Background
Dogs are considered the major domestic reservoir for the human visceral leishmaniasis, a serious disease caused by the Leishmania infantum parasite. Diagnosis of the canine visceral leishmaniasis (CVL) is critical for disease control, with several methods currently available. Among the serological tests, the DPP rapid test and the EIE-LVC, more commonly used in Brazil, are associated with variable sensitivity and specificity. Research with novel recombinant proteins may therefore improve on the CVL diagnosis, such as the ELISA with the recombinant chimeric protein Q5. This study aimed to compare the Q5 in ELISA with the EIE-LVC (Leishmania major) using a large number ofCVL suspected sera (406) with a previous diagnosis based on the rapid DPP test.
Methods
Serum samples from dogs CVL positive in the rapid DPP test (n=406) and negative samples from healthy dogs (n=46) were used for ELISA tests using recombinant proteins Q5 and Lci13. The data obtained in the ELISA as well as the correlation with the clinical signs and the Socio-environmental characteristics of the animals were calculated using MedCalc and GraphPad Prism 8.0.
Results
Overall, similar levels of a lower sensitivity (67-68%) were seen for both the commercial EIE-LVC test and the Q5 ELISA when all assessed sera were considered, but a much greater sensitivity (92%) was seen for those from symptomatic dogs only. In contrast, a large number of negative results were observed for the DPP-positive sera from asymptomatic dogs or those with no clinical information available. A selection of those were tested yet again in new ELISA assays using a second batch of the Q5, purified under milder denaturing conditions, as well as another recombinant protein (Lci13).
Conclusions
The results reveal a higher-than-expected incidence of false-positive results for DPP, reinforcing the need for other recombinant proteins, such as the chimeric Q5, to be investigated as possible alternatives to the currently used CVL diagnostic methods.
Psychometric Properties of an Arabic Translation of the 10-item Connor-Davidson Resilience scale (CD-RISC-10), the 8- and 10-item Post-Traumatic Growth Inventory-Short Form (PTGI-SF) scales

Published: March 2023

Background: Given their clinical significance and impact on stress response and their potential malleability, resilience and posttraumatic growth (PTG) should receive greater attention as relevant constructs in clinical and research practice in the Arab context. We aimed through the present study to test the psychometric properties of Arabic translations of the 10-item Connor-Davidson Resilience scale (CD-RISC-10), the 10-item and the 8-item Post-Traumatic Growth Inventory-Short Form (PTGI-SF) in a sample of Lebanese adults from the general population.
Methods: Three hundred eighty-seven Arabic-speaking participants (mean age = 26.17; 58.4% females) responded to a self-report web-based questionnaire.The forward and backward translation method was appliedwith the approval of the original developers of the scales.
Results: Confirmatory factor analysis indicated that fit of the one-factor model was acceptable, and all indices suggested that configural, metric, and scalar invariance was supported across gender for all the three scales. The CD-RISC-10, the 10-item and the 8-item PTGI-SF yielded a good internal consistency, with a McDonald’sω of .89, .95, and .93, respectively. Higher resilience and higher PTG were significantly and positively associated with greater cognitive reappraisal and lower emotion suppression, supporting convergent validity.
Conclusion: We preliminarily suggest that these Arabic instruments are appropriate for use in Lebanese community adults to assess different positive responses after life crises, identify people with lack or low levels of resilience and growth who might need intervention, and monitor their response to therapy. Further cross-cultural validations should seek to extend their use in broader Arabic-speaking populations and settings.

Published: March 2023

Background: In Puerto Rico (PR), the burden of risk factors for cardiovascular disease (CVDRF) in women is high. CVDRF during pregnancy is a threat to maternal and child health. Little is known about CVDRF among pregnant women in PR.
Methods: Cross-sectional study using data from pregnancy charts (n=264; no prior pregnancies) from an outpatient clinic in PR. CVDRF included: pre-pregnancy obesity, type 2 diabetes (T2D), and hypertension, and gestational diabetes and hypertension. Age was categorized as: 21-25y, 26- 30y, and 31-35y. Analyses included adjusted logistic and multinomial regressions.
Results: Obesity pre-pregnancy was the most common CVDRF (23.5%). Women of 31-35y (vs. 21-25y) had higher odds of T2D/gestational diabetes (OR=4.66; 95% CI=1.18, 18.4) and were more likely to experience 2+ CVDRF (RRR=2.73; 95% CI=1.10, 6.80).
Discussion: Pregnant women in PR experienced CVDRF, and these were more common among women of older age. Studies are needed to confirm our findings and monitor the health of women at high risk of CVD during postpartum.
Significance: There is a need for studies documenting CVD risk factors among pregnant women in PR. Such knowledge is needed for early intervention and to preserve women’s health and that of children in PR.
Self-objectification during the perinatal period: The role of body surveillance in maternal and infant wellbeing
Authors: Laifer Lauren M. , Maras Olivia R. , Sáez Gemma , Gervais Sarah J. , Brock Rebecca L.
Published: March 2023

