Performance management practices in lean manufacturing organizations: A systematic review of research evidence

This paper provides the first systematic look into the existing research on performance management (PM) practices employed in lean manufacturing organisations (LMOs). It adopts a systematic review method to examine the evidence generated in the period 2004 – 2015 and uses a comprehensive PM framework to synthesise the findings. The results suggest that PM practices that have the most prominent role in LMOs are those that, firstly, are located closest to front-line actions and, secondly, explicitly address operational realities. This calls into question the primacy of accounting-driven controls in LMOs, suggesting that operational controls may be more effective than top-down accounting-based PM practices. The results also confirm the bias towards operational-level issues but suggest that LMOs may integrate the operational and the strategic levels by using PM practices that drive organisational learning through employee involvement and engagement

Light-curing process for clear aligners’ attachment reproduction: comparison between two nanocomposites cured by the auxiliary of a new tool

BACKGROUND: Attachments’ configuration play an important role during Clear Aligner Treatment (CAT) for aligner retention and control of movements planned. The aims were to compare the macroscopic morphology of attachments reproduced with flowable (FNC) and conventional (CNC) composites and the effects on them of two light-guide tips with different dimensions. METHODS: 4 resin casts derived from the initial scan of the same patient were obtained. 10 vestibular attachments were replaced on both upper and lower arches of each model with CNC (Models A, B) and FNC (Models C, D). Each composite was cured by means of the same LED lamp with both regular light-guide (Models A, B) and push and light tool® (Models C, D). The 80 attachments were qualitative analyzed by means of a digital stereo microscope. Surface roughness and waviness measurements were assessed by contact probe surface profiler (TalySurf CLI 2000; Taylor Hobson, Leicester, United Kingdom). Statistical analysis was performed with independent samples t-tests. Significance was established at the P < 0.05 level. RESULTS: Model A showed lower values of surface roughness (Ra − 1.41 µm, Rt − 3.46 µm) and waviness (Wa − 2.36 µm, Wt − 10.95 µm) when compared with Model C. Significant reduction of waviness (Wa − 3.85 µm, Wt − 4.90 µm) was observed on Model B when compared with Model D. Significant increase of roughness and waviness parameters (Ra 3.88 µm, Rt 21.07, Wa 2.89 µm, Wt 14.74 µm) was found when CNC sample (Model A) was cured with regular light-guide tip. Higher values (Ra 2.33 µm, Rt 24.07 µm, Wa 1.67 µm, Wt 20.79 µm) were observed after regular light-guide tips curing on FNC sample (Model C). CONCLUSIONS: CNC resins determine more regular surfaces of attachments profiles. The additional use of a smaller light- guide of the LED push and light tool® allows to improve the macroscopic morphology of the attachments and to maximize light irradiance delivering by enhancing the polymerization process and the integrity of the features during the treatment

The role of performance measurement in aligning operations with strategy: Sustaining cognitive processes of internal alignment

Purpose: This paper addresses an important theoretical shortcoming in the conceptualization of internal alignment by investigating the cognitive processes involved in aligning operations with strategy and the role of performance measurement (PM) in sustaining these processes. Design/methodology/approach: A theory-building study investigates the process of using PM to drive the implementation of a new strategy in a large beer manufacturer in Italy. The study employs a sensemaking perspective to theorize the findings. Data were collected through semi-structured interviews, field observations, and company documents. Findings: This study develops a theoretical model suggesting that establishing and maintaining internal alignment occurs through seeking, assembling, adjusting, and finalizing the meaning of how strategic priorities inform local action. PM plays a central role in this process by providing interpretive support. Research implications: This article advances a cognition-centered view of internal alignment that complements the behavioral aspect of the phenomenon emphasized in prior literature. Practical implications: Using PM for aligning operations with strategy is a complex and iterative process that requires time and effort and generates temporary stability. Managers may need to complement traditional approaches to alignment with providing space for sensemaking. Originality/value: The paper proposes a view of internal alignment as an ongoing interpretive process that is sustained by PM. This process brings about the consistency of meanings that generates strategy-consistent behaviors

Performance measures for endoscopic retrograde cholangiopancreatography and endoscopic ultrasound: A European Society of Gastrointestinal Endoscopy (ESGE) Quality Improvement Initiative

The European Society of Gastrointestinal Endoscopy (ESGE) and United European Gastroenterology present a short list of key performance measures for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP). We recommend that endoscopy services across Europe adopt the following seven key and one minor performance measures for EUS and ERCP, for measurement and evaluation in daily practice at centre and endoscopist level: 1 Adequate antibiotic prophylaxis before ERCP (key performance measure, at least 90%); 2 antibiotic prophylaxis before EUS-guided puncture of cystic lesions (key performance measure, at least 95%); 3 bile duct cannulation rate (key performance measure, at least 90%); 4 tissue sampling during EUS (key performance measure, at least 85%); 5 appropriate stent placement in patients with biliary obstruction below the hilum (key performance measure, at least 95%); 6 bile duct stone extraction (key performance measure, at least 90%); 7 post-ERCP pancreatitis (key performance measure, less than 10%); and 8 adequate documentation of EUS landmarks (minor performance measure, at least 90%). This present list of quality performance measures for ERCP and EUS recommended by the ESGE should not be considered to be exhaustive; it might be extended in future to address further clinical and scientific issues

Trend in potassium intake and Na/K ratio in the Italian adult population between the 2008 and 2018 CUORE project surveys

Abstract Background and aims Low potassium intake, in addition to high sodium, has been associated with higher risk of hypertension and CVD. The Study assessed habitual potassium intake and sodium/potassium ratio of the Italian adult population from 2008 to 2012 to 2018–2019 based on 24-h urine collection, in the framework of the CUORE Project/MINISAL-GIRCSI/MENO SALE PIU' SALUTE national surveys. Methods and results Data were from cross-sectional surveys of randomly selected age-and-sex stratified samples of resident persons aged 35–74 years in 10 (out of 20) Italian regions. Urinary electrolyte and creatinine measurements were performed in a central laboratory. Analyses considered 942 men and 916 women, examined in 2008–2012, and 967 men and 1010 women, examined in 2018–2019. In 2008–2012, the age-standardized mean of potassium intake (urinary potassium accounts for 70% of potassium intake) was 3147 mg (95% CI 3086–3208) in men and 2784 mg (2727–2841) in women, whereas in 2018–2019, it was 3043 mg (2968–3118) and 2561 mg (2508–2614) respectively. In 2008–2012, age-adjusted prevalence of persons with an adequate potassium intake (i.e. ≥ 3510 mg/day) was 31% (95% CI 28–34%) for men and 18% (16–21%) for women; in 2018–2019, it was 26% (23–29%) and 12% (10–14%) respectively. The sodium/potassium ratio significantly decreased both in men and women. Conclusions The average daily potassium intake of the Italian general adult population remains lower than the WHO and EFSA recommended level. These results suggest the need of a revision to strengthen initiatives for the promotion of an adequate potassium intake at the population level

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
