Prediction of Crowd Flow in City Complex with Missing Data

Crowd flow forecasting plays an important role in risk assessment and public safety. It is a difficult task due to complex spatial-temporal dependencies as well as missing values in data. A number of models are proposed to predict crowd flow on city-scale, yet the missing pattern in city complex environment is seldomly considered. We propose a crowd flow forecasting model, Imputed Spatial-Temporal Convolution network(ISTC) to accurately predict the crowd flow in large complex buildings. ISTC uses convolution layers, whose structures are configured by graphs, to model the spatial-temporal correlations. Meanwhile ISTC adds imputation layers to handle the missing data. We demonstrate our model on several real data sets collected from sensors in a large six-floor commercial complex building. The results show that ISTC outperforms the baseline methods and is capable of handling data with as much as 40% missing data.
On Euclidean diagrams and geometrical knowledge

We argue against the claim that the employment of diagrams in Euclidean geometry gives rise to gaps in the proofs. First, we argue that it is a mistake to evaluate its merits through the lenses of Hilbert’s formal reconstruction. Second, we elucidate the abilities employed in diagram-based inferences in the Elements and show that diagrams are mathematically reputable tools. Finally, we complement our analysis with a review of recent experimental results purporting to show that, not only is the Euclidean diagram-based practice strictly regimented, it is rooted in cognitive abilities that are universally shared.

Climate-entrepreneurship in response to climate change Lessons from the Korean emissions trading scheme ( ETS )

Purpose – This study aims to explore South Korean firms’ reactions to climate change issues and the Korean emissions trading scheme (ETS) from the perspective of proactive climate-entrepreneurship. Differences in attitude toward the Korean ETS, implementation of carbon management practices and performance regarding operations, market and emission reductions are also investigated. Design/methodology/approach – A research model was developed to investigate the differences in corporate perception of climate change. Using a cluster analysis and analysis of variance with 94 South Korean companies subject to the Korean ETS, the study identified carbon strategies and examined differences in characteristics among the strategies. This study undertook a robustness test by comparing the results from a large sample (n= 261) with those of the original sample (n= 94). Findings – The study identifies four different carbon strategies based on climate-entrepreneurial proactivity: the “explorer,” “hesitator,” “attempter” and “laggard. ” The “explorer” cluster is likely to have a proactive stance toward the Korean ETS regulation, while the “laggard” cluster shows resistance to this new climate policy. Entrepreneurial proactivity in carbon strategies is related to the actual adoption, implementation and effectiveness of carbonmanagement practices. Originality/value – This research is one of the few studies to explore differences in corporate response to climate change from the perspective of entrepreneurship. The study provides a theoretical foundation for extending the literature on the strategic management of climate change issues.
Hybrid Bonds and Audit Fees

This study examines the association between issuing hybrid bonds and audit fees. Using samples for the firms issuing hybrid bonds during the period 2003–2017 in Korean stock market, I find that issuance of hybrid bonds is positively associated with audit fees, audit hours and audit fee per hour. It shows that auditors spend more audit hours and increase the hourly fee rate when their clients issue hybrid bonds. I also find that the audit fees and audit hours tend to increase as the scale of hybrid bonds increases accordingly. This finding supports my hypothesis that when the firms issue hybrid bonds, auditors detect the increased risk the clients might have and they consider more hybrid bonds as a greater potential risk. Thus, auditors tend to increase audit efforts and charge higher audit fee per hour to control audit failure risk and improve audit quality.
Effects of taekwondo kicks on head accelerations and injury potential : a pilot study : original research article

