Overconfidence and the adoption of robo-advice: why overconfident investors drive the expansion of automated financial advice
Authors: Piehlmaier Dominik M. 
Published: February 2022

AbstractAdaptive online platforms, powered by artificial intelligence, commonly referred to as robo-advice, steadily increase their market share. Yet these comparably new financial services are critically understudied. Little is known about why some investors adopt robo-advice for something as essential as asset allocation. The current paper tries to close this gap by shedding light on the causal effect of investor overconfidence on the propensity of using robo-advice. The study proposes a theoretical framework that combines the divergence of opinion hypothesis with consumer behavior insights and information technology diffusion research. The framework is empirically tested on the Investor Sample of the 2015 National Financial Capability Study, a subsample of 2000 US investors. The results from a series of generalized linear, structural, and semiparametric models show that in a pre-chasm market, overconfident investors have a significantly higher propensity of adopting robo-advice. While higher financial literacy seems to decrease robo-advice uptake, unjustified confidence in one’s knowledge causally increases it. Willingness to take financial risk cannot account for the significantly increased adoption of robo-advice among overconfident investors. The findings help managers to better position robo-advice by offering behavioral insights into their user base. In addition, the results outline a managerial tool to take demand-side actions to increase the likelihood of an end-user innovation crossing the chasm.

Abstract
Background
For successful implementation of an innovation within a complex adaptive system, we need to understand the ways that implementation processes and their contexts shape each other. To do this, we need to explore the work people do to make sense of an innovation and integrate it into their workflow and the contextual elements that impact implementation. Combining Normalization Process Theory (NPT) with the Consolidated Framework for Implementation Research (CFIR) offers an approach to achieve this. NPT is an implementation process theory that explains how changes in the way people think about and use an innovation occurs, while CFIR is a framework that categorizes and describes contextual determinants across five domains that influence implementation. We demonstrate through a case example from our prior research how we integrated NPT and CFIR to inform the development of the interview guide, coding manual, and analysis of the findings.

Methods
In collaboration with our stakeholders, we selected NPT and CFIR to study the implementation process and co-developed an interview guide to elicit responses that would illuminate concepts from both. We conducted, audio-recorded, and transcribed 28 interviews with various professionals involved with the implementation. Based on independent coding of select transcripts and team discussion comparing, clarifying, and crystallizing codes, we developed a coding manual integrating CFIR and NPT constructs. We applied the integrated codes to all interview transcripts.

Results
Our findings highlight how integrating CFIR domains with NPT mechanisms adds explanatory strength to the analysis of implementation processes, with particular implications for practical strategies to facilitate implementation. Multiple coding across both theoretical frames captured the entanglement of process and context. Integrating NPT and CFIR enriched understandings of how interactions between implementation processes and contextual determinants shaped each other during implementation.

Conclusion
The integration of NPT and CFIR provides guidance to identify and explore complex entangled interactions between agents, processes, and contextual conditions within and beyond organizations to embed innovations into routine practices. Nuanced understandings gained through this approach moves understandings beyond descriptions of determinants to explain how change occurs or not during implementation. Mechanism-based explanations illuminate concrete practical strategies to support implementation.
Barriers and drivers of voluntary blood donation in northern and Western Tanzania
Authors: Finda Florian , Finda Marceline , Olotu Ally 
Published: February 2022

Introduction: Every second, someone in the world needs blood due to surgery, trauma, severe anemia or pregnancy complications. There is a shortage of blood for transfusion worldwide, with the heaviest burden faced by sub–Saharan Africa. In countries like Tanzania, the major source of blood is voluntary blood donation, making its supply one of the most challenging in the health care system. This study assessed the magnitude of the deficit of blood in blood banks, and explored views of key stakeholders on the need, availability and opportunities for improving blood donations in northern and Western Tanzania. Methods: This was an explanatory sequential mixed method study done in the Mpanda and Moshi districts in the Katavi and Kilimanjaro regions. A quantitative component involved a questionnaire survey with 253 community members from the two districts and 24 months blood bank records. The survey explored awareness and perceptions of voluntary blood donation. A qualitative component involved four focus group discussions with registered voluntary blood donors and health care providers from the National Blood Transfusion Service in the two districts. Results: Blood bank records indicated that more blood was collected in Katavi compared to the Kilimanjaro region. Only 26% of the survey respondents had ever donated blood in their lifetime, three quarters of these were from Mpanda district. There was no significant association between socio-demographic factors and likelihood of blood donation. However, being male, older (51 years and above), having higher household income and secondary school education were significantly associated with higher awareness of voluntary blood donation. Community sensitization, education, incentives and availability of blood donation centers near communities were among the most important factors listed to improve blood donation. Conclusions: Significant efforts need to be placed on sensitization and improving knowledge and awareness of voluntary blood donations in order to improve its uptake.
Effect of dietary fat on the activity of palmitic acid elongase in the blood serum and liver of rats
Authors: Velichko V. 
Published: February 2022

