A teoria da paz democrática e a prevenção de conflitos armados: Análise a partir da Guerra do Cenepa
Authors: Heil de Borba Alice Helena
Published: July 2018

This research aims to perform a test of the Democratic Peace Theory (DPP), under the analysis of the Cenepa War, confronting the main premise of the DPP, which suggests that liberal democratic states do not fight each other. Therefore, the origins of the idea of democratic peace and the main criticisms of it are reviewed. In addition, the War of Cenepa and its antecedents will be presented, so that it can be identified that these events are not adequately explained by the DDP and, therefore, indicate its falsifiability.
Knowledge and authentic development: the value of Political Theory to Development Studies
Authors: Ibeanu Okechukwu , Nwosu Bernard
Published: July 2018

Development studies is a beneficiary of knowledge resources from several disciplines including political theory’s analytic and prescriptive input. The dominant background of political theory and other disciplinary contributions to development studies is the liberal thought. Liberal theses on development seem to presume that development only makes meaning from such perspective. However, tensions arise in knowledge claims between the neoclassical liberals and alternative liberal scholars especially the neo-Keynesian on the one hand and more radical neo-Marxist thoughts on the other hand. The tension is centrally concerned with contention between the market sovereignty of the neoclassicals and state interventionism of the Keynesian and neo Marxist radical thoughts. These contentions draw in the role of the state in development and  hence, create an opening for political theory’s intervention. This paper establishes the nexus of political theory and development studies by focusing its subject matter, methodology and social commitments. The main claim of the work is that the dominant liberal ideas on development fail to capture the realities of all societies, yet the alternative frameworks, despite their promise, have yet to elaborate their tenets to capture the nuances of developing societies in Africa. Accordingly, the decisive intervention in defining the roles of both citizens and state for a development based on constructivist understanding of society is a necessary role of political theory in development studies.
A União Europeia e a (in)segurança no Mediterrâneo e Balcãs: estratégias, vulnerabilidades e desafios
Authors: Xavier Ana Isabel
Published: July 2018

Desde Março de 2015, a União Europeia (UE) tem sido confrontada com uma pressão migratória sem precedentes a partir das rotas do Mediterrâneo e dos Balcãs, naquela que é já considerada a maior crise humanitária desde o final da segunda guerra mundial. Uma análise detalhada da questão conduz-nos a duas evidências empíricas. A primeira, relativamente à resposta da UE enquanto tal que se caracteriza simultaneamente por uma incapacidade de gestão das expectativas e consensos entre os Estados Membros e por uma aparente securitização da política de imigração e asilo com o progressivo reforço da dimensão externa da segurança interna da União. A segunda, relativamente à politização dos movimentos migratórios e a expansão do islamismo por alguns partidos e movimentos com pendor populista extremista um pouco por toda a Europa, tal como ilustrado nas mais recentes eleições na Holanda ou França ou na Alemanha a breve trecho.Assim, este artigo pretende dar um contributo a este debate, traçando o percurso,  impacto e eficácia da abordagem da UE como ator de segurança, bem assim explorando as vulnerabilidades e desafios atuais que se oferecem à UE e aos Estados-membros neste domínio.

AbstractThe results of studying the surface Si layer and precipitate formation in CZ n -Si(100) samples sequentially implanted with ^64Zn^+ ions with a dose of 5 × 10^16 cm^2 and energy of 100 keV and ^16O^+ ions with the same dose but an energy of 33 keV at room temperature so that their projection paths R _ p = 70 nm would coincide are presented. The post-implantation samples are annealed for 1 h in an inert Ar medium in the temperature range of 400–900°C with a step of 100°C. The profiles of the implanted impurities are studied by time-of-flight secondary ion mass spectrometry. The Si surface is visualized using a scanning electron microscope, while the near-surface layer is visualized with the help of maps of elements formed by Auger electron spectroscopy with profiling over depth. The ZnO(002) texture is formed in an amorphized Si layer after the implantation of Zn and O ions. ZnO(102) crystallites of 5 nm in size are found in a recrystallized single-crystalline Si layer after annealing in Ar at 700°C.

