Authors: Escobar Marco A. , Guzmán Sepúlveda José R. , Parra Michel Jorge R. , Guzmán Cabrera Rafael
Published: May 2019

Introduction: We propose a novel approach for the assessment of the similarity of retinal vessel segmentation images that is based on linking the standard performance metrics of a segmentation algorithm, with the actual structural properties of the images through the fractal dimension.Method: We apply our methodology to compare the vascularity extracted by automatic segmentation against manually segmented images.Results: We demonstrate that the strong correlation between the standard metrics and fractal dimension is preserved regardless of the size of the subimages analyzed.Discussion or Conclusion: We show that the fractal dimension is correlated to the segmentation algorithm’s performance and therefore it can be used as a comparison metric.
Cellular Stress and General Pathological Processes
Authors: Gusev Eugeny Yu. , Zotova Natalia V.
Published: May 2019

:

From the viewpoint of the general pathology, most of the human diseases are associated with a limited number of pathogenic processes such as inflammation, tumor growth, thrombosis, necrosis, fibrosis, atrophy, pathological hypertrophy, dysplasia and metaplasia. The phenomenon of chronic low-grade inflammation could be attributed to non-classical forms of inflammation, which include many neurodegenerative processes, pathological variants of insulin resistance, atherosclerosis, and other manifestations of the endothelial dysfunction. Individual and universal manifestations of cellular stress could be considered as a basic element of all these pathologies, which has both physiological and pathophysiological significance.

:

The review examines the causes, main phenomena, developmental directions and outcomes of cellular stress using a phylogenetically conservative set of genes and their activation pathways, as well as tissue stress and its role in inflammatory and para-inflammatory processes.

:

The main ways towards the realization of cellular stress and its functional blocks were outlined. The main stages of tissue stress and the classification of its typical manifestations, as well as its participation in the development of the classical and non-classical variants of the inflammatory process, were also described.

:

The mechanisms of cellular and tissue stress are structured into the complex systems, which include networks that enable the exchange of information with multidirectional signaling pathways which together make these systems internally contradictory, and the result of their effects is often unpredictable. However, the possible solutions require new theoretical and methodological approaches, one of which includes the transition to integral criteria, which plausibly reflect the holistic image of these processes.
Temperature Rise Prediction of Oil-Air Lubricated Angular Contact Ball Bearings Using Artificial Neural Network
Authors: Wang Baomin , Chang Xiao
Published: May 2019

Background:

Angular contact ball bearing is an important component of many high-speed
rotating mechanical systems. Oil-air lubrication makes it possible for angular contact ball bearing to
operate at high speed. So the lubrication state of angular contact ball bearing directly affects the performance
of the mechanical systems. However, as bearing rotation speed increases, the temperature rise
is still the dominant limiting factor for improving the performance and service life of angular contact
ball bearings. Therefore, it is very necessary to predict the temperature rise of angular contact ball bearings
lubricated with oil-air.

Objective:

The purpose of this study is to provide an overview of temperature calculation of bearing
from many studies and patents, and propose a new prediction method for temperature rise of angular
contact ball bearing.

Methods:

Based on the artificial neural network and genetic algorithm, a new prediction methodology
for bearings temperature rise was proposed which capitalizes on the notion that the temperature rise of
oil-air lubricated angular contact ball bearing is generally coupling. The influence factors of temperature
rise in high-speed angular contact ball bearings were analyzed through grey relational analysis, and
the key influence factors are determined. Combined with Genetic Algorithm (GA), the Artificial Neural
Network (ANN) model based on these key influence factors was built up, two groups of experimental
data were used to train and validate the ANN model.

Results:

Compared with the ANN model, the ANN-GA model has shorter training time, higher accuracy
and better stability, the output of ANN-GA model shows a good agreement with the experimental
data, above 92% of bearing temperature rise under varying conditions can be predicted using the ANNGA
model.

