The Evolution of Sustainability Measurement Research
Authors: Mura Matteo , Longo Mariolina , Micheli Pietro , Bolzani Daniela 
Published: July 2018

AbstractResearch in sustainability measurement has been growing at a very high pace over the past years, and it has explored a variety of issues, from sustainability disclosure to measurement in green supply chains, from the diffusion of environmental standards to the political use of sustainability metrics. This study is the first to report and discuss the results of a comprehensive review of the sustainability measurement literature. In particular, the authors adopt a wide conceptualization of the measurement process, and analyze data through a bibliometric method–bibliographic coupling. The results show that the literature is divided into eight distinct areas of inquiry and 12 sub‐fields, some of which have expanded significantly over recent years, and others appear to be waning. Furthermore, the lack of a comprehensive view of sustainability measurement has led to the development of many separate communities, resulting in duplications of effort, incomplete framing of the problem, and the proposal of partial solutions. However, findings drawn in sustainability measurement research could inform current debates in performance measurement and management in three main ways: by emphasizing stakeholders’ roles in the design, implementation and use of measures; by indicating ways to establish common measures and sharing data between organizations; and by adopting novel theoretical perspectives. Equally, future sustainability measurement studies could benefit from consideration of extant research on strategic performance measurement and on the behavioral effects of measurement practices.
Performance Measurement and Management Systems: A Perspective from Complexity Theory
Authors: Okwir Simon , Nudurupati Sai S. , Ginieis Matías , Angelis Jannis 
Published: July 2018

AbstractComplexity negatively impacts the process of continually improving performance management systems (PMSs). The extant PMS literature considers complexity to be a result of the external environment rather than a user response to that environment. However, this paper argues that organizations generally face internal complexity when adopting PMSs. Introducing PMSs into an organization can have varied effects in those organizations based on the complexity of an organization's associated members and its interactions. This study aims to understand the emergence of complexities while implementing and using PMSs in organizations. From the complexity theory perspective, four system properties (ontological, teleological, genetic and functional) are used to understand complexity in PMSs. The paper builds on a systematic literature review consisting of 76 papers and analyses them in the light of exploring sources of complexity when implementing and using PMSs. From the outset, complexity is understood to be a result of the conflict between existing organizational practices and mechanisms and the organizational controls associated with PMSs. The key findings abstracted six sources of complexity in this study: role, task and procedural types of complexity associated with the social dimension, and methodological, analytical and technological types of complexity associated with the technical dimension. The study findings contribute to the current discussion regarding why PMSs typically lag and are not responsive and resilient in emerging contexts. While understanding and exploring all organizational controls that moderate a PMS is useful, organizations should construct the necessary capabilities, depending on their context and adapt to the changes associated with PMSs.

AbstractBackgroundThe comparative effectiveness of biologic treatment regimens in a real world Australian population is unknown.AimTo assess the effectiveness of biological disease‐modifying anti‐rheumatic drugs (bDMARD) as monotherapy or in combination with methotrexate and/or other conventional DMARD (cDMARD) for the treatment of rheumatoid arthritis (RA).MethodsA retrospective, non‐interventional study was conducted that investigated the use of bDMARD in adult patients with RA in routine clinical practice. Data were extracted from the Optimising Patient Outcomes in Australian Rheumatology – Quality Use of Medicines Initiative database. Real‐world effectiveness was measured using the 28‐joint disease activity score (DAS28) and clinical disease activity index (CDAI) by treatment group at baseline, weeks 12 and 24.ResultsA total of 2970 patients was included with a median (min–max) age of 60.0 (19.0–94.0) years and median (min–max) duration of RA before first bDMARD treatment of 6.0 (0.2–58.3) years. A total of 1177 patients received more than one bDMARD during the analysis period of 1 January 1997 to 15 August 2015. Patients had 4922 treatment ‘episodes’ (defined as a cycle of continuous individual bDMARD prescribing in a single patient). Patients received a mean (SD) of 1.7 (1.0) episodes of treatment with median (min–max) treatment duration of 0.7 (0–11.8) years; median treatment duration was higher with the first treatment episode. bDMARD were most commonly initiated in combination with methotrexate (73.9% of episodes) and least commonly as monotherapy (9.9% of episodes). Median (min–max) baseline DAS28 decreased from 5.3 (0–8.7) with the first bDMARD to 3.7 (0–8.8) with the second. Median baseline CDAI similarly decreased.ConclusionsPatients tended to persist longer on their first bDMARD treatment. bDMARD as monotherapy or in combination appear to be accepted treatment strategies in the real world.

