Authors: Soto Arango Diana Elvira , Rivadeneira Vargas José Antonio , Duarte Acero Jorge Enrique , Bernal Villate Sandra Liliana
Published: July 2018

El objeto de este trabajo se enfoca en analizar dos líderes estudiantiles, que vivieron el periodo del centenario de la independencia americana, pero a su vez les correspondió la época del movimiento estudiantil colombiano y la incidencia del de Córdoba en esta región latinoamericana. Nos referimos a Luis López de Mesa, (1884-1967) generación del centenario, y Germán Arciniegas (1900-1999) generación de los nuevos.  El periodo histórico se toma de 1910 a 1924 que corresponde a primer y segundo Congreso estudiantil colombiano. Desde la historia política, se analizará a estos dos líderes estudiantiles que luego ocuparon el ministerio de educación, bajo gobiernos liberales. Se caracterizaron por la docencia universitaria, aportes en el periodismo y nuevos planteamientos de reforma hacia la universidad colombiana. Son dos figuras que se estudiaran desde la concepción que tenían sobre la educación, la universidad y sus propuestas universitarias desde la mirada de los movimientos estudiantiles y en especial lo que llegó del Movimiento de Córdoba a Colombia. La metodología se establece desde la comparada sustentada principalmente en fuentes primarias.
La transformación del paisaje de Santa Fe de Antioquia: reconfiguración del centro histórico y su entorno natural
Authors: Escobar Ocampo Lina María , Montoya Arenas Catalina , Patiño Zuluaga Evelyn , González Escobar Luis Fernando
Published: July 2018

Los cambios y transformaciones recientes del paisaje del centro histórico y bordes urbanos en Santa Fe de Antioquia han sido procesos acelerados que dejan a su paso el deterioro y pérdida del patrimonio natural y cultural que brinda identidad al lugar. Dichos efectos son producidos, entre otros factores, por la incidencia del marketing turístico y patrimonial que reconfiguran el tejido socio espacial y el entorno natural. A través de la delimitación y análisis de unidades de paisaje en el denominado paisaje cotidiano y la caracterización del paisaje natural se pudo establecer la estrecha relación entre la pérdida de cobertura vegetal, uso del suelo y la subdivisión predial como indicadores de los cambios en el modelo de ocupación, identificando impactos ambientales y antrópicos en el Bosque Seco Tropical y la incidencia que dichos cambios culturales están imprimiendo en la actualidad a la relación dialógica entre el centro histórico y su entorno natural. La relevancia de esta reflexión se enmarca en la interpretación de las dinámicas históricas recientes en simultáneo con información cualitativa y cuantitativa, para el análisis del paisaje como recurso patrimonial en una planificación territorial más equilibrada, que incluya la revisión de transversalidades paisajísticas.

Published: July 2018

El objetivo principal es analizar económicamente el sector cacaotero en Norte de Santander, Colombia y a nivel internacional. El método es deductivo con estudio descriptivo y de campo. Se consultaron fuentes como instituciones del cacao en Colombia y a nivel internacional, así como fuentes documentales de organismos estatales y privados. En cuanto a resultados y conclusiones se tiene que en Norte de Santander, así  como en Colombia, se requiere aumentar la producción de cacao y su tecnificación en el cultivo para aprovechar la alta demanda internacional de cacao y sus derivados, así como los buenos precios para ampliar su participación internacional, tomando la ventaja diferencial del cacao fino y de aroma. Lo anterior debe ir acompañado de la generación de valor agregado, competitividad, aprovechamiento de los tratados comerciales vigentes en Colombia y la proyección del cacao como cultivo clave del postconflicto colombiano.
Análisis de contenido del concepto de área en educación superior
Authors: Villamil-Rincón Diana Lucía , Aldana-Bermúdez Eliécer , Wagner-Osorio Graciela
Published: July 2018

