Fathers’ role in sustainability of exclusive breastfeeding practice in post-cesarean-section mothers

Background: The success of breastfeeding among post-cesarean-section mothers requires strong willingness and commitment, self-confidence, support from various professionals, and internal support (especially from their husband) and the belief and value of their family. Exclusive breastfeeding remains low in some cities such as in West Java, especially in post-cesarean-section mothers, who are influenced by certain factors. The purpose of this study is to identify husbands’ role and their support for post-cesarean-section mothers in exclusive breastfeeding.Design and Methods: This study used a qualitative phenomenological approach. with a combination of different data collection techniques: focus group discussion and in-depth interviews. Twelve husbands of post-cesarean-section mothers participated in this study. Data were analyzed by thematic content analysis.Results: Four themes were identified namely knowledge about exclusive breastfeeding, the role of the father during breastfeeding, the experience of the husband and the family in supporting breastfeeding, and Women’s lack of knowledge, inconvenience due to pain as the most impending factors of exclusive breastfeeding.Conclusion: Most fathers seem eager to be involved and assist their partners to give breastfeeding to their baby. Furthermore, adequate support from family members, health care professionals, and employers can enable fathers to encourage and help their partners initiate and maintain exclusive breastfeeding. Fathers’ emotional, practical, and physical supports are also important factors that promote successful breastfeeding and enrich the experience of mothers.

THE VALUE OF EXPERIENCE-BASED SIMULATION IN GARNERING SUPPORT FOR RADICALLY NEW CONCEPTS

Radically new concepts (RNCs) are often killed off early in the new product development (NPD) process because they do not get the required support, such as financial resources from senior managers or input from technical experts. One reason is that the potential value of fledgling RNCs is often difficult for internal audiences to imagine when evaluating them. Our experimental study with 125 RNC evaluators investigates how experience-based simulation may increase their imaginative capability and support for an RNC. It increases imaginative capability in evaluators with positive preconceptions of RNCs (i.e., low cognitive resistance), thus strengthening their support. However, those with negative preconceptions (high cognitive resistance) become less supportive of RNCs in an experience-based simulation than in other settings. We draw from information-processing and construal level theory to explain the positive and negative effects of experience-based simulation. We also provide suggestions for NPD practitioners seeking internal support to progress their RNCs.

A model of an inflatable elastic aerofoil

A novel method is presented to calculate the deformation of a simple elastic aerofoil with a view to determining its aerodynamic viability. The aerofoil is modelled as a thin two-dimensional elastic sheet whose ends are joined together to form a corner of prescribed angle, with a simple support included to constrain the shape to resemble that of a classical aerofoil. The weight of the aerofoil is counterbalanced exactly by the lift force due to a circulation set according to the Kutta condition. An iterative process based on a boundary integral method is used to compute the deformation of the aerofoil in response to an inviscid fluid flow, and a range of flow speeds is determined for which the aerofoil maintains an aerodynamic shape. As the flow speed is increased the aerofoil deforms significantly around its trailing edge, resulting in a negative camber and a loss of lift. The loss of lift is ameliorated by increasing the inflation pressure but at the expense of an increase in drag as the aerofoil bulges into a less aerodynamic shape. Boundary layer calculations and nonlinear unsteady viscous simulations are used to analyse the aerodynamic characteristics of the deformed aerofoil in a viscous flow. By tailoring the internal support the viscous boundary layer separation can be delayed and the lift-to-drag ratio of the aerofoil can be substantially increased.

A Case Study on the Deformation of Metro Foundation Pit in Silt Stratum in North China

Geological conditions of urban subway foundation pits are controllable factors in determining the deformation of pits. In this paper, the monitoring data and statistical data of a subway deep foundation pit in North China are presented and compared with those of Tianjin subway. The deformation characteristics of the proposed pit, open excavated with triple-layer steel supports, are introduced in detail. Based on the aforementioned information, the energy conservation equation of the mobilized strength design (MSD) method in which the compression deformation energy of internal support is considered is applied to predict the maximum lateral movement. The maximum lateral movement turns out to be 22.2 mm according to the improved MSD method, which is very close to the measured value.

