Are UK music therapists talking past each other? A critical discourse analysis of three book reviews
Authors: Wetherick Donald
Published: September 2019

Ansdell’s ‘Winds of Change’ paper articulated a distinction in UK music therapy between established ‘consensus’ practice drawing on psychotherapeutic principles and developing or previously hidden ‘community music therapy’ practices based on ecological or social-psychological principles. Writing that addresses different theoretical positions in music therapy (meta-theory) exists from European and American perspectives but far less from a UK perspective. This article considers the view that UK music therapy writing in general has continued along one or other of these paths and that there has been relatively little exchange between them; indeed, that UK music therapists tend to ‘talk past each other’. To explore the matter systematically, this article takes a critical discourse analysis approach to analysing three recent music therapy book reviews. Critical discourse analysis was chosen to identify underlying assumptions (‘ideologies’) that shape thinking and practice, as revealed by language use. Book reviews were identified as texts where reviewers typically engage with authors from different perspectives and in doing so offer potentially rich material for such analysis. The analysis identifies ways in which UK music therapy writing shows signs of stress across a divide between ecological and psychodynamic approaches, with reviewers going to some lengths to reconnect these different positions and so unify a discourse within which ‘fault-lines’ are present. It is suggested that, in the United Kingdom at least, ecological and psychodynamic music therapy writing are becoming more separated as discourses, with a lack of integrated meta-theoretical discussion or examples of shared practice. This inhibits coherent development of the discipline and the effective training of future practitioners. A case is made for greater integration in music therapy writing through both developments in meta-theory and by practitioners sharing examples of cross-theoretical practice.
A hybrid ant lion optimizer with improved Nelder–Mead algorithm for structural damage detection by improving weighted trace lasso regularization
Authors: Chen Chengbin , Yu Ling
Published: September 2019

Structural damage detection is the kernel technique in deploying structural health monitoring. The structural damage–detection technique using heuristic algorithms has been developed at an astounding pace over the past years. However, some existing structural damage–detection methods are prone to easily fall into the local optimum and to be unstable when they are applied to complex structures. In order to make full use of advantages of heuristic algorithms and overcome abovementioned shortcomings, a hybrid algorithm, which combines the ant lion optimizer with an improved Nelder–Mead algorithm, is proposed to solve the constrained optimization problem of complex structural damage detection. First, an objective function is established for damage identification using structural modal parameters, that is, frequencies and mode shapes. The solution to the objective function is accurately attained by a newly improved weighted trace lasso which can improve the computing performance and stability of procedure and reduce randomness of weighted coefficients. After assessing the computing performance of the proposed hybrid algorithm using three classical mathematical benchmark functions, two structural damage–detection numerical simulations and a laboratory verification are then conducted to fully assess the structural damage–detection capability of the proposed method. Meanwhile, the equivalent element stiffness-reduction model is introduced to estimate the real damage severities of cracks which are created in laboratory structures and to compare with the structural damage–detection results by the proposed method. The illustrated results show that the proposed hybrid algorithm can locate damage and quantify damage severity more accurately and stably with a good robustness to noise.
Buffeting response of a composite cable-stayed bridge in a trumpet-shaped mountain pass
Authors: Shen Zheng-feng , Li Jia-wu , Gao Guang-zhong , Xue Xiao-feng
Published: September 2019

Previous research showed that wind characteristics were influenced by terrain. To accurately calculate the wind-induced bridge response, this article presented a comprehensive investigation of the wind characteristics of a trumpet-shaped mountain pass by long-term monitoring. Basic strong wind characteristics such as the wind rose, turbulence intensities, turbulence length scales, turbulence spectra and normalized cross-spectrum were discussed using 10 min intervals. Due to the different types of terrain on the two sides of the bridge site, this article attempted to reflect the influence of the terrain on the wind characteristics in different wind directions. The scatter plots of wind characteristics were presented directly on the terrain map. The effects of the turbulence characteristics, mean wind speed and aerodynamic admittance function on buffeting response of the composite cable-stayed bridge were discussed by the multimode coupled frequency domain. The results show that the wind profile is extremely twisted. The larger turbulent integral scale and the lower turbulence intensity appear in the direction along the river. The effect of the mean wind speed on the buffeting response is greater than that of the fluctuating wind characteristics. The aerodynamic admittance function proposed by Holmes has the largest reduction in buffeting response.
Application of adaptive sliding mode control (sigma adaption method) for an uncertain three-story benchmark structure
Authors: Katebi Javad , Jangara Jafar
Published: September 2019

