Authors: Ruiz Manuel Chavez , Camargo Betsabe Ruffner , Torres Lenin Rueda , Bellido Cristofer
Published: May 2021

Objetivo. En el presente trabajo se ha desarrollado una metodología para la evaluación de la protección respiratoria en mascarillas quirúrgicas y respiradores de uso común en la población peruana, considerando las partículas de mayor probabilidad de contener virus activo del SARS-COV-2, la cual incluye la capacidad de filtración del material empleado y el ajuste proporcionado por el dispositivo de protección respiratoria.

Metodología. Se ha determinado una relación lineal directa entre el logaritmo de la concentración de partículas suspendidas en aire y el tiempo transcurrido; por lo cual es posible comparar la cantidad de partículas internas y externas a la mascarilla o respirador en un mismo período de tiempo y conocer el porcentaje de protección respiratoria de cada muestra evaluada.

Conclusiones: Se obtiene concordancia entre los valores obtenidos de protección respiratoria y los esperados considerando el nivel de filtración del material empleado que compone cada mascarilla quirúrgica o respirador, y el nivel de ajuste presentado por los mismos, observándose un incremento significativo en los niveles de protección respiratoria mejorando el ajuste en los mismos.
The precuneal cortex: anatomy and seizure semiology
Authors: Al‐Ramadhani Ruba R. , Shivamurthy Veeresh Kumar N. , Elkins Kathryn , Gedela Satyanarayana , Pedersen Nigel P. , Kheder Ammar
Published: May 2021

The purpose of this review is to describe the functional anatomy of the precuneal cortex and outline some semiological features of precuneal seizures. The precuneal cortex is a structure that occupies the posterior medial portion of the parietal lobe, and it has broad cortical and subcortical connections. Neuroanatomical tracing, functional imaging, as well as electrical stimulation studies of humans and other primates have elucidated many complex integrative functions of the precuneus including visuo‐spatial imagery, sensorimotor functions, and consciousness. Based on the understanding of its functions and connectivity, descriptions of potential seizure semiologies are hypothesized and compared to what is available in the literature. The latter is mostly in the form of case reports or case series. Seizures may involve simple or complex motor or sensory manifestations including abnormal eye movements, visual hallucinations, sensation of motion, or medial temporal‐like seizures.
An Ultrasound-Assisted Approach to an Early Detection of Complications of an Implant-Based Augmentation Mammaplasty using the BellaGel® SmoothFine: Preliminary 3-year Clinical Experience
Authors: KY Song , JY Sung , WS Choi , HG Lim , JH Kim
Published: May 2021

Background: Selection of optimal types of breast implants is an essential factor that determines the degree of patients’ satisfaction with outcomes of augmentation mammaplasty, for which an evidence-based approach to it is mandatory. Several studies have supported the safety of the BellaGel® SmoothFine (HansBiomed Co. Ltd., Seoul, Korea), a silicone gel-filled breast implant from a Korean manufacturer. But such studies have been conducted in a manufacturer-sponsored setting. We therefore conducted this non-manufacturer-sponsored, retrospective study to assess its 3-year safety outcomes in Korean women.
Terminologie comparée et traduction

Comment garantir la précision scientifique exigée par les spécialistes des différents domaines du savoir ? s’interroge le terminologue. Par quel moyen peut-on cautionner la fidélité en traduction lors du transfert d’un message scientifique d’une langue à l’autre ? se demande le traducteur. Voilà les questions qui rapprochent les réflexions menées par les acteurs des deux domaines : la terminologie et la traduction. Mais paradoxalement, c’est de ces mêmes interrogations qu’émergent des divergences quant aux moyens à employer et aux objectifs à atteindre. Prenant appui sur le fonds théorique de chacune des deux disciplines, sans pour autant négliger les démarches méthodologiques, Héba Medhat-Lecocq apporte des réponses aux questions qui interpellent sans cesse les chercheurs issus de ces deux horizons, et qui œuvrent dans l’interdisciplinarité. Riche d’exemples empruntés aux deux langues, française et arabe, et traduits par l’auteure, le présent ouvrage a une vocation pédagogique, notamment pour les nouveaux chercheurs en terminologie, en traduction, mais aussi pour tous ceux qui s’intéressent à la langue et au discours spécialisés.

