Published: May 2017

Despite of women advancement in politics, business, and other spheres of life, women are largely absent from senior position and are marginalized in terms of power and resources. In Latvia women set up and lead vibrant and successful governmental and private organizations. The purpose of the article is to explore cultural roots of gendered inequality in leadership and economic power positions by the literature review and as reviled in interviews.  Interview data reveal the obstacles women need to overcome in their career advancement and their stories of success. Methodology: The study presents a qualitative study on women’s leadership as defined in legislation and recent research and is supported by the qualitative inquiry of life stories of seven women engaged in the education’s management programs. These women undertake leadership positions in their organizations. Conclusions: To conclude, the goal of equal participation for both male and female players in all significant spheres of life as declared in the international legislation and the United Nations, declarations will strengthen democracy and will promote its proper functioning. The authors assert that higher education through management study programs can also build women’s capacity for leadership by assertiveness training and encouraging independent and critical thinkers.

Authors: Nagle Erika , Strode Aija
Published: May 2017

Student achievement depends very much on reliable and valid assessment methods. In this paper assessment of reflecting writing and computer based on - line tests will be discussed. The main challenge in evaluation reflecting writing tests is objectivity. For this purpose test papers were evaluated mutually by different lecturers and grading compared by Pearson`s correlation coefficient. Results showed that strong correlation exists in all compared assessor pairs. In computer based on-line test in Moodle platform evaluation is done by computer programme and grading is announced just after student finishes the test. In purpose to maintain student`s reflective skills clinical case and/or problem were included in computer based tests. These questions were evaluated manually. Two types of assessment – manual and computer based have their advantages and disadvantages. Our conclusion is that different tests and assessment methods should be used for comprehensive and objective evaluation of student`s outcomes.

Altmetrics: Six Years of Changing Scholarly Appraisal
Authors: Samanta Dyuti , Dutta Bidyarthi
Published: May 2017

The last decade of the 20th century was marked as the opening gateway to internet and communication revolution, which added new dimensions to information and knowledge society.  The scholarly community of today’s knowledge society communicates between each other in a non-traditional way besides the traditional way. The arrival of web 2.0 and scientists’ gradual use of said platforms as tools for the diffusion and receipt of scientific information and with part of the scientific community relatively receptive, that scientometrics 2.0 began to be discussed.  Another milestone in the era of scientometrics 2.0 is the ‘Wikimetrics’. After the ‘Wikimetrics’ next footprint comes with the advent of ‘Article-level metrics’. Article-level metrics followed by Altmetrics, i.e. Alternative Metrics. The term altmetrics was coined by Jason Priem in 2010, as a generalization of article level metrics, and rooted in the twitter #altmetrics hashtag. Although altmetrics usually functions as metrics about articles, but it can also be applied to people, journals, books, data sets, presentations, videos, source code repositories, web pages, etc. Altmetrics does not cover just citation counts, but also other aspects of the impact of a work, such as how many data and knowledge bases refer to it, article views, download, or mentions in social media and news media. In this paper, the altmetric scores of top-cited altmetric papers are presented. Also, the contents of the same are analysed and presented. It is interesting to note that all top-cited papers appeared from diverse subject domains, i.e. big data in science, biological science, medical science, research methodology, social studies, citation studies and scientometrics, different issues involved in social networking et al. The subject domain altmetrics is a highly interdisciplinary field covering all major areas of universe of knowledge. This study reflects other notable feature, i.e. the discord between traditional metric (times cited) and modern metric (altmetric score).
Information Access to Villagers through Connecting Different Sectors: Infonetwork Centre Model
Authors: Kumar Naresh
Published: May 2017

Everyone needs information and to be able to access information is a fundamental right. Most Indian villages are not well connected; so villagers are deprived of access to information. The main objective of this paper is to suggest a model infoNetwork centre as a mechanism for connecting the different information providing agencies (health, education, banking, government, employment agencies, agriculture sector, religion, non-governmental organisations, etc.) of society to villagers. In India both government and private organisations operate in many sectors like health, education, and employment. Observation and interview methods are used to understand villager's information needs and suggest a model of "infoNetwork centre" for villages.
La prohibición de reforma peyorativa como principio y garantia constitucional
Authors: Echeverry Enciso Yecid , Oñate Delgado Laura Valentina
Published: May 2017

