Wireless Sensor Networks (WSN) is a group of sensor devices, which are used to sense the surroundings. The network performance is still an issue in the WSN and an efficient protocol is introduced such as LEACH. To improve the stability, LEACH with fuzzy descriptors is used in preceding research. However the existing has drawback with effective group formation in heterogeneous WSN and also it is not achieved the Super Leader Node (SLH). To overcome the above mentioned issues, the proposed system enhances the approach which is used for increasing the energy consumption, packet delivery ratio, and bandwidth and network lifetime. The proposed paper contains three phases such as grouping formation, Leader Node (LN) selection, SLN selection with three main objectives:(i) to acquire Energy-Efficient Prediction Clustering Algorithm (EEPCA) in heterogeneous WSN for grouping formation (ii)To design Low Energy Adaptive Clustering Hierarchy- Expected Residual Energy (LEACH-ERE) protocol for LN selection.(iii)To optimize the SCH selection by Particle Swarm Optimization (PSO) based fuzzy approach. The clustering formation is done by Energy-Efficient Prediction Clustering Algorithm (EEPCA) in heterogeneous WSN. It is used to calculate the sensor nodes which have shortest distance between each node. The LEACH-ERE protocol was proposed to form a Leader Node (LN) and all the nodes has to communicate with sink through LN only. New SLN is elected based on distance from the sink and battery power of the node.

This paper represents an overview of 5S practices and its implementation in university laboratories to improve the quality of the laboratories. It also, highlights the contributions of 5S initiatives towards improving the maintenance of laboratory resources. It shows how learning, improvement, control and maintenance of the resources and activities are performed by reducing non-value added time, reduced cost and most importantly, laying the foundation for continuous improvement. Apart from these, implementation of 5S also increase the efficiency in terms of productivity by reducing the capital input. Furthermore, the involvement of faculty and laboratory staff in daily improvements is also critical for the success of implementation of 5S. It thus contributes to lean leadership which is a way of sustaining and continuously improving performance in the laboratory of the university. This paper shows how 5S is beneficial and why it is the foundation stone for any laboratory that wants to sustainably grow and become a benchmark.

Congestion management in restructured power system is a major technical challenge for the power system engineers. For a congestion free power market , Available transfer capability(ATC) is to be enhanced. ATC is a measure of remaining MW transaction that can be carried out without violating the transmission limits. In deregulated market , change in load can be met by more than one generator of the system generator participation factor is a measure of amount of power contributed by the generator to satisfy the load.This paper proposes that in simultaneous power transaction generator participation factor can decide the ATC of the network and can also change the maximum amount of load sustained by the bus before causing congestion of the network For this coding is done in MATLB and results are verified on Power world Simulator software.

Indian commodity traders are exposed to various risks like price risk, market risk, financial risk, credit risk, etc. To understand the risk resulting in the financial impact, this paper attempts to assess the historical trends of commodity prices and probability of loss occurrence in the commodity invested. The present study analyses five Indian agro commodities namely, Almond, Cardamom, Cotton, Guar Seed and Wheat using the data collected from secondary sources like Multi Commodity Exchange (MCX), Securities Exchange Board of India (SEBI) etc. This paper uses the Historical Simulation method for the calculation of Value at Risk (VaR) by considering spot prices of the commodities on MCX for a five year period (2013-2018). It is established that Value at Risk (VaR) is a relevant measure to arrive at risk which is useful for the commodity traders to estimate the financial risk and thus control the risk exposure.

This work analyzes experimental results of traffic control of unmanned vehicle convoy (UMV) with manned master vehicle in Russian road climatic environment. The problem of obstacle avoidance in driving lanes and position stabilization on preset motion path is reduced to the problem of dynamic stabilization of state variables. Its solution is aided by virtual data sensors requiring for minimum configuration of engineering tools. Relative positions of vehicles are determined by algorithms of combined data processing of navigation systems and machine vision which make it possible to solve this problem without visible road markings and radio vision for satellite navigation. Experimental results show that the developed control algorithms of UMV convoy are capable to solve the problem of its dynamic stabilization in actual traffic environment. The developed control algorithms of traction, braking, and path provide efficient operation on all types of surfaces including slippery roads. Scientific novelty of this work is comprised of experimental verification of efficiency of the developed solutions for advanced unmanned vehicles in Russia.

