Published: May 2021

AbstractIn this paper, we extend to the function field setting the heuristics formerly developed by Conrey, Farmer, Keating, Rubinstein and Snaith, for the integral moments of L-functions. We also adapt to the function field setting the heuristics first developed by Conrey, Farmer and Zirnbauer to the study of mean values of ratios of L-functions. Specifically, the focus of this paper is on the family of quadratic Dirichlet L-functions $$L(s,\chi _{P})$$

Abstract
Background
Women with aesthetic prostheses must be included in the target population of mammography screening programmes. Breast implants are radiopaque and partially obscure the breast tissue. This can be avoided with the use of the Eklund technique, which causes an increased radiation exposure. In this study, augmented women undergoing a dedicated protocol within a population-based screening programme were compared according to selected indicators with the standard screening population. Essential dosimetric parameters and their time trend were also assessed.

Materials and methods
The study was conducted in a screening centre in Milan in the years 2009–2016. The screening protocol for women with breast implants included a double-read mammography with the Eklund views, ultrasound and clinical breast examination.

Results
A total of 28,794 women were enrolled, including 588 (2%) women with breast implants and 28,206 (98%) undergoing the standard screening protocol. The invasive assessment rate was 9.0‰ for women with breast implants vs. 15‰ in the standard cohort. The surgical referral rate was 2.2% vs. 0.9%. The detection rate was similar in the two groups (4.0 and 4.5‰, respectively). There were significant differences in the average glandular dose according to the mammography equipment. The use of the Eklund views increased over time.

Conclusions
Screening of augmented women according to a specific protocol in the contexts of population-based programmes is feasible. Observed differences in screening indicators relative to the standard screening population require further research. The increasing use of Eklund views probably results from quality assurance measures associated with screening programmes.
Fatigue Strength of Rivet Resistance Spot Welding Technique in Comparison with Self-Piercing Riveting for Multi-material Body-in-White Structure
Authors: Heidrich Daniel , Zhang Fan , Fang Xiangfan 
Published: May 2021

AbstractCost-efficient multi-material design requires suitable joining techniques, ideally with low investment cost by re-using existing assembling lines. The recently developed resistance rivet spot welding (RRSW) technique combines mechanical joining with spot welding and enables cost-efficient joining of aluminum (Al) to steel for multi-material body-in-white structures. Here, the static and fatigue strengths of different hybrid Al-steel specimens made by RRSW were measured and compared to other state-of-the-art joining techniques, such as self-piercing riveting (SPR) and RSW. The static strength of RRSW matched or exceeded that of SPR regardless of the sheet thickness, whereas the fatigue strength of the RRSW joints showed a strong dependency on the thickness of the steel sheets. For thinner steel sheets, the fatigue of the RRSW-joined metal sheets was lower in comparison with SPR. Fatigue cracks were initiated in thin steel sheets around the weld nugget. By contrast, for thicker steel sheets, the fatigue strength of RRSW matched or exceeded that of SPR. With a thicker material combination of 1.5 mm steel and 1.0 mm Al, fatigue cracks occurred only in the Al sheet in both SPR and RRSW. For suitable steel sheet thickness, RRSW is thus a durable technique to join steel and Al.
CIP2A silencing alleviates doxorubicin resistance in MCF7/ADR cells through activating PP2A and autophagy
Authors: Zhu Z. , Wei Z. 
Published: May 2021

Abstract
Background
Cancerous inhibitor of protein phosphatase 2A (CIP2A) plays a critical role in the pathogenesis of various types of cancer. Here, we investigated whether manipulating CIP2A abundance could enhance the treatment effects of doxorubicin in MCF-7/ADR cells.

Methods
CIP2A silencing was achieved by specific siRNAs. Proliferation of breast cancer cell line MCF-7/ADR under effective doxorubicin concentrations after CIP2A silencing was examined by MTT assay. Wound healing assay was performed to quantify cell migration and caspase-3/-7 activities were measured for assessing the extent of apoptosis.

Results
First, our data confirmed that MCF-7/ADR cell proliferation was suppressed by doxorubicin in a dose-dependent manner. Additionally, knocking down of CIP2A could further decrease MCF-7 cell proliferation and migration, even in the presence of doxorubicin. Mechanistically, we have found that CIP2A silencing promoted cell apoptosis relative to doxorubicin alone or vehicle control groups. Lastly, phosphatase2A (PP2A) activity was potentiated and the autophagy markers, LC3B and Beclin1, were upregulated after knocking down CIP2A.

