Abstract. The uptake of water by atmospheric aerosols has a pronounced effect on particle light scattering properties which in turn are strongly dependent on the ambient relative humidity (RH). Earth system models need to account for the aerosol water uptake and its influence on light scattering in order to properly capture the overall radiative effects of aerosols. Here we present a comprehensive model-measurement evaluation of the particle light scattering enhancement factor f(RH), defined as the particle light scattering coefficient at elevated RH (here set to 85 %) divided by its dry value. The comparison uses simulations from 10 Earth system models and a global dataset of surface-based in situ measurements. In general, we find a large diversity in the magnitude of predicted f(RH) amongst the different models which can not be explained by the site types. There is strong indication that differences in the model parameterizations of hygroscopicity and perhaps mixing state are driving at least some of the observed diversity in simulated f(RH). An important finding is that the models show a significantly larger discrepancy with the observations if RHref = 0 % is chosen as the model reference RH compared to when RHref = 40 % is used. The multi-site average ratio between model outputs and measurements is 1.64 in the former case and 1.16 in the latter. The overestimation by the models is believed to originate from the hygroscopicity parameterizations at the lower RH range which may not implement all phenomena taking place (i.e. not fully dried particles and hysteresis effects). Our results emphasize the need to consider the measurement conditions in such comparisons and recognize that measurements referred to as dry may not be dry in model terms.

Abstract. Central Asia experienced a number of significant elevational and climatic changes during the Cenozoic, but much remains to be understood regarding the timing and driving mechanisms of these changes, as well as their influence on ancient ecosystems. Here we describe the palaeoecology and palaeoclimate of a new section from the Nangqian Basin in Tibet, northwestern China, here dated as late Lutetian–Bartonian (late middle–late Eocene) based on our palynological analyses. Located on the east-central part of the Tibetan Plateau, this section is excellently placed for better understanding the palaeoecological history of Tibet following the India-Asia collision. Our new pollen record reveals that a strongly seasonal steppe-desert ecosystem characterised by drought-tolerant shrubs, diverse ferns and an underlying component of broad-leaved forests existed in east-central Tibet during the Eocene, influenced by a southern monsoon. Warming during the Middle Eocene Climatic Optimum only prompted a temporary vegetation response, while a drying signature in our pollen record after 40 Ma demonstrates that proto-Paratethys sea retreat caused widespread long-term aridification across the plateau. To better distinguish between local climatic variation and farther-reaching drivers of Central Asian palaeoclimate and elevation, we correlated key palynological sections across the Tibetan Plateau by means of established radioisotopic ages and biostratigraphy. This new palynozonation illustrates both intra- and inter-basinal floral response to plateau uplift and global climate change during the Paleogene, and provides a framework for the age assignment of future palynological studies in Central Asia. Our work highlights the ongoing challenge of integrating various deep time records for the purpose of reconstructing palaeoelevation, indicating that a multiproxy approach is vital for unravelling the complex uplift history of the Tibetan Plateau and its resulting influence on Asian climate.

Published: January 2020

Abstract. We present a 1986 through 2019 estimate of Greenland Ice Sheet ice discharge. Our data include all discharging ice that flows faster than 100 m yr−1 and are generated through an automatic and adaptable method, as opposed to conventional hand-picked gates. We position gates near the present-year termini and estimate problematic bed topography (ice thickness) values where necessary. In addition to using annual time-varying ice thickness, our time series uses velocity maps that begin with sparse spatial and temporal coverage and ends with near-complete spatial coverage and twelve-day updates to velocity. The 2010 through 2019 average ice discharge through the flux-gates is ~ 487 + −49 Gt yr−1. The 10 % uncertainty stems primarily from uncertain ice bed location (ice thickness). We attribute the ~ 50 Gt yr−1 differences among our results and previous studies to our use of updated bed topography from BedMachine v3. Discharge is approximately steady from 1986 to 2000, increases sharply from 2000 to 2005, then is approximately steady again. However, regional and glacier variability is more pronounced, with recent decreases at most major glaciers and in all but one region offset by increases in the northwest region. As part of the journal's living archive option and our goal to make an operational product, all input data, code, and results from this study will be updated as needed (when new input data are available, as new features are added, or to fix bugs) and made available at doi:10.22008/promice/data/ice_discharge and at http://github.com/mankoff/ice_discharge.

