Hoàn thiện cơ chế đảng lãnh đạo, nhà nước quản lý, nhân dân làm chủ ở Việt Nam - Từ tiếp cận lý thuyết hệ thống xã hội
Authors: Nguyễn Đình Tấn
Published: November 2017

Lý thuyết hệ thống xã hội là một trong các lý thuyết quan trọng của xã hội học. Khả năng ứng dung nghiên cứu của nó là rất lớn. Thuyết hệ thống nhấn mạnh vào chức năng cân bằng, ổn định, trật tự của xã hội; nó cũng đồng thời đòi hỏi  mọi thành viên của xã hội phải phát huy tính chủ động của bản thân trong việc thực hiện các vai trò của mình song cũng đồng thời phải biết tuân thủ những đòi hỏi chung của cả hệ thống hệ thống. Thuyết hệ thống cũng nhấn mạnh vào việc mỗi cá  nhân phải thực hiện không chỉ một vai trò mà là một tập hợp các vai trò (cả theo chiều “ngang” và cả theo chiều “dọc”). Một trong những nghiên cứu ứng dụng lý thuyết có ý nghĩa là việc vận dụng lý thuyết tiếp cận hệ thống vào việc hoàn thiện cơ chế Đảng lãnh đạo nhà nước quản lý nhân dân làm chủ. Đó là việc coi xã hội là một hệ thống lớn; trong đó bao gồm nhiều hệ thống con. Mỗi hệ thống con có những chức năng khác nhau song đồng thời lại có cùng  một chức năng chung của hệ thống.
Điều kiện hình thành và phát triển mô hình liên kết nghiên cứu khoa học với sản xuất và đào tạo ở Viện Hàn lâm Khoa học và Công nghệ Việt nam
Authors: Phạm Tuấn Huy
Published: November 2017

Khi mới thành lập, Viện Khoa học Việt Nam (nay là Viện Hàn lâm Khoa học và Công nghệ Việt Nam) hoạt động theo mô hình Viện Hàn lâm Khoa học Liên Xô nên có sự phân li giữa nghiên cứu khoa học với sản xuất và đào tạo. Trong 40 năm qua Viện đã từng bước khắc phục sự phân ly này, nhiều mô hình liên kết khoa học với sản xuất và đào tạo đã được thực hiện.

Tuy nhiên, phát triển Viện Hàn lâm phù hợp với tình hình hội nhập quốc tế cần những điều kiện để hình thành và phát triển các mô hình liên kết giữa nghiên cứu khoa học với sản xuất và đào tạo. Đó là những điều kiện quản lý vĩ mô và nỗ lực của Viện Hàn lâm cũng như các Viện chuyên ngành.

Fronteras, arquitectura y consumo: hacia una heterotopía de la ciudad
Authors: Useche López Camilo
Published: November 2017

Este artículo intenta hacer una reflexión desde los estudios fronterizos de la ciudad y el espacio, donde el consumo y el uso urbano son acaparados constantemente por el capital. Sin embargo, la ciudad crea dentro de sí fronteras en las que se elaboran y se retransmiten deseos y conjeturas, y allí todo puede ser posible. En esta heterotopía, como lo llamaría Foucault, se reconstruyen las ciudades cotidianamente, ese espacio donde muchas veces la arquitectura pasa a ser consumo visible en la urbe.

Arte y desobediencia civil
Authors: Ballesteros Peluffo Gilma Liliana
Published: November 2017

El arte ha permitido colocar en el debate público cuestiones políticas, ha roto esquemas convencionales, ha cuestionado la construcción de la sociedad y se ha manifestado para protestar y denunciar. Podemos observar en autores como Goya, Picasso y Rivera su inconformidad por la guerra, la pobreza y la desigualdad, y en autores como Chagall y Rothko un llamado a la conciencia y la reflexión.De esta manera, éste artículo hace un breve repaso por las obras de pintura de una selección de autores, destacando el arte como un instrumento pacífico que conduce a la reflexión, que crítica e introduce transformaciones en las mentalidades. Igualmente, se señalan los debates políticos suscitados en la época del artista y su contribución a la transformación política, convirtiendo el arte en una invitación sublime a desobedecer civilmente.