This study develops the application of adaptive sliding mode control to earthquake-excited uncertain structures. Adaptive sliding mode control is useful as it only requires the boundness feature of uncertainties and disturbances to determine control gain (and not the amplitude of bounds). Moreover, the amplitude of chattering effect, the main drawback of sliding mode control, attenuates while stability and robustness are preserved. For this purpose, two adaptive-gain control algorithms are considered. In addition, a time-varying boundary layer is considered to increase the accuracy. In order to examine the feasibility of the applied method, a three-story benchmark structure is considered. Furthermore, performance indexes are used to evaluate the effectiveness of adaptive sliding mode control in comparison to sliding mode control and fuzzy sliding mode control. Comparison of the simulation results in accordance to performance indexes demonstrates that adaptive sliding mode control not only attenuates the amplitude of control effort (i.e. chattering amplitude) but also makes the control of the maximum response of the structure applying adaptive sliding mode control more convenient. It is shown that displacement and drift performance indexes of adaptive sliding mode control are equal to or less than ones of sliding mode control, while root mean square of the control effort of adaptive sliding mode control is attenuated around 50%.
Making pathways? A mixed methods analysis of young women who have left school early in ‘the new work order’
Authors: Ravn Signe , Churchill Brendan
Published: September 2019

Much research has investigated how young women with tertiary education fare in contemporary labour markets and pointed to persistent gender inequalities. However, very little is known about how young women who leave school early fare in the present climate. In this article we shed light on the challenges facing these women in the ‘new work order’. Drawing on quantitative and qualitative methods, we investigate how young Australian women who have left school before completing upper secondary education fare, and how they make choices regarding education and work as they envision their futures. Our analyses reveal a perceived and real tension between education and ‘real’ experience in the labour market. This leaves young women without upper secondary qualifications in a difficult position when making decisions about their futures.
Blaming consumers: Ideology and European austerity
Authors: Bradshaw Alan , Ostberg Jacob
Published: September 2019

This study analyzes a particular ideology of austerity as it spreads across Europe and reappears across diverse discourses. This ideology mobilizes the figure of the feckless consumer, who has overspent, who must come to regard their consumption as stupid, and therefore will accept austerity; not just as an inevitable outcome of bad decisions, but as holding the potential for moral redemption. We argue that ideology correlates this micro-frame of the feckless consumer with the macro condemnation of government expenditure and therefore is a hinge upon which the dissemination of austerity turns. The argument is developed by contrasting a Swedish television programme called Luxury Trap with the so-called ‘bail-out’ of the Irish state, as well as broader experiences of a pan-European discourse. Just as Luxury Trap’s hapless debtors are obliged to recognize their own stupidity through a process of brutal mortification, we argue that the Irish population has been mortified by an elite-driven narrative that measures consumption and expenditure as a gross average that reveals universal guilt and consumer excess. We see this powerful narrative implicating entire nations, obfuscating critical political economic analysis, and setting the ideological scene through which deep austerity programmes, ruinous to households and social infrastructures and starkly punitive to individuals, are pushed through. Critical to our argument is the over-determined status of the commodity itself whose invocation is central to the interpellation of a populace as excessive consumers. Instead of analysing social relations and neoliberalism’s contradictions, resentment and critique focusses upon material things, as though, for example, a plasma television was in itself a dangerous problem.
Mother, consumer, trader: Gendering the commodification of second-hand economies since the recession
Authors: Waight Emma
Published: September 2019

In Western contexts, ‘hand-me-down’ and sharing economies of children’s clothes, toys and equipment remain one of the most normalised cultures of second-hand consumption. This article explores the strategies used by mothers to realise the most economic value from these economies in current austere times with the increased possibilities offered by the democratisation of informal buying and selling spaces. Drawing on an ethnographic study of mothers participating in nearly new sales in the United Kingdom, the article outlines the myriad moralities influencing mothers’ everyday consumption, use and disposal of children’s goods. It argues that providing material goods for children is a thrifty skill with mothers thinking past point-of-purchase to the resale potential of second-hand items. This strategy of trading used children’s goods as a practice to circulate resources in the family and keep up with the commodification of childhood.
The aestheticization of restraint: The popular appeal of de-cluttering after the global financial crisis
Authors: Khamis Susie
Published: September 2019

