Understanding Assimilation-contrast Effects in Online Rating Systems
Authors: Zhang Xiaoying , Xie Hong , Zhao Junzhou , Lui John C. S.
Published: October 2019

“Unbiasedness,” which is an important property to ensure that users’ ratings indeed reflect their true evaluations of products, is vital both in shaping consumer purchase decisions and providing reliable recommendations in online rating systems. Recent experimental studies showed that distortions from historical ratings would ruin the unbiasedness of subsequent ratings. How to “discover” historical distortions in each single rating (or at the micro-level), and perform the “debiasing operations” are our main objective. Using 42M real customer ratings, we first show that users either “assimilate” or “contrast” to historical ratings under different scenarios, which can be further explained by a well-known psychological argument: the “Assimilate-Contrast” theory. This motivates us to propose the Historical Influence Aware Latent Factor Model (HIALF), the “first” model for real rating systems to capture and mitigate historical distortions in each single rating. HIALF allows us to study the influence patterns of historical ratings from a modelling perspective, which perfectly matches the assimilation and contrast effects observed in experiments. Moreover, HIALF achieves significant improvements in predicting subsequent ratings and characterizing relationships in ratings. It also contributes to better recommendations, wiser consumer purchase decisions, and deeper understanding of historical distortions in both honest rating and misbehaving rating settings.
Maternal microbiome and the hypertensive disorder of pregnancy, preeclampsia
Authors: Beckers Kalie F. , Sones Jenny L.
Published: October 2019

Preeclampsia (PE) is a pregnancy-specific disorder that can be life threatening for both mother and baby. It is characterized by a new onset hypertension during the second half of pregnancy and affects ~300,000 women in the United States every year. There is no cure for PE, and the only effective treatment is delivery of the placenta and the fetus, which is often preterm. PE is believed to be a severe manifestation of placental dysfunction due to early angiogenic imbalances and inflammatory disturbances; however, the cause of this is unknown. The once thought “sterile” placenta now has been proposed to have a unique microbiome of its own. Under ideal conditions, the microbiome represents a balanced bacterial community that is important to the maintenance of a healthy environment. Dysbiosis of these communities may lead to inflammation that potentially contributes to adverse pregnancy outcomes, such as preterm birth and PE. Thus far, the female reproductive tract microbiome has been found to be influenced by periodontal disease, cardiometabolic complications, and maternal obesity, all of which have been identified as contributors to PE. This review will look at the maternal reproductive tract microbiome, evidence for and against, and its role in pregnancy and PE-related events as well as data from relevant mouse models that could be useful for further investigating the influence of the reproductive tract microbiome on the pathogenesis of PE.

Published: October 2019

Cisplatin resistance is a major barrier in the effective treatment of lung cancer. Cisplatin-resistant (CR) lung cancer cells do not primarily use glucose but rather consume amino acids such as glutamine and tryptophan (Trp) for survival. CR cells activate the kynurenine (KYN) pathway (KP) to cope with excessive reactive oxygen species (ROS) and maintain homeostasis for growth and proliferation. Consequently, indoleamine 2,3-dioxygenase-1 (IDO1) becomes an essential enzyme for CR cells' survival because it initiates and regulates the first step in the KP. Increased IDO1 activities and ROS levels are found in CR cells versus cisplatin-sensitive lung cancer. Importantly, significantly greater KYN/Trp ratio (P = 0.005) is detected in serum of patients who fail cisplatin when compared with naïve treatment. Knocking down IDO1 using shRNA or IDO1 inhibitors heightens ROS levels and results in a significant growth inhibitory effect only on CR cells and not on cisplatin-sensitive cells. Exposing CR cells to antioxidant (TIRON) results in suppression of IDO1 activity and confers resistance to IDO1 inhibition, indicating an interrelationship between ROS and IDO1. Because KYN plays a critical role in reprogramming naïve T cells to the immune-suppressive regulatory T-cell (T-reg) phenotype, we observed higher expression of TGFβ, FoxP3, and CD4+CD25+ in mice bearing CR tumors compared with tumors from cisplatin-sensitive counterparts.

Implications:

Findings suggest that the enzyme-inhibitory activity and antitumor efficacy of IDO1 inhibitors rely in part on ROS levels, arguing that IDO1 expression alone may be insufficient to determine the clinical benefits for this class of experimental cancer drugs. Importantly, IDO1 inhibitors may be more suitable to treat patients with lung cancer who failed cisplatin therapy than naïve treatment patients.