Residential Segregation and Unequal Access to Schools
Authors: Nieuwenhuis Jaap , Xu Jiayi
Published: May 2021

Socio-spatial inequality and school inequality are strongly related. Where people live affects the opportunities individuals have in life, such as the opportunity to send your children to a good school. The level of urbanisation is related to the number of options people have to choose good schools, so more urbanised areas likely offer more options for good schools. However, the families that can choose good schools are likely families with high income or education levels. Data for this study come from two waves of the Taiwan Youth Project (N = 2,893), which consists of two cohorts of students from 162 classrooms in 40 junior high schools in northern Taiwan. When school quality is proxied by socioeconomic status (SES), the results show that, in general, students from the most urbanised areas, wealthier parents, and higher-educated parents, are more likely to go to higher SES schools. However, the strongest effects are for higher income and higher-educated parents in the most urbanised areas. This suggests that in the most urbanised areas, families have the most options regarding school choice, and richer and more educated families are better able to circumvent school catchment areas, either because they can afford an address in a better catchment area or because they understand the importance of school choice.
The Relationship between Ethno-Linguistic Composition of Social Networks and Activity Space: A Study Using Mobile Phone Data
Authors: Silm Siiri , Mooses Veronika , Puura Anniki , Masso Anu , Tominga Ago , Saluveer Erki
Published: May 2021

This study is a contribution to the discussion on the ethnic segregation cycle, through the examination of individuals’ activity spaces—including residence and workplace—and from the perspective of social networks. Bridging social ties can be a key factor in higher minority inclusion and in breaking the vicious circle of segregation. We compare the spatial behaviour of two ethno-linguistic population groups living in Tallinn, Estonia’s capital city (Estonian-speaking majority and Russian-speaking minority), each of which have co- and interethnic social networks, through the use of mobile positioning (call detail records) and call-graph data. Among our main findings, we show firstly that interethnic social networks are more common for the Russian-speaking minority population. The probability of having an interethnic network is related to the ethno-linguistic composition of the residential district concerned; districts with a higher proportion of residents from another ethnic group tend to favour interethnic networks more. Secondly, the activity space is related to the ethno-linguistic composition of the social networks. Spatial behaviour is most expansive for Estonian speakers with co-ethnic networks, and most constrained for Russian speakers with co-ethnic networks. At the same time, speakers of Estonian and Russian with interethnic networks show rather similar spatial behaviours: They tend to visit more districts where the proportion of people from the other ethno-linguistic group is higher. Interethnic networks are therefore related to spatial behaviour, which can indicate interethnic meeting points and locations, something that is regarded as being important in assimilation and segregation cycle theories.
Market-Based Housing Reforms and the Residualization of Public Housing: The Experience of Lodz, Poland
Authors: Ogrodowczyk Agnieszka , Marcińczak Szymon
Published: May 2021

Housing inequality is one of the central topics in urban studies, and in the social sciences more broadly. It is also one of the most significant and visible aspects of socioeconomic inequality. Over the last three decades, the process of housing commodification has accelerated across western societies and, consequently, the public housing sector has contracted and become more closely associated with the poorest sections of societies in many cities. Over the same period, the political changes in Central and Eastern Europe have contributed to the dismantling and monetizing of state housing sectors at the forefront of broader social and economic transformations. Unfortunately, most recent studies on housing commodification and inequalities in Europe are confined to the national scale. The aim of this article is to detail the linkages between the position and functioning of public housing in Lodz (Poland) and the evolving socioeconomic profile of individuals and households that rely on public housing. This study relies on microdata (statistical information on individuals and households) from two national Polish censuses (1978 and 2002) and from household budget surveys (2003–2013). The main finding of our study is that ‘residualization’ is present in the public housing stock in Lodz and that the process gained momentum in the first decade of the 2000s.

