La tesi ha ad oggetto l’analisi delle fattispecie statutarie di riscatto azionario nella s.p.a. dopo la riforma del 2003. Quest’ultima ha anzitutto introdotto una disciplina destinata genericamente a tutte le ipotesi statutarie in cui si preveda un potere di riscatto a vantaggio della società o di soci (art. 2437-sexies c.c.). L’esegesi di tale disciplina e l’indagine sui possibili utilizzi, in chiave funzionale, delle azioni riscattabili costituiscono il primo obiettivo del lavoro. Per quanto attiene al c.d. riscatto obbligatorio di azioni si è invece assistito alla sola emersione di alcune specifiche ipotesi legali (ad es., art. 2355-bis, comma 2°, c.c.). Si dimostra, tuttavia, che non sussistono ragioni per negare, in linea generale, la possibilità per l’autonomia privata di avvalersi di tale meccanismo di riscatto in ipotesi diverse da quelle espressamente tipizzate. La ricostruzione della disciplina delle fattispecie statutarie atipiche di riscatto obbligatorio e la loro valorizzazione quali peculiari strumenti di disinvestimento dalla società - con caratteristiche non del tutto sovrapponibili al recesso convenzionale - costituiscono il secondo indirizzo d’analisi seguito nello sviluppo della tesi. Nell’affrontare i vari profili trattati, si tiene in attenta considerazione la disciplina comunitaria in tema di riscatto azionario, nonché il dato comparatistico. / The scrutiny of the rules concerning the redemption of shares in the Italian public companies (s.p.a.) after the statutory reform of 2003 is the main focus of the thesis. On the one hand , the reform has introduced a general discipline concerning the provisions of the bylaws that provide a call for redemption of issued shares (art. 2437-sexies c.c.). Under this general aspect the first goal of the work is to analyze both the new general discipline concerning the callable redeemable shares and their functional use. On the other hand, the reform has ruled only a few typical hypothesis of the so called mandatory redemption (for example, art. 2355, par. 2 , c.c.). However, the work points out that there is no reason why to deny private autonomy to use this second form of redemption in cases other than those explicitly ruled. So, the second objective of the thesis is to reconstruct the discipline of the otherwise agreements concerning the matter of the mandatory redemption provisions. The thesis points out that the puttable redeemable shares represent a tool for divestment from public companies with autonomous characteristics in respect to the withdrawal from corporation clauses. To address the various issues considered, are taken into careful consideration both the EU rules concerning share redemption, and the comparative law perspective .

Wireless Sensor Networks (WSNs) are deployed for monitoring in a range of critical domains (e.g., health care, military, critical infrastructure). Accordingly, these WSNs should be resilient to attacks. The current approach to defending against malicious threats is to develop and deploy a specific defense mechanism for a specific attack. However, the problem with this traditional approach to defending sensor networks is that the solution for one attack (i.e., Jamming attack) does not defend against other attacks (e.g., Sybil and Selective Forwarding). This work addresses the challenges with the traditional approach to securing sensor networks and presents a comprehensive framework, Di-Sec, that can defend against all known and forthcoming attacks. At the heart of Di-Sec lies the monitoring core (M-Core), which is an extensible and lightweight layer that gathers information and statistics relevant for creating defense modules. Along with Di-Sec, a new user-friendly domain-specific language was developed, the M-Core Control Language (MCL). Using the MCL, a user can implement new defense mechanisms without the overhead of learning the details of the underlying software architecture (i.e., TinyOS, Di-Sec). Hence, the MCL expedites the development of sensor defense mechanisms by significantly simplifying the coding process for developers. The Di-Sec framework has been implemented and tested on real sensors to evaluate its feasibility and performance. Our evaluation shows that Di-Sec is feasible on today’s resource-limited sensors and has a nominal overhead. Furthermore, we illustrate the functionality of Di-Sec by implementing four detection and defense mechanisms for attacks at various layers of the communication stack.

For a period about two hundred and thirty years before 479 BC. Jing holds supreme power over all neighbouring hostile countries and protected emperor Zhou. Only until Han¡MZhao¡MWei started civil strife and Jing was torn apart, then did Zhou's empire fall. The article below is to discuss how Jing came to power with the setup of Zhong Jun Shuai¡Aand several political and civil issues raised during that period of time.
