Adapting to changing concepts of time
Authors: Penz Hermine
Published: August 2020

Time concepts have been developed throughout human history and different academic disciplines have theorized time. What is more, people’s time regimes have changed through adapting to the introduction of new techniques of production. After discussing changing conceptions of time in the life of human beings the article focuses on a science fiction account of a different view of time represented by aliens in the short story “Story of Your Life” by Ted Chiang (2002). The story features interactions of a linguist (and physicists) with aliens. The paper looks at how the main protagonist slowly adapts to the mode of simultaneous time reflected in the alien’s grammar (which means the simultaneity of past, present and future) when learning their language and analyses how this is represented linguistically in the story.
The reality of technological worldviews
Authors: Kaal Bertie
Published: August 2020

There appears to be a silent shift in technological discourse, from adapting technology to people’s needs to adapting people’s needs to new technologies. This shift in ‘direction-of-fit’ is effected by spatio-temporal text-world builders. The analysis of a technological article on self-driving cars serves as an example of a discourse-space approach to identifying the fundamental coordinates of worldview construction, involving Space, Time and Attitude. Results allow a critical evaluation of a one-directional heuristic that suggests user benefits. However, the frame-of-reference and point-of-view mask the socio-political consequences of introducing self-driving cars. The analysis reveals the subjective ground of the argument and challenges a self-assertive, dehumanised positivist attitude to technological innovation. It is argued that the spatial nature of worldview construction directs towards desires and intentions for action.
The adaptability of becoming
Authors: Ferreira Dina Maria Martins , Silva Jony Kellson de Castro
Published: August 2020

This chapter draws upon Karina Buhr’s image of becoming-junglehood in order to contribute to a discussion of the pragmatics of adaptability. Buhr is a Brazilian feminist singer who is interested in recontextualizing terms of a male-dominated tradition on more affirmative grounds. She thus adapts semiotic forms – verbal language and her bodily performance – as disruptive forms, and thereby looks for more liberating grounds of language use. Theoretically, the chapter nuances Buhr’s rationalizations by engaging with Walter Benjamin’s formulations about art and its mechanical reproducibility; with Derrida’s iterability of language; and with Deleuze and Guattari’s articulations of assemblage, subjectivation, and becoming. The paper finally critiques a metaphysics of unity by identifying processes of rupture and adaptability in Buhr’s discursive practices of becoming-junglehood.
Expressing opinions and emotions while travelling on-line
Authors: Mestre Eva M. , Romero-Trillo Jesús
Published: August 2020

New technologies are developed to facilitate our daily lives, and as a result, they also transform our reality and create new communication contexts between humans and machines. Mey (2006) insists on the two-way directivity of adaptation: humans need to adapt to the machine as well as machines need to adapt to humans. Our research investigates the relationship between technology, language, context and emotions, with special attention to the use of verbs and adjectives in personal descriptions of travel experiences. Specifically, two corpora of travel and tourism analyse how users share their experiences, and recommend or criticize certain itineraries and places, depending on their own likes and dislikes.

Authors: Fang Hongli , Shi Yongsen , Zhou Miaoting , Niu Qigui
Published: August 2020

The influences of n-Hexadecane and naphthalene on anaerobic digestion in batch tests were investigated. The batch kinetic analysis showed that the maximum methane accumulations (141.18 mL of n-Hexadecane and 146.76 mL of naphthalene) and production rates (20.48 mL/h of n-Hexadecane and 20.88 mL/h of naphthalene) were obtained while adding with 30 mg/L n-Hexadecane and 2 mg/L naphthalene, respectively. However, a significant inhibition ratio of 10% was observed at 100 mg/L of n-Hexadecane and 20 mg/L of naphthalene, respectively. The 3D-EEM results showed that the naphthalene was degraded by related microorganism as potential carbon source with concentration lower than 10 mg/L. In addition, the microbial community analysis indicated that the abundance of hydrotrophicMethanolineaandMethanobacteriumincreased from 7.92% to 12.76% as the increase n-Hexadecane, while decreased from 13.01% to 9.07% with increase of naphthalene. Contrastly, the acetoclasstic methanogens were increased due to the well synthetic action with syntrophic VFA-oxidizing bacteria.

