Published: May 2017

In recent years, communication scholars have expressed concerns about the diversity of news media content. While we live in an era of ‘news abundance’ – the number of outlets and channels has increased enormously – the available news is argued to have become more of the same, but has it? As empirical evidence is lacking, this article verifies whether newspapers in Flanders (Belgium), over time, have indeed become less diverse in terms of the news stories they cover. Based on data from a longitudinal content analysis of nine Flemish newspapers at four points in time (1983, 1993, 2003, and 2013), it shows that (1) newspapers, in general, have not become more alike in terms of news stories; (2) newspapers with a similar profile (elite/popular) are less diverse than newspapers with dissimilar profiles; and (3) newspapers owned by the same media group (concentration of media ownership) are more alike than independently owned newspapers.
Quality Kilowatts: A Normative-Empirical Framework for Assessing TNC Performance on Sustainable Electricity Provision in Developing Countries
Authors: Wilde-Ramsing Joseph
Published: May 2017

The article develops a conceptual approach employing ‘modes’ of home-country business culture to evaluate how transnational corporations (TNCs) active in electricity provision in developing countries interpret and incorporate internationally recognised normative standards for ‘sustainable electricity provision’ (SEP) into their own corporate responsibility (CR) policies. Based on a survey of existing SEP norms, qualitative interviews with corporate managers, and analysis of CR materials, the article evaluates how ‘quality kilowatts’ are conceived and applied in three TNC case studies. The initial findings indicate that variations in how TNCs approach SEP reflect differences in regulatory framework and business culture of their countries of origin.

Published: May 2017

Introduction:

Percutaneous closure devices are commonly used to achieve hemostasis during endovascular procedures including transcatheter aortic valve implantation (TAVI). The aim of our study was to investigate the quality of the percutaneous femoral arterial closure by Prostar XL device using a systematic peroperative angiographic control at the end of TAVI procedure.

Materials and Methods:

Two hundred seventeen consecutive patients (mean age: 84 [6.5]; 112 women and 105 men) undergoing TAVI with percutaneous transfemoral access were prospectively registered in our center. Preoperative computed tomography scan was performed, and mean femoral vessel diameter was 7.9 (0.9) mm. At the end of TAVI intervention, the hemostasis was systematically achieved using the percutaneous closure device Prostar XL, without selection of patients based on anatomical criteria. An angiography with front and oblique views was performed to evaluate the quality and the safety of the closure device. Success of the percutaneous closure was defined as the absence of hemorrhage and the restitution of the arterial anatomy. Complications related to the percutaneous closure were classified as stenosis, dissection at the puncture site, suture failure, misplacement, or persistent bleeding.

Results:

Twenty-three (10.6%) patients had complications related to arterial percutaneous closure—14 (60.8%) stenosis, 6 (26.1%) persistent bleeding, and 1 (4.3%) dissection. These lesions were accessible to endovascular treatment via a crossover procedure. One (4.3%) suture failure and 1 (4.3%) misplacement of the device, with a puncture site created above the femoral arch, were reported. The patient developed a retroperitoneal hematoma postoperatively and required transfusion of 2 units of red blood cells associated with a cutdown to remove hematoma and to repair the common femoral artery.

Conclusion:

Angiography after arterial percutaneous closure using Prostar XL device during TAVI allows detection and endovascular treatment of vascular complications and is associated with low rate of conversion to open surgery.
The in situ construction of leader identity in a leader’s life story during an alumni talk to MBA students
Authors: Clifton Jonathan
Published: May 2017

Analysis of leaders’ life stories is widely regarded as a way of getting to the “just whatness” of leader identity. However, most research that makes use of leaders’ life stories considers the story to be a resource for investigating leader identity. Little, if any, research considers leaders’ life stories as a topic for research and investigates the in situ, context sensitive, interactional accomplishment of such stories. Using a video-recorded extract of an alumni talk to MBA students at an American business school, taking a social constructionist approach to identity, and using positioning theory as a methodology, the purpose of this paper is to reveal the “nitty gritty” of talking oneself into being as a “leader” through the in situ telling of a life story as a “leader’s” life story. Findings indicate that such a leader identity is constructed from a complex interplay of (1) characters in the storyworld, (2) the here-and-now interaction of the participants during the storytelling, and (3) wider societal Discourses of what is, and is not, an acceptable leader identity.
On the dynamic response of an instrumented headform for alternative mounting stiffnesses when subjected to ballistic impacts

