A Preliminary Evaluation of the Millennial Shopping Experience: Preferences and Plateaus

This study identified and examined the concerns of hotel general managers regarding ethics in the hospitality industry. Thirty-five managers were interviewed during and immediately following the economic recession to determine which ethical issues in the hotel industry and at their own properties concerned them the most. Results showed that more people and organizations attempted to renegotiate hotel rates, which actions, in turn, led to some lapses in ethical behavior. Managers said that because of the economic downturn, they felt pressure from both private owners and corporate headquarters. They also said a lack of work ethic, low motivation, and low pay caused many workers to underperform in ways that raised ethical issues. Managers also mentioned diversity issues and theft by both guests and employees as ethical issues of concern, and shared stories about their experiences.

The largest volcanic eruptions on Earth

Large igneous provinces (LIPs) are sites of the most frequently recurring, largest volume basaltic and silicic eruptions in Earth history. These large-volume (N1000 km3 dense rock equivalent) and large-magnitude (NM8) eruptions produce areally extensive (104–105 km2) basaltic lava flow fields and silicic ignimbrites that are the main building blocks of LIPs. Available information on the largest eruptive units are primarily from the Columbia River and Deccan provinces for the dimensions of flood basalt eruptions, and the Paraná–Etendeka and Afro-Arabian provinces for the silicic ignimbrite eruptions. In addition, three large-volume (675– 2000 km3) silicic lava flows have also been mapped out in the Proterozoic Gawler Range province (Australia), an interpreted LIP remnant. Magma volumes of N1000 km3 have also been emplaced as high-level basaltic and rhyolitic sills in LIPs. The data sets indicate comparable eruption magnitudes between the basaltic and silicic eruptions, but due to considerable volumes residing as co-ignimbrite ash deposits, the current volume constraints for the silicic ignimbrite eruptions may be considerably underestimated. Magma composition thus appears to be no barrier to the volume of magma emitted during an individual eruption. Despite this general similarity in magnitude, flood basaltic and silicic eruptions are very different in terms of eruption style, duration, intensity, vent configuration, and emplacement style. Flood basaltic eruptions are dominantly effusive and Hawaiian–Strombolian in style, with magma discharge rates of ~106–108 kg s−1 and eruption durations estimated at years to tens of years that emplace dominantly compound pahoehoe lava flow fields. Effusive and fissural eruptions have also emplaced some large-volume silicic lavas, but discharge rates are unknown, and may be up to an order of magnitude greater than those of flood basalt lava eruptions for emplacement to be on realistic time scales (b10 years). Most silicic eruptions, however, are moderately to highly explosive, producing co-current pyroclastic fountains (rarely Plinian) with discharge rates of 109– 1011 kg s−1 that emplace welded to rheomorphic ignimbrites. At present, durations for the large-magnitude silicic eruptions are unconstrained; at discharge rates of 109 kg s−1, equivalent to the peak of the 1991 Mt Pinatubo eruption, the largest silicic eruptions would take many months to evacuate N5000 km3 of magma. The generally simple deposit structure is more suggestive of short-duration (hours to days) and high intensity (~1011 kg s−1) eruptions, perhaps with hiatuses in some cases. These extreme discharge rates would be facilitated by multiple point, fissure and/or ring fracture venting of magma. Eruption frequencies are much elevated for large-magnitude eruptions of both magma types during LIP-forming episodes. However, in basaltdominated provinces (continental and ocean basin flood basalt provinces, oceanic plateaus, volcanic rifted margins), large magnitude (NM8) basaltic eruptions have much shorter recurrence intervals of 103–104 years, whereas similar magnitude silicic eruptions may have recurrence intervals of up to 105 years. The Paraná– Etendeka province was the site of at least nine NM8 silicic eruptions over an ~1 Myr period at ~132 Ma; a similar eruption frequency, although with a fewer number of silicic eruptions is also observed for the Afro- Arabian Province. The huge volumes of basaltic and silicic magma erupted in quick succession during LIP events raises several unresolved issues in terms of locus of magma generation and storage (if any) in the crust prior to eruption, and paths and rates of ascent from magma reservoirs to the surface.