En este artículo se propone una tarea que ayude en la construcción del concepto de área, en estudiantes de primer semestre de tecnología en topografía de la Universidad del Quindío. El diseño didáctico se realizó con base en el análisis de contenido del concepto de área a nivel universitario, tomando en cuenta los siguientes organizadores del currículo: La estructura conceptual, los sistemas de representación y la fenomenología. Se analizó una tarea de diagnóstico en la cual los estudiantes deben realizar el diseño de la figura para ubicar un jardín en un centro comercial. El área en la solución de la tarea no se expresa mediante un valor numérico ni con unidades de medida; el propósito es establecer una comparación del área de dos superficies cuadradas por medio de la razón entre ellas. Los resultados indican que se diseñó una tarea significativa para los estudiantes, ya que es una situación problema del concepto de área en el contexto topográfico. Los estudiantes deben emplear los conocimientos previos y la tarea representa un desafío al resolverla, ya que la falta de medidas en la representación gráfica obligan al estudiante a desarrollar un nivel de abstracción más complejo que la simple aplicación de un algoritmo.

El cincuentenario de la «transposición con el saco herniario» de Lázaro da Silva para reconstrucción de la pared abdominal ventral
Authors: De Melo Renato Miranda
Published: July 2018

En 1968, en el interior de Brasil o, más específi camente, en Belo Horizonte, capital del estado de Minas Gerais, frente a las difi cultades de acceso a las raras y costosas mallas de polipropileno, nacía una propuesta para corregir las hernias incisionales medianas, fundamentada en incisiones de descarga en las vainas de los músculos rectos del abdomen y en la utilización del propio saco herniario. En este momento el procedimiento era hecho por Alcino Lázaro da Silva, un cirujano general contumaz y entonces profesor de la Facultad de Medicina local, que no se conformaba con descartar el saco herniario, en su opinión una estructura vital y resistente, que podría ser útil en la corrección de aquellas hernias. En los años anteriores, fue divisando la técnica que denomino «transposición peritoneo-aponeurótica longitudinal bilateral» o, más brevemente, «transposición con el saco herniario» (TSH), su mayor diferencial. Aquí se relata la historia que lo llevó a elaborar su propuesta, la descripciónn textual e iconográfi ca del procedimiento y sus principios orientadores, además del razonamiento que fundamenta los resultados favorables obtenidos con la adopción de la técnica. En este año de 2018, se conmemora el cincuentenario de la TSH, una de las alternativas que el cirujano general podrá disponer, para la reconstrucción de la pared ventral del abdomen, sin el uso de prótesis sintéticas.

Se inicia con un período anatómico, luego quirúrgico, continuándose con otro protésico y terminando actualmente con un período miniinvasivo, laparoscópico y robótico. Argentina ha contribuido tempranamente desde el período quirúrgico.
La variación en las abreviaturas: cómo expresar el género y el número
Authors: Latorre Lidia
Published: July 2018

Las abreviaturas en los textos científicos agilizan la lectura del texto, pero no debe abusarse de ellas para asegurar siempre la comprensión del lector. Existen dos procesos de formación principales3: contracción y truncamiento. En las abreviaturas por contracción se eliminan algunas letras centrales y se dejan las más representativas. Es el caso de n.º por número o Sr. por señor. En cambio, en las abreviaturas por truncamiento se suprimen las letras o sílabas finales, como ocurre en Dir. por director o pág. por página. En algunas ocasiones únicamente conservamos la letra inicial, se trata de truncamientos extremos y es lo que ocurre en EE. UU. por Estados Unidos o en los nombres propios de los autores en nuestras citas bibliográficas.

The Women Characters in Joseph Conrad’s Heart of Darkness
Authors: Gadekar Sachin
Published: July 2018

The present research paper is an attempt to provide a comprehensive account of the female characters in Joseph Conrad’s well-known novella Heart of Darkness. The real interest of this study lies in what Conrad has to say about female characters, conduct and also the way in which he projects them.