Conclusion:

A new method was proposed to predict the temperature rise of oil-air lubricated angular
contact ball bearings based on the artificial neural network and genetic algorithm. The results show that
the prediction model has good accuracy, stability and robustness.
RE-CONCEIVING REFUGEE SITUATIONS FROM A DEVELOPMENT PERSPECTIVE. PROVIDING DURABLE SOLUTIONS FOR REFUGEES THROUGH DEVELOPMENT
Authors: Kaga Midori T
Published: May 2019

!is paper examines the changing character of forced displacement and its impact on the lives of refugees and their host countries. !e paper proposes the need to re-conceptualize the issue of refugees from a development perspective, recognizing that the forced displacement resulting in refugee situations is both a product and cause of development (or lack thereof ). Conceiving of refugee situations within a broader development perspective provides a constructive path for the international community to provide truly durable solutions that can expand people’s freedoms, opportunities and capabilities to achieve a fulfilling life and reduce global inequal-ities and instability. !e first section discusses the failure of states to facilitate the three durable solutions in the face of the changing character of refugee movements. !e second section proposes reconceiving refugee situations as a development issue, the need for bridging the humanitarian-development gap, and the need for counteracting the negative discourse surrounding refugees in order to build on the opportunities that refugees present. !e third section provides examples to demon-strate how refugees are creating livelihood solutions for themselves, the contribu-tions they are making to their host societies, and how development-led solutions can help support refugees and better manage the long-term developmental conse-quences of protracted refugee situations.
Atuação da equipe de enfermagem no parto humanizado e seus benefícios diante o parto cesárea
Authors: Gomes Mirian Aparecida , Abi Rached Chennyfer Dobbins
Published: May 2019

Introdução: O parto é um processo natural e fisiológico, porém após a institucionalização desse processo, o parto tornou-se mecanizado. A definição acerca da via de parto sofre influência de diversos fatores, dentre os quais se destacam: riscos e benefícios, possíveis complicações e repercussões futuras. Objetivos: Identificar os malefícios do parto cesárea junto às suas possíveis complicações quando comparados ao parto humanizado; Descrever a atuação da equipe de enfermagem no parto humanizado. Método: Pesquisa bibliográfica em bases de dados LILACS e SCIELO, e na biblioteca eletrônica Biblioteca Virtual em Saúde (BVS) de artigos de periódicos nacionais, sendo textos de língua portuguesa, disponíveis gratuítos na íntegra e a partir do ano de 2013. Desenvolvimento: A cesariana sem indicação clínica quando comparada ao parto vaginal está relacionada com maior morbidade materna, como a necessidade de transfusão sanguínea, histerectomia, internação em UTI e piores desfechos neonatais, enquanto o parto humanizado passa por um modelo assistencial que proporciona a mulher benefícios físicos e psicológicos. O enfermeiro ao elaborar intervenções voltadas para as reais necessidades das puérperas, qualifica o cuidado prestado com a contribuição de forma decisiva. Considerações Finais: O parto normal é um desafio para as mulheres, porém benéfico em relação à cesárea, que por sua vez, apesar de ser mais rápida e cômoda, pode acarretar em diversar complicações materno-fetal.
Predicting Posttraumatic Stress Disorder Risk: A Machine Learning Approach
Authors: Wshah Safwan , Skalka Christian , Price Matthew
Published: May 2019

Background

A majority of adults in the United States are exposed to a potentially traumatic event but only a handful go on to develop impairing mental health conditions such as posttraumatic stress disorder (PTSD).

Objective

Identifying those at elevated risk shortly after trauma exposure is a clinical challenge. The aim of this study was to develop computational methods to more effectively identify at-risk patients and, thereby, support better early interventions.

Methods

We proposed machine learning (ML) induction of models to automatically predict elevated PTSD symptoms in patients 1 month after a trauma, using self-reported symptoms from data collected via smartphones.

Results

We show that an ensemble model accurately predicts elevated PTSD symptoms, with an area under the curve (AUC) of .85, using a bag of support vector machines, naive Bayes, logistic regression, and random forest algorithms. Furthermore, we show that only 7 self-reported items (features) are needed to obtain this AUC. Most importantly, we show that accurate predictions can be made 10 to 20 days posttrauma.

Conclusions

These results suggest that simple smartphone-based patient surveys, coupled with automated analysis using ML-trained models, can identify those at risk for developing elevated PTSD symptoms and thus target them for early intervention.

El pensar histórico como genealogía: acto interpretativo y construcción de subjetividad
Authors: Melgarejo Acosta María del Pilar
Published: May 2019

El presente artículo pretende aproximarse desde una perspectiva filosófica a un carácter particular del pensar histórico: la genealogía. Se trata de una reflexión acerca del modelo genealógico no sólo como análisis histórico, donde la mirada del historiador es comprendida como acto interpretativo, sino como generador de saber y productor de subjetividad. La genealogía abre la posibilidad de que las ciencias sociales puedan reconocerse como labor histórica para repensar así los modos en que problematizan su presente.

