Mo’ Data, Mo’ Problems: Making Sense of Racial Discipline Disparities in a Large Diversifying Suburban High School
Authors: Irby Decoteau Jermaine
Published: April 2018

Purpose: This article explores the effects of sensemaking interventions on a group of educators’ race-conscious problem analysis of racial discipline disparities. Research Method: I conducted this research in a predominantly White diversifying suburban high school that served roughly1,600 students. To understand how sensemaking interventions shaped teachers’ racial ways of knowing, I conducted an ethnographic content analysis of 14 transcribed teacher focus group and data retreat exchanges to identify conversational patterns related to their problem framings. Findings: I found that providing diverse data types reflecting a range of racial perspectives offered cues that enabled organizational members to notice and (partially) disrupt the personal and organizational racism and race-evasive tendencies that drive the reproduction of racial inequities in school discipline. Implications for Research and Practice: Offering teachers sensemaking opportunities that prompt collective racial awareness and critical self-reflection can instigate shifts in racial ways of knowing that are critical to understanding and addressing discipline culture and climate problems in racially diversifying schools.
Remote Antimicrobial Stewardship: A Solution for Meeting The Joint Commission Stewardship Standard?
Authors: Howell C. K. , Jacob Jesse , Mok Steve
Published: April 2018

Purpose: The purpose of this study was to determine the time required for antimicrobial stewardship (AS) activities at a small community hospital (SCH) as well as barriers to remote AS to satisfy The Joint Commission (TJC)’s AS standard. Methods: This was a prospective chart review and time study conducted in patients identified by a clinical decision support application as potential opportunities for antimicrobial therapy modification at a SCH between December 12, 2016, and March 31, 2017. Potential interventions were communicated electronically to the clinical pharmacy specialist, who would then communicate the recommendations to the patient’s provider. The primary endpoint was a time study for stewardship activities. Secondary endpoints included describing barriers encountered to remote AS as well as a cost-benefit analysis of remote AS. Results: The time study revealed an average of 11 alerts per day, 9 chart reviews per day, 8 interventions per day, and 5 minutes per chart. Seven hundred twenty-four alerts were evaluated with the most common alerts constituting opportunities for de-escalation (29%), targeted drugs (22%), positive blood cultures (18%), Intravenous (IV) to oral (PO) (17%), and antimicrobial renal monitoring (8%).Interventions were accepted (11%), accepted modified (6%), rejected (35%), or undetermined (48%). Barriers to implementation included workflow and indirect communication. For patients with accepted interventions, there was an average savings of $279.82 per patient in pharmacy charges. Conclusion: Through remote AS, a SCH can have an antimicrobial stewardship program that is in compliance with the basic elements of the TJC standard MM.09.01.01, performs daily chart review by an infectious diseases trained pharmacist to increase the quality of patient care, and achieves a mean savings of $279.82 in pharmacy charges and $1,126.26 in hospital charges per patient with accepted interventions.
Scripture and Moral Examples in Pietism and Kant’s Religion
Authors: Head Jonathan
Published: April 2018

This paper argues for considerable Pietist influence upon Kant’s Religion within the Bounds of Mere Reason, through a focus upon the topics of Scripture and the use of moral examples within the context of a religious community. The recommended approaches to the use of Scripture in both Religion and the Pietist theology of Spener are compared, revealing deep parallels between Kant and core Pietist thought. In addition, the importance of moral examples in cultivating true, ‘moral faith’ is examined in both Kant and Pietism as a further major point of influence. The paper concludes by noting the potential significance of this Pietist influence for our wider understanding of Kant’s thought in the Critical period.
The Orthodox Church: Back to Progress
Authors: Maican Petre
Published: April 2018

There is an increased tendency inside the Orthodox Churches to reject the socio-cultural changes brought about by postmodernity and seek the restoration of an idealized past. In this article, I argue against this trend and set the premises for a constructive Orthodox engagement with secular postmodernity. Initially, I point out that in the patristic frame of thought, the movement of history receives a positive value as part of God’s plan to lead humankind to deification. In order to show how this motion towards deification can be discerned in a modern setting, I turn to Dumitru Stăniloae, who interpreted and applied the patristic vision of history in the context of communist Romania. Using Stăniloae’s criteria for evaluating the communist regime, I suggest that Orthodoxy and postmodernity might have more in common than what was initially thought and argue for a re-evaluation of the Orthodox approach to the major tropes of postmodernity.
Killing for God? Factional Violence on the Transnational Stage
Authors: Breslawski Jori , Ives Brandon
Published: April 2018

