La Plazuela de los Desamparados y su entorno urbano-monumental: Valoración histórica de la construcción de un lugar
Authors: Ravines Casas Jonathan
Published: December 2018

Hace poco más de 70 años, en lo que hoy se conoce como el traspatio de Palacio de Gobierno, existió una plazuela cuya importancia e historia datan de las primeras décadas de la fundación española: la Plazuela de los Desamparados. Este espacio público fue famoso por la intensa dinámica urbana que en él tenía lugar. La plazuela era el primer espacio de recibo de los limeños que venían del barrio de “abajo del puente”, así como lugar de congregación de la orden jesuita, quienes solían impartir clases en la escuela ubicada al lado de la Iglesia de los Desamparados. Configuraban la plazuela la Iglesia de Nuestra Señora de los Desamparados y al Arco del Puente de Piedra, elementos de gran valor arquitectónico y patrimonial que sucumbieron junto con la plazuela por los avatares del destino y de la modernidad. Este artículo pretende hacer una pequeña remembranza sobre la desaparecida plazuela, y una reflexión sobre el estado actual de este espacio y su posible recuperación para la ciudad.
La recuperación participativa de la historia y la memoria para el uso social del patrimonio huarochirano: El caso del ex Centro Educativo N°443
Authors: Pajuelo Montes Rosario
Published: December 2018

La recuperación participativa de la historia y la memoria vinculada al ex Centro Educativo N°443, remite a la investigación social crítica y a la práctica dialógica para la construcción del conocimiento sobre la base de los saberes, lenguajes y formas de comprensión de la población local. También lleva a incluir las perspectivas de las ciencias sociales, arte, y sabidurías ancestrales y populares. En la recuperación participativa, las voces locales fueron determinantes para la elección del objeto de estudio; para el reconocimiento de los aspectos económicos, políticos, sociales, culturales y ambientales; y para la identificación de los intereses, necesidades y expectativas que luego definirían el uso social de la edificación. El 443 visibiliza los hechos, conocimientos y experiencias del pasado, los cuales fueron construidos y enriquecidos por los lazos comunitarios. También constituye una expresión material y un referente territorial de las vivencias que aún persisten y mantienen viva la tradición, memoria e identidad para conservar el patrimonio y mejorar la calidad de vida de los pobladores de Huarochirí, Lima.

Published: December 2018

In 2050, world population will reach a total of 9 billion inhabitants and their food demand have to be satisfied. Durum wheat (Triticum turgidum L. var. durum) is one of the most important food crop and its consumption is increasing worldwide. Productivity growth in agriculture and profitable returns are strongly influenced by investment in research and development, where Precision Agriculture (PA) represents an innovative way to manage farms by introducing the Information and Communication Technology (ICT) into the production process. It is known that farms activities produce large amounts of data. Today ICT allows, with electronic and software systems, to collect and transfer automatically these data, thus increasing yields and profits. In this direction significant data are processed from agricultural production, and retrieved to extract useful information important to increase the knowledge base. Data from multiple data sources can be processed by a Data Fusion (DF) approach able to combine multiple data sources into an unique database system. Raw data are transformed into useful information, thus DF improves pattern recognition, analysis of growth factors, and relationship between crops and environments. Data Fusion is synonym of Data Integration, Sensor Fusion, and Image Fusion. By means of Data Mining (DM) it is possible to extract useful information from data of the production processes thus providing new outputs concerning product quality and product “health status”. The following literature take into account the DF and DM techniques applied to Precision Agriculture (PA) and to cultivation inputs (water, nitrogen, etc.) management.  We report also last advances of DF and DM in modern agriculture and in precision durum wheat production.
ENDÜSTRİYEL AMAÇLI YENİ BİR ANALİTİK RİSK TANIMLAMA YÖNTEMİ ÖNERİSİ
Authors: CAN Gülin Feryal , CAN Özgün
Published: December 2018

