The IMPACT of FAMILY SOCIAL CAPITAL on RESOURCE DEPLOYMENT in CHINESE ENTREPRENEURIAL FIRMS
Authors: Woods Jeremy Alan , Sweida Gloria , Burley Peter , Fang Hanqing "Chevy" , Xu Zhenning "Jimmy"
Published: December 2022

One of the most important determinants of performance for any firm is the unique bundle of resources the company possesses. To date, however, empirical results on whether “familiness” as an element of this resource bundle has a positive or negative impact on firm performance have been mixed (Dyer, 2018; Gottardo & Moisello, 2019; Oswald et al., 2009; Pitchayado et al., 2018). This paper employs structural equation modeling to examine how entrepreneurs in China’s Zhejiang Province include members of their nuclear families, extended kin networks, and professional networks in their top management teams to access different bundles of family and non-family human resources, leading to variance in firm performance results. We find firms that leverage “guanxi” (a particular concept of kin, common in China but not often employed as a construct in western-based research, which encompasses both extended family members and close friends) for industry, technical, or entrepreneurial expertise enjoy certain types of higher performance results. In comparison, firms that leverage nuclear family members for management or marketing expertise achieve certain types of lower performance results. Post-hoc analysis indicates that leveraging guanxi specifically for prior entrepreneurial experience or for technical expertise leads to greater employee growth and higher subjective assessment of success. Conversely, leveraging nuclear family members for management or technical expertise leads to lower levels of these same performance variables. However, only firm size, measured by number of employees at venture founding, is predictive of revenue growth.

Authors: Curado Carla , Jesus Maria , Bontis Nick
Published: December 2022

The goals of this study are to explore the use of the Management Control Systems (MCS) by SMEs’ managers at the country level in order to identify the importance given to financial and nonfinancial measures, as well as key performance indicators. In this study, we use the behavioral accounting lens and adopt mixed methods approach to study the use of the MCS in Portuguese small to medium enterprises (SMEs): a correlational and a configurational analysis. Data was collected from a cross-sectional survey of 414 top managers of Portuguese SMEs across several industries. The results show that managers’ perceptions of the importance given to financial measures is positively and significantly related to the importance given to several nonfinancial measures. We take an original approach by addressing the managers’ perceptions to contribute to the understanding of Portuguese SMEs’ use of tools for strategy implementation: the use of different MCS. Additionally, the study discovers alternative configurations of individual and organizational conditions that lead to the managers’ perception of the importance given to financial and nonfinancial measures. This paper offers support for SMEs based on controlling strategy implementation by using MCS. The study’s limitations regard a relatively low response rate to the questionnaire (4.56%), which may be justified because data was collected during the COVID-19 pandemic. We offer alternative configurations that generate the perception of managers about the importance of using financial and nonfinancial measures. Our results enlighten the use of such tools in support of strategic accomplishment.

Authors: Afeltra Giovanna , Alerasoul Sayed Alireza , Minelli Eliana , Vecchio Yari , Montalvo Carlos
Published: December 2022

Sustainable Development Goals (SDGs) have gained importance and the world is moving on a sustainability trajectory, which requires organisations to balance financial, environmental, and social dimensions of management. Companies are encouraged to adopt sustainable innovations that include resource efficiency, waste reduction, energy use, responsible behavior etc., to overcome environmental issues and incorporate societal aspects. However, the types of innovations that embrace the so-called triple bottom line philosophy have been tenuously investigated in relation to organisational performance of firms. Through an empirical study, this work investigates the relationship between sustainable innovation in its three dimensions and organisational performance, including stakeholder management, human resource management and process measures, in the context of Italian manufacturing companies. The results show that a greater emphasis on sustainable innovations has a positive impact on the organisational performance and competitive advantage of firms, revealing the key role of human capital and portraying important avenues for future research.