Why are some factions fighting for greater national self-determination (SD) more violent than others? While previous explanations of violence in these disputes have focused on the number of factions, their internal structures, and power distributions among factions, we find many factions that do not follow the expectations of these theories. In this article, we center on religious ideology, its unique transnational character, and the opportunity it creates for political elites from competing factions within the same SD movement to mobilize support. We argue that “religious factions” have a greater incentive to use violence than other factions. Violence serves as a costly signal, and it can be used to demonstrate a faction’s religious credentials to transnational networks and contacts, as they compete with each other on the international stage for the same potential benefactors. We code original data on the religious ideology of factions. We find that an increasing number of religious factions is associated with increased religious faction use of violence. Furthermore, our findings point to a critical insight: it is not religious ideology, but competition between religious factions, that generates violence.
The revolving door of reform
Authors: Tangen James , Briah Ravinderjit Kaur
Published: April 2018

Reform of probation services in England and Wales has been a frequent feature of its history, though the pace of review, restructuring and modification has increased exponentially in the last 30 years. This paper provides a brief history of changes to the National Probation Service since its inception in the Criminal Justice and Court Services Act 2000 to the recent announcements of the merger of prison and probation services into a new agency, Her Majesty’s Prison and Probation Service. Commonalities are identified between the various programmes of reform instigated throughout the last 17 years, drawing on insights from Pollitt. The paper addresses the implications for the future of a public probation service in England and Wales after the National Offender Management Service (NOMS) ceased to exist in April 2017 and Her Majesty’s Prison and Probation Service was inaugurated.

Introduction:

In case of pelvic recurrence of colorectal cancer, reirradiation of previously irradiated patients may increase the rate of salvage radical resection. Due to the high cumulative dose, one of the main concerns is radiation-induced lumbosacral plexopathy. This report describes multiple irradiations of a lesion adjacent to the lumbosacral plexus, using a highly selective technique, which allows optimal sparing of such a critical structure.

Case description

A 53-year-old woman treated in 2008 for a locally advanced rectal adenocarcinoma with preoperative pelvic irradiation and concomitant chemotherapy followed by surgery had disease recurrence in 2011 and underwent a second course of pelvic radiotherapy. In December 2015, magnetic resonance imaging showed a single local recurrence infiltrating the muscle next to the right lumbosacral plexus and close to the cauda equina. Repeat reirradiation was planned. The total dose deriving from the previous treatment plans was assessed by nonrigid image registration using the dedicated tool implemented in MIM 6.1.7 (MIMvista Corp., Cleveland, OH). The treatment was performed with Cyberknife (Accuray, Sunnyvale, CA) with a schedule of 20 Gy in 5 fractions (4 Gy per fraction). The dose was prescribed to 70% isodose and target coverage was 97%. Two months after the treatment, magnetic resonance imaging showed a decreased signal and stable disease with no change in tumor size.

Conclusions

This case report suggests that pelvic re-reirradiation might be a possibility in very carefully selected cases of rectal cancer, using high-precision radiation modalities.

Published: April 2018

Introduction

This study examines the validity and distribution characteristics of the PROMIS® pediatric upper limb measures in a sample of young people with cerebral palsy.

Method

Data are a cross-sectional subset of a larger prospective study of the responsiveness to change of PROMIS® pediatric measures following surgery to improve functioning in young people with cerebral palsy. Ninety-three participants between the ages of eight and 21 years completed the PROMIS® pediatric mobility and upper limb computer adaptive tests and short forms in conjunction with a set of static “legacy” measures of physical functioning, including a parent-report of upper limb function.

Results

The PROMIS® Pediatric upper limb short form demonstrated acceptable internal consistency (Cronbach’s alpha = 0.85). PROMIS® pediatric upper limb computer adaptive tests and short form mean values (42.1(11) and 43(10.4), respectively) were nearly 1 SD below normal, which is appropriate when a generic measure is used in a sample of young persons with cerebral palsy. The PROMIS® pediatric upper limb computer adaptive tests had a higher frequency of ceiling effects (29.50%) compared to the short form (18.30%).

