Published: March 2023

This study was conducted at Arba Minch Zuria District of Gamo Zone, Southern Ethiopia to assess postharvest handling practices and marketing systems of honey. The district was selected purposively based on its beekeeping potential and stratified into three agro-ecological zones. Seven representative Kebeles from the District were selected proportional to their agro-ecological variations. A total of 156 beekeepers was selected using systematic random sampling technique. A cross-sectional study was conducted to generate data via an official survey. The data was analyzed using SPSS version 24 software. The result revealed that most (96.8%) of the beekeepers practiced traditional beekeeping system. Only 29.7% of the bee keepers strained their honey using sieve (68.4%), hand (21.1%) and a piece of cloth (10.5%). Plastic buckets (64.7%), tin and gallon (32.7%) and plastic sack (2.6%) were major honey handling materials. Most (90.4%) of the bee keeperssell honey to generate income and only 9.6% used honey for both sale and home consumption. Producers, consumers, retailers, tej houses and collectors were main actors involved in the honey value chain. Agro-ecology significantly influenced the market price of both crude and strained honey. The price of crude and strained honey in lowland location was significantly (P < 0.001) higher than highland and midland locations.
Classic Morita Therapy: Advancing Consciousness in Psychotherapy
Authors: LeVine Peg
Published: March 2023

This article chronicles “peripheral consciousness” and therapy developed by Japanese psychiatrist Shōma Morita, MD (1874-1938). As a contemporary of Freud, Morita challenged psychoanalysts who sanctioned an unconscious or unconsciousness (collective or otherwise) that resides inside the mind. From a human justice perspective, Morita’s formulation of consciousness releases clients from being solely responsible for their dysfunction. Morita was drawn to the earnest nature of analysts and how they strove to comprehend their patients’ anxieties and developmental histories. In fact, Morita developed his theories and methods with as much rigour as his Euro-American contemporaries, including Sigmund Freud, Wilfred Bion, Melanie Klein, Wilhelm Reich, Jean Charcot, Jacob Levy Moreno, Jacque Lacan, Carl Rogers, and Alfred Adler. In the early 1950s, especially, analyst Karen Horney progressed her grasp of Morita, Zen and psychotherapy while in Japan. Since cognitive science took hold in the 1970s, however, complex consciousness theories have lost footing in psychology and medical science. This article aims to reinstate “consciousness” as the dynamic core of Morita therapy. He advanced a phenomenal connexion between existentialism, Zen, Nature and the therapeutic role of serendipity; his views enhance Freud’s 1919 treatise on “The Uncanny”. The presence or absence of a theory of consciousness sways how, what, and where we practice and conduct research, as well as case formulation and health promotion. Morita is our forerunner of Ecopsychology and pioneer in consciousness studies. Pointedly, he equalised the strength between human-to-human attachment and human-to-Nature bonds by penetrating our anthropomorphic borders.
Meeting the Needs of a Culturally Diverse Nation: An Evaluation of a Behavioural Program Adapted to Treat Vietnamese Australians Experiencing Gambling Problems
Authors: Bertossa Sue , Phuong Sramek My , Fairweather Kate , Lawn Sharon
Published: March 2023

Equity is an important principle of health care in Australia, and redesigning health services to meet the needs of culturally marginalised groups has the potential to improve accessibility to psychotherapy. This paper describes the collaborative efforts of an ethno-specific service and a specialist treatment service to provide an evidence-informed intervention to treat Vietnamese Australian individuals experiencing gambling problems. Employing a clinical case audit tool and drawing on the evidence of 33 participants, the study identified which features of therapeutic practice had the most impact on retention and treatment completion. Moderate but influential adjustments to the delivery of a standard behavioural treatment program improved access, treatment adherence, and success for Vietnamese Australians experiencing gambling problems. These findings have significant implications for health care provision in a culturally diverse nation. Results highlight the importance of service adaptation to address under-utilisation and under-representation of psychotherapy services by culturally marginalised groups due to language and cultural barriers.
Interpersonal Rejection, Ostracism, and Mentalisation in Women’s Friendships: Clinical Implications for Rumination
Authors: Oehlman Forbes Deborah J.
Published: March 2023

