Planning for the Future
Authors: Hutchins Bryan C. , Meece Judith L. , Byun Soo-yong , Farmer Thomas W. 
Published: July 2019

The purpose of this study was to explore the postsecondary educational and occupational expectations of work-bound rural youth. Three groups of work-bound youth were identified (work-bound, work-bound with future educational plans, and work-bound but unsure/undecided about postsecondary education), and each group was compared to college-bound rural youth using results from a recent national investigation of the educational and occupational aspirations of rural youth. Results indicated that the majority of rural youth in this study planned to continue their education after high school (56%), followed by 34% who planned to work and further their education. Results of logistic regression analysis indicated that family characteristics and students’ schooling experiences were the strongest predictors of work-bound status. Work-bound youth were more likely to report greater family economic hardship, lower parental expectations for completing college, and more negative schooling experiences than college-bound rural youth.

El desarrollo es una experiencia de personas
Authors: Folloni Guiseppi 
Published: July 2019

El autor sostendrá que el factor principal para que se produzca el desarrollo con óptimos resultados es reconocer el valor de la experiencia, pero una experiencia "de personas". Así, planteará directrices para comprender qué es el desarrollo, además de cuáles son los factores que lo generan y lo hacen estable. De ese modo, demostrará que es necesario una experiencia directa de las personas, en su contexto familiar y social, de que algo puede cambiar, una experiencia que nace donde hay alguien que los acompaña, que vive con ellos la experiencia de cambio, situaciones y riesgos, oportunidades y dificultades, ayudando a comprender cuál es el camino.
Rosa de Lima, la Catalina de América
Authors: Benito Rodríguez José Antonio 
Published: July 2019

El presente artículo es la semblanza biográfica sobre santa Rosa de Lima y santa Catalina de Siena. Varios historiadores, gustaron de compararlas y ofrecernos "vidas paralelas". Sin embargo, la definición que nos dan las matemáticas de las líneas paralelas son "las líneas parecidas que por mucho que se prolonguen nunca se encuentran". En nuestro caso, Catalina y Rosa, salvo que vivieron tiempos distintos, son vidas paralelas en el lugar, vida y misión, pero que se encontraron en muchos aspectos; el más importante, su amor apasionado a Cristo, concretado en su Iglesia y en los pobres.
Símbolos distritales. Escudos de Lima Norte
Authors: Tácunan Bonifacio Santiago 
Published: July 2019

El presente artículo dará a conocer que, desde tiempos remotos, los pueblos, villas y ciudades se han identificado por medio de un escudo o blasón, en donde se resaltan las principales características del lugar, así como los más importantes atributos y potencialidades de la zona. De igual proceder han sido los líderes, las familias y las instituciones civiles y religiosas. Contemporáneamente, las corporaciones deportivas, las empresas, las naciones y estados independientes, también las utilizan. En ese sentido, el escudo cumple una triple función: es símbolo de identificación, emblema de distinción y marca de diferenciación.

Authors: Neira Reátegui Hilda 
Published: July 2019

En este artículo, se hablará, en gran parte, de los maestros que ensayan estrategias de aprendizaje con la finalidad de promover pensamientos críticos y reflexivos a través de la lectura, pues el pensamiento forma parte de la construcción de conocimientos en las diferentes esferas del saber. Es importante aprender a pensar frente a la tarea lectora, para aumentar nuestras nociones y conceptos sobre nosotros, la sociedad, la naturaleza, lo fantástico, lo artístico y lo espiritual. Finalmente, considerando este argumento, la autora intentará replantear la importancia de orientar y promover, mediante la lectura, las habilidades que contribuyan al fomento del pensamiento autónomo y multidireccional en el educando.
Una lectura carnavalesca del relato del Tohueyo y del ciclo de renovación de Quetzalcoatl, destronado por los dioses desestabilizadores Uitzilopuchtli y Titlacaoan
Authors: Malpartida Quispe Miguel Ángel 
Published: July 2019

El presente artículo hablará de la imagen del grotesco que se caracteriza por un constante movimiento hacia lo bajo material y corporal, inacabado y abierto al mundo, en desmedro de la imagen perfectamente cerrada y acabada de la proporción. El grotesco privilegia el desborde y la tensión corporal, los estados del cuerpo crítico y cambiante como el nacimiento, la agonía-muerte y el coito, instantes en que el cuerpo grotesco adquiere la categoría de cuerpo social y cuerpo cósmico, se enlaza al cuerpo del otro, da o entrega la energía poseída en un perfecto estado de dramatización del propio cuerpo.
Orígenes de la industria pesquera peruana
Authors: Puertas Porras María Elena , Maldonado Félix Héctor 
Published: July 2019

