Authors: Thitart Phitphisut , Hotrawaisaya Chattrarat
Published: July 2023

The objectives of this article are 1) to develop a model of a business performance improvement of road transport enterprises in the Eastern Economic Corridor (EEC) of Thailand, and 2) to study the impacts of innovation, green logistics, and sustainable organizational development on business performance of road transport enterprises in the EEC. The population of the study was all 4,318 road transport enterprises in Thailand’s EEC. The stratified random sampling method was used and a sample size larger than 20 times the number of observed variables was selected. Questionnaires were distributed to a sample of 336 enterprises. The questionnaire’s relevance and reliability were assessed using an Index of Item Objective Congruency (IOC) and Cronbach’s alpha coefficient. A statistical software was used to analyze the collected data, using Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM).

Results showed that the model fitted well with empirical data. All of these factors positively correlated. Factors that had the highest direct, positive effect on business performance of road transport enterprises were innovation, followed by green logistics and sustainable organizational development. Moreover, it was found that innovation and green logistics indirectly and positively affected the performance of road transport enterprises. The data suggested that road transport enterprises in the EEC should consider and implement innovations relevant to their business. Moreover, there is a need to move towards environmentally friendly logistics, to sustainably develop the business, improving the performance, and increase their competitiveness.

Research On The Coupling and Coordination between Green Investment and Marine Economic Development Level
Authors: Guo Ziyu
Published: July 2023

In this paper, I use the entropy value method to measure the development level of marine economy of 11 coastal provinces in China from 2007 to 2017. Then use the total investment in environmental pollution control, the completed investment in forestry, and the total investment in urban environmental infrastructure construction to measure the level of regional green investment, and establish a coupled coordination degree model to evaluate the coupling and coordination level between green investment and marine economy on the 11 coastal provinces from 2017 to 2017 (due to data availability). The conclusion shows that from 2007 to 2017, the value of green investment and the level of marine economy both shew an upward trend, and the average annual growth rate of green investment is higher than the level of marine economy, but marine economy grew more stable and performed better on regional balance. The coupling coordination degree between green investment and marine economy shew a change from serious disorder to good coordination from 2007 to 2017.

Published: July 2023

The charge transfer properties of organic molecular semiconductors are closely related to the accumulation of molecular crystals. Based on quantum nuclear tunneling model, the effect of polymorphs on the charge transport properties of binary charge-transfer complexes composed of perylene and 4,8-bis(dicyandiylidene)-4,8- dihydrobenzo[1,2-b:4,5-b']-dithiophene (DTTCNQ). Analysis of the reorganization energy of molecular crystals using the four-point (4P) method. Perylene was analyzed using the normal mode (NM) method, and the middle frequency around 1500 cm-1 made the largest contribution to the reorganization energy, followed by the low frequency in the neighborhood of 500 cm-1. In the α-phase crystal, the maximum anisotropic mobility of the hole and electron are in the xy and xz directions, respectively, and those in the β-phase crystal are in the xy and yz directions, and anisotropic mobility are closely related to the transfer integrals. The α-phase crystal is more stable than the β-phase as a ambipolar material. The polymorphism of perylene-DTTCNQ crystals gives rise to different molecular stacking in the α- and β-phases, resulting in a large difference in the charge transport properties of the α- and β-phases.

Published: July 2023

Estimating the carbon stocked in planted forests is important to assess the mitigation effect and to predict potential impact of mechanisms to reduce carbon emissions. This study was conducted in Central Research Institute for Dryland Agriculture, Hyderabad to develop the allometric equations for predicting the above and below ground biomass and total carbon in three different basal diameter classes (0-10 cm, 10-20 cm and 20-30 cm) of Simarouba glauca DC. Higher total biomass of 169.0 kg/tree in 20-30 diameter class followed by 10-20 cm (57.81 kg/tree) diameter class were recorded in S. glauca. From the findings, above ground biomass has a highly significant relationship with tree height, basal diameter, DBH, crown height, crown width. There was a significant linear relationship between below ground biomass and predictors, viz. tree height (0.803), basal diameter (0.820), DBH (0.810), crown height (0.985) and crown width (0.957). And also, strong non-linear relationship (0.985) exists between total biomass and crown height (0.985) followed by crown width (0.957). The allometric coefficients which were calculated from the allometric relations between the biomass of various tree components on total carbon for S. glauca. The highest and strong allometric coefficient registered between total carbon and crown height (0.992) followed by crown width (0.978). This finding may be first for S. glauca in India as no significant literature is available for estimation of biomass and carbon in different components of the species. So the result of this study will be helpful in predicting the amount of carbon credits earned by plantations on area basis, which are requisite under the Kyoto Protocol and REDD policy.

