Towards Practical Robot Manipulation using Relational Reinforcement Learning

Learning robotic manipulation tasks using reinforcement learning with sparse rewards is currently impractical due to the outrageous data requirements. Many practical tasks require manipulation of multiple objects and the complexity of such tasks increases with the number of objects. Learning from a curriculum of increasingly complex tasks appears to be a natural solution, but unfortunately, only provides a small performance gain. We hypothesize that the inability of the stateof-the-art algorithms to learn from a curriculum stems from the absence of inductive biases for transferring knowledge from simpler to complex tasks. We show that graph-based relational architectures overcome this limitation and enable learning of complex tasks when provided with a simple curriculum of tasks with increasing numbers of objects. We demonstrate the utility of our framework on a simulated block-stacking task. Starting from scratch, our agent learns to stack six blocks into a tower. Despite using sparse rewards, our method is orders of magnitude more data-efficient and superior in performance to the existing state-of-the-art methods relying on either human demonstrations or task-specific engineering. Furthermore, the learned policy exhibits zero-shot generalization, successfully stacking blocks into taller towers and into previously unseen configurations such as pyramids, without any further training.

SWEARING IN BANJARNESE: A GENDER ANALYSIS

This study aims to analyze the swearing words used by Banjarese. The researchers apply the gender analysis as the main theoretical framework. The data of this study are swearing words commonly used by Banjarese, regardless of age or educational background. The swearing words are classified into; those mostly used by male and those used by female. The researchers draw conclusion after classifying the group of words and what they represent. Based on the findings, it is found that male and female mostly use different words to swear. Female uses wider range of words to swear in comparison to the words used by male.
Vascular Macrophages in Atherosclerosis

Atherosclerosis is the main pathological basis for the occurrence of most cardiovascular diseases, the leading global health threat, and a great burden for society. It has been well established that atherosclerosis is not only a metabolic disorder but also a chronic, sterile, and maladaptive inflammatory process encompassing both innate and adaptive immunity. Macrophages, the major immune cell population in atherosclerotic lesions, have been shown to play critical roles in all stages of atherosclerosis, including the initiation and progression of advanced atherosclerosis. Macrophages have emerged as a novel potential target for antiatherosclerosis therapy. In addition, the macrophage phenotype is greatly influenced by microenvironmental stimuli in the plaques and presents complex heterogeneity. This article reviews the functions of macrophages in different stages of atherosclerosis, as well as the phenotypes and functions of macrophage subsets. New treatment strategies based on macrophage-related inflammation are also discussed.
A Mathematical Framework for IMU Error Propagation with Applications to Preintegration

To fuse information from inertial measurement units (IMU) with other sensors one needs an accurate model for IMU error propagation in terms of position, velocity and orientation, a triplet we call extended pose. In this paper we leverage a nontrivial result, namely log-linearity of inertial navigation equations based on the recently introduced Lie group SE2(3), to transpose the recent methodology of Barfoot and Furgale for associating uncertainty with poses (position, orientation) of SE(3) when using noisy wheel speeds, to the case of extended poses (position, velocity, orientation) of SE2(3) when using noisy IMUs. Besides, our approach to extended poses combined with log-linearity property allows revisiting the theory of preintegration on manifolds and reaching a further theoretic level in this field. We show exact preintegration formulas that account for rotating Earth, that is, centrifugal force and Coriolis effect, may be derived as a byproduct.
Individual Crafting, Collaborative Crafting, and Job Satisfaction: The Mediator Role of Engagement