Risk analizi çalışmalarının en önemli adımlarından
birisi, incelenen sistemlerde hangi tür risklerin ortaya çıkabileceğinin
belirlenmesidir. İncelenen sistemlerin uzun süredir çalışmakta olduğu, bu
süreçte meydana gelen arıza ya da tehlike yaratan durumların gözlemlenerek
kayıt altına alındığı, tecrübeli kullanıcıların ve uzman risk analizcilerinin
geçmiş deneyimlerinden faydalanılabildiği durumlarda potansiyel riskler büyük
ölçüde belirlenebilmektedir. Ancak yeni tasarlanan, yeni kullanılmaya başlanan
ya da geçmiş kullanım sürecine ilişkin yeterli bilgi elde edilemeyen
sistemlerde oluşabilecek risk türleriyle ilgili belirsizlikler oluşmaktadır. Bu
çalışma, oluşabilecek riskler hakkında yeterli bilgi ve tecrübenin olmadığı
durumlarda, olası risklerin tanımlanabilmesi için analitik bir yöntem
geliştirilmesini amaçlamaktadır. Bu kapsamda ilk olarak; incelenecek sisteme
çevre sistemlerden gelebilecek mekanik, elektriksel, kimyasal, ısıl, vd.
etkiler ve özellikleri tespit edilmekte, bir sonraki adımda çevre sistemler ile
oluşturduğu ara yüzler ve bu ara yüzlere ait özellikler, daha sonra da sistemin
içinde bulunduğu mekanik, elektriksel, kimyasal, ısıl, vd. durumlar
belirlenmektedir. Son olarak sistemin maruz kaldığı etkiler, ara yüz
özellikleri ve içinde bulunduğu durum arasındaki etkileşimler bir risk
belirleme matrisi üzerinde eşleştirilerek meydana gelebilecek riskler
tanımlanmaktadır. Önerilen yaklaşım, sistemin çalıştığı proses adımları için
tüm olasılıkları dikkate alarak sistematik bir risk belirleme yöntemi
oluşturmayı amaçlamakta ancak geçmiş dönemler için yapılan araştırma
çalışmalarından, iş güvenliği uzmanlık bilgisi ve tecrübesinden yararlanma
gerekliliğini ortadan kaldırmamakta, tasarımcı ya da kullanıcıya, risklerin
belirlenmesi için destek sağlamaktadır. Çalışmada önerilen yaklaşım örnek
olarak bir eksenli bir robotun, tehlikeli kimyasal içeren plastik bidonları bir
taşıma hattından diğerine aktarma prosesine uygulanmıştır.

Published: December 2018

Asansör montaj işlemleri dar alanda çalışma, eğilme, çömelme, uzanma ve
baş üstü çalışma gibi birçok ergonomik risk faktörü içermektedir. Bu alanda
çalışanların çalışma duruşlarını ve ergonomik etkilenme düzeylerini belirleyen
bir çalışma bulunmamaktadır. Bu araştırmada asansör montaj işlemlerinin
ergonomik yönden değerlendirilmesi amaçlanmıştır. Çalışma İzmir iline bağlı 8 ilçede
20 şantiyede gerçekleştirilmiştir. Gözlem ve görüntü kaydı ile elde edilen
veriler taşıma işleri için MAC, statik işler için RULA ve REBA yöntemleri
kullanılarak değerlendirilmiştir. Sonuçlar taşıma işlemlerinde işçilerin
gereğinden fazla zorlandığını, 30 kilogramın üstündeki yükleri tek başlarına
taşımak zorunda kaldıklarını ortaya koymuştur. Çalışma duruşları açısından
yapılan değerlendirmelerde 50 farklı montaj işleminin 28 inin Yüksek-Çok Yüksek
risk grubunda yer aldığı belirlenmiştir. Mesleki eğitim düzeyinin düşük olması,
çalışmaların çok küçük gruplarla gerçekleştirilmesi, iş organizasyonunun
yetersiz olması temel sorunlar olarak ortaya çıkmıştır.

Published: December 2018

BACKGROUND

Patients with ST-segment elevation myocardial infarction (STEMI) experience major adverse cardiac events (MACEs) following primary percutaneous coronary intervention (PCI). Although the relationship between time to treatment (eg, door-to-balloon time, symptom onset-to-balloon time, and symptom onset-to-door time) and 1-month all-cause mortality was assessed previously, its relationship with in-hospital MACEs and the effect of some clinical characteristics on this relationship were not considered. Furthermore, previous studies that were conducted in developed countries with a different quality of care cannot be applied in Iran, as Iran is a developing country and the studies were not performed according to the 24/7 primary PCI service registry.

