Hinduisasi Di Kawasan Megalitik Gunung Slamet
Authors: Sulistyarto Priyatno Hadi
Published: April 2021

Kehidupan masyarakat megalitik menjalankan tradisi secara terus menerus hingga datangnya pengaruh kebudayaan Hindu-Buda. Hinduisasi di wilayah ini dilakukan dengan cara memanfaatkan sarana-sarana pemujaan megalitik, antara lain batu lumpang dan phallus. Konsep pemujaan yang digunakan pun masih sama yaitu kesuburan, suatu konsep yang mutlak diperlukan dalam masyarakat pertanian. Proses Hinduisasi tampak pada penggunaan lumpang batu dan phallus secara bersama-sama, yaitu dengan mendirikan phallus atau menhir ke dalam lubang lumpang sehingga menyerupai susunan lingga-yoni. Dengan demikian fungsi phallus atau menhir mewakili keberadaan lingga, sedangkan fungsi lumpang mewakili keberadaan yoni. Lingga dan yoni merupakan benda sebagai simbol dalam agama Hindu.

Can Free Community College Close Racial Disparities in Postsecondary Attainment? How Tulsa Achieves Affects Racially Minoritized Student Outcomes
Authors: Bell Elizabeth , Gándara Denisa
Published: April 2021

Promise programs, or place-based tuition-free college policies, have become increasingly popular among policymakers looking to expand postsecondary attainment. In this article, we examine Tulsa Achieves, a widespread, albeit understudied type of promise program that covers the balance of students’ tuition and fees after other aid is exhausted at a single community college. Utilizing a difference-in-differences and event-study design, we investigate the role Tulsa Achieves eligibility plays in promoting or hindering vertical transfer and bachelor's degree attainment across racial/ethnic groups. We find that Tulsa Achieves eligibility is associated with increases in bachelor's degree attainment within 5 years among Native American and Hispanic students and an increased likelihood of transfer within 4 years for Hispanic students.
The Hidden Side of Animal Cognition Research: Scientists’ Attitudes Toward Bias, Replicability and Scientific Practice
Authors: Farrar Benjamin George , Ostojic Ljerka , Clayton Nicola
Published: April 2021

Animal cognition research aims to understand animal minds by using a diverse range of methods across an equally diverse range of species. Throughout its history, the field has sought to mitigate various biases that occur when studying animal minds, from experimenter effects to anthropomorphism. Recently, there has also been a focus on how common scientific practices might affect the reliability and validity of published research. Usually, these issues are discussed in the literature by a small group of scholars with a specific interest in the topics. This study aimed to survey a wider range of animal cognition researchers to ask about their attitudes towards classic and contemporary issues facing the field. Two-hundred and ten active animal cognition researchers completed our survey, and provided answers on questions relating to bias, replicability, statistics, publication, and belief in animal cognition. Collectively, researchers were wary of bias in the research field as a whole, but less so in their own work. Despite sometimes (39.7% of responses) or often (38.8% of responses) hoping for one result over another, researchers reported that they could often (45.8% of responses) or always (38.4% of responses) detach from any biases to perform objectively fair tests of animal cognition. Over 70% of researchers endorsed Morgan’s canon as a useful principle but many caveated this in their free-text responses, and researchers self-reported that a median of 80% of their studies had been published. Their free-text responses suggested a stronger publication bias against negative and inconclusive results, and results that questioned “preferred” theories. Researchers rarely reported having performed questionable research practices themselves — however they thought that other researchers sometimes (52.7% of responses) or often (27.9% of responses) perform them. Researchers near unanimously agreed that replication studies are important but too infrequently performed in animal cognition research, and 44.7% of researchers agreed that their own area (44.7% of responses), or other areas (73.0% of responses) of research could experience a ‘replication crisis’ if replication studies were performed. Consistently, participants’ free-text responses provided a nuanced picture of the challenges animal cognition research faces, and highlighted many possible improvements. Overall, these data provide a picture of active researchers’ beliefs about the animal cognition research processes that can be used to inform debates on where and how the field can improve.
Meanings within meanings: Skilled readers activate irrelevant meanings of radicals in Chinese
Authors: Wang Tianlin , Borkenhagen M. Cooper , Barker Madison , Seidenberg Mark S.
Published: April 2021

