Multivariate Control Chart Based on Kernel PCA for Monitoring Mixed Variable and Attribute Quality Characteristics
Authors: Ahsan Muhammad , Mashuri Muhammad , Wibawati  , Khusna Hidayatul , Lee Muhammad Hisyam
Published: November 2020

The need for a control chart that can visualize and recognize the symmetric or asymmetric pattern of the monitoring process with more than one type of quality characteristic is a necessity in the era of Industry 4.0. In the past, the control charts were only developed to monitor one kind of quality characteristic. Several control charts were created to deal with this problem. However, there are some problems and drawbacks to the conventional mixed charts. In this study, another approach is used to monitor mixed quality characteristics by applying the Kernel Principal Component Analyisis (KPCA) method. Using the Hotelling’s T2 statistic, the kernel PCA mix chart is proposed to simultaneously monitor the variable and attribute quality characteristics. Due to its ability to estimate the asymmetric pattern of the mixed process, the kernel density estimation (KDE) used in the proposed chart has successfully estimated the control limits that produce ARL0 at about 370 for α=0.00273. Through several experiments based on the proportion of the attribute characteristics and kernel functions, the proposed chart demonstrates better performance in detecting outlier and shift in the process. When it is applied to monitor the synthetic data, the proposed chart can detect the shift accurately. Additionally, the proposed chart outperforms the performance of the conventional mixed chart based on PCA mix by producing lower false alarm with more accurate detection of out of control processes.
Existence of Three Solutions for a Nonlinear Discrete Boundary Value Problem with ϕc-Laplacian
Authors: Chen Yanshan , Zhou Zhan
Published: November 2020

In this paper, based on critical point theory, we mainly focus on the multiplicity of nontrivial solutions for a nonlinear discrete Dirichlet boundary value problem involving the mean curvature operator. Without imposing the symmetry or oscillating behavior at infinity on the nonlinear term f, we respectively obtain the sufficient conditions for the existence of at least three non-trivial solutions and the existence of at least two non-trivial solutions under different assumptions on f. In addition, by using the maximum principle, we also deduce the existence of at least three positive solutions from our conclusion. As far as we know, our results are supplements to some well-known ones.

Authors: S. Egoshin N. , A. Konev A. , A. Shelupanov A.
Published: November 2020

This article covers one of the fundamental problems of information security—building a threat model. The article discusses a new method for identifying typical threats to information confidentiality based on the information flow model. The threat model is based on the description of the system. An incorrect description of the system leads to the formation of an incorrect threat model. A review of the subject area revealed several approaches used to describe the system in terms of circulating information flows. Each of these approaches has its own pros and cons. The model of information flows proposed in this work reduces the description of any information system to an eight-digit alphabet. Analysis of the structure of the elementary information flow identified four typical threats to confidentiality, the Cartesian product of a set of threats and a set of streams is a complete model of typical threats to the confidentiality of information processed in cyberspace.
Data Deduplication System Based on Content-Defined Chunking Using Bytes Pair Frequency Occurrence
Authors: Saeed Ahmed Sardar M. , George Loay E.
Published: November 2020

Every second, millions of data are being generated due to the use of emerging technologies. It is very challenging to store and handle such a large amount of data. Data deduplication is a solution for this problem. It is a new technique that eliminates duplicate data and stores only a single copy of data, reducing storage utilization and the cost of maintaining redundant data. Content-defined chunking (CDC) has been playing an important role in data deduplication systems due to its ability to detect high redundancy. In this paper, we focused on deduplication system optimization by tuning relevant factors in CDC to identify chunk cut-points and introduce an efficient fingerprint using a new hash function. We proposed a novel bytes frequency-based chunking (BFBC) algorithm and a new low-cost hashing function. To evaluate the efficiency of the proposed system, extensive experiments were done using two different datasets. In all experiments, the proposed system persistently outperformed the common CDC algorithms, achieving a better storage gain ratio and enhancing both chunking and hashing throughput. Practically, our experiments show that BFBC is 10 times faster than basic sliding window (BSW) and approximately three times faster than two thresholds two divisors (TTTD). The proposed triple hash function algorithm is five times faster than SHA1 and MD5 and achieves a better deduplication elimination ratio (DER) than other CDC algorithms. The symmetry of our work is based on the balance between the proposed system performance parameters and its reflection on the system efficiency compared to other deduplication systems.
A C0-Semigroup of Ulam Unstable Operators
Authors: Acu Ana Maria , Raşa Ioan
Published: November 2020

