Kirby, J. (2018). The gamma paradoxes : an analysis of the fourth book of Aristotle’s Metaphysics. Lanham: Lexington Books.

Description: In the fourth book, Book Gamma, of his Metaphysics, Aristotle treats the nature and range of science, outlines an approach to ontology, formulates and defends first principles, articulates an influential conception of truth, and defends his views against his relativist contemporaries. In The Gamma Paradoxes, Jeremy Kirby analyzes Book Gamma and introduces debates – or paradoxes – such as relativism versus the idea of a ready-made world, the possibility of true contradictions, the nature and possibility of metaphysics, and the limits of thought and logic. These paradoxes raise issues of contemporary interest: the which may be known a priori; the relationship between mind, language, and world; and, inter alia, the values of logic. Book Gamma is the mise-en-scène for Aristotle’s investigation into the perennial question, the nature of substance, and the denouement, as unmoved mover.

Abstract: The construction of Kariba Dam in 1958 ignited a legacy of livelihood insecurity and chronic liminality that reverberated through subsequent generations. A community under one chief was split into two marginal resettlement sites more than 200 km apart. Sixty years after the dam’s construction, and following a series of cyclical shifts between access to and alienation from international development programming, the World Bank has returned to initiate the new Bottom Road, which at last reconnects these two communities. It has also released funds for a new irrigation development and support program. Research presented here suggests that, while the Bottom Road is spurring economic growth, it is also delivering capitalized outsiders, eager to claim land and water resources from long-resident Gwembe Tonga farmers. Analysis of two commercial agriculture/irrigation schemes, at the road’s southern and northern terminuses, reveals that new infrastructure often leads to rapid natural resource alienation and livelihood upheaval. Integrating the lens of chronic liminality with the hydrosocial cycle, we situate these projects within a broader regional history of land and water privatization and reveal how water-linked development interventions produce vulnerabilities for particular segments of the local population.

Abstract: Learning more about the role of the academic department in LACs may improve faculty selection, development, support, and retention. Knowledge based on research about other institution types cannot be assumed to be generalizable to LACs. We know little about departmental contexts of faculty work in liberal arts colleges (LACs). The purpose of this exploratory qualitative study was to understand the department as an organizational context of faculty work in LACs, relying on the concept of positive organizational behavior. Findings from analysis of interview data from 55 liberal arts faculty members highlight the influence of three areas—culture, colleagues, and leadership.

Abstract: We conduct sandstone-composition analysis, U-Pb detrital-zircon dating, and apatite fission-track thermochronology to determine how basin development was associated with the Cenozoic deformation across central Tibet. Our results are consistent with a two-stage basin development model: first a single fluvial-lacustrine system formed (i.e., Paleo-Qaidam basin) in between two thrust belts (i.e., the Fenghuoshan and Qilian Shan thrust belts) in the Paleogene, which was later partitioned into two sub-basins in the Neogene by the Kunlun transpressional system and its associated uplift. The southern sub-basin (i.e., Hoh Xil basin) strata have detritalzircon age populations at 210-300 Ma and 390-480 Ma for the Eocene strata and at 220-310 Ma and 400-500 Ma for the early Miocene strata; petrologic analysis indicates that the late Cretaceous-Eocene strata were recycled from the underlying Jurassic rocks. The northern sub-basin (i.e., Qaidam basin) strata yield detrital-zircon age clusters at 210-290 Ma and 370-480 Ma in the Eocene, 220-280 Ma and 350-500 Ma in the Oligocene, 250-290 Ma and 395-510 Ma in the Miocene, and 225-290 Ma and 375-480 Ma in the Pliocene. Proterozoic ages of the detrital zircon are most useful for determining provenance: the pre-Neogene Hoh Xil and Qaidam strata all contain the distinctive age peaks of similar to 1800 Ma and similar to 2500 Ma from the Songpan-Ganzi terrane south of the Kunlun fault, whereas detrital zircon of this age is absent in the Neogene Qaidam strata suggesting the emergence of a topographic barrier between the two basins. This inference is consistent with our fission-track thermochronological data from the Eastern Kunlun Range that suggest rapid cooling within the range did not start until after 30-20 Ma. Our new data support the Paleo-Qaidam hypothesis that requires the Hoh Xil and Qaidam basins were parts of a single Paleogene basin bounded by the Qilian Shan and Fenghuoshan thrust belts.

