This study reviewed the ergonomics process at a large automotive manufacturing company. Since program inception in 1989, the Company and the UAW have been industry leaders in developing a participatory ergonomics program at the plant level. Every large US facility has a locally controlled and operated cross-functional ergonomics team. in the years following implementation (1997–2001), extensive program development and team training have been well established. During program maturation, the organization as a whole has seen significant reductions in lost time case rate for cases of ergonomic interest (14.6%/year) and has had a strong decreasing trend for severity rate for cases of ergonomic interest (39.5 days/year). The local level teams are evaluated on their adherence to the ergonomic program with the use of process metrics including internal audits, OSHA compliance, and intervention activity level. The jointly designed process was developed with the intent of reducing injury rates (outcome metrics). This paper will evaluate the correlation between the ergonomics program outcome metrics and the process metrics.

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper OTC 30794, “Digitalization Deployed: Lessons Learned From Early Adopters,” by John Nixon, Siemens, prepared for the 2020 Offshore Technology Conference, originally scheduled to be held in Houston, 4–7 May. The paper has not been peer reviewed. Copyright 2020 Offshore Technology Conference. Reproduced by permission. With full-scale digital transformation of oil and gas an inevitability, the industry can benefit by examining the strategies of industries such as automotive, manufacturing, marine, and aerospace that have been early adopters. This paper discusses how digital technologies are being applied in other verticals and how they can be leveraged to optimize life-cycle performance, drive down costs, and decouple market volatility from profitability for offshore oil and gas facilities. Barriers to Digital Adoption Despite the recent dramatic growth in use of digital tools to harness the power of data, the industry as a whole has remained conservative in its pace of digital adoption. Most organizations continue to leverage technology in disaggregated fashion. This has resulted in an operating environment in which companies can capture incremental inefficiencies and cost savings on a local level but have been largely unable to cause any discernible effect on operating or business models. Although the recent market downturn constrained capital budgets significantly, an ingrained risk-averse culture is also to blame. Other often-cited reasons for the industry’s reluctance to digitally transform include cost of downtime, cyber-security and data privacy, and limited human capital. A single offshore oil and gas facility failure or plant trip can result in millions of dollars in production losses. Therefore, any solution that has the potential to affect a process or its safety negatively must be proved before being implemented. Throughout its history, the industry has taken a conservative approach when adopting new technologies, even those designed to prevent unplanned downtime. Although many current technologies promise increases of 1 to 2% in production efficiency, these gains become insignificant in the offshore industry if risk exists that deployment of the technology could in any way disrupt operations. Cybersecurity and data privacy are perhaps the most-significant concerns related to adoption of digital solutions by the industry, and they are well-founded. Much of today’s offshore infrastructure was not designed with connectivity or the Internet of Things in mind. Digital capabilities have simply been bolted on. In a recent survey of oil and gas executives, more than 60% of respondents said their organization’s industrial control systems’ protection and security were inadequate, and over two-thirds said they had experienced at least one cybersecurity attack in the previous year. Given this reality, it is no surprise that offshore operators have been reluctant to connect their critical assets. They are also cautious about sharing performance data with vendors and suppliers. This lack of collaboration and connectivity has inevitably slowed the pace of digital transformation, the extent to which it can be leveraged, and the value it can generate.

ObjectiveTo evaluate long-term associations between early childhood hyperactivity and conduct problems (CP), measured using Strengths and Difficulties Questionnaire (SDQ) and risk of injury in early adolescence.DesignData linkage between a longitudinal birth cohort and routinely collected electronic health records.SettingConsenting Millennium Cohort Study (MCS) participants residing in Wales and Scotland.Patients3119 children who participated in the age 5 MCS interview.Main outcome measuresChildren with parent-reported SDQ scores were linked with hospital admission and Accident & Emergency (A&E) department records for injuries between ages 9 and 14 years. Negative binomial regression models adjusting for number of people in the household, lone parent, residential area, household poverty, maternal age and academic qualification, child sex, physical activity level and country of interview were fitted in the models.Results46% of children attended A&E or were admitted to hospital for injury, and 11% had high/abnormal scores for hyperactivity and CP. High/abnormal or borderline hyperactivity were not significantly associated with risk of injury, incidence rate ratio (IRR) with 95% CI of the high/abnormal and borderline were 0.92 (95% CI 0.74 to 1.14) and 1.16 (95% CI 0.88 to 1.52), respectively. Children with borderline CP had higher injury rates compared with those without CP (IRR 1.31, 95% CI 1.09 to 1.57).ConclusionsChildren with high/abnormal hyperactivity or CP scores were not at increased risk of injury; however, those with borderline CP had higher injury rates. Further research is needed to understand if those with difficulties receive treatment and support, which may reduce the likelihood of injuries.

