Mobile Phone Apps for Intimate Partner and Sexual Violence Prevention and Response: Systematic Search on App Stores
Authors: Draughon Moret Jessica , Todd Angela , Rose Lauren , Pollitt Erin , Anderson Jocelyn
Published: February 2022

Background

Since the 2008 advent of the smartphone, more than 180 billion copies of apps have been downloaded from Apple App Store, with more than 2.6 million apps available for Android and 2.2 million apps available for iOS. Many violence prevention and response apps have been developed as part of this app proliferation.

Objective

This study aims to evaluate the prevalence and quality of freely available mobile phone apps targeting intimate partner violence (IPV) and sexual violence (SV) prevention and response.

Methods

We conducted a systematic search of violence prevention and response mobile phone apps freely available in Apple App Store (iOS; March 2016) and Google Play Store (Android; July 2016). Search terms included violence prevention, sexual assault, domestic violence, intimate partner violence, sexual violence, forensic nursing, wife abuse, and rape. Apps were included for review if they were freely available, were available in English, and had a primary purpose of prevention of or response to SV or IPV regardless of app target end users.

Results

Using the Mobile Application Rating Scale (MARS), we evaluated a total of 132 unique apps. The majority of included apps had a primary purpose of sharing information or resources. Included apps were of low-to-moderate quality, with the overall subjective quality mean for the reviewed apps being 2.65 (95% CI 2.58-2.72). Quality scores for each of the 5 MARS categories ranged from 2.80 (engagement) to 4.75 (functionality). An incidental but important finding of our review was the difficulty in searching for apps and the plethora of nonrelated apps that appear when searching for keywords such as “rape” and “domestic violence” that may be harmful to people seeking help.

Conclusions

Although there are a variety of mobile apps available designed to provide information or other services related to SV and IPV, they range greatly in quality. They are also challenging to find, given the current infrastructure of app store searches, keyword prioritization, and highlighting based on user rating. It is important for providers to be aware of these resources and be knowledgeable about how to review and recommend mobile phone apps to patients, when appropriate.

Published: February 2022

With the relaxing of telehealth regulations through the Health Insurance Portability and Accountability Act (HIPAA) waiver notification for Telehealth Remote Communications during the COVID-19 Nationwide Public Health Emergency, our organization had the opportunity to pilot an innovative virtual care solution using a modified consumer-grade voice-activated video communication system (Amazon Echo Show 8) within one inpatient COVID-19 unit. In this brief report, we describe our experiences with implementing the system and general feedback from clinicians, and discuss areas for future development required to enable future scaling of this solution. Our pilot demonstrates the feasibility of deploying a consumer-grade voice assistant device in COVID-19 patient rooms. We found the devices engaging due to the voice technologies and Alexa functionalities for both clinician and patient entertainment. To enable future deployment at scale, enhancements to the Echo Show and data analytics will need to be further explored.
Therapist-Assisted Web-Based Intervention for Prolonged Grief Disorder After Cancer Bereavement: Randomized Controlled Trial (Preprint)
Authors: Kaiser Julia , Nagl Michaela , Hoffmann Rahel , Linde Katja , Kersting Anette
Published: February 2022

BACKGROUND

Bereavement due to cancer increases the risk of prolonged grief disorder. However, specialized treatment options for prolonged grief after a loss due to illness are still scarce.

OBJECTIVE

The aim of this study is to extend previous findings by evaluating a web-based cognitive behavioral intervention with asynchronous therapist support, consisting of structured writing tasks adapted specifically for prolonged grief after cancer bereavement.

METHODS

The intervention was evaluated in a purely web-based randomized waitlist-controlled trial. Open-access recruitment of participants was conducted on the web. Prolonged grief (Inventory of Complicated Grief), depression, anxiety, posttraumatic stress, posttraumatic growth, somatization, sleep quality, and mental and physical health were assessed on the web via validated self-report measures.

RESULTS

A total of 87 participants were randomized into the intervention group (IG; 44/87, 51%) or the waitlist control group (43/87, 49%). Of the participants, 7% (6/87) dropped out of the study (5/44, 11%, in the IG). Of the 39 completers in the IG, 37 (95%) completed all intervention tasks. The intervention reduced symptoms of prolonged grief (intention-to-treat: P<.001; η2=0.34; Cohen d=0.80) to a clinically significant extent. It had favorable effects on depression, anxiety, posttraumatic stress, posttraumatic growth, and overall mental health but not on somatization, sleep quality, or physical health.

