Published: January 2022

Stress is a humanitarian symptom that often receives considerable attention in management stress literature. Latest studies found that uncontrollable online work stress levels may intensify job interference on family well-being. Even though this relationship has been extensively studied, the effect size of online work stress elements as an important independent variable is not thoroughly discussed in organizational stress literature. Thus, this study aims to assess the relationship between online work stress and interference of job affairs on family well-being. A purposive sampling plan was utilized to gather data from 160 usable questionnaires from employees at a public service organization in Peninsular Malaysia. The SmartPLS path model analysis outcomes displayed three essential outcomes. First, the relationship between responsibility ambiguity and enhanced interference of job affairs on family well-being was significant. Second, the relationship between responsibility conflict and interference of job affairs on family well-being was significant. Third, the relationship between responsibility overload and interference of work affairs on family well-being was significant. This outcome confirms that the inability of employees to appropriately control online work stress can intensify the interference of job affairs on family well-being. Thus, this study can be used as important guidelines by practitioners to understand diverse perspectives of online work stress concept and formulate user-friendly based online work practice to enhance organizational performance during the Covid-19 pandemic. In addition, the discussion, implications, and conclusion of the study were elaborated.

Based on a low time-domain-instability narrow-linewidth seed and a counter-pumped power-amplifier with a 20/400 μm core/inner-cladding-diameter active fiber, an all-fiber 2.02 kW and 4.7 GHz linewidth near-diffraction-limited master-oscillator power-amplifier (MOPA) laser at 1064 nm is demonstrated experimentally. By decreasing the time-domain-instability of the signal, the stimulated Raman scattering effect in the power-amplifier stage is suppressed effectively. As a result, a measured M2 factor of 1.20, and an optical signal-to-noise ratio of >65 dB are obtained at the maximum output power without observation of the transverse mode instability effect. The further enhancement of power scaling of this MOPA laser is restricted by the stimulated Brillouin scattering effect. To the best of our knowledge, this result exhibits the highest output power of all-fiber MOPA laser with narrow linewidth (<5 GHz level), which is highly competitive in spectral beam combining.

The main factor that affects the parameters of the workings of humidity in the baby incubator is the sensor used to read the humidity in the room. The purpose of this study is to analyze the humidity sensor in the baby incubator using 2 humidity sensors (DHT11 and DHT22) in the different location. The manufacture of this device used an after-only design, with a comparison device of INCU Analyzer, DHT11, and DHT22 sensors. Based on the measurement, DHT11 produced a value of 46%, while DHT22 produced a value of 55.45% with BPFK standards of 50%-70%. Based on the results of measurements using the INCU Analyzer, the average error value for DHT11 is 16.05%, while DHT22 is 3.47%. Therefore, the results showed that the DHT22 sensor was more accurate to be used in baby incubators because the measurement results were under BPFK standards and produced a low error value. This can be further implemented in a baby incubator making to improve the health and safety of the babies

Failure is something which causes services on the cloud to go down for some time period. Most of the times instead of recovery and repair, we opt for virtual machine migration where failover of the failed service is done on some other running virtual server so that the service is revived. Virtual migrations and recovery mechanisms consume a lot of energy and many approaches are implemented to make them energy efficient. Failure Detection is a topic of equal importance and comes under fault tolerance. Failure detection if done properly can be more effective and energy/cost saving than fault recovery. Heartbeat strategy is one such failure detection approach where live processes send an “I am alive” message to the host device at some pre-defined fixed intervals which ensures that the process is running fine. In this paper, we propose to mark the nodes whose processes have failed to send the heartbeat message and prepare a count (confidence factor, α) for the same. In primary testing, if this confidence factor reaches a specific threshold then that particular node is sent for confidence testing (second level failure detection testing using a different time sequence of heartbeat message arrival) and later marked for failure recovery (if found faulty). Fault recovery techniques are then applied to it so that it can be corrected and reused and the current jobs can be migrated to the better node during the recovery period. If the confidence factor, α is below the threshold value then no action is taken and only network parameters and connections can be rechecked. This method will re-ensure the trust on heartbeat strategy for fault detection and save the device from failure.