espanolLa mayor parte de las teorias de job crafting han estudiado el termino como una actividad individual. Pocas investigaciones se han centrado en el crafting colaborativo. El presente estudio tiene dos objetivos. Se pretende adaptar y validar la version espanola de la escala de crafting individual y colaborativo. Ademas, se pretende poner a prueba un modelo de mediacion simple del engagement sobre la relacion entre el crafting individual y colaborativo y la satisfaccion laboral. La muestra esta formada por 301 personas. El analisis de datos se llevo a cabo con el programa Smart PLS v. 3.2. 6. usando minimos cuadrados parciales (PLS). Los resultados muestran que la escala de crafting individual y colaborativo en castellano es valida y fiable. Ademas, existe una mediacion completa del engagement en la relacion job crafting-satisfaccion. El modelo hipotetizado explica un 78.4% de la varianza de la satisfaccion laboral. EnglishMost theories of job crafting understand the term to refer to an individual activity, and only a few studies have focused on collaborative job crafting. The present study has two aims. First, to adapt and validate a Spanish version of the Individual and Collaborative Crafting Scale. Second, to test a simple mediation model of engagement on the relationship between individual and collaborative crafting and job satisfaction. The sample consisted of 301 people. The data were analyzed using the Smart PLS statistical program, version 3.2. 6. , using the partial least squares (PLS) path modeling method. The results reveal that the Spanish language version of the Individual and Collaborative Crafting Scale is both valid and reliable. Moreover, engagement was found to fully mediate the relationship between job crafting and job satisfaction, with the hypothesized model explaining 78.4% of the variance observed in job satisfaction.
Climatic clustering analysis for novel atlas mapping and bioclimatic design recommendations

Defining and determining climatic zones accurately is crucial to inform the decision making of building designers and planners during early design phases of urban development. Characterizing the climatic zones allows estimation of energy requirements in buildings and develop climate adapted energy polices. Climatic zones can be defined by using the statistical cluster analysis. Data from weather stations can be used after standardization with zero mean and unit variance, to confirm that all variables are weighted equally in the cluster analysis. In this paper, a novel atlas for 19 climatic zones is presented that represent a variety of bioclimatic design strategies and recommendations, for passive design, based on a clustering analysis in Iran. The clustering analysis is based on the statistical analysis of daily temperature and relative humidity from 1995 to 2014. The results visualize 19 different climate zones for Iran and indicate the dominance of passive design strategies. As a result, Iran was divided into eight climatic clusters. The results showed that each of the studied clusters require specific strategies in providing indoor comfort. The outputs of this study shed the light on the importance of up-to-date climate characterization and the effectiveness of climate mapping and recommendations to inform decision makers.
Solution Focused Brief Counseling (SFBC): Study in Students with Academic Procrastination

This research was motivated by preliminary research findings which show the level of academic procrastination among the students of Islamic Religious Education Department (PAI) of the Faculty of Tarbiyah and Teacher Training (FTIK) of the State Institute of Islamic Studies (IAIN) Pontianak at 71.88% which is in the high category, even at 8.75% which is in the very high class and the findings of several studies which stated that SFBC effectively overcomes various psychological problems . The research aims to prove the effectiveness of the Treatment Model of Academic Procrastination based on FSBC to reduce the behavior of academic procrastination among students who are writing their undergraduate thesis. In practice, this research used the Research and Development (R&D) approach and the model effectiveness testing, which was is conducted with One Group Pretest-Posttest Experimental Design. The data were collected using a questionnaire and analyzed using percentages and t-test. The results showed that the outcomes of the pretest-posttest average score decreased by 36.533 (from 231.666 to 195.133). Furthermore, the SFBC Model t-test showed a significance value of 0.00 (less than the alpha value of 0.05). Thus, the SFBC is sufficient to reduce the behavior of academic procrastination among the students of the Department of Islamic Religious Education (PAI) of the State Institute of Islamic Studies (IAIN) Pontianak.
Effect of Different Clarification Methods on Volatile Aroma Compound Composition of Virgin Olive Oil

