Описание: This book is an invitation to come home to your authentic self in a world that is frequently mesmerized by spin, narcissism, fantasy, and exhibitionism. Psychology and classic wisdom literature have, in various ways, long recognized the value for simply becoming who you are (i.e., ordinariness). However, this call is becoming increasingly drowned out by the many other voices that emphasize publicity and image-making over authenticity and humility. Renowned therapist and author Robert Wicks has written The Tao of Ordinariness as a way of beginning to address these tendencies in contemporary society. In this new countercultural work, the strength and joy of exploring who you are - and proceeding to share yourself with others in a way that they too can reclaim themselves - is revisited from a range of vantage points. The author specifically reexamines themes of humility, simplicity, letting go, self-awareness, alonetime, resilience, and mentoring. In an era when people increasingly measure self-worth by external measures, such as the number of likes and views and followers on social media feeds (which have many individuals chasing impossible fantasies and living with a constant fear of missing out), Wicks offers a return to your authentic self.
Описание: Abstract: Cycloadditions involving fluoroallenes are extremely useful mechanistic probes. Due to the high reactivity of these allenes and the small size of their fluorine substituents, cycloadditions of fluoroallenes are free from many of the ambiguities surrounding analogous studies by previous workers. Styrene and 1,1-difluoroallene, DFA, undergo clean reactions between 60o and 100oC to give good yields (approx. 60%) of two cylcloadducts: 2,2-difluoro-3-phenyl-1-methylenecyclobutane (major) and 3-phenyl-1-(difluoromethylene)cyclobutane (minor). Similar experiments comparing the reactions of p-nitro and p-methoxystyrene with the above results give relative reactivities of 2.1 and 1.3, respectively. The 2]2] cycloaddition of DFA with Z-β-deuteriostyrene gives the expected products in an 82:18 ratio with stereochemical ratios of 58:42 and 79:21, respectively, at 80oC. A mechanism involving two kinetically distinguishable diradicals is proposed to rationalize the results. The reaction of DFA with 1-cyanovinyl acetate, a "capto-dative" reagent is also studied and found to give results similar to the styrene reactions. N-Methyl, N-phenyl, and N-(2-naphthyl)-C-phenylnitrones undergo regiospecific C2-C3 dipolar cycloadditions with monofluoroallene, MFA, in nearly quantitative yields at 25oC. The average stereochemical ratio for the two 4-substituted isoxazolidines produced is 84:16 2% with the product from syn addition of MFA in excess. The stereochemical assignments of the products are made with the aid of difference nuclear Overhauser effect (NOE) experiments and an X-ray crystal structure. Extensive solvent and kinetic studies show that these are well-behaved second-order kinetic processes consistent with previously well-studied 1,3-dipolar cycloadditions. The reaction of MFA with diazomethane-d2 strongly favors the product from the syn addition (88:12 ratio), also. Consideration of transition-state dipole-dipole interactions and solvation phenomena show that the factors affecting the stereochemical outcome of all these 1,3-dipolar cycloadditions are extremely subtle. Finally, MFA undergoes Diels-Alder reactions with cyclopentadiene, butadiene, and furan to give a modest preference for the syn adduct (51:49, 59:41, and 63:37, respectively). The results are discussed in terms of a theoretical study done for MFA using INDO calculations.

Описание: For Avery Cullins--library archivist, former teenage runaway, and gay man from a small Southern town--"family" means a live-in boyfriend and a surly turtle. But when his father, a renowned nuclear physicist, commits suicide, Avery's decade-long estrangement from his mother, now hobbled following a stroke, comes to a skidding halt. With his boyfriend's help, Avery takes custody of his mother and the trio heads cross country in a rented U-Haul, back to an apartment in Cleveland and an uncertain future. Their journey soon becomes a pilgrimage into the past when Avery begins sifting through his mother's mementos. What emerges is a story of family, love, and loss as his parents made a home, lost a child, and tested the boundaries of marital love in the 1970s. Meanwhile, in today's uncertain social landscape, Avery must confront his own struggle with a mother who doesn't recognize him and a lover who seeks to claim him for his own.
