Authors: Clarke D.L. , Brysiewicz P. , Sartorius B. , Bruce J.L. , Laing G.L.
Published: March 2017

Introduction:

This study used data from a prospectively maintained trauma database to assess the level of systolic blood pressure at which mortality rates for trauma begin to increase and to compare systolic blood pressure with base deficit as a predictor of outcome.

Methodology:

The Pietermaritzburg Metropolitan Trauma Service maintains a prospective digital trauma registry. All trauma patients admitted to the service for the period January 2012–January 2015 were included. Analysis was performed on systolic blood pressure relative to a number of selected markers of outcome and a variety of physiological parameters.

Results:

Out of an original data set of 2974 trauma patients, a total of 169 elective patients, 799 patients with isolated traumatic brain injury, and 27 patients with incomplete data were excluded to leave a sample size of 2148 patients. Of these, 1830 (85.2%) were males and 318 (14.8%) were females. The mean age (standard deviation) was 31.8 (12.0) years. The median age (interquartile range) was 29 (23–37) years. There were 89 deaths in this cohort (4.1%). The median systolic blood pressure (interquartile range) was 123 (112–136) mmHg. The median base deficit was −1.4 (interquartile range: −4.5 to 1). The inflection curves below with fitted non-linear curve clearly show the upward change in mortality frequency around a systolic blood pressure of ⩽110 mmHg as well for a base deficit below −5. A cutoff of <110 for systolic blood pressure yields a high sensitivity and very high positive predictive value of 82% (95% confidence interval: 81–84) and 98% (95% confidence interval: 97–98), but low specificity (56%) and negative predictive value (12%), respectively. Similar optimal cutoff analysis for base deficit versus mortality suggests base deficit >4.8 as a good predictor area under the curve (0.82; 95% confidence interval: 0.75–0.88). This cutoff yields a high sensitivity of 80% (95% confidence interval: 78–82), moderate specificity of 75% (95% confidence interval: 62–85), very high positive predictive value of 98% (95% confidence interval: 97–99) but low negative predictive value of 17% (15–28).

Conclusion:

The data suggest that traumatic shock starts to become manifest at a systolic blood pressure of 110 mmHg and that a systolic blood pressure reading of 90 mmHg represents an advanced state of shock. Systolic blood pressure by itself is a poor predictor of mortality and outcome. Base deficit appears to be a far better predictor of mortality than systolic blood pressure. Future models to categorize shock will have to combine vital signs with biochemical markers of hypoperfusion.

Authors: Mäntymäki H. , Junnila M. , Lankinen P. , Seppänen M. , Vahlberg T. , Mäkelä K. T.
Published: March 2017

Background and Aims:

An adverse reaction to metal debris is a known complication after large diameter head metal-on-metal total hip arthroplasty. However, the failure rate varies depending on the implant design. Therefore, we investigated the prevalence of adverse reaction to metal debris, as well as the symptoms and risk factors after undergoing a ReCap-M2a-Magnum large diameter head metal-on-metal total hip arthroplasty.

Materials and Methods:

Between 2005 and 2012, 1188 patients (1329 hips) underwent ReCap-M2a-Magnum total hip arthroplasty at our institution. Systematic screening for adverse reaction to metal debris was arranged using the Oxford Hip Score questionnaire, hip and pelvic radiographs, and assessments of the serum chromium and cobalt ion levels. Clinical evaluation and magnetic resonance imaging were performed for the symptomatic patients, as well as those with either chromium or cobalt ion levels ⩾5 µg/L. The prevalence of adverse reaction to metal debris after ReCap-M2a-Magnum total hip arthroplasty was assessed, and the risk factors for adverse reaction to metal debris were evaluated using logistic regression. The mean follow-up time was 5.2 (0.003–9.1) years. This study was an extension of a previous study conducted at our institution with 80 patients.

Results:

In total, 33 patients (33 hips, 2.5% of all hips) required a revision operation due to adverse reaction to metal debris. Moreover, 157 hips exhibited definitive adverse reaction to metal debris, but a revision operation was not performed (157 of 1329 hips, 11.8% of all hips). Overall, 190 out of 1329 (14.3%) hips had definitive adverse reaction to metal debris. Pain, subluxation sensation, clicking, swelling, a small head size, and a fair/poor Oxford Hip Score were associated with definitive adverse reaction to metal debris.

