Optical Field Recovery in the Jones Space
Authors: Wu Qi 
Published: June 2022

<p> Optical full-field recovery makes it possible to compensate fiber impairments such as chromatic dispersion and polarization mode dispersion (PMD) in the digital signal processing. Coherent detection dominates over the long-haul transmission system due to its high spectral efficiency and tolerance against optical impairments. For cost-sensitive short-reach optical networks, some advanced single-polarization (SP) optical field recovery schemes are recently proposed to avoid chromatic dispersion-induced power fading effect, and improve the spectral efficiency for larger potential capacity. Polarization division multiplexing (PDM) can further double both the spectral efficiency and the system capacity of these SP carrier-assisted direct detection (DD) schemes. However, the so-called polarization fading phenomenon induced by random polarization rotation is a fundamental obstacle to exploit the polarization diversity for carrier-assisted DD systems. In this paper, we propose a receiver of Jones-space field recovery (JSFR) to realize polarization diversity with SP carrier-assisted DD schemes in the Jones space. There different receiver structures of proposed JSFR and the simplification for JSFR are explored theoretically. The proposed JSFR pushes the SP DD schemes towards PDM without no extra optical signal-to-noise ratio (OSNR) penalty. In addition, the JSFR shows good tolerance to PMD since the optical field recovery is conducted before polarization recovery. In the concept-of-proof experiment, we demonstrate 448-Gb/s reception over 80-km single-mode fiber using the proposed JSFR based on 2×2 couplers. Qualitatively, we compare the optical field recovery in the Jones space and Stokes space from the perspective of the modulation dimension. </p>

Published: June 2022

<p> Reconfigurable intelligent surface (RIS), nonorthogonal multiple access (NOMA), and underwater optical wireless communication (UOWC) are paradigms of technologies that drive the development of next generation communication systems. In this paper, we investigate the performance of a NOMA-based RIS-assisted hybrid radio frequency (RF) UOWC system. The ship works as a relay that redirects the received signal to two underwater destinations simultaneously. Due to the interruption of the direct link between the base station and the ship floating on the surface of the water, communication will be carried out via an RIS fixed to an intermediate building. In this paper, we provide new analytical expressions for the outage probability (OP), asymptotic analyses of the OP, and diversity order (D) to gain insights into the system performance. The results showed that the diversity order depends on the UOWC receiver detection technique. In the end, we illustrated that the NOMA-based RIS-assisted system significantly improves the outage performance of hybrid RF-UWOC systems over a benchmark system. <br>

Published: June 2022

Encouraging children towards the cognitive motivation through the discovery and knowledge of the environment around them is essential. Thus, during the two researchers’ supervision of the practical lessons that involved the female students’ application of their experience in the Applied Kindergarten Laboratory, it has been noticed that there was a difference in the cognitive motivation of kindergarten children. In order to reinforce the research problem, the two researchers sent an open questionnaire to a sample of randomly selected kindergarten teachers from Al-Karkh and Al-Rasafa sides. The responses collected accentuated the researchers’ sense of the existing problem. To achieve the aim of the study represented by examining the kindergarten child’s cognitive motive, and the differences of the motive in terms of gender variable (male, female), a sample of (150) (males, females) children of an age ranging between (5-6) years of the preliminary stage was selected. The sample was randomly selected from the governmental kindergartens in Baghdad from its two sides Karkh and Rusafa. The two researchers prepared a triple alternatives measure of cognitive motive, which consisted of (45) items divided into two fields. The first field that was concerned with knowing the environment that surrounds the child consisted of (26) items, whereas the second field, which is about problem solving, consisted of (19) items. The results have shown that kindergartens children have a cognitive motive. To achieve the validity of the test, the researchers relied on the logic and constructive validity indicators. Moreover, to estimate the reliability of the study, Cronbach Alpha was adopted. The study have concluded that there were no statistically significant differences between the male/female variable with respect to the cognitive motive.
The Chicago School in Urban Sociology: A Socio-Historical Approach on the Pragmatic Thought Influence as a Theoretical Frame of Reference in it-1892-2020
Authors: Mahir Abdulwahid Aziz  
Published: June 2022

