Sociología sistémica de lo político. Lineamientos de un programa de investigación
Authors: Estrada Saavedra Marco
Published: October 2018

En este artículo se presenta un esbozo de una sociología sistémica de lo político en desarrollo. Se parte de la problematización de las dimensiones políticas de la acción colectiva y los movimientos sociales como convencionalmente son entendidas por las correspondientes teorías de alcance medio. Ante la simplificaciones de éstas últimas, se explora la posibilidad de complejizar nuestro entendimiento del fenómeno mediante la revisión de las discusiones contemporáneas en torno a lo político en la filosofía política contemporánea. Un concepto de lo político proveniente de la filosofía debe ser reformulado, sin embargo, para hacerlo apto para la investigación empírica en las ciencias sociales. Una vía prometedora para lograr este objetivo consiste en integrarlo a la descripción del sistema político como su contraparte y reformularlo de acuerdo con la gramática conceptual de la teoría de sistemas sociales de Niklas Luhmann. La ganancia en abstracción y generalización de lo político obtenida de esta manera se enriquece además con los aportes metodológicos de la denominada antropología del Estado. La sociología sistémica de lo político es propuesta como un modelo conceptual y analítico que sirva para las pesquisas empíricas y la aprehensión de las diferencias sociohistóricas de lo político y las compleja y conflictivas relaciones entre Estado y sociedad en sociedades como las latinoamericanas.

Published: October 2018

Aims

A global outbreak of Mycobacterium chimaera infections following cardiac surgery and linked to contaminated heater-cooler units (HCUs) is currently ongoing. Neither the status of this outbreak in Italy nor the mitigation strategies adopted by adult cardiac surgery units (ACSUs) are currently known. In 2017, the Italian Society of Cardiac Surgery launched a national survey among the Italian ACSU to shed some light on this issue.

Methods

In Italy, there are 90 ACSUs across 20 regions. From May to November 2017, these ACSUs were surveyed collecting data on patients diagnosed with MC infections, ACSU workload, HCU models in use and control measures adopted in the operatory room.

Results

The response rate was 87.8%. The median number of cardiac procedures at each ACSU was 450/year [interquartile range (IQR) 350–650 procedures/year], and nationally, the number of procedures/year exceeded 40k. In Italy, seven patients with M. chimaera infections following cardiac procedures have been reported since 2015: all had aortic or valvular surgery as the first procedure; the median latency between the first operation and the infection was 2 years (IQR 2–3.25). Mortality for patients requiring redo cardiac surgery was 50%. M. chimaera infections risk was 0.4–1 patient every 1000 cardiac procedures. The most common HCU model in Italy is the 3T HCU (70.9%). The most common control measures adopted included implementing new HCU disinfection protocols, using sterile or filtrated water in the HCU and displacing HCU fans away from the patient: HCU replacement and microbiology testing were instead infrequent.

Conclusion

In Italy, the risk of contracting M. chimaera infections and the mortality reported are in line with other European countries, but significant heterogeneity exists on the mitigation strategies adopted to prevent further M. chimaera inoculations, suggesting the development of national guidelines.

Authors: Memon Sumera , Ishak Mohd. Sobhi Bin , Hamid Norsiah Binti Abdul
Published: October 2018

Young people are often characterized as apathetic and disconnected from the political world. Undoubtedly, their low rate of participation in general elections has increased concerns amongst researchers as well as policy makers. This concern has stimulated researchers to explore the factors which weaken or discourage youth engagement in political activities. Thus, this study assesses the role of family communicative environment, peer group communicative environment and school communicative environment as types of political socialization agents of political participation of youths. A cross-sectional survey was conducted among 288 social science students in Pakistan. Questionnaires were used to collect data and the collected data was analyzed using SPSS 23. The findings revealed that family communicative environment and peer group communicative environment positively influence the political participation of youths. However, school communicative environment was found to influence political participation negatively. This study provides an empirical justification for the potential of family and peer group as agents of political socialization for enhancing political activities among youth in Pakistan.

