A 5-axis machining center (5MC) is noted for its synchronous control capability, making it a feasible tool for quickly and accurately machining complicated three-dimensional surfaces such as propellers and hypoid gears as it is equipped with a direct-drive (DD) motor in the rotary axis. The current research work identified the necessity of improving both the accuracy of the machined shape and the consistency of the free-form machined surface. A method for maintaining the feed speed vector at the milling point by controlling two linear axes and the rotary axis of a 5MC to improve the quality of the machined surface was investigated. Additionally, a method was proposed for reducing the shape error of machined workpieces by considering differences in the servo characteristics of the three axes. The shape error was significantly reduced by applying the proposed method using a precedent control coefficient determined via calculations. To maintain the feed speed vector at the milling point in the machining of complex shapes, rapid velocity change in each axis is often required, leading to inaccuracy caused by torque saturation at a DD motor in the rotary axis. The results of this study indicate that torque saturation can be evaluated via simulation and that the machining accuracy and consistency can be improved by accounting for these errors using the proposed precedent control coefficient method.

Objectives. To investigate the prognostic factors and treatment outcomes of primary parotid carcinoma treated with surgery and postoperative radiotherapy (PORT).Methods. We reviewed retrospectively 57 patients with primary parotid carcinoma who were treated with surgery and PORT between 2005 and 2014. Superficial parotidectomy was performed in 19 patients, total parotidectomy in 10 patients, and total parotidectomy with lymph node dissection in 28 patients PORT on the tumor bed was performed in 41 patients, while PORT on tumor bed and ipsilateral cervical lymph nodes was performed in 16 patients.Results. With a median follow-up of 66 months, the 5-year overall survival, disease-free survival, locoregional control, and distant control rates were 77.0%, 60.2%, 77.6%, and 72.8%, respectively. The 5-year overall survival by stage was 100%, 100%, 80.0%, and 46.4% in stage I, II, III, and IV, respectively. Recurrences at primary lesions were found in seven patients, while at cervical nodes in six patients. Distant recurrences were developed in 12 patients. No patient with the low and intermediate histologic grade developed distant failure. As prognostic factors, the histologic grade for overall survival (P=0.005), pathological T-stage (P=0.009) and differentiation grade (P=0.009) for disease-free survival, pathological T-stage for locoregional control (P=0.007), and lympho-vascular invasion (P=0.023) for distant recurrence were significant on multivariate analysis.Conclusion. This study revealed that differentiation grade, histologic grade, pathological T-stage, and lympho-vascular invasion were significant independent prognostic factors on clinical outcomes.

Embedding e-assessment in an effective way
Authors: Greenhow Martin
Published: September 2019

This opinion piece presents my experiences of using e-assessment for foundation year mathematics, analysing data from a 230-strong cohort. Strengths and weaknesses of using e-assessment are discussed, and I present two experiments that have been embedded this year to attempt to counteract poor mathematical skills and study attitudes amongst some students. Data from the last four years show that learning (as measured by end-of-year traditional exams) has been sustained. It seems probable that this is partly due to the efficacy of these measures, but results from the experiments in using staged tests and in appraising foundationers’ mathematical confidence are mixed.
Effective Marketing Strategies to Promote Engagement with Online Mathematics Learning Support
Authors: Guerin Aoife , Walsh Richard
Published: September 2019

In this paper we report on the effects of a different marketing strategy on promoting engagement with the online Mathematics Learning Support (MLS) service (mostly screencasts) compared to our traditional advertising approach which was solely to send generic emails to students advertising the online services. The findings show that this new marketing strategy was far more effective than traditional methods of advertising in getting students to engage with the online service. This paper describes the approach taken and compares the engagement with the online services offered by the Mathematics Learning Centre (MLC) before and after utilising the new marketing strategy, the increased engagement from the trial group with the online services compared to the other groups, and the knock-on effects.
The impact of peer assessment on mathematics students’ understanding of marking criteria and their ability to self-regulate learning
Authors: Brignell Chris , Wicks Tom , Tomas Carmen , Halls Jonathan
Published: September 2019