Background. To determine the effect of dietary fats on the activity of palmitic acid elongase by two methods, using indicators of the fatty acid composition of lipids in the blood serum and liver of rats.
Methods. Edible vegetable oils were used: high linoleic (HLSO) and high oleic (HOSO) sunflower oils, palm oil (PO). Fats were introduced into the fat-free diet (FFD) in the amount of 5 % instead of the same amount of starch. The animals were fed for 30 days. A fraction of neutral lipids (triglycerides + cholesterol esters) was isolated from blood serum and liver, and the fatty acid composition was determined in it by gas chromatography.
Results. HLSO consumption reduced the biosynthesis of energy fatty acids (C16:0, C16:1, C18:0 and C18:1) in the neutral fraction of serum and liver lipids. A new method for assessing the level of palmitic acid elongase, taking into account the metabolism of palmitic and stearic acids, is proposed, which gives higher values than the commonly used method for assessing elongase. With the help of the new method, elongase activation when HOSO is consumed was determined.
Conclusions. A new method is proposed for the determination of palmitic acid elongase, which takes into account the metabolism of fatty acids. It has been established that the consumption of HLSO reduces the biosynthesis of energy fatty acids. Consumption of HOSO increases elongase activity.
Confronto entre nacionalismos: o caso de Taiwan | Clash between nationalisms: the case of Taiwan

Com o ressurgimento da disputa entre China e Estados Unidos, a questão de Taiwan ganhou nova centralidade na política internacional. O artigo explora o surgimento do nacionalismo taiwanês em contraposição ao chinês. Identifica-se, por trás da disputa política, duas abordagens distintas da identidade nacional. De um lado, o primordialismo que leva à afirmação da identidade chinesa dos habitantes de Taiwan. E, de outro, uma abordagem subjetiva ou instrumentalista que sugere um processo de construção dinâmica de uma nova identidade separada da chinesa. Essa disputa não é entre a República Popular da China e Taiwan, mas entre duas concepções no interior de Taiwan, organizadas politicamente em torno do Kuomintang e do Partido Democrático Progressista. A partir da democratização e do fim do regime autoritário, no final da década de 1980, a identidade taiwanesa ganhou mais adesão, não obstante as intensas relações econômicas, comerciais e o intercâmbio no mesmo período.Palavras-chave: Taiwan; China; Nacionalismos.ABASTRACTThe re-emergence of the rivalry between China and the US, the Taiwan issue gained new centrality in international politics. This article explores the surge of Taiwanese nationalism in opposition to Chinese nationalism. Behind the political tensions one can identify a clash between two different conceptions of national identity. On one side a primordialist conception that reaffirms the Chinese identity of the inhabitants of Taiwan. And on the other a subjective, instrumentalist conception that indicates a process of dynamic construction of a new identity separated from the Chinese one. This clash is not between the Popular Republic of China and Taiwan, but between two conceptions inside Taiwan organized politically around the Kuomintang (pan-blue) and the Democratic Progressive Party (pan-green). Since democratization and the end of the authoritarian regime, Taiwanese identity has grown, notwithstanding the intensification of economic, commercial relations and the exchanges between people over the same period.Keywords: Taiwan; China; Nationalisms.

Para existir música, e não sua representação ou alusão, é preciso que antes exista o sonoro. Partindo desse pressuposto que o compositor francês Pierre Schaeffer, com sua musique concrète, confere importância ao conceito de sonoridade em detrimento ao de musicalidade: ele propõe uma virada de paradigma para a escuta musical, que, ao invés de partir da nota musical (o abstrato), parte do sonoro (o concreto) (FERRAZ, 2004).

Background
Low lung function is associated with high mortality and adverse cardiopulmonary outcomes. Less is known of its association with broader health indices such as self-reported respiratory symptoms, perceived general health, and cognitive and physical performance. The present study seeks to address the association between forced expiratory volume in 1 second (FEV1), an indicator of lung function, with broad markers of general health, relevant to aging trajectory in the general population.

