DEVELOPMENT AND TESTING OF ARROWROOT (MARANTHA ARUNDINACEA L.) GRINDING MACHINE
Authors: Pascua Alexander
Published: April 2020

An arrowroot grinding machine was developed and evaluated in terms of functional performance and cost effectiveness. The model consists of different component assembly parts such as transmission, rasper, crusher and base frame. It is powered by a 7.5 hp gasoline engine. Its salient features such as: 1) made of locally available food grade materials, 2) portable and 3) can be operated by a single person, give it the edge over other existing machines in attaining effective processing. The model has an overall cost of P65,000.00. The effects of different factors which include the machine speed, tuber size and tuber maturity on the response variables such as power requirement, processing time, machine capacity and efficiency (percent starch recovery) were observed. RSReg and Response Surface Methodology (RSM) were used to determine the effect of the treatment factors and optimum performance of the machine; respectively. Experimental runs using Box and Behnken design with three levelincomplete factorial designs were conducted. Results revealed that change on the levels of treatment factors significantly affect most of the response variables. Data obtained from the response variables mostly fit the linear and quadratic regression models. Results of evaluation revealed that the model is capable of grinding arrowroot tubers with average power consumption of 0.85 kW, processing time of 7.85 minutes, capacity of 46.6 kilograms per hour and efficiency (starch recovery) of 16.6%. Verification tests indicated that the actual values of responses were relatively close to the predicted values. Further, financial analysis showed that the machine was economically feasible for small scale farm arrowroot production with payback period of 0.343 years or 4 months and 3 days, break-even point of around 350 kg per year and benefit cost ratio of 1.96.

Published: April 2020

Staff training and development strategies are considered a ‘sine qua non’ for a sustainable leadership succession in any organisation. This descriptive survey research design sought to ascertain the level of implementation of training strategies for leadership succession in small and medium scale construction companies in the study area. A questionnaire with 5-point rating scale was employed to elicit responses from 93 CEOs on staff training and development strategies including policies and procedure, opportunities, funding, and incentives and rewards for training. A hypothesis was formulated, and tested with t-Test, to determine any difference in the responses between the small and the medium scale companies under study. Results indicated that even though the respondents practiced some of the strategies without funding in the mean, they are generally indifferent to leadership succession through staff training. There was no significant difference in the mean responses of the small and the medium scale construction companies. It was recommended that the construction companies be more committed to effective leadership succession by organising and funding training workshops and seminars for staff.

Una aproximación a la distribución de la producción laminar en Patagonia meridional
Authors: Pallo Cecilia , Cirigliano Natalia Andrea , Charlin Judith , Borrazzo Karen
Published: April 2020

Se presenta una primera aproximación a la distribución de la producción laminar manufacturada en lutita al sur de la sierra Baguales (Patagonia sur continental, entre Argentina y Chile). Si bien las láminas son características del área noroccidental al núcleo poblacional identificado en el campo volcánico Pali Aike (Última Esperanza en Chile, y la zona circundante a sierra Baguales en Argentina, La Verdadera Argentina, y sectores más al sur de la misma -Eas. Santa Ana, Cancha Carrera-), también se registran en menor frecuencia hacia el área sureste, que incluye el campo volcánico Pali Aike y los espacios próximos a él. Los resultados indican que varias fuentes potenciales de lutita permiten explicar la distribución de instrumentos laminares en el área noroccidental. En el área suroriental, la presencia de instrumentos laminares podría ser producto de mecanismos de circulación humana y de bienes a escala amplia, o bien del uso de otras materias primas de fuentes de aprovisionamiento cercanas aún no identificadas.
El uso del cuarzo en la Sierra El Alto-Ancasti (Catamarca, Argentina). Experimentación y casos arqueológicos
Authors: Egea Debora , Gerola Ignacio
Published: April 2020

Los estudios de la tecnología lítica de las ocupaciones de la segunda mitad del primer milenio de la era en la Sierra de El Alto-Ancasti nos han permitido pensar en una producción caracterizada por una manufactura simple, de bajo grado de formatización de los instrumentos, donde destaca el aprovechamiento del cuarzo como materia prima. El cuarzo presenta características intrínsecas propias de su composición que dificultan la identificación de rasgos antrópicos diagnósticos que nos otorguen información sobre las historias de producción y las diferentes estrategias implementadas por los talladores a la hora de confeccionar su instrumental. Debido a esto se emprendió un abordaje experimental orientado a someter a prueba hipótesis explicativas sobre el comportamiento de esta materia prima ante diferentes técnicas de talla. Pretendemos probar la potencialidad de la experimentación para inferir comportamientos que no pueden ser observados directamente con los análisis descriptivos que venimos realizando en los conjuntos líticos de la zona.
Procesos de formación de conjuntos líticos: casos de estudio y abordajes metodológicos
Authors: Carranza Eugenia , Balirán Catalina , Bobillo Federico , Sitzia Luca
Published: April 2020