Published: January 2020

Abstract. Models that simulate evolution of polar firn are important for several applications in glaciology, including converting ice-sheet elevation-change measurements to mass change and interpreting climate records in ice cores. We have developed the Community Firn Model (CFM), an open-source, modular model framework designed to simulate numerous physical processes in firn. The modules include firn densification, heat transport, meltwater percolation and refreezing, water-isotope diffusion, and firn-air diffusion. The CFM is designed so that new modules can be added with ease. In this paper, we first describe the CFM and its modules. We then demonstrate the CFM's usefulness in two model applications that utilize two of its novel aspects. The CFM currently has the ability to run any of 13 previously published firn-densification models, and in the first application we compare those models' results when they are forced with regional climate model outputs for Summit, Greenland. The results show that the models do not agree well (spread greater than 10 %) when predicting depth-integrated porosity, firn age, or trend in surface-elevation change trend. In the second application, we show that the CFM's coupled firn-air and firn-densification models can simulate noble-gas records from an ice core better than a firn-air model alone.
Performance of GPM-IMERG precipitation products under diverse topographical features and multiple-intensity rainfall in an arid region

Published: January 2020

Abstract. The influence of topographical features and rainfall intensity on the accuracy of precipitation values estimated by earth observing satellites has attracted attention in the past decade. Assessment of rainfall products delivered by the Integrated Multi-satellitE Retrievals of Global precipitation measurement (IMERG) against ground observations has risen as an important endeavour since the accuracy of these products remain unreliable. This study comprehensively evaluated the three GPM IMERG products (near and post-real-time), over the period March 2014 to June 2018. The evaluation approaches were carried out for different seasons, rainfall intensities, topographical features, and hydrological regions over an extremely arid and semiarid country of Saudi Arabia. In general, the results confirmed that the performance of the final-run product surpassed the near-real-time products in terms of consistency and estimated errors. The evaluation results showed that for seasonal-based evaluation, the precipitation products exhibited better performance in spring and summer, while having relatively lower accuracy and higher biases in fall and winter. In addition, the results showed that the IMERG products had high performance in capturing the various rainfall intensities, with light rain having the highest accuracy. This is particularly important for arid regions as most of the rainfall is of the low-intensity class. Overall, the higher the rainfall intensity, the higher the detection errors in the IMERG products. Moreover, the hydrological evaluation results showed that the hydrological regions with low density of rain gauge stations hinders the proper evaluation of satellite products and tends to underestimate the performance of the products. Furthermore, the accuracy of the precipitation products was affected by topography to different extents. IMERG precipitation products exhibited high detection accuracy over moderate elevation areas (inland regions); whereas it had poor performance over flat plains (coastal regions) and high altitudes (foothills and mountainous regions). The outcomes of this evaluation could help developers in improving the GPM IMERG calibration to achieve better detection accuracy over arid and semiarid regions. More importantly, these results are of interest for local authorities to help manage development activities and to plan precautionary measures for extreme rainfall events.

Abstract. Changes of precipitation over the European Alps are investigated with the regional climate model MAR applied with a 7-km resolution over the period 1903–2010 using the reanalysis ERA-20C as forcing. A comparison with several observational datasets demonstrates that the model is able to reproduce the climatology as well as both the inter-annual variability and the seasonal cycle of precipitation over the European Alps. The relatively high resolution allows to estimate precipitation at high elevations. The vertical gradient of precipitation simulated by MAR over the European Alps reaches 33 % km−1 (1.21 mm.day−1.km−1) in summer and 38 % km−1 (1.15 mm.day−1.km−1) in winter, on average over 1971–2008 and shows a large spatial variability.

