HOW CAN SHAREHOLDERS’ AGREEMENTS SHAPE CORPORATE GOVERNANCE AND DIRECTORS’ LIABILITY?

The interplay between contract and state corporate law in shaping corporate governance is not a novelty. In this article author questions the impact of private ordering through the shareholders’ agreement (further in text: SA) on corporate governance and possibly on the director’s duties and liabilities. The author argues that the SA might have far-reaching consequences for all the stakeholders and third persons as there are only a few limitations to its content, mainly referring to the mandatory rules of corporate law and general limitations of contract law. It means shareholders can impose additional rules for governance to directors, for transfer of shares, employment policy, and others. The author shall question whether SA can modify the articles of association. This article aims to reassess the balance between corporate and contract law instruments for the companies’ governance. The author argues that analyzing corporate governance without considering contractual tools, such as SA, becomes incomplete and seriously undermines rethinking fundamental principles of corporate governance, such as the issue of directors’ liability

Disarming Iraq?: the United Nations Special Commission 1991-98

After the Gulf War in 1991, the United Nations Security Council’s ‘ceasefire resolution’ obliged Iraq to destroy all weapons of mass destruction (WMD) and associated infrastructures. The United Nations Special Commission (UNSCOM) was established to oversee Iraq’s disarmament. However Iraq’s partial cooperation led to the emergence of several unresolved disarmament questions concerning Iraq’s intentions in the area of WMD. After operation Desert Fox in 1998, the disarmament regime fell apart. UNSCOM is now considered a major success of the United Nations. The case of UNSCOM and Iraq uniquely illustrates challenges and difficulties facing an effort to enforce (WMD) disarmament on a sovereign country

Were WMDs the Real Issue?: The International Community versus Iraq 1991-2003

In Resolution 687, after the Gulf War of 1991, the United Nations Security Council unanimously demanded that Iraq get rid of all weapons of mass destruction, and imposed economic sanctions as well as an intrusive inspection regime. The present study describes and analyses the developments that followed in Iraq, the evolving policy of the United States, the divisions that gradually emerged in the Security Council as to how to deal with Saddam Hussein’s regime, and the role of the western intelligence agencies

Orbital cellulitis as a vfirst sign of ethmoid sinus osteoma in children - case report and short literature review

Introduction: Orbital cellulitis is a rare condition with very dangerous complication of acute sinus infection that could potentially lead to vision loss. It is the most common complication of acute sinusitis, especially in children. On the other hand, osteoma of paranasal sinuses in pediatric patients causing orbital cellulitis is a very rare phenomenon. Case report: A 13-year-old male child was presented to our Clinic with severe frontal headache, large swelling of the upper right eyelid, proptosis, chemosis and impaired vision of the affected eye. Fiberendoscopy showed purulent discharge from both nasal cavums and mucosal inflammation which caused the narrowing of the right ostiomeatal complex as well as sphenoetmoidal recess. Computer tomography of the paranasal sinuses revealed a subperiosteal abscess localized on the superolateral orbital wall with opacified right frontal sinus and huge ethmoid sinus osteoma measuring 2.5x2x1 cm. The tumour was removed endoscopically and great care was taken not to pierce the skull base and simultaneously remove all parts of the tumour. In addition, an outer incision of 1 cm of the upper eyelid was performed. The patient’s symptoms decreased postoperatively, and the patient was released from the Clinic with significant improvement on the sixth postoperative day. Discussion: We present an extremely rare case of ethmoidal osteoma which caused orbital cellulitis in a pediatric patient. Treating such patients is very sensitive and established algorithms do not exist. We examined the available literature on the aforementioned topic. According to Chandler’s classification of orbital cellulitis, the treating of grade III or subperiosteal abscess is still a controversy. However, in our patient’s case, the cause of cellulitis was large osteoma, so surgical intervention was inevitable. An endoscopic approach gives excellent results, but maximal care must be taken in order to avoid damaging the surrounding important structures, especially in pediatric patients who have narrow nasal cavities

Istodobna pojavnost boli u području glave, lica i vrata te depresije u ratnih veterana s post-traumatskim stresnim poremećajem

This study investigated the relationship between chronic head, face and neck pain, and the level of depression in Croatian war veterans with post-traumatic stress disorder (PTSD). The presence of self-reported pain, pain on digital palpation, and pain severity in masticatory and neck muscles, temporomandibular joints and sinuses, as well as the level of depression were assessed in a group of war veterans with PTSD (n=52). Control groups consisted of war veterans without PTSD (n=50) and healthy men that were not engaged in war actions and were free from PTSD (n=50). The number of self-reported pain and number of painful sites were correlated with the level of depression. More self-reported pain and painful sites were recorded in the group of war veterans with PTSD as compared with either war veterans without PTSD or healthy men. Furthermore, PTSD patients mostly suffered from severe depression. There was a statistically significant positive correlation between all investigated pain parameters and level of depression. As the most important finding, the present study demonstrated chronic head, face and neck pain to be related to depression in PTSD patients.Svrha ovoga rada bila je istražiti odnos između kronične boli u području glave, lica i vrata te razine depresije u skupini hrvatskih ratnih veterana s post-traumatskim stresnim poremećajem (PTSP). U skupinama ratnih veterana s PTSP-om (n=52), ratnih veterana bez PTSP-a (n=50) i zdravih muškaraca koji nisu sudjelovali u Domovinskom ratu i ne boluju od PTSP-a (n=50) određivani su: samoizvještavanje boli, broj bolnih točaka i stupanj bolnosti pri digitalnoj palpaciji žvačnih mišića i mišića vrata, temporomandibularnih zglobova i sinusa. Broj samoizvještavajućih bolnih lokacija i broj bolnih točaka pri palpaciji korelirani su sa stupnjem depresije. U skupini ratnih veterana s PTSP-om zabilježeno je statistički značajno više samoizvještavajućih bolnih lokacija i više bolnih točaka pri palpaciji nego u skupinama ratnih veterana bez PTSP-a i zdravih muškaraca. Bolesnici s PTSP-om bili su uglavnom visoko depresivni. Utvrdili smo statistički značajnu pozitivnu korelaciju između svih istraživanih parametara boli i stupnja depresivnosti. Glavni zaključak ovoga istraživanja je da je kronična bol u području glave, lica i vrata povezana s depresijom u bolesnika s PTSP-om

Utjecaj sekundarnog savijanja na rast pukotina u orebrenim panelima

Eksperimentalni uzorci ploče i orebrenog panela sa središnjom pukotinom podvrgnuti su cikličkom vlačnom opterećenju. U orebrenim panelima opterećenima na vlak javljaju se izvan ravninske deformacije s lokalnim savijanjem, kao posljedica geometrijskoga ekscenctriciteta nastalog propagacijom pukotina. Faktor sekundarnog savijanja sbf definiran je kao odnos membranskog naprezanja i naprezanja uslijed savijanja u okolici vrha pukotine. Uveden je postupak za simulaciju životnog vijeka konstrukcije temeljen na integraciji Parisove jednadžbe, pri čemu se lokalno savijanje uzima u obzir. Vrijednost faktora intenzivnosti naprezanja, KI, na vanjskoj površini ploče, na kojoj se javlja pozitivno naprezanje uslijed savijanja, izračunava se na temelju membranske vrijednosti faktora intenzivnosti naprezanja utvrđenog metodom konačnih elemenata koristeći programski paket ANSYS i sbf-faktora. Simulirani životni vijek za orebreni panel nešto je kraći od eksperimentalno utvrđenoga životnog vijeka, što upućuje na konzervativnost simulacijske metode