Health and Inequity: A Socio-Cultural Analysis on Food and Nutrition Among Students
Authors: Pathan Ziya A.
Published: July 2023

Food is not just a biological need but it is very much social in nature. Socialization and culture has an influence on the eating habits as culture plays a significant role in our daily food choices and diet. The present study endeavors to create an awareness on the effects of unhealthy food habits which are developed by the students due to one’s culture or enforced by an organization. Undergraduate students pursuing education at University of Eswatini are considered ensuring or seeking information that will be helpful in the research. Nutritionist in the academic sphere is consulted to interpret the data looking into the health perspective and predict the threats imposed by the food culture health-wise. The study revealed that most students eat twice a day and some once which is not advisable and recommended by dietitians and nutritionists, because this can obviously lead to malnutrition and under nourishment. The developed culture of eating in the institution, happens to impose an unhealthy hazard to the health of students. One of the major challenges of students is that they are not permitted to cook for themselves in the institution (dormitory), which exposes students to junk food, hence the future health complications, like obesity, diabetes, cardiovascular diseases and many other diet related illnesses or conditions. The research recommends reframing university rules on cooking, provision of meals on fixed time and nutrition based education should be provided by the institution.

Authors: Altaey Omar Younis , Alhaaik Ammar Ghamin
Published: July 2023

The present study aims to elucidate retinal development by analyzing the histomorphological and histomorphometrical parameters in white rabbits (Oryctolagus cuniculus retina). Samples were collected from 25 rabbits divided into five different age groups: 1, 10, 15, 30, and 40 postnatal days (PND). The samples were then sectioned, processed, and stained with Hematoxylin and Eosin stain, as well as Masson's trichrome stain. Some sections were additionally stained with toluidine blue (TB) stain to detect cell density in the outer and inner nuclear layers. Measurements of retinal layers were performed for morphometric comparison among the age groups. The findings revealed that the total thickness of the retina gradually decreased with age. The thickness of the inner and outer nuclear layers, as well as cellular density, also decreased with the development of the photoreceptor layer (rods and cones). This decrement was accompanied by an elevation of the outer plexiform layer thickness and swelling of the ganglion cell layer, particularly after the opening of the eyelids and the differentiation of the different layers of the retina. The histomorphometry results in the retina showed significant differences in the thickness of its different layers among the five age groups. In conclusion, Retina showed highly active histological development and growth with cellular differentiation and significant measurements differences before and after eyelid opening between 10 -15 PNDs.

Psicanálise, uma ciência Unheimliche
Authors: Paim Filho Ignácio Alves
Published: July 2023

O presente trabalho tem como proposta refletir sobre a inter-relação da psicanálise com a neuropsicanálise. Para viabilizar tal meta, tomará como ponto de partida o pensar do neurocientista Eric Kandel sobre essa temática. No decorrer de suas especulações, o autor transita por duas vertentes: de um lado, levanta interrogações sobre as neurociências – entre elas, a importância do postulado fundante da psicanálise, a saber, o inconsciente; e, por outro, propõe o quanto é imprescindível que os psicanalistas cultivem o seu compromisso de manter a singularidade da sua ciência, calcada no princípio da incerteza – um conhecer e um não conhecer decorrentes das ramificações e derivativos das inscrições pulsionais do inconsciente, que o revelam e o encobrem.

