Suffering and sovereignty
Authors: Fordahl Clayton
Published: June 2018

This article investigates the recent martyrdom of the French Catholic priest Jacques Hamel in order to assess the possibilities of sacrificial commemoration in a world that is increasingly globalized, increasingly secularized, and also increasingly subject to the capricious violence of religiously-infused terrorism. I argue that under contemporary conditions it has become increasingly difficult to articulate a meaningful form of sacrifice that exists beyond the logic of sovereignty. However, I conclude by identifying rare and fleeting instances of martyrdom which seem to promise the return to the concept’s counter-sovereign heritage.
The mad animal
Authors: Ross Lachlan
Published: June 2018

The following article defines Castoriadis’ concepts of the radical imagination and the social imaginary as a platform for a discussion of some motifs important to Castoriadis: the nature of human subjectivity, the nature of ‘reality’, the role and scope of the human imagination, the importance of freedom, the question of whether or not we are free (i.e. how sick/diminished/vulnerable is the second epoch of autonomy that broke open in/as modernity), and the roles of science, politics and philosophy in human social life. The central work on the radical imagination and the social imaginary is of course more than an arbitrary jumping-off point: this paper argues that understanding these concepts is vital if one is to understand the core elements of Castoriadis’ writings and his broader emancipatory project.
You Can Observe a Lot by Watching: Hughlings Jackson’s Underappreciated and Prescient Ideas about Brain Control of Movement
Authors: Berkowitz Ari
Published: June 2018

John Hughlings Jackson, the 19th-century British neurologist, first described what are today called Jacksonian seizures. He is generally associated with somatotopy, the idea that neighboring brain regions control neighboring body parts, as later represented pictorially in Wilder Penfield’s “homunculus,” or little man in the brain. Jackson’s own views, however, were quite different, though this is seldom appreciated. In an 1870 article, Jackson advanced the hypotheses that each region of the cerebrum controls movements of multiple body parts, but to different degrees, and that the “march” of movements that typically occurs during Jacksonian seizures is caused by the downstream connections of the overactive neurons at the seizure focus, rather than a somatotopic organization of the cerebrum. Jackson’s hypotheses, which were based almost entirely on his careful observations of movements during seizures, are well within the range of current hypotheses about how the frontal lobe is organized to control movements and thus deserve renewed attention.
A Scoping Review of the Literature on Public Solicitations for Living Organ and Hematopoietic Stem Cell Donations
Authors: Shanker Ruby Rajendra , Anthony Samantha J. , Wright Linda
Published: June 2018

Introduction:

Evolving methods of communication have increased public appeals for living organ and hematopoietic stem cell donations from strangers, giving public solicitations more visibility. Within the academic literature, perspectives have been divisive, reflecting ethical justifications for and against appeals for living unrelated donors. Transplant programs and clinicians face a variety of ethical dilemmas when patients and their solicited donors present to the hospital.

Objective:

A scoping review methodology was designed to (1) explore the academic literature and (2) summarize and disseminate key research findings.

Methods:

We used the Arksey & O’Malley framework for conducting and reporting scoping reviews and to review the prominent ethical arguments, counterarguments, and policy implications in the literature. From 4616 articles identified through MEDLINE, EMBASE, PsycInfo, and CINAHL, we screened titles and abstracts to assess eligibility for full-text review.

Results:

We retrieved 280 full texts, extracted data from 61, and coded and analyzed 41 papers. Of these, 36 were from or based in the US context. Two articles originated from Canada. Three articles addressed public solicitations of hematopoietic stem cell donation. We mapped themes under 3 major headings related to public solicitations of living unrelated donors for organs and hematopoietic stem cells: (1) interpretations and modes, (2) ethical arguments for and against, and (3) policy implications and suggestions to address challenges for clinical practice.

