Published: June 2019

Objectives: To determine the prevalence, types, clinical presentations, triggers, and predictors of allergic disorders among medical students and interns at King Abdulaziz University (KAU), Jeddah, Saudi Arabia.

Methods: A cross-sectional design was used for this study in which 600 medical students and interns were selected by a multistage stratified random sampling. A validated, confidential, selfadministered questionnaire was used during 2016 / 2017. It asked about the previous diagnosis of allergic disorders, associated factors, types, clinical symptoms and the triggering allergenic. Descriptive & inferential statistics were done and logistic regression analysis was conducted.

Results: The overall prevalence of diagnosed allergic disorder(s) among the participants was 36.2%.The commonest types of allergy were skin (33.8%) followed by respiratory (29.5%) presentations. The most frequently reported allergenic triggers were the house dust (45.6%) and smoke (30.4%). The first allergy predictor was family history of allergic disorders (aOR= 4.35, 95 % CI: 2.96-6.39), followed by female gender. Regarding the outcome of allergy on students’ life, 16.1% occasionally missed classes, and 28.6% had sleep disturbance during allergic attacks.

Conclusion: Allergy represents an important problem among medical students and interns. Family history and female gender were the predictors of allergy. Skin and respiratory allergies were the most common types. House dust and smoke were the commonest allergenic triggers. Detection of allergens and management of cases of allergy among medical students and interns are needed. Education and conduction of awareness campaigns about allergy are needed.

Published: June 2019

Objective: To evaluate the natural history of lumbar extruded disc with conservative treatment on MRI and to assess relation between the radiologic changes and clinical outcome.

Methods: This prospective observational study was conducted at University of Health Sciences, Diskapi Yildirim Beyazit Training and Research Hospital between May 2015-June 2018. It included consecutive patients who were diagnosed as having lumbar symptomatic extruded disc as shown in MRI. After an average period of 17.0±7.2 months, repeat MRI was taken in 40 patients who received only conservative care during follow-up. Changes in the volume of herniated disc was measured. The patients were assigned into 3 groups as follow: (1) non-regression, (2) partial-regression, and (3) complete resolution. Numeric Rating Scale (NRS) pain score, the Oswestry Low Back Pain Disability Index (ODI) and muscle weakness were evaluated.

Results: Based on disc volume of the T2-weighted MR images; four patients (10%) did not show any regression, six patients (15%) had a partial regression, and 30 patients (75%) had a complete resolution. Patients with complete resolution showed a significant improvement in the NRS pain score and the ODI score (p<0,001) over time. In patients with partial regression, only the ODI score improved significantly (p=0,043). Non-regression group did not show any improvement in any clinical outcome measure (p>0,05). Changes in the NRS scores over time were significantly higher in complete resolution group compared to non-regression group (p=0.016).

Conclusion: The majority of the patients with extruded lumbar disc herniation might have reduction in size of herniated disc in the long run along with improvement in symptoms and function with conservative care.

Data Analytics Supports Decentralized Innovation
Authors: Wu Lynn , Lou Bowen , Hitt Lorin
Published: July 2019

Data-analytics technology can accelerate the innovation process by enabling existing knowledge to be identified, accessed, combined, and deployed to address new problem domains. However, like prior advances in information technology, the ability of firms to exploit these opportunities depends on a variety of complementary human capital and organizational capabilities. We focus on whether analytics is more valuable in firms where innovation within a firm has decentralized groups of inventors or centralized ones. Our analysis draws on prior work measuring firm-analytics capability using detailed employee-level data and matches these data to metrics on intrafirm inventor networks that reveal whether a firm’s innovation structure is centralized or decentralized. In a panel of 1,864 publicly traded firms from the years 1988–2013, we find that firms with a decentralized innovation structure have a greater demand for analytics skills and receive greater productivity benefits from their analytics capabilities, consistent with a complementarity between analytics and decentralized innovation. We also find that analytics helps decentralized structures to create new combinations and reuse of existing technologies, consistent with the ability of analytics to link knowledge across diverse domains and to integrate external knowledge into the firm. Furthermore, the effect primarily comes from the analytics capabilities of the noninventor employees as opposed to inventors themselves. These results show that the benefit of analytics on innovation depends on existing organizational structures. Similar to the IT–productivity paradox, these results can help explain a contemporary analytics–innovation paradox—the apparent slowdown in innovation despite the recent increase in analytics investments.