Orientation to the Future of Gifted Primary Schoolchildren: Near and Far Goals
Authors: Kulagina I.Y. , Shumakova N.B.
Published: May 2021

The article presents research data on the attitude of gifted children aged 9-10 years to different ages, their ideas about the future, setting short-and long-term goals. There is a great creative potential of giftedness, but how much it will be realized when reaching maturity depends not only on cognitive sphere, but also on the characteristics of the personality. The psychological literature contains contradictory information about the personal characteristics of gifted children; there is very little data on such aspect of personal development as orientation to the future, which determines the relevance and novelty of the study. The study involved 96 children with IQ≥115, enrolled in grades 3 and 4 of the gymnasium for gifted children, and 104 children enrolled in grades 3 and 4 of the secondary school under the traditional program (Moscow). We used the modified method of B. Zazzo “Golden age”, the projective method “Unfinished sentences” and the method of M.V. Matyukhina, which allows us to determine educational motivation in primary school age. It is shown that the majority of primary school children prefer youth as the age period of maximum opportunities. Gifted children are less likely than their peers with normative intellectual development to set short-range goals of good and excellent studies, self-improvement in activities that require physical effort, and more goals related to filling the lack of emotional support. The area of long-range goals related to youth is wider for younger students. Gifted children have a more pronounced orientation to high material security and freedom in its various manifestations, to a lesser extent – to the traditional construction of life (work, family, children).
A Study On Effectiveness Of Competency Mapping Through Training AndDevelopment
Authors: Et. al. Dr. Saikumari V,
Published: May 2021

In today’s corporate world, many companies and organization are increasingly focusing on human capital as a competitive advantage in rapidly changing environment. Many successful companies realize that their employees are their greatest asset. Therefore, companies are increasingly investing in educating their own employees so that they can grow and change within the company and make it more profitable.

The range of training opportunities varies considerable from company to company so, when researching potential employers, it is important for job seekers who  care  about  this  to  investigate  the  level  and  type  of  training  provided  to employees.  After  employees  have  been  selected  for  various  positions  in  an organization,  training  them  for specific  tasks  to  which  they  have  been  assigned assumes greater importance.

     This study suggests the organization to implement more modern training methodologies, then to provide practical training to the employees and to provide specific learning assignments or projects for participants to improve on their competency gap.
The Empty Demand for Solidarity
Authors: Dillinger Lisa
Published: May 2021

In times of crisis, an increasing number of voices are being raised calling for solidarity. It can therefore be assumed that the ability to behave in solidarity is of public interest and should be cultivated. Can and must solidarity then be an educational goal and in what way could it be implemented? A first step in answering these questions is to determine the content of the concept of solidarity, which has been interpreted in many different ways. In this article, I follow Simon Derpmann’s understanding of solidarity in order to propose a pedagogical view based on it. Consequently, two educational goals can be named that are conducive to the cultivation of solidarity: First, moral identity as the assurance and commitment to one’s own moral convictions, and second, the ability to collaborate in order to pursue shared and common goals with others. Finally, there remains the question of whether solidarity has an intrinsic value for the education of subjects, or whether it is a political endeavor that has no educational ethical justification in pedagogical debates.
Can Solidarity be Taught?
Authors: Fichtner Sarah
Published: May 2021

In this essay I am addressing the question of whether solidarity is something that can be taught. It is based on experiences from my field research on NGOs working on education in the West African Republic of Benin and in Germany. What does it need for someone to become solidary, and what does it take to grasp the politics of solidarity? What happens to solidarity when it is instrumentalized, when solidarity campaigns are transformed into a ‘competition of care’? I understand solidarity to be first and foremost about relating to others, from a certain power position, driven by a common cause, while acknowledging the differences between those who show solidarity, and those they show it for. Solidarity as a relational process is as much about oneself as it is about the other and the relation in between. Inspired by the pedagogy of resonance and ChangeWriters methods for relationship work, I argue that as an educational practice and subject, solidarity needs to be experienced, reflected on, shared, discussed, and thus understood in its personal and political dimensions. For this to happen on a larger scale, we would not only need to let go of an instrumental vision of solidarity, but also of an instrumental vision of education.

