Rola wczesnej edukacji i opieki w ograniczaniu skutków ubóstwa wśród dzieci
Authors: Subocz Elżbieta
Published: September 2018

This article attempts to answer the question: what role does the process of early childhood education and care play in reducing the effects of poverty among children? The main argument of the article states that education (started as early and lasting as long as possible) is the only chance to limit the negative consequences of poverty, as well as to overcome the intergenerational transmission of poverty and social exclusion. Relying on the results of foreign (mostly American) surveys, it has been proven that good quality early childhood education and care is beneficial for children living in poverty, as well as for society as a whole. It positively influences the social and emotional development of children, their language skills and school achievements. Children who benefited from institutions / programmes for early childhood education and care, in adulthood do better in the labour market, have higher earnings and are less likely to seek stimulants. Society bears lower costs of special education, anti-social behaviour, criminal proceedings, social welfare and health of young people and adults.
Możliwości współczesnej recepcji utworów Stanisława Jachowicza, dydaktycznej literatury dziewiętnastowiecznej
Authors: Telatyńska Beata
Published: September 2018

Prior to the nineteenth century, literature aimed particularly at children did not exist. Only romanticism saw the great potential that the engagement with the topic of childhood offered. In Poland Stanislaw Jachowicz – Polish storyteller, educator and charity activist-achieved s significant successes in this field. In this article, the author presents Jachowicz’s work from two perspectives. By conducting a nineteenth century and a contemporary reading of his narrations, she examines the possible contexts of reading Jachowicz’s didactic literature, concentrating primarily on his fairy tales. Although, from the point of view of contemporary pedagogy, Jachowicz’s educational methods are outdated and inadequate to give guidance on the realities that the children of today face, one can find universal elements in the writer’s work, for example, respect for another person, work, money or empathy. The modern reader is invited to gain a better understanding of the realities of the nineteenth century family and confront these insights with the challenges and the hopes of the present day.

Makarenkowskie odczyty o wychowaniu dla rodziców w optyce Foucaultowskiej kategorii urządzania

Published: September 2018

The subject of our interest is the rhetoric of Makarenko’s readings/interpretations of upbringing designated for parents. We would like to subject it to consideration in the prospect/perspective of Foucault’s governmentality category, understood as a specific metacategory/joint category connecting the axes of power (the Soviet power), knowledge (political economy), and the subject (homo sovieticus). Applying the governmentality category provides for the possibility of attempting to reconstruct traces of tangle/discursive relations and undiscursive elements of the policy of arranging a family which is a component of a broader policy of the Soviet state aimed at “forging” the new Soviet man. In this context, we will recognize Makarenko’s pedagogy as a kind of conceptualization and implementation of the policy of the Soviet state at the family level, having the goal of shaping a man of collective mentality, completely subordinated to the Soviet state, with standardized and ideologized consciousness.

The Pulse Wave Velocity is Linearly Correlated with Resting Systolic and Diastolic Blood Pressure in Hypertensive Patients
Authors: Elka Kana , Rotty Monique , Winata Johan , Pangemanan Janry , Panda A. Lucia
Published: September 2018

Introduction: Aortic stiffness is an independent predictor for cardiovascular event. If arteries lose their natural elasticity, systolic blood pressure become higher and dia­stolic blood pressure become lower. Method of evaluating arterial stiffness is aortic pulse wave velocity (PWV). Therefore, PWV has a potential application for screening vascular damage in large population.2 Recent reports have shown that PWV obtained by noninvasive automatic devices (i.e. tonometry, cuff pressure) is not only a marker of vascular damages, but also a prognostic predictor in patients with hypertension.3 The aim of this study is to investigate the correlation between PWV and systolic and diastolic blood pressure.

Methods : Male hypertensive patients, aged 40-60 years old who underwent Doppler Vascular were included in this study. The measurement of carotid-femoral PWV is made by dividing the distance (from the carotid point to the femoral point) by the so-called transit time (the time of travel of the foot of the wave over the distance). Hence, PWV = D (meters)/Dt (seconds). The correlation between PWV and systolic and diastolic blood pressure were analysed using linear regression test.

Results : A total 40 patients were included in this study. Those were significant correla­tion between PWV and systolic (R=0.473, p=0.002) and diastolic (R=0.454, p=0.003) blood pressure.

Conclusion : increasing PWV is linearly associated with systolic and diastolic blood pressure.

