Introducción: Actualmente se ha observado que la hipovitaminosis D y la obesidad pueden influir en el desarrollo de enfermedad cardiovascular en el futuro.

Objetivo: Identificar la asociación entre deficiencia de vitamina D y factores de riesgo cardiometabólicos en los pacientes pediátricos del noroeste de México.

Materiales y métodos: se incluyeron niños de 6 a 15 años, se les midieron variables somatométricas, niveles séricos de colesterol total, C-HDL, C-LDL, triglicéridos, glucosa, insulina, vitamina D e índice HOMA-IR. Se identificó la asociación de factores de riesgo cardiometabólicos y la deficiencia de vitamina D, mediante la prueba de Chi cuadrado.

Resultados: De los 114 pacientes evaluados, se detectó eutrofia en 42.1%, sobrepeso en 12.3%, obesidad en 41.2% y desnutrición en 4.4%. La prevalencia de deficiencia en vitamina D, insuficiencia y suficiencia fueron 18.4%, 27.2% y 54.4% respectivamente. La deficiencia de vitamina D mostró mayor predominio en pacientes con obesidad (27 %). La hipertrigliceridemia se asoció estadísticamente con deficiencia de vitamina D (p 0.041). Se observaron correlaciones inversas  entre niveles de vitamina D con HOMA (r=-0.191; p=0.41), score Z IMC (r=-0.210; p=0.025) e insulina (r=-0.227; p=0.015).

Conclusiones: La deficiencia de vitamina D se asocia en niños con un IMC elevado y resistencia a la insulina, lo cual puede acelerar el desarrollo de síndrome metabólico, diabetes mellitus tipo 2 y enfermedad cardiovascular.

Verbs of hiding and their combinability with locative affixes in Adyghe
Authors: Bagirokova Irina G.
Published: August 2022

This paper investigates the semantics of hiding in Adyghe from a typological perspective. There are four verb stems: ʁebəλə- ‘to hide’, wəχʷəme- ‘to protect, to cover up’, wəŝefə- ‘to conceal’, and xeḳʷ ečʼ̣ e- ‘to mix, to blend in’. The central verb of the field, ʁebəλə- ‘to hide’, describes situations where the object is put somewhere to be out of sight (e.g. ‘to hide money into the safe’). It combines with the same locative affixes as standard verbs of motion do. In current usage, the verb wəχʷəme- stands for ‘to protect’, whereas the locative prefix čẹ - ‘under’ changes its meaning to ‘to cover up, to hide’ (e.g. ‘to get the picture covered in dust’). The verb wəŝefə- ‘to conceal’ denotes a specifi c, “passive” mode of hiding, the primary goal of which is to keep the object secret (e.g. ‘to conceal the income from the taxation authorities’). And the verb xeḳ ʷečʼ̣ e- ‘to mix, to blend in’ expresses the idea of hiding something amongst multiple entities (e.g. ‘to disappear into the crowd’). As is shown, the combinability of these four verbs with certain affixes, including locatives, is highly determined by their lexical meaning. The research serves to clarify the semantics of several verb stems and locative affixes in Adyghe and is considered to contribute to the general typology of hiding.

Authors: Ortiz Cabrera Iván Alexander , Montenegro Córdoba Jhoana Patricia
Published: August 2022

Además de una enorme crisis de salud pública, la pandemia generada por el nuevo virus SARS-CoV-2 (causante del covid-19) ha generado una profunda crisis económica y social; detonando voces importantes que demandan profundizar el desarrollo sostenible y “regresar mejor” en una era poscovid-19. El proceso de reactivación económica pospandemia presenta riesgos y potencialidades que deben ser considerados. Hay una necesidad de generación de empleos y crecimiento económico en niveles más acelerados para recuperar las pérdidas y reducir el sufrimiento social. Cabe reconocer que no se ha evidenciado niveles de adopción de medidas semejantes en lo que atañe a desafíos como el cambio climático, la biodiversidad y la desigualdad; sin embargo, los cambios casi siempre llegan tras una crisis, y precisamente el cambio es el motor de todo progreso humano.