Conclusion

Results of this study suggest that the PROMIS® pediatric upper limb computer adaptive tests and the short form are valid indicators of upper limb function in young people with cerebral palsy. The item bank can be replenished to address ceiling effects.
Bridge over Troubled Waters: Psalm 147
Authors: Schwartz Sarah
Published: April 2018

This article discusses the meaning of Psalm 147 in light of its literary structure, which is created by the repetition of similar elements in an identical order in each of the three stanzas. While this structure contributes to the literary cohesion of the psalm, it also emphasizes the differences between the stanzas, highlighting the divergent nature of the second stanza, and the nuanced thematic differences between the first and third stanzas. The literary analysis of each of the stanzas and the relationship between them leads to the conclusion that Psalm 147 expresses a balance between the conditional and the unconditional perceptions of redemption, and between nationalism and universalism. These perceptions are generally viewed as contradictory, and the balance suggested in Psalm 147 reflects a unique voice in Second Temple literature, as a conceptual bridge over troubled waters.
‘Eating Sex’ and the Unlovely Song of Songs: Reading Consumption, Excretion and D.H. Lawrence
Authors: Meredith Christopher
Published: April 2018

Recent trends in Song of Songs scholarship have questioned the obviousness of the so-called literal readings of the poem. This article contributes to that debate by returning to the poem's foodstuffs. Exploiting the idea of critical excrementality (Probyn, Châtelet, Kristeva), this study explores the way the ‘romantic’ Song of Songs tacitly relies on a politics of atrophy and excrementa. It argues that D.H. Lawrence anticipates the idea of an abject Song of Songs in his collection Birds, Beasts and Flowers. There, Lawrence exposes the unsettling preconditions of so-called romantic reading itself and sends us back to the Song with a sense that the poetic and the romantic are inherently excremental transactions.
Safety Evaluation of Cross-Sectional Elements of Freeway Managed Lanes
Authors: Avelar Raul E. , Fitzpatrick Kay
Published: April 2018

This paper investigated the safety implications of managed-lane cross-sectional elements. The objective of the Federal Highway Administration project was to investigate the relationship between crashes and buffer-separated managed lane dimensions. The results from several previous research studies have demonstrated that reductions in freeway lane width or shoulder width are associated with more crashes. This research found that a narrower managed-lane envelope width (i.e., left shoulder, managed-lane, and buffer width combined) is also associated with more freeway crashes for crashes of all severity levels including fatal and injury. Wider envelopes are associated a reduction in total freeway crashes, of all severities, of 2.8% in Texas, and 2.0% in California, for each additional foot of envelope width. In California, wider envelopes are associated with a reduction of 4.4% in managed-lane-related crashes resulting in fatalities and injuries at all severity levels, for each additional foot of envelope width. The analysis was conducted on nonweaving managed-lane segments that included a single managed-lane separated from the general-purpose lanes with a flush buffer area. The dataset included crashes on 128.0 miles of freeway in California (all 128.0 miles with flush buffers) and 60.4 miles of freeway in Texas (41.7 miles with pylon buffers and 18.7 miles with flush buffers). The California sites included freeways with three or four general-purpose lanes, and the Texas freeways had three to five general-purpose lanes.
A Revolution in a Revolution: The Secret Police and the Origins of Stalinism in Czechoslovakia
Authors: Pucci Molly
Published: April 2018

This article examines the origins of the Stalinist secret police force, the StB, in Czechoslovakia between 1945 and 1954. By focusing on the biographies of its officials, it argues that there was not one, but two, secret police forces in this period, each recruited from a different “generation” of local communists. In pointing to the social conflicts and ideological tensions that characterized the communist secret police force in this period, it forwards a new interpretation of the party purges and motivations of secret police officials responsible for the radical political violence in Stalinist Europe in the early 1950s.
The Benefits of Backlash: EU Accession and the Organization of LGBT Activism in Postcommunist Poland and the Czech Republic
Authors: O’Dwyer Conor
Published: April 2018

How can we explain variation in the organization of LGBT activism in postcommunist Europe, both across countries and over time? Much of the extant scholarship has analyzed the comparative politics of homosexuality in the region in terms of transnational norm diffusion occurring within the context of EU accession and integration. Thus, it emphasizes the empowerment of domestic gay rights groups either through maximizing the leverage of their external allies or through increasing their linkage with transnational advocacy networks. This paper argues that the effectiveness of these diffusion mechanisms is strongly constrained by the collective action problems faced by gay rights activists in societies with a legacy of civil society underdevelopment, such as in postcommunist Europe. We argue that hard-right backlash is a critical domestic factor that can help overcome these collective action problems, enabling gay rights activists to find resonant frames, build internal solidarity, and win allies—even when social movement resources are minimal. The research focuses on a close comparison of Poland and the Czech Republic since 1989 and draws on field interviews and original sources to process-trace the resonance of LGBT rights frames and how activism is organized. By building organizationally robust activism, postcommunist gay rights movements lay claim to full membership in the political community, exercise civil rights as LGBT citizens (not merely as private ones), and expand the sphere of “sexual citizenship.”
Prevalence of Mycoplasma genitalium and mutations associated with macrolide and fluoroquinolone resistance in Finland