 

Abstrak

Pendahuluan: Kekakuan aorta adalah prediktor independen untuk kejadian kardiovaskular. Jika elastisitas alami arteri hilang, tekanan darah sistolik menjadi lebih tinggi dan tekanan darah diastolik menjadi lebih rendah. Metode evaluasi kekakuan arteri adalah kecepatan gelombang pulsasi (pulse wave velocity/PWV). Oleh karena itu, PWV dapat diterapkan untuk skrining kerusakan vaskular pada populasi besar.2 Laporan terbaru menunjukkan bahwa PWV yang diperoleh dengan perangkat otomatis non-invasif (yaitu tonometri, tekanan manset) tidak hanya merupakan penanda kerusakan vaskular, tetapi juga prediktor prognostik pada pasien dengan hipertensi.3 Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara PWV dan tekanan darah sistolik dan diastolik.

Metode: Pasien pria dengan hipertensi, berusia 40-60 tahun yang menjalani Doppler Vascular dimasukkan dalam penelitian ini. Pengukuran PWV karotid-femoralis dilakukan dengan membagi jarak (dari titik karotid ke titik femoral) dengan waktu transit. Oleh karena itu, PWV = D (meter) / Dt (detik). Korelasi antara tekanan darah PWV dan sistolik dan diastolik dianalisis dengan menggunakan uji regresi linier.

Hasil: Sebanyak 40 pasien dimasukkan dalam penelitian ini. Itu adalah korelasi yang signifikan antara tekanan darah PWV dan sistolik (R = 0,473, p = 0,002) dan diastolik (R = 0,454, p = 0,003).

Kesimpulan: Peningkatan PWV berhubungan linear dengan tekanan darah sistolik dan diastolik.

Self-Presentation in Interracial Settings: The Competence Downshift by White Liberals
Authors: Dupree Cydney H. , Fiske Susan
Published: September 2018

Most Whites, particularly socio-political liberals, now endorse racial equality. Archival and experimental research reveals a subtle but reliable ironic consequence: White liberals self-present less competence to minorities than to other Whites—that is, they patronize minorities stereotyped as lower status and less competent. In an initial archival demonstration of the competence downshift, Study 1 examined the content of White Republican and Democratic presidential candidates’ campaign speeches. Although Republican candidates did not significantly shift language based on audience racial composition, Democratic candidates used less competence-related language to minority audiences than to White audiences. Across five experiments (total N = 2,157), White participants responded to a Black or White hypothetical (Studies 2, 3, 4, S1) or ostensibly real (Study 5) interaction partner. Three indicators of self-presentation converged: sophistication of vocabulary selected for an assignment, competence-related traits selected for an introduction, and competence-related content of brief, open-ended introductions. Conservatism indicators included: self-reported political affiliation (liberal-conservative), Right-Wing Authoritarianism (values-based conservatism) and Social Dominance Orientation (hierarchy-based conservatism). Internal meta-analyses revealed that liberals—but not conservatives—presented less competence to Black interaction partners than to White ones. The simple effect was small but significant across studies, and most reliable for the self-reported measure of conservatism. This possibly unintentional but ultimately patronizing competence-downshift suggests that well-intentioned liberal Whites may draw on low-status/competence stereotypes to affiliate with minorities.

Published: September 2018

Inflammatory markers including C-Reactive Protein (CRP) are increasingly used within research and clinical settings. Yet, varying methodologies for cleaning immunoassay data with out of range (OOR) samples may alter characteristic levels of CRP, thereby obscuring interpretation and reliability. This study investigated the influence of eight immunoassay OOR data treatment techniques on salivary CRP (sCRP) samples from at-risk adolescents. Participants from the ‘Sleep and Education: learning New Skills Early’ (SENSE) Study were 86 adolescents at-risk for depression (50 female), aged 14.29 years (SD=1.04). ANOVA results showed no statistically significant differences in average morning (F(7, 590)=1.24, p=.28) and evening (F(7, 599)=1.29, p=.25) values produced by each OOR data cleaning technique. However, varying techniques produced differences in the magnitude of Pearson’s correlations between consecutive saliva samples (r’s between .27 – .78), and influenced the significance of a sCRP diurnal pattern; two techniques produced statistically higher morning than evening sCRP levels (t(85)=2.70, p=.01 and t(85)=2.67, p=.01), whereas six techniques failed to find statistical differences between morning and evening sCRP levels (p’s >.05). Varying techniques also produced statistically divergent associations between sCRP and age and depressive symptoms. Results from this study provide evidence for the temporal stability of sCRP among adolescents, show winsorization as an effective OOR data management technique, and highlight the influence of methodological decisions in cleaning salivary biomarker data and the need for consistency within the field.