Authors: Apriliyanti Retno , Verawati Sindy Septi , Nurhayati Susi
Published: August 2022

Background: breast self-examination is a systematic breast self-examination by a woman for the purpose of detecting abnormalities in the breast which is carried out every month. To increase adolescent self-awareness, health education is needed, namely peer counseling which helps peer counselors. In addition to peer activities, the provision of leaflets about breast self-examination also helps counseling in providing informationPurpose: this study was to know the effectivity of peer counselor counseling and leaflets about breast self-examination towards students’ self-awareness.Methods: this study uses a Quasy Experiment approach a pre-test and post-test without control group design. The research sample was 40 respondents. Collecting data used a questionnaire that has been tested by expert on Maternity Nursing. Data analysis used the paired sample t-test in the paired group while the independent sample t-test in the unpaired groupResults: the results that self-awareness before the group was given peer counselor treatment had an average of 67.10 and given after peer counselors about breast self-examination had an average of 100.50 while in the control group self-awareness before being given leaflets an average of 68.50 and after being given leaflets an average of 73.35. There are differences in peer counselors regarding breast self-examination on self-awareness of students with p value = 0.000.Conclusion: follow-up process is still needed to increase self-awareness in carrying out breast self-examination and coordination from the school.

Background: the number of confirmed or positive cases of Covid-19 has increased significantly.  However, the behavior and awareness of the community to work together to fight Covid-19 is still low. Education through various methods and media is an important component in adapting to new normal life. The campus community is expected to be a pioneer in preventing the spread and transmission of covid-19. Purpose: to develop a virtual education audiovisual model for adapting to new normal, and to assess its effect on the behavior of the campus community in preventing the spread and transmission of covid-19.Methods: the research designs used Research and Development (RD) and true - experimental design with control group. The 306 respondents were recruited in this research by randomized. Data collection using a questionnaire assisted by the google form program. Data were analyzed using the Wilcoxon test and the Mann Whitney test.Results: the results of the study showed that the virtual education audiovisual model with adaptation to new normal had an effect on increasing knowledge (p 0.0001), increasing positive attitudes (p 0.0001), and actions (p 0.0001) of the campus community. The total mean score of campus community behavior was in the range 0-75, before treatment was 65.69 (SD + 5.99) and after 73.52 (SD + 2.68) with a difference of 7.83 (p 0.0001).Conclusion: the virtual education audiovisual model of the new normal adaptation had improved the behavior of the campus community in preventing the spread and transmission of covid-19.
What Biological Factors, Social Determinants, and Psychological and Behavioral Symptoms of Patients with Mild Alzheimer’s Disease Correlate with Caregiver Estimations of Financial Capacity? Bringing Biases Against Older Women Into Focus
Authors: Giannouli Vaitsa , Tsolaki Magda
Published: August 2022

This study examines the connection between biological factors, social determinants, and behavioral and psychological symptoms of dementia (BPSD) and the estimations of financial capacity made by caregivers of mild AD patients in Greece. Financial capacity estimations negatively correlated with biological sex of the patients (female), but Neuropsychiatric Inventory (NPI) scores were statistically lower for older females. BPSD (measured with NPI) was found to negatively correlate with estimates of financial capacity. The existence of delusions-hallucinations was reported in all males. No correlations were found between financial capacity estimations, actual cognitive and financial capacity performance, and all other included biological and social characteristics of the patients as well as their caregivers.

