Financial Conditions, Local Competition, and Local Market Leaders: The Case of Real Estate Developers

This paper studies whether (and how) corporate decisions are affected by internal factors (such as the financial conditions of own company) and external factors (such as the actions of local competitors) in an imperfectly competitive environment. We study the listed real estate developers in Beijing as a case study. Our hand-collected dataset includes transaction-level information booked indicators (such as profitability, liability, and liquidity) and un-booked financial indicators (political connections). Our multi-step empirical model shows that both the firm's financial conditions and her competitors' counterparts are essential but play different roles in the output design, pricing, and the time-on-the-market (TOM). Internal versus external factors' relative importance relates to the degrees of market concentration in a nonlinear manner. Local market leaders' existence alters the small firms' strategy and leads to higher selling prices and slower selling pace in the local market. Our findings survive various robust checks.
Investigation of glycolipids self-assemblies using fluorescence spectroscopy and small-angle X-ray scattering / Noor Idayu binti Mat Zahid

Glycolipids are one of the essential components of the cell membranes to carry out selected biological functions. Even though the study to resolve the ambiguity of biological membrane processes is continuously pursuit, it is now generally recognized that the lipids form lyotropic mesophases in the membranes. These phases are important biologically and technologically, thus our interest to characterize them. Herein, we investigate the microenvironment of various lipidic phases formed by mono- and dialkylated synthetic glycolipids using fluorescence technique. Both single and branched-chain synthetic glycolipids were observed to exhibit normal and inverse mesophases respectively. The polarity of different regions of the hydrophilic head group was estimated on the basis of a parallel study in different solvents using small fluorescent probes namely tryptophan (Trp) and two of its ester derivatives (Trp-C4 and Trp-C8). In contrast, the hydrophobic nature of pyrene is expected to favour the tail region of the self-assembly. The ratio of the two peak intensities (I1/I3) in the pyrene fluorescence spectra was used to elucidate the local environment of pyrene since it is environmentally sensitive. In addition, the lifetimes of all fluorescent probes in buffer and lipid were measured. We have also performed thermotropic and lyotropic investigations on four anomeric-epimeric related branched-chain glycolipids derived from Guerbet alcohols using small-angle X-ray scattering to obtain their detailed structural information as well as their partial binary phase diagram. Similar fluorescence study was carried out for one of these branched-chain glycolipids, which gave extensive inverse bicontinuous cubic phase. The results presented here are believed to be important for a better understanding of the glycolipids fundamental properties which may help uncover some biological mysteries.
Explorando la carrera dual en tenistas: diferencias según género y nivel competitivo (Exploring dual career in tennis players: gender and competitive level differences)

Los objetivos del presente estudio fueron: i) describir la carrera dual de tenistas de la Comunidad de Madrid; ii) analizar si existen diferencias en dicha carrera en funcion del genero, y iii) del nivel de competicion. Se elaboro un cuestionario ad-hoc teniendo como referencia el cues-tionario de percepcion de los estudiantes universitarios-deportistas de alto nivel sobre la carrera dual, ESTPORT (Sanchez-Pato et al., 2016). La muestra estuvo formada por 60 tenistas (21.5± 2.8 anos) residentes en la Comunidad de Madrid. De ellos, 55% eran hombres y un 45% eran mujeres. Entrenaban una media de 3.9 ± 1.3 dias y 17.2 ± 6.2 horas a la semana. Los resultados confirman que superan cada curso academico en dos anos aproximadamente, una falta de planificacion de su futuro fuera de la carrera deportiva y una elevada identificacion con el rol de deportista. Ellas tienen menos aspiraciones en su carrera tenistica, quizas por el hecho que el circuito profesional de tenis femenino sea mas modesto economicamente. En esa misma linea, al finalizar su carrera tenistica las mujeres piensan dedicarse a trabajar en lo que estudien en ma-yor medida que los hombres. Los jugadores de nivel internacional tienen un alto compromiso con su carrera deportiva. Sus mayores dificultades para su carrera dual no son en relacion a la falta de flexibilidad horaria para desarrollar ambas carreras. Se plantean recomendaciones practicas para los profesionales que trabajen con estos deportistas. === The aims of this study were: i) to describe the dual career in tennis players from the Madrid Region; ii) to analyze if there are differences regarding gender, and iii) competition level. An ad-hoc questionnaire was developed taking as reference the perception questionnaire of high-level university students-athletes about the dual career, ESTPORT (Sanchez-Pato et al., 2016). The sample was comprised by 60 tennis players (21.5 ± 2.8 years) residents in the Madrid Region. Fifty-five percent were men while forty-five percent were women. They trained an average of 3.9 ± 1.3 days and 17.2 ± 6.2 hours per week. Results confirm that each school year takes them about two years for passing it, a lack of planning a future out of the sport career and a high identification as athletes. Regarding gender comparison, women has less expectations on their sport career. This perception could be due the lower prize money in the women’s circuit. Women planned to work in relation to the studies the aim to finish. Regarding the competitive level, international level tennis players have a high commitment with the sport career. The main difficulties are not financial; they are the lack of flexibility at timetables to develop both careers. Practical insights for practitioners that work with tennis players are proposed.
Template-Free Formation of Monodisperse Doughnut-Shaped Silica Microparticles by Droplet-Based Microfluidics