Chronic venous insufficiency (CVI) comprises a complete spectrum of morphological and functional abnormalities of the venous system1 including any long-term functional and morphological alteration. CVI accounts for several abnormalities of the venous system. It is a highly prevalent disease that causes serious economic consequences, a decrease in the quality of life and can lead to serious complications. An exhaustive review was performed with the available literature, using the PubMed, ScienceDirect, Scopus and Cochrane databases from 2004 to 2021. The search criteria were formulated to identify reports related to chronic venous insufficiency. The pathophysiology of chronic venous insufficiency begins with chronic venous hypertension and the dilation of the vessel, this leads to a series of pathological changes in the venous wall and surrounding tissues, in advanced stages of CVI, skin lesions are associated with an increased proliferation of skin capillaries and microcirculatory abnormalities that may be the result of an altered level of factors responsible for the angiogenic response, such as vascular endothelial growth factor (VEGF), fibroblast growth factor 2 (FGF2) and angiostatin. In this review, updates on pathophysiology, clinic, diagnosis, classification and treatment of this disease are analyzed, with special emphasis on therapeutic options. Chronic venous insufficiency is a disease that affects the patient at several levels, mainly diminishing his/her quality of life. Currently there are various treatments ranging from habit modifications, pharmacological, to endovenous and surgical treatment.
Multi-Sessions Outcome for EEG Feature Extraction and Classification Methods in a Motor Imagery Task
Authors: Hrisca-Eva Oana-Diana , Lazar Anca Mihaela
Published: May 2021

The purpose of this research is to evaluate the performances of some features extraction methods and classification algorithms for the electroencephalographic (EEG) signals recorded in a motor task imagery paradigm. The sessions were performed by the same subject in eight consecutive years. Modeling the EEG signal as an autoregressive process (by means of Itakura distance and symmetric Itakura distance), amplitude modulation (using the amplitude modulation energy index) and phase synchronization (measuring phase locking value, phase lag index and weighted phase lag index) are the methods used for getting the appropriate information. The extracted features are classified using linear discriminant analysis, quadratic discriminant analysis, Mahalanobis distance, support vector machine and k nearest neighbor classifiers. The highest classifications rates are achieved when Itakura distance with Mahalanobis distance based classifier are applied. The outcomes of this research may improve the design of assistive devices for restoration of movement and communication strength for physically disabled patients in order to rehabilitate their lost motor abilities and to improve the quality of their daily life.
3D Human Activity Classification with 3D Zernike Moment Based Convolutional, LSTM-Deep Neural Networks
Authors: Özbay Erdal , Çınar Ahmet , Özbay Feyza Altunbey
Published: May 2021

In this paper, we propose a method for classification 3D human activities using the complementarity of CNNs, LSTMs, and DNNs by combining them into one unified architecture called CLDNN. Our approach is based on the prediction of 3D Zernike Moments of some relevant joints of the human body through Kinect using the Kinect Activity Recognition Dataset. KARD includes 18 activities and each activity consists of real-world point clouds that have been carried out 3 times by 10 different subjects. We introduce the potential for the 3D Zernike Moment feature extraction approach via a 3D point cloud for human activity classification, and the ability to be trained and generalized independently from datasets using the Deep Learning methods. The experimental results obtained on datasets with the proposed system has correctly classified 96.1% of the activities. CLDNN has been shown to provide a 5% relative improvement over LSTM, the strongest of the three individual models.
Machine Learning-Based Emotional Recognition in Surveillance Video Images in the Context of Smart City Safety
Authors: Li Pan , Zhou Zhaojun , Liu Qingjie , Sun Xiaoye , Chen Fuming , Xue Wei
Published: May 2021