Cytotoxic activity of crude extracts of Dendrobium amoenum and detection of bioactive compounds by GC-MS
Authors: Paudel Mukti Ram , Pant Bijaya
Published: September 2018

Dendrobium amoenum is an epiphytic orchid used as tonic because it has many derivatives of phenols. The crude extract of this orchid has been shown to have antioxidant activity. The objectives of this research are to explore the cytotoxic activity of antioxidant-rich crude extract against the human cervical carcinoma and glioblastoma cell lines by MTT assay and to detect the compounds by GC-MS. Methanol (DAM) extract of D. amoenum showed high cell growth inhibition percentage against the tested cell lines. DAM extract showed high cytotoxic activity against HeLa cells (IC50 – 110.22 μg/ml) and least activity against U-251 cells (IC50 – 550.55 μg/ml). Thirteen compounds were detected and identified in the extract. Based on abundance, four major compounds detected were: (E)-13-docosenoic acid; oleic acid; 11-octadecenoic acid, methyl ester; and hexadecanoic acid, 2,3-dihydroxypropyl ester. The cytotoxic activity of DAM extract is probably due to the presence of these bioactive compounds, confirmation of which needs further investigation. The result also highlighted the potential of this orchid as the source of natural anticancer drug and to explore their isolation, identification and characterization.Botanica Orientalis – Journal of Plant Science (2017) 11: 38–42

Published: September 2018

BACKGROUND: The distribution of hepatitis C (HCV) infection in Canada signals a widening gap between Indigenous and non-Indigenous people. Current evidence demonstrates that the rate of HCV infection among Indigenous people is at least five times higher than the rest of Canada. This analysis provides a reconciliatory response, which exposes the colonial etiology of the HCV gap in Canada and proposes potential anti-colonial approaches to HCV wellness and health care for Indigenous people. Methods: This analysis applies Two-Eyed Seeing as a reconciliatory methodology to advance the understanding of HCV burden and identify the key elements of responsive HCV care in the context of Indigenous nations in Canada. Results: The analysis underlines the colonial distribution of HCV burden in Canada, highlights Indigenous perspectives on HCV infection, hypothesizes a clinical pathway for the underlying colonial etiology of HCV infection, and identifies Indigenous healing as a promising anti-colonial conceptual approach to HCV wellness and health care among Indigenous people. Conclusions: In the eyes of Indigenous people, HCV infection is a colonial illness that entails healing as an anti-colonial approach to achieving wellness and gaining health. Future empirical research should elaborate on the colonial HCV pathway hypothesis and inform the development of a framework for HCV healing among Indigenous people in Canada.
THE INSTABILITY OF SLIPPING FLOW IN A CURVILINEAR POROUS MICROCHANNEL
Authors: Kovetska Y.Y. , Skitsko A.I. , Sorokina T.V.
Published: September 2018

The hydrodynamic instability of flow with slippage in a curvilinear porous microchannel between two stationary concentric cylinders is investigated. Unperturbed velocity profiles for a flow with slip are obtained. The problem of linear instability is solved numerically, using the collocation method. Calculations showed that an increase in the coefficient of slippage, the porosity of the medium and the width of the channel leads to an increase in the occupancy of the velocity profile of the undisturbed flow (the profile becomes more flat). This, in turn, leads to an increase in the critical values of Dean number and the critical wave length of the perturbation, which determine the instability criteria for the flow. It is also shown that for σ> 0 the dependences of the critical Dean number on the parameter η have a minimum observed at η = 0.5. With decrease in channel width and permeability, this effect is leveled.
PROSPECTS FOR APPLICATION OF COGENERATION TECHNOLOGIES IN MUNICIPAL ENERGY
Authors: Klimenko V.N.
Published: September 2018

The article considers conditions and possibilities for installing cogeneration units (CUs) in district heating boiler houses. The main requirement to do it is the equality of the CUs’ heat capacity and the heat capacity of the boilers that are going to be replaced.

