Exact formula to relate optical path differences and transversal aberration components
Authors: Cordero-Dávila Alberto , Reyes-Olguín Diego Gabriel , González-García Jorge
Published: February 2023

An exact equation to relate the optical path differences (OPD) with its transversal aberration components (TAC) is determined. The OPD-TAC equation reproduces the Rayces formula and introduces the coefficient for the longitudinal aberration. The defocus orthonormal Zernike polynomial (ZDF) is not a solution for the OPD-TAC equation since the obtained longitudinal defocus depends on the ray height on the exit pupil, meaning that it cannot be interpreted as a defocus. In order to find an exact expression for OPD defocus, first, a general relationship between the wavefront shape and its OPD is established. Second, an exact formula for the defocus OPD is established. Finally, it is proved that only the exact defocus OPD is an exact solution of the exact OPD-TAC equation.
Cascading auto-regressive exponential smoothing of image sequences for reducing turbulence induced motion
Authors: Potvin Guy , McGaughey Donald
Published: February 2023

Atmospheric turbulence can significantly degrade images taken over a long horizontal path near the ground. This can hinder the identification of objects in a scene. We consequently introduce the Cascading Auto-Regressive Exponential Smoothing (CARES) algorithm, which is a fast real-time algorithm that suppresses the effects of atmospheric turbulence in image sequences. CARES is a spatial/temporal filtering algorithm that decomposes the image into a Laplacian Image Pyramid (LIP). Each component of the LIP represents the image smoothed to a specific length scale, which is then temporally filtered using an Auto-Regressive Exponential Smoothing (ARES) filter. The ARES filters have a cut-off frequency that are adjusted in such a way for each LIP component to define a critical velocity. Objects in the scene moving below the critical velocity pass through the CARES filter with little distortion or delay. We assess the performance of CARES using turbulent imaging data. We find that CARES improves image quality using a variety of image quality metrics. We use a simple CARES simulation to show that the salient features of a moving object lag behind by one pixel or less.

Published: February 2023

In this theoretical-experimental study, we use the Fresnel-Kirchhoff diffraction theory to simulate the formation of the far-field diffraction pattern of a divergent Gaussian beam propagated through a BGO photorefractive crystal. We show that for the BGO photorefractive crystal, in addition to the wavefront curvature and the change in the refractive index of the medium due to the light intensity, there is a third contribution affecting the medium-induced nonlinear phase shift; the latter is related to the additional change in the refractive index produced by the photorefractive effect.

Published: February 2023

High-performance integrated spectrometers are highly desirable for many applications ranging from mobile phones to space probes. Based on silicon photonic integrated circuit technology, we propose and demonstrate an on-chip speckle spectrometer consisting of a 15 ×15, two-dimensional (2D), disordered microring lattice. The proposed 2D, disordered microring lattice is simulated by the transfer-matrix method. The fabricated device features a spectral resolution better than 15 pm and an operating bandwidth larger than 40 nm. We also demonstrate that, based on the speckle patterns, our device can perform a spectrum classification using machine learning algorithms, which will have a huge potential in fast, intelligent material and chemical analysis.
Domain effects on the electro-optic properties of thin-film Barium Titanate
Authors: Vasudevan Anupama , Selvaraja Shankar Kumar
Published: February 2023

Thin-film ferroelectric oxide materials over the year have been explored for various electronic applications. Recently, the electro-optic properties of these materials have gained considerable interest as an integrated high-speed electro-optic modulator. Particularly, bulk Barium Titanate has the highest electro-optic response. However, the effect of thin film, domain orientation, and polling on the electro-optic response is not well understood. In this article, we present the domain effects of thin-film ferroelectric Barium Titanate on the electro-optic response in a waveguide configuration. We also show the impact of drive electrode orientation with respect to the in-plane polarisation angle in a multi-domain structure.