Authors: Alaksanasuwan Siriwat , Buranawong Adisorn , Witit-anun Nirun
Published: December 2022

The structural and oxidation behavior of nanocomposite titanium chromium nitride (TiCrN) thin films has been investigated by using x-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDS), and field emission scanning electron microscopy (FE-SEM). The TiCrN thin films were deposited on Si substrates by using the reactive DC magnetron sputtering technique from the Ti-Cr mosaic target. After that, the as-deposited thin films were annealed in the air at 500 - 900°C for 2 h. The XRD results showed that the formation oxidation of anataseTiO2, rutile-TiO2, and Cr2O3 which diffraction peak appear from 500°C. The relative intensity of these oxide peaks varied with the annealed temperatures. By observing from FE-SEM, the aggregation of the grain increased with the annealing temperature. The cross-sectional results showed that the thin dense oxide overlayer occurred at 700°C and the oxide thickness increased gradually with the annealing temperature. Meanwhile, underneath the TiCrN grain grew above 700°C and become more void structure after annealing at 700°C. The dramatically increase of the oxygen content was found at 700°C and the evolution of Ti, Cr, N, and O with different elements compositions at various annealing temperatures were investigated from the EDS technique. The oxide layer obviously grows inward indicating the oxidation of TiCrN thin films belongs to inward oxidation. The oxidation rate of the films was increased with the increase of annealing temperature. The activation energy of the oxidation as evaluated by the Arrhenius-type relation was 168 kJ/mol.

Published: December 2022

Cellulose nanofibers (CNF) are materials synthesized from wood-based fibers having excellent mechanical properties due to their high crystallinity. In this research, the cellulose nanofibers were synthesized from bamboo fibers, as the abundant natural fibers available worldwide. The cellulose nanofibers had been synthesized using chemical processes of bleaching with acetic acid and sodium chloride, followed by alkaline treatment with sodium hydroxide, and acid hydrolysis with sulfuric acid combined with mechanical process in ultrasonic bath. Isolation of nanocellulose from bamboo scrap raw material was confirmed by different analysis methods. The morphology of CNF was characterized by using a scanning electron microscope (SEM). Fourier transform infrared spectrometer (FT-IR) and X-Ray Diffractometer (XRD) examined chemical structure and identified the crystallinity of nanocellulose materials. The monofilament of cellulose nanofibers was prepared by using a wet spinning process. The effects of coagulating solvent, water, methanol, acetone, and calcium chloride (CaCl2) on monofilament formation were studied. Morphology study of CNF monofilament was carried out using a digital camera to observe the spinnability of the monofilament and the relationship with wet spinning process conditions. The thermal properties of the nanocellulose spun in methanol and acetone as coagulation solvent were analyzed by differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA). Also, the measuring of degradation temperature of nanocellulose spun compared with the nanocellulose extracted.

Introducción: términos críticos de Elena Altuna sobre el discurso colonial
Authors: Teglia Vanina María
Published: December 2022

Este dossier que aquí publicamos en la revista Recial de la Universidad Nacional de Córdoba, Argentina, responde a una deuda que teníamos con una crítica de Salta, muy creativa, ciertamente, seria en sus planteos y rigurosa en la investigación, además de muy dedicada. Siempre valió la pena escuchar y leer a Elena Altuna, porque aprendíamos y porque lo que proponía y analizaba era interesante y comprometido con las personas, la escritura y la vida. Así también, y a decir verdad, Altuna parecía siempre dialogar con los actores implicados, como si estuviera metida en la escena del documento y a la que lograba hacer presente, lo que no significaba que consintiera con los personajes, con sus actos y sus ideas. Para consolarnos en algo y también hacer presente a Elena —si puedo—, quiero entonces, sin más prólogos, exponer aquí un sumario de algunos de sus aprovechables conceptos e ideas más llamativas sobre los documentos coloniales que abordó o aquellos que más recordamos, por el momento, al menos.A partir de una extensa lectura de memoriales, pero también del archivo colonial extendido, Altuna analizó y describió, en varias ocasiones de su vida académica, una retórica de “las cosas de Indias” emergente en los siglos XVII y XVIII. Los viajeros o caminantes coloniales conformaron esta retórica y ella finalmente contribuyó con la formación de la conciencia criolla en situación colonial. Es decir, la crítica salteña logró relevar los alcances de un discurso que, por un lado, respondía a los modelos descriptivos incluidos en los interrogatorios de la Corona española destinados a los viajeros o caminantes, pero que, por el otro, genérica, temática y estilísticamente, concluyó desplegando formas propias, aunque dependientes aún de la situación colonial.
Elena Altuna: lectora de José María Arguedas
Authors: Escobar-Albornoz Juan
Published: December 2022