Many characters in written Chinese incorporate components (radicals) that provide cues to meaning. These cues are often partial, and some are misleading because they are unrelated to the character’s meaning. Previous studies have shown that radicals influence the reader’s processing of the characters in which they occur (e.g., Feldman & Siok, 1999). We investigated whether readers automatically activate the semantic information associated with a radical even when it is irrelevant to the character’s meaning, using a modified version of the Van Orden (1987) task. Fifty-one Mandarin speakers participated in the study. On each trial they saw a reference category such as “animal” prior to seeing a character then indicated whether the target character was a member of that category. Decisions were slower and less accurate when a target that is not a member of the target category contained a radical that is. For example, if the category is “found in the kitchen,” the answer for the target 券 “ticket” is no; however the character contains the misleading radical 刀 “knife”. These patterns suggest that readers process the semantics of the radical even when it is not relevant to the meaning of the character. The results present challenges to the dominant theoretical understanding, which is that whole characters—not their individual components—are the units of processing in reading Chinese. They also raise questions as to whether repetitions of experience with the idiosyncrasies of the script may result in some of the irrelevant semantics influencing the meaning of the character.
Palaeomagnetic results from late Cretaceous and early Tertiary limestones from Tingri area, southern Tibet, China
Authors: Appel E. , Li H. , Patzelt A. , Wang J.
Published: April 2021

Palaeomagnetic studies have been carried out on the late Campanian (Zhepure Shanbei Formation: ZSbF), early Palaeocene (Zbepure Shanpo Formation: ZSpF) and early to mid-Eocene (Zhepure Shan Formation, memberV: ZSFmV) limestones from the Tethyan Himalaya west of Tingri (28°48'N, 86°54'E) in southern Tibet (China). A primary component in the ZSbF is proven by normal and reverse polarity zones in a stratigraphic succession of uniform layers (1 site, 24 specimens). The inclination (-50.2°) approximately fits to the expected palaeolatitude of the area for late Campanian. However, this result bas to be considered with caution because of non-antipodal remanence directions. The ZSpF shows a recent field direction only and is affected by gyroremanence acquisition. In contrast to results published earlier by Besse et al. (1984), no primary component could be identified in the ZSFmV. The characteristic remanence (ChRM) isolated in this unit (5 sites, 32 specimens) is most likely of secondary origin. The significance of the fold test is below the 95% level due to rather uniform bedding attitudes, but tilt corrected inclinations are unrealistically high for the area. The polarity of the ChRM is reverse and thus represents a palaeoremanence acquired sometimes between the Brunbes/Matuyama boundary and Eocene times. Declinations of Besse et al. (1984)'s primary direction and of our secondary component in the ZSFmV coincide and suggest that no rotation of the Tingri area occurred between Eocene and the time where the remanence was acquired.
Eco-friendly mining in the Himalaya: a case study of Kharidhunga magnesite deposit, Nepal
Authors: Mandal R.
Published: April 2021

Mining is one of the core sector industries which plays a positive and significant role in the process of country's economic development causing some unavoidable environmental impacts. Environment has become a key issue and today have transgressed the national boundaries and have now become a part of the global concern. We need eco-friendly mining for sustained development and better quality of life with minimum negative impact on environment without any threat to the future generation. In short, a balance has to be struck between development, environment and mining. Nepal has very short history of commercial mining and existing mines are small in size, located in hilly terrain and are being mined by opencast method. The mining activities may cause serious environmental degradation if proper techniques, management policies and practices are not utilised in time. This paper presents the holistic environment promotional effects which have been introduced at Kharidhunga magnesite mine.
Progressive development and risk analysis of rock avalanches: a case study in Higher Himalayan Crystallines of the Langtang National Park, central Nepal
Authors: Weidinger J. T.
Published: April 2021