The concept of consumer restraint has had a popular makeover. This is seen in the worldwide popularity of books, video tutorials and online discussion groups devoted to de-cluttering, and specifically the stunning success of professional organizer Marie Kondo and her best-selling book, The Life-Changing Magic of Tidying. De-cluttering sits on a broad continuum of alternative consumption that champions the benefits of consumer restraint, on multiple fronts: economic, environmental, psychological, and so on. Through Kondo, this is framed in positive, uplifting ways. This is distinct from the more critical, nuanced, or anti-consumerist rhetoric associated with more subversive advocates of alternative consumption, such as voluntary simplifiers or Occupy Wall Street. That said, just as the Occupy movement channeled growing frustration with how the reigning tenets of capitalist culture had shackled and misled the “99%,” de-cluttering finds cultural traction in the midst and wake of the Global Financial Crisis. Unlike Occupy though, Kondo’s appeal rests less on the logic and language of political economy than the more emotive vernacular of pop psychology. In this way, de-cluttering positions restraint as reflective of a highly developed and sophisticated sensibility, whereby individuals “own” their consumption choices and in turn craft carefully curated spaces. Therein lies the aestheticization of restraint: freed of any negative connotations (dour, miserly or miserable), the de-cluttered subject is autonomous, self-aware, and chic. Crucially, it also pivots on the slippery assumptions of the (new) neo liberal economy, which requires individuals to be agile, creative, and empowered.
Gleaning around the globe: Reframing urban thrift via practices and economies of hard rubbish reuse
Authors: Lewis Tania , Rauturier Frederic
Published: September 2019

This article examines the practice of gleaning or waste picking, that is, retrieving, reusing and exchanging disposed consumer goods collected from kerbsides and rubbish sites. While the literature has tended to be divided along geographic lines with waste picking either associated with poor communities in the Global South or understood as anti-consumerism activism in the North, this article reframes gleaning as a set of shared global practices conventionally positioned outside of market-based conceptions of economy, value and labour. Discussing a wide array of gleaning activities from around the world, the key argument made is that the alternative economies and practices associated with hard waste reuse activities can be seen as modelling different ways of living (with waste), consuming and disposing that offer potential environmental, economic and social benefits. The article argues that waste reuse activities should be viewed as a set of practices or routines that offer a critique of narrow neoliberal conceptions of economics, enacting instead broader models of value and labour that speak to notions of the public, social and (within limits) planetary good. Furthermore, these post-consumption practices challenge traditional conceptions of passive commodity consumption and disposal, extending the global value chain of goods to incorporate practices of sorting, disassemblage, repair and repurposing. In so doing, it suggests a need (particularly in the Global North) to reconfigure our relationship with and understanding of the life cycles of goods and materials in our lives and to re-materialise our everyday engagements with things as they shift from commodities to waste and back again.
A broader view on brands’ growth and decline
Authors: Formisano Marcello , Pauwels Koen , Zarantonello Lia
Published: September 2019

What does it take to grow a brand? How to avoid its decline? Some popular answers to these questions can be found in the research by Byron Sharp and others from the Ehrenberg-Bass (EB) Institute on “how brands grow.” In this article, we propose that such an approach, despite its strengths, lends itself to some limitations when taken too literally. We maintain that a broader notion and role of branding—encompassing brand equity, brand portfolio, and circular relationship of attitudes and behaviors—should be adopted by marketeers to derive better managerial implications for sustainable brand growth. We, therefore, invite marketers to not oversimplify Dirichlet evidences by thinking of availability as the only (costly) response to all marketing challenges.

The National Collegiate Athletic Association (NCAA) serves as the primary governing organization for college athletics. The NCAA is now responsible for representing a growing proportion of student-athletes who identify as Latinos. This study examined the experiences of Division I Latino male student-athletes. Questionnaires and interviews were used to understand how race and athletics shape their college experiences. Findings revealed the following three themes: racial remarks, peer stigmas, and cultural obligations.
How Diverging Interests in Public Health and Urban Planning Can Lead to Less Healthy Cities
Authors: Hensley Melissa , Mateo-Babiano Derlie , Minnery John , Pojani Dorina
Published: September 2019

Modern urban planning is intricately linked to public health concerns, with early twentieth-century planners segregating land uses and regulating development to help improve public health. Over time, this segregation created sprawling cities, now associated with poor health outcomes. This research explores how “ideas, interests, and institutions” (the 3Is) related to public health and planning have interacted in the planning of our cities. Using Brisbane, Australia, as a case study, we explore influences in public health and urban planning to better understand how their interaction influenced local government institutions and the development of Brisbane’s urban form.
Endovascular Bare Stenting for Isolated Superior Mesenteric Artery Dissection
Authors: Fu Yu-Fei , Cao Chi , Shi Yi-Bing , Song Tao
Published: September 2019

Purpose:

To investigate the clinical outcomes of endovascular bare stenting in patients with symptomatic isolated superior mesenteric artery (SMA) dissection (ISMAD).