AbstractThe results of investigations of electrical, optical, and photoelectric properties of CdIn_2Te^4 crystals, which were grown by the Bridgman method are presented. It is shown that electrical conductivity is determined mainly by electrons with the effective mass m _ n = 0.44 m _0 and the mobility 120–140 cm^2/(V s), which weakly depends on temperature. CdIn_2Te_4 behaves as a partially compensated semiconductor with the donor-center ionization energy E _ d = 0.38 eV and the compensation level K = N _ a / N _ d = 0.36. The absorption-coefficient spectra at the energy hν < E _ g = 1.27 eV are subject to the Urbach rule with a typical energy of 18–25 meV. The photoconductivity depends on the sample thickness. The diffusion length, the charge-carrier lifetime, and the surface-recombination rate are determined from the photoconductivity spectra.

AbstractPorphyrins and their fullerene complexes are promising materials for organic photovoltaic structures. However, the stability of the properties of organic components under hard radiation is poorly studied. Here, the influence of γ irradiation with medium (about 10^4 Gy) and large (10^7 Gy) doses on the photoluminescence of thin structurally perfect films of both pure porphyrin ZnTPP and ZnTPP/C_60 composite films in the molar ratio of 1.3: 1 is investigated. It is shown that the intensity of the electronic radiative transition (626 nm) decreases under the effect of γ irradiation, and the dose dependence is threshold. The threshold dose is ~20 kGy for the ZnTPP films. The intensity of the electron-vibrational part of the spectral dependence of the PL (670–690 nm) for both types of samples decreased at initial irradiation doses and decreases less with a further increase in the irradiation dose than for the purely electron transition. The addition of a fullerene in nanocomposite films increases the threshold dose, after which the PL of the films started to degrade, by a factor of ~2.5. Herewith, the spectral components of the PL associated with the manifestation of the radiation transition of the fullerene C_60 are more stable under γ irradiation.

AbstractThe (MnIn_2S_4)_1– x • (AgIn_5S_8)_ x alloy single crystals are grown for the first time by the Bridgman method in the entire range of component concentrations. The composition of the single crystals and their crystal structure are determined. It is shown that the alloy crystallizes in the cubic spinel structure. The unit-cell parameter of the single crystals ( a ) is calculated, and its dependence on the composition parameter ( x ) is determined.

AbstractThe magnetization properties of a ferromagnet-semiconductor Co/CdMgTe/CdTe quantum well hybrid structure are investigated by several techniques. Exploiting the proximity effect between acceptor bound holes and magnetic ions we detect the magnetization curves by measuring the circular polarization of photoluminescence in an out-of-plane magnetic field. We show that magnetization originates from interfacial ferromagnet on Co-CdMgTe interface and the proximity effect is caused by magnetization of interfacial Co-CdMgTe ferromagnetic layer whose magnetic properties are very different from Co.

AbstractThe evolution of the spatial coherence and the polarization has been studied in a freely decaying polariton condensate that is resonantly excited by linearly polarized picosecond laser pulses at the lower and upper sublevels of the lower polariton branch in a high-Q GaAs-based microcavity with a reduced lateral symmetry without excitation of the exciton reservoir. It is found that the condensate inherits the coherence of the exciting laser pulse at both sublevels in a wide range of excitation densities and retains it for several dozen picoseconds. The linear polarization of the photoexcited condensate is retained only in the condensate at the lower sublevel. The linearly polarized condensate excited at the upper sublevel loses its stability at the excitation densities higher a threshold value: it enters a regime of internal Josephson oscillations with strongly oscillating circular and diagonal linear degrees of polarization. The polariton–polariton interaction leads to the nonlinear Josephson effects at high condensate densities. All the effects are well described in terms of the spinor Gross–Pitaevskii equations. The cause of the polarization instability of the condensate is shown to be the spin anisotropy of the polariton–polariton interaction.