Basic research work on the rare phenomenon of the Tsergo Ri mass movement in the Upper Langtang valley (Nepal Himalaya) during 1990-1996 has helped to identify the most important causes of this extraordinary event (Weidinger et al., 1996). Further investigations all along the valley revealed the preexisting structures in the crystalline rocks of the Higher Himalayan sequence that are also responsible for smaller but frequent landslides and/or rock avalanches (Weidinger, 1997).

Dynamic geomorphological changes are the result of weak rock behavior due to mechanical conditions of different lithology and seismotectonic structures. Rejuvenations of landslides and rockfalls are frequent as well. They often show a progressive development and/or continuous activity.

Keeping in mind the preexisting structures of the Tsergo Ri landslide, which have been described as brittle reacting leucogranite dykes, metamorphites with deformational fabrics, sulphide ore and neotectonic structures, four recently occurred rockavalanches (typical for the Langtang Valley) were investigated: one in the right side of the recent Langtang valley glacier (Langtang Tsang), about 2 km north of the Alp Pangri Goldum, one in the area of the broken crest of the Tsergo Ri mass movement, west of the glacier named Kyimoshung Tsang (both in the Upper Langtang Valley) and two more in the Lower Langtang valley, south of the "Landslide Lodge" and north of the "Lama Lodge".

Studying these phenomena from the geological and tectonical point of view, geomorphologic changes, morphodynamic development and triggering factors during a period of six years, made it possible to analyse future-risk for some parts of the area.

Ocena skutków regulacji zawartych w poselskim projekcie ustawy o zmianie ustawy – Kodeks pracy
Authors: Russel Piotr
Published: April 2021

According to the author, the proposed solutions should be considered in conjunction with other provisions which, within the current legal framework, in many areas favour people who conduct non-agricultural activities versus employees. Otherwise, they could be perceived as increasing an unequal treatment of these groups. In his opinion, the financial effects of the proposed regulations are difficult to estimate. Nevertheless, a slight increase in employers’ expenses may be expected due to the increased seniority bonuses and the need for accelerated payments of jubilee awards.

Permissible Medicine and Rationalization of Halal Pharma
Authors: Alzeer Jawad
Published: April 2021

Permissible medicine “Halalopathy” represents a compatible relation between therapeutic drug and human beliefs/lifestyles. Production of permissible drugs is achieved by evaluating ingredients and monitoring the production process to be compatible with a certain specific standard depending on the requirement of the lifestyle or belief of the patient. If drugs and beliefs are compatible, a domino chain effect will be initiated; trust will be developed, and the placebo effect will be activated. Consequently, a compatible system between mind and drug is established, faith in the treatment is intensified, entropy is lowered, potential energy is increased, and self-assurance is enriched. The compatibility concept is based on finding a connection between human’s belief and therapeutic drug where certain genes will be turned off epigenetically. Halalopathic medicine represents a new therapeutic concept in which holistic values - material, human, moral and spiritual values - are used to deliver the right treatment to the right patient.
Using of licensed and unlicensed anti-obesity medications among the university students
Authors: Elsahory Nour
Published: April 2021