Low SES primary school students engaging in an after-school robotics program

Recent attention in education within many western contexts has focused on improved outcomes for students, with a particular focus on closing the gap between those who come from disadvantaged backgrounds and the rest of the student population. Much of this attention has supported a set of simplistic solutions to improving scores on high stakes standardized tests. The collateral damage (Nichols & Berliner, 2007) of such responses includes a narrowing of the curriculum, plateaus in gain scores on the tests, and unproductive blame games aimed by the media and politicians at teachers and communities (Nichols & Berliner, 2007; Synder, 2008). Alternative approaches to improving the quality and equity of schooling remain as viable alternatives to these measures. As an example in a recent study of school literacy reform in low SES schools, Luke, Woods and Dooley (2011) argued for the increase of substantive content and intellectual quality of the curriculum as a necessary means to re-engaging middle school students, improving outcomes of schooling and achieving a high quality, high equity system. The MediaClub is an afterschool program for students in years 4 to 7 (9-12 year old) at a primary school in a low SES area of a large Australian city. It is run as part of an Australian Research Council funded research project. The aim of the program has been to provide an opportunity for students to gain expertise in digital technologies and media literacies in an afterschool setting. It was hypothesized that this expertise might then be used to shift the ways of being literate that these students had to call on within classroom teaching and learning events. Each term, there is a different focus on digital media, and information and communication technology (ICT) activities in the MediaClub. The work detailed in this chapter relates to a robotics program presented as one of the modules within this afterschool setting. As part of the program, the participants were challenged to find creative solutions to problems in a constructivist-learning environment.

The adventure of the refrain : composing with improvised music

This practice-based inquiry investigates the process of composing notated scores using improvised solos by saxophonists John Butcher and Anthony Braxton. To compose with these improvised sources, I developed a new method of analysis and through this method I developed new compositional techniques in applying these materials into a score. This method of analysis and composition utilizes the conceptual language of Gilles Deleuze and Felix Guattari found in A Thousand Plateaus. The conceptual language of Deleuze and Guattari, in particular the terms assemblage, refrain and deterritorialization are discussed in depth to give a context for the philosophical origins and also to explain how the language is used in reference to improvised music and the compositional process. The project seeks to elucidate the conceptual language through the creative practice and in turn for the creative practice to clarify the use of the conceptual terminology. The outcomes of the research resulted in four notated works being composed. Firstly, Gravity, for soloist and ensemble based on the improvisational language of John Butcher and secondly a series of 3 studies titled Transbraxton Studies for solo instruments based on the improvisational-compositional language of Anthony Braxton. The implications of this research include the application of the analysis method to a number of musical contexts including: to be used in the process of composing with improvised music; in the study of style and authorship in solo improvisation; as a way of analyzing group improvisation; in the analysis of textural music including electronic music; and in the analysis of music from different cultures—particularly cultures where improvisation and per formative aspects to the music are significant to the overall meaning of the work. The compositional technique that was developed has further applications in terms of an expressive method of composing with non-metered improvised materials and one that merges well with the transcription method developed of notating pitch and sounds to a timeline. It is hoped that this research can open further lines of enquiry into the application of the conceptual ideas of Deleuze and Guattari to the analysis of more forms of music.

Spatially-explicit modelling of grassland classes - an improved method of integrating a climate-based classification model with interpolated climate surfaces

Spatially-explicit modelling of grassland classes is important to site-specific planning for improving grassland and environmental management over large areas. In this study, a climate-based grassland classification model, the Comprehensive and Sequential Classification System (CSCS) was integrated with spatially interpolated climate data to classify grassland in Gansu province, China. The study area is characterized by complex topographic features imposed by plateaus, high mountains, basins and deserts. To improve the quality of the interpolated climate data and the quality of the spatial classification over this complex topography, three linear regression methods, namely an analytic method based on multiple regression and residues (AMMRR), a modification of the AMMRR method through adding the effect of slope and aspect to the interpolation analysis (M-AMMRR) and a method which replaces the IDW approach for residue interpolation in M-AMMRR with an ordinary kriging approach (I-AMMRR), for interpolating climate variables were evaluated. The interpolation outcomes from the best interpolation method were then used in the CSCS model to classify the grassland in the study area. Climate variables interpolated included the annual cumulative temperature and annual total precipitation. The results indicated that the AMMRR and M-AMMRR methods generated acceptable climate surfaces but the best model fit and cross validation result were achieved by the I-AMMRR method. Twenty-six grassland classes were classified for the study area. The four grassland vegetation classes that covered more than half of the total study area were "cool temperate-arid temperate zonal semi-desert", "cool temperate-humid forest steppe and deciduous broad-leaved forest", "temperate-extra-arid temperate zonal desert", and "frigid per-humid rain tundra and alpine meadow". The vegetation classification map generated in this study provides spatial information on the locations and extents of the different grassland classes. This information can be used to facilitate government agencies' decision-making in land-use planning and environmental management, and for vegetation and biodiversity conservation. The information can also be used to assist land managers in the estimation of safe carrying capacities which will help to prevent overgrazing and land degradation.