Published: October 2019

Background: Adalimumab is the only approved compound for the treatment of adult patients with moderate-to-severe hidradenitis suppurativa (HS) who did not respond to a systemic classical treatment. Despite its significant short- and long-term efficacy, a percentage of patients do not respond sufficiently. Moreover, some primary responders experience a response loss with time. Objective: To analyse the effectiveness of adalimumab dose intensification in HS patients. Methods: A case series of adalimumab 80 mg/week subcutaneously (s.c.) compassionate use in patients with HS, who did not respond sufficiently or in primary responders with progressive response loss to the registered adalimumab dose of 40 mg/week s.c. Patients were collected and evaluated retrospectively. Patients’ data were extracted from medical records. Results: The 14 patients collected were Caucasian with HS of Hurley stage II–III and moderate or severe International HS Severity Score System (IHS4) stage. Adalimumab dose intensification significantly improved IHS4 score, Pain Index, HS-Physician Global Assessment, pain, and Cardiff Dermatology Life Quality Index. Two young female patients with HS and Crohn’s disease developed psoriatic lesions during the treatment with adalimumab 80 mg/week s.c. Conclusion: An enhanced level of effectiveness was assessed in the majority of the HS patients treated with adalimumab dose intensification (80 mg/week s.c.). Larger studies are required to evaluate this observation.

Published: October 2019

Nitroglycerin (NTG), a nitric oxide-donating drug, may increase tumor blood flow and consequently increase cancer drug delivery to tumor cells. Thymidylate synthase (TS) is an essential enzyme for the de novo synthesis of deoxythymidine monophosphate; we had found that knocking down the expression of TS sensitizes lung cancer cells to cisplatin-induced cytotoxicity. However, whether NTG and cisplatin could induce synergistic cytotoxicity in nonsmall cell lung cancer (NSCLC) cells through modulating TS expression is unknown. In this study, NTG decreased TS expression in an AKT, also known as Protein kinase B (PKB) inactivation dependent manner in human lung adenocarcinoma A549 and squamous cell carcinoma H1703 cells. Enhancement of AKT activity by transfection with constitutive active AKT vectors increased the TS expression level as well as the cell survival pretreated by NTG. Moreover, NTG synergistically enhanced cytotoxicity and cell growth inhibition by cisplatin treatment in NSCLC cells, which were associated with downregulation of TS expression and inactivation of AKT in A549 and H1703 cells. Together, these results may provide a rationale to combine NTG with cisplatin-based chemotherapy to enhance the therapeutic effect for lung cancer in the future.

Published: October 2019

Depression and anxiety are common psychiatric disorders accounting for social and economic burdens. Previous studies have shown that oxidative stress and oxidant/antioxidant imbalance are involved in the pathophysiology of psychiatric disorders. Experiencing early-life adversities (like maternal separation [MS] stress) provoked psychiatric disorders. Trigonelline (TRG) is a pyridine alkaloid that has various pharmacological effects including hypoglycemic, neuroprotective and memory-improving properties. To investigate the antidepressant- and anxiolytic-like effects of TRG focusing oxidative stress, we applied the MS paradigm to male mice at postnatal day (PND) 2–14 (3 h daily, 9–12 a.m.) and investigated the behaviors at PND 45–47. Using valid behavioral tests including a forced swimming test (FST), splash test, open field test (OFT) and elevated plus maze (EPM), we investigated behavioral modifications. Additionally, we examined the effects of MS and TRG treatment on the level of malondialdehyde (MDA), nitric oxide (NO) and also antioxidant capacity in the brain and serum. Our results showed that MS provoked depressive- and anxiety-like behaviors in the FST, OFT, EPM and splash test, which are associated with an increase in MDA and NO levels as well as a decrease in antioxidant capacity in the brain and serum samples. Findings determined that TRG significantly reversed the negative effects of MS on behavior that is accompanied by a decrease in MDA and NO as well as an increase in antioxidant capacity. Findings of the present study showed that beneficial effects of TRG may be, at least partially, mediated via the reduction of oxidative stress and an increase of antioxidant capacity.
Leaving Afghanistan: Enduring Lessons from the Soviet Politburo
Authors: Drozdova Katya , Felter Joseph H.
Published: October 2019

A systematic analysis of formerly classified Soviet Politburo documents challenges popular misconceptions about the Soviet withdrawal from Afghanistan. The archival evidence indicates that, far from being a near-complete and chaotic failure, the withdrawal was based on a coherent exit strategy that initially achieved its limited objectives. Moscow's strategy enabled Soviet-trained Afghan forces to withstand the insurgent offensive and allowed the Afghan government to remain in power nearly three years after the Soviet combat forces departed. The Soviet-installed Afghan government ultimately collapsed not from military defeat or bankruptcy but from internal political strife and betrayals. Even though Soviet leaders failed to secure long-term gains as their strategy ran out of time, their experience provides relevant lessons for U.S. strategy formulation in Afghanistan following the withdrawal of U.S. combat forces and is an instructive case that can inform theories of great-power retraction from foreign intervention in general.
At Home among Strangers: U.S. Artists, the Soviet Union, and the Myth of Rockwell Kent during the Cold War
Authors: Chunikhin Kirill
Published: October 2019

