Does Web 2.0 utilisation lead to knowledge quality,improvisational creativity,compositional creativity,and innovation in small and medium-sized enterprises? A sense-making perspective

A few attempts were made to investigate how sense making is triggered through Web 2.0 utilisation and how it enables the accomplishment of key organisational outcomes. The objective of this research is to examine the structural relationship between Web 2.0 utilisation, knowledge quality (KQ) aspects, improvisational creativity, compositional creativity, and small and medium-sized enterprises (SMEs) innovativeness in an emerging market – Malaysia. Built upon sense-making theory, this study proposes that sense making is a progression of four formative constructs. Empirical analyses are based on a sample from SMEs’ top management (N?=?358, response rate?=?21%) using partial least squares approach. The findings indicate that Web 2.0 utilisation influences business entities’ sense-making activities in the way they realise the intrinsic value of knowledge and take action to apply the organisational knowledge. These sense-making activities are conducive to improvisational and compositional creativity of SMEs as well. Contributions, managerial implications, and limitations are discussed.     

Medical resource utilisation and healthcare costs in patients with chronic hepatitis C viral infection and thrombocytopenia

Abstract

Background:

Thrombocytopenia is a significant risk for patients with chronic HCV infection and a common side-effect of treatment with pegylated (PEG) interferon (IFN). Thrombocytopenia predisposes patients to bleeding and requirements for platelet transfusions, and may thus place an increased burden on patients and on medical resource utilisation.

Scope:

In a retrospective analysis of an integrated, longitudinal database of medical and pharmacy claims and laboratory results in a US commercial health (insurance) plan, patients with chronic hepatitis C viral (HCV) infection were identified by reviewing ICD-9-CM HCV-, chronic liver disease-, and cirrhosis-related diagnoses. Medical resource utilisation and laboratory results were evaluated during the year following the HCV diagnosis index date as well as during the baseline year prior to that index date. Medical resource utilisation was determined by comparing outpatient visits, emergency department (ER) visits, and inpatient hospital stays for HCV patients with or without thrombocytopenia.

Findings:

HCV patients diagnosed with thrombocytopenia had a greater incidence of bleeding events (27.3 vs. 9.9%), platelet transfusions (8.5 vs. <1%), liver disease-related ambulatory visits (10.4 vs. 4.4; odds ratio [OR]?=?2.3; p?<?0.001), ER visits (OR?=?8.6; p?<?0.01), and inpatient hospital stays (OR?=?17.7; p?<?0.01) during the study period compared with HCV patients without a thrombocytopenia diagnosis. HCV patients with thrombocytopenia had significantly higher overall healthcare costs ($37,924 vs. $12,174; p?<?0.001) and liver disease-related costs ($14,569 vs. $4107; p?<?0.001) than patients without thrombocytopenia.

Limitations:

Administrative claims data are subject to coding errors; additionally, the patient population may not be completely representative of the general chronic HCV population.

Conclusions:

Diagnosis of thrombocytopenia in patients with HCV is associated with increased incidence of certain comorbidities, complications, and medical interventions, and significantly increased medical resource utilisation.     

A tale of industrial stagnation from Africa

Many African economies have experienced rather dismal industrial development since the 1980s. The consensus is that African firms lack competitiveness in a world with increasing trade openness. What determines competitiveness? A well‐known explanation is that resource endowments in Africa favour land not labour, which results in high wages, especially in comparison with ‘labour abundant’ Asian economies. This paper examines the validity of this view on the basis of the case of Sudan. We demonstrate that the lack of competitiveness of manufacturing industries is not caused by high wages. Assuming a direct relationship between labour productivity and international competitiveness, we argue that acute capacity underutilisation, caused by supply‐side constraints, lowers manufacturing productivity, which in turn negatively influences competitiveness.     

