The creative knowledge city in Europe: Structural conditions and urban policy strategies for competitive cities

Results of a new large-scale study question the role of creative talents in fostering economic prospects. It is shown that in Europe, with its cultural diversity and long urban history, Florida’s concepts have to be used with caution. The new study suggests that in Europe, along with so-called ‘hard’ and ‘soft’ factors, there is a third crucial group of factors, related to personal networks, which impacts on economic perspectives. These networks include personal links, professional and social relations and other types of local social connections related to people’s life courses. This appeared to be strong and consistent outcomes of a survey among employees and interviews with employers, managers and trans-national migrants, conducted simultaneously in 13 European cities. It was also made clear that so-called hard conditions, especially job availability, were the second most important factor. Incidentally soft conditions were relevant, but never of prime importance. ‘Soft’ factors such as diversity, openness, amenities, and tolerance were hardly mentioned as relevant deciding factors for settling in a specific city. It also became clear that contemporary conditions that make some European cities more attractive than others for these industries offer only a partial explanation. The current fashionable focus on fostering ‘creative talents’ to improve economic prospects is not an option for all European cities. An alternative view on urban policies, associated with concepts that seem to be crucial for Europe, has been suggested.
Building a better workplace for teen volunteers through inclusive behaviors

Facing a decline in the number of hours donated to nonprofit organizations, volunteer coordinators must strive to determine the most effective strategies for retaining volunteers. Relationship management theory provides a framework to gauge the well-being of an organization's relationship with its stakeholders. Through surveys administered to 317 teenage volunteers at three library systems, this study found that of four factors—trust, commitment, satisfaction, and control mutuality—trust had the strongest ability to predict intent to continue volunteering. Further analysis revealed that trust could be enhanced by including teenagers in work groups throughout the organization, seeking their input on organizational decisions, and ensuring they receive formal and informal organizational communications.
Poverty and informal economy participation

This paper uses a household survey of the Romanian informal economy to analyse the effects of poverty on informal economy participation. We begin by developing a simple theoretical model, which shows that the participation is driven by low income and the gap between desired and actual income level. We then estimate the determinants of households' participation in the informal economy. Empirical findings are consistent with the theoretical prediction. In addition, a positive association between husbands and wives working in the informal economy implies the deep poverty faced by a family whose head participates in the informal economy.

That My Neighbor’s Cow Might Live: Effectuation, Entrepreneurship Education, and Economic Development in Croatia

It is widely recognized that entrepreneurship is vital to regional economic development. And recent studies in entrepreneurial expertise have shown that effectuation is important to doing entrepreneurship well. Furthermore, since expertise involves teachable and learnable aspects of a knowledge domain, it is reasonable to assume that entrepreneurship education would have a significant role to play in regional economic development. In this paper, we empirically investigate the above argument in two stages: First, we explore the role of effectuation in designing a competitive graduate program for entrepreneurship in Croatia; then, we examine the role of entrepreneurship education in regional economic development.
Studying Trust in Virtual Organizations

The core objective of this article is to introduce the repertory grid technique as a powerful methodology into research on trust in virtual organizations. This technique is particularly capable of yielding insights into the subjective meaning of trust. Virtual organizations have been chosen as our empirical field because the literature shows a broad consensus that trust is one of the most important success factors for the initiation, development, and continuation of activities in these types of hybrid regimes. On the basis of a discussion of the literature on trust in networks and virtual organizations, we present our empirical case study of two Swiss virtual organizations. It reveals that the emergence of trust in virtual organizations depends strongly on personal bonds and shared experiences in the practical realization of projects, whereas generalized rules and contracts play only a supplementary role. Localized and experience-based commitments as well as the proactive behavior of the partners involved are identified as decisive denominators of trust.
Phylogeography of Semiterrestrial Isopod, Tylos granuliferus, on East Asian Coasts

We conducted phylogenetic analyses using mitochondrial COI gene sequences of Tylos granuliferus, a semiterrestrial coastal isopod in East Asia, to clarify possible phylogeographic patterns and to assess relationships between present and past marine environments and genetic population structures. Our results strongly suggest the presence of four clades of T. granuliferus, one of which consists of three subclades. The distribution pattern of clades and subclades seems to have been affected by ocean current activities. Our results also suggest that historical changes in oceanic environments and the subsequence bifurcation of current streamlines affected the first and second divergences of T. granuliferus during the late Miocene and near the beginning of the Pliocene, respectively.
COMMON PERSISTENCE IN CONDITIONAL VARIANCES

