Interview with Tom Bertocci by Mike Hastings
Biographical NoteTom Bertocci was born in Lewiston, Maine, on February 17, 1945. His father was Salvatore Theodore “Ted” Bertocci, the son of Italian immigrants who came to the United States in 1912. Two of Tom’s uncles became professors at Bates College, where they met Ed Muskie. Tom’s father worked at Bath Iron Works, and met Tom’s mother, Margaret True Allen of Auburn, Maine, through his brothers. Tom was graduated from Morse High School and Wesleyan University. He became involved with the Chewonki Foundation during his college years, when he worked there as a camp counselor. He taught history at the Hotchkiss School in Connecticut, then earned a masters degree in education at the University of Wisconsin while becoming increasing interested in activism and politics. He became the first director of the Chewonki Foundation’s Maine Reach School, where he led a citizen action project with students to help on George Mitchell’s 1974 campaign for governor. He returned to Wisconsin as a full-time graduate assistant and co-authored Skills in Citizen Action with Fred Newman. In 1979, he returned to Maine to work for the Maine Audubon Society’s campaign opposing repeal of Maine’s bottle bill. In the spring of 1980, he was hired as a field representative and driver in Mitchell’s Rockland, Maine, field office, where he remained until Mitchell retired in 1995. He married his wife, Portland native Cindy Stanhope, in 1981. He died on April 4, 2010, at his home after a prolonged illness.

The amphipod assemblages of Sabellaria alveolata reefs from the NW coast of Portugal: An account of the present knowledge, new records, and some biogeographic considerations
Amphipod assemblages associated with the biogenic reefs built by the honeycomb worm Sabellaria alveolata were studied at two sites (Praia da Aguda and Belinho) along the northwestern coast of Portugal. A total of 3909 specimens were collected, comprising 14 different amphipod species. A first record from the northeastern Atlantic coast was registered here for the species Caprella santosrosai, which was, up to now, recorded only along the Mediterranean coast of the Iberian Peninsula. A male specimen collected from the Sabellaria-reef located in Belinho allowed an update to the known distribution of C. santosrosai, thus altering its previous status as an endemic Mediterranean species. The most common species collected during the study were Microdeutopus chelifer (n = 1828), Jassa ocia (n = 1426), and Hyale stebbingi (n = 452). Forty-three percent of the total recorded species were encountered in both study sites, whereas the remaining 57 % were restricted to a single site (Belinho). The majority of the collected species (93 %) showed an Atlantic-Mediterranean distribution, confirming the close affinity between eastern Atlantic and Mediterranean amphipod assemblages and the role of the Portuguese coast as a transition zone through which numerous warm-water species, coming from North Africa and the Mediterranean Sea, could enter into the Atlantic and possibly get mixed with species coming from the North Sea and the Arctic, typically having affinity for colder waters
MEDIA USE BY CHILDREN AND ADOLESCENTS WITH AND WITHOUT DEPRESSION: GOING IT ALONE?
Using experience sampling methodology this paper compares youth with and without Major Depressive Disorder (MDD) in their social and asocial uses of electronic media (EM) and non-electronic media (NEM). In addition this study examines whether recovery from depression is accompanied by changes in media use. The media use and companionship of 108 participants, 47 MDD and 61 non-depressed Controls, were recorded through telephone report. Results show that youth with MDD used EM more in an asocial context than did the Control group both during the depressive episode and after recovery from depression. In addition, NEM use was significantly higher for the Control group than the MDD group after recovery. Time spent with asocial EM is considered as a consequence of the depressive episode and as an aid to recovery supporting the social risk hypothesis of depression. Asocial media use is also considered to be a possible hindrance to recovery. Implications for treatment are discussed
ARCHITECTURAL HERITAGE BUILDING IN THE STATE OF SÃO PAULO: SURVEY AND DIGITAL DOCUMENTATION OF A JESUIT MISSION
Regge Behavior of DIS Structure Functions
Building on previous works of the mid 1960's, we construct an integral
equation for forward elastic scattering (t=0) at arbitrary virtuality Q^2 and
large s=W^2. This equation sums the ladder production of massless intermediate
bosons to all orders, and the solution exhibits Regge behavior. The equation is
used to study scattering in a simple chi^2 phi scalar theory, where it is
solved appoximately and applied to the study of DIS at small x. We find that
the model can naturally describe the quark distribution in both the large x
region and the small x region dominated by Reggeon exchange.Comment: 13 pages with 5 figure
A specific loop in human DNA polymerase mu allows switching between creative and DNA-instructed synthesis
