AbstractPrevious studies suggest that tropical storms and hurricanes are among the leading causes of shipwrecks in the Caribbean Sea since 1492. This paper will explore the relationship between shipwrecks and hurricanes in the Western Caribbean, particularly Roncador Cay, a place with complex environmental conditions that have made this area a trap for ships, but has up until now, been without rigorous shipwreck analysis. This study covers the period 1492 to 1920 with search results of 23 shipwrecks and 37 tropical cyclones compiled in databases, reviewing seven wrecks already documented and revealing new information on 16, previously not recorded. The sources provide detailed shipwrecks, demonstrating that most accidents occurred by unspecific causes and no direct relationship with hurricanes but were influenced by environmental conditions, such as geomorphology, cold fronts, or currents. There is also a reflection on the sociocultural changes and the influence of power in the region. The study includes a suggested tool for future research, protecting the wreck site and emphasizing the importance of the underwater cultural heritage as an indicator of the active maritime past.

In waters of the Northwestern Atlantic pelagic tunicates may contribute significantly to the plankton biomass; however, theregional information on the salp fauna is scarce and limited to restricted sectors. In the Caribbean Sea (CS) and the Gulf ofMexico (GOM) the composition of the salpid fauna is still poorly known and this group remains among the less studiedzooplankton taxa in the Northwestern Tropical Atlantic. A revised checklist of the salp species recorded in the North At-lantic (NA, 0–40° N) is provided herein, including new information from the Western Caribbean. Zooplankton sampleswere collected during two cruises (March 2006, January 2007) within a depth range of 0–941 m. A total of 14 species wererecorded in our samples, including new records for the CS and GOM area (Cyclosalpa bakeri Ritter 1905), for the CS (Cy-closalpa affinis (Chamisso, 1819)), and for the Western Caribbean (Salpa maxima Forskål, 1774). The number of speciesof salps known from the CS and GOM rose to 18. A key for the identification of the species recorded in the region is provided. Studies on the ecological role of salps in several sectors of the NA are scarce and deserve further attention.

The windward reef complex NE and E of San Andrés Island is briefly described in terms of submarine topography, sediments and the distribution of corals and other benthonic organisms. The breaker zone of the San Andrés barrier and other exposed Western Caribbean reefs characteristically exhibits a profuse growth consisting almost exclusively of Millepora. In this respect they are different from most other described West Indian reef localities, where Acropora palmata is the dominating species in this part of the reef. The replacement of Acropora palmata by Millepora is interpreted as an adaptation of the reef crest community to high energy environments due to long swell prevailing at the Western end of the Caribbean Sea. A few short reef sections exposed to the maximum degree of wave energy show conspicuous algal ridges.

Siphonophores are one of the least known gelatinous zooplankters in the tropical waters of the Northwestern Atlantic. Most of the regional knowledge about their diversity and distribution is based on surface samples (0–200 m). Siphonophores were collected from oceanic waters off the Mexican Caribbean across an expanded sampling range (0–940 m) during two cruises and were taxonomically examined. A total of 47 siphonophore species were recorded, of these, 14 had not been found in this sector of the Caribbean Sea and 10 represent new records for the Caribbean Basin. The number of species currently known from the western Caribbean is increased from 42 to 56. Some of these species also represent new records for the Northwestern Tropical Atlantic region. The greatest relative increase was observed among species of Lensia, five of which are exclusively deep-living forms dwelling below 300 m. A revised, expanded checklist of the siphonophores of the Western Caribbean is also provided. These results confirm the need of further deep sampling to increase our understanding of Caribbean siphonophore diversity.

This study examines the nature of the relationship between journalists and politicians in the age of media entrepreneurship, with emphasis on the factors and challenges faced by both media entrepreneurs and politicians while using digital media. This study relies on an inductive approach through using the qualitative method, this involves conducting interviews (N: 41) with journalists to discover whether they work in traditional media organizations or/and own and manage digital media enterprises, it also brings to lights new information about politicians, especially those who have media inclinations. This study reveals that digital media provide journalists with opportunities to achieve professional and financial independence. However, their work in the context of Iraqi scope does not go beyond spreading propaganda and promoting various agenda of political parties and politicians. In terms of the content of media entrepreneurship, this study unveils anonymous social media which are affiliated with/ or supported by politicians which work as piracy for trolling political opponents and activists. It is assumed that such social media have serious repercussions for freedom and privacy. This worries activists and journalists that they are unable to express their opinions freely for fear of being attacked by anonymous social media working on behalf of politicians. Therefore, the ethics of social media and their ownership seems to be a major concern in the Iraqi political media space, and it should be taken into consideration in future research.