The effective extraction of deep information from surveillance video lays the basis for smart city safety. However, the surveillance video images contain complex targets, whose expression changes are difficult to capture. The traditional face expression recognition methods or sentiment analysis algorithms have a poor application effect. Based on machine learning (ML), this paper explores the emotional recognition in surveillance video images in the context of smart city safety. Firstly, the potential textures of surveillance video images were extracted under multi-order double cross (MODC) mode, and the optical flow features of facial expressions were detected in these images. Next, a facial expression recognition model was constructed based on the DeepID convolutional neural network (CNN), and an emotional semantic space was established for the face images in surveillance video. The proposed method was proved effective through experiments. The research results provide a reference for emotional recognition in images of other fields.
Real-Time Obstacle Detection Based on Image Semantic Segmentation and Fusion Network
Authors: Liu Wei
Published: May 2021

During fruit production, the robots must walk stably across the orchard, and detect the obstacles in real time on its path. With the rapid process of deep convolutional neural network (CNN), it is now a hot topic to enable orchard robots to detect obstacles through image semantic segmentation. However, most such obstacle detection schemes are under performing in the complex environment of orchards. To solve the problem, this paper proposes an image semantic fusion network for real-time detection of small obstacles. Two branches were set up to extract features from red-green-blue (RGB) image and depth image, respectively. The information extracted by different modules were merged to complement the image features. The proposed network can operate rapidly, and support the real-time detection of obstacles by orchard robots. Experiments on orchard scenarios show that our network is superior to the latest image semantic segmentation methods, highly accurate in the recognition of high-definition images, and extremely fast in reasoning.

Published: May 2021

Internet of things (IoT) has a collection of multiple network-enabled devices like sensors, gateways, smartphones, and communication links (short and long ranges). Tremendous capacity of IoT system has made possible to monitoring and detection of epileptical seizures in real time. For this purpose, various smart devices and applications, helps to transmit information securely. Amalgamation of IoT with healthcare system provides opportunity to deal issues like security, detection of seizures and real time monitoring. The proposed model of cloud-enabled Health IoT system has been presented in this paper, gives the idea about monitoring of epileptical patients. For secured transmission of Electroencephalogram (EEG) data, digital watermarking technique has been used over two dimensional EEG data obtained through one dimensional EEG data by applying Short Time Fourier Transform (STFT). In this paper, watermarking of two dimensional EEG data has been done using discrete wavelet transform - discrete cosine transform (DWT-DCT) based Bacterial Foraging Optimization (BFO) technique and its performance has been figure out. Here, satisfactory watermarking performance in terms of Peak Signal to Noise Ratio (PSNR) 49.50 for class Z and 49.61 for class S EEG data along with Normalized Cross Correlation (NCC) 0.0039 for both classes of EEG data have been achieved.
HMM Based Language Identification from Speech Utterances of Popular Indic Languages Using Spectral and Prosodic Features
Authors: Sadanandam Manchala
Published: May 2021

Language identification system (LID) is a system which automatically recognises the languages of short-term duration of unknown utterance of human beings. It recognises the discriminate features and reveals the language of utterance that belongs to. In this paper, we consider concatenated feature vectors of Mel Frequency Cepstral Coefficients (MFCC) and Pitch for designing LID. We design a reference model one for each language using 14-dimensional feature vectors using Hidden Markov model (HMM) then evaluate against all reference models of listed languages. The likelihood value of test sample feature vectors given in the evaluation is considered to decide the language of unknown utterance of test speech sample. In this paper we consider seven Indian languages for the experimental set up and the performance of system is evaluated. The average performance of the system is 89.31% and 90.63% for three states and four states HMM for 3sec test speech utterances respectively and also it is also observed that the system gives significant results with 3sec test speech for four state HMM even though we follow simple procedure.

