Human exposure assessment in the near field of GSM base-station antennas using a hybrid finite element/method of moments technique

A hybrid finite-element method (FEM)/method of moments (MoM) technique is employed for specific absorption rate (SAR) calculations in a human phantom in the near field of a typical group special mobile (GSM) base-station antenna. The MoM is used to model the metallic surfaces and wires of the base-station antenna, and the FEM is used to model the heterogeneous human phantom. The advantages of each of these frequency domain techniques are, thus, exploited, leading to a highly efficient and robust numerical method for addressing this type of bioelectromagnetic problem. The basic mathematical formulation of the hybrid technique is presented. This is followed by a discussion of important implementation details-in particular, the linear algebra routines for sparse, complex FEM matrices combined with dense MoM matrices. The implementation is validated by comparing results to MoM (surface equivalence principle implementation) and finite-difference time-domain (FDTD) solutions of human exposure problems. A comparison of the computational efficiency of the different techniques is presented. The FEM/MoM implementation is then used for whole-body and critical-organ SAR calculations in a phantom at different positions in the near field of a base-station antenna. This problem cannot, in general, be solved using the MoM or FDTD due to computational limitations. This paper shows that the specific hybrid FEM/MoM implementation is an efficient numerical tool for accurate assessment of human exposure in the near field of base-station antennas.
Regionalization of National Input–Output Tables: Empirical Evidence on the Use of the FLQ Formula

Kowalewksi J. Regionalization of national input–output tables: empirical evidence on the use of the FLQ formula, Regional Studies. Flegg's location quotient (FLQ) can be used to simulate regional input–output tables, and this paper contributes to the ongoing debate about deriving values for the exponent δ in this formula. Using a survey-based regional input–output table, values of δ are derived for the German federal state of Baden-Wuerttemberg. Furthermore, an extended formula – called industry-specific FLQ (SFLQ) – is introduced which allows for variation in δ by industry. Finally, the advantage of the SFLQ is demonstrated and evidence is found of a close relationship between the spatial concentration of an industry at the national level and its propensity to import goods and services from other regions.
Contributions of work stressors, alcohol, and normative beliefs to partner violence.

OBJECTIVE A body of research has established that lower socioeconomic populations, including blue-collar workers, are at higher risk for problem drinking and intimate partner violence. This study of married/cohabiting construction workers and their spouses/partners describes how work stressors, hazardous drinking, and couple characteristics interact to influence normative beliefs around partner violence and, thereafter, its occurrence. METHOD Our survey respondents from a sample of 502 dual-earner couples were asked about drinking patterns, past-year partner violence, normative beliefs about partner violence, work-related stressors, impulsivity, and childhood exposure to violence and other adverse events. We conducted semi-structured qualitative interviews with 81 workers on context of work stress, partner violence, and drinking. RESULTS Analyses of data revealed that men's and women's normative beliefs about partner violence were positively related to maleto- female partner violence; female partner violence normative beliefs were associated with female-to-male partner violence. Both partners' levels of impulsivity were directly associated with male-to-female and female-to-male partner violence, and male partner's frequency of intoxication mediated the association between level of impulsivity and male-to-female partner violence. Female partner's adverse childhood experience was directly associated with male-to-female partner violence. Both survey and qualitative interviews identified individual and workrelated factors that influence the occurrence of violence between men and women. DISCUSSION These findings provide guidelines for prevention of partner violence that can be implemented in the workplace with attention to hazardous drinking, job stress, treatment, education, and work culture.
Counting the costs of HIV and AIDS to civil-society organisations

HIV threatens the survival of many civil-society organisations (CSOs) in Africa. While we know the range of potential costs to such groups, we lack a detailed picture of the extent of the impact. This article highlights important findings from exploratory research in Malawi. Respondents perceived that overall performance in the four CSOs studied declined by an average 20 per cent because they were working in a context of high HIV prevalence. Yet the CSOs' workplace response to this threat was very limited, and they remain highly vulnerable to future impact. We consider why the CSOs have not been more proactive, and we recommend that donor policy should help partners to respond to the epidemic and enable them to remain effective.
Seasonal climate prediction for North Eurasia

An overview of the current status of the operational seasonal climate prediction for North Eurasia is presented. It is shown that the performance of existing climate models is rather poor in seasonal prediction for North Eurasia. Multi-model ensemble forecasts are more reliable than single-model ones; however, for North Eurasia they tend to be close to climatological ones. Application of downscaling methods may improve predictions for some locations (or regions). However, general improvement of the reliability of seasonal forecasts for North Eurasia requires improvement of the climate prediction models.
The State and New-build Gentrification in Central Cape Town, South Africa