Abstract: Determining the impact chronology of the Moon is an important yet challenging problem in planetary science even after decades of lunar samples and other analyses. In addition to crater counting statistics, orbital data, and dynamical models, well-constrained lunar sample ages are critical for proper interpretation of the Moon’s impact chronology. To understand which properties of lunar impact glasses yield well-constrained ages, we evaluated the compositions and sizes of 119 Apollo 14, 15, 16, and 17 impact glass samples whose compositions and 40Ar/39Ar ages have already been published, and we present new data on 43 others. These additional data support previous findings that the composition and size of the glass are good indicators of the quality of the age plateau derived for each sample. We have further constrained those findings: Glasses of ≥200 μm with a fraction of non-bridging oxygens (X(NBO)) of ≥0.23 and a K2O (wt%) of ≥0.07 are prime candidates for argon analyses and more likely to yield well-constrained 40Ar/39Ar ages. As a result, science resulting from impact glass analyses is maximized while analytical costs per glass are minimized. This has direct implications for future analyses of glass samples for both those in the current lunar collection and those that have yet to be collected.

Abstract: The effects of varying concentrations (ranging from 0 to 10 μM) of two different metals that is, iron (Fe) and copper (Cu) on indigenous bacterial populations and their hydrolytic enzyme activities within the bacterioplankton assemblages from the surface waters of the Kalamazoo River were examined under controlled microcosm conditions. The two metals were added to water samples collected from the Kalamazoo River and examined for bacterial abundance and leucine aminopeptidase activities at various time intervals over a 48 h incubation period in the dark. Results revealed no concentration effects on the bacterial populations in the presence of both Fe and Cu, although the bacterial numbers varied significantly over time in both microcosms. Conversely, leucine aminopeptidase activities based on post-hoc tests using Bonferroni correction revealed significant differences to increasing concentrations of both metals over the study period. These results further validate previous knowledge regarding the importance of various metal ions in regulating bacterial community structures and also suggest that aminopeptidase have the potential of effectively functioning using diverse trace and heavy metals as extracellular peptidase cofactors in aquatic systems.

Abstract: The interdisciplinary topic of creativity is both fascinating and controversial. In this review, we begin by highlighting the many ways that researchers conceptualize and define creativity, focusing in particular on the difference between everyday creativity and creativity associated with exceptional breakthroughs in thinking. In addition, we discuss the role of divergent and convergent creativity and the role that domain knowledge plays in creativity. Furthermore, we highlight how specific factors such as individual differences and time of day influence creativity. We conclude by discussing the impact of current educational practices on creativity in psychology classrooms.

Abstract: Though the concept of Harappan homogeneity along with regional diversity is now a well established fact, still the development and spread of Harappan civilization is a puzzle to be solved. Recent explorations at the site of Janan, situated on the Khadir island of Kachchh district of Gujarat have brought to light significant evidence of Early Harappan period. The discovery of Pre-Prabhas pottery, Anarta pottery, Pre Urban Harappan Sindh pottery, Rohri chert blades and other important artefacts give evidence of contact between Kachchh, North Gujarat, Saurashtra and Sindh, Pakistan before the Integration era of Indus Civilization which is important since till date Datrana, situated in North Gujarat and Prabhas Patan (Somnath) in Saurashtra have given similar evidences. This paper is a comprehensive analysis of the lithic assemblage recovered from the site which gives evidence of crested guiding ridge technique being used for the blade manufacturing process in terms of presence of blades as well as cores which show crested ridges running along their longer axis. The presence of Rohri chert blade fragments without any lithic debitage of the same raw material strongly suggests that these blades were imported to the site. These findings are vital in establishing link between Sindh and Gujarat during Regionalization era of Harappan civilization.