Published: February 2023

Optics in the mid-wave-infra-red (MWIR) band are generally heavy, thick and expensive. Here, we demonstrate multi-level diffractive lenses; one designed using inverse design approaches and another using the conventional propagation phase (the Fresnel zone plate or FZP) with diameter = 25um and focal length = 25um operating at $\lambda=4\thinspace\mu$m. We fabricated the lenses by optical lithography and characterized their performance. We show that the inverse-designed MDL achieves larger depth-of-focus and better off-axis performance when compared to the the FZP at the expense of larger spot size and reduced focusing efficiencies. Both lenses are flat with thickness <=0.5mm and weigh <= 3.63g, which are far smaller than their conventional refractive counterparts.
Snapshot High Dynamic Range Imaging Based on Adjustable Attenuation Microarray Mask
Authors: Wenwenjing Zhang , Cao Yu , Zhao Lishuang , yang shuwei , Ma Xinyu
Published: February 2023

High Dynamic Range Imaging Based on Attenuation Microarray Mask has broad application prospects due to its good real-time performance and small size. But at the current level of craftsmanship, it is hard to fabricate a micro-attenuation array mask whose attenuation rate is adjustable. This leads to the fact that the imaging dynamic range cannot adapt to changes in scene brightness in most cases. To this end, this paper proposes a novel imaging system where the dynamic range can be adaptively changed according to the brightness of the scene. The core components are the micro polarization array mask mounted on the CMOS surface and the on-sensor rotatable linear polarizer in front of the lens. By controlling the rotation angle of the polarizer placed before the lens, the CMOS pixel exposure can be precisely controlled. Therefore, the imaging system dynamic range can be adjusted adaptively according to the scene brightness. The experimental results show that the imaging performance remains consistently good even when the dynamic range of the scene is large. By rotating the polarizer in front of the lens to a specific angle, the high dynamic imaging of the scene can be significantly improved.

Chip-based, single-frequency and low phase-noise integrated
photonic laser diodes emitting in the violet
(412 nm) and blue (461 nm) regime are demonstrated.
The GaN-based edge-emitting laser diodes were coupled
to high-Q on-chip micro-resonators for optical
feedback and mode selection resulting in laser self-injection
locking with narrow emission linewidth. Multiple
group III-nitride (III-N) based photonic integrated
circuit chips with different waveguide designs including
single-crystalline AlN, AlGaN, and GaN were developed
and characterized. Single-frequency laser operation
was demonstrated for all studied waveguide
core materials. The best side-mode suppression ratio
was determined to be ∼36 dB at 412 nm with a
single-frequency laser emission linewidth of only about
3.8 MHz at 461 nm. The performance metrics of this
novel type of laser suggest potential implementation in
next generation, portable quantum systems.
Continuous variable quantum conference network with a Greenberger–Horne–Zeilinger entangled state
Authors: Qin Yue , Ma Jingxu , Zhao Di , Cheng Jialin , Yan Zhihui , Jia Xiaojun
Published: February 2023

Quantum conference (QC) is a cryptographic task in secure communications that involves more than two users wishing to establish identical secret keys among N users. The Greenberger–Horne–Zeilinger (GHZ) entangled state is the basic resource for quantum cryptographic communication due to the existence of multipartite quantum correlations. An unconditional and efficient quantum network can be established with a continuous variable (CV) GHZ entangled state because of its deterministic entanglement. Here, we report an implementation of QC scheme using a CV multipartite GHZ entangled state. The submodes of a quadripartite GHZ entangled state are distributed to four spatially separated users. The proposed QC scheme is proved to be secure even when the entanglement is distributed through lossy quantum channels and the collective Gaussian attacks are in the all lossy channels. The presented QC scheme has the capability to be directly extended to a larger scale quantum network by using entangled states with more submodes.

