Racial/Ethnic Minority Community College Students' Critical Consciousness and Social Cognitive Career Outcomes

A need exists to better understand how racial/ethnic minority students' critical consciousness development in response to marginalization may be involved in their educational and career development. We therefore examined the link between critical consciousness development and career decision self-efficacy and career outcome expectations among racial/ethnic minority community college students. Following social cognitive career theory's conceptual pillars, we developed a testable model integrating critical consciousness and social cognitive variables. This model was tested with 135 racially and ethnically diverse community college students. Data analysis included path analyses and tests of model fit using structural equation modeling. Results suggested that (a) higher critical agency is linked to higher career decision self-efficacy and outcome expectations and (b) critical action and reflection have a bidirectional link and predict higher critical agency. Implications for research and practice aiming to close educational and career gaps among racial/ethnic minorities are discussed.     

宗喀巴《密宗道次第广论》的哲学思想探析

宗喀巴指出，佛陀所创正法，唯在于“教”“证”两种，“教”是指佛教教理，“证”为修道中的证悟。宗喀巴《密宗道次第广论》具有鲜明的“教”与“证”相结合的特色。此著在“教”方面体现为本体论、佛性论、人生论、道德论、方法论等哲学思想，贯穿于《密宗道次第广论》的哲学主线是中观应成派一切诸法缘起性空论。通过灌顶、诵咒、观想及借助坛城、法器等修各种瑜伽，以亲证或体现这些哲学思想。诸如此类的哲学思想是《密宗道次第广论》所论述的各种修行实践的深刻内涵，而各种修行实践是其外在表现形式。     

Defender–Attacker Games with Asymmetric Player Utilities

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.     

Restricted minimax estimation in semiparametric linear models

Abstract

In this article we develop the minimax estimation approach of general linear models to the semiparametric linear models when the parameters are simultaneously constrained by an ellipsoid and linear restrictions. Combining sample information and prior constraints the minimax estimator is obtained and compared with partially least square estimator by theoretical and simulation methods.     

论全球气候治理中城市的角色转型——兼论中国困境与出路

从全球气候治理的1.0时期、2.0时期到3.0时期，城市逐渐实现了从“幕后参与者”到“共同引领者”的角色转型。这一转型既得益于全球治理理论在气候变化领域的延伸，更受惠于城市外交理论的推动和全球气候治理中“集体行动的困境”之驱使。就目前来看，中国城市的这一“共同引领者”角色还无法完全体现出来——不仅在隐性的“南北分割”的权力结构和发展中国家的气候治理分歧中，面临着对外发展的困境；而且在中央政府对地方政府的气候治理行动的“单向”型构造及城市的“经济发展”和“治理责任”的两难抉择中，面临着对内优化的瓶颈。针对这些问题，中国可以采取“两条干路+六条支路”的“两轨并行”式路径来寻求合理的应对之策。国家可以在寻求发展中国家的集体身份认同之时，进一步完善国内温室气体减排政策和立法，并赋予城市以一定的自主性；而城市也可以在深化城市气候外交，加强与国家的“双向”型气候治理互动的同时，推动“韧性城市”的长效发展。     

Family Therapy and the Pedagogy of the Oppressed: Therapeutic Use of Songs in Apartheid South Africa

A central issue for family therapy is the critical question of how to define its role in influencing social change. Family therapy has tended to focus on how to liberate and empower individual clients, not communities, from the travails of tradition. This article highlights social change mechanisms implemented by the oppressed majority in South Africa during the apartheid period. It draws inspiration from the pedagogy of the oppressed articulated by Steve Biko and other members of his generation. This enabled the Black majority in South Africa ‘to name their world by reflecting on their conditions, imagining a better world, and then taking action to create it’ (Freire, 1968, p. 253) through the use of revolutionary songs that resulted in the collapse of the cruel apartheid system. The implications for family therapy are discussed.     

Defining social work leadership: a theoretical and conceptual review and analysis

With the recent increase in social work leadership literature, a few issues in research and practice have come to light. Social work research employs leadership theory derived from military leadership principles adjusted for application in corporate entities, which have decidedly different goals and processes than social work organisations. These models may be influencing the methods of social work leadership research such that study outcomes reflect business-based rather than human service processes and goals. A dearth of leadership education in social work schools and in professional social work settings contributes to a paucity of social workers in upper level administrative roles. A systematic theoretical literature review on social work leadership is conducted in order to generate a working definition of social work leadership and a series of multi-level social work leadership principles. Implications for future research and practice are discussed.     

Tweeting about emergency: A semantic network analysis of government organizations’ social media messaging during Hurricane Harvey

While social media like Twitter have been increasingly adopted by public-sector organizations, it remains less explored as to how government and emergency management (EM) organizations use these platforms to communicate with the public in response to emerging natural disasters. Extending the Situational Crisis Communication Theory (SCCT) to the realm of social media, this study examines the emerging semantic networks from 67 government and EM organizations’ official tweets during Hurricane Harvey over a three-week period. It identifies how multiple crisis response strategies—including instructing information, adjusting information, and bolstering—are constituted of different issues, actions, and organizational actors before, during, and immediately after the disaster event. Results suggest that government agencies use the strategy of instructing information predominantly before and during the disaster, whereas adjusting information and bolstering strategies are utilized more during post-disaster recovery. The study offers theoretical and practical implications of using a semantic network approach to studying organizational crisis responses.     

中华民族共同体建设视阈下改土归流的历程、原因及作用

明清时期中央王朝实施的改土归流，不仅彻底废除了土司的政治、经济、军事、司法等特权，将国家版图内的人事权、财政权、军事指挥权、行政管理权、文化教育权等悉数收归中央，而且也是中华民族共同体由“自在”向“自觉”过渡的关键环节。明清改土归流经历了一个长期、艰巨、复杂的过程，其中既有土司利益与王朝利益的矛盾、各地土司与辖区民众的矛盾，也有中央王朝通过改土归流以增加税收、朝廷命官与乡村民众要求改土归流等现实动因。改土归流实现了国家“大一统”的目标、凸显明清国家治理能力的进步、加快了中华民族共同体建设的速度。中华民族共同体是一个由政治共同体、经济共同体、文化共同体和社会共同体四者构成的命运共同体。改土归流的实施，不仅是推动共同体由“自在”向“自觉”迈进的关键步骤和重要举措，而且使中华民族共同体在政治、经济、文化和社会诸方面发生巨大变化。