Monodisperse doughnut-shaped silica microparticles are fabricated by a facile approach based on droplet microfluidics. As a result of rapid water diffusion, emulsion sol droplets shrink in the microfluidic channel. Inhomogeneous evaporation and buckling instability subsequently result in doughnut-shaped silica.
Microgrid protection against high impedance faults with robustness to harmonic intrusion and weather intermittency

The high impedance faults (HIF) in microgrids are characterized by low magnitude fault current with inherent non-linearity and random behavior. The possible weather intermittency in PV integrated microgrids and the intrusion of harmonics due to power converters and non-linear loading, further reduce the fault current during HIF. The insigniﬁcant fault current does not allow detection of HIF by conventional overcurrent relays. In this regard, a reliable and robust protection scheme based on the combined framework of probabilistic modelling, least square and Adaline algorithm, sine cosine algorithm (SCA) and support vector machine (SVM), has been proposed to perform the tasks of mode detection, fault detection/classiﬁcation and section identiﬁcation during HIF in microgrid. The algorithm involves online extraction of harmonic components and stochastic modelling of intermittency in solar irradiance. The performance of the proposed scheme has been analysed in terms of robustness against harmonics intrusion and weather intermittency during HIF. The performance comparison of the proposed scheme with the decision tree (DT) and classical SVM based techniques reﬂects its effectiveness with improved immunity against harmonic intrusion and weather intermittency. Further, the proposed scheme has been validated using OPAL-RT digital simulator for evaluating its appropriateness in real-time settings.
Differential response of Iris pseudacorus and Canna incida to water depth gradient

Field investigation was conducted to study the adaptability of Iris pseudacorus and Canna incida to water depth gradient(10,30,50,and 70 cm). It was observed that with the increasing water depth,the tiller numbers of I.pesudacorus and C.incida decreased significantly(P0.05),but the plant height,leaf length,and leaf width were less affected.Both the chlorophyll content and the root vigor of I.pseudacorus and C.incida decreased with increasing water depth,while the leaf MDA concentration was in adverse.The chlorophyll content,root vigor,and leaf MDA concentration of C.incida differed significantly among different water depths(P0.05),but only the root vigor of I.pseudacorus had significant difference(P0.05). Among the chlorophyll fluorescence parameters,the maximal light converting efficiency(Fv/Fm),apparent electron transfer rate(ETR),and photochemical quenching(qP)all decreased significantly with increasing water depth(P0.05),while the non-photochemical quenching(qN)had a significant increase(P0.05). The relative electron transfer rate(rETR),potential maximal rETR(rETRm),light use efficiency(α),and tolerance to intense light(Ik)all decreased obviously with increasing water depth.At water depth 10 cm,the values of all test indices were higher for C.incida than for I.pseudacorus;but at deeper water depths,an opposite trend was observed.It was found that deeper water depth had inhibitive effect on I.pseudacorus and C.incida,and the effect was greater on C.incida. Therefore,it should be kept in shallow water depth when using these two plants for wetland plant remediation in favor of the two plants' growth.The appropriate water depth for I.pseudacorus and C.incida would be 30-70 cm and 10 cm,respectively.
A Novel Method for Determination of Kinetic Friction Coefficient using Inclined Plane

