Hippasa haryanensis Arora & Monga 1994
No full textHippasa haryanensis Arora & Monga, 1994, nomen nudum Hippasa haryanensis Arora & Monga, 1994: 74, figs 5–8 (♂ ♀). Type material. Holotype ♀ from INDIA: Haryana: Hisar: Pigeon pea fields at Research Farm of Chaudhary Charan Singh (CCS) Haryana Agricultural University, 28 August 1989, P. Arora leg., repository unknown (no register number specified), not examined. Paratypes 10 ♂♂, 30 ♀♀, with the same data as holotype except 15 July 1989, 28 August 1989 and 20 September 1989, not examined. Allotype 1 ♂, with the same data as holotype, not examined. Remarks. We were unable to examine the types of this species as no information is available about its repository (Arora & Monga 1994), and thus should be considered nomen nudum in the terms of art. 16.4 of the International Code of Zoological Nomenclature (ICZN 1999). The original description and genitalic illustrations of this smallsized species (body length: male 5.52, female 6.45) are poor and insufficiently informative to recognize it (Arora & Monga 1994: figs 5, 8). The original description of the female mentions that the sternum lacks the mid-longitudinal band (Arora & Monga 1994), indicating it may not be a member of Hippasa. Moreover, the median epigynal septum illustrated for this species (Arora & Monga 1994: fig. 8) indicates that it may be a member of either Ovia Sankaran, Malamel & Sebastian, 2017 or Trochosa C.L. Koch, 1847. The novelty and taxonomic placement of this species remain unchallenged until examination of its types or topotype specimens.Published as part of SANKARAN, PRADEEP M. & CALEB, JOHN T.

È dell’informatica il fin la meraviglia. Metafore per la sicurezza e sicurezza delle metafore
No full textL'informatica consiste sostanzialmente nella produzione di metafore coerenti, comprensibili
(agli utenti e ai programmatori), adattabili facilmente e sicure. Quest'ultimo è un obiettivo
particolarmente difficile: le metafore per la sicurezza possono essere ingannevoli o superficiali e la valutazione della loro effettiva sicurezza è piena di trappole insidiose e astrazioni imperfette che i malintenzionati possono sfruttare a loro vantaggio. In effetti, occorre sempre
tener presente che le metafore dell'informatica predicano sul mondo della computazione, della manipolazione simbolica e solo di riflesso sull'universo in cui agiamo. Per valutare l'efficacia della protezione sarà dunque sempre necessario considerare con attenzione la relazione
fra i due mondi ed evitare di lasciarsi trasportare acriticamente dal portato metaforico
On the impact of localization data in wireless sensor networks with malicious nodes
No full textThe knowledge of node positions is a core concept in any Wireless Sensor Network context. Several localization algorithms were devised, but secure localization of sensor nodes is still a challenging task to achieve with a high level of performance. In fact, location information might be the target of different kinds of malicious attacks and several secure localization approaches were proposed. In this paper we analyze the impact of false data in a secure localization algorithm, known as Verifiable Multilateration. We found that the strategy used to compute the positions of nodes might have an impact both on the computational effort needed to achieve acceptable measures and the precision of the detection of malicious nodes
The multiple facets of integrity in business and management
No full textIn this chapter, as a backdrop to the contributions made by the researchers in this volume, we first provide a brief sketch of the variety of ways integrity has been conceptualized and analyzed in the Management and Business Ethics literature. We then preview the individual chapters included in the book
