Published: February 2019

Background

Previous studies in schizophrenia revealed abnormalities in the cortico-cerebellar-thalamo-cortical circuit (CCTCC) pathway, suggesting the necessity for defining thalamic subdivisions in understanding alterations of brain connectivity.

Aims

To parcellate the thalamus into several subdivisions using a data-driven method, and to evaluate the role of each subdivision in the alterations of CCTCC functional connectivity in patients with schizophrenia.

Method

There were 54 patients with schizophrenia and 42 healthy controls included in this study. First, the thalamic structural and functional connections computed, based on diffusion magnetic resonance imaging (MRI, white matter tractography) and resting-state functional MRI, were clustered to parcellate thalamus. Next, functional connectivity of each thalamus subdivision was investigated, and the alterations in thalamic functional connectivity for patients with schizophrenia were inspected.

Results

Based on the data-driven parcellation method, six thalamic subdivisions were defined. Loss of connectivity was observed between several thalamic subdivisions (superior-anterior, ventromedial and dorsolateral part of the thalamus) and the sensorimotor system, anterior cingulate cortex and cerebellum in patients with schizophrenia. A gradual pattern of dysconnectivity was observed across the thalamic subdivisions. Additionally, the altered connectivity negatively correlated with symptom scores and duration of illness in individuals with schizophrenia.

Conclusions

The findings of the study revealed a wide range of thalamic functional dysconnectivity in the CCTCC pathway, increasing our understanding of the relationship between the CCTCC pathway and symptoms associated with schizophrenia, and further indicating a potential alteration pattern in the thalamic nuclei in people with schizophrenia.

Dissecting cause from consequence: a systematic approach to thermal limits
Authors: MacMillan Heath A.
Published: February 2019

Thermal limits mark the boundaries of ectotherm performance, and are increasingly appreciated as strong correlates and possible determinants of animal distribution patterns. The mechanisms setting the thermal limits of ectothermic animals are under active study and rigorous debate as we try to reconcile new observations in the lab and field with the knowledge gained from a long history of research on thermal adaptation. Here, I provide a perspective on our divided understanding of the mechanisms setting thermal limits of ectothermic animals. I focus primarily on the fundamental differences between high and low temperatures, and how animal form and environment can place different constraints on different taxa. Together, complexity and variation in animal form drive complexity in the interactions within and among levels of biological organization, creating a formidable barrier to determining mechanistic cause and effect at thermal limits. Progress in our understanding of thermal limits will require extensive collaboration and systematic approaches that embrace this complexity and allow us to separate the causes of failure from the physiological consequences that can quickly follow. I argue that by building integrative models that explain causal links among multiple organ systems, we can more quickly arrive at a holistic understanding of the varied challenges facing animals at extreme temperatures.
Compliant legs enable lizards to maintain high running speeds on complex terrains
Authors: Druelle François , Goyens Jana , Vasilopoulou-Kampitsi Menelia , Aerts Peter
Published: February 2019

Substrate variations are likely to compel animal performance in natural environments, as running over complex terrains challenges the dynamic stability of the body differently in each step. Yet, being able to negotiate complex terrains at top speed is a strong advantage for animals that have to deal with predators and evasive prey. Only little is known on how animals negotiate such terrain variability at high speed. We investigated this in fast running Acanthodactylus boskianus lizards, by measuring their 3D kinematics using four synchronized high-speed video cameras (325Hz) on an adaptable racetrack. This racetrack was covered with four different substrates, representing increasing levels of terrain complexity. We found that the lizards deal with this complexity gradient by gradually adopting more erect parasagittal leg postures. More erected legs enable, in turn, more compliant legs use which are highly adjustable on complex terrains. Additionally, the lizards stabilise their head, which facilitates vestibular and visual perception. Together, compliant legs and head stabilisation enable the lizards to minimise movements of the body centre of mass, even when running on highly irregular terrains. This suggests that the head and the centre of mass are the priority targets for running on uneven terrains. As a result, running performance (mean forward speed) decreases only slightly, and only on the most challenging substrate under investigation.

Authors: Hernández-Vásquez Akram , Alarcon-Ruiz Christoper A. , Díaz-Seijas Deysi , Magallanes-Quevedo Luisa , Rosselli Diego
Published: February 2019

Background: Low availability of medicines in health services, self-medication, inadequate use of medicines, and inadequate dispensing practices in pharmacies are frequent problems in Peru. We aimed to evaluate how frequent the purchase of medications without medical prescription is in Peru, and which factors are associated with this practice.