Conclusion:

We found a high prevalence of adverse reaction to metal debris in the ReCap-M2a-Magnum total hip arthroplasty patients in this study; however, most of the patients did not require revision operations.
Preoperative Aspartate Aminotransferase-to-Platelet Ratio Index Predicts Perioperative Liver-Related Complications Following Liver Resection for Colorectal Cancer Metastases
Authors: Amptoulach S. , Gross G. , Sturesson C. , Rissler P. , Kalaitzakis E.
Published: March 2017

Background and Aims:

There are limited data on the potential role of preoperative non-invasive markers, specifically the aspartate-to-alanine aminotransferase ratio and the aspartate aminotransferase-to-platelet ratio index, in predicting perioperative liver-related complications after hepatectomy for colorectal cancer metastases.

Methods:

Patients undergoing liver resection for colorectal cancer metastases in a European institution during 2003–2010 were retrospectively enrolled. Relevant data, such as neoadjuvant chemotherapy, preoperative liver function tests, and perioperative complications, were collected from medical records. The nontumorous liver parenchyma in the surgical specimens of 31 patients was re-evaluated.

Results:

Overall, 215 patients were included. In total, 40% underwent neoadjuvant chemotherapy and 47% major resection, while 47% had perioperative complications (6% liver-related). In multivariate regression analysis, the aspartate aminotransferase-to-platelet ratio index was independently associated with liver-related complications (odds ratio: 1.149, p = 0.003) and perioperative liver failure (odds ratio: 1.155, p = 0.012). The latter was also true in the subcohort of patients with neoadjuvant chemotherapy (odds ratio: 1.157, p = 0.004) but not in those without such therapy (p = 0.062). The aspartate-to-alanine aminotransferase ratio was not related to liver-related complications (p = 0.929). The area under the receiver operating characteristics curve for the aspartate aminotransferase-to-platelet ratio index as a predictor of liver-related complications was 0.857 (p = 0.008) in patients with neoadjuvant chemotherapy. Increasing aspartate aminotransferase-to-platelet ratio index was observed with an increase in degrees of sinusoidal obstruction syndrome (p = 0.01) but not for fibrosis (p = 0.175) or steatosis (p = 0.173) in the nontumorous liver in surgical specimens.

Conclusion:

The preoperative aspartate aminotransferase-to-platelet ratio index, but not the aspartate-to-alanine aminotransferase ratio, predicts perioperative liver-related complications following hepatectomy due to colorectal cancer metastases, in particular after neoadjuvant chemotherapy. The aspartate aminotransferase-to-platelet ratio index is related to sinusoidal obstruction syndrome in the nontumorous liver.

Background:

The long waiting time in our General Pediatric Clinic results in the delay in diagnosis and treatment leading to increase in morbidity and dissatisfaction rate among sick children who seek treatment at KK Women’s and Children’s Hospital, Singapore. The mean ± SD waiting time in our General Pediatric Clinic increased from 40 ± 4 days in 2008 and 45 ± 7 days in 2009 to 50 ± 5 days in 2010.

Objectives:

To reduce long waiting times in our General Pediatric Clinic by 20%.

Methods:

The Reducing Waiting Time Working Group was formed to tackle the waiting time problem in the General Pediatric Clinic. Extensive literature was searched and reviewed, brainstorming and discussions were carried out and strategies were developed. A series of implementations were carried out sequentially including clearing of the backlog of cases, development of general and fast track referral guidelines, triaging system and ‘5 Days SMS and 48 Hours Call’ system.

Results:

By clearing the backlog cases, waiting time was reduced from 57 days to 44 days. Through effective triaging system and ‘5 Days SMS and 48 Hours Call’ system, the mean ± SD waiting time was further reduced by 30% from 50 ± 5 days to 35 ± 7 days. By June 2012, the mean waiting time was 27 days.