Women’s friendships have long had cultural and psychological significance, particularly in the maintenance of positive social and emotional wellbeing. Inexplicable dissolution of these relationships correlates with a significant disruption of core human needs and mental health outcomes. Empirical research has found that ostracism, a variant of interpersonal rejection, is a distressing event since adult friendship attachment patterns are comparable to intimate partner relationships. In the field of mental health counselling and psychotherapy, theory can be an important precursor to intervention, but which theories and interventions may be suitable for post–friendship dissolution? Relational-cultural theory, a counselling and developmental framework, considers a broad range of psychological, social, healing connection, and relational experiences in the lives of women. Relational experiences starved of mutual empathic responses may evoke prolonged rumination in the friendship dissolution phase. In this regard, mentalisation-based treatment can help repair mental state affect such as prolonged rumination and restore emotion regulation. This is an unresearched topic that requires further investigation.
Tuning-in to Clients: The Use of Semiotics in Counselling
Authors: Edwards Thomas Mark
Published: March 2023

Semiotics is about signs, but more so about meaning-making. It therefore has immediate relevance to counselling. The current paper not only seeks to introduce semiotics to counsellors but also to offer skills and methods to enhance the ways in which practitioners see, hear, and understand their clients via the use of signs. In particular, five semiotic practices will be discussed: (1) the clinical relevance of categorising client signs; (2) the value of exploring the connotic meanings of client signs; (3) the effective use of a paradigmatic analysis to uncover hidden meanings; (4) the value of metaphor and irony to therapeutic conversations; and, (5) the necessity of understanding a client’s language code to avoid erroneous clinical judgements. Finally, in adopting the use of semiotics, practitioners are able to reconsider their practice by looking beyond client symptoms to engage meaningfully with entire sign systems, which confer additional and important clinical information.
Understanding the Cues and Strategies Counsellors Use to Develop Rapport With Clients Through Telephone Counselling
Authors: Phillip Karen , Beel Nathan , Machin Tanya
Published: March 2023

Rapport is a critical part of the counselling process, however most existing research has examined rapport in a face-to-face context. The aim of this study was to better understand the cues and strategies counsellors used to build rapport over the telephone. We interviewed nine counsellors with a range of qualifications and telephone counselling experiences. The data was analysed using thematic analysis. Three themes were identified: use of empathy, emphasis on paralanguage cues, and intentional harmonisation. The findings of this study contribute to the literature, counsellor training, and supervision by understanding the cues and strategies counsellors indicate they use to develop rapport with clients over the telephone.

Time Series Analysis for Digital Twins in Green Shipping
Authors: Avgeridis Lazaros , Lentzos Konstantinos , Skoutas Dimitrios , Emiris Ioannis Z.
Published: March 2023

A promising way for the waterborne industry towards decarbonization and emissions reduction is through digitalization and in particular via Digital Twins (DTs) technology. In this context, the DT provides insights for optimal decision-making, predicting potential future events, or even detecting irregularities in the behavior of the ship to reduce its carbon emissions and energy consumption. To achieve this, we propose an architecture for automated data capture, processing, and analysis. The analysis component of this infrastructure leverages machine learning (ML) algorithms for time series data, such as anomaly detection and forecasting. Importantly, to understand how these algorithms make a certain prediction we also provide a detailed look at current approaches used to interpret these models. Finally, we demonstrate a practical use case, where time series analysis can prove especially useful when applied to real-world vessel data.

Published: March 2023

Objectives: The use of e-cigarettes is on the rise in the United States (US). An understudied facet of e-cigarette use is the influence of social groups. The purpose of the present article is to examine the role of social groups in the use of e-cigarettes among Asian Americans.
Methods: We conducted 12 semi-structured interviews of Asian Americans who use e-cigarettes living in California. Interviews were transcribed and analyzed using thematic analysis. Results: Findings showed that e-cigarette use is normalized and encouraged among peer groups and
social gatherings, anecdotal success stories of their peers who were able to quit or reduce their use of combustible cigarettes using e-cigarettes were motivating, and vape shops provided a space for socialization and belonging. Conclusions: The findings illuminate that e-cigarette
use is a mediator in Asian American social groups as an activity for collectivity and connection. Public health researchers and practitioners can address nicotine use or addiction among Asian Americans through group or peer targeted prevention and intervention strategies.
What Can Help Students Cope with COVID-19? The Contribution of Psychological Capital, Selfcompassion, and Spirituality to Subjective Well-being
Authors: Hazan-Liran Batel , Walter Ofra
Published: March 2023