“Zhaomi” separable words generally use adposition to introduce the related arguments in pragmatic context. Under certain conditions, the adposition can be omitted or appear. Native Chinese speakers are not aware of the usage of this kind of separable words, while foreign students make frequent errors in their use. Based on the interlanguage corpus, this paper makes an all-round investigation and analysis of the errors of foreign students in learning this kind of separable words, and finds that there are some error types such as “single error” and “mixed error”. It also points out the causes of the errors from the two aspects of teachers and students.

It is natural that there are different aspects in language use due to cultural and environmental differences between Korea and China. Among the linguistic phenomena in which these differences appear, this study could often find that the expressions of Korean and Chinese appear differently in the comparison results of the comparative sentences in the Korean and Chinese modern novel texts. Among them, it was found that the expression of Korean corresponding to Chinese '大(Dae)' appears in various ways other than basic 'big'. Based on Langacker's model of network, the various expressions of Korean equivalent to the Chinese '大(Dae)', this study is going to first examine the meaning scope in the 'parallel relation' based on a theory, prototype, viewing ‘big’ in Korean as ‘大’ corresponding to Chinese 'Dae', and examine in depth how the various meanings of Korean are systematically related to Chinese 'Dae' through image and container schematics.

Kang Youwei, Liang Qichao and his colleagues of the reform group fled to Macau and established a Chinese newspaper, The Reformer China (Zhi Xin Bao) （1897.2-1901.2）. With the purpose of taking charge of political criticism by scholars, and exploiting people’s mind, The Reformer China formed a connecting link between the antecedent newspaper The Current (Shiwu Bao) and the succedent The China Discussion (Qing Yi Bao). In virtue of distinctive political ideas and positive ideological enlightenment, The Reformer China boasted significant historical value. The Reformer China contains a lot of arguments about the Korean Peninsula, and a considerable part of them are about the competition between Japan and Russia on the Korean Peninsula. By combing the coering of aggressive competition in Korea by Japan and Russia, a more comprehensive understanding the situation of Korean Peninsula at the turn of 19th to 20th century can be formed. Through the surface phenomenon of talking about Korea, both arguers and editors of The Reformer China conveyed the essence of the great political and national crises in modern China, and was alert to its future trend. This thesis illustrates the expatiation of Korea in The Reformer China, by analyzing its form and contents, especially referring to the covering of how Japan and Russia contended in Korea, thereby to judge its historical value and practical significant. It contains an introduction, three chapters in main body and the conclusion. The introduction presents the motivation of choosing this topic, analysis of the theoretical value and practical significant of carrying out this study, and summary of the domestic and foreign research status. Chapter 2 pays attention to the exposition of Russia’s yearning to possess Korea in 1897, concerning about the process of Russia’s embezzling Korea and the various privileges it seized. Chapter 3 analyses the reports of Japan and Russia invading Korea in 1898, and pays attention to the competition between Japan and Russia. Chapter 4 analyses the reports of Japan and Russia invading Korea in 1899-1900. In the conclusion, the historical value of the covering of how Japan and Russia contended in Korea in The Reformer China is judged.

