A 2-year intercomparison of continuous-wave focusing wind lidar and tall mast wind measurements at Cabauw
Authors: Knoop Steven , Bosveld Fred C. , de Haij Marijn J. , Apituley Arnoud 
Published: March 2021

Abstract. A 2-year measurement campaign of the ZephIR 300 vertical profiling
continuous-wave (CW) focusing wind lidar has been carried out by the Royal
Netherlands Meteorological Institute (KNMI) at the Cabauw site. We focus on
the (height-dependent) data availability of the wind lidar under various
meteorological conditions and the data quality through a comparison with in
situ wind measurements at several levels in the 213 m tall
meteorological mast. We find an overall availability of quality-controlled
wind lidar data of 97 % to 98 %, where the missing part is
mainly due to precipitation events exceeding
1 mm h−1 or fog or
low clouds below 100 m. The mean bias in the horizontal wind speed is
within 0.1 m s−1 with a high correlation between the mast and wind
lidar measurements, although under some specific conditions (very high wind
speed, fog or low clouds) larger deviations are observed. The mean bias in the
wind direction is within 2∘, which is of the same order as the
combined uncertainty in the alignment of the wind lidars and the mast wind
vanes. The well-known 180∘ error in the wind direction output for this
type of instrument occurs about 9 % of the time. A correction scheme
based on data of an auxiliary wind vane at a height of 10 m is
applied, leading to a reduction of the 180∘ error below
2 %. This scheme can be applied in real-time applications in the situation that a
nearby freely exposed mast with wind direction measurements at a single
height is available.

Abstract. The Southern Ocean has a profound impact on the Earth's climate system. Its strong winds, intense currents, and fierce waves are critical components of the air–sea interface and contribute to absorbing, storing, and releasing heat, moisture, gases, and momentum. Owing to its remoteness and harsh environment, this region is significantly undersampled, hampering the validation of prediction models and large-scale observations from satellite sensors. Here, an unprecedented data set of simultaneous observations of winds, surface currents, and ocean waves is presented, to address the scarcity of in situ observations in the region – https://doi.org/10.26179/5ed0a30aaf764 (Alberello et al., 2020c) and https://doi.org/10.26179/5e9d038c396f2 (Derkani et al., 2020). Records were acquired underway during the Antarctic Circumnavigation Expedition (ACE), which went around the Southern Ocean from December 2016 to March 2017 (Austral summer). Observations were obtained with the wave and surface current monitoring system WaMoS-II, which scanned the ocean surface around the vessel using marine radars. Measurements were assessed for quality control and compared against available satellite observations. The data set is the most extensive and comprehensive collection of observations of surface processes for the Southern Ocean and is intended to underpin improvements of wave prediction models around Antarctica and research of air–sea interaction processes, including gas exchange and dynamics of sea spray aerosol particles. The data set has further potentials to support theoretical and numerical research on lower atmosphere, air–sea interface, and upper-ocean processes.
Effect of fear on two predator-one prey model in deterministic and fluctuating environment
Authors: Mukherjee Debasis 
Published: March 2021

Recent ecological studies on predator-prey interactions has concentrated on determining the impacts of antipredator behavior due to fear of predators. These studies are mainly confined into one predator-one prey system. But in case of multiple predator attack on single prey species, fear mechanism is still unknown. The combined impact of multiple predator often cannot be anticipated from their independent effects. So coexistence of multiple predators and prey’s fitness becomes an important issue from an ecological point of view. Based on the above observations, we proposed and analyzed a model consisting of two competing predator sharing a common prey where prey’s reproduction rate is affected due to fear generated by the predators. We first study the boundedness, uniform persistence, stability and Hopf bifurcation of the deterministic model. Thereafter, we have investigated the existence and uniqueness of the global positive solution, boundedness, asymptotic stability of the stochastic model. Numerical examples are provided to support our obtained results.

