On the cost of delayed currency fixing announcements
No full textIn Foreign Exchange Markets vanilla and barrier options are traded frequently. The market standard is a cutoff time of 10:00 a.m. in New York for the strike of vanillas and a knock-out event based on a continuously observed barrier in the inter bank market. However, many clients, particularly from Italy, prefer the cutoff and knock-out event to be based on the fixing published by the European Central Bank on the Reuters Page ECB37. These barrier options are called discretely monitored barrier options. While these options can be priced in several models by various techniques, the ECB source of the fixing causes two problems. First of all, it is not tradable, and secondly it is published with a delay of about 10 - 20 minutes. We examine here the effect of these problems on the hedge of those options and consequently suggest a cost based on the additional uncertainty encountered. --exotic options,currency fixings
Adenyl cyclases and cAMP in plant signaling - Past and present
No full textIn lower eukaryotes and animals 3'-5'-cyclic adenosine monophosphate (cAMP) and adenyl cyclases (ACs), enzymes that catalyse the formation of cAMP from ATP, have long been established as key components and second messengers in many signaling pathways. In contrast, in plants, both the presence and biological role of cAMP have been a matter of ongoing debate and some controversy. Here we shall focus firstly on the discovery of cellular cAMP in plants and evidence for a role of this second messenger in plant signal transduction. Secondly, we shall review current evidence of plant ACs, analyse aspects of their domain organisations and the biological roles of candidate molecules. In addition, we shall assess different approaches based on search motifs consisting of functionally assigned amino acids in the catalytic centre of annotated and/or experimentally tested nucleotide cyclases that can contribute to the identification of novel candidate molecules with AC activity such as F-box and TIR proteins. 2010 Gehring; licensee BioMed Central Ltd

Private Equity und Familienunternehmen: eine Untersuchung unter besonderer Berücksichtigung deutscher Maschinen- und Anlagenbauunternehmen
No full textDespite the common view that there is inherently a relationship of confliction, it is now impossible to imagine the financing of family-owned enterprises in Germany without the alternative method of Private Equity financing. Based on a survey on Private Equity in family owned companies specialising in the mechanical engineering sector, this working paper identifies that Private Equity in general is not as unwanted as once assumed. Overall more than 3/4 of the surveyed companies do not exclude investment capital. However, the study demonstrates that the time of large buy-outs is arguably up, and minority capital has now come into vogue. This working paper examines, from the viewpoint of the managing directors of the studied companies, the conceptions and beliefs held by such persons about Private Equity. Generally speaking, besides loss of control, managing directors primarily fear Private Equity because of exaggerated returns on investment at the expense of the long-term development of the company. On the other hand, this paper also highlights that managing directors expect that Private Equity can have a positive element as it can enable bank independence, especially at a time when it becomes increasingly difficult to maintain creditworthiness. Further, this paper analyses the relationship between the managing director of the family enterprise and the Private Equity investor. Because of the special situation of the managing director in a family owned company, trust between that person and the Private Equity investor is one of the most important factors. If there is a lack of trust the business relation is troubled from the start. --Private equity,buyout,family owned enterprises,minority capital,credit crisis,MBO,MBI,return on investments,LBO,leveraged finance,M&A
Technisches Nichtwissen
No full textDas Nichtwissen ist in aller Munde. Von Nichtwissenskulturen in der zweiten oder reflexiven Moderne ist die Rede, von Agnotologie als neuem Forschungszweig, von wicked problems und ihren clumsy solutions. Wo Nichtwissen sich durch Komplexitätssteigerung unwiderruflich im zu Wissenden einnistet, fordert es als Grenze, Schranke und Kehrseite des Wissens die sogenannte Wissensgesellschaft heraus. Vor allem Risikopotentiale und Gefahren kommen hier in den Blick, von denen wir gerade genug wissen, um Wissensansprüche zu formulieren, die sich womöglich nie einlösen lassen.
Das klassisch erkenntnistheoretische Problem: „Was können wir wissen?“ steht heute in einem Spannungsverhältnis zu der wissenspolitischen Frage: „Was müssen wir wissen?“ Was wir wissen müssen, ist einerseits so viel wie nötig, wenn es um Fragen von Sicherheit und Gesundheit geht – andererseits aber so wenig wie möglich, wenn es in Alltag, Wirtschaft oder Wissenschaft darauf ankommt, Wissen an technische Systeme oder Expertenkulturen zu delegieren.
Bezeichnet politisch handlungsorientiertes und wissenschaftliches Nichtwissen zunächst ein Defizit, ist technisches Nichtwissen gleichermaßen erstrebenswert und problematisch. Einige, die Technik für angewandtes Wissen halten, mögen darin eine contradictio in adjecto sehen, manche sich um eine dem technischen Nichtwissen geschuldeten Technikfeindlichkeit sorgen, andere daraus die nötige Demut gegen verstiegene Allmachtsphantasien beziehen, während ihre Gegenspieler von Maschinen träumen, die über den Horizont intellektueller Nachvollziehbarkeit immer weiter hinauseilen.
