    Full Text Available Abstract Background X chromosome inactivation, the mechanism used by mammals to equalise dosage of X-linked genes in XX females relative to XY males, is triggered by chromosome-wide localisation of a cis-acting non-coding RNA, Xist. The mechanism of Xist RNA spreading and Xist-dependent silencing is poorly understood. A large body of evidence indicates that silencing is more efficient on the X chromosome than on autosomes, leading to the idea that the X chromosome has acquired sequences that facilitate propagation of silencing. LINE-1 (L1 repeats are relatively enriched on the X chromosome and have been proposed as candidates for these sequences. To determine the requirements for efficient silencing we have analysed the relationship of chromosome features, including L1 repeats, and the extent of silencing in cell lines carrying inducible Xist transgenes located on one of three different autosomes. Results Our results show that the organisation of the chromosome into large gene-rich and L1-rich domains is a key determinant of silencing efficiency. Specifically genes located in large gene-rich domains with low L1 density are relatively resistant to Xist-mediated silencing whereas genes located in gene-poor domains with high L1 density are silenced more efficiently. These effects are observed shortly after induction of Xist RNA expression, suggesting that chromosomal domain organisation influences establishment rather than long-term maintenance of silencing. The X chromosome and some autosomes have only small gene-rich L1-depleted domains and we suggest that this could confer the capacity for relatively efficient chromosome-wide silencing. Conclusions This study provides insight into the requirements for efficient Xist mediated silencing and specifically identifies organisation of the chromosome into gene-rich L1-depleted and gene-poor L1-dense domains as a major influence on the ability of Xist-mediated silencing to be propagated in a continuous

    Full Text Available Abstract Background Domains are the building blocks of proteins. During evolution, they have been duplicated, fused and recombined, to produce proteins with novel structures and functions. Structural and genome-scale studies have shown that pairs or groups of domains observed together in a protein are almost always found in only one N to C terminal order and are the result of a single recombination event that has been propagated by duplication of the multi-domain unit. Previous studies of domain organisation have used graph theory to represent the co-occurrence of domains within proteins. We build on this approach by adding directionality to the graphs and connecting nodes based on their relative order in the protein. Most of the time, the linear order of domains is conserved. However, using the directed graph representation we have identified non-linear features of domain organization that are over-represented in genomes. Recognising these patterns and unravelling how they have arisen may allow us to understand the functional relationships between domains and understand how the protein repertoire has evolved. Results We identify groups of domains that are not linearly conserved, but instead have been shuffled during evolution so that they occur in multiple different orders. We consider 192 genomes across all three kingdoms of life and use domain and protein annotation to understand their functional significance. To identify these features and assess their statistical significance, we represent the linear order of domains in proteins as a directed graph and apply graph theoretical methods. We describe two higher-order patterns of domain organisation: clusters and bi-directionally associated domain pairs and explore their functional importance and phylogenetic conservation. Conclusion Taking into account the order of domains, we have derived a novel picture of global protein organization. We found that all genomes have a higher than expected

    Chromosomes have a complex architecture in the cell nucleus, which serves vital functional purposes, yet its structure and folding mechanisms remain still incompletely understood. Here we show that genome-wide chromatin architecture data, as mapped by Hi-C methods across mammalian cell types and chromosomes, are well described by classical scaling concepts of polymer physics, from the sub-Mb to chromosomal scales. Chromatin is a complex mixture of different regions, folded in the conformational classes predicted by polymer thermodynamics. The contact matrix of the Sox9 locus, a region linked to severe human congenital diseases, is derived with high accuracy in mESCs and its molecular determinants identified by the theory; Sox9 self-assembles hierarchically in higher-order domains, involving abundant many-body contacts. Our approach is also applied to the Bmp7 locus. Finally, the model predictions on the effects of mutations on folding are tested against available data on a deletion in the Xist locus. Our results can help progressing new diagnostic tools for diseases linked to chromatin misfolding.

    Full Text Available The centromere is a functional chromosome domain that is essential for faithful chromosome segregation during cell division and that can be reliably identified by the presence of the centromere-specific histone H3 variant CenH3. In monocentric chromosomes, the centromere is characterized by a single CenH3-containing region within a morphologically distinct primary constriction. This region usually spans up to a few Mbp composed mainly of centromere-specific satellite DNA common to all chromosomes of a given species. In holocentric chromosomes, there is no primary constriction; the centromere is composed of many CenH3 loci distributed along the entire length of a chromosome. Using correlative fluorescence light microscopy and high-resolution electron microscopy, we show that pea (Pisum sativum chromosomes exhibit remarkably long primary constrictions that contain 3-5 explicit CenH3-containing regions, a novelty in centromere organization. In addition, we estimate that the size of the chromosome segment delimited by two outermost domains varies between 69 Mbp and 107 Mbp, several factors larger than any known centromere length. These domains are almost entirely composed of repetitive DNA sequences belonging to 13 distinct families of satellite DNA and one family of centromeric retrotransposons, all of which are unevenly distributed among pea chromosomes. We present the centromeres of Pisum as novel "meta-polycentric" functional domains. Our results demonstrate that the organization and DNA composition of functional centromere domains can be far more complex than previously thought, do not require single repetitive elements, and do not require single centromere domains in order to segregate properly. Based on these findings, we propose Pisum as a useful model for investigation of centromere architecture and the still poorly understood role of repetitive DNA in centromere evolution, determination, and function.

  9. Transcription rate and transcript length drive formation of chromosomal interaction domain boundaries.

    Le, Tung Bk; Laub, Michael T

    2016-07-15

    Chromosomes in all organisms are highly organized and divided into multiple chromosomal interaction domains, or topological domains. Regions of active, high transcription help establish and maintain domain boundaries, but precisely how this occurs remains unclear. Here, using fluorescence microscopy and chromosome conformation capture in conjunction with deep sequencing (Hi-C), we show that in Caulobacter crescentus, both transcription rate and transcript length, independent of concurrent translation, drive the formation of domain boundaries. We find that long, highly expressed genes do not form topological boundaries simply through the inhibition of supercoil diffusion. Instead, our results support a model in which long, active regions of transcription drive local decompaction of the chromosome, with these more open regions of the chromosome forming spatial gaps in vivo that diminish contacts between DNA in neighboring domains. These insights into the molecular forces responsible for domain formation in Caulobacter likely generalize to other bacteria and possibly eukaryotes. PMID:27288403

    The mammalian protooncogene homologue of the avian v-ets sequence from the E26 retrovirus consists of two sequentially distinct domains located on different chromosomes. Using somatic cell hybrid panels, the authors have mapped the mammalian homologue of the 5' v-ets-domain to chromosome 11 (ETS1) in man, to chromosome 9 (ets-1) in mouse, and to chromosome D1 (ETS1) in the domestic cat. The mammalian homologue of the 3' v-ets domain was similarly mapped to human chromosome 21 (ETS2), to mouse chromosome 16 (Ets-2), and to feline chromosome C2 (ETS2). Both protooncogenes fell in syntenic groups of homologous linked loci that were conserved among the three species. The occurrence of two distinct functional protooncogenes and their conservation of linkage positions in the three mammalian orders indicate that these two genes have been separate since before the evolutionary divergence of mammals.

  14. Visualization of the chromosome scaffold and intermediates of loop domain compaction in extracted mitotic cells.

    A novel extraction protocol for cells cultured on coverslips is described. Observations of the extraction process in a perfusion chamber reveal that cells of all mitotic stages are not detached from coverslips during extraction, and all stages can be recognized using phase contrast images. We studied the extracted cell morphology and distribution of a major scaffold component - topoisomerase IIalpha, in extracted metaphase and anaphase cells. An extraction using 2M NaCl leads to destruction of chromosomes at the light microscope level. Immunogold studies demonstrate that the only residual structure observed is an axial chromosome scaffold that contains topoisomerase IIalpha. In contrast, mitotic chromosomes are swelled only partially after an extraction using dextran sulphate and heparin, and it appears that this treatment does not lead to total destruction of loop domains. In this case, the chromosome scaffold and numerous structures resembling small rosettes are revealed inside extracted cells. The rosettes observed condense after addition of Mg2+-ions and do not contain topoisomerase IIalpha suggesting that these structures correspond to intermediates of loop domain compaction. We propose a model of chromosome structure in which the loop domains are condensed into highly regular structures with rosette organization. PMID:17029868

    The architecture of human chromosomes in interphase nuclei is still largely unknown. Microscopy studies have indicated that specific regions of chromosomes are located in close proximity to the nuclear lamina (NL). This has led to the idea that certain genomic elements may be attached to the NL, which may contribute to the spatial organization of chromosomes inside the nucleus. However, sequences in the human genome that interact with the NL in vivo have not been identified. Here we construct a high-resolution map of the interaction sites of the entire genome with NL components in human fibroblasts. This map shows that genome-lamina interactions occur through more than 1,300 sharply defined large domains 0.1-10 megabases in size. These lamina-associated domains (LADs) are typified by low gene-expression levels, indicating that LADs represent a repressive chromatin environment. The borders of LADs are demarcated by the insulator protein CTCF, by promoters that are oriented away from LADs, or by CpG islands, suggesting possible mechanisms of LAD confinement. Taken together, these results demonstrate that the human genome is divided into large, discrete domains that are units of chromosome organization within the nucleus. PMID:18463634

    Polyploids constitute more than 80% of angiosperm plant species. Their DNA content is often further increased by endoreplication, which occurs as a part of cell differentiation. Here, we explore the relationship between 3D chromatin architecture, number of genome copies and their origin in the model plant, Arabidopsis thaliana. Spatial proximity between pericentromeric, interstitial and subtelomeric domains of chromosomes 1 and 4 was quantified over a range of distances. The results indicate that average nuclear volume as well as chromatin density increase with the genome copy number. Similar dependence is observed when association of homologous chromosomes (in 2C/ endopolyploid nuclei) and sister chromatid separation (in endopolyploid nuclei) is studied. Moreover, clusters of chromosomal domains are detectable at the spatial scale above microscopy resolution. Subtelomeric, interstitial and pericentromeric chromosomal domains are affected to different extent by these processes, which are modulated by endopolyploidy. This factor influences fusion of heterochromatin as well. Nonetheless, local chromatin architecture of Arabidopsis thaliana depends mainly on endopolyploidy level, and to lesser extend on polyploidy.

  17. Rearrangement of a common cellular DNA domain on chromosome 4 in human primary liver tumors

    International Nuclear Information System (INIS)

    Hepatitis B virus (HBV) DNA integration has been shown to occur frequently in human hepatocellular carcinomas. The authors have investigated whether common cellular DNA domains might be rearranged, possibly by HBV integration, in human primary liver tumors. Unique cellular DNA sequences adjacent to an HBV integration site were isolated from a patient with hepatitis B surface antigen-positive hepatocellular carcinoma. These probes detected rearrangement of this cellular region of chromosomal DNA in 3 of 50 additional primary liver tumors studied. Of these three tumor samples, two contained HBV DNA, without an apparent link between the viral DNA and the rearranged allele; HBV DNA sequences were not detected in the third tumor sample. By use of a panel of somatic cell hybrids, these unique cellular DNA sequences were shown to be located on chromosome 4. Therefore, this region of chromosomal DNA might be implicated in the formation of different tumors at one step of liver cell transformation, possible related to HBV integration

    In higher eukaryotes, the absence of specific sequence motifs marking the origins of replication has been a serious hindrance to the understanding of the mechanisms that regulate the initiation and the maintenance of the replication program in different cell types. In silico analysis of nucleotide compositional skew has predicted the existence, in the germline, of replication N-domains bordered by putative replication origins and where the skew decreases rather linearly as the signature of a progressive inversion of the average fork polarity. Here, from the demonstration that the average fork polarity can be directly extracted from the derivative of replication timing profiles, we develop a wavelet-based pattern recognition methodology to delineate replication U-domains where the replication timing profile is shaped as a U and its derivative as a N. Replication U-domains are robustly found in seven cell lines as covering a significant portion (40-50%) of the human genome where the replication timing data actually displays some plasticity between cell lines. The early replication initiation zones at U-domains borders are found to be hypersensitive to DNase I cleavage, to be associated with transcriptional activity and to present a significant enrichment in insular-binding proteins CTCF, the hallmark of an open chromatin structure. A comparative analysis of genome-wide chromatin interaction (HiC) data shows that replication-U domains correspond to self-interacting structural high order chromatin units of megabase characteristic size. Taken together, these findings provide evidence that the epigenetic compartmentalization of the human genome into autonomous replication U-domains comes along with an extensive remodelling of the threedimensional chromosome architecture during development or in specific diseases. The observed cell specific conservation of the replication timing between the human and mouse genomes strongly suggests that this chromosome organization into

    The distal arm of the fourth (“dot”) chromosome of Drosophila melanogaster is unusual in that it exhibits an amalgamation of heterochromatic properties (e.g., dense packaging, late replication) and euchromatic properties (e.g., gene density similar to euchromatic domains, replication during polytenization). To examine the evolution of this unusual domain, we undertook a comparative study by generating high-quality sequence data and manually curating gene models for the dot chromosome of D. virilis (Tucson strain 15010–1051.88). Our analysis shows that the dot chromosomes of D. melanogaster and D. virilis have higher repeat density, larger gene size, lower codon bias, and a higher rate of gene rearrangement compared to a reference euchromatic domain. Analysis of eight “wanderer” genes (present in a euchromatic chromosome arm in one species and on the dot chromosome in the other) shows that their characteristics are similar to other genes in the same domain, which suggests that these characteristics are features of the domain and are not required for these genes to function. Comparison of this strain of D. virilis with the strain sequenced by the Drosophila 12 Genomes Consortium (Tucson strain 15010–1051.87) indicates that most genes on the dot are under weak purifying selection. Collectively, despite the heterochromatin-like properties of this domain, genes on the dot evolve to maintain function while being responsive to changes in their local environment. PMID:20479145

Methylation mapping in two additional genes with non-imprinted haplotype-dependent ASM, ELK3 and CYP2A7, showed that the CYP2A7 DMR also overlaps a CTCF site. Thus, two features of imprinted domains, highly localized DMRs and allele-specific insulator occupancy by CTCF, can also be found in chromosomal domains with non-imprinted ASM.

    Episodic memory provides information about the “when” of events as well as “what” and “where” they happened. Using functional imaging, we investigated the domain specificity of retrieval-related processes following encoding of complex, naturalistic events. Subjects watched a 42-min TV episode, and 24 h later, made discriminative choices of scenes from the clip during fMRI. Subjects were presented with two scenes and required to either choose the scene that happened earlier in the film (Tempor...

  6. SAP-like domain in nucleolar spindle associated protein mediates mitotic chromosome loading as well as interphase chromatin interaction

    International Nuclear Information System (INIS)

    Highlights: → The SAP-like domain in NuSAP is a functional DNA-binding domain with preference for dsDNA. → This SAP-like domain is essential for chromosome loading during early mitosis. → NuSAP is highly dynamic on mitotic chromatin, as evident from photobleaching experiments. → The SAP-like domain also mediates NuSAP-chromatin interaction in interphase nucleoplasm. -- Abstract: Nucleolar spindle associated protein (NuSAP) is a microtubule-stabilizing protein that localizes to chromosome arms and chromosome-proximal microtubules during mitosis and to the nucleus, with enrichment in the nucleoli, during interphase. The critical function of NuSAP is underscored by the finding that its depletion in HeLa cells results in various mitotic defects. Moreover, NuSAP is found overexpressed in multiple cancers and its expression levels often correlate with the aggressiveness of cancer. Due to its localization on chromosome arms and combination of microtubule-stabilizing and DNA-binding properties, NuSAP takes a special place within the extensive group of spindle assembly factors. In this study, we identify a SAP-like domain that shows DNA binding in vitro with a preference for dsDNA. Deletion of the SAP-like domain abolishes chromosome arm binding of NuSAP during mitosis, but is not sufficient to abrogate its chromosome-proximal localization after anaphase onset. Fluorescence recovery after photobleaching experiments revealed the highly dynamic nature of this NuSAP-chromatin interaction during mitosis. In interphase cells, NuSAP also interacts with chromatin through its SAP-like domain, as evident from its enrichment on dense chromatin regions and intranuclear mobility, measured by fluorescence correlation spectroscopy. The obtained results are in agreement with a model where NuSAP dynamically stabilizes newly formed microtubules on mitotic chromosomes to enhance chromosome positioning without immobilizing these microtubules.

    2016-01-01

    Spatial organization of the genome has important impacts on all aspects of chromosome biology, including transcription, replication, and DNA repair. Frequent interactions of some chromosome domains with specific nuclear compartments, such as the nucleolus, are now well documented using genome-scale methods. However, direct measurement of distance and interaction frequency between loci requires microscopic observation of specific genomic domains and the nucleolus, followed by image analysis to allow quantification. The fluorescent repressor operator system (FROS) is an invaluable method to fluorescently tag DNA sequences and investigate chromosome position and dynamics in living cells. This chapter describes a combination of methods to define motion and region of confinement of a locus relative to the nucleolus in cell's nucleus, from fluorescence acquisition to automated image analysis using two dedicated pipelines.

    FOXP3 is a lineage-specific transcription factor that is required for regulatory T cell development and function. In this study, we determined the crystal structure of the FOXP3 forkhead domain bound to DNA. The structure reveals that FOXP3 can form a stable domain-swapped dimer to bridge DNA in the absence of cofactors, suggesting that FOXP3 may play a role in long-range gene interactions. To test this hypothesis, we used circular chromosome conformation capture coupled with high throughput ...