A common finding in many of the recent empirical studies with the ARCH class of models applied to high frequency financial data concerns the apparent persistence of shocks for forecast of the future conditional variances. It is likely that several different variables share this same implied long-run component, however. In that situation, the variables are defined to be copersistent in variance. Conditions for copersistence to occur in the linear multivariate GARCH model are presented. These conditions parallel the conditions for linear cointegration in the mean. A simple empirical example with foreign exchange rate data illustrates the ideas. Copyright 1993 by The Econometric Society.
When Brokers May Not Work: The Cultural Contingency of Social Capital in Chinese High-tech Firms

In this paper, we bring structural holes theory to different cultural contexts by studying the effect of structural holes in four high-tech companies in China and assessing whether they confer the benefits to individuals occupying the brokering position in a career network that have been found in Western contexts. On the level of national culture, we propose that the typical collectivistic culture of China will dampen the effects of structural holes. On the organizational level, we propose that in organizations that foster a high-commitment culture—a culture that emphasizes mutual investment between people—the control benefits of structural holes are dissonant with the dominant spirit of cooperation, and the information benefits of structural holes cannot materialize due to the communal-sharing values in such organizations. Empirical results of network surveys confirm our hypotheses, and interview data add depth to our explanations. Brokers do not fit with the collectivistic values of China. Further, the more an organization possesses a clan-like, high-commitment culture, the more detrimental are structural holes for employees' career achievements such as salary or bonus, even after controlling for a host of other factors that may influence these career outcomes. In high commitment organizations, the “integrators” who bring people together to fill structural holes enjoy greater career benefits.
Endowments, Output, and the Bias of Directed Innovation

In this paper, I ask the question: Does the output-mix of countries change in response to changes in factor endowments? If so: How long does it take? Using data on capital, as well as skilled and unskilled labour employed in three-digit International Standard Industrial Classification (ISIC) manufacturing industries for a sample of 27 developing and developed countries over the 1973--1990 period, I find that the output-mix of countries does not change in response to endowment changes, even after 15 years. This answer raises another question: How then do countries absorb changes in factor endowments? The data show that in both the short and long runs, an increase in the supply of a production factor reduces its rate of return and makes it more intensively used in all sectors of the economy: changes in production techniques. In the long run, the point estimate is that the reduction in the rate of return is more than 50% larger than in the short run. This is consistent with induced innovations being predominantly biased towards the scarce factor. Copyright , Wiley-Blackwell.
Kids or courses? Gender differences in the effects of active labor market policies

We investigate active labor market programs in Austria. We find only small effects, if any, for most of the programs. However, the programs may have unintended consequences for women. In particular for younger women, a key effect of the programs and one reason for the male–female effect differential that is observed in the literature is to reduce or postpone pregnancies and to increase their attachment to the labor force. Furthermore, the variables capturing pregnancies and times of parental leave play a key role in removing selection bias.
Completing the industrial ecology cascade chain in the case of a paper industry – SME potential in industrial ecology

The concept of industrial ecology (IE) adopts the ecosystem principle of roundput in human industrial systems as the emphasis is on the utilization of wastes between different industrial actors. IE faces new challenges, as the emission and waste structures of the industrial world are continuously changing and the importance of the latter steps of the industrial material flows, i.e. the ‘consumption emissions’, is increasing. There is also a lack of waste processors and handlers in these latter steps. This paper considers the IE thesis by focusing on the cascade chain of the paper industry. It is suggested here that SMEs can serve as potential participants in industrial ecosystems, for example as waste processors and waste handlers.

Earnings Announcements and the Components of the Bid-Ask Spread

This study investigates the behavior of the components of the bid-ask spread around earnings announcements. The authors find that the adverse selection cost component significantly increases surrounding the announcements, while the inventory holding and order processing components significantly decline during the same periods. Their results suggest that the directional change in the total bid-ask spread depends on the relative magnitudes of the changes in these three components. Specifically, the decreases in inventory holding costs and order processing costs imply that earnings announcements may have an insignificant impact on the total bid-ask spread, even when they result in increased information asymmetry.