Discussion:

The academic literature contains divisive perspectives of public solicitations for organ and hematopoietic stem cell donation, each of which deserves further reflection for implications for policy and practice.
Transformational school leadership as a key factor for teachers’ job attitudes during their first year in the profession
Authors: Thomas Laura , Tuytens Melissa , Devos Geert , Kelchtermans Geert , Vanderlinde Ruben
Published: June 2018

Teacher attrition is a global concern that is particularly prevalent among beginning teachers. Teachers’ intrinsic motivation to teach, affective organisational commitment and job satisfaction are considered job attitudes that stop them from dropping out of the profession. This study explores the interplay between factors at the school level (i.e. transformational leadership of the principal, professional collegial support) and the teacher level (i.e. self-efficacy) influencing these job attitudes. A sample of 292 first-year primary-school teachers participated. The results of the path analysis demonstrated that transformational leadership of the principal is directly related to teachers’ job attitudes in a positive way. Moreover, transformational leadership of the principal is also indirectly related to these attitudes, via both professional collegial support and teachers’ self-efficacy. Implications for the supportive role of the principal in the teachers’ first year in the profession are discussed.
Democracy and education: ‘In spite of it all’
Authors: Clarke Matthew
Published: June 2018

This article draws on psychoanalytic theory to reconsider democracy, education and their relationship. The author argues for the pervasive presence of fantasmatic thinking in relation to both democracy and education in much media and policy discussion, which fuels our subjection to ideology through cruelly optimistic promises about the future benefits which will accrue from current sacrifice – promises which are exposed as false by persistent and growing economic inequality and the substantial failure to fulfil its inflated promises that is endemic to modern education. By contrast, the article argues for a politics grounded in an acceptance of constitutive lacking status as desiring subjects, which recognises and embraces the enjoyment that comes from loss, thereby freeing us from the spell of compulsive repetition reflected in our fixation on fantasmatic programmes of redemption in both politics and education. This might open possibilities for realising, albeit indirectly and obliquely, the goals which continually escape our more overt attempts to grasp them. The author’s overall argument is that the flaws and illusions characterising our experiences of democracy and education are not reasons to abandon them, but instead suggest a need to rework our relationship to them in less fantasmatic ways, ‘in spite of it all’.
Gist Perception of Image Composition in Abstract Artworks
Authors: Schwabe Kana , Menzel Claudia , Mullin Caitlin , Wagemans Johan , Redies Christoph
Published: June 2018

Most recent studies in experimental aesthetics have focused on the cognitive processing of visual artworks. In contrast, the perception of formal compositional features of artworks has been studied less extensively. Here, we investigated whether fast and automatic processing of artistic image composition can lead to a stable and consistent aesthetic evaluation when cognitive processing is minimized or absent. To this aim, we compared aesthetic ratings on abstract artworks and their shuffled counterparts in a gist experiment. Results show that exposure times as short as 50 ms suffice for the participants to reach a stable and consistent rating on how ordered and harmonious the abstract stimuli were. Moreover, the rating scores for the 50 ms exposure time exhibited similar dependencies on image type and self-similarity and a similar pattern of correlations between different rating terms, as the rating scores for the long exposure time (3,000 ms). Ratings were less consistent for the term interesting and inconsistent for the term pleasing. Our results are compatible with a model of aesthetic experience, in which the early perceptual processing of the formal aspects of visual artworks can lead to a consistent aesthetic judgment, even if there is no cognitive contribution to this judgment.
Cross-sectional correlates of myeloperoxidase and alpha-1-acid glycoprotein with adiposity, atherogenic and hematological indices in metabolic syndrome patients with or without diabetes
Authors: Alquoqa Reem Sami , Kasabri Violet , Naffa Randa , Akour Amal , Bustanji Yasser
Published: June 2018

Background:

Type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) are associated with obesity, which triggers the release of inflammatory substances. Myeloperoxidase (MPO), a peroxidase enzyme, and alpha-1-acid glycoprotein (AGP), an acute-phase protein, are known to be released in patients with inflammatory conditions and cardiovascular disease (CVD).

Methods:

In this study, we investigated the correlation between MPO and AGP levels in pre/diabetic and MetS patients by conducting a cross-sectional study at The University of Jordan Hospital (UoJH) at the diabetes and endocrinology outpatient clinics. A total of 237 patients were recruited and assessed for eligibility. Of these, 149 patients were excluded, and 88 patients were assigned as: 29 patients in a healthy lean normoglycemic control group; 29 patients in a nondiabetic MetS group; and 30 patients in a prediabetic/newly diagnosed T2DM MetS group.

Results:

MPO levels were only significantly higher in the nondiabetic MetS group compared with the control group ( p = 0.026). AGP levels were significantly higher in both nondiabetic MetS and MetS-prediabetic/T2DM groups versus control ( p = 0.007 and p = 0.015, respectively). Both biomarkers lacked inter-MetS-group discrepancy.

