Published: July 2020

El presente estudio analiza las diferencias en la calidad de vida de los adultos mayores (AM) a partir de los factores sociodemográficas y percepciones respecto a la salud, trabajo y familia. La muestra fue 817 AM de zonas rurales y urbanas del Guayas. Se usó el método de encuesta a través de un cuestionario que contiene las escalas debidamente validadas. Las variables continuas se compararon con pruebas t y las categóricas con U Mann-Whitney. Adicionalmente se realizó una regresión múltiple por pasos para verificar las relaciones entre la calidad de vida y sus factores asociados. Los resultados mostraron que los factores asociados a la QoL difieren según la zona residencial. Los habitantes rurales otorgan alto nivel de importancia a la salud y familia mientras que la educación no es un factor determinante de su  QoL. En la zona urbana es importante tanto la salud y familia como el nivel educativo y cantidad de bienes. El nivel de QoL de los AM no obedece a que estén ocupados en ningún caso.

The purpose of this study is to describe the impact of children's productive activities in the sand mine on dropout rates at the junior high school level in Keduwang Village, Blitar Regency. Respondents of the research data amounted to 38 children who carried out productive activities of sand mining. This study used cross-sectional survey research method with a quantitative approach that were supplemented with qualitative data. The collection technique used questionnaire, observation, and interviews. Data analysis techniques used descriptive data analysis techniques with the odds ratio method. The results indicate that the impact of children's productive activities in sand mining on dropout rates at junior high school level with decrease of children’s interest attending school. The results of odd ratio analysis indicate that the riskiest factor causing children to choose school dropout is productive activities in sand mining do not require special skills. The factor of not requiring special skills is proven to be six times the risk of causing children school dropout. The results provide description of how easy economic access and does not require skills has an impact on children's perceptions of going to school or working. Implications for the results of this research are expected to be a reference for government to pay attention to dropout rates that occur due to the productive activities of children in sand mining.

A Mathematical Study on a Diseased Prey-Predator Model with Predator Harvesting
Authors: Thota Srinivasarao
Published: July 2020

In this paper, we present a mathematical model for a prey-predator system with infectious disease in the prey population. We assumed that there is harvesting from the predator and a defensive property against predation. This model is constituted by a system of nonlinear decoupled ordinary first order differential equations, which describe the interaction among the healthy prey, infected prey and predator. The existence, uniqueness and boundedness of the system solutions are investigated. Local stability of the system at equilibrium points is discussed.

Published: July 2020

This paper deals with law and Islamic court in the period of Prophet an Khulafā’ Rāshidun. In the period of Prophet, law was not widely interpreted since the Prophet was the only source at that time. There was also also no building for the court, but dispute resolution was held in the mosque. In the period of Khulafā’ Rāshidun, especially in ‘Umar’s period, there was a separation betweem legislative, executive, and judicative bodies. There was also building for court, in ‘Uthman’s period, and salaries were given to the judges from Bayt al-Mal. In. ‘Ali’s period, administration of justice began to be independent in solving the case.

FDI & economic growth in selected Country groups for (1989-2018)
Authors: Hassan Khalil Gh.
Published: July 2020

Theoretically, it is heavily believed that FDI is as a source of development, modernization, income, and employment growth and that FDI boosts the productivity of host countries and promotes economic growth. This paper examines, within a growth theory framework, the role which foreign direct investment (FDI) plays in the growth process in the context of different income group countries characterized by their per capita income. The paper tests (using time series data relating High, Middle- and Low-income countries) the hypothesis adopted is that FDI, enhance economic growth. The estimated indicators show evidence of rejecting Null hypothesis in the case of High- and Middle-income group countries but, vice versa the Null hypothesis is accepted for Low-income group countries.
Reduction of O2 to H2O2 using Small Polycyclic Molecules
Authors: Lopez Kristal , Groves Michael
Published: July 2020

