Authors: Neves Leticia Nunes das
Published: February 2018

Em 1985-89 a reforma agrária ganhou força na região do bico do papagaio, causando grandes conflitos entre os proprietários de terra e os componentes do movimento MST, esse período ficou conhecido em virtude da quantidade de pessoas que foram mortas e feridas, para que fosse conseguido êxito naquilo que estava sendo reivindicado. Atualmente os movimentos da reforma agrária no estado do Tocantins são menos violentos, se tornaram mais organizados e articulados, permitindo assim que os objetivos idealizados por este grupo sejam alcançados sem que ocorra tanta violência. O artigo trata-se dos resultados de uma pesquisa realizada com base em revisão bibliográfica, e uma visita a campo, em um acampamento de integrantes do movimento MST (Movimento dos Trabalhadores Rurais Sem Terra), que estava localizado as margens da rodovia que dá acesso à cidade de macaúba do Tocantins. O principal objetivo é constatar e apresentar à similaridade e as diferenças entre o movimento que estão ocorrendo atualmente com o que ocorreu nos anos 80 e o que está ocorrendo atualmente. As similaridades encontradas foram a ajuda mutua, o envolvimento dos lideres com a religião, as regras do acampamento em relação a proibição de violência e uso de drogas, a principal diferença encontrada foi o so dos meios tecnológicos para escolher a área onde o acampamento deveria ser montado.

AVALIAÇÃO DA PRECISÃO EXPERIMENTAL DE UM EXPERIMENTO DE MILHO EM CONSÓRCIO COM FEIJÃO PARA A PRODUÇÃO DE MILHO VERDE E SECO
Authors: Santos Patricia da Silva
Published: February 2018

O milho é uma das culturas agrícolas de maior importância econômica e social, pois é cultivada por pequenos e grandes produtores. Os pequenos produtores em sua maioria utilizam o sistema de consórcio em sua produção, por isso, diversos experimentos dessa natureza têm sido realizados. Esse tipo de experimento, devido sua natureza heterogênea apresenta sempre coeficiente de variação elevado. Para verificar a precisão experimental, muitos pesquisadores estão utilizando outros parâmetros estatísticos, como o teste F, Tukey, acurácia, entre outros. Esse trabalho teve como objetivo avaliar a precisão experimental de um experimento de milho em consórcio com feijão para a produção de milho verde e seco. Foram utilizados nesse experimento quatro genótipos de milho nos sistemas de cultivo consorciado e em monocultivo. Pode-se observar que a utilização da acurácia seletiva é a melhor alternativa para avaliar a precisão experimental em experimentos em consórcio. O experimento em estudo apresentou acurácia entre 0,91 e 0,95, respectivamente para massa de espigas comerciais com palha e rendimento de grãos, apresentando assim uma boa precisão experimental.

Federal Statistical Confidentiality and Business Data: Twentieth Century Challenges and Continuing Issues
Authors: Anderson Margo J. , Seltzer William
Published: February 2018

The roots of the modern concept of statistical confidentiality in the US federal statistical system can be traced directly back to the late nineteenth century efforts of statisticians to ensure full and accurate responses by businesses to statistical inquiries. Officials argued that such confidentiality guarantees were needed to ensure that the providers of enterprise and establishment data could be confident that the statistical agencies could not be forced to share their responses with others, such as regulatory or tax authorities, congressional investigators, prying journalists, and competitors, who might use this information to the detriment of the data provider. Nevertheless, over the years, the principle of statistical confidentiality with respect to information provided by businesses in statistical inquiries has been repeatedly challenged by other executive branch departments, independent regulatory agencies, the courts, Congress, and members of the public, with quite varied results.
The paper uses the published record and archival research to examine the history of challenges to statistical confidentiality, and the responses of the statistical agencies, the federal statistical system as a whole, including the office of the chief statistician in OMB (and its predecessors), executive department and independent non-statistical agencies, the courts, and Congress as well as representatives of the business community. Long-term trends and the implications for maintaining and strengthening the confidentiality protections for establishment- and enterprise-level business data provided to federal agencies for statistical purposes are discussed.
Data Confidentiality: The Next Five Years Summary and Guide to Papers

Published: February 2018

On May 1–2, 2008, the National Center for Health Statistics/CDC (NCHS) and the National Institute of Statistical Sciences (NISS) co-sponsored a workshop “Data Confi- dentiality: The Next Five Years,” which was held at NCHS’ headquarters in Hyattsville, MD. The purpose of the workshop was to bring together the academic and federal data confidentiality research communities, including mathematicians, mathematical statisticians, statisticians, computer scientists, cryptographers, and federal agency “owners” of data confidentiality problems in order to:

Identify important unsolved research problems associated with data confidentiality;
Articulate a research agenda that both addresses those problems and responds to current and emerging needs among federal statistical agencies;
Discuss and catalyze the kinds of collaborations among mathematicians, mathematical statisticians, statisticians, computer scientists, cryptographers, domain scientists, and data-owning agencies that are needed to pursue the research agenda.
Model Selection when multiple imputation is used to protect confidentiality in public use data
Authors: Kinney Satkartar K. , Reiter Jerome P. , Berger James O.
Published: February 2018

Several statistical agencies use, or are considering the use of, multiple imputation to limit the risk of disclosing respondents' identities or sensitive attributes in public use files. For example, agencies can release partially synthetic datasets, comprising the units originally surveyed with some values, such as sensitive values at high risk of disclosure, or values of key identifiers, replaced with multiple imputations. We describe how secondary analysts of such multiply-imputed datasets can implement Bayesian model selection procedures that appropriately condition on the multiple datasets and the information released by the agency about the imputation models. We illustrate by deriving Bayes factor approximations and a data augmentation step for stochastic search variable selection algorithms.

Is the Privacy of Network Data an Oxymoron?
Authors: Fienberg Stephen E.
Published: February 2018

While social networks are now a part of everyday life for the vast majority of people using computers, smartphones, and tablets, privacy is but an afterthought. Google+ has in excess of 100 million users a month while Facebook has topped 1 billion. Other more specialized networks such as Linked-in add to the fray. But from a privacy perspective the biggest concern for users should be the efforts to integrate the networking apps into all other forms of online activity as well as the constant effort to link additional data to network information, in addition to the network owners’ efforts to market that information to third party vendors. Further, Facebook and other networking sites have already begun to build search capabilities and other facilities into their systems that extend the information they collect from users even further. What protections do users really have?
Random Differential Privacy
Authors: Hall Robert , Wasserman Larry , Rinaldo Alessandro
Published: February 2018

We propose a relaxed privacy definition called {\em random differential privacy} (RDP). Differential privacy requires that adding any new observation to a database will have small effect on the output of the data-release procedure. Random differential privacy requires that adding a {\em randomly drawn new observation} to a database will have small effect on the output. We show an analog of the composition property of differentially private procedures which applies to our new definition. We show how to release an RDP histogram and we show that RDP histograms are much more accurate than histograms obtained using ordinary differential privacy. We finally show an analog of the global sensitivity framework for the release of functions under our privacy definition.
Privacy via the Johnson-Lindenstrauss Transform
Authors: Kenthapadi Krishnaram , Korolova Aleksandra , Mironov Ilya , Mishra Nina
Published: February 2018

Suppose that party A collects private information about its users, where each user's data is represented as a bit vector. Suppose that party B has a proprietary data mining algorithm that requires estimating the distance between users, such as clustering or nearest neighbors. We ask if it is possible for party A to publish some information about each user so that B can estimate the distance between users without being able to infer any private bit of a user. Our method involves projecting each user's representation into a random, lower-dimensional space via a sparse Johnson-Lindenstrauss transform and then adding Gaussian noise to each entry of the lower-dimensional representation. We show that the method preserves differential privacy---where the more privacy is desired, the larger the variance of the Gaussian noise. Further, we show how to approximate the true distances between users via only the lower-dimensional, perturbed data. Finally, we consider other perturbation methods such as randomized response and draw comparisons to sketch-based methods. While the goal of releasing user-specific data to third parties is more broad than preserving distances, this work shows that distance computations with privacy is an achievable goal.
On Regression-Tree-Based Synthetic Data Methods for Business Data
Authors: Lee Joo Ho , Kim In Yong , O'Keefe Christine M.
Published: February 2018

This paper concerns the use of synthetic data for protecting the confidentiality of business data during statistical analysis. Synthetic data sets are traditionally constructed by replacing sensitive values in a confidential data set with draws from statistical models estimated on the confidential data set. Unfortunately, the process of generating effective statistical models can be a difficult and labour-intensive task. Recently, it has been proposed to use easily-implemented methods from machine learning instead of statistical model estimation in the data synthesis task. J. Drechsler and J.P. Reiter (2011) have conducted an evaluation of four such methods, and have found that regression trees could give rise to synthetic data sets which provide reliable analysis results as well as low disclosure risks. Their conclusion was based on simulations using a subset of the 2002 Uganda census public use file. It is an interesting question whether the same conclusion applies to other types of data with different characteristics, for example business data which have quite different characteristics from population census and survey data. In particular, business data generally have few variables that are mostly categorical, and often have highly skewed distributions with outliers.