Anterior chamber depth (ACD) is a major risk factor of angle closure disease, and has been used in angle closure screening in various populations. However, ACD is measured from ocular biometer or anterior segment optical coherence tomography (AS-OCT), which are costly and may not be readily available in primary care and community settings. Thus, this proof-of-concept study aims to predict ACD from low-cost anterior segment photographs (ASPs) using deep-learning (DL). We included 2,311 pairs of ASPs and ACD measurements for algorithm development and validation, and 380 pairs for algorithm testing. We captured ASPs with a digital camera mounted on a slit-lamp biomicroscope. Anterior chamber depth was measured with ocular biometer (IOLMaster700 or Lenstar LS9000) in data used for algorithm development and validation, and with AS-OCT (Visante) in data used for testing. The DL algorithm was modified from the ResNet-50 architecture, and assessed using mean absolute error (MAE), coefficient-of-determination (R2), Bland-Altman plot and intraclass correlation coefficients (ICC). In validation, our algorithm predicted ACD with a MAE (standard deviation) of 0.18 (0.14) mm; R2 = 0.63. The MAE of predicted ACD was 0.18 (0.14) mm in eyes with open angles and 0.19 (0.14) mm in eyes with angle closure. The ICC between actual and predicted ACD measurements was 0.81 (95% CI 0.77, 0.84). In testing, our algorithm predicted ACD with a MAE of 0.23 (0.18) mm; R2 = 0.37. Saliency maps highlighted the pupil and its margin as the main structures used in ACD prediction. This study demonstrates the possibility of predicting ACD from ASPs via DL. This algorithm mimics an ocular biometer in making its prediction, and provides a foundation to predict other quantitative measurements that are relevant to angle closure screening.
Automatic meter classification of Kurdish poems
Authors: Mahmudi Aso , Veisi Hadi
Published: February 2023

Most of the classic texts in Kurdish literature are poems. Knowing the meter of the poems is helpful for correct reading, a better understanding of the meaning, and avoiding ambiguity. This paper presents a rule-based method for the automatic classification of the poem meter for the Central Kurdish language also known as Sorani. The metrical system of Kurdish poetry is divided into three classes quantitative, syllabic, and free verses. As the vowel length is not phonemic in the language, there are uncertainties in syllable weight and meter identification. The proposed method generates all the possible situations and then, by considering all lines of the input poem and the common meter patterns of Kurdish poetry, identifies the most probable meter type and pattern of the input poem. Evaluation of the method on a dataset from VejinBooks Kurdish corpus resulted in 97.3% of precision in meter type and 96.2% of precision in pattern identification.
Modifying Deutsch’s scale illusion for application in music
Authors: Ichimiya Issei , Ichimiya Hiroko
Published: February 2023

Deutsch’s scale illusion demonstrates that the overall pitch range is the preferred organization when in competition with both local (note-to-note) pitch proximity and laterality (differences in the input ear). Such intricate factors can make it difficult to mimic this illusion. If a note is under a condition in which grouping by the overall pitch range and the local pitch proximity do not conflict, we hypothesized that an illusion would be perceived simply as the result of the competition between pitch proximity and laterality. In this paper, we aimed to replicate such a condition by modifying Deutsch’s scale illusion. Psychophysical studies were conducted with healthy subjects. In the first half of the study, the C major scale with successive tones was presented in ascending form, alternating between the right and left ears; counterpart notes were simultaneously presented to the opposite ear, and the subjects were asked to listen to these dichotic tone patterns. Several counterpart notes were applied; we found that when the sequences of counterpart notes were close in note-to-note pitch proximity and were not overlapped with the ascending scale in pitch, the subjects appeared to perceive the scale clearly. In the latter half of the study, we applied this condition in music and devised auditory illusions such that melodies of the passages of "Lightly Row," "Cherry Blossoms," and "Jingle Bells" were perceived by listening to "jagged" dichotic tone patterns. The method we described in this paper is simple, and it is possible to easily create auditory illusions in music by applying our method.
De la modernidad a la reacción. Josep Maria Tallada, economía y política (1884-1946).
Authors: Lo Cascio Paola
Published: February 2023

