Authors: Dwyer Bridget , Flathers Matthew , Burns James , Mikkelson Jane , Perlmutter Elana , Chen Kelly , Ram Nanik , Torous John
Published: May 2024

BACKGROUND

Low engagement with mental health apps continues to limit their impact. New approaches to help match patients to the right app may increase engagement by ensuring the app they are using is best suited to their mental health needs.

OBJECTIVE

This study aims to pilot how digital phenotyping, using data from smartphone sensors to infer symptom, behavioral, and functional outcomes, could be used to match people to mental health apps and potentially increase engagement

METHODS

After 1 week of collecting digital phenotyping data with the mindLAMP app (Beth Israel Deaconess Medical Center), participants were randomly assigned to the digital phenotyping arm, receiving feedback and recommendations based on those data to select 1 of 4 predetermined mental health apps (related to mood, anxiety, sleep, and fitness), or the control arm, selecting the same apps but without any feedback or recommendations. All participants used their selected app for 4 weeks with numerous metrics of engagement recorded, including objective screentime measures, self-reported engagement measures, and Digital Working Alliance Inventory scores.

RESULTS

A total of 82 participants enrolled in the study; 17 (21%) dropped out of the digital phenotyping arm and 18 (22%) dropped out from the control arm. Across both groups, few participants chose or were recommended the insomnia or fitness app. The majority (39/47, 83%) used a depression or anxiety app. Engagement as measured by objective screen time and Digital Working Alliance Inventory scores were higher in the digital phenotyping arm. There was no correlation between self-reported and objective metrics of app use. Qualitative results highlighted the importance of habit formation in sustained app use.

CONCLUSIONS

The results suggest that digital phenotyping app recommendation is feasible and may increase engagement. This approach is generalizable to other apps beyond the 4 apps selected for use in this pilot, and practical for real-world use given that the study was conducted without any compensation or external incentives that may have biased results. Advances in digital phenotyping will likely make this method of app recommendation more personalized and thus of even greater interest.
The Middle-Class Muslims’ Responses Toward the Salafi Da’wah: A Study on Hijrah celebrities
Authors: Setiana Dewi Oki , Khoirul Fata Ahmad , Fauzi Mahfudh
Published: May 2024

This study unravels how Indonesian celebrities who submitted to Salafi Islam (popularly called hijra celebrities) responded to some notable Salafi teachings. Like in many Muslim countries, such as Türkiye, Pakistan, and Egypt, Salafism is increasingly attracting followers from the middle class who then express their Salafism in public visibility, or called “active piety”. The data for this article was collected through in-depth interviews with Salafi preachers (dais) and celebrities who actively participated in the Islamic meetings held or taught by these preachers. This study uses a cultural studies approach, in which Hall's theory of encoding-decoding is used to analyse the active role of hijrah celebrities in receiving messages conveyed by Salafi preachers. This study reveals that the Salafi preachers used the educational approach in their propagation (da’wah) through religious education forums using clear guideline books. Meanwhile, the celebrities’ responses toward this Salafi propagation varied, i.e., dominant hegemony, negotiation, and opposition, with negotiation being the most frequent. In general, the celebrities accepted the Islamic teachings from their Salafi teachers, except for several issues that they considered less relevant to their lives. This study also found the fact that the hijrah celebrities, as recipients of information, did not passively receive information, but they classified, selected, and utilised the information received from the Salafi preachers and adapted it to their needs.
The Empire Writes Back: Deconstructive Paradigms in Jack Maggs
Authors: Wan Shengjia
Published: May 2024

In his ‘neo-Victorian novel’ Jack Maggs, Peter Carey seeks to retell Charles Dickens’s classic Great Expectations from the postcolonial perspective. Jack Maggs, a stand-in for Dickens’s Magwitch, is shaped into the protagonist in Carey’s work, which telegraphs the author’s close attention to marginalized groups in British society. By endowing the silent ‘other’ with the opportunity to speak, Carey attempts to deconstruct the hegemony of the Anglo-centric narrative and reshape the unique cultural identity of Australians, which simultaneously embodies the self-reflexivity of his literary practice.

