The Strategic Adaptation of Chinese-Manadonese in the Reform Era
This article is a further discussion of previous research which is a pilot project to observe patterns of cultural interaction within the Chinese community in Indonesia as a part of a project to understand the phenomenon of the multicultural society during the New Order Era. The specific target of this research is to study the socio-cultural interactions within the Chinese community in Manado during the Reform Era (2000-2014). This research aims to study the strategic adaptation of the Chinese in Manado, by analysing the obstacles and opportunities in their socio-cultural interaction with the locals. Using data from field research and literature studies, this qualitative research applies an ethnographic approach by observing various actions in their socio-cultural interactions

Berry phase in generalized chiral
We consider the generalized chiral on with a gauge field
coupled with different charges to both chiral components of a fermionic field.
Using the adiabatic approximation we calculate the Berry phase and the
corresponding connection and curvature for the vacuum and many
particle Fock states. We show that the nonvanishing vacuum Berry phase is
associated with a projective representation of the local gauge symmetry group
and contributes to the effective action of the model.Comment: LATEX file, 17 pages; extended version of a talk given at Int.

Relativistic two-body system in (1+1)-dimensions
The relativistic two-body system in (1+1)-dimensional quantum electrodynamics
is studied. It is proved that the eigenvalue problem for the two-body
Hamiltonian without the self-interaction terms reduces to the problem of
solving an one-dimensional stationary Schr\"odinger type equation with an
energy-dependent effective potential which includes the delta-functional and
inverted oscillator parts. The conditions determining the metastable energy
spectrum are derived, and the energies and widths of the metastable levels are
estimated in the limit of large particle masses. The effects of the
self-interaction are discussed.Comment: LATEX file, 21 pp., 4 figure
Persepsi politik belia India di Institusi Pengajian Tinggi Awam (IPTA) (Political perception of Indian youths in Malaysia’s public higher learning institutions)
Sokongan kaum India, khususnya belia terhadap MIC (Malaysian Indian Congres) dikatakan kian merosot.
MIC tidak lagi relevan sebagai parti yang mewakili masyarakat India seperti yang dibuktikan dalam Pilihan
Raya Umum (PRU) ke-12, 2008, majoriti calonnya tewas . Artikel ini berttujuan untuk mengkaji persepsi politik
belia India di Institusi Pengajian Tinggi Awam (IPTA). Kajian ini melibatkan 150 orang pelajar India dari tiga
buah universiti awam, iaitu UKM, UPM dan UM. Berdasarkan kaji selidik dan pemerhatian, dapatan kajian
menunjukkan kebanyakan belia India IPTA masih menyokong BN, namun mereka mahukan isu-isu penting
dalam masyarakat India iaitu isu pendidikan di sekolah Tamil, pemberian biasiswa, isu kuota, isu agama dan isu
sosioekonomi diselesaikan oleh kepemimpinan MIC sebaiknya. Mereka juga melayari laman web untuk
mendapatkan maklumat politik terkini dan memilih calon yang mempunyai karisma atau ketokohan, kelayakan
akademik yang tinggi dan calon muda serta parti politik yang memperjuangkan isu kemanusiaan seperti
ketelusan, keadilan, hak asasi manusia, anti rasuah; memperjuangkan isu alam sekitar. Majoriti belia India IPTA
akan memilih MIC dan BN sebagai parti politik mereka dalam PRU ke-13 jika parti tersebut lebih proaktif
dalam menangani isu yang dihadapi oleh masyarakat India di Malaysia. Belia India IPTA juga menyatakan
hanya MIC yang dapat memperjuangkan hak kaum India dan mereka juga menjangkakan BN akan terus menang
dalam PRU akan datang
Spin operator and spin states in Galilean covariant Fermi field theories
Spin degrees of freedom of the Galilean covariant Dirac field in (4+1)
dimensions and its nonrelativistic counterpart in (3+1) dimensions are
examined. Two standard choices of spin operator, the Galilean covariant and
Dirac spin operators, are considered. It is shown that the Dirac spin of the
Galilean covariant Dirac field in (4+1) dimensions is not conserved, and the
role of non-Galilean boosts in its nonconservation is stressed out. After
reduction to (3+1) dimensions the Dirac field turns into a nonrelativistic
Fermi field with a conserved Dirac spin. A generalized form of the Levy-Leblond
equations for the Fermi field is given. One-particle spin states are
constructed. A particle-antiparticle system is discussed.Comment: Minor corrections in the text; journal versio
Parallelizing Deadlock Resolution in Symbolic Synthesis of Distributed Programs
Previous work has shown that there are two major complexity barriers in the
synthesis of fault-tolerant distributed programs: (1) generation of fault-span,
the set of states reachable in the presence of faults, and (2) resolving
deadlock states, from where the program has no outgoing transitions. Of these,
the former closely resembles with model checking and, hence, techniques for
efficient verification are directly applicable to it. Hence, we focus on
expediting the latter with the use of multi-core technology.
We present two approaches for parallelization by considering different design
choices. The first approach is based on the computation of equivalence classes
of program transitions (called group computation) that are needed due to the
issue of distribution (i.e., inability of processes to atomically read and
write all program variables). We show that in most cases the speedup of this
approach is close to the ideal speedup and in some cases it is superlinear. The
second approach uses traditional technique of partitioning deadlock states
among multiple threads. However, our experiments show that the speedup for this
approach is small. Consequently, our analysis demonstrates that a simple
approach of parallelizing the group computation is likely to be the effective
method for using multi-core computing in the context of deadlock resolution
Generalised chiral QED2 : Anomaly and Exotic Statistics
We study the influence of the anomaly on the physical quantum picture of the
generalized chiral Schwinger model defined on the circle. We show that the
anomaly i) results in the background linearly rising electric field and ii)
makes the spectrum of the physical Hamiltonian nonrelativistic without a
massive boson. The physical matter fields acquire exotic statistics . We
construct explicitly the algebra of the Poincare generators and show that it
differs from the Poincare one. We exhibit the role of the vacuum Berry phase in
the failure of the Poincare algebra to close. We prove that, in spite of the
background electric field, such phenomenon as the total screening of external
charges characteristic for the standard Schwinger model takes place in the
generalized chiral Schwinger model, too.Comment: LATEX file, 36 pp., to appear in Phys.Rev.
An Analysis of the Impact of Boko Haram insurgents on Business Entrepreneurship Environment in Nigeria
This paper will examine the impact of boko haram on business entrepreneurship environment in Nigeria. Since the emergence of the group in 2002, the business environment has not been conducive for business related activities due to bombings and attacks on the people. An exploratory method of data collection was carried out using secondary data such as news papers, journals and online information. the findings revealed that businesses no longer takes place in the affected areas such as the northeast part of Nigeria because markets were closed, banking services not rendered or hours of services reduced. The paper then recommends that the source of income; training; and supply of weapons to Boko Haram be blocked by the Nigerian government and also engage in human security such as job creation; and provision of infrastructural facilities so as to combat the activities of the sect and thereby creating enabling environment for business and entrepreneurship to flourish.