Utopic Dreaming on the Borderlands: An Anzaldúan Reading of Yuri Herrera's Signs Preceding the End of the World
Authors: Barrera Cordelia E. 
Published: March 2021

Abstract
The work of Gloria Anzaldúa has not typically been read in concert with utopian studies. Much of her writing, however, offers a rich resource for utopian critique. This is a significant omission given that much of Latin@ speculative fiction has been deemed inherently utopic. Latin@futurism is a field of inquiry by which to focus on the utopian as a broader category of visionary, speculative forms. Anzaldúa draws on techniques of defamiliarization to usher a change of consciousness in the reader, exemplified by her theories of conocimiento, el cenote, and nepantla. This article discusses Anzaldúa's theory of el cenote as a powerful heterotopic space of renewal and transformation in Yuri Herrera's novel Signs Preceding the End of the World. Anzaldúa's theories of conocimiento and nepantla flesh out culminating aspects of borderlands dreaming in the novel that connect to a discourse of apocalypse and its relationship to historical renewal and social justice.

Authors: Saldías Gabriel A. , Navarrete Carolina A. 
Published: March 2021

Abstract
This article aims to propose a critical and exploratory survey of utopian narratives published in Chile from 1829 to 1934 employing a qualitative and diachronic approach. The fundamental objective of this study is to make evident the thematic tendencies, formal recurrences, influences, and key differences in utopian works of fiction written over a century of Chilean history, connecting these with the overall development of Chilean society, in such a way as to express how the utopian narratives of this period reflect, critique, or rebel against the hegemonic social projects present in the country. Last, this article also seeks to approach these works from the distinctive point of view of the field of utopian studies, thus establishing the relevance of its theoretical framework in the analysis of Chilean fiction.
Study on Influence of a State of Dopants on Dislocation-Dopant Ions Interaction in Annealed Crystals
Authors: Kohzuki Yohichi 
Published: March 2021

Combination method of strain-rate cycling tests and application of ultrasonic oscillations was conducted for KCl:Sr2+ (0.035, 0.050, 0.065 mol.% in the melt) single crystals at low temperatures. The measurement of strain-rate sensitivity (λ) of flow stress under the application of ultrasonic oscillatory stress provides useful information on the interaction between a mobile dislocation and impurities (Sr2+ ions) during plastic deformation and the variation of λ with stress decrement (Δτ) due to oscillation has stair-like shape: The first plateau place ranges below the first bending point (τp1) at low stress decrement and the second one extends from the second bending point (τp2) at high stress decrement. The value of λ decreases with the Δτ between the two bending points. The τp1 is considered to represent the effective stress due to impurities when a dislocation begins to break-away from the impurities with the help of thermal activation during plastic deformation. Annealing the impure crystal by heat treatment, τp1 decreases obviously at low temperature and the critical temperature Tc, at which τp1 is zero, also becomes slightly smaller. Furthermore, it was investigated whether a change in the state of a small amount of impurities has an influential factor of the flow parameters (e.g., the activation energy, the density of forest dislocations) from the data analyzed in terms of Δτ vs. λ curve.
Quality Inclusion of Young Children with Disabilities: Taking a Stance to Support Early Childhood Leaders
Authors: Movahedazarhouligh Sara 
Published: March 2021

In the educational lexicon, inclusion is not a term, rather a philosophy that values and advocates for every child’s right to quality education and learning to develop their skills and realize their full potentials. Research over the past 40 years has demonstrated that inclusive education is associated with improved outcomes for children and students with disabilities. In early childhood (EC) education, inclusive education is in the best interest of all young children to improve their sense of belonging and membership, positive social relationships and friendships, and learning goals. As more EC programs, schools, and educational settings move toward including children with disabilities in general education settings, a need exists to better prepare EC professionals, most importantly EC leaders as gatekeepers of quality to better enhance and facilitate inclusive instructional opportunities for children with disabilities. This chapter focuses on EC leaders’ role in developing, adopting, and supporting inclusive education with recommendations to implement and sustain quality inclusive education practices in EC programs and settings.
Ocular Hypertension in Blacks
Authors: Laroche Daniel , Rickford Kara 
Published: March 2021

Ocular hypertension occurs when intraocular pressure (IOP) is greater than the normal range with no evidence of vision loss or damage to the optic nerve. Individuals with ocular hypertension have an increased risk for glaucoma. The mean normal IOP is 15 mmHg and the mean IOP of untreated glaucoma is 18 mmHg. Elevated IOP commonly occurs in patients over the age of 50 and is often due to enlargement of the lens, narrowing of the angle, iridolenticular apposition, and pigment liberation that obstructs the trabecular meshwork. Cataract surgery and lensectomy can lower IOP and reduce the risk of glaucoma. The global wealth inequality of Blacks has created health inequities that have led to decreased access to surgical care contributing to higher rates of blindness from glaucoma. Greater education on the benefits of early cataract surgery and trabecular bypass for higher risk patients, as well as addressing wealth and health inequities, can help to bend the curve of blindness from glaucoma.

