Incentives for Prosocial Behavior: The Role of Reputations
Authors: Exley Christine 
Published: March 2017

Do monetary incentives encourage volunteering? Or, do they introduce concerns about appearing greedy and crowd out the motivation to volunteer? Since the importance of such image concerns is normally unobserved, the answer is theoretically unclear, and corresponding empirical evidence is mixed. To help counter this ambiguity, this paper proposes that the importance of image concerns—such as the desire to appear prosocial and not to appear greedy—relates to individuals’ volunteer reputations. Experimental results support this possibility. Individuals with past histories of volunteering are less responsive to image concerns if their histories are public, or if their prosocial tendencies are already known. Consistent with a decreased importance of appearing prosocial, they are less likely to volunteer. Consistent with a decreased importance of not appearing greedy, they are less likely to be discouraged by public incentives.Data are available at https://doi.org/10.1287/mnsc.2016.2685 .This paper was accepted by Uri Gneezy, behavioral economics.

Abstract. Karyati, Ipor IB, Jusoh I, Wasli ME. 2017. The diameter increment of selected tree species in a secondary tropical forest in Sarawak, Malaysia. Biodiversitas 18: 304-311. The diameter at breast height (DBH) increments of dominant tree species in a secondary forest can determine forest growth in the area. This study was conducted to investigate the DBH increments of the nine dominant tree species in a secondary tropical forest. A total number of 180 trees representing nine species, seven genera, and six families were selected for the assessment of DBH increments during two years of study. Those nine species, namely: Acacia mangium Willd. (2.33 cm year-1), Endospermum diadenum (Miq.) Airy Shaw (1.05 cm year-1), Cratoxylum arborescens Blume. (0.96 cm year-1), Vernonia arborea Buch. Ham. (0.96 cm year-1), and Cratoxylum glaucum Korth. (0.80 cm year-1) had shown a high growth rate during the assessment, while the other four species such as Macaranga gigantea Mull. Arg., Macaranga triloba Mull. Arg., Euodia glabra (Bl.) Bl., and Vitex pubescens Vahl. had 0.53, 0.48, 0.37, and 0.30 cm year-1 in DBH increments, respectively. The average DBH increments for the entire selected species was 0.86 cm year-1 for periodic measurement and 0.75 cm year-1 for monthly measurement. This information is needed in order to understand the succession process in the secondary forests. It is important for the selection of the suitable species in a reforestation and a rehabilitation projects.

Abstract. Kothandaraman S, Sundarapandian S.2017. Structure of plant community in tropical deciduous forests of Kanyakumari Wildlife Sanctuary, India. Biodiversitas 18: 391-400. Plantcommunity structure of two tropical deciduous forest sites (I and II which are in different locations with different terrain characteristics viz., elevation and slope pattern) in Kanyakumari Wildlife Sanctuary, Western Ghats were assessed using standard phytosociological methods. Ten plots of 20 m x 20 m each were laid for woody species enumeration and 40 quadrats of 1 m x 1 m (4 in each plot) for understorey vegetation (herbs and plant species that are < 1 m in height) in each site. Overall, 76 plant species were recorded from 41 families, of which 23 contribute to understory. Site I (62) was twice as speciose as site II (31). Greater diversity index of adult woody vegetation was observed in site I (2.30) than site II (2.01). The woody individuals (diameter at breast height, DBH â‰¥ 10 cm) were more abundant in site I (518 individuals ha-1) than site II (448 individuals ha-1). The basal area of adult trees in sites I and II are 34.7 m2 ha-1 and 30.8 m2 ha-1 respectively. Euphorbiaceae was the most speciose family in both the sites. Twenty-five families in site I and seventeen families in site II were represented by singletons. Diameter class-wise distribution of adult trees showed a typical â€˜reverse J-shapedâ€™ curve indicating good regeneration status. Concerning understory, site I (19 species) has a greater diversity than site II (six species). The observed differences in the vegetation patterns between the two deciduous forest sites are possibly due to variations in elevation, terrain features and edaphic characteristics.

