Adolescents with mental health problems in school: towards better help-seeking and support
No full textYour mental health during adolescence can have important consequences for your school functioning since adolescents with mental health problems have a higher chance of school dropout. To prevent school dropout, it is important that adolescents with mental health problems seek help in time and get appropriate support, either within school or through psychosocial care. However, asking for help and accepting help is often a problem for adolescents. Thus, increasing our insight into help-seeking behaviour of adolescents is important, not only for their current mental health, but also for their mental health in adulthood. Therefore, we investigated the help-seeking behaviour of adolescents, and the use of support in school by adolescents and the factors that influence it. We also investigated the feasibility of the Supported Education method, a support method that aims to support adolescents with mental health problems to remain in school. Finally, we also looked at treatment outcomes of psychosocial care for adolescents and the influence of health literacy skills. In general, we can conclude that mental health prevention and support for adolescents is essential and that there are many opportunities to address this in the school environment. In addition, it is important to stimulate knowledge and skills of adolescents on mental health, for example to help them seek help and talk about mental health, as well as to create a mental health positive climate in schools. This needs a school wide approach, in which school management, education professionals and adolescents are involved

Called to mission : Mennonite women missionaries in Central Africa in the second half of the twentieth century
No full textIncludes bibliographical references (leaves 195-198).This thesis is an investigation of the "sense of call" as a potential support factor for Mennonite women missionaries from North America based in Central Africa during the latter half of the twentieth century. The investigation is conducted in two main parts. In the first we investigate the theological-historical distinctives of the Anabaptist/Mennonite tradition; in the second part, through a case study, we examine how a select number of women missionaries interpreted their call in relation to their heritage, how their sense of call functioned as a support factor or otherwise, and whether this was determined in any significant way by the Anabaptist/Mennonite tradition. Central to the study is a pastoral concern for women missionaries as women whose missionary role has placed special burdens on them in situations of cultural dislocation

An international growth strategy for a fast-growing last mile delivery planning company
No full textPlotwise is a tech scale-up that offers continuous planning for last mile delivery. By providing data-driven AI planning software as a service, the company strives to improve the delivery planning process of its customers and thereby allowing them to handle the growth in demand for home delivery. The home delivery market is expanding at an exponential rate. The COVID-19 pandemic has pushed the e-commerce market five years ahead, more packages are delivered every day and this volume is rapidly growing. Online shoppers are reshaping the delivery economy from supply- to demand-driven. They expect their deliveries to be free, fast and convenient. At the same time, logistics operators and (online) retailers strive to find the optimal balance between costs, operational efficiency and customer experience. Improving environmental performance is getting increasingly important as well. This puts significant stress on their planning and delivery process. Plotwise seems successful in terms of its product-market fit. Hence, the management team wants to rapidly scale the company through signing new customers in at least four additional European countries between now and 2022. For this reason, the Head of Sales of Plotwise asked the author of this thesis to design a sales strategy that guides the company in entering European countries with its current product. The author created this sales strategy through performing a literature review, an internal analysis, an external analysis and quantitative market research. Strategic design principles complemented these research methodologies. This thesis presents the results of this research. In the literature review, the author discusses theoretic elements of traditional market entry strategy literature. The review synthesises the findings into a model that guided the development of the sales strategy. An internal analysis on Plotwise’s vision, mission, product, business model and culture shows that the company is fit for international expansion. However, the analysis shows that the sales team faces several challenges that possibly slow down this scaling. To tackle the identified challenges, the author presents three sales tools in combination with a roadmap for 2021 and 2022. The expectation is that these tools will improve the lead conversion, thereby increasing the number of signed customers. The author created a market analysis framework to conduct a quantitative market study. The result of this analysis is a list of most attractive countries to enter; the advice is to enter the UK market first, followed by Sweden, Norway and France. This advice deviates from an initial assumption on entry sequence as made by the management team of Plotwise. Additionally, the author advises to focus on logistic service providers (LSP), third party logistics (3PL) companies, electronics e-tailers, brands and (online) grocery stores as first customer segments. Lastly, the author advises Plotwise to position as “future-proof planning partner for delivery service optimisation”. This positioning resonates with online shopper behaviour and differs from the competition. Moreover, it leverages the core competencies of Plotwise.Strategic Product Desig
Breadwinner or caregiver? - how household role affectslabor choices in Mexico