Background: Obesity is one of the most serious problems worldwide. Using anti-obesity medications have gained growing interest among adults as a shortcut for bodyweight management practice. This study aimed to determine the prevalence, knowledge, usage determinants, intake pattern and experienced effects of anti-obesity medications, licensed and unlicensed, among university students in Jordan. Materials and Methods: A cross-sectional study was conducted using a structured web-based questionnaire. Univariate and multivariate logistic regression analyses were used. Results: 418 students with a mean age of 21.5 responded to the questionnaire. The prevalence of anti-obesity medication intake was 11%. The majority (67.2%) had scored poor knowledge regarding these medications. The intake patterns indicated that 78.3% of the consumers were self-administrated without prescription and 76.1% of the consumers used licensed type. Despite being perceived as useful in weight reduction, vomiting, and nausea, were very common adverse events (65.2%). Besides being obese, students with excellent knowledge demonstrated higher odds (OR=24.38 (95%CI: 8.12-73.19) and 10.48 (95%CI: 4.03-27.26), respectively) for medication consumption compared with other, p < 0.0005. Conclusion: Using anti-obesity medications among university students is of concern, particularly due to using unlicensed types and the lack of clinical prescription. With the reported poor knowledge, it becomes crucial to launching awareness campaigns and tailored programs for this age group and the general population.
Posterior spinal fixation using penetrating endplate screws in patients with diffuse idiopathic skeletal hyperostosis–related thoracolumbar fractures
Authors: Hishiya Takahisa , Ishikawa Tetsuhiro , Ota Mitsutoshi
Published: April 2021

OBJECTIVE

Diffuse idiopathic skeletal hyperostosis (DISH)–related vertebral fractures essentially require operative treatment due to severe fracture site instability and high potential risk of posttraumatic neurological deficit. However, the optimal surgical procedure remains unclear. The purpose of this study was to assess the efficacy of posterior spinal fixation with penetrating endplate screws (PESs) for DISH-related thoracolumbar fractures.

METHODS

The authors conducted a retrospective, single-center, observational study. They included data from 26 consecutive patients with DISH-related thoracolumbar fractures who were treated with posterior spinal fixation using either conventional pedicle screws (PS group, n = 8) or a combined PES technique (PES group, n = 18) between 2013 and 2019. Age, sex, BMI, bone mineral density, fracture level, use of antithrombotic drug, blood loss, operation time, fixation range, perioperative American Spinal Injury Association Impairment Scale score, implant failure, revision surgery, complications, and mortality were compared. The authors also evaluated screw loosening and bone healing on radiographs and CT scans.

RESULTS

More patients had vertebral fractures in the lumbar spine in the PS group than in the PES group (3 vs 0; p = 0.019). Patients in the PES group had less blood loss (63 vs 173 ml; p = 0.048) and shorter range of fixation (5 vs 5.5 levels; p = 0.041). The screw loosening rate was significantly lower in the PES group than in the PS group (3% vs 49%; p < 0.001).

CONCLUSIONS

Posterior spinal fixation using a PES technique may be an ideal surgical procedure for thoracolumbar fractures with DISH, providing more rigid and less invasive fixation than PS.

Published: April 2021

OBJECTIVE

Degenerative cervical myelopathy (DCM) is among the most common pathologies affecting the spinal cord but its natural history is poorly characterized. The purpose of this study was to investigate functional outcomes in patients with DCM who were managed nonoperatively as well as the utility of quantitative clinical measures and MRI to detect deterioration.

METHODS

Patients with newly diagnosed DCM or recurrent myelopathic symptoms after previous surgery who were initially managed nonoperatively were included. Retrospective chart reviews were performed to analyze clinical outcomes and anatomical MRI scans for worsening compression or increased signal change. Quantitative neurological assessments were collected prospectively, including modified Japanese Orthopaedic Association (mJOA) score; Quick-DASH; graded redefined assessment of strength, sensation, and prehension–myelopathy version (GRASSP–M: motor, sensory, and dexterity); grip dynamometer; Berg balance scale score; gait stability ratio; and gait variability index. A deterioration of 10% was considered significant (e.g., a 2-point decrease in mJOA score).

RESULTS

A total of 117 patients were included (95 newly diagnosed, 22 recurrent myelopathy), including 74 mild, 28 moderate, and 15 severe cases. Over a mean follow-up of 2.5 years, 57% (95% CI 46%–67%) of newly diagnosed patients and 73% (95% CI 50%–88%) of patients with recurrent DCM deteriorated neurologically. Deterioration was best detected with grip strength (60%), GRASSP dexterity (60%), and gait stability ratio (50%), whereas the mJOA score had low sensitivity (33%) in 50 patients. A composite score had a sensitivity of 81% and a specificity of 82%. The sensitivity of anatomical MRI was 28% (83 patients).