Published: August 2022

BACKGROUND: Osteoporotic vertebral compression fractures (OVCFs) are the most common complication of osteoporosis, a worldwide disease that disturbs the elderly. OBJECTIVE: The purpose of the study was to comprehensively compare the clinical efficacy of unilateral percutaneous kyphoplasty (UPKP) and bilateral percutaneous kyphoplasty (BPKP) when treating OVCFs and evaluate their ability to maintain the outcomes in a 2-year follow-up. METHODS: From January 2015 to December 2016 a total of 79 patients with OVCFs were included in the study. They were divided into UPKP group and BPKP group. Subsequently, perioperative data, radiological outcomes, clinical outcomes, and complications were compared between two groups. The follow-up consultation was 3 months, 1 year, and 2 years after the operation. RESULTS: 37 of patients (14 males, 23 females) were allocated to the UPKP group and 42 patients (13 males, 29 females) were treated with BPKP. The duration of operation and injected cement volume were significantly higher in the BPKP group than those of the UPKP group. BPKP achieved significantly higher improvement in middle height and volume of the fractured vertebral body than UPKP did. There were significantly higher losses of anterior, middle height and volume of the fractured vertebral body in the UPKP group at 2-year follow-up than in the BPKP group. At the final follow-up, Oswestry Disability Index (ODI) of BPKP group was lower than that of UPKP group. CONCLUSION: Both UPKP and BPKP achieve satisfactory radiological and clinical outcomes when treating OVCFs. However, in a 2-year follow-up, BPKP maintains vertebral height restoration, volume of vertebral body, and ODI better than UPKP do.
Non-Pharmacologic Interventions for Hispanic Caregivers of Persons with Dementia: Systematic Review and Meta-Analysis
Authors: Dessy Alexa , Zhao Amanda J. , Kyaw Kay , Vieira Dorice , Salinas Joel
Published: August 2022

Background: As the Hispanic/Latino (HL) population grows, so too does the need for HL family caregivers for persons with dementia. HL caregivers tend to have less education, lower health literacy, and lower income, each uniquely compounding burden. Research is needed to appropriately tailor interventions for this population. Objective: A systematic review and meta-analysis was conducted to 1) provide an updated review of non-pharmacologic intervention studies for HL dementia caregivers, 2) characterize promising interventions, and 3) highlight opportunities for future research. Methods: Databases were searched for articles evaluating non-pharmacologic interventions for HL dementia caregivers. Studies were excluded if target populations did not include HLs or if no intervention was delivered. Data were extracted and random effects meta-analysis was performed on two primary outcomes: caregiver depression and burden. Effect sizes were calculated as pre- and post-intervention standardized mean differences (SMD), and further depression subgroup meta-analysis was performed. Other secondary outcome measures (e.g., perceived social support, caregiver knowledge, anxiety) were evaluated qualitatively. Results: Twenty-three studies were identified. Most included multiple components pertaining to psychosocial support, caregiver education, and community resource facilitation. Many studies were successful in improving caregiver outcomes, though intervention design varied. Meta-analysis revealed minimal to moderate heterogeneity and small effect size in improving depressive symptoms (SMD = –0.31, 95% CI –0.46 to –0.16; I2 = 50.16%) and burden (SMD = –0.28, 95% CI –0.37 to –0.18; I2 = 11.06%). Conclusion: Although intervention components varied, many reported outcome improvements. Future studies may benefit from targeting physical health, addressing sociocultural and economic contexts of caregivers, and leveraging technology.
Triple Network Model-Based Analysis on Abnormal Core Brain Functional Network Dynamics in Different Stage of Amnestic Mild Cognitive Impairment
Authors: Li Chenxi ,   Alzheimer’s Disease Neuroimaging Initiative, Li Youjun , Wu Jianqian , Wu Min , Peng Fang , Chao Qiuling
Published: August 2022

