A novel phase shifter for 60 GHz phased arrays

This paper presents a novel active phase shifter circuit topology based on LC all-pass lattice filter with variable inductors and capacitors within an amplifier. By tuning properly the inductance and capacitance of the filter it is possible to shift the input signal by the desired amount of phase from 0° to 180°. The preliminary design of a 60-GHz 8-phase phase shifter with phase resolution 22.5° from 0° to 157.5° has been carried in 28nm FDSOI CMOS by STMicroelectronics in order to demonstrate the validity of the proposed idea. Simulation results show an average gain of 15 dB at 60.8 GHz, a 3 dB bandwidth of 12 GHz, RMS gain error and RMS phase error lower than 1.8 dB and 12° in band. Simulations of the normalized gain pattern of a 4-element phased array with the proposed phase shifter show a deviation of the beam steering angle lower than 6° with respect to the ideal phase shifts.
The Contribution of ‘Social Capital’ to Economic Growth: Lessons from Island Jurisdictions

This paper is concerned with the relationship of ‘social capital’ to economic development, with a deliberate focus on island territories. It argues that an appreciation of ‘social capital’ theory makes for a more informed understanding of how many (though not all) small, peripheral and network-driven island societies develop ‘good governance’ practices and manage a commendable standard of living. ‘Island neo-corporatism’ merits recognition on its own terms as the deep structure to ‘good governance’; and, in combination with jurisdictional powers, it is a key primer of economic development.
Research Synthesis in Sport Management: Dealing with “Chaos in the Brickyard”

Abstract Interest in research synthesis as a primary research endeavour is increasing in many areas of the social sciences. However, it has not been widely employed in the field of sport management. This review paper outlines the uses of research synthesis and discusses three approaches that might be particularly appropriate to sport management researchers: systematic review, meta-analysis and meta-interpretation. A brief overview of each of these approaches is given prior to the discussion of a range of examples and applications from previous sport management research. The utility of research synthesis in making sense of diverse research areas is highlighted along with its potential to ensure full use is made of existing research findings. In conclusion, the need for research synthesis to be synergistic is discussed.
The Interplay between Online and Offline Explorations of Identity, Relationships, and Sex: A Mixed-Methods Study with LGBT Youth

Although the Internet is commonly used by lesbian, gay, bisexual, and transgender (LGBT) youth to explore aspects of sexual health, little is known about how this usage relates to offline explorations and experiences. This study used a mixed-methods approach to investigate the interplay between online and offline explorations of multiple dimensions of sexual health, which include sexually transmitted infections, sexual identities, romantic relationships, and sexual behaviors. A diverse community sample of 32 LGBT youth (ages 16–24) completed semi-structured interviews, which were transcribed and then qualitatively coded to identify themes. Results indicated that, although many participants evaluated online sexual health resources with caution, they frequently used the Internet to compensate for perceived limitations in offline resources and relationships. Some participants turned to the Internet to find friends and romantic partners, citing the relative difficulty of establishing offline contact with LGBT peers. Further, participants perceived the Internet as an efficient way to discover offline LGBT events and services relevant to sexual health. These results suggest that LGBT youth are motivated to fill gaps in their offline sexual health resources (e.g., books and personal communications) with online information. The Internet is a setting that can be harnessed to provide support for the successful development of sexual health.
The macroeconomic effects of adjustment lending: A review and evaluation

Does external aid have an impact on economic growth, if so, through what channels? Does the domestic policy environment matter? In the past ten years, these questions have been the subject of a large number of empirical studies. This article surveys these studies and identifies the areas where there is consensus and those where there is not. It is argued that to move forward, empirical work must be based more explicitly on structural models of the link between aid and growth, notably by incorporating relationships between aid, government fiscal responses, private sector investment, and economic growth.
DETERMINANTS OF WELFARE POLICY ATTITUDES: A CONTEXTUAL LEVEL ANALYSIS

