When Corporate Governance crosses the firm borders: family firms in local productive systems

The family involvement in firms is observable is most economies around the world, although there are significant differences among these countries, not only regarding its predominance in these economies, but also in what refers to the levels of involvement of the family in business. This research aims at understanding the family-based firms’ management when compared to non family based, with particular regards to the forms of corporate governance. This analysis is based on case studies and on secondary data found in the literature to support the findings from the empirical research. The data was collected via face to face in-depth interviews with entrepreneurs from the furniture and the events organisation industries (where the family is predominantly present in the furniture but not on the events organisation industry) and with industry and regional business associations. The case studies used in this research allowed the comparison between the Portuguese firms when the family plays an important role in business and those in which the family is absent. It has been found that there are important differences in businesses in countries/industries/local productive systems in which the family is seen as a dominant institution in the society (where businesses are based on strong ties; there is a harmonious relationship between the family members; and the family is accepted locally and dominates the firm organization) and on situations in which the family plays a more marginal role in the society. In fact, the family brings special characteristics to the business, in terms of management, corporate governance, inter and intra firm relationships and succession. Our findings confirm other empirical studies’ results found in the literature. Thus, this article provides a discussion on the factors that play a role in the form of corporate governance structure in family firms highlighting the pros and cons of organising the firm around the family.

Early patterns of recovery from disturbance in intertidal algal assemblages: consistency across regions within a marine province

The importance of disturbance and the subsequent rate and pattern of recovery has been long recognised as an important driver of community structure. Community recovery is affected by processes operating at local and regional scales yet the examination of community level responses to a standardised disturbance at regional scales (i.e. among regions under different environmental conditions) has seldom been attempted. Here, we mechanically disturbed rocky intertidal lower shore algal dominated assemblages at three locations within each of three different regions within the Lusitanian biogeographical province (Azores, northern Portugal and the Canary Islands). All organisms were cleared from experimental plots and succession followed over a period of 12 months at which time we formally compared the assemblage structure to that of unmanipulated controls. Early patterns of recovery of disturbed communities varied among regions and was positively influenced by temperature, but not by regional species richness. Different components of the assemblage responded differently to disturbance. Regional differences in the relative abundance and identity of species had a key influence on the overall assemblage recovery. This study highlights how regional-scales differences in environmental conditions and species pool are important determinants of recovery of disturbed communities.

Fin de partie: l'infini recommencement de rien

Dans Fin de partie, Beckett se révèle de nouveau un maître du théâtre de l’âme, mais d’une façon pas du tout conventionnelle. On doit classer cette pièce dans l’antithéâtre parce qu’elle manque d’intrigue, il n’y a que de situations cycliques toujours répétées, le temps ne veut pas passer, c’est plutôt un moment éternel, les personnages manquent de consistance et d’individualité : ils sont davantage des incarnations d’attitudes humaines, et ils parlent un langage décousu, un bourdonnement dépourvu de sens. Bien que tous ces aspects contribuent à l’ambiguïté de la pièce, rien n’y est laissé au hasard : tout sert à communiquer l’incommunicable. La scène se passe dans un lieu clos, avec une lumière crépusculaire qui suggère la fin du jour. Les personnages et les objets se trouvent dans des poubelles (Nagg et Nell) ou couverts par des draps : peu à peu, les objets et les personnages se dévoilent d’une façon fragmentée. C’est Clov qui nous dit qu’il s’agit de la fin de quelque chose, mais déjà le décor, la lumière, la déchéance physique des personnages et les dialogues à peine esquissés suggèrent un stage final qui n’en finit plus, qui devient un moment éternel, car la mort, elle non plus, ne se présente pas comme une solution pour le problème de notre existence absurde. Et nous voilà de nouveau face à face avec l’absurdité de la condition humaine, où l’homme se sent privé de toute certitude et incapable de découvrir un sens à son existence. Le tragique de la condition humaine, et le désir de lui mettre fin est le fil conducteur de Fin de partie. Les personnages montrent tout au long de la pièce que la condition humaine est intolérable et qu’ils sont écrasés par la routine et l’ennui. Ils se sentent perdus et abandonnés par un dieu quiconque, un monstre qui a créé la nature humaine. La vie est une pile de moments infernaux ; tout le monde est dans l’attente de quelqu’un ou d’un événement qui puisse changer son cours. Mais rien ne change, les personnages sont trop passifs – Clov se prépare pour son voyage, cependant, au lieu de partir, il reste là, immobile, jusqu’à la fin. Mais c’est juste pour ce danger que Beckett veut nous alerter : si nous ne faisons pas usage de notre liberté en nous recréant par une succession de choix, nous serons damnés, c’est-à-dire, condamnés à vivre dans le désespoir, le néant, l’absurde – la vie sera toujours un infini recommencement de rien.

Connaissances stratigraphiques sur la base du Mésozoique portugais

In Portugal, the Mesozoic lower part is principally composed of conglomeratic, arenitic and pelitic deposits, which are here and there associated with carbonates rocks and evaporites. The Germanic Triassic succession is not observed. The Muschelkalk facies do not exist. Carbonates formation, and some thick evaporites deposits (Keuper facies) are of early Jurassic in age. The thick red beds accumulations deposited in a continental environment are Triassic. In Coimbra area the oldest palynomorphs found are Camian-Norian. In South Portugal (Algarve), the triassic serie must be more complete with a lower Triassic rich in Stegocephales bone-beds.

