AbstractMycoplasma bovisis an important and emerging cause of respiratory disease and arthritis in feedlot cattle and young dairy and veal calves, and has a variety of other disease manifestations in cattle.M. bovisis certainly capable of causing acute respiratory disease in cattle, yet the attributable fraction has been difficult to estimate. In contrast,M. bovisis more accepted as a cause of chronic bronchopneumonia with caseous and perhaps coagulative necrosis, characterized by persistent infection that seems poorly responsive to many antibiotics. An understanding of the disease has been recently advanced by comparisons of natural and experimentally induced disease, development of molecular diagnostic tools, and understanding some aspects of virulence, yet uncertainties regarding protective immunity, the importance of genotypic diversity, mechanisms of virulence, and the role of co-pathogens have restricted our understanding of pathogenesis and our ability to effectively control the disease. This review critically considers the relationship betweenM. bovisinfection and the various manifestations of the bovine respiratory disease complex, and addresses the pathogenesis, clinical and pathologic sequelae, laboratory diagnosis and control of disease resulting fromM. bovisinfection in the bovine respiratory tract.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

This chapter traces the relationship between political authorizing environments, international development organization (IDO) management, and IDO field agents, drawing on the empirics presented in chapters 6 and 7. It digs into the experience of working for USAID as compared to DFID. It also extends the discussion of delegation to implementing contractors and brings this book’s theorizing of Navigation by Judgment into conversation with other foreign aid solutions aimed at incorporating local knowledge, such as establishing country offices or ensuring projects have country ownership. This chapter connects Part II’s empirics more tightly to the mechanisms theorized in Part I , particularly the role of authorizing environment insecurity and the need to “manage up” (Chapter 4) and their implications for the workplace experience of agents (Chapter 3) and the entry and exit of personnel.

The cornerstone of cognitive treatment (CT) for OCD is based upon the knowledge that unwanted intrusions are essentially a universal experience. As such, it is not the presence of the intrusion that is problematic but rather the associated meaning or interpretation. Treatment is flexible, depending upon the nature of the appraisals and beliefs, but can include strategies focused on inflated responsibility and overestimation of threat, importance and control of thoughts, and the need for perfectionism and certainty. The role of concealment and the relationship to personal values are important maintaining and etiological factors. The short-term and long-term treatment outcome is reviewed, along with predictors of treatment response and mechanisms of action, and the chapter concludes with future directions regarding CT for OCD.

We examine the effects of different types of executive incentives on technological innovation of declining firms and the moderating effects of the degree of decline and organisational slack on executive incentives and enterprise technological innovation. We also assess the synergetic effects of different types of executive incentives on technological innovation of declining enterprises. We find the following: first, executive compensation incentive, equity incentive and control incentives are beneficial to promote technological innovation in declining enterprises. Second, the degree of decline negatively moderates the relationship between equity incentive and technological innovation. Third, organisational slack positively moderates the relationship between equity incentive and technological innovation, as well as the relationship between control incentives and technological innovation, especially for severely declining enterprises. Fourth, there are synergistic effects between executive control incentive and compensation incentive, control incentives and equity incentive on technological innovation. The contributions are as follows: first, taking declining enterprises as sample, we suggest that to increase the role of compensation incentive and equity incentive in promoting technological innovation in declining enterprises, the control incentives should be strengthened. Second, organisational slack should be fully exploited for severely declining enterprises so that executives should have the motivation and conditions to carry out technological innovation and further help declining enterprises to turnaround successfully.

This study examined the relationship between epistemological beliefs, meta-cognition, and student achievement in a hypermedia learning environment. Epistemological beliefs refer to beliefs about the nature of knowledge and knowing (see review by Hofer & Pintrich, 1997) and metacognition refers to the ability to reflect upon, understand, and control one's learning (Schraw & Dennison, 1994). We predicted that the epistemological beliefs and meta-cognitive awareness of 116 preservice teachers would be significantly related to achievement in a hypermedia tutorial. Achievement was measured by a posttest based on the tutorial content. Results from a forced-order, hierarchical regression analysis indicated that reading comprehension, GPA, and three of the five epistemological beliefs (i.e., fixed ability, omniscient authority, and quick learning) significantly predicted posttest performance. Belief in omniscient authority and fixed ability being related to lower achievement supports previous research. Contrary to our expectations, a belief in quick learning was positively correlated with achievement. Educational and instructional design implications are discussed.

