Published: April 2024

MOS capacitors fabricated on substrates with doping concentrations as high as 1018 cm−3 were characterized at 4.2 K. The highly doped substrate exhibited an intrinsic imaginary component of impedance at 4.2 K. The imaginary component is attributed to the time delay induced by hopping phenomena, leading to a decrease in the gate capacitance. Furthermore, we investigated the time constant associated with dopant ionization under depletion conditions and determined it to be 0.35 μs. An equivalent circuit model of the highly doped substrate at 4.2 K is also shown.

Branchless Banking and Financial Performance of Commercial Banks in Kenya
Authors: Njiru Francis , Ngaba Dominic
Published: April 2024

Commercial banks remain the principal constituents within the financial sector. Their performance is important since it serves other sectors, for example fishing, agriculture, manufacturing, energy and petroleum, mining, hospitality as well as tourism within the economy. Commercial banks’ performance shows a direct effect towards the overall economy and hence there is need for stability in their performance. The current study targets to evaluate how branchless banking impacts financial health of banks. The study aims to establish how banking via mobile phones affects Kenyan banks' performance, how ATM banking affects Kenyan banks' performance financially, how financial deepening affects Kenyan banks' performance financially due to branchless banking, and how regulations affect Kenyan banks' performance financially due to branchless banking. The study was in accordance with agency theory, financial deepening theory, and innovation diffusion theory. The study employed a correlation design and collected secondary data on commercial banks from 2012 to 2020. Causal research design was utilized, and all 39 commercial banks were included in the study. Regression analysis for data spanning eight years (2012-2020) was used. The study findings indicated that branchless banking has a significant impact on the financial performance of commercial banks in Kenya, with financial deepening playing a significant mediating role. Furthermore, bank regulations had a significant moderating effect on the relationship between branchless banking and commercial bank financial performance. The study recommends that commercial banks adopt branchless banking through mobile and ATM banking, increase customer usage of mobile banking, expand ATM banking services, and enhance financial deepening.
De Vlaamse Beweging en de patstelling van het Nederlands in de publieke overheid en het onderwijs in het jonge België (1830–1850)
Authors: Fabry Jan
Published: April 2024

Although the freedom of language use was anchored in the Belgian Constitution of 1831,in practice it led to almost complete Frenchification of public life, because civil servantscould choose their own language. Dutch thus became the language of the countryside andthe lower classes. Secondary and higher education were exclusively French speaking. TheFlemish Movement came into being as a reaction to this. Cultural associations werefounded and standards for Dutch language established. A petition in 1840 revealed theextent of the problem – the Flemish Movement demanded language equality and theestablishment of a Flemish Academy. Although there was partial success in 1850(Dutchification of primary and secondary education in Flanders), the petition alsoprovoked a hostile reaction among French speakers who accused the Flemings of antibelgitude. The Flemish Movement therefore issued a pro-Belgian manifesto. But thegovernment remained French speaking, so there was a stalemate.

Authors: Sroka Marek , Sówka Karola , Purzyńska Hanna , Puszczało Tomasz , Zieliński Adam
Published: April 2024

P92 (X10CrWMoVNb9-2) is commonly used for high-pressure elements of modern power units for supercritical steam parameters. As a result, steel is characterized by good strength, corrosion and creep resistance properties at elevated temperatures.

Welded joints of pressure elements of steam boilers are potentially the weakest points in assessing their service life. Therefore, they are a place where, during long-term operation, the continuity of the material within the weld, usually in the heat-affected zone, may be lost. Therefore, material studies of welded joints on the base material contribute to the understanding of degradation processes.

The paper presents microstructure and hardness testing of P92 welded joint after 5000h of annealing at 600 and 650°C. The hardness of the material was compared to the microstructure images in the initial state and after annealing. A scanning electron microscope carried out the microstructure tests.

