Understanding the value of reputation systems in enterprise social media (ESM)-mutual influence between online and offline performance

One major concern that organizations face when deploying Enterprise Social Media (ESM) platforms is that of how to encourage employees' engagement within the system. Reputation systems that gamify the adoption process are incorporated into many ESM to inculcate employee engagement with the ESM. This study seeks to understand the dynamic between employees' online and offline performance by examinin

Influence of Injection Timing on Exhaust Particulate Matter Emissions of Gasoline in HCCI and PPC

In order to reduce nitrogen oxides (NOx) and soot emissions while maintaining high thermal efficiency, more advanced combustion concepts have been developed over the years, such as Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), as possible combustion processes in commercial engines. Compared to HCCI, PPC has advantages of lower unburned hydrocarbon (UHC) an

Separating effects of species identity and species richness on predation, pathogen dissemination and resistance to invasive species in tropical ant communities

Ants are abundant in natural and managed tropical ecosystems and can have an impact on herbivorous arthropods, as well as plant pathogens. Although it has been shown for plants that the diversity of communities can result in improved ecosystem functioning, it remains uncertain how the species richness of ants affects multiple ecosystem services and disservices. In the present study, we used experi

Nanoscale analysis of the oxidation state and surface termination of praseodymium oxide ultrathin films on ruthenium(0001)

The complex structure and morphology of ultrathin praseodymia films deposited on a ruthenium(0001) single crystal substrate by reactive molecular beam epitaxy is analyzed by intensity-voltage low-energy electron microscopy in combination with theoretical calculations within an ab initio scattering theory. A rich coexistence of various nanoscale crystalline surface structures is identified for the

Legal Power: The Basic Definition

The concept of legal power (often called legal competence) is important inthe law since, with regard to actions having legal effect, the “exercise of legal power” delimits those actions for which manifestation of intention to achieve a legal effect is essential for the effect to ensue. The paper proposes a definition that captures this feature of legal power and marks it off from “direct effect,” The concept of legal power (often called legal competence) is important in the law since, with regard to actions having legal effect, the “exercise of legal power” delimits those actions for which manifestation of intention to achieve a legal effect is essential for the effect to ensue.

Modelling of the integration tasks of product and packaging development

PurposeThere is a growing demand for a concurrent development of product and packaging in order to better take into account the supply chain needs. Different tasks are required to integrate packaging and product development: 1) At the strategic level, it is necessary to define or refine an integrated development policy; 2) For each new development project, an adaptation of this policy must be unde

Sleep and circadian rhythm regulation in early Parkinson disease

IMPORTANCE: Sleep disturbances are recognized as a common nonmotor complaint in Parkinson disease but their etiology is poorly understood.OBJECTIVE: To define the sleep and circadian phenotype of patients with early-stage Parkinson disease.DESIGN, SETTING, AND PARTICIPANTS: Initial assessment of sleep characteristics in a large population-representative incident Parkinson disease cohort (N=239) at

The spectrum of cognitive impairment in Lewy body diseases

Cognitive impairment represents an important and often defining component of the clinical syndromes of Lewy body disorders: Parkinson's disease and dementia with Lewy bodies. The spectrum of cognitive deficits in these Lewy body diseases encompasses a broad range of clinical features, severity of impairment, and timing of presentation. It is now recognized that cognitive dysfunction occurs not onl

Improving response inhibition in Parkinson's disease with atomoxetine

BACKGROUND: Dopaminergic drugs remain the mainstay of Parkinson's disease therapy but often fail to improve cognitive problems such as impulsivity. This may be due to the loss of other neurotransmitters, including noradrenaline, which is linked to impulsivity and response inhibition. We therefore examined the effect of the selective noradrenaline reuptake inhibitor atomoxetine on response inhibiti

Health-related quality of life in early Parkinson's disease : the impact of nonmotor symptoms

Nonmotor symptoms (NMS) are common in patients with established Parkinson's disease (PD) and have a major impact upon quality of life. We investigated the significance of NMS in relation to health-related quality of life (HRQoL) in patients with newly diagnosed PD. Patients and healthy controls were recruited as part of the Incidence of Cognitive Impairment in Cohorts with Longitudinal Evaluation

Global trends of pCO2 across the Cretaceous–Paleogene boundary supported by the first Southern Hemisphere stomatal proxy-based pCO2 reconstruction

Reliable reconstructions of atmospheric carbon dioxide concentrations (pCO2) are required at higher resolution than currently available to help resolve the relationship between mass extinctions and changes in palaeo-pCO2 levels. Such reconstructions are needed: 1, at a high temporal resolution for constraining the pre- and post-extinction atmospheres; and 2, at a sufficient spatial resolution to c