Using the 2008 Chicago Area Study, this article tests how residential context plays a role in welfare policy attitudes, controlling for individual level characteristics. The contextual level variables of household public assistance use and minority concentration in respondents' neighborhoods are tested using multinomial logistic regression analysis. When including controls for education, income, political party, age, employment status, gender, and race, respondents residing in neighborhoods with a higher concentration of African Americans are more likely to endorse positive attitudes toward welfare policy. Additionally, an interaction effect is found between individual level income and household public assistance use in the ZIP code when predicting welfare policy attitudes. Lower income respondents residing in neighborhoods with higher household public assistance use are more likely to endorse positive attitudes toward welfare than their higher income neighbors. Given the exploratory nature of this study, the author concludes with implications for such findings and proposes future research.
New growth regimes, but still institutional diversity

Whereas the American case may hint that product and labour market deregulation, venture capital and NASDAQ are necessary for the success of a technological led growth, the international comparison suggests the coexistence of at least three successful configurations. Deregulated economies explore a science pushed innovation, along with external labour flexibility, significant inequality in terms of competences. But social democratic countries develop a cooperative approach to the knowledge based economy: rather homogenous educational level, life long learning, negotiation by social partners of the consequence of innovation, collectively organized labour mobility. There is a third configuration for some catching-up economies that use information technology as a method for leapfrogging: labour markets remain largely institutionalised and regulated, without exerting adverse impact upon macroeconomic performance.
Redistribution to Rent Seekers, Foreign Aid and Economic Growth

This paper analyzes the consequences of redistribution of public funds to rent seekers. Therefore, it introduces redistribution to rent seeking agents into Barro's (1990) endogenous growth model with a productive public sector. It shows that the growth rate decreases in the share of the public funds that is redistributed. The public sector's relative sizes that maximize growth and welfare become also smaller in presence of redistribution. Further, if foreign aid is added to the model, the relationship between aid and growth turns out to be inverted-U shaped under reasonable policy assumptions, which is consistent with the finding of an Aid Laffer Curve by some recent empirical studies
Shared Beliefs and Imposed Interdependencies as Determinants of Ally Networks in Overlapping Subsystems

We add the concept of imposed interdependencies to components of the Advocacy Coalition Framework to derive four hypotheses regarding coordinated behavior in overlapping geographic and functional policy subsystems. More specifically, we address: (1) whether imposed interdependencies affect the extent to which shared beliefs are related to coordinated behavior; and (2) which types of beliefs are the principal `glue' of coordination. We then examine the implications of these hypotheses in an empirical analysis of ally networks in San Francisco Bay-Delta water policy. Our empirical results suggest that both belief congruence and functional interdependence are important for understanding coordination. Further, the types of beliefs critical to coordination are consistent with the underlying rationale - but not necessarily the specific hypotheses - of the Advocacy Coalition Framework.
ISO 9000 certification and quality management in Spain: results of a national survey

The increasing demand of mechanisms making easier the choice of a provider, both in the domestic and global markets, has contributed to ISO 9000 certification possession becoming a requisite for the development of commercial relations. The present article is based upon the results of an empirical research in which the effectiveness and reach of ISO 9000 certification is studied at a multi‐sector level in Spain. Mail surveys were carried out on 3,864 certificated organizations, and 749 (19.4 per cent) responded. Results indicated that certification helps in terms of being a management tool, a source of competitive advantages and its potential to stimulate the company transition towards total quality management.
The Selection of Policies for Ballot Initiatives: What Voters Can Learn from Legislative Inaction

This paper models the process through which proposals are placed on the ballot as initiatives. Importantly, proposals that reach the ballot were not enacted by the legislature. We show that this fact has important consequences for the type of policy proposals that reach the ballot: as the legislature would enact any proposal that increases everyone's utility (in expectation), proposals that reach the ballot must be bad for some segment of the population. We partition the population into voters who would benefit from a group's proposal and those who would not and show that voters can use the legislature's inaction to obtain a better estimate of the initiative's expected value. In particular, we show that voters that are not in the sponsoring group infer that proposals that become initiatives have negative expected value and that the expected value of an initiative is decreasing in the size of the group that sponsors it.
Therapeutic Management of Cerebral Arteriovenous Malformations. Present Role of Interventional Neuroradiology

