Quality Signaling Through Crowdfunding Pricing
Authors: Bolandifar Ehsan , Chen Zhong , Kouvelis Panos , Zhou Weihua 
Published: January 2023

Problem definition: This paper studies an entrepreneur’s pricing strategy in a reward-based crowdfunding campaign under asymmetric product quality information. We propose two signaling mechanisms and investigate how entrepreneurs can leverage their pricing strategy to signal a high-quality project. Academic/practical relevance: This problem is relevant to practice, as asymmetric quality information is a significant concern in reward-based crowdfunding. High-quality entrepreneurs seek credible mechanisms to signal the quality of projects to customers. Methodology: We develop a stylized game-theoretic signaling model with funding and regular selling periods that captures asymmetric quality information between an entrepreneur and customers. Results: We propose a new theory on quality signaling in crowdfunding. We show that contingent access to the regular selling market after running a successful crowdfunding campaign allows high-quality entrepreneurs to signal their quality through low funding prices (one-price signaling). A high-quality entrepreneur can increase his funding price and still signal his high-quality level if he commits to the future regular selling price (two-price signaling). We show that the distinct feature of crowdfunding, that is, the probabilistic nature of crowdfunding, plays different roles in one- and two-price signaling. It is the driving force for the separating equilibrium in one-price signaling, and in two-price signaling, it affects how the entrepreneur should manipulate his funding and regular selling prices to reduce signaling cost. Managerial implications: Entrepreneurs should be mindful of pricing in funding and regular selling periods because it could play an essential role in signaling quality information. Our findings suggest practical tools for quality signaling in crowdfunding. We also investigate when price commitment is the most beneficial for a high-quality entrepreneur, looking for potential signaling mechanisms. Funding: W.

Introduction
Authors: Huss Ephrat 
Published: January 2023

The connection between arts and social work is a rapidly developing area. However, the specific advantages of arts-based research for social work have yet to be articulated. In research in general, arts are defined as less important than words, or numbers – a leitmotif, or illustration (Martinez-Brawley et al., 1997). Often ‘art’ is experienced as the opposite of ‘science’ and thus the opposite of ‘evidence’. In social work specifically, arts are experienced as a luxury, an illustration rather than content, peripheral rather than the ‘on the ground’ problems that social work deals with. Often social workers feel that they have not been trained in the arts and so cannot use it. This is based on a misunderstanding of what social art is. Indeed, arts-based research is most traditionally connected to education, where the use of images is a natural language for children (Eisner, 1997). Of late, however, we see a ‘visual turn’ in social sciences in general, and also in social work practice and research. This includes the use of community art, Photovoice, outsider art, arts for social change, arts and health, arts to humanise institutions, de-stigmatise minorities, and to give voice to silenced groups (Chamberlyne & Smith, 2008; Huss, 2012, Huss & Bos, 2019). This has extended the use of arts-based research in social work. This book aims to capture this promising process. It will show how arts-based research is in fact an especially effective methodology to embody, and will articulate many of the epistemological aims of, social work research.
Using photography to research the ‘other’: the validity of photography for social work research – a visual case study from China
Authors: Szto Peter 
Published: January 2023

This chapter will examine the role of arts-based approaches for social work research. Art is understood as the human impulse to express ideas, emotions, and experience through various forms such as painting, music, architecture, or poetry. The art seeks to reflect and convey cultural sensibilities, a spiritual zeitgeist, and artistic meaning. Art is important because the dominant discourse in social work research has privileged positivist-framed data to explain human experiences. Seeking to understand why social work education has largely ignored art as a tool of research that motivates his chapter. The art form of photography, in particular, is highlighted as a reliable and valid tool of social work research. Its advantages and disadvantages are examined based on the premise that seeing is critical to what one is trying to ameliorate. A case study based on in vivo field research in China is discussed to demonstrate the value of photographic inquiry. Specifically, China’s floating population – the mass internal migration of Chinese labourers from rural to urban areas – is studied as an unprecedented socio-cultural phenomenon in need of a social work response. A visual study is appropriate to clearly see the floating population for its mitigation.
Murals and photography in community engagement and assessment
Authors: Feen-Calligan Holly , Barton Elizabeth , Moreno Julie , Buzzard Emma , Jackson Marion 
Published: January 2023

