Notwithstanding the wealth of research on migration and subjective wellbeing, the issue of moonlighting and its welfare implication among migrants has no traces in the empirical literature. Using the rich individual-level panel data from the National Income Dynamic Survey (NIDS), this study established a number of interesting findings: (a) there is moonlighting among international migrants; (b) hours spent on the primary job and financial motive, amongst other socio-demographic factors are key predictors of moonlighting (c) international migrants are more likely to have more than one job, very often to meet contingencies, but mostly to help smoothen consumption over the life cycle; (d) individuals who spend more hours on their primary job are less likely to moonlight. Regarding wellbeing and happiness, it is evident that moonlighting and hours spent on primary jobs negatively influence self-reported wellbeing and happiness. Given the ravaging effects of COVID-19, a better understanding of the post-pandemic migration trajectory, job search strategies, economic activities among migrants, with a specific focus on moonlighting and its implication on wellbeing, is essential to national and international policy rethinking in order to achieve a triple win for the migrant, the host and origin countries.

This issue consists of a book review and five articles that promote the practice of original research and policy discussions and provides a comprehensive forum devoted exclusively to the analysis of contemporaneous trends, migration patterns, and some of the most important migration-related issues in Africa. The review was made by Daniel Tevera on a book entitled “Citizen and Pariah”, by Vanya Gastrow. The reviewer made a critical and scholarly evaluation of the entire book. According to Tevera, the author informs the reader about the violent crime affecting Somali shopkeepers, their ability to access informal and formal justice mechanisms, and efforts to regulate their economic activities. The reviewer further indicates that, from the different chapters of the book it becomes clear that the author uses the term “pariah” as a social and geographical metaphor. The reviewer concludes that this book is an important contribution that is divided into three parts, consisting of twenty-one essays that delicately address the marginalization and victimization of immigrant entrepreneurs. The book clearly indicates that foreign shopkeepers with business interests in urban spaces have been victims of xenophobic attacks in most parts of South Africa.The first article by D e r e k Yu is entitled “The Impact of International Migration on Skills Supply and Demand in South Africa”. Using a quantitative method of research that involved the use and analysis of data from Census 2001 and 2011 as well as Community Surveys 2007 and 2016. This is the first study in South Africa that compares natives and immigrants with emigrants. The study analyzed the most recent census and survey data of the top five emigration destination countries and examined the well-being of South African emigrants in the United Kingdom, New Zealand, the United States of America, Australia, and Canada. The results of this study enhance the understanding of the impact of international migration on skills supply and demand in South Africa, and identify the skills needs of the country. The study also provides stakeholders and policymakers with insights to better identify the priority critical skills needs of the country – critical skills that are lost, and skills that are in great demand but in short supply – so that these skills needs can be prioritized when issuing work and residence permits to immigrants. The second article by Emmanuel Quarshie, Imhotep Paul Alagidede, Albert Duodu, and Edwin Teye Sosi is entitled “Moonlighting Behavior among Migrants: Determinants and Implications for Well-Being in South Africa”. The study applied quantitative research methods to measure the key determinants of moonlighting, defined as a “situation where an individual maintains primary employment and engages in additional work for pay”. The study also examined the differences that

EXPECTED SHORTFALL DENGAN EKSPANSI CORNISH-FISHER UNTUK ANALISIS RISIKO INVESTASI SEBELUM DAN SESUDAH PANDEMI COVID-19 DILENGKAPI GUI R
Authors: Andespa Reyuli , Maruddani Di Asih I , Tarno Tarno
Published: August 2022

In financial analysis, risk measurement is critical. Stocks are a sort of financial asset investment that is in high demand by investors. Expected Shortfall is one of the strategies used to assess stock investing risk (ES). ES is a risk metric that considers losses in excess of the Value at Risk (VaR). Cornish-Fisher Expansion (ECF) is used to calculate ES with data that deviates from normality and takes into account skewness and kurtosis values. This study used data from the closing price of Sri Rejeki Isman Tbk (SRIL) shares before and during the Covid-19 Pandemic (14 January 2019 to 18 May 2021), with non-normally distributed returns. According to the calculations, the risk that investors will bear using the ES ECF value for the next day before the Covid-19 Pandemic is 1.1752 and after the Covid-19 Pandemic is 3.3177% at a 95% confidence level. The risk that investors will bear for the next day before the Covid-19 Pandemic is 5.8928%, and after the Covid-19 Pandemic is 10.3703%, based on a 99% confidence level. The findings of the study reveal that the higher the amount of trust, the higher the risk.
ANALISIS KLASIFIKASI MENGGUNAKAN METODE REGRESI LOGISTIK BINER DAN BOOTSTRAP AGGREGATING CLASSIFICATION AND REGRESSION TREES (BAGGING CART) (Studi Kasus: Nasabah Koperasi Simpan Pinjam Dan Pembiayaan Syariah (KSPPS))