Conclusion
Our findings support the potential benefits of using CIP2A inhibitor as a therapeutic agent to treat doxorubicin-resistant breast cancer.

Italian adolescents’ understandings of globalization
Authors: Ginevra Maria Cristina , Di Maggio Ilaria , Santilli Sara , Nota Laura 
Published: May 2021

ABSTRACTIntroductionHaving a clear understanding of the concept of globalization can be particularly relevant for adolescents to comprehend how the world functions and to reflect on the way their personal and professional identity and career future might be affected by globalization. Thus, this mixed design study aimed at examining Northeastern Italian adolescents’ thinking about globalization and at exploring the potential role of education (the type of school) in conceptualizing globalization.MethodsA total of 163 Italian adolescents (42.3% boys and 57.5% girls) aged 16–19 years, attending a scientific lyceum or a commercial, technological, or professional high school participated in the study. Participants were invited to explain the concept of globalization. Their answers were analyzed using a thematic analysis procedure.Results& Conclusions:. The analyses revealed adolescents’ limited and inaccurate understandings of globalization, with almost exclusive emphasis on the positive aspects of globalization, and without a critical understanding of its consequences. Moreover, no differences related to their educational experience (the type of school they attended) or socio‐economic status emerged when reporting their understanding of globalization. The results suggested the relevance of a training process for the promotion of critical thinking, especially in the field of career guidance.
Delinquency as a consequence of parental warmth and self‐efficacy: Total sample and individual male and female mediation analyses
Authors: Walters Glenn D. 
Published: May 2021

ABSTRACTIntroductionThis study's purpose was to investigate the mediating effect of parental control self‐efficacy on the parental warmth → child delinquency relationship in the mothers and fathers of early to mid‐adolescent youth in a test of performance accomplishments as a prelude to parental self‐efficacy.MethodsParental warmth and control self‐efficacy estimates, representing parental support and control, respectively, were provided by the mothers and fathers of 3934 (2010 boys, 1924 girls) youth from the Longitudinal Study of Australian Children (LSAC) and self‐reported delinquency was obtained from the child.ResultsAs predicted, parental control self‐efficacy mediated the relationship between parental warmth and child delinquency, whereas parental warmth did not mediate the relationship between parental self‐efficacy and child delinquency. When analyses were performed separately for boys and girls, the father warmth → father self‐efficacy → child delinquency pathway achieved the most consistent results in boys and the mother warmth → mother self‐efficacy → child delinquency pathway achieved the only significant effect in girls.ConclusionsThese results suggest that performance accomplishments, as characterized by a warm parent–child relationship, led to enhanced parental control self‐efficacy, which, in turn, served to inhibit future delinquency in the child, thereby lending credence to a social cognitive learning theory interpretation of the parental support–control interface.

AbstractObjective:Community responses are important for the management of early-phase outbreaks of coronavirus disease 2019 (COVID-19). Perceived susceptibility and severity are considered key elements that motivate people to adopt nonpharmaceutical interventions. This study aimed to (i) explore perceived susceptibility and severity of the COVID-19 pandemic, (ii) examine the practice of nonpharmaceutical interventions, and (iii) assess the potential association of perceived COVID-19 susceptibility and severity with the practice of nonpharmaceutical interventions among people living in Afghanistan.Methods:A cross-sectional design was used, using online surveys disseminated from April to May 2020. Convenience sampling was used to recruit the participants of this study. The previously developed scales were used to assess the participants’ demographic information, perceived risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and perceived severity of COVID-19. Multivariate analyses were conducted to assess the potential association of perceived COVID-19 susceptibility and severity with the practice of nonpharmaceutical interventions.Results:The Internet was the main source for obtaining COVID-19 information among participants in this study. While 45.8% of the participants believed it was “very unlikely” for them to get infected with COVID-19, 76.7% perceived COVID-19 as a severe disease. Similarly, 37.5% believed the chance of being cured if infected with COVID-19 is “unlikely/very unlikely.” The majority of participants (95.6%) perceived their health to be in “good” and “very good” status. Overall, 74.2% mentioned that they stopped visiting public places, 49.7% started using gloves, and 70.4% started wearing a mask. Participants who believed they have a low probability of survival if infected with COVID-19 were more likely to wear masks and practice hand washing.Conclusions:It appears that communities’ psychological and behavioral responses were affected by the early phase of the COVID-19 pandemic in Afghanistan, especially among young Internet users. The findings gained from a timely behavioral assessment of the community might be useful to develop interventions and risk communication strategies in epidemics within and beyond COVID-19.
Assessment of New York City Urgent Care Centers’ Emergency Preparedness and Infection Prevention and Control Practices, 2016–2017
Authors: Jacobs-Wingo Jasmine , Beatty Norman L , Jang Kristine , Foote Mary MK 
Published: May 2021