Published: May 2024

La memoria material se expresa en la vivienda como una secuencia entre arquitectura y sociedad, donde el espacio se sustenta en símbolos. El objetivo de este artículo es recuperar la relación que existe entre el orden de los edificios y los materiales que los mantienen en la memoria oral de sus habitantes. La metodología se basa en el análisis de materialidad de un barrio histórico, las microhistorias registradas in situ y la verificación en el archivo fotográfico. Los hallazgos expresan la construcción amalgamada de la vivienda con las ideologías sociales, a partir de los eventos que se fijaron en la memoria colectiva de los habitantes. Además de despejar la noción del patrimonio institucionalizado, que se enfoca en catálogos y listas de edificios por sus valores canónicos, la memoria material de la vivienda pone el acento en los valores sociales heredados que se plasman en lo ordinario de la vida doméstica.

Authors: Margos Nikolaos Panagiotis , Papasteriadis Evaggelos
Published: May 2024

Introduction Implantable permanent pacemaker function is supported by
their energy sources by a mean period of 8,8 to 12,4 years. We
previously published this case of a patient with a normally functioning
VVI pacemaker, 31 years after implantation. Methods and Results In this
report, we state that the device is still functioning normally 40 years
after implantation. The most recent device interrogation revealed pacing
threshold of 0.9 V/0.5 ms. Holter monitoring for 24 hours recorded a
total of 98.707 beats with 97,78% paced beats, without any indication
of pacemaker malfunction and with stable heart rate at 70-71 bpm.
Conclusion Most patients with implantable devices have the appropriate
follow-up and settings of low energy consumption. Manufacturing
companies are mainly considered responsible for achieving prolonged
device longevity, focusing on the goal of high energy capacity of future
devices.
Effectiveness of South Africa’s network of protected areas: Unassessed vascular plants predicted to be threatened using deep neural networks are all located in protected areas
Authors: Kandolo B. Samuel , Yessoufou Kowiyou , Kganyago Mahlatse
Published: May 2024

Globally, biodiversity is at risk of extinction, and megadiverse
countries become key targets for conservation. South Africa, the only
country hosting three biodiversity hotspots, harbours tremendous
diversity of at-risk species deserving to be protected. However, the
lengthy risk assessment process and the lack of required data to
complete assessments is a serious limitation to conservation since
several species may slide into extinction while awaiting risk
assessment. Here, we employed deep neural network model integrating
species climatic and geographic features to predict the conservation
status of 116 unassessed plant species. Our analysis involved in total
1072 plant species and 112 066 occurrence points. The best-performing
model exhibits high accuracy, reaching up to 83.6% at the binary
classification and 56.8% at the detailed classification. Our
best-performing model predicts that 32% and 8% of Data Deficient and
Not-Evaluated species are likely threatened, respectively, amounting to
a proportion of 24.1% of unassessed species facing a risk of
extinction. Interestingly, all unassessed species predicted to be
threatened are in protected areas, revealing the effectiveness of the
South Africa’s network of protected areas in conservation, although
these likely threatened species are more abundant outside protected
areas. Considering the limitation in assessing only species with
available data, there remains a possibility of a higher proportion of
unassessed species being imperiled.

Boreal Forest Fire Causes Daytime Surface Warming During Summer to Exceed Surface Cooling During Winter in North America
Authors: Helbig Manuel , Daw Lilly , Iwata Hiroki , Rudaitis Lukas , Ueyama Masahito , Živković Tatjana
Published: May 2024