At the University of Nottingham peer-assessment was piloted with the objective of assisting students to gain greater understanding of marking criteria so that students may improve their comprehension of, and solutions to, future mathematical tasks. The study resulted in improvement in all four factors of observation, emulation, self-control and self-regulation thus providing evidence of a positive impact on student learning.The pilot involved a large first-year mathematics class who completed a formative piece of coursework prior to a problem class. At the problem class students were trained in the use of marking criteria before anonymously marking peer work. The pilot was evaluated using questionnaires (97 responses) at the beginning and end of the problem class. The questionnaires elicited students’ understanding of criteria before and after the task and students’ self-efficacy in relation to assessment self-control and self-regulation.The analysis of students’ descriptions of the criteria of assessment show that their understanding of the requirements for the task were expanded. After the class, explanation of the method and notation (consistent and correct) were much more present in students’ descriptions. Furthermore, 67 per cent of students stated they had specific ideas on how to improve their solutions to problems in the future. Students’ self-perceived abilities to self-assess and improve were positively impacted. The pilot gives strong evidence for the use of peer-assessment to develop students’ competencies as assessors, both in terms of their understanding of marking criteria and more broadly their ability to self-assess and regulate their learning.

2020 SPE President Shauna Noonan
Authors: Donnelly John
Published: September 2019

Interview with 2020 SPE President Shauna Noonan

Shauna Noonan will take office as 2020 SPE President during the SPE Annual Technical Conference and Exhibition 30 September–2 October in Calgary.

She is the director of artificial lift engineering for Occidental Petroleum Corporation, based in Houston, where she directs the company’s efforts in artificial lift system performance globally. Prior to joining Oxy in late 2015, she worked worldwide on artificial lift projects and technology development at ConocoPhillips and Chevron for more than 22 years. She has authored or coauthored more than 25 technical publications on the subject of artificial lift and is a frequent speaker at industry events.

She has been an avid SPE volunteer in many roles since first serving as a student section officer. She served on the SPE International Board of Directors as the Technical Director for Production and Operations from 2012–2015. She has driven the development of industry standards and recommended practices for artificial lift systems while serving as chair for ISO and API committees, and has received industry awards for her contributions to the discipline.

Noonan holds a BS degree in petroleum engineering from the University of Alberta.

What key issues will you emphasize during your year as president?

I want to focus on strengthening five areas for SPE to remain a trusted, unbiased source of technical information, be the membership of choice for professionals in oil and gas, and to be respected both within and outside of our industry. When people see that SPE logo, it should be synonymous with excellence in terms of all our offerings to our membership.

The theme of my presidency is “SPE strong,” strengthening the core of our society. The five areas are:

- Strengthening the technical quality of our publications, presentations, and events

- Strengthening the tools and methods by which we disseminate knowledge to our members

- Strengthening our core functions, with an additional focus on automation and digital science

- Strengthening knowledge transfer in unconventional resources

- Strengthening the feedstock of incoming talent into the industry.

How will you go about strengthening these areas?

For the past year in my role as incoming president, I have been working with my fellow board members and SPE staff to develop the various initiatives around my five focus areas. I will share those details in each of my monthly JPT columns along with updates on our progress.

In the latest SPE Strategic Plan, there is an emphasis on instilling professional pride.

What should be the focus?

I am proud to be a petroleum engineer but I, like many of our members, have not been adept at explaining what exactly our industry does. We need to learn how to have an effective conversation with those outside of our industry on how we lift the world out of poverty and improve the quality of life by providing affordable, sustainable energy while targeting carbon neutrality. An effective conversation is an open dialogue, not a PowerPoint presentation or a factual document.
Drilling Change Requires Changing Drillers
Authors: Rassenfoss Stephen
Published: September 2019

There is a lot of buzz about digital data and analytics changing drilling, and far less talk about teaching those who drill the wells how to deliver on that promise. That looks like a major oversight to Kevin Krausert, the chief executive officer of Beaver Drilling.

