The impact of rating classifications on stock prices of Brazilian companies
Authors: Pagin Fernanda , Gomes Matheus da Costa , Antônio Rafael Moreira , Pimenta Júnior Tabajara , Gaio Luiz Eduardo 
Published: May 2021

Purpose
This paper aims to identify if there is an impact of the rating announcements issued by the agencies on the returns of the stocks of Brazilian companies listed on Brasil Bolsa Balcão, from August 2002 to August 2018, identifying which types of announcement (upgrade, downgrade or the same initial classification) cause variations in prices around the date of disclosure of the rating.

Design/methodology/approach
The event study methodology was applied to verify the market reaction around the announcement dates in a 21-day event window (−10, +10). The market model was used to calculate the abnormal returns (ARs), and subsequently, the accumulated ARs.

Findings
The hypotheses tests allowed to verify that the accumulated ARs are different, before and after the three types of rating announcements (upgrades, downgrades and the same classification); in upgrades, the mean of accumulated ARs increases in the days before the event, while in downgrades, this increase occurs after the event. This paper concluded that the rating announcements have an impact on the return of stock of the Brazilian market and that the market reaction occurs most of the time before the event happens, which indicates that the market can anticipate the information contained in the changes in credit ratings.

Practical implications
The results have considerable implications for portfolio managers, institutional investors and traders. It facilitates investment decision-making in the face of rating classification announcements. Market participants can pay more attention to their investment strategies and asset allocation during periods of risk rating announcements. Additionally, traders can understand the form of investment strategy for superior earnings.

Originality/value
The importance of the study is related to the fact that the results may explain the causes of specific movements in the Brazilian financial market related to a source of information that may or may not be able to influence the decisions of the financial agents that operate in this market. The justification is centred on the idea that, for investors who somehow react to the announcements, it is relevant to understand the impact of rating classifications on companies, as access to such information allows for more conscious decision-making.

PurposeTo explore the staffing practices of nurse managers at the unit.Design/methodology/approachIntroduction: Ensuring that units are staffed with adequate nurses to render quality nursing care to clients has become increasingly challenging for most hospitals. There is growing evidence linking best patient outcomes and fewer adverse events to the presence of nurses at the bedside. Hospitals require to attract and retain nurses in the units to address the issues of quality, staff and patient safety. Methods: The study used a descriptive phenomenological design to purposively select 15 nurse managers (NMs) and 47 nurses for in-depth interviews and focus group discussions respectively.FindingsThe study found that the demand for nurses to work in the unit was not scientific. Nurses affirmed their frustration of inadequate numbers of staff in the unit especially, at the periphery hospitals. Time can be used as a source of motivation for nurses and nurses should be involved in the development of the duty roster to enable effective compliance. Compensation for additional duties is relevant in nursing.Research limitations/implicationsThe research was carried only in one region in Ghana, and the findings may not be the same in the other regions.Practical implicationsInadequate staffing level has serious implications on patient safety, quality of care and staff outcomes. This situation necessitates the implementation of health sector staffing norms to ensure the right calibre of mix staff are recruited and retained.Originality/valueThis study is the first in Ghana that we aware of that explore staffing practices at the unit that identifies factors that impact staff schedules for effective care.
Innovation of SME service industry in Indonesia in improving customer satisfaction
Authors: Sanny Lim , Angelina Verencia , Christian Bernando Budi 
Published: May 2021

Purpose
Small-medium enterprise (SME) service industry is an industry that continues to experience growth in developed and developing countries, including Indonesia. SME service industry that engaged in the service industry, namely, rental for generator set, air conditioner and sound system. In recent years, this SME has been experienced in declining in sales and getting some complaints from their customers. Many studies suggest that service quality and customer satisfaction are the key factors in the service industry. The purpose of this paper is to analyze the quality of service based on the customer’s perspective.

Design/methodology/approach
Data was collected using a combination of literature review, interview, brainstorming and questionnaires and analyzed by using importance-performance analysis (IPA) and quality function deployment (QFD) model.

Findings
This research resulted in nine technical requirements that allow the company to focus on these attributes to help the company enhance its customer satisfaction.

