La tecnología: un aliado en el aula
Authors: Pérez Torres Mónica Lorena , Hernández Arteaga Isabel 
Published: July 2018

Este artículo de reflexión es el resultado de una investigación que permitió evidenciar las implicaciones de las tecnologías de la información y la comunicación (TIC) en la educación superior, particularmente en el proceso de formación profesional. Se demuestra la necesidad de que instituciones, docentes y estudiantes cambien el paradigma frente a su uso pedagógico, permitiendo que las TIC se conviertan en aliadas ―y excusa perfecta― que orienten el proceso de enseñanza-aprendizaje, para que los futuros profesionales estén en capacidad de participar efectivamente en la sociedad del conocimiento. De otra parte,
se reconoce que su uso pedagógico posibilita al estudiante aprender mediante múltiples metodologías y desde diversos escenarios, geográficos y temporales, que facilitan el logro
de las competencias profesionales que la sociedad y el mundo laboral demandan. Esta reflexión conlleva reconocer que el uso de las TIC en la formación profesional demanda la generación e innovación de estrategias didácticas que rompan las barreras espaciotemporales, exigiendo a los actores educativos una actualización crítica y permanente sobre la utilización de programas y dispositivos electrónicos como herramientas que
apoyan el proceso de aprendizaje significativo.
Investor Relations and Information Assimilation
Authors: Chapman Kimball , Miller Gregory S. , White Hal D. 
Published: July 2018

ABSTRACT
This paper examines whether investor relations (IR) officers provide value by facilitating the assimilation of firm information by the market. We find that firms with IR officers have lower stock price volatility, lower analyst forecast dispersion, higher analyst forecast accuracy, and quicker price discovery, consistent with IR officers aiding market participants in their assimilation of firm information. We also show that our findings are stronger for firms with longer-tenured IR officers. Finally, we find that when firms transition from a long-tenured IR officer to a new IR officer, stock price volatility increases, analyst forecasts become more disperse and less accurate, and the price discovery process slows, despite no significant change in the firm's disclosures, media coverage, or performance around the turnover. Collectively, these findings suggest that in-house IR officers, particularly those with greater experience, help facilitate information assimilation by the market, which has positive market effects.

Executive Extraversion: Career and Firm Outcomes
Authors: Green T. Clifton , Jame Russell , Lock Brandon 
Published: July 2018

ABSTRACT
Psychology research identifies extraversion as the personality trait most closely associated with leadership emergence. We examine executive extraversion, as measured by speech patterns during conference calls, and find extraverts experience significant career benefits. Controlling for executive and firm characteristics, including firm fixed effects, we find that extraverted CEOs and CFOs earn 6–9 percent higher salaries. Moreover, extraverted CEOs are less likely to experience job turnover, have longer tenures, serve on more outside boards, and hold directorships at larger firms, and extraverted CFOs are more likely to be promoted to CEO. Executive extraversion is also linked with firm outcomes. Analyzing a sample of manager transitions, we find that increases in CEO extraversion are associated with improvements in investor recognition and sales growth. Further, extraverted CEOs are associated with higher acquisition announcement returns. Our findings highlight the role of personality traits in explaining executive career and firm outcomes.

Effectiveness of the Tooth Zone of Inductor Electric Machine
Authors: Serebryakov A. , Kamolins E. , Gulbis K. , Sejejs K. 
Published: July 2018

Abstract
The authors consider several tens of rotor tooth and slot profiles for the inductor electric machine in order to gain the maximum EMF of the armature winding at the minimum of highest harmonics, owing to which the specific power and efficiency of the machine can be raised.
The research considers usage of analytical methodology and finite element method (FEM), where the latter includes magnetic saturation and actual magnetic field line distribution.
The main data of both calculations are summarised in the results of the study. From the obtained results, it can be concluded that, in most cases, the analytical method is not applicable to the qualitative determination of the highest harmonic content of the EMF, since the plane of the magnetic field lines does not close in parallel and their distribution is directly related to the configuration of the teeth zone.
The possibility of using the inductor generators for direct connection to the grid is demonstrated in the study.