Este artículo analiza la figura de Josep Maria Tallada i Paulí, economista catalán de la primera mitad del siglo XX. La opción de reconstruir la trayectoria de Tallada tiene que ver con dos razones. En primer lugar, porque fue un intelectual prestado a la política, o un actor político-intelectual: rastrear su trayectoria atendiendo a su contextualización, proporciona la posibilidad de profundizar en la acción de un sector que fue clave en la consolidación de la hegemonía de la Lliga Regionalista antes de la Dictadura primorriverista, siendo Tallada un actor destacado en la construcción de las redes intelectuales y de competencias que sostuvieron ese proyecto. En segundo lugar, su larga trayectoria, firmemente enraizada en los planteamientos racionalistas y modernizantes, permite profundizar en los procesos y las evoluciones que le llevaron -como a otros intelectuales regionalistas-, a adherirse a la Dictadura de Franco después de la Guerra Civil

QUANDO VIVER A UNIVERSIDADE É TAMBÉM REINVENTÁ-LA
Authors: Santos Júlio César de Oliveira
Published: February 2023

Nos últimos anos, as universidades públicas brasileiras vivenciaram intensos processos transformativos, passando de um contexto de democratização do acesso e permanência, a um processo de crise, ou de desdemocratização. No curso desses processos, e com o ingresso de uma série de sujeitos políticos, entre os quais as pessoas LGBTI+, o cotidiano das universidades vem sendo profundamente disputado e transformado. Nesse artigo, argumenta-se, através da análise de narrativas de estudantes LGBTI+ da Universidade Federal de Pernambuco, que gênero e sexualidade constituem a espacialidade da universidade. Não são o que se dá em uma universidade já pronta, que somente abrigaria essas e outras relações. Mas, como o que compõem as disputas pela sua significação, que é parte da própria materialização da universidade, abrindo-a a sentidos de liberdade e normatividade, e constituindo relações, sujeitos e espaços.
QUE AS CORES (NÃO) DIZEM SOBRE GÊNERO E SEXUALIDADE?
Authors: Inoue Gabriela Narumi , Baliscei João Paulo
Published: February 2023

Neste artigo, intenta-se problematizar de que maneiras as construções de gênero e a sexualidade interpelam os artefatos culturais destinados às infâncias e à Educação Infantil, sobretudo no tocante às cores. Utiliza-se da metodologia da pesquisa bibliográfica e debruça-se sobre os aspectos conceituais, históricos e políticos do gênero e da sexualidade, formulados pelos Estudos de Gênero. Também se evidenciam os atravessamentos que gênero e sexualidade promovem nos corpos e, ao mesmo tempo, as resistências que os corpos podem manifestar a tais forças. Por conseguinte, relaciona construção de gênero e sexualidade aos universos e artefatos endereçados às infâncias, recorrendo às bibliografias referentes à temática e aos documentos afetos à Educação Infantil. Compreende-se que as construções de gênero e sexualidade são engendradas social, histórico e culturalmente às infâncias, antes mesmo do nascimento do indivíduo; e delimitam as atuações de masculinidade e feminilidade conforme normatizações específicas, principalmente pelas cores azul e rosa.

Published: February 2023

BACKGROUND: Obesity and androgen deficiency (AnD) are characterized by similar disturbances in metabolic parameters, the presence of signs of insulin resistance, metabolic syndrome, the risk of developing cardiovascular diseases (CVD) and vascular complications. These facts indicate the possibility of the presence of common mechanisms that determine the predisposition to the development of obesity and AnD, which may include genetic factors, in particular, the rs4646994 polymorphism of the ACE gene, which, according to recent data, is associated with the risk of developing CVD, hypertension, and obesity.

AIM: To study the association of the carriage of polymorphic variants of the rs4646994 locus of the ACE gene with the features of anthropometric and androgenic status in men.

MATERIALS AND METHODS: In the period from April 2020 to October 2021 there were observed male patients aged 18–75 years old, who were hospitalized in a therapeutic hospital because of comorbid somatic pathology (hypertension, coronary heart disease, dorsopathy, vegetative-vascular dystonia, gastroesophageal reflux disease, and others). Anthropometry, a study of the content of hormones of the reproductive system in the blood serum using enzyme-linked immunosorbent assay (ELISA), as well as a genetic study for the carriage of polymorphic variants of the rs4646994 locus of the ACE gene by the polymerase chain reaction (PCR) method, followed by electrophoresis of PCR products, were carried out. 

