Published: September 2019

Introduction: Different developmental and environmental vulnerability conditions can influence violent behavior in young people.Objectives: To describe the characteristics of young males who were convicted of murder or attempted murder in the province of Buenos Aires, based on indicators of maturity, impulsivity, and socio-family vulnerability.Materials and Methods: Descriptive and exploratory study. The sample consisted of 195 young men (mean: 16.8 years) imprisoned in reformatory institutions of the Province of Buenos Aires, Argentina, as they were convicted of murder (n=130), repeated murder (n=15), or attempted murder (n=50). Self and hetero-informed instruments, and professional assessment scales were used, namely: the Consideration of Future Consequences Scale (CFC); the Psychosocial Maturity Inventory (PSM); the Weinberg Adjustment Inventory (WAI); the Resistance to Peer Influence Questionnaire (RPIQ); the Psychopathy Checklist: Youth Version (PCL:YV); the Inventory of Callous Unemotional Traits (ICU), and the Barrat Impulsiveness Scale version 11 (BIS-11).Results: The distribution of the total BIS 11 and the PSM Individual Adaptation were normal (mean: 62.33 and 6.38, respectively). The mean of the total PCL:YV was 25.87. In 32.8% of the cases a first degree relative was also imprisoned. “Impulsive” and “Nonimpulsive” clusters were empirically established.Conclusions: The participants’ profile is characterized by several psychological and socio-family vulnerabilities that should be targeted in preventive interventions aimed at preventing violent recidivism.

Authors: Kheirabadi M. , Nabipour A. , Dehghani H. , Behnam-Rasuli M.
Published: September 2019

In this study, the ultrastructural development of germ cells in the ostrich embryo was analysed. The nuclear organisation and morphological characteristics of cytoplasm in the developing germ cells, on embryonic days 20, 26, and 36 and the day of hatching (5 samples from each stage) was analysed using transmission electron microscopy (TEM). Germ cells located in the cortex of left ovaries were identified by their large size and centrally located nucleus, with a conspicuous nucleolus. In these cells, the cytoplasm contained an abundance of mitochondria and free ribosomes. The structure of Balbiani body, a villous-like elevation in wide intercellular space and desmosome junction between two adjacent germ cells was also studied. The germ cells during embryonic development showed structural differences in both the nucleus and cytoplasm.
Effects of a 1,2,4-triazole derivative liposome emulsion on the innate and adaptive immunity of puppies vaccinated against canine parvovirus and canine distemper
Authors: Broshkov M. , Kichun I.
Published: September 2019

The aim of the study was the evaluate the immunomodulating effect of a 1,2,4-triazole derivative liposome emulsion (Trifuzol) in puppies vaccinated against parvovirus enteritis and canine distemper. The used Trifuzol liposome emulsion led to a significant increase in the absolute number of lympho-cytes and their immunoregulatory subpopulations, phagocytic activity of neutrophils. The level of antibodies against parvovirus enteritis (CPV) and canine distemper (CDV) in vaccinated and Trifuzol-treated puppies reached zero values which were statistically significantly lower than those in vac-cinated-only puppies (21.0 U/mL and 27.0 U/mL, respectively). It was concluded that the tested liposome emulsion of Trifuzol had an positive effect on the humoral immunity in puppies and can be used in clinical practice as an immunomodulatory agent.

Authors: Kandil O. , Hassan N. , Sedky D. , Beshir Ata E.
Published: September 2019