Statistical Postprocessing of Ensemble Forecasts for Severe Weather at Deutscher Wetterdienst
Authors: Hess Reinhold
Published: January 2020

Abstract. Forecasts of the ensemble systems COSMO-D2-EPS and ECMWF-ENS are statistically optimised and calibrated by Ensemble-MOS with a focus on severe weather in order to support warning decision management at Deutscher Wetterdienst (DWD). Ensemble mean and spread are used as predictors for linear and logistic multiple regressions to correct for conditional biases. The predictands are derived from synoptic observations and include temperature, precipitation amounts, wind gusts and many more, and are statistically estimated in a comprehensive model output statistics (MOS) approach. This paper gives an overview of DWD's postprocessing system called Ensemble-MOS together with its motivation and the design consequences for probabilistic forecasts of extreme events based on ensemble data. Long time series and collections of stations are used for significant training data that capture sufficient number of cases with observed events, as required for robust statistical modelling. Logistic regression is applied for threshold probabilities and details of its implementation including the selection of predictors with testing for significance are presented. For probabilities of severe wind gusts global logistic parameterisations are developed that depend on local estimations of wind speed. In this way robust probability forecasts for extreme events are obtained while local characteristics are preserved. Caveats of Ensemble-MOS, such as model changes and requirements for consistency, are addressed that are known from DWD's operational MOS systems.

Abstract. We present the result of the third Marine Ice Sheet Intercomparison project, MISMIP+. MISMIP+ is intended to be a test of ice flow models which include fast sliding marine ice streams and floating ice shelves and in particular a treatment of viscous stress that is sufficient for buttressing, where upstream ice flow is restrained by a downstream ice shelf. A set of idealized experiments test the models in circumstances where buttressing contributes to a stable steady state, and where a reduction in that buttressing causes ice stream acceleration, thinning, and grounding line retreat. We find that the most important distinction between models in this particular type of simulation is in the treatment of sliding at the bed, with other distinctions – notably the difference between the simpler and more complete treatments of englacial stress, but also the differences between numerical methods – taking a secondary role.
A new method for the pragmatic choice of wind models for Wind Resource Assessment in complex terrain
Authors: Barber Sarah , Schubiger Alain , Wagenbrenner Natalie , Fatras Nicolas , Nordborg Henrik
Published: January 2020

Abstract. The accuracy of the estimation of the wind resource has an enormous effect on the expected rate of return of a wind energy project. Due to the complex nature of the weather and the wind flow over the earth's surface, it can be very challenging to measure and model the wind resource correctly. For a given project, the modeller is faced with a difficult choice of a wide range of simulation tools with varying accuracies (or skill) and costs. In this work, a new method for helping wind modellers choose the most cost-effective model for a given project is developed by applying six different Computational Fluid Dynamics tools to simulate the Bolund Hill experiment and studying appropriate comparison metrics in detail. This is done by firstly defining various parameters for predicting the skill and cost scores before carrying out the simulations as well as for calculating skill and cost scores after carrying out the simulations. Weightings are then defined for these parameters, and values assigned to them for the six tools using a template containing pre-defined limits in a blind test. An iterative improvement process is applied by collecting inputs from the participants of the study. This allows a graph of predicted skill score against cost score to be produced, enabling modellers to choose the most cost-effective model without having to carry out the simulations beforehand. The most effective model is the one with the highest skill score for the lowest cost score, at the flattening-off part of the curve. The results show that this new method is successful, and that it is generally possible to apply it in order to choose the most appropriate model for a given project in advance. This is demonstrated by the good match between the shapes of the skill score against cost score curves before and after the simulations, and by the fact that the tool at the flattening-out point of the curve is the same before and after carrying out the simulations. It is also shown how important it is to take into account other factors that may affect the accuracy and costs of a wind modelling simulation as well as the quality of the aerodynamic equations and the run-time. Several improvements to the method are being worked on, by further examining the discrepancies between the predicted and actual cost and skill scores. Additionally, the method is being extended for calculating all wind directions and the Annual Energy Production, as well as to include mesoscale nesting or forcing. A large number of inputs are being collected as part of a simulation challenge in collaboration with IEA Wind Task 31. The method has a high potential to be extended to a wide range of other simulation applications.
The effect of wind direction shear on turbine performance in a wind farm in central Iowa
Authors: Sanchez Gomez Miguel , Lundquist Julie K.
Published: January 2020

