Background: Worm infestation is a major public health problem. It has been estimated that more than 25% of the world’s population are infected with worms, with the major incidence occurring in developing countries. Worm infestation can be prevented by practices such as safe disposal of excreta, washing hands after defection, wearing slippers and food hygiene, washing vegetables and fruits properly before using. These can be implemented through effective education of mothers because the mother is only the person who provides the proper education to their children. Objectives: 1. To assesses the existing knowledge regarding helminthic infestations among the mothers of under- five children. 2. To evaluate the effectiveness of structured teaching programme on knowledge regarding helminthic infestation among the mothers of under- five children. 3. To determine the association between pre-test knowledge scores regarding helminthic infestations among the mothers of under five children with selected sample characteristics. Methodology: The research design used for this study was pre experimental, one group pre-test post-test design. The study was conducted at St. Philomena’s hospital in Bengaluru, Karnataka. The sample size selected for this study consists of 30 mothers of under- five children. Non- probability purposive sampling technique was used to select the samples. The tool used in this study was socio-demographic profile and structured knowledge questionnaire. Result: In the pre-test, none had adequate knowledge, whereas 11 (36.6%) samples had moderate knowledge and 19(63.4%) of them had inadequate knowledge. In the post-test, 9(30%) samples had adequate knowledge, whereas 21 (70%) samples had moderate knowledge and none of them had inadequate knowledge. The mean post- test knowledge (24) score was higher than the mean pre-test (12.5). The scores predicted the significant difference (11.5) at p<0.05 level. The calculated “t” value was (14.66) at p <0.05 level of significance, which indicated the significant difference in the level of knowledge before and after the implementation of structured teaching program. Among socio-demographic variables; occupation of mother, type of family and source of information had association with the pre-test knowledge scores of mothers of under- five children. Conclusion: From the findings of the study, it was concluded that the structured teaching programme regarding helminthic infestations was effective in improving the knowledge among the mothers of under- five children.

The experiment was conducted at Biochemistry Section, Ayub Agricultural Research Institute, Faisalabad Pakistan, during the year 2017-18 to assess the total phenols and antioxidants potential of mango, grapes, banana, guava, mulberry, strawberry, loquat, melon, apricot and phalsa. Fruits samples were obtained from the market of Faisalabad Pakistan, washed, dry at room temperature, extracted their juice/pulp. The juice was stored at 4 °C for further analysis. Juice samples were processed for Vitamin- C, pH, TSS, total phenolics and total antioxidant capacity. The results showed that among all the ten fruits vitamin C was higher in mango (24.33 mg/100 mL) followed by phalsa (19.74 mg/100 mL) and Grapes (11.25 mg/100 mL), whereas lower value was observed in melon (3.3 mg/100 mL) and loquat (3.4 mg/100 mL). Vitamin C for other fruits lies between these. Highly acidic pH of fresh juices of all the fruits was observed except in melon (5.82) and guava (5.38) which is less acidic. Percentage of TSS was higher in phalsa, mulberry and mangoes (13.8, 13.5 and 13.9% respectively) and lesser in melon (5.6%). Antioxidant capacity (% DPPH reduction) was found higher in grapes (91.9%) and mango (91.2%) which was statistically at par with melon (90.9%), while lesser value was observed in mulberry (51.6%). Total phenolics were significantly higher in grapes (1266.4 µg GAE/mL), whereas minimum phenolic contents were found in melon (4.1 µg GAE/mL). Therefore, it was concluded that grapes are more nutritious and healthy fruit than other.

Published: March 2022

Education, identified as the substratum of any serious nation’s growth and development, is regarded as an instrument for social change, as well as the process of preparing an individual to become a functional and acceptable member of society. It also ensures the character and moral development of the young learners and the development of sound attitudes for both genders. This study examined gender differentials in educational attainment in rural Nigeria, employing the t-test, analysis of variance and the ordinary least squares regression model for analysis. The main factor which had negative effects on educational attainment of female-headed households was the cost of schooling while factors such as the organization running the school and means of transportation had positive effects on the educational attainment of female households. On the other hand, while age and occupation of the household head had negative effects on male educational attainment, factors such as the value of asset, the organization running the school and means of transportation had positive effects. The approval and implementation of necessary legislation and policies on education targeted at rural dwellers is of utmost importance. This could center on the provision of more nearby government-owned schools as well as awareness creation on the essence of educating both genders, especially the girl child, with a focus of achieving gender balance in educational attainment.