SUMMARY This study investigates the effect of industrial scale filtration of fresh monovarietal virgin olive oil from Buža and Istarska bjelica cultivars on their volatiles, total phenols and sensory characteristics, and compares the oil samples clarified by filtration with those clarified by natural sedimentation/decantation after six months of storage. Filtration had a different effect on volatiles from the oil samples obtained from different cultivars. In the oil from Buža cultivar immediately after filtration only the amount of (Z)-2-pentenol slightly increased, but in Istarska bjelica the oil filtration affected eight compounds (the amount of hexanal, (E)-2-pentenal, (Z)-3-hexenal, (Z)-2-pentenol and (Z)-3-hexen-1-ol increased, while of hexyl acetate, (E)-2-penten-1-ol and (E)-2-hexen-1-ol decreased). In fresh filtered oil from Buža cultivar a slight decrease of total phenols was observed, while in those from Istarska bjelica the decrease was sharp, causing a decrease in the pungency and bitterness. Sedimentation/decantation had advantages over oil filtration of both cultivars, due to improved effect on the preservation of the sensory profile and the level of total phenols. Tentative aroma profiles based on odorant series obtained from the odour activity values were compared to the actual olive oil sensory profiles. These results could have a high level of applications in the olive oil industry for the optimization of the technology for obtaining monovarietal virgin olive oil with preserved specific and typical sensory characteristics, but also may serve experts to choose an appropriate virgin olive oil clarification method prior to analysis of volatile compounds.
The influence of photoperiods on behaviour of quail under different housing systems

This experiment was conducted to investigate the effect of different day times on some maintenance behaviour of Japanese quail (Coturnix Coturnix Japonica). The experiment was carried out at faculty of Veterinary Medicine poultry farm, Zagazig University, Egypt. 120 quail of one day old chick were divided randomly into two equal group (60 birds of each) one group were housed at floor system and the other at cage system. From the obtained results the diurnal variation had a significant effect on feeding behaviour. The ingestive behaviour was increased with floor managed quail at early morning. There was a non-significant difference in walking time between different day times. The wall pecking time wasn't affected with the diurnal hours. We concluded that there was a positive correlation coefficient between the ingestive behaviour of quail and the different diurnal hours as it increase with early morning at floor housed quail. The crouching time was increased with mid-day at battery managed quail.
Weisheng-Tang Ameliorates Acute Ischemic Brain Damage in Mice by Maintaining Blood-Brain Barrier Integrity

Stroke is one of the major causes of death and long-term disability worldwide; the associated breakdown of the blood-brain barrier (BBB) aggravates ischemic brain damage. Accordingly, many medicinal herbs and formulas have been used to treat stroke-related symptoms. In this study, we selected two Korean herbal medicine formulas, Weisheng-tang and Tongxuewan, through Dongeuibogam text-mining analysis, and evaluated their protective effect on BBB disruption and brain damage in stroke. Ischemic brain damage was induced in mice by photothrombotic cortical ischemia. The infarct volume, brain edema, neurological deficits, and motor function 24 h after ischemic injury were analyzed. We investigated BBB breakdown by measuring Evans blue extravasation in addition to endothelial cells, tight junction proteins, protease-activated receptor-1 (PAR-1), and matrix metalloproteinase-9 (MMP-9) using immunofluorescence staining and confocal microscopy. Pretreatment with Weisheng-tang significantly reduced infarct volume and edema and improved neurological and motor functions; however, Tongxuewan did not. In addition, Weisheng-tang decreased brain infarction and edema and recovered neurological and motor deficit in a dose-dependent manner (30, 100, and 300 mg/kg). Weisheng-tang pretreatment resulted in significantly less BBB damage and higher brain microvasculature after focal cerebral ischemia. Tight junction proteins, such as zonula occludens-1 (ZO-1) and claudin-5, were preserved in Weisheng-tang-pretreated mice. Moreover, the ischemic brain in these mice showed suppressed PAR-1 and MMP-9 expression. In conclusion, our findings show that Weisheng-tang, which was selected through literature analysis but has not previously been used as a stroke remedy, exerts protective effects against ischemic brain damage and suggest its possible application for potential stroke patients, especially in the elderly.
Characterization of Smallholder Beef Cattle Production System in Central Vietnam –Revealing Performance, Trends, Constraints, and Future Development

