A Systemic Model for Managing and Evaluating Conflicts in Organizational Change

Change or innovation diffusion is a key issue for most business organizations but is yet difficult to implement as the change management process is often complex as it relies on an organized methodology to complement an organization\u27s commitment and participation. An ambiguous environment surrounding change mechanism tends to develop unintended attitudes, resulting in resistance and conflict. The study proposes a model for the management of such conflicts among change participants (involved and affected) in the context of organizational change. The authors consider organizational change process as an innovation project that treats change and conflicts holistically with the Ulrich\u27s notion of boundary considerations (boundary critique). A social network setting of multiple stakeholders is considered to effectively help in resolving problematic situations that hinder organizational learning and change. The proposed model provides a theoretical foundation based on concepts governing Critical Systems Heuristics (CSH), change theory, stakeholder theory and conflict managemen

Systemic Problems in Information Technology Adoption and Use: A Systems Thinking Perspective

Understanding and creating the conditions under which information systems will be embraced by human organizations (thinking systems) remain a high-priority research issue. Despite numerous benefits associated with Information Technology (IT), there exist some intervening factors (systemic problems or issues) that impede technology’s widespread adoption and use in organisations. Established information technology adoption models like TAM, TRA etc. view technology adoption from the users’ perspective without taking a strategic perspective into account. As an alternative focus we suggest that addressing systemic problems can be a method of reducing fundamental barriers to organizational progress. This paper presents some real life examples of IT projects in organizations which experienced failures or barriers related to IT adoption processes. The issues are framed as systemic problems and are analysed from a ‘systems thinking’ perspective. The paper argues that some of the issues contributing to the failure/barrier cannot be easily explained by traditional user acceptance models like TAM or TAM2. The paper presents a number of systems thinking principles that can be used to analyse organizational contexts. It also provides some recommendations and suggests a new research direction based on the marriage of ‘Systems Thinking’ approaches and ‘Adoption Model Theories’. This research will help in identifying the relationships between the determinant factors of the technology acceptance models and the concepts involved in systems thinking approaches. We believe the integration of the two approaches will facilitate improved technology adoption, organizational learning and change

Sanctuary in the Midst of Crisis? A Look into Shariah Indices using Multivariate GARCH DCC

Islamic Finance has evolved over the past few decades, and stands at over a trilliondollars today. At the foundations of Islamic finance lay the concept of risk sharing, and the purest forms of it in the modern day finance is equity investments. The evidence of Islamic investors pursing equity investments in reality is thin. Multitude of reasons are attributed to this low participation, mainly revolving around lack of empirical proof of Islamic investments being a reliable and steady return alternative. This study is an attempt to study the volatilities and correlations with the conventional global equity indices utilizing Multivariate GARCH Dynamic Conditional Correlations (MGARCH DCC) method. The findings provide an interesting angleto our study, where there is a significant downwards trend in the correlations during the crisis era. This provides substance to the argument that Islamic investors would experience lesser downside in economic crisis. This study further dwells into the linkage of Islamic indices with global financial indices to study if financial sector exclusion from Islamic indices benefits theinvestors. The findings are positive, with lower correlations and that to reducing in the recent global crisis. Islamic finances core philosophy is equity based investments and this study is a humble attempt to empirically substantiate its benefits

An Investigation on Academic Writing Problems Encountered by Undergraduate Students of Shaheed Benazir Bhutto University, Sanghar Campus

The aim of this research is to investigate the academic writing problems encountered by undergraduate students of Shaheed Benazir Bhutto University, Sanghar Campus and to suggest the effective strategies to cope up these problems. Qualitative method was used to collect the data in which 12 students and 3 teachers were selected for semi structured interviews. The conducted interviews were thematically analyzed. Findings of this research revealed that the lack of logical thinking, intended delivering expressions and repetition of ideas in academic writing are the major problems of student. Teachers recommended some strategies that writing short sentences, using simple vocabulary, mind mapping, influential language and cohesive devices can help students to improve academic writing.  The study suggested that critical reading and frequent feedback from teachers will help students to overcome the problems of academic writing. Keywords: Academic writing, logical thinking, undergraduate students, and vocabulary. DOI: 10.7176/JLLL/68-03 Publication date:May 31st 202

Bonded amalgam as a fissure sealant in low-income setting: A randomised controlled trial

Objectives: To compare one year retention rate of bonded amalgam sealants (BAS) with that of conventional resin-based sealant (RBS). Methods: It was a parallel group, equivalence, randomised controlled trial done during March 2018 to December 2019 at the dental clinics of Dow University of Health Sciences, and the Jinnah Sind Medical University, Karachi, Pakistan on children aged 12-16 years, who were randomly assigned to one of the two treatment groups (BAS vs. RBS). Complete retention of the sealant at one year follow-up was labeled as success. Multi-level mixed effect logistic regression model was employed. Study was registered at www.clinicaltrials.gov # NCT NCT03130725. Results: There were 137 teeth (23 subjects) in the BAS and 128 teeth (15 subjects) in the RBS group that were evaluated for sealant retention at 12 months follow-up. Among the BAS group, 100/137 (73%) sealants were completely retained whereas 110/128 (86%) were fully retained in the RBS group. Nearly, 22/137 (16%) BAS and 10/128 (7.8%) RBS were completely dislodged. In multivariable analysis, subject age \u3e15 years and male gender were found to be significantly associated with the dislodgement of sealants. Conclusions: At 12 months follow-up, the retention of bonded amalgam sealant (BAS) was significantly lower than that of the resin-based sealant (RBS)