Practical implications
Based on the theory, applying service quality, IPA and also QFD will result in customer satisfaction. Practically the enhancement in customer satisfaction is not as easy as expected. Nowadays, customers always expect more and more and it is impossible to fully captured customers’ needs and always satisfy customers. Nevertheless, for this research company can understand their customers better, companies can evaluate their performances based on the customers’ perspective and know their customers’ needs. The company also know their strengths and weaknesses to allocate the resources and maximize their potential. Last but not least, the company is able to know their strategic priority that needs to be done for their better performance in the future to fulfill their customers’ needs and hope to enhance their customer satisfaction

Originality/value
A lot of research about customer satisfaction but still limited especially in the service industry in Indonesia using a combination of IPA and QFD model. So this research will give benefit for SMEs in Indonesia to allocate their resources more effectively by looking at the results of the four quadrants of IPA and house of quality (HOQ) framework can be used for a company as the references for their priority strategic option. Yet, to keep improving, the company recommended reviewing HOQ periodically.
Sustainable and responsible investment funds in Europe
Authors: Sládková Jitka , Kolomazníková Daniela , Formánková Sylvie , Trenz Oldřich , Kolomazník Jan , Faldík Oldřich 
Published: May 2021

Purpose
The sustainable and responsible investing (SRI) is the part of sustainable investment which focusses on mutual funds. The purpose of this paper is to map and evaluate all the active European SRI funds, their performances and correlation with the national identity.

Design/methodology/approach
The sample of the research was analysed with descriptive statistics, mainly the frequency, the mean and the correlation analysis. A well-known volatility is represented by the synthetic risk and reward indicator (SRRI). Other two ratings are the environmental, social and governance (ESG) funds score distribution and the ESG funds letter rating distribution.

Findings
SRI investment may seem to be performing better than in the funds with a different focus. The segment of SRI funds will grow for the next decade.

Research limitations/implications
There is a lack of definitions and clear metrics for sustainable investing. For better performance, it would be also appropriate to examine each country separately.

Practical implications
This paper is part of the project targeting to design a model and methodology of SI evaluation taking into account ESG factors and risks, including profitability in a selected sector. This model can be used by investors for better decision-making.

Social implications
The paper focusses on the funds selecting investments that fulfil ESG criteria, which are part of the social responsibility and sustainability.

Originality/value
An analysis of the current approaches to evaluating investments shows that the key barrier in the transitions to sustainable investment is not taking into account the ESG factors. The research in this paper includes the ESG factors in the evaluation.
Perception and preferences of processed sweet foods: differences between diabetic and nondiabetic consumers
Authors: Soares André Felipe , Honorio Alice Raissa , de Lima Diana Clara Nunes , Tribst Alline Artigiani Lima 
Published: May 2021

Purpose
This paper aims to study how diabetics/pre-diabetics (D) and non-diabetic (regular consumers of sweeteners (C) or not (NC)) perceive and consume sweetened processed food in Brazil.

Design/methodology/approach
A cross-sectional study (n = 2,204) was carried out to gather information about: consumption of 14 sweetened food/beverage categories, perception of sugar/sweeteners (check-all-that-apply (CATA) test), understanding of sugar claims and socioeconomic/demographic/consume profile. Chi-square test/Fisher exact tests were used to analyze the contingency tables. CATA test results were evaluated using Cochran Q test, RV coefficient and Kruskal-Wallis test.

Findings
Results revealed that although diabetics/pre-diabetics consumed less sugary products than non-diabetics (p < 0.001), >50.0% of them preferred sugary candies, bakeries, ready-to-drink fruit juice, ice cream, chocolate and ready-to-eat desserts. D, NC and C similarly perceived (RV = 0.99) sugar (sensory desirable, but penalized due to its health impact), naturally extracted sweeteners (opposite description of sugar) and chemically synthesized sweeteners (penalized by sensory and health impacts). Regarding the claims, those that mean the absence of sugar were correctly understood for = 90.0% participants, while incorrect interpretations were observed for “containing sugars from own ingredients” (42.7%) and “light on sugar” (21.0%), without differences between consumer groups (p = 0.93).

Research limitations/implications
This study was carried out with a convenience sample.

Practical implications
Results can be applied to support food policies and educational campaigns (improving consumer information on processed sweetened foods) and to guide product development in the food industry.

Originality/value
This is the first study to evaluate the Brazilians’ behavior regarding the perception of sugar and sweeteners, the choice of different sweetened processed food, and understanding of sugar claims.

PurposeThe purpose of this study is to evaluate different 3D structures for humidity sensing that will enable the fabrication of complex geometries with high moisture sensitivity.Design/methodology/approachHumidity sensors based on alumina ceramics were fabricated using direct ink write (DIW) technique. Different engineered surface area, polymer binder ratio and post-processing treatment were considered to increase moisture sensitivity.FindingsIt was found that the binder ratio plays an important role in controlling the rheology of the paste during printing and determining the pore size after post-processing treatment. The sensibility of the fabricated humidity sensor was investigated by measuring its capacitance response toward relative humidity (RH) varying from 40% to 90% RH at 25°C. It is shown that using 3D lattice design, printed alumina humidity sensor could improve sensitivity up to 31.6 pF/RH%, over an order of magnitude higher than solid alumina.Originality/valueMost of the alumina humidity sensors available are films in nature because of manufacturing difficulties, which limited its potential of higher sensitivity, and thus broader applications. In this paper, a novel 3D alumina humidity sensor was fabricated using DIW 3D printing technology.
Prevalence and presumptive triggers of localized bullous pemphigoid
Authors: Ständer Sascha , Kasperkiewicz Michael , Thaçi Diamant , Schmidt Enno , Zillikens Detlef , Vorobyev Artem , Ludwig Ralf J. 
Published: May 2021