O desvalimento do povo cambojano a partir de uma experiência emocional e sua relação com a psicossomática
Authors: Katz Gildo
Published: July 2023

A partir de uma experiência com um guia cambojano, examino, à luz da teoria do desvalimento, o efeito do genocídio ocorrido naquele país com a ascensão de um líder despótico. Sustento que a perda da subjetividade do povo cambojano acarretou, além do assassinato em massa, graves efeitos emocionais e corporais não só nos indivíduos em particular, mas no povo em geral. Finalizo, como corroboração desses fatos, o efeito positivo do vínculo empático que se estabeleceu entre o guia e o autor.

Sobre as primeiras inscrições
Authors: Casas de Pereda Myrta
Published: July 2023

O trabalho propõe uma perspectiva dinâmica, onde a substituição e a transformação do fantasma sintomático reorganiza as articulações patogênicas das marcas mnêmicas inconscientes. Ao enfoque da repetição sintomática se opõe a escuta analítica que, propiciada pela recriação e atualização transferencial, permite que o objeto (para o outro a quem é dirigida a pulsão) ofereça um perfil diferente. A interpretação psicanalítica conduz o mais próximo possível das coordenadas de prazer-desprazer que rodearam a inscrição psíquica. Através de um exemplo clínico da análise de uma criança de seis anos, reflete-se sobre a dimensão estruturadora das primeiras marcas (sempre inferidas), seus efeitos e destinos na estruturação psíquica e sua escuta a partir dos efeitos transferenciais no processo analítico. Desde uma socialização altamente dificultada por severos transtornos de conduta, o espaço transferencial (como resposta espontânea e não programada do analista) privilegia a demanda de amor em um forte discurso persecutório que desarticula, uma e outra vez, o circuito paranóico. Também a utilização do humor e a imposição de limites de forma serena e libidinal permitiram uma singular inflexão da sintomatologia nos primeiros anos da análise.

Published: July 2023

Partindo de uma revisão dos conceitos de imaginação, fantasia e jogo na filosofia e em Freud, Klein, Winnicott, Meltzer, Bion, Segal e Castoriadis, a autora diferencia o caráter mais defensivo, fechado, e o estado de certeza da fantasia com o caráter aberto da imaginação, que se une à conjetura e à exploração do mundo em diferentes possibilidades. Relaciona o clímax do jogo e da ação da imaginação com o apogeu do complexo edípico. Aponta que na psicose haveria uma hipertrofia da fantasia e uma incapacidade para imaginar.

Authors: Nascimento Mônica de Nazaré Corrêa Ferreira , Marques Carla Suzana da Encarnação , Rego Maria da Conceição Peixe
Published: July 2023

O microcrédito ficou conhecido, mundialmente, como instrumento de combate à pobreza, especialmente entre as mulheres empreendedoras. Este artigo tem por objetivo analisar algumas experiências de microcrédito e empreendedorismo feminino em diferentes contextos socioterritoriais, com a finalidade de analisar como as mulheres experimentam o microcrédito em suas vidas. Os artigos foram obtidos da consulta a duas bases de dados reconhecidas internacionalmente: Scopus e Web of Science. Constatou-se que quanto maior a pobreza do país, menos eficaz é a política de microcrédito para melhorar as condições de vida das mulheres empreendedoras. A autonomia na tomada de decisões, o apoio da família, boas habilidades no desenvolvimento de redes, acesso a treinamento, conhecimento de mercado e adequação dos modelos de microcrédito às necessidades dos negócio das mulheres empreendedoras contribuem para o sucesso empresarial e, por conseguinte, para a eficácia do microcrédito. Como proposição para estudos futuros, sugeriu-se desenvolver mais pesquisas com a utilização da abordagem qualitativa, no contexto de países em desenvolvimento.

Published: July 2023

The thriving of Internet‐of‐Things and integrated wireless sensor networks has brought an unprecedented demand for sustainable micro‐Watt‐scale power supplies. Development of high‐performing micro‐thermoelectric generator (μ‐TEG) that can convert waste thermal energy into electricity and provide sustainable micro‐Watt‐scale power is therefore extremely timely and important. Herein, a significant advance in the development of earth‐abundant, nontoxic thermoelectric materials of aluminum‐doped zinc oxide (AZO) is presented. Through nanostructure engineering using a novel in situ O2 plasma treatment, AZO films are demonstrated with ultralow thermal conductivity of 0.16 W m−1 K−1 which is the lowest reported in the literature. This nanostructured film yields a power factor of 294 μW m−1 K−2 at 563 K and has resulted in a state‐of‐the‐art ZT of 0.11 at room temperature and 0.72 at 563 K for AZO thin films. Furthermore, the fabrication and testing of a prototype lateral μ‐TEG are reported based on the AZO thin film which achieves a power output of 1.08 nW with an applied temperature difference of 16.9 °C.