Pregnancy represents a unique time during which women’s bodies undergo significant physical changes (e.g., expanding belly, larger breasts, weight gain) that can elicit increased objectification. Experiences of objectification set the stage for women to view themselves as sexual objects (i.e., self-objectification) and is associated with adverse mental health outcomes. Although women may experience heightened self-objectification and behavioral consequences (such as body surveillance) due to the objectification of pregnant bodies in Western cultures, there are remarkably few studies examining objectification theory among women during the perinatal period. The present study investigated the impact of body surveillance, a consequence of self-objectification, on maternal mental health, mother-infant bonding, and infant socioemotional outcomes in a sample of 159 women navigating pregnancy and postpartum. Utilizing a serial mediation model, we found that mothers who endorsed higher levels of body surveillance during pregnancy reported more depressive symptoms and body dissatisfaction, which were associated with greater impairments in mother-infant bonding following childbirth and more infant socioemotional dysfunction at 1-year postpartum. Maternal prenatal depressive symptoms emerged as a unique mechanism through which body surveillance predicted bonding impairments and subsequent infant outcomes. Results highlight the critical need for early intervention efforts that not only target general depression, but also promote body functionality and acceptance over the Western “thin ideal” of attractiveness among expecting mothers.
Ukrainian Community Archives in Victoria, Australia: A Stocktake

Published: March 2023

Contemporary research increasingly recognizes the role of community archives in preserving evidence of the pasts of identity groups, validating their historical experience, and thus furthering the goals of social justice and equality. Such values underlie the Association of Ukrainians in Victoria (Australia) Archival Project, which the present article places into the broader context of Ukrainian community archival collections in the state of Victoria. Data obtained through interview have enabled a descriptive survey of such collections, which are found to be concentrated in a handful of “archival clusters” in suburban Melbourne and regional Victoria. The most typical contents of the collections—records of the proceedings and activities of community secular and religious organizations—reflect the dominant role in the community’s life of organizations established by post-World War II immigrants. The collections constitute a rich resource for research into the part of the community encompassed by these organizations, even if, as a rule, at least at present, they are not well ordered or described. They are less revealing of the experience of immigrants who arrived later or were less inclined to join community organizations. Lack of resources, both human and material, confronts the mainly volunteer officeholders who are responsible for the organizations’ archives. In consequence, collections are often inadequately and sometimes unsafely housed, and in general only informally organized; finding aids or descriptions of them are seldom available. Initiatives taken by some organizations suggest that there is growing awareness among community activists of the potential value of archives for showing and interpreting the community to itself and to others.
Resisting Russification in Soviet Ukraine through Literary Translation: The Voice of Mykola Lukash
Authors: Savchyn Valentyna
Published: March 2023

The Soviet totalitarian regime not only violated human rights, it pursued an aggressive policy of assimilation, seeking Russian cultural and linguistic hegemony over all Soviet republics. Literary translation was no longer viewed as an apolitical activity and became an ideological weapon and an efficient “means of forced cultural change” (Monticelli). Regime ideologues sought control over both the selection of “reliable” authors / texts for translation and the ways in which these texts were interpreted in the target languages. This policy led to the appearance of massive translations from Russian literature and a widespread practice of indirect translations, with Russian intermediary texts as a criterion of fidelity. In Soviet Ukraine, however, this Russification policy went further and targeted the Ukrainian language itself; this resulted in the lexicographical deactivation of many authentic Ukrainian words and their substitution with Russian counterparts. Extensive repressive practices and tight ideological constraints gave rise to translators’ activism and cultural resistance and inspired translators to take on new roles. The case of Mykola Lukash (1919–88), whose name went down in the history of Ukrainian translation as a symbol of resistance, illustrates some of the social roles performed by translators to resist Russification. Lukash’s actions as translation gatekeeper, cultural custodian, and language guardian exemplified the importance of personal agency and a firm occupational identity for translators who opposed assimilation.
Liturgical Translation in Europe’s Medieval East: Matters of Civilization and Textual Praxis
Authors: Shmiher Taras
Published: March 2023

