A salt-marsh assemblage of agglutinated foraminifera was recovered from a salt marsh on the east side of Tubli Bay in eastern Bahrain. This locality is one of the last remaining patches of salt marsh on the east coast of Tubli Bay. The salt marsh is covered by a single marsh plant species, Arthrocnemum macrostachyum. Samples were collected from beneath the Arthrocnemum canopy in two transects beginning at the maximum landward extent of halophytic plants in the high marsh and extending to a tidal channel at the seaward side of the low marsh. A distinct elevation-related zonation in foraminifera is observed from the high marsh to the low marsh. The trochamminids Entzia macrescens and Trochammina inflata are characteristic of the high marsh, whereas Ammonia, Elphidium, Peneroplis and smaller miliolids become common in the middle part of the marsh transect. The tidal channel at the lower limit of the marsh contains an assemblage dominated by Ammonia, Elphidium, adult specimens of Peneroplis, and smaller miliolids, with Clavulina and Agglutinella as the only agglutinated taxa. Living specimens of Entzia and Trochammina were observed during the winter 2019–2020 sampling season, whereas samples collected in Autumn 2019 contained only dead specimens. One new species, ?Sigmoilina canisdementis sp. nov., is described herein. This is the first report of a live Entzia-dominated salt marsh assemblage in the Arabian Gulf region.

The aim of this paper is to explore the relationship between corporate governance and performance of the financial firms in the Kingdom of Bahrain. The study uses annual data of all listed financial firms on the Bahrain Bourse over the period of 2011-2016. The results show that board size, ownership concentration and auditor’s reputation have a positive and significant impact on firms’ return on assets (ROA), whereas the percentage of independent directors and the annual number of board meetings have negative and significant impact on firms’ return on equity (ROE). CEO duality is found to not be an important determinant factor of firms’ performance, as the results suggest that it shows insignificant effect on ROA, ROE and stock returns (SPR). Furthermore, firm’s size and leverage are found to have negative and insignificant relationship with firms’ performance.

Celem artykułu jest zbadanie związku między ładem korporacyjnym a wynikami firm finansowych w Królestwie Bahrajnu. W badaniu wykorzystano roczne dane wszystkich notowanych firm finansowych w Bahrajnie w okresie 2011-2016. Wyniki pokazują, że wielkość zarządu, koncentracja własności i reputacja audytora mają pozytywny i znaczący wpływ na rentowność aktywów przedsiębiorstw (ROA), podczas gdy odsetek niezależnych dyrektorów i roczna liczba posiedzeń zarządu mają negatywny i znaczący wpływ na przedsiębiorstwa z kapitałem własnym (ROE). Dualizm dyrektorów generalnych nie jest istotnym czynnikiem determinującym wydajność firm, ponieważ wyniki sugerują, że ma on niewielki wpływ na ROA, ROE i stopy zwrotu (SPR). Ponadto stwierdzono, że wielkość firmy i jej wpływ mają negatywny i nieistotny związek z jej wydajnością.

The various facets and networks of social media have had significantly phenomenal influence on the individual life and on the societal, economic, and political status of their users. The linguistic discourse of interlocutors on social media has also been influenced. The current study aims at measuring how the English language learning process of non-native Bahrainis has been affected by the use of social media. To explore such effects, a quantitative methodological measure was used in the form of an online questionnaire administered to a random sample of L2 Bahrainis. Responses from 330 respondents from different age groups and gender types were analysed using measures of central tendency and other statistical measures such as t-tests and ANOVA using SPSS. Findings have revealed that the utilization of social media has been perceived to have positively impacted interlocutors’ lexical variation, writing style, reading skills, and communication skills. These findings were subjective to variables related to gender, age, and the multimodality of particular social media facets. Accordingly, some significant implications and recommendations are drawn, the most important of which is the provision of mechanisms to ensure the effective utilisation and employment of social media in the pedagogical practices in L2 contexts.