CONCLUSIONS

DCM appears to have a poor natural history; however, prospective studies are needed for validation. Serial assessments should include mJOA score, grip strength, dexterity, balance, and gait analysis. The absence of worsening on anatomical MRI or in mJOA scores is not sufficient to determine clinical stability.
IMPLEMENTASI KEBIJAKAN PENYIANGAN KOLEKSI DI UPT PERPUSTAKAAN UNIVERSITAS MUHAMMADIYAH MATARAM

Published: April 2021

Hasil penelitian menunjukkan bahwa UPT Perpustakaan Universitas Muhammadiyah Mataram sampai saat ini belum memiliki kebijakan secara tertulis dalam melakukan proses penyiangan koleksi perpustakaan. Proses penyiangan di perpustakaan Universitas Muhammadiyah Mataram akan diadakan setiap tiga tahun sekali bersamaan dengan proses Stock Opname. Perpustakaan UMMAT tidak memiliki tim khusus untuk melakukan penyiangan,  yang berwenang melakukan penyiangan koleksi adalah pihak perpustakaan dan dibantu oleh mahasiswa prodi D3 perpustakaan, dikarenakan kurangnya tenaga pengelola perpustakaan. Kendala yang dialami oleh perpustakaan Universitas Muhammadiyah Mataram dalam melakukan penyiangan diantaranya adalah, waktu untuk melakukan penyiangan maupun stok opname harus bersamaan dengan hari libur mahasiswa, masih banyak buku-buku yang sudah tidak layak pakai tetapi masih dibutuhkan oleh pemustaka sehingga proses penyiangan ini terhambat karena harus memilih buku apa yang harus di siangi, kurangnya tenaga pengelola perpustakaan sehingga tidak ada yang menangani khusus proses penyiangan koleksi perpustakaan, dan kegiatan ini tidak ada dalam aturan tertulis sehingga tidak ada anggaran khusus.

Published: April 2021

Background: The most advanced disease-modifying therapies (DMTs) in development for Huntington’s disease (HD) require intrathecal (IT) administration, which may create or exacerbate bottlenecks in resource capacity. Objective: To understand the readiness of healthcare systems for intrathecally administered HD DMTs in terms of resource capacity dynamics and implications for patients’ access to treatment. Methods: Forty HD centres across 12 countries were included. Qualitative and quantitative data on current capacity in HD centres and anticipated capacity needs following availability of a DMT were gathered via interviews with healthcare professionals (HCPs). Data modelling was used to estimate the current capacity gap in HD centres. Results: From interviews with 218 HCPs, 25% of HD centres are estimated to have the three components required for IT administration (proceduralists, nurses and facilities). On average, 114 patients per centre per year are anticipated to receive intrathecally administered DMTs in the future. At current capacity, six of the sampled centres are estimated to be able to deliver DMTs to all the anticipated patients based on current resources. The estimated waiting time for IT administration at current capacity will average 60 months (5 years) by the second year after DMT availability. Conclusion: Additional resources are needed in HD centres for future DMTs to be accessible to all anticipated patients. Timely collaboration by the HD community will be needed to address capacity gaps. Healthcare policymakers and payers will need to address costs and navigate challenges arising from country- or region-specific healthcare delivery schemes.
User-centric framework to facilitate trust worthy cloud service provider selection based on fuzzy inference system
Authors: Sujatha M. , Geetha K. , Balakrishnan P.
Published: April 2021

