The implementation of digital technologies for operations management: a case study for manufacturing apps

Abstract

Manufacturing applications address business to business (B2B) with highly customised applications developed for specific requirements, offering highly specialised solution-oriented and service-based software components, systems, and digital tools that aim at a fast and accurate decision-making support system. The purpose of this paper is to describe the implementation of digital technologies for operations management using manufacturing or engineering apps (eApps), for product design and manufacturing processes. In particular, starting from the specific needs of two companies from mature European industries as automotive and food, this work depicts how this kind of solutions can support companies and improve their operations. In particular, related benefits and challenges faced for the full implementation of the developed tools are highlighted. Moreover a business model to exploit the manufacturing apps is also proposed. The business model proposed for the exploitation of the eApps supports the commercialisation of all the revenue streams offered by this rapidly growing sector taking into account the specific needs of the concerned stakeholders through a diversified value proposition.     

Differential Item Functioning of Pathological Gambling Criteria: An Examination of Gender, Race/Ethnicity, and Age

This study tested for the presence of differential item functioning (DIF) in DSM-IV Pathological Gambling Disorder (PGD) criteria based on gender, race/ethnicity and age. Using a nationally representative sample of adults from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), indicating current gambling (n = 10,899), Multiple Indicator-Multiple Cause (MIMIC) models tested for DIF, controlling for income, education, and marital status. Compared to the reference groups (i.e., Male, Caucasian, and ages 25–59 years), women (OR = 0.62; P < .001) and Asian Americans (OR = 0.33; P < .001) were less likely to endorse preoccupation (Criterion 1). Women were more likely to endorse gambling to escape (Criterion 5) (OR = 2.22; P < .001) but young adults (OR = 0.62; P < .05) were less likely to endorse it. African Americans (OR = 2.50; P < .001) and Hispanics were more likely to endorse trying to cut back (Criterion 3) (OR = 2.01; P < .01). African Americans were more likely to endorse the suffering losses (OR = 2.27; P < .01) criterion. Young adults were more likely to endorse chasing losses (Criterion 9) (OR = 1.81; P < .01) while older adults were less likely to endorse this criterion (OR = 0.76; P < .05). Further research is needed to identify factors contributing to DIF, address criteria level bias, and examine differential test functioning.

Ecological functions of an impounded marsh and three natural estuarine marshes along Woodbridge River,NY/NJ Harbor

An impounded estuarine marsh scheduled for restoration in 2003 and three nearby unimpounded marshes (Spartina alterniflora, S. patens/Iva frutescens, and Phragmites australis) in highly urbanized NY/NJ Harbor were studied to assess the impact of impoundment on marsh structure and function and to identify trajectories of ecosystem change following removal of the levee. Aboveground biomass was greater in the Phragmites and S. alterniflora marshes (706–809 g/m²) as compared to the S. patens/I. frutescens and impounded marshes (378–588 g/m²). Macro-organic matter (0–30 cm) was similar across all marshes (7452–9212 g/m²). The S. patens/Iva frutescens marsh had the lowest aboveground biomass, but contained more plant species (2.8 species/0.25 m²) and greater species diversity (H = 1.33) than the other marshes (1.3–2.0 species/0.25 m², H = 0.16–0.78). Rates of sediment and nutrient accumulation were lower in the impounded marsh (335 g sediment/m²/yr, 97 g C/m²/yr, 6.5 g N/m²/yr, and 0.9 g P/m²/yr) than in the reference marshes (422–1515 g sediment/m²/yr; 111–160 g C/m²/yr; 7–10 g N/m²/yr; 1.6–2.8 g P/m²/yr). Our results indicate that the impounded marsh does not contain the high species diversity of the high marsh, nor does it provide the same level of functions as naturally inundated marshes. Reintroduction of tidal inundation to the impounded marsh will enhance water quality benefits and favor development of S. alterniflora salt marsh community structure.     

Feeling safe in school∗

This paper advances the hypothesis that for a child to feel safe and to learn at school certain psychological conditions must be met. These conditions are described using concepts derived from psychoanalytic research and include; a background of SAFETY and a feeling of WELL BEING derived from a healthy ego with perceptual skills appropriate to the task, a HOLDING environment of adults who can respond appropriately to the child's developmental needs, an environment that provides CONTAINMENT and helps children process negativity in relationships, processes that help children regulate affect, value relationships, and leam to mentalise, in a SECURE ATTACHMENT experience, and finally, supports that encourage children to function as responsible members of a community organized as an OPEN SOCIAL SYSTEM.

Partner Appraisal and Marital Satisfaction: The Role of Self‐Esteem and Depression

This study examined whether people are more maritally satisfied when the valence of their partner's view of them is congruent with the valence of their self‐view. In doing so, competing hypotheses derived from self‐verification theory and self‐esteem enhancement theory were examined. Married couples, recruited from the community and mental health facilities, completed measures of marital satisfaction, self‐esteem, depression, and rated their spouse on a wide array of personality traits, both depressionrelated and depressionneutral. Regardless of self‐esteem and depression level, and across trait categories, targets were more maritally satisfied when their partners viewed them positively and less satisfied when their partners viewed them negatively. Thus, findings were inconsistent with self‐verification theory and consistent with a self‐esteem enhancement model.     

Cultural Access and Mental Health: An Exploratory Study

Loss of well-being, rising rates of depression and various psychological illnesses are a public health concern. This study aims to explore the associations between cultural access and mental illness. Applying a panel methodology to the 20 Italian regions (2002–2007 period) the relationship between public health expenditure per-capita (the dependent variable) and hospital discharge rates for different illnesses (the regressors) has been estimated. Then the impact of the private spending in culture (the regressors) on the mental illness—as approximated by the discharge rate for mental illness—(the dependent variable), has been verified via generalised method of moments (GMM) approach. Data came from the National Census of the Italian Institute of Statistics (ISTAT). The results of empirical analysis have highlighted how the discharge rate for mental illness is substantially improved by some forms of cultural consumptions. The coefficients associated with unemployment rates (the control variables) have a positive impact on mental illness, thus suggesting that unemployment has an impact on the discharge rate for mental illness; the greatest impact is observed for the long-term unemployment rate. The results are beneficial for designing and implementing preventive strategies to reduce mental illness and public health expenditure by considering the impact of cultural access.     

Multidimensional Poverty in Paraguay: Trends from 2000 to 2015

The paper discusses Kenneth C. Land and Alex C. Michalos’ review and assessment of the evolution of research on social indicators, quality of life and well-being over the past fifty years. The contribution deals with the impacts of three major societal changes on the future research agenda of social indicators research: firstly, impacts of the changing class structure of post-industrial society, secondly, globalization impacts, including its economic, political, cultural and institutional dimensions, and thirdly, the impacts of an increasingly networked digitalization of production and consumption.     

Adverse Childhood Experiences and Gambling: Results From a National Survey

Pathological gambling disorder and problem gambling are addictive disorders with severe consequences for individuals, families, and society. Knowledge about associations between childhood adverse experiences (i.e., physical, sexual, and emotional abuse) and gambling pathology in adulthood is limited. Using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), associations between adverse childhood experiences and lifetime gambling status were tested. Strong bivariate associations between adverse childhood experiences and gambling status were found, which were attenuated with the inclusion of clinical covariates. Adverse childhood experiences might be related to pathological gambling in adulthood, but this relationship might not be gambling-specific.