Abstract. Numerous studies have shown that atmospheric conditions affect wind turbine performance; however, some findings have exposed conflicting results for different locations and diverse analysis methodologies. In this study, we explore how the change in wind direction with height (direction wind shear), a site-differing factor between conflicting studies, and speed shear affect wind turbine performance. We utilized lidar and turbine data collected from the 2013 Crop Wind Energy eXperiment (CWEX) project between June and September in a wind farm in north-central Iowa. Wind direction and speed shear were found to follow a diurnal cycle; however, they evolved differently with increasing wind speeds. Using a combination of speed and direction shear values, we found large direction and small speed shear to result in underperformance. We further analyzed the effects of wind veering on turbine performance for specific values of speed shear and found detrimental conditions on the order of 10 % for wind speed regimes predominantly located in the middle of the power curve. Focusing on a time period of ramping electricity demand (06:00–09:00 LT – local time) exposed the fact that large direction shear occurred during this time and undermined turbine performance by more than 10 %. A predominance of clockwise direction shear (wind veering) cases compared to counterclockwise (wind backing) was also observed throughout the campaign. Moreover, large veering was found to have greater detrimental effects on turbine performance compared to small backing values. This study shows that changes in wind direction with height should be considered when analyzing turbine performance.
Chaucer in China: A History of Reception and Translation
Authors: Zhang Lian
Published: January 2020

Arranged chronologically, this article presents a general picture of Chaucer reception and translation in China, and examines the development of criticism and the interaction of readers with both the original texts and their Chinese translations. By using indicators like university curricula, editions of translations and reprints, critical analyses, adaptations, and popularizations, this study shows that there have been increasing readership in medieval literature and rising admiration for the poet throughout the reception history, with occasional sharp changes. This reception pattern is determined by a combination of factors such as the intrinsic qualities of the texts, readers' concern over contemporary social issues and their own literary past, and the political and intellectual context of the nation as a whole, as well as of interaction with the outside world.

Published: January 2020

The note draws attention to the description of a manuscript of Chaucer's Treatise on the Astrolabe that appeared in a sale catalogue in 1843. It suggests that the description cannot be identified with any of the manuscripts currently recorded and that it therefore provides evidence of a further copy of this work.
O romance contemporâneo e o cânone na escola: visões e revisões
Authors: Martinelli Filho Nelson
Published: January 2020

Este artigo tem como intuito trazer para discussão a leitura e o estudo, no âmbito específico do Ensino Médio, de romances publicados a partir das últimas décadas a fim de destacar aspectos da literatura atual que ponham em xeque as fronteiras e os limites tradicionalmente atribuídos a esse gênero na escola, pautados em suas relações com o cânone. Nesse sentido, propomos situar o debate considerando a realidade de docentes e alunos da Educação Básica a fim de contribuir para a revisão de conceitos enrijecidos acerca do romance contemporâneo por meio de, em especial, uma revisão do espectro conceitual do que se apresenta nos livros didáticos, ampliando os horizontes de trabalho com esse gênero em sala de aula. Para tanto, tomaremos como base o pensamento de Giorgio Agamben (2009) e de Karl Erik Schøllhammer (2009) sobre o contemporâneo. Também contribuirão para este estudo os trabalhos de Cereja (2004), Dalvi (2013), Lajolo (2016) e Oliveira (2013) acerca das relações entre literatura e escola.
Literatura infantil em contextos educativos formais e não formais: a técnica do voo
Authors: Mendes Teresa
Published: January 2020