Conclusions:

Waiting time is one of the important indicators of healthcare quality provided by any healthcare institution. Through these implementations, waiting time was successfully reduced by 30%. These methods may serve as viable options to improve waiting time in other healthcare settings.
Total Kidney Volume as a Biomarker of Disease Progression in Autosomal Dominant Polycystic Kidney Disease
Authors: Tangri Navdeep , Hougen Ingrid , Alam Ahsan , Perrone Ronald , McFarlane Phil , Pei York
Published: March 2017

Purpose of review:

Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disorder characterized by the formation of kidney cysts and kidney enlargement, which progresses to kidney failure by the fifth to seventh decade of life in a majority of patients. Disease progression is evaluated primarily through serum creatinine and estimated glomerular filtration rate (eGFR) measurements; however, it is known that serum creatinine and eGFR values typically do not change until the fourth or fifth decade of life. Until recently, therapy only existed to target complications of ADPKD. As therapeutic agents continue to be investigated for use in ADPKD, a suitable biomarker of disease progression in place of serum creatinine is needed.

Sources of information:

This review summarizes recent research regarding the use of total kidney volume as a biomarker in ADPKD, as presented at the Canadian Society of Nephrology symposium held in April 2015.

Findings:

Measurement of patients’ total kidney volume made using ultrasound (US) or magnetic resonance imaging (MRI) has been shown by the Consortium for Radiologic Imaging Studies of Polycystic Kidney Disease (CRISP) study to be directly correlated with both increases in cyst volume and change in glomerular filtration rate (GFR). Additional studies have shown total kidney volume to have an association with complications of ADPKD as well.

Limitations:

Areas for further study continue to exist in comparison of methods of measuring total kidney volume.

Implications:

We believe that the evidence suggests that total kidney volume may be an appropriate surrogate marker for ADPKD disease progression.
Does Context Matter? A Multi-Method Assessment of Affect in Adolescent Depression Across Multiple Affective Interaction Contexts
Authors: Nelson Benjamin W. , Byrne Michelle L. , Sheeber Lisa , Allen Nicholas B.
Published: March 2017

This study utilized a multimethod approach (self-reported affect, observed behavior, and psychophysiology) to investigate differences between clinically depressed and nondepressed adolescents across three different affective interaction contexts with their parents. A total of 152 adolescents (52 males, 14–18 years old), and their parents, participated in a laboratory session in which they discussed positive and negative aspects of their relationship and reminisced on positive and negative memories. We found that across contexts depressed adolescents exhibited higher negative affect and behaviors, lower positive behaviors, and greater autonomic and sympathetic activity. Context-specific findings indicated that (a) depressed adolescents exhibited greater persistence of negative affect and dysphoric behavior across the sequence of tasks, whereas these phenomena declined among their nondepressed peers; (b) depressed adolescents had greater increases in aggressive behaviors during negative interactions; and (c) depressed adolescents had greater parasympathetic withdrawal during negative interactions, whereas this response characterized the nondepressed group during positive interactions.
Introduction to this special section: Data analytics and machine learning
Authors: Davidson Mike
Published: March 2017

The explosion of data types and volumes we are experiencing in the oil field, particularly in unconventional reservoir development, is stretching the capabilities of traditional manual workflows. The complex interactions between dynamic reservoir properties and the many-faceted well completions process are governed by complex physics that may be only partially understood. Furthermore, our best attempts to perform controlled experiments can often produce highly varied results, suggesting the stochastic nature of production from unconventionals and that we may benefit from adding new tools to our toolkit of deterministic, physics-based analysis.

Published: March 2017

Objective:

To evaluate treatment outcomes and patterns of CT lung injury after hypofractionated image-guided radiotherapy delivered with helical tomotherapy (HHT) in a series of inoperable lung lesions.

Methods:

68 patients who were medically inoperable (69 lesions) without evidence of viable extrathoracic disease were included. Dose prescription was driven by tumour location (hilar/pericentral vs peripheral) and/or target volume. 52% of the lesions received a biological equivalent dose (BED10) ≥100 Gy. Assessment of tumour response was based on the Response Evaluation Criteria in Solid Tumours 1.1 criteria coupled with fluorine-18 fludeoxyglucose/positron emission tomography-CT. Toxicity monitoring was focused on treatment-related pulmonary adverse events according to the Common Terminology Criteria for Adverse Events v. 4.0. Acute and late events were classified as radiation pneumonitis (RP) and radiation fibrosis (RF), respectively. Survival curves were calculated using the Kaplan–Meier method. Univariate and multivariate analyses of survival were performed using the Cox proportional hazards model.