CORROSION EVALUATION OF LPBF-MANUFACTURED DUPLEX STAINLESS STEEL
Authors: Brytan Zbigniew , Dagnaw Mengistu
Published: April 2024

In this study, the effect of as built and heat-treated additively manufactured 2507 super duplex stainless steel (SDSS) on electrochemical corrosion performance was examined. The corrosion was studied by Tafel polarization and electrochemical impedance spectroscopy (EIS) methods in a 3.5% NaCl solution. For this purpose, the as-built and heat-treated printed samples (solution annealed and stress-relieved) were examined by LOM/SEM and X-ray diffraction to evaluate the phase changes of steel at different processing stages. The correlation between corrosion resistance, structure, and heat treatment was assessed. As a result of the very fast cooling rate of the LPBF process, SDSS reveals ferrite as the major phase in the printed samples. To enhance the corrosion resistance of LPBF-produced duplex stainless steel, it's crucial to balance its two-phase structure and minimize residual stresses. The ferrite grains are elongated in the build direction, with some austenite precipitation along the grain boundaries or as Widmanstatten laths.  The stress-relieved and as-printed SDSS exhibits reduced corrosion characteristics by around 20% compared to the solution-annealed SDSS, according to anodic polarization curves. Based on EIS results, the solution-annealed SDSS revealed an almost double increase in corrosion resistance (based on charge transfer resistance values) compared to the as-printed and stress-relieved conditions.

A Seat at Whose Table? Analyzing Detroit’s Community Benefit Ordinance as a Tool for Environmental Justice
Authors: Gargaro Sarah
Published: April 2024

The Environmental Protection Agency defines environmental justice as the “just treatment and meaningful involvement” of all people in the decisionmaking that affects the environment and human health. Since the origins of the modern American environmental justice movement in the 1980s, activists have emphasized the importance of self-determination. Environmental justice requires that decision making processes center the voices of the individuals impacted by decisions made about the distributions of environmental assets and harms. There is a significant challenge, however, in designing community engagement practices that meaningfully involve community members. Since the 1990s, community benefits agreements have been heralded as an effective tool of community and grassroots control over development projects. In 2016, Detroit became the first city in the country to adopt an ordinance mandating the use of community benefits agreements in qualifying developments.

This Note endeavors to analyze Detroit’s community benefits ordinance as a tool for achieving environmental justice by examining where the ordinance succeeds in empowering community control over environmental decision making and falls short of this potential. Examining Detroit’s community benefits ordinance in the context of the larger environmental justice movement provides a rich opportunity to consider what communities stand to gain, and lose, when public participation is funneled through formalized legal processes, and what avenues environmental justice activists can explore to ensure that community members are meaningfully involved in decisions that intimately impact them.
Why Stop Grazing the Climate Commons?
Authors: Daniels Brigham
Published: April 2024

Many have argued that climate change is the textbook example of a tragedy of the commons. Assuming that is correct, to make headway on climate change, we would expect an enforceable agreement that provides for global collective action. The tragedy of the commons assumes that those who cut back when others do not are—to use the formal language of game theorists—suckers. So, the last thing we would expect is a surge of unilateral action. Contrary to theory, for the past decade, unilateral climate action has flourished among governments, businesses, other organizations, and individuals.

Is the number of climate suckers growing exponentially, or is there more going on? This Article proposes an alternative explanation. A growing and substantial part of the climate crisis is not subject to the tragedy of the commons, allowing rational actors to take climate action because of their self-interests, not despite them.

While the ability to rely on unilateral action to make some climate progress unlocks exciting possibilities, effectively confronting climate change requires a better understanding of why unilateral actors act. This Article exposes the economic and political incentives that frequently drive unilateral action. Understanding the incentives of unilateral actors opens two promising inroads for climate action: strengthening unilateral action by playing to these incentives and building on unilateral action to make collective action more obtainable.

