Respect for persons and for cultures as a basis for national and global citizenship

After distinguishing several ways in which the notion of the moral roots of citizenship and citizenship education can be understood, this paper focuses on the question ‘Is there some underlying attitude that citizens should have towards their fellow citizens?’. It argues for respect, rather than love or care, as being the appropriate attitude, in part on the grounds that the emphasis on respect helps to make moral sense of the notion of global citizenship. The rest of the paper argues that while understanding a person’s cultural background is necessary to respecting the person, there are two further connections between respect and culture. First, respect itself is in part a cultural phenomenon. Secondly, there is a case for saying that persons should respect, not only other persons, but cultures as such. It is argued that this case is flawed in its presupposition that distinct cultures can be identified. What is needed, rather, is respect for human cultural contexts in all their diversity

Smooth norms and approximation in Banach spaces of the type C(K)

We prove two theorems about differentiable functions on the Banach space C(K), where K is compact. (i) If C(K) admits a non-trivial function of class C^m and of bounded support, then all continuous real-valued functions on C(K) may be uniformly approximated by functions of class C^m. (ii) If C(K) admits an equivalent norm with locally uniformly convex dual norm, then C(K) admits an equivalent norm which is of class C^infty (except at 0)

The impace of custom ROM backups on android external storage erasure

The Android operating system is the current market leader on mobile devices such as smartphones and tablet computers. The core operating system is open source and has a number of developers creating variants of this operating system. These variants, often referred to as custom ROMs are available for a wide number of mobile devices. Custom ROMs provide a number of features, such as enhanced control over the operating system, variation in user interfaces and so on. The process of installing custom ROMs is often accomplished through the use of a ROM manager application. Such applications often provide mechanisms to back up the contents of the mobile device prior to upgrade. This mechanism is utilised in the case of a failed update to restore the device to its previous functional state. Backups produced in this manner are often stored in on an external media such as a micro-SD card.In the conducted research we evaluated devices inbuilt data erasure mechanisms within the context of erasure of backups produced by ROM managers. It was found that simply using the devices Format External / SD function is not an effective means of completely erasing these backups. Once recovered, these backups offer a quick source of information that a potential attacker could carve to retrieve user files such as media transferred to the external or from applications. Although the same files could be recovered from an image of the external storage itself, the carving process is more efficient than traditional carving methods

On Efimov spaces and Radon measures

We give a construction under CH of an infinite Hausdorff compact space having no converging sequences and carrying no Radon measure of uncountable type. Under ? we obtain another example of a compact space with no convergent sequences, which in addition has the stronger property that every nonatomic Radon measure on it is uniformly regular. This example refutes a conjecture of Mercourakis from 1996 stating that if every measure on a compact space K is uniformly regular then K is necessarily sequentially compact