Published: August 2022

The Save Loan and Sharia Financing Cooperatives (KSPPS) is a financial institution that offers deposits, loans, and financing to its members while adhering to Islamic sharia rules. Customers payment behaviour is influenced by their background differences, such as age, gender, occupation, and so on. The classification method is used to determine the characteristics of members who are currently in arears or are stuck in arears. Binary Logistic Regression and Bootstrap Aggregating Classification and Regression Trees were utilized as classification methods (BAGGING CART). A Logistic Regression with binary response variables is known as a Binary Logistic Regression. By resampling 50 times, the technique with the BAGGING process is used to improve the performance of the classification using CART. Customer data from one of the KSPPS in Central Java in 2021 was used in this investigation. Gender, age, marital status, employment, education level, time period, and income were the independent variables in this study, whereas payment status was the dependent variable (not stuck and stuck). The Binary Logistic Regression approach had an accuracy of 78.67 percent with an APER 21.33 percent, a Press's Q of 24.65, and a specificity of 98.30 percent, according to the classification accuracy statistics. The accuracy of the classification produced by CART with an accuracy value of 77.33 percent with an APER 22.67 percent, the value of Press's Q is 22,413, and specificity is 94.91 percent, then approached by BAGGING process the accuracy of the resulting classification by predicting data testing accuracy value of 78.67 percent with an APER 21.33 percent, press's Q value of 24.65, and specificity of 96.61 percent. Based on these findings, it can be inferred that using the BAGGING process can increase the CART method's performance to the point where it is nearly as good as Binary Logistic Regression, which has a slightly higher classification accuracy

Additive hazard regression is a survival analysis that is an alternative to Cox proportional hazard regression. The additive hazard models that have been developed include the Aalen additive hazard model and the Lin-Ying. In this study, Lin-Ying additive hazard regression was used as an analytical method to be applied in stroke data that had been hospitalized at Pandan Arang Hospital Boyolali. This method is considered more effective because there is no assumption of proportionality. The purpose of using this method in this study are analyze the characteristics of stroke patients, form a Lin-Ying additive hazard regression model, find out the factors that affect the rate of improvement of the clinical condition of stroke patients, and interpret the model. Based on the analysis that has been done, the average length of hospitalization is 4,471 days ≈ 4 days, and the factors that significantly affect the rate of improvement of clinical conditions in stroke patients at Pandan Arang Hospital Boyolali are blood pressure and blood sugar.

Published: August 2022

In 2017 to 2020 the Jakarta Islamic Index (JII) showed a positive trend and was quite stable compared to the LQ45 index. The selection of the JII stock index in this study is intended to obtain maximum profits. Investors are expected to create a series of portfolios to get maximum profit. One of the ways to identify stocks for portfolio formation is to use factor analysis. Factor analysis is used to summarize a large number of variables into new, smaller factors. This new factor is called the portfolio. The Mean Absolute Deviation (MAD) method is used for the formation of an optimal portfolio as well as an improvement on the Markowitz method in terms of non-linear (quadratic) mathematical models. The MAD method is the mean of the absolute value of the deviation between the realized return and the expected return. The optimization technique used in the MAD portfolio is the simplex method. Optimizing the objective function by constraining the set of constraints on the simplex method is done by forming a simplex table. Based on the processing using the simplex method, the investment weight for each of the stocks that make up the first portfolio is 30% CPIN shares; 29.23% of JPFA's shares; 10.77% shares of SMGR; and 30% shares in UNVR. Meanwhile, the investment weight of the constituent stocks for the second portfolio is 30% ACES shares; 10% of ERAA's shares; 30% of INCO's shares; 30% of PGAS shares; and 0% WIKA shares. The results of portfolio performance evaluation show that portfolio 2 is better than portfolio 1, by looking at the Sharpe Index for portfolio 2 of 0.0135629 and portfolio 1 of -0.0281177.