AbstractWe describe the major requirements to experimentally perform and observe resonant spin-flip Raman scattering on excitonic resonances in low-dimensional semiconductors. We characterize in detail the properties of this resonant light scattering technique and evaluate the criteria, which must be fulfilled by the experimental setup and the semiconductor sample studied to be able to observe a spin-flip scattering process. We also demonstrate the influence of additional unpolarized laser illumination with energies, which exceed considerably the band gap energy of the semiconductor nanostructure under study, on the resonantly excited electron spin-flip scattering in InAs-based quantum dot ensembles as well as on the paramagnetic Mn-ion spin-flip in (Zn,Mn)Se/(Zn,Be)Se quantum wells.
Critical dependence of the excitonic absorption in cuprous oxide on experimental parameters

Published: July 2018

AbstractWe study the modification of the exciton absorption in cuprous oxide by the presence of free carriers excited through above band gap excitation. Without this pumping, the absorption spectrum below the band gap consists of the yellow exciton series with principal quantum numbers up to more than n = 20, depending on the temperature, changing over to an about constant, only slowly varying absorption above the gap. Careful injection of free carriers, starting from densities well below 1 μm^–3, leads to a reduction of the band gap through correlation effects. The excitons in the Rydberg regime above n = 10 remain unaffected until the band gap approaches them. Then they lose oscillator strength and ultimately vanish upon crossing with the band gap.

Published: July 2018

AbstractLately, the yellow series of P -excitons in cuprous oxide could be resolved up to the principal quantum number n = 25. Adding a magnetic field, leads to additional confinement normal to the field. Thereby, the transition associated with the exciton n is transformed into the transition between the electron and hole Landau levels with quantum number n , once the associated magnetic length becomes smaller than the related exciton Bohr radius. The magnetic field of this transition scales roughly as n ^–3. As a consequence of the extended exciton series, we are able to observe Landau level transitions with unprecedented high quantum numbers of more than 75.

AbstractAn overview on photon echo spectroscopy under resonant excitation of the exciton complexes in semiconductor nanostructures is presented. The use of four-wave-mixing technique with the pulsed excitation and heterodyne detection allowed us to measure the coherent response of the system with the picosecond time resolution. It is shown that, for resonant selective pulsed excitation of the localized exciton complexes, the coherent signal is represented by the photon echoes due to the inhomogeneous broadening of the optical transitions. In case of resonant excitation of the trions or donor-bound excitons, the Zeeman splitting of the resident electron ground state levels under the applied transverse magnetic field results in quantum beats of photon echo amplitude at the Larmor precession frequency. Application of magnetic field makes it possible to transfer coherently the optical excitation into the spin ensemble of the resident electrons and to observe a long-lived photon echo signal. The described technique can be used as a high-resolution spectroscopy of the energy splittings in the ground state of the system. Next, we consider the Rabi oscillations and their damping under excitation with intensive optical pulses for the excitons complexes with a different degree of localization. It is shown that damping of the echo signal with increase of the excitation pulse intensity is strongly manifested for excitons, while on trions and donor-bound excitons this effect is substantially weaker.

AbstractNonlinear optical phenomena are widely used for the study of semiconductor materials. The paper presents an overview of experimental and theoretical studies of excitons by the method of optical second and third harmonics generation in various bulk semiconductors (GaAs, CdTe, ZnSe, ZnO, Cu_2O, (Cd,Mn)Te, EuTe, EuSe), and low-dimensional heterostructures ZnSe/BeTe. Particular attention is paid to the role of external electric and magnetic fields that modify the exciton states and induce new mechanisms of optical harmonics generation. Microscopic mechanisms of harmonics generation based on the Stark effect, the spin and orbital Zeeman effects, and on the magneto-Stark effect specific for excitons moving in an external magnetic field are considered. This approach makes it possible to study the properties of excitons and to obtain new information on their energy and spin structure that is not available when the excitons are investigated by linear optical spectroscopy. As a result of these studies, a large amount of information was obtained, which allows us to conclude on the establishing of a new field of research—exciton spectroscopy by the method of optical harmonics generation.