Background: Amnestic mild cognitive impairment (aMCI) is considered to be a transitional stage between Alzheimer’s disease (AD) and normal cognitive state because it has the same clinical symptoms as AD but with lower severity. Studies have confirmed that patients with aMCI are more likely to develop to AD. Although studies on resting state functional connectivity have revealed the abnormal organization of brain networks, the dynamic changes of the functional connectivity across the scans have been ignored. Objective: Dynamic functional connectivity is a novel method to reveal the temporal variation of brain networks. This paper aimed to investigate the dynamic characteristics of brain functional connectivity in the early and late phases of aMCI. Methods: Based on the “triple network” model, we used the sliding time window approach to construct dynamical functional networks and then analyzed the dynamic characteristics of the functional connectivity across the entire scan. Results: The results showed that patients with aMCI had longer dwell times in weaker network connection than in the strong network. The transitions between different states become more frequent, and the stability of the patient’s brain core network deteriorates. This study also found the correlation between the altered dynamic properties of the core functional networks and the patient’s clinical Mini-Mental State Examination assessment scale sores. Conclusion: This study revealed that the characteristics of dynamic functional networks constructed by the core cognitive networks varied in distinct ways at different stages of aMCI, which could provide a new idea for exploring the neuro-mechanisms of neurological disorders.
Why neural networks in the first place: a theoretical explanation
Authors: Contreras Jonatan , Ceberio Martine , Kosheleva Olga , Kreinovich Vladik
Published: August 2022

Neural networks – specifically, deep neural networks – are, at present, the most effective machine learning techniques. There are reasonable explanations of why deep neural networks work better than traditional “shallow” ones, but the question remains: why neural networks in the first place? why not networks consisting of non-linear functions from some other family of functions? In this paper, we provide a possible theoretical answer to this question: namely, we show that of all families with the smallest possible number of parameters, families corresponding to neurons are indeed optimal – for all optimality criteria that satisfy some reasonable requirements: namely, for all optimality criteria which are final and invariant with respect to coordinate changes, changes of measuring units, and similar linear transformations.

The FAO Data Lab on statistical innovation and the use of big data for the production of international statistics
Authors: Fabi Carola , Mongeau Ospina Christian A. , Rosero Moncayo José , Silva e Silva Luís G.
Published: August 2022

Data is an extremely important intangible good, but official data is not always available. It may be scarce for many reasons, among which: low statistical capacities, poor funding for data and statistics, weak data dissemination and use culture. A solution to fill data gaps needs to consider that there is data made available on the web, usually coming in an unstructured way, that can be combined with innovative methods to generate relevant information. National and international organisations need to engage with new data sources and methods considering the crisis of traditional data collection systems that causes data gaps. In this light, FAO created in 2019 the “Data Lab for statistical innovation” to fill such gaps by modernising the Organization’s statistical business, which means improving the timeliness and granularity of data collection, providing automated analysis, and capturing early warning signals. It does so through the use of cutting-edge technologies (such as web scraping, text mining, geo-spatial data analysis and artificial intelligence) and by introducing nonconventional data sources (social media, online newspaper articles). This article summarises the experience of the FAO Data Lab and how it has been useful for the Organization to fulfil its mandate.
Influencing discussions and use of neuroadvancements: Perspectives of Canadian occupational therapists
Authors: Villamil Valentina , Djebrouni Manel , Wolbring Gregor
Published: August 2022

BACKGROUND: The early involvement of many actors including health professionals is identified in neuroethics and neurogovernance discussions as crucial in constructing conversations around awareness, reaction, and knowledge development pertaining to the ethical, legal, and societal consequences of neuroscientific or neurotechnological advancements (NA). Occupational Therapists (OTs) have a stake in NA; however, OTs are rarely mentioned within this context. Lifelong learning (LL) could be used to increase OTs knowledge on NA and its consequences. However, LL is rarely mentioned within neuroethics and neurogovernance discussions. OBJECTIVE: The study’s purpose is to understand the role of OTs as professionals and citizens in neuroethics and neurogovernance discussions and to examine the utility of LL processes put in place for OTs to empower OTs to contribute in a meaningful way to NA discussions. METHODS: 8 semi-structured interviews with OTs were conducted and analyzed using a directed content analysis. RESULTS: Although participants believed OTs can provide a holistic perspective to neurogovernance discussions, their knowledge on NA and its consequences is limited, and LL is not used as a tool to remain informed about such consequences. CONCLUSION: More education on NA and its consequences throughout their OT degree and through LL opportunities is warranted to facilitate their involvement.
Psychosocial work environment and health when entering or leaving a managerial position
Authors: Lundqvist Daniel
Published: August 2022