La non reformatio in peius es un principio constitucional y una garantía procesal que limita la capacidad decisoria del juez superior, prohibiendo agravar la situación del procesado que ha apelado la sentencia o parte de ella como apelante único. La excepción a la aplicación de dicho principio se halla en las decisiones que por ley deben ser sometidas a consulta. En torno a dicho principio se ha consolidado amplia jurisprudencia de la Corte Constitucional como de la Corte Suprema de Justicia, las cuales han definido su alcance y aplicación contrastando el citado principio con el de legalidad, el debido proceso y el derecho de defensa.
Contact with poultry and animals increases risk of Campylobacter infections in adults of Ardabil province, Iran
Authors: Ranjbar Reza , Babazadeh Daryoush
Published: May 2017

Background
The acute gastroenteritis caused by campylobacteriosis is known as one of the common infectious diseases with worldwide distribution. The aim of this study was to detect Campylobacter species in stool samples by routine culturing and polymerase chain reaction (PCR) and explore the risk factors in adult subjects in East Azerbaijan province of Iran.

Methods
A cross sectional study involving 1010 adult subjects, from whom stool samples were collected. Samples with inflammatory criteria like fecal leukocytes (WBC ³5) were selected and isolated through fecal lactoferrin detection test. The WBC ³5 and lactoferrin positive samples were selected for Campylobacter detection by culture and PCR methods. The required information consisting of gender, age, place of habitation, and contact with poultry and animals were asked and recorded. Chi-square test and prevalence ratio (PR) was used to analyze the data.

Results
Of 1010 stool samples, 231 (22.9 %) had WBC ³5, and from these samples 58 (25.1%) were positive by culturing and 61 (26.4 %) by PCR. Subjects having habitual contact with animals and poultry had increased risk of Campylobacter infections by 1.65 times compared with subjects without contact with animals and poultry (PR=1.65; 95% CI:1.07-2.68).

Conclusions
Detection of Campylobacter infections by PCR was more sensitive in adults. Investigation of Campylobacter prevalence in Ardabil showed this bacterium should be viewed as one of the possible pathogens in inflammatory diarrheal cases. People having habitual contact with animals should check the health of the animals regularly and not consume food from suspected sources.

Authors: Pinzon Rizaldy Taslim , Babang Fransiska Theresia Meivy , Pramudita Esdras Ardi
Published: May 2017

Background
The mortality rate after ischemic stoke is influenced by various factors. Prognosis after ischemic stroke can be predicted using a scoring system to help the doctor to evaluate patient’s condition, neurologic deficits, and possible prognosis as well as make appropriate management decisions. The objective of this study was to identify the factors which determine mortality rates in patients after ischemic stroke and to determine the prognosis of ischemic stroke patients using the predictive mortality score.

Methods
This was a nested case control study using data from the stroke registry and medical records of patients at the Neurology Clinic of Bethesda Hospital Yogyakarta between 2011-2015. Data was analysed using simple and multiple logistic regression analysis. The scoring was analyzed using receiver-operating characteristic (ROC) curve and the cut-off point using area under the curve (AUC).

Results
Multiple logistic regression analysis showed a significant association between mortality of ischemic stroke patients and age (OR: 4.539, 95% CI: 1.974-10.439, p<0.001), random blood glucose (OR: 2.692, 95% CI: 1.580-4.588, p<0.001), non-dyslipidemia (OR: 2.313, 95% CI: 1.395-3.833, p=0.001), complications (OR: 1.609, 95% CI: 1.019-2.540, p=0.041), risk of metabolic encephalopathy (OR: 2.499, 95% CI: 1.244-5.021, p=0.010) and use of ventilators (OR: 17.278, 95% CI: 2.015-148.195, p=0.009).

Conclusions
Age, high random blood glucose level, complications, metabolic encephalopathy risk and the use of ventilators are associated with mortality after ischemic stroke. The predictive mortality score can be used to assess the prognosis of patients with ischemic stroke.