Conclusions:

Our results demonstrate an association between MPO and AGP with obesity and hyperglycemia, alongside their correlation with several adiposity, hematology and atherogenicity indices. Our findings reinforce the use of MPO and AGP as potentially putative and surrogate predictive/prognostic tools for MetS and its related disorders.
Impact of donor chest radiography on clinical outcome after lung transplantation
Authors: Bozovic Gracijela , Adlercreutz Catharina , Björkman-Burtscher Isabella M , Reinstrup Peter , Ingemansson Richard , Skansebo Elin , Geijer Mats
Published: June 2018

Background

Organ donation guidelines recommend a “clear” conventional bedside chest radiograph before lung transplantation despite only moderate accuracy for cardiopulmonary abnormalities.

Purpose

To evaluate the influence of donor image interpretation on lung transplantation outcome in recipients by following early and late complications, one-year survival, and to correlate imaging findings and blood gas analysis with lung transplantation outcome in recipients.

Material and Methods

In 35 lung donors from a single institution clinical reports and study reviews of imaging findings of the mandatory bedside chest radiographs and blood gas analyses were compared with clinical outcome in 38 recipients. Hospitalization time, peri- and postoperative complications, early complications (primary graft dysfunction, infection), 30-day and one-year survival, and forced expiratory volume in 1 s percentage of predicted normal value (FEV1%) at one-year follow-up were analyzed.

Results

Findings in clinical reports and study reviews differed substantially, e.g. regarding reported decompensation, edema, infection, and atelectasis. No correlation was shown between imaging findings in clinical report or study review and blood gas analyses in the lung donors compared to postoperative outcome in recipients.

Conclusion

The interpretation of the mandatory chest radiograph in its present form does not influence one-year outcome in lung transplantation. Larger imaging studies or a change in clinical routine including computed tomography may provide evidence for future guidelines.

Authors: Cheung Zoe B. , Vig Khushdeep S. , White Samuel J. W. , Lima Mauricio C. , Hussain Awais K. , Phan Kevin , Kim Jun S. , Caridi John M. , Cho Samuel K.
Published: June 2018

Study Design:

Retrospective cohort study.

Objectives:

To determine the effect of obesity (body mass index >30 kg/m2) on perioperative morbidity and mortality after surgical decompression of spinal metastases.

Methods:

The American College of Surgeons National Surgical Quality Improvement Program database is a large multicenter clinical registry that collects preoperative risk factors, intraoperative variables, and 30-day postoperative morbidity and mortality outcomes from hospitals nationwide. Current Procedural Terminology codes were used to query the database for adults who underwent decompression with laminectomy for treatment of metastatic spinal lesions between 2010 and 2014. Patients were separated into 2 cohorts based on the presence of absence of obesity. Univariate analysis and multivariate logistic regression analysis were used to analyze the effect of obesity on perioperative morbidity and mortality.

Results:

There was a significantly higher rate of venous thromboembolism (VTE; obese 6.6% vs nonobese 4.2%; P = .01) and pulmonary complications (obese 2.6% vs nonobese 2.2%; P = .046) in the obese group compared with the nonobese group. The nonobese group had prolonged hospitalization (obese 62.0% vs nonobese 69.0%; P = .001) and a higher incidence of blood transfusions (obese 26.8% vs nonobese 34.2%; P < .001). On multivariate analysis, obesity was found to be an independent risk factor for VTE (odds ratio = 1.75, confidence interval = 1.17-2.63, P = .007).

Conclusions:

Obese patients were predisposed to an elevated risk of VTE following laminectomy for spinal metastases. Early postoperative mobilization and a low threshold to evaluate for perioperative VTE are important in these patients in order to appropriately diagnose and treat these complications and minimize morbidity.
MicroRNA-644a promotes apoptosis of hepatocellular carcinoma cells by downregulating the expression of heat shock factor 1