Thus, I have here attempted to examine the female characters in Conrad’s Heart of Darkness, to set these characters against their male counterparts, and so, to allow an increased awareness of the depiction of female characters as submissive, dominated by men, often deceived by others and with lack of their own identity. Clearly, it would be little short of a marathon task to do the study of all Conrad’s major fictions with feministic perspective, and so, this study limits its concern to his masterpiece novella such as Heart of Darkness
Rehabilitation for Children With Dystonic Cerebral Palsy Using Haptic Feedback in Virtual Reality: Protocol for a Randomized Controlled Trial (Preprint)
Authors: McNish Reika Nicole , Chembrammel Pramod , Speidel Nathaniel Christopher , Lin Julian Jwchun , López-Ortiz Citlali
Published: July 2018

BACKGROUND

Cerebral palsy (CP) is the most common developmental motor disorder in children. Individuals with CP demonstrate abnormal muscle tone and motor control. Within the population of children with CP, between 4% and 17% present dystonic symptoms that may manifest as large errors in movement tasks, high variability in movement trajectories, and undesired movements at rest. These symptoms of dystonia typically worsen with physical intervention exercises.

OBJECTIVE

The aim of this study is to establish the effect of haptic feedback in a virtual reality (VR) game intervention on movement outcomes of children with dystonic CP.

METHODS

The protocol describes a randomized controlled trial that uses a VR game-based intervention incorporating fully automated robotic haptic feedback. The study consists of face-to-face assessments of movement before, after, and 1 month following the completion of the 6-session game-based intervention. Children with dystonic CP, aged between 7 and 17 years, will be recruited for this study through posted fliers and laboratory websites along with a group of typically developing (TD) children in the same age range. We anticipate to recruit a total of 68 participants, 34 each with CP and TD. Both groups of children will be randomly allocated into an intervention or control group using a blocked randomization method. The primary outcome measure will be the smoothness index of the interaction force with the robot and of the accelerometry signals of sensors placed on the upper limb segments. Secondary outcomes include a battery of clinical tests and a quantitative measure of spasticity. Assessors administering clinical measures will be blinded. All sessions will be administered on-site by research personnel.

RESULTS

The trial has not started and is pending local institutional review board approval.

CONCLUSIONS

Movement outcomes will be examined for changes in muscle activation and clinical measures in children with dystonic CP and TD children. Paired t tests will be conducted on movement outcomes for both groups of children independently. Positive and negative results will be reported and addressed.

Published: July 2018

Este trabajo aborda las vivencias de mujeres estudiantes universitarias indígenas que se autodefinen como pertenecientes a diferentes etnias del estado de Chiapas, México. Desde una perspectiva hermenéutica, se analiza la información recolectada a través de entrevistas, a partir de lo cual se da cuenta de las formas en que los mecanismos estructurales de la sociedad, caracterizada por una cultura patriarcal y sostenida por un sistema económico capitalista neoliberal, definen sus experiencias como mujeres estudiantes indígenas. Los hallazgos constituyen una forma de denuncia de las violencias sistemáticas vigentes en contra del género femenino indígena, y muestran la capacidad de resistencia de las estudiantes a través de la formación académica, el anclaje a la identidad de ser mujer e indígena y del cuestionamiento ante la subordinación de otras mujeres, que les permite soportar las opresiones de la sociedad y la cultura de las que son víctimas, así como dibujarse un futuro alternativo y mejor
Canine Babesiosis: Where Do We Stand?
Authors: Petra Bilić , Josipa Kuleš , Renata Barić Rafaj , Vladimir Mrljak
Published: July 2018

Canine babesiosis is a tick-borne disease caused by protozoal haemoparasites of different Babesia species. Babesiosis is one of the most important globally extended and quickly spreading tick-borne infections of dogs. This comprehensive review gives an in-depth overview of Babesia species currently identified in dogs together with relevant vector tick species and their geographical distribution, life cycle and transmission of parasite. The main mechanisms in the pathogenesis of babesiosis are described and elucidated by recent literature overview. As Babesia infection causes a disease with very variable clinical manifestations, special attention is given to clinical signs, laboratory features and clinicopathological findings. The diagnosis of canine babesiosis by microscopy, serological and molecular methods is reviewed, together with recent advances in mass spectrometry based assays. Accurate detection and species recognition are important for the selection of the appropriate therapy, monitoring and prediction of the outcome of the disease. Finally, guidelines for the treatment and prevention of canine babesiosis are given.
MAC-Sparing Effect of Transdermal Fentanyl in Sevoflurane-Anesthetized Sheep
Authors: Lauren Duffee , Eraldo Passino Sanna , Antonio Scanu , Nicolò Columbano
Published: July 2018