Results:

After a median follow-up of 12 months (range, 3–31 months), no instances of ≥Grade 4 RP was documented, and clinically severe (Grade 3) RP occurred in 5.8% of the patients. 2 (3%) patients developed a late severe (≥Grade 3) symptomatic RF. No specific pattern of CT lung injury was demonstrated, in both acute and late settings. Median overall survival (OS) and progression-free survival (PFS) for the entire population were 30.8 and 14.1 months, respectively. At multivariate analysis (MVA), BED10 ≥ 100 Gy and KPS ≥ 90 emerged as significant prognostic factors for OS (p = 0.01 and p = 0.001, respectively), and BED10 ≥ 100 Gy for PFS (p = 0.02).

Conclusion:

Our findings show that HHT adjusted for tumour location and/or target volume is an effective treatment with an acceptable toxicity profile in patients who are medically inoperable with lung tumours and is not associated with a specific pattern of lung injury. Therefore, it can represent a viable option when conventional stereotactic ablative radiotherapy facilities are not available.

Advances in knowledge:

The present study is among the largest series addressing the role of HHT for inoperable lung tumours. This technique is safe and effective and is not associated with a specific pattern of lung injury, at least at early and average time points.

Modern methods of chemical-thermal treatment (CTT) such as cyanidation, nitrogen casehardening and others are widelyused in different branches of industry and they are processes promising enough. The solution of ecological problems of diffusion strengthening and improvement of performance attributes of a surface layer are interrelated with the use of special powder mixtures – lutes, pastes, called saturating environment (carburizer). As a saturating environment in the work there is used a nitrogen-carbon paste on the basis of fine gas black (amorphous carbon ~ 60%) and iron sinergisty potassium ~ 40% with the addition of carbamide (urea) as a nitrogen-containing component. A saturating pasty environment on the basis of soot with nitrogen-containing admixtures (urea and iron sinergisty potassium) is efficient for the surface strengthening treatment of steel products in a wide range of temperatures. Solid carbonitrides arising on the surface of products processed in this environment promote the increase of their wear-resistance and other performance attributes. A carbonitride edge on the surface of steel (20…30) ChGT arising at nitrogen case-hardening in a paste-type carburizer does not decrease wear-resistance, but, at the same time increases working capacity of parts and units and material fatigue resistance.

The paper reports the expediency and substantiation of the necessity for the gradual transition to power units on supercritical stream parameters in world power engineering. Basic stages in the development of steam turbine manufacturing with supercritical steam parameters are considered. The parameter increase at the input makes a profound impact upon the design of a flowing part of turbines. To operate a great difference in enthalpies in a cylinder without changing stages number one has to modernize them and sometimes to change the design completely. In the paper there is considered the expediency of the application of axial highloaded stages developed by the Polytechnics of Leningrad (LPI). There are also described the stages of designing steam turbine plants with critical and supercritical steam parameters at the input in a turbine. As an example there is analyzed SKR-100-300 steam turbine with the initial steam parameters of 29.4MPa and 650S. The results of solution computations directed to the efficiency increase of a regulatory stage of K-300-240 steam turbine with supercritical parameters of 580C and 29.0 MPa are presented. The application as a profile of an impeller the blade design of LPI allows increasing turbine plant efficiency in a wide range of mode parameters and also reducing a general number of turbine stages.

The investigations carried out deal with the re-gularity study in the distribution of shock pulse energy at multiple procedures of loading. The experimental researches were carried out on the specially developed test bench in which under all waveguides (or tools) of the shock system there were situated independently (separately) sensors connected with an oscilloscope registering parameters of a shock pulse (a form, amplitude, duration).

As a result it was determined that the increase of the eccentricity in the symmetry axis location of a head and a waveguide (or a tool) and their number in the shock system contributes to the reduction of an energy portion sent to the deformation source. The application of multi-contact schemes of loading allows sending large total energy of a shock pulse to the deformation source to accept conditions of experiment fulfillment.