“Our industry is trying to figure out how we can engineer the humans out of this change. And we need to be thinking about how we put the humans in charge of engineering this change,” Krausert said.

His critique was delivered during a panel discussion at this year’s SPE/IADC Drilling Conference and Exhibition. The head of the small Canadian drilling company argued that the value of digital- and data-driven change will depend on whether workers skilled at running a mechanical system are prepared to lead teams finding way to use digital tools to drill more productively.

To try to back up that claim, Beaver created a 2-year program in partnership with the University of Calgary to create the Avatar program to prepare students ranging from roughnecks to drilling managers for digital change.

The notion that an employee for a drilling contractor who may never have gone to college is the point person for drilling innovation is counterintuitive. But experience with drilling improvement programs has found that the ones on the rigs play a critical role.

“The fundamental shift has to be in the•mindset of the guys who are right there in the thick of it. They are the ones affecting the change; they are the ones who can lead the movement,” said Jennifer Zieglgansberger, an executive coach in Calgary who partnered with Beaver to create Avatar.

People-Driven Change

Beaver’s story is one of four examples of worker-centered innovation efforts in the oil industry.

Occidental Petroleum has slashed drilling costs using a flood of data from wired drilling pipe. The key to doing so was the teamwork on that rig, and others nearby, to systematically improve performance (SPE 194093).

Advanced technology provided an unusually detailed picture for a crew “systematically engaging the rig in identifying opportunities for improvement and using engineering design to make continuous improvements that can be used anywhere,” said Molly Giltner, a senior drilling engineering supervisor at Occidental, who delivered a paper on the project at the drilling conference.

“People can do it, they just need the information,” said Giltner, the project leader. “They need to be told they can change things. Motivating people makes a huge difference. We do not talk about that a lot as engineers and they do not talk about that in school.”

Corva has grown rapidly due to the strong demand for its real-time data and analysis system. In a year, it has gone from a couple of rigs equipped with its drilling advisory system to 250 rigs and 35 clients by September, said Ryan Dawson, chief executive officer of Corva.
To “Right Size” Fractures, Producers Adopt Robust Monitoring and Custom Completions
Authors: Jacobs Trent
Published: September 2019

As the shale sector looks for ways to improve well results, momentum is building to take a much closer look at how and where hydraulic fractures are created while pressure pumping fluids into tight, complex reservoirs.

The effort is being driven by unresolved questions over optimal well spacing and fracturing techniques. They are two closely related issues that dovetail into sector-wide production shortfalls associated to frac hits, a common well-to-well effect that experts in the technical community have recently named fracture-driven interactions.

One of the biggest challenges in overcoming these issues is to learn how to control the size of hydraulic fractures (the general emphasis is on reducing their lateral and vertical extensions) with a far finer degree of accuracy and finesse than is realistic today. There is an expanding array of diagnostic studies and new technologies working to this end. Several of the latest examples were highlighted at the recent Unconventional Resources Technology Conference (URTeC) in Denver.

Operators both large and small used the conference as an opportunity to express support for the broader use of tools considered to be classic components of petroleum and reservoir engineering: wellhead and bottomhole pressure gauges. These two technological cousins are nothing new to the oil field, but have only recently become viewed as essential among those seeking affordable answers about how their fractures behave during the treatment.

“The industry badly needs a low-cost, stage-by-stage method that we can use for assessing the reservoir quality, the completion design, and fracture complexities,” said Michael Sullivan, a reservoir diagnostics advisor with Chevron, during a technical session at URTeC. “Unfortunately, the high-cost and operational complexity is a barrier to most other stage-level assessments. What we need is something we can afford to do.”

Sullivan was presenting a paper (URTeC 970) that describes how Chevron’s Canadian asset team in the Duvernay Shale recently began using “free” wellhead pressure data to estimate each fracturing stage’s performance. His hope is that others follow the workflows as Chevron looks at more than half-a-dozen ways to use the data (including perforation cluster efficiency analysis and frac hit identification) to refine its completions approach.