Authors: Chadon Alphonsine Assemian Inès Christelle , Bouyahya Abdelhakim , Dakka Nadia , Bakri Youssef
Published: June 2019

Garcinia mangostana L. is medicinal plant. Its fruit, the mangosteen contains many bioactive xanthones. This study investigates the potential of organic leaf extracts of G. mangostana grown in Ivory Coast. We tested two organic leaf extracts: G. mangostana aqueous ethanolic leaf extract (ethanol: water, 80:20 v/v) (GMLE) and dichloromethane leaf extract (GMLD). We measured total phenolic and total Flavonoids. We analysed the in vitro anti-inflammatory, anti-radical and anti-proliferative activities of leaf extracts. Ethanol leaf extract showed a considerable amount of phenolic content (328.78±34.32 mg GAE/g) and moderate flavonoids content (43.60±1.48 mg QE/g), Dichloromethane extract had low values of phenolic (70.31±4.55 mg GAE/g) and flavonoids (8.49±0.69 mg QE/g). However, GMLD extract gave a significant anti-inflammatory activity (IC50=152.79±3.34 µg/mL), comparable to the standard drug diclofenac sodium (IC50=142.30±1.22 µg/mL), contrary to GMLE extract (IC50=652.33±12.23 µg/mL). The radical scavenging assay showed a very significant ability of ethanol leaf extract to reduce the DPPH radical (IC50=33.40±0.67 µg/mL) compared to references molecules such as Trolox (IC50=43.72±0.31 µg/mL) and acid ascorbic (IC50=27.20±0.17 µg/mL), dichloromethane extract results showed lowest activity (IC50 = 580.00±23.03 µg/mL). All the organic leaf extracts of G. mangostana had moderate anti-proliferative activity on L20B, RD and VS cell lines studied with IC50 values ranging from 110.89 ±4.82 µg/mL to 860.60±25.78 µg/mL). Our results prove the high potential of the G. mangostana leave extracts as anti-inflammatory and anti-oxidative stress drugs. However, further studies are to determine and validate all the medicinal properties of G. mangostana leaves extracts.

The current work aimed to screen for and identify protease-producing bacteria from the untapped resource Nasinuan forest, Kantarawichai District, Mahasarakham Province, Thailand. Nineteen bacterial isolates with protease-producing capacity on 1% skimmed milk agar were identified using 16S rRNA sequencing. Seventeen bacteria were gram-positive, rod shaped and identified as Bacillus spp. and only two bacteria were identified as Enterobacter sp. and Staphylococcus cohnii. Their closest relatives were found in India, Oman, Italy, Indonesia, Malaysia, China and USA. The top six highest halo : colony ratios from pure isolates were ranked in the following order: 1.2PT1 (2.43) > 1.2PT2 (2.23) > 2.2PT3 (2.21) > 2.1PT3 (2.17) > 2.3PT3 (2.16) > 2.4PT1 (2.16). Bacillus thuringiensis 2.3PT3 was found to exhibit the highest protease enzyme activity of 3.72 ± 0.08 U/mg protein at the optimal conditions of 65°C and pH 8.0 after 30 min incubation with 1% casein in 0.05 M PBS buffer. This protease–producing bacterial strain can be of great potential for applications in food, agricultural and pharmaceutical industries in Thailand.

The effects of Murraya koenigii leaves are very less studied in streptozotocin-nicotinamide (STZ-NA) induced diabetes rat model, in spite of several studies reported its antidiabetic effects in alloxan and STZ induced diabetes. The present study was undertaken to assess the effects of Murraya koenigii leaves extract on the blood sugar level (BSL) of STZ-NA diabetic rats. Experimental diabetes was induced by STZ injection intraperitoneally (i. p) after 30 min of NA injection i. p in all groups apart from normal control group. Group I (normal control) and Group II (diabetic control) rats received distilled water. Group III rats treated Metformin, Group IV and Group V rats treated Murraya koenigii aqueous extract and Murraya koenigii methanolic extract respectively. BSL and body weights of rats were measured at each week of the period of 28 days. Our results indicate that oral administration of Murraya koenigii reduces BSL significantly compared with the diabetic group. No weight loss was observed in all groups. The findings of the present study suggest that Murraya koenigii is proven as anti-diabetic agent in diabetic rats.