After World War II, Soviet institutions organized many exhibitions of the American artist Rockwell Kent that bypassed the U.S. government. Promotion of Kent's work in the USSR was an exclusively Soviet enterprise. This article sheds new light on the Soviet approach to the representation of U.S. visual art during the Cold War. Drawing on U.S. and Russian archives, the article provides a comprehensive analysis of the political and aesthetic factors that resulted in Kent's immense popularity in the Soviet Union. Contextualizing the Soviet representation of Kent within relevant Cold War contexts, the article shows that his art occupied a specific symbolic position in Soviet culture. Soviet propaganda reconceptualized his biography and established the “Myth of Rockwell Kent”—a myth that helped to legitimate Soviet ideology and anti-American propaganda.
The United States and Neutral Countries in Europe, 1945–1991
Authors: Nilsson Mikael
Published: October 2019

The post-Cold War era has led to a proliferation of scholarship on U.S. policy toward four neutral European countries—Austria, Finland, Switzerland, and Sweden—during the Cold War. This article provides a survey of the latest literature on U.S. policy toward these four countries as well as general comments about the U.S. government's approach to European neutrality from 1945 to 1991.
Effects of Motivation Framing and Content Domain on Intentions to Eat Plant- and Animal-Based Foods
Authors: Duchene T. N. , Jackson L. M.
Published: October 2019

This study examined the effectiveness of persuasive messages intended to encourage people to eat more plant foods and fewer nonhuman animal foods. One hundred twelve participants reported their eating habits and read an article that emphasized health or ethical implications of food choices as well as a brochure that used autonomy promoting or controlling motivational framing to encourage eating plant foods. They then indicated their future eating intentions. Across conditions, participants reported the intention to eat more plant foods following the manipulations compared to their current eating habits. In addition, people who perceived the article as promoting greater choice in eating habits reported an intention to decrease their consumption of meat and increase their consumption of higher protein plant foods. These findings can assist animal rights or welfare advocates, health-care practitioners, and educators in encouraging people to eat more plant foods and fewer animal foods.
Body size and life history traits of the fire salamander Salamandra salamandra from Poland
Authors: Najbar Anna , Konowalik Agnieszka , Halupka Konrad , Najbar Bartłomiej , Ogielska Maria
Published: October 2019

The fire salamander Salamandra salamandra is a widespread taxon in Europe, exhibiting great intraspecific diversity in phenotype and life history traits across its geographical distribution. Here, we studied body size, sexual dimorphism, age, growth rate and condition of fire salamanders from the north-eastern margin of its range. In total, 2,102 individuals from 23 populations representing the Polish parts of the Sudetes and the Carpathian Mountains were sampled between 2004 and 2016. Body traits and age showed significant differences between the western (the Sudetes) and eastern (the Carpathians) groups of populations. Salamanders from the Carpathians tended to be longer, heavier and older. Female-biased sexual size dimorphism was found only in the Carpathians. Body condition at the beginning of the season was poor, then increased to reach a peak in early June, and deteriorated toward the end of the season. Age estimated by skeletochronology on phalangeal bones ranged from 2 to 16 years in both females and males, with the highest share of 7- to 9-year-old individuals. Age of juveniles ranged from 1 to 5 years in the Sudetes and from 1 to 4 years in the Carpathians. Growth curves (fitted using von Bertalanffy’s model) were asymptotic throughout the individual lifespans, but exhibited differences between sexes and mountain ranges. Altitude did not explain differences in characteristics of populations living in the two mountain ranges, but these differences most probably resulted from habitat quality (better in the Carpathians) and adverse human impact (higher in the Sudetes).
Board Diversity in Terms of Gender: a Recommendation for Mauritius
Authors: Beebeejaun Ambareen
Published: October 2019

The increased presence of women on the boards of corporations is an international trend worth following by all countries. There are many good reasons for increasing gender diversity on boards have been evidenced by various studies such as better decisions, performance, and representation of the consumer base. However, the country of Mauritius has been lagging behind in terms of legislative initiatives to promote female representation on corporate boards. A study conducted by the Hay Group in association with the Mauritius Institute of Directors in 2015 supports this fact.

The study seeks to identify the relative benefits behind the global trend of achieving gender diversity on corporate boards and on the factors that impact the representation of women on such boards. Some various kinds of regimes and initiatives that have been developed in some countries mainly Norway and the UK will be analysed to deal with the issue of underrepresentation of women on corporate boards. The purpose behind this research is to provide effective recommendations for Mauritius to achieve a greater level of gender diversity on corporate boards.

