The effects of protection on the growth rate and on the need for external assistance
Host studies of protection in developing countries are concerned
with questions of static losses of real output or inefficient resource
allocation at some point of time. These studies are often criticised as
not relevant to problems of development. This paper incorporates the effects
of protection into the most widely used macro—economic projection model,
the 'two—gap' model of Chenory and Strout, and examines some dynamic implications
of protection.
The adaptation of the two-gap model explicitly allows for two
facts related to protection:
1) The apparent amount of import substitution or foreign
exchange saving, overstates the actual, import saving
if the new industry is protected.
2) The apparent amount of export growth or new foreign
exchango earned, is understated whenever protection
applies only to import substitutes.
Thus, the presence of protection will cause the usual macroeconomic
projection models to understate import demand whenever conventional
definitions of value added are used, if there is emphasis on
import substitution behind protection in the plan period.
The adaptation to the model makes it qui+e clear why oountries
pursuing industrialization by means of protection often run into balance
of payments difficulties; The factor payments generated in import—substituting
industries cxceed the value of foreign exchange saved in the
industry - sometimes by substantial amounts. For countries like Kenya,
Uganda and Tanzania with a high marginal propensity to import, and for
industries &s highly protected as come of the largo establishments in
East Africa, it is quite possible for an investment in import substitution
to produce a deterioration, rather than an improvement, in the balance
of payments.
The paper also explores the implications of protection for the
"requirements" of foreign assistance to sustain a given development
programs The results show that, because protection to industries in fact
results in less balance of payments improvement than it appears to, the
need for foreign assistance will be greater (i.e. the balance of payments
constraint is more severe) the greater is the reliance on protection to
"encourage" growth

Participants’ Experiences in Heutagogy Teacher Professional Education in Indonesia
This study investigated a heutagogy-informed teacher professional education model designed to assist Indonesian teachers in achieving the competencies established by the Indonesian government to address teacher quality issues. The critical concepts of the model include self-determined learning, metacognitive reflection, collaborative learning, and capability development. An embedded design methodology, grounded in pragmatism as the overarching research paradigm, was employed for this investigation. The findings of this study provide significant insights for enhancing teachers’ professional education in Indonesia, particularly in terms of the effectiveness of heutagogy-informed approaches compared to traditional approaches of teacher training, with additional benefits stemming from heutagogy-informed, technology-facilitated learning impacting both their professional development and intended classroom practices
Diamond electro-optomechanical resonators integrated in nanophotonic circuits
Diamond integrated photonic devices are promising candidates for emerging
applications in nanophotonics and quantum optics. Here we demonstrate active
modulation of diamond nanophotonic circuits by exploiting mechanical degrees of
freedom in free-standing diamond electro-optomechanical resonators. We obtain
high quality factors up to 9600, allowing us to read out the driven
nanomechanical response with integrated optical interferometers with high
sensitivity. We are able to excite higher order mechanical modes up to 115 MHz
and observe the nanomechanical response also under ambient conditions.Comment: 15 pages, 4 figure
High-Q optomechanical circuits made from polished nanocrystalline diamond thin films
We demonstrate integrated optomechanical circuits with high mechanical
quality factors prepared from nanocrystalline diamond thin films. Using
chemomechanical polishing, the RMS surface roughness of as grown
polycrystalline diamond films is reduced below 3nm to allow for the fabrication
of high-quality nanophotonic circuits. By integrating free-standing
nanomechanical resonators into integrated optical devices, efficient read-out
of the thermomechanical motion of diamond resonators is achieved with on-chip
Mach-Zehnder interferometers. Mechanical quality factors up to 28,800 are
measured for four-fold clamped optomechanical resonators coupled to the
evanescent near-field of nanophotonic waveguides. Our platform holds promise
for large-scale integration of optomechanical circuits for on-chip metrology
and sensing applications
