Generating and transforming representations in design ideation

The complexity of the current world is contributing to an increased dependency on innovative approaches and competences for solving open-ended problems and adjusting to multi-layered work environments. Creative ideation is valued not only in traditional creative fields such as design, craft and art, but also in all areas of work life. In design ideation the focus is on seeing beyond the obvious and developing personal constraints on the design task. Therefore, it can be seen as increasing the creativity in problem solving in general. Ideation is important as it is the basis for the rest of the design process. However, the research concerning design ideation is still sparse in Finland, as previous research has emphasised the entire design process. Accordingly there is lack of knowledge, concepts and definitions of ideation to support communication in designing and design education. The aim of this study was to understand design ideation and aspects that inspire and guide designers in the idea generation process. The study explored the conceptual and material premises for ideation, ways of creating novel standpoints towards ideation and the nature of the design context. The study used multiple qualitative methods; data were collected from a virtual e-learning database, by interviewing and using a mobile, context-sensitive data-collecting tool. The data-analyses applied qualitative content analysis. The study explored student teachers’ and professional designers’ design thinking in the ideation focusing on material resources and materially embodied practices for generating and transforming representations. The findings illustrated that interpreting sources of inspiration requires processes such as the use of analogical thinking and abstraction. In addition, creative ideation is a gradual development of ideas. The designer constrains the design situation through creation of visual-material ideas until a suitable idea(s) emerge. The findings encourage viewing design ideation as a multi-modal process in which representations are important triggers for ideation. The exploratory process of generating and transforming representations is a holistic making-related activity that is best supported by interaction with peers and different types of externalization methods. The study proposes two objectives that design tasks in education should address. Firstly, the ideation phase should include deliberate practices and a variety of techniques for manipulating representations to develop visual ideas. Secondly, the ideation process should embed meaning-making for personal engagement and exploration to pursue ideation towards wider contexts of learning.
Vacuum nanoelectronics: Back to the future?—Gate insulated nanoscale vacuum channel transistor

A gate-insulated vacuum channel transistor was fabricated using standard silicon semiconductor processing. Advantages of the vacuum tube and transistor are combined here by nanofabrication. A photoresist ashing technique enabled the nanogap separation of the emitter and the collector, thus allowing operation at less than 10 V. A cut-off frequency fT of 0.46 THz has been obtained. The nanoscale vacuum tubes can provide high frequency/power output while satisfying the metrics of lightness, cost, lifetime, and stability at harsh conditions, and the operation voltage can be decreased comparable to the modern semiconductor devices.
Fluctuations of the Metric Tensor: On Fermion Propagators and on the Cosmological Constant

Conformal fluctuations of the metric tensor are considered. They give rise to a Planck scale size lower bound of the proper length. Infinit ies arising fro m the point-like character of particles are thus avoided, expressions related to fermion propagators are finite without the need to renormalize or regularize. The quark condensate, constituent quark mass, pion mass, and pion weak decay constant are calculated within the SU(2) Nambu--Jona-Lasinio model. The nu merical values are con- sistent with known strong interaction physics if one assumes very small values of the current quark mass and effective coupling constant. The usual values of these quantities in hadron phenomenology can be interpreted as resulting fro m dressing of the very s mall bare quantities with the fluctuations. With respect to the cosmological constant it is shown that a cosmological constant term, wh ich may initially exist in the gravitational action, is "masked" by the fluctuations of the metric, i.e., it does not appear in the final Einstein equation. Instead, the fluctuations give rise to a cosmological constant themselves.
Job Burnout, Stress, and Satisfaction among Emergency Nursing Staff after Health System Transformation Plan in Iran

Introduction: Job burnout, stress, and satisfaction are linked to quality of care, patient outcomes and retention of staff. This study was conducted to determine the mentioned issues among emergency nurses. Methods: This cross-sectional study was conducted on all nurses working in the emergency departments of 10 hospitals in Tehran, Iran, in 2017. Standard questionnaires were used for gathering the data of participants regarding job burnout, stress, and satisfaction. Results: 709 (90%) participants returned the completed questionnaires (58.9% female). The mean age of the nurses was 33 (SD = 7) years. The level of job burnout was moderate in 76.1%, low in 22.5%, and high in 1.4% of the nurses. The level of burnout in the married nursing staff was lower than single nurses (3.78 ± 0.98 versus 4.14 ± 0.58, p = 0.049). The level of job satisfaction was moderate in 61.1%, low in 22.2%, and high in 16.7%. There was a significant correlation between age and job satisfaction (p = 0.027, r = 0.3). Job burnout was directly correlated with job stress (p ≤0.001, r = 0.57) and job burnout was negatively correlated with job satisfaction (p = 0.001, r = -0.41). Conclusion: More than 60% of the studied emergency nurses had moderate levels of job burnout, stress, and satisfaction. Job burnout had a direct correlation with job stress and indirect correlation with job satisfaction. Planning to reduce burnout of the emergency nursing staff seems to be necessary.

