Job-demand for Learning and Job-related Learning: the Mediating Effect of Job Performance Improvement Initiatives

This study examined whether job-performance-improvementinitiatives mediate the relationship between individuals’ job-demand for learning and job-related learning. Data were obtained from 115 full-time employees in a diverse range of occupations. A partial least squares analysis revealed that job-performance-improvement-initiatives mediate partially the effects of job-demand for learning on job-related learning. Several implications for future research and policy are drawn from the findings.

Outcome of the Public Consultation on the Draft Opinion of the Scientific Panel on Dietetic Products, Nutrition, and Allergies (NDA) on Dietary Reference Values for Fats, Including Saturated Fatty Acids, Polyunsaturated Fatty Acids, Monounsaturated Fatty Acids, Trans Fatty Acids, and Cholesterol

On 2 July 2009, the EFSA Panel on Dietetic products, Nutrition and Allergies (NDA) endorsed a draft Opinion on Dietary Reference Values for fats to be released for public consultation. This Scientific Report summarises the comments received through the public consultation and outlines how these were taken into account in the final opinion. EFSA had received contributions from 40 interested parties (individuals, non-governmental organisations, industry organisations, academia and national assessment bodies). The main comments which were received during the public consultation related to: the availability of more recent data, the nomenclature used, the use of a non-European food composition data base, the impact of genetic factors in modulating the absorption, metabolism and health effects of different fatty acids, the definition of “nutritionally adequate diet”, the use of Dietary Reference Values in the labelling of foods, the translation of advice into food-based dietary guidelines, nutrient goals and recommendations, certain risk management issues, and to Dietary Reference Values of fats, individual fatty acids, and cholesterol. All the public comments received that related to the remit of EFSA were assessed and the Opinion on Dietary Reference Values for fats has been revised taking relevant comments into consideration.

Prevalence of Aspergillus fumigatus complex in waste sorting and incineration plants: an occupational threat

Aspergillus fumigatus is one of the major ubiquitous saprophytic fungi and it is considered one of the fungal species with higher clinical relevance. This study aimed at characterising the prevalence of A. fumigatus complex in one waste-sorting plant and also in one incineration plant. Conventional and molecular methodologies were applied in order to detect its presence. Aspergillus fumigatus complex was the second most frequently found in the air from the waste-sorting plant (16.0%) and from the incineration plant (18.0%). Regarding surfaces, it ranked the third species most frequently found in the waste-sorting plant (13.8%) and the second in the incineration plant (22.3%). In the waste-sorting plant, it was possible to amplify by qPCR DNA from the A. fumigatus complex in all culture-positive sampling sites plus one other sampling site that was negative by culture analysis. Considering the observed fungal load, it is recommended to apply preventive and protective measures in order to avoid or minimise worker's exposure.

Inbound logistics, the last mile and intermodal high capacity transport – the case of Jula in Sweden

Some of the biggest challenges for intermodal transport competitiveness are the extra handling costs and pre- and post-haulage costs. This paper investigates the use of Intermodal High Capacity Transport (IHCT) for the intermodal transport chain in general and to pre-and post-haulage in particular. The aim is not only to measure the cost reductions from using larger vehicles but to understand how better management of inbound flows through increased integration of logistics processes can increase the efficiency of the last mile. The paper analyses the haulage of two 40 foot containers simultaneously when part of an intermodal transport chain. Data were collected from a demonstration project in Sweden, where permission was obtained to use longer vehicles on an approved route to and from the nearest intermodal terminal. Results indicate substantial cost savings from using longer vehicles for pre- and post-haulage. In addition, the business model whereby the shipper purchased their own chassis and permission was obtained to access the terminal after hours for collecting pre-loaded chassis brought additional cost and planning benefits. The total cost saving was significant and potentially eliminates the cost deficit associated with the last mile.