Authors: Zhang Yanlan , Liu Jinyan , Guo Guibao , Lin Zhihui
Published: August 2020

NiFe2O4 with high theoretical capacity, natural abundance as well as low cost exhibits tremendous potential as the electrode for lithium ion battery. Nevertheless, the great volume change upon the charge-discharge cycling gives rise to pulverization of NiFe2O4 electrode. The electron transport pathways are broken down, and ultimately, the cycling stability and reversible capacity fade rapidly, which restricts its commercial applications. Consequently, it is necessary to consider nano-size effect, interface property, defects and hybridization to satisfy the requirement of practical application. In this review, we comprehensively overview and analyze the latest progress in NiFe2O4-based anode, covering the representative synthesis method and advanced structure to realize improved Li+ storage performance. Furthermore, we objectively evaluate the Li+ storage performance of NiFe2O4-based anode materials and dissect the existing problems. Finally, an outlook for the development of advanced NiFe2O4-based anode materials is provided.

Authors: Ma Jianrong , Zhang Guangzhi , Ren Fuming
Published: August 2020

In the process of urban modernization and rapid construction, the construction and reconstruction of large-scale construction projects such as subways, underground pipe corridors, and housing construction facilities are accompanied by a large amount of construction waste. A huge amount of construction waste not only occupies a large number of land resources, but also affects air quality, pollutes waters, destroys city appearance and environmental sanitation, and has potential safety hazards. In the long run, it also affects urban development space and shortens the city life cycle. At present, there are many shortcomings in China’s policy management, classification and measurement, reduction technology, transportation recovery, recycling and other aspects of construction waste. Especially from the source, there is a lack of research on the source characteristics of construction waste, which makes the quantitative quantification of various construction wastes impossible to achieve construction, accurate management, and control of waste. This study takes the urban subway construction project as the research object, through the field investigation, literature review and other methods, analyses the classification and source of underground construction waste by the project unit construction process as the framework, and analyses the corresponding construction waste according to the investigation and data collection. The reduction measures implemented.

Published: August 2020

The project team selected eight typical buses (CNG, LNG, gasoline- electric hybrid, gas-electricity hybrid) at different emission stages in the built-up area of Tangshan City to test the emission of gaseous pollutants and particulate matter under actual road conditions, systematically evaluated, analyzed and compared the test results, and established the VSPbin emission rate database and emission factor list of typical urban buses in built-up areas based on the actual travelling characteristics of Tangshan. In this study, four cycles of acceleration, constant speed, deceleration and idle speed were selected to analyze the travelling cycle of buses in Tangshan. The results showed that the proportion of acceleration was higher, while deceleration also had a higher proportion; The area of bus travelling was mainly in the urban area, and the travelling cycles were relatively complicated, so there were frequent acceleration and deceleration during the travelling process. For the buses, with the raising of emission standards and the use of hybrid technology, the emissions of CO2 and NOx from the buses at National IV were decreased by 13% and 53.5% respectively compared with those from the buses of the same tonnage at National III; The emissions of CO2 and NOx from the nature gas-electric hybrid buses at National V were reduced by 20% and 18.8% respectively compared with those from the nature gas-fueled buses of the same tonnage at National V.

Published: August 2020

The output of greenhouse gases resulting from Tibet’s crop farming over the years 1991 to 2015 has been estimated, and the Logarithmic Mean Divisia Index model was used to deduce the influence of the various factors underlying these greenhouse gas emissions. From 1991 to 2015, the overall carbon emissions of the Tibetan plantation industry showed a “U” -shaped change trend. Carbon emissions from plantation mainly include nitrogenous oxide and rice field methane. The LMDI decomposition results showed the economic factor (SI) and the efficiency factor (CI) determined the development trend of the total effect. The CI is an important contributor to the reduction of carbon emissions, whereas CI is important inhibiting carbon emissions. Labor factors (AL) contribute to agricultural carbon emissions. SI and AL have an upward trend in promoting agricultural carbon emissions.