Cystic echinococcosis (CE) is of increasing public health and socio-economic concern because of the large morbidity rates and produced high economic losses in the livestock industry. The objective of the current research was to study the reliability of indirect ELISA in detecting CE, based on two dif-ferent types of crude antigens of camel origin; protoscolex and germinal layer antigens from hydatid cyst. Blood samples were collected from 284 (125 slaughtered and 159 live camels). Out of 125 slaughtered camels examined visually, 55 (44%) were found to have hydatid cysts. Of them, 52/125 (41.6%) and 3/125 (2.4%) harboured hydatid cysts in lungs and livers respectively. Fertile lung cysts were 32.8%; 26.9% were sterile, while 40.3% of lung and liver cysts were calcified. The sensitivity of ELISA was 83% and 46.5% when protoscolex and germinal layer antigens were used, respectively. The respective speciﬁcity of antigens of protoscolex and germinal layer was 70.3% and 41.7%. The protoscolex antigen showed higher accuracy (73.6%) compared to the germinal layer antigen (52.8%). The cross reactivity of these antigens were evaluated with antigens and hyperimmune sera of CE and Fasciola spp. and Haemonchus contortus using ELISA. The results showed also weak immunogenic potency of each antigen with Fasciola spp. hyperimmune sera at dilution 1:50 while hyperimmune sera of Haemonchus contortus did not bind any antigen.
Incorporating sprouted chickpea flour in pasta increases brachial artery flow-mediated dilation
Authors: Bruno JA , Feldman CH , Konas DW , Kerrihard AL , Matthews EL
Published: September 2019

Purpose

Consumption of alternative flours, such as sprouted chickpea flour, has shown increased popularity in recent years. Foods rich in antioxidants have been shown to influence brachial artery flow-mediated dilation (FMD), a non-invasive test of a crucial layer of the artery called the endothelium. Partially replacing the semolina flour in pasta with sprouted chickpea flour (SCF) may acutely affect endothelial function post-digestion. We sought to determine if FMD was higher, lower, or the same post-digestion of pasta made with 60% semolina flour and 40% SCF (SCF40) vs. post-digestion of pasta made with 100% semolina flour (SEM100, i.e., control).

Methods

Trolox equivalent antioxidant capacity (TEAC) analysis was performed on the same flour samples. Healthy participants underwent a screening visit and two randomized controlled meal data collection visits (SCF40 and SEM100). At each data collection visit, participants consumed 255 g of pasta with butter. FMD was assessed 2–3 h after pasta consumption.

Results

TEAC results showed that SCF40 (2.031 ± 0.096 mmol trolox/100 g sample) had significantly greater antioxidant capacity than SEM100 (1.736 ± 0.046 mmol trolox/100 g sample; p = 0.02). Twenty-two healthy participants (5 men and 17 women; 26 ± 2 years, 66.6 ± 2.3 kg, BMI = 24 ± 1 kg/m2, SBP = 114 ± 3 mmHg, DBP = 75 ± 2 mmHg, HR = 74 ± 3 BPM) were studied. FMD in the SCF40 condition (10.3% ± 1.2%) was greater than the SEM100 condition (7.9% ± 0.8%, p = 0.02).

Conclusion

These data suggest that partial substitution with sprouted chickpea flour in place of semolina flour in pasta acutely improves post-digestion FMD, which may be beneficial for cardiovascular health (ClinicalTrials.gov Identifier: NCT03801486).

Comparative analysis of selected databases of spatial information systems, with the view to meeting the needs of real estate property valuation in Poland — a case study
Authors: Jurkiewicz Magdalena
Published: September 2019

This publication is a case study on the analysis of the level of detail of the selected Local
Spatial Information System in Poland, in terms of the content of databases and the possibil-
ity of using them in property valuation. The scope of research covered in particular the Spatial
Information System (SIS) for the city of Częstochowa, operating as part of a project co-financed
by the European Union from the European Regional Development Fund under the Regional
Operational Program of the Silesia Region for the years 2007–2013. The main purpose of im-
plementing this system is to increase the availability and scope of public services provided elec-
tronically, as well as to simplify and speed up administrative procedures. In this publication, we
present results of research that was carried out in order to determine the suitability of informa-
tion collected in the analysed system for the purposes of preparing an appraisal (property valua-
tion) report by a property appraiser. The case study contains a comparative analysis of informa-
tion available in the Częstochowa spatial information system with similar systems operating in
several selected cities. These include the SIS for Kraków, Wrocław and the capital city of Warsaw.
Studies have shown that Kraków’s city portal is the most useful in terms of property valuation
needs, while the information contained in the Częstochowa spatial information system is not
sufficient.
Fast Punicalagin Content Analysis of Various Brands of Pomegranate (Punica granatum L.) Juices by UPLC-MS
Authors: SOLAKYILDIRIM Kemal
Published: September 2019

