Does a family-first philosophy affect family business profitability? An analysis of family businesses in the midwest

Previous family business literature has analyzed how various management strategies or family tension has impacted profit. However, profit can vary due to the different family values and goals placed on the firm. The purpose of this study was to investigate how the business philosophy of a family business influenced profit. The present study sought to examine how the family business\u27 philosophy, as in if they have a family-first or business-first orientation, influences profit. This study also investigates how the distribution of the business to the next generation, as well as how hiring family members who may not have the qualifications to key management positions, could decrease family business profit. Results showed that a family-first philosophy did not have a statistically significant effect on profit, while distributing the business to a family successor positively affected profit. The attitude that family members should be hired to a key management position regardless of their qualification did not significantly affect business profit. A firm\u27s transfer plan positively impacted business profit

Ionic Liquids as High-Performance Lubricants and Lubricant Additives

Taking into account the environmental awareness and ever-growing restrictive regulations over contamination, the study of new lubricants or lubricant additives with high performance and low toxicity over the traditional lubes to reduce the negative impact on the environment is needed. In this chapter, the current literature on the use of ionic liquids, particularly protic ionic liquids, as high-performance lubricants and lubricant additives to different types of base lubricants are reviewed and described. The relation between ionic liquids structures and their physicochemical properties, such as viscosity, thermal stability, corrosion behavior, biodegradability, and toxicity, is elaborated. Friction reduction and wear protection mechanisms of the ionic liquids are discussed with relation to their molecular structures and physicochemical properties

Is it possible to apply inquiry in the first level of primary school without hindering the acquisition of scientific competencies? Perspectives of pupils and their pre-service teacher

Producción CientíficaThe aim of this study is to assess the application of inquiry as a teaching strategy during the practicum of a pre-service teacher and to verify the acquisition of scientific skills by her students. The importance of this study is the application of inquiry as a teaching strategy at lower levels of basic education to contribute to scientific skills and scientific literacy. The sample consisted of 27 pupils in the first level of primary education and one pre-service teacher in a Spanish school. The methodology used was a case study with a participatory experimental design, incorporating guided discovery and teacher questioning focused on plant growth. The results indicate that the pupils improved their understanding and assimilation of content related to plant functions, scientific procedures, and critical thinking. The pre-service teacher demonstrated mastery of the inquiry-based methodology, confirming an adequate level of both pedagogical and scientific competence. Some suggestions are provided to enhance her training. The study concludes by demonstrating that it is possible to implement inquiry at any educational level, despite the potential limitations of the students. It is recommended that pre-service teachers receive comprehensive training to enable them to facilitate the acquisition of scientific competence among their students.Ministerio de Economía y Competitividad - (project EDU2017-89405- R

Definición de XML schemas para la prescripción de fórmulas magistrales en dermatología

Este trabajo plantea la elaboración de una herramienta que facilitará la creación de las fórmulas magistrales más comunes del ámbito de la dermatología. Para el desarrollo de dicha herramienta se contó con la colaboración de una dermátologa que proporcionó la información de las diversas patologías (psoriasis, alopecia, mucosa, dermatitis y rosacea) cuyos modelos de datos se elaboraron. El diseño de esta herramienta se basó en la creación de una novedosa arquitectura extensible y modular, que permite incluir una nueva patología para modelar con XML Schema, sin necesidad de rediseñar la herramienta como ocurre con las ya existentes. Además de la introducción de restricciones a través de un lenguaje potente, a la vez que novedoso, como es el lenguaje Schematron, que facilitan el control de las incompatibilidades de los principios activos entre sí. Todo ello sin olvidar la parte visual, creando un hoja de estilos en XSLT que permite definir el documento pdf final, que resume gráficamente todo el trabajo realizado, además de mostrar un formato adecuado para la presentación de la fórmula magistral completa

Influence of sliding frequency on reciprocating wear of mold steel with different microstructures. Poster

Large forged steel blooms are employed to fabricate molds for plastics used in the automotive industry. Each mold is expected to produce a few millions of pieces in its life. Wear under service conditions may be severe and may combine with other stresses to cause crack nucleation and failure. The present manufacturing process consists of machining pre-hardened blooms. The dimensions of the blooms use to exceed the hardenability of the steel, thus different microstructures occur at increasing depths, all of them being affected by the subsequent tempering. Due to finishing operations, any of the microstructures occurring at different positions in the original bloom can be found at the mold face. Thus, steel properties and wear resistance should be studied as a function of the microstructure.We thank MEC (Spain), EU FEDER (MAT2005-00067, MAT2008-01670) for financial support

Assessment the SlidingWear Behavior of Laser Microtexturing Ti6Al4V under Wet Conditions

Laser micro-texturing processes, compared to untreated surfaces, can improve the friction, wear and wettability behavior of sliding parts. This improvement is related to the micro-geometry and the dimensions of the texture which is also dependent on the processing parameters. This research studied the effect of laser textured surfaces on the tribological behavior of titanium alloy Ti6Al4V. The influence of processing parameters was analyzed by changing the scanning speed of the beam and the energy density of pulse. First, the characterization of dimensional and geometrical features of the texturized tracks was carried out. Later, their influence on the wetting behavior was also evaluated through contact angle measurements using water as a contact fluid. Then, the tribological performance of these surfaces was analyzed using a ball-on-flat reciprocating tribometer under wet and dry conditions. Finally, wear mechanisms were identified employing electronic and optical microscopy techniques capable to evaluate the wear tracks on Ti surfaces and WC–Co spheres. These analyses had determined a strong dependence between the wear behavior and the laser patterning parameters. Wear friction effects were reduced by up to a 70% replacing conventional untreated surfaces of Ti6Al4V alloy with laser textured surfaces

New α-keto acid-derived hydrazone ligands and their reaction with the {Re(CO)3}+

Two hydrazone ligands derived of phenylglyoxylic acid (HL1) and 4-hydroxyphenylpyruvic acid (HL2) were synthesized and their zwitterionic structures were determined by X-ray diffraction. The rhenium(I) complexes of formula [ReCl(HLn)(CO)3] were obtained by reaction of the ligands with [ReCl(CH3CN)2(CO)3]. The formation of the hydazonate complexes were also achieved. In the case of HL1 the trimetic complex [Re3(L1)3(CO)9] was isolated by using a basic medium. On the other hand, from storage of a solution of the [ReCl(HL2)(CO)3] complex, crystals of the [Re2(L2)2(CO)6] dimer could be obtained for their structural analysis by X-ray diffraction. The study of the crystalline structures is included. The coordination geometry around rhenium(I) can be described as octahedral with three carbon atoms in fac configuration. In all complexes a five-membered chelate ring is formed including two nitrogen atoms from the hydrazone chain and the pyridine group. In the mononuclear complexes the carboxylic group does not participates in the coordination but acts as a bridge to form the polynuclear compounds. The coordination mode of the ligands in all the complexes could be corroborated by comparative studies of the experimental and calculated (DFT) IR spectra.Agencia Estatal de Investigación | Ref.
