Linguistic relativity and dialectical idiomatization: language ideologies and second language acquisition in the Irish language revival of Northern Ireland

A considerable number of Irish Catholics in West Belfast, originally native English speakers, have started learning the Irish language throughout the Northern Irish conflict in order to feel more Irish. Many of these have developed a strong conviction that the Irish language contains a different worldview from the one embodied in English. However, rather than constituting a plausible representation of relevant differences embodied in the languages themselves, this article puts forward the hypothesis that such a neo-Whorfian endorsement of linguistic relativity might rather be the product of dialectical idiomatization, following from the interplay of prevailing language ideologies and effects of second language acquisition.

Alveolar bone regeneration in response to local application of calcitriol in vitamin D deficient rats

AIM Vitamin D deficiency is considered to diminish bone regeneration. Yet, raising the serum levels takes months. A topic application of the active vitamin D metabolite, calcitriol, may be an effective approach. Thus, it becomes important to know the effect of vitamin D deficiency and local application on alveolar bone regeneration. MATERIAL AND METHODS Sixty rats were divided into three groups; two vitamin depletion groups and a control group. Identical single defects (2 mm diameter) were created in the maxilla and mandible treated with calcitriol soaked collagen in one deficiency group while in the other two groups not. Histomorphometric analysis and micro CTs were performed after 1 and 3 weeks. Serum levels of 25(OH)D3 and PTH were determined. RESULTS Bone formation rate significantly increased within the observation period in all groups. Bone regeneration was higher in the maxilla than in the mandible. However, bone regeneration was lower in the control group compared to vitamin depletion groups, with no significant effects by local administration of calcitriol (micro CT mandible p = 0.003, maxilla p < 0.001; histomorphometry maxilla p = 0.035, mandible p = 0.18). CONCLUSION Vitamin D deficiency not necessarily impairs bone regeneration in the rat jaw and a single local calcitriol application does not enhance healing.