Because the fuel (natural gas) consumption increases due to such replacement, it is necessary to determine the conditions, taking into account the constant growth of energy carriers’ prices, under which the transition to cogeneration technologies in the heat supply system will be feasible, i.е. the project will make a profit and ensure the reasonable payback period. For this purpose, the relationships between the profitability of the project, the economic indicators of the equipment included in the cogeneration unit, and the price of energy carriers are suggested. An analysis performed with the help of these relationships showed that the cogeneration unit of the same thermal capacity as the boiler (or boilers), which is going to be replaced, in comparison with CU installed on the basis of a generating unit definitely requires an increase in fuel consumption, and the profit, determined as the difference between income from generated electricity sales and fuel purchase costs, becomes dependent on the prices of natural gas and electricity, as well as the cost-effectiveness of the equipment for cogeneration. With certain combinations of these parameters, the cogeneration unit, installed on the basis of heat generation, may not be profitable, but unprofitable. Moreover, as natural gas price increases and electricity tariff remains fixed, CUs, designed as profitable, may become unprofitable. These conditions are considered in the article. Relationships between the CU’s parameters and tariffs for the natural gas and electricity, which determine the area of profitable work of the cogeneration unit, are obtained. Given the current prices for energy carriers, the design of the CU based on the communal heat supply comes to the selection of the equipment that ensures the profitability of the installation that is sufficient for the recoupment of capital investments within 2-3 years. At the same time, the acceptable limits of the possible increase in the gas/electricity tariffs ratio should be determined.

The main conclusion: the cogeneration unit based on district heat supply with a positive economic effect can be installed only if certain economic and technological conditions, which must be taken into account when designing it, are observed.

OBJECTIVE

Hypoperfusion during carotid artery cross-clamping (CC) for carotid endarterectomy (CEA) may result in the major complication of perioperative stroke. Median nerve somatosensory evoked potential (MNSSEP) monitoring, which is an established method for the prediction of cerebral ischemia, has low sensitivity in detecting such hypoperfusion. In this study the authors sought to explore the limitations of MNSSEP monitoring compared to tibial nerve somatosensory evoked potential (TNSSEP) monitoring for the detection of CC-related hypoperfusion.

METHODS

The authors retrospectively analyzed data from patients who underwent unilateral CEA with routine shunt use. All patients underwent preoperative magnetic resonance angiography and were monitored for intraoperative cerebral ischemia by using MNSSEP, TNSSEP, and carotid stump pressure during CC. First, the frequency of MNSSEP and TNSSEP changes during CC were analyzed. Subsequently, variables related to stump pressure were determined by using linear analysis and those related to each of the somatosensory evoked potential (SSEP) changes were determined by using logistic regression analysis.

RESULTS

A total of 94 patients (mean age 74 years) were included in the study. TNSSEP identified a greater number of SSEP changes during CC than MNSSEP (20.2% vs 11.7%; p < 0.05). Linear regression analysis demonstrated that hypoplasia of the contralateral proximal segment of the anterior cerebral artery (A1 hypoplasia) (p < 0.01) and hypoplasia of the ipsilateral precommunicating segment of the posterior cerebral artery (P1 hypoplasia) (p = 0.02) independently and negatively correlated with stump pressure. Both contralateral A1 hypoplasia (OR 26.25, 95% CI 4.52–152.51) and ipsilateral P1 hypoplasia (OR 8.75, 95% CI 1.83–41.94) were independently related to the TNSSEP changes. However, only ipsilateral P1 hypoplasia (OR 8.76, 95% CI 1.61–47.67) was independently related to MNSSEP changes.

CONCLUSIONS

TNSSEP monitoring appears to be superior to MNSSEP in detecting CC-related hypoperfusion. Correlation with stump pressure and SSEP changes indicates that TNSSEP, and not MNSSEP monitoring, is a reliable indicator of cerebral ischemia in the territory of the anterior cerebral artery.
A comparison between threshold criterion and amplitude criterion in transcranial motor evoked potentials during surgery for supratentorial lesions
Authors: Abboud Tammam , Schwarz Cindy , Westphal Manfred , Martens Tobias
Published: September 2018

OBJECTIVE

The aim of this study was to compare sensitivity and specificity between the novel threshold and amplitude criteria for motor evoked potentials (MEPs) monitoring after transcranial electrical stimulation (TES) during surgery for supratentorial lesions in the same patient cohort.

