Post-Truth Politics in the UK's Brexit Referendum
Authors: Marshall Hannah , Drieschova Alena
Published: February 2020

The term post-truth became the 2016 Oxford Dictionary word of the year, yet many scholars question whether the term signals anything new, or whether post-truth is just lying, which has always been a part of politics and media. This paper contributes to this discussion by critically evaluating the extent to which the Brexit referendum, the UK's vote to exit the European Union, was based on post-truth politics. The paper develops the argument that Brexit is a key example of post-truth politics, and that two key factors ushered in this new form of politics into the UK: 1) technological changes associated with social media, which lead to a situation in which a significant portion of the population acquire their news online, while anybody can post anything online without checks on the accuracy of the claims; 2) a growing distrust in democratic institutions, political elites, expertise, and traditional media gatekeepers which leads, in turn, to a loss of trust in established expert knowledge, leaving the population willing to rely on information originating from questionable sources. This combination of a decline in trust of politicians and experts with social media reliance, drove the British public to emotionally charged, value-based decision making to a greater extent than before, which thus supports the claim that post-truth politics is indeed a novel phenomenon. Our analysis of the Brexit referendum raises the need for scholars to study the daily activities of the population and focus on its role as an active regime shaper.
Developmental trajectory of communication repair in children with Fragile X Syndrome
Authors: Fielding-Gebhardt Heather , Warren Steven F , Brady Nancy C
Published: February 2020

Background and aims

The development of communicative competence requires both language and social skills. The ability to repair following a communication breakdown is critical for continued conversational interchange and to ensure comprehension of bids for communication. Communication repair demonstrates adequate language and social skills. Children with Fragile X Syndrome have difficulty with language development and social skills, which may result in delays or deficits in repair. Repair may be additionally impaired in children with Fragile X Syndrome and co-morbid autism. This study examined the development of repair in children with Fragile X Syndrome from toddlerhood into middle childhood.

Methods

Fifty-five children with Fragile X Syndrome and their biological mothers participated. Data were collected during in-home visits approximately every 18 months. Videotaped mother–child interactions were collected, as well as standardized assessments of language, social skills, and autism symptomology.

Results

Children with Fragile X Syndrome acquired the ability to repair at 90% mastery by three-and-a-half years of age. Multilevel logistic regressions predicting probability of repair indicated marginally significant effects of mean length of utterance and number of different words, and significant effects of global social skills and autism symptomology. Effect sizes were small to moderate.

Conclusions

Ability to repair was measured in a naturalistic setting, which allowed children with Fragile X Syndrome to utilize repairs in their daily interactions. Although children with Fragile X Syndrome may have delayed development of repair relative to typically developing expectations, in general they nonetheless catch up and demonstrate a robust ability to repair by three-and-a-half years of age. However, this study provides evidence that individual differences in language and social skills may influence ability to repair in children with Fragile X Syndrome. Finally, the relationship between autism symptoms and repair remains unclear, necessitating further exploration. Implications: Given the noted delay in repair in young children with Fragile X Syndrome, clinicians working with this population should target development of this skill as early as possible to maximize successful social interactions. This may be particularly necessary for children with Fragile X Syndrome and co-morbid autism.
Targeting Subsets of Mammalian Neurons
Authors: Zemelman Boris V.
Published: February 2020

Functional dissection of mammalian neuronal circuits depends on accurate targeting of constituent cell classes. Transgenic mice offer precise and predictable access to genetically defined cell populations, but there is the pressing need to target neuronal assemblies in species less amenable to genomic manipulations, such as the primate, which is an important animal model for human perception, cognition, and action. We have developed several virus-based methods for accessing all forebrain inhibitory interneurons as well as the major excitatory and inhibitory neuron subclasses. These methods rely on the wealth of emerging single-cell transcriptome data and harness gene expression variations to refine neuron targeting. Our approach enables nuanced functional studies, including in vivo imaging and manipulation, of the diverse cell populations of the mammalian neocortex, and it represents a timely blueprint for transgenics-independent interrogation of functionally significant cell classes.
The use of deuterium-labeled gamma-aminobutyric (D6-GABA) to study uptake, translocation, and metabolism of exogenous GABA in plants
Authors: Hijaz Faraj , Killiny Nabil
Published: February 2020

Background

Exogenous application of gamma-aminobutyric acid (GABA) could relieve stress symptoms caused by abiotic stresses including anoxia, heat and cold shock, drought, and salt. However, studying translocation and metabolism of exogenous GABA is challenged by the presence of endogenous GABA.