Published: May 2017

The current British Standard for head protectors for cricketers has been recently revised to include a projectile-based battery of tests, the intention being to ensure that a certified helmet will also prevent contact of the ball or grille with the specified headform facial region. The purpose of this study was to characterise the dynamic response of the headform to direct ballistic impacts for alternative headform mounting arrangements. On one hand, and in accordance with the relevant sections of the Standard, what might be described as a ‘Constrained’ setup was evaluated while, on the other hand, an arrangement with significantly reduced stiffness, in line with that previously reported for the passive human neck, was subject to equivalent appraisal. For each mounting scenario, an air cannon was used to project a cricket training ball at three speeds towards the instrumented headform at three locations with five repeats per speed/location combination. High-rate/resolution video and piezoelectric accelerometer data were collected and processed to determine the headform response. While differences between specific ball impact speed and location scenarios are set out in detail later in the article, overall observations are summarised as follows. From a ball/headform contact duration standpoint, video derived results showed ranges of 1.30–1.45 ms (Constrained) versus 1.26–1.41 ms. Maximum ball deformations, the timing of which enabling the event to be subdivided into ‘loading’ and ‘unloading’ phases, were found to be 82.5%–86.2% (Constrained) versus 82.8%–86.4% of original ball diameter; mean peak headform accelerations during loading were found to be 860–1615 m/s2 (Constrained) versus 967–1638 m/s2; and headform speeds at the end of the loading phase were found to be 0.5–0.92 m/s (Constrained) versus 0.54–0.93 m/s. Differences between headform response for the two mounting arrangements were observed to be more substantial during the loading rather than unloading phase.
Experimental investigations of ion current in liquid-fuelled gas turbine combustors
Authors: Wollgarten J Christopher , Zarzalis Nikolaos , Turrini Fabio , Peschiulli Antonio
Published: May 2017

This work covers investigations of the static and dynamic behaviour of a confined, co-swirled and liquid-fuelled airblast injection system. The focus lies on the application of ion current sensors for the qualitative measurement of the heat release rate or for flame monitoring purposes in complex technical combustion processes. The ion current sensor is to operate in a feedback control loop in order to react on combustion dynamics in real time. The first part of the work analyses experimental data, which were obtained with different techniques, e.g. dynamic pressure, chemiluminescence, fine-wire thermocouples and ion current. The results show that the thermo-acoustic instability and the precessing vortex core generate an interaction mode. The frequency of this interaction mode is the difference of the other two modes. This has not yet been observed for partially premixed and liquid-fuelled injection systems before and also was not detected by the chemiluminescence of the flame. The ion current measurement technique is able to detect the helical mode of the precessing vortex core as well as the interaction frequency, leading to the conclusion that the chemical reactions are influenced by this helical structure. Contour maps of the frequencies reveal this influence in the outer shear layer. The second part of the study focused on the ion current probe as a method to predict static combustion instabilities, such as lean blowout. According to the results, the ion current is a fast responding method to detect lean blowout, provided that the detector is mounted at a suitable position. Measurements at different positions in the flame were compared with phase-locked chemiluminescence measurements. Precursors in the ion current signal for lean-blowout prediction were found using a statistical approach, which is based on ion peak distance. The precursor events allow for the use of this approach with a feedback control loop in future applications.
The Impact of Previous Athletic Experience on Current Physical Fitness in Former Collegiate Athletes and Noncollegiate Athletes
Authors: Simon Janet E. , Docherty Carrie L.
Published: May 2017

Background:

Physical activity performed at moderate intensity is associated with reduced risk of mortality, cardiovascular disease, hypertension, and some types of cancers. However, vigorous physical activity during participation in college athletics may increase the risk of injury, which might limit future physical activity levels.

Purpose:

To evaluate differences in current physical fitness levels between former Division I athletes and noncollegiate athletes.

Study Design:

Cross-sectional study.

Level of Evidence:

Level 3.

