Los enigmas en El libro de los cuentos de Rafael Boira

El libro de los cuentos, de Rafael Boira, fue uno de los muchos que se publicaron como esparcimiento en el siglo xix. Es una recopilación de composiciones jocosas menores, en prosa, salvo algunas en verso; entre éstas hay más de un centenar de enigmas o adivinanzas en quintillas cuya autoría no nos reveló. El autor de las adivinanzas es Cristóbal Pérez de Herrera (1618). Aunque como autor generalmente es original, copia o imita algunas adivinanzas preexistentes en la tradición oral o culta. Boira copió de manera literal muchas adivinanzas de este autor, aunque escribió otras con alteraciones, mayores o menores, quizás por recordarlas de memoria. "Las enigmas", de Pérez de Herrera, fueron muy divulgados anónimamente: pasaron a la tradición escrita pero también se recogieron, y aún es así hoy en día, de modo oral. Lo cierto es que también están ya presentes en la tradición oral algunas versiones tal como Boira las alteró. Incuestionablemente, los enigmas cultos han pasado a la tradición oral en el ámbito de la cultura hispana. Herrera y Boira son dos marcas en este camino de popularización

Relative income, happiness, and utility : an explanation for the Easterlin paradox and other puzzles

The well-known Easterlin paradox points out that average happiness has remained constant over time despite sharp rises in GNP per head. At the same time, a micro literature has typically found positive correlations between individual income and individual measures of subjective well-being. This paper suggests that these two findings are consistent with the presence of relative income terms in the utility function. Income may be evaluated relative to others (social comparison) or to oneself in the past (habituation). We review the evidence on relative income from the subjective well-being literature. We also discuss the relation (or not) between happiness and utility, and discuss some nonhappiness research (behavioral, experimental, neurological) related to income comparisons. We last consider how relative income in the utility function can affect economic models of behavior in the domains of consumption, investment, economic growth, savings, taxation, labor supply, wages, and migration.

Stronger difficulty notions for client puzzles and denial-of-service-resistant protocols

Client puzzles are meant to act as a defense against denial of service (DoS) attacks by requiring a client to solve some moderately hard problem before being granted access to a resource. However, recent client puzzle difficulty definitions (Stebila and Ustaoglu, 2009; Chen et al., 2009) do not ensure that solving n puzzles is n times harder than solving one puzzle. Motivated by examples of puzzles where this is the case, we present stronger definitions of difficulty for client puzzles that are meaningful in the context of adversaries with more computational power than required to solve a single puzzle. A protocol using strong client puzzles may still not be secure against DoS attacks if the puzzles are not used in a secure manner. We describe a security model for analyzing the DoS resistance of any protocol in the context of client puzzles and give a generic technique for combining any protocol with a strong client puzzle to obtain a DoS-resistant protocol.

Re-Presenting/Representing Melbourne: A literary and cultural analysis of Melbourne’s inner city and outer suburbs in contemporary fiction

This article provides an overview of a research project investigating contemporary literary representations of Melbourne’s inner and outer suburban spaces. It will argue that the city represented by local writers is an often more complex way of envisioning the city than the one presented in public policy and cultural discourses. In this view, the writer’s vision of a city does not necessarily override or provide a “truer’ account but it is in the fictional city where the complexity of the everyday life of a city is most accurately portrayed. The article will also provide an overview of the theoretical framework for reading the fictional texts in this way, examining how Soja’s concept of Thirdspace (2006) provides a place to engage “critically with theoretical issues, while simultaneously being that space where the debate occurs” (Mole 2008: 3).

Defending web services against denial of service attacks using client puzzles

The interoperable and loosely-coupled web services architecture, while beneficial, can be resource-intensive, and is thus susceptible to denial of service (DoS) attacks in which an attacker can use a relatively insignificant amount of resources to exhaust the computational resources of a web service. We investigate the effectiveness of defending web services from DoS attacks using client puzzles, a cryptographic countermeasure which provides a form of gradual authentication by requiring the client to solve some computationally difficult problems before access is granted. In particular, we describe a mechanism for integrating a hash-based puzzle into existing web services frameworks and analyze the effectiveness of the countermeasure using a variety of scenarios on a network testbed. Client puzzles are an effective defence against flooding attacks. They can also mitigate certain types of semantic-based attacks, although they may not be the optimal solution.

