Authors: Sulistiyani Endang , Ali Achmad Holil Noor , Astuti Hanim Maria
Published: September 2020

Information Systems Department has used fingerprints as a student attendance system. But its implementation is briefly, because there are still technical and non-technical problems in the system. Unfortunately, at this time, the fingerprint is only left installed in each classroom and the manual attendance system is reused. It can be seen that the unsuccessful project management is caused by problems in changing from the manual system to the fingerprint system. Based on the ploblems, Information Systems Department of ITS requires change management strategies to implement this system. The planning of change management strategy is initiated by analyzing the gap between the business processes of manual attendance system and of the fingerprint-based attendance system. The goal of this gap analysis is to identify the changes and the impacts which then let to an identification to the solution. The solution will be an input for the development of change management strategy using the perspectives of Awareness, Desire, Knowledge, Ability, Reinforcement (ADKAR) model. The strategy is then mapped according to Prosci’s state of change. The result from this research is a change management roadmap of the fingerprint system’s implementation. This roadmap contains three states of change, which covering current, transition, and future.

Authors: Fadil Abdullah
Published: September 2020

Arsitektur data center di dalam cloud computing merupakan lingkungan yang heterogen dan terdistribusi, tersusun atas gugusan jaringan physical machine (PM) atau server dengan berbagai kapasitas sumber daya komputasi yang berbeda-beda di dalam PMnya. Kondisi permintaan (demand) dan ketersediaan (supply) pada layanan cloud yang fluktuatif tersebut membuat data center cloud harus dibuat elastis. Virtual Machine (VM) merupakan representasi dari ketersediaan sumber daya komputasi dinamis yang dapat dialokasikan dan direlokasikan sesuai dengan permintaan. VM yang berada di dalam data center cloud dapat dipindahkan dari satu PM ke PM lainnya menggunakan migrasi VM secara langsung (live VM migration) ataupun tidak langsung (off-line VM migration). lingkungan cloud computing yang dinamis dan terdistribusi mengharuskan strategi pengambilan keputusan di dalam konsolidasi VM harus dibuat sedinamis mungkin atau bahkan adaptif dengan mempertimbangkan heterogenitas sumber daya virtual sesuai dengan layanan cloud computing yang disajikan. Sehingga, dalam penelitian ini diusulkan efisiensi energi sekaligus menjaga kinerja layanan cloud computing melalui penyeimbangan beban kerja dengan teknik migrasi VM yang terdapat pada prosedur konsolidasi VM dinamis. Strategi pengambilan keputusan pada prosedur konsolidasi virtual machine dinamis yang diusulkan, dapat meningkatkan kinerja layanan cloud computing sekaligus beban kerja physical machine menjadi seimbang karena keputusan pemilihan VM dan penempatan VM pada physical machine dipilih secara optimal melalui MADM. Konsumsi energi dari physical machine juga dapat di hemat dengan mematikannya karena statusnya idle.

Published: September 2020

The libraries’ web-outposts open up new opportunities, enable libraries to interact efficiently with their users and to promote their information products in the virtual space. The systematic assessment is integral to high performance of libraries’ web-divisions. The author explores the intensity of applying evaluation methods to the libraries’ web-sites. She examines the current state and popular trends in libraries’ representation in the virtual space using the relevant methods of web-analytics. The findings of the 2019 survey “Modern trends in the development of library resources in the web space”, comprising 387 Russian and foreign libraries of various organizational and legal status, are discussed. Particular attention is paid to the presence of libraries in the web space and resource management using web-analytic instruments. Based on her research findings, the author concludes that the major accomplishment for the libraries today is the very fact of their presence in the web space in the form of official websites and accounts in social media. Though the respondents confirmed that they used web-based analytical tools to evaluate their own web-based representation, the survey demonstrates that just a small part of the analytical tools potentiality is actually used.

