Published: June 2021

Clinicians have noted an increase in the level of hepatic transaminase in patients with the new coronavirus infection COVID-19 a number of times, and an unambiguous answer to the question of what caused this change in laboratory indices has not been received yet. The course of COVID-19 is often complicated by the development of haemophagocytic syndrome, and preventive anti-inflammatory therapy is required for its treatment, which is represented by biologic drugs (interleukin-6 inhibitors or JAK-kinase blockers) and glucocorticosteroids. It has been noted that the level of ALT and AST increases against the background of biological therapy.

The objective of the present studywas to analyze the possible effect of biological therapy on the functional state of the liver.

Material and methods. The study randomly included 38 patients diagnosed with ICD-10 U07.1 (18 women and 20 men). Inclusion criteria were control of aspartate aminotransferase (AST), alanine aminotransferase (ALT), bilirubin at least three times during the period of hospitalization, as well as an increase in these indicators above the reference values. This study was carried out while prescribing preventive anti-inflammatory therapy.

Results. The median (Me ± SD) age of the patients was 57 ± 14.67. Mann–Whitney U-test showed no significant difference in the activity of liver enzymes and total bilirubin upon admission to the infectious diseases hospital (p> 0.05). A statistically significant difference in indicators evaluation at admission and at discharge was determined using the Wilcoxon test for ALT levels in the group receiving biologic drugs (p = 0.004). In other cases, there was no statistically significant difference (p > 0.05). When analyzing the level of enzymes for the entire period of hospitalization with the use of Friedman criterion, the level of changes in hepatic transaminases in the group with the use of biologic drugs turned out to be equal for ALT p = 0.001. When assessing changes over the entire period of hospitalization by the de Ritis coefficient, the p-value was also significant (0.001) in this group.

Conclusion. This study shows the necessity to control the level of hepatic transaminase, especially when prescribing biological therapy for haemophagocytic syndrome.

One of the development efforts in the health sector is the availability of quality health services. The clinic is a health institution that reaches out to the community directly to provide treatment to the community. In order to create excellent service, the clinic must pay attention to the services provided to patients. Patient satisfaction is very important to be considered by the clinic management. Patient satisfaction is one indicator of the success of providing health services to the community. Mitra Sandona clinic is one of the clinics located in the city of Padang. This clinic provides BPJS services to patients. Health service satisfaction is achieved if what the patient gets exceeds his expectations. To determine patient satisfaction, an analysis tool called importance performance analysis is needed. This matrix analyzes the level of expectations and experiences felt by patients. Through this matrix, the clinical management can determine which level of importance should be improved, enhanced and maintained
Comparative Efficacy of Two Types of Antibiotic Mixtures in Gut Flora Depletion in Female C57BL/6 Mice
Authors: Goulding David R , Myers Page H , Dickerson Angela B , Comins Molly M , Wiltshire Rebecca A , Blankenship-Paris Terry L
Published: June 2021

Over the last decade, interest in the role of the microbiome in health and disease has increased. The use of germ-free animals and depletion of the microbial flora using antimicrobials are 2 methods commonly used to study the microbiome in laboratory mice. Germ-free mice are born, raised,
and studied in isolators in the absence of any known microbes; however, the equipment, supplies, and training required for the use of these mice can be costly and time-consuming. The use of antibiotics to decrease the microbial flora does not require special equipment, can be used for any
mouse strain, and is relatively inexpensive; however, mice treated in this manner still retain microbes and they do not live in a germ-free environment. One commonly used antibiotic cocktail regimen uses ampicillin, neomycin, metronidazole, and vancomycin in the drinking water for 2 to 4 wk.
We found that the palatability of this mixture is low, resulting in weight loss and leading to removal of mice from the study. The addition of sucralose to the medicated water and making wet food (mash) with the medicated water improved intake; however, the low palatability still resulted
in a high number of mice requiring removal. The current study evaluated a new combination of antibiotics designed to reduce the gut microbiota while maintaining body weights. C57BL/6NCrl mice were placed on one of the following drinking water regimens: ampicillin/neomycin/metronidazole/vancomycin
water (n = 16), enrofloxacin/ampicillin water ( n = 12), or standard reverse osmosis deionized water (RODI) ( n = 11). During an 8 day regimen, mice were weighed and water consumption was measured. Feces were collected before and after 8 d of treatment. Quantitative real-time
PCR (real-time qPCR) for 16S bacterial ribosome was performed on each sample, and values were compared among groups. The combination of enrofloxacin and ampicillin improved water intake, together with a greater reduction in gut flora.
Kant on the Necessity of Necessity
Authors: Leech Jessica
Published: June 2021

