Authors: Baydhowi . , Purwono Urip , Siswadi Ahmad Gimmy Prathama , Ali Moondore Madalina
Published: March 2022

Background:

National identity is an important concept to be developed, so it is necessary to have a measurement instrument that have evidence of validity and reliability. Thus, the accuracy of the information obtained through measurement of this instrument will be guaranteed.

Objective:

This article aims to examine the psychometric property of the national identity scale to fulfill the standardization of accurate measurement.

Methods:

In this study, three analytical approaches were used, those are content validity involving eight subject matter experts (SME), confirmatory factor analysis (CFA) and reliability analysis. For the reliability and CFA approach, 300 students were used as samples who were taken through convenience sampling technique.

Results:

The results of the analysis show that out of the 20 items compiled in the content validity analysis, one item is inadequate because it has a below standard score on Aiken's coefficient of validity. This one item then revised again to be included in the tryout and data collection for the next stage of analysis. The results of the CFA analysis show that the model and data are fit and there are two inadequate items, while the contribution of the three factors on the national identity scale is significant. In the third analysis, it was found that an adequate coefficient reliability had an effect on the low Standard Error of Measurement (SEM).

Conclusion:

Based on the results of the analysis, it can be concluded that the Indonesian national identity scale has fulfilled good psychometric properties. It can be proven from evidence validity base on content, confirmatory factor analysis (CFA) and reliability analysis.

Suitability of the Unified Theory of Acceptance and Use of Technology 2 Model for Predicting mHealth Acceptance Using Diabetes as an Example: Qualitative Methods Triangulation Study
Authors: Schretzlmaier Patrik , Hecker Achim , Ammenwerth Elske
Published: March 2022

Background

In recent years, the use of mobile health (mHealth) apps to manage chronic diseases has increased significantly. Although mHealth apps have many benefits, their acceptance is still low in certain areas and groups. Most mHealth acceptance studies are based on technology acceptance models. In particular, the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model was developed to predict technology acceptance in a consumer context. However, to date, only a few studies have used the UTAUT2 model to predict mHealth acceptance and confirm its suitability for the health sector. Thus, it is unclear whether the UTAUT2 model is suitable for predicting mHealth acceptance and whether essential variables for a health-related context are missing.

Objective

This study aims to validate the suitability of UTAUT2 for predicting mHealth acceptance.

Methods

In this study, diabetes was used as an example as mHealth apps are a significant element of diabetes self-management. In addition, diabetes is one of the most common chronic diseases affecting young and older people worldwide. An explorative literature review and guided interviews with 11 mHealth or technology acceptance experts and 8 mHealth users in Austria and Germany were triangulated to identify all relevant constructs for predicting mHealth acceptance. The interview participants were recruited by purposive sampling until theoretical saturation was reached. Data were analyzed using structured content analysis based on inductive and deductive approaches.

Results

This study was able to confirm the relevance of all exogenous UTAUT2 constructs. However, it revealed two additional constructs that may also need to be considered to better predict mHealth acceptance: trust and perceived disease threat.

Conclusions

This study showed that the UTAUT2 model is suitable for predicting mHealth acceptance. However, the model should be extended to include 2 additional constructs for use in the mHealth context.
Lessons for Uptake and Engagement of a Smartphone App (SURE Recovery) for People in Recovery From Alcohol and Other Drug Problems: Interview Study of App Users (Preprint)
Authors: Neale Joanne , Bowen Alice May
Published: March 2022

BACKGROUND

Mobile health apps promoting health and well-being have substantial potential but low uptake and engagement. Barriers common to addiction treatment app uptake and engagement include poor access to mobile technology, Wi-Fi, or mobile data, plus low motivation among non–treatment-seeking users to cut down or quit. Working with people who used substances, we had previously designed and published an app to support recovery from alcohol and other drug problems. The app, which is available for free from the Apple App Store and Google Play, is called SURE Recovery.

OBJECTIVE

The aim of this paper is to undertake a qualitative study to ascertain end users’ views and experiences of the SURE Recovery app, including how it might be improved, and present the findings on uptake and engagement to assist other researchers and app developers working on similar apps for people experiencing alcohol and other drug problems.

