Job-Finding and Job-Losing: A Comprehensive Model of Heterogeneous Individual Labor-Market Dynamics
Authors: Hall Robert E. ,   Stanford University, Kudlyak Marianna ,   Federal Reserve Bank of San Francisco
Published: March 2019

We study the paths over time that individuals follow in the labor market, as revealed in the monthly Current Population Survey. Some people face much higher flow values from work than in a non-market activity; if they lose a job, they find another soon. Others have close to equal flow values and tend to circle through jobs, search, and non-market activities. And yet others have flow values for non-market activities that are higher than those in the market, and do not work. We develop a model that identifies and quantifies heterogeneity in dynamic individual behavior. Our model provides a bridge between research on monthly transition rates in the tradition of Blanchard and Diamond (1990) and research on economic dynamics in the tradition of Mortensen and Pissarides (1994). Our estimates discern 5 distinct types. Most unemployment comes from just two of those types. Low employment types frequently circle among unemployment, short-term jobs, and being out of the labor market. Short-term jobs play a role in the job-finding process related to the role of unemployment. These are stop-gap jobs for high-employment types and a part of circling for low-employment types. Because of their high job-finding rates, and despite their low flow values of non-work relative to work, the volatility of the future lifetime value that high-employment types derive from work and non-work is lower than for low-employment types.

Análisis psico-social de las concepciones, atribuciones y prejuicios de profesionales comunitarios/as sobre las personas que viven en la calle en Quito, 2016-2017
Authors: Navas Espinosa Rosa Estefanía
Published: March 2019

La realidad de las personas que viven en la calle en Ecuador es preocupante, lo cual indica la pertinencia de abocarse al estudio de este fenómeno. Al respecto, se ha identificado que lo que prima en la producción académica en el país son investigaciones en torno a diversos aspectos de estas poblaciones, siendo escasa la indagación sobre las concepciones y prejuicios de los/as profesionales que trabajan con las personas que viven en las calles. Por ello, se realizó una investigación empírica cualitativa, con alcance descriptivo, con el objetivo de profundizar desde la perspectiva de la Psicología Socio-cognitiva en las perspectivas de los/as profesionales comunitarios/as abocados al trabajo cotidiano con estas poblaciones. Así, se realizaron entrevistas semiestructuradas a 14 profesionales de distintas instituciones inmiscuidas en proyectos de inclusión social orientados a personas que viven en la calle en el Ecuador.
Aspects on the History of Observations and Measurements in the Black Sea Coastal Zone, Rehabilitation Projects and Marine Modeling Issues
Authors: Borcia Constantin
Published: March 2019

Over time, the content, scope and objectives of hydrological research in the Romanian Black Sea coastal area varied according to the state of society development, technology development and financial resources. Along with the activities of capitalizing on natural resources, water use, river and sea navigation, there have been demands for knowledge of the water regime and the interaction between the resource potential and the characteristics of the hydrological regime. As a result, hydrographic and hydrological research was started and developed in the Black Sea coastal zone. These researches developed in the first half of the nineteenth century, and then continued throughout this century and later in the twentieth century, with interruptions caused by the two world wars. Among the important activities that have taken place over time, there have been hydro-technical works. The design and elaboration of the projects of these works were based on the knowledge of the hydrographic and hydrological characteristics of the Black Sea coastal zone. This knowledge has evolved over time so that there is currently an important pool of data and information related to the hydrological, morphological, hydrochemical, hydrobiological characteristics of the water bodies mentioned.

The paper presents briefly the most important moments of the history of the monitoring activity carried out over time in the Black Sea coastal zone, the types of coastal and transitional waters in Romania, coastal rehabilitation projects of the Black Sea, hydrological features, the structure of the marine complex model pom / ersem III) BREG / BSHELF.

In order to provide a full adaptation to the users’ variable demands, variable speed motor driven pumps are used on networks (such motors being equipped with frequency converters). The paper presents a method for determining the global efficiency of a frequency converter-asynchronous motor-pump group. The method has been implemented at the Chiriţa Pumping Station, main facility within the Iasi City water supply system.
The Theoretical Foundation of the Concept of “Architecture and the Built Environment Education”
Authors: Filip Irina Cerasela , Filip Cosmin
Published: March 2019

It is necessary to investigate, develop and promote architecture and built environment education in order to increase the civic responsibility towards the built environment and to create a functional, sustainable and aesthetic environment.