One of Kant’s categories—a priori concepts the possession and applicability of which are necessary conditions of possible experience—is a concept of necessity. But it is unclear why the concept of necessity, as Kant defines it, should be a category thus understood. My aim is to offer a reading of Kant that fills this lacuna: the category of necessity is required to make necessity as it features in the world of experience understandable: a concept that the understanding can grasp and employ in cognition of objects. Kant’s view has potential wider significance for accounts of the function of necessity judgments.

Authors: Yañez Agustina , Spagarino Carlos Raúl , Villalba Cayetano , Paiva Eber
Published: June 2021

Introducción y objetivos: Acrostichum danaeifolium es una especie ampliamente distribuida en el Neotrópico, que crece en hábitats de agua dulce o salada. En Argentina y Paraguay son escasos los registros citados por artículos previos. El objetivo del presente trabajo es estudiar a A. danaeifolium para Argentina y Paraguay haciendo énfasis en la revisión de su distribución y la historia de las colecciones botánicas de la especie.
M&M: Se estudiaron especímenes depositados en herbarios nacionales e internacionales y coleccionados durante tareas de monitoreo en el Parque Nacional Río Pilcomayo (Formosa, Argentina), y se consultaron registros en las bases de datos GBIF e iNaturalist. El análisis de los caracteres diagnósticos fue realizado bajo lupa estereoscópica.
Resultados y conclusiones: Se ilustran los caracteres diagnósticos de A. danaeifolium y se provee un mapa de la distribución en Argentina y Paraguay. Se corrobora que las poblaciones de A. danaeifolium registradas hasta el momento para ambos países son escasas y se restringen al distrito del Chaco oriental, donde crecen asociadas a terrenos inundables como márgenes de ríos y lagunas de agua dulce. Los especímenes hallados en el Parque Nacional Río Pilcomayo      representan el primer registro de la especie en un área protegida y para la provincia de Formosa, el registro más boreal para Argentina y la primer colección de la especie para el país en 70 años. Debido a la intensa deforestación que atravesó el distrito del Chaco oriental en las últimas décadas, el PNRP cobra especial relevancia para la conservación de la especie.
The Comparison of Chunking Methods to Enhance the Cognitive Capacity of Short-term Memory to Retain Textual Information among High School Students
Authors: Suppawittaya Piwat , Yasri Pratchayapong
Published: June 2021

Our short-term memory has a limited capacity of taking in information and retaining it the memory storage. However, this can be enhanced by various memory techniques especially dividing the information into smaller chunks. To investigate this memory enhancement strategy, this study compared the effectiveness of three chunking methods, namely One-Chunk, Two-Chunk, and Three-Chunk to enhance the capacity to retain information in the forms of letters and numbers in the short-term storage. Participants in this study were 50 high school students who took part in an experimental design of online short-term memory assessment. The results revealed that the ability to remember 10 distinct alphabets and 10 distinct digits statistically varied, depending on how the information was chunked. To be more precise, the student participants could memorize the information when divided into 2 or 3 chunks more effectively than one full set of the information (1 chunk) as the mean scores gained in the two chunking methods were statistically greater than that of the One-Chunk delivered information. However, the findings only relied on single types of information so that further research could be done to explore this with more complicated information. Educational implications can be drawn from this present study that in order to assist students to memorize and retain learning materials more effectively, it is essential to help classify them into 2-3 groups of information. This could be done through the use of tree thinking, binary thinking, and computational thinking.

Published: June 2021

Antioxidants and herbs have been scientifically proven to be one of the substances that can prevent cervical cancer. The incidence of cervical cancer in Indonesia is very high and is a vital cause of death of women in Indonesia. Every day 40-45 new cases emerge, which means 20-25 people die from cervical cancer in Indonesia. Several previous studies have shown that there are plants, fruits and seeds that contain high antioxidants and are believed to prevent and reduce pain due to cervical cancer. Besides, many herbs that also found in Indonesia are known to affect cancer cells. Ficus auriculata can find in Indonesia. However, not many people use the available natural resources that are suspected to prevent cervical cancer. This study was a preliminary study analyzed of Aristolone in Ara Fruit used as a prediction of apoptosis in HeLa cells. The results showed that the positive effect of Aristolone content in F. auriculata affected proliferation supported by previous studies.