El registro arqueológico lítico de superficie se encuentra expuesto a diversos agentes postdepositacionales, que desencadenan una serie de modificaciones que son parte de los procesos de formación de los conjuntos que hallamos. El estudio de estas modificaciones brinda información indispensable a la hora de proponer interpretaciones conductuales sobre los grupos humanos del pasado. En este trabajo se destaca la relevancia que tiene la aplicación de un programa tafonómico al estudio de conjuntos líticos superficiales. Para ello, se consideraron los avances realizados en tres casos de estudio en zonas desérticas/semidesérticas de Argentina. Entre las metodologías utilizadas en cada caso se encuentran observaciones naturalistas, muestreos, experimentaciones y estudios a escala del artefacto, por ejemplo, análisis de la abrasión eólica. A partir de las problemáticas analizadas en cada caso se pudo reconocer el rol de la erosión eólica y/o circulación de aguas superficiales, o el pisoteo animal, como agentes de transformación que inciden en la estabilidad de los conjuntos líticos superficiales y en sus atributos cuantitativos y cualitativos. El armado de un programa tafonómico permite analizar los efectos generados por los procesos postdepositacionales y conocer la naturaleza preservada o transformada de los contextos líticos con los cuales se trabaja.
Experimentos y esquemas diacríticos para explorar técnicas de talla unifacial del Holoceno temprano en el noroeste de Santa Cruz
Authors: Civalero Maria Teresa , Nami Hugo G.
Published: April 2020

En el registro arqueológico del Holoceno temprano del noroeste de la provincia de Santa Cruz se identificó una modalidad peculiar de manufactura de instrumentos líticos unifaciales. En su secuencia de reducción las formas-bases se preformaron con lascados unifaciales-parcial o totalmente extendidos- y se las finalizaba con retoques escamosos cuya profundidad normalmente no excede los ~10 mm. Con el propósito de profundizar en el conocimiento de su manufactura se efectuaron experimentos replicativos y análisis diacríticos de los especímenes experimentales y arqueológicos. Los resultados obtenidos muestran que los lascados total o parcialmente extendidos corresponden a una acción preconcebida y deliberada tendiente a la formatización del soporte y no son accidentales ni resultan de las reactivaciones. Así, se refuerza la posición de que esta manera de confeccionar utensilios correspondería a un estilo técnico compartido por las ocupaciones del Holoceno temprano en la Patagonia centro-meridional.

Análisis de explotación del volumen de las rocas
Authors: Santos Valero Florencia , Barros Paula
Published: April 2020

El presente Simposio fue planteado con el objetivo de conocer diferentes formas de abordar el estudio de aquellos criterios técnicos que incidieron en la explotación volumétrica de las rocas por parte de las sociedades cazadoras-recolectoras del pasado. Esto incluye diferentes momentos de la cadena operativa, desde la búsqueda de determinadas morfologías de nódulos en las fuentes, los criterios técnicos utilizados para la preparación y explotación de los núcleos, la identificación de los objetivos de producción, su confección y el mantenimiento de los instrumentos. En este sentido, la invitación a participar apuntó a trabajos que excediesen los análisis que se realizan en las canteras-taller, abordando esta problemática incluso desde en las etapas finales de elaboración de instrumentos y en sitios distantes a cientos de kilómetros de las fuentes. Los casos de estudio presentados excedieron con creces las expectativas originales del Simposio, permitiendo conocer cómo se trabaja esta temática en sitios con rangos temporales del Pleistoceno-Holoceno, Holoceno medio y tardío. Particularmente en el presente volumen se exponen algunos de estos trabajos, donde se podrán leer los resultados de investigaciones desarrolladas en contextos muy diversos: un alero localizado en las sierras de Tandilia, un sitio a cielo abierto en el área Interserrrana, campamentos residenciales en el sur de la provincia de Buenos Aires, ocupaciones en cuencas lacustres del centro-oeste de Santa Cruz y sitios tempranos en la región de Serranápolis en Brasil.