The methodologies for the research are, in essence, comprised of the black letter approach which analyses the legal provisions relating to directors in Mauritius, Norway, and the UK. Journals, books, and reports amongst others will be also examined.

The paper aims at responding to the research objectives set out above. In particular, a soft-law approach in terms of voluntary target and non-financial disclosure in terms of gender diversity status is suggested as a first step to resolve low representation of women on corporate boards in Mauritius.
Postoperative Opioid Use and Pain Management Following Otologic and Neurotologic Surgery
Authors: Boyd Christopher , Shew Matthew , Penn Joseph , Muelleman Thomas , Lin James , Staecker Hinrich , Wichova Helena
Published: October 2019

Objectives:

The topic of prescription opioid overuse remains a growing concern in the United States. Our objective is to provide insight into pain perception and opioid use based on a patient cohort undergoing common otologic and neurotologic surgeries.

Study Design:

Prospective observational study with patient questionnaire.

Setting:

Single academic medical center.

Subjects and Methods:

Adult patients undergoing otologic and neurotologic procedures by two fellowship trained neurotologists between June and November of 2018 were included in this study. During first postoperative follow-up, participants completed a questionnaire assessing perceived postoperative pain and its impact on quality of life, pain management techniques, and extent of prescription opioid use.

Results:

A total of 47 patients met inclusion and exclusion criteria. The median pain score was 3 out of 10 (Interquartile Range [IQR] = 2-6) with no significant gender differences ( P = .92). Patients were prescribed a median of 15.0 (IQR = 10.0-15.0) tablets of opioid pain medication postoperatively, but only used a median of 4.0 (IQR = 1.0-11.5) tablets at the time of first follow-up. Measured quality of life areas included sleep, physical activity, work, and mood. Sleep was most commonly affected, with 69.4% of patients noting disturbances.

Conclusions:

This study suggests that practitioners may over-estimate the need for opioid pain medication following otologic and neurotologic surgery. It also demonstrates the need for ongoing patient education regarding opioid risks, alternatives, and measures to prevent diversion.
‘My Mother, My God,’ ‘Why have you forsaken me?’: An Exegetical Note on Psalm 22 as Christian Scripture
Authors: Parker Jonathan D.
Published: October 2019

This essay argues for a re-reading of the lament in Psalm 22:1–5, 9–11 as Christian Scripture. This reading of the Old Testament as Christian Scripture redresses an imbalance in Christian theology, which tends to highlight difficulties in Jesus’ cry of dereliction but obscures its lament. This lament is central to the cross as solidarity with the experience of human suffering as betrayal by God and as an invitation for humanity to cry out for God’s response, found ultimately in the cross. In particular, the essay offers a new, feminist, birth-sensitive interpretation of Psalm 22:9–11 and a new, feminist translation of Psalm 22:10b, accenting God’s motherhood in the passage.
Ethics, politics and embodied imagination in crafting scientific knowledge
Authors: Bell Emma , Willmott Hugh
Published: October 2019

This article explores ‘research-as-craft’ as a sensitizing concept for disclosing the presence of ethics and politics, as well as embodiment and imagination, in the doing and representation of scientific activity. Routinely unnoticed, marginalized or suppressed in methodology sections of articles and methodology textbooks, research-as-craft gestures towards messy, tacit, uncertain, yet rarely thematized, practices that are central to getting science done. To acknowledge and address the significance of research-as-craft in knowledge production, we show how it relates to three forms of reflexivity – constitutive, epistemic and disruptive. Through this we demonstrate the craftiness that is required when struggling with the indeterminacy that is endemic to the production and communication of scientific knowledge. By showing how empirical situations require imaginative interpretation by embodied researchers, we argue that our conception of research-as-craft facilitates appreciation of scientific inquiry as an indexical activity that involves the crafted object and the researcher in an ethico-political process of co-constituting knowledge.
Preparation of open cell rigid polyurethane foams and modified with organo-kaolin
Authors: Wang Guojian , Yang Tao
Published: October 2019

The open cell rigid polyurethane foam (ORPUF) was prepared by adding chemical cell openers including O-500 and AK-9903. The FTIR results of cell openers and open cell rate of ORPUFs showed that O-500 has more effective cell opening capacity. In the ORPUF foaming formulation using O-500 as cell opener, silane coupling agent (KH-550) modified kaolin (organo-kaolin) was introduced into ORPUF with different weight loadings. The cellular morphology, apparent density, and compressive strength of the foams were tested in order to investigate the effects of organo-kaolin on the open cell rate and compressive property of the foams. The results showed that the open cell rate of ORPUFs slightly increased from 83.9% to 92.9% with the content of organo-kaolin. Meanwhile, compared to neat ORPUF, the compressive strength of foams increased by 72.8% when the content of introduced organo-kaolin was 4 parts per hundred of polyol by mass (php).
Influence of machining damage generated during trimming of CFRP composite on the compressive strength
Authors: Nguyen-Dinh N , Bouvet C , Zitoune R
Published: October 2019