OBJECTIVE

The objective of this study protocol is to determine the relationship between time to treatment and in-hospital MACEs.

METHODS

This cross-sectional study will take place at the Tehran Heart Center (THC), which is affiliated with Tehran University of Medical Sciences (TUMS) in Tehran, Iran. Data related to patients with STEMI, who underwent primary PCI between March 2015 and March 2019, that have been prospectively recorded in the THC’s 24/7 primary PCI service registry will be analyzed. The study outcome is the occurrence of in-hospital MACEs. Data analysis will be conducted using SPSS for Windows, version 16.0 (SPSS Inc). We will perform chi-square tests, independent-samples t tests, or the Mann-Whitney U test, as well as univariate and multivariate binary logistic regression with a significance level of less than .05 and 95% CI for odds ratios.

RESULTS

From March 2015 to September 2017, 1586 patients were included in the THC service registry, consecutively. We will conduct a retrospective analysis of this registry on patient entries between March 2015 and March 2019 and data will be analyzed and published by the end of 2019.

CONCLUSIONS

To our knowledge, this is the first observational study based on the 24/7 primary PCI service registry in Iran. The findings of this study may reveal current problems regarding time to treatment in STEMI management in the THC. Results from this study may help determine appropriate preventive strategies that need to be applied in order to reduce time-to-treatment delays and improve patients’ outcomes following primary PCI in the setting of STEMI at the THC and similar clinical centers.

Authors: Su Wei-San , Hsu Chao-Chun , Huang Cheng-Hung , Chang Lan-Fang
Published: December 2018

We focused in this study on the linear relationships among satisfaction with setting attributes, revisit intention, and place attachment, and also investigated the role of place attachment as a mediator in the relationship between setting attributes and revisit behavioral intention.
Sports tourists (N = 294) who participated in triathlon events were recruited using convenience sampling and completed questionnaires. The empirical results revealed that satisfaction with setting attributes positively affected place attachment, which positively affected revisit intention.
Satisfaction with setting attributes exerted a positive influence on revisit intention. Place attachment was found to be a significant mediator in the relationship between satisfaction with setting attributes and revisit intention. Our results can be used as a basis for improving and advancing
sports tourism strategies to create a competitive advantage.
IMPACT OF DRUG EXPOSURE DEFINITIONS ON OBSERVED ASSOCIATIONS IN PHARMACOEPIDEMIOLOGY RESEARCH
Authors: Eskin M , Simpson SH , Eurich DT
Published: December 2018

BACKGROUND - A variety of methods used to define exposure in pharmacoepidemiologic studies. Although each method has known biases, the relative effect of these biases on an observed association has not been fully examined.

OBJECTIVE - To explore the influence of different exposure definitions on estimates, using the association between metformin and all-cause mortality as a proto-typical model.

METHODS - New users of oral anti-hyperglycemic drugs were identified using administrative health databases from Alberta, Canada between 1998 and 2010. Drug exposure was described using definitions that are commonly used in observational studies. All analyses included the same covariates of age, gender, and a comorbidity score, and subjects not exposed to metformin served as the reference group. The measure of association was assessed using a Cox Proportional Hazards model for cohort studies and conditional logistic regression for case-control studies.

RESULTS – We identified 64,293 new oral anti-hyperglycemic drugs users; mean age 68.9 years, 33,131 (52%) males, and 24,745 (39%) deaths during a mean follow-up of 6 years.  In adjusted models, the association between metformin and mortality ranged from 0.23 (95% CI 0.22-0.25) to 0.92 (95% CI 0.88-0.95) reduction. Most metformin exposure definitions, however, provided estimates in the 0.6-0.8 reduction range, aligning with the results of previous observational studies.

CONCLUSIONS – The variety of exposure definitions tested in this analysis produced a wide range of associations between metformin and mortality risk. Therefore, pharmacoepidemiological studies should include sensitivity analyses using at least two exposure definitions with complementary risks of bias to improve the validity of study results.

