Lars Vegard:key communicator and pioneer crystallographer

The Norwegian physicist Lars Vegard studied with William H. Bragg in Leeds and then with Wilhelm Wien in Würzburg. There, in 1912, he heard a lecture by Max Laue describing the first X-ray diffraction experiments and took accurate notes which he promptly sent to Bragg. Although now remembered mainly for his work on the physics of the aurora borealis, Vegard also did important pioneering work in three areas of crystallography. He derived chemical insight from a series of related crystal structures that he determined, Vegard's Law relates the unit-cell dimensions of mixed crystals to those of the pure components, and he determined some of the first crystal structures of gases solidified at cryogenic temperatures. © 2013 Taylor and Francis.

"Quality lives on":quality initiatives and practices in Australia and Britain

Purpose-The purpose of this research is to explore the incidence of innovative approaches to quality in both Australia and Britain, the reasons behind their implementation, the ways in which they were undertaken and the success factors and the pitfalls encountered along the way. Design/methodology/ approach-A structured postal questionnaire was sent to 1,000 quality managers in both Australia and Britain. A response was received from 129 Australian and 175 British companies, who reported on why they did or did not introduce a new quality initiative within the past five years. Findings-A comparative analysis shows trends, similarities and differences, and future directions of quality in both countries. The paper concludes by identifying important lessons for senior management needing to make changes in this important aspect of any business. A high proportion of organisations in both countries are actively undertaking new quality initiatives. The impetus to change and the barriers to successful implementation were common to both countries. The type of initiative differed between the two countries, with a preponderance of ISO 9000 in Australia amongst a much wider choice of approaches than in Britain. There is a low take-up of Six Sigma in both countries, particularly in Australia. Originality/value-The paper offers a recent insight into quality approaches undertaken in both countries and identifies important lessons for senior management. © 2010 Emerald Group Publishing Limited.

A szervezeti elkötelezettség és a munka-család viszonyrendszer összefüggései (The relationship between organizational commitment and work-life balance)

376 ügyfélszolgálati dolgozó bevonásával végzett kérdőíves vizsgálatukban a szerzők arra keresték a választ, hogy a szervezeti elkötelezettség profilok hogyan függnek össze a munkahelyi elégedettséggel, a kilépési szándékkal és a munka-család viszonyrendszerre vonatkozó változókkal (munka-család konfliktus, munkacsalád egyensúly, munka-család gazdagítás). Nyolc különböző profilt találtak, amelyek elemzéséből kiderült: az elkötelezettség-komponensek közül az érzelmi elkötelezettségnek kitüntetett szerepe van a kedvező következményeket tekintve, továbbá az elkötelezettségkomponensek együttes hatása szinergikus lehet. ________ In their research that was based on the answers of 376 customer service employees to a questionnaire survey, the authors are looking at the relationship between the organizational commitment profiles and work satisfaction, intention to leave the organization and various subconcepts of work life balance (work-family conflict, work-family balance and work-family enrichment). They have found 8 different profiles, the analysis of which revealed the central role of the affective component regarding the positive outcomes of the above mentioned variables as well as the synergic relations among the different components of organizational commitment.

Dynamic Behavior and Fatigue Life of Highway Bridges Due to Doubling Heavy Vehicles

An increase in the demand for the freight shipping in the United States has been predicted for the near future and Longer Combination Vehicles (LCVs), which can carry more loads in each trip, seem like a good solution for the problem. Currently, utilizing LCVs is not permitted in most states of the US and little research has been conducted on the effects of these heavy vehicles on the roads and bridges. In this research, efforts are made to study these effects by comparing the dynamic and fatigue effects of LCVs with more common trucks. Ten Steel and prestressed concrete bridges with span lengths ranging from 30’ to 140’ are designed and modeled using the grid system in MATLAB. Additionally, three more real bridges including two single span simply supported steel bridges and a three span continuous steel bridge are modeled using the same MATLAB code. The equations of motion of three LCVs as well as eight other trucks are derived and these vehicles are subjected to different road surface conditions and bumps on the roads and the designed and real bridges. By forming the bridge equations of motion using the mass, stiffness and damping matrices and considering the interaction between the truck and the bridge, the differential equations are solved using the ODE solver in MATLAB and the results of the forces in tires as well as the deflections and moments in the bridge members are obtained. The results of this study show that for most of the bridges, LCVs result in the smallest values of Dynamic Amplification Factor (DAF) whereas the Single Unit Trucks cause the highest values of DAF when traveling on the bridges. Also in most cases, the values of DAF are observed to be smaller than the 33% threshold suggested by the design code. Additionally, fatigue analysis of the bridges in this study confirms that by replacing the current truck traffic with higher capacity LCVs, in most cases, the remaining fatigue life of the bridge is only slightly decreased which means that taking advantage of these larger vehicles can be a viable option for decision makers.