RESUMO: No presente artigo, discute-se a problemática da literatura infantil em contextos educativos formais e não formais relevando o papel do adulto-mediador na promoção da fruição estética e da compreensão leitora atendendo aos níveis de desenvolvimento da leitura e às experiências vivenciais do potencial recetor infantil. Preconiza-se a liberdade de seleção dos livros que o adulto considera mais adequados para abordar com as crianças, apesar dos constrangimentos legais que se lhe colocam no que diz respeito às diretrizes ministeriais plasmadas nos documentos programáticos e nas orientações curriculares para a sua prática educativa e pedagógica. Procura-se assim demonstrar que o agente educativo não deve apenas cingir-se à abordagem didática de obras obrigatórias nos referenciais que regem a sua prática letiva, mas pode e deve ir mais além, convocando textos e autores que se lhe afigurem relevantes para incutir o prazer da leitura e potenciar a educação literária dos mais novos, de modo a que se tornem, gradativamente, leitores competentes e críticos, capazes de extrair significados plurais das obras que lhe são preferencialmente dirigidas ou de que eles se apropriam por via da relação afetiva com o ato de ler.

Paisagem e Geossistema: Epistemologia, Método e Cartografia
Authors: Morais Júnior Hélio de Souza , Pimentel Marcia Aparecida da Silva
Published: January 2020

A conjuntura epistêmica em que a ciência geográfica se encontra tem evidenciado debates importantes sobre paisagem e geossistema em várias escolas do pensamento geográfico (russa, europeia, estadunidense e latino-americana). A reflexão epistemológica, o método e os critérios para cartografar são os elementos principais desta breve reflexão sobre paisagem e geossistema. O objetivo deste artigo é debater o conceito da categoria paisagem, compreendendo esta categoria como uma ferramenta qualificada para a análise do espaço geográfico – pois o fundamento epistemológico sobre a paisagem será a estrutura óssea do método científico, o método será o percurso da reflexão, da análise e do discurso sobre o problema (ou objeto), cuja deficiência não é cartográfica e sim do próprio método, e que por sua vez perpassa pela questão epistemológica. Portanto, durante o desenvolvimento do conceito de paisagem e o nascimento da abordagem geossistêmica, ambas se tornaram a conexão mais perfeita dos estudos geográficos atualmente, que sugerem um avanço ou uma quebra paradigmática no seio do pensamento geográfico contemporâneo.
A Internet como Instrumento de Pesquisa e de Aprendizagem: uma Análise a partir do Ensino de Geografia
Authors: Coutinho Severino Alves
Published: January 2020

Este artigo está pautado num estudo voltado ao ensino de Geografia e o uso da internet como fonte de informação e de pesquisa, tendo em vista sua acessibilidade enquanto interface tecnológica importante para o desenvolvimento de atividades pedagógicas que permita a sua utilização não apenas como mera atratividade, mas, sobretudo, como veículo de comunicação que expressa em tempo real uma diversidade de imagens e informações que podem subsidiar o planejamento e motivar docentes e discentes, gerando mais qualidade no processo de ensino aprendizagem. Ademais, enquanto recurso didático tecnológico, a internet oferece um diversificado fluxo de trabalhos acadêmicos em formato digital, possibilitando a leitura e a reflexão, bem como ainda servindo como suporte teórico para estudos propostos pela disciplina. Sob esse viés de análise, esse artigo foi estruturado a partir de uma pesquisa de campo realizada na Escola Estadual Professora Ocila Bezerril, no município de Montanhas – RN, onde foram aplicados questionários aos alunos do 1º ano do Ensino Médio, buscando verificar se a internet tem sido utilizada como instrumento que proporciona aprendizagem no ensino de Geografia, bem como se os docentes têm orientado estudos que contemplem o uso dessa tecnologia em sala de aula. Pela análise dos dados, constatou-se que apesar dos alunos serem a favor da inserção deste recurso no contexto escolar, nem todos os educadores têm como prática lecionar Geografia em consonância com a dinâmica interativa da internet.
Endovascular Treatment for Intracranial Aneurysms: A Nationwide Survey in Korea
Authors: Kim Jung-Jae , Cho Kwang-Chun , Jung Woo Sang , Suh Sang Hyun
Published: January 2020