Published: May 2019

Chrysanthemum morifolium cv. ?Huaihuang? has great medicinal and commercial value. However, limited genomic and transcriptional information restricts the further research of ?Huaihuang?. In this study, using ?Huaihuang? leaf as the sample, we performed RNA-Seq and obtained numerous unigene sequences for functional characterization, and developed new EST-SSR markers. The results show that 176 unigenes were assigned to the ?antioxidant activity? in GO annotations, 998 unigenes were assigned to ?Secondary metabolite biosynthesis, transport and catabolism? in the KOG database, 381 unigenes were assigned to ?Biosynthesis of other secondary metabolites?, and 377 unigenes were assigned to ?Metabolism of terpenoids and polyketides? in the KEGG database. A number of genes involved in the biosynthesis of flavones and terpenes, such as CHS, CHI, FLS, HMGR and MVD, were found in the transcription data of ?Huaihuang?. Also, 36 new polymorphic EST-SSR markers were developed and validated. Using them, the genetic diversity was analyzed and a dendrogram of six clades was constructed among 15 medicinal chrysanthemum varieties. The excavated unigenes and identified new ESTSSR markers will provide useful resources for the study of biosynthesis of active components, genetic diversity analysis, population structure identification and in molecular breeding research of ?Huaihuang? and related species.

Understanding Idiopathic Spinal Cord Herniation – A Comprehensive Review of Imaging and Literature
Authors: Sharma Pranav , Soin Priti , Elbanan Mohamed , Kochar Puneet Singh
Published: May 2019

Idiopathic spinal cord herniation (ISCH) is displacement of spinal cord through a dural or arachnoidal defect. Most patients present with back pain or myelopathy, paresthesia, and sensory or motor weakness. Imaging findings include anterior displacement of the cord with possible kink, no filling defect on CT myelography, and no restricted diffusion/mass lesion on magnetic resonance imaging. Abrupt kink in the spinal cord or widened cerebrospinal fluid (CSF) space can be caused by a variety of reasons. The differential considerations include arachnoid web, intradural extramedullary epidermoid or arachnoid cyst, abscess or cystic schwannoma. We discuss the features, imaging, differentials, and treatment of ISCH as a rare cause of such kink in the cord. While reading such cases, a radiologist should include the location, segments involved, cord signal abnormality, visible defect, scalpel sign or C–sign, ventral cord kink, nuclear trail sign, the ventral CSF space preservation, or obliteration and the type.
Molecular Transformer – A Model for Uncertainty-Calibrated Chemical Reaction Prediction
Authors: Schwaller Philippe , Laino Teodoro , Gaudin Theophile , Bolgar Peter , Bekas Costas , Lee Alpha A.
Published: May 2019

Organic synthesis is one of the key stumbling blocks in medicinal chemistry. A necessary yet unsolved step in planning synthesis is solving the forward problem: given reactants and reagents, predict the products. Similar to other work, we treat reaction prediction as a machine translation problem between SMILES strings of reactants-reagents and the products. We show that a multi-head attention Molecular Transformer model outperforms all algorithms in the literature, achieving a top-1 accuracy above 90% on a common benchmark dataset. Our algorithm requires no handcrafted rules, and accurately predicts subtle chemical transformations. Crucially, our model can accurately estimate its own uncertainty, with an uncertainty score that is 89% accurate in terms of classifying whether a prediction is correct. Furthermore, we show that the model is able to handle inputs without reactant-reagent split and including stereochemistry, which makes our method universally applicable.
DoE-It-Yourself: A Case Study for Implementing Design of Experiments into Nanoparticle Synthesis
Authors: Fhionnlaoich Niamh Mac , Yang Ye , Qi Runzhang , Galvanin Federico , Guldin Stefan
Published: May 2019