Published: June 2018

In this study, we investigated the role of microRNA-644a (miR-644a) in the growth and survival of hepatocellular carcinoma (HCC) cells. MiR-644a levels were lower in HCC tissues than in adjacent peri-cancerous tissues (n = 135). MiR-644a expression was inversely correlated with heat shock factor 1 (HSF1) expression, tumour diameter and TNM stage. Moreover, HepG2 and SMMC-7721 cell lines showed lower miR-644a expression than normal L-O2 hepatocytes. MiR-644a overexpression in HepG2 and SMMC-7721 cells increased apoptosis by downregulating HSF1. Dual luciferase reporter assays confirmed the presence of a miR-644a binding site in the 3’-untranslated region (3’-UTR) of HSF1. Xenograft tumours derived from SMMC-7721 cells transfected with a miR-664a mimic showed less growth than tumours derived from untransfected controls. Protein chip analysis revealed that miR-644a-overexpressing SMMC-7721 and HepG2 cells strongly expressed pro-apoptotic BH3-only proteins, such as BID, BAD, BIM, SMAC, Apaf-1 and cleaved caspases-3 and -9. These findings suggest miR-644a promotes apoptosis in HCC cells by inhibiting HSF1.
Sociology of the professions: what it means for podiatry
Authors: King Olivia , Borthwick Alan , Nancarrow Susan , Grace Sandra
Published: June 2018

Background

The health professions have progressed and evolved considerably over the last few decades in response to demographic, technological, societal and political changes. They continue to do so as the volume and complexity of population health needs steadily increase. Role boundary expansion is among the key changes to the health professions, including podiatry to meet demand. Nonetheless podiatry's role boundary expansion has not been achieved swiftly or without resistance from neighbouring and dominant professions. This paper seeks to explain the nature of this resistance with respect to the sociology of the professions literature and to shed light on some of the factors and processes at play when role boundary changes arise in health care.

Discussion

Six of the most contemporaneously relevant sociology of the professions theories are summarised:Taxonomic, Marxian, Bourdieusian, Foucauldian, Boundary Work and Neo‐Weberianparadigms.

Conclusion

This review highlights that some paradigms are more relevant than others in the current socio‐political landscape. It also illustrates that there is a common theme underlying each approach to defining the professions and their boundaries: competition. This may help health professionals, including podiatrists, to understand and manage the challenges and resistance experienced when professions attempt to expand role boundaries to meet increasing and changing population health needs.
Numerical shape-from-shading revisited
Authors: Santo Hiroaki , Samejima Masaki , Matsushita Yasuyuki
Published: June 2018

This paper revisits the numerical shape-from-shading method proposed in early 1980s. The original problem is non-convex due to the unit norm constraint for surface normal, and the existing approaches including the original Ikeuchi and Horn’s work uses approximate solution strategies for the original problem. This paper instead studies relaxation strategies for the original non-convex constraint and describes corresponding solution techniques that are built upon advanced convex optimization. We analyze the effect of the relaxations in terms of resulting accuracy and computational complexity.

Published: June 2018

Purpose

Initiatives such as The Cancer Genome Atlas and International Cancer Genome Consortium have generated high-quality, multiplatform molecular data from thousands of frozen tumor samples. Although these initiatives have provided invaluable insight into cancer biology, a tremendous potential resource remains largely untapped in formalin-fixed, paraffin-embedded (FFPE) samples that are more readily available but which can present technical challenges because of crosslinking of fragile molecules such as RNA.

Materials and Methods

We extracted RNA from FFPE primary melanomas and assessed two gene expression platforms—genome-wide RNA sequencing and targeted NanoString—for their ability to generate coherent biologic signals. To do so, we generated an improved approach to quantifying gene expression pathways. We refined pathway scores through correlation-guided gene subsetting. We also make comparisons to The Cancer Genome Atlas and other publicly available melanoma datasets.

Results

The comparison of the gene expression patterns to each other, to established biologic modules, and to clinical and immunohistochemical data confirmed the fidelity of biologic signals from both platforms using FFPE samples to known biology. Moreover, correlations with patient outcome data were consistent with previous frozen-tissue–based studies.

Conclusion

FFPE samples from previously difficult-to-access cancer types, such as small primary melanomas, represent a valuable and previously unexploited source of analyte for RNA sequencing and NanoString platforms. This work provides an important step toward the use of such platforms to unlock novel molecular underpinnings and inform future biologically driven clinical decisions.

Published: June 2018

Software Containers are changing the way scientists and researchers develop, deploy and exchange scientific software. They allow labs of all sizes to easily install bioinformatics software, maintain multiple versions of the same software and combine tools into powerful analysis pipelines. However, containers and software packages should be produced under certain rules and standards in order to be reusable, compatible and easy to integrate into pipelines and analysis workflows. Here, we presented a set of recommendations developed by the BioContainers Community to produce standardized bioinformatics packages and containers. These recommendations provide practical guidelines to make bioinformatics software more discoverable, reusable and transparent.  They are aimed to guide developers, organisations, journals and funders to increase the quality and sustainability of research software.