The objective of this study is to evaluate the characteristics of smallholder beef cattle production in Central Vietnam. A total of 360 households were interviewed by using semi-structured questionnaire; a total of 606 beef cows were investigated for evaluating calving interval (CI). Thirty-two fattening cattle were monitored for the estimation of diet structure. Results showed that the cattle herd size was 4.32-4.45 cattle/household. In North Central (NC), 55% of surveyed farmers kept local cattle, 45% kept crossbreeds, and none of surveyed farmers keeping exotic breeds. In South Central (SC), 63% of surveyed farmers kept cross cattle, 32% kept local cattle, and 5% kept exotic breeds. In the breeding method, 70% of surveyed farmers used artificial insemination (AI), 20% used natural mating (NM), and only 10% used both AI and NM in SC, whereas in NC 40% of farmers used AI, 40% used NM, and 20% used both AI and NM. The variety of feedstuffs fed to cattle including roughages and concentrate. The concentrate in the diet for fattening cattle was 25%-35% and protein level was 11%-13%, and the average daily gain of cattle was 0.51-0.63 kg/day. The CI of cows was 12-13 months in SC, whereas in NC it was 13-14 months. There were numerous constraints to cattle production in surveyed households including diseases, lack of good quality feed sources, breeds, knowledge, and lack of capital. In conclusion, cattle production in Central Vietnam is small scale and still largely extensive. There are constraints that must be solved to improve livestock systems in the near future, especially when shifting towards semi-intensive and/or intensive cattle production systems.
Seasonal Changes in Reproductive Hormones of Female Formosan Black Bears (Ursus thibetanus formosanus) in Captivity 圈養雌性台灣黑熊繁殖內分泌 季節性變化之初探

Seasonal changes in serum reproductive hormones of three female Formosan black bears (Ursus thibetanus formosanus) in captivity were studied monthly from April 2001 to May 2003 at the Low Altitude Experimental Station of Endemic Species Research Institute. The LH concentration was significantly higher (ANOVA, p < 0.05) in spring than those in other three seasons, but no significant seasonal differences (p > 0.05) were found for the concentrations of FSH, prolactin, estradiol and progesterone. Also, there were significantly positive correlations in concentrations between FSH and progesterone, between LH and estradiol, between LH and progesterone, and between estradiol and progesterone. The female Formosan black bears seem to be capable for breeding all the year round, but spring is the major mating season. The results of this study provide important reproductive information useful for the preservation of the Formosan black bear.
Do Financial Misconduct Experiences Spur White-Collar Crime?

We use individual police records on criminal activity to investigate whether personal experiences with financial misconduct spur white-collar crime. Experiences with financial misconduct derives from individuals holding accounts at distressed banks where executives are prosecuted for misconduct. We show that individuals with such experiences are two to three times more likely to be convicted of white-collar crime themselves, compared to similar customers of distressed banks where the financial supervisory authority did not press charges. Our results are driven by the extensive margin: the increase in white-collar crime is caused almost exclusively by customers who had no prior history of criminal activity.

Optimization of Phenolic Compound Extraction from Chinese Moringa oleifera Leaves and Antioxidant Activities

Rich in phenolic compounds, Moringa oleifera leaf extract (ME) exhibits significant antioxidant activity both in vitro and in vivo. ME has already been widely used in fields of medicine, functional food, and cosmetics. Ultrasonic extraction (UE) method has been improved to be one of the most effective ways to extract phenols from M. oleifera leaves. The purpose of this study was to optimize ultrasonic extraction of phenols by response surface methodology (RSM). Four parameters were discussed, such as ethanol concentration, solvent-sample ratio, extraction temperature, and extraction time. Also, purification methods of the crude ME by organic solvent extraction and column chromatography were examined. Antioxidant activities of ME and each fraction were evaluated by DPPH, ABTS, and hydroxy radical-scavenging activities and reducing power. The phenol content of the purified ME reached up to 962.6 mg RE/g, extremely higher than the crude extract 107.22 ± 1.93 mg RE/g. The antioxidant activity of the purified ME was also significantly improved. Furthermore, phenols were identified by using the HPLC-MS method, and the results showed that there were 6 phenolic acids and derivatives and 7 flavonoids in ME. Quercetin-3-O-β-D-glucoside isolated from ME showed excellent DPPH and ABTS radical-scavenging abilities, which were comparable to VC.
Clan Masdar in Local Political Contestation (Social-Political Capital Role in Political Marketing)

