CubeSats have become an interesting innovation in the space sector. Such platforms are being used for several space applications, such as education, Earth remote sensing, science, and defense. As of May 31st, 2018, 855 CubeSats had been launched. Remote sensing application is the main sector in which CubeSats are being used, corresponding to about 45% of all applications. This fact indicates the commercial potential of such a platform. Fifty eight countries have already been involved with developing CubeSats. The most used CubeSat configuration is 3U (about 64%), followed by 1U (18%), while 6U platforms account for about 4%. In this paper, we present an analysis of the current situation regarding CubeSats worldwide, through the use of a dataset built to encompass information about these satellites. The overall success rate of the CubeSat missions is increasing over time. Moreover, considering CubeSat missions as a Bernoulli experiment, and excluding launch failures, the current succ...

The University of Colorado Smead Department of Aerospace Engineering has over a decade of success in designing, building, and operating student led CubeSat missions. The experience and lessons learned from building and operating the CSSWE, MinXSS-1, MinXSS-2, and QB50-Challenger missions have helped grow a knowledge base on the most effective and efficient ways to manage some of the “tall poles” when it comes to student run CubeSat missions. Among these “tall poles” we have seen student turnover, software, and documentation become some of the hardest to knockdown and we present our strategies for doing so. We use the MAXWELL mission (expected to launch in 2021) as a road-map to detail the methodology we have built over the last decade to ensure the greatest chance of mission success. INTRODUCTION CubeSats at the University of Colorado The University of Colorado Smead Aerospace graduate program has launched and operated four successful missions to date: CSSWE [1] [2], MinXSS-1 [3], M...

The Central American Association of Aeronautics and Space (ACAE) and the Costa Rican Institute of Technology (TEC), in partnership with industry and government, have identified the promotion of aerospace as a very promising strategy for economic, scientific, and technological development in Costa Rica. Several studies, including a state-ofthe-art mapping of aerospace industry made by ACAE, the Central American Institute of Business Administration (INCAE) and the Costa Rican Foreign Trade Agency (PROCOMER) [1], have identified actions to enable the development of the aerospace sector in the country. Among them, a significant catalyst would be a practical demonstration of the technical capabilities to develop a space engineering project. The Irazú project is an innovative mission taking place in Costa Rica, which aims to launch the first Central American satellite in orbit by 2018. The project, led by ACAE and TEC, has two main objectives: a) to complete a space project life-cycle, an...

Free and open source hardware repositories provide massive public good, but funding their operation has proven tenuous with conventional business models. This study evaluates business models to foster that public good. Business models for online design repositories are reviewed and a new model is conceptualized to fund repository operations. The greatest added value an open hardware repository brings to the user-developer community is validation and vetting of the designs. A business model was proposed that uses revenue from the vetting process to fund validation studies and sustainable operations of the open hardware repository itself. As the return on investment of laterally-scaled open hardware that can leverage distributed manufacturing has the potential for creating enormous value, maintaining repositories for this hardware enables vast wealth generation for everyone. This is the first study specifically focused on ways to ensure economic sustainability of open hardware repositories.

In this article I analyse the use of the augment in the Apologoi (Books 9 to 12 of the Odyssey). I first explain why I have chosen this work and these books. Second, I describe my methodology in analysing and determining my corpus. As the transmission of the Homeric poems has been problematic, I decided to work only with the forms that are secured by the metre and I therefore describe which morphological rules, metrical laws and bridges render the augment in a form secure (or not). Based on that corpus, I proceed to the actual analysis. In analysing the data I compare the previous (morphological, syntactic and semantic) observations on the augment to the data of the Apologoi. My findings show that the explanation of the augment as a foregrounding device is largely confirmed, but that there are nevertheless exceptions.

Tratto da Un’Ambigua Utopia (a c. di) quarant’anni con Philip K. Dick "Il fantasma della verità" AGENZIA X Mi sono avvicinato tardivamente ai libri di Philip Dick, solo dopo essere stato attirato come una falena dalla luce di Blade Runner. Per Antonio Caronia la pellicola di Ridley Scott: “è un tradimento fondamentale, un film poco dickiano, da un certo punto di vista perché sottolinea temi che in Dick non ci sono e preoccupazioni che lui non ha mai avuto” e ha senz’altro ragione, anche se continuo a pensare che il film brilli di luce propria. Ho letto Ubik prima delle altre opere maggiori di Dick, compreso Gli androidi sognano pecore elettriche?, e il fascino che ha esercitato su di me ha lasciato il segno. Forse una ragione è svelata proprio da Caronia quando afferma che “Dick era un postmoderno, uno che ci dice che il mondo non è unico, che ci sono vari mondi e che si può passare da un universo parallelo all’altro, da un mondo possibile all’altro” e io, da buon boomer, benché recalcitrante e insubordinato, appartengo biograficamente alla postmodernità.