The higher the spiritual health scores, the higher the scores of the spiritual care behavior. Furthermore, the spiritual health status of nursing staffs in the medical wards can significantly predict their spiritual care behaviors.

Conclusion/Clinical Implication: This study suggests adding strategies of spiritual care and spiritual care behavior for nursing education, clinical nursing, and nursing administration. In doing so, the spiritual health status and spiritual care behaviors of clinical healthcare professionals could be promoted, thus affecting the quality of spiritual care in holistic care settings.

 
Reforma electoral y posconflicto en Colombia: tensiones, avances y tareas pendientes tras la firma del Acuerdo de Paz (2016-2020)
Authors: Pérez Guevara Nadia , Uribe Mendoza Cristhian , Acuña Villarraga Fabián
Published: March 2022

Este artículo analiza las propuestas de reforma electoral que se han discutido en Colombia tras la firma del Acuerdo de Paz entre el gobierno y la guerrilla de las FARC-EP en 2016, y examina las tensiones, los avances y las tareas pendientes frente a la modernización del sistema electoral colombiano. Para ello, se emplea como evidencia empírica los documentos oficiales de la Presidencia de la República, la Misión Electoral Especial, el Consejo Nacional Electoral y la Registraduría Nacional del Estado Civil. Se concluye que las élites nacionales no han tenido voluntad política para aprobar una reforma política integral al sistema electoral colombiano, especialmente, en lo que atañe a dimensiones, como la autoridad electoral, el financiamiento público o las listas cerradas. No obstante, los cambios constitucionales y normativos derivados de la implementación del Acuerdo Final han favorecido la inclusión de nuevos actores en el sistema político.

Authors: Moturi Edna Kwamboka , Horton Katherine , Bell Leila , Breakwell Lucy , Dueger Erica
Published: March 2022

Member States in the Western Pacific Region (WPR) of the World Health Organization (WHO), are highly vulnerable to emerging influenza viruses that have the potential to cause global pandemics. A well-coordinated strategy for preparedness is required at national and international levels for a robust response and to mitigate the potentially dire consequences of the next influenza pandemic. Of 37 countries and areas in the region, 23 have publically available national pandemic influenza preparedness and response plans; of these, only 17% have been updated in the last five years. However, many plans are pending update and may benefit from integrating some components of the 2017 WHO pandemic influenza risk management guide. Additionally, many plans need to be operationalized to test their functionality. Since 2007, WPRO has conducted annual PanStop exercises to test pandemic containment plans and RC mechanisms in a simulated environment that imitates pandemic events as they unfold. PanStop exercises provide an opportunity for countries to validate policies, protocols and procedures involved in implementing rapid containment (RC) operations, and to identify strengths and opportunities for improvement in planning activities for pandemic influenza. By participating in exercises such as PanStop and the annual regional International Health Regulation (IHR) Crystal Exercise, and subsequently adapting national preparedness plans based on exercise outcomes, WPR continues to improve readiness for the next influenza pandemic.