BACKGROUND: Recruiting and retaining managers has become increasingly difficult in recent years, primarily because of a pressured work situation. A better understanding of managers’ work situation is required, and of the support they need. OBJECTIVE: The purpose of the study is to increase the understanding of managers’ psychosocial work environment and health by investigating individuals as they enter or leave a managerial position. METHODS: Longitudinal questionnaire data from 1971 individuals distributed across four groups were used: individuals who 1) entered or 2) left a managerial position between measuring points, and those who remained employed as 3) managers or 4) non-managers at both measuring points. RESULTS: Demands increased between the measuring points for those who entered a managerial position. Their resources and health were, however, rated higher than non-managers already before the transition. Demands decreased for those who left a managerial position, while their resources remained higher than non-managers. Health did not change by changing position. CONCLUSION: This study contributes to knowledge of what happens when someone enters or leaves a managerial position and increases the understanding of differences between managers and non-managers. Organizations should develop supportive strategies through talent management programs to help build resources in employees and future managers. Support should also aim to reduce the increased level of demands in newly hired managers.

Development of multiscale porous elastomer substrates with passive-cooling capabilities and strain-insensitive conductive nanocomposites for skin-interfaced electronics
Authors:   , Fei Qihui
Published: August 2022

[EMBARGOED UNTIL AUGUST 2023] Emerging skin-interfaced electronics have been playing a significant role in many areas such as clinical healthcare and mobile fitness tracking because they can collect a variety of biological signals from human body. However, conventional electronic materials are usually rigid and brittle, which leads to mechanical mismatch with soft human skin. To overcome the disadvantages, we paid attention to intrinsically stretchable polymer materials. This work focuses on the synthesis of novel multifunctional porous materials for breathable and intrinsically stretchable skin-interfaced electronics with minimal inflammation risks, outstanding mechanical pliability, and other desired features. We first report on the fabrication of multiscale porous elastomer supporting substrates with passive cooling properties which means the on-skin electronics made with the porous elastomer substrates can passively cool human bodies without energy consumption. It also exhibits other desired properties, including mechanical compliance, high breathability and waterproofing. The outstanding passive-cooling capability and breathability stem from the structural engineering of multiscale porous structure in elastomer, which was achieved by simple, cost-effective, and scalable phase separation-controlled process. We also demonstrate some applications of wearable skin-interfaced bioelectronics for continuous monitoring of human vital signals and human-machine interactions. These devices are patterned by spray printing of silver nanowires on prestretched multiscale porous polystyreneblock-poly(ethylene-ran-butylene)-block-polystyrene (SEBS) substrates. Leveraging the same versatile synthesis approach, we then introduce the synthesis of strain-insensitive conductive nanocomposite, which is enabled by well-controlled in-situ distribution of conductive nanofiller (i.e., silver nanowires) on the surface of microscale pores. The judiciously engineered structure enables substantially decreased (~50 times) percolation threshold and excellent strain-insensitivity property. The obtained porous conductive nanocomposite also exhibits outstanding breathability, conductivity, strain-insensitivity, mechanical and electrical robustness and durability.
Remodeling the narrative of women and the built environment in the Middle Ages
Authors:   , Jacobs Alicia Gabrielle
Published: August 2022