This paper explores the stories of women migrants from Latin America who found themselves living precarious lives and struggling to sustain former idealised notions of their racial and class identities in London. Dispossessed of previous class membership due to an onward feminised precarity, a diminished social capital, undocumented legal statuses, and menial stigmatised jobs, women clung to an idealised perception of social status (shaped by white Eurocentric aspirations) to negotiate and reconfigure class and racial anxieties in London. They engage in various strategies that include processes of whitening through marriage and children, performances of taste and beauty, and negotiating their racialisation at work. These cases reflect the relevance of the coloniality of power, its influence in the subsistence of racial and class ideologies in Latin America, and in a global economy of care that produces and reproduces postcolonial forms of intersectional racialised and gendered exploitation.
This paper aims at investigating the possible links between some dua-listic tendencies in the Hebrew Bible and the socio-religious situation of Persian Yehud. Although it now seems that the province of Yehud was considered by the Achaemenids as little more than a political and cultural « third world », it seems difficult to deny that some trends at least inside the Jewish intelligentsia must have been influenced (if not overtly seduced) by the official version of Zoroastrianism promoted by the Persian kings. Though some aspects of the emergence and development of Yahwistic monotheism in postexilic times may be traced to Persian imperial policies, the influence of Persian religion can be seen, in particular, in the apparition of some dualistic tendencies in the Hebrew Bible. The Priestly writers seem thus to have been sensitive to the idea that the « good » deity cannot have created evil. The introduction of the Satan figure in some postexilic texts (cf. 1 Ch 21; Jb l) is also related to this dualistic world-view. This new theological trend was also fought by some : hence, in Is. 45.7, the affirmation that God creates evil as well as shalom must be seen as an anti-Mazdean polemic. 1. Judaïsme(s) et religion(s) perses sous les Achéménides : quels liens ? La question d'une éventuelle influence des croyances perses sur le judaïsme tel qu'il va se développer durant les ve et 1ve siècles avant notre ère est fort complexe, et ceci pour plusieurs raisons. Il est très difficile de se faire une idée claire du système religieux adopté par les souverains achéménides 1. Le débat tourne principalement

This article deals with left-headedness in compounding in some dialectal varieties of Greek, a language which is predominantly right-headed. On the basis of data stored in DComp, a dialectal database of the University of Patras containing 17,019 entries, I claim that left-headedness has resulted from the interplay of endogenous and exogenous factors. Given that left-headed compounds appear in the varieties which have been under a long-lasting Romance control, and since Romance languages are mainly left-headed, the exogenous contact factor is principally responsible for the presence of left-headedness, seen as a pattern-borrowing case, in the broad sense. Nevertheless, the phenomenon was not unknown in Ancient Greek compounding, although it applied to a much lesser extent than right-headedness. In line with the view that structural transfer is possible if there is some compatibility between languages in contact, I also assume that the old endogenous property of left-headedness has fa...

This paper reexamines feminist and transgender theory’s concepts of agency and resistance by analyzing three late antique Lives of gender-crossing saints from the Holy Land: Pelagia the Harlot, Mary of Egypt, and Susanna of Eleutheropolis. It investigates the possibilities for agency and resistance of the fictional protagonists of these hagiographic narratives against the forms of domination and the encroachments of power in the Byzantine social and religious contexts. This study contends that, despite the constraints of their situation, the subjugated individuals were capable of exercising their agency and were not passive victims of the existing social system. Even if the gender-crossing acts themselves did not undermine the conditions of oppression, albeit discursively destabilizing the societal norms of gender and sexuality, the small-scale forms of resistance of the dominated can be recovered in these accounts, notwithstanding the fragmentary and transient character of these efforts. https://www.ceeol.com/search/article-detail?id=1124460

In età classica la rappresentazione arcaica di Apollo come protettore divino delle greggi sopravvive attraverso scarsi cenni o allusioni che consistono per lo più in epiteti legati al mondo dell’allevamento. Questa specifica e primitiva connotazione di Apollo è dunque meno attestata rispetto alle descrizioni legate ad altri ambiti di competenza del dio divenuti tipici in età classica. In questo panorama un’eccezione è rappresentata dall’ "Alcesti" di Euripide, che riscopre e rimodella l’immagine di Apollo come pastore in un contesto bucolico, coerentemente con lo sfondo mitico e preclassico dell’intero dramma. Il ritratto di Apollo nella veste di pastore, reso con attributi che si discostano dall’immagine canonica del dio della musica e della poesia, costituisce un elemento di originalità che può essere attribuito alla mistione di serio e comico presente nell’ "Alcesti", dove elementi arcaici e tradizionali convivono con nuove tendenze drammatiche e musicali. In questo paper sostengo inoltre che l’ambientazione rustica e pastorale in cui il dio viene inserito nella commedia di Euripide fornisce un precedente rilevante per la reinterpretazione di Apollo Nomios in chiave idilliaca in alcuni poeti alessandrini.

O objetivo deste trabalho é analisar como a educação ambiental (EA) está sendo trabalhada no campus Porto Nacional-IFTO. Trabalho com enfoque nos discentes, para, por meio das explanações destes, sabermos se o que prescreve as Diretrizes Curriculares para a EA, Parâmetros Curriculares para o Meio Ambiente e a Lei de Diretrizes e Base da Educação (9394/96) estão sendo atendidas na perspectiva da EA. Aplicou-se um questionário cuja divisão se deu em seis etapas, perguntas proeminentemente objetivas dicotômicas. Constatou-se que a EA está sendo trabalhada numa perspectiva mínima e pouco interdisciplinaridade da temática. Assim, infere-se que há necessidade de uma intervenção voltada para uma EA mais sólida no ensino.

The currently developing telework phenomenon has many impacts on employees, one of the impacts of implementing telework is turnover intention. This research was conducted with the aim of knowing the dynamics of telework employees who tend to turnover intention. The method used in this research is a systematic literature review referring to 15 journal articles obtained from the Google Scholar, Scopus, and PubMed databases. The results of the literature review that has been carried out show that telework related to turnover intention. Several things were found that showed a link between telework and turnover intentions, including: 1) Specific job characteristics of the telework gap felt by employees are additional drivers of turnover intentions and can be mediated by jealousy and job dissatisfaction. 2) Differences in perceptions of remote work from each employee's perspective may increase feelings of envy toward remote workers and job dissatisfaction, which in turn is associated ...