Hydrogen peroxide is an environmentally friendly oxidizing agent that is important in several industries. It is currently produced industrially via the anthrahydroquinone (AHQ) process where O2 reacts with a functionalised version of anthrahydroquinone to produce H2O2 and anthraquinone. In the previously published DFT pathway for this process the transition of the OOH? radical across the partially dehydrogenated AHQ catalyst was not explored. In this paper, we will use DFT to explore this step and show that there is a deep potential energy minimum that inhibits the OOH. from being fully reduced. We then examine other similar sized polycyclic molecules with two OH-groups on the same side that could serve as alternative catalysts without this issue. In this analysis, we identify Phenanthraquinone as a possible alternative and present the pathway for this candidate to produce H2O2 as well as its regeneration with H2.

Authors: Chandrasekar MJN  , Raman Rajeshkumar  , Arivukkarasi Varadharajan
Published: July 2020

Several carboline derivatives are anticancer agents and studied for antiproliferative action against various cancer cells. Based on the preliminary analysis using insilico strategies, we have selected eight compounds for the study. All compounds have been synthesised and characterised for their purity and chemical composition. Antiproliferative activity was assessed by insilico Carcinogenicity assay, Cytotoxicity analysis by sulphorhodamine B, Antiproliferation assay and DNA damage analysis. The cytotoxic effects of the CH5, CH17, CH29, CH34, CH37, CH39, CH42 and CH47 on Vero, HeLa, A549, BRL3A, HCT116, and MCF7 were determined using the SRB assay. CH5, CH34, CH37 and CH42 was the most potent cytotoxic towards HCT116 cells with CTC50 value of 62.1±0.19, 47.1±0.41, 78.5±1.26 and 32.1±1.11 µg/ml respectively. The assay revealed a noticeable reduction in cell number for CH5 and CH37 tested except CH34 and CH42. CH5 and CH37 observed cytotoxic effects were found to destroy the cells according to time, and cell viability decreased with that time length. To learn their role in cell death, CH5 and CH37 were therefore taken up for a further screening. This study suggested that CH5 and CH37 had a separate mechanism of action to kill and that in the cell line. Such results will provide enrichment of scientific knowledge on the molecular mechanism and target therapies of CH5 and CH37, thereby potentially helpful for patients with Colon cancer.

Published: July 2020

Cancer is treated effectively by means of currently available medical knowledge and equipment for therapy. Still, earlier diagnosis of cancer is a crucial factor to determine the probabilities of a cancer patient for survival. Cancer must be identified at least before the stage of metastasis. Another significant aspect is the develop an efficient targeted drug delivery system, which can reduce the occurrence of side effects for achieving an effective patient therapy. Nanomedicine approach can be utilised for diagnosis, treatment and preventing various diseases by using molecular tools and molecular knowledge of human body. By using nano-structured materials and simple nanodevices which can be manufactured, nanomedicine can address various medical problems. Within few decades’ technology assisted medicine and particularly robotics will have a significant impact. Surgeon’s motor performance, diagnosis capability etc. can be augmented by robots. Nanorobots can navigate as blood borne devices and thus it has an extremely important role in treatment of cancer. For diagnosing of cancerous cell inside the patient’s body at its earlier development stages, chemical biosensor embedded nanorobots can be used. To determine the E-cadherin signals intensity, integrated nanosensors may be utilized. The aim of the present article is to explore the future nanorobotic’s use to fight cancer and, their designing and architecture
Pain and social decision-making: New insights from the social framing effect
Authors: Gu Ruolei , Liu Jie , Cui Fang
Published: July 2020

