For centuries, China’s farmers practiced agriculture in ways that sustained a high level of food production without depleting or deteriorating local resources. These were smallholder farmers, who came to be called peasants, or nongmin, in the early twentieth century. Narratives on the figure of the peasant have changed dramatically and often in the intervening years, expressing broader political debates, and suggesting the question, “what, then, is a Chinese peasant?” This paper attempts to answer that question in the context of reform (...) era China . Using a critical discourse analysis of nongmin in contemporary political and popular discourse, the paper aims to further clarify politics on the figure of the peasant in China today, specifically in relation to state policy on rural and agricultural development. The central argument is that in addition to complex meanings and uses of nongmin, a Chinese peasant is also a social category used by political and economic elites to stand in for the ills of China’s agrifood system, and to promote a model of development that tries to separate the country’s current trajectory from its long agrarian history. In the context of state-led agroindustrialization aimed at developing a robust domestic agribusiness sector, both peasants as a social form and smallholding as an agricultural form are targets for capitalist transformation. Put another way, political discourses define peasants and small-scale farming as China’s agrifood “problems” for which further capitalist industrialization is posed as the only and inevitable “solution.” The paper concludes by arguing that changing China’s current trajectory away from the crises of industrial agriculture will require also changing the discursive frame: it is agroindustrialization that is the problem, for which nongmin and China’s tradition of smallholder farming are part of the solution.

Employee counterproductive work behavior is costly to organizations and those who work within them. Evidence suggests that employees are motivated to engage in CWB because they believe that these behaviors will make them feel better in response to negative workplace events. However, research has yet to consider the situational and individual factors that shape the extent to which employees view CWB in such a manner. In order to provide insight into the decision-making process surrounding the use of CWB as a (...) coping strategy, this study leverages coping theory to examine the factors that contribute to employees’ beliefs that CWBs will be instrumental for emotion regulation aims in response to workplace stressors. In a repeated measures scenario-based study of 297 employees, we found that individuals’ perceived coping instrumentalities for CWBs are a function of the controllability and source of the stressor as well as a more stable learned response to stressful situations at work.

Warming temperatures in the circumpolar north have led to new discussions around climate-driven frontiers for agriculture. In this paper, we situate northern food systems in Canada within the corporate food regime and settler colonialism, and contend that an expansion of the conventional, industrial agriculture paradigm into the Canadian North would have significant socio-cultural and ecological consequences. We propose agroecology as an alternative framework uniquely accordant with northern contexts. In particular, we suggest that there are elements of agroecology that are already (...) being practiced in northern Indigenous communities as part of traditional hunter-gatherer food systems. We present a framework for agroecology in the North and discuss its components of environmental stewardship, economies, knowledge, social dimensions and governance using examples from the Dehcho region, Northwest Territories, Canada. Finally, we discuss several challenges and cautions in creating policy around agroecology in the North and encourage community-based research in developing and testing this framework moving forward.

Child liberationism holds that children are entitled to more freedom from interference than we currently acknowledge socially or legally. It holds, for example, that "the law [should] grant and guarantee to the young the freedom that it now grants to adults to make certain kinds of choices, do certain kinds of things, and accept certain kinds of responsibilities. This means in turn that the law [should] take action against anyone who interferes with young people's rights to do such things".1 Call (...) an agent minimally rational just in case he/she is capable of basic means-ends reasoning and of basic reflection on his/her beliefs and desires. No plausible form of child liberationism advocates full freedom from interference (i.e., as much as normal adults) for children that are not yet minimally rational. Some child liberationists do, however, advocate full freedom from interference for all minimally rational children -- typically those over age 5, say. Call this position radical child libera tionism . Other child liberationists only advocate full freedom from interference for older children -- typically those over age 12, say. Call this position moderate child libera tionism .2 For the sake of argument we shall grant that even young minimally rational children (e.g., 5 year olds) have full rights of non-interference. We shall argue that there are nonetheless a wide range of paternalistic practices regarding such children that are legitimate. In short, even granting the radical child liberationist thesis that young children have the same formal rights to freedom as competent adults, it does not follow that young children should enjoy the same effective freedom. Indeed, there are good reasons for holding that they should enjoy less freedom. Or so we shall.. (shrink)