Methods:

This study was a retrospective analysis which included a total of 9 patients with symptomatic ISMAD (7 males and 2 females, age range: 48-67 years) who were treated with endovascular bare stenting. Data regarding basic patient clinical characteristics, e-technical success of the operation, and long-term patient outcomes were assessed.

Results:

Endovascular bare stenting was found to be technically successful in all patients. A total of 9 stents were inserted in these 9 patients. Five patients presented with stable false lumen and 4 patients presented with shrinking of false lumen after stenting. Both the trunk and branches of the SMA remained patent in all patients after stent insertion. There was no incidence of procedure-related complications, with all patients experiencing progressive symptom relief and subsequent symptom abatement within 1 week of the operation. Over a median 24 month follow-up period (range: 12-36 months), abdominal computed tomographic angiography revealed that all patients had obliterated dissections. In addition, there were no instances of stent obstruction, intestinal necrosis, or antiplatelet related bleeding during the follow-up period.

Conclusions:

Endovascular bare stenting was found to be a safe and effective treatment for patients with ISMAD.

Published: September 2019

Objective. To test the hypothesis that an anti-inflammatory corticosteroid drug enhances spinal motor plasticity induced by acute intermittent hypoxia (AIH) in persons with chronic incomplete spinal cord injury (iSCI). Methods. Fourteen subjects with incomplete spinal cord injury (ASIA level C or D; mean age = 46 years) participated in a randomized, double-blinded, crossover, and placebo-controlled study. Subjects received either 60 mg oral prednisolone or a matching placebo, 1 hour before administration of AIH (15, 60-second hypoxic exposures; fraction of inspired oxygen [FiO2] = 0.09). Changes in voluntary ankle strength, lower extremity electromyograms (EMG), and serum inflammatory biomarkers were quantified. Results. Maximal ankle plantarflexion torque was significantly higher following prednisolone + AIH versus placebo + AIH (mean difference [MD] 9, 11, and 7 newton meter [N∙m] at 30, 60, and 120 minutes post-AIH, respectively; all Ps <.02). Soleus surface EMG during maximal voluntary contraction was also significantly increased following prednisolone + AIH (MD 3.5, P = .02 vs placebo + AIH), while activity of other leg muscles remained unchanged. Individuals had significantly higher levels of the anti-inflammatory serum biomarker interleukin-10 after prednisolone versus placebo ( P = .004 vs placebo + AIH). Conclusions. Pretreatment with prednisolone increased the capacity for AIH-induced functional motor plasticity, suggesting that suppression of inflammation enhances the efficacy of AIH administration in individuals with spinal cord injury.

Fault diagnosis method based on time domain weighted data aggregation and information fusion
Authors: Zhang Yu , Jiang Wen , Deng Xinyang
Published: September 2019

Fault diagnosis of equipment is a key issue in the industrial field, and it is essential to keep abreast of equipment status. However, previous studies either considered fault data at a single moment or gave the same weight to data over a period of time. In view of the problems above, fault diagnosis method based on time domain weighted data aggregation and information fusion is proposed in this article. First, the monitored data of sensors loaded by the equipment are aggregated utilizing the linear decaying weights. Then, Gaussian models of each fault type under different fault features are established based on aggregated data. And the basic probability assignments are generated by matching aggregated testing samples with the constructed Gaussian model. At last, the basic probability assignments generated under each fault feature are fused by Dempster combination rule. The proposed method is verified and the results show that the total fault recognition rate can reach 97.5%, which increased by 1.9% compared with the method that Gaussian model constructed by original data.
Epistemic Strategies in Ethical Review: REB Members’ Experiences of Assessing Probable Impacts of Research for Human Subjects
Authors: Cox Susan M. , McDonald Michael , Townsend Anne
Published: September 2019

