女性"隐形"地位的多元认知透视

在男性占主导地位的语言,诚如英汉语中"乞丐""医生"等职业术语和"chairman""hero"等官衔荣誉称呼之类的名词,一般性的人类泛指"a man","mankind"以及代词的非指示用法中,女性往往被置于"隐形"的地位。性别差异和性别歧视的现象已引起社会上各学科的普遍关注,然而,从认知角度对这一现象作出注解的文章寥寥。运用认知语言学中的原型和范畴理论、框架理论、心理空间和概念合成理论对此予以阐释,可为英汉语中这一现象的理论阐释提供全新的多元认知视角。     

南唐经济发展原因及其相对性探要

南唐是五代十国时期南方国家中与中原抗衡的中坚力量， 其经济发展取得了很大成就。统治者施行保境息民政策、实施阻断北方割据势力南渐的策略 以及唐代江淮地区经济发展的基础等，是经济得以恢复和发展的重要原因；而与邻邦之间的 长期战争、小生产模式下沉重的封建剥削和日益激化的派系斗争，则使南唐的经济发展仍未 达到理想的水平。探索南唐经济发展的原因及其相对性，具有重要的历史和现实意义。

Communicating Conservation Status: How Different Statistical Assessment Criteria Affect Perceptions of Extinction Risk

Although alternative forms of statistical and verbal information are routinely used to convey species’ extinction risk to policymakers and the public, little is known about their effects on audience information processing and risk perceptions. To address this gap in literature, we report on an experiment that was designed to explore how perceptions of extinction risk differ as a function of five different assessment benchmarks (Criteria A–E) used by scientists to classify species within IUCN Red List risk levels (e.g., Critically Endangered, Vulnerable), as well as the role of key individual differences in these effects (e.g., rational and experiential thinking styles, environmental concern). Despite their normative equivalence within the IUCN classification system, results revealed divergent effects of specific assessment criteria: on average, describing extinction risk in terms of proportional population decline over time (Criterion A) and number of remaining individuals (Criterion D) evoked the highest level of perceived risk, whereas the single‐event probability of a species becoming extinct (Criterion E) engendered the least perceived risk. Furthermore, participants scoring high in rationality (analytic thinking) were less prone to exhibit these biases compared to those low in rationality. Our findings suggest that despite their equivalence in the eyes of scientific experts, IUCN criteria are indeed capable of engendering different levels of risk perception among lay audiences, effects that carry direct and important implications for those tasked with communicating about conservation status to diverse publics.     

Piety over Protest: Cognitive Liberation and Deflected Collective Action in Central India

Cognitive liberation is often treated in the social movements literature as a mediating factor through which political opportunities and mobilizing structures generate protest. This paper unpacks multiple dimensions of cognitive liberation and finds that they may operate in tension with one another. Building on scholarship that focuses on subjective factors in social movements, the paper examines the case of the Korku, an oppressed indigenous community in central India, who choose not to protest despite the presence of several dimensions of cognitive liberation. Rather than engage in collective political action, the Korku’s grievances are deflected toward depoliticized religious goals. The Korku seek communal improvement through Hindu piety in a context of the Hindutva cultural-nationalist ideology, rather than protest against the encroachment of this ideology on their community.     

Managing C-suite conflict: The unique impact of internal and external governance interfaces on top management team reflexivity

The ability of Top Management Teams (TMTs) to reflect critically on their own actions represents an important element of effective TMT decision making and governance effectiveness. This paper therefore examines how the TMT-board interface internal to the organization, as well as the TMT interface with the external supervisory authority, shape TMT reflexivity. Drawing from governance and psychological theories, we posit that cognitive conflict at the TMT-board interface can escalate by increasing levels of affective TMT-board conflict, and hereby, harm TMT reflexivity if not managed well. This proposition was tested in a multisource team-level data set collected in the field among TMTs (N = 111 TMT members) and their supervisory boards (N = 152 board members) of 56 Dutch insurance companies. The findings demonstrate that the link between cognitive and affective TMT-board conflict is mitigated by board membership influx. Yet in cases where conflict escalation does occur, its subsequent impact on TMT reflexivity hinges on the degree to which an external supervisory authority monitored TMT actions. The results illustrate that TMT decision making processes can be effectively influenced by internal and external TMT-governance interfaces, yet at different conflict stages, and through different governance actions.     

The effect of cognitive diversity on the illusion of control bias in strategic decisions: An experimental investigation

By integrating cognitive diversity into debiasing literature, this paper contributes towards opening the black box of executive judgment. Based on information processing theory we investigate the role of cognitive diversity in strategic decision making. We apply a vignette-based experimental research design to examine the effect of cognitive diversity in teams on decision maker's illusion of control. The results of these experiments provide evidence for a positive influence of high cognitive diversity for debiasing judgment while similarly indicating no such effect for groups with low cognitive diversity. These findings suggest that group composition aspects can play an important role for improving judgment in decision making teams and open promising new avenues for studying debiasing in behavioral strategy research.     

Prevalence of Elder Mistreatment as Reported by Social Workers in a Probability Sample of Adult Day Health Care Clients

ABSTRACT

There are growing numbers of Adult Day Health Care (ADHC) programs providing needed health services to community-dwelling elderly. Therefore, ADHC staff are in an opportune position to identify and to intervene in suspected elder mistreatment (EM) cases. In this paper, prevalence estimates of EM are reported for a probability sample of ADHC clients in New York State, using data provided during a social worker informant interview. The abuse “signs and symptoms” items in the social worker informant interview schedule were divided into two categories: (1) physical indicators and (2) client's behavioral indicators. Physical indicators included unexplained bruises and welts, unexplained burns, unexplained lacerations or abrasions, human bite marks, and frequent injuries that are “accidental” or “unexplained.” Client's behavioral indicators included apprehension, being frightened, and afraid to go home. EM prevalence for all 8 items was 12.3 percent. When “apprehensive” was excluded, the EM prevalence was 3.6 percent in this sample. These findings suggest that ADHC provides a point of contact for the assessment and intervention of EM that might otherwise be overlooked among elders who are often isolated or homebound.     

Throughput and delay analysis of an opportunistic tree algorithm

Tree algorithms are a well-known class of random access algorithms with a provable maximum stable throughput under the infinite population model (as opposed to ALOHA or the binary exponential backoff algorithm). In this article, we propose a tree algorithm for opportunistic spectrum usage in cognitive radio networks. A channel in such a network is shared among so-called primary and secondary users, where the secondary users are allowed to use the channel only if there is no primary user activity. The tree algorithm designed in this article can be used by the secondary users to share the channel capacity left by the primary users.

We analyze the maximum stable throughput and mean packet delay of the secondary users by developing a tree structured Quasi-Birth Death Markov chain under the assumption that the primary user activity can be modeled by means of a finite state Markov chain and that packets lengths follow a discrete phase-type distribution.

Numerical experiments provide insight on the effect of various system parameters and indicate that the proposed algorithm is able to make good use of the bandwidth left by the primary users.