El artículo toma como punto de partida la revolución industrial que se inició en el siglo XVIII, la cual produjo un gran crecimiento demográfico que presionó a los sectores productores de alimentos. Esta presión llevó a que el sector pesquero emplease la red de enmalle pelágica desde la segunda mitad del siglo XIX, la misma que permitió incrementar la extracción de pescado. Gracias a ello, la demanda urbana impulsará la explotación del atún en el siglo XX.
El emotivismo libertario y sus secuelas
Authors: Bobadilla Rodríguez Francisco 
Published: July 2019

Este trabajo presenta una propuesta de comprensión de la crisis ética que anida detrás de una serie de reivindicaciones que parten de la libertad y buscan convertir ciertas apetencias en derechos. Existe un trasfondo antropológico que privilegia los deseos y niega la posibilidad de una naturaleza humana capaz de perfilar la andadura de las personas. Junto a los ya estudiados ídolos del poder, el dinero, la fama y el placer, nos parece que existe un nuevo ídolo, el emotivismo libertario. Este nuevo ídolo es el común denominador del actual divorcio unilateral, de los continuos intentos de despenalizar el aborto y de los proyectos alrededor de las uniones civiles. Se ha elegido una perspectiva filosófico-antropológica. De esta forma se ubica como el referente moderno por excelencia a Jean Jacques Rousseau y, aun cuando en el legalismo liberal el triunfo fue de Thomas Hobbes, en el vitalismo emotivista el gran triunfador póstumo es el primero: el buen salvaje redomado no soporta ni los límites de la ley ni los de la condición humana. Hecho el diagnóstico, la sugerencia es colocar, nuevamente, a la libertad en el conjunto de los radicales de la existencia humana. Una libertad que abrace la verdad del ser humano en toda su extensión y profundidad. La libertad huérfana de la verdad de la naturaleza humana no hace más que empobrecer la realidad humana.

Respon imun nonspesifik dan pertumbuhan udang vaname (Litopenaeus vannamei) yang diberi pakan yang ditambahkan nukleotida dengan lama pemberian berbeda
Authors: Manoppo Henky 
Published: July 2019

Abstract This study evaluated the effects of feeding protocol of nucleotide-supplemented diet on total hemocytes, PO activity and growth of whiteleg shrimp. Shrimp juveniles were reared in five 120-l glass aquaria at the density of 25 juveniles each. Shrimp pellet was supplemented with nucleotides mixture at 400 mg.kg-1 diet. Shrimps were fed three time a day at 3%/bw/d. Feeding protocol was 7 days nucleotides diet – 7 days basal diet alterably for 49 days. Total hemocyte count, PO activity, and growth were measured at the end of experiment. Research result showed that oral administration of nucleotides at seven days interval did not affect THC, PO activity, and growth of shrimp. But if the feed was administered successively for four weeks, supplementation of nucleotides would significantly enhance the nonspecific immune response and shrimp growth. Keywords: Litopenaeus vannamei, nucleotides, PO activity, total hemocyte count

Published: July 2019

The aim of this study was to know the applied technology and the production value of the aquaculture activities in the waters of Lake Tondano and to identify factors influencing aquaculture production in Tondano lake. Data collected consisted of primary and sekunder data. Primary data were collected by conducting a survey to fish-farmers as respondents around the lake Tondano. Operational aquaculture data were obtained by interviewing the fish farmers and by observation. Secondary data were collected from various institution such as Minahasa Fisheries Office , Office of Village Head and Fish-farmer Group Administrative Centre. Collected data were descriptively analyzed and presented in the form of tabulation and various model of diagram. Fluctuated data in aquacultural production value and the number of operated KJT during the periood of 2001 to 2014 was analysed by using linear regression and correlation. The aquacultral production value of the lake Tondano in 2014 was estimated only 1227,3 tons /year. The number of operated KJT only remained 1203 units. The production value decreased consistently from 2003 to 2014. Statistical analysis showed that during 2001-2014 there was a reduction about 1.236 ton every year in aquacultural production, and 607 units of operated KJT. There was a very strong correlation between time (year) and the the aquacultural production, and also between time (year) and the number of operated KJT. There were 3 important factors influencing the aquacultural production value of lake Tondano, which were: environmental, technical and economic factor. However, the primary factor was ‘economic’ factor. The ‘very high price’ of the fish formulated diet and the "very low price” of the produced fish were the main causes of the problem. The fish farmers could not afford the invesment and operational cost. Environmental degradation of Lake Tondano waters also significantly influenced the operation of aquacultural activities.