AbstractWe present a review of spin-dependent properties of excitons in semiconductor colloidal nanocrystals. The photoluminescences (PL) properties of neutral and charged excitons (trions) are compared. The mechanisms and the polarization of radiative recombination of a “dark” (spin-forbidden) exciton that determines the low-temperature PL of colloidal nanocrystals are discussed in detail. The radiative recombination of a dark exciton becomes possible as a result of simultaneous flips of the surface spin and electron spin in a dark exciton that leads to admixture of bright exciton states. This recombination mechanism is effective in the case of a disordered state of the spin system and is suppressed if the polaron ferromagnetic state forms. The conditions and various mechanisms of formation of the spin polaron state and possibilities of its experimental detection are discussed. The experimental and theoretical studies of magnetic field-induced circular polarization of PL in ensembles of colloidal nanocrystals are reviewed.

AbstractZrO_2(Y) ceramic with embedded particles of a pore-forming agent—ultrahigh molecular weight polyethylene—has been studied. It has been shown that the porosity of samples after sintering changed from 2 to 42 vol % and the grain size changed from 0.5 to 1.55 μm depending on sintering regime. The strength of materials with minimum porosity was 3000 ± 200 MPa, while the strength of materials with maximum porosity was 100 ± 20 MPa, regardless of grain size. It has been shown that the tetragonal to monoclinic martensitic phase transformation related to mechanical stresses takes place in the material without any effect on the macrostrength of the material. Internal microscopic stresses decreasing with an increase in porosity and ceramic grain size are the main factor causing this transformation in a porous material.

AbstractIt is proposed to characterize levels of deformation by a size of its jumps, which can be observed when the strain rate is accurately measured in experiments with load that is constant or defined according a certain law. At the micro- and nanometer scales, the strain rate was measured and the deformation jumps were computed for copper, lead, and tin using a precision interferometric method. A correlation of the size of jumps with the Burgers vector of dislocations in metals was shown, and hypotheses about ensembles of dislocations participating in the formation of a deformation jump are made.

AbstractThermodynamic spin fluctuations in strongly correlated plutonium (Pu) phases with exchange and spin–orbit interactions are considered. In α- and δ-Pu phases, the spin fluctuations lead to a negative magnetovolume effect that is determined by the parameter of intermode coupling and depends on features of the electron structure. It is shown that the negative volumetric thermal expansion coefficient of δ-Pu is related to an anomalously strong interaction of spin fluctuation modes.

Published: July 2018

BACKGROUND

For older adults, physical activity is vital for maintaining their health and ability to live independently. Home-based programs can help them achieve the recommended exercise frequency. An application for a tablet computer was developed to support older adults in following a personal training program. It featured goal setting, tailoring, progress tracking, and remote feedback.

OBJECTIVE

In line with the Medical Research Council Framework, which prescribes thorough testing before evaluating the efficacy with a randomized controlled trial, the aim of this study was to assess the usability of a tablet-based app that was designed to support older adults in doing exercises at home.

METHODS

A total of 15 older adults, age ranging from 69 to 99 years old, participated in a usability study that utilized a mixed-methods approach. In a laboratory setting, novice users were asked to complete a series of tasks while verbalizing their ongoing thoughts. The tasks ranged from looking up information about exercises and executing them to tailoring a weekly exercise schedule. Performance errors and time-on-task were calculated as proxies of effective and efficient usage. Overall satisfaction was assessed with a posttest interview. All responses were analyzed independently by 2 researchers.

RESULTS

The participants spent 13-85 seconds time-on-task. Moreover, 79% (11/14)-100% (14/14) participants completed the basic tasks with either no help or after having received 1 hint. For expert tasks, they needed a few more hints. During the posttest interview, the participants made 3 times more positive remarks about the app than negative remarks.

CONCLUSIONS

The app that was developed to support older adults in doing exercises at home is usable by the target audience. First-time users were able to perform basic tasks in an effective and efficient manner. In general, they were satisfied with the app. Tasks that were associated with behavior execution and evaluation were performed with ease. Complex tasks such as tailoring a personal training schedule needed more effort. Learning effects, usefulness, and long-term satisfaction will be investigated through longitudinal follow-up studies.