Collaborative Leadership in an Organizational Context: A Research Agenda
Authors:   Pan Africa Christian University, Ang’ana Gilbert A. , Kilika James M. ,   Kenyatta University
Published: March 2022

Organizations not only exist to make a profit and be financially sustainable but also to make a difference and have a meaningful legacy using specific business models adopted. To achieve that outcome organizations must establish effective authority relationships to work together efficiently. This is what entails collaborative relationships and leadership. The literature on collaborative leadership despite having significant developments over the last two decades has been faulted. There have been vast perspectives from scholars with minimal consensus on what constitutes acceptable dimensions of collaborative leadership and how that fits in an organizational context. These misalignments have resulted in challenges to the full realization of the benefits of collaborative leadership as a result of its skewed implementation and application in an organizational context. The result is a lack of appreciation and belief by business practitioners and organization leaders on the implications of collaborative leadership application on their organization’s financial sustainability. This effect goes deeper in that organization leaders are not very clear on the impact of their organization's business model and their role in facilitating successful collaborative leadership. This conceptual paper aimed to bridge that gap by reviewing and integrating extant conceptual, theoretical, and empirical literature on collaborative leadership and present a case for the development of a new theoretical model suitable for the expansion of the current understanding of deployment of collaborative leadership in an organizational context. The paper reviewed 397 articles from various journals, which were searched through the google search engine. 132 articles were finally used in the development of this paper sieved by the year of publication from 2001-2021. The findings lead to the development of a proposed and integrated conceptual framework model linking collaborative leadership to financial sustainability as an organizational outcome while acknowledging the significance of the role played by the organization’s business model and top echelon support in the relationship. Several propositions are presented for consideration and validation through empirical work. The study calls on future research to consider the adoption of the proposed model in extending research on leadership to new frontiers.

Authors: A Vásquez Azofeifa
Published: March 2022

The objective of this research is to identify the main factors of psychological risk presented by officials who have worked under the modality of teleworking, during the first semester of the Covid-19 pandemic. The methodology developed for this research was created out from a positivist paradigm, a quantitative approach, an exploratory character and with a non-experimental method. The tool applied CoPsoQ -istas21 provides the levels of psychosocial risk in people who work under the teleworking modality, however, it does not determine the origin of the risks, since the scope of the investigation has a sole purpose of diagnosis. According to the results obtained, it can be considered that the main psychosocial risk factors as a consequence of teleworking are the dimensions of the pace of work, quantitative requirements, emotional, double presence, employment insecurities and working conditions. The job positions exposure prevails greater risk in technical positions, while executives present a moderate risk of exposure. Finally, the exposure by sex is greater in women, mainly in the demands of predictability, insecurity about employment and insecurity about working conditions. In conclusion, there is evidence of psychosocial risks factors for health, mainly in the group of psychological demands of work, in addition, the dimensions of greater risk could be influenced by the Covid-19, which has cause insecurity as a result of unemployment worldwide.

Authors: Jin Chenxuan
Published: March 2022

Objectives: The purpose of this study is to evaluate the accuracy of 3D printed burnout resin, CAD/CAM milled wax and CAD/CAM PMMA and the effect on die spacing and cementation onto the tooth. Method: Design and manufactured three different type of digital materials, PMMA, milled wax and 3D printed burnout resin (n=4/product). PMMA and milled wax were milled by MC X5 CAD/CAM machine and 3D printed resin was produced by Asiga Max. Scanning the crowns sprayed by Shera scan spray using INEOS extraoral scanner to create STL files exported for comparison with master crown. We invest (90% to 10% Shera to distal water ratio) using Shera Fina 2000 investment material and cast with Sirona PFM dental cast alloy. Devasting and grinding out the excess alloy around the crown with a 3.3 bar pressure sandblasting. Repeating the scanning processes with casted crowns and compare the STL files in cloud-compare software. Using Auto Mesh to cut half the crown to make the result accurate. Comparing both before and after casting crown in STL files using cloud-compare software and get absolute mean and RMS value for each crown. The data points on each crown is already large enough, so we don’t use p value in our study. Results: CAD/CAM milled wax, PMMA and 3D printed burnout resin all found some of the abs mean and RMS value increase before and after casting compared to master crown. Milled wax has the least difference followed by 3D printing and PMMA. PMMA is the least accurate material in this experiment which would vary the amount of die spacer and cementation. Significance: High inaccuracies of PMMA material might affect the actual die spacing and cementation value, whereas milled wax performed the best. Milled wax and 3D printed resin are both within the clinical acceptable value.