The objective of this investigation is to assess the relevance and potential of current international trends in the study of gentrification in the contemporary South African urban context. Against the backdrop of `new' gentrification experiences and debates it is argued that recent developments in the central-city districts of large South African cities present numerous opportunities for `new' gentrification processes to emerge as a central part of urban regeneration. Moreover, it is contended that specific state policies and interventions focused on inner-city regeneration underpin new forms of gentrification in South Africa.
Communicating the psychological contract: an employer perspective

The concept of the psychological contract, with its focus on the exchange of perceived promises and commitments, is increasingly used as a framework to study the employment relationship. Yet research has predominantly focused on employee views and has largely neglected the organisational perspective and the management of the psychological contract. This article begins to redress the balance by reporting a study, based on a survey of 1,306 senior HR managers, that explores the management of the psychological contract and in particular the role of organisational communication. Three distinct and relevant aspects of organisational communication are identified, concerned with initial entry, day-to-day work and more future-oriented, top-down communication. Effective use of these forms of communication is associated with what managers judge to be a clearer and less frequently breached set of organisational promises and commitments, as well as with a fairer exchange and a more positive impact of policies and practices on employee attitudes and behaviour. The findings are discussed within the context of the wider literature on psychological contracts, organisational culture and HRM. The study confirms that the psychological contract offers managers a useful framework within which to consider and manage the employment relationship.
Ancestors, Domestic Groups, and the Socialist State: Housing Nationalization and Restitution in Romania

As in the vast majority of socialist states that arose with the Soviet Union's post-World War II hegemony over Eastern Europe, People's Republic of Romania nationalized (confiscated) a large number of privately owned houses. The declared intention of the state was to eliminate housing inequality and the private rental sector in urban areas. In 1950, the state appropriated both leased and family homes that were considered to have too much domestic space. The inhabitants of confiscated houses became tenants instead of owners. Tenants were made to live with the former owners in such expropriated domestic space. With the collapse of state socialism in 1989, former owners and their descendants began seeking to regain the property rights for these confiscated houses. In a limited number of cases they succeeded, although the majority of houses had been sold by the state to the sitting tenants at very low prices.
Second-Order Cone Programming Relaxation of Sensor Network Localization

The sensor network localization problem has been much studied. Recently Biswas and Ye proposed a semidefinite programming (SDP) relaxation of this problem which has various nice properties and for which a number of solution methods have been proposed. Here, we study a second-order cone programming (SOCP) relaxation of this problem, motivated by its simpler structure and its potential to be solved faster than SDP. We show that the SOCP relaxation, though weaker than the SDP relaxation, has nice properties that make it useful as a problem preprocessor. In particular, sensors that are uniquely positioned among interior solutions of the SOCP relaxation are accurate up to the square root of the distance error. Thus, these sensors, which are easily identified, are accurately positioned. In our numerical simulation, the interior solution found can accurately position up to 80-90p of the sensors. We also propose a smoothing coordinate gradient descent method for finding an interior solution that is faster than an interior-point method.
WHY DON'T POOR COUNTRIES CATCH UP? A CROSS‐NATIONAL TEST OF AN INSTITUTIONAL EXPLANATION

Early neoclassical analyses predicted that poor countries would grow faster than wealthy countries because of technological advances and diminishing returns to capital in the latter. The reverse has occurred: poor countries are falling back rather than catching up. The authors suggest here that deficient institutions underlie this divergence. Employing various indicators of institutional quality, including the rule of law, the pervasiveness of corruption, and the risk of expropriation and contract repudiation, they show that the ability of poor countries to catch up is determined in large part by the institutional environment in which economic activity in these countries takes place.

Fatty Acid Profile of Neutral and Polar Lipid Fraction of Wild Eggs and Hatchlings from Wild and Captive Reared Broodstock of Octopus vulgaris

The culture of Octopus vulgaris is constrained by unsolved problems in paralarvae rearing, mainly associated to the unknown nutritional requirements of this species in early stages. In this article we studied the fatty acid profile (total, neutral, and polar lipid fractions) in wild eggs and wild hatchlings, collected in Gran Canaria (SW) (Spain) with artificial dens, in comparison to hatchlings obtained in captivity from broodstock fed on trash fish species. Total lipids were 11.5–13.5% dw, with the polar fraction representing a 70.6–75.5% of total lipid, with lower values in wild hatchling in comparison with captive ones. Docosahexaenoic acid (DHA) was the main component in neutral and polar fatty acid profile in all samples, underlying its importance in this species. Decreasing levels of saturates and arachidonic acid (ARA) from wild eggs to hatchlings, mainly associated to the polar fraction, suggest their use during embryonic development. In hatchlings, increasing levels of oleic acid in the neutral fraction and eicosapentaenoic acid (EPA) in the polar fraction, suggests their importance in hatchlings quality. Wild hatchlings showed in the polar fraction higher oleic acid and ARA, and lower DHA/ARA and EPA/ARA ratios in comparison with captive hatchlings, suggesting a difference in paralarvae nutritional status. These results suggest the importance of n-3 highly unsaturated fatty acids (HUFA), oleic acid, and ARA, presented in the adequate lipid fraction, in the diet of broodstock and paralarvae of O. vulgaris.
Government Alternation and Legislative Party Unity: The Case of Italy, 1988–2008