The paper focuses on the medieval period of the history of liturgical translation in Ukraine and Poland. In the ninth century, the evangelizing mission of SS Cyril and Methodius brought Christian translations to the east of what was then Europe. Although religious translations were not cherished in Moravia and Poland, they flourished in Bulgaria, Serbia, and Ukraine. The Roman corpus of liturgical texts existed only in Latin, and socio-political conditions stimulated the emergence of translations from Latin to Polish. The Byzantine corpus was introduced in Old Church Slavonic, which was understood by and accepted among Slavs. Different nations modified these texts according to their local visions and the necessities of their churches. Poland’s and Ukraine’s liturgical praxis under the aegis of the Roman and Byzantine Mother-Churches defined the shaping of different corpora of liturgical books, but the quality of translations was high in all Slavonic translations. The (typically) negatively judged strategy of literalism prepared a foundation for lingual experimentation in semantic expression and helped to spread the local melodies of liturgical tradition. The Church Slavonic language gave a more fruitful impetus to the development of early Ukrainian literature than the Latin language provided to early Polish literature. In fact, the Latin language restrained a similar development of early Polish literature for two centuries.

Published: March 2023

In the context of misinformation and inaccuracies in reporting, the knowledge and understanding of news production processes and conditions are crucial for news users’ perceptions of news content. However, research on the users’ perception of errors in news and the influence of corrections and individual factors is scarce. In two online experiments, we investigated the influence of corrections, newspaper type, and news media literacy on users’ perceptions of error severity and frequency. Corrections decreased the perceived severity of errors in both studies. News media literacy increased the perceived severity of errors in political news (Study 1) but not in sports news (Study 2). Further, news-literate users perceived errors in political news as more frequent. Newspaper type did not influence user perceptions. These results support the need for transparency and the importance of user characteristics – especially news media literacy – when studying perceptions of journalistic products.
Improving the Prediction Accuracy in Deep Learning-based Cryptocurrency Price Prediction
Authors: BALCI Furkan
Published: March 2023

Cryptocurrencies are popular today even though they do not have a physical form with their high profit rates and increasing usage day by day. However, the volatility of cryptocurrencies is higher than physical currencies. These volatilities change with the effect of social media rather than changes in exchange rates of physical currencies. For this reason, in this study, using Twitter data, one of the most widely used social media tools, real-time analysis on the values of four cryptocurrencies with the highest market value and the change in the estimated success compared to classical approaches were examined. The basic steps of this study: Obtaining Twitter data and financial data, performing sentiment analysis using Twitter data, making predictions on MM-LSTM architecture. The approach is aimed to be a predictive method open to online learning. Various filter steps were applied to remove the effect of bot users on Twitter that could prevent the prediction performance on the created data set, and the effect of the method on accuracy rate was tried to be reduced by eliminating the activity of bot accounts.

Heart rate is an important indicator of health and disease and the modulation of heart rate can help to improve cardiovascular outcomes. Besides β-blockers, Ivabradine is a well-established modulating drug that reduces heart rate without any hemodynamic effects. This consensus document was developed with the help of expert opinions from cardiologists across India on effective heart rate management in routine clinical practice and choosing an appropriate Ivabradine-based therapy considering the available scientific data and guideline recommendations. Based on the discussion during the meetings, increased heart rate was recognized as a significant predictor of adverse cardiovascular outcomes among patients with chronic coronary syndromes and heart failure with reduced ejection fraction making heart rate modulation important in these subsets. Ivabradine is indicated in the management of chronic coronary syndromes and heart failure with reduced ejection fraction for patients in whom heart rate targets cannot be achieved despite guideline-directed β-blocker dosing or having contraindication/intolerance to β-blockers. A prolonged release once-daily dosage of Ivabradine can be considered in patients already stabilized on Ivabradine twice-daily. Ivabradine/β-blocker fixed-dose combination can also be considered to reduce pill burden. Two consensus algorithms have been developed to further guidance on the appropriate usage of Ivabradine-based therapies. Ivabradine and β-blockers can provide more pronounced clinical improvement in most chronic coronary syndromes and heart failure with reduced ejection fraction patients with a fixed-dose combination providing an opportunity to improve adherence.
Sauchinone Inhibits the Proliferation and Immune Invasion Capacity of Colorectal
Cancer Cells through the Suppression of PD-L1 and MMP2/MM9
Authors: Lu Yiping , Yu Miao , Ye Jinsheng , Liang Yankai , Gao Jianxin , Ji Zhen , Wang Jie
Published: March 2023