The Ulam stability of the composition of two Ulam stable operators has been investigated by several authors. Composition of operators is a key concept when speaking about C0-semigroups. Examples of C0-semigroups formed with Ulam stable operators are known. In this paper, we construct a C0-semigroup (Rt)t≥0 on C[0,1] such that for each t>0, Rt is Ulam unstable. Moreover, we compute the central moments of Rt and establish a Voronovskaja-type formula. This enables to prove that C2[0,1] is contained in the domain D(A) of the infinitesimal generator of the semigroup. We raise the problem to fully characterize the domain D(A).
Finite-Field Calculations of Transition Properties by the Fock Space Relativistic Coupled Cluster Method: Transitions between Different Fock Space Sectors
Authors: Zaitsevskii Andréi , Oleynichenko Alexander V. , Eliav Ephraim
Published: November 2020

Reliable information on transition matrix elements of various property operators between molecular electronic states is of crucial importance for predicting spectroscopic, electric, magnetic and radiative properties of molecules. The finite-field technique is a simple and rather accurate tool for evaluating transition matrix elements of first-order properties in the frames of the Fock space relativistic coupled cluster approach. We formulate and discuss the extension of this technique to the case of transitions between the electronic states associated with different sectors of the Fock space. Pilot applications to the evaluation of transition dipole moments between the closed-shell-like states (vacuum sector) and those dominated by single excitations of the Fermi vacuum (the 1h1p sector) in heavy atoms (Xe and Hg) and simple molecules of heavy element compounds (I2 and TlF) are reported.

Published: November 2020

The proliferation of Internet of Things devices and services and their integration in everyday environments led to the emergence of intelligent offices, classrooms, conference, and meeting rooms that adhere to the paradigm of Ambient Intelligence. Usually, the type of activities performed in such environments (i.e., presentations and lectures) can be enhanced by the use of large Interactive Boards that—among others—allow access to digital content, promote collaboration, enhance the process of exchanging ideas, and increase the engagement of the audience. Additionally, the board contents are expected to be plenty, in terms of quantity, and diverse, in terms of type (e.g., textual data, pictorial data, multimedia, figures, and charts), which unavoidably makes their manipulation over a large display tiring and cumbersome, especially when the interaction lasts for a considerable amount of time (e.g., during a class hour). Acknowledging both the shortcomings and potentials of Interactive Boards in intelligent conference rooms, meeting rooms, and classrooms, this work introduces a sophisticated framework named CognitOS Board, which takes advantage of (i) the intelligent facilities offered by the environment and (ii) the amenities offered by wall-to-wall displays, in order to enhance presentation-related activities. In this article, we describe the design process of CognitOS Board, elaborate on the available functionality, and discuss the results of a user-based evaluation study.
Morpho-Functional Alterations in the Gills of a Seawater Teleost, the Ornate Wrasse (Thalassoma pavo L.), after Short-Term Exposure to Chlorpyrifos
Authors: Macirella Rachele , Curcio Vittoria , Brunelli Elvira
Published: November 2020