Published: August 2020

With the continuous recommendation of the urbanization process in China, the production of construction waste is also increasing. At present, the utilization of construction waste resources in China is relatively low, mostly landfilling disposal. The environmental problems caused by landfill disposal are becoming more and more serious, but also a great waste of resources. Fine classification of construction waste source is the premise and key to promote the precise management and control of construction waste. This paper makes a thorough investigation and literature analysis on the classification methods of construction waste in developed countries abroad and the Post-disposal modes brought by classification. Based on the current situation and existing problems of classification of construction waste in China, six first-level classification and 28 second-level classification are proposed. The results of construction waste and the feasibility of the results are discussed and analyzed in order to provide reference for the classification of buildings in China.

Published: August 2020

In order to realize the ultra-low emission of flue gas in a 600 MW coal-fired unit, the original demister of desulfurization tower (two-stage ridge demister + one-stage tube demister) was transformed into a Condensing dust removal and demisting device. The Condensing dust removal and demisting device is composed of a three-stage ridge type high-efficiency mist eliminator and a condensing wet film layer. In addition, it is equipped with a cooling station outside the tower composed of a spray cooling water pump and a closed cooling equipment under 100% and 50% working conditions, by adjusting the operation mode of the cooling station and controlling the operation. The slurry droplet emission of the desulfurization system under different working conditions, the overall collaborative dust cleaning efficiency and the SO3 removal rate were tested on site. The test results show that the heat exchange of the cooling station has a great influence on the operation effect of the Condensing dust removal and demisting device, and improving the heat exchange of the cooling station is helpful to improve the removal effect of slurry drop, dust and SO3.

Published: August 2020

In the process of planting, selling and processing vegetables, a large number of wastes will be produced. If these wastes are used as resources for secondary use, they will produce great value. At present, the utilization rate of vegetable waste is very low, and the related technology research is also lagging behind. At present, China actively advocates the development of green economy, energy conservation and emission reduction, and improve the utilization rate of resources. As an important available resource, vegetable waste has received great attention. Therefore, the research on vegetable waste recycling technology is deepening. Based on the analysis of the current situation of vegetable waste recycling treatment, this paper proposes a new model of vegetable waste treatment, which combines rapid volume reduction treatment with biochemical technology to produce organic fertilizer, in order to provide a reference for the reuse of vegetable waste.

Published: August 2020

We examined the decolorization of Acid Red B (ARB) in glow/spark discharge plasma (GDP/SDP). It is found that the decolorization of ARB was observably higher in GDP than in SDP. After 16 min treatment, ARB decolorization rate reached 97.16% with the energy efficiency of 7.16 kg/kW-h in GDP, and 92.76% with 0.84 kg/kW-h energy efficiency in SDP. The average yield of plasma oxidants were 1.73 kg/kW-h in GDP, and 0.14 kg/kW-h in SDP. Some factors, which probably affect the decolorization of ARB aqueous solution, such as hydroxyl radical and ultraviolet radiation etc. were investigated. The results showed that plasma oxidation, especially hydroxyl radical might be main factors accounting for ARB decolorization.
Reasonable Application and Interpretation of Effective Stress Principle in Shale Reservoir Mining
Authors: Li Yalong , Hu Zhiming , Liu Xiangui , Duan Xianggang
Published: August 2020

This paper explores the effective stress characteristics of shale reservoir mining from the perspective of mechanics. The results show that the decrease of the pore fluid pressure and the increase of the effective stress acting on the active zone are not a simple linear relationship, but a nonlinear relationship that increases rapidly and then slows down. In the post-fracturing development process of shale reservoirs, the reservoirs in the early stage of production will produce uneven deformation and structural damage. The mechanical behavior of the reservoir is mainly characterized by plastic deformation. As mining progresses, reservoir failure and fracture areas are compacted or supported. The mechanical behavior of the reservoir is mainly characterized by elastic deformation. In the stress cloud diagram, the stress of the overlying strata presents a certain arched distribution. This structural effect makes the equivalent stress difference in the reformed area increase continuously, and the pressure bearing by the structure to the overlying strata will be greater. Therefore, he extent of the increase in the true effective stress borne by the transformation area will decrease.