Methods: We conducted a secondary analysis of the 2016 ENSUSALUD national survey data. Purchase of one or more medicines that require a prescription was measured as a dichotomous variable. Crude and adjusted prevalence ratios (PR) and their 95% confidence intervals (95% CI) were calculated using Poisson regressions model with robust variance to assess the association of purchasing of medicines that require prescriptions with sociodemographic factors.

Results: There were 3858 participants in the dataset. The prevalence of purchasing medications without prescriptions was 47.2%. History of having previously consumed the same medication (31.6%), and the delay in receiving an appointment at health facilities (26.9%) were the main reasons to buy medications without a prescription. Regarding the recommendation of the medication purchased, the advice of the pharmacy, and remembering a previous old prescription, were the most frequent reasons (38.3%, and 25.9%, respectively). On the multivariable analysis, users that buy medications without prescription were more likely to be of aged 25-44; reside in the Jungle  and Highlands regions; and self-consumption of the purchase. Individuals with Seguro Integral de Salud (Comprehensive Health Insurance) were less likely to buy medications without prescription.

Conclusions: There is a high prevalence of prescription requiring medication being bought without one from pharmacies in Peru. It is necessary to include the evaluation of consumer patterns to develop strategies with the aim to regulate the consumption of prescription drugs in the Peruvian population.

Interpreting Interactions in Linear Fixed-Effect Regression Models: When Fixed-Effect Estimates Are No Longer Within-Effects
Authors: Shaver J. Myles
Published: February 2019

Fixed-effect regression models use within-firm variation to identify coefficient estimates, which is advantageous for mitigating certain endogeneity concerns and ruling out spurious relationships. I demonstrate that fixed-effect regression models with interaction terms (and by extension quadratic or higher-degree terms) confound within-firm and between-firm variation in identifying interaction coefficient estimates. Thus, in these specifications coefficient estimates lack a desirable property of standard fixed-effect estimates. I substantiate this concern using simulations and an empirical example. I also demonstrate how segmented regression aids assessing whether within-firm or between-firm variation identifies interaction coefficient estimates in fixed-effect models.

Open Sourcing as a Profit-Maximizing Strategy for Downstream Firms
Authors: Gambardella Alfonso , von Hippel Eric
Published: February 2019

This paper characterizes and explores a corporate strategy in which downstream firms collaborate to develop open substitute designs for proprietary hardware they would otherwise purchase from upstream suppliers. This strategy centrally involves the downstream firms distributing design costs over multiple downstream firms—a strategy that is routine to producers selling to multiple downstream firms but which has been in the past typically not practical for coalitions of downstream firms. Today, downstream firms find it increasingly feasible to codesign products they may all purchase because of two technological trends. First, computer-aided design/computer-aided manufacturing and other design technologies are lowering downstream firms’ costs to develop designs for purchased hardware inputs. Second, better communication technologies are lowering the costs of doing such projects collaboratively, even among large groups of downstream customer firms. Downstream firms collaborating to develop a design for a hardware input they can all purchase could in principle choose to protect their design as a club good. However, opening up collaboratively created designs to free riders can increase the profits of the contributing firms for several reasons we explore and model. Important among these is that free revealing draws free riders away from purchases of proprietary software or hardware to customer-developed free substitutes. This “scale-stealing” mechanism reduces the markets of upstream suppliers of competing proprietary inputs. In the case of hardware only, free riders also contribute to reducing the average manufacturing costs of the open hardware by increasing purchase volumes and so creating increased economies of scale. Resulting reduced unit purchase costs benefit downstream firms contributing to the free design as well as free riders.
Políticas públicas dirigidas a la Economía Social y Solidaria. Tensiones, alcances y desafíos en la experiencia de San Martín (Argentina, 2016-2017)
Authors: García Ariel , Fontanet Fernando
Published: February 2019

Esta investigación se interroga por las formas efectivas que adquiere el asociativismo en las experiencias de economía social y solidaria (ESS) registradas en la Municipalidad de San Martín (Argentina) para el bienio 2016-2017. Desde un enfoque de triangulación metodológica, el trabajo se propone: a) analizar las tensiones entre los ideales de asociativismo propugnado desde las experiencias de ESS y las formas de proceder que se registran en los participantes de la misma; b) describir las formas de intervención estatal en las experiencias asociativas seleccionadas, considerando específicamente fuentes y modalidades de asistencia técnica (financiamiento y de capacitación). La investigación halla una marcada dependencia de los trabajadores aso-ciados a dispositivos del financiamiento estatal. Esta dependencia impide un efectivo esquema emancipatorio, aspecto que se vuelve estructural debido a la carencia de espacios alternativos y/o específicos de comercialización y de financiamiento.