Sullivan highlighted that the new learnings are thanks to pressure gauges it uses per standard procedure, meaning they are on wellheads whether the data is analyzed or not. To drive down costs further, Sullivan advised other operators to buy their own gauges vs. renting them from service companies. “What I’ve been emphasizing around our company is that this is a measurement we can afford to make—so let’s make sure we’re getting the most out of it,” he•added.
Technology Focus: Field Development (September 2019)
Authors: Capello Maria A.
Published: September 2019

Technology Focus

Field developers are making bold step changes to form their optimization strategies on the crests of digital transformation, using massive data analytics, machine learning, cloud computing, and data-sharing strategies for oil and gas fields in all stages of development. This trend will only grow, following the imperative to ensure the sustainability of new assets and extend the life of brownfields of any size.•

Current trends in field development are to study, model, and understand the time-lapse effects in those fields where optimization of costs, environmental challenges, and sustainability are key differentiators. In onshore or offshore heavy-oil developments, as well as in shale oil and gas, massive data analytics and optimization techniques revolutionize work flows in field development with great force and speed. Digital oilfield frameworks, fast-track modeling, genetic algorithms, particle-swarm optimization, ensemble-based optimization, and closed-loop reservoir management are the leading best-decision loops.

Operating companies of all sizes and profiles—national oil companies, large international oil companies, and small private investments—are migrating from structured, linear, and conventional approaches in field development toward more-efficient and data-driven work flows, with activities executed in parallel to benefit all fronts, and fit-for-purpose and temporary working teams. The investments of time and effort are focused to better understand and predict how to reduce or avoid the interference among child and parent wells in shale oil or to ensure the sustainable production from offshore heavy-oil developments. Field development and field-operation optimization become joint efforts as the loops of production are shorter and the data are shared among several disciplines, interconnecting and integrating their goals.

The three selected papers provide an opportunity to catch up with the thrilling step-change evolution in field development. The industry continues its digital transformation, and field development is leading the•wave.

Published: September 2019

Background: The aim of this study was to evaluate the association between magnitude of T-SPOT.TB and clinical characteristics in active pulmonary tuberculosis.
Methods: In this retrospective multicenter investigation, the medical records’ archives of PTB patients were reviewed. Data including gender, age group, bacterial culture, sputum-smear microscopy, lung cavity and range of PTB were extracted from the records. The Jonckheere-Terpstra test and chi-square test for trend were used to evaluate the association between magnitude of T-SPOT.TB and clinical characteristics in active pulmonary tuberculosis.
Results: A total of 1252 PTB patients were included in this study.Chi-square trend tests revealed significant positive trends between bacterial culture and magnitude of T-SPOT.TB A (χ2 =18.978, P <0.001) or T-SPOT.TB B (χ2 =19.677, P <0.001). There were significant positive trends between AFB and magnitude of T-SPOT.TB A (TJT =345784, P <0.001) or T-SPOT.TB B (TJT =336017, P <0.001). There was a significant positive trend between range of lung cavity and magnitude of T-SPOT.TB A (TJT =326079.5, P =0.023). There were significant negative trends between age group and magnitude of T-SPOT.TB A (TJT =204306, P <0.001) or T-SPOT.TB B (TJT =206572, P <0.001).
Conclusions: The magnitude of T-SPOT.TB in PTB patients may reflect the condition of the patients and could be helpful for clinicians to assess the degree of infection and lung tissue damage.
Only extremely high peak serum estradiol adversely affects endometrial receptivity in IVF treatment