Published: June 2019

Diabetes mellitus, a chronic metabolic disease is increasing worldwide. Diabetic foot infections are one of the most feared and bothersome complications of diabetes caused by different genera of bacteria. There is an increasing evidence which demonstrates the presence of biofilm former's in chronic diabetic foot ulcers which contribute to the development of antibiotic-resistant strains and treatment failure. The present study aimed at isolating bacteria from diabetic wounds, to check for its antibiotic susceptibility and biofilm forming ability. From the diabetic wounds, isolates belonging to the genera of Staphylococcus, Pseudomonas, Klebsiella, Esherichia, Vibrio, Acinetobacter and Citrobacter were recovered. To the best of our knowledge, Vibrio parahaemolyticus was isolated for the first time from diabetic ulcer. Antibiotic sensitivity profile of the organisms infers the presence of multidrug-resistant strains. Majority of bacteria isolated were found to be biofilm formers. High biofilm former's were observed in strains of P. aeruginosa, S. aureus and Klebsiella spp. There was significant association between incubation time and intensity of biofilm formation in P. aeruginosa [ᵡ2 (p< 0.05) = 0.001)], Staphylococcus spp. [ᵡ2 (p< 0.05) = 0.023)] and Acinetobacter spp. [ᵡ2 (p< 0.05) = 0.018)]. The presence of biofilm forming multidrug-resistant bacteria infers the chronic nature of diabetic wounds.

Authors: Bikbulatova Albina Ahatovna
Published: June 2019

In modern society, obesity in women in developed countries retains its widespread prevalence. Much attention to this problem is caused by the current increase in the number of cases of obesity among middle-aged women who are not able to regularly experience muscular loads in the form of exercises and comply with various dietary restrictions. In this regard, there is a need for cosmetic correction of their figure in the presence of minimal effort on the part of women with signs of obesity. The solution to this problem may be the wearing of corrective clothing, which is able to effectively reduce the volume dimensions of the body through a soft mechanical impact on it in problem areas. In the work carried out, the safety assessment of the long wearing of the author's version of the trousers was carried out taking into account the dynamics of the plasma level of functionally significant hemostasis biregulators for half a year. It was found that women with obesity 1 degree, wearing corrective clothing, there was a persistent preservation of the indicators taken into account within the normal range. The great advantage of using the author's version of corrective clothing for women with obesity was the upcoming visual reduction of their body sizes in the area of ​​application of the product. At the same time, all women under observation maintained a consistently normal plasma level of hemostasis regulators corresponding to the control values. The results obtained allow us to consider the author's corrective clothing as a complete and safe component of the visual correction of the manifestations of developing obesity in women.

Published: June 2019

Treatment of epilepsy is quite challenging as it requires the antiepileptic drugs to be taken for a long duration, sometimes throughout the lifetime of the patient. But such chronic drug intake results in adverse effects, drug interactions and added economic and emotional distress to the patients. It is therefore of utmost importance to analyze the pattern of prescription of antiepileptic drugs, the concurrent medications in epilepsy. The present study was conducted to collect, assess and understand the above data and also to analyze the rationality and correctness of prescription using the WHO prescription indicators. A total of 100 case records of patients diagnosed with epilepsy was analyzed and the data was recorded. We have total 34 children and 66 adult patients in our study. Generalized tonic-clonic seizures was the common type of seizure. Phenytoin was the most commonly prescribed antiepileptic drug. 1/3rd of the patients needed more than one drug for adequate seizure control and the most common add on drug was levetiracetam. Also, the average number of drugs prescribed to the patients was 6 which included drugs given for concomitant illnesses as well. A total of 561 medicines were prescribed which included the drugs prescribed for concomitant illnesses as well. Average number of medicines per prescription was 6. Prescription by generic name was seen in 42% of the cases. An injection was prescribed in 66% of the prescriptions. An antibiotic was encountered in 38% of the prescriptions. Most of the epileptic patients are subjected to polypharmacy which puts them at a higher risk of side effects, drug interactions and financial burden. Physicians should minimize the use of drugs and look into the rationality of each prescription.

Published: June 2019

Due to continuous debate of incompatible results of blood pressure by the two devices such as the automated oscillometer and the traditional mercury sphygmomanometer, a study was carried out to compare the accuracy of the two devices as well as the best position to measure blood pressure. A comparative study regarding the difference in values of BP (mmHg) between traditional auscultatory method and automated oscillometric readings in supine and sitting positions was conducted among medical students. Oscillometer produced high readings than the readings of sphygmomanometer. Besides, the blood pressure readings for systolic and diastolic are higher while sitting when compared to supine position as the blood is unevenly distributed to all part of the body in sitting position. This will lead to the increase in ionotropic effect of the heart to pump blood towards the upper part of the body. The differences between two methods showed there have a major problem or error in measuring blood pressure. It is therefore necessary to improve the method and ways to check the health especially in this area where slight differences may contribute to large errors.