Four-wave resonant interactions in the classical quadratic Boussinesq equations

We investigate theoretically the irreversibile energy transfer in flat bottom shallow water waves. Starting from the oldest weakly nonlinear dispersive wave model in shallow water, i.e. the original quadratic Boussinesq equations, and by developing a statistical theory (kinetic equation) of the aforementioned equations, we show that the four-wave resonant interactions are naturally part of the shallow water wave dynamics. These interactions are responsible for a constant flux of energy in the wave spectrum, i.e. an energy cascade towards high wavenumbers, leading to a power law in the wave spectrum of the form of k−3/4. The nonlinear time scale of the interaction is found to be of the order of (h/a)4 wave periods, with a the wave amplitude and h the water depth. We also compare the kinetic equation arising from the Boussinesq equations with the arbitrary-depth Hasselmann equation and show that, in the limit of shallow water, the two equations coincide. It is found that in the narrow band case, both in one-dimensional propagation and in the weakly two-dimensional case, there is no irreversible energy transfer because the coupling coefficient in the kinetic equation turns out to be identically zero on the resonant manifold.

Anomalous temperature evolution of the electronic structure of FeSe

We present angle-resolved photoemission spectroscopy data taken from the structurally simplest representative of iron-based superconductors, FeSe, in a wide temperature range. Apart from the variations related to the nematic transition, we detect very pronounced shifts of the dispersions on the scale of hundreds of degrees Kelvin. Remarkably, upon warming up the sample, the band structure has a tendency to relax to the one predicted by conventional band structure calculations, directly opposite to what is intuitively expected. Our findings shed light on the origin of the dominant interaction shaping the electronic states responsible for high-temperature superconductivity in iron-based materials.
Certificates for system analysis & model predictive control of a switched reluctance motor

The aim of this thesis is twofold. Firstly, mathematical certificates based on convex optimization are used to prove instability of dynamical systems and to certify polynomial nonnegativity. The second aim is to develop a methodology based on model predictive control for the direct torque control of a switched reluctance motor. The first part of this work is devoted to the stability analysis of nonlinear autonomous continuous-time systems. Lyapunov’s second method is one of the most important techniques in the study of stability of dynamical systems. This approach uses a so-called Lyapunov function to establish certain stability properties of a given system. In this work, duality theory from functional analysis is used to derive novel conditions for the nonexistence of such a function to draw conclusions on unstable behavior. The dual space of a Lyapunov function is characterized by Borel measures that satisfy a generalized continuity equation and admit a natural interpretation in terms of flows along the vector field. It is shown that measures corresponding to unstable flows provide certificates for the nonexistence of a Lyapunov function and prove that certain stability properties do not hold. The existence problem of a sum of squares (SOS) Lyapunov function for a system described by a polynomial vector field is considered as a special case. It is shown that analogous to the general case, certificates for nonexistence of such a Lyapunov function are provided by the moments of measures which encode unstable dynamical behavior. The second part of the thesis deals with exact certificates for polynomial nonnegativity. Nonnegativity of a polynomial with rational coefficients is usually verified by computing a sum of squares decomposition using numerical convex optimization solvers. Although the underlying floating point methods in principle allow for numerical approximations of arbitrary precision, the computed solutions will never be exact. However, in many applications such as geometric theorem proving, it is critical to obtain solutions that can be exactly verified. In this work, a numeric-symbolic method is developed that exploits the efficiency of numerical techniques to obtain an approximate solution, which is then used as a starting point for the computation of an exact rational result. It is shown
Box simulations of rotating magnetoconvection - Effects of penetration and turbulent pumping

