Transformation of Platymonas (Tetraselmis) subcordiformis (Prasinophyceae, Chlorophyta) by agitation with glass beads

A transient transformation system for the unicellular marine green alga, Platymonas subcordiformis, was established in this study. We introduced the pEGFP-N1 vector into P. subcordiformis with a glass bead method. P. subcordiformis was incubated in cell wall lytic enzymes (abalone acetone powder and cellulase solutions) to degrade the cell wall. The applicable conditions for production of viable protoplasts were pH 6.5, 25 degrees C, and 3 h of enzyme treatment. The protoplast yield was 61.2% when P. subcordiformis cells were added to the enzyme solution at a concentration of 10(7) cell ml(-1). The protoplasts were immediately transformed with the pEGFP-N1 vector using glass-bead method. The transformation frequency was about 10(-5), and there was no GFP activity observed in either the negative or the blank controls. This study indicated that GFP was a sensitively transgenic reporter for P. subcordiformis, and the method of cell wall enzymolysis followed by glass bead agitation was applicable for the transformation of P. subcordiformis.

Observations on the nocturnal activity and feeding behavior of Anguilla japonica glass eels under laboratory conditions

Glass eels of the temperate anguillid species, Anguilla japonica, clearly showed a nocturnal activity rhythm under laboratory conditions. Light-dark cycle was a determinant factor affecting their photonegative behavior, nocturnal locomotor activity, and feeding behavior. Under natural light conditions, glass eels remained in shelters with little daytime feeding, but came out to forage during darkness. They moved and foraged actively in the following dark, and then their activity gradually declined possibly because of food satiation. They finally buried in the sand or stayed in tubes immediately after the lights came on. Under constant light, glass eels often came out of the shelters to forage in the lights but spent little time moving outside the shelters (e.g. swimming or crawling on the sand). Glass eels took shelter to avoid light and preferred tubes to sand for shelter possibly because tubes were much easier for them to take refuge in than sand. Feeding and locomotor activities of the glass eels were nocturnal and well synchronized. They appeared to depend on olfaction rather than vision to detect and capture prey in darkness. Feeding was the driving force for glass eels to come out of sand under constant light. However, in the dark, some glass eels swam or crept actively on sand even when they were fully fed. The lunar cycles of activity rhythms of glass eels that have been observed in some estuarine areas were not detected under these laboratory conditions.

Islamic corporate financing : does it promote profit and loss sharing?

Islamic financing instruments can be categorised into profit and loss/risk sharing and non-participatory instruments. Although profit and loss sharing instruments such as musharakah are widely accepted as the ideal form of Islamic financing, prior studies suggest that alternative instruments such as murabahah are preferred by Islamic banks. Nevertheless, prior studies did not explore factors that influence the use of Islamic financing among non-financial firms. Our study fills this gap and contributes new knowledge in several ways. First, we find no evidence of widespread use of Islamic financing instruments across non-financial firms. This is because the instruments are mostly used by less profitable firms with higher leverage (i.e., risky firms). Second, we find that profit and loss sharing instruments are hardly used, whilst the use of murabahah is dominant. Consistent with the prediction of moral-hazard-risk avoidance theory, further analysis suggests that users with a lower asset base (to serve as collateral) are associated with murabahah financing. Third, we present a critical discourse on the contentious nature of murabahah as practised. The economic significance and ethical issues associated with murabahah as practised should trigger serious efforts to steer Islamic corporate financing towards risk-sharing more than the controversial rent-seeking practice.

Impact of Islamic values on HRM practices: an empirical study of Jordanian universities

Purpose This study aims to present an in-depth theoretical and practical analysis of HRM practice in the light of Islamic values and principles. It looks at the four main HRM functions of recruitment and selection, training and development, performance appraisal, and rewards, from the Islamic perspective. Besides establishing a theoretical base for the influence of Islam on HRM, it analyses the key characteristics of HRM practice as applied in Jordanian universities and analyses the extent to which Islamic values are embedded in that practice. Design/methodology/approach The paper draws on a structured questionnaire distributed to 500 respondents working in four Jordanian universities which sought to elicit the respondents views on the influence of Islamic values within specific HR functions. Findings The findings indicate that there is a diffusion of Islamic values into HRM practice in the participating organisations. The extent of the diffusion varies between the organisations; there is a clear indication that explicitly Islamic values are being practiced, albeit to a limited extent. Originality/value The role of spirituality and/or religion in shaping the working of contemporary organisations is not sufficiently recognised in the literature. This paper is a response to the limited number of research studies assessing the extent of the absorption of religious values into the management of human resources. The study undertaken examines the current status of HRM practice in Jordanian universities and contributes to deepening the contemporary understanding of interactions between Islamic values and the core HR functions.

The Viking age glass beads of Ireland and their North Atlantic context

Hitherto, the majority of studies which have included the discussion of Viking glass beads have mainly focused on the assemblages from individual sites, with limited use of known parallels. Exceptions to this include recent publications regarding the Icelandic material and Callmer’s 1977 catalogue of the finds from mainland Scandinavia, now over thirty years old. Analysis of these finds from Ireland was, for the most part, non-existent. The aim of this research is to address this lack of analysis within Ireland, while incorporating the wider context of the beads within the Viking North Atlantic. The research thus examines the use of glass beads of diagnostically Scandinavian manufacture and import found in Ireland, particularly in relation to their context and distribution. The history of research from Ireland as well as from across the Viking world is considered and explored throughout the thesis, with critique of methods and discussions used. Focussed analysis of both published and unpublished material detailing artefacts from Scandinavia (especially Vestfold), Britain, Iceland, the Faroe Islands and L’Anse aux Meadows is presented within the thesis in order to provide the greater picture for the core section of the thesis, the glass beads found in Ireland. Three appendices are included within Volume 2, databases of the glass beads under discussion from Ireland, the Vestfold region graves in Norway and the topsoil finds from the Kaupang trading place, also located within Vestfold. These appendices therefore represent the first-hand analysis of glass beads by the author. In total, this research represents the most up-to-date analysis of Viking glass beads from Ireland and presents a new look at the patterns of use, trade and interpersonal contact that affected the everyday lives of individuals living within Viking Age Ireland.

The Islamic commercial crisis: Institutional roots of economic underdevelopment in the Middle East

During the second millennium, the Middle East's commerce with Western Europe fell increasingly under European domination. Two factors played critical roles. First, the Islamic inheritance system, by raising the costs of dissolving a partnership following a partner's death, kept Middle Eastern commercial enterprises small and ephemeral. Second, certain European inheritance systems facilitated large and durable partnerships by reducing the likelihood of premature dissolution. The upshot is that European enterprises grew larger than those of the Islamic world. Moreover, while ever larger enterprises propelled further organizational transformations in Europe, persistently small enterprises inhibited economic modernization in the Middle East.