_A passionate and moving tribute to the captivating power of dance, not just as an art form but as a language that transcends barriers__ “[A] smart, bracing book of reflection, analysis, memoir and history.”—Willard Spiegelman, ___Wall Street Journal___ “A veritable master class.”—Anne Doventry, _Booklist__ Mindy Aloff, a journalist, an essayist, and a dance critic, analyzes dance as the ultimate expression of human energy and feeling. From her personal anecdotes, her engaging collection of stories about dance from around the world, (...) or her description of the captivating photograph by Helen Levitt of two children dancing, which she sees as one embodiment of the mystery and joy that dancing can evoke, Aloff’s exploration of the aesthetic, social, and spiritual impacts of dance will prove spellbinding. Aloff takes us on a journey through various forms of dance—rituals, religious observances, storytelling, musical interpretations—to show why dance matters to human beings. Interlaced with personal experiences, this book builds on analysis to reveal the intimate relationship we have with dance—personal, spiritual, soul-searching, medicinal, and entertaining. The ideas speak to both specialist and general readers. (shrink)

Understanding of the λ model has greatly increased in recent years as evidenced by most of the commentaries. Some commentators underscored the potential of the model to integrate aspects of different sensorimotor systems in the production of movement. Other commentators focused on not-yet-fully-developed parts of the model. A few persisted in misunderstanding some of its basic concepts, and on these grounds they reject it. In responding to commentaries we continue to elaborate on some fundamental points of the model, especially control (...) variables, the idea of movement production by shifting the positional frame of reference and the hypothesis of biomechanical correspondence in motor control. We also continue to develop our ideas on the intrinsic generation of the frame of reference associated with external space and utilized for the control of arm movement and locomotion. The dynamic principles underlying the model are discussed in light of the dynamical systems approach. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:“Just Because You Can—Doesn’t Mean You Should”Mindy B. StatterAs Albert R. Jonsen stated, “The technological imperative begins to rule clinical decisions: if a technology exists, it must be applied. Patients... are moved to higher and higher levels of care, finally becoming enmeshed in a tangle of tubes that extinguish their identity and needs as persons.” In this case the conflict created by the parental demand for the utilization (...) of technology, extracorporeal support in a neonate will be explored.I was consulted in the care of a newborn with a right–sided congenital diaphragmatic hernia (CDH). In this anomaly the diaphragm, the muscular partition that separates the abdomen and the thorax, forms incompletely, and the viscera migrate up into the chest compressing the developing lung, shifting the medistinum and heart and compressing the contralateral lung. The resulting lung maldevelopment is termed pulmonary hypoplasia. The maldevelopment of the lungs in CDH is variable with the most severe forms resulting in neonatal death. This congenital anomaly is associated with 55% survivability; the poor prognosis is due to the pulmonary hypoplasia. In addition to pulmonary hypoplasia, there is the association of pulmonary hypertension with CDH. Pulmonary hypertension is a condition where the vascular resistance in the lung is high with reduced blood flow within the lung. The physiologic consequence of pulmonary hypertension is hypoxemia, oxygen deficiency in the blood, and reduced oxygen delivery to all organs. Unlike severe pulmonary hypoplasia, pulmonary hypertension is reversible. When an infant with CDH is born and deteriorates due to respiratory failure it can be difficult to determine whether the respiratory failiure is due to pulmonary hypoplasia or pulmonary hypertension. Extracorporeal membrane oxygenation (ECMO) is indicated in the management of reversible respiratory and, or cardiac failure. In the case of neonates with CDH, ECMO addressess the reversible component of the respiratory failure, the pulmonary hypertension. The respiratory failure due to severe pulmonary hypoplasia is not reversible; ECMO is not indicated. There are established criteria to guide the determination of which infant is a candidate for ECMO. Depending upon the ECMO center, the stringency can vary.In this case, the baby had significant respiratory failure with impairment in both oxygenation, hypoxia, and ventilation–the elimination of carbon dioxide, hypercapnea. The neonatologist spoke with the mother who stated that she wanted “everything done” including ECMO in the management [End Page 22] of her baby. When the neonatologist consulted me to put the baby on ECMO I expressed my concern that this infant had irreversible respiratory failure due to pulmonary hypoplasia. And simply from a technical aspect, I could not guarantee that ECMO would “work”. When an infant is “cannulated” for extracorporeal support, cannulas are inserted to allow for the drainage of blood into the ECMO circuit, the blood oxygenated and the carbon dioxide is cleared, and the blood is then returned to the infant. The majority of diaphragmatic hernias are on the left and when the CDH is on the right side, the right heart may be compressed by the viscera in the chest, and venous drainage into the ECMO circuit may be impaired. When this is