RESULTS: 82 patients took part in research. According to the results of genetic analysis, 17 people were assigned to the group of homozygotes for the wild type (I/I, G1), 41 people were assigned to the group of heterozygotes (I/D, G2), and 41 people were assigned to the group of homozygotes for the mutant allele (D/D, G3) 24 people. Body weight, chest circumference, waist and hips, body mass index in patients carrying the D allele of the rs4646994 polymorphism were statistically significantly higher than in I/I homozygotes. Differences in hormonal status also turned out to be statistically significant: patients from G1 compared with G2 and G3 had higher levels of total testosterone; from G1 compared to G3 — a higher level of free testosterone.

CONCLUSION: An association of the carriage of the D allele of the rs4646994 polymorphic locus of the ACE gene with overweight and ADI was revealed.

Authors: TingChen Chang , Therdthai Nantawan , Soontrunnarudrungsri Aussama
Published: February 2023

Saltiness perception is affected by both extrinsic factors, such as like packaging, receptacle or external environment, and intrinsic factors including sweetness, sourness, and viscosity. This research aimed to study the saltiness perception and sensory profiles of different types of soups. Regarding the effect of xanthan gum, additions of different concentrations of xanthan gum responded to different viscosities in soup samples significantly. Chicken clear soup and Tomyum clear soup without xanthan gum had the significantly lowest viscosity, while Tomyum cream soup and Phanaeng curry with 0.25% xanthan gum had the significantly highest viscosity. Free Choice Profiling showed the first and second dimensions accounted for more than 80% of all soups samples. For the chicken clear soup, both time and xanthan gum only affected the viscosity. According to the consumer test, it was found that xanthan gum had a significant effect on the thickness intensity of all soups, while there was no found significant effect on saltiness perception and acceptance in all types of soup in this study.

Published: February 2023

Objectives

We aimed to determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy is associated with an increased risk of hypertensive disorders of pregnancy (HDP).

Methods

A multicenter retrospective cohort study of all pregnant patients who had SARS-CoV-2 testing and delivered in a large health system between March 2020 and March 2021. Cases were stratified into two groups: patients who tested positive for SARS-CoV-2 during pregnancy vs. patients who tested negative. The primary outcome of HDP, defined as a composite of gestational hypertension, preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP Syndrome), and eclampsia by standard criteria, was compared between the two groups. Statistical analysis included multivariable logistic regression to adjust for potential confounders such as maternal demographics and comorbidities. Patient ZIP codes were linked to neighborhood-level data from the US Census Bureau’s American Community Survey.

Results

Of the 22,438 patients included, 1,653 (7.4%) tested positive for SARS-CoV-2 infection. Baseline demographics such as age, body mass index, race, ethnicity, insurance type, neighborhood-built environmental and socioeconomic status, nulliparity, and pregestational diabetes differed significantly between the two groups. SARS-CoV- 2 infection in pregnancy was not associated with an increased risk of HDP compared to those without infection (14.9 vs. 14.8%; aOR 1.06 95% CI 0.90–1.24).

Conclusions

In this large cohort that included a universally-tested population with several socioeconomic indicators, SARS-CoV-2 infection in pregnancy was not associated with an increased risk of HDP.