This type of education can and should lay the foundation for social responsibility but for this, we need to make children and young people understand what being responsible mean and that the city is the result of the involvement of all its inhabitants.

Forming such citizens that are able to understand the idea that active involvement and prospective thinking is the first step towards a sustainable transformation of society is a complex and lasting process, which is why it has to start from an early age.
Using content-based and task-based teaching in a critical thinking setting to improve EFL learners’ writing
Authors: Marashi Hamid , Mirghafari Samira
Published: March 2019

The purpose of this study was to compare the effect of content-based and task-based instruction in a critical thinking setting on EFL learners’ writing. Accordingly, 60 female learners out of a total number of 90 intermediate learners studying at a language school in Tehran were selected after taking a piloted sample of the Preliminary English Test (PET) for homogenization prior to the study. Subsequently, they were put into two experimental groups: 30 learners in the content-based teaching group and 30 learners undergoing the task-based teaching treatment. Both experimental groups experienced the two teaching approaches in a critical thinking setting. A sample PET writing was administered as the post-test of the study after 16 sessions of treatment spanning nine weeks. A comparison of the mean scores of the two groups on this post-test through an independent samples t-test revealed that there was no significant difference between the two groups at the post-test. The probable reason for this result together with the pedagogical implications of this study and the suggestions for further research are elaborated extensively in the paper.
Investigating demotivational factors in Indonesian EFL classrooms: The case of madrasa students
Authors: Husniyah Af'idatul
Published: March 2019

Compared to motivation, demotivation is still a relatively new topic in the field of language learning. This present study aims to investigate demotivational factors among Madrasa (religious educational institution) students in the Indonesian EFL context. This study employed a mixed-methods approach with an explanatory design in which the quantitative phase was conducted before the qualitative phase. A 25-close-ended questionnaire along with one open-ended question were filled by 190 Madrasa students. To expand the results of the questionnaire, interviews with two students were conducted. Through a descriptive analysis and thematic analysis, five key demotivators were revealed, they are a) the nature of the target language, b) lesson-specific factors, c) learning materials, d) teacher-related factors, and e) the learning environment. The results also indicated some factors which are not included in the questionnaire, they are a) lack of self-confidence, b) lack of intrinsic motivation, c) lack of learning community, and d) teacher gender. Although previously students’ religious beliefs were said to affect the students’ demotivation, it appeared that half of the students did not consider them to be demotivating. Instead of religious beliefs, the students found the nature of English as the most demotivating factor, which contradicts the findings of previous demotivation studies that found teachers as the main demotivating factor.

Published: March 2019

Melon breeding for fruit quality improvement is important to produce new varieties that meet consumers’ demand. The aim of this study was to elucidate the fruit characteristics of melon at five different maturity stages, involving several genotypes belonging to two cultivar groups: reticulatus and inodorus. The experiments were conducted in three planting seasons: (1) January-March 2015 (13 genotypes), (2) December 2015-February 2016 (56 genotypes), (3) February-May 2016 (9 genotypes). These trials were conducted at the Tajur II experimental station of IPB, Bogor, and each trial was arranged in a single factor randomized complete block design with three blocks. Maturity stages was determined based on fruit rind color and net coverage, and their effects on fruit quality were studied using combined analyses over seasons. Maturity stage significantly affected the fruit length, fruit diameter, flesh thickness, fruit weight, and sugar content. The average weight of the fruits at maturity stage 4 (838.90 g) and 5 (931.79 g) was significantly greater than that of stage 1 (584.42 g). The sugar content increased from maturity stage 2 (5.51 oBrix) to 3 (6.13 oBrix) and to 5 (8.18 oBrix). Fruit weight significantly correlated with fruit length (r = 0.53), fruit diameter (r = 0.85), fruit rind thickness (r = 0.33), and flesh thickness (r = 0.63). Maturity stages affected the quality of melon fruits, and therefore the determination of appropriate harvesting criteria is important in melon cultivations.Keywords: cantalupensis, correlation, inodorus, fruit quality, skin colour

