PANDANGAN SONOUCK HURGRONJE TENTANG ISLAM DAN IMPLIKASINYA TERHADAP PRAKTIK HUKUM DAN POLITIK DI INDONESIA
Authors: Ernas Saidin

ABSTRAC

Snouck Hurgronje is a very controversial figure in the history of colonialism in Indonesia. As a prominent colonial scientist and advisor, he has succeeded in building the foundations of thought which were then adopted by the Dutch colonial government as the Inlands Policy which strictly separates the three main problems in the religious life of Muslims in Indonesia; ritual matters, muamalah and politics. This paper shows that the separation between religious rituals and other important aspects such as muamalah and politics has an impact on the deformalization of Islamic law in Indonesia which has placed Islamic law as an inferior legal institution. Whereas the depoliticization of Islamic politics, has weakened the ideology of Islamic politics, some of whose impacts are still felt until today.

ABSTRAK

Snouck Hurgronje adalah sosok yang sangat kontroversial dalam sejarah kolonialisme di Indonesia. Sebagai seorang ilmuwan dan penasehat kolonial yang terkemuka, Ia telah berhasil membangun dasar-dasar pemikiran yang kemudian diadopsi pemerintah kolianl Belanda sebagai Inlands Policy yang memisahkan secara ketat tiga masalah utama dalam kehidupan kegamaan umat Islam di Indonesia; masalah ritual, muamalah dan politik. Tulisan ini menunjukkan bahwa pemisahan antara ritual keagamaan dan aspek-aspek penting lainnya seperti muamalah dan politik telah berdampak terhadap deformalisasi hukum Islam di Indonesia yang telah menempatkan hukum Islam sebagai pranata hukum yang inferior. Sedangkan depolitisasi politik Islam, telah melemahkan ideologi politik Islam yang sebagian dampaknya masih terasa hingga kini.

The Steller’s eiderPolysticta stelleriis a sea duck that breeds in Arctic tundra regions of Russia and Alaska (USA). The Alaska-breeding population is listed as ‘threatened’ under the US Endangered Species Act because of a perceived contraction of the breeding range in North America. Understanding demography of the listed population is critical for evaluating measures that can lead to increased abundance and thus, long-term viability. Specifically, estimates of return rates to breeding areas by adult females and natal areas by juvenile females are needed for planning effective recovery actions. We used a suite of polymorphic loci to genotype individuals and generated genetic profiles of nesting females and female offspring from nest materials collected between 1995 and 2016 in a ~170 km2study area near Utqiagvik, Alaska. We analyzed capture histories of genetically identified individuals to estimate breeding site fidelity, temporary emigration, and philopatry. From a sample of 365 nests, we found that breeding site fidelity of adult females was high (0.91 ± 0.07 SE), and temporary emigration was also high (0.77 ± 0.06) and annually variable (range 0.34-0.97). From egg shell remains of 124 hatched females, we observed 9 recaptures as nesting adults, suggesting that philopatry was also high (range 0.6-1.0). Given the relatively high rates of adult female breeding site fidelity and female philopatry that we estimated, management actions that reduce mortality of adult females and increase annual productivity are likely to help maintain the population of a few hundred breeding Steller’s eiders on the Arctic Coastal Plain of Alaska.

Published: January 2020

The aim of present research is to analyse the verbal memory of teenagers on the basis of their sentence repetition task. We try to answer the question whether the age and the school type how can characterize their sentence repetition.

Our hypothesis was, that the age and the school type can influance on their sentence repetition but the  influance of the school type is stronger than the age factor. We also thought that the structure of the sentences and the number of the syllables of the words whic construct the sentences can influance the punctuality of their sentence repetition results.

In order to discuss the hypothesis the series of experiment was carried out with the participation of teenagers (16 and 18 years, from the secondary grammar and secondary technical school). The test material consisted of 20 sentences, the students task was to repeat them after they had heard them. The analysis was in terms of punctuality, and we also analysed the length and the grammatical structure of the sentences in tems of the punctuality, furthermore the unfilled pauses occurring during the repetiton task and the time of the pauses, even the the types of errors in the incorrect sentences. The statistical anlysis was also done.