Rule Generalisation in Intrusion Detection Systems using Snort

Intrusion Detection Systems (IDSs) provide an important layer of security for computer systems and networks, and are becoming more and more necessary as reliance on Internet services increases and systems with sensitive data are more commonly open to Internet access. An IDS’s responsibility is to detect suspicious or unacceptable system and network activity and to alert a systems administrator to this activity. The majority of IDSs use a set of signatures that define what suspicious traffic is, and Snort is one popular and actively developing open-source IDS that uses such a set of signatures known as Snort rules. Our aim is to identify a way in which Snort could be developed further by generalising rules to identify novel attacks. In particular, we attempted to relax and vary the conditions and parameters of current Snort rules, using a similar approach to classic rule learning operators such as generalisation and specialisation. We demonstrate the effectiveness of our approach through experiments with standard datasets and show that we are able to detect previously undetected variants of various attacks. We conclude by discussing the general effectiveness and appropriateness of generalisation in Snort based IDS rule processing. Keywords: anomaly detection, intrusion detection, Snort, Snort rules

Government management of tourism in fostering residents support for sustainable tourism development: Evidence from a Portuguese historic town

This study proposes a conceptual framework that explores the correlations between economic dependence (ED), local government management of tourism (GMT), perceived tourism benefits and costs, and support for sustainable tourism development (STD). A quantitative research design was adopted. Data collection was carried out by personal survey applied to 300 residents of the small historic town of Lamego, located within the Douro Valley World Heritage Site. Structural equation modelling methods were employed to analyse the proposed model. Results suggest that GMT has a significant effect on the perceived impacts of tourism, both in the positive and in the negative. The effect of GMT in fostering residents’ support to STD was also empirically supported. Additionally, it was also determined that positive perceptions of the impacts of tourism directly influence support to STD. Nevertheless, ED does not have a significant effect either on perceivedbenefits, nor on perceived costs or on residents’ support to STD. Likewise, perceptions of the negative impacts do not predict residents’ support to STD.

História da missão dos padres capuchinhos na ilha do Maranhão e suas circumvisinhaças

O autor passou quatro meses no Maranhão e em 1614 editou a obra em francês. A presente tradução brasileira, ainda que seja a primeira, é considerada imperfeita, na visão de Rubens Borba de Moraes. O texto, porém, é considerado um clássico da etnografia brasileira e uma importante contribuição acerca do domínio francês no Maranhão.

La Banda de Alabarderos (1746-1939). Música y músicos en la jefatura del estado

La Banda de Alabarderos tiene su origen en 1746 dentro del cuerpo homónimo que fue creado por el cronista Gonzalo de Ayora en 1504 para la seguridad del católico rey Fernando. Con el transcurso del tiempo la agrupación musical presenta varios cambios de denominación, así pues, a mediados del XVIII se convierte en la Banda de música del Cuerpo de Guardias de la Reina. Algunos años después se reinstaura nuevamente el cuerpo de Alabarderos hasta llegar a 1868 en el que es disuelto durante el inicio del Sexenio Revolucionario y con él, su banda de música. Con la Restauración Alfonsina en 1875 se reconstruye la Banda de Alabarderos con muchos de los profesores que tenía anteriormente, hasta llegar al siguiente cambio de régimen político durante la primavera de 1931, en el que, tras unos días de incertidumbre por su desintegración como agrupación musical, se decide su continuidad con la nueva denominación de Banda Republicana. Tras la finalización de la Guerra Civil, resurge compuesta por nuevo profesorado, con el nombre de Banda de música del Regimiento del Jefe del Estado y Generalísimo de los Ejércitos, la cual, hereda de la anterior Banda Republicana, su archivo musical, parte de su instrumental y la mayoría de las funciones oficiales. Con el inicio del periodo democrático a partir de 1975, esta misma formación musical, con los mismos músicos y la misma plantilla instrumental, pasa a formar parte de la nueva Guardia Real, llegando hasta la actualidad con la nueva designación de Unidad de Música de la Guardia Real. Podemos afirmar que las bandas de Alabarderos, del Cuerpo de Guardias de la Reina, Nacional Republicana, del Regimiento de la Jefatura del Estado o de la Guardia Real, son una única banda de música con diferentes denominaciones, siempre ligada a la Jefatura del Estado, que desde su creación y a excepción del Sexenio Revolucionario, ha perdurado en el tiempo hasta la actualidad...