El trabajo crítico de Elena Altuna se adscribió al periodo colonial americano, específicamente al área andina, pero su “punto de hablada” como diría Ortega y Gasset, trasciende las fronteras de época y las limitaciones de área cultural. Como una de las figuras destacadas de una tradición crítica profundamente original, la estudiosa argentina ayuda a conformar una generación de renovación de la crítica latinoamericana, situando su trabajo en horizontes históricos de larga duración que tienen puntos de contacto, articulación y continuidad a lo largo de los periodos de la historia cultural americana. Esto explica la atención que Altuna ̶̶ experta en el periodo colonial ̶̶ le prestó a la obra literaria y no literaria de José María Arguedas. En este trabajo pretendemos establecer la relevancia del acercamiento de Altuna con la obra arguediana para ejemplificar cómo este caso, metonímicamente, expresa la realidad de una flujo intelectual y artístico entre las áreas culturales sudatlántica y andina. Bajo el lente de algunas de las categorías críticas de Altuna, releeremos la polémica Arguedas/Cortázar de los años sesenta para, desde esa reflexión, situar el trabajo crítico de Elena Altuna, atendiendo a una ponencia que leyó la autora sobre Arguedas en 2011.
Melancolía y espectralidad en Boca de lobo de Sergio Chejfec
Authors: Guerra Juan José
Published: December 2022

Este trabajo analiza Boca de lobo (2000) de Sergio Chejfec partiendo de la hipótesis de que en el texto se construye un futuro conjetural que tiene la forma de un porvenir brumoso y abrumador. Correlativamente, que el suburbio industrial se diseña más sobre la huella de tradiciones conceptuales y estéticas que sobre una base empírica o referencial, y en ese sentido el espacio urbano está construido por medio de mecanismos de desfiguración y desvanecimiento que tienden a esfumar lo real. La novela propone una indagación sobre el efecto que los restos del pasado producen en el presente. El trabajo interpreta esos restos en una triple dimensión: subjetiva, en la medida en que se refieren a un vínculo amoroso y las secuelas tras la ruptura; histórica, porque aluden al mundo del trabajo industrial en su punto de desintegración; y literaria, en tanto dejan oír resonancias de diversas tradiciones culturales que van del realismo social y el marxismo a la literatura gauchesca. Las tres dimensiones están imbricadas por los conceptos de “melancolía” (Freud, Butler) y “espectralidad” (Derrida), dado que expresan, respectivamente, la imposibilidad de dar por perdido el objeto y la persistencia fantasmática del pasado.
La reinterpretación del genio romántico en Nadja de André Breton
Authors: Mazón Ontiveros Rafael
Published: December 2022

En el presente artículo se realiza un análisis de la novela Nadja, obra maestra del surrealismo literario,  del escritor francés André Breton. Contrario a las aportaciones científicas realizadas por el campo del psicoanálisis, este texto busca estudiar el texto a partir del concepto del genio, noción fundamental para la estética romántica (con la cual el surrealismo guarda hondas semejanzas), con el afán de realizar una novedosa aportación al campo de los estudios literarios, y la relación de estos con la filosofía. El trabajo estará dividido en tres partes claramente diferenciadas: una introducción, en la cual se hablará concisamente sobre la figura de André Breton, así como de algunos presupuestos del surrealismo; luego, se describirá el concepto de genio romántico a partir de algunas investigaciones actuales; finalmente, se intentará estructurar una interpretación pertinente de la novela usando la noción de genialidad romántica para estudiar la relación entre el personaje de Nadja y el narrador.
Lenguaje no binario en las aulas: lo disruptivo de la emergencia social frente al poder de la norma
Authors: Bórtoli Pamela V.
Published: December 2022

