On the Outside, Looking in : Understanding Transparency at the Frontline

This doctoral dissertation examines the effects of transparency on the daily work of street-level bureaucrats and their interactions with citizens. By studying food and product safety inspectors, this dissertation shows that transparency helps street-level bureaucrats do their job. By studying citizens’ perceptions of multiple enforcing street-level bureaucrats (e.g. parking wardens), this dissertation reveals that citizens are biased about the street-level bureaucrats they meet, but this does not mean they will make what street-level bureaucrats do transparent to others

Engineering vascularised tissues in vitro

Tissue engineering aims at replacing or regenerating tissues lost due to diseases or traumas (Langer and Vacanti, 1993). However, mimicking in vitro the physiological complexity of vascularized tissue is a major obstacle, which possibly contributes to impaired healing in vivo. In higher organisms, native features including the vascular network, the lymphatic networks and interstitial flow promote both mass transport and organ development. Attempts to mimic those features in engineered tissues will lead to more clinically relevant cell-based therapies. Aside from current strategies promoting angiogenesis from the host, an alternative concept termed prevascularization is emerging. It aims at creating a biological vasculature inside an engineered tissue prior to implantation. This vasculature can rapidly anastamose with the host and enhances tissue survival and differentiation. Interestingly, growing evidence supports a role of the vasculature in regulating pattern formation and tissue differentiation. Thus, prevascularized tissues also benefit from an intrinsic contribution of their vascular system to their development. From those early attempts are emerging a body of principles and strategies to grow and maintain, in vitro, those self-assembled biological vascular networks. This could lead to the generation of engineered tissues of more physiologically relevant complexity and improved regenerative potential

The (un)intended effects of street-level bureaucrats' enforcement style: Do citizens shame or obey bureaucrats?

This study studies the intended and unintended effects of street-level bureaucrats' enforcement style. More specifically, it answers to what extent street-level bureaucrats' enforcement style affects citizens' obedience (i.e. intended effect) during face-to-face encounters and willingness to publicly shame bureaucrats (i.e. unintended effect). Building on insights from street-level enforcement and the theory of social interactionist theory of coercive actions, a trade-off is theorized between the effect of enforcement style on citizens' on-the-spot obedience and on public shaming. Results of an experiment (n = 318) and replication (n = 311) in The Netherlands reveal that (1) neither the legal nor facilitation dimension has an effect on on-the-spot obedience; (2) the legal dimension does not affect public shaming but; (3) the facilitation decreases it. These findings are robust across both the experiment and replication

Street-level Enforcement Style: A Multidimensional Measurement Instrument

This study investigates street-level bureaucrats’ enforcement style and its underlying dimensions by developing and validating a multidimensional measurement scale. Developing a measurement scale for enforcement style is relevant because the number of underlying dimensions is contested and studies developing measurement scales are scarce. This complicates cross-sector and cross-national comparisons. Using a survey among inspectors of the Netherlands Food and Consumer Product Safety Authority, street-level enforce

Does Disclosure of Performance Information Influence Street-level Bureaucrats' Enforcement Style?

Governments use different regulatory instruments to ensure that businesses owners or "inspectees" comply with rules and regulations. One tool that is increasingly applied is disclosing inspectees' performance information to other stakeholders. Disclosing performance information has consequences for street-level bureaucrats because it increases the visibility of their day-to-day work. Using a survey (n =507) among Dutch inspectors of the Netherlands Food and Consumer Product Safety Authority, this article shows that the disclosure of performance information has an impact on enforcement style at the street level. Findings show that perceived disclosed performance information positively enhances all three dimensions of street-level bureaucrats' enforcement style (legal, facilitation, and accommodation). This effect is strongest for facilitation and accommodation and weakest for the legal style. Perceived resistance by inspectees partly explains this effect. Contrary to expectations, more perceived disclosure does not result in more but in less perceived resistance of inspectees by street-level bureaucrats

Why Do Employers (Fail to) Hire People with Disabilities? : A Systematic Review of Capabilities, Opportunities and Motivations.