Objectives: In this research, we examined the academic and psychological coping of post-secondary students during the early stages of COVID-19. The main goal was to investigate correlations involving self- compassion, spirituality, psychological capital, and subjective well-being,
and evaluate the mediating role of self-compassion and spirituality in the relationship between psychological capital and subjective well-being.Methods: We had 257 participants (ages 19-59) complete 5 questionnaires: demographic and academic information, Psychological Capital Questionnaire,
Subjective Well-Being Index, Spiritual Intelligence Self- Assessment Inventory, and Self-Compassion Index. Results: We found a strong positive correlation between psychological capital, self-compassion, and subjective well-being. However, spirituality failed to show statistically significant
correlations with self-compassion and subjective well-being, with only weak correlations with psychological capital. Self-compassion positively mediated the relationship between psychological capital and subjective well-being, but not spirituality. Conclusion: These findings indicate
the role of positive psychological resources of post-secondary students in coping with a difficult situation like COVID-19.
Tejiendo alianzas en y desde la universidad. El caso de la Facultad de Educación Blanquerna (URL)

Published: March 2023

Universities have often been characterized by a sense of detaching from the real world, by a tendency towards hermetic compartments and by their rigidness. This paper presents the development policy of the relational dimension in higher education that has been led by a new managing position, the Networks and Partnerships Coordination Unit, responsible for the coordination of networks and partnerships. This policy contributes to a model that, beyond the isolated-subject curricula of university degrees, connects topics, disciplines, professionals and context needs through a policy that fosters and increases the social capital of the institution.

Through a diagnosis of internal and external connections, an action plan is designed. This is regulated by the principle of the universities’ social responsibility and establishes a short-, mid- and long-term action plan in relation to the internal and external dimension of our degree studies. This strategy is monitored through the Networks and Partnerships Unit. This Unit supervises, supports and centralizes different projects and actions, among which there are interdisciplinary inter-studies challenges, S-L within the territory and the develoment of a Magnet Project, among others. These are some of the examples that backbone this strategic line with the aim of transforming our higher education institution into a 360º-scope community educational Hub.

La institución universitaria se ha caracterizado habitualmente por un distanciamiento del mundo real, una tendencia a los compartimentos estancos y una considerable rigidez. El artículo presenta la política de desarrollo de la dimensión relacional de la Universidad a través de la figura de coordinación de redes y alianzas. Ésta, contribuye a un modelo que más allá de los planes de estudio de grado compuestos por asignaturas aisladas conecta materias, disciplinas, profesiones y necesidades del territorio a través de una política de cultivo e incremento del capital social de la institución.
A través de un diagnóstico de las conexiones internas y externas se diseña un plan de acción. Éste se rige por el principio de responsabilidad social de la Universidad y establece una estrategia a corto, medio y largo plazo en relación con la dimensión interna y externa de los estudios. Esta estrategia se monitoriza a través de la Unidad operativa de redes y alianzas que supervisa, apoya y centraliza la gestión de las distintas acciones entre las que hay retos interdisciplinarios intergrados, APS con el territorio o el desarrollo de un Proyecto Magnet. Son algunos de los ejemplos que vertebran esta línea estratégica que busca convertir la facultad en un Hub educativo comunitario de mirada 360º.
Materialidades del cuerpo online
Authors: Hernández Citlati
Published: March 2023

