Abstract
The following paper tries to bring Marx’s crisis theory up to date from a sociological and social-philosophy point of view. Crisis, in line with Marx and Kant, is interpreted as a negative sign of history. Marx’s crisis scenario, while founded in an ever pertinent critique of the destruction of egalitarian individualism by the capitalist system must be considered lacking in complexity for today’s world. Marx underestimated the historical role of the state. A revision of his crisis theory leads to a re-evaluation of the latest two large-scale historical attempts to deal with the crises of modern capitalism; the mixed economy of the Keynesian welfare state, the crisis of which prepared the field for the succeeding crisis, the preventive counterrevolution of neoliberalism. This counterrevolution has plunged democracy into a crisis with slim prospects of escape.
Grade Incentive to Boost Course Evaluation Response Rates

AbstractAbstract In most schools of nursing, students rate their satisfaction with courses and teachers at the end of the semester. Low response rates on these evaluations make it difficult to interpret the results. Students were incentivized to complete their course evaluations by adding 1–2 points to one test score in the course in exchange for 85 % or higher participation by the total cohort. Ongoing monitoring and communication to students by faculty during the process was critical to motivating students to complete course evaluations. When the incentive was employed, student participation ranged from a low of 90 % to a high of 100 % response rate. The added points did not change any of the students' grades. Incentivizing students to complete course evaluations is an effective strategy to boost response rates without changing final course grades.

Iuwers zornes unmâze / missevellet uns sêre – Legitimität von Maßlosigkeit im mittelalterlichen Erzählkosmos
Authors: Bendheim Amelie 
Published: June 2018

AbstractStarting from the deficiencies of current approaches regarding the description of the hero in medieval narratives, this article aims to functionalise exorbitance (unmâze) as a new category of literary history. Unlike the conceptual and binary typing of the protagonist as ‘hero’ resp. ‘knight’, this category promotes a flexible model that operates relationally and hence enables gradual differentiations between the texts.Examples of medieval (heroic) epic (‘Nibelungenlied’) and (chivalric) romance (‘Flore und Blanscheflur’, ‘Wigalois’) will show the narrative treatment and stylisation of the exorbitant hero. The focus will be on the varying assessments of his acts: If the epic hero is able to defy social norms and current laws (cf. Siegfried’s courtship, Hagen’s murdering of Siegfried) without being penalised, the exorbitance in the romance falls within the scope of ‘ratio’. Thus, exorbitance is on the one hand confined and ‘assessed’, on the other hand excessive acts are rigorously sanctioned and inhibited. Referring to the current manifestations of exorbitance in the socio-political context, the concept of exorbitance emerges as an unchanged productive pattern. Its socio-political relevance encourages a literary-historical, epoch-spanning use of this concept, whose scope is a re-assessment of the history of literature as the history of exorbitance.
Distribution of ascaridoid nematodes (Nematoda: Chromadorea: Ascaridoidea) in fish from the Barents Sea

Published: June 2018

Abstract
The Ascaridoidea are parasites with heteroxenous life cycles. The study shows that fish can be paratenic, intermediate, or final hosts for parasites, and parasitic fauna reflects the feeding behavior of the hosts. Each species of parasites has also different environmental preferences and host specificity. Parasitic nematodes of fish representing Pleuronectidae, Gadidae, Sebastidae, and Macrouridae were studied. Worms were collected separately from different infection sites: stomach, intestine, liver and body cavity. Nematodes were identified using both morphological and molecular methods (PCR-RFLP). Six nematode species were recorded: Anisakis simplex s.s., Contracaecum osculatum A, B, and C. osculatum C (s.s.), Hysterothylacium aduncum and Pseudoterranova bulbosa. Anisakis simplex s.s. was the most numerous nematode species of all catches combined. Differences in parasite species composition were related to the depth and location of sampling areas. In the fish from deep waters, the abundance of A. simplex s.s. decreased compared to fish from shallow waters and P. bulbosa was the dominant species. Ascaridoid species have specific preferences regarding the impact on various internal organs of fish, which is reflected in their abundance. The presence of Ascaridoidea in the Barents Sea is associated with the distribution of hosts and varying food preferences related to the age of fish. The abundance of parasites varied between different host species.
Reduction of nutrient emission from Polish territory into the Baltic Sea (1988–2014) confronted with real environmental needs and international requirements