Si bien el nuevo presidente de Colombia, 2018-2022, se ha comprometido a no romper el acuerdo de Paz con las FARC, también ha sido enfático en su interés por modificarlo, lo que ha significado un año muy incierto para quienes estamos comprometidos con la defensa de los Derechos Humanos y la construcción de un país en Paz.
Instrumentos de Justicia Transicional implementados en la desmovilización de grupos armados en Colombia
Authors: MORA MÉNDEZ BLANCA LUCÍA
Published: December 2018

A través del análisis de conceptos básicos sobre justicia transicional, se examinará en este escrito la desmovilización del Movimiento 19 de abril (en adelante M-19) y las Auto Defensas Unidas de Colombia (en adelante AUC), haciendo una revisión de las medidas implementadas, sus resultados y aportes, tanto en la conceptualización jurídica, como en la incorporación de estándares internacionales que buscan la promoción y defensa de los derechos humanos, así como la reducción y/o eliminación de los efectos del conflicto armado. 

Se buscará establecer si las medidas aplicadas en los procesos de desmovilización en Colombia se pueden considerar como instrumentos de justicia transicional teniendo en cuenta su eficacia, porcentaje de miembros realmente desmovilizados, medidas de carácter penal, judicial y administrativo aplicadas a los miembros de esos grupos, y finalmente, el reconocimiento de las víctimas como figuras de relevante importancia; la evolución del reconocimiento de sus derechos a la verdad, justicia, reparación y no repetición.
Memoria de las víctimas en el Acuerdo de Paz del gobierno colombiano y las Farc – Ep
Authors: DELGADO LASSO SUSANA
Published: December 2018

El artículo tiene como propósito analizar la memoria como espacio de reconstrucción del pasado, orientado hacia la reivindicación de las víctimas; y como su derecho legítimo, relacionado directamente con el ejercicio y goce del derecho a la verdad, de manera que permita superar los escenarios de violencia y violación de las normas internacionales de derechos humanos. Para ello, el acuerdo de paz y su implementación deben garantizar espacios para la reconstrucción de la memoria histórica del país, considerando los daños y el sufrimiento padecido por millones de víctimas que ha dejado el conflicto armado en Colombia. En esa medida se plantea la memoria como una estrategia que permite la conciliación y la convivencia en procesos transicionales que buscan la paz. En ese orden de ideas, se expondrá la evolución y desarrollo jurídico de la memoria en el campo internacional y dentro del panorama colombiano con relación al acuerdo de paz.
La educación en ciudadanía en el pensamiento de Adela Cortina
Authors: HERNÁNDEZ ACEVEDO ÁLVARO
Published: December 2018

Este artículo de reflexión es producto de una investigación titulada “Formación de ciudadanos del mundo: un estudio de IAP y ApS desde la glocalidad y la pedagogía crítica en un contexto de educación superior”. El objetivo es presentar la comprensión de la educación en ciudadanía según Adela Cortina, bajo la metodología Investigación-Acción-Participación, y la propuesta didáctico-metodológica de Aprendizaje por Servicio. Se logró determinar que la formación de los ciudadanos parte del pensar global y actuar localmente bajo los principios del diálogo, del consenso, de la justicia y la democracia, vinculando la relación dinámica acción-lenguaje-pensamiento-mundo, desde la vida cotidiana al aula de clase como un ejercicio dialógico entre sujetos agentes que se cuestionan en relación con su mundo vital. De no ser así, la formación de ciudadanos se convierte en un discurso vacío de contenido de las políticas públicas en educación y de los proyectos educativos de las instituciones educativas.