Presented in this paper is the theoretical background for a novel method for determination of kinetic friction coefficient. The method is based on the equation of movement of a rigid body along an inclined plane and has not been previously discussed in literature. According to the theoretical results presented in this paper, mean kinetic friction coefficient can be determined based on the time it takes a rigid body to travel a distance along an inclined plane. Experimental results show that the mean kinetic friction coefficient increases with increasing mean sliding velocity, i.e. with decreasing sliding time. Increasing sliding velocity increases deviation of friction coefficients. This method also allows the determination of energy consumed due to friction along the travelled distance. Increasing mean kinetic friction coefficient and mean sliding velocity increases energy consumed due to friction. Practical calculation requires application of the distance law, which, in turn, requires accurate measurement of the sliding time and distance.
Mobile health monitoring based studies for diabetes mellitus: a review

Diabetes as a chronic disease is considered to be a serious problem not only for diabetic patients but also for caregivers, families and countries. Hazardously, as an example, 16% of the Middle East population died every year because of diabetes as it is reported by World Health Organization (WHO). Therefore, it is crucial to utilize the recent advances and technologies to find the best instrument for diabetes monitoring and management. Recently, mobile health (mHealth) technologies have a vital role in the healthcare industrial world. Undoubtedly, mHealth technologies are used to manage, track, monitor, diagnose, and prevent chronic diseases including, diabetes. Certainly, the main advantages of mHealth include a real-time and continuous monitoring with high reliability, accessibility, and availability. In addition to that, mHealth is considered to be a fast, accurate, simple, cheap, comfortable, and safe technology. Hence, the proposed study aims to review existing mHealth studies for managing, diagnosing, tracking, detecting, and predicting diabetic mellitus. Moreover, challenges and future trends of this emerging topic are also discussed.
Estimating Above-Ground Carbon Stock of Loa Haur Conservation Forest in East Kalimantan, Indonesia

Conservation forest in Indonesia holds the primary function as biodiversity preservation and maintains forest ecosystem, and therefore plays a significant role in reducing emission from deforestation and forest degradation (REDD) in East Kalimantan. To understand the forest’s role in holding emissions, information on current carbon standing stock is vital. This study aims to estimate above-ground carbon from East Kalimantan conservation forest, contributing up to 5.3% of the total forest area in this province. The study area is located at the Loa Haur education and training forest (Loa Haur forest) part of Bukit Soeharto Grand Forest Park. As many as 48 sample plots were established over 43.1 km of Loa Haur forests cover three main land cover types, i.e., secondary forest, shrub, and bare land. Above-ground biomass from sample plots was calculated using Chave allometric equations, while land cover types were derived from high-resolution Sentinel-2 satellite imagery. Carbon was estimated simply by multiplying biomass with a conversion factor of 0.47. Land cover of the study area was carefully classified using visual interpretation and was validated using actual land cover from the ground (sample plots). Accuracy assessment on land cover classification using Kappa value exhibited excellent results (Kappa index =0.83). This study also showed that the above-ground carbon stock of secondary forest, shrub, and bare land is 111.30 Mg/ha, 10.84 Mg/ha, and 4.63 Mg/ha, respectively. This above-ground carbon stock may refer to the emission factor, which can be used as a basis for calculating East Kalimantan carbon emission for a specific period.