Human papilloma virus (HPV) is the most important cause of cervical cancer that is infected among young and sexually active individuals and rated as third most common cancer. The aim of this research was to determine the perception regarding HPV vaccination among the MBBS students of UniKL RCMP. Descriptive cross-sectional study was done among 207 respondents from MBBS students of UniKL RCMP where a set of questionnaire was given that contains 38 questions. The sections were assessed their socio demographic input, knowledge, attitude and practice scores respectively. Descriptive statistics in terms of frequency and percentage, and cross tabulation were used to analyze the association of knowledge, attitude and practice. Pearson chi square was used to test the hypothesis. There was no association between gender and knowledge regarding HPV vaccination and between year of study and attitude regarding the HPV vaccination. However, gender had a statistical significance with attitude and was also a statistical significance between year of study and knowledge on HPV vaccination. It was concluded from the results that gender does not play a role in knowledge regarding HPV vaccination, but year of study does. However, gender plays a role in attitude on HPV vaccination.

Published: June 2019

Excessive exposure of UV light increase melanin synthesis and cause hyperpigmentation of the skin. The pharmacological activity of secang (Caesalpinia sappan L.) with the main compound, brazilien and brazilin as antioxidants that have potency as free radicals scavenger and directly inhibit tyrosinase activity in the process of melanogenesis. This study aims to determine the inhibitory ability of secang ethanolic extract on tyrosinase enzymes in vitro and evaluate the affinity of brazilein and brazilin as skin depigmentation agents against melanogenesis target protein in silico using molecular docking. In vitro testing using tyrosinase inhibitor assay with L-DOPA as its substrate and calculated the percentage inhibition value and IC50. The IC50 of the extract than compared with the positive control, namely kojic acid and ascorbic acid. Insilico research was carried out using autodock 4.2 program by evaluating the binding energy between the active compound of brazilein and brazilin with melanogenesis protein. Inhibition of the tyrosinase enzyme is showed through the IC50 value from ethanolic extract, kojic acid and ascorbic acid respectively 104 μg/ mL, 44 μg/mL and 37 μg/mL. Binding energy of the molecular docking process between brazilein, brazilin, kojic acid and ascorbic acid with the target protein of melanogenesis enzymes (tyrosinase, tyrosinase related protein 1, and D-Dopachrome tauomerase) are -8.37; -6.56; -5.03; -5.35 kcal/mol in tyrosinase, -7.75; -6.40; -5.32; -5.8 kcal/mol in tyrosinase related proteins 1 and -9.93; -8.26; -5.8; -6.52 kcal/mol in D-Dopachrome tautomerase. Secang ethanolic extract could be developed into a skin lightening agent or depigmentation agent through inhibition of 3 target proteins that induce melanogenesis. Although invitro results show the inhibitory ability of the tyrosinase enzyme is lower than kojic acid and ascorbic acid but in silico, it is seen that brazilein and brazilin in secang ethanolic extract have a stronger affinity compared to kojic acid and ascorbic acid. For this reason, it is necessary to purify the extract into a fraction so that it can get more active ingredients of brazilein and brazilin, and in vitro testing for inhibition of the tyrosinase related protein 1 enzyme, and D-Dopachrome tautomerase.

Tomassetti’s masculinity
Authors: Quinn Hannah
Published: July 2019

In our current society women are increasingly being accepted as both creators and consumers. In the face of female empowerment, we must be willing to re-examine our relationship to masculinity. As women are no longer seen as ‘lacking’, there is an increasing call for men to be allowed to embody traditionally feminine traits. Written through the lens of psychoanalysis, this article examines the way in which the artist Alessandro Tomassetti subverts our expectations of masculinity in his painting of a young man in a lace glove titled The Big Time (2015).

