Breastfeeding Systematic Review of Psychometric Properties of A SF )-( BSES Short Form-Efficacy Scale-Self

Background: The breastfeeding self-efficacy is one of the psychological factors affecting the duration of breastfeeding; the Breastfeeding self-efficacy measured by the breastfeeding self-efficacy scaleshort form (BSES-SF). It was validated and reliable in several studies. The current systematic review aimed to comprehensively review the validity and reliability of the BSES-SF in various versions to give comprehensive information for authorities in this field. Materials and Methods: We searched English databases, including Medline (via PubMed), Scopus, Cochran library and Web of Science since inception to May 2018 to find all previously published reports the psychometric dimensions of the Breastfeeding Self-Efficacy. Two reviewers read independently extracted data assessed. The quality of the studies was carried out by the Consensusbased standards for the selection of health status Measurement instruments (COSMIN) checklist. Results: In this systematic review, reliability was measured using Cronbach’s alpha; inter coefficient of correlation (ICC) as well as an analysis of the item-total correlation. Cronbach’s alpha of breastfeeding self-efficacy for whole scale ranged from 0.76 to 0.95 considered moderate to excellent. Only two studies assessed test-retest reliability. One study reported correlation between two time intervals that was high (r=0.94) and another study measured test-retest reliability using ICC. It was ranged from 0.69 to 0.78 that consider suitable. Item-total correlation ranged from 0.23 to 0.85. Construct validity was tested using factor analysis. Original onefactor structure was confirmed in Spanish, Chinese, American, Canadian, Brazilian and Creation version. Some studies reported four and six –factor structure. Confirmatory factor analysis (CFA) confirmed one-factor structure. Conclusion: Original onefactor structure was confirmed in Spanish, Chinese, American, Canadian, Swedish, and Japanese, creation, Turkish, Portuguese, Brazilian and Creation; version six and fourfactor need to further test in future studies. This study provides evidence also that the modified BSESSF may be a valid and reliable measure of breastfeeding self-efficacy.
GRAVITATIONAL EFFECTS ON GLUCOSE DIFFUSION INTO ARTICULAR CARTILAGE TISSUE

Cartilage has the ability to bear mechanical stress without distortion. It is avascular, so nutrients and oxygen must diffuse through the extracellular matrix to reach the cells. Changes in nutrient availability could alter cell metabolism and ultimately cartilage structure and function. The objective of this project was to determine if glucose diffusion into cartilage was altered in a microgravity (MG) or hypergravity (HG) environment compared to controls at standard 1x gravity (1xG). The experiments were conducted in parabolic flight aboard the NASA C-9 aircraft. A flight-certified apparatus consisting of three interconnected syringes contained each experiment on the aircraft. Bovine articular cartilage was exposed to a fluorescent labeled glucose solution for 20 seconds during the MG, HG or 1xG episodes during flight. The amount of glucose that diffused into the tissue was quantitated. There was no significant difference in the wet or dry weights of the samples. The total amount of glucose that diffused into cartilage during MG and HG was significantly less than at 1xG by 23% and 27%, respectively. The amount of glucose per tissue wet weight was reduced in the samples exposed to MG and HG compared to 1xG controls, but they were not significant. However, the amount of glucose per tissue dry weight was significantly less in the MG (26%) and HG (41%) samples than at 1xG. Tissue fluid volume may not be as important for diffusion in MG and HG as the structural components of the matrix. Since diffusion is reduced in both MG and HG, two different mechanisms, such as matrix conformation and tissue fluid flow, may be responsible. This suggests that cartilage nutrition may be impaired in different gravitational environments.