Methods:

The sample was recruited from a large midwestern university alumni database and consisted of 2 cohorts: (1) former Division I athletes (n = 100; mean age, 53.1 ± 7.4 years) and (2) nonathletes who were active in college (n = 100; age, 51.4 ± 7.3 years). Individuals answered a demographics questionnaire and completed a physical fitness assessment consisting of 7 measures: percent body fat, 1-mile walk, sit-to-stand test, push-up, half sit-up test, sit and reach test, and back scratch test.

Results:

Performance was significantly worse for former Division I athletes compared with nonathletes for percent body fat (mean difference, 7.58%; F(1, 198) = 59.91; P < 0.01), mile time (mean difference, 2.42 minutes; F(1, 198) = 1.74; P = 0.03), sit-to-stand test (mean difference, 4.3 repetitions; F(1, 198) = 6.59; P = 0.01), and push-up test (mean difference, 8.9 repetitions; F(1, 198) = 7.35; P = 0.01).

Conclusion:

Former Division I athletes may be limited because of previous injury, inhibiting their ability to stay active later in life.

Clinical Relevance:

It is imperative that clinicians, coaches, and strength and conditioning specialists understand the possible future repercussions from competing at the Division I level.
The Power of Projection for Powerless and Powerful People
Authors: Toma Claudia , Yzerbyt Vincent , Corneille Olivier , Demoulin Stéphanie
Published: May 2017

Past social projection research has mainly focused on target characteristics as a moderator of projective effects. The current research considers the power of the perceiver and how it affects projection of competence and warmth. In three studies, participants first rated themselves on a list of traits/preferences, then performed a power manipulation task, and, finally, rated a target person on the same list. Studies 1 and 2 reveal that the effect of power on social projection is moderated by dimension of judgment: high-power/low-power participants project more on competence/warmth than low-power/high-power participants. A meta-analysis conducted on Studies 1, 2, 3, and two additional studies confirmed those results. Study 3 additionally shows that high power increases the salience of competence, whereas low power increases the salience of warmth. Implications for both the power and the social perception literatures are discussed.

The capabilities offered to psychology researchers by new technology have catapulted the field toward a deeper understanding of people’s social experiences. However, it concurrently increases the need to consider the ethical and legal concerns of capturing information about bystanders. This article outlines the legal and ethical issues that researchers should consider when conducting social environment sampling research. The goal is to serve as a “quick start guide” to the unique legal and ethical challenges that arise with social environment sampling, and to offer some solutions.
Structural Segmentation of Toru Takemitsu’s Piece, Itinerant, by Advanced Level Music Graduate Students
Authors: Ordoñana Jose A. , Laucirica Ana
Published: May 2017

This work attempts to study the way higher music graduate students segment a contemporary music work, Itinerant, and to understand the influence of musical feature on segmentation. It attempts to test the theory stating that saliences contribute to organising the music surface. The 42 students listened to the work several times and, in real time, they were requested to indicate the places on the score where they perceived structural boundaries. This work is characterised by its linearity, which could hinder identification of saliences and thereby, the establishment of structural boundaries. The participants show stability in the points of segmentation chosen. The results show significant coincidences among the participants in strategic places of the work, which leads us to conclude, in line with other researches, although in a work with different characteristics, that listeners can find a structural organisation in contemporary music that could allow them to understand it.

Published: May 2017

Following the work of Evans, Cordova, and Sipole, we examine the way that candidates for congressional seats in 2014 used Twitter during the last 2 months of their campaign. Using a content analysis of every tweet sent by all candidates for both the US House and Senate, we show that particular individual-level and campaign-specific characteristics are related to whether and how often candidates go negative on Twitter. In particular, we show that there are differences based on competitiveness, incumbency, gender, and partisanship.
Encouraging Medicare Advantage Enrollees to Switch to Higher Quality Plans: Assessing the Effectiveness of a “Nudge” Letter