O desgaste dentário é um fenômeno complexo resultante de hábitos prejudiciais e dietas inadequadas, levando a problemas como atrição, abfração, abrasão e erosão. A abrasão é um desgaste físico causado por hábitos, como roer unhas; a abfração, é uma perda patológica de estrutura devido a forças biomecânicas; a erosão, é a dissolução dos minerais dentários causado por fatores intrínsecos e extrínsecos. Já a atrição, é o desgaste fisiológico, que ocorre pelo contato excessivo dos dentes, podendo levar à perda de dimensão vertical e necrose pulpar em casos extremos. Necrose pulpar é a morte do tecido interno do dente, favorecendo a invasão bacteriana no canal radicular. O objetivo do presente trabalho é relatar um caso clínico de um paciente que compareceu a clínica apresentando múltiplos dentes com necrose pulpar e lesão periapical ocasionado por desgaste dental, sendo realizado o tratamento endodôntico de múltiplos dentes e encaminhado para conclusão do tratamento na disciplina de reabilitação oral e exodontia. O tratamento odontológico realizado resultaou de forma eficaz na resolução da sintomatologia dolorosa e na adequação do meio bucal do paciente.
Staatshaftung im Rahmen der Erfüllung sicherheitspolizeilicher Aufgaben durch Private
Authors: Selle Andrea
Published: April 2024

Die Haftung des Gemeinwesens für widerrechtliches schädigendes Handeln seiner Organe und Beamten im Rahmen der staatlichen Aufgabenerfüllung ist im Grundsatz unumstritten und in Bund und Kantonen weitgehend gesetzlich verankert. Damit wird der Staat auch für Schäden vermögensrechtlich verantwortlich gemacht, welche die Polizei anlässlich der Ausführung sicherheitspolizeilicher Aufgaben einer Person rechtswidrig verursacht. Handelt jedoch nicht der Staat selbst durch die Polizei, sondern wird in dessen Auftrag an seiner Stelle ein privates Sicherheitsunternehmen tätig, wird die Staatshaftung teilweise in Frage gestellt. Obwohl bei der Erfüllung staatlicher – und insbesondere sicherheitspolizeilicher – Aufgaben durch Private das Prinzip der haftungsrechtlichen Gleichstellung der geschädigten Person zu beachten ist, halten diesem Prinzip die in der Schweiz geltenden Staatshaftungsmodelle nicht immer stand. Ausgehend von der Feststellung, dass Private zunehmend in die Wahrnehmung staatlicher Sicherheitspolizeiaufgaben eingebunden werden, setzt sich der vorliegende Beitrag zum einen mit dem Vorgang einer solchen Privatisierung auseinander. Zum anderen analysiert und hinterfragt er die in diesem Zusammenhang vorgesehenen Staatshaftungsmodelle, und zwar mit Blick auf die Rechtsstellung der geschädigten Person und den schadensgeneigten Bereich, in dem private Sicherheitsunternehmen für den Staat tätig werden.
Rechtmässigkeit von Open Source-Ermittlungen durch Strafverfolgungsbehörden
Authors: Simmler Monika , Canova Giulia
Published: April 2024

Die Nutzung öffentlich zugänglicher Informationen („Open Source Information“) durch Strafverfolgungsbehörden mag auf den ersten Blick unproblematisch erscheinen, ist jedoch strafprozessrechtlich nicht unbedenklich. Die Bearbeitung von Personendaten im Rahmen von „Open Source Intelligence“ (OSINT) berührt Art. 13 Abs. 2 BV. Das Vorliegen einer Einwilligung durch die Veröffentlichung der Informationen schliesst die Qualifikation als Grundrechtseingriff nicht aus und lässt das Erfordernis einer gesetzlichen Grundlage nicht entfallen, reduziert die Invasivität der Massnahme aber deutlich. Wie diese Abhandlung darlegt, lässt sich allerdings nicht bei jeder OSINT-Methode auf eine Einwilligung schliessen. Einfaches und generatives Web Crawling sind von Web Scraping oder intelligenten Datenweiterberarbeitungen zu unterscheiden. Bei der Beurteilung der Invasivität von OSINT-Massnahmen sind ferner ihr Zweck, die Art der bearbeiteten Daten und zu überwindende technische Hürden einzubeziehen. Die Auseinandersetzung mit den strafprozess-, verfassungs- und konventionsrechtlichen Grundlagen zeigt, dass das geltende Recht nur minimalinvasive Open Source-Recherchen, nicht jedoch eingriffsintensivere Massnahmen abdeckt. Eine explizite innerstaatliche Regulierung wäre in Anbetracht der Praxisrelevanz dieser Ermittlungsmethode angezeigt.