Published: July 2018

AbstractElectronic structures and magnetic properties of Li and Mn codoped LiZnN systems were investigated by using the first‐principles calculations. Mn‐doped LiZnN systems preferred the antiferromagnetic states, while Mn/Li codoped LiZnN systems were ferromagnetic and more stable than the Mn‐doped LiZnN systems. The magnetic moments mostly arose from Mn‐3d states, which hybridized with N‐2p and Li‐2s states near the Fermi level. The ferromagnetic coupling was suggested to be attributed to the p‐d hybridization by the Mn–N–Mn chain. The results indicated that nonstoichiometry of Li was very essential for the ferromagnetism of Li(Zn,Mn)N system.
Sexual Harassment and Assault in Domestic Work: An Exploration of Domestic Workers and Union Organizers in Brazil
Authors: Ribeiro Corossacz Valeria 
Published: July 2018

ResumenOs estudos sobre trabalho doméstico demostram que os assédios sexuais contra as trabalhadoras domésticas por parte dos empregadores representam um problema difundido em todo o mundo. No Brasil, é uma questão amplamente conhecida, cujas características remetem ao passado de escravidão. Nesse artigo apresento os dados de uma pesquisa entre trabalhadoras domésticas e sindicalistas que foram entrevistadas com o objetivo de examinar esse fenômeno, colocando‐o em relação às condições de trabalho, ao racismo e sexismo presentes na sociedade brasileira. Examino de forma detalhada as reações das mulheres aos assédios sexuais e à questão do silêncio que envolve essa forma de violência, sugerindo que o silêncio das trabalhadoras sobre as experiências de assédio no emprego deve ser interpretado como uma forma de reação e resiliência, relacionadas a uma situação mais ampla de opressão social.

Did the Founding of the Federal Reserve Affect the Vulnerability of the Interbank System to Contagion Risk?
Authors: CARLSON MARK , WHEELOCK DAVID C. 
Published: July 2018

AbstractThe Federal Reserve System was established to supplant the private interbank system, which was widely seen as a source of instability. We examine how the Fed's presence affected the interbank system's resilience to solvency and liquidity shocks and whether those shocks might have been contagious. The interbank system became more resilient to solvency shocks but less resilient to liquidity shocks as banks sharply reduced their liquid assets after the Fed's founding. The industry's response illustrates how the introduction of a lender of last resort can alter private behavior in ways that increase the likelihood that the lender will be needed.
Using Market Expectations to Test for Speculative Bubbles in the Crude Oil Market

Published: July 2018

AbstractThe wide fluctuations of oil prices from 2003 to 2008 have attracted the interest of academics and policymakers. A popular view is that these fluctuations were caused by speculative bubbles due to the increased financialization of oil futures markets. This hypothesis, however, is difficult to examine since the fundamental price of oil is unobservable and, therefore, econometric evidence in favor of bubbles may actually be due to misspecified market fundamentals. In this paper, we extend two recently proposed methodologies for bubble detection that alleviate this problem by using market expectations of future prices. Both methodologies provide no evidence of speculative bubbles.
The embodied experience of pregnancy with an ileostomy
Authors: Whiteley Ian , Gullick Janice 
Published: July 2018

Aims and objectivesTo understand women's experience of pregnancy with an ileostomy following bowel resection for inflammatory bowel disease or familial adenomatous polyposis.BackgroundWhile symptoms of IBD/FAP can be debilitating and life‐threatening, ostomy formation can effectively manage symptoms. Research on pregnant women with an ostomy is sparse. While some literature suggests pregnant women with an ostomy can have a normal pregnancy and birth, documented stoma complications include intestinal obstruction, peristomal hernia, retraction, stenosis, laceration, bleeding, prolapse, pouching problems, nausea, vomiting and dehydration.DesignHermeneutic phenomenology.MethodsAll known women (n = 8) who had been pregnant with an ileostomy were recruited from the stomal therapy departments of two teaching hospitals. Single in‐depth interviews were digitally recorded and transcribed verbatim. Hermeneutic phenomenological analysis was guided by the philosophy of Merleau‐Ponty. Reporting rigour was guided by the consolidated criteria for reporting qualitative research.ResultsThere was a lower level of concern among pregnant woman with an ostomy than anticipated. Women described the following: the “hell” of the disease; the stoma as a lifeline; heading into uncharted waters; wanting to be normal; the shared space of the baby and the diseased abdomen; pregnancy as a dark tunnel; and the unreliable body.ConclusionWomen with inflammatory bowel disease frequently experience debilitating symptoms and serious ill health. Ileostomy formation improves symptoms and the sense of “feeling normal,” facilitating readiness for conception, pregnancy and motherhood. However, women's uncertainty about conception and pregnancy persists due to the scarce information and experiences offered by clinicians, and fears around their unreliable body during pregnancy. Given this uncertainty for both women and their treating clinicians, outcomes should be documented and shared to reassure women of child‐bearing age that pregnancy and birth can be safe with a stoma.Relevance to practiceWomen and clinicians should aim for disease remission, peer support, ongoing monitoring and involvement of a Stomal Therapy Nurse.

