Preparation of acetate peels of valves from the ocean quahog, Arctica islandica, for age determinations

Techniques are described for preparing acetate peels of sectioned valves of ocean quahogs, Arctica islandica, for age determinations. The respective sequence of preparation begins by sectioning left valves oriented to include a single hinge tooth, bleaching to remove the heavy periostracum, embedding the valves in an epoxy resin, grinding and polishing the embedments to a high luster, etching the exposed cut valve surfaces, and applying sheet acetate with acetone. Annuli are clearly defined relative to growth increments in the peel preparations for all sizes and ages of ocean quahogs. (PDF file contains12 pages.

My Struggle with a Ten-Square

The genesis of the work described herein was a conversation with Murray Parce (\u27Merlin\u27, in the National Puzzlers\u27 League) at the Carlottesville convention in July 1987. We agreed on collaborative efforts to construct a nine-squre, something no NPL member had done for an umber of years. The first result appeared in the December 1987 issue of the Enigma: a nine-square by him based on STEERLESS, and one by me on TERSENESS

Further Struggles With A Ten-Square

In the May 1988 Word Ways I described my struggle to construct a non-tautonymic ten-square -- with less than stellar results. Since that time, I have collaborated with Eric Albert of Auburndale, Massachusetts, who has programmed his PC to search for useful combination of the three or four bottom words. By useful combinations, I mean that these words are chosen to generate plausible ending such as -ENCE, -ING, -TION, etc., for all ten proposed words of the square

The Elusive Ten-Square

Hats off to Jeff Grant! In 9x9 Word Squares in the November, 1980 issue of Word Ways, he has rescued the nine-square from near-oblivion and done so within the confines of dictionaries. His article rekindled the spark of an old interest of mine -- the ten-square. For some time, I have felt (as Jeff Grant does) that constructing a ten-square is not beyond the realm of possibility

Interconnections Between Perceptions of Blame, Mind, and Moral Abilities

Theories of blame, mind, and moral attribution consider an individual’s perceived agency, operationalized in part as perceived intentionality and self-control. People with autism spectrum disorder (ASD) may display social deficits and a greater tendency to engage in problem behavior (PB; American Psychiatric Association, 2013) than neurotypical (NT) people, which may lead people to perceive that individuals with ASD act less agentically. Study 1 shows that the mitigated perceived agency of people with ASD leads to mitigated blame attribution. In addition to perceived agency, theories of mind and moral attribution account for perceptions of an individual’s capacity to experience emotions, pleasure, and suffering. Based upon these forms of perception, Gray et al.’s (2007) theory of mind perception (TMP) states that minds are perceived along the dimensions of agency and experience. Similarly, Gray, Young, and Waytz’s (2012) theory of dyadic morality (TDM) states that a person’s moral status is perceived along the dimensions of moral agency and patiency. While these dimensional pairs are highly similar, the TMP states that its proposed dimensions are independent of each other while the TDM states that its proposed dimensions are inversely related. Studies 2 and 3 generated support for the prediction that these dimensions are independently related, as proposed by TMP, while the inverse relationship posited by the TDM did not receive support

Do Network Management and Trust Matter for Network Outcomes? A Meta-analysis and Research Agenda

Collaborative and network governance assume that network management and trust matter for network outcomes. We test this assumption by conducting a meta-analysis of public administration studies investigating the correlation between network management and network outcomes (50 effect sizes), and trust and network outcomes (28 effect sizes). While both matter for achieving network outcomes across countries, trust matters most. Trust is particularly important for achieving process outcomes and multiple network management strategies combined are more effective than separate single strategies. A research agenda centred on complex modelling, comparative research and using mixed, multisource, experimental and longitudinal data is stipulated in conclusion