Background:

Colorectal cancer (CRC) is one of the most common tumors globally and a leading cause of
cancer-related death. In China, CRC is the third most common cancer type. Sauchinone is known to exhibit anti-tumor
and anti-inflammatory activity, but its effects on CRC have not been investigated to-date

Objective:

To investigate the effects of Sauchinone on CRC development and metastasis and its underlying mechanism(
s) of action.

Methods:

SW480 and HCT116 cells were treated with a range of concentrations of Sauchinone. Cell proliferation was
measured using EDU assays and flow cytometry.

Results:

Treatment with 50 μM Sauchinone decreased the expression of MMP2 and MMP9 and downregulated PD-L1
expression (PD-1/PD-L1) leading to checkpoint inhibition. Sauchinone treatment also enhanced the cytotoxicity of
SW840 and HCT116 cells co-cultured with CD8+ T cells. The overexpression of PD-L1 rescued the anti-proliferative
and cytotoxic effects of Sauchinone in both types.

Conclusions:

We show that Sauchinone suppresses CRC cell growth through the downregulation of MMP2 and MM9
expression and PD-1/PD-L1 mediated checkpoint inhibition. Collectively, these data highlight the promise of Sauchinone
as a future anti-CRC therapeutic.

Covid-19 pandemic causes all face-to-face activities converted to distance or virtual meetings, including educational learning system. These days, the majority educational institutions in Indonesia still implement distance learning via video conference platforms. This primary research aims to discover how Zoom Fatigue affects health and causes learning loss in university students across Java. The methodologies used in this research are qualitative and quantitative. To specify this research, the population is set to students who study at several universities in Java, with 50 samples being Multimedia Nusantara University students and the other 50 sample are being students from other universities in Java. The techniques used to collect data are observation and questionnaire via Google Forms. After analyzing responses, the result shows that most students experience health issues such as eyesight issues, exhaustion, and saturation. Moreover, most students also go through some issues when it comes to the learning process, they experience a decrease of learning motivation and have trouble concentrating. Nevertheless, their academic records are stable and some even stated that their grades are increasing when compared to face-to-face learning systems, this fact shows that in-class learning is not the only source of information used by students to support their academic performance, but there are other sources of information such as internet where students can look up information from online article and scientific journals.

The propagation of a localized ring nonlinear wave in carbon nanotubes (CNTs) of armchair type has been explored using the MD/DFTB method. It is unambiguously shown that the considered localized waves are soliton-type. Herewith, the higher a velocity of an initial perturbation, the higher a steady-state velocity of the considered soliton. It is established that at a high initial excitation energy in a time period of 0.1-0.2 ps the soliton moves at the speed in the range of 245-270 Å/ps, which is approximately in 1.22-1.35 times higher than the speed of sound in CNTs (200 Å/ps). It is shown that the soliton velocity practically does not change with increasing CNT radius

In this paper, we present the results of processing metallic gallium in an ammonia vapor medium at 2 bar pressure by femtosecond laser pulses. The influence of the ammonia concentration and the mode of laser beam scanning on the result of laser action is considered. It has been established that an increase in the concentration of ammonia vapor and a change in the scanning regime lead to a radical change in the laser ablation process. A decrease in the scanning speed leads to the cessation of the ablation process and the development of the nitridation process of the gallium surface, accompanied by the formation of columnar structures up to 12 mm long and about 100 μm in diameter. The synthesized nanoparticles and structures were studied using scanning electron microscopy, Raman spectroscopy, and X-ray analysis.