A natureza do fenómeno da reputação científica: o caso dos consórcios universidade-indústria
Authors: Ruão Teresa , Pessôa Clarisse
Published: July 2019

A reputação é um fator muito influente no trabalho de um cientista pelos seus efeitos na carreira, captação de fundos ou aprovação dos pares. Do mesmo modo que se revela importante para as unidades de I&D na construção de redes de trabalho e na angariação de financiamento, público ou privado. Contudo, o fenómeno da reputação é difícil de avaliar, pois inclui fatores subjetivos, não detetados nas habituais técnicas bibliométricas, e porque tem evoluído face às exigências da nova ciência-empreendedora.Neste contexto, desenvolvemos um estudo com o propósito de entender a natureza do fenómeno da reputação aplicado ao domínio da ciência, no ambiente de um consórcio de investigação universidade-indústria em Portugal. Trata-se de uma investigação-piloto que partiu das necessidades sentidas pela equipa de comunicação do consórcio e que tem em mãos a tarefa de gerir a reputação da parceria e dos seus investigadores. Esse artigo deixa algumas pistas para um trabalho de Comunicação Estratégica continuado.
A Publicidade face aos novos contextos da era Digital: privacidade, transparência e disrupção

Published: July 2019

O tempo que corre está a complexificar-se extraordinariamente onde justamente julgávamos que se iria tornar mais transparente. A Internet e a economia digital estão a tornar-se cada vez mais um verdadeiro “data industrial complex”, uma caixa de Pandora de consequências insondáveis. O que se passa com a publicidade digital é apenas um esboço do problema, sendo certo que as primeiras consequências estão aí à vista no sistema de media, que continua a sufocar por falta de receita e de tráfego na web. Este texto é um contributo para aprofundar esta reflexão.

Published: July 2019

O rádio brasileiro, inserido na nova ecologia de mídia, enfrenta desafios de ordem diversa assumindo diferentes configurações frente ao cenário de constante desenvolvimento tecnológico. Dado o contexto, este artigo volta seu olhar para o posicionamento no Facebook de três emissoras radiofônicas jovens brasileiras, a saber: Rádio Mix, Rádio Jovem Pan e Rádio Transamérica. Utilizando a metodologia de Análise de Conteúdo em Redes Sociais e o estudo de caso comparativo (Yin, 2001), o objetivo é compreender as principais estratégias de postagem e engajamento usadas pelas emissoras para captar a atenção da audiência nas redes sociais. Os resultados apontam para a falta de estratégia e o baixo engajamento nas fanpages. Nenhuma das emissoras analisadas constrói um efetivo processo de interação em suas redes sociais, predominando a participação, característica do rádio jovem dos anos 1990.

Published: July 2019

Este artigo compõe uma etapa da cartografia que estamos realizando, e que possui como tema as transformações no campo da publicidade, e inclusive de seus modelos de negócios. Utilizamo-nos de duas técnicas de produção de dados (estado da arte e entrevistas semi-abertas) e analisamos os elementos coletados, a partir da obra de Deleuze e Guattari (1995), com o conceito de rizoma, para que fosse possível traçar o nosso próprio objeto, o campo da publicidade em transformação, de forma rizomática. Este artigo responde ao seguinte questionamento: Quais os principais platôs que compõem os tensionamentos no campo da publicidade e suas reformulações atuais? Após as análises, além do debate frutífero acerca do conceito de rizoma, foi possível identificar os tensionamentos atuais que levam o fazer publicitário a ser questionado e revisado, bem como, possibilitou o início da construção rizomática de nosso objeto de pesquisa, o que pretendemos expandir com incursões futuras.

Authors: Abdullah Rahma Hashim , Fadhil Iman , Oda Amjed Mirza
Published: June 2019

Green synthesis route has been used for preparation of silver nanoparticles (AgNPs) by aqueous extract of chard plant (Beta vulgaris). The extract volume was studied as effected parameter in the synthesis of AgNPs and monitored by UV-visible spectrum according to the surface plasmon resonance band that centered at 417 nm. The silver nanoparticles were characterized by FTIR, XRD and SEM. The FTIR anlysis showed the adsorption of biomolecules on the AgNPs surface acting as reducing and capping agent. The XRD results revealed the presence of cubic face silver metal without trace of another silver oxides, as an indication of stability against oxidation. Also XRD in combination with SEM analysis showed that AgNPs are in the nanometric scale with spherical identical shape, where the route was successful. The silver nanoparticles tested against Streptococcus pneumonia and Escherichia coli, where the inhibition zone was 28 and 33 nm, respectively.