Results

Herein, we used D6-GABA in order to investigate the uptake, translocation, and the metabolism of exogenous GABA in Mexican lime (Citrus aurantifolia) seedlings using gas chromatography-mass spectrometry (GC–MS). The GC–MS analysis showed that D6-GABA could be easily distinguished from the non-labeled GABA after methyl chloroformate (MCF) derivatization. The D6-GABA was detected in the cortex (phloem), inner stem (xylem), and leaves after root drench. Girdling did not affect the translocation of D6-GABA, indicating that it is mainly translocated via the xylem. In addition, D4-labled succinic acid was detected in D6-GABA-treated plants, indicating that exogenous GABA was metabolized to succinic acid. The half-life of D6-GABA in citrus was about 1.3 h, indicating a quick conversion to succinic acid.

Conclusion

The use of D6-GABA offers a valuable tool to study the translocation and metabolism of GABA in plants. D6-GABA and its metabolite (D4-succinic acid) can be easily distinguished from the endogenous GABA and succinic acid using GC–MS.
Promoting sport participation during early parenthood: a randomized controlled trial protocol
Authors: Grant Stina J. , Beauchamp Mark R. , Blanchard Chris M. , Carson Valerie , Rhodes Ryan E.
Published: February 2020

Background

Adult participation in sport is associated with important positive psychosocial outcomes. Despite the multitude of benefits that have been linked to sport participation, adult participation rates in Canada remain low. Parents with young children represent a demographic that may benefit considerably from sport participation, given the prevalence of inactivity coupled with increased levels of psychosocial distress among this group. This study aims to evaluate the efficacy of two types of sport participation (individual sport and team sport) on key psychosocial outcomes compared with a “personal time” control condition among parents with young children.

Methods/design

The three-arm, parallel design, single-blind, randomized controlled trial will compare a team sport condition, an individual sport condition, and a “personal time” control condition over 3 months. Parents are eligible if they have a child under 13 years of age, are not participating in a sport at baseline, and are not meeting Canadian Physical Activity Guidelines. Psychosocial variables (quality of life, relationship satisfaction, social functioning, parental stress, and enjoyment) will be assessed at baseline, 6 weeks, and 3 months. A total of 161 parents have been recruited thus far from the Greater Victoria region in British Columbia, Canada. The study is ongoing with a target goal of 240 participants and an anticipated completion date of December 2021.

Discussion

This protocol describes the implementation of a randomized controlled trial that evaluates the effectiveness of sport participation for increasing positive psychosocial outcomes. This information could prove useful for future adult sport participation and potentially inform public health initiatives involving parents and families.

Gene expression profiles of bovine uninucleate trophoblast cells and trophoblast giant cells: a data note
Authors: Polei Marina , Günther Juliane , Koczan Dirk , Fürbass Rainer
Published: February 2020

Objectives

In the bovine placenta, intimate fetomaternal contact is restricted to placentomes. Within the placentomes fetal chorionic villi interdigitate with corresponding maternal caruncular crypts. The trophoblast epithelium covering the chorionic villi consists of 80% uninucleate trophoblast cells (UTCs) and 20% trophoblast giant cells (TGCs). TGCs migrate toward the endometrium and fuse with endometrial cells to form short-lived fetomaternal hybrid cells. Thereby the TGCs transport molecules of fetal origin across the placental barrier into the maternal compartment. The UTC/TGC ratio is constant during pregnancy because UTCs can differentiate into new TGCs to replace spent TGCs. However, our understanding of this differentiation process was sparse. Therefore, we collected the data to study the gene expression profiles in UTCs and TGCs and to identify differently expressed genes between the two trophoblast cell populations. Using Gene Ontology analysis, we wanted to identify biological processes and pathways that play an important role in the differentiation of UTCs into TGCs.

Data description

Bovine placentas were from days 118 to 130 of gestation. We obtained virtually pure UTCs and TGCs using a fluorescence-activated cell sorting (FACS) method. Total RNA was extracted from the UTC and TGC isolates, labeled and hybridized to Affymetrix Bovine Gene 1.0 ST Arrays.
Identifying correctness data scheme for aggregating data in cluster heads of wireless sensor network based on naive Bayes classification
Authors: Chu Shu-Chuan , Dao Thi-Kien , Pan Jeng-Shyang , Nguyen Trong-The
Published: February 2020

Wireless sensor network (WSN) has been paid more attention by scholars due to the practical communication of a system of devices to transfer information gathered from a monitored field through wireless links. Precise and accurate data of aggregating messages from sensor nodes is a vital demand for a success WSN application. This paper proposes a new scheme of identifying the correctness data scheme for aggregating data in cluster heads in hierarchical WSN based on naive Bayes classification. The collecting environmental information includes temperature, humidity, sound, and pollution levels, from sensor nodes to cluster heads that classify data fault and aggregate and transfer them to the base station. The collecting data is classified based on the classifier to aggregate in the cluster head of WSN. Compared with some existing methods, the proposed method offers an effective way of forwarding the correct data in WSN applications.
Existence of multiple positive solutions for a truncated Kirchhoff-type system involving weight functions and concave–convex nonlinearities
Authors: Lou Qingjun , Qin Yupeng
Published: February 2020