Chlorpyrifos (CPF) is an organophosphorus insecticide commonly used for domestic and agricultural purposes. The risk posed by environmental contamination from CPF is well acknowledged, and it has been detected worldwide in aquatic habitats and coastal areas. In addition, due to its slower degradation in seawater compared to freshwater, CPF is of particular concern for marine environments. Here, we investigated for the first time the morpho-functional alterations induced by CPF on the gills of Thalassoma pavo, a widespread species in the Mediterranean Sea. We tested the effects of two sublethal concentrations (4 and 8 µg/L) after 48 and 96 h. Our study demonstrates that the alterations induced by CPF are dose and time-dependent and highlight the harmful properties of this insecticide. After exposure to the low tested concentration, the more frequent alteration is an intense proliferation of the primary epithelium, whereas after exposure to the high concentration, the primary epithelium proliferation is less extensive, and the most evident effects are the thinning of secondary lamellae and the ectopia of chloride and goblet cells. CPF also modulated the expression of Na+/K+-ATPase. Dilation of lamellar apical tips, pillar cell degeneration, and appearance of aneurysms are often observed.
Simulations of Phage T7 Capsid Expansion Reveal the Role of Molecular Sterics on Dynamics
Authors: Whitford Paul C. , Jiang Wen , Serwer Philip
Published: November 2020

Molecular dynamics techniques provide numerous strategies for investigating biomolecular energetics, though quantitative analysis is often only accessible for relatively small (frequently monomeric) systems. To address this limit, we use simulations in combination with a simplified energetic model to study complex rearrangements in a large assembly. We use cryo-EM reconstructions to simulate the DNA packaging-associated 3 nm expansion of the protein shell of an initially assembled phage T7 capsid (called procapsid or capsid I). This is accompanied by a disorder–order transition and expansion-associated externalization displacement of the 420 N-terminal tails of the shell proteins. For the simulations, we use an all-atom structure-based model (1.07 million atoms), which is specifically designed to probe the influence of molecular sterics on dynamics. We find that the rate at which the N-terminal tails undergo translocation depends heavily on their position within hexons and pentons. Specifically, trans-shell displacements of the hexon E subunits are the most frequent and hexon A subunits are the least frequent. The simulations also implicate numerous tail translocation intermediates during tail translocation that involve topological traps, as well as sterically induced barriers. The presented study establishes a foundation for understanding the precise relationship between molecular structure and phage maturation.

Published: November 2020

Knowledge of the antibody-mediated immune response to SARS-CoV-2 is crucial to understand virus immunogenicity, establish seroprevalence, and determine whether subjects or recovered patients are at risk for infection/reinfection and would therefore benefit from vaccination. Here, we describe a novel and simple cell-ELISA specifically designed to measure viral spike S1-specific IgG produced in vitro by B cells in peripheral blood mononuclear cell (PBMC) cultures from a cohort of 45 asymptomatic (n = 24) and symptomatic (n = 21) individuals, with age ranging from 8 to 99 years. All subjects underwent ELISA serological screening twice, at the same time as the cell-ELISA (T2) as well as 35–60 days earlier (T1). Cryopreserved PBMCs of healthy donors obtained years before the COVID-19 pandemic were also included in the analysis. The preliminary results presented here show that out of 45 tested subjects, 16 individuals (35.5%) were positive to the cell-ELISA, 11 (24.5%) were concomitantly positive in the serological screening (T1 and/or T2), and only one person was exclusively positive in ELISA (T1) and negative in cell-ELISA, though values were close to the cutoff. Of note, five individuals (11.2%) tested negative in ELISA but positive in cell-ELISA and thus, they appear to have circulating B cells that produce antibodies against SARS-CoV-2, likely at levels that are undetectable in the serum, which challenges the negative results of the serological screening. The relative level of in vitro secreted IgG was measurable in positive subjects, ranging from 7 to 50 ng/well. Accordingly, all anti-SARS-CoV-2 antibody-positive subjects previously reported moderate to severe symptoms attributable to COVID-19, even though the RT-PCR data were rarely available to confirm viral infection. Overall, the described cell-ELISA might be an effective method for detecting subjects who encountered the virus in the past, and thus helpful to improve serological ELISA tests in the case of undetectable/equivocal circulating IgG levels, and a suitable and improved tool to better evaluate SARS-CoV-2-specific humoral immunity in the COVID-19 pandemic.