With the improvement of living standards, the national coverage of heaters is also higher. From the original only the northern part of the installation of heating devices, to the south of the central area has also installed heaters, and even some people in the southern area installed heaters. With the increase in sales volume and fierce competition, companies need to reform and innovate products to meet the higher requirements of customers for energy-saving effects, comfort and safety. The design of the heater involves theories of structure, integrated circuit, program algorithm, aerodynamics, heat transfer and so on. Due to the technical level and cost constraints of enterprises, few companies can produce safe, energy-saving, moisturizing and comfortable heaters suitable for the public. In this study, the green energy-saving circulating heater of ECO intelligent system adopts the incremental ECO processing algorithm, with the single-chip STC89C52 as the main control chip system, combined with the peripheral STC89C52 temperature data acquisition, HIH-3010 humidity data collector, A/D Conversion module, keyboard settings, LCD1602 liquid crystal display and other circuit modules. This design realizes the temperature value that the heater provides the user with the optimum indoor temperature value and sets the heating according to the user’s needs. When the set temperature value is reached or the temperature is high, the controller will control the heating element to reduce power or automatically power off to achieve safe power saving effect.

Authors: Zhong Wen , Zhong Changbiao , Zheng Minggui
Published: August 2020

Land consolidation has an important impact on regional poverty reduction. It gradually integrates into the precise poverty reduction strategy and becomes one of the powerful measures to innovate the poverty reduction and development methods. Based on the data of 31 provinces in China from 2005 to 2015, this paper uses VAR model to make an empirical study on the dynamic causal relationship between land consolidation and regional poverty management. The research shows that (1) there is an interactive relationship between land consolidation and poverty management, and it is a positive feedback function of each other, indicating that land consolidation has a positive promoting effect on regional poverty management; (2) According to the impulse response function diagram, the impact of land consolidation on poverty reduction has been rising rapidly from the first stage to the second or so stage and declining until the third or so stage is reduced to zero. The impact of poverty reduction on land consolidation shows a downward-upward fluctuation until the fifth or so stage is reduced to zero. This shows that if a positive impact is given, land consolidation and poverty reduction will interact. (3) From the variance decomposition chart, it can be found that land consolidation and regional poverty alleviation interact with each other. After Phase 2, both parties have maintained a high level towards each other.
In Situ Experiment and Analysis of the Attenuation Characteristics of Environmental Vibrations Based on Frequency Sweep Method
Authors: Xu Zhaogang , Lou Yu , Chen Liu
Published: August 2020

Analysis of the attenuation characteristics of environmental vibrations with different frequencies is of great benefit for preventing many vibration-related problems. This study carried out an in situ experimental study on the attenuation characteristics of a series of single frequency ground vibrations caused by harmonic excitations. An electromagnetic vibration excitation system was adopted to generate harmonic excitations at frequencies varying from 10 Hz to 80 Hz with steps 5 Hz. 5 low frequency, 1 component, 991B vibration sensors fastened on the ground surface were used for the measurement of the vertical velocity time histories of ground vibrations at 5 test points with different distances from the vibration source. The vibration level in terms of the vertical peak particle velocity of single frequency ground vibrations in general decayed monotonically but nonlinearly with distance, however, the attenuations of 15 Hz, 45 Hz, 65 Hz and 75 Hz ground vibrations were oscillatory due to vibration interference on the ground surface. The attenuation of single frequency ground vibrations was more rapid in the zone close to the vibration source than that in the zone far away. This study demonstrates that comparison of the attenuation characteristics of high and low frequency ground vibrations should take into account the difference in the amplitudes of the corresponding ground vibrations.