Published: June 2018

BACKGROUND

Measurement standardization of the catalytic concentration of α-amylase in serum is based on 3 pillars: the primary reference measurement procedure (PRMP), reference laboratories, and suitable certified reference materials (CRMs). Commutability is a prerequisite when using a CRM for calibration and trueness control of routine methods or for value transfer from the PRMP to end-user calibrators of routine methods through a calibration hierarchy.

METHODS

We performed a commutability study with 30 serum pools and 5 candidate reference materials (RMs) for pancreatic α-amylase using an automated version of the PRMP and 5 different routine methods. Four candidate RMs had an artificial matrix, each with a different composition, and 1 candidate RM was based on human serum. Data were analyzed according to a linear regression analysis with prediction interval as described in the Clinical and Laboratory Standards Institute guideline EP30-A and a difference in bias analysis as described in the recommendations of the IFCC Working Group on Commutability.

RESULTS

The commutability profile of the 4 candidate RMs with an artificial matrix was variable. Only 1 candidate RM, with human serum albumin in the matrix, showed a good profile like that of the candidate RM based on serum. The comparison of both commutability assessment approaches indicated some differences because of inconclusive results for the difference in bias approach, suggesting a large uncertainty on the commutability assessment.

CONCLUSIONS

A CRM for pancreatic amylase in an artificial matrix can be commutable for routine methods using the same substrate as the PRMP, but the matrix composition is crucial.

The poet as screenwriter: Landscape and protagonism in Papu Curotto’s Esteros
Authors: Bollig Ben
Published: June 2018

Gerardo ‘Papu’ Curotto’s debut feature Esteros (Estuaries, Argentina, 2016) tells a story of young love and second chances in Argentina’s northern Corrientes province. With its lush settings, endearing performances and positive denouement, it echoes recent LGBTQ+-themed Argentine successes on the international festival circuit. But Esteros can also be viewed from another angle, that of adaptation studies. A focus on the screenwriter Andi Nachon’s contribution reveals the subtle politics of a film that touches on land ownership, farming methods and environmentalism. By highlighting the screenwriter’s role, alongside that of the director, a number of apparently otiose leitmotifs and passing comments come to make sense as part of a broader comment on environmental politics in Argentina. Thus a study of Esteros that assesses the links between the film and Nachon’s poetry opens up the movie as a work of political critique and enriches our understanding of the screenwriter’s role in adaptations.

Published: June 2018

The aim of the present study is to examine the impact of instruction with visualization of identities in form in mathematics on students’ achievement and opinions. The study employs an explanatory design, a mixed method, through which qualitative and quantitative data were collected and analysed. Quantitative data in the study were obtained using the Identities and Binomial Exponential Achievement Test to determine the effect of visualization-assisted instruction on students’ academic achievement. Qualitative data, regarding the student views on the subject, were collected through a structured interview form. Participants of the study, 53 students, were selected by appropriate sampling method among the first-year univeristy students. The t-test and one-way covariance analysis were used to analyse the quantitative data and the content analysis method was used for the qualitative data. The results obtained from quantitative data indicated that instruction of algebraic expressions through mathematical visualization increased student achievement in comparison to traditional instruction. On the other hand, the qualitative data indicated that visualization facilitated a positive development in instruction of algebraic expressions, rendered the teaching process to be more interesting and enjoyable and led the students to acquire conceptual learning skills instead of memorizing.

Mass propagation of tissue culture produced seaweed seedling was conducted in the pond. The present study aims to evaluate the growth of tissue culture produced seaweed seedling of Gracilaria verrucosa, its agar yield and related water quality variables during propagation in pond. The seedling propagation was conducted in pond using long line method for 9 cycles (30 days per cycle). The daily growth rate was calculated by weighing 30% of the total amount of seaweed at ropes line every 15 days. Agar yield was analyzed every 30 days in hot water extraction method. Water quality monitoring was conducted every 15 days. The data of daily growth rate and agar yield were analyzed descriptively. A simple linear regression analysis was conducted in order to analyze the relationship between growth and agar yield as well relationship between water quality variables, growth and agar yield. The result showed that the average daily growth rate of nine cycles was 3.38±1.49%. The highest agar yield was yielded from cycle II (27.84±1.60%) and the lowest was in cycle I (10.30%±2.15). There is no relationship between daily growth rate and agar yield (R2=0.055). Daily growth rate was mostly influenced by phosphate (P<0.05), nitrate (P<0.05), salinity (P<0.05) and light penetration (P<0.05). Meanwhile, agar yield was mostly influenced by temperature (P<0.05) and light penetration (P<0.05).