Published: May 2017

There are considerable quality differences across private Medicare Advantage insurance plans, so it is important that beneficiaries make informed choices. During open enrollment for the 2013 coverage year, the Centers for Medicare & Medicaid Services sent letters to beneficiaries enrolled in low-quality Medicare Advantage plans (i.e., plans rated less than 3 stars for at least 3 consecutive years by Medicare) explaining the stars and encouraging them to reexamine their choices. To understand the effectiveness of these low-cost, behavioral “nudge” letters, we used a beneficiary-level national retrospective cohort and performed multivariate regression analysis of plan selection during the 2013 open enrollment period among those enrolled in plans rated less than 3 stars. Our analysis controls for beneficiary demographic characteristics, health and health care spending risks, the availability of alternative higher rated plan options in their local market, and historical disenrollment rates from the plans. We compared the behaviors of those beneficiaries who received the nudge letters with those who enrolled in similar poorly rated plans but did not receive such letters. We found that beneficiaries who received the nudge letter were almost twice as likely (28.0% [95% confidence interval = 27.7%, 28.2%] vs. 15.3% [95% confidence interval = 15.1%, 15.5%]) to switch to a higher rated plan compared with those who did not receive the letter. White beneficiaries, healthier beneficiaries, and those residing in areas with more high-performing plan choices were more likely to switch plans in response to the nudge. Our findings highlight both the importance and efficacy of providing timely and actionable information to beneficiaries about quality in the insurance marketplace to facilitate informed and value-based coverage decisions.

Electronic cigarettes and lung toxicity
Authors: Rodrigues Terrance , Deal Eric , Nugent Kenneth , Payne J. Drew
Published: May 2017

The use of electronic cigarettes (e-cigarettes) in the United States has steadily increasedsince their introduction into the market in 2007. These devices deliver nicotine through thevaporization of a liquid which contains a vehicle (propylene glycol or glycerin), artificialflavoring, and nicotine. The combustion of these liquids creates a vapor containing particulates,multiple chemicals, and nicotine. The long-term safety of these products is unknown. Studiesin healthy, non-smoking volunteers and smokers with no clinical pulmonary disease havedemonstrated that the inhalation of e-cigarette vapor has minimal short-term effects onpulmonary function. The exposure of cell cultures to e-cigarette liquid or aerosols has beenshown to reduce cell viability, induce cytokine production, and cause oxidative stress. Theexposure of animals (mice and rats) to e-cigarette aerosols induces inflammatory responsesin the lungs and delays the clearance of bacterial and viral challenges. There are a smallnumber of case reports of patients developing acute pulmonary toxicity following the use ofe-cigarettes. Two patients have developed lipoid pneumonia following the use of e-cigarettesfor 3 and 7 months. Finally, several studies suggest that patients with chronic lung diseasewho switch from tobacco cigarettes to e-cigarettes can have improvement in lung function(asthmatics) and a reduction in the number of exacerbations (chronic obstructive pulmonarydisease). Clearly, the public and the medical profession need more information about thelong-term complications associated with the use of e-cigarettes and their benefit in smokingcessation efforts.Keywords: electronic
Anhydrous ammonia pulmonary toxicity: A significant farming hazard
Authors: Waheed Irfan , Fuller Audra
Published: May 2017

Anhydrous ammonia is a toxic gas widely used as a fertilizer. In 2016 about 12 milliontons of ammonia were used in the production of fertilizers. We are reporting a case of severepulmonary toxicity from anhydrous ammonia fertilizer exposure. An 80-year-old male farmerwas accidentally exposed to anhydrous ammonia released from a pressurized fertilizer tank.He was intubated due to upper airway inhalation injury. Bronchoscopy showed extensivelower airway mucosal damage. The sloughed bronchial mucosa was removed from obstructedbronchi using a cryoprobe. He developed acute respiratory distress managed with lungprotective mechanical ventilation. He did not improve and tracheostomy was recommended.The patient’s family opted for comfort care only. Anhydrous ammonia can cause pulmonarytoxicity. Symptoms range from mild to severe and can be fatal at doses greater than 5,000parts per million. Early inspection of the upper respiratory tract and securing an airway arelifesaving. Management is supportive with oxygen and mechanical ventilation. Education, theuse of protective gear, and proper equipment handling are key steps in the prevention ofaccidental toxicity.

