From Business System to Supply Chain and Production in Japan. Lean production and its roots in Japanese business culture

2009

The Japanese business environment has been studied for many years by researchers and business operators from all over the world. The Japanese culture created a business climate that is different from other industrialized economies. Gerlach defined the Japanese economy as “alliance capitalism” , an expression, which better than others, represents the relational nature of the Japanese society and business system. It is not by chance that the manufacturing and management techniques, later defined as “lean” by MIT authors, were born and raised in Japan. In this dissertation I will attempt to explain why and how these approaches are linked with the Japanese culture and the Japanese business envi…

Socially desirable responding:enhancement and denial in 20 countries

2015

This article investigated the dimensionality, measurement invariance, and cross-cultural variations of social desirability. A total of 3,471 university students from 20 countries completed an adapted version of the Marlowe–Crowne scale. A two-dimensional structure was revealed in the pooled sample, distinguishing enhancement (endorsement of positive self-description) and denial (rejection of negative self-description). The factor structure was supported in most countries; medium-sized item bias was found in two denial items. In a multilevel analysis, we found that (a) there was more cross-cultural variation in denial than enhancement; (b) females tended to score higher on enhancement where…

Rpb4 and Puf3 imprint and post-transcriptionally control the stability of a common set of mRNAs in yeast

2020

ABSTRACTGene expression involving RNA polymerase II is regulated by the concerted interplay between mRNA synthesis and degradation, crosstalk in which mRNA decay machinery and transcription machinery respectively impact transcription and mRNA stability. Rpb4, and likely dimer Rpb4/7, seem the central components of the RNA pol II governing these processes. In this work we unravel the molecular mechanisms participated by Rpb4 that mediate the posttranscriptional events regulating mRNA imprinting and stability. By RIP-Seq, we analyzed genome-wide the association of Rpb4 with mRNAs and demonstrated that it targeted a large population of more than 1400 transcripts. A group of these mRNAs was als…

Drought-related cholera outbreaks in Africa and the implications for climate change: a narrative review.

2021

ABSTRACT Africa has historically seen several periods of prolonged and extreme droughts across the continent, causing food insecurity, exacerbating social inequity and frequent mortality. A known consequence of droughts and their associated risk factors are infectious disease outbreaks, which are worsened by malnutrition, poor access to water, sanitation and hygiene and population displacement. Cholera is a potential causative agent of such outbreaks. Africa has the highest global cholera burden, several drought-prone regions and high levels of inequity. Despite this, research on cholera and drought in Africa is lacking. Here, we review available research on drought-related cholera outbreak…

Relationship between resolution and accuracy of four intraoral scanners in complete-arch impressions

2018

Background The scanner does not measure the dental surface continually. Instead, it generates a point cloud, and these points are then joined to form the scanned object. This approximation will depend on the number of points generated (resolution), which can lead to low accuracy (trueness and precision) when fewer points are obtained. The purpose of this study is to determine the resolution of four intraoral digital imaging systems and to demonstrate the relationship between accuracy and resolution of the intraoral scanner in impressions of a complete dental arch. Material and methods A master cast of the complete maxillary arch was prepared with different dental preparations. Using four di…

Accuracy of four digital scanners according to scanning strategy in complete-arch impressions.

2018

STATEMENT OF PROBLEM:Although there are specific and general digital scanning guidelines depending on the system used, it is important to have the necessary flexibility in the acquisition of three-dimensional (3D) images to adapt to any clinical situation without affecting accuracy. PURPOSE:The purpose of this in vitro study was to identify and compare the scanning strategy with the greatest accuracy, in terms of trueness and precision, of four intraoral scanners in the impression of a complete dental arch. MATERIAL AND METHODS:Four digital scanners were evaluated with a 3D measuring software, using a highly accurate reference model obtained from an industrial scanner as a comparator. Four …

Comparative in vitro study of the accuracy of impression techniques for dental implants: Direct technique with an elastomeric impression material ver…

2019

Background The aim of this study was to compare a conventional technique (elastomeric impression material - EIM) and a digital technique (scanner digital model – SDM) on a six-analog master model (MM) to determine which was the most exact. Material and Methods Twenty impressions were taken of a master model (EIM) and twenty scanned impressions (SDM) (True Definition). A coordinate measuring machine (CMM) was used to measure the distances between adjacent analogues (1-2, 2-3, 3-4, 4-5, 5-6), intermittently positioned analogues (1-4, 3-6) and the most distal (1-6). Reference values were established from the master model, which were compared with the two impression techniques. The significance…

Mission Statements in Top Higher Education Institutions—What Do They Have in Common?

2021

The present paper envisages an analysis of the main goals and future directions of action in the higher education sector at world level. In recent years higher education institutions apply professional management principles and guide their activities using business specific strategic tools. Starting from the fact that higher education institutions can learn from the best, the purpose of the paper is to analyze the main directions included in the mission statements of the top 150 higher education institutions at world level, according to rankings. The two main objectives of the analysis are: (a) to identify the main directions included in the mission statements of the best universities in th…

Deliberate and Emergent Changes on a Way Towards Electronic Document Management

2011

A unit of Fortum Service Ltd. operates and maintains the Rauhalahti power plant in Central Finland. In 1996-97, the unit launched a project pursuing coordinated organizationwide electronic document management (EDM). This case follows deliberate and emergent changes related to document management in the organization since the initiation of the project until February 2000. New information technologies were adopted, and responsibilities for continuous improvement of EDM were assigned. The continuous improvement was implemented as an extension of the ISO 9002 quality system earlier adopted for process improvement. The case shows that a shift from the paper-based era towards organizationwide EDM…