The Study of Relationship between Leadership Styles (Transformational/ Transactional) and Knowledge Conversion Processes among Faculty Members in University

Nowadays, leaders face the challenge of being effective in a global knowledge environment. Now, more than ever, leaders must play the key role in helping organizations cope with the challenges they face from knowledge systems. The purpose of this research was to investigate the relationship between leadership style (transformational/transactional) and Knowledge conversion processes among employees of University. This study was conducted using the correlation method. 90 faculty members of University of Isfahan were chosen by using stratified randomized sampling as a sample case. The results have indicated that there is a positive and significant relationship between transformational leadership style and Knowledge conversion processes dimensions. In addition, there is no significant difference between faculty members' knowledge conversion process & leadership style considering the variables of age, gender, and field of study and employment status.
Gender equity in education: An analysis of perceptions of Masvingo urban female students, parents and teachers towards the maternity leave policy for high school girls in Zimbabwe

The study examined the perceptions of Masvingo urban female students, parents and teachers towards the maternity leave policy for high school girls in Zimbabwe. A qualitative paradigm and the descriptive survey method were adopted. The qualitative paradigm was selected because the issue under study yields soft data. A descriptive survey was suitable for a relatively large sample. The paradigm lends itself to the use of in-depth interviews and open-ended questionnaires which were the two instruments used to collect data from sixty-eight purposively sampled respondents from a population of forty-eight teachers and two hundred and twenty students from thirteen high schools. Collected data were presented in narrative form and qualitatively analysed. The main findings revealed that most parents, students and teachers were against the policy whilst a few were in favour although parents and teachers wanted it to be amended and reduced to a mere disciplinary document which is known to administrators only. It is recommended that Ministry authorities should consult stakeholders before introducing policies which are sensitive in nature. Key words: Gender equity, teenage, teenage pregnancy, maternity leave, female.

Homologous recombination: a Swiss Army knife for protecting genome integrity

The genetic information required for life is stored in our DNA. However, every day our cells are exposed to variety of DNA damaging agents. Additionally, endogenous metabolic processes can also be a source of DNA damage. An inability to properly repair DNA leads to genome instability, which is a hallmark of both ageing and cancer. To protect genome integrity, cells have developed pathways to repair DNA damage. Homologous recombination (HR), a major DNA repair pathway, is often associated with the repair of DNA double-strand breaks (DSBs). A DSB is the most lethal type of DNA damage; one single unrepaired DSB is enough to kill a cell. During my PhD, I have been particularly interested in understanding how HR is used to maintain genome integrity, both generally throughout the entire genome and specifically at telomeres. Telomeres are nucleoprotein structures located at the ends of linear chromosomes that help cells distinguish chromosome ends from DSBs. Telomeres shorten due to incomplete DNA replication and nucleolytic degradation. Telomere shortening is also associated with ageing. I have shown that HR proteins are important to repair damage at telomeres, thereby preventing accelerated cellular ageing. I have also quantified HR activity genome-wide by measuring and mapping HR events known as sister chromatid exchanges (SCEs). SCEs are commonly thought to occur as a result of DSB repair, but I have determined that this is not the case for the majority of spontaneous SCE events that occur in wild-type cells.
Structure from motion (SFM) photogrammetry

Topographic data measurement is a fundamental aspect of many geomorphic research applications, particularly those including landform monitoring and investigation of changes in topography. However, most surveying techniques require relatively expensive technologies or specialized user supervision. Structure from Motion (SfM) photogrammetric technology reduces both these constraints by allowing the use of consumer grade digital cameras and highly automated data processing, which can be free to use. SfM photogrammetry therefore offers the possibility of fast, automated and low-cost acquisition of 3-D data, which has inevitably created great interest amongst the geomorphological community. In this contribution, the basic concepts of SfM photogrammetry are presented, whilst recognising its heritage. A few examples are employed to illustrate the potential of SfM applications for geomorphological research. In particular, SfM photogrammetry offers to geomorphologists a tool for high-resolution characterisation of 3-D forms at a range of scales and for change detection purposes. The high level of automation of SfM data processing creates both opportunities and threats, particularly because user control tends to focus upon visualisation of the final product rather than upon inherent data quality. Accordingly, this contribution seeks to guide potential new users in successfully applying SfM for a range of geomorphic studies.
Non-spherical bubble dynamics in a compressible liquid. Part 2. Acoustic standing wave

