In the pixel zone: Perception of digital design
Authors: Tesařová Kateřina
Published: September 2022

Since the beginning of the millennium, the internet has undeniably influenced everyday life as well as the creative fields, in countless ways that have already been exhaustively discussed. In this paper, we discuss the term postdigital, which is relevant to anchoring the perception of digital design. Numerous theoretical works are dealing with the terminology of postdigital, with conceptualisations differing from one another. Post-digitality offers a set of speculative strategies with the intention of building a complex architecture for thinking and creating under contemporary conditions: how to critically consider, contextualize, and shift the perception of new technologies as part of the existing culture. Digital design has become an integral part of everyday reality: websites, mobile devices, tablets, but also products and services that use digital interfaces as interactive communication channels between a human and a machine. These interfaces require a specific approach to design. The term digital design covers the design of the entire range of digital products and services and is understood as a complex set of many disciplines: user interface, interaction design, information architecture, user experience design, visual design, web design, app design, or game design. The boundaries between the different areas of design are blurred and permeable, and although their mutual interaction can be beneficial, it is necessary to clearly differentiate between graphic and digital design. Digital design grows out of the principles of graphic (visual) design and introduces additional knowledge and very specific principles based on the nature of the digital medium and the transdisciplinary field of cognitive ergonomics.
Timely Estimates of the Monthly Mexican Economic Activity
Authors: Corona Francisco , González-Farías Graciela , López-Pérez Jesús
Published: September 2022

In this article, we present a new approach based on dynamic factor models (DFMs) to perform accurate nowcasts for the percentage annual variation of the Mexican Global Economic Activity Indicator (IGAE), the commonly used variable as an approximation of monthly GDP. The procedure exploits the contemporaneous relationship of the timely traditional macroeconomic time series and nontraditional variables as Google Trends with respect to the IGAE. We evaluate the performance of the approach in a pseudo real-time framework, which includes the pandemic of COVID-19, and conclude that the procedure obtains accurate estimates, for one and two-steps ahead, above all, given the use of Google Trends. Another contribution for economic nowcasting is that the approach allows to disentangle the key variables in the DFM by estimating the confidence interval for the factor loadings, hence allows to evaluate the statistical significance of the variables in the DFM. This approach is used in official statistics to obtain preliminary and accurate estimates for IGAE up to 40 days before the official data release.
Economic Nowcasting with Long Short-Term Memory Artificial Neural Networks (LSTM)
Authors: Hopp Daniel
Published: September 2022

Artificial neural networks (ANNs) have been the catalyst to numerous advances in a variety of fields and disciplines in recent years. Their impact on economics, however, has been comparatively muted. One type of ANN, the long short-term memory network (LSTM), is particularly well-suited to deal with economic time-series. Here, the architecture’s performance and characteristics are evaluated in comparison with the dynamic factor model (DFM), currently a popular choice in the field of economic nowcasting. LSTMs are found to produce superior results to DFMs in the nowcasting of three separate variables; global merchandise export values and volumes, and global services exports. Further advantages include their ability to handle large numbers of input features in a variety of time frequencies. A disadvantage is the stochastic nature of outputs, common to all ANNs. In order to facilitate continued applied research of the methodology by avoiding the need for any knowledge of deep-learning libraries, an accompanying Python (Hopp 2021a) library was developed using PyTorch. The library is also available in R, MATLAB, and Julia.

Published: September 2022

Internationalization is an inevitable phenomenon among all contemporary higher education institutions (HEIs) in a globalizing world. It is the driving force for development and progress. In course of the last 30 years, it became an inevitable element of HE management. However, it carries along a number of risks, pitfalls, and organizational challenges. To hedge those, quality assurance (QA) is called to the stage. HEIs therefore need not only to search for chances but also to increase the advancement of methods to safeguard the quality of education and research. It is for this reason that a discussion on the mutual evolution and impact of internationalization and QA is required, and this is the aim of this article to combine the issues dialectically. There are tools and institutions within the internationally and nationally developed QA concepts that have the potential and aim to secure the benefits of internationalization.

