Despite economic challenges, Colombo's commercial real estate market has shown resilience, with strong demand for high-end office spaces in the central business district driving a sustained growth. With limited Grade A office space and increasing demand for flexibility, co-working spaces have emerged as an attractive, cost-effective alternative for businesses seeking adaptable office solutions. These spaces promote collaboration, productivity, and employee satisfaction, driving the exploration of their impact on these factors to uncover insights that contribute to organizational success in this context. The study implemented a quantitative research methodology to gather data from employees working in co-working spaces across different sectors in Colombo city through a self-administered questionnaire, resulting in 100 complete responses. The survey measured essential variables, including employee productivity, satisfaction, and performance, using established scales. To investigate the effects between these variables, Partial Least Squares Structural Equation Modeling (PLS-SEM) was utilized with the aid of SmartPLS 4.1 software. The findings indicated that employee satisfaction serves as a positive mediator between employee productivity and performance, also revealing a significant positive effect on the other three direct effects examined. The Smart PLS SEM analysis confirmed that both employee satisfaction and productivity significantly influence employee performance in co-working spaces. This paper enhances knowledge on employee productivity and performance in co-working spaces, emphasizing the mediating role of employee satisfaction in Sri Lanka withing emerging economies. By investigating these factors, the study aims to provide valuable insights for key stakeholders including policymakers and business leaders on strategies to optimize coworking space designs, implement flexible Human Resources policies, foster collaboration, and enhance employee well-being, ultimately improving organizational success through employee engagement
Sustainable Bioethanol Production from Corn Husk using Saccharomyces cerevisiae: Optimization of Key Parameters for Enhanced Yield
Get PDFNon-renewable fossil fuels dominate energy use globally, prompting a shift to renewable biofuels and utilizing underused agricultural residues. This study aimed to evaluate effective agricultural waste materials for biofuel production and to optimize cultivation conditions to improve yield. Among the tested agricultural wastes (arecanut husk, arecanut leaf, rice husk and corn husk) fermented with Saccharomyces cerevisiae, corn husk produced significantly higher bioalcohol yields. Utilizing corn husk in fermentation media (4 g/L yeast extract, 8g/L KH2PO4, 0.6 g/L (NH4)2SO4, 0.3 g/L peptone, 0.6 g/L MgSO4.7H2O) with baker's yeast (25 g/L) at 30 ± 2 °C, 100 rpm for 24 hours yielded 0.3% ethanol. Sequential optimization increased yields significantly. Extending fermentation to three days raised ethanol production by 1.6 times (0.5%). Hydrolyzing corn husk with 1M H2SO4 improved bioalcohol yields compared to other agents. Optimizing media pH to 7.0 further enhanced production. Increasing corn husk substrate to 40g/100ml boosted ethanol content from 0.7% to 1.1%. Higher yeast inoculum (75 g/L) elevated bioalcohol yield to 1.2%, compared to non-optimized conditions (25 g/L). The findings reveal that corn husk can serve as a valuable raw material for bioalcohol synthesis, emphasizing the importance of process optimization to maximize yield.Keywords: Agricultural waste, Bioalcohol, Corn husk, Fermentation optimization, Lignocellulosic biomass, Saccharomyces cerevisiae
 
Mastering Strategic Thinking: A Comprehensive Review of Exploring Strategy: Text and Cases (13th Edition)
Get PDFThis review critically assesses the 13th edition of Exploring Strategy: Text and Cases by Whittington et al. (2024), a widely used textbook in management and business education. With its comprehensive scope and practical relevance, the book provides a strong foundation in strategic management for undergraduate, postgraduate, and MBA students, as well as practitioners. The book is organised into three main sections: strategic analysis, strategic choices, and strategy in action. Each section is supported by a few real-world case studies, theoretical frameworks, and discussions that foster student engagement and critical thinking. The authors effectively combine theory and practice by blending traditional tools such as SWOT and Porter's Five Forces with modern issues such as digital transformation and globalization. Key strengths include clarity, updated content, and a global perspective. However, some limitations are also present. The extensive content sometimes sacrifices depth, and certain chapters, such as those on strategic lenses, mergers and acquisitions, and post-strategy evaluation, lack detailed development or seamless integration. Additionally, while the international case studies are commendable, their strong European focus may limit their relevance for students outside of Europe. Compared to other strategy textbooks, such as those by Lynch et al.,(2024) or Wheelen et al.,(2025) ‘Exploring Strategy’ places more emphasis on critical thinking and multiple viewpoints instead of detailed theoretical steps and processes. Despite some minor issues, the book remains an important resource for developing strategic thinking skills, offering both conceptual insight and practical application in today’s complex business environment
The Influence of Subaltern Status on Celestinahami’s Fatalistic Suicide in Leonard Woolf’s “A Tale Told by Moonlight”
Get PDFThis position paper explores the suicide of Celestinahamy in Leonard Woolf’s "A Tale Told by Moonlight," contextualising it as a fatalistic suicide as defined by Emile Durkheim. Fatalistic suicide occurs due to extreme societal regulation and oppression, which Celestinahamy, a former sex worker in colonial Ceylon, experiences intensely. The analysis employs suicidological and postcolonial theories to explore how Celestinahamy's subaltern status, characterized by exotification, romanticization, selective representation, dehumanization, and stereotyping, drives her to suicide. Leonard Woolf's narrative, influenced by his colonial experience, portrays Celestinahamy's tragic life and ultimate despair. The paper also argues that her inability to resist the oppressive colonial structures and her misrepresentation as an exotic 'other' led to her fatalistic suicide, echoing Durkheim's theory and highlighting the dire consequences of subaltern suppression and marginalization
Women's participation in Ancient Sri Lankan politics: By literary and archaeological sources
No full textOrganizations aimed at building a society with equal opportunities have emerged in different countries of the world as well as in Sri Lanka, and a number of different programs are also being implemented. When focusing on Sri Lanka, it is important to investigation how ancient societies dealt with giving women an important status in society. The problem of this research is whether the woman had an important position like the man in the political affairs of ancient Sri Lanka ? The aims of this research are to briefly investigation the status of women in ancient Sri Lankan society, women's participation in political affairs, and whether women were given an important position in political affairs as well as men. The non-field method was used this research and according to the qualitative research method, the library research method was used to collect data by using primary and secondary sources, analyze the data and draw conclusions. Women's participation can be identified in many cases related to the political affairs of ancient Sri Lanka. Since the beginning of kingship and state development, women have held various powers like men and joined many political affairs. After kingship and state development, women have become indispensable in political affairs in various sectors. Women have also held important positions in politics and used various epithets. It can be clearly identified that women are even in the kingship, which is the highest stage of politics; they are above the king by giving advice to the king, leading the king, sometimes over men, acting as they want, etc. Because of this, it can be recognized that in the political affairs of ancient Sri Lanka, women were directly and indirectly involved in political affairs and were able to make a significant impact on political affairs, and for this, the position they held in society was very helpful

