This paper examines the current level of adoption of Supply Chain Management (SCM) practices in the electro-electronic sector in Brazil and aims to identify the management and Information Technology (IT) actions that have been implemented to support the adoption of those practices. An e-mail survey was conducted. Descriptive statistics techniques were employed for data analysis. This study makes contributions to the electro-electronics sector and to the topics related to SCM, such as identifi cation and level of adoption of SCM practices. Another contribution of this research is the investigation of whether approaches such as Enterprise Resources Planning (ERP), Workshop with Customers, Electronic Data Interchange (EDI), Workshop with Suppliers and electronic Kanban are commonly used to support SCM practices. So far, this is the fi rst research on SCM practices in the electro-electronics sector in Brazil. Copyright © 2012 Inderscience Enterprises Ltd.

Context is critical for recognizing environments and for searching for objects within them: contextual associations have been shown to modulate reaction time and object recognition accuracy, as well as influence the distribution of eye movements and patterns of brain activations. However, we have not yet systematically quantified the relationships between objects and their scene environments. Here I seek to fill this gap by providing descriptive statistics of object-scene relationships. A total of 48, 167 objects were hand-labeled in 3499 scenes using the LabelMe tool (Russell et al., 2008). From these data, I computed a variety of descriptive statistics at three different levels of analysis: the ensemble statistics that describe the density and spatial distribution of unnamed “things” in the scene; the bag of words level where scenes are described by the list of objects contained within them; and the structural level where the spatial distribution and relationships between the objects are measured. The utility of each level of description for scene categorization was assessed through the use of linear classifiers, and the plausibility of each level for modeling human scene categorization is discussed. Of the three levels, ensemble statistics were found to be the most informative (per feature)...

Papua New Guinea (PNG) has implemented numerous institutional changes over the past fifteen years with the avowed aim of bringing government closer to the people, improving accountability and, by extension, local infrastructure development and service delivery. To date however, there has been little empirical evidence to establish whether these changes have impacted the provision of local infrastructure. Similarly, there is little empirical evidence revealing the main political economy factors that influence the way that resources are actually planned, spent, and impact communities at the sub-national level. This report investigates the determinants of local infrastructure projects at the ward level, the lowest level of government in PNG, to assess the impact of these institutional changes and to identify the importance of other factors, in particular local collective action. It does this through a survey covering more than 1000 households across 49 yards in nine PNG districts. It also presents descriptive statistics on the basic characteristics of the households that were surveyed...

During the early 2000s, Moldova experienced strong economic growth and poverty and inequality reductions. This paper aims at uncovering the patterns behind these poverty trends by looking at economic mobility and its associated factors in Moldova. The findings build on the synthetic panel approach and allow for a non-anonymous view of the process of poverty reduction. The data used for this country study on Moldova come from the Household Budget Survey, which is conducted on a yearly basis. The paper presents transition matrices to look at the patterns of economic mobility across selected consumption thresholds, as well as descriptive statistics and a linear probability model aimed at identifying correlates of economic mobility. The findings show that the observed poverty reductions happened with little churning, and highlight the importance of education and employment on upward economic mobility in Moldova in the 2000s, as well as the role of public and private transfers.

The Latin America and Caribbean (LAC) region has seen a decade of remarkable growth and income convergence. Growth has been a key driver for reducing poverty and boosting shared prosperity. It has been debated how much of this decade of growth has been driven by policy reforms and how much was due to the favorable external conditions. While external factors were supportive and relevant, the effect of domestic policies was just as relevant for explaining LAC's recent growth performance. The emphasis of domestic policy has shifted from stabilization policies to structural policies. In addition, a benchmarking exercise reveals which policy gaps will lead to the highest potential growth-payoffs for each country and helps identify potential trade-offs. The authors analyze growth in LAC using descriptive statistics and growth econometrics. The authors use these results for explaining the pattern of growth in LAC over the last decade, for looking ahead, and to identify potential policy gaps.

These lecture notes were written with the aim to provide an accessible though technically solid introduction to the logic of systematical analyses of statistical data to undergraduate and to postgraduate students, in particular in the Social Sciences and in Economics. They may also serve as a general reference for the application of quantitative--empirical research methods. In an attempt to encourage the adoption of an interdisciplinary perspective on quantitative problems arising in practice, the notes cover the four broad topics (i) descriptive statistical processing of raw data, (ii) elementary probability theory, mainly as seen from a frequentist's viewpoint, (iii) the operationalisation of one-dimensional latent statistical variables according to Likert's widely used scaling approach, and (iv) the standard statistical tests of hypotheses concerning (a) distributional differences of variables between subgroups of a target population, and (b) statistical associations between two variables. The lecture notes are fully hyperlinked, thus providing a direct route to original scientific papers as well as to interesting biographical information. They also list many commands for activating statistical functions and data analysis routines in the software packages SPSS...

## Descriptive Statistics of the Genome: Phylogenetic Classification of Viruses

Hernandez, Troy; Yang, Jie

In recent years there have been many proposed methods for phylogenetic classification of viruses. Performing these classifications in a timely manner is of interest to researchers and public health authorities. While multiple sequence alignment (MSA) remains the tool of choice for practitioners, alignment-free methods have gained popularity due to their substantial increases in speed and decreases in computational resources. Pairwise sequence alignment (PASC) is a middle-ground between the preceding two. We present a new family of alignment-free vectorizations of the genome, the generalized vector (GV), that maintains the speed of existing alignment-free methods and incorporates some of the interpretability of sequence alignment. This new alignment-free vectorization uses the frequency of genomic words (k-mers), as is done in the composition vector, and incorporates descriptive statistics of those k-mers' positional information, as inspired by the natural vector. We analyze 5 different characterizations of genome similarity using $k$-nearest neighbor classification, and evaluate these on two collections of viruses totalling over 10,000 viruses. We show that our proposed method performs better than, or at least as well as, other methods at every level of the phylogenetic hierarchy.

## Growing Networks: Limit in-degree distribution for arbitrary out-degree one

We compute the stationary in-degree probability, $P_{in}(k)$, for a growing network model with directed edges and arbitrary out-degree probability. In particular, under preferential linking, we find that if the nodes have a light tail (finite variance) out-degree distribution, then the corresponding in-degree one behaves as $k^{-3}$. Moreover, for an out-degree distribution with a scale invariant tail, $P_{out}(k)\sim k^{-\alpha}$, the corresponding in-degree distribution has exactly the same asymptotic behavior only if $2<\alpha<3$ (infinite variance). Similar results are obtained when attractiveness is included. We also present some results on descriptive statistics measures %descriptive statistics such as the correlation between the number of in-going links, $D_{in}$, and outgoing links, $D_{out}$, and the conditional expectation of $D_{in}$ given $D_{out}$, and we calculate these measures for the WWW network. Finally, we present an application to the scientific publications network. The results presented here can explain the tail behavior of in/out-degree distribution observed in many real networks.; Comment: 12 pages, 6 figures, v2 adds a section on descriptive statistics, an analisis on www network, typos added