Published: September 2022

Bone loss is common in human old age and new materials that promote bone regeneration are an active line of research. In the present work, seven smart hydrogels based on PNIPAAm were synthesized with the prospective to be used in tissue engineering as a scaffold for bone growth. By changing the stoichiometric concentrations of the reagents and the synthesis parameters, hydrogels with different physical properties and morphology were obtained. Swelling, degradation properties, and crystallinity were analyzed. Physical properties were characterized using 1H-NMR, FTIR, and TGA. The results showed that the swelling degree (degree of mass expansion) varied at room temperature from 1,400% for less rigid hydrogels to 550% for stiffer hydrogels. With heating to body temperature, swelling decreases to 300% and 200%, respectively. The samples presented three-dimensional morphology, but they acquired different structures according to the magnetic stirring during the synthesis process. The crosslink and initiator concentrations have an important effect on the polymeric structure and thermal stability of the hydrogels. The PNIPAAm synthesized using 8.9 and 15.7 mol % of MBA are the most promising compounds to be used in the future as a scaffold for biomedical applications due to their high thermal stability, satisfactory 3D surface morphology, and shrinking-swelling property.

Published: September 2022

The aim of the study was to relate the influence of the chemical composition, structure, and basic properties as hardness of the tested drill bits on resistance to their wear. The chemical composition of the drill bit was investigated using the electric excitation emission spectrometry method and EDS microanalysis. Metallographic specimens were prepared and observed to determine the structure of each tool. Hardness tests were carried out on the shank and the working part of the tools. Material wear tests were carried out on the basis of measuring the wear of the drill bit flank. It has been shown that the appropriate selection of the chemical composition and heat treatment has a significant impact on the wear resistance of cutting tools, which directly translates into their quality.
The Impact of Access to Credit on Welfare Inequality in Malawi
Authors: Makuluni Fatso E. , Dunga Hannah Mayamiko
Published: September 2022

This study evaluates the implications that access to credit has on welfare inequality in Malawi in order to address the gap left in previous studies concerning credit. The study employed data from Malawi’s Integrated Household Survey 2017 and used the propensity score analysis to examine what impact access to credit may have on the welfare of Malawian households using consumption per capita as a proxy for household welfare. The study further proceeded to use the generalized Lorenz curve, the Theil indexes as well as the Gini to examine the inequalities present in welfare among the households that access credit and those that do not. The results showed a positive impact of access to credit on welfare as households with access to credit experience lower levels of inequality than those without. However, a closer examination of the Theil’s indexes found that factors unrelated to access to credit had a stronger effect on inter-household inequalities than access to credit. The results imply that the impact that access to credit has on welfare inequality is a positive one, but its effect is substantially small. Thus, implying that policies aimed at enhancing distribution of credit should continue. Simultaneously, a more holistic approach on reducing inequality should be included at both household level and national level to achieve a desired result.

OBJECTIVE: To determine the incidence of extrauterine growth restriction (RCEU) in very low birth weight (VLBW) newborn and associated factors. METHODS: Longitudinal, prospective study with very low birth weight premature newborns in a maternity school, carried out between October/2017 to September/2018. Demographic, clinical and nutritional variables were evaluated. The curves used at birth and to monitor growth were those of the INTERGROWTH Project. RCEU was defined as a Z score of birth weight < -2. In inferential statistical analysis, chi-square, Students t, Mann-Whitney and logistic regression tests were used. RESULTS: 97 children were analyzed, of which 41.2% developed RCEU. Weight, Z score at birth and caloric intake in the first week of life were higher in children without growth restriction. The use of mechanical ventilation, length of stay in intensive care unit, bronchopulmonary dysplasia and late sepsis were associated with RCEU in the bivariate analysis. In multivariate logistic regression, only the Z score of birth weight (p<0.001) and the use of mechanical ventilation (p=0.006) remained associated with the outcome. Regarding the nutritional status at birth, the higher the Z score of weight, the lower the incidence of RCEU. CONCLUSION: The incidence of RCEU found was high, with the nutritional status at birth and the use of mechanical ventilation as the main associated factors.

