Abstract We question Baumard's underlying assumption that humans have a propensity to innovate. Affordable transportation and energy underpinned the Industrial Revolution, making mass production/consumption possible. Although we cannot accept Baumard's thesis on the Industrial Revolution, it may help explain why complexity and innovation increase rapidly in the context of abundant energy.

AbstractThe hippocampus is critical for learning and memory and may be separated into anatomically-defined hippocampal subfields (aHPSFs). Hippocampal functional networks, particularly during resting state, are generally analyzed using aHPSFs as seed regions, with the underlying assumption that the function within a subfield is homogeneous, yet heterogeneous between subfields. However, several prior studies have observed similar resting-state functional connectivity (FC) profiles between aHPSFs. Alternatively, data-driven approaches investigate hippocampal functional organization without a priori assumptions. However, insufficient spatial resolution may result in a number of caveats concerning the reliability of the results. Hence, we developed a functional Magnetic Resonance Imaging (fMRI) sequence on a 7 T MR scanner achieving 0.94 mm isotropic resolution with a TR of 2 s and brain-wide coverage to (1) investigate the functional organization within hippocampus at rest, and (2) compare the brain-wide FC associated with fine-grained aHPSFs and functionally-defined hippocampal subfields (fHPSFs). This study showed that fHPSFs were arranged along the longitudinal axis that were not comparable to the lamellar structures of aHPSFs. For brain-wide FC, the fHPSFs rather than aHPSFs revealed that a number of fHPSFs connected specifically with some of the functional networks. Different functional networks also showed preferential connections with different portions of hippocampal subfields.

Abstract Differentiation is a foundational premise in the study of middle powers, as evident in the way that the relevant literature distinguishes these states from the great powers and smaller states. Despite the underlying assumption of differentiation, the middle power literature has rarely engaged theoretically with the concept. This paper seeks to make more explicit this basis of differentiation in the study of middle powers, by advancing a new framework for middle power behavior that draws on differentiation theory. The framework makes the case that it is the differentiated structure in international politics – a departure from the dominant neorealist understanding of structure – that enables the behavior of middle powers. The effects of this differentiated structure are activated by the relative, relational, and social power politics that middle powers engage in, in a particular time and place. Through this process, middle powers are able to leverage their ‘middlepowerness’ in international politics by weakening stratification particularly where the great powers are concerned, and strengthening functional differentiation through taking on key and distinctive roles. By putting differentiation at the core of a framework for middle power behavior, the paper strives to make a constructive contribution to the theorizing of middle powers.

Abstract Background Screening for distress and referral for the provision of psychosocial care is currently the preferred approach to the management of distress in patients with cancer. To date, this approach has shown a limited effect on the reduction of distress. Recent commentaries have argued that the implementation of distress screening should be improved. On the other hand, the underlying assumption that a referral for psychosocial care is required for distressed patients can be questioned. This has led to the development of an alternative approach, called emotional support and case finding. Purpose In the context of finding innovative solutions to tomorrow’s health challenges, we explore ways to optimize distress management in patients with cancer. Methods and Results We discuss three different approaches: (i) optimization of screening and referral, (ii) provision of emotional support and case finding, and (iii) a hybrid approach with multiple assessments, using mobile technology. Conclusions We suggest continued research on the screening and referral approach, to broaden the evidence-base on improving emotional support and case finding, and to evaluate the utility of multiple assessments of distress with new interactive mobile tools. Lessons learned from these efforts can be applied to other disease areas, such as cardiovascular disease or diabetes.

Purpose – The purpose of this paper is to increase the understanding of the main challenges of the contracting process and project contracts in the context of project business characterized by a high level of complexity and uncertainty. The authors argue that understanding contracting as a flexible process and as a business tool will contribute to creating more value in projects which are implemented in constantly changing circumstances or which require gradual and iterative development. Design/methodology/approach – This is a conceptual paper with illustrative examples from the software industry. Findings – A prevailing approach for both managing contracts and the contracting process focuses on careful planning and drafting of contracts that protect each party in the case of conflicts and disagreements. The underlying assumption is that all activities can be planned and documented in a formal contract. According to this approach, the contracting process is seen only as a bargaining negotiation and the project contract as a detailed agreement of the responsibilities and safeguarding clauses to protect one’s position in the event of conflicts and failures. However, in the context of project business characterized by complexity and uncertainty, there is a need for flexible project contracts. The authors suggest that there are two fundamentally different approaches to implementing flexibility in both the contracting process and the project contract: postponing the decision until there is adequate information for decision making or making decisions that allow flexible adaptation to changes during the project lifecycle. Practical implications – The authors suggest that organizations in project business should pay closer attention to how contracts are formed and how flexibility is introduced to projects. Organizations are encouraged to see contracts as a business tool, not as rigid documents which are taken into use in case something goes wrong. Originality/value – This paper contributes to the understanding of how to adapt the contracting process to overcome challenges related to uncertainty, especially during the early phases of the project lifecycle. The authors provide a novel perspective on contracting as a process that extends over the lifecycle of a project and on the project contract as an agreement between parties formed during the contracting process. This perspective includes formal contract documents as well as various other documents, oral communication, commitments, actions and incidents.