The ethical-political dimension of social and community praxis: The case of Ecuador´s early response to covid-19
Authors: Capella Manuel
Published: June 2021

In Ecuador, the painful impact of the covid-19 pandemic elicited early responses by the government, and by local communities. This critical, positioned and exploratory case study analyses such responses, underscoring the fundamental ethical-political dimension of any academic and professional praxis aimed at the construction of healthier societies worldwide. While critical traditions are familiar with this stance, the inequalities and ideological mechanisms made visible by covid-19 responses may enable the wider community of researchers and practitioners to join ongoing collective ethical-political efforts. Findings from Ecuador underline the potentially harmful role of neoliberalism, and issues of democratic legitimacy; significant problems before and during the pandemic shock; and official discourses which blame communities for their own suffering and death. Neutrality and depoliticized notions of scientific evidence are notoriously insufficient in these scenarios. We need to engage more deeply with diverse forms of global and local community resistance, in times of covid-19, and beyond.

The effect of attitudes towards individuals with sexual convictions on professional and student risk judgments
Authors: Harper Craig A. , Hicks Rachel
Published: June 2021

Attitudes towards individuals with sexual convictions is an area with growing research interest, but the effects of such attitudes on professional judgments is largely unexplored. What is known from the existing literature is that attitudes guide the interpretation of sexual crime related information, which cascade into potential biased or heuristically driven judgments. In this study we recruited samples of both students (n = 341) and forensic professionals (n = 186) to explore whether attitudes towards individuals with sexual convictions predicted risk judgments of hypothetical sexual offense scenarios, and whether this relationship is moderated by professional status or perpetrator characteristics. Forensic professionals expressed more positive attitudes overall, but the significant effect of attitudes on risk judgments was consistent between participant groups and was not moderated by perpetrator age or sex. We suggest that relying on attitudes as a basis for risk judgments opens the door to incorrect (and potentially dangerous) decision-making and discuss our data in terms of their potential clinical implications.
Individual Accountability in International Economy Policymaking after the Global Financial Crisis
Authors: Pagliari Stefano , Kovras Iosif
Published: June 2021

In the aftermath of the global financial crisis, the design of accountability mechanisms has taken on renewed importance in academic and policy debates. Calls for holding individuals whose actions and omissions contributed to the meltdown accountable have gained traction in a number of countries after the crisis. Yet, individual accountability norms are seemingly absent from the international economic agenda in response to crisis. In this paper we address this puzzle by exploring the evolution of two major international organisations, the IMF and the FSB, in bringing accountability following financial crises. Our analysis reveals how these institutions have increasingly incorporated in their toolkit policy recommendations related to the unethical or illegal conduct by government officials of individuals in the financial industry, but these tools were geared almost exclusively towards forward-looking policies designed to deter the reoccurrence of illegal or unethical behavior rather than punishing or scrutinizing past wrongdoing. We argue that the extent to which individual accountability norms permeate the international economic agenda is mediated by the institutional characteristics of the organizations that comprise the international financial regime.

Interpersonal Trust on Jihadi Internet Forums
Authors: Hegghammer Thomas
Published: June 2021

This chapter explores the effects of the trust problem on jihadi internet discussion forums. The scarcity of non-verbal cues in digital communication facilitates deceptive mimicry, which undermines the interpersonal trust required for sensitive transactions. Open-source data from Arabic-language jihadi forums between 2006 and 2011 indicate that distrust there was high and direct recruitment rare. General trust also declined over time as policing of the forums increased. As of 2014, forums are still in use, but primarily for low-stake activities such as propaganda-sharing and ideological debate, not recruiting or operational coordination. Confidence in the authenticity of propaganda remained relatively high, due to vetting institutions and hard-to-fake video formats. A modicum of interpersonal trust also remained, thanks to reputation systems and a few relatively reliable signs of trustworthiness involving time expenditure. The trust problem is an Achilles heel for high-risk activists online, including pro-democracy activists in authoritarian settings.