This study examines the impact of OSHA inspections on injuries in manufacturing plants. The authors use the same model and some of the same plant-level data employed by several earlier studies that found large effects of OSHA inspections on injuries for 1979–85. These new estimates indicate that an OSHA inspection imposing a penalty reduced lost-workday injuries by about 19% in 1979–85, but that this effect fell to 11% in 1987–91, and to a statistically insignificant 1% in 1992–98. The authors cannot fully explain this overall decline, which they find for nearly all subgroups they examine—by inspection type, establishment size, and industry, for example. Among other findings are that, across the years studied, inspections with penalties were more effective than those without, and the effects on injury rates were greater in smaller plants and nonunion plants than in large plants and union plants.

Abstract The current COVID-19 pandemic has sparked growing global interest in understanding the spread and outcome of the virus. From previous pandemics, we have learned that several demographic, geographic, and socio-economic factors may play a role in increasing risk of infection. Our objective was to examine the association of timing of mandated stay-at-home orders at the county-level with COVID-19 cases, daily case rate and mortality in the United States of America (USA). Publicly available data were used to perform a cross-sectional study of USA counties with > 100,000 population, and at least 50 confirmed cases per 100,000 people as of May 24, 2020. The three outcome variables were: total cases/100,000, daily case rate (DCR), and total deaths/100,000. Out of 3142 USA counties, 569 met the inclusion criteria. Of all variables, the timing of state-mandated stay-at-home order had the most significant effect on all three outcomes after adjusting for multiple socio-demographic, geographic and health related factors. Additional factors with significant association with increased cases and deaths include population density, housing problem, unemployment, African American race, and age > 65. Policymakers at the local level must take this into consideration while planning for interventions to prevent the spread of COVID-19.

Abstract Kinetochores are instrumental for accurate chromosome segregation by binding to microtubules in order to move chromosomes and by delaying anaphase onset through the spindle assembly checkpoint (SAC). Dynamic phosphorylation of kinetochore components is key to control these activities and is tightly regulated by temporal and spatial recruitment of kinases and phosphoprotein phosphatases (PPPs). Here we focus on PP1, PP2A-B56 and PP2A-B55, three PPPs that are important regulators of mitosis. Despite the fact that these PPPs share a very similar active site, they target unique ser/thr phosphorylation sites to control kinetochore function. Specificity is in part achieved by PPPs binding to short linear motifs (SLiMs) that guide their substrate specificity. SLiMs bind to conserved pockets on PPPs and are degenerate in nature, giving rise to a range of binding affinities. These SLiMs control the assembly of numerous substrate specifying complexes and their position and binding strength allow PPPs to target specific phosphorylation sites. In addition, the activity of PPPs is regulated by mitotic kinases and inhibitors, either directly at the activity level or through affecting PPP–SLiM interactions. Here, we discuss recent progress in understanding the regulation of PPP specificity and activity and how this controls kinetochore biology.

Adherence to lifestyle changes - beginning to exercise, for example - is assumed to be mediated by self-referent thoughts. This paper describes a pilot study and three studies conducted to develop and validate a questionnaire for adults to determine their self-perceptions related to health-oriented exercise. The pilot study identified items pertinent to the domains considered important in this context, and began the process of selecting items. Study 2 examined the factor structure, reduced the number of items, determined the internal consistency of the factors, and explored the discriminative validity of the questionnaire as to physical activity level and gender. Four factors with a total of 24 items were accepted, measuring mastery of exercise, body perception, social comfort/discomfort in the exercise setting, and perception of fitness. All subscales had acceptable internal consistencies. Preliminary validity was demonstrated by confirming hypothesized differences in scores as to gender, age, and physical activity level. The third study examined and demonstrated convergent validity with similar existing subscales. The fourth study examined an English-language version of the questionnaire, confirming the existence of the factors and providing preliminary psychometric evidence of the viability of the questionnaire.

The visual environment consists of global structures (e.g., a forest) made up of local parts (e.g., trees). When compound stimuli are presented (e.g., large global letters composed of arrangements of small local letters), the global unattended information slows responses to local targets. Using a negative priming paradigm, we investigated whether inhibition is required to process hierarchical stimuli when information at the local level is in conflict with the one at the global level. The results show that when local and global information is in conflict, global information must be inhibited to process local information, but that the reverse is not true. This finding has potential direct implications for brain models of visual recognition, by suggesting that when local information is conflicting with global information, inhibitory control reduces feedback activity from global information (e.g., inhibits the forest) which allows the visual system to process local information (e.g., to focus attention on a particular tree).
