1-Generic splittings of computably enumerable degrees.Guohua Wu -2006 -Annals of Pure and Applied Logic 138 (1):211-219.detailsSay a set Gω is 1-generic if for any eω, there is a string σG such that {e}σ↓ or τσ↑). It is known that can be split into two 1-generic degrees. In this paper, we generalize this and prove that any nonzero computably enumerable degree can be split into two 1-generic degrees. As a corollary, no two computably enumerable degrees bound the same class of 1-generic degrees.
Degrees containing members of thin Π10 classes are dense and co-dense.Rodney G. Downey,Guohua Wu &Yue Yang -2018 -Journal of Mathematical Logic 18 (1):1850001.detailsIn [Countable thin [Formula: see text] classes, Ann. Pure Appl. Logic 59 79–139], Cenzer, Downey, Jockusch and Shore proved the density of degrees containing members of countable thin [Formula: see text] classes. In the same paper, Cenzer et al. also proved the existence of degrees containing no members of thin [Formula: see text] classes. We will prove in this paper that the c.e. degrees containing no members of thin [Formula: see text] classes are dense in the c.e. degrees. We will (...) also prove that the c.e. degrees containing members of thin [Formula: see text] classes are dense in the c.e. degrees, improving the result of Cenzer et al. mentioned above. Thus, we obtain a new natural subclass of c.e. degrees which are both dense and co-dense in the c.e. degrees, while the other such class is the class of branching c.e. degrees 113–130] for nonbranching degrees and [T. A. Slaman, The density of infima in the recursively enumerable degrees, Ann. Pure Appl. Logic 52 155–179] for branching degrees). (shrink)
Nonhemimaximal degrees and the high/low hierarchy.Fang Chengling &WuGuohua -2012 -Journal of Symbolic Logic 77 (2):433-446.detailsAfter showing the downwards density of nonhemimaximal degrees, Downey and Stob continued to prove that the existence of a low₂, but not low, nonhemimaximal degree, and their proof uses the fact that incomplete m-topped degrees are low₂ but not low. As commented in their paper, the construction of such a nonhemimaximal degree is actually a primitive 0''' argument. In this paper, we give another construction of such degrees, which is a standard 0''-argument, much simpler than Downey and Stob's construction mentioned (...) above. (shrink)
Benefits of non-work interactions with your supervisor: Exploring the bottom-up effect of employee boundary blurring behavior on abusive supervision.Luyuan Jiang,Guohua He,Hansen Zhou,Laijie Yang,Xiaolan Li,Wenpu Li &Xin Qin -2022 -Frontiers in Psychology 13.detailsAbusive supervision has long been found to have remarkably negative impacts on individual and organizational outcomes. Accordingly, prior studies have explored many organizational and supervisory predictors of abusive supervision and offered several interventions to reduce it. However, extant research lacks the bottom-up perspective to explore how employees can act to reduce abusive supervision, which is an important factor that enriches abusive supervision literature and helps employees protect themselves from being abused. Drawing on self-disclosure theory, we develop a model of whether (...) and how employee boundary blurring behavior may protect them from being abused by their supervisors. Specifically, we conducted two studies to test the theoretical model, including a scenario-based experimental study and a multi-source, multi-wave field study. The results reveal a negative indirect effect of employee boundary blurring behavior on abusive supervision via supervisor liking toward the employee. By uncovering employee boundary blurring behavior as an antecedent of abusive supervision, we enrich the abusive supervision literature with a bottom-up behavioral strategy for employees to proactively protect themselves from being abused. We hope our findings will encourage future studies to identify boundary conditions and other solutions for employees to minimize the risk of being abused. (shrink)
Highness, locally noncappability and nonboundings.Frank Stephan &Guohua Wu -2013 -Annals of Pure and Applied Logic 164 (5):511-522.detailsIn this paper, we improve a result of Seetapun and prove that above any nonzero, incomplete recursively enumerable degree a, there is a high2 r.e. degree c>ac>a witnessing that a is locally noncappable . Theorem 1.1 provides a scheme of obtaining high2 nonboundings , as all known high2 nonboundings, such as high2 degrees bounding no minimal pairs, high2 plus-cuppings, etc.