Published: August 2020

The concept of green growth has been put forward for many years in China. After years of practice, the performance of green growth in all provinces of China has changed, but it has not been systematically evaluated. Based on OECD’s green growth framework, this study develops an indicator system of green growth evaluation suitable for China’s provinces, and then evaluates the green growth levels in different regions of China. The result shows that China’s regional green growth is uneven. The green growth performances in the eastern coastal provinces are generally higher than that of western provinces. After identifying the advantages and disadvantages of different provinces in green growth, this paper analyses the causes of these differences. This research could offer a valuable reference for regions that adopt green growth as their development mode.

Authors: Khan Madiihah S I , Fang Ping
Published: August 2020

Worldwide housing shortages experienced by many developing countries are central to much international debate as the number of people without decent shelter continues to reach unprecedented levels. Housing demands in such countries are usually met by the adoption of conventional approaches that are not always sustainable. Housing affordability and sustainability are therefore crucial to the provision of housing, which sustains its inhabitants economically, socially and environmentally, while ensuring the sustainability of the planet as a whole. Through a scoping study, this paper identifies current construction and design approaches, building features and criteria and policy options favoring the application of sustainability in affordable houses. In the joint implementation of sustainable and affordable housing, a number of practices, such as lean construction methods, building design to improve energy efficiency and reduce costs, and government contributions to planning incentives, subsidies and country-level policies, were found to be effective.

Published: August 2020

Chinese ink nanofluids were prepared successfully by “two-step” method. The optical properties of Chinese ink nanofluids were investigated. And the effects of the base fluid types and ultrasonic time on their dispersion stability also were investigated. Results show that Chinese ink have high absorption characteristics and very low transmittance on light radiation in the wavelength range of 190-1100 nm; The dispersion stability of nanofluids increases first and then decreases with the increase of ultrasonic dispersion time. There is an optimal ultrasonic dispersion time of 90 min; the base fluid has a certain influence on the dispersion stability of Chinese ink nanofluid, among which DMF base solution has the best dispersion stability, followed by thermal conductive oil. Ethanol has no obvious improvement compared with water, both of which have lower dispersion stability than DMF and thermal conductive oil. This research provides a fundamental guidance for the preparation of Chinese ink nanofluids and their further application in Solar photo-thermal conversion.

Authors: Müller C , Touzani R S , Betke U , Krüger M
Published: August 2020

The present study addresses the microstructural evolution and mechanical properties of three different cast V-5X (X = Nb, Ti and Mo) alloys. All alloy compositions are located in the vanadium solid solution (VSS) phase field in their respective phase diagrams. While the alloys V-5Ti and V-5Nb solidified as single-phase VSS after arc-melting, the alloy V-5Mo additionally shows some amount of molybdenum solid solution (MoSS) in the resulting as-cast microstructure. To improve the mechanical database on vanadium-based alloys, room temperature compression tests were performed and microhardness measurements were carried out by the Vickers indentation method. The lattice parameters were determined by X-ray diffraction analysis and they were calculated using the density functional theory. By carrying out these experiments, the data available for vanadium-based alloys were extended being now available for further optimization of novel V-Si-B high temperature alloys.

A local sensitivity analysis in Landau damping for the kinetic Kuramoto equation with random inputs
Authors: Ding Zhiyan , Ha Seung-Yeal , Jin Shi
Published: August 2020

We present a local sensitivity analysis in Landau damping for the kinetic Kuramoto equation with random inputs. The kinetic Kuramoto equation governs the temporal-phase dynamics of the one-oscillator distribution function for an infinite ensemble of Kuramoto oscillators. When random inputs are absent in the coupling strength and initial data, it is well known that the incoherent state is nonlinearly stable in a subscritical regime where the coupling strength is below the critical coupling strength which is determined by the geometric shape of the distribution function for natural frequency. More precisely, the Kuramoto order parameter measuring the fluctuations around the incoherent state tends to zero asymptotically and its decay mode depends on the regularity(smoothness) of natural frequency distribution function and initial datum. This phenomenon is called Landau damping in the Kuramoto model in analogy with Landau damping arising from plasma physics. Our analytical results show that Landau damping is structurally robust with respect to random inputs at least in a subcritical regime. As in the deterministic setting, the decay mode for the derivatives of the order parameter in the random space can be either algebraic or exponential depending on the regularities of the initial datum and natural frequency distribution, respectively, and the smoothness for the order parameter in the random space is determined by the smoothness of the coupling strength.

