<p>Holothuria atra or lollyfish is the most common sea cucumber in the Pacific and Indian Oceans. The current status of Holothria atra at 13 sites of South Tarawa lagoon (Republic of Kiribati) was established by using biological surveys and fishers' questionnaires. A preliminary investigation was conducted in order to assess how and why environmental variability and fishing pressure have affected the spatial and temporal distribution, mean abundant and mean size of this species at the sites. The 13 sites were selected randomly, and marked with a GPS on the map of South Tarawa. Sedimentary characteristics were determined for each site, and a qualitative assessment of sites health was made. Lollyfish length, biomass and abundance and transect density were calculated for each site. The weight of organic matter content and size of sediment sample were determined. Data were analysed using Kruskal-Walis (KW) and Repeated measures (RM) ANOVA tests. This thesis shows that the environmental variability could not offer reasons as to why the biological data of lollyfish varied from one site to another. However, other factors that were tested may explain the variation in biological data. Fishing pressure is one of those parameters that can regulate the lollyfish distribution and density and responses from local fishers indicate that fishing pressure is high and that the lollyfish resource is under considerable harvest pressure. Dissolved oxygen concentration in the water column and in the sediment may be also involved in the variation in lollyfish distribution and density but this was not tested. The findings of this research lead to a number of recommendations for the sustainable harvest of lollyfish in Tarawa lagoon. These include consideration of gear restrictions, lollyfish size and number limits, and the establishment of marine protected areas under co-management arrangements.</p>

Abstract Objectives Research have identified large individual variation in physiological response to diet, which has led to more focused investigations in precision nutrition. One approach towards personalized nutrition is to identify groups of differential responders, so called metabotypes (i.e., clusters of individuals with similar metabolic profiles and/or regulation). Metabotyping has previously been addressed using matrix decomposition tools like principal component analysis (PCA) on data organized in matrix form. However, metabotyping using data from more complex experimental designs, involving e.g., repeated measures over time or multiple treatments (tensor data), requires new methods. Methods We developed a workflow for detecting metabotypes from experimental tensor data. The workflow is based on tensor decomposition, specifically PARAFAC which is conceptually similar to PCA but extended to multidimensional data. Metabotypes, based on metabolomics data were identified from PARAFAC scores using k-means clustering and validated by their association to anthropometric and clinical baseline data. Additionally, we evaluated the robustness of the metabotypes using bootstrapping. Furthermore, we applied the workflow to identify metabotypes using data from a crossover acute post-prandial dietary intervention study on 17 overweight males (BMI 25–30 kg/m2, 41–67 y of age) undergoing three dietary interventions (pickled herring, baked herring and baked beef), measuring 80 metabolites (from GC-MS metabolomics) at 8 time points (0–7h). Results  We identified two metabotypes characterized by differences in amino acid levels, predominantly in the beef diet, that were also associated with creatinine (p = 0.007). The metabotype with higher postprandial amino acid levels was also associated with higher fasting creatinine compared to the other metabotype. Conclusions The results stress the potential of PARAFAC to discover metabotypes from complex study designs. The workflow is not restricted to our data structure and can be applied to any type of tensor data. However, PARAFAC is sensitive to data pre-processing and further studies where differential metabotypes are related to clinical endpoints are highly warranted.

Plant breeding has a long history of developing new varieties that have ensured the food security of the human population. During this long journey together with humanity, plant breeders have successfully integrated the latest innovations in science and technologies to accelerate the increase in crop production and quality. For the past two decades, since the completion of human genome sequencing, genomic tools and sequencing technologies have advanced remarkably, and adopting these innovations has enabled us to cost down and/or speed up the plant breeding process. Currently, with the growing mass of genomic data and digitalized biological data, interdisciplinary approaches using new technologies could lead to a new paradigm of plant breeding. In this review, we summarize the overall history and advances of plant breeding, which have been aided by plant genomic research. We highlight the key advances in the field of plant genomics that have impacted plant breeding over the past decades and introduce the current status of innovative approaches such as genomic selection, which could overcome limitations of conventional breeding and enhance the rate of genetic gain.