Published: September 2019

Purpose To explore the effect of different concentrations of peak serum estradiol levels on endometrial receptivity quantitatively.
Methods In our reproductive medicine center, two best quality of day 3 (D3) embryos were transferred or frozen according to E 2 and progesterone levels on the day of human chorionic gonadotropin (hCG) administration and the number of oocytes retrieved. The remaining embryos were cultured to blastocyst stage and frozen. The patients were then categorized into three groups. The patients with frozen-thawed D3 embryo transfer in artificial cycles without blastocyst frozen served as group 1, those with fresh D3 embryo transfer without blastocyst frozen as group 2, and those with fresh D3 embryo transfer with blastocyst frozen as group 3. Each group was further stratified into 4 sub-groups according to E 2 levels on the day of hCG administration. Clinical pregnancy rate, implantation rate and abortion rate of frozen-thawed and fresh D3 embryo transfer were compared among the three groups in the same stratified E 2 levels.
Results For E 2 <7,000 pg/mL, group 1 and group 2 had similar clinical pregnancy rate and implantation rate. But for E 2 ≥7,000 pg/mL, the clinical pregnancy rate in group 1 was significantly higher than in group 2 (p<0.05). For E 2 <7,000 pg/mL, pregnancy rate and implantation rate in group 1 were significantly lower than those in group 3 (P<0.05). But for E 2 ≥7,000 pg/mL, the pregnancy rate in group 1 was significantly higher than in group 3 (P<0.05). There was no significant difference in the abortion rate between group 1 and group 2, or between group 1 and group 3.
Conclusions High serum E 2 concentration does not impair implantation and pregnancy rates unless exceeding a certain limit (e.g. 7,000 pg/mL) on the day of hCG administration. Since peak E 2 level was related to OHSS and adverse pregnancy outcomes, further study is needed to set a threshold peak E 2 level for fresh embryo transfer.

Comparison of household expenditure between urban slum and non-slum dwellers in a Southwestern metropolis, Nigeria
Authors: Obembe Taiwo A , Levin Jonathan , Fonn Sharon
Published: September 2019

[EXSCINDED] Abstract Background The growth of urban slums has become a source of global concern due to the less-than-optimal conditions in which they exist. Of particular interest here, are the spending patterns of slum inhabitants in order to understand where funds are diverted from when a sudden health challenge occurs. This study sought to provide baseline statistics of household expenditure patterns of selected slums dwellers in southwestern Nigeria using non-slums dwellers as a comparison group.Methods The study utilised a retrospective descriptive cross-sectional design involving 450 respondents from both slums and non-slums. Information pertaining to spending patterns was collected using semi-structured questionnaires (adapted from the World Health Survey) and cost diaries. Results are presented as weighted means and weighted percentages.Results A total of 239 participants were slum dwellers while 211 were non-slum dwellers. Mean age of slum dwellers was 38years (95% CI: 35 – 42 years) while non-slum dwellers had a mean age of 39 years (95% CI: 36 - 41). Mean monthly income for slum dwellers was N93,118; 95%CI: N66,106 – N120,130 while that of non-slum dwellers was N269,700; 95%CI: N209,312 – N330,227. Mean monthly expenditure of N 21,335 was spent on food among the slum dwellers and N 25,131 among the non-slum dwellers. Both slum dwellers and non-slum dwellers spent a large proportion of their monthly income on food, rent, education and health care.Conclusion The earning capacity (income) of respondents from the slums is low compared to the non-slum counterparts. Money allocated to specific and basic household items account for major portions of the slum dwellers’ income, thus they are less likely to be prepared to deal with costs of a medical emergency (compared to non-slum dwellers). Concerted efforts are needed to provide more jobs or empowerment schemes that can alleviate the burden of poverty in the slums and improve their living conditions also.
The Association Between the Severity of the Mandibular Inferior Cortex Porosity and the Number of Remaining Teeth in Elderly Indonesian People
Authors: Kiswanjaya Bramma , Bachtiar-Iskandar Hanna H
Published: September 2019

