چکیده
Abstract. Indonesian public opinion surveys consistently underestimate support for five mid-sized parties: PKB, PKS, NasDem, PAN, and PPP. This paper explores whether this consistent underestimation is the result of social desirability bias, late decisions or mobilization, candidate-driven voter preferences, sampling design. I find some evidence that parties with stronger mobilization networks more candidate-centric strategies are likely to be underestimated. A simulation study suggests design does not systematically disadvantage in question. While bias a possible cause downward scholarly literature casts doubt on undesirability expressed parties. Further research should examine types voters who underestimated might harder reach surveys. Public pollsters consider noting statements these have tended outperform their polls election day. Keywords: surveys; parties; bias; pollster; design; Indonesia. Abstrak. Survei-survei opini publik Indonesia pra-pemilu secara konsisten menemukan dukungan kepada lima partai menengah: dan PPP cenderung lebih rendah dibanding hasil aktual pemilu.

متن کاملWhy do decapod crustaceans prefer small-sized molluscan prey?
A survey of studies examining crab and lobster predation on hard-shelled molluscs indicated that most predators prefer small-sized prey when offered a range of sizes. I suggest that this pattern of preference for small-sized prey can be explained by considering the mechanical cost of predation. If predation costs are assumed to be non-renewable, then the probability of exhausting them can be in...