Authors: Krisnawati Ayda , Adie And Mochammad Muchlish
Published: March 2019

Genotype × environment interaction is universal phenomenon when different genotypes are tested in a number of environments. The objective of this experiment was to determine the seed yield stability of soybean genotypes. Seven soybean genotypes and two check cultivars were evaluated at eight soybean production centers during the dry season 2015. Stability analysis on seed yield was based on the GGE biplot method. The combined analysis showed that yield and yield components were significantly affected by genotype (G), environments (E), and genotype × environment interaction (GEI), except for number of filled pods. The highest yield was G6 (3.07 ton ha-1), followed by G7 (2.93 ton ha-1). The “which-won-where” polygon mapping resulted two mega-environments. The best genotype for the first mega-environment was G1 (G511H/Anjasmoro//Anjasmoro-2-8) at E5 (Pasuruan2); and the second one was G6 (G511 H/Anj//Anj///Anj////Anjs-6-7) at E1 (Nganjuk), E2 (Mojokerto), E3 (Blitar), E4 (Pasuruan1), E6 (Jembrana), E7 (Tabanan), and E8 (Central Lombok). The G7 (G511 H/Anjasmoro-1-4-2) was closest to ideal genotype as indicated by relatively stable and produced high yield across environments. The analysis of multi-environment trials data using GGE is useful for determining mega-environment analysis and stability of genotype which focusing on overall performance to identify superior genotypes.Keywords: GE interaction, GGE biplot, Glycine max, seed yield
Varieties Of Social Unionism: Towards a Framework for Comparison
Authors: Ross Stephanie
Published: March 2019

In academic and activist debates about union renewal, the replacement of business unionism with social unionism is seen as central to the labour movement's short- and long-term survival. Social unionism, generally understood to involve both engagement with social justice struggles beyond the workplace and methods of union activity beyond the collective bargaining process, is claimed to increase the labour movement's organizing capacity, bargaining power, and social and political weight. However, despite its increased importance, social unionism's various meanings, strategies, and implications remain relatively unexamined, and very different approaches are often lumped together. Using concepts from social movement theory, this paper proposes an analytical framework for systematically comparing different concrete manifestations of social unionism. In particular, social unionist initiatives vary according to 1) the ethos or collective action frame used to rationalize union activity; 2) the repertoire or strategic means used to act on that ethos; and 3) the internal organizational practices and power relations which shape who is involved in defining and carrying out union goals and initiatives. I argue that whether social unionist projects are able to reach immediate instrumental goals as well as generate renewed working class / movement capacity is shaped by both the mix of frame, repertoire and organizational practice as well as the relationship between these three. The paper therefore asserts that the category "social unionism" must be more nuanced, and calls for a more explicitly comparative and multi-methodological approach to reveal such complexity.
Limitations to Inclusive Unions from the Perspectives of White and Aboriginal Women Forest Workers in the Northern Prairies
Authors: Mills Suzanne E
Published: March 2019

Several authors have argued that broadening the traditional understandings of union solidarity is necessary for union renewal. Concerns specific to workers from marginalized groups have been shown to challenge traditional understandings of union collectivity. This paper draws on interviews with white and Aboriginal women forest processing workers to argue that interrogating marginalized workers' negative representations of their unions can provide insights that will help to broaden traditional understandings of union solidarity. I use thematic analysis followed by critical discourse analysis to examine women workers' negative talk about unions. I present examples of how women's negative representations of their unions can be understood as different forms of collectivism when examined in the context of their lived experiences of work and unionism. Some white and Aboriginal women's representations of their unions wove individualistic anti-union statements together with their previous experiences of work highlighting the inequality between unionized and non-unionized workers in the community. The talk of other Aboriginal women critiqued the union for not representing them while demonstrating a sense of collectivity with other Aboriginal workers. By exploring linkages between women's negative representations of unions and their work experiences, unions can better understand the negative union sentiment of marginalized workers and use this to create more inclusive forms of solidarity.

