Personnel constraints in public organizations: a study of intraorganizational variation and performance
Prior research has shown that personnel constraints are far more prevalent in the public sector than in the private sector. Anecdotal accounts suggest that public managers are hamstrung by these personnel constraints – particularly their inability to reward and punish employees to promote higher performance. As a result, more than three decades of public management reform has attempted to loosen these constraints on the assumption that more personnel system flexibility will lead to increased organizational performance. We mount an empirical study to test this assumption with data taken from a large-scale survey of English local authorities and other sources. We operationalize personnel constraints using Rainey’s (1979; Rainey et al. 1976) longstanding measures: "difficulty in removing poor managers" and "difficulty in rewarding good managers". We show that attitudes towards personnel constraint vary within organizations in statistically significant ways. The results from our lagged autoregressive multiple regression models also show that one of our personnel constraint measures – "difficulty in removing poor managers" – is harmful to performance but that the other "difficulty in rewarding good managers" has weak but positive short-term effects. The implications of these findings for public management research and practice are considered in the concluding section of the paper.postprintThe 10th Biennial Public Management Research Conference, Ohio State University, Columbus, OH., 1-3 October 2009
What You See Depends on Where You Sit: Managerial Perceptions of Red Tape in English Local Government
This exploratory study investigates red tape in English local government. We build on previous research by examining perceptions of internal and external measures of red tape among three tiers of public managers: corporate officers (includes the chief executive officer and corporate policy directors), chief officers (the most senior officers with specific service delivery responsibilities), and service managers (first-line supervisory officers and section heads). The results show that these officials perceive red tape differently depending on their respective roles and stations in local government and that the determinants of red tape are likely to vary at each tier. Where there is common ground it suggests that a developmental culture, logical incremental strategy formulation, reductions in regulation and stable external political contexts will work to reduce red tape. The implications for theory and practice are discussed.postprin
Bureaucratic malaises and their remedies in Public and Nonprofit Organizations
Many experts have observed that bureaucratic malaises are endemic in public sector organizations. These so-called “diseases,” which include personnel constraints, red tape and risk avoidance, can discourage workers, damage organizational performance, and lower the quality of public services. The depth and impact of these malaises are tested across the public and nonprofit sectors using data from the third National Administrative Studies Project (NASP III). NASP III surveyed randomly selected managers in public and nonprofit organizations in Georgia and Illinois. Multiple informant data are aggregated to the organizational level resulting 47 public and 64 nonprofit organizations for further analysis. Multivariate statistical analysis suggests that most of the maladies have harmful effects on work quality in the public sector, but not on the nonprofit agencies studied in this sample. The results further show that task clarity does not mitigate the performance effects of these maladies in the public sector whereas in the nonprofit sector it is associated with higher levels of performance. The implications for theory and practice are discussed.postprin
External control and red tape: the mediating effects of client and organizational feedback
Bozeman’s (1993, 2000) external control model of red tape posits that organizations with higher degrees of external control will have higher levels of red tape. According to the model, this is compounded by entropy affecting the communication of rules and their results, limited discretion over rules and procedures, and non-ownership of rules. However, the model predicts that red tape will be mediated by communication from clients and within the organization. Bozeman’s model is often cited in the literature, but it has not been subjected to empirical verification. This study tests the model using data from a multiple informant survey of 136 upper tier English local governments conducted in 2004 and several secondary sources. Statistical results show that external control does indeed lead to higher levels of red tape. We then test a number of organizational feedback mediators and find that client feedback does little to mediate the effects of red tape; the major factor is trust between politicians and officers. We discuss these findings and propose some changes to the model.postprin
The identification of markers for Geoforensic HPLC profiling at close proximity sites
Soil is a highly transferable source of trace physical material that is both persistent in the environment and varied in composition. This inherent variability can provide useful information to determine the geographical origin of a questioned sample or when comparing and excluding samples, since the composition of soil is dependent on geographical factors such as climate, bedrock geology and land use. Previous studies have limited forensic relevance due to the requirement for large sample amounts and unrealistic differences between the land use and geographical location of the sample sites. In addition the philosophical differences between the disciplines of earth sciences, for which most analytical techniques have been designed, and forensic sciences, particularly with regard to sample preparation and data interpretation have not been fully considered. This study presents an enhanced technique for the analysis of organic components of geoforensic samples by improving the sample preparation and data analysis strategies used in previous research into the analysis of soil samples by high performance liquid chromatography (HPLC). This study provides two alternative sets of marker peaks to generate HPLC profiles which allow both easy visual comparison of samples and the correct assignment of 100% of the samples to their location of origin when discriminating between locations of interest in multivariate statistical analyses. This technique thereby offers an independent form of analysis that is complementary to inorganic geoforensic techniques and offers an easily accessible method for discriminating between close proximity forensically relevant locations