CONCLUSIONS

The web-based intervention for prolonged grief after cancer bereavement is effective in reducing symptoms of prolonged grief disorder and accompanying syndromes in a timely, easily realizable manner and addresses specific challenges of bereavement to illness. Considering web-based approaches in future mental health care policy and practice can reduce health care gaps for those who are bereaved to cancer.

Acceptability of an In-home Multimodal Sensor Platform for Parkinson Disease: Nonrandomized Qualitative Study (Preprint)
Authors: Morgan Catherine , Tonkin Emma L , Craddock Ian , Whone Alan L
Published: February 2022

BACKGROUND

Parkinson disease (PD) symptoms are complex, gradually progressive, and fluctuate hour by hour. Home-based technological sensors are being investigated to measure symptoms and track disease progression. A smart home sensor platform, with cameras and wearable devices, could be a useful tool to use to get a fuller picture of what someone’s symptoms are like. High-resolution video can capture the ground truth of symptoms and activities. There is a paucity of information about the acceptability of such sensors in PD.

OBJECTIVE

The primary objective of our study was to explore the acceptability of living with a multimodal sensor platform in a naturalistic setting in PD. Two subobjectives are to identify any suggested limitations and to explore the sensors’ impact on participant behaviors.

METHODS

A qualitative study was conducted with an inductive approach using semistructured interviews with a cohort of PD and control participants who lived freely for several days in a home-like environment while continuously being sensed.

RESULTS

This study of 24 participants (12 with PD) found that it is broadly acceptable to use multimodal sensors including wrist-worn wearables, cameras, and other ambient sensors passively in free-living in PD. The sensor that was found to be the least acceptable was the wearable device. Suggested limitations on the platform for home deployment included camera-free time and space. Behavior changes were noted by the study participants, which may have related to being passively sensed. Recording high-resolution video in the home setting for limited periods of time was felt to be acceptable to all participants.

CONCLUSIONS

The results broaden the knowledge of what types of sensors are acceptable for use in research in PD and what potential limitations on these sensors should be considered in future work. The participants’ reported behavior change in this study should inform future similar research design to take this factor into account. Collaborative research study design, involving people living with PD at every stage, is important to ensure that the technology is acceptable and that the data outcomes produced are ecologically valid and accurate.

Evaluation of the Dengue Surveillance System in Khyber Pakhtunkhwa Province, Pakistan, in 2020 (Preprint)
Authors: Khan Omar Sharif
Published: February 2022

BACKGROUND

Installation and actualization of a disease surveillance system are prerequisites for early detection of outbreaks. Prompt response is possible when a robust surveillance system is in place. Dengue is one of the many diseases endemic to Pakistan and is potentially fatal.

OBJECTIVE

This study aimed to assess the current dengue surveillance system and its performance and to provide recommendations to stakeholders for its actualization and improvement.

METHODS

A cross-sectional study was conducted in 2020 to document the outcomes. The evaluation was guided by the updated Centers for Disease Control and Prevention guidelines for public health surveillance for the year 2019. A structured questionnaire was designed and piloted to estimate the simplicity, flexibility, acceptability, and stability of the current dengue surveillance system. The sample included 45 provincial- and district-level staff involved in dengue surveillance. Provincial data on dengue were analyzed to evaluate completeness, quality, positive predictive value, sensitivity, and representativeness. Field visits to districts were performed to assess data flow and timeliness.

RESULTS

The reporting rate ranged from 12/100,000 in 2017 to 21/100,000 in 2019, with a total of 7641 reported cases in the province. The mean time of reporting cases was 1 day (range 0-2 days). The simplicity of the dengue surveillance system was at 90% with respect to structure and data flow. The stability of the system was at 84% because of data backup. System flexibility was at 81% and allowed the addition and modification of variables. The average completeness of the selected variables was 65%. About 59% of the staff interviewed considered the system acceptable. Data quality was suboptimal at 48%. The representativeness of the system was at 40%, and it was mainly representative of secondary and tertiary health care hospitals, particularly inpatients. The system positive predictive value for dengue was 15% and sensitivity was 14%, which were below par. The dengue surveillance system can detect dengue outbreaks early.