Published: April 2018

The aim was to examine the prevalence of Mycoplasma genitalium and to determine the prevalence of mutations leading to resistance to macrolides and fluoroquinolones in a sexually transmitted infection clinic setting in Finland, and as a service evaluation, to validate the performance of a commercial Aptima® Mycoplasma genitalium assay. Urogenital samples were studied for M. genitalium with an automated commercial Aptima® Mycoplasma genitalium assay on the Panther® system (Hologic), and with an in-house real-time polymerase chain reaction (PCR) (mgpB). Positive specimens were further studied for mutations associated with macrolide resistance within the 23S rRNA gene and the known quinolone resistance-determining regions within genes gyrA, gyrB and parC. Altogether 17/303 (5.6%) of samples contained M. genitalium by either test. Two of the samples positive by the Aptima assay were not detected by the in-house PCR assay, although the internal control (beta-globin gene) was amplified. The Aptima assay gave an invalid result for five samples, all of which were negative by the in-house PCR. Mutations resulting in macrolide resistance were detected in 30.8% of M. genitalium-positive specimens. Prevalence of M. genitalium infections in the specimens tested is similar to that in other parts of Europe, 5.6%. The Aptima® Mycoplasma genitalium assay detected slightly more positives than the in-house PCR assay. Mutations resulting in macrolide resistance were common in M. genitalium and detection of these mutations is recommended in diagnostic laboratories to assist in selection of treatment.
A Qualitative Study Exploring Perceptions of Patients With Gout
Authors: Seow Li Ling , Jiao Nana , Wang Wenru , Holroyd Eleanor , Teng Gim Gee , He Hong-Gu
Published: April 2018

Gout is a chronic disease that is on a rising trend and greatly affects one’s physical and psychosocial well-being. The aim of this study was to explore patients’ perceptions of living with gout. A descriptive qualitative study was conducted and 15 adults with gout were interviewed face-to-face between December 2014 and January 2015. Thematic analysis was used to analyze the transcribed data. The experiences of patients with gout were found to revolve around four themes: emotional experiences with gout, disruptions in daily lives, interactions with doctor, and coping with gout using internal and external resources. The in-depth understanding of the patients’ experiences indicates a need to provide holistic patient education and to involve family members to create nurse-led support groups and to raise public awareness regarding gout.

This epilogue unpacks the return of convicted war criminals as homecomings, with all the attendant rites, rituals, and expectations. Knotting together the various papers in this edited collection, this paper examines how the international community constructs an ideal homecoming and, in turn, how such a construction may simply be fanciful.
The Media Negotiations of War Criminals and Their Memoirs
Authors: Ristić Katarina
Published: April 2018

The literature on transitional justice in former Yugoslavia holds that the International Criminal Tribunal for the former Yugoslavia (ICTY) proceedings, meant to establish the facts about the past, punish the perpetrators of mass violence, and even facilitate reconciliation, have led to the unexpected transformation of convicted war criminals into heroes in their home countries. Drawing on cultural criminology, the article looks at the phenomenon of “criminal celebrity,” which emerges at the juncture between public personality, intensive media attention, and high audience resonance. Considering that this transformation largely depends on the ability of different actors, including the convicts themselves, to create socially acceptable public personalities by reframing crimes, and their contexts and perpetrators, this article looks at the attempts to create such alternative accounts in the memoirs of the convicts, and in the media. This article argues that the mediation of war criminals in the ICTY facilitated a new type of criminal celebrity—the “ICTY celebrity,” who emerges from his/her relation to an allegedly unjust legal authority, rather than to the crimes. The ICTY celebrity is not a hero, known for heroic deeds or achievements—instead, his main function is to represent a flattering and consoling narrative about the past, enabling wide identification within the ethnic community.
Couples in Love
Authors: Meyer Dixie , Barkley Stephanie , Cohn Aaron , Salas Joanne
Published: April 2018

Counselors may be unaware of the physiological underpinnings of couple relationships. Understanding emotions as physiological responses resulting from autonomic arousal, we measured couples’ heart rate across a series of typical conversations. Forty-nine heterosexual and one lesbian couple completed measures of emotional reactivity and dyadic adjustment. We used pulse oximetry to record individual heart rate through three 5-min conversations. Using multilevel dyadic growth models, we found emotional arousal and reactivity-predicted heart rate among women, and greater relationship length predicted heart rate among men. We additionally found couples synchronous with respect to relationship satisfaction and emotional reactivity but not to physiological responsivity. This study contributes to counselors’ understanding of women’s physiological reactivity, male responses in longer relationships, and how to support couples when there is potential for relationship conflict.
Introduction: Just Say No? New Insights About Change Versus Constancy in Substance Use Behavioral Decisions in Youth With and Without ADHD
Authors: Jensen Peter S. , Weisner Thomas , Hinshaw Stephen P.
Published: April 2018

