Considering Improvisation: Play,Transitional Space,and Discovery

This article explores the concept of improvisation in the therapeutic setting as a complex construction when elaborated in the idiom of jazz music. A composite clinical case is offered that illustrates an impasse and how improvisational thinking offers a way forward. Improvisation has recently been conceptualized through the metaphor of theater improvisation, dance, and rhythm. The therapeutic hour is considered an improvisational dialogue with the main theme (melody) and counter melodies, and harmonic possibilities that underlie the rhythmic pulse of the hour. Improvisation requires a reflective/interpretive process that draws on patterns, structures, and experiences reformulated in the relational field of the participants. The client initiates the call and response pattern, from which improvisation emerges as a mutual process of discovery. A more relaxed, receptive, and reflective posture extends Winnicott’s 1971 notion of play to integrate classic understanding and relational interaction.     

Objective Tests versus Subjective tests

objective test has only one correct answer, while subjective test has a range of possible answers. Because of this feature, reliability will not be difficult to achieve in the marking of the objective item, while the marking of the subjective items is reliable. On the whole, a good test must contain both subjective and objective test items.

Social security reforms in Kenya: Towards a workerist or a citizenship‐based system?

With social security provisions in Kenya remaining under‐reported in the more recent literature, this overview covers recent reforms in key areas of the country's social security system. In the health sector and in old‐age pension provision social security is still mainly workerist (biased toward those in formal employment), and attempts to expand coverage have had limited effect only – cash transfer programmes, for instance, have been expanded but in practice they do not universally cover the entitled categories. Thus, although the Kenyan social security system now has a considerable pro‐poor social assistance component it remains biased toward those in formal employment, to the benefit of the highest income quintile.

Abstract

Many clients relate in ways that elicit emotional responses in practitioners and may also feel pressure to intervene when appropriate action is not yet clear. Practitioners must develop sufficient self-awareness so their own reactions do not interfere with the work they do with clients. Educators exhort their students to be self-aware, but locating methods that foster the capacity can be difficult. Infant observation is an elegant training model that helps to develop self-awareness. The method described here makes use of regular observation, supportive small groups, and repeated detailed examination of what is seen in training both generalist and specialized practitioners. It has become a prototype for the observational study of several kinds of specific populations. Because it attends to people in their own environments and demonstrates a flexible, reflective, multi-modal manner of information-gathering, infant observation is particularly useful in the education of social work practitioners.     

India's Mahatma Gandhi National Rural Employment Act: Assessing the quality of access and adequacy of benefits in MGNREGS public works

The extension of social protection to all has become a central policy objective, both nationally and internationally. A considerable number of middle‐ and low‐income countries have undertaken substantial efforts to extend social protection, while the international community reaffirmed its commitment to the extension of social protection through the adoption of the ILO Recommendation concerning National Floors of Social Protection, No. 202 (2012). This article reviews the legal provisions and the implementation of the Indian Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), legislated in 2005, and does so in the light of the more recent provisions of ILO Recommendation No. 202. Since its introduction ten years ago, MGNREGA has provided a source of income to rural workers, increased wage rates, achieved high female participation rates and created durable assets. India's local governance bodies, Panchayati Raj Institutions (PRI), have been empowered and involved in the processes of planning and monitoring. However, despite successes, there have been considerable shortcomings in implementation. This article highlights two central themes: first, the innovative policy framework of the Act, which brings together rights‐based entitlements, demand‐driven employment, and citizen‐centred monitoring. Second, it assesses the accessibility and adequacy of benefits in the implementation of MGNREGA. We conclude that MGNREGA offers potential for South‐South learning, both in terms of policy‐design and implementation.     

From “Either‐Or” to “When and How”: A Context‐Dependent Model of Culture in Action

In this article, I outline a framework for the sociological study of culture that connects three intertwined elements of human culture (cultural motivations, resources, and meanings) and demonstrates the concrete contexts under which each most critically influences actions and their subsequent outcomes. In contrast to models that cast motivations, resources, and meanings as competing explanations of how culture affects action, I argue that these are fundamental constituent elements of culture that are inseparable, interdependent, and simultaneously operative. Which element provides the strongest link to action, and how this link operates, must be understood as a function of the actor's position within wider social contexts. I argue that on average motivations have the most discernable link to action within a social strata, cultural resources provide the strongest link across strata, and meanings have the greatest direct influence when codified and sanctioned. I then offer a reframing and synthesis that reintegrates previously “competing” theories of culture into a more holistic context‐dependent model of culture in action. Finally, I use evidence from prior empirical research, as well as new data from an ongoing ethnographic study of health behaviors among the aged, to show how various elements of culture are concretely linked to action in eight different social contexts. In doing so, I provide a roadmap for the transition out of the “either‐or” logic underlying much of cultural theory and reemphasize the importance of the classical sociological concern for “when” and “how” various aspects of culture influence action and outcomes in concrete social contexts.     

The gender gap in pensions in Latin America

Lower female lifetime labour market participation rates, greater interruptions during their working lives, and wage gaps contribute to create gender gaps in pensions at the time of retirement. The design of social security systems may reinforce or attenuate these gaps. This article provides new evidence on gender gaps in access to pensions and in pension income in four Southern Cone countries in Latin America and analyses their evolution between 2000 and 2013, showing significant improvements in both gaps, with differential patterns by countries. The decrease in the gender gap in pension income has been particularly significant in Argentina and Brazil. In both cases, the largest increases in pension values during the period correspond to the lowest income percentiles, where women are overrepresented. The application of redistributive policies in these countries, aimed at reducing poverty and inequality but not necessarily focused on gender equity, has had positive and probably unintended consequences in terms of reduction in gender gaps in pensions.     

A Man Can be Destroyed but Not Defeated

Santiago,the main hero in the Old Man and the Sea is characterized as someone struggling against defeat. He has gone eighty-four days without catching a fish,the sail of his skiff resembles "the flag of permanent defeat." But the old man refuses defeat at every turn:he resolves to sail out beyond the other fishermen to where the biggest fish promise to be. He lands the marlin,tying his record of eighty-seven days after a brutal three-day fight,and he continues to ward off sharks from stealing his prey,even though he knows the battle is useless. He establishes a great hero:a man can be destroyed but not defeated.