Published: May 2017

INTRODUCTION - Lymphadenitis is the most common extrapulmonary manifestation of tuberculosis. It is important for otolaryngologists to be aware of TB in head and neck region and its various manifestations. Lymphadenopathy can progress to abscess and fistula formation, which can be disabling and socially unacceptable. ATT under dots is the main treatment while surgery is required for enlarged lymph nodes or tuberculous lymph node which does not regress with medication. OBJECTIVE - This study aims to find the role of surgical excision of lymph nodes in treatment of tuberculosis of neck lymph node. MATERIALS AND METHODS - Total 91 patients were diagnosed first time with tuberculosis of neck lymph node. All patients were started on anti tubercular treatment. Those patients who had been cured after completion of ATT cat-I, were followed up for 1 year. Surgical intervention (adjuvant to ATT cat-II ) was done in patients who were not cured after ATT cat-1, or had relapse in 1 year follow up. RESULTS - Surgical interventions were done in total 37 patients (25 treatment failure patients and 12 relapse patients). and all patients who got surgical interventions had no relapse or treatment failure during follow up. CONCLUSION-In patients who are not cured with ATT alone, early surgical intervention reduce complications such as abscess, sinus, fistula formation, or spread of disease to other parts of body. Timely surgical intervention also reduce the morbidity and increase the quality of life of patients.

Authors: Inklebarger James , Galanis N  , Kumar D  , Krishaswa K  , Leddy J
Published: May 2017

Objectives: Though identification of underlying anatomical causation and surgical management of is the mainstay of treatment, needle aspiration with or without injection of corticosteroid is a common conservative management for enlarged and painful Baker's cysts (BC). This report explores some of the circumstances in which ultra-sound guided BC aspiration may be a first-line option. Methods: A 46 year-old recreational athlete developed marked posterior knee pain and swelling several years after arthroscopic medial meniscal debridement. Needle aspiration of a large & symptomatic BC was performed under ultrasound guidance, and the patient commenced rehabilitation. Results: Posterior knee pain completely abated post procedure. Increased knee joint flexion, and squatting was sustained, without cyst recurrence on 6 month follow-up. Conclusion: Ultrasound-guided aspiration of painful or enlarged Bakers cyst may have sustained benefits after knee arthroscopy in the older athlete, particularly in cases when no further surgery is indicated or planned. Diagnostic ultrasound differentiates BC from other types of masses, provides real-time dynamic visualization of the popliteal neurovascular bundle, guides needle placement, and helps to insure complete BC aspiration, accurate injection, and fenustration. BC aspiration, may also be indicated in cases of operative delay, comorbidities contraindicating surgery, to facilitate rehabilitation, or when the underlying causation of BC is indeterminate. Large cysts causing neurovascular compression may require more emergent aspiration. As this case report illustrates, symptomatic relief and functional improvements may be sustained for several months.

Hydatidosis is a parasitic disease considered benign but can become dangerous because of its complications. It is a real public health problem in the world by its frequency, morbidity, and its potential mortality. This work is a retrospective study, which was carried out on 15 patients with hydatid cyst of the liver complicated, admitted between 2012 and 2015 at the department of general surgery of the military Hospital Avicenne. The aim of this study is to report the epidemiological, diagnostic features and therapeutic management. The results of the epidemiological study showed that the hydatid cyst of the liver affects young adults with an average age of 38,5 years and a clear male predominance. The complicated form represents 15% of cases. The clinical expression was dominated by the right upper quadrant pain (80%) and fever (70 %). The most common complication was represented by fistula in the bile ducts found in 60% of cases. Ultrasound is the main paraclinical examination that allows the diagnosis. Cysts were type III in 70 % of cases, localized in the right lobe in 80 % of cases. Surgical treatment is performed in all cases. Medical therapy was used in 2 cases in association with surgery. Laparotomy was performed for all patients. Conservative procedure, which is the resection of the bulging dome, was used in all cases excepted for one patient who had a liver hydatid cyst in central location, who was treated by a trans-fistulo-oddian internal drainage. The average length of hospitalization was 17 days. Our results were satisfying with weak rate of morbidity (30%) and no recurrence. Prophylaxis is the best treatment in endemic areas.

This application is based on a MSOGI-FLL (Multiple Second Order Generalized Integrators - Frequency Locked Loop) method, which is composed of multiple double adaptive filters called "Dual Second Order Generalized Integrators" (DSOGI) coupled to the frequency detector entitled "Frequency Locked Loop" (FLL) which keeps the set synchronized, even in abnormal situations.
Inversor Multinível Assimétrico Bidirecional Com 49 Níveis Na Tensão De Saída Usando Apenas Uma Fonte CC E Com Poucas Chaves Em Condução
Authors: Jó de Mesquita Samuel , Luiz Marcelo Antunes Fernando , Daher Sérgio
Published: May 2017

