Midwives’ perspectives of respectful maternity care during childbirth: A qualitative study

The adoption of respectful maternity care during labor and birth is a complex process which needs both scientific and interpersonal skills of providers. In this regard, identifying the potential barriers and applying effective strategies for implementing respectful maternity care are essential. This study aimed to explore the perceptions of Iranian midwives regarding respectful maternity care during labor and childbirth. This was a qualitative study which was conducted from September-December 2018 in two non-teaching public hospitals in Tehran, Iran. Twenty-four semi-structured interviews were conducted with midwives, who had more than one year work experience in labor and childbirth units, through a purposive sampling method. A content analysis approach was used to analyze the data and identify themes. Three themes were extracted including “showing empathy”, “women-centered care” and “protecting rights”. Showing empathy reflects that “establishing a friendly relationship” and “being with women”. Women-centered care encompassed “keeping women safe” and “participating in decision making”. Protecting rights reflected a need for “safeguarding dignity” as well as “giving equal care” and “preparing appropriate environment”. Iranian midwives considered respectful maternity care a broader concept than just preventing mistreatment. Providing supportive care through friendly interaction with women was the first step for providing respectful maternity care. Respectful care is also promoted by providing safe care, implementing evidence-based care and involving women in their care as well as by providing an appropriate environment for women, families and caregivers.
Effects of Titanium Dioxide Nanoparticles on the Hprt Gene Mutations in V79 Hamster Cells

The genotoxicity of anatase/rutile TiO2 nanoparticles (TiO2 NPs, NM105 at 3, 15 and 75 µg/cm2) was assessed with the mammalian in-vitro Hypoxanthine guanine phosphoribosyl transferase (Hprt) gene mutation test in Chinese hamster lung (V79) fibroblasts after 24 h exposure. Two dispersion procedures giving different size distribution and dispersion stability were used to investigate whether the effects of TiO2 NPs depend on the state of agglomeration. TiO2 NPs were fully characterised in the previous European FP7 projects NanoTEST and NanoREG2. Uptake of TiO2 NPs was measured by transmission electron microscopy (TEM). TiO2 NPs were found in cytoplasmic vesicles, as well as close to the nucleus. The internalisation of TiO2 NPs did not depend on the state of agglomeration and dispersion used. The cytotoxicity of TiO2 NPs was measured by determining both the relative growth activity (RGA) and the plating efficiency (PE). There were no substantial effects of exposure time (24, 48 and 72 h), although a tendency to lower RGA at longer exposure was observed. No significant difference in PE values and no increases in the Hprt gene mutant frequency were found in exposed relative to unexposed cultures in spite of evidence of uptake of NPs by cells.
A Cross‐Dimension Annotations Method for 3D Structural Facial Landmark Extraction

Recent methods for 2D facial landmark localization perform well on close‐to‐frontal faces, but 2D landmarks are insufficient to represent 3D structure of a facial shape. For applications that require better accuracy, such as facial motion capture and 3D shape recovery, 3DA‐2D (2D Projections of 3D Facial Annotations) is preferred. Inferring the 3D structure from a single image is an ill‐posed problem whose accuracy and robustness are not always guaranteed. This paper aims to solve accurate 2D facial landmark localization and the transformation between 2D and 3DA‐2D landmarks. One way to increase the accuracy is to input more precisely annotated facial images. The traditional cascaded regressions cannot effectively handle large or noisy training data sets. In this paper, we propose a Mini‐Batch Cascaded Regressions (MBCR) method that can iteratively train a robust model from a large data set. Benefiting from the incremental learning strategy and a small learning rate, MBCR is robust to noise in training data. We also propose a new Cross‐Dimension Annotations Conversion (CDAC) method to map facial landmarks from 2D to 3DA‐2D coordinates and vice versa. The experimental results showed that CDAC combined with MBCR outperforms the‐state‐of‐the‐art methods in 3DA‐2D facial landmark localization. Moreover, CDAC can run efficiently at up to 110 fps on a 3.4 GHz‐CPU workstation. Thus, CDAC provides a solution to transform existing 2D alignment methods into 3DA‐2D ones without slowing down the speed. Training and testing code as well as the data set can be downloaded from https://github.com/SWJTU‐3DVision/CDAC.
Impacts of Operational Failures on Primary Care Physicians’ Work: A Critical Interpretive Synthesis of the Literature