The province of NTB has a beautiful island which in 2017 was named a World Halal Tourism Destination. The island is known as the "island of a thousand mosques" not only because the population is predominantly Muslim, but more than that, the people of this island have high enthusiasm in establishing places of worship in the form of mosques and prayer rooms as well as Islamic educational institutions which we later know as Islamic boarding school. There are recorded more than 300 Islamic boarding schools spread across this small island until 2019. This small island is known as the island of Lombok where the existence of Islamic boarding schools as formal and non-formal educational institutions, with all its distinctive roles in the form of; first, as a center for the transmission of Islamic sciences; second, maintaining the continuity of Islamic tradition; and third, as a center for the reproduction of scholars. All of these distinctive roles are consistently carried out by the boarding school community, namely Tuan Guru and santri, while maintaining their Islamic identity without discarding the local wisdom where the boarding school is located, these distinctive and unique characteristics have widely led boarding school as agents of socio-religious change.
Le responsabilità e il ruolo degli agenti di destabilizzazione nella transizione verso la sostenibilità: un framework teorico
Authors: Grasso Marco , Randelli Filippo
Published: January 2022

Since it is not beneficial to everyone, the sustainability transition is a complex process and many mechanisms hinder its evolution. Some agents involved in this transition shoulder significant costs and burdens: even if some agents can shoulder part of them, it is unlikely that all agents will spontaneously comply with the responsibi-lity that the sustainability transition imposes on them. This paper intends to investigate how, in the context of the sustainability transition, the relevant agents must/can comply with the duties demanded by this responsibility (which can be defined as “first order” responsibility). Indeed, some agents do not comply with their own (first order) responsibility and with the consequent obligations. To induce such (first order) agents to act in accordance with their (first order) responsibility, the notion of “second order” responsibility – that is, the responsibility that other agents ensure that the first order agents act on the basis of their (first order) responsibility – should be employed. In this normative perspective, the work proposes a theoretical-analytical framework within which second order agents – which in a pragmatic perspective can be defined as “agents of destabilization” (divided into primary and operational) – take action to win the resistance of first order agents in order to favor the sustainability transition.
Aspetti geografici del confronto fra sapere esperto e contestuale: un’analisi regionale nei paesaggi del “degrado”
Authors: Bressan Giorgia , Guaran Andrea , Visentin Francesco , Zaccomer Gian Pietro
Published: January 2022

Negli ultimi decenni la partecipazione attiva degli abitanti per l’interpretazione, la gestione e la pianificazione del paesaggio ha assunto un ruolo sempre più rilevante, grazie agli indirizzi proposti dalla Convenzione europea del paesaggio che individua l’esperienza e il sentire delle popolazioni come una fondamentale fonte informativa. Nonostante le difficoltà implicite nella valorizzazione di una simile fonte, il confronto tra il sapere contestuale ed esperto può favorire l’elaborazione di nuove conoscenze, a patto che si possano confrontare le informazioni e mettere in effettiva e fruttuosa comunicazione i due saperi.
During the last decades, the active participation of the inhabitants in the interpretation, management and planning of landscape has assumed an increasingly important role, thanks to the challenges and understandings provided by the European Landscape Convention which advocated the participation and enhanced the role of the populations as fundamental sources of information. Despite the difficulties linked to the valorization of such assets, the comparison between expert and public views can favour the production of new knowledge as long as these information and sources could be compared and connected through fruitful approaches. The present contribution finds his roots in the development of Friuli Venezia Giulia Regional Landscape Plan and, adopting a participatory approach, tried to investigate the perceived landscapes of risk and degradation. The focus is on three categories of areas and sites perceived as degraded, specifically those resulting from the massive presence of abandonment former military areas, hydrogeological problems and, finally, quarry activities. After presenting the most relevant aspects and the results of the geo-cartographic analysis, the limits and opportunities of the research are highlighted. On the one hand, similarly to other participatory projects, the analysis presents problems in terms of quality and territorial coverage, on the other hand, it offers reflections on the possible synergies between local and expert knowledge.
Rewriting Marx to expose the data society and AI
Authors: Diana Stefano
Published: January 2022

As I show with examples from the Grundrisse and the Capital, some fundamentals of Marx’s critique of political economy can be rewritten with simple substitutions to yield surprisingly pertinent analyses of today’s “information society” and the role that data and AI play in it. The reason behind this strange phenomenon is that Marx’s penetrating study of money as a dehumanizing abstraction and self-replicating capital can be extended with minor changes to the main abstraction and “automatic fetish” of our historical regime: digital data. As money-capital tends to grow by itself independently of humans, so does data. AI is the main engine of this new dangerous cycle.
Il governo dell’informale come problema di egemonia
Authors: De Nicola Alberto
Published: January 2022

This paper intends to propose a critical examination of some of the theoretical orientations that have most characterized the debate on the informal economy in recent years. The reflection will take welfare regimes as a research field for analyzing the impact of informality on institutional systems. The paper will be divided into two parts. In the first one, structuralist, geographical and governmental approaches to informality will be discussed, showing some theoretical limits in their interpretation of the plurality of social practices and institutional change. In the second part, some indications will be proposed on how to understand the role of informality on institutional systems starting with a review of some Gramscian notions relating to the problems of normativity and historical change.
Un cuscinetto chiamato informalità. Politiche, simboli e materialità di un “segreto”
Authors: Saitta Pietro
Published: January 2022

This essay explores the semantics of the term “informal economy” and, in particular, the relation between the two words. It shows how this subject is anything but something with no form and no structure. Moreover, it reflects on the historical relations between this type of economy and the cyclical transformations of capital. Informal economy is seen as a buffer that makes such changes both socially bearable and symbolically necessary – in order to produce alliances between classes and mobilize different sentiments in given circumstances. The example of (neo-)populism(s), especially in a Southern Italian city (Messina), is provided and shortly discussed. Finally, it advocates descriptions of the phenomenon that unfold the substantial overlapping of what is official and “secret”, and is in fact part of the experience of millions of people in an endlessly changing world.