Published: June 2021

A review of literary sources on the diameter distribution of trees and marketability structure of black alder stands in the Slobozhanskyi forest typological district and the whole of Ukraine is carried out, the relevance of this study is established. Comparison of forest typological and forest management zoning is presented for a clearer identification of the study region, as a prerequisite for the creation of regional standards for forestry. The analysis of the distribution of black alder in the forest fund of the study region is carried out and the forestry and evaluation indicators of the alder forest stands are studied. The distribution of black alder stands of the region by origin, forest types, density of stocking and productivity has been evaluated. The evaluation indicators and marketability structure of black alder stands in the study region are considered. Models of the diameter variability of the modal stand, the ratio of the variability of the industrial timber part to the total dimensional variability of the stand, taking into account the minimum and maximum diameters in the modal stand, have been calculated. The relationship between the proportion of industrial timber and the age of modal alder stands of coppice origin has been established. The tables of the marketability structure dynamics of modal alder stands were created, taking into account the distribution of the volumes of industrial timber by dimensional classes, consistent with European approaches to round timber measurement. When compiling the standards, the previously developed yield tables of modal black alder stands of coppice origin of the Slobozhanskyi forest typological district, a comparative analysis of the dynamics of the output of industrial timber in modal black alder stands according to different standards is carried out. When comparing the standards developed for the Slobozhanskyi forest typological district with the standards developed for the whole of Ukraine, it was found that in the latter the output of industrial timber is significantly higher, which is primarily associated with the forest site conditions of the region and the coppice origin of forest stands.

Published: June 2021

Development of renewable energy production is one of the main directions of decarbonizing the Ukraine’s energy sector as well as the forestry sector. Increase in woody biomass utilization efficiency at producing energy, alongside with securing the proper level of technological processes and technical equipment, also requires a reliable information support toolbox that would facilitate managerial decisions. An important constituent of this toolbox is represented by the regional assessments of energy function of forest plant communities. The information basis of the research is formed by the information from the industrial database of IA “Ukrderzhlisproekt”, which contains the detailed biometric characteristics of the stands in the studied region, as well as by a system of mathematical models for quantitative assessment of foersts’ live biomass and dead organic matter. As a result, the quantitative values of the total energy content in live biomass and daed organic matter of Zhytomyr Polissia’s forests were determined. The total amount of energy accumulated in vegetal biomass of the region's forests is 3035.7 PJ, which corresponds to 100.2 million tons of conventional fuel. At the same time, the share of the total energy content in dead organic matter is 11.1 %. The structure of energy content in vegetal biomass in the region is dominated by pine stands, which accumulate more than 60 % of the energy of forests of Zhytomyr region, including 70.8 % - in live biomass of tree trunks. More than 40 % of energy is accumulated in vegetal biomass of stands of I site index class, which mainly grow in fairly infertile forest growth conditions. In the general structure of energy content in dead organic matter (336.2 PJ) more than 60 % belongs to forest litter (212.8 PJ which is not considered a source of renewable energy), standing dead trees 12.3 % (41.3 PJ), dry branches – 17.8 % (close to 60 PJ). The results obtained in the course of the research will serve as an information background for the formation of a strategy for development of forest bioenergy in Zhytomyr region.

Amber mining has already led to an environmental catastrophe on a regional scale. According to official data, more than a thousand hectares of land, mostly located in the Central Polissya region (Zhytomyr region), have suffered very severe damage and need to be restored. The conservation value of such areas is lost, and further use for forestry or agriculture is very risky. To develop norms of anthropogenic loads on landscapes, it is mandatory to study anthropogenic transformation by identifying their current ecological status, establishing the dependence of changes on the intensity of anthropogenic loads individually for each natural region. The source materials for obtaining the results are the materials of field research, taxonomic descriptions of plantations, satellite and aerial photographs, as well as the establishment of temporary test areas according to the generally accepted methodology in forestry. The problem that arose in the Zhytomyr region as a result of unauthorized amber mining contributes to the rapid growth of anthropogenic pressure on forestry landscapes, causes them irreparable damage, leads to environmental and economic crisis, imbalances in the social situation of the population, environmental problems, there are significant changes in the structure and mineral composition of the soil layer of forest lands, completely or partially destroyed the living above-ground cover and undergrowth, undergrowth undergoes significant changes in habitat conditions and anthropogenic pressure. Violation of the ecological balance of the forest at different stages of biological development can lead to irreversible consequences in the forestry sector. The obtained results are promising for further development of own methods of ecological and economic assessment of the damage caused by the consequences of illegal amber mining.
Nomenclature of woody plants in the State Register of Plant Varieties of Ukraine
Authors: Mezhenskyj V. M. , Mezhenska L. O.
Published: June 2021