Although definitions of emotion dysregulation infer difficulties in selecting and implementing emotion regulation (ER) strategies, surprisingly few studies have examined the relationship between trait emotion dysregulation and a wide range of specific ER strategies. The present study used a data-driven approach to assess trait- and state-related ER strategy use in 99 women (aged 18-55) recruited from the community with varying levels of trait emotion dysregulation. Participants completed self-report questionnaires assessing habitual ER strategy implementation and self-ratings of ER strategy use in vivo during negative mood inductions. Principal components analysis revealed four self-report questionnaire-based and three mood-induction-based groupings comprising both optimal and suboptimal strategies. After adjusting for demographic and clinical variables, results from self-report questionnaires indicated that trait emotion dysregulation was significantly associated with higher endorsements of suboptimal strategies in two groupings (e.g., self-criticism, rumination, and social withdrawal; catastrophizing and blaming others) and lower endorsements of optimal ER strategies in one grouping (e.g., cognitive reappraisal and problem solving). In the context of mood induction, trait emotion dysregulation was significantly associated with higher endorsements of suboptimal ER strategies from one cluster only (e.g., expressive suppression, thought avoidance, and self-criticism). Such transdiagnostic, data-driven approaches can uncover how the application of specific ER strategies both habitually and during negative mood states is associated with trait emotion dysregulation.
No Evidence for an Object Working Memory Capacity Benefit with Extended Viewing Time

Visual working memory is the ability to hold visual information temporarily in mind. A key feature of working memory is its starkly limited capacity, such that only a few simple items can be remembered at once. Prior work has shown that this capacity limit cannot be circumvented by providing additional encoding time — whether providing just 200 ms or up to 1,300 ms, capacity is still limited to only 3-4 items. In contrast, Brady, Störmer, and Alvarez (2016) hypothesized that real-world objects, but not simple items used in prior research, benefit from additional encoding time and are not subject to traditional capacity limits. They supported this hypothesis with results from both behavior and the contralateral delay activity (CDA), an EEG marker of working memory storage, and concluded that familiar, complex stimuli are necessary in order to observe encoding time effects. Here, we conducted three replications of Brady et al.’s key manipulation with a larger number of participants and more trials per condition. We failed to replicate their primary behavioral result (objects benefit more than colors from additional encoding time) and failed to observe an object-specific increase in the CDA. Instead, we found that encoding time benefitted both simple color items and real-world objects, in contrast to both the findings by Brady et al. and some prior work on this topic. Overall, we observed no support for the hypothesis that real-world objects have a different capacity than colored squares. We discuss the implications of our findings for theories of visual working memory.
From Aristocratic to Ordinary: Shifting Modes of Elite Distinction
Authors: Reeves Aaron , Friedman Sam
Published: April 2020

How do elites signal their superior social position via the consumption of culture? We address this question by drawing on 120 years of “recreations” data (N = 71,393) contained within Who’s Who, a unique catalogue of the British elite. Our results reveal three historical phases of elite cultural distinction: first, a mode of aristocratic practice forged around the leisure possibilities afforded by landed estates, which waned significantly in the late-nineteenth century; second, a highbrow mode dominated by the fine arts, which increased sharply in the early-twentieth century before gently receding in the most recent birth cohorts; and, third, a contemporary mode characterized by the blending of highbrow pursuits with everyday forms of cultural participation, such as spending time with family, friends, and pets. These shifts reveal changes not only in the contents of elite culture but also in the nature of elite distinction, in particular, (1) how the applicability of emulation and (mis)recognition theories has changed over time, and (2) the emergence of a contemporary mode that publicly emphasizes everyday cultural practice (to accentuate ordinariness, authenticity, and cultural connection) while retaining many tastes that continue to be (mis)recognized as legitimate.
More similarities than differences between ADHD and ASD in functional brain connectivity

Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are highly comorbid neurodevelopmental conditions. There is an ongoing debate regarding the nature of their overlap. Behavioral symptoms and cognitive profiles indicate differences between the conditions, but genetic studies and neuroimaging investigations suggest at least some shared etiology. The current study investigated if functional connectivity can be used to distinguish ADHD and ASD using a machine-learning approach. Towards this aim, we trained a machine learning algorithm to distinguish ASD and ADHD cases from each other and from comparison cases in a total sample of 805 cases, comprising of 243 ASD cases, 164 ADHD cases, and 398 comparison cases between 7 and 21 years of age. We compared the performance of the best performing machine learning algorithm (l2-regularised support vector classification) when classifying unseen cases of ADHD, ASD, and CMP. The results indicated lower classification performance when distinguishing ADHD from ASD compared to classifying diagnostic groups vs a typical comparison group. The model trained to distinguish ASD and comparison cases performed equally well when tasked with classifying ADHD vs CMP. A Bayesian analysis gave strong evidence for similarity ADHD and ASD. The ADHD and ASD group showed overlap in connections of the right ventral attention network, the salience network, and the default mode network. In sum, these results suggest a substantial overlap in functional brain connectivity between ADHD and ASD. We discuss the implications of these findings for the quest to identify functional neuroimaging biomarkers and provide recommendation for future research.