Despite enormous social-psychological and economic consequences of substance abuse in youth and young adults, too little is known about effective interventions among substance users, both with and without ADHD. This special issue reports on four linked investigations that employed a novel research strategy when the Multimodal Treatment Children with ADHD Study (MTA) participants were between ages 21.7 and 27.3 years old (14-16 years after initial assessments). Using combination of in-depth qualitative narrative interviews and quantitative analyses (“mixed methods”) of 183 participants from four to six original MTA sites, investigators sought to obtain a more complete understanding of factors contributing to youths’ substance use (SU) initiation, maintenance, and desistence, (both among youth with ADHD and control participants). The articles in this special issue illuminate important new insights about possible influences contributing to SU, particularly persistent use/abuse. Findings also illustrate the benefits of mixed-methods studies, not only to better understand the linkages between ADHD and SU, but also to understand other areas of child/adult psychopathology.
Simply waltzing on? Reflections on the performance of the Canberra Press Gallery in an era of prime-ministerial instability
Authors: Simons Margaret , Strangio Paul
Published: April 2018

This article draws on interviews with members of the Canberra Press Gallery to reflect on the performance of journalists in reporting recent national leadership instability. This is in the context of claims that reporters assisted in fomenting the instability and were ethically compromised. The increased pace of the news media cycle and the role of social media has caused a ‘cacophonous’ environment which journalist believe contributes to instability. The journalistic convention of background briefings is both central to the gallery’s performance in reporting leadership tensions and the major impediment to an informed assessment of whether journalists have assisted in fanning instability. We find that despite the centrality of the background briefing to the Gallery’s work, there is complexity and disagreement about the practice and the ethical standards that apply. This, we suggest, will be of increasing importance, yet the gallery’s willingness and ability to reflect on the issues is limited.
Politics and the media in Australia and the United Kingdom: parallels and contrasts
Authors: Gaber Ivor , Tiffen Rodney
Published: April 2018

Australia and Britain share many common aspects in their democratic political and media systems, but there are also important differences. Perhaps the single most important media difference is that television has been a much more important element in the UK political communication system than it has been in Australia. The British Broadcasting Corporation is a much bigger and more central institution than the Australian Broadcasting Corporation, and commercial TV in Britain has a much stronger public service mandate. The British press has a national structure which can give it a substantive collective role, although its right-wing dominance means it has been a less-than-benign influence on public life. Both countries are facing rapid changes, with partisan political divisions in flux and the digital environment disrupting traditional media models. In this article, we seek to interrogate the commonalities and differences between the media and political systems operating in Australia and the United Kingdom. After tracing some important differences in their institutional structures, the dominant theme of our later analysis is that in both systems, and in both countries, the overarching narrative is one of disruption. And we pose the question – Will the current disruptions widen or narrow these differences?
Serving time: Organization and the affective dimension of time
Authors: Johnsen Rasmus , Berg Johansen Christina , Toyoki Sammy
Published: April 2018

In this article, we explore the affective dimension of human temporality. Drawing on the work of Michael Theunissen in his Negative Theologie der Zeit (Negative Theology of Time), we suggest that understanding time as affect may help shed light on how people in organizational settings are influenced by and react toward time, once it comes to appear as an obstacle, rather than a resource to the unfolding of life. To capture such situations, we introduce the notion of ‘chronopathic experience’ and proceed to explore such experiences empirically among men incarcerated in Helsinki Prison. Here, we identify chronotelic behavior as a modality of activities directed toward dealing with the affective pressure exerted by time, as it comes to appear given, external, and meaningless. We argue that the affective dimension of human temporality can be drawn upon in other organizational contexts to clarify the notion of time pressure and to better understand temporality-related institutional pathologies like stress, boredom, and depression.
Prediction of the response of secondary structures under dynamic loading considering primary–secondary structure interaction
Authors: Lim Ellys , Chouw Nawawi
Published: April 2018