  11. NMR spectroscopic and bioinformatic analyses of the LTBP1 C-terminus reveal a highly dynamic domain organisation.

    Directory of Open Access Journals (Sweden)

    Ian B Robertson

    Full Text Available Proteins from the LTBP/fibrillin family perform key structural and functional roles in connective tissues. LTBP1 forms the large latent complex with TGFβ and its propeptide LAP, and sequesters the latent growth factor to the extracellular matrix. Bioinformatics studies suggest the main structural features of the LTBP1 C-terminus are conserved through evolution. NMR studies were carried out on three overlapping C-terminal fragments of LTBP1, comprising four domains with characterised homologues, cbEGF14, TB3, EGF3 and cbEGF15, and three regions with no homology to known structures. The NMR data reveal that the four domains adopt canonical folds, but largely lack the interdomain interactions observed with homologous fibrillin domains; the exception is the EGF3-cbEGF15 domain pair which has a well-defined interdomain interface. (15N relaxation studies further demonstrate that the three interdomain regions act as flexible linkers, allowing a wide range of motion between the well-structured domains. This work is consistent with the LTBP1 C-terminus adopting a flexible "knotted rope" structure, which may facilitate cell matrix interactions, and the accessibility to proteases or other factors that could contribute to TGFβ activation.

  12. Aberrant Behaviours of Reaction Diffusion Self-organisation Models on Growing Domains in the Presence of Gene Expression Time Delays

    KAUST Repository

    Seirin Lee, S.

    2010-03-23

    Turing\\'s pattern formation mechanism exhibits sensitivity to the details of the initial conditions suggesting that, in isolation, it cannot robustly generate pattern within noisy biological environments. Nonetheless, secondary aspects of developmental self-organisation, such as a growing domain, have been shown to ameliorate this aberrant model behaviour. Furthermore, while in-situ hybridisation reveals the presence of gene expression in developmental processes, the influence of such dynamics on Turing\\'s model has received limited attention. Here, we novelly focus on the Gierer-Meinhardt reaction diffusion system considering delays due the time taken for gene expression, while incorporating a number of different domain growth profiles to further explore the influence and interplay of domain growth and gene expression on Turing\\'s mechanism. We find extensive pathological model behaviour, exhibiting one or more of the following: temporal oscillations with no spatial structure, a failure of the Turing instability and an extreme sensitivity to the initial conditions, the growth profile and the duration of gene expression. This deviant behaviour is even more severe than observed in previous studies of Schnakenberg kinetics on exponentially growing domains in the presence of gene expression (Gaffney and Monk in Bull. Math. Biol. 68:99-130, 2006). Our results emphasise that gene expression dynamics induce unrealistic behaviour in Turing\\'s model for multiple choices of kinetics and thus such aberrant modelling predictions are likely to be generic. They also highlight that domain growth can no longer ameliorate the excessive sensitivity of Turing\\'s mechanism in the presence of gene expression time delays. The above, extensive, pathologies suggest that, in the presence of gene expression, Turing\\'s mechanism would generally require a novel and extensive secondary mechanism to control reaction diffusion patterning. © 2010 Society for Mathematical Biology.

    PRDM9 is the sole hybrid sterility gene identified so far in vertebrates. PRDM9 gene encodes a protein with an immensely variable zinc-finger (ZF) domain that determines the site of meiotic recombination hotspots genome-wide. In this study, the terminal ZF domain of PRDM9 on bovine chromosome 1 and its paralog on chromosome 22 were characterized in 225 samples from five ruminant species (cattle, yak, mithun, sheep and goat). We found extraordinary variation in the number of PRDM9 zinc fingers (6 to 12). We sequenced PRDM9 ZF encoding region from 15 individuals (carrying the same ZF number in both copies) and found 43 different ZF domain sequences. Ruminant zinc fingers of PRDM9 were found to be diversifying under positive selection and concerted evolution, specifically at positions involved in defining their DNA-binding specificity, consistent with the reports from other vertebrates such as mice, humans, equids and chimpanzees. ZF-encoding regions of the PRDM7, a paralog of PRDM9 on bovine chromosome 22 and on unknown chromosomes in other studied species were found to contain 84 base repeat units as in PRDM9, but there were multiple disruptive mutations after the first repeat unit. The diversity of the ZFs suggests that PRDM9 may activate recombination hotspots that are largely unique to each ruminant species. PMID:27203728

  5. High-resolution in situ hybridization analysis on the chromosomal interval 61C7-61C8 of Drosophila melanogaster reveals interbands as open chromatin domains.

    2016-06-01

    Eukaryotic chromatin is organized in contiguous domains that differ in protein binding, histone modifications, transcriptional activity, and in their degree of compaction. Genome-wide comparisons suggest that, overall, the chromatin organization is similar in different cells within an organism. Here, we compare the structure and activity of the 61C7-61C8 interval in polytene and diploid cells of Drosophila. By in situ hybridization on polytene chromosomes combined with high-resolution microscopy, we mapped the boundaries of the 61C7-8 interband and of the 61C7 and C8 band regions, respectively. Our results demonstrate that the 61C7-8 interband is significantly larger than estimated previously. This interband extends over 20 kbp and is in the range of the flanking band domains. It contains several active genes and therefore can be considered as an open chromatin domain. Comparing the 61C7-8 structure of Drosophila S2 cells and polytene salivary gland cells by ChIP for chromatin protein binding and histone modifications, we observe a highly consistent domain structure for the proximal 13 kbp of the domain in both cell types. However, the distal 7 kbp of the open domain differs in protein binding and histone modification between both tissues. The domain contains four protein-coding genes in the proximal part and two noncoding transcripts in the distal part. The differential transcriptional activity of one of the noncoding transcripts correlates with the observed differences in the chromatin structure between both tissues. The significance of our findings for the organization and structure of open chromatin domains will be discussed. PMID:26520107

    CERN Document Server

    Michieletto, Davide; Marenduzzo, Davide

    2016-01-01

    One of the most important problems in development is how epigenetic domains can be first established, and then maintained, within cells. To address this question, we propose a framework which couples 3D chromatin folding dynamics, to a "recolouring" process modelling the writing of epigenetic marks. Because many intra-chromatin interactions are mediated by bridging proteins, we consider a "two-state" model with self-attractive interactions between two epigenetic marks which are alike (either active or inactive). This model displays a first-order-like transition between a swollen, epigenetically disordered, phase, and a compact, epigenetically coherent, chromatin globule. If the self-attraction strength exceeds a threshold, the chromatin dynamics becomes glassy, and the corresponding interaction network freezes. By modifying the epigenetic read-write process according to more biologically-inspired assumptions, our polymer model with recolouring recapitulates the ultrasensitive response of epigenetic switches t...

  11. Organisational Learning: Theoretical Shortcomings and Practical Challenges

    Directory of Open Access Journals (Sweden)

    Jon Aarum Andersen

    2014-05-01

    Full Text Available This paper addresses two problems related to learning and the use of knowledge at work. The first problem is the theoretical shortcomings stemming from the controversy between three different concepts of ‘organisational learning.’ In order to enhance scholarship in this field the notion that organisations - as organisations - can learn need to be rejected for theoretical and empirical reasons. The metaphorical use of ‘organisational learning’ creates only confusion. Learning is a process and knowledge is the outcome of that process. It is argued that learning and knowledge is only related to individuals. Knowledge is thus the individual capability to draw distinctions, within a domain of action, based on an appreciation of context or theory. Consequently, knowledge becomes organisational when it is created, developed and transmitted to other individuals in the organisation. In a strict sense knowledge becomes organisational when employees use it and act based on generalisations due to the rules and procedures found in their organisation. The gravest problem is practical challenges due to the fact that the emphasis on learning, knowledge and competence of the working force do not materialize in the application of the knowledge acquired. It is evident that employees do not use their increased knowledge. However, we do not know why they do not use it. An enormous waste of money is spent on learning and knowledge in organisations which does not yield what is expected. How can managers act in order to enhance the application of increased knowledge possessed by the workforce?

    Using an original high-salt extraction protocol, we observed a novel chromosome substructure, referred to as the peripheral chromosome scaffold. This chromosome domain contained the perichromosomal layer proteins pKi-67, B23/nucleophosmin and fibrillarin, but no DNA fragments (i.e., the loop domain bases were not associated with the peripheral scaffold). Modern models of chromosome organization do not predict the existence of a peripheral chromosome scaffold domain, and thus our observations have conceptual implications for understanding chromosome architecture.

  16. Microtubule self-organisation by reaction-diffusion processes causes collective transport and organisation of cellular particles

    Directory of Open Access Journals (Sweden)

    Demongeot Jacques

    2004-06-01

    Full Text Available Abstract Background The transport of intra-cellular particles by microtubules is a major biological function. Under appropriate in vitro conditions, microtubule preparations behave as a 'complex' system and show 'emergent' phenomena. In particular, they form dissipative structures that self-organise over macroscopic distances by a combination of reaction and diffusion. Results Here, we show that self-organisation also gives rise to a collective transport of colloidal particles along a specific direction. Particles, such as polystyrene beads, chromosomes, nuclei, and vesicles are carried at speeds of several microns per minute. The process also results in the macroscopic self-organisation of these particles. After self-organisation is completed, they show the same pattern of organisation as the microtubules. Numerical simulations of a population of growing and shrinking microtubules, incorporating experimentally realistic reaction dynamics, predict self-organisation. They forecast that during self-organisation, macroscopic parallel arrays of oriented microtubules form which cross the reaction space in successive waves. Such travelling waves are capable of transporting colloidal particles. The fact that in the simulations, the aligned arrays move along the same direction and at the same speed as the particles move, suggest that this process forms the underlying mechanism for the observed transport properties. Conclusions This process constitutes a novel physical chemical mechanism by which chemical energy is converted into collective transport of colloidal particles along a given direction. Self-organisation of this type provides a new mechanism by which intra cellular particles such as chromosomes and vesicles can be displaced and simultaneously organised by microtubules. It is plausible that processes of this type occur in vivo.

    2015-01-01

    How the same DNA sequences can function in the three-dimensional architecture of interphase nucleus, fold in the very compact structure of metaphase chromosomes and go precisely back to the original interphase architecture in the following cell cycle remains an unresolved question to this day. The strategy used to address this issue was to analyze the correlations between chromosome architecture and the compositional patterns of DNA sequences spanning a size range from a few hundreds to a few thousands Kilobases. This is a critical range that encompasses isochores, interphase chromatin domains and boundaries, and chromosomal bands. The solution rests on the following key points: 1) the transition from the looped domains and sub-domains of interphase chromatin to the 30-nm fiber loops of early prophase chromosomes goes through the unfolding into an extended chromatin structure (probably a 10-nm “beads-on-a-string” structure); 2) the architectural proteins of interphase chromatin, such as CTCF and cohesin sub-units, are retained in mitosis and are part of the discontinuous protein scaffold of mitotic chromosomes; 3) the conservation of the link between architectural proteins and their binding sites on DNA through the cell cycle explains the “mitotic memory” of interphase architecture and the reversibility of the interphase to mitosis process. The results presented here also lead to a general conclusion which concerns the existence of correlations between the isochore organization of the genome and the architecture of chromosomes from interphase to metaphase.

  14. Chromosomal aberration

    International Nuclear Information System (INIS)

    Chromosomal aberrations are classified into two types, chromosome-type and chromatid-type. Chromosom-type aberrations include terminal deletion, dicentric, ring and interstitial deletion, and chromatid-type aberrations include achromatic lesion, chromatid deletion, isochromatid deletion and chromatid exchange. Clastogens which induce chromosomal aberration are divided into ''S-dependent'' agents and ''S-independent''. It might mean whether they can induce double strand breaks independent of the S phase or not. Double strand breaks may be the ultimate lesions to induce chromosomal aberrations. Caffeine added even in the G2 phase appeared to modify the frequency of chromatid aberrations induced by X-rays and mitomycin C. Those might suggest that the G2 phase involves in the chromatid aberration formation. The double strand breaks might be repaired by ''G2 repair system'', the error of which might yield breakage types of chromatid aberrations and the by-pass of which might yield chromatid exchanges. Chromosome-type aberrations might be formed in the G1 phase. (author)

    2015-11-01

    What a living organism looks like and how it works and what are its components-all this is encoded on DNA, the genetic blueprint. Consequently, the way to change an organism is to change its genetic information. Since the first pieces of recombinant DNA have been used to transform cells in the 1970s, this approach has been enormously extended. Bigger and bigger parts of the genetic information have been exchanged or added over the years. Now we are at a point where the construction of entire chromosomes becomes a reachable goal and first examples appear. This development leads to fundamental new questions, for example, about what is possible and desirable to build or what construction rules one needs to follow when building synthetic chromosomes. Here we review the recent progress in the field, discuss current challenges and speculate on the appearance of future synthetic chromosomes. PMID:26111960

    Full Text Available Modern organisations are confronted with enormous challenges. The need to continuously adapt to changing environments represents a main challenge for modern organisations. In order to adapt to the requirements of modern environments more easily and more rapidly, organisations become connected into networks. A network organisation is fast becoming a favourite form of the modern organisation. On the basis of an analysis of members in the field of network organisations, this contribution presents the dimensions and definitions of network organisations. In the follow-up, the starting point for a theoretical explanation of network organisations and their different existing forms is presented. The emphasis of the empirical part of the contribution focuses on presenting an analysis of forms of network organisations that are present in Slovenia from the perspective of their shape, development and actual state. Based on an analysis of relevant documentation, it may be concluded that it was the institutional environment which initiated and directed the start-up processes that led to the establishment of contemporary network organisations within Slovenia.

  13. Organisational Learning - A Global View

    International Nuclear Information System (INIS)

    This paper will discuss the concept of organisational learning and its application to NPP. The concept outlined in this paper substantially extends the operating experience feedback process currently practiced in NPP. Organisational learning has emerged from economics and business administration where measures related to this concept have been applied to increase economic efficiency and return. Such organisations are designed to achieve specific objectives by using specific means and resources. For these organisations, organisational learning is of utmost importance especially in changing environments, because it drives the systematic and continuous adaptation and self-improvement of an organisation in order to better carry out its missions and to better fulfil the economic, legal, political, scientific, social, and technological requirements of the environment. In the nuclear industry, besides design nuclear safety is guaranteed by an efficient safety management. Safety management includes the continuous monitoring, evaluation, and improvement of nuclear safety. Organisational learning is an essential element of safety management, and safety management is to be considered as a particular framework for organisational learning. To be efficient, organisational learning, like safety management, has to rely on core values of a good safety culture like e.g. questioning attitude, and openness to criticism. Chapter 2 of the paper elaborates on the definition of organisational learning and its main elements. Chapter 3 discusses the current status regarding the organisational learning system in German NPP. Chapter 4 presents concept and implementation status of an organisational learning system developed by the Unterweser NPP and GRS. The paper concludes with lessons learned up to now

  16. Expression cloning and chromosomal mapping of the leukocyte activation antigen CD97, a new seven-span transmembrane molecule of the secretin receptor superfamily with an unusual extracellular domain

    1995-08-15

    CD97 is a monomeric glycoprotein of 75 to 85 kDa that is induced rapidly on the surface of most leukocytes upon activation. We herein report the isolation of a cDNA encoding human CD97 by expression cloning in COS cells. The 3-kb cDNA clone encodes a mature polypeptide chain of 722 amino acids with a predicted molecular mass of 79 kDa. Within the C-terminal part of the protein, a region with seven hydrophobic segments was identified, suggesting that CD97 is a seven-span transmembrane molecule. Sequence comparison indicates that CD97 is the first leukocyte Ag in a recently described superfamily that includes the receptors for secretin, calcitonin, and other mammalian and insect peptide hormones. Different from these receptors, CD97 has an extended extracellular region of 433 amino acids that possesses three N-terminal epidermal growth factor-like domains, two of them with a calcium-binding site, and single Arg-Gly-Asp (RGD) motif. The existence of structural elements characteristic for extracellular matrix proteins in a seven-span transmembrane molecule makes CD97 a receptor potentially involved in both adhesion and signaling processes early after leukocyte activation. The gene encoding CD97 is localized on chromosome 19 (19p13.12-13.2).

    Over the last half century, knowledge about genetics, genetic testing, and its complexity has flourished. Completion of the Human Genome Project provided a foundation upon which the accuracy of genetics, genomics, and integration of bioinformatics knowledge and testing has grown exponentially. What is lagging, however, are efforts to reach and engage nurses about this rapidly changing field. The purpose of this article is to familiarize nurses with several frequently ordered genetic tests including chromosomes and fluorescence in situ hybridization followed by a comprehensive review of chromosome microarray. It shares the complexity of microarray including how testing is performed and results analyzed. A case report demonstrates how this technology is applied in clinical practice and reveals benefits and limitations of this scientific and bioinformatics genetic technology. Clinical implications for maternal-child nurses across practice levels are discussed. PMID:27276104

    Full Text Available Purpose: The aim of this article is to analyse the theoretical views and results of empirical research concerning the relation between organisational learning (OL and organisational performance (OP. Methodology: The study was carried out through extensive literature research, including relevant literature review from databases such as ProQuest, Elsevier, Emerald and EBSCO (the phrases: “organisational learning”, “learning organisation” and “organisational performance” were searched in the keywords, titles or abstracts. Findings: From a theoretical point of view, the relation between OL and OP is neither obvious nor clear, but the analysis of the empirical studies allows one to assume that OL has an essential impact on OP. However, differences in the strength of the relation were shown and some contradictions related to the presence of the relation between OL and selected (mostly financial performance aspects identified. Furthermore, the article discusses the significant differences and inconsistencies in the methods of measuring OL, measuring OP, selecting contextual factors and adopted methods of data analysis. Implications: Inconsistencies and gaps found in the studies of the relationship between OL and OP made it possible to designate the direction for promising further research. Value: The article presents valuable insight through its in-depth, critical analysis of the organisational learning and organisational outcomes. First and foremost, this indicates that the formula of the previous empirical studies does not allow for the development of precise solutions pertaining to organisational learning management for the benefit of OP improvement.