Effects of Mineral Source on Growth and Balance in Yearling Horses1

Sixteen Quarter-Horse yearlings were used in a split-plot designed experiment to evaluate the response of growth and mineral balance to trace mineral source. Horses were blocked by sex and BW and randomly assigned to either an inorganic (ING) or organic (ORG) treatment. Diets were formulated to contain supplemental levels of Zn, Cu, Mn, and Co at four times NRC (1989) recommendations for yearlings in rapid growth. Diets were fed at 2% of estimated final BW and consisted of a pelleted concentrate, Marshall ryegrass hay, and alfalfa cubes fed in a 50:30:20 ratio, respectively. Three 72-h total fecal and urine collections were conducted on d 7, 30, and 60. Blood was taken on d 1 of each total collection to measure serum mineral (Zn and Cu) concentrations. Although mineral digestibility and balance data were not consistent across periods, significant increases in Cu (Period II) and Co (Periods II and III) digestibility and balance were observed for the ORG treatment. These increases indicate that ORG trace minerals may be more available for absorption as compared with IN sources, although excessive supplementation of trace minerals in the diet may obscure differences because of trace mineral source. Thus, the feeding of ORG trace minerals may improve trace mineral absorption, subsequently improving balance and digestibility.
Tropical cyclone characteristics associated with extreme precipitation in the northern Philippines

The Philippines is exposed to tropical cyclones (TCs) throughout the year due to its location in the western North Pacific. While these TCs provide much‐needed precipitation for the country's hydrological cycle, extreme precipitation from TCs may also cause damaging hazards such as floods and landslides. This study examines the relationship between TC extreme precipitation and TC characteristics, including movement speed, intensity and season, for westward‐moving TCs crossing Luzon, northern Philippines. We measure extreme precipitation by the weighted precipitation exceedance (WPE), calculated against a 95th percentile threshold, which considers both the magnitude and spatial extent of TC‐related extreme precipitation. WPE has a significant, moderate positive relationship with TC intensity with a non‐significant, weak negative relationship with movement speed. When TCs are classified by intensity 1 day before landfall (or pre‐landfall), Typhoons (1‐min maximum sustained wind speed ≥64 knots) tend to yield higher WPE than non‐Typhoons (<64 knots). On the other hand, when TCs are classified by pre‐landfall speed, slow TCs (movement speed <11.38 knots) tend to yield higher WPE than fast TCs (movement speed ≥11.38 knots). However, the relationship between pre‐landfall TC intensity and WPE is more pronounced during June–September while there is no significant difference between the WPE of the southwest monsoon (June–September) and northeast monsoon (October–December) seasons. These results suggest that it is important to consider the pre‐landfall cyclone movement speed, intensity and season to anticipate extreme precipitation of incoming TCs. A decision table considering these factors is devised to aid in TC extreme precipitation forecasting.

Sustainable Diets, A Way to Improve and Maintain Eating Behaviors and Health in Times of COVID-19 in First-Year University Students

Sustainable dietary pattern has reported multiple benefits for environmental and human health through sustainable food culture. The Covid-19 pandemic has led the population to adapt to a new virtual reality in all activities and to become more aware of their health. This study explores how evaluate the impact of nutritional education interventions on adherence to MD in first-year university adolescents, before and after the nutritional educational intervention. A total of 165 students participated in the experiment (85 intervention group and 80 control group). A 14-point questionnaire was applied for the adherence to the MD. The study consists of four presential sessions and four virtual sessions using social media to complete the training. The t-tests show that the group with interventions did not change its adherence during the two periods of data collection (p=0.187), contrary to the control group which significantly decreased (p=0.001) from 7.41 to 6.62. It has been concluded that it is necessary to work on institutional policies that promote the benefits of this dietary pattern as a lifestyle that would be beneficial to better cope with the pandemic, since many of the products of the MD are used in Latin-American countries for several years.
Nostalgia marketing: Examining music retromania

Nostalgia has a solid presence in marketing. Studies have shown that nostalgic marketing strategy could be a powerful tool to market some goods and services. It has been seen that nostalgic marketing campaigns are becoming a preferred way of making the most out of brand equity possessed by old products, logos, and packaging. This study examines the prospects of nostalgia marketing for the music market and probes the level of nostalgia among various sets of personal characteristics. The study has applied a two-stage stratified sampling method. Seven strata have been identified based on respondents’ occupation, then a random sampling technique for final sample selection has been applied. Results suggested that nostalgia proneness varies among different groups of people. The study also found a strong association between nostalgia proneness and some individual and group characteristics. The study is thus telling decision-makers to seriously look into the nostalgia fact so that opportunities could be exploited. As a future research direction, it is advised to conduct multiple rigorous studies to comprehend the issue from varied perspectives.