CONCLUSIONS

An immediate, collaborative, multisectoral, and transdisciplinary plan is needed to enhance reporting from all health facilities. Adequate government funding is needed to improve data quality, and a monitoring mechanism is needed at all levels for prompt functioning of the surveillance system.

Enfoques contextuales dentro de la enseñanza de cultura, literatura y gramática
Authors: Valdivia Ruiz Víctor A. , Meléndrez Cynthia O. , Holguín-Chaparro Carmen Julia
Published: February 2022

En la enseñanza del español como segunda lengua en las universidades de Estados Unidos, es común que el instructor/a se enfrente a barreras lingüísticas, culturales y contextuales que ocasionan que el español y, de manera implícita, sus hablantes se perciban dentro de un continuum que va del prestigio al desprestigio. Dicho fenómeno se vuelve particularmente importante en estados como Nuevo México o Arizona, donde las poblaciones anglo e hispanohablantes conviven habitualmente dentro y fuera del ámbito escolar. Así pues, surge la necesidad de crear planes de estudio adecuados y actualizados que no sólo se preocupen por alcanzar los objetivos lingüísticos y de contenido cultural, sino que también tomen en cuenta las diferentes actitudes hacia la lengua y, especialmente, hagan frente a las de naturaleza negativa. Para ilustrar como hemos abordado esta problemática en la Universidad de Nuevo México, esta presentación describe las bases teóricas y las estrategias mediante las cuales se ha buscado romper con prácticas tradicionales y prescriptivas en la planeación de cursos superiores de cultura, literatura y lengua para los niveles de español 300’s.
Al PCIC se le fue la liebre
Authors: Cruz Iturribarri Sandra Luz
Published: February 2022

El Servicio Internacional de Evaluación de la Lengua Española (SIELE), cuenta con un examen de certificación que se elabora bajo un estricto procedimiento de estandarización en la realización de las tareas que componen el examen, basado en varios documentos entre los que destaca el Plan curricular del Instituto Cervantes (PCIC). Al consultar con frecuencia dicho instrumento, para verificar si el léxico es adecuado para los niveles de A1 a C1 del Marco Común Europeo de Referencia (MCER), se hace evidente una diferencia entre el léxico del español de México y España; además de que hay palabras colocadas en niveles que no corresponden y algunas más, que son fundamentales en la adquisición de nuestra lengua, que no aparecen registradas. En este artículo presento algunas de las diferencias y su propuesta de cambio o de integración del léxico del nivel A1 del PCIC, en relación con el vocabulario de la colección Dicho y Hecho.

El pensamiento latinoamericano en la clase de cultura de E/LE
Authors: Rojas Juan Pedro
Published: February 2022

La formación de profesores de E/LE aborda la dimensión cultural de una forma fragmentaria. Esto impide el desarrollo de una nueva competencia intercultural crítica y reflexiva que salga del simple entrenamiento y se acerque a la idea de interpretación. Para esto se propone en el texto incorporar las reflexiones del Pensamiento Latinoamericano a la formación de profesores de E/LE con el fin de matizar sus conocimientos culturales sin perder de vista su relación con la lengua y los procesos pedagógicos.
Los centros comerciales y su evolución hacia un espacio público/privado en el siglo XX: Plaza Universidad (1968-1969), Plaza Satélite (1970-1971) y Perisur (1979-1980)
Authors: Cruz y González Franco Lourdes
Published: February 2022

Esta investigación analiza tres centros comerciales realizados por los arquitectos Juan Sordo Madaleno y José Adolfo Wiechers, en la Ciudad de México. Se eligieron porque sus propuestas arquitectónicas muestran cómo progresivamente se fueron transformando estos espacios públicos en territorios excluyentes que, sin tener barreras contundentes, están saturadas de mensajes que los anuncian como lugares privados en donde se privilegia al usuario con automóvil sobre el peatón. Asimismo, representan conjuntos en donde se venden primordialmente las mercancías que la sociedad consume en respuesta a la transformación de la vida cotidiana durante la segunda mitad del siglo XX, en relación con el progresivo culto al cuerpo, el hedonismo, el consumismo y la enajenación de la sociedad ante la publicidad.