The present theoretical study analyzes the legacy of the Chicago School of Urban Sociology and evaluates it in the light of the growth and development of Chicago City and the establishment of sociology in it. Sociology has become an academic discipline recognized in the United States of America in the late nineteenth century, particularly, after the establishment of the first department of sociology in the University of Chicago in 1892. That was during the period of the rapid industrialization and sustainable growth of the Chicago City. The Chicago School relied on Chicago City in particular, as one of the American cities that grew and expanded rapidly in the first two decades of the twentieth century. At the end of the nineteenth century, the city witnessed the arrival of large numbers of immigrants from Europe and South America. Accordingly, this study aims to examine the heritage of the Chicago School in depth, focusing on its origin, genesis, and development of the Chicago School of Urban Sociology. It also sheds light on its emergence and dominance over the American academic edifice in the first two decades of the twentieth century. The study further aims to investigate the role of the pragmatic thought in the growth and development of this school as a prominent scientific edifice among all American universities. The golden age of this school and the creativity of its pioneers of the scholars continued until the mid-forties. Thus, the study is to explain the causes of its decline after the mid-forties of the last century. Then, it evaluates the reality of this school after the forties until the first two decades of the current millennium. The study concluded that although much of the urban sociology tradition in the Chicago School and its deeply rooted sub-fields was and remains important, constituting a centre to this discipline, this does not mean that the styles and methods of studies conducted under the Chicago School umbrella should be applied to the urban life of today’s cities. This is due to their inadequacy with the reality of urban life in industrial cities today. That is in return is because of the radical transformations at all levels, including economic, social, political and cultural, as well as the modern communication technologies that have changed the face of the world through what is called today globalization.

Authors: Irmawati Irmawati , Usman Andi Nilawati , Ahmad Mardiana , Arsyad Nur Aliya 
Published: June 2022

Background: Folic acid deficiency in pregnancy will cause impaired maturation of erythrocyte nuclei, resulting in the appearance of red blood cells with abnormal shapes and sizes referred to as megaloblastic anemia, further impaired folic acid metabolism will cause impaired DNA replication and cell division processes, and this will affect the work of all cells of the body, including in iron metabolism.
Objectives: This study aims to determine the effect of husband support on pregnant women who consume phthalate supplements for increased hemoglobin levels.
Design: This research design is a systematic review to find and review articles from databases and theories that are descriptive.
Data Sources: Search for articles using the old version of the Mendeley application by entering the keyword "folic acid in pregnant women with inclusion criteria, namely the year of publication 2017-2021, English, full text and open access. There were 11 articles that were willing to be reviewed based on the inclusion criteria.
Review Methods: Systematic review method by filtering on the Mendeley website based on inclusion criteria, then collected and made a summary of the journal including the name of the researcher, year of publication of the journal, research title, method, and summary of results or findings. Summary of research journals are entered in table 1.
Results: From the search for articles, 4,463 articles were found. After filtering 9 eligible articles based on inclusion criteria, it was found that the level of folic acid consumption for pregnant women was still very low. Husband's support from the family can encourage pregnant women to be more enthusiastic in dealing with the changes that occur during pregnancy, including maintaining a healthy pregnancy through increased pregnancy visits and consumption of folic acid supplements. Pregnant women who receive attention and support from their husbands and families are more likely to accept and follow the advice given by health workers compared to pregnant women who receive less attention and support from their husbands and families.
Conclusion: Husband support in pregnant women who take Folamil supplements for the improvement of Haemoglobin is an important factor and has a very large influence on the health of pregnant women, so cooperation is needed between health workers and the family, especially the husband, in order to improve the health status of pregnant women.

Authors: Sushma Devi Ningombam , Hatibarua Preeti , Borah Sunil Kumar , Mazumdar Nirmal 
Published: June 2022

A pot experiment was conducted at Horticultural Research Station, Kahikuchi, Guwahati, to study the effect of different sizes of plants on vegetative growth and flower production of Phaius tankervilleae. Five different plants with varying sizes and numbers of pseudo bulb were adopted as treatments which were replicated 4 times. The flowers bloom from April and the experiment shows T3 produces the maximum number of spikes (2.38) per plant and earliest spike initiation (250.77) days while T5 produces the least number of spikes (0.5) plants and took longest days for spike initiation with (255.13) days. Meanwhile, T1 produce more new pseudo bulbs (4.0) and the least number was seen in T5 with (2.14). But T5 plants produced the biggest new pseudo bulbs (2.85cm diameter). Irrespective of the numbers of the pseudo bulb, plants with bigger pseudo bulb produced a bigger plant, long spike, more spike, bigger and more number of flowers which are a superior trait for a good quality cut flower. Beyond the production of flowers, this experiment further promotes the multiplication of pseudo bulbs, which are necessary for increasing the population of the plants for restoring and conserving the plant population without further exploitation.