Published: September 2022

OBJECTIVE: The Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis after polio was eradicated from some countries. This review discusses clinical presentation, the most common causes and treatment effectiveness due to GBS medical importance. METHODS: This article is a review of literature developed among 15 articles found in the database MEDLIDE, Cochrane and LILACS, between 2010 to 2020. The criteria were language (English, Portuguese, and Spanish), literature review articles, systematic reviews and metanalysis and 18 years old patients or younger. RESULTS: The pathologic anatomy varies according to the clinical subtype of the syndrome, presenting a variety of clinical presentations. The diagnosis is based on clinical data, but exams can be needed due to case complexity and the variety of differential diagnoses. The treatment aims to accelerate patient recovery, decrease complications and avoid long-term neurological deficit. Intravenous immunoglobulin is the most effective treatment. Plasmapheresis is also beneficial when initiated early, also its a cheaper technique. Even in developed countries, 5% of patients with GBS die due to medical complications. CONCLUSION: The GBS is the first cause of acute flaccid paralysis, although there are therapeutic options, the death rate is significant, as well as the sequelae. Research about this syndrome is necessary, since the improvement on the knowledge and management would result in reduced morbidity and mortality.

Published: September 2022

OBJECTIVES: To perform a narrative review of the literature about current guidelines for food allergy and present the main recommendations for cows milk protein allergy (CMPA) management in children at primary health care by algorithms. METHODS: We searched for relevant publications on Cochrane Library, MEDLINE, PubMed, Guidelines International Network, National Guidelines Clearinghouse and National Institute for Health and Clinical Excellence (NICE) using the keywords on this topic. A comprehensive review of these publications as well as the recommendations of the Brazilian guide and consensus for food allergy was performed. CONCLUSION: Adequate diagnosis and treatment for CMPA in children is essential, considering its nutritional, emotional and socioeconomic burden. Clinical practice guidelines provide recommendations based on scientific evidence improving quality of care, however their implementation is challenging due to the lack of practical algorithms applicable and accessible for the management of CMPA in primary care. In addition, the lack of algorithms that favor accessibility to information from the extensive scientific content available is a reality that makes relevant the proposal for a management of CMPA more practical, applicable and acessible, in order to consolidate a clinical practice based on scientific evidence.

Published: September 2022

OBJECTIVE: To determine the frequency of dermatological diagnoses in preterm newborns and the associated perinatal factors. METHODS: This is a cross-sectional analytical study with a convenience sample and prospective data collection, carried out between November 2017 and May 2018. Were examined 151 premature and late preterm neonates admitted to the neonatal intensive care unit in a hospital of tertiary care level. The studied population was evaluated to evidence, describe and photograph the dermatological diagnoses present up to 28 days of life. RESULTS: The frequency of dermatological diagnoses was 99.3%, being the most observed: lanugo in 128 newborns (84.7%), salmon spot in 115 (76.1%), sebaceous hyperplasia in 89 (58. 9%), physiological flaking in 74 (49%), mongolian stain in 54 (35.7%), Epsteins pearl in 43 (28.4%), traumatic skin lesions in 42 (27.8%), milia cyst in 40 (26.4%), jaundice in 36 (23.8%) and toxic erythema in 20 (13.2%). Participants with a higher gestational age had a higher frequency of salmon spot, toxic erythema, mongolian spot, sebaceous hyperplasia, milia cyst and Epsteins pearl. CONCLUSION: Dermatological diagnoses were frequent and those of older gestational age had a higher frequency of physiological changes and birthmarks. Traumatic skin lesions were among the 10 most frequently observed, reinforcing the need to implement protocols for neonatal skin care, with emphasis on premature infants.
Non-celiac gluten sensitivity in pediatric patients: a literature review
Authors: Carvalho Vânia , Queiroz Nathalia
Published: September 2022