Published: November 2020

(1) Background: The influenza virus continues to cause significant annual morbidity and mortality. The overall efficacy of seasonal influenza vaccination is suboptimal, which is partly due to host immune factors. The effects of imprinting and repeated seasonal influenza vaccination were investigated to assess for immune factors and mechanisms that impact influenza vaccine responses. (2) Methods: Twenty participants were enrolled into a prospective pilot study based on birth cohort and seasonal influenza immunization history. Immunologic parameters were assessed over a six-month period after the seasonal influenza vaccine was administered. (3) Results: There was no significant imprinting effect, as measured by hemagglutination inhibition (HAI) fold change, HAI geometric mean titer (GMT) for Day 29 or Day 180 post-vaccination and antigen- specific antibody-secreting cells (ASC) for Day 8 post-vaccination. Individuals who had minimal prior seasonal influenza vaccination had a higher magnitude ASC response and a higher HAI fold change post-vaccination than individuals who were repeatedly vaccinated. (4) Conclusions: Repeated seasonal influenza vaccination resulted in a decreased fold change of the immune response, although individuals in this cohort tended to have high HAI titers at baseline that persisted after vaccination. Imprinting effects were not observed in this cohort. These host immune factors should be considered in the development of universal influenza vaccines. ClinicalTrials.gov Identifier: NCT03686514.

Summary: аssessment of the prevalence of type 2 diabetes mellitus (DM2) in the adult population of Tskhinval, Republic of South Ossetia. Material and methods. The outpatient records of 811 patients registered with the endocrinologist of the municipal polyclinic with a diagnosis of DM2 were analyzed. The study took into account outpatient records of 478 women and 333 men. To obtain a representative sample, patients (aged 38 to 93 years) were stratified by age, gender, and body mass index. The level of glycemia and the year of occurrence in the initial setting of DM2 were also taken into account. Results. The average age at the diagnosis of DM2 in women was higher than in men (62 and 57 years, respectively). The prevalence of DM2 in relation to gender was higher in women than in men (59 and 41%). At the age of 51–58 years, the largest number of newly detected cases of DM2 was observed. Conclusions. The prevalence of DM2 among the population of Tskhinval is 4.4%. Given the data from the NATION study that only 54% of cases of DM2 are diagnosed, the number of patients with DM2 in Tskhinval may be about 2.5 thousand people (about 8.1% of the urban population). The obtained data should form the basis of the service for medical examination of the population, prevention and treatment of DM2 in the Republic of South Ossetia

Authors: Elistratova Y. , Seminenko A. , Minko V.
Published: November 2020

The article analyzes various theoretical approaches to describing the processes of formation of scale layers on the working surfaces of heat exchangers. The main tasks include analyzing existing models of contamination of heat exchange channels, determining the main mechanism of salt deposition on the heating surface of plate heat exchangers of heat supply systems, determining the main factors that determine the intensity of salt deposition on the working plate in accordance with the dynamics of heat and hydraulic processes in heat exchange channels formed by corrugated plates, as well as forming trends for further research. The article presents the main results of research devoted to the study of contamination processes on heating surfaces. Inaccuracies in the proposed approaches to describing the nature of the formation of salt deposition layers are identified. By generalizing existing approaches to the mathematical description of pollution processes, the main assumptions are revealed when describing the processes of salt deposition on working plates. A hypothesis is proposed about the influence of the location of channels relative to the inlet pipe on the uniformity of the flow distribution between parallel channels in the device. There is a fairly large gap between the existing computational methods for modeling pollution processes and the actual distribution of scale layers during the operation of heat exchange equipment of heat supply systems