Various effects of penetration in rotating magnetoconvection are studied by means of three-dimensional numerical simulations employing the code NIRVANA. A local, 2-layer model is applied dividing the computational domain (which is a rectangular box placed tangentially on a sphere at latitude 45°) in an unstable polytropic region on top of a stable polytropic region. Different realizations of convection are examined parameterized by Taylor numbers Ta = {0,6×10 4 ,6×10 5 } and magnetic field strengths β = (5, 50, 500, 5000, ∞}. We find a rather distinctive behavior of the penetration depth Δ on the system parameters (Tα,β). In non-rotating convection A is a monotonically decreasing function of β - 1 which is due to magnetic quenching effects. Also, penetration is subject to rotational quenching, i.e. A is reduced for increasing rotation rate. In the intermediate regime of (Tα, β), the effects of rotation and magnetic field on Δ do not simply add (see Fig. 3). We find, nevertheless, a very strong reduction of the penetration depth of overshooting turbulence by both rotation and magnetism. Penetrative convection is closely associated with the mixing of a passive scalar quantity advected with the flow. In the long term, the tracer material penetrates significantly deeper into the stable layer than suggested by Δ which is due to the cumulative effect of isolated, fast-moving plumes. In case of a weak magnetic field, penetrative convection also serves to ensure a downward transport of magnetic flux by turbulent pumping with an average rate γ z -7 x 10 - 3 measured in units of the sound speed at the top z-boundary. For larger magnetic fields the pumping effect is quenched and even changes sign in the convection zone. This effect is suggested as being due to the effect of "turbulent buoyancy" which in density-stratified media transports a given magnetic field upwards if it is not too strong (Kichatinov & Riidiger 1992).
A high-order Discontinuous Galerkin method for the seismic wave propagation

We are interested in the simulation of P-SV seismic wave propagation by a high-order Discontinuous Galerkin method based on centered fluxes at the interfaces combined with a leap-frog time-integration. This non-diffusive method, previously developed for the Maxwell equations, is particularly well adapted to complex topographies and fault discontinuities in the medium. We prove that the scheme is stable under a CFL type condition and that a discrete energy is preserved on an infinite domain. Convergence properties and efficiency of the method are studied through numerical simulations in two and three dimensions of space.
Qualitative and Quantitative Phytochemical Screening of the Aqueous Leaf Extract of Senna mimosoides : Its Effect in in vivo Leukocyte mobilization induced by inflammatory stimulus

Senna mimosoides formerly known as Cassia mimosoides belongs to the family Caesalpinacea and the genus senna. The leaf is used in folklore medicine for the treatment of oedema and breastmilk toxicity in neonates. The phytochemical analysis and in vivo leukocyte mobilization effect of Senna mimosoides were investigated. For the animal model experiment, a total of twenty five (25) Wistar albino rats of either sex used in in vivo leukocyte mobilization were grouped as follows.Rats in group A (control) were administered 0.2 ml of normal saline; rats in groups B, C and D were treated with 100, 250 and 500 mg/kg of the aqueous extract of S. mimosoides respectively while group E rats received 25 mg/kg of indomethacin a standard drug.The qualitative and quantitative phytochemical parameters carried out showed presence of 2.67 ± 0.0013 mg of flavonoids; 3.43 ± 0.0028 mg of alkaloids; 1.97 ± 0.0030 mg of saponin; 2.32 ± 0.0032 mg of terpenoids; 0.86 ± 0.0023 mg of steroid; 3.61 ± 0.0025 mg of phenol; 8.31 ± 0.0032 mg of reducing sugar; 4.75 ± 0.0034 mg of tannin; 1.61 ± 0.0031 mg of cyanide; 2.75 ± 0.0029 mg of glycoside and 4.68 ± 0.0033 mg of soluble carbohydrates for every 100 g of the extract.The total leukocyte count of the groups treated with different concentrations of extract increased in a dose dependent manner while the group treated with indomethacin decreased significantly (p < 0.05) when compared with control.The result showed that the extract significantly stimulated the mobilization of leukocyte.The findings of this study provide evidence that aqueous extract of this tested plant contains medicinally important bioactive compounds, justifying its use in folklore medicine for the treatment of diseases. It was also deduced from this study that the anti-inflammatory property of the extract is not at the level of leukocyte mobilization. However, the stimulation of leukocyte by the extract suggests that it may play a role in immune response. K ey wo rd s
THE IMPACT OF CAPITAL STRUCTURE AND INTERNAL GOVERNANCE MECHANISMS ON MALAYSIAN MANUFACTURING FIRMS' PERFORMANCE