Monitoring time after primary angioplasty for STEMI
Authors: Phuyal Urmila , Pottle Alison
Published: May 2017

The European Society of Cardiology (ESC) (2012) recommends that patients with ST-Segment elevation myocardial infarction (STEMI) should be monitored in a coronary care unit (CCU) for a minimum of 24 hours post primary percutaneous coronary intervention (PPCI). However, in practice, stable patients with complication-free PPCI are often stepped down earlier than the recommended 24 hours as a result of the increased demand on CCU beds. The aim of this audit was to establish optimum CCU monitoring time and the complication rate in this patient group within the 48 hours of PPCI. The audit shows that 37% of patients were stepped down from CCU earlier than the recommended period. All complications observed were minor and more than 50% of these occurred within the first 6 hours. The results demonstrated that a minimum of 24 hours of CCU monitoring is not mandatory and the length of CCU monitoring can be decided upon on an individual patient basis.
Accuracy of ultrasound, thermography and subepidermal moisture in predicting pressure ulcers: a systematic review
Authors: Oliveira A.L. , Moore Z. , O´Connor T. , Patton D.
Published: May 2017

Objective:

Our aims were to: establish the clinical significance of ultrasound, thermography, photography and subepidermal moisture (SEM) measurement; determine the accuracy of ultrasound, thermography, photography and SEM measurement in detecting skin/tissue damage; determine the relative accuracy of one of these assessment methods over another; make recommendations for practice pertaining to assessment of early skin/tissue damage.

Method:

The following databases, Cochrane Wounds Group Specialised Register, The Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Ovid EMBASE, Elsevier version, EBSCO CINAHL, ClinicalTrials.gov , WHO International Clinical Trials Registry (ICTR) and The EU Clinical Trials Register were searched for terms including; thermography, ultrasound, subepidermal moisture, photograph and pressure ulcer.

Results:

We identified four SEM, one thermography and five ultrasound studies for inclusion in this review. Data analysis indicated that photography was not a method which allowed for the early prediction of PU presence. SEM values increased with increasing tissue damage, with the sacrum and the heels being the most common anatomical locations for the development of erythema and stage I PUs. Thermography identified temperature changes in tissues and skin that may give an indication of early PU development; however the data were not sufficiently robust. Ultrasound detected pockets of fluid/oedema at different levels of the skin that were comparable with tissue damage. Thus, SEM and ultrasound were the best methods for allowing a more accurate assessment of early skin/tissue damage. Using the EBL Critical Appraisal Tool the overall validities of the studies varied between 33.3–55.6%, meaning that there is potential for bias within all the included studies. All of the studies were situated at level IV, V and VII of the evidence pyramid. Although the methodological quality of the studies warrants consideration, these studies showed the potential that SEM and ultrasound have in early PU detection.

Conclusion:

SEM and ultrasound are promising in the detection and prediction of early tissue damage and PU presence. However, these methods should be further studied to clarify their potential for use more widely in PU prevention strategies.
Clinical outcomes and cost-effectiveness of three different compression systems in newly-diagnosed venous leg ulcers in the UK
Authors: Guest J.F. , Fuller G.W. , Vowden P.
Published: May 2017

Objective:

To assess clinical outcomes and cost-effectiveness of using a two-layer cohesive compression bandage (TLCCB; Coban 2) compared with a two-layer compression system (TLCS; KTwo) and a four-layer compression system (FLCS; Profore) in treating newly-diagnosed venous leg ulcers (VLUs) in clinical practice in the UK, from the perspective of the NHS.

Method:

This was a retrospective cohort analysis of the case records of patients with newly-diagnosed VLUs randomly extracted from The Health Improvement Network (THIN) database (a nationally representative database of clinical practice among patients registered with general practitioners in the UK) who were treated with either TLCCB (n=200), TLCS (n=200) or FLCS (n=200). The clinical outcomes and cost-effectiveness of the alternative compression systems were estimated over six months after starting treatment.

Results:

Patients' mean age was 72 years and 58% were female. Time from wound onset to the start of compression was a mean of two months, and when starting compression the wound size was a mean of 45 cm2. The distribution of healing was significantly different between the three groups; 76% of wounds in the TLCCB group healed by six months compared with 70% and 64% in the TLCS and FLCS groups, respectively (p=0.006). Time to healing was significantly less in the TLCCB group compared with the two other groups (p=0.003). Patients in the TLCCB group experienced better health-related quality of life over six months (0.413 quality-adjusted life years (QALYs) per patient), compared with the TLCS and FLCS groups (0.404 and 0.396 QALYs per patient, respectively). The mean six-month NHS management cost was £3045, £3842 and £4480 per patient in the TLCCB, TLCS and FLCS groups, respectively.