Published: June 2018

Abstract
Eutrophication of the Baltic Sea is considered a major threat to its ecological status. We present and discuss Polish riverine flow normalized loads of total nitrogen (TN) and total phosphorus (TP) discharged into the Baltic Sea in (i)1988–2014, (ii) periods of maximum TN (1992–1994), TP (1988–1991) emission, (iii) the reference period (1997–2003) established by the Helsinki Commission (HELCOM), (iv) 2012–2014, last years of our study. Despite considerable nutrient load reductions prior to the HELCOM reference period, Poland is expected to reduce TN and TP loads by 30% and 66%, respectively. In the light of our historical and up-to-date findings defining ecological status of the Baltic Sea, we suggest that the proposed TP load reduction is overestimated and its realization may lead to (i) undesirable consequences for the Baltic ecosystem, (ii) would require a decline in TP concentrations to 0.067 mg P dm-3 (the Vistula River) and 0.083 mg P dm-3 (the Oder River), values reported for pre-industrial times. The current nutrient concentrations in the Vistula and Oder safely comply with the requirements of the Water Framework Directive. We also comment on the top-down and bottom-up effect resulting in quantitative and qualitative reorganization of the Baltic ecosystem, a phenomenon already observed in the Baltic Sea.
Diatom record of progressive anthropopressure in the Gulf of Gdańsk and the Vistula Lagoon
Authors: Witak Małgorzata , Pędziński Jarosław 
Published: June 2018

Abstract
This study describes the subfossil diatom flora in the surface sediments of the Polish coastal waters in relation to human impact. The material studied consists of the uppermost parts of seven sediment cores collected from the SW Gulf of Gdańsk and eight cores from the Vistula Lagoon. Our results show the present-day ecological state of both basins just before the planned construction of a navigable channel of the Vistula Spit, which will be the next factor affecting their hydrology. In different parts of the Gulf of Gdańsk, cultural eutrophication resulted in a distinct “anthropogenic assemblage” in the surface sediments. Its structure relates directly to the distance from the mouth of the Vistula River. In the surface assemblages of the Vistula Lagoon, the number of salt-tolerant diatoms increased with the salinity of the basin. Locally, a large number of pollution-resistant taxa was also observed.

Abstract

Paramecium bursaria (Ciliophora) is a cosmopolitan unicellular organism that plays a significant role in aquatic ecosystems. P. bursaria contains symbiotic algae and this association is a mutual symbiosis. The aim of the present study was to determine the activity of photosystem II (PSII) in Chlorella sp. inside P. bursaria cells. Ciliates were incubated for 7 days at different temperatures from 6 to 18°C, under the circadian cycle: 12 h light/12 h dark, at light intensity of 200 μmol m-2 s-1 and under constant darkness conditions. The control group was kept at a temperature of 18°C under constant light conditions. Changes in PSII were monitored using different fluorescence parameters. Differences in responses between endosymbiotic algae of two P. bursaria strains – Ard7 from a warm climate and KD64 from a cold climate – were determined. The highest photosynthetic activity of P. bursaria green endosymbionts was observed at a temperature of 18°C, regardless of the light conditions. Algae from warm climate were more sensitive to cold temperature stress than algae from P. bursaria collected in cold climate.

Published: June 2018

Abstract
Video recording of the manual version of the ASTM D445, Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity), effectively automated this method, resolved ergonomic concerns, reduced chemical exposure of an operator, drastically reduced probability of errors of the operator, significantly improved productivity, and simplified the analyst training process and work turnover. The accuracy of results is acceptable from the standpoint of the ASTM D445 method.
Full-Scale Load Testing of 75–90-m-Long Post-Grouted Drilled Shafts in Suzhou Stiff Clay
Authors: Lu Ye , Tan Yong , Lan Hongliang 
Published: June 2018

Abstract
This article evaluates the effects of post-grouting on axial behavior of long drilled shafts in stiff clay. Static axial compression and tension load tests were conducted on four ungrouted and six post-grouted shafts to investigate the effects of post-grouting on axial capacity and load-transfer mechanism. After post-grouting, axial capacity increased more than 100 %. Prior to failure, the relationship between the normalized axial load Q/Qmax and shaft head displacement Δ/D was nonlinear for ungrouted shafts. Compared with cases presented in the literature, much greater shaft displacements were required to mobilize shaft tip resistance and skin resistance, indicating a softer load-displacement response. The contribution of tip resistance to the overall load capacity was small for both ungrouted and post-grouted shafts because of their length. Shaft load capacity was significantly underestimated by the standard penetration test (SPT)-based method and α-method and was more reasonably estimated by the β-method. The cone penetration test (CPT) direct method yielded generally reliable predictions of skin resistance mobilized in the upper stiff clay soils; however, this method significantly underestimated skin resistance in the underlying very stiff to hard clay layers. Considering uncertainties in current design methods, results of this study suggest that field load tests are needed prior to construction to obtain site-specific design parameters.
Analysis of Multiaxial Near-Surface Residual Stress Fields by Energy- and Angle-Dispersive X-ray Diffraction: Semi- Versus Nondestructive Techniques