Genetics and the Life Course

A life-course perspective is committed to the proposition that from conception to death, all human outcomes are the result of a continual interaction between the indi- vidual and all of the environments that he or she inhabits at any given point in time. Early development is a critical period, a window of time during the life course when a given exposure can have a critical or permanent in uence on later outcomes. But the impact of exposures upon outcomes does not end at any speci c point in time, inasmuch as life is a continuing interactive and adaptive process. We now know that what applies to human beings also applies to their genomes. The “outcome” of any gene at any given point in time (whether or not it is used to transcribe a particular protein, what form of that protein, and how much) is a product of the interaction between the gene and the multiple environments of which it is a part, which include the epigenome, the cell, the biological human, and the assorted environments he or she occupies (e.g., geographical, socioeconomic, ethnic, etc.). Early life experiences can permanently “reprogram” the epigenome and gene transcription with life-long behavioral consequences. At the same time, the epigenome as well as the genome continue to be environmentally responsive throughout the life course.

Age and Life Course Location as Interpretive Resources for Decisions Regarding Disclosure of HIV to Parents and Children: Findings from the HIV and Later Life Study

Studies of disclosure among older people living with HIV (PLWH) are uninformed by critical social-gerontological approaches that can help us to appreciate how older PLWH see and treat age as relevant to disclosure of their HIV status. These approaches include an ethnomethodologically-informed social constructionism that explores how ‘the’ life course (a cultural framework depicting individuals’ movement through predictable developmental stages from birth to death) is used as an interpretive resource for determining self and others’ characteristics, capacities, and social circumstances: a process Rosenfeld and Gallagher (2002) termed ‘lifecoursing’. Applying this approach to our analysis of 74 life-history interviews and three focus groups with older (aged 50+) people living with HIV in the United Kingdom, we uncover the central role that lifecoursing plays in participants’ decision-making surrounding disclosure of their HIV to their children and/or older parents. Analysis of participants’ accounts uncovered four criteria for disclosure: the relevance of their HIV to the other, the other’s knowledge about HIV, the likelihood of the disclosure causing the other emotional distress, and the other’s ability to keep the disclosed confidential. To determine if these criteria were met in relation to specific children and/or elders, participants engaged in lifecoursing, evaluating the other’s knowledge of HIV, and capacity to appropriately manage the disclosure, by reference to their age. The use of assumptions about age and life-course location in decision-making regarding disclosure of HIV reflects a more nuanced engagement with age in the disclosure decision-making process than has been captured by previous research into HIV disclosure, including on the part of people aging with HIV.

On Queueinginventory Models – product form solution; reservation, Cancellation and common life time

Queueing theory is the mathematical study of ‘queue’ or ‘waiting lines’ where an item from inventory is provided to the customer on completion of service. A typical queueing system consists of a queue and a server. Customers arrive in the system from outside and join the queue in a certain way. The server picks up customers and serves them according to certain service discipline. Customers leave the system immediately after their service is completed. For queueing systems, queue length, waiting time and busy period are of primary interest to applications. The theory permits the derivation and calculation of several performance measures including the average waiting time in the queue or the system, mean queue length, traffic intensity, the expected number waiting or receiving service, mean busy period, distribution of queue length, and the probability of encountering the system in certain states, such as empty, full, having an available server or having to wait a certain time to be served.

The New Scots: Migration and Diaspora in Scottish Poetry.

This chapter examines the poetry of Scottish South Asians, the "New Scots" who bring a whole history of displacement, dislocation and relocation with them, as their memory of the "elsewhere" enters their writing. Their voices are significant as they embody multicultural Scotland with postcolonial dialects that signify an encounter in the Third Space where they are affected by and affect the "host" community. This chapter will question whether the writing of "New Scots" has added more than just "colour" to Scottish Poetry, as it traces the recent migrant history and analyses the lives and "voices" of diasporic communities as evident in their poetry. The objective is to assess how the new "voices" have blended in, expanded and/or challenged the boundaries of what defines Scottish Poetry, and determine whether they form a "community" of poets distinguished by the complexity of their regional allegiances, both past and present.