Una mirada praxeológica a la arquitectura del conocimiento en las organizaciones
Authors: Juliao Vargas Carlos G.
Published: November 2017

En su obra titulada Architectures of Knowledge, Amin y Cohendet (2004) proponen una aproximación al modo en que se produce, almacena, intercambia, transmite y se recupera conocimiento en las empresas, y más allá, en las organizaciones humanas, dando prelación a las prácticas incorporadas, socialmente inscritas y ancladas en los artefactos. Esto los lleva a reconstruir la teoría de la movilización de los conocimientos colectivos. En el centro de esta nueva conceptualización ubican la noción de comunidad, concebida como el lugar de realización de las prácticas intersubjetivas y sociales. Para hacerlo, el libro ofrece una visión epistemológica rica y bien articulada que se puede calificar como praxeológica, así como una metodología basada en una etnografía de los flujos de conocimientos en las organizaciones. Desde las ciencias humanas se propone aquí una lectura de esta nueva conceptualización, resaltando el hecho de la proximidad que existe entre sus raíces epistemológicas (pragmatismo americano, enaccionismo de Maturana y Varela, teoría de la acción situada, socioculturalismo y movimiento de los estudios sociales de la ciencia y la tecnología) y una serie de trabajos que consideran los procesos cognoscitivos como prácticas inscritas socialmente más que como procesos de tratamiento de la información.

Even if social accounting have been found centuries ago, their development is increased when people aware not only that their action is affected in economy wealth, it is also influenced their social, environmental, and sustainability development. Accounting is trying to measure this externalities cost. Some are skepticism with the effort since in reducing these externalities of environmental destructions; it will not support the notion of social contract. Likewise, spiritual accounting is also trying to concern for others but in a spiritual point of view. This new development in accounting is a challenge for accounting profession in a way how they have to behave. Accountants not only have to obey to accounting profession code of ethics, they also have to practice accounting in their socio-spiritual manner.

Published: November 2017

El sistema estuarino-lagunar Marismas Nacionales (México) es un Sitio de Importancia Internacional designado por la Red Hemis­férica de Reservas de Aves Playeras. La Avoceta americana (Recurvirostra americana) es una de las aves playeras invernantes más numerosas en el área. Sin embargo hay poca información sobre su estancia invernal en el sitio, a pesar de que el sitio fue decretado Reserva de la Biosfera. En este estudio determinamos, a través de trayectos y muestreo de barrido durante el invierno (noviembre-marzo), la distribución y abundancia en las Marismas Nacionales (2010-2011), así como densidad y estructura de población en uno de los sectores de la Reserva de la Biosfera durante 2011-2013. Estimamos en 26,000 individuos la población invernante de Avoceta Americana en la Reserva de la Biosfera (5.7% de la población mundial), pero aproximadamente el 36% de la población invernante la observamos en sitios fuera del polígono de la reserva. La evidencia sugiere que la migración de primavera comenzó durante las primeras semanas de marzo. Hemos observado alguna segregación espacial entre los sexos, pero nuestros resultados, aunque válidos, no son concluyentes debido a la dificultad de identificación de los sexos en algunos individuos. A pesar de los cambios en estos humedales, la población invernante de Avoceta americana ha permanecido relativamente estable en los últimos veinte años. Por lo que Marismas Nacionales sigue siendo un humedal clave para la Avoceta americana en Norteamérica.

Place, Motion, and Guilt in Wilhelm Raabe’s Stopfkuchen
Authors: Lyon John B.
Published: November 2017

Wilhelm Raabe’s novel, Stopfkuchen (1890) highlights inescapable guilt, guilt that is both bound to specific places and that can travel great distances. The themes of guilt, place, and motion are interconnected in this novel, and the novel marks a modern shift in the understanding of these themes. It traces an emerging awareness of both the narrator’s individual guilt in a more traditional sense and the collective guilt of his town and of German culture in a more modern sense. This guilt is both connected to place and dissociated from it, suggesting both a pre-modern connection to place and a sense of displacement typical of modernity. By the end of the novel we find a sense of inescapable guilt that both resides in specific places and compels the guilty toward motion. It makes specific places unheimlich even as it extends across the globe.
Ester-Based Pyridinium Gemini Surfactants as Novel Inhibitors for Mild Steel Corrosion in 1 M HCl Solution
Authors: Mobin Mohammad , Aslam Ruby
Published: November 2017

The corrosion inhibition ability of ester based pyridinium Gemini surfactants (GS) with different hydrophobic character (14-Py and 16-Py) towards mild steel (MS) in 1 M HCl solution was investigated at various concentrations and temperatures (303–333 K). Potentiodynamic polarization, electrochemical impedance spectroscopy, weight loss, surface analysis (SEM/EDAX and AFM) and FT-IR were combined to investigate the corrosion inhibition behaviour of the surfactants. 14-Py and 16-Py were found to be efficient, mixed type inhibitors. The inhibition efficiencies increased with increasing concentration, hydrophobicity and solution temperature. The existence of a protective film of the adsorbed inhibitors on the MS surface was confirmed by SEM/EDX/AFM.