Published: June 2018

Abstract
Under laboratory conditions while applying angle-dispersive X-ray diffraction, the information depth in steel is usually restricted to less than 10 μm. Access to residual stresses induced by mechanical, chemical, or both types of surface treatment in deeper regions requires either the application of the layer removal method or an analysis with highly penetrating X rays and synchrotron radiation, respectively. Successive layer removal yields the actual residual stress depth profiles σij(z) up to any depth below the surface, but this is time consuming and semidestructive. High-energy X-ray diffraction performed in the energy-dispersive mode avoids these drawbacks, but it provides only the Laplace stresses, σij(τ), which have to be transformed back into the real space in order to obtain the actual stress-depth profile σij(z). Using an example of a uniaxially ground steel specimen, it is shown that the layer removal method and the energy-dispersive diffraction method for X-ray stress analysis when performed in reflection geometry yield comparable results in the case of the in-plane stress components σ11 and σ22. However, significant differences were observed concerning the out-of-plane stresses, which can be attributed to the boundary conditions that the σi3 components must satisfy at the free surface. It is demonstrated that stress redistribution at the newly generated surfaces after successive layer removal leads to an underestimation of the shear stresses σ13. The analysis of the out-of-plane normal stress component σ33 is shown to require nondestructive measurements.

Authors: Anli Selcuk , Karimian-Tabrizi Afsaneh , Moritz Anton , Monsefi Nadejda 
Published: June 2018

Background: The lower patency rate of vein grafts (VG) in comparison to arterial grafts may be related to vein valves, which favor turbulences and thrombosis that lead to graft failure. The aim of this study was to determine the outcome of patients with valvulotomized VG after coronary artery bypass grafting (CABG) procedure. Methods: From 2007 to 2014, 233 patients with a mean age of 67 ± 9 years had CABG or combined CABG and valve procedures. Valvulotomized saphenous VG and arterial grafts were used. Clinical follow-up and outcome were evaluated after 6.3 ± 2 years. The graft patency was rated with multislice computed tomography in 57 patients and coronary angiography in 29 patients 3.1 ± 2 years postoperatively.Results: Overall, 168 patients had segregated CABG surgery, and 65 patients received additional procedures, with mean 2.7 ± 1 arterial and 1.5 ± 0.7 venous anastomoses. The 30-day-mortality in isolated CABG patients was 2%. Survival at five years was 80%. Major adverse cardiac and cerebrovascular events (MACCE) free rate at five years was 80%. At the last follow up (mean 6.3 years), 94% of the patients were in Canadian Cardiovascular Society (CCS) class 0. The quote of patent valvulotomized VG was 96.1% compared to a patency rate of 96.7% for the arterial grafts in the subgroup undergoing angiography or computed tomography of the heart. Conclusion: Our data demonstrate good mid-term results of graft patency, and comparable clinical results in patients undergoing CABG with valvulotomized VG. A longer follow-up period and a higher number of bypass graft imaging examinations are necessary to affirm our results.

Published: June 2018

ackground: Repeated thoracic aorta repair is increasingly common. With the increase in hybrid procedures, determination of the best treatment strategy requires evaluation of the clinical outcomes of classic open surgery. Methods: We retrospectively reviewed 119 patients (84 men and 35 women, aged 51.0 ± 16.7 years) with a history of open repair involving the thoracic aorta above the diaphragm. The patients underwent an average of 1.3 ± 0.8 surgeries (range: 1-8) on the thoracic aorta before the final operation. Clinical outcomes were evaluated on the basis of the need for emergency surgery, indications for surgery, pathologic causes, and other operative variables.Results: Hospital mortality was 6.7% (n = 8). Postoperative bleeding occurred in 16% (n = 19). On multivariable analysis, emergency surgery (odds ratio [OR], 19.005; P = .003; 95% confidence interval [CI], 2.710-133.305) and cardiopulmonary bypass (CPB) time (OR, 1.562 per 30 minutes; P = .007; 95% CI, 1.126-2.165) were predictors of hospital death. Emergency surgery (OR, 4.105; P = .029; 95% CI, 1.157-14.567) and CPB time (OR, 1.189 per 30 minutes; P = .035; 95% CI, 1.012-1.396) were also associated with postoperative bleeding, in addition to surgery for an infectious cause (OR, 10.824; P = .010; 95% CI, 1.755-66.770). Estimated survival at 1, 5, and 7 years was 86.6%, 80.5%, and 78.2%, respectively. Conclusion: Despite the variety of preoperative conditions and operations performed, repeated open surgery for thoracic aorta repair can be performed with acceptable early and late outcomes.
Dis/Orientation: Rhythmic Bodies and Corporeal Orature in The Fits
Authors: Benthaus Elena 
Published: June 2018