In current seismic design, earthquake-induced forces in secondary structures are estimated from the acceleration of the primary structure at the support of the secondary structure. However, recent studies had shown that the response of the secondary structure can significantly affect that of the primary structure, which will simultaneously modifies that of the secondary structure. To accurately estimate the response of the secondary structure, the interaction at the interface of the two structures needs to be considered. In this study, a scaled model consisting of primary and secondary structures was designed to capture the interacting forces. The degree of fixity of the secondary structure was varied. Two types of dynamic loading, that is, impact and harmonic loads, were applied to the model structures. The relationship between the interacting force and the response of the secondary structure is discussed. Empirical formulae for predicting the maximum displacement of the secondary structure based on the displacement spectrum at its base were proposed. The formulae provided more accurate prediction of the top displacement of the secondary structure considered, in comparison with that obtained from a conventional floor response spectrum.
Road-to-rig-to-desktop: Virtual development using real-time engine modelling and powertrain co-simulation
Authors: Andert Jakob , Xia Feihong , Klein Serge , Guse Daniel , Savelsberg Rene , Tharmakulasingam Raul , Thewes Matthias , Scharf Johannes
Published: April 2018

By front-loading of the conventional vehicle testing to engine test bench or even further forward to offline simulations, it is possible to assess a large variation of powertrain design parameters and testing manoeuvres in the early development stages. This entails a substantial cost reduction compared to physical vehicle testing and hence an optimisation of the modern powertrain development process. This approach is often referred to as road-to-rig-to-desktop. To demonstrate the potential of this road-to-rig-to-desktop methodology as a seamless development process, a crank angle–resolved real-time engine model for a turbocharged gasoline engine was built with the simulation tool GT-POWER®. The model was validated with measurement data from an engine test bench and integrated into a vehicle co-simulation, which also includes a dual clutch transmission, the chassis, the environment and the automated driver. The most relevant functions of the engine and the transmission control systems were implemented in a Simulink-based software control unit. To verify the engine model in the transient vehicle simulation, two 900-s time windows from a 2-h real driving emission test, representing urban and motorway conditions, are simulated using the developed co-simulation platform. The simulation results are compared with the respective vehicle measurement data. The fuel consumption deviation caused by the combustion engine model is within 5%. The transient system behaviour and the dominant engine operation points could be predicted with a satisfying accuracy.
Newness and human disclosure in Dewey and Arendt: Challenging neoliberal educational agenda
Authors: d’Agnese Vasco
Published: April 2018

Over the past decades, a neoliberal shift in educational policies has affected educational purposes and schooling practices worldwide and has reframed all of the features of education. From curriculum to teaching methods, from families and students’ perceptions regarding what is worthwhile and what is not to teachers’ professionalism, all aspects of education have been, de facto, deeply transformed by the neoliberal agenda for education. This paper draws on Dewey and Arendt to explore the interplay between the Deweyan call for “a new birth in the world” and the Arendtian questions of “new beginning” and “natality.” It is my contention that such an interplay may furnish a cue for a different conception of education and schooling. In this conception, under the regulation of teachers, the space of not-yet—that is, the space of pure potentiality for growth—may emerge in classroom activities, and new forms of meanings may arise.
Influence of designs of weaves on acoustic attenuation of fabrics
Authors: Barburski Marcin , Blaszczak Jarosław R , Pawliczak Zbigniew
Published: April 2018

The results of acoustics tests of different structure woven fabrics are presented. The researches were performed in the aeroacoustic anechoic chamber. Ten fabrics were tested (four of them with honeycomb 3D design) to check their acoustic properties. The tests were conducted inside lower and medium acoustical frequency zones. The presented studies showed that all fabrics with honeycomb weaves had much less attenuation than other fabrics, mostly due to less dense structures at higher thicknesses and more open internal structures. Having analyzed the obtained results, some comments are shown and possibilities of using such woven structures are proposed.
Numerical statistical analysis on self-organizing behavior of microfracturing events in rock failure
Authors: Zhang Houquan , Shi Hao , Wu Yu , Pu Hai
Published: April 2018

Current experimental investigations on microfracturing (or acoustic emission) events mainly focus on their location and distribution. A new function in rock failure process analysis (RFPA2D) code was developed to capture the size and number of damage element groups in each loading step. The rock failure process evolving from the initiation, propagation, and nucleation of microcracks was visually simulated by RFPA2Din this research. Based on the newly developed function, the statistical quantitative analysis of microfracturing events in rock was effectively conducted. The results show that microfracturing (failed element) events in the whole failure process accord with negative power law distribution, showing fractal features. When approaching a self-organized criticality state, the power exponent does not vary drastically, which ranges around 1.5 approximately. The power exponent decreases correspondingly as the stress increases. Through the analysis of the frequency and size of damaged element groups by rescaled range analysis method, the time series of microfracturing events exhibits the self-similar scale-invariant properties. Through the analysis by the correlation function method, the absolute value of the self-correlation coefficient of microfracturing sequence demonstrates a subsequent precursory increase after a long time delay, exhibiting long-range correlation characteristics. These fractal configuration and long-range correlations are two fingerprints of self-organized criticality, which indicates the occurrence of self-organized criticality in rock failure. Compared with the limited in situ monitoring data, this simulation can supply more sufficient information for the prediction of unstable failure and good understanding of the failure mechanism.
An isogeometric Reissner–Mindlin shell element based on mixed grid
Authors: Lei Zhen , Gillot Frederic , Jezequel Louis
Published: April 2018