  5. Diffusing Polymers in Confined Microdomains and Estimation of Chromosomal Territory Sizes from Chromosome Capture Data

    Amitai, A.; Holcman, D.

    2013-06-01

    Is it possible to extract the size and structure of chromosomal territories (confined domain) from the encounter frequencies of chromosomal loci? To answer this question, we estimate the mean time for two monomers located on the same polymer to encounter, which we call the mean first encounter time in a confined microdomain (MFETC). We approximate the confined domain geometry by a harmonic potential well and obtain an asymptotic expression that agrees with Brownian simulations for the MFETC as a function of the polymer length, the radius of the confined domain, and the activation distance radius ɛ at which the two searching monomers meet. We illustrate the present approach using chromosome capture data for the encounter rate distribution of two loci depending on their distances along the DNA. We estimate the domain size that restricts the motion of one of these loci for chromosome II in yeast.

    Rumex hastatulus is the North American endemic dioecious plant with heteromorphic sex chromosomes. It is differentiated into two chromosomal races: Texas (T) race characterised by a simple XX/XY sex chromosome system and North Carolina (NC) race with a polymorphic XX/XY1Y2 sex chromosome system. The gross karyotype morphology in NC race resembles the derived type, but chromosomal changes that occurred during its evolution are poorly understood. Our C-banding/DAPI and fluorescence in situ hybridization (FISH) experiments demonstrated that Y chromosomes of both races are enriched in DAPI-positive sequences and that the emergence of polymorphic sex chromosome system was accompanied by the break of ancestral Y chromosome and switch in the localization of 5S rDNA, from autosomes to sex chromosomes (X and Y2). Two contrasting domains were detected within North Carolina Y chromosomes: the older, highly heterochromatinised, inherited from the original Y chromosome and the younger, euchromatic, representing translocated autosomal material. The flow-cytometric DNA estimation showed ∼3.5 % genome downsizing in the North Carolina race. Our results are in contradiction to earlier reports on the lack of heterochromatin within Y chromosomes of this species and enable unambiguous identification of autosomes involved in the autosome-heterosome translocation, providing useful chromosome landmarks for further studies on the karyotype and sex chromosome differentiation in this species.

    Full Text Available This article uses the case of a regional intermediary organisation to investigate organisational memory (OM and its contribution to knowledge management and activities in evaluations. Understanding of, and accessing OM is critical for participatory evaluations. The aim of the article is to reflect on the OM of a non-governmental organisation (NGO and what implicationsthe structural changes in OM over the organisation’s life cycle have for evaluators. It further aims to advocate an awareness of OM and explains how evaluators can access and utilise it more effectively. Evaluators need to have an understanding of OM, and to take more responsibility for disseminating results to enhance it. This case study reflects on a retrospective case example of a regional NGO. The report reflects the development and structure of the life cycle of the organisation. The data collection included in-depth interviews with staff members and other key stakeholders, engagement with beneficiary organisations and donors, and analyses of documents, electronic files and audio-visual material. Since OM survives after the demise of an organisation, and is accessible through directories, it is important for the evaluator to include historical information. Specific implications for evaluators include the ability to access OM through directories and networks of the organisation. As evaluators hold OM of all the organisations they have engaged with, they also have a responsibility to share knowledge. The key findings of this study illustrate the importance of accessing the memory and historical information of the organisation. Understanding OM enhances the in-depth comprehension of the activity, project or programme under investigation, and the collective knowledge generated as a result of it.

    In everyone's day-to-day jobs there is constant need to deal with current and newly detected matters. This is now a world of immediacy, driven by the cadence of the business and its needs. These concerns should not be ignored, as failing to deal with these issues would not bode well for the future. It is essential that the gears are kept spinning. The challenge for any security organisation is to identify its short-term tactical requirements, while developing longer-term strategic needs. Once done, the differences can be accounted for and strides can be made toward a desired future state. This paper highlights several steps that the author and his team have taken in their own journey. There is no magic answer, each organisation will have its own unique challenges. Nevertheless, some of the approaches to building a strategic security organisation described in this paper are applicable to all organisations, irrespective of their size. PMID:27318284

    Organisational culture is presented as a complex concept underpinned by specific values, beliefs and assumptions that account for the way things are done. Strong organisational cultures and a number of other attributes are highlighted as having influence on performance. The role of leadership is recognised as key to facilitating cultural change, as is the use of approaches which clarify values and highlight contradictions between espoused culture and culture in practice. A three-year study in which a consultant nurse post in critical care was operationalised demonstrated the achievement of an organisational culture with positive impact on the unit in which it was based, on practitioners and their practice, and also on the trust. Transformational leadership combined with other facilitative processes, expertise in the practice of nursing, and other subroles of the consultant nurse are further highlighted as influential.

    Purpose - The purpose of this paper is to fill an apparent gap in the literature addressing issues of leadership and change - the development and activities of constructing and leading sports sciences and medicine professions, and similarly, the construction and leadership of multidisciplinary/inter-disciplinary organisations that practice sports sciences and medicine. Design/methodology/approach - This study incorporated explorations through conducting both interviews and survey questionnaires with members of Sports Medicine Australia (SMA). The interviews (qualitative) were semi-structured and asked questions addressing what changed, why change and how change was implemented. Findings - The health sciences and medicine professions moving to specialised sports sciences and medicine disciplines and SMA, evolved through forces driving the need for change (legitimacy, resource dependency, positioning and core competencies). Practical implications - The knowledge developed from understanding activities of change that traditional professions conducted to become specialised Disciplines and parallel changes in a single Discipline organisation evolving to an umbrella organisation (SMA), comprised a membership of specialised Disciplines, can act as a catalyst for inquiry by other professional and organisational groups. Originality/value - The findings of this study contributes to the literature investigating change in professional and organisations fields. More specifically, this study promotes inquiry into leadership practices of sports sciences and medicine, as contributors to the field of health services. PMID:26764964

    International Nuclear Information System (INIS)

    The paper relates to integrating technology in a changing organisation of Elf Aquitaine. There is a strong pressure to cut costs and be more effective in the company's operations. A process was initiated in 1994 to re-analyse its E and P (Exploration and Production) research and development (R and D) in order to enhance its alignment with the company assets needs, with a subsequent prioritization of R and D projects. The integration included a strategy for cooperation with other oil and service companies. The author presents the process set up to align the company's R and D program to the business needs of its operations, the various levels of cooperation used, and finally an illustration, in the domain of the geosciences, of the various facets of the ongoing cultural revolution which is required to reach a true integration. 11 figs

  4. Mitotic chromosome structure

    International Nuclear Information System (INIS)

    Mounting evidence is compiling linking the physical organizational structure of chromosomes and the nuclear structure to biological function. At the base of the physical organizational structure of both is the concept of loop formation. This implies that physical proximity within chromosomes is provided for otherwise distal genomic regions and thus hierarchically organizing the chromosomes. Together with entropy many experimental observations can be explained with these two concepts. Among the observations that can be explained are the measured physical extent of the chromosomes, their shape, mechanical behavior, the segregation into territories (chromosomal and territories within chromosomes), the results from chromosome conformation capture experiments, as well as linking gene expression to structural organization.

    2009-04-01

    Implementing the World Health Organisation (WHO) Framework Convention on Tobacco Control (FCTC) relies heavily on enforcement. Little is known of the way different enforcement agencies operate, prioritise or network. A questionnaire was sent to representatives of the International Federation of Environmental Health (IFEH) in 36 countries. Tobacco control was given low priority. Almost two thirds did not have any tobacco control policy. A third reported their organisation had worked with other agencies on tobacco control. Obstacles to addressing tobacco control included a lack of resources (61%) and absence of a coherent strategy (39%).

  11. 'Ethos' Enabling Organisational Knowledge Creation

    Science.gov (United States)

    Matsudaira, Yoshito

    This paper examines knowledge creation in relation to improvements on the production line in the manufacturing department of Nissan Motor Company and aims to clarify embodied knowledge observed in the actions of organisational members who enable knowledge creation will be clarified. For that purpose, this study adopts an approach that adds a first, second, and third-person's viewpoint to the theory of knowledge creation. Embodied knowledge, observed in the actions of organisational members who enable knowledge creation, is the continued practice of 'ethos' (in Greek) founded in Nissan Production Way as an ethical basis. Ethos is knowledge (intangible) assets for knowledge creating companies. Substantiated analysis classifies ethos into three categories: the individual, team and organisation. This indicates the precise actions of the organisational members in each category during the knowledge creation process. This research will be successful in its role of showing the indispensability of ethos - the new concept of knowledge assets, which enables knowledge creation -for future knowledge-based management in the knowledge society.

  5. Understanding bullying in healthcare organisations.

    Science.gov (United States)

    Allen, Belinda

    2015-12-01

    Bullying is a pervasive problem in healthcare organisations. Inquiries and reports on patient care and poor practice in the NHS have emphasised the substantial negative effects this behaviour may have on patient care. If bullying is to be addressed, it is crucial we develop clarity about what behaviours constitute bullying and how these behaviours differ from other negative behaviours in the workplace. It is important that we recognise the extent of the problem; statistics on the prevalence of bullying are likely to be an underestimate because of under-reporting of bullying. Effective interventions may only be designed and implemented if there is knowledge about what precipitates bullying and the magnitude of the changes required in organisations to tackle bullying. Individuals should also be aware of the options that are available to them should they be the target of bullying behaviour and what they should do if they witness bullying in their workplace.

    The paper examines in the context of financial reporting, the controls that organisations have in place to manage spreadsheet risk and errors. There has been widespread research conducted in this area, both in Ireland and internationally. This paper describes a study involving 19 participants (2 case studies and 17 by survey) from Ireland. Three areas are examined; firstly, the extent of spreadsheet usage, secondly, the level of complexity employed in spreadsheets, and finally, the controls in place regarding spreadsheets. The findings support previous findings of Panko (1998), that errors occur frequently in spreadsheets and that there is little or unenforced controls employed, however this research finds that attitudes are changing with regard to spreadsheet risk and that one organisation is implementing a comprehensive project regarding policies on the development and control of spreadsheets. Further research could be undertaken in the future to examine the development of a "best practice model" both for t...

  11. Feminine leadership and organisational culture

    Directory of Open Access Journals (Sweden)

    Andreea-Simona Saseanu

    2014-05-01

    Full Text Available People in general, leaders especially, are influenced by the organisational culture and the other way around. Organisational culture represents a determining factor regarding the display of leadership, since these two processes create each other, adding value and consistency to one another. Moreover, organisational culture can be created and developed in a fluctuant business environment, in which the external factors influence its progress. The development of society has incessantly been emphasized by the relationship between the sexes, by their individual evolution, but also by the interdependency between them. Although there is increasingly more talk about gender equality, in many countries, the social as well as economical chances and opportunities are not equal for women and men. Gradually, women have been through a series of changes related to education, rights and obligations. However, the number of women leaders has always been much lower than the number of men leaders. The personality traits of leaders significantly influence the leadership style and the way in which they are perceived by their subordinates, all this having a major impact on the overall performances of the organisation. In this manner, depending on the gender (masculine/feminine, we can state that one could observe certain personality traits that are characteristic to women and others specific to men, leaving their mark on the leadership method and on the leadership style adopted of each of them. Considering the fact that, in the current turbulent economic environment, certain qualities such as flexibility, intuition, development of communication networks and motivating the employees represent values that are considered to be “feminine”, one can assert that, in this case, gender is an opportunity. However, if we should take into consideration the impact of culture, of certain mentalities and misconceptions that are still present, regarding the woman’s standing in

  13. Communication in third sector organisations

    Directory of Open Access Journals (Sweden)

    Patricia Durán-Bravo, M.A.

    2010-01-01

    Full Text Available Third sector organisations favour the social development due to their capacity to produce human and social capital in society (Putman, 2001. In order to achieve social welfare third sector organisations need to produce a positive change in the relations among individuals, groups and institutions in a society. The expectations about the third sector organisations’ transparency and capacity to tackle social problems are increasing worldwide. In Mexico, this problematic is more complex because there is a low level of professionalism, transparency, accountability and participation culture in the organized civil society (ITAM, 2010. The development of the organized civil society in Mexico will depend to a great extent on its capacity to communicate its values to society and achieve a cultural and social change. Therefore, the third sector organisations must adopt strategic initiatives to reinforce their credibility and reputation, because the public and private donors are increasingly more demanding in their criteria to grant resources to social projects; and because the Mexican society has a low participation level and faces increasingly more complex social problems.

    2013-11-01

    Chromosomes must be highly compacted and organized within cells, but how this is achieved in vivo remains poorly understood. We report the use of chromosome conformation capture coupled with deep sequencing (Hi-C) to map the structure of bacterial chromosomes. Analysis of Hi-C data and polymer modeling indicates that the Caulobacter crescentus chromosome consists of multiple, largely independent spatial domains that are probably composed of supercoiled plectonemes arrayed into a bottle brush-like fiber. These domains are stable throughout the cell cycle and are reestablished concomitantly with DNA replication. We provide evidence that domain boundaries are established by highly expressed genes and the formation of plectoneme-free regions, whereas the histone-like protein HU and SMC (structural maintenance of chromosomes) promote short-range compaction and the colinearity of chromosomal arms, respectively. Collectively, our results reveal general principles for the organization and structure of chromosomes in vivo. PMID:24158908

  6. Realising the organisational learning opportunities

    International Nuclear Information System (INIS)

    An aspect of proactive safety management is learning lessons from unforeseen events. As BNFL has expanded and extended its nuclear services to many more sites, the potential for organisational learning has grown, but sharing through informal networking has become progressively harder. This potential problem has been solved by implementing formalised company-wide arrangements to turn incidents and accidents into organisational learning opportunities through a system called 'Learning from Experience' (LFE). LFE enables event causes and corrective actions to be identified and shared across all BNFL's sites, initially in the UK but ultimately throughout the world. The result is prevention of events having similar causes, and development of a learning culture which breaks down the barriers to adopting best practice'. Key aspects of the system are: Applying root cause analysis to all significant events; Logging all events, their causes and corrective actions onto a Company-wide database; Screening the database regularly by locally appointed Feedback Co-ordinators trained in identifying learning opportunities and knowledgeable of their own business area, and; Placing and tracking actions to prevent similar events at local Event Review Meetings. The paper describes the implementation and initial experience in operation of the LFE system, which is seen as a significant step towards becoming an expanding and learning company with no accidents or incidents.

    Full Text Available The primary goal of all organisations is efficiency of human resources. Therefore activities as HR controlling, performance management but also cutting costs are the main theme. Current organisations need to monitor human resources to keep their competitiveness. Thus paper describes the key factor of organisational efficiency - employee education, talent management and the necessity to retain skilled employees. The aim of the paper is to reveal the current approach in organisations to education and learning based on primary survey of employees. The data were collected using quantitative primary survey in Czech organisations across sectors. The questionnaire was compiled based on the theoretical background. The paper has been processed based on the analysis of secondary sources, outcome synthesis and the evaluation of results of a questionnaire survey. The data were analysed using descriptive statistic, correlation analysis and factor analysis. The SPSS programme was used for the analyses. The outcomes were categorized and the analyses revealed the main factors affecting organisational approach to employee learning and development. The results identify three possible approaches in organisations to employee learning and development. The first type of organisations educates employees by their own rules, second type does not support education of employees in any way, it is only an interest of employees themselves and thirdly knowledgeable employees were identified as those employees do as much as possible to learn and grow and they choose job position in order to develop constantly. The results can be taken into account in further analysis and in organisation of adult education.

  1. Simultaneous Attacks by Terrorist Organisations

    2013-12-01

    Full Text Available While terror attacks that are a part of a coordinated effort receive attention in the popular media, they have not received much attention in the academic literature. The decision to carry out simultaneous attacks should be examined as one of the choices a terrorist organisation makes about the method of attack. Determining the impact of simultaneous attacks vis-à-vis a single attack can explain why groups would use this method. Up to one quarter of all attacks coded in two major databases, GTD and ITERATE, may be part of a simultaneous campaign. Empirical analysis shows simultaneous attacks are more likely to be successful and cause more fatalities, though not in a one-to-one fashion. These results underline the importance of considering simultaneous attacks in empirical analysis.

    Directory of Open Access Journals (Sweden)

    Kwasi Dartey-Baah, PhD

    2011-10-01

    Full Text Available Public sector reforms have been on the agenda of a number of governments, including Ghana and development agencies such as the World Bank. From the review of existing literature, it is notable that the impact of leadership and organisational culture on the performance of organisations is significant either positively or negatively and therefore essential factors in ensuring a reformed and more efficient public sector, especially in developing countries. This paper looks at the general discussions on leadership and organisational culture narrowed down to the Ghanaian context. Furthermore, the relationship between transformational leadership and organisational culture and their relevance in public sector organisations in Ghana are touched on. This conceptual paper identifies that leadership and organisational culture play a very important role in the performance of public sector organisations and in particularly the transformational style of leadership seems to result in more innovative and dynamic practices in public sector organisations.