She mentions propensities discussed in her article including scientize and template theoretical frameworks.

Fabrication and evaluation of 1 Ah silver/metal hydride cells

Silver/metal hydride (Ag/MH) cells of about 1 Ah capacity have been fabricated and their discharge characteristics at different rates of discharge, faradaic efficiency, cycle life and a.c. impedance have been evaluated. These cells comprise metal-hydride electrodes prepared by employing similar to 60 mu m powder of an AB(2)-Laves phase alloy of nominal composition Zr0.5Ti0.5V0.6Cr0.2Ni1.2 with PTFE binder on a nickel-mesh substrate as the negative plates and commercial-grade silver electrodes as the positive plates. The cells are positive limited and exhibit two distinct voltage plateaus characteristic of two-step reduction of AgO to Ag during their low rates of discharge between C/20 and C/10. This feature is, however, absent when the cells are discharged at C/5 rate. On charging the cells to 100% of their capacity, the faradaic efficiency is found to be 100%. The impedance of the Ag/MH cell is essentially due to the impedance of the silver electrodes, since MH electrodes offer negligible impedance. The cells may be subjected to a large number of charge-discharge cycles with little deterioration.

Kansallisvaltion teräsmiehestä valtakunnan sovittelijaksi : Poliisikulttuurin psykohistorialliset solmukohdat 1930-1997

From Steely Nation-State Superman to Conciliator of Economical Global Empire – A Psychohistory of Finnish Police Culture 1930-1997 My study concerns the way police culture has changed within the societal changes in Finnish society between 1930 and 1997. The method of my study was psycho-historical and post-structural analysis. The research was conducted by examining the psycho-historical plateaus traceable within Finnish police culture. I made a social diagnosis of the autopoietic relationship between the power-holders of Finnish society and the police (at various levels of hierarchical organization). According to police researcher John P. Crank, police culture should be understood as the cognitive processes behind the actions of the police. Among these processes are the values, beliefs, rituals, customs and advice which standardize their work and the common sense of policemen. According to Crank, police culture is defined by a mindset which thinks, judges and acts according to its evaluations filtered by its own preliminary comprehension. Police culture consists of all the unsaid assumptions of being a policeman, the organizational structures of police, official policies, unofficial ways of behaviour, forms of arrest, procedures of practice and different kinds of training habits, attitudes towards suspects and citizens, and also possible corruption. Police culture channels its members’ feelings and emotions. Crank says that police culture can be seen in how policemen express their feelings. He advises police researchers to ask themselves how it feels to be a member of the police. Ethos has been described as a communal frame for thought that guides one’s actions. According to sociologist Martti Grönfors, the Finnish mentality of the Protestant ethic is accentuated among Finnish policemen. The concept of ethos expresses very well the self-made mentality as an ethical tension which prevails in police work between communal belonging and individual freedom of choice. However, it is significant that it is a matter of the quality of relationships, and that the relationship is always tied to the context of the cultural history of dealing with one’s anxiety. According to criminologist Clifford Shearing, the values of police culture act as subterranean processes of the maintenance of social power in society. Policemen have been called microcosmic mediators, or street corner politicians. Robert Reiner argues that at the level of self-comprehension, policemen disparage the dimension of politics in their work. Reiner points out that all relationships which hold a dimension of power are political. Police culture has also been called a canteen culture. This idea expresses the day-to-day basis of the mentality of taking care of business which policing produces as a necessity for dealing with everyday hardships. According to police researcher Timo Korander, this figurative expression embodies the nature of police culture as a crew culture which is partly hidden from police chiefs who are at a different level. This multitude of standpoints depicts the diversity of police cultures. According to Reiner, one should not see police culture as one monolithic whole; instead one should assess it as the interplay of individuals negotiating with their environment and societal power networks. The cases analyzed formed different plateaus of study. The first plateau was the so-called ‘Rovaniemi arson’ case in the summer of 1930. The second plateau consisted of the examinations of alleged police assaults towards the Communists during the Finnish Continuation War of 1941 to 1944 and the threats that societal change after the war posed to Finnish Society. The third plateau was thematic. Here I investigated how using force towards police clients has changed culturally from the 1930s to the 1980s. The fourth plateau concerned with the material produced by the Security Police detectives traced the interaction between Soviet KGB agents and Finnish politicians during the long 1970s. The fifth plateau of larger changes in Finnish police culture then occurred during the 1980s as an aftermath of the former decade. The last, sixth plateau of changing relationships between policing and the national logic of action can be seen in the murder of two policemen in the autumn of 1997. My study shows that police culture has transformed from a “stone cold” steely fixed identity towards a more relational identity that tries to solve problems by negotiating with clients instead of using excessive force. However, in this process of change there is a traceable paradox in Finnish policing and police culture. On the one hand, policemen have, at the practical level, constructed their policing identity by protecting their inner self in their organizational role at work against the projections of anger and fear in society. On the other hand, however, they have had to safeguard themselves at the emotional level against the predominance of this same organizational role. Because of this dilemma they must simultaneously construct both a distance from their own role as police officers and the role of the police itself. This makes the task of policing susceptible to the political pressures of society. In an era of globalization, and after the heyday of the welfare state, this can produce heightened challenges for Finnish police culture.

