Gender Inequality in Digital Transformation: Evidence from Business Process Management Industry in Sri Lanka

This research examines whether gender inequality exists in Leadership Style, Organizational Culture, and Digital Competence of digital transformation of the Business Process Management (BPM) industry. Data were collected from 507 employees of 40 Sri Lankan BPM companies through a web-based survey. Mann-Whitney U test with descriptive statistics provided evidence to strengthen the findings. The findings confirmed that gender inequality exists in Leadership Style, Organizational Culture, and Digital Competence of digital transformation in the BPM industry in Sri Lanka. This research contributes to "Acker's Theory of Gendered Organizations" by identifying areas that reproduce gender inequality in the new digital economy workplace. This study recommends controlling if not eradicating the gender inequality through proper Human Resource (HR) policies and procedures since it may hinder organizational performance. Digital workplace will improve employee retention, satisfaction, and productivity.

Vortices in vibrated granular rods

We report the experimental observation of novel vortex patterns in vertically vibrated granular rods. Above a critical packing fraction, moving ordered domains of nearly vertical rods spontaneously form and coexist with horizontal rods. The domains of vertical rods coarsen in time to form large vortices. We investigate the conditions under which the vortices occur by varying the number of rods, vibration amplitude and frequency. The size of the vortices increases with the number of rods. We characterize the growth of the ordered domains by measuring the area fraction of the ordered regions as a function of time. A {\em void filling} model is presented to describe the nucleation and growth of the vertical domains. We track the ends of the vertical rods and obtain the velocity fields of the vortices. The rotation speed of the rods is observed to depend on the vibration velocity of the container and on the packing. To investigate the impact of the direction of driving on the observed phenomena, we performed experiments with the container vibrated horizontally. Although vertical domains form, vortices are not observed. We therefore argue that the motion is generated due to the interaction of the inclination of the rods with the bottom of a vertically vibrated container. We also perform simple experiments with a single row of rods in an annulus. These experiments directly demonstrate that the rod motion is generated when the rods are inclined from the vertical, and is always in the direction of the inclination.Comment: 6 pages, 10 figure, 2 movies at http://physics.clarku.edu/vortex uses revtex

Awareness and utilization of HIV testing and prevention services among female sex workers in Dnipro, Ukraine: implications for prevention program strengthening from the dynamics study

INTRODUCTION: Approximately 240,000 people live with HIV in Ukraine, concentrated among key populations, including sex workers. Non-governmental organizations (NGOs) play an important role in the funding and delivery of HIV testing and prevention services in Ukraine. These services are set within the context of national healthcare reforms as well as ongoing armed conflict. This study seeks to describe and understand the usage of HIV testing and prevention services among sex workers in the eastern Ukrainian city of Dnipro. METHODS: A cross-sectional bio-behavioral survey was administered in September 2017-March 2018 among 560 sex workers working in Dnipro. Descriptive analyses of survey data are presented alongside multivariable logistic regression models identifying factors associated with NGO awareness and HIV testing in the past 12 months; adjusted odds ratios (AOR) and 95% confidence intervals (95% CI) are reported. RESULTS: Sixty-two percent of respondents were aware of NGOs offering HIV services. Sixty-eight percent had tested for HIV in the past 12 months, and 51% of those who reported the location of their most recent test were tested at an NGO. Those with 5-9 years in sex work had greater odds of being aware of NGOs (AOR = 5.5, 95%CI: 3.2-9.7) and testing for HIV (AOR = 3.4, 95%CI: 2.0-6.0) compared to those new to the profession. Contact with outreach workers was strongly associated with increased odds of testing (AOR = 13.0, 95%CI: 7.0-24.0). Sex workers in "offices" (brothel-like venues) reported higher odds of testing than all other workplaces, while those in entertainment venues (AOR = 0.3, 95%CI: 0.2-0.5) and public places (AOR = 0.2, 95%CI: 0.1-0.3) reported lower rates. Receiving prevention services, such as free condoms, was associated with increased testing (AOR = 16.9, 95%CI: 9.7-29.3). DISCUSSION: NGOs in Dnipro, Ukraine play an important role in HIV testing and prevention for women involved in sex work. However, focused efforts should be placed on supporting access to these services for women that are newer to sex work, and those working in entertainment venues or public places. Outreach workers appear to support access to HIV prevention information and supplies and facilitate linkages to HIV testing for sex workers

LEAF ADAPTABILITY OF lWO NON·TIMBER FOREST SPECIES Caryota urens L. AND Elettaria carrlamomum VAR. MAJOR PLANTED IN THE Pinus caribaea ENRICHMENT BUFFER ZONE IN SINHARAJA MAB RESERVE, SRI LANKA