Published: February 2023

The objective of this research is to study the limit of linear viscoelastic behavior on a common straight-run bituminous binder at different temperatures and frequencies by performing strain amplitude sweep tests. A dynamic shear rheometer was used for the experimental campaign. An increase of complex modulus due to physical hardening was observed during strain amplitude sweep tests at low temperatures and frequencies. A correction method is proposed to consider the effect of physical hardening on complex modulus when evaluating the linear viscoelastic limit.
Identifying Splitting Through Sentiment Analysis

Published: February 2023

In Kernerg's Object Relations Theory model of personality pathology, splitting, the mutual polarization of aspects of experience, is thought to result in a failure of identity integration. The authors sought to identify a clinician-independent, automated measure of splitting by examining 54 subjects’ natural speech. Splitting in these individuals, recruited from the community, was investigated and evaluated with a shortened version of the Structured Interview of Personality Organization (STIPO-R). A type of automated sentiment textual analysis called VADER was applied to transcripts from the section of the STIPO-R that probes identity integration. Higher variability in speech valence, more negative minimum valence, and more frequent shifts in valence polarity were associated with more severe identity disturbance. The authors concluded that the degree of splitting elicited during the description of self and others is related to the degree of identity disturbance, and to the degree of negativity and instability of these descriptions of self and others.
Securitization in the Shadow of Armed Conflict
Authors: Jaroszewicz Marta , Grzymski Jan
Published: February 2023

This article addresses the discourses and practices of securitization toward internally displaced persons (IDPs) after the Russian military intervention in the eastern part of Ukraine in 2014. It investigates in what ways the IDPs’ rights to vote in the local, parliamentary, and presidential elections in 2015–20 were presented as a security issue. The article discusses this unique case of securitization in the shadow of an armed conflict and the role of othering practices. The data were collected using 15 semi-structured in-depth interviews with IDP activists and experts, selected media, and legal documents. The analysis was conducted by applying a Foucauldian type of discourse analysis. It identified four types of othering practices: “suspicious” citizens and the governmentality of “unease,” routine security practices, the distinctiveness of the Donbas region within Ukraine, and “pragmatic” othering. These four types of othering practices resulted in the institutionalization of the securitization of IDPs and its tacit acceptance by the Ukrainian general public. Nevertheless, it also paradoxically paved the way for the desecuritization of IDPs’ rights, which happened with adoption of a new election code in 2020.
Finding My Front Porch
Authors: Whitworth Colin
Published: February 2023

This essay uses narratives from the author’s life (childhood, adolescence, and young adulthood) to claim that regional identity is an overlooked aspect of intersectionality. By focusing on the intersections of queerness and the U.S. South, this essay approaches region as an example of Yep’s “thickening” intersectionality, using poetry and narrative to make the case that regional identity is a complicating, messy, and inseparable aspect of intersectional identity including preconceived cultural associations and systemic attitudes. By locating narratives along the lines of everyday performance of self, focusing on text and voice, this essay illustrates the inextricable intersectional relationship of place, space, and identity.
The Wake’s Challenge to the Exposición de Puerto Rico
Authors: Barragán Maite
Published: February 2023

This essay analyzes how the presence of Francisco Oller’s monumental painting, The Wake, challenged the narrative of progress set forth in the Exposición de Puerto Rico de 1893 (Fair of Puerto Rico). The fair celebrated four hundred years of Spanish rule over Puerto Rico and emphasized the cultural and economic advancements achieved throughout that time. As a contrast to the many displays of the island’s bounty, The Wake offered a vision of jíbaros (Puerto Rican peasants) celebrating a baquiné, an Afro-Caribbean tradition honoring a deceased child. The painting brought attention to the poverty and marginalization of the peasantry as well as their persistent practice of nonnormative rituals. Oller, like many of the other social-reform-minded intellectuals of Puerto Rico, focused on the jíbaro class in order to critique their lifestyles but also to propel social transformation that could improve peasants’ quality of life. My study intervenes in the scholarly literature of Oller and the politics of the fair to show how The Wake visually asserted the prejudices and deterministic preconceptions about these peasants that characterized the views of late-nineteenth century sociologists. More importantly, however, careful observation of the painting reveals subtle inaccuracies such as the scarcity of food and drink in the scene, errors that conflict with the conclusions intellectuals of the time were drawing about the peasantry. These ambiguous compositional choices disclose an unbridgeable gap between the critique The Wake offered and the fair’s objectives, but they are also central to the painting’s relevance in Puerto Rican culture today.