Emerging information that rape primarily occurs between acquaintances has not only exploded our understanding of this problem, but forced a reexamination of our notions of prevention. In recent years, the vast majority of rape prevention programs have taken the format of educational workshops, with the underlying assumption that change in rape-supportive ideologies will decrease the actual incidence of sexual aggression. This article critically reviews such rape prevention education with particular focus on common techniques such as: “debunking” rape mythology, generating participant interaction, providing sexuality education and a feminist orientation, and avoiding confrontational approaches. Finally, theoretical and practical concerns are discussed regarding previous experiences of sexual victimization or perpetration, the conceptualization and use of outcome measures, issues of program facilitation, and processes underlying change in rape-supportive ideologies. It is concluded that future research must seriously address these many issues through thoughtful conceptualization and rigorous experimentation, so that the promise of rape prevention can be fully realized.

An underlying assumption of quality of life outcome research is that after some intervention a “steady-state” of quality of life is reached which can be identified as an endpoint, and, hence, the “outcome.” However, in some disease processes, no so such steady-state is reached. The hypothesis presented is that a disease process with a waxing and waning course will make it difficult to determine a quality of life endpoint. After clinical observation, a pilot study of patients with either diabetic or idiopathic gastroparesis with gastric neurostimulation their records were reviewed to identify the number of clinic visits, the number of clinic visits in which the patients were asymptomatic, much improved, improved, no change, worse, or much worse. These changes were defined as “transitions.” A “transition ratio” was calculated by dividing the number of transitions by the number of clinic visits. Preliminary results showed that of 32 patients, the median number of clinic encounters was 8 (1–35), and the median number of transitions 4 (0–22). The average transition ration was . In the case of gastroparesis, over half of all clinical encounters were associated with a transition. The implication of the hypothesis and preliminary finding suggests a difficulty to identify when the symptomatic endpoint was reached. Other methods to assess the effects of treatment in such a disease process are required to fully understand the effects of treatment on quality of life.

An underlying assumption that ocurs in both conventional wisdom and in many academic analyses of political behavior is the notion that a critical linkage exists between political change and economic performance. The assumption is that economic growth is either a precondition or a correlate of democracy and political stability. Little empirical research has been done to test the validity of this widely held assumption as it applies to multicultural societies. Moreover, in the African environment, the assumption seems to operate only in selected cases or in ways that defy categorization. Jerry Rawlings, for example, said he led his first coup d’etat in Ghana because the government was going to devalue the currency; he led his second coup, in part, because the next government was going to devalue; and, during his own tenure in office, he has presided over a 1000 percent devaluation.

Background: Results from a clinical trial can either support the efficacy and safety of a new compound or fail to provide such evidence. One reason for ‘non[1]positive’ result is due to the underlying assumption of normality and homogeneity of variances, which are quite often violated when analyzing data from clinical trials, despite randomization. A question of interest is can we obtain more informative results when using mixture of normal distributions or linear models (MLMs) in such cases. Introduction: MLM can be used when traditional methods fail. MLMs “search” within the variability in data to identify components or subgroups of individuals (also known as latent classes) who have common intercepts and common slopes of change in a variable/endpoint of interest but whose intercepts and slopes are different from other subsets of patients. Thus, MLMs can be used to identify subgroups of patients exhibiting differential response to treatment within each treatment arm. The purpose of our study was to examine the usefulness of using MLM in such circumstances. Methods: Data of 155 subjects taken from a Multicenter, randomized, double blind, placebo controlled trial that evaluated the efficacy of Cpn10, administered twice weekly subcutaneously to treat Rheumatoid Arthritis was taken to evaluate the usefulness of MLM. The primary efficacy measure ACR20 was analyzed using a 3-step process: first, MLM was used to estimate RA duration using a 3-component model. The second step took the results of the first step to inform the logistic model and its analyses. Model was fitted with an intercept, MLM components, treatment arm, RA duration (linear and quadratic), dose response (modeled as an interaction effect), age and baseline weight. LOCF was used to impute for missing data. Data was analyzed using MLM and SAS v 9.0. Results: The model was a good fit to the data with a likelihood ratio significant at p=0.026, and a significant increase in the -2log L. We also observed low p-values for those variables that were non normal. Overall and for the 75 mg dose, Cpn 10 was efficacious relative to placebo, p<0.050. We also observed that dose response was significant at p><0.15 Conclusion: The use of MLM adds value because it can be used to understand the disease experience or the value of treatment when traditional statistical methods cannot. Key words: Mixture of linear models, normality, entropy.

This paper explores the philosophy of emotion in classical India. Although some scholars have endeavored to develop a systematic philosophy of emotion based on rasa theory, no serious effort has been made to read the relationship between emotion and the self in light of rasa theory. This exclusion, I argue, is an outcome of a broader presupposition that the 'self' in classical Indian philosophies is outside the scope of emotion. A fresh reading of classical Sanskrit texts finds this premise baseless. With an underlying assumption that emotion and self are inherently linked, this paper explores similarities between the Indian and Chinese approaches.