AbstractPurposeTo evaluate the accuracy (trueness and precision) of dental replica models produced by using photopolymer materials in additive manufacturing.Materials and MethodsA complete arch model was scanned using an extraoral scanner (Identica Blue) and established as reference. For the control group, 10 stone models were acquired through the conventional method from the reference model. For the experimental groups, digital data were acquired using an intraoral scanner (CEREC Omnicam), and 10 stereolithographic apparatus (SLA) models and 10 PolyJet models were made. All models were scanned with an extraoral scanner. Three‐dimensional analysis software was used to measure differences between the 3D scanned images in root mean square values. The ISO‐5725‐1 specification was followed to measure trueness and precision between two 3D scanned data. Trueness was calculated by overlapping scanned data with the reference model and precision by performing pairwise intragroup comparisons. Also the ratio of region out of tolerance (> ±50 μm) was measured. One‐way ANOVA and Tukey's post hoc analysis were applied.ResultsThere was no statistically significant difference in trueness between the stone and the SLA models (p > 0.05). Dental replica models using photopolymer materials showed statistically significantly better precision than that of the stone model (p < 0.05). Regarding tolerance, no statistically significant difference was observed between the stone and the SLA models (p > 0.05).ConclusionsAlthough the dental replica models using photopolymer materials did not show better trueness than the conventional stone models, there was no significant difference between the SLA and the stone models. Concerning precision, dental replica models using photopolymer materials presented better results than that of the conventional stone models. In sum, dental replica models using photopolymer materials showed sufficient accuracy for clinical use.

Authors: Alayad Abdullah Saeed 
Published: July 2018

AbstractPurposeTo evaluate the influence of various Y‐TZP thicknesses and veneer firing cycles on the strength of two ceramic veneers.Materials and Methods180 Y‐TZP cores of 0.5, 1.0, and 5.0 mm thickness were prepared followed by sintering in a high temperature furnace; 180 presintered veneering ceramic discs (Vita VM9 porcelain and e.max Ceram) were also prepared using a mold. The discs were placed on zirconia plates (zirconia cores) of different thickness (0.5, 1.0, and 5.0 mm) and exposed to different firing cycles (Vita VM9 porcelain‐910, 930, and 950°C; e.max Ceram‐750, 770, and 790°C). Ball‐on‐three‐balls flexural strength test was performed (universal testing machine) at a crosshead speed of 0.5 mm/min. Scanning electron microscopy of fractured specimens was performed. Means and standard deviations of flexural strength were analyzed using Tukey‐Kramer HSD test for multiple comparisons.ResultsSpecimens within material groups showed no significant difference (p > 0.05) for flexural strength with respect to Y‐TZP core thickness (0.5, 1.0, and 5.0 mm) (VM9 [117.30 ± 14.328, 117.75 ± 13.66, 113.75 ± 20.10], e.max Ceram [94.79 ± 17.5, 100.02 ± 14.7, 95.23 ± 15.4]). Flexural strength within material groups with respect to different firing cycles ([VM9‐910, 930, 950°C], e.max Ceram [750, 770, 790°C]), for VM9 (111.49 ± 15.7, 120.86 ± 13.2, 116.46 ± 18.4), and e.max Ceram (94.64 ± 15.2, 101.6 ± 16.69, 93.8 ± 15.20) showed no significant difference (p > 0.05).ConclusionsDifferent zirconia thicknesses (0.5, 1.0, and 5.0 mm) and veneer firing cycles for Vita VM9 and e.max ceramics failed to show any significant influence on their biaxial flexural strengths.
Comparative Ambiguity Aversion in Intertemporal Decisions
Authors: Wang Jianli , Li Jingyuan 
Published: July 2018

AbstractThis article examines the effects of ambiguity aversion on intertemporal decisions when there is ambiguity about a future state. Compared to the existing literature, we allow for a three‐way separation between intertemporal substitution, risk aversion, and ambiguity aversion. Holding risk preferences, beliefs, and time preferences fixed, we explore how a change in ambiguity aversion increases the strength of the current willingness to pay. We apply our results to saving, self‐protection, and self‐insurance problems.