Background and Aim: Fermented milk is food produced and consumed all over the world and plays an important role in human nutrition. This work aimed to evaluate the microbiological and physicochemical quality and mineral composition of fermented milk consumed in Burkina Faso.

Materials and Methods: A total of 114 samples of fermented milk from camels, goats, and cows were purchased in the market in five localities in Burkina Faso; Bobo Dioulasso, Djibo, Dori, Gorom-Gorom, and Sebba. Microbiological and physical parameters were monitored using standards methods.

Results: Microbiological analysis of fermented milks showed high average values of 7.60±1.50×109 colony-forming unit per milliliter (CFU/ml), 5.72±3.60×107 CFU/ml, 5.53±2.00×105 CFU/ml, 1.97±0.18×103 CFU/ml, 1.98±0.25×103 CFU/ ml, and 0.10±0.09×103 CFU/ml for total microbial flora, lactic acid bacteria, yeasts and molds, Staphylococcus aureus, total coliforms, and thermotolerant coliforms, respectively. None of the samples were contaminated by Salmonella or Shigella. The average values of pH, acidity, dry matter, ash, fats, proteins, and total carbohydrates content of samples were ranged, respectively: 3.830-4.137, 1.888-2.822%, 8.271-13.004%, 0.199-0.476%, 1.210-3.863%, 2.125-3.764%, and 3.080- 5.428 % (w/w). Na/K and Ca/Mg ratio ranged from 0.104 to 0.909 and from 3.392 to 16.996, respectively. Total microbial flora, yeasts and molds, total coliforms, fats, calcium, potassium, iron, and zinc were significantly different.

Conclusion: This research contributed in the evaluation of the hygienic and nutritional qualities of local fermented milk. Results obtained in this study confirm the need to set up the training program on the sanitary condition to traditional maker's to ensure the good fermented milk with high organoleptic and nutritional qualities.

Published: February 2019

Background: Population growth led to an increase in the number of people raising pigs, resulting in increased demand for piglets/pigs for breeding and pork for consumption. Aim: This study was carried out to determine the reproductive performance of pigs raised by the intensive management system in Abuja, Nigeria, with a view to assist farmers in ensuring improved productivity and profitability. Materials and Methods: Using an interview-based questionnaire, data from 121 sows and 649 preweaning piglets were collected in 12 herds, from September 2017 to March 2018. Measures of reproductive and production performance assessed in this study were interfarrowing interval (IFI), number of liveborn piglets (NLB), preweaning piglet mortality (PPM), age at weaning (AAW), weaning to service interval (WSI), age at first farrowing (AFF), number of piglets weaned per litter (NPWL), and number of piglets weaned per sow per year (NPWPY). Results: The results obtained in this study were IFI 6.2±0.84 months, NLB 7.2±1.11, PPM 31%, AAW 40.2±3.12 days, NPWL 5.3±0.73, WSI 39.4±4.59 days, AFF 9.1±0.60 months, and NPWPY 8.1±1.21. The identified causes of PPM were maternal overlay 31.34%, splay leg/hypoglycemia 22.39%, cannibalism 20.40%, starvation 14.93%, and unknown cause 10.94%. Conclusion: The result showed that the reproductive performance of the sow (especially, NPWPY and PPM) needs to be improved on. There is a need to promote extension and herd health services by veterinarians and livestock personnel to potential and existing farmers in the area. This is more so because organized pig production in the studied area is relatively new and more people are establishing pig farms in the studied area.
“The Protestant Contention”: Religious Freedom, Respectability Politics, and W. A. Criswell in 1960
Authors: Miller Eric C. , Towns James E.
Published: February 2019

