title: Diffusion of operational capabilities knowledge: The social skills perspective

description: Abstract Paper aims This paper aims to understand how the social skill of managers influence the diffusion of operational capabilities in food and auto parts manufacturing networks. Originality There are taken-for-granted beliefs that its diffusion is based on replicating or transferring resources and practices from one site to another. This study is one of the first ones to discuss operational capability and socially skilled actors. Research method Two polar cases were analyzed through the Strategic Action Fields perspective based on a qualitative perspective and 17 in-depth interviews. Main findings Results demonstrate that diffusion of capability among various actors in subsidiaries will depend on a series of multidimensional factors that influence this process as the stability, state, and relationship between fields. Moreover, members tend to adopt a logic (perception of the world) that reflects the point of view of the group, and from this, the actors construct their narratives, recognize the legitimacy and justify their actions. Implications for theory and practice These perspectives have scarcely been explored in Operations management till today and shall open a new dialogue between Operations Strategy and Organization Studies. It offers practical guidance for diffusing and deploying operational capabilities.

title: Replication data for: The Role of Non-Contributory Pensions on Internal Mobility in Spain

description: To study the impact of non-contributory pensions on mobility decisions of working-age individuals we gather data from a variety of sources. The individual level data come from the 2nd quarters of the Spanish Labor Force Survey (Encuesta de Poblaciόn Activa, EPA, Spanish Statistical Institute, 2017a), which provides labor market status and province of residence at the time of the survey, t+1, as well as one year before, at time t. Information on migratory flows between provinces is gathered from the Residential Variations Statistics (Estadistica de Variaciones Residenciales, EVR, Spanish Statistical Institute 2017b). As noted earlier, we use the 1988 flows to weigh average provincial traits based on the relevance of the alternative locations, which include all other provinces, in that base year. Our key regressor is the share of the province’s population that are old-age non-contributory pensioners, which we gather from the Labor Statistics Yearbook of the Employment and Social Security Ministry (2017) and from the Population Statistics of the Spanish National Statistical Institute (2017c). We compile information on the number of beneficiaries of the so-called assistance pensions (from the 1981 Law) and the more recent non-contributory pensions (implemented by the 1991 Law). <br>We also gather data from various sources to account for the role played by the province’s economy, labor and housing markets, and its population composition. Annual provincial employment rates capturing changes in labor market conditions are derived from the Spanish National Statistics Institute (2017d). The share of the population 65 plus over total provincial population is also obtained from the Spanish National Statistics Institute (2017c). We include controls for the share of the province’s population earning unemployment benefits (computed using the Encuesta de Población Activa, EPA). Lastly, in our robustness checks, we experiment with including data on the employment share in the construction sector from the Spanish National Statistics Institute (2017d), the share of the population 65 years of age and above with a primary education or less (also computed using the Encuesta de Población Activa, EPA), provincial housing prices gathered from the Spanish Ministry of Development (Ministerio de Fomento, 2017), as well as provincial per capita GDP, which we deflate, along with its housing prices, using the province’s consumer price index are gathered from the Instituto Nacional de Estadistica (2017e).<br>See references in the main paper<br>

title: Economic and environmental sustainability dimensions of a fashion supply chain: A quantitative model

description: Abstract Paper aim The paper presents a model to assess the economic and the environmental sustainability dimensions of a fashion supply chain and tests it on a company. Originality The gap intended to fill is the lack of models in this context having this purpose, and, in general, the necessity to develop models and metrics allowing to quantitatively assess the economic and environmental dimensions of supply chains. Research method The fashion supply chain has been divided into five processes. Hence, an analytic model was developed by considering the total costs incurring in each process (economic evaluation), and the annual kilograms of CO2 emitted (environmental perspective). The model was then applied to a case study. Data was obtained from interviews with the management. Main findings Results show that from the economic perspective supply impacts the most, while from the environmental one the most polluting activity is production. Implications for theory and practice The model is easy to apply and to understand and allows to identify the activities in the supply chain where the majority of costs/emissions are generated. It is therefore expected to be useful for undertaking operational decisions aimed at decreasing the economic or environmental impact of a fashion supply chain.