Machining of composite materials is a challenging task due to the heterogeneity and anisotropy of composite structures. The induced defects reduce integrity of the machined surface as well as the loading capacity of the composite structure in service. Therefore, it is necessary to quantify the damage induced during trimming and correlate the quality of the machined surface to mechanical properties. The correlation of the surface roughness criteria, widely used in literature, to the mechanical behavior raise several contradictions. For this reason, new parameters for the characterization of the machined surface are proposed and correlated to the mechanical behavior under compressive loading. In this context, carbon fiber-reinforced plastic laminates are conventionally trimmed, and the machining damage is characterized using scanning electron microscope observations, X-ray tomography, and 3D optical topography. The results reveal that crater volume and maximum depth of damage quantify the machining damage more realistic compared to the classical surface roughness criteria.

Authors: Strudwick Katie
Published: October 2019

This article discusses the development and good practice of an undergraduate collaborative partnership module between police practitioners and academics meeting the challenges for teaching partnerships within higher education. Through innovative curriculum design and the application of the Student as Producer model, the article considers aspects of student engagement, ownership of learning journeys and shared dialogues. The case study was developed to strengthen existing productive links with policing and offer real-life collaboration on contemporary police studies. The module has impacted on student learning and has institutionally embraced professional practice in teaching through designing ‘academic practice as learning’.
Achieving Immersion in the Tourism Experience: The Role of Autonomy, Temporal Dissociation, and Reactance
Authors: Lunardo Renaud , Ponsignon Frédéric
Published: October 2019

In the past two decades, research in tourism has explored the shift to the experiential economy in which consumers (visitors) seek memorable experiences. While prior studies converge toward the idea that immersion is a critical dimension of the tourism experience, research on immersion remains scarce, particularly the conditions under which immersion is achieved and its consequences on visitor evaluations. To fill this gap, this research builds on the experiential and flow literature to propose a model where immersion derives from autonomy and leads to greater visitor satisfaction through the underlying mechanism of temporal dissociation. Additionally, it is proposed that reactance moderates the relationship between autonomy and temporal dissociation. Two empirical studies—a field study in an experiential wine museum and an experiment involving a zoo visit—provide robust evidence of these effects, fostering theoretical progress on immersion and subsequent temporal dissociation as important dimensions of the tourism experience.
On the Persistence of Social Groups
Authors: Greenwood John D.
Published: October 2019

In this short discussion note, I cast doubt upon the common view that social groups persist throughout changes in their membership, by virtue of the maintenance of their structure and/or function. I offer two counterexamples, and consider two possible responses to a natural objection to them, neither of which support the view that it is a metaphysical truth that social groups persist through changes in their membership, or persist by virtue of the maintenance of their structure and/or function.
Nuclear Energy Safety, Regulatory Independence, and Judicial Deference: The Case of the Atomic Energy Regulatory Board of India
Authors: Ram Mohan M. P. , Gopakumar K. V. , Smith Tyson
Published: October 2019

Research examining regulatory independence has either suggested de jure independence to be a predictor of de facto independence or suggested that the presence of de jure may not always indicate de facto independence. We study the Indian Atomic Energy Regulatory Board (AERB) to emphasize how AERB has enjoyed de facto independence, even in the absence of de jure independence. Using “judicial deference” principle, and through a mapping of substantive court cases, the article demonstrates Indian judiciary has consistently applied deference to AERB’s decision-making process, thereby showing confidence in the nuclear regulatory regime sustained as its inception.
Premarital Sexuality, Abortion, and Intergenerational Dynamics in China
Authors: Lai Ruby Y. S. , Choi Susanne Y. P.
Published: October 2019

This article uses premarital abortion(s) as a window to examine diverse parental roles in adult unmarried daughters’ intimate lives in post-socialist China. It also addresses issues of premarital sex, premarital pregnancy, and the emergence of a dating culture. The article identifies four patterns of parent–adult daughter interactions during the decision-making process of premarital abortion: no recognizable parental role, referencing perceived parental views, consulting parents, and direct parental pressure to terminate pregnancy. The findings suggest that within the context of a mature dating culture in urban China and the prevalence of premarital sex, adult daughters have achieved considerable control over decisions about sex and intimacy. Nevertheless, many women have continued to consider parental views on their marriage and reproduction as crucial. Some women have even prioritized the preferences of their parents over those of their intimate partners because they consider intergenerational ties more enduring and reliable than ties between intimate partners.
Coordinated motion control for automated vehicles considering steering and driving force saturations
Authors: Xia Hongyang , Chen Jiqing , Liu Zhaolin , Lan Fengchong
Published: October 2019

