Published: May 2018

Abstract
Sea-effect snowstorms generated over the Sea of Japan produce consistent and often heavy snowfall throughout the winter season, impacting downstream communities in northern and central Japan. Here, we use observations and Weather Research and Forecasting (WRF) Model simulations to examine the precipitation distribution produced by transverse-mode sea-effect snowbands that interacted with the mountainous terrain circumscribing Ishikari Bay, Hokkaido Island, Japan, on 12 January 2014. The bands observed here were horizontal convective rolls aligned normal to the mean flow and were ~10 km wide and up to ~100 km long. The bands approached Ishikari Bay at intervals of ~10–16 min, intensifying as they progressed through a quasi-stationary, elongated enhancement region that paralleled the Shakotan Peninsula and extended into the Ishikari plain. Hydrometeor advection, through an ascent region over the northeast slope of the Shakotan Peninsula, and along clockwise-turning trajectories steered by the boundary layer directional shear, contributed to sustained precipitation enhancement along a curve in the elongated enhancement region near the entrance to Ishikari Bay. Downstream, orographic flow deflection by the coastal mountains, likely accentuated by thermal and roughness gradients along the Shakotan Peninsula’s shoreline, produced convergence and ascent along the elongated enhancement region. This study demonstrates the impact of downstream topography on sea-effect snowstorms and has implications for improving the prediction of snowfall in this and other lake- and sea-effect regions.
Between Academia and Civil Society: The Origins of Latin American Studies in the Netherlands
Authors: Baud Michiel 
Published: May 2018

Dutch Latin American studies as a field of academic teaching and research emerged in the late 1960s and became consolidated in the 1970s and 1980s. It began as a purely academic endeavor, but in a changing Dutch and global society in the 1970s it rapidly became connected to and influenced by social and political processes in Latin America. The strong Christian and social-democratic traditions in the Netherlands allowed for strong links between academic researchers and civil society organizations. This resulted in the productive coexistence of academic and more political objectives and activities and allowed Dutch Latin American studies to grow into a dynamic field. A review of this experience calls attention to the importance of local conditions for understanding the consequences of the Cold War for academic research. Los estudios holandeses sobre Latinoamérica emergieron como un campo de investigación y enseñanza académica a finales de la década de 1960, consolidándose durante los setenta y ochenta. Comenzaron como una actividad puramente académica, pero en la cambiante sociedad holandesa y global de los años setenta, rápidamente se vincularon a y fueron influenciados por los procesos políticos y sociales de América Latina. La fuerte tradición cristiana y social-democrática de Holanda dio lugar a poderosos vínculos entre investigadores académicos y organizaciones civiles. Esto llevó a la coexistencia de metas y actividades académicas al igual que aquellas de índole más política, transformando a los estudios holandeses sobre Latinoamérica en un campo dinámico. Un vistazo a esta experiencia resalta la importancia de las condiciones locales para una debida comprensión de las consecuencias de la Guerra Fría en la investigación académica.

Introduction This study aimed to explore the experience of staff and residents of mental health residential care facilities, using iPads as a medium to engage in meaningful occupation. Method A mixed method was used, which combined descriptive quantitative and thematic qualitative analysis. The Pan Occupational Paradigm was used as a theoretical framework, to maintain an occupational perspective. Residents participated in semi-structured interviews, and staff completed surveys and participated in a focus group or individual interview. The responses were then coded and analysed for their description of ‘doing’, ‘being’, ‘becoming’ and ‘belonging’ experiences. Findings Analysis found that residents engaged in personally meaningful occupations with the iPads, often with staff facilitation. The study also found that staff and residents responded positively to the iPads, particularly regarding developing positive connections and opportunities for growth and mastery. However, barriers associated with resource availability (particularly hardware and infrastructure) were also identified. Conclusion The use of iPads in these facilities provided opportunities for residents to engage in meaningful occupation, and overcome the occupational limitations inherent in the service setting. iPad use also enabled residents to engage in the community outside the facility.
An oral history of occupational therapy education in the Republic of Ireland
Authors: Dunne Bríd D , Pettigrew Judith , Robinson Katie 
Published: May 2018