title: Method for assessing the obsolescence of manufacturing equipment based on the triple bottom line

description: Abstract Paper aims This paper proposes a method for the assessment of equipment obsolescence, which includes the economic, environmental and social dimensions that compose the triple bottom line. Originality This paper describes a novel method that allows a complete evaluation of the state of use of a machine, besides the traditional economic-functional analysis, as well as its application in a large electric machines manufacturing company. Research method Analytic Hierarchy Process (AHP) multicriteria analysis is used, allowing a comparative and flexible assessment of the equipment. Main findings Even if there is no economic justification for replacing the equipment considering the financial return on investment, the machine can be considered obsolete from a sustainable point of view, due to its inadequate environmental and social performance. Implications for theory and practice Applying sustainability concepts in the manufacturing environment, more precisely in the machines on the shop floor, is very important to ensure cleaner production.

title: Role of Twist and Podoplanin in Partial Epithelial-Mesenchymal Transition in Oral Squamous Cell Carcinoma

description: Abstract The aim of this study was to perform a comparative analysis of podoplanin (PDPN) and Twist immunoexpressions in lower lip and oral tongue squamous cell carcinomas (LLSCC and OTSCC, respectively). PDPN and Twist immunoexpressions were semi-quantitatively evaluated by analyzing the invasion front, the compressive areas, the large islands and nests and dissociated cells of the chosen carcinomas. Their statistical associations and correlations with clinical-pathological characteristics were verified by the Mann-Whitney and Spearman’s test. Twist expression was low in both carcinomas, with &lt;25% labeling on the invasive front. Significant differences were observed for LLSCC (p=0.032) and OTSCC (p=0.025) regarding PDPN immunoexpression in relation to the worst invasion patterns determined by a histological malignancy gradation system. Statistically significant negative correlations between PDPN membrane expression and general (r=-0.356, p=0.024) and cytoplasmic Twist expressions (r=-0.336; p=0.034) in LLSCC were also observed. Twist and PDPN are suggested to be associated to a more aggressive invasion pattern in both LLSCC and OTSCC cases but not related to the different biological behaviors on these anatomical sites. Also, it was seen that PDPN membrane expression is inversely related to general and cytoplasmic Twist expression in LLSCC cases.

title: Simulation-based analysis of lean practices implementation on the supply chain of a public hospital

description: Abstract Paper aims This article aims to evaluate the impact of Lean Production (LP) practices implementation on the supply chain of a public hospital. Originality Most implementations fall short of their goals because they are done in a fragmented way and not from a system-wide perspective. Our approach allows to anticipate errors of misguided LP implementations in healthcare organizations. Research method The implementation of a set of LP practices in the hospital`s supply chain was assessed by computational simulation modelling, focusing on one of the most financially important product families. Main findings Since the simulation model considers the variability of suppliers and customers as inputs, it allows the verification of the proposed inventory policies effectiveness, in order to avoid affecting the service level. Implications for theory and practice The proposition of a method that integrates value stream mapping into computational simulation modelling brings a differentiated approach to analyze lean implementation in a healthcare supply chain. The simulation model supports a more assertive decision-making process on lean implementation, allowing the organization to ensure that the quality and efficiency of healthcare is not affected.

title: Anti-Micro RNA-221 a Promising Genetic Therapy of Oral Squamous Cell Carcinoma (SCC-25)

description: Abstract Micro-RNA-221(miR-221) is one of oncogenic miRNAs that plays a vital role in the development and progression of oral cancers. The aim of this study is to introduce a new gene therapy for oral squamous cell carcinoma by blocking the expression of oncogenic miR-221 by its inhibitor. The present work was performed on squamous cell carcinoma cell line SCC-25 and anti-miR-221 was delivered to the cells using an ultrasound micro bubbles. Assessment of the effect of miR-221 inhibitor on SCC-25 cells was done using MTT assay, cell cycle analysis and apoptosis detection. In addition, reverse transcription-polymerase chain reaction was also used to detect the expression -miR-221 and its target genes. Using ANOVA, statistical analysis of the results showed significant inhibition of cell viability with and induction of cell apoptosis of SCC-25 cell line after transfection. Moreover, the expression of miR-221, Epidermal growth factor receptor (EGFR) and CDKNIB/p27 were downregulated without significant difference. Transfection of SCC-25 by inhibitor of miR-221 resulting in blockage of its expression leading to arresting of tumor growth. These results proved the effective role of micro-RNA inhibitors as novel therapeutic agent for oral cancers.