This paper focuses on the social function of painful experience as revealed by recent studies on social decision-making. Observing others suffering from physical pain evokes empathic reactions that can lead to prosocial behavior (e.g., helping others at a cost to oneself), which might be regarded as the social value of pain derived from evolution. Feelings of guilt may also be elicited when one takes responsibility for another’s pain. These social emotions play a significant role in various cognitive processes and may affect behavioral preferences. In addition, the influence of others’ pain on decision-making is highly sensitive to social context. Combining neuroimaging techniques with a novel decision paradigm, we found that when asking participants to trade-off personal benefits against providing help to other people, verbally describing the causal relationship between their decision and other people’s pain (i.e., framing) significantly changed participants’ preferences. This social framing effect was associated with neural activation in the temporoparietal junction (TPJ), which is a brain area that is important in social cognition and in social emotions. Further, transcranial direct current stimulation (tDCS) on this region successfully modulated the magnitude of the social framing effect. These findings add to the knowledge about the role of perception of others’ pain in our social life.

Authors: Solís-Carcaño Rómel Gilberto , Chan-Magaña Gerardo Enrique
Published: July 2020

La abrasión es una importante acción mecánica que afecta a los elementos de concreto que soportan tránsito intenso o conducen líquidos. Los factores que más influyen en la resistencia a la abrasión de este material son la dosificación de la mezcla, la resistencia de los agregados, el acabado y el curado. En muchas partes del mundo se utilizan agregados de roca caliza, los cuales son, por lo general, más porosos que los provenientes de las rocas ígneas. El objetivo de esta investigación fue determinar el efecto en el desgaste por abrasión de la relación A/C, el curado y la sustitución parcial de agregado fino calizo. Se concluyó que el concreto con relación A/C de 0.40 es adecuado para obtener concretos de alta exigencia a la abrasión, y se probó estadísticamente la influencia del curado y de la sustitución parcial de agregado fino con otro de menor absorción.

Susceptibility of Economic Dipteran Fruit Flies to Entomopathogenic Nematodes
Authors: Tawfik Abbas Mohamed Samir
Published: July 2020

The present review article demonstrates laboratory and field evaluations of entomopathogenic nematodes (EPNs) against different developmental stages of fruit flies. The virulence of the EPNs  differed clearly  even on the same insect species and / or by the same nematode species. Such differences might be attributed  to some reasons such as the method of treatment as well as the concentrations of the tested nematodes. Fruit flies are among the most important insect pests infesting vegetables and fruits causing considerable losses in the yields worldwide. In laboratory studies, the tested nematodes proved to be highly virulent to larvae as  percentage of  mortality may reach 100 %.  As for treated pupae, at different ages, the results are variable and controversially; some studies revealed their moderate or high susceptibility to nematode infection and others indicated low susceptibility or resistance to infection .Treated adults, or those emerged from treated larvae or pupae,  are also susceptible to infection.  In semi-field and field trials, EPNs proved to be successful for reducing the populations of some fruit flies with up to 85 % at concentrations not less than 100 infective juveniles (IJs) / cm2 of soil. However, the field applications of commercial EPNs have been recommended to be 2.5 – 5 x 109 IJs / ha (25-50 IJs/cm2 of soil).

Authors: Saleh Hamed H.E.
Published: July 2020

No or little information on the use fresh (wet) housefly maggots (Musca domestica) in African catfish (Clarias gariepinus) fry feeding. Therefore, this study was conducted to investigate the effect of feeding on fresh (wet) housefly maggots with or without artificial diet on water quality, growth performance, survival percentage and feed utilization of African catfish fry under laboratory conditions. Housefly maggots produced from a mixture of poultry droppings and foods wastes, it was used to replace artificial feed at 0, 50 and 100% levels. Catfish were fed artificial diet alone (Feed 1), fresh (wet) housefly maggots alone (Feed 2), and 50% fresh housefly maggots with 50% artificial diet (Feed 3) were prepared and tested on triplicate groups of African catfish fry (initial weight of 0.25±0.02 g) for 60 days. Results showed that final weight (g/fish) was significantly highest (P£0.05) in fish fed feed 3 (6.03±0.08), followed by fish fed feed 2 (4.62±0.27), followed by fish fed feed 1 (3.15±0.68). Specific growth rate (%/day) was also significantly highest in fish fed feed 3 (5.31±0.10), followed by fish fed feed 2 (4.86±0.03), followed by fish fed feed 1 (4.18±0.24). The same trend was observed with total weight gain, percentage weight gain, daily growth rate and relative growth rate. Feed intake and protein intake were significantly highest (P£0.05) in fish fed feed 3 and fish fed feed 2, followed by fish fed feed 1. While, feed conversion ratio (FCR) and protein efficiency ratio were not significantly (P>0.05), but the improvement in FCR recorded in catfish fry fed feed 3 and feed 2 under the experimental conditions. Survival percentage was within the range 55–75%, with insignificant differences (P>0.05) among treatments. The water quality parameters such as temperature, pH, dissolved oxygen, total ammonia, nitrite and nitrate were not significantly (P>0.05) among the treatments and were tolerable for fish culture. Accordingly, use of the 50% fresh (wet) housefly maggots with 50% artificial diet in African catfish fry feeding had positive effect on growth performance and reduce of the feed cost.