Introduction Historical research contributes to the critical perspectives called for in occupational therapy. Despite this, research on the history of occupational therapy education is limited. The only occupational therapy programme in the Republic of Ireland from 1963 to 1986 was the diploma at St Joseph's College of Occupational Therapy, Dublin, which followed the curriculum first of the Association of Occupational Therapists and from 1974 the British Association of Occupational Therapists. This study explores oral histories of pioneering students from that programme. Method Oral history interviews were conducted with 19 former students of the programme who studied between 1963 and 1970. Interviews were thematically analysed. Findings Participants described a curriculum with two subject foci: academic and activity-based subjects. Despite a focus on activity-based subjects in the curriculum, participants were ambivalent about their use in practice. They described a need to manage tensions arising from working alongside craft workers designated as occupational therapists. Throughout the interviews, claims for the professional status of occupational therapy were identified. Conclusion The oral histories reveal a multitude of professionalisation strategies used to establish the profession in 1960s and 1970s Ireland. These findings have relevance for present day debates about professionalisation, occupation-focused curricula and interprofessional practice and education.
Determinants of the Global Prices of Ready-to-Use Therapeutic Foods
Authors: Kakietek Jakub 
Published: May 2018

Background: A therapy based on ready-to-use therapeutic food (RUTF) in outpatient settings is considered the gold standard in the treatment of severe acute malnutrition in children younger than 5 years. The price of RUTF is the key cost driver of the therapy. However, no studies to date have systematically examined the determinants of RUTF prices. Objective: This article presents the first analysis of factors associated with the prices of RUTF, focusing on the impact of competition and tendering. Methods: This article examines data on the prices of RUTF purchased by UNICEF Supply Division from 2006 through 2015 (90% of RUTF purchased globally). To assess the association between price, competition, and tender introduction, controlling for potential confounding factors, regression analysis using a generalized estimating equation was used. Results: Competition, measured as the number of suppliers, was negatively associated with RUTF price. On the other hand, no statistically significant association was found between RUTF price tendering. Quantities sold were also significantly associated with RUTF prices. Conclusions: Significant price reductions have been achieved by increasing competition in the RUTF market. In contrast, introduction of tendering did not result in decreases in prices. Tendering is an effective price-lowering mechanism because it awards the bidder(s) with the lowest price with market exclusivity. However, the current tender system promotes market fragmentation and reduces the incentives for price reductions. Further reduction in RUTF prices can likely be achieved by modifying the current tendering procedures and putting a greater emphasis on price competition.
Leniency, Status and Output Informativeness
Authors: Dey Oindrila 
Published: May 2018

The article identifies the condition under which it is beneficial for the principal to be a lenient performance evaluator towards his/her favourite agent. It provides the game theoretic foundation behind the decision of choosing leniency (biased) over stringency (fair). The emergence of an influential literature captures the different aspects of status as a non-monetary incentive and its significance in organisational theory. However, the interplay between status and evaluation system has not been studied much. The article is built over an article by Dey and Banerjee (2014a) to understand the role of status incentive with the leniency of evaluation. Analysis of the interplay between status and leniency shows that when status is valued more, the principal benefits from this form of biasness. Interestingly, this article also provides a linkage between informativeness of output signal with this form of biasness. Using moral hazard framework with limited liability in a discrete effort framework, it is suggested that a weak output signal can act as an instrument in reducing the emergence of a lenient evaluation.

SummaryBob Spitzer died in December 2015 but is not likely to be forgotten quickly. His Herculean task in reforming psychiatric diagnosis, mainly by the development of the third edition of the Diagnostic and Statistical Manual of Mental Disorders in 1980, has been acknowledged by many, but it remains unfinished. To complete the process, we need more than good diagnostic reliability, we need better veracity.Declaration of interestNone.

Trade-in Remanufacturing, Customer Purchasing Behavior, and Government Policy
Authors: Zhang Fuqiang , Zhang Renyu 
Published: May 2018