The genetic changes sustaining the development of cancers of unknown primary (CUP) remain elusive. The whole‐exome genomic profiling of 14 rigorously selected CUP samples did not reveal specific recurring mutation in known driver genes. However, by comparing the mutational landscape of CUPs with that of most other human tumor types, it emerged a consistent enrichment of changes in genes belonging to the axon guidance KEGG pathway. In particular, G842C mutation of PlexinB2 (PlxnB2) was predicted to be activating. Indeed, knocking down the mutated, but not the wild‐type, PlxnB2 in CUP stem cells resulted in the impairment of self‐renewal and proliferation in culture, as well as tumorigenic capacity in mice. Conversely, the genetic transfer of G842C‐PlxnB2 was sufficient to promote CUP stem cell proliferation and tumorigenesis in mice. Notably, G842C‐PlxnB2 expression in CUP cells was associated with basal EGFR phosphorylation, and EGFR blockade impaired the viability of CUP cells reliant on the mutated receptor. Moreover, the mutated PlxnB2 elicited CUP cell invasiveness, blocked by EGFR inhibitor treatment. In sum, we found that a novel activating mutation of the axon guidance gene PLXNB2 sustains proliferative autonomy and confers invasive properties to stem cells isolated from cancers of unknown primary, in EGFR‐dependent manner.

Empirical analysis on the links between geography and energy access in archipelago setting is still limited. In particular, the territorial identification of energy poverty in Indonesia is still missing. Our study maps geographical location and estimates factors that determines the probability of being energy poor household in relation to electricity. We used the OLS (Ordinary Least Square) estimation and utilized the socioeconomic survey (Susenas) combined with data on terrain elevation, presence of geographic features such as mountainside, topography characteristics, ocean and forest obtained from the village census (PODES). The results show that energy poverty in Eastern part of Indonesia is larger than in the Western. In Eastern Indonesia, we estimate that 13.5% of the total households are energy poor compared to the Western which only 7.21%. Households located in the forest area was the dominant factor to influence prevalence of energy poverty among geographic constraints, with magnitude of influence at 22-23 percentage point to non-forest residents. Secondly, the presence of steep-sloped terrain is the next meaningful geographical constraint with contribution effect to energy poverty prevalence at around 18 percentage point. The result highlighted priority of locations in which resource and policy to reduce energy deprivation need to be allocated.
EDUCATED UNEMPLOYMENT AND PERSONAL CHARACTER
Authors: Susanto Joko , Siswanto Yuni
Published: February 2023

This study identifies the factors causing unemployment of vocational high school graduates due to the mismatch between the mismatch demand and supply of labor. The research uses primary data obtained from questionnaires to several vocational high school graduates accompanied by interviews with several entrepreneurs and labor experts in Yogyakarta Special Region. This study utilizes qualitative analysis obtained through focus group discussions (FGD) and the Delphi method to identify the cause of educated unemployment. The results indicate that the dominant factor in worker’s success is the personal character. The vocational high school graduates have advantages in hard skills and soft skills but they are weak in personal character. If they have not found jobs as they expected, they tend to wait for jobs vacancies. During the waiting process, they are included in the unemployed group. Their choices lead to educated unemployment. Therefore, all the stakeholders should strengthen the youth's character.
The Dynamics of Macroeconomic and Microeconomic Determinants with The Capital of Rural Banks
Authors: Ponziani Regi Muzio
Published: February 2023

The research aims to investigate the dynamics among rural banks’ capital, macroeconomic variables and microconomic variables. Macroeoconomic variable consists of infllation and interest. Microeconomic variables consist of loan to deposi ratio, nonperforming loans, and return on assets. The data are excerpted from OJK and BI’s website. The data are monthly data extending from January 2010 until May 2021. The testing method used is vector error correction model (VECM). The results show that rural banks’ capital is significantly affected the previous state of capital and profitability. This indicates the importance of sustainability of capital in rural banks and how it is very much dependent upon the profitability of the rural banks. Further, the research results show that there ar two cointegrating functions in the model. Both cointegration functions are influential to inflation. The speed adjustment derived from the residuals of capital function is 0.6754% and 13.5669% for residual from inflation function itself. The slow adjustment process is due to the small market share and assets of rural banking sector. In addition, capital, nonperforming loans, and return on assets are pivotal for central bank monetary policy to control inflation.
Industrialization and Convergence of West Java Manufacturing Labor Productivity, Indonesia