Türkçe Öğretmen Adaylarının Sezgisel Yolla Dil Bilgisi Öğretimine Yönelik Hazır Bulunuşlukları
Authors: Türkel Ali , Dundar Ebru
Published: September 2020

Bu çalışmada 3. ve 4. sınıf Türkçe öğretmen adaylarının dil bilgisi öğretiminde sezgisel yolla öğretim yapmaya yönelik hazır bulunuşlukları saptanmaya çalışılmış, bu amaçla Dokuz Eylül Üniversitesinde 3. ve 4. sınıfta okuyan 120 Türkçe öğretmen adayıyla görüşülmüştür. Veriler nitel veri analizi yöntemiyle değerlendirilmiş, veri toplama aracı olarak araştırmacılarca geliştirilen “Yarı Yapılandırılmış Görüşme Formu” kullanılmıştır. Toplanan verilerde adayların büyük bölümünün (%69) sezgisel yolla dil bilgisi öğretiminin kendilerine bilgi olarak öğretildiğini düşündüğü görülmüştür. Ancak adaylar uygulamaların nasıl gerçekleştirilebileceğinin örneklendirilmediğini, kuramsal bilgileri uygulamada yetersiz hissettiklerini belirtmiştir. Araştırma sonuçlarına göre adayların sezgisel yolla dil bilgisi öğretiminde yeterli kuramsal bilgiye sahip oldukları; ancak bu bilgiyi öğretebilmede kendilerini yetersiz hissettikleri söylenebilir. Sonuç olarak Türkçe öğretmenliği lisans programına uygulamayı da kapsayan sezgisel yolla dil bilgisi öğretimini içeren bir derse gereksinim olduğu görülmektedir. Türkçe öğretmenliği programlarında dinleme, konuşma, okuma, yazma becerilerinin öğretimine yönelik dersler vardır. Oysa ortaokul Türkçe ders programlarında önemli payı olan dil bilgisinin öğretimine yönelik bir ders bulunmamaktadır. Bu bir eksiklik olarak değerlendirilebilir.

Published: September 2020

Sözel problemlerde karmaşıklık yaratan durumlardan birisi problemlerdeki anahtar sözcüklerin problemin çözümü için gerekli işlemle tutarlı olup olmadığıdır. Bu araştırmada, ilkokul öğrencilerinin işlemle tutarlı ve tutarsız anahtar sözcükler içeren sözel problemlerdeki performanslarının Türkçe ve matematik dersi akademik başarılarına göre nasıl değiştiğinin ve problem çözme performansı üzerinde anahtar sözcüklerin rolünün incelenmesi amaçlanmıştır. Araştırmanın nicel aşamasına, uygun örnekleme yöntemiyle belirlenen ve ilkokul 3. ve 4. sınıfta öğrenim görmekte olan 100 öğrenci katılmıştır. Araştırmanın nitel aşamasında yarı yapılandırılmış görüşmeler yapılmış olup katılımcılar maksimum çeşitlilik örneklemesi yoluyla belirlenmiştir. Araştırma sonucunda, işlemle tutarlı anahtar sözcükler içeren problemlerde öğrenciler daha yüksek performans gösterirken, işlemle tutarsız anahtar sözcükler içeren sözel problemlerde daha düşük performans göstermiştir.  Öğrencilere işlem seçimlerinin gerekçeleri sorulduğunda, büyük bir çoğunluğu işlemle tutarlı ve tutarsız anahtar sözcüklere vurgu yapmıştır. İşlemle tutarsız anahtar sözcüklerin yer aldığı problemler, genellikle düşük ve orta başarı grubundaki öğrencilerin hatalı işlem tercihinde bulunmasına neden olmuştur. Özellikle ilkokul döneminde öğrencilerin okuduğunu anlama becerilerinin geliştirilmesi ve sözel problemlerin anlamsal-dilsel özellikleri ile nasıl başa çıkılacağının öğretilmesi öğrencilerin ilerleyen yaşlardaki performanslarının olumlu yönde gelişmesini destekleyebilir.