Published: November 2020

The leveraging of digital technologies at the intersection of architecture and urbanism allows for imagining scenarios for the future of cities. In line with recent cross-disciplinary research, this paper aims at investigating how large-scale prototyping applied to urban space can generate impact and provide a working model for Resilient Strategies. DATAField, a placemaking intervention developed in New Orleans, investigates how the synthetic integration of ‘the making’ of place, the importance of citizens’ engagement and the incorporation of digital technologies can provide an operative framework for large scale urban prototyping. Introducing models for urban hydrology management, citizen-engaged science, visualization strategies of underlying infrastructural systems and resultant urban prototyping related to resiliency, DATAField demonstrates how digital technologies implemented through systemic approaches can be a powerful tool to design in soft-land and to strengthen citizens’ awareness of ‘how we can live with water’ in vulnerable ecosystems.

Published: November 2020

For a more accurate study of the kinetics of the barley seeds drying, a convective drying stand with a computerized system of data acquisition and processing on the change in the mass and temperature of the sample from the drying time was used.
The kinetic curves of the drying process under the action of three factors were constructed: the temperature of the coolant, heating medium movement rate and the initial moisture content of the seeds. Studies were also conducted and the germination of barley seeds under the action of these factors was analysed.
Studies have shown that all factors affect the kinetics of the drying process, but the greatest influence on the germination of seed material comes from the influence of the temperature of the coolant. A three-factor effect on the germination of barley seeds on the 7th day of germination is presented, that indicates the need for low-temperature drying at a coolant temperature of 50°C.
In order to increase the intensification and energy efficiency of the drying process, the proposed two-stage drying mode is 65/50°C, which provides intensive heating and evaporation of moisture from the material at the initial stage of the process. Studies on the germination of barley seeds in a two-stage mode showed that the specified drying mode provides a high germination rate of the material up to 99%, an intensity of 83% and an energy efficiency of 62% compared to a rational single-stage drying mode of 50°C and can be recommended for drying barley seeds.

Published: November 2020

This paper presents a theoretical investigation of quantum beats of excitons in GaAs/AlGaAs circular cylindrical quantum wires. A three-level model of excitons, including a ground state and two excited states, has been applied to derive the renormalized wavefunctions and the time-dependent absorption intensity of excitons when the system is irradiated by a strong pump laser resonating with the distance between the two excited-levels. Our results show that a periodic oscillation form of the absorption intensity, obvious evidence of the quantum beat behavior, has appeared. Furthermore, the mechanism of the generation, as well as the effects of the wire radius and the pump laser detuning on the frequency (period) and amplitude of quantum beats, have been explained in detail. These results suggest potential applications in the fabrication of some quantum computation devices.

Published: November 2020

Tube shape-controlled Ce-doped Y3Al5O12 (tube-Ce:YAG) single-crystal scintillators were directly grown from a melt via the micro-pulling-down method using a specially-designed iridium crucible. Back-scattering Laue images and X-ray diffraction measurements revealed the tube-Ce:YAG was a single crystal with the YAG phase. Ce distribution in the tangential direction of the tube-Ce:YAG specimen showed that Ce concentrations around the capillary positions were lower than at the corners. This was caused by the small Ce segregation coefficient in the YAG single crystal and from the small convection in the meniscus. The scintillation properties of tube-Ce:YAG specimens were comparable with previously reported Ce:YAG single crystals.
Powered Knee and Ankle Prosthesis with Adaptive Control Enables Climbing Stairs with Different Stair Heights, Cadences, and Gait Patterns
Authors: Hood Sarah , Gabert Lukas , Lenzi Tommaso
Published: November 2020