В данной работе одностадийным пламенным методом были синтезированы гидрофобные углеродные слои на поверхности речного песка. Полученный одностадийным методом песок является супергидрофобным с углом смачивания свыше 140°. Созданный супергидрофобный песок, покрытый сажей обладающей гидрофобными свойствами был исследован физико-химическими методами, такими как, сканирующая электронная микроскопия (СЭМ), энергодисперсионная рентгеновская спектроскопия (ЭДС). Гидрофобные свойства углеродных отложений были количественно оценены путем измерения угла смачиваниякапли воды, нанесенных на поверхность углеродной пленки. Для изучения свойств смачиваемости гидрофобных углеродных слоев было проведено капельное испытание воды. Полученный песок использован для отделения нефти от воды.

O presente artigo analisa a realidade e as condições de encarceramento dos detentos do estado de Alagoas. Como objetivos secundários, analisaremos a situação de encarceramento dos presos provisórios, os quais possuem, através de consulta prévia ao banco de dados da secretaria de segurança pública, um tempo de custódia indefinido, o que demonstra a necessidade de revisão das regras implícitas ao sistema penitenciário brasileiro. Tal revisão mostra-se necessária para evitar a violação dos direitos humanos, uma vez que os julgamentos são estendidos, o que acaba gerando outros problemas, como a superlotação. A falta de julgamento em período previsto em lei e as violências a que são submetidos no ambiente penitenciário são corriqueiras no cotidiano destes detentos. Sendo assim, este trabalho tem como objetivo contribuir na implementação de políticas públicas preventivas para esta população analisada neste trabalho. O perfil traçado compreende a dados do período de 2010 a 2020, observando fatores como idade, escolaridade, raça/cor, gênero e o tipo de crime cometido. Utilizamos a metodologia de pesquisa bibliográfica e de análise documental de dados estaduais oficiais, oriundos da secretaria de segurança pública do estado supracitado. A pesquisa constata a maçante presença de presos do sexo masculino, de condição social vulnerável, bem como constata que alagoas se destaca como um estado em que tais condições citadas anteriormente são recorrentes.
CONTROLE SOCIAL E SEGREGAÇÃO EM MASSA: DO RECUO DO ESTADO DO BEM-ESTAR SOCIAL PARA A INSTITUCIONALIZAÇÃO DO ESTADO PENAL
Authors: Amorim Neto João Braz
Published: May 2021

A partir das últimas décadas do século XX e do começo do século XXI, observamos uma assimilação e incorporação pela América Latina do modelo norte-americano de combate à criminalidade, o qual tem como elementos centrais um policiamento ostensivo aliado a um sistema penal repressivo rígido com um grande aumento no número de prisões. Concomitante a isso, também observamos um recuo das políticas de assistência social que foram historicamente incorporadas pela sociedade, que tinham o Estado como, além de regulador, responsável pela proteção social que ajudaria a combater as desigualdades sociais geradas pela expansão desordenada do capitalismo. Este trabalho tem como objetivo fazer uma análise macrossociologia sobre as práticas de controle social e segregação massiva à luz dos mecanismos engendrados pelas políticas de “tolerância zero” e de “lei e ordem”, a partir de uma perspectiva que dialogue com autores clássicos da sociologia como Karl Marx e Émile Durkheim.

Purpose of the study: The study aims to investigate the welfare of the citizens of Pakistan and to compare the traditional economic growth rate i.e. IWI with welfare indices i.e. ACEWI, ACPWI-I, ACPWI-II.

Methodology: For the welfare index, Ahluwalia and Chenery Welfare Index have been used to evaluate the welfare of the people in Pakistan. The study used time series data from 1990 to 2017.

Main Findings: Outcomes stated that the traditional measure of household income growth is far greater than the real growth rate which was measured through ACWI’s. Pakistan’s economy lacks equal distribution of income among different sections of the society because of government fiscal policy.

