Statistical Results

Ride-hailing, as a popular shared-transportation method, has been operated in many areas all over the world. Researchers conducted various researches based on global cases. They argued on whether car-hailing is an effective travel mode for emission reduction and drew different conclusions. The detailed emission performance of the ride-hailing system depends on the cases. Therefore, there is an urgent demand to reduce the overall picking up distance during the dispatch. In this study, we try to satisfy this demand by proposing an optimization method combined with a prediction model to minimize the global void cruising distance when solving the dispatch problem. We use Didi ride-hailing data on one day for simulation and found that our method can reduce the picking up distance by 7.51% compared with the baseline greedy algorithm. The proposed algorithm additionally makes the average waiting time of passengers more than 4 minutes shorter. The statistical results also show that the performance of our method is stable. Almost the metric in all cases can be kept in a low interval. What is more, we did a day-to-day comparison. We found that, despite the different spatial-temporal distribution of orders and drivers on different day conditions, there are little differences in the performance of the method. We also provide temporal analysis on the changing pattern of void cruising distance and quantity of orders on weekdays and weekends. Our findings show that our method can averagely reduce more void cruising distance when ride-hailing is active compared with the traditional greedy algorithm. The result also shows that the method can stably reduce void cruising distance by about 4000 to 5000 m per order across one day. We believe that our findings can improve deeper insight into the mechanism of the ride-hailing system and contribute to further studies.

Descriptive Statistical Analysis

This paper is a descriptive statistical analysis of geospatial and temporal distributions of victimized people (killed, injured, affected and damage) with specific reference to geophysical, meteorological, climatological, biological and hydrological disasters that have occurred in the world of from 1900 to 2013 year. In addition, people affected by the various natural disasters could be classified as invisible victims as they are not recognized as victims either by the state or society, and consequently they do not receive adequate protection, assistance and support. Statistical research was conducted on data from the international database of the Centre for Research on Disaster Epidemiology Disaster (CRED) in Brussels. Temporal analysis examined the distribution and effects of natural disasters on people, at intervals of ten years. The same methodology was adopted for analyses of geospatial distribution of victimized people because of natural disasters by continent. The aim of the research is to determine the geospatial and temporal distribution of victimization of people with natural disasters in the world geospace in the period from 1900 to 2013. The survey results clearly indicate an increase in the number and severity of the consequences of natural disasters.

Insight Into

The canine heartworm is a common and serious nematode parasite of domestic dogs in many parts of the world. Although nematode neuroanatomy is fairly well documented, the emphasis has been on sensory anatomy and primarily in free-living soil species and ascarids. Lee and Miller reported on the muscular anatomy in the heartworm, but provided little insight into the peripheral nervous system or myoneural relationships. The classical fine-structural description of nematode muscle innervation is Rosenbluth's earlier work in Ascaris. Since the pharmacological effects of some nematacides currently being developed are neuromuscular in nature, a better understanding of heartworm myoneural anatomy, particularly in reference to the synaptic region is warranted.

Insight Into

This essay examines a polemic between two Baudelaire critics of the 1930s, Jean Cassou and Benjamin Fondane, which centered on the relationship of poetry to progressive politics and metaphysics. I argue that a return to Baudelaire's poetry can yield insight into what seems like an impasse in Cassou and Fondane. Baudelaire provides the possibility of realigning metaphysics and politics so that poetry has the potential to become the space in which we can begin to think the two of them together, as opposed to seeing them in unresolvable tension. Or rather, the tension that Baudelaire animates between the two allows us a new way of thinking about the role of esthetics in moments of political crisis. We can in some ways see Baudelaire as responding, avant la lettre, to two of his early twentieth-century readers who correctly perceived his work as the space that breathes a new urgency into the questions of how modern poetry relates to the world from which it springs and in which it intervenes.

