Population genetic structure of brown crab (Cancer pagurus) in Irish waters

The brown crab (Cancer pagurus) fishery in Ireland is one of the most important financially and socio-economically, with the species worth approximately €15m per year in the first half of the decade. Only mackerel (Scomber scombrus) and Dublin Bay prawn (Nephrops norvegicus) are of greater value. Despite this, very little research has been conducted to describe the stock structure of brown crab on a national scale. In this study a country-wide assessment of genetic population structure was carried out. Sampling was conducted from commercial fishing boats from 11/06 to 04/08 at seven sample sites representing the central Irish brown crab fisheries, with one sample site from the UK also included in the study. Six microsatellite markers, specifically developed for brown crab, were used to assess genetic diversity and estimate population differentiation parameters. Significant genetic structuring was found using F-statistics (Fst = 0.007) and exact tests, but not with Bayesian methods. Samples from the UK and Wexford were found to be genetically distinct from all other populations. Three northern populations from Malm Head and Stanton Bank were genetically similar with Fst estimates suggesting connectivity between them. Also, Stanton Bank, again on the basis of Fst estimates, appeared to be connected to populations down the west coast of Ireland, as far south as Kerry. Two Galway samples, one inside and one outside of Galway Bay, were genetically differentiated despite their close geographic proximity. It is hypothesised that a persistent northerly summer current could transport pelagic larvae from populations along the southwest and west coasts of Ireland towards Stanton Bank in the North, resulting in the apparent connectivity observed in this study.

A study of the interaction between national and corporate culture in a selection of Irish based companies

This research studies the phenomenon of national and corporate culture. National culture is the culture the members of a country share and corporate culture is a subculture which members of an organisation share (Schein, 1992). The objective of this research is to reveal if the employees within equivalent Irish and American companies share the same corporate and national culture and to ascertain if, within each company, there is a link between national culture and corporate culture. The object of this study is achieved by replicating research which was conducted by Shing (1997) in Taiwan. Hypotheses and analytical tools developed by Shing are employed in the current study to allow comparison of results between Shing’s study and the current study. The methodology used, called for the measurement and comparison of national and corporate culture in two equivalent companies within the same industry. The two companies involved in this study are both located in Ireland and are of American and Irish origin. A sample of three hundred was selected and the response rate was 54%. The findings from this research are: (1) The two companies involved had different corporate cultures, (2) They had the same national culture, (3) There was no link between national culture and corporate culture within either company, (4) The findings were not similar to those of Shing (1997). The implication of these findings is that national and corporate culture are separate phenomena therefore corporate culture is not a response to national culture. The results of this research are not reflected in the finding’s of Shing (1997), therefore they are context specific. The core recommendation for management is that, corporate culture should take account of national culture. This is because although employees recognise the espoused values of corporate culture (Schein, 1992), they are at the same time influenced by a much stronger force, their national culture.

Frequency of Cardiovascular Involvement in Familial Amyloidotic Polyneuropathy in Brazilian Patients

Background:Familial amyloidotic polyneuropathy (FAP) is a rare disease diagnosed in Brazil and worldwide. The frequency of cardiovascular involvement in Brazilian FAP patients is unknown.Objective:Detect the frequency of cardiovascular involvement and correlate the cardiovascular findings with the modified polyneuropathy disability (PND) score.Methods:In a national reference center, 51 patients were evaluated with clinical examination, electrocardiography (ECG), echocardiography (ECHO), and 24-hour Holter. Patients were classified according to the modified PND score and divided into groups: PND 0, PND I, PND II, and PND > II (which included PND IIIa, IIIb, and IV). We chose the classification tree as the statistical method to analyze the association between findings in cardiac tests with the neurological classification (PND).Results:ECG abnormalities were present in almost 2/3 of the FAP patients, whereas ECHO abnormalities occurred in around 1/3 of them. All patients with abnormal ECHO also had abnormal ECG, but the opposite did not apply. The classification tree identified ECG and ECHO as relevant variables (p < 0.001 and p = 0.08, respectively). The probability of a patient to be allocated to the PND 0 group when having a normal ECG was over 80%. When both ECG and ECHO were abnormal, this probability was null.Conclusions:Brazilian patients with FAP have frequent ECG abnormalities. ECG is an appropriate test to discriminate asymptomatic carriers of the mutation from those who develop the disease, whereas ECHO contributes to this discrimination.
