New data on critical holdups of dispersed phase were measured at which the phase inversion took place. The systems studied differed in the ratio of phase viscosities and interfacial tension. A weak dependence was found of critical holdups on the impeller revolutions and on the material contactor; on the contrary, a considerable effect of viscosity was found out as far as the viscosity of continuous phase exceeded that of dispersed phase.

As it is appreciated that learning is a non-linear process – implying that coaching methodologies in sport should be accommodative – it is reasonable to suggest that player development pathways should also account for this non-linearity. A constraints-led approach (CLA), predicated on the theory of ecological dynamics, has been suggested as a viable framework for capturing the non-linearity of learning, development and performance in sport. The CLA articulates how skills emerge through the interaction of different constraints (task-environment-performer). However, despite its well-established theoretical roots, there are challenges to implementing it in practice. Accordingly, to help practitioners navigate such challenges, this paper proposes a user-friendly framework that demonstrates the benefits of a CLA. Specifically, to conceptualize the non-linear and individualized nature of learning, and how it can inform player development, we apply Adolph’s notion of learning IN development to explain the fundamental ideas of a CLA. We then exemplify a learning IN development framework, based on a CLA, brought to life in a high-level youth football organization. We contend that this framework can provide a novel approach for presenting the key ideas of a CLA and its powerful pedagogic concepts to practitioners at all levels, informing coach education programs, player development frameworks and learning environment designs in sport.

The Impact

AbstractThe high-speed impact of a droplet onto a flexible substrate is a highly non-linear process of practical importance, which poses formidable modelling challenges in the context of fluid–structure interaction. We present two approaches aimed at investigating the canonical system of a droplet impacting onto a rigid plate supported by a spring and a dashpot: matched asymptotic expansions and direct numerical simulation (DNS). In the former, we derive a generalisation of inviscid Wagner theory to approximate the flow behaviour during the early stages of the impact. In the latter, we perform detailed DNS designed to validate the analytical framework, as well as provide insight into later times beyond the reach of the proposed analytical model. Drawing from both methods, we observe the strong influence that the mass of the plate, resistance of the dashpot, and stiffness of the spring have on the motion of the solid, which undergo forced damped oscillations. Furthermore, we examine how the plate motion affects the dynamics of the droplet, predominantly through altering its internal hydrodynamic pressure distribution. We build on the interplay between these techniques, demonstrating that a hybrid approach leads to improved model and computational development, as well as result interpretation, across multiple length and time scales.

In recent years, there has been a proliferation of programs aimed at preventing radicalization and disengaging known violent extremists. Some programs have targeted individuals through the use of case management approaches and the development of individual intervention plans (e.g., the Desistance and Disengagement Program and the Channel program in the UK; the Australian New South Wales Corrections Proactive Integrated Support Model—PRISM—and state-based division initiatives in Australia). There is a broad consensus in the literature that the evaluation of such initiatives has been neglected. However, the evaluation of case-managed interventions to counter violent extremism (CVE) is challenging. They can have small caseloads which makes it difficult to have any comparison or control group. Client participation can vary over time, with no single intervention plan being alike. This can make it hard to untangle the relative influence of different components of the intervention on indicators of radicalization and disengagement. In this presentation, results from primary research that set out to evaluate case-managed CVE interventions in Australia and develop evaluation metrics are presented. This research involves the examination of interventions implemented by New South Wales corrections and state police. The effectiveness of these interventions was assessed against a five-point metric of client change. Client change overtime was analyzed using case note information collected by the various interventions on client participation. Results show that client change is not a linear process and that the longer an individual is engaged in a case-managed intervention, the more likely they are to demonstrate change relating to disengagement. Specific case studies are used to illustrate trajectories and turning points related to radicalization and to highlight the role of case-managed interventions in facilitating disengagement. Key elements of effective interventions include the provision of ongoing informal support. Investment in capturing case note information should be a priority of intervention providers. Different challenges confronted by case-managed CVE interventions are highlighted.

Perinatal psychological distress (PPD) may cause delays in help-seeking in the perinatal period, which is crucial for families with small children. Help-seeking theories focus on rational processes of behavior wherein ‘help-seeking’ is viewed as a decision-making process, in which action is preceded by recognizing a problem. We identified the phase prior to actual help-seeking actions as a life situation and a phenomenon through which to gain a deeper understanding from women’s own perspectives. The aim of this study was to integrate and synthesize knowledge of women’s experiences of contemplating seeking help for PPD. We chose interpretative meta-ethnography by Noblit and Hare (1988) and implemented eMERGe guidelines in reporting. The search was performed systematically, and the 14 included studies were evaluated with Critical Appraisal Skills Programme checklist (CASP). We identified seven themes and a metaphor in a lines-of-argument synthesis, showing that contemplating help-seeking is a multidimensional phenomenon. We did not observe a straightforward and linear process (as previous research suggests) but instead a complex process of contemplating help-seeking. A clinical implication is that service providers should work with outreach and develop their tools to connect with mothers with PPD. Another suggestion is to improve training in mental health literacy prior to or during pregnancy.

The product concept is crucial in new product development (NPD) because it represents an NPD project’s goal. In this context, most prior studies have regarded product concept development as a linear process but some recent studies have revealed that it also has nonlinear characteristics. The objective of this paper is to explore why this inconsistency has arisen and to develop a model and theory that illustrate both aspects of product concept development. To achieve this, we adopt the perspective of organisational interpretation systems (Daft and Weick (1984). Toward a model of organisations as interpretation systems. Academy of Management Review, 9(2), 289–295) and explore eight product development cases. Consequently, we develop a three-stage model and find that the linearity or nonlinearity of product concept development is determined by each NPD team’s assumption about the environment. We also consider product innovativeness and function equivocality, and establish that these are related to the NPD teams’ assumptions about the environment.