Authors: Berrubé Alban , Leduc Nicolas , Hidalgo Jorge , Aubry Simon
Published: September 2020

La generación de superficies tridimensionales basadas en pliegues curvos es un proceso eficiente en cuanto a tiempo y costo, que evita el uso de moldes. En este trabajo demostramos que utilizando el comportamiento mecánico de los materiales y la cinemática de plegado podemos ampliar las posibilidades de esta técnica de fabricación. El diseño paramétrico se combina con análisis estructurales simplificados de modelos de elementos finitos para desarrollar un proceso de búsqueda de formas robustas y optimizar las geometrías. Para validar este método simplificado se utiliza un modelo de elementos finitos no lineal que simula la deformación paso a paso del panel de plano a deformado. Finalmente, se construye una serie de prototipos a escala 1:4 para verificar la viabilidad de fabricación en condiciones reales y el aspecto resultante del panel acabado.

Published: September 2020

Como en algunos otros idiomas, y a diferencia del inglés, el término Roofless (sin techo) se utiliza coloquialmente para referirse a las personas sin casa y sin recursos en Castellano; este termino enfatiza la importancia de estar a cubierto, de tener un techo que te proteja, y es muy indicativo de hacia dónde deben dirigirse los esfuerzos de los arquitectos e ingenieros interesados en las estructuras espaciales o de cascaron. En resumen, debemos buscar formas más asequibles de construir techos.Resulta que las cáscaras de hormigón cayeron en desuso debido a los cambios en las modas estéticas, los altos costes involucrados en las estructuras auxiliares necesarias para construirlas, y la impracticabilidad de los espacios generados.La clave para revertir estos tres aspectos negativos está en el encofrado.Este trabajo presenta la eficacia del uso de estructuras realizadas con cañas (Arundo Donax o Bambú) como encofrado económico y ecológico para hacer de los Cascarones estructurales un sistema constructivo más asequible y funcional.

En este artículo se revisita la clásica cercha espacial de doble pared reemplazando las diagonales por módulos poliédricos curvos de paredes delgadas. Las mejoras esperadas son tanto tecnológicas como mecánicas. Los nodos complejos de 8 ramas se dividen en una conexión de dos miembros continuos superpuestos y una conexión lineal entre las barras y los bordes del poliedro. La curvatura en las caras y bordes de los módulos introduce resistencia por forma y estabiliza los miembros frente al pandeo. La optimización global de la estructura se realiza mediante un proceso de búsqueda de forma basado en la parametrización individual de los módulos.Finalmente, se lleva a cabo una validación experimental mediante la fabricación y prueba de un prototipo a escala real (de 6 x 6 m aproximadamente).
The Case for Digital Activism: Refuting the Fallacies of Slacktivism
Authors: Madison Nora , Klang Mathias
Published: September 2020

This paper argues for the importance and value of digital activism. We first outline the arguments against digitally mediated activism and then address the counter-arguments against its derogatory criticisms. The low threshold for participating in technologically mediated activism seems to irk its detractors. Indeed, the term used to downplay digital activism is slacktivism, a portmanteau of slacker and activism. The use of slacker is intended to stress the inaction, low effort, and laziness of the person and thereby question their dedication to the cause. In this work we argue that digital activism plays a vital role in the arsenal of the activist and needs to be studied on its own terms in order to be more fully understood.