Aim: The DNA of the atheroma is hypermethylated relative to adjacent healthy vascular tissue. A significant portion of hypermethylated loci in the atheroma DNA map to genes related to macrophage function. Reversing macrophage DNA methylation to physiological levels by targeting DNA methyltransferase (DNMT) activity may therefore slow atherogenesis. Here, the anti-inflammatory and anti-atherogenic activity of macrophage-targeted DNMT inhibitor SGI-1027 were tested.
Methods: SGI-1027 was encapsulated into human serum albumin (HSA) nanoparticle (HSANP) functionalized with the PP1 peptide, a macrophage scavenger receptor 1 ligand, fused to a FLAG epitope (S-HSANP-FLAGPP1).
Results: Nanoparticle physico-chemical characteristics predicted good marginalization towards the vascular wall, although SGI-1027 encapsulation efficiency was relatively low (~23%). S-HSANP-FLAGPP1 were rapidly internalized compared to non-functionalized and, surprisingly, functionalized void controls, and induced a shift towards an anti-inflammatory profile of secreted cytokines in human THP-1 macrophages. S-HSANP-FLAGPP1 colonized the atheroma and induced a significant ~44% reduction of atherosclerosis burden in the aortic tree of apolipoprotein E (ApoE)-null mice compared to controls. A reduction in aortic root atherosclerosis was observed, although primarily induced by HSANP irrespective of loading or functionalization. No alteration of body weight, non-vascular tissue gross histology, plasma glucose, triglyceride or cholesterol were observed. HSA whether free or structured in nanoparticles, induced a 3–4-fold increase in high-density lipoprotein (HDL) compared to vehicle.
Conclusions: Unexpectedly, effects that were likely non-epigenetic and induced by HSA per se were observed. HSANP loaded with SGI-1027 were anti-atherogenic but in an anatomical location-dependent fashion. SGI-1027 displayed a novel anti-inflammatory activity in non-proliferating THP-1 cells, implying that those effects are likely unrelated to DNMT inhibition. HSA elevated HDL per se, thus underlining a possible additional advantage of HSA-based nanocarriers.
Development of chia oil-in-water nanoemulsions using different homogenization technologies and the layer-by-layer technique
Authors: Julio Luciana M. , Copado Claudia N. , Diehl Bernd W.K. , Tomás Mabel C. , Ixtaina Vanesa Y.
Published: April 2024

Aim: The present study investigates the influence of various homogenization techniques, namely high-pressure valve homogenization and microfluidization, and different forms of modified sunflower lecithin, including deoiled (DL) and hydrolyzed (HL) variants, on the development of monolayer and bilayer nanoemulsions of chia oil.
Methods: Oil-in-water (O/W) nanoemulsions with 5% chia seed oil were prepared using simple (0.5% DL or HL) or double-layer [0.5% DL or HL and 0.3% chitosan (Ch)] stabilization. This involved a two-step homogenization process, utilizing either microfluidization or high-pressure valve homogenization. Chia oil nanoemulsions were characterized by their zeta potential, particle size, and rheological properties. Besides, their physical stability and omega-3 content during refrigerated storage were evaluated.
Results: Overall, the studied modified sunflower lecithin (DL and HL) demonstrated effective capability in stabilizing chia nanoemulsions and facilitating the formation of the double-layered structure following Ch deposition. Concerning the homogenization method, it has been demonstrated that under the same homogenization conditions, microfluidization resulted in significantly smaller droplet sizes and higher apparent viscosities compared to high-pressure valve homogenization. This discrepancy can be attributed to the design of the homogenization chambers, as microfluidization generates a narrow distribution of shear forces, while high-pressure valve homogenization yields a much broader distribution. In contrast to chia monolayer nanoemulsions, the nanoemulsions stabilized by modified sunflower lecithin-Ch demonstrated a noteworthy improvement in their overall stability. This enhancement can be ascribed to their increased apparent viscosity and the highly charged interfaces of the droplets. Furthermore, throughout the entire refrigerated storage period, the omega-3 content in all nanoemulsions remained unchanged.
Conclusions: In this study, mono and bilayer chia oil nanoemulsions were successfully obtained using modified sunflower lecithin and high-energy techniques. Microfluidization outperformed high-pressure valve homogenization, resulting in smaller droplets and increased viscosity. These findings are relevant for designing stable