Trade-in remanufacturing is a commonly adopted business practice under which firms collect used products for remanufacturing by allowing repeat customers to trade in used products for upgraded ones at a discount price. This paper studies how customer purchasing behavior and remanufacturing efficiency affect the economic and environmental values of such a business practice. We demonstrate a new benefit of trade-in remanufacturing: it helps exploit the forward-looking behavior of strategic customers, which could be much more significant than the widely recognized revenue-generating and environmental benefits of remanufacturing. High remanufacturing efficiency does not necessarily benefit a firm. With overly high remanufacturing efficiency, product durability is so high that repeat customers are reluctant to trade in and upgrade their used products. When customers are highly strategic, trade-in remanufacturing creates a tension between profitability and sustainability: on one hand, by exploiting the intensive forward-looking customer behavior, trade-in remanufacturing is quite valuable to the firm; on the other hand, with highly strategic customers, trade-in remanufacturing has a substantial negative impact on the environment and social welfare, since it may induce significantly higher production quantities without improving customer surplus. With nearly myopic customers, however, trade-in remanufacturing benefits both the firm and the environment. Therefore, understanding the interactions between customer purchasing behavior and trade-in remanufacturing is important to both firms and policy makers. Finally, to resolve the above tension, we study how a social planner (e.g., government) should design a public policy to maximize social welfare. The social optimum can be achieved by using a simple linear subsidy/tax scheme for both new production and remanufacturing. The proposed policy can also induce the firm to set the socially optimal remanufacturing efficiency. The online appendix is available at https://doi.org/10.1287/msom.2017.0696 .
Statistical Learning in Tree-Based Tensor Format
Authors: Grelier Erwan , Chevreuil Mathilde , Nouy Anthony 
Published: May 2018

Tensor methods are widely used tools for the approximation of high dimensional functions. Such problems are encountered in uncertainty quantification and statistical learning, where the high dimensionality imposes to use specific techniques, such as rank-structured approximations [1].
In this work, we introduce a statistical learning algorithm for the approximation in tree-based tensor format, which are tensor networks whose graphs are dimension partition trees. This tensor format includes the Tucker format, the Tensor-Train format, as well as the more general Hierarchical tensor formats [4]. It can be interpreted as a deep neural network with a particular architecture [2].
The proposed algorithm uses random evaluations of a function to provide a tree-based tensor approximation, with adaptation of the tree-based rank by using a heuristic criterion based on the higher-order singular values to select the ranks to increase, and of the approximation spaces of the leaves of the tree.
We then present a learning algorithm for the approximation under the form u(x) ≈ v(z_1,...,z_m) where v is a tensor in tree-based format and the z_i = g_i(x), 1 ≤ i ≤ m, are new variables. A strategy based on the projection pursuit regression [3] is proposed to compute the mappings g_i and increase the effective dimension m.
The methods are illustrated on different examples to show their efficiency and adaptability as well as the power of representation of the tree-based tensor format, possibly combined with changes of variables.
Fast Solution of the Nonlinear Poisson-Boltzmann Equation Using the Reduced Basis Method and Range-Separated Tensor Format
Authors: Kweyu Cleophas , Feng Lihong , Stein Matthias , Benner Peter 
Published: May 2018

The Poisson-Boltzmann equation (PBE) is a nonlinear elliptic parametrized partial differential equation that is ubiquitous in biomolecular modeling. It determines a dimensionless electrostatic potential around a biomolecule immersed in an ionic solution \cite{Chen}. For a monovalent electrolyte (i.e. a symmetric 1:1 ionic solution) it is given by
$$\label{PBE} -\vec{\nabla}.(\epsilon(x)\vec{\nabla}u(x)) + \bar{\kappa}^2(x) \sinh(u(x)) = \frac{4\pi e^2}{k_B T}\sum_{i=1}^{N_m}z_i\delta(x-x_i) \quad \textrm{in} \quad \Omega \in \mathbb{R}^3, $$

$$\label{eq:Dirichlet} u(x) = g(x) \quad \textrm{on} \quad \partial{\Omega}, $$
where
$\epsilon(x)$
and
$\bar{k}^2(x)$
are discontinuous functions at the interface between the charged biomolecule and the solvent, respectively.
$\delta(x-x_i)$
is the Dirac delta distribution at point
$x_i$
. In this study, we treat the PBE as an interface problem by employing the recently developed range-separated tensor format as a solution decomposition technique \cite{BKK_RS:16}. This is aimed at separating efficiently the singular part of the solution, which is associated with
$\delta(x-x_i)$
, from the regular (or smooth) part. It avoids building numerical approximations to the highly singular part because its analytical solution, in the form of
$u_{\textrm{s}}(x) = \alpha \sum_{i=1}^{Nm}z_i/ \lvert x-x_i \rvert$
exists, hence increasing the overall accuracy of the PBE solution.\\
On the other hand, numerical computation of \eqref{PBE} yields a high-fidelity full order model (FOM) with dimension of
$\mathcal{O}(10^5)$