Hartati S, Nandariyah, Yunus A, Djoar DW. 2017. Cytological studies on black orchid hybrid (Coelogyne pandurata Lindley). Biodiversitas 18: 555-559. Black orchid (Coelogyne pandurata Lindley) is one of the rare species of Coelogyne Lindley, protected by the government of Indonesia. The cytological character of orchid is very important to study to support the success of breeding. The study aimed to assess the chromosomal number, karyotype pattern and ploidy level the hybrid of Black Orchid (Coelogyne pandurata). This study shows that the chromosomal number of the hybrid of Coelogyne pandurata (2n = 36) >< Coelogyne rumphii (2n = 72) is 2n = 54. Ploidy analysis by flow cytometry shows that hybrid shows triploid (2n = 3x = 54) different from the parent Coelogyne pandurata which is diploid (2n = 2x = 36) and the parent Coelogyne rumphii which is tetraploid (2n = 4x = 72). However, both parents and their hybrid performed the same karyotype pattern, which is metacentric. The chromosome size showed a variation in length from the longest Coelogyne pandurata 2.98 Â± 0.15 Âµm to the shortest Coelogyne rumphii 2.24 Â± 0.15 Âµm. The hybrids have a range of 2.50 Â± 0,10 Âµm to 2.85 Â± 0.10 Âµm. Karyotype patterns of black orchid (C. pandurata), C. rumphii and the hybridis metacentric.
Fundamental hemodynamic mechanisms mediating the response to myocardial ischemia in conscious paraplegic mice: cardiac output versus peripheral resistance
Authors: Lujan Heidi L. , DiCarlo Stephen E. 
Published: March 2017

AbstractAutonomic dysfunction, a relative sedentary lifestyle, a reduced muscle mass and increased adiposity leads to metabolic abnormalities that accelerate the development of coronary artery disease (CAD) in individuals living with spinal cord injury (SCI). An untoward cardiac incident is related to the degree of CAD, suggesting that the occurrence of a significant cardiac event is significantly higher for individuals with SCI. Thus, understanding the fundamental hemodynamic mechanisms mediating the response to myocardial ischemia has the potential to positively impact individuals and families living with SCI. Accordingly, we systematically investigated if thoracic level 5 spinal cord transection (T5X; paraplegia) alters the arterial blood pressure response to coronary artery occlusion and if the different arterial blood pressure responses to coronary artery occlusion between intact and paraplegic mice are mediated by changes in cardiac output and or systemic peripheral resistance and whether differences in cardiac output are caused by changes in heart rate and or stroke volume. To achieve this goal, the tolerance to 3 min of coronary artery occlusion was determined in conscious intact and paraplegic mice. Paraplegic mice had an impaired ability to maintain arterial blood pressure during coronary artery occlusion as arterial pressure fell to near lethal levels by 1.38 ± 0.64 min. The lower arterial pressure was mediated by a lower cardiac output as systemic peripheral resistance was elevated in paraplegic mice. The lower cardiac output was mediated by a reduced heart rate and stroke volume. These results indicate that in paraplegic mice, the arterial pressure response to coronary artery occlusion is hemodynamically mediated primarily by cardiac output which is determined by heart rate and stroke volume.

Authors: Lafta Sadeq H. 
Published: March 2017

AbstractNano nickel ferrite particles were prepared at pH values 1.5, 4, 7, 10, 13 by a hydrothermal method using metal chlorides and NaOH as an oxidant and solution basicity controller. There is a phase transition from hematite to spinel ferrite that begins when the pH reaches 4. The lowest crystallite size (4 nm) was associated with a highest lattice constant (8.345 Å), at pH=4. Whereas maximum crystallite size 64.5 nm corresponds lattice constant of 8.298 Å at pH=10. The highest magnetization (48 emu/g) value was achieved for the sample prepared at pH=7, which at the same time has a lower coercivity. The samples synthesized at pH ≥4 show superparamagnetic behavior owing to its low particle size and to zero field cooling and field cooling measurements. The ferromagnetic resonance (FMR) cavity tests analysis show that the broadened linewidth (770 Oe) and high imaginary permeability or high microwave absorption which is linked to high magnetization and low coercivity of superparamagnetic particles and their aggregation. There was a shift in the resonance field due to internal fields and cation distribution.
Does Macaulay Duration Provide The Most Cost-Effective Immunization Method – A Theoretical Approach
Authors: Zaremba Leszek 
Published: March 2017

Abstract
In the following, we offer a theoretical approach that attempts to explain (Comments 1-3) why and when the Macaulay duration concept happens to be a good approximation of a bond’s price sensitivity. We are concerned with the basic immunization problem with a single liability to be discharged at a future time q. Our idea is to divide the class K of all shifts a(t) of a term structure of interest rates s(t) into many classes and then to find a sufficient and necessary condition a given bond portfolio, dependent on a class of shifts, must satisfy to secure immunization at time q against all shifts a(t) from that class. For this purpose, we introduce the notions of dedicated duration and dedicated convexity. For each class of shifts, we show how to choose from a bond market under consideration a portfolio with maximal dedicated convexity among all immunizing portfolios. We demonstrate that the portfolio yields the maximal unanticipated rate of return and appears to be uniquely determined as a barbell strategy (portfolio) built up with 2 zero-coupon bearing bonds with maximal and respective minimal dedicated durations. Finally, an open problem addressed to researchers performing empirical studies is formulated.

AbstractCoexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients.A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia. Taking into consideration good blood supply to the axillary artery via reversed blood flow in the thyreocervical trunk, hence we decided not to proceed with cervicoaxillary bypass grafting.Implantation stent-graft into aorta coarctation with covering axillary artery is proper way of treatment and may need no other surgical procedures.

Abstract
Chapman, M, Larumbe-Zabala, E, Gosss-Sampson, M, Colpus, M, Triplett, NT, and Naclerio, F. Perceptual, mechanical, and electromyographic responses to different relative loads in the parallel squat. J Strength Cond Res 33(1): 8–16, 2019—The effectiveness of the OMNI-RES (0–10) Scale and the electromyographic signal for monitoring changes in the movement velocity were examined during a set to muscular failure using different percentages of 1 repetition maximum (1RM) in the parallel squat exercise (PSQ). Twelve men (26.3 ± 5.8 years) were evaluated on 8 separate days with 48 hours of rest between sessions. After determining the 1RM value, participants underwent 7 tests until achieving muscular failure with the following percentage ranges: 30 to <40%, 40 to <50%, 50 to <60%, 60 to <70%, 70 to <80%, 80 to <90%, and >90%. An optical rotary encoder measured mean accelerative velocity (MAV), and the OMNI-RES (0–10) Scale was used to express the rating of perceived exertion (RPE) after every repetition of each set. In addition, the normalized root mean square signal of the surface electromyography (N-EMG) was calculated for the vastus medialis muscle. The RPE expressed after the first repetition and when the maximum value of MAV was achieved along the sets was lower (p < 0.001, d > 0.8) than the RPE that corresponded to a 10% drop in MAV and at failure. In addition, the initial RPE was useful to distinguish different loading zones by anchoring the OMNI-RES value to the magnitude of the relative load (<60%, 60 to <70% or ≤70% 1RM). Similar patterns were observed using the N-EMG. In conclusion, apart from differentiating between relative loads during a set to failure in the PSQ, the RPE and the N-EMG can both reflect changes associated with the initial, maximal, 10% drop in movement velocity and the muscular failure.
Cholinergic, But Not Dopaminergic or Noradrenergic, Enhancement Sharpens Visual Spatial Perception in Humans

Published: March 2017

The neuromodulator acetylcholine modulates spatial integration in visual cortex by altering the balance of inputs that generate neuronal receptive fields. These cholinergic effects may provide a neurobiological mechanism underlying the modulation of visual representations by visual spatial attention. However, the consequences of cholinergic enhancement on visuospatial perception in humans are unknown. We conducted two experiments to test whether enhancing cholinergic signaling selectively alters perceptual measures of visuospatial interactions in human subjects. In Experiment 1, a double-blind placebo-controlled pharmacology study, we measured how flanking distractors influenced detection of a small contrast decrement of a peripheral target, as a function of target-flanker distance. We found that cholinergic enhancement with the cholinesterase inhibitor donepezil improved target detection, and modeling suggested that this was mainly due to a narrowing of the extent of facilitatory perceptual spatial interactions. In Experiment 2, we tested whether these effects were selective to the cholinergic system or would also be observed following enhancements of related neuromodulators dopamine or norepinephrine. Unlike cholinergic enhancement, dopamine (bromocriptine) and norepinephrine (guanfacine) manipulations did not improve performance or systematically alter the spatial profile of perceptual interactions between targets and distractors. These findings reveal mechanisms by which cholinergic signaling influences visual spatial interactions in perception and improves processing of a visual target among distractors, effects that are notably similar to those of spatial selective attention.SIGNIFICANCE STATEMENTAcetylcholine influences how visual cortical neurons integrate signals across space, perhaps providing a neurobiological mechanism for the effects of visual selective attention. However, the influence of cholinergic enhancement on visuospatial perception remains unknown. Here we demonstrate that cholinergic enhancement improves detection of a target flanked by distractors, consistent with sharpened visuospatial perceptual representations. Furthermore, whereas most pharmacological studies focus on a single neurotransmitter, many neuromodulators can have related effects on cognition and perception. Thus, we also demonstrate that enhancing noradrenergic and dopaminergic systems does not systematically improve visuospatial perception or alter its tuning. Our results link visuospatial tuning effects of acetylcholine at the neuronal and perceptual levels and provide insights into the connection between cholinergic signaling and visual attention.
Cued Memory Retrieval Exhibits Reinstatement of High Gamma Power on a Faster Timescale in the Left Temporal Lobe and Prefrontal Cortex