METHODS

Semistructured telephone interviews were conducted with 20 people (n=12, 60%, men and n=8, 40%, women aged 25-63 years; all identifying as White British) who had varied patterns of using the app. The audio recordings were transcribed, and the data were coded and analyzed through Iterative Categorization.

RESULTS

Analyses identified three main factors relevant to uptake (discoverability of the app, personal relevance, and expectations and motivations) and three main factors relevant to engagement (the appeal and relevance of specific features, perceived benefits, and the need for improvements). The findings on uptake and engagement were largely consistent with our own earlier developmental work and with other published literature. However, we additionally found that uptake was strongly affected by first impressions, including trust and personal recommendations; that users were attracted to the app by their need for support and curiosity but had relatively modest expectations; that engagement increased if the app made users feel positive; and that people were unlikely to download, or engage with, the app if they could not relate to, or identify with, aspects of its content.

CONCLUSIONS

Incorporating end-user views into app design and having a network of supportive partners (ie, credible organizations and individuals who will champion the app) seem to increase uptake and engagement among people experiencing alcohol and other drug problems. Although better digital literacy and access to devices and mobile data are needed if addiction recovery apps are to reach their full potential, we should not evaluate them based only on observable changes in substance use behaviors. How using an app makes a person feel is more transient and difficult to quantify but also relevant to uptake and engagement.
Menstrual Irregularities Post COVID-19 disease/vaccination in Indian Population: An Observational Study (Preprint)
Authors: Moolamalla Sreeja , Bakshi Kavitha , M Vijayasree
Published: March 2022

BACKGROUND

Menstrual changes reported in various studies post-COVID-19 vaccination were diverse, ranging from increased bleeding to the cessation of bleeding. Women’s health has long been neglected in biomedical research. Unfortunately, clinical trials of the current COVID-19 vaccines did not collect menstrual cycle outcomes post-vaccination. The authors conducted the following study on the impact of the disease and vaccination on menstruation.

OBJECTIVE

Increased reporting of menstrual disturbances post-vaccination and inadequate inclusion of questions about menstruation in vaccine trials and disease progression studies have been the baseline for conducting this study. We aim to assess the influence of vaccines and COVID-19 disease on menstruation and identify patterns, if any, in cycles post disease/vaccination.

METHODS

A Multicenter observational study was performed using a questionnaire-based survey via an online link. The participants who filled out the survey were predominantly 21-25-year-olds (80%). Participants with prior menstrual irregularities were eliminated from the study.

RESULTS

The prevalence of unusual menstrual cycles post-vaccination/infection was 21.7%.17.11% experienced changes post-vaccination and 22.8% of the infected individuals reported abnormalities post-COVID-19 disease. A substantial increase in dysmenorrhea was reported(p < 0.001) post-vaccination/infection. An increase in menstrual flow was observed in 14.9% post-vaccination and 23.9% post-infection.

CONCLUSIONS

Menstrual changes post-vaccination were insignificant; however, significant differences in menstruation were reported post-infection. The study strengthens the association between COVID-19 and menstruation and urges the inclusion of menstrual health in disease intervention studies.

Published: March 2022

The increase of hypertension sufferers encourage the development of functional foods. The presence of tempeh mixed grains of soybean and jackbean contains bioactive peptides as antihypertensive and antioxidant agents encourage the development of functional food such as tempeh flour of mixed grains. The research was aimed to investigate the effect of temperature and drying time on functional properties, asam amino acid profile, and isoflavone compounds. The different drying temperatures (50oC and 70oC) and drying time  (6; 8; and 10 h) were applied on soybean and jackbean tempeh (1:1) w/w) for making the mixed grains tempeh flour. The Angiotensin Converting Enzyme (ACE) inhibitor activity, antioxidant activity, and total phenolic, amino acids profile, and isoflavone content of the flour were analyzed. The result showed that the best tempeh flour of mixed grains was obtained by drying at 70°C for 8 h with ACE inhibitor activity of 86.04%, antioxidant activity of 55.34% and total phenolic of 3.98 mg/g DB. This flour contained amino acids related to ACE-Inhibitor peptide precursors (glutamic acid and leucine), antioxidant peptide precursors (phenylalanine and histidine) as well as isoflavone compounds (daidzein and genistein). This finding reveals that drying temperature and time affected the functional properties, amino acids profile and isoflavone compounds.