Emerging HRM Trends
No full textHuman Resource Management (HRM) is a universal consideration, and regardless of their type, almost all problems faced by organizations can, at least partially, be addressed through sound HRM. Emerging HRM trends refer to new developments or general patterns of change that are becoming increasingly visible in the field. Most of these trends are driven by broader business shifts such as globalization, technological advancement, demographic changes, and the growing emphasis on sustainability. In the 21st century, the role of HRM has evolved significantly from the traditional personnel function to a strategic role, then to a participative approach, and finally to a sustainability-oriented paradigm. Today’s HRM is vast, indispensable, business-driven, and sustainability-driven, constituting both a pure and an applied field of study and practice.
The objective of this research paper is to briefly identify and discuss key emerging HRM trends. While numerous trends merit attention, this paper will focus on eleven trends which are perceived as major ones: Hybrid and Flexible Working Arrangements, Greening in HRM, Employee Ethicality and Ethicality in HRM, Diversity, Equity, and Inclusion (DEI), Digital HRM, HRM Analytics, Employee Happiness and Holistic Well-being, Economic HRM and High-Performance Organization through HRM, Presenteeism, and Quiet Quitting.
Other notable trends not covered in this paper include work–life integration, knowledge management, HRM in mergers and acquisitions, managing call centre employees, robotics in HRM, and managing nomads. While these trends pose both challenges and opportunities for HRM professionals, they can be managed in ways that generate substantial benefits for all stakeholders. Challenges should be viewed as opportunities that can be efficiently and effectively capitalized on through appropriate thoughts and appropriate actions. In this era of unprecedented disruption and possibility, our role is to anticipate trends, embrace innovation, and humanize almost every transformation. The true measure of HRM’s success will not only be how well we manage processes, but how profoundly we elevate people, because only then it is possible for organizations to achieve sustainable excellence.

Designing High-Efficiency Tandem Solar Cells for Extraterrestrial and Terrestrial Applications: Performance Analysis Under Varying Spectral and Thermal Conditions
No full textEnergy independence and sustainability can be reached through tandem solar cells in extraterrestrial and terrestrial environments in the future. In this study, three advanced tandem solar cell models are configured numerically and assessed using SCAPS-1D (Solar Cell Capacitance Simulator) software, analyzed their key performance parameters under AM 0 (space sunlight) and AM1.5G (Earth sunlight) spectra by varying temperature range from extreme to normal while optimizing the main absorber layer thickness and interface properties. Selecting radiation-tolerant absorber layers such as ZnTe, CIGS, GaAs, and Perovskite are crucial. An organic-inorganic hybrid 2D-3D perovskite cell is selected for the top cell with CIGS/Si and CIGS/GaAs and as a bottom cell with ZnTe, considering the environmental adaptability. Among the built three tandem cell models, Perovskite (SnOx/PCBM/2D- MAPI/3D-MAPI/PEDOT)–CIGS/GaAs cell exhibited the best overall performance. Simulations carried out at 323K and 358K showed efficiencies of 31.8% and 29.8% under AM1.5G, and 29.3% and 27.4% under AM 0, respectively. These results highlight the superior efficiency and thermal resilience of the Perovskite CIGS/GaAs tandem architecture, highlighting its’ potential in contributing to designing resilient, stable high performance power generation solar cells for both terrestrial and space applications despite extreme conditions, making it a promising pathway for next-generation photovoltaics.