Many theories explain the definition of beauty; it is said that it is seen from their outer beauty and inner beauty, however many Indonesian women still have a strong perception that beautiful women are the ones with bright skin, long hair and slim.Clean & Clear products try to see the meaning of beautiful from its different point of view. It should not be white, long-haired and slim, therefore Clean & Clear ads show female models with different perception of 'beautiful' women in general. This study aims to determine the meaning of outer beauty and inner beauty in Clean & Clear ads version of '1000 tribes Indonesia, different skin colors'. The method used in this research is qualitative research by using semiotics analysis Roland Barthes by focusing on the sign of denotation, connotation, and myth based on critical paradigm. Data collection techniques used here are Clean & Clear ads version of '1000 Indonesian tribe, different skin color as the primary data and reference book, paper and article as the secondary data. The result of study shows that Clean & Clear ads try to highlight inner beauty through high confidence, a loose smile showing the happiness of women who are seen different from their outer beauty, they do not have bright skin and long black hair. Otherwise in this ad, researchers see there is one component of beauty still maintained by Clean & Clear, that is about a slim body. It is seen from the nine female models featured in this ad, all of them are slim. As we all know that many women who are not slim, they are still obsessed to look beautiful.

A Probabilistic Molecular Fingerprint for Big Data Settings
Authors: Probst Daniel , Reymond Jean-Louis
Published: October 2018

Background: Among the various molecular fingerprints available to describe small organic molecules, ECFP4 (extended connectivity fingerprint, up to four bonds) performs best in benchmarking drug analog recovery studies as it encodes substructures with a high level of detail. Unfortunately, ECFP4 requires high dimensional representations (≥1,024D) to perform well, resulting in ECFP4 nearest neighbor searches in very large databases such as GDB, PubChem or ZINC to perform very slowly due to the curse of dimensionality. Results: Herein we report a new fingerprint, called MHFP6 (MinHash fingerprint, up to six bonds), which encodes detailed substructures using the extended connectivity principle of ECFP in a fundamentally different manner, increasing the performance of exact nearest neighbor searches in benchmarking studies and enabling the application of locality sensitive hashing (LSH) approximate nearest neighbor search algorithms. To describe a molecule, MHFP6 extracts the SMILES of all circular substructures around each atom up to a diameter of six bonds and applies the MinHash method to the resulting set. MHFP6 outperforms ECFP4 in benchmarking analog recovery studies. Furthermore, MHFP6 outperforms ECFP4 in approximate nearest neighbor searches by two orders of magnitude in terms of speed, while decreasing the error rate. Conclusion: MHFP6 is a new molecular fingerprint, encoding circular substructures, which outperforms ECFP4 for analog searches while allowing the direct application of locality sensitive hashing algorithms. It should be well suited for the analysis of large databases. The source code for MHFP6 is available on GitHub (https://github.com/reymond-group/mhfp).
Oxygen-Oxygen Bond Cleavage and Formation in Co(II) Mediated Stoichiometric O2 Reduction via the Potential Intermediacy of a Co(IV) Oxyl Radical
Authors: Nurdin Lucie , Spasyuk Denis M. , Fairburn Laura , Piers Warren , Maron Laurent
Published: October 2018

Diprotonation of a remarkably stable, toluene soluble cobalt peroxo complex supported by a neutral, dianionic pentadentate ligand leads to facile O-O bond cleavage and production of a highly reactive Co(IV) oxyl cation intermediate that dimerizes and releases O2. These processes are relevant to both O2 reduction and O2 evolution and the mechanism was probed in detail both experimentally and computationally.
Photochemical and Electrochemical Reduction of Carbon Dioxide Catalyzed by a Polyoxometalate-Organic Photosensitizer Complex
Authors: Dey Chandan , Neumann Ronny
Published: October 2018

A manganese substituted Anderson type polyoxometalate, [MnMo6O24]9-, tethered with an anthracene photosensitizer was prepared and used as catalyst for CO2 reduction. The polyoxometalate-photosensitizer hybrid complex, obtained by covalent attachment of the sensitizer to only one face of the planar polyoxometalate, was characterized by NMR, IR and mass spectroscopy. Cyclic voltammetry measurements show a catalytic response for the reduction of carbon dioxide, thereby suggesting catalysis at the manganese site on the open face of the polyoxometalate. Controlled potentiometric electrolysis showed the reduction of CO2 to CO with a TOF of ~15 sec-1. Further photochemical reactions showed that the polyoxometalate-anthracene hybrid complex was active for the reduction of CO2 to yield formic acid and/or CO in varying amounts dependent on the reducing agent used. Control experiments showed that the attachment of the photosensitizer to [MnMo6O24]9- is necessary for photocatalysis.