Evaluation and Optimization of Prolonged Release Mucoadhesive Tablets of Dexamethasone for Wound Healing: In Vitro-In Vivo Profiling in Healthy Volunteers

The aim of the projected study was to design and develop a novel strategy for evaluating the mucoadhesive potential of polymeric tablets of dexamethasone (DXM) for local delivery against wounds. Therefore, formulations (Q1-Q7) were synthesized via direct compression method by varying the concentrations of polymers, i.e., ethyl cellulose (EC) and agar extract (AG). Moreover, the mucoadhesive polymeric tablets were characterized via physicochemical, in vitro, ex vivo and in vivo experiments. However, physicochemical characteristics such as FTIR showed no interaction with different polymeric combination. Surface pH of all formulations was normal to slightly alkaline. Highest hydration of up to 6.22% and swelling index was comprehended with maximum concentration of AG (50% of total tablet weight). Whereas, ex vivo and in vivo residence time and mucoadhesion were attributed to the increased concentrations of polymers. Moreover, Q7, (optimized formulation), containing 10% of EC and 40% of AG, exhibited maximum release of DXM (100%) over 8 h, along with sufficient mucoadhesive strength up to 11.73 g, following first-order kinetics having r(2) value of 0.9778. Hemostatic effects and epithelialization for triggering and promoting wound healing were highly pronounced in cases of Q7. Furthermore, in vivo residence time was 7.84 h followed by salivary drug concentration (4.2 mu g/mL). However, mucoadhesive buccal tablets showed stability for 6 months, thus following the standardization (ICH-Iva) stability zone. In summary, DXM mucoadhesive tablets seem to be an ideal candidate for eradication of wound infections via local targeted delivery

Pathophysiological characterization of asthma transitions across adolescence

BACKGROUND: Adolescence is a period of change, which coincides with disease remission in a significant proportion of subjects with childhood asthma. There is incomplete understanding of the changing characteristics underlying different adolescent asthma transitions. We undertook pathophysiological characterization of transitional adolescent asthma phenotypes in a longitudinal birth cohort.METHODS: The Isle of Wight Birth Cohort (N = 1456) was reviewed at 1, 2, 4, 10 and 18-years. Characterization included questionnaires, skin tests, spirometry, exhaled nitric oxide, bronchial challenge and (in a subset of 100 at 18-years) induced sputum. Asthma groups were "never asthma" (no asthma since birth), "persistent asthma" (asthma at age 10 and 18), "remission asthma" (asthma at age 10 but not at 18) and "adolescent-onset asthma" (asthma at age 18 but not at age 10).RESULTS: Participants whose asthma remitted during adolescence had lower bronchial reactivity (odds ratio (OR) 0.30; CI 0.10 -0.90; p = 0.03) at age 10 plus greater improvement in lung function (forced expiratory flow 25-75% gain: 1.7 L; 1.0-2.9; p = 0.04) compared to persistent asthma by age 18. Male sex (0.3; 0.1-0.7; p &lt; 0.01) and lower acetaminophen use (0.4; 0.2-0.8; p &lt; 0.01) independently favoured asthma remission, when compared to persistent asthma. Asthma remission had a lower total sputum cell count compared to never asthma (31.5 [25-75 centiles] 12.9-40.4) vs. 47.0 (19.5-181.3); p = 0.03). Sputum examination in adolescent-onset asthma showed eosinophilic airway inflammation (3.0%, 0.7-6.6), not seen in persistent asthma (1.0%, 0-3.9), while remission group had the lowest sputum eosinophil count (0.3%, 0-1.4) and lowest eosinophils/neutrophils ratio of 0.0 (Interquartile range: 0.1).CONCLUSION: Asthma remission during adolescence is associated with lower initial BHR and greater gain in small airways function, while adolescent-onset asthma is primarily eosinophilic.</p

A Theoretical Model for Predicting Axial Compressive Strain of FRP-Confined Concrete

The axial compressive strength and strain of structural elements made of reinforced concrete are enhanced by the external confinement provided by fiber-reinforced polymer (FRP) sheets. There is still a need for more research into estimating axial compressive strain even though numerous studies have suggested analytical approaches to predict the axial compressive strength of concrete structural elements. This is a result of earlier strain models’ inadequate accuracy. Furthermore, rudimentary modelling techniques and small, noisy databases were used in the development of these models. To suggest a more realistic strain model and compare it with earlier models, a more rigorous methodology is therefore required. The goal of this study is to present a strain model for FRP-confined concrete members by analytical modeling based on a large database containing 570 sample points. When the models were assessed using statistical parameters, it was discovered that the estimations of the freshly proposed models were more accurate than those of the previous models. The estimations’ relative study provides significant support for the recommended analytical model’s applicability and accuracy in forecasting the axial-strain of CFRP-confined concrete compression members