encountered, the next step in the management algorithm is to fix the hernia–reduce and return the viscera within the chest to the abdomen and eliminate the visceral compression of the right heart. The neonatologist shared my concern and also reiterated that this baby’s mother wanted “everything done”. I had little uncertainty as to the etiology of the respiratory failure in this baby. In meeting the mother’s demands I then suggested that the hernia be repaired first, and if there was improvement in the hypoxia and hypercapnea, then give the baby the benefit of the doubt that there is a component of reversibility to the respiratory failure and then proceed with ECMO cannulation. The neonatologist agreed with this suggested plan.I then went to talk with the baby’s mother. I explained my concerns that based on the profound hypercapnea on the arterial blood gases that the baby’s respiratory failure was due to pulmonary hypoplasia and not reversible with extracorporeal support. She insisted that her baby be put on ECMO. I then explained the operative algorithm and... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Bodily Arts: Rhetoric and Athletics in Ancient GreeceMindy FenskeBodily Arts: Rhetoric and Athletics in Ancient Greece by Debra Hawhee. Austin: University of Texas Press, 2004. Pp. xiv + 226. $40.00, hardcover.In Bodily Arts, Debra Hawhee constructs an often compelling, always interesting case for the conceptual and material linkages between the ancient arts of rhetoric and athletics. In so doing, Hawhee also highlights the integral role of the musical (...) arts to rhetorical and athletic training. Throughout the book, Hawhee weaves together close readings of multiple texts (poetry, oratory, sculpture, painting, architecture) in order to illuminate the intricate “network of overlapping practices” that connect the bodies of rhetoric, athletes, and musicians in Ancient Greece. To this reader, the central strengths of the study are methodological as well as conceptual. In terms of method, Hawhee carefully and with studied finesse integrates close readings of visual, spatial, and verbal texts and practices. In the wrong hands, this type of endeavor can easily appear as the worst kind of pastiche. Not so in this case where Hawhee manages the textual interpretation with deft expertise. Conceptually, the central premise that rhetoric was a practice that was fully embodied and, most importantly, that embodiment was not in a hierarchical relation to reason, rationality, and the mind is provocative. Hawhee argues that the relations of mind-body in Ancient Greek culture were understood as a complex interlocking system that, when trained through physical practices emphasizing rhythm, repetition, and response (to/with an encounter), resulted in the possible transformation of the very nature of the self. [End Page 197]In the process of constructing the argument for the connections between rhetorical and athletic training and performance, Bodily Arts moves through three phases. The Introduction and first three chapters lay the theoretical groundwork for the second phase: the introduction of the concept of phusiopoieses in Chapter 4. Chapters 5–7 then discuss the actual rhetorical and athletic spaces, practices, and bodies of and in phusiopoiesis.The introduction opens with description of a first-century BC bronze statue of an “Antikythera Youth” (3). Hawhee uses the mystery surrounding the identity of the figure (deciphered largely through interpretations of the actions implied by the stature of the statue) to articulate the connections between the body of the rhetor and the body of the athlete as well as to introduce the importance of the body to Greek values of hexis (comportment) and aretē (virtuosity). The Introduction also presents three critical relations that serve both as conceptual departure points as well as hail the multiple audiences of the book: relations of body and mind, learning and performing, and classical studies and rhetorical studies. Hawhee’s perspective is quite straightforwardly that rhetoric is an art that required physical training and physical performance.Chapter 1, “Contesting Virtuosity: Agonism and the Production of Aretē,” connects the values of agon and aretē and argues that the “very logic for linking rhetoric and athletics” lies at the heart of this relation (22). Hawhee argues that agon and aretē are less about ends (victory and virtue) and more centrally concerned with embodied processes. Agon, through Hawhee’s reading of Hesiod’s Work and Days, is articulated as a mode of encounter that produces a particular, and possibly transformative, response. Aretē is the bodily performance of virtuosity. Central to this performance, according to Hawhee’s interpretation of the Olympic ethos through Pindar’s poetry, is the activity of questing. Aretē is demonstrated rather than simply won or attained. Following these definitions of agon and aretē, the chapter moves to illustrating the shared language of rhetoric and athletics in terms of these values. Hawhee argues that this shared vocabulary confirms that sophistic rhetoric was understood and practiced as an embodied and agonistic art “fused and infused” with athletics (43).In Chapter 2, “Sophistic Mētis : An Intelligence of the Body,” Hawhee describes mētis as cunning and somatic becoming that “infuses the arts of rhetoric and athletics with a kind of bodily intelligence... not an explicit set of precepts but rather a tacit style of movement running through most kinds of actions, including thought” (47). Moreover, the movement of mētis [End Page 198] is corporeal. It... (shrink)