Published: October 2018

In the review article, the problem of optimization of local hormone therapy of urogenital disorders in women from the perspective of evidence based medicine on the basis of the modern multifactorial concept of genito-urinary menopausal syndrome (GUMS), which implies an important pathogenetic role of not only the age-related estrogen deficiency, but also the deficiency of other sex hormones in the pathogenesis of disorders urogenital tract in women in peri- and postmenopausal women. The important role of bioidentical progesterone as a metabolically active hormone possessing not only classical (reproductive) physiological effects in the body of a woman but also a whole spectrum of nonclassical (nonproductive) effects that demonstrate the pathogenetic justification of the expediency of topical administration of preparations containing a bioidentical analog of natural progesterone within the framework of a complex and personalized treatment of various clinical manifestations of GUMS, especially in women with sop favoring endogenous progesterone deficiency, which can occur chronologically after the 35 years preceding the age of estrogen deficiency. The comparative characteristics of the available dosage forms of progesterone delivery are demonstrated, and the pathogenetic expediency and effectiveness of the additional prescription of topical progesterone to local estrogen therapy in the most common clinical variants of the GUMS is demonstrated using the latest research.

Development of a prediction classifier for the early diagnosis of liver cancer
Authors: Wu Di , Cao Jianhua , Li Wei , Wang Xin
Published: October 2018

Hepatocellular carcinoma (HCC) is the second cause of cancer-related death worldwide, and the incidence rate of liver cancer has continuously increased, with approximately 750,000 new diagnosed cases each year. Especially in China, both the incidence and mortality rate of HCC have been ranked second among all cancers. Importantly, HCC mortality rate is similar to its incidence rate, indicating that most patients with liver cancer die from HCC. In clinical practice, liver cancers are usually diagnosed by detecting alpha-fetoprotein (AFP) and abdominal ultrasound. However, abnormal AFP is usually detected at late stages of liver cancer, in which most patients are refractory to surgery, radiotherapy and chemotherapy. Moreover, AFP is not detectable in some liver cancer patients. In this study, we aimed to establish an alternative diagnostic method for liver cancer patients by analyzing hidden patterns and relationships among multiple specific markers of liver cancers. By building a predictive classification of liver cancer and the relationship between different markers, a support vector machine (SVM) classifier was developed. Our SVM classifier integrated 22 specific markers. Our results revealed that the input of these 22 markers into the classifier could accurately determine the exitence of HCC in a patient. Our established SVM classifier may achieve the early prediction of liver cancer, thereby improving the accuracy of diagnosis and treatment of live cancer patients.

Published: October 2018

Наші нанотехнології й наномедицина швидко розвиваються в пошуках нових ліків. Препарати на основі наночастинок срібла (НЧС) серед них займають лідируюче становище. Стають актуальними дослідження, спрямовані на оцінку впливу різних доз і розмірів НЧС на жіночу репродуктивну систему у тварин. Такі дослідження нададуть нові дані, які будуть сприяти більш повному розумінню механізмів дії НЧС в лабораторних умовах, а також забезпечать успішний перехід нанотехнологій срібла в клініку. Отже, вплив НЧС на клітини і тканини ссавців вимагає подальшого вивчення.
Мета цього дослідження – оцінити вплив внутрішньовенного введення наночастинок срібла на функціональний стан яєчника у мишей, а саме на ооцити (їх кількість і мейотичене дозрівання) і на клітини їх фолікулярного оточення (кількість живих і з морфологічними ознаками апоптичної і некротичної загибелі) в умовах експериментального гломерулонефриту.
Експериментальний гломерулонефрит у мишей отримували імунізацією білих лабораторних мишей першого покоління суспензією антигену нирки, отриманої від попереднього покоління. Уведення проводили таким чином: антиген нирки − внутрішньобрюшинно три рази 1 раз в день; процедуру повторювали через три тижні, один раз внутрішньобрюшинно тією самою дозою (10 мкл суспензії на 10 г ваги). Наночастки срібла  (30 нм) - внутрішньовенно три рази: 1 раз в день за 1 годину до імунізації тварин суспензією антигену нирки; а також через три тижні в тій самій дозі (2 мг / кг).
Встановлено, що кількість ооцитів, що відновлювали мейоз in vitro у тварин в умовах експериментального гломерулонефриту, зменшується, порівнянні з такою кількістю у контрольних тварин; в умовах введення НЧС не виявлено пригнічення мейотичного дозрівання ооцитів; уведення НЧС в умовах експериментального гломерулонефриту збільшує кількість ооцитів, що відновлюють мейоз in vitro, порівняно з такими величинами в контролі і в умовах експериментального гломерулонефриту, а також збільшується кількість живих клітин і зменшується кількість клітин із морфологічними ознаками апоптозу в фолікулярному оточенні ооцитів.