This paper investigates the behaviour of a non-spherical cavitation bubble in an acoustic standing wave. The study has important applications to sonochemistry and in understanding features of therapeutic ultrasound in the megahertz range, extending our understanding of bubble behaviour in the highly nonlinear regime where jet and toroidal bubble formation may be important. The theory developed herein represents a further development of the material presented in Part 1 of this paper (Wang & Blake, J. Fluid Mech. vol. 659, 2010, pp. 191–224) to a standing wave, including repeated topological changes from a singly to a multiply connected bubble. The fluid mechanics is assumed to be compressible potential flow. Matched asymptotic expansions for an inner and outer flow are performed to second order in terms of a small parameter, the bubble-wall Mach number, leading to weakly compressible flow formulation of the problem. The method allows the development of a computational model for non-spherical bubbles by using a modified boundary-integral method. The computations show that the bubble remains approximately of a spherical shape when the acoustic pressure is small or is initiated at the node or antinode of the acoustic pressure field. When initiated between the node and antinode at higher acoustic pressures, the bubble loses its spherical shape at the end of the collapse phase after only a few oscillations. A high-speed liquid bubble jet forms and is directed towards the node, impacting the opposite bubble surface and penetrating through the bubble to form a toroidal bubble. The bubble first rebounds in a toroidal form but re-combines to a singly connected bubble, expanding continuously and gradually returning to a near spherical shape. These processes are repeated in the next oscillation.
The Effect of PICTK and TPACK Knowledge on ICT Instructors' Sense ofEmpowerment

The implementation of technology in the national Information and Communication Technology (ICT) program is supported by instructors who act according to the program's outputs. The current research has two goals: to examine the predictive variables of ICT instructors who instruct at the district level (henceforth: ―district ICT instructors‖) compared to ICT instructors who instruct at both the district andthe school levels(henceforth: ―district-school ICT instructors‖) and to examine the effect of Program Information Communication Technology Knowledge (PICTK) and Technology Pedagogy and Content Knowledge (TPACK) on the ICT instructors' sense of empowerment for facilitating the implementation of ICT in schools. One hundred and twenty-one ICT instructors participated in the research: 77 district ICT instructors (64%) and 44 district-school ICT instructors(36%). The research tool consisted of four self-report questionnaires. Path analysis was performed using structural equation analysis. The main results show that PICTK knowledge has a significant positive effect on TPACK knowledge among the district ICT instructors, whereas there was no change among the district-school ICT instructors. The results indicate that PICTK and TPACK knowledge does not necessarily promote the pedagogical-ICT knowledge of the ICT instructor, but is critical for his or her sense of empowerment. It is therefore recommended to continue support for all ICT instructors, and to expand their personal knowledge about the evolving ICT program.
MODIFICATION OF FLOWERING TIME IN OSTEOSPERMUM ECKLONIS L. BY CONSTANS GENE

Altered onset of flowering in crop plants can be achieved by modifying the expression of flowering-time genes. In a few cases, these genes can change the flowering time of species unrelated to the plant from which they were isolated. We pursued this strategy in order to modify the flowering characteristics of the ornamental plant Osteospermum ecklonis. The flowering-time gene CONSTANS (CO) from Arabidopsis thaliana Landsberg erecta was the candidate in our work. This choice was based on literature demonstrating that A. thaliana transgenic plants containing extra copies of the CO gene flower earlier than wild type plants, suggesting that CO expression is sufficient to trigger flowering irrespective of day length. The CO cDNA was cloned in the expression vector pGREEN under the control of the constitutive promoter 35S. Genetic transformation of leaf tissue was performed using Agrobacterium tumefaciens strain AGL1. CO constitutive expression was detected in a checked transgenic clone. The flowering performance of potted transgenic plants was monitored in the greenhouse in comparison to control plants. 35SCO plants produced 30% more flowers than control, retained their ability to flower in June when control plants entered vegetative phase and were still able to produce new flower buds in August.
Proximity and power in collaborative innovation projects