Background : In taekwondo (TKD), the incidence of concussion is four times greater than in American gridiron football. Biomechanical studies of concussion in taekwondo are scarce. Research question : To assess the effect of head impact biomechanics as a result of taekwondo kicks. Type of study : Between-groups design. Methods : Two male (22.0±0.0 years, 184±0.0cm, 81.3±1.8 kg) and two female (0.0±2.8 years, 171.0±1.4 cm, 63.0±5.2 kg) elite taekwondo athletes participated in this study. Head linear acceleration (RLA) and head injury criterion (HIC) data were collected from five different head kicks randomly performed five times. A Hybrid II Crash Dummy head (H2D) was instrumented with a tri-axial accelerometer. Results : Significant differences were found between kicks in RLA (eta2=3.8) and HIC (eta2=4.6) in the men and women (RLA, eta2=4.5 and HIC, eta2=4.7). Post-hoc analyses showed differences in RLA between the jump back kick (61.6±31.0 g) and clench axe kick (33.3±11.1 g) in males (ES=0.9). HIC analysis revealed differences between the jump back kick (556.8±679.2) and jump hook kick (191.0±37.2) (ES=0.7) and in head velocity between the turning kick (5.0±0.5 m.s-1) and jump hook kick (3.2±1.3 m.s-1, ES=1.1) in the males. In the females, there was a difference between the jump back (HIC: 236.8±104.3) and clench axe kicks (22.2±11.2) (ES=1.2) and in foot velocity between the turning (15.7±1.2 m.s-1) and clench axe kicks (9.1±2.3 m.s-1) (ES=1.2). Conclusions : Previous research reported RLA values of 67.0 g (HIC=167) in boxing compared to 72.8 g (HIC=667) in TKD. These high magnitudes of injury-related measures highlight the need for the implementation of more safety precautions.
DESIGN FOR BIOELECTRIC SYSTEM

Plant microbial fuel cell is processed by microbial at plants’ root. In other research Moss and algae was applied on soil and water. Electricity was produced at low level just to supply small FM radio and small LED light. This research aimed to developed more efficient plant microbial fuel cell by choosing more appropriate aquatic plants, size of cells and size of electrodes. Provide circuit system that will enhanced efficiency of electric produced. Design of containers to provide PMFC cell that produce up to 5 volts. Three aquatic plants were applied: Water lettuce, Devil’s Ivy and Lucky Bamboo. Comparison were made between 3 sizes of containers: small 200, medium 400 and large, 600 millilitre and three size of electrodes, small1 x 2.5, medium 2.5 x5 and large 2.5 x7.5 cm. Electricity was observed for 100 days. Result founds that Water lettuce produced maximum electricity at 1039 millivolt per 1 cell, but plants last only 15-30 days while Lucky bamboo produce maximum 978 millivolt with longest life of 90 days. Devil’s Ivy produce maximum at 963 millivolts per 1 cell while plants last 70 days. Size of cell and electrodes found to be most efficient are medium size of 400 millilitres cell and 2.5 X 5 electrodes. The circuit was designed using parallel and series to provide electricity appropriate to low voltage appliances. In order to design the containers, Fusion software was used to minimize materials and the system used vertical arrangement with purpose of filling water from top containers down to lower ones, so it is more practical than horizontal cell where water needs to fill each cell separately from previous research. Six PMFC cells can charge Nickel Metal Hydride battery (NiMH) of 1.2 volt ,950 mAh within 36.18 hours, while 18 PMFC cells can charge 5 volt battery, 11000 mAh within 27 days with energy harvesting circuit.
Reproductive biology of the African moonfish, Selene dorsalis (Gill, 1862) (Carangidae) in continental shelf of Côte d’Ivoire fishery (West Africa)

The present investigation was conducted to study the reproductive biology of the Selene dorsalis (Gill, 1862) in continental shelf of Côte d’Ivoire fishery from March 2016 to February 2017. Sampling was done each month by trawler fishing. A total of 386 (7.5 to 30.3 cm and 7.20 to 496.63 g) were used. The sex ratio was 1: 0.97. All Length-Weight Relationship were statistically highly significant. The coefficient b (3.00, 3.06 and 3.03 respectively for male, female and both sexes) of the Length-Weight Relationship of S. dorsalis showed isometric growth. The condition factor indicated that Females (1.94 ± 0.14%) had higher condition factor than males (1.88 ± 0.14%). GSI ranged from 0.03 % to 5.76%. HIS varied between 0.37 % and 1.97 %. S. dorsalis didn’t use energy stored in liver for development of the ovaries. Size at first maturity of females (21.29 cm) was slightly higher than males (19.09 cm).
APPLICATION OF MULTI-GENERATIONAL MODELS IN LCD TV DIFFUSIONS