Transdermal fentanyl allows for consistent plasma concentrations of a potent synthetic μ-opioid receptor agonist and can provide constant post-operative analgesia for up to 72 h. The aim of this study was to determine the reduction of the minimum alveolar concentration of sevoflurane (MACSEVO) by transdermal fentanyl in nonpregnant ewes. Nine sheep were mask induced with sevoflurane (SEVO in oxygen). MACSEVO determinations involved electrical current applied to the lateral metacarpus as a supramaximal stimulus and measurements in duplicate. Seven days later, a fentanyl patch (75 μg/h) was applied to each sheep and 15.1 ± 1.8 h later the MAC re-determined (MACSF). MACSF was 1.99 ± 0.32 %, corresponding to 25.6 ± 8.1 % reduction from MACSEVO (P < 0.001). Transdermal fentanyl produces a significant MACSEVO-sparing effect with minimal effect on cardiovascular parameters.

Published: July 2018

Control of swine dysentery with antibiotics is often ineffective due to the resistance of Brachyspira hyodysenteriae. The potential of some herbal-based components against B. hyodysenteriae was previously studied in vitro. This study aims at the evaluation of in vivo efficacy of phytogenic feed additives in the control of swine dysentery

The study involved 64 seven-week old weaned pigs allotted to 4 groups: two were fed on feed supplemented with either Patente Herba® or Patente Herba® Plus, the third received tiamulin (positive control), while the negative control was not given antibiotics or additives. Fecal consistency was recorded daily. The presence of B. hyodysenteriae in the feces was investigated weekly using microbiological assays and the PCR test. Weight gain and feed conversion ratio were calculated for each week, and for the whole experiment.

B. hyodysenteriae was detected in all samples by both methods. The additives showed efficacy in the prevention and control of swine dysentery as only normal and soft stool was observed in the treated groups. By contrast, in the negative control all feces categories were detected. Frequencies of feces categories significantly differed (p<0.001) between feed-supplemented groups and the negative control. Efficacy of both additives in the prevention of SD is comparable to tiamulin, based on insignificant differences in the frequency of the various feces categories.

Beneficial effects of both additives resulted in significantly (p≤0.05) higher weight gain and lower feed conversion ratio in comparison to the negative control. The average weight gains between additive-fed groups and tiamulin-treated group did not differ significantly.

Published: July 2018

During the epizootic of highly pathogenic avian influenza subtype H5N8 in Serbia in the winter of 2016-2017, the highest percent of mortality due to this infection was recorded in mute swans (Cygnus olor). Besides mute swans, avian influenza virus subtype H5N8 was also diagnosed in a small number of hens in rural households. Pancreatic tissues from avian influenza H5N8 positive mute swans and hens that died during this outbreak were collected to determine the character of morphological lesions and the distribution of the viral antigen in this organ. Macroscopic examination of the pancreas of mute swans revealed hemorrhages as well as necrosis, while there were no macroscopic visible lesions in the pancreas of infected hens. Despite the different macroscopic finding, microscopic examination of the pancreas of both infected bird species revealed lesions in the form of acute pancreatitis and multifocal acinar necrosis. The viral antigen was abundantly expressed in the cytoplasm and nucleus of necrotic cells, as well as in macrophages in both examined bird species. Immunohistochemical expression of the viral antigen in the pancreas was strongly consistent with histological lesions. According to the above described findings, it could be concluded that highly pathogenic avian influenza virus H5N8 has a high affinity to pancreatic tissue in both mute swans and hens and the distribution and the character of the lesions in the pancreas are similar in both bird species.