Rose, locally called Gulab-Jo-Gul (In Sindhi) belongs to family Rosaceae.Â  Its botanicalname is Rosa indica L. in the order Rosales. Rosaceae is a larger plant family which have hundreds (100) of generas and over thousands of species which contains shrubs, herbs and trees etc. Rose is very much important plant from various aspects. It is widely used throughout the world including love movements, medical purposes, cosmetic uses, happy events, celebrations, welcome parties, ornamentallyas well as food tonic supplement, so, they have value but same time they are cultivated at small area in the country due to several reason. However they are climatically well adopted and tolerates adverse environmental conditions. Lack of improved production technology plus awareness about cultivation are major issues in every part of the globe. Unfortunately in agricultural research life, rose cultivation sector is most ignored around the world, less work and less promotion of its cultivation causing reduced availability. Therefore introduction of climatically well adopted production technology is essential which provides briefly guide to formers from scope of rose along with cultivation processes.Â

An adamantane-linked tetracene dyad (Tc–Ad–Tc) undergoes exergonic intramolecular singlet fission (SF), producing longlived (τ = 175 μs) and high-energy (2 x 1.03 eV) multiexcitons. Timeresolved absorption, fluorescence decay, and electron paramagnetic resonance (EPR) spectroscopic analysis revealed that the long-lived triplet species is generated in this system via correlated triplet pair having singlet and quintet characteristics. Time-resolved EPR analysis revealed that conversion of 1(3Tc–Ad–3Tc)* -> 5(3Tc–Ad–3Tc)* requires small conformational dynamics accompanied by molecular motion. Analysis of the geometries of the quintet states shows that formation of the long-lived multiexciton is enabled by precise and close alignment of the tetracene moieties, which leads to their moderate interaction in the singlet excited state, while triplet–triplet annihilation is prevented by quintet generation. The presence of aliphatic linkages, like the rigid adamantane group, might enable effective conservation of intrinsic S1 and T1 levels of the original monomers, and moderate bridge-mediated σ–π interaction leading to exergonic intramolecular SF involving 1Tc*–Ad–Tc -> 1(3Tc–Ad–3Tc)*.
A Chemical Perspective to the Anti-Amyloid Action of Compounds and a Nanoparticle Based Assay for Screening Amyloid Inhibitors

Published: March 2019

Aggregation of amyloid beeta 1-42 (Aβ42) peptide causes the formation of clustered deposits knows as amyloid plaques in the brain which leads to neuronal dysfunction and memory loss and associated with many neurological disorders including Alzheimer’s and Parkinson’s. Aβ42 has core structural motif with phenylalanine at the 19 and 20 positions. The diphenylalanine (FF) residue plays a crucial role in the formation of amyloid fibers and serves as model peptide for studying Aβ42 aggregation. FF self-assembles to well-ordered tubular morphology via aromatic pi-pi stackings. Our studies, suggest that the aromatic rings present in the anti-amyloidogenic compounds may interact with the pi-pi stacking interactions present in the FF. Even the compounds which do not have aromatic rings, like cyclodextrin and cucurbituril show anti-amyloid property due to the binding of aromatic ring inside the guest cavity. Hence, our studies also suggest that compounds which may have a functional moiety capable of interacting with the aromatic stacking interactions might be tested for their anti-amyloidogenic properties. Further, in this manuscript, we have proposed two novel nanoparticle based assays for the rapid screening of amyloid inhibitors. In the first assay, interaction between biotin-tagged FF peptide and the streptavidin labelled gold nanoparticles (s-AuNPs) were used. In another assay, thiol-Au interactions were used to develop an assay for detection of amyloid inhibitors. It is envisaged that the proposed analytical method will provide a simple, facile and cost effective technique for the screening of amyloid inhibitors and may be of immense practical implications to find the therapeutic remedies for the diseases associated with the protein aggregation.
Residual Categories: Silence, Absence and Being an Other
Authors: Star Susan Leigh
Published: March 2019

