Disjunctive Quantum Logic in Dynamic Perspective

In Coecke (2002) we proposed the intuitionistic or disjunctive representation of quantum logic, i.e., a representation of the property lattice of physical systems as a complete Heyting algebra of logical propositions on these properties, where this complete Heyting algebra goes equipped with an additional operation, the operational resolution, which identifies the properties within the logic of propositions. This representation has an important application towards dynamic quantum logic, namely in describing the temporal indeterministic propagation of actual properties of physical systems. This paper can as such by conceived as an addendum to Quantum Logic in Intuitionistic Perspective that discusses spin-off and thus provides an additional motivation. We derive a quantaloidal semantics for dynamic disjunctive quantum logic and illustrate it for the particular case of a perfect (quantum) measurement.     

Choosing the Appropriate Design and Analysis of a Research Project

It is extremely important that the proper mental planning of a research project is considered before the data collection ever begins. Otherwise, problems may be encountered after the data have been collected and it may then be too late to correct them. This paper will explain some of the important considerations necessary in choosing an adequate design and analysis for a research project.     

The Kawa River Model: Applying Theory to Develop Interventions for Combat and Operational Stress Control

This article proposes the implementation of the occupational therapy Kawa (Japanese for river) model to promote “culturally relevant” client-centered care for combat and operational stress control services provided in the military context. Currently, the occupational therapy literature lacks a culturally sensitive approach to address the military service members’ experiences with combat and operational stress. A review of the Kawa model features are provided within a case study for a military service member affected by combat and operational stress. This theoretical article offers a pragmatic method for infusing occupational therapy theory to address the cultural aspects of military service members in recovery.     

Perceived Occupational Concerns and Sensory Processing Patterns of Mothers in a Temporary Assistance for Needy Families (TANF)-to-Work Program

In this study, the authors examine the perceived occupational concerns, typical daily routines, and sensory processing of mothers in a mandatory Temporary Assistance for Needy Families return to work program. Participants were five female members of a transitional work program for single parents with mental illness. The Canadian Occupational Performance Measure and the Adult Sensory Profile were administered. The study found that the most frequently identified occupational problems were leisure and self-care. All participants scored as having at least one atypical sensory processing pattern. Future research should investigate the efficacy of an occupational therapy intervention on this population's return to employment.     

Thermal stability of nanocrystalline fcc and hcp Ni(Si) synthesized by mechanical alloying of Ni90Si10

The thermal stability of nanocrystalline fcc and hcp Ni(Si), obtained by mechanical alloying of Ni₉₀Si₁₀, has been studied. The allotropic transformation from fcc to hcp Ni(Si) is accompanied by a volume expansion of 8.6% and is observed when fcc Ni(Si) reaches a critical crystallite size of 10nm. The hcp phase transforms to stable fcc Ni(Si) at 573K. It has been identified that the lattice distortion in nanometre-sized crystallites from the equilibrium configuration and the decrease in the interfacial energy with grain refinement act as self obstacles in controlling the grain growth of nanocrystalline materials.     

HREM examination of [101] screw dislocations in Ni3Al

Abstract

The dissociation of [101] screw dislocations in Ni³Al has been examined using high-resolution electron microscopy. [101] superdislocations are found to be dissociated into (a/2)[101] superpartial dislocations on the (010) cube cross-slip plane. These superpartials in turn dissociate into complex stacking faults on the (111) or (111) which are bounded by Shockley partials in agreement with theoretical predictions. The degree of antiphase boundary spreading on (010) was found to increase with deformation temperature while the superpartial core dissociations remain unchanged.     