The aim of the present research was to evaluate the daily growth ratio, food conversion ratio and mortality of grouper (Epinephelus tauvina) and rabbit fish (Siganus canaliculatus) in floating net with polyculture system. This experiment was done at the coastal area of Tomini Bay in the North Sulawesi Province. The observations were done every two weeks for three months from August - November 2014. Twenty five groupers (62.41 grams in ABWo) and twenty five rabbit fish (52.2 grams in ABWo) were used for polyculture experiment, while fifty groupers (56.71 grams in ABWo) for monoculture. The results indicated that the daily individual growth of Epinephelus tauvina on polyculture was 1.29%, with food conversion ratio 6.1, while it on monoculture was 1,18%, with food conversion ratio 6.4. The daily individual growth of Siganus canaliculatus on polyculture was 0,8%, with food conversion ratio 3.8. Mortality for all species studied were 0%. The present research showed that the polyculture system was better than monoculture system. The future studies suggest that the polyculture system in the floating net may be developed and applied as a mariculture model in the North Sulawesi Province for prosperous life of fisherman. Keywords: Epinephelus tauvina, Siganus canaliculatus, polyculture system, floating net, prosperous life, fisherman.

Metasomatic Processes in the Lithospheric Mantle Beneath the No. 30 Kimberlite (Wafangdian Region, North China Craton)

Published: July 2019

AbstractThis paper presents the first major and trace element compositions of mantle-derived garnet xenocrysts from the diamondiferous No. 30 kimberlite pipe in the Wafangdian region, and these are used to constrain the nature and evolution of mantle metasomatism beneath the North China Craton (NCC). The major element data were acquired using an electron probe micro-analyzer and the trace element data were obtained using laser ablation inductively coupled plasma-mass spectrometry. Based on Ni-in-garnet thermometry, equilibrium temperatures of 1107–1365 °C were estimated for peridotitic garnets xenocrysts from the No. 30 kimberlite, with an average temperature of 1258 °C, and pressures calculated to be between 5.0 and 7.4 GPa. In a CaO versus Cr2O3 diagram, 52% of the garnets fall in the lherzolite field and 28% in the harzburgite field; a few of the garnets are eclogitic. Based on rare earth element patterns, the lherzolitic garnets are further divided into three groups. The compositional variations in garnet xenocrysts reflect two stages of metasomatism: early carbonatite melt/fluid metasomatism and late kimberlite metasomatism. The carbonatite melt/fluids are effective at introducing Sr and the light rare earth elements, but ineffective at transporting much Zr, Ti, Y, or heavy rare earth elements. The kimberlite metasomatic agent is highly effective at element transport, introducing, e.g., Ti, Zr, Y, and the rare earth elements. Combined with compositional data for garnet inclusions in diamonds and megacrysts from the Mengyin and Wafangdian kimberlites, we suggest that these signatures reflect a two-stage evolution of the sub-continental lithospheric mantle (SCLM) beneath the NCC: (1) early-stage carbonatite melt/fluid metasomatism resulting in metasomatic modification of the SCLM and likely associated with diamond crystallization; (2) late-stage kimberlite metasomatism related to the eruption of the 465 Ma kimberlite.
Nouvelles routes de la soie et endiguement économique et financier de la Chine par les États-Unis
Authors: Estachy Laurent 
Published: July 2019

L’initiative chinoise des nouvelles routes de la soie ne constitue pas une réminiscence sentimentale des voyages de Marco Polo, comme le soulignait en 2018 le ministre des Affaires étrangères allemand Sigmar Gabriel. Selon lui, cette initiative « se positionne comme une tentative pour établir un système cohérent, destiné in fine à façonner le monde dans le sens des intérêts chinois ». De façon plus générale, la réflexion doit être resituée dans le cadre d’une « Grande Stratégie » chinoise, de nature « mercantiliste », visant à remplacer les États-Unis comme puissance hégémonique mondiale. Telle est en tout cas la vision de la nouvelle administration américaine depuis novembre 2016 et l’élection du Président Donald Trump. Ainsi, à une « Grande » Stratégie chinoise répondrait désormais une « contre » stratégie américaine. Au-delà des routes de la soie, il s’agit en effet pour les États-Unis de contenir la montée en puissance de la Chine sous toutes ses formes ; industrielles, technologiques, commerciales, financières, diplomatiques et militaires.

