This research was conducted to find out how the recruitment process and the factors that influence the Housewife chose to work as a street sweeper in Pekanbaru. Where in this Pekanbaru City street sweeper more women than men. To find out how the recruitment process and factors such mempengaruhui Housewife chose to work as a street sweeper in Pekanbaru, the authors conducted data collection by using the technique of direct interview with the respondents using a list of questions prepared in advance, and also that researchers obsevarsi directly observing the behavior of the respondent. Using purposive sampling technique that researchers have determined the subject of research with the assumption or opinion of himself as a subject research. Results of research conducted that the recruitment process Housewife be a street sweeper in Pekanbaru is relatively easy because the terms are defined not difficult to include are: photocopy KK (family card), a copy of ID card (Identity Card), and a cover letter. Street sweeper is supervised by a foreman at each working area, street sweeper was divided into two, namely: sweeper median (1), sweeper sand (2). The median is the sweeper sweeping trash system with the middle area of the road that separates the space between the right and left of the road, while the sweeper sand or so-called sweeper edge is swept trash system aupun sand with right or left area roads. The husbands income is not sufficient is one of the factors that affect their work as a street sweeper. Allocation of their income to meet their childs school fees in addition to working as a street sweeper they can meet the needs of themselves without having to like buying clothes, veil, powder, and else.Keywords : Motivation , Status and Role , Women and Wor

Pengaruh Career Development Terhadap Succession Dengan Efek Mediasi Organizational Justice Pada PT Sumberdaya Sewatama

This research was conducted in order to determine whether the Organizational Justice has a mediating effect in the influence of Career Development to Succession in a family enterprise in the research, namely PT SumberdayaSewatama. The sampling method used is convenience sampling. This research took a sample of 38 employees at managerial level. Methods of data analysis used in this research is the analysis of the effect of mediation (OJ) and test effect of independent variables (CD) to the dependent variable (S). The results of data processing using SPSS 22 for windows with macros and hayes 2013. The result shows that managerial level employees at PT Sumberdaya Sewatama have career development, organizational justice, and succession were already good, but organizational justice can not mediate the effect of career development to succession

Carabid beetles of tropical dry forests display traits that cope with a harsh environment

The tropical dry forest (TDF) ecosystem is characterised by strong seasonality exasperated periodically by the El Nino/southern oscillation (ENSO). The environment produced by this event could constrain the survival of small organisms, such as insects. Carabid beetles were collected in a TDF in Armero, Colombia, during wet and dry seasons in both El Nino and non-El Nino periods. A series of traits linked to desiccation resistance were measured to characterise their adaptation to the TDF environment and to investigate changes experienced by carabid beetles during both episodes in quantitative (assemblage) and qualitative (traits) parameters. We found no difference in the presence of traits between El Nino and non-El Nino episodes, but carabid assemblages changed significantly in composition and assemblage structure between these episodes. During both periods, small-sized and nocturnal species dominated the assemblages, but in terms of number of individuals, medium and large-sized, and visual hunter species dominated. Calosoma alternans and Megacephala affinis were the most abundant species with high dispersal capacity. Carabid beetles exhibited morphological traits well-adapted to drought experienced in TDF, including when it is exasperated by ENSO. However, long-term studies can help to elucidate the real effects of ENSO and to confirm the adaptation of carabid beetles to cope with this extreme environment.Peer reviewe

Bioengineering of Humanized Bone Marrow Microenvironments in Mouse and Their Visualization by Live Imaging

Human hematopoietic stem cells (HSCs) reside in the bone marrow (BM) niche, an intricate, multifactorial network of components producing cytokines, growth factors, and extracellular matrix. The ability of HSCs to remain quiescent, self-renew or differentiate, and acquire mutations and become malignant depends upon the complex interactions they establish with different stromal components. To observe the crosstalk between human HSCs and the human BM niche in physiological and pathological conditions, we designed a protocol to ectopically model and image a humanized BM niche in immunodeficient mice. We show that the use of different cellular components allows for the formation of humanized structures and the opportunity to sustain long-term human hematopoietic engraftment. Using two-photon microscopy, we can live-image these structures in situ at the single-cell resolution, providing a powerful new tool for the functional characterization of the human BM microenvironment and its role in regulating normal and malignant hematopoiesis

Glyph reader app: multisensory stimulation through ICT to intervene literacy disorders in the classroom

This article shows the experience in the implementation of a tool called Glyph Reader, which is an application that has two interfaces, Web and Mobile and that responds to the need for an educational and interactive resource whose main objective is the Multisensory stimulation for literacy training in a population with cognitive disabilities and/specific learning disorder. The design of the activities that this application has is based on the theoretical model of multisensory stimulation Orton Gillingham, which seeks the development of basic skills for decoding isolated words based on a phonetic - graphic analysis of them. The techniques within this model use the basic concepts of intersensory integration of simultaneous visual-auditory-kinesthetic- tactile differentiation (VAKT), to which the Glyph Reader application takes full advantage, by including graphic phonetic recognition and training activities of syllables/words (exercises with symphons and exercises with combinations of consonants or working syllables), which pass from basic levels to complex levels of decoding, necessary for the development of literacy skills. The study sample for software validation is 250 students from the Eustorgio Salgar educational institution, in the municipality of Puerto Colombia, in the department of Atlántico – Colombi

Effect of the surface model on the theoretical description of the chemisorption of atomic hydrogen on Cu(001)

Adsorption at surfaces can be modelled using a periodic supercell approach or using finite clusters. For many systems and properties these models are complementary and often the most productive way to work is to use a combination of these techniques. If reliable data is to be obtained it is essential that convergence is achieved with respect to the size of supercell and cluster. This work discusses the convergence of chemisorption properties of H on Cu(001) with respect to the cluster size. To this end calculations of the H binding energy and equilibrium distance, are reported for cluster models of increasing size containing up to 77 metal atoms. Likewise, periodic slab model calculations are used to provide the corresponding values towards which the cluster approach should converge. In many previous studies of a wide variety of systems it has been established that computed equilibrium distances converge rapidly with respect to cluster size. Here, a systematic study of the dependence on cluster size shows that, for adsorption in the 4-fold site, convergence is not achieved even for very large clusters. The reason for this poor convergence is seen to be the inability of the cluster model to reproduce accurately the charge density and electrostatic potential of the crystalline surface