Einerseits ist die Kategorie Raum geeignet, Macht zu gliedern, Hegemonien und Rückzugsorte zu ermöglichen und damit durch Differenzen kulturelle Bedeutung zu schaffen. Andererseits erschließt sich der Raum – sei es der landschaftliche, der urbane oder der Binnenraum des Privaten – von seiner Erlebbarkeit her dem Menschen erst, indem dieser in eine Relation zum ihm tritt. Die Geistes- und Sozialwissenschaften, die Naturwissenschaften bieten eine Fülle an „Räumen“, die noch abgeschritten, kartographiert und abgesteckt werden müssen. Die Autoren widmen sich jeweils in ihrem Fach, der Kartographierung des Wissens, den neu entdeckten, unbekannten oder einfach besonderen „Räumen“ – sowohl thematisch in den Vorträgen als auch hinsichtlich der Veranstaltungsorte.

Die Utopie im postutopischen Zeitalter
Authors: Ohme Andreas
Published: September 2019

Das Forschungsprojekt untersucht anhand theoretisch fundierter Einzelanalysen von gesellschaftspolitisch brisanten Texten der russischen Gegenwartsliteratur (Makanin, Pelevin, Tolstaja, Sorokin) die jüngsten Entwicklungen der utopischen Schreibweise. Dabei lautet die Ausgangshypothese, dass die literarische Gattung der Utopie, in deren Zentrum der Entwurf idealer bzw. abschreckender Gemeinwesen (Eutopie bzw. Dystopie) steht, auf die in verschiedenen soziologischen Zeitdiagnosen konstatierte zunehmende Delegitimierung des Staatsgedankens reagiert. Auf der Basis eines durch strukturelle und thematische Kriterien klar umgrenzten Korpus russischer Romane will das Forschungsprojekt deshalb die Fragen beantworten, welche Rolle die Idee staatlicher Ordnung in der zeitgenössischen Literatur noch spielt, welche Alternativen für die Organisation menschlicher Gemeinwesen gegebenenfalls imaginiert werden und welche Ausdrucksformen dabei in Anknüpfung an bzw. in Abgrenzung von den Gattungskonventionen der literarischen Utopie ausgebildet werden.
Nachwuchs als psychologische Ressource für die Bewältigung existenzieller Bedrohung
Authors: Hoppe Annedore
Published: September 2019

Das Bewusstsein der eigenen Sterblichkeit scheint dazu zu führen, dass Personen ihre Investitionen in Nachwuchs erhöhen. So stiegen die regionalen Geburtenzahlen nach einem Hurrikan in South Carolina und nach Bombenanschlägen in Oklahoma City an. In Laborstudien erhöhte das Bewusstsein der eigenen Sterblichkeit den Kinderwunsch, die Zahl gewünschter Kinder und die Intention, bald eigene Kinder zu bekommen. Zudem konnte gezeigt werden, dass typische defensive Reaktionen auf existentielle Bedrohung nicht mehr auftreten, wenn vorher über eigene zukünftige Kinder nachgedacht wurde. Kinder können demnach die Angst, die durch die Endlichkeit des eigenen Lebens ausgelöst wird, reduzieren. Aufbauend auf diesen Studien wird im Projekt untersucht, welche motivationalen Grundlagen dem erhöhten Kinderwunsch unter existentieller Bedrohung zugrunde liegen und warum Nachwuchs die Möglichkeit bietet, die Angst vor der eigenen Sterblichkeit zu reduzieren. Das Forschungsthema hat dabei auch gesellschaftliche Relevanz. Das Sinken der Geburtenzahlen in den meisten Industrieländern ist ein häufig diskutiertes Thema und Gegenstand vieler demografischer und soziologischer Untersuchungen. Der Einfluss existentieller Bedrohung auf die Geburtenzahlen bleibt bisher weitgehend unberücksichtigt.
STATISTICAL ANALYSIS OF THE MARIANA TRENCH GEOMORPHOLOGY USING R PROGRAMMING LANGUAGE
Authors: Lemenkova Polina
Published: September 2019

