This essay examines Suzanne Collins’s monstrous “mutts” in her phenomenally popular series The Hunger Games. Hiltz is especially interested in Collins’s characterization of human-animal hybrids, investigating the relationship between the political commentary at work in the novels and these “monsters,” from the half-wolf, half-humans that nearly overtake Katniss at the Cornucopia in the first novel to the lizard-humans whispering her name throughout the viaducts beneath the city in the last. Hiltz focuses on the mutts as abject creatures, demonstrating the ways in which these uncanny monsters, quite literally making the familiar strange, are at once metaphors for the political control exerted by the Capitol, the rebels’ resistance to the Capitol’s power, and the disruption of natural order. She also concentrates on Katniss and Peeta muttations, each of them reformed by warring entities in service of “the greater good.” Most importantly, Hiltz emphasizes that Collins’s mutts are designed to demonstrate the fine and wavering line between good and evil, calling into question the nature of monstrosity, especially as it relates to human behavior. Her location of monstrosity in the protagonists themselves especially offers a new way of thinking about teen dystopic novels that engage horror as a means of conveying identities assaulted by external forces.

A identificação e mapeamento dos solos servem como subsidio para planejamentos agrícolas, levantamentos do uso da terra, estudos de terras para irrigação, estudos de preservação, análise e recuperação ambientais, predição de desastres naturais como o monitoramento de processos erosivos, dentre outros. Nesse sentido, os levantamentos e avaliações de solo, para fins agrícolas ou não, ganham importância, pois através deles é possível conhecer as propriedades desse recurso natural, permitindo sua utilização de forma consciente e adequada. O uso de sistemas de informações geográficas tem introduzido novos métodos para o levantamento e mapeamento de solos, por meio de modelagens, a partir da utilização de mapas temáticos básicos e modelos numéricos de terreno ou modelos digitais de elevação, que possibilitam, principalmente, a compreensão das relações entre a paisagem e as classes de solo. Assim, o objetivo deste trabalho foi a realização do levantamento e mapeamento dos solos do município de Inconfidentes - MG, utilizando técnicas de geoprocessamento, e a classificação pedológica até o quarto nível categórico através da generalização, a partir da descrição morfológica e determinações analíticas de perfis de solos representativos. Foi realizada a caracterização da área de estudos, a aquisição e tratamento de dados cartográficos. A descrição morfológica dos perfis foi realizada em pontos previamente definidos, representativos das distintas classes de solo do município. As análises físico-químicas foram realizadas em todas as amostras dos horizontes dos perfis de solos coletados em campo. A generalização do levantamento de solos foi elaborada através do processamento dos dados cartográficos e obtidos em campo, com a utilização do software ArGIS 9.3. O mapeamento pedológico do município foi então o resultado da integração e correlação dos dados altimétricos, da declividade, da rede de drenagem, do canal fluvial, do relevo e da litologia, associados com a caracterização feita em campo e as determinações analíticas. Como resultado, foi possível mapear as áreas de ocorrência de Latossolos, Gleissolos e Cambissolos, as três ordens de solos mais representativos do município, classificando-os até o quarto nível categórico. O uso das ferramentas de geotecnologia se mostrou muito útil para a caracterização das classes pedológicas e posterior generalização, uma vez que através delas foi possível inferir as condições ambientais de formação dos solos e integrá-los com dados de campo e análises laboratoriais.  ABSTRACT The identification and mapping of soils serve as subsidy for agricultural planning, land use surveys, land studies for irrigation, preservation studies, environmental analysis and recovery, prediction of natural disasters such as monitoring erosion, among others. In this sense, soil surveys and assessments, for agricultural purposes or not, become important because through them you can know the properties of this natural resource, allowing its use consciously and appropriately. The use of geographic information systems has introduced new methods to survey and soil mapping, through modeling, from the use of basic thematic maps and numerical terrain models and digital elevation models, which enable, especially, understanding the relationship between the landscape and the soil classes. The objective of this work was the completion of the survey and mapping of soils of city of Inconfidentes - MG, using geoprocessing techniques, and the pedological classification until the fourth categorical level by generalising from the morphological description and analytical profiles determinations representative soil. It was carried out to characterize their field of study, the acquisition and processing of cartographic data. The morphological description of the profiles was held in fixed locations, representative of the different soil classes of the municipality. The physicochemical analyzes were performed on all samples from the horizons of soil profiles collected in the field. Widespread soil survey was prepared by processing the cartographic data obtained in the field and, with the use of ArGIS 9.3 software. The pedological mapping of the municipality was then the result of the integration and correlation of altimetry data, the slope, the drainage network, the river channel, relief and lithology associated with the characterization made in the field and the analytical determinations. As a result, it was possible to map the areas of occurrence of Ferrasols, Cambisols and Gleysols, the three most representative soils of the municipality orders, sorting them until the fourth categorical level. The use of geotechnology tools proved very useful for the characterization of soil classes and subsequent generalization, since through them it was possible to infer the environmental conditions of soil formation and integrate them with field data and laboratory analysis. Keywords: Cambisols, Gleysols, Ferrasols, classification, hillslope.