AbstractBullous pemphigoid (BP) is an autoimmune skin disease, caused by autoantibodies to BP180 and/or BP230. While both these autoantigens are expressed in the entire skin, only some parts of the body become affected. Rare clinical observations indicate that BP may also manifest locally, usually following exposure to triggers. Here, we evaluated the occurrence and potential triggers of localized BP (LBP) in a cohort of 285 BP patients. Medical records of all BP patients hospitalized between 2009 and 2019 were reviewed. In 7/285 BP patients, a localized variant was identified. In 5/7 LBP patients, the disease remained local, while in 2/7 patients, an initial LBP subsequently spread. All cases were preceded by presumptive triggers, including previously described triggers and bacterial infections. Overall, LBP is rare. LBP, however, might be underdiagnosed and should thus be considered in the differential diagnosis, particularly when trigger factors preceded.
Volatile‐mediated interactions with surface‐associated microbes: A parallelism between phyllosphere of plants and eco‐chemosphere of seaweeds
Authors: Saha Mahasweta , Gilon Pauline , Verheggen François 
Published: May 2021

Abstract

Both in terrestrial and aquatic realms, organisms communicate and interact with each other via volatile and non‐volatile infochemicals. Terrestrial plants and seaweeds, known as prolific producers of volatiles, harbour a plethora of microbes on their surfaces like phyllosphere of plant leaves and eco‐chemosphere of seaweeds, respectively, where complex ecological interactions are regulated through infochemicals.

Although plant leaf volatiles have been well‐studied for their ecological functions in mediating microbial interactions, seaweed volatiles have been mostly investigated for their roles in climate regulation and with regard to climate change research. However, seaweed volatiles appear to be related to terrestrial plant volatiles both in terms of chemistry and ecology.

Synthesis. Evidence supports that seaweed volatiles can have important ecological functions in mediating interactions with microbes on their surface, just like plant leaf volatiles. Based on the existing vast literature on ecological interactions mediated by plant volatiles at phyllosphere and on the very few works on ecological roles of seaweed volatiles at eco‐chemosphere, we advocate for the detailed investigation of volatile‐mediated interactions regulating microbial colonisation processes on seaweed surfaces. Although of great ecological importance, this new field of research has remained largely unexplored. Thus, we also set directions for future research programs investigating the roles of seaweed volatiles at seaweed–microbe interface.
“We’re just stuck in a daily routine”: Implications of the temporal dimensions, demands and dispositions of mothering for leisure time physical activity
Authors: Spotswood Fiona , Nobles James , Armstrong Miranda 
Published: May 2021

AbstractThe reduced physical activity of women when they become mothers is a public health priority. Existing studies show that mothers have little time for leisure, or time that is fragmented and requiring negotiation with others. However, the temporal features of mothering are undertheorised and qualitative studies tend to focus on how mothers can skilfully construct physically active identities and balance societal expectations about being a “good mother”. In line with other research that focuses on the configuration of everyday practices that condition the “possibilities” for health‐related practices like physical activity, we shift our focus away from the resisting capacities of mothers to the temporal features of mothering practices. We interrogate the lived experiences of 15 mothers of preschool children in deprived urban areas and illuminate the inherent temporal dimensions, demands and dispositions of mothering practices that condition the possibility of leisure time physical activity being undertaken. Together, these temporal features mean mothering practices can readily work against leisure time physical activity. The focus on the mothering practices rather than mothers brings a novel perspective for developing public health policy designed to support mothers into regular leisure time physical activity.
Up‐scheduling and codeine supply in Australia: analysing the intervention and outliers
Authors: Yu Yan , Wilson Margaret , King Clare E. , Hill Richard 
Published: May 2021