Hybrid Vigor

Published: July 2018

The ecological approach to rationality involves evaluating choice processes instead of choices themselves, and there are good reasons for doing this. Proponents of the ecological approach insist that objective performance criteria (such as monetary gains) replace axiomatic criteria, but this claim is highly contentious. This paper investigates these issues through a case study: 12 risky choice processes are simulated, and their performance records are compared. The first criterion is conformity to the Expected Utility axioms; the Priority Heuristic stands out for frequently violating Transitivity. Next, the Expected Value criterion is applied. Minimax performs especially poorly—despite never violating an axiom—highlighting the tension between axiomatic (coherence) and objective (correspondence) criteria. Finally, I show that axiom violations carry high costs in terms of expected value. Accordingly, coherence does not guarantee objectively high performance, but incoherence does guarantee diminished performance.

Published: July 2018

Perempuan dalam masyarakat yang patriarkat berada dalam posisi yang kurang menguntung bahkan cenderung berada dalam posisi tidak berdaya. Ketidakberdayaan ini dapat dilihat dari tidak adanya kesempatan dalam mengambil keputusan dalam hidupnya termasuk pengambilan keputusan yang berkaitan dengan dirinya. Ketidakberdayaan ini menjadikan perempuan dalam kondisi yang marginal dalam kehidupan bermasyarakat.Ketidakberdayaan perempuan ini juga dapat dilihat dalam program KB. Keputusan untuk menggunakn alat kontrasepsi lebih banyak ditentukan oleh pihak laki-laki. Bahkan untuk mejadi akseptor KB juga ditentukan oleh pihak lain khususnya laki-laki. Sementara itu pihak laki-laki sangat sedikit yang menjadi akseptor KB. Hal ini dikarenakan keputusan untuk menjadi akseptor KB ada ditangan laki-laki, sehingga ada keengganan pihak laki-laki menjadi akseptor KB.Program KB tidak hanya berkaitan dengan menjadi akseptor KB saja tetapi juga banyak program yang bekaitan dengan pemberdayaan khususnya perempuan. Program-program pemberdayaan perempuan dalam program KB berhubungan dengan kegiatan pemberdayaan yang selanjutnya dikaitkan dengan kehidupan KB. Hasilnya dengan program KB masih sedikit yang dapat memberdayaan perempuan. Hal ini dikarenakan masih kuatnya dominasi laki=laki dalam kehidupan sehari-hari.

Kegiatan penguatan kelembagaan koperasi bagi petani kopi dan tembakau di Desa Genteng Kecamatan Sukasari Kabupaten Sumedang ini dilatarbelakangi oleh keberadaan koperasi di Desa Genteng yang belum sepenuhnya berfungsi bagi warga masyarakat dan belum dimanfaatkan secara optimal oleh warga sekitar. Hal tersebut disebabkan oleh karena masyarakat yang belum mengetahui manfaat dari koperasi itu sendiri. Masyarakat juga hanya mengetahui satu fungsi koperasi yaitu untuk memberikan bantuan modal dalam bentuk uang. Padahal terdapat beberapa fungsi lainnya dari koperasi, diantaranya yaitu untuk mengembangkan potensi warga masyarakat dan daerah sekitar, serta dapat menjadi wahana untuk meningkatkan kemampuan ekonomi anggota koperasi dan juga masyarakat secara umum. Berdasarkan situasi tersebut, maka diperlukan berbagai upaya untuk meningkatkan pengetahuan pada masyarakat tentang keberadaan dan fungsi koperasi di Desa Genteng, dengan tujuan agar para petani kopi dan tembakau dapat memanfaatkan keberadaan koperasi tersebut secara optimal.

Retardasi mental merupakan salah satu fenomena masalah pada bidang kesehatan mental yang dapat menimpa penduduk Indonesia. Fenomena penduduk dengan retardasi mental di Desa Sidoharjo Kecamatan Jambon Kabupaten Ponorogo merupakan contoh kasus dari beberapa wilayah lainnya yang ada di Indonesia. Fenomena penduduk dengan retardasi mental di daerah tersebut membuat daerah tersebut dijuluki sebagai “Kampung Gila”. Daya tarik lainnya yang membuat desa ini dikenal oleh masyarakat lainnya ialah hubungan sosial masyarakatnya yang berdampingan satu sama lain antara penduduk normal dan penduduk dengan retrdasi mental. Hubungan sosial yang ada pada masyarakat desa tersebutlah yang menjadi sumber dari adanya modal sosial yang muncul dari internal masyarakat. Ketersediaan modal sosial tersebutlah yang dapat digunakan oleh masyarakat sebagai sumber dalam melakukan pelayanan maupun sebuah sistem pengembangan penanganan penduduk dengan retardasi mental. Guna mendukung ketercapaian modal sosial itu sendiri tentunya terdapat tiga unsur pendukung yaitu kepercayaan, jaringan dan norma.