Основою продовольчої безпеки нашої держави є збільшення тваринницької продукції. Одним з напрямків вирішення даної проблеми є – поліпшення умов утримання тварин, в тому числі мікроклімату тваринницьких приміщень. Забезпечення необхідного мікроклімату в тваринницьких приміщеннях – одне з найважливіших умов ефективного ведення тваринництва. щоб навіть тварини в повній мірі реалізували свій генетичний потенціал, їм необхідно створити відповідні умови утримання.
Сучасні технології утримання тварин висувають високі вимоги до мікроклімату в тваринницьких приміщеннях. Відхилення параметрів мікроклімату від встановлених оптимальних меж призводить до збитків, що заподіюються хворобами та падіжом тварин.
За математичної обробки одержаних даних отримали формулу регресії, яка адекватно описує умови обробки внутрішнього повітря озоно-повітряною сумішшю.
Дослідженнями встановлено, що результати розрахунків отриманих даних дозволили визначити оптимальні параметри обробки внутрішнього повітря приміщення озоно-повітряною сумішшю, а саме: концентрація озону в ОПС–0,5 мг/м3; час обробки – цілодобово; витрати ОПС–0,05 л/хв.
Both task-irrelevant and task-relevant information trigger reactive conflict adaptation in the item-specific proportion-congruent paradigm
Authors: Spinelli Giacomo , Morton J. Bruce , Lupker Stephen J. 
Published: June 2022

AbstractAdapting attention flexibly is a fundamental ability of the human control system. In the color-word Stroop task, for example, congruency effects are typically smaller for colors and words that appear mainly in incongruent stimuli (mostly-incongruent items) than for colors and words that appear mainly in congruent stimuli (mostly-congruent items). At least part of this item-specific proportion-congruent (ISPC) effect is due to a process of reactive conflict adaptation that affords higher selectivity (i.e., more efficient selection of task-relevant information) when a specific stimulus is presented that is frequently associated in the experiment with conflicting task-irrelevant information. What is unclear, however, is whether, normally, this stimulus-specific adaptation is triggered by the task-relevant component, the task-irrelevant component, or both components of the stimulus. In two experiments, using modified color-word (Experiment 1) and spatial (Experiment 2) Stroop tasks that allowed task-relevant and task-irrelevant triggering processes to be dissociated, we found that the two processes have approximately equivalent impacts. Because these results were obtained in experiments imposing no limitations on the processes potentially contributing to the ISPC effect, these results challenge claims that the ISPC effect involves conflict-adaptation processes only in special situations. The ISPC effect may involve conflict-adaptation processes in most situations, with both task-relevant and task-irrelevant information triggering such processes.
Formación de Lectores a partir de la Propuesta Literaria de María Teresa Andruetto
Authors: Moreno-Velasquez Leidy Tatiana 
Published: June 2022

Con el paso del tiempo, la concepción de la lectura ha cambiado y junto a ella sus procesos y estrategias. En la lengua castellana, la lectura y escritura son dos términos que no solo se pueden definir como pilares de la educación, sino, que, además, son nominados como habilidades humanas que permiten discernir y plasmar el conocimiento. El objetivo fue fortalecer las habilidades comunicativas en los estudiantes, a través de la propuesta literaria de María Teresa Andruetto, para incitar el interés por la lectura de diversos textos, lo cual contribuyó en la consolidación de un pensamiento crítico y en la formación de sujetos activos intelectualmente. La investigación se realizó bajo el paradigma humanista, de enfoque cualitativo, diseño de investigación-acción y tipo practico. La población a la cual se aplicó la propuesta fue a un grupo de 12 estudiantes, los cuales se mostraron durante cada una de las clases participativos e interesados por los libros trabajados. Se realizó una encuesta, para recolectar información relacionada a la cantidad de libros leídos durante el último año. La validación obtenida surgió al realizar el análisis de cada uno de los talleres diseñados para cada sesión y posteriormente se estableció una triangulación con los instrumentos utilizados para la recolección de datos. Finalmente, mediante la aplicación de estrategias de comprensión lectora en la literatura infantil, se logró fortalecer los niveles de comprensión, e incitar el interés por la lectura, logrando así sujetos activos, con más posibilidades en la consolidación de un pensamiento crítico.