At that the energy portion of a shock pulse fall-ing to each waveguide (or a tool) in the multicontact scheme as compared with the singlecontact one decreases (for rod-formed waveguides by 20%, and for spherical tools – by 15%) at the installation of each subsequent waveguide (or a tool) in the shock system.

Published: March 2017

A finite element procedure for calculated inves-tigations of SSS at a crack tip in a babbit layer is created. The procedure is adjusted for bimetal cylin-drical sample loaded according to a circuit of bending with rotation. The dependences for stress intensity factors are obtained and it is shown that accuracy of such modeling is higher than in procedure options used ear-lier. A set of computations for samples with some cracks in a layer is carried out. The criteria of crack separation into independent and interacted are revealed. The results of the work will be used for the further adjusted analysis of experiments and for the formation of dependences in a cyclic crack resistance of babbit layers. The procedure shown and results can be useful for other objects with layers applied on a more solid basis.

Authors: Santos Carolina Mundim de Souza Marques dos , Siqueira Eduardo Queija de , Ariza Bernardo Guedes
Published: March 2017

Sedimentos urbanos são potencialmente poluidores devido sua capacidade de associação a poluentes como metais pesados, aumentando a possibilidade de contaminação de corpos d’água em ambiente urbano. Devido à pouca quantidade de estudos relacionados aos sedimentos urbanos, este artigo visa analisar a granulometria, a fração orgânica e inorgânica e quantificar a carga e o acúmulo de sedimentos, verificando sua relação com o fluxo de veículos e a ocorrência de precipitação. Para tal, foram selecionadas três ruas com diferentes fluxos de veículos, onde foram coletados sedimentos nas sarjetas pelo método da escovação e aspiração. Também foram analisados os sedimentos contidos nos filtros de um amostrador de partículas de grande volume localizado em uma das áreas estudadas. Foram realizadas análises granulométricas por difratometria a laser, e a carga e o acúmulo foram determinados por pesagem em balança analítica de precisão e avaliados temporalmente. Os resultados mostram que a carga de sedimentos tem uma relação inversa com a ocorrência/intensidade de precipitação e com o fluxo de veículos. Quanto à fração orgânica e inorgânica, foi possível verificar que a via com maior presença de arborização apresentou maior fração orgânica, e que os sedimentos das vias apresentam, de modo geral, maior fração orgânica que os sedimentos de solo natural. O diâmetro médio das partículas apresentou uma tendência de aumento com a ocorrência de chuvas, e uma relação direta com o fluxo de veículos, onde a via com fluxo maior apresentou as maiores granulometrias.

Published: March 2017

The manager-employee communication is the basis of an effective management. Communication is sort of an executive skill. In this research, the aim is to determine how this skill affects the levels of job satisfaction and job commitment and whether there is a relationship between these concepts. The research was conducted by means of relational screening model and survey method was used in order to collect data. "Managerial communication skills scale" developed by Tanrıverdi and colleagues (2010) for health administrators was used in evaluating managerial communication skills. In the evaluation of job satisfaction of the employees was used 5 items that measure job satisfaction developed by Brown and Peterson (1994). The sample of the study consisted of 399 people, of which 180 were female (45.1%) and 219 were male (54.9%), determined by random sampling method. The obtained data were analyzed by frequency analysis, T-test, cross table, simple and multiple regression models using SPSS 20.0 package program. Analyses have shown that there is a positive, bi-directional and moderate relationship between managerial communication skills and job satisfaction and job commitment levels; positive, bi-directional but weak relationship between job satisfaction and job commitment. According to the regression model developed according to research hypotheses, it is understood that managerial communication skills are effective in the level of job satisfaction and job commitment of employees. Analyses confirm all of the hypotheses. It has been proposed to increase the frequency and level of training given for the development of communication skills of managers.