Abstract— The Manabí Hydrographic Demarcation (DHM) is characterized as the only one that does not receive input from Andes Mountains, therefore, its water network is fed exclusively by the rainfall that occurs in the rainy season and that the warm current of El Niño plays a fundamental role in its production. In order to have technical information, important for the planning, control and development of the water resources of the DHM, in this research is made a temporal analysis of the monthly precipitation for 55 years, period 1963-2017. The National Institute of Hydrology and Meteorology of Ecuador (INAMHI) in station M005, located in the Botanical Garden of the Technical University of Manabí (Universidad Técnica de Manabí) in Portoviejo, obtained these records. An analysis is made of the monthly and annual patterns, establishing that the El Niño events that occurred in 1983, 1997 and 1998, have set guidelines for the change in rainwater production at the intensity and temporal distribution levels, increasing the months of drought, while the levels of rainfall increase, concentrating in fewer months, basically in February and March. This is a situation that increases the water deficit especially when there is not enough infrastructure of hydraulic works for the storage and regulation of runoff.   Index Terms— Hydrology, rainfall, monthly distribution, annually distribution, climate change, El Niño phenomenon

Status Of Women

Written almost half a century apart, Rajmohan’s Wife (1864) and The Home and the World (1916) can be read as women centric texts written in colonial India. The plot of both the texts is set in Bengal, the cultural and political centre of colonial India. Rajmohan’s Wife, arguably the first Indian English novel, is one of the first novels to realistically represent ‘Woman’ in the nineteenth century. Set in a newly emerging society of India, it provides an insight into the status of women, their susceptibility and dependence on men. The Home and the World, written at the height of Swadeshi movement in Bengal, presents its woman protagonist in a much progressive space. The paper closely examines these two texts and argues that women enact their agency in relational spaces which leads to the process of their ‘becoming’. The paper analyses this journey of the progress of the self, which starts with Matangini and culminates in Bimala. The paper concludes that women’s journey to emancipation is symbolic of the journey of the nation to independence.

The World Health Organization (WHO) has recently announced the spread of novel coronavirus (nCoV) globally and has declared it a pandemic. The probable source of transmission of the virus, which is from animal to human and human to human contact, has been established. As per the statistics reported by the WHO on 11th April 2020, data has shown that more than sixteen lakh confirmed cases have been identified globally. The reported cases related to nCoV in India have been rising substantially. The review article discusses the characteristics of nCoV in detail with the probability of potentially effective old drugs that may inhibit the virus. The research may further emphasize and draw the attention of the world towards the development of an effective vaccine as well as alternative therapies. Moreover, the article will help to bridge the gap between the new researchers since it’s the current thrust area of research.

AB InBev is today’s uncontested world leader of the beer market. It represents over 20 per cent of global beer sales, with more than 450 million hectolitres a year flowing all around the world. Its Belgian predecessor, Interbrew, was a success story stemming from the 1971 secret merger of the country’s two leading brewers: Artois and Piedboeuf. Based on first-hand material originating from company and private archives as well as interviews with managers and key family actors, this is the first study to explore the history of the company through the nineteenth and twentieth centuries.The story starts in the mid-nineteenth century with the scientific breakthroughs that revolutionized the beer industry and allowed both Artois and Piedboeuf to prosper in a local environment. Instrumental in this respect were the respective families and their successive heirs in stabilizing and developing their firms. Despite the intense difficulties of two world wars in the decades to follow, they emerged stronger than ever and through the 1960s became undisputed leaders in the national market. Then, in an unprecedented move, Artois and Piedboeuf secretly merged their shareholding in 1971, though keeping their operations separate until 1987 when they openly and operationally merged to become Interbrew. Throughout their histories Artois, Piedboeuf, and their successor companies have kept a controlling family ownership. This book provides a unique insight into both the complex history of these three family breweries and their path to becoming a prominent global company, and the growth and consolidation of the beer market through the nineteenth and twentieth centuries.

Psalm 104 is a majestic hymn to creation, a dynamic corollary to the more formal presentation of the creation of the world in Genesis 1. Reflection upon some of the passages provides us with insight into the biblical author’s appreciation for nature, an attitude that needs to inspire us in this age of ecological crisis. Though the biblical text is unaware of such an ecological crisis; nonetheless, passages shine forth that can speak to us in our modern age of global warming and environmental collapse.

Insight Into

Drawing from Van Gennep and Caffee’s conceptualization of liminality, this autoethnographic narrative portrays the author’s rites of passage into academia and through the death of her father. These fundamental developmental transitions and losses emerged concomitantly within the backdrop of a pandemic, further cloaking the world in grief and disequilibrium. Incorporating the voice of the personal as professional, the author portrays her existential struggles in relinquishing her cherished role as a palliative care social worker and living through her dad’s final months during a time of restricted social interaction. Interwoven throughout the narrative appear stories of strife, hope, grief, and professional epiphanies of purpose and insider privilege. The paper embraces both personal and professional conflicts and provides insight into the ways in which the unique setting of a pandemic can provide clarity for navigating the liminal states of separation, transition, and incorporation.