Published: July 2018

SummaryChronic hepatitis B virus (HBV) infection is a prevalent public health issue worldwide. Its impact on important pregnancy outcomes, such as gestational diabetes mellitus (GDM), has not been clearly established. The findings from published studies are inconsistent. In this systematic review and meta‐analysis, we aimed to clarify whether HBV infection manifested during pregnancy is associated with an increased risk of GDM. We searched MEDLINE and EMBASE for cohort studies and case‐control studies that investigated the association between maternal hepatitis B surface antigen (HBsAg) positivity and GDM. We pooled adjusted odds ratio (aOR) and unadjusted OR, respectively, using the random‐effect generic inverse variance method. We assessed risk of bias using the Quality in Prognosis Studies tool and conducted five pre‐specified subgroup analyses. In total, 23 cohort studies involving 3 529 223 participants were included. The risk of GDM was 6.48% (1868/28 829) among HBsAg‐positive pregnant women and 3.41% (119 283/3 500 394) among HBsAg‐negative pregnant women. Meta‐analyses of both unadjusted and adjusted effect estimates showed that HBsAg positivity during pregnancy was associated with higher risk of developing GDM (unadjusted OR 1.35, 95% CI: 1.17 to 1.56, I2 = 82.6%; adjusted OR 1.47, 1.22 to 1.76, I2 = 62%). Among pre‐specified subgroup analysis, significant differences were found among studies with high vs low or moderate risk of bias. The results were robust to sensitivity analyses. In conclusion, HBsAg positivity during pregnancy has a moderate effect on an increased risk of GDM. Given the size of the population with HBV infection worldwide, however, this effect could have substantial impact on pregnancy. Further studies are warranted to investigate whether active infection with HBeAg positivity would further elevate the risk of adverse events during pregnancy.

AbstractSmallholder farmers dependent on rain‐fed agriculture experience seasonal variations in food and nutrient availability occasioned by seasonality of production patterns. This results in periods of nutrient abundance in the plenty seasons followed closely by periods of nutrient inadequacies and malnutrition. This pattern contributes to a cycle of deteriorating health and nutrition status and deprives children of their ability to realize full developmental potential. This study investigates the role of caregiver's nutritional knowledge and attitudes in mediating effects of seasonality on children's diets. Repeated cross‐sectional surveys were conducted on 151 randomly selected households in the plenty and lean seasons to collect dietary data using two non‐consecutive quantitative 24‐hr recalls and caregiver's nutritional knowledge and attitudes assessed using interviewer administered questionnaire. Sixty‐five percent of the caregivers had attained a primary level education or less. There was a positive modest correlation between caregivers' nutritional knowledge and their attitudes (r = 0.3, P < 0.000, α = 0.01). Children's mean adequacy ratio was significantly higher in the plenty season than in the lean season (0.84 vs. 0.80, P < 0.000). A two‐block hierarchical regression to predict the seasonal changes in dietary quality of children using caregiver's nutritional knowledge and attitude scores while controlling for the effect of sociodemographics and mean adequacy ratio at first season (plenty) found that caregiver's nutritional knowledge (ß = −0.007, SE = 0.003, P = 0.027, 95% CI [−0.013, −0.001] ŋ2 = 0.034) but not attitudes had significant contribution to the prediction. Maternal nutritional knowledge mediates seasonal variation in child nutrient intakes.

AbstractThe Brazilian state of Goiás, untouched by spotted fever (SF) until 2012, has subsequently reported cases of the disease in several regions. This study aimed to survey the diversity of potential vectors and rickettsia in areas of Goiás under environmental surveillance or case investigation for SF. Collected specimens were assayed with molecular biology technology using DNA extraction, amplification and sequencing of fragments of the genes gltA, ompA, ompB and sca4 to detect rickettsia in ticks and fleas. Amplification of cytochrome oxidase subunit II and 16S rRNA was performed to assist tick identification. Rickettsia felis (Rickettsiales: Rickettsiaceae) was found in Ctenocephalides felis (Bouché, 1835) (Siphonaptera: Pulicidae). Rickettsia bellii was found in Amblyomma rotundatum Koch, 1844 (Ixodida: Ixodidae) and in Amblyomma cajennense sensu lato. Rickettsia sp. strain NOD was found in Amblyomma nodosum Neumann, 1899. Of the Amblyomma cajennense complex, Amblyomma sculptum Berlese, 1888 was confirmed in the northern, northeast, midwest and southeast regions of Goiás, whereas Amblyomma cajennense sensu stricto (Fabricius, 1787) was found only in the northern region of the state. Amblyomma dubitatum Neumann, 1899 associated with a species of the A. cajennense complex was the most common epidemiological finding, although Rickettsia rickettsii was not detected. This is the first report of Rickettsia sp. strain NOD in Goiás.
