    Notizen: A stylized fact of empirical work on the relationship of wages and unemployment using macro data for European countries is a combination of strong autocorrelation of wages and a significant negative long-run relationship of wages and unemployment. However, this view is challenged by empirical work relying on regional or micro data providing evidence for an instantaneous adjustment of wages to variations in the level of unemployment. Exploiting regional panel data for West Germany, we show that, at least for the years 1990–94, regional and macro data mirror the same phenomenon. Our results are broadly consistent with the observed increase in the natural rate of unemployment in Germany.

    Notizen: We present an 84-year-old Caucasian man (Fitzpatrick classification: skin type II) with microcystic adnexal carcinoma (MAC) on his left cheek and a 15-year history of recurrent squamous cell carcinoma (SCC) of the head, treated with numerous surgical interventions and multiple palliative 60-Gy radiation therapy.In 1996, the patient developed a nontender, indurated, irregularly marked, erythematous lesion on his left cheek (1.5 × 1 cm). Furthermore, the patient suffered from radiodermatitis due to previous radiotherapy ( 〈link href="#f2-1"〉Fig. 1). Punch biopsy and a subsequent wedge excision showed features of both SCC and eccrine carcinoma. Histopathologic and immunohistochemical tests of the tumor revealed a diagnosis of MAC. The patient underwent Mohs' micrographically controlled surgery to obtain tumor-free peripheral soft tissue margins. There was no evidence of any lymphatic invasion or distant metastasis in the physical and laboratory examination. So far, the patient has not developed any recurrences.〈figure xml:id="f2-1"〉1〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD841-2:IJD_841_f2-1"/〉Clinical picture of MAC showing features of radiodermatitisFollowing excision, the biopsy specimen (4 × 2.6 × 1 cm) was fixed in Dubosq-Brazil and routinely processed for staining with hematoxylin and eosin. The neoplasm extended into the subcutaneous tissue with rare connection to the overlying epidermis ( 〈link href="#f2-2"〉Fig. 2). Follicular cysts with amorphous eosinophilic keratin and comma-like tails of aggregates of epithelial cells were a prominent feature ( 〈link href="#f2-3"〉Fig. 3). Perineural invasion was evident, but there were only a very few mitotic figures. Immunohistochemistry on paraffin-embedded tissue blocks was performed, showing strong labeling on dilated ducts for carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA) in the lumina of tumor cells, and positive staining for anticytokeratin KL1 (55–57 kDa) and S-100 protein. The latter was negative in ductal structures, but stained dendritic cells.〈figure xml:id="f2-2"〉2〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD841-2:IJD_841_f2-2"/〉Panoramic view of the tumor demonstrating poorly circumscribed and deeply infiltrative growth patterns.

    Notizen: The two sulfido-bridged dirhenium complexes bis(μ-4-methoxyphenylsulfido-S)bis(tetracarbonylrhenium), [Re2(C7H7OS)2(CO)8], and bis(μ-naphthylsulfido-S)bis[tricarbonyl(dicyclohexylphosphane)rhenium], [Re2(C12H23P)2(C10H7S)2(CO)6], show different geometries of the common Re2S2 core. The 4-methoxyphenyl derivative has crystallographic \overline 1 symmetry and the naphthyl derivative has C2 symmetry. This results from intramolecular repulsion due to different substitution patterns at the Re and S atoms.

    Notizen: Abstract We study the matrices, reduced matrices and algebras associated to the systems SAℒT of structural annotated logics. In previous papers, these systems were proven algebraizable in the finitary case and the class of matrices analyzed here was proven to be a matrix semantics for them. We prove that the equivalent algebraic semantics associated with the systems SAℒT are proper quasivarieties, we describe the reduced matrices, the subdirectly irreducible algebras and we give a general decomposition theorem. As a consequence we obtain a decision procedure for these logics.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung: Ziel der vorliegenden Untersuchung war die Evaluierung der sagittalen, vertikalen und transversalen Veränderungen der Eckzahnposition und deren möglicher Zusammenhang mit einem Rezidiv des unteren Frontengstandes. Aus einem Langzeitnachuntersuchungsgut durchschnittlich 15,7 ± 4,4 Jahre nach Behandlungsabschluss wurden die zum Untersuchungsdatum vollbezahnten Patienten selektiert. Die End- und Nachuntersuchungsmodelle von 117 Patienten wurden hinsichtlich der oben genannten Parameter vermessen und die Ergebnisse statistisch ausgewertet. Es zeigte sich eine Abnahme der interkaninen Distanz zwischen Abschluss- und Nachuntersuchungszeitpunkt, die Neigung der unteren Eckzahnachsen nahm in der Transversalen nach lingual hin zu. Es konnte auch ein statistisch nachweisbarer Zusammenhang zwischen oberer und unterer Eckzahnneigung festgestellt werden. Des Weiteren kam es zu einer Zunahme des unteren Engstandes und zu einer Abnahme der interkaninen Distanz in Abhängigkeit von den zuvor genannten Befunden. Der rezidivierende Frontengstand hat eine multifaktorielle Genese. Die beschriebenen Ergebnisse zeigen eine Mitbeteiligung der Eckzähne. Insbesondere funktionelle Ursachen könnten hier maßgeblichen Einfluss haben und sollten in die therapeutischen Überlegungen mit einbezogen werden.
    Notizen: Abstract: The aim of the present study was to evaluate sagittal, vertical and transverse changes in canine position and a possible correlation with relapse of lower anterior crowding. From a sample with a long-term follow-up of 15.7 ± 4.4 years after treatment, patients with a full dentition were enrolled in the study. Post-treatment and long-term follow-up casts of 117 patients were measured and statistically analyzed. A decrease in intercanine width was found between post-treatment and long-term follow-up records, with more lingual inclination of the mandibular canine axis in the transverse plane. There was a significant correlation between maxillary and mandibular canine inclination. Concomitant changes were an increase in lower anterior crowding and a decrease in mandibular intercanine width. Relapse of anterior crowding has a multifactorial etiology. The results of this study suggest a possible influence of the canines. Functional causes in particular might have a profound influence and should be considered during treatment planning.

    Notizen: Abstract This paper investigates in detail the design parameters of the two mostprominent US cap-and-trade permit program – the US EPA Sulfur AllowanceTrading Program and the South Californian Regional Clean Air IncentivesMarket (RECLAIM). In contrast to expectations the two programs turn out to be rather different in several important design parameter choices.Common elements emerge primarily in the existence of an ambitious, quantifiedenvironmental target, mandatory use of stringent emission monitoring methodsand stiff penalties for non-compliance, coexisting command-and-controlregulations, the creation of a competitive permit market structure, andsome distributional concessions in the initial permit allocation. Generalizing from these common features we find that provisions to assurepolitical acceptance, functional interdependencies and overlapping regulation are the most important influences on the design of applied cap-and-trade permit programs.