Hybridization and its relevance is a hot topic in ecology and evolutionary biology. Interspecific gene flow may play a key role in species adaptation to environmental change, as well as in the survival of endangered populations. Despite the fact that hybridization is quite common in plants, many hybridizing species, such as Quercus spp., maintain their integrity, while precise determination of genomic boundaries between species remains elusive. Novel high throughput sequencing techniques have opened up new perspectives in the comparative analysis of genomes and in the study of historical and current interspecific gene flow. In this work, we applied ddRADseq technique and developed an ad hoc bioinformatics pipeline for the study of ongoing hybridization between two relevant Mediterranean oaks, Q. ilex and Q. suber. We adopted a local scale approach, analyzing adult hybrids (sensu lato) identified in a mixed stand and their open-pollinated progenies. We have identified up to 9,251 markers across the genome and have estimated individual introgression levels in adults and seedlings. Estimated contribution of Q. suber to the genome is higher, on average, in hybrid progenies than in hybrid adults, suggesting preferential backcrossing with this parental species, maybe followed by selection during juvenile stages against individuals with higher Q. suber genomic contribution. Most discriminating markers seem to be scattered throughout the genome, suggesting that a large number of small genomic regions underlie boundaries between these species. In adult hybrids 273 markers (3%) showed allelic frequencies very similar to one of the parental species, and very different from the other; these loci could be relevant for understanding the hybridization process and the occurrence of adaptive introgression. Candidate marker databases developed in this study constitute a valuable resource to design large scale re-sequencing experiments in Mediterranean sclerophyllous oak species and could provide insight into species boundaries and adaptive introgression between Q. suber and Q. ilex.

La globalización y el dinamismo de los mercados presionan a las empresas a implementar diversas estrategias para defender su posicionamiento. La innovación sobresale como respuesta estratégica de las empresas para adaptarse a los cambios. Este trabajo se guía por el objetivo de identificar los tipos de innovación que las empresas están utilizando como estrategias de adaptación al dinamismo de los mercados. Se emplea un enfoque cualitativo mediante la aplicación de los métodos teóricos histórico-lógico y analítico-sintético para la interpretación de la literatura relevante. Se utilizan como fuentes de información 20 publicaciones científicas que cubren estudios de casos de empresas exportadoras que han aplicado prácticas organizacionales, a partir de las cuales se asocia a un tipo de innovación. Para el caso de Ecuador el análisis se centra en tres sectores productivos, tomando como referencia la representatividad de los productos de exportación. Entre los principales hallazgos se destaca que las empresas aplican la innovación abierta asociada a los procesos de certificación que requieren referentes externos de buenas prácticas, cooperación y transferencia de información. Finalmente se concluye que las empresas emplean mayoritariamente la innovación de tipo incremental, seguida de la innovación abierta y la innovación radical para responder a los cambios del entorno, mejorar el aprendizaje y aprovechar las oportunidades de los mercados globales.

El tipo de investigación fue participativa, enfoque cualitativo y un diseño  de estudio de casos. Se recogieron las entrevistas de un comisario policial de distrito, de un experto en temas de asuntos policiales, de un empresario víctima de hechos delictivos y de un ex miembro  dirigencial  del Comité de Seguridad ciudadana del Distrito.  Los principales hallazgos encontrados  fueron: falta de   compromiso y responsabilidad   de los  representantes del Comité Local de Seguridad Ciudadana, alto índice de inseguridad en la zona, robos y asaltos que afectan  los negocios, falta de efectivos policiales y serenos,  alta rotación de comisarios, demora en  la  capacidad de respuesta de la policía ante la denuncia de un hecho delictivo e  inmigración  descontrolada. Las  principales conclusiones fueron: nivel de eficacia de los planes  de seguridad ciudadana  solo alcanzaron un nivel valorativo  medio de  (58.34%), inadecuado sistema de control del plan local  de seguridad ciudadana e incumplimiento de las categorías apriorísticas contrastadas.
La Academia de Diseño en el escenario de la Innovación Tecnológica
Authors: Gómez-Vera Laura Teresa
Published: September 2020