Authors: Boussaa Faten , Zaouay Faten , Mars Messaoud
Published: March 2022

Physicochemical and microbiological properties changes of new beverages combining sour (‘Garoussi 2’, ‘Mezzi 1’, ‘Mezzi 2’) and sweet (‘Gabsi’, ‘Tounsi’) pomegranate juices with different proportions (10% and 20% of sour juices) were studied over a 14 days refrigerated storage. The sour juices have proved to be very rich in total soluble solids, total anthocyanin and total phenolic contents. However, these juices are not appreciated by panellists because of high acidity content. The juice blends were characterized by an attractive red colour, acceptable acidity, higher total soluble solids content, higher total phenol and anthocyanin contents compared to sweet juices. The juice blending was found to be very effective in reducing the browning and improving the appearance of beverages during storage.  High microbial loads of juice samples stored up to 14 days indicate their poor microbiological quality. The beverage based on Gabsi and Garoussi 2 (10 % and 20 % proportions) presented better nutritional and microbiological stability during storage leading to their high consumer acceptance. It was concluded that conservation of juice samples should not exceed 7 days in order to have healthy value-added beverages.

Published: March 2022

Abstract: Self - compacting concrete (SCC) is a high - execution concrete that can stream under its own load to totally fill the structure work and self-unites with next to no mechanical vibration. Such concretes are a speed up for the placement, to lessen the work prerequisites required for combination, getting done and wipe out ecological contamination. This will guarantee that the concrete acquired has great stream capacity, self-compacting capacity and other wanted SCC properties.Self-compacting concrete is a kind of concrete that gets under its self-weight. Self-compacting concrete is a type of concrete that gets under its self-weight. It is commonly abbreviated as the concrete. Which can placed and compacted in to every corner of a formwork; purely means of its self-weight by eliminating the need of either external energy input from vibrators or any type of compacting effort. There is a current trend in all over the world to utilize the treated and untreated industrial By-products, domestic wastes etc. as raw materials in concrete. These not only help in the reduce of the waste materials but also create a cleaner and greener environment. This report demonstrates the possibilities of using saw dust as partial replacement of fine aggregate in concrete. This experimental investigation was performed to evaluate the strength and durability properties of M25 and M30 grade of self compaction concrete, in which fine aggregate was partial, replaced with saw dust waste. Fine aggregate was replaced with four percentage (0%, 10%, 20%, 30%) of saw dust waste by weight. Fresh properties of self-compacting concrete were studied. Compression test and splitting tensile strength test were carried out to evaluate the strength properties of concrete at the age of 7, 14, and 28 days. Keywords: Self-compacting concrete (SCC), Saw dust, strength and durability properties of concrete, Compression test and splitting tensile strength test.

PARLAMENTAR
Authors: Fuentes-Hernández Pablo , Cerda-Brintrup Gonzalo
Published: March 2022

"Parley is the voice that describes the action of discussing an issue and involves the primary intention of finding a solution. In other words, one parleys to reach agreements, to be on the same page. In this act, one party must concede to the other that their arguments are of interest for the debate, that they are pertinent, appropriate, necessary. Likewise, this is an act that is done informally, that does not have an official character, even when it comes from a representative authority. Thus, one parleys among equals. Over recent years, and almost everywhere, we have seen countless ideological, social, economic confrontations inspired by arguments that are backed by an apparent reason, the assumed common good. The idea of imposing our arguments over others, based on demonstrations of different nature, sometimes simply discretionary and even authoritarian, have led to that what used to be conceived as freedom of choice, often becomes freedom of decision, whereby useless, arrogant, haughty authoritarianism ends up being put into place, expressed from tight one-way windows which, in the end, come from partial views."
Desarrollo de la industria siderúrgica y arquitectura de vanguardia del siglo XX en Chile: La Unidad departamental Acería CONOX y Colada Continua (1976), y Central de Alimentación y Casino (1973) en la usina de CAP-Huachipato, como ejemplos del paradigma brutalista
Authors: Vargas-Rojas Neftalí , Bisbal-Grandal Ignacio
Published: March 2022