  9. 'Organised' cervical screening 45 years on: How consistent are organised screening practices?

    Williams, Jane H; Carter, Stacy M; Rychetnik, Lucie

    2014-11-01

    Organised screening programmes have been remarkably successful in reducing incidence and mortality from cervical cancer, while opportunistic screening varies in its effectiveness. Experts recommend that cervical screening or HPV testing be carried out only in the context of an organised programme. We sought to answer the following study questions: What does it mean for a cervical screening programme to be organised? Is there a place for opportunistic screening (in an organised programme)? We reviewed 154 peer-reviewed papers on organised and opportunistic approaches to cervical screening published between 1970 and 2014 to understand how the term 'organised' is used, formally and in practice. We found that despite broad recognition of a prescriptive definition of organisation, in practice the meaning of organisation is much less clear. Our review revealed descriptions of organised programmes that differ significantly from prescribed norms and from each other, and a variety of ways that opportunistic and organised programmes intersect. We describe the breadth of the variation in cervical cancer screening programmes and examine the relationships and overlaps between organised and opportunistic screening. Implications emerging from the review include the need to better understand the breadth of organisation in practice, the drivers and impacts of opportunistic screening and the impact of opportunistic screening on population programme outcomes. Appreciation of the complexity of cervical screening programmes will benefit both screeners and women as programmes are changed to reflect a partially vaccinated population, new evidence and new technologies.

    2013-01-01

    It is now well established that plants have an important place in studies of sex chromosome evolution because of the repeated independent evolution of separate sexes and sex chromosomes. There has been considerable recent progress in studying plant sex chromosomes. In this review, I focus on how these recent studies have helped clarify or answer several important questions about sex chromosome evolution, and I shall also try to clarify some common misconceptions. I also outline future work that will be needed to make further progress, including testing some important ideas by genetic, molecular, and developmental approaches. Systems with different ages can clearly help show the time course of events during changes from an ancestral co-sexual state (hermaphroditism or monoecy), and I will also explain how different questions can be studied in lineages whose dioecy or sex chromosomes evolved at different times in the past.

  9. Specific patterns of gene space organisation revealed in wheat by using the combination of barley and wheat genomic resources

    Directory of Open Access Journals (Sweden)

    Waugh Robbie

    2010-12-01

    Full Text Available Abstract Background Because of its size, allohexaploid nature and high repeat content, the wheat genome has always been perceived as too complex for efficient molecular studies. We recently constructed the first physical map of a wheat chromosome (3B. However gene mapping is still laborious in wheat because of high redundancy between the three homoeologous genomes. In contrast, in the closely related diploid species, barley, numerous gene-based markers have been developed. This study aims at combining the unique genomic resources developed in wheat and barley to decipher the organisation of gene space on wheat chromosome 3B. Results Three dimensional pools of the minimal tiling path of wheat chromosome 3B physical map were hybridised to a barley Agilent 15K expression microarray. This led to the fine mapping of 738 barley orthologous genes on wheat chromosome 3B. In addition, comparative analyses revealed that 68% of the genes identified were syntenic between the wheat chromosome 3B and barley chromosome 3 H and 59% between wheat chromosome 3B and rice chromosome 1, together with some wheat-specific rearrangements. Finally, it indicated an increasing gradient of gene density from the centromere to the telomeres positively correlated with the number of genes clustered in islands on wheat chromosome 3B. Conclusion Our study shows that novel structural genomics resources now available in wheat and barley can be combined efficiently to overcome specific problems of genetic anchoring of physical contigs in wheat and to perform high-resolution comparative analyses with rice for deciphering the organisation of the wheat gene space.

    Recent studies have identified oncogenic lesions in Philadelphia chromosome-positive (Ph+)  acute lymphoblastic leukemia (ALL) and ABL1 kinase mutations that confer resistance to tyrosine kinase inhibitors. We sought to determine the prevalence and clinical impact of these lesions in patients on CALGB 10001, a previously reported Phase II study of imatinib, chemotherapy, and hematopoietic cell transplant in adult Ph + ALL. Of the 58 enrolled, 22 relapsed. By direct sequencing, an ABL1 kinase mutation known to induce imatinib resistance was present at relapse in 13 of 20. Using quantitative PCR assays, the mutations were detectable at diagnosis or early during treatment in most (62%) relapsed patients. Aberrations in IKZF1, CDKN2A/B, and PAX5 were assessed in 28 samples using SNP arrays and genomic DNA sequencing. Of these, 22 (79%) had IKZF1 deletion. The combination of IKZF1 deletion and p210 BCR-ABL1 (p < 0.0001), high white blood cell count (p = 0.021), and minimal residual disease (p = 0.013) were associated with worse disease-free survival.

The definitions of success and methodological approaches are discussed, and suggestions for improving empirical research in this area are presented. Academic researchers and international enterprises can perhaps clarify whether all international expatriates are affected by the factor as organisational socialisation, and also whether the proposed model can be utilised in studying expatriates in different professional areas from those of this study. Finally, the results and their implications for research and the business world are discussed. This may assist not only Taiwanese MNCs but also global enterprises to perform their international business more efficiently in Mainland China.

  15. Sequential cloning of chromosomes

    Energy Technology Data Exchange (ETDEWEB)

    Lacks, S.A.

    1991-12-31

    A method for sequential cloning of chromosomal DNA and chromosomal DNA cloned by this method are disclosed. The method includes the selection of a target organism having a segment of chromosomal DNA to be sequentially cloned. A first DNA segment, having a first restriction enzyme site on either side. homologous to the chromosomal DNA to be sequentially cloned is isolated. A first vector product is formed by ligating the homologous segment into a suitably designed vector. The first vector product is circularly integrated into the target organism`s chromosomal DNA. The resulting integrated chromosomal DNA segment includes the homologous DNA segment at either end of the integrated vector segment. The integrated chromosomal DNA is cleaved with a second restriction enzyme and ligated to form a vector-containing plasmid, which is replicated in a host organism. The replicated plasmid is then cleaved with the first restriction enzyme. Next, a DNA segment containing the vector and a segment of DNA homologous to a distal portion of the previously isolated DNA segment is isolated. This segment is then ligated to form a plasmid which is replicated within a suitable host. This plasmid is then circularly integrated into the target chromosomal DNA. The chromosomal DNA containing the circularly integrated vector is treated with a third, retrorestriction enzyme. The cleaved DNA is ligated to give a plasmid that is used to transform a host permissive for replication of its vector. The sequential cloning process continues by repeated cycles of circular integration and excision. The excision is carried out alternately with the second and third enzymes.

    2010-03-01

    Full Text Available Orientation: Organisational climate and job satisfaction are distinct but related constructs, and both appear to influence employees’ understanding of the work environment and their level of job satisfaction.Research purpose: The objective of this study was to explore the relationship between organisational climate and job satisfaction to determine whether employees’ perceptions of the work environment influence their level of job satisfaction.Motivation for the study: Organisations are facing more challenges than ever before. These challenges are not unique to any specific organisation or industry, but affect all organisations.Organisational climate in particular is constantly challenged by changes impacting organisations today.Research design, approach and method: An organisational climate questionnaire was administered to a convenience sample of 696 employees from a population of 1453 employees working in three regions in which the organisation was operational. Confirmatory and exploratory factor analyses were used to investigate the structure of the climate model.Main findings: The revised 12-factor model (after the confirmatory factor analysis fitted the data best and the researchers therefore decided to proceed with the revised 12-factor model (11 dimensions for further analysis. A stepwise regression was conducted and nine dimensions of organisational climate were found to predict job satisfaction. The results indicated a strong positive correlation (r = 0.813, p< 0.01 between organisational climate and the dependent variable of job satisfaction.Practical implications: This study provided support for the view that line managers and human resource practitioners should be aware that different biographical groups have different needs that can influence their job satisfaction levels and different perceptions of the climate within the organisation and that this impacts on their behaviour.Contribution: The findings of this study indicated a

    X-chromosome inactivation (XCI) involves major reorganization of the X chromosome as it becomes silent and heterochromatic. During female mammalian development, XCI is triggered by upregulation of the non-coding Xist RNA from one of the two X chromosomes. Xist coats the chromosome in cis and induces silencing of almost all genes via its A-repeat region, although some genes (constitutive escapees) avoid silencing in most cell types, and others (facultative escapees) escape XCI only in specific contexts. A role for Xist in organizing the inactive X (Xi) chromosome has been proposed. Recent chromosome conformation capture approaches have revealed global loss of local structure on the Xi chromosome and formation of large mega-domains, separated by a region containing the DXZ4 macrosatellite. However, the molecular architecture of the Xi chromosome, in both the silent and expressed regions,remains unclear. Here we investigate the structure, chromatin accessibility and expression status of the mouse Xi chromosome in highly polymorphic clonal neural progenitors (NPCs) and embryonic stem cells. We demonstrate a crucial role for Xist and the DXZ4-containing boundary in shaping Xi chromosome structure using allele-specific genome-wide chromosome conformation capture (Hi-C) analysis, an assay for transposase-accessible chromatin with high throughput sequencing (ATAC-seq) and RNA sequencing. Deletion of the boundary disrupts mega-domain formation, and induction of Xist RNA initiates formation of the boundary and the loss of DNA accessibility. We also show that in NPCs, the Xi chromosome lacks active/inactive compartments and topologically associating domains (TADs), except around genes that escape XCI. Escapee gene clusters display TAD-like structures and retain DNA accessibility at promoter-proximal and CTCF-binding sites. Furthermore, altered patterns of facultative escape genes indifferent neural progenitor clones are associated with the presence of different TAD

    Before software can be designed we must know its requirements. Before requirements can be expressed we must understand the domain. So it follows, from our dogma, that we must first establish precise descriptions of domains; then, from such descriptions, “derive” at least domain and interface requirements; and from those and machine requirements design the software, or, more generally, the computing systems.

    Similarities between human and chimpanzee chromosomes are shown by chromosome banding techniques and somatic cell hybridization techniques. Cell hybrids were obtained from the chimpanzee lymphocyte LE-7, and the Chinese hamster mutant cell, Gal-2. Experiments showed that the ACPL, MDHs, and Gal-Act genes could be assigned to chimpanzee chromosome 13, and since these genes have been assigned to human chromosme 2p, it is suggested that chimpanzee chromosome 13 is homologous to human chromosome 2p.

  5. Chromosome condensation and segmentation

    International Nuclear Information System (INIS)

    Some aspects of chromosome condensation in mammalians -humans especially- were studied by means of cytogenetic techniques of chromosome banding. Two further approaches were adopted: a study of normal condensation as early as prophase, and an analysis of chromosome segmentation induced by physical (temperature and γ-rays) or chemical agents (base analogues, antibiotics, ...) in order to show out the factors liable to affect condensation. Here 'segmentation' means an abnormal chromosome condensation appearing systematically and being reproducible. The study of normal condensation was made possible by the development of a technique based on cell synchronization by thymidine and giving prophasic and prometaphasic cells. Besides, the possibility of inducing R-banding segmentations on these cells by BrdU (5-bromodeoxyuridine) allowed a much finer analysis of karyotypes. Another technique was developed using 5-ACR (5-azacytidine), it allowed to induce a segmentation similar to the one obtained using BrdU and identify heterochromatic areas rich in G-C bases pairs

    Directory of Open Access Journals (Sweden)

    Rodney Clarke

    2001-05-01

    Full Text Available The broad application of semiotic approaches to organisations has been considered by a number of information systems academics to be a necessary advance in information systems theory (see for examples Land 1985, Rzevski 1985, and Tully 1985. Along with psychology and sociology, semiotics is considered to be a foundation discipline for information systems within the IFIP WG 8.1 FRISCO Framework (Falkenberg, et al eds/ 2000. Semiotics examines the processes of production and consumption of meanings in organisations, institutions and society, and their underlying mechanisms by means of what Pap (1991, 47 refers to as a "...systematic analysis of patterns of interpretive behaviour". Although often unacknowledged, meaning is central to any definition of an information system. While the concept of meaning and meaning making is difficult to define, semiotic theory can assist by emphasising the distinctions between 'information', 'meaning', 'sense' and 'reference' for example (see Noth 1990, 92-102. Eco (1976, 8, provides a broad definition of semiotics as the study of "...all cultural processes as processes of communication". Cultural processes are interpreted to include organisational contexts and processes thereby providing a link between systems and organisations. Most applied semiotic studies start by identifying or defining one or more models of the sign as the basic unit of analysis. Signs are usually glossed as 'something that stands for something else in some capacity or another'. Depending on the model of the sign, mention may be made to an entity for whom the 'stands for' relationship applies. For a discipline often defined as the 'study of signs', there are a plethora of distinct sign models from which to choose. The reader is directed to Winfried Noth's Handbook of Semiotics for a detailed description of different sign typologies, sign models and disciplinary history (Noth 1990, 79-91. The period of modern semiotics starts at the beginning

  11. Micromechanics of human mitotic chromosomes

    International Nuclear Information System (INIS)

    Eukaryote cells dramatically reorganize their long chromosomal DNAs to facilitate their physical segregation during mitosis. The internal organization of folded mitotic chromosomes remains a basic mystery of cell biology; its understanding would likely shed light on how chromosomes are separated from one another as well as into chromosome structure between cell divisions. We report biophysical experiments on single mitotic chromosomes from human cells, where we combine micromanipulation, nano-Newton-scale force measurement and biochemical treatments to study chromosome connectivity and topology. Results are in accord with previous experiments on amphibian chromosomes and support the 'chromatin network' model of mitotic chromosome structure. Prospects for studies of chromosome-organizing proteins using siRNA expression knockdowns, as well as for differential studies of chromosomes with and without mutations associated with genetic diseases, are also discussed

    Full Text Available Abstract Background While most gamma proteobacteria have a single circular chromosome, Vibrionales have two circular chromosomes. Horizontal gene transfer is common among Vibrios, and in light of this genetic mobility, it is an open question to what extent the two chromosomes themselves share a common history since their formation. Results Single copy genes from each chromosome (142 genes from chromosome I and 42 genes from chromosome II were identified from 19 sequenced Vibrionales genomes and their phylogenetic comparison suggests consistent phylogenies for each chromosome. Additionally, study of the gene organization and phylogeny of the respective origins of replication confirmed the shared history. Conclusions Thus, while elements within the chromosomes may have experienced significant genetic mobility, the backbones share a common history. This allows conclusions based on multilocus sequence analysis (MLSA for one chromosome to be applied equally to both chromosomes.

    2006-03-01

    Full Text Available The last sixty years have seen international economic organisations maintain a position at the forefront of promoting economic growth and socioeconomic development. These organisations have not achieved as much against certain benchmarks, and several observers have accused them of being unqualified to meet the needs of the poor, and even found them guilty of something worse, such as famine and disease. Although these organisations have organisational behaviour and skills, many of their funded projects lack forcefulness to such an extent that they should only be answerable through achieving certain economic facts by way of ethics and morals. We design ethics and morals as two interconnected concepts, and the rationale that binds all economic agents to their respective obligations must be interpreted by effective courses of action dictated by economic realities.

    2015-07-01

    Full Text Available The vast research on organisational justice has focused on the organisation and the supervisor. This study aims to further this line of research by integrating two trends within organisational justice research: the overall approach to justice perceptions and the multifoci perspective of justice judgments. Specifically, this study aims to explore the effects of two additional sources of justice, coworker-focused justice and customer-focused justice, on relevant employees’ outcomes—burnout, turnover intentions, job satisfaction, and workplace deviance— while controlling the effect of organisation-focused justice and supervisor-focused justice. Given the increased importance attributed to coworkers and customers, we expect coworker-focused justice and customer-focused justice to explain incremental variance in the measured outcomes, above and beyond the effects of organisation-focused justice and supervisor-focused justice. Participants will be university students from Austria and Germany employed by service organisations. Data analysis will be conducted using structural equation modeling.

    2014-06-01

    Full Text Available The purpose of this study is to identify the correlation between the corporate social responsibility performance and the Organisational Social Capital. Inductively, through grounded theory, this paper uses secondary data to develop a theoretical model which presents the relationship between the following concepts: business codes, stakeholders, Corporate Social Performance (CSP and Organisational Social Capital (OSC. This study brings together two main areas of research, namely: Organisational Social Capital and business ethics. This represents a gap in the literature, to which this research will address. Three propositions are put forward and discussed using secondary data collection methods. The findings suggest that there is a strong correlation between the characteristics which improve the quality of organisation-stakeholders relationship and the effectiveness of implementing business codes and, therefore, the increasing Corporate Social Performance. The proposed ethical framework has, at the same time, a similar effect by incrementing Organisational Social Capital, because it shares similar features with the relation between organisation-stakeholders, business codes and CSP.

To meet these challenges, Asian leaders need to devise bold and innovative national policies for pursuing avenues for regional and global cooperation. In the similar way organisation and business in Asia will transform. This transformative whirlpool calls the Asian private sector and public sector organisations for absorption of new wisdom, values and principles in place of 20th century’s management. Overall, the capacity to respond to the changing global economic landscape through flexibility and adaptivness will carry a high premium.

    The research analyses employee engagement as a precursor to unlocking organisational performance in a public sector organisation in Zimbabwe. The organisation (herein referred to as Zim-PSO), which has been plagued by operational and people challenges, is essentially locked in underperformance, which, it is argued, could improve as employee engagement levels also improved. A sample of 50 subjects participated in the research. Data were gathered using a combination of unstructured interviews, ...