METHODS

One hundred twenty-six patients were included. All procedures were performed under general anesthesia. Craniotomies did not expose motor cortex, so that direct mapping was less suitable. After TES, MEPs were recorded bilaterally from abductor pollicis brevis (APB), from orbicularis oris (OO), and/or from tibialis anterior (TA). The percentage increase in the threshold level was assessed and considered significant if it exceeded by more than 20% on the affected side the percentage increase on the unaffected side. Amplitude on the affected side was measured with a stimulus intensity of 150% of the threshold level set for each muscle.

RESULTS

Eighteen of 126 patients showed a significant change in the threshold level as well as an amplitude reduction of more than 50% in MEPs recorded from APB, and 15 of the patients had postoperative deterioration of motor function of the arm (temporary in 8 cases and permanent in 7 [true-positive and false-negative results]). Recording from TA was performed in 66 patients; 4 developed postoperative deterioration of motor function of the leg (temporary in 3 cases and permanent in 1), and showed a significant change in the threshold level, and an amplitude reduction of more than 50% occurred in 1 patient. An amplitude reduction of more than 50% occurred in another 10 patients, without a significant change in the threshold level or postoperative deterioration. Recording from OO was performed in 61 patients; 3 developed postoperative deterioration of motor function of facial muscles (temporary in 2 cases and permanent in 1) and had a significant change in the threshold level, and 2 of the patients had an amplitude reduction of more than 50%. Another 6 patients had an amplitude reduction of more than 50% but no significant change in the threshold level or postoperative deterioration.

Sensitivity of the threshold criterion was 100% when MEPs were recorded from APB, OO, or TA, and its specificity was 97%, 100%, and 100%, respectively. Sensitivity of the amplitude criterion was 100%, 67%, and 25%, with a specificity of 97%, 90%, and 84%, respectively.

CONCLUSIONS

The threshold criterion was comparable to the amplitude criterion with a stimulus intensity set at 150% of the threshold level regarding sensitivity and specificity when recording MEPs from APB, and superior to it when recording from TA or OO.
The full-endoscopic uniportal technique for decompression of the anterior craniocervical junction using the retropharyngeal approach: an anatomical feasibility study in human cadavers and review of the literature
Authors: Ruetten Sebastian , Hahn Patrick , Oezdemir Semih , Baraliakos Xenophon , Merk Harry , Godolias Georgios , Komp Martin
Published: September 2018

OBJECTIVE

Acute or progressive myelopathy may necessitate direct anterior decompression of the craniocervical junction and odontoidectomy. Different techniques with individual advantages and disadvantages can be used. In addition to the gold standard—the transoral approach—there is also increasing experience with the endoscopic transnasal technique. Other alternative methods are also being developed to reduce technical and perioperative problems. The aim of this anatomical study was to investigate the feasibility of the full-endoscopic uniportal technique with a retropharyngeal approach for decompression of the craniocervical junction, taking into consideration the specific advantages and disadvantages compared with conventional methods and the currently available data in the literature.

METHODS

Five fresh adult cadavers were operated on. The endoscope used has a shaft cross-section of 6.9 × 5.9 mm and a 25° viewing angle. It contains an eccentric intraendoscopic working channel with a diameter of 4.1 mm. An anterior retropharyngeal approach was used. The anatomical structures of the anterior craniocervical junction were dissected and the bulbomedullary junction was decompressed.

RESULTS

The planned steps of the operation were performed in all cadavers. The retropharyngeal approach allowed the target region to be accessed easily. The anatomical structures of the anterior craniocervical junction could be identified and dissected. The bulbomedullary junction could be adequately decompressed. No resections of the anterior arch of the atlas were necessary in the odontoidectomy.

CONCLUSIONS

Using the full-endoscopic uniportal technique with an anterior retropharyngeal approach, the craniocervical region can be adequately reached, dissected, and decompressed. This is a minimally invasive technique with the known advantages of an endoscopic procedure under continuous irrigation. The retropharyngeal approach allows direct, sterile access. The instruments are available for clinical use and have been established for years in other operations of the entire spine.