We propose in this article a new isogeometric Reissner–Mindlin degenerated shell element for linear analysis. It is based on the mixed use of non-uniform rational basis spline and Lagrange basis functions in the same domain. The mid-surface of the shell is represented and discretized using non-uniform rational basis spline and the directors of the shell are discretized using Lagrange polynomials. The interpolatory property of Lagrange polynomials gives a natural choice of fiber vectors, thus removing the difficulties in the definition of directors that is seen in most isogeometric Reissner–Mindlin shell elements. The non-uniform rational basis spline representation of the mid-surface allows us to maintain the exact geometry representation characteristic of the isogeometric approach. The independent expressions of displacements and rotations also give users the possibility to use different numbers of degrees of freedom in an element for both kinematic variables. Several numerical examples show that our method is simple, robust, and efficient.
Performance of accelerated oscillator dampers under seismic loading
Authors: Tan Yonggang , Guan Ruyi , Zhang Zhe
Published: April 2018

Structure control techniques have been used to control vibrations in civil structures from natural and other types of hazards for many years. However, it is difficult to achieve effective reduction in the dynamic responses of the structures under seismic excitation for the reason that earthquake generates huge kinetic energy in short time interval, unless adopting very large conventional vibration reduction devices to absorb so much energy. A kind of mass damper, the accelerated oscillator damper is proposed in this article to improve the performance of vibration absorbers. The kinetic energy of the secondary mass is proportional to the square of its velocity, and speed of the secondary mass can be amplified through the transmission of the accelerated oscillator damper system, so that according to the principle of energy conservation, the more kinetic energy the secondary mass gets from the whole system, the more kinetic energy the building will lose. The proposed accelerated oscillator damper system is superior to the tuned mass damper system for short input durations and the maximum seismic response. Moreover, the investigation also shows that the transmission ratio plays a more significant role for vibration absorption than the mass ratio.
Fracture analysis and improvement of the main shaft of wind turbine based on finite element method
Authors: Wang Ruiming , Han Tian , Wang Wenrui , Xue Yang , Fu Deyi
Published: April 2018

For the main shaft of wind turbine of certain type, shaft fracture occurs at the variable section of the shaft during early stage of operation. In order to validate the failure analysis, finite element analysis of the main shaft was performed. The analysis results demonstrate that there is a severe stress concentration that leads to the formation of initial cracks at variable inner diameters of the main shaft. Also, the stress in the variable part mainly resulted in the pressure of the bulging joining sleeve applied on the main shaft via the gearbox planet carrier shaft. According to the above analysis, local structure improvements were carried out through increasing the action area between the bulging joining sleeve and the main shaft. The finite element simulation results show that the stress concentration in the variable section of the improved shaft decreases significantly. The improvement of shaft strength decreases the possibility of crack formation and its growth, thus enhancing the reliability of the main shaft. This analysis process and the results of this study can provide a reference in shaft fracture analysis and also technical support for improvement in the design of wind turbine main shafts.

The tail driving system based on linear hypocycloid has the advantages of adjustable phase difference, no quick-return, and combining speed reducer with transformation mechanism. The two-joint composite motion of the driving system was realized via caudal peduncle’s linear reciprocating in cosine and caudal fin’s oscillating in sine-like. First, dynamic and hydrodynamic models were established with momentum theorem, Lagrange theorem, and two-dimensional Foil theory. Second, study on lift force and vortex ring with optimal results was further conducted by numerical simulation in FLUENT. At last, theoretical derivation and simulation results have been testified in experiments.

Brain–computer interfaces are emerging as an important research area and are intended to create an understanding between a computer and the human brain to ensure that robot–human interactions become more intuitive and user-friendly. However, encoding of brain information to derive the intended motion of the user in real time continues to present a problem with respect to the control of wearable robots with multiple degrees of freedom. In this study, a new approach to control several degrees of freedom in a wearable robot is proposed and its feasibility is studied by estimating the user’s motion intention in real time, in terms of the user’s intended tasks to perform, by using electroencephalography signals measured from the scalp of the user. A time-delayed feature matrix is introduced to provide inputs to neural network and support vector machine-based classifiers that harvest the dynamic nature of the electroencephalography signals for motion intention prediction. The experimental results indicate the effectiveness of the proposed methodology in the estimation of user motion intention, in terms of intended task to perform.

