This research will investigate what it will take to develop principals who will embrace the recommendations of reform as proposed by National Association of Secondary School Principals (NASSP, 1996) in the Breaking Ranks document. Breaking Ranks is based on the belief that it is within the dynamics of the school culture that principals must gain insight into strategies for improving the schools for which they are held responsible. Given this context, it is important to examine perspectives that are held by principals who lead schools that embrace the concepts of reform as proposed by NASSP, thereby, could be deemed “Breaking Ranks” schools. It is within these schools that the new role of the principal develops. NASSP has identified seven key recommendations for leadership development; “attributes that need nourishing” (p. 12) for the success of school reform. The seven recommendations are included in Breaking Ranks. ^ The purpose of this study is to identify and describe how principals put the seven recommendations into practice as they function in their schools. In addition, this study will gather information on the characteristics, support, skills, and training these principals identify as critical aspects and components of their success. This is a study of principal leadership at four high school sites where “Breaking Ranks” principals have been identified. ^ This research plan will be designed to utilize an inquiry-based process with a panel of experts and four “Breaking Ranks” principals. This study will describe: (1) how a panel of experts identify what they believe needs to be done in order to put the recommendations of the Breaking Ranks document into practice and their identification of principals who are breaking ranks; (2) how identified principals say they have been able to put the recommendations of the Breaking Ranks document into practice; (3) How both groups identify and describe: (a) the characteristics and behaviors of a “Breaking Ranks” principal; (b) the new leadership skills as described by the seven recommendations identified in the Breaking Ranks document; (c) the support necessary in order to meet the recommendations in the Breaking Ranks document; and (d) The training needed in order to become “Breaking Ranks” principals; and (4) how the process of creating “Breaking Ranks” principals can be described by experts who have studied it theoretically and principals who have demonstrated it in their schools. ^

The resounding message extracted from the service literature is that employees serve pivotal functions in the overall guest experience. This is of course due to the simultaneous delivery of personalized service provision with resultant consumption of those services. This simultaneous delivery and consumption cycle is at times challenged by a perceived desire to accommodate guest request that may violate, to a greater or lesser degree, an organizational rule. This is important to note because increased interactions with customers enable frontline employees to have a better sense of what customers want from the company as well as from the company itself (Bitner, et al, 1994). With that platform established, then why are some employees willing to break organizational rules and risk disciplinary action to better service a customer? This study examines the employee personality, degree of autonomy, job meaning, and co-worker influence on an employee's decision to break organizational rules. The results of this study indicate that co-worker influence exerted a minimal influence on employee decision to break rules while the presence of societal consciousness exerted a much stronger influence. Women reported that they were less likely to engage in rule divergence, and significant correlations were present when filtered by years in current position, and years in the industry.

The conventional mechanism of fermion mass generation in the Standard Model involves Spontaneous Symmetry Breaking (SSB). In this thesis, we study an alternate mechanism for the generation of fermion masses that does not require SSB, in the context of lattice field theories. Being inherently strongly coupled, this mechanism requires a non-perturbative approach like the lattice approach.
In order to explore this mechanism, we study a simple lattice model with a four-fermion interaction that has massless fermions at weak couplings and massive fermions at strong couplings, but without any spontaneous symmetry breaking. Prior work on this type of mass generation mechanism in 4D, was done long ago using either mean-field theory or Monte-Carlo calculations on small lattices. In this thesis, we have developed a new computational approach that enables us to perform large scale quantum Monte-Carlo calculations to study the phase structure of this theory. In 4D, our results confirm prior results, but differ in some quantitative details of the phase diagram. In contrast, in 3D, we discover a new second order critical point using calculations on lattices up to size $ 60^3$. Such large scale calculations are unprecedented. The presence of the critical point implies the existence of an alternate mechanism of fermion mass generation without any SSB, that could be of interest in continuum quantum field theory.

Many groups had expressed support for the EU’s circular economy package, now abandoned with the promise of “more ambitions” proposals. But can we afford to wait?

An essay on the emergent methodology of media archaeology, in realtion to the material turn in approaches to digital media. In particular, this article advocates taking up Siegfried Zielinski's concept of 'anarchaeology', but in a different sense to the way it was originally proposed, in order to emphasise the political potentials of a media (an)archaeological methodological approach.

Impactive contact between a vibrating string and a barrier is a strongly nonlinear phenomenon that presents several challenges in the design of numerical models for simulation and sound synthesis of musical string instruments. These are addressed here by applying Hamiltonian methods to incorporate distributed contact forces into a modal framework for discrete-time simulation of the dynamics of a stiff, damped string. The resulting algorithms have spectral accuracy, are unconditionally stable, and require solving a multivariate nonlinear equation that is guaranteed to have a unique solution. Exemplifying results are presented and discussed in terms of accuracy, convergence, and spurious high-frequency oscillations.