We consider the combined effect of concave–convex nonlinearities on the number of solutions for an indefinite truncated Kirchhoff-type system involving the weight functions. When $\alpha+ \beta<4$α+β<4, since the concave-convex nonlinearities do not satisfy the mountain pass geometry, it is difficult to obtain a bounded Palais–Smale sequence by the usual mountain pass theorem. To overcome the problem, we properly introduce a method of Nehari manifold and then establish the existence of multiple positive solutions when the pair of the parameters is under a certain range.
Infection control link nurse programs in Dutch acute care hospitals; a mixed-methods study
Authors: Dekker Mireille , van Mansfeld Rosa , Vandenbroucke-Grauls Christina , de Bruijne Martine , Jongerden Irene
Published: February 2020

Background

Infection control link nurse programs show considerable variation. We report how Dutch link nurse programs are organized, how they progress, and how contextual factors may play a role in the execution of these programs.

Methods

This mixed-methods study combined a survey and semi-structured interviews with infection control practitioners, based on items of the Template for Intervention Description and Replication (TIDieR) checklist.

Results

The Netherlands has 74 hospitals; 72 infection control practitioners from 72 different hospitals participated in the survey. Four of these infection control practitioners participated in interviews. A link nurse program was present in 67% of the hospitals; responsibility for 76% of these programs lied solely with the infection prevention and control team. The core component of most programs (90%) was education. Programs that included education on infection prevention topics and training in implementation skills were perceived as more effective than programs without such education or programs where education included only infection prevention topics.

The interviews illustrated that these programs were initiated by the infection prevention team with the intention to collaborate with other departments to improve practice. Content for these programs was created at the time of their implementation. Infection control practitioners varied in their ability to express program goals and to engage experts and key stakeholders.

Conclusions

Infection control link nurse programs vary in content and in set up. Programs with a clear educational content are viewed as more successful by the infection control practitioners that implement these programs.
Diet and behavioral habits related to oral health in eating disorder patients: a matched case-control study
Authors: Johansson Ann-Katrin , Norring Claes , Unell Lennart , Johansson Anders
Published: February 2020

Background

Patients suffering from eating disorders (ED) have a substantially increased risk for developing poor oral health. In this regard, dietary habits in combination with obsessive behavior as well as the expression and intensity of the disease are of utmost importance. This study aimed to investigate diet and behavioral habits in patients with ED compared to healthy controls.

Methods

All patients who initiated treatment in an ED clinic during 1 year were invited to participate in the study. Sixty-five patients were admitted out of which 54 agreed to participate: 50 women and 4 men, mean age 21.5 years, range 10–50 years. From a public dental health clinic, 54 sex-and age-matched controls where selected. In all participants a comprehensive questionnaire was completed. ED patients were analyzed with respect to their self-perceived disease state: when they felt “relatively good” (ED-good) and “bad” (ED-bad) as well as if they reported vomiting or not.

Results

The ED-good patients reported significantly higher intake of caffeine-containing and cola light soft drinks and both study groups reported a lower intake of regularly sweetened carbonated drinks compared to controls. ED-bad reported significantly lower intake of number of meal and sweet intake while both study groups brushed their teeth more frequently than controls. As regards awareness of detrimental dietary intake and the possible risk for oral health complications did not differ between patients and controls except that the ED groups were more aware that vomiting and brushing thereafter could damage their teeth. ED patients went less often to the dentist for regular checkups than controls. Vomiting ED patients differed in several of the parameters related to dietary and other behaviors compared to no vomiting subjects. According to regression analyses and compared to healthy controls, predictive variables for ED-good were: higher intake of caffeine containing drinks (OR 1.34, CI 1.10–1.64) and lower intake of regular soft drinks (OR 0.57, CI 0.35–0.94). For ED-bad, lower frequency intake of lunch meals (OR 0.59, CI 0.39–0.88) and sweet biscuits were predictive (OR 0.15, CI 0.05–0.48).