Powered prostheses can enable individuals with above-knee amputations to ascend stairs step-over-step. To accomplish this task, available stair ascent controllers impose a pre-defined joint impedance behavior or follow a pre-programmed position trajectory. These control approaches have proved successful in the laboratory. However, they are not robust to changes in stair height or cadence, which is essential for real-world ambulation. Here we present an adaptive stair ascent controller that enables individuals with above-knee amputations to climb stairs of varying stair heights at their preferred cadence and with their preferred gait pattern. We found that modulating the prosthesis knee and ankle position as a function of the user’s thigh in swing provides toe clearance for varying stair heights. In stance, modulating the torque-angle relationship as a function of the prosthesis knee position at foot contact provides sufficient torque assistance for climbing stairs of different heights. Furthermore, the proposed controller enables individuals to climb stairs at their preferred cadence and gait pattern, such as step-by-step, step-over-step, and two-step, similar to able-bodied individuals. We anticipate the proposed control strategy will improve the robustness of powered prostheses to environmental and human variance without the need for expert tuning, machine learning, or direct subject intervention, which may enable powered prostheses to more easily move from the lab to the real-world.

Both infrastructure and research, make communications and exchanges between distant places possible. As a consequence, geographic positions and administrative borders are less and less significant compared to the polarity of the individual cities. From the port and infrastructural systems’ point of view, Trieste, can closely resemble this model by strengthening the two drivers for development, quality of life and employment opportunity. The specificity that needs to be investigated is the complex system that joins port logistics with innovation promoted by AREA Science Park among others.
New Features of the rivershore: climate change and new relations between town and water
Authors: Casu Alessandra , Zaccagna Jlenia
Published: November 2020

Climate scenarios show that Mediterranean areas will be affected by torrential patterns of rain, that can cause difficulties in urban life in coastal areas, mainly due to the draining systems and to the sea-level. Lisbon is on the estuary of Tagus river, which would be probably affected by run-off and by the forecasted rising sea-level. Redesigning its relationship with water, trying to make this urban area more resilient, becomes crucial and asks to study run-off and sea-level rise for 2100 and for intermediate steps, to adapt the urban life and its spaces to the occurring scenarios.

In Italy, the transformative predictions of the municipal urban planning instruments are very often far away from the socio-economic dynamics. In fact, the political component considers the oversizing of urban transformative projections as a solution to improve the situation of the territories in crisis for several aspects. This work analyses the projections of the urban planning instruments in force in the coastal municipalities of Emilia-Romagna. The work aims to highlight how the planned urban areas can change the future settlement structure in the case study area.

In the present study, the Marine Floristic Ecological Index (MARFEI) was tested to assess the impacts by using marine benthic macrophytes and pressures by using the Macroalgae-Land Uses Simplified Index (MA-LUSI) in the Marmara Sea (Turkey). Sampling of benthic macrophytes was made from 0-5 m depth at 29 different sites during the summer periods of 2017, 2018 and 2019. The study revealed good ecological status class (ESC) for 6 sites, moderate for 11 sites, poor for 8 sites and bad for 4 sites. MARFEIeqr showed a negative linear relationship with the pressure index MA-LUSI.

The “FLEX 2018” cruise, organized by the CNR-ISMAR in frame of the ESA “FLEXSense Campaign 2018” and CMEMS project, provided a ground station for several bio-optical instruments that investigated the coastal waters of the Tyrrhenian Sea in June 2018. The field measurements were performed in time synergy with Sentinel 3A and Sentinel 3B satellites and HyPlant airborne imaging spectrometer. Active and passive fluorescence were investigated at different scales in coastal waters to support preparatory activities of the FLuorescence EXplorer (FLEX) satellite mission.
Fritjof Capra Tentang Melek Ekologi Menuju Masyarakat Berkelanjutan
Authors: Keraf A. Sonny
Published: November 2020

Abstract: The global environmental crisis and resulting disasters today have threatened life in general, especially human life. According to Fritjof Capra, one feasible solution to this global environmental crisis is to build sustainable human communities based on what he calls ecological literacy. Ecological literacy itself stands for our ability to understand the principles of organization common to all living systems and is used as a guideline for creating sustainable human communities. Capra underlines the need to redesign our communities, including our educational communities, business communities, political communities and all aspects of our daily life, so that the principles of ecology become principles of all our human communities. For Capra, the implementation of such a sustainable society is possible to achieve through the so-called eco-design, which is both scientifically and technically feasible. Nonetheless, the success of the major project to develop a sustainable eco-literate society does not simply depend on the individual awareness of eco-literacy. It also depends on the political will of the government to issue public policies—including legislation—to force all stakeholders to act in accordance with, and based on, ecoliteracy.