Magnetization properties of some quantum spin ladders

The experimental realization of various spin ladder systems has prompted their detailed theoretical investigations. Hen we study the evolution of ground-state magnetization with an external magnetic field for two different antiferromagnetic systems: a three-legged spin-1/2 ladder, and a two-legged spin-1/2 ladder with an additional diagonal interaction. The finite system density-matrix renormalization-group method is employed for numerical studies of the three-chain system, and an effective low-energy Hamiltonian is used in the limit of strong interchain coupling to study the two- and three-chain systems. The three-chain system has a magnetization plateau at one-third of the saturation magnetization. The two-chain system has a plateau at zero magnetization due to a gap above the singlet ground state. It also has a plateau at half of the saturation magnetization for a certain range of values of the couplings. We study the regions of transitions between plateaus numerically and analytically, and find that they are described, at first order in a strong-coupling expansion, by an XXZ spin-1/2 chain in a magnetic field; the second-order terms give corrections to the XXZ model, We also study numerically some low-temperature properties of the three-chain system, such as the magnetization, magnetic susceptibility and specific heat.

Tensile flow behaviour of 2.25Cr-1Mo ferritic steel base metal and simulated heat affected zone structures of 2.25Cr-1Mo weld joint

Tensile tests in the temperature range 298 to 873 K have been performed on 2.25Cr-1Mo base metal and simulated heat affected zone (HAZ) structures of its weld joint, namely coarse grain bainite, fine grain bainite and intercritical structure. Tensile flow behaviour of all the microstructural conditions could be adequately described by the Hollomon equation (sigma = K-1 epsilon(n1)) at higher (> 623 K) temperatures. Deviation from the Hollomon equation was observed at low strains and lower (< 623 K) temperatures. The Ludwigson modification of Hollomon's equation, sigma = K-1 epsilon(n1) + exp (K-2 + n(2) epsilon), was found to describe the flow curve. In general, the flow parameters n(1), K-1, n(2) and K-2 were found to decrease with increase in temperature except in the intermediate temperature range (423 to 623 K). Peaks/plateaus were observed in their variation with temperature in the intermediate temperature range coinciding with the occurrence of serrated flow in the load-elongation curve. The n(1) Value increased and the K-1 value decreased with the type of microstructure in the order: coarse grain bainite, fine grain bainite, base metal and intercritical structure. The variation of nl with microstructure has been rationalized on the basis of mean free path (MFP) of dislocations which is directly related to the inter-particle spacing. Larger MFP of dislocations lead to higher strain hardening exponents n(1).