Diseases of the biliary tract are the most common feline hepatic disorders. Cholangitis is the term used to describe inflammation of the biliary tract in felines and can be associated with parasites. Affected animals must undergo clinical or surgical treatment, or a combination of both. In this paper we presented a 10-year-old male, mongrel feline with an obstruction of the biliary tract caused by a rare infection of Platynosomum fastosum.
Open loop control of piezoelectric tube transducer
Authors: Stefanski Frederik , Minorowicz Bartosz
Published: July 2018

This paper is focused on the open loop control of a piezoelectric tube actuator, hindered by a strong hysteresis. The actuator was distinguished with 22 % hysteresis, which hinders the positioning of piezoelectric actuator. One of the possible ways to solve this problem is application of an accurate analytical inversed model of the hysteresis in the control loop. In this paper generalized Prandtl-Ishlinskii model was used for both modeling and open loop control of the piezoelectric actuator. Achieved modeling error does not exceed max. 2.34 % of the whole range of tube deflection. Finally, the inverse hysteresis model was applied to the control line of the tube. For the same input signal (damped sine 0.2 Hz) as for the model estimation the positioning error was max. 4.6 % of the tube deflection. Additionally, for a verification reason three different complex harmonic functions were applied. For the verification functions, still a good positioning was obtained with positioning error of max.4.56 %, 6.75 %and5.6%of the tube deflection.
The influence of chemical composition on the dimensions
Authors: Łyduch Konrad , Gęstwa Wojciech
Published: July 2018

The paper presents the influences of nanofluids, which are used in hardening process, to dimension changes, hardness and microstructure of hardened construction of steel samples. An analysis was also carried out with the use of English methods of cooling abilities of nanofluids environments based on water, solid nanoparticles of Al2O3 and ammoniac water. The results of this experiment show, that only one of specific dimensions of cooled samples, in the distilled water, changed for about 9%, but when using nanofluids this change was smaller. The hardness of alloy materials got a few percent more when nanofluids were used in comparasion to using the distilled water. The gained results allow to conclude the positive influence of nanofluids on parameters of the hardened materials.
What are We Conserving? A Case Study of Mentha longifolia and Allied Species from Lithuania
Authors: Petrulaitis Lukas , Gudžinskas Zigmantas
Published: July 2018

Assessment of the conservation status of a species, first, should be based on its clearly defined taxonomic identity. Insufficient knowledge of certain taxonomic groups may lead to misidentifications, misinterpretations and become an obstacle for conservation. Mentha longifolia, listed as a protected plant species of Lithuania since 1981, belongs to a taxonomically complex group of species. The aim of this research was to examine available herbarium specimens of M. longifolia and verify their identification, specify distribution of this species in Lithuania and evaluate its conservation status in the country. The study was based on the analysis of herbarium specimens and information provided in references and databases. We studied a total of 93 specimens initially identified as M. longifolia. Morphological features of 30 leaves (leaf length, leaf width, petiole length, distance from leaf base to the widest place, length of leaf tooth) of both M. longifolia and M. ×villosa were measured on herbarium specimens. After the revision of herbarium specimens, we revealed that 37.6% of specimens initially identified as M. longifolia belong to other species (mostly to M. ×villosa) and 29.0% of specimens cannot be identified precisely because of the early stage of development. Only 33.4% of M. longifolia specimens were identified precisely. Thus, M. longifolia, previously supposed as quite widespread in Lithuania, after the revision appeared to be restricted mainly to the southern and south-eastern parts of the country. Applying the IUCN criteria, M. longifolia was evaluated as data deficient (DD) species. Analysis of leaf morphological traits revealed that M. longifolia and M. ×villosa can be differentiated by the length and the width of leaf blade, the distance from leaf base to the widest part of leaf and by the ratio between the length and the width of middle cauline leaves. This study revealed that taxonomic revision of the genus Mentha in Lithuania is required. Distribution of species, ecology and state of populations, impact of alien species on native congeners should be estimated in the future.
Structure and Dynamics of Algal Communities in Small River of the Republic of Karelia (Rusia)
Authors: Komulaynen Sergey
Published: July 2018

