Electric vehicles don’t eliminate the negative side effects of vehicular travel. They simply move the problems elsewhere – often to contexts where they become more opaque and difficult to address. When we start to exchange one set of side effects for another, the exchange rates become confusing. This opens a space for public relations firms, news pundits, environmentalists, and others to step in and define the terms of exchange to their liking.

Humanity has come a long way, particularly where development is concerned. Unfortunately, we have paid a heavy price for it too. Man has encroached upon nature, and now is reeling under the after-effects of the same. With the effects of pollution and subsequently climate change felt acutely by one and all, the entire world is in a race to discover quick fixes for it. In this attempt, electric vehicles are being hailed as the magical formula that will deliver us from the evils of environmental pollution. It has the 'clean' label attached to it. But are they as 'clean' as is being claimed? This question is especially of vital importance when it comes to a country like India. India has seen a meteoric rise in the last few decades. It's on the fast-track road to development but at the heavy price of forsaking the environment. The necessity to change the development track to take environmental sustainability into account is of utmost importance. So, the question that arises is, are EVs really right for India? Do we really have the infrastructure in place to claim EVs to be the elixir vitae delivering us from the evils of environmental pollution? Will it really be the panacea we are hoping it to be, or are we running after a mirage?

Electric vehicles (EV) are boasted as a key part of the solution to the pressing issue of climate change. Such claims have been upheld by numerous governments which provide financial incentives for EV ownership and invest heavily in infrastructure that would facilitate mass market introduction of EVs. However, the extent of EVs' environmental impact depends on a number of circumstances. This paper aims to assess EVs' contributions towards reduction of carbon dioxide (CO2) emissions, by performing a comprehensive literature review of assessments performed on this topic, and assessing a survey of potential EV consumers' attitudes. Based on a Well-to-Wheel (WTW) assessment, EVs charged by renewables generate emissions in the range of 0.6 g - 11.4 g CO2-eq/km, whereas internal combustion engine vehicles (ICEV) are found to emit 60 to over 200 g CO2-eq/km. EVs charged by coal on the other hand contribute to 120 - 207 g CO2-eq/km, which is more than ICEVs in some categories. C...

This paper concludes that compared to conventional fossil-fuelled vehicle technologies, electric vehicles (EVs) are the best and most robust option with regard to moving to a zero emission road transport system. They enable significant to very deep (98%) 'reductions' in greenhouse gas emissions, where large reductions depend on the extent that the Australian electricity generation will eventually use renewable energy. Fuel cell vehicles appear not to have the same benefits as battery electric vehicles. They perform only slightly better than conventional fossil-fuelled vehicles in terms of energy use per km. In contrast, EVs use approximately a factor of 3-5 times less energy. In fact, fuel cell vehicles are expected to produce a large 'increase' in greenhouse gas emission of about a factor of two, but have the potential to substantially reduce greenhouse gas emission of about 80%, but have the potential to substantially reduce greenhouse gas emissions in the long ter...

Unlike for many consumer products, there has been no strong environmental case for extending the life of internal combustion engine cars as the majority of their environmental impact is fuel consumed in use and not the energy and materials involved in manufacturing. Indeed, with improving fuel efficiency, product life extension is environmentally undesirable; older, less fuel-efficient cars need to be replaced by newer more fuel-efficient models. Electric vehicles (EVs) are predominantly considered environmentally beneficial by using an increasingly decarbonised fuel – electricity. However, LCA analyses show that EVs have substantial environmental impacts in their materials, manufacturing and disposal. The high ‘embedded’ environmental impacts of EVs fundamentally change the case for product life extension. Thus, product life extension is desirable for EVs and they are suited to it. While petrol and diesel cars have an average lifetime mileage of 124,000 miles (200,000 Kilometres), ...

Electric vehicles (EVs) are often thought to be an important means for reducing both the greenhouse gas emissions and energy consumption of global transport, particularly for road passenger transport. They are potentially more fuel efficient than comparable internal combustion engine vehicles (ICEVs), particularly in urban areas, because of regenerative braking. It is well-recognised that the energy efficiency of EVs decreases with the range the batteries must provide (because of rising battery mass), and that greenhouse gas comparisons with ICEVs depend on the grid electricity source. However, this paper argues that comparing EVs and ICEVs is much more complex than generally recognised. Uncertainties occur in both primary energy use and greenhouse gas emission calculations. Further, it may not be legitimate to evaluate these terms on a simple vehicle-km basis, because of spillover effects.