Conclusion:

Real-world evidence demonstrates that treating newly-diagnosed VLUs with TLCCB, compared with the other two compression systems, affords a more cost-effective use of NHS-funded resources in clinical practice since it resulted in an increased healing rate, better health-related quality of life and a reduction in NHS management cost.
When borderlands are where we live: Disgrace (Jacobs, 2008), Invictus (Eastwood, 2009) and District 9 (Blomkamp, 2009)
Authors: Moya Ana
Published: May 2017

This article discusses the nature and role of borderlands in Disgrace (Jacobs, 2008), Invictus (Eastwood, 2008) and District 9 (Blomkamp, 2009). Though rape, a rugby team and a group of aliens are apparently very different points of departure for a story, the article proves how these films adapt a single tale of borderlands in postapartheid South Africa, elaborating on the plurality of angles from which such a story may be told. The article discusses the poetics of the border at work in these films and the ways in which they explore the border as a site of struggle. In this sense, the article proves the extent to which borderland theory offers the necessary critical frame for a fruitful discussion of these films with the border becoming a productive epistemic angle; a suitable method for the critical discussion of global passages of people, money or objects.

“It’s a big world in here”: Contemporary Voyage Drama and the Politics of Mobility
Authors: Wilkie Fiona
Published: May 2017

In Renaissance and Restoration England, many popular plays functioned as “voyage dramas,” offering opportunities for vicarious tourism to their audiences (McInnis 2012). The theatre became one site in which to receive and negotiate information about elsewhere, at a time before mass access to travel was available. The tagline of London’s Young Vic theatre – “It’s a big world in here” – suggests that something of this spirit survives in twenty-first-century performance. It is a sentiment that we find also in the festival director Mark Ball’s assertion that “theatre is my map of the world.” But the version of the world created here is necessarily skewed by a politics of mobility (Cresswell 2010): the uneven frictions, routes, speeds, levels of comfort, and power relations affecting how theatre-makers and productions move around the world. And contemporary audiences are themselves likely to come to the theatre with multiple and unequal experiences of travel. This article asks what function contemporary voyage dramas serve in a context of the widespread mobility of people, finance, goods and ideas, and what might be the political challenges of representing travel in the theatre. It investigates the claim to authenticity, the negotiation of privilege and remoteness, and the role of the performer as mediator in theatrical travel narratives. In particular, it focuses on Simon McBurney’s solo performance

The size prediction of potential inclusions embedded in the sub-surface of fused silica by damage morphology
Authors: Gao Xiang , Qiu Rong , Wang Kunpeng , Zhang Jiangmei , Zhou Guorui , Yao Ke , Jiang Yong , Zhou Qiang
Published: May 2017

A model for predicting the size ranges of different potential inclusions initiating damage on the surface of fused silica has been presented. This accounts for the heating of nanometric inclusions whose absorptivity is described based on Mie Theory. The depth profile of impurities has been measured by ICP-OES. By the measured temporal pulse profile on the surface of fused silica, the temperature and thermal stress has been calculated. Furthermore, considering the limit conditions of temperature and thermal stress strength for different damage morphologies, the size range of potential inclusions for fused silica is discussed.
Physical-chemical properties studying of molecular structures via topological index calculating

Published: May 2017

It’s revealed from the earlier researches that many physical-chemical properties depend heavily on the structure of corresponding moleculars. This fact provides us an approach to measure the physical-chemical characteristics of substances and materials. In our article, we report the eccentricity related indices of certain important molecular structures from mathematical standpoint. The eccentricity version indices of nanostar dendrimers are determined and the reverse eccentric connectivity index for V-phenylenic nanotorus is discussed. The conclusions we obtained mainly use the trick of distance computation and mathematical derivation, and the results can be applied in physics engineering.
Solipsism – The Leitmotif in Wittgenstein’s Life and Philosophy
Authors: Gabriel Gottfried
Published: May 2017

This paper will highlight the close relationship between Wittgenstein’s life and train of thought, using his treatment of solipsism as an example. The intensity with which Wittgenstein explored this theme hints towards an existential and cultural background that is further developed in a comparison of his works with the entries in his diaries. The treatment of solipsism will be presented as an expression of an inner wrestling for the correct view of world and life. The transition from early to late philosophical thought is paired with a revised understanding of the concept of a felicitous life, which in turn is reflected in an altered understanding of language. The replacement of an analysis of the general form of propositions by the description of language games and the departure from logical forms towards forms of life - from a practical point of view - corresponds with a new approach to overcoming alienation.