The Huachipato steel plant located in San Vicente Bay, Talcahuano, was set in motion in the mid-20th century as a state initiative (personified in CORFO), to create a national production center in the Bío-Bío area and to promote economic and social development, in response to the 1930 crisis and the Chillan earthquake, in 1939. Within the first decades of operation, the Compañía de Acero del Pacífico (CAP) implemented a series of expansion plans to improve and increase production, modernizing machinery and constructing buildings to accommodate both the new industrial processes and the service equipment that the workers would use. In this context, in the 1970s, two buildings of notable architectural quality were built: the Unidad Departamental Acería CONOX y Colada Continua, and the Central de Alimentación y Casino de Trabajadores. In this study, the information available in Revista AUCA (1979), where said projects are published, was collected, and later the characteristics of these buildings were analyzed, highlighting their values as architectural work -morphological, spatial, aesthetic, structural-, reviewing the theoretical foundations and the relationship with other key architectural works, to understand the concepts of “brutalism” and “mat building”. In summary, the results reflect that these works, on adapting to functions that are so different to each other, as the industrial production and workers’ facilities) are, reflect the modern paradigm of 1959’s X CIAM and the design criteria of the architectural avant-garde of the 1960’s, becoming both industrial heritage and architectural heritage of Chile.
Cocriação: colaborações emergentes ibero-americanas em arquitetura e manufatura digital
Authors: García-Alvarado Rodrigo , Henriques Gonçalo Castro , Chiarella Mauro
Published: March 2022

Innovative technologies for digital design and manufacture have spread with globalization, providing improved working tools and processes for architecture. These technologies open up different professional opportunities, forging alternative relations with society, especially for new generations and emerging countries. This article reflects on novel collaborative experiences between Ibero-American Universities, accounting for the intensive use of digital technologies in architecture. To bridge technological gaps, the authors describe collaborative efforts to produce full-size constructions, using networking, which results in a hybridization of these “new media” adapted to local and cultural contexts. These initiatives arise from an attempt to overcome the lack of resources at local Universities and their rigid institutional processes, along with their concerns about promoting global connectivity for new generations, leading to informal and collective actions that break with traditional teaching, applying advanced techniques in unseen collective and creative processes. These experiences reveal an architectural work distributed among all the participants that collaborate in the conceptualization, programming, management, and execution of the design, with diverse hybrid practices, and a powerful collective synergy. This also results in new expanded proposals that unfold new relationships with the environment and the community. Thus, these actions tend, by themselves, to integrate and project new horizons in architectural collaboration. This article aims at mapping these spatial-temporal actions in Architecture from the global south (Santos 2014).
Scientific research in news media: a case study of misrepresentation, sensationalism and harmful recommendations
Authors: Dempster Georgia , Sutherland Georgina , Keogh Louise
Published: March 2022

Accurate news media reporting of scientific research is important as most people receive their health information from the media and inaccuracies in media reporting can have adverse health outcomes. We completed a quantitative and qualitative analysis of a journal article, the corresponding press release and the online news reporting of a scientific study. Four themes were identified in the press release that were directly translated to the news reports that contributed to inaccuracies: sensationalism, misrepresentation, clinical recommendations and subjectivity. The pressures on journalists, scientists and their institutions has led to a mutually beneficial relationship between these actors that can prioritise newsworthiness ahead of scientific integrity to the detriment of public health.