Boreal wildfires impact surface climates with consequences for plant
physiology, permafrost thaw, and carbon fluxes. Post-fire temperatures
vary over decades due to successional changes in vegetation structure
and composition. Yet, the underlying biophysical drivers remain
uncertain. Here, we quantify surface climate changes following fire
disturbances in the North American boreal forest and identify its
dominant biophysical drivers. To do so, we analyse multi-year
land-atmosphere energy exchange and satellite observations from across
Canada and Alaska. We find post-fire daytime land surface temperatures
to be substantially warmer for about five decades while winter
temperatures are slightly cooler. Post-fire decadal changes are
characterised by a decrease in leaf area index during the first decade,
a sharp increase in snow cover period surface albedo, and a decrease in
the efficiency of heat transfer for about 2-3 decades. Evaporative
fraction increases in the first three decades before returning to lower
values again. We find that warming is mainly explained by a decrease in
the efficiency of heat transfer while cooling is additionally explained
by increasing surface albedo. We estimate that current daytime surface
temperatures of the boreal biome of Canada are 0.18 °C warmer in the
summer and 0.04 °C cooler during the winter due to fire. For a scenario
with a strong increase in burned area, we estimate doubled warming from
fire until 2050. Our study highlights the potential for accelerated
surface warming in the boreal biome with increasing wildfire activity
and disentangles the biophysical drivers of fire-related surface climate
impacts.
Numerical Simulation of Flow Resistance due to the Limnoperna fortunei Attachment
Authors: Hou Qingqing , Sun Chengfan , Xu Yuncheng , Xu Mengzhen
Published: May 2024

High-density attachment of Limnoperna fortunei (LF) would lead to the
increase of flow resistance, which has posed big challenges to the
normal operation of water conveyance projects. It is very necessary to
quantify the flow resistance caused by the attachment of LF. In this
study, a 3D geometric model of LF was generated based on real images.
Attachment models of LF were generated with different densities and
mussel size distributions, whose geometric characteristics were
evaluated by some fundamental physical quantities, including attachment
thickness, bed coverage, surface vertical roughness, and roughness
concentration. Furtherly, a 3D numerical model with specific boundary
conditions was established in OpenFOAM to simulate the flow over the LF
attachment. Body-fitted mesh was generated using snappyHexMesh based on
the LF attachment model. The results show that in high-density
scenarios, a big wake zone formed inside LF attachment by the combined
effects of each individual LF. Turbulence kinetic energy distribution
indicated that LF attachment would cause viscous dissipation thus
leading to more energy loss. The flow structure inside LF attachment was
controlled by the size and spacing between each individual LF. Manning’s
n values were calculated based on the CFD results at different
densities. The results show that the flow resistance of LF attachment
also followed the classic flow regimes, where in the skimming flow
regime, the mussel size distribution played a non-negligible role.
Higher flow speed resulted in larger flow resistance, and n could
increase more than 90% compared to the scenario without LF attachment.

Different students have different preferences for learning methods. Some of the students might prefer visual or audio reading or kinesthetic learning. It is believed that the student’s preferences of learning methods might help the students understand more about the subject and hence contribute to their academic performance. Therefore, this study investigates whether the students’ preferences for learning methods are influenced by the courses they registered for and the gender, and age of the students. A sample of 341 students from different backgrounds was selected in this study comprised of students from the Faculty of Business and Management, Faculty of Accountancy, Faculty of Graphic Design, and Faculty of Nursing in Universiti Teknologi MARA (UiTM) Puncak Alam. The findings show that course and gender play an important role in student’s preferences for learning methods while age is not the significant variable. There is a very high positive correlation between courses and preferences of learning methods, while age and gender have a high positive correlation toward preferences of learning methods. This study might help educators in tailoring their lectures to the students’ preferences of learning methods, thus contributing to the academic performance of the students.

Published: May 2024

The burgeoning manufacturing sector has been the primary driver of Malaysia's substantial and notable economic expansion. Notwithstanding these, the Malaysian manufacturing sector remains afflicted by concerning safety concerns. To enhance the situation, the Malaysian government has proposed the use of self-regulatory safety management systems (SMS). However, there are doubts about the employees' preparedness to adopt this measure. Implementing SMS has numerous complexities. Despite progress made in the SMS technique, failures continue to be prevalent. There is a lack of literature regarding the perspectives of the manufacturing industry regarding their concerns regarding the implementation of SMS. This study aimed to ascertain the presence of safety practices derived from SMS elements and identify the characteristics associated with the successful application of SMS. The anticipation is that the outcomes of this study will contribute to the successful implementation of SMS. The findings of this research will be of significant importance to the stakeholders and policymakers.