Conclusions

ED patients present a number of dietary and other types of behavior that are potentially harmful for oral health. It is important to retrieve reports on the ED behaviors in both relatively good and bad disease state in order for the medical team to prescribe adequate advice and treatment.
The development and validation of a ‘flux-corrected transport’ based solution methodology for the plasmasphere refilling problem following geomagnetic storms
Authors: Chatterjee K. , Schunk R. W.
Published: February 2020

The refilling of the plasmasphere following geomagnetic storms remains one of the longstanding and interesting problems in ionosphere–magnetosphere coupling research. The objective of this paper is the formulation and development of a one-dimensional (1D) refilling model using the flux-corrected transport method, a numerical method that is well-suited to handling problems with shocks and discontinuities. In this paper, the developed methodology has been validated against exact, analytical benchmarks, and good agreement has been obtained between these analytical benchmarks and numerical results. The objective of this research is the development of a three-dimensional (3D) multi-ion model for ionosphere–magnetosphere coupling problems in open and closed line geometries.
(U–Th)/He thermochronometric mapping across the northeast Japan Arc: towards understanding mountain building in an island-arc setting
Authors: Fukuda Shoma , Sueoka Shigeru , Kohn Barry P. , Tagami Takahiro
Published: February 2020

Topographic relief in arc-trench systems is thought to be formed by plate subduction; however, few quantitative investigations have so far been reported, with respect to the related mountain building process. This study applies apatite and zircon (U–Th)/He thermochronometry (AHe, ZHe, respectively) to Cretaceous granite rocks in the north part of the northeast (NE) Japan Arc to reveal its cooling/denudation history. Weighted mean AHe ages ranging from 88.6 to 0.9 Ma and ZHe ages from 83.9 to 7.4 Ma were determined for 10 rock samples. Using the AHe data, denudation rates were obtained for each sample. On the fore-arc side, denudation rates of < 0.05 mm/year were calculated, indicating a slow denudation process since the Paleogene. However, in the Ou Backbone Range and on the back-arc side, denudation rates at > 0.1–1.0 mm/year were computed, probably reflecting a recent uplift event since ~ 3–2 Ma. These data indicate a clear contrast in thermal and denudation histories between the tectonic units in this study area, similar to that previously reported from the southern part of NE Japan Arc. A comparison of the thermal/denudation histories between the N- and S- traverses, revealed the arc-parallel trend, the uplift model of the volcanic arc, and some minor variations of thermal/denudation histories in each tectonic unit. This study offers some further insights into the understanding of tectonic processes in an island-arc setting.
Complete remission of multiple liver metastases with only partial response of the primary rectal cancer after neoadjuvant chemotherapy
Authors: Miura Satomi , Ito Kyoji , Takemura Nobuyuki , Mihara Fuminori , Kiyomatsu Tomomichi , Kokudo Norihiro
Published: February 2020

Background

Colorectal cancer is commonly diagnosed among the Japanese population, and various strategies in treating the colorectal liver metastasis have been introduced over the years. Here, we present a case of colorectal liver metastases in which we devised a multidisciplinary treatment plan for a better prognosis.

Case presentation

We report a case of a 44-year-old female who developed rectal cancer with advanced synchronous liver metastases and was treated by a liver-first surgical approach following neoadjuvant chemotherapy. At diagnosis, there were 12 bilobular lesions in the liver, and the primary rectal cancer was asymptomatic and unprogressive. We adopted a liver-first strategy because the control of the liver metastases was considered the key prognostic factor. Furthermore, because the lesions were highly progressive, we planned neoadjuvant systemic chemotherapy first to provide an observational period to identify potential new metastatic lesions that were refractory to systemic chemotherapy or contraindicative for surgical resection. We administered two courses of S-1 + oxaliplatin (SOX)+ bevacizumab (BV) and an additional course of SOX without BV as neoadjuvant chemotherapy in preparation for surgery. This resulted in a prominent minimalization of colorectal liver metastases, and no other remote metastasis was observed. Then, surgical resection of the colorectal liver metastases was performed safely, and the pathological result revealed complete remission of all tumors by neoadjuvant chemotherapy. The primary tumor in the colon was successfully resected 2 months after the hepatectomy. Although the patient experienced a recurrence in two different sites in the lungs 10 months after resection of the primary rectal lesion, these metastases were successfully resected after diagnosis. The patient is alive with no signs of recurrence 3 years after the diagnosis of colorectal cancer with synchronous liver metastases.

Conclusions

The combination of a liver-first strategy and neoadjuvant chemotherapy is a possible treatment of choice to cure colorectal cancer with simultaneous advanced colorectal liver metastases.

Published: February 2020

PURPOSE

Preoperative chemoradiotherapy may improve the radical resection rate for resectable or borderline resectable pancreatic cancer, but the overall benefit is unproven.

PATIENTS AND METHODS

In this randomized phase III trial in 16 centers, patients with resectable or borderline resectable pancreatic cancer were randomly assigned to receive preoperative chemoradiotherapy, which consisted of 3 courses of gemcitabine, the second combined with 15 × 2.4 Gy radiotherapy, followed by surgery and 4 courses of adjuvant gemcitabine or to immediate surgery and 6 courses of adjuvant gemcitabine. The primary end point was overall survival by intention to treat.