Steering angle and driving force saturations are inevitable in autonomous vehicle motions, which will degrade the motion control performance and even deteriorate the driving safety. In addition, the strong coupling of lateral and longitudinal motions of autonomous vehicles also contributes to the saturations damage and increases the control difficulty. To reduce these negative impacts on motion control, a novel motion controller for automated vehicles is presented in this paper. Firstly, an extended 3 degree of freedom vehicle dynamic model is built with the unknown saturations, strong-coupled motion characteristics and external disturbance considered simultaneously. Then, a coordinated controller is designed to complete motion control task based on sliding-mode control (SMC) and non-singular fast terminal sliding-mode control (NFTSM). Moreover, a three-layer radial basis function neural network (RBFNN) is adopted as a compensator to approximate modelling uncertainties. Based on Lyapunov stability theory, the uniform ultimate boundednesses of motion control errors are guaranteed. Simulation results show that the proposed controller owns smaller steady-state errors and faster convergence speed.
Persuasive Quick-Writing about Text: Intervention for Students with Learning Disabilities
Authors: Ciullo Stephen , Mason Linda H. , Judd Laura
Published: October 2019

Researchers examined the effects of self-regulated strategy development (SRSD) to teach students with learning disabilities (LD) to compose persuasive quick-writing about text. The study included a multiple-baseline design with multiple probes for eight students with LD in grades four and five. Researchers observed a functional relationship by systematically replicating the intervention across all student participants. Following SRSD instruction for paraphrasing text and persuasive quick-writing, students increased their persuasive writing outcomes. Improvements were also noted for essay quality and writing length. Implications for future integrated writing and reading interventions are provided.

Authors: Chiesa-Estomba Carlos Miguel , Saga-Gutierrez Carlos , Larruscain Ekhiñe , González-García José Ángel , Sistiaga-Suarez Jon Alexander , Altuna Xabier
Published: October 2019

Introduction:

Twenty percent of the total lithiasis that affect a major salivary gland will be found in the parotid gland. An exclusive sialoendoscopic approach has achieved success rates close to 80%. In a significant percentage of these remaining cases, combined transfacial approaches assisted by sialendoscopy are presented as an option to be taken into account.

Patients and Methods:

A prospective analysis of cases treated by combined transfacial approach assisted by sialendoscopy for lithiasis of the parotid gland and the impact of the facial nerve stimulator used during surgery.

Results:

Five patients were included; all of them operated satisfactorily. In 4 of them, the approach proposed by McGurk and modified by Capaccio was used, and in 1 of them, the approach proposed by Nahlieli was used. We suffered a complication in just case due to the appearance of postoperative sialocele.

Conclusion:

According to our results and those previously published, the transfacial approach assisted by sialendoscopy can be considered a useful technique. Proper planning ensures an optimal result in the treatment of parotid gland lithiasis. The use of facial nerve stimulator guarantees extra security when working near to a branch of the facial nerve is suspected.
Lobbying the Client: The role of policy intermediaries in corporate political activity
Authors: Tyllström Anna , Murray John
Published: October 2019

Traditionally, CPA scholarship has either assumed away policy intermediaries completely, or depicted them as corporate mouthpieces. Meanwhile, research on policy intermediaries has portrayed actors such as think tanks, PR firms and lobbying firms as far more active and self-interested. Our study investigates this puzzle by attending to the question: ‘Whose political agenda is expressed by intermediaries during their lobbying on behalf of corporate clients?’ By importing insights from studies of policy intermediaries, and approaching the world of lobbying qualitatively – delving deep into the ‘how’ and ‘why’ of corporate lobbying using ethnographic field data and interviews with corporate lobbyists – we provide a different, more fine-grained picture of the lobbyist–client relationship, in which policy intermediaries shape, adapt and even invent their clients’ agendas. Our study contributes CPA scholarship by (1) providing an analytical distinction between the political agendas of corporate clients and those of their lobbyists, (2) bringing further detail and modification to Barley’s theory of an institutional field of political influence and (3) identifying agency problems between client and lobbyist as a novel explanation for why the financial profitability of CPA investment has been difficult to verify. Moreover, the study brings further sophistication to a burgeoning literature on policy intermediaries by suggesting that lobbyists’ own professional characteristics – such as length of political experience and strength of political convictions – influence how independently of their clients they dare to act.
Practice makes voters? Effects of student mock elections on turnout
Authors: Öhrvall Richard , Oskarsson Sven
Published: October 2019