The widespread adoption of cloud computing by several companies across diverse verticals of different sizes has led to an exponential growth of Cloud Service Providers (CSP). Multiple CSPs offer homogeneous services with a vast array of options and different pricing policies, making the suitable service selection process complex. Our proposed model simplifies the IaaS selection process that can be used by all users including clients from the non-IT background. In the first phase, requirements are gathered using a simple questionnaire and are mapped with the compute services among different alternatives.In the second phase, we have implemented the Sugeno Fuzzy inference system to rank the service providers based on the QoS attributes to ascertain the appropriate selection. In the third phase, we have applied the cost model to identify the optimal CSP. This framework is validated by applying it for a gaming application use case and it has outperformed the online tools thus making it an exemplary model.
An intelligent system to identify coal maceral groups using markov-fuzzy clustering approach
Authors: Alpana  , Chand Satish , Mohapatra Subrajeet , Mishra Vivek
Published: April 2021

Coal is the mixture of organic matters, called as macerals, and inorganic matters. Macerals are categorized into three major groups, i.e., vitrinite, inertinite, and liptinite. The maceral group identification serves an important role in coking and non-coking coal processes that are used mainly in steel and iron industries. Hence, it becomes important to efficiently characterize these maceral groups. Currently, industries use the optical polarized microscope to distinguish the maceral groups. However, the microscopical analysis is a manual method which is time-consuming and provides subjective outcome due to human interference. Therefore, an automated approach that can identify the maceral groups accurately in less processing time is strongly needed in industries. Computer-based image analysis methods are revolutionizing the industries because of its accuracy and efficacy. In this study, an intelligent maceral group identification system is proposed using markov-fuzzy clustering approach. This approach is an integration of fuzzy sets and the markov random field, which is employed towards maceral group identification in a clustering framework. The proposed model shows better results when compared with the standard cluster-based segmentation techniques. The results from the suggested model have also been validated against the outcome of manual methods, and the feasibility is tested using performance metrics.
StimulEye: An intelligent tool for feature extraction and event detection from raw eye gaze data
Authors: Krishnamoorthy Amrutha , Sindhura Vijayasimha Reddy , Gowtham Devarakonda , Jyotsna C. , Amudha J.
Published: April 2021

Extraction of eye gaze events is highly dependent on automated powerful software that charges exorbitant prices. The proposed open-source intelligent tool StimulEye helps to detect and classify eye gaze events and analyse various metrics related to these events. The algorithms for eye event detection in use today heavily depend on hand-crafted signal features and thresholding, which are computed from the stream of raw gaze data. These algorithms leave most of their parametric decisions on the end user which might result in ambiguity and inaccuracy. StimulEye uses deep learning techniques to automate eye gaze event detection which neither requires manual decision making nor parametric definitions. StimulEye provides an end to end solution which takes raw streams of data from an eye tracker in text form, analyses these to classify the inputs into the events, namely saccades, fixations, and blinks. It provides the user with insights such as scanpath, fixation duration, radii, etc.
Some improved pythagorean fuzzy Dombi power aggregation operators with application in multiple-attribute decision making
Authors: Liu Peide , Khan Qaisar , Mahmood Tahir , Khan Rashid Ali , Khan Hidayat Ullah
Published: April 2021

Pythagorean fuzzy set (PyFS) is an extension of various fuzzy concepts, such as fuzzy set (FS), intuitionistic FS, and it is enhanced mathematical gizmo to pact with uncertain and vague information. In this article, some drawbacks in the Dombi operational rules for Pythagorean fuzzy numbers (PyFNs) are examined and some improved Dombi operational laws for PyFNs are developed. We also find out that the value aggregated using the existing Dombi aggregation operators (DAOs) is not a PyFN. Furthermore, we developed two new aggregations, improved existing aggregation operators (AOs) for aggregating Pythagorean fuzzy information (PyFI) and are applied to multiple-attribute decision making (MADM). To acquire full advantage of power average (PA) operators proposed by Yager, the Pythagorean fuzzy Dombi power average (PyFDPA) operator, the Pythagorean fuzzy Dombi weighted power average (PyFDWPA) operator, Pythagorean fuzzy Dombi power geometric (PyFDPG) operator, Pythagorean fuzzy Dombi weighted geometric (PyFDPWG) operator, improved the existing AOs and their desirable properties are discussed. The foremost qualities of these developed Dombi power aggregation operators is that they purge the cause of discomfited data and are more supple due to general parameter. Additionally, based on these Dombi power AOs, a novel MADM approach is instituted. Finally, a numerical example is given to show the realism and efficacy of the proposed approach and judgment with the existing approaches is also specified.