AbstractBackground and aimsOver‐the‐counter codeine products were up‐scheduled to prescription only in Australia from February 2018. This trend study aimed to identify changes in codeine supply before and after the February 2018 implementation.Design, setting and casesTime–series regression analysis of monthly medicine supplies in Australia from 2014 to 2018. The February 2018 up‐scheduling was pre‐specified as the intervention; outlier analysis was used to detect automatically sudden unexpected changes before February 2018.MeasurementsPer‐capita supplies based on national data for pharmaceutical wholesales and population exposure. Weight of supplies in milligrams for low‐dose codeine (≤ 15 mg per tablet or ≤ 1.92 mg per ml, originally sold over the counter but up‐scheduled after February 2018), high‐dose combination codeine (30 mg per tablet, prescription only throughout the study period) and all codeine.FindingsSeveral level shifts in supply occurred during the 5 years, led by one of −4.4% [95% confidence interval (CI) = −6.6 to −2.1%] in high‐dose codeine in 2015, followed by shifts in low‐dose codeine of −40.0% (CI = −46.9 to −32.3%) and −82.2% (CI = −84.3 to −79.9%), respectively, before and after February 2018. High‐dose codeine supply increased by 4.4% (CI = 1.8–7.1%) immediately after up‐scheduling. Also detected were transient increases and decreases in 2016 and 2017. Compared with pre‐2015 levels, the February 2018 up‐scheduling was associated with reductions of 45.7% (CI = 43.2–48.0%) and 89.3% (CI = 87.9–90.6%), respectively, in all and low‐dose codeine supply but no change in high‐dose codeine supply. The level shifts and transient changes were located around various regulatory activities, including public announcements and expert advisory meetings on up‐scheduling.ConclusionUp‐scheduling of over‐the‐counter codeine products in Australia in 2018 appears to have been associated with a near halving of Australia's national codeine supply. The transition occurred in multiple forms and phases.
Economy of Blood: The Persecuted Church and the Racialization of American Copts
Authors: Lukasik Candace 
Published: May 2021

ABSTRACTSince the 1990s, attacks on Egyptian Copts have been made legible to American (particularly evangelical) audiences through the moral imaginary of the “Persecuted Church,” which argues that Christians around the globe are persecuted more than any other time in history. Images of bloodied Egyptian Coptic bodies have circulated among Western Christian religio‐political networks in an “economy of blood,” an imperial economy of Christian kinship that performs the double movement of glory and racialization. This double movement has placed American Copts in a bind, whereby indigenous Coptic collective memory of blood and persecution has intersected with the political, theological, and affective kinship formations of this economy of blood. This article analyzes how the contemporary remapping of Eastern Christian traditions, like that of the Copts, produces effects on a geopolitical scale, and examines how this reconfiguration unfolds whiteness and Western Christianity.

The newly emerging field of pediatric engineering: Innovation for our next generation
Authors: Hirschhorn Matthew , Garven Ellen E. , Wells Jamie L. , Stevens Randy , Tchantchaleishvili Vakhtang , Throckmorton Amy L. 
Published: May 2021

AbstractNeonates, infants, and children have unique physiology and body surface areas that dramatically change during growth and development, and the substantial diversity of complicated pediatric illnesses and rare childhood diseases are distinct from the adult sphere. Unfortunately, medical innovation is generally constrained to retrofitting adult treatment strategies for this heterogeneous population. This conventional, but limited, approach ignores the dynamic biopsychosocial, growth, and developmental complexities that abound, as one progresses through this life cycle from newborn onward toward early adulthood. Forward‐thinking solutions are essential to advance the state‐of‐the‐art to address the challenges and unmet clinical needs that are uniquely presented by the pediatric population, and it has become obvious that newly trained engineers are essential for success. These unmet clinical needs and the necessity of new technical skills and expertise give rise to the emergence of an entirely new field of engineering and applied science: Pediatric Engineering. The field of Pediatric Engineering flips conventional wisdom that adult therapies can simply be scaled or successfully modified for children. It commandeers design to suit the specific needs of the child, while anticipating the dynamic growth and development into adulthood. We are growing a new pipeline of educated scientists and engineers who will have developed a unique toolbox of skills that they can use to tackle unmet clinical needs in global pediatric healthcare for years to come.
Culturally intelligent supervisors: Inclusion, intercultural cooperation, and psychological safety
Authors: Fujimoto Yuka , Presbitero Alfred 
Published: May 2021

AbstractBy integrating the cultural intelligence (CQ) and diversity/inclusion literature, we attempt to make a dual contribution to the literature by understanding how subordinates' perceptions of their supervisors' CQ may enhance their intercultural cooperation via their individual psychological climate for inclusion. We further examine the role of minority members' psychological safety as a result of perceived supervisor CQ and psychological climate for inclusion. To explore these processes, we conducted three studies. Based on social processing and social learning theories, we empirically tested the relationship between perceived supervisor CQ and subordinates' intercultural cooperation and initially determined the role of one of the three dimensions of psychological climate for inclusion (i.e. integration of differences) (Study 1: two‐waves; N = 316). To address the data limitation and to expand the framework (i.e. adding in the other dimensions of psychological climate), we conducted Study 2 (two‐waves; N = 173). We further extended the framework to include psychological safety and obtained two‐waves of data from ethnic minority members in Study 3 (N = 155). Our results supported our predictions offering novel insights into why CQ matters for supervisors of culturally diverse work units and clarify the various mechanisms on how supervisors' CQ influences intercultural cooperation in those units.
