The United Nations (UN) has fallen short in meeting commitments - which date back to 1970 - to achieve gender parity. Conversely, UNICEF globally has achieved gender parity. This global average however hides a gender imbalanced workforce at the regional level, in country offices and in functional areas. At UNICEF Nepal, men are over-represented in the workforce. The most significant gender imbalance lies within the category of national staff. Based on analysis of Human Resources (HR) recruitment and workforce data and interviews with UN staff, the research identified potential reasons for the under-representation of Nepalese women. Nepalese women are not leaving their jobs any more than men, career development opportunities are similar for men and women, selection procedures do not discriminate against women, there are policies in place for flexible work arrangements. From this elimination process, the main reason for the under-representation of women at UNICEF Nepal is that only a small number of women are applying to positions in the first place. From an array of potential reasons for women not applying to UNICEF Nepal, UNICEF can address the perception that UNICEF is a boys’ club that is inflexible in terms of working arrangements. Next, the research explored solutions from other UNICEF country offices, UN entities, the private sector and academia. The study presented practical solutions for UNICEF Nepal to adopt: Temporarily hiring only women, talent outreach, adapting and creating new traineeship and fellowship programmes, better communicating UNICEF’s goals on gender parity and job advertisements tailored to women. Beyond its direct application to UNICEF Nepal, this paper could inspire reflection at the country office, regional office and headquarters on solutions to achieve a more diverse workforce respecting gender balance, equitable geographical distribution, caste and others. In sum, it could guide reflection on solutions for UNICEF to have a workforce more representative of the society. [less ▲]

In the Euclidean case, it is well-known, by Malgrange and Ehrenpreis, that linear differential operators with constant coefficients are solvable. However, what happens, if we genuinely extend this situation and consider systems of linear invariant differential operators, is still solvable? In case of Rn (for some positive integer n), the question has been proved mainly by Hörmander. We will show that this remains still true for Riemannian symmetric spaces of non-compact type X = G/K. More precisely, we will present a possible strategy to solve this problem by using the Fourier trans- form and its Paley-Wiener(-Schwartz) theorem for (distributional) sections of vector bundles over X. We will get complete solvability for the hyperbolic plane H2 = SL(2, R)/SO(2) and beyond. This work was part of my doctoral dissertation supervised by Martin Olbrich. [less ▲]

Solvation free energies of neutral amino acids in water and in chloroform were computed from extensive molecular dynamics simulations using multiconfiguration thermodynamic integration. The values computed for the AMBER force field are in very good agreement with available experimental data (rms differences of 5.1 kJ mol(-1) for the solvation free energies and 6.4 kJ mol(-1) for the transfer free energies of amino acids between water and chloroform) and with existing calculations. We derived an additive residue-scale solvation model formulated as the sum of a nonpolar term that is proportional to the molecular surface area and an electrostatic term (Kirkwood-Onsager model) for the hydration free energy of a dipole in a solvated cavity. This model can surprisingly well describe the solvation free energies in water and chloroform as well as the transfer free energies of amino acids between the two solvents when suitably adapted cavity radii are used. Root-mean-square differences of the predicted values with respect to the values calculated from thermodynamic integration are 1.8, 5.9, and 7.7 kJ mol(-1), respectively. [less ▲]

We present a computer simulation study on the crystal nucleation process in suspensions of hard spheres, fully taking into account the solvent hydrodynamics. If the dynamics of crystallization in this system were purely diffusive, the crystal nucleation rate would be inversely proportional to the solvent viscosity. However, we observe that the nucleation rate is enhanced at high viscosities with respect to the diffusive behaviour. This effect might explain the large discrepancy between the nuclation rates obtained by simulation and experiment that have been reported in the literature so far. [less ▲]

Learning mathematics in a second language is a challenge for many learners. The purpose of the study was to provide new insights into the role of the language context in mathematic learning and more particularly arithmetic problem solving. We investigated this question in a GermaneFrench bilingual educational setting in Luxembourg. Participants with increasing bilingual proficiency levels were invited to solve additions in both their first and second instruction languages: German and French. Arithmetic problems were presented in two different conditions: preceded by a semantic judgment or without additional language context. In the French session we observed that additions were systematically performed faster in the condition with an additional language context. In contrast no effect of the context was observed in the German session. In conclusion, providing a language context enhanced arithmetic performances in bilinguals' second instruction language. This finding entails implications for designing optimal mathematic learning environments in multilingual educational settings. [less ▲]

We investigate the n-variable real functions G that are solutions of the Chisini functional equation F(x) = F(G(x),...,G(x)), where F is a given function of n real variables. We provide necessary and sufficient conditions on F for the existence and uniqueness of solutions. When F is nondecreasing in each variable, we show in a constructive way that if a solution exists then a nondecreasing and idempotent solution always exists. We also provide necessary and sufficient conditions on F for the existence of continuous solutions and we show how to construct such a solution. We finally discuss a few applications of these results. [less ▲]

Triple graph grammars (TGGs) provide a formal framework for bidirectional model transformations. As in practice, TGGs are primarily used in pure model-to-model transformation scenarios, tools for text-to-model and model-to-text transformations make them also applicable in text-to-text transformation contexts. This paper presents a solution for the text-to-text transformation case study of the Transformation Tool Contest 2014 on translating FIXML (an XML notation for financial transactions) to source code written in Java, C# or C++. The solution uses the HenshinTGG tool for specifying and executing model-to-model transformations based on the formal concept of TGGs as well as the Xtext tool for parsing XML content to yield its abstract syntax tree (text-to-model transformation) and serialising abstract syntax trees to source code (model-to-text transformation). The approach is evaluated concerning a given set of criteria. [less ▲]

The exact resolution of large instances of combinatorial optimization problems, such as three dimensional quadratic assignment problem (Q3AP), is a real challenge for grid computing. Indeed, it is necessary to reconsider the resolution algorithms and take into account the characteristics of such environments, especially large scale and dynamic availability of resources, and their multi-domain administration. In this paper, we revisit the design and implementation of the branch and bound algorithm for solving large combinatorial optimization problems such as Q3AP on the computational grids. Such gridification is based on new ways to effi- ciently deal with some crucial issues, mainly dynamic adaptive load balancing and fault tolerance. Our new approach allowed the exact resolution on a nation-wide grid of a dif- ficult Q3AP instance. To solve this instance, an average of 1,123 computing cores were used for less than 12 days with a peak of around 3,427 computing cores. [less ▲]