This paper introduces an application of R programming language for geostatistical data processing with a case study of the Mariana Trench, Pacific Ocean. The formation of the Mariana Trench, the deepest among all hadal oceanic depth trenches, is caused by complex and diverse geomorphic factors affecting its development. Mariana Trench crosses four tectonic plates: Mariana, Caroline, Pacific and Philippine. The impact of the geographic location and geological factors on its geomorphology has been studied by methods of statistical analysis and data visualization using R libraries. The methodology includes following steps. Firstly, vector thematic data were processed in QGIS: tectonics, bathymetry, geomorphology and geology. Secondly, 25 cross-section profiles were drawn across the trench. The length of each profile is 1000-km. The attribute information has been derived from each profile and stored in a table containing coordinates, depths and thematic information. Finally, this table was processed by methods of the statistical analysis on R. The programming codes and graphical results are presented. The results include geospatial comparative analysis and estimated effects of the data distribution by tectonic plates: slope angle, igneous volcanic areas and depths. The innovativeness of this paper consists in a cross-disciplinary approach combining GIS, statistical analysis and R programming.
The Rate of iPTF 14gqr like Ultra-stripped Supernovae and Binary Evolution Leading to Double Neutron Star Formation
Authors: Hijikawa Kotaro , Kinugawa Tomoya , Yoshida Takashi , Umeda Hideyuki
Published: September 2019

Double neutron star (DNS) systems are produced from massive binaries. A supernova (SN) explosion of an extremely stripped star is expected to occur at the final stage of DNS formation. This type of SN is called an ultra-stripped SN (USSN). Recent research revealed that a type Ic SN, iPTF 14gqr (SN 2014ft), has low ejecta mass (≈0.2 M
⊙) and its progenitor has a helium envelope with mass ∼0.01 M
⊙. This SN is interpreted as a USSN, and thus this is the first discovery of a USSN. Furthermore, the observation of iPTF 14gqr provides us with some information about its formation history. Here, we perform rapid population synthesis calculations so as to estimate the detection rate of iPTF 14gqr like USSNe with optical transient surveys: the intermediate Palomar Transient Factory (iPTF), the Zwicky Transient Facility (ZTF), and the Large Synoptic Survey Telescope (LSST). We find that iPTF, ZTF, and LSST can observe iPTF 14gqr like USSNe at rates of 0.3, 10, and 1 yr−1, respectively. The iPTF can detect 1 iPTF 14gqr like USSN during its four year observation. We also investigate effects of mass-loss efficiency during Roche-lobe overflow on formation channels.
Statistical Survey of Coronal Mass Ejections and Interplanetary Type II Bursts

Published: September 2019

Coronal mass ejections (CMEs) are responsible for most severe space weather events, such as solar energetic particle events and geomagnetic storms at Earth. Type II radio bursts are slow drifting emissions produced by beams of suprathermal electrons accelerated at CME-driven shock waves propagating through the corona and interplanetary medium. Here, we report a statistical study of 153 interplanetary type II radio bursts observed by the two STEREO spacecraft between 2008 March and 2014 August. The shock associated radio emission was compared with CME parameters included in the Heliospheric Cataloguing, Analysis and Techniques Service catalog. We found that faster CMEs are statistically more likely to be associated with the interplanetary type II radio bursts. We correlate frequency drifts of interplanetary type II bursts with white-light observations  to localize radio sources with respect to CMEs. Our results suggest that interplanetary type II bursts are more likely to have a source region situated closer to CME flanks than  CME leading edge regions.
Quantifying the Relationship between Moreton–Ramsey Waves and “EIT Waves” Using Observations of Four Homologous Wave Events
Authors: Long David M. , Jenkins Jack , Valori Gherardo
Published: September 2019