 

Keywords: Ecological literacy, ecological principles, sustainable human community, eco-design, sautopoesis dissipative systems, natural capital.

 

Abstrak: Krisis dan bencana lingkungan hidup global telah mengancam kehidupan pada umumnya, termasuk kehidupan manusia. Menurut Fritjof Capra, salah satu solusi untuk mengatasi krisis dan bencana lingkungan hidup global itu adalah dengan membangun masyarakat manusia yang berkelanjutan berdasarkan apa yang disebutnya sebagai melek ekologi, yaitu kemampuan kita untuk memahami prinsip-prinsip pengorganisasi yang berlaku pada semua sistem kehidupan dan menggunakannya sebagai pedoman dalam menciptakan masyarakat yang berkelanjutan. Capra sangat menekankan perlunya merancang ulang komunitas-komunitas kita, termasuk komunitas pendidikan, komunitas bisnis, komunitas politik, dan seluruh kehidupan kita sehari-hari, agar prinsip-prinsip ekologis tersebut diwujudkan sebagai prinsip dari komunitas-komunitas tersebut. Bagi Capra, implementasi dari masyarakat berkelanjutan seperti itu dapat dicapai melalui apa yang disebutnya sebagai rancang bangun ekologis (eco-design) yang secara ilmiah dan teknis sangat layak diterapkan. Hanya saja, keberhasilan proyek besar membangun masyarakat berkelanjutan berdasarkan melek ekologi ini tidak hanya bergantung pada kesadaran moral individu akan melek ekologi di atas. Keberhasilan proyek besar itu juga sangat bergantung pada kemauan politik pemerintah untuk mengeluarkan kebijakan publik—termasuk undang-undang—guna memaksa semua pemangku kepentingan untuk bertindak sesuai dengan dan berdasarkan kesadaran ekologis tadi.

Kata-kata Kunci: Melek ekologi, prinsip-prinsip ekologi , masyarakat berkelanjutan, rancang bangun ekologis, sistem autopoesis disipatif, modal alam.
In Search Of A Christian Public Theology In The Indonesian Context Today
Authors: Adiprasetya Joas
Published: November 2020

Abstract: This article deals with the contemporary task of Christian public theology in constructing a contextual model that is able to maintain the dialectic of commonality and particularity. Such a model must pay attention to the search for common ground among many cultural-religious identities, while at the same time it must respect those identities in their own paticularities. The sensitivity to and solidarity with the victims of the New Order’s’ regime must also be fundamental elements of such a model. To do so, this article discusses two competing theories in social philosophy (liberalism and communitarianism), and their parallel theories in theology (revisionism and post-liberalism). The necessity to construct a more balanced third way between those theories is needed, if Indonesian Christians want to be open to their social and political call and faithful to their Christian distinctiveness.

 

Keywords: Public theology, liberalism, communitarianism, revisionism, post-liberalism, commonality, particularity.

Abstrak: Artikel ini membahas tugas kontemporer teologi publik Kristen dalam mengkonstruksi sebuah model kontekstual yang mampu mempertahankan dialektika kesamaan dan kekhususan. Model semacam ini haruslah memperhatikan usaha menemukan dasar bersama di antara banyak identitas kultural-religius, sekaligus pada saat bersamaan menghargai identitas-identitas tersebut di dalam keunikan mereka masing-masing. Kepekaan dan solidaritas pada para korban di bawah rejim Order Baru di masa silam harus menjadi unsur-unsur mendasar bagi model semacam itu. Artikel ini mendiskusikan dua teori yang saling bersaing di dalam filsafat sosial (liberalisme dan komunitarianisme), dan teori-teori sejajar di dalam teologi (revisionisme dan pascaliberalisme). Tuntutan untuk mengkonstruksi sebuah jalan ketiga yang lebih seimbang antara teori-teori tersebut sungguh dibutuhkan, jika orang-orang Kristen Indonesia ingin berbuka pada panggilan sosial dan politis mereka sembari tetap setia pada keunikan Kristiani mereka.