Punica granatum L., commonly known as pomegranate, has a good source of bioactive polyphenolic compounds that

has been widely used as a traditional Chinese herbal medicine owing to their important biological properties including

cardiovascular disease, arthritis, diabetes, and cancer. Commercial pomegranate juice is generally obtained via pressing

whole pomegranate and its peels. Then, the most abundant ingredient, punicalagin, can be extracted into the juice. However, punicalagin levels may vary in commercial pomegranate juice and it can range from 0.017 to 2 g/L. In this study, we

analyzed punicalagin content from six different brands of pomegranate juices by using UPLC-MS method. First, punicalagin

standards were prepared from 50 µM to 5 µM in buffer A (0.1% formic acid in water) and standard calibration curve was

created. After that, three mass tune parameters including ionization voltage, desolvation temperature and source temperature of ESI source were optimized to obtain better peak shapes and correct quantification of the α- and β- isomer peaks of

punicalagin. After analysis of six different brands of pomegranate juices, it was seen that punicalagin levels from different

juice samples varied from 0.007 to 0.3 g/L.
Evaluation of Drought Tolerant Top Cross and Three-Way Cross Maize Hybrids for Grain Yield and Related Traits in Three Agro-Ecological Zones of Southwest Nigeria
Authors: FAYEUN Lawrence , SESAY Sayo
Published: September 2019

Superiority of hybrid maize cannot be overemphasized. Different types of hybrids are developed by plant breeders to improve productivity and multi-locational evaluation of these hybrids prior to release is necessary to select the best. The objectives of this study were to identify maize hybrids with superior agronomic potentials and compare the performance of top-cross and three-way cross hybrid maize varieties for grain yield and related traits under rain-fed condition in three different locations (Abeokuta, Ibadan and Akure) of Southwest Nigeria. The study consisted of ten hybrids each of top-cross and three-way cross hybrid varieties, tested with two checks. At each location, the experiment was laid out in randomised complete block design with three replications. The results showed that effects of locations, genotypes and genotype x location interactions were highly significant (p<0.01) for all the traits evaluated. Significant differences were also revealed between the top-cross and three-way cross hybrids for all the traits evaluated except days to 50% tasseling, ear diameter and 100-grain weight. The top-cross hybrids were superior over the three-way cross hybrids for grain yield by 5.25%. The hybrids ‘M0926-7’, ‘M0926-8’, ‘M1026-11’, ‘M1026-3’, ‘M1226-2’ (top-cross hybrids), ‘M1124-24’, ‘M1124-27’, ‘M1124-31’, ‘M1227-6’ and ‘M1227-7’ (three-way cross hybrids) showed highest stable yields across the three locations.  Hybrids ‘M0926-7’ (top-cross hybrid) and ‘M1124-24’ (three-way cross hybrid) that expressed early flowering with higher grain yield are recommended for drought stress prone areas because of their abilities to tolerate drought through escape.

Published: September 2019

The present study aimed to evaluate antimicrobial activity of ethanol, methanol, schnapp (40% alcohol), oil palm wine and Raffia palm wine extracts of moss species Archidium ohioense, Pelekium gratum and Hyophila involuta against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Candida pseudotropicalis. The antimicrobial activities of the alcoholic extracts were tested against selected microorganisms using agar well diffusion method. Minimum inhibitory concentrations (MIC) of the extracts were determined using standard methods. The antimicrobial test of the extracts on selected organisms revealed that the methanolic and ethanolic extracts of the mosses studied were inactive against all the bacteria and fungi screened, while the schnapp, Oil palm wine and Raffia palm wine extracts showed significant activity against the selected organisms. The minimum inhibitory concentration (MIC) value of the extracts on the test organisms ranged from 1.25 to 40 mg/ml. The study concluded that the extracts of the mosses studied contain pharmacologically active constituents which may be responsible for their antimicrobial properties.