In this paper we investigate the applicability of regression-tree-based methods for constructing synthetic business data. We give a detailed example comparing exploratory data analysis and linear regression results under two variants of a regression-tree-based synthetic data approach. We also include an evaluation of the analysis results with respect to the results of analysis of the original data. We further investigate the impact of different stopping criteria on performance.

While it is certainly true that any method designed to protect confidentiality introduces error, and may indeed give misleading conclusions, our analysis of the results for synthesisers based on CART models has provided some evidence that this error is not random but is due to the particular characteristics of business data. We conclude that more careful analysis needs to be done in applying these methods and end users certainly need aware of possible discrepancies.
Privacy-Preserving Data Sharing for Genome-Wide Association Studies
Authors: Uhler Caroline , Slavkovic Aleksandra B. , Fienberg Stephen E.
Published: February 2018

Traditional statistical methods for confidentiality protection of statistical databases do not scale well to deal with GWAS databases especially in terms of guarantees regarding protection from linkage to external information. The more recent concept of differential privacy, introduced by the cryptographic community, is an approach which provides a rigorous definition of privacy with meaningful privacy guarantees in the presence of arbitrary external information, although the guarantees may come at a serious price in terms of data utility. Building on such notions, we propose new methods to release aggregate GWAS data without compromising an individual’s privacy. We present methods for releasing differentially private minor allele frequencies, chi-square statistics and p-values. We compare these approaches on simulated data and on a GWAS study of canine hair length involving 685 dogs. We also propose a privacy-preserving method for finding genome-wide associations based on a differentially-private approach to penalized logistic regression.
Improving User Choice Through Better Mobile Apps Transparency and Permissions Analysis
Authors: Liccardi Ilaria , Pato Joseph , Weitzner Daniel J.
Published: February 2018

Our personal information, habits, likes and dislikes can be all deduced from our mobile devices. Safeguarding mobile privacy is therefore of great concern. Transparency and individual control are bedrock principles of privacy but making informed choices about which mobile apps to use has been shown to be difficult. In order to understand the dynamics of information collection in mobile apps and to demonstrate the value of transparent access to the details of mobile applications information access permissions, we have gathered information about 528,433 apps on Google Play, and analyzed the permissions requested by each app. We develop a quantitative measure of the risk posed by apps by devising a ‘sensitivity score’ to represent the number of occurrences of permissions that read personal information about users where network communication is possible. We found that 54% of apps do not access any personal data. The remaining 46% collect between 1 to 20 sensitive permissions and have the ability to transmit it outside the phone. The sensitivity of apps differs greatly between free and paid apps as well as between categories and content rating. Sensitive permissions are often mixed with a large amount of low-risk permissions and hence are difficult to identify. Easily available sensitivity scores could help users making more informed decision about choosing an app that could pose less risk in collecting personal information. Even though an app is “self-described” to be suitable for a certain subset of users (i.e children) it might contain content ratings and permission requests that are not appropriate or expected. Our experience in doing this research shows that it is difficult to obtain information about how personal data collected from apps is used or analyzed. In fact only 0.37% (1,991) of the collected apps show to have declared a “privacy policy”. Therefore, in order to make real control available to mobile users, apps distribution platforms should provide more detailed information about how their data if accessed is used. To achieve greater transparency and individual control, apps distribution platforms which do not currently make raw permission description accessible for analysis could change their design and operating policies to make this data available prior to installation.
Towards a Systematic Analysis of Privacy Definitions
Authors: Lin Bing-Rong , Kifer Dan
Published: February 2018