Panel data describes a condition in which there are many observations with each observation observed periodically over a period of time. The observation clustering context based on this data is known as Clustering of Time Series Data. Many methods are developed based on fluctuating time series data conditions. However, missing data causes problems in this analysis. Missing data is the unavailability of data value on an observation because there is no information related to it. This study attempts to provide an alternative method of clustering observations on data with time series containing missing data by utilizing correlation matrices converted into Euclid distance matrices which are subsequently applied by the hierarchical clustering method. The simulation process was done to see the goodness of alternative method with common method used in data with 0%, 10%, 20% and 40% missing data condition. The result was obtained that the accuracy of the observation bundling on the proposed alternative method is always better than the commonly used method. Furthermore, the implementation was done on the annual gini ratio data of each province in Indonesia in 2007 to 2017 which contained missing data in North Kalimantan Province. There were 2 clusters of province with different characteristics.

The median direction is one of central tendency of circular data. The estimation process usually requires information about sampling distribution of statistic that want to be used as a parameter estimate. Theoretically, sampling distribution derived from population distribution. But, it is not easy to get sampling distribution of median although the population distribution is known.  When the sampling distribution cannot be derived easily from population distribution, the bootstrap method can be an alternative to handle it. This study wants to evaluate the effect of increasing concentration parameter to the performance of bootstrap confidence interval estimation for median direction through simulation study. Three methods were used to estimate the interval  which are equal-tailed arc (ETA), symmetric arc (SYMA), and likelihood-based arc (LBA). The most important criterion to evaluate them were true coverage and interval width. The simulation results that in general, the increasing of concentration parameter followed by  more narrow interval. For small concentration parameter (k<1), all methods give unstable true coverage and interval width. The authors also identify that those three methods produce intervals with identical width when the parameter concentration is 20 or more. In terms of coverage and interval width, the best method was ETA.

Published: October 2018

Relationships between planting time and yield as well as profitability of growing potato were investigated in Cikajang, Garut, based on water balance analysis and survey to potato farmers of the area. In general, there were three planting dates namely December-January, April-May and August-September. Yield and profitability of growing potato for planting time of August-September was less compared to the other two planting times due to lack of soil-water availability related to less rainfall as well as its high rainfall variability during dry season (coefficient of variation = 133%). Yields of potato for planting times December-January, April-May and August-September were (21.4 + 3.4), (20.5 + 3.5) and (16.9 + 2.2) tonnes/ha, respectively.Relationships between planting time and yield as well as profitability of growing potato were investigated in Cikajang, Garut, based on water balance analysis and survey to potato farmers of the area.

Published: October 2018

Indonesia merupakan salah satu negara dengan keanekaragaman tanaman buah tropika yang cukup tinggi. Keanekaragaman tanaman buah tropika tersebut merupakan satu tantangan dalam melakukan identifikasi. Identifikasi tanaman dapat dilakukan berdasarkan buah, bunga, maupun daun. Identifikasi berdasarkan daun merupakan identifikasi yang lebih mudah dilakukan karena daun akan ada sepanjang masa, sedangkan bunga dan buah mungkin hanya ada pada waktu tertentu. Identifikasi tanaman menggunakan daun dapat dilakukan berdasarkan bentuk, tekstur, maupun warna citra daun tersebut. Pada penelitian ini, ekstraksi fitur gray level co-occurrence matrix (GLCM) dari tekstur citra permukaan daun buah tropika digunakan sebagai input dari pelatihan Jaringan syaraf tiruan untuk proses identifikasi. Secara keseluruhan, pengujian dengan menggunakan hidden neuron sebanyak 7 menghasilkan hasil akurasi terbaik, yaitu 90%.

Published: October 2018

Identifikasi jenis kayu di Indonesia pada umumnya dilakukan secara manual, dengan cara memperhatikan pori kayu pada daerah penampang kayu menggunakan kaca pembesar atau mikroskop dengan pembesaran minimal 10 kali. Teknik komputerisasi belum banyak dilakukan terutama karena kurangnya penelitian di bidang ini dan sulitnya mendapatkan database kayu. Penelitian ini bertujuan mengembangkan sebuah sistem untuk mengklasifikasikan 4 jenis kayu yang diperdagangkan di Indonesia dengan metode support vector machine (SVM) berbasis citra. Teknik ekstraksi ciri yang digunakan adalah two-dimensional principal component analysis (2D-PCA). Sistem ini dapat mengidentifikasi kayu dalam waktu singkat sehingga mempercepat proses identifikasi jenis kayu. Hasil klasifikasi dari 120 kali percobaan dengan menggunakan 96 data citra dengan 4 jenis kayu menunjukkan akurasi terbaik sebesar 95.83% pada kernel Polinomial.