Published: February 2022

Abstract: Lung cancer is one of the most common and deadly cancers worldwide which can be cured only if it is discovered at an early stage. Lung cancer can be diagnosed using various technologies, including MRI, isotopes, X-rays, and CT. One of the most effective ways to fight cancer is to discover it early enough to significantly improve the patient's chances of survival which can be done by the means of Artificial Intelligence. The proposed approach uses past medical records to determine if the patient has lung cancer. The CT scans are analyzed by a Convolutional Neural Network (CNN) model to determine the stage of cancer. Finally, the suggested model would forecast the patient's estimated medical insurance costs. Machine learning (ML) and Deep Learning (DL) approaches will be used to train and test the models by utilizing open-source datasets. Keywords: Lung Cancer, Computed Tomography (CT) scans, Machine Learning (ML), Convolutional Neural Network (CNN), GoogLeNet.

Published: February 2022

Marketing trends have been increasing in the last few decades. Products need good branding and the right marketing strategy. Various marketing methods have been widely done, and one of them is with the study of neuroscience, especially neuromarketing. Neuromarketing is used to seek the influence of marketing stimuli on consumers and objective data through advances in neurology by utilizing human senses such as restraint, smell, taste, and touch. Measurements of neuromarketing responses to the brain can use electroencephalography signals (EEG). Measurement is done with the visual stimulus of consumers when making decisions. To analyze consumer interests, the majority still using qualitative methods, but it is still considered less effective due to many uncertain factors. In this study, neuromarketing responses were measured to the human brain using (EEG) signal analysis. Data collection was conducted on 11 respondents with a stimulus in the form of different product colors and was affected by changes in light intensity. For pre-processing used bandpass filters to get beta signals in the absence of noise. Then the data will be processed using Fast Fourier Transform (FFT) and energy extraction as characteristic extraction and classification of Support Vector Machines (SVM) in the signal pattern recognition process. The results of testing the best feature combination parameters showed an accuracy value of 72% with a combination of magnitude and phase features. By using the range of phase feature values obtained an accuracy of 67% for signal pattern recognition respondents.

Published: February 2022

Each company applies a contract extension to assess the performance of its employees. Employees with good performance in the company are entitled to future contracts within a certain period of time. In a pandemic time, many companies have made decisions to carry out WFH (Work from Home) activities even to Termination (Attrition) of Employment. The company's performance cannot be stable if in certain fields it does not meet the criteria required by the company. Thus, due to many things to consider in contract extension, we are proposed feature selection steps such as duplicate features, correlated features and Univariate Receiver Operating Characteristics curve (ROC) to reduce features from 35 to 21 Features. Then, after we obtained the best features, we applied into Decision Trees and Random Forest. By optimizing parameter selection using parameter grid, the research concluded that Random Forest with feature selection can predict Employee Attrition and Performance by obtain accuracy 79.16%, Recall 76% and Precision 82,6%.

Authors: Asiimwe Innocent , Pushpakom Sudeep , Turner Richard , Kolamunnage-Dona Ruwanthi , Jorgensen Andrea L. , Pirmohamed Munir
Published: February 2022