Esse artigo propõe um inversor multinível assimétrico bidirecional empregando apenas uma fonte CC. A topologia proposta é baseada no uso de células H-bridge (HB) associadas com duas chaves bidirecionais (2cb) resultando na nova célula base referida como CHB-2cb. A associação em cascata de duas células CHB-2cb com apropriadas fontes de entrada pode gerar até 49 níveis na tensão de saída. Essa topologia usa somente uma ponte HB entre a fonte CC e um transformador de múltiplos secundários em média frequência para produzir as fontes de tensão assimétricas das células CHB-2cb em cascata que operam no estágio CA-CA. Esta proposição promove a redução do número de fontes de tensão isoladas dos inversores cascateados, e elimina a necessidade de um conversor CC-CC elevador de alto ganho, como no caso deste experimento que usa uma tensão de entrada CC de 48 V e uma tensão de saída CA eficaz de 220 V em 60 Hz. Essa proposta aumenta a eficiência do conversor, mantendo baixa distorção harmônica na tensão de saída e reduz o número total de componentes em condução quando comparada com conversor multinível convencional usando estágio CA-CA para produzir o mesmo número de níveis na tensão de saída. Análises teóricas e resultados experimentais são apresentados para validar o conversor proposto.

Published: May 2017

Este artigo apresenta uma nova estratégia de controle preditivo contínuo aplicado à malha de corrente elétrica do rotor de um sistema de geração eólico baseado no gerador de indução duplamente alimentado. O projeto do controlador é realizado a partir do modelo matemático da malha de corrente do rotor e sua sintonia é efetuada de forma simplificada através de dois parâmetros de ajuste, um para obter uma resposta rápida no seguimento de referência e o outro para reduzir as oscilações no sinal de controle. Desta forma, diminuindo oscilações no conjugado eletromagnético e nas potências instantâneas produzidas pelo sistema. Além disso, propõe-se a inclusão do modelo da saturação no controlador para evitar problemas de windup. Resultados experimentais são obtidos utilizando um protótipo de 3,7 kW que mostram a eficácia do controlador desenvolvido quando o sistema é submetido a variações de potência, velocidade do rotor e afundamento de tensão simétrico.
Controlador Robusto MPC-LMI Aplicado Ao Conversor Boost Com Célula De Comutação De Três Estados
Authors: Vinicius Silvério Costa Marcus , Everton Uchôa Reis Francisco , Carlos Teles Campos José , Gonzalez Nogueira Fabricio , Da Mota Almeida Otacilio
Published: May 2017

Este artigo propõe uma estratégia de controle preditivo baseado em modelo aplicado a um conversor boost com célula de comutação de 3 estados que confere mais simplicidade e sistematização nas fases de projeto e análise do controlador, cujo ganho integral ajustável dispensa o reprojeto nas matrizes de ponderação. Para simplificar a análise de estabilidade do controlador, utiliza-se o conceito de elipsoides de estabilidade, um assunto ainda pouco explorado neste contexto. O controle preditivo proposto parte da modelagem da planta no espaço de estados médio linear e variante no tempo, cujas variações paramétricas são tratadas como incertezas politópicas expressas por meio de desigualdades matriciais lineares (LMIs) com relaxações. Aspectos teórico-experimentais são aplicados e analisados em um conversor de 1 kW com incertezas na tensão de entrada e na carga. Além disso, para estabelecer uma base de desempenho, o MPC proposto é comparado com o controlador LQR clássico conhecido na literatura. A estratégia de controle proposta apresenta vantagens considerando as variações do modelo decorrente dos testes de cargas em aplicações de conversores estáticos CC-CC.

Published: May 2017

Objetivou-se conhecer a percepção dos enfermeiros da atenção básica sobre a assistência do paciente em hemodiálise. Estudo qualitativo, realizado com enfermeiros das unidades básicas de saúde de um município situado no centro oeste do estado do Paraná, por meio de entrevista. Para análise dos dados utilizou-se a temática de Minayo. Participaram da pesquisa oito enfermeiros, sendo todos do sexo feminino, com faixa etária entre 27 e 52 anos. Os discursos dos profissionais retrataram o desconhecimento de usuários dependentes de hemodiálise na área de abrangência da unidade de saúde e sobre a temática de aprimoramento e capacitações realizadas, nenhum profissional entrevistado relatou treinamento específico para assistência direcionada ao paciente em tratamento de hemodiálise. Com a análise das experiências e práticas vivenciadas foi possível constatar a imensa dificuldade dos profissionais em exercer a prática assistencial a pacientes/ usuários historicamente caracterizados pelo setor terciário. Com a falta de contato frequente do cuidado especializado pode-se perceber que a assistência do profissional enfermeiro só se realiza quando há procura pelo usuário na própria unidade de saúde.Palavras-chaves: cuidados de enfermagem; atenção primária à saúde; hemodiálise.
Some insights into an integrative mathematical model: a prototype-model for bodyweight and energy homeostasis
Authors: Pires Jorge Guerra
Published: May 2017