Published: September 2019

Oral hygiene is important to the generality of the human healthcare system. For this, the antifungal activities of the aqueous and ethanol extracts of four medicinal plants of Jatropha curcas (stem), Eucaluptus golbulus (leaves), Vernonia amygdalina (stem) and Zanthoxylum zanthoxyloides (root) were carried out in vitro against three species of Candida associated with oral thrush namely C. albicans, C. glabrata, C. tropicalis using the disc diffusion agar assay. The zones of inhibition varied with the test organisms as well as the extracts. The ethanolic extract of Jatropha curcas showed the highest zone of inhibition of 10.88 ± 0.22 mm against C. albicans while the least zone of inhibition (6.13 ± 0.13 mm) was exhibited by the ethanol extract of Z. zanthoxyloides on C. glabrata. The preliminary phytochemical screening showed the presence of tannin, saponin, alkaloids, flavonoids and reducing sugar in all plant samples. This study can be further used as a foundation for the screening of phytochemical constituents by pharmaceuticals for the control and eradication of oral thrush.
Economicrealizationofpropertythroughcooperation

Published: September 2019

The economic realization of property in a market economy is also manifested in a special form of organization of economic activity and entrepreneurship – cooperation. When organizing business through cooperation, a more vague alienation of the worker from the means of production is manifested, which allows to optimally resolve the contradiction between labor and capital. Around the world, most cooperative enterprises are based on various modifications of communal-collective ownership. In the conditions of modern Russia, in order to overcome the economic lag and import substitution, the transition to full-fledged market relations, the further development of ownership forms, the cooperative form of economic management is becoming increasingly important.
The growing number of cooperative entrepreneurship contributes to de-monopolization and the development of healthy competition, increasing the level of consumer protection, increasing the number of jobs and reducing unemployment, creating a layer of collective owners as a social basis for the stable development of society and the welfare of the population. An analysis of numerous publications on the issue of cooperation in recent years suggests that representatives of cooperative management, without demanding large capital and production facilities, know-how and serious experience in manufacturing products with special consumer qualities, are created by their economic nature for "Start from scratch".
In the article, the co-authors investigated issues related to the economic form of realization of property through cooperation. Questions concerning the history of the cooperative movement, foreign and Russian experience in the functioning and development of various forms of cooperation are considered.

Background

Bevacizumab, a VEGF-A inhibitor, in combination with chemotherapy, has proven to increase progression-free survival (PFS) and overall survival in multiple lines of therapy of metastatic colorectal cancer (mCRC). The angiogenic factor angiopoetin-2 (Ang-2) is associated with poor prognosis in many cancers, including mCRC. Preclinical models demonstrate improved activity when inhibiting both VEGF-A and Ang-2, suggesting that the dual VEGF-A and Ang-2 blocker vanucizumab (RO5520985 or RG-7221) may improve clinical outcomes. This phase II trial evaluated the efficacy of vanucizumab plus modified (m)FOLFOX-6 (folinic acid (leucovorin), fluorouracil (5-FU) and oxaliplatin) versus bevacizumab/mFOLFOX-6 for first-line mCRC.

Patients and Methods

All patients received mFOLFOX-6 and were randomized 1:1 to also receive vanucizumab 2,000 mg or bevacizumab 5 mg/kg every other week. Oxaliplatin was given for eight cycles; other agents were continued until disease progression or unacceptable toxicity for a maximum of 24 months. The primary endpoint was investigator-assessed PFS.

Results

One hundred eighty-nine patients were randomized (vanucizumab, n = 94; bevacizumab, n = 95). The number of PFS events was comparable (vanucizumab, n = 39; bevacizumab, n = 43). The hazard ratio was 1.00 (95% confidence interval, 0.64–1.58; p = .98) in a stratified analysis based on number of metastatic sites and region. Objective response rate was 52.1% and 57.9% in the vanucizumab and bevacizumab arm, respectively. Baseline plasma Ang-2 levels were prognostic in both arms but not predictive for treatment effects on PFS of vanucizumab. The incidence of adverse events of grade ≥3 was similar between treatment arms (83.9% vs. 82.1%); gastrointestinal perforations (10.8% vs. 8.4%) exceeded previously reported rates in this setting. Hypertension and peripheral edema were more frequent in the vanucizumab arm.