Authors: Wang Tiantian , Zhou Yuming , Yao Qingzhao , Zhang Ao , Li Jun , Chen Yiyi , Zhu Xinye , Chen Xiangnan , Nan Qiuli , Zhang Mingjue , Wu Wendao , Sun Wei
Published: November 2017

A novel double-hydrophilic copolymer (acrylic acid-isoprenyl polyethoxy carboxylate, AA-TPEL) is synthesized and the structural properties are identified by FT-IR, 1HNMR and GPC analyses. The inhibitory behavior of the copolymer is determined by using a static scale inhibition method. It is shown that AA-TPEL exhibits an excellent ability to control the formation of CaCO3 scale with an inhibition efficiency of 88.67 % at the 8 mg L–1, and it still maintains a superior efficiency even at increasing solution temperature, pH, and Ca2+ concentration. Weight loss test, potentiodynamic polarization and electrochemical impedance spectroscopy are applied to investigate the inhibition efficiency on mild steel corrosion. All measurements show that, AA-TPEL acts as an efficient corrosion inhibitor and also displays a superior ability to prevent the corrosion of mild steel with approximately 83.21 % inhibition efficiency at the low level of 10 mg L–1. Scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) are used to characterize the surface morphology of CaCO3 and steel.

The typology follows the Multi-dimensional framework proposed by Biber (1989) , which defines text types as linguistic constructs derived from dimensions of variation, or co-occurring sets of linguistic characteristics that underlie register variation in a particular language or language variety. The text types were identified following a cluster analysis that took as input the dimension scores for each text on each of the six dimensions of variation. The clusters were interpreted as nine text types, each representing a typical textual configuration found in Brazilian Portuguese.

This paper presents a theoretical approach for lowering the outlet flow ripple of a crescent pump by applying a tandem crescent pump consisting of two gear pairs with an index angle between them. The outlet flow of the tandem pump is obtained by summing the flow produced by the two gear pairs, and the flow ripple of the tandem pump can be attenuated by properly selecting the design parameters in terms of the index angle and the displacement ratio between the two gear pairs. A lumped parameter model is presented for evaluating the crescent pump’s flow ripples, and experiments were performed on a single crescent pump to validate the model from the aspects of the steady-state flow-pressure characteristics and the outlet pressure ripples. In this way, the main causes of the flow ripple could be identified by comparing the kinematic flow with the actual flow evaluated by the model. Additionally, simulation results suggested that a tandem pump with an index angle of 13.85° and displacement ratio of 0.5 could lead to a more than 45% decrease in the outlet flow ripple than a single pump with the same displacement in a wide range of operating conditions.

In the diagnosis of neurological diseases and assessment of brain function, entropy measures for quantifying electroencephalogram (EEG) signals are attracting ever-increasing attention worldwide. However, some entropy measures, such as approximate entropy (ApEn), sample entropy (SpEn), multiscale entropy and so on, imply high computational costs because their computations are based on hundreds of data points. In this paper, we propose an effective and practical method to accelerate the computation of these entropy measures by exploiting vectors with dissimilarity (VDS). By means of the VDS decision, distance calculations of most dissimilar vectors can be avoided during computation. The experimental results show that, compared with the conventional method, the proposed VDS method enables a reduction of the average computation time of SpEn in random signals and EEG signals by 78.5% and 78.9%, respectively. The computation times are consistently reduced by about 80.1~82.8% for five kinds of EEG signals of different lengths. The experiments further demonstrate the use of the VDS method not only to accelerate the computation of SpEn in electromyography and electrocardiogram signals but also to accelerate the computations of time-shift multiscale entropy and ApEn in EEG signals. All results indicate that the VDS method is a powerful strategy for accelerating the computation of entropy measures and has promising application potential in the field of biomedical informatics.

This paper presents a freeway driving cycle (FDC) construction method based on traffic information. A float car collected different type of roads in California and we built a velocity fragment database. We selected a real freeway driving cycle (RFDC) and established the corresponding time traffic information tensor model by using the data in California Department of Transportation performance measure system (PeMS). The correlation of road velocity in the time dimension and spatial dimension are analyzed. According to the average velocity of road sections at different times, the kinematic fragments are stochastically selected in the velocity fragment database to construct a real-time FDC of each section. The comparison between construction freeway driving cycle (CFDC) and real freeway driving cycle (RFDC) show that the CFDC well reflects the RFDC characteristic parameters. Compared to its application in plug-in electric hybrid vehicle (PHEV) optimal energy management based on a dynamic programming (DP) algorithm, CFDC and RFDC fuel consumption are similar within approximately 5.09% error, and non-rush hour fuel economy is better than rush hour 3.51 (L/100 km) at non-rush hour, 4.29 (L/km) at rush hour)). Moreover, the fuel consumption ratio can be up to 13.17% in the same CFDC at non-rush hour.
A New Reactive-Power Sharing Scheme for Two Inverter-Based Distributed Generations with Unequal Line Impedances in Islanded Microgrids
Authors: Kim Jae-Hyuk , Lee Yoon-Seok , Kim Hyun-Jun , Han Byung-Moon
Published: November 2017

This paper proposes a new reactive-power sharing scheme to reduce the circulating current when two inverter-based distributed generations (DGs) operate in parallel through unequal line impedances in an islanded microgrid. If the terminal voltages of the two DGs are not equal due to the unequal line impedances, a circulating current due to reactive-power unbalance occurs, which increases system loss. The proposed droop control compensates the terminal voltage difference to reduce the circulating current by considering a feed-forward path of the line voltage drop. The feasibility of the proposed droop control was first verified through computer simulations, and then experiments with a hardware set-up in the lab. The experimental results were compared with the simulation results to confirm the feasibility of the proposed droop control.