Research on neural processes with multiple latent variables
Authors: Yu Xiao‐Han , Mao Shao‐Chen , Wang Lei , Lu Shi‐Jie , Yu Kun
Published: July 2023

Neural Process (NP) fully combines the advantages of neural network and Gaussian Process (GP) to provide an efficient method for solving regression problems. Nonetheless, limited by the dimensionality of the latent variable, NP has difficulty fitting the observed data completely and predicting the targets perfectly. To remedy these drawbacks, the authors propose a concise and effective improvement of the latent path of NP, which the authors term Multi‐Latent Variables Neural Process (MLNP). MLNP samples multiple latent variables and integrates the representations corresponding to the latent variables in the decoder with adaptive weights. MLNP inherits the desirable property of linear computation scales of NP and learns the approximate distribution over objective functions from contexts more flexibly and accurately. By applying MLNP to 1‐D regression, real‐world image completion, which can be seen as a 2‐D regression task, the authors demonstrate its significant improvement in the accuracy of prediction and contexts fitting capability compared with NP. Through ablation experiments, the authors also verify that the number of latent variables has a great impact on the prediction accuracy and fitting capability of MLNP. Moreover, the authors also analyze the roles played by different latent variables in reconstructing images.
Coordination of time delay and GCSC for frequency stabilization of dual‐area interlinked microgrid using non‐integer controller optimization
Authors: Latif Abdul , Hussain S. M. Suhail , Iqbal Atif , Das Dulal Chandra , Ustun Taha Selim , Al‐Durra Ahmed
Published: July 2023

This study presents a novel frequency regulation solution for renewables (wind‐solar tower)‐bio (biodiesel‐biogas) cogenerated independent dual‐area interlinked microgrid power system (IµPS) with collective effect of time delay and flexible gate‐controlled series capacitor (GCSC). As a component, a non‐integer proportional fractional integral fractional derivative (PFIFD) controller is introduced whose dynamic responses is compared with integer order PID (IOPID) and fractional order PI (FOPI) controllers. The findings demonstrate that the suggested non‐integer PFIFD controller performs better than IOPID and FOPI at giving superior dynamic properties, such as different decision parameters and minimum error function (J). Subsequently, to obtain the optimally tuned controllers’ parameters, a recently developed yellow saddle goatfish technique (YSGA) is leveraged. In this study, the comparative effect of time delay, interline power flow controller (IPFC) and GCSC scheme have been analyzed under real time wind data in IµPS. Further, a meticulous sensitivity assessment of YSGA tuned PFIFD controller is performed under different uncertainties. The improved results show that the recommended YSGA‐based PFIFD controller offers a wonderful improvement in system frequency stability under a variety of situations, including system uncertainties, physical constraints, and significant renewables penetration. Finally, real‐time hardware‐in‐the‐loop (HIL) simulation platform is utilized to validate the proposed control approach.
Position-Specific Enrichment Ratio Matrix scores predict antibody variant properties from deep sequencing data
Authors: Smith Matthew D , Case Marshall A , Makowski Emily K , Tessier Peter M
Published: July 2023

Motivation

Deep sequencing of antibody and related protein libraries after phage or yeast-surface display sorting is widely used to identify variants with increased affinity, specificity, and/or improvements in key biophysical properties. Conventional approaches for identifying optimal variants typically use the frequencies of observation in enriched libraries or the corresponding enrichment ratios. However, these approaches disregard the vast majority of deep sequencing data and often fail to identify the best variants in the libraries.