Authors: Smith Kathryn E , Mason Tyler B , Schaefer Lauren M , Anderson Lisa M , Critchley Kobe , Crosby Ross D , Engel Scott G , Crow Scott J , Wonderlich Stephen A , Peterson Carol B
Published: August 2020

Background

Stress is a dynamic construct that predicts a range of health behaviors and conditions, including binge eating and excess weight. Thus far, there have been limited and inconsistent findings regarding stress responses in binge-eating disorder (BED) and insufficient consideration of temporal patterns of stress responses across the weight spectrum.

Purpose

The present study used ecological momentary assessment (EMA) to examine stress reactivity (i.e., the magnitude of the initial stress response), recovery (i.e., how long the stress response lasts before returning to baseline), and pileup (i.e., accumulation of repeated experiences of stressors and responses over time) as predictors of binge-eating symptoms (BES) and food craving in BED.

Methods

Adults with BED (N = 115) completed a 7 day EMA protocol assessing stressful events, perceived stress, binge eating, and food craving prior to being randomized to a behavioral intervention.

Results

Generalized estimating equations indicated that moments of greater stress pileup predicted greater subsequent BES (within-person effect). Participants with higher perceived stress and pileup reported greater overall BES and craving, and those with better recovery reported higher overall craving (between-person effects).

Conclusions

Findings highlight the importance of considering the dynamic nature of stress responses and, particularly, that the accumulation of stress over the day is an important trigger for BES.

Current histologic definitions, including 3 separate proposed definitions for SH-HCC, were applied to tumors previously characterized as clear cell HCC. Histologic and clinical variables were analyzed.

Results

Of 66 HCCs, 51 (77%) were classified using modern definitions, including 34 SH-HCCs, 15 S-HCCs, and 2 C-HCCs. Compared with the most permissive SH-HCC definition, the other 2 definitions designated 30 and 25 SH-HCCs (−12% and −26% cases, respectively). Unsurprisingly, S-HCC and SH-HCC were associated with steatotic clear cells (P < .0001). S-HCC was also more typically early type and low grade (P = .0017). The remaining unclassified clear cell HCCs were associated with flocculent (rather than steatotic or optically clear) cytoplasm (P < .0001) but otherwise demonstrated no discrete clinical-pathologic profile.

Conclusions

Current definitions could be used to reclassify the majority of “clear cell” HCCs. The subtypes are significantly correlated with a few variables, suggesting valid differences of the subtypes, although additional study is warranted, particularly to standardize the definition of SH-HCC.

BACKGROUND

MicroRNAs serve as important regulators of the pathogenesis of cardiac hypertrophy. Among them, miR-183 is well documented as a novel tumor suppressor in previous studies, whereas it exhibits a downregulated expression in cardiac hypertrophy recently. The present study was aimed to examine the effect of miR-183 on cardiomyocytes hypertrophy.

METHODS

Angiotensin II (Ang II) was used for establishment of cardiac hypertrophy model in vitro. Neonatal rat ventricular cardiomyocytes transfected with miR-183 mimic or negative control were further utilized for the phenotype analysis. Moreover, the bioinformatics analysis and luciferase reporter assays were used for exploring the potential target of miR-183 in cardiomyocytes.

RESULTS

We observed a significant decreased expression of miR-183 in hypertrophic cardiomyocytes. Overexpression of miR-183 significantly attenuated the cardiomyocytes size morphologically and prohypertrophic genes expression. Moreover, we demonstrated that TIAM1 was a direct target gene of miR-183 verified by bioinformatics analysis and luciferase reporter assays, which showed a decreased mRNA and protein expression in the cardiomyocytes transfected with miR-183 upon Ang II stimulation. Additionally, the downregulated TIAM1 expression was required for the attenuated effect of miR-183 on cardiomyocytes hypertrophy.