Desde o decreto nº 5.154 de 23 de julho de 2004, que permitiu o retorno do Ensino Médio Integrado ao Técnico, até a lei nº 13.415 de 16 de fevereiro de 2017, que possibilitou novos arranjos curriculares de forma integrada entre o Ensino Médio e Técnico, vivemos mudanças no Ensino Médio Profissional das Escolas Técnicas da rede do Centro Paula Souza do Estado de São Paulo. E, diante desse cenário, trazemos recorte de uma pesquisa de mestrado que, analisando a racionalidade subjacente à implantação do Novotec Integrado, focou as relações que se estabelecem com a matemática no currículo, o discurso expresso nos documentos oficiais do Centro Paula Souza e as discussões promovidas em um grupo de professores que atuam nos cursos implantados. A pesquisa foi realizada em uma Escola Técnica Estadual (Etec) que implantou, em 2020, o Novotec Integrado em dois cursos distintos: Ensino Médio com habilitação de Técnico em Administração e Ensino Médio com habilitação de Técnico em Marketing, organizados de acordo com a nova Base Nacional Comum Curricular (BNCC). Neste artigo discutimos as percepções de um grupo de docentes de Etecs sobre essa implantação. Em termos metodológicos foram realizadas reuniões via plataforma digital, as interações dialógicas foram transcritas e divididas em cinco episódios. Na sequência, a partir dos cinco episódios, foram constituídas mônodas com inspiração em Walter Benjamin e analisadas seguindo os pressupostos da Teoria Crítica. Como resultado apresentamos narrativas de docentes que evidenciam como a implantação do Novotec Integrado foi pautada em racionalidade instrumental, orientada a fins técnicos e estratégicos, e sem espaços para participação dos docentes da escola na elaboração da proposta.

En este contexto, el objetivo de este trabajo es presentar una revisión bibliográfica sobre modelamiento de carga, en la cual se prioriza las investigaciones de la última década. Para lograr el objetivo precitado primero se propone, a conocimiento de los autores, la primera metodología sistemática de clasificación bibliográfica enfocada específicamente al modelamiento de carga. En base a esta metodología se deducen los resultados que incluyen: tendencias actuales de investigación, áreas poco investigadas y nichos futuros de investigación; estos resultados son claramente descritos y resaltados.
Auditoría energética a un bloque de aulas en Quito, Ecuador como estrategia de reducción de emisiones de CO2
Authors: Rueda Víctor
Published: January 2022

Esta investigación busca conocer el consumo de energía en el Bloque A del Campus Sur de la Universidad Politécnica Salesiana, en Quito – Ecuador, a través de una auditoría energética, misma que analiza su envolvente térmica, la eficiencia de los equipos térmicos instalados y así conocer su actual calificación energética simulando su ubicación en España, país que cuenta con herramientas informáticas para este fin. Los resultados de ese trabajo ayudarán a instituciones públicas y privadas relacionadas al área a impulsar la creación de una herramienta informática de calificación energética de edificios, exigido en la Ley de Eficiencia Energética aprobada en el año 2019 en Ecuador.

Para esto se recopiló información sobre parámetros climáticos, datos de la envolvente, instalaciones térmicas, entre otras. Después mediante el programa HULC, se emitió la calificación energética del edificio, misma que fue E. Posterior a esto se propuso mejoras de eficiencia energética. Mediante la simulación de estas mejoras, incluyendo la energía solar térmica, se redujo en un 60% el consumo de energía primaria (EP) no renovable y las emisiones de CO2, logrando una calificación energética final A.

Este trabajo podrá ser mejorado si se llega a contar con información más robusta que ayudará a optimizar la simulación en HULC e impulsa investigaciones sobre auditorías energéticas en edificios relacionadas con los consumos de EP no renovable y emisiones de CO2.