Methods and findings
From the Canadian general population, 22,822 adults (58% females, mean age 58.8 years [standard deviation (SD) 9.6]) were enrolled from the community between June 2012 and April 2015 from 11 Canadian cities and 7 provinces. Mixed effects regression was used to assess the cross-sectional relationship between FEV1 with self-reported respiratory symptoms, perceived poor general health, and cognitive and physical performance. All associations were adjusted for age, sex, body mass index (BMI), education, smoking status, and self-reported comorbidities and expressed as adjusted odds ratios (aORs). Based on the Global Lung Function Initiative (GLI) reference values, 38% (n = 8,626) had normal FEV1 (z-scores >0), 37% (n = 8,514) mild (z-score 0 to > −1 SD), 19% (n = 4,353) moderate (z-score −1 to > −2 SD), and 6% (n = 1,329) severely low FEV1 (z-score = < −2 SD). There was a graded association between lower FEV1 with higher aOR [95% CI] of self-reported moderate to severe respiratory symptoms (mild FEV1 1.09 [0.99 to 1.20] p = 0.08, moderate 1.45 [1.28 to 1.63] p < 0.001, and severe 2.67 [2.21 to 3.23] p < 0.001]), perceived poor health (mild 1.07 [0.9 to 1.27] p = 0.45, moderate 1.48 [1.24 to 1.78] p = <0.001, and severe 1.82 [1.42 to 2.33] p < 0.001]), and impaired cognitive performance (mild 1.03 [0.95 to 1.12] p = 0.41, moderate 1.16 [1.04 to 1.28] p < 0.001, and severe 1.40 [1.19 to 1.64] p < 0.001]). Similar graded association was observed between lower FEV1 with lower physical performance on gait speed, Timed Up and Go (TUG) test, standing balance, and handgrip strength. These associations were consistent across different strata by age, sex, tobacco smoking, obstructive, and nonobstructive impairment on spirometry. A limitation of the current study is the observational nature of these findings and that causality cannot be inferred.

Conclusions
We observed graded associations between lower FEV1 with higher odds of disabling respiratory symptoms, perceived poor general health, and lower cognitive and physical performance. These findings support the broader implications of measured lung function on general health and aging trajectory.

Abstract
The protection of water resource has been the significant mission globally. Hydrochemical compositions and recharge source are the critical tools to analyze the water quality. In this study, 18 surface water and 5 groundwater samples were collected along the Xiongqu and Sequ rivers in the northern Longzi county of southern Tibet. The combination of factor analysis, correlation of major ions, geochemical modeling, and D–O–Sr isotopes were employed to clarify the hydrochemical compositions and recharge source. The concentration of major ions followed the abundance order of

> Cl− for anions and Ca2+ > Mg2+ > Na+ > K+ for cations. Ca–HCO3 and Ca–SO4 types were identified for groundwater and surface water. Based on ratios of major ions and geochemical modeling, it is proposed that the dissolutions of gypsum, calcite, and dolomite controlled the hydrochemical compositions. D–O isotopes indicated a meteoric origin for surface water and groundwater, with the recharge elevation of 2,519–3,731 m. The 87Sr/86Sr ratios of groundwater and surface water were compatible with those of sulfate and carbonate minerals, revealing the main type of minerals interacting with water. The achievements of this study can provide a vital reference for groundwater utilization and protection in the Longzi county and adjacent areas in the Tibet.
Properties of Mexican bloodwood (Haematoxylum campechianum L.). Part 1: anatomical and colourimetric characteristics
Authors: Koddenberg Tim , Brischke Christian , Emmerich Lukas , Kick Annika B. E. 
Published: February 2022

Abstract
Bloodwood (Haematoxylum campechianum L.) native to Central America has been known as dye source since the prehistoric times by the Maya. Nowadays, bloodwood is increasingly used for plantations but its use for furniture, flooring, or fencing is only of regional importance. The reason is seen in lacking knowledge of its properties. To expand that knowledge, this Part 1 of the two-part study series investigated the anatomy and the discolouration due to leaching of heartwood of H. campechianum. Anatomical characteristics were described qualitatively and quantitively using scanning electron microscopy and X-ray micro-computed tomography. Detailed wood anatomical data are presented, together with numerical analyses of cell parameters. Apart from wood anatomy, colourimetric analyses were obtained after 10 leaching cycles. The colour change of the wood due to water exposure was determined measuring in CIE L*a*b* colour system. In addition, the extinction of the leachate was determined spectrophotometrically after each leaching cycle. The resulting colour change was evaluated according to colour change after each cycle. The most prominent change in colour was observed for the first cycle due to leaching. Because of the extensive leaching of extractives, further investigation might address the effect of leaching of water-soluble extractives on adhesion properties of bloodwood.

Abstract
A pair interaction model applying the Bragg–Williams approach is presented. The formalism is given in a general form; ternary ordered compounds with different crystal structures and all possible point defect types are considered. Some applications are discussed. The Bragg –Williams approach is an easily applicable formalism that leads – proper use supposed – to accurate predictions concerning thermodynamic data as well as defect concentrations.