Authors: Ressa Theodoto
Published: August 2022

Autism spectrum disorder (ASD) learners have capabilities but frequently experience functional and academic difficulties. This article calls attention to the current debates about autism and the challenges of including ASD students in school systems. I assert that supporting the education of ASD students locally and globally is critical for their wellness and society. I focus on the qualities of learners with ASD to reveal that they have the capacities and abilities to learn and maintain that they can succeed in schools and communities with appropriate support. I illustrate selected best teaching practices and discuss ways educators can use them to develop functional and academic skills of ASD learners and dismantle autism myths. I conclude by calling on stakeholders to promote inclusion and teach life and educational skills to enable ASD learners to grow and develop into individuals capable of having meaningful lives in school and adulthood.

Practical application of European biological variation combined with Westgard Sigma Rules in internal quality control
Authors: Song Zhenzhen , Zhang Jiajia , Liu Bing , Wang Hao , Bi Lijun , Xu Qingxia
Published: August 2022

Objectives

Westgard Sigma Rules is a statistical tool available for quality control. Biological variation (BV) can be used to set analytical performance specifications (APS). The European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) regularly updates BV data. However, few studies have used robust BV data to determine quality goals and design a quality control strategy for tumor markers. The aim of this study was to derive APS for tumor markers from EFLM BV data and apply Westgard Sigma Rules to establish internal quality control (IQC) rules.

Methods

Precision was calculated from IQC data, and bias was obtained from the relative deviation of the External quality assurance scheme (EQAS) group mean values and laboratory-measured values. Total allowable error (TEa) was derived using EFLM BV data. After calculating sigma metrics, the IQC strategy for each tumor marker was determined according to Westgard Sigma Rules.

Results

Sigma metrics achieved for each analyte varied with the level of TEa. Most of these tumor markers except neuron-specific enolase reached 3σ or better based on TEamin. With TEades and TEaopt set as the quality goals, almost all analytes had sigma values below 3. Set TEamin as quality goal, each analyte matched IQC muti rules and numbers of control measurements according to sigma values.

Conclusions

Quality goals from the EFLM BV database and Westgard Sigma Rules can be used to develop IQC strategy for tumor markers.
Interior reconstruction in tomography via prior support constrained compressed sensing
Authors: Sonkar Munnu , Najiya K. Z. , Sastry C. S
Published: August 2022

Local reconstruction from localized projections attains importance in Computed Tomography (CT). Several researchers addressed the local recovery (or interior) problem in different frameworks. The recent sparsity based optimization techniques in Compressed Sensing (CS) are shown to be useful for CT reconstruction. The CS based methods provide hardware-friendly algorithms, while using lesser data compared to other methods. The interior reconstruction in CT, being ill-posed, in general admits several solutions. Consequently, a question arises pertaining to the presence of target (or interior-centric) pixels in the recovered solution.
In this paper, we address this problem by posing the local CT problem in the prior support constrained CS framework.
In particular, we provide certain analytical guarantees for the presence of intended pixels in the recovered solution,
while demonstrating the efficacy of our method empirically.
Ecolinguistics: History, today, and tomorrow
Authors: Penz Hermine , Fill Alwin
Published: August 2022

Since the concept of ecology was first applied to language over 50 years ago, the field of ecolinguistics has developed into a thriving branch of linguistics that is more than ever closer to the pressing issues of our time. This article aims to trace the historical development of ecolinguistics, discusses the main trends in current research, and provides a brief projection of potential future developments. The first part includes an overview of research connected to Einar Haugen’s article “Ecology of Language”, published in 1972, which focuses on the interaction between languages in multilingual contexts. A large part of the article is then devoted to the role of language in dealing with environmental problems (e.g. aggravating or solving them), which is the biological understanding of ecology in the study of language inspired by Halliday’s 1990 talk “New Ways of Meaning: The Challenge to Applied Linguistics”. Ecolinguistics will certainly have an interesting future. It will take up topics such as climate change, which surprisingly has largely been excluded from ecolinguistic research until recently. Other topics that need to be dealt with are the negative effects of tourism, the migration of human, plant, and animal populations. Ecolinguists, in the future, will also expand their methodology towards multimodal research and study how non-European languages present the ‘environment’, or rather ‘con-vironment’.
Like a shark in the ocean: the semiotics of extreme precarity in Joshua Tree rock climbing
Authors: Ness Sally Ann
Published: August 2022