This chapter summarizes the authors' experience in the endovascular therapy of cerebral arteriovenous malformations (AVMs). This clinical series includes 660 patients treated from 1980 to 2005. The first 148 patients were treated at University Hospital, in London, Ontario Canada, in association with Drs. Allan Fox, Dave Pelz, John Girvin and Charles Drake. The next 512 patients were treated at UCLA Medical Center, Los Angeles, California in association with Drs. Gary Duckwiler, Reza Jahan, Jacques Dion, Pierre Gobin, Neil Martin and John Frazee. Only patients treated with superselective endovascular/intraoperative catheterization and embolization of avm arterial feeders were included. Cerebral arteriovenous malformations treated by non-selective injection of beads in ICA or vertebral arteries were excluded. Modern neuroimaging modalities associated to the anatomical, topographic and functional evaluations of cerebral avms such as brain CT and CTA, MRI, MRA and functional MRI are all utilized at UCLA Medical Center. They have become essential in the therapeutic management of avms closely related to cerebral eloquent areas (figure 1).
An attention based model for off-topic spontaneous spoken response detection: An Initial Study

Automatic spoken language assessment systems are gaining popularity due to the rising demand for English second language learning. Current systems primarily assess fluency and pronunciation, rather than semantic content and relevance of a candidate's response to a prompt. However, to increase reliability and robustness, relevance assessment and off-topic response detection are desirable, particularly for spontaneous spoken responses to open-ended prompts. Previously proposed approaches usually require prompt-response pairs for all prompts. This limits flexibility as example responses are required whenever a new test prompt is introduced. This paper presents a initial study of an attention based neural model which assesses the relevance of prompt-response pairs without the need to see them in training. This model uses a bidirectional Recurrent Neural Network (BiRNN) embedding of the prompt to compute attention over the hidden states of a BiRNN embedding of the response. The resulting fixed-length embedding is fed into a binary classifier to predict relevance of the response. Due to a lack of off-topic responses, negative examples for both training and evaluation are created by randomly shuffling prompts and responses. On spontaneous spoken data this system is able to assess relevance to both seen and unseen prompts.
Mortality of Smoking by Gender

Exposure to cigarette smoke has had and will continue to have a huge effect on mortality. Significant differences in smoking prevalence rates by gender have contributed to varying levels and rates of improvement in mortality over the last several decades and are expected to continue to influence mortality improvement differently over the next several decades. The combined effect of greater historical smoking prevalence rates by males and their corresponding earlier and larger reduction has in part been responsible for the recent improvement in mortality rates for males compared to that for females in the United States. Similar patterns are evident in almost all economically developed countries, although their timing and levels differ. The patterns in less-developed countries will likely follow similar patterns as concerns emerge about the effect of smoking on the mortality of their citizens. The objective of this article is to compare smoking prevalence and cessation by gender and the effect on smoking-attributable and, in turn, all-cause mortality. A summary of mortality attribution approaches used to enhance the evaluation of the effect of smoking and projections of mortality rates by gender is also provided.
Understanding the canine intestinal microbiota and its modification by pro‐, pre‐ and synbiotics – what is the evidence?

Abstract Interest in the composition of the intestinal microbiota and possibilities of its therapeutic modifications has soared over the last decade and more detailed knowledge specific to the canine microbiota at different mucosal sites including the gut is available. Probiotics, prebiotics or their combination (synbiotics) are a way of modifying the intestinal microbiota and exert effects on the host immune response. Probiotics are proposed to exert their beneficial effects through various pathways, for example production of antimicrobial peptides, enhancing growth of favourable endogenous microorganisms, competition for epithelial colonisation sites and immune‐modulatory functions. Despite widespread use of pro‐, pre‐ and synbiotics, scientific evidence of their beneficial effects in different conditions of the dog is scarce. Specific effects of different strains, their combination or their potential side‐effects have not been evaluated sufficiently. In some instances, in vitro results have been promising, but could not be transferred consistently into in vivo situations. Specific canine gastrointestinal (GI) diseases or conditions where probiotics would be beneficial, their most appropriate dosage and application have not been assessed extensively. This review summarises the current knowledge of the intestinal microbiome composition in the dog and evaluates the evidence for probiotic use in canine GI diseases to date. It wishes to provide veterinarians with evidence‐based information on when and why these products could be useful in preventing or treating canine GI conditions. It also outlines knowledge about safety and approval of commercial probiotic products, and the potential use of faecal microbial transplantation, as they are related to the topic of probiotic usage.
Is interpersonal trust a necessary condition for organisational learning?