AbstractBackground:Urgent care centers (UCCs) have become frontline healthcare facilities for individuals with acute infectious diseases. Additionally, UCCs could potentially support the healthcare system response during a public health emergency. Investigators sought to assess NYC UCCs’ implementation of nationally-recommended IPC and EP practices.Methods:Investigators identified 199 eligible UCCs based on criteria defined by the Urgent Care Association of America. Multiple facilities under the same ownership were considered a network. As part of a cross-sectional analysis, an electronic survey was sent to UCC representatives assessing their respective facilities’ IPC and EP practices. Representatives of urgent care networks responded on behalf of all UCCs within the network if all sites within the network used the same policies and procedures.Results:Of the respondents, 18 representing 144 UCCs completed the survey. Of these, 8 of them (44.4% of the respondents) represented more than 1 facility that utilized standardized practices (range = 2-60 facilities). Overall, 81.3% have written IPC policies, 75.0% have EP policies, 80.6% require staff to train on IPC, and 75.7% train staff on EP.Conclusion:Most UCCs reported implementation of IPC and EP practices; however, the comprehensiveness of these activities varied across UCCs. Public health can better prepare the healthcare system by engaging UCCs in planning and executing of IPC and EP-related initiatives.

Published: May 2021

AbstractBackground:Emergency nurses play a major role in disaster relief in mainland China, but there is no valid instrument to measure the extent of their disaster preparedness. The Disaster Preparedness Evaluation Tool© is a reliable instrument to assess the disaster preparedness of nurse practitioners. The tool has been translated and validated in Saudi Arabia, Taiwan, China and the United States of America.Objectives:This study aimed at translating and adapting the Disaster Preparedness Evaluation Tool© (DPET) for emergency nurses in mainland China and determining its psychometric properties.Design, Settings and Participants:A total of 2 cross-sectional online surveys were conducted in the emergency departments of 26 public grade III-A hospitals in Guangdong, mainland China. In the first study, 633 emergency nurses were recruited from May to August, 2018. In the second study, 205 were recruited in April 2019.Methods:The instrument was adapted through rigorous forward-backward translation, face validity, and pre-test processes. Exploratory factor and parallel analyses were used in the first study. Confirmatory factor analysis, internal consistency and split-half reliability were used in the second study.Results:Exploratory factor and parallel analyses extracted a 5-factor solution comprising of 34 items that accounted for 64.06% of the total variance. The fit indices indicated a good model fit. The reliability was good, as indicated by a Cronbach’s alpha of 0.97 and a split-half reliability coefficient of 0.97.Conclusion:The mainland China version of the DPET (DPET-MC) was a reliable and valid instrument and can be used in practice.
Effective Judicial Protection and Mutual Recognition in the European Administrative Space
Authors: Arroyo Jiménez Luis 
Published: May 2021

AbstractThe right to effective judicial protection is driving to a significant evolution of EU administrative law, especially in view of the multijurisdictional nature of the European administrative structure. This Article focuses on gaps in judicial protection arising from mutual recognition in transnational interactions between the administrative authorities of the EU’s Member States. It first sets the ground by examining the ingredients of the equation: The fundamental right to effective judicial protection, the concept and forms of mutual recognition, and the notion of European administrative space. Next, this Article assesses the judicial protection that private parties can obtain from national courts in these transnational scenarios. Procedure, substance, and deference are separately explored here, in order to draw out blind spots and deficiencies, as well as to suggest possible solutions to address at least some of them. This Article ends with a brief summary of the main findings.
Judicial and Extra-Judicial Challenges in the EU Multi- and Cross-Level Administrative Framework
Authors: Eliantonio Mariolina , Vogiatzis Nikos 
Published: May 2021