RESULTS

Between April 2013 and July 2017, 246 eligible patients were randomly assigned; 119 were assigned to preoperative chemoradiotherapy and 127 to immediate surgery. Median overall survival by intention to treat was 16.0 months with preoperative chemoradiotherapy and 14.3 months with immediate surgery (hazard ratio, 0.78; 95% CI, 0.58 to 1.05; P = .096). The resection rate was 61% and 72% ( P = .058). The R0 resection rate was 71% (51 of 72) in patients who received preoperative chemoradiotherapy and 40% (37 of 92) in patients assigned to immediate surgery ( P < .001). Preoperative chemoradiotherapy was associated with significantly better disease-free survival and locoregional failure-free interval as well as with significantly lower rates of pathologic lymph nodes, perineural invasion, and venous invasion. Survival analysis of patients who underwent tumor resection and started adjuvant chemotherapy showed improved survival with preoperative chemoradiotherapy (35.2 v 19.8 months; P = .029). The proportion of patients who suffered serious adverse events was 52% versus 41% ( P = .096).

CONCLUSION

Preoperative chemoradiotherapy for resectable or borderline resectable pancreatic cancer did not show a significant overall survival benefit. Although the outcomes of the secondary end points and predefined subgroup analyses suggest an advantage of the neoadjuvant approach, additional evidence is required.
The hype in spectral imaging
Authors: Polder Gerrit , Gowen Aoife
Published: February 2020

Hyperspectral imaging is currently a very well-known and much used technology for measuring features in
different fields, such as chemistry, geology, medicine, food and agriculture, either spaceborne (satellites), airborne
(drones) or at close proximity (e.g. field scanning, industrial sorting lines or microscopy). Its background is two-fold, and it
can be considered as a special case of spectroscopy (“imaging spectroscopy”) or a special case of imaging (“spectral
imaging”). Current practice is to use adjectives such as multi and hyper added to “spectral imaging” in order to characterise
the number of wavelength bands. In this paper we propose the community to use scientifically sound terminology, like
“imaging spectroscopy” or “spectral imaging”, without using ambiguous adjectives. Further, we encourage the community
to define and agree upon clear adjectives to describe the number of variables in the naming of our imaging
technique.
Monopsony in Online Labor Markets
Authors: Dube Arindrajit , Jacobs Jeff , Naidu Suresh , Suri Siddharth
Published: February 2020

Despite the seemingly low switching and search costs of on-demand labor markets like Amazon Mechanical Turk, we find substantial monopsony power, as measured by the elasticity of labor supply facing the requester (employer). We isolate plausibly exogenous variation in rewards using a double machine learning estimator applied to a large dataset of scraped MTurk tasks. We also reanalyze data from five MTurk experiments that randomized payments to obtain corresponding experimental estimates. Both approaches yield uniformly low labor supply elasticities, around 0.1, with little heterogeneity. Our results suggest monopsony might also be present even in putatively “thick” labor markets.

Fundamental limitations of dispersion mitigation filters
Authors: Granot Er’el
Published: February 2020

We investigate the fundamental limitations of dispersion mitigation filters. By analyzing the dispersion compensating process from basic principles, we demonstrate how a digital filter can mitigate arbitrarily weak dispersion without oversampling. We calculate the maximum distance the signal can pass with and without dispersion compensation, beyond which no data decoding is possible. Furthermore, we show the exact mathematical relation between this maximum distance and the length of the compensating filter – with and without a Forward Error Correction (FEC).
Robust silicon arbitrary ratio power splitters using shortcuts to adiabaticity
Authors: Chung Hung-Ching , Wang Tai-Chun , Hung Yung-Jr , Tseng Shuo-Yen
Published: February 2020

We design and fabricate a series of broadband silicon arbitrary power splitters with various split ratios using shortcuts to adiabaticity. In this approach, the system evolution is designed using the decoupled system states, and the desired split ratios are guaranteed by the boundary conditions. Furthermore, the system evolutions are optimized to be as close to the adiabatic states as possible, thus enhancing the robustness to wavelength and fabrication variations. The devices are more compact then the conventional adiabatic designs. Fabricated devices show broadband response for a wide wavelength range from 1.47 to 1.62 µm and also have excellent robustness against fabrication errors across an 8-inch wafer.
Scalable coarse integral holographic video display with integrated spatial image tiling
Authors: Li Jin , Smithwick Quinn , Chu Daping
Published: February 2020