The urban area consists of systems and sub-systems that have relationships with each other like a network. The development and changes in urban space are believed to influence the relationship between systems and also the meaning of all elements forming the urban spatial area. This also happens to the primary elements which are signs for the urban area. Given the changes in the city area, the existence of the primary elements as signs of a city area needs to be explored. The study is carried out on the primary elements in the city area which has a relatively complete city function. The case study is the European region in the center of Medan city, the capital of North Sumatra Province, Indonesia. This is a descriptive-analytical and interpretative-qualitative research. It aims to reveal all relationships that are intertwined in the function, form and meaning of the primary elements. The results of the study concluded that changes in primary elements as signs of the region shifted from symbolic meaning to pragmatic meaning.

The spatial organization and the topological organization of cities have a great influence on the lives of their inhabitants, including mobility efficiency. Entropy has been often adopted for the characterization of diverse natural and human-made systems and structures. In this work, we apply the exponential of entropy (evenness) to characterize the uniformity of city blocks. It is suggested that this measurement is related to several properties of real cities, such as mobility. We consider several real-world cities, from which the logarithm of the average shortest path length is also calculated and compared with the evenness of the city blocks. Several interesting results have been found, as discussed in the article.

ABSTRAK Waduk Jatibarang merupakan salah satu waduk yang memiliki peran penting di Kota Semarang sehingga kualitas perairannya perlu diperhatikan. Keberadaan fitoplankton di perairan berkaitan erat dengan kesuburan dan kualitas suatu perairan dikarenakan fitoplankton berperan sebagai produsen primer. Tujuan penelitian ini untuk mengetahui kualitas perairan berdasarkan kelimpahan fitoplankton serta melihat sejauh mana korelasi nitrat dan fosfat akan mempengaruhi kelimpahan fitoplankton diperairan. Penelitian dilakukan pada tanggal 27 Maret 2019 di Waduk Jatibarang semarang. Pengambilan sampel dilakukan menggunakan metode purposive sampling di tujuh stasiun dengan tiga titik kedalaman (permukaan, tengah dan dasar perairan) dan tiga pengulangan (pagi, siang dan malam). Pengolahan data menggunakan program SPSS 25 dengan analisis regresi liner berganda. Konsentrasi nitrat yang didapatkan berkisar antara 0,45-9,64 mg/l, konsentrasi fosfat berkisar antara 1,26-4,81 mg/l, kelimpahan fitoplankton berkisar antara 1.667 – 275.833 ind/l. Hubungan antara konsentrasi nitrat dan fosfat dengan kelimpahan fitoplankton tergolong lemah dengan koefisien korelasi (r = 0,378). Nitrat dan fosfat mempengaruhi kelimpahan fitoplankton sebesar 15% dengan koefisien determinasi (r square = 0,150). Tingkat kesuburan di Waduk Jatibarang termasuk dalam kategori mesotrofik hingga eutrofik berdasarkan konsentrasi nitrat, fosfat dan kelimpahan fitoplankton. ABSTRACT Jatibarang Reservoir is one of the reservoirs that has an important role in the city of Semarang so that the quality of its waters needs to be considered. The presence of phytoplankton in waters is closely related to the fertility and quality of a waters because phytoplankton act as primary producers. The purposes of this research are to determine the quality of water based on the consentration of nitrate and phosphate, to calculate the abundance of phytoplankton and also to know the correlation of nitrates and phosphate toward the abundance of phytoplankton. The research was conducted on 27 March 2019 in Jatibarang Reservoir Semarang. Sampling was carried out at seven stations with three depth points (surface, middle and bottom) and three repetitions (morning, day and night). Data processing using SPSS 25 programme with multiple liner regression analysis. The concentration of nitrate gained ranged from 0.45 - 9.64 mg/l, phosphate concentrations ranged from 1.26 - 4.81 mg/l, the abundance of phytoplankton ranges between 1,667 – 275,833 ind/l. The relationship between nitrate and phosphate concentrations with an abundance of phytoplankton is relatively weak with a correlation coefficient (r = 0.378). Nitrates and phosphates affect the abundance of phytoplankton by 15% with coefficient of determination (r square = 0.150). Water’s trophic state in the Jatibarang reservoir belongs to the mesotrophic up to Eutrophic category.