Introduction and Aims: The ability to accurately detect alcohol or other drug intoxication is an important skill for people who use these substances and for a variety of professions (e.g., policing, responsible service of alcohol). Previous studies have found that intoxicated people are generally poor at estimating their own level of intoxication (particularly at high Blood Alcohol Concentration; BACs) and the link between intoxication and BAC appears to drop-off at higher BAC levels. But studies of observer ratings of other’s intoxication have yielded mixed results. The aim of this study was to investigate both self- and observer-ratings of intoxication against BAC levels to determine whether we see a similar drop-off in intoxication report for both self- and observer-rated intoxication.Design and Methods: Participants were 388 students interviewed outside three university events. Participants provided demographics, a rating of how intoxicated they felt (0=not at all, 10=very), and provided a breath test. Interviewers recorded a rating of how intoxicated the participant appeared to be.Results: We fitted our data with both polynomial and linear regressions. Polynomial regression provided a better fit when predicting both self-rated intoxication (r2=0.49 vs. r2=0.40, p < 0.001) and observer-rated intoxication from BAC (r2 = 0.58 vs. r2 = 0.52, p < 0.001), suggesting that there is a drop-off for both intoxication ratings.Discussion and Conclusions: Both self-rated and observer-rated intoxication appeared to drop-off at higher levels of BAC. This may be due to either tolerance or a ‘ceiling effect’ for observable signs of intoxication.
Early Executive Functions Questionnaire

Published: April 2020

Executive functions (EFs) enable us to control our attention and behavior in order to set and work toward goals. Strong EF skills are linked to better academic performance, and greater health, wealth, and happiness in later life. Research into EF development has been hampered by a lack of scalable measures suitable for infancy through to toddlerhood. The 31-item Early Executive Functions Questionnaire (EEFQ) complements temperament measures by targeting cognitive and regulatory capabilities. Exploratory Factor Analysis (n = 486 8- to 30-month-olds) and Confirmatory Factor Analysis (n = 317 9- to 30-month-olds) indicate Inhibitory Control, Flexibility, and Working Memory items load onto a common “Cognitive Executive Function (CEF)” factor, while Regulation items do not. The CEF factor shows strong factorial measurement invariance for sex, and partial strong factorial measurement invariance for age. CEF and Regulation scores show limited floor and ceiling effects, good internal consistency, short-term stability, and convergent validity with carer-report measures of attentional control. The EEFQ is sensitive to developmental change. Results indicate that the widely overlooked period between late infancy and early toddlerhood may be a sensitive period for EF development. The low-resource demands of the EEFQ afford the possibility to study emergent EFs at scale; opening up new opportunities in basic developmental and intervention research.

The use of structured risk assessment instruments (SRAIs) has increased significantly over the past decades, with research documenting variation between countries. The use of SRAIs, their perceived utility and potential for mitigating bias in forensic risk evaluations (FREs) was investigated in a survey of Dutch forensic mental health practitioners (N = 110) We found generally positive views regarding SRAI utility. Bias in FREs was of concern to respondents. We found no evidence of a bias blind spot (the belief that oneself is less prone to bias than peers/colleagues). SRAIs were rated as the most effective debiasing strategy, but respondents also endorsed introspection. There were few differences in beliefs about sources of bias or debiasing strategies between respondents who had bias training and those who had not, suggesting the need for development of effective strategies to mitigate bias and training related to bias in FREs.
Volumetric and connectivity changes in brain networks associated with reward sensitivity, cognitive control, and negative affect in binge eating disorder and bulimia nervosa

Bulimia nervosa (BN) and binge eating disorder (BED) are characterized by episodes of eating large amounts of food whilst experiencing a loss of control. Recent studies suggest that the underlying causes of BN/BED consist of a complex system of environmental cues, atypical processing of food stimuli, altered behavioral responding, and structural/functional brain differences compared with healthy controls (HC). In this narrative review, we provide an integrative account of the brain networks associated with the three constructs most integral to BN and BED, namely increased reward sensitivity, decreased cognitive control, and altered negative affect and stress responding. We show altered activity in BED/BN within these networks, specifically in the striatum, insula, prefrontal and orbitofrontal cortex, and cingulate gyrus. Numerous key nodes in these networks also differ in volume and connectivity compared with HC. We provide suggestions for how this integration may guide future research into these brain networks and constructs.