The dynamic Coarse Integral Holography (CIH) display demonstrated previously can scan the low space bandwidth product (SBP) holographic images delivered by a high bandwidth spatial light modulator (SLM) to form a hologram array for angular tiling of the 3D images for a large field-of-view but only a modest size despite the utilization of the full bandwidth of the SLM in use. In this paper, we propose a scalable approach using seamless spatial tiling of the full bandwidth images generated by two high bandwidth SLMs using a resonant scanner and a high performance galvanometric scanner for a scalable CIH display capable of achieving twice of the final image size and doubled horizontal field-of-view (FOV). A proof-of-concept system is demonstrated with integrated full-parallax holographic 3D images. The proposed method has the potential to tile images generated by more than two SLMs for scalable large size and wide FOV holographic displays.
Ultra-narrow-linewidth measurement utilizing dual-parameter acquisition through a partially coherent light interference
Authors: Wang Zhihui , Ke Changjian , Zhong Yibo , Xing Chen , Wang Haoyu , Yang Keyuan , Cui Sheng , Liu Deming
Published: February 2020

Laser linewidths of the order of 100 Hz are challenging to measure with existing technology. We propose a simple, efficient method to measure ultra-narrow linewidths using dual-parameter acquisition based on partially coherent light interference. The linewidth is obtained using two parameters that are easily extracted from the power spectrum. This method reduces the influence of 1/f noise by utilizing a kilometer-order-length delay fiber and is independent of the fiber-length error for a general situation. Simulation results show that, for a length error less than 10%, the total linewidth measurement error is less than 0.3%. Experimental results confirm the feasibility and superior performance of this method.

Wirtschaftsinformatik-Forschung für die Praxis
Authors: Robra-Bissantz Susanne , Strahringer Susanne
Published: February 2020

Ganz im Sinne der Zeitschrift HMD – Praxis der Wirtschaftsinformatik existiert in Deutschland neben anderen Ausrichtungen auch eine explizit auf Praxisorientierung ausgerichtete Wirtschaftsinformatikforschung. Dieser Beitrag behandelt aus verschiedenen Blickwinkeln deren Entwicklungen und Strömungen. Im Mittelpunkt stehen Forschungsmethoden, die Forschung für die Praxis unterstützen. Dies sind insbesondere Methoden der Fallstudienforschung, der Aktionsforschung und der gestaltungsorientierten Forschung in verschiedenen Ausprägungen. Insbesondere diejenigen Methoden, die Forschung gemeinsam mit der Praxis anstreben, benötigen Rahmenbedingungen, die dies ermöglichen. Die gängigsten Kollaborationsformen, ihre Verknüpfung zu Forschungsmethoden, die von den jeweiligen Partnern zu erwartenden Nutzeffekte und Ergebnisse bilden den zweiten Schwerpunkt des Beitrages. Darüber hinaus identifizieren wir weitere Ansatzpunkte, die Forschern Wege aufzeigen, wie die Praxisrelevanz ihrer Forschung gesteigert werden kann. So gibt es methodische Bausteine, die vorhandene Forschungsmethoden um nicht invasive Komponenten ergänzen können, um die Relevanz der Forschungsergebnisse für die Praxis sicherzustellen. Zudem können Forscher auch an der besseren Konsumierbarkeit ihrer Ergebnisse arbeiten und sollten Mut fassen, die üblichen Routinen vergangener Forschung gelegentlich auch zu verlassen.
Werner Herzog’s Burgeoning Voice in The Great Ecstasy of the Woodcarver Steiner
Authors: Corbett Jack
Published: February 2020

At forty-three minutes long, The Great Ecstasy of the Woodcarver Steiner (1974) narrowly fulfills the forty-minute requirement of feature length. This duration places the film as Werner Herzog’s third feature-length documentary out of the current total of twenty-eight. The film was initially aired on television in West Germany as part of an hour-long episodic sports series. It follows Walter Steiner, the world champion ski jumper, as he practices for and then participates in a competition in Yugoslavia. Visually, the film unfolds on the steep, snowy slopes. The narrative, however, is created from three voices: Steiner himself, Herzog’s voice-over, and finally, at the mandate of the West German Television Station, Herzog as an on-camera reporter (Cronin 117). In the film, he waits at the slope of the mountain to see how Steiner’s jump unfolds, but the Herzog in the studio already knows the result. The shift of forcing an additional voice has pushed the comparably omniscient voice-over further into the subjective mode so there can be a differentiation between the two different voices.

The Wexner Center for the Arts showcased thirteen films over six days during its 5th annual Cinema Revival: A Festival of Film Restoration. These films ranged over a variety of genres and featured world-renowned directors and actors. The films featured over the weekend have origins that stretch the globe. From Argentina to Italy, the festival programming allowed viewers to get a glimpse into the history of world cinema, while the speakers introduced the films and shared not only their knowledge but also the detailed steps required for each film’s restoration. Although some films received more attendance than others, the festival was successful in its goal of sharing classic cinema with a modern audience and providing an even mix of technical discussion, background information, and entertainment.
Sundance Documentary Shorts Program 1 Review
Authors: Wright Quinn
Published: February 2020

2019’s Sundance Film Festival took place from January 23 to February 3 in Park City, Utah, as always. I attended for the third time, and while there, I caught a screening of Documentary Shorts Program 1 on Friday, January 25.