Understandings of Syllogisms in Ontogeny and History: The Contributions of J. Piaget, A. R. Luria, M. Cole, and S. Scribner in Comparison
Authors: Oesterdiekhoff Georg W.
Published: March 2022

J. Piaget described how children first elaborate elementary, then empirical and finally logical deductions. A. R. Luria was one of the first to show that illiterate adults of premodern cultures exhibit no understanding of the syllogisms that presuppose logical deductions. He listed the explanatory factors that Piaget had also listed. An American research group led by M. Cole and S. Scribner repeated the syllogistic studies Luria had conducted. Although the results were replicated in different developmental regions and were consistent with Piaget and Luria's considerations, Cole and Scribner interpreted the results differently. They first confirmed the validity of the explanatory approach of Piaget and Luria. But then, in a second step, they withdrew this confirmation. According to their view, the test subjects did not want to deal with the logical problems because they considered other things to be more important. Finally, Cole and Scribner interpreted the answers in such a way that they might contain the same logical, abstract, and theoretical ability that is found in the answers that express an understanding of syllogisms. The present article reconstructs the argumentations of these three schools and criticizes the latter one.

Authors: Chi Lik Au Sunny
Published: March 2022

Objective: Blindness caused by mature cataract is reversible with timely cataract extraction surgery, however neglecting it could complicate with phacomorphic glaucoma. This study aims to investigate the psych socioeconomic determinants of phacomorphic glaucoma complicated and uncomplicated mature cataracts in Hong Kong. Participants and Methods: Retrospective review of cataract surgery records from 2013 - 2018 in a tertiary public emergency hospital’s ophthalmology unit in Hong Kong was done to identify phacomorphic glaucoma and uncomplicated mature cataract patients as case and control respectively. Data on demographics, psychiatric diseases, social and economic factors were extracted and analyzed. Results: 36 cases and 39 controls were included, with similar age (p = 0.73) and sex (p = 0.99). Presence of psychiatric diseases (p = 0.02) and absence of spouse (p = 0.008) were associated with phacomorphic glaucoma in univariate logistic regression analysis. Intention to private healthcare service usage (p = 0.002, p = 0.006) and living out of public rental housing (p = 0.002, p = 0.004) were associated with phacomorphic glaucoma in both the univariate and multivariate logistic regression analysis. Conclusion: Attention to screening of mature cataract before complication of phacomorphic glaucoma occurs should target the single elderly households, psychiatric patients, and the non-public housing population.
An Empirical Risk and Return Analysis of Select Stocks in NASDAQ 100
Authors: Banerjee Arindam
Published: March 2022

Stock market indices are considered to be a powerful economic indicator. These indices can be classified based on the methodology of weight allocation for each stock and the rules governing the entry, retention and exit criteria of various stocks in the index. This paper presents a descriptive and an exploratory analysis carried out on the daily returns data of NASDAQ 100 (^NDX) index and shortlist of 20 stocks in the index. Random sampling was conducted at the sector level strata of all stocks that make up the index. This approach was followed to avoid selection bias and that stocks from the varied sectors are represented equally for this analysis. R-squared values and correlation coefficients were used to determine the explain-ability and relationship between the stock returns and the index returns respectively. The paper applied descriptive univariate analysis on daily returns at an individual stock level and at an aggregated sector level. Inter-relationship between stocks and the index returns was carried out by computing Pearson’s correlation coefficient across the different combinations of stocks and index return values. Linear regression was carried out identify the explain ability of the variance in the returns of from the index to the returns from the stocks. All analysis was carried out using the python and the stats-models library. As anticipated, the returns of randomly picked 20 stocks were able to explain ~85 % of the variance of the returns of index. One of the primary focus of the paper was to explore whether NASDAQ-100 index can explain the variability of the technology stocks relatively more than the stocks that belong to other sectors in its portfolio owing to the nature of most stocks that make up the index.

