Band structure engineering of carbon nitride hybrid photocatalysts for CO2 reduction in aqueous solutions

Through the co-polymerisation of dicyandiamide and barbituric acid precursors, a series of visible light active carbon nitride photocatalysts has been prepared and characterized, and their photocatalytic activity has been evaluated. Structural and electronic characterisation has enabled variations in observed activity towards water splitting and CO2 reduction to be understood, both in the presence and absence of the iron porphyrin co-catalyst Feiii tetra(4-carboxylphenyl)porphyrin (FeTCPP). A combination of the most active carbon nitride catalyst using 5 wt% barbituric acid and FeTCPP provides a hybrid system where the alignment of band structure with appropriate reduction potentials and enhanced carrier lifetimes is capable of CO2 reduction in an aqueous solution with >60% selectivity for CO production. This study is one of only a few that achieves selective CO2 reduction using a hybrid molecular catalyst-carbon nitride photocatalyst in aqueous solution

Geriatric rehabilitation of stroke patients in nursing homes: a study protocol.

Contains fulltext : 88482.pdf (publisher's version ) (Open Access)BACKGROUND: Geriatric patients are typically underrepresented in studies on the functional outcome of rehabilitation after stroke. Moreover, most geriatric stroke patients do probably not participate in intensive rehabilitation programs as offered by rehabilitation centers. As a result, very few studies have described the successfulness of geriatric stroke rehabilitation in nursing home patients, although it appears that the majority of these patients are being discharged back to the community, rather than being transferred to residential care. Nevertheless, factors associated with the successfulness of stroke rehabilitation in nursing homes or skilled nursing facilities are largely unknown. The primary goal of this study is, therefore, to assess the factors that uniquely contribute to the successfulness of rehabilitation in geriatric stroke patients that undergo rehabilitation in nursing homes. A secondary goal is to investigate whether these factors are similar to those associated with the outcome of stroke rehabilitation in the literature. METHODS/DESIGN: This study is part of the Geriatric Rehabilitation in AMPutation and Stroke (GRAMPS) study in the Netherlands. It is a longitudinal, observational, multicenter study in 15 nursing homes in the Southern part of the Netherlands that aims to include at least 200 patients. All participating nursing homes are selected based on the existence of a specialized rehabilitation unit and the provision of dedicated multidisciplinary care. Patient characteristics, disease characteristics, functional status, cognition, behavior, and caregiver information, are collected within two weeks after admission to the nursing home. The first follow-up is at discharge from the nursing home or one year after inclusion, and focuses on functional status and behavior. Successful rehabilitation is defined as discharge from the nursing home to an independent living situation within one year after admission. The second follow-up is three months after discharge in patients who rehabilitated successfully, and assesses functional status, behavior, and quality of life. All instruments used in this study have shown to be valid and reliable in rehabilitation research or are recommended by the Netherlands Heart Foundation guidelines for stroke rehabilitation.Data will be analyzed using SPSS 16.0. Besides descriptive analyses, both univariate and multivariate analyses will be performed with the purpose of identifying associated factors as well as their unique contribution to determining successful rehabilitation. DISCUSSION: This study will provide more information about geriatric stroke rehabilitation in Dutch nursing homes. To our knowledge, this is the first large study that focuses on the determinants of success of geriatric stroke rehabilitation in nursing home patients

It's a Matter of Congruence: How Interpersonal Identification between Sales Managers and Salespersons Shapes Sales Success

In recent years, marketing research and practice have recognized the importance of managing frontline employees' identification. However, investigations so far have focused on identification at the collective level of the self, such as organizational identification, thereby largely neglecting important interpersonal identification processes at the relational level. Using a large-scale data set comprising information from sales managers and salespeople as well as company data on customer satisfaction and sales performance, the authors make a first attempt to address this neglect by exploring important phenomena of interpersonal identification in the sales manager-salesperson dyad. Results show that initial increases in the level of identification congruence between sales managers and their respective salespeople yield positive incremental effects on sales performance and customer satisfaction. Findings also show that interpersonal over-identification and identification incongruence are negatively related to both outcomes. Results demonstrate how sales managers could mitigate these negative effects