ABSTRACT Proximity and power in collaborative innovation projects. Regional Studies. The proximity literature has so far paid little attention to power relations in collaborative innovation projects. This paper draws on contributions from international business to examine if power constellations between collaborators in innovation projects influence the effects of proximity. An analysis of two cases of collaborations between headquarters and subsidiaries of multinational companies highlights that specific power constellations indeed influence the effects of proximity. While some forms of proximity allow subsidiary-specific capabilities to diffuse throughout the organization and pose a threat to the powerful subsidiary, the weaker subsidiary considers proximity as a possibility to learn from the headquarters.
Wavelet analysis for classification of multi-source PD patterns

Multi-resolution signal decomposition (MSD) technique of wavelet transforms has interesting properties of capturing the embedded horizontal, vertical and diagonal variations within an image in a separable form. This feature was exploited to identify individual partial discharge (PD) sources present in multi-source PD patterns, usually encountered during practical PD measurements. Employing the Daubechies wavelet, features were extracted from the third level decomposed and reconstructed horizontal and vertical component images. These features were found to contain the necessary discriminating information corresponding to the individual PD sources. Suitability of these extracted features for classification was further verified using a radial basis function neural network (NN). Successful recognition was achieved, even when the constituent sources produced partially and fully overlapping patterns, thus demonstrating the applicability of the proposed novel approach for the task of multi-source PD classification.

MODELING GIANT EXTRASOLAR RING SYSTEMS IN ECLIPSE AND THE CASE OF J1407B: SCULPTING BY EXOMOONS?

The light curve of 1SWASP J140747.93-394542.6, a ∼16 Myr old star in the Sco-Cen OB association, underwent a complex series of deep eclipses that lasted 56 days, centered on 2007 April. This light curve is interpreted as the transit of a giant ring system that is filling up a fraction of the Hill sphere of an unseen secondary companion, J1407b. We fit the light curve with a model of an azimuthally symmetric ring system, including spatial scales down to the temporal limit set by the star's diameter and relative velocity. The best ring model has 37 rings and extends out to a radius of 0.6 AU (9 × 107 km), and the rings have an estimated total mass on the order of 100 MMoon. The ring system has one clearly defined gap at 0.4 AU (6.1 × 107 km), which, we hypothesize, is being cleared out by a <0.8 M⊕ exosatellite orbiting around J1407b. This eclipse and model imply that we are seeing a circumplanetary disk undergoing a dynamic transition to an exosatellite-sculpted ring structure, which is one of the first seen outside our solar system.
Demographic Catastrophes Did Not Shape the Growth of Human Population or the Economic Growth

Abstract . Rigorous analysis of demographic catastrophes shows that, individually, they were too weak to shape the growth of human population and of the associated economic growth. On average, only 6.5% of all major demographic catastrophes, associated with the death toll larger than or equal to one million, were potentially strong enough to cause perhaps a minor change in the growth trajectory of the world population, but as shown by the population data, they did not produce any noticeable disturbance. The absence of impacts of demographic catastrophes on the growth of population can be explained not only by their low relative intensity but also by the strong and efficient regenerating process recorded for the first time by Malthus. There was, however, one unusual event manifested in the convergence of five, major demographic catastrophes. They have caused a minor and short-lasting change in the growth trajectory of the world population, which, however, was soon counteracted by the process of regeneration. This analysishows that the dominant force controlling the growth of human population was too strong to be influenced in any substantial way by accidental forces. As explained in an earlier publication, this strong and dominant force driving the growth of population was the force of procreation, which was approximately constant per person, the force expressed as a difference between the ever-present, biologically-controlled,force of sex drive and the ever-present and also biologically-controlled process of aging and dying. Keywords. Demographic catastrophes, Growth of population, Economic growth, Malthusian stagnation, Hyperbolic growth, Mechanism of hyperbolic growth. JEL. A10, A12, A20, B41,C12,Y80.