AbstractThis Special Issue aims at interrogating the judicial and extra-judicial challenges that arise from the EU complex administrative framework, which can be characterized as both multi-level—arising from the vertical cooperation between EU and national authorities—and cross-level—arising from horizontal cooperation between national authorities themselves. It starts from the premise that there may be decisions affecting natural and legal persons which cannot be easily reviewed judicially, whereas in extra-judicial cooperation, the lack of common standards or practices across Member States may undermine the effectiveness of EU policies and objectives. This Special Issue focuses on various mechanisms of horizontal and vertical cooperation, such as regulatory patterns giving rise to transnational administrative acts and mutual recognition systems, case studies of composite procedures in the field of the genetically modified organisms regime and information sharing in asylum policy, as well as multi-level inspection activities for the enforcement of EU law. It further complements the analysis on the judicial challenges arising from those cooperative structures with an examination of extra-judicial avenues of control in the EU administrative framework, namely the “EU queries” process and the cooperation of ombud offices, as well as the audit of the EU budget. This Special Issue reflects on ways to overcome the current challenges of, and seeks to prompt further research on, the multi-layered EU system of administrative cooperation.
Storied Social Change: Recovering Jane Addams's Early Model of Constituent Storytelling to Navigate the Practical Challenges of Speaking for Others
Authors: Fenton Jennifer Kiefer 
Published: May 2021

AbstractThis essay recovers Jane Addams's (1860–1935) practice of constituent storytelling as a resource for contemporary social-change-nonprofit professional practice and activism. Whereas feminist theorizing is rich with resources for theorizing about constituent storytelling, Addams, as both a publicly engaged philosopher and a social-change-nonprofit professional, is uniquely situated to provide practical ways forward for social-change practitioners navigating the lived complexities of speaking for others in light of spatial stratification, subordinating structures, and epistemic exclusion. As a hybrid activist-scholar situated across diverse spaces, Addams serves as a bridge between feminist theorizing about speaking for others, and practices of it among social-change-nonprofit professionals and activists. I show that Addams reveals new ways of thinking about the practice of constituent storytelling for social-change-nonprofit professionals. Namely, in this lived context, speaking for others entails speaking for them through one's own story. Responsible constituent storytelling names oneself as a speaker, owns one's own social standpoint in this rhetorical naming practice, and orients the story through one's own journey—a journey inevitably riddled with failures and faulty assumptions—toward democratic neighborship with the Other across difference.
Party–group interactions in Southern Europe: evidence from an expert survey
Authors: Lisi Marco 
Published: May 2021

AbstractDespite the development of empirical research on the relations between parties and interest groups, the topic is still understudied and presents several shortcomings. On the one hand, this relationship has been studied mostly from the political parties' point of view. On the other, there is a lack of consensus regarding the determinants of party–group connection. This study aims to advance our knowledge on the topic by examining the relationship between interest groups and political parties in Southern European countries (Greece, Italy, Portugal, and Spain). By relying on new data collected through an expert survey, we focus specifically on the strength of the linkage established between parties and interest groups, as well as their determinants. The results suggest that there is a great variation in party–group links, which is explained mostly by party characteristics, namely the type of parties, ideology, and their electoral strength.
OPPOSITION REPERTOIRES UNDER AUTHORITARIAN RULE: VIETNAM'S 2016 SELF-NOMINATION MOVEMENT
Authors: Truong Nhu 
Published: May 2021

AbstractCivil society actors collectively organized online and offline to nominate themselves and oppose the Vietnamese Communist Party in the 2016 legislative election. The level of opposition coordination among these independent self-nominees exceeded and qualitatively differed from previous atomized attempts in the 2011 election. External shifts in the political opportunity structure offer only a partial explanation for the increased coordination among independent candidates in Vietnam's 2016 self-nomination movement. In this article, I theorize that it is the combination of both opportunity structure and overlapping linkages across spheres of social contention and civil society, all accumulated from a prior history of protests and activism, that provide the conditions for the emergence of independent self-nominees and opposition coordination in single-party-elections. In Vietnam, a cumulative process of participation in social contention and civil society organizations during 2011 to 2016 allowed actors to develop linkages that strengthened their repertoires of contention and resonant frames of collective action. These linkages, combined with favorable political opportunities, effectively facilitated greater mobilization and coordination among independent self-nominees in the 2016 election.