A Discussion for the Protection of the Environnement in the Law of Planification in China
Authors: Zhang Li
Published: July 2020

This article aims to answer the question that if the law of planification of China, really takes account of the objectives of environmental protection. The answer is based on, first of all, the reform of system of land ownership (direct link of the development of urbanization). This article cracks the problem by two approaches: the state and collective property right. The first part of the analysis is macro-perspective, i.e., the course of land reform and the land users. In general, the state remains the sole owner of all the land and delegates the local governments to manage the use of land in China. However, the high interest undermines their roles, and degradation of environment in the process of urbanization continues. Based on this observation, we analyzed their administration, i.e., who are the actors and how the powers are shared. The lack of transparency and independence is in its structure, i.e., they have ambitions to have a good protection but the conflict appears frequently. In the further part, micro-vision was employed. We focused on the regulations of planification, procedures and formalities that is deeply involved. In fact, we find that the volume of law was expanded and a need of consolidation is urgent for the coherence, accessibility and understanding of law. Then it follows the analysis of two typical procedures: the procedure of environmental assessment as well as participation. These procedures are the practical implementation of the consideration of the environment. The fact is that rapid urbanization resulted in a reconfiguration of the urban space, and the appearance of a variety of interests. The degradation of environment, coupled with the importance of urbanization has become a challenge to governance. People realized more and more issues related to housing, welfare and citizenship. This forces the government to change their policies and acts. From different points of views- historical, political, administrative, legal and social- this research determines how a better environmental protection can play in law of planification. The reforms are envisaged, and there are still problems: the harmonization and consistency of the regulations, the clarity of the law for his efficiency and law security, the improvement of the process. Contrary to what is received, the government has intention to solve this question, as demonstrated by his consistency to innovation and reform in the field. At the present, planification, rather than a method of protection, works for the growth of the economy. Due to the lack of effective regulation, the real consideration of environment is still very limited.