The paper considers the problem of optimizing gas-discharge sources of multiband UV radiation – excilamps. A method is proposed for estimating the ratio of partial pressures of the components of a gas mixture, which makes it possible to simplify the process of developing a multiband excilamp with the desired power ratio of the emission bands. It is shown that the optimization of a multiband excilamp on a mixture of one noble gas with several halogen carriers can be reduced to the problem of optimizing an excilamp on a two-component mixture. If, in addition to the radiation of exciplex molecules, the radiation of excimer molecules is of importance, then the method makes it possible to control the relative contribution of the powers emitted by these molecules.
Влияние частичного замещения железа на элементы IV группы на структуру и сверхпроводящие свойства соединения Fe(Se-=SUB=-0.2-=/SUB=-Te-=SUB=-0.8-=/SUB=-)-=SUB=-0.82-=/SUB=-

The structure and superconducting properties of the Fe1 – x(A)x(Se0.2Te0.8)0.82 (x = 0.1, 0.2) compound, where A is Cu, Zn, Bi or Group IV elements (Pb, Sn, Ge), were studied. It was shown that the effect of substitution of some iron atoms on the structure and superconducting properties of the Fe(Se,Te) compound depends on whether a solid solution with a substituting element was formed. If complete dissolution of the replacement element occured (Cu, Zn), then a significant degradation of the superconducting properties was observed. If a separate chalcogenide phase was formed (substitution by Pb, Sn, Ge), then a slight change in the superconducting properties was observed. Such a slight change and even improvement in the superconducting properties upon precipitation of the chalcogenide phase can be associated with both the positive effect of an increase in the relative content of iron and a decrease in the number of iron atoms in the interstitial sites of the β phase. The preservation of the superconducting properties of the Fe(Se,Te) compound with a small substitution of iron for group IV elements can be used to create wires based on Fe(Se,Te), since impurity chalcogenide particles can act as effective pinning centers.

The structure and strength of Al−xSi−2wt.%Cu (x = 15, 17 and 20wt.%) alloys obtained by directional solidification at a rate of 0.1 and 0.8mm/s are investigated. It is shown that the tensile strength increases with an increase in the rate of solidification due to a decrease in the size of eutectic silicon and the transformation of its crystal flake into a fine-fiber one. In addition, there was an increase in tensile strength due to an increase of the share of the intermetallic phase, exceeding the reduced tensile strength due to an increase in the amount of the α-Al phase. An increase in the silicon content in the samples during solidification at a rate of 0.1 mm/s does not lead to a change in structure and strength. At a higher rate of solidification, there is a reduction of the share of eutectic and a decrease in strength.

“Generar capacidad local” es una expresión que se usa con frecuencia en la formulación de proyectos que buscan el desarrollo y la mejora de las condiciones de vida de una población en un territorio determinado. Sin embargo, lograr que esas capacidades se transformen en acciones innovadoras y de mejora no es tarea sencilla. En MAPA la estrategia de transferencia de tecnología ha buscado fomentar un cambio en las prácticas y recomendaciones que hacen los ATA, de forma que éstas incorporen el enfoque de agricultura climáticamente inteligente. Para conseguir esto no solo se ha trabajado en los momentos formativos como estrategia de capacitación, sino en la generación de una comunidad de práctica que estimule procesos de innovación en su quehacer. Transformar palabras en hechos.

La adaptación de la agricultura al cambio y la variabilidad climática no solo requiere de conocimientos en climatología y vulnerabilidad de sistemas de cultivo por parte de todos los que hacen parte del sector. La adaptación requiere que estos conocimientos se transformen en acciones coherentes que se vean reflejadas en un paisaje cada vez más adaptado al cambio y variabilidad climática. Las nuevas actividades o experiencias que los asistentes técnicos agropecuarios –ATA empiezan a incorporar en su actuación deben ser sistematizadas y conocidas por los otros miembros de la red ATA. Esta ola de nuevas acciones va ganando fuerza y es la que consigue ir modelando un paisaje adaptado al cambio climático.