Overall, I found this well-curated program to feature high-quality shorts – even those with which I found issues were still entertaining and interesting.
La Junta de Cultura Vasca y la redacción de un catálogo monumental para Bizkaia (1917-1936)
Authors: Díez Paton Eva
Published: February 2020

Los catálogos monumentales deben considerarse instrumentos clave para la definición de las políticas de conservación patrimonial de las instituciones. La Junta de Cultura Vasca, dependiente de la Diputación de Bizkaia, estaba llamada a gestionar la política en torno a la conservación y restauración monumental. En el presente artículo se analizan los malogrados proyectos de la Junta de Cultura Vasca para la redacción de un catálogo monumental para Bizkaia.

Tú a Harvard y yo a Princenton. De la depresión a la esquizofrenia
Authors: Ruíz Martínez Mª Adolfina , Peralta Galisteo Sebastián , Castán Urbano Herminia
Published: February 2020

Hasta hace poco tiempo las enfermedades mentales eran tratadas como un todo, sin diferenciación alguna; las investigaciones realizadas en estos últimos años han resaltado las diferencias existentes entre algunas de ellas, de tal forma que hoy en día existen tratamientos específicos para las patologías descritas. El objetivo principal de este trabajo, es el de mostrar dos enfermedades diferentes pero que en muchos casos se confunden, depresión y esquizofrenia. Patologías que pueden tener como desencadenantes, situaciones muy diversas y que requieren un tratamiento farmacológico diferente. Para ello, se realizará un análisis de dos películas, Prozac Nation (2001) de Erik Skjoldbjaerg y Una mente maravillosa (2001) de Ron Howard que reflejan las vivencias reales de dos personajes; se analizará la sociedad en la que conviven y el entorno que les rodea, pero resaltando muy especialmente el apartado de la farmacoterapia, que medicamentos se utilizan, si es correcto su uso, los efectos adversos que presentan… para de esta forma poder prever si la visión de la película tiene carácter formativo en este tipo de temática.

Research results show that poor glycemic control and recurrent episodes of severe hypoglycaemia are associated with a decrease in cognitive function in elderly people with type 2 diabetes mellitus (T2DM). On the other hand, patients with diabetes mellitus associated with cognitive impairment/dementia are most at risk of developing hypoglycaemic conditions. It is obvious that the relationship between hypoglycaemia and dementia is very complex and has a mutually aggravating nature.
Studies also show that individuals of older age groups with diabetes and cognitive impairment have a high risk of developing hypoglycaemic conditions, such as unwanted side effects from glucose-lowering therapy. In this case, of particular interest is the question that is being actively studied at the present time, which is concerning the effect of different groups of glucose-lowering antidiabetic drugs on the cognitive status and the rate of cognitive decline in diabetic patients with cognitive impairment.
In this review, we attempted to summarise, systematise, and present data available in the literature concerning the effect of hypoglycaemia on the risk of cognitive impairment and dementia in elderly and senile patients with type-2 diabetes, as well as the degree of participation in this process of of various groups of sugar-lowering antidiabetic drugs.

BACKGROUND: Patients with any form of diabetes during pregnancy should achieve the target (close to physiological) values of glycaemia, the main condition for a safe course and outcomes of pregnancy. To accomplish this task, effective and safe methods of insulin therapy should be selected.
AIM: To determine the glycaemic profile and pregnancy outcomes in women with type 1 diabetes treated with continuous subcutaneous insulin infusion (CSII) and multiple insulin injections (MII).
METHODS: A continuous glucose monitoring (CGM) of 100 pregnant women with type 1 diabetes treated with CSII and 100 women treated with MII was conducted to assess the effectiveness of these insulin therapy regimens in achieving target blood glucose values.
RESULTS: HbA1c levels were significantly lower during the first, second, and third trimesters in patients treated with CSII than those treated with MII. Glucose variability has already improved since the second trimester of pregnancy in women treated with CSII, which was not observed in those treated with MII. The period of hyperglycaemia according to the results in pregnant women treated with CSII was 25 [13; 38] %, which was lower than those treated with MII, 41 [18; 54] %. No risk of obstetric and perinatal complications was observed with the duration of the hyperglycaemic state of 25% of the CGM time, whereas the risk of neonatal hypoglycaemia appeared with the duration of the hypoglycaemic state of a mother with type 1 diabetes of 0.2%. The relationship between glucose variability in terms of MAGE and MODD and the risk of developing macrosomia has been observed, and the dependence of glucose variability (MODD and CONGA) and the risk of neonatal hypoglycaemia and preeclampsia have also been confirmed.
CONCLUSION: Comprehensive assessment of the glycaemic profile when using CSII, confirmed the advantages of using CSII in pregnant women with type 1 diabetes to achieve the target glycaemia values, to reduce glucose variability and duration of hypoglycaemic episodes, which led to decreased frequency of obstetric and perinatal complications.
Scientometric Profile of Biochemistry Research in India a Study Based on Web of Science
Authors: K.G. Sudhier , V Dileepkumar
Published: February 2020