Published: July 2020

The unexpected seroconversion of sentinel mice in our facility to murine T lymphotrophic virus (MTLV) positivity led to our identification of a novel murine astrovirus that we designated murine astrovirus 2 (MuAstV-2). During our investigation, MuAstV-2 was found to be a contaminant
of the T helper cell line (D10. G4.1) that was used to generate the MTLV antigen that we included in the multiplex fluorometric immunoassay (MFIA) that we used for sentinel screening. We eventually determined that cross-reactivity with the astrovirus generated a positive result in the MTLV
assay. A confirmatory immunofluorometric assay (IFA) using the same MTLV-infected cell line yielded a similar result. However, the use of antigen prepared from MTLV-infected neonatal mouse thymus did not reproduce a positive result, leading us to suspect that the seroreactivity we had observed
was not due to infection with MTLV. A mouse antibody production test showed that mice inoculated with naïve D10. G4.1 cells and their contact sentinels tested positive for MTLV using cell-line generated antigen, but tested negative in assays using MTLV antigen produced in mice. Metagenomic
analysis was subsequently used to identify MuAstV-2 in feces from 2 sentinel mice that had recently seroconverted to MTLV. Two closely related astrovirus sequences (99.6% capsid identity) were obtained and shared 95% capsid amino acid identity with the MuAstV-2 virus sequenced from the D10.
G4.1 cell line. These viruses are highly divergent from previously identified murine astroviruses, displaying <30% capsid identity, yet were closely related to murine astrovirus 2 (85% capsid identity), which had recently been isolated from feral mice in New York City. A MuAstV-2 specific
PCR assay was developed and used to eradicate MuAstV-2 from the infected colony using a test and cull strategy. The newly identified MuAstV2 readily transmits to immunocompetent mouse strains by fecal-oral exposure, but fails to infect NOD-Prkdcem26Cd52Il2rgem26Cd22/NjuCrl
(NCG) mice, which have significantly impaired adaptive and innate immune systems. Neither immunocompetent nor immunodeficient mice showed any astrovirus-associated pathology. MuAstV-2 may provide a valuable model for the study of specific aspects of astrovirus pathogenesis and virus-host interactions.

Perioperative complications and deaths occurred while developing a novel surgical model of pediatric kyphosis in 10 to 12 kg male farm-raised Yorkshire piglets. All piglets appeared clinically normal preoperatively. Intraoperative complications included tachycardia, respiratory acidosis,
and death. Postoperatively, clinical signs included posterior paresis, head pressing, prolonged anesthetic recovery, difficulty rising, and sudden death. Necropsies were performed on all piglets. Some morbidity and mortality were accurately attributed to the spinal surgery. However, the index
piglet for this report died suddenly approximately 16 to 18 h after surgery. Necropsy of this animal revealed clear, serosanguineous pleural and pericardial effusions along with myocardial hemorrhage and hepatic lesions, consistent with mulberry heart disease and hepatosis dietetica, respectively.
Serum vitamin E and selenium levels from this animal were below age-specific lab reference ranges. Clinical signs of vitamin E and selenium deficiency are most common in fast-growing weaner piglets. The added stress of major surgery may exacerbate the condition in young piglets. Resolution
of morbidity and mortality in both juvenile and adult pigs occurred upon the use of an alternate vendor able to provide feed analyses meeting industry standards, although serum levels of vitamin E and selenium in similar ages and breed of swine were still occasionally slightly below reference
ranges.

Tükenmişlik konusu uzun zamandan beridir yönetim-organizasyon ve eğitim yönetimi alanlarında en çok çalışılan konulardan biridir. Bu çalışmada, Türkiye’de eğitim örgütlerinde yapılan tükenmişlik makaleleri ile ilgili bir değerlendirme yapılması amaçlanmıştır. Araştırma nicel ve nitel araştırma desenlerinin bir arada kullanıldığı tarama modelinde bir araştırmadır. Araştırma kapsamında 1995 ile 2019 yılları arasında yayınlamış olan 193 makale incelenmiştir. İncelenen kaynaklar doküman incelemesi yöntemiyle elde edilmiştir. Verilerin analizinde içerik analizi teknikleri kullanılmıştır. Son yıllarda tükenmişlik konulu makalelerin sayısında belirli bir artış vardır. Makaleler çoğunlukla Türkiye adresli dergilerde yayınlanmış, Türkçe ve bir ya da iki yazarlı olarak hazırlanmıştır. Makalelerin büyük çoğunluğu ilişkisel tarama ve genel tarama modelinde hazırlanmıştır. Makalelerin örnekleminde genellikle öğretmenler yer almıştır. Makalelerde en çok betimsel istatistikler ve kestirim istatistikleri yapılmış ve Maslach Tükenmişlik Envanteri kullanılmıştır. Makalelerde “kişisel başarı” kavramı 24 farklı şekilde kullanılmıştır. Maslach Tükenmişlik Envanterinin kullanıldığı bazı makalelerde ölçekten toplam puan alınmıştır. Genellikle tek değişkenli araştırmalar yapılmıştır. Tükenmişlik ile ilişkisi en çok araştırılan kavramlar “iş doyumu, olumlu örgütsel özellikler (örgütsel vatandaşlık, örgütsel bağlılık vb.), öz yeterlik/yetkinlik, olumsuz örgütsel özellikler (örgütsel sinizm, stres vb.) ve doyum/yaşam doyumu” kavramlarıdır. İncelenen ilişkisel tarama ve tarama makalelerinin büyük çoğunluğunda sonuç ve öneriler bölümleri yer almıştır. Araştırmacılar genellikle uygulamaya dönük önerilerde bulunmuşlardır ancak araştırmacılara dönük önerilere daha az yer vermişlerdir.