Los avances en las tecnologías de transmisión en directo de contenido multimedia y la creciente accesibilidad a los dispositivos móviles han creado un fuerte interés social por emitir actividades desde el espacio íntimo y cotidiano al espacio público digital. Este fenómeno se puede observar tanto en la aparición plataformas dedicadas específicamente a ello, por ejemplo, TikTok, Twitch, Periscope o Younow, como en la adaptación de otras que ya permitían compartir contenido multimedia de manera asincrónica. Ante este fenómeno, como diseñadora y artista multidisciplinar, me han ido acompañando distintos cuestionamientos en torno a la agencia de los cuerpos, de sus procesos identitarios en el contexto del livestream y de sus vínculos con todo aquello que opera en digital. Me pregunto por las prácticas y materialidades de los cuerpos cuando transitan entre lo público y lo privado, entre aquello en línea y lo fuera de línea. ¿Tan interesante es extender trozos de nuestra vida íntima y cotidiana en el espacio público digital?
Electromagnetic particle simulation of secondary electron multipactor characteristics in inner surface of 110 GHz microwave output window

The secondary electron multipactor on the inner surface of the output window is one of the main factors limiting the power capacity of high power microwave. Therefore, it is of great significance to carry out relevant research. In this work, the process of secondary electron multipactor and the resulting loss of power are numerically simulated by using the electromagnetic particle model with one-dimensional spatial distribution and three-dimensional velocity distribution at the microwave frequency of 110 GHz. The influences of microwave electric field at the surface and dielectric material type on the power loss are studied. The simulation results show that the electron number density is higher than the critical cut-off number density after the secondary electron multipactor has reached the steady state, but the microwave electric field does not show obvious change. This is because the electrons in a very high electrostatic field are mainly concentrated in the domain of several micrometers near the dielectric surface, which is far less than the corresponding skin depth. The electron number density in the multipactor steady state increases with the microwave electric field increasing, but the ratio of the power loss to the microwave power at the surface increases slowly. After the multipactor reaches the steady state, the number density of electrons near the sapphire surface is the highest, followed by the number density near the crystal quartz surface, and the number density near the fused quartz surface is the lowest, so the corresponding power loss decreases successively. In order to verify the accuracy of the model, the simulated value of the multipactor threshold is compared with the experimental data, and the difference between them is discussed.

Con los datos obtenidos se logró determinar para cada variedad, los requerimientos de frío y grados día en sus diferentes estados fenológicos, curvas de madurez de fruta y la calidad de esta al momento óptimo de cosecha para el año 2019.
Un nuevo paradigma arquitectónico : Campus Antumapu, Universidad de Chile.
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Ormazábal Cordero Rodrigo Andrés
Published: March 2023

Esta tesis trata sobre los origenes, influencias, presente y perspectivas de futuro del Campus Antumapu de la Universidad de Chile, el primer campus moderno silvoagropeacuario del país. En el año 1841, se inauguró la Quinta Normal de Agricultura, el primer lugar donde se enseñó agricultura en el país. Se ubicó en lo que entonces era un sector urbano periférico de Santiago. El objetivo era crear un campo experimental agrícola, didáctico y educacional, asociado con un parque público para la zona poniente de Santiago. Con el paso del tiempo, en este lugar se crearía la Facultad de Agronomía de la Universidad de Chile, que a raíz del crecimiento de la ciudad y la aparición de nuevas construcciones, fue necesario reubicarla, comenzando así la gestación del nuevo Campus. Para la decada de los 60’ existía una fuerte influencia del movimiento moderno, a esas alturas extendido por toda latinoamerica. Prueba de ello fue el surgimiento de diversos campus modernos en países como México, Venezuela y Cuba. En Chile este auge fue asociado con politicas públicas y diversas reformas educacionales que dieron pie a la realización de grandes obras. El Campus Antumapu, tiene la particularidad de ser el primer campus silvoagropecuario moderno en Chile. Es un caso interesante de estudiar por sus requerimientos, programas y propuesta arquitectónica-educativa. Los edificios fueron proyectados por el Grupo Taller de Arquitectura y Urbanismo, TAU. Emplazado en un inicio en la zona rural sur de Santiago, con el paso de los años su entorno se urbanizó y actualmente su borde se encuentra consolidado. Lo que en sus comienzos fue un Campus isla, hoy en día más bien da cuenta de un Campus aislado. Antumapu, es sinónimo de una política pública exitosa, y así lo demuestra su calidad de educación y valoración por su arquitectura después de 50 años. La investigación se divide en tres capítulos: el primero da cuenta de un primer paradigma, relacionado con la Escuela Práctica de Agricultura hasta la creación de la Facultad de Agronomía en la Quinta Normal (1842-1969) ; el segundo, indaga y analiza el desarrollo del Campus Antumapu, el nuevo paradigma arquitectónico; finalmente el tercer capítulo pone en valor el proceso evolutivo del campus hasta nuestros días, reflexionando sobre el presente y las perspectivas de futuro.