Abstract
Peculiarities of metals uptake by the biofuel crop Miscanthus x giganteus were explored during plant growth at soil from the military site (Sliač, Slovakia). The experiment was carried out in greenhouse during two vegetation seasons. Research soil was predominantly elevated in Fe and Ti, while other metals (As, Cu, Mn, Sr, Zn and Zr) were presented at order of magnitude lower concentrations. No inhibition of plant growth was observed. The calculated Bioconcentration Factor showed that levels of metals’ accumulation by plant roots, stems and leaves were independent of metals’ concentrations in the soil. The accumulation of metals by stems and leaves was much lower than by roots. As, Zr, Ti were almost not accumulated by stems and leaves during both seasons; accumulation of Cu, Fe, Mn, Zn and Sr was not essential which confirmed that biomass of M. x giganteus might be processed for the energy purpose.
Synthesis of a novel environmental friendly plasticizer based on tung oil fatty acid for poly (vinyl chloride) blends
Authors: Tong Hanqing , Hai Jinping 
Published: July 2018

Abstract
A novel environmental friendly plasticizer (TPE) derived from tung oil fatty acid with long fatty acid chain and high degree of branching was synthesized. Chemical structure of the obtained TPE was characterized with Fourier transform infrared spectroscopy (FT-IR) and 1H NMR. TPE was used to prepare plasticized PVC blends as main plasticizer. Thermal stability, mechanical properties and migration resistance of poly (vinyl chloride) plasticized with TPE were investigated. The results showed that torque data of plasticized PVC blends reached 12.4 N·m when the mass of the TPE was 50 wt.%. TPE improved the thermal stability of PVC blends obviously than dioctyl phthalate (DOP). The leaching tests showed that PVC plasticized with TPE were with higher migration resistance than that of DOP. The excellent thermal stability and high migration resistance of PVC blends showed high application value for TPE.
Experiment and prediction of water content of sour natural gas with an modified cubic plus association equation of state
Authors: Liu Yang , Zhu Yun , Zhu Jun 
Published: July 2018

Abstract
In this work, new experimental value for water content in sour natural gas were reported. In addition, to predict the water content in sour natural gas, a modified cubic plus association equation of state (CPA-EoS) was also proposed. In this model, a new energy parameter a was proposed to make an accurate description of saturated liquid density. Additionally, a temperature dependent binary interaction parameter kij for six binary systems was also obtained. Lastly, a comparison between the prediction results of the modified CPA-EoS and the experimental data was presented, and the results showed that the modified CPA-EoS could predict the water content in sour natural gas with high accuracy, which has an AAD of 3.6722% with experimental data in literatures and an AAD of 1.946% for experimental data reported in this work.
Stress–Dilatancy For Crushed Latite Basalt
Authors: Dołżyk-Szypcio Katarzyna 
Published: July 2018

Abstract
In this article, the stress–dilatancy relationship for crushed latite basalt is analysed by using Frictional State Theory. The relationship is bilinear, and the parameters α and β determine these two straight lines. At the initial stage of shearing, the mean normal stress increment mainly influences breakage, but at the advanced stage, it is shear deformation that influences breakage. At the advanced stage of shearing, the parameter αpt
represents energy consumption because of breakage and βpt
mainly represents changes in volume caused by breakage during shear. It is also shown that breakage effect is significant at small stress levels and the η-Dp
plane is important to fully understand the stress–strain behaviour of crushed latite basalt in triaxial compression tests.
Concrete surface evaluation based on the reflected TLS laser beam’s intensity image classification
Authors: Zaczek-Peplinska Janina , Osińska-Skotak Katarzyna 
Published: July 2018

Abstract
Dynamically developing terrestrial laser scanning technology (TLS)provides modern surveying tools, that is, scanning total stations and laser scanners. Owing to these instruments, periodic control surveys of concrete dams were performed as a part of geodetic monitoring yield point models characterised by quasicontinuity. Using the results of such measurements as a base, one can carry out a number of geometric analyses as well as acquire information for detailed analytical and calculative considerations.
The scanner, similar to total station, by determining distances and angles, identifies spatial coordinates (X, Y, Z) of the surveyed points. Registration of the reflected laser beam’s intensity value (Intensity) emitted by the scanner provides additional information on the surveyed object. Owing to high working speed and the large amount of the collected data, the scanners became an indispensable tool for geodesists.
The article assesses the possibility of application of terrestrial laser scanning in surveying changes in the surface of a concrete dam based on the experimental measurements. The condition of the dam’s downstream concrete wall was evaluated. The evaluation included changes in the surface’s roughness, cracks, seepage points, erosion caused by plant overgrowth and the degressive durability parameter of the used material (concrete).
The article presents an example of the application of the results of a laser scan in the assessment of the condition of a water dam’s external concrete surfaces. The results of experimental measurements were analysed – the results of a scan of the downstream concrete wall of a dam in Ecker (Germany) using two laser scanners characterised by different technical parameters, that is, laser wavelength (laser’s colour), range, definable point density, method of distance measurement – Leica C10, Z+F Imager 5006h. The measurement was carried out in the same weather conditions from the same sites of the test base.
The results of the measurements were analysed using, inter alia, statistical methods by defining template fields and supervised and unsupervised classification methods in reference to the selected fragments of the surface characterised by known concrete surface properties. Various classification algorithms were used. The obtained results make it possible to assess the suitability of the proposed methodology of evaluating the concrete surface’s condition and establish tool selection principles to match the practical application requirements.