West Java as a national manufacturing center has experienced industrialization since 1989. This is marked by the continuous increase in the manufacturing sector so that it is able to shift other sectors. Unfortunately, the industrialization that occurred in West Java was not followed by a reduction in the manufacturing labor productivity in West Java. The convergence of manufacturing labor productivity in West Java is an important phenomenon because inequality can lead to a different pace of development and exacerbate inequality. This study uses dynamic panel data regression with the first-different GMM (FD-GMM) method for inferential analysis and Location Quotient (LQ), Klassen Typology and the calculation of the coefficient of variation for descriptive analysis. The results showed that only 7 out of 27 regencies/cities in West Java had the economy dominated by the manufacturing sector and there were fluctuations in the productivity of the manufacturing workforce in these areas. Based on Klassen's Typology, there are still many areas that are categorized as developing and underdeveloped areas. However, there is a decrease in inequality between regions as seen from the results of the convergence analysis. Sigma convergence and beta convergence occurred in West Java with the time needed to close half the gap (half-life convergence) of less than one year. Factors that significantly affect the convergence process of manufacturing labor productivity are the manufacturing labor productivity lag, FDI, DDI, and real wages of manufacturing workers.

Agriculture takes an important role for economy by more than 14% of economic contribution. Nevertheless, it has indirective effects, where it has commonly a negative impact, but somehow in the long term, offers a better environmental service. This study, therefore, aimed to evaluate both impact by estimating the Indonesia food barn to estimate how far the impact to environment through the Environmental Kuznets Curve (EKC). In order to improve the environmental quality in the long term, the sustainable practices through ecolabelling product have to be conducted. Thus, the evaluation of consumers’ WTP for ecolabelling product has been observed through 300 respondents depicting their preferences. Following by AHP analysis to construct the priority of strategies to develop the sustainable agriculture. Based on the results, EKC model showed it initially leads to environmental damage, but at a certain level, people begin to increase environmental awareness by a decrease of methane (CH4) about 0.12%. It is proved by their WTP where 82.6% respondents were willing to pay for ecolabelling product. Finally, to support sustainable agriculture, reforming the market access is a top priority (0.312 points) which aimed to progressively encourage the farmers’ supply. Otherwise, the pricing strategy becomes the consumers’ main perspective to buy (0.264 points).

In the case of Indonesia, manufacturers from abroad have collaborated with Indonesia by buil di ng t hei r own factories so that this is expected to help economic development in the country , but this doesn’t happen in 2020. In the contrary, since the Pandemic of Covid-19, the automotive industry, one of whi ch i s four -wheeled vehicles or cars, experienced a significant decline in exports. Therefore, the purpose of this research is to find out and analyze how the ratio of exports of four or more wheeled vehicles from Indonesia to the main destination countries, especially in the Southeast Asia region and t o di scover and analyze the effect of the exchange rate, population and gross domestic product on the Indonesian export s of four or more wheeled vehicles to main destination countries, especially in the Southeast Asian region. The methods used in this study are descriptive analysis using export ratio and quantitative analysi s using panel data regression. The results showed that based on the ratio of exports of four or more wheeled vehicles from Indonesia to the four main destination countries in Southeast Asi a, t he l argest was t he Philippines with an average of 0.25, followed by Thailand with an average of 0.11 followed by V iet nam with an average of 0.25. an average of 0.049 and finally Malaysia, which is an average of 0.041. The regression results show that the population and exchange rate variables have a significant positive effect while GDP has no significant effect on Indonesia's exports of four or more wheeled vehicles to the four main destination countries in Southeast Asia.