For a systematic assessment of Wittgenstein’s initial espousal of solipsism (in the Tractatus) and his later criticism (in the Philosophical Investigations), the various types of solipsism, which Wittgenstein used as benchmarks, will be taken into consideration, in particular, Weininger’s ethical solipsism, Schopenhauer’s contemplative aesthetic solipsism as well as Descartes’ methodological solipsism.
Wittgenstein’s Natural-Historical Investigations
Authors: Guetti Edward
Published: May 2017

In this essay I try to sketch the difficulties that face anyone writing about Wittgenstein’s later method. I then insist that an underappreciated remark of his be taken seriously: that his method be seen as natural-historical. There are several difficulties that result from taking this stance, and I believe I address each of them after developing a fuller picture of what a “natural-historical method” will mean (and here I am broadly following lines laid out by Michael Thompson). I conclude with literary examples (Sebald’s Austerlitz and his Rings of Saturn) in order to exemplify further the recuperative and fantasy-defeating potential of a natural-historical method akin to Wittgenstein’s.
„James’s book The Varieties of Religious Experience does me a lot of good.“
Authors: Nagl Ludwig
Published: May 2017

Wittgenstein zitiert in seinen Schriften nur wenige Autoren, den amerikanischen Pragmatisten William James bis in sein Spätwerk hinein jedoch mit auffallender Häufigkeit. Das hängt - so die Leitthese des Beitrags - vor allem mit der Rolle zusammen, die James‘ Erkundungen des Religiösen für Wittgensteins Nachdenken über Religion spielen. Der intrikaten Verbindung Wittgenstein-James wird in sieben Reflexionen nachgegangen: 1. Krisis der Lebenspraxis: „The Sick Soul“ (James, Tolstoi, Wittgenstein); 2. Das existentiell dimensionierte „Paradoxon“ als rektifizierte/dekonstruierte Dialektik? Wittgensteins (beredtes?) Schweigen im Tractatus; 3. Kann Reflexion stillgestellt werden? „Therapie“ als „Ende der Philosophie“? 4. Kritische Eindämmung des „Szientismus“: Wittgensteins und James‘ Einsprüche gegen die „survival theory of religion“; 5. Exkurs zum Jamesschen Thematisierungsversuch des „Mystischen“; 6. James und Wittgenstein über das „institutionalisierte“ Religiöse: „Religion - a matter between me and God only“? - „Subjektive“ Religiosität vs. „korporative“ Religion; 7. Coda. Die (innere) Ambivalenz religiöser Motivation: Sami Pihlströms (post‐) Wittgensteinsche Reflexionen.

Crystal structures are reported from data collected at 100 K of (E)-2-(X-benzylidene)-1-tetralone (2: X=3-O2N; 3: X=4-O2N; 5: X=4-HO; 6: X=4-Me2N; 7: 4-NC), (E)-2-(X-benzylidene)-6-MeO-1-tetralone, 8, and (E)-2-(X-benzylidene)-5-MeO-1-tetralone 9. Also reported herein are the Hirshfeld surface calculations for these compounds as well as those of (E)-2-(X-benzylidene)-1-tetralone (1: X=H; 4: X=4-MeO), whose structures were previously reported. The molecules are not planar as shown by the dihedral angles of 45.66(5)–69.78(5)° between the phenyl groups and by the puckered cyclohexenyl rings. A common feature of the molecular conformations is the C–H···O1(carbonyl) intramolecular hydrogen bond. The carbonyl oxygen atom plays significant roles in the interactions in all compounds baring compound 8. However, there is no consistent set of intermolecular interaction in this group of compounds. Intermolecular interactions present in each compound are some of the O–H···O, C–H···A (A=O, N or π), A–O···π (A=C or N) and π···π interactions. The only compound exhibiting a classical O–H···O hydrogen bond is compound 5. C–H···π interactions are found in all compounds, and while π···π interactions are present in compounds 2, 3, 7 and 9, no consistent type of stacking arrangement is shown. The Hirshfeld surface calculations, while generally concurring with the intermolecular interactions indicated by PLATON analyses, also reveal short interactions, which fall below the PLATON cut-off parameters.
Electron transfer-induced oxidation of 2,3-dihydroquinazolin-4(1H)-ones
Authors: Memarian Hamid Reza , Ghahremani Saeideh
Published: May 2017

A series of 2-substituted 2,3-dihydroquinazolin-4(1H)-ones were oxidized to quinazolin-4(3H)-ones using tetrabutylammonium peroxydisulfate. The rate and the outcome of the reaction are dependent on the type and nature of 2-substitution. An electron transfer mechanism is proposed for this study, which is supported by the retention or elimination of 2-substitution during the oxidation process.