This study applies three multi-generational model to expresses the diffusion of multi-generational LCD TVs. Furthermore, this work conducts the analysis of forecast accuracy among the 32-, 40-, 42-, and 46-inch LCD TVs for the multi-generational models. The effect of word of mouth is the greatest for 32-inch LCD TVs because 32-inch LCD TVs enter into the market much earlier than other larger-sized LCD TVs and consumers of 32-inch LCD TVs rely the most on the promotions from previous consumers. For all LCD TV sizes, the forecasting errors are the smallest in predicting cumulative shipments of 46-inch LCD TVs in all multi-generational models. According to the criteria developed by Martin and Witt (1989), the forecasting ability was “good” in predicting cumulative shipments of 46-inch LCD TVs, but only “reasonable” in predicting cumulative shipments of 32-, 40-, and 42-inch LCD TVs for multi-generational Bass and Pearl models. Our proposed multi-generational models predict large-sized 42and 46-inch LCD TVs better than smaller-sized LCD TVs. The size of 32and 40LCD TVs were not large enough and brought to the market earlier than the 42and 46-inch LCD TVs. When the 42and 46-inch LCD TVs entered the market, consumers felt that the 42and 46-inch LCD TVs were much greater than the traditional LCD TVs. Consequently, the demand for large 42and 46-inch LCD TVs grew rapidly. Thus, the multi-generational Pearl models, which considers how the large-sized LCD TVs substitute for small-sized LCD TVs, perform well in predicting large-sized LCD TVs.
Effect of 1-MCP on ethylene regulation and quality of tomato cv . Red Ore

1-MCP is a new tool for regulating ethylene and preserving the quality of fresh produce. Tomato fruit Solanum lycopersicum cv. Red Ore harvested at green and pink stages was used to examine the effect of 1-MCP on their ethylene production and quality. After treating with 1-MCP for 24 hours, ethylene, ACS, ACC, CO2, color, firmness and weight loss were measured. Differences in ethylene production at mature green and pink stages, might be due to the effect of 1-MCP on ethylene production through changed activity of ACS, result in blocking of autocatalysis (mature green) and autoinhibition (pink stage). The shelf lives were improved in 1-MCP-treated fruit at both stages of harvest as indicated by the decrease in respiration, softening, and weight loss, along with the delay in color change (a-value). Our results newly suggest that 1-MCP treatment can have different affects on tomato ethylene production depending on maturation stages (green or pink), but contribute to prolong the shelf life in both stages of tomato fruit.
Marx : An early post-Keynesian ? A comparison of Marx ' s economics with the contributions by Sraffa , Keynes , Kalecki and Minsky

This paper compares Marx’s economics with those by Sraffa, Keynes, Kalecki and Minsky. The paper takes an ‘ex post’ view on the matter and rather looks at the output side of the respective authors, but not at the input side. This means no attempt is made at studying in a systematic way, if and to what extent Sraffa, Keynes, Kalecki and Minsky were individually influenced by Marx’s work. First, the relationship between Marx’s theory of value and Sraffa’s reformulation of the classical theory of prices and distribution is reviewed. Then the relationship between Marx’s and Keynes’s monetary theory is examined relying on an interpretation of Marx’s theory of value as a ‘monetary theory of value’. Next, some light is shed on the Marx-Kalecki connection focusing on Marx’s theory of simple and extended reproduction and the built-in, although not fully elaborated ‘principle of effective demand’ and the related theories of distribution and accumulation. Finally, Marx’s and Minsky’s views on financial instability and crises are scrutinised. It is concluded that Marx should not be considered as an ‘early post-Keynesian’ but rather as an important forerunner of modern post-Keynesianism, with certain similarities, but also some important differences, and several areas of compatibility.
Impact of household cooking on release of fluorinated compounds PFOA and PFOS from Tefal coated cookware to foods