This study examines the impact of capital structure and internal governance mechanisms on Malaysian manufacturing firms" performance. A total of 183 companies were selected from the list of listed companies in Bursa Malaysia within the year 2007 to 2010. We collect the corporate governance data from the annual financial data from Thompson Reuter"s DataStream. The study shows the positive impact of capital structure on firm performance of manufacturing firms in Malaysia. However, this study found CEO duality and independent director do not affect firm performance. The implication of this study is that the manufacturing firms in Malaysia should achieve optimal capital structure in improving firm performance.
Perceived Maternal Acceptance Rejection And Control On Primary School Children

Parental acceptance is important for children. Children need to receive positive responses from their parents. Based on the literature, children who are neglected by their mothers are more significantly associated with psychological and social maladjustment. On the contrary, if children are accepted by their mothers, this is connected with psychological and social adjustment in their life. This study was conducted to analyze the relationship between perceived maternal acceptance-rejection and control and psychological and social maladjustment in a sample of primary school students residing in a rural community. The main aim was to further understand the mother - child relationship and develop family school cooperation. The participants were a group of 36 primary school students aged between 9 to 11 and their 2 class teachers and a vice chair of the school in Karpaz of Iskele district, North Cyprus. Demographical Information Sheet, Child/Adult: PAR/Control Mother Version Questionnaire and Conners Teacher Evaluation Scale – Revised Long Form was used. The main findings indicated that perceived maternal acceptance mean scores were higher than perceived rejection and control. Perceptions of children maternal rejection were significantly correlated with children psychological and social maladjustment. However, no significant relationships were found between mother’s education, occupation and perceived maternal acceptance, rejection and control and children’s psychological and social maladjustment. The significance of the study and its limitations are discussed.
Questioning local particularities in an era of the suspect mantra of global «excellence» education branding

Ed uc ac ao , S oc ie da de & C ul tu ra s, no 3 7, 2 01 2, 2 344 This study takes a hybrid and deliberately tentative approach to educational research. It incorporates a literary, not social scientific, reading of the verbal analytics of the student teachers that will be the first generation of a potentially radically new and different curriculum in Scotland. They are also the first generation of their (working-class) families to attend university. Through close observation, combined with ethnographic textual analysis, in our empirical-philosophically inclined study we aim to situate these students within a dominant imaginary of a global context and to contest the extent they are personally ready to embrace Bauman’s fluid, mobile world of the 21 century. Given the reluctance of contemporary academia to judge other lifestyles, we aspire to a position of intellectual courage where, by exploring their personal constructions regarding the meanings of their own cultural and leisure pursuits, we necessarily judge. Our purpose is not to label or judge (without justification) but rather interrogate, and potentially celebrate how these student teachers relate to their own – and an imagined wider – world. We believe that the cultural capital inhering in the cultural activities they consume will inevitably condition the school’s hidden curriculum through which a sense of place, socially and geographically speaking, will be conveyed to children. In reassuringly sociological nomenclature, our paper can then be understood as engaging with the subject of the reproduction of society through the mechanism of state schooling affiliating itself with neo-liberal values which are anathema to certain conceptions of education as personal liberation. We are arguing that the education of teachers ought to attend to a greater extent to their inherited «life worlds».
Self- Disclosure Patterns of Newly Married Adults in Oyo Metropolis: Couselling Intervention

This research investigated the self-disclosure patterns of newly married adults in Oyo metropolis using descriptive survey method. Three hundred (300) newly married adults were drawn through purposive sampling technique and a questionnaire tagged Self-disclosure Patterns of Newly Married Adults (QSDPNMA) was used to obtain the data. Two null hypotheses were generated for the purpose of this research and tested using t-test and Analysis of variance statistical tools. The result revealed that there was a significant difference in the self-disclosure patterns of newly married adults in Oyo metropolis based on gender. It was also revealed that there was a significant difference in the self-disclosure patterns of newly married adults based on length of years in marriage and spouse age. However, the hypothesis which states that there was no significant difference in the self-disclosure patterns of newly married adults based on religion was accepted which indicates that religion does not play a significant role in the self –disclosure patterns of newly married adults. Therefore, it was recommended that the newly married adults must be taught about self – disclosure patterns that promote healthy relationships. Also, religious organizations should always invite professionals in the field of marriage counseling to sensitize the members of their religious organizations about the importance of self – disclosure in marriage.