PURPOSE Operational failures are system-level errors in the supply of information, equipment, and materials to health care personnel. We aimed to review and synthesize the research literature to determine how operational failures in primary care affect the work of primary care physicians. METHODS We conducted a critical interpretive synthesis. We searched 7 databases for papers published in English from database inception until October 2017 for primary research of any design that addressed problems interfering with primary care physicians’ work. All potentially eligible titles/abstracts were screened by 1 reviewer; 30% were subject to second screening. We conducted an iterative critique, analysis, and synthesis of included studies. RESULTS Our search retrieved 8,544 unique citations. Though no paper explicitly referred to “operational failures,” we identified 95 papers that conformed to our general definition. The included studies show a gap between what physicians perceived they should be doing and what they were doing, which was strongly linked to operational failures—including those relating to technology, information, and coordination—over which physicians often had limited control. Operational failures actively configured physicians’ work by requiring significant compensatory labor to deliver the goals of care. This labor was typically unaccounted for in scheduling or reward systems and had adverse consequences for physician and patient experience. CONCLUSIONS Primary care physicians’ efforts to compensate for suboptimal work systems are often concealed, risking an incomplete picture of the work they do and problems they routinely face. Future research must identify which operational failures are highest impact and tractable to improvement.
Applying Information Retrieval to the Electronic Health Record for Cohort Discovery and Rare Disease Detection

United States and elsewhere. This has resulted in vast amounts of data that can be re-used for other purposes such as clinical research. However, most of this data is non-standardized and unstructured, making retrieval and other uses challenging. This talk will describe recent research applying and evaluating information retrieval techniques to two use cases: discovering cohorts for clinical research studies and detecting rare diseases.
PERSONALITY PROCESSES AND INDIVIDUAL DIFFERENCES Refining the Theory of Basic Individual Values

We propose a refined theory of basic individual values intended to provide greater heuristic and explanatory power than the original theory of 10 values (Schwartz, 1992). The refined theory more accurately expresses the central assumption of the original theory that research has largely ignored: Values form a circular motivational continuum. The theory defines and orders 19 values on the continuum based on their compatible and conflicting motivations, expression of self-protection versus growth, and personal versus social focus. We assess the theory with a new instrument in 15 samples from 10 countries (N ! 6,059). Confirmatory factor and multidimensional scaling analyses support discrimination of the 19 values, confirming the refined theory. Multidimensional scaling analyses largely support the predicted motivational order of the values. Analyses of predictive validity demonstrate that the refined values theory provides greater and more precise insight into the value underpinnings of beliefs. Each value correlates uniquely with external variables.
One-Factorisations of Complete Graphs Constructed in Desarguesian Planes of Certain Odd Square Orders

A geometric construction of one-factorisations of complete graphs $K_{q(q-1)}$ is provided for the case when either $q=2^d +1$ is a Fermat prime, or $q=9$. This construction uses the affine group $\mathrm{AGL}(1,q)$, points and ovals in the Desarguesian plane $\mathrm{PG}(2,q^{2})$ to produce one-factorisations of the complete graph $K_{q(q-1)}$.
Streaming@Twitter

Twitter generates tens of billions of events per hour when users interact with it. Analyzing these events to surface relevant content and to derive insights in real-time is a challenge. To address this, we developed Heron, a new real time distributed streaming engine. In this paper, we first describe the design goals of Heron and show how the Heron architecture achieves task isolation and resource reservation to ease debugging, troubleshooting, and seamless use of shared cluster infrastructure with other critical Twitter services. We subsequently explore how a topology self adjusts using back pressure so that the pace of the topology goes as its slowest component. Finally, we outline how Heron implements at-mostonce and at-least-once semantics and we describe a few operational stories based on running Heron in production.
Synthesizing Character Animation with Smoothly Decomposed Motion Layers

The processing of captured motion is an essential task for undertaking the synthesis of high‐quality character animation. The motion decomposition techniques investigated in prior work extract meaningful motion primitives that help to facilitate this process. Carefully selected motion primitives can play a major role in various motion‐synthesis tasks, such as interpolation, blending, warping, editing or the generation of new motions. Unfortunately, for a complex character motion, finding generic motion primitives by decomposition is an intractable problem due to the compound nature of the behaviours of such characters. Additionally, decomposed motion primitives tend to be too limited for the chosen model to cover a broad range of motion‐synthesis tasks. To address these challenges, we propose a generative motion decomposition framework in which the decomposed motion primitives are applicable to a wide range of motion‐synthesis tasks. Technically, the input motion is smoothly decomposed into three motion layers. These are base‐level motion, a layer with controllable motion displacements and a layer with high‐frequency residuals. The final motion can easily be synthesized simply by changing a single user parameter that is linked to the layer of controllable motion displacements or by imposing suitable temporal correspondences to the decomposition framework. Our experiments show that this decomposition provides a great deal of flexibility in several motion synthesis scenarios: denoising, style modulation, upsampling and time warping.
Group Connectivity and Group Coloring: Small Groups versus Large Groups