Abstract: The Miconieae (Melastomaceae) are a strictly Neotropical group comprising over 1900 species. The tribe is characterized by inflorescences that are terminal or axillary, but not cauliflorous (except a few species of Charianthus, Clidemia, and Mecranium), flowers subtended by only one pair of bracteoles (or none at all), with anthers that lack a pedoconnective, leaves without long acicular raphides, and berry fruits. Generic delimitations within the Miconieae have been notoriously complex, and phylogenetic analyses have shown that Miconia is paraphyletic with many other genera embedded within it. These nested genera include Anaectocalyx, Calycogonium, Catocoryne, Charianthus, Clidemia, Conostegia, Killipia, Leandra, Maieta, Mecranium, Necramium, Ossaea, Pachyanthus, Pleiochiton, Sagraea, Tetrazygia, and Tococa. In the absence of a workable solution that allows the subdivision of the tribe into smaller, morphologically recognizable and monophyletic genera, it has been previously proposed that only one genus be recognized in the tribe. Here we present the necessary taxonomic and nomenclatural changes necessary to recognize Miconia as the sole genus within Miconieae.

Abstract: Euroscepticism has been a persistent part of the European integration process over the last several decades (Usherwood and Startin [2013]. Euroscepticism as a persistent phenomenon. JCMS: Journal of Common Market Studies, 51, 1?16). Scholars have proposed various theories to explain resistance to integration by drawing upon economic, political and cultural theories. In this paper, I ask whether Euroscepticism is a by-product of rural-urban divisions, which influences one’s perception of the economy, one?s trust of transnational politics and one’s cultural identity. However, geographical variables have never been tested in the presence of these more well-established Euroscepticism predictors. Here, I use the European Social Survey to compare the predictive power of economic, political, cultural and geographical variables on two forms of Euroscepticism: trust in European Parliament and the belief that integration has gone too far. Multilevel mixed-effects regression models demonstrate that trust in the European Parliament is indeed higher in big cities, but overall, place of residence is not a strong predictor of Euroscepticism. Among other theories, I find that cultural variables are more meaningful than economics or politics. I finally conclude with a discussion of the EU’s future.

Abstract: Competition horses are susceptible to high stress levels. Lavender aromatherapy (LA) is legal, has the potential to reduce stress, and is a relatively unexplored area of equine physiology. We hypothesis that LA has positive effects on helping horses cope with stress. We predict that these effects can be measured in lowered cortisol, norepinephrine, and heart rate levels in horses that have been subjected to lavender aromatherapy during a stressor. Eight horses were used in a crossover study and were transported for 15 minutes in a horse trailer. During the trailer ride (stressor), the horses received water aromatherapy as the control, and LA as the treatment. Three measurements of heart rates and blood draws were taken on each horse: (1) baseline—before loading into the trailer, (2) stressed—immediately after the trailer ride, and (3) recovery—50 minutes after the trailer ride. The blood samples were used to quantify serum cortisol levels. In both the control and treatment horses, the average difference between the baseline and stressed measurements of heart rate (HR) and cortisol increased when the horses were transported (control HR = 10.6 b/m ± 2.6 standard error [SE]; treatment HR = 9.3 b/m ± 2.6 SE; control cortisol = 3,747.2 pg/uL ± 864.2 SE; treatment cortisol = 2,511.8 pg/uL ± 1009.9 SE). In the control and treatment horses, there was no difference in the HRs of the control and treatment horses (P-value = .37); there was a difference in cortisol levels (P = .038), which provides evidence to conclude that cortisol levels were lower in horses that were subjected to LA during a stressor.

Abstract: Early Christians searched the scriptures to find meaning in Jesus’ death. According to Donald Juel, their findings emerged from “messianic exegesis.” Following the rule of gezerah shewah, they interpreted passages reminiscent of Jesus in light of acknowledged messianic texts. This study focuses on twelve explicit christological citations in the Fourth Gospel: Exod. 12:46; Pss 22:18; 34:20; 41:9; 69:4, 9, 21; 118:25–26; Isa 6:10; 40:3; 53:1; and Zech. 9:9; 12:10. Johannine exegetes could have used “messianic exegesis” to justify interpreting them as prophecies about Jesus. The evidence that suggests that they did. Psalms 22; 69; 118 and Isa. 52:13—53:12—standard Christian proof texts—can be interpreted in light of a messianic psalm, Ps. 89. Messianic exegesis extends from them to Exod. 12; Pss. 34; 41; 118; Isa. 6:1–10; and Zech. 9:9; 12:0. John’s tandem quotations share significant catchwords, with each other and with Ps. 22. Furthermore, John’s narrative emphasizes catchwords like come, eyes, see, hate, lift up, and glorify. Apparently, John has searched the scriptures and found a Messiah who comes into the world, opening blind eyes but hated by those who cannot see. In the end, he is lifted up and glorified—on a Roman cross.