title: Extending the POLCA production control system with centralized job release

description: Abstract Paper aims POLCA is a production control system that forwards to gateway manufacturing cells jobs that arrive to a manufacturing system. However, Workload Control literature shows benefits from using a centralized release pre-shop pool. Thus, the paper aims at investigating the performance impact of incorporating centralized job release into POLCA, in high-variety make-to-order production. Originality This has not been investigated before. Research method Simulation was used for experimentation. Main findings In the case of the general flow shop, a manufacturing system configuration aligned with many real-world production systems, the investigation shows that adding centralized job release to the POLCA system, together with job release based on job workload, leads to a markedly improvement of job delivery performance. Implications for theory and practice The results show theoretical and practical relevance of applying central job release to POLCA system, in high-variety production, due to its markedly positive impact on delivery performance.

title: Jaffe-Lichtenstein Syndrome Associated with a Simple Bone Cyst: Unprecedented Rare Case Report

description: Abstract Lesions denominated fibro-osseous lesions of the jaw constitute a diversified group of disorders, in which the normal bone architecture is replaced by fibroblasts, collagen fibers and immature bone. At present, the World Health Organization recognizes four variants of these lesions, namely: bone-cement dysplasia, fibrous dysplasia, ossifying fibroma and Familial gigantiform cementoma. Fibrous dysplasia may present in the monostotic form, affecting one single bone or an isolated craniofacial region; and in the Polyostotic form, involving two or more bones of the skeleton, and eventual association with syndromic conditions. The patient, C.P.G., 43 years old, sought attendance due to symptomatic increase in the region of the mandibular body on the right side. Imaging exams revealed craniofacial areas with ground-glass aspect, beyond the extensive mandibular radiolucent lesion. During the physical exam, spots of the Café au lait type disposed on the right side of the body were identified, in addition to uncoordinated gait with distinct shortening of the right leg. Additional radiographic exams showed evidence of skeletal dissemination of the disease. The patient denied any sexual precocity, and the final diagnosis was fibrous dysplasia, expressed by means of the Jaffe-Lichtenstein syndrome, in association with a simple bone cyst.

title: Potential of a New Cone-Beam CT Software for Blooming Artifact Reduction

description: Abstract This study evaluated the dimensions of intraradicular posts using a new cone beam CT (CBCT) software, and verified the potential of blooming artifact reduction. Sixty-three single-rooted human teeth were shaped, obturated, prepared for intracanal post placement and distributed into three groups: G1: anatomically customized prefabricated glass fiber posts; G2: low-fusion alloy posts; G3: gold alloy posts. After post fabrication and luting with RelyX U200®, specimens were sectioned axially at 9 mm from the root apex, and markings were made on the root surfaces (X-, Y- and Z-axes). The dimensions of the original posts (control group) were measured using a digital micrometer. CBCT scans of the teeth were obtained using a PreXion 3D Elite® scanner. Posts were measured on CBCT scans using DICOM files and the e-Vol DX software. A specific filter, Blooming Artefact Reduction (BAR), was developed to analyze intracanal posts. Statistical data were evaluated using the Van de Waerden nonparametric analysis of variance and, after that, normalized data were analyzed using the Tukey test. The level of significance was set at α = 5%. The measures of the anatomical prefabricated, low-fusion alloy and gold alloy intracanal posts obtained using the e-Vol DX CBCT software and a micrometer were not significantly different (p&gt;0.05). The use of the BAR filter of the e-Vol DX software application did not induce any dimensional differences on CBCT scans of intracanal posts when compared with measurements made with a micrometer on original posts. The use of the BAR filter eliminated blooming artifacts.