The results showed that the elder students reached better achievement especielly those who are studying in the grammar school The repetition of shorter sentences was also better. The analysis of mistakes showed different results in terms of the school type and proved the memory capacity problems of the students studying in different school type.
Infinite Process of Forward and Backward Bifurcations in the Logistic Equation with Two Delays
Authors: Kashchenko Ilia , Kaschenko Sergey
Published: January 2020

Logistic equation with delay play important role in modelling of various biological processes. In this paper we study the behaviour of solutions of a logistic equation with two delays in a small neighbourhood of equilibrium. The main assumption is that Malthusian coefficient is large, so problem is singular perturbed. To study the local dynamics near points of bifurcation an analogues of normal form was constructed. Its coefficients depends on special bounded discontinues function, which takes all its values infinite number of times when large parameter increases to infinity. It is shown that the system under study has such dynamic effect as infinite process of direct and inverse bifurcations as the small parameter tends to zero.
Implementation of the national health policy in PRC (1981–2017)
Authors: Kunpeng Huang
Published: January 2020

Since the founding of the People’s Republic of China, China’s national health and sanitation industry has achieved remarkable achievements. Before the liberation, the Chinese people suffered from hunger, famine and infectious diseases. The average life expectancy was only 35 years old. In the early days of the founding of New China, under the condition that the national strength was extremely weak and there was a serious shortage of medical treatment and medicine, the state adopted a «prevention-based» medical and health strategy to mobilize social resources and effectively curb prevention measures such as changing people’s bad habits and vaccination. The serious threat to the spread of human’s infectious diseases in China has greatly improved the people’s health. Since the reform and opening up, with the rapid development of the economy, people’s material living standards have become increasingly rich, but new challenges have been generated in the health field. Faced with new challenges in the health field, the Chinese medical community conducted a comprehensive analysis and discussion. Based on the summary of relevant experiences of the World Health Organization (WHO), combined with China’s national conditions, it put forward countermeasures for the health of the whole people and provided suggestions for deepening the reform of China’s medical and health system.

Published: January 2020

Prediction of energy use behaviors is a necessary prerequisite for designing personalized and scalable energy efficiency programs. The energy use behaviors of office occupants are different from those of residential occupants and have not yet been studied as intensively as residential occupants. This paper proposes a method based on Markov chain Monte Carlo (MCMC) to predict the energy use behaviors of office occupants. Firstly, an indoor electrical Internet of Things system (IEIoTS) for the office scenario is developed to collect the switching state time series data of selected user electrical equipment (desktop computer, water dispenser, light) and the historical environment parameters. Then, the Metropolis–Hastings (MH) algorithm is used to sample and obtain the optimal solution of the parameters for the office occupants’ behavior function, the model of which includes the energy action model, energy working hours model, and air-conditioner energy use behavior model. Finally, comparative experiments are carried out to evaluate the performance of the proposed method. The experimental results show that while the mean value performs similarly in estimating the energy use model, the proposed method outperforms the Maximum Likelihood Estimation (MLE) method on uncertainty quantification with relatively narrower confidence intervals.

Published: January 2020

This study aimed at exploring the frequency of use and perceived benefits of application of organic matter to the soil in a group of Italian farmers, investigating also the preferred sources of information, to identify potential interventions to promote the improvement of the soil organic matter. The study has been carried out administering a 21-item paper-and-pencil questionnaire to 44 farmers. The results of the study highlighted that the main perceived benefit linked to soil organic matter application is related to its capacity of increasing productivity, while the aspects related to work pace, production costs, and implications with the climate change appeared to be less relevant. According to the results of the study, web targeted information campaigns for the smaller farms operators and training activities for the bigger farms operators are the most effective solutions to make farmers aware of the importance of increasing soil organic matter content.

Published: January 2020

The application of bioorganic fertilizer affects rhizosphere microbes and further improves soil fertility in farmlands. However, the effects of different fertilizers on rhizosphere bacterial community diversity and structure of winter wheat remains unclear. In this study, we explored the effects of different fertilization treatments (no fertilizer added, CK; nitrogen fertilizer, NF; bioorganic fertilizer, BOF) on the rhizosphere bacterial community of winter wheat in the North China Plain. Rhizosphere soil treated with BOF had a higher Shannon index than that of CK and NF. The relative abundance of the Proteobacteria treated with BOF was significantly higher than that of NF, while the Acidobacteria and Planctomycetes were significantly lower. The redundancy analysis (RDA) and Mantel test showed that soil bacterial communities were significantly correlated with pH, nitrate, available phosphorus (AP), and available potassium (AK). Our findings indicated that BOF increased bacterial diversity and the relative abundance of copiotrophic bacteria in rhizosphere soil, while NF reduced bacterial diversity and increased the relative abundance of oligotrophic bacteria. The increase in copiotrophic bacteria in the rhizosphere of winter wheat could indicate an increase in soil nutrient availability, which might have positive implications for soil fertility and crop production.
Is Phytomelatonin a New Plant Hormone?
Authors: Arnao Marino , Hernández-Ruiz Josefa
Published: January 2020