What are the changes in basketball shooting pattern and accuracy in National Basketball Association in the past decade?Feng Wang &Guohua Zheng -2022 -Frontiers in Psychology 13.detailsThe main research question addressed in this study is if and how the shooting pattern and field-goal accuracy have changed in the NBA league in the past decade. This study analyzes NBA game data from the 2011–2012 regular season to the 2020–2021 season. Field goal attempts are grouped into five categories by the shooting distance. The Mann-Kendall trend test was employed to examine if changes are statistically significant over the years. Sixteen equal segments in one basketball game, each with 3 (...) min, were analyzed to examine the shooting pattern in different game segments. Results reveal an increasing trend in the percentage of 3-pointer shooting, which has nearly doubled from 22 to 39%. Meanwhile, the percentage of field goals within the range of 16–24 ft has decreased from 20 to 10%. Field-goal accuracy has shown an increasing trend for all shooting distances except for the 3-pointer shooting. The second and fourth 3-min within each quarter have the highest number of field goals. The first quarter has a higher shooting accuracy than the rest three quarters. In addition, results reveal that the last 3-min in each quarter has the lowest shooting accuracy. Reasons for the patterns of field goals in different segments are discussed from the perspective of game rule changes, the fatigue effects, and coaches’ game strategies. The reasons for changes in activity level and performance in different quarters are also discussed. This study offers new insights into the changes in basketball shooting patterns and accuracy in NBA games in the past decade. Practical meanings of this study for basketball players, coaches, and sports psychologists, as well as the strength and limitations of this study, are discussed. (shrink)
Bounding computably enumerable degrees in the Ershov hierarchy.Angsheng Li,Guohua Wu &Yue Yang -2006 -Annals of Pure and Applied Logic 141 (1):79-88.detailsLachlan observed that any nonzero d.c.e. degree bounds a nonzero c.e. degree. In this paper, we study the c.e. predecessors of d.c.e. degrees, and prove that given a nonzero d.c.e. degree , there is a c.e. degree below and a high d.c.e. degree such that bounds all the c.e. degrees below . This result gives a unified approach to some seemingly unrelated results. In particular, it has the following two known theorems as corollaries: there is a low c.e. degree isolating (...) a high d.c.e. degree [S. Ishmukhametov, G. Wu, Isolation and the high/low hierarchy, Arch. Math. Logic 41 259–266]; there is a high d.c.e. degree bounding no minimal pairs [C.T. Chong, A. Li, Y. Yang, The existence of high nonbounding degrees in the difference hierarchy, Ann. Pure Appl. Logic 138 31–51]. (shrink)
On a problem of Ishmukhametov.Chengling Fang,Guohua Wu &Mars Yamaleev -2013 -Archive for Mathematical Logic 52 (7-8):733-741.detailsGiven a d.c.e. degree d, consider the d.c.e. sets in d and the corresponding degrees of their Lachlan sets. Ishmukhametov provided a systematic investigation of such degrees, and proved that for a given d.c.e. degree d > 0, the class of its c.e. predecessors in which d is c.e., denoted as R[d], can consist of either just one element, or an interval of c.e. degrees. After this, Ishmukhametov asked whether there exists a d.c.e. degree d for which the class R[d] (...) has no minimal element. We give a positive answer to this question. (shrink)
Degrees of d. c. e. reals.Rod Downey,Guohua Wu &Xizhong Zheng -2004 -Mathematical Logic Quarterly 50 (4-5):345-350.detailsA real α is called a c. e. real if it is the halting probability of a prefix free Turing machine. Equivalently, α is c. e. if it is left computable in the sense that L = {q ∈ ℚ : q ≤ α} is a computably enumerable set. The natural field formed by the c. e. reals turns out to be the field formed by the collection of the d. c. e. reals, which are of the form α—β, where (...) α and β are c. e. reals. While c. e. reals can only be found in the c. e. degrees, Zheng has proven that there are Δ02 degrees that are not even n-c. e. for any n and yet contain d. c. e. reals, where a degree is n-c. e. if it contains an n-c. e. set. In this paper we will prove that every ω-c. e. degree contains a d. c. e. real, but there are ω + 1-c. e. degrees and, hence Δ02 degrees, containing no d. c. e. real. (shrink)
An almost-universal cupping degree.Jiang Liu &Guohua Wu -2011 -Journal of Symbolic Logic 76 (4):1137-1152.detailsSay that an incomplete d.r.e. degree has almost universal cupping property, if it cups all the r.e. degrees not below it to 0′. In this paper, we construct such a degree d, with all the r.e. degrees not cupping d to 0′ bounded by some r.e. degree strictly below d. The construction itself is an interesting 0″′ argument and this new structural property can be used to study final segments of various degree structures in the Ershov hierarchy.