Perfluorinated compounds (PFCs) have taken worldwide attention in recent years. Several PFCs are being used in manufacturing food contact materials, including non-stick coatings (polytetrafluoroethylene (PTFE) or Teflon) for cookware and also their use in paper coatings for oiland moisture-resistant. PFCs are suggested as a new class of Persistent organic pollutant (POP), where they are chemical stability and do not degrade well naturally hence may accumulate in the body and poses problems for human safety. Thus, it is necessary to assess the migration of PFCs from food contact articles to food under typical cooking conditions. The main objective of this investigation was to study the effect of cooking at prolonged use (repeating for ten times) in household Tefal utensils on leaching PFOA and PFOS compounds from the Teflon layer which coats the inner surface of utensils to food-contact such as tomatoes fruit as the acidic food and white dry beans as the non-acidic food without and with adding of table salt. Also, measurement the surface morphology of Tefal layer before and after cooking by using small shapes as a pattern of Tefal cookware which analyzed by X-ray Diffraction (XRD) and X-ray Microanalysis (EDX), as well Environmental Scanning Electron Microscopy (ESEM). The obtained results indicated that, when the repeat of cooking increased from 1 up to 10 times, the amounts of Perfluorinated compounds (PFOS and PFOA, especially PFOS) were progressively increased in the food contact (tomatoes paste or white dry beans) from the Tefal cookware. On the other side, the addition of table salt to the tested samples at all repeats of cooking (1, 5 and 10 times) caused a highly leaching of perfluorinated compounds from the Teflon layer to food-contact more than the same tested samples at the same conditions without salt. Therefore, the acidic food such as tomatoes paste was more effect on the amounts of both PFOS and PFOA in the food-contact than the non-acidic food. Before that, the ESEM images of coating surface of Tefal layer after repeat of cooking exhibited some damage.
Using Markov Chains to Understand the Sequence of Drivers' Gaze Transitions During Lane-Changes in Automated Driving

This paper reports the results of a driving simulator study, which analyzed differences in drivers’ raw gaze transition patterns during different stages of a lane-change maneuver, measured during manual, partially and conditionally automated driving. To understand whether the different levels of automation affected behaviour, and particularly how visual attention was distributed during a lane-change maneuver, a Markov chains approach was used to compare gaze transitions between the different information sources available in the surrounding road and cockpit environment, for each of the three drives. Results showed that drivers initiated fewer safety-related inspections (for example to the wing mirrors) during partial automation, throughout the whole lane change maneuver, possibly because they were focusing on how to the transition of control from automation. Drivers in this condition also had a higher probability of checking the system’s HMI, to verify the automation’s status. In contrast, during conditional automation, the lack of a need for vehicle control by the driver resulted in more gaze transitions between information sources, and fewer gazes to locations where a potential hazard could be present, when compared to manual. Finally, drivers generally only deviated their gaze towards information related to aspects of vehicle control they were responsible for, which we conclude could make them susceptible to missing hazards during both routine and safety-critical take-overs.
Gravity Recovery And Climate Experiment (GRACE) Terrestrial Water Storage (TWS)

10 Africa, a continent endowed with huge water resources that sustain its agricultural activities is 11 increasingly coming under threat from impacts of climate extremes (droughts and floods), which 12 puts the very precious water resource into jeopardy. Understanding the relationship between 13 climate variability and water storage over the continent, therefore, is paramount in order to 14 inform future water management strategies. This study employs Gravity Recovery And Climate 15 Experiment (GRACE) satellite products and the higher order (fourth order cumulant) statistical 16 independent component analysis (ICA) method to study the relationship between Terrestrial 17 Water Storage (TWS) changes and five global climate-teleconnection indices; El Niño-Southern 18 Oscillation (ENSO), North Atlantic Oscillation (NAO), Madden-Julian Oscillation (MJO), 19 Quasi-Biennial Oscillation (QBO) and the Indian Ocean Dipole (IOD) over Africa for the period 20 2003-2014. Pearson correlation analysis is applied to extract the connections between these 21 climate indices (CIs) and TWS, from which some known strong CI-rainfall relationships (e.g., 22 over equatorial eastern Africa) are found. Results indicate unique linear-relationships and 23 regions that exhibit strong linkages between CIs and TWS. Moreover, unique regions having 24 strong CI-TWS connections that are completely different from the typical ENSO-rainfall 25 connections over eastern and southern Africa are also identified. Furthermore, the results indicate 26 that the first dominant Independent Components (IC) of the CIs are linked to NAO, and are 27 characterized by significant reductions of TWS over southern Africa. The second dominant ICs 28 are associated with IOD and are characterized by significant increases in TWS over equatorial 29 eastern Africa, while the combined ENSO and MJO are apparently linked to the third ICs, which 30 are also associated with significant increase in TWS changes over both southern Africa as well 31 as equatorial eastern Africa.
The Prevalence of Thrombocytopenia in Patients with Chronic Hepatitis B and C