OBJECTIVE: This study aims to review the relevant bibliography about non-celiac gluten sensitivity in children and to summarize the main data of pathogenesis, symptomatology and diagnostic methods currently established, useful for clarifying the pediatric physician regarding this pathology. METHODS: The databases selected were: PubMed (The National Center for Biotechnology Information), LILACS (Latin American and Caribbean Health Sciences Literature) and SciELO (Scientific Electronic Library Online). Publications that contributed to the present review in the 2016-2021 interval, in English, Portuguese or Spanish, were chosen using the terms child, pediatrics, non-celiac gluten sensitivity and gluten sensitivity. RESULTS: Non-celiac gluten sensitivity occurs in patients in whom celiac disease and wheat allergy have been ruled out. Intestinal and extra-intestinal manifestations occur after eating gluten-containing foods and disappear after they are removed from the diet. The pathophysiological basis of non-celiac gluten sensitivity is related to the bodys innate immune response triggered by gluten peptides. The placebo-controlled double blind challenge test is considered the gold standard for diagnostic investigation, despite limitations. New methods are being tested in order to correctly affirm the diagnosis of non-celiac gluten sensitivity. CONCLUSION: The diagnostic determination of non-celiac gluten sensitivity is essential in order that the pediatric patient don’t be subjected, unnecessarily, to gluten-free diets that can have a negative impact on their nutrition and development.

Growth Acceleration and Demographic Structure: The Case of ECOWAS Countries
Authors: URSAVAŞ Uğur
Published: September 2022

The demographic structure of countries has significant effects on economic growth. Most developing countries are passing through a demographic transition. Although African countries still have higher fertility rates than other developing countries, fertility rates show a decreasing trend, which leads to a window of opportunity for potential demographic dividend for African countries. Within this context, this paper investigates the relationship between growth accelerations and demographic structure in ECOWAS (Economic Community of West African States) countries over the period 1961-2019. To do so, first, we identify the growth acceleration episodes using the growth acceleration methodology developed by Hausmann et al. (2005). Then, we test the demographic determinants of growth accelerations employing the panel probit regression method. The results show that while urban population and life expectancy have a significant and positive impact on the likelihood of growth accelerations, the fertility rate has a negative and significant impact on the probability of growth accelerations. In other words, an increase in urban population and life expectancy at birth increases the likelihood of growth accelerations, whereas an increase in fertility rate decreases the probability. However, the results show a negative but statistically insignificant relationship between age dependency, young-age dependency, and old-age dependency ratios and the likelihood of growth accelerations.

Published: September 2022

Küresel ısınma, çevresel kirlilik ve kaynakların kontrolsüz kullanımı insan yaşamı ve sürdürülebilir kalkınma için ciddi bir tehdit olarak kabul edilmektedir. Bu çalışmanın amacı BRICS–T ülkelerinde ekonomik büyüme, doğrudan yabancı yatırımlar ve çevresel kirlilik arasındaki ilişkileri çevresel Kuznets eğrisi ve kirlilik sığınağı hipotezleri bağlamında incelemektir. 1992–2017 dönemine ait yıllık verilerin kullanıldığı çalışmada ikinci nesil panel veri analizi yöntemleri uygulanmıştır. Eşbütünleşme testinden ulaşılan bulgularda değişkenlerin uzun dönemde birlikte hareket ettikleri yani eşbütünleşik oldukları tespit edilmiştir. Tahmin sonucunda BRICS–T ülkeleri için, çevre kirliliği ile ekonomik büyüme arasında ters–U şeklinde bir ilişkinin olduğunu ileri süren çevresel Kuznets eğrisi ve çevresel kirlilik ile doğrudan yabancı yatırımlar arasında pozitif bir ilişkinin olduğunu ifade eden kirlilik sığınağı hipotezlerinin geçerli olduğu belirlenmiştir. Nedensellik testinden ise ekonomik büyümeden çevresel kirliliğe ve çevresel kirlilikten doğrudan yabancı yatırımlara tek yönlü bir nedensellik ilişkisinin olduğuna yönelik ampirik kanıtlar elde edilmiştir. Elde edilen kanıtlar doğrultusunda BRICS–T ülkelerine, ekonomik büyümeden ziyade sürdürülebilir kalkınma ve çevre konularına daha fazla odaklanmaları ve doğrudan yabancı yatırım standartlarını geliştirmeleri önerilmektedir.

