Relationship as teacher of sustainability: Post-individualist education

In the face of destructive human presence, sustainability has become a prominent and central theme of the contemporary environmental and wellbeing discourse. Our chapter takes the current environmental and sociopolitical challenges humanity faces as our species’ developmental issue precipitated by the bonding rupture between human beings and other beings. We propose that the sustainability discourse be taken in the direction of healing the wounds of bonding rupture and facilitating the evolution of human consciousness and development of a more mature identity. We posit that the latter is concomitant with overcoming materialistic individualism and moving towards the relational integration of self, community, and world. We make the case that these relational practices are intrinsic to evolving and developing sustainable humanity. In particular, this chapter shows, by way of narrative illustrations, how we may create teaching and learning environments in schools and other institutions that are conducive to experiencing and internalizing a relational sense of self

The Effect of Childhood Emotional Maltreatment on Romantic Relationships in Young Adulthood: A Double Mediation Model Involving Self-Criticism and Attachment

Objective: Despite growing recognition of the importance of childhood emotional maltreatment (CEM) on the development of psychopathology, very few studies have addressed its impact on adult romantic relationship functioning, particularly among otherwise relatively well-functioning individuals. In an attempt to further elucidate the mechanism underlying the negative impact of CEM on romantic relationships, we tested an integrative mediational model linking CEM to romantic relationships through the impact of CEM on the development of self-criticism and adult attachment. Recent work in this context suggests that while self-criticism concerns broad cognitive-affective schemas related to achievement and failure, attachment avoidance assesses the expression of these broad schemas in close relationships (Luyten & Blatt, 2011; Sibley & Overall, 2008, 2010). Method: This hypothesized mediational model was examined in a sample of young adult undergraduates (N = 99, 85 female), using structural equation modeling. Results: The mediational model was in large part supported. Attachment avoidance, but not attachment anxiety, fully accounted for the mediating role of self-criticism in the relationship between CEM and romantic relationship satisfaction, even when controlling for the potential role of concurrent levels of posttraumatic stress disorder severity. Conclusions: Understanding the long-term psychological dynamics related to CEM and identifying mediating vulnerability factors—self-criticism and attachment avoidance—might have implications for both the assessment and treatment of individuals with a history of CEM, particularly as effective interventions to address self-criticism and attachment issues are available

Cognitive Sub-Nyquist Hardware Prototype of a Collocated MIMO Radar

We present the design and hardware implementation of a radar prototype that demonstrates the principle of a sub-Nyquist collocated multiple-input multiple-output (MIMO) radar. The setup allows sampling in both spatial and spectral domains at rates much lower than dictated by the Nyquist sampling theorem. Our prototype realizes an X-band MIMO radar that can be configured to have a maximum of 8 transmit and 10 receive antenna elements. We use frequency division multiplexing (FDM) to achieve the orthogonality of MIMO waveforms and apply the Xampling framework for signal recovery. The prototype also implements a cognitive transmission scheme where each transmit waveform is restricted to those pre-determined subbands of the full signal bandwidth that the receiver samples and processes. Real-time experiments show reasonable recovery performance while operating as a 4x5 thinned random array wherein the combined spatial and spectral sampling factor reduction is 87.5% of that of a filled 8x10 array.Comment: 5 pages, Compressed Sensing Theory and its Applications to Radar, Sonar and Remote Sensing (CoSeRa) 201

Low Communication Complexity Protocols, Collision Resistant Hash Functions and Secret Key-Agreement Protocols

We study communication complexity in computational settings where bad inputs may exist, but they should be hard to find for any computationally bounded adversary. We define a model where there is a source of public randomness but the inputs are chosen by a computationally bounded adversarial participant after seeing the public randomness. We show that breaking the known communication lower bounds of the private coins model in this setting is closely connected to known cryptographic assumptions. We consider the simultaneous messages model and the interactive communication model and show that for any non trivial predicate (with no redundant rows, such as equality): 1. Breaking the $\Omega(\sqrt n)$ bound in the simultaneous message case or the $\Omega(\log n)$ bound in the interactive communication case, implies the existence of distributional collision-resistant hash functions (dCRH). This is shown using techniques from Babai and Kimmel (CCC \u2797). Note that with a CRH the lower bounds can be broken. 2. There are no protocols of constant communication in this preset randomness settings (unlike the plain public randomness model). The other model we study is that of a stateful ``free talk , where participants can communicate freely before the inputs are chosen and may maintain a state, and the communication complexity is measured only afterwards. We show that efficient protocols for equality in this model imply secret key-agreement protocols in a constructive manner. On the other hand, secret key-agreement protocols imply optimal (in terms of error) protocols for equality