Co-creation is a special type of collaboration that co-opts individuals in an innovative way for creating value. Engaging in co-creation can result in mutual benefit for the participants as they obtain favourable end results or exchange knowledge and skills but may be challenging when an individual may not be ready or willing to co-create. This makes it imperative that an individual's readiness to co-create (RTCC) is understood and factored into the management of co-creative processes. Drawing from research on readiness to collaborate, factors that determine RTCC are examined in this article. Specifically, the relationship between constructs of individual value system (IVS), organisational value system (OVS), contextual-environmental conditions (EC), intrapersonal characteristics (IntraCharac), interpersonal characteristics (InterCharac), and RTCC are examined. Post confirmatory factor analysis indicated that most of the variables of the six constructs had loaded on a particular factor except for IntraCharac that loaded only 2 variables. Based on these results, multiple regressions were performed, which indicated that environmental conditions and InterCharac did have significant influence on RTCC whereas IntraCharac did not have a strong effect. Managerial implications and potential future research directions are also highlighted.

In the framework of a research on taxonomy and ecology of selected families of polychaetes conducted at the field station of the Smithsonian Institution (Washington DC, USA) at Carrie Bow Cay (Belize, Western Caribbean Sea) on November 2005, several qualitative benthic samples from different habitats and substrate types (Thalassia testudinum shoots, fragments of dead hard corals, sponges) have been analyzed. In some of these samples, specimens of Sabellidae were found, revealing, together with some taxa already known for the area, the presence of two new species, Megalomma fauchaldi sp. nov., and Pseudoaugeneriella spongicola sp. nov., this latter representing a genus newly reported from the Caribbean. Sabellidae biodiversity and systematics between Caribbean and Mediterranean regions is also compared.

Abstract. Background: Previous research has demonstrated an association between alcohol-related problems and suicidal ideation (SI). Aims: The present study evaluated, simultaneously, alcohol consequences and symptoms of alcohol dependence as predictors of SI after adjusting for depressive symptoms and alcohol consumption. Method: A sample of 298 Alaskan undergraduates completed survey measures, including the Young Adult Alcohol Consequences Questionnaire, the Short Alcohol Dependence Data Questionnaire, and the Beck Depression Inventory – II. The association between alcohol problems and SI status was evaluated using sequential logistic regression. Results: Symptoms of alcohol dependence (OR = 1.88, p < .05), but not alcohol-related consequences (OR = 1.01, p = .95), emerged as an independent predictor of SI status above and beyond depressive symptoms (OR = 2.39, p < .001) and alcohol consumption (OR = 1.08, p = .39). Conclusion: Alcohol dependence symptoms represented a unique risk for SI relative to alcohol-related consequences and alcohol consumption. Future research should examine the causal mechanism behind the relationship between alcohol dependence and suicidality among university students. Assessing the presence of dependence symptoms may improve the accuracy of identifying students at risk of SI.

The Relationship

Abstract. Recently, Garfinkel and Critchley (2013) proposed to distinguish between three facets of interoception: interoceptive sensibility, interoceptive accuracy, and interoceptive awareness. This pilot study investigated how these facets interrelate to each other and whether interoceptive awareness is related to the metacognitive awareness of memory performance. A sample of 24 healthy students completed a heartbeat perception task (HPT) and a memory task. Judgments of confidence were requested for each task. Participants filled in questionnaires assessing interoceptive sensibility, depression, anxiety, and socio-demographic characteristics. The three facets of interoception were found to be uncorrelated and interoceptive awareness was not related to metacognitive awareness of memory performance. Whereas memory performance was significantly related to metamemory awareness, interoceptive accuracy (HPT) and interoceptive awareness were not correlated. Results suggest that future research on interoception should assess all facets of interoception in order to capture the multifaceted quality of the construct.
