The purpose of this study was to assess the self-perceived need, seeking and use of dental care and its main determinants in Kurdistan province, Iran.

A total of 1,056 adults in Kurdistan province were included in this cross-sectional study. Multistage sampling approach was used to select the samples. Data on sociodemographic characteristics, economic status, self-perceived need, seeking and use of dental care were collected using a self-administrated questionnaire. Multivariate logistic regression model was used to assess factors affecting the use of dental care. In addition, socioeconomic inequality relating to dental care needs and use of dental care were examined using concentration curve and concentration index.

In this study, unmet dental care need was 62.7%. There was a perceived need for dental care among 13.7% (n = 145) of the participants in the past month, with only 39.3% (n = 57) seeking the care. The most important reasons for unmet dental care need were “Could not afford the cost” and “Insurance did not cover the costs.” Multivariate logistic regression showed that supplementary insurance status and household economic status were identified as main determinants affecting dental care-seeking behavior. The result of concentration index revealed that seeking dental care was more concentrated among the rich, whereas the perceived dental care need is more prevalent among the poor.

This study demonstrated that the prevalence of unmet dental care needs is high in the study setting. Also, financial barrier was identified as the main determinant of unmet dental care needs.

The extant literature on lean service reveals a noticeable lack of theoretical models establishing the core constructs of lean service, their interrelation and impact on organizational performance. The purpose of this paper is to address this gap by proposing a theoretical model in which lean constructs are identified and operationalized to establish their interrelation and impact on organizational performance.

This paper synthesizes information drawing on a systematic review of the literature on lean service, other relevant academic literature to develop a theoretical model and a set of propositions. Drawing on the universal theory, socio-technical systems theory and contingency theory (CT), the paper highlights and clarifies the potential impact of lean service on operational and financial performance.

This study identifies a comprehensive set of lean technical practices, lean supportive practices, inhibitors and expected outcome of lean service. Expected relationships among those constructs are established by developing a conceptual framework with several propositions based on the relevant literature and the socio-technical system theory, the universal perspective and the CT, when relevant. Moreover, six influential contextual variables on the lean-performance relation are identified based on a review of the management accounting literature, organizational strategy literature and diversification literature to overcome limitations of previous studies.

This paper covers a gap in the literature by identifying and operationalizing lean service constructs and offering a theoretical model with several propositions that establish relationships between lean constructs and overcome limitations in previous studies by identifying six contextual variables that are important factors in the lean-performance associations.

Life experience in hot and arid areas of Iran has proved that in the transitional seasons (spring and autumn) in which the climate is not too hot, passive cooling systems such as windcatchers (baadgir) have functioned well. This paper intends to investigate the efficiency of a single-side windcatcher as a passive cooling strategy; the case study is the Bina House windcatcher, located in Khousf town, near Birjand city, Iran.

To achieve the aim, air temperature, relative humidity, wind data and mean radiant temperature were measured by the related tools over five days from September 23 to October 23. Then, the thermal performance of the windcatcher was examined by analyzing the effects of all these factors on human thermal comfort. Quantitative assessment of the indoor environment was estimated using DesignBuilder and its computational fluid dynamics (CFD) tool, a thermal comfort simulation method to compare the cooling potential of the windcatcher. Windcatcher performance was then compared with two other common cooling systems in the area: single-side window, and evaporative cooler.

The results showed that both windcatcher and evaporative cooler can provide thermal comfort for Khousf residents in the transitional seasons; but the difference is that an evaporative cooler needs to consume water and electricity power, while a windcatcher is a passive cooling system that uses clean energy of wind.

The present study, by quantitative study of single-side windcatchers in a desert region, measured the climatic factors of a historical house and compared it with thermal comfort criteria. Therefore, the results of field measurements were analyzed, and the efficiency of the windcatcher was compared with two other cooling systems, namely single-side ventilation and evaporative cooler, in the two seasons of summer and autumn (transition seasons).

Assessing the outcome of lean transformation journey has been of interest to both researchers and practitioners. Various qualitative and quantitative assessment methodologies have been proposed in literature to track and measure the degree of leanness attained. The purpose of this paper is to understand the evolution of this leanness assessment literature over different attributes and identify gaps for future research.

A detailed literature review of peer-reviewed journal articles and conference papers addressing leanness assessment was performed. Content analysis methodology involving a four-step process suggested by Mayring (2004) was adopted for this study.

The number of studies in literature on leanness assessment is low when compared to that in the area of lean implementation. Assessment methodologies developed are of wide range, varying from simple qualitative checklist to complex quantitative mathematical models. Following the trend of lean implementation literature, lean thinking assessment literature is also getting transformed from process-level monitoring to enterprise-level monitoring. Finally, based on this review, a simplified leanness assessment framework is proposed for future validation.

Only peer-reviewed journals and conference papers were analyzed, while excluding the manuals, reports, and white papers from practice. Clustering of leanness assessment literature revealed that future studies in this domain would fall into two major categories, namely manufacturing leanness assessment and service leanness assessment.

Practitioners can use this review study to choose a suitable methodology for assessing the leanness attained in their organization by controlling for the structural attributes identified.

This is the first paper to review the topic “leanness assessment.” The review analyzes the entire literature available on leanness assessment to summarize its current status and identify potential future directions.