The demand for a providing QoS adaptive routing over IoT networks is always a challenge among current research community. This research work KHAI proposes a framework for QoS-adaptive routing approach, which incorporates Krill Herd optimization model over IoT network. Variable QoS user preference and handling differential service types over a scalable IoT network shows that challenge for designing an adaptive QoS is a must. Research survey suggest that major works have been carried out on bandwidth appreciable services and route management approaches. Hence QoS adaptive user defined services, which adapt to variable service priority levels based on user demand and network resource utilization is proposed in this research work. The performance analysis of proposed approach shows an improved throughput of 97.51 Mbps and minimal packet loss of 37.29% over a session in comparison to traditional computational approaches. Considering large scale of interconnected IoT devices, proposed approach delivers near optimal solution of throughput and adaptive utilization of network resources.
The neurologist and the hydrops
Authors: Redon Sylvain , Elzière Maya , Donnet Anne
Published: April 2021

The presence of endolymphatic hydrops has been studied in many neurological disorders. The pathophysiological mechanisms may involve CSF pressure variations, transmitted to the innear ear. This hydrops could play a role in vestibular or cochlear symptoms. For the ENT specialist, the etiological diagnosis of endolymphatic hydrops is a challenge, and neurological etiologies must be known. The treatment of these neurological causes could be effective on cochleo-vestibular symptoms. The knowledge of endolymphatic hydrops could also be a target for noninvasive tests, able to estimate CSF pressure variations. For the neurologist, this could represent a useful tool for the diagnosis and follow-up, in some of these neurological disorders, related to a CSF pressure imbalance. The purpose of this paper is to summarize literature data on endolymphatic hydrops in neurological disorders. We define some neurological conditions, for which there is a particular interest in noninvasive investigations of endolymphatic hydrops.

BACKGROUND: Office workers spend significant time in sedentary behaviors. Exploration of interventions to address this concern is warranted. OBJECTIVE: This study explored the impact of individualized goals and ergonomic modifications on sedentary behaviors and perceived health and well-being among office workers. METHODS: A six-week, one-group, pre- and post-test design was utilized to assess sedentary behaviors and perceptions of health and well-being among office workers using the RAND 36-Item Short Form Survey (SF-36), Numerical Pain Rating Scale (NPRS), Pittsburgh Sleep Quality Index (PSQI), Sedentary Behavior Questionnaire (SBQ), actigraphy, and a workstation assessment. RESULTS: Statistically significant improvements were noted from pre- to post-test on the RAND SF-36 for energy/fatigue (p = 0.000) and emotional well-being (p = 0.049) and subjective sleep quality using the PSQI (p = 0.005). Participants (n = 17) could set up to two goals related to health and well-being. A majority of the 31 established goals were met: increase physical activity (n = 11/16), reduce sedentary behavior (n = 8/11), and improve personal health (n = 3/4). CONCLUSIONS: The use of individualized goals and ergonomic modifications is effective for addressing perceived health and well-being among office workers. However, limited statistical significance was found regarding the impact of these interventions on sedentary behaviors or activity levels.
Uses of content analysis in economic sciences: An overview of the current situation and prospects
Authors: Oleinik A. N.
Published: April 2021

