The impact of ICT (information and communications technology) on the logistics service industry is reshaping its organisation and structure. Within this process, the nature of changes resulting from ICT dissemination in small 3PLs (third party logistics providers) is still unclear, although a large number of logistics service markets, especially in the EU context, are populated by a high number of small 3PLs. In addition, there is still a gap in the literature where the role of technological capability in small 3PLs is seriously underestimated. This gives rise to the need to develop investigation in this area. The paper presents the preliminary results of a case study analysis on ICT usage in a sample of 7 small Italian 3PLs. The results highlight some of the barriers to effective ICT implementation, as well as some of the critical success factors.

Tudomány nem létezik a tények felmérése, adatok gyűjtése és felhasználása nélkül. A tényeket azonban el lehet hallgatni vagy ferdíteni, az adatokat sokféleképpen lehet összeválogatni, az azokból készült mutatószámokat pedig a bonyolult és változó valóság leegyszerűsítő, sőt meghamisító ábrázolására, illetve magyarázatára is fel lehet használni. _____ Economics cannot do without measuring. However, the required data are not always available or they are not reliable, as some cases of population census exemplify it. The indicators we use, particularly composite indexes, are often misleading because they oversimplify complex phenomena or processes, and neglect important non-measurable ones, as the examples of the per capita GDP indicator measuring the development level of countries, and the composite indexes measuring the “human development” of countries (HDI), or their “national competitiveness” (GCI) may show. To avoid the enchantment of numbers, the quantitative approach must always be combined and corrected by a critical, holistic and qualitative approach.

A szerzők ebben a tanulmányukban az információs és kommunikációs technológiai (továbbiakban IKT) eszközök közül az asztali számítógépekkel (desktopok), laptopokkal (notebookok és netbookok), táblagépekkel és okostelefonokkal foglalkoznak. Az IKT-eszközök elterjedtségének vizsgálatánál meghatározó szerepet játszik a technológia jelenléte mellett a társadalom befogadóképessége. A technológia és társadalom kapcsolatát különböző módszerekkel és modellekkel mutatják be, melyek indokolják ezen eszközök növekvő használatának szükségességét. Ebben a tanulmányban a modellekből és a felmérésekből összeállított tényezők beépítésével és az általuk feldolgozott kérdőívek elemzése által kirajzolódnak minták és olyan összefüggések, amelyek magyarázatot adhatnak a különböző eszközhasználat okainak megértésére. _____ In their study the authors deal with the desktop computers (Desktop), laptops (notebooks and netbooks), smartphones and tablet machines among of information and communication technology (hereinafter referred to as ICT) tools. The capacity of society is one of the key elements in the examination of spread of ICT. The relationship between technology and society is presented with different methods and models that are justified by the need for increasing the use of these devices. In this paper such samples and correlations are emerged of the models and surveys, which may explain the reasons for understanding of the different tool use.

Computers have dramatically changed the way we live, conduct business, and deliver education. They have infiltrated the Bahamian public school system to the extent that many educators now feel the need for a national plan. The development of such a plan is a challenging undertaking, especially in developing countries where physical, financial, and human resources are scarce. This study assessed the situation with regard to computers within the Bahamian public school system, and provided recommended guidelines to the Bahamian government based on the results of a survey, the body of knowledge about trends in computer usage in schools, and the country's needs. ^ This was a descriptive study for which an extensive review of literature in areas of computer hardware, software, teacher training, research, curriculum, support services and local context variables was undertaken. One objective of the study was to establish what should or could be relative to the state-of-the-art in educational computing. A survey was conducted involving 201 teachers and 51 school administrators from 60 randomly selected Bahamian public schools. A random stratified cluster sampling technique was used. ^ This study used both quantitative and qualitative research methodologies. Quantitative methods were used to summarize the data about numbers and types of computers, categories of software available, peripheral equipment, and related topics through the use of forced-choice questions in a survey instrument. Results of these were displayed in tables and charts. Qualitative methods, data synthesis and content analysis, were used to analyze the non-numeric data obtained from open-ended questions on teachers' and school administrators' questionnaires, such as those regarding teachers' perceptions and attitudes about computers and their use in classrooms. Also, interpretative methodologies were used to analyze the qualitative results of several interviews conducted with senior public school system's officials. Content analysis was used to gather data from the literature on topics pertaining to the study. ^ Based on the literature review and the data gathered for this study a number of recommendations are presented. These recommendations may be used by the government of the Commonwealth of The Bahamas to establish policies with regard to the use of computers within the public school system. ^