Published: June 2018

The holothuroid spawning can be succesful depend on varoius factors such as salinity, temperature, primary productivity and other physiological adaptation toward environment influences. The salinity fluctuation is one of the environment factors, which influence and can cause various osmotic pressure of coelomic fluid of Holothoroid and also gonad maturity stage. Holothuroid (sea cucumber), Paracaudina australis, is overexploited in Kenjeran waters, Surabaya, East Java. The study was aimed to reveal relationship between gonad maturity stage and level of osmotic work of sea cucumber P. australis. Fifty samples of P. australis were collected monthly.  Coelomic fluid samples of approximately 200–1000 µl were obtained from all samples using disposable insulin syringes. There were 37 holothuroids classified in the late maturity (stage 5), 74 holothuroid in the earlier maturity stage (stage 1). Gonad maturity stage 5 (late maturity) could be reached on December 2016. Contrasly, the gonad maturity stage 1 (earlier maturity) was found on August 2016. The analysis  of coelomic fluid showed that the average value of level of osmotic work  ranged 70  to 91 mOsm/L H2O in the earlier gonad maturity stage. Contrasly, in the late maturity, the average value of level of osmotic work ranged 118 to 156 mOsm/L H2O. There is relationship between gonad maturation stage and level of osmotic work. From stage of gonad maturity 1 to 5, there were upward trend level of osmotic work in coelomic fluid of P. australis. Keywords: gonad maturity, osmotic, Paracaudina australis
Polska i niemiecka historia sztuki w polemicznym dyskursie - sympozjum w Rogalinie w roku 1973.
Authors: Labuda Adam
Published: June 2018

Polish and German Art History in a Polemic. The Rogalin Symposium of 1973 Summary The paper recapitulates a discussion over the book, Das Kunstwerk zwischen Wissenschaft und Weltanschauung, ed. Martin Warnke, Köln 1970, which was an aftermath of a pungent statement made by critical German art historians at the Congress of German Art Historians held in Köln in 1970. The main idea of the book was showing the “work of art as an object of ideological interests, a victim of ideological interventions” (Warnke) – in this case, those of a nationalist, Nazi, and fascist origin. A critical impulse triggered by the congress and the book was the main reason for organizing a symposium in Rogalin in 1973, during which art historians from Poznań delivered papers-comments on four articles included in the German publication. Taking into consideration the key message of the book, in the first place they focused on the methodological and theoretical assumptions adopted by German scholars. Stressing the discrepancy between the goals and assumptions of the German publication and its Polish reception, the author treats the papers delivered in Rogalin as evidence of a methodological shift in Polish art history of the early 1970s. His main observations are the following: the end of the dominant approach focusing on the artwork itself; a shift toward approaching it in terms of the communicative triad “sender-work-recipient”; acknowledging the inevitable involvement of the art historian (scholar-recipient) in that historically determined framework. It is notable that the Polish scholars virtually ignored the ideological and critical approach to the evolution of art history that was developed in the German book. Moreover, the paper presents the historical background of both the Köln conference and its proceedings as well as the specific determinants of art history in the communist Poland, particularly as regards its contacts with the two German states.
Whence subject-verb agreement? Investigating the role of topicality, accessibility, and frequency in Vera’a texts
Authors: Schnell Stefan
Published: June 2018