Results

Here, we present a method, Position-Specific Enrichment Ratio Matrix (PSERM) scoring, that uses entire deep sequencing datasets from pre- and post-selections to score each observed protein variant. The PSERM scores are the sum of the site-specific enrichment ratios observed at each mutated position. We find that PSERM scores are much more reproducible and correlate more strongly with experimentally measured properties than frequencies or enrichment ratios, including for multiple antibody properties (affinity and non-specific binding) for a clinical-stage antibody (emibetuzumab). We expect that this method will be broadly applicable to diverse protein engineering campaigns.

Availability and implementation

All deep sequencing datasets and code to perform the analyses presented within are available via https://github.com/Tessier-Lab-UMich/PSERM_paper.
Prevalence of suicide risk among a national sample of individuals referred from a primary care subpopulation, 2017–2020
Authors: Little Virna , Gatanaga Ohshue S , Hutchins Spencer , Gloria Christian T
Published: July 2023

Over the past decade, the age-adjusted suicide rate has increased by 35.2% in the United States. In primary care, practitioners often interact with patients at risk of dying by suicide, yet little is known about the prevalence of suicide risk in primary care populations. Patient data from 2017–2020, consisting of a national sample of patients referred from primary care and enrolled in collaborative care behavioral health services (n = 37 666), were analyzed. Controlling for demographic characteristics, logistic models were used to compare suicide risk prevalence by behavioral health diagnosis. An estimated 9.96% (95% confidence interval [CI]: 9.65–10.27)—or approximately 3751 individuals—of the total sample screened positively for suicide risk. Compared with individuals diagnosed with generalized anxiety disorder, individuals diagnosed with bipolar disorder had 8.21 times the odds (95% CI: 6.66–10.10) of screening for suicide risk. Practitioners and health care systems may benefit from adding suicide risk screeners as a standard practice for referred patients, which may lead to further development of clinical pathways and provider training. The high rate of suicide risk across the sample suggests that more research is needed to understand suicide risk prevalence across primary care and collaborative care populations.
Exosomes, the Key Players in Cell-To-Cell Communication as the Universal Nano-Sized Disease Sensors of the Future
Authors: Mohammadi Kyana , Badilescu Simona , Ghosh Anirban , Packirisamy Muthukumaran
Published: July 2023

Exosomes are nanovesicles shed by cells into the extracellular space. From an engineering point of view, exosomes can be assimilated to a complex system, that is, an arrangement of parts that together exhibit a behavior that the individual constituents do not. The authors argue that the unique composition of exosomes as well as their involvement in cell-to-cell communication and monitoring a multitude of diseases, justify entirely looking at exosomes, in the future, as universal sensors of diseases. In this paper, after the short background information on exosomes, the authors show how they are involved in the progress of different diseases.
Clandestine Dumpsites and Crime in Mexico City: Revisiting the Broken Windows Theory
Authors: Massa Ricardo , Fondevila Gustavo , Gutiérrez-Meave Raúl , Bonilla Alguera Gerardo
Published: July 2023

This paper revisits the broken windows theory with a particular focus on one sign of social disorder: clandestine dumpsites. To explore whether these are predictors of different types of crimes at a neighborhood level, two classification methods were used. Results suggest that clandestine dumpsites have a high predictive capacity for the crimes of dispossession, property damage, house robbery, vehicle theft, and robbery, and have almost none for environmental crimes or robberies of businesses. It is suggested that clandestine dumpsites should be the object of a comprehensive public policy that, in addition to reducing or eliminating the associated health and environmental risks, seeks to reconstitute the social fabric and motivates the long-term recovery of the public space.

A cross-sectional study was conducted among 1061 female migrant workers aged 18 to 29 from January to November 2020 in Hanoi, Vietnam. Anonymous interview questionnaires were used to collect data on demographic characteristics, psychosocial wellbeing (PWB), sexual self-efficacy, and depressive symptoms. Mediation analysis was conducted to explore the mediation effect of sexual self-efficacy on the relationship between PWB and depressive symptoms.

Results:

Nearly 8% of the female migrant workers reported experiencing depressive symptoms. The final mediation model showed that the effect of overall psychological wellbeing on depressive symptoms was partially mediated by sexual self-efficacy. Specifically, 4.1% of the effect of overall PWB on depressive symptoms was mediated through sexual self-efficacy. In the PWB subdimension analyses, sexual self-efficacy mediated 14.3% of the effect of personal growth, 8.8% of the effect of purpose in life, 8.0% of the effect of autonomy, and 7.8% of the effect of environmental mastery on depressive symptoms, respectively.

