Like all of Penelope Lively's books, "The Photograph" is concerned with the hold that time past exerts over time present, and the uses and abuses of memory.
In novel after novel, Pat Barker has examined the hold that time past exerts over time present, be it memories of combat haunting soldiers in her "Regeneration" trilogy or family ghosts haunting a couple's marriage in "Another World".
Time and the supernatural are also at the center of her new novel, "Her Fearful Symmetry," an entertaining but not terribly resonant ghost story about two generations of twins, which like all ghost stories, addresses the hold that time past exerts over time present.
Only gradually are the relationships between these characters and their ancestors revealed, resulting in an elliptical, jigsaw puzzle of a narrative that italicizes the hold that time past exerts over time present, and the startling changes that have swept through the reservation and the small towns nearby in the space of a couple of generations.
All of Ms. Morrison's perennial themes are here: lost innocence and the hold that time past exerts over time present; the sufferings sustained by black women at the hands of black men; the fallout that social change and changing attitudes toward race can have on a small community; the possibility of redemption, if past grievances and hurts can somehow be left behind.
The outcome of Irena and Josef's encounter and its fallout on their lives will come as a surprise, but in retrospect will also seem inevitable: the fruit of their shared emotions about returning home and their very different feelings about the hold that time past exerts over time present.
"Home" encapsulates all the themes that have fueled her fiction, from the early novels "Sula" and "The Bluest Eye," through her dazzling masterwork, "Beloved," and more recent, less persuasive books like "Love" and "Paradise": the hold that time past exerts over time present, the hazards of love (and its link to leaving and loss), the possibility of redemption and transcendence.
The effect of aggimpact (_{Y})(t) on Y is exerted over time gradually, depending on speed factor ({upeta }_{Y}): begin{aligned} Y(t + Delta t) = Y t) + {upeta }_{Y}[mathbf{aggimpact}_{Y}(t) - Y t)] Delta t end{aligned} or begin{aligned} mathbf{d}Y t)/mathbf{d}t = {upeta }_{Y}[mathbf{aggimpact}_{Y} tmathbfY t)] end{aligned}.
The relative lack of association in multivariate analysis between independent variables and emotional distress, underlines that each patient exerts over time her own personal capabilities to rescue over time form anxiety and QoL deterioration.
We can further imagine members of a research group, G i, exerting efforts over time, s i, in search of the innovation, so that nicefrac{dalpha_{i}}{dt}=dot{alpha_{i}}=s_{i}.