BACKGROUND AND OBJECTIVES: Analysis of IgH rearrangements in B-cell malignancies has provided clinical researchers with a wide range of information during the last few years. However, only a few studies have contributed to the characterization of these features in multiple myeloma (MM), and they have been focused on the analysis of the expressed IgH allele only. Comparison between the expressed and the non-functional IgH alleles allows further characterizion of the selection processes to which pre-myeloma cells are submitted. DESIGN AND METHODS: We analyzed a cohort of 84 untreated MM patients in order to characterize their functional VDJH and non-functional DJH rearrangements. The pattern of mutations and gene segment usage for both types of rearrangements was analyzed by polymerase chain reaction and sequencing. RESULTS: VH3 and VH1 family members were over- and under-represented, respectively. VH3-30 and VH3-15 segments were the most frequently used, whereas VH4-34 was found only in non-functional or heavily mutated VDJH rearrangements. DH2 and DH3 family members were over-represented in both VDJH and DJH repertoires, while the DH1 family was under-represented only in the productive VDJH rearrangements. Finally, DH3-22 and DH2-21 gene segments were found to be over-represented in the functional repertoire while segments commonly used by less mature B-cell malignancies, such as DH6-19 or DH3-3, were under-represented. INTERPRETATION AND CONCLUSIONS: Data reported here help to identify the clonogenic MM cell as a post-germinal center B cell that has undergone selection processes during the germinal center reaction.

Preserving the cultural heritage of the performing arts raises difficult and sensitive issues, as each performance is unique by nature and the juxtaposition between the performers and the audience cannot be easily recorded. In this paper, we report on an experimental research project to preserve another aspect of the performing arts—the history of their rehearsals. We have specifically designed non-intrusive video recording and on-site documentation techniques to make this process transparent to the creative crew, and have developed a complete workflow to publish the recorded video data and their corresponding meta-data online as Open Data using state-of-the-art audio and video processing to maximize non-linear navigation and hypervideo linking. The resulting open archive is made publicly available to researchers and amateurs alike and offers a unique account of the inner workings of the worlds of theater and opera.

A gulf has tended to develop between the adoption and usage of information technology by different generations, at the heart of which is different ways of experiencing and relating to the world around us. This research idea is currently being developed following data collection and feedback is sought on ways forward to enable impact. The research focuses on information technology in the form of multimedia. Multimedia meaning ‘media’ and ‘content’ that uses a combination of different content forms; or electronically integrated communication engaging all or most of the senses (e.g. graphic art, sound, animation and full-motion video presented by way of computer or other electronic means) mainly through presentational technologies. Although multimedia is not new, some organization’s particularly those in the non-profit sector do not always have the technical or financial resources to support such systems and consequently may struggle to adopt and support its usage amongst different generations. However non-profit organizations are being forced to pay more attention to the way they communicate with markets and the public due to the professionalism of communication everywhere in society. The case study used for this study is a church circuit comprising of 15 churches in the Midlands region of the United Kingdom which was selected due to the diverse age groups catered for within this type of non-profit organization. Participants in the study also had a range of skills, experiences and backgrounds which adds to the diversity of the population studied. Data gathered focused on the attitudes and opinions of the adoption and use of multimedia amongst different age groups. 395 questionnaires were distributed, comprising of 11 opinion questions and 4 demographic questions. 83% of the questionnaires were returned, representing 35% of the total circuit membership. Three people from each of the following age categories were also interviewed: 1920 – 1946 (Matures); 1947-1964 (Baby Boomers); 1965-1982 (Generation X); 1983-2004 (Net Generation). Results of the questionnaire and comments from the interviews were found not to tally with the widespread assumption that the younger generation is attracted by the use of multimedia in comparison to the older generation. The highest proportion of those who said that they gain more from a service enhanced by multimedia was from the Baby Boomers. Comments from interviews suggested that: ‘we need to embrace multimedia if we are to attract and retain the younger generation’; ‘multimedia often helps children to remain focused and clarifies the objective of the service’. However, because the younger generations’ world tends to be dominated by computer technology the questionnaire showed that they are more likely to have higher standards when it comes to the use of multimedia, such as identifying higher levels of equipment failing to work and annoying use of sounds compared to older age groups. In comparison problems experienced with multimedia for the Matures age group had the highest percentage of difficulty with the size of letters; the colour of letters and background and the sound not loud enough which is to be expected. Since every organization is unique any type of multimedia adopted and used should be specific to their needs, its stakeholders and the physical building in order to enhance that uniqueness and its needs. Giving thought to whether the type of multimedia is the best method for communicating the message to the particular audience alongside how technical and financial resources are best used can assist in accommodating different age groups that need to be catered for.