Though rhetorical critics have been very attentive to John F. Kennedy’s rhetoric during the 1960 campaign, less attention has been paid to that of his conservative Protestant antagonists. To address the omission, this essay considers W. A. Criswell’s July 3, 1960 address, “George Truett and Religious Liberty,” portions of which were reprinted and widely distributed as a pamphlet titled Religious Freedom, the Church, the State, and Senator Kennedy. These texts, we argue, are exemplary of a larger Protestant strategy during the 1960 race. Because Kennedy’s candidacy had prompted fierce vitriol from the anti-Catholic Right, conservative Protestant leaders from across the denominational spectrum tempered their attacks so as not to alienate centrist voters. Their measured adoption of religious freedom arguments allowed them to occupy the respectable middle, assailing Kennedy’s Catholicism while parrying charges of religious bigotry. In Criswell’s rhetoric, we find a pure distillation of this strategy, identifying it as a species of respectability politics with enduring appeal—this time from the Right.
Finnish social services students’ perceptions of purpose and helping unknown others
Authors: Manninen Niina , Kuusisto Elina , Tirri Kirsi
Published: February 2019

This mixed methods study introduces the concept of purpose in the social pedagogical education of Finnish social services students (N = 151). The aim of this study is to specify the purpose profiles of the students and to investigate how students with different profiles define the intended outcome of having a purpose in life and why they want to help unknown others. Three purpose profiles are identified: dabbler, purposeful and dreamer. Most of the social services students appear to be dabblers, who differ from the purposeful group in that they keep searching for new purposes in life. Purposeful students were the most able to address values as their guiding principles in life, although what was most important for students in all profiles was to pursue a pleasant life rather than a value-driven or some form of good life. Purposeful students also specified value-based helping goals more than others and felt that their own well-being was the key to helping others. The study points out that students’ awareness of their values and purposes should be promoted during their social pedagogical education. Most students might not be aware why they are pursuing a helping profession. Students could be supported in identifying helping unknown others as their life purpose in order to promote their wellbeing, satisfaction at work and wider understanding of the personal level and social level impacts of helping.

The effect of pecking order, trade-off and market timing theories on capital structure in commercial banking companies listed on IDX
Authors: Africa Laely Aghe , Sunani Avi
Published: February 2019

Capital structure has an impact on the short and long term. Funding provided by banks is inseparable from the availability of funds from third parties in the form of savings, demand deposits and deposits. The entry of third party funds must be balanced with the funds disbursed by the company. Therefore, management policy greatly determines the position and composition of funding. This study aims to analyze and determine several capital structure theories, namely Pecking Order Theory, Trade-Off Theory and Market Timing Theory. The variable of Pecking Order Theory is represented by funding deficit, long-term debt, and total debt. The variable of Trade-Off Theory is represented by tangi-ble assets, growth, size, profitability, total debt, and long-term debt. The variable of Mar-ket Timing Theory is represented by Equity Finance Weighted Average of market to book ratio and leverage ratio. This research is quantitative research. The samples used in this study are 100 data of commercial banking companies listed on IDX period 2011 - 2015. Data are obtained using purposive sampling method from banks registered at www.idx.go.id. Multiple Liner Regression is used in analyzing data using SPSS IBM 23. The results of the research show that Trade-Off and Market Timing Theories can be implemented by banking companies in terms of determining capital structure. This re-search implication is to enhance management choices, especially on how to set capital structure of the company.

Belief-adjustment model (information order and disclosure pattern) and fram-ing effect are pretended in some factors, which influence investors to make different deci-sions. Design of experiment for this research is 2Ã—2Ã—2. Participants involved in this research are 111 undergraduate students of STIE Perbanas Surabaya majoring in Ac-counting and Management. The statistical method used in this study is independent sample t-test or mann-whitney u-test. The results show that either step-by-step or end-of-sequence presentation patterns can cause recency effect, and it is greater for sequential condition than simultaneous condition. But, the result is inconsistent for end-of-sequence pattern which in some conditions can caused no order effect. In another side, the result also proves that framing effect can influence investorâ€™s consideration in deci-sion making.

Reinforced concrete is commonly used in any infrastructures. In building, it can be applied for beam and column separately, but the joints between those elements in this type of structure might be vulnerable due to the strength compared to the element itselft. In this study, some parameters namely ductility, stiffness, and energy dissipation of beam-column connection in precast concrete will be examined using finite element method. Six samples in this experiment are made considering some variations such as connection type in interior and exterios condition, round-shaped and rectanguler-shaped of column, and T-shaped and rectanguler-shaped of beam. Static loads were given in the middle of the beam and column so that the crack pattern can be obtained. From this experiment, it will be known the best and suitable joints by observing those three parmeters.