Analisis Penerapan Sanksi Administrasi Pada Pelaksanaan Pengelolaan Limbah Medis di Rumah Sakit Umum Daerah Raden Mattaher Jambi
Authors: Raharja Ivan Fauzani
Published: December 2018

Limbah medis sangat penting untuk dikelola secara benar, hal ini mengingat limbah  medis  termasuk  ke  dalam  kategori  limbah  berbahaya  dan  beracun. Sebagian limbah  medis  termasuk  kedalam  kategori  limbah  berbahaya  dan sebagian lagi termasuk kategori infeksius. Berkaitan dengan masalah pengelolaan limbah RSUD Raden Mattaher Jambi, kementerian lingkungan hidup memberikan label hitam pada tahun 2014 artinya dalam pengelolaan limbahnya sangat buruk dan hal itu dapat berdampak pengenaan sanksi administrasi yang akan diterima oleh RSUD Raden Mattaher Jambi. Menurut Pasal 198 Peraturan Pemerintah Nomor 101 Tahun 2014 Tentang Pengelolaan Limbah Bahan Berbahaya Dan Beracun  ”Setiap Orang yang menghasilkan Limbah B3, Pengumpul Limbah B3, Pengangkut Limbah B3, Pemanfaat Limbah B3, Pengolah Limbah B3, dan/atau Penimbun Limbah B3 yang melakukan Pencemaran Lingkungan Hidup dan/atau Perusakan Lingkungan Hidup wajib melaksanakan: a. Penanggulangan Pencemaran Lingkungan Hidup dan/atau Kerusakan Lingkungan Hidup; dan b. Pemulihan Fungsi Lingkungan Hidup. Dengan adanya peraturan perundang- undangan tersebut seharusnya pengelolaan limbah rumah sakit harus berpedoman pada peraturan  yang  berlaku.  apabila  hal  tersebut  tidak  diterapkan  maka pemerintah  berhak  mengenakan  sanksi  administrasi  terhadap  masalah  tersebut baik itu berupa pencabutan izin sementara ataupun bentuk lain yang telah ditetapkan.

Investor Reaction to Disclosure of Past Performance and Future Plans
Authors: Emett Scott A.
Published: December 2018

I examine how and why current-period performance shapes investors' evaluations of future-oriented disclosures. Three experiments provide evidence that a firm's current-period performance shapes investors' beliefs about the appropriateness of managerial optimism, which, in turn, affects investors' evaluation of firms that focus on either challenges or opportunities in future-oriented disclosures. When a firm is performing poorly, investors believe that managers can best achieve success by being optimistic about the future and, therefore, invest more when the firm focuses on opportunities rather than challenges in future-oriented disclosures. When a firm is performing well, on the other hand, investors believe that managers can best achieve success by being realistic about the future and, therefore, invest more when the firm focuses on challenges rather than opportunities.
Adhesive precoated bracket systems and operator coated bracket systems: Is there any difference? A systematic review and meta-analysis
Authors: Alakttash Ahmed Mohamed , Fawzi Mohamed , Bearn David
Published: December 2018

Objectives:

To investigate whether adhesive precoated brackets (APC) are more efficient than operator-coated brackets (OPC) regarding failure rate, bonding time, patient experience, gingival health, plaque accumulation, and white spot lesion formation.

Materials and Methods:

Five online databases: Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, PubMed, MEDLINE, and Web of Science were searched for potential eligible randomized controlled trials (RCTs). A Google Scholar and gray literature search was undertaken. References of included studies were screened for potential eligible studies. Results were collated from each database and modified Cochrane data extraction forms were completed. Quality assessment was performed using Cochrane RoB 2.0 tool for RCTs.

Results:

Five studies met the inclusion criteria. All reported failure rates using metal brackets for both APC and OPC systems except one that compared clear APC to clear OPC. Three studies reported bonding time differences between the bracket systems. A quantitative synthesis of four studies reporting failure and three reporting bonding time was undertaken. Random effect meta-analysis determined there were no statistically significant differences in bond failures between bracket systems with an odds ratio of 0.890 (P = .808). Bonding time showed a statistically significant (P = .01) but not clinically significant shorter bonding time with OPC. There was insufficient evidence to assess plaque accumulation, gingival health, and either patient or operator experience.

Conclusions:

There is no superiority of either bracket system regarding failure rate. OPC are statistically significantly superior over APC in bonding time although this is most likely not clinically significant.