Research ethics boards (REBs) are charged with applying ethical standards to protect the rights and interests of research subjects. Little, however, is known about how REB members perceive probable impacts of research participation for subjects. Drawing on in-depth interviews with 40 Canadian REB members, we identify three frequently reported epistemic strategies, including reliance on a local REB culture or ethos, use of resident authorities, and protective imagination. Far less commonly described strategies included direct or indirect contact with research subjects. REB members also reflected upon significant gaps in their knowledge and thus the importance of knowing what we don’t know. Recommendations arising from this support an evidence-based practice for ethics review involving clear epistemic standards for REBs learning about subjects’ experiences.
Concomitant Transapical Transcatheter Aortic Valve Implantation and Transapical Mitral Valve Repair With NeoChord Implantation
Authors: Stelzmueller Marie-Elisabeth , Zilberszac Robert , Heinrich Nikolaus , Mora Bruno , Laufer Guenther , Wisser Wilfried
Published: September 2019

One-third of the patients with severe symptomatic aortic valve stenosis (sAS) present with hemodynamic relevant mitral valve insufficiency (rMI). In patients who undergo conventional surgery, the rMI never would be left untreated; however, in cases of transcatheter aortic valve implantation (TAVI), the impact of rMI is often overlooked and left untreated. The combination of transapical TAVI (TA-TAVI) and NeoChord implantation represents a novel, promising therapeutic option for high-risk-surgery patients with sAS and rMI due to a prolapsed or flailed leaflet. This case report describes 2 patients (1 male, 1 female; mean age 82 years) who underwent TA-TAVI and concomitant NeoChord implantation at our institute. Both presented with sAS and rMI due to a prolapse of the P2 segment of the mitral valve. At first, the TA-TAVI was implanted under angio-guidance, followed by three-dimensional echo-guided implantation of the NeoChords, through the same approach, which was slightly posterior and lateral to the apex. TA-TAVI using an Edwards Sapien 3 (26 mm, n = 1 and 29 mm, n = 1) and NeoChord implantation (2 in the first and 3 in the second patient) was successful in both cases. Post-intervention discharge echo indicated no paravalvular or central insufficiency after the procedure and only a trace of mitral valve insufficiency. TA-TAVI and concomitant NeoChord implantation is a feasible and promising treatment option for high-risk patients with rMI. Despite its technical demands, in experienced hands, it is a safe procedure for those not well suited for surgical intervention.

Published: September 2019

Practical guidance for navigating issues associated with combining mixed methods and case study research approaches is in short supply, particularly for novice researchers who may grapple with numerous decision points in planning and conducting such studies. This methodological discussion examines the decision-making process used in a qualitatively driven mixed methods dissertation study with a focus on how mixed methods and case study research approaches can be applied together to enhance case descriptions and interpretations. This discussion contributes to the field of mixed methods research methodology by expanding conversations about the inherent messiness of mixed methods research and by providing practical guidance to researchers interested in applying a mixed methods case study approach.

This article will be of interest both for researchers who are doing or planning to conduct research in Kazakhstan and Central Asia and those who are researching in nondemocratic contexts as methodological challenges of an authoritarian regime stretch beyond the geographical boundaries.
The effect of head movement on the bounding gait of a quadruped robot with an active spine
Authors: Chen Dongliang , Gong Chen , Xing Fuze , Zhou Changhe , Qi Mengfei , Wang Lianfu
Published: September 2019

It is a common phenomenon in the movement of the quadruped mammals accompanied with head swings. Inspired by this, this article attempts to add head motion to the bounding gait of a quadruped robot. According to the theoretical analysis, there are two main functions of the head. First, the head can realize the active control of the center of mass position of the robot, which is of great significance to the stable motion of the robot. Second, the swing of the head plays a role in regulating the pitch angle of the torso and improves the coordination and stability of the motion. A simplified quadruped robot model with a head and spine joint is established and analyzed theoretically. The regularity of head movement in periodic bounding gait is summarized. Through simulation and experiment, we confirm the two roles of the head in the bounding gait of a quadruped robot.
Adaptive coordinated motion control with variable forgetting factor for a dual-arm space robot in post-capture of a noncooperative target
Authors: Jiao Chunting , Yang Jun , Wang Xueqian , Liang Bin
Published: September 2019