The ambition of this document is to set in evidence the prerequisite for integrative (mathematical) models, mechanism-based models, for appetite/bodyweight control. For achieving this goal, it is provided a scrutinized literature review and it is organized them in such a way to make the point. The quantitative methods exploited by the authors are called differential equations solved numerically; they are discussed briefly since it is not our goal herein to handle details. On the current state of the art, there is no mathematical model to the best of the author’s knowledge targeting at integrating several hormones at once in mathematical descriptions: even for single hormones, the literature is either occasional or do not exist at all; it is depicted some results for simple models already built. As it can be seen, the functions and roles seem fuzzy, most hormones seem to be piloting the same undertaking. The key challenge from a mathematical modeling perspective is how to separate properly the mechanisms of each hormone. The kind of pursuit presented herein could initiate an imperative cascade of mathematical modeling applied to metabolism of bodyweight control and energy homeostasis.

E como elementos limitantes foram identificados a pouca disponibilidade de carros, a desmotivação dos profissionais das equipes de atenção básica e o pouco tempo disponível para preparação das equipes para receber a AE/PMAQ.Palavras-chave: Atenção primária à saúde; avaliação de serviços de saúde; gestão de qualidade.
Gestão acadêmica exercida por professores universitários: um estudo de caso
Authors: Coelho Camila Henriques
Published: May 2017

No Brasil é muito comum que o professor universitário seja designado ao exercício de cargos administrativos sem que ele tenha sido previamente treinado ou orientado em relação às funções administrativas. Especificamente na área da saúde, não existem trabalhos que relatem ou questionem este processo de transição de professor de área técnica para gestor. O presente artigo trata-se de uma análise qualitativa sobre a perspectiva que professores com formação acadêmica em área da saúde ou biológicas possuem sobre o fato de assumirem cargo de gerência em uma universidade federal no estado de Minas Gerais. Com o objetivo de fazer uma reflexão sobre a importância de um treinamento prévio a estes gestores, o trabalho consiste numa descrição qualitativa dos principais questionamentos desses docentes durante a condução das atividades relativas ao trabalho de coordenação de colegiado de graduação ou pós graduação. Após comparação dos resultados das entrevistas com outros trabalhos da literatura com propósitos semelhantes, foi possível evidenciar que os professores acreditam não possuir formação qualificada e específica para assumirem cargos de gerência dentro da universidade e que seu trabalho, quando bem-sucedido, decorre de práticas empíricas
Zastosowanie modeli panelowych do badania bezpieczeństwa ruchu drogowego w Polsce w latach 2001–2012
Authors: Weszczak Anna Danuta
Published: May 2017

Przedmiotem artykułu jest scharakteryzowanie poziomu bezpieczeństwa ruchu drogowego w poszczególnych regionach Polski w latach 2001–2012 przy wykorzystaniu modeli ekonometrycznych. W opracowaniu zostanie podjęta próba wyznaczenia społeczno-ekonomicznych determinantów bezpieczeństwa ruchu drogowego. Na podstawie literatury przedmiotu oraz raportów instytucji zajmujących się badanym zagadnieniem, a także uwzględniając dostępność danych liczbowych, za zmienne takie uznano: wydatki jednostek samorządowych w Dziale 600 – Transport i łączność, jakość dróg, wskaźnik zmotoryzowania społeczeństwa, długość sieci drogowej oraz udział pojazdów ciężkich w ogóle pojazdów. Badaniu zostały poddane trzy wskaźniki zagrożenia: liczba ofiar śmiertelnych na 1 mln mieszkańców, liczba ofiar śmiertelnych na 1 mln pojazdów oraz liczba ofiar śmiertelnych na 100 wypadków drogowych. Do estymacji parametrów równania wykorzystano modele panelowe – modele z efektami stałymi (fixed effect model, FEM) oraz modele z efektami losowymi (random effect model, REM).
Measurement of the return on investment in education and in-house training
Authors: Dziechciarz Józef
Published: May 2017