Published: December 2018

ResumoAtualmente, pensar no acesso do aluno com deficiência em sala de aula se faz essencial uma vez que todos têm o direito à educação e de estar presente de forma real na sociedade. Falando especialmente do aluno cego, este requer uma metodologia de ensino condizente com suas limitações e que valorize sua potencialidade. Assim, o objetivo desse trabalho é divulgar a experiência da confecção de uma Tabela Periódica adaptada para o Braille e que foi trabalhada em aulas de química junto a dois estudantes cegos, valorizando a história da descoberta dos elementos químicos e de sua organização até a Tabela atual. A partir dos resultados advindos dessa experiência ressaltamos que os alunos com deficiência visual necessitam de recursos didáticos e adaptações curriculares específicos para que possam participar ativamente da construção de sua aprendizagem e, para tanto, as abordagens da História da Ciência se mostram essenciais nesse processo.Palavras-chave: Inclusão; cegos; história da química.AbstractCurrently, thinking about disabled students' access to the classroom is essential since everyone has the right to education and to be present in society. Especially about the blind student, this requires a teaching methodology that is consistent with its limitations and that values its potentiality. Thus, the objective of this work is to divulge the experience of producing a Periodic Table adapted for Braille and that was used in chemistry classes with two blind students, valuing the history of the discovery of the chemical elements and of their organization up to the current Table. Based on the results of this experience, we emphasize that students with visual impairments need didactic resources and specific curricular adaptations so that they can participate actively in the construction of their learning and for this, the approaches of the History of Science are essential in this process.Keywords : Inclusive; blind; history of chemistry.
O essencialismo na classificação de Lineu e a repercussão dessa controvérsia na Biologia
Authors: Klepka Verônica , Corazza Maria Julia
Published: December 2018

ResumoNos últimos dois séculos, Lineu e toda taxonomia tradicional têm sido acusados de exercerem uma prática essencialista, pautada na descrição de tipos. Ernest Mayr foi um dos que contribuíram para disseminar essas ideias que passaram a ser consideradas como verdades na Biologia. Entretanto, nas últimas duas décadas, historiadores e filósofos da Biologia contestaram esse argumento oferecendo novas análises que corrigem o anacronismo efetuado na história das classificações biológicas. Neste artigo, nosso objetivo é argumentar, com o auxílio de obras originais de Lineu e fontes secundárias provenientes de estudiosos da vida e do trabalho do sueco, bem como de historiadores e filósofos da Biologia, por que a classificação biológica lineana não é fundamentada no essencialismo platônico ou aristotélico. Observamos que as obras e o contexto de Lineu foram mal interpretados, que suas influências na ciência eram totalmente contrárias à lógica escolástica e que, apesar de usar termos como essência, gênero e espécie em suas obras, não há qualquer relação com a lógica aristotélica. Palavras-chave: Carl von Linné; Classificação dos Seres Vivos; História da Ciência.  AbstractIn the last two centuries, Linnaeus and all traditional taxonomy has been accused of exercising an essentialist practice, based on the description of types. Ernst Mayr was one of those who contributed to disseminate these ideas that came to be considered as truths in Biology. However, in the last two decades historians and philosophers of biology have contested this argument by offering new analyzes that correct the anachronism in the history of biological classifications. In this article, our objective is to argue, with the help of original works by Linnaeus and secondary sources from scholars of the life and work of the Swedish, as well as historians and philosophers of Biology, because the linear biological classification is not based on essentialism Platonic or Aristotelian. We note that Linnaeus' works and context were misinterpreted, that his influences on science were wholly contrary to scholastic logic, and that in spite of using terms like essence, genus, and species in his works, he had no connection with Aristotelian logic. Keywords: Carl von Linné; Classification of Living Beings; History of Science.

La pareja frente a la movilidad laboral. Los pernoctadores en la Bretaña contemporánea
Authors: Charrier Gilda
Published: December 2018

El presente artículo estudia uno de los problemas actuales que afrontan las familias ante la emergencia de los nuevos desafíos de la vida moderna. Se trata de un estudio de caso circunscripto a la Bretaña francesa, aunque el ejemplo estudiado bien puede ser representativo de otros. El caso es el de una familia nuclear donde cada cónyuge trabaja pero, uno de ellos –el varón- lo hace en un lugar muy distante de la casa familiar. A partir de tal situación, se explora con un enfoque que proviene de la sociología y de los estudios de género, la implicancia de esa situación en el plano tanto individual laboral, como en los roles, la organización familiar y los deseos compartidos.
KEDUDUKAN BANK SEBAGAI KREDITOR SEPARATIS DALAM PENGURUSAN DAN PEMBERESAN HARTA PAILIT
Authors: Pakel Yane
Published: December 2018