Authors: AKKAŞ Erhan , DOGAN-AKKAS Betul
Published: September 2022

The economic and political cooperation between the United Kingdom and Qatar has been at the agenda of the Gulf studies since the mid 19th century. Political consolidation in the state-formation process of Qatar, defence cooperation and economic ties based on energy and foreign investments are central elements of the parties’ relations for decades. In this respect, Qatar and Britain have been loyal allies, despite the changes in the regional political atmosphere and their domestic politics. The post-Brexit era might trigger the UK and Qatar to develop their economic and political bilateral ties. This paper aims to discuss what makes these countries mutually economically and politically attractive to maintain their dynamic partnership. The primary purpose of this research is the codification of the British-Qatari relations during the post-Brexit era while considering the continuities and the changes that bilateral ties have faced for years. This will assist in understanding the impact of Brexit, as well as the current blockade against Qatar, with a particular emphasis on the economic and political relationship between the two countries. In this context, this paper focuses on the ongoing defence cooperation and rising military trade between Qatar and the UK, in addition to trade and investment agreements after Brexit.

Published: September 2022

Bilgi ve iletişim teknolojilerinin gelişmesi, dijital dönüşümü gündeme getirirken işletmeler de yapı ve süreçlerini dijitalleştirmektedir. Bu doğrultuda işletmeler çeşitli stratejiler belirlemekte ancak stratejilerini uygulamaya geçirmek aşamasında sadece teknoloji desteği yeterli olmamaktadır. Bu noktada insan sermayesi faktörünün rolü önemli düzeyde hissedilmektedir. İşletmeler, yapılarını ve iş yapma yöntemlerini değiştirirken örgüt kültürü kavramını da bu yapı ve süreçlere uyumlu hale getirmektedir. Bunun bir adaptasyon ihtiyacı olduğu düşünüldüğünde organizasyonların yeni örgüt kültürünü benimsemeleri ve unsurları ile birleştirmeleri gerekmektedir. Dijital süreçleri yönetme sorunu tamamen farklı bir örgüt kültürünü ortaya çıkarmaktadır. İşletmeler için başarılı bir dijital dönüşümün gerçekleşebilmesi dijital dönüşüm kültürünün oluşturulabilmesi ile mümkün görünmektedir. Bu düşünceden hareketle araştırmada, işletmelerin dijital dönüşüm stratejileri ile performans ilişkisinde dijital dönüşüm kültürünün aracılık etkisini ortaya çıkarmak amaçlanmıştır. Bu amaç doğrultusunda Fortune 500 Türkiye sıralamasında yer alan 142 işletmenin; Bilgi Teknolojileri (BT) yöneticilerine veya Dijital Dönüşüm Direktörlerine (CDO-Chief Digital Officer) anket uygulanmıştır. Araştırmada işletmelerin, dijital dönüşüm kültürünü ve dijital dönüşüm performanslarını yüksek düzeyde değerlendirdikleri ile ilgili bulgular ortaya çıkmıştır. Araştırma sonuçlarına göre ise, işletmelerin dijital dönüşüm stratejileri ile dijital dönüşüm performansları arasında pozitif anlamlı ilişkiler ortaya çıkmıştır. Söz konusu ilişkilerde, dijital dönüşüm kültürünün belirleyici bir rol oynadığı sonucuna ulaşılmıştır.

Transition metal dissolution mechanisms and impacts on electronic conductivity in composite LiNi0.5Mn1.5O4 cathode films
Authors: Hestenes Julia , Sadowski Jerzy , May Richard , Marbella Lauren
Published: September 2022