Desde hace algunos años, Argentina es uno de los focos de la aparición, en escenarios diversos, de ciertos usos lingüísticos cobijados bajo el nombre de “lenguaje inclusivo”. Este artículo se centra en el campo de los estudios superiores, en tanto se reconoce su circulación y el numeroso grupo de universidades nacionales que aprobaron su uso a través de resoluciones del Consejo Superior y el Consejo Directivo. Se parte de la hipótesis de que es un desafío de las universidades nacionales diagramar una gramática descriptiva que oriente a quienes deseen usar el lenguaje inclusivo/no sexista y se avanza en una sistematización que reconoce tres posturas diferentes: por un lado, una «línea de lenguaje androcéntrico», apoyada por quienes sostienen la existencia de una lengua pura y se aferran a la norma; por otro, una «línea de lenguaje binario», conformada por quienes intentan visibilizar a las mujeres; por último, una «línea de lenguaje no binario», que agrupa los usos que consideran a todas las personas no subsumidas en la dicotomía masculino/femenino. Se ofrece una propuesta didáctica que permite abordar esta problemática y pone a disposición herramientas para decidir -o no- utilizar un lenguaje no sexista o inclusivo.
Research on Autopilot Trajectory Planning Based on Deep Learning
Authors: Ren Qiong , Chang Junming
Published: December 2022

Vehicle trajectory is usually used in driving behavior modeling and traffic safety. In order to obtain vehicle tracks in traffic video, an automatic acquisition method based on depth learning is proposed. In this paper, the YOLOV5 detector is used to detect vehicles in the region of interest in continuous frames, and the DEEPSORT tracker is used to track robust and fast vehicles. This tracker can effectively reduce the jump of target ID, improve tracking stability, obtain the real-world coordinates of vehicles through perspective transformation, and use a locally weighted regression algorithm to smooth the track. The experimental results show that the average multi-target tracking accuracy of the method in the expressway monitoring data set is 96.1%, and the average accuracy of trajectory acquisition is more than 93%. The smoothing algorithm can effectively remove the trajectory noise.

Abnormal pressure in the annulus is one of the main risks that threaten the safe production of gas wells and affect their production efficiency. To further improve the gas well annulus pressure management level based on the gray system theory and new information priority ideology, this study introduced a new perspective. First, we considered the influence of various factors related to the change of the gas well annulus pressure and performed a grey correlation analysis. Next, we established a multivariable grey prediction model of gas well annular pressure with the associated metabolic function. The measured data of high-pressure and high-yield gas wells in Northwestern Sichuan for 12 consecutive hours in a day, was used as a case study. The effectiveness of this proposed model was verified by comparing the predicted results with the measured data. The research results verify the feasibility of the gray system theory for the dynamic prediction of gas well annulus pressure and provide theoretical support for the early diagnosis and active prevention of continuous annulus pressure.

Rapid and Safe Arc Quench by Using External Magnetic Coil in Power Interruption
Authors: Wang Qian , Liang Fangwei , Zhou Xinmiao
Published: December 2022

Low-voltage arc quench is one of the most processes for a successful power interruption in circuit breakers. Typical circuit breakers are designed to switch off the fault current within half a cycle, less than 10 milliseconds, which requires an efficient arc quench and thus poses great challenges in power interruption. Apart from using power electronics, which is very expensive and of low capacity, the classical circuit breakers that uses a stack of steel plates to split the fault-current arc into many sub-arcs are still dominant for both industry and residential installations. Due to the high current, the self-induced magnetic field will drive the arc towards to the steel plates and force the arc being spitted into many sub-arcs, from which the arc-steel plate interfaces generates multiple voltage drops. Once the sum of all voltage drops increases and exceeds the source voltage, the arc will extinguish and quench.  Due to the ferromagnetic effect, the magnetic field increases dramatically during arc splitting by steel plates. However, the self-induced magnetic field have reversed direction on both sides of the steel plates which pushes the sub-arcs to opposite directions and prevents concurrent and even arc splitting. In this report, we report a new technique to compensate the self-induced the magnetic field by using a background magnetic coil, thus, to give an even and simultaneous arc splitting and guarantee the power interruption.