Freely propagating global waves in the solar atmosphere are commonly observed using extreme ultraviolet passbands (EUV or “EIT waves”), and less regularly in H-alpha (Moreton–Ramsey waves). Despite decades of research, joint observations of EUV and Moreton–Ramsey waves remain rare, complicating efforts to quantify the connection between these phenomena. We present observations of four homologous global waves originating from the same active region between 2014 March 28 and 30 and observed using both EUV and H-alpha data. Each global EUV wave was observed by the Solar Dynamics Observatory, with the associated Moreton–Ramsey waves identified using the Global Oscillations Network Group network. All of the global waves exhibit high initial velocity (e.g., 842–1388 km s−1 in the 193 Å passband) and strong deceleration (e.g., −1437 to −782 m s−2 in the 193 Å passband) in each of the EUV passbands studied, with the EUV wave kinematics exceeding those of the Moreton–Ramsey wave. The density compression ratio of each global wave was estimated using both differential emission measure and intensity variation techniques, with both indicating that the observed waves were weakly shocked with a fast magnetosonic Mach number slightly greater than one. This suggests that, according to current models, the global coronal waves were not strong enough to produce Moreton–Ramsey waves, indicating an alternative explanation for these observations. Instead, we conclude that the evolution of the global waves was restricted by the surrounding coronal magnetic field, in each case producing a downward-angled wavefront propagating toward the north solar pole, which perturbed the chromosphere and was observed as a Moreton–Ramsey wave.
Using the Extragalactic Gamma-Ray Background to Constrain the Hubble Constant and Matter Density of the Universe
Authors: Zeng Houdun , Yan Dahai
Published: September 2019

The attenuation produced by extragalactic background light (EBL) in γ-ray spectra of blazars has been used to constrain the Hubble constant (H
0) and matter density (Ωm) of the universe. We propose to estimate H
0 and Ωm using the well-measured >10 GeV extragalactic γ-ray background (EGB). This suggestion is based on the fact that the >10 GeV EGB is totally explained by the emissions from blazars, and an EBL-absorption cutoff occurs at ∼50 GeV in the EGB spectrum. We fit the >10 GeV EGB data with modeled EGB spectrum. This results in

and

. Note that the uncertainties may be underestimated due to the limit of our realization for EBL model. H
0 and Ωm are degenerate in our method. Independent determination of Ωm by other methods would improve the constraint on H
0.
Ab Initio Study of Ground-state CS Photodissociation via Highly Excited Electronic States

Published: September 2019

Photodissociation by ultraviolet radiation is the key destruction pathway for CS in photon-dominated regions, such as diffuse clouds. However, the large uncertainties of photodissociation cross sections and rates of CS, resulting from a lack of both laboratory experiments and theoretical calculations, limit the accuracy of calculated abundances of S-bearing molecules by modern astrochemical models. Here we show a detailed ab initio study of CS photodissociation. Accurate potential energy curves of CS electronic states were obtained by choosing an active space CAS(8,10) in MRCI+Q/aug-cc-pV(5+d)Z calculation with additional diffuse functions, with a focus on the B and C
1Σ+ states. Cross sections for both direct photodissociation and predissociation from the vibronic ground state were calculated by applying the coupled-channel method. We found that the C − X (0 − 0) transition has extremely strong absorption due to a large transition dipole moment in the Franck–Condon region, and the upper state is resonant with several triplet states via spin–orbit couplings, resulting in predissociation to the main atomic products C (3
P) and S (1
D). Our new calculations show that the photodissociation rate under the standard interstellar radiation field is 2.9 × 10−9 s−1, with a 57% contribution from C − X (0 − 0) transition. This value is larger than that adopted by the Leiden photodissociation and photoionization database by a factor of 3.0. Our accurate ab initio calculations will allow more secure determination of S-bearing molecules in astrochemical models.
Role of Planetary Obliquity in Regulating Atmospheric Escape: G-dwarf versus M-dwarf Earth-like Exoplanets
Authors: Dong Chuanfei , Huang Zhenguang , Lingam Manasvi
Published: September 2019