Se dice que “lo que no se evalúa no se mejora” y esta puede ser una entre tantas razones por las cuales el desarrollo tecnológico en materia agropecuaria en muchos casos no se traduce en mejores condiciones de vida de los productores en Colombia. En el mejor de los casos las evaluaciones se limitan a aspectos económicos y financieros que dan cuenta de los posibles beneficios económicos sin tener en cuenta las condiciones escasos y los disponibles. En otros casos las evaluaciones son complejos modelos matemáticos que tratan de simular las condiciones de las unidades productivas con todo el grado de incertidumbre que conllevan estos ejercicios, más aun en aspectos tan importantes como los sociales o culturales

Las parcelas de integración son espacios de aprendizaje en los que se incorpora una opción tecnológica que disminuye la amenaza climática identificada en un sistema de cultivo determinado en la finca de un productor tipo. El objetivo es que los investigadores puedan ajustar en las condiciones reales de producción la implementación y gestión de la opción tecnológica, de forma que con este ejercicio empírico y de diálogo constante con productores y asistentes técnicos agropecuarios puedan obtener recomendaciones y planes de manejo a escala de la región

En este número queremos explicar con más detalle el sistema experto MAPA. Este SE_MAPA fue concebido como una herramienta para la gestión del conocimiento, a partir de la información que el proyecto ha generado. Son conocidas las críticas sobre la cantidad de proyectos que teniendo un acervo de información considerable solo consiguen que quede recogida en informes técnicos y archivos que no trascienden a los ciudadanos en sus territorios. En MAPA hemos querido que la información de climatología, vulnerabilidad territorial y opciones tecnológicas en la lógica de la gestión del riesgo agroclimática quede recogida en una herramienta que no solo la difunda, sino que permita hacer una gestión del ese conocimiento.
Impact of Social Media Usage on Users’ COVID-19 Protective Behavior: Survey Study in Indonesia

Background

Social media have become the source of choice for many users to search for health information on COVID-19 despite possible detrimental consequences. Several studies have analyzed the association between health information–searching behavior and mental health. Some of these studies examined users’ intentions in searching health information on social media and the impact of social media use on mental health in Indonesia.

Objective

This study investigates both active and passive participation in social media, shedding light on cofounding effects from these different forms of engagement. In addition, this study analyses the role of trust in social media platforms and its effect on public health outcomes. Thus, the purpose of this study is to analyze the impact of social media usage on COVID-19 protective behavior in Indonesia. The most commonly used social media platforms are Instagram, Facebook, YouTube, TikTok, and Twitter.

Methods

We used primary data from an online survey. We processed 414 answers to a structured questionnaire to evaluate the relationship between these users’ active and passive participation in social media, trust in social media, anxiety, self-efficacy, and protective behavior to COVID-19. We modeled the data using partial least square structural equation modeling.

Results

This study reveals that social media trust is a crucial antecedent, where trust in social media is positively associated with active contribution and passive consumption of COVID-19 content in social media, users’ anxiety, self-efficacy, and protective behavior. This study found that active contribution of content related to COVID-19 on social media is positively correlated with anxiety, while passive participation increases self-efficacy and, in turn, protective behavior. This study also found that active participation is associated with negative health outcomes, while passive participation has the opposite effects. The results of this study can potentially be used for other infectious diseases, for example, dengue fever and diseases that can be transmitted through the air and have handling protocols similar to that of COVID-19.

Conclusions

Public health campaigns can use social media for health promotion. Public health campaigns should post positive messages and distil the received information parsimoniously to avoid unnecessary and possibly counterproductive increased anxiety of the users.

UNSTRUCTURED

In the wake of the COVID-19 pandemic, video consultation was introduced in general practice in many countries around the world as a solution to provide remote health care to patients. It was assumed that video consultation would find widespread adoption in post–COVID-19 general practice. However, adoption rates remain low across countries in Northern Europe, suggesting that barriers to its use exist among general practitioners and other practice staff. In this viewpoint, we take a comparative approach, reflecting on similarities and differences in implementation conditions of video consultations in 5 Northern European countries’ general practice settings that might have created barriers to its use within general practice. We convened at a cross-disciplinary seminar in May 2022 with researchers and clinicians from 5 Northern European countries with expertise in digital care in general practice, and this viewpoint emerged out of dialogues from that seminar. We have reflected on barriers across general practice settings in our countries, such as lacking technological and financial support for general practitioners, that we feel are critical for adoption of video consultation in the coming years. Furthermore, there is a need to further investigate the contribution of cultural elements, such as professional norms and values, to adoption. This viewpoint may inform policy work to ensure that a sustainable level of video consultation use can be reached in the future, one that reflects the reality of general practice settings rather than policy optimism.