Aims: To update our previously reported systematic review and
meta-analysis of observational studies on cardiovascular drug exposure
and COVID-19 clinical outcomes by focusing on newly published randomized
controlled trials (RCTs). Methods: More than 500 databases were searched
between 1-Nov-2020 and 2-Oct-2021 to identify RCTs that were published
after our baseline review. One reviewer extracted data with other
reviewers verifying the extracted data for accuracy and completeness.
Results: After screening 22,414 records, we included 24 and 21 RCTs in
the qualitative and quantitative syntheses, respectively. The most
investigated drug classes were angiotensin-converting enzyme inhibitors
(ACEIs)/angiotensin receptor blocker (ARBs) and anticoagulants,
investigated by 10 and 11 studies respectively. In meta-analyses,
ACEI/ARBs did not affect hospitalization length (mean difference/MD
-0.42, 95% CI -1.83; 0.98 days, n=1183), COVID-19 severity (risk
ratio/RR 0.90, 95% CI 0.71; 1.15, n=1661) and mortality (RR 0.92, 95%
CI 0.58; 1.47, n=1646). Therapeutic anticoagulation also had no effect
(hospitalization length MD -0.29, 95% CI -1.13 to 0.56 days, n=1449;
severity RR 0.86, 95% CI 0.70;1.04, n=2696; and, mortality RR 0.93,
95% CI 0.77;1.13, n=5689). Other investigated drug classes were
antiplatelets (aspirin, 2 trials), antithrombotics (sulodexide, 1
trial), calcium channel blockers (amlodipine, 1 trial) and lipid
modifying drugs (atorvastatin, 1 trial). Conclusion: Moderate- to
high-certainty RCT evidence suggests that cardiovascular drugs such as
ACEIs/ARBs are not associated with poor COVID-19 outcomes, and should
therefore not be discontinued. These cardiovascular drugs should also
not be initiated to treat or prevent COVID-19 unless they are needed for
an underlying currently approved therapeutic indication.

and limbs weakness. Physical examination showed slight cyanosis and cold
limbs. She underwent percutaneous transcatheter closure of a secundum
ASD through femoral vein eight months before. On further investigation,
transthoracic echocardiography (TTE) revealed severe tricuspid
regurgitation and the migrated ASD device (Figure 1), and the
embolization seemed to be located near the left ventricular inflow
tract. Computed tomography (CT) and three-dimensional reconstruction
confirmed the left-side migration of the device, and revealed
obstruction of RPV caused by the embolization (Figure 2).
In vivo and in silico screening for antimicrobial compounds from cyanobacteria
Authors: Lenz Selina , Strieth Dorina , Ulber Roland
Published: February 2022

Due to the emerging rise of multi-drug resistant bacteria, the discovery
of novel antibiotics is of high scientific interest. Through their high
chemodiversity of bioactive secondary metabolites, cyanobacteria have
proven to be promising microorganisms for the discovery of antibacterial
compounds. These aspects make appropriate antibacterial screening
approaches for cyanobacteria crucial. Up to date, screenings are mostly
carried out using a phenotypic methodology, consisting of cyanobacterial
cultivation, extraction, and inhibitory assays. However, the parameters
of these methods highly vary within the literature. Therefore, the
common choices of parameters and inhibitory assays are summarized in
this review. Nevertheless, less frequently used method variants are
highlighted, which lead to hits from antimicrobial compounds. In
addition to the considerations of phenotypic methods, this review
provides an overview of developments in the genome-based screening area,
be it in-vivo using PCR technique or in-silico using the recent
genome-mining method. Though, up to date these techniques are a lot less
applied than phenotypical screening.

“Community of Interests” The Creation, Development and Challenges of the Science Faculty at the University College of Swansea, circa 1920 – 1970
Authors:   , Thomas Karmen
Published: February 2022

This thesis addresses the development of the science faculty at the University College of Swansea from its creation in 1920 to 1970 through the progression of the science departments, the scientific curriculum, and research. While the timeline of the thesis is concentrated in the twentieth century, there is an initial investigation into nineteenth century university curriculum reform to clarify the link to later scientific educational developments and academic relationships with industry and commerce. This thesis argues that it was a framework of communities with its attendant roles of collaborations and networks which supported and shaped academic development both within the institution and in external spaces of influence. The expansion of these communities enabled the growth of the institution’s industrial, commercial, and academic connections at a regional, national, and transnational level. At the core of this research is the previously uncatalogued primary source material which provided an invaluable insight into decades of challenges, reactions, and relations of the individuals of the science faculty’s communities. Furthermore, to place the institution’s academic developments in a wider historical context an interdisciplinary approach was taken using the fields of educational, industrial, and cultural histories accompanied by political and military studies. By using this approach, the thesis determines how well the university college adapted to the challenges of delivering a comprehensive programme of science modules during adverse financial and unfavourable political periods, notably the depression of the 1930s and World War II. In addition, the thesis asserts that the post-war modernisation of the science faculty’s infrastructure was an essential element in ensuring that the University College of Swansea responded positively to the demands of delivering modern academic scientific teaching and research.