Published: September 2018

OBJECTIVE

Diffuse intrinsic pontine glioma (DIPG) is a highly aggressive and lethal brainstem tumor in children. In the 1980s, routine biopsy at presentation was abandoned since it was claimed “unnecessary” for diagnosis. In the last decade, however, several groups have reincorporated this procedure as standard of care or in the context of clinical trials. Expert neurosurgical teams report no mortality and acceptable morbidity, and no relevant complications have been previously described. The aim of this study was to review needle tract dissemination as a potential complication in DIPG.

METHODS

The authors retrospectively analyzed the incidence of dissemination through surgical tracts in DIPG patients who underwent biopsy procedures at diagnosis in 3 dedicated centers. Clinical records and images as well as radiation dosimetry from diagnosis to relapse were reviewed.

RESULTS

Four patients (2 boys and 2 girls, age range 6–12 years) had surgical tract dissemination: in 3 cases in the needle tract and in 1 case in the Ommaya catheter tract. The median time from biopsy to identification of dissemination was 5 months (range 4–6 months). The median overall survival was 11 months (range 7–12 months). Disseminated lesions were in the marginal radiotherapy field (n = 2), out of the field (n = 1), and in the radiotherapy field (n = 1).

CONCLUSIONS

Although surgical tract dissemination in DIPG is a rare complication (associated with 2.4% of procedures in this study), it should be mentioned to patients and family when procedures involving a surgical tract are proposed. The inclusion of the needle tract in the radiotherapy field may have only limited benefit. Future studies are warranted to explore the benefit of larger radiotherapy fields in patients with DIPG.
Las consultoras de comunicación en Cataluña: 25 años de creación de espacios para el diálogo
Authors: Buil Gazol Pilar , Rodríguez-Salcedo Natalia
Published: September 2018

Las consultoras de comunicación comenzaron en España hace más de medio siglo. En noviembre de 1960 nació la primera agencia de relaciones públicas (RP): Sociedad Anónima Española de Relaciones Públicas (S.A.E. de RP) en Barcelona. Sin embargo, las circunstancias económicas y políticas no permitieron el pleno desarrollo de los servicios de las agencias hasta la década 1990. En los últimos años, sin embargo, el contexto de crisis económica parece haber afectado al ritmo de crecimiento. Ante esta realidad, el presente estudio aborda, tras un breve recorrido histórico por los orígenes, la evolución de las agencias de RP en Cataluña en los últimos 25 años. El objetivo reside en analizar el desarrollo de las consultoras con sede en Cataluña durante los últimos 25 años con el fin de contribuir al conocimiento sobre la historia y naturaleza de esta disciplina en el marco geográfico donde se inició. Para llevar a cabo esta investigación, se diseñó un cuestionario de diez preguntas sobre la trayectoria histórica de las agencias en Cataluña, que se envió a casi 60 empresas desde mayo de 2014 hasta mayo de 2015. Los resultados reflejan que, a pesar de la crisis, han surgido nuevas agencias. Además, se observa un desarrollo del área de las RP digitales y una preferencia por el uso del término “comunicación” en detrimento del de “relaciones públicas”.

El presente trabajo analiza la adaptación al contexto digital de la revista Vogue, como paradigma del periodismo de moda, teniendo en cuenta la influencia que esta publicación ejerce sobre dicho sector. Tras una introducción contextual de las revistas femeninas, se examina Vogue como icono en su sector para posteriormente llevar a cabo el análisis de contenido de su web a través de las siguientes variables: audiencia, secciones principales, tipo de estructura, presencia de sus editoras en portada, formatos publicitarios, mecanismos de promoción en redes, distribución de los contenidos principales (moda y belleza), tipo y número de interactividad con las lectoras y uso del brand placement con las marcas selectas. Como principal conclusión, se puede decir que Internet se ha convertido en una herramienta aliada de las revistas de moda y que las redes sociales han resultado ser una gran oportunidad, si bien surgen ahora nuevos retos. En el caso de Vogue, cabe destacar que la revista ha ampliado su audiencia no solo cuantitativamente, sino también en nuevos perfiles, como por ejemplo la cobertura de una nueva franja de edad más joven.
Las “Pajaritas de papel” de Jaime Campmany (1966-1970): aportación al periodismo literario español
Authors: Fernández Jiménez Antonio
Published: September 2018

Este artículo da a conocer a grandes rasgos la primera etapa de Jaime Campmany en el ejercicio de la columna periodística a través de la escritura de unos artículos literarios que su autor llamó ‘Pajaritas de papel’, publicados diariamente en Arriba entre 1966 y 1970. De gran calidad literaria y enmarcadas en una época en que se gestaba un nuevo periodismo, las ‘Pajaritas’ constituyen una clara contribución al estudio del periodismo literario de finales de la posguerra española por cuanto pudo expresar Campmany en un tiempo en el que todavía la prensa sufría las trabas de la censura. Por ello y además, podemos considerarlas como un precedente preclaro al apogeo de la columna de opinión en las décadas sucesivas.