Conclusion:

The study findings demonstrate that sexual self-efficacy plays an important role in the relationship between psychosocial wellbeing and depressive symptoms among female migrant workers in industrial zones in Vietnam. Improving psychosocial wellbeing and promoting sexual health including sexual self-efficacy should be prioritized when addressing depressive symptoms and mental health concerns among industrial zone female migrant workers in Vietnam, which may also be applicable in other low- and middle-income countries with similar socio-cultural settings.

Background:

A patient’s pathway to care is often characterized by a sequence of actions taken to remedy ill-health. Research exploring the help-seeking behavior of individuals with mental health problems in sub-Saharan Africa is relatively limited. This study assessed the perceptions and experiences of mental illness and treatment among patients with mental illness at two psychiatric facilities in Johannesburg, South Africa.

Methods:

309 interviewer administered surveys were conducted between January and July 2022. We used a logistic regression model to examine factors associated with receiving treatment for mental illnesses from traditional healers. Semi-structured interviews were conducted with 18 participants during the same period. Interviews were transcribed and translated into English. Data were managed using NVivo 11 software and thematically analyzed.

Findings:

Results showed that 144 (47%) patients sought mental health care from traditional healers. Higher anxiety symptoms, number of people in the household, believing that traditional medicine can cure mental illnesses, and township living were associated with seeking mental healthcare from traditional healers. Qualitative analysis indicated that participants often believed that mental illness was due to bewitchment and consulted with multiple traditional healers, thus spending large amounts of money for treatment and ultimately delaying access to biomedical care.

Conclusion:

Collaborative approaches between traditional healers and biomedical professionals show promise in terms of allowing for improved identification and treatment of individuals with mental disorders.

Background:

Mental health (MH) disorders are major causes of disability in Guatemala. Unfortunately, limited academic training and funding resources make MH care inaccessible to most people in rural Guatemala. These disparities leave many indigenous populations without care. Project ECHO™ is an educational model used globally to deliver virtual training for providers in rural/ underserved communities. The aim of this project was to implement and evaluate a Project ECHO™ program bridging MH training gaps for providers who serve rural communities in Guatemala.

Methods:

The Project ECHO™ curriculum was implemented through a partnership between educational and nonprofit institutions in Guatemala City and the United States. Participants were primary care physicians and nurses working in rural Guatemala as well as medical/nursing/psychology students. Evaluation of its implementation was guided by a RE-AIM framework. Reach, effectiveness, adoption, fidelity, sustainability, acceptability, feasibility, and appropriateness were evaluated using a mixed-methods approach, using a pre-post survey and semi-structured focus groups.

Results:

Forty unique participants attended the five sessions. Attitudes about mental health did not change quantitatively but self-efficacy improved in four of five modules. High quality fidelity scores were noted in two of five sessions. Sustainability scores across multiple domains were highly rated. Scores on instruments measuring acceptability, feasibility, and appropriateness were high. Focus groups showed two main themes: the curriculum filled a gap in education and further adaptation of the model might help improve the experience.

Conclusion:

Implementation of the Project ECHO™ educational model appeared to have good reach/adoption, showed improvements in self-efficacy, illuminated facilitators and barriers to sustainability, and was felt to be acceptable, feasible, and appropriate. Qualitative analysis supported these conclusions. Future directions would include ongoing evaluation and monitoring of further Project ECHO™ curricular experiences through this partnership and adaptation of this project to other learners and settings in Latin America.
The effect of heat-treatment temperature (HTT) on the carbon matrix development of both polyarylacetylene-and phenolic-derived carbon–Carbon (C/C) composites