REGIONALISM AND AFRICA'S FUTURE: THE IMPERATIVE OF UNITY
Authors: TENAW BIRHAN AEMRO , CHRISTOPHER NSOH
Published: April 2024

Africa has no choice but to integrate into the global economic and financial systems to grow sustainably and reduce extreme poverty. The challenges faced by a continent with numerous tiny national markets and landlocked states are seen as rational reasons for regional integration. As a result, African countries have signed numerous regional integration agreements, many overlapping significantly with their members. However, African regionalism has not made significant progress, and African disunity is one of its greatest challenges. Since the inception of Pan-Africanism, much has been said about African unity. Various scholars explain that PanAfricanism is a movement, an ideology, and a geopolitical project that liberates and unites African people and the African diaspora worldwide. Kwame Nkrumah and Julius Nyerere are two of the most famous ideologues of African unity. They shared the desire and ideal that the strength of Africa would come from a 'United States of Africa'. At the Ghana Conference in 1960, Nkrumah said that Africa could and must be united, but it was not easy, and came up against numerous obstacles. Therefore, all the concerned bodies on the continent need to sit down and plan for the future, knowing that the only way out of the crisis lies in realizing true African unity. This paper examined the impact of African unity on the effectiveness of regionalism and a better future for the continent.

DIGITAL TECHNOLOGY'S EFFECT ON TEACHING AND LEARNING
Authors: MANAFF NORSHAHRA ABDULL , HALABI AZAHARI MUSTAFFA
Published: April 2024

Digital technology has had a big impact on how teaching and learning are done in different areas of education. It has been demonstrated that incorporating educational technology into teaching and learning procedures improves their efficacy (Qurat-ul-Ain et al., 2019). According to Qurat-ul-Ain et al. (2019), it is essential for raising productivity, efficacy, and pedagogical advancements that are beneficial to education. Interactive learning experiences are made possible by educational technology, which offers new ideas and uses beyond simple digital resource storage and transfer (Tuma et al., 2021). Furthermore, by providing a variety of learning opportunities and encouraging co-creative thinking abilities, digital technologies have been shown to support collaborative creativity in language instruction (Sastre et al., 2022). Even while technology offers many advantages, there are still issues with how to integrate it into the classroom. According to several studies, it's critical that teacher educators act as role models and encourage educators to use technology (Matthew et al., 2002). Furthermore, emphasis has been placed on the role that educational leaders play in helping students acquire digital citizenship and technology use (Baydar, 2022). In order to maintain teaching and learning as the primary focus in the face of technological improvements, schools must establish technology leadership. (In Davies, 2010). Moreover, the integration of technology in education has been linked to favorable consequences, including expedited and effortless learning and the promotion of inclusive, sustainable education (Uygur et al., 2020). Divergent viewpoints exist about the efficaciousness of technology in education. While some contend that technology can augment learning, others maintain that specific domains of knowledge, such as physical education, cannot be satisfactorily imparted through technological means (Aprilo et al., 2023). All things considered, incorporating technology into education necessitates a thorough comprehension of both its possible advantages and disadvantages, highlighting the necessity of ongoing professional development and assistance for teachers (Karakaş & Hidiroğlu, 2022).