El proyecto de los espacios sociales de aprendizaje en la Universidad Española se inició como parte del cambio de modelo educativo propuesto por el proceso de Bolonia. Dichos espacios los conforman todos los lugares que no son los aularios y que ayudan a completar el aprendizaje formal. En la presente investigación se reflexiona sobre estos espacios y las actividades que se desarrollan en ellos, donde los estudiantes adquieren las competencias y habilidades más demandadas por el mercado laboral, especialmente las llamadas competencias emprendedoras. Anualmente se organiza un maratón de emprendimiento llamado Barcelona Thinking Challenge en la UAO CEU. Dicha actividad es un espacio de aprendizaje donde los estudiantes adquieren competencias transversales y específicas, trabajando en equipos formados por estudiantes de diferentes cursos, universidades y profesionales. Se analizan los resultados de un estudio de encuesta que valora cuál ha sido la visión general de este maratón de emprendimiento social y qué competencias emprendedoras ha permitido desarrollar en los participantes. Los resultados permiten destacar que los partícipes valoran positivamente esta actividad emprendedora. Se muestra un alto desarrollo en las competencias relacionadas con trabajar en equipo, liderazgo y aplicación de conocimientos adquiridos en la universidad a la resolución de problemas.

Adequate water availability in irrigation systems is an important factor in the success of irrigation agriculture, including Sungai Tabuk irrigation system which land is  planted with rice paddy, fields rice paddy and crops. The availability of water in Kecamatan Tabuk River was calculated by dependable flow analysis using flow data from Mock method calculation. The model of rainfall-flow relationship with the monthly interval used was Mock Method, and 80%  dependable flow was used to calculate the availability of the irrigation water. Based on the  rainfall and evapotranspiration data (Mock method) in irrigation system of Sungai Tabuk area, the average flow per year of 5.758 m3 / sec obtained. With the highest flow occurred in March of 9.405m3 / sec and the lowest flow was in September at 1.616 m3 / sec. The 80% dependable flow was an average of 3.504 m3 / sec with the highest 80% of the highest dependable flow recorded in February of 7.37 m3 / sec and the lowest flow was in October which 80% flow was  0.24 m3 / sec. The calculation of irrigation water needed was based on KP-01. The calculation results showed that the average water demand was 2.690 m3 / sec with the beginning of planting on December I by using ordinary rice-ordinary rice planting pattern; while the average water demand for crops was 0.029 m3 / sec. From the analysis, the availability of irrigation water of Sungai Tabuk (average value of 3,504 m3 / sec) can fulfil the irrigation water requirement (average value of 2,690 + 0,029 = 2,719 m3 / second).

Reduced forest products cause also reduced of large-dimensional wood that has high quality. One alternative to solve the problem is by doing laminate engineering by combining different quality wooden layers into specific sized beams as desired. The type of wood and the position of layer give effect to the laminate beam capacity. The aim of this research was to find out the flexural capacity (MOR) of Mahang and Meranti wood laminated beams which layers were varied which then the result of the laminated beam was compared with the  solid beams. There were 3 types of laminate specimens made with dimension 5x7x76 cm3 which consisted of 7 layers; BL K1 beam consisted of 2 layers of Meranti wood at the top and bottom of the beam and 5 layers of Mahang in the middle; BL K2 beam consisted of 4 layers of Meranti wood at the top and bottom of the beam, and 3 layers of Mahang in the middle; and BL K3 beam consisted  of 6 layers of Meranti wood at the top and bottom of the beam and 1 layer of Mahang in the middle. The test results showed that the use of wood of higher specific gravity at the outermost layer has increased the flexural capacity (MOR) and modulus of elasticity (MOE), particularly in laminated beams (Meranti wood and Mahang wood) with the same numbers of layers. Moreover, in same number or greater layer proportion between Mahang and Meranti wood, the result showed the increased of MOR and MOE of laminated beams compared with solid beam that has low specific gravity (Mahang).