To overcome the problem of dynamics coupling between a space robot and a target satellite, this study introduces a new coordinated motion control approach with an adaptive filtering algorithm for a dual-arm free-floating space robot. Based on the reaction null space control scheme, one arm is used to complete the capture task and the other to counteract disturbance to the space base. However, when space robot captures a noncooperative target, the system may experience abrupt changes in dynamic parameters and output measurement noise, which can cause traditional control methods to achieve poor results in practical applications. Thus, an adaptive filtering algorithm with a variable forgetting factor is proposed to improve the tracking capabilities and robustness of the system. The convergence analysis is performed based on a Lyapunov function. The simulation results demonstrate the effectiveness of the proposed algorithm.
Surgical fires: Still a burning issue in England and Wales

The National Reporting and Learning System database identified 37 reports of surgical fires in England and Wales between January 2012 and December 2018 – over 52% resulting in some degree of harm. Surgical fires remain preventable adverse events that can be avoided by adherence to effective preventative strategies and improved education. This article surveys the existing literature, addressing the fire triad and how to effectively manage and prevent a surgical fire.
Improving the day case rate for laparoscopic cholecystectomy via introduction of a dedicated clinical pathway
Authors: Aslet MED , Yates DRA , Wasawo S
Published: September 2019

Day case laparoscopic cholecystectomy is a safe and economical procedure. However, successful discharge on the same day of the procedure has been difficult to achieve at our institution. This study introduced a standardised anaesthetic pathway aiming to increase same day discharges. This led to an overall increase in same day discharges from 42.0% to 54.1%. When the pathway was fully followed, 71% of patients were discharged on the same day. When the pathway was not followed at all, the same day discharge rate was 0%. Our study successfully demonstrates that small enhancements to perioperative care can accelerate patient recovery and improve same day discharges.

Published: September 2019

The aim of this retrospective study was to evaluate the effect of implementing the combination of thoracic epidural analgesia and multimodal analgesia by a dedicated acute pain service on opioid consumption and postoperative outcomes in patients undergoing pancreaticoduodenectomy. Opioid consumption during postoperative days 0–3 was compared in the acute pain service versus non-acute pain service cohort. Between matched cohorts, the median (quartiles) total opioid consumption during postoperative days 0–3 was 114mg morphine equivalents (54.7, 212.4mg morphine equivalents) in the non-acute pain service cohort and 47.4mg morphine equivalents (38.1, 100.8mg morphine equivalents) in the acute pain service cohort; the median difference was 44.8mg morphine equivalents (95% CI 14.2–90.2mg morphine equivalents, p = 0.002). The median difference in hospital length of stay was 2.0 days (95% confidence interval 0.8–4.0, p = 0.01), favouring the acute pain service cohort. A dedicated acute pain service implementing thoracic epidural analgesia in conjunction with multimodal analgesia was associated with decreased opioid consumption and hospital length of stay.
Impact of the gut microbiota on immune checkpoint inhibitor-associated toxicities
Authors: Pezo Rossanna C. , Wong Matthew , Martin Alberto
Published: September 2019

Immune checkpoint inhibitors (ICIs) have transformed the treatment of patients with advanced cancers. However, the majority of patients do not respond or develop early progressive disease. A substantial number also develop immune-mediated toxicities that may lead to early treatment discontinuation. Gastrointestinal toxicities in the form of diarrhea and colitis are common and may resemble that observed in patients with inflammatory bowel disease (IBD). Alterations in the gut microbiota are thought to play an important role in mediating the intestinal inflammation that is associated with immune-mediated colitis. In this review, the authors’ objective is to provide an overview of the gastrointestinal and hepatic toxicities that can be seen with ICIs and discuss the interactions between gut microbiota and the immune response. The authors also highlight the potential role for fecal microbial transfer (FMT) as an approach to improve therapeutic efficacy and decrease toxicity.

Authors: Pejić Bach Mirjana , Bosilj Vukšić Vesna , Suša Vugec Dalia , Stjepić Ana-Marija
Published: September 2019

Business intelligence (BI) and business process management (BPM) are widely implemented in various organizations. However, their impact on organizational performance strongly depends on their alignment. Previous research has focused mainly on large companies. Small and medium-sized enterprises (SMEs) also started to use BI and BPM in order to improve their performance. However, the research regarding this issue is scarce. The goal of the article is to examine the interrelationship of BI and BPM and their impact on organizational performance of SMEs. In order to attain this goal, a systematic literature review and a survey research on the sample of SMEs in Croatia and Slovenia have been conducted.
Comparison of heat transfer performance of ZnO-PG, α-Al2O3-PG, and γ-Al2O3-PG nanofluids in car radiator
Authors: Zhou XiaoRong , Wang Yi , Zheng Kai , Huang Haozhong
Published: September 2019