The high-voltage LiNi0.5Mn1.5O4 (LNMO) spinel cathode material offers high energy density storage capabilities without the use of costly Co that is prevalent in other Li ion battery chemistries (e.g., LiNixMnyCozO2 (NMC)). Unfortunately, LNMO-containing batteries suffer from poor cycling performance due the intrinsically coupled processes of electrolyte oxidation and transition metal dissolution that occurs at high voltage. In this work, we use operando electron paramagnetic resonance (EPR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy to demonstrate that transition metal dissolution in LNMO is tightly coupled to HF formation (and thus, electrolyte oxidation reactions as detected with operando and in situ solution NMR), indicative of an acid-driven disproportionation reaction that occurs during delithiation (i.e., battery charging). X-ray photoelectron emission microscopy (XPEEM) provided surface sensitive and localized X-ray absorption spectroscopy (XAS) measurements that indicate that disproportionation is enabled by surface reconstruction that occurs upon charging that leads to surface Mn3+ sites on the LNMO particle surface that can disproportionate into Mn2+(dissolved) and Mn4+(s). During discharge of the battery, we observe high quantities of metal fluorides (particularly rich in MnF2) deposit in the CEI layer on the LNMO particles as well as the conductive carbon additives on the composite surface. Electronic conductivity measurements indicate that the MnF2 decreases film conductivity by 3-fold compared to LiF, suggesting that this CEI may impede both the ionic and electronic properties of the cathode. Our data indicate that in order to prevent transition metal dissolution and the associated side reactions in spinel-type cathodes (particularly those that operate at high voltage like LNMO), the use of electrolytes that offer improved anodic stability and prevent acid byproducts will be necessary.
Active Learning Assisted MCCI to Target Spin States
Authors: Seth Koushik , Ghosh Debashree
Published: September 2022

Strongly correlated systems and their accurate solutions have been challenging to quantum chemistry. Several methods have been developed over the years for the accurate understanding of such systems, and selected configuration interaction and Monte Carlo configuration interaction (MCCI) form important classes of systems in this category. However, MCCI is plagued by slow convergence. This is further exacerbated by the fact that most of the current MCCI implementations do not target specific spin states. In our work, we use active learning assisted MCCI to speed up the convergence manyfold and also develop a method for spin targeting. This method has been tested with several model Hamiltonian systems akin to molecular systems and has shown improved convergence and accuracy.

Authors: Clune Rachel , Cohen Orion , Das Avishek , Jasrasaria Dipti , Rossomme Elliot , Baranger Anne M.
Published: September 2022

We have designed and implemented a student-led mathematics bootcamp to improve mathematical skills and confidence among incoming physical chemistry doctoral students. The bootcamp is held immediately before the start of the first semester of graduate school and uses an active learning approach to review and practice undergraduate mathematics problems over five days in small student groups. We have developed content, which is now publicly available, for the bootcamp on select mathematics topics, including calculus, linear algebra, functions, differential equations, statistics and coding in Python, aiming at improving students' learning experiences in graduate quantum mechanics and statistical physics courses. Surveys before and after the bootcamp showed an increase in students' confidence in problem solving in key mathematical areas and in social aspects of peer-led group learning. Through qualitative and quantitative analysis, we demonstrate that the bootcamp reduced prior inequities in these metrics based on gender and mathematical background.
Coupling the Batch Adsorption Enrichment using Ternary LDHs with Struvite Crystallization in a Fluidized Bed Reactor for High-efficiency Phosphorus Recovery from Wastewater
Authors: Bah Amadu , Shen Ziyi , Yan Junna , Li Feihu
Published: September 2022

Adsorption represents a well-documented, effective and reliable means for phosphorus (P) recovery from waste streams, and is often followed by chemical precipitation for attaining value-added fertilizers or feedstocks. To assess the feasibility of recovering P from water by combining batch adsorption enrichment with struvite crystallization, we prepared four ternary layered double hydroxides (LDHs) with P-preferring elements (i.e., zirconium (Zr) or lanthanum (La)) via a facile coprecipitation method, and then evaluated their performance in capturing P from water, particularly in enriching P from a low-level P solution. We find that P adsorption on all ternary LDHs is pH-dependent and ionic strength-independent, showing a maximum adsorption efficiency at pH ~5 regardless of the ionic strength. Besides, all ternary LDHs demonstrate remarkably high P adsorption capacities, i.e., 842.2, 958.8, 499.6 and 1029.3 mg P g−1 under a certain condition for ZnFeZr, ZnFeLa, ZnAlZr and ZnAlLa, respectively, outperforming other LDHs reported so far. Microstructural analyses show that all ternary LDHs have high stability against the acidic or basic solution, and that the P uptake mechanisms are attributable to anion exchange between P and intercalated nitrate ions, complexation at both the edge of LDHs and the surface of metal (hydr)oxides co-occurred, and electrostatic attraction. Results of recycling tests indicate that all ternary LDHs present good enrichment for P, with enrichment factors above 2.6 after only five adsorption-desorption cycles. In addition, more than 96% of the phosphorus in the P-enriched eluates can be efficiently reclaimed via struvite crystallization in a fluidized bed reactor at an Mg:N:P ratio of 2:5:1 in the feed solution. These findings demonstrate the feasibility of combining adsorption enrichment with struvite crystallization for P recovery.