Thermal Infrared Anomalies

In Hong Kong, there is great abundancy of aged buildings and infrastructures for which a re-assessment of the current status is needed. Water exfiltrations/infiltrations, deteriorating insulations, thermal bridges and regions of failure are among the most recurrent symptoms to be found in existing Reinforced Concrete (RC) structures. Diagnosis of such symptoms, in the form of thermal infrared anomalies, is usually performed through infrared (IR) image capturing, followed by qualitative assessment. This paper presents a novel automated computer-vision-based method for detecting thermal anomalies. Such Computer-Vision (CV) algorithm is tested on different thermal scenarios including beam elements, roofs and entire façades of RC buildings. Thermal anomalies related to cases of water leakages, moisture trapping and debonding are successfully detected. The authors intend to undertake further research for successfully implementing the method for detecting also other thermal dissimilarities.

The presence of an intellectual disability may cause a child to have significant deficits in social skills and emotion regulation abilities across development. A vital next step is to find interventions that can be delivered in the school environment and across disability categories that target socioemotional factors. The current study investigated the feasibility of delivering a school-based musical theater program to students with intellectual disability across a range of school settings. A within-group repeated-measures design was used to analyze pre- and post-video recordings of the intervention program, which were coded for six domains of socioemotional ability across all participants ( n = 47). Results showed that significant gains across all domains were observed. However, these gains related to school- and individual-level student factors, such as grade level, severity of disability, and baseline social skill ability.

In the current information society, the need for securing human resources acquired with ICT competency is becoming a significant factor. Information Communication Technology (ICT) competency describes more than awareness or driving license level of using computing facilities and networking services to carry out different tasks. Undergraduates of a university will become knowledge workers in the society and they should acquire the knowledge, skills and attitudes using the modern ICT technology to carry out their job tasks effectively. This paper presents the current status of ICT Competency in Sri Lankan Universities with respect to both the knowledge and skill requirements of knowledge workers in the job market. However, there are several obstacles are affecting this development and the paper discuss the qualitative assessment of these obstacles in detail. In this study, we propose a new framework for enhancing the ICT Competency among a large number of undergraduates in the University system. This framework consists of two main components namely Infrastructure Development and Virtual Learning Environment. In the component, Infrastructure Development new facilities are provided such as computers, networks and Internet facilities, human resource management and other support services in order to solve the problems identified. Under the Virtual Learning Environment, we propose three levels for undergraduates to address the curriculums of ICT competency. The first two levels are declared with respect to the common ICT Competency Certification and level 3 is declared considering special requirements of curriculum or subject streams.

This short communication addresses the problem associated with the current taxonomic status of the prehistoric edentate genus Neocnus Arredondo, 1961 (with type species Micronocnus gliriformis Matthew, 1931) which has long been considered a senior homonym of the dendrochirotid sea cucumber genus Neocnus Cherbonnier, 1972 (type species Neocnus incubans Cherbonnier, 1972) and replaces the latter (junior homonym) with Incubocnus n.g. The diagnosis of the new genus is the same as the cucumariid Neocnus as amended by O’Loughlin & O’Hara (1992). A brief history of the senior homonym Neocnus (Edentata) is given followed by a short literature survey dealing with its junior homonym.

The article analyzes the international current state of the concept of digital evidence, its meaning, types and role in the process of proving in criminal cases in the practical activities of the preliminary investigation bodies of the Russian Federation, considers some problems arising in law enforcement practice, suggests the author's classification of modern digital traces, studies and compares international practice governing the practical application of digital evidence, their concept and content. The problem of gaps in the legal regulation of digital evidence is considered, as well as the possibility of introducing amendments to the current legislation concerning the legal recognition of digital evidence along with traditional types of evidence, as well as the regulation of the use of digital evidence in criminal proceedings, and a proposal is made to introduce a number of amendments to the current legislation of the Russian Federation, where it is necessary to secure definitions of digital evidence, thus legalizing it, stating in the following re At the same time, it is noted that there is no need to introduce a separate article to regulate digital (electronic) evidences, because it is rather difficult to determine the volume of digital (electronic) evidences (digital criminally significant information), at least because there is no unanimity in this respect and there was no unanimity, besides, due to the dynamic development of electronics, including personal ones, this norm quickly lost its relevance and required amendments, creating a certain gap in legal regulation, which is more complicated.