Many governments have supported the introduction of electric vehicles (EVs) through purchase subsidies or waiving fuel taxes. The key findings of this paper are that the benefits of EVs may have been overstated, at least for some countries, as their energy savings and climate mitigation advantages depend on such factors as annual kilometres travelled per vehicle, electricity fuel mix, vehicle size and even local conditions. Because serious climate change has already arrived in the form of increasing frequency and severity of extreme events, we do not have the decades required for electricity production to be predominantly from non-carbon sources. Further, there are a variety of other challenges facing private transport-EVs just as much as conventionally powered vehicles. These include traffic casualties, non-engine air and noise pollution, light pollution, land requirements for roads and parking, and the intrusion of roads into natural habitats. With the promotion of EVs, these other transport problems run the risk of being downplayed. If all the environmental challenges facing road vehicles are to be effectively and quickly tackled, significant reductions in road vehicular travel are needed.
Zaragoza, España, 1960, 32 pp, tamaño de bolsillo: 8'5 x 12'5 cm.
Recuperación digital de una «hora apostólica» redactada por Pedro Casaldáliga, publicada sin nombre de autor por el Consejo Diocesano de Hombres de Acción Católica de la Arquidiócesis de Zaragoza, bajo el nihil obstat del arzobispo Casimiro Morcillo. Guarda la forma acostumbrada por aquellos años de las «horas santas», dedicadas «al Santísimo» habitualmente,, pero transformada por Casaldáliga en una velada comunitaria de espiritualidad y mística apostólica, para encender, convencer, confirmar y «en-thus-iasmar» a los «seguidores de la Causa de Jesús» "avant la lettre". Es del año 1960, antes del Concilio Vaticano II. Significativamente, el formato «de bolsillo» con que fue impresa, habla de la intención de hacerla susceptible de ser llevada consigo, personalmente, en la cartera, en el bolsillo, por los «militantes» apostólicos, que en aquel contexto eclesial fueron sobre todo los miembros de Acción Católica, los entonces llamados movimientos apostólicos, los Cursillos de Cristiandad (en los que Casaldáliga trabajó con especial intensidad, como movimiento apostólico de choque, de abordaje, de «conversión», en España y también, llevándolos a África, a Guinea Ecuatorial). Aun siendo deudora la obra -como no podría ser de otra manera- de los rasgos de la espiritualidad preconciliar, para quienes lo conocemos, se nos transparenta el carisma espiritual y apostólico de Pedro Casaldáliga, ya antes del Concilio y antes de la Espiritualidad de la Liberación, que tanto le harían crecer personal y espiritualmente.
PUBLIC APOLOGY Recently I published a review of Gabe Paquette's European Seaborne Empires. I ended my review with a suggestion of white supremacy. It was as wrong as it was unfair. Paquette, of all people, has made a point of bringing Latin America scholarship (particularly Luso and Spanish American) into the view of Anglophone academia. I have changed the ending of my review in social media and forthcoming print publication to take away all innuendo without giving up what I consider is a fair critique.

The analysis of ethnic-linguistic minorities and their delicate balance with the territory in which they insinuate, within which they debate between integra- tion, preservation of one’s cultural identity and participatory forms of living, it has always been a pause for thought of the geographical disciplines, and more generally of the human sciences. This essay is dedicated to the Grecian area (Calabria) – result of the overlapping of the direct descendants with the first settlers of Magna Graecia, which occurred around the 8th century B.C. on the shores of the Ionian sea (Violi 1997) – whose territory has important criticalities, mostly due to the demographic dynamics underway and due to the continuous decline in the quality of citizenship services (education, health, mobility). How- ever, the area in question presents spaces for experimentation with new forms of transformation, that have to privilege a bottom up governance, and enhance- ment of identity and landscape resources, also from a tourist point of view.

The paper presents the design of speech recognition system that uses preprocessing, feature extraction and classification stages. In preprocessing stage a de-noising is done to get the speech data without noise. In feature extraction stage Linear Predictive Coding (LPC), Mel Frequency Cepstral Coefficients (MFCC), and Spectrogram methods are used to extract the features of the word. Neural Networks (NN) was used to classify the spoken words to different patterns so the system can recognize unknown spoken words according to these patterns. The set of spoken words are used in simulation of the system. The comparative results of the system have been provided using above mentioned feature extraction methods.

This paper introduces a new approach to the study of Paleolithic minds. It is developed on the basis of the phenomenological concept of intentionality: the mind's central characteristic of being about or directed at something. In phenomenology, the world is considered not qua fact, but qua appearance, as a correlate of the mind's intentional activity. Both world-appearance and