Predictable and repeatable outcome is a major issue in nanoparticle synthesis. Traditionally, chemists rely on the one-factor-at-a-time method to investigate and optimise synthetic processes; however, this method is inefficient and often misleading. Design of Experiments (DoE), in contrast, can provide a greater amount of information in fewer experiments and lends itself to producing more reproducible results. Nevertheless, DoE techniques are only used by a relatively low number of practitioners in nanoparticle research. Here, we provide a case study on the synthesis of oleylamine-capped gold nanoparticles (AuNPs). Through the use of DoE, we achieved a marked reduction in dispersity and developed a model to carefully control the mean diameter of the nanoparticle populations.
XPS of Cold Pressed Multilayered and Freestanding Delaminated 2D Thin Films of Mo2TiC2Tz and Mo2Ti2C3Tz (MXenes)
Authors: Halim Joseph , Cook Kevin , Eklund Per , Rosen johanna , Barsoum Michel W.
Published: May 2019

MXenes, transition metal carbides that are synthesized from the top down by etching of their 3D parent layered solids, the MAX phases, are the latest family of the two-dimensional solids discovered. When the A layers – mostly Al – are etched they are replaced by surface terminations, Tz mainly comprised of O-, OH- and F-terminations. One of the few techniques capable of quantifying these surface terminations is X-ray photoelectron spectroscopy, XPS. Herein, we undertook an XPS study of the out-of-plane ordered MXenes, Mo2TiC2Tz and Mo2Ti2C3Tz, in both multilayered, ML, cold pressed and delaminated thin film forms. The harsh conditions needed to etch these MAX phases into MLs, results in their partial oxidation. The hydroxide used to delaminate the MLs results in further oxidation and a reduction in the F-content. In all cases, etching resulted in a decrease in the Ti to Mo ratio implying that the former atoms are selectively etched. In all but the ML Mo2TiC2Tz case, the Mo to C ratio was also reduced. It follows that the loss of Ti also results in the loss of C atoms. With the exception of the ML Mo2Ti2C3Tz case, the number of termination moles per formula unit, z, was > 2, which is energetically unfavorable and thus unlikely. However, if one assumes that not all of the O signal is coming from terminations but rather from O atoms that replace C atoms in the MX blocks, then z ≈ 2. This work is an important step in quantifying and understanding the effects of etching on terminations and structure in these Mo and Ti-based MXenes.
Asymmetric Total Synthesis of Arcutinidine and Arcutinine
Authors: Zhou Shupeng , Xia Kaifu , Li Ang
Published: May 2019

We have accomplished the asymmetric total synthesis of arcutinidine and arcutinine, two arcutine-type C20-diterpenoid alkaloids. A pentacyclic intermediate was rapidly assembled by using two Diels−Alder reactions. A cascade sequence of Prins cyclization and Wagner−Meerwein rearrangement was then developed to construct the core of arcutinidine, which was further elaborated into an oxygenated pentacycle through a scalable route. Chemoselective reductive amination followed by spontaneous imine formation furnished the pyrroline motif at a final stage.
Total Synthesis of the Diterpenoid Alkaloid Arcutinidine Using a Strategy Inspired by Chemical Network Analysis
Authors: Owens Kyle , McCowen Shelby , Blackford Katherine , Ueno Sohei , Hirooka Yasuo , Weber Manuel , Sarpong Richmond
Published: May 2019

Arcutinidine and other arcutinidine-type diterpenoid alkaloids feature an intricate polycyclic, bridged framework with unusual connectivity. A chemical network analysis approach to the arcutane skeleton enabled the identification of highly simplifying retrosynthetic disconnections, which indicated that the caged structure could arise from a simpler fused ring system. On this basis, a total synthesis of arcutinidine is reported herein, featuring an unprecedented oxopyrrolium Diels–Alder cycloaddition which furnishes a key tetracyclic intermediate. In addition, the synthesis utilizes a diastereoselective oxidative dearomatization/cycloaddition sequence and a SmI2-mediated C–C coupling to forge the bridged framework of the natural products. This synthetic plan may also enable future investigations into the biosynthetic relationships between the arcutanes, the related diterpenoid atropurpuran, and other diterpenoid alkaloids.
Juventude em foco:
Authors: Oliveira Ana Cristina De Oliveira , Barbosa Carlos Soares , Motta Vânia Cardoso da
Published: May 2019