Residual categories such as »not elsewhere categorized« densely populate modern information systems. This article roughly categories two types of modern information surveillance and notification systems, statistical and event-based. It examines the nature of residual categories arising from each, and proposes some methodological considerations for how these impact moral order within information infrastructure. The article concludes with comments about how the inclusion of lived experience might ameliorate a sort of moral gridlock often encountered today in large-scale information systems.
Alphabetisierung. Kombinatorik und Kontingenz Jean Pauls Leben Fibels, des Verfassers der Bienrodischen Fibel

Published: March 2019

Jean Paul's novel The Life of Fibel, Author of the Bienrodische Fibel places itself in a specifi c relation to literacy by identifying the alphabet and the spelling-book as a matrix of its own production. Thus, the text refers itself and its sense-effects back to the arbitrariness of its elements and their combinatorics. Moreover, at the margins of the book, it feigns to be abandoned to the contingency of its preliteral physis which is suppressed by sense, authority, authorship and control of the work.
Schriftkörper und Leseübung: Nietzsche als Stichwortgeber der Medien- und Kulturwissenschaft
Authors: Balke Friedrich
Published: March 2019

Als Philologe und Philosoph ebnet Nietzsche einer Konzeption der Ein-Schreibungen und ihrer Oberflächen, der Zeichenketten und ihrer Manipulationen den Weg, ohne die die gegenwärtigen Forschungen zu den medialen Gesten, Techniken und Dispositiven des Schreibens und Lesens nicht vorstellbar wären. Der Beitrag zeigt, dass und warum Nietzsches eigene Lese- und Schreibpraxis die Notationspraxis antiker hypomnemata erneuert: Aphorismen und Fragmente sammeln und ordnen das andernorts Gelesene und Gedachte, nicht um es kulturgeschichtlich in den Zeitraum seiner Entstehung einzuschließen oder es zum Gegenstand der Exegese zu machen, sondern um seine Reaktivierbarkeit in diskursiven Praktiken zu erproben, die das Subjekt an eine bestimmte Wahrheit binden.

As philologist and philosopher, Nietzsche paves the way for an understanding of inscriptions and their surfaces, of character strings and their manipulations, without which contemporary research on medial gestures, techniques and dispositives of writing and reading would not be conceivable. The paper shows that and why Nietzsche's own reading and writing revives the practice of ancient : his aphorisms and fragments collect and organize what Nietzsche read and thought, not in order to confine it to the timeframe of its genesis nor to make it an object of exegesis, but to test its potential of being reactivated in discursive practices that bind the subject to a certain truth.

Students are affected by their
social background, ethnic, geographic and cultural origin, languages spoken,
gender, sexuality, religion, etc. Also affecting students are the more general
social-political transformations (globalization, migration, changing labor
markets, etc.) Whereas a lot of the social science literature in education has
viewed these aspects of student identity
and diversity as separate from each other, I aim to understand how these
factors impact on student identities-work
intersectionally, especially in English Language Arts (ELA) classrooms. In the referenced

Psychometric Evaluation of the German Version of the Dietary Fat and Free Sugar – Short Questionnaire
Authors: Fromm Sophie Pauline , Horstmann Annette
Published: March 2019

Background: The Dietary Fat and free Sugar – Short Questionnaire (DFS) is a cost- and time-efficient self-report screening instrument to estimate dietary intake of saturated fat and free sugar. To date, only the English version has been psychometrically evaluated. We assessed the psychometric characteristics of the German version of the DFS in normal weight, overweight and obese individuals.Method: 65 adult participants completed a German translation of the DFS and a validated food frequency questionnaire (FFQ). We correlated participants’ percentage of energy intake from saturated fat and free sugar from the FFQ with the DFS scores. To establish test-retest reliability, participants completed the DFS a second time. To investigate convergent validity, we correlated participants DFS scores with self-reported eating behaviour and sensitivity to reward.Results: DFS scores correlated with percentage of energy from free sugar (rs = .443) and saturated fatty acids (rs = .258) but not with non-target nutrients. The correlation between DFS scores and percentage energy from free sugar was not moderated by BMI, whereas the correlation with percentage energy from saturated fat slightly decreased with BMI. Intra-class correlation was .801, suggesting excellent test-retest reliability. DFS scores correlated significantly with restraint of eating behaviour (rs = -.380) and feelings of hunger (rs =.275). Correlations of the DFS score with disinhibited eating and sensitivity to reward failed to be significant.Conclusion: Our results suggest that the German version of the DFS provides a reliable and valid estimation for the dietary saturated fat and free sugar intake of normal weight, overweight, and obese individuals.