In Anna Rose Holmer’s 2015 film The Fits, 11-year old protagonist Toni is depicted as moving between the steady rhythms of the local boys’ boxing club and the highly syncopated, vertiginous, call-and-response rhythms of the local girls’ drill dance team, all of which culminates into a polyrhythmic, contagious, and seemingly uncontrollable, uncontainable, and indescribable form of fitful corporeal fainting spell. Since the film does not overly depend on dialogue, the film’s affective-ness relies on the protagonists’ expressive and active corporeality, as that which moves in between different spaces and rhythms. Often described as a coming-of-age story, in this article, I will be looking at The Fits as a dance film in order to examine the film through its beats and rhythms by drawing specifically on Thomas DeFrantz’ concept of corporeal orature, Julian Henriques’ notion of affective vibration, Imani Perry’s notion of the cypher, and Brenda Dixon Gottschild’s concept of polycentrism/polyrhythmicality. In relation to this I propose that spectators are drawn into this movie by a constant negotiation of movement as that which sits at the border of consciousness, giving access to a spectatorial experience, in which the moving, rhythmic bodies-on-screen serve simultaneously as points of orientation and disorientation.

Published: June 2018

Purpose of the study:World over, transportation infrastructure projects face delays in commissioning and India is no exception. This study is carried out with an objective to specifically identify the critical delay factors in the commissioning of metro rail projects in India.
Methodology: A questionnaire survey was conducted to identify the major causes of delay from the opinion of clients, contractors and consultants. Calculation of Relative Importance Index (RII) for the shortlisted factors yielded the ranking. The ranking by various categories of respondents was analysed using Spearman’s rank coefficient.
Main Findings:The study concluded in identification of 10 most critical delay-factors from a list of 49 shortlisted factors spread across 7 categories. The identified factors included: (1) Delay in land acquisition and site handover to contractor, (2) Shifting of utilities and contingency works, (3) Scope change, (4)Delay in payments, (5) Effects of unforeseen subsurface and changing ground condition, (6) Shortage of construction materials in the market, (7) Delays in design approvals and decision making, (8) Shortage of labour, (9) Lack of data collection and survey before design, and (10) Delay in obtaining permits from local body.
Implications: Project management interventions based on the identified critical factors of delay can improve the delivery of upcoming metro rail projects in terms of schedule compliance.
Applications of this study:The Application of suitable course correction measures targeting the critical factors can result in mitigation of delays.
Novelty/Originality of this study:The study is one of its kind attempt to investigate all the commissioned metro rail projects in India for analyzing delays in the Indian urban rail sector.
Avaliação dos instrumentos de medida de afeto e bem-estar no trabalho publicados em periódicos de Psicologia e Administração de 1996 a 2015
Authors: Resende Sonia , Neiva Elaine Rabelo 
Published: June 2018

Este artigo analisa as produções científicas publicadas nas revistas e periódicos das áreas de Psicologia e de Administração, entre 1996 e 2015, que propuseram a criação e/ou validação de instrumentos de medida utilizando análise inferencial, em temas ligados a afetos e bem-estar no trabalho, verificando escalas desenvolvidas no Brasil neste período, seus constructos e fatores, classificando-as de acordo com o escopo (novo instrumento, adaptação/versão brasileira de instrumento estrangeiro, validação fatorial com outras amostras/ ocupações) e com o foco (indivíduo ou contexto de trabalho). Utilizando-se base de dados em Excel com 860 artigos de Comportamento Organizacional, foram triados 26 artigos atendendo os critérios de terem medidas inferenciais nos subtemas Afeto e Bem-Estar no Trabalho. Os resultados demonstram que mais de um terço das escalas de medida quantitativa avaliadas correspondem aos temas de Bem-estar (19%) e de Satisfação no Trabalho (15%), que 42% dos artigos eram tradução/ adaptação de escalas estrangeiras, e 35% de criação e validação fatorial de escalas nacionais, e que 70% das medidas voltam-se para avaliação de características individuais, tornando então o trabalhador como variável de ajuste organizacional. Considera-se que o direcionamento para replicações de medidas criadas ou já adaptadas ao Brasil, possibilitando novas evidências de validação fatorial, bem como sua efetiva publicação em periódicos da área de Psicologia e Administração, ampliaria a generalização dos resultados e o fortalecimento dos constructos teóricos desenvolvidos para os fenômenos organizacionais, para melhor divulgação e aplicação no contexto laboral.