<p><em>This study aims to determine the effect of the antecedents of Supply chain quality risk management (SCQRM) implementation on organizational performance with the moderating role of organizational culture in the Indonesian Navy. Based on data from questionnaire survey data totaling 260 Indonesian Navy officers, the SCQRM theory model is proposed and the structural equation model is used to test the proposed hypothesis. The results show that strategic leadership, information, and control mechanisms are significant antecedents of SCQRM implementation. Furthermore, strategic leadership and information significantly contribute to organizational performance. An interesting finding is that control mechanisms do not have a direct impact on organizational performance, but they do contribute indirectly to organizational performance mediated by SCQRM implementation. Also, SCQRM implementation significantly contributes to organizational performance and the moderating effect of organizational culture strengthens the relationship between SCQRM implementation and organizational performance. This study focuses on the concept and implementation of SCQRM in Indonesian Navy logistics with the role of strategic leadership, information, control mechanisms, and organizational culture to improve organizational performance using single respondents and expert perceptions, namely Indonesian Navy Officers. The managerial implications suggest that complementary benefits arise from the adoption of a more holistic approach to the management of supply chain quality risk at the organizational level with</em><em> </em><em>supported the role of strategic leadership, information, control mechanisms, and organizational culture will improve organizational performance. Three contributions to science in the development of SCQRM theory. <strong>First</strong>, this study develops an SCQRM theoretical model with three unique dimensions (supplier development, risk management integration, and proactive product recall). <strong>Second</strong>, this study provides a new perfection of how the complementarity system of SCQRM is operated to improve organizational performance. Moreover, the findings imply that a successful SCQRM implementation is built on a complementarity power in risk management resources and routines. The multiple manifestations of the three SCQRM dimensions are all driven by a cohesive, yet unobserved synergy, which also forms one of the competencies of the organization. <strong>Third</strong>, this study also provides a new perfection on the role of strategic leadership, information and control mechanisms as antecedents of SCQRM implementation, and the moderating role of organizational culture that strengthens the relationship between SCQRM implementation and organizational performance</em><em>.   </em><strong></strong></p>

The Concentrate Questions and Answers series offers the best preparation for tackling exam questions and coursework. Each book includes typical questions, suggested answers with commentary, illustrative diagrams, guidance on how to develop your answer, suggestions for further reading, and advice on exams and coursework. This chapter explores important issues in company management and corporate governance, starting by examining the role of directors and shareholders (and the relationship between them) and the separation of ‘ownership and control’. Since the early 1990s, the governance of listed companies has been dominated by self-regulatory codes (currently the UK Corporate Governance Code). This chapter examines how these codes operate and considers key themes in corporate governance, including the role of non-executive directors and auditors; the position of institutional investors; and executive remuneration.

Summary Metabolic changes resulting from obesity, insulin insensitivity, and imbalances in hormones such as adiponectin, leptin, resistin, apelin and visfatin, which are derived from white adipose tissue-derived hormone, are directly linked to both colon cancer (CC) and inflammatory bowel diseases increasing tissue-derived risk. We conducted this study to evaluate the relationship between the circulating concentrations of adiponectin, leptin, resistin, apelin and visfatin and colon adenoma and CC. Our study included 90 participants aged >18 years who were divided into three groups: colon cancer, adenoma and control. The serum concentrations of the investigated adipohormones were measured with ELISA in 30 patients with colon adenoma, 30 with CC and 30 controls with no colon pathology. Demographic, anthropometric, metabolic and hormonal parameters were also recorded. The group means were compared by using one-way analysis of variance (ANOVA). Dual comparisons between groups were analyzed with the Tukey test. Pearson correlation coefficient was used to determine the relation between continuous variables. Adiponectin and leptin levels in patients with adenomas (p<0.000; p<0.000, respectively) and CC (p<0.000; p<0.000, respectively) were lower than in controls. Apelin level in patients with CC (p<0.000; p<0.000, respectively) was lower than in patients with adenomas and in controls. Resistin and visfatin levels in patients with CC (p<0.000; p<0.000, respectively) were higher than in patients with adenomas and in controls.

Purpose Accounting can affect and determine power relations. Previous studies have emphasized how accounting has been used by “central” powers; less is known from the perspective of “local” power and its capacity to resist and protect its interests. The purpose of this paper is to investigate the relationship between the Archbishop’s Seminary of Siena (ASS) (local) and Roman ecclesiastic institutions (central). This study contributes to filling the existing gap in the literature regarding how accounting could be used as a tool for deception in local/central power relations. Design/methodology/approach The research methodology is based on a case study and archival research. The ASS case study was analyzed through its archive, made up for the most part of accounting books. As to the approach adopted, the authors used the Foucault framework to observe power relations in order to identify possible ways in which accounting can be employed as a factor of deception. Findings Power relations between the ASS and Roman ecclesiastic institutions were maintained through a system of reporting that limited the influence of the ecclesiastical power of Rome over the Seminary’s administration and control. The relationship thus runs contrary to the findings in previous studies. The accounting system was managed as a factor of deception in favor of local interests and the limitation of central ecclesiastic power. Research limitations/implications This study contributes to enhancing the existing literature on governmentality, proposing a different perspective in which power relations are based on the use of accounting. The Foucaldian approach demonstrates its validity, even though the power relations under consideration have the unusual feature of occurring within the context of religious institutions. Originality/value This study on the ASS has allowed the identification of two relevant points: the local/central dichotomy is consistent with the logic of power relations as theorized by Foucault, even in cases where it highlights the role of a local power in limiting the flow of information to a central one; and the ASS accounting system was used as a factor of deception.