This chapter describes how photography and mural methods help promote cross-disciplinary and community collaboration, enhance the experience of individual participants as well as that of the community, document university–community projects, and assess outcomes through constituent voices (film), photographs, and mural painting processes. Arts-based research methods and their applications for social work are exemplified by a project of an urban research university’s community engagement program: ArtsCorps.
a/r/tography, rhizomatic storytelling, and ripple effects mapping: a combined arts-based and community mapping methodology to evaluate the impact of COVID-19 expressive arts support groups for frontliners in the Philippines
Authors: Alfonso Maria Regina A. , Lagmay Adrienne M. Santos , Atayde Joey A. , Bautista Kathleen , Lukban M. Imelda 
Published: January 2023

The oppressive arrival of COVID-19 has had a significant socio-economic impact particularly on low- to middle-income families in the Philippines, leading to a plethora of mental health issues that exacerbate family living conditions. Psychosocial support has been a great need. Magis Creative Spaces, in partnership with ABJ Foundation, implemented an initiative to provide Duyan (‘cradle’ in English) groups: free online expressive arts-based psychosocial support groups for various groups of frontline workers. Focusing on the education, health care, and social welfare sectors, a total of 180 participants took part. In parallel, Magis also initiated a research project to document this initiative. A pool of ten facilitators was arranged in pairs to create a team for each Duyan support group. A general sample of each session’s process is as follows: (1) a moment of stillness and silence to offer prayers of healing and gratitude; (2) the introduction of facilitators and participants; (3) a grounding exercise; (4) an art activity (visual art, movement, music or a combination); (5) sharing and discussion; (6) discussion and questions; (7) group photo; (8) closing. Co-authors Alfonso and Atayde, supervising clinicians for the project, organised all stakeholders of the initiative and reviewed key components of the programme. After each of the Duyan support groups were completed, all facilitators were involved in a post-Duyan session group process to harvest stories through drawing and storytelling.
Introduction: Race, Illiberalism, Central Europe
Authors: Kalmar Ivan 
Published: January 2023

Illiberalism in Central Europe is not due to local cultural traditions. Rather, it is a misguided reaction to the way the area was incorporated, after the fall of communism, into global, Western-dominated geopolitical networks. In the Introduction, I discuss the basic concepts of race and illiberalism, as well as the ever-changing nature and definition of Central Europe. I also introduce some of the major personalities promoting illiberalism in the area.
Lived experience of young people with epilepsy in Bahir Dar city government hospitals, Ethiopia, a qualitative interview study
Authors: Ayele Kokeb , Wondiye Habtamu , Bogale Eyob Ketema 
Published: January 2023

Background
Epilepsy is the most common neurological disorder, which is characterized by persistent derangement of the nervous system due to an abrupt excessive discharge of the group of neurons from the cerebrum. For developing young people with epilepsy coping with the challenges of living with epilepsy and adjusting normative tasks associated with adolescence is stressful in all domains of the lives of young people with epilepsy. But in Ethiopia, published literature regarding the lived experience of young people with epilepsy is lacking.

Objectives
This study aims to explore lived experience of young people with epilepsy.

Methods
A qualitative interview study was conducted in Bahir Dar city government specialized and referral Hospitals, from February to April, 2021. Using the rule of saturation, a total of 11 study participants (age 12–24) were selected using hetrogenious types of purposive sampling technique. The data were collected through semi structured interviews technique with the aid of audio recorder. Semi-structured interview guide and observation checklist for care context in health facilities were used. The collected data was transcribed word by word and translated conceptually. The Data were analyzed using thematic approach. The credibility, dependability, Conformability and transferability of the study were assured using different techniques such as peer debriefing, member checking; audit Trail, thick description and purposeful sampling. Atlas- ti version7 software was used to facilitate data analysis.

Results
The participants’ narratives revealed two main themes: ‘experiences due epilepsy’ and ‘coping strategies to wards epilepsy’. Experience due to epilepsy’ was described by young people with epilepsy in terms of psychosocial, physical, economical and health care related experiences. They described coping strategies towards epilepsy in terms of finding support from family and society as well as religious institutions and other traditions as copping strategy.

Conclusion
Even though young people with epilepsy had suffered a lot of hurtful experiences, they reported coping strategies towards epilepsy that include support from various sources. These types of findings have implications for social work interventions for young people living with epilepsy.
Influences of altering footstrike pattern and cadence on lower extremity joint coordination and variability among runners with patellofemoral pain
Authors: Liu Yue , Qi Yujie , Song Yanliqing , Feng Li , Wang Lin 
Published: January 2023

Background
Patellofemoral pain (PFP) is a common overuse injury among runners. It is not only a hindrance to the runner’s training, but also to the runner’s quality of life. PFP runners may strategize different running strategies to reduce patellofemoral joint stress, release pain, and improve function.

Purpose
This study aimed to determine the changes in joint coordination and variability under combinations of foot strike pattern and cadence for runners with patellofemoral pain.