Ethics in leadership: The case of local politicians

Abstract The mainstream literature on leadership has little to say about the role of ethics. Equally, much of this literature is concerned with the private sector and with managerial leadership. This paper addresses both these gaps, by reporting on the development of a scale for measuring ethical values in local political leadership, the public service values scale. This is one section of a larger instrument for assessing the skills of local political leaders: the Warwick Political Leadership Questionnaire. The paper reports on the use of this instrument in a 360 degree format, following piloting of a self assessment version. The responses of 19 elected members and 241 feedback givers are analysed. These data offer support for the validity and reliability of the public service values scale. The paper concludes with a research agenda, offering suggestions for how this scale can be applied to researching ethics in leadership.
Identifying patterns of item missing survey data using latent groups: an observational study

Objectives To examine whether respondents to a survey of health and physical activity and potential determinants could be grouped according to the questions they missed, known as ‘item missing’. Design Observational study of longitudinal data. Setting Residents of Brisbane, Australia. Participants 6901 people aged 40–65 years in 2007. Materials and methods We used a latent class model with a mixture of multinomial distributions and chose the number of classes using the Bayesian information criterion. We used logistic regression to examine if participants’ characteristics were associated with their modal latent class. We used logistic regression to examine whether the amount of item missing in a survey predicted wave missing in the following survey. Results Four per cent of participants missed almost one-fifth of the questions, and this group missed more questions in the middle of the survey. Eighty-three per cent of participants completed almost every question, but had a relatively high missing probability for a question on sleep time, a question which had an inconsistent presentation compared with the rest of the survey. Participants who completed almost every question were generally younger and more educated. Participants who completed more questions were less likely to miss the next longitudinal wave. Conclusions Examining patterns in item missing data has improved our understanding of how missing data were generated and has informed future survey design to help reduce missing data.
Trace Metals Concentrations at the Atmosphere Particulate Matters in the Southeast Asian Mega City (Dhaka, Bangladesh)

Atmospheric particulate matters were collected on quartz fibre filters for 24 hours with a low volume sampler from January 2014 to March 2014 at the Southeast Asian mega city (Dhaka, Bang- ladesh). Particulate matters samples were analysed for eleven trace metals with inductively cou- pled plasma mass spectrometer (ICP-MS) at Ca Foscari University of Venice, Italy. Trace metals were extracted from filters with digestion method using a mixture of HNO3 and H2O2. The average concentration of the determined trace metals of As, Cd, Ni, Cu, Pb, Cr, Fe, Mn, Zn, Sband Se were 3.06, 6.28, 3.77, 11.98, 305.6, 9.2, 2057.0, 42.2, 303.3, 5.47 and 2.43 ng∙m −3 , respectively. Arsenic concentration is much lower in the atmosphere of Dhaka, though Bangladesh has severe arsenic problem in the ground water. Lead and cadmium concentrations showed decreasing trend in Dhaka compared than previous measurements—but still they have very high levels compared than Europe and USA. There is very limited information for Mn, Sb and Se concentrations in Dhaka air. Correlation studies showed that several trace metals had potential joint sources of origin, e.g., manganese is highly correlated with iron (r 2 = 0.97) and nickel (r 2 = 0.84), copper (r 2 = 0.86); lead with arsenic (r 2 = 0.79) and antimony (r 2 = 0.78). Enrichment factors analysis was also done with the data base for the respective metals in earth crust and coal fly ash. As and Cu both have com- bined sources, whereas Cd, Pb and Zn were from coal fly ash.Trace metals concentrations in Dhaka city air were much higher than Europe and USA but comparable or slightly lower than other south Asian countries. This is the first extensive study for the eleven trace metals with ICP-MS in Dhaka, * Corresponding author.
Pharmacodynamic Effects of Canagliflozin, a Sodium Glucose Co-Transporter 2 Inhibitor, from a Randomized Study in Patients with Type 2 Diabetes

Introduction This randomized, double-blind, placebo-controlled, single and multiple ascending-dose study evaluated the pharmacodynamic effects and safety/tolerability of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in patients with type 2 diabetes. Methods Patients (N = 116) discontinued their antihyperglycemic medications 2 weeks before randomization. Patients received canagliflozin 30, 100, 200, or 400 mg once daily or 300 mg twice daily, or placebo at 2 study centers in the United States and Germany, or canagliflozin 30 mg once daily or placebo at 1 study center in Korea, while maintaining an isocaloric diet for 2 weeks. On Days –1, 1, and 16, urinary glucose excretion (UGE), plasma glucose (PG), fasting PG (FPG), and insulin were measured. The renal threshold for glucose (RTG) was calculated from UGE, PG, and estimated glomerular filtration rate. Safety was evaluated based on adverse event (AE) reports, vital signs, electrocardiograms, clinical laboratory tests, and physical examinations. Results Canagliflozin increased UGE dose-dependently (∼80–120 g/day with canagliflozin ≥100 mg), with increases maintained over the 14-day dosing period with each dose. Canagliflozin dose-dependently decreased RTG, with maximal reductions to ∼4–5 mM (72–90 mg/dL). Canagliflozin also reduced FPG and 24-hour mean PG; glucose reductions were seen on Day 1 and maintained over 2 weeks. Plasma insulin reductions with canagliflozin were consistent with observed PG reductions. Canagliflozin also reduced body weight. AEs were transient, mild to moderate in intensity, and balanced across groups; 1 canagliflozin-treated female reported an episode of vaginal candidiasis. Canagliflozin did not cause hypoglycemia, consistent with the RTG values remaining above the hypoglycemia threshold. At Day 16, there were no clinically meaningful changes in urine volume, urine electrolyte excretion, renal function, or routine laboratory test values. Conclusions Canagliflozin increased UGE and decreased RTG, leading to reductions in PG, insulin, and body weight, and was generally well tolerated in patients with type 2 diabetes.

