Effects of internal brand knowledge dissemination on the employee

Purpose: This study aims to examine the internal brand knowledge dissemination process in the banking sector and its effects on employees. Specifically, it focuses on the key roles of employee identification with both the organization and with the customer as antecedents of behaviors supportive of the brand, i.e. employee citizenship behaviors and recommendation behaviors. Design/methodology/approach: An empirical study was carried out in a major Spanish bank. Data gathered from a survey of 315 employees were analyzed through structural equation modeling. Findings: The results showed that employees'' perceptions of brand value congruence are key in explaining their identification with both the organization and with the customer. However, the employees'' perceptions of the brand''s authenticity explained only their recommendations of the bank as a good place to work. Originality/value: These findings contribute to the advance in the current knowledge of the role of variables such as brand authenticity and employee–customer identification in internal brand management. From a managerial viewpoint, the results provide insights into the importance of employees'' perceptions and attitudes when it comes to brand knowledge dissemination. © 2021, Emerald Publishing Limited

GRB000301C with peculiar afterglow emission

The CCD magnitudes in Johnson V and Cousins R and I photometric passbands are determined for GRB 000301C afterglow starting ~ 1.5 day after the gamma-ray burst. In fact we provide the earliest optical observations for this burst. Light curves of the afterglow emissions in U, B, V, R, I, J and K' passbands are obtained by combining the present measurements with the published data. Flux decay shows a very uncommon variation relative to other well observed GRBs. Overall, there is a steepening of the optical and near-infrared flux decay caused by a geometric and sideways expanding jet. This is superimposed by a short term variability especially during early time (Delta t < 8 days). The cause of variability is not well understood, though it has occurred simultaneously with similar amplitude in all the filters. We derive the early and late time flux decay constants using jet model. The late time flux decay is the steepest amongst the GRB OTs observed so far with alpha ~ 3. Steepening in the flux decay seems to have started simultaneously around Delta t ~ 7.6 day in all passbands. The value of spectral index in the optical-near IR region is ~ -1.0. Redshift determination with z=2.0335 indicates cosmological origin of the GRB having a luminosity distance of 16.6 Gpc. Thus it becomes the second farthest amongst the GRBs with known distances. An indirect estimate of the fluence > 20 keV indicates, if isotropic,> =10^53 ergs of release of energy. The enormous amount of released energy will be reduced, if the radiation is beamed which is the case for this event. Using a jet break time of 7.6 days, we infer a jet opening angle of ~ 0.15 radian. This means the energy released is reduced by a factor of ~ 90 relative to the isotropic value.Comment: LaTeX file, 11 pages including 4 figures, uses psfig.sty, Bull. Astron.

Gait analysis for challenged users based on a rollator equipped with force sensors

El análisis del paso proporciona información detallada acerca del estado de los pacientes, su progreso en los tratamientos de rehabilitación y el riesgo de caídas que tienen. Este análisis se realiza usualmente en condiciones muy específicas, haciendo uso de cintas de andar, cámaras y/o sensores vestibles. En el artículo presentado en esta conferencia, se propone un análisis del paso usando un andador inteligente, equipado con un conjunto básico de sensores. Este trabajo propone una metodología para obtener los parámetros relevantes del paso utilizando una herramienta común y de bajo coste: odometría de las ruedas de un andador y sensores de fuerza del manillar. Las principales ventajas de este enfoque es que los usuarios no son molestados con sensores adicionales en su cuerpo. Además, el seguimiento se puede realizar en cualquier lugar, incluso haciendo las actividades de la vida cotidiana y por períodos de tiempo prolongados. Hemos probado nuestro sistema con un conjunto de pacientes de rehabilitación con diferentes discapacidades. Los resultados preliminares han demostrado con éxito que los parámetros extraídos son coherentes con los efectos reportados por el equipo médico sobre su condición.Universidad de Málaga.

Optical afterglow of the not so dark GRB 021211

We determine Johnson $B,V$ and Cousins $R,I$ photometric CCD magnitudes for the afterglow of GRB 021211 during the first night after the GRB trigger. The afterglow was very faint and would have been probably missed if no prompt observation had been conducted. A fraction of the so-called ``dark'' GRBs may thus be just ``optically dim'' and require very deep imaging to be detected. The early-time optical light curve reported by other observers shows prompt emission with properties similar to that of GRB 990123. Following this, the afterglow emission from $\sim 11$ min to $\sim 33$ days after the burst is characterized by an overall power-law decay with a slope $1.1\pm0.02$ in the $R$ passband. We derive the value of spectral index in the optical to near-IR region to be 0.6$\pm$0.2 during 0.13 to 0.8 day after the burst. The flux decay constant and the spectral slope indicate that optical observations within a day after the burst lies between cooling frequency and synchrotron maximum frequency.Comment: 4 pages, 2 figures, A&A Letters, 408, L2

Optical observations of the bright long duration peculiar GRB 021004 afterglow

The CCD magnitudes in Johnson $B,V$ and Cousins $R$ and $I$ photometric passbands are determined for the bright long duration GRB 021004 afterglow from 2002 October 4 to 16 starting $\sim$ 3 hours after the $\gamma-$ray burst. Light curves of the afterglow emission in $B$,$V$,$R$ and $I$ passbands are obtained by combining these measurements with other published data. The earliest optical emission appears to originate in a revese shock. Flux decay of the afterglow shows a very uncommon variation relative to other well-observed GRBs. Rapid light variations, especially during early times ($\Delta t < 2$ days) is superposed on an underlying broken power law decay typical of a jetted afterglow. The flux decay constants at early and late times derived from least square fits to the light curve are $0.99\pm0.05$ and $2.0\pm0.2$ respectively, with a jet break at around 7 day. Comparison with a standard fireball model indicates a total extinction of $E(B-V)=0.20$ mag in the direction of the burst. Our low-resolution spectra corrected for this extinction provide a spectral slope $\beta = 0.6\pm0.02$. This value and the flux decay constants agree well with the electron energy index $p\sim 2.27$ used in the model. The derived jet opening angle of about $7^{\circ}$ implies a total emitted gamma-ray energy $E_{\gamma} = 3.5\times10^{50}$ erg at a cosmological distance of about 20 Gpc. Multiwavelength observations indicate association of this GRB with a star forming region, supporting the case for collapsar origin of long duration GRBs.Comment: 19 pages, 3 figures, BASI, 31, 1