Student mock elections are conducted in schools around the world in an effort to increase political interest and efficacy among students. There is, however, a lack of research on whether mock elections in schools enhance voter turnout in real elections. In this article, we examine whether the propensity to vote in Swedish elections is higher among young people who have previously experienced a student mock election. The analysis is based on unique administrative population-wide data on turnout in the Swedish 2010 parliamentary election and the 2009 European Parliament election. Our results show that having experienced a mock election as a student does not increase the likelihood of voting in subsequent real elections. This result holds when we study both short- and long-term effects, and when we divide our sample into different parts depending on their socio-economic status and study each part separately.
Evaluating the effectiveness of aquatic therapy on mobility, balance, and level of functional independence in stroke rehabilitation: a systematic review and meta-analysis
Authors: Iliescu Alice Mary , McIntyre Amanda , Wiener Joshua , Iruthayarajah Jerome , Lee Andrea , Caughlin Sarah , Teasell Robert
Published: October 2019

Objective:

To meta-analyze and systematically review the effectiveness of aquatic therapy in improving mobility, balance, and functional independence after stroke.

Data Sources:

Articles published in Medline, Embase, CINAHL, PsycINFO, and Scopus up to 20 August 2019.

Study Selection:

Studies met the following inclusion criteria: (1) English, (2) adult stroke population, (3) randomized or non-randomized prospectively controlled trial (RCT or PCT, respectively) study design, (4) the experimental group received >1 session of aquatic therapy, and (5) included a clinical outcome measure of mobility, balance, or functional independence.

Data Extraction:

Participant characteristics, treatment protocols, between-group outcomes, point measures, and measures of variability were extracted. Methodological quality was assessed using Physiotherapy Evidence Database (PEDro) tool, and pooled mean differences (MD) ± standard error and 95% confidence intervals (CI) were calculated for Functional Reach Test (FRT), Timed Up and Go Test (TUG), gait speed, and Berg Balance Scale (BBS).

Data Synthesis:

Nineteen studies (17 RCTs and 2 PCTs) with a mean sample size of 36 participants and mean PEDro score of 5.6 (range 4–8) were included. Aquatic therapy demonstrated statistically significant improvements over land therapy on FRT (MD = 3.511 ± 1.597; 95% CI: 0.381–6.642; P = 0.028), TUG (MD = 2.229 ± 0.513; 95% CI: 1.224–3.234; P < 0.001), gait speed (MD = 0.049 ± 0.023; 95% CI: 0.005–0.094; P = 0.030), and BBS (MD = 2.252 ± 0.552; 95% CI: 1.171–3.334; P < 0.001).

Conclusions:

While the effect of aquatic therapy on mobility and balance is statistically significant compared to land-based therapy, the clinical significance is less clear, highly variable, and outcome measure dependent.
Achieving Scaled and Sustained Use of Client-Based Projects in Business School Marketing Education: A Proposed Suprastructure
Authors: Shanahan Doreen E. , Palmer Lynda H. , Salas Jim
Published: October 2019

Business scholars agree that well-constructed experiential learning and specifically client-based projects (CBPs) provide an opportunity for students to apply concepts they learn to solve particular problems. As an additional outcome, they provide value for multiple stakeholders including the client, business community, university, and the instructor. However, CBPs can be inherently complex and demanding on instructors, impeding adoption and sustained use. As critical participatory action researchers, we worked collaboratively with faculty within our marketing department to examine and address the challenges of scaling capacity to support, effectively replicate, and grow use of CBPs in our business school marketing courses and subsequently other department curriculum. This article describes a unified view of project management and business development processes as a framework for effective scaled use of CBPs and outlines a suprastructure. It additionally offers “how to” guidance that can support use of a suprastructure as a means of achieving economies of scale, including description of roles and relationships.
Hand–object configuration estimation using particle filters for dexterous in-hand manipulation
Authors: Hang Kaiyu , Bircher Walter G. , Morgan Andrew S. , Dollar Aaron M.
Published: October 2019

We consider the problem of in-hand dexterous manipulation with a focus on unknown or uncertain hand–object parameters, such as hand configuration, object pose within hand, and contact positions. In particular, in this work we formulate a generic framework for hand–object configuration estimation using underactuated hands as an example. Owing to the passive reconfigurability and the lack of encoders in the hand’s joints, it is challenging to estimate, plan, and actively control underactuated manipulation. By modeling the grasp constraints, we present a particle filter-based framework to estimate the hand configuration. Specifically, given an arbitrary grasp, we start by sampling a set of hand configuration hypotheses and then randomly manipulate the object within the hand. While observing the object’s movements as evidence using an external camera, which is not necessarily calibrated with the hand frame, our estimator calculates the likelihood of each hypothesis to iteratively estimate the hand configuration. Once converged, the estimator is used to track the hand configuration in real time for future manipulations. Thereafter, we develop an algorithm to precisely plan and control the underactuated manipulation to move the grasped object to desired poses. In contrast to most other dexterous manipulation approaches, our framework does not require any tactile sensing or joint encoders, and can directly operate on any novel objects, without requiring a model of the object a priori. We implemented our framework on both the Yale Model O hand and the Yale T42 hand. The results show that the estimation is accurate for different objects, and that the framework can be easily adapted across different underactuated hand models. In the end, we evaluated our planning and control algorithm with handwriting tasks, and demonstrated the effectiveness of the proposed framework.
‘Stand back and watch us’: Post-capitalist practices in the maker movement
Authors: Smith Thomas S.J.
Published: October 2019