The efficiency of plant resources depends on the correct use of plant names. Ukrainian names of plants belonging to the botanical and agrobiological classification are widely used in the scientific agricultural literature, but both of them are not definitively organized. The crop names have long been used in agricultural practice, in particular during the systematization of regionalized plant varieties. During the registration of a variety, the taxon to which it belongs is indicated and the taxon is indicated by this name in the State Register of Plant Varieties suitable for dissemination in Ukraine. The names of plants adopted in the State Register are a mixture of correct and incorrect names, which arose as a result of an unconscious adaptation of the names of agrobiological nomenclature by likening them to the names of botanical taxa. The list of registered varieties belonging to certain taxa, which are grouped by economic use there is in the State Register. Sometimes varieties and taxa are placed in inappropriate groups. Varieties belonging to the same taxon are sometimes denoted by different species names. Obsolete Latin names or their spelling has a deviation from the accepted given for some taxa of woody plants. Some of the botanical taxa are named by crop names. Russified crop names instead of specifically Ukrainian ones occur and the rules of normative transliteration of varietal names are violated. The plant names constructed in the State Register have negative impact on professional literature. They destroy the system of agrobiological nomenclature and contradict the norms of the scientific style of the literary Ukrainian language. The recommendations of the International Code of Nomenclature for algae, fungi, and plants should be followed and the «Rules of Plant Nomenclature, Taxonomy, and Cultonomy», designed to regulate Ukrainian plant names to correct these shortcomings, should be applied.

The study of phytocenotic diversity in the light of modern scientific concepts of its preservation is now a new and to some extent holistic worldview of this global problem for humanity. According to the panphytocenocentric concept, its solution should be carried out at the local, regional, national and international levels. Protection of phytocenotic diversity in Ukraine has become an integral part of the concept of ecologically balanced development, national programs for biodiversity conservation as a mandatory element of state environmental policy. Therefore, it is important to preserve phytocoenotic diversity as a set of phytocoenotic taxa, which reflect all levels of organization of phytocoenosystems, which were formed in the process of phylocenogenesis in various eco-conditions and assessed by a set of geososological features. The purpose of the publication is a comprehensive level analysis of the current composition of the rare phytocenosis of Ukraine, establishing a new list of rare syntaxons, elaboration of the latest structure of the second official edition of the Green Book of Ukraine and outlining tasks for the future. The issues of the second official edition of the “Green Book of Ukraine” are considered. In this context, a critical analysis of the syntaxonomic composition of the currently functioning rare phytocenofund of Ukraine is carried out, methodological violations of their selection are revealed, the structure of the description of rare syntaxons is offered. The authors have identified 983 associations of 104 formations, which will be taken as the basis for the second official publication of the “Green Book of Ukraine”. An important element of the syntaxonomic protection of vegetation is also the creation of regional (oblast) lists of rare associations based on the principles of creating the “Green Book of Ukraine”. For the first time a modern rare phytocenofund for its main natural regions has been determined: Ukrainian Polissya, Ukrainian Carpathians, Podolsk part of the forest zone, Forest-steppe of Ukraine, Steppe of Ukraine, Mountain Crimea.

Published: June 2021

Objective: Breast Cancer is the leading cause of mortality and morbidity amongst Indian females. Breast self-examination (BSE) as an early detection modularity can have a profound effect on lowering mortality, if it is practiced regularly. The aim of this study was to assess the knowledge, attitude, and practice of Breast Self-examination amongst Indian women, aged 30 years and above. Methods: A validated questionnaire, consisting 35 questions measuring ‘Knowledge, Attitudes and Practice of Breast Self-Examination’ was widely circulated amongst 1000 females throughout India and responses were collected for a duration of 3 weeks, from 2nd, September 2020 to 23rd,September 2020. Results: Despite having knowledge about the technique of performing BSE, the respondents did not have a positive attitude towards it and were reluctant to practice BSE. A total of 54.4%, 15.1%, 21.3% and 9.2% of respondents were from the Northern, Southern, Western and Eastern regions of India, respectively. The overall median (IQR) KAP score was 70.0 (16.0) out of a maximum of 110. The knowledge, attitude and practice domain scores were 22.0 (5.0), 36.0 (7.0), and 13.0 (8.0) out of a maximum of 30, 52 and, 28, respectively. All three individual score domains were significantly correlated with each other and the total score.Conclusion: Despite having knowledge about the technique of performing BSE, the respondents did not have a positive attitude towards it and were reluctant to practice BSE.