Resumen

En este artículo se presenta una propuesta metodológica para el cálculo de la energía firme de centrales hidroeléctricas, considerando curvas de duración mensuales de caudal y un enfoque estocástico en lugar del enfoque tradicional determinístico. Esta implementación metodológica demostró, que la incorporación de las curvas mensuales de duración de caudales y la consideración de la naturaleza estocástica del recurso hidrológico, maximiza la oportunidad de participación de centrales hidroeléctricas privadas habilitadas como autogeneradores para la suscripción de contratos bilaterales con grandes consumidores; aspecto que permitirá a la ARCERNNR contar con información técnica de base para ajustes normativos que se requieran para la Regulación Nro. ARCONEL  004/17 “Regulación para Grandes Consumidores”.

Como parte del estudio, se realizó además un análisis estadístico de la producción energética de autogeneradores, autoconsumos y entrega de excedentes de energía de los autogeneradores, con el fin de conocer la situación actual de los autogeneradores y evaluar futuros ajustes a las condiciones establecidas en la regulación “001/14 - Participación de Autogeneradores en el Sector Eléctrico”. Adicionalmente se analizó la confiabilidad de abastecimiento energético del sistema considerando la operación de autogeneradores y el abastecimiento de consumos para un horizonte de 7 años, bajo escenarios de hidrología diversos. Para el desarrollo de este trabajo se utilizó el modelo computacional SDDP.
Auto – Conversores Sincrónicos: Emulación de Generadores Sincrónicos con Conversores para la Inyección de Inercia Virtual en Sistemas de Potencia de 60 Hz Considerando Auto-sincronización
Authors: Riofrio Jonathan , Farkas Csaba
Published: January 2022

La generación de electricidad a partir de fuentes renovables y la integración de las redes eléctricas inteligentes son tendencias en la actualidad de los sistemas eléctricos de potencia. Sin embargo, estos están intensificando la falta de inercia durante la operación de los sistemas modernos. Esto ha conllevado a la aparición de nuevas técnicas que buscan emular la inercia de los sistemas digitalmente, y así resolver esta limitación operativa. Una de estas técnicas es la denominada como conversores sincrónicos (CS) que busca replicar la operación de un generador sincrónico (GS) utilizando conversores CC/CA. De hecho, un SV permite que los sistemas eléctricos de potencia controlen las plantas de energía renovable conectadas a la red y evita la pérdida de estabilidad de voltaje y frecuencia durante su operación. Esta investigación presenta una variación del modelo original del SV, la misma que es capaz de auto sincronizarse con la red antes de su conexión, y además rastrear la frecuencia de la red después de esto. De igual manera, el circuito de potencia del SV ha sido modificado para incluir una planta fotovoltaica (FV) y un controlador de seguimiento del punto de máxima potencia (MPPT) como fuentes de voltaje en CC. Esto junto con el cálculo de los parámetros del SV para una frecuencia de 60 Hz brinda novedad a esta investigación. Finalmente, las simulaciones en MATLAB confirman una operación confiable del SV propuesto ante variaciones de potencia activa (P) y reactiva (Q) en una red de prueba.
OPTIMIZATION OF THE SOWING METHODS FOR CULTIVATION OF FOENICULUM VULGARE (COMMON FENNEL) AS A NICHE CROP
Authors: Stotska Svitlana
Published: January 2022

Research findings are given herein concerning Foeniculum Vulgare (common fennel) sowing method optimization with the implementation of the organic cultivation technique in a climate of the Polissia region, having an impact on the targeting of the main crop outputs. Common fennel is grown mainly in the southern and western regions of Ukraine. However, an option to grow fennel in a climate of the Polissia region has become real because of changes in the climatic conditions. The demand for domestically made products involving niche medicinal herbs has grown significantly in these recent times. Common fennel is known to be among the most popular niche medicinal crops. At the same time, a demand arose for increasing crop cultivation areas, as well as geographical spread thereof. It is found that the implementation of a wide-row sowing method (60 cm) has contributed to the increased seed yield of common fennel. Maximum gain in green weight of common fennel has been noted during main vegetative phases of the crop sown with a wide-row technique (60 cm), i.e. 2,471 g/sq.m in blooming period. The photosynthetic activity of fennel plants has been varied with exposure to the factor investigated. Assimilating leaf area of common fennel was ranged from 24.2 to 25.5 thousand sq.m/hectare, photosynthetic potential: from 1.512 to 1.685 million sq.m / hectare * 24h, and net photosynthetic productivity: from 3.39 to 3.65 g/sq.m * 24h. Implementation of the ordinary row sowing method (15 cm) negatively affected both the development of photosynthetic activity and the yielding ability of common fennel seeds.
Over the years of research (2017-2019), the highest yield of common fennel seeds, i.e. 0.96 T/hectare (on average) was achieved with the crop sown with rows spaced 60 cm between each other. Due to the said option, the highest possible yield of dry matter (6.10 T/hectare) was achieved, thus providing for the gain of 1.13 tons per hectare.