In this study, the cooling performance of nanofluids in car radiators was investigated. A car radiator, temperature measuring instrument, and other components were used to set up the experimental device, and the temperature of nanofluids passing through the radiator was measured by this device. Three kinds of nanoparticles, γ-Al2O3, α-Al2O3, and ZnO, were added to propylene glycol to prepared nanofluids, and the effects of nanoparticle size and type, volume concentration, initial temperature, and flow rate were tested. The results indicated that the heat transfer coefficients of all nanofluids first increased and then decreased with an increase in volume concentration. The ZnO-propylene glycol nanofluid reached a maximum heat transfer coefficient at 0.3 vol%, and the coefficient decreased by 25.6% with an increase in volume concentration from 0.3 vol% to 0.5 vol%. Smaller particles provided a better cooling performance, and the 0.1 vol% γ-Al2O3-propylene glycol nanofluid had a 19.9% increase in heat transfer coefficient compared with that of α-Al2O3-propylene glycol. An increase in flow rate resulted in a 10.5% increase in the heat transfer coefficient of the 0.5 vol% α-Al2O3-propylene glycol nanofluid. In addition, the experimental temperature range of 40–60°C improved the heat transfer coefficient of the 0.2 vol% ZnO-propylene glycol nanofluid by 46.4%.

Published: September 2019

Paeoniflorin (PF) is an important pharmacological component of some Chinese traditional herbal formulas, such as Bai Shao, Chi Shao, and Dan Pi, which have been clinically used for centuries. Although many experimental studies have explored a wide range of pharmacological properties of PF, including anticancer, anti-inflammatory, antioxidant, immunoregulatory, and prevention of insulin resistance, there is no review to describe these reported effects systematically, especially the antitumor effect and the underlying mechanisms. In this review, we summarize the recent progress on the anticancer profiles both in vitro and in vivo of PF. Moreover, we highlight the integrated molecular mechanisms of PF and contemplate its future prospects as a potential anticancer drug.
High-Status Exemplars and the Misperception of the Asian-White Wealth Gap
Authors: Kuo Entung Enya , Kraus Michael W. , Richeson Jennifer A.
Published: September 2019

In this research, we test the central hypothesis that perceptions of Asian Americans as a high-status “model minority” lead to overestimates of the extent of wealth equality between Asian and White Americans. We test this hypothesis across three studies that manipulate the salience of high- or low-status Asian American exemplars before soliciting estimates of Asian-White wealth equality. A meta-analysis of the results revealed that participants significantly overestimated Asian-White wealth equality and that making low- versus high-status Asian American exemplars salient decreased this tendency. These data suggest that activation of high-status Asian American exemplars elicits greater overestimates of Asian-White wealth equality, obscuring existing wealth disparities relative to White Americans and significantly downplaying the economic inequality that burdens a subset of Asian Americans from less prototypical ethnic backgrounds. The findings echo recent calls by sociologists and political scientists for a more nuanced understanding of the diversity and economic inequality among Asian American communities.
Resolving the Human–Object Divide in Sexual Objectification: How We Settle the Categorization Conflict When Categorizing Objectified and Nonobjectified Human Targets
Authors: Vaes Jeroen , Cogoni Carlotta , Calcagnì Antonio
Published: September 2019

Using a mouse-tracking technique, we measured the strength and the temporal unfolding of the conflict when people categorize objectified and nonobjectified human stimuli in the human or object category. We recorded participants’ hand movements when they categorized male and female, objectified and nonobjectified, human, and doll-like stimuli in the person and object categories. As expected, objectified women created a stronger categorization conflict compared to all other human stimuli. The nature of the mouse trajectories indicated that this response competition was caused by the distractor (object category) rather than the target (person category) and showed to be smooth rather than abrupt suggesting dynamic competition between the object–human categories rather than the sequential unfolding of a dual process. These findings demonstrate that the human–object divide fades when women (but not men) are objectified. The implications of the current findings for theorizing on processes of sexual objectification are discussed.