Resource utilisation Efficiency: A South African Provincial Evaluation

The objective of this paper is to analyse the utilisation of production capacity and total under‐utilisation in order to identify weak‐performing industries across the nine South African provinces. Detecting inefficiencies within the different provinces will help to identify where sound managerial or government intervention is required, which can contribute to the future success of the New Growth Path Framework and the Strategic Integrated Projects. Using a multistage data envelopment analysis model at the subnational level, several categories of production factors are explored: intermediate demand, labour, capital, as well as taxes and subsidies. The results emphasise South Africa's weak infrastructure and the failure to effectively promote stability in managing factor inputs. The results further illustrate that industry scale efficiency for water and electricity are poorest across all provinces, highlighting the current water and energy supply concerns in South Africa and problem areas associated with the National Development Program.     

How do high-involvement work processes influence employee outcomes? An examination of the mediating roles of skill utilisation and intrinsic motivation

How do high-involvement work processes influence employee outcomes? In this paper, we use Vandenberg et al.'s [Vandenberg, R. J., Richardson, H. A., & Eastman, L. J. (1999). The impact of high involvement work processes on organisational effectiveness: A second order latent variable approach. Group and Organisational Management, 24, 300–339] elaboration of Lawler's [Lawler, E. E. (1986). High-involvement management: Participative strategies for improving organizational performance. San Francisco, CA: Jossey-Bass] model to test direct links and to explore skill utilisation and intrinsic motivation as mediators. Survey data were collected from a large New Zealand organisation providing distribution services and results were analysed through structural equation modelling. While there are important direct effects, the results demonstrate that both skill utilisation and intrinsic motivation transmit high-involvement processes into valuable outcomes for employees. The benefits to employees of such processes are direct but also lie in the way they make the work itself more motivating and enable them to deploy and grow their skills. This implies that forms of work organisation and supervision that offer workers greater opportunity for discretion, and involvement in the decisions that concern them, create the conditions for greater learning and, in turn, contribute to their well-being.     

TERRITORIAL PLANNING AND TOURISM DEVELOPMENT TAX

An economic model of land taxation involving a local government and a private developer constitutes the theoretical framework in this research. The model hinges around a two-tier approach including both a conservation and an efficiency criterion. The analysis indicates that sustainable tourism calls for the use of land taxation and planning legislation simultaneously geared to the achievement of efficiency and the signaling of the government’s commitment to conservation policies. To provide support for the theoretical conclusions, an Italian case study is discussed, showing how the local government chose not to yield to a developer’s requests by not changing a norm prohibiting construction near of the coastline.     

A case-control study of anaemia in patients with rheumatoid arthritis treated with disease-modifying antirheumatic drugs in an adult population in the US: prevalence and impact on healthcare utilisation

Abstract

Objective: The objective of this study was to estimate the prevalence of anaemia and its impact on healthcare utilisation in patients with rheumatoid arthritis (RA).

Methods: Patients with claims for moderate-to-severe RA (ICD-9 code 714.x) treated with disease-modifying antirheumatic drugs as well as controls without RA matched for age, gender and time in plan were selected from the MarketScan Research Database. Anaemia was identified by ICD-9 codes 280.x, 285.2x, 281.9, 285.9 and 284.8. The prevalence ratio and 95% confidence interval (CI) for anaemia among RA patients versus controls were estimated. Overall disease burden was measured using the Elixhauser Comorbidity Index (ECI).

Results: The prevalence ratio for anaemia in RA patients was 2.2 (95% CI 2.1–2.4). Mean ECI was higher in RA (2.26) compared with control (1.02) patients (p<0.001), and RA patients with anaemia had a higher ECI compared with those without anaemia (3.95 vs. 2.08; p<0.001). Total healthcare costs in RA patients with anaemia were approximately twice those of RA patients without anaemia.

Conclusions: The prevalence of clinically diagnosed anaemia in RA patients in the claims database was 2.2 times higher than that in the comparable non-RA control group. RA patients with anaemia had significantly higher levels of co-morbidity and healthcare costs than RA patients without anaemia.     

Tracing the utility of injury surveillance data in Pretoria (South Africa) and Borås (Sweden)

Our research attempted to study the factors that influenced the use of injury data in two cities, representing different injury and socio-economic profiles. In Pretoria, the South African capital city, injury data uptake was constrained by, among other factors, the transitional institutional environment, stakeholders' suspicion of research and the absence of safety promotion champions. In the Swedish city of Borås, injury data uptake was facilitated by well-established research agency–municipality partnerships, injury prevention champions, a receptive political and knowledge driven environment and dedicated resources. The study signified the role of a range of content issues, contextual arrangements, social actors who may or may not operate from a perspective of sufficient consensus and institutional communication processes that may either facilitate or hinder the multiple employment and rapid movement of data along the ‘ladder of knowledge utilisation’. Safety promotion researchers may need to expand their roles beyond data production to improve data utility.     

