Caring for a spouse with dementia : a literature review and exploratory study of carers' experience of their marital relationship
This thesis comprises three main sections. The first is a literature review on
the influence of marital relationship on the experience of spouse carers of
people with dementia. Due to methodological weaknesses findings need to be
interpreted with caution, however, the research suggests that positive premorbid
and concurrent relationships are indicative of greater wellbeing in
spouse carers, and also that dementia impacts negatively on marital
relationship. Implications for clinical practice and ideas for future research are
explored.
Section Two is a report on a study exploring spouse carers' experience of their
marital relationship whilst caring for a husband or wife with severe dementia.
Ten spouse carers (six wives and four husbands) of people suffering from
severe dementia participated in a semi-structured interview which was
transcribed and analysed in accordance with Interpretative Phenomenological
Analysis (IPA) methodology. Five interrelated processes with 19 sub-themes
were identified; Establishing connections and forming a lasting relationship,
Experiencing dementia as a threat to the relationship, Attempting to maintain
the existence of a relationship, Desire to care and Experiencing the impact of
caring on wellbeing. Implications for clinical practice and further research are
discussed.The third section provides a critical appraisal of the research process and
includes an exposition of key lessons learnt, future Continuing Professional
Development needs and personal reflections on future functioning as a
researcher within the role of a Clinical Psychologist
Perancangan Komunikasi Visual Objek Wisata Alam Banyuwangi
Banyuwangi merupakan kota yang terletak di ujung paling Timur kepulauan Jawa. Oleh karena ituBanyuwangi mendapatkan julukan sebagai Sunrise of Java. Selama beberapa tahun terakhir perkembanganpariwisata pada kota ini sudah cukup bagus. Namun kurangnya media promosi menjadikan Banyuwangisebagai kota persinggahan bagi wisatawan yang hendak ke Pulau Bali melalui jalur darat. Oleh karena itudiperlukan sarana promosi untuk menarik para wisatawan berlibur pada di Kota Banyuwangi dan tidak lagimenjadikan Banyuwangi sebagai kota persinggahan saja
New concept of relativistic invariance in NC space-time: twisted Poincar\'e symmetry and its implications
We present a systematic framework for noncommutative (NC) QFT within the new
concept of relativistic invariance based on the notion of twisted Poincar\'e
symmetry (with all 10 generators), as proposed in ref. [7]. This allows to
formulate and investigate all fundamental issues of relativistic QFT and offers
a firm frame for the classification of particles according to the
representation theory of the twisted Poincar\'e symmetry and as a result for
the NC versions of CPT and spin-statistics theorems, among others, discussed
earlier in the literature. As a further application of this new concept of
relativism we prove the NC analog of Haag's theorem.Comment: 15 page
Transport Equations from Liouville Equations for Fractional Systems
We consider dynamical systems that are described by fractional power of
coordinates and momenta. The fractional powers can be considered as a
convenient way to describe systems in the fractional dimension space. For the
usual space the fractional systems are non-Hamiltonian. Generalized transport
equation is derived from Liouville and Bogoliubov equations for fractional
systems. Fractional generalization of average values and reduced distribution
functions are defined. Hydrodynamic equations for fractional systems are
derived from the generalized transport equation.Comment: 11 pages, LaTe
On "full" twisted Poincare' symmetry and QFT on Moyal-Weyl spaces
We explore some general consequences of a proper, full enforcement of the
"twisted Poincare'" covariance of Chaichian et al. [14], Wess [50], Koch et al.
[34], Oeckl [41] upon many-particle quantum mechanics and field quantization on
a Moyal-Weyl noncommutative space(time). This entails the associated braided
tensor product with an involutive braiding (or -tensor product in the
parlance of Aschieri et al. [3,4]) prescription for any coordinates pair of
generating two different copies of the space(time); the associated
nontrivial commutation relations between them imply that is central and
its Poincar\'e transformation properties remain undeformed. As a consequence,
in QFT (even with space-time noncommutativity) one can reproduce notions (like
space-like separation, time- and normal-ordering, Wightman or Green's
functions, etc), impose constraints (Wightman axioms), and construct free or
interacting theories which essentially coincide with the undeformed ones, since
the only observable quantities involve coordinate differences. In other words,
one may thus well realize QM and QFT's where the effect of space(time)
noncommutativity amounts to a practically unobservable common noncommutative
translation of all reference frames.Comment: Latex file, 24 pages. Final version to appear in PR
Research in technology education: Looking back to move forward
This paper attempts to summarize the focus of the research that has recently taken place in Technology Education, and from that basis suggest a trajectory for future research trends. Some research that is considered particularly seminal to the profession is summarised, and the paper is concluded with some reflections about personal research agendas
Deterministic constant-temperature dynamics for dissipative quantum systems
A novel method is introduced in order to treat the dissipative dynamics of
quantum systems interacting with a bath of classical degrees of freedom. The
method is based upon an extension of the Nos\`e-Hoover chain (constant
temperature) dynamics to quantum-classical systems. Both adiabatic and
nonadiabatic numerical calculations on the relaxation dynamics of the
spin-boson model show that the quantum-classical Nos\`e-Hoover chain dynamics
represents the thermal noise of the bath in an accurate and simple way.
Numerical comparisons, both with the constant energy calculation and with the
quantum-classical Brownian motion treatment of the bath, show that the
quantum-classical Nos\`e-Hoover Chain dynamics can be used to introduce
dissipation in the evolution of a quantum subsystem even with just one degree
of freedom for the bath. The algorithm can be computationally advantageous in
modeling, within computer simulation, the dynamics of a quantum subsystem
interacting with complex molecular environments.Comment: Revised versio
Fractional Liouville and BBGKI Equations
We consider the fractional generalizations of Liouville equation. The
normalization condition, phase volume, and average values are generalized for
fractional case.The interpretation of fractional analog of phase space as a
space with fractal dimension and as a space with fractional measure are
discussed. The fractional analogs of the Hamiltonian systems are considered as
a special class of non-Hamiltonian systems. The fractional generalization of
the reduced distribution functions are suggested. The fractional analogs of the
BBGKI equations are derived from the fractional Liouville equation.Comment: 20 page