Este artigo incorpora estudos e pesquisas que estão sendo realizados em nível de doutorado e discutidos no âmbito de um grupo de pesquisa que abrange os campos da assistência social e da educação. Seu recorte traz a discussão das atuais políticas educacionais voltadas para a juventude brasileira, predominantemente articuladas com as políticas sociais. Os autores apresentam essa articulação associada ao projeto societário “novo-desenvolvimentista” do atual governo Lula, sem, contudo, considerar uma especificidade, mas um movimento amplo e externo voltado para atribuir uma face mais humana ao capitalismo e operar condições favoráveis à acumulação do capital na virada do milênio – estabilidade econômica e política. Aborda a discussão sobre a compreensão da “nova questão social”, os encaminhamentos de política pública dos governos de Fernando Henrique Cardoso e Luiz Inácio Lula da Silva e de políticas educacionais voltadas para jovens considerados em situação de “vulnerabilidade social” ou “situação de risco social”.

BREVE CARTOGRAFIA DA DISCUSSÃO SOBRE FAMÍLIA
Authors: Miranda Gomes da Silva Vanessa
Published: May 2019

O presente artigo apresenta o denominado “estado da arte” acerca do debate sobre família. Seu desenvolvimento foi realizado com base no levantamento das publicações abrigadas na base SciELO e nas revistas não indexadas da área do Serviço Social, de circulação nacional. Constatou-se que o interesse pela temática família aumentou nos últimos anos, tendo sua abordagem concentrada nos impactos da transformação social na família, sobre a sua relação com o Estado e sua centralidade nas políticas e programas sociais, e sobre as concepções e atribuições utilizadas no cotidiano profissional. Contudo, pelo fato de a família fazer parte do cotidiano de todas as pessoas, a discussão sobre a prática profissional permanece secundarizada.

Authors: Sum Ngai-Ling
Published: May 2019

O artigo analisa o Brasil e a China no desenvolvimento dos discursos transnacionais sobre as economias dos países que compõem o BRIC. O texto faz uma avaliação crítica deste desenvolvimento em três partes. A primeira parte do artigo estuda como os atores transnacionais introduziram o BRIC como um imaginário econômico e desenvolveram esse discurso. A segunda seção examina a base material para a ressonância desse discurso, isto é, as forças que o sustentam e o acompanham, a partir das taxas excepcionais de crescimento das economias do BRIC. Nesta seção introduz-se a ideia do “PIBismo” para capturar a natureza ideológica dessa política de desenvolvimento na China. A terceira parte do texto aborda o regime de Bem-Estar Ricardiano (Workfariano), baseado em ativos; e destaca suas vulnerabilidades ao compor um ciclo vicioso de apropriação de terras, inflação e instabilidade social. Por fim o artigo convida os leitores a refletir sobre a experiência social e política brasileira, especialmente sobre o papel da política social e, em particular, da assistência social, à luz da política de desenvolvimento da China.
Expressões e tendências da participação em saúde na Atenção Primária à Saúde
Authors: Oliveira Andreia
Published: May 2019

Neste artigo, a autora reflete sobre o tema da participação em saúde e suas expressões e tendências na Atenção Primária à Saúde – APS, na sociedade brasileira, com base em elementos da teoria crítica que fecunda a compreensão da dinâmica da sociedade capitalista contemporânea. Para tanto, fundamenta a interlocução com autores que advogam análises de compreensão da democracia segundo a perspectiva teórica do materialismo histórico-dialético, como também na perspectiva gramsciana de sociedade civil e hegemonia. Enfatiza-se o aprofundamento, no setor saúde, das expressões da questão social e de seus desdobramentos, em termos da impermeabilidade da participação popular no âmbito da Atenção Primária à Saúde – APS. Com o entendimento de que as estratégias participacionistas, por si só, não possuem capacidade de transformação da sociedade capitalista, a autora enfoca a relevância da participação em saúde na APS, de modo a valorizar os componentes político-educativo, de mobilização e organização popular, os quais contribuam à ampliação das bases política e social, na luta pelo direito à saúde pública, estatal e com qualidade.

