E. coli showed high level of 86.1% resistance to cefotaxime and cefuroxime and 100% sensitive to imipenem and meropenem, whereas, K. oxytoca showed high level of 90.5% resistance to cefuroxime and 100% sensitive to amikacin, imipenem and meropenem. Similarly, K. pneumoniae showed high level of 73.3% resistance to nitrofurantoin and 93.3% sensitive to imipenem. This study reveals that majority of UTIs caused bacteria are ESBL producing multidrug-resistant bacteria and showing broad spectrum antibiotic resistance profile.
Design of a Centralized Bioenergy Unit at Comarca Lagunera, Mexico: Modeling Strategy to Optimize Bioenergy Production and Reduce Methane Emissions

A centralized bioenergy unit was simulated, focusing on optimizing the manure transport chain, installing a centralized biogas plant, operation costs of the process, biogas upgrading, organic fertilizer production, and economic analyses. Comarca Lagunera from northeast Mexico was chosen as a study zone due to the existing number of dairy farms and livestock population (64,000 cattle heads). Two scenarios were analyzed: The first centralized scenario consisted of selecting one unique location for the anaerobic digesters for the 16 farms; the second decentralized scenario consisted of distributing the anaerobic digesters in three locations. Optimal locations were determined using mathematical modeling. The bioenergy unit was designed to process 1600 t/day of dairy manure. Results indicated that biomethane production was a more profitable option than generating electricity with non-purified methane. The amount of biomethane production was 58,756 m3/day. Economic analysis for centralized bioenergy unit scenario showed a net production cost of USD $0.80 per kg of biomethane with a profit margin of 14.4% within 10.7 years. The decentralized bioenergy unit scenario showed a net production cost of USD $0.80 per kg of biomethane with a profit of 12.9% within 11.4 years. This study demonstrated the techno-economical and environmental feasibility for centralized and decentralized bioenergy units.
Flattening of the Phillips Curve with State-Dependent Prices and Wages

We study monetary transmission in a model of state-dependent prices and wages based on ‘control costs’. Stickiness arises because precise choice is costly: decision-makers tolerate errors both in the timing of adjustments, and in the new level at which the price or wage is set. The model is calibrated to microdata on the size and frequency of price and wage changes. In our simulations, money shocks have less persistent real effects than in the Calvo framework; nonetheless, the model exhibits a substantial degree of non-neutrality, driven mainly by wage rigidity. State-dependent nominal stickiness implies a flatter Phillips curve as trend inflation declines, because price and wage adjustments become less frequent, making short-run inflation less reactive to shocks. Our model can explain almost half of the observed decline in the slope of the Phillips curve since 2000.
Purchase Intention of SUV Category Automobiles: Determinant Factors from the Customer Perspective

The study aimed to verify the impact of brand awareness, brand credibility, perceived quality, and perceived innovation as determinants of the intention to purchase SUV automobiles. For this purpose, quantitative research was carried out by applying a survey, with a convenience sample composed of 237 customers intending to purchase SUVs. Multivariate statistics were used to analyze the data through the Structural Equation Modeling approach. The study’s main contributions confirm that brand awareness positively impacts the SUV’s perceived quality, brand credibility, perceived innovation, and purchase intention. Brand credibility directly affects the SUV’s perceived quality. Perceived innovation also influences the SUV’s perceived quality. However, perceived innovation did not positively impact the purchase intention.