Conclusion

Vanucizumab/mFOLFOX-6 did not improve PFS and was associated with increased rates of antiangiogenic toxicity compared with bevacizumab/mFOLFOX-6. Our results suggest that Ang-2 is not a relevant therapeutic target in first-line mCRC.

Hacia la felicidad laboral: atender motivaciones y eliminar «temores digitales»
Authors: Foncubierta Rodríguez María_José , Sánchez-Montero Juan-Manuel
Published: September 2019

Considerando la motivación como integrante básico de la gestión de la felicidad en el trabajo, se analiza la valoración de determinados componentes de la misma en la era digital a partir del concepto de factor motivacional e higiénico de Herzberg. Se comprobará si existe alguna asociación entre el perfil sociodemográfico del trabajador y ciertos factores a “higienizar”. En una muestra de empresas de la Bahía de Algeciras (España), y mediante cuestionario, se recogen las opiniones de los trabajadores con respecto a dichos componentes. Se confirma que los factores motivacionales propuestos son altamente valorados. La falsedad de datos, el miedo a ser sustituidos en las tareas y la despersonalización del trabajo son las cuestiones más temidas, cuya ausencia hay que procurar. Se percibe, también, asociación de determinadas variables sociodemográficas del trabajador con el grado en que se manifiestan alguno de esos temores. La originalidad principal de este trabajo estriba en que se aportan y analizan factores, motivacionales e higiénicos de nueva aparición en lo laboral, que, como tales, habrán de ser gestionados.

El crecimiento económico como modelo de desarrollo social y su relación con el cambio climático
Authors: Rodríguez Pérez de Agreda Gabriel Modesto , Cabalé Miranda Elizabeth , Deroy Dominguez Dania
Published: September 2019

El presente artículo analiza cómo desde el pensamiento crítico se abordan las complejas relaciones entre crecimiento económico, como modelo de desarrollo social imperante y el cambio climático. En este sentido, el cambio climático se presenta como el cambio global más gravitante al cual se enfrenta la humanidad, y donde a pesar de las medidas adoptadas, aun la posibilidad de desastre es real. Tomando como referencia a los clásicos, realiza un breve análisis de la relación Capital-trabajo. Brinda una mirada en un horizonte de proyección, donde junto a las imprescindibles medidas de mitigación y adaptación al cambio climático se asumen otras asociadas a la emancipación humana. Igualmente desde el análisis de algunos de los documentos normativos de los últimos años se hace un acercamiento a la importancia de la educación como factor esencial para lograr detener este proceso. Se realiza una mirada crítica y cuestiona las distintas soluciones o propuestas relacionadas con el cambio climático. Al concluir se aprecia la necesidad de un cambio en este modelo de relaciones, fundamentalmente entre el ser humano y la naturaleza, para lograr la total emancipación. Además se propone la educación como una de las herramientas más importantes como factor de cambio y donde el ser humano debe ser parte activa de este proceso de cambio.
Criptomonedas y blockchain en el turismo como estrategia para reducir la pobreza
Authors: Barrutia Israel , Urquizo Maggia José Antonio , Acevedo Samuel Isaias
Published: September 2019

La pobreza en América Latina y el Caribe sigue siendo un problema sin aparente solución. Se propone en este artículo el uso de las criptomonedas y la tecnología de blockchain como una herramienta para reducir la pobreza en la región mediante actividades económicas provenientes del turismo. Para ello se efectuó un análisis detallado de las potencialidades que recogen en conjunto el turismo, las criptomonedas y la tecnología blockchain.   Dada las capacidades turísticas de las regiones latinoamericana y caribeña se debe concretar un conjunto de esfuerzos por parte de los gobiernos y empresas privadas en implementar el desarrollo turístico en regiones y localidades con gran biodiversidad y recursos naturales y culturales aún sin explorar. La relativa facilidad de acceso a cuentas bitcoin mediante teléfonos inteligentes hace que las transacciones financieras mediante criptomonedas se encuentran al alcance pequeños comerciantes que, normalmente, no tienen acceso a cuentas bancarias tradicionales. Por otro lado debe fortalecerse aún más el acceso a internet vía telefonía móvil para facilitar los sistemas de pago y para que las tecnologías basadas en blockchain puedan desarrollarse a su máxima capacidad. Se concluye que para lograr una significativa reducción de la pobreza es necesario la confluencia de una adecuada regulación de las criptomonedas por parte de los Gobiernos así como también el desarrollo una infraestructura adecuada que permita la creación y/o recuperación de microempresas potenciadas por la “Oferta Inicial de Monedas”.