Малый и средний бизнес (МСБ) вносят ключевой вклад в экономику страны с точки зрения трудоустройства, инноваций и роста. Развитие проектной деятельности может сыграть значительную роль в содействии этому вкладу, но МСБ требуют менее бюрократических форм управления проектами, чем те, которые используются более крупными традиционными орга-низациями. В этой статье проводится исследование для определения характера управления проек-тами требуемого МСБ, и результаты исследования представлены в данной статье.Полученные результаты очень убедительно свидетельствуют о том, что МСБ нуждаются в “облегченной” версии управления проектами.

Small and medium-sized businesses (SMEs) make a key contribution to the coun-try's economy in terms of employment, innovation and growth. The development of project activi-ties can play a significant role in facilitating this contribution, but SMEs require less bureaucratic forms of project management than those used by larger traditional organizations. This article pre-sents a study to determine the nature of project management required by SMEs, and its results. The research findings very strongly suggest that SMEs need a "lightweight" version of project manage-ment.
Метод машинного обучения для обратных задач теплопроводности
Authors: Keneskyzy K. , Yeskermes S.B.
Published: March 2022

Investigated in this work is the potential of carrying out inverse problems with linear and non-linear behavior using machine learning methods and the neural network method. With the advent of ma-chine learning algorithms it is now possible to model inverse problems faster and more accurately. In order to demonstrate the use of machine learning and neural networks in solving inverse problems, we propose a fusion between computational mechanics and machine learning. The forward problems are solved first to create a database. This database is then used to train the machine learning and neural network algorithms.The trained algorithm is then used to determine the boundary conditions of a problem from assumed meas-urements. The proposed method is tested for the linear/non-linear heat conduction problems in which the boundary conditions are determined by providing three, four, and five temperature measurements. This re-search demonstrates that the proposed fusion of computational mechanics and machine learning is an effec-tive way of tackling complex inverse problems.

В данной работе исследуется потенциал решения обратных задач с ли-нейным и нелинейным поведением с использованием методов машинного обучения и нейросетевого метода. С появлением алгоритмов машинного обучения стало возможным мо-делировать обратные задачи быстрее и точнее. Чтобы продемонстрировать, что машинное обучение и нейронная сеть могут быть использованы при решении обратных задач, мы пред-лагаем слияние вычислительной механики и машинного обучения. Передние задачи решают-ся в первую очередь для создания базы данных. Эта база данных используется для обучения алгоритмов машинного обучения и нейронных сетей. Обученный алгоритмиспользуется для определения граничных условий задачи по предполагаемым измерениям. Предложенный ме-тод апробирован для линейных/нелинейных задач теплопроводности, в которых граничные условия определяются путем проведения трех, четырех и пяти измерений температуры. Это исследование показывает, что предложенное слияние вычислительной механики имашинно-го обучения является эффективным способом.

Published: March 2022

Aims:

The purpose of this study was to determine whether there are differences in clinical and radiographic outcomes among three different stem designs for subtrochanteric osteotomy in Crowe type IV developmental dysplasia of the hip (DDH).

Methods:

A retrospective analysis of prospectively collected data was undertaken from a consecutive series of 37 Crowe type IV DDHs treatment of noncemented total hip arthroplasty with chevron subtrochanteric osteotomy in 30 patients. Patients are divided into three groups, including Ribbed group (using Link Ribbed stem; n = 14), Synergy group (using Synergy stem; n = 9), and Link Classic Uncemented (LCU) group (using LCU stem; n = 14), according to the design of the stem. The clinical and radiographic outcomes were evaluated.

Results:

All patients were followed for 36 months. The time of bone union of the LCU stem was significantly longer than that of the Synergy stem (P = 0.02) and the Ribbed stem (P > 0.05); the time of bone union of the Ribbed stem was longer than that of the Synergy stem (P > 0.05). The length of stem in the distal femur of the Ribbed stem (P = 0.000) and the Synergy stem (P = 0.001) is significantly longer than that of the LCU stem. There were three hips with malunion, stem loosening, and varus alignment, which were observed in the LCU stem. None of these were observed in Ribbed and Synergy stems. In total hip arthroplasty with a noncemented stem combined with subtrochanteric femoral osteotomy for Crowe IV DDH, 89.2% hips (33/37) can achieve good and excellent clinical outcomes. There were three hips (1 hip in the Ribbed stem and two in the LCU stem) with fair clinical outcomes and one hip (LCU stem) with poor clinical outcomes.