Les acanthopleurocératinés portugais et leurs relations avec les formes subboréales

The evolution of the Portuguese Acanthopleuroceratinae is similar to the celto-souabe succession such as it was described in the collects of the Cottards (Cher, France). A subspecies of one of the oldest Acanthopleuroceras (A. carinatum atlanticum) is abundant in the lower part of the Portuguese Ibex zone; this form is described here. The species is recognized in France by several nuclei associated with A. arietiforme (Cottards-22). Generally the similarity between the successive French and Portuguese populations (A. maugenesti, A. valdani, A. alisiense, junior synonym of A. lepidum TUTCHER and TRUEMAN, 1925), is very good. This fact suggests their specific identity. It is typical for A. lepidum of which the greatest populations allow the biometric comparaisons. In Portugal, the mesogean Tropidaceras are missing. This absence of the subboreal Acanthopleuroceras ancestors suggests the straight celto-souabe derivation of the Portuguese Acanthopleuroceras and not a similar local evolution. A. lepidum the last Acanthopleuroceras reaches the western coast of Canada (British Columbia) probably by the Arctic ocean.

Origin and evolution of Upper Triassic to Miocene clay-mineral associations from the eastern Algarve of Portugal

XRD-analyses of pelitic deposits of Upper Jurassic to Miocene age occuring in the eastern Algarve (Portugal), give evidence of the occurrence of detrital clay minerals of continental origin as well as of conspicuous neoformations of marine provenance. The vertical succession of clay-mineral associations indicates the existence of three distinctive evolutionary cycles which are thought to reflect tectonically controlled transgressive-regressive events.

Performance management in a family business: a case study

This research, still at an early stage, and then presented in a poster format, intended to explain the management of organizational performance of a family business in the succession process using the case study method. The scripts for semi-structured interviews that will apply to managers, owners and other workers who are deemed suitable for the investigation, which include relatives of the owners of the company are being developed. For this work the model of organizational performance management developed by David Otley in 1999 [1], consisting of five questions that seek to explain the existing performance management in any organization is utilized.

Bio and magnetostratigraphy of two Lower Miocene sections, Tagus basin (Portugal)

The magnetostratigraphy of two sections in early Miocene marine deposits of the Tagus Basin is studied. Thermal demagnetization was used to isolate the primary component of magnetization for 45 samples from the Foz da Fonte section, and for 74 others from Trafaria section. The succession of the polarity zones found in these sections is tentatively correlated with the geomagnetic polarity time scale (GPTS) on the basis of the biostratigraphic data yielded by planktic Foraminifera. The planktic zones and magnetic polarities recognized in these sections can be adequately correlated with the part of the GPTS [table calibrated by BERGGRENET al. (1985)] corresponding to the Anomalies 6 and 5E (Foz da Fonte) and 5D (Trafaria). This correlations suggests ages between 19,35 and 18,14 Ma for Foz da Fonte section, and 17,90 to 16,98 Ma for Trafaria.

Late Quaternary warm marine mollusks from Santa Maria (Azores); paleoecologic and paleobiogeographic considerations

The sub-fossil fauna from the Late Quaternary marine deposits of Santa Maria is made of more than 50 species of gastropods and bivalves, 19 of them collected recently and for the first time in the northern coast of the island (Lagoinhas Bay). The sub-fossil shells are found in deposits of beach sands, situated 2-3 meters above the present low tide. The carbonated sands from the basal part of the succession yield an autochthonous association of borers dominated by the bivalve Myoforceps aristata (Dillwin, 1817). Upwards, the marine sands contain concentrations of beach drift shells, including well-preserved supratidal and intertidal gastropods, among them a large number of Rissoidae. The bivalve fauna is dominated by disarticulated valves of Ervilia castanea (Montagu, 1803), a small infaunal coloniser of mobile sandy substrates. The composition of the fauna is made essentially of West European species, many of them common to the West Coast of Portugal. However, a few "warm guests" with West African or Caribbean affinities were also found, suggesting a close relation with some of the "Tyrrhenian" warm associations found in the Western Mediterranean.

The Cenomanian-Turonian transition in West Central Portugal: ammonites and biostratigraphy

The Upper Cenomanian and Lower Turonian ammonite assemblages from the onshore sectors of the West Portuguese Margin are reviewed after new studies on the type section of Figueira da Foz, and correlative sections of Baixo Mondego. The faunal succession shows a strong contribution of vascoceratids and other ammonites with North African and Tethyan affinities. Euomphaloceras septemseriatum (Cragin, 1893), Kamerunoceras douvillei (Pervinquere, 1907), Fagesia catinus (Mantell, 1822), Neoptychites cephalotus (Courtiller, 1860), and Thomasites rollandi (Thomas & Peron, 1889) are for the first time mentioned to Portugal. The Upper Cenomanian is recognised after a set of 3 assemblage zones: Neolobites vibrayeanus z., Euomphaloceras septemseriatum z ., and Pseudaspidoceras pseudonodosoides z. The carbonate succession shows an important unconformity across the Cenomanian-Turonian boundary, associated to subaerial exposure, and to the development of a palaeokarst over Upper Cenomanian units. The first Lower Turonian carbonates are yielded a single but diverse ammonite assemblage of middle Lower Turonian age (Thomasites rollandi z.). This biozone was previously recognised in Central Tunisia by G. Chancellor et al. (1994).