Efficient modular exponentiation-based puzzles for denial-of-service protection

Client puzzles are moderately-hard cryptographic problems neither easy nor impossible to solve that can be used as a counter-measure against denial of service attacks on network protocols. Puzzles based on modular exponentiation are attractive as they provide important properties such as non-parallelisability, deterministic solving time, and linear granularity. We propose an efficient client puzzle based on modular exponentiation. Our puzzle requires only a few modular multiplications for puzzle generation and verification. For a server under denial of service attack, this is a significant improvement as the best known non-parallelisable puzzle proposed by Karame and Capkun (ESORICS 2010) requires at least 2k-bit modular exponentiation, where k is a security parameter. We show that our puzzle satisfies the unforgeability and difficulty properties defined by Chen et al. (Asiacrypt 2009). We present experimental results which show that, for 1024-bit moduli, our proposed puzzle can be up to 30 times faster to verify than the Karame-Capkun puzzle and 99 times faster than the Rivest et al.'s time-lock puzzle.

Creative writing, literary studies, and global thinkers

There has been growing interest in how to make tertiary education more global and international not only in context but, also, in approach and methodology. One area of the education sector that has come under specific focus is the higher education sector curriculum and its design. This paper addresses the process of ‘internationalising’ the curriculum through the specific example of designing a new literary unit for undergraduate students, mainly literary studies and creative writing students. The literary unit entitled: Imagining the Americas: Contemporary American Literature and Culture, has the added complexity of being a unit about national fiction. This paper explores the practical problems and obstacles encountered in setting up this unit while using a framework of internationalisation. The case study examines the practicalities in implementing strategies that reflect the overall objective of creating global thinkers within a tertiary environment.

The role of strategic intelligence in anticipating transnational organised crime: A literary review

Transnational Organised Crime (TOC) has become a focal point for a range of private and public stakeholders. While not a new phenomenon, the rapid expansion of TOC activities and interests, its increasingly complex structures and ability to maximise opportunity by employing new technologies at a rate impossible for law enforcement to match complicates law enforcement’s ability to develop strategies to detect, disrupt, prevent and investigate them. In an age where the role of police has morphed from simplistic response and enforcement activities to one of managing human security risk, it is argued that intelligence can be used to reduce the impact of strategic surprise from evolving criminal threats and environmental change. This review specifically focuses on research that has implications for strategic intelligence and strategy setting in a TOC context. The review findings suggest that current law enforcement intelligence literature focuses narrowly on the management concept of intelligence-led policing in a tactical, operational setting. As such the review identifies central issues surrounding strategic intelligence and highlights key questions that future research agendas must address to improve strategic intelligence outcomes, particularly in the fight against TOC.

Re/presenting readings of the indigenous literary terrain

In this study I investigate the spectrum of authoring, publishing and everyday reading of three texts - My Place (Morgan 1987), Jandamarra and the Bunuba Resistance (Pedersen and Woorunmurra 1995) and Carpentaria (Wright 2006). I have addressed this study within the field of production and consumption, utilising amongst others the work of Edward Said (1978, 1983) and Stanley Fish (1980). I locate this work within the holism of Kombu-merri philosopher, Mary Graham's 'Aboriginal Inquiry' (2008), which promotes self-reflexivity and a concern for others as central tenets of such inquiry. I also locate this work within a postcolonial framework and in recognition of the dynamic nature of that phenomenon I use Aileen MoretonRobinson's (2003) adoption of the active verb, "postcolonising"(38). In apprehending selected texts through the people who make them and who make meaning from them - authors, publishers and everyday readers, I interviewed members of each cohort within a framework that recognises the exercise of agency in their respective practices as well as the socio-historical contexts to such textual practices. Although my research design can be applied to other critical arrangements of texts, my interest here lies principally in texts that incorporate the subjects of Indigenous worldview and Indigenous experience; and in texts that are Indigenous authored or Indigenous co-authored.

The relationship between lower intelligence, crime and custodial outcomes : a brief literary review of a vulnerable group

The relationship between intellectual functioning and criminal offending has received considerable focus within the literature. While there remains debate regarding the existence (and strength) of this relationship, there is a wider consensus that individuals with below average functioning (in particular cognitive impairments) are disproportionately represented within the prison population. This paper focuses on research that has implications for the effective management of lower functioning individuals within correctional environments as well as the successful rehabilitation and release of such individuals back into the community. This includes a review of the literature regarding the link between lower intelligence and offending and the identification of possible factors that either facilitate (or confound) this relationship. The main themes to emerge from this review are that individuals with lower intellectual functioning continue to be disproportionately represented in custodial settings and that there is a need to increase the provision of specialised programs to cater for their needs. Further research is also needed into a range of areas including: (1) the reason for this over-representation in custodial settings, (2) the existence and effectiveness of rehabilitation and release programs that cater for lower IQ offenders, (3) the effectiveness of custodial alternatives for this group (e.g. intensive corrections orders) and (4) what post-custodial release services are needed to reduce the risk of recidivism.