Novelty/Originality of this study: This investigation will provide the policymaker with proper guidance for developing a policy for the fair distribution of the resources to build the standard of living of every citizen in Pakistan.
Exploring Symbolic Meaning in Landscaping Choices within a Desert City

Metropolitan Phoenix, Arizona, in the Sonoran Desert, provides an excellent opportunity to understand residents’ preferences for desert-adapted xeric landscaping. While much is known about the relationships between sociodemographics and broad environmental values on xeric landscaping choices, the influence of other variables remains unexplored, especially interactions with and attachments to the desert. We therefore examined the influences of recreational visits to local desert mountain parks and symbolic meanings associated with the native desert on household xeric landscaping preferences. Within a larger study, select questions captured socio-demographics, visitation to desert parks and open spaces, place identity, and xeric landscape preferences. Using Ordinary Least Squares (OLS) regression, we confirmed that homeownership and a shorter residency predicted preference for xeric landscapes. Hispanics were less likely to prefer xeric landscaping. Interestingly, the novel factor of identity with the desert significantly and positively predicted xeric landscaping preference while visitation to desert parks and open spaces did not. Findings provide several important management implications. First, Phoenix has an opportunity to foster connections with the surrounding environment through its extensive desert mountain parks. Increasing connections between residents and the parks may help shift personal preferences to xeric yard types. Park managers might also work to further stress how household decisions can affect the desert environment. Second, park visitation alone may not suffice to create connections with the desert environment. Instead, park managers should focus on creating opportunities for visitors to recognize the unique, living aspects of the parks and build personal relationships with the ecosystem. Interpretation encouraging emotional connections to the desert environment may aid in fostering an identity with the desert. In addition, messaging and signage campaigns that link people to the parks may prove a novel way of combatting lawn water usage within desert cities. Given their opportunities to foster place identity, urban parks may be important influencers in promoting native plant landscaping. In conclusion, connecting people to their surrounding environments can influence preferences for similar landscape types at the household level.
Parkland Dedication: How are Cities Implementing the Rough Proportionality Principle?
Authors: Crompton John
Published: May 2021

As part of local governments’ mandate to regulate for the “health, safety, and general welfare” of their residents, many have included a parkland dedication exaction on new development in their sub-division regulations. The rules governing the magnitude of the dedication were established in 1994 by the U.S. Supreme Court in Dolan v City of Tigard. The Court ruled there must be “rough proportionality” between a dedication exaction and the projected new demand from a development. The ruling requires a local jurisdiction to be proactive in quantifying the justification for the magnitude of a dedication it imposes, but the Court offered no guidance on how the quantification should be done. This study’s two objectives were: (i) to investigate the extent to which cities’ ordinances comply with the Supreme Court’s ruling, and (ii) to identify best practices among cities’ ordinances relating to operationalizing the “rough proportionality” principle. Parkland dedication ordinances were analyzed from 73 Texas cities, supplemented by insights from those of 29 large cities outside Texas. In 65 of the Texas ordinances where “rough proportionality” comparisons could be made, the analyses found percentage under-dedications ranging from 9% to 1,250%. In defiance of the Court’s ruling, almost two-thirds of the ordinances showed no evidence of using an empirical quantitative method to establish “rough proportionality.” Many of these ordinances provided a service level ratio, but it appeared to be arbitrarily determined. These findings are especially egregious in Texas, since state law requires that the quantification of “rough proportionality” be certified as being appropriate by a professional engineer. Three models of best practice that used empirical methods to derive rough proportionality and met the Supreme Court guidelines are identified, described, and illustrated. Under-dedication often reflects the reluctance of elected officials to antagonize the development community. Thus, four strategies are offered to facilitate their efforts to impose a substantive exaction that relieves the burden on taxpayers, while demonstrating sensitivity to any protests arising from members of the development community.
