    A Systemic Model for Managing and Evaluating Conflicts in Organizational Change

    Get PDF
    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

    Get PDF
    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

    Get PDF
    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

    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

    Get PDF
    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)

    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

    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

    Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

    Get PDF
    BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