Purpose: In Korea, endovascular treatment (EVT) for intracranial aneurysms (IAs) has increased steadily. We conducted a nationwide survey to evaluate the current status of EVT for IAs and to identify treatment preference in the real world.Materials and Methods: A Google online survey was distributed to representative clinicians at hospitals treating IAs, where members of Korean Society of Interventional Neuroradiology (KSIN). The data was collected from October 2017 to December 2017. The responding hospitals were divided into 2 groups (tertiary and non-tertiary hospitals). And variable factors involved in decision making for treatment were evaluated.Results: In total, 73 hospitals (tertiary: 37, non-tertiary: 36) responded to the survey. Most hospitals that responded had over 100 cases of diagnostic angiography (93%) and over 50 cases of EVT for IAs (74%) performed in 2016. The proportion of EVT for ruptured aneurysms in non-tertiary hospitals was significantly higher than tertiary hospitals (49% vs. 9%). The proportion of EVT for unruptured aneurysms at non-tertiary hospitals was significantly higher than tertiary hospitals (66% vs. 44%). Most physicians tended to make decision for treatment on location, shape, and size of unruptured IAs and patients’ age, more than the results from previous clinical trials for unruptured IAs. Although EVT was preferred for older patients (age >70) with unruptured IAs (99%), surgical clipping was still considered as the first treatment of choice for younger patients (age 30 to 50 years) at considerable rates (56%). Over two-thirds of respondents preferred surgical clipping for middle cerebral artery aneurysms, while EVT was preferred initially at other locations.Conclusion: This nationwide survey showed that EVT is considered as the first treatment modality for IAs and there is a discrepancy between current guidelines and real-world practice for decision making of treatment options.

Infantilization of the elderly not only in the language sphere – research report
Authors: Szostakowska Katarzyna
Published: January 2020

The presented article concerns the phenomenon of infantilization of the elderly in many areas of everyday by their family carers. Infantilization means treating an adult like a child. In the sphere of language, this phenomenon is called baby-talk. Often infantilization of the elderly concerns the sphere of communication. The author of the article shows that not only during conversations they are treated as children. Family carers showed signs of infantilization, referring to the care and nursing of the elderly under their care. This article is an excerpt from a broader study of family carers for the elderly. The study was conducted with 20 carers of the elderly using the unstructured interview method in the Kuyavian-Pomeranian Voivodeship. The analysis of the research material was performed using the MAXQDA software. The result of a broad analysis is the research report presented in this study, which shows that infantilization is multidimensional and nonconscious. It results from the lack of preparation of the family carers for the role of a caregiver. Due to their insufficient knowledge about looking after an old person, the careres are forced to base their knowledge on their experience as parents.
Multiple victimisation in the opinion of hospitalized seniors with disabilities – preliminary evaluation of the phenomenon
Authors: Chimicz Dorota
Published: January 2020

The problem of violence is still a challenge for all environments involved in providing support and assistance for families. Despite many social and governmental programs to counteract the abuse of family members, violence is still present in the everyday life of many women, children, the elderly and the disabled. This study focuses primarily on the old age and the disability related to it, which are important risk factors that expose to violence and degrading treatment. The aim of the research was a preliminary diagnosis of the occurrence of simultaneous experience of many forms of violence by seniors with disabilities. The obtained results indicate that 36% of the seniors with disabilities participating in the study experience multiple victimization and that the level of elders’ education, their place of residence and financial situation show a statistically significant relationship with the experience of multiple victimisation.
The rights of elderly people and the social exclusion
Authors: Łuszczyńska Maria
Published: January 2020

The issue of the elderly people’s rights has been discussed more and more often in the broader context of human rights. There is much evidence from social life that these rights are not being respected to the extent they should be. Securing and respecting the rights of older the elderly is becoming a challenge for state authorities that uphold human rights and create the directions of social policy for the rights protection. It is especially important as the elderly people due to their age, health status, weakened social position, rarely become advocates of their own interests. They are victims of an unobvious and often invisible process of marginalization and self-exclusion from an active social life.
The aim of this article is to sketch the phenomenon of the marginalization of the elderly in the context of mechanisms related to their functioning on the one hand, and age, and on the other to social attitudes towards seniors.