Scholarship on the design, construction, decoration, and reception of the built environment during the medieval era has tended to focus on men as the primary makers and default users of this environment. However, recent scholars have examined a variety of media -- including art, architecture, and texts -- and uncovered the many contributions that medieval women made to these fields. By examining feminist scholarship and historiography, this thesis explores three case studies -- elite and non-elite medieval women within male-dominated design spaces, Eleanor of Castile and her acquisition of property, and Christine de Pizan's manipulation of an architectural trope -- through a feminist lens to highlight the various ways in which medieval women worked in gendered environments, and carved out space and claimed agency through their contributions to the design world in the Middle Ages. These case studies include physical structures that were created as a result of inherited or acquired wealth, idealized spaces that were designed to protect women against the vicious attacks of men, and explores conditional situations in which both elite and non-elite women worked in the built environment. This thesis recognizes the struggles that these women endured in order to create space for themselves within societal confines, and contributes to and expands the scholarship surrounding the multifaceted ways in which women contributed to the design world in the Middle Ages. These women cleverly maneuvered through gendered spaces; capitalized on their elite roles in their households; acquired and managed property; and manipulated tropes and disseminated knowledge during a time rife with patriarchal norms.
Taxonomy, taphonomy, and ecology of Silurian (late Telychian) conulariids from the Waukesha Lagerstatte, Wisconsin
Authors:   , Miller April
Published: August 2022

The Silurian (late Telychian Stage) Brandon Bridge Formation, Wisconsin, USA, hosts a diverse biota including arthropods, annelids, graptolites, brachiopods, corals, sponges, and algae, some of which exhibit exceptional soft-bodied preservation. Whilst many of the rarer, enigmatic constituents of the Waukesha Konservat-Lagerstatte have received taxonomic and taphonomic study, some of the more common species remain poorly documented. In order to provide a more complete account of the ecology and diversity of the assemblage, this study is focused on the description of a prolific Waukesha faunal element--the conulariids. The aims of the thesis are three-fold. Firstly, we provide a systematic description of the two conulariid species known from the Waukesha Lagerstatte. Secondly, we assess the general taphonomy and preservational pathways of the conulariids. Thirdly, we investigate the identity of, and paleoecological relationship between the conulariids and their epibionts. Specimens (n = 40) borrowed from the University of Wisconsin Geology Museum, Madison, USA were examined using a combination of light microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy (SEM-EDS), to assist in the classification of these taxa. There are two distinct species from this assemblage: Conularia niagarensis Hall, 1852 and Metaconularia cf. manni (Roy, 1935). EDS data shows that the conulariid test is composed of secondary francolite (calcium phosphate); we infer that these originally biomineralized organisms were exposed to post-burial demineralization from shifting pH conditions, resulting in their uncommon two-dimensional preservation, before later taphonomic or diagenetic replacement via francolite. Holdfast scars present on the conulariid test offer a unique glimpse into the paleoecology of this Silurian benthic assemblage. The holdfast morphology bears a close resemblance to that of the epibiont Sphenothallus which is also present in the Waukesha Biota. Statistical analysis of holdfast size and distribution on the conulariid test gives insight to the nature of their symbiotic relationship. Our results did not find any significant support for a parasitic relationship. However, commensalism cannot be ruled out and serves as an alternative explanation for the relationship between these two organisms.
Evaluating the effects of choice across varying levels of preferred items
Authors:   , Whitaker Emily Jo
Published: August 2022

The current study compared the differential effects of choice and no-choice conditions on skill acquisition, when provided as a consequence and when choice conditions involved the opportunity to choose from an array of items of varying levels of preference (high, moderate, and low preference). These effects were evaluated across four conditions: top preference choice, varying-level preference choice, no choice, and control. Additionally, the current study evaluated children's preferences for choicemaking opportunities among three children with autism spectrum disorder. Results indicated that the top preference choice condition increased treatment efficacy for two of the three participants, and two of the three participants demonstrated preference for choice-making opportunities
Homeless not hopeless: understanding how graduate students who experience homelessness and housing insecurity successfully navigate their education
Authors:   , Lane-Bonds Dena
Published: August 2022