Putative β-Barrel Outer Membrane Proteins of the Bovine Digital Dermatitis-Associated Treponemes: Identification, Functional Characterization, and Immunogenicity
Bovine digital dermatitis (BDD), an infectious disease of the bovine foot with a predominant treponemal etiology, is a leading cause of lameness in dairy and beef herds worldwide. BDD is poorly responsive to antimicrobial therapy and exhibits a relapsing clinical course; an effective vaccine is therefore urgently sought. Using a reverse vaccinology approach, the present study surveyed the genomes of the three BDD-associated Treponema phylogroups for putative β-barrel outer membrane proteins and considered their potential as vaccine candidates. Selection criteria included the presence of a signal peptidase I cleavage site, a predicted β-barrel fold, and cross-phylogroup homology. Four candidate genes were overexpressed in Escherichia coli BL21(DE3), refolded, and purified. Consistent with their classification as β-barrel OMPs, circular-dichroism spectroscopy revealed the adoption of a predominantly β-sheet secondary structure. These recombinant proteins, when screened for their ability to adhere to immobilized extracellular matrix (ECM) components, exhibited a diverse range of ligand specificities. All four proteins specifically and dose dependently adhered to bovine fibrinogen. One recombinant protein was identified as a candidate diagnostic antigen (disease specificity, 75%). Finally, when adjuvanted with aluminum hydroxide and administered to BDD-naive calves using a prime-boost vaccination protocol, these proteins were immunogenic, eliciting specific IgG antibodies. In summary, we present the description of four putative treponemal β-barrel OMPs that exhibit the characteristics of multispecific adhesins. The observed interactions with fibrinogen may be critical to host colonization and it is hypothesized that vaccination-induced antibody blockade of these interactions will impede treponemal virulence and thus be of therapeutic value

Inorganic speciation of dissolved elements in seawater: the influence of pH on concentration ratios
Assessments of inorganic elemental speciation in seawater span the past four decades. Experimentation, compilation and critical review of equilibrium data over the past forty years have, in particular, considerably improved our understanding of cation hydrolysis and the complexation of cations by carbonate ions in solution. Through experimental investigations and critical evaluation it is now known that more than forty elements have seawater speciation schemes that are strongly influenced by pH. In the present work, the speciation of the elements in seawater is summarized in a manner that highlights the significance of pH variations. For elements that have pH-dependent species concentration ratios, this work summarizes equilibrium data (S = 35, t = 25°C) that can be used to assess regions of dominance and relative species concentrations. Concentration ratios of complex species are expressed in the form log[A]/[B] = pH - C where brackets denote species concentrations in solution, A and B are species important at higher (A) and lower (B) solution pH, and C is a constant dependent on salinity, temperature and pressure. In the case of equilibria involving complex oxy-anions (MO(x)(OH)(y)) or hydroxy complexes (M(OH)(n)), C is written as pK(n )= -log K(n )or pK(n)* = -log K(n)* respectively, where K(n )and K(n)* are equilibrium constants. For equilibria involving carbonate complexation, the constant C is written as pQ = -log(K(2)(l)K(n )[HCO(3)(-)]) where K(2)(l )is the HCO(3 )(- )dissociation constant, K(n )is a cation complexation constant and [HCO(3)(-)] is approximated as 1.9 × 10(-3 )molar. Equilibrium data expressed in this manner clearly show dominant species transitions, ranges of dominance, and relative concentrations at any pH

Audio Cartography: Visual Encoding of Acoustic Parameters
Our sonic environment is the matter of subject in multiple domains which developed individual means of its description. As a result, it lacks an established visual language through which knowledge can be connected and insights shared. We provide a visual communication framework for the systematic and coherent documentation of sound in large-scale environments. This consists of visual encodings and mappings of acoustic parameters into distinct graphic variables that present plausible solutions for the visualization of sound. These candidate encodings are assembled into an application-independent, multifunctional, and extensible design guide. We apply the guidelines and show example maps that acts as a basis for the exploration of audio cartography
Single-stage repair of adult aortic coarctation and concomitant cardiovascular pathologies: a new alternative surgical approach
BACKGROUND: Coarctation of the aorta in the adulthood is sometimes associated with additional cardiovascular pathologies that require intervention. Ideal approach in such patients is uncertain. Anatomic left-sided short aortic bypass from the arcus aorta to descending aorta via median sternotomy allows simultaneuos repair of both complex aortic coarctation and concomitant cardiac operation. MATERIALS: Four adult patients were underwent Anatomic left-sided short aortic bypass operation for complex aortic coarctation through median sternotomy using deep hypothermic circulatory arrest. Concomitant cardiac operations were Bentall procedure for annuloaortic ectasia in one patient, coronary artery bypass grafting for three vessel disease in two patient, and patch closure of ventricular septal defect in one patient. RESULTS: All patients survived the operation and were alive with patent bypass at a mean follow-up of 36 months. No graft-related complications occurred, and there were no instances of stroke or paraplegia. CONCLUSION: We conclude that single-stage repair of adult aortic coarctation with concomitant cardiovascular lesions can be performed safely using this newest technique