W PRACY SŁUŻBY PRASOWEJ
Authors: Konieczny Marcin Krzysztof
Published: January 2020

W artykule zostały podjęte rozważania nad ważną rolą, jaką
zaczynają coraz częściej spełniać różne media społecznościowe w codziennej służbie rzeczników prasowych.
Zmiany, jakie można zaobserwować
w zakresie internetowych kanałów
przesyłania informacji, noszą wszelkie
znamiona rewolucji, której rozmiarów
nie można jeszcze precyzyjnie określić.
Nie rezygnując z tradycyjnych kanałów
przekazywania treści społeczeństwu
(prasa, konferencje prasowe, wywiady autoryzowane, artykuły, audycje
w stacjach radiowych i wizyty w telewizji), można zastanawiać się nad coraz większymi możliwościami, jakie
przynoszą ze sobą social media i jaką
nową rzeczywistość stwarzają. Internet
jest przede wszystkim medium interaktywnym, gdzie wiele informacji jest
przekazywanych, a nawet redagowanych, przez amatorów. Chociaż działają w dobrej wierze, to jednak nie mają
odpowiedniego przygotowania do pracy
z mediami społecznościowymi. Inaczej
jest w przypadku profesjonalnie wykształconych i przygotowanych ofi -
cerów prasowych. Najczęściej znają
świetnie zarówno problemy dziennikarzy, jak i orientują się w wewnętrznych
sprawach organów ścigania, są najbliżej zdarzeń i mają wiedzę z pierwszej
ręki — od funkcjonariuszy pełniących
służbę w terenie.
Policyjni rzecznicy prasowi mogą
początkowo przejawiać pewien konserwatyzm z racji bardzo delikatnej
materii, w obrębie której działają, jednak ostatecznie wydaje się, że niektóre
spośród przynajmniej kilkudziesięciu
światowych mediów społecznościowych
znacząco wpłyną pozytywnie na pracę
służbę prasową policji oraz służb specjalnych.
FUNKCJA WYKRYWCZA I DOWODOWA W POSTĘPOWANIU
KARNYM. ZARYS PROBLEMATYKI. CZĘŚĆ II
Authors: Zdybel Roman
Published: January 2020

Artykuł odzwierciedla aktualną problematykę miejsca, roli i znaczenia funkcji wykrywczej w postępowaniu karnym w zakresie skutecznego
typowania źródeł dowodowych do procesowego wykorzystania w ramach prerogatyw funkcji dowodowej udowadniania
w indywidualizacji zarzucanego sprawcy
popełnienia inkryminowanego zdarzenia. Synchronizacja instrumentów prawnych obu funkcji dla podniesienia wykrywalności uciążliwej społecznie i gospodarczo przestępczości w neutralizacji
skali oraz dynamiki niebezpiecznych
i zorganizowanych grup przestępczych
jest nieodzowna i stanowi wyzwanie dla
całej globalizacji przestępczości. Zawężanie wyodrębnienia funkcji wykrywczej
tylko do osiągnięć nauki kryminalistyki
bez umiejscowienia bardziej operatywnej
i skutecznej funkcji wykrywczej w postępowaniu karnym (krajowej przestrzeni
prawnej) pomimo uzbrojenia jej w ustawowe prerogatywy jest nieporozumieniem oraz marginalizowaniem całego
oczekiwanego społecznie i akceptowanego procesu skutecznego oraz efektywnego zwalczania przestępczości i kwestionowania sprawności działania organów
ścigania oraz wymiaru sprawiedliwości.
Szkolenie w zakresie
zasad użycia siły
sposobem na wyeliminowanie
syndromu Nangar Khel
Authors: Mendel Wojciech
Published: January 2020