While the grammaticalization of subject agreement appears to be a diachronic near-universal, there has been little agreement on usage-based motivations for this crosslinguistic tendency. Three usage-based approaches – Givón’s NP detachment under topicalization, Ariel’s accessibility theory, and a set of accounts in terms of frequency-driven morphologization – are examined here in the light of corpus data from the Oceanic language Vera’a. The high frequency of overt pronouns in 1st and 2nd person subjects, as well as formal reduction in some 1st-person pronouns, observed in the corpus seem suggestive of grammaticalization of subject agreement in speech-act participants (SAPs). Yet, the remaining variation between pronominal and zero forms and the distribution of reduced forms do not appear to reflect functional factors in the way of topicalization or accessibility. Overall, frequency-driven accounts appear to fare better in explaining the Vera’a facts, in particular the distribution of 1st person zero subjects and the formal reduction of 1st person subject pronouns. The overall high levels of subject pronouns, however, are not fully accounted for by any of the three approaches; I suggest that, in addition to genre effects, the deictic and shifting nature of reference to speech-act participants may be a relevant factor.
Gender agreement is different
Authors: Forker Diana
Published: June 2018

Person and gender are typical agreement features within the clause, and crosslinguistically they are frequently part of one and the same agreement system and even expressed through the same morphological exponents. Some theories even go so far as to claim that person and gender agreement on different targets, e.g., verbs and adjectives, are instances of one and the same agreement phenomenon.

This paper discusses gender and person agreement in the Nakh-Daghestanian language Lak. It shows that the two agreement systems are formally and functionally completely separated from each other. Corpus data from Lak does not prove that gender agreement in this language is used to establish reference. Therefore it should rather be treated as concord, that is, similar to modifier agreement within the noun phrase.
The influence of bar width on bar forces and fibre shortening in low consistency pulp refining
Authors: Kerekes Richard , Meltzer Frank
Published: June 2018

This paper describes forces in pulp refiners and their influence on fibre shortening. We show that force per bar length obtained by a simple calculation from the Specific Edge Load (SEL) is a useful parameter to describe threshold force levels below which levels of fibre cutting can be avoided. Our analysis is supported by data from studies on four refiners and in one case by direct measurement of force in an operating refiner. In particular, we show that small bar widths lead to large forces and consequently thatSELmust be adjusted to lower levels to avoid fibre cutting. We also speculate on the lower limits of bar width.

Innerhalb des vom schweizerischen Nationalen Forschungsprogramms 74 „Gesundheitsversorgung“ geförderten Projekts „Die spirituelle Dimension in der Schmerzbehandlung“ wurden 37 narrative Interviews von chronischen Schmerzpatientinnen und -patienten aus dem deutschen Projekt „krankheitserfahrungen.de“ untersucht. Im Rahmen einer Sekundäranalyse wurden diese inhaltsanalytisch und sprachlich feinanalytisch im Hinblick auf spirituelle Bezüge analysiert. Aus den vollständig transkribierten Interviews ergaben sich 21 Passagen aus 14 Interviews, in denen Schmerzpatientinnen und -patienten über spirituelle Aspekte sprachen. Drei Erzählkategorien wurden herausgearbeitet: (1) die Aushandlung, ob und wie über Spiritualität gesprochen wird, (2) Spiritualität als Ressource und (3) Schmerz als Herausforderung für die Spiritualität. Die Frage nach der Aushandlung spiegelt die Schwierigkeit der Patientinnen und Patienten wider, in klinisch-therapeutischen Kontexten spirituelle Aspekte zu thematisieren. Die Ergebnisse der Analyse weisen auf die Herausforderung hin, Patientinnen und Patienten im klinischen Setting auf ihre spirituellen Ressourcen und Bedürfnisse anzusprechen.
The Floquet Theory of the Two-Level System Revisited
Authors: Schmidt Heinz-Jürgen
Published: June 2018

In this article, we reconsider the periodically driven two-level system especially the Rabi problem with linear polarisation. The Floquet theory of this problem can be reduced to its classical limit, i.e. to the investigation of periodic solutions of the classical Hamiltonian equations of motion in the Bloch sphere. The quasienergy is essentially the action integral over one period and the resonance condition due to Shirley is shown to be equivalent to the vanishing of the time average of a certain component of the classical solution. This geometrical approach is applied to obtain analytical approximations to physical quantities of the Rabi problem with linear polarisation as well as asymptotic formulas for various limit cases.