Joining to high degrees via noncuppables.Jiang Liu &Guohua Wu -2010 -Archive for Mathematical Logic 49 (2):195-211.detailsCholak, Groszek and Slaman proved in J Symb Log 66:881–901, 2001 that there is a nonzero computably enumerable (c.e.) degree cupping every low c.e. degree to a low c.e. degree. In the same paper, they pointed out that every nonzero c.e. degree can cup a low2 c.e. degree to a nonlow2 degree. In Jockusch et al. (Trans Am Math Soc 356:2557–2568, 2004) improved the latter result by showing that every nonzero c.e. degree c is cuppable to a high c.e. degree (...) by a low2 c.e. degree b. It is natural to ask in which subclass of low2 c.e. degrees can b in Jockusch et al. (Trans Am Math Soc 356:2557–2568, 2004) be located. Wu proved in Math Log Quart 50:189–201, 2004 that b can be cappable. We prove in this paper that b in Jockusch, Li and Yang’s result can be noncuppable, improving both Jockusch, Li and Yang, and Wu’s results. (shrink)
Research on the Impact of Technological Finance on Financial Stability: Based on the Perspective of High-Quality Economic Growth.Lu Shen,Guohua He &Huan Yan -2022 -Complexity 2022:1-15.detailsThis paper investigates the relationship between technological finance, high-quality economic growth, and financial stability. Based on data of 30 provinces collected between 2004 and 2017, this paper adopts the method of factor analysis to construct comprehensive indexes of technological finance and financial stability before calculating green total factor productivity as the index of high-quality development, using the CRS Multiplicative Model. Then it constructs the spatial SAC model and PVAR model for analyses of the just-mentioned relationship based on the total sample (...) of the nation and regional samples in eastern, middle, and western China, respectively. The results reveal that All samples, whether the total national samples or regional samples of eastern, middle, and western China demonstrate the positive influence of technological finance on high-quality economic development, with an obvious spatial spillover effect. The impact factor is the highest in the eastern region, while the western region holds the lowest factor among the three. Judging by the general national sample, technological finance has an obvious negative shock effect on financial stability within a short period, but the effect gradually dwindles as time goes by. This rule applies to the sample of the eastern region, as its technological finance poses a short-time negative shock effect on financial stability, before gradually diminishing to 0. Neither western nor middle regions have displayed an obvious shock impact on financial stability. (shrink)

Adhipati, Yogācāra Intersubjectivity, and Soteriology in Kuiji’s Commentaries.Jessica X. Zu -forthcoming -Sophia:1-24.detailsThis study sheds light on a key concept of Yogācāra intersubjectivity that played a significant role in medieval Chinese Yogācāra. Specifically, it analyzes how Kuiji 窺基 (632–682) reinterprets adhipati (activating and amplifying influence; Ch: zengshang 增上 or zengshang li 增上力 or zengshang yuan 增上緣) to account for intersubjective karmic interactions across different lifeworlds in the events of teaching and killing.As this line of investigation shows, Kuiji’s theory of adhipati attempts to sidestep the entanglement of the problems of intersubjectivity and incommensurable (...) worlds in Yogācāra. Extant scholarship on intersubjectivity often presumes one spatio-temporal world populated by sentient beings and insentient objects, which is fundamentally at odds with the Yogācāra tenet that each mental stream generates its distinct lifeworld. To address the pragmatic question of how different mental continuums of consciousnesses can impinge into each other’s lifeworlds, Kuiji employed adhipati in a specific way to account for intersubjective interplay across different, potentially incommensurable worlds. In this framing of intersubjectivity, the problem of one world or many worlds is explained non-dualistically: these lifeworlds are neither the same nor different, neither one nor many, but karmically interconnected.Expanding on recent discussions of the puzzle of intersubjectivity in Yogācāra, this paper shows that Kuiji’s deployment of adhipati provides an account of genuine intersubjectivity in which different mental continuums are recognized as subjects and engage in causal interactions among different spatio-temporal worlds. In Kuiji’s framing, this genuine intersubjectivity gives rise to the sense of one shared world. (shrink)
Just awakening: yogācāra social philosophy in modern China.Jessica X. Zu -2025 - New York: Columbia University Press.detailsYogācāra, one of the two principal schools of Indian Mahayana Buddhism, arose in the first or second century CE and was introduced into Tibet and China in the fourth and fifth centuries CE, where it quickly became a dominant form. Roughly comparable to phenomenology in the West (and acknowledged as an influence by Husserl and Merleau-Ponty), it rejects ontology in favor of experiential foundations and claims that knowledge is produced by individual or collective consciousness. In the late nineteenth through mid-twentieth (...) centuries, in response to the introduction of evolutionary theory and its specious corollary of Social Darwinism, Chinese Buddhists asked what kind of philosophy could both accommodate the scientific enterprise and enable a better understanding of a social dynamics that could oppose racial, class, and colonial hierarchies. They turned to yogācāra; thinkers like Lu Cheng called into question unexamined materialist and empiricist assumptions that naturalized moral/rational egoism and hierarchy. He argued that scientific and social-scientific findings could be established epistemically by intersubjective agreement, coherence, and causal efficacy. Jessica Zu recovers this influential yogācāra movement in premodern and modern China and in turn asks why it has had no purchase in the West. Part of the reason is the epistemic policing of the boundary between philosophy and religion and its colonialist privileging of Western thought-we don't speak of Kant or Hegel as "Christian" philosophers. If we expand our conceptual universe to include world philosophies, antiessentialist Chinese process thinking is a valuable resource for combating systemic oppression and fostering social justice.