¿Cuál es la relación de la escuela pública con la ciudad neoliberal? En un momento en que la escuela pública disminuye su rol con respecto a la visión contemporánea de ciudad, Se propone una revisión tanto teórica como práctica del periodo de gobierno de Eduardo Frei Montalva y la llamada “Revolución en Libertad”, momento en que el Estado cumplía un rol regulador a través de empresas públicas como la Sociedad Constructora de Establecimientos Educacionales (SCEE) en escuelas (educación) y la Corporación de Mejoramiento Urbano (CORMU) en vivienda. Estas organizaciones plantearon un modelo de ciudad con conceptos tanto ideológicos como arquitectónicos similares; pensado desde lo colectivo y lo común; y materializado técnicamente a través de métodos de estandarización y masificación. Sin embargo, los grandes cambios políticos que acontecieron en Chile desde 1973 modificaron drásticamente la dirección de estas instituciones hasta su posterior cierre. En la actualidad, ambos proyectos permanecen como vestigios en la ciudad de un futuro inconcluso con la capacidad de ser revisitado y relacionado. Se propone una la relación entre vivienda y educación entendidas como un proyecto que puede repercutir en las lógicas de la ciudad (proyecto-ciudad) comprendiendo una visión pasada de mayor carácter social como una herramienta de resistencia a los esfuerzos contemporáneos mayormente dirigidos al crecimiento económico.¿Cuál es la relación de la escuela pública con la ciudad neoliberal?

De cicatriz a costura urbano-ecológica: Américo Vespucio como proyecto detonante para el sistema de infraestructura verde de Santiago
Authors:   ,   Pontificia Universidad Católica de Chile, González Verdugo Camila Ignacia
Published: March 2023

Santiago está ubicado en el valle central de Chile, ésta zona, tiene un importante valor ecológico para el planeta debido a su alto nivel de especies nativas y endémicas. Sin embargo, el crecimiento constante de la ciudad que avanza hacia zonas cordilleranas, valles aledaños y zonas rurales pone en riesgo la biodiversidad de la región. Este crecimiento urbano genera fragmentación de áreas verdes y naturales poniendo en riesgo la conservación ecológica del lugar. La investigación plantea la necesidad de establecer un sistema de infraestructuras verdes, que aseguren la conservación ecológica de la región y contribuya a una adecuada relación entre los habitantes de la ciudad de Santiago y el entorno natural. Para esto, se observa en la circunvalación Américo Vespucio la oportunidad de ser el proyecto detonante que el sistema necesita, consolidándose como una infraestructura de movilidad metropolitana que aporte a la conexión ecológica y hacer de faja de transición entre lo que ocurre en las zonas periurbanas, donde la ruralidad y la urbanización dispersa genera mayor biodiversidad y la ciudad consolidada, donde los parques urbanos juegan un rol clave. Se plantea entonces un cambio de estándar de la actual autopista mediante un proyecto urbano que genere ciudad en sus bordes, vinculada a los elementos naturales y verdes que la circunvalación atraviesa con la finalidad de acercar la naturaleza a la ciudad y transformarse en una costura urbana. Al hablar de un sistema de infraestructuras verdes para Santiago se hace imposible pensar una escala menor a la regional, sin embargo, se escogió un área representativa en la zona norte de la ciudad para desarrollar el proyecto, que es replicable a toda la circunvalación. En esta área se detallan las distintas partes del sistema, que abarcan desde la escala regional con propuestas como la consolidación del Cinturón Verde-Productivo, un parque de borde, que marca un cambio en la morfología de la ciudad, y cuñas verdes que introducen biodiversidad a la urbe. La escala de intervención considera un cambio definitivo en el estándar de las autopistas urbanas donde se les exige un mínimo ecológico y el desarrollo de áreas verdes que conectan los hitos naturales para llegar finalmente a una escala barrial con la propuesta de una macro-manzana como célula urbana que terminan de consolidar el sistema.
Avenida Destino : bulevar como herramienta de regeneración urbana en Portales Poniente
Authors:   ,   Pontificia Universidad Católica de Chile, Prieto Silva Camila
Published: March 2023