Authors: Elysabeth Tiur , Zulnovri  , Ramayanti Gina , Setiadi  , Slamet
Published: June 2019

This study aimed to apply the TiO2-zeolite composite material as a photocatalyst in the photodegradation of ammonia gas. TiO2-Bayah natural zeolite was synthesized by slurry method and continued with calcination process at 500 °C for 3 h. The amount of TiO2 varied (5, 10 and 20 % wt) in the total weight of the catalyst to prove the effect of TiO2 loading on the composition, structure and surface area of the composite, as well as the efficiency of ammonia gas degradation. X-ray fluorescence characterization showed the increasing of TiO2 composition of composite materials according to the amount of TiO2 loaded. X-ray diffraction showed that there was no change in the structure of the zeolite before and after combination with TiO2. BET analysis showed that the composite surface area was larger than the zeolite surface area, but the surface area decreased with increasing TiO2 loading. Performance test results showed that TZ5 (5 % TiO2-zeolite) degraded ammonia gas better than other samples.

Published: June 2019

Impregnation of mesoporous silica MCM-41 on metal organic framework type HKUST-1 or often called CuBTC (BTC = 1,3,5-benzenetricarboxylate) has been successfully carried out by solvothermal methods in a solvent mixture of water, ethanol and N,N-dimethylformamide (DMF). The XRD patterns of the obtained solids showed that MCM-41/HKUST-1 composites had the same crystalline phase as pure as HKUST-1. SEM images revealed that the impregnation of the mesoporous silica to HKUST-1 did not alter the surface morphology of the original HKUST-1, which had octahedral shapes. In addition, the thermal stability of the MCM-41/HKUST-1 composites reached 302 °C, increased by 292 °C in comparison to the HKUST-1, even though the impregnation process resulted in a decreased in the specific surface area of the composites. Furthermore, MCM-41/HKUST-1 composites showed outstanding performance as adsorbent of methylene blue and Congo red in aqueous solutions. Results of adsorption studies showed that a pseudo-second order kinetics and Langmuir isotherm were observed for both types of dyes.

Message of Hilal Son Prince Badr Hasnawy About Imprisoning His Father
Authors: Abdullah Kamaran A.
Published: June 2019

Hilal Bin Badr published his noted message after imprisoning his father. The brutality of his illegitimate action gave birth to a lot of resentment among the people. This research is divided into two sections. In the first section, we spoke about the reasons for the spread for Hilal’s message by shedding light on two matters. In the first point, we explained the reaction of people towards (Hilal) and its effect on the spread of his letter. While in the second point we spoke about the credibility, prestige, and legitimacy of the prince (Badir). We pointed out the populace and the Abbasid Caliph had held Prince Badr with high esteem. In the first part of this section, we spoke about the manipulation of religion by (Hilal) to legitimate his coup against his father. and in the second part we pointed out the extent to which (Hilal) has gone by attributing an exaggerated image of himself and drawing a negative and unauthentic picture of the prince (Badr). It became obvious to us that this accusation was against of what historians and historical sources that mentioned prince (Badir) respectfully and for being innocent from this accusation.

Hume’s Answer to Bayle on the Vacuum
Authors: Cottrell Jonathan
Published: July 2019

Hume’s discussion of space in the Treatise addresses two main topics: divisibility and vacuum. It is widely recognized that his discussion of divisibility contains an answer to Bayle, whose Dictionary article “Zeno of Elea” presents arguments about divisibility as support for fideism. It is not so widely recognized that, elsewhere in the same article, Bayle presents arguments about vacuum as further support for fideism. This paper aims to show that Hume’s discussion of vacuum contains an answer to these vacuum-based fideistic arguments. Key to this answer is a distinction between two ways in which vacuum was conceived in the early modern period: i) as a genuine thing that has spatial properties, and yet is immobile, indivisible, and penetrable (positive vacuum); ii) as a mere absence of spatial things (privative vacuum). This paper also aims to provide a novel defense of Hume against the long-standing objection that he is inconsistent in denying that we can conceive of a vacuum, while allowing that we can conceive of “invisible and intangible distance.” As I interpret him, Hume consistently denies that we can conceive of a positive vacuum, while allowing that we can conceive of two or more objects’ being arranged so as to have privative vacuum between them.
Collateral and development

Published: June 2019

This paper presents a model economy with endogenous credit constraints à la Kiyotaki-Moore and endogenous growth à la Uzawa-Lucas, in which agents face a trade-off between investing resources to improve the pledgeability of collateral assets and the accumulation of human capital. The model generates both growth miracles and stagnant economies.