The Small and the Dead: A Review of Ancient DNA Studies Analysing Micromammal Species
Authors: Woods Roseina , Marr Melissa , Brace Selina , Barnes Ian
Published: November 2017

The field of ancient DNA (aDNA) has recently been in a state of exponential growth, largely driven by the uptake of Next Generation Sequencing (NGS) techniques. Much of this work has focused on the mammalian megafauna and ancient humans, with comparatively less studies looking at micromammal fauna, despite the potential of these species in testing evolutionary, environmental and taxonomic theories. Several factors make micromammal fauna ideally suited for aDNA extraction and sequencing. Micromammal subfossil assemblages often include the large number of individuals appropriate for population level analyses, and, furthermore, the assemblages are frequently found in cave sites where the constant temperature and sheltered environment provide favourable conditions for DNA preservation. This review looks at studies that include the use of aDNA in molecular analysis of micromammal fauna, in order to examine the wide array of questions that can be answered in the study of small mammals using new palaeogenetic techniques. This study highlights the bias in current aDNA studies and assesses the future use of aDNA as a tool for the study of micromammal fauna.
The University, Neoliberalism, and the Humanities: A History
Authors: Shumway David
Published: November 2017

Neoliberalism has since the 1970s had a significant negative impact on higher education in the U.S., but this ideology and political program is not solely to blame for the current situation of the humanities or the university. The American university was never the autonomous institution imagined by German idealists, but it was rather always strongly connected to both the state and civil society. Many of the cultural currents and social forces that have led to the reduction in public spending on higher education and to lower enrollments in the humanities long antedate neoliberalism.
The Genealogy of an Image, or, What Does Literature (Not) Have To Do with the History of Computing? : Tracing the Sources and Reception of Gulliver’s “Knowledge Engine”
Authors: Rodgers Johannah
Published: November 2017

The illustration of the “knowledge engine” included in early editions of Gulliver’s Travels is an engraving of a sketch from the notebook of Lemuel Gulliver. In other words, it is a purely fictional object. Yet, Swift's fictional invention and its graphic representations have become part of the documented historical lineage of computing machines. Furthermore, one of Swift’s purposes for inventing the “knowledge engine” was to satirize the scientific and technical cultures that now claim it as part of their history. As one piece of the elaborate discursive and material code of Gulliver’s Travels, “the knowledge engine,” its sources, and its reception offer some unique insights into the relationships that exist amongst factual and fictional narratives, scientific and humanistic discourse, words and images, and print and digital technologies. Although numerous scientific and philosophical texts have been cited as possible sources informing Swift’s satirical invention, this article considers a lesser known one, John Peter’s 1677 pamphlet Artificial Versifying, or the Schoolboy’s Recreation, which is itself a print-based textual machine for generating lines of Latin hexameter verse.

While total physical activity decreases over the life course, sports and leisure-time physical activity (LTPA) have shown to increase after transition to retirement. This paper aimed to investigate whether this change in sports participation differs (1) between non-migrant persons (NMP) versus persons with a migrant background (PMB), and (2) by acculturation status. Data was drawn from 16 waves of the German Socio-Economic Panel Study (SOEP) including 2664 NMP and 569 PMB. PMB were grouped according to acculturation status (integrated, assimilated, marginalised, separated), assessed regarding three dimensions (language, social interaction and identification). We applied multilevel logistic regression models, adjusting for sex, retirement age, socioeconomic status, health status and body mass index. Our results show that (1) transition to retirement led to an increase in the sports participation of NMP during the first 5 years and the subsequent 5 years after retirement. Changes in sports participation were modified by migration status: In PMB sports participation increased to a lesser extent than in NMP. (2) While sports participation of integrated PMB was not significantly different from NMP in the preretirement phase, sports participation among integrated PMB increased less after retirement compared with NMP. Marginalized and assimilated PMB did not show consistent sports participation patterns before retirement, but seemingly increased their sports participation less than NMP over the retirement transition. Separated PMB had particularly low levels of sports participation. Considering that LTPA is a key factor for healthy ageing, the increasing gap in levels of sports participation after transition to retirement indicates the need for interventions targeting physical activity of the older migrant population.
