Human sexuality: the controversy continues

Sex education should be an integrated component of population education programs in the Philippines. There are, however, a variety of objections to this approach, which are linked to proposals that sex education is more relevant to biology and medicine curriculums. The Population Education Program of the Philippines conducted a study of 2093 parents and 4550 teachers to determine who registered objections to teaching certain population education content, what they objected to, and why such objections were raised. Findings show that only 3% of the sample reacted unfavorably to the inclusion of controversial topics, such as sex terms, illustrations of sex organs and the naming of contraceptive devices. The issues remaining to be solved are: content, terminology, teacher competence, parents' involvement, and teaching aids.     

Factors Preventing Gridlock in Chilean Couples’ Relationships Based on the Discourse of Couples Therapists and Highly Adjusted Couples

The term gridlock describes the occurrence of rigid patterns in couples’ conflict. This study aimed to describe strategies of conflict resolution and gridlock prevention from the perspectives of couples and couple therapists. Participants were couple therapists and highly adjusted couples scored by the dyadic adjustment scale (DAS), distributed according to traditional and non‐traditional position in life and duration of relationships. Conflict gridlock scenarios were used to create video stimulus that were presented to participants. A qualitative methodology was used to analyse couples’ and therapists’ commentaries on the scenarios. Results showed differences in preventing conflict gridlock among sub‐groups of couples. Long‐term traditional couples focused on loyalty to a common project and value sacrificing to a higher good; long‐term non‐traditional couples prioritised caring and validating the bond in the relationship. Short‐term traditional couples focused on mutual love and the relief of hurt while short‐term non‐traditional couples supported the value of equity.     

An application of catastrophe theory to management science process

Practicing management scientists often complain of the alleged irrational behavior on the part of the managers they are trying to serve, particularly when a manager suddenly and unexpectedly shifts behavior from one of support to one of resistance. The authors feel such behavior is only believed to be irrational because the management scientist is using the wrong mental model when projecting past behavioral patterns into the future. This paper attempts to solve this problem by using the newly developed catastrophe theory to develop a different model where sudden shifts in behavior are considered perfectly rational and explainable. The basic implication that is drawn from this new model is that successful implementation of management science depends on a sequence of interactions with the ultimate model user and that care in the structuring of these interactions can greatly enhance the probability of eventual user acceptance.     

Econometric analysis and managerial decision making

Econometric analysis is concerned with the quantitative relationships between economic variables and it can provide an important input into the decision making process of managers. Typically econometrics differs from other apsects of management science in that it considers problems primarily, though not exclusively, from a background of economics rather than of other disciplines and behaviour is usually dealt with at higher levels of data aggregation than the individual firm.This paper considers some applications of typical econometrics to the general area of managerial decision making, where primarily the techniques have a role to play in assisting the general process of data analysis. Initially discussion is pointed towards the use of the analysis for predictive purposes and the contrast with time series methods. Subsequently examples are presented where the objective is to obtain a better understanding of individual economic relationships that aim to be important inputs into the decision making process, for example cost and revenue analysis. Finally, an example is given of how these ideas contribute more generally to the activity of model building for the firm as a whole both for the purpose of forecasting and policy simulation.     

DOES HIGH COST OF MORTGAGE DEBT EXPLAIN WHY YOUNG ADULTS LIVE WITH THEIR PARENTS?

Young adults leave their parents' homes at a higher rate in Northern Europe or in the United States than in Southern Europe, with broad implications on labor market mobility and on fertility. We assess if differences in household formation are associated to differences in access to credit by estimating the impact of the cost of a mortgage on the probability that a young adult leaves his or her parents' home. Exogenous changes in the cost of credit are identified using the reform in 1998 and the cancellation in 2002 of Crédito Bonificado, a Portuguese program that provided four different reductions of the interest rate of mortgages signed by low‐ and medium‐income youth. Using a unique data set that links administrative records of debt with the 1998–2004 waves of the Employment Survey, we document three findings. First, borrowing among young adults fell when borrowing costs increased. Second, the elasticity of new household formation with respect to net interest rates lies between −0.8 and −3.3. Third, young adults responded to the increase in mortgage costs by delaying home purchases or by reducing the quality of housing services purchased, but there was only a modest increase of the probability of renting a new accommodation.

Local volunteers respond to the Rena oil spill in Maketū, New Zealand

Following the MV Rena grounding and oil spill in the Bay of Plenty, New Zealand in October 2011, the Māori community of Maketū were quick to respond to the arrival of oil on their beaches. They asserted their rangatiratanga by establishing their marae as a base and successfully coordinated a clean-up by more than 450 volunteers, feeding these volunteers every day. We interviewed 11 clean-up leaders and volunteers in Maketū to gather information about how the oil spill affected people in the community and how they ensured the success of their clean-up efforts. Many volunteers returned to help with the clean-up day after day over several weeks. Concepts of kaitiakitanga and manaakitanga underpinned the work of the Maketū clean-up organisers. Participants attributed the success of the Maketū clean-up to the speed with which they responded, the support they received from their community and local businesses, and their local knowledge.