En este artículo se expone, desde una perspectiva teórica, la gestión integral del diseño para hacer frente a la práctica pedagógica por objetivos e incitar la innovación tecnológica en el desarrollo de proyectos que deriven en bienes y servicios innovadores. Particularmente, en los escenarios académicos mexicanos es conveniente trabajar en torno a las funciones del “Modelo de Gestión de la Tecnología” que planteó, desde el 2012, la Fundación del Premio Nacional de Tecnología e Innovación. Se recurrió al análisis cualitativo de explicaciones teóricas con base en los principios metodológicos descriptivos para exponer la analogía entre la organización de la academia, la intervención pedagógica y la deducción cognitiva en el ámbito de la “planeación, vigilancia, habilitación, protección e implantación tecnológica” (FPNTI, 2016). La interrelación pedagógica que se provoca con la dirección integral de proyectos de diseño es el resultado que se espera en la profesionalización de este campo de estudio.

This work investigated the genetic diversity of 134 Castanea sativa Mill. accessions present in the Italian region of Emilia-Romagna. Samples were taken from three collection fields (Granaglione, Zocca and Paloneta) in the Tuscan-Emilian Apennines. The accessions were analyzed by using 16 microsatellite markers (SSR). Genetic distances among accessions, calculated through the DICE coefficient, were used to construct an UPGMA cluster analysis. One major genotype (named “Marroni”) was identified across the three investigated collection fields; this variety corresponds to a sweet chestnut cultivar that has been propagated and widely diffused in the Emilia-Romagna region. Other genotypes were represented by different varieties of Italian chestnuts. The results of this study will be used to define and share guidelines for the characterization and varietal certification of the chestnut varieties in the Emilia-Romagna region.

Overuse of mineral fertilizer has become common at the North China Plain. Simultaneously, more organic manure resources are available for smallholder farmers. In order to increase the use of organic manure and reduce mineral fertilizer applications, a 10-year fertilization experiment with maize took place between 2008 and 2017. We assessed the long-term effects of cattle manure (CM) application and a complete nutrient substitution with mineral fertilizer (MF) at four application levels (3, 6, 9 and 12 t ha−1 CM) on yield, macronutrients (N, P and K) use efficiencies and soil conditions. Results showed that maize yields from CM and MF treatments differed across time and were significantly different in the first year of the experiment to no significant differences with increasing experimental time. In addition, increased MF levels did not result in increased maize yields; this response was different with CM applications. The highest 10-year maize average yield was 7.7 t ha−1 obtained with 9 t ha−1 of CM. Our results also showed that at the lowest application level (3 t ha−1 CM), the partial factor productivity (PFP) and the agronomic efficiency (AE) of all macronutrients were significantly higher with MF than with CM applications. Nevertheless, these differences narrowed with increased fertilizer input levels. The MF and CM recovery efficiency (RE) of N, P and K performed differently. Generally, MF exhibited significantly higher N-RE than CM treatments. CM treatments had significantly higher P-RE, but no K-RE differences were found between CM and MF. Soil available N, P and K significantly increased when fertilizer levels raised. MF treatments exhibited similar levels of soil available N, but lower soil available P and K compared with CM treatments.

In urban areas, land use usually increases soil degradation. However, there are areas occupied by agriculture and woodlands with an essential role in provisioning food and other services such as water and climate regulation. The objective of this work was to assess the effect of long-term land use and soil management practices on peri-urban soils in Zagreb (Croatia). Samples were collected at depth 0–10 cm within intensively tilled cropland (CROP) and vineyard (VINE), traditional grass-covered orchard (ORCH), and forest (FOR). The results showed that bulk density was significantly higher in VINE and CROP than in ORCH and FOR. The opposite dynamic was observed in water-holding capacity, air-filled porosity, aggregate stability, organic matter, and soil organic matter stocks (SOCS). Soil water infiltration was higher in FOR plot compared to the other plots. Overall, land-use change had a substantial impact on soil properties and SOCS, especially in CROP and VINE soils. Tillage, pesticides, and fertilizer applications were presumably the reasons for altered soil quality properties. Intensively used areas (VINE and CROPS) may reduce soil ecosystems services such as the capacity for flood retention and C sequestration.