Considerando sus dimensiones y proximidad con el Parque Quinta Normal, ¿por qué la Avenida Portales Poniente se encuentra en tal degradación y no se constituye como un atractivo urbano? Dentro de la ciudad, la Quinta se caracteriza como un área en la cual se disponen diferentes piezas con condiciones e identidades propias. Aun cuando existe una coexistencia física, se reconocen distintas sinergias que han sido desgastadas o desaparecido a través del tiempo. Tras las divisiones prediales de la Quinta Normal de Agricultura, el polígono se atomizó en una serie de administraciones menores, cada cual, con su propio sistema de acceso, cierre y ejecución. Estas operaciones condujeron a que el tramo entre Matucana y General Velásquez pasara de tener una condición histórica como eje central dentro de un sistema a actuar como una frontera de separación entre las unidades respectivas. Mediante una discusión sobre el prototipo Avenida-Destino, un estudio histórico, levantamiento y análisis, se propone un proyecto de arquitectura que impulse la reconfiguración de Portales Poniente. El modelo de Bulevar, el cual integra la noción de avenida y parque, se manifiesta como una herramienta de regeneración urbana que permita establecer un nuevo sistema de intensidad urbana - cuyo núcleo incluye el diseño de programa, flujos y actividades - que permita conectar y activar las relaciones entre los distintos enclaves fraccionados

Published: March 2023

There are many traditional rice varieties being cultivated in various parts of Kerala. While cultivating them, farmers follow traditional practices using special type of implements and tools. But now the area has drastically declined and they are confined to certain pockets and mostly taken up by older farmers. Wayanad and Malappuram districts of Kerala were purposively selected for the study. Sixty farmers from Wayanad district and thirty farmers from Malappuram district were randomly selected. Marketing behaviour of farmers has a great role in the sustainable development and promotion of traditional rice varieties. The study revealed that marketing behaviour of majority of the farmers could not be rated as high. Marketing behaviour of farmers was significantly influenced by age, education, gender, occupation and experience. Higher level of education had a significant role in the development of marketing behaviour among farmers. Shortage of skilled labour, lack of irrigation facilities and lack of transportation facilities were the main constraints faced by the traditional rice farmers.

Authors: Rakibuzzaman Md. , Rahman M. M. , Hossain M. S. , Hossain Md. Emam
Published: March 2023

A study was conducted in organic and intensive tomato growing areas located in Manikganj and Narsingdi districts of Dhaka division. A total of 30 organic tomato growers were selected from 5 randomly selected villages of Manikganj and Narsingdi. Data were collected from September 2020 to September 2021. Most frequently used insect pest management strategies by the organic farmers under the study areas were; T0=Untreated control (Used resistant varieties only), T1=Pheromone trap (Plastic pot), T2=Sticky trap+ Neem leaf powder @ 1kg/10L of water at 7 days interval, T3=Bait trap+ Neem leaf powder @ 1kg/10L of water at 7 days interval, T4=Light trap+ Mahogany seed powder @ 20gm/L of water at 7 days interval and T5= Pheromone trap + Trichogramma evanescens (100 points ha-1 at 500 wasps per point). For the untreated control of tomato fruit borer, T1=Pheromone trap (Plastic pot) was the most frequently used (52.67%) in the study area whereas T5= Pheromone trap + Trichogramma evanescens (16.67%) was used by the least number of organic farmers besides untreated control T0 (8.67%). The highest benefit cost ratio was 1.51 recorded from the treatment T5= Pheromone trap + Trichogramma evanescens, lowest benefit cost ratio was 1.30 recorded for tomato production from the untreated control treatment T0. Due to reduced operating costs, the benefit-cost ratio for producing organic tomato was comparable to and close to that of growing high yielding tomato using inorganic methods. The difference between the BCR of organic tomato production procedures and inorganic tomato production practices was eventually eliminated by high market price and rising demand of organic produces.