Local elite competition occurs in many regions in Indonesia. One of them was in West Sulawesi, which was issued by three clans, the Manggranian Clan, the Mengga Clan, and the Masdar Clan. At present, the competition between the Mengga Clan and the Masdar Clan continues. Several political contestations in West Sulawesi have followed by-elections, both governor and regent elections. In the 2012 gubernatorial election, the Masdar Clan was defeated by Aladin S. Mengga (the Mengga Clan) and in the 2017 gubernatorial election, the Masdar Clan could win his victory. This article discusses the role of the Masdar clan socio-political capital in political marketing strategies using qualitative research methods, this study shows the socio-political capital used by the Masdar Clan is related effectively in political marketing activities. Social capital consists of bureaucracy, public trust and characterization carried out in activities through marketing. Political capital in the form of political party support/coalition, representative pairs, political experience, and successful team support is carried out in push marketing and pull marketing activities. Overall, socio-political capital is capital that is superior to the Masdar Clan. However, if examined closely, then social capital "figure" is the most decisive, the capital can make another capital.
Health Workers’ Perspectives on the Outcomes, Enablers, and Barriers to the Implementation of HIV “Test and Treat” Guidelines in Abuja, Nigeria

We evaluated health workers’ perspectives on the implementation of the 2016 HIV “Test and Treat” guidelines in Nigeria. Using semi-structured interviews, qualitative data was collected from twenty health workers meeting inclusion criteria in six study sites. Data exploration was conducted using thematic content analysis. Participants perceived that the “Test and Treat” guidelines improved care for PLHIV, though they also perceived possible congested clinics. Perceived key factors enabling guidelines use were perceived patient benefits, availability of policy document and trainings. Perceived key barriers to guidelines use were poverty among patients, inadequate human resources and stock-outs of HIV testing kits. Further improvements in uptake of guidelines could be achieved by effecting an efficient supply chain system for HIV testing kits, and improved guidelines distribution and capacity building prior to implementation. Additionally, implementing differentiated approaches that decongest clinics, and programs that economically empower patients, could improve guidelines use, as Nigeria scales “Test and Treat” nationwide.
Impact of some intravenously administered drugs (paracetamol, hydrocortisone, dexamethasone and amikacin) on coagulation hemostasis (in vitro evaluation study)

Background:Normally, the coagulation homeostasis prevents bleeding and retain the blood in the vascular system during periods of injury. Unfortunately, pathological factors, drugs or toxins could affect one or more stages of homeostasis mechanisms leading to bleeding or abnormal thrombi. Evaluation of prothrombin time is a favorable test for the screening of extrinsic coagulation mechanism whilst activated partial thromboplastin time measurement is a global coagulation screening method for intrinsic factor.Material and Methods:Blood samples were withdrawn from healthy adults volunteers for clotting times measurements from collected plasma. The effect of paracetamol, hydrocortisone, dexamethasone, and amikacin at different concentrations on coagulation homeostasis was in vitro investigated and compared to control and positive control.Results:High concentrations of all tested drugs except amikacin prolong significantly activated partial thromboplastin time, whilst the effect on the prothrombin time was conflicting.Conclusions:Paracetamol, hydrocortisone, dexamethasone, and amikacin could prolong clotting time expressed in prolongation of activated partial thromboplastin time comparable to the anticoagulants drugs.