La presencia de los jesuitas en Colonia del Sacramento
Authors: Page Carlos A.
Published: July 2020

La permanencia de los jesuitas portugueses en Colonia del Sacramento se prolongó por poco más de medio siglo, soportando las adversidades a la que fue sometida la misma población que, con sus sistemáticas destrucciones, se pretendía borrar todo resto de memoria. De allí que en la medida de esta situación, es nuestra intención visibilizar a un grupo de hombres dedicados no solo a una amplia gama de trabajos pastorales, sino también políticos y educativos. Con todo debieron ubicarse bajo su bandera y con ello enfrentarse a sus hermanos de religión que comandaban la fuerza armada española con los habitantes de las reducciones guaraníticas. Con estos últimos aparece otro grupo de protagonistas en una historia compartida que finalmente no favoreció a nadie.

La población de la Misión de Santa Rosa de Lima (Paraguay).
Authors: Jackson Robert H.
Published: July 2020

Una consecuencia de contacto sostenido entre los europeos y los nativos americanos después de 1492 fue la introducción de enfermedades del Viejo Mundo, como la viruela y el sarampión que causaron “mortalidad catastrófica”. Este artículo documenta los patrones demográficos y los efectos de las epidemias en la población de la reducción de Santa Rosa de Lima (Paraguay), y muestra que en más de doscientos años continuos, las epidemias causaron un verdadero desastre. A pesar de la mortalidad epidémica pesada, la población de Santa Rosa se recuperó.
Los mocobíes del Chaco según la mirada del P. Manuel Canelas SJ.
Authors: Salinas María Laura , Valenzuela Fátima V.
Published: July 2020

denominado Origen de la Nación Mocobí y relato de sus usos y costumbres. Dicha fuente refleja el interés de los padres jesuitas por historizar y narrar los aspectos significativos de los pueblos indígenas, en este caso específicamente, mocobíes. Parte del documento fue utilizado y analizado anteriormente por Guillermo Furlong para su obra Entre los Mocobíes de Santa Fe (1938). En esta ocasión nos abocaremos a examinar el manuscrito y dar cuenta de la valiosa información que aporta sobre la etnia mocobí referente a su vida cotidiana, religiosa y a la cosmovisión del mundo. La fuente tiene la autoría de Manuel Canelas, un jesuita nacido en Córdoba del Tucumán cuya labor misional la realizó en la reducción de San Javier en Santa Fe durante unos diez años, circunstancia que le permitió convertirse en un investigador completo y de gran conocimiento sobre el carácter y las costumbres de esta etnia.
An Optimal Bayesian method for point analysis in discrete time

In this work we consider time series with a finite number of discrete point changes. We assume that the data in each segment follows a different probability density functions (pdf). We focus on the case where the data in all segments are modeled by Gaussian probability density functions with different means, variances and correlation lengths. We put a prior law on the change point instances (Poisson process) as well as on these different parameters(conjugate priors) and give the expression of the posterior probality distributions of these change points. The computations are done by using an appropriate Markov Chain Monte Carlo (MCMC) technique. The problem as we stated can also be considered as an unsupervised classification and/or segmentation of the time serie. This analogy gives us the possibility to propose alternative modeling and computation of change points, which are more appropriate for multivariate signals, for example in image processing.
Hand Gesture Recognition With a Novel Particle Filter
Authors: Huerta David , Crawford Eric , Brown Scott
Published: July 2020