A good quality of educational institutions is very important nowadays. Currently, there are many educational institutions that are not qualified by considering from grade of national education. It is still low. In addition, there are some basics schools, high and university that have not been accredited or achieved grade C. The lack of education institutions will lead to rising unemployment and crime. In addition, the nation's competitiveness will also be low in facing global competition. To improve good quality of educational institutions, it needs to work high and state a commitment together. The existence of a good quality of educational institutions can be seen from the improvement of culture, structure, access, systems and relationship with stakeholders. Management of human resources in educational institutions is also a key quality of the educational institution.

farklı yöntemlerden faydalanılmaktadır. Yöntemler arasında farklılık oluşturan
en önemli etkenin ekstraksiyon prosedürü olduğu düşünülmektedir. Bu çalışma üç
farklı yağ ekstraksiyon yönteminin mısırda karotenoid içeriğini tespit etmeye
yönelik yapılan analiz sonuçlarına etkisini belirlemek amacıyla yürütülmüştür.
Çalışmada bitkisel materyal olarak 150 farklı mısır genotipi değerlendirmeye
alınmıştır. Ekstraksiyon yöntemi olarak Soxhlet (sıcak ekstraksiyon), soğuk
(solvent) ekstraksiyon ve doğrudan ekstraksiyon yöntemleri kullanılmıştır. Bu
yöntemler ile elde edilen yağların karotenoid içeriği tespiti
UV-Spektrofotometre cihazı ile 450 nm dalga boyunda gerçekleştirilmiştir. Yöntemlere
ait ortalamalar Kruskal-Wallis testi ile kıyaslanmış ve analiz sonuçları
arasındaki ilişkiler basit doğrusal regresyon analizi ile incelenmiştir.
Soxhlet ekstraksiyonu ile elde edilen yağlar karotenoid içerikleri bakımından
diğer yöntemlerden daha yüksek değerler vermiştir. Regresyon analizi sonuçlarına
göre yağ oranı için Soxhlet ekstraksiyonu ve soğuk ekstraksiyon ile elde edilen
sonuçlar arasında doğrusal ve yüksek önemli bir ilişki olduğu gözlemlenmiştir.
Karotenoid içeriği bakımından karşılaştırılan bu üç yöntem arasındaki regresyon
katsayılarının oldukça düşük çıktığı gözlemlenmiştir. Bu bulgular farklı
ekstraksiyon yöntemleri ile elde edilen yağlar üzerinden yapılan analizler
sonucu bulunan değerlerin karotenoid içeriği tahminlerinde birbirleri yerine
kullanılmasının doğru olmadığını göstermektedir.
Application of Landsat 8 Satellite Image – NDVI Time Series for Crop Phenology Mapping: Case Study Balkh and Jawzjan Regions of Afghanistan

Published: May 2019

In this article, it was targeted to reveal the
variations of NDVI which may represent the phenological stages of agricultural
crops derived from Landsat 8 imagery from the start to end of growing seasons
which eventually influence the final yields. An effective method was developed
to map seasonal phenological variations of crops over large geographic regions
using 16-day Landsat 30 m resolution NDVI time series data obtained from USGS.
The Google Earth Engine (GEE) platform was used for processing the Landsat 8
data. The areas with cloud cover and cloud shadows were masked out, filled by
no data and smoothing double logistic filter was fitted on the time series of
the reflectance values. Phenological metrics extracted from the NDVI time
series were obtained by the TIMESAT software. Seasonal data were extracted for
growing seasons of the years of 2015 and 2016. The phenology maps were created
for study area.

Decision-making and subjective evaluation are two important aspects that characterizes the involvement of an organization in tender process. Moreover, selection of the right project to bid for is a principal feature of business success. The study aims to investigate the behavioral differences of Saudi construction contractors toward internal and external factors based on the process of modelling the bidding decisions. A quantitative research design is used to investigate the behavioral differences of 97 contractors recruited from construction industry of Saudi Arabia. A questionnaire was distributed among the respondents that would help in identifying the significant level of factors affecting the bid or no bid decision. The impact of internal and external factors on the bidding decisions was evaluated using one-way ANOVA analysis. The results have shown a significant and positive effect of internal and external factors on the bid or no bid decision; including job start time, work capital requirement, availability of qualified human resources, bidding methods, bidding document price, project supervision procedure and etc. The study has helped in establishing a better understanding toward the behavioral differences of contractors with respect to the bidding decisions.
ANALISA EFEK JAHN TELLER TERHADAP STRUKTUR KRISTAL SENYAWA DELAFOSSITE AGCR1-XNIXO2 (0,01 ≤ X ≤ 0,04)