Published: July 2019

La pratique d’une activité physique et sportive régulière est bénéfique pour la santé mais elle peut également occasionner un accident de sport dont la gravité peut être élevée. Les données enregistrées de 2004 à 2013 dans le cadre de l’Enquête permanente sur les accidents de la vie courante (EPAC), dans un service d’urgences d’un centre hospitalier de Haute-Savoie, ont été analysées afin de décrire les caractéristiques des accidents de sport dans une région particulièrement attractive pour les sports d’hiver et les sports aériens. Au total 43 505 accidents de sport ont été enregistrés : les sports d’équipe (30 %), les sports d’hiver (25 %) et le cyclisme (23 %) étaient les sports les plus représentés. Ces accidents concernaient davantage les hommes que les femmes (sex-ratio = 2,3), et la tranche d’âge 10-14 ans (21 % des accidentés). Tous sports confondus, les chutes ont été le mécanisme accidentel le plus fréquent. L’escalade, les sports d’hiver et les sports aériens sont les sports ayant entraîné le plus d’hospitalisations. Le risque d’hospitalisation suite à un accident de sport était plus élevé chez les hommes, quand l’âge augmentait et quand le lieu de résidence était situé hors de la Haute-Savoie. Des travaux complémentaires sont recommandés pour mesurer l’impact sur la survenue d’accident de l’utilisation de moyens de protection (casque, gants), du niveau de pratique et d’encadrement, ou de l’appartenance à un club sportif sur le risque d’hospitalisation.
Neurofibromatosis Type 1: A Population-Based Study
Authors: Bata Bashar M. , Hodge David O. , Mohney Brian G. 
Published: July 2019

Purpose:
To report the incidence, demographics, and clinical manifestations of neurofibromatosis type 1 among a population-based cohort of patients.

Methods:
The medical records of all patients diagnosed as having neurofibromatosis type 1 while residing in Olmsted County, Minnesota, from January 1, 1980, through December 31, 2009, were retrospectively reviewed.

Results:
Fifty patients were diagnosed as having neurofibromatosis type 1 during the 30-year period, yielding an incidence of 1.2 per 100,000 individuals. The mean age at diagnosis was 11.7 years (95% confidence interval [CI]: 0.2 to 47) and 26 (52%) were males. Twenty-eight patients were new mutations, yielding a de novo mutation rate of 56%. During a mean follow-up of 9.8 years (range: 3 weeks to 32 years), café-au-lait macules were diagnosed in 49 individuals (98%), neurofibromas in 26 (52%), and skeletal anomalies in 14 (28%). Three (5.9%) individuals were diagnosed as having glioma of the central nervous system (95% CI: 1.2 to 9.7%) at a mean age of 13 years (range: 5 to 26 years), including 1 patient with optic nerve glioma diagnosed at the age of 26 years. Only 1 (2%) patient was diagnosed as having malignant nerve sheath tumor.

Conclusions:
Although the prevalence and de novo mutation rate of neurofibromatosis type 1 in this population-based study were similar to prior reports, the occurrence of optic nerve gliomas was much lower.

Evaluation of a Free Public Smartphone Application to Detect Leukocoria in High-Risk Children Aged 1 to 6 Years
Authors: Vagge Aldo , Wangtiraumnuay Nutsuchar , Pellegrini Marco , Scotto Riccardo , Iester Michele , Traverso Carlo Enrico 
Published: July 2019

Purpose:
To determine whether a white-eye detector smartphone application (app) can be used as a screening tool to detect early signs of leukocoria in a clinical practice.

Methods:
A prospective, single-visit study of children aged 1 to 6 years presenting for a complete pediatric ophthalmologic examination was conducted. All children who met the enrollment criteria were screened by an orthoptist with the CRADLE (Computer Assisted Detector of Leukocoria) smartphone app for an iPhone operating system (iOS) (iPhone 7; Apple, Cupertino, CA). Cycloplegic retinoscopy and fundus examination were performed 30 minutes after one to two drops of a pediatric combination drop, comprising tropicamide 1% and phenylephrine 2.5%, were instilled. A comparison between the two methods yielded sensitivity, specificity, and negative likelihood ratio values.

Results:
A total of 244 eyes of 122 children were included in the study. Nine eyes of 244 (3.6%) had leukocoria evaluable by penlight caused by amblyogenic cataract, 1 (0.4%) patient had retinopathy of prematurity stage 5, and 3 (1.2%) patients had retinoblastoma. The sensitivity of the white-eye detector app was 15.38% (95% confidence interval [CI]: 1.92% to 45.45%), the specificity was 100% (95% CI: 98.48% to 100.00%), and the negative likelihood ratio was 0.85 (95% CI: 0.67 to 1.07).

Conclusions:
A smartphone photoscreening app able to detect leukocoria may provide valuable support for children's parents. However, it cannot be considered an alternative to the ophthalmoscope for children.