Hospital-based violence intervention: strategies for cultivating internal support, community partnerships, and strengthening practitioner engagement

Purpose The purpose of this paper is to present strategies for cultivating internal support, community partnerships and practitioner engagement for Hospital-based Violence Intervention Programs (HVIPs). In response to growing concerns about community violence and calls to engage the community in its solutions, HVIPs have increased in popularity as innovative and transdisciplinary approaches to violence intervention. HVIPs are one strategy under the broad purview of public health approaches to crime and violence – focusing on reaching recent victims of violence in emergency departments and leveraging this “teachable moment” to offer wrap-around services geared toward preventing future violence or revictimization. Design/methodology/approach This paper uses an autoethnographic and case study approach of Project HEAL (Help, Empower and Lead), a newly established HVIP at Jersey Shore University Medical Center. Findings While there is no “standard” approach, the importance of strong community partnerships and practitioner engagement prior to and during the HVIP implementation process is second to none. Research limitations/implications This case study of Project HEAL’s initial implementation will provide information that can assist other HVIPs in creating and sustaining necessary internal support, community partnerships and practitioner engagement, and potentially help navigate forthcoming statewide and federal efforts. Originality/value Development of meaningful community partnerships and achievement of a high level of engagement from practitioners are key to the successful implementation of HVIPs, the processes of which are not always documented in literature.

Topology Optimization for Additively Manufactured Self-Supporting Axisymmetric Structures

This paper discusses the design of axisymmetric structures with self-supporting features that can be additively manufactured without requiring internal support structures. This is motivated by wire-fed additive manufacturing processes, many of which can fabricate designs with enclosed pores that inherently exist in many axisymmetric structures, such as double walled pressure vessels. Although enclosed pores are possible, features that rise at shallow angles from the build plate typically cannot be fabricated without the use of support structures, which require removal and thus are unfavorable in such applications. In this paper, an overhang constraint is applied to ensure that all designed features rise at a designer-prescribed self-supporting angle to eliminate the need for such support structures. This is achieved by coupling the projection-based overhang constraint approach with topology optimization and axisymmetric finite elements whose stiffness is interpolated using Solid Isotropic Material with Penalization (SIMP). Gradients are computed with the adjoint method and the Method of Moving Asymptotes (MMA) is employed as the gradient-based optimizer. Two numerical examples related to a canonical pressure vessel and an optical mirror support structure are used to demonstrate the approach. Solutions are shown to satisfy minimum feature size requirements and designer-prescribed (process dependent) overhang constraint angles, while providing clear and crisp representations of topology. As observed in past works on overhang constraints, a clear trade-off is illustrated between the magnitude of the overhang constraint angle and the structural performance (mass or stiffness), with more strict requirements producing designs with lower performance.

Mechanical analysis of enhancement in tensile performance of thin-walled circular tubes by internal support

Fillers can improve the tensile performance of ductile tubes. Mechanical analyses of tensile tubes with filler have generally focused on experimental and numerical studies on concrete-filled steel tube (CFST) components, while mechanical performance of tensile tubes with flexible supporting fillers has rarely been investigated. In the current research, we have proposed a “steel tube+pre-stressed flexible internal support” structure. Meanwhile, strengthening of tensile thin-walled tubes with internal supports was studied in terms of stress and deformation. The trends of yield strength and ultimate strength of tensile tubes were determined and calculation equations of yield strength and normal ultimate strength of tensile tubes with internal support were derived. Strengthening coefficient variations as functions of radius-thickness ratios of steel tubes and elastic moduli of internal supports as well the optimized internal support p corresponding to maximum increment of tensile performance of tubes were also determined. It was experimentally verified that the initial supporting pre-stress of internal support on steel tubes could be achieved by cold shrink fitting technique. Experimental results revealed that the developed composite structure significantly enhanced the mechanical performance, fracture toughness, and energy consumption characteristics of tensile tubes. Hence, the proposed structure was confirmed to have promising applications.