Modelling and simulating retail management practices: a first approach

Multi-agent systems offer a new and exciting way of understanding the world of work. We apply agent-based modeling and simulation to investigate a set of problems in a retail context. Specifically, we are working to understand the relationship between people management practices on the shop-floor and retail performance. Despite the fact we are working within a relatively novel and complex domain, it is clear that using an agent-based approach offers great potential for improving organizational capabilities in the future. Our multi-disciplinary research team has worked closely with one of the UK’s top ten retailers to collect data and build an understanding of shop-floor operations and the key actors in a department (customers, staff, and managers). Based on this case study we have built and tested our first version of a retail branch agent-based simulation model where we have focused on how we can simulate the effects of people management practices on customer satisfaction and sales. In our experiments we have looked at employee development and cashier empowerment as two examples of shop floor management practices. In this paper we describe the underlying conceptual ideas and the features of our simulation model. We present a selection of experiments we have conducted in order to validate our simulation model and to show its potential for answering “what-if” questions in a retail context. We also introduce a novel performance measure which we have created to quantify customers’ satisfaction with service, based on their individual shopping experiences.

Aproximación al desarrollo de un sistema de transporte masivo a través de la dinámica de sistemas

El porvenir social y económico de una ciudad depende, en gran medida, de la eficiencia de su sistema de transporte; esto se ve reflejado en la capacidad de transportar personas y bienes de una forma sostenible, con los recursos disponibles. En la actualidad se encuentran en desarrollo sistemas de transporte masivo tipo Bus Rapid Transit [BRT] en siete ciudades colombianas, situación que genera la necesidad de dar seguimiento a su progreso y al crecimiento de su participación en la demanda de viajes unipersonales. El siguiente trabajo busca, a través de una simulación en dinámica de sistemas, describir el desarrollo de un sistema de transporte masivo, con el fin de otorgar una visión acerca del impacto de los parámetros operativos y la reinversión en el sistema y en el desarrollo e incremento de su demanda. Se plantean tres escenarios para evaluar diferentes políticas operativas y de reinversión en el sistema, analizando el comportamiento en su desarrollo.

American Perceptions of British Regional Dialects

Sociolinguists have discussed problematic language ideologies, such as Standard Language Ideology (Lippi-Green 1997) extensively and social perceptions of Standard English in the U.S and U.K are well documented. However, most work in this area has focused on perceptions of dialects within national contexts. This study makes a novel contribution to the study of language attitudes, investigating perceptions of British regional dialects within the U.S. A survey was created to gauge perceptions of five British regional dialects (Liverpool, Leeds, Birmingham, Newcastle, London). 49 survey participants listened to audio clips of British regional dialect speakers and then completed a mapping activity, answered perception questions, and ranked each speaker on specific qualities. Results showed that speaker region had a significant effect on perception of almost all variables at a statistically significant rate, despite unfamiliarity with all but the London dialect. Results suggest that although participants are largely unfamiliar with varieties of English in England outside of London, they assessed them by recruiting pre-existing stereotypes about vernacular dialects.

Website content and design in SME: insights from Portugal

Although there is a vast amount of literature on website evaluation, relatively little has been written about the analysis of websites of small and medium-sized enterprises (SME). This paper examines a comprehensive set of content and design features of 915 websites of Portuguese SME, as well as the relationship between these features and enterprise size. The results indicate that the majority of the websites are used to convey information, rather than to make transactions, support networking and collaboration or to interact dynamically with users. Accessibility or privacy and security features are not common among websites. Web 2.0 features have a low presence in SME websites, but social media emerged as a construct. In contrast with existing literature, the study has found that website content and design features are positively related with enterprise size. The contributions and implications are discussed together with avenues for further research.