Background The purpose of this study was to investigate the association between the severity of the mandibular inferior cortex (MIC) porosity and the number of remaining teeth in elderly Indonesian people.Materials and methods This cross-sectional study was conducted by measuring secondary data on panoramic digital examinations of patients aged 50 years and older. A total of 428 panoramic radiographs were measured from January 2017 to December 2018. The number of remaining teeth (including the third molars) was evaluated. Mandibular porosity was measured by using panoramic radiographs, according to the MIC classification: normal; mildly to moderately eroded; and severely eroded cortex.Statistical analysis used Data analysis was done using Mann-Whitney nonparametric tests to verify the relationship between the MIC classification and the number of remaining teeth. Multiple linear regression analysis was performed to investigate the relationship between confounding variables.Results A significant correlation was found between MIC classification and the number of remaining teeth on the Mann-Whitney test (P < 0.001). Multiple linear regression analysis showed that MIC classification was significantly associated with the value of the number of remaining teeth after controlling for gender and age (β = -0.37, R2 = 0.22, P < 0.001). Subjects with MIC class 3 were 7.14 times more likely to lose their teeth than subjects with MIC class 1 or class 2.Conclusions Our study demonstrated that there was an association between the severity of mandibular inferior cortex porosity and the number of remaining teeth in elderly Indonesian people.
Proteins encoded by Novel ORFs have increased disorder but can be biochemically regulated and harbour pathogenic mutations
Authors: Jagannathan N. Suhas , Meena Narendra , Bhayankaram Kethaki Prathivadi , Prabakaran Sudhakaran
Published: September 2019

Recent advances in proteogenomics indicate that protein or protein-like products can be encoded by previously uncharacterized Open Reading Frames (ORFs) that we define as Novel Open Reading Frames (nORFs)1​ ​,2​ ​. Although it is yet unclear if these protein or protein-like products could possess any significant biological function hopes have been raised to target them for anticancer and antimicrobial therapy 3​ ,4​. In this study, we used computational tools to systematically investigate these novel protein sequences for their propensities toward structural disorder, post-translational modifications (PTM) and mutational densities. We found that these novel proteins have significantly higher disorder and similar PTM frequencies compared to known proteins. Although these regions were found to harbour deleterious mutations, we did not observe any correlation between the pathogenicity of mutations and their location (ordered/disordered) within these novel proteins. This study suggests that these nORFs encode an important class of proteins, that could undergo sequence, structural or regulatory changes during complex diseases, and hence warrant further study.
Safe Learning Environment Perception Scale (SLEPS): A Validity and Reliability Study
Authors: HAİDARİ Sayed Masood , KARAKUŞ Fazilet
Published: September 2019

The purpose of this study was to develop and
cross-validate a measurement scale on students’ perception of a psychologically
safe learning environment in the Turkish context. Primarily, the scale items
underwent two rounds of expert review. Then, a series of item elimination or
revisions were performed to improve their relevance to the content domain and
their comprehensibility for the target group according to the CVI and modified
kappa statistics. The results yielded a strong content validity and clarity of
the items. Then, the exploratory factor analysis and parallel analysis were
performed based on the data from 556 secondary school students (grade 5-8),
which suggested a three-factor solution. The KMO was 0.942 > 0.50 with
significant Bartlett test values, x2(496) = 8295.592, p < 0.001 and the explained
total variance was 50.622 %. Each item had a factor loading of > 0.58
with > 0.40 common correlations. To validate this structure, confirmatory
factor analysis was conducted based on the data from a different group of
students (N = 339). The goodness of fit indices, factor loadings, and
the t statistics supported a good-fitting measurement model, x2(N = 339) = 925.29, df
= 461, p < 0.001; x2/df
= 2, NFI = 0.94, NNFI = 0.97, CFI
= 0.97, SRMR = 0.069, RMSEA = 0.055. The convergent and discriminant validity
were also supported. In general, the SLEPS has potential applicability both at
the lower and upper secondary schools (public and private) and at the
educational centers for the gifted.
Anomalous dimensions of potential top-partners
Authors: Buarque Franzosi Diogo , Ferretti Gabriele
Published: September 2019

We discuss anomalous dimensions of top-partner candidates in theories
of Partial Compositeness. First, we revisit, confirm and extend the
computation by DeGrand and Shamir of anomalous dimensions of fermionic
trilinears. We present general results applicable to all matter
representations and to composite operators of any allowed spin. We then
ask the question of whether it is reasonable to expect some models to
have composite operators of sufficiently large anomalous dimension to
serve as top-partners. While this question can be answered conclusively
only by lattice gauge theory, within perturbation theory we find that
such values could well occur for some specific models. In the Appendix
we collect a number of practical group theory results for fourth-order
invariants of general interest in gauge theories with many irreducible
representations of fermions.