    The aim of this paper is to review the literature concerning the key factors affecting a post-merger organisation from the aspect of market orientation and organisational culture as a means of developing a conceptual framework. In the context of a large complex organisation (a Higher Education Institution), the literature indicates that there is a greater propensity for the emergence of subcultures. A number of external pressures are also found to impact upon the emergence of a market orienta...

    2009-05-01

    Full Text Available Abstract Background Given the current emphasis on networks as vehicles for innovation and change in health service delivery, the ability to conceptualise and measure organisational enablers for the social construction of knowledge merits attention. This study aimed to develop a composite tool to measure the organisational context for evidence-based practice (EBP in healthcare. Methods A structured search of the major healthcare and management databases for measurement tools from four domains: research utilisation (RU, research activity (RA, knowledge management (KM, and organisational learning (OL. Included studies were reports of the development or use of measurement tools that included organisational factors. Tools were appraised for face and content validity, plus development and testing methods. Measurement tool items were extracted, merged across the four domains, and categorised within a constructed framework describing the absorptive and receptive capacities of organisations. Results Thirty measurement tools were identified and appraised. Eighteen tools from the four domains were selected for item extraction and analysis. The constructed framework consists of seven categories relating to three core organisational attributes of vision, leadership, and a learning culture, and four stages of knowledge need, acquisition of new knowledge, knowledge sharing, and knowledge use. Measurement tools from RA or RU domains had more items relating to the categories of leadership, and acquisition of new knowledge; while tools from KM or learning organisation domains had more items relating to vision, learning culture, knowledge need, and knowledge sharing. There was equal emphasis on knowledge use in the different domains. Conclusion If the translation of evidence into knowledge is viewed as socially mediated, tools to measure the organisational context of EBP in healthcare could be enhanced by consideration of related concepts from the organisational

  19. Understanding human and organisational factors - Nuclear safety and at-risk organisations

    International Nuclear Information System (INIS)

    This book addresses human and organisational factors which are present at different moments of the lifetime of an at-risk installation (from design to dismantling). At-risk organisations are considered as firstly human systems, and the objective is then to highlight individual and collective mechanisms in these organisations. Several questions are addressed, notably the origins of at-risk behaviour, and the reasons of the repetition of errors by these organisations. A first chapter, while referring to examples, addresses the human dimension of safety: human and organisational factors as obstacles, normal accidents (Three Mile Island), accidents in high-reliability organisations (Chernobyl), identification of root causes (Tokai-mura), and social-technical approach to safety (Fukushima). By also referring to examples, the second chapter addresses how to analyse at-risk organisations: individual behaviours (case of naval and air transport accidents), team coordination (a fire, the Challenger accident), and organisational regulation (organisations forms and routines, explosion of BP Texas City, explosion of Columbia)

  20. Chromosome numbers in Bromeliaceae

    2000-01-01

    Full Text Available The present study reports chromosome numbers of 17 species of Bromeliaceae, belonging to the genera Encholirium, Bromelia, Orthophytum, Hohenbergia, Billbergia, Neoglaziovia, Aechmea, Cryptanthus and Ananas. Most species present 2n = 50, however, Bromelia laciniosa, Orthophytum burle-marxii and O. maracasense are polyploids with 2n = 150, 2n = 100 and 2n = 150, respectively, while for Cryptanthus bahianus, 2n = 34 + 1-4B. B chromosomes were observed in Bromelia plumieri and Hohenbergia aff. utriculosa. The chromosome number of all species was determined for the first time, except for Billbergia chlorosticta and Cryptanthus bahianus. Our data supports the hypothesis of a basic number of x = 25 for the Bromeliaceae family and decreasing aneuploidy in the genus Cryptanthus.

  1. Those amazing dinoflagellate chromosomes

    2003-01-01

    Dinoflagellates are a very large and diverse group of eukaryotic algae that play a major role in aquatic food webs of both fresh water and marine habitats. Moreover, the toxic members of this group pose a health threat in the form of red tides. Finally, dinoflagellates are of great evolutionary importance,because of their taxonomic position, and their unusual chromosome structure and composition. While the cytoplasm of dinoflagellates is typically eukaryotic, the nucleus is unique when compared to the nucleus of other eukaryotes. More specifically, while the chromosomes of all other eukaryotes contain histones,dinoflagellate chromosomes lack histones completely. There are no known exceptions to this observation: all dinoflagellates lack histones, and all other eukaryotes contain histones. Nevertheless, dinoflagellates remain a relatively unstudied group of eukaryotes.

  3. Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting

    2003-11-01

    Full Text Available Abstract A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+ translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote carrier. In the case of the bovine translocation, two whole chromosome probes (chromosome 5, and derived chromosome 5 were elaborated and hybridised independently on chromosomal preparations of the bull who was a carrier of the mosaic translocation. The impossibility of differentiating chromosomes 2 and der(2 from other chromosomes of the metaphases did not allow the production of painting probes for these chromosomes. For all experiments, the quality of painting was comparable to that usually observed with probes obtained from flow-sorted chromosomes. The results obtained allowed confirmation of the interpretations proposed with G-banding karyotype analyses. In the bovine case, however, the reciprocity of the translocation could not be proven. The results presented in this paper show the usefulness of the microdissection technique for characterising chromosomal rearrangements in species for which commercial probes are not available. They also confirmed that the main limiting factor of the technique is the quality of the chromosomal preparations, which does not allow the identification of target chromosomes or chromosome fragments in all cases.

    2016-01-01

    Inter-organisational communication failures during times of real-world disasters impede the collaborative response of agencies responsible for ensuring the public's health and safety. In the best of circumstances, communications across jurisdictional boundaries are ineffective. In times of crisis, when communities are grappling with the impact of a disaster, communications become critically important and more complex. Important factors for improving inter-organisational communications are critical thinking and problem-solving skills; inter-organisational relationships; as well as strategic, tactical and operational communications. Improving communication, critical thinking, problem-solving and decision-making requires a review of leadership skills. This discussion begins with an analysis of the existing disaster management research and moves to an examination of the importance of inter-organisational working relationships. Before a successful resolution of a disaster by multiple levels of first responders, the group of organisations must have a foundation of trust, collegiality, flexibility, expertise, openness, relational networking and effective communications. Leaders must also be prepared to improve leadership skills through continual development in each of these foundational areas. PMID:27318289

  16. Chromatin domain boundaries: insulators and beyond

    Institute of Scientific and Technical Information of China (English)

    Gong Hong WEI; De Pei LIU; Chih Chuan LIANG

    2005-01-01

    The eukaryotic genome is organized into functionally and structurally distinct domains, representing regulatory units for gene expression and chromosome behavior. DNA sequences that mark the border between adjacent domains are the insulators or boundary elements, which are required in maintenance of the function of different domains. Some insulators need others enable to play insulation activity. Chromatin domains are defined by distinct sets of post-translationally modified histones. Recent studies show that these histone modifications are also involved in establishment of sharp chromatin boundaries in order to prevent the spreading of distinct domains. Additionally, in some loci, the high-order chromatin structures for long-range looping interactions also have boundary activities, suggesting a correlation between insulators and chromatin loop domains. In this review, we will discuss recent progress in the field of chromatin domain boundaries.

  17. The mediating effect of knowledge sharing between organisational culture and turnover intentions of professional nurses

    Directory of Open Access Journals (Sweden)

    Everd J. Jacobs

    2011-03-01

    Full Text Available Professional nurses routinely use highly developed domain knowledge in combination with experiential knowledge to deliver quality care. However, this knowledge is often lost to employers as the migration of professional nurses from the developing countries to the developed world has become a global problem. The objective of this study therefore was to determine the relationships between organisational culture, knowledge sharing and turnover intentions and thereafter to propose knowledge sharing as a mediating variable in this relationship in order to suggest a retention strategy. A cross-sectional field survey design with questionnaires was used on a sample of professional nurses (N = 530 in private and provincial hospitals in South Africa. The tri-variate procedure of Baron and Kenny for mediation testing was adopted. The results indicated that a positive correlation exists between organisational culture and knowledge sharing, but a significant negative correlation between organisational culture and turnover intentions, as well as between knowledge sharing and turnover intentions. Finally, the results indicated that knowledge sharing mediates the relationship between organisational culture and turnover intentions, although with a small effect size.The findings suggest that turnover intentions of nurses can be actively managed through contextual variables such as organisational culture and opportunities for knowledge sharing.

    1997-04-01

    Modern concepts of the self-assembly of amphiphiles are considered on the example of self-organising structures of the natural lecithin. Binary, ternary and multicomponent systems are discussed. A considerable part of the review is devoted to the peculiarities of self-organisation of this phospholipid in non-aqueous media and to the role of polar inorganic solvents. Virtually all of the structures formed by lecithin are examined: micelles, swollen micelles, microemulsions, emulsions, organogels, vesicles (liposomes), and lyotropic liquid crystals. In each specific case, attention is drawn to the dependence of self-assembly at the macroscopic level on interactions at the molecular level, shape of molecules, and their solvation and packing at the interface. The self-organising lecithin structures formed in the interfacial area of immiscible liquids in the course of unrestricted adsorption from the bulk of non-aqueous solution are considered. The bibliography includes 282 references.

    Directory of Open Access Journals (Sweden)

    Joyce Kirk

    1999-01-01

    Full Text Available The work of managers in small and medium-sized enterprises is very information-intensive and the environment in which it is done is very information rich. But are managers able to exploit the wealth of information which surrounds them? And how can information be managed in organisations so that its potential for improving business performance and enhancing the competitiveness of these enterprises can be realised? Answers to these questions lie in clarifying the context of the practice of information management by exploring aspects of organisations and managerial work and in exploring the nature of information at the level of the organisation and the individual manager. From these answers it is possible to suggest some guidelines for managing the integration of business strategy and information, the adoption of a broadly-based definition of information and the development of information capabilities.

  4. Carbon footprinting. An introduction for organisations

    International Nuclear Information System (INIS)

    To some degree or other, every person and every organisation, either directly or indirectly, is responsible for producing carbon dioxide gas which finds its way into the atmosphere and therefore contributes to the greenhouse effect. The amount of carbon dioxide produced by a person, an organisation, a company, an industry, an event, or even a population can be quantified in what is now described as a carbon footprint. Gases other than carbon dioxide are also released to the atmosphere through man's activities and these can also be evaluated in terms of the carbon footprint. This document explains the meaning of the expression 'carbon footprint' and aims to assist businesses and organisations to determine collective and individual carbon footprints

    2001-01-01

    Effective collaboration has always been one of the foundations of CERN's success. An essential ingredient for collaboration is communication and a new body EIROFORUM has just held its first meeting in Brussels with the aim of developing greater cross fertilization of ideas and projects. Seven organisations, CERN, EMBL (molecular biology), ESA (space activities), ESO (astronomy and astrophysics), ESRF (synchrotron radiation), ILL (neutron source) and EFDA (fusion) are currently members of EIROFORUM. Common interest between the organisations in computational grid development, materials science, instrumentation, public outreach and technology transfer has made EIROFRUM an essential group for maximising these European research organisations' resources. Increasing involvement in the Sixth Framework Programme, Europe's research guidelines for the next four years, is also one of the goals of the group. CERN takes over the chair of EIROFORUM in July 2001 and the next meeting will be held on site on 24 October .

  10. Chromosomes, cancer and radiosensitivity

    Energy Technology Data Exchange (ETDEWEB)

    Samouhos, E.

    1983-08-01

    Some specific chromosomal abnormalities are associated with certain cancers. The earliest description of such a specific association is the one of the Philadelphia chromosome and myelogenous leukemia (1960). Other congenital karyotype abnormalities are associated with specific cancers. Examples of these are Down's syndrome with leukemia and Klinefelter's syndrome with male breast cancer. Genetic diseases of increased chromosome breakage, or of defective chromosome repair, are associated with greatly increased cancer incidence. Three such diseases have been recognized: 1) Fanconi's anemia, associated with leukemias and lymphomas, 2) Bloom's syndrome, associated with acute leukemias and lymphosarcoma, and 3) ataxia telangiectasia, associated with Hodgkin's disease, leukemia, and lymphosarcomas. Ten percent of individuals with ataxia telangiectasia will develop one of these neoplasms. Individuals with certain of these syndromes display an unusually high radiosensitivity. Radiation therapy for cancers has been fatal in patients who received as low as 3000 rad. This remarkable radiosensitivity has been quantitated in cell cultures from such cases. Evidence suggests that the apparent sensitivity may reflect subnormal ability to repair radiation damage. The rapid proliferation of information in this field stems from the interdigitation of many disciplines and specialties, including cytogenetics, cell biology, molecular biology, epidemiology, radiobiology, and several others. This paper is intended for clinicians; it presents a structured analytic scheme for correlating and classifying this multidisciplinary information as it becomes available.

Radiation therapy for cancers has been fatal in patients who received as low as 3000 rad. This remarkable radiosensitivity has been quantitated in cell cultures from such cases. Evidence suggests that the apparent sensitivity may reflect subnormal ability to repair radiation damage. The rapid proliferation of information in this field stems from the interdigitation of many disciplines and specialties, including cytogenetics, cell biology, molecular biology, epidemiology, radiobiology, and several others. This paper is intended for clinicians; it presents a structured analytic scheme for correlating and classifying this multidisciplinary information as it becomes available

  13. Mission creep or responding to wider security needs? The evolving role of mine action organisations in Armed Violence Reduction

    Directory of Open Access Journals (Sweden)

    Sharmala Naidoo

    2013-04-01

    Full Text Available Since the late 1980s, mine action organisations have focused their efforts on reducing the social, economic and environmental impacts of anti-personnel mines and other explosive remnants of war (ERW through a broad range of activities, including survey, clearance, mine risk education (MRE, victim assistance, stockpile destruction and advocacy. In recent years, an increasing number of mine action organisations are using their mine action technical expertise and their capacities to operate in difficult environments to reduce armed violence and promote public safety. Several organisations now have armed violence reduction (AVR-related policies, programmes and staff in place. Some may argue that this shift towards AVR is a diversion from the core mandate of mine action organisations. But does this represent a loss of focus and thereby ‘mission creep’ on the part of these organisations? This practice note examines the factors underlying the evolving role of mine action organisations, discusses how these new programmes are contributing to the wider domain of AVR and explores whether these new programmes have resulted in a loss of organisational focus.

  14. Telomere dysfunction and chromosome instability

    The ends of chromosomes are composed of a short repeat sequence and associated proteins that together form a cap, called a telomere, that keeps the ends from appearing as double-strand breaks (DSBs) and prevents chromosome fusion. The loss of telomeric repeat sequences or deficiencies in telomeric proteins can result in chromosome fusion and lead to chromosome instability. The similarity between chromosome rearrangements resulting from telomere loss and those found in cancer cells implicates telomere loss as an important mechanism for the chromosome instability contributing to human cancer. Telomere loss in cancer cells can occur through gradual shortening due to insufficient telomerase, the protein that maintains telomeres. However, cancer cells often have a high rate of spontaneous telomere loss despite the expression of telomerase, which has been proposed to result from a combination of oncogene-mediated replication stress and a deficiency in DSB repair in telomeric regions. Chromosome fusion in mammalian cells primarily involves nonhomologous end joining (NHEJ), which is the major form of DSB repair. Chromosome fusion initiates chromosome instability involving breakage-fusion-bridge (B/F/B) cycles, in which dicentric chromosomes form bridges and break as the cell attempts to divide, repeating the process in subsequent cell cycles. Fusion between sister chromatids results in large inverted repeats on the end of the chromosome, which amplify further following additional B/F/B cycles. B/F/B cycles continue until the chromosome acquires a new telomere, most often by translocation of the end of another chromosome. The instability is not confined to a chromosome that loses its telomere, because the instability is transferred to the chromosome donating a translocation. Moreover, the amplified regions are unstable and form extrachromosomal DNA that can reintegrate at new locations. Knowledge concerning the factors promoting telomere loss and its consequences is

  16. Abandonment: Technological, organisational and environmental challenges

    International Nuclear Information System (INIS)

    The paper deals with the abandonment of offshore wells. Decommissioning of offshore installations is a complex multi-disciplined issue, which raises a number of technical, organisational and environmental challenges. The success of a planned decommissioning operation depends on the development of a clear understanding of the complex blend of drivers which control the decommissioning process and their inter-relationship. Due to the complexity of the inter-relationship between the primary drivers one cannot separate the technological, organisational and environmental issues raised by the decommissioning of offshore installations. The optimal solution will be a compromise between all the decommissioning drivers mentioned in this paper. 5 figs., 3 tabs

  4. Rise, fall and resurrection of chromosome territories: a historical perspective. Part I. The rise of chromosome territories

    Directory of Open Access Journals (Sweden)

    T Cremer

    2009-06-01

    Full Text Available It is now generally accepted that chromosomes in the cell nucleus are organized in distinct domains, first called chromosome territories in 1909 by the great cytologist Theodor Boveri. Yet, even today chromosomes have remained enigmatic individuals, whose structures, arrangements and functions in cycling and post-mitotic cells still need to be explored in full detail. Whereas numerous recent reviews describe present evidence for a dynamic architecture of chromosome territories and discuss the potential significance within the functional compartmentalization of the nucleus, a comprehensive historical account of this important concept of nuclear organization was lacking so far. Here, we describe the early rise of chromosome territories within the context of the discovery of chromosomes and their fundamental role in heredity, covering a period from the 1870th to the early 20th century (part I, this volume. In part II (next volume we review the abandonment of the chromosome territory concept during the 1950th to 1980th and the compelling evidence, which led to its resurrection during the 1970th to 1980th.