Kenakalan remaja merupakan hal yang tidak jarang kita temui saat ini. Kenakalan remaja pun tak urung timbul dari sebuah komunitas remaja. Tawuran antar pelajar dari komunitas-komunitas di sekolah, ugal-ugalan di jalan raya, berpesta minuman keras adalah sebagian contoh dari tindakan kenakalan remaja dalam komunitas. Kenakalan remaja tersebut dapat terjadi dari pengaruh suatu komunitas. Remaja di Kota Bandung sudah sangat akrab dengan budaya yang mengharuskan seorang remaja masuk ke dalam komunitas. Akibatnya, Kota Bandung terkenal dengan komunitas antar sekolah untuk para remaja, komunitas geng motor dan komunitas lainnya. Sayangnya banyak pandangan negatif karena biasanya komunitas remaja sering melakukan tindak kenakalan dan tak jarang meresahkan lingkungan serta masyarakat sekitar. Padahal sudah cukup diakui secara global adanya tindak kenakalan remaja disebabkan faktor-faktor tertentu. Jika sudah banyak penelitian yang mencari faktor penyebab adanya tindak kenakalan remaja, penelitian ini lebih memfokuskan kepada faktor-faktor penyabab masuknya remaja dalam komunitas yang sering melakukan tindak kenakalan remaja. Dengan cara observasi langsung dan wawancara mendalam dengan anggota komunitas yang terkenal sering melakukan tindak kenakalan, diharakpakn penelitian ini dapat menyimpulkan fakor penyebab yang mendukung remaja bergabung. Faktor penyebab remaja bergabung dalam sebuah komunitas kenakalan remaja, diyakini mempunyai dua faktor penentu yaitu faktor pendorong dan faktor penarik.

Program Pengabdian Pada Masyarakat (PPM) ini dilatarbelakangi oleh pola pikir masyarakat yang masih menganggap bahwa sampah adalah sumber masalah, sehingga masyarakat umumnya menilai bahwa sampah adalah benda yang sudah tidak ada manfaatnya. Masyarakat belum terarah pada pemikiran bahwa sampah bila dikelola dan diolah dapat menjadi potensi yang menguntungkan bagi masyarakat itu sendiri. Kegiatan PPM di adakan di Desa Genteng, Kec. Sukasari, Kab. Sumedang yang memang masih memiliki masalah yang terkait dengan sampah tersebut. Desa Genteng merupakan salah satu desa yang memiliki potensi sumber daya alam yang melimpah, namun pengelolaan sumber daya alam tersebut seringkali menimbulkan dampak terhadap peningkatan jumlah sampah organic dan non-organik yang belum ditangani dengan tepat.Dalam mengatasi masalah tersebut, tim bermaksud mengadakan kegiatan berupa pelatihan mengenai pengolahan sampah organik dan non organik yang dihasilkan dari pengelolaan sumber daya alam maupun sampah rumah tangga. Tujuan dari kegiatan ini adalah agar masyarakat sadar bahwa sampah bukan lagi sebuah masalah, namun justru sampah adalah potensi yang menguntungkan bilamana masyarakat memahami dan memiliki keterampilan dalam mengolah sampah tersebut. Kegiatan PPM ini akan berlangsung selama 7 bulan, dan dapat ditindaklanjuti dengan berbagai kegiatan yang mendukung hasil pelatihan pengolahan sampah tersebut.Hasil dari kegiatan pelatihan tersebut, nampak bahwa warga lebih termotivasi untuk mulai memilah sampah organik dan non-organik dengan metode pengolahan dan pengelolaan yang bernilai ekonomis sebagai potensi usaha yang ramah lingkungan.