Melatonin (N-acetyl-5-methoxytryptamine) is of particular importance as a chronobiological hormone in mammals, acting as a signal of darkness that provides information to the brain and peripheral organs. It is an endogenous synchronizer for both endocrine (i.e., via neurotransmitter release) and other physiological rhythms. In this work we will try to add to the series of scientific events and discoveries made in plants that, surprisingly, confirm the great similarity of action of melatonin in animals and plants. The most relevant milestones on the 25 years of phytomelatonin studies are presented, from its discovery in 1995 to the discovery of its receptor in plants in 2018, suggesting it should be regarded as a new plant hormone.
Response of Barley Genotypes to Weed Interference in Australia

Published: January 2020

Weed-competitive genotypes could be an important tool in integrated weed management (IWM) practices. However, weed competitiveness is often not considered a priority for breeding high-yielding cultivars. Weed-competitive ability is often evaluated based on weed-suppressive ability (WSA) and weed-tolerance ability (WTA) parameters; however, there is little information on these aspects for barley genotypes in Australia. In this study, the effects of weed interference on eight barley genotypes were assessed. Two years of field experiments were performed in a split-plot design with three replications. Yield loss due to weed interference ranged from 43% to 78%. The weed yield amongst genotypes varied from 0.5 to 1.7 Mg ha−1. Relative yield loss due to weed interference was negatively correlated with WTA and WSA. A negative correlation was also found between WSA and weed seed production (r = −0.72). Similarly, a negative correlation was found between WTA and barley yield in the weedy environment (r = −0.91). The results suggest that a high tillering ability and plant height are desirable attributes for weed competitiveness in the barley genotypes. These results also demonstrated that among the eight barley genotypes, Commander exhibited superior WSA and WTA parameters and therefore, could be used in both low- and high-production systems for weed management. Westminster had a superior WSA parameter. Therefore, it could be used for weed management in organic production systems. These results also implied that genotypic ranking on the basis of WSA and WTA could be used as an important tool in strengthening IWM programs for barley.

Authors: Ye Xiaoxin , Zhang Meng , Zhang Manyun , Ma Yongqing
Published: January 2020

Sunflower broomrape (Orobanche cumana Wallr.) is a weedy root parasite that causes huge damage to sunflower (Helianthus annuus L.). Trap crop can stimulate parasitic seed germination without attachment in trap crop, and it was considered as economic methods for controlling the parasite. In this study, co-culture and pot experiments were conducted to assess the allelopathic activity of maize (Zea mays L.) to stimulate broomrape seeds germination and to evaluate the performance of maize rotation for reducing sunflower broomrape infection. All the tested maize cultivars could induce sunflower broomrape germination, and the most active maize cultivar was N314, which induced approximately 40% broomrape seeds germination. Rotation of maize significantly reduced broomrape infection on subsequent sunflower and increased sunflower biomass. After cultivated N314 for 3 years, broomrape attachment on sunflower was the lowest (0.8 attachment plant−1), and the dry mass of sunflower shoot (28.7 g plant−1) was approximately twice higher than the sunflower without previous crop. The effectiveness of broomrape management was significantly different among various maize cultivars. Meanwhile, the differences among cultivars were decreased with the years of maize cultivated prolonged. Our results confirmed that maize was significantly effective in reducing the sunflower damage caused by sunflower broomrape and suggested that maize rotation could be included in the integrated management of sunflower broomrape.
Polyphenols from Food and Natural Products: Neuroprotection and Safety
Authors: Silva Rui F. M. , Pogačnik Lea
Published: January 2020

Polyphenols are naturally occurring micronutrients that are present in many food sources. Besides being potent antioxidants, these molecules may also possess anti-inflammatory properties. Many studies have highlighted their potential role in the prevention and treatment of various pathological conditions connected to oxidative stress and inflammation (e.g., cancer, and cardiovascular and neurodegenerative disorders). Neurodegenerative diseases are globally one of the main causes of death and represent an enormous burden in terms of human suffering, social distress, and economic costs. Recent data expanded on the initial antioxidant-based mechanism of polyphenols’ action by showing that they are also able to modulate several cell-signaling pathways and mediators. The proposed benefits of polyphenols, either as protective/prophylactic substances or as therapeutic molecules, may be achieved by the consumption of a natural polyphenol-enriched diet, by their use as food supplements, or with formulations as pharmaceutical drugs/nutraceuticals. It has also been proved that the health effects of polyphenols depend on the consumed amount and their bioavailability. However, their overconsumption may raise safety concerns due to the accumulation of high levels of these molecules in the organism, particularly if we consider the loose regulatory legislation regarding the commercialization and use of food supplements. This review addresses the main beneficial effects of food polyphenols, and focuses on neuroprotection and the safety issues related to overconsumption.