Objective

To compute penetrance and recurrence risk using a genome‐wide PRS (including and excluding the APOE region) in families with Alzheimer's disease.

Methods

Genotypes from the National Institute on Aging Late‐Onset Alzheimer's Disease Family‐Based Study and a study of familial Alzheimer's disease in Caribbean Hispanics were used to compute PRS with and without variants in the 2 MB region flanking APOE. PRS was calculated in using clumping/thresholding and Bayesian methods and was assessed for association with Alzheimer's disease and age at onset. Penetrance and recurrence risk for carriers in highest and lowest PRS quintiles were compared separately within APOE‐ε4 carriers and non‐carriers.

Results

PRS excluding the APOE region was strongly associated with clinical and neuropathological diagnosis of AD. PRS association with AD was similar in participants who did not carry an APOE‐ε4 allele (OR = 1.74 [1.53–1.91]) compared with APOE‐ε4 carriers (1.53 [1.4–1.68]). Compared to the lowest quintile, the highest PRS quintile had a 10% higher penetrance at age 70 (p = 0.0006) and a 20% higher penetrance at age 80 (p < 10e‐05). Stratifying by APOE‐ε4 allele, PRS in the highest quintile was significantly more penetrant than the lowest quintile, both, within APOE‐ε4 carriers (14.5% higher at age 80, p = 0.002) and non‐carriers (26% higher at 80, p < 10e‐05). Recurrence risk for siblings conferred by a co‐sibling in the highest PRS quintile increased from 4% between the ages of 65–74 years to 39% at age 85 and older.

Interpretation

PRS can be used to estimate penetrance and recurrence risk in familial Alzheimer's disease among carriers and non‐carries of APOE‐ε4.

Due to limited information, identifying suitable cannabidiol (CBD) dominant industrial hemp (Cannabis sativa L.) cultivars and optimal planting date are critical for hemp commercialization for CBD production in Florida. Two field trials were conducted with seven cultivars planted on three different dates from late April to late June. The cultivars were received from two different suppliers (Kentucky and Colorado) representing their adaptation. Plant growth parameters such as plant height and green canopy cover were recorded at 2−3 weeks intervals during crop growth. Temporal CBD and Δ‐9‐tetrahydrocannabinol (THC) concentrations in developing flowers were analyzed weekly beginning two weeks after flowering until maturity. The final floral biomass yield was measured at harvest. CBD and THC concentration curve over crop growing season varied among the tested cultivars. High positive correlations between CBD and THC concentrations (R2 = 0.88−0.98) were observed in all cultivars. This resulted in similar CBD/THC ratios across all planting conditions. Earlier planting resulted in higher CBD, THC, and floral biomass yield in a few cultivars, with no significant effect in most cultivars. Cultivars adapted in Kentucky performed better compared to Colorado in floral biomass and CBD yield. However, THC concentrations in the cultivars adapted in Kentucky mostly exceeded the acceptable legal threshold (0.3% THC) at harvest. Results indicate cultivar performance was affected more by genetics compared to planting date. Screening more cultivars adapted to regions of similar latitudes and environmental conditions is necessary to identify suitable hemp cultivars for Florida or similar climatic conditions.

