occ2vec: A principal approach to representing occupations using natural language processing

We propose \textbf{occ2vec}, a principal approach to representing occupations, which can be used in matching, predictive and causal modeling, and other economic areas. In particular, we use it to score occupations on any definable characteristic of interest, say the degree of \textquote{greenness}. Using more than 17,000 occupation-specific text descriptors, we transform each occupation into a high-dimensional vector using natural language processing. Similar, we assign a vector to the target characteristic and estimate the occupational degree of this characteristic as the cosine similarity between the vectors. The main advantages of this approach are its universal applicability and verifiability contrary to existing ad-hoc approaches. We extensively validate our approach on several exercises and then use it to estimate the occupational degree of charisma and emotional intelligence (EQ). We find that occupations that score high on these tend to have higher educational requirements. Turning to wages, highly charismatic occupations are either found in the lower or upper tail in the wage distribution. This is not found for EQ, where higher levels of EQ are generally correlated with higher wages

Shank's transformation revisited

AbstractA unified and self-contained approach to the block structure of Shank's table and its cross rules is presented. Wynn's regular and Cordellier's singular cross rules are derived by the Schur-complement method in a unified manner without appealing to Padé approximation. Moreover, by extending the definition of Shank's transformation to certain biinfinite sequences and by introducing a parameter it is possible to get more consistency with respect to Möbius transformations. It is well known that Padé approximants in general don't have this property

Plantar, pescar... cozinhar e comer: estudando o sabor local

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Agroecossistemas.O alimento é tratado neste estudo como um condutor para se entender o ser humano em seu ambiente e nas suas relações sociais. Tais relações articulam-se quando se compreende o alimento a partir de sistemas alimentares e das culturas humanas, ou seja, quando se percebe que sociais. Este trabalho aborda tais relações a partir de um grupo social específico - os moradores antigos do bairro Campeche (Florianópolis, SC # Brasil), cognominados "nativos", com os quais se buscou compreender as relações entre as formas de obter os alimentos e a sua representação/significação dentro do cotidiano alimentar. Realizou-se uma pesquisa qualitativa, cujos dados principais se obteve por meio de entrevistas semi-estruturadas e do levantamento de documentos sobre a história da comunidade e do município. Os resultados mostraram que, até meados do século XX, as famílias de nativos ainda tinham como prática alimentar a variedade oferecida pelos alimentos locais - mandioca, feijão, batata-doce, amendoim, melancia, peixes e aves -, os quais representavam os períodos de plantio, colheita e extração (caso do peixe e dos frutos do mar), assim como lançavam mão das estratégias de circulação de alimentos (escambo ou venda) para complementação da dieta alimentar. Na tomada de decisão sobre o que, como e onde plantar, agiam diversos fatores pautados no conhecimento sobre os agroecossistemas e as necessidades de consumo alimentar das famílias, os quais se articulavam e garantiam a identidade do grupo. A partir de 1970, verificou-se que tanto as formas de obtenção como as práticas alimentares sofreram transformações decorrentes, sobretudo, do processo de avanço da urbanização na região. Como conseqüência, houve a redução de espaços agricultáveis, e os alimentos passaram então a ser ofertados por uma nova e crescente rede de mercados, muitas vezes não condizentes com aquela antiga produção local. O resultado final pôde ser constatado nas alterações em torno do ato alimentar, na incorporação de novos alimentos e preparações, bem como nas mudanças na comensalidade entre as gerações. O estudo indica para a importância de trabalhos, políticas públicas e ações efetivas direcionadas à valorização dos alimentos, das comidas e das antigas práticas construídas culturalmente por este grupo dentro de um novo contexto onde predomina um modo de vida urbano

A longitudinal study of kinematic stride characteristics in maximal sprint running

Purpose of the present study was to measure the kinematic stride characteristics of track-and-field-sprinters and jumpers in maximal sprint-running during different training periods (TP) of a double-periodisation (DP). 26 participants (7 females, age: 22.7 ± 5.7yrs, body mass: 60.1 ± 6.7kg, body height: 172.1 ± 4.4cm; 19 males, age: 20.9 ± 3.3yrs, body mass: 73.7 ± 6.5kg, body height: 182.3 ± 7.5cm) participated in flying 30-meter-sprints. Kinematic stride parameters (stride-velocity, stride-length, stride-frequency, contact-time, flight-time and stride-rhythm) were measured for every single stride with Optojump (Microgate S.r.L., Italy). The training data were collected via protocol. A variance analysis with repeated measures was calculated for 3 respectively 6 TPs as well as multiple regression functions for the stride-velocity. The longitudinal results showed significant values for the 6 TPs, however cyclic increase of maximal sprint-velocity (on average 0.42 ± 0.08m/s) with a DP that corresponded with the recorded training data. 3 TPs differed significantly in average stride-velocity, stride-length, stride-frequency and contact-time of the maximal sprint, but not in flight-time and stride-rhythm. Our findings suggest that kinematic stride characteristics depend on TP. A systematic training control to increase the sprint-speed must take into account these changes of the kinematic parameter during the training year

Representation of the Lagrange reconstructing polynomial by combination of substencils

The Lagrange reconstructing polynomial [Shu C.W.: {\em SIAM Rev.} {\bf 51} (2009) 82--126] of a function $f(x)$ on a given set of equidistant (\Delta x=\const) points $\bigl\{x_i+\ell\Delta x;\;\ell\in\{-M_-,...,+M_+\}\bigr\}$ is defined [Gerolymos G.A.: {\em J. Approx. Theory} {\bf 163} (2011) 267--305] as the polynomial whose sliding (with $x$) averages on $[x-\tfrac{1}{2}\Delta x,x+\tfrac{1}{2}\Delta x]$ are equal to the Lagrange interpolating polynomial of $f(x)$ on the same stencil. We first study the fundamental functions of Lagrange reconstruction, show that these polynomials have only real and distinct roots, which are never located at the cell-interfaces (half-points) $x_i+n\tfrac{1}{2}\Delta x$ ($n\in\mathbb{Z}$), and obtain several identities. Using these identities, by analogy to the recursive Neville-Aitken-like algorithm applied to the Lagrange interpolating polynomial, we show that there exists a unique representation of the Lagrange reconstructing polynomial on $\{i-M_-,...,i+M_+\}$ as a combination of the Lagrange reconstructing polynomials on the $K_\mathrm{s}+1\leq M:=M_-+M_+>1$ substencils $\{i-M_-+k_\mathrm{s},...,i+M_+-K_\mathrm{s}+k_\mathrm{s}\}$ ($k_\mathrm{s}\in\{0,...,K_\mathrm{s}\}$), with weights $\sigma_{R_1,M_-,M_+,K_\mathrm{s},k_\mathrm{s}}(\xi)$ which are rational functions of $\xi$ ($x=x_i+\xi\Delta x$) [Liu Y.Y., Shu C.W., Zhang M.P.: {\em Acta Math. Appl. Sinica} {\bf 25} (2009) 503--538], and give an analytical recursive expression of the weight-functions. We then use the analytical expression of the weight-functions $\sigma_{R_1,M_-,M_+,K_\mathrm{s},k_\mathrm{s}}(\xi)$ to obtain a formal proof of convexity (positivity of the weight-functions) in the neighborhood of $\xi=\tfrac{1}{2}$, under the condition that all of the substencils contain either point $i$ or point $i+1$ (or both).Comment: final corrected version; in print J.