The large literature on legislative party unity identifies the confidence relationship, i.e. the threat of being voted out of office and losing agenda setting powers, as well as cabinet membership, as two crucial institutional sources of party discipline. However, by focusing on the dramatic change in the Italian political system following the 1994 election, the article shows that the impact of these factors on party unity (and the direction of this impact) hinge crucially on the possibility of government alternation rather than mere cabinet turnover. This is illustrated by an index of party unity that explicitly focuses on the behaviour of individual MPs derived from a roll-call analysis of the Italian Chamber of Deputies during the period 1988–2008.
The effects of increasing cell length on auxotonic contractions; membrane potential and intracellular calcium transients in single guinea‐pig ventricular myocytes

Until recently the investigation of length‐dependent effects in cardiac muscle was restricted to multicellular preparations. We describe our experimental set‐up which for the first time, in single cardiac myocytes, permits the effects of changes in cell length on auxotonic contractions (measured by carbon fibre transducers) to be simultaneously recorded with the effects on membrane potential and/or changes in intracellular calcium concentration (using indo‐1 AM, acetoxylmethyl form). Consistent with previous findings (in experiments at 20‐25 degrees C and 0.25 Hz) we report that following a stretch there was an increase in passive tension and contraction. A stretch which increased sarcomere length by approximately 3% had no significant effect on resting membrane potential or action potential amplitude. There was, however, a significant decrease in the action potential duration (P < 0.01, n = 8). No significant change in the amplitude of the intracellular calcium transient was seen following a stretch but a reduction in its duration was observed (P < 0.025, n = 11). Our observations on intracellular calcium transients are consistent with the hypothesis that, in mechanically loaded preparations, their time course is more dependent on changes in tension than changes in length.
NNNLO soft-gluon corrections for the top-quark p T and rapidity distributions

I present a calculation of next-to-next-to-next-to-leading-order (NNNLO) soft-gluon corrections for differential distributions in top-antitop pair production in hadronic collisions. Approximate NNNLO (aNNNLO) results are obtained from soft-gluon resummation. Theoretical predictions are shown for the top-quark aNNNLO transverse momentum ($p_T$) and rapidity distributions at LHC and Tevatron energies. The aNNNLO corrections enhance previous results for the distributions but have smaller theoretical uncertainties.
Competition in the Computer Industry: Online versus Retail

This paper estimates the price sensitivity of individuals' choice of whether to buy computers online versus in retail stores using a new data source on the computer purchases of more than 20,000 people. The paper first fits hedonic regressions for the retail price of computers in a local area and then examines how that price influences the probability of buying online. The results indicate that the decision is sensitive to the relative price of retail computers and it varies by type of customer and type of computer. Conditional on buying a computer, the elasticity of buying remotely with respect to retail store prices is about 1.5. Copyright 2001 by Blackwell Publishing Ltd
Quantifying the Effect of Financial Conditions in the Euro Area, Japan, United Kingdom and United States

This paper constructs a broad measure of financial conditions for the United States, Japan, the Euro Area and the United Kingdom, by extending monetary condition indices which are traditionally used to gauge the impact of monetary policy on the economy. In addition to changes in the exchange rate and short and long interest rates, the change in credit availability, corporate bond spreads and household wealth are taken into account to gauge the evolution of financial conditions. Since the onset of the financial crisis, financial conditions have tightened by an unprecedented degree in the four countries/regions and this is evaluated to exert a major drag on activity.
Exploring within-tree architectural development of two apple tree cultivars over 6 years.