Caryota urens L. and Elettaria cardamomum var. major are indigenous non-timberspecies which are used as market or sustainable goods and services for human orindustrial consumption. Both species thrive well in disturbed forest areas in the southwesternpart of Sri Lanka. Being understorey species, the growth of these species areaffected by sun light which is highly variable and often limiting resource in the forest.In a Pinus enrichment study established in 1991, leaf anatomical adaptability of these twospecies after 12 years of initial establishment under the Pinus buffer zone of the SinharajaMAB .reserve was investigated. Different light levels in the study area were created bythinning Pinus trees at different densities.Lower epidermis of C. urens showed highest (7.75 %) and lowest (6.35 %) stomatalindices in 2 pine rows removed treatment (2R) and 5 pine rows removed treatment (5R)respectively. Corresponding values for E. cardamomum were 6.00 % (highest) in theclosed canopy control (CU) and 5.22 % (lowest) in 1 pine row removed treatment (lR).The highest thickness of C. urens leaf cuticle (0.2611 ±0.02), leaf blade (22.2711 ±2.l4),upper epidermis (1.7511 ±0.10), lower epidermis (1.8311 ±0.06), palisade layer (6.2511±0.87) and spongy mesophylliayer (11.7411 ±1.30) were observed in 5R treatment thatreceived relatively high light levels than other treatments.E. cardamomum leaves showed highest thickness of leaf blade (22.4311 ±O.88), lowerepidermal layer (2.1211 ±O.ll), spongy mesophyll layer (10.3211 ±O.57) in 3 pine rowsremoved treatment (3R). The highest cuticle thickness (0.2311 ±O.OI) was recordered in 3pine rows under planting treatment (3U) while lR treatment showed highest upperepidermal layer thickness of 2.2111 ±0.15. Palisade layer was highest (4.74J! ±0.55) inCU.Results revealed that C. urens shows leaf adaptability to grow under relatively high sunlight levels (5R treatment) while E. cardamomum shows most of the leaf adaptabilitycharacters to grow under moderate light levels (3R treatment).The knowledge gained by this study is useful to recommend the optimum lightrequirements in terms of leaf anatomical traits of the study species.

Our past creates our present: a brief overview of racism and colonialism in Western paleontology

As practitioners of a historical science, paleontologists and geoscientists are well versed in the idea that the ability to understand and to anticipate the future relies upon our collective knowledge of the past. Despite this understanding, the fundamental role that the history of paleontology and the geosciences plays in shaping the structure and culture of our disciplines is seldom recognized and therefore not acted upon sufficiently. Here, we present a brief review of the history of paleontology and geology in Western countries, with a particular focus on North America since the 1800s. Western paleontology and geology are intertwined with systematic practices of exclusion, oppression, and erasure that arose from their direct participation in the extraction of geological and biological resources at the expense of Black, Indigenous, and People of Color (BIPOC). Our collective failure to acknowledge this history hinders our ability to address these issues meaningfully and systemically in present-day educational, academic, and professional settings. By discussing these issues and suggesting some ways forward, we intend to promote a deeper reflection upon our collective history and a broader conversation surrounding racism, colonialism, and exclusion within our scientific communities. Ultimately, it is necessary to listen to members of the communities most impacted by these issues to create actionable steps forward while holding ourselves accountable for the past

Patterns and Collective Behavior in Granular Media: Theoretical Concepts

Granular materials are ubiquitous in our daily lives. While they have been a subject of intensive engineering research for centuries, in the last decade granular matter attracted significant attention of physicists. Yet despite a major efforts by many groups, the theoretical description of granular systems remains largely a plethora of different, often contradicting concepts and approaches. Authors give an overview of various theoretical models emerged in the physics of granular matter, with the focus on the onset of collective behavior and pattern formation. Their aim is two-fold: to identify general principles common for granular systems and other complex non-equilibrium systems, and to elucidate important distinctions between collective behavior in granular and continuum pattern-forming systems.Comment: Submitted to Reviews of Modern Physics.

Sustainable development through proper land utilization Case study Ratnapura, Sri Lanka

Since the land is a scarce resource, the utilization of land effectively would be directly affected to thesustainable development of any country. A proper system ofland uti Iization is very essential especiallyfor a country like Sri Lanka which is very small in size and the majority of the people are dependingon the land related activities such as farming, grazing etc. as their major source of income. Unfortunately,land is in the state of under utilization in Sri Lanka. This paper attempts to study the importance of theeffective land utilization using Geographical Information Systems (GIS) for the sustainable development.The study was mainly based on the data gathered from Ratnapura Divisional Secretary area, Thearea is consisting with natural vegetations such as forests, shrubs. and man -rnade cultivation such astea, rubber, paddy. Also the area has a high economic value and it is well known for natural disasterssuch as floods and earth slips. Primary data was collected using semi-structured questionnaires,interviewing people and relevant officers and field surveying using hand held Global Positioning System(GPS). The study supplemented with secondary data such as remote sensing satellite images, existingmaps. GIS technique was used for the data analyses.The study identified 4 major issues in the specified areaI. 20 % of the total area is under utilization2. 25 % of the total area is misused3. 05 % of the total area is over utilized4. Continuous loss of land due to the natural disastersAccording to the results, the land has not used effectively in the area. 45% of the area is not usedeffectively. Since the country is very small, proper land utilization is very important. The study suggestthat an immediate action should be taken to overcome the matter. And also it is very important to getthe active participation of the general public to stop the loss ofland due to natural disasters and forfuture decision making.