There are two purpose of this research 1) to know and analyze banks role as secured creditor in executing collaterals. This is cause by the uncertainty of the execution rights as a result of the inconsistencies of regulations mention to Article 55, Article 56 and Article 59 of The Republic of Indonesia Number 37 of 2004 regarding Bankruptcy and Suspension of Payment Obligation. 2) to know and examine the legal protection for secure banks in bankruptcy settlement. This research is a normative legal research that is supported by interview. Secondary data is taken from primary, secondary and tertiary legal resource. Data collection method is documentary study and library research. Data analysis is a qualitative analysis.Based on the result and discussion, bank as a secured creditor has the right to execute collateral that is pledged by debtor, as if bankruptcy does not take place (pursuant to Article 55 paragraph 1)The bankruptcy law has ruled the creditors right on the collateral, but there is uncertainty of execution right. This is caused by the inconsistency of regulations of Article 55, Article 56 and Article 59 of The Republic of Indonesia Number 37 of 2004 regarding Bankruptcy and Suspension of Payment Obligation. Article 56 and Article 59 are limit the creditors rights. The current law does not strongly enforced, thus the bank is seeking right by auction or hidden transaction

Published: December 2018

The growth of seven exotic true fir (Abies) species and native Abies alba have been compared in three provenance trials in the Czech Republic, at the relatively advanced ages of 44, 38, and 35 years respectively. A clear differentiation is observable between the species. The closely related species group of A. alba and A. cephalonica appears rather heterogeneous in its phenotypic behavior. A. alba provenances show superiority, but also a high differentiation. Productivity of provenances of A. cephalonica fall behind A. alba; however A. cilicica and A. pinsapo provenances have shown total mortality. The high potential of A. grandis is confirmed by outstanding growth; provenances from the coastal plain in Washington State performed best. A. procera grows slower than A. grandis, but still faster than A. alba provenances. Health risks, extreme ecologic distances of transfer, trend shifts of growth rate, and rank change with age are uncertainties that require necessary caution when selecting provenances for importation. In recent years, public and institutional perceptions concerning the introduction of non-native tree species and provenances has shifted, and the practice is no longer seen as necessarily inappropriate.
Adapting Hellwig’s method for selecting concomitant variables under a certain growth curve model
Authors: Wesołowska-Janczarek Mirosława , Różańska-Boczula Monika
Published: December 2018

This paper presents an application of Hellwig’s method for selecting concomitant variables under a growth curve model, where the values of the concomitant variables change over time and are the same for all experimental units. The authors present a simple adaptation of the growth curve model to the multiple regression model for which Hellwig’s method applies. The theoretical considerations are applied to the selection of significant concomitant variables for raspberry fruiting.
On a new approach to the analysis of variance for experiments with orthogonal block structure.
Authors: Caliński Tadeusz , Siatkowski Idzi
Published: December 2018

The main estimation and hypothesis testing procedures are presented for experiments conducted in nested block designs of a certain type. It is shown that, under appropriate randomization, these experiments have the convenient orthogonal block structure. Due to this property, the analysis of experimental data can be performed in a comparatively simple way. Certain simplifying procedures are indicated. The main advantage of the presented methodology concerns the analysis of variance and related hypothesis testing procedures. Under the adopted approach one can perform these analytical methods directly, not by combining the results from analyses based on stratum submodels. The application of the presented theory is illustrated by three examples of real experiments in relevant nested block designs. The present paper is the second in the planned series concerning the analysis of experiments with orthogonal block structure.
Linear Markovian models for lag exposure assessment
Authors: Magrini Alessandro
Published: December 2018