During the mid-1970s the extraordinarily dangerous style of free solo climbing (climbing without protection) emerged in the collective practice of a small community of “Stonemaster” climbers actively developing new climbing routes and the new “free” style of roped climbing in what is now Joshua Tree National Park, California. While its emergence might be interpreted as an affectively-driven, macho embodied social semiotic or ethnomotricity, in actuality the evolution of free soloing in the case of Stonemaster-era climbing at Joshua Tree may be more accurately understood as the logical consequence of an intensive regime of practice in which climbers developed a near absolute bodily familiarity with certain climbing routes. Eventually, the reasonableness of climbing with little and even no protection on a subset of these routes became self-evident and conventional. Free soloing, in the semiotic perspective of the later Peirce, manifested as a Normal Logical Interpretant in the Joshua Tree landscape. It embodied the living definition of self-controlled conduct, and the Symbols it cultivated testified persuasively to the growth of a creative corporeal intelligence actualizing near absolute degrees of free will.

Published: August 2022

Es wird ein physikalisches und methodisches Konzept vorgeschlagen, das auf der Anwendung eines phononischen Kristalls zur Manipulation und Detektion heterogener Flüssigkeit in einem Kanal basiert. Der phononische Kristall wurde aus einem Edelstahlblock mit einer periodischen Struktur aus zylindrischen Löchern hergestellt. Ein Defekt der periodischen Struktur in Form eines flüssigkeitsgefüllten Kanals wurde in die Mitte des phononischen Kristalls gelegt. Die akustische Defekteigenmode wurde auf den Bandlückenfrequenzbereich des phononischen Kristalls abgestimmt. Eine wandernde akustische Welle wurde entlang des Defekthohlraums gestartet, um die heterogene Flüssigkeit zu manipulieren, und über den Hohlraum wurde eine lokale Schallsondierung der Zusammensetzung der Flüssigkeit mit Schallgeschwindigkeit durchgeführt. Als Beispiel für eine heterogene Flüssigkeit wurde Milch gewählt.
In-Situ Measurements of the Physiological Parameters in Lab-on-Chip Systems

Published: August 2022

Es ist von höchster wissenschaftlicher Relevanz, Biosensoren in Lab-on-Chip-Systeme zu integrieren. Die Integration der Sensoren in die Zellkultursysteme ermöglicht die direkte Messung der biologischen und physiologischen Parameter während des Zellwachstums. Es erfordert ein spezielles Design des mikrofluidischen Chips und eine Mikrostrukturierung der leitfähigen Materialien. In dieser Arbeit präsentieren wir zwei Ansätze für in-situ Messungen von physiologischen Parametern. Der erste ist eine Integration eines kommerziellen optischen Sensors für die Sauerstoffgehaltsdetektion und der zweite ist ein eigener, von uns entworfener und hergestellter transepithelialer Widerstandssensor (TEER) für Zellkonfluenzmessungen. Beide Sensoren wurden in einen flexiblen Mikrofluidik-Chip auf Basis von Polydimethylsiloxan (PDMS) integriert.
Ein Bottom-up Ansatz für die Radius- und Rundheitsmessung von Mikrokugeln
Authors: Oertel Erik , Manske Eberhard
Published: August 2022

Die mangelnde Verfügbarkeit von präzise charakterisierten Kugeln im Submillimeterbereich schränkt derzeit die Leistungsfähigkeit von Mikro- und Nano-Koordinatenmessgeräten ein. Aus diesem Grund werden am Institut für Prozessmess- und Sensortechnik der TU Ilmenau neue Ansätze zur Messung solcher Kugeln untersucht und daraus entsprechende Messverfahren entwickelt. Ein vielversprechender Ansatz basiert dabei auf einer Reihe von Oberflächenscans im Zusammenhang mit einem Stitching-Algorithmus. Als Oberflächensensor kommt zur Zeit ein Atomkraftmikroskop (AFM) im Kontaktmodus zum Einsatz. Eine rückführbare Messung erfordert eine präzise Charakterisierung der AFM-Spitzenform und deren Unsicherheit, um diesen Einfluss zu korrigieren und die Unsicherheit fortzupflanzen sowie möglichen Verschleiß der AFM-Spitze während des Messvorgangs festzustellen. Diese Aspekte fanden bisher keine Beachtung. Ausgehend von dem publizierten Stand wurde deshalb die Messstrategie und der Auswertealgorithmus durch eine geeignete Strategie zur Korrektur des Spitzenformeinflusses sowie der Ermittlung der Spitzenform erweitert. Diese wurde experimentell durch den Einsatz unterschiedlicher AFMSpitzen mit nominellen Radien von 100nm bis 2 μm an einer 300 μm-Rubin-Kugel untersucht. Im Rahmen des Beitrags werden dazu erste Ergebnisse vorgestellt und diskutiert.