An analysis of multimodal resources in environmental protection posters
Authors: Dallyono Ruswan , Sukyadi Didi
Published: September 2019

Exposure of environmental issues is essential to prevent mass environmental destructions; therefore, campaigns (posters) should be able to activate the viewers’ contemplation on such issues. The emergence of multimodal texts provides a vast opportunity for semioticians to do their analyses in a more creative manner in current communication processes. Accordingly, this study focuses on the interactive meanings of semiotic resources in posters on environmental campaigns using a multimodal perspective. It examines the contribution of visual and textual resources to raise people’s awareness on the significance of preserving the environment for future generations. This study drew upon analytical tools from SFL, social semiotics, and reading images (Bezemer & Kress, 2008; Kress, 2011; Kress & Van Leeuwen 1996; Martinec & Salway, 2005).  This form of contemplation can be considered to be a part of an essential educational process to build a good character. This study shows that the sample posters are significant to represent and transfer environmental messages through these multimodal resources.

Published: September 2019

Este estudo apresenta o processo de desenvolvimento e os estudos psicométricos iniciais da Escala das Dimensões do Desenvolvimento Identitário (DIDS), um instrumento que avalia os processos de desenvolvimento da identidade. Participaram no estudo 403 indivíduos (15-29 anos), que responderam a um questionário de dados sociodemográficos, à DIDS e ao Inventário da Sintomatologia Psicológica (ISP). Foram analisadas as características psicométricas da DIDS. Para o estudo da validade de construto foi realizada uma análise fatorial confirmatória. As validades convergente e discriminante foram analisadas através: da Variância Extraída Média (VEM); da comparação dos valores de VEM com os valores de correlação ao quadrado entre os fatores; e das correlações entre os processos de desenvolvimento da identidade e o ISP. A DIDS apresentou índices satisfatórios de fiabilidade compósita e consistência interna e a estrutura fatorial proposta foi confirmada. Os resultados sugerem que o instrumento poderia tornar-se mais fiável com o aumento do número de itens em alguns fatores e a eliminação de alguns itens existentes. No entanto, a DIDS é um instrumento passível de ser usado na medição do desenvolvimento identitário em adolescentes e adultos emergentes portugueses.

Authors: Lages Ana , Magalhães Eunice , Antunes Carla , Ferreira Célia
Published: September 2019

This study aims to provide evidence of validity and reliability of the Social Well-being Scales in the Portuguese context. A cross-sectional study was developed with 322 adults (M = 30.45; SD = 8.52) aged from 18 to 58 years old, mostly females (65.8%). Confirmatory factor analysis revealed a good model fit considering the five-factor model consistent with the original theoretical proposal. Also, additional validity evidence was obtained with statistically significant associations being found between social well-being dimensions and satisfaction with life, depression and anxiety. Reliability data also showed adequate internal consistency of all well-being dimensions. This reliable and valid scale is useful to evaluate social well-being in adulthood in the Portuguese context, not only allowing a more comprehensive approach to the mental health research but also providing opportunities of assessment and intervention focused on a positive framework.