Conclusions:

Although Ribbed, Synergy, and LCU stems have similar clinical outcomes, the LCU stem has a tendency to a varus position, longer union time, malunion, and stem loosening, when compared with the Ribbed and Synergy stems. We recommend against adoption of the LCU stem for Crowe IV DDH with subtrochanteric femoral osteotomy.

Published: March 2022

The underlying endeavor of this paper is to understand the air pollution situation, particularly PM 2.5, in the major three cities of Bangladesh through the lenses of university students. In order to achieve this aim, a structured questionnaire was developed and scheduled interview was performed with the students from three universities of Bangladesh, namely Khulna University, Chittagong University, and Dhaka University. Data was collected on three categories: demographic, seasonal variation and consequences, and lastly some prevention perceptions. Accumulated data were analyzed by deploying descriptive statistics. Multinomial logistic regression, Pearson correlation along with PCA and cluster analysis were performed to understand the prevention perceptions. The result shows that air pollution has adverse effects on participants and air quality is most deteriorated during summer season. Statistically, pollution in Dhaka city is the most while least was found in Khulna city. Participants witness and bear the consequences of air pollution, but they think individual prevention measures are not at work. This study unveils the air quality problem in three major cities in Bangladesh and pollution problem is out of individual control. Further studies are encouraged to understand individual pollution control measures and policies.
IMPACT OF TRANSPORTATION NETWORK COMPANY (TNC) SERVICES ON OTHER MODES: THE CASE OF DHAKA, BANGLADESH
Authors: Ahmed Mostaq , Islam Muhaiminul
Published: March 2022

Widespread popularity of TNC services has significantly changed the realm of urban transportation. This study presents an empirical investigation of the impact of TNC services on the other conventional modes in megacity Dhaka, the capital of the developing country Bangladesh. For this study, multinomial logit models have been developed using data collected from household travel survey. The no TNC scenario information has been collected by asking the respondents about their preferred mode for a similar kind of trip in a no TNC scenario when a trip made by TNC has been found. This study has found that TNC services are drawing passengers mostly from the CNGs. The finding is actually similar to several other researchers who concluded that TNCs are actually competing with taxi services in the cities of the first world countries. Considering the nature of these CNG vehicles, they can be compared to the taxi services of the first world countries. This study has also found comparatively higher impact of TNCs on public transit than many other studies.

At the end of the 19th century, during the rise of the national liberation
movement of the Armenian people, the movement of the Young Turks – the
Turkish opposition forces, was launched against the sultanate regime. The
Young Turks sought to establish a constitutional, parliamentary order and put
the country on a European path of development. Realizing that their forces were
not sufficient to achieve this goal, the leaders of the movement tried to reach an
agreement and cooperate with the subject peoples of the Ottoman Empire,
including the political organizations of the Armenian people, who were fighting against the Sultanate tyranny. Numerous meetings and discussions of the
Hnchakyan party figures with the Young Turk leaders during the mentioned
period showed that the latter did not recognize the need for reforms in Western
Armenia, did not actually recognize the existence of the Armenian Question and
were led by the idea of assimilating the subject peoples of the Ottoman Empire
among the Turks and creating one Ottoman nation.