El asma fue descrita por primera vez por el médico griego Hipócrates y deriva de la palabra griega asthamaino que significa jadeo. La Iniciativa Global para el Asma (GINA) define al asma como un síndrome caracterizado por limitación variable del flujo de aire espiratorio, hiperreactividad de las vías respiratorias e inflamación crónica de las vías respiratorias. Esta enfermedad afecta al 1 - 29% de la población mundial. Es la enfermedad crónica más común de la infancia. En los últimos 20 años las cifras de nuevos casos han aumentado. Se puede clasificar según su fenotipo en: Tipo 2 alto y Tipo 2 bajo también conocido como Th1 alto y Th1/Th17 alto. Según su endotipo dependiendo a la gravedad y sintomatología en leve, moderadamente grave y severa o que amenaza a la vida. El diagnóstico es fundamentalmente clínico, las pruebas complementarias de función pulmonar sirven de apoyo y son confirmatorias. El cuadro clínico característico es tos, sibilancias, opresión torácica y en cuadros graves se observa la dificultad respiratoria siendo la sibilancia es el síntoma más característico. Dentro de lo que respecta al tratamiento, se basa fundamentalmente en prevenir los síntomas, minimizar la morbilidad de los episodios agudos y prevenir la mortalidad, dando medidas confortables que permitan el desarrollo psicológico, laboral y académico de las personas que lo sufren. El presente documento describe un enfoque total de la enfermedad desde su inicio fisiopatológico hasta el tratamiento, con un enfoque actualizado en los últimos consensos de la GINA y la actualización bibliográfica.

La dinámica de sistemas se utiliza para abordar el problema de los microplásticos en la atmósfera y sus efectos para el medio ambiente. Este enfoque implica la creación de un sistema que tenga en cuenta interacciones entre la deposición atmosférica, la retención de musgo y los impactos en el páramo. Se identifican factores como la absorcion de microplásticos y la concentración de estas partículas en la atmósfera. Los hallazgos abarcan varios escenarios, que van desde las condiciones iniciales hasta mejoras en la capacidad de retención, la sensibilidad de los páramos, la dispersión de microplásticos y la consecución de una tasa de absorción del 90% por parte del musgo. Estos resultados subrayan el papel vital en la mitigación de la contaminación del aire. La utilización de la dinámica de sistemas se demuestra como un instrumento eficaz para comprender la intrincada dinámica entre la deposición atmosférica y su acumulación. Al modelar variables y relaciones esenciales, este enfoque holístico no solo ayuda a determinar la cantidad y composición de los microplásticos, sino que también permite proyectar posibles escenarios a largo plazo. Esta combinación de musgos y dinámica de sistemas se establece como una estrategia confiable para abordar el impacto ambiental de los microplásticos mediante el examen de la deposición atmosférica.
Estudio de las Interacciones Químico-Cuánticas de la Semejanza entre el Ácido Elágico (Punica Granatum) y la Ciclofosfamida
Authors: González Pérez Manuel
Published: April 2024

La ciclofosfamida (CFM) se ha estudiado como agente quimioterapéutico durante muchos años. Esta investigación tuvo como objetivo estudiar las interacciones cuánticas-químicas in silico del ácido elágico (AEL) y su similitud con el CFM. La teoría del coeficiente de transferencia de electrones se utilizó como base para calcular el equivalente en radios de Bohr (a°). La distancia calculada es el equivalente al salto HOMO-LUMO de un electrón desde la molécula A1 a la molécula A2 si ambas moléculas son de la misma especie y el salto de A1 a B2, si la interacción es de la especie A a una especie B diferente (bandas cruzadas). Se encontró similitud entre las dos sustancias CFM y AEL. Un diagrama de bigotes muestra los coeficientes de transferencia de electrones de las dos sustancias (CTE) en interacciones con los AAs. Estas interacciones presentan dos patrones de oxidación-reducción similares; parecen ser diagramas paramétricos. Los diagramas debajo del pozo cuántico son del CFM y los diagramas de reducción de óxido del AEL están arriba. Por lo tanto, se concluye que el CFM oxida con mayor poder que el AEL, por lo que el AEL es menos agresivo que el CFM.