Kata-kata Kunci: Teologi publik, liberalisme, komunitarianisme, revisionisme, pascaliberalisme, komunalitas, partikularitas.

Dimensi sosial manusia telah lama menjadi subjek telaah filsafat sebagai wujud kesadaran bahwa manusia adalah zoon politikon (Aristoteles) atau homo sociale (Seneca). Pertanyaan umum yang biasa diajukan adalah, apakah manusia memang mampu bertindak secara altruistik, atau apakah manusia memiliki empati alamiah. Analisis ini tentu saja tidak dimonopoli oleh filsafat saja. Belakangan ini, ilmu-ilmu alam dan sosial seperti ekonomi, sosiobiologi, dan neurosains juga terlibat dalam studi atas dimensi yang dipandang khas pada manusia ini. Dalam ranah yang disebut sebagai “ekonomi eksperimental,”’ misalnya, dipelajari perilaku kerjasama antarindividu yang hasilnya diharapkan dapat menjelaskan dasar perilaku sosial manusia.

 

Dalam buku yang terdiri atas empat bab besar ini dianalisis berbagai pandangan mengenai relasi sosial manusia dalam konteks antropologi interdisipliner. Pengarang memperlihatkan perbedaan pandangan mengenai sosialitas dalam setiap bidang ilmu. Dalam disiplin neuroekonomi, sosialitas dipahami sebagai struktur preferensi perilaku manusia yang berakar pada neurobiologi. Dalam fenomenologi sosial dan etika, istilah ini mengacu pada struktur dasar perbedaan dan relasionalitas dalam relasi antarmanusia. Teologi sendiri melihat sosialitas sebagai struktur relasi manusia dengan Tuhan dan sesama. Pengarang buku ini menunjukkan bahwa konsep mengenai aspek sosial manusia dalam bidang-bidang ini memang tidak sama, dan karena itu, pemahaman mengenai sosialitas manusia perlu dibangun berdasarkan konteks disiplin yang bersangkutan.

 

..........................

 

Pembahasan atas topik sosialitas dalam buku ini memang sangat luas dan kaya karena melibatkan banyak pemikir dalam bidang ini seperti Hannah Arendt, Thomas Hobbes, Ernesto Laclau, Chantal Mouffe, Axel Honneth, Charles Taylor, Paul Ricoeur, dan Emmanuel Levinas. Dalam pemaparan mengenai relasi antarmanusia dari sudut teologis, pemikiran filsuf-teolog Søren Kierkegaard banyak sekali digunakan. Di satu sisi, kehadiran begitu banyak pemikir dalam buku ini dapat membuat pembaca kewalahan dalam memahami isinya. Di sisi lain, hal ini justru dapat dilihat sebagai salah satu kekayaan buku ini, yang dapat membuka wawasan pembaca dan mengajaknya untuk lebih mendalami pemikiran tokoh tertentu sesuai dengan minatnya. Seluruh studi ini membawa pengarang kepada kesimpulan bahwa hakikat sosialitas manusia tidak- lah dapat dipahami hanya dengan membandingkannya dengan sosialitas hewan, sebagaimana biasanya dilakukan. Pada akhirnya, hakikat ke- manusiaan, termasuk sosialitasnya, akan tersingkap dalam relasi dan interaksi konkret antarmanusia, entah bersifat positif atau negatif. Hanya dengan demikian kita akan memahami siapakah diri kita yang sesungguh- nya sebagai manusia. (Thomas Hidya Tjaya, Program Studi Ilmu Filsafat, Sekolah Tinggi Filsafat Driyarkara, Jakarta).