The novels are arranged chronologically and divided into two parts: censored ones and those published without official approval and censorship. The first group includes Jeszcze miłość by Bogusław Kogut, Odyseja, odyseja by Marian Grześczak and Wióry by Krystyna Kofta. The second group includes Krótki żywot bohatera pozytywnego by Piotr Guzy, Ciemnia by Bogusława Latawiec, Krew by Andrzej Górny, and Węzeł by Józef Ratajczak. The first group, true to the course of history, represent the rise of the political thaw and the party regaining control over situation. The second group, because of the time of writing, cover a longer time and tend to universalize the theme. In novelistic representations of Poznań 1956 protests there are two strains: uprising-themed and strike-themed. It turns out that the latter is the least present, because most novelistic characters are party-members and intelligentsia, whereas workers and ordinary people are relegated to the background. Plotlines are arranged biographically, not chronologically, because the novels are narrated as internal monologues with retrospective memories. The novels written by authors from Poznań, or related to Poznań, focus on the provintial character of the city, as opposed to the centralist influence of Warsaw.
„Śmierć Romka” (poznański Czerwiec w prozie Janusza Krasińskiego)
Authors: Urbanowski Maciej
Published: March 2017

The article reconstructs and analyses the image of Poznań 1956 protests in the well known novel cycle by Janusz Krasiński. For the protagonist, Szymon Bolesta, the death of Romek Strzałkowski is particularly painful, an event extensively reconstructed in the conclusion of Niemoc , one of the novels. The execution of Romek and the propaganda lies about it, are for Bolesta the key examples of the criminal nature of the communist regime, and the Black Thursday he interprets as an unsuccessful national uprising.
Periodic Impact Motions at Resonance of a Particle Bouncing on Spheres and Cylinders
Authors: Sfecci Andrea
Published: March 2017

We investigate the existence of periodic trajectories of a particle, subject to a central force, which can hit a sphere or a cylinder. We will also provide a Landesman–Lazer-type condition in the case of a nonlinearity satisfying a double resonance condition. Afterwards, we will show how such a result can be adapted to obtain a new result for the impact oscillator at double resonance.
Two types of gabbroic xenoliths from rhyolite dominated Niijima volcano, northern part of Izu-Bonin arc: petrological and geochemical constraints

We examined the petrography, petrology, and geochemistry of two types of gabbroic xenoliths (A- and B-type xenoliths) in olivine basalt and biotite rhyolite units among the dominantly rhyolitic rocks in Niijima volcano, northern Izu-Bonin volcanic arc, central Japan. A-type gabbroic xenoliths consisting of plagioclase, clinopyroxene, and orthopyroxene with an adcumulate texture were found in both olivine basalt and biotite rhyolite units, and B-type gabbroic xenoliths consisting of plagioclase and amphibole with an orthocumulate texture were found only in biotite rhyolite units. Geothermal- and barometricmodelling based on mineral chemistry indicated that the A-type gabbro formed at higher temperatures (899–955°C) and pressures (3.6–5.9 kbar) than the B-type gabbro (687–824°C and 0.8–3.6 kbar). These findings and whole-rock chemistry suggest different parental magmas for the two types of gabbro. The A-type gabbro was likely formed from basaltic magma, whereas the B-type gabbro was likely formed from an intermediate (andesitic) magma. The gabbroic xenoliths in erupted products at Niijima volcano indicate the presence of mafic to intermediate cumulate bodies of different origins at relatively shallower levels beneath the dominantly rhyolitic volcano.
The NLRC4 inflammasome: The pieces of the puzzle are falling into place
Authors: Hafner-Bratkovič Iva
Published: March 2017

Inflammasomes are intracellular multiprotein platforms for the activation of inflammatory caspases. As components of the innate immune system, they play an important role in the fight against microbes. However, aberrant inflammasome activation has been implicated in auto-inflammatory syndromes. This review focuses on the NLRC4 inflammasome. This is perhaps not the most extensively studied, yet its mechanism of activation is by far the best understood. The NLRC4 inflammasome is activated by several proteins originating from intracellular bacteria, which are first sensed by receptors of the NAIP family. Activated NAIP binds NLRC4, which further recruits dormant NLRC4 molecules in a prion-like oligomerization event. NLRC4 enables a strong amplification of the signal, providing a fast and robust host response. The review also discusses peculiar NLRC4 inflammasome functions in promoting eicosanoid biosynthesis, actin reorganization, and its roles in autoinflammatory syndromes and sterile inflammation. Finally, the first inflammasome-independent engagement of NLRC4 in suppressing melanoma tumor growth is presented. The emerging roles of NLRC4 in various normal and pathological processes demonstrate that there is still plenty to be learned about the NLRC4 mechanism of activation and downstream functions.
Verbal number and transitivity in Karko (Kordofan Nubian)
Authors: Jakobi Angelika
Published: March 2017