The level of awareness and acceptance of the need to enhance volume and intensity of investment in education and in-house training is increasing. This phenomenon stems from the following facts: the aging of the European societies; an intense technological and organizational progress; and a noticeable process of extension of the scope and length of professional and personal development and activity; accompanied with employees' expectations for better quality of life. The increase in the level of acceptance of the need for increased investment in education and training of employees is accompanied by new challenges, including, in the first place, the need to redefine the approach to investment in training and to the evaluation of its results. The „High-Efficiency‟ point of view, alongside the assessment of the advisability of investment in education and training within a company, raises the need to move away from the traditional system of input oriented financing (i.e. financing resources) and to move towards output oriented funding (i.e. financing results). In other words, instead of paying for teaching, companies want to pay for teaching results. This means that the companies which finance education and training, rise - in the process of assessing the training results – fundamental questions about the improvement of the efficiency of the company; and how an increase in the qualifications of workers facilitates the achievement of organizational objectives. On the other hand, the training results assessment from the participant‟s point of view includes a question about the efficiency of the supplier of educational and training programs, and whether the supplier is able to achieve the promised results. The existing business reality is that the efficiency and effectiveness assessments often do not go beyond the survey measuring the level of satisfaction and self-esteem of the participants. This, in turn, causes a visible quantitative pressures, accompanied by insufficient care for quality and inability to use modern techniques to measure the impact of education and training on business performance. As a result, many entrepreneurs treat the investment in training and education of their employees solely as an expense and a disruption of operations. This is due to the fact that managers do not see a direct effect of the investments on the performance of the company. In addition, managers fear possible hazards in the form of expense claims; loss of trained personel to competitors‟ companies, or excessive self-empowerment of the employee. The study is devoted to presentation and discussion of modern techniques measuring the effectiveness of investment in education and training. The list of methods includes an analysis based on objectives, the targeted evaluation, systemic evaluation, judicial evaluation, and assessment prior to the program.

W 2001 r. powołano jednostkę Inspekcji Transportu Drogowego (ITD), której celem jest zwiększenie bezpieczeństwa w ruchu drogowym. Celem artykułu jest odpowiedź na pytanie, na ile powołanie ITD przyczynia się do polepszenia bezpieczeństwa ruchu drogowego w Polsce. W artykule oprócz naświetlenia celów ITD, organizacji skali wypadków z udziałem ciężarowych pojazdów samochodowych, omawiamy stan ilościowy przeprowadzonych kontroli. Obserwacją obejmujemy lata 2005–2012. Artykuł pokazuje, że dzięki ostrym decyzjom administracyjnym i karnym stopniowo zmniejsza się liczba wypadków i ich skutków z udziałem ciężarowych pojazdów samochodowych.
Wybrane aspekty aktywności zawodowej kobiet w państwach UE. Analiza dla lat 2006–2014
Authors: Matuszewska-Janica Aleksandra
Published: May 2017

Jednym z założeń strategii Europa 2020 jest podwyższenie odsetka osób zatrudnionych w wieku 20–64 lata na terenie Unii Europejskiej (UE) do 75%. Realizacja tej strategii ma nastąpić między innymi poprzez zwiększenie aktywności zawodowej kobiet i osób starszych. Powiększenie zasobów siły roboczej ma swoje ekonomiczne uzasadnienie. Związane jest ono przede wszystkim z procesami demograficznymi, a zwłaszcza z powiększaniem się grupy osób w wieku poprodukcyjnym. W różnych państwach UE sytuacja związana z aktywnością zawodową kobiet kształtuje się odmiennie, dlatego też powstało pytanie o podobieństwa i różnice w zaangażowaniu kobiet na rynku pracy w poszczególnych regionach UE. Celem analizy jest grupowanie państw Unii Europejskiej ze względu na różne formy aktywności zawodowej kobiet. Klasyfikacja ta pozwoli na ocenę wzorców dotyczących aktywności zawodowej kobiet w poszczególnych krajach UE. W analizie wykorzystano metodę k-średnich. Dane pochodzą z zasobów Eurostatu z Badania Aktywności Ekonomicznej Ludności. Analizowany okres to lata 2006–2014.

Published: May 2017

Data on disability are collected in many statistical surveys, but the largest ones are censuses. The survey of disability based on census data in Poland has a long history dating back to 1921. During this period both the methodology of the survey and the scope of the data have been changing. The biggest modifications took place in 2011. NCP 2011 was the first census in Poland to be carried out by combing administrative data sources and the survey sampling method. The aim of the present study is to analyze and assess changes in the disability survey in NCP 2011 compared to NCP 2002 in terms of methodology and the scope of information.