Phenolic resins have been successfully used in the manufacture of C/C Composite hardware. However, they require costly, multiple impregnation–carbonization cycles due to their low char yield. Polyarylacetylene (PAA) resin is a promising alternative carbon precursor that possesses numerous advantages due to its higher char yield and low mass loss. In addition, both thermoset-derived carbons are non-graphitizable and rely on stress graphitization for matrix development, which ultimately dictates composite mechanical performance. The stress graphitization behavior of both composite systems was investigated and related to their mechanical behavior. PAA and phenolic-derived/T50 C/C composites were processed to a series of heat-treatment temperatures (HTTs), (1100°, 1800°, 2800°C) and compared. Increases in localized graphitization as verified by image analysis, AFM, and Raman were observed with increasing HT for both systems, though notably to a much higher degree for the phenolic system. We believe this to be a result of the larger degree of matrix pyrolysis shrinkage experienced at the fiber-matrix interface promoting molecular alignment. The mechanical properties of both composites were strongly affected by the HTT, primarily due to a weakening of the fiber-matrix interface. However, the phenolic-derived composite exhibited a 40% greater increase in fiber strength utilization over the PAA-derived composites after 2800°C, which is attributed to this highly oriented microstructure which contributes favorably to intra-matrix failure and crack deflection. Although there are benefits in utilizing high char yield carbon precursors that reduce manufacturing timelines, one must also account for possible differences in microstructure development when designing these composites for next generation systems.

Published: July 2023

Coordinated mineralization of soft tissue is central to organismal form and function, while dysregulated mineralization underlies several human pathologies. Oral epithelial–derived ameloblasts are polarized, secretory cells responsible for generating enamel, the most mineralized substance in the human body. Defects in ameloblast development result in enamel anomalies, including amelogenesis imperfecta. Identifying proteins critical in ameloblast development can provide insight into specific pathologies associated with enamel-related disorders or, more broadly, mechanisms of mineralization. Previous studies identified a role for MEMO1 in bone mineralization; however, whether MEMO1 functions in the generation of additional mineralized structures remains unknown. Here, we identify a critical role for MEMO1 in enamel mineralization. First, we show that Memo1 is expressed in ameloblasts and, second, that its conditional deletion from ameloblasts results in enamel defects, characterized by a decline in mineral density and tooth integrity. Histology revealed that the mineralization defects in Memo1 mutant ameloblasts correlated with a disruption in ameloblast morphology. Finally, molecular profiling of ameloblasts and their progenitors in Memo1 oral epithelial mutants revealed a disruption to cytoskeletal-associated genes and a reduction in late-stage ameloblast markers, relative to controls. Collectively, our findings integrate MEMO1 into an emerging network of molecules important for ameloblast development and provide a system to further interrogate the relationship of cytoskeletal and amelogenesis-related defects.

Published: July 2023

This study is the first to apply terror management theory to understanding smartphone addiction by examining the potential indirect effect of death anxiety on smartphone addiction via inclusion of smartphone in the self (i.e., self-expansion), affiliation motivation (the desire to connect with others) for emotional support, and smartphone use. The sample consisted of 1483 Chinese university students between the ages of 18 and 24 ( M = 19.14, SD = 1.03) who voluntarily completed an anonymous questionnaire survey. As hypothesized, death anxiety, inclusion of smartphone in the self, affiliation motivation, and smartphone use were directly, positively correlated with smartphone addiction. In addition, death anxiety exerted significant indirect effects via various pathways, including (i) affiliation motivation for emotional support and smartphone use and (ii) inclusion of smartphone in the self and smartphone use. Findings suggest that effective interventions for smartphone addiction should include targeting death anxiety, self-expansion, and affiliation need frustration.
Private Life Events as Antecedents for Public Employees’ Engagement and Burnout

Published: July 2023

While it is known that life events are predictive for psychological and physiological illnesses, empirical research on the relationship between private life events and their effect on work-related outcomes in a public sector context is scarce. Based on the extended job demands-resources model, this study argues that experiencing private life events may exercise spillover effects into the sphere of professional life affecting public employees’ work engagement and their risk of burnout. Longitudinal survey data from Switzerland reveals that negative private life events are associated with an increase in burnout but not necessarily lower levels of work engagement. Furthermore, experiencing transformational leadership exerts a mild stabilizing effect on work engagement in the face of private life events while public service motivation has no moderating effect. These findings have important implications for the practice and theory of public personnel management and leadership, employee performance, and well-being.