1 Relaxation Data

Published: June 2018

We employed FT-IR and NMR experiments to investigate the influence of a cell-mimicking crowding environment on the structure and dynamics of an elastin-like peptide (ELP) with the sequence GVG(VPGVG)3, which – due to a high number of hydrophobic amino acid side chains – exhibits an inverse temperature transition (ITT). As simplified crowding agent, we used 30 wt% Ficoll. The FT-IR data revealed the well-known broad ITT above ~25°C, as observed by the decrease of the relative population of random coil structures and the concomitant increase of type II β-turns. Interestingly, the addition of Ficoll leads to a destabilizing effect of type II β-turn structures. This is in contrast to the expected excluded-volume effect of the macromolecular crowder, but can be explained by weak interactions of the peptide with the polysaccharide chains of the crowding agent. Further, the crowding agent leads to the onset of a reversal of the folding transition at high temperatures. The full assignment of the ELP allowed for a residue-specific investigation of the dynamic behavior of ELP by NMR. Due to a strong change of microscopic viscosity between native/buffered conditions and crowded conditions, relaxation data remain inconclusive with respect to the observation of an ITT. Hence, no quantitative details in terms of internal conformational changes can be obtained. However, temperature dependent differences in the 13C relaxation behavior between core and terminal parts of the peptide indicate temperature induced changes in the internal dynamics with generally higher internal mobility at chain ends: This is in full agreement with FT-IR data. In harmony with the FT-IR analysis, macromolecular crowding does not lead to significant changes in the relaxation behavior.

Negra, Y, Chaabene, H, Fernandez-Fernandez, J, Sammoud, S, Bouguezzi, R, Prieske, O, and Granacher, U. Short-term plyometric jump training improves repeated-sprint ability in prepuberal male soccer players. J Strength Cond Res 34(11): 3241–3249, 2020—This study examined the effects of a short-term (i.e., 8 weeks) combined horizontal and vertical plyometric jump training (PJT) program in combination with regular soccer-specific training as compared with soccer-specific training only on jump and change of direction (CoD) performances, speed, and repeated-sprint ability (RSA) in prepuberal male soccer players. Twenty-four players were recruited and randomly assigned to either a PJT group (PJTG; n = 13; 12.7 ± 0.2 years) or an active control group (CONG; n = 11; 12.7 ± 0.2 years). The outcome measures included tests for the assessment of jump performance (drop jump from 20- to 40-cm height [DJ20 and DJ40] and 3-hop test [THT]), speed (20-m sprint), CoD (T-test), and RSA (20-m repeated shuttle sprint). Data were analyzed using magnitude-based inferences. Within-group analyses revealed large performance improvements in the T-test (d = −1.2), DJ20 (d = 3.7), DJ40 (d = 3.6), THT (d = 0.6), and the RSAtotal (d = −1.6) in the PJTG. Between-group analyses showed greater performance improvements in the T-test (d = −2.9), 20-m sprint time (d = −2.0), DJ20 (d = 2.4), DJ40 (d = 2.0), THT (d = 1.9), RSAbest (d = −1.9), and the RSAtotal (d = −1.9) in the PJTG compared with CONG. Eight weeks of an in-season PJT in addition to regular soccer-specific training induced larger increases in measures of physical fitness in prepuberal male soccer players compared with regular soccer-specific training only. More specifically, PJT was effective in improving RSA performance.

BECAUSE OF RECENT DEMOGRAPHIC CHANGES WITH A GREATER PROPORTION OF ELDERLY PEOPLE IN THE WORLD, PHYSICAL INDEPENDENCE AMONG OLDER ADULTS IS BECOMING INCREASINGLY MORE IMPORTANT. THIS MINIREVIEW SUMMARIZES AND DISCUSSES NEUROMUSCULAR ADAPTATIONS IN RESPONSE TO RESISTANCE TRAINING WITH DIFFERENT CONTRACTION VELOCITIES IN UNTRAINED ELDERLY. SLOW AND FAST VELOCITY TRAINING CAN TO A SIMILAR EXTENT IMPROVE MUSCLE MASS AND MAXIMAL FORCE. HOWEVER, FAST VELOCITY RESISTANCE TRAINING IS SUPERIOR FOR IMPROVING POWER OUTPUT, EXPLOSIVE FORCE, AND FUNCTIONAL CAPACITY. THUS, FAST VELOCITY RESISTANCE TRAINING PROVIDES MORE EFFICIENT NEUROMUSCULAR ADAPTATIONS, INCREASING SIMULTANEOUSLY STRENGTH, POWER, EXPLOSIVE FORCE, MUSCLE MASS, AND FUNCTIONAL CAPACITY OF UNTRAINED ELDERLY.