Following the tsunamis occurred in Japan (2011) and Indian Ocean (2004), investigating interaction between coastal structures and tsunamis became necessary. Although several attempts have been made to estimate the tsunami forces acting on the coastal structures, there still remain inconsistencies among the published design guidelines. This research includes an experimental study to investigate the interaction between a tsunami surge and a coastal structure. The tsunami surge was generated using a novel dam-break system, capable of generating higher tsunami surges than the previous simulations. The relations between surge velocity, surge depth, and surge-induced pressure on the structure were presented. In the surge-induced pressure–time histories, there were three identified force components, namely, run-up, impulsive and quasi-steady hydrodynamics. Furthermore, this research presents a comparison made between the experimental results and existing tsunami guidelines. The ratio of impulsive force to hydrodynamic force was found around 2.4 for each tsunami surge. The hydrodynamic forces were found to be higher with respect to those determined using the ‘Federal Emergency Management Agency’ FEMA P646 guidelines, whereas they were approximately in agreement with those obtained by FEMA 55. Moreover, the results showed that the ‘Structural Design Method of Building for Tsunami Resistance’ overestimates the impulsive force.
Process, mechanism and the project of economic geography

This response engages Yeung’s arguments about the value of critical realism (CR) in economic geography (EG), and how they can be further strengthened by better theorizing mechanism and process in relation to mid-level concepts like neoliberalization and path dependence. While there is much to value in the attention Yeung pays to how economic geographers conceptualize and study relational socio-spatial change, I argue that the lack of attention to how mid-level concepts relate to macro-level structures hampers the goal of more robust theorizing. Moreover, the association of CR with the reassertion of a disciplinary ‘core’ suggests a normative project that ignores or marginalizes diverse critical approaches in EG, which are framed as a sign of weaknesses rather than disciplinary strength.

This report summarizes the published cases of sideroblastic anemia with B cell immunodeficiency, periodic fevers, and developmental delay and highlights associated mucocutaneous features.
Cutaneous sarcoidosis in a melanoma scar: A case report
Authors: Fournier Cynthia , Vallée Sheila , Perron Émilie , Thérien Geneviève
Published: September 2019

Sarcoidosis is an inflammatory multisystemic disease of unknown etiology with multiple presentations of cutaneous lesions. It characteristically infiltrates scars due to several kind of trauma such as surgery, tattoo and even herpes zoster. We present a case of a 65-year-old woman with progressive distal paresthesia and motor weakness. She was referred to our dermatology clinic for a new violaceous nodular plaque within an old melanoma scar on the posterior neck. On positron emission tomography–computed tomography, there were multiple enlarged thoracic lymphadenopathy and a fluorodeoxyglucose-avid cutaneous lesion on the posterior neck, right in the melanoma scar. Cutaneous and nerve biopsies showed non-necrotising granulomas, supporting the diagnosis of systemic sarcoidosis and excluding melanoma recurrence with metastasis. It is the first case of cutaneous sarcoidosis arising within a melanoma scar. Interestingly, patients with melanoma have a higher risk of sarcoidosis.

Background

Inverted papillomas (IPs) are benign, locally aggressive neoplasms with a high recurrence rate that most commonly arise from the lateral nasal wall. Rarely, IP can originate from the lacrimal sac and/or nasolacrimal duct (NLD) system. A 58-year-old man presented with chronic epiphora and an enlarging mass inferior to his left medial canthal tendon (MCT) for 2 years.

Objective

The patients’ clinical presentation and surgical management are described. A literature review on IP of the lacrimal sac and NLD system was conducted.

Methods

Case report.

Results

We present a case of an IP that arose primarily from the lacrimal sac and grew below the MCT rather than extending above it. This is one of few published case reports detailing the use of a combined endoscopic and external approach for the resection of an IP of the lacrimal sac.

Conclusion

Combined endoscopic and external resection is a viable approach for complete removal of extensive IP of the lacrimal sac and NLD system. IP arising from the lacrimal sac may grow below the MCT or extend above it as previously reported.

Dermatofibrosarcoma protuberans (DFSP) is a rare sarcoma of soft tissue representing about 1% of all tumors. In addition, DFSP occurs commonly on the trunk and extremities, and only a few cases of DFSP have been observed on the breast. In men, only 11 cases, including this case, have been reported. In this article, we present a case of left breast DFSP that occurred in a 44-year-old man. The physical examination revealed a left breast tender mass, which invaded the skin. The tumor was staged as T4b N0 M0. Mammography and sonography showed a suspect mass of the left breast. The biopsy and immunochemistry permitted the diagnosis of DFSP of the left breast. The patient had a left mammectomy, with free margins. He presents no evident sign of recurrence 7 months later.