Impact of ocular symptoms on quality of life (QoL), work productivity and resource utilisation in allergic rhinitis patients – an observational,cross sectional study in four countries in Europe

Abstract

Objective:

It is hypothesised that the presence of ocular, in addition to nasal, symptoms among patients with allergic rhinitis (AR) results in poorer quality of life, reduced work productivity and increased resource utilisation. This study investigated the impact on quality of life, burden of illness and healthcare resources among 1640 AR patients.

Methods:

Data were drawn from an observational cross-sectional study of consulting patients undertaken in May/June 2008 in four European countries. Doctors provided records for the next four to five patients presenting with AR who filled out a self-completion survey which included the Work Productivity and Activity Impairment Allergic Specific Questionnaire (WPAI:AS), the Mini Rhinoconjunctivitis Quality of Life Questionnaire (RQOLQ) and the Pittsburgh Sleep Quality Index (PSQI). Propensity scoring allied to regression-type analysis was used to assess the extra burden associated with ocular symptoms utilising two comparison groups (patients with nasal-only symptoms versus those with nasal and ocular symptoms). The analysis controlled for differences between the groups on confounding variables age, gender, smoking status and co-morbidities. The analysis was conducted twice, once controlling for differences between the groups in nasal severity and once without, recognising that it is not clear whether or not increased nasal severity symptoms are naturally associated with ocular symptoms. The severity of ocular symptoms as opposed to their presence alone was also assessed on outcome measures using regression type methods.

Results:

A total of 1009 patient records met the inclusion criteria, of whom 69% presented with both ocular and nasal symptoms. The results show that the presence of ocular symptoms reduces quality of life, reduces work productivity and increases resource utilisation irrespective of whether differences in severity of nasal symptoms are accounted for between the comparison groups. Patients with nasal and ocular symptoms require more healthcare consultations. All work-related domains were statistically different, with the presence of ocular symptoms associated with greater impact on work hours missed and impairment while working. For each of the above this was the case regardless of whether or not adjustment was made for nasal severity (both p?<?0.05). Patients with nasal and ocular symptoms also record an additional half a day more time off work in the last 3 months as a result of AR (nasal severity unadjusted or adjusted, both p?<?0.05). Clinically meaningful differences were found in overall quality of life score as represented by RQLQ, with a mean score increase of 0.6 (nasal severity unadjusted) and 0.5 (nasal severity adjusted) associated with the presence of ocular symptoms (both p?<?0.05). With regard to sleep quality, the presence of ocular symptoms was associated with a mean increase in PSQI of 1 when no adjustment was made for nasal severity (p?<?0.05). When nasal severity was adjusted for, no significant difference was observed. Similarly, for the number of prescribed medications, when no adjustment was made for nasal severity, patients with ocular symptoms were observed to receive a significantly higher number of AR drugs (+0.19, p?<?0.05) whereas with nasal severity adjusted for the difference was +0.17 which was not significant. In addition, with the exception of the number of AR drugs prescribed, for all outcome variables, the severity of ocular symptoms, and not just their presence, had a detrimental impact on the outcome.

Limitations:

Since patients were recruited via the physician, the study aim was to represent the consulting population. In addition, it cannot be fully excluded that the likelihood for an individual patient to complete a questionnaire is influenced by differences in patient typology compared with those patients who chose not to complete. Given the geographical dispersion of the sample patients, it may be reasonable to assume possible differences in the intensity of the AR season based on latitude.

Conclusion:

The added presence of ocular symptoms in AR patients suffering with nasal symptoms deteriorates patients’ quality of life, leads to greater lost productivity and places higher burden on resource utilisation. Studies are therefore needed to test whether treatment options that address ocular in addition to nasal symptoms will improve quality of life and reduce both direct and indirect resource use associated with AR.