The present study addresses the prediction of apple tree development, taking into account both the number and within-tree position of tree components. The architectural development of two trees per scion cultivar, 'Fuji' and 'Braeburn', was studied by describing all shoots over 6 years. Flowering and fruiting were observed over 3 years. The description included different scales [entire trees, axes, growth units (GUs) and metamers], and the analysis compared all axes of the trees as a function of their branching order and age. Three main aspects of vegetative development were investigated: the quantity of primary growth; the number and nature of developing axillary shoots; and meristem death. Results confirm the existence of within-tree morphological gradients, and show that the decrease in growth was comparable in magnitude for all axes and GUs, irrespective of their position. This decrease results from a reduction in the number of metamers per GU, which was modelled by an exponential function. The decrease in growth involved changes in the number and nature of the axillary shoots, which could be described by simple functions. The probability of spur death was constant over the years but differed according to cultivar and type of bearing shoot. The within-tree probability of flowering and fruiting was predictable for 'Braeburn' because axes, regardless of their position and type, had a high probability of flowering and a low probability of fruit set which led to a regular bearing habit. In contrast, 'Fuji' had an alternating bearing behaviour that was more complex to predict. This appeared to result from a synchronized increase in the probability that all GUs at tree scale are floral, combined with a high probability of fruit set. The consequences of these results for both yield prediction and architectural simulations are discussed.
Comparing Standards of Business Ethics in USA, China, Jamaica and Pakistan

As the business organizations are expanding at a rapid pace, so is the circulation of human resources the world over. Managers and workers are required to work in different socio-economic environments which, at times, may not be similar to those of their home countries. It is imperative therefore for business organizations and individuals to acquire in depth knowledge about the culture and business ethics prevailing in the country of interest. A number of scholars have undertaken research studies to compare the standards of Business Ethics of different countries but such a research on “the Standards of Business Ethics” has been carried out for the first time in Pakistan. Interestingly, either such studies have been carried out in developed countries like Europe, America and Far East or the researchers have been from these countries. The conduct of such a study in Pakistan by a Pakistani would be the first of its nature. Some of the internationally accepted norms have been used as scenarios and respondents have been asked to indicate possibility of their reaction to take action. They have also been asked to give rationale of their decision. An effort has been made in this study, to compare the standards of business ethics of Pakistani business professionals with those of other countries of the world. This would help adjudge differences and similarities of well-established universal norms and ethics prevailing in the world business community. It is expected that this and more such studies would help researchers and business professionals develop good and desirable business practices in Pakistan.Comparing and enhancing awareness about standards of business ethics in Pakistan is the main objective of this research. It is expected that this humble effort would encourage many more researchers to dive deep into the ocean of business ethics.
A genetic perspective on glucose consumption in the cerebral cortex during human development

As the major glucose‐consuming organ in the human body, the dynamics of glucose metabolism in the brain deserve special attention. It has been shown that the brain's energy allocation as a percentage of the total energy budget of the individual peaks during childhood and declines through adolescence until reaching the stable allocation level seen in the adult. This pattern of glucose consumption has not been observed in other species, including our close primate relatives, and is therefore potentially either a driver or a consequence of human cognition. Furthermore, the allocation of glucose usage in the brain changes as the individual ages, with a surprising amount dedicated to glycolysis rather than oxidative phosphorylation pathway. This suggests that, at certain developmental stages, glucose‐fuelled anabolic pathways, in addition to ATP generation, are the driving forces behind the brain's high energy requirement. In this study, we explore the most recent work pertaining to the dynamic glucose uptake and allocation of the developing human brain and investigate several genes that may play a role in regulating these processes.
Are stocks really riskier than bonds?

Conventional wisdom holds that stocks are riskier than bonds; thus when the stock market becomes volatile, money flows from the stock market into the perceived safe haven of the bond market. In this article, we find that this notion is not necessarily accurate and might lead people to make incorrect investment decisions. In fact, intermediate- and long-term bonds are riskier than stocks when we measure risk by the coefficient of variation. We examine a case where an inaccurate perception regarding the relative riskiness of the two types of assets could play a part in what appears to be short-sighted and potentially costly behaviour of investors in financial markets.
Biotechnology and food safety in China : Consumers' acceptance or resistance?

Although China is one of the world's largest producers and consumers of genetically modified (GM) crops and derived food products, little is known about the level of Chinese consumer awareness, understanding and acceptance of GM food. Initially, China pursued relatively aggressive policies for biotechnology development, but in recent years, the central government has become more sensitive to the potential environmental risks of transgenic food crops. To protect domestic biotech industries, the state plays a critical role in the politics of biotechnology, and does not allow GM food to become a prominent public issue. This contribution reports on a survey of 1,000 urban respondents. It demonstrates that most consumers lack the most basic understanding of biotechnology and its potential risks. The majority of the respondents (60 per cent) were either unwilling to consume GM food or were neutral about the idea, but when given neutrally-worded information about potential GM food allergenicity, the willingness to buy dropped sharply. This might point to future scenarios of consumer resistance against GM food as has happened in European Union member states. This effect demonstrates the malleability of the Chinese consumer in a context of limited understanding and inadequate access to information.