Temporal relationships of hepatitis C virus RNA and antibody responses following experimental infection of chimpanzees

Liver enzyme levels, viral RNA, and the immune response against both structural and nonstructural hepatitis C virus (HCV) proteins have been studied in experimentally infected chimpanzees in order to further understand the natural history of HCV infection. An ELISA for measuring both IgG and IgM responses to core (c22), 33c (NS3), and c l00. (NS4) was employed. The IgG response rates were 5/8 for core, and 8/8 for both 33c and c100. Utilizing this antigen combination, a t least one antibody response is measurable at, or within 3 weeks of, the major ALT peak. Although no individual antibody response is universally associated with initial detection of seroconversion, the combination of all three recombinant proteins measures seroconversion an average of 54 days earlier than with c100 alone, in 6/8 of the animals. IgM responses were measurable in 5/8 of the chimpanzees, were of shorter duration, and usually arose concomitantly with IgG responses. IgM appears to be a good indicator of primary infection since neither boosting nor recrudescence of disease during the chronic phase of disease elicited a secondary IgM response. Viral RNA can be measured 4‐7 days (average = 9 days) postinfection with the period preceding the ALT peak being characterized by several PCR positive segments interrupted by periods in which no viral RNA can be measured. Following the ALT peak, chronically infected animals with recurring ALT elevations are generally PCR positive with intercedent PCR negative periods. Those animals that appear to have biochemically resolved disease generally have PCR negative profiles, although they still may periodically exhibit PCR positive sera. This indicates that with the recent advent of new screening techniques, a more stringent definition of HCV resolution will be required.
The Structure and Management of Alliances: Syndication in the Venture Capital Industry

Syndicates are a form of inter-firm alliance in which two or more venture capital firms co-invest in an investee firm and share a joint pay-off. Syndication is a significant part of the venture capital market yet little research has been conducted into the process of structuring syndicate deals and the management of syndicates following deal completion. This paper analyses the neglected issues concerning the structuring and management of syndicated venture capital investments from the perspectives of both lead and non-lead syndicate members using two surveys of venture capital firms and examination of syndication documents. Lead investors typically have larger equity stakes and the syndicated investment agreement is a document that enshrines the rights of participants rather than specifying behaviour. Contractual arrangements typically serve as a back drop to relationships as non-legal sanctions are important and decisions are typically reached following discussion and consensus, but lead venture capital investors' residual and specific powers are important in ensuring timely decision-making. The findings extend previous work on alliances by emphasizing the importance of non-legal sanctions, especially reputation effects, in mitigating opportunistic behaviour by dominant equity holders. The paper also adds to the limited research on the dynamics of alliances by highlighting the role of repeat syndicates. Copyright 2003 Blackwell Publishing Ltd.
Determinants of Dividend Policy: The Case of Kuwait

Ever since the work of John Lintner (1956), followed by the work of Miller and Modigliani (1961), dividend policy remains a controversial issue. Some of the questions that remain unanswered include: Does dividend policy affect value? What are the factors that determine dividend policy? Is dividend policy determined dependently or independently? A comprehensive survey project on dividend policy in Kuwait was conducted and two papers were produced. The first paper focused on the relationship of dividend policy to investment and financing policies, see Al‐ Deehani and Al‐Loughani (2002). This paper is a part of that project. It presents empirical effort to the area of dividend policy determinants in Kuwait as an emerging market. Based upon a result of a questionnaire survey, the paper will highlight (1) top management’s perception of value‐relevant and value‐irrelevant determinants of dividend policy, and (2) determine whether managers in different industries share similar views about these determinants. The paper is organized in the following manner: first the determinants of dividend policy are discussed through a review of the relevant literature. This is followed by the research methods stating the issues of concern to this study. The remainder of the paper discusses the results through the analysis of managers’ perceptions of determinants and a cross‐sectional analysis. The paper ends with a summary and the conclusions drawn from the study.