For the chiral enantiomers 1 and 2, the circular dichroism (CD) spectrum was also investigated. X-ray structural analyses revealed that the structures of the cyanide-bridged Fe-Cu complexes 1 and 2 are characterized by two crystallographically independent but structurally very similar homochiral neutral chains, each consisting of the repeating units {[Cu(S,S-Chxn)2][Fe(bbp)(CN)3]} (1) or {[Cu(R,R-Chxn)2][Fe(bbp)(CN)3]} (2). The crystal structure of 3 likewise is build up of chains consisting of {[Cu(Cyclam)][Fe(bbp)(CN)3]} building blocks. The temperature-dependent magnetic susceptibility and field dependent magnetization of the complexes showed antiferromagnetic interactions in complex 1 between the Fe(III) and Cu(II) ions, while complex 3 is ferromagnetic, indicating that the magnetic coupling through cyanide linkage is very sensitive to the structure parameters around the paramagnetic metal ions. These results have been further confirmed by fitting of the experimental data using a uniform chain model, leading to the coupling constants J = −6.35 cm−1, g = 2.08, R = 4.42 × 10−4 and J = 1.24 cm−1, g = 2.09, R = ∑(χ

Inhibition or degradation of the anti-apoptotic protein BCL-XL is a viable strategy for cancer treatment. Despite the recent development of PROTACs for degradation of BCL-XL, the choice of E3 ligase has been restricted to VHL and CRBN. Herein, we report the development of MDM2-BCL-XL PROTACs using MDM2 as an E3 ligase for degradation of BCL-XL. Three MDM2-BCL-XL PROTACs derived from the MDM2 inhibitor Nutlin-3, which also upregulates p53, and the BCL-2/BCL-XL inhibitor ABT-263 with different linker lengths were designed, synthesized and evaluated in vitro. BMM4 exhibited potent, selective degradation activity against BCL-XL, and stabilized the tumor suppressor p53 in U87, A549 and MV-4-11 cancer cell lines. Moreover, the combination of BMM4 and the BCL-2 inhibitor ABT-199 showed synergistic antiproliferative activity. These unique bifunctional PROTACs offer an alternative strategy for targeted protein degradation.
Estimating methane emissions from underground natural gas pipelines using an atmospheric dispersion-based method

Methane (CH4) leakage from natural gas (NG) pipelines poses an environmental, safety, and economic threat to the public. While previous leak detection and quantification studies focus on the aboveground infrastructure, the analysis of underground NG pipeline leak scenarios is scarce. Furthermore, no data from controlled release experiments have been published on the accuracy of methods used to (1) quantify emissions from an area source and (2) use these emissions to quantify the size of a subsurface leak. This proof-of-concept work uses CH4 mole fraction, as measured by a single gas sensor, as an input to a simple dispersion-based model (WindTrax) under ideal conditions (i.e., in a field) and compares the calculated emissions to the known controlled NG release rates. The aboveground and surface CH4 mole fractions were measured for 5 days at a field testbed using controlled underground release rates ranging from 0.08 to 0.52 kg hr–1 (3.83–24.94 ft3 hr–1). Results confirmed that the mean normalized CH4 mole fraction increases as the atmosphere transitions from the Pasquill–Gifford (PG) stability class A (extremely unstable) to G (extremely stable). The estimated surface CH4 emissions showed large temporal variability, and for the emission rates tested, at least 6 h of data are needed to have a representative estimate from subsurface pipeline leaks (±27% of the controlled release rate on average). The probability that the emission estimate is within ±50% of the controlled release rate (P±50%) is approximately 50% when 1 h of data is collected; the probability approaches 100% with 3–4 h of data. Findings demonstrate the importance of providing enough data over time for accurate estimation of belowground leak scenarios. By adopting the estimation method described in this study, operators can better estimate leakage rates and identify and repair the largest leaks, thereby optimizing annual greenhouse gas emissions reductions and improving public safety.