Distribution of phytoplankton, phytoperiphyton and microphytobenthos communities was simultaneously studied in the River Lihzma (Republic of Karelia, Russia). Comparison includes both taxonomic and quantitative parameters along river continuum. Special attention was given to the analysis of causes of spatial inhomogeneity of algal communities. In the studied river, the pattern and trends of dynamics in the community were dependent on high current velocities and the alternation of lake, pool, and riffle zones. Algae are constantly removed from bottom biotopes, attached forms are detached from their substrate and are transported by the stream, and planktonic forms settle down, disturbing the distinctive characteristics of communities and resulting in the formation of “mixed” communities.
Creation of a Network of Seed Sites for In-Situ Conservation of Medicinal and Aromatic Plant Genetic Resources in Lithuania
Authors: Labokas Juozas , Karpavičienė Birutė
Published: July 2018

Twenty six seed (genetic) sites were established for long-term in-situ conservation of medicinal and aromatic plant (MAP) genetic resources in Lithuania over the period 2006–2017. The sites vary in size from 0.4 to 38.0 ha with an average of 7.2 ha. Most of the sites (73%) occur in the existing protected areas. They represent 10 of 22 physical geographical areas of Lithuania and accommodate 120 priority MAP species, which is about 89% of the national priority list. Prioritization of MAP species was based on the monographs of European Pharmacopoeia, European Medicines Agency, World Health Organization as well as German Phytotherapeutic Monographs and other regional and national medicinal plant references. A concept was followed of the dual function and perception of food as medicine, and, vice versa, an approach based on a co-evolutionary relationship between human food and medicine. It was established that only 46 priority species, or 34% of the national priority list, were represented by five and more populations, which is considered as minimum for long-term in-situ conservation. The future conservation planning efforts should focus on at least 15 unrepresented species, 49 species represented at 1–2 sites each and 25 species represented at 3–4 sites each. The MAP site network should expand by covering preferably the remaining 12 physical geographical areas of the country.
Local Contributions of Forests to Economic Growth of Peru: A Case of Pinus radiata Plantations
Authors: Canchari Nadia Nora Urriola , Baral Pradeep , Wang Lanhui
Published: July 2018

The economic contributions from forestry sector remain relatively important in all developing economies. Over the past few decades, value added in the forestry sector of these economies has gradually increased. Consequently, the need for a detailed and accurate assessment of the economic contribution of the sector has grown in order to gain the attention of the policy makers and to highlight its importance in poverty alleviation and sustainable development. Contrarily, In Peru, forestry sector continues to be left behind due to faster growth in other sectors of economy. Despite having considerable forest resources, the full extent of economic contributions of the forestry sector to local as well as the national economy is still poorly understood. Sparsity of up-to-date data on value added in the forestry sector and a general disregard to any forests other than Amazonian rainforests have compounded the already existing situation. In this context, this paper aimed at making an empirical analysis of the direct contributions of the forestry sector to the local economy of Peru in the short run using an annual time series data from 2007 to 2016. The Pinus radiata plantation forests of the Department of Ayacucho located in the Southern Peruvian Andes served as a case for this study. The results revealed nominal but significant contributions of the Pinus radiata forests to the economic growth of the Department of Ayacucho. As our study was limited only to direct cash benefits, future studies should also take into account informal and non-cash benefits in order to fully apprehend the economic contributions of the forestry sector to local and national economy.
Use of scenario development and personal learning environment and networks (PLE&N) to support curriculum co-creation
Authors: Tsui Eric , Dragicevic Nikolina
Published: July 2018