    2009-11-01

    An effective approach to study the chromosome organization in genomes of plants with small chromosomes and/or with low-informative C-banding patterns was developed in the course of investigation of the karyotypes of cotton plant, camomile, flax, and pea. To increase the resolving power of chromosome analysis, methods were worked out for revealing early replication patterns on chromosomes and for artificial impairment of mitotic chromosome condensation with the use of a DNA intercalator, 9-aminoacridine (9-AMA). To estimate polymorphism of the patterns of C-banding of small chromosomes on preparations obtained with the use of 9-AMA, it is necessary to choose a length interval that must not exceed three average sizes of metaphase chromosomes without the intercalator. The use of 9-AMA increases the resolution of differential C- and OR-banding and the precision of physical chromosome mapping by the FISH method. Of particular importance in studying small chromosomes is optimization of the computer-aided methods used to obtain and process chromosome images. The complex approach developed for analysis of the chromosome organization in plant genomes was used to study the karyotypes of 24 species of the genus Linum L. It permitted their chromosomes to be identified for the first time, and, in addition, B chromosomes were discovered and studied in the karyotypes of the species of the section Syllinum. By similarity of the karyotypes, the studied flax species were distributed in eight groups in agreement with the clusterization of these species according to the results of RAPD analysis performed in parallel. Systematic positions and phylogenetic relationships of the studied flax species were verified. Out results can serve as an important argument in favour of the proposal to develop a special program for sequencing the genome of cultivated flax (L. usitatissimum L.), which is a major representative of small-chromosome species.

    Full Text Available New technologies have led to a new information and knowledge based economy. In this context, technology has changed the work environment, where organisations have become increasingly complex and competitive. Namely, the technologically induced a “virtual” environment has resulted in the adoption of new organisational structures and work skills and practices. On the one hand, the workplace increasingly requires employee to work in teams,collaborating across companies, communities, and continents. These changes and the new organisational structures have also made an impact on role of managers and their management styles, on the other hand. In line with this, there a very rich collection of thinking and empirical research findings on the subject. The goal of our research was to recognize the importance of certain factors in motivating employees in organisations by managers . The other purpose was to investigate the job related motivation factors among senior and junior employees as well as explore issues in the workplace that may affect work demoralization. Furthemore, we explored the relationship between employees motivation and their competences.We also contributed to the topic in our research project-book with the new model of competency. Furthemore, we expect that our methodology will be implemented in practice. However, it should be also a good basis for further improvements in this area.

  9. Evaluating the internalisation of core values at a South African public service organisation

    Directory of Open Access Journals (Sweden)

    Susanna M. O’Neil

    2012-09-01

    Full Text Available Orientation: Fully entrenched and internalised organisational values have proved a competitive advantage for many leading organisations. The benefits range from higher profit margins to the improvement of employees’ commitment and ethical performance. Nevertheless, the process of value shaping is often no more than a management goal. It is rarely truly internalised by the whole organisation.Research purpose: This article presents an effort to describe a value internalisation effort within a South African public service organisation as well as the results of a subsequent evaluation to ascertain to what extent those efforts actually led to internalisation throughout the organisation. A set of actions and practices were implemented within the public service organisation; the intent was that they should enhance value internalisation in the organisation. A long-term strategy of value internalisation was followed that focussed mainly on the clear articulation and communication of the values through different communication mediums and platforms, such as road shows and branded value material hand-outs, as well as through extensive value internalisation training.Motivation for the study: Documentation of value internalisation processes and its evaluation, especially in South African public service organisations is extremely rare. To ensure that public service organisations do not repeat the same mistakes in their value internalisation practices and implementation processes, proper documentation of these processes in the public and research domains are needed. The need for the evaluation of value internalisation programmes should also be propagated as in many instances, programmes are implemented, but the subsequent success thereof is never evaluated.Research design, approach and method: A survey questionnaire consisting of a 5-point rating scale was developed to measure the extent of value internalisation after the implementation of long

  10. Quantifying the effects of resolution on convective organisation in cloud-system resolving simulations of West Africa.

    White, Bethan; Stier, Philip; Birch, Cathryn

    2016-04-01

    Convection transports moisture, momentum, heat and aerosols through the troposphere, and so the variability of convection is a major driver of global weather and climate. Convection in the tropics is organised across a wide range of spatiotemporal scales, from the few kilometres and hours associated with individual cloud systems, through the mesoscale of squall lines and cloud clusters, to the synoptic scale of tropical cyclones. Global and limited area models often fail to represent many of these scales of organisation, and the interaction between the scales remains poorly understood. In this work we devise a new metric to quantify the degree of convective organisation. We apply this metric to data from simulations of the West African Monsoon region from the CASCADE project, where simulations were performed using the Met Office Unified Model at 12 km horizontal grid length with parameterised convection, and at 12, 4 and 1.5 km horizontal grid lengths with permitted convection. This allows us to perform quantitative analysis of convective organisation across model configurations that experience the same large-scale state and differ only in horizontal grid length and representation of deep convection. We show that our analysis technique can be usefully applied to high-resolution, cloud-system resolving, large-domain simulations of tropical convection. We use our technique to quantify the effects of horizontal grid length and of convective parameterisation on the degree of organisation in the simulated convection, and investigate the spatiotemporal variability of the convective organisation in the different model configurations. We then determine relationships between the degree of convective organisation and precipitation. Further, we compare our results against equivalent parameters derived from satellite data to identify how well each of the model configurations performs against observations. Through the use of this new metric, this work provides a quantitative

Travel support for American participants was provided by the Department of Energy. The goals of this workshop were to produce genetic, physical and integrated maps of chromosome 19, to identify inconsistencies and gaps, and to discuss and exchange resources and techniques available for the completion of these maps. The second day of the meeting was largely devoted to region or disease specific efforts. In particular, the meeting served as a platform for assessing and discussing the recent progress made into the molecular elucidation of myotonic dystrophy.

  18. The Concept of Embodied Knowledge for Understanding Organisational Knowledge Creation

    Science.gov (United States)

    Matsudaira, Yoshito; Fujinami, Tsutomu

    Our goal in this paper is to understand, in the light of intuition and emotion, the problem-finding and value judgments by organisational members that are part of organisational knowledge creation. In doing so, we emphasise the importance of embodied knowledge of organisations as an explanatory concept. We propose ways of approaching intuition and sense of value as these are posited as objects of research. Approaches from the first, second, and third-person viewpoints result in a deeper grasp of embodied knowledge of organisations. Important in organisational knowledge creation is embodied knowledge of organisations, which has a bearing on problem-finding before any problem-solving or decision making takes place, and on value judgments about the importance of problems that have been found. This article proposes the concept of embodied knowledge, and, by introducing it, gives a profound understanding of that facet of organisational knowledge creation characterised by tacit knowledge held by organisational individuals.

  19. Chromosomal localization of the human and mouse hyaluronan synthase genes

    Energy Technology Data Exchange (ETDEWEB)

    Spicer, A.P.; McDonald, J.A. [Mayo Clinic Scottsdale, AZ (United States); Seldin, M.F. [Univ. of California Davis, CA (United States)] [and others

    1997-05-01

    We have recently identified a new vertebrate gene family encoding putative hyaluronan (HA) synthases. Three highly conserved related genes have been identified, designated HAS1, HAS2, and HAS3 in humans and Has1, Has2, and Has3 in the mouse. All three genes encode predicted plasma membrane proteins with multiple transmembrane domains and approximately 25% amino acid sequence identity to the Streptococcus pyogenes HA synthase, HasA. Furthermore, expression of any one HAS gene in transfected mammalian cells leads to high levels of HA biosynthesis. We now report the chromosomal localization of the three HAS genes in human and in mouse. The genes localized to three different positions within both the human and the mouse genomes. HAS1 was localized to the human chromosome 19q13.3-q13.4 boundary and Has1 to mouse Chr 17. HAS2 was localized to human chromosome 8q24.12 and Has2 to mouse Chr 15. HAS3 was localized to human chromosome 16q22.1 and Has3 to mouse Chr 8. The map position for HAS1 reinforces the recently reported relationship between a small region of human chromosome 19q and proximal mouse chromosome 17. HAS2 mapped outside the predicted critical region delineated for the Langer-Giedion syndrome and can thus be excluded as a candidate gene for this genetic syndrome. 33 refs., 2 figs.

    Esbjerg, Lars

    How do retailers decide what products to buy? Previous answers to this question have tended to focus on the decisions being made, typically investigating what criteria retail buyers use to choose between products and suppliers (Hansen & Skytte 1998). However, as the decisions made by retail buyers...... have been treated as if they were more or less discrete events in previous studies, little is known about the process leading up to a decision being made. Furthermore, scant attention has been paid to the contexts within which retailer buying behaviour occurs. In contrast, this project views retailer...... buying behaviour as an ongoing organisational sensemaking process embedded in, at least, social, organisational, competitive and societal contexts. The aim is to gain an understanding of how and why retail buyers make certain decisions rather than simply focusing on what they decide....

  8. Organisation development possibilities of Croatian electricity markets

    International Nuclear Information System (INIS)

    Organisational development of the European Union members' power sector is defined by the obligatory legislative document Directives 92/96 EC, 19.12.1996. The development goal is a natural monopoly decrease and introduction of competition, having in mind environmental protection which will enable sustainable development of each member. This would provide the European economy to become globally more competitive and to protect macro economic stability more efficiently. The EU members are allowed to make their own decisions regarding the mode of implementation they will use to establish the organisation of electricity market. Non-members of EU are also involved in defining future changes. Developed non-members are more efficient in that process and promptly follow all changes. Transition countries, among them also Croatia, are trying to adjust to such demands, with different success. The aim of this paper is analyse the current Croatian power system and the possibilities if its modernisation. (author)

    Rocha, Luis Enrique Correa; 10.1209/0295-5075/91/28005

    2010-01-01

    Interaction between consumers and companies can create conflict. When a consensus is unreachable there are legal authorities to resolve the case. This letter is a study of data from the Brazilian Department of Justice from which we build a bipartite network of categories of complaints linked to the companies receiving those complaints. We find the complaint categories organised in an hierarchical way where companies only get complaints of lower degree if they already got complaints of higher degree. The fraction of resolved complaints for a company appears to be nearly independent on the equity of the company but is positively correlated with the total number of complaints received. We construct feature vectors based on the edge-weight - the weight of an edge represents the times complaints of a category have been filed against that company - and use these vectors to study the similarity between the categories of complaints. From this analysis, we obtain trees mapping the hierarchical organisation of the comp...

  12. Organisational culture: A contemporary management perspective

    Directory of Open Access Journals (Sweden)

    Richard Weeks

    2010-12-01

    Full Text Available Purpose: The purpose of this paper is to analyse the concept "organisational culture from a traditional and a more contemporary management perspective. Problem investigated: The concept organizational culture has assumed a very prominent place within the management literature and has been analysed from diverse multidisciplinary perspectives. Central to the importance attributed to the concept is the fact that it acts as a perceptual and behavioural determinant, which implies that it will have a significant impact on all human related institutional activities and thus the interest in the concept and its management. Researchers and management practitioners have come to assume that while the concept is difficult to manage in practice, it is possible to determine the prevailing culture of an institution, identify what is termed to be a desired culture for an institution and then analyse the cultural gap that exists. Based on the analysis conducted, it is further frequently assumed that the transition from the prevailing to a desired culture can be managed. A more contemporary management perspective, based on complexity theory, would appear to challenge the assumption of being able to actively manage the organisation's culture transformation process to ensure that a desired culture is manifest within the institution. The traditional and more contemporary approaches for dealing with the concept "organisational culture" are the focus of discussion and analysis in this paper. Methodology: A multidisciplinary literature review and analysis is undertaken to gain an insight of traditional and contemporary management theory and practice, as it relates to the concept "organisational culture" and its management. Findings: An important conclusion drawn from the study is that traditional paradigms of organisational culture management, that evolved within a more mechanistic manufacturing economy, is no longer effective for dealing with the unpredictable and

  17. Molecular fundamentals of chromosomal mutagenesis

    International Nuclear Information System (INIS)

    Precise quantitative correlation between the yield of chromosome structure damages and the yield of DNA damages is shown when comparing data on molecular and cytogenetic investigations carried out in cultural Mammalia cells. As the chromosome structure damage is to be connected with the damage of its carcass structure, then it is natural that DNA damage in loop regions is not to affect considerably the structure, while DNA damage lying on the loop base and connected with the chromosome carcass is to play a determining role in chromosomal mutagenesis. This DNA constitutes 1-2% from the total quantity of nuclear DNA. If one accepts that damages of these regions of DNA are ''hot'' points of chromosomal mutagenesis, then it becomes clear why 1-2% of preparation damages in a cell are realized in chromosome structural damages

    Carbamoyl phosphate synthetase II encodes the first enzymic step of de novo pyrimidine biosynthesis. Carbamoyl phosphate synthetase II is essential for Toxoplasma gondii replication and virulence. In this study, we characterised the primary structure of a 28kb gene encoding Toxoplasma gondii carbamoyl phosphate synthetase II. The carbamoyl phosphate synthetase II gene was interrupted by 36 introns. The predicted protein encoded by the 37 carbamoyl phosphate synthetase II exons was a 1,687 amino acid polypeptide with an N-terminal glutamine amidotransferase domain fused with C-terminal carbamoyl phosphate synthetase domains. This bifunctional organisation of carbamoyl phosphate synthetase II is unique, so far, to protozoan parasites from the phylum Apicomplexa (Plasmodium, Babesia, Toxoplasma) or zoomastigina (Trypanosoma, Leishmania). Apicomplexan parasites possessed the largest carbamoyl phosphate synthetase II enzymes due to insertions in the glutamine amidotransferase and carbamoyl phosphate synthetase domains that were not present in the corresponding gene segments from bacteria, plants, fungi and mammals. The C-terminal allosteric regulatory domain, the carbamoyl phosphate synthetase linker domain and the oligomerisation domain were also distinct from the corresponding domains in other species. The novel C-terminal regulatory domain may explain the lack of activation of Toxoplasma gondii carbamoyl phosphate synthetase II by the allosteric effector 5-phosphoribosyl 1-pyrophosphate. Toxoplasma gondii growth in vitro was markedly inhibited by the glutamine antagonist acivicin, an inhibitor of glutamine amidotransferase activity typically associated with carbamoyl phosphate synthetase II, guanosine monophosphate synthetase, or CTP synthetase.

  20. Conceptual and Theoretical Frameworks for Organised Violence

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available The possibility of violence is ubiquitous in human social relations; its forms are manifold and its causes complex. Different types of violence are inter- related, but in complex ways, and they are studied within a wide range of disciplines, so that a general theory, while possible, is difficult to achieve. This paper, acknowledging that violence can negate power and that all forms of social power can entail violence, proceeds on the assumption that the organisation of violence is a particular source of social power. It therefore explores the general relationships of violence to power, the significance of war as the archetype of organised violence, the relationships of other types (revolution, terrorism, genocide to war, and the significance of civilian-combatant stratification for the understanding of all types of organised violence. It then discusses the problems of applying conceptual types in analysis and the necessity of a historical framework for theorising violence. The paper concludes by offering such a framework in the transition from industrialised total war to global surveillance war.

  1. Organisational challenges of maintenance work at NPPs

    International Nuclear Information System (INIS)

    The proper working of the machinery is critical to NPP safety and productivity. Because maintenance routines and plant modifications are the activities that intervene most with the machinery, they are also the dominant sources of faults. Most of the human factor studies have relied on this fact. Due to the diversity, the temporal and spatial separation of the maintenance tasks, and the numerous competence requirements, focusing on a single task, special situation or a single psychological problem can only partially explain the requirements of maintenance work and the organisational challenges of effective maintenance. We have applied a cultural approach to maintenance work. Our aim has been to model the maintenance task and its psychological requirements and to characterise the features of organisational cultures in three NPP maintenance units. Results imply similarities and differences in the cultures and in the emphasis on the maintenance task. Maintenance activities have been under various restructuring initiatives. These changes have been experienced as stressful among the personnel. The effect of changes on the reliability of maintenance should be considered. A challenge for maintenance is to be able to build organisational structures and practices that would facilitate the fulfilment of the psychological work characteristics. (orig.)

  2. Self-organisation and motion in plants

    Lenau, T. A.; Hesselberg, T.

    2014-03-01

    Self-organisation appeals to humans because difficult and repeated actions can be avoided through automation via bottom-up nonhierarchical processes. This is in contrast to the top-level controlled action strategy normally applied in automated products and in manufacturing. There are many situations where it is required that objects perform an action dependent on external stimuli. An example is automatic window blinds that open or closes in response to sunlight level. However, simpler and more robust designs could be made using the self-organising principles for movement found in many plants. Plants move to adapt to external conditions, e.g. sun-flower buds tracking the sun, touch-me-not Mimosa and Venus fly trap responding to mechanical stimuli by closing leaves to protect them and capture insects respectively. This paper describes 3 of the basic biomimetic principles used by plants to track the sun; i) light causing an inhibiting effect on the illuminated side causing it to bend, ii) light inducing a signal from the illuminated side that causes an action on the darker side and iii) light illuminating a number of sensing plates pointing upwards at an angle activate an expansion on the same side. A concept for mimicking the second principle is presented. It is a very simple and possible reliable self-organising structure that aligns a plate perpendicular to the source of illumination.