E manifestations are commonly observed in patients with chronic hepatitis C. One of these manifestations is thrombocytopenia. Several different mechanisms are reported to be related with this abnormality. These mechanism include: 1) portal hypertension and hypersplenism in end stage liver disease (cirrhosis). 2) autoimmune reaction to platelets. 3) direct infection of platelets and megakaryocytes by HCV. Several reports have shown that HCV infection even in noncirrhotic patients, is one of the causes of thrombocytopenia in different countries. In addition, some reports have shown that thrombocytopenia is associated with chronic hepatitis B. It is estimated that approximately 400,000 people in Iran are chronically infected with HCV and also more than 2,000,000 people are infected with HBV There is no survey study association between thrombocytopenia. The aims of present study were: 1) to assess the prevalence of thrombocytopenia in noncirrhotic patients with chronic hepatitis C and B in Iran. 2) to determine the relationship between the prevalence of thrombocytopenia with HBV infection, HCV infection, age and sex.
The adaptive side of psychopathy: Investigating adaptive characteristics associated with the psychopathic personality

Psychopathy is commonly defined as a disorder characterized by a lack of empathy, impulsivity, and callousness. While generally regarded as maladaptive, past findings support an association between specific adaptive traits, such as fearlessness, and psychopathy. The present dissertation focused on two goals: examining which adaptive traits are associated with psychopathy and developing an instrument to measure those adaptive traits. Our findings suggest that a large array of adaptive traits is associated with the concept of psychopathy. Furthermore, the numerous studies relating to the development and subsequent validation of the Durand Adaptive Psychopathic Traits Questionnaire support its efficacy and incremental validity over existing instruments assessing adaptive psychopathic traits.
Measurement techniques for identifying and quantifying hydroxymethanesulfonate (HMS) in an aqueous matrix and particulate matter using aerosol mass spectrometry and ion chromatography

Abstract. Oxidation of sulfur dioxide (SO2) in the gas phase and in cloud and fog water leads to the formation of sulfate that contributes to ambient particulate matter (PM). For severe haze events with low-light conditions, current models underestimate the levels of sulfate formation that occur exclusively via the oxidation of sulfur dioxide. We show here that measurement techniques commonly used in the field to analyze PM composition can fail to efficiently separate sulfur-containing species, resulting in the possible misidentification of compounds. Hydroxymethanesulfonate (HMS), a sulfur(IV) species that can be present in fog and cloud water, has been largely neglected in both chemical models and field measurements of PM composition. As HMS is formed without oxidation, it represents a pathway for SO2 to contribute to PM under low-light conditions. In this work, we evaluate two techniques for the specific quantification of HMS and sulfate in PM, ion chromatography (IC) and aerosol mass spectrometry (AMS). In cases in which the dominant sulfur-containing species are ammonium sulfate or HMS, differences in AMS fragmentation patterns can be used to identify HMS. However, the AMS quantification of HMS in complex ambient mixtures containing multiple inorganic and organic sulfur species is challenging due to the lack of unique organic fragments and the variability of fractional contributions of HxSOy+ ions as a function of the matrix. We describe an improved IC method that provides efficient separation of sulfate and HMS and thus allows for the identification and quantification of both. The results of this work provide a technical description of the efficiency and limitations of these techniques as well as a method that enables further studies of the contribution of S(IV) versus S(VI) species to PM under low-light atmospheric conditions.
