16S rRNA sequencing reveals likely beneficial core microbes within faecal samples of the EU protected slug Geomalacus maculosus

The EU-protected slug Geomalacus maculosus Allman occurs only in the West of Ireland and in northern Spain and Portugal. We explored the microbial community found within the faeces of Irish specimens with a view to determining whether a core microbiome existed among geographically isolated slugs which could give insight into the adaptations of G. maculosus to the available food resources within its habitat. Faecal samples of 30 wild specimens were collected throughout its Irish range and the V3 region of the bacterial 16S rRNA gene was sequenced using Illumina MiSeq. To investigate the influence of diet on the microbial composition, faecal samples were taken and sequenced from six laboratory reared slugs which were raised on two different foods. We found a widely diverse microbiome dominated by Enterobacteriales with three core OTUs shared between all specimens. While the reared specimens appeared clearly separated by diet in NMDS plots, no significant difference between the slugs fed on the two different diets was found. Our results indicate that while the majority of the faecal microbiome of G. maculosus is probably dependent on the microhabitat of the individual slugs, parts of it are likely selected for by the host

The Icelandic Prevention Model Evaluation Framework and Implementation Integrity and Consistency Assessment

The Icelandic Prevention Model (IPM) follows a systematic but flexible process of community capacity building, data collection, analysis, dissemination, and community-engaged decision-making to guide the data-informed selection, prioritization, and implementation of intervention strategies in preventing adolescent substance use. This paper describes two new evaluation tools intended to assess the: 1) integrity of IPM implementation, and 2) unique aspects of IPM implementation in different community contexts. These evaluation tools include a: 1) five-phase IPM Evaluation Framework for Assessing Value Across Communities, Cultures, and Outcomes (IPM-EF); and 2) 10-Step IPM Implementation Integrity and Consistency Assessment (IPM-IICA) that utilizes both quantitative (scored) and qualitative (narrative) data elements to characterize implementation integrity and consistency at both community coalition and school community levels. The IPM-EF includes five phases. Phase 1: Describe the Intervention Context; Phase 2a: Document the Extent to Which the 10 Steps of the IPM were Implemented (using the IPM-IICA scored); Phase 2b: Document the Unique Community-Specific Methods Used within the 10 Steps of the IPM to Tailor Local Intervention Delivery (using the IPM-IICA narrative); Phase 3: Measure Changes in Community Risk and Protective Factors; Phase 4: Measure the Outcomes Associated with the IPM; and Phase 5: Investigate Multiple Full Cycles Over Time

The flow of the Antarctic circumpolar current over the North Scotia Ridge

The transports associated with the Subantarctic Front (SAF) and the Polar Front (PF) account for the majority of the volume transport of the Antarctic Circumpolar Current (ACC). After passing through Drake Passage, the SAF and the PF veer northward over the steep topography of the North Scotia Ridge. Interaction of the ACC with the North Scotia Ridge influences the sources of the Malvinas Current. This ridge is a major obstacle to the flow of deep water, with the majority of the deep water passing through the 3100 m deep gap in the ridge known as Shag Rocks Passage. Volume transports associated with these fronts were measured during the North Scotia Ridge Overflow Project, which included the first extensive hydrographic survey of the ridge, carried out in April and May 2003. The total net volume transport northward over the ridge was found to be . The total net transport associated with the SAF was approximately , and the total transport associated with the PF was approximately . Weddell Sea Deep Water was not detected passing through Shag Rocks Passage, contrary to some previous inferences

Clima organizacional de los colaboradores de la línea de máquinas semiautomáticas de una empresa productora de bebidas, en Huachipa – Perú en el 2020

El presente trabajo de investigación tiene como título “Clima organizacional de los colaboradores de la línea de máquinas semiautomáticas de una empresa productora de bebidas, en Huachipa – Perú en el 2020” como objetivo general se propuso determinar la tendencia del clima organizacional de los colaboradores de la línea de máquinas semiautomáticas de una empresa productora de bebidas, en Huachipa – Perú en el 2020. Referente a la metodología aplicada, se tuvo un enfoque cuantitativo descriptivo; para la recolección de datos, se aplicó un cuestionario de clima organizacional validado por Litwin y Stringer, constituido por 5 dimensiones y 31 ítems, lo cual fueron relacionados directamente al análisis de la variable de estudio, siendo aplicado a 28 colaboradores de una misma área de trabajo. Los resultados concluyeron que el clima organizacional tiene una tendencia favorable con un porcentaje mayor al 78%, sin embargo, existen dimensiones por trabajar como recompensa, relaciones e identidad que se podrían trabajar para fomentar un mejor clima organizacional, buscando maximizar la productividad de los trabajadores que integren el área.The present research work is entitled "Organizational climate of the collaborators of the line of semi-automatic machines of a beverage producing company, in Huachipa - Peru in 2020" as a general objective it was proposed to determine the level of the organizational climate of the collaborators of the line of semiautomatic machines of a beverage producing company, in Huachipa - Peru in 2020. Regarding the applied methodology, a descriptive quantitative approach was used; For data collection, an organizational climate questionnaire validated by Litwin and Stringer was applied, consisting of 5 dimensions and 31 items, which were directly related to the analysis of the study variable, being applied to 28 collaborators from the same area of job.

Platelet ice, the Southern Ocean’s hidden ice: a review

Basal melt of ice shelves is not only an important part of Antarctica’s ice-sheet mass budget, but it is also the origin of one of the most peculiar types of sea ice found in the polar oceans: platelet ice. In many regions around coastal Antarctica, tiny ice crystals form and grow in supercooled plumes of Ice Shelf Water, releasing heat into the surrounding ocean. They usually rise towards the surface, eventually becoming trapped under an ice shelf as marine ice. Frequently, masses of those crystals are advected out of the ice-shelf cavity, and accumulate below a solid sea-ice cover to form a semiconsolidated layer. When the overlying sea ice grows into this so-called sub-ice platelet layer, the loose crystals are consolidated, adding additional thickness to the sea ice. These phenomena are generally referred to as platelet ice, although confusion about the terminology is widespread in the literature. The presence of platelet ice has a profound impact on sea-ice properties and processes in several regions of Antarctica, with numerous implications for the local polar marine biosphere. Most notably, sub-ice platelet layers provide a stable, sheltered, nutrient- and food-rich habitat which usually results in a highly productive and uniquely adapted ecosystem. It has also been hypothesised that platelet ice may be an indicator of the state of an ice shelf, although comprehensive time series are limited to the Ross Sea. This paper clears up the terminology by providing exact definitions of the relevant terms.We review platelet-ice formation, observational methods as well as geographical and seasonal occurrence. The physical properties and ecological implications are merged in a way understandable for physicists and biologists alike, to lay the foundation for the interdisciplinary research that is necessary to tackle the current knowledge gaps

Consistency and communication in committees

We generalize the classical binary Condorcet jury model by introducing a richer state and signal space, thereby generating a concern for consistency in the evaluation of aggregate information. We analyze truth-telling incentives in simultaneous pre-vote communication in heterogeneous committees and find that full pooling of information followed by sincere voting is compatible with a positive probability of ex post conflict in the committee