Authors: Rexha Donat , Ziberi Besime , Alban Hetemi , Gorda Eda
Published: March 2022

This study aims to analyze the mechanisms of active labour market policy in the case of Kosovo and the impact on reducing the unemployment rate and increasing employment. This research is descriptive, analytic, and exploratory. The data used are secondary data in the quarter for the period 2016–2020, which are provided by the Kosovo Agency of Statistics. The study uses the OLS (ordinary least square) econometric model and Pearson correlation in order to assess the impact of unemployment and employment rate on Kosovo’s GDP (gross domestic product). The paper concludes that Kosovo has approved a large number of programs for the activation of the unemployed, mainly young people, but generally young university graduates are in a higher structure and rate in the composition of the unemployment rate. It is generally accepted that university graduates as workforce are the key driver of economic growth and development (Ziberi, Rexha, & Ukshini, 2021). This allows us to come up with further recommendations, such as the active policies in labour market in the case of Kosovo to be designed in the future based on a cost-benefit perspective and in order to measure their effectiveness

Establishment of rainfall partitioning parameters for Tea
Authors: Shukla Chitra , Tiwari K.N. , Mishra Surendra
Published: March 2022

Tea is a popular cash crop in Asian and African countries that can be
grown from tropical to subtropical climates with high humidity and heavy
rainfall. India is the second-largest producer of Tea worldwide, having
approximately 567 thousand hectares under tea cultivation.
Interestingly, rainfall partitioning parameters (i.e., throughfall (TF),
stem flow (SF) and interception (IC)) for Tea plantation do not appear
to have been investigated. Therefore, this study aims to experimentally
monitor TF, and SF for Tea. For this study, a Tea plantation of nearly
27-year-old grown in an area of 1.3 acres at the experimental farm of
IIT Kharagpur campus, West Bengal, India was selected. IC was derived
from the in-situ measured TF and SF values, against the 106 nos.
rainfall events (RE) recorded during 2017-2018. RE depth varied from 3
mm- 60 mm with a coefficient of variance (CV) of 84%. However, relative
portion of rainfall as TF (TF%), SF (SF%), and I (IC%) varied from
59-89%, 0.1-2%, 10%-40% with CV as 10%, 29% and 27%,
respectively. Thus, the portion of rainfall that reaches SF was
insignificant (≤2%) than TF. Therefore, SF can be omitted considering a
negligible portion, and IC can be derived directly from TF for Tea
plantation. Average values of TF and IC were obtained as 72% and 27%
of incident R. Furthermore, the response of all these partitioning
parameters were analyzed against RE characteristics such as RE depth,
intensity, and duration. These results are the first of their kind in
respect of TF, SF, and IC values for Tea plantation besides being also
consistent with those reported elsewhere for other plantations, and are
useful for pragmatic applications.
Chemical Mechanism and Atmospheric Degradation of C4F9N initiated by OH Radical: Ab Initio Kinetic Exploration
Authors: Zhao Jun , Wang Yongjin , Zhou Biao , Bian Huiting
Published: March 2022

This work presents a thoroughgoing theoretical study on the OH-initiated
combustion chemical kinetics and atmospheric degradation of C4F9N by
employing high-level quantum chemical methods and RRKM/master-equation
theory. All the stationary points on potential energy surface were
cautiously investigated at B3LYP/6-311++G(d,p) level for geometry
optimizations, and thereby their single-point energies were refined by
applying CCSD(T)/6-311++G(d,p) method. Based on quantum calculations,
kinetics and branching ratios for the major channels were predicted
within 300-3000 K and 0.01-100 atm by solving the RRKM/master-equations.
The addition of OH to C4F9N generating M1 dominates the overall kinetics
at low temperatures. Subsequently, its two β-scission channels of C-C
bonds forming CF3CF2N=CF(OH)+CF3 (P8) and CF2=NCF(OH)CF3+CF3 (P9) become
competitive and play a lead role in whole C4F9N+OH system at the
corresponding high temperatures and elevated pressures. The formation of
CF3 radical prompts two routes to potentially have the significant
contribution to flame inhibition in actual applications. Additionally,
the complex degradation pathways of C4F9N were also looked into by
successively reacting with various oxides, including OH, O2, NO, HO2, to
finally generate the removal products CF3CF2N(OOH)CF(OH)CF3 (Pd2),
CF3CFO (Pd3-2), and CF3CF2NO (Pd4). The atmospheric lifetime of C4F9N is
evaluated as 72 years regarding to one step addition between C4F9N and
OH radical.
Multi-proxy (CFCs, Cl, δ18O and δD) assessment of the origin, residence time and recharge of groundwater in the Bilate River basin (BRB) of southern main Ethiopian rift (SMER)