Linear regression with temporally delayed covariates (distributed-lag linear regression) is a standard approach to lag exposure assessment, but it is limited to a single biomarker of interest and cannot provide insights on the relationships holding among the pathogen exposures, thus precluding the assessment of causal effects in a general context. In this paper, to overcome these limitations, distributed-lag linear regression is applied to Markovian structural causal models. Dynamic causal effects are defined as a function of regression coefficients at different time lags. The proposed methodology is illustrated using a simple lag exposure assessment problem.
A New Horizo-Vertical Distributed Feature Selection Approach
Authors: Zerhari B. , Lehcen A. Ait , Mouline S.
Published: December 2018

Feature selection technique has been a very active research topic that addresses the problem of reducing the dimensionality. Whereas, datasets are continuously growing over time both in samples and features number. As a result, handling both irrelevant and redundant features has become a real challenge. In this paper we propose a new straightforward framework which combines the horizontal and vertical distributed feature selection technique, called Horizo-Vertical Distributed Feature Selection approach (HVDFS), aimed at achieving good performances as well as reducing the number of features. The effectiveness of our approach is demonstrated on three well-known datasets compared to the centralized and the previous distributed approach, using four well-known classifiers.

The system is evaluated based on criteria specified by the researchers and abnormal packets.
Macroeconomic effects of the budget deficit in the Republic of Macedonia
Authors: Noveski Martin
Published: December 2018

Although a decade has passed since the global financial and economic crisis of 2008, the expansionary fiscal policy in Macedonia can still be felt, primarily through an increased level of public expenditures aimed at stimulation of the economic growth. From 2008 onwards, the Republic of Macedonia has continuously recorded a negative budget balance, which affects the resources allocation and the overall economic situation. The question that arises is whether such interference by the Government in the functioning of the market economy is necessary, especially having in mind the EU regulation in this area. Using a multiple regression model for the period 1996-2015, this paper examines the impact of the budget deficit on Gross Domestic Product (GDP) per capita in Macedonia. Results show that the budget deficit is not a statistically significant determinant of GDP per capita, supporting thus the Ricardian equivalence theory. The analysis is conducted on the basis of statistical data from the World Bank’s database, as well as data from the National Bank of the Republic of Macedonia. Household final consumption expenditure, the unemployment rate and the official exchange rate of the Macedonian Denar against the U.S. Dollar are also taken into consideration as controlling variables. GDP per capita and household final consumption expenditures are in current prices, with natural logarithms applied, whereas the other variables are in nominal terms. The purpose of this paper is to provide an insight into the empirical relationship between the two main variables of interest and to initiate further discussion and analysis.
Probabilistic sampling strategy as a means of improving quality of price indices
Authors: Seljak Rudi , Bregar Lea , Colić Sanda , Dozet Maja
Published: December 2018

In spite of theoretical inferiority, a large majority of statistical institutes use non-probabilistic sampling techniques in price surveys. The main disadvantage of non-probabilistic sample design is that the risk of biased results is increased. Attempting to handle this risk in the domain of service producer price indices (SPPI) of professional services, the Croatian Bureau of Statistics (CBS) developed an innovative methodology and implemented it relying on the probability proportional to size (PPS) sample design. The purpose of the paper is to evaluate the impact of the probabilistic sampling strategy on the quality of price indices as shown in the case of SPPI for professional services at the CBS. The paper outlines respective methodological upgrading of SPPI compilation at the CBS, including also the method for variance estimation. The effect of the probabilistic sampling on SPPI is analysed by comparison with traditional purposive sampling surveys. The quality of SPPI based on the probabilistic sample approach is examined by coefficients of variation and confidence intervals.
A new link function for the prediction of binary variables
Authors: Gheno Gloria
Published: December 2018

If there are no heavy sanctions in place to prevent it, the problem of the cancellation of appointments can lead to huge economic losses and can have a significant impact on underutilized resources of healthcare facilities. A good model to predict the appointment cancellations could be an effective solution to this problem. Therefore, a new Bayesian method is proposed to estimate accurately the probability of the cancellation of visits to healthcare institutions based on specific factors such as age. This model uses the regression for binary variables, linking the explanatory variables to the probability of appearance at a previously made appointment with a new weighted function and estimating the parameters with the Bayesian method. The goodness of the new method is demonstrated by applying it to a real case and by comparing it to other methodologies. Therefore, the advantages of the proposed method are exposed and possible real-world applications are described.