    Full Text Available (Editorial preface. The publication is presented in order to remind us of one of dramatic pages of the history of genetics. It re-opens for the contemporary reader a comprehensive work marking the priority change from plant cytogenetics to animal cytogenetics led by wide population studies which were conducted on Drosophila polytene chromosomes. The year of the publication (1937 became the point of irretrievable branching between the directions of Old World and New World genetics connected with the problems of chromosome variability and its significance for the evolution of the species. The famous book of T. Dobzhansky (1937 was published by Columbia University in the US under the title “Genetics and the origin of species”, and in the shadow of this American ‘skybuilding’ all other works grew dim. It is remarkable that both Dobzhansky and Dubinin come to similar conclusions about the role of chromosomes in speciation. This is not surprising given that they both might be considered as representatives of the Russian genetic school, by their birth and education. Interestingly, Dobzhansky had never referred to the full paper of Dubinin et al. (1937, though a previous short communication in Nature (1936 was included together with all former papers on the related subject. In full, the volume of the original publication printed in the Biological Journal in Moscow comprised 47 pages, in that number 41 pages of the Russian text accompanied by 16 Figs, a table and reference list, and, above all, 6 pages of the English summary. This final part in English is now reproduced in the authors’ version with the only addition being the reference list in the originally printed form.

    One of the most difficult problems in modern genomics is the assembly of full-length chromosomes using next generation sequencing (NGS) data. To address this problem, we developed “reference-assisted chromosome assembly” (RACA), an algorithm to reliably order and orient sequence scaffolds generated by NGS and assemblers into longer chromosomal fragments using comparative genome information and paired-end reads. Evaluation of results using simulated and real genome assemblies indicates that ou...

    Full Text Available Abstract Background Premature ovarian failure (POF is a secondary hypergonadotrophic amenorrhea occurring before the age of 40 and affecting 1-3% of females. Chromosome anomalies account for 6-8% of POF cases, but only few cases are associated with translocations involving X and Y chromosomes. This study shows the cytogenetic and molecular analysis of a POF patient came to our attention as she developed a left ovary choriocarcinoma at the age of 10 and at 14 years of age she presented secondary amenorrhea with elevated levels of gonadotropins. Results Breakpoint position on X and Y chromosomes was investigated using Fluorescent In Situ Hybridisation (FISH with a panel of specific BAC probes, microsatellite analysis and evaluation of copy number changes and loss of heterozigosity by Affymetrix® GeneChip platform (Santa Clara, CA, USA. Patient's karyotype resulted 46, X, der(Yt(X;Y(q13.1;q11.223. X inactivation study was assessed by RBA banding and showed preferential inactivation of derivative chromosome. The reciprocal spatial disposition of sexual chromosome territories was investigated using whole chromosome painting and centromeres probes: patient's results didn't show a significant difference in comparison to normal controls. Conclusion The peculiar clinical case come to our attention highlighted the complexity of POF aetiology and of the translocation event, even if our results seem to exclude any effect on nuclear organisation. POF phenotype could be partially explained by skewed X chromosome inactivation that influences gene expression.

  6. Fluorescence in situ hybridisation in chromosome aberration detection in subjects occupationally exposed to ionising radiation

    International Nuclear Information System (INIS)

    For more than two decades, chromosomal aberration analysis has been used to detect structural chromosomal aberrations as sensitive biodosimeters of occupational exposure to ionising radiation. Its use is also recommended by the World Health Organisation. Changes in chromosome structure detected by that method are considered to be early biomarkers of a possible malignant disease. Aberrations detected by the method are unstable and can be found in the lymphocytes of irradiated personnel only within a limited time after exposure. To detect stable chromosomal aberrations, which persist after exposure, multicolour fluorescent in situ hybridisation has to be used. Using DNA probes labelled with different fluorochromes, it dyes each pair of chromosomes with different colour. Due to the dynamic of unstable aberration formation, chromosomal aberration analysis is more suitable in genome damage assessment of recent exposures. On the other hand, fluorescence in situ hybridisation gives the information on chromosome instability caused by long-term occupational exposure to ionising radiation. Considering the high costs of fluorescence in situ hybridisation and the uncertainty of the result, it should be used in biodosimetry only when it is absolutely necessary.(author)

    2004-10-01

    Full Text Available The identity concept has been around in the form of “corporate identity" for some time, but its appearance as “organisation identity" is more recent. Emerging theory and initial empirical research suggest that an identity approach and “identity interventions" in particular, offer promising avenues to the organisation development practitioner for enhancing organisational focus, building resilience in the face of major change, and improving performance. Identity interventions in and of themselves, but also employed as pre-change interventions, build organisational capacity that would stave off premature organisational “death" and extend the organisation’s life expectancy. Opsomming Die identiteitskonsep is in die vorm van korporatiewe identiteit reeds ’n geruime tyd in omgang, maar die verskyning daarvan as “organisasie-identiteit? is meer onlangs.

    Researchers presented results of ongoing research to the X-chromosome workshop of the Fifth World Congress on Psychiatric Genetics, covering a wide range of disorders: X-linked infantile spasms; a complex phenotype associated with deletions of Xp11; male homosexuality; degree of handedness; bipolar affective disorder; schizophrenia; childhood onset psychosis; and autism. This report summarizes the presentations, as well as reviewing previous studies. The focus of this report is on linkage findings for schizophrenia and bipolar disorder from a number of groups. For schizophrenia, low positive lod scores were obtained for markers DXS991 and DXS993 from two studies, although the sharing of alleles was greatest from brother-brother pairs in one study, and sister-sister in the other. Data from the Irish schizophrenia study was also submitted, with no strong evidence for linkage on the X chromosome. For bipolar disease, following the report of a Finnish family linked to Xq24-q27, the Columbia group reported some positive results for this region from 57 families, however, another group found no evidence for linkage to this region. Of interest, is the clustering of low positive linkage results that point to regions for possible further study. PMID:9686435

    Species of the legume genera Lathyrus and Pisum possess chromosomes that exhibit a unique structure of their centromeric regions, which is clearly apparent during metaphase by the formation of extended primary constrictions which span up to a third of the length of the chromosome. In addition, these species express two different variants of the CenH3 protein which are co-localized in multiple domains along the poleward surface of the primary constrictions. Here, we show that the constrictions represent a distinct type of chromatin differing from the chromosome arms. In metaphase, histone phosphorylation patterns including H3S10ph, H3S28ph, and H3T3ph were observed along the entire constriction, in a way similar to holocentric chromosomes. On the other hand, distribution of phosphorylated H2AT120 was different from that previously reported from either, holocentric and monocentric chromosomes, occurring at chromatin surrounding but not overlapping CenH3 domains. Since some of these phosphorylations play a role in chromatid cohesion, it can be assumed that they facilitate correct chromosome segregation by ensuring that multiple separate CenH3 domains present on the same chromatid are oriented toward the same pole. The constrictions also displayed distinct patterns of histone methylation marks, being enriched in H3K9me2 and depleted in H3K4me3 and H3K27me2 compared to the chromosome arms. Super-resolution fluorescence microscopy revealed that although both CenH3 protein variants are present in all CenH3 domains detected on metaphase chromosomes, they are only partially co-localized while there are chromatin subdomains which are mostly made of only one CenH3 variant. Taken together, these data revealed specific features of extended primary constrictions of Lathyrus and Pisum and support the idea that they may represent an intermediate stage between monocentric and holocentric chromosomes.

  17. Learning to Adapt. Organisational Adaptation to Climate Change Impacts

    International Nuclear Information System (INIS)

    Analysis of human adaptation to climate change should be based on realistic models of adaptive behaviour at the level of organisations and individuals. The paper sets out a framework for analysing adaptation to the direct and indirect impacts of climate change in business organisations with new evidence presented from empirical research into adaptation in nine case-study companies. It argues that adaptation to climate change has many similarities with processes of organisational learning. The paper suggests that business organisations face a number of obstacles in learning how to adapt to climate change impacts, especially in relation to the weakness and ambiguity of signals about climate change and the uncertainty about benefits flowing from adaptation measures. Organisations rarely adapt 'autonomously', since their adaptive behaviour is influenced by policy and market conditions, and draws on resources external to the organisation. The paper identifies four adaptation strategies that pattern organisational adaptive behaviour

    Classical neocentromeres, proven mainly in Poaceae species, cause meiotic drive in higher plants. Here I present data indicating that the morphological stretching of a chromatin domain at the long arm of Aegilops markgrafii chromosome E during meiosis is not due to a supposed neocentric activity. The stretching is visible at the alien univalent in metaphase I and anaphase I pollen mother cells of Triticum aestivum--Ae. markgrafii monosomic addition line E and at one univalent of the 49-chromosome-containing plants containing the haploid Ae. markgrafii genome added to wheat. The absence of both centromeric histone variant CENH3 and attachment of spindle fibers, proven by immunostaining with antibodies against CENH3 and tubulin, respectively, revealed that the univalent elongation of chromosome E is not caused by a classical plant neocentromere.

    If fully stretched out, a typical bacterial chromosome would be nearly 1 mm long, approximately 1,000 times the length of a cell. Not only must cells massively compact their genetic material, but they must also organize their DNA in a manner that is compatible with a range of cellular processes, including DNA replication, DNA repair, homologous recombination, and horizontal gene transfer. Recent work, driven in part by technological advances, has begun to reveal the general principles of chromosome organization in bacteria. Here, drawing on studies of many different organisms, we review the emerging picture of how bacterial chromosomes are structured at multiple length scales, highlighting the functions of various DNA-binding proteins and the impact of physical forces. Additionally, we discuss the spatial dynamics of chromosomes, particularly during their segregation to daughter cells. Although there has been tremendous progress, we also highlight gaps that remain in understanding chromosome organization and segregation. PMID:26566111

  11. X-Chromosome dosage compensation.

    Science.gov (United States)

    Meyer, Barbara J

    2005-01-01

    In mammals, flies, and worms, sex is determined by distinctive regulatory mechanisms that cause males (XO or XY) and females (XX) to differ in their dose of X chromosomes. In each species, an essential X chromosome-wide process called dosage compensation ensures that somatic cells of either sex express equal levels of X-linked gene products. The strategies used to achieve dosage compensation are diverse, but in all cases, specialized complexes are targeted specifically to the X chromosome(s) of only one sex to regulate transcript levels. In C. elegans, this sex-specific targeting of the dosage compensation complex (DCC) is controlled by the same developmental signal that establishes sex, the ratio of X chromosomes to sets of autosomes (X:A signal). Molecular components of this chromosome counting process have been defined. Following a common step of regulation, sex determination and dosage compensation are controlled by distinct genetic pathways. C. elegans dosage compensation is implemented by a protein complex that binds both X chromosomes of hermaphrodites to reduce transcript levels by one-half. The dosage compensation complex resembles the conserved 13S condensin complex required for both mitotic and meiotic chromosome resolution and condensation, implying the recruitment of ancient proteins to the new task of regulating gene expression. Within each C. elegans somatic cell, one of the DCC components also participates in the separate mitotic/meiotic condensin complex. Other DCC components play pivotal roles in regulating the number and distribution of crossovers during meiosis. The strategy by which C. elegans X chromosomes attract the condensin-like DCC is known. Small, well-dispersed X-recognition elements act as entry sites to recruit the dosage compensation complex and to nucleate spreading of the complex to X regions that lack recruitment sites. In this manner, a repressed chromatin state is spread in cis over short or long distances, thus establishing the

    Full Text Available Orientation: Organisational change outcomes in private intensive care units are linked to higher patient satisfaction, improved quality of patient care, family support, cost-effective care practices and an increased level of excellence. Transformational leadership and fostering a positive organisational culture can contribute to these change outcomes.Research purpose: The study determined whether transformational leadership and a supportive organisational culture were evident in six private intensive care units in the Eastern Cape, South Africa. A conceptual framework to investigate the relationship between transformational leadership, organisational culture, and organisational change outcomes, was proposed and tested.Motivation for the study: The prevalence of transformational leadership, a positive organisational culture and their effect on organisational change outcomes in private healthcare industries require further research in order to generate appropriate recommendations.Research design, approach and method: A positivistic, quantitative design was used. A survey was conducted using a questionnaire which, in previous studies, produced scores with Cronbach’s alpha coefficients greater than 0.80, to collect data from a sample of 130 professional nurses in private intensive care units.Main findings: Transformational leadership and a positive organisational culture were evident in the private intensive care units sampled. A strong, positive correlation exists between transformational leadership, organisational culture, and organisational change outcomes. This correlation provides sufficient evidence to accept the postulated research hypotheses. Innovation and intellectual stimulation were identified as the factors in need of improvement.Practical or managerial implications: The findings of the study may be used by managers in intensive care units to promote organisational change outcomes, linked to transformational leadership and a positive

  13. Organisational reviews - requirements, methods and experience. Progress report 2006

    International Nuclear Information System (INIS)

    Organisational reviews are important instruments in the continuous quest for improved performance. In the nuclear field there has been an increasing regulatory interest in organisational performance, because incidents and accidents often point to organisational deficiencies as one of the major precursors. Many methods for organisational reviews have been proposed, but they are mostly based on ad hoc approaches to specific problems. The absence of well-established techniques for organisational reviews has already shown to cause discussions and controversies on different levels. The aim of the OrRe project is to collect the experiences from organisational reviews carried out so far and to reflect them in a theoretical model of organisational performance. Furthermore, the project aims to reflect on the criteria for the definition of the scope and content of organisational reviews. Finally, recommendations will be made for guidance for people participating in organisational reviews. This progress report describes regulatory practices in Finland and Sweden together with some case examples of organizational reviews and assessment in both countries. Some issues of concern are raised and an outline for the next year's work is proposed. Issues of concern include the sufficient depth of the assessment, the required competence in assessments, data and criteria problems, definition of the boundaries of the system to be assessed, and the necessary internal support and organisational maturity required for successful assessments. Finally, plans for next year's work are outlined. (au)

  15. Barriers of inter-organisational integration in vocational rehabilitation

    Directory of Open Access Journals (Sweden)

    Ulla Wihlman

    2008-06-01

    Full Text Available Introduction: A project of vocational rehabilitation was studied in Sweden between 1999 and 2002. The project included four public organisations: the social insurance office, the local health services, the municipal social service and the office of the state employment service. The aim of this paper was to analyse perceived barriers in the development of inter-organisational integration. Theory: Theories of inter-professional and inter-organisational integration, and theories on organisational change. Methods: In total, 51 semi-structured interviews and 14 focus group discussions were performed with actors within the project between 1999 and 2002. A thematic approach was used for the analysis of the data. Results: Three different main themes of barriers emerged from the data: A Uncertainty, B Prioritising own organisation and C Lack of communication. The themes are interconnected in an intricate web and hence not mutually exclusive. Conclusions and discussion: The barriers found are all related partly to organisational change in general and partly to the specific development of organisational integration. Prioritising of own organisation led to flaws in communication, which in turn led to a high degree of uncertainty within the project. This can be seen as a circular relationship, since uncertainty might increase focus on own organisation and lack of communication. A way to overcome these barriers would be to take the needs of the clients as a point of departure in the development of joint services and to also involve them in the development of inter-organisational integration.

    Full Text Available Orientation: The role of leadership and human resources (HRM at the managerial level in the economic zones to implement organisational change have been well described in developing countries although they are often not well documented.Research purpose: The purpose of this article is to investigate the relationship between leadership, organisational behaviour and HRM in Dhaka export processing zone (DEPZ enterprises.Motivation for the study: This study has given a direction for implementing organisational change in DEPZ organisations, where leadership, organisational behaviour and HRM have significant effects on organisational change.Research design, approach and method: The author completed a survey using a structured questionnaire on 53 enterprises in the DEPZ. The sample size was 216. The author tested the research hypotheses by using statistical tools like step-wise multiple regression analysis. The author also used Pearson correlations, a t-test, an ANOVA and a radar diagram in this study.Main findings: The results provide evidence that leadership behaviour, organisational behaviour factors and HRM practices have direct relationships with organisational change. In short, it requires high level of leadership ability, employee motivation and commitment, recruitment, performance appraisal and reward to bring about effective organisational change.Practical/managerial implications: The results show that organisational learning, transformational and transactional leadership, compensation and unionisation practices reinforce organisational change at DEPZ enterprises.Contribution/value-add: The results of this study show that organisational change requires integration with leadership ability, organisational behaviour and HRM practices, which are useful for developing companies, industries and the national economy.

  19. Molecular mechanisms in the induction of chromosome aberrations

    International Nuclear Information System (INIS)

    In more recent years there have been attempts to understand the mechanisms giving rise to aberrations on a more molecular basis. This was initially stimulated by the demonstrations of enzyme repair systems in bacteria which repair mutagen-damaged DNA and the obvious suggestion that similar kinds of repair processes in eukaryotes could be responsible for spontaneous and mutagen-induced exchanges in somatic cells, and for recombinational exchanges in meiotic cells. This impetus has been maintained largely by discovery and the acquisition of information on five fronts: (i) increasing knowledge of the and organisation of the eukaryotic chromosome; (ii) a better understanding of the types of lesions induced in DNA by a wide variety of mutagens; (iii) the demonstrations of a variety of repair systems that restore damaged DNA in eukaryotes including man; (iv) the identification and characterisation of mutants defective in DNA repair and which give unusual reponses to aberration induction by specific mutagens; (v) the development of new techniques to visulise sister chromatid exchange and other facets of chromosome substructure. In this presentation some developments are considered and a picture is sketched of our current notions on how recent chromosomal aberrations are formed, by posing a number of questions and attempting to answer them.