CONCLUSIONS

Taken together, these evidences indicated that miR-183 acted as a cardioprotective regulator for the development of cardiomyocytes hypertrophy via directly regulation of TIAM1.

Objective

To determine whether performance on the Latin American Spanish version of the Face-Name Associative Memory Exam (LAS-FNAME) can differentiate between cognitively intact carriers of an autosomal dominant Alzheimer’s disease mutation (E280A) in Presenilin-1, who are destined to develop early-onset dementia, from matched non-carriers. We also sought to examine whether LAS-FNAME performance is associated with amyloid-β and regional tau burden in mutation carriers.

Methods

35 cognitively intact mutation carriers (age range 26–41), 48 matched non-carriers (aged 27 to 44), and 19 symptomatic carriers (13 with subjective cognitive concerns, 6 with mild cognitive impairment [MCI]) completed the LAS-FNAME. A subset of participants (31 carriers [12 symptomatic] and 35 non-carriers) traveled from Colombia to Boston to undergo positron emission tomography (PET) using Pittsburgh compound B to measure mean cortical amyloid-β and Flortaucipir for regional tau tangles. ANOVA analyses and Spearman correlations were used to examine group differences and relationships among LAS-FNAME performance, Aβ and tau accumulation.

Results

Compared to non-carriers, cognitively intact carriers had lower scores on the LAS-FNAME total scores (p = .040). Across all carriers (including symptomatic carriers), higher levels of amyloid-β (r = −.436, p = .018) and regional tau in the entorhinal (r = −.394, p = .031) and inferior temporal cortex (r = −.563, p = .001) were associated with lower LAS-FNAME total scores (see Figure).

Conclusions

Performance on the LAS-FNAME differentiated between cognitively intact mutation carriers from non-carriers, and was associated with greater amyloid and tau burden when examining all carriers. Findings suggest that the LAS-FNAME is sensitive to early clinical and pathological changes and can potentially help track disease progression in Spanish-speaking individuals.
A-06 Current Norms May Overestimate Rates of Neurocognitive Impairment among American Indian and Alaskan Native Adults.

Objective

Currently available normative data subsume American Indian and Alaskan Native (AI/AN) populations within the non-Latinx white (NLW) ethnoracial group. The classification accuracy of such norms among AI/AN remains unknown. This cross-sectional study aims to identify whether disparities exist in the rates of neurocognitive impairment (NCI) between AI/AN and NLW adults. < br>
 

Method

Two hundred community-dwelling adults (50% NLW; 50% Male; M Age = 42 ± 14 years; M Education = 13 ± 3 years) completed comprehensive neurocognitive, quality of education (Wide Range Achievement Test- 4 [WRAT-4]), neuromedical, urine toxicology, and psychiatric/substance use evaluations. Average T-scores were calculated using widely used demographically corrected (age, gender, education) NLW norms to identify NCI (> 1 SD; e.g., Heaton et al., 2004; Heaton & Marcotte, 2000). A comorbid condition propensity score (CCPS) identified the probability to which comorbid conditions (e.g., Heaton et al., 2010) informed ethnoracial identity.

 

Results

After adjusting for WRAT-4 and CCPS, the results of a logistic regression analysis demonstrated a significant ethnoracial disparity in risk for NCI (X2(3) = 13.88, p<.01, R2 = .07), such that the AI/AN group was at 2.52 times higher odds (32.3% vs. 16.0, CI: 1.15–5.46, p = .01, Cohen’s d = .51) for NCI in comparison to the NLW group.

 

Conclusions

Published norms for NLW adults may overestimate impairment in AI/AN adults. Thus, population-specific normative data are needed to clarify the classification accuracy of neurocognitive impairment and possible disparities in neurocognitive disorders (e.g., HIV-associated neurocognitive disorders) among AI/AN adults. Future work should replicate these findings among other diverse populations (e.g., Caribbean, Middle Eastern) lacking population-specific normative data.876199.