Obtaining a college degree and, even more so, a graduate degree is a critical component of many people's American dream. For some completing a graduate degree is a milestone of success. However, due to rising tuition and housing costs, as well as other compounding factors such as food insecurity, for many, this dream may be deferred. According to the National Center for Homeless Education (2017), for the 2016-2017 academic year, more than 30,000 college students reported on their Free Application for Federal Student Aid that they experienced homelessness or housing insecurity. Like this grim statistic, much of the current discourse on homelessness and housing insecurity in higher education is deficit-centered. Focusing on such deficits overlooks the experiences of students who face challenges yet persist. Despite the mounting fiscal pressures and the fact that housing insecurity and homelessness can present extreme barriers to college completion, there are students whose stories portray a different narrative. To challenge deficit thinking, this study employed Harper's (2010) anti-deficit achievement framework to understand how students, specifically graduate students who experience homelessness or housing insecurity, successfully navigate their educational journey. It also explored what academic interactions and experiential opportunities with peers and institutional agents contribute to their persistence and academic achievement. I used narrative inquiry to gather the stories of five graduate students either currently or recently enrolled at a large Midwest land-grant public research-intensive university. Findings indicated that for these graduate students (1) hope; (2) family; (3) friends; (4) determination; (5) institutional agents; (6) a desire to give back to their communities; (7) campus and community resources; (8) and faith all contributed to participants success in simultaneously navigating their graduate journey and their experiences with homelessness and housing insecurity.
Understanding the influence of a contextual factor, stigma consciousness: a barrier for underrepresented students in engineering
Authors:   , Lee Bo Hyun
Published: August 2022

The present study used Social Cognitive Career Theory (SCCT; Lent, Brown, & Hackett, 1994) to examine the influence of racial/ethnic stigma consciousness on persistence intention among 263 underrepresented racial/ethnic minority engineering students. Path analysis was used to test a model depicting relationships between contextual (i.e., racial/ethnic stigma consciousness, institution types) and person-cognitive (i.e., self-efficacy, positive and negative outcome expectations, persistence intention) variables as hypothesized in SCCT. Results indicated that both hypothesized indirect and direct structural models provided an excellent fit to the data, but the hypothesized indirect model showed better fit. Test of mediation was statistically significant for engineering self-efficacy, but not for positive and negative outcome expectations in the relations between racial/ethnic stigma consciousness and persistence intentions. Results of moderated mediation indicated a significant interaction of coping efficacy on racial/ethnic stigma consciousness on the indirect effect via engineering self-efficacy. A series of ANOVA and MANOVA were also conducted to determine whether demographic and contextual variables could explain racial/ethnic stigma consciousness, coping efficacy, and socio-cognitive variables (i.e., self-efficacy, positive and negative outcome expectations, persistence intentions) to pursue engineering degree. Suggestions for future research directions, clinical implications, and limitations are further provided.
Reverse knowledge absorptive capacity of MNE-HQ (RKAC): conceptualization, theoretical framework, and empirical testing
Authors:   , Chen Yiwen
Published: August 2022

Despite the increasing importance of reverse knowledge for innovation and competitive advantage of multinational enterprises (MNEs), the issue of how to make reverse knowledge transfer (RKT) more effective is under-explored. Specifically, what constitutes the absorptive capacity of MNEs' headquarters (HQ), the receiver of reverse knowledge, remains conceptually vague and empirically inconsistent. This study develops a broad conceptualization of MNE-HQs' reverse knowledge absorptive capacity--the RKAC--that integrates two major perspectives, namely motivation-ability view, and process-based view of absorptive capacity. Departing from previous studies that treat absorptive capacity as a generic construct, the broad construct of RKAC is developed for each specific HQ-subsidiary dyad. This study also proposes a theoretical framework that accounts for the antecedents, outcomes, and boundary conditions of RKAC. The proposed model was empirically tested with survey data collected from 206 executive mangers of subsidiaries operating in China. The results supported the theoretical conceptualization and the majority of the proposed hypotheses.
The material politics of ivory in early modern Europe
Authors:   , Grimes Kaitlin Rae
Published: August 2022