title: Comparative Effects of CPP-ACP and Xylitol F-Varnishes on the Reduction of Tooth Erosion and Its Progression

description: Abstract Evaluated the effect of CPP-ACP/NaF and xylitol/NaF varnishes in reduce erosion and progression of erosion. Forty enamel blocks were divided into four groups (n=10): G1=CPP-ACP/NaF varnish (MI varnishTM); G2=xylitol/NaF varnish (Profluorid®); G3=NaF varnish (Duraphat®, positive control) and G4=deionized water (MilliQ®, negative control). Samples were immersed in Sprite ZeroTM (pH 2.58, 4x/day, 3 days), in between immersions, the specimens stayed in artificial saliva. After 3 days of erosion, the eroded area was divided in two (half of one received an additional varnish layer while the other half repeated the same 3-day erosion cycle). The 3D, non-contact profilometry technique was used to determinate tooth structure loss (TSL) and surface roughness (SR). Scanning electron microscopy (SEM) and 3D images were utilized to evaluate the topography of the samples. Mann-Whitney, one-way ANOVA and Tukey tests were used (significance level of 0.05%). SEM and 3D images were descriptively evaluated. After 3 or 6 days of erosion, all tested varnishes were better than G4 (p&lt;0.05) for TSL and SR. In addition, G1 had lower values for TSL than G3 (p&lt;0.05) after 3 days of erosion. Under SEM and 3D images observation, all groups presented porosity, irregularities and depressions on the surface enamel after 3 and 6 days of erosion, more pronounced in G4. An application of topical NaF varnishes was effective in reducing TSL and enamel roughness after erosion challenges, being the CCP-ACP/NaF varnish more effective than NaF varnish and water after 3 days of erosion.

title: Dental Fear in Children: Association with Dental Caries and Molar Incisor Hypomineralization

description: Abstract The aim of this study was to investigate the prevalence of dental fear and to evaluate its association with dental caries and molar incisor hypomineralization (MIH) in schoolchildren aged 8-10 years from a municipality in Northeastern Brazil. Data from 466 students enrolled in urban public schools in a cross-sectional study were collected. Parents/guardians answered a questionnaire addressing sociodemographic characteristics, dental fear was measured by means of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS) and clinical examinations were performed by three calibrated examiners for diagnosis of dental caries, using the International Caries Detection & Assessment System - ICDAS II and a previously validated index for MIH. Descriptive data analysis was performed, and associations between dental fear, dental caries and MIH were analyzed using robust Poisson regression for complex samples (p&lt;0,05). The prevalence of dental fear was 21.6%, and the mean total CFSS-DS score was 29.97 (CI 95%=29.05-30.89). In the multivariate adjusted model, the prevalence of dental fear was associated to family income (PR=1.78; CI 95%=1.02-3.08; p= 0.041). Monthly family income was associated with dental fear in children, whereas dental caries and MIH were not associated with dental fear.

title: Survival of Dental Implants in Oncology Patients versus Non-Oncology Patients: A 5-Year Retrospective Study

description: Abstract Patients with a history of cancer are increasingly common in the dental office. Treating cancer patients requires a multidisciplinary team, which should include the dentist, in order to control the complications that occur in the oral cavity and also to recover the patient undergoing treatment in any of its types: surgical, medical, radiotherapeutic, or its possible combinations. Dental implants can be a safe and predictable treatment option for prosthetic rehabilitation. The aim of this paper is to describe in retrospect the success rate of osseointegrated implants in oncology and non-oncology patients placed by the Master of Dentistry in Oncology and Immunocompromised Patients, as well as the Master of Medicine, Surgery and Oral Implantology of the University of Barcelona Dental Hospital, between July 2011 and March 2016. 466 patients were reviewed, with a total of 1405 implants placed, considering the oncological history of the patients and the implant success rate. The total success rate in the concerned period was 96.65%. When comparing cancer patients with healthy ones, the success rate has been 93.02% in the first case, and 97.16% in the latter. According to the literature review, our results encourage implant placement in cancer patients, it is important to recognize that this is an analysis of a complex care pathway with a large number of confounding variables. However, the findings should not be considered as generalizable.