Abstract
Abundance and distribution of nematodes of the genus Trichuris Schrank, 1788 parasitizing domestic sheep (Ovis aries Linnaeus, 1758) were studied in Poltava, Kyiv and Zaporizhzhia Regions of Ukraine. Three species of Trichuris were found, Trichuris skrjabini Baskakov, 1924, Trichuris ovis Abildgaard, 1795 and Trichuris globulosa Linstow, 1901. Trichuris ovis and T. skrjabini were more common (54.9 and 35.7 %), whereas T. globulosa was relatively rare (9.4 %) in the studied material. New species-specific and sex-related morphological characters and metric indices were reviewed as useful in better identification of T. skrjabini, T. ovis and T. globulosa parasitizing sheep.

Communication Strategies Used in Corporate Facebook Pages and Motivations of Consumers for Following These Pages
Authors: Emeksiz Gülçin İpek , Şimşek Ali 
Published: July 2018

Abstract
The new communication tool of our current era is certainly Facebook because it is the most commonly used social network application in the world. Therefore, consumers perceive businesses which are not a member of Facebook as a business which cannot keep up with the new era and thus they want their favourite brands to be on Facebook. However, for businesses to be on Facebook is not just about opening a profile page. Businesses need to create a brand community that they get into interaction with their stakeholders in order to gain dynamism and mobility to their Facebook brand fan pages. Therefore, businesses need a variety of effective corporate communication strategies that they can apply on their Facebook pages. The corporate communication strategy that a business employs on Facebook should be compatible with the goals and purposes that a business wants to reach. A business which use a certain corporate communication strategy on Facebook will determine the contents that it will share on Facebook in line with this strategy and will create the desired perception on its target audience. On the other hand, a business which doesn’t apply a particular corporate communication strategy on Facebook probably doesn’t know which goals that it wants to reach. Therefore, businesses which share random contents on their Facebook pages try to continue their Facebook pages by trial and error. However, because of this situation, they cannot get the desired effectiveness, appeal and efficiency from their Facebook pages in the long term. Furthermore, stakeholders need some level of motivation in order to follow businesses on Facebook. If a business knows what the motives of usage are, it can shape its Facebook messages in the right direction. This way, more followers will gather around the brand community of the business on Facebook.

Kader kesehatan merupakan ujung tombak pelaksanaan Posyandu di masyarakat. Kader kesehatan mempunyai tugas untuk mengelola pelaksanaan Posyandu, mulai dari persiapan, pelaksanaan dan pasca pelaksanaan Posyandu di setiap bulan. Banyak Posyandu yang mati suri atau keberadaannya ada tetapi tidak berfungsi sebagaimana yang diharapkan. Hal ini dapat dilihat dari strata Posyandu yang kebanyakan masih ada dalam strata Madya dan Purnama. Keberadaan kader kesehatan memegang peran utama dalam pelaksanaan Posyandu. Tetapi yang menjadi kendala adalah kinerja kader Posyandu yang dianggap masih kurang dan banyak kader yang memutuskan berhenti menjadi kader. Tujuan penelitian ini adalah untuk mengetahui kinerja kader dalam pelaksanaan Posyandu di Kabupaten Kudus. Metode penelitian menggunakan penelitian kualitatif dengan pendekatan fenomenologi. Jumlah informan ada 11 orang kader . Pengambilan data dilakukan secara wawancara mendalam menggunakan panduan wawancara dengan pertanyaan bersifat terbuka. Triangulasi dilakukan dengan melakukan wawancara dengan Bidan Desa.Penelitian dilaksanakan pada bulan Maret-April 2018 di wilayah Kabupaten Kudus. Hasil penelitian didapatkan bahwa kader kesehatan sudah mengetahui tugas dan tanggungjawabnya sebagai kader kesehatan. Pemberian insentif bagi kader dianggap dapat meningkatkan motivasi kader dalam menjalankan tugas. Pengakuan resmi dari pemerintah atau desa dianggap sebagai suatu bentuk penghargaan bagi kader. Kelengkapan sarana prasarana serta dukungan dari pemerintah desa sangat membantu pelaksanaan tugas kader. Perlu adanya pelatihan bagi kader untuk meningkatkan kompetensi kader terutama bagi kader kesehatan baru.
