Impact of Green Supply Chain Management Practices on Organizational Performance of the Manufacturing Sector in Sri Lanka
The present study explores the impact of implementing Green Supply Chain Management Practices on Organizational performance, in terms of environmental, operational and financial performance among manufacturing firms in Sri Lanka. 150 no of firms (n = 150) which have already implemented GSCM practices in the Sri Lankan manufacturing industry were selected covering a variety of sectors including automobile (29), garments (36) , food and beverage (13), electronics (20), chemicals (20) and other (32) as the sample size of this study. Structural Equation Modeling (SEM) was used to analyze the relationship between variables. The empirical evidence verifies that, a significant positive relationship between GSCM practices and organizational performance exists. It can be concluded that higher the adaptation of GSCM practices, higher will be the organizational performance in Sri Lankan Context. Further, it is also concluded that higher the adaptation of GSCM practices, higher will be the environmental, operational and financial performance. This suggests, that the impact of GSCM practices lead to reduce air emission, wastage of water and solid wastages and decrease the consumption of hazardous materials, frequency of environmental accidents under the environmental performance. When considering operational performance, the impact of GSCM practices lead to increase amount of goods delivered on time, decrease inventory levels and scrap rate, promote products quality, reducing and eliminating waste, increased product line and finally improved capacity utilization. Decrease of cost for energy consumption, cost for environmental accidents, and decrease in level of production costs, decrease in packing costs can be considered under the financial performance. This study will play an important role for managers and firms, also this study is contributing in increasing the sales through understanding the benefits of practices of the green supply chain management and got the highest benefits from it.

The Use of Accounting in Supporting Sustainable Tourism The Case of the Sri Lankan Hotels
Around the world sun-and-sand tourism has become matured as a market compelling thetourism industry to focus on experiential tourism which encompasses sustainable tourism aswell. With the recovery of the global economic slowdown and end of North East conflict, thetourism sector in Sri Lanka is poised to mark a steady growth. The Sri Lankan hotels havetaken various sustainability strategies to attract tourists who are getting increasinglyconcerned of the impact of their activities on the environment/society. In this context,Environmental and Sustainability Management Accounting (EMA) emerges as a potentialaccounting tool that can support the sustainability strategies pursued by hotels. Due to thepaucity of research in this area, the study attempted to identify the drivers of EMA, theprocess of implementation and the challenges faced.The study followed a qualitative multiple case study approach in order to facilitate an indepth analysis. Primary data were collected by conducting eighteen semi structuredinterviews covering six publicly listed hotels. This was then supported by observations ofsome environment-related facility centres. Sustainability reports, annual reports, internalcompany records such as Green Book, daily and monthly material and energy records, etc.were content analysed as secondary sources of data. While collecting data, actions were takento improve the validity and reliability. The data gathered were analysed thematically.The study identified that favourable public image as the main driver of EMA practices of thehotels. Internal pressures such as group affiliation, top management compulsion and the needfor environmental management system accreditation also had an impact in shaping the EMApractices. When implementing these strategies the hotels seek the support of employees,guests and suppliers. It is further identified that engineers play a key role in implementing theenvironmental and EMA practices. Lack of proper guidance/awareness and fragmentedconventional management accounting principles were identified as the main challenges facedby the hotels for better application of EMA. This has resulted in a low level development interms of accounting. Thus, the Sri Lankan hotels can be benefited greatly if accounting canplay a vital role in implementing strategies aimed at promoting sustainable tourism
Digitalization and artificial knowledge for accountability in SCM: a systematic literature review
Purpose: In this study, the authors examine artificial knowledge as a fundamental stream of knowledge management for sustainable and resilient business models in supply chain management (SCM). The study aims to provide a comprehensive overview of artificial knowledge and digitalization as key enablers of the improvement of SCM accountability and sustainable performance towards the UN 2030 Agenda. Design/methodology/approach: Using the SCOPUS database and Google Scholar, the authors analyzed 135 English-language publications from 1990 to 2022 to chart the pattern of knowledge production and dissemination in the literature. The data were collected, reviewed and peer-reviewed before conducting bibliometric analysis and a systematic literature review to support future research agenda. Findings: The results highlight that artificial knowledge and digitalization are linked to the UN 2030 Agenda. The analysis further identifies the main issues in achieving sustainable and resilient SCM business models. Based on the results, the authors develop a conceptual framework for artificial knowledge and digitalization in SCM to increase accountability and sustainable performance, especially in times of sudden crises when business resilience is imperative. Research limitations/implications: The study results add to the extant literature by examining artificial knowledge and digitalization from the resilience theory perspective. The authors suggest that different strategic perspectives significantly promote resilience for SCM digitization and sustainable development. Notably, fostering diverse peer exchange relationships can help stimulate peer knowledge and act as a palliative mechanism that builds digital knowledge to strengthen and drive future possibilities. Practical implications: This research offers valuable guidance to supply chain practitioners, managers and policymakers in re-thinking, re-formulating and re-shaping organizational processes to meet the UN 2030 Agenda, mainly by introducing artificial knowledge in digital transformation training and education programs. In doing so, firms should focus not simply on digital transformation but also on cultural transformation to enhance SCM accountability and sustainable performance in resilient business models. Originality/value: This study is, to the authors' best knowledge, among the first to conceptualize artificial knowledge and digitalization issues in SCM. It further integrates resilience theory with institutional theory, legitimacy theory and stakeholder theory as the theoretical foundations of artificial knowledge in SCM, based on firms' responsibility to fulfill the sustainable development goals under the UN's 2030 Agenda