In statistical privacy, a privacy definition is regarded as a set of algorithms that are allowed to process sensitive data. It is often helpful to consider the complementary view that privacy definitions are also contracts that guide the behavior of algorithms that take in sensitive data and produce sanitized data. Historically, data privacy breaches have been the result of fundamental misunderstandings about what a particular privacy definition guarantees.
Privacy definitions are often analyzed using a highly targeted approach: a specific attack strategy is evaluated to determine if a specific type of information can be inferred. If the attack works, one can conclude that the privacy definition is too weak. If it doesn't work, one often gains little information about its security (perhaps a slightly different attack would have worked?). Furthermore, these strategies will not identify cases where a privacy definition protects unnecessary pieces of information.
On the other hand, technical results concerning generalizable and systematic analyses of privacy are few in number, but such results have significantly advanced our understanding of the design of privacy definitions. We add to this literature with a novel methodology for analyzing the Bayesian properties of a privacy definition. Its goal is to identify precisely the type of information being protected, hence making it easier to identify (and later remove) unnecessary data protections.
Using privacy building blocks (which we refer to as axioms), we turn questions about semantics into mathematical problems -- the construction of a consistent normal form and the subsequent construction of the row cone (which is a geometric object that encapsulates Bayesian guarantees provided by a privacy definition).
We apply these ideas to study randomized response, FRAPP/PRAM, and several algorithms that add integer-valued noise to their inputs; we show that their privacy properties can be stated in terms of the protection of various notions of parity of a dataset. Randomized response, in particular, provides unnecessarily strong protections for parity, and so we also show how our methodology can be used to relax privacy definitions.

The accuracy of type, number, price, place, time and quality are the expectations that every farmer expects in the process of distributing and procurementing subsidized fertilizer. But the various alternatives which have already given or designed were not be able to solve the scarcity of fertilizer and it was happening very frequent in our  environment. The usage of control card (farmer card) has been designed by goverment in 2007-2008 but it was not well distributed to all regions in East Nusa Tenggara. Whereas the usage of this card can be a good solution that can help in controling (managing) the fertilizer distribution so the fertilizer can be given to the appropriate farmers. The implementing of farmer card along with the making of information system of fertilzer distribution in Gerung is designed tosolve the inaccuracies of subsidized feltilizer distribution.

Dalam pemrograman android banyak sekali cara yang dapat digunakan untuk mencapai sebuah luaran. Salah satunya adalah membuat list. Dalam membuat list banyak metode yang bisa digunakan, antara lain membuat model, atau membuat adapter sendiri. Dalam tulisan yang saya buat kali ini akan dibahas pembuatan list dengan menggunakan hashmap. Hashmap adalah sebuah bentuk abstrak dari sebuah key dan value, dari key dan value yang disediakan dapat dicocokkan dalam sebuah list.Metode yang akan dibandingkan adalah dengan menggunakan model. Hasil yang didapatkan adalah sebuah list yang sama, namun dengan penggunaan kode yang lebih minimalis dan lebih ringan dalam penggunaan memori. Penggunaan Hashmap lebih fleksibel, karena tidak perlu membuat model dan kelas baru,ataupun adapter baru.

Analysis of wear properties of Zn-based composites using the Taguchi method
Authors: Miloradović Nenad , Stojanović Blaža , Nikolić Ružica R. , Gubeljak Nenad
Published: February 2018

The tribological behavior of composites based on zinc aluminum ZA27 alloy, reinforced with silicon carbide (SiC) and graphite (Gr) particles is analyzed using the Taguchi method and described in this paper. Two sample composites were tested: the first containing 10 % of SiC and the second containing 10 % of SiC and 3 % Gr particles. They were prepared by the compo-casting procedure. The experiments were carried out using a block-on-disc tribometer under dry sliding test conditions. The tests were conducted with sliding speeds of 0.25, 0.5 and 1.0 m×s−1, normal loads of 10, 20 and 30 N and a sliding distance of 300 m. The wear surface of the composite material was examined using scanning electronic microscopy (SEM) and energy dispersive spectrometry (EDS). The influence of various parameters on the wear behavior was investigated by means and analysis of variance (ANOVA).
Progress in glacial geology during the last fifty years
Authors: Boulton G.S.
Published: February 2018

The principal objectives of glacial geology over the last 50 years have been to establish and explain the history of ice, and in particular glaciation, on Earth and to understand the origin of the erosional and depositional products of ice. One of its major successes has been to establish the tempo and magnitude of change in the global glacier mass during the late Cenozoic ice age, and to demonstrate Earth orbital forcing of these changes. On the larger time-scale of the whole geological record, there has been steady elucidation of the frequency of ice ages since the first evidence of glaciation in rocks 2700 Ma old.

There has also been considerable progress in identifying the processes of glacial erosion and deposition and systematizing their products. It is now important that glacial geologists and glaciologists attempt to establish ways in which glacier behaviour is related to sedimentary processes, and via the geological product of those processes to relate the dynamics of glaciers in the past to processes in the lithosphere, hydrosphere, and atmosphere.