Las competencias laborales de los prestadores de servicios turísticos son un factor clave en el desarrollo y calidad dentro de la actividad, por lo que la importancia de contar con personal calificado, debe ser prioridad para quienes administran los establecimientos. Es por ello, que el presente proyecto de innovación busque plantear políticas y estrategias para que los bachilleres afines al turismo de la UECT graduados en el periodo 2018-2023 se inserten en el campo laboral de la ciudad de Tena, e incidir en la mejora de la calidad del servicio en las empresas turísticas desde esa perspectiva. Con la información otorgada por la Institución Educativa y el Ministerio de Turismo, se levantó el diagnóstico de la situación laboral de los bachilleres, utilizando el método descriptivo y el análisis cualitativo y cuantitativo, mediante encuestas y entrevistas. Del análisis de los datos obtenidos se evidencian resultados poco alentadores que revelan el deficiente porcentaje de inserción de los bachilleres objeto de estudio. Además, se conocieron cuáles son los factores que demandan las empresas para contratar personal, permitiendo definir políticas y estrategias de inserción laboral para mejorar la calidad del servicio turístico.

Desigualdad de género al Otorgar las Licencias de Paternidad en las Fuerzas Armadas de México
Authors: Ocampo Domínguez Diana Nicole
Published: April 2024

La investigación se enfoca en entender por qué la licencia de paternidad no está regulada en la Ley del Instituto de Seguridad Social para las Fuerzas Armadas, a pesar de que la Ley General para la Igualdad entre Mujeres y Hombres promulgada en 2006 busca garantizar la igualdad de oportunidades, se argumenta que la falta de regulación refleja desigualdades de género y un enfoque tradicional en el que se espera que las mujeres asuman principalmente las responsabilidades de crianza, sin embargo, los cambios sociales y la conciencia sobre la paternidad responsable han llevado a una mayor participación de los hombres en las tareas domésticas y de cuidado. La falta de reconocimiento de la licencia de paternidad en esta ley específica refuerza estereotipos de género y limita la igualdad en la crianza y las responsabilidades del hogar, en las últimas décadas se han producido cambios sociales y políticos como la visibilidad de las demandas de los movimientos feministas sobre los trabajos del cuidado, la transformación gradual de los roles que ocupamos mujeres y varones en las familias, el nuevo escenario de diversidad familiar y otros cambios. Si bien se han producido cambios normativos, gran parte de estas normas han quedado atrás en términos de igualdad entre el hombre y la mujer como [1]así también los nuevos modelos familiares y cuidado equitativo respecto a la crianza compartida, a esta situación se suma, el dejar fuera de esta labor a los hombres, pues de acuerdo con el marco legal de la Ley del Instituto de Seguridad Social para las Fuerzas Armadas, los hombres por su tipo de labor no pueden gozar de la licencia de paternidad, reforzando así la idea de que su rol es especial y así justificar que no pueden pasar tiempo con sus familias, la extensión de los permisos de paternidad, entre otras cosas, constituiría un instrumento para fomentar una mayor igualdad entre las mujeres y los hombres en el cuidado de sus hijos y, en ̇última instancia, en el reparto de las tareas del hogar y avanzar de este modo, con la conciliación de la vida laboral y familiar de las madres/padres, o la atenuación de los estereotipos de género.  La investigación busca abordar y promover un mayor equilibrio en la distribución de roles de cuidado entre hombres y mujeres, siendo está una reforma laboral que genere la igualdad en el otorgamiento de derechos para madres/padres en cuanto a las licencias, lo cual es una herramienta fundamental para lograr romper con los roles de género patriarcales, y así poder proteger a las familias y niños a través de una responsabilidad familiar compartida.