Chile's Environmental Assessments: Contested Knowledge in an Emerging Democracy

Abstract

In 1990, Chile transitioned to democracy after 17 years of military rule. The new democracy built the country's first environmental institutions and began efforts to revitalize science, among them attempts to connect scientific expertise to public decision-making. Just over a decade into these efforts, conflicts over the environmental impacts of large industrial projects began to multiply. These environmental conflicts were often also credibility contests, where the authority of science to speak to public issues was contested. Two such conflicts, a gold mine called Pascua Lama and a hydroelectric project called HidroAysén, enrolled several scientific teams, yet in each case the state made its final decision on each project autonomously from science. Though some scientists became central participants in each conflict, carving out for themselves access to needed resources that they used to practice ever-narrower forms of science, their credibility was called into question by many of their scientific colleagues. Chile's scientific community fractured over how to define credible science. Divisive and decisive issues included the source of funding, ethics, access to resources, and being local. Although some scientists and non-scientists used boundary work to try to affirm the authority of science, no stable map of scientific credibility resulted from these efforts. Chile's new democracy is more plural than its recent military dictatorship but still lacks adequate spaces in which to negotiate what counts as credible science. These experiences highlight the need to better understand how science fares through regime transitions and what it contributes to emerging democracies.     

Accountability from Somewhere and for Someone: Relating with Care

Abstract

In contemporary care institutions, accountability procedures and devices are increasingly pervasive and considered crucial for monitoring quality. Such accountability practices are based on the idea that accountability and care belong in two separate domains. The distinction between accountability ‘from nowhere and for everyone’ and accountability ‘from somewhere and for someone’ problematises this implicit split. Taking seriously the observations of everyday caring and accounting by care professionals, who resist splitting care and accountability from the outset, demands a reconceptualisation of the relation between care and accountability as reciprocal and co-emerging. Both accountability and care are highly circumstantial, emerging, relational notions and it is not clear-cut who or what cares or accounts for what, whom, where and how. Paying due attention to the generative interweaving of accounting and caring, that is, to the narrative work of care professionals, affords the potential to turn universal abstract norms of what good care should be into meaningful care. Creatively reconnecting care experiences, observations, records and relations generates accountability with care. Care professionals do this by daring to prioritise speculatively what matters most in a specific situation without falling back on the reassurance of clear-cut norms of good care and by daring to admit that even while prioritising a certain course of action, they might not know its consequences. Such a speculative commitment and the inclusion of the researcher's experiences in trying to be accountable are crucial for studying accountability as a matter of care and as relatedness in the making.     

Tensions of Accountability: Scientists,Technicians and the Ethical Life of Data Production in Astronomy

ABSTRACT

Laboratory ethnographies have emphasized the importance of trust and accountability among scientists and technicians when working in co-presence. But what happens to their relations when data production is outsourced, widely separating scientists and technicians? In contemporary astronomy, observing has largely become a service that observatory staff members do for researchers. This has increased the efficiency of telescope use while also resulting in arrangements prone to some researchers’ dissatisfaction and a raised visibility of technicians’ work. Attending ethnographically to situated evaluations reveals that some data-using researchers and data-producing technicians typify each other as moral figures: staff observers come to be seen as objects of blame and scientists as excessively demanding users. Wherever data travel, the quality and quantity of data can serve as ethical affordances for assigning blame to staff technicians. By contrast, the moral figure of the excessively demanding data user does not travel beyond the observatory, and the social accountability of interactions that visiting astronomers experience in the observatory’s control room is confined to its situated enactment. As scientist–technician interactions have become discontinuous and fraught, moral figures and ethical accounts thus travel unevenly in the landscape of data production, and the importance of social interactions remains often unrecognized.     

Towards new work arrangements: The case of telecommuting

Telecommuting is an example of novel ways of organizing work now being implemented in technologically advanced nations. It is the major industrialized countries that have provided the circumstances and the incentives to experiment with new approaches. These approaches were created within, and co‐exist with these models of social organization. They also embrace some elements that undermine basic tenets of industrial models. Telecommuting is discussed below as an example of newly evolving work arrangements which illustrates the interplay of tensions between existing models of work organization and innovative ways of ordering tasks. This paper is based upon graduate research in Rural Extension. The conceptual framework was created by synthesizing material from interdisciplinary sources and primary data collection included in‐depth interviews with key informants engaged in telecommuting.
