Pengaruh Komitmen Kerja, Stres Kerja Dan Disiplin Kerja Terhadap Kinerja Karyawan Bagian Spinning III PT. Apac Inti Corpora

The need for human resources are not small and labor requirements vary with the complex challenges of the work is a problem for a company. PT. APAC INTI CORPORA engaged in textiles that need to maintain human resources work in order to meet the quantity and quality of the product. However, in 2013 the production and performance of any inconsistency unfavorable assessments on the performance of the employee.The purpose of research to determine the effect of work commitment, job stress, and work discipline on employee performance Spinning Part III PT. APAC INTI CORPORA. This research method is explanatory, data collection through interviews with questionnaires. Proportionate stratified random sampling technique is used with a sample of 87 people. The analysis technique used was qualitative and quantitative. Quantitative analysis using validity, reliability test, correlation coefficient, simple and multiple regression analysis, the coefficient of determination, cross tabulation, and tests of significance.Categorization work commitment is high, but there are some that in the low category. Employee stress is low, but there is still residing in the high category. Discipline employees in good condition, although there is still a lack of good condition. The level of employee performance is good, but there are still employees who have low performance. Results and discussion showed the higher commitment to work, the higher the performance of employees, reduced work stress, the higher the performance of employees, and the better labour discipline, the higher the performance of employees, simultaneously work commitment, work stress, and labour discipline affect employee performance.Companies must increase loyalty to employees, to put forward a conducive atmosphere in work activities, and socializing with good rules, provide counseling regarding the standards and efficiency of work, and the need for further research by the company or outside parties on other variables such motivation, job satisfaction, training work, which can affect employee performance improvement

The bacterial pedome associated with foot pathologies in sheep::a case study

Hoof lameness is considered to be a major health issue in sheep, and can impact on both animal welfare and production of livestock. However the causes, although generally assumed to have a microbiological basis, are poorly understood. The work presented here investigated the pedome (the bacterial community of the foot) of sheep which were seen to have one of the following conditions: foot rot; a toe granuloma; Ovine Interdigital Dermatitis (OID) / scald. These were compared relative to samples collected from the healthy feet of the same animals. Samples were collected from commercial lambs from two flocks of sheep (one Beulahs, one Suffolks) at times of routine husbandry work. All animals in the flocks and those which showed signs of lameness (7 per flock) were used for sample collection. Interdigital scrapes were collected from lame feet, together with controls (i.e. non-lame feet) from the same animals. Of the lame feet, 3 were classified as having foot rot, 10 had OID / scald and 1 had a toe granuloma. DNA was isolated from the interdigital scrapes and analysed by next generation sequencing following amplification of DNA by PCR. All foot rot samples showed unusual microbial communities: one having an elevated abundance of Fusobacterium spp.; another with an elevated level of a Corynebacterium sp.; and the third an increased level of a number of unidentified sequences. One of the OID samples also had a high abundance of Fusobacterium spp., and another had a similar pattern of unknown organisms to that seen in the example of the foot rot case. The toe granuloma case showed an elevated level of a Mycoplasma sp. Therefore the organisms described here are different from those previously identified in a similar investigation into this topic. However the other eight OID samples had patterns similar to those in controls. This suggests microbial communities associated with ovine foot rot are complex, and that there are bacteria associated with the condition which remain unknown

Tree-Based Unrooted Phylogenetic Networks

Phylogenetic networks are a generalization of phylogenetic trees that are used to represent non-tree-like evolutionary histories that arise in organisms such as plants and bacteria, or uncertainty in evolutionary histories. An unrooted phylogenetic network on a non-empty, finite set X of taxa, or network, is a connected, simple graph in which every vertex has degree 1 or 3 and whose leaf set is X. It is called a phylogenetic tree if the underlying graph is a tree. In this paper we consider properties of tree-based networks, that is, networks that can be constructed by adding edges into a phylogenetic tree. We show that although they have some properties in common with their rooted analogues which have recently drawn much attention in the literature, they have some striking differences in terms of both their structural and computational properties. We expect that our results could eventually have applications to, for example, detecting horizontal gene transfer or hybridization which are important factors in the evolution of many organisms.

Functional significance may underlie the taxonomic utility of single amino acid substitutions in conserved proteins

We hypothesized that some amino acid substitutions in conserved proteins that are strongly fixed by critical functional roles would show lineage-specific distributions. As an example of an archetypal conserved eukaryotic protein we considered the active site of ß-tubulin. Our analysis identified one amino acid substitution—ß-tubulin F224—which was highly lineage specific. Investigation of ß-tubulin for other phylogenetically restricted amino acids identified several with apparent specificity for well-defined phylogenetic groups. Intriguingly, none showed specificity for “supergroups” other than the unikonts. To understand why, we analysed the ß-tubulin Neighbor-Net and demonstrated a fundamental division between core ß-tubulins (plant-like) and divergent ß-tubulins (animal and fungal). F224 was almost completely restricted to the core ß-tubulins, while divergent ß-tubulins possessed Y224. Thus, our specific example offers insight into the restrictions associated with the co-evolution of ß-tubulin during the radiation of eukaryotes, underlining a fundamental dichotomy between F-type, core ß-tubulins and Y-type, divergent ß-tubulins. More broadly our study provides proof of principle for the taxonomic utility of critical amino acids in the active sites of conserved proteins

Holistic corpus-based dialectology

This paper is concerned with sketching future directions for corpus-based dialectology. We advocate a holistic approach to the study of geographically conditioned linguistic variability, and we present a suitable methodology, 'corpusbased dialectometry', in exactly this spirit. Specifically, we argue that in order to live up to the potential of the corpus-based method, practitioners need to (i) abandon their exclusive focus on individual linguistic features in favor of the study of feature aggregates, (ii) draw on computationally advanced multivariate analysis techniques (such as multidimensional scaling, cluster analysis, and principal component analysis), and (iii) aid interpretation of empirical results by marshalling state-of-the-art data visualization techniques. To exemplify this line of analysis, we present a case study which explores joint frequency variability of 57 morphosyntax features in 34 dialects all over Great Britain

A Note on Encodings of Phylogenetic Networks of Bounded Level

Driven by the need for better models that allow one to shed light into the question how life's diversity has evolved, phylogenetic networks have now joined phylogenetic trees in the center of phylogenetics research. Like phylogenetic trees, such networks canonically induce collections of phylogenetic trees, clusters, and triplets, respectively. Thus it is not surprising that many network approaches aim to reconstruct a phylogenetic network from such collections. Related to the well-studied perfect phylogeny problem, the following question is of fundamental importance in this context: When does one of the above collections encode (i.e. uniquely describe) the network that induces it? In this note, we present a complete answer to this question for the special case of a level-1 (phylogenetic) network by characterizing those level-1 networks for which an encoding in terms of one (or equivalently all) of the above collections exists. Given that this type of network forms the first layer of the rich hierarchy of level-k networks, k a non-negative integer, it is natural to wonder whether our arguments could be extended to members of that hierarchy for higher values for k. By giving examples, we show that this is not the case
