However, there had been no way to assess the problem. This study aimed to develop a scale for physicians to measure difficulties in nighttime collaboration with nurses in response to deteriorating inpatients and to identify factors associated with the developed scale scores.Methods: We developed a draft scale of Nighttime Collaboration Difficulties between Nurses and Physicians for Physicians (NCDNP-P) based on key informant interviews with physicians. Psychometric validations, including structural validity, criterion-related validity, and reliability tests, were conducted among physicians who worked on night duty or on call in acute-care hospitals in Japan using a cross-sectional web-based questionnaire. Multiple linear regression analyses were performed using independent variables including individual backgrounds, style of working at night, and facility characteristics.Results: By performing exploratory factor analysis, we confirmed the structural validity of the NCDNP-P, consisting of seven items and two domains (Domain 1: Dissatisfaction with reporting, Domain 2: Barriers to working with nurses). Cronbach’s alpha and McDonald’s omega coefficients were 0.81– 0.84 and 0.81– 0.89, respectively. The criterion-related validity for interprofessional collaboration was confirmed. Multiple regression analysis revealed that the variables employment status, number of night shifts, frequency of nighttime calls about patients under another physician’s charge, and handover between physicians before changing shifts were statistically significantly associated with NCDNP-P scores.Conclusion: We developed the NCDNP-P, confirming its reliability and validity. Identified factors reflect physicians’ characteristics and the problems experienced working at night and may be associated with barriers in nighttime collaboration. The NCDNP-P can highlight issues in clinical settings and lead to the consideration of initiatives to address such issues.Keywords: clinical deterioration, interprofessional collaboration, scale development, nighttime

In this paper we analyse the infrared and Raman spectra of two thiophene-based oligomers functionalized with aminomethyl groups in the α,α´-positions, in both neutral and oxidized states. These results will be extrapoled when these systems are assembled in Langmuir-Blodgett or CVD thin films.En este artículo analizamos los espectros Raman de dos oligómeros de tiofeno funcionalizados selectivamente con grupos aminometilos en sus posiciones α,α´ tanto en estado neutro como oxidado. Los resultados obtenidos pueden ser utilizados para analizar las propiedades electrónicas de dichos compuestos cuando se disponen en láminas delgadas de tipo Langmuir- Blodgett o CVD.

Issues concerning the vibrational properties of a series of pi-conjugated alpha,alpha'-bis(aminomethyl) oligothiophenes as solids are discussed. It has been established that an effective electron-phonon interaction arises in these systems.

A study was conducted to analyze the vibrational Fourier transform infrared and Fourier transform-raman spectra of a series of alpha,alpha'-diethyl substituted oligothiophenes with variable chain lengths in the neutral state. Ab initio quadratic force field computations were carried out for each oligomer using the Gaussian 94 program. Geometry optimizations were then performed on isolated entities.

The degree of π conjugation in a novel series of molecular materials containing a central oligothiophene moiety of variable length, with its end α positions capped by phenyl groups (PnTP; n = 1-4) is closely inspected by means of Fourier-transform infrared and Fourier-transform Raman spectroscopies in the neutral state as solids. Density functional theory quantum chemical calculations were performed for each co-oligomer, at the B3LYP/6-31G[sup **] level, to obtain the optimized molecular geometry and force field. The thermal stability of these oligothiophenes has been also investigated, at the molecular level, by recording infrared and Raman spectra at different temperatures between - 170 °C and 160°C.