    Work from several laboratories over the past 10-15 years has revealed that, within the interphase nucleus, chromosomes are organized into spatially distinct territories [T. Cremer, C. Cremer, Chromosome territories, nuclear architecture and gene regulation in mammalian cells, Nat. Rev. Genet. 2 (2001) 292-301 and T. Cremer, M. Cremer, S. Dietzel, S. Muller, I. Solovei, S. Fakan, Chromosome territories-a functional nuclear landscape, Curr. Opin. Cell Biol. 18 (2006) 307-316]. The overall compaction level and intranuclear location varies as a function of gene density for both entire chromosomes [J.A. Croft, J.M. Bridger, S. Boyle, P. Perry, P. Teague,W.A. Bickmore, Differences in the localization and morphology of chromosomes in the human nucleus, J. Cell Biol. 145 (1999) 1119-1131] and specific chromosomal regions [N.L. Mahy, P.E. Perry, S. Gilchrist, R.A. Baldock, W.A. Bickmore, Spatial organization of active and inactive genes and noncoding DNA within chromosome territories, J. Cell Biol. 157 (2002) 579-589] (Fig. 1A, A'). In prophase, when cyclin B activity reaches a high threshold, chromosome condensation occurs followed by Nuclear Envelope Breakdown (NEB) [1]. At this point vertebrate chromosomes appear as compact structures harboring an attachment point for the spindle microtubules physically recognizable as a primary constriction where the two sister chromatids are held together. The transition from an unshaped interphase chromosome to the highly structured mitotic chromosome (compare Figs. 1A and B) has fascinated researchers for several decades now; however a definite picture of how this process is achieved and regulated is not yet in our hands and it will require more investigation to comprehend the complete process.

  2. Shape Transitions and Chiral Symmetry Breaking in the Energy Landscape of the Mitotic Chromosome

    2016-06-01

    We derive an unbiased information theoretic energy landscape for chromosomes at metaphase using a maximum entropy approach that accurately reproduces the details of the experimentally measured pairwise contact probabilities between genomic loci. Dynamical simulations using this landscape lead to cylindrical, helically twisted structures reflecting liquid crystalline order. These structures are similar to those arising from a generic ideal homogenized chromosome energy landscape. The helical twist can be either right or left handed so chiral symmetry is broken spontaneously. The ideal chromosome landscape when augmented by interactions like those leading to topologically associating domain formation in the interphase chromosome reproduces these behaviors. The phase diagram of this landscape shows that the helical fiber order and the cylindrical shape persist at temperatures above the onset of chiral symmetry breaking, which is limited by the topologically associating domain interaction strength.

    The gametocidal (Gc) chromosome from Aegilops spp induces chromosome mutation, which is introduced into common wheat as a tool of chromosome manipulation for genetic improvement. The Gc chromosome functions similar to a restriction-modification system in bacteria, in which DNA methylation is an important regulator. We treated root tips of wheat carrying Gc chromosomes with the hypomethylation agent 5-azacytidine; chromosome breakage and micronuclei were observed in these root tips. The frequency of aberrations differed in wheat containing different Gc chromosomes, suggesting different functions inducing chromosome breakage. Gc chromosome 3C caused the greatest degree of chromosome aberration, while Gc chromosome 3C(SAT) and 2C caused only slight chromosome aberration. Gc chromosome 3C induced different degrees of chromosome aberration in wheat varieties Triticum aestivum var. Chinese Spring and Norin 26, demonstrating an inhibition function in common wheat.

    Full Text Available Abstract Background Many hospitals have taken actions to make care delivery for specific patient groups more process-oriented, but struggle with the question how to deal with process orientation at hospital level. The aim of this study is to report and discuss the experiences of hospitals with implementing process-oriented organisation designs in order to derive lessons for future transitions and research. Methods A literature review of English language articles on organisation-wide process-oriented redesigns, published between January 1998 and May 2009, was performed. Results Of 329 abstracts identified, 10 articles were included in the study. These articles described process-oriented redesigns of five hospitals. Four hospitals tried to become process-oriented by the implementation of coordination measures, and one by organisational restructuring. The adoption of the coordination mechanism approach was particularly constrained by the functional structure of hospitals. Other factors that hampered the redesigns in general were the limited applicability of and unfamiliarity with process improvement techniques. Conclusions Due to the limitations of the evidence, it is not known which approach, implementation of coordination measures or organisational restructuring (with additional coordination measures, produces the best results in which situation. Therefore, more research is needed. For this research, the use of qualitative methods in addition to quantitative measures is recommended to contribute to a better understanding of preconditions and contingencies for an effective application of approaches to become process-oriented. Hospitals are advised to take the factors for failure described into account and to take suitable actions to counteract these obstacles on their way to become process-oriented organisations.

    Species of the legume genera Lathyrus and Pisum possess chromosomes that exhibit a unique structure of their centromeric regions, which is clearly apparent during metaphase by the formation of extended primary constrictions which span up to a third of the length of the chromosome. In addition, these species express two different variants of the CenH3 protein which are co-localized in multiple domains along the poleward surface of the primary constrictions. Here, we show that the constrictions...

  10. Organising Ethics: The Case of the Norwegian Army

    Directory of Open Access Journals (Sweden)

    Ellen-Marie Forsberg

    2012-05-01

    Full Text Available This article shows how institutionalism, a theory in organisational social science, provides a model for diagnosing organisational challenges that influence the ethical practices and integration in the Norwegian Army. Institutionalism provides tools for analysing the differences between expressed values and actual practices and for understanding the organisational dynamics that unfold at the crossroads of the organisation's formal structure, informal culture and stakeholder relations. In this article we present and discuss such differences and dynamics in the Norwegian Army based on findings from a survey and a number of workshops. We also provide some suggestions for effective implementation of strategies for strengthening ethics in such an organisation. We argue that the perspective taken in this project is also relevant for other highly professionalised complex organisations and that such interdisciplinary research will strengthen practical ethics' potential for real impact.http://dx.doi.org/10.5324/eip.v6i1.1779

  11. Digital Ecosystems: Self-Organisation of Evolving Agent Populations

    CERN Document Server

    Briscoe, Gerard

    2008-01-01

    A primary motivation for research in digital ecosystems is the desire to exploit the self-organising properties of natural ecosystems, because they are thought to be robust, scalable architectures that can automatically solve complex, dynamic problems. Self-organisation is perhaps one of the most desirable features in the systems that we design, and it is important for us to be able to measure such self-organising behaviour. We investigate the self-organising aspects of Digital Ecosystems, created by the application of evolutionary computing to Multi-Agent Systems aiming to determine a macroscopic variable to characterise the self-organisation of the evolving agent populations within our Digital Ecosystem. We study a measure for self-organisation called Physical Complexity, which is based on statistical physics, automata theory, and information theory. It provides a measure of the quantity of information in an organism's genome, relative to the environment in which it evolves, by calculating the entropy in th...

  14. Numerous transitions of sex chromosomes in Diptera.

    Directory of Open Access Journals (Sweden)

    Beatriz Vicoso

    2015-04-01

    Full Text Available Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six chromosomal arms (five large rods and a small dot, but superficially similar karyotypes may conceal the true extent of sex chromosome variation. Here, we use whole-genome analysis in 37 fly species belonging to 22 different families of Diptera and uncover tremendous hidden diversity in sex chromosome karyotypes among flies. We identify over a dozen different sex chromosome configurations, and the small dot chromosome is repeatedly used as the sex chromosome, which presumably reflects the ancestral karyotype of higher Diptera. However, we identify species with undifferentiated sex chromosomes, others in which a different chromosome replaced the dot as a sex chromosome or in which up to three chromosomal elements became incorporated into the sex chromosomes, and others yet with female heterogamety (ZW sex chromosomes. Transcriptome analysis shows that dosage compensation has evolved multiple times in flies, consistently through up-regulation of the single X in males. However, X chromosomes generally show a deficiency of genes with male-biased expression, possibly reflecting sex-specific selective pressures. These species thus provide a rich resource to study sex chromosome biology in a comparative manner and show that similar selective forces have shaped the unique evolution of sex chromosomes in diverse fly taxa.

    Chromosome analysis of a newborn boy with Down syndrome resulted in the identification of a family with an unusual derivative chromosome 22. The child has 46 chromosomes, including two chromosomes 21, one normal chromosome 22, and a derivative chromosome 22. Giemsa banding and fluorescent in situ hybridization (FISH) studies show that the derivative chromosome is chromosome 22 with evidence of both paracentric and pericentric inversions, joined to the long arm of chromosome 21 from 21q21.2 to qter. The rearrangement results in partial trisomy 21 extending from 21q21.2 to 21q terminus in the patient. The child's mother, brother, maternal aunt, and maternal grandmother are all carriers of the derivative chromosome. All have 45 chromosomes, with one normal chromosome 21, one normal chromosome 22, and the derivative chromosome 22. The rearrangement results in the absence of the short arm, the centromere, and the proximal long arm of chromosome 21 (del 21pter-21q21.2) in carriers. Carriers of the derivative chromosome in this family have normal physical appearance, mild learning disabilities and poor social adjustment. PMID:9182781

    The traditional approach to information systems development has proved to be too monolithic for dealing with highly complex, multidimensional, organisational change issues. In the traditional paradigm, little attempt is made in understanding how the proposed system relates to other organisational components or the effect that the system will have on the enterprise itself. This lack of knowledge ramifies throughout the system development process, making it difficult to identify organisational ...

  13. Meiosis and chromosome painting of sex chromosome systems in Ceboidea.

    Science.gov (United States)

    Mudry, M D; Rahn, I M; Solari, A J

    2001-06-01

    The identity of the chromosomes involved in the multiple sex system of Alouatta caraya (Aca) and the possible distribution of this system among other Ceboidea were investigated by chromosome painting of mitotic cells from five species and by analysis of meiosis at pachytene in two species. The identity of the autosome #7 (X2) involved in the multiple system of Aca and its breakage points were demonstrated by both meiosis and chromosome painting. These features are identical to those described by Consigliere et al. [1996] in Alouatta seniculus sara (Assa) and Alouatta seniculus arctoidea (Asar). This multiple system was absent in the other four Ceboidea species studied here. However, data from the literature strongly suggest the presence of this multiple in other members of this genus. The presence of this multiple system among several species and subspecies that show high levels of chromosome rearrangements may suggest a special selective value of this multiple. The meiotic features of the sex systems of Aca and Cebus apella paraguayanus (Cap) are strikingly different at pachytene, as the latter system is similar to the sex pair of man and other primates. The relatively large genetic distances between species presently showing this multiple system suggest that its origin is not recent. Other members of the same genus should be investigated at meiosis and by chromosome painting in order to know the extent and distribution of this complex sex-chromosome system. PMID:11376445

  18. Organisational Culture in Construction: An Employee Perspective

    Directory of Open Access Journals (Sweden)

    Raufdeen Rameezdeen

    2012-11-01

    Full Text Available A large number of stakeholders in construction projects makes the construction industry prone to disputes. The historical separation between design and construction add to this phenomenon by having a consultant for design and a contractor for construction. Communication breakdown, frequently, is the first sign of problems, notably in the relationship between the Contractor and the Consultant. Therefore, it appears that the split between design and construction has given rise to two separate cultures in the construction industry. This paper attempts to identify whether there is a difference in organisational culture between Consultants and Contractors taken as two groups and determine whether a specific attribute was related to the cultural differences between the two entities. Based on case studies it was found that consultants are biased towards Clan culture while contractors are biased towards Market culture. However, both groups show similar affinity to Adhocracy and Hierarchy cultures.

    We list the chromosome numbers for 65 species of Neotropical Hesperiidae and 104 species or subspecies of Pieridae. In Hesperiidae the tribe Pyrrhopygini have a modal n = 28, Eudaminae and Pyrgini a modal n = 31, while Hesperiinae have n = around 29. Among Pieridae, Coliadinae have a strong modal n = 31 and among Pierinae Anthocharidini are almost fixed for n = 15 while Pierini vary with n = 26 as the most common chromosome number. Dismorphiinae show wide variation. We discuss these results in the context of chromosome numbers of over 1400 Neotropical butterfly species and subspecies derived from about 3000 populations published here and in earlier papers of a series. The overall results show that many Neotropical groups are characterized by karyotype instability with several derived modal numbers or none at all, while almost all taxa of Lepidoptera studied from the other parts of the world have one of n = 29-31 as modal numbers. Possibly chromosome number changes become fixed in the course of speciation driven by biotic interactions. Population subdivision and structuring facilitate karyotype change. Factors that stabilize chromosome numbers include hybridization among species sharing the same number, migration, sexual selection and possibly the distribution of chromosomes within the nucleus.

    2010-03-01

    Full Text Available Orientation: As background to the study it can be stated that the ethical conduct of employees in an organisation is of paramount importance to the successful operations of an organisation, both real and perceived. In recent times the ethical conduct of employees has received extensive publicity and, as such, has emphasised the impact of organisational ethics on the global competitiveness of organisations.Research purpose: The main aim of the paper is to analyse the impact of business ethics in the Eastern Cape Motor Industry Cluster (ECMIC and the different perceptions regarding such ethics. This is based on the main research question, namely, whether a business ethics model should be developed to assist in creating an ethical organisation.Motivation of the study: The motivation for this study is based on the question of whether there is a dedicated drive within the motor industry to establish an ethical organisation and, if such is the case, what benefits would accrue to the organisations in ECMIC.Research design, approach and method: An empirical study was conducted within ECMIC to test the proposed ethics intervention model. A questionnaire, as the main measuring instrument, was developed and 150 questionnaires were distributed. Statistical hypothesis testing was used, with a significance level set at 5%. The aim of the hypothesis testing was to test whether the percentage responses in certain categories were significantly higher than a pre-determined test-value.Main findings: The research results substantiate the fact that the majority of the surveyed organisations do not implement specific ethics interventions. Nevertheless, the majority of respondents acknowledge the importance of ethical behaviour in the organisation, especially with regard to their financial positions.Practical/managerial implications: From this study it became clear that the implementation of a code of ethics would create a platform for ethical behaviour in

    Strategic planning designs the general setting and the strategic principles of a healthcare system, as well as the general guidelines that govern the development of a health system. Strategic service-organisation plans deal with translating healthcare policies into service policies and respond, principally, to the need for services; these give rise to problems that require a solution. They are developed in line with advances in scientific knowledge, the implementation and current characteristics of the healthcare services and the evolution in the competences of professional teams. There are five stages for their development: identification of health/service requirements; prioritisation of needs in health/services; definition of and agreement on service organisation models (care model and service portfolio); the preparation of and agreement on territorial action plans; introduction and evaluation. A conceptual framework is presented along with practical applications carried out in Catalonia. PMID:19195478

    The three-dimensional organization of a genome plays a critical role in regulating gene expression, yet little is known about the machinery and mechanisms that determine higher-order chromosome structure. Here we perform genome-wide chromosome conformation capture analysis, fluorescent in situ hybridization (FISH), and RNA-seq to obtain comprehensive three-dimensional (3D) maps of the Caenorhabditis elegans genome and to dissect X chromosome dosage compensation, which balances gene expression between XX hermaphrodites and XO males. The dosage compensation complex (DCC), a condensin complex, binds to both hermaphrodite X chromosomes via sequence-specific recruitment elements on X (rex sites) to reduce chromosome-wide gene expression by half. Most DCC condensin subunits also act in other condensin complexes to control the compaction and resolution of all mitotic and meiotic chromosomes. By comparing chromosome structure in wild-type and DCC-defective embryos, we show that the DCC remodels hermaphrodite X chromosomes into a sex-specific spatial conformation distinct from autosomes. Dosage-compensated X chromosomes consist of self-interacting domains (~1 Mb) resembling mammalian topologically associating domains (TADs). TADs on X chromosomes have stronger boundaries and more regular spacing than on autosomes. Many TAD boundaries on X chromosomes coincide with the highest-affinity rex sites and become diminished or lost in DCC-defective mutants, thereby converting the topology of X to a conformation resembling autosomes. rex sites engage in DCC-dependent long-range interactions, with the most frequent interactions occurring between rex sites at DCC-dependent TAD boundaries. These results imply that the DCC reshapes the topology of X chromosomes by forming new TAD boundaries and reinforcing weak boundaries through interactions between its highest-affinity binding sites. As this model predicts, deletion of an endogenous rex site at a DCC-dependent TAD boundary using

    2016-02-01

    Full Text Available Orientation: Crises that threaten an organisation’s continued existence cannot be seen in isolation when considering the perception of threats to individual job security. These threats often go hand in hand with employee panic.Research purpose: The aim of this study was to establish a model to assist organisations in managing employee emotionality and panic during times of crisis.Motivation for the study: Environmental crises threaten organisations’ existence, threatening employees’ livelihood and resulting in employee panic. Panic reduces employees’ contributions. Organisations that are successful harness employee contributions at all times.Research design, approach, and method: A modernist qualitative research methodology was adopted, which included a case study as research strategy, purposive sampling to select 12 research participants, semi-structured interviews for data gathering, focus groups for data verification, and the use of grounded theory for data analysis.Main findings: An organisation’s ability to manage employee panic depends on the relationship between the foundational elements of authentic leadership, crisis readiness, resilience practices, versatile and committed talent, strategic management, quality management, and coherence actions taken during the crisis, which include crisis leadership, ongoing visible communication, mindfulness, work flexibility, and decisions based on the greatest financial need and social support.Practical/managerial implications: The study provides a best-practice option for managing emotionality during crises for the case organisation and other organisations within the vehicle components and other manufacturing industries.Contribution/value-add: The Coherence Hexagons Model is presented as a tool to manage employee panic during crisis.Keywords: crisis management; employee emotionality; employee panic; authentic leadership; talent management