The common law's approach in the law of unjust enrichment is to enumerate specific «unjust factors» as permissible causes of action in claims for restitution. This approach has come under attack, inter alia, for being unnecessarily complicated. The claim is that the civilian approach, with its single ground of absence of legal cause for the transfer, is preferable since the operative unjust factor in any particular case is irrelevant to the restitutionary response. In defence of the common law's approach, this (...) article tenders four aspects of the restitutionary response which, it is claimed, are illuminated by reference to the nature, context, and effect of the operative unjust factor in any particular case. They are: (i) the availability of the defence of change of position; (ii) the justifiability of certain «bars» on rescission and the permissible mode of mutual restitution on rescission; (iii) the appropriate measure of enrichment where restitution is, or must be, effected in money; and (iv) two possible justifications for the controversial remedy of partial rescission.

Fraternity little sister organizations are a relatively unexplored aspect of the contemporary college campus culture. This article examines the construction of the collective sexual reputation of fraternity little sisters and how fraternity little sisters interpret and resist it in an effort to maintain their individual sexual reputations.

The United States has pursued policies of urban upheaval that have undermined social organization, dispersed people, particularly African Americans, and increased rates of disease and disorder. Healthcare institutions have been, and can be, a part of this problem or a part of the solution. This essay addresses two tools that healthcare providers can use to repair the urban ecosystem—perspective and solidarity. Perspective addresses both our ability to envision solutions and our ability to see in the space in which we move. (...) Solidarity is our ability to appreciate our fellowship with other people, a mindset that is at the heart of medical practice. These two tools lay the foundation for structurally competent healthcare providers to act in a restorative manner to create a health-giving built environment. (shrink)

A hypothesis about sensorimotor integration (the λ model) is described and applied to movement control and kinesthesia. The central idea is that the nervous system organizes positional frames of reference for the sensorimotor apparatus and produces active movements by shifting the frames in terms of spatial coordinates. Kinematic and electromyographic patterns are not programmed, but emerge from the dynamic interaction among the system s components, including external forces within the designated frame of reference. Motoneuronal threshold properties and proprioceptive inputs to (...) motoneurons may be cardinal components of the physiological mechanism that produces positional frames of reference. The hypothesis that intentional movements are produced by shifting the frame of reference is extended to multi-muscle and multi-degrees-of-freedom systems with a solution of the redundancy problem that allows the control of a joint alone or in combination with other joints to produce any desired limb configuration and movement trajectory. The model also implies that for each motor behavior, the nervous system uses a strategy that minimizes the number of changeable control variables and keeps the parameters of these changes invariant. Examples are provided of simulated kinematic and electromyographic signals from single- and multi-joint arm movements produced by suggested patterns of control variables. Empirical support is provided and additional tests of the model are suggested. The model is contrasted with others based on the ideas of programming of motoneuronal activity, muscle forces, stiffness, or movement kinematics. (shrink)

This article examines gay men’s efforts to break into the exclusive traditional fraternity institution by adopting the hegemonic model on their own terms. The authors examined to what extent members of a national gay fraternity, Delta Lambda Phi challenged or modified the entrenched fraternity culture that was hostile to homosexuals and whether they resisted or reproduced hegemonic masculinity in their efforts to redefine the meaning of college fraternities. This research examines gay fraternities in relation to two dimensions of hegemonic masculinity. (...) The authors explore how members of gay fraternities negotiated their stigmatized status among other men—that is, within the internal dimension of hegemonic masculinity. They explore the external dimension of hegemonic masculinity by analyzing how gay brothers, as men, related to all women. The authors further examine the connection between these two hegemonic dimensions and provide evidence showing how these two dimensions are coupled or disjointed. (shrink)