The article discusses the status of quantitative and qualitative data in economic sciences, as well as methods for transforming data into information and knowledge. Particular attention is devoted to content analysis as a set of methods for aggregating, processing and analyzing qualitative data; its forms (qualitative, quantitative and mixed methods) and uses by economists. Content analysis appears to be particularly suitable for non-orthodox economists because of their refusal to consider price as the only source of economic information. The content analysis of metadata of articles indexed in Web of Science and eLibrary suggests that Russian economists still have insufficient familiarity with the principles of content analysis and their applications to research compared with their Western counterparts. It is argued that the creation of on-line platforms for content analysis and on-line banks of qualitative data may become a trigger for changing this situation.
Percepción local de los factores claves de la resiliencia en destinos turísticos
Authors: Gutiérrez Vega Cecilia
Published: April 2021

La presente investigación, tiene como objetivo medir factores de resiliencia en destinos turísticos afectados por desastres naturales, enfocándose en la percepción que tienen los diferentes actores locales de los territorios. Para este caso de estudio se consideraron dos destinos afectados por el terremoto y tsunami del 27 de febrero de 2010, que corresponden a los municipios y destinos litorales de Licantén y Pichilemu, en la zona central de Chile. Como metodología se aplicó un modelo análisis comparativo Shift –Share que permitió medir y comparar los factores de resiliencia de destinos y su percepción por parte de: Gobierno Local, Empresarios y Residentes. Los factores medidos corresponden a Capacidades, Propiedades y Conexiones. Como principales resultados, la resiliencia difiere bastante entre un destino y otro, destacando que son las conexiones y capacidades las mejor percibidas y finalmente las propiedades de resiliencia. Respecto al factor más favorable, las conexiones, estas se perciben aceptables en los dos destinos, estando en orden de prioridad Licantén y luego Pichilemu. Por otro lado, al realizar el análisis comparativo entre destinos, se manifiesta claramente que la resiliencia en Pichilemu es mayor que en Licantén, lo que generó una recuperación más rápida del destino.

Dada la escasez de recursos las universidades públicas han puesto un especial interés en la consecución de sus objetivos de forma eficiente, lo anterior cobra una mayor relevancia ya que la Universidad es un organismo con metas no financieras, pero requiere de recursos públicos para poder operar. El objetivo de este estudio es estimar la productividad de las universidades públicas mexicanas durante el periodo 2007 a 2017, para ello, se utilizó la técnica no paramétrica del Análisis Envolvente de Datos para estimar los Índices de Productividad de Malmquist a un total de 44 universidades públicas. Los hallazgos principales indican que hay una evolución positiva en la productividad, la cual en promedio representa el 5,2% y que esta tiene principalmente una relación más significativa con la mejora de los procedimientos de investigación, y no necesariamente con el uso eficiente de los recursos de que disponen las unidades analizadas. Las conclusiones centrales son, que a partir de los Índices de Productividad de Malmquist se puede saber cuáles factores son los que contribuyen principalmente en la productividad, sin embargo, los esquemas de financiamiento para el contexto universitario mexicano podrían influir en la actuación de los gestores y en el resultado de estas.

Published: April 2021

In this study, the effects of recycled tire rubbers (RTR) and steel fiber (SF) on the fresh and hardened state properties of the self-compacted alkali activated concrete (SCAAC) were investigated. The ground granulated blast furnace slag, 1 % hooked-end SF, and two types of RTR were utilized. The crumb rubbers (CR) and tire rubber chips (TCR) were used as a substation to natural aggregates at substation levels of 10 % and 15 %. The fresh state performances were evaluated by T50 value, slump flow, V-funnel, and L-Box tests, while mechanical performances were assessed through compressive, flexural, and splitting tensile strength tests. Also, detailed crack and microstructural analyses were conducted. The RTR adversely affected the fresh state properties, which reduced more with SF inclusions. Among the RTR, the TR specimens exhibited lower fresh state performance than the CR specimens. Similar mechanical strengths were obtained on the TR and CR specimens under the same replacement ratios. However, TR specimens exhibited higher deformation capacities than the CR specimens, when SF was utilized. The SCAAC specimens with 1 % SF and 15 % RTR showed more and wider flexural cracks, higher mechanical strength, and deformation capacity, which can be utilized in structural applications, particularly in high seismic zones.