Purpose To increase the number of people with disabilities in employment, we need to understand what influences employers’ hiring decisions. In this systematic review, we map out factors affecting employers’ hiring decisions about people with disabilities. Methods This study is a systematic review that applies the COM-B model to identify factors that contribute to employers (not) hiring people with disabilities. The COM-B model proposes that employers will perform hiring behavior (B) if they have the capability (C), opportunity (O) and motivation (M) to do so. We also investigate if factors have a negative, positive or no effect. We report in accordance with the PRISMA guidelines. Results In a review of 47 studies, we find 32 factors. Most of these factors are barriers. The most frequently mentioned barriers are employers’ (1) expectations that people with disabilities are unproductive, (2) expectations that people with disabilities cost a lot of money, and employers’ (3) lack of knowledge about disabilities. The most researched facilitators for employers to hire people with disabilities include (1) the motivation to help others, (2) working in a large organization, and (3) expecting a competitive advantage. The effect of factors can differ depending on contextual circumstances, including the type of organization, the type of disability and different policies. Conclusions We conclude that hiring decisions are influenced by an array of different barriers and facilitators. The effect of these factors can differ across organizations and disability types. Our study of factors affecting hiring can be used by scholars, policy makers, and organizations to create interventions to increase the hiring of people with disabilities

Leading frontline enforcers: How supervisors’ leadership style impacts inspectors’ enforcement style

This article analyzes the relation between leadership style of managers and the enforcement style of street-level bureaucrats. We also studied the influence of organizational culture. The analysis is based on a survey among 549 inspectors of the Food and Consumer Product Safety Authority (NVWA) in The Netherlands. Studying transactional leadership and servant leadership the findings show that contrary to the general assumptions in leadership literature the influence of leadership style on enforcement behaviour of inspectors is only very limited. Organization culture has more influence on how inspectors enforce rules in their interactions with inspectees

Blaming the bureaucrat: does perceived blame risk influence inspectors’ enforcement style?

Is there a relation between street-level bureaucrats’ enforcement style and their perception of the risk of getting blamed? This article answers this question on the basis of a survey (n = 507) among inspectors of the Netherlands Food and Product Safety Authority. We included perceived media attention on their work as a factor that might influence street-level bureaucrats’ perception of blame risk and their enforcement style. Three dimensions of enforcement style were distinguished from earlier research: legal, facilitative and accommodative. We found that when inspectors perceive more blame risk, they employ a slightly less legal style and, instead, employ a more accommodative style. Thus, they act a little less formally and less coercively (i.e. legal) and take greater account of their peers’ opinions (i.e. accommodative). However, perceived media attention did not have a significant influence on enforcement style. Points for practitioners: 1. When inspectors perceive more blame risk, they tend to pay more attention to the opinion of peers (other inspectors, supervisors, etc.). 2. Blame risk does not lead to the use of a more formal inspection style. 3. Media attention does not play an important role in enhancing the blame risk perception of inspectors. 4. This media and blame risk is less important than often found in the case of politicians. This may be connected to the fact that the work of inspectors as street-level bureaucrats is less visible to the wider public (and the media)

Deformations of calibrated D-branes in flux generalized complex manifolds

We study massless deformations of generalized calibrated cycles, which describe, in the language of generalized complex geometry, supersymmetric D-branes in N=1 supersymmetric compactifications with fluxes. We find that the deformations are classified by the first cohomology group of a Lie algebroid canonically associated to the generalized calibrated cycle, seen as a generalized complex submanifold with respect to the integrable generalized complex structure of the bulk. We provide examples in the SU(3) structure case and in a `genuine' generalized complex structure case. We discuss cases of lifting of massless modes due to world-volume fluxes, background fluxes and a generalized complex structure that changes type.Comment: 52 pages, added references, added comment on ellipticity in appendix B, made minor changes according to instructions referee JHE