Autor analizuje zjawisko występowania lęku przed użyciem siły w sytuacjach bojowych,
określane przez polskich żołnierzy syndromem Nangar Khel. Dowodzi tezy,
że lęk przed ewentualnymi konsekwencjami prawnymi nieuzasadnionego użycia
siły wynika z niedostatecznego poziomu wiedzy oraz niedostatecznych umiejętności
żołnierzy zastosowania w praktyce zasad użycia siły. Jako metodę wyeliminowania
wspomnianego syndromu postuluje prowadzenie treningów w zakresie zasad
stosowania siły.
One-stage nipple and breast reconstruction using a deep inferior epigastric perforator flap after a skin-sparing mastectomy

Published: January 2020

Background Nipple reconstruction is usually performed as a delayed procedure in patients with breast cancer who undergo skin-sparing mastectomy and breast reconstruction surgery using a deep inferior epigastric perforator (DIEP) flap. The authors designed this study to evaluate the utility of breast reconstruction based on a DIEP flap and immediate nipple reconstruction.

Methods A retrospective review was conducted of all patients who underwent breast reconstruction performed by a single plastic surgeon from October 2016 to June 2018. Through a questionnaire and chart review, we compared surgical results and complications in cases of single-stage nipple reconstruction after skin-sparing mastectomy (n=17) with patients who underwent delayed nipple reconstruction after skin-sparing mastectomy, modified radical mastectomy, or simple mastectomy (n=7).

Results In a subjective analysis using clinical photos, the immediate nipple reconstruction group had higher scores than their counterparts in an evaluation of the nipple-areolar complex (NAC) (NAC placement, 3.34 vs. 3.04; nipple projection, 3.05 vs. 3.03; nipple size, 3.30 vs. 3.29). No significant differences between the groups were found in terms of complications.

Conclusions Simultaneous nipple reconstruction is a reliable surgical method with economic advantages. No differences were found in terms of outcomes and complications in comparison to delayed reconstruction. Therefore, surgeons can consider simultaneous nipple reconstruction without particular concerns about asymmetry or necrosis.
Ultrasonic dissection versus electrocautery for immediate prosthetic breast reconstruction
Authors: Lee Dongeun , Jung Bok Ki , Roh Tai Suk , Kim Young Seok
Published: January 2020

Background Ultrasonic dissection devices cause less thermal damage to the surrounding tissue than monopolar electrosurgical devices. We compared the effects of using an ultrasonic dissection device or an electrocautery device during prosthetic breast reconstruction on seroma development and short-term postoperative complications.

Methods We retrospectively reviewed the medical records of patients who underwent implant-based reconstruction following mastectomy between March 2017 and September 2018. Mastectomy was performed by general surgeons and reconstruction by plastic surgeons. From March 2017 to January 2018, a monopolar electrosurgical device was used, and an ultrasonic dissection device was used thereafter. The other surgical methods were the same in both groups.

Results The incidence of seroma was lower in the ultrasonic dissection device group than in the electrocautery group (11 [17.2%] vs. 18 [31.0%]; P=0.090). The duration of surgery, total drainage volume, duration of drainage, overall complication rate, surgical site infection rate, and flap necrosis rate were comparable between the groups. Multivariate analysis revealed that the risk of seroma development was significantly lower in the ultrasonic dissection device group than in the electrocautery group (odds ratio for electrocautery, 3.252; 95% confidence interval, 1.242–8.516; P=0.016).

Conclusions The findings of this study suggest that the incidence of seroma can be reduced slightly by using an ultrasonic dissection device for prosthesis-based breast reconstruction. However, further randomized controlled studies are required to verify our results and to assess the cost-effectiveness of this technique.