In much of the current discussions on business environments, a recurring theme both for academics and practitioners is that it is marked by inherent uncertainty (unknown unknowns). Hence, knowledge workers must have skills and understanding of the possible ways to navigate through and adapt to constant change. However, the tendency of prevailing approaches to curriculum development to focus on (static) learning outcomes, we argue, is not appropriate to train young people to adapt to the unpredictable working environment. Instead, more dynamic approaches to curriculum are required, which would instead focus on learning as a continuous relearning and emergent process of adaptation and stimulate students' inquiry and intellectual and creative skills. This paper approaches the issue by discussing the opportunities of using scenario thinking and development together with a personal learning environment and network (PLE&N) for co-creating a curriculum with students, teachers, and practitioners in higher education. In short, the methodology underpinning scenario development recognizes that uncertainty can be best dealt with and understood from the perspective of a range of possibilities and multiple futures through a facilitated, coherently structured process. PLE&N, on the other hand, serves as a learning space which stimulates self-regulated and network-based learning. The paper contends that curriculum informed by such a design methodology would lead to more frequent and appropriate updates as well as equip students with skills to work in a volatile, uncertain, complex, and ambiguous (VUCA) environment.

Openness is an expression of an enterprise’s ability to adapt to changing environment conditions and its ability to cooperate with different types of partners. A given company’s openness shows its readiness for the creation of dynamics of many business processes, including the creation of its competitive advantage. Due to the nature of today’s enterprises’ environment, mainly its “high velocity” & “complexity” attributes, openness of companies has to be multifaceted. Organization-customer relationships, called co-creation, are one of such facets. The capacity for effective co-creation gives a company the ability to gain a competitive advantage along with the chance for its permanent dynamization and sustainability. The main purpose of the paper is to present the framework and algorithm of co-creation as a method of reducing the complexity of the environment and dynamizing companies’ competitive advantages. A review of literature in the areas of open organization, open culture, partnership, co-creation, and competitive advantage provides a basis for understanding the process of co-creation. Collected data show that the activity of enterprises in this process is a key factor in the reduction of complexity of a company’s environment and an important stimulator of the dynamization of a company’s competitive advantage. The authors’ own CATI questionnaire survey research conducted in Poland showed the level of preparation Polish SMEs have to co-create.

This research examines the moderating effect of family ownership over the relationship between board independence and earnings management. Using information of industrial companies indexed on Amman Stock Exchange, this research provides evidence of negative relationship between board independence and earnings management, proposing that higher percentage of board independence is related with more effective monitoring to reduce earnings management. Moreover, the results document that the relationship between board independence and earnings management becomes weak when there is an interaction with family ownership control. These outcomes indicate that an increase in the percentage of independent directors to mitigate earnings management is less likely to be influential in the case of family controlled firms. The results of this research could be valuable to regulators in their efforts to restrict the incidence of earnings management and improve the quality of monitoring mechanisms, especially in an environment where the capital market is still evolving and the legal protection and law enforcement are weak.

Published: July 2018

One of the aspects of the university institutional renewal should be to improve the organization of conditions for the support of the student life opportunities. Determination of the student’s needs and expectations in diagnosing his resources, opportunities and environment (university / family / local environment) will facilitate the organization of services for the student. The existing services system is fragmented causing organizational chaos and disorientation of the recipient and does not take into account the individual characteristics of the student. The method of an individual case may be an alternative to operating system in its extended formula. Its conception is divided into two stages: the diagnosis of student’s needs and expectations and the individual assistance plan in achieving educational goals through the personal resources development and a more or less inner circle at the university. It has been concluded that organization improvement of the higher education institution activity should take place particularly through creating conditions conducive to the development of student potential. The student (life) opportunities building should take into account the individual needs, expectations and resources of the student as well as the organizational capabilities of the university, the family and the local environment. The responsibility of the existing units of the university is to provide support and assistance to the student although they operate in accordance with their own rules, clearly defined tasks and competencies without creating an entire (holistic) system for supporting the student potential in the age of globalization. The proposed method of organizing the conditions at the university permitting us to identify and develop the student potential to meet their needs in the perspective of multidimensional existence may be an individualized approach to the student.