Are Bovine Calves Ideal Bio-Indicators for Endemic Fluorosis?
Authors: SL* Choubisa
Published: May 2024

Fluoride occurs naturally in water, rocks, and soils or from modern industrial processes, such as such as coal burning power generation stations, and manufacture of steel iron, aluminium, zinc, phosphorus, chemical fertilizers, bricks, glass, plastics, cement, hydrofluoric acid, etc. Long-term regular exposure to fluoride through fluoride-contaminated drinking water and airborne fluoride can cause serious and disabling health effects in both humans and animals. However, in mammalian species, the skeleton in particular is relatively more sensitive or susceptible; growth on the bones and fusion of the joints cause lameness and lack of mobility at an early age. Teeth can become severely worn and damaged, often losing their enamel. Fluorosis has been well studied at different fluoride concentrations in drinking waters in different species of domestic animals, such as cattle (Bos Taurus), water buffalo (Bubals bubalis), sheep (Ovis Aries), goat (Capra hircus), camel (Camelus dromedaries), horse (Equus caballus), donkey (E. asinus), etc. Recent studies indicate that among these animals, bovines (cattle and buffalo) are found to be relatively less tolerant to fluoride toxicity and suffer from more severe fluorosis than other animal species. Their calves are also found to be relatively more sensitive to fluoride toxicity than immature animals or juveniles of other species. Cattle and buffalo calves were found to suffer from dental fluorosis even at fluoride concentrations less than 1.5 ppm in drinking water and a relatively high prevalence of 58.42% and 62.82%, respectively was observed. Therefore, bovine calves can be considered an ideal bio-indicator for endemic fluorosis as they show the earliest pathognomonic sign of chronic fluoride intoxication in the form of dental fluorosis compared to other animal species. Whether fluorosis is endemic in any geographical province or region can be interpreted from the evidence of dental fluorosis in bovine calves, which is highlighted and focused in the present editorial.

Accelerating the Height Increase of Mersawa (Anisoptera marginata) Seedlings through Inundation Height with and without Water Treatments
Authors: Achmad Basir , Faisal  , Suhartati
Published: May 2024

Deforestation on peatlands in Indonesia has become an important issue. To restore the peatland condition, planting native tree species such as mersawa (Anisoptera marginata) is required. One of the problems with planting is the frequent occurrence of inundation at planting sites. The study aimed to analyze the inundation height, which accelerated the height increase of mersawa seedlings in acid or neutral water conditions. The method used was experimental research with a factorial completely randomized design. Factors studied were inundation height, consisting of without inundation, inundation at polybag height, inundation between the tips of the polybags and the apices of the plants, and inundation reaching the apices of the plants. The water composition consisted of peat swamp water, peat swamp water mixed with boiler ash from palm oil mill, and peat swamp water mixed with dolomite lime. The treatment of inundation between the tips of the polybags and the apices of the plants led to the highest height growth, while the lowest were the seedlings without inundation. The interaction between the inundation height and the water composition had a survival percentage of 100%, while the seedlings inundated up to the seedling apices with water treatments had a survival rate of 16%.
Keywords: Anisoptera marginata, inundation, peat swamp water, seedling growth

Las babosas son plagas importantes de cultivos en muchos ecosistemas a nivel mundial y también en Colombia. Esta investigación tuvo como objetivo evaluar la actividad molusquicida de tres extractos de Agavaceae; Agave americana, Furcraea bedinghausii y F. andina, como alternativas para el control de babosas en papa criolla, obtenidas por dos métodos de extracción, jugo y fracción. Se realizó una investigación experimental en un ensayo de campo en un cultivo de papa. Tres tratamientos consistieron en jugos de las tres plantas mencionadas al 20% y otros tres con extractos acuosos de las hojas picadas de las plantas a 4kg/10L de agua, un tratamiento con Tierra de Diatomeas como estándar de producción y un testigo sin tratamiento. Los extractos vegetales de Furcraea andina, tanto en jugo como en trozos, obtuvieron más del 60% de eficacia técnica en papa criolla con diferencia estadística con el control y resultados similares al testigo de producción estándar, Tierra de Diatomeas. Los tratamientos que lograron mayor estabilidad para reducir el daño por babosas en papa fueron los extractos vegetales de Furcraea andina, tanto en forma de jugo como en fracciones.