Sun, M-Y, Lu, J-Q, Ma, Z-C, Lü, J-J, Huang, Q, Sun, Y-N, and Liü, Y. Effects of the inertia barbell training on lumbar muscle T2 relaxation time. J Strength Cond Res 34(12): 3454–3462, 2020—The purpose of this study was to investigate variations in T2 relaxation time in normal human lumbar muscles caused by inertia barbell training. Thirty undergraduate healthy men (mean age = 19 ± 1.2 years, body mass = 72 ± 10.0 kg, and height = 1.78 ± 0.1 m) were recruited to participate in this study. Subjects were randomly assigned into 2 groups: an inertia barbell training group (IBTG) (n = 15) and a normal barbell-training group (NBTG) (n = 15). All subjects participated in lumbar flexion and extension muscle strength training for 1 hour per time, 3 times per week for a total of 8 weeks. The lumbar area of each subject was scanned before and after the experiment using a 3.0T superconductive magnetic resonance imaging system. The T2 values measured after intervention were significantly different compared with the T2 values measured before the experiment in both the IBTG and NBTG groups (p < 0.001). After intervention, there was no significant difference in T2 values between the IBTG and NBTG groups (p = 0.17). The (∆T2)/T2 percentage was significantly different in the IBTG group (p < 0.01). This study demonstrated that 8 weeks of strength training led to significant improvements in the values for T2 relaxation time of the lumbar muscles. Furthermore, the (∆T2)/T2 percentage for IBTG was higher than that for NBTG, which suggested that lumbar muscle activity increased more with inertial barbell training.
Ladder Treadmill: A Method to Assess Locomotion in Cats with an Intact or Lesioned Spinal Cord

After lesions of the CNS, locomotor abilities of animals (mainly cats) are often assessed on a simple flat treadmill (FTM), which imposes little demands on supraspinal structures as is the case when walking on targets. Therefore, the aims of the present work were as follows: (1) to develop a treadmill allowing the assessment of locomotion of intact cats required to place the paws on the rungs of a moving ladder treadmill (LTM); (2) to assess the capability of cats after a unilateral spinal hemisection at T10 to cope with such a demanding locomotor task; and (3) to regularly train cats for 6 weeks on the LTM to determine whether such regular training improves locomotor recovery on the FTM. A significant improvement would indicate that LTM training maximizes the contribution of spinal locomotor circuits as well as remnant supraspinal inputs. Together, we used 9 cats (7 females, 2 males). Six were used to compare the EMG and kinematic locomotor characteristics during walking on the FTM and LTM. We found that the swing phase during LTM walking was slightly enhanced as well as some specific activity of knee flexor muscles. Fore-hindlimb coupling favored a more stable diagonal coupling. These 6 cats were then hemispinalized and trained for 6 weeks on the LTM, whereas the 3 other cats were hemispinalized and trained solely on the FTM to compare the two training regimens. Intensive LTM training after hemisection was found to change features of locomotion, such as the foot trajectory as well as diminished paw drag often observed after hemisection.

SIGNIFICANCE STATEMENTThis paper introduces a method (ladder treadmill [LTM]) to study the locomotor ability of cats with an intact spinal cord or after a unilateral hemisection to walk with a precise foot placement on the rungs fixed to an ordinary flat treadmill (FTM). Because cats are compared in various conditions (intact or hemisected at different time points) in the same enclosure on the FTM and the LTM, the changes in averaged locomotor characteristics must reflect the specificity of the task and the neurological states. Furthermore, the ladder treadmill permits to train cats repetitively for weeks and observe whether training regimens (FTM or LTM) can induce durable changes in the parameters of locomotion.