We present a three-species (H+, O+ and e−) multi-fluid magnetohydrodynamic model, endowed with the requisite upper-atmospheric chemistry, that is capable of accurately quantifying the magnitude of oxygen ion losses from “Earth-like” exoplanets in habitable zones, whose magnetic and rotational axes are roughly coincidental with one another. We apply this model to investigate the role of planetary obliquity in regulating atmospheric losses from a magnetic perspective. For Earth-like exoplanets orbiting solar-type stars, we demonstrate that the dependence of the total atmospheric ion loss rate on the planetary (magnetic) obliquity is relatively weak; the escape rates are found to vary between 2.19 × 1026 s−1 to 2.37 × 1026 s−1. In contrast, the obliquity can influence the atmospheric escape rate (∼1028 s−1) by more than a factor of 2 (or 200%) in the case of Earth-like exoplanets orbiting late-type M-dwarfs. Thus, our simulations indicate that planetary obliquity may play a weak-to-moderate role insofar as the retention of an atmosphere (necessary for surface habitability) is concerned.

It is commonly known that mathematics is used in many subjects in physics and chemistry courses and the relations between mathematics and variables are more easily understood. These courses also comprise a number of equations that correspond to a mathematical correlation and are also called formulas. Therefore, the aim of the present study is to determine the level of science teachers to verbally express the meaning of the equations given and comprehension of the mathematical structure of equations.The data obtained with the help of open-ended questions were analyzed by the content analysis method, one of the qualitative research methods. According to the data obtained, code, category and themes were created.The study was carried out with science teacher candidates studying at the Faculty of Education of Uludag University in the 2017 and 2018 academic year. When the obtained data were evaluated, it was found that majority of the teacher candidates had difficulty in expressing fully the concept of equation, and in perceiving the mathematical structure of the equations and in drawing the graphs of the equations.

Tabúes y pasiones. Ideas, afectos y prácticas en el cruce del Atlántico
Authors: Urroz Rosalina Estrada
Published: September 2019

Cruzar la frontera desde el mar adquiere otro significado, los puertos de partida y de llegada son, desde el afecto y la cultura, un paisaje a rememorar. Aquellos hombres y mujeres que llegan desde Francia a México, quizá a Veracruz, cargan con su pasado. En el cruce del océano construyen las palabras de la nostalgia, las cuales cobran vida en la correspondencia. Thiery de Menonville viaja a Oaxaca en el siglo XVIII con un claro propósito: apropiarse de la cochinilla para cultivarla en Santo Domingo; en la travesía observa la naturaleza y a los habitantes, admira el entorno, pero su corazón bate con prisa al observar a una bella mujer y al aproximarse a la posesión de su tesoro rojo grana. Desde la perspectiva de las sensibilidades, como diría Wickberg, transitamos de las representaciones hacia las formas de percepción y sentimiento. Situamos a Menonville en su tiempo como un ilustrado del siglo XVIII; de acuerdo con Mornet, estos hombres habrían conocido todas las formas del pensamiento contemporáneo. Libros e ideas también viajan y se instalan de peculiar manera, Parent du Châtelet es un ejemplo, sus planteamientos se encuentran inmersos en la disputa entre reglamentaristas y abolicionistas. Desde la ausencia, las subjetividades nos introducen en ese mundo habitado por múltiples espectros.
“Cafetín de Buenos Aires”, uma janela sobre a cidade moderna: solidão e melancolia na experiência do tango dos anos 1930 e 1940
Authors: Pereira Avelino Romero
Published: September 2019

Em sua análise da lírica de Baudelaire, Walter Benjamin aborda a cidade, a multidão, a melancolia e o choque traumático resultante do impacto da modernidade sobre a sensibilidade dos intelectuais e do público leitor oitocentistas. A experiência moderna e a circulação de ideias aproxima Paris e Buenos Aires, e os mesmos temas são recriados nessa nova manifestação lírica que é o tango-canción. Neste trabalho, analiso como alguns poetas do tango reagem à modernidade e elaboram uma identidade social em torno da melancolia e dos mecanismos e espaços de sociabilidade, em consideração aos representações sobre o “homem argentino” presentes nos escritos de Ortega y Gasset e Scalabrini Ortiz.
Navigating Academia Away From Home
Authors: Duru Adaobi Vivian , Akinro Ngozi
Published: September 2019