Abstract: Recent collections in the Sierra de Bahoruco represent a previously undescribed species of Miconia sect. Calycodomatia from the Greater Antillean Sandpaper clade. We herein describe the new species as Miconia clasei, provide a phylogenetic analysis to determine close relatives, and compare it morphologically with its closest relatives and phenetically similar taxa. We also expand on previous analyses of the Sandpaper clade, including more individuals per species than previously analyzed, and two taxa never before analyzed phylogenetically. We show that several species within the Sandpaper clade are indeed cladospecies, while others appear to be non-monophyletic.

Abstract: Families and the practices of kinship through which they are constructed and reproduced have been central to Mark Kenoyer’s interpretive approach to the archaeology of the Indus Civilization (2600-1900 BC). The recognition that different Indus craft technologies were likely undertaken and controlled by differently organized families independent of centralized political control, for example, has been deeply influential in subsequent discussions of Indus social dynamics. In this contribution, I apply and build upon these insights to explore the social implications of kinship practices in Harappan Gujarat. The model developed here proposes that kinship practices instrumentally structured movement of people, goods, and wealth within and beyond the region. Specifically, it suggests that resource owning, labor controlling, exogamous descent groups may have been the major source of authority at walled settlements in Harappan Gujarat. The marriage practices of families organized in this way would have further structured material transfers consistent with the observed distribution of Harappan material culture as well as aspects of the pastoral economy in the region. While this perspective is necessarily speculative at present, it nevertheless productively suggests specific hypotheses amendable to evaluation with empirical evidence going forward.

Abstract: A 3-uniform complete hypergraph of order n has vertex set {1, 2, . . . , n} and, as its edge set, the set of all possible subsets of size 3. A 4-cycle in this hypergraph is v1, e1, v2, e2, v3, e3, v4, e4, v1 where {v1, v2, v3, v4} are distinct vertices and {e1, e2, e3, e4} are distinct 3-edges such that vi, vi+1 ei for i = 1, 2,3 and v4, v1 e4 (also known as a Berge cycle). A decomposition of a hypergraph is a partition of its edge set into edge-disjoint subsets. In this paper, we give necessary and sufficient conditions for a decomposition of the complete 3-uniform hypergraph of order n into 4-cycles.

Verduzco-Baker, L. (2018). Modified Brave Spaces: Calling in Brave Instructors. Sociology of Race and Ethnicity, 4(4), 585-592.

Abstract: In recent years, instructors teaching about controversial issues such as race and ethnicity have drawn increasingly on the ideas of “safe” and “brave” spaces to encourage and facilitate dialogue during class discussion. Unfortunately, these concepts have limits when taken out of the dialogic social justice workshop and course contexts where they were initially developed—contexts with very different power dynamics than those in conventional college classrooms. I review these differences and their limits, then propose an alternate set of strategies to better adapt the “brave space” concept to conventional, disciplinary-specific, academic courses. Specifically, I urge instructors to avoid relying on marginalized students to publicly share personal experiences of oppression, to practice “calling in” which offers a productive way to challenge problematic beliefs or statements in the classroom, and to model being “brave” in their own responses when they are “called in” themselves. These strategies aim to give instructors more confidence in their ability to handle difficult conversations, while ensuring they do not burden some students or allow others to appropriate the language of “safety” to avoid challenges.

Abstract: Symmetric patterns can be understood mathematically as the resulting action of a symmetry group on a base motif. In each symmetry group, all its elements can be represented by transformation matrices. Using the subgroup structure of a base symmetry group, patterns can be created that have some integration into the overall symmetry. Examples of this process are shown for two dihedral groups and a wallpaper group.