This paper examines the economic practices of maker spaces – open workshops that have increased in number over recent years and that aim to provide access to tools, materials and skills for small-scale manufacturing and repair. Scholarly interest in such spaces has been increasing across the social sciences more broadly, parallel to a growing interest in craft and making in economic geography. However, to rectify the ‘capitalocentrism’ of much existing work, the paper examines the case of a workshop in Edinburgh, Scotland, through the dual theoretical lens of diverse economies and social practice theory. This conceptual approach sees the space as a novel form of economic ‘being-in-common’, providing diverse and contradictory opportunities for post-capitalist practice. The paper draws conclusions regarding the limits and potential of such spaces for sowing the prefigurative seeds for a more inclusive, sustainable and democratic urbanism.
Gender Equity and Vitamin A Supplementation: Moving Beyond Equal Coverage
Authors: Nordhagen Stella , Bauck Aubrey , Doledec David
Published: October 2019

Background:

Vitamin A supplementation (VAS) is currently implemented in over 80 countries worldwide, but little attention has been paid to gender equity in the design or implementation of these programs.

Objective:

This article describes the ways in which gender equity can impact or be impacted by VAS programs and suggests ways to ensure these programs better support gender equity in the future.

Methods:

We undertook a desk review of research on gender equity in health services and extrapolated findings to VAS, highlighting gender equity issues throughout the VAS implementation process and across delivery platform types. We also amassed secondary data on VAS coverage from 45 surveys in 13 countries and analyzed it to examine differences in VAS coverage between boys and girls.

Results:

Despite few significant differences in coverage between boys and girls, we identify numerous ways in which gender equity can impact or be impacted by VAS programs, including through the choice of VAS distributors and the communication materials used to promote VAS campaigns. Examining these different entry points reveals that there are several missed opportunities for better integration of gender within VAS.

Conclusions:

VAS program implementers and policymakers should revisit VAS approaches to identify opportunities for advancing gender equity through this wide-reaching platform.
Endovascular therapy for hemodialysis patients with atrial fibrillation and cerebral thromboembolism: A case series
Authors: Kamijo Masafumi , Hayashi Waka , Otsuka Emiko , Obata Yoko , Sahara Noriyuki , Takemoto Koichiro , Sakamoto Seisaburo , Ueki Yukitaka , Nishino Tomoya
Published: October 2019

Introduction:

Hemodialysis patients with atrial fibrillation are at high risk for stroke. Intravenous recombinant tissue plasminogen activator is considered for acute ischemic stroke. However, recombinant tissue plasminogen activator therapy is contraindicated for some hemodialysis patients with atrial fibrillation. These patients and those who have received recombinant tissue plasminogen activator therapy without blood flow recovery are candidates for endovascular therapy.

Methods and results:

Three hemodialysis patients with atrial fibrillation received endovascular therapy for acute cerebral infarction. Cerebrovascular incident occurred during or after hemodialysis in two of these patients. All three patients achieved successful recanalization after endovascular therapy.

Conclusion:

In this series, endovascular therapy showed good results without complications. More cases should be investigated to obtain more evidence of successful endovascular therapy for hemodialysis patients.
#rebel: Rebel communication strategies in the age of social media
Authors: Loyle Cyanne E , Bestvater Samuel E
Published: October 2019

How have rebel communication strategies been shaped by the increasingly social nature of the internet and the constant changes of information and communication technology in a Web 2.0 world? Rebel groups’ ability to disseminate a message has previously been constrained by the size of the audience they could reach through traditional technologies and the costs of those technologies. Emerging social internet platforms change this dynamic by providing rebel groups with new opportunities to build and communicate to an audience. Scholars have theorized about how rebel groups adapt to these new opportunities, but to date, little systematic analysis into the phenomenon has been conducted. In this project, we present a new dataset on rebel group Twitter use and use the data to examine how armed groups use social media to communicate, the topics contained in those communications, and the audiences that consume them. Through a richer understanding of the ways in which rebel groups communicate we are better able to measure the impact of new information technologies on armed conflict in the future.