Recent evidences indicate that tRNA modifications and tRNA modifying enzymes may play important roles in complex human diseases such as cancer, neurological disorders and mitochondrial-linked diseases. We postulate that expression deregulation of tRNA modifying enzymes affects the level of tRNA modifications and, consequently, their function and the translation efficiency of their tRNA corresponding codons. Due to the degeneracy of the genetic code, most amino acids are encoded by two to six synonymous codons. This degeneracy and the biased usage of synonymous codons cause alterations that can span from protein folding to enhanced translation efficiency of a select gene group. In this work, we focused on cancer and performed a meta-analysis study to compare microarray gene expression profiles, reported by previous studies and evaluate the codon usage of different types of cancer where tRNA modifying enzymes were found de-regulated. A total of 36 different tRNA modifying enzymes were found de-regulated in most cancer datasets analyzed. The codon usage analysis revealed a preference for codons ending in AU for the up-regulated genes, while the down-regulated genes show a preference for GC ending codons. Furthermore, a PCA biplot analysis showed this same tendency. We also analyzed the codon usage of the datasets where the CTU2 tRNA modifying enzyme was found deregulated as this enzyme affects the wobble position (position 34) of specific tRNAs. Our data points to a distinct codon usage pattern between up and downregulated genes in cancer, which might be caused by the deregulation of specific tRNA modifying enzymes. This codon usage bias may augment the transcription and translation efficiency of some genes that otherwise, in a normal situation, would be translated less efficiently.

The article reflects on a pilot teacher training programme in Tanzania, where videos are used for implementing new teaching methods, but also for initiating a discourse about corporal punishment. The culture of instruction in Tanzania is strictly based on a teacher-centred approach which leaves all activity to the teacher and turns students into passive listeners. In most cases, teachers deal with up to 80 students in one classroom. Therefore, discipline is an important matter of instruction and many teachers still use corporal punishment that is widely accepted in Tanzania. The launched training programme has the aim of implementing learner-centred teaching methods without using corporal punishment and offers Tanzanian teachers the possibility to participate in a workshop that connects these methods with subject-related topics. In the English teaching workshop, the facilitator used filmed English lessons from a German school to discuss with the participants both the application of learner-centred methods and the absence of corporal punishment. The use of these German videos shows advantages but also limitations that are strongly related to the European versus African setting. The article discusses these dimensions on the basis of data that are generated by ethnographical observation and audiotranscripts of the piloted workshop.

Scientific research is increasingly data-intensive, relying more and more upon advanced computational resources to be able to answer the questions most pressing to our society at large. This report presents findings from a brief descriptive survey sent to a sample of 342 leading researchers at the University of Washington (UW), Seattle, Washington in 2010 and 2011 as the first stage of the larger National Science Foundation project “Interacting with Cyberinfrastructure in the Face of Changing Science.” This survey assesses these researcher’s use of advanced computational resources, data, and software in their research. We present high-level findings that describe UW researchers’: demographics, interdisciplinarity, research groups, data use, software and computational use—including software development and use, data storage and transfer activities, and collaboration tools, and computing resources. These findings offer insights into the state of computational resources in use during this time period as well as offering a look at the data intensiveness of UW researchers.

The high degree of variability and inconsistency in cash flow study usage by property professionals demands improvement in knowledge and processes. Until recently limited research was being undertaken on the use of cash flow studies in property valuations but the growing acceptance of this approach for major investment valuations has resulted in renewed interest in this topic. Studies on valuation variations identify data accuracy, model consistency and bias as major concerns. In cash flow studies there are practical problems with the input data and the consistency of the models. This study will refer to the recent literature and identify the major factors in model inconsistency and data selection. A detailed case study will be used to examine the effects of changes in structure and inputs. The key variable inputs will be identified and proposals developed to improve the selection process for these key variables. The variables will be selected with the aid of sensitivity studies and alternative ways of quantifying the key variables explained. The paper recommends, with reservations, the use of probability profiles of the variables and the incorporation of this data in simulation exercises. The use of Monte Carlo simulation is demonstrated and the factors influencing the structure of the probability distributions of the key variables are outline. This study relates to ongoing research into functional performance of commercial property within an Australian Cooperative Research Centre.

The issue of whether improved building services such as air quality, provision of daylight, thermal comfort etc, have a positive impact on the health and productivity of building occupants is still an open question. There is significant anecdotal evidence supporting the notion that health and productivity of building occupants can be improved by improving the quality of the indoor environment, but there are actually few published quantitative studies to substantiate this contention. This paper reports on a comprehensive review of the worldwide literature which relates health of building occupants with the different aspects of the indoor environment which are believed to impact of these issues, with a particular focus on studies in Australia, The paper analyses the existing research and identifies the key deficiencies in our existing understanding of this problem. The key focus of this research is office and school buildings, but the scope of the literature surveyed includes all commercial buildings, including industrial buildings. There is a notable absence of detailed studies on this link in Australian buildings, although there are studies on thermal comfort, and a number of studies on indoor air quality in Australia, which do not make the connection to health and productivity. Many international studies have focused on improved lighting, and in particular the provision of daylight in buildings, but again there are few studies in Australia which focus in this area.