Existe espaço ideal para a gestão de águas? Esta indagação consiste no ponto de partida para a discussão sobre a noção de território-sistema. Para discutir esta noção partiu-se da crise de abastecimento de água ocorrida em 2014-2015 que ganhou visibilidade e assumiu projeção como crise do Sudeste e, em alguns momentos, como crise do país. Questões como segurança hídrica, desajustes entre investimentos em infraestrutura e crescimento da demanda, intensidade da urbanização e estiagem prolongada resumem argumentos e justificativas que foram mobilizados para explicar e subsidiar estratégias de saída da crise e a tomada de decisão para resolver o problema. Argumenta-se que a crise expôs inadequações entre organização institucional e determinada concepção de gestão do território e dos recursos em duas escalas: a escala metropolitana e a escala da bacia do Paraíba do Sul. De um lado, a expansão de cidades e a formação de aglomerados metropolitanos, de outro, unidades de gestão de recursos hídricos e sistemas técnicos produtores de água indicam manifestações de rivalidades sobre recursos compartilhados e sobre o controle dos fluxos de água. Consideramos, pois, que esta crise não é exclusiva da estiagem em momento precisamente determinado, mas que tem origem nas condições de produção da água em quantidade e qualidade. A análise em duas escalas permite considerar a malha hídrica como objeto geográfico, substrato da articulação sincrônica de lugares e, contraditoriamente, vetor de rupturas. A fim de compreender essas inter-relações introduzimos a noção de território-sistema.
O capital imobiliário e o seu papel no processo de formação de novas centralidades e de verticalização na Região Metropolitana de Florianópolis/SC
Authors: Vera Margaux Hildebrandt , Silveira Márcio Rogério
Published: September 2019

O processo de verticalização está vinculado ao desenvolvimento capitalista do setor financeiro-imobiliário, no qual agem as forças de reprodução do capital por meio da construção civil. Diante disso, o objetivo deste artigo é demonstrar que os setores com processos de verticalização na área conurbada da Região Metropolitana de Florianópolis (RMF) foram impulsionados pelos poderes públicos municipais para o benefício de determinados grupos econômicos e retratar o desenvolvimento da cidade. Tais setores consolidaram as centralidades e contribuem para o adensamento dos fluxos de circulação, sem prever as repercussões que causariam para o espaço. Nessa perspectiva, analisaremos as novas áreas com processos de verticalização, a fim de desvendar as atuais dinâmicas da indústria da construção civil sobre o espaço urbano.
Estatísticas e Políticas Públicas orientadas por evidências no Brasil: o caso das Políticas de Desenvolvimento Social nos anos 2000
Authors: Jannuzzi Paulo de Martino
Published: September 2019

A tese central deste texto é mostrar como a produção regular e a ampla disponibilidade de Estatísticas Públicas, em particular, dos Indicadores Sociais construídos a partir da Pesquisa Nacional por Amostra de Domicílios (PNAD), cumpriram papeis importantes na agenda de combate à fome e na Política de Desenvolvimento Social no país, ao aportar insumos para  defesa da sua relevância, desenho, monitoramento e avaliação dos seus programas. Inicia-se com uma recensão sobre o surgimento dos Indicadores Sociais em meio à estruturação do Estado de Bem-Estar ao longo do século XX. Em seguida, apresenta-se como a PNAD foi se transformando em uma pesquisa com escopo temático cada vez mais amplo e aderente às preocupações do Estado e Sociedade brasileiros, e como as informações levantadas na pesquisa foram sendo empregadas na Política de Desenvolvimento Social e seus programas no país. À guisa de conclusão, advoga-se pela necessidade de uso mais bem informado e plural das estatísticas pela mídia brasileira, pelos riscos de crescente deslegitimação de políticas e programas constituintes da trilha civilizatória inscrita na Constituição Federal de 1988.