Methods
Twenty male runners with PFP performed six running strategies which were two strike patterns named forefoot (FFS) and rearfoot (RFS) accompanied by three running cadences named slow10%, normal, and fast10%. A modified vector coding technique and circular statistics were respectively used to identify the coordination pattern and variability between hip sagittal-knee frontal (HsKf), hip sagittal-knee sagittal (HsKs) and knee transverse-ankle frontal (KtAf) during stance phase. Coordination patterns which were conformed with anatomical motion pattern was classified as mechanically sound, and the distribution frequency of each coordination pattern was quantified.

Results
Switching to FFS, the HsKf couples (p < 0.001, ES = 1.34) and the HsKs couples (p = 0.001, ES = 0.82) displayed significantly greater frequency in mechanically unsound coordination pattern during the initial stance phase. The effect of increasing running cadence on RFS displayed significantly greater frequency in mechanically unsound hip dominancy (p = 0.042, ES = 0.65) and knee dominancy (p = 0.05, ES = 0.70) coordination patterns for HsKf couples as well as for HsKs couples (p = 0.023, ES = 0.86) during the initial stance phase. Combined with FFS and fast10% cadence, HsKs couples showed more hip-dominated mechanical sound coordination pattern (p = 0.002, ES = 1.25). Further, altering footstrike pattern and cadence failed to change the coordination variability.

Conclusions
Changing running cadence (± 10%) combined with transfer strike pattern from RFS to FFS could not increase the distribution frequency in mechanically sound coordination patterns and change coordination variability for PFP runners.

Published: January 2023

Background
The CC genotype of the IFNL4 gene is known to be associated with increased Hepatitis C (HCV) cure rates with interferon-based therapy and may contribute to cure with direct acting antivirals. The Genedrive® IFNL4 is a CE marked Point of Care (PoC) molecular diagnostic test, designed for in vitro diagnostic use to provide rapid, real-time detection of IFNL4 genotype status for SNP rs12979860.

Methods
120 Participants were consented to a substudy comparing IFNL4 genotyping results from a buccal swab analysed on the Genedrive® platform with results generated using the Affymetix UK Biobank array considered to be the gold standard.

Results
Buccal swabs were taken from 120 participants for PoC IFNL4 testing and a whole blood sample for genetic sequencing. Whole blood genotyping vs. buccal swab PoC testing identified 40 (33%), 65 (54%), and 15 (13%) had CC, CT and TT IFNL4 genotype respectively. The Buccal swab PoC identified 38 (32%) CC, 64 (53%) CT and 18 (15%) TT IFNL4 genotype respectively. The sensitivity and specificity of the buccal swab test to detect CC vs non-CC was 90% (95% CI 76–97%) and 98% (95% CI 91–100%) respectively.

Conclusions
The buccal swab test was better at correctly identifying non-CC genotypes than CC genotypes. The high specificity of the Genedrive® assay prevents CT/TT genotypes being mistaken for CC, and could avoid patients being identified as potentially ‘good responders’ to interferon-based therapy.
The effect of contraceptive access reform on privately insured patients: Evidence from Delaware Contraceptive Access Now
Authors: Yoder Maranna , Boudreaux Michel 
Published: January 2023

Background
Many states are implementing comprehensive programs aimed at reducing persistent barriers to contraceptive care. Evidence on the effectiveness of these programs is essential for practice improvement and policy development.

Objective
To evaluate changes in the probability of initiating a contraceptive method by women with employer sponsored insurance after implementation of Delaware Contraceptive Access Now (DelCAN), a statewide initiative that aimed to increase access to long-acting reversible contraceptives (LARCs).

Design, setting, and participants
We used a difference-in-differences design to examine contraceptive initiation rates. Data came from IBM Marketscan and covered women age 15–44 enrolled in employer sponsored insurance. The primary outcome was insertion of a LARC, both in the overall study population and in the immediate postpartum (IPP) setting. Secondary analysis examined changes to other contraceptive method types.

Results
The cohort of 4,550,459 enrollees generated a sample of 11,888,837 person-years and 615,670 childbirth hospitalizations. Difference-in-differences estimates suggested that DelCAN was associated with a 0.3 percentage point (95% CI [0.2, 0.5], p<0.001) increase in the LARC insertion rate in the overall study population and a 0.4 percentage point increase (95% CI [0.2, 0.6], p<0.001) in the percent of births adopting IPP LARC. Associations between DelCAN and LARC insertion appeared stronger for adolescents compared to older women. Results for other method types were less consistent.