Utility of WIfI foot assessment tool in a Sri Lankan setting; an initial experience
Introduction: Potential for limb salvage and wound healing in a lower limb ulcer depends on degreeof ischemia, wound grade and superadded foot infection.Objectives: Our objective was to assess the feasibility of applying WIfI classification system to stratifypatients presenting with limb ulceration according to risk of undergoing amputation and benefit ofrevascularization.Methods: Fifty four consecutive patients with ulcerated limbs presenting over two months to theUniversity unit at the National Hospital were staged according to the Society for Vascular Surgery(SVS)Wound, Ischemia, and Foot Infection (WIfI) classification system.Results: The median age was 64 (39-93), and 42 (79%) patients were males. Diabetes (87%),hypertension (53%), ischemic heart disease (14%), cerebrovascular disease (13%), chronic renal disease(13%) were identified risk factors. Smoking was reported among 35%. Median Anterior TibialArtery(ATA), Posterior Tibial Artery(PTA), Toe pressures, Ankle Brachial Index, Pole test values ofthe affected side lower limbs were 114.5mmHg, 107.5mmHg, 41mmHg, 0.87 and 85cm respectively.Values for the contralateral limb were 140mmHg, 120mmHg, 74mmHg, 1.0 and 85cm respectively.84% of ATA and 90 % of PTA pulses were not palpable on the affected side. Grades of ischemia were;none (23.3%), mild (27.9%), moderate (18.6%), severe (30.2%), grades of infection were none (20.9%),mild (37.2%), moderate (39.5%), severe (2.3%), and wound grades were 0(0%), 1(20%.9), 2(39.5%),3(39.5%). Estimated risk of amputation were high (65.1%), moderate (11.6%), low (11.6%), very low(11.6%) and estimated benefit of revascularization were high (46.5%) moderate (23.3%), low (7.0%),very low (23.3%).Conclusions: Application of WIfI system was useful to prioritize patients with eminent limb loss forurgent intervention. Toe pressure assessment for diabetic foot ulcer stratification should become acommon practice
Expectations versus reality in chronic venous ulceration; a quality of life assessment study
Introduction: Chronic venous ulceration is a common problem worldwide with a significant effect onQuality of Life (QoL).Objectives: Our objective was to assess Sri Lankan patients’ perspective with regard to this scenario.Methods: We involved 141 consenting patients presenting to the OPD, National Hospital with a venousulcer lasting one month or more. Data was collected using an interviewer administered questionnaire, aclinical interview and a lower limb duplex scan. Short form 36 questionnaire was used for QoLassessment.Results: The majority were elderly (median age 53 years) men (n=9[69.5%]). Fifty four (38.3%) wereunemployed at the time of the study and 28 (19.9%) directly attributed the ulcer as the cause forunemployment. Median duration of ulcer was 10[1-360] months and mean Venous Clinical SeverityScore (VCSS) was 13.85(4-24). Family history (44[31.2%]), previous limb trauma or non-venoussurgery (24[17.0%]), smoking among men (57 [58.2%]) and history of pregnancy among females(34[79.1%]) were identified as risk factors. Role limitation due to physical health (28.4[SD 42.8]) androle emotional problems (40.9 [SD 46.7]) had a mean SF 36 score below 50. Factors such as pain,duration of ulcer, older age and higher BMI significantly affected many domains of QoL (p<0.05). Sixtysix (46.8%) patients continue to have ulcers despite having had surgical treatment for varicose veins.Conclusions: Venous ulcers have a considerable impact on the quality of life in Sri Lankan patientswith venous ulcer. The need for providing preventive and rapid healing methods together with socialsupport must be emphasized
Elliptic flow of electrons from heavy-flavor hadron decays in Au+Au collisions at 200, 62.4, and 39 GeV
We present measurements of elliptic flow () of electrons from the decays
of heavy-flavor hadrons () by the STAR experiment. For Au+Au collisions
at 200 GeV we report , for transverse momentum
() between 0.2 and 7 GeV/c using three methods: the event plane method
({EP}), two-particle correlations ({2}), and four-particle
correlations ({4}). For Au+Au collisions at = 62.4 and
39 GeV we report {2} for GeV/c. {2} and {4} are
non-zero at low and intermediate at 200 GeV, and {2} is consistent
with zero at low at other energies. The {2} at the two lower beam
energies is systematically lower than at 200 GeV for
GeV/c. This difference may suggest that charm quarks interact less
strongly with the surrounding nuclear matter at those two lower energies
compared to GeV.Comment: Version accepted by PR
Observation of charge asymmetry dependence of pion elliptic flow and the possible chiral magnetic wave in heavy-ion collisions
We present measurements of and elliptic flow, , at
midrapidity in Au+Au collisions at 200, 62.4, 39, 27,
19.6, 11.5 and 7.7 GeV, as a function of event-by-event charge asymmetry,
, based on data from the STAR experiment at RHIC. We find that
() elliptic flow linearly increases (decreases) with charge asymmetry
for most centrality bins at and higher.
At , the slope of the difference of
between and as a function of exhibits a
centrality dependence, which is qualitatively similar to calculations that
incorporate a chiral magnetic wave effect. Similar centrality dependence is
also observed at lower energies.Comment: 6 pages, 4 figure
Observation of Transverse Spin-Dependent Azimuthal Correlations of Charged Pion Pairs in at GeV
We report the observation of transverse polarization-dependent azimuthal
correlations in charged pion pair production with the STAR experiment in
collisions at RHIC. These correlations directly probe quark
transversity distributions. We measure signals in excess of five standard
deviations at high transverse momenta, at high pseudorapidities eta>0.5, and
for pair masses around the mass of the rho-meson. This is the first direct
transversity measurement in p+p collisions. Comparing the results to data from
lepton-nucleon scattering will test the universality of these spin-dependent
quantities.Comment: 11 pages, 5 figures, 15 tables. Submitted to PR