Herein, we design and synthesize a series of oligomers [Ir(ppy)2(dabpy)‐ODPA]n (D1‐n) by copolymerization of [Ir(ppy)2(dabpy)][PF6] (D2) with 4,4′‐Oxydiphthalic anhydride (ODPA), to resolve the problem of simultaneous improvement of stability and activity of classical iridium complex for photocatalytic water‐splitting. Fourier‐transform infrared spectroscopy, X‐ray photoelectron spectroscopy, solid‐state nuclear magnetic resonance, and gel permeation chromatography results indicate that the degree of polymerization (n) of D1‐n could be tuned by the synthesis method. The best photocatalytic performance is reached by D1‐n with n at of 2 and/or 3 (D1‐2/3), which exhibits a photocatalytic lifetime up to 676 h and a photocatalytic hydrogen evolution of 162055.1 μmol·g‐1. Compared with classical iridium complex D2, the photocatalytic lifetime of D1‐2/3 is about 38 times longer and the photocatalytic activity is 1.3 times higher. Further increase of n leads to a decrease in both photocatalytic lifetime and activity. According to the spectroscopic characterizations, photoelectrochemical experiments, and density functional theory calculation, the significantly enhanced photocatalytic performance of D1‐2/3 originates from the oligomeric structure. The oligomer chain of D1‐2/3 with suitable length acts as a large steric hindrance to reduce the undesired photoinduced decomposition and prolong its lifetime. The possible coupling of adjacent Ir complexes in D1‐2/3 lowers the energy gap and increases the utilization of visible light, which overcomes the adverse effect of large steric hindrance and finally improve the activity. This work first provides a simple strategy for constructing oligomeric Ir photosensitizers to simultaneously achieve long lifetime and high activity, it will lay the foundation for the design of highly efficient photosensitizers in the future.

Published: March 2023

In recent years, circularly polarized luminescence (CPL) has witnessed a renaissance, due to the increased popularity of CPL as a spectroscopic technique and greater accessibility to instrumentation. New efficient CPL emitters have been designed and many applications, ranging from electronic devices to microscopy have been proposed. Most examples of CPL are within the visible range, while few cases of near infrared (NIR) CPL active complexes are available. NIR‐CPL compounds may have applications in the telecommunication industry, electronic devices and bioassays. In the following, we shall give an overview of the recent developments allowing for the measurements of NIR‐CPL, and describe the chiroptical properties of metal complexes which achieve this feat.

Organic solar cells (OSCs) have advanced rapidly due to the development of new photovoltaic materials. However, the long‐term stability of OSCs still poses a severe challenge for their commercial deployment. To address this issue, a dimer acceptor (dT9TBO) with flexible linker is developed for incorporation into small‐molecule acceptors to form molecular alloy with enhanced intermolecular packing and suppressed molecular diffusion to stabilize active layer morphology. Consequently, the PM6 : Y6 : dT9TBO‐based device displays an improved power conversion efficiency (PCE) of 18.41 % with excellent thermal stability and negligible decay after being aged at 65 °C for 1800 h. Moreover, the PM6 : Y6 : dT9TBO‐based flexible OSC also exhibits excellent mechanical durability, maintaining 95 % of its initial PCE after being bended repetitively for 1500 cycles. This work provides a simple and effective way to fine‐tune the molecular packing with stabilized morphology to overcome the trade‐off between OSC efficiency and stability.

Four copper (II) complexes bearing tris‐(2‐pyridyl)‐pyrazolyl borate (Tppy) ligand with corresponding chloride (Cu‐1), aqua (Cu‐2), azide (Cu‐3), and thiocyanide (Cu‐4) substitutions were synthesized and characterized by spectroscopic and analytical methods. Spectroscopic and molecular docking studies were employed to investigate the interactions of these complexes with calf thymus (CT) DNA and bovine serum albumin (BSA). The results inferred intercalation binding mode of the complexes with DNA. All the complexes exhibited good binding with BSA as well. In addition, the binding efficacy of the Cu (II) complexes with SARS‐Cov‐2 was tested in silico. Further, in vitro anticancer activity of the complexes was investigated against the HeLa‐cervical, HepG2‐liver and A549‐lung cancer, and one normal (L929‐fibroblast) cell line. IC50 values unveiled that the complexes were more active than cisplatin against all three cancer cells. It was understood that complex Cu‐3 containing azide substitution displayed the highest activity on the HeLa cell line (IC50 = 6.3 μM). More importantly, TppyCu (II) complexes were not active against the normal cell line. Lastly, the acridine orange/ethidium bromide (AO/EB) and 4′,6‐diamidino‐2‐phenylindole staining assays indicated that Cu‐3 induced cell death in HeLa cells at the late apoptotic stage. This complex also efficiently generated ROS in HeLa cells promoting apoptosis as understood from the DCFH‐DA assay.