Objective: Polyarteritis nodosa (PAN) is a rare disease with complex clinical manifestations that are difficult to diagnose. Imaging diagnoses of previously reported patients have focused on vascular manifestations. Magnetic resonance imaging (MRI) has been used to detect muscle involvement in PAN. Here, we reviewed imaging findings pertaining to muscle involvement in patients with PAN. Methods: Twelve articles concerning muscle involvement in PAN were published during the period 1980–2020; 21 patients, including our patient, were examined in this study. Results: Across the published articles, the male to female ratio was 1:1, the mean patient age was 40.76 ± 18.28 years, and there were 17 patients with calf involvement and 3 with thigh involvement. The T1WI and T2WI findings were both isointense in one patient, and the T1WI findings alone were isointense in seven patients. The T1WI findings were slightly hyperintense in five patients, and no T1WI images were available for the remaining seven patients. The T2WI signal was diffusely hyperintense in 10 patients, and “patchy villous hyperintense” in 9 patients. Among the 12 patients with enhanced images, most exhibited diffuse or cotton-like enhancement, while some showed involvement of the fascia and periosteum. The comprehensive imaging analysis of our patient included muscle and blood vessel MRI and computed tomography (CT) examinations. Our patient’s disease involved the calves and thighs, with T1WI isointensity and T2WI patch-like hyperintensity, as well as cotton-like enhancement centered on blood vessels. Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) examinations of the lower limbs showed beadlike changes in the arterial branches, and the lower leg arterial branches were obvious. Head MRA revealed stenosis and occlusion of the right middle cerebral artery. Additionally, the superior mesenteric artery was locally dilated around a tumor, with the greatest width being approximately 9 mm. Cerebral perfusion analysis indicated cerebral blood flow (CBF) was lower in the right cerebellar hemisphere.Conclusions: PAN should be considered in the presence of patchiness or diffuse muscle signal changes on MRI of the lower leg (or thigh), followed by vessel-centered cotton-like enhancement accompanied by fascial or periosteal enhancement. Our findings suggest that systemic examination of small and medium arteries in patients with PAN can aid early prevention and treatment.

Published: June 2021

Ovarian involvement in multiple myeloma is extremely rare. This paper reports a case of a 50-year-old female who presented with lower back and chest pain of one-month duration. Computed tomography imaging showed lytic lesions in the sternum, ribs, thoracic and lumbar vertebrae with a right adnexal mass. On pathological examination, plasmacytoma was confirmed from the adnexal mass. Bone marrow examination revealed plasma cell infiltration in bone marrow with positive light chain IgG lambda type in serum and raised microglobulin. She was finally diagnosed as a case of IgG lambda myeloma with ovarian plasmacytomas (RISS II).

Published: June 2021

The aim of the study is to determine the factors that fluctuate the numbers of IPOs (NIPOs) issued in Pakistan from 1992 to 2017. Firstly, the study examined the impact of macroeconomic factors such as GDP, Consumer Price Index (CPI), market return, Industrial production index, market volatility, and political stability on the NIPOs. Secondly, the study determined the impact of political regimes (i.e. democratic regime and military regime) on the NIPOs. The censored Tobit regression model is used to determine the relationship between dependent and independent variables. The study found that economic growth positively influences the NIPOs over time in Pakistan; however, market returns, inflation negatively affected the NIPOs. The study further found the number of IPOs shows an overwhelming increase in the military regime, contrary to the democratic regime.

This study is an attempt to investigate the impact of information and communication technologies (ICTs) development on the participation of women in economic activities in Pakistan. Data for the period 1991-2017 was used for this research work and regressed on female economic involvement and ICTs development and another set of control variables like GDP, FDI and trade liberalization. Data sources are the WDI, IFS, and ESP. Johansen cointegration test, VECM and Granger causality tests were used to estimate data. Estimation techniques were applied after checking the properties of time series data. Results indicate the positive and significant relationship of dependent variable female economic participation and independent variables ICTs development and macro-economic variables in the long run. The study findings indicate that female economic participation has increased with the increase in ICTs in Pakistan. However, the rate of women's economic participation was not found as increasing as in other developed countries, and it is not as rapid as technology developed in the last decade.