This study examined different adjustment challenges experienced by African-born faculty members in higher education in the United States. Using the critical race theory as a framework and in-depth interviews of a purposive sample of nine African-born academics selected from across the U.S., the authors explored the factors that militate against the smooth transition of these diaspora faculties in higher education in the country and offer insights into a better understanding of their needs and experiences. The findings show that African-born academics in U.S. higher education face challenges in communication, differences in academic systems, and culture, especially in the power distance between students and instructors. The authors offer recommendations for aspiring diaspora and African-born faculties and the policymakers in U.S. universities and colleges that hire these professionals.
The Nigerian Health Workforce in a Globalized Context
Authors: Archibong Uduak , Eshareturi Cyril
Published: September 2019

Nigerian health professionals are impacted by several global forces bearing down on them, one of which is the positive economic prospects associated with emigrating to work abroad. This emigration is an aspect of increased global mobility which has had an adverse effect on the Nigerian health economy. This is important globally because countries with the smallest healthcare workforce capacities such as Nigeria have the poorest health outcomes. The emigration of health professionals from Nigeria will continue until domestic structures such as improved healthcare infrastructures, job security, and financial rewards change for the better. Thus, it is important that measures aimed at supporting the Nigerian health workforce be implemented with a focus on building and managing for sustainability within the context of international interdependency. Accordingly, this chapter is aimed at creating a theoretical framework for building capacities and managing the challenges of the Nigerian health workforce vis-à-vis the opportunities offered by globalization.
Issues in Academic Leadership
Authors: Onyebadi Uche T. , Bland Dorothy , Howard Herman , Walcott Carolyn
Published: September 2019

Occupying administrative positions in any organization is an enormous and difficult task, especially in universities and other higher institutions of learning where the culture and conventional practices demand shared governance and collective decision making. Even more complex is when such positions are occupied by minorities who need to weigh a lot of factors in their decision making in order to effectively navigate and accomplish their duties and objectives. This chapter offers a brief theoretical insight into administrative leadership in the academy. More importantly, it provides the narratives of the personal experiences of administrators in the United States and Guyana; people whose gender and racial backgrounds categorize them as minorities. Sharing such experiences aligns with the purpose of this book and also provides some learning opportunities for people in the diaspora who aspire to become administrators in the academy and minorities who are currently doing the job.
Bio-Economy at the Crossroads of Sustainable Development
Authors: Vargas-Hernández José G.
Published: September 2019

This study aims to review, analyze, and systematize the knowledge created on bio-economy to develop a conceptual and theoretical framework based on the transdisciplinary study of biology and socioeconomy to be used in further research. It begins from the questioning of the benefits that bio-economy has compared to the neoclassical economy. The methods employed are critical analytic, descriptive, deductive-inductive, and it suggests holistic and transdisciplinary approaches. As a result, the core of the study presents the principles under which this new scientific paradigm in sustainable development can continue creating more scientific knowledge to be used in the formulation and implementation of strategic choices for the bio-production, bio-distribution, and bio-consumption processes.

Learning Communities
Authors: Robinson Heather , Kilgore Whitney , Bozkurt Aras
Published: September 2019

The purpose of this chapter is to present the similarities and differences of three learning communities: communities of practice (CoPs), professional learning communities (PLCs), and professional learning networks (PLNs). For this purpose, researchers adopted a qualitative phenomenological approach and interviews with three connected educators and content area experts were conducted regarding their views, perceptions, and experiences of the various learning communities and how technology (specifically Twitter) is used as part of their learning in an open community. Additionally, the interviews helped explain the current practices in community development and support, the evolution from a lurker to a contributor to a community leader, and the evolution from a community to a network.