Human DNA polymerase mu (Polμ) is a family X member that has terminal transferase activity but, in spite of a non-orthodox selection of the template information, displays its maximal catalytic efficiency in DNA-templated reactions. As terminal deoxynucleotidyl transferase (TdT), Polμ has a specific loop (loop1) that could provide this enzyme with its terminal transferase activity. When loop1 was deleted, human Polμ lacked TdT activity but improved DNA-binding and DNA template-dependent polymerization. Interestingly, when loop1 from TdT was inserted in Polμ (substituting its cognate loop1), the resulting chimaera displayed TdT activity, preferentially inserting dGTP residues, but had a strongly reduced template-dependent polymerization activity. Therefore, a specialized loop in Polμ, that could adopt alternative conformations, appears to provide this enzyme with a dual capacity: (i) template independency to create new DNA information, in which loop1 would have an active role by acting as a ‘pseudotemplate’; (ii) template-dependent polymerization, in which loop1 must allow binding of the template strand. Recent in vivo and in vitro data suggest that such a dual capacity could be advantageous to resolve microhomology-mediated end-joining reactions
End-bridging is required for pol μ to efficiently promote repair of noncomplementary ends by nonhomologous end joining
DNA polymerase μ is a member of the mammalian pol X family and reduces deletion during chromosome break repair by nonhomologous end joining (NHEJ). This biological role is linked to pol μ's ability to promote NHEJ of ends with noncomplementary 3′ overhangs, but questions remain regarding how it performs this role. We show here that synthesis by pol μ in this context is often rapid and, despite the absence of primer/template base-pairing, instructed by template. However, pol μ is both much less active and more prone to possible template independence in some contexts, including ends with overhangs longer than two nucleotides. Reduced activity on longer overhangs implies pol μ is less able to synthesize across longer gaps, arguing pol μ must bridge both sides of gaps between noncomplementary ends to be effective in NHEJ. Consistent with this argument, a pol μ mutant defective specifically on gapped substrates is also less active during NHEJ of noncomplementary ends both in vitro and in cells. Taken together, pol μ activity during NHEJ of noncomplementary ends can thus be primarily linked to pol μ's ability to work together with core NHEJ factors to bridge DNA ends and perform a template-dependent gap fill-in reaction
The regime of climate-related disturbance and nutrient enrichment modulate macroalgal invasions in rockpools
Patterns of invasion by the seaweeds Grateloupia turuturu Yamada and Sargassum muticum (Yendo) Fensholt under crossed combinations of the regime (mean intensity and temporal variability) of climate-related mechanical disturbance and constant nutrient enrichment were experimentally examined in rockpools in north Portugal. The cover of both species was larger under high compared to low intensity of disturbance, but this effect was enhanced by events more heterogeneously distributed over a period of 19 months. The invasion by G. turuturu was also larger in enriched pools, but only when disturbance was applied at high intensity. The richness of native taxa was increased by high intensity events of disturbance evenly distributed over time and by low intensity events heterogeneously distributed, while no differences were documented for other treatments. Temporal variability of disturbance and nutrients interactively affected the total cover of native taxa and the availability of bare rock in different directions. Enriched conditions increased the space occupancy by natives and reduced substratum availability only when associated to heterogeneous events of disturbance. At the same time, relatively more variable disturbances caused a reduced cover by native taxa and an increased availability of free space, but only under natural nutrient levels. Present findings contribute to understand the conditions that would be more likely to facilitate the spread of G. turuturu and S. muticum under current and predicted scenarios of compounded environmental changes and in relation to traits of recipient systems that are considered relevant for the success of invasions, including the native richness and the degree of usage of resources, i.e. primarily space
Stability of Satellite Planes in M31 II: Effects of the Dark Subhalo Population
The planar arrangement of nearly half the satellite galaxies of M31 has been
a source of mystery and speculation since it was discovered. With a growing
number of other host galaxies showing these satellite galaxy planes, their
stability and longevity have become central to the debate on whether the
presence of satellite planes are a natural consequence of prevailing
cosmological models, or represent a challenge. Given the dependence of their
stability on host halo shape, we look into how a galaxy plane's dark matter
environment influences its longevity. An increased number of dark matter
subhalos results in increased interactions that hasten the deterioration of an
already-formed plane of satellite galaxies in spherical dark halos. The role of
total dark matter mass fraction held in subhalos in dispersing a plane of
galaxies present non trivial effects on plane longevity as well. But any
misalignments of plane inclines to major axes of flattened dark matter halos
lead to their lifetimes being reduced to < 3 Gyrs. Distributing > 40% of total
dark mass in subhalos in the overall dark matter distribution results in a
plane of satellite galaxies that is prone to change through the 5 Gyr
integration time period.Comment: 11 pages, 9 figures, accepted to MNRAS September 22 201