Authors: Singh Anupam , Vathulya Madhubari , Mittal S. K. , Agrawal Ajai , Kumar Barun , Puthalath Athul S , Jamil Mahsa
Published: March 2019

Background: Foreign bodies of the orbit can have a diverse range of clinical presentations, which may be perplexing to the most Ophthalmologists. Wooden foreign bodies can remain quiescent for a long time, before presenting with various complications. We report a case of Post-traumatic chronic non-healing discharging sinus in the left upper lid, which on exploration revealed the presence of the missed wooden foreign body.

Case: A 48-year-old male, presented to Ophthalmic OPD with  a complaint of discharge from the left upper eyelid for 18 months. The patient had a history of minor trauma to the left upper eyelid while collecting wood in the forest, 18 months back. The patient was misdiagnosed on previous examinations elsewhere. The diagnosis of retained wooden foreign body was made at our center and surgical exploration was done to remove the same.

Observation: On clinical examination, there was a 2-3mm long sinus in the left upper eyelid with purulent discharge and granulation tissue. Surrounding skin showed hyperpigmentation and excoriation. CT scan orbit was inconclusive. MRI orbit revealed a peripherally enhancing extraconal/conal collection in the left orbit with a central hypo intense structure suggestive of a foreign body. Surgical exploration of the wound was done and a small wooden foreign body measuring 9mm was removed with excision of the sinus tract.

Conclusion: A history of trauma followed by chronic discharging sinus should evoke suspicion of a retained foreign body. Prompt imaging, followed by surgical exploration should be done to prevent misdiagnosis and inappropriate management.

Advances in the treatment of metastatic spine tumors: the future is not what it used to be
Authors: Laufer Ilya , Bilsky Mark H.
Published: March 2019

An improved understanding of tumor biology, the ability to target tumor drivers, and the ability to harness the immune system have dramatically improved the expected survival of patients diagnosed with cancer. However, many patients continue to develop spine metastases that require local treatment with radiotherapy and surgery. Fortunately, the evolution of radiation delivery and operative techniques permits durable tumor control with a decreased risk of treatment-related toxicity and a greater emphasis on restoration of quality of life and daily function. Stereotactic body radiotherapy allows delivery of ablative radiation doses to the majority of spine tumors, reducing the need for surgery. Among patients who still require surgery for decompression of the spinal cord or spinal column stabilization, minimal access approaches and targeted tumor excision and ablation techniques minimize the surgical risk and facilitate postoperative recovery. Growing interdisciplinary collaboration among scientists and clinicians will further elucidate the synergistic possibilities among systemic, radiation, and surgical interventions for patients with spinal tumors and will bring many closer to curative therapies.

Published: March 2019

Chickpea (Cicer arietinum L.) cultivar Royal (Reg. No. CV‐324; PI 673002), was released by the USDA‐ARS on the basis of its high yield and large seed size compared with the commercial chickpea cultivars Sierra and Nash. Royal was evaluated by the USDA‐ARS across 18 location‐years in Washington and Idaho receiving approximately 450 to 750 mm annual precipitation. Royal had an average yield of 1436 kg ha−1 across all trials, 5.4% less than Nash (1514 kg ha−1) and 7.3% greater than Sierra (1338 kg ha−1). Royal, similar to Sierra, has moderate resistance to Ascochyta blight. Royal was also tested by HighLine Grain Growers across 12 location‐years in Washington receiving approximately 300 to 350 mm annual precipitation. In these trials, Royal had an average yield of 1366 kg ha−1, 6.7% greater than Nash (1280 kg ha−1) and 23.7% greater than Sierra (1104 kg ha−1). In trials conducted by the USDA‐ARS 100 seed weight of Royal was 55.8 g, which was less than Nash and greater than Sierra. In trials conducted by HighLine Grain Growers, 100 seed weight of Royal was 52.0 g, which was not different than Nash and was greater than Sierra. Royal produced a greater percentage of “A” seeds (>8.7 mm) than Sierra in trials conducted by both the USDA‐ARS and HighLine Grain Growers. Royal is a promising alternative to Sierra as a high‐yielding large‐seeded chickpea cultivar, especially in regions receiving less than 450 mm annual precipitation.
Comfort or safety? Gathering and using the concerns of a participant for better persuasion
Authors: Hadoux Emmanuel , Hunter Anthony
Published: March 2019