El desarrollo de la humanidad, entre revoluciones industriales y tecnológicas, ha causado daños a la ecología del planeta. Tal situación ha permitido la emergencia del concepto de desarrollo sostenible, como un proceso social conformado por valores, modelajes, aprendizajes sociales, comportamientos humanos, culturales y ambientales. El objetivo fue describir la noción del desarrollo sostenible implicado en el contexto universitario desde las prácticas andragógicas en la Universidad Nacional Experimental Simón Rodríguez. La investigación adoptó el paradigma interpretativo naturalista y el método etnográfico, donde se aplicó la observación participante, diario de campo y la entrevista en profundidad a cinco docentes de la institución. La información obtenida fue procesada con base a categorización, saturación, triangulación y teorización. Las conclusiones señalan que la universidad reconoce en sus prácticas andragógicas los elementos importantes del desarrollo regional y local, para la búsqueda del desarrollo humano y sostenible, por medio de procesos continuos para la formación de competencias.

El desarrollo industrial en palma ha conducido a una mayor generación de residuos, por lo que esto se ha convertido en una problemática ambiental y económica. Por tal motivo, se implementó el método adecuado para la obtención del biocarbón a partir del raquis de palma aceitera. De esta manera, se realizó una investigación descriptiva, no experimental, en tres muestras de raquis homogeneizado de 500 gramos cada una, donde se les determinó: contenido de humedad del raquis, contenido de aceite del raquis, y rendimiento del biocarbón en base a materia seca. Se obtuvo una humedad promedio de 2,58 %, un contenido de aceite de 16,13 % y rendimientos en el biocarbón entre 76,96 y 79,24 %. Así, se evidencia que el método de obtención del biocarbón a partir del raquis de palma es satisfactorio, debido a los altos rendimientos alcanzados; generando mejor disposición de residuos al ofertar el biocarbón como fertilizante.

La autenticación por medio de la biometría facial se ha vuelto fundamental para verificar la identidad de las personas en transacciones en línea, ya que mecanismos clásicos como la autenticación por nombre de usuario y contraseña han demostrado ser poco fiables, ya que los usuarios suelen escoger contraseñas que son fáciles de recordar. Sin embargo, el avance en la fabricación de modelos con materiales como el látex, el aumento en la calidad de las impresiones y la mejora en las resoluciones de las pantallas han exigido que los sistemas de detección de fraude se adapten rápidamente a las nuevas condiciones. El presente trabajo muestra una propuesta para abordar el problema de la detección de ataques de presentación por medio de la extracción del flujo óptico y los puntos de referencia facial y su análisis por medio de una red siamese. Para evaluar el modelo propuesto, se utilizaron tres data sets: Rose-youtu, Replay-attack y Replay-mobile, y las métricas HTER y EER.

The background of the phenomenon of the characteristics of toxic pastors is the rise of pastors (servants of God) who abuse their priesthood to manipulate the congregation; even in more extreme cases, they dare to sexually abuse their own congregation. Even though they are people who are equipped with good knowledge and a spiritual life, Therefore, this study aims to describe and find out what the impact of the attitude of toxic pastors is and how efforts should be made so that pastors can control their own spiritual and physical lives. So, in this case, the researcher uses the literature study method, which shows that toxic pastors have a detrimental impact on the church and congregation. To overcome this, they must be ready to give up their lusts, maintain priestly holiness, and always have vigilance of faith. Keywords: God's Servant, Lust, Congregation, Role of God's Servant, Toxic