This study aimed to analyze the characteristics of injuries and illnesses that occurred during the Rio 2016 Olympic Games for Korean team by using a prospective cohort design. In total, 204 Korean athletes competed in 24 sporting events during the Olympic Games. The entire medical staff of the Korean team recorded injuries and illnesses on a daily basis that occurred during training and competition using the International Olympic Committee injury and illness surveillance system. During the Olympic Games, 308 injuries and 73 illnesses were reported; the incidence was 150.9 injuries and 35.8 illnesses per 100 athletes. In addition, 56.3% and 24.0% of all athletes sustained at least one injury or illness, respectively. The highest rate of injuries was observed in boxing and wrestling, whereas the highest rate of illnesses was seen in boxing and swimming. Twelve percent of all injuries resulted in absenteeism from training or competition for at least 1 day. Of all infections, 75.9% occurred in the respiratory tract. In addition, 2.7% of all illnesses prevented athletes performing their sport for 1 day. These results may be used to further analyze mechanisms of injury and their risk factors in Olympic sports to develop effective preventive strategies for athletes.

US Army soldiers diagnosed with type 1 diabetes were previously considered unfit for duty. For highly motivated soldiers, current advanced technologies allow the possibility of not only retention on active duty, but military deployment. We present our experience at Fort Bragg, North Carolina, taking care of soldiers newly diagnosed with type 1 diabetes mellitus. Through intensive diabetes education, extensive military and physical training, optimization of diabetes technology, and remote real-time monitoring, soldiers are able to continue to serve their country in the most specialized roles.

The behavioral variant of frontotemporal dementia is usually a sporadic and progressive neurodegenerative disorder. Here, we report the subacute onset of a frontotemporal dementia phenotype with a treatable etiology. The patient has a history of rheumatoid arthritis, episcleritis, and thyroid eye disease on immunosuppressive therapy. He experienced a rapid personality change, including inappropriate behavior, which suggested frontotemporal dementia. Results of imaging and neuropsychological testing also suggested frontotemporal dementia. Because of his autoimmune diseases and unusually short onset of symptoms, serum paraneoplastic panel and cerebrospinal fluid were analyzed and revealed elevated P/Q- and N-type calcium channel antibodies. Treatment with therapeutic plasma exchange resulted in a rapid improvement of his behavior and cognition. This case suggests that there may be some treatable causes of frontotemporal dementia symptomatology, that is, paraneoplastic antibodies. In the context of atypical features of frontotemporal dementia, practitioners should maintain a high index of suspicion.
Four Critical Domains of Accountability for School Counselors

Published: April 2018

Despite recognition of accountability for school counselors, no clear set of interrelated performance measures exists to guide school counselors in collecting and evaluating data that relates to student academic success. This article outlines four critical domains of accountability for school counselors (i.e., grades, attendance, disciplinary referrals, and suspension) that can be generalized across primary and secondary levels, geography, region, location, and culture. The authors present a case study to demonstrate the four critical domains of accountability and establish school counselors as key players in promoting academic success.
Iloprost infusion through elastomeric pump in the treatment of Raynaud’s phenomenon and digital ulcers

Introduction:

Systemic sclerosis is a systemic autoimmune disease characterized by microangiopathy and fibroblast dysfunction resulting in fibrosis of the skin and internal organs. Raynaud’s phenomenon and digital ulcers are the main clinical features of vascular involvement. Treatment with iloprost is recommended to reduce the frequency and severity of Raynaud’s phenomenon attacks and to heal active digital ulcer. Classical forms of treatment require admission to a ward or day-hospital unit to ensure safety during infusion, causing disruption of the patient’s normal daily life and resulting in significant costs with hospitalization. Nowadays, new portable devices, of which the elastomeric pump is an example, are becoming available in order to avoid hospitalization.

Case reports:

We describe five cases of patients with systemic sclerosis or mixed connective tissue disease and severe Raynaud’s phenomenon/critical ischaemia or active digital ulcers that were successfully treated with iloprost infusion through elastomeric pump without experiencing any side effects. We present our unit’s protocol for ambulatory infusion.

Discussion/conclusion:

Our case reports and a brief review of literature prove that iloprost infusion through elastomeric pump is safe, easy and well tolerated and might even improve patient compliance with treatment. Meanwhile, it may also decrease the economic burden of hospitalization with these patients.