The volcanic aquifer of Bilate river basin (BRB) that situated on the
southwestern side of the MER serve as sole reservoir of water supply for
urban and rural people found in the basin. This study investigates
residence time and groundwater recharge process in the Bilate river
basin. For the first time, this research work delivers information on
the resident time and groundwater recharge on the basis of multi tracer
approach (CFC’s, Cl, δ O and δD). The δ
O and δD value of groundwater found in the range of
-4.9 to -1.1‰ and -31 to 5.3‰, respectively. It is shown that stable
isotopic value of groundwater drawn along or close to AAMWL and GMWL,
indicates that groundwater recharge is of meteoric origin. The
groundwater of BRB volcanic aquifer comprises substantial amount of CFCs
concentration. It is observed from CFC data that the oldest component of
groundwater was recharged prior 1950, while the younger component
recharged in different time as of 1950. The relation found between CFC’s
indicates that groundwater comprise mainly of binary mixture with young
groundwater in the age of 20-25-year-old and that of groundwater older
than 60 years. The fraction of young water in the groundwater ranges
from 0.134 to 0.89 and shows decreasing trend from highland towards the
rift. CFC-113 is conservative in the system and used to determine
groundwater lifetime in the Bilate river basin that ranges from 26 to 63
years. The conservative chloride method i.e. chloride mass balance
employed to Bilate river basin calculated yearly average groundwater
recharge to be 219 mm/y which accounted for 21% of the mean annual
areal rainfall. This research can help us better understand how
groundwater circulation and recharge mechanism works, as well as how
long groundwater stays underground in the complex hydrogeological
setting of rift volcanic aquifer.

Published: March 2022

The isohydric-anisohydric continuum describes the relative stringency of
stomatal control of leaf water potential ( ψ)
during drought. Hydroscape area ( HA) – the water potential
landscape over which stomata regulate ψ –
has emerged as a useful metric of the iso/anisohydric continuum because
it is strongly linked to several hydraulic, photosynthetic, and
structural traits. Previous research on HA focused on broad
ecological patterns involving several plant clades. Here we investigate
relationships of HA to climatic conditions and functional traits
across ecologically diverse but closely related species while accounting
for phylogeny. Across a macroclimatic moisture gradient, defined by the
ratio of mean annual precipitation to mean annual pan evaporation (
P/E), HA decreased with
P/E for ten Eucalyptus species. Greater
anisohydry reflects lower turgor loss points and greater hydraulic
safety, mirroring global patterns. More isohydric species have mesophyll
photosynthetic capacity that is more sensitive to
ψ, consistent with an earlier model for
optimal stomatal behavior. Hydroscapes exhibit little plasticity in
response to variation in water supply, and the extent of plasticity does
not vary with P/E of native habitats. These
findings strengthen the case that HA is a useful metric for
characterizing drought tolerance and water-status regulation.
Evaluating Indonesia's Presumptive Tax Policy on Accountant Professional Services

Published: March 2022

There is no disagreement about accountants' expertise in bookkeeping. Initially, the assumed tax policy was meant to alleviate bookkeeping requirements for small and medium-sized businesses that were unable to do so. However, why does the accounting profession benefit from not performing bookkeeping if it has a specific gross revenue? This issue encourages authors to evaluate Indonesia's presumptive tax regulations for accountants' professional services. The objectives of this research are to ascertain why accountants employ Net Income Calculation Norms to determine their income taxes, to assess presumptive tax policies through the perspective of tax collection principles, and to explore more suitable presumptive tax policies for the accounting profession. This study applies a qualitative method, collecting data through in-depth interviews. The findings indicate that the accounting profession's presumptive tax policy fulfills the concept of ease of administration for taxpayers but not the principle of substance over form or revenue productivity. The government should deregulate the policy of Net Income Calculation Norms for Accountant Professional Services so that it maintains consistency with the policy objective of providing presumptive taxation to taxpayers with a certain gross sale.