$\sim$

$\mathcal{O}(10^6)$
, which is computationally expensive to solve on modern computer architectures for parameters with varying values, for example, the ionic strength,
$I \in \bar{k}^2(x)$
. Reduced basis methods are able to circumvent this issue by constructing a highly accurate yet small-sized reduced order model (ROM) which inherits all of the parametric properties of the original FOM \cite{morRozHP08}. This greatly reduces the computational complexity of the system, thereby enabling fast simulations in a many-query context. We show numerical results where the RBM reduces the model order by a factor of approximately $350,000$ and computational time by $7,000$ at an accuracy of
$\mathcal{O}(10^{-8})$
. This shows the potential of the RBM to be incorporated in the available software packages, for example, the adaptive Poisson-Boltzmann software (APBS).
POD-Galerkin reduced order methods for inverse and multi-physics problems in fluid dynamics
Authors: Nonino Monica , Strazzullo Maria , Zainib Zakia , Ballarin Francesco , Rozza Gianluigi 
Published: May 2018

In this work we will focus on recent advances in reduced order modelling for parametrized problems in computational fluid dynamics, with a special attention to the case of inverse problems, such as optimal flow control problems and data assimilation, and multi-physics applications.
Among the former, we will discuss applications arising in environmental marine sciences and engineering, namely a pollutant control in the Gulf of Trieste, Italy and a solution tracking governed by quasi-geostrophic equations describing North Atlantic Ocean dynamic. Similar methodologies will also be employed in problems related to the modeling of the cardiovascular system.
Among the latter, we will present further recent developments on reduction of fluid-structure interaction problems, based on our earlier work. Reduced order approaches for parametric optimal flow control will also be applied in combination with domain decomposition in view of further applications in multi-physics.

SVD on Intersection Spaces
Authors: Ali Mazen , Nouy Anthony 
Published: May 2018

We are interested in applying SVD to more general spaces, the motivating example being the Sobolev space
$H^1(\Omega)$
of weakly differentiable functions over a domain
$\Omega\subset\R^d$
. Controlling the truncation error in the energy norm is particularly interesting for PDE applications. To this end, one can apply SVD to tensor products in
$H^1(\Omega_1)\otimes H^1(\Omega_2)$
with the induced tensor scalar product. However, the resulting space is not
$H^1(\Omega_1\times\Omega_2)$
but is instead the space
$H^1_{\text{mix}}(\Omega_1\times\Omega_2)$
of functions with mixed regularity. For large
$d>2$
this poses a restrictive regularity requirement on
$u\in H^1(\Omega)$
. On the other hand, the space
$H^1(\Omega)$
is not a tensor product Hilbert space, in particular
$\|\cdot\|_{H^1}$
is not a reasonable crossnorm. Thus, we can not identify
$H^1(\Omega)$
with the space of Hilbert Schmidt operators and apply SVD.
However, it is known that
$H^1(\Omega)$
is isomorph (here written for
$d=2$
) to the Banach intersection space
$$H^1(\Omega_1\times\Omega_2)=H^1(\Omega_1)\otimes L_2(\Omega_2)\cap L_2(\Omega_1)\otimes H^1(\Omega_2)$$
with equivalent norms. Each of the spaces in the intersection is a tensor product Hilbert space where SVD applies.
We investigate several approaches to construct low-rank approximations for a function
$u\in H^1(\Omega_1\times\Omega_2)$
.
A Blueprint for Teaching Excellence
Authors: Pickford Ruth 
Published: May 2018

This article outlines an innovative and highly practical model that holistically and synoptically integrates the factors that underpin strategic approaches to developing teaching excellence within a course, an institution or more widely.
It combines and articulates the various drivers towards excellence widely discussed currently, from the perspectives of students, institutions and those who teach them. Integral to the model are the elements of progression, satisfaction and graduate outcomes that align fully with current imperatives around teaching excellence.
Drawing upon extant elements of Higher Education pedagogy, this article adopts a Boyerian approach to scholarship integrating original research that has been applied in diverse contexts in an innovative way (Boyer, 1990), to provide a route-map or blueprint for the design and delivery of curriculum, teaching and learning environments. The model will be of use to individuals, course directors, learning and teaching directorates, institutional leaders working in higher education.