A well-known result of Tutte says that if $\Gamma$ is an Abelian group and $G$ is a graph having a nowhere-zero $\Gamma$-flow, then $G$ has a nowhere-zero $\Gamma'$-flow for each Abelian group $\Gamma'$ whose order is at least the order of $\Gamma$. Jaeger, Linial, Payan, and Tarsi observed that this does not extend to their more general concept of group connectivity. Motivated by this we define $g(k)$ as the least number such that, if $G$ is $\Gamma$-connected for some Abelian group $\Gamma$ of order $k$, then $G$ is also $\Gamma'$-connected for every Abelian group $\Gamma'$ of order $|\Gamma'| \geqslant g(k)$. We prove that $g(k)$ exists and satisfies for infinitely many $k$, \begin{align*}(2-o(1)) k < g(k) \leqslant 8k^3+1. \end{align*} The upper bound holds for all $k$. Analogously, we define $h(k)$ as the least number such that, if $G$ is $\Gamma$-colorable for some Abelian group $\Gamma$ of order $k$, then $G$ is also $\Gamma'$-colorable for every Abelian group $\Gamma'$ of order $|\Gamma'| \geq h(k)$. Then $h(k)$ exists and satisfies for infinitely many $k$, \begin{align*}(2-o(1)) k < h(k) < (2+o(1))k \ln(k). \end{align*} The upper bound (for all $k$) follows from a result of Král', Pangrác, and Voss. The lower bound follows by duality from our lower bound on $g(k)$ as that bound is demonstrated by planar graphs.

This study aims to examine social network sites acceptance in an e-Learning system and to propose a model encompassing determining factors that affect students’ intentions to use social network sites in the e-Learning system. The proposed model was built based on the Technology Acceptance Model (TAM), perceived enjoyment, social influences, and perceived information security from the literature review. The quantitative method of data collection using a questionnaire survey is used in the current study. The data analysed using a structural equation modeling (SEM) approach through partial least square (PLS) software version 3. The results indicated that perceived ease of use, perceived usefulness, perceived enjoyment, social influences, and perceived information security has a significant and positive impact on student’s acceptance of social network sites in an e-Learning system at Palestine Technical University-Kadoorie. Theoretical and practical implications discussed.
Gold Nanoparticles in Liquid Based on Photonic Crystal Fiber PCF for Sensors Application

The effect of laser wavelength on gold nanoparticle (Au NPs) fabrication is reported by using the laser ablation in the liquid method in the ethanol. The Pulsed Laser ablation in liquid technique of the gold target was ablated using an Nd:YAG laser nanopulsed nanosecond after that the investigation of the gold NPs was tested by the AFM (Atomic Force Microscopy), and the (XRD) X-ray diffraction. The results showed the characteristics of prepared NPs, depending on XRD, AFM. NPs obtained by 532 nm laser possess better properties than that achieved by 1064 nm laser according to the highest intensity of shorter wavelengths.

Governance structures and relational contracting in local public services: a comparison of French and American public-private partnerships

This paper compares public-private partnerships (PPPs) implemented both in France and in the U.S. This contribution to the study of local public services uses an original theoretical framework, inspired by a synthesized version of several theories of the firm proposed by Baker, Gibbons and Murphy [2004]. Comparison is established both on legal and informal levels. This allows us to show (i) to what extent legal frameworks influence the efficiency of public-private partnerships, (ii) how relational environment matters in the success of such agreements, and (iii) that an achieved equilibrium may appear as relative to the context, in which such contracts are implemented. The conclusions of this model participate to the current debates about a possible harmonization of European legislation in PPPs, and about the promotion of public-private partnerships observed in some countries in other institutional frameworks.

Aiming at solving ontology heterogeneity, in this paper, we propose approaches of ontological concept mapping based on multi-strategy. At first, we use strategies based on concept name, property and taxonomy to calculate similarity. Then mapping results of multi-strategy are obtained. Finally, we present experimental results with high accuracy and point out future research directions.
Smooth Particle Hydrodynamic and URAN Visualization of Multiphase Flow

