Penelitian ini bertujuan untuk mengetahui perbedaan persepsi terhadap pengembangan karir antara wanita menikah dan wanita belum menikah (single). Penelitian ini melibatkan 80 orang wanita bekerja yang dibagi menjadi dua kriteria yaitu wanita menikah dan wanita belum menikah (single). Metode pengambilan sampel dilakukan dengan teknik incidental sampling. Alat ukur yang digunakan dalam penelitian ini adalah skala persepsi pengembangan karir berdasarkan teori Davis & Werther (1996) yang terdiri dari aspek-aspek perlakuan yang adil dalam berkarir, kepedulian atasan langsung, informasi berbagai peluang promosi, minat untuk dipromosikan dan kepuasan karir. Hasil analisa data penelitian menunjukan tidak adanya perbedaan terhadap persepsi pengembangan karir antara wanita menikah dan belum menikah (single)
Use of biorational insecticides for the control of Tuta absoluta (Meyrick) infestations on open field tomato
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), the tomato leaf miner, is
one of the most devastating pests affecting tomato crops in Italy. Management
of T. absoluta was assessed in open-field tests using three biorational insecticides,
Azadirachtin, Bacillus thuringiensis var. kurstaki, and Beauveria
bassiana, and a combination of three synthetic insecticides, Emamectin, Indoxacarb
and Metaflumizone, as a control treatment. Our results showed that
only the combination of Azadirachtin \u2013 B. thuringiensis was able to reduce the
impact of tomato leaf miner on the fruit\u2019s marketable production similarly to
the control treatment. This finding suggests that biorational insecticides are a
good alternative to synthetic ones. Possible use of biorational insecticides in
the management of tomato leaf miner in organic farming system is discussed
Newly Discovered RR Lyrae Stars in the SDSSXPanXSTARRS1XCatalina Footprint
We present the detection of 6,371 RR Lyrae (RRL) stars distributed across
~14,000 deg^2 of the sky from the combined data of the Sloan Digital Sky Survey
(SDSS), the Panoramic Survey Telescope and Rapid Response System 1 (PS1), and
the second photometric catalogue from the Catalina Survey (CSDR2), out of
these, ~2,021 RRL stars (~572 RRab and 1,449 RRc) are new discoveries. The RRL
stars have heliocentric distances in the 4--28 kpc distance range. RRL-like
color cuts from the SDSS and variability cuts from the PS1 are used to cull our
candidate list. We then use the CSDR2 multi-epoch data to refine our sample.
Periods were measured using the Analysis of Variance technique while the
classification process is performed with the Template Fitting Method in
addition to the visual inspection of the light curves. A cross-match of our RRL
star discoveries with previous published catalogs of RRL stars yield
completeness levels of ~50% for both RRab and RRc stars, and an efficiency of
~99% and ~87% for RRab and RRc stars, respectively. We show that our method for
selecting RRL stars allows us to recover halo structures. The full lists of all
the RRL stars are made publicly available.Comment: 14 pages, 11 figures. Accepted 2014 March 30. Received 2014 March 12;

The (Z_2)^3 symmetry of the non-tri-bimaximal pattern for the neutrino mass matrix
In view of the recent neutrino oscillation data pointing to a non-vanishing
value for the smallest mixing angle (), we derive and find explicit
realizations of the flavor symmetry which characterizes, for the
neutrino mass matrix, uniquely a variant of the tripartite form, originally
conceived to lead to the tri-bimaximal mixing with , so that to
allow now for a non-tri-bimaximal pattern with non-zero . We impose
this flavor symmetry in a setting including the charged leptons and we see that
it can make room, through higher order terms involving new SM-singlet scalars,
for the mass hierarchy of charged leptons. Moreover, within type-I seesaw
mechanism augmented with the flavor symmetry, certain patterns occurring in
both the Dirac and the Majorana neutrino mass matrices can accommodate all
types of mass hierarchies in the effective neutrino mass matrix, but no
lepton/baryon asymmetry can be generated. Finally, we discuss how type-II
seesaw mechanism, when supplemented with the flavor symmetry, could be used to
interpret the observed baryon asymmetry through leptogenesis.Comment: 14 pages, 1 table, added references, version to appear in PRD. arXiv