The League of Women, until 1949 operating under the name Socio-Civic League of Women, was an organization created post-1945 in Gdańsk and Łódź districts. Its activity was dictated by the party and governmental authorities. During their early years, both the Gdańsk and the Łódź organizations were characterized by similar activities and range of influence on the local women’s milieus. After 1949, with the organization’s name changed to the League of Women, the Łódź branch enjoyed wider popularity and social acceptance among women. This was caused by the possibilities of building the organization’s influence among female workers in Łódź. The Gdańsk branch did not create rigid organizational structures due to, i.a., comparably less opportunities there for activity among employed women, especially workers. Also in Gdańsk, after 1980, the only reformatory movement among the League members in the country was born.
Jaka jest kobieta współczesna i jaką się stanie w przyszłości? Ciągłość i zmiana: opinie, diagnozy i antycypacje w prasie dla kobiet w Polsce międzywojennej

Published: August 2022

The interwar Polish press for female readers was creating visions of present and future woman. Journalists were showing social expectations, both traditional and modern. The former view was presenting woman as a good wife, mother, and a role-model for the future generations of Poles. Whereas the latter vision was showing female as an equal partner to a man in creating civilizational changes in the independent country. Press publications addressed to Polish women fulfilled an educative function, offering means and techniques of alleviating social tensions. Moreover, these articles were meant to create an image of a future woman, who is aware of her role in the society: private (household, social contacts) and public (work for common good).

Objetivo. Conocer la valoración de estudiantes acerca de la convivencia democrática en su escuela, la relación con sus compañeros y compañeras, la violencia en el plantel y el clima escolar en general. Metodología. Es un estudio de corte cuantitativo, transversal y correlacional, en el cual participaron 346 adolescentes entre 11 y 15 años de edad, de seis localidades del Estado de Sonora, México. Se utilizó la Escala de clima escolar y la Escala de convivencia escolar, ambas con evidencias de confiabilidad. Se realizaron análisis de comparación de medias a través del estadístico t de Student y de regresión logística. Resultados. Existe diferencia significativa entre los dos grupos contrastados: (a) quienes perciben violencia y han recibido molestias en la última semana en su escuela, y (b) quienes no perciben violencia y no han recibido molestias. El modelo de regresión logística arrojó una R de Nagelkerke de 0.58, que clasifica adecuadamente al 82,9% de los casos. Conclusiones. Este modelo de regresión logística es adecuado para predecir el riesgo del estudiantado adolescente de escuelas secundarias públicas de ser molestado por otros compañeros y compañeras, y percibir altos niveles de violencia. Por lo tanto, se recomienda realizar evaluaciones sistemáticas para identificar perfiles del estudiantado, además conocer las relaciones entre las dimensiones de convivencia y clima escolar.

Published: August 2022

Introducción. La masificación de la matrícula en las universidades hace que compitan por contar con más postulantes y se genera una diferenciación entre las carreras. Enfermería ejemplifica este proceso de expansión de educación terciaria en Chile. En este contexto, existe escasa evidencia de cómo se posesionan las carreras y qué diferencias en recursos del lenguaje utiliza el discurso publicitario. Objetivo. Análisis del discurso basado en la teoría de la valoración de las carreras de enfermería en sitios webs, e identificar los recursos valorativos de diferenciación en ellas. Metodología. Estudio descriptivo interpretativo. Se revisó un corpus de 41 sitios webs de enfermería con una descripción de los textos, identificación de recursos de valoración y determinación de los significados de las dimensiones de la valoración. Resultados. Las carreras de enfermería utilizan marketing en el que sobresalen las características del producto (de consumo) y la promesa de futuro por sobre aquellos discursos orientados a aspectos formativos-educacionales (como la calidad de la enseñanza o el énfasis humanista). Sin embargo, hay diferencias en los discursos al utilizar los recursos de valoración. En las universidades pertenecientes al Consejo de Rectores de Universidades Chilenas (CRUCH) se resalta el prestigio, mientras que en las universidades privadas (NO-CRUCH)) se utilizan todos los recursos para asegurar su distinción de marca en los sujetos postulantes. Recomendaciones. Las universidades, aunque difieren en las estrategias (prestigio/marca), apuntan a una misma práctica de captación del estudiantado. Se sugieren futuros estudios de la coherencia entre discurso de la oferta y la calidad de la formación educativa recibida, y control de la veracidad de los mensajes publicitarios en la educación.