This dissertation sets out to challenge the material history and biography of ivory in early modern Europe (ca. 1600-1800) and explores the mutable materialities of ivory as both a sculptural material and a vehicle of cultural meaning. As an often-peripheral material, ivory's history needs to be reimagined as a central and integral material player on the early modern European artistic stage. Throughout my dissertation, I upend the normative paradigms surrounding ivory to re-contextualize and reconceptualize the material as a performative mechanism of meaning for an object rather than as material used to create an object. This dissertation focuses on four main geographic areas of early modern Europe -- the Austrian Habsburg Empire, the Kingdom of Denmark-Norway, the Electorate of Saxony, and the British Empire -- as an illustration of ivory's material power and also as an elucidation of non-dominant topographical spaces as centers of material artistic prowess. I explore mythological and religious sculptures, political portraits, ivory frigates, and ivory furniture to answer the question of "why ivory?" What made this African material so desirable for European commissioners? What intrinsic cultural, iconographic, and semiotic value did this natural material hold for elite European society? As I argue, ivory's intrinsic religious, mythological, political, and colonial materialities fashioned a material representative of the changing cultural ideologies of early modern Europe. Through the explication of specified narratives, ivory's agency and material potency shines as bright as its own polished surface.
Propagation of regional seismic phases (Sn and Lg) in the Middle East and East Asia
Authors:   , Hui Hongjun
Published: August 2022

I have studied the propagation of the regional seismic waves (Sn and Lg) in the Middle East (ME) and East Asia. The methods used in this study are : (1) the reverse two-station method (RTM) to determine the attenuation and site response, (2) the logistic regression/Bayesian lasso method to predict the probability of observing Sn and (3) the LSQR method to generate attenuation and predicted probability tomography. I have constructed new frequency-dependent Lg and Sn attenuation models in China. The results show high Lg Qs in SE and NE China and the Tarim basin, while low Lg Qs are found in the Tibetan plateau. High Sn Qs are found in the Sichuan basin and the Ordos and Tibetan plateaus. Low Sn Qs are found in eastern China and northern, eastern Tibetan plateau. I have also estimated the site response with both Lg and Sn in China. With the differential site response results, I found that the effective Sn attenuation may include the effect of the crustal legs, which is supposed to be eliminated in RTM. I have also constructed a model that shows the spatial variability in Sn propagation in the ME and East Asia. The model has successfully predicted the probability of observing Sn as well as being blocked. We observe high probabilities of observing Sn in stable and oceanic regions, such as the Arabian Plate, the Mediterranean Sea. In tectonically active areas, such as the Tibetan and Iranian plateaus, I have observed a low probability of observing Sn propagation. These models should help determine where existing attenuation models are significantly biased by systematic data censorship.
Using communicative patterns to predict Twitter users' social capital, likability, and popularity gains with natural language processing
Authors:   , Hu Lingshu
Published: August 2022

Social media constructs a computer-mediated public space where individuals' visibility and influence can be quantitatively measured by the number of likes, retweets, and followers they receive. These metrics serve as a reward system that not only reflects users' popularity and social capital but also influences the climate of public opinion and deliberative democracy by encouraging and discouraging certain types of communication. Through analyzing Twitter data collected from U.S. congressional politicians and ordinary U.S. Twitter users in seven/eight waves, this study explores how communicative patterns--dual-process styles and sentiment--predict users' social capital, likability, and popularity gains on Twitter as well as how political identity and intergroup communication moderate the relationships between these variables. It found that: (a) rational expressions increase social capital and popularity gains while emotional expressions increase likability gains; (b) positive expressions generate a curvilinear effect on social capital, likability, and popularity gains in the politician dataset; (c) compared with Democratic users, Republican users receive relatively more social capital, likability, and popularity gains from emotional and negative expressions than from rational and positive expressions; (d) rational expressions lead to relatively more likability and popularity gains than emotional expressions in a group-salient context; and (e) positive expressions in ingroup/outgroup conversations generate opposite effects in the politician and ordinary user datasets. In addition, this study develops and advances computational methods in detecting communicative patterns, political identities, and intergroup communication. By implementing Distributed Dictionary Representations, this study creates metrics to measure dual-process thinking styles and sentiment in text; by developing a two-step model with deep learning using an attention mechanism, this study creates an interpretable method to detect political partisanship and intergroup communication.