Asphalt polymer has superior characteristics than conventional asphalt. Styrene Butadiene Styrene (SBS) is a polymer that has proven its performance in heavy traffic, but it must be imported and expensive. Crumb rubber have high potential to be used as an asphalt modifier. Asphalt modified crumb rubber has high viscosity and is not homogeneous, so that the utilization cannot be delayed. This reduces workability in the field. This study aims to obtain asphalt modified crumb rubber which is easier to use by adding materials that do not affect its performance. RejIRE is a low viscosity additive to restore the properties of bitumen on crumb rubber modified. Experiments were carried out by adding variations in RejIRE levels to crumb rubber modified asphalt to determine its characteristics. Continued investigation of the performance of hot paved mixtures for wearing courses compared to asphalt mixtures with Pen 60/70 asphalt and SBS modified asphalt mixtures. The result is the addition of 0.75% RejIRE on asphalt crumb rubber modification have high workability. Overall the performance of the mix with SBS modified asphalt is better, but the mixture of hot paved with modified asphalt crumb rubber has a resistance to permanent deformation superior to the other paved mixtures.

A solvent extraction of 6- gingerol from fresh ginger rhizome chips using n-hexane has been successfully carried out. This study aimed to investigate the effects of temperature, feed size, and feed mass on the yield of gingerol, to observe the kinetics of gingerol extraction process using n-hexane as a solvent, to find the most influential parameters in the gingerol extraction process and to determine the optimum conditions of the gingerol extraction process. The experiment was carried out for 60 minutes using two feed mass ( 50 and 75 g), two temperature (60 and 70 oC) and two chips sizes (100 and 25 mm3) using 350 mL n-hexane. The second-order kinetics model was used to study the extraction kinetic parameters. The quick method was used to evaluate the most influential extraction parameters with respect to the yield of gingerol. Feed mass was found to be the most influential parameter in the gingerol extraction process. The optimum extraction conditions were found to be at 60 °C, ginger rhizome chips with 25 mm size3, feed mass was 109.7g and 350 mL n-hexane, which resulted in crude extract with gingerol content of 517.11 ppm.

Graphite felt (GF) with numerous merits has been widely used as electrode in all-vanadium redox flow batteries (VRFB), but its further application is still hindered by its intrinsically poor electrocatalytic activity. Herein, we propose a three-dimensional (3D) conducting network constructed with reduced graphene oxide (rGO) in the GF electrode via a two-step method. The 3D conducting network with abundant oxygen-containing functional groups in the GF is conducive to the transport of electrons between GF fibers and the electrochemical charge transfer to vanadium ions in the composite electrode; it can enhance the electrocatalytic activity and conductivity of GF. The VRFB using 3D rGO modified GF (mGF) electrode exhibited outstanding energy efficiency of 73.4% at a current density of 100 mA·cm−2, which is much higher than that with pristine GF (pGF) (65.4%); and better rate capability. These first results reveal that GF with 3D conducting network shows promising opportunities for the VRFB and other electrochemical flow systems
The interactional making of a “true transsexual”: Language and (dis)identification in trans-specific healthcare
Authors: Borba Rodrigo
Published: February 2019

Can the transsexual subject speak in their own terms? This is the question this article addresses. Grounded on a Foucauldian genealogical approach to discourse analysis and on Goffmanian-inspired interactional analysis, it investigates how knowledge systems that pathologise transsexuality as a mental disorder get gradually embodied (and spoken) in consultations at a Brazilian gender identity clinic. The analysis follows the interactional history a trans woman had with the clinic’s psychologist and traces the intertextual links that connect various consultations in time. This series of encounters constitutes a socialisation trajectory during which the trans client is led to speak a language that is not hers in order to frame an identity performance within the diagnostic criteria for the identification of “true transsexuals”. The article, thus, contributes to three areas for the study of transgender and language: (1) it investigates how transsexual people are led to speak a language that is not their own (the problems of agency and trans-autonomy); (2) it points to the centrality of studying how others speak to transsexual people – a gap identified by Don Kulick but which remains under-investigated; and (3) it highlights the importance of language use for the design of trans-positive and trans-affirmative healthcare practices.