No full textRecent volatility in the Mexican economy, has required households to alter patterns of participation in the labor force, voluntarily or not. The author uses panel data to examine patterns of labor force entry among adult men, and women with different household responsibilities, asking whether gender is a primary determinant, shaping these patterns. She finds that labor supply patterns are driven more by household role, than by gender. Heads of households, regardless of sex, behave similarly. Women who have neither spouses, nor children behave more like men, than like married women. They are also more likely than any other group to have inflexible, higher-paying jobs in the formal sector - which raises the question: Do employers discriminate, based on gender, or on household structure? She also detects a strong added-worker effect among secondary workers, a result not detected in the labor markets of developed countries that have social insurance programs. Finally she finds that wives'choice of sector during downturns, is subject to the households'earning needs, that husbands use informal wage, or contract employment as an employer of last resort, only in response to negative income shocks to the household, and that single mothers do not select the informal sector over the formal sector in response to either expected, or realized negative income shocks. The policy implications? Interventions that target women aren't necessarily appropriate, because women are heterogeneous. And programs that aid household heads - male or female - should be directed toward employment that will last beyond the economic shock.Environmental Economics&Policies,Labor Markets,Educational Policy and Planning,Labor Policies,Health Economics&Finance,Environmental Economics&Policies,Health Economics&Finance,Labor Markets,Educational Policy and Planning,Health Monitoring&Evaluation
Defining “k <sub>f</sub>-factors” for threshold reactions
No full textThe k0-method (De Corte in The k0-standardization method: move to the optimization of neutron activation analysis. Habil. Thesis, Ghent University, Belgium, 1987) was developed solely for the use of (n, γ) nuclear reactions in neutron activation analysis. For this, a definition of only the thermal and epi-thermal flux was needed. The fast flux of the fission neutrons was not taken into account although it was considered for primary interferences by De Corte0. The energy distribution of the fission neutrons can be rather well described by a Watt distribution but is reactor dependent. To complicate things, the activation cross-section behaviour is nuclide dependent. In order to incorporate threshold reactions in the k0-method we propose to use predefined kf-factors, measuring the fast flux using a Ni-58 monitor, and to introduce an h-factor that accounts for all deviations for a specific reaction and irradiation facility. It is shown, based on data from Verheijke, that there are useful correlations for Ni-58, Ti-47 and Ti-48. Activation cross section functions indicate that there are possible more relations that might allow h-factors to be predicted.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public
Sectoral allocation by gender of Latin American workers over the liberalization period of the 1990s
No full textThe recent restructuring of Latin American economies has renewed interest in the effects of trade liberalization, on labor markets, and on the gender division of labor. The author does not attempt to establish casuality between economic reforms, and the types of jobs that men and women hold. Instead, she provides a detailed description of the trends in male, and female formal, and informal sector participation during the economic reform period in Argentina, Brazil, and Costa Rica. The author first compares the gender composition of the formal, informal wage, and self-employment sectors in a year before reforms (1988 for Argentina, 1989 for Brazil, and Costa Rica), and a year after reforms implementation (1997 for Argentina, 1995 for Brazil and Costa Rica). Although women continued to be more likely than men to work in the informal wage sector, there is no trend of"masculinization"or"feminization"of the informal sector, or any other. Instead, in Argentina men have overtaken women as the most prevalent workers in the informal wage sector, while in Brazil, the opposite has occurred (as men move into self-employment). In Costa Rica there have been no statistical, observable changes. The author then considers the distribution across sectors within each gender group, to identify whether men, and women are more likely to select different sectors in the post-reform period relative to the pre-reform period. Among both men, and women in all three countries (except Brazilian men), workers have become more likely to hold informal wage jobs, and less likely to hold formal sector jobs. Trends in human capital accumulation explain these changes for both men, and women, while changes in gender roles, primarily in homecare and marriage, do not seem to have an effect.Health Monitoring&Evaluation,Labor Policies,Population&Development,Public Health Promotion,Environmental Economics&Policies,Health Monitoring&Evaluation,Environmental Economics&Policies,Population&Development,Banks&Banking Reform,Work&Working Conditions
Detection limits should be a thing of the past in gamma-ray spectrometry in general as well as in neutron activation analysis
No full textIn gamma-ray spectrometry with high-resolution detectors, full-energy peaks are often to be detected by a peak-search algorithm, with a threshold for detection. Detection limits can be derived from this. Detection limits are often computed along with measured activities or concentrations. When an analyte is not detected, the detection limit remains as the only available information. This leads to inhomogeneous datasets that are difficult or impossible to process correctly without introducing artefacts or biases. Here, it is proposed to determine peak areas at predetermined energies. An unbiased result with its uncertainty always results, obviating the “detection limit” concept.RID/Kernenergiewet Organisati
Charge Scheduling of Electric Vehicles for Last-Mile Distribution of an E-grocer
No full textThis paper proposes a model for charge scheduling of electric vehicles in last-mile distribution that takes into account battery degradation. A mixed integer linear programming formulation is proposed that minimizes labor, battery degradation and time-dependent energy costs. The benefit of implementing charge schedule optimization is assessed for a real-life case study at e-grocer Picnic. It is shown that charging optimization yields an overall reduction of charging costs by 25.2% when compared to the current operational charging performance. Furthermore, the impacts of three different shift schedule types, the increase in vehicle battery size and the coordinated charging are investigated. It turns out that more energy demanding shift schedules result in higher average charging cost per charged amount of energy. The introduction of a larger battery size as well as coordinated charging show potential for decreasing overall costs.