Telah dilakukan visualisasi struktur kristal senyawa delafossite AgCrO2 yang didoping doping ion Ni2+  menggunakan software Crystal MakerX 10.4. Input Data dengan Grup Ruang Nomor 166 dan Tabel Wick Offnya diperoleh dari American Mineralogist Crystal Structure Database (AMCSD). Berdasarkan hasil visualisasi tampak bahwa terjadi peningkatan nilai parameter kisi pada arah sumbu z (parameter kisi c) dan volume sel kristal. Fenomena ini dapat dijelaskan menggunakan efek Jahn – Teller. Jika kita meninjau menurut konfigurasi energinya, ion Cr3+ memiliki konfigurasi (t2g)3(eg)0 yang mana orbital t2g , 3 elektron 3d yang boleh mengisi orbital dxy sedangkan ion Ni2+ memiliki konfigurasi (t2g)6(eg)2 yang mana orbital eg boleh diisi oleh 2 elektron 3d yang menempati dz2.. Misalkan ion Cr3+ yang digantikan terletak pada orbita dxy digantikan oleh ion Ni2+ yang memiliki orbital dz2 sehingga 6 atom oksigen pada bagian oktahedral CrO6 akan bergerak menjauhi ion Cr3+ sehingga 2 atom oksigen pada dumbell Ag - O sepanjang sumbu z juga akan ikut berpindah. Akibatnya terjadi distorsi secara spontan sepanjang sumbu x, y, dan z menyebabkan terjadinya peningkatan parameter kisi. Adanya distorsi ini mengakibatkan hilangnya degenerasi sehingga senyawa lebih stabil.
PENGARUH SUNK COST IMPORT ENTRY DAN IMPORT SPILLOVER TERHADAP KEPUTUSAN MENGIMPOR BAHAN BAKU PADA PERUSAHAAN MANUFAKTUR DI INDONESIA

Abstract : Regardless the benefits of imported inputs, uncertainties in foreign markets and highly sunk inisial costs (e.g. cost of searching foreign suppliers), become a barrier to entry for most of firm and causing persistent to use the imported input. However, the sunk cost entry give the information insentives about import activities for the importer. So, when importers are neighboring in a location, they pottentially induce knowledge spillovers to the other firms. The more importers at that location, the more knowledge is spread, so that it can potentially reduce initial import costs and increase the prospensity to import for other neighbors. This study uses dynamic panel data of Indonesian manufacturing firms from 2007 until 2015, to examine the determinant of decision to import, especially sunk cost and spillovers. The results of the GMM difference estimation indicate that firm who imported last year and two years earlier more likely to import input this year, both for domestic and foreign firms. This study also found a positive correlation between probability of importing input and the number of importer in the same region regardless of their industrial affiliation. However, this finding is limited only to indegenous firm which generated by agglomeration of indegenous importers.Keywords: decision to import, sunk cost of import entry,  spillover, dynamic panel dataAbstrak : Terlepas dari manfaat imported input, ketidakpastian di pasar luar negeri dan biaya inisial yang tinggi dan sunk mencegah sebagian besar perusahaan untuk mengimpor dan menyebabkan perusahaan persisten mengimpor bahan baku.  Namun, sunk cost entry tersebut sarat akan informasi terkait aktivitas impor, sehingga berpotensi menimbulkan knowledge spillover ketika importir berdekatan di satu lokasi tertentu. Semakin banyak importir di lokasi tersebut, semakin banyak informasi yang tersebar, sehingga dapat mengurangi biaya inisial impor dan meningkatkan kecenderungan untuk mengimpor bagi perusahaan lain. Penelitian ini mengunakan data panel dinamis perusahaan manufaktur di Indonesia (2007 - 2015) untuk mempelajari determinan keputusan impor bahan baku, terutama sunk cost entry dan import spillover. Hasil estimasi GMM difference menunjukkan perusahaan yang mengimpor satu dan dua tahun sebelumnya cenderung akan mengimpor bahan baku tahun ini, baik bagi perusahaan domestik maupun asing. Penelitian ini juga menemukan adanya hubungan positif antara keputusan impor dengan jumlah importir yang berada di satu kabupaten baik di industri yang sama maupun berbeda. Namun, temuan tersebut terbatas hanya terjadi bagi perusahaan domestik yang berasal dari aglomerasi importir domestik.Kata kunci: keputusan untuk impor, sunk cost import entry, spillover, data panel dinamis