La mujer ha venido abriendo un espacio en la sociedad que le ha permitido visibilizar su capacidad productiva y de liderazgo; así mismo, en el mundo de la ingeniería y la educación, sin embargo, las investigaciones manifiestan que aún hay brechas significativas entre las condiciones laborales del hombre y la mujer que responden a temas culturales, de percepción, entre otros, y no necesariamente de habilidades o desempeños. De igual forma, hay áreas con vacíos conceptuales acerca de las condiciones de la mujer ingeniera que es educadora. Se pudo comprender que la presencia de la ingeniera en las instituciones educativas, ejerciendo la docencia, marcan de manera significativa a las estudiantes, pues se convierten en modelos a seguir y reeduca acerca del rol de esta en la sociedad, siendo parte de un proceso de formación integral de manera silenciosa que permite a las estudiantes sentirse identificadas y motivadas a verse en un futuro como profesionales con unas expectativas de vida diferentes. Lo anterior, relacionado, según el estudio, desde sus habilidades emocionales. Por lo tanto, se realizó el presente trabajo con mujeres que cumplen la condición de docente universitaria e ingeniera en 10 universidades colombianas, con la intención de relacionar el desarrollo profesional como docente y las habilidades emocionales de la mujer como elemento fundamental para su práctica docente exitosa, elemento que al mismo tiempo ha sido considerado como limitante y segregador. Se ha podido comprender que estas habilidades emocionales agregan un valor significativo en la manera de ejercer la docencia. Las mujeres encuestadas coinciden en considerar que hace parte del éxito profesional y la capacidad de articular en ellas los diferentes roles dados por la sociedad. Así mismo, aunque hay mejores oportunidades que permiten la capacitación de la mujer, aún hay mucho por hacer que permita promover e incrementar la equidad de género en el campo de la ciencia y la tecnología.

Las líneas de profundización dentro de un programa académico son estrategias propias de un currículo flexible que facilitan procesos de enseñanza-aprendizaje y su articulación con la investigación y la proyección social. Con estas, los programas académicos han logrado mejorar producción académica y científica, consolidar líneas de investigación y mejorar competencias básicas, generales y específicas. Es por esto, que su seguimiento y permanente actualización se convierte en una herramienta fundamental en procesos de evaluación curricular con fines de actualización de los planes de estudio. En su diseño curricular, el programa de Ingeniería Ambiental de la Universidad Santo Tomás articula 3 líneas de profundización que son: Tecnologías Limpias, Salud Ambiental y Recurso Hídrico. Sobre estas tres líneas, se ha desarrollado la investigación, la proyección social y la gestión curricular, de igual forma se han involucrado de manera transversal tanto en las áreas de ingeniería básica como aplicada. En la actualidad, el impacto de las líneas en las funciones sustantivas ha sido tan relevante, que se han convertido en el sello distintivo del programa. A partir de un análisis de las tendencias nacionales e internacionales, en el presente trabajo se muestra la pertinencia de las líneas de profundización. Dicho análisis se realiza en el marco del cumplimiento de los Objetivos de Desarrollo Sostenible como eje fundamental que direcciona las políticas de desarrollo de los países en la última década. Además, se hace una revisión del impacto de los egresados en el medio y se estudian las posibilidades de empleabilidad en estas áreas del saber. De la misma manera, se analiza la percepción de los sectores en que ha trabajado el Ingeniero Ambiental de la Universidad Santo Tomás y su desempeño. Finalmente se concluye que estas líneas propuestas han sido pertinentes para el desempeño de los Ingenieros Ambientales en el sector externo y de igual forma se proponen mejoras en cuanto al contenido curricular de las mismas con el fin de lograr un mayor impacto en la solución de las problemáticas ambientales de las comunidades a nivel global en el marco del modelo de desarrollo sostenible.