The present paper is concerned with Karko, a Kordofan Nubian language of Sudan. The paper tries to show how verbal number formally interacts with the encoding of grammatical relations. Verbal number – as realized by singular stems and plural stems – is sensitive to the number of the intransitive subject, the number of the transitive object and the number of the direct object in a ditransitive clause. Moreover, the paper provides evidence of passive and anti-passive constructions being based on plural (rather than singular) verb stems. This suggests that plural verb stems are associated with reduced transitivity.
Pluractionals in Dagik
Authors: Vanderelst John
Published: March 2017

This chapter investigates pluractionals in Dagik, a Kordofanian language spoken in the Nuba Mountains in Sudan. There is a wealth of derivational means to build pluractionals: two verbal extensions, several types of partial stem reduplication and stem replacement. These derivational means can be combined with one another, suggesting that some of them are in the process of getting recycled. The core meaning of pluractionals is multiplicity of occurrence of the verbal process. The latter is either carried out by or onto several participants (distributive meaning), or carried out several times by one participant (iterative meaning). Additional readings (durative, telic and habitual) are available.
Adversary Voting in the Czech Chamber of Deputies (1993–2013)
Authors: Dvořák Petr
Published: March 2017

The paper explores the legislative unity of government and opposition blocs in the Czech Chamber of Deputies over a period of 20 years. As voting unity is usually rather low in the Czech Republic, temporarily high concentrations of votes by these blocs are linked to higher rates of conflict between the government and opposition. I use the Rice and UNITY indices to compare average unity scores of individual cabinets and also explorative time series of unity vectors in order to analyse bloc concentration, success rate, and increased conflict. The outcomes are relevant both as comprising a case study and methodological observations: (1) Broad differences in the logic of interaction are confirmed (e.g. caretaker cabinets show less conflict than standard cabinets). Although no universal trend (e.g. no transition from consensual to conflictual practice) is found, the Czech opposition became more concentrated and resorted to serial blocking tactics in the second decade; thus, a major change of behavior occurred after all. (2) The Rice and UNITY indices correlate considerably; UNITY’s discrimination capacity is not distorted significantly despite the nature of equilibria in the Chamber. Moreover; the UNITY index is able to easily distinguish contested votes not detectable by the Rice index alone.
Bridging and Conversation in International Relations
Authors: Busser Mark , Wegner Nicole
Published: March 2017

The community of scholars working in or around the field of international relations is increasingly splintered across multiple empirical, methodological and theoretical divides. Faced with increasing fracturing pressures, what steps can be taken to ensure that a genuine spirit of engagement is maintained? This paper explores the challenges of scholarly conversation in an increasingly complex academic environment in order to develop some strategies and techniques aimed at helping students and young scholars to engage productively with the multiple contestations which continue to shape the field. By encouraging the practice of working to build “bridging resources”, a diverse community of scholars can find ways to demystify terminological and conceptual barriers. Furthermore, a commitment to engaged forms of scholarly conversation can help to distil and re-articulate even the most ambiguous perpectival distinctions and points of contention in such a way that disagreements within the field can be more accurately understood and navigated, even if not overcome.

Ética e Estética do Kitsch: subsídios para o estudo do gosto popular na experiência contemporânea
Authors: Wajnman Solange
Published: March 2017

Para além do mau gosto, da ornamentação excessiva, da sentimentalidade desmesurada de algumas das camadas populares e dos falsos originais daqueles que concorrem rumo ao pódio artístico-social, o kitsch pode ser compreendido como uma “forma” dinâmica na experiência contemporânea. Argumentamos aqui a favor da construção de um instrumental teórico-metodológico comum a algumas das lógicas da estética popular e práticas artísticas e/ou tecnológicas atuais. Tal instrumental é proposto a partir da articulação de eixos conceituais derivados das lógicas do empilhamento, da heterogeneidade, da sedimentação, da transposição e do deslocamento e das noções de alegoria e bricolagem.