Authors: Mónico Lisete , Pais Leonor , Pratas Inês M. , Dos Santos Nuno R.
Published: September 2019

Sendo a liderança uma das temáticas que mais atenção tem recebido por parte dos investigadores das Ciências Sociais, o objetivo deste estudo é identificar e interpretar as representações sociais do chefe ideal entre portugueses. Para o efeito, foram inquiridas 2725 pessoas. Recorremos à Técnica de Associação Livre de Palavras para aceder às evocações do chefe ideal. Estas foram classificadas através do Quadro de Quatro Casas em função do seu valor significativo, possibilitando a identificação dos seguintes elementos constituintes do núcleo central: “compreensivo”, “respeitador”, “líder”, “simpático” e “competente”. Foi analisada a invariância do núcleo central em função das variáveis sexo, idade e ocupação de um cargo de chefia. Os resultados sugerem alguma aproximação semântica aos modelos de liderança positiva e virtuosa com o que a nossa amostra definiu como sendo o chefe ideal.

A amostra foi constituída por 202 adultos, com idades entre os 18 e os 68 anos, oriundos de várias regiões de Portugal Continental e Ilhas. Avaliaram-se neste estudo, questões sociodemográficas; dois aspetos do auto-esquema da aparência; o investimento esquemático, a autoconsciência da aparência; e os afetos positivos e afetos negativos. A análise fatorial exploratória permitiu a identificação da estrutura fatorial subjacente, confirmando os itens de cada dimensão. Os resultados sugerem índices de consistência interna adequados em ambas as dimensões, verificando-se a homogeneidade das variáveis. A análise fatorial confirmatória apresentou bom ajustamento, apontando para um modelo ajustado a dois fatores, composto por 13 itens. A CARSAL/CARVAL, apresenta-se como um instrumento psicometricamente robusto, na avaliação dos dois aspetos do auto-esquema da aparência (saliência/valência).
Reinterpreting Existenzminimum in Contemporary Affordable Housing Solutions
Authors: Brysch Sara
Published: September 2019

During the housing crisis of the 1920s, the German concept Existenzminimum (minimum dwelling) was developed and applied to the construction of public social housing. It was considered a design laboratory, where research, design, and experimentation would focus on a unique goal: create a space-efficient affordable housing typology, based on minimum quality standards. Empirical evidence indicates a renewed interest in alternative design solutions and minimum dwelling approaches over the last decade: examples include micro-housing solutions and collaborative housing models. This is due to the current affordable crisis and the increasing trend of urbanisation. However, little is known about the current interpretation of Existenzminimum. What does the concept entail today and how has it developed? This article investigates if and how Existenzminimum is currently applied: first, it unfolds the core design principles of the original Existenzminimum. Then, these principles are used to assess if and how existing affordable or low-cost housing approaches are current (re)interpretations of the concept. Finally, the article proposes a definition for a contemporary Existenzminimum, arguing that a better understanding and awareness of the concept can help urban planners, designers, policy-makers and citizens in developing alternative affordable housing solutions.
Between Rationalization and Political Project: The Existenzminimum from Klein and Teige to Today
Authors: Korbi Marson , Migotto Andrea
Published: September 2019

A critical reflection on the II CIAM (Congrès Internationaux d’Architecture Moderne; in Frankfurt, 1929) should not limit itself to a purely historiographic reconstruction. The article discusses the II CIAM reflection on the Wohnung für das Existenzminimum (dwelling for the minimum level of existence) by means of a comparison between the official positions of participants and those of two architects, Alexander Klein and Karel Teige, who gravitated around the Frankfurt and Brussels meetings. The confrontation will unlock a double scenario. On the one hand, it will depict a multifaceted and more precise account of the discussion developed in the late 1920s on the minimum dwelling, integrating CIAM discussions with alternative theories and methods developed to face housing shortage and degraded living conditions. Investigating the impact of socio-economic conditions on household forms of life, Klein and Teige presented two paradigmatic and autonomous approaches that tackled the traditional solutions of architecture for the Existenzminimum. On the other hand, we argue that a broadened revision of the themes discussed at the end of the 1920s, namely the transformation of household compositions, the criticism of the paradigms of liberal urban development, the relation between production and forms of life as well as the position of the architect in housing production, proves to be useful for the understanding and overcoming of the fragmentation that still nowadays characterizes the reflection on domestic space.