IBERTARIANS hold that we have such duties as: not to directly and significantly harm others or their property, to keep agreements, to refrain from lying and certain other sorts of deception, and to compensate those whom we wrong. They also hold that we have a duty not to interfere with the liberty of others as long as they are fulfilling these duties. This duty of non-interference, they have thought, has protected the privacy of the home, and hence parental autonomy, for (...) it insures that others have no authority over or responsibility for (except in extreme circumstances) how parents raise or treat their children. (Why parental autonomy has been held to be protected by this duty of non—in_terference should be clear enough: for if (as is surely plausible) the main effect of that duty is to secure for adults the liberty (within limits) to live their private lives as they choose, then, on the natural assumption that the matter of how to raise one`s children falls within the domain of the private lives of adults, intervention by others, and in particular by the state, for the purpose of ensuring that children get raised in one way rather than another, would be impermissible.) More specifically to our purposes now, libertarians have supposed that the duty of non-interference leaves intact parents` perogative to decide if, and in what way, their children are to be educated. That this is crucial both to the degree and to the point of parental autonomy is clear enough. For it goes both to the matter of keeping out of the private home those who would provide education for children (if such is the wish of the parents), and to the matter of parents` entitlement to instill in their children the values that they (the parents) wish their children to have. Libertarians, however, have not had very much specific to say about the moral status of children. Are children owned by their parents? Do they have all the rights and duties that normal adults have'? Or is their status somewhere in between these extremes? Given that libertarians haven't said, there are different possible ways of extending traditional libertarian theory so as to cover children..

This study highlights a range of perspectives offered by 11 international teachers, participating in a cultural immersion experience, as they reflect on how they saw democracy manifested at their school internships. Teachers from six different countries studied and taught in a rural community in the Southern United States, where a medium-sized research university hosted the teachers as part of a federally-funded program during an academic semester. As a part of a larger qualitative research study analyzing the international teachers’ perception of (...) American schooling, data from intercultural sessions, individual interviews, and assigned reaction papers highlighted multiple contradictions between the teachers’ interpretation of democratic ideals and democratic education as they saw manifested in American schools. These narratives highlight the complex forces that shape individuals’ perceptions of democracy as played out in the everyday life of a cultural immersion experience. The researchers suggest that these transnational perspectives can serve as a mechanism allowing Western educators to listen to the “Other” as they interrogate taken-for-granted assumptions about American schooling. Narratives primarily highlight inconsistencies between the goals of citizenship education and the way in which citizenship is promoted or neglected in K-12 classrooms. (shrink)

Suppose that in the Meditations Descartes thinks he needs to prove that his clear and distinct perceptions are true. There can be little doubt that if he does think he needs to do this, he thinks that the way to do it is to prove that ‘a non-deceiving God exists’ is true. Now suppose that Descartes does come up with such a proof. Presumably he clearly and distinctly perceives both the premisses and that ‘a non-deceiving God exists’ follows from them. (...) But that will not suffice to prove that ‘a non-deceiving God exists’ is true. For, if there is a problem about whether clear and distinct perceptions are true, then in advance of settling it, there is a problem about whether what is proved merely on the basis of clear and distinct perceptions is true.

The cerebellum probably obeys the rules of sensorimotor integration common in the nervous system. One such a rule is formulated: the nervous system organizes spatial frames of reference for the sensorimotor apparatus and produces voluntary movements by shifting their origin points. We give examples of spatial frames of reference for different single- and multi-joint movements including locomotion and also illustrate that the process of motor development and learning may depend critically on the formation of appropriate frames of reference and the (...) organism's ability to manage them. We suggest that a solution to the problem of sensorimotor integration may not be trivial and may actually change the mental and experimental paradigms used in the understanding of the cerebellum and other brain structures, [HOUK et al.; SIMPSON et al.; SMITH; TIIACH].

Perceived discrimination has consistently been shown to be associated with diminished mental health, but the psychological processes underlying this link are less well understood. The present series of four studies assessed the role of a history traumatic events in generating a proliferation of discrimination stressors and threat appraisals, which in turn predict psychological distress (depressive and posttraumatic stress symptoms) (mediation model), or whether prior traumatic events sensitize group members, such that when they encounter discrimination, the link to stress-related symptoms is (...) heightened (moderation model). Each of the studies assessed a different marginalized group in Canada, including Indigenous peoples, Blacks, Jews, and a diverse sample of women. Participants completed measures assessing history of traumatic events, perceived explicit and ambiguous discrimination, discrimination threat appraisals, and symptoms of depression and posttraumatic stress. The four populations varied in their experiences, with Indigenous peoples encountering the highest levels of trauma, discrimination, and psychological distress symptoms. A mediated model was evident among Indigenous peoples and women, possibly reflecting the role of systemic processes that engender discrimination when traumatic events are experienced. There was evidence for a moderating role of a history of traumatic events on the relations between discrimination and depressive symptoms among Jewish and Black participants. Although the hypothesized synergistic effects of traumatic experiences were noted when assessing the relation between perceived discrimination and depressive symptoms among Jews, the presence of trauma blunted these relations among Blacks. The results suggest that trauma-informed approaches to addressing stress-related processes and psychological outcomes need to consider the unique social context of members of various socially marginalized groups.