Conclusions
A comprehensive statewide program was associated with increased LARC insertion rates among enrollees with employer sponsored insurance. Understanding the effect of these programs is critical for on-going policy development for states engaged in contraceptive access reform.

Published: January 2023

Background
Anticholinergic burden has been associated with adverse outcomes such as falls. To date, no gold standard measure has been identified to assess anticholinergic burden, and no conclusion has been drawn on which of the different measure algorithms best predicts falls in older patients from general practice. This study compared the ability of five measures of anticholinergic burden to predict falls. To account for patients’ individual susceptibility to medications, the added predictive value of typical anticholinergic symptoms was further quantified in this context.

Methods and findings
To predict falls, models were developed and validated based on logistic regression models created using data from two German cluster-randomized controlled trials. The outcome was defined as “≥ 1 fall” vs. “no fall” within a 6-month follow-up period. Data from the RIME study (n = 1,197) were used in model development, and from PRIMUM (n = 502) for external validation. The models were developed step-wise in order to quantify the predictive ability of anticholinergic burden measures, and anticholinergic symptoms. In the development set, 1,015 patients had complete data and 188 (18.5%) experienced ≥ 1 fall within the 6-month follow-up period. The overall predictive value of the five anticholinergic measures was limited, with neither the employed anticholinergic variable (binary / count / burden), nor dose-dependent or dose-independent measures differing significantly in their ability to predict falls. The highest c-statistic was obtained using the German Anticholinergic Burden Score (0.73), whereby the optimism-corrected c-statistic was 0.71 after interval validation using bootstrapping and 0.63 in the external validation. Previous falls and dizziness / vertigo had the strongest prognostic value in all models.

Conclusions
The ability of anticholinergic burden measures to predict falls does not appear to differ significantly, and the added value they contribute to risk classification in fall-prediction models is limited. Previous falls and dizziness / vertigo contributed most to model performance.
Biodegradation of synthetic PVP biofilms using natural materials and nanoparticles

Published: January 2023

Abstract
Biodegradable nanofilms from polyvinyl pyrrolidone (PVP), carboxymethyl cellulose (CMC), citric acid (CA), glycerol (G), and zinc oxide nanoparticles (ZnO-NPs) were prepared using different ZnO concentrations and different electron beam irradiation doses, enabling crosslinking formation. The prepared films were characterized by X-ray diffractometer, Fourier transform infrared spectroscopy, thermogravimetric analyser, and transmission electron microscopy. The swelling percentage of PVP:CMC films was ordered in the sequence of composition ratio 1:2 > 1:1 > 2:1. Results showed decrease in swelling capacity accompanied by increase in gelation percentage of (PVP:CMC)/CA/G)/ZnO nanofilms as the irradiation dose increased up to 20 kGy. The tensile strength of (PVP:CMC) films increased by the incorporation of ZnO-NPs and increasing the irradiation dose. The thermal stability of the prepared (PVP:CMC)/CA/G/ZnO nanofilms was enhanced as the irradiation dosage increased. The water vapour transmission rate of the irradiated films was decreased. The biodegradability of the prepared nanofilms was monitored during 16 weeks and it exceeded 65% weight loss from the original blank weight. Moreover, the nanofilms exhibit antimicrobial activity against fungi, Gram-negative, and Gram-positive bacteria. The broad antimicrobial activity spectrum of the prepared nanofilms increased as the concentration of ZnO-NPs increased. These results suggested that (PVP:CMC)/CA/G/ZnO nanofilms can serve as biodegradable materials in various applications characterized by antimicrobial activity.

Zusammenfassung
Die vorliegende Studie beschäftigt sich mit Agensdemotion und Verfasserreferenz im Deutschen als fremder Wissenschaftssprache. Es wird eine vergleichende Korpusstudie mit deutschsprachigen Masterarbeiten von muttersprachlichen und polnischen Studierenden durchgeführt. Eine quantitative Auswertung ergibt signifikante Unterschiede zwischen den beiden Gruppen. Der Vergleich mit einer vorausgegangenen Studie mit Bachelorarbeiten zeigt aber auch, dass die Unterschiede zwischen L1- und L2-Sprechern und -Sprecherinnen auf Masterniveau geringer werden. Insbesondere seltene Konstruktionen, die auf dem niedrigeren Niveau unterrepräsentiert sind, nähern sich mit steigender Expertise in ihrer Häufigkeit dem L1-Muster an. Fehleranalysen zeigen außerdem auf, dass auch auf dem hohen Niveau der Masterarbeiten noch Einflüsse aus der L1 Polnisch zu erkennen sind.