Abstract The organisational behaviour and management literature has devoted a lot attention on various factors affecting organisational learning. While there has been much work done to examine trust in promoting organisational learning, there is a lack of consensus on the specific type of trust involved. The purpose of this paper is to highlight the importance of interpersonal trust in promoting organisational learning and propose a research agenda to test the extent of interpersonal trust on organisational learning. This paper contributes to the existing organisational learning literature by specifying a specific form of trust, interpersonal trust, which promotes organisational learning and proposing a future research direction. The paper is organised as follows: firstly, a common conceptualisation of organisational learning is revisited. Secondly, the existing literature on trust reviewed and salient points on how interpersonal trust enhances organisational learning discussed. Finally, a research agenda to test the extent of interpersonal trust on organisational learning is being set out.

Gender and corruption: testing the new consensus

The search for a sustainable anti-corruption strategy has seen a number of reform ideas introduced into the public sector of many African countries, by the development community. These reforms have met with modest results, at best, as evidenced by the fact that current data suggest entrenched corruption in many African countries. Failure of previous anti-corruption strategies leads to the promotion of women in the public sector as a potential anti-corruption remedy. This nascent idea is premised on presumptions that women are more ethical than men. However, failure of previous anti-corruption strategies begs legitimate questions: would women prove less corrupt when exposed to environments characterised by corrupt opportunities and networks? Would women maintain high ethical standards in the public realm when social obligations require certain acts of corruption? This article uses primary data from Ghana to address these questions. The article concludes that women may not prove less corrupt in the public sector if corrupt opportunities and networks are not restrained. Also, the very gender system, which is used to justify women's proclivity to less corrupt behaviour and subsequent integration into the public sector, could itself be the source of corruption as women attempt to fulfil their gender roles.

Synchronization of Work Schedules

Why do people work intermittently and why do they synchronize their work schedules? A group of interacting workers who differ in tastes is analyzed. A lifetime labor supply model is developed which combines tiring, rhythmic changes in the environment, and interactions among workers arising from communication and coordination. A multiplicity of synchronized equilibria arises. These equilibria can be ranked according to the length of the work period. Equilibria with longer hours are preferred by all workers in the group. The worker with the highest aversion to work sets the standard and others conform to him.

Financial integration and international transmission of business cycles: evidence from dynamic correlations

We estimate determinants of dynamic correlations of output comovement of OECD countries between 1990 and 2008. We show that trade intensity, degree of financial integration and specialization pattern have significantly different effects on comovements at different frequencies. This can bias the results using aggregate data or statistical filters. For example, financial integration is showed to have the highest positive effect for middle business frequencies, while it is insignificant for short-term frequencies.
Noncoherent Amplitude/Phase Modulated Transmission Schemes for Rayleigh Block Fading Channels

In this paper, we investigate noncoherent transmission schemes using amplitude/phase modulation. For uncoded transmission schemes, we derive the pairwise error probability (PEP) and its high-SNR approximation for signal vectors with unequal power values using a noncoherent maximum-likelihood detector under Rayleigh block fading channels. For coded transmission schemes, we consider differential amplitude/phase modulated signals and introduce a codeword-interleaving strategy to improve the error performance. The design criteria for the signal labelling and bit interleaving are also derived via the high-SNR approximation of the PEP. At the receiver, we devise an iterative channel amplitude estimator to enhance the detection reliability. With the help of a specially-designed iterative receiving algorithm, the designed noncoherent coded scheme can provide a significant improvement, either in the error-floor or the waterfall region.