Authors: Barrozo Ligia Vizeu , Cabral-Miranda William , Galvão Natalia Bianchi
Published: September 2019

O objetivo do presente trabalho foi ilustrar como a segregação residencial urbana pode ser avaliada e monitorada a partir de dados do questionário da amostra por área de ponderação dos Censos Demográficos do Instituto Brasileiro de Geografia e Estatística (IBGE) de 2000 e 2010. Entre os dois Censos, embora na média do município a segregação não tenha tido aumento muito importante, localmente as variações foram relevantes, provavelmente associadas à valorização do uso do solo urbano neste período. Os índices utilizados mostram potencial como instrumentos para avaliação da segregação em seus diversos aspectos para subsidiar medidas de redução ou mitigação de suas externalidades.
Contribuições do Instituto Brasileiro de Geografia e Estatística para análises intraurbanas: a organização social no território a partir de Categorias Sócio-ocupacionais
Authors: Miranda Lívia
Published: September 2019

O objetivo do artigo é discutir o padrão de organização social do território, a partir da localização dos grupos ocupados para analisar as alterações na estrutura social metropolitana, tomando como caso a Região Metropolitana do Recife (RM Recife). Os estudos “Tipologia Intraurbana: espaços de diferenciação socioeconômica em concentrações urbanas no Brasil” (IBGE, 2017c) e “Região Metropolitana do Recife: Estratificação social, estrutura e organização do território” (MIRANDA; BITOUN, 2015) foram as bases para a discussão proposta nesse artigo. Ao analisar os tipos sócio-ocupacionais, foi possível verificar os efeitos da transição demográfica; o aprofundamento das desigualdades territoriais nas áreas centrais; a reconfiguração das centralidades, motivada pela implantação de grandes empreendimentos em espaços periféricos. Esses resultados, no entanto, não mostraram grandes mudanças na estrutura social da Região Metropolitana. A análise realizada e a relevância de seus resultados para a compreensão da diferenciação socioespacial demonstram a extrema importância da informação produzida e acessível pelo IBGE, uma vez que os dados censitários oferecem infinitas possibilidades de sistematização que ajudam a revelar a dinâmica da organização territorial.

The analysis allowed the authors to describe a number of universal ideological characteristics inherent in the ideology of fascism as a whole, regardless of the country of manifestation. These characteristics include extreme nationalism, chauvinism, xenophobia, racism, and the myth of the revival of the nation from cultural decline. The authors revealed the evolution of the basic ideological characteristics of fascism: they distance themselves from the classical ideology and practice of fascism and adapt to the modern historical period. The paper contains an analysis of the political programs of right-wing parties in some European countries, which makes it possible to classify these parties as neo-fascism, based on the identified continuity of the ideological characteristics of fascism. Based on an analysis of the electoral results, the authors state the fact of a threat emanating from the ideology of fascism for modern political processes.

Published: September 2019

The paper features the problems of staff motivation in the automotive industry in the context of foreign economic activity. In the modern conditions, the increase in the efficiency of foreign economic activity of automobile industry enterprises is largely ensured by the development of human capital and the motivation system that is able to maximize the potential of employees. The research objective was to develop an innovative approach to the staff motivation in the automotive industry in the context of foreign economic activity. The paper contains a retrospective analysis of various approaches to employee motivation. Comparative and benchmarking approaches were used to substantiate the most promising and modern ways of stimulating the labor activity of personnel. Modern technologies of motivation have a wide range of negative consequences for the automotive industry. For instance, the imbalance in personnel training results from the fact that there are not enough qualified technical and computer specialists. Moreover, staff motivation methods have been limited to monetary incentives, which has led to low commitment, involvement, and loyalty. There is also a lack of mechanisms for innovations. These processes reduce the economic sustainability of automotive enterprises, as well as their ability to expand markets and competitiveness in the global economy. A system of integrated analysis of approaches could solve the problems of staff motivation in the automotive industry enterprises of the Russian Federation in the modern foreign market conditions.