Published: March 2021

Pt/SAPO-11 mesopores type materials has successfully synthesized using different templates, such as: diethylamine (DEA), dimethylamine (DMA), and n-propylamine (n-PA), under ultrasonication coupled with hydrothermal treatment or independently with hydrothermal treatment. The influences of structure directing agent (SDA) and synthesis method are investigated by different characterization techniques and the role of the material as catalyst in hydrotreating of sunflower oil has examined. The synthesized materials have been characterized by X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Fourier Transform Infra Red (FT-IR) techniques. It is found that SAPO-11 material which has synthesized with n-PA as a template has the characteristics of high silicon incorporation. Hydrotreating of sunflower oil is carried out in a fixed bed reactor with Pt impregnated SAPO-11 catalyst and a detailed study on the isomerization is performed by varying the operating parameters like temperature and space velocity. The high selectivity of Pt/SAPO-11 catalyst is achieved by uniform pore size and acidity. Also the pore opening of the catalyst has a major effect in the selectivity of the catalyst. Further, it represents a higher ratio of isomers compared to other synthesized catalysts on hydro-treating of sunflower oil. Copyright © 2021 by Authors, Published by BCREC Group.

Global importance of infertility and its treatment: role of fertility technologies
Authors: Hamberger L. , Janson P.O. 
Published: July 2002

AbstractUnderstanding the reasons for infertility and the development of new techniques for its treatment is one of the fields within medicine which has undergone a dramatic development during the last two decades. In the past, gynecologists seemed more successful in the treatment of female problems than urologists and andrologists on the male side, while in the last couple of years this scenario has changed due to the development of both operative procedures to harvest spermatozoa from the epididymis and the testis and the ability to micro‐inject single spermatozoa (ICSI) or even spermatides directly into metaphase II oocytes. It should, however, be emphasized that the successful development of in vitro fertilization (IVF) and other assisted reproduction technologies (ART), could not have taken place without the development of diagnostic innovations, such as immunoassays of hormones, high resolution ultrasound and various endoscopic techniques. Today, treatment of the infertile couple is less of a medico‐technical problem and more a socio‐economic dilemma. This communication is an attempt to summarize the more prominent steps in reproductive medicine during the last decades and one more general conclusion of global relevance which can be drawn, is that less money must be spent on diagnosis and more resources transferred to treatment options.
A definition of theory: research guidelines for different theory‐building research methods in operations management
Authors: Wacker John G 
Published: July 2002

AbstractThis study examines the definition of theory and the implications it has for the theory‐building research. By definition, theory must have four basic criteria: conceptual definitions, domain limitations, relationship‐building, and predictions. Theory‐building is important because it provides a framework for analysis, facilitates the efficient development of the field, and is needed for the applicability to practical real world problems. To be good theory, a theory must follow the virtues (criteria) for ‘good’ theory, including uniqueness, parsimony, conservation, generalizability, fecundity, internal consistency, empirical riskiness, and abstraction, which apply to all research methods. Theory‐building research seeks to find similarities across many different domains to increase its abstraction level and its importance. The procedure for good theory‐building research follows the definition of theory: it defines the variables, specifies the domain, builds internally consistent relationships, and makes specific predictions. If operations management theory is to become integrative, the procedure for good theory‐building research should have similar research procedures, regardless of the research methodology used. The empirical results from a study of operations management over the last 5 years (1991–1995) indicate imbalances in research methodologies for theory‐building. The analytical mathematical research methodology is by far the most popular methodology and appears to be over‐researched. On the other hand, the integrative research areas of analytical statistical and the establishment of causal relationships are under‐researched. This leads to the conclusion that theory‐building in operations management is not developing evenly across all methodologies. Last, this study offers specific guidelines for theory‐builders to increase the theory's level of abstraction and the theory's significance for operations managers.