The American Civil War of 1861–1865 received a wide response in the
Armenian periodical press of the time, including the “Masyats Aghavni”
magazine.This periodical, which was representing the Armenian nationalconservative
current, was published in 1860–1865 in Theodosia edited by
Archimandrite Gabriel Aivazovsky.
“Masyats Aghavni” is one of the unique Armenian periodicals that predicted
the inevitability of the conflict between the northern and southern states before
the start of the US Civil War. The magazine attributes this to the election of
Abraham Lincoln, the representative of the Republican Party representing the
interests of the northern states, which is considered one of the remarkable
events of the time. According to the “Masyats Aghavni”, the main reason for
the outbreak of the civil war is the issue of slavery and slave trade, which the
North opposes, and the South does not want to give up the “profitable …
disgusting and ruthless habit” of exploiting the slave labor.

The biographical information on David Bek, the leader of the liberation movement of Syunik of the 18th century, is scant or non-existent. The combined analysis of the research conducted by different authors, separute evidence and manuscripts, enables us to conclude: 1. David Bek was presumably from Syunik, born in Tatev. In all likelihood, this was the reason he became the leader of the liberation movement of Syunik. 2. Genealogy records from the Urpeleants Certificate indicate that most probably David Bek’s father – Astvatsatur, actually descended from the Melik Parsadan lineage, was the son of Melik Bali I, the brother of Melik Parsadan II (Sargis Bek) and Ilya. This evidence was previously registered by Yervand Lalayan. 3. Contrary to popular belief that David Bek was not married and did not have a family, the documents contain reliable information that he was married and had heirs.

In traditional Armenian music-poetry, the manifestations of Gusan and
Ashugh art very often are not differentiated. The lack of clarity on this issue is a
consequence of disregarding the main characteristics of these expressions of
traditional art, along with the lack of research on Gusan art in general. The
absence of a clear distinction between the folk and folk-professional (secularprofessional)
branches of Armenian traditional musical-poetical art is also
important, due to its relation to the differentiation between Gusan and Ashugh
art, representing two areas of folk-professional branch. As for the study of the
specific features of Gusan and Ashugh art, there is less difficulty regarding the
latter, since today it is still in use. Whereas, when speaking of Gusans, we are
dealing only with some surviving musical-poetical examples, most often
exclusively the poetic texts, and ancient and medieval references, illustrative
material, and current research findings. A study of references about Gusan art
by ancient and medieval authors demonstrates its syncretic character. For the
differentiation between Ashugh and Gusan art, in particular, the defining
presence of theatrical elements is highly significant.

Al-Falah dalam Konsepsi Al-Qur’an

Published: March 2022

This article aims to know the concept of al-falah in the Qur'an. Al-Falah is defined as success. Success in the world is for example a form of wealth in business, the result of work to make a living that is financially profitable, while immaterial luck such as the purity of the soul, the spiritual side that will guide goodness. And the hereafter is the forgiveness of Your Lord, and His reward is good, and he is the All-mighty, the Allwise. Success (al-falāḥ) is only seen when the meaning of success (al-falāḥ) deals with those who obtain it (al-muflihūn), and when dealing with business or good deeds to obtain success (al-falāḥ). Similarly, success (al-falāḥ) is also seen when faced with those who fail to obtain success (al-falāḥ) as wrongdoers, and so on. Success (al-falāḥ) is necessary both for life in this world and in the hereafter
University-Public Partnerships for Disaster Recovery: Promoting Community Resilience Through Research, Teaching, and Engagement
Authors: Smith Gavin , Nguyen Mai
Published: March 2022

This article describes a state-supported, multiuniversity, interdisciplinary effort to address unmet disaster recovery needs identified by six hard-hit, low-capacity North Carolina communities following Hurricane Matthew. At the request of the director of the North Carolina Division of Emergency Management and the state governor, university officials created a team of faculty, practitioners, and students called the Hurricane Matthew Disaster Recovery and Resilience Initiative (HMDRRI). This 2-year program delivered research, teaching, and engagement activities of the sort that are not typically undertaken by federal or state emergency management agencies, insurance providers, or nonprofit organizations. HMDRRI also offered graduate students in land-use planning, landscape architecture, and architecture opportunities to help provide community assistance under the supervision and mentoring of faculty and practitioners. An overarching goal of the program was to help build greater rural resilience, an outcome that has received inadequate attention from academics and practitioners.