Costs analysis of a population level rabies control programme in Tamil Nadu, India
The study aimed to determine costs to the state government of implementing different interventions for controlling rabies among the entire human and animal populations of Tamil Nadu. This built upon an earlier assessment of Tamil Nadu’s efforts to control rabies. Anti-rabies vaccines were made available at all health facilities. Costs were estimated for five different combinations of animal and human interventions using an activity-based costing approach from the provider perspective. Disease and population data were sourced from the state surveillance data, human census and livestock census. Program costs were extrapolated from official documents. All capital costs were depreciated to estimate annualized costs. All costs were inflated to 2012 Rupees. Sensitivity analysis was conducted across all major cost centres to assess their relative impact on program costs. It was found that the annual costs of providing Anti-rabies vaccine alone and in combination with Immunoglobulins was \$0.7 million (Rs 36 million) and \$2.2 million (Rs 119 million), respectively. For animal sector interventions, the annualised costs of rolling out surgical sterilisation-immunization, injectable immunization and oral immunizations were estimated to be \$ 44 million (Rs 2,350 million), \$23 million (Rs 1,230 million) and \$ 11 million (Rs 590 million), respectively. Dog bite incidence, health systems coverage and cost of rabies biologicals were found to be important drivers of costs for human interventions. For the animal sector interventions, the size of dog catching team, dog population and vaccine costs were found to be driving the costs. Rabies control in Tamil Nadu seems a costly proposition the way it is currently structured. Policy makers in Tamil Nadu and other similar settings should consider the long-term financial sustainability before embarking upon a state or nation-wide rabies control programme
Theory of unitarity bounds and low energy form factors
We present a general formalism for deriving bounds on the shape parameters of
the weak and electromagnetic form factors using as input correlators calculated
from perturbative QCD, and exploiting analyticity and unitarity. The values
resulting from the symmetries of QCD at low energies or from lattice
calculations at special points inside the analyticity domain can beincluded in
an exact way. We write down the general solution of the corresponding Meiman
problem for an arbitrary number of interior constraints and the integral
equations that allow one to include the phase of the form factor along a part
of the unitarity cut. A formalism that includes the phase and some information
on the modulus along a part of the cut is also given. For illustration we
present constraints on the slope and curvature of the K_l3 scalar form factor
and discuss our findings in some detail. The techniques are useful for checking
the consistency of various inputs and for controlling the parameterizations of
the form factors entering precision predictions in flavor physics.Comment: 11 pages latex using EPJ style files, 5 figures; v2 is version

The neonatal outcomes of Dexamethasone administration before scheduled cesarean delivery at term: a randomized clinical trial
Background: Caesarean delivery (CD) rates in developing countries are rising beyond the recommended rates of World health organization. Objective of this study was to evaluate whether Dexamethasone injections reduce neonatal incubation admissions when given before scheduled caesarean delivery (CD) at term or not.Methods: A double blinded, two armed, randomized clinical trial was conducted at Tanta University hospitals in the period from October 2017 to March 2019. Four hundred pregnant women admitted for scheduled CD with gestational age ≥37 weeks were included. Patients were randomized into study group and control group. The study group was given 3 dexamethasone doses, 8 mg each while control group was given saline injections simultaneously as a placebo drug. The primary outcome was the neonatal incubatory admissions.Results: Demographic data in both groups were comparable. Transient tachypnea of newborn (TTN) was 15.47% in study group versus 20.33% in control group with p=0.227. The respiratory distress (RDS) in study group was 6.63% versus 9.89% in control group with p=0.260. The incubation admissions were nasal oxygen 12.71% versus 15.38%, continuous positive airway pressure ventilation (CPAP) 5.52% versus 8.24% and mechanical ventilation was 3.87% versus 6.59% in the study and control groups respectively.Conclusions: Although Dexamethasone administration before scheduled CD at term reduced both respiratory morbidity and incubation admissions, the differences between study and control groups were not significant
An Efficient In Vitro Propagation Protocol of Cocoyam [Xanthosoma sagittifolium (L) Schott]
Sprouted corm sections of “South Dade” white cocoyam were potted and maintained in a greenhouse for 8 weeks. Shoot tips of 3–5 mm comprising the apical meristem with 4–6 leaf primordial, and approximately 0.5 mm of corm tissue at the base. These explants were treated to be used into the culture medium. A modified Gamborg's B5 mineral salts supplemented with 0.05 μM 1-naphthaleneacetic acid (NAA) were used throughout the study. Thidiazuron (TDZ) solution containing 0.01% dimethyl sulfoxide (DMSO) was used. Erlenmeyer flasks and test tubes were used for growing cultures. The effect of different media substrate, thidiazuron, and the interaction between TDZ and Benzylaminopurine (BAP) on cocoyam culture were tested. Results indicated that cocoyam can be successfully micropropagated in vitro through various procedures. All concentrations tested (5–20 μM BAP and 1–4 μM TDZ) produced more axillary shoots per shoot tip than the control without cytokinins. Greater proliferation rates were obtained through the use of 20 μM BAP and 2 μM TDZ, respectively, 12 weeks from initiation. Shoots produced with BAP were larger and more normal in appearance than those produced with TDZ, which were small, compressed, and stunted. The use of stationary liquid media is recommended for economic reasons