Rosmarinus officinalis L. is a traditional herb with various therapeutic applications such as antibacterial, antioxidant, anti-inflammatory, antidepressant, and anticholinesterase activities, and can be used for the prevention or treatment of dementia. In the present study, we tested whether Rosmarinus officinalis L. could counteract scopolamine-induced anxiety, dementia, and brain oxidative stress in the zebrafish model and tried to find the underlying mechanism. Rosmarinus officinalis L. essential oil (REO: 25, 150, and 300 µL/L) was administered by immersion to zebrafish (Danio rerio) once daily for eight days while scopolamine (100 µM) treatment was delivered 30 min before behavioral tests. The antidepressant and cognitive-enhancing actions of the essential oil in the scopolamine zebrafish model was measured in the novel tank diving test (NTT) and Y-maze test. The chemical composition was identified by Gas chromatograph–Mass spectrometry (GC-MS) analysis. The brain oxidative status and acetylcholinesterase (AChE) activity was also determined. REO reversed scopolamine-induced anxiety, memory impairment, and brain oxidative stress. In addition, a reduced brain AChE activity following the administration of REO in scopolamine-treated fish was observed. In conclusion, REO exerted antidepressant-like effect and cognitive-enhancing action and was able to abolish AChE alteration and brain oxidative stress induced by scopolamine.
Numerical Simulation of an InP Photonic Integrated Cross-Connect for Deep Neural Networks on Chip
Authors: Shi Bin , Calabretta Nicola , Stabile Ripalta
Published: January 2020

We propose a novel photonic accelerator architecture based on a broadcast-and-weight approach for a deep neural network through a photonic integrated cross-connect. The single neuron and the complete neural network operation are numerically simulated. The weight calibration and weighted addition are reproduced and demonstrated to behave as in the experimental measurements. A dynamic range higher than 25 dB is predicted, in line with the measurements. The weighted addition operation is also simulated and analyzed as a function of the optical crosstalk and the number of input colors involved. In particular, while an increase in optical crosstalk negatively influences the simulated error, a greater number of channels results in better performance. The iris flower classification problem is solved by implementing the weight matrix of a trained three-layer deep neural network. The performance of the corresponding photonic implementation is numerically investigated by tuning the optical crosstalk and waveguide loss, in order to anticipate energy consumption per operation. The analysis of the prediction error as a function of the optical crosstalk per layer suggests that the first layer is essential to the final accuracy. The ultimate accuracy shows a quasi-linear dependence between the prediction accuracy and the errors per layer for a normalized root mean square error lower than 0.09, suggesting that there is a maximum level of error permitted at the first layer for guaranteeing a final accuracy higher than 89%. However, it is still possible to find good local minima even for an error higher than 0.09, due to the stochastic nature of the network we are analyzing. Lower levels of path losses allow for half the power consumption at the matrix multiplication unit, for the same error level, offering opportunities for further improved performance. The good agreement between the simulations and the experiments offers a solid base for studying the scalability of this kind of network.

Published: January 2020

In this paper we discuss the effects of deslagging practices and the size of electric arc furnace (EAF) slags on structural, microstructural, composition and leaching tests. The samples were collected from seven steelmakers located in Brescia (Lombardy Region, Italy). Nine granularity fractions of four samples were tested to evaluate the influence of the granularity on the leaching tests. The results showed that, in general, the release of the elements arises when the size of the particle decreases, except in one sample, in which vanadium and zinc displayed the opposite trend. X-ray diffraction results suggest that behavior may be ascribed to the effect of the grinding, which causes a different percentage of the phases in the various fractions. In conclusion, the possible effects of the size should also be carefully considered when defining new leaching test requirements for EAF slags.

Published: January 2020

In this paper, we present a novel optical microfluidic cytometry scheme for label-free detection of cells that is based on the self-mixing interferometry (SMI) technique. This device enables simple, fast and accurate detection of the individual cell characteristics and efficient cell type classification. We also propose a novel parameter to classify the cell or particle size. Artificial polystyrene beads and human living cells were measured using this system, and the SMI signal properties were statistically evaluated. The capability of the proposed cytometer for cell type discrimination and size classification has been validated by the measurement results. Our study can provide a very simple technique for cell enumeration and classification without any extra devices such as high-speed camera, photomultiplier and spectrometer. Moreover, the fluorescence staining operation which is necessary in traditional flow cytometry methods is not required either in our system.