The paper examines 25,132 biochemistry research contributions of Indian scientists covered in the Web of Science for a period of 10 years (2004-2013). It was found that the biochemistry research is gradually growing and average annual growth rate was 36.84 per cent. The solo research was not prevalent and team research is more in the Indian biochemistry research and 97.46 per cent publications were contributed by multi- authors. It was observed that the value of co- authorship index was generally increasing and it varied from 93 to 105 during the period of study. Journal articles contribute 89.43 per cent of the total output followed by reviews (7.14 %). Indian researchers collaborate largely with the researchers of USA (2.49 %). The geographical distribution shows that Tamil Nadu, Uttar Pradesh and Delhi lead the list. The study shows that, C. Abdul Jaleel (58) and L. Pai (37) are the top ranked authors in the field. ‘Plos One’ is the top ranked journal and it published 296 papers during the study period. Academic institutions contribute more number of papers (50.26 %) followed by research institutions (28.24 %). The Lotka’s law was not found fit with the observed author productivity distribution of Indian biochemistry research.
Ważyk – Ford – Starski. Historia pewnego scenariusza
Authors: Małgorzata Hendrykowska Małgorzata Hendrykowska
Published: February 2020

The article presents the complicated story of a script, originally titled “ID Card”, was written in mid-1948 by Adam Ważyk. Had the script been approved for production, it would have been one of the first Polish post-war feature films. However, this did not happen. Apart from Adam Ważyk, Aleksander Ford, Jan Fethke and Ludwik Starski also worked on subsequent versions of the script. Due to complex political circumstances, none of the versions presented was approved by decision-makers. The author presents subsequent versions of the script which change along with social and political changes in Poland. The last version entitled “False Papers”, written by Ludwik Starski in 1968, contains clear elements of an action film. However, this was not a good time for this type of production. Over a period of 20 years, the script of “False Papers” underwent a peculiar metamorphosis: from a political pamphlet, to a didactic story, and finally, an action film with an unexplained mystery and war in the background. None of these versions became a film.
tragedy tailored to the spirit of the times – Romeo and Juliet as interpreted by Franco Zeffirelli and Baz Luhrmann
Authors: Śliwińska Anna
Published: February 2020

This article discusses two film adaptations of Romeo and Juliet, i.e. one directed by Franco Zeffirelli and the other by Baz Luhrmann. It covers the following aspects: the structure of both the drama and its two film adaptations, the characters’ creation, the choice of setting and screen time, and the function of tragedy. Shakespeare’s language is characterised by unparalleled wit and powers of observation, and the final form of his plays is a clear indication of his ambivalent attitude towards tradition and the rigid structure of the drama. By breaking with convention, favouring an episodic structure, and blending tragedy with comedy, Shakespeare always takes risks, in a similar vain to the two directors who decided to make film adaptations based on his plays. Each technical device the adaptors selected could have turned out to be a wonderful novelty or a total disaster. The strength of both Zeffirelli’s and Luhrman’s adaptations is their emphasis on love and youth, which thanks to their directorial skill is perfectly in tune with the spirit of their respective times.
Grecka terminologia łowiecka w świetle tekstów prawnych
Authors: Gortych-Michalak Karolina
Published: February 2020

W niniejszym artykule zaprezentowano terminologię łowiecką, jaka jest obecna tak we współczesnym, standardowym języku nowogreckim, jak i w greckich oraz cypryjskich aktach normatywnych regulujących praktykowanie łowiectwa w tych państwach. Język łowiecki istniejący w języku standardowym oraz język prawny są językami specjalistycznymi, służącymi realizacji specyficznych zadań (LSP) i obydwa zawierają terminologie właściwą łowiectwu. Terminologia, właśnie, jest kryterium, które odróżnia język specjalistyczny w sposób najbardziej znaczący od języka ogólnego. Mimo tego elementu wspólnego zarówno język łowiecki, jak i język prawmy regulujący kwestie łowieckie nie są sobie równe i nie mogą funkcjonować w do realizacji tych samych celów7, stąd niemożność ich połączenia w jeden zbiór, ponieważ ten sam termin może mieć inne znaczenie w każdym z tych języków. Celem artykułu jest zbadanie i zaprezentowanie różnic w zakresie terminologii w języku łowieckim o raz w języku prawnym łowieckim (regulującym łowiectwo) w oparciu o materiały specjalistyczne na temat łowiectwa oraz teksty 7 aktów normatywnych regulujących łowiectwo w Grecji i na Cyprze.