Abstract: In a world of declining biodiversity, monitoring is becoming crucial. Molecular methods, such as metabarcoding, have the potential to rapidly expand our knowledge of biodiversity, supporting assessment, management, and conservation. In the marine environment, where hard substrata are more difficult to access than soft bottoms for quantitative ecological studies, Artificial Substrate Units (ASUs) allow for standardized sampling. We deployed ASUs within five regional seas (Baltic Sea, Northeast Atlantic Ocean, Mediterranean Sea, Black Sea, and Red Sea) for 12–26 months to measure the diversity and community composition of macroinvertebrates. We identified invertebrates using a traditional approach based on morphological characters, and by metabarcoding of the mitochondrial cytochrome oxidase I (COI) gene. We compared community composition and diversity metrics obtained using the two methods. Diversity was significantly correlated between data types. Metabarcoding of ASUs allowed for robust comparisons of community composition and diversity, but not all groups were successfully sequenced. All locations were significantly different in taxonomic composition as measured with both kinds of data. We recovered previously known regional biogeographical patterns in both datasets (e.g., low species diversity in the Black and Baltic Seas, affinity between the Bay of Biscay and the Mediterranean). We conclude that the two approaches provide complementary information and that metabarcoding shows great promise for marine monitoring. However, until its pitfalls are addressed, the use of metabarcoding in monitoring of rocky benthic assemblages should be used in addition to classical approaches rather than instead of them.

Abstract: Colchicine analogues in which an azo group is incorporated into a molecule containing the key pharmacophore of colchicine, have found particular utility as switchable tubulin binding chemotherapeutics. Combretastatin is a related compound containing a stilbene fragment that shows different bioactivity for the cis and trans isomers. We have performed cell assays on 17 new compounds structurally related to a previously reported azo-analogue of combretastatin. One of these compounds showed enhanced potency against HeLa (IC50 = 0.11 μM) and H157 cells (IC50 = 0.20 μM) for cell studies under 400 nm irradiation and the highest photoactivity (IC50 with irradiation/IC50 in dark = 550). We have performed docking and physicochemical studies of this new compound (7). Kinetic studies in water reveal a longer half-life for the cis isomer of 7 which may be one factor responsible for the better IC50 values in cell assays and the improved photoresponsive behavior.

Abstract: Unlike people suffering from most physical afflictions, those with mental illness often face prejudice. This study examines the interplay of several key social and personal predictors of mental illness prejudice: SES, empathy, mental illness knowledge, and personal acquaintance with the mentally ill. As expected, analyses showed that higher subjective (although not objective) SES, lower levels of empathy, and lower levels of knowledge about mental illness all predicted increased prejudice against people suffering from clinical depression and nondescript mental illness—although not against people suffering from schizophrenia. Path analyses showed evidence for a mediating role of knowledge and empathy in the link between SES and prejudice. Implications of these findings for ways to diffuse mental illness prejudice are discussed.

Abstract: The distributions of 40Ar/39Ar-derived ages of impact glass spherules in lunar regolith samples show an excess at <500 Ma relative to older ages. It has not been well understood whether this excess of young ages reflects an increase in the recent lunar impact flux or is due to a bias in the samples. We developed a model to simulate the production, transport, destruction, and sampling of lunar glass spherules. A modeled bias is seen when either (1) the simulated sampling depth is 10 cm, consistent with the typical depth from which Apollo soil samples were taken, or (2) when glass occurrence in the ejecta is limited to >10 crater radii from the crater, consistent with terrestrial microtektite observations. We suggest that the observed excess of young ages for lunar impact glasses is likely due to limitations of the regolith sampling strategy of the Apollo program, rather than reflecting a change in the lunar impact rate.

Abstract: The primary aim of this article is to provide a comprehensive review and elaboration of model matching and its theoretical propositions. Model matching explains and predicts individuals’ outcomes related to gameplay by focusing on the interrelationships among games’ systems of mechanics, relevant situations external to the game, and players’ mental models. Formalizing model matching theory in this way provides researchers a unified explanation for game-based learning, game performance, and related gameplay outcomes while also providing a theory-based direction for advancing the study of games more broadly. The propositions explicated in this article are intended to serve as the primary tenets of model matching theory. Considerations for how these propositions may be tested in future games studies research are discussed.