Converging evidence suggests that reinstatement of neural activity underlies our ability to successfully retrieve memories. However, the temporal dynamics of reinstatement in the human cortex remain poorly understood. One possibility is that neural activity during memory retrieval, like replay of spiking neurons in the hippocampus, occurs at a faster timescale than during encoding. We tested this hypothesis in 34 participants who performed a verbal episodic memory task while we recorded high gamma (62–100 Hz) activity from subdural electrodes implanted for seizure monitoring. We show that reinstatement of distributed patterns of high gamma activity occurs faster than during encoding. Using a time-warping algorithm, we quantify the timescale of the reinstatement and identify brain regions that show significant timescale differences between encoding and retrieval. Our data suggest that temporally compressed reinstatement of cortical activity is a feature of cued memory retrieval.SIGNIFICANCE STATEMENTWe show that cued memory retrieval reinstates neural activity on a faster timescale than was present during encoding. Our data therefore provide a link between reinstatement of neural activity in the cortex and spontaneous replay of cortical and hippocampal spiking activity, which also exhibits temporal compression, and suggest that temporal compression may be a universal feature of memory retrieval.

El riesgo de la judicialización en España
Authors: Cámara Ruiz Juan 
Published: March 2017

Si el riesgo de judicialización puede predicarse de los tribunales en general, en el caso del Tribunal Constitucional puede alcanzar una relevancia y una repercusión mayor debido a la trascendencia de su jurisprudencia. El vigente régimen de admisibilidad del recurso de amparo ha provocado un cambio en la naturaleza del recurso, por haber asumido el TC ese nuevo papel que tanto le acerca a la labor propia del Legislador y le va alejando de los sujetos jurídicos perjudicados. Cada vez, es mayor el peligro de la extralimitación del Poder ejecutivo y la consiguiente instrumentalización de la Justicia, con tal de obtener resoluciones que avalen su labor ejecutiva.

Biologic Remodeling of Periodontal Dimensions of Areas Treated With Gingival Augmentation Procedure: A 25‐Year Follow‐Up Observation
Authors: Agudio Giancarlo , Chambrone Leandro , Pini Prato Giovanpaolo 
Published: March 2017

Background: The role of keratinized tissue (KT) for maintenance of periodontal health has been debated for many years. This study assesses the long‐term “biologic remodeling” of periodontal dimensions of teeth treated with free gingival grafts (FGGs) compared with adjacent/untreated teeth.Methods: Seventy‐four patients with at least one site showing absence or a reduced amount of attached gingiva associated with gingival recession (GR) at baseline were treated with FGGs in a private practice. Patient/tooth/site‐associated variables were recorded for each patient (treated and mesial/distal adjacent teeth) at baseline (T0), 6 months after surgery (T1), during the follow up period (T2) (mean 15.3 years), and at the end of the follow‐up period (T3) over 25 years. Parametric, non‐parametric, and mixed effects logistic regression statistics were used throughout the study.Results: A total of 182 teeth submitted to FGGs were compared with 247 untreated/adjacent teeth. The majority of treated teeth (n = 152; 83.5%) showed GR depth (GRD) reduction (P <0.001). Conversely, untreated/adjacent teeth displayed GRD increase at T3 (P <0.001). Statistically significant KT band contraction was also found at treated sites, whereas adjacent sites presented small clinical improvements (P <0.001). The total root‐coverage esthetic score of the areas including treated and adjacent untreated teeth improved from T2 to T3 (P <0.001). Some independent variables, such as age, tooth type, and GRD at T1 seem to influence GRD and KT changes over time.Conclusions: Soft tissue augmentation procedures may modify the biologic remodeling of periodontal dimensions over time associated with aging. Use of FGGs may promote more favorable KT dimensions and improve marginal tissue recession.