Human Computer Interaction (HCI) has been redefined in this era. People want to interact with their devices in such a way that has physical significance in the real world, in other words, they want ergonomic input devices. In this paper, we propose a new method of interaction with computing devices having a consumer grade camera, that uses two colored markers (red and green) worn on tips of the fingers to generate desired hand gestures, and for marker detection and tracking we usedtemplate matching with kalman filter. We have implemented all the usual system commands, i.e., cursor movement, right click, left click, double click, going forward and backward, zoom in and out through different hand gestures. Our system caneasily recognize these gestures and give corresponding system commands. Our system is suitable for both desktop devices and devices where touch screen is not feasible like large screens or projected screens.

Digitization of mechatronic products and the trend towards platforms and eco-system challenges providers of mechatronic products in the development of new, digital business models and sucessful innovations. In this paper, a novel tool forstrategic planning by means of scenario-technique directly linked to a -platform is presented. An efficient tool for strategic planning is offered to the providers of mechatronic systems who want to enhance the capabilties of their products by usingservices on the plattform to achieve an added value. By linking the tool to the platform, generic influence factors and selection rules can be provided. Thereby, the required effort for strategic planning can be significantly reduced. Providersof mechatronic systems are enabled to anticipate future scenarios and to identify business opportunities in an autonomous way. The integrated tool for strategic planning is validated in a case study. The case study comprises the mechatronicproduct of a low-cost flood level warning system which uses a pan-european data platform.
WALD-EM: Wald Accumulation for Locations and Durations of Eye Movements

Published: July 2020

Describing, analyzing and explaining patterns in eye movement behavior is crucial for understanding visual perception. Further, eye movements are increasingly used in informing cognitive process models. In this article, we start by reviewing basic characteristics and desiderata for models of eye movements. Specifically, we argue that there is a need for models combining spatial and temporal aspects of eye-tracking data (i.e., fixation durations and fixation locations), that formal models derived from concrete theoretical assumptions are needed to inform our empirical research, and custom statistical models are useful for detecting specific empirical phenomena that are to be explained by said theory. In this article, we develop a conceptual model of eye movements, or specifically, fixation durations and fixation locations, and from it derive a formal statistical model --- meeting our goal of crafting a model useful in both the theoretical and empirical research cycle. We demonstrate the use of the model on an example of infant natural scene viewing, to show that the model is able to explain different features of the eye movement data, and to showcase how to identify that the model needs to be adapted if it does not agree with the data. We conclude with discussion of potential future avenues for formal eye movement models.
Decision making across adulthood during physical distancing

Covid-19-related social-distancing measures have dramatically limited physical social contact between individuals and increased monetary and health concerns for individuals of all ages. We wondered how these new societal conditions would impact the choices individuals make about monetary, health, and social rewards, and if these unprecedented conditions would have a differential impact on older individuals. We conducted two racially diverse online studies to examine temporal discounting of monetary, health, and social rewards; stated preferences for monetary, health, and social rewards; and social distancing behaviors. We used the initial study (N = 233) to test our hypotheses and we ran the second, pre-registered study (N = 243) to determine if these relationships replicated. Both studies recruited equal numbers of White/Caucasian, Black/African American, and Hispanic/Latinx participants. In both studies, we found that older adults were more likely to prefer smaller, sooner social and health-related rewards in decision-making tasks, despite the fact that there were no age differences in the stated importance of social and health rewards and no age differences in self-reported social distancing behaviors. These data further support the assertion that older adults have increased motivation for social and health rewards compared to younger individuals and that motivation is important to consider when examining decision making across the adult life span.