Significant research is being conducted in the simulation of fluid flows due to the increase in employing the physics of the fluid flow to either commercial, in-house or open source codes. The analysis of the fluid flow is mainly based on the Lagrangian or the Eulerian approach. Many of the simulation codes employ the Eulerian approach due to its simplicity. These codes are based on several numerical techniques and yet few benchmarks have been conducted. However, the codes which employ the Lagrangian approach seem to be promising and may accurately simulate fluid flow phenomena. In this paper, a comparative analysis of the Lagrangian and Eulerian approach is investigated for a water droplet in a tank. The velocity field and the total pressure of the fluid are generated for the simulation by employing Ansys Fluent for the Eulerian approach and DualPhysics for the Lagrangian approach. The fluid structure and the fluid flow development are compared in order to assess the capability of each approaches in analysing the investigated fluid flow. This study may play a significant role on the importance of employing the Lagrangian approach for fluid flows where complex fluid structure occurs.
Pixel-based Character Image Compression for Data Transfer from ARM Controller to FPGA System

This paper proposes a pixel-based compression algorithm for character digital image in improving the storage of characters in memory during system operation. In particular, in this algorithm, each character binary image in text is grouped by binary numbers and then encoded to reduce the character image capacity of the character compared to the original character. In addition, a novel point in this algorithm is that one character image type is differently grouped binary numbers for compressing. Therefore, the compressed character image is stored in a memory using an ARM microcontroller system and transferred to an FPGA module for decoding before printing. Moreover, the compression ratio of each character is high or low depending on the font type of image characters. Therefore, the high compression ratio using this compression algorithm will allow saving memory space in the memory system. Simulation results show to illustrate the effectiveness of the proposed algorithm and also this compression algorithm was implemented to texts with characters for encoder data transfer from an ARM microcontroller into an FPGA system for effectively printing the text/logo/barcode/QR code/expired date on products with high speed after decoding. Moreover, this compression algorithm can be developed to apply to many different font types and sizes, as well as be utilized different microcontrollers/Microprocessors connected to FPGA systems for processing with high speed. It means that one industrial system using this algorithm can obtain very high performance related to processing digital image characters.

Background: Medicinal plants (MP) are the primary source of health care in developing countries like Nepal. Specially, indigenous people depend on MP species for their basic livelihood. In this study, we aimed to document MP species and assess their indigenous use among Magar (Kham) community in Western Nepal. Methods: A list of MP species was prepared through empirical ethnobotanical study and their indigenous use was assessed using a set of questionnaires. The data collected was generalized for MP species diversity, use categories, and life forms. Informant consensus factor (Fic), Use Frequency (UF) and Use Value (UV) were used to find the cultural importance of MP species. Results: We recorded 82 MP species, belonging to 45 families and 75 genera of which nine species cited in Magar (Kham) community are ethnobotanically new to Nepal. Informant consensus factor value was found to be high (1) for eight ailment categories; cancer, warts, pneumonia, dandruff, frightening, anesthetic, skin disease, eye irritation and leeches. Based on use value index, the most important ethnomedicinal species were Bergenia ciliata, Swertia chirayta, Acorus calamus and Aconitum gammiei. Conclusions: This study provides complete document of indigenous uses of MP species among Magar (Kham) community of Thabang Rural Municipality (RM), Rolpa district. Nine MP species were reported with new uses for the first time in Nepal. There is further possibility of recording of new use reports in other villages adjoining to the present studied Magar Kham community. The species with high cultural values must be tested further for their pharmacological properties.
Evaluation and Analysis of Different Types of Prosthetic Knee Joint Used by above Knee Amputee

Four prosthetic knee joints (polycentric knee weight activating-4bar and friction, extension assist controlled),(single axis knee weight activating and friction, internal extension assist controlled), (single axis knee weight activating-4bar and hydraulically, controlled) and (polycentric knee geometric locking-6bar, hydraulically controlled) for a trans-femoral patient were tested. The tests were conducted to find the maximum velocity as well as discussing the most comfortable prosthetic forthe patient and walking stability for these prosthetic knees by examining the gait cycle and measuring the ground reaction force (GRF), using force a plate device. Also, the interface pressure was measured between socket and stump muscles by using F-socket device to get the stress distribution during walking with a prosthetic knee. Results manifested that the polycentric knee geometric locking - 6bar, hydraulically controlled is the best because of the good homogenous distribution of GRF between the healthy and prosthetic limb, during which the difference between both the healthy and prosthetic limb is with the least value (4%). And, K4 gives the minimum value of differences in contact pressure between the left and right limb with a value of (24%), it alsoimparts the maximum symmetry between the left and right limb according to the gait cycle parameters.The best results of the interface pressures and kinovea velocity are achieved whenK4 is used with (132.4KPa, 0.71m/s), respectively. Finally, the polycentric knee geometric locking - 6bar, hydraulically controlled is the best according to the ANSYS results during which it yields the minimum values of Von-Mises stress with 14.24MPa and a maximum factor of safety of 3.11.