Persuasion is an important and yet complex aspect of human intelligence. When undertaken through dialogue, the deployment of good arguments, and therefore counterarguments, clearly has a significant effect on the ability to be successful in persuasion. A key dimension for determining whether an argument is good is the impact that it has on the concerns of the intended audience of the argument ( e.g., the other participant(s) in the dialogue). In this paper, we investigate how we can acquire and represent concerns of a participant, and her preferences over them, and we show how this can be used for selecting good moves in a persuasion dialogue. We provide results from empirical studies showing that: (1) we can gather preferences over types of concern; (2) there is a common understanding of what is meant by concerns; (3) participants tend to make moves according to their preferences; and (4) the persuader can use these preferences to improve the persuasiveness of a dialogue.
The creation of an experimental longitudinal database of business micro-data
Authors: Zeli Alessandro
Published: March 2019

In recent years there has been an increasing need to extend the research potential of micro-level business data by allowing dynamic analyses via panel datasets. One option, using official statistics to build a firm level data panel, is to exploit archival data. However, an endemic problem with this approach is the management of firms transformational events: mergers, splits and spin-offs. This paper considers a way to address this problem. It describes the operative procedures utilized in building an experimental panel starting from firm-level databases available from the Italian National Institute of Statistics (Istat).

Total variation (TV) regularization-based iterative reconstruction algorithms have an impressive potential to solve limited-angle computed tomography with insufficient sampling projections. The analysis of exact reconstruction sampling conditions for a TV-minimization reconstruction model can determine the minimum number of scanning angle and minimize the scanning range. However, the large-scale matrix operations caused by increased testing phantom size are the computation bottleneck in determining the exact reconstruction sampling conditions in practice. When the size of the testing phantom increases to a certain scale, it is very difficult to analyze quantitatively the exact reconstruction sampling condition using existing methods. In this paper, we propose a fast and efficient algorithm to determine the exact reconstruction sampling condition for large phantoms. Specifically, the sampling condition of a TV minimization model is modeled as a convex optimization problem, which is derived from the sufficient and necessary condition of solution uniqueness for the L1 minimization model. An effective alternating direction minimization algorithm is developed to optimize the objective function by alternatively solving two sub-problems split from the convex problem. The Cholesky decomposition method is used in solving the first sub-problem to reduce computational complexity. Experimental results show that the proposed method can efficiently solve the verification problem of the accurate reconstruction sampling condition. Furthermore, we obtain the lower bounds of scanning angle range for the exact reconstruction of a specific phantom with the larger size.

Indonesia dengan kekayaan alamnya yang melimpah memuat aneka fauna unik hingga endemic (hanya dimiliki Indonesia). Sayangnya, seiring maraknya penangkapan hewan dan pembabatan atau pembakaran hutan secara liar dan illegal, banyak satwa milik Indonesia yang lantas menurun jumlahnya. Terlebih didorong oleh tingkat kelahiran hewan yang rendah, hewan-hewan tersebut akhirnya menjadi langka bahkan hamper punah. Pengenalan fauna kepada anak usia sekolah dasar (SD) sangat berpengaruh untuk membantu merangsang imajinasi dan kreatifitas. Teknologi Augmented Reality merupakan teknologi yang sedang berkembang dan menarik untuk mengenalkan beberapa jenis fauna kepada anak usia sekolah dasar. Untuk menunjang itu maka dibuatlah sebuah Aplikasi yang berjudul “Aplikasi Pengenalan Fauna Yang Dilindungi Menggunakan Augmented Reality Berbasis Android” yang dapat membantu dalam mengenal beberapa jenis fauna.